PubMed ID: 18661411. Abstract: IgA nephropathy is the most common glomerular disease in China, accounting for 38.8% of primary glomerular disease. It has been reported that 20.8% patients of IgA nephropathy had a different degree of crescent formation. From January 1995 to December 2004, 1000 patients had undergone cadaveric renal transplantation, and 1742 allograft renal biopsies were reviewed in the Department of Nephrology at Jinling Hospital, Nanjing University. Among them, 18 cases were found with crescent formation, in which 10 patients were diagnosed as recurrent or de novo IgA nephropathy because their immunofluorescence showed strong IgA deposition in mesangial area and capillary. The initial treatment protocol was CsA+Azp+Pred, except in two cases of CsA+MMF+Pred. There were 8 males and 2 females, with ages from 25 to 69 (mean of 37.1) years old. All of them showed progressive renal dysfunction with increasing level of serum creatinine ranged from 1.48 to 6.25 mg/dL. Seven cases presented edema with an increasing level of proteinuria (1.36 to 3.58 g/24hr), and nine cases presented with hematuria ranging from 50 to 1250 x 10(4)/mL (one showed gross hematuria). In pathological examinations, they showed mesangial proliferation and matrix expansion with 10% to 66.7% crescents (mean of 37.5%) in their allograft renal biopsy's samples. All patients changed their immunosuppressive regimens; however, nine of them eventually advanced to ESRD and returned to hemodialysis after 6 to 36 months. Two cases received second renal transplantation after six months to five years, and one kept stable renal function with 2.5 mg/dL of serum creatinine after three years of follow-up. IgA nephropathy with crescentic formation was not rare in renal allografts or native glomerulonephritis in Chinese patients. These patients showed rapidly progressive renal dysfunction, and most of them lost graft function and needed hemodialysis therapy.[Abstract] [Full Text] [Related] [New Search]
