[Significance of serum cholesterol and fibrinogen in evaluating the risk of glomerulosclerosis in children with nephrotic syndrome].

ABSTRACT

OBJECTIVE: To investigate the significance of serum cholesterol and fibrinogen (Fib) in evaluating the risk of glomerulosclerosis in children with nephrotic syndrome. METHODS: Sixty-three children with primary nephrotic syndrome were divided into two groups according to their pathological types minimal change glomerulopathy (MCG) (n=39) and focal segmental glomerulosclerosis (FSGS) groups (n=24). Serum levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), non-HDL-C and Fib and 24-hour urinary protein excretion were retrospectively analyzed. RESULTS: Serum levels of TC, non-HDL-C, and LDL-C were significantly higher in the FSGS group than in the MCG group (P<0.05), but there were no significant differences in HDL-C, Fib and 24-hour urinary protein excretion between the two groups (P>0.05). According to the results of logistic regression analysis, high levels of LDL-C, non-HDL-C and TC were risk factors for FSGS (P<0.05). In patients whose proteinuria did not disappear after taking enough glucocorticoid for 4 weeks, the level of non-HDL-C was significantly higher in the FSGS group than in the MCG group (P<0.05); there were no significant differences in TC, LDL-C, HDL-C, and Fib between the MCG and FSGS groups (P>0.05). CONCLUSIONS: Serum cholesterol, especially non-LDL-C, is of great significance in evaluating the risk of glomerulosclerosis in children with nephrotic syndrome. There is no sufficient evidence to support serum Fib as a marker for predicting glomerulosclerosis in these children.
