“They come in with bags of topical products to show you what they’ve tried,” Dr. Han, associate professor of dermatology at Hofstra University, Hempstead, N.Y., said during the ODAC Dermatology, Aesthetic & Surgical Conference. “And you’re supposed to see this patient, talk to them, and counsel them in about 10 minutes. How do you make time to conduct an efficient psoriasis visit?”
Patients have a long-term battle to get clear, and spending a little longer on the initial visit “pays a lot of dividends,” he said. “Some of these patients are the most thankful patients in our practices, and it truly is gratifying” to see how much they can improve.
Questions about diet
Dr. Han said that psoriasis patients often ask him if, what, or how much they’re eating affects their disease. “But how do you counsel patients about diet when we’re not dietitians? We can at least give some guidance based on available data.”
He referred to a nationwide study of psoriasis patient-reported outcomes and dietary behaviors, which found that the percentage of patients who reported skin improvement was greatest after reducing intake of alcohol (53.8%); gluten (53.4%); and nightshade vegetables, such as tomatoes, potatoes, and peppers (52.1%); and after adding fish oil/omega-3 (44.6%), vegetables (42.5%), and oral vitamin D (41%). He noted that there is a threefold increased incidence of celiac disease in patients with psoriasis.
As for nightshade vegetables, intake leads to increased alkaloids, “which have been known to worsen bowel inflammation such as in IBD [inflammatory bowel disease], but there is a lack of controlled trials examining this in the overall psoriasis population,” Dr. Han said. The Mediterranean diet, he added, “is sensible, and adding olive oil to your diet seems to have a positive effect on ... PASI, while fish oil seems to reduce C-reactive protein.” The data on the effect of vitamin D supplements are mixed, he said.
A separate randomized study evaluated the impact of weight loss in overweight or obese patients with psoriasis, who had not achieved clearance after 4 weeks of systemic treatment. Significantly more of those in the dietary intervention arm reached the weight loss goal of 5% at 20 weeks, and patients in this arm had a median reduction in the Psoriasis Area and Severity Index (PASI) score of almost 50%, compared with almost 26% among those without an active dietary intervention.
Joint pain, PsA
For psoriasis patients who complain of joint pain, he recommends administering quick measures like the five-question Psoriasis Epidemiology Screening Test (PEST) to screen for psoriatic arthritis (PsA), which is available on the National Psoriasis Foundation web site. “I ask patients about swollen, tender joints – specifically hands, wrists, ankles, feet, and toes,” Dr. Han said. Joint stiffness in the morning is a “concerning finding,” which is “more indicative of psoriatic arthritis than vague knee or back pain that worsens with use. If you have a younger patient with back pain who has a reduced ability to flex their spine, think axial disease.”
Tumor necrosis factor (TNF)–alpha inhibitors are considered first- and second-line treatment for PsA, but interleukin (IL)–17 inhibitors are generally considered just as effective overall. “The IL-23 inhibitors have mixed signals,” said Dr. Han, who is also on the NPF’s medical board. “We know that guselkumab is effective against psoriatic arthritis, but there is no inhibition of joint progression at the approved dosage on the label – though it was pretty close.”
Risankizumab (Skyrizi), an IL-23 inhibitor, was approved in January 2022 for adults with PsA and while the American College of Rheumatology response data “look reasonably good, the results for inhibition of radiographic progression are quite far off and it’s not in the label,” he said. Tildrakizumab (Ilumya), an IL-23 inhibitor, “looks impressive in phase 2b trials. It will be interesting to see if there is differentiation between the IL-23 agents in treating joint disease going forward.”
Dr. Han considers biologic therapy a good option for patients with questionable joint involvement or very limited joint disease. “If the patient has some evidence of PsA, as long as it’s a medication that has approval for that, I’m OK with starting it,” he said. “However, for patients whose joint pain dominates over the skin, or [who] have severe joint disease at presentation, I would prioritize the TNF-alpha inhibitors and IL-17s and refer them to rheumatology for shared management.”
Topical, oral treatments
As for topical approaches to treating psoriasis, adding halobetasol propionate 0.01% to tazarotene 0.045% may have a synergistic effect, while tapinarof 1% cream holds promise, he said. Tapinarof, which is expected to be approved this year, is an investigative aryl hydrocarbon agonist that inhibits an array of proinflammatory cytokines, including interferon-gamma and TNF-alpha. “It has been shown to have inhibitory effects both on Th17 cytokines and Th2 cytokines,” Dr. Han said. “What’s nice about this is that patients still appear to have treatment effect 1-2 months after stopping the drug.”
Another topical agent now under FDA review for psoriasis, is roflumilast, a phosphodiesterase type 4 (PDE4) inhibitor, which has been shown to have a treatment efficacy of 30% or more. “We’ll see how this works into our treatment regimen for psoriasis,” he said, as strategies targeting PDE4 have already been reported to help treat psoriasis.
With regards to oral therapies, he said that there are concerns about the efficacy of the oral PDE4 inhibitor apremilast, approved for psoriasis, compared with other biologics. Deucravacitinib, an oral selective tyrosine kinase 2 (TYK2) inhibitor also under FDA review for psoriasis, “may fill this gap, because its efficacy seems much stronger and really capitalizes on blocking IL-23, which we know is a central pathway in the pathogenesis of psoriasis.”
Phototherapy is another treatment option. Home narrowband-UVB devices cost $3,000-$5,000, “which is a fraction of 1 year of biologic treatment,” Dr. Han said. Older data on phototherapy suggest that “lesions can clear within 2-3 months, depending on how often you do the phototherapy, while newer data suggest that 75% of patients can achieve clear or minimal disease” with phototherapy.
Biologic therapy
If patients meet criteria for treatment with a biologic, he begins the conversation by saying, “I don’t want to give you an immunosuppressant, but your psoriasis represents an overactivation of inflammation in your body, so in some way we have to bring that down. Ideally, we would target your immune system in a way that targets psoriasis very narrowly, while leaving it to do what it needs to: protecting against infections and neoplasia.”
XXXIL-17 inhibitors generally have the fastest onset of action, Dr. Han noted. Authors of a review paper found that achievement of Psoriasis Area and Severity Index (PASI) 50 was 1.8 weeks with brodalumab, 1.9 weeks for ixekizumab, 3 weeks for high-dose secukinumab, 3.5 weeks for adalimumab, 3.7 weeks for infliximab, 5.1 weeks for low-dose ustekinumab, 6.5 weeks for high-dose etanercept, and 10.9 weeks with low-dose etanercept, while achievement of PASI 50 was closer to 1 month for IL-23 inhibitors.
“The conversation I have with patients on IL-23 inhibitors is, ‘we’re in this for the long haul,’ otherwise they come in 2 months later,” he said. “They may have gotten clearer but we’re talking about getting well over half of our patients to PASI 100, or to clear or minimal disease, and they may not have gotten there yet. It helps to frame expectations.”
Dr. Han disclosed that he is a consultant to, a speaker for, or has received research support from Beiersdorf, CeraVe, Celgene, Janssen, Lilly, MC2, Pfizer, UCB, Boehringer Ingelheim, Bond Avillion, Athenex, Amgen, AbbVie, Regeneron/Sanofi, LEO Pharma, Ortho Dermatologics, BMS, Sun Pharma, Dermavant, Dermtech, MedX, Novartis, and Castle Biosciences.
