TESTOSTERONE CHANGES IN PATIENTS WITH LIVER CIRRHOSIS BEFORE AND AFTER ORTHOTOPIC LIVER TRANSPLANTATION AND ITS CORRELATION WITH MELD

Abstract

CONTEXT: Hypogonadism is a common clinical situation in male patients with liver cirrhosis. OBJECTIVES: The aim of the present study was to evaluate the effects of orthotopic liver transplantation on testosterone, free testosterone and sex hormone-binding globulin in male with advanced liver disease and also to determine the relationship of these changes with Model for End-stage Liver Disease (MELD) score. METHODS: In a prospective study, serum levels of testosterone, free testosterone and sex hormone-binding globulin of 30 male adult patients with end-stage liver disease were measured 2 to 4 hours before and 6 months after orthotopic liver transplantation. RESULTS: Total testosterone levels increased after orthotopic liver transplantation and the number of patients with normal testosterone levels increased from 18 to 24. Free testosterone mean level in the pre-transplant group was 7.8 pg/mL and increased to 11.5 pg/mL (P = 0.10) and sex hormone-binding globulin level decreased after orthotopic liver transplantation returning to normal levels in MELD ≤ 18 - group (A) (P<0.05). CONCLUSIONS: Serum level changes of testosterone, free testosterone and sex hormone-binding globulin are more pronounced in cirrhotic males with MELD ≤ 18. Serum levels of testosterone and free testosterone increase and serum levels of sex hormone-binding globulin decrease after orthotopic liver transplantation.
