ABSTRACT
Chronic renal failure is becoming an increasingly common disease. Diabetes mellitus is a frequent cause of end stage renal disease. Parathyroid disorders are seen commonly in patients with end stage renal disease. [E.S.R.D]. We compared 42 diabetic patients with 36 non-diabetic patients. All of them had ESRD on regular hemodialysis. Diabetic patients were subdivided into two groups: Insulin dependent and non insulin dependent diabetic. In all patients we measured the main biochemical parameters together with plasma calcium, phosphorus, magnesium, intact parathyroid hormone [I.PTH] and insulin level in blood. Diabetic patients showed lower levels of I-PTH than non-diabetic patients on regular haemodialysis [HD]. Also, insulin dependent diabetic patients showed lower but not significant levels of l-PTH than non insulin dependent diabetic patients
