OBJECTIVE: Growing evidence suggests the presence of a complex interplay between hypertension as well as type 2 diabetes mellitus (DM) and osteoporosis. The present study was designed to investigate a possible effect of type 2 DM on bone remodelling markers such as osteoprotegerin and N-terminal propeptide of type 1 collagen (P1NP) in hypertensive patients.
DESIGN AND METHODS: The 100 study participants were divided into three groups according to the presence of DM and hypertension: group one included diabetic hypertensive subjects, group 2 included hypertensive subjects without diabetes and group 3 included subjects without hypertension and without DM (controls). Blood sampling for metabolic parameters, including osteoprotegerin, P1NP, adiponectin, fasting glucose, HbA1c , CRP, homeostasis model assessment-insulin resistance, homeostasis model assessment-beta function was performed.
RESULTS: Circulating P1NP increased from group 1 to group 3 in a continuous fashion. P1NP was significantly lower in hypertensive subjects with DM (group 1), than in groups 2 and 3 (p < 0.0001). P1NP, was marginally lower in diabetic hypertensive subjects as compared with nondiabetic subjects with hypertension (p = 0.079). Circulating osteoprotegerin did not differ significantly between groups (p = 0.593).
CONCLUSIONS: In the present study, bone formation marker, P1NP, was significantly lower in diabetic hypertensive subjects as compared with nondiabetic subjects with and without hypertension. P1NP was inversely associated with parameters of glucose homeostasis such as fasting glucose, HbA1c and positively with homeostasis model assessment-beta cell function. Type 2 DM was associated with an adverse effect on bone formation independently of age, sex and exposure to anti-diabetic drugs.
