Abstract: Objective To investigate the relationship between red cell distribution width(RDW) and renal function damage in children with nephrotic syndrome(NS). Methods 168 NS patients were chosen as the observation group, divided into three groups by eGFR level, while also divided into two groups by onset duration of 4 months. 100 healthy children were included as the control group. The blood routine, biomedical function of liver and kidney were detected. Data were analyzed by SPSS 21.0. Results ① Compared to control group, NS patients have higher levels of RBC[(4.86±0.69) vs (4.32±0.48)] and RDW[(13.39±1.69) vs (12.99±1.04)], P<0.05; ② RDW is higher in the third phase of renal function than the second [(14.60±1.36) vs(12.84±0.79)], and also higher in the onset duration of less than 4 months group than the control group [(13.66±1.78) vs (12.99±1.04)], P<0.05; Mean corpuscular volume is lower in the onset duration group of less than 4 months than the control group, and higher in the onset duration group more than 4 months than the onset duration group of less than 4 months, P<0.05. Conclusion The RBC, RDW are higher in children NS patients than in the healthy children; RDW is higher in the third renal function than the second renal function.
