ABSTRACT

BK virus infection accompanied with plasma cell-rich infiltrates is a dilemma in renal transplant recipients. One young female patient diagnosed as BK virus-associated nephropathy with plasma cell-rich infiltrates at 16 months after renal transplant was treated with bortezomib and a sequential immuno-suppressive protocol of tacrolimus combined with leflunomide. After a short period of reduction, her serum creatinine increased slowly with stable BK viruria. The patient underwent repeat biopsy. The histologic changes showed a decrease in plasma cells and CD20+ cells in the allograft, but the other mononuclear cells showed no difference from the first biopsy. The immunosuppressive protocol was converted to tacrolimus combined with enteric-coated mycophenolate sodium. Her serum creatinine decreased gradually during 6 months of follow-up. We speculate that bortezomib can be used in BK virus-associated nephropathy accompanied with plasma cell-rich infiltrates, and this effect might be mediated through a decrease of plasma cells and CD20+ cells in the allograft. The dosage and time of therapy need to be explored in the future; additional studies of large samples are needed.

ABSTRACT

Proliferative glomerulonephritis with monoclonal IgG deposits manifesting as a nephrotic syndrome recently has been described as a renal disease with the pathological features of mesangial and subendothelial deposits of monoclonal IgG. Eight cases of recurrent proliferative glomerulonephritis with monoclonal IgG deposits after a renal transplant have been reported. Almost all of these patients had a certain remission of proteinuria by steroids alone or with cyclophosphamide, and had further remission through other special treatments (ie, rituximab and plasmapheresis). We present a case of recurrent proliferative glomerulonephritis with monoclonal IgG deposits of the IgG3? subtype after a renal transplant, which was insensitive to pulse intravenous methyl-prednisolone and cyclophosphamide remitted by double filtration plasmapheresis. This case report reveals that recurrent proliferative glomerulo-nephritis with monoclonal IgG deposits may be insensitive to intravenous pulse therapy of methylprednisolone and cyclophosphamide. We advocate double filtration plasmapheresis as an effective treatment of proliferative glomerulo-nephritis with monoclonal IgG deposits on remission of proteinuria.

ABSTRACT

OBJECTIVE: To investigate the correlation between circulating endothelial cells (CECs) and vascular lesions in renal allografts. METHODOLOGY: Sixty-two renal transplant patients were divided into four groups according to biopsy data. CECs were isolated from peripheral blood with anti-CD136-coated immunomagnetic Dynabeads and counted by microscopy during biopsy. CEC numbers were compared in each group, as well as the correlation between CECs and C4d and vascular changes in different groups. RESULT: CECs counts were higher in the acute rejection (AR) with endarteritis group than in the normal group (p < 0.01), acute tubular necrosis (ATN) group (p < 0.01) and chronic allograft nephropathy (CAN) group (p < 0.01), there were no difference among ATN, normal and CAN) group (p = 0.587). There was no difference among the normal group without hyaline, normal group with hyaline and CAN with hyaline group. An increasing CECs count was related to C4d-positive AR (p = 0.008; κ score = 0.519) and infiltration of inflammatory cells (p = 0.002, κ score = 0.573) in proximal tubule cells (PTCs). The CECs count decreased after intensive therapy in five patients (p = 0.001). CONCLUSION: Elevation of the CEC count in blood was related to endarteritis. Elevation of CEC count was related to C4d deposition and infiltration of inflammatory cells in PTCs.

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.
