As a result, there has been increased focus on the development of precision medicine approaches for psoriasis and AD. Two companies at the forefront of dermatology precision medicine research are Mindera Health and Castle Biosciences. Here, we review the technologies developed by these two companies using a dermal diagnostic patch and superficial skin scrapings, respectively, their research published to date, and their future research goals. Research from both companies shows promise in predicting the response of inflammatory skin disease to biologics using minimally invasive techniques. However, challenges to adoption include insurance coverage and patient trust in the technologies. While there are several differences between Mindera Health and Castle Biosciences, they have a shared goal of utilizing minimally invasive technologies to sample skin and predict response to biologic treatments using a panel of optimized biomarkers.Keywords: machine learning, genetics, technology, diagnosis

INTRODUCTION: Psoriasis, a chronic inflammatory skin condition, affects approximately 3.0% of the US population, with patients often experiencing significant sleep disturbances. These disturbances include a higher prevalence of conditions such as obstructive sleep apnea, restless leg syndrome, and insomnia. Given the additional risks for cardiovascular disease, metabolic disorders, and depression linked to both poor sleep and psoriasis, addressing sleep issues in this patient group is critical. METHODS: The study utilized National Health and Nutrition Examination Survey (NHANES) data, focusing on individuals aged ≥ 20 years who provided information on psoriasis status and sleep. Multistage stratified survey methodology was applied, with multivariable logistic regression models used to examine the association between psoriasis and sleep issues, adjusting for factors such as age, gender, and health history. RESULTS: Psoriasis diagnosis was significantly associated with trouble sleeping (adjusted odds ratio [aOR] 1.88; 95% confidence interval [CI] 1.44-2.45). There was no significant association between psoriasis and sleep quantity. Older age, female gender, and a history of sleep disorders were predictors of trouble sleeping among psoriasis patients. CONCLUSIONS: Psoriasis is significantly associated with sleep disturbances, independent of sleep duration. This underscores the need for clinical screening focusing on sleep quality rather than quantity in psoriasis patients to effectively identify and treat sleep-related comorbidities. Further research using objective sleep measures is warranted to guide clinical management and improve patient quality of life.

BACKGROUND: Adherence to a Mediterranean Diet (MeD) has been associated with lower disease severity in patients with psoriasis. However, the mechanism behind how this diet may lead to disease modification remain understudied. Recent studies have revealed dysbiosis of the gut microbiome in patients with psoriasis suggestive of inflammation and altered immune regulation. Diet affects the gut microbiome and this review aims to evaluate whether correcting this dysbiosis may be one theoretical mechanism by which the MeD may be associated with lower psoriasis severity. METHODS: A literature search of the PubMed database was conducted for the terms 1) psoriasis and microbiome or microbiota, and 2) Mediterranean diet and microbiome or microbiota with manual screening for relevant articles. In total, we identified 9 relevant primary research studies investigating the gut microbiome in patients with psoriasis and 16 relevant primary research studies investigating changes in the microbiota for those consuming a MeD. RESULTS: Though varying in exact levels of certain bacteria, studies analyzing the microbiome in psoriasis revealed dysbiosis. Those analyzing the effect of the Mediterranean diet on the microbiome revealed beneficial changes, including alleviating some of the same alterations seen in the microbiome of those with psoriasis. CONCLUSION: Microbiota change is a possible mechanism why the MeD has previously been associated with lower psoriasis severity.

Pyoderma gangrenosum (PG) is a rare, difficult-to-treat neutrophilic ulcerative cutaneous condition that severely impacts those affected. Treatment options for PG are limited, and disease remission is not guaranteed. Hyperbaric oxygen treatment is a potential therapeutic option for treating various ulcerative conditions not frequently utilized for PG. We present a case of a patient with treatment-resistant PG who achieved remission with adjunctive HBOT, and then later had difficulty achieving remission without HBOT during a future flare. HBOT should be more readily considered as a treatment option for those with PG. • Pyoderma gangrenosum (PG) is a rare, often debilitating ulcerative cutaneous condition that can be very difficult to treat. • Hyperbaric oxygen treatment (HBOT) can promote wound healing and is utilized for several conditions involving tissue injury. • We present a case of a patient with refractory PG who had successful wound healing by adding HBOT as an adjunctive measure. • HBOT should be considered as a potential treatment option for PG.

Background: Repository corticotropin injection (RCI) has regulatory approval for many indications, including symptomatic sarcoidosis. This large case series of patients with advanced symptomatic sarcoidosis treated with RCI describes patient characteristics, RCI utilization patterns, concomitant therapies, and physicians’ assessments of treatment response. Methods: Patients ⩾18 years with symptomatic sarcoidosis, treated with RCI in the previous 36 months, who had completed a course of RCI or received RCI for ⩾6 months at the time of data collection were included. Results: The study included 302 patients (mean age, 51 years; 52%, women) with a mean 4.8 years since initial diagnosis of sarcoidosis. Most patients (76%) had extrapulmonary involvement, primarily in the skin (28%), joints (25%), heart (22%), and eyes (22%); 34% had multiple (⩾2) organ involvement. The mean duration of RCI treatment was 32.5 weeks, with 61.6% of patients continuing RCI therapy for ⩾6 months. The RCI utilization pattern indicated an individualized approach to therapy, with a higher starting dose associated with a shorter duration of therapy compared with a lower starting dose. The percentage of patients who used corticosteroids decreased from 61.3% during the 3 months before initiation of RCI to 12.9% 3 months after RCI therapy; the mean daily dose of corticosteroid decreased from 18.2 mg to 9.9 mg. The proportion of patients given

The article discusses the influence of lifestyle factors, particularly diet, on psoriasis severity and management. Topics include the potential benefits of dietary patterns like the Mediterranean diet and vegan/vegetarian diets in reducing systemic inflammation, improving gut health, and decreasing the risk of cardiometabolic comorbidities associated with psoriasis.

Hereditary alpha tryptasemia (HaT), an autosomal dominant condition first described in 2014, has previously been associated with multiple dermatologic, allergic, gastrointestinal, neuropsychiatric, autonomic, and connective tissue abnormalities. We describe a pediatric patient with predominantly mixed cutaneous inflammatory manifestations and atopic manifestations resistant to treatment who was found to have HaT. HaT should be considered in individuals with refractory inflammatory dermatologic disease and signs and/or symptoms concerning for mast cell activation. [ABSTRACT FROM AUTHOR]

Hereditary alpha tryptasemia (HaT) is a recently identified disorder that is associated with dermatologic manifestations such as urticaria, flushing, pruritus, and atopic dermatitis (AD), as well as a broad range of other symptoms affecting multiple systems. Given the potential cutaneous manifestations and the fact that dermatologic symptoms may be the initial presentation of HaT, awareness and recognition of this condition by dermatologists are essential for diagnosis and treatment. This review aims to summarize cutaneous presentations consistent with HaT and various conditions that share overlapping dermatologic symptoms with HaT. [ABSTRACT FROM AUTHOR]

This document is a comment on a study published in the British Journal of Dermatology regarding the impact of dupilumab treatment on sleep in patients with atopic dermatitis (AD). The authors of the comment note that while the study found subjective improvement in sleep parameters with dupilumab treatment, objective measures of sleep did not show the same improvement. They suggest that this discrepancy may be due to different dimensions of sleep being captured by subjective and objective measures. The authors also discuss the potential implications of chronic sleep impairment and suggest future studies to further investigate objective sleep quality in patients with AD.

Introduction: Repository corticotropin injection (RCI) has immune-modulatory and anti-inflammatory effects and is approved for multiple indications, including severe and acute chronic allergic and inflammatory processes involving the eye and adnexa. This study describes patient characteristics, treatment patterns, and physicians' assessments of patients with uveitis treated with RCI.Methods: This was a retrospective medical record review of US patients. Eligible patients had a diagnosis of uveitis, received RCI in the past 12 months, and had completed or were receiving RCI treatment at the time of data collection. Baseline characteristics and after-treatment clinical data are descriptively reported.Results: The study included 91 patients (mean age 41 years, 62% female, and mean time since diagnosis 3.98 years). Most patients had moderate (n = 48, 53%) to severe (n = 21, 23%) visual impairment, and none was blind before RCI therapy. Patients used an average of 2.5 medications before RCI. Initial RCI dosing regimens, dose adjustments, and treatment durations were different for each patient. Concomitant medication use and dosages were reduced during RCI; 76 patients (84%) improved, 15 patients (16%) stayed the same, and none worsened; 86% of patients had improvements in vision.Conclusions: Physicians individualized RCI therapy among patients who suffered uveitis for several years and when previous therapies were inadequate. Most patients improved after initiating RCI, most commonly in vision. The findings support use of RCI for uveitis and provide a better understanding of patient characteristics and practice patterns to guide appropriate use. [ABSTRACT FROM AUTHOR]
