A Study of Serum Prolactin in Dermatological Diseases in a Tertiary Care Hospital of Assam

The study conducted on 200 subjects, including 150 patients with psoriasis, alopecia areata, and vitiligo, and 50 healthy controls, found that serum prolactin levels were significantly higher in patients with these dermatological diseases compared to the control group. The mean serum prolactin levels were 19.2 ng/ml for psoriasis, 20.6 ng/ml for alopecia areata, and 16.4 ng/ml for vitiligo. Additionally, there was a significant correlation between serum prolactin levels and disease severity in patients with psoriasis and alopecia areata. These findings suggest that prolactin may contribute to the pathogenesis of these conditions and could serve as a biochemical marker for disease severity in psoriasis and alopecia areata.
