RESUMEN
AIM: To reveal factors accelerating development of chronic renal failure (CRF) in patients with insulin-dependent diabetes mellitus type I (DM-I). MATERIALS AND METHODS: A retrospective analysis of case histories was made for 40 patients with DM-I exhibiting progression of proteinuric stage of diabetic nephropathy prior to CRF stage. Clinical-laboratory indices were compared for patients with slow (group 1, n = 17) and fast (group 2, n = 23) development of CRF. RESULTS: Patients of group 2 had significantly higher levels of glycosylated hemoglobin, total cholesterol, triglycerides in the blood, urine protein excretion, systolic and diastolic blood pressure than patients of group 1. Also, patients of group 2 had not taken antihypertensive drugs regularly. CONCLUSION: Factors of risk of CRF early development of DM-I patients comprise unsatisfactory compensation of carbohydrate metabolism, hyperlipidemia, high proteinuria, arterial hypertension and inadequate antihypertensive therapy.
