title: [Metformin efficiency for the adolescent PCOS treatment].
abstract: PCOS is a polyglandular heterogenic metabolic condition, which frequency in adolescence is defined between 11-26%. There are some aspects of PCOS which can be seen in a regular puberty and vice versa. This makes the adolescent PCOS a condition which is rather complicated to diagnose as well as to treat. The pathophysiology of PCOS is not fully clarified, but is well established the fundamental role of the insulin resistance and the hyperinsulinemia. This fact explains the detailed investigations of the insulin sensitizers use for the PCOS treatment. Nevertheless there is insufficient experience with this medication group for the adolescent PCOS treatment in Bulgaria.
  
  
  OBJECTIVE
  To evaluate the Metformin efficiency for the adolescent PCOS treatment.
  
  
  METHODS
  This is a prospective study including 55 girls with menstrual irregularities aged between 13 and 18 years. None of the subjects had previously been diagnosed with any endocrine pathology or had received any hormonal treatment for at least three months prior to their evaluation. They have been evaluated according to the diagnostic criteria for PCOS in adolescence accepted in 2010.
  
  
  RESULTS
  The incidence of PCOS in our research was 38.9%. In 66.7% of them the body mass index was higher than normal. Insulin resistance was diagnosed in 90.5%. The insulin resistance was improved in 80% of the PCOS patients after six months therapy with Metformin 2 x 850 mg/p.d. The menstrual function was regulated in 77.8% of the cases.
