Do serum prolactin levels correlate with antibodies against desmoglein in pemphigus vulgaris?

Pemphigus vulgaris is a chronic inflammatory disease of skin, the etiology of which is not completely known. Despite the latter, anti-desmoglein antibodies play a proven role in the pathogenesis. Recent studies showed an etiologic effect for prolactin in the pemphigus vulgaris. This study aimed to quantify the correlation between serum prolactin levels and anti-desmoglein antibodies in patients with pemphigus vulgaris. Prolactin and antibodies against desmoglein 1 and 3 measured with ELISA in 14 new subjects of pemphigus vulgaris. There was no statistically significant relation between both serum prolactin and anti-desmoglein1 levels (r = 0.02, = 0.47) and serum prolactin and anti-desmoglein 3 levels (r= -0.09, = 0.38). This study indicates that no correlation was found between serum prolactin levels and anti-desmoglein 1 levels and serum prolactin and anti-desmoglein 3 levels. However, other studies should be initiated regarding exact molecular and cellular effects of prolactin in the pathogenesis of pemphigus vulgaris.
