Aims:Data regarding the presentation and course of patients with congenital adrenal hyperplasia (CAH) is scarce in South Asia. We aimed to fill that gap by collating our experience with CAH and comparing it with findings from few other centres around the world for pertinent differences.Methods:We retrospectively analysed the records of 86 CAH patients seen at our tertiary care centre in Eastern-India from 1996 to 2010.Results:Forty-five patients (52.3%) had classic disease and 41 (47.7%) had non-classic disease (NC CAH). In the classic CAH group, 18 (20.9%) had salt wasting CAH (SW CAH) while 27 (31.4%) had simple virilising disease (SV CAH). Ten (11.6%) had a 46,XY karyotype. Patients with SW CAH were diagnosed earlier in infancy at a median age of 0.5 year, than those with SV type, who were diagnosed at 9 years (P < 0.05). The NC CAH patients were diagnosed still later, at 20.4 years. In patients with SW CAH, boys were diagnosed at an earlier median age of 0.1 year than girls who were diagnosed at 6.4 years (P < 0.05). Sixteen girls (21% of the girls) underwent vaginoplasty of whom four required additional clitoroplasty. One girl needed bilateral laparoscopic adrenalectomy. One NC CAH patient had a successful assisted pregnancy. Hypothyroidism, found in seven (8.1%) was the commonest coexisting abnormality.Conclusion:The skewed male: female ratio suggested that a substantial proportion of males were being missed and consequently may die. Majority of the diagnosed patients (n= 55, 64%) have been lost to follow-up. Remaining patients could be reasonably controlled with standard therapy.
