Comorbid obesity and history of diabetes are independently associated with poorer treatment response to biologics at 6 months: A prospective analysis in Corrona Psoriasis Registry.

BACKGROUND: Psoriasis is associated with comorbid systemic metabolic disease. OBJECTIVE: To assess possible associations of comorbid obesity, history of diabetes, hypertension, and hyperlipidemia with response to biologic treatment at 6 months among patients in CorEvitas' Psoriasis Registry. METHODS: Participants included 2924 patients initiating biologic therapy (tumour necrosis factor inhibitors [TNFi], interleukin [IL]-17i, IL-12/23i, or IL-23i) with baseline and 6-month follow-up visits available. Logistic regressions resulted in adjusted odd ratios (OR) and 95% confidence intervals (CI) for achievement of response in select outcomes for those with obesity and history of diabetes, hypertension, and hyperlipidemia relative to those without each. RESULTS: Overall, obesity reduced by 25% to 30% odds of achieving PASI75 (OR, 0.75; 95% CI, 0.64-0.88) and PASI90 (OR, 0.70; 95% CI, 0.59-0.81). History of diabetes reduced odds of achieving PASI75 by 31% (OR, 0.69; 95% CI, 0.56-0.85) and PASI90 by 21% (OR, 0.79; 95% CI, 0.63-0.98). Obesity was associated with lower response to TNFi and IL-17i classes. Independent of obesity, diabetes was associated with poorer outcomes when on IL-17i therapy and hypertension, to a lesser extent, when on the TNFi class. No significant associations were found in the hyperlipidemia group. LIMITATIONS: The study assessed only short-term effectiveness and small sample sizes limited the power to detect differences. CONCLUSION: Assessment of comorbid disease burden is important for improved likelihoods of achieving treatment response with biologics.

Proportions of Biologic Discontinuation Among Psoriasis Patients With Metabolic Comorbidities.

Background: Among psoriasis patients, the presence of metabolic comorbidities associates with poorer response to biologics. How the presence of comorbidity impacts treatment patterns with biologics is not fully understood. Methods: Adult patients in the CorEvitas Psoriasis Registry were included if they initiated biologic therapy between 5/2015-12/2019 and had a 6-month follow-up visit. The frequency of biologic discontinuations by 6-months were calculated by metabolic comorbidity status (current obesity and histories of hypertension [HTN], diabetes [DM], and hyperlipidemia [HLD]) for all patients and by drug class (tumor necrosis factor inhibitors [TNFi], interleukin-17i [IL-17i], and IL-23i or IL-12/23i). Results: Among the 2924 participants, discontinuations were more frequent in those with obesity (17%, P < .01) or DM (20%, P < .001) compared to those without these (13% and 14%, respectively). Discontinuations were similar for those with and without histories of HTN or HLD. Frequencies of discontinuation for each biologic class were: TNFi (26%), IL-17i (16%), and IL-23i or IL-12/23i (9%). Among TNFi initiators, the proportions of discontinuations were greater in the presence of obesity (30%, P < .05), DM (34%, P < .05), or HTN (34%, P < .01) compared to those without (22%, 24%, and 22%, respectively). Of the IL-23i or IL-12/23i initiators, discontinuations were more frequent in those with obesity (11%, P < .01) or with DM (13%, P < .05) compared to those without (7% and 8%, respectively). Discontinuations did not statistically differ between comorbidity groups in IL-17i initiators. Conclusion: Comorbid disease status, especially obesity and DM, should be assessed at biologic initiation as it may predict a less optimal clinical outcome.

Cardiometabolic multimorbidity is common among patients with psoriasis and is associated with poorer outcomes compared to those without comorbidity.

BACKGROUND: Associations between cardiometabolic multimorbidity and response to therapy in psoriasis are unknown. OBJECTIVE: Determine the associations of multimorbidity with response to biologic treatment in psoriasis patients. METHODS: CorEvitas Psoriasis Registry participants who initiated biologic therapy and had 6-month follow-up were stratified by 0, 1, 2+ comorbidities (diabetes, hypertension, hyperlipidemia). Adjusted odds ratios (95% CIs) were calculated overall and separately by biologic class (TNFi, IL-17i, IL-12/23i + IL-23i), to assess the likelihood of achieving response for the 1 and 2+ groups vs. 0. RESULTS: Of 2,923 patients, 49.5%, 24.7% and 25.8% reported 0, 1 and 2+ comorbidities, respectively. Overall, likelihood of PASI75 was 18% (OR = 0.82; 95%CI: 0.67, 1.00) and 23% (OR = 0.77; 95%CI: 0.63, 0.96) lower in those with 1 and 2+ comorbidities, respectively, vs. 0. In those who initiated IL-17i, odds of PASI75 and PAS90 were 34% (OR = 0.66; 95%CI: 0.48-0.91) and 35% (OR = 0.65; 95%CI: 0.47-0.91) lower in the 2+ multimorbidity cohort. No significant associations were found among users of TNFi or IL-12/23i + IL-23i groups in the multimorbidity group. LIMITATIONS: Patients may not be representative of all psoriasis patients. CONCLUSION: Multimorbidity in psoriasis may decrease the likelihood of achieving treatment response to biologic therapy and should be considered when discussing treatment expectations with patients.

Unilateral Distribution of Lichen Planus Pigmentosus-Inversus Unresponsive to Clobetasol and Hydroquinone.

Lichen planus pigmentosus-inversus (LPP-inversus) is a rare, pigmented variant of lichen planus of unknown etiology. This skin condition typically affects the intertriginous and flexural regions of the body bilaterally. We report an unusual case presentation with unilateral distribution of LPP-inversus in a woman originally from Nepal. The lesions developed rapidly over a three-month period and were recalcitrant to therapy with topical clobetasol and hydroquinone.
