[Effect of recombinant human growth hormone therapy on metabolic parameters in patients with craniopharyngioma].

Objective: To investigate the effects of recombinant human growth hormone (rhGH) on metabolic parameters in patients with craniopharyngioma surgeries. Methods: Totallys 30 patients with craniopharyngioma were included in this retrospective study. They were divided into growth hormone (GH) group and control group according to whether they received rhGH therapy or not. The following parameters, including body mass index (BMI), weight, waist circumstance, transaminase, fasting blood glucose, lipid profile and high-sensitivity C-reactive protein (hsCRP) were compared after rhGH therapy for 4-6 months. Results: In GH group, patients were 18-46 (30.0±8.8) years old. The duration after craniopharyngioma surgery was (12.9±5.4) years. Before rhGH therapy, they had got sufficient thyroid and glucocorticoid hormone replacement. After rhGH therapy, the body weight decreased from (92.3±20.1) to (87.6 ±14.6) kg ( P =0.190), with a reduction of BMI from (30.1±5.9) to (28.2±3.7) kg/m(2) ( P =0.120). The waist circumference decreased from (104.4±9.4) cm to (98.8±10.6) cm ( P =0.002). Alanine aminotransferase (ALT) decreased from (52±34) to (28±19) U/L ( P =0.029), with a reduction of aspartate transaminase (AST) from (46±21) to (33±18) U/L ( P =0.035) and γ-glutamyl transpeptadase (GGT) from (59±42) to (29±15) U/L ( P =0.02). hsCRP decreased from (5.3±4.9) to (2.3±2.8) mg/L ( P =0.006) and triglyceride (TG) decreased from (1.8±0.7) to (1.5±0.6) mmol/L ( P =0.028). Fasting blood glucose, low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) and free fat acid (FFA) were not significantly changed(all P >0.05). In the control group, the above mentioned parameters did not changed significantly during 4-6 months of observational period(all P >0.05). Conclusion: rhGH therapy improves metabolic parameters in patients after craniopharyngioma surgery by decreasing body weight, waist circumstance and fat deposit in liver, as well as lowering TG and hsCRP levels.
