Re-excision unnecessary in moderately dysplastic nevi with positive margins
ORLANDO – Re-excisions are not needed when clinically excised moderately dysplastic nevi have positive histologic margins, based on results of a retrospective study of 438 patients who were treated at nine academic medical centers in the United States.
Not a single patient in the study developed melanoma at the excision site after an average follow-up of 6.9 years, and at least 3 years in all cases, said Elizabeth G. Berry, MD, of Emory University, Atlanta, and Atlanta Veterans Administration Medical Center, one of the study investigators.
The finding “really has the potential to change how we manage these lesions. You don’t need to cut [these patients] again. You can watch them. Close observation with routine skin surveillance is reasonable,” Dr. Berry said at the International Investigative Dermatology meeting.
Routine skin exams are essential for patients with a history of dysplastic nevi as these patients are at risk for developing melanoma. Indeed, in this study, 100 patients (22.8%) subsequently developed melanomas at a site other than the location of their biopsy.
The study included 438 patients who had 467 biopsies that indicated incomplete excision of a moderately dysplastic nevus from 1990 to 2014. Patients were at least 18 years old and were an average of 47 years old. About half had a history of dysplastic nevi, and a third had a history of melanoma.
All of their biopsies for moderately dysplastic nevi had positive margins, but patients had no clinically apparent residual pigment at their excision sites. Lesions were equally as likely to be removed by shave and punch biopsies, and the majority of the nevi were located on the trunk. Complete excision was the intent in all cases.
To control for interobserver variability, the centers submitted a total of 40 slides for central dermatopathology review, which found agreement in 35 cases (87.8%). Two of the remaining five cases were downgraded to mild dysplasia, two were upgraded to severe, and one patient was upgraded to melanoma in situ, but hasn’t had a recurrence after 5 years of follow-up.
Controlling for age, sex, and family history, a patient history of dysplastic nevus prior to the biopsy doubled the risk of a subsequent melanoma (P = .017), and a history of melanoma increased it almost eightfold (P less than .001).
Knowing these risk factors, patients with a history of dysplastic nevi “need to have more frequent total body skin exams. What that frequency is, we don’t know,” Dr. Berry said.
The investigators reported they had no relevant disclosures.

Adalimumab strikes out for aortic inflammation in psoriasis
ORLANDO – Adalimumab (Humira) did not reduce aortic inflammation in a year-long, randomized trial that pitted the tumor necrosis factor (TNF) blocker against phototherapy and placebo in 97 psoriasis patients.
Joel M. Gelfand, MD, a dermatology professor at the University of Pennsylvania, Philadelphia.
The other trial, from Canada, also found no effect in the ascending aorta after 52 weeks of treatment, but it did find a modest increase in carotid inflammation (J Invest Dermatol. 2017 Aug;137[8]:1638-45).
Both studies used positron emission tomography/computed tomography to assess vascular inflammation.
“We know patients with psoriasis are at increased risk for cardiovascular disease. We think the same kind of inflammation that occurs in atherosclerosis occurs in psoriasis, but we are still teasing out the impact of therapy and which one is most likely to lower the risk of heart attacks, strokes, and things of that nature,” Dr. Gelfand said at the International Investigative Dermatology meeting. The study was published when he gave his presentation (Circ Cardiovasc Imaging. 2018 Jun. doi: 10.1161/CIRCIMAGING.117.007394).
Although it didn’t reduce aortic inflammation, adalimumab had a positive effect on glycoprotein acetylation, a marker of inflammation and subclinical cardiovascular disease in psoriasis. Observational studies have also reported a drop in cardiovascular events with adalimumab. Taken together, the mixed findings “give us pause for thought,” Dr. Gelfand said.
In a previous trial, he and his colleagues had found that the interleukin blocker ustekinumab (Stelara) reduced aortic inflammation in psoriasis by about 19%, but Dr. Gelfand said at the meeting that it’s too early to opt for ustekinumab over adalimumab for cardiovascular protection: “I don’t think we are quite there yet; we are still not certain.”
Following washout of psoriasis treatments, the 97 subjects were randomized to either adalimumab for 12 months or ultraviolet B phototherapy or placebo for 12 weeks, followed by adalimumab for 12 months.
Aortic inflammation was used as a proxy for cardiovascular events because trials to assess actual event rates would require thousands of patients treated for several years. “They’re not likely to be done in psoriasis any time soon,” Dr. Gelfand said.
At both 12 and 52 weeks, adalimumab patients had no change in aortic inflammation, compared with placebo and baseline. Phototherapy patients had a 4% drop from baseline at 12 weeks, but it was not statistically significant when compared with placebo.
Both adalimumab and phototherapy decreased systemic inflammation as gauged by serum C-reactive protein and interleukin-6 levels, but only adalimumab reduced TNF levels and glycoprotein acetylation at 12 and 52 weeks. Neither treatment affected insulin, adiponectin, or leptin levels. Adalimumab dropped HDL cholesterol a bit, a known side effect, while phototherapy increased it.
About half of the patients in both treatment arms had a 75% reduction in the Psoriasis Area and Severity Index at 12 weeks, compared with 7% of those on placebo. Subjects were aged 43 years, on average, and more than two-thirds were men. They had a mean psoriasis duration of 17 years and a baseline PASI score of 19.
The work was funded by the National Institutes of Health and AbbVie, adalimumab’s maker. Among many industry ties, Dr. Gelfand is a consultant for Janssen, maker of ustekinumab, and receives research grants from Janssen and AbbVie.

Regular skin exams reduced advanced KCs in posttransplant patients
ORLANDO – Annual skin exams reduced the rate of advanced keratinocyte carcinoma (KC) after solid organ transplant by 34%, according to a review of 10,198 transplant patients in Ontario, Canada.
Transplant patients have a far higher risk of KC than the general public because of immunosuppression: A quarter of patients are affected within 5 years. Transplant guidelines have recommended annual skin exams.
But just 2.1% of the patients in the review had annual exams, and less than half saw a dermatologist even once during an average of 5 years of follow-up.
Other studies have reported adherence rates of up to 50%, but the numbers were based largely on patient self-report. Instead, the Ontario study used billing codes and other administrative data to get an idea of how many patients actually followed through.
“I would be surprised if other jurisdictions have significantly better rates of adherence,” said lead investigator An-Wen Chan, MD, of the division of dermatology at the University of Toronto and director of a transplant dermatology clinic at the University Health Network.
Part of the problem is that there’s just not a lot of evidence that annual screenings improve KC outcomes, he noted.
To help plug that evidence gap, Dr. Chan and his team reviewed transplant cases in Ontario going back to the mid-1990s; 62% of the patients had kidney transplants, 24% had liver transplants, and the rest had heart or lung transplants. The patients were all aged over 18 years; 60% were white, 15% Asian, 4% black, and the rest unknown. About two-thirds were men.
Adherence to annual dermatology checkups at least 75% of the time was associated with a marked reduction in the development of advanced KC, defined as lesions greater than 2 cm and requiring reconstruction and lymphadenectomy (adjusted hazard ratio, 0.66; 95% CI, 0.48-0.92).
Increasing age at transplant, white race, male sex, and past history of skin cancer were among the factors that were associated with increased risk. There was a trend toward increased risk with liver, lung, and heart transplants, as opposed to kidney transplants. Results were adjusted for demographic, transplant, and other variables.
In short, “adherence to annual dermatology assessments ... reduced KC-related morbidity and death. The highest risk patients were not necessarily the ones that saw their dermatologist annually,” Dr. Chan said.
Rates of adherence varied across transplant sites. It’s probably less of a problem at the University of Toronto, where Dr. Chan is embedded with the transplant team and where he can educate patients and providers on the importance of annual screening and help ensure that it’s done.
“We have a rigorous skin referral policy in place and really target transplant patients to be seen within a year. Having a dermatologist dedicated to transplant dermatology really helps,” he said. The next step is to define the optimal frequency of posttransplant skin cancer screening and to address barriers to screening.
There was no industry funding for the work, and Dr. Chan had no relevant disclosures.

CBC values linked to CVD risk in psoriasis
ORLANDO – conducted by researchers at Case Western Reserve University, Cleveland.*
It’s generally accepted that psoriasis increases the risk of cardiovascular disease (CVD), but it’s not clear who’s most at risk. “We really wanted to find something that is cheap and easy to risk stratify these patients” said lead investigator Rosalynn Conic, MD, of Case Western’s department of dermatology.
Red blood cell distribution width (RDW) – a measure of the range of red blood cell volumes in a given sample – and mean platelet volume (MPV) fit the bill. In many places, they are already routinely reported on CBCs, so there’s no need for any special equipment or tests. Meanwhile, RDW and MPV elevations have been previously linked to CVD risk in the HIV and cardiology literature. The investigators wondered if they’d find a similar association in psoriasis, so they queried nearly 40,000 patients in the Explorys electronic health record database.
What they found was “very impressive, for sure,” Dr. Conic said at the International Investigative Dermatology meeting.
The incidence of MI was highest among the 1,920 patients (5%) with elevated RDW and MPV (odds ratio, 3.4; 95% confidence interval, 2.7-4.2; P less than .001), followed by the 7,060 (18%) patients with high RDW and normal MPV (OR, 2.4; 95% CI, 2.1-2.8; P less than .001), as compared with normal/low MPV and RDW patients.
Elevated RDW or elevated RDW plus MPV increased the odds of atrial fibrillation, coronary artery disease, heart failure, and peripheral vascular disease anywhere from 2 to 8.3 times (P less than .001). Among psoriatic arthritis patients, elevated RDW almost doubled the risk of MI (OR, 1.8; P less than .001). Results were adjusted for age, gender, and hypertension.
In a subanalysis of treatment effects, 4 of 23 psoriasis patients at Case Western had elevated RDWs at baseline. Values normalized in the three patients who achieved a 75% reduction in the Psoriasis Area and Severity Index score after about a year of systemic treatment.
“We aim to validate [the study results] with a Veterans Administration data set,” Dr. Conic said. If it pans out, “one use would be to send [patients with elevated values] to a cardiologist earlier” so other CVD risk factors can be monitored and treated. The findings also add to the case for good control, she noted.
Systemic inflammation is the common denominator between the blood value elevations and CVD. The same inflammatory cytokines that cause skin problems in psoriasis also stimulate bone marrow to release immature red blood cells, which are larger than mature cells, leading to an increased RDW. Similarly, elevated MPV indicates a higher number of larger, younger platelets in the blood.
“It’s probably something along those lines, but I think we need to go back to basic science and really figure it out,” Dr. Conic said.
Patients were 18-65 years old. The study excluded patients with diabetes, Crohn’s disease, RA, and generalized atherosclerosis.
The National Institutes of Health funded the work. Dr. Conic reported no relevant financial disclosures.

“We aim to validate [the study results] with a Veterans Administration data set,” Dr. Conic said. If it pans out, “one use would be to send [patients with elevated values] to a cardiologist earlier” so other CVD risk factors can be monitored and treated. The findings also add to the case for good control, she noted.
Systemic inflammation is the common denominator between the blood value elevations and CVD. The same inflammatory cytokines that cause skin problems in psoriasis also stimulate bone marrow to release immature red blood cells, which are larger than mature cells, leading to an increased RDW. Similarly, elevated MPV indicates a higher number of larger, younger platelets in the blood.
“It’s probably something along those lines, but I think we need to go back to basic science and really figure it out,” Dr. Conic said.
Patients were 18-65 years old. The study excluded patients with diabetes, Crohn’s disease, RA, and generalized atherosclerosis.

It’s generally accepted that psoriasis increases the risk of cardiovascular disease (CVD), but it’s not clear who’s most at risk. “We really wanted to find something that is cheap and easy to risk stratify these patients” said lead investigator Rosalynn Conic, MD, of Case Western’s department of dermatology.
Red blood cell distribution width (RDW) – a measure of the range of red blood cell volumes in a given sample – and mean platelet volume (MPV) fit the bill. In many places, they are already routinely reported on CBCs, so there’s no need for any special equipment or tests. Meanwhile, RDW and MPV elevations have been previously linked to CVD risk in the HIV and cardiology literature. The investigators wondered if they’d find a similar association in psoriasis, so they queried nearly 40,000 patients in the Explorys electronic health record database.
What they found was “very impressive, for sure,” Dr. Conic said at the International Investigative Dermatology meeting.
The incidence of MI was highest among the 1,920 patients (5%) with elevated RDW and MPV (odds ratio, 3.4; 95% confidence interval, 2.7-4.2; P less than .001), followed by the 7,060 (18%) patients with high RDW and normal MPV (OR, 2.4; 95% CI, 2.1-2.8; P less than .001), as compared with normal/low MPV and RDW patients.
Elevated RDW or elevated RDW plus MPV increased the odds of atrial fibrillation, coronary artery disease, heart failure, and peripheral vascular disease anywhere from 2 to 8.3 times (P less than .001). Among psoriatic arthritis patients, elevated RDW almost doubled the risk of MI (OR, 1.8; P less than .001). Results were adjusted for age, gender, and hypertension.
In a subanalysis of treatment effects, 4 of 23 psoriasis patients at Case Western had elevated RDWs at baseline. Values normalized in the three patients who achieved a 75% reduction in the Psoriasis Area and Severity Index score after about a year of systemic treatment.
