[Bone complications in diabetic subjects with good metabolic control and without any long-term complications--certain problems. Part III: The influence of hypertension and type 2 diabetes mellitus co-incidence of calcium, phosphorus and magnesium metabolism].

: Both high morbidity and potentiation of systemic complications emphasise significance of diabetes mellitus and hypertension co-incidence. The aim of the study was to analyse the influence of hypertension accompanied with type 2 diabetes mellitus on calcium phosphorus and magnesium metabolism. The study was performed in standard low-calcium diet conditions on the group of 49 patients with type 2 diabetes mellitus (among them 27 had hypertension), 14 patients with essential hypertension and 20 healthy persons. Both serum and urine concentration of creatinine, calcium, phosphorus, hydroxyproline, hydroxylysine and uric acid were analysed. Oral calcium load test was done. Serum alkaline phosphatase activity and oxalic acid urine excretion were also estimated. There were no significant differences between diabetic patients with and without hypertension as far as calcium, phosphorus or magnesium metabolism were concerned.
