Lipoprotein abnormalities in patients with secondary renal amyloidosis.
The prevalance of hyperlipidemia in chronic renal failure (CRF) patients is higher than in general population. Secondary amyloidosis is a common cause of CRF in Turkey. In this study, 25 patients with CRF due to secondary renal amyloidosis (amyloid-CRF), 15 patients with CRF without amyloidosis-CRF and 17 healthy controls were studied for serum lipid parameters. The mean serum lipoprotein (a) [LP(a)] level in the patients with amyloid-CRF was significantly higher than in the controls (p < 0.01). The mean serum apolipoprotein B (Apo B), apolipoprotein E (Apo E) and triglyceride levels in the patients with amyloid-CRF were very significantly higher than in the controls (p < 0.001). The mean serum total cholesterol, low-density lipoprotein (LDL) levels in the patients with amyloid-CRF were higher than in the controls (p < 0.05). The mean serum apo AI levels in the patients with amyloid-CRF was very significantly lower than in the controls (p < 0.001). The mean serum high-density lipoprotein (HDL) in the patients with amyloid-CRF was lower than in the controls (p < 0.05). The mean serum Lp (a), Apo AI, Apo B and Apo E levels in the patients with amyloid-CRF were significantly higher than in the patients with CRF (p < 0.01). The mean serum total cholesterol, trigliserides, LDL and HDL levels in the patients with amyloid-CRF were higher than in the patients with CRF (p < 0.05). There was not any correlation with serum lipid parameters and serum albumin and urine protein levels (p > 0.05). Our study suggests that serum lipid parameters are abnormal and might be the risk factor of atherosclerotic vascular disease and contribute to renal disease progression in the patients with secondary renal amyloidosis and lipid abnormalities were different from CRF with various etiology, without amyloidosis.
