Although there are now two Food and Drug Administration (FDA)-approved treatments for severe alopecia areata (AA), many patients still resort to non-medical therapies and lifestyle modifications such as diet and nutrition. The goal of this study was to evaluate the sources and types of dietary and nutritional advice for patients with AA. We distributed a cross-sectional national survey using the National Alopecia Areata Foundation's email list-serv between August 2022 and January 2023. Most respondents were White (76.3%), employed (58.3%) females (84.4%) with a mean age of 52 years. 163 (19.1%) respondents reported receiving diet and/or nutritional advice and 418 (49.5%) respondents reported searching for diet and/or nutritional advice to help with their AA; the most common source of advice was online. The most common dietary changes were the use of vitamins or supplements (30.6%), adherence to diets (23.2%), and the addition of specific foods (21.4%). 209 (50.2%) respondents reported no change in their disease and 197 (47.4%) respondents reported no change in how they felt about their disease compared to before they tried the change. Many AA patients search for or receive unsolicited dietary and nutritional advice and subsequently modify their behavior to manage their disease. However, the efficacy of these changes is unclear. Providers should be mindful of the sources through which patients obtain treatment information as well as the lifestyle changes patients make to counsel patients with evidence-based information. Further investigation is needed to better characterize the direct and indirect costs of dietary and nutritional modification in the treatment of AA.

Biologics and Janus kinase (JAK) inhibitors are immunomodulating and immunosuppressing medications utilized to treat atopic dermatitis (AD), psoriasis (PSO), psoriatic arthritis (PsA), and alopecia areata (AA). Special recommendations must be considered when prescribing vaccinations in this population, as the pneumococcal and herpes zoster vaccine are recommended to patients ≥ 19-years-old (rather than ≥ 65-years-old and ≥ 50-years-old as in the general population, respectively), along with a yearly influenza and up to date COVID-19 vaccination. Additionally, TNF-α and JAK-inhibitors may increase the risk of latent Hepatitis B virus (HBV) reactivation among high-risk patients. Prior to prescribing these medications, a quantitative HepB Surface Antibody (HepB SA) test is performed to determine immunity. This study utilized the SlicerDicer function on EPIC Medical Records to search for any patient ≥ 19-years-old prescribed a biologic or JAK inhibitor for AD, PSO, PsA, or AA between 10/2003 and 10/2023 at a large tertiary institution. Vaccination rates among patients on biologics and JAK inhibitors were low, with rates being significantly lower in patients 19-64 years-old, compared to those ≥ 65 years-old for most disease states (p < 0.01). Among AD, PSO/PsA, and AA patients, on average, 9.39% were vaccinated for influenza, 6.76% for herpes zoster, 16.56% for pneumococcal pneumonia, and 63.98% for COVID-19. Only 3.16% of patients were adequately vaccinated for HepB after an abnormal HepB SA test. Here, extremely low rates of vaccination among patients on biologics and JAK inhibitors at our institution were highlighted, emphasizing the imperative need for ensuring vaccination in this group.

In the field of alopecia areata research, various focuses including risk factors, epidemiology, molecular pathways, and treatment were constantly improving. However, to date, a bibliometric analysis summarizing the research trend is not available to date. The main objective of this study was to provide researchers with an overview of the research trend on alopecia areata in the past two decades. In Web of Science database, screening and extraction of studies related to alopecia areata has been performed. Within studies related to alopecia areata, the most cited 100 studies were appraised and the information of articles, including the citation amounts, keywords and publication types, was extracted for analyses. On average, each study in the top 100 list was cited 104.72 times. Within the top 100 list, the most focused fields were on the management of alopecia areata (34%), molecular mechanisms (28%) and epidemiological issues (23%). Approximately one third of the management-associated studies focused on Janus kinase (JAK) inhibitors (10 studies) and 5 studies focused on the efficacy of corticosteroids for alopecia areata. According to the results of the keyword analysis, JAK inhibitors had become the most mentioned keywords in the field of alopecia areata research since 2016. The top 100 most referenced papers in the field of alopecia areata mostly focused on essential aspects such as treatment options, pathogenesis, risk factors, and comorbidities. The results of the current study could be considered a potential resource for future research and patient care information.

Alopecia areata (AA) is an autoimmune disease that develops due to inflammation and causes sudden hair loss. Ithas been observed that family circumstances may contribute to the development of AA. This study aims to assessthe relationship between the development of alopecia areata in children, family functions, and depression andanxiety levels in their parents.Thirty-nine participants diagnosed with AA and 41 healthy controls (HC), agedbetween 8 and 18 years, and their parents participated in the study. The assessment of the children included thecompletion of a socio-demographic data form, the Parenting Style Scale (PSS), and the Revised Children's Anxietyand Depression Scale (RCADS). The parents provided information on a sociodemographic form, the BeckDepression Inventory (BDI), and the Beck Anxiety Inventory (BAI). The children in the control group scoredsignificantly higher on the PSS acceptance/ involvement subscale than those with AA. In the AA group, the numberof authoritative and indulgent (PSS) families was statistically significantly lower than that of the families in the HC,and the number of neglectful families was statistically significantly higher than those of the control group. Totalanxiety and depression t scores (RCADS) were statistically significantly higher in the AA children than in theHC. Our study demonstrates the importance of considering familial factors and parental mental health tounderstand and address alopecia areata in children. Our findings support the psychosomatic component of AA.Implementing comprehensive treatment strategies that target psychological well-being and family dynamics couldprove crucial.

Much research has been conducted to determine how hair regeneration is regulated, as this could provide therapeutic, cosmetic, and even psychological interventions for hair loss. The current study focused on the hair growth effect and effective utilization of fatty oil obtained from Bryde's whales through a high-throughput DNA microarray approach in conjunction with immunohistochemical observations. The research also examined the mechanisms and factors involved in hair growth. In an experiment using female C57BL/6J mice, the vehicle control group (VC: propylene glycol: ethanol: water), the positive control group (MXD: 3% minoxidil), and the experimental group (WO: 20% whale oil) were topically applied to the dorsal skin of the mouse. The results showed that 3% MXD and 20% WO were more effective than VC in promoting hair growth, especially 20% WO. Furthermore, in hematoxylin and eosin-stained dorsal skin tissue, an increase in the number of hair follicles and subcutaneous tissue thickness was observed with 20% WO. Whole-genome transcriptome analysis also confirmed increases for 20% WO in filaggrin (), a gene related to skin barrier function; fibroblast growth factor 21 (), which is involved in hair follicle development; and cysteine-rich secretory protein 1 (), a candidate gene for alopecia areata. Furthermore, the results of KEGG pathway analysis indicated that 20% WO may have lower stress and inflammatory responses than 3% MXD. Therefore, WO is expected to be a safe hair growth agent.

Previous studies demonstrated that Th1 cytokines like IL-2, IL-12 and IFN-γ have initiatory role in alopecia areata (AA) and positive correlation with disease severity. They informed that serum levels of Th17 cytokines, IL-17, IL-22, IL-23 increased in active AA patients and corelated, particularly IL-17, with disease severity. In recent reports it was showed the balance between Th17 and Treg cells is crucial for maintaining tolerance to self-antigens, and an imbalance towards Th17 may contribute to the development of autoimmune diseases like AA. But research on serum Treg markers in AA is limited. It was aimed to investigate whether the Treg cells have a role in the pathogenesis of AA analyzing the serum levels of Treg cytokines IL-35 and TGF-β in the patients with AA. 42 AA patients and 38 healthy controls were enrolled. Patient demographics, clinical data, disease severity assessed by Severity of Alopecia Tool (SALT) scores were recorded. Serum samples were collected and analyzed for TGF-β and IL-35 levels using ELISA kits. The cytokine levels in both groups were statistically compared. Their relation with parameters of demographic and severity of disease was evaluated. The patient and control groups had no statistically significant difference, there was 71.4% males and 28.6% females in patient group, while the control group had 63.2% males and 36.8% females, Severity analysis classified 18 patients with mild AA, 19 with moderate AA, and 5 with alopecia totalis/areata universalis. While TGF-β levels exhibited no significant difference between groups, IL-35 levels were significantly elevated in AA patients (p = 0.002). Logistic regression identified IL-35 as a significant parameter influencing disease status (OR = 1.055). Correlation analysis revealed a weak positive correlation between patient age and IL-35 levels (r = 0.436; p = 0.004). Notably, IL-35 levels displayed a significant decrease in individuals with antinuclear antibody (ANA) positivity. No correlations were identified between cytokine levels and disease severity, prognosis, or disease activity. Elevated IL-35 levels suggest that IL-35 and specific Treg cell subsets can play a role in AA pathogenesis. The nuanced roles of TGF-β and IL-35 highlight the need for comprehensive studies to interpret their implications in the complex immunopathogenesis of AA. These findings open avenues for further research, positioning IL-35 as a prospective target for investigating and potentially intervening in AA pathogenesis.

JPMA. the Journal of the Pakistan... May 2024TTo investigate the level of interleukin-6 in alopecia areata patients.
OBJECTIVE
TTo investigate the level of interleukin-6 in alopecia areata patients.
METHODS
The exploratory study was conducted from September to December 2021 at the Sindh Institute of Skin Disease, Karachi, and comprised alopecia areata patients regardless of age and gender in group A, while healthy controls matched for age and gender formed group B. Alopecia areata classification and severity were done using the Severity of Alopecia Tool. Serum interleukin-6 was measured using enzyme-linked immune sorbent assay. Data was analysed using R statistical software v4.2.1.
RESULTS
Of the 100 subjects, 50(50%) with mean age 15.52±10.14 years were cases in group A; 26(52%) females with mean age 16.78±10.77 years, and 24(48%) males with mean age 16.44±10.3 years. The remaining 50(50%) were controls in group B. Interleukin-6 concentration was significantly higher in group A (p<0.05). The concentration was not significantly different between the genders (p>0.05). The concentration was the highest in patients aged 11-20 years, followed by 21-30 years, 31-40 years and 1-10 years.
CONCLUSION
The concentration of circulatory pro-inflammatory interleukin-6 was significantly higher in alopecia areata patients than in the healthy controls.
