The Multi-Faceted Role of Gut Microbiota in Alopecia Areata

In this study, researchers using Mendelian randomization found a potential causal relationship between the gut microbiome and alopecia areata, with 16 gut microbial taxa showing links to the condition, though reverse causation results were not statistically significant.

This study found that patients with alopecia areata had a significantly different gut microbiota composition compared to healthy controls, suggesting possible microbiota involvement in the disease's pathogenesis.

This study found that individuals with Alopecia Areata had distinct gut microbiome characteristics, including reduced species richness and specific microbial biomarkers, suggesting a potential link with oxidative stress.

This review explores the connection between the gut-skin axis and the development of dermatological conditions like atopic dermatitis, psoriasis, alopecia areata, and acne, and discusses the potential of probiotics in reshaping the microbiome to alleviate these skin issues.

In this study, the researchers used Mendelian randomization to suggest a potential causal link between various gut microbiota and alopecia areata, finding that certain bacteria like Butyricimonas and Phascolarctobacterium may have protective effects, whereas others like Ruminococcaceae UCG003 might increase risk.

This review reports that alterations in the scalp, hair follicle, and gut microbiome are associated with alopecia, and interventions targeting microbiome dysbiosis may have potential in treating hair loss.

This review discusses the role of cutaneous and intestinal microbiota in the development of alopecia areata, summarizing current literature without reporting new clinical results.

JAK inhibitors show promise for treating alopecia areata, but more research is needed.

In this case report, an 86-year-old man experienced new hair growth and color change in alopecia areata after receiving fecal microbiota transplantation for noninfectious diarrhea.

This study found that alopecia areata is linked with a higher prevalence of systemic and psychiatric diseases, suggesting that physicians should monitor for these potential comorbidities.

This review discusses how modern lifestyle factors affecting gut health may contribute to Alopecia Areata in genetically predisposed individuals, reporting no new results but suggesting the need for long-term interventions.

This article reviews the epidemiology, clinical evaluation, and pathogenesis of alopecia areata and highlights recent advancements, but it does not report new clinical findings.

The gut microbiome affects the development of alopecia areata.

This study found that feeding aged mice a probiotic yogurt induced changes leading to thicker, healthier fur, suggesting a bacteria-triggered interleukin-10-dependent mechanism that mimics signs of youth and reproductive fitness.

This article reviews the characteristics, associations, and diagnostic criteria for alopecia areata and reports no new clinical findings; the authors note the disease's unpredictable course and variable prognosis.

In this study, oral administration of Lactococcus lactis strain H61 to senescence-accelerated mice was linked to reduced bone density loss, less skin ulcer incidence, and reduced hair loss, along with altered immune responses.

This study found that increasing dietary soy oil content reduced alopecia areata development in C3H/HeJ mice, though genistein injection showed no significant effect.
