Comorbid Conditions Associated with Alopecia Areata: A Systematic Review and Meta-analysis.

BACKGROUND: Alopecia areata (AA) is a complex autoimmune condition resulting in nonscarring hair loss. In recent years, many studies have provided new evidence on comorbid diseases present in patients with AA. However, some studies have conflicting results, and analyses conducting a comprehensive approach are lacking. OBJECTIVE: The aim of our study was to provide an updated systematic review and meta-analysis of medical comorbidities associated with AA. METHODS: We searched PubMed, Embase, and Web of Science for case-control, cross-sectional, and cohort studies investigating medical comorbidities in AA published from inception through 1 February 2023. RESULTS: We screened 3428 abstracts and titles and reviewed 345 full text articles for eligibility. Ultimately, 102 studies were analyzed, comprising 680,823 patients with AA and 72,011,041 healthy controls. Almost all included studies (100 of 102 studies) were of satisfactory to high quality (Newcastle-Ottawa scale score ≥ 4). Among patients with AA, comorbidities with the highest odds ratios (OR) compared with healthy controls and data available from more than one study included vitamin D deficiency (OR 10.13, 95% CI 4.24-24.20), systemic lupus erythematous (OR 5.53, 95% CI 3.31-9.23), vitiligo (OR 5.30, 95% CI 1.86-15.10), metabolic syndrome (OR 5.03, 95% CI 4.18-6.06), and Hashimoto's thyroiditis (OR 4.31, 95% CI 2.51-7.40). AA may be a protective factor for certain disorders, for which the AA group had lower odds compared with healthy controls, such as irritable bowel syndrome (OR 0.38, 95% CI 0.14-0.99) and colorectal cancer (OR 0.61, 95% CI 0.42-0.89). CONCLUSION: These findings corroborate and contextualize the risks across comorbidities for patients with AA. Further work should be done to identify the underlying pathophysiology and understand appropriate screening criteria.

The Effects of a Fasting Mimicking Diet on Skin Hydration, Skin Texture, and Skin Assessment: A Randomized Controlled Trial.

Diet and nutrition have been shown to impact dermatological conditions. This has increased attention toward integrative and lifestyle medicine in the management of skin health. Emerging research around fasting diets, specifically the fasting-mimicking diet (FMD), has provided clinical evidence for chronic inflammatory, cardiometabolic, and autoimmune diseases. In this randomized controlled trial, we evaluated the effects of a five-day FMD protocol, administrated once a month for three months, on facial skin parameters, including skin hydration and skin roughness, in a group of 45 healthy women between the ages of 35 to 60 years old over the course of 71 days. The results of the study revealed that the three consecutive monthly cycles of FMD resulted in a significant percentage increase in skin hydration at day 11 (p = 0.00013) and at day 71 (p = 0.02) relative to baseline. The results also demonstrated maintenance of skin texture in the FMD group compared to an increase in skin roughness in the control group (p = 0.032). In addition to skin biophysical properties, self-reported data also demonstrated significant improvement in components of mental states such as happiness (p = 0.003) and confidence (0.039). Overall, these findings provide evidence for the potential use of FMD in improving skin health and related components of psychological well-being.

The Impact of Hidradenitis Suppurativa on Health Care Decision Making and Vaccines.

Background: Hidradenitis suppurativa (HS) is a chronic skin disease that causes significant burden for patients in multiple aspects of their life. However, the details regarding the impact on factors aside from skin are limited. Objective: We explored patient perspectives around the impact of HS on personal health and how that affects a patient's health care decision making. Methods: Individual, semi-structured, virtual interviews were conducted with adults that have HS by a trained medical student. The interviews were performed over a private, video conference platform. English speaking individuals between the ages of 18-45 with a diagnosis of HS for at least 1 year were invited to participate in the study. The transcripts were coded by the medical student and a research assistant and discrepancies were resolved by group consensus. This study followed the reporting guidelines of the Consolidated Criteria for Reporting Qualitative Research. Results: 23 participants were interviewed in which 21 participants (91%) were female and 2 participants (9%) were male. The mean age was 31.2 years. Patients expressed an increased awareness of their personal health because of their HS, including considering HS with respect to what they ate, the medications they took, the physicians they sought, and their family planning decision. Some participants stated that HS made them more likely to receive vaccines while others described the two are unrelated. Conclusions: Patients with HS considered their skin disease when making medical decisions broadly. Many specifically considered their disease when making decisions regarding health maintenance and immunizations though some did not consider the two related.
