This study suggests that the role of vitamin 25(OH)D in the pathogenesis of PCOS and diminished ovarian reserve may be independent of serum vitamin 25(OH)D levels.

This case study reported on a 3-year-old child with vitamin D-dependent rickets type II treated in the Gaza Strip, whose condition deteriorated despite vitamin D and calcium treatments, leading to recurrent chest infections, respiratory failure, and eventual death.

This study assessed vitamin D levels in both serum and hair among 80 male and female participants from a dermatology clinic and found no significant gender-related differences in these vitamin D levels.

This study observed that individuals with autoimmune thyroid disease in Georgia had significantly higher frequencies of certain symptoms and Anti-TPO levels compared to controls, with no significant difference in vitamin D levels.

Vitamin D is crucial for skin health and managing skin diseases.

This article reviews the potential role of vitamin D supplementation as an adjunct to alemtuzumab therapy in multiple sclerosis management, noting its possible benefits for autoimmune comorbidities and patient adherence, but reports no new clinical results.

This study observed that low serum ferritin and vitamin D levels may contribute to diffuse hair loss in women.

This study highlighted knuckle hyperpigmentation as an early sign of vitamin B12 deficiency, indicating a potential link to megaloblastic anemia in the vegetarian population in India.

This study found that there was a significant discrepancy between histopathological examination and clinical diagnosis in alopecia cases, while vitamin D levels were not significantly associated with alopecia.

This study found that vitamin C deficiency in neonatal dairy calves is closely associated with skin problems like dermatosis, but treatment with vitamin C led to improvements.

This study investigates the relationship between vitamin B12 levels and chronic telogen effluvium, reporting that the role of vitamin B12 in its pathogenesis remains unclear.

The levels of zinc, vitamin D, ferritin, and selenium are different in people with androgenic alopecia compared to a control group.

This study observed that Egyptian patients with discoid lupus erythematosus have significantly lower serum vitamin D3 and antioxidant levels compared to healthy controls, suggesting potential benefits of vitamin D3 and antioxidant supplementation.

This study found that patients with telogen effluvium had significantly lower serum ferritin levels compared to healthy controls, suggesting a relationship between telogen effluvium and decreased iron stores.

This study found that 66% of patients with hair loss also have vitamin D deficiency, with a significantly higher prevalence among women than men.

This study suggests a link between hair loss experienced during pregnancy and lactation and inadequate daily intake of certain nutrients.

This study found that combining microneedling with topical vitamin D3 improved hair regrowth and decreased alopecia severity more effectively than microneedling alone in patients with localized alopecia areata, with sustained efficacy across different ages, sexes, and disease durations, and only mild transient adverse effects.

This case study reports co-localized vitiligo and alopecia areata on the scalp of a 33-year-old Indian male, with marked improvement following intralesional corticosteroid treatment, suggesting a shared autoimmune pathogenesis.

The study reports that vitamin E improves hair-follicle growth and dermal papilla cell proliferation in vitro by modulating the lncRNA2919/STAT1/SHH axis in Angora rabbits, enhancing cellular antioxidant capacity.

In this cross-sectional study of Indonesian men, researchers observed a significant negative correlation between serum vitamin D levels and the severity of androgenetic alopecia, suggesting that lower vitamin D concentrations are associated with more severe hair loss, although causality was not established.

This narrative review proposes the concept of "repigmentation competence" for vitiligo lesions, suggesting that therapy responses are influenced by lesion-specific biological factors related to immune, regenerative, regulatory, and microenvironmental processes, and highlights the emerging role of combination therapies targeting these pathways.

This review examines human-relevant in vitro models for studying pigmentation disorders, identifying both challenges and advancements in replicating human pigmentation processes and disease-specific pathology in vitro.

This study suggests that a Lentinula edodes extract can improve skin barrier function, hydration, and sebum regulation, possibly by modulating vitamin D pathways, in individuals with oily and acne-prone skin.

This study found that intralesional Vitamin D3 injections were comparable in efficacy to intralesional triamcinolone for patchy alopecia areata, with a non-significant trend towards better outcomes and fewer local adverse effects.

This review suggests that female and male hair loss patterns differ due to hormonal influences, metabolic factors, and genetic loci, with female pattern hair loss potentially occurring without androgen influence, highlighting the need for distinct clinical management approaches.

This review highlights that a comprehensive approach combining pharmacological, immunomodulatory, and regenerative interventions, including phototherapy enhanced with topical treatments and JAK inhibitors, appears effective and promising in the management of vitiligo by addressing its autoimmune and melanocyte-loss aspects.

The researchers designed a Janus microneedle system for treating vitiligo, which targets the skin’s layers to regulate the immune response, promote melanocyte regeneration, and enhance pigment transfer, offering a new precise treatment approach for this condition.

This single patient case report observed that Vidarikandadi Kala Basti, an Ayurvedic Panchakarma procedure, was linked to modest improvements in Vitamin B12 levels and clinical symptoms, but larger studies are needed to determine its potential role in managing Vitamin B12 deficiency.

In this case report, a 22-year-old male with Vitamin B12 deficiency showed improved clinical symptoms and a modest rise in Vitamin B12 levels after undergoing classical Panchakarma therapy, though the authors emphasize that causality remains undetermined and further research is necessary.

This case report described the use of Vidarikandadi Kala Basti, a Panchakarma procedure, which was associated with improved symptoms and a modest Vitamin B12 increase in a patient with deficiency; however, the authors noted that causality cannot be established, and further controlled studies are needed.
