Plasma homocysteine and Cystatin C levels of 360 chronic haemodialysed patients were measured in fasting (191 men, mean age: 55.5 years; and 169 women, mean: 62.9 years). The patients were divided into subgroups: diabetes mellitus (34 men and 38 women 7 vs 8 IDDM). obliterative arteriosclerosis (68 men and 61 women), cardiovascular complications (75 men and 84 women) and stroke (16 men and 12 women), and after renal transplantation in chronic rejection (15 men and 5 female). Homocysteine was determined by IMx analyser from Abbott by FPIA method. Immunoturbidimetric method was used for quantification of Cystatin C (PETIA). The lowest Cystatin C concentration was found in diabetic patients (4.35±0.15 mg/l in men and 3.18±1.77 mg/l in women) and the highest one occurred in anuric and bilateral nephrectomised and transplanted chronic rejected patients (6.075 mg/l in men and 6.35 mg/l in women: p<0.001). The homocysteine levels (24.98±2.94mmol/l in men and 23.88±1.76mmol/l in women) exceeded the upper limit of reference range (<15.0mmol/l). There was a significant difference in favour of subgroup of cardiovascular (27.25mmol/l in men and 26.87mmol/1 in women) and stroke patients (27.16mmol/l in men and 30.76mmol/l in women p<0.001). Elevated levels were found in chronic rejected patients with accelerated arteriosclerotic events (25.94mmol/l in men and 27.43mmol/l in women). Good positive linear correlation was found between serum homocysteine and Cystatin C levels (r=0.2393 and 0.2252). The authors demonstrated hyperhomocysteinaemia associated with high Cystatin C concentration in four subgroups of haemodialysed patients (obliterative and accelerated arteriosclerosis. cardiovascular disease, and cerebrovascular complications and stroke). |
