Abstract

Background:

The objective of the study was to describe the prevalence, clinical characteristics and aetiological diagnosis in children with disorders of sex development (DSDs) presenting to a tertiary referral centre.

Methods:

This is a retrospective review of all cases of DSD referred to the Paediatric Endocrine Unit in Inkosi Albert Luthuli Central Hospital (IALCH) from January 1995 to December 2014.

Results:

A total of 416 children (15.1%; CI: 13.8%–16.5%) were diagnosed with DSD. The aetiological diagnosis based on the current classification [Lawson Wilkins Paediatric Endocrine Society (LWPES) and European Society for Paediatric Endocrinology (ESPE)] was sex chromosome DSD in 9.5% (n=33), 46 XX DSD in 33% (n=114) and 46 XY DSD in 57.5% (n=199). The most common diagnoses in descending order were a disorder in androgen synthesis and action (not classified) in 53% (n=182), ovotesticular DSD in 22% (n=75) and congenital adrenal hyperplasia (CAH) in 10% (n=36). Overall the median age of presentation was 10 months (IQR: 1 month–4.5 years). There was a significant relationship (p<0.001) between the age of presentation and aetiological diagnosis. The majority (97%) of African patients had a diagnosis of 46 XX DSD. Prematurity was present in 47% (n=83) of children with 46 XY DSD (p<0.001).

Conclusions:

DSD is not an uncommon diagnosis in African patients in sub-Saharan Africa. The most common aetiological diagnosis is 46 XY DSD in androgen synthesis and action, followed by ovotesticular DSD. CAH is only the third most common disorder.

Keywords: 46 XX disorder of sex development; 46 XY disorder of sex development; congenital adrenal hyperplasia; disorder in androgen action or synthesis; disorder of sex development; ovotesticular disorder of sex development; sex chromosome disorder of sex development; Turner syndrome
