AIMS: To test the effect of oral hormone replacement therapy (HRT) on plasma C-reactive protein (CRP), soluble vascular cell adhesion molecule-1 (VCAM-1), soluble intercellular adhesion molecule-1 (ICAM-1) andIL-6 concentrations and leucocyte count in post-menopausal women with Type 2 diabetes. METHODS: Post-menopausal women with Type 2 diabetes (n = 61) were randomized in a double-blind fashion to receive either continuous combined hormone replacement therapy (n = 29) with conjugated equine oestrogen (0.625 mg/day) plus medroxyprogesterone acetate (2.5 mg/day) or placebo (n = 32) for 6 months. Study variables were measured at baseline and at the end of the study. RESULTS: Eight women randomized to hormone replacement therapy and four women assigned to placebo group dropped out of the study. Plasma CRP increased (2.2 mg/l, 95% confidence interval 0.3-4.1 mg/l) significantly (P = 0.02) in women treated with HRT (n = 21) compared with placebo (n = 29) taking baseline CRP, body mass index (BMI) and smoking status into account. Plasma levels of cell adhesion molecules, IL-6 and leucocyte count did not change significantly during the study. CONCLUSIONS: These findings indicate that oral HRT with conjugated equine oestrogen plus medroxyprogesterone acetate increases plasma CRP levels but not necessarily global inflammatory activity in post-menopausal diabetic women. An increase in plasma CRP may potentially increase risk of a cardiovascular event.
