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

This study examined serum prolactin levels in 150 patients with psoriasis, alopecia areata, and vitiligo, compared to 50 healthy controls, at a tertiary care hospital in Assam. Results indicated significantly higher prolactin levels in patients, with mean levels of 19.2 ng/ml for psoriasis, 20.6 ng/ml for alopecia areata, and 16.4 ng/ml for vitiligo, compared to 11.1 ng/ml in controls. In alopecia areata, prolactin levels correlated with disease severity, with mean levels of 11.22 ng/ml in mild, 21.66 ng/ml in moderate, and 27.49 ng/ml in severe cases. These findings suggest prolactin's potential role in disease pathogenesis and as a marker for severity, though larger studies are needed to confirm these results.
