title: Comparison of corticoid substitution versus combined oral contraception administration in the treatment of non-classic adrenal hyperplasia: a prospective study.
abstract: OBJECTIVE
  The clinical symptoms of non-classic adrenal hyperplasia (NCAH) are the same as those in patients with polycystic ovary syndrome (PCOS). The aim of our study was to compare conventional corticoid treatment of NCAH with the effect of combined oral contraception (COC) administration (used in treatment of PCOS) on clinical and laboratory parameters of NCAH.
  
  
  METHODS
  A prospective clinical study, cross-over design.
  
  
  METHODS
  Since 1999 from 298 hyperandrogenic women, eight patients having 21-hydroxylase deficient NCAH have been identified. They were divided equally into two groups according to the order of application treatment modality (hydrocortison vs. COC). Effect of treatment of both modalities on clinical symptoms (hirsutism - FG score, acne, menstrual cycle) and laboratory parameters (testosterone, androstenedione, dehydroepiandrosterone, dehydroepiandrosterone sulphate, sex hormone binding globulin (SHBG)) were evaluated.
  
  
  RESULTS
  We observed the decrease of plasma androgens in both groups, which did not differ significantly. Significant increase of SHBG (i.e. decrease of free androgens) was, however, documented in each period with COC administration. Not surprisingly, improvement of the most frequent clinical symptom of NCAH in our study group, oligomenorrhea, was also more apparent in COC. Hirsutism was only a minor problem in our group that did not allow to evaluate treatment effect of both the modalities
  
  
  CONCLUSIONS
  Our results indicate that ovarian suppression by COC administration can effectively suppress androgen production and improve the most frequent clinical symptom (irregular cycle) in patients with NCAH, so can be successfully used for the treatment at least under basal conditions. Whether corticosteroid substitution can be limited to patients with inadequate response to COC on plasma androgen levels or with signs of adrenal insufficiency requires further data.
