To assess the multiple risk factors reported to be associated with onset of serious bacterial, fungal, viral, and protozoal infections in renal allograft recipients, a retrospective study of all renal transplantations performed at Yale-New Haven Medical Center from the inception of the transplantation program in December, 1967, to December, 1975, was undertaken. Ninety-six renal allograft trans...

Acute transplant glomerulopathy transplant glomerulopathy (TG) is a common cause of late renal allograft loss. We describe a unique case of a renal transplant recipient who developed rapid-onset nephrotic-range proteinuria and acute kidney injury secondary to C4d negative acute TG. Two courses of intravenous Rituximab resulted in significant improvement in proteinuria and allograft function. In...

abstract  background: despite the long-standing association of macrophage migration inhibitory  factor (mif) with delayed-type hypersensitivity response, the potential role  of mif in chronic allograft nephropathy is unknown. the association between upregulation of mif expression, macrophage and t cell infiltration and the severity of  chronic allograft nephropathy suggests that mif may be an i...

BACKGROUND In vitro studies have demonstrated that inflammatory mediators such as the cytokines TNF alpha and IL-1 upregulate or induce de novo expression of cell adhesion molecules on endothelial and epithelial cells. In the present study the expression of the cell adhesion molecules ICAM-1, VCAM-1, E-selectin and PECAM-1 was investigated in renal biopsies from patients with primary renal dise...

Intratubular calcification is a common finding in renal allografts. However, possible harmful effect of this calcification is not well recognized, and allograft failure purely due to this condition has not been reported. We report a kidney transplant recipient who suffered from severe secondary hyperparathyroidism and unexplained early allograft failure. A diagnosis of acute phosphate nephropat...

OBJECTIVES Despite increased use of diabetogenic immunosuppressive drugs and increased incidence of new-onset diabetes after transplant in renal allograft recipients, there are few case studies on the subject of de novo allograft diabetic nephropathy and interstitial fibrosis/tubular atrophy without specific glomerular changes. We sought to study the outcomes of allograft diabetic nephropathy a...

Viral infections are an important complication of solid organ transplantation. Although polyoma is the virus that most commonly infects the renal allograft, adenoviral infections are also reported. We describe the clinical and pathologic findings in a patient with adenoviral infection associated with acute rejection of the renal allograft. The pathologic findings of adenovirus infection usually...

Sarcoidosis is a multisystem disorder of unknown aetiology characterized by the accumulation of lymphocytes, mononuclear phagocytes, and non-caseating granulomas in involved tissues. Renal involvement leading to renal function deterioration in sarcoidosis is rare: it is observed in <10% of patients. In the relevant literature, there have been only a few cases of sarcoidosis recurrence in renal ...

OBJECTIVES Renal transplantation is the preferred method for most patients with end-stage renal disease, however, acute renal allograft rejection is still a major risk factor for recipients leading to renal injury. To improve the early diagnosis and treatment of acute rejection, study on the molecular mechanism of it is urgent. METHODS MicroRNA (miRNA) expression profile and mRNA expression p...

The effect of recipient hepatitis C virus (HCV) infection on renal allograft loss and acute rejection in kidney transplantation remains controversial. We studied 354 renal allograft recipients transplanted during 1996 to 2001 who had HCV antibodies (Ab) measured before transplantation. The primary outcome was death-censored allograft loss and the secondary outcome was acute humoral rejection (A...
