Introduction: Quality of life (QoL) is a multidimensional indicator including several functions and represents an important evaluator of patient’s health, especially in chronic diseases. Treatment with aGnRH in Central Precocious Puberty (CPP) is source of stress for patients and families. The aim of our study is to evaluate QoL and levels of therapy-related stress in patients with CPP and in their families during and after treatment.

Material and methods: 56 patients (two males) with CPP attending a tertiary Endocrinological Outpatient Clinic in 2015 and 2016 were enrolled. The population was divided, according to their age, in 4 categories: G1: 3 patients, 4–7 years; G2: 15 patients, 8–12 years, G3: 13 patients, 13–18 years, G4: 25 patients beyond 18 years. Groups G1 and G2 were on therapy with aGnRH, G3 were off therapy, still on clinical follow up, G4 were off therapy. We also evaluated 30 controls paired for age and level of instruction. Each patient underwent 2 questionnaires: the ‘Pediatric Quality of Life Inventory’ (PedsQL) and a tailored ‘ad-hoc’ questionnaire to investigate self perception in CPP. Parents also underwent the latter questionnaire.

Results and discussion: No significant differences were detected comparing PedsQL scores among G1, G2 and G3 groups each others nor comparing patients and controls. A difference statistically significant was detected in the evaluation of physical functions between G2 and controls (P: 0.02). In G2 and G3 no significant association was found between the duration of treatment and the 4 functions of PedsQL. For the self perception questionnaire scores, although no significant differences among G1, G2 and G3 themselves nor between patients and their parents were detected, the scores trend showed in patients an amount of stress therapy-related increasing proportionally with age. For G4 a direct correlation was identified between duration of treatment and emotional stress, and lower scores about self-esteem were identified, referring both to the period of therapy and the period of questionnaire’s compilation.

Conclusion: In CPP, from the PedsQL, it appears that therapy with aGnRH only affects QoL on physical functions. Levels of emotional stress therapy-related, detected through ad-hoc questionnaire, increase in treated patients, independently from the treatment interruption. In off-therapy patients a decreased self-esteem and an indirect correlation between emotional stress and duration of treatment were found, underlining the effect of therapy in self perception.
