title: Effect of protein-restricted diet on serum lipids and atherosclerosis risk factors in patients with chronic renal failure.
abstract: Early changes in lipid metabolism and appearance of atherosclerosis risk factors play a key role in the development of cardiovascular disease of chronic renal failure (CRF). In the effort to evaluate the effects of protein restricted diet on dyslipidemia, we studied 122 patients with CRF (S-creatinine 1.3-9 mg/dl); 58.2% of whom were on antihypertensive drugs treatment. Patients had been separated into 6 groups: group 1 was kept on a free diet; groups 2, 3, 4, 5, 6 were kept on a protein-restricted diet from 12, 24, 36, 48, 60 months, respectively. We found hypertriglyceridemia, pathologic levels of esterified cholesterol in high density lipoprotein (HDL-C) and pathologic apolipoprotein A1/B ratio in group 1; the comparison with other groups--whose values were normal range after 12, 24 months of treatment--showed significant differences. The lipidic parameters were independent of the duration of CRF and of patients' age. Serum creatinine showed a significant correlation with tryglicerides and HDL-C values only in group 1. Total cholesterol and apolipoprotein B were significantly greater in hypertensives than in normotensives. In our opinion, a moderate restriction in protein intake could be effective in preventing and in halting the early alterations of lipid metabolism in CRF.
