Background: 25–50% of paediatric patients with chronic endocrine diseases are lost for follow-up in adult care.

Aims and objectives: A standardised medical and psychological work-up to identify disease specific morbidity and to comprehend quality of life in adolescents with chronic endocrine diseases at the time of transition from paediatric to adult care.

Methods: The quality of life (DISABKIDS1 and KIDSCREEN2) and serum markers of fertility (anti-mullerian hormone (AMH), Inhibin B, oestradiol, testosterone) were examined in adolescence after near final height was reached. Results are presented as mean±S.D. Patients and parents gave informed consent and approval by the local ethics committee was obtained.

Results: 120 patients aged 14–30.6 years (70 females, 50 males) were recruited: Turner Syndrome (TS) (n=23), congenital adrenal hyperplasia (n=21), hypopituitarism with hypogonadotrophic hypogonadism (HH) and T/E2 replacement (HHH; n=9), hypopituitarism without HH (HP; n=34), SGA short stature (n=18) and others (n=15). DISABKIDS TRS was 82.3±14.0 (reference 76.9±18.31; n.s.). KIDSCREEN TRS (ten sub-scales) ranged between 64.7±24.9 and 92.9±11.6 (reference 66.8±19.3 and 90.3±15.52; n.s.).

Conclusion: The quality of life in these patients is normal. HH in girls is associated with lower serum AMH and Inhibin B as in TS. HH in boys is related to higher serum AMH and lower Inhibin B. This may reflect gonadal immaturity in females and males with HH but the relevance for gonadal reserve remains unclear.
