Early identification and prognostic stratification of delayed graft function following renal transplantation has significant potential to improve outcome. Mass spectrometry analysis of serum samples, before and on day 2 post transplant from five patients with delayed graft function and five with an uncomplicated transplant, identified aminoacylase-1 (ACY-1) as a potential outcome biomarker. Fol...

BACKGROUND Administration of HMG-CoA reductase inhibitors (statins), prior to ischemia or prior to reperfusion has been shown to decrease ischemia-reperfusion renal injury in animal studies. It is unknown whether this protective effect is applicable to renal transplantation in humans. The aim of this study was to determine the relationship between prior statin use in renal transplant recipients...

Now THAT THE RESULTS of kidney transplantation are improving to relatively high rates, we need more sensitive measures of transplant outcome than graft and patient survival. A subjective assessment by the transplant surgeon, evaluated as grade A, B, C. D, or Fat 3 months, 6 months, I year, and annually thereafter has long been available to the UCLA Transplant Registry but has been largely unuse...

Demineralized bone matrix has been successfully commercialized as an alternative bone graft material that not only can function as filler but also as an osteoinductive graft. Numerous studies have confirmed its beneficial use in clinical practice. Heterotopic ossification after internal fixation combined with the use of demineralized bone matrix has not been widely reported. In this paper we de...

Cyclosporine A (CsA) is a substrate for cytochrome P450 3A and the efflux transporter P-glycoprotein (P-gp; ABCB1), both abundantly expressed in the kidney. We retrospectively investigated the role of polymorphisms in CYP3A4, CYP3A5 and ABCB1 kidney graft donors on recipient renal function and subsequent graft loss, in a long-term cohort of recipients transplanted between 1990 and 2005. DNA fro...

Since the beginning of organ transplantation, graft preservation has been one of the most important concerns. Ischemia reperfusion injury (IRI), which plays an important role in the quality and function of the graft, is a major cause for increased length of hospitalization and decreased long term graft survival. Among numerous attempts which have been made to minimize graft damage associated wi...

BACKGROUND The purpose of this study was to examine the incidence of oxalate deposits in native and renal allograft biopsies, and its impact on graft function. METHODS The renal biopsy files at The Johns Hopkins University between 2000 and 2006 were searched to identify biopsies with oxalate deposits, determine the density of oxalate deposits in renal graft biopsies, compare graft histology a...
