Carbohydrate-lipid profile and use of metformin with micronized fenofibrate in reducing metabolic consequences of craniopharyngioma treatment in children: single institution experience

J Pediatr Endocrinol Metab. 2015 Jan;28(1-2):45-51. doi: 10.1515/jpem-2014-0425.

Abstract

Aim: To evaluate auxology and metabolic disturbances in children with craniopharyngioma, and to present observational results of treatment of metabolic sequels with metformin and micronized fenofibrate.

Methods: The studied group comprised 22 children [median age at diagnosis 10.5 (0.17-16.75) years; median follow-up 5.1 years]. Assessment included height standard deviations (SDS), body mass index (BMI) SDS, concentrations of lipids, glucose and insulin (fasting or oral glucose tolerance test) and homeostatic model assessment of insulin resistance (HOMA-IR) index. Ten adolescents with hyperinsulinemia and dyslipidemia received therapy with metformin (500-1500 mg/daily) and micronized fenofibrate (160 mg/daily).

Results: At diagnosis, median hSDS was -1.66 (range: -4.08; +0.1). Nine (40.9%) children were growth hormone-treated. There was gradual increase of BMI SDS, 18 (81.8%) patients being overweight at the final assessment. Dyslipidaemia was found in 19 patients (86.4%), hyperinsulinaemia in 11 patients (50%) and elevated HOMA-IR in 15 patients (68.2%). Decrease of triglycerides [median 263.5 (171-362) mg/dL vs. 154 (102-183) mg/dL] and HOMA-IR [8.64 (5.08-12.65) vs. 4.68 (0.7-7.9)] was significant in the group treated with metformin and fenofibrate for 6 months.

Conclusions: Significant auxologic changes and metabolic abnormalities were found in children treated for craniopharyngioma. The use of metformin and fenofibrate seemed to attenuate these disturbances in a short-term observation.
