Abstract

Objective: To evaluate the effects of long-term administration of GnRH agonist (GnRH-a) plus tibolone for uterine leiomyomatosis. Design: Prospective open clinical trial. Setting: Department of Gynecology, Obstetrics and Pathophysiology of Human Reproduction, University of Naples 'Federico II', Naples, Italy. Patient(s): Twenty-five subjects with symptomatic uterine leiomyomas. Intervention(s): Treatment for 2 years with leuprolide acetate (3.75 mg IM every 28 days) and tibolone (2.5 mg/d per os). Main Outcome Measure(s): Uterine and uterine leiomyoma sizes, endometrial thickness, lumbar spine bone mineral density (BMD), bone metabolism, lipid profile, myoma-related symptoms at baseline and every 6 months. Hot flashes and vaginal bleeding episodes recorded in a daily symptom diary. Result(s): After 6 months of treatment, a significant reduction was observed in uterine and leiomyoma volumes and myoma-related symptoms compared with baseline values. No significant change was observed in bone turnover, lumbar BMD, or serum total cholesterol, low-density lipoprotein cholesterol, or triglyceride levels. High-density lipoprotein cholesterol values were significantly lower than baseline values after 6 months of treatment but not after 18 months of therapy. A low mean number of hot flashes per day was observed. Conclusion(s): Long-term administration of GnRH-a plus tibolone reduces hot flashes and prevents bone loss without changing the lipid profile.
