Status of Serum Vitamin D Level Among Patients With Alopecia Areata in a Tertiary Care Hospital, Bangladesh

This study aimed to assess the serum Vitamin-D levels in patients with alopecia areata compared to healthy individuals. Conducted at Anwer Khan Modern Medical College in Bangladesh from January 2018 to December 2019, it included 30 patients with alopecia areata (Group A) and 30 healthy controls (Group B). The mean serum Vitamin-D level in the alopecia areata group was significantly lower at 8.63 ± 2.24 ng/mL compared to 30.26 ± 7.81 ng/mL in the control group (P<0.0001). This significant deficiency was observed across all severity levels of alopecia areata, as measured by the SALT score, with P values less than 0.0001 when compared to controls. The study concluded that a deficiency in vitamin D is a potential contributing factor to alopecia areata, with lower levels correlating with increased duration and severity of the disease, suggesting that vitamin D supplementation could play a role in treatment.
