HUMAN-LEUKOCYTE ANTIGEN TYPING AND ASSOCIATED ABNORMALITIES IN PREMATURE OVARIAN FAILURE

A case-controlled study was designed to assess the distribution of human leukocyte antigens (HLA) A, B, Cw, DR and DQ, and associated abnormalities in patients with premature ovarian failure (POF). A total of 37 patients in a tertiary care centre were diagnosed as having POF; all were <37 years old. A subset was HLA-typed. The occurrence of associated diseases in patients with POF was recorded. A comparison of HLA typing was made between patients with POF and 100 organ donors from the same population. No statistically significant difference in the distribution of A, B, Cw, DR and DQ antigens was found between the study and control groups when corrected for the number of antigens tested. The commonest associated abnormality was positive autoimmune screen (43.3%). Abnormal thyroid function tests were detected in 23.3% of the patients. The observed high frequency of associated autoimmune phenomena in patients with POF points to an underlying autoimmune disorder in POF and warrants further studies to unravel the pathology of this condition.
