Monitoring limited in stage 3 chronic kidney disease
SAN DIEGO – Fewer than a quarter of patients with signs of stage 3 chronic kidney disease (CKD) underwent follow-up testing within 1 year, even though most of these patients underwent repeat cholesterol screening during the same time.
Considering that CKD can be asymptomatic until the late stages, “this is a lost opportunity to get a proper evaluation by a nephrologist,” study coauthor and nephrologist Barbara S. Gillespie, MD, MMS, of Covance, the drug development business of LabCorp, said in an interview. Dr. Gillespie and her colleagues presented their findings at Kidney Week 2018, sponsored by the American Society of Nephrology.
More than 90% of patients with stages 1-3 CKD didn’t know they had the condition, based on 2013-2016 data gathered by the United States Renal Data System . Just 57% of those with stage 4 CKD were aware of their disease.
For the retrospective study, the researchers identified 4.9 million patients (58% were women; mean age was 71) who had estimated glomerular filtration rate (eGFR) results below 60 mL/min per 1.73 m2 from 2011 to 2018, based on serum creatinine tests performed at least twice and at least 3 months apart by LabCorp. The researchers tracked the patients for a median 26 months.
Based on the initial results, 92% of the patients had stage 3 CKD, 6% had stage 4, and 2% had stage 5. However, at 1 year, the percentages of overall patients who underwent urine albumin/creatinine ratio, serum phosphorus, and plasma parathyroid hormone were 24%, 12%, and 17%, respectively, lead author Jennifer Ennis, MD, of LabCorp, said in an interview.
Kidney Disease Improving Global Outcomes guidelines from 2012 recommend “assessments of GFR and albuminuria at least annually ... and more often for individuals at higher risk of progression, and/or where measurement will impact therapeutic decisions” (Ann Intern Med. 2013 Jun 4;158[11]:825-30).
Yet 76% of these patients also underwent annual LDL cholesterol screening. “This suggests that the patients were receiving evaluation and treatment for other common conditions, but that CKD may not have been specifically addressed,” Dr. Ennis said.
“These results suggest that guideline recommendations for monitoring of CKD are not well implemented in the primary care setting, which is where the majority of this testing took place,” she added. “There are possibly many reasons for this, including lack of guideline awareness, familiarity, or agreement; inertia; or other external barriers such as time constraints and the burden of having to remember numerous guidelines for a single patient with multiple conditions.”
Dr. Gillespie said the findings may help to explain why so many patients with CKD are unaware of their condition and “crash into dialysis” within 24 hours of winding up in the emergency department with kidney failure. “Often they note they did not know they had kidney disease,” she said, “or did not know how bad it was.”

Dialysis decision in elderly needs to factor in comorbidities
SAN DIEGO – The wider picture of the patient’s health and prognosis, not just chronologic age, should enter into the clinical decision to initiate dialysis, according to Bjorg Thorsteinsdottir, MD, a palliative care physician at the Mayo Clinic in Rochester, Minn.
“People perceive they have no choice [but treatment], and we perceive we have to do things to them until everything is lost, then we expect them to do a 180 [degree turn],” she said in a presentation at the meeting sponsored by the American Society of Nephrology.
“A 90-year-old fit individual, with minimal comorbidity living independently, would absolutely be a good candidate for dialysis, while a 75-year-old patient with bad peripheral vascular disease and dementia, living in a nursing home, would be unlikely to live longer on dialysis than off dialysis,” she said. “We need to weigh the risks and benefits for each individual patient against their goals and values. We need to be honest about the lack of benefit for certain subgroups of patients and the heavy treatment burdens of dialysis. Age, comorbidity, and frailty all factor into these deliberations and prognosis.”
More than 107,000 people over age 75 in the United States received dialysis in 2015, according to statistics gathered by the National Kidney Foundation. Yet the survival advantage of dialysis is more limited in elderly patients with multiple comorbidities, Dr. Thorsteinsdottir said. “It becomes important to think about the harms of treatment.”
A 2016 study from the Netherlands found no survival advantage to dialysis, compared with conservative management among kidney failure patients aged 80 and older. The survival advantage was limited with dialysis in patients aged 70 and older who also had multiple comorbidities. (Clin J Am Soc Nephrol. 2016 Apr;11(4):633-40)
In an interview, Dr. Thorsteinsdottir acknowledged that “determining who is unlikely to benefit from dialysis is complicated.” However, she said, “we know that the following comorbidities are the worst: dementia and peripheral vascular disease.”
“No one that I know of currently has an age cutoff for dialysis,” Dr. Thorsteinsdottir said in the interview, “and I do not believe the U.S. is ready for any kind of explicit limit setting by the government on dialysis treatment.”
“We must respond to legitimate concerns raised by recent studies that suggest that strong moral imperatives – to treat anyone we can treat – have created a situation where we are not pausing and asking hard questions about whether the patient in front of us is likely to benefit from dialysis,” she said in the interview. “Patients sense this and do not feel that they are given any alternatives to dialysis treatment. This needs to change.”
Dr. Thorsteinsdottir reported no relevant financial disclosures.

Good news, bad news about HCV in kidney disease
SAN DIEGO – There’s good news and bad news about hepatitis C virus (HCV) in patients with chronic kidney disease (CKD): The new generation of drugs that cures HCV is effective in this population, but outbreaks of infection are still plaguing the nation’s dialysis clinics.
These perspectives came in a presentation about infections in CKD at Kidney Week 2018, sponsored by the American Society of Nephrology.
First, the good news about HCV. “Treatment is now feasible for all stages of chronic kidney disease,” said gastroenterologist Paul Martin, MD, of the University of Miami. “It was possible to achieve biological cure in 99% of patients, which is truly remarkable considering what a problem kidney patients were for hepatitis C until very recently.”
The key is to treat HCV with drug combinations that lower the risk of viral resistance. “These drugs are extremely well tolerated. They’re not like interferon or ribavirin,” he said, referring to a drug combo that was formerly used to treat HCV. “We can anticipate curing hepatitis C with a finite amount of therapy in virtually every patient we see, including those with kidney disease.”
In patients with CKD, all the new drugs are approved for glomerular filtration rates greater than 30 mL/min. Sofosbuvir (Sovaldi) is not approved for patients with a filtration rate under 30 mL/min, he said, but other options are available.
Ribavirin, he added, is no longer needed with current regimens.
Dr. Martin pointed to two studies that reveal the power of the new regimens against HCV in patients with CKD. One of the studies, a 2015 industry-funded report in the Lancet, found that “once-daily grazoprevir and elbasvir for 12 weeks had a low rate of adverse events and was effective in patients infected with HCV genotype 1 and stage 4-5 chronic kidney disease.” The other study, also funded by industry and published in 2017 in the New England Journal of Medicine, found that “treatment with glecaprevir and pibrentasvir for 12 weeks resulted in a high rate of sustained virologic response in patients with stage 4 or 5 chronic kidney disease and HCV infection.”
Meanwhile, there are signs that HCV treatment may boost survival in CKD patients on dialysis, Dr. Martin said.
In terms of bad news, Priti R. Patel, MD, MPH, a medical officer with the Centers for Disease Control and Prevention, warned that dialysis clinics are still seeing HCV outbreaks. “It’s a continuing problem,” she said. “What we hear about at the CDC is the tip of the iceberg.”
The CDC says it received word of 21 HCV outbreaks of two or more cases in dialysis clinics during 2008-2017. These affected 102 patients, and more than 3,000 patients were notified that they were at risk and should be screened.
One dialysis clinic in Philadelphia had 18 cases of HCV during 2008-2013; they were blamed on “multiple lapses in infection control ... including hand hygiene and glove use, vascular access care, medication preparation, cleaning, and disinfection.”
“There should be no more than one case that has to happen for a facility to detect that it has a problem and identify a solution,” Dr. Patel said.
Since acute HCV can appear without symptoms, every dialysis patients should be tested for HCV antibodies, she added. “If it’s positive, confirm it. If confirmed, they should be informed of their infection status and have an evaluation for treatment.”
Dr. Martin reported consulting for Bristol-Myers Squibb and AbbVie and receiving research funding from Gilead, Bristol-Myers Squibb, AbbVie, and Merck. Dr. Patel reported no disclosures.

EXPERT ANALYSIS FROM KIDNEY WEEK 2018
DPP-4 drugs for diabetes may protect kidneys too
SAN DIEGO – Dipeptidyl peptidase–4 (DPP-4) inhibitors appear to delay the progression of chronic kidney disease (CKD) in patients with type 2 diabetes mellitus (T2DM), a new study has found. Researchers also found that all-cause long-term mortality dropped by an astonishing 78% in patients who took the drugs for an average of more than 3 years.
While the reasons for the impressive mortality results are a mystery, “these medications could have a beneficial effect on the kidneys, and it begins to show after 3 years,” said lead author Mariana Garcia-Touza, MD, of the Kansas City (Missouri) Department of Veterans Affairs Medical Center, in an interview. She presented the results at the meeting, sponsored by the American Society of Nephrology.
DPP-4 inhibitor drugs have been available for more than a decade in the United States. The medications, which include sitagliptin (Januvia) and linagliptin (Tradjenta), are used to treat patients with T2DM who are inadequately controlled by first-line treatments.
The drugs have critics. As UpToDate notes, they’re expensive and their effect on glucose levels is “modest.” In addition, UpToDate says, “some of the DPP-4 inhibitors have been associated with an increased risk of heart failure resulting in hospitalization.”
The authors of the new study sought to understand whether the drugs affect kidney function. As Dr. Garcia-Touza noted, metformin, which is processed in part by the kidneys, is considered harmful to certain patients with kidney disease. However, DPP-4 inhibitors are cleared through the liver. In fact, research has suggested the drugs may actually benefit the liver (Med Sci Monit. 2014 Sep 17;20:1662-7).
For the new study, researchers retrospectively analyzed 20,424 patients with T2DM in the VA system who took DPP-4 inhibitors (average age, 68 years) and compared them with a matched group of 52,118 patients with T2DM who didn’t take the drugs, tracking all patients for a mean of over 3 years.
T2DM control improved slightly in the DPP-4 group but remained worse than the non–DPP-4 group. However, “a significant reduction in progression of CKD was seen” in the DPP-4 group, she said.
The number of patients with creatinine levels above 1.5 mg/dL, 3 mg/dL, and 6 mg/dL was reduced by 7%, 41%, and 47%, respectively, in the DPP-4 group, compared with the other group (P less than .01). And the time to end-stage renal disease (creatinine above 6 mg/dL) was delayed by 144 days in the DPP-4 group (P less than .01).
All-cause mortality also fell by 78% in the DPP-4 group (P less than .0001). “Despite having worse glucose control [than the non–DPP-4 group], these patients have better overall mortality,” Dr. Garcia-Touza said.
The drugs may reduce the burden on the kidneys by decreasing inflammation, she said.
Could DPP-4 drugs be beneficial to patients with CKD even if they don’t have T2DM? Dr. Garcia-Touza wasn’t sure. However, she had a theory about why these kidney benefits didn’t show up in previous research. “My impression is that they didn’t go far enough [in time]. That was the main difference.”
Going forward, Dr. Garcia-Touza said her team plans to study the effects of the drugs on retinopathy and diabetic neuropathy.
The study was funded by the Midwest Biomedical Research Foundation and the VA. The study authors reported no relevant disclosures.

The number of patients with creatinine levels above 1.5 mg/dL, 3 mg/dL, and 6 mg/dL was reduced by 7%, 41%, and 47%, respectively, in the DPP-4 group, compared with the other group (P less than .01). And the time to end-stage renal disease (creatinine above 6 mg/dL) was delayed by 144 days in the DPP-4 group (P less than .01).
All-cause mortality also fell by 78% in the DPP-4 group (P less than .0001). “Despite having worse glucose control [than the non–DPP-4 group], these patients have better overall mortality,” Dr. Garcia-Touza said.
The drugs may reduce the burden on the kidneys by decreasing inflammation, she said.
Could DPP-4 drugs be beneficial to patients with CKD even if they don’t have T2DM? Dr. Garcia-Touza wasn’t sure. However, she had a theory about why these kidney benefits didn’t show up in previous research. “My impression is that they didn’t go far enough [in time]. That was the main difference.”
Going forward, Dr. Garcia-Touza said her team plans to study the effects of the drugs on retinopathy and diabetic neuropathy.
The study was funded by the Midwest Biomedical Research Foundation and the VA. The study authors reported no relevant disclosures.

SAN DIEGO – Dipeptidyl peptidase–4 (DPP-4) inhibitors appear to delay the progression of chronic kidney disease (CKD) in patients with type 2 diabetes mellitus (T2DM), a new study has found. Researchers also found that all-cause long-term mortality dropped by an astonishing 78% in patients who took the drugs for an average of more than 3 years.
While the reasons for the impressive mortality results are a mystery, “these medications could have a beneficial effect on the kidneys, and it begins to show after 3 years,” said lead author Mariana Garcia-Touza, MD, of the Kansas City (Missouri) Department of Veterans Affairs Medical Center, in an interview. She presented the results at the meeting, sponsored by the American Society of Nephrology.
DPP-4 inhibitor drugs have been available for more than a decade in the United States. The medications, which include sitagliptin (Januvia) and linagliptin (Tradjenta), are used to treat patients with T2DM who are inadequately controlled by first-line treatments.
The drugs have critics. As UpToDate notes, they’re expensive and their effect on glucose levels is “modest.” In addition, UpToDate says, “some of the DPP-4 inhibitors have been associated with an increased risk of heart failure resulting in hospitalization.”
The authors of the new study sought to understand whether the drugs affect kidney function. As Dr. Garcia-Touza noted, metformin, which is processed in part by the kidneys, is considered harmful to certain patients with kidney disease. However, DPP-4 inhibitors are cleared through the liver. In fact, research has suggested the drugs may actually benefit the liver (Med Sci Monit. 2014 Sep 17;20:1662-7).
For the new study, researchers retrospectively analyzed 20,424 patients with T2DM in the VA system who took DPP-4 inhibitors (average age, 68 years) and compared them with a matched group of 52,118 patients with T2DM who didn’t take the drugs, tracking all patients for a mean of over 3 years.

REPORTING FROM KIDNEY WEEK 2018
Key clinical point: Dipeptidyl peptidase–4 (DPP-4) inhibitors may delay progression of chronic kidney disease in patients with type 2 diabetes mellitus (T2DM) and may dramatically reduce all-cause mortality.
Major finding: Compared with those who didn’t take the drugs, patients with T2DM who took DPP-4 inhibitors were much less likely to progress to creatinine levels above 1.5 mg/dL, 3 mg/dL, and 6 mg/dL (reduction of 7%, 41%, and 47%, respectively; P less than .01). All-cause mortality in the DPP-4 group fell by 78% (P less than .0001).
Study details: A retrospective study of 20,424 patients with T2DM in the Department of Veterans Affairs system who took DPP-4 inhibitors for mean of more than 3 years and a matched group of 52,118 patients with T2DM who didn’t take the drugs.
Disclosures: The study was funded by the Midwest Biomedical Research Foundation and the VA. The study authors reported no relevant disclosures.

Dark-roast dementia, cocktail dermatitis, and violent good guys
Dark roast has the most
The most … best chance … dark-roast coffee may protect your brain against Parkinson’s disease, okay? Rhyming can be hard. A Canadian study recently found that the compounds in brewed coffee, called phenylindanes, may have neuroprotective effects by inhibiting amyloid-beta, tau, or alpha-synuclein. Researchers examined light roast, dark roast, and decaf dark roast and concluded that the dark roast contains stronger inhibitors. We always figured those ridiculous light-roast coffees were for the weak, but now we have proof.
Researchers also looked at the effect of caffeine. Sweet, sweet caffeine. While a potent psychoactive component, pure caffeine appeared to have no effect on amyloid-beta, tau, or alpha-synuclein aggregation. Does this mean coffee is the cure for Parkinson’s disease? Not quite yet, but keep on chuggin’. And while you’re at it, have some pomegranate, too.
Cocktail dermatitis
Dermatologist Vincent DeLeo, MD, isn’t a psychic or a seer. But he plays one in the examination room. Every now and then, a patient walks in with noninflammatory blisters or hyperpigmentation, often on their hands. Dr. DeLeo takes a look and asks if the patient was enjoying some gin and tonics the previous weekend. “They think you’re God because of course they were,” he told an audience at the recent Coastal Dermatology Symposium.
The culprit? An allergy to the dark green skin of limes, a.k.a. “margarita photodermatitis.” Dr. DeLeo says it may take a few days for the blisters to appear. And he advised colleagues to not photo test the patient because it could make things worse. As for treatment, steroids can help. So can switching to Scotch and soda.
The animals are getting high
Australian animals are getting a contact high, according to a research team that studied stream invertebrates around Melbourne. When we consume pharmaceuticals, our bodies do not totally absorb them. Now, evidence shows that the residual drugs that leave our system are ending up in waterways. What does that mean? It means animals are getting free drugs, and that’s just not fair.
The water-dwelling invertebrates are also passing on these residual compounds to other animals, like spiders who eat invertebrate larvae. Researchers also predicted that platypuses in particular might soon be exposed to high levels of antidepressants. At least the platypuses will be happy.
Health care goes to the movies
Science, as many of those involved in the time-honored but often misunderstood pursuit of truthiness would agree, is a strange, wonderful, yet fickle mistress. One day, she’ll have you comparing the quantity and quality of infant stools or shoving whooping cough bacteria up people’s noses. And the next day, she’ll invite you to join her at the local mega-movie multiplex for the latest Hollywood blockbuster.
Just ask Robert Olympia, MD, of Penn State University, Hershey, and his associates, who watched 10 superhero-based films from 2015 and 2016 and counted the violent acts committed by “good guys” and “bad guys.” Their analysis, presented at the annual meeting of the American Academy of Pediatrics in Orlando, shows that good guys committed 23 violent acts per hour, compared with 18 per hour for the bad guys. Young people who watch these movies “may be influenced by their portrayal of risk-taking behaviors and acts of violence. … Pediatric health care providers should educate families about the violence depicted in this genre of film and the potential dangers that may occur when children attempt to emulate these perceived heroes,” said Dr. Olympia.
Of course, his own superhero-ready name suggests that he may be battling – in a nonviolent way, we’re sure – Bleeding Ulcer, The Bowel Movement, Anal Fissure, Migraineur, and/or The Endoscopist in the next Avengers movie.

Experience – not evidence – is best guide in keloid treatment
LAS VEGAS – The first written mention of keloids in history came about 4,500 years ago. But there is still so much more to be learned about keloids, according to dermatologist Hilary E. Baldwin, MD.
Yes, there is more information about who gets keloids and where they appear on the body. “What we do not know is everything else,” Dr. Baldwin said at Skin Disease Education Foundation’s annual Las Vegas Dermatology Seminar. “We don’t even know which treatments work. Not a single treatment has any evidence basis behind it. It’s all fly-by-night, seat-of-your-pants, based on your knowledge and that of those who treat keloids frequently.”
. Cases show an unknown factor serves as a contributing factor, she said.
There’s no gender disparity in keloids, she said, and they’re more likely to occur after puberty than before. Family history isn’t helpful.
Also, while darker skin produces keloids more easily and consistently than other skin types, these keloids aren’t the hardest to treat, said Dr. Baldwin, medical director of the Acne Treatment and Research Center in Morristown, N.J. “From my personal experience – but not from data or papers – keloids are the most difficult to treat and recur the most when you see them in a Caucasian patient.”
Patients want the keloids to disappear forever along with any evidence that they ever existed. “Virtually every patient says ‘I want this cut off, I want it gone,’” Dr. Baldwin said. “And they want it gone yesterday. Few understand this is a long process. I tell them we’ll become extraordinarily good friends over the next 6-12 months while we get rid of this thing.” Moreover, it’s not possible to eliminate keloids without leaving a sign behind. “Most want it eradicated with normal skin,” but the skin beneath a keloid “will never look normal,” she observed.
The following are some tips for treating patients with keloids that she provided during her presentation:
- Surgery is usually not an option, and it may be necessary to convince patients about other treatment options. “Most don’t want corticosteroid injections, but that is how we treat them and keep them from coming back,” Dr. Baldwin said.
- Surgery may be appropriate in certain cases, such as keloids that are shaped like mushrooms and are attached to the skin via a stalk. Patient compliance with adjunctive therapy (injected corticosteroids) is crucial to prevent recurrence after surgery. Be aware that some patients – such as those who are afraid of needles – may refuse to return. Earlobes, a common site of keloids because of earrings, are a special case in surgery. Patients with earlobe keloids often fare well after surgery, Dr. Baldwin said, and recurrence is less common than in other parts of the body, especially when corticosteroids are added. It helps that patients are often more compliant with adjunctive therapy, she added, because the keloids are highly visible, and they want to wear earrings again.
- Ask patients what bothers them the most about the keloids. Some may want to eliminate burning, itching, or stinging, and Dr. Baldwin attempts to treat those issues. Patients may want keloids to be softer, flatter, or lighter, she said.
- Modification of the keloid’s appearance may be enough for some patients. For example, one of her patients objected to extensive keloids around his breasts because they gave him the appearance of cleavage. Another believed – accurately – that his keloid looked like male genitalia. Dr. Baldwin treated it with the keloid equivalent of castration (surgically removing its “testicles”) and circumcision of sorts (a flattening of its “glans penis” with corticosteroids). “It didn’t look pretty,” she said, “but it no longer looked offensive to him.”
- Many patients present with keloids on the chest, back, and deltoids, “which have to have been from acne, but you can’t actually see the pimples,” Dr. Baldwin said. In these cases, she may turn to isotretinoin. This is not for treatment of keloids, but is a preventive strategy to stop further lesions from appearing and causing more keloids, she explained.
- In addition to corticosteroids, other postsurgical options include freezing, interferon, pressure dressings, dextran hydrogel scaffolding, and radiation therapy.
Moving forward, researchers “are looking at biologics, TNF-alpha inhibitors, and tyrosine kinase inhibitors in hopes that we can find something that will stop the incessant forward movement of some of our keloid patients,” Dr. Baldwin noted.

AT SDEF LAS VEGAS DERMATOLOGY SEMINAR
AD update: New insight into pathogenesis, prevention, and treatments
LAS VEGAS – Recent research has provided a rare triple whammy in the world of atopic dermatitis (AD). Over the last few years, Linda F. Stein Gold, MD, said at Skin Disease Education Foundation’s annual Las Vegas Dermatology Seminar.
AD affects an estimated 7% of adults in the United States and 13% of children under aged 18 years, according to the National Eczema Association. An estimated one-third of the affected children (3.2 million) have moderate to severe disease.
New information about AD includes more information pinpointing the genetic link. Dr. Stein Gold, director of clinical research in the department of dermatology at the Henry Ford Health System, Detroit, pointed out that about 70% of patients with AD have a family history of atopic conditions.
Mutations in filaggrin appear to play a role in the development of AD, but a significant proportion of people with AD do not have evidence of filaggrin mutations and about 40% of people with defects never develop AD, she noted.
Emollients may be key to preventing AD. To explore the theory that defects on the skin barrier “might be key initiators of atopic dermatitis and possibly allergic sensitization,” investigators conducted a randomized controlled study of 124 babies at risk of AD in the United States and United Kingdom; parents of 55 babies applied emollients to their whole bodies from shortly after birth until 6 months while a control group used nothing (J Allergy Clin Immunol. 2014 Oct; 134[4]:818-23).
At 6 months, those in the emollient group were half as likely to have developed AD (relative risk, 0.50; P = .017).
Bleach baths have received attention on the AD prevention front. Dr. Stein Gold pointed to a 2017 systematic review and meta-analysis of five studies that found both bleach and water baths reduced AD severity. Bleach baths were effective but not more so than water baths (Ann Allergy Asthma Immunol. 2017 Nov;119[5]:435-40). Also, there was no difference in skin infections or colonization with Staphylococcus aureus between the two.
So are water baths just as good as bleach baths? “I’m not 100% sure I buy into this,” Dr. Stein Gold said. “I’m still a bleach bath believer.”
Topical calcineurin inhibitors (TCIs) can be used as a “proactive,” steroid-sparing treatment to prevent relapses in AD, research suggests. For this purpose, the recommended maintenance dosage is two to three applications per week on areas that tend to flare; the TCI drugs can be used in conjunction with topical corticosteroids (J Am Acad Dermatol. 2014 Jul;71[1]:116-32).
TCIs come with boxed warning because of concerns about such cancers as lymphoma. But recent research has not found a higher risk of lymphoma in patients with AD who are treated with the medication. “We’ve had these drugs for a long time, and they do appear to be safe,” Dr. Stein Gold said.
She referred to a 2015 review of 21 studies of almost 6,000 pediatric patients with AD who were treated with a TCI, which concluded that the drugs are safe and efficacious over the long term (Pediatric Allergy Immunol. 2015 Jun;26[4]:306-15).
“Everyone wants to know which ones are better,” Dr. Stein Gold said in regard to TCIs. But there aren’t head-to-head studies, she said, and it’s difficult to compare the available data on response rates between certain topical treatments because the studies are designed differently.
For example, with crisaborole (Eucrisa), the topical phosphodiesterase-4 (PDE4) inhibitor approved in 2016 for mild to moderate AD in patients aged 2 years and up, clear/almost clear rates are 49%-52%, compared with 30%-40% with placebo, a 10%-20% difference. Rates with OPA-15406, an investigational topical selective PDE4 inhibitor, and with the TCI pimecrolimus (Elidel cream 1%) have been about 20% higher than with controls, but studies are designed differently, and the results cannot be compared, according to Dr. Stein Gold.
Dupilumab (Dupixent), a monoclonal antibody that inhibits signaling of both interleukin-4 and interleukin-13, approved in 2017 for adults with moderate to severe AD, has been a “game changer” for this population, Dr. Stein Gold said. “It looks like this drug has a good, durable effect,” she added (Lancet. 2017 Jun 10;389[10086]:2287-303).
However, she cautioned that up to 10% of patients treated with dupilumab – or more – may develop conjunctivitis. Researchers studying dupilumab in asthma have not seen this side effect, she said, so it may be unique to AD. “It’s something that’s real,” she said, noting that it’s not clear if it’s viral, allergic, or bacterial. Researchers are exploring the use of the drug in children, she added.
Dr. Stein Gold said there are other drugs in development for AD, but she cautioned that “the field is crowded ... and not all of them are going to make it.”
Drugs in development for AD include nemolizumab (a humanized monoclonal antibody that inhibits interleukin-31 signaling), upadacitinib (a JAK1 selective inhibitor), baricitinib (an oral JAK1/2 inhibitor), and topical tapinarof (an agonist of the aryl hydrocarbon receptor).

LAS VEGAS – Recent research has provided a rare triple whammy in the world of atopic dermatitis (AD). Over the last few years, Linda F. Stein Gold, MD, said at Skin Disease Education Foundation’s annual Las Vegas Dermatology Seminar.
AD affects an estimated 7% of adults in the United States and 13% of children under aged 18 years, according to the National Eczema Association. An estimated one-third of the affected children (3.2 million) have moderate to severe disease.
New information about AD includes more information pinpointing the genetic link. Dr. Stein Gold, director of clinical research in the department of dermatology at the Henry Ford Health System, Detroit, pointed out that about 70% of patients with AD have a family history of atopic conditions.
Mutations in filaggrin appear to play a role in the development of AD, but a significant proportion of people with AD do not have evidence of filaggrin mutations and about 40% of people with defects never develop AD, she noted.
Emollients may be key to preventing AD. To explore the theory that defects on the skin barrier “might be key initiators of atopic dermatitis and possibly allergic sensitization,” investigators conducted a randomized controlled study of 124 babies at risk of AD in the United States and United Kingdom; parents of 55 babies applied emollients to their whole bodies from shortly after birth until 6 months while a control group used nothing (J Allergy Clin Immunol. 2014 Oct; 134[4]:818-23).
At 6 months, those in the emollient group were half as likely to have developed AD (relative risk, 0.50; P = .017).
Bleach baths have received attention on the AD prevention front. Dr. Stein Gold pointed to a 2017 systematic review and meta-analysis of five studies that found both bleach and water baths reduced AD severity. Bleach baths were effective but not more so than water baths (Ann Allergy Asthma Immunol. 2017 Nov;119[5]:435-40). Also, there was no difference in skin infections or colonization with Staphylococcus aureus between the two.
So are water baths just as good as bleach baths? “I’m not 100% sure I buy into this,” Dr. Stein Gold said. “I’m still a bleach bath believer.”
Topical calcineurin inhibitors (TCIs) can be used as a “proactive,” steroid-sparing treatment to prevent relapses in AD, research suggests. For this purpose, the recommended maintenance dosage is two to three applications per week on areas that tend to flare; the TCI drugs can be used in conjunction with topical corticosteroids (J Am Acad Dermatol. 2014 Jul;71[1]:116-32).

REPORTING FROM SDEF LAS VEGAS DERMATOLOGY SEMINAR
In pediatric ICU, being underweight can be deadly
SAN DIEGO – Underweight people don’t get much attention amid the obesity epidemic. But a new analysis of worldwide data finds that underweight pediatric ICU patients worldwide face a higher risk of death within 28 days than all their counterparts, even the overweight and obese.
While the report suggests that underweight patients weren’t sicker than the other children and young adults, they also faced a higher risk of fluid accumulation and all-stage acute kidney injury, compared with overweight children, study lead author Rajit K. Basu, MD, MS, of Emory University and Children’s Healthcare of Atlanta, said in an interview. His team’s findings were released at Kidney Week 2018, sponsored by the American Society of Nephrology.
“Obesity gets the lion’s share of the spotlight, but there is a large and likely growing population of children who, for reasons left to be fully parsed out, are underweight,” Dr. Basu said. “These patients have increased attributable risks for poor outcome.”
The new report is a follow-up analysis of a 2017 prospective study by the same team that tracked acute kidney injury and mortality in 4,683 pediatric ICU patients at 32 clinics in Asia, Australia, Europe, and North America. The patients, aged from 3 months to 25 years, were recruited over 3 months in 2014 (N Engl J Med 2017;376:11-20).
The researchers launched the study to better understand the risk facing underweight pediatric patients. “There is a paucity of data linking mortality to weight classification in children,” Dr. Basu said. “There are only a few reports, and there is a suggestion that the ‘obesity paradox’ – protection from morbidity and mortality because of excessive weight – exists.”
For the new analysis, researchers tracked 3,719 patients: 29% were underweight, 44% had normal weight, 11% were overweight, and 16% were obese.
The 28-day mortality rate was 4% overall and highest in the underweight patients at 6%, compared with normal (3%), overweight (2%), and obese patients (2%) (P less than .0001). Underweight patients had a higher adjusted risk of mortality, compared with normal-weight patients (adjusted odds ratio, 1.8; 95% confidence interval, 1.2-2.8).
Underweight patients also had “a higher risk of fluid accumulation and a higher incidence of all-stage acute kidney injury, compared to overweight children,” Dr. Basu said.
The study authors also examined mortality rates in the 14% of patients (n = 542) who had sepsis. Again, underweight patients had the highest risk of 28-day mortality (15%), compared with normal weight (7%), overweight (4%), and obese patients (5%) (P = 0.003).
Who are the underweight children? “Analysis of the comorbidities reveals that nearly one-third of these children had some neuromuscular and/or pulmonary comorbidities, implying that these children were most likely static cerebral palsy children or had neuromuscular developmental disorder,” Dr. Basu said. “The demographic data also interestingly pointed out that the underweight population was predominantly Eastern Asian in origin.”
But there wasn’t a sign of increased illness in the underweight patients. “We can say that these kids were no sicker compared to the overweight kids as assessed by objective severity-of-illness scoring tools used in the critically ill population,” he said.
Is there a link between fluid overload and higher mortality numbers in underweight children? “There is a preponderance of data now, particularly in children, associating excessive fluid accumulation and poor outcome,” Dr. Basu said, who pointed to a 2018 systematic review and analysis that linked fluid overload to a higher risk of in-hospital mortality (OR, 4.34; 95% CI, 3.01-6.26) (JAMA Pediatr. 2018;172[3]:257-68).
Fluid accumulation disrupts organs “via hydrostatic pressure overregulation, causing an imbalance in local mediators of hormonal homeostasis and through vascular congestion,” he said. However, best practices regarding fluid are not yet clear.
“Fluid accumulation does occur frequently,” he said, “and it is likely a very important and relevant part of practice for bedside providers to be mindful on a multiple-times-a-day basis of what is happening with net fluid balance and how that relates to end-organ function, particularly the lungs and the kidneys.”
The National Institutes of Health provided partial funding for the study. One of the authors received fellowship funding from Gambro/Baxter Healthcare.

Questions, documentation, and lab tests are crucial in alopecia areata
LAS VEGAS – according to Maria Hordinsky, MD, professor and chair of the department of dermatology at the University of Minnesota, Minneapolis.
Other important steps in the work-up of a patient include extensive documentation of AA – including use of the Severity of Alopecia Tool (SALT) score or photography – and laboratory testing, Dr. Hordinsky said at the Skin Disease Education Foundation’s annual Las Vegas Dermatology Seminar.
AA affects an estimated 1.7%-2.1% of the population and is sporadic in 50%-80% of cases. AA targets follicles in the anagen phase, which makes up 90% of hair follicles and normally lasts for 2-7 years. The condition has been linked to vitiligo, thyroid disease, and atopy (allergic rhinitis, asthma, and atopic dermatitis). AA has also been linked to autoimmune disorders, such as lupus erythematosus, psoriasis, rheumatoid arthritis, celiac disease, and type 1 diabetes mellitus. In addition, Dr. Hordinsky said, genetic research has linked alopecia to the latter three conditions.
It’s important to ask how much the hair loss bothers the patient, regardless of his or her age, Dr. Hordinsky said. “You need to figure out what’s making them all anxious and depressed. Is it shedding hair every single day?” she said. “Figure out what bothers that patient and go after that issue after you’ve answered his or her questions.”
In some cases, she said, “patients who’ve had extensive disease for a very long time are really coming in for a social visit to talk about what’s new, what’s emerging, whether they’d be interested in participating in a clinical trial.”
Dr. Hordinsky provided this list of questions to help in evaluating these patients:
- Is scalp hair loss the biggest problem? Eyebrow loss? Eyelash loss? Nail issues? All of these?
- How bothersome is it to experience hair shedding every day? Does this make the patient depressed and anxious?
Dr. Hordinsky added that asking patients about the following topics can also be appropriate:
- Hair care habits. Is the patient no longer shampooing because of hair loss?
- Medications.
- Symptoms, such as pain, itch, and burning.
- Body hair. Does the patient feel there’s too little or too much?
- Nail abnormalities.
- Menstrual cycle and pregnancies.
- Diet and supplements.
- Family history. Patients – who are often very curious about the disease – often mention relatives when they hear about a genetic role in AA, she said. They’ll say “My aunt has rheumatoid arthritis” or “My cousin has autoimmune disease.”
- Excess androgen levels and autoimmune/endocrine diseases.
The patient examination should include documentation of the presence of vellus hair or indeterminate and terminal fibers; the presence or absence of scale, erythema, folliculitis, and atrophy; eyebrow, eyelash, or body hair loss; and nail damage, such as pitting.
Photography and/or the SALT score may be used for documentation, she said. The SALT score is the only standardized method of assessment for AA, she said. The score is produced by a calculation that takes into account the amount of hair loss in the quadrants (right, left, front, back) of the scalp (J Am Acad Dermatol. 2018 Sep;79[3]:470-478.e3).
Laboratory tests are important, but there is no standard list, Dr. Hordinsky said. They are selected based on history and physical examination and can include thyroid function studies; heme and iron profiles, including serum ferritin and hemoglobin; and measurements of vitamin D, thiamine, zinc, and total protein. “We check nutrition labs particularly if a patient has been taking a lot of supplements, and we’re not sure where we’re at,” Dr. Hordinsky said.
Dermatologists may also order tests to measure non-cycle dependent hormones such as dehydroepiandrosterone sulfate (DHEAS), total/free testosterone, and antinuclear antibodies and other autoantibodies.

Dr. Hordinsky added that asking patients about the following topics can also be appropriate:
- Hair care habits. Is the patient no longer shampooing because of hair loss?
- Medications.
- Symptoms, such as pain, itch, and burning.
- Body hair. Does the patient feel there’s too little or too much?
- Nail abnormalities.
- Menstrual cycle and pregnancies.
- Diet and supplements.
- Family history. Patients – who are often very curious about the disease – often mention relatives when they hear about a genetic role in AA, she said. They’ll say “My aunt has rheumatoid arthritis” or “My cousin has autoimmune disease.”
- Excess androgen levels and autoimmune/endocrine diseases.
The patient examination should include documentation of the presence of vellus hair or indeterminate and terminal fibers; the presence or absence of scale, erythema, folliculitis, and atrophy; eyebrow, eyelash, or body hair loss; and nail damage, such as pitting.
Photography and/or the SALT score may be used for documentation, she said. The SALT score is the only standardized method of assessment for AA, she said. The score is produced by a calculation that takes into account the amount of hair loss in the quadrants (right, left, front, back) of the scalp (J Am Acad Dermatol. 2018 Sep;79[3]:470-478.e3).
Laboratory tests are important, but there is no standard list, Dr. Hordinsky said. They are selected based on history and physical examination and can include thyroid function studies; heme and iron profiles, including serum ferritin and hemoglobin; and measurements of vitamin D, thiamine, zinc, and total protein. “We check nutrition labs particularly if a patient has been taking a lot of supplements, and we’re not sure where we’re at,” Dr. Hordinsky said.
Dermatologists may also order tests to measure non-cycle dependent hormones such as dehydroepiandrosterone sulfate (DHEAS), total/free testosterone, and antinuclear antibodies and other autoantibodies.

LAS VEGAS – according to Maria Hordinsky, MD, professor and chair of the department of dermatology at the University of Minnesota, Minneapolis.
Other important steps in the work-up of a patient include extensive documentation of AA – including use of the Severity of Alopecia Tool (SALT) score or photography – and laboratory testing, Dr. Hordinsky said at the Skin Disease Education Foundation’s annual Las Vegas Dermatology Seminar.
AA affects an estimated 1.7%-2.1% of the population and is sporadic in 50%-80% of cases. AA targets follicles in the anagen phase, which makes up 90% of hair follicles and normally lasts for 2-7 years. The condition has been linked to vitiligo, thyroid disease, and atopy (allergic rhinitis, asthma, and atopic dermatitis). AA has also been linked to autoimmune disorders, such as lupus erythematosus, psoriasis, rheumatoid arthritis, celiac disease, and type 1 diabetes mellitus. In addition, Dr. Hordinsky said, genetic research has linked alopecia to the latter three conditions.
It’s important to ask how much the hair loss bothers the patient, regardless of his or her age, Dr. Hordinsky said. “You need to figure out what’s making them all anxious and depressed. Is it shedding hair every single day?” she said. “Figure out what bothers that patient and go after that issue after you’ve answered his or her questions.”
In some cases, she said, “patients who’ve had extensive disease for a very long time are really coming in for a social visit to talk about what’s new, what’s emerging, whether they’d be interested in participating in a clinical trial.”
Dr. Hordinsky provided this list of questions to help in evaluating these patients:
- Is scalp hair loss the biggest problem? Eyebrow loss? Eyelash loss? Nail issues? All of these?
- How bothersome is it to experience hair shedding every day? Does this make the patient depressed and anxious?

EXPERT ANALYSIS FROM SDEF LAS VEGAS DERMATOLOGY SEMINAR
How lovers, limes, and drug samples can plague your patients
MONTEREY, CALIF. – “Consort dermatitis” – when a patient is allergic to his or her partner. “Lime dermatitis” – when gin and tonics are the culprit. And “sample dermatitis” – when an unprescribed drug sample turns out to be the cause of a mysterious reaction.
Dermatologist Vincent DeLeo, MD, of the University of Southern California, Los Angeles, has seen them all. He provided insight about how to diagnose these unusual conditions at the Coastal Dermatology Symposium.
The following are a few unusual causes of dermatitis that he discussed:
- Romantic partners. A patient’s partner can be the cause of a reaction, as in the case of a 25-year-old woman who turned out to be allergic to her boyfriend’s cologne. In another case, a 50-year-old man had a 3-year history of recurrent dermatitis on his left arm and the left side of his chest. The cause was a mystery until it became clear that it was caused by exposure to hair dye, but not his. “He didn’t color his hair, but his wife did, and she always slept on that side of him,” Dr. DeLeo recalled. “When she stopped coloring her hair, his disease cleared.”
- Black henna. The dye known as “black henna,” or just “henna,” can cause reactions in adults (who use it as a hair dye or to decorate the skin) and children (who can be exposed to it with temporary tattoos). “Because henna typically produces a brown, orange-brown, or reddish-brown tint, other ingredients must be added to produce other colors, such as those marketed as ‘black henna’ and ‘blue henna,’ ” according to a Food and Drug Administration statement. “Even brown shades of products marketed as henna may contain other ingredients intended to make them darker or make the stain last longer on the skin. The problem? “The extra ingredient used to blacken henna is often a coal-tar hair dye containing p-Phenylenediamine, an ingredient that can cause dangerous skin reactions in some people,” the statement says. Dr. DeLeo said that one good rule of thumb is to consider a reaction to black henna if a patient acknowledges using a henna dye and their hair is any color but red. That’s a sign, he said, that they’re actually using black henna.
- Makeup applicators. Dr. DeLeo has seen two cases of patients with facial dermatitis who turned out to be allergic to thiuram, a component of rubber. Their skin was reacting to the rubber in some sponges used to apply makeup.
- Lime and sun exposure. Patients are impressed when Dr. DeLeo correctly guesses what they were drinking the previous weekend, because of their telltale blisters indicating a lime allergy. Noninflammatory blisters on the fingers or hyperpigmentation can be caused by touching the skin of a lime and then having subsequent exposure to ultraviolet light. It may take days for the blisters to appear, he noted. A weekend after mixing gin and tonics with lime, for example, a patient “may show up on Tuesday of the following week. The patient doesn’t always think of what they did over the weekend.”
- Liquid detergents. As a general rule, laundry detergents do not cause dermatitis, Dr. DeLeo said. “By the time that clothing is rinsed in your washer, there’s not enough left of anything on the clothing to cause a problem.” But there’s an exception: When people hand wash clothing with liquid detergents, such as Woolite. “It’s not the fragrance,” he said. “It’s the preservative in the detergent.”
- Unexpected nickel. Skin allergy to nickel is common, and the metal can lurk in unexpected places, as he discovered when he treated a Columbia University student who was “allergic to his tuba.” The tuba was made of brass, not nickel. But “the little things connecting the tubes to each other are alloy metals,” he said, including nickel.
- Drug samples. Dr. DeLeo recalled the case of a dermatology office administrator with a recurrent neck rash. Dermatologist after dermatologist failed to find the cause. Patch and photopatch testing turned up nothing. Then Dr. DeLeo asked her to bring in every skin product she was using. She returned with a large bag full of dermatologic samples, including Drithocreme (anthralin), which can be an irritant. None of the drugs were prescribed. “This is case of sample dermatitis,” which may occur among employees and family members of dermatologists, he said. “Always think of having patients bring in what they’re using,” he added, “because you can be surprised.”
