Abstract:
Objective To investigate the relationship among urinary protein molecular weight of IgA nephropathy ,renal tubu‐lointerstitium damage and clinical index ,and discuss the role of low molecular weight urinary protein in the mechanism of IgA pro‐gression .Methods A total of 34 patients with biopsy proven IgAN were studied .We detect the molecular weight of urinary protein by SDS‐PAGE .Data were processed with the classes of tubulointerstitial lesions and laboratory tests such as 24h urinary protein quantitation and serum creatinine(Scr) .Results The urinary protein were divided into four types according the SDS‐PAGE:the ball urinary protein group ,physiologic urinary protein group ,23 × 103 proteinuria group and 10 × 103 proteinuria group .Scores of tubu‐lointerstitial lesions ,twenty four hour urine protein quantitation and Scr level were all significantly higher in 10 × 103 proteinuria group than 23 × 103 proteinuria group (P<0 .05) .Conclusion 10 × 103 proteinuria may have close relationship with the progression of IgAN ,and it may be a useful index for the degree of tubulointerstitial lesions of IgAN .
