Tirofiban does not improve outcomes of endovascular treatment in stroke
, new data suggest.
In a randomized, phase 3 trial of more than 900 patients with acute ischemic stroke who underwent endovascular treatment, the median Modified Rankin Scale (mRS) score at 90 days was 3 both in patients who received tirofiban and those who received placebo.
“There was treatment-effect modification by stroke etiology, where patients with large-artery atherosclerosis [LAA] seemed to benefit from the treatment,” said investigator Raul Nogueira, MD, director of the University of Pittsburgh Medical Center Stroke Institute, during his presentation. “Tirofiban may improve endovascular treatment outcomes in LAA strokes. This obviously requires further investigation in future trials to confirm these findings.”
Results of the RESCUE BT trial were presented at the hybrid International Stroke Conference (ISC) 2022, which was held in New Orleans, Louisiana, and online.
Multicenter trial
Endovascular treatment greatly increases the rate of reperfusion and improves functional outcomes in patients with large-vessel occlusion stroke, the researchers note. But mechanical thrombectomy devices may injure the vessel wall, which can lead to clot formation and vessel reocclusion.
Platelet inhibition is a potential tactic for improving outcomes in this setting. Tirofiban, a glycoprotein IIb/IIIa receptor inhibitor, is a reversible antiplatelet drug with a rapid onset of action and a short half-life. The drug’s safety and efficacy in acute coronary syndrome are well established. There has been little evidence to date, however, on whether tirofiban improves outcomes among patients with large-vessel occlusion stroke.
The investigators conducted the Endovascular Treatment With Versus Without Tirofiban for Stroke Patients With Large Vessel Occlusion (RESCUE BT) trial to evaluate the safety and efficacy of IV tirofiban therapy before endovascular treatment in patients with large-vessel occlusion stroke. They recruited consecutive patients at 55 thrombectomy-capable hospitals in China.
Eligible patients were aged 18 years or older and presented within 24 hours of the time they were last seen when well. Baseline National Institutes of Health Stroke Scale (NIHSS) score was required to be 30 or lower, and all patients were required to have plans to undergo endovascular treatment. Eligible patients also had a baseline Alberta Stroke Program Early CT Score of 6 or greater.
Patients were randomized in groups of equal size to placebo or tirofiban and stratified by NIHSS score and occlusion site. Tirofiban was administered in a 10-mcg/kg bolus followed by continuous infusion (0.15 mcg/kg per min) for 24 hours. All patients underwent rapid endovascular treatment.
At the 20th hour after treatment initiation, antiplatelets were administered orally. IV study drug was stopped at the 24th hour.
The study’s primary endpoint was disability level, as measured by overall distribution of the 90-day mRS score. The primary safety endpoints were symptomatic intracranial hemorrhage (ICH) at 48 hours and mortality at 90 days.
Increased ICH risk
The investigators screened 1,970 patients and enrolled 950 into their study. The population’s median age was 67 years, and 58.8% of participants were men. In all, 463 participants were randomly assigned to tirofiban, and 485 to placebo. Two patients withdrew consent, and none were lost to follow-up.
Baseline characteristics were well balanced in both groups. One difference, however, was that large-vessel occlusion was less prevalent in the tirofiban group (42.6%) than in the control group (49.1%).
The primary endpoint did not differ between treatment groups. The adjusted common odds ratio was 1.09 (P = .46). “There is perhaps a sign that there is maybe a favorable effect of tirofiban,” said Dr. Nogueira. “However, this did not reach statistical significance.”
The rates of symptomatic ICH and mortality at 90 days did not differ significantly between groups. There was a trend toward a higher rate of symptomatic ICH in the tirofiban group, however. Moreover, the rate of any ICH was 34.9% in the tirofiban group and 28.0% in the control group (P = .02).
In prespecified subgroup analysis, the researchers found that, among patients with large-vessel occlusion, the adjusted common odds ratio was 1.43 favoring tirofiban treatment. No other subgroups showed significant differences.
“In the intention-to-treat analysis, tirofiban did not improve clinical outcomes in the overall study population,” said Dr. Nogueira. “It did increase the rate of any ICH and potentially increased the rate of symptomatic ICH as well.”
The ongoing RESCUE BT2 trial is examining the safety and efficacy of tirofiban in patients with acute ischemic stroke with non–large-vessel occlusion. As of Jan. 20, 781 patients had been assigned randomly to treatment, said Dr. Nogueira.
Patient selection crucial
Louise McCullough, MD, PhD, professor and chair of neurology at the University of Texas Health Science Center at Houston, said that the study was well designed.
“The concern with any kind of platelet therapy or adjunctive therapy is hemorrhage,” said Dr. McCullough, who was not involved in the research. The results in the overall population support this concern.
The location of the trial sites may have influenced the results. “It was a multicenter trial, but it was predominantly done in Asia, and we know that there are higher levels of intracranial atherosclerosis in that population,” said Dr. McCullough.
The results indicate a potential benefit of tirofiban in patients with large-vessel occlusion, yet this finding raises practical questions. “It’s often difficult to know if these patients have atherosclerosis until you’re actually in the vessel,” said Dr. McCullough.
The findings may not have immediate practical implications. “I don’t think that in routine clinical practice it’s something that we would offer until we can decide how safe it is,” said Dr. McCullough. The question will be how to select the populations in whom the drug will have the most efficacy.
The study was funded by the National Natural Science Foundation of China, Army Medical University, and Lunan Pharmaceutical Group, the manufacturer of tirofiban. Dr. Nogueira reported holding stock in Brainomix, Viz-AI, Corindus Vascular Robotics, Vesalio, Viz-AI, and Ceretrieve. He has received research support from Corindus Vascular Robotics. Dr. Nogueira reported other financial relationships related to Stryker Neurovascular, Medtronic, Cerenovus, and Phenox. Dr. McCullough has disclosed no relevant financial relationships.

Treatment for BV, trichomoniasis approved for adolescents
The antimicrobial agent, marketed as Solosec, was first approved in 2017 as a treatment for BV in adult women. In 2021, it was approved for the treatment of trichomoniasis in adult men and women.
Lupin Pharmaceuticals, which manufactures the drug, announced the expanded approval for adolescents in a news release.
The medication is meant to be taken as a single dose. It comes in a packet that should be sprinkled onto applesauce, yogurt, or pudding and consumed without chewing or crunching.
The treatment option may help “address gaps in care related to adherence,” said Tom Merriam, an executive director with Lupin.
Bacterial vaginosis is a common vaginal infection. Trichomoniasis is the most common nonviral, curable STI in the United States. Sexual partners of patients with trichomoniasis can be treated at the same time.
Vulvovaginal candidiasis is one of the possible side effects of secnidazole treatment, the drug’s label notes.

Psilocybin’s antidepressant effects rapid, durable
The substantial antidepressant effects of psilocybin-assisted therapy may be durable up to at least 1 year in some patients with major depressive disorder (MDD), new research indicates.
, report researchers with the Center for Psychedelic and Consciousness Research at Johns Hopkins University School of Medicine, Baltimore.
“We have not yet collected formal data past 1 year in our sample, [but] some participants in our study have stayed in touch and report continued improvements in mood,” study investigator Natalie Gukasyan, MD, told this news organization.
“A previous study of psilocybin-assisted therapy in patients with cancer-related depression and anxiety symptoms found that improvements in mood and well-being may persist up to 4.5 years following treatment,” Dr. Gukasyan noted.
The study was published online Feb. 15 in the Journal of Psychopharmacology.
Enduring benefit
Preliminary data suggest that psilocybin-assisted treatment produces substantial and rapid antidepressant effects in patients with MDD, but the durability of the effects are unclear.
Investigators examined the efficacy and safety of psilocybin through 12 months in 24 adults who met criteria for a moderate to severe episode of MDD as defined by a score of 17 or greater on the GRID-Hamilton Depression Rating Scale (GRID-HAMD) assessed by blinded clinician raters.
Following 6-8 hours of preparatory meetings, participants received two doses of psilocybin at 20 mg/70 kg and 30 mg/70 kg spaced roughly 2 weeks apart. Psilocybin was administered in a comfortable room under supervision following established safety guidelines.
Depression, as measured by GRID-HAMD, decreased substantially after treatment and remained low through 12 months post-treatment, the investigators report.
For most participants, GRID-HAMD scores decreased from 22.8 at baseline to 8.7 at 1 week, 8.9 at 4 weeks, 9.3 at 3 months, 7 at 6 months, and 7.7 at 12 months after treatment.
“The effect size at 12 months was very large (Cohen d = 2.4). Likewise, high and stable rates of response and remission occurred throughout the follow-up period (75% response and 58% remission at 12 months),” the investigators note.
Two patient-rated measures of depression – the Quick Inventory of Depressive Symptoms (QIDS) and the Beck Depression Inventory II (BDI-II) – showed similar “large magnitude and stable” antidepressant effects on mean scores and on response and remission rates, they add.
Response and remission rates at 12 months on the QIDS were 79% and 67%, respectively, and 83% and 75%, respectively, on the BDI-II.
“Psilocybin not only produces significant and immediate effects, it also has a long duration, which suggests that it may be a uniquely useful new treatment for depression,” study investigator Roland Griffiths, PhD, founding director of the Center for Psychedelic and Consciousness Research, says in a statement.
“Compared to standard antidepressants, which must be taken for long stretches of time, psilocybin has the potential to enduringly relieve the symptoms of depression with one or two treatments,” Dr. Griffiths adds.
Better than ketamine?
There were no serious adverse events judged to be related to psilocybin during long-term follow-up. Depression symptoms were not significantly exacerbated in any participant, and there was no reported use of psilocybin or other psychedelic drug use during the follow-up period.
The finding that two doses of psilocybin provides antidepressant effects that last through at least 12 months is well beyond the duration of effects reported to date with ketamine, the investigators write.
“In general, treatment with ketamine requires a greater number of drug administrations, and it may be more challenging to get durable therapeutic efficacy without repeated dosing. The longer-term risks of repeated ketamine use are not well characterized,” Dr. Gukasyan told this news organization.
She noted that psilocybin and related compounds are still not available for clinical use under the controlled substances act.
“Some clinics are currently offering ketamine, or ketamine-assisted therapy in a manner that resembles the treatment approach used with psilocybin, but there is less high-quality research to support that practice,” she said.
The study was funded in part by a crowdsourced campaign organized by Tim Ferriss and by grants from the Riverstyx Foundation and Dave Morin. Other support was provided by a grant from the National Institutes of Health and the Center for Psychedelic and Consciousness Research. Dr. Gukasyan is an investigator for a multisite trial of psilocybin-assisted therapy for major depressive disorder sponsored by Usona Institute.

“In general, treatment with ketamine requires a greater number of drug administrations, and it may be more challenging to get durable therapeutic efficacy without repeated dosing. The longer-term risks of repeated ketamine use are not well characterized,” Dr. Gukasyan told this news organization.
She noted that psilocybin and related compounds are still not available for clinical use under the controlled substances act.
“Some clinics are currently offering ketamine, or ketamine-assisted therapy in a manner that resembles the treatment approach used with psilocybin, but there is less high-quality research to support that practice,” she said.
The study was funded in part by a crowdsourced campaign organized by Tim Ferriss and by grants from the Riverstyx Foundation and Dave Morin. Other support was provided by a grant from the National Institutes of Health and the Center for Psychedelic and Consciousness Research. Dr. Gukasyan is an investigator for a multisite trial of psilocybin-assisted therapy for major depressive disorder sponsored by Usona Institute.

Top strategies for preventing tardive dyskinesia
LAS VEGAS –
“But this does not seem to always be the case, because there is still a risk of TD, and we need to monitor for it,” Dr. Correll, professor of psychiatry and molecular medicine at The Donald and Barbara Zucker School of Medicine at Hofstra/Northwell, New York, said during an annual psychopharmacology update held by the Nevada Psychiatric Association. “It is important to minimize the risk of TD by educating patients and caregivers about the risks of and alternatives to antipsychotic medication and early signs of TD.”
First described in 1957, TD is characterized by involuntary repetitive but irregular movements, mostly in the oral, lingual, and buccal regions – such as tongue protruding, puckering, chewing, and grimacing. Less often, there are movements in the hands, legs, feet, and torso. Symptoms can include mannerisms, stereotypies, tics, myoclonus, dystonias, tremor, and akathisia. “TD can be severe, persistent, and have medical and psychosocial consequences,” Dr. Correll said. “It can occur in untreated patients, but treatment with dopamine blocking agents – antipsychotics and metoclopramide – increases risk for TD.”
Differential diagnoses to consider include morbus Huntington, benign familial Chorea, and Sydenham’s Chorea. Less frequent causes of TD include metabolic conditions such as uremia, hyponatremia, hypernatremia, hypoparathyroidism, and hyperparathyroidism. “Those would need to be ruled out during the physical exam,” he said. There can also be inflammatory causes of TD such as herpes simplex virus, varicella, measles, mumps, and rubella.
A standard measure for TD diagnosis is the Abnormal Involuntary Movement Scale (AIMS), an observer-rated 12-item anchored scale that takes 5-10 minutes to administer. However, the AIMS on its own does not diagnose TD. In 1982, researchers developed three diagnostic criteria for TD: At least 3 months of cumulative antipsychotic drug exposure; presence of at least moderate abnormal involuntary movements in one or more body area(s) or mild movements in two or more body areas, and absence of other conditions that might produce involuntary movements (Arch Gen Psychiatry 1982;39:486-7).
The impact of TD on everyday functioning depends on anatomic location as well as severity, Dr. Correll continued. The condition can cause impairments to speech, verbal communication, dentition, temporomandibular joint pain/myalgia, swallowing difficulties, and fine motor skills including instrumental activities of daily living and written communication. Truncal and lower extremity TD can affect gait, posture and postural stability, strength, power flexibility, physical capacity, and one’s ability to exercise. “There are also psychological impairments,” he said. “Patients can develop different awareness so they become self-conscious; there can be cognitive abnormalities, and they can become more anxious or [have an] increased sense of paranoia, isolation, stigma, social and/or educational/vocational impairment.”
According to research by Dr. Correll and colleagues, unmodifiable patient-related risk factors for TD include older age, female sex, and being of white or African descent (J Neurol Sci 2018 June 15; 389:21-7). Unmodifiable illness-related risk factors include longer duration of illness, intellectual disability and brain damage, negative symptoms in schizophrenia, mood disorders, cognitive symptoms in mood disorders, and gene polymorphisms involving antipsychotic metabolism and dopamine functioning. Modifiable comorbidity-related factors include diabetes, smoking, and alcohol/substance abuse, while modifiable treatment-related factors include dopamine receptor blockers, higher cumulative and current antipsychotic dose or plasma levels, early parkinsonian side effects, treatment-emergent akathisia, and anticholinergic co-treatment. In a meta-analysis of 41 studies that aimed to determine the prevalence of TD, the mean age of the 11,493 patients was 43, 66% were male, and 77% had schizophrenia spectrum disorders (J Clin Psychiatry. 2017 Mar;78[3]:e264-78). The global mean TD prevalence was 25%, but the rates were lower with patients on current treatment with second-generation antipsychotics compared with those on first-generation antipsychotics (21% vs. 30%, respectively).
According to Dr. Correll, strategies for preventing TD include confirming and documenting the indication for dopamine antagonist antipsychotic medications, using conservative maintenance doses, and considering the use of SGAs, especially in those at high risk for EPS (extrapyramidal symptoms). “Don’t go too high [with the dose],” he said. “Stay below the EPS threshold. Inform patients and caregivers of the risk of TD and assess for incipient signs regularly using the AIMS.”
Treatment options include discontinuing antipsychotics, adjusting their dose, or switching patients from a first-generation antipsychotic to a second-generation antipsychotic. Supplementation with antioxidants/radical scavengers such as vitamin E, vitamin B6, ginkgo biloba, and fish oil “can be tried, but have limited evidence, as is the case for melatonin.” Other options include clonazepam, amantadine, donepezil, and tetrabenazine, a reversible and specific inhibitor of vesicular monoamine transporter-2 (VMAT-2), a transporter that packages neurotransmitters (preferentially dopamine) into vesicles for release into the synapse and was approved in 2008 as an orphan drug for the treatment of choreiform movements associated with Huntington’s disease. “Neurologists have using tetrabenazine off-label for TD, but in schizophrenia and other psychiatric care, we rarely use it because it has to be given three times a day and it has a black box warning for depression and suicidality,” he said.
Dr. Correll noted that the Food and Drug Administration approval of two more recent VMAT-2 inhibitors – deutetrabenazine (Austedo) and valbenazine (Ingrezza) – provides an evidence-based care option for the effective management of TD. Deutetrabenazine requires titration over several weeks and twice-daily dosing, while valbenazine can reach the maximum dose by the beginning of week 2 and is dosed once daily. Deutetrabenazine should be taken with food, which is not required valbenazine.
“Both VMAT-2 inhibitors are generally well tolerated and have a positive benefit-risk ratio,” he said. “Both are recommended by the APA guidelines as the preferred and only evidence-based treatment for TD.”
Dr. Correll reported that he has received honoraria from and has been an advisory board member for numerous pharmaceutical companies. He has also received grant support from Janssen, the National Institute of Mental Health, the Patient Centered Outcomes Research Institute, Takeda, and the Thrasher Foundation.

REPORTING FROM NPA 2022
Childhood-onset insomnia persists into adolescence and adulthood
Childhood-onset insomnia is a chronic problem in 43% of children, based on 15-year follow-up data from approximately 500 individuals.
Difficulty initiating or maintaining sleep (DIMS) is the most frequently reported insomnia symptom in children and teens, but longitudinal data on the trajectory of insomnia symptoms from childhood into adulthood are limited, Julio Fernandez-Mendoza, PhD, of Penn State University, Hershey, and colleagues wrote.
Previous studies have shown varying results, notably on the effect of objective short sleep duration (OSSD), they said. The extent to which the effect of OSSD on insomnia trajectories, and whether OSSD affects the development of insomnia in the transition to adulthood remains uncertain.
In a study published in Pediatrics, the researchers reviewed data from 502 children who enrolled at age 5-12 years between 2000 and 2005. The participants underwent laboratory polysomnography visits at baseline; 421 had a second laboratory visit between 2010 and 2013 (median age, 16 years), and 502 completed a structured self-reported survey between 2018 and 2021 at a median age of 24 years. At the first visit, 118 children met criteria for insomnia, defined as parent reports of often/moderate or very often/severe DIMS and/or use of over-the-counter or prescription sleep medications for DIMS. At the second visit, 120 children met the definition for insomnia.
Among children with insomnia symptoms at baseline, 53.7% had persistence of insomnia symptoms in adolescence and 61.9% had symptoms in young adulthood; 46.3% and 38.1% remitted at these times.
Among children with insomnia symptoms at adolescence, 57.5% and 42.5% had persistence and remittance, respectively, in young adulthood.
In children with insomnia at baseline, therefore, the most frequent developmental trajectory was persistence (43.3%) followed by remission (26.9% since childhood and 11.2% since adolescence) and a waxing and waning pattern (18.6%), the researchers said.
Among children with normal sleep at baseline, 69.7% retained normal sleep patterns in adolescence and 63.3% retained normal sleep in young adulthood; 30.3% and 36.7% developed insomnia in adolescence and young adulthood, respectively.
Overall, adult insomnia was reported by 22.0% and 20.8% of individuals with childhood and adolescent insomnia, respectively. In a multivariate analysis, the odds of adult insomnia were 2.6 times and 5.5 times higher among those with histories of short-sleeping in childhood and adolescence, respectively.
“The most common developmental trajectory for insomnia symptoms was that of persistence from childhood through young adulthood,” the researchers wrote in their discussion of the study.
“These 15-year longitudinal findings across three developmental stages indicate that insomnia symptoms should not be expected to developmentally remit in at least 40% of children and that adolescence is a critical developmental period for the adverse prognosis of the insomnia with short sleep duration phenotype,” they emphasized.
The study findings were limited by several factors including the collection of OSSD and other sleep data via a 1-night, 9-hour polysomnography, which might not be representative of habitual sleep at home, the researchers noted. Other limitations include the lack of polysomnography data to accompany the young adult survey and the inability to validate insomnia in young adults via strict diagnostic criteria.
However, the results reveal that the persistence of childhood insomnia is higher than suggested in previous studies, and that these children and adolescents, especially short sleepers, are at significantly increased risk of adult insomnia, the researchers concluded.
“Early sleep interventions are a priority, as clinicians should not expect insomnia symptoms to developmentally remit in a high proportion of children, although objective sleep measures may be indicated in adolescence to identify those with poorer long-term prognosis,” they said.
Pandemic prompts interest in sleep issues
The current study is important at this time because sleep disruptions in children and adolescents have increased over the course of the COVID-19 pandemic, Karalyn Kinsella, MD, a pediatrician in private practice in Cheshire, Conn., said in an interview.
Dr. Kinsella said she was especially surprised to see that adolescent insomnia will most likely not remit in young adulthood, as she had considered it a disorder of adolescence.
The study highlights the need for early intervention to manage insomnia in children. However, there are several barriers to such intervention. “Parents [of young children] are overwhelmed and just need sleep themselves, so they don’t always have the energy to work on good sleep habits in their children,” she said. Improving sleep habits in adolescents requires overcoming the barrier of the young patients’ attitudes. “For adolescents, they need to buy into the change.”
However, the take-home message for clinicians is that it is important to work to overcome these barriers and improve sleep in children and teens, because the longitudinal data suggest that the problem is “likely to persist and unlikely to remit,” for many, she said.
As for additional studies, “I would like to see more research done on neurologic and psychological causes of insomnia,” Dr. Kinsella said.
The study was supported in part by grants from the National Heart, Lung, and Blood Institute; National Institute of Mental Health; and the National Center for Advancing Translational Sciences of the National Institutes of Health. The researchers had no financial conflicts to disclose. Dr. Kinsella had no financial conflicts to disclose and serves on the editorial advisory board of Pediatric News.

Other limitations include the lack of polysomnography data to accompany the young adult survey and the inability to validate insomnia in young adults via strict diagnostic criteria.
However, the results reveal that the persistence of childhood insomnia is higher than suggested in previous studies, and that these children and adolescents, especially short sleepers, are at significantly increased risk of adult insomnia, the researchers concluded.
“Early sleep interventions are a priority, as clinicians should not expect insomnia symptoms to developmentally remit in a high proportion of children, although objective sleep measures may be indicated in adolescence to identify those with poorer long-term prognosis,” they said.
Pandemic prompts interest in sleep issues
The current study is important at this time because sleep disruptions in children and adolescents have increased over the course of the COVID-19 pandemic, Karalyn Kinsella, MD, a pediatrician in private practice in Cheshire, Conn., said in an interview.
Dr. Kinsella said she was especially surprised to see that adolescent insomnia will most likely not remit in young adulthood, as she had considered it a disorder of adolescence.
The study highlights the need for early intervention to manage insomnia in children. However, there are several barriers to such intervention. “Parents [of young children] are overwhelmed and just need sleep themselves, so they don’t always have the energy to work on good sleep habits in their children,” she said. Improving sleep habits in adolescents requires overcoming the barrier of the young patients’ attitudes. “For adolescents, they need to buy into the change.”
However, the take-home message for clinicians is that it is important to work to overcome these barriers and improve sleep in children and teens, because the longitudinal data suggest that the problem is “likely to persist and unlikely to remit,” for many, she said.
As for additional studies, “I would like to see more research done on neurologic and psychological causes of insomnia,” Dr. Kinsella said.
The study was supported in part by grants from the National Heart, Lung, and Blood Institute; National Institute of Mental Health; and the National Center for Advancing Translational Sciences of the National Institutes of Health. The researchers had no financial conflicts to disclose. Dr. Kinsella had no financial conflicts to disclose and serves on the editorial advisory board of Pediatric News.

Urticaria: An elusive disorder with ‘a high unmet need for treatment’
In the clinical experience of Adam Friedman, MD, when patients present with acute urticaria, the culprit is usually food, a drug, or a bug.
But in some cases, the trigger remains elusive. “We don’t always find the source, but don’t beat yourself up about it,” Dr. Friedman, professor and chair of dermatology at George Washington University, Washington, said at the ODAC Dermatology, Aesthetic, and Surgical Conference. “The basic rule is to treat patients to clearance and keep them clear.”
Chronic urticaria is characterized by plaques with a burning/itch sensation that often “move” to different locations on the body over minutes to hours, and they typically last for less than 24 hours. The plaques are often oval, round, or irregular in shape and they typically leave no postinflammatory pigmentary alteration or scarring other than from scratching.
Urticaria affects an estimated 20% of the population, Dr. Friedman said, and is more common in females than males. More than two-thirds of cases are self-limiting but 10% can persist longer than 5 years. Acute episodes are more likely to have an identifiable trigger, while chronic episodes, which last more than six weeks, typically do not. The longer the duration, the lower the chance of identifying the root cause. The foods/food products most commonly affecting children with acute urticaria include milk, egg, peanut, wheat, and soy, while the common culprits in adults are tree nuts, peanuts, and shellfish. Other triggers include the yellow food dye annatto, the red food dye carmine, contact with raw fruits or vegetables, animal saliva, and certain detergents or perfume.
“When you have no idea what the cause is for acute urticaria, I think about viral or bacterial infections, especially in children,” Dr. Friedman said, particularly mycoplasma, adenovirus, enterovirus, rotavirus, respiratory syncytial virus, Epstein-Barr virus, and cytomegalovirus. COVID-19 has also been a new etiologic source for a recent rise in acute urticaria cases.
Other causes include certain medications such as antibiotics, opiates, muscle relaxants, salicylates, and NSAIDs; stinging insects; and exposure to latex products, which can cross react with passion fruit, banana, avocado, chestnut, and kiwi. Alcohol consumption can also trigger urticaria.
“Ask patients if they have joint discomfort or pain,” Dr. Friedman advised, referring to urticaria arthritis syndrome that is typically seen more often in women than in men. “It’s rare but important, because that may distinguish for you what is needed to get those patients under control.”
which spontaneously occurs after an exposure to an external force. “The distinguishing feature here is that it doesn’t last long – 30 minutes or so – and is typically unresponsive to corticosteroids,” Dr. Friedman said. “It comes on quickly but disappears quickly whereas with chronic spontaneous urticaria, someone might be getting those wheals of flare for hours and hours.”
The most common form of physical urticaria is dermatographism, while other examples include physical urticaria resulting from exposure to cholinergic agents, heat, exercise, cold, water, sunlight, and pressure on the skin.
About half of patients with chronic urticaria are disease free within 1 year, but 20% continue to experience episodes for more than 10 years. One study found that patients with chronic spontaneous urticaria who were diagnosed at a younger age trended toward a longer disease course, and rates were higher in women, compared with men. “Perceived stress can make this worse,” Dr. Friedman added.
According to Dr. Friedman, it’s more important to ask patients targeted questions during office visits than it is to do a full workup. “I ask patients to keep a diary, which can help them identify triggers if there are any,” he said. “I also ask them to take a picture of the papules with their smartphone. There can be a genetic association, so it’s important to ask if anyone else in the family has urticaria. No routine lab tests are required unless there’s something in the history that suggests it’s worthwhile. Let the patient guide the diagnostic workup; don’t just order a million tests.”
That said, known comorbidities associated with urticaria include autoimmune disease, atopy, infections, metabolic conditions, and neoplastic disorders. “Biopsies are typically useless because this is an invisible dermatosis,” he said. “They’re useful when it’s urticarial, not urticaria, when you’re trying to figure out what it is.”
According to recently published international guidelines on urticaria, published in September 2021, the recommended first line of treatment for urticaria is with second-generation nonsedating antihistamines such as cetirizine and loratadine, up to four times the recommended dose.
Second-generation derivatives include desloratadine, levocetirizine, and fexofenadine. “I like using fexofenadine in the morning for folks who don’t tolerate cetirizine, then I’ll recommend something a little more sedating at night,” Dr. Friedman said. “We max out [the dose] by week 4. If it works, great. If not, we move on to something else.”
In late 2021, the British Association of Dermatologists also published guidelines on the treatment of chronic urticaria.
As for markers of treatment success, a study of 240 children with chronic spontaneous urticaria found that risk factors for a poor response included longer duration of disease, higher treatment step until initial disease control, and food sensitization.
Vitamin D supplementation may also add some benefit. One study of 42 adults with urticaria found that low and high doses of vitamin D added to antihistamine therapy can boost effectiveness. “This may be because vitamin D could be a marker of severity,” Dr. Friedman said. “The reality is, however, that a lot of patients don’t do well.”
Data from the large, prospective study known as AWARE (A World-Wide Antihistamine-Refractory Chronic Urticaria Patient Evaluation) found that 23% patients treated with nonsedating H1-antihistamines and 42% patients treated with up-dosed nonsedating H1-antihistamines had uncontrolled chronic spontaneous urticaria at month 24.
A second-line treatment option for patients aged 6 and older is the anti-IgE antibody omalizumab, 150-300 mg by subcutaneous injection every 4 weeks. Dr. Friedman typically uses only the 300-mg dose. “You do not need to take pretreatment serum IgE levels,” he said. “The most significant adverse event is anaphylaxis, which only affects 0.2% of patients.”
A third-line option is cyclosporine A. A dose of 3-5mg/kg per day appears to benefit about two-thirds of patients with antihistamine recalcitrant chronic urticaria. “It works fast but you can’t keep patients on it for very long,” he said.
Another third-line option is mycophenolate mofetil, which may work by inhibiting the production of autoantibodies to the high-affinity IgE receptor and/or IgE. “It does work well, especially in conjunction with antihistamines; it’s kind of a softer immunosuppressant,” he said. Methotrexate can also be used as an add-on therapy to H1 antihistamine therapy in difficult-to-treat cases.
“It’s great we have [a Food and Drug Administration]–approved biologic therapy in omalizumab and access to over-the-counter antihistamines, but there is a high unmet need for treatment,” and a need for new therapies, Dr. Friedman said. “Only about 39% achieve symptomatic control with conventional dosing of antihistamines, and 63% of nonresponders achieve symptom control with a fourfold increased dosing of antihistamines.” In addition, about 20% of patients will not respond to either standard or increased doses of antihistamines and are eligible for treatment with omalizumab. However, more than 50% of such patients experience a delay or lack of response to omalizumab. “We need innovation; we need to understand the disease better,” he said.
Dr. Friedman disclosed that he serves as a consultant and/or adviser for Loreal, La Roche Posay, Cerave, Galderma, Aveeno, Microcures, Pfizer, Novartis, Dermira, Brickell Biotech, Incyte, UCB, Janssen, Pfizer, Bristol-Myers Squibb, Almirall, Zylo Therapeutics, Hoth Therapeutics, Corbus, Greenway Therapeutics, TruPotency, and Dermavant.

Mixed results for cardiologists in stroke thrombectomy
Outcomes were mixed among ischemic stroke patients with large vessel occlusion who underwent thrombectomy by an interventional cardiologist as part of a multidisciplinary stroke team, in a single-center, prospective study from Poland.
Results from the 2-year experience show mechanical thrombectomy took longer when carried out by interventional cardiologists than by vascular surgeons and neuroradiologists (120 minutes vs. 105 minutes; P = .020).
The procedures were also less likely to achieve angiographic success, defined as a Thrombolysis in Cerebral Infarction (TICI) scale score of 2b or 3 (55.7% vs. 71.7%; P = .013), reported Krystian Wita, MD, PhD, Medical University of Silesia, Katowice, Poland, and colleagues.
The differences in duration and recanalization require further attention, they noted, and are related to a learning curve, more time dedicated to decision-making and, in some cases, needing a second opinion. Cardiologists performed 80 procedures compared with 116 for vascular surgeons and 52 for neuroradiologists, and treated twice as many patients with a previous stroke (13.9% vs. 6.5%).
Still, the interventional cardiologist- and noncardiologist-treated groups had similar functional independence at 3 months, defined by a modified Rankin Scale (mRS) score of 0 to 2 (44.4% vs. 54.8%; P = .275). Mortality was also similar at 3 months (31.3% vs. 28.0%; P = .595).
“This is the first analysis to prove the noninferiority of the cardiology services in the treatment of stroke with mechanical thrombectomy,” the authors reported in JACC: Cardiovascular Interventions.
But commenting for this news organization, J Mocco, MD, senior vice chair of neurosurgery and director of the Cerebrovascular Center at Mount Sinai Health System, New York, said this study isn’t designed as a noninferiority trial, is “grossly underpowered,” and the comparator cohort is not a gold standard comparator cohort.
“More importantly, they show that the cardiologists got significantly worse technical results and took longer, and we know that technical outcomes and the time to treatment are the two strongest predictors of outcome, which completely correlates with the fact that patients had 11% worse outcomes overall,” he said.
“It’s dumbfounding to me that this has been presented as evidence [that] an interventional cardiologist should be performing thrombectomy,” added Dr. Mocco, president-elect of the Society of NeuroInterventional Surgery.
Dr. Wita and coauthor Andrzej Kulach, MD, PhD, also with the Medical University of Silesia, told this news organization that timing is critical in mechanical thrombectomy (MT) and the sooner it’s performed, the better. But it cannot be performed by just any interventional cardiologist (IC).
“The IC must be trained in the procedure and cooperate with the neurologist to get good results,” they said. “We would like to stress that it is not a procedure for any cath lab and any cardiologist on duty. A network of cardiologists trained in MT must be organized and the stroke teams developed for the local unit to make the strategy reasonable and safe.”
The study was conducted from 2019 to 2020 and to participate, interventional cardiologists had to have performed a minimum of 700 angioplasties and 1,500 coronary angiographies and undergone complex training in thrombectomy, including 14-day training in a reference center and certified courses on a phantom and an animal model. They were also experienced in carotid angioplasty and participated as the second operators in neurointerventions.
“Considering the cardiologists are acting here in a multidisciplinary team led by neurologists, the findings are not surprising,” Dr. Wita and Dr. Kulach said. “What was surprising, is a certain level of skepticism among neurologists when cardiologists are to be involved in the procedure. We hope the quality of cardiology services will help to get over it.”
Major thrombectomy trials such as PRAGUE-16 have supported a role for interventional cardiologists to help meet demand for stroke thrombectomy. Dr. Wita and Dr. Kulach said there’s a lack of trained neuroradiologists and developed infrastructure for thrombectomy, whereas there’s a sufficient network of catheterization laboratories and trained cardiologists who could be involved.
The take-home message from the study, they said, is to “use the existing infrastructure to optimize the treatment of stroke. Building one from the very beginning is more time and resources-consuming.”
Dr. Mocco said a physician’s training is not a factor in the pathway to neurointerventional expertise, as long as they’re willing to put in the appropriate amount of specialization and training.
“There’s no way this represents a turf war or the neurology community somehow protecting its space, which is often used as a distraction, just like the idea that there’s not enough people,” he said. “It’s just not the case. Neurointervention is the most multispecialty space that I’m aware of.”
In the United States, at least, the problem isn’t a lack of resources or people to provide the service, but in getting patients to the correct hospitals, Dr. Mocco said. “We don’t have regionalized stroke care in the United States for the most part, so patients go to any hospital that says they provide stroke care rather than necessarily being triaged to capable centers that can provide the care.”
A 2021 Medicare analysis by Dr. Mocco and colleagues found that higher physician and hospital stroke thrombectomy volumes were associated with lower inpatient mortality and better outcomes.
Efforts are underway to regionalize care and delivery of patients in Los Angeles County and New York City, for example, where ambulances preferentially take patients with suspected large vessel occlusion to thrombectomy-capable stroke centers certified by independent organizations, Dr. Mocco said. In New York, “they’ve shown it has improved outcomes.”
Estêvão Carvalho de Campos Martins, MD, Hospital de Força Aérea do Galeão, Rio de Janeiro, and Fernando Luiz de Melo Bernardi, MD, Hospital Regional do Oeste, Chapecó, Brazil, noted in an accompanying editorial that the observational study is “hypothesis-generating only” and that the disconnect between technical and clinical outcomes is due to a type II error of low power.
They suggest that collaboration between specialties will be “essential for defining the optimal training program, so that ICs can reach solid procedural results.

Outcomes were mixed among ischemic stroke patients with large vessel occlusion who underwent thrombectomy by an interventional cardiologist as part of a multidisciplinary stroke team, in a single-center, prospective study from Poland.
Results from the 2-year experience show mechanical thrombectomy took longer when carried out by interventional cardiologists than by vascular surgeons and neuroradiologists (120 minutes vs. 105 minutes; P = .020).
The procedures were also less likely to achieve angiographic success, defined as a Thrombolysis in Cerebral Infarction (TICI) scale score of 2b or 3 (55.7% vs. 71.7%; P = .013), reported Krystian Wita, MD, PhD, Medical University of Silesia, Katowice, Poland, and colleagues.
The differences in duration and recanalization require further attention, they noted, and are related to a learning curve, more time dedicated to decision-making and, in some cases, needing a second opinion. Cardiologists performed 80 procedures compared with 116 for vascular surgeons and 52 for neuroradiologists, and treated twice as many patients with a previous stroke (13.9% vs. 6.5%).
Still, the interventional cardiologist- and noncardiologist-treated groups had similar functional independence at 3 months, defined by a modified Rankin Scale (mRS) score of 0 to 2 (44.4% vs. 54.8%; P = .275). Mortality was also similar at 3 months (31.3% vs. 28.0%; P = .595).
“This is the first analysis to prove the noninferiority of the cardiology services in the treatment of stroke with mechanical thrombectomy,” the authors reported in JACC: Cardiovascular Interventions.
But commenting for this news organization, J Mocco, MD, senior vice chair of neurosurgery and director of the Cerebrovascular Center at Mount Sinai Health System, New York, said this study isn’t designed as a noninferiority trial, is “grossly underpowered,” and the comparator cohort is not a gold standard comparator cohort.
“More importantly, they show that the cardiologists got significantly worse technical results and took longer, and we know that technical outcomes and the time to treatment are the two strongest predictors of outcome, which completely correlates with the fact that patients had 11% worse outcomes overall,” he said.
“It’s dumbfounding to me that this has been presented as evidence [that] an interventional cardiologist should be performing thrombectomy,” added Dr. Mocco, president-elect of the Society of NeuroInterventional Surgery.
Dr. Wita and coauthor Andrzej Kulach, MD, PhD, also with the Medical University of Silesia, told this news organization that timing is critical in mechanical thrombectomy (MT) and the sooner it’s performed, the better. But it cannot be performed by just any interventional cardiologist (IC).
“The IC must be trained in the procedure and cooperate with the neurologist to get good results,” they said. “We would like to stress that it is not a procedure for any cath lab and any cardiologist on duty. A network of cardiologists trained in MT must be organized and the stroke teams developed for the local unit to make the strategy reasonable and safe.”
The study was conducted from 2019 to 2020 and to participate, interventional cardiologists had to have performed a minimum of 700 angioplasties and 1,500 coronary angiographies and undergone complex training in thrombectomy, including 14-day training in a reference center and certified courses on a phantom and an animal model. They were also experienced in carotid angioplasty and participated as the second operators in neurointerventions.
“Considering the cardiologists are acting here in a multidisciplinary team led by neurologists, the findings are not surprising,” Dr. Wita and Dr. Kulach said. “What was surprising, is a certain level of skepticism among neurologists when cardiologists are to be involved in the procedure. We hope the quality of cardiology services will help to get over it.”
Major thrombectomy trials such as PRAGUE-16 have supported a role for interventional cardiologists to help meet demand for stroke thrombectomy. Dr. Wita and Dr. Kulach said there’s a lack of trained neuroradiologists and developed infrastructure for thrombectomy, whereas there’s a sufficient network of catheterization laboratories and trained cardiologists who could be involved.
The take-home message from the study, they said, is to “use the existing infrastructure to optimize the treatment of stroke. Building one from the very beginning is more time and resources-consuming.”
Dr. Mocco said a physician’s training is not a factor in the pathway to neurointerventional expertise, as long as they’re willing to put in the appropriate amount of specialization and training.
“There’s no way this represents a turf war or the neurology community somehow protecting its space, which is often used as a distraction, just like the idea that there’s not enough people,” he said. “It’s just not the case. Neurointervention is the most multispecialty space that I’m aware of.”
In the United States, at least, the problem isn’t a lack of resources or people to provide the service, but in getting patients to the correct hospitals, Dr. Mocco said. “We don’t have regionalized stroke care in the United States for the most part, so patients go to any hospital that says they provide stroke care rather than necessarily being triaged to capable centers that can provide the care.”
A 2021 Medicare analysis by Dr. Mocco and colleagues found that higher physician and hospital stroke thrombectomy volumes were associated with lower inpatient mortality and better outcomes.
Efforts are underway to regionalize care and delivery of patients in Los Angeles County and New York City, for example, where ambulances preferentially take patients with suspected large vessel occlusion to thrombectomy-capable stroke centers certified by independent organizations, Dr. Mocco said. In New York, “they’ve shown it has improved outcomes.”
Estêvão Carvalho de Campos Martins, MD, Hospital de Força Aérea do Galeão, Rio de Janeiro, and Fernando Luiz de Melo Bernardi, MD, Hospital Regional do Oeste, Chapecó, Brazil, noted in an accompanying editorial that the observational study is “hypothesis-generating only” and that the disconnect between technical and clinical outcomes is due to a type II error of low power.
They suggest that collaboration between specialties will be “essential for defining the optimal training program, so that ICs can reach solid procedural results.

Full results of anal cancer study point to barriers to care
Reports based on a press release in October 2021 suggested it, but now the full data tell the story:
“We now show, for the first time, that treatment of anal HSIL is effective in reducing the incidence of anal cancer,” said Joel Palefsky, MD, lead investigator of the Anal Cancer/HSIL Outcomes Research (ANCHOR) study and founder/director of the Anal Neoplasia Clinic at the University of California, San Francisco. “These data should be included in an overall assessment for inclusion of screening for and treating HSIL as standard of care in people living with HIV.”
Dr. Palefsky presented the full results in a special session at the Conference on Retroviruses and Opportunistic Infections, which drew excitement, gratitude, and relief from both researchers and clinicians, who flocked to the session.
But it’s not just people with HIV who will benefit from this research. Dr. Palefsky suggested that the findings should also be considered as guides for other people at high-risk for anal cancer, such as people who are immunocompromised for other reasons, including those with lupus, ulcerative colitis, Crohn’s disease, or cisgender women who have had vulvar or cervical cancer or precancer.
“If we can show efficacy in the most challenging group of all, which are people living with HIV, we think the results can be as good, if not even better, in the other groups at high risk of anal cancer,” Dr. Palefsky said.
But to serve anyone – whether living with HIV or not – infrastructure, algorithms, and workforce training are going be needed to meet the currently unserved people through use of high-resolution anoscopy (HRA) and other screening technology, he said.
Dr. Palefsy and colleagues screened 10,723 people living with HIV being served at 15 clinics nationwide. More than half, 52.2%, had anal HSIL – 53.3% of the cisgender men living with HIV in the trial, 45.8% of the cis women living with HIV, and a full 62.5% of transgender participants.
Those 4,446 participants were split evenly between the treatment arm and the control arm. Those in the treatment arm received treatment for HSIL on their first study visit via one of five options: hyfrecation, office-based electrocautery ablation, infrared coagulation, topical 5-fluorouracil cream, or topical imiquimod. Then, every 6 months after that, they came in for HRA, blood tests, anal Pap smears, and biopsies to check for any lingering or new HSIL. If clinicians found such cells, they received treatment again. If biopsies still showed HSIL and clinician and participant were worried about cancer, they could come in as frequently as every 3 months and receive treatment each time.
The active-monitoring control group still received an anal Pap smear, blood tests, biopsy, and HRA every 6 months – a level of care that is currently not mandated anywhere for people living with HIV, Dr. Palefsky said in an interview. They were also able to come in for more frequent monitoring (every 3 months) if clinicians were worried about cancer.
“Those in both arms would have been getting more attention than if they had not participated in the study,” he said.
In addition, during screening, researchers found that cancer was already present in 17 other people, who skipped the study to go right to treatment.
Participants reflected the demographics of the HIV epidemic in the United States. They were older (median age, 51 years), mostly gay (78%), and cisgender male (80%). Close to half, 42%, were Black, and 16% were Latinx. In addition, cisgender women made up 16% of the participants and transgender people, and nonbinary individuals accounted for more than 3% of the participants. In addition, one in three smoked.
The vast majority of participants had well-controlled HIV and healthy immune systems, though half in each arm had a history of AIDS, defined as lowest-ever CD4 immune cell counts below 200. Today, more than 80% of participants had undetectable viral loads, defined as a viral load less than 50 copies/mL, and another 7% had HIV viral loads below 200. In total, 9.3% in the treatment arm and 10.9% in the control arm had HIV viral loads higher than that. At time of enrollment, CD4 counts were above 600 in each group, indicating healthy immune systems.
Although all participants were there because they had anal HSIL, more than 1 in 10 – 13% – had abnormal cells so extensive that they covered more than half of the anal canal or the perianal region.
Once everyone was enrolled, researchers began monitoring and treatment, looking specifically for 31 cases of cancer – a number the team had determined that they’d need in order to draw any conclusions. Dr. Palefsky didn’t have to wait long. They were still trying to enroll the last 1,000 participants to have the power necessary to reach that number when the cancer diagnoses came in.
Dr. Palefsky told this news organization that the reason for that is unclear. It could be that some of those cases would have resolved on their own, and so the swiftness with which they reached the required number of cancer cases belies their seriousness. It could also be that the particular people who enrolled in this trial were engaging in behaviors that put them at even higher risk for anal cancer than the population of people living with HIV in the United States.
Or it could be that symptom-based screening is missing a lot of cancers that currently go untreated.
“So perhaps we will be seeing an increase in anal cancer reported in the future compared to the currently reported rates,” he said. “We don’t really know.”
Regardless of the reason for the speed to cases of cancer, the results were definitive: Nine participants were diagnosed with invasive anal cancer in the treatment arm, while 21 were diagnosed with invasive anal cancer in the control arm. That’s a 57% reduction in cancer occurrence between the arms. Or, to put it another way, the rate of anal cancer among people in the treatment arm was 173 per 100,000 people-years. In the active monitoring arm, it was 402 per 100,000 person-years. For context, the overall rate of anal cancer among people living with HIV is 50 per 100,000 person-years. The rate in the general U.S. population is 8 per 100,000 people-years.
The experimental treatment was such a definitive success that the investigators stopped the trial and shifted all participants in the control arm to treatment.
‘We have to build’
Before Dr. Palefsky was even done presenting the data, clinicians, people living with HIV, and experts at the session were already brainstorming as to how to get these results into practice.
“These data are what we have long needed to fuel some action on this important problem, including medical cost reimbursement through insurance and increasing the number of persons trained and capable in anal cancer screening,” John Brooks, MD, head of the epidemiology research team at the Centers for Disease Control and Prevention’s division of HIV/AIDS prevention, wrote in the virtual chat.
Jeff Taylor, a member of the ANCHOR advisory board and a person living with HIV who participated in one of the first azidothymidine trials in the late 1980s, responded quickly.
“What kind of advocacy from researchers, HIV clinicians and [people living with HIV] is needed to get this on treatment guidelines, HRA providers trained and certified, and payors to cover this so [people living with HIV] actually have access to lifesaving screening and [treatment]?” Mr. Taylor asked.
It’s a serious challenge. David Malebranche, MD, an Atlanta-based internal medicine physician who specializes in sexual health and HIV, commented in an interview. When he saw the initial press release last year on the ANCHOR findings, his first reaction was: “Thank god. We finally have some data to show what we’ve been trying to get people to do” all along.
But then he wondered, who is going to perform these tests? It’s a fair question. Currently, the wait for an HRA is 6-12 months in many parts of the country. And Dr. Malebranche can’t imagine this being added to his already full plate as a primary care provider.
“If you tell a primary care provider now that they have to do a rectal Pap smear, that’s going to be a problem while you’re also asking them to screen each patient for depression, anxiety, domestic abuse, intimate partner violence, all the healthcare maintenance and all the other screening tests – and then you deal with not only the urgent complaint but then all the complex medical issues on top of that – in a 15-minute or 10-minute visit,” he said.
Now that we have these data, he said, “we have to build.”
Dr. Palefsky agreed. Very few centers have enough people skilled at performing HRAs to meet the current demand, and it’s not realistic to expect clinicians to perform an HRA every 6 months like the study team did. There need to be algorithms put in place to help practitioners figure out who among their patients living with HIV could benefit from this increased screening, as well as biomarkers to identify HSIL progression and regression without the use of HRA, Dr. Palefsky told attendees. And more clinicians need to be recruited and trained to read HRAs, which can be difficult for the untrained eye to decipher.
Dr. Malebranche added another, more fundamental thing that needs to be built. Dr. Malebranche has worked in HIV clinics where the majority of his patients qualify for insurance under the Ryan White Program and get their medications through the AIDS Drug Assistance Program. While Ryan White programs can provide critical wraparound care, Dr. Malebranche has had to refer out for something like an HRA or cancer treatment. But the people who only access care through such programs may not have coverage with the clinics that perform HRA or that treat cancer. And that’s if they can even find someone to see them.
“If I live in a state like Georgia, which doesn’t have Medicaid expansion and we have people who are uninsured, where do you send them?” Dr. Malebranche asked. “This isn’t theoretical. I ran into this problem when I was working at the AIDS Healthcare Foundation last year. ... This is a call for infrastructure.”
The study was funded by the National Cancer Institute. Dr. Brooks reported no relevant financial relationships. Dr. Palefsky has received consultant fees from Merck, Vir Biotechnology, Virion Therapeutics, and Antiva Bioscience, as well as speaker fees from Merck. Dr. Malebranche has received consulting and advising fees from ViiV Healthcare.

There need to be algorithms put in place to help practitioners figure out who among their patients living with HIV could benefit from this increased screening, as well as biomarkers to identify HSIL progression and regression without the use of HRA, Dr. Palefsky told attendees. And more clinicians need to be recruited and trained to read HRAs, which can be difficult for the untrained eye to decipher.
Dr. Malebranche added another, more fundamental thing that needs to be built. Dr. Malebranche has worked in HIV clinics where the majority of his patients qualify for insurance under the Ryan White Program and get their medications through the AIDS Drug Assistance Program. While Ryan White programs can provide critical wraparound care, Dr. Malebranche has had to refer out for something like an HRA or cancer treatment. But the people who only access care through such programs may not have coverage with the clinics that perform HRA or that treat cancer. And that’s if they can even find someone to see them.
“If I live in a state like Georgia, which doesn’t have Medicaid expansion and we have people who are uninsured, where do you send them?” Dr. Malebranche asked. “This isn’t theoretical. I ran into this problem when I was working at the AIDS Healthcare Foundation last year. ... This is a call for infrastructure.”
The study was funded by the National Cancer Institute. Dr. Brooks reported no relevant financial relationships. Dr. Palefsky has received consultant fees from Merck, Vir Biotechnology, Virion Therapeutics, and Antiva Bioscience, as well as speaker fees from Merck. Dr. Malebranche has received consulting and advising fees from ViiV Healthcare.

Reports based on a press release in October 2021 suggested it, but now the full data tell the story:
“We now show, for the first time, that treatment of anal HSIL is effective in reducing the incidence of anal cancer,” said Joel Palefsky, MD, lead investigator of the Anal Cancer/HSIL Outcomes Research (ANCHOR) study and founder/director of the Anal Neoplasia Clinic at the University of California, San Francisco. “These data should be included in an overall assessment for inclusion of screening for and treating HSIL as standard of care in people living with HIV.”
Dr. Palefsky presented the full results in a special session at the Conference on Retroviruses and Opportunistic Infections, which drew excitement, gratitude, and relief from both researchers and clinicians, who flocked to the session.
But it’s not just people with HIV who will benefit from this research. Dr. Palefsky suggested that the findings should also be considered as guides for other people at high-risk for anal cancer, such as people who are immunocompromised for other reasons, including those with lupus, ulcerative colitis, Crohn’s disease, or cisgender women who have had vulvar or cervical cancer or precancer.
“If we can show efficacy in the most challenging group of all, which are people living with HIV, we think the results can be as good, if not even better, in the other groups at high risk of anal cancer,” Dr. Palefsky said.
But to serve anyone – whether living with HIV or not – infrastructure, algorithms, and workforce training are going be needed to meet the currently unserved people through use of high-resolution anoscopy (HRA) and other screening technology, he said.
Dr. Palefsy and colleagues screened 10,723 people living with HIV being served at 15 clinics nationwide. More than half, 52.2%, had anal HSIL – 53.3% of the cisgender men living with HIV in the trial, 45.8% of the cis women living with HIV, and a full 62.5% of transgender participants.
Those 4,446 participants were split evenly between the treatment arm and the control arm. Those in the treatment arm received treatment for HSIL on their first study visit via one of five options: hyfrecation, office-based electrocautery ablation, infrared coagulation, topical 5-fluorouracil cream, or topical imiquimod. Then, every 6 months after that, they came in for HRA, blood tests, anal Pap smears, and biopsies to check for any lingering or new HSIL. If clinicians found such cells, they received treatment again. If biopsies still showed HSIL and clinician and participant were worried about cancer, they could come in as frequently as every 3 months and receive treatment each time.
The active-monitoring control group still received an anal Pap smear, blood tests, biopsy, and HRA every 6 months – a level of care that is currently not mandated anywhere for people living with HIV, Dr. Palefsky said in an interview. They were also able to come in for more frequent monitoring (every 3 months) if clinicians were worried about cancer.
“Those in both arms would have been getting more attention than if they had not participated in the study,” he said.
In addition, during screening, researchers found that cancer was already present in 17 other people, who skipped the study to go right to treatment.
Participants reflected the demographics of the HIV epidemic in the United States. They were older (median age, 51 years), mostly gay (78%), and cisgender male (80%). Close to half, 42%, were Black, and 16% were Latinx. In addition, cisgender women made up 16% of the participants and transgender people, and nonbinary individuals accounted for more than 3% of the participants. In addition, one in three smoked.
The vast majority of participants had well-controlled HIV and healthy immune systems, though half in each arm had a history of AIDS, defined as lowest-ever CD4 immune cell counts below 200. Today, more than 80% of participants had undetectable viral loads, defined as a viral load less than 50 copies/mL, and another 7% had HIV viral loads below 200. In total, 9.3% in the treatment arm and 10.9% in the control arm had HIV viral loads higher than that. At time of enrollment, CD4 counts were above 600 in each group, indicating healthy immune systems.
Although all participants were there because they had anal HSIL, more than 1 in 10 – 13% – had abnormal cells so extensive that they covered more than half of the anal canal or the perianal region.
Once everyone was enrolled, researchers began monitoring and treatment, looking specifically for 31 cases of cancer – a number the team had determined that they’d need in order to draw any conclusions. Dr. Palefsky didn’t have to wait long. They were still trying to enroll the last 1,000 participants to have the power necessary to reach that number when the cancer diagnoses came in.
Dr. Palefsky told this news organization that the reason for that is unclear. It could be that some of those cases would have resolved on their own, and so the swiftness with which they reached the required number of cancer cases belies their seriousness. It could also be that the particular people who enrolled in this trial were engaging in behaviors that put them at even higher risk for anal cancer than the population of people living with HIV in the United States.
Or it could be that symptom-based screening is missing a lot of cancers that currently go untreated.
“So perhaps we will be seeing an increase in anal cancer reported in the future compared to the currently reported rates,” he said. “We don’t really know.”
Regardless of the reason for the speed to cases of cancer, the results were definitive: Nine participants were diagnosed with invasive anal cancer in the treatment arm, while 21 were diagnosed with invasive anal cancer in the control arm. That’s a 57% reduction in cancer occurrence between the arms. Or, to put it another way, the rate of anal cancer among people in the treatment arm was 173 per 100,000 people-years. In the active monitoring arm, it was 402 per 100,000 person-years. For context, the overall rate of anal cancer among people living with HIV is 50 per 100,000 person-years. The rate in the general U.S. population is 8 per 100,000 people-years.
The experimental treatment was such a definitive success that the investigators stopped the trial and shifted all participants in the control arm to treatment.
‘We have to build’
Before Dr. Palefsky was even done presenting the data, clinicians, people living with HIV, and experts at the session were already brainstorming as to how to get these results into practice.
“These data are what we have long needed to fuel some action on this important problem, including medical cost reimbursement through insurance and increasing the number of persons trained and capable in anal cancer screening,” John Brooks, MD, head of the epidemiology research team at the Centers for Disease Control and Prevention’s division of HIV/AIDS prevention, wrote in the virtual chat.
Jeff Taylor, a member of the ANCHOR advisory board and a person living with HIV who participated in one of the first azidothymidine trials in the late 1980s, responded quickly.
“What kind of advocacy from researchers, HIV clinicians and [people living with HIV] is needed to get this on treatment guidelines, HRA providers trained and certified, and payors to cover this so [people living with HIV] actually have access to lifesaving screening and [treatment]?” Mr. Taylor asked.
It’s a serious challenge. David Malebranche, MD, an Atlanta-based internal medicine physician who specializes in sexual health and HIV, commented in an interview. When he saw the initial press release last year on the ANCHOR findings, his first reaction was: “Thank god. We finally have some data to show what we’ve been trying to get people to do” all along.
But then he wondered, who is going to perform these tests? It’s a fair question. Currently, the wait for an HRA is 6-12 months in many parts of the country. And Dr. Malebranche can’t imagine this being added to his already full plate as a primary care provider.
“If you tell a primary care provider now that they have to do a rectal Pap smear, that’s going to be a problem while you’re also asking them to screen each patient for depression, anxiety, domestic abuse, intimate partner violence, all the healthcare maintenance and all the other screening tests – and then you deal with not only the urgent complaint but then all the complex medical issues on top of that – in a 15-minute or 10-minute visit,” he said.
Now that we have these data, he said, “we have to build.”
Dr. Palefsky agreed. Very few centers have enough people skilled at performing HRAs to meet the current demand, and it’s not realistic to expect clinicians to perform an HRA every 6 months like the study team did. There need to be algorithms put in place to help practitioners figure out who among their patients living with HIV could benefit from this increased screening, as well as biomarkers to identify HSIL progression and regression without the use of HRA, Dr. Palefsky told attendees.

FROM CROI 2022
FDA approves first drug for rare inherited anemia
The new drug, mitapivat (Pyrukynd, Agios), was approved on the basis of clinical trials that showed that it significantly improved hemolysis and anemia in patients with PK deficiency.
PK deficiency is rare. In clinical practice, its frequency is approximately 3-9 cases per 1 million people, the FDA noted. However, PK deficiency likely is misdiagnosed or undiagnosed, making it difficult to determine its frequency in the general population
PK deficiency is an inherited disorder that causes premature red blood cell destruction, leading to anemia, the agency explained in its announcement. Symptoms of PK deficiency range in severity and include fatigue, unusually pale skin, jaundice, shortness of breath, and a fast heart rate. Patients can also develop an enlarged spleen, can have too much iron in their blood from repeated blood transfusions, and can develop gallstones.
“Pyrukynd is the first approved therapy for PK deficiency and marks an important milestone for these patients, who may face tremendous challenges and debilitating symptoms throughout the course of this lifelong disease,” said Rachael Grace, MD, pediatric hematologist and director of hematology clinical research at Boston Children’s Hospital.
She was an investigator in the clinical trials that led to the approval. In a statement from the manufacturer, she added that “partnering with Agios and the PK deficiency community to improve understanding of the natural history of this rare disease and bring a new medicine to patients has been an honor, and I look forward to additional collaboration in the future.”
Clinical data
Clinical data that formed the basis of the approval came from two trials, one of which was a randomized, placebo-controlled trial, and the other a single-arm study, the FDA noted. In these studies, patients received up to 50 mg of mitapivat orally twice daily after an initial dose titration period
The randomized trial involved 80 adults with PK deficiency who were not having regular blood transfusions. They were allocated to receive either mitapivat or placebo and were followed for an average of 24 weeks. The primary endpoint was the number of patients who achieved a hemoglobin response (defined as a 1.5 g/dL or greater increase in hemoglobin concentration that was sustained at two or more scheduled assessments). At the end of the study, 40% of participants who received mitapivat had a hemoglobin response, compared with no participants who received placebo.
The single-arm study involved 27 adults with PK deficiency who were receiving regular blood transfusions. They took mitapivat for an average of 40 weeks. In this study, the primary endpoint was the reduction in transfusion burden, defined as at least a 33% reduction in the number of red blood cell units transfused during the last 24 weeks of treatment, compared with the historical transfusion burden on the individual participant (standardized to 24 weeks). The results show that 33% of participants who received mitapivat met this reduction in transfusion burden; 22% of participants did not require any transfusions over the last 24 weeks of treatment.
The most common side effects reported were decreases in estrone and estradiol in men, increased urate level, back pain, and joint stiffness. The effects of estrone and estradiol could not be reliably assessed in women because of normal changes in these hormone levels during the menstrual cycle and use of hormonal contraception.
The FDA warns of drug interactions that could necessitate dose adjustments, and also that abruptly stopping mitapivat could worsen premature red blood cell destruction.
The agency noted that this application received orphan drug designation, fast track designation, and priority review.
Agios is offering access programs aimed at reducing or eliminating patient out-of-pocket costs. Further details are on the myAgios patient support services program.
The company also noted that mitapivat is awaiting approval in the European Union. A decision is expected before the end of 2022.

Third transplant patient cured of HIV marks important firsts
that has plagued the world for decades.
But while this case is certainly cause for celebration, experts involved in the effort say we are still a long way from a universal cure.
Researcher Yvonne Bryson, MD, chief of pediatric infectious diseases at the University of California, Los Angeles, told those attending the Conference on Retroviruses and Opportunistic Infections that this case is special. The patient was a woman living with HIV who is multiracial. The previous two patients were men: one white, one Latinx.
The woman in this case was given transplants of stem cells and umbilical cord blood to treat leukemia. The treatment not only sent her cancer into remission, but her HIV as well.
The success of this case suggests that cord stem cell transplants should be considered to produce remission and cure for those with HIV who also have cancers and other diseases, the researchers said.
While the news was met with excitement in the scientific community, the approach will not be available universally, since the transplants were all done to treat cancers in the three HIV-infected patients. Overall, Dr. Bryson estimates that about 50 people per year may benefit from this procedure.
Even so, other experts say the approach could provide insight into other ways to find cures. And Dr. Bryson says it opens up options for more diverse populations.
“A bone marrow transplant is not a viable large-scale strategy for curing HIV, but it does present a proof of concept that HIV can be cured,” said Sharon Lewin, MD, president-elect of the International AIDS Society. “It also further strengthens using gene therapy as a viable strategy for an HIV cure.”
The woman needed a stem cell transplant after being diagnosed with leukemia. The stem cell transplant technique used was also novel, Dr. Bryson said. The medical team used a combination of adult stem cells from a relative’s blood and umbilical cord blood from a cord-blood bank that had a rare mutation that makes the immune system resistant to HIV.
In the previous two cases of HIV cures after transplants, both patients were treated with stem cell transplants, with the same mutation, but from bone marrow transplants, a more difficult procedure. And no cord blood was used for those.
The combination of adult cells and cord-blood cells proved to be the ticket to success. Using the adult cells provides a kind of bridge that helps until the cord blood takes over, the researchers said. By day 100 after the transplant, Dr. Bryson said, the woman basically had a new immune system.
HIV remained undetectable in T cells and in bone marrow. And 37 months after the transplant, the woman stopped taking the antiretroviral treatment commonly given to treat HIV infection.
‘’She is currently clinically well,” Dr. Bryson said. Her cancer is in remission.
Case histories: Three patients
The woman, who is middle-aged, has requested privacy, asking that neither her age nor other details be released. But the researchers did provide some background on her medical history and her route back to health. She was diagnosed with HIV in 2013 and began treatment with antiretroviral therapy (ART). Four years after her HIV diagnosis, she developed high-risk acute myelogenous leukemia. The transplant was done to treat that.
Her recovery was much less bumpy than that of the previous two patients, the researchers said. She left the hospital 17 days after the transplant. She didn’t have serious complications like the first two, who developed a condition that occurs when donor bone marrow or stem cells attack the recipient.
“This case also suggests that it’s the transplant of HIV-resistant cells that was key to achieving a cure here,” said Dr. Lewin. The first patient who had HIV remission after a stem cell transplant, a White man, stayed in remission for 12 years and was termed cured. But he died of leukemia in September 2020. The other, a Latinx man, has been in remission for more than 30 months.
HIV statistics, ethnic/racial burdens
In the United States, about 1.2 million people have HIV, according to HIV.gov. Thirteen percent of those who have it do not know they have it. In 2019, 34,800 new infections were diagnosed.
Certain ethnic and racial groups are more affected by HIV than others, given their proportions in the U.S. population, federal statistics suggest. In 2019, for instance, African Americans were 13% of the U.S. population but 40% of those with HIV. Hispanics/Latinx represented 18.5% of the total population but 25% of those diagnosed with HIV.
Disparities also affect women unequally, with Black women disproportionately affected, compared to women of other ethnic and racial groups. Annual HIV infections remained stable overall among Black women from 2015 to 2019, but the rate of new HIV infections among Black women is 11 times that of White women and 4 times that of Latinx, according to federal statistics.
Expert perspective, reactions
Vincent Marconi, MD, professor of infectious diseases at Emory University, Atlanta, whose research focuses on disparities in HIV treatment responses, called the news “an exciting development for the cure agenda. This is the first woman to have been cured for at least 14 months, and they used cord blood, which could allow for potentially less toxic regimens and fewer adverse effects.”
Although the approach, meant to be used to treat the cancers, will not be widely available, he said that ‘’it does provide insight into somewhat related alternative models of cure involving gene therapy.”
Meanwhile, Dr. Marconi and other researchers are focusing on the concept of long-term HIV remission if a cure is not possible. Among the strategies under study are gene editing and immune-based treatments. HIV remission is generally defined as having an HIV viral load that is not detectable after stopping treatment.

The woman in this case was given transplants of stem cells and umbilical cord blood to treat leukemia. The treatment not only sent her cancer into remission, but her HIV as well.
The success of this case suggests that cord stem cell transplants should be considered to produce remission and cure for those with HIV who also have cancers and other diseases, the researchers said.
While the news was met with excitement in the scientific community, the approach will not be available universally, since the transplants were all done to treat cancers in the three HIV-infected patients. Overall, Dr. Bryson estimates that about 50 people per year may benefit from this procedure.
Even so, other experts say the approach could provide insight into other ways to find cures. And Dr. Bryson says it opens up options for more diverse populations.
“A bone marrow transplant is not a viable large-scale strategy for curing HIV, but it does present a proof of concept that HIV can be cured,” said Sharon Lewin, MD, president-elect of the International AIDS Society. “It also further strengthens using gene therapy as a viable strategy for an HIV cure.”
The woman needed a stem cell transplant after being diagnosed with leukemia. The stem cell transplant technique used was also novel, Dr. Bryson said. The medical team used a combination of adult stem cells from a relative’s blood and umbilical cord blood from a cord-blood bank that had a rare mutation that makes the immune system resistant to HIV.
In the previous two cases of HIV cures after transplants, both patients were treated with stem cell transplants, with the same mutation, but from bone marrow transplants, a more difficult procedure. And no cord blood was used for those.
The combination of adult cells and cord-blood cells proved to be the ticket to success. Using the adult cells provides a kind of bridge that helps until the cord blood takes over, the researchers said. By day 100 after the transplant, Dr. Bryson said, the woman basically had a new immune system.
HIV remained undetectable in T cells and in bone marrow. And 37 months after the transplant, the woman stopped taking the antiretroviral treatment commonly given to treat HIV infection.
‘’She is currently clinically well,” Dr. Bryson said. Her cancer is in remission.
Case histories: Three patients
The woman, who is middle-aged, has requested privacy, asking that neither her age nor other details be released. But the researchers did provide some background on her medical history and her route back to health. She was diagnosed with HIV in 2013 and began treatment with antiretroviral therapy (ART). Four years after her HIV diagnosis, she developed high-risk acute myelogenous leukemia. The transplant was done to treat that.
Her recovery was much less bumpy than that of the previous two patients, the researchers said. She left the hospital 17 days after the transplant. She didn’t have serious complications like the first two, who developed a condition that occurs when donor bone marrow or stem cells attack the recipient.
“This case also suggests that it’s the transplant of HIV-resistant cells that was key to achieving a cure here,” said Dr. Lewin. The first patient who had HIV remission after a stem cell transplant, a White man, stayed in remission for 12 years and was termed cured. But he died of leukemia in September 2020. The other, a Latinx man, has been in remission for more than 30 months.
HIV statistics, ethnic/racial burdens
In the United States, about 1.2 million people have HIV, according to HIV.gov. Thirteen percent of those who have it do not know they have it. In 2019, 34,800 new infections were diagnosed.
Certain ethnic and racial groups are more affected by HIV than others, given their proportions in the U.S. population, federal statistics suggest. In 2019, for instance, African Americans were 13% of the U.S. population but 40% of those with HIV. Hispanics/Latinx represented 18.5% of the total population but 25% of those diagnosed with HIV.
Disparities also affect women unequally, with Black women disproportionately affected, compared to women of other ethnic and racial groups. Annual HIV infections remained stable overall among Black women from 2015 to 2019, but the rate of new HIV infections among Black women is 11 times that of White women and 4 times that of Latinx, according to federal statistics.
Expert perspective, reactions
Vincent Marconi, MD, professor of infectious diseases at Emory University, Atlanta, whose research focuses on disparities in HIV treatment responses, called the news “an exciting development for the cure agenda. This is the first woman to have been cured for at least 14 months, and they used cord blood, which could allow for potentially less toxic regimens and fewer adverse effects.”
Although the approach, meant to be used to treat the cancers, will not be widely available, he said that ‘’it does provide insight into somewhat related alternative models of cure involving gene therapy.”
Meanwhile, Dr. Marconi and other researchers are focusing on the concept of long-term HIV remission if a cure is not possible. Among the strategies under study are gene editing and immune-based treatments. HIV remission is generally defined as having an HIV viral load that is not detectable after stopping treatment.
