Abstract in Portuguese
Objetivo: Avaliar a influência da terapia com tibolona no metabolismo dos carboidratos e lipídeos de pacientes na pós-menopausa portadoras de diabetes mellitus tipo 2. Método: estudo prospectivo, longitudinal, aberto e controlado envolvendo 24 mulheres na pós-menopausa portadoras de diabetes mellitus tipo 2, com média de idade de 57,5 ± 4,8 anos, tratadas seqüencialmente com placebo (6 meses) e tibolona-2,5 mg/dia (6 meses). Parâmetros clínicos, antropométricos, bioquímicos, hormonais e ultra-sonográficos foram avaliados no período basal, após 6 (tempo 1) e 12 meses de acompanhamento (tempo 2). Análise estatística foi realizada utilizando-se ANOVA para medidas repetidas, com nível de significância 5%. Resultados: com os 6 meses de uso da tibolona, evidenciamos reduções significativas nos sintomas climatéricos avaliados através do índice de Blatt-Kuperman, assim como no percentual de gordura corporal, circunferência abdominal, pressão arterial diastólica, e níveis séricos de transaminases, triglicerídeos e HDL-colesterol. Não houve variações significativas nos níveis de glicose e insulina de jejum, hemoglobinaglicada, área sobre a curva da glicose, área sobre a curva da insulina, índice QUICKI, colesterol total e LDL-colesterol. A avaliação ultra-sonográfica não revelou variações significativas do volume uterino e espessura endometrial. Efeitos colaterais surgiram apenas durante o primeiro mês de uso da tibolona (cefaléia e mastalgia em 8,3% e sangramento genital em 16,6%). Conclusão: o tratamento com tibolona em curto prazo mostrou-se uma alternativa viável para pacientes na pós-menopausa portadoras de diabetes mellitustipo 2.

Abstract in English
Objective: to determine the effects of tibolone on the glycemic and lipid metabolism in postmenopausal women with Type 2 diabetes mellitus. Method: a prospective, longitudinal, open and controlledstudy involving 24 postmenopausal women with Type 2 diabetes mellitussequentially treated with placebo (6 months) and 2.5 mg/day tibolone (6 months). Clinical evaluation, anthropometric parameters, biochemical and hormonal measurements, and transvaginal ultrasonography were performed at baseline and after 6 (time 1) and 12 months of follow-up (time 2). Statistical analysis was performed by repeatedmeasures analysis of variance, with the level of significance set at 5 %. Results: After 6 months the tibolone use, we observed significant reductions in the climacteric symptoms evaluated by the Blatt-Kupperman index, % body fat, abdominal circumference, diastolic arterial pressure, and in the serum levels of aminotransferases, triglycerides and HDL-cholesterol. There were no significant variations in fasting glucose and insulin levels, glycosylated hemoglobin, glucose-area under the curve (AUC), insulin-AUC, quantitative insulin sensitivity check index (QUICKI), total cholesterol and LDL-cholesterol levels. Ultrasonographic evaluation showed no significant changes in uterine volume or endometrial thickness. Side effects were present only during first months of tibolone use (headache and mastalgia in 8.3% and genital bleeding in 16.6%). Conclusion: The short-term treatment with tibolone showed to be a good alternative for postmenopausal women with Type 2 diabetes mellitus.
