Most checkpoint inhibitor–induced rheumatic complications in cancer patients can be treated successfully with corticosteroids, albeit often at considerably higher doses than rheumatologists typically use in managing rheumatoid arthritis, Eric M. Ruderman, MD, observed at the 2021 Rheumatology Winter Clinical Symposium.

“In RA, we’re all used to the idea that 5 or 10 mg of corticosteroids per day can make a tremendous difference. That’s not always the case here. Patients who develop rheumatic immunotherapy-related adverse events often require 20-30 mg/day to get symptoms under control,” according to Dr. Ruderman, professor of medicine (rheumatology) at Northwestern University, Chicago.

This may be in part because oncologists typically don’t refer affected patients to rheumatologists early on. Guidelines from the National Comprehensive Cancer Network and other oncology groups suggest referral only once a patient develops grade 3 immunotherapy-related rheumatic adverse events, meaning the symptoms significantly impair daily activities, he explained.

Checkpoint inhibitors, which induce T-cell activation to fight the patient’s malignancy, can produce a plethora of off-target effects. These adverse events may involve the skin, heart, lungs, kidneys, eyes, blood, GI tract, and endocrine organs. The drugs also can cause rheumatic or neurologic complications. The most common of these adverse events are colitis and rash. Next most common are arthritis and arthralgia. Rheumatic side effects are most common as a consequence of immunotherapy using a CTLA4 (cytotoxic T-lymphocyte-associated protein 4) inhibitor, but can also occur in association with programmed cell death protein 1 (PD-1) inhibitors and PD-ligand 1 inhibitors. Arthritis and other rheumatic adverse events are more common in patients undergoing combination therapy.

Some form of frank inflammatory arthritis occurs in 5%-10% of cancer patients undergoing checkpoint inhibitor therapy. This can manifest as an RA-like polyarthritis, spondyloarthritis, polymyalgia rheumatica, necrotizing myositis, or vasculitis. Arthralgia occurs in up to 40% of treated patients.

This immunotherapy-related arthritis is typically more inflammatory than RA. It also has a much more abrupt onset. It is usually seronegative and has no gender predisposition, and the limited available evidence to date suggests there is no increased risk of this complication in checkpoint inhibitor–treated patients with a history of prior rheumatic disease, according to Dr. Ruderman.
 

Delayed onset and resolution of rheumatologic immune-related adverse events

“Onset and resolution of rheumatologic adverse events with immunotherapy may be delayed. This is an important point: While skin rash and colitis often show up pretty early in the course of immunotherapy, some of the arthritic events can happen later. They can actually continue after the immunotherapy is stopped,” the rheumatologist said.

Indeed, a retrospective nationwide Canadian study of 117 patients at nine academic centers who developed 136 rheumatic immune-related adverse events in conjunction with cancer immunotherapy found that the mean time to the first such event was 6.8 months into checkpoint inhibitor therapy. The most common rheumatic complication was symmetric polyarthritis, affecting 45 patients. Other rheumatologic immune-related complications included polymyalgia rheumatica in 17 patients, noninflammatory musculoskeletal symptoms in 18, and myositis in 9.

Seventy-six patients were treated with prednisone for a mean of 8.4 months at a maximum dose of 60 mg/day. Forty-two moved up the treatment ladder to conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) to manage their symptoms. Only two patients required escalation to biologic therapy. A reassuring finding in this relatively small study was that treatment of the patients’ rheumatic complications didn’t appear to worsen the tumor response to immunotherapy: Twenty-three patients experienced tumor progression prior to treatment of their rheumatic disorder, and 14 did so following treatment.
 

Flares of preexisting rheumatic diseases

These tend to occur much earlier in the course of immune checkpoint inhibitor therapy for cancer than de novo immunotherapy-related rheumatic adverse events. In a retrospective Australian study of 12 cancer patients with preexisting rheumatic disease before going on a PD-1 inhibitor and 24 others with no such history, all of whom developed rheumatic adverse events while on the checkpoint inhibitor, the mean time to a flare of preexisting rheumatic disease was 6.2 weeks, compared to 21.5 weeks in patients who experienced a de novo rheumatic adverse event.

Dr. Ruderman supports recommendations from the European Alliance of Associations for Rheumatology (EULAR) for the management of rheumatic immune-related adverse events due to cancer immunotherapy, even though the underlying level of evidence is fairly weak. The recommendations call for the use of csDMARDs when corticosteroids don’t adequately control symptoms. And when the response to csDMARDs is insufficient, the next step is a biologic, preferably a tumor necrosis factor inhibitor or interleukin-6 inhibitor.

“At our institution, the oncologists are a little bit nervous about using biologics in cancer patients, but I think more and more they’re going to have to accept it. And so far there isn’t a ton of evidence that suggests the addition of biologics interferes with the efficacy of the immunotherapy,” the rheumatologist said.

He underscored the critical importance of one of the overarching principles of the EULAR guidelines: the need for interdisciplinary coordination between rheumatologists and oncologists regarding the problem of rheumatologic immune-related adverse events.

“Oncologists aren’t good at managing inflammatory arthritis. I think they really need us,” he said.

Dr. Ruderman reported serving as a consultant to and/or receiving a research grant from nine pharmaceutical companies.

Patients with rheumatoid arthritis are often eager to try dietary interventions in an effort to improve their symptoms. For guidance, they turn to their rheumatologists, who typically can offer little in terms of concrete evidence-based recommendations. That’s because their training didn’t emphasize the role of nutrients in rheumatic diseases, the scientific evidence has historically been sketchy, and the topic of diet and disease is rife with fad diets, inflated Internet claims, and hucksterism.

Bruce Jancin/MDedge News

But that’s changing. Indeed, recent annual meetings of the American College of Rheumatology have featured randomized, controlled trials that bring welcome rigor to the field and provide findings of practical interest to clinicians and their patients, Orrin M. Troum, MD, said at the 2021 Rheumatology Winter Clinical Symposium.

He highlighted some of this work, including positive randomized trials of the dietary supplements Biqi – a traditional Chinese herbal medicine – as well as turmeric, along with reported progress in efforts to design a palatable anti-inflammatory diet that favorably alters the gut microbiome and systemic metabolome while improving clinical outcomes in patients with RA.

Dr. Troum, a rheumatologist at the University of Southern California, Los Angeles, and in private practice in Santa Monica, described a typical patient encounter in his clinic that appeared to resonate with his audience from throughout the country: “You can tell people to take another medicine and they’ll start shaking their head no before you’re finished. But when you say there are natural supplements that can help you, they’re saying ‘Yes!’ ”
 

RA improvement on an ITIS diet

Many physicians recommend a Mediterranean-style diet, first popularized in the landmark Seven Countries Study launched by the late Dr. Ancel Keys. This familiar plant-based regimen emphasizes liberal consumption of extra-virgin olive oil, legumes, fruits and vegetables, whole grains, fish, nuts, and moderate alcohol intake, with very limited intake of red and processed meats, refined grains, and sugar. There is strong evidence that the Mediterranean diet is cardioprotective, which is relevant to patients with RA since they are known to be at elevated cardiovascular risk.

However, investigators at the University of California, San Diego, became convinced that the Mediterranean diet is lacking in key anti-inflammatory ingredients from other parts of the world. These include ginger, green tea, black pepper, turmeric, miso, flax seeds, and tahini, all of which are backed by evidence – from animal models and/or interventional diet studies in patients – that suggests beneficial effects in pain and joint swelling in RA. The researchers also suspected that certain vegetables embraced in the Mediterranean diet – notably eggplant, tomatoes, and potatoes – might be problematic for RA patients because they contain solanine, thought to increase intestinal permeability, which might have arthritogenic effects on the gut microbiome.

The investigators set out to develop an anti-inflammatory diet they call the ITIS diet, essentially tweaking the Mediterranean-style diet by incorporating these additions and subtractions. Importantly, they designed the ITIS diet in conjunction with a multiracial local group of RA patients strongly enthusiastic about the potential for dietary interventions aimed at improving their symptoms. The patients provided feedback that enabled the investigators to fine-tune the anti-inflammatory diet so as to boost palatability and acceptance.

As an illustrative example of the ITIS diet, a typical day might start off with a homemade smoothie of parsley, pineapple, strawberries, and water, followed by a breakfast consisting of one or two corn tortillas spread with avocado, linseed oil, and sesame seeds, accompanied by green tea. Following a mid-morning snack of plain Greek-style yogurt, lunch might be a choice of a large salad, legumes with vegetables, or whole grains with vegetables. For the afternoon snack: four walnuts plus mango, banana, pear, papaya, apple, or pineapple. And for dinner, the options are vegetable soup and a protein; salad plus a protein; or miso soup, cooked vegetables, and a protein.

At the 2020 ACR annual meeting, Roxana Coras, MD, presented the positive findings of an open-label, pilot study of the ITIS diet in which 17 patients with active RA involving at least three tender and three swollen joints adopted the diet for 2 weeks . The ITIS diet turned out to be not too much of a stretch for Southern California RA patients interested in dietary complementary and alternative medicine. Many had already adopted some elements of the anti-inflammatory diet. Dietary adherence in the study was good, as monitored in food logs and by mass spectrometry metabolic profiling of fecal and plasma samples.

Eleven patients were categorized as responders to the anti-inflammatory diet as defined by at least a 50% improvement in pain scores from baseline to 2 weeks; six patients were nonresponders. In the overall study population, mean pain scores on a 0-10 visual analog scale improved from 3.9 to 2.45. Scores on the Clinical Disease Activity Index (CDAI) also improved significantly on the ITIS diet, from 29 to 12.7, reported Dr. Coras, a rheumatologist at the University of California, San Diego.

The mechanisms for the clinical improvement on the diet are under study. Significant differences in the gut microbiome and metabolome were seen between the responders and nonresponders. For example, Mollicutes were increased and Coriobacteriales decreased in clinical responders versus nonresponders. A significant increase in circulating levels of anti-inflammatory oxylipins was also seen in responders. Longer-term controlled studies of the ITIS diet are planned.

Biqi is big in China, gaining ground in the U.S.

Ayurvedic medicine in India and Chinese traditional herbal medicine have richly documented 4,500-year histories.

“It’s so common in my neck of the woods, where there are large Asian communities, for Chinese or Korean or Japanese or Indian medicines to be combined with our medicines. And if you don’t ask about them, you’re never going to find out what these patients are taking,” Dr. Troum said.

If they’re taking Biqi capsules, readily available on the Internet, be advised that there is randomized trial evidence to show that they’re using an efficacious and safe herbal medicine for RA. In China, the combination of Biqi capsules and a conventional disease-modifying antirheumatic drug such as methotrexate is now widely used for treatment of RA. And at the 2019 ACR annual meeting, Runyue Huang, MD, of Guangzhou University of Chinese Medicine, presented the results of a 24-week, randomized, multicenter, open-label clinical trial in which 70 RA patients were assigned to methotrexate plus a 1.2-g Biqi capsule twice daily or to methotrexate plus leflunomide (Arava) at 20 mg/day. The primary outcome – achievement of a 20% improvement in the ACR criteria, or ACR20 response, at week 24 – was achieved in 77% of the Biqi group, not significantly different from the 83% rate in the comparator group. However, the Biqi plus methotrexate group had significantly fewer adverse events and the combination was better tolerated than was leflunomide plus methotrexate.

In addition, a systematic review of earlier clinical trials concluded that Biqi in combination with methotrexate was more effective and had fewer adverse events than methotrexate alone.

“Biqi capsule with methotrexate appears to be a promising combination for RA if you can rest assured that what’s found in the Biqi capsule is exactly what they say. And that’s the main issue: You don’t really know what you’re getting unless it’s in a trial,” Dr. Troum said.

American RA patients embrace turmeric

Turmeric has played a prominent role in Ayurvedic medicine for millenia. The most medicinally important component of turmeric root is curcumin, which has potent anti-inflammatory and antioxidant properties. Americans with RA have gotten on the bandwagon, as demonstrated in a survey of 291 patients with RA or psoriatic arthritis presented at ACR 2020 by investigators from the University of Central Florida, Orlando. Among the respondents, 37% reported having taken curcumin, with no predilection based upon age, gender, or diagnosis. Fifty-nine percent took their curcumin in the form of capsules, with the rest took it as an oil or powder. Fifty-four percent got their curcumin at a local store.

Thirty-six percent of curcumin users reported improvement in pain after going on the herbal supplement. Twenty-five percent reported reduced swelling, 23% had less stiffness, and 16% reported improvement in fatigue. Patients taking 200-1,000 mg/day reported significantly greater improvement in symptoms than that of those taking less than 200 mg/day. Onset of benefits was slow: Patients on curcumin for a year or longer reported greater symptomatic improvement than did those on the supplement for less time.

Asked what he recommends to his RA patients who express interest in supplements aimed at achieving symptomatic improvement, Dr. Troum replied that he’s comfortable suggesting curcumin capsules at 500 mg twice daily, which should be labeled as containing black pepper extract to aid in absorption. He also recommends fish oil both for its cardioprotective benefits and because of randomized trial evidence that it enhances the chances of achieving ACR remission in patients on conventional disease-modifying antirheumatic drugs.
 

What about osteoarthritis?

Investigators with the National Institutes of Health–sponsored Osteoarthritis Initiative found in an analysis of the dietary patterns of 2,757 patients with mild to moderate knee OA who were followed annually for 6 years that participants could be grouped into two broad categories: Those who consumed what was termed the prudent diet, with high intake of fruits and vegetables, legumes, fish, and whole grains; and fans of the Western diet, characterized by lots of red meat, refined grains, and liberal consumption of French fries. Knee symptoms increased over time in dose-response fashion with greater adherence to the Western diet and decreased with higher prudent diet scores.

Also at ACR 2019, Australian investigators presented the results of the double-blind CurKOA trial, in which 70 participants with knee OA and moderate baseline effusion/synovitis by ultrasound were randomized to take a capsule containing 500 mg of turmeric root extract or identical placebo twice daily for 12 weeks. The group on turmeric plant extract experienced 9.11-mm greater reduction in knee pain on a 0- to 100-mm visual analog scale than did controls, which translates to a moderate standard effect size deemed by investigators to be “greater than other conventional pharmacologic therapies.” Overall, 63% of the turmeric group achieved a treatment response by OARSI-OMERACT criteria, a significantly better outcome than the 38% rate in controls. However, there was no significant between-group difference in knee structural measures as assessed by MRI in this relatively brief trial.

Anne M. Stevens, MD, PhD, senior director of immunology translational medicine at Janssen Pharmaceuticals and a pediatric rheumatologist at Seattle Children’s Hospital, rose from the audience to share that she recommends that her patients on high-dose curcumin not take NSAIDs because the two share a similar mechanism of action involving COX-2 inhibition, and the combination might therefore increase bleeding risk. But Dr. Troum said he hasn’t seen any increase in bleeding in his patients on both agents.

Dr. Troum has financial relationships with numerous pharmaceutical companies, but reported having no financial conflicts of interest regarding his presentation.

Among the respondents, 37% reported having taken curcumin, with no predilection based upon age, gender, or diagnosis. Fifty-nine percent took their curcumin in the form of capsules, with the rest took it as an oil or powder. Fifty-four percent got their curcumin at a local store.

Thirty-six percent of curcumin users reported improvement in pain after going on the herbal supplement. Twenty-five percent reported reduced swelling, 23% had less stiffness, and 16% reported improvement in fatigue. Patients taking 200-1,000 mg/day reported significantly greater improvement in symptoms than that of those taking less than 200 mg/day. Onset of benefits was slow: Patients on curcumin for a year or longer reported greater symptomatic improvement than did those on the supplement for less time.

Asked what he recommends to his RA patients who express interest in supplements aimed at achieving symptomatic improvement, Dr. Troum replied that he’s comfortable suggesting curcumin capsules at 500 mg twice daily, which should be labeled as containing black pepper extract to aid in absorption. He also recommends fish oil both for its cardioprotective benefits and because of randomized trial evidence that it enhances the chances of achieving ACR remission in patients on conventional disease-modifying antirheumatic drugs.
 

What about osteoarthritis?

Investigators with the National Institutes of Health–sponsored Osteoarthritis Initiative found in an analysis of the dietary patterns of 2,757 patients with mild to moderate knee OA who were followed annually for 6 years that participants could be grouped into two broad categories: Those who consumed what was termed the prudent diet, with high intake of fruits and vegetables, legumes, fish, and whole grains; and fans of the Western diet, characterized by lots of red meat, refined grains, and liberal consumption of French fries. Knee symptoms increased over time in dose-response fashion with greater adherence to the Western diet and decreased with higher prudent diet scores.

Also at ACR 2019, Australian investigators presented the results of the double-blind CurKOA trial, in which 70 participants with knee OA and moderate baseline effusion/synovitis by ultrasound were randomized to take a capsule containing 500 mg of turmeric root extract or identical placebo twice daily for 12 weeks. The group on turmeric plant extract experienced 9.11-mm greater reduction in knee pain on a 0- to 100-mm visual analog scale than did controls, which translates to a moderate standard effect size deemed by investigators to be “greater than other conventional pharmacologic therapies.” Overall, 63% of the turmeric group achieved a treatment response by OARSI-OMERACT criteria, a significantly better outcome than the 38% rate in controls. However, there was no significant between-group difference in knee structural measures as assessed by MRI in this relatively brief trial.

Anne M. Stevens, MD, PhD, senior director of immunology translational medicine at Janssen Pharmaceuticals and a pediatric rheumatologist at Seattle Children’s Hospital, rose from the audience to share that she recommends that her patients on high-dose curcumin not take NSAIDs because the two share a similar mechanism of action involving COX-2 inhibition, and the combination might therefore increase bleeding risk. But Dr. Troum said he hasn’t seen any increase in bleeding in his patients on both agents.

Dr. Troum has financial relationships with numerous pharmaceutical companies, but reported having no financial conflicts of interest regarding his presentation.

Patients with rheumatoid arthritis are often eager to try dietary interventions in an effort to improve their symptoms. For guidance, they turn to their rheumatologists, who typically can offer little in terms of concrete evidence-based recommendations. That’s because their training didn’t emphasize the role of nutrients in rheumatic diseases, the scientific evidence has historically been sketchy, and the topic of diet and disease is rife with fad diets, inflated Internet claims, and hucksterism.

Bruce Jancin/MDedge News

But that’s changing. Indeed, recent annual meetings of the American College of Rheumatology have featured randomized, controlled trials that bring welcome rigor to the field and provide findings of practical interest to clinicians and their patients, Orrin M. Troum, MD, said at the 2021 Rheumatology Winter Clinical Symposium.

He highlighted some of this work, including positive randomized trials of the dietary supplements Biqi – a traditional Chinese herbal medicine – as well as turmeric, along with reported progress in efforts to design a palatable anti-inflammatory diet that favorably alters the gut microbiome and systemic metabolome while improving clinical outcomes in patients with RA.

Dr. Troum, a rheumatologist at the University of Southern California, Los Angeles, and in private practice in Santa Monica, described a typical patient encounter in his clinic that appeared to resonate with his audience from throughout the country: “You can tell people to take another medicine and they’ll start shaking their head no before you’re finished. But when you say there are natural supplements that can help you, they’re saying ‘Yes!’ ”
 

RA improvement on an ITIS diet

Many physicians recommend a Mediterranean-style diet, first popularized in the landmark Seven Countries Study launched by the late Dr. Ancel Keys. This familiar plant-based regimen emphasizes liberal consumption of extra-virgin olive oil, legumes, fruits and vegetables, whole grains, fish, nuts, and moderate alcohol intake, with very limited intake of red and processed meats, refined grains, and sugar. There is strong evidence that the Mediterranean diet is cardioprotective, which is relevant to patients with RA since they are known to be at elevated cardiovascular risk.

However, investigators at the University of California, San Diego, became convinced that the Mediterranean diet is lacking in key anti-inflammatory ingredients from other parts of the world. These include ginger, green tea, black pepper, turmeric, miso, flax seeds, and tahini, all of which are backed by evidence – from animal models and/or interventional diet studies in patients – that suggests beneficial effects in pain and joint swelling in RA. The researchers also suspected that certain vegetables embraced in the Mediterranean diet – notably eggplant, tomatoes, and potatoes – might be problematic for RA patients because they contain solanine, thought to increase intestinal permeability, which might have arthritogenic effects on the gut microbiome.

The investigators set out to develop an anti-inflammatory diet they call the ITIS diet, essentially tweaking the Mediterranean-style diet by incorporating these additions and subtractions. Importantly, they designed the ITIS diet in conjunction with a multiracial local group of RA patients strongly enthusiastic about the potential for dietary interventions aimed at improving their symptoms. The patients provided feedback that enabled the investigators to fine-tune the anti-inflammatory diet so as to boost palatability and acceptance.

As an illustrative example of the ITIS diet, a typical day might start off with a homemade smoothie of parsley, pineapple, strawberries, and water, followed by a breakfast consisting of one or two corn tortillas spread with avocado, linseed oil, and sesame seeds, accompanied by green tea. Following a mid-morning snack of plain Greek-style yogurt, lunch might be a choice of a large salad, legumes with vegetables, or whole grains with vegetables. For the afternoon snack: four walnuts plus mango, banana, pear, papaya, apple, or pineapple. And for dinner, the options are vegetable soup and a protein; salad plus a protein; or miso soup, cooked vegetables, and a protein.

At the 2020 ACR annual meeting, Roxana Coras, MD, presented the positive findings of an open-label, pilot study of the ITIS diet in which 17 patients with active RA involving at least three tender and three swollen joints adopted the diet for 2 weeks . The ITIS diet turned out to be not too much of a stretch for Southern California RA patients interested in dietary complementary and alternative medicine. Many had already adopted some elements of the anti-inflammatory diet. Dietary adherence in the study was good, as monitored in food logs and by mass spectrometry metabolic profiling of fecal and plasma samples.

Eleven patients were categorized as responders to the anti-inflammatory diet as defined by at least a 50% improvement in pain scores from baseline to 2 weeks; six patients were nonresponders. In the overall study population, mean pain scores on a 0-10 visual analog scale improved from 3.9 to 2.45. Scores on the Clinical Disease Activity Index (CDAI) also improved significantly on the ITIS diet, from 29 to 12.7, reported Dr. Coras, a rheumatologist at the University of California, San Diego.

The mechanisms for the clinical improvement on the diet are under study. Significant differences in the gut microbiome and metabolome were seen between the responders and nonresponders. For example, Mollicutes were increased and Coriobacteriales decreased in clinical responders versus nonresponders. A significant increase in circulating levels of anti-inflammatory oxylipins was also seen in responders. Longer-term controlled studies of the ITIS diet are planned.

Biqi is big in China, gaining ground in the U.S.

Ayurvedic medicine in India and Chinese traditional herbal medicine have richly documented 4,500-year histories.

“It’s so common in my neck of the woods, where there are large Asian communities, for Chinese or Korean or Japanese or Indian medicines to be combined with our medicines. And if you don’t ask about them, you’re never going to find out what these patients are taking,” Dr. Troum said.

If they’re taking Biqi capsules, readily available on the Internet, be advised that there is randomized trial evidence to show that they’re using an efficacious and safe herbal medicine for RA. In China, the combination of Biqi capsules and a conventional disease-modifying antirheumatic drug such as methotrexate is now widely used for treatment of RA. And at the 2019 ACR annual meeting, Runyue Huang, MD, of Guangzhou University of Chinese Medicine, presented the results of a 24-week, randomized, multicenter, open-label clinical trial in which 70 RA patients were assigned to methotrexate plus a 1.2-g Biqi capsule twice daily or to methotrexate plus leflunomide (Arava) at 20 mg/day. The primary outcome – achievement of a 20% improvement in the ACR criteria, or ACR20 response, at week 24 – was achieved in 77% of the Biqi group, not significantly different from the 83% rate in the comparator group. However, the Biqi plus methotrexate group had significantly fewer adverse events and the combination was better tolerated than was leflunomide plus methotrexate.

In addition, a systematic review of earlier clinical trials concluded that Biqi in combination with methotrexate was more effective and had fewer adverse events than methotrexate alone.

“Biqi capsule with methotrexate appears to be a promising combination for RA if you can rest assured that what’s found in the Biqi capsule is exactly what they say. And that’s the main issue: You don’t really know what you’re getting unless it’s in a trial,” Dr. Troum said.

American RA patients embrace turmeric

Turmeric has played a prominent role in Ayurvedic medicine for millenia. The most medicinally important component of turmeric root is curcumin, which has potent anti-inflammatory and antioxidant properties. Americans with RA have gotten on the bandwagon, as demonstrated in a survey of 291 patients with RA or psoriatic arthritis presented at ACR 2020 by investigators from the University of Central Florida, Orlando.

Children who have higher levels of sun exposure appear to have a substantially lower risk of developing pediatric multiple sclerosis (MS) than children who are less exposed to the sun, research shows. The use of sunscreen does not appear to affect the risk.

“This is the first study, as far as we are aware, to investigate the effect of sun exposure in pediatric MS,” first author Prince Sebastian, of the ANU Medical School, Australian National University, Canberra, said during a presentation at the meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis.

“In order to reduce the incidence of MS, parents should be encouraged to allow their children to spend at least 30 minutes outdoors in the sun every day, while using adequate sun protection,” Mr. Sebastian said.

“This is especially important for children with a family history of MS,” he said. As the findings show, “you can use adequate sun protection and still get the benefit of sun exposure in terms of MS risk reduction.”

Low sun exposure, exposure to ultraviolet light, and vitamin D have been well established as modifiable risk factors for MS in adults. However, research is lacking on the effect of these factors upon patients younger than 18 years who have pediatric MS, a less common form of the disease. Pediatric MS constitutes about 5% of all MS cases.

To investigate the issue, Mr. Sebastian and colleagues evaluated data on 332 patients with pediatric MS who were between the ages of 4 and 22 years. The patients were enrolled at 16 MS centers around the United States. They were compared by sex and age with 534 control persons aged 3-22 years who did not have MS.

For the patients with MS, the median disease duration was 7.3 months, and 63% were female. The median age of the patients was 15.9 years.

Compared with those who did not have MS, patients with MS were significantly less likely to have been exposed to cigarette smoke (17.8% vs. 14.2%). They were significantly more likely to be overweight (23.8% vs. 14.2%), and the median anti-VCA level was higher (3.7 vs. 2.2).

Those who were exposed to the sun during the most recent summer for a duration of 30 minutes to 1 hour daily, as determined on the basis of self-report or parent report, had a 2.6-fold reduced risk of having MS, compared with those who spent less than 30 minutes outdoors daily (odds ratio, 0.39; P < .05), after adjusting for age, sex, birth season, the child’s skin color, the mother’s education, smoke exposure, being overweight, and Epstein-Barr virus infection.

Sun exposure for 1-2 hours daily was associated with a 7.4-fold reduced risk for MS, compared with exposure of 30 minutes or less (OR, 0.13; P < .001).

The odds were similar for those with 2-3 hours of sun exposure (OR, 0.21; P < .001) and for those with more than 3 hours of daily exposure (OR, 0.14; P < .001), versus less than 30 minutes.

Mr. Sebastian and his team also assessed the role of summer ambient levels of UV light and whether such exposure conferred a similar degree of protection. The risk for MS was lower among those who were exposed to higher summer ambient UV levels than among those exposed to lower levels (OR, 0.80; P = .046).

He noted, “Based on the results, individuals residing in Florida (28° N) would have 20% lower odds of MS, compared with an individual residing in New York (40° N).”

Interestingly, median rates of the use of sun protection were similar for the participants with MS and those without MS (OR, 0.95), suggesting that the use of sunscreen did not reduce the protective effect of sun exposure.

“We predicted that greater use of protection would limit effective sun exposure and would therefore increase MS risk,” Mr. Sebastian said, “but we don’t see that, and it’s probably because someone who uses sun protection likely gets more sun exposure anyway.”

“Our results suggest that you can use adequate sun protection and still get most of the benefit in terms of MS prevention, which is quite encouraging,” he added.

For those with MS, median serum 25(OH)D levels were higher (27.7 ng/mL vs. 23.7 ng/mL; P < .001), but Mr. Sebastian noted that this difference was likely attributable to the use of vitamin D supplementation after an MS diagnosis. An important limitation of the study was a lack of data on supplementation.
 

Stronger effect of frequent sun protection

Previous studies have shown a link between sun exposure and MS. A study published in 2018 compared 2,251 patients with MS with 4,028 control persons who did not have MS. The participants were in Canada, Italy, and Norway.

In that study, for most of the patients with MS, the age of onset was older than 18 years. In that study, there was a nearly 50% increased risk among those with the lowest degree of summer sun exposure in comparison with those who had the highest level of exposure (risk ratio, 1.47).

Contrary to the current study, that study did show an effect of the use of sun protection – those with the lowest degree of sun exposure during summer and winter and the highest use of sun protection had the highest risk for MS. They had a 76% increased risk, compared with those who had the highest degree of sun exposure and the least use of sun protection (RR, 1.76).

Sandra Magalhaes, PhD, of the University of New Brunswick, Fredericton, Canada, who was first author on that study, noted that the new study of pediatric MS adds valuable evidence on the issue.

“This study is important, as it adds to the etiological literature on MS implicating relevance of sun exposure,” Dr. Magalhaes said.

“We have a number of studies that have demonstrated an important effect of reduced levels of sun exposure and increased risk of MS. However, these studies focus on adult-onset MS populations; rather, the new study adds to the existing literature, as it also implicates sun exposure in etiology of pediatric-onset MS,” she said.

Notably, their previous work, unlike the current study, showed that, among those who experienced low levels of sun exposure, the risk for MS was higher for those who used sunscreen frequently.

“Overall, in their limited time outdoors, use of sunscreen may further increase risk of MS, which makes sense, since limited time outdoors in less sun, adding sun protection means [exposure to] even less sun.”

The findings of both studies support the bulk of research indicating that sun exposure is beneficial with regard to MS.

“There is a need for promoting balanced safe sun practices to reduce disease burden, especially in countries and cultures where children spend a lot of time indoors,” Dr. Magalhaes said. “Sun exposure has a number of important physiological roles, including vitamin D synthesis but also immune system functioning.”

Mr. Sebastian and Dr. Magalhaes have disclosed no relevant financial relationships.

However, these studies focus on adult-onset MS populations; rather, the new study adds to the existing literature, as it also implicates sun exposure in etiology of pediatric-onset MS,” she said.

Notably, their previous work, unlike the current study, showed that, among those who experienced low levels of sun exposure, the risk for MS was higher for those who used sunscreen frequently.

“Overall, in their limited time outdoors, use of sunscreen may further increase risk of MS, which makes sense, since limited time outdoors in less sun, adding sun protection means [exposure to] even less sun.”

The findings of both studies support the bulk of research indicating that sun exposure is beneficial with regard to MS.

“There is a need for promoting balanced safe sun practices to reduce disease burden, especially in countries and cultures where children spend a lot of time indoors,” Dr. Magalhaes said. “Sun exposure has a number of important physiological roles, including vitamin D synthesis but also immune system functioning.”

Mr. Sebastian and Dr. Magalhaes have disclosed no relevant financial relationships.

Pregnant patients with COVID-19 infections were more likely to experience severe disease if they had preexisting comorbidities, such as chronic hypertension, asthma, or pregestational diabetes, according to findings from a new study presented at the meeting sponsored by the Society for Maternal-Fetal Medicine.

The study included outcomes for the largest multistate cohort of pregnant patients with COVID-19 outside of what the Centers for Disease Control and Prevention is tracking. Its findings also mirrored those of a multicenter, retrospective study in Washington state, published in the American Journal of Obstetrics & Gynecology. That study also found that pregnant patients hospitalized for COVID-19 were more likely to have comorbidities, and both studies found an increased likelihood of preterm birth among pregnant patients with severe or critical disease.
 

Disease severity linked to risk of perinatal complications

In the abstract presented at the SMFM meeting, more severe disease was associated with older age and a higher median body mass index, as seen in the general population, but the researchers found no differences in disease severity occurred by race or ethnicity, Torri D. Metz, MD, of the Eunice Kennedy Shriver National Institute of Child Health and Human Development Maternal-Fetal Medicine Units Network, told attendees of the conference. The researchers also found that perinatal complications were more prevalent in those with severe or critical COVID-19 disease but not in those with mild or moderate disease. Vertical COVID-19 transmission from mother to child was rare.

The observational study included all patients who had a singleton pregnancy, had a positive SARS-CoV-2 test, and delivered between March 1 and July 31, 2020, at one of the 33 U.S. hospitals in the NICHD Maternal-Fetal Medicine Units Network, spread across 14 states. The researchers used electronic medical records to determine incidence of cesarean delivery, postpartum hemorrhage, hypertensive disorders of pregnancy, preterm birth (less than 37 weeks), maternal death, infant death, and positive infant COVID-19 test. They tracked mothers through 6 weeks post partum and newborns through delivery hospitalization.

Of 1,291 patients in the cohort, 1,219 received their first positive COVID-19 test during pregnancy. The others tested positive while in the hospital for delivery or within a month and a half after discharge. Limiting their analysis to those who developed COVID-19 while pregnant prior to delivery, nearly half (47%) were asymptomatic.

The disease was mild in 27%, moderate in 14%, severe in 8%, and critical in 4%. The researchers used the National Institutes of Health classifications for severity and included deaths in the critical group. The most common symptom was a cough, reported by a third of the patients (34%). Four of six maternal deaths that occurred were caused by COVID-19.

Compared with an average age of 28 in those without symptoms, the mean age was 29 in those with mild/moderate disease and 30 in those with severe/critical disease (P = .006). Similarly, the mean BMI was 28.3 in asymptomatic patients, 29 in those with mild/moderate disease, and 32.3 in those with severe/critical disease (P < .001). Despite a diverse cohort – 53% Hispanic, 23% Black, and 15% White – the researches found no racial/ethnic trends in disease severity.

Patients who had asthma, chronic obstructive pulmonary disorder, pregestational diabetes, chronic hypertension, chronic liver disease, or a seizure disorder were all significantly more likely to have critical/severe disease than mild/moderate disease, and more likely to have mild/moderate disease than asymptomatic (P values ranged from < .001 to .02).

The mothers with critical or severe illness were 1.6 times more likely to have cesarean births and to have hypertensive disorders of pregnancy, and they were twice as likely to have postpartum hemorrhage (P < .001; P = .007). Those with mild or moderate disease, however, had no increased risks for perinatal complications over asymptomatic patients.

Critical or severe illness was also associated with more than triple the risk of preterm birth (adjusted risk ratio, 3.6; P < .001). Newborns of mothers with critical or severe illness also had three times greater risk of neonatal ICU admission (ARR, 3.1; P <. 001) and weighed an average 385 g less than newborns of asymptomatic mothers. COVID-19 rate among infants was only 1% during delivery hospitalization.

Since the study cutoff was July 30 and COVID infections only became prevalent in March, the researchers were unable to evaluate women for outcomes resulting from COVID infections in early pregnancy, such as congenital anomalies or early miscarriage, Dr. Metz said. In addition, since many of the sites are urban centers, the data may not be generalizable to rural areas.

Peter S. Bernstein, MD, MPH, of Montefiore Medical Center, New York, asked whether the increased cesarean deliveries and preterm births in the group of women with severe disease were caused by usual obstetric causes or the treatment of COVID-19 infection. Dr. Metz said the vast majority of preterm deliveries were indicated, but only a small proportion were induced for COVID-19 alone. “A lot had hypertensive disorders of pregnancies or PPROM, so it’s partly driven by the infection itself but also partly driven by some of those perinatal complications,” she said.
 

Similar findings in Washington

In the Washington study, among 240 pregnant patients with confirmed COVID-19 infection between March 1 and July 30, 2020, 1 in 11 developed severe or critical disease, and 1 in 10 were hospitalized. The pregnant patients had more than triple the risk of hospitalization compared with adults of similar ages in the general population (10% vs. 2.8%; rate ratio, 3.5). Similar to the multistate NICHD study, women were more likely to be hospitalized if they had asthma, hypertension, type 2 diabetes, autoimmune disease, or class III obesity.

Three mothers died of COVID-19, resulting in a case fatality rate 13.6 times greater than nonpregnant patients with COVID-19 in the general population. The absolute difference in the rate was 1.2%. As seen in the NICHD study, preterm birth was more common in mothers with severe or critical COVID-19. Nearly half (45.4%) of mothers with severe or critical COVID-19 delivered preterm compared to 5.2% in those with mild COVID-19 (P < .001).

“Our finding that deaths in pregnant patients contributed disproportionately to deaths from COVID-19 among 20- to 39-year-olds in Washington state is similar to what was observed during the influenza A virus H1N1 2009 pandemic,” Erica M. Lokken, PhD, MS, of the departments of global health and ob.gyn. at the University of Washington, Seattle, and colleagues wrote in the Washington study. But they noted that it took 8 months into the pandemic before pregnant patients were identified as a high-risk group for COVID-19.

“Given the similarity in clinical course between COVID-19 and IAV H1N1 2009 with an increased risk for mortality during pregnancy and the postpartum period, we strongly recommend that pregnant patients should be considered a high-risk population to novel highly pathogenic respiratory viruses until proven otherwise by population-based studies with good ascertainment of pregnancy status,” they wrote.

Judette Louis, MD, MPH, associate professor of ob.gyn. and department chair at the University of South Florida, Tampa, said in an interview that the findings in these studies were fairly expected, but it’s important to have data from such a large cohort as the one presented at SMFM.

“It confirmed that those who had severe disease were more likely to have chronic medical conditions, mirroring what we saw in the general population who isn’t pregnant,” Dr. Louis said. “I thought this was very crucial because as pregnant women are trying to decide whether they should get the COVID vaccine, this provides support to say that if you’re pregnant, you’re more likely to have severe disease [if you have] other chronic medical conditions.”

The findings also confirm the importance of pregnant people taking precautions to avoid infection.

“Even though these individuals are, as a group, in an age cohort that mostly has asymptomatic disease, for some of them, it results in severe disease and even maternal death,” she said. “They should still take it seriously if they’re pregnant.”

The SMFM abstract study was funded by the NICHD. The Washington study was funded by the University of Washington Population Health Initiative, the National Institutes of Health, and philanthropic gift funds. One coauthor of the Washington study is on a Pfizer and GlaxoSmithKline advisory board for immunizations. No other authors or individuals interviewed reported any disclosures.

The first rule about infantile hemangiomas: Make sure they’re actually infantile hemangiomas, a pediatric dermatologist urged colleagues. Then watch patients closely, refer to specialists when appropriate, and consider propranolol in complicated or high-risk cases, Andrea L. Zaenglein, MD, said at MedscapeLive’s Women’s & Pediatric Dermatology Seminar.

“In my career as a pediatric dermatologist, propranolol has been a life changer for us more than any other medicine,” said Dr. Zaenglein, professor of dermatology and pediatric dermatology, Penn State University, Hershey.

Before the point where propranolol is prescribed, confirm the diagnosis and use the correct terminology, she advised. It’s still appropriate to use the International Society for the Study of Vascular Anomalies (ISSVA) vascular lesion classification system released in 1982. “For most people, it serves the purpose well,” she said. Another option is an updated and more complex classification system from 2015.

Dr. Zaenglein highlighted two studies – one published in 2011 and the other published in 2020 – that revealed high levels of misclassification of vascular malformations in research reports. The earlier study found that 21% of patients with misclassified lesions were mistreated, compared with none of those who were classified using ISSVA terminology.

“I cannot stress [proper classification] enough when you’re dealing with babies and children with vascular lesions. If not sure, be vague. Say ‘a vascular tumor’ or a ‘vascular malformation.’ But only reserve ‘infantile hemangioma’ for that very diagnosis,” she said.

As Dr. Zaenglein noted, infantile hemangiomas affect 5%-10% of 1-year-olds, of whom 20% have multiple lesions. They’re more common in females by a 3-to-1 margin, and also seen more in premature infants, and in cases of multiple births, higher maternal age, and low birth weight.

The pathogenesis of these lesions is unclear, she said, although there are hints about genetic components and tissue hypoxia, among other possible causes. “Importantly, you get 80% of the growth by 3-4 months of age. Then it’ll slow in its growth and kind of slowly go away over time, but it’s not linear regression. It’s more that you get more improvement up front, usually until about 5, and then you can get some continued gradual evolution up until about 7 or 10 years of age.”

Complications can include ulceration, infection and – in rare cases – hemorrhage and high-output cardiac failure, she said. “Knowing which ones are at high risk for complications is important, and also there are systemic associations that we have to be mindful of. We also want to think about aesthetic outcomes as well when we talk about management of infantile hemangiomas.”

High-risk infantile hemangiomas include those with the following features:

• Extensive facial involvement. Dr. Zaenglein highlighted a case of a 2-year-old baby with a large, bulky hemangioma that distorted facial features around the eye. “This would be a medical emergency” requiring immediate evaluation and treatment, she said.
• Periocular involvement. Refer to ophthalmology, she recommended. “Even smaller hemangiomas can cause refractive errors or amblyopia, and oftentimes need to be treated with either systemic or topical therapy depending on the size and extent,” she said.
• PHACE syndrome (Posterior fossa malformations, hemangiomas, arterial anomalies, coarctation of the aorta and cardiac defects, eye abnormalities). “Propranolol has been safely used in PHACE, but every patient is different,” she said. “You need to make sure to do a good risk assessment before starting because if they have narrowed blood flow or limited blood flow, there is a question of whether there is potential risk for stroke if you drop a baby’s blood pressure. Make sure that the vasculature is evaluated before started on propranolol. Also, there are recent reports of risk of long-term risk of stroke with PHACE syndrome as patients are getting into their adulthood.”
• Beard distribution. Be aware of possible airway involvement that can be revealed by biphasic stridor. In those cases, immediate treatment – perhaps even with tracheostomy – is needed to avoid mortality, she said.
• Multiple sites: Patients with five or more hemangiomas may have liver involvement, she said, and should undergo hepatic evaluation. Consider evaluating if this is suspected, even if the number of hemangiomas is under five, she said.
• Perineal/lumbosacral involvement: A third of these cases are associated with spinal dysraphism. Refer to neurosurgery, she recommended.

Dr. Zaenglein highlighted a report on the use of propranolol published in 2008 and noted that clinical practice guidelines for managing infantile hemangiomas published in 2019 are also helpful.

Flat hemangiomas, meanwhile, can benefit from timolol maleate 0.5% solution or gel-forming solution – 1 drop twice daily or 2 drops once daily, she said. This treatment should be avoided in thick hemangiomas, she said.

• Periocular involvement. Refer to ophthalmology, she recommended. “Even smaller hemangiomas can cause refractive errors or amblyopia, and oftentimes need to be treated with either systemic or topical therapy depending on the size and extent,” she said.
• PHACE syndrome (Posterior fossa malformations, hemangiomas, arterial anomalies, coarctation of the aorta and cardiac defects, eye abnormalities). “Propranolol has been safely used in PHACE, but every patient is different,” she said. “You need to make sure to do a good risk assessment before starting because if they have narrowed blood flow or limited blood flow, there is a question of whether there is potential risk for stroke if you drop a baby’s blood pressure. Make sure that the vasculature is evaluated before started on propranolol. Also, there are recent reports of risk of long-term risk of stroke with PHACE syndrome as patients are getting into their adulthood.”
• Beard distribution. Be aware of possible airway involvement that can be revealed by biphasic stridor. In those cases, immediate treatment – perhaps even with tracheostomy – is needed to avoid mortality, she said.
• Multiple sites: Patients with five or more hemangiomas may have liver involvement, she said, and should undergo hepatic evaluation. Consider evaluating if this is suspected, even if the number of hemangiomas is under five, she said.
• Perineal/lumbosacral involvement: A third of these cases are associated with spinal dysraphism. Refer to neurosurgery, she recommended.

Dr. Zaenglein highlighted a report on the use of propranolol published in 2008 and noted that clinical practice guidelines for managing infantile hemangiomas published in 2019 are also helpful.

Flat hemangiomas, meanwhile, can benefit from timolol maleate 0.5% solution or gel-forming solution – 1 drop twice daily or 2 drops once daily, she said. This treatment should be avoided in thick hemangiomas, she said.

The first rule about infantile hemangiomas: Make sure they’re actually infantile hemangiomas, a pediatric dermatologist urged colleagues. Then watch patients closely, refer to specialists when appropriate, and consider propranolol in complicated or high-risk cases, Andrea L. Zaenglein, MD, said at MedscapeLive’s Women’s & Pediatric Dermatology Seminar.

“In my career as a pediatric dermatologist, propranolol has been a life changer for us more than any other medicine,” said Dr. Zaenglein, professor of dermatology and pediatric dermatology, Penn State University, Hershey.

Before the point where propranolol is prescribed, confirm the diagnosis and use the correct terminology, she advised. It’s still appropriate to use the International Society for the Study of Vascular Anomalies (ISSVA) vascular lesion classification system released in 1982. “For most people, it serves the purpose well,” she said. Another option is an updated and more complex classification system from 2015.

Dr. Zaenglein highlighted two studies – one published in 2011 and the other published in 2020 – that revealed high levels of misclassification of vascular malformations in research reports. The earlier study found that 21% of patients with misclassified lesions were mistreated, compared with none of those who were classified using ISSVA terminology.

“I cannot stress [proper classification] enough when you’re dealing with babies and children with vascular lesions. If not sure, be vague. Say ‘a vascular tumor’ or a ‘vascular malformation.’ But only reserve ‘infantile hemangioma’ for that very diagnosis,” she said.

As Dr. Zaenglein noted, infantile hemangiomas affect 5%-10% of 1-year-olds, of whom 20% have multiple lesions. They’re more common in females by a 3-to-1 margin, and also seen more in premature infants, and in cases of multiple births, higher maternal age, and low birth weight.

The pathogenesis of these lesions is unclear, she said, although there are hints about genetic components and tissue hypoxia, among other possible causes. “Importantly, you get 80% of the growth by 3-4 months of age. Then it’ll slow in its growth and kind of slowly go away over time, but it’s not linear regression. It’s more that you get more improvement up front, usually until about 5, and then you can get some continued gradual evolution up until about 7 or 10 years of age.”

Complications can include ulceration, infection and – in rare cases – hemorrhage and high-output cardiac failure, she said. “Knowing which ones are at high risk for complications is important, and also there are systemic associations that we have to be mindful of. We also want to think about aesthetic outcomes as well when we talk about management of infantile hemangiomas.”

Only about 30% or fewer of patients with psoriatic arthritis (PsA) on therapy achieve disease remission by any definition. One reason for this may be inadequate attention to common comorbid conditions, Alexis Ogdie, MD, MSCE, declared at the 2021 Rheumatology Winter Clinical Symposium.

“I believe that addressing off-target aspects of disease is really important to improving the patient experience of their disease. We might need to target these directly in order to improve outcomes,” said Dr. Ogdie, a rheumatologist and epidemiologist at the University of Pennsylvania, Philadelphia, who coauthored the current American College of Rheumatology/National Psoriasis Foundation PsA guidelines.

Since rheumatologists are by now well informed about the increased cardiovascular risk associated with PsA, she focused on two common comorbidities that get less attention, both of which are associated with worse clinical outcomes in PsA: obesity and mental health issues.
 

Anxiety and depression

Dr. Ogdie was first author of a large, population-based, longitudinal cohort study of cause-specific mortality in 8,706 U.K. patients with PsA, 41,752 with RA, and more than 81,000 controls. Particularly striking was the finding of elevated mortality because of suicide in the rheumatic disease patients: a 203% increased risk in the PsA population, compared with the general population, and a 147% greater risk in patients with RA.

Overall, 30%-40% of PsA patients have comorbid depression and/or anxiety.

“That’s pretty striking. It’s also true for rheumatoid arthritis and axial spondyloarthritis. And if you’re depressed, you’re much less likely to respond to therapy in the way that we are measuring response to therapy,” Dr. Ogdie said.

Her approach to screening for depression and anxiety in her PsA patients, and indeed in all her other patients, is to begin by normalizing the topic, explaining to them that these affective disorders are common among patients with these disorders. She lets her patients know they can talk to her about it. And she informs them that, while effective treatment of their rheumatic disease may improve their depression or anxiety, managing those is also important for improving their disease. Additionally, understanding whether depression is present is important prior to prescribing certain medications. Apremilast (Otezla), for example, can worsen preexisting depression.

“Ask about signs and symptoms of depression,” Dr. Ogdie urged her colleagues. “I do this at every single visit in my review of symptoms. This is one I don’t skip. I ask: ‘Do you have any symptoms of depression or anxiety?’ ”

Structured evidence-based screening tools, many of which are well suited for completion during a patient’s preappointment check-in survey, include the Patient Health Questionnaire–2, the PHQ-9, the Patient-Reported Outcomes Measure Information System–10, PROMIS–Depression, and Routine Assessment of Patient Index Data 3.

“I also really like the PROMIS-29. It covers many domains of interest: depression and anxiety, sleep, fatigue, pain, physical function. It gives a lot of information about what’s going on in a patient’s life right now,” according to the rheumatologist.

The main thing is to regularly screen for anxiety and depression and then refer symptomatic patients for further assessment and treatment. This is not something that all rheumatologists have been trained to do.

Obesity

Dr. Ogdie was lead author of a national CORRONA Registry study which concluded that obese patients with PsA were only half as likely to achieve remission on a tumor necrosis factor (TNF) inhibitor, compared with nonobese patients. She believes the same holds true for all other types of therapy: Across the board, obesity is associated with a poor response. And obesity is much more common in PsA patients than the general population in every age group. Moreover, obesity is associated with risk factors for cardiovascular disease and is associated with fatty liver disease, two other major comorbid conditions in the PsA population.

The CORRONA Registry findings are supportive of an earlier Italian prospective, observational study of 135 obese and an equal number of normal-weight PsA patients, all of whom started on a TNF inhibitor and were followed for 24 months. In a multivariate-adjusted analysis, obesity was independently associated with a 390% higher risk of not achieving minimal disease activity.

The same Italian group subsequently conducted a prospective dietary intervention study in 138 overweight or obese patients with PsA starting anti-TNF therapy. A total of 59% of participants randomized to either of the two dietary interventions experienced at least a 5% weight loss at 6 months. The key study finding: Compared with the subjects with less than 5% weight loss, those with 5%-10% weight loss were 275% more likely to achieve minimal disease activity at 6 months, and in those with greater than 10% weight loss the likelihood of attaining minimal disease activity increased by 567%.

“We’re talking about a disease where treatments tested in clinical trials have odds ratios in the 1.2 range, compared with other therapies, so this is a really striking difference,” she observed.

Several studies have demonstrated that obesity in psoriasis patients is a risk factor for developing PsA. Recently, U.K. investigators took things a step further, reporting in a huge observational study that obese or overweight psoriasis patients who reduced their body mass index over a 10-year period had a corresponding reduction in the risk of developing PsA, compared with overweight or obese psoriasis patients whose BMI remained steady over the same period.

What’s needed now is access to programs to help patients with PsA lose weight. Health insurers are often unwilling to provide coverage. “We have a really tough time getting the patients in to see a nutritionist unless they’re willing to pay out of pocket,” Dr. Ogdie said.

Physical activity is an important element in successful weight loss. It also is recommended in practice guidelines for patients with inflammatory arthritis because of its salutary effects on disease activity scores, pain and stiffness, sleep, and quality of life. But a recent survey conducted by Dr. Ogdie and coworkers concluded that patients with PsA and other forms of inflammatory arthritis don’t receive much exercise guidance from their rheumatologists. About 60% of subjects were inactive. Those who were physically active typically engaged in aerobic exercise but were much less likely to do the other guideline-recommended forms of exercise, namely flexibility, balance, and resistance training. The patients’ report of low engagement of their physicians “suggests an opportunity for more prescriptive exercise discussions,” according to the investigators.

Diabetes, a critical risk factor for cardiovascular disease, occurs at an increased incidence in PsA. This was demonstrated in a U.K. cohort study coauthored by Dr. Ogdie. The study, which included nearly 4,200 individuals with PsA, concluded that they had a 43% greater incidence of diabetes than the general population in an analysis adjusted for body mass index, smoking, alcohol use, and demographics.

New-onset diabetes can be readily picked up by rheumatologists based upon the laboratory work they often order at patient office visits, or during their review of symptoms, she noted, and added that the U.S. Preventive Services Task Force recommends ordering a hemoglobin A1c test every 3 years.

Dr. Ogdie reported receiving research grants and/or consulting fees from numerous pharmaceutical companies. Her research is also funded by the National Institute of Arthritis and Musculoskeletal and Skin Diseases, the Rheumatology Research Foundation, and the National Psoriasis Foundation.

Novel therapies have transformed the treatment of hemophilia in recent decades, but these new approaches also raise new challenges for clinicians who monitor joint health in persons with hemophilia, a specialist said.

“Patient-reported outcomes should be combined with other, more objective outcome measures for joint health monitoring, and joint ultrasound is a promising tool for objective joint health monitoring, although, due to its relatively recent introduction in clinical practice, we lack objective data and standardization,” said Roberta Gualtierotti, MD, PhD, from the Università Degli Studi of Milan.

She reviewed the challenges and approaches to monitoring joint health in persons with hemophilia during the annual congress of the European Association for Haemophilia and Allied Disorders.

Over the last decades the target of hemophilia treatment has shifted from prolonging survival to improving joint health and quality of life, and care has improved with the introduction of novel therapies such as extended half-life replacement products, nonreplacement therapies, and gene therapy, she noted.

However, “due to different pharmacodynamics and pharmacokinetics profiles, the currently available therapies cannot be compared to each other on several levels,” Dr. Gualtierotti said.

Laboratory monitoring of replacement therapies with standard coagulation assays may be unreliable, and depending on the mechanism of action and type of administration of nonreplacement agents, patients may experience breakthrough bleeding, especially after traumatic injury, she said.

Until the specific noncoagulatory effects of factor VIII on bone and joint health is better understood, close monitoring of patients will be required, she added.
 

Outcome measures

Subjective measures of joint health include patient-reported bleeding rates and health-related quality of life. These are practical for home management, but patients may not be able to distinguish symptoms of acute joint bleeding from chronic arthritis pain, with the potential for either under- or overtreatment, and subjective reporting is likely to miss subclinical bleeding that can occur even when patients are on prophylaxis.

Health-related quality of life tools, whether generic or specific for hemophilia, are not sensitive to small improvements, and they are not always used in routine clinical practice.

Objective measures include physical examination with scoring according to the World Federation of Hemophilia (Gilbert Scale) score or Hemophilia Joint Health Score, but these measures have limited ability to identify early or subclinical joint abnormalities.

“Therefore, joint physical examination on its own is not a sufficient measure of treatment efficacy, and it should be used in combination with other tools more objective, such as imaging,” Dr. Gualtierotti said.
 

Get the picture?

Imaging with x-rays, MRI, and, recently in some centers, point-of-care ultrasound can provide clinicians with important real-time information about the joint stability and health.

Point-of-care ultrasound in particular offers promise as a practical tool, with no ionizing radiation and high sensitivity for synovial hyperplasia subclinical joint effusion. It’s relatively inexpensive, can be used to image multiple joints, and allows for ease of follow-up, she said. The technique requires specialized training, however, and there is a lack of prospective data about its utility in hemophilia.

Various ultrasound scoring systems have been proposed, and home-based ultrasound is currently being explored in several clinical trials, Dr. Gualtierotti noted.

Other avenues for remote joint health monitoring under consideration are serum or synovial biomarkers for joint bleeding and arthropathy that could be employed at bedside or at home, smartphone apps for breakthrough bleeding and patient-reported outcomes, and sensors for detecting abnormalities in gait that may signal joint dysfunction, she said.
 

Best practice

In the question-and-answer session following the talk, Fernando Zikan, MD, from the Federal University of Rio de Janeiro noted that, “in underdeveloped countries, we still find it very difficult to guide good practices for joint health control by the patient and family members. Which strategy do you think is fundamental for the patient to feel safe to notice changes in his body?”

“It would be useful to educate patients to come to the center whenever the patient has trauma and whenever an increase in his physical activity occurs. If this is far, a bedside ultrasound evaluation by the general practitioner could help avoid joint damage. Finally, a correct rehabilitation is fundamental,” Dr. Gualtierotti replied.

Asked by several others whether she used ultrasound in her daily practice, Dr. Gualtierotti said that “we use joint ultrasound in our clinical practice in the regular annual check-up examination and whenever the patient suspects and reports hemarthrosis.”

Dr. Gualtierotti reported participation in advisory boards for Biomarin, Pfizer, Bayer, and Takeda, and in educational seminars sponsored by Pfizer, Sobi, and Roche. She has received support for congress travel and/or attendance by Bayer and Pfizer. Dr. Zikan reported no relevant disclosures.

Subjective measures of joint health include patient-reported bleeding rates and health-related quality of life. These are practical for home management, but patients may not be able to distinguish symptoms of acute joint bleeding from chronic arthritis pain, with the potential for either under- or overtreatment, and subjective reporting is likely to miss subclinical bleeding that can occur even when patients are on prophylaxis.

Health-related quality of life tools, whether generic or specific for hemophilia, are not sensitive to small improvements, and they are not always used in routine clinical practice.

Objective measures include physical examination with scoring according to the World Federation of Hemophilia (Gilbert Scale) score or Hemophilia Joint Health Score, but these measures have limited ability to identify early or subclinical joint abnormalities.

“Therefore, joint physical examination on its own is not a sufficient measure of treatment efficacy, and it should be used in combination with other tools more objective, such as imaging,” Dr. Gualtierotti said.
 

Get the picture?

Imaging with x-rays, MRI, and, recently in some centers, point-of-care ultrasound can provide clinicians with important real-time information about the joint stability and health.

Point-of-care ultrasound in particular offers promise as a practical tool, with no ionizing radiation and high sensitivity for synovial hyperplasia subclinical joint effusion. It’s relatively inexpensive, can be used to image multiple joints, and allows for ease of follow-up, she said. The technique requires specialized training, however, and there is a lack of prospective data about its utility in hemophilia.

Various ultrasound scoring systems have been proposed, and home-based ultrasound is currently being explored in several clinical trials, Dr. Gualtierotti noted.

Other avenues for remote joint health monitoring under consideration are serum or synovial biomarkers for joint bleeding and arthropathy that could be employed at bedside or at home, smartphone apps for breakthrough bleeding and patient-reported outcomes, and sensors for detecting abnormalities in gait that may signal joint dysfunction, she said.
 

Best practice

In the question-and-answer session following the talk, Fernando Zikan, MD, from the Federal University of Rio de Janeiro noted that, “in underdeveloped countries, we still find it very difficult to guide good practices for joint health control by the patient and family members. Which strategy do you think is fundamental for the patient to feel safe to notice changes in his body?”

“It would be useful to educate patients to come to the center whenever the patient has trauma and whenever an increase in his physical activity occurs. If this is far, a bedside ultrasound evaluation by the general practitioner could help avoid joint damage. Finally, a correct rehabilitation is fundamental,” Dr. Gualtierotti replied.

Asked by several others whether she used ultrasound in her daily practice, Dr. Gualtierotti said that “we use joint ultrasound in our clinical practice in the regular annual check-up examination and whenever the patient suspects and reports hemarthrosis.”

Dr. Gualtierotti reported participation in advisory boards for Biomarin, Pfizer, Bayer, and Takeda, and in educational seminars sponsored by Pfizer, Sobi, and Roche. She has received support for congress travel and/or attendance by Bayer and Pfizer. Dr. Zikan reported no relevant disclosures.

Novel therapies have transformed the treatment of hemophilia in recent decades, but these new approaches also raise new challenges for clinicians who monitor joint health in persons with hemophilia, a specialist said.

“Patient-reported outcomes should be combined with other, more objective outcome measures for joint health monitoring, and joint ultrasound is a promising tool for objective joint health monitoring, although, due to its relatively recent introduction in clinical practice, we lack objective data and standardization,” said Roberta Gualtierotti, MD, PhD, from the Università Degli Studi of Milan.

She reviewed the challenges and approaches to monitoring joint health in persons with hemophilia during the annual congress of the European Association for Haemophilia and Allied Disorders.

Over the last decades the target of hemophilia treatment has shifted from prolonging survival to improving joint health and quality of life, and care has improved with the introduction of novel therapies such as extended half-life replacement products, nonreplacement therapies, and gene therapy, she noted.

However, “due to different pharmacodynamics and pharmacokinetics profiles, the currently available therapies cannot be compared to each other on several levels,” Dr. Gualtierotti said.

Laboratory monitoring of replacement therapies with standard coagulation assays may be unreliable, and depending on the mechanism of action and type of administration of nonreplacement agents, patients may experience breakthrough bleeding, especially after traumatic injury, she said.

Until the specific noncoagulatory effects of factor VIII on bone and joint health is better understood, close monitoring of patients will be required, she added.

Liposomal doxorubicin (Dox) plus pomalidomide (Pom) was safe and active in heavily pretreated patients with Kaposi sarcoma, according to results from a phase 1/2 trial.

“The results of our phase 1/2 study suggest pomalidomide and liposomal doxorubicin is safe with evidence of activity among patients with Kaposi sarcoma,” said investigator Ramya Ramaswami, MBBS, MPH, of the HIV & AIDS malignancy branch at the National Cancer Institute. The results were presented at the Conference on Retroviruses and Opportunistic Infections.

The researchers evaluated the safety and tolerability of Pom/Dox in two groups of patients with Kaposi sarcoma: group 1 included patients with Kaposi sarcoma alone and group 2 included patients with Kaposi sarcoma–associated herpesvirus and concurrent multicentric Castleman disease (KSHV-MCD) and KSHV inflammatory cytokine syndrome (KICS).

“Kaposi sarcoma can be challenging to treat when it co-occurs with KSHV-MCD or KICS, resulting in high mortality rates,” Dr. Ramaswami explained.

Study participants received IV liposomal Dox at 20 mg/m² on day 1 of a 28-day cycle, in addition to oral Pom once daily on days 1-21 at three escalating dose levels (2 mg, 3 mg, or 4 mg, respectively) using a standard 3 + 3 design until plateau of response, progression, dose-limiting toxicities (DLTs) or patient preference. Some eligibility criteria differed between groups 1 and 2. Participants in group 1 were required to be on antiretroviral therapy for at least 1 month and had a performance status of 2 or less, while those in group 2 had a performance status of 3 or less and could be antiretroviral therapy naive.

All participants received oral aspirin thromboprophylaxis (81 mg daily) and could have received prior Kaposi sarcoma therapy.

With respect to outcomes, Kaposi sarcoma responses were assessed using the modified AIDS Clinical Trial Group criteria and KICS and KSHV-MCD responses were evaluated using an NCI clinical benefit criteria.
 

Results

Overall, 34 cisgender men were enrolled in the study: 21 (62%) in group 1 and 13 (38%) in group 2. All participants had severe (T1) Kaposi sarcoma; 32 (94%) participants were HIV-infected and 22 (65%) had prior chemotherapy for Kaposi sarcoma.

While the HIV viral load was largely controlled in both groups, the CD4 count differed, with median CD4 counts of 286 and 92 cells/mcL in groups 1 and 2, respectively.

With respect to safety, no DLTs were observed in group 1. As a result, 12 participants were treated at the maximum tolerated dose (MTD) of 4 mg of Pom. However, two DLTs (grade 3 rash and pharyngeal edema) were observed in group 2 at the 3 mg dose level.

A median of six cycles were administered for all participants and the most common grade 3/4 toxicity was neutropenia; nine patients with grade 3 neutropenia required dose reduction and three patients had febrile neutropenia requiring hospitalization. Other Pom-related adverse events were rash, constipation, and fatigue.

Among evaluable participants receiving two or more cycles, 17 (81%) patients in group 1 had a response (95% confidence interval, 58-95%; 16 partial response and 1 complete response) and 5 (50%) patients in group 2 had a response (95% CI, 19-81%; 4 PR and 1 CR).

“Our waterfall plots indicated that the vast majority of patients in group 1 had a positive change in nodular lesions at baseline,” Dr. Ramaswami said. “Participants in group 2 showed some decrease in nodular lesions, but this was usually temporary.”

Among seven participants with KICS responses, four participants (57%) experienced a CR or PR in symptoms and lab abnormalities associated with KICS; three of six participants (50%) with KSHV-MCD responses experienced a PR as per response criteria.

“While activity was noted, the combination was less well tolerated in patients with Kaposi sarcoma and concurrent KSHV-MCD or KICS,” Dr. Ramaswami said.

During a live discussion, Ronald T. Mitsuyasu, MD, of the University of California, Los Angeles, asked Dr. Ramaswami about the use of liposomal doxorubicin alone in patients with Kaposi sarcoma and concurrent KSHV-MCD or KICS.

While there is currently no data on the use of doxorubicin alone in this population, Dr. Ramaswami noted that she was more confident administering Pom/Dox combination therapy for these patients.

Dr. Ramaswami disclosed financial relationships with the National Cancer Institute, Celgene/Bristol-Myers Squibb, EMD Serono, Merck, CTI Biopharma, and Janssen. The study was funded by a cooperative research and drug development agreement between the National Cancer Institute and Celgene/BMS, EMD Serono, Merck, CTI Biopharma, and Janssen.

Erythropoietin (EPO), shown in early studies to potentially provide neuroprotection for patients with optic neuritis, failed to provide any significant neuroprotection in comparison with placebo in a phase 3 randomized controlled trial.

“EPO conveyed neither functional nor structural neuroprotection in the visual pathways after optic neuritis as a clinically isolated syndrome,” said first author Wolf A. Lagreze, MD, of the University of Freiburg (Germany), in presenting the results at the meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis.

There are currently no treatments that provide neuroprotection for patients with optic neuritis, which can result in the degeneration of retinal ganglion cells, the axons of which form the optic nerve.

Although methylprednisolone, the standard treatment, can be of benefit, it has no effect in preventing neurodegeneration or subsequent vision impairment.

Importantly, optic neuritis, which can be a first sign of multiple sclerosis (MS), is considered an ideal model for an acute inflammatory attack on the nervous system and resulting neurodegeneration. Therefore, any treatment that provides neuroprotection for patients with optic neuritis could have potentially exciting broader implications.
 

The TONE trial

Preclinical studies have shown that EPO provides a small, potential degree of neuroprotection. To further evaluate EPO in this setting, Dr. Lagreze and colleagues conducted the TONE trial (Treatment of Optic Neuritis With Erythropoietin) in Germany between 2014 and 2017, in which they enrolled 108 patients with optic neuritis.

Inclusion criteria were having only unilateral optic neuritis as a clinically isolated syndrome that presented within 10 days of the first symptoms and having moderate to severe loss of visual acuity.

Persons with known MS were excluded; however, patients who were diagnosed with MS at the beginning of the study during the workup evaluation were included. Hence, about 20% of patients did have newly diagnosed MS, Dr. Lagreze noted.

The participants were randomly assigned in double-blind 1:1 ratio to receive treatment with either 33,000 IU EPO or placebo intravenously for 3 days as an adjunct to high-dose intravenous methylprednisolone (1,000 mg/day).

The final analysis included 52 patients who received EPO and 51 patients who received placebo. There were no significant differences between the groups in the first primary outcome of retinal nerve fiber layer atrophy, assessed with optic coherence tomography at week 26 (P = .76).

Likewise, no significant difference between groups was observed in the second primary outcome of low-contrast visual acuity at week 26, assessed using the 2.5% Sloan chart score of the affected eye (P = .38).

In addition, there were no significant differences between the groups in the rates of optic neuritis relapse.

In terms of safety measures, one patient in the EPO group developed sinus venous thrombosis, which was treated with anticoagulants and resolved without complications.
 

Reduced conversion to MS?

Interestingly, after 6 months, significantly fewer patients in the EPO arm (36%) had converted from clinically isolated syndrome to MS, compared with 57% in the placebo arm (P = .032). The difference became apparent as early as week 4.

Although those findings suggest that EPO provided some neuroprotection, there are notable caveats, Philippe Albrecht, MD, of the department of neurology at the University Hospital Dusseldorf (Germany), and a coauthor on the study, said.

“The significant separation of EPO and placebo group regarding MS conversion was observed very early on in the course and did not change thereafter,” Dr. Albrecht noted.

“One would expect a true disease-modifying effect of EPO on MS conversion to take longer to develop, and this early separation may very well have been due to an imbalance in the treatment groups, [for example] regarding MRI imaging findings such as gadolinium enhancement at baseline,” he said.

Dr. Lagreze said that it was a surprise to see no benefit from the drug, and a closer look at certain subgroups may still be worthwhile. Factors that could have a bearing on results include a shorter time interval for inclusion, having no concomitant use of steroids, and longer duration of treatment with EPO.

“If I could do the study again, I would do the treatment for longer than 3 days – that was based on experiences in previous EPO trials,” he said. “I would also love to do the trial without the concomitant methylprednisolone, but that is not possible from an ethical point of view.”
 

Trial nevertheless important

Commenting on the study, E. Anne Yeh, MD, of the division of neurology at the Hospital for Sick Children, Toronto, agreed that a challenge in evaluating therapies for optic neuritis is the potential for confounding from existing therapies that patients need to take.

“This agent could not be evaluated alone for its protective effect in comparison to no treatment at all,” she said.

In addition, improved metrics for gauging outcomes are needed to better determine the true effects, she added.

“The development of newer vision-related outcome metrics is important for future studies, and many are hard at work on both structural and functional metrics that may help us to understand the benefits of any protective therapies in a more nuanced manner than we are currently able to,” she said.

However, results of any kind – negative or positive – are valuable in improving understanding, Dr. Yeh underscored.

“Negative results can be disappointing in any trial, especially one in which alternative therapeutic pathways are being sought,” Dr. Yeh said. “I want to emphasize, however, that the fact that we are even considering and completing trials in this area is important.”

Dr. Yeh noted that she is currently involved in a trial that is evaluating the diabetes drug metformin for its remyelinating potential. “We hope to have some pilot data on MS in a few years,” she said.

Dr. Lagreze, Dr. Albrecht, and Dr. Yeh have disclosed no relevant financial relationships.

Preclinical studies have shown that EPO provides a small, potential degree of neuroprotection. To further evaluate EPO in this setting, Dr. Lagreze and colleagues conducted the TONE trial (Treatment of Optic Neuritis With Erythropoietin) in Germany between 2014 and 2017, in which they enrolled 108 patients with optic neuritis.

Inclusion criteria were having only unilateral optic neuritis as a clinically isolated syndrome that presented within 10 days of the first symptoms and having moderate to severe loss of visual acuity.

Persons with known MS were excluded; however, patients who were diagnosed with MS at the beginning of the study during the workup evaluation were included. Hence, about 20% of patients did have newly diagnosed MS, Dr. Lagreze noted.

The participants were randomly assigned in double-blind 1:1 ratio to receive treatment with either 33,000 IU EPO or placebo intravenously for 3 days as an adjunct to high-dose intravenous methylprednisolone (1,000 mg/day).

The final analysis included 52 patients who received EPO and 51 patients who received placebo. There were no significant differences between the groups in the first primary outcome of retinal nerve fiber layer atrophy, assessed with optic coherence tomography at week 26 (P = .76).

Likewise, no significant difference between groups was observed in the second primary outcome of low-contrast visual acuity at week 26, assessed using the 2.5% Sloan chart score of the affected eye (P = .38).

In addition, there were no significant differences between the groups in the rates of optic neuritis relapse.

In terms of safety measures, one patient in the EPO group developed sinus venous thrombosis, which was treated with anticoagulants and resolved without complications.
 

Reduced conversion to MS?

Interestingly, after 6 months, significantly fewer patients in the EPO arm (36%) had converted from clinically isolated syndrome to MS, compared with 57% in the placebo arm (P = .032). The difference became apparent as early as week 4.

Although those findings suggest that EPO provided some neuroprotection, there are notable caveats, Philippe Albrecht, MD, of the department of neurology at the University Hospital Dusseldorf (Germany), and a coauthor on the study, said.

“The significant separation of EPO and placebo group regarding MS conversion was observed very early on in the course and did not change thereafter,” Dr. Albrecht noted.

“One would expect a true disease-modifying effect of EPO on MS conversion to take longer to develop, and this early separation may very well have been due to an imbalance in the treatment groups, [for example] regarding MRI imaging findings such as gadolinium enhancement at baseline,” he said.

Dr. Lagreze said that it was a surprise to see no benefit from the drug, and a closer look at certain subgroups may still be worthwhile. Factors that could have a bearing on results include a shorter time interval for inclusion, having no concomitant use of steroids, and longer duration of treatment with EPO.

“If I could do the study again, I would do the treatment for longer than 3 days – that was based on experiences in previous EPO trials,” he said. “I would also love to do the trial without the concomitant methylprednisolone, but that is not possible from an ethical point of view.”
 

Trial nevertheless important

Commenting on the study, E. Anne Yeh, MD, of the division of neurology at the Hospital for Sick Children, Toronto, agreed that a challenge in evaluating therapies for optic neuritis is the potential for confounding from existing therapies that patients need to take.

“This agent could not be evaluated alone for its protective effect in comparison to no treatment at all,” she said.

In addition, improved metrics for gauging outcomes are needed to better determine the true effects, she added.

“The development of newer vision-related outcome metrics is important for future studies, and many are hard at work on both structural and functional metrics that may help us to understand the benefits of any protective therapies in a more nuanced manner than we are currently able to,” she said.

However, results of any kind – negative or positive – are valuable in improving understanding, Dr. Yeh underscored.

“Negative results can be disappointing in any trial, especially one in which alternative therapeutic pathways are being sought,” Dr. Yeh said. “I want to emphasize, however, that the fact that we are even considering and completing trials in this area is important.”

Dr. Yeh noted that she is currently involved in a trial that is evaluating the diabetes drug metformin for its remyelinating potential. “We hope to have some pilot data on MS in a few years,” she said.

Dr. Lagreze, Dr. Albrecht, and Dr. Yeh have disclosed no relevant financial relationships.

Elevated vaginal pH at the time of cervical intraepithelial neoplasia 2 diagnosis may be a useful marker of CIN 2 persistence/progression, as well as the rate of persistence/progression in HIV-positive women, new research suggests.

“We analyzed data from the Women’s Interagency HIV Study [WIHS], an observational, longitudinal cohort of women with and without HIV to determine factors that may influence CIN 2 natural history,” said Kate Michel, PhD, MPH, of Georgetown University, Washington. She presented the results at the Conference on Retroviruses and Opportunistic Infections.

As previous data have shown a high incidence of CIN 2 progression among women with HIV, the researchers evaluated the role of human papillomavirus (HPV) type, local immune response, and markers of the cervicovaginal microbiome on the risk of CIN 2 persistence/progression.

Within the cohort, follow-up visits occur every 6 months, and clinical data is collected via questionnaires, physical and gynecologic exams, and biological samples. As no specific treatment is offered in the WIHS, treatment for cervical abnormalities is abstracted from medical records.

In the present study, Dr. Michel and colleagues selected up to four banked cervicovaginal lavage (CVL) samples per woman, with the first sample selected 6-12 months prior to CIN 2 diagnosis, the second at CIN 2 diagnosis, the third between CIN 2 diagnosis and outcome, and the fourth at the outcome visit.

The investigators performed HPV typing and muiltiplex immune mediator testing on each CVL sample. Lab results from WIHS core testing were also extracted, including plasma CD4+ T-cell count and HIV viral load, as well as vaginal pH and Nugent’s score.

Study outcomes included persistence/progression and regression, defined as a subsequent CIN 2 or CIN 3 diagnosis and subsequent CIN 1 or normal diagnosis, respectively. Logistic regression models were used to determine CIN 2 regression versus persistence/progression.
 

Results

A total of 337 samples were obtained and 94 women were included in the analysis. Key demographic and behavioral factor were similar at CIN 2 diagnosis.

The majority of participants were African American (53.2%) and on antiretroviral therapy (66.0%). The most prevalent high-risk types were HPV-58 (18.4%) and HPV-16 (17.5%).

After a median 12.5 years of follow-up, 33 participants (35.1%) with incident CIN 2 had a subsequent CIN 2/CIN 3 diagnosis and those who regressed had a higher CD4 T-cell count at CIN 2 diagnosis (P = .02).

Each subsequent high-risk HPV type identified at the pre–CIN 2 visit was associated with higher odds of CIN2 persistence/progression (odds ratio, 2.27; 95% confidence interval, 1.15-4.50).

Bacterial vaginosis (adjusted OR, 5.08; 95% CI, 1.30-19.94) and vaginal pH (aOR, 2.27; 95% CI, 1.15-4.50) at the CIN 2 diagnosis visit were each associated with increased odds of CIN 2 persistence/progression.

Vaginal pH greater than 4.5 at CIN 2 diagnosis was also associated with unadjusted time to CIN 2 persistence/progression (log rank P = .002) and an increased rate of CIN 2 persistence/progression (adjusted hazard ratio, 3.37; 95% CI, 1.26-8.99).

Furthermore, among participants who did not receive CIN 2 treatment, vaginal pH remained associated with greater odds of CIN 2 persistence/progression (OR, 2.46; 95% CI, 1.19-5.13). Cervicovaginal immune mediator levels were not associated with CIN 2 persistence/progression.

“The most striking finding from this work was that vaginal pH was associated with higher odds of, quicker time to, and increased hazard of CIN 2 persistence/progression,” Dr. Michel said. “We postulate this effect is mediated by the cervical microbiome, but more work is needed to establish the exact mechanism.”

“It would be interesting to test whether this association might be explained by different vaginal cleaning techniques, such as douching,” said moderator Ronald T. Mitsuyasu, MD, of the University of California, Los Angeles.

“We’re currently working on an analysis of cervicovaginal bacterial species to explore the microbiome in more detail,” Dr. Michel concluded.

Dr. Michel disclosed no conflicts of interest. The study was supported by multiple sources, including the National Institute of Allergy and Infectious Diseases, the National Cancer Institute, and the Georgetown-Howard Universities Center for Clinical and Translational Science.
