Multicenter StudyDuffy antigen receptor and genetic susceptibility of African Americans to acute rejection and delayed function.
The unique distribution of the alleles for the Duffy antigen receptor complex (DARC) that binds to chemokines may be associated with the rates of acute rejection and delayed allograft function (DGF) among African Americans. ⋯ The susceptibility of African American recipients to acute rejection and to DGF was not confirmed to be associated with DARC alleles or genotype. Future studies should exclude a potential role of donor-related DARC in transplant outcomes.

Clinical Trial Controlled Clinical TrialEarly detection of acute renal failure by serum cystatin C.
Acute renal failure (ARF) is associated with high mortality. Presently, no specific therapy for ARF exists. Therefore, early detection of ARF is critical to prevent its progression. However, serum creatinine, the standard marker to detect ARF, demonstrates major limitations. We prospectively evaluated whether serum cystatin C detected ARF earlier than serum creatinine. ⋯ Serum cystatin C is a useful detection marker of ARF, and may detect ARF one to two days earlier than creatinine.

Case ReportsTwo novel ADAMTS13 gene mutations in thrombotic thrombocytopenic purpura/hemolytic-uremic syndrome (TTP/HUS).
Thrombotic thrombocytopenic purpura (TTP) and hemolytic-uremic syndrome (HUS) are now considered to be variants of one single syndrome called thrombotic thrombocytopenic purpura/hemolytic-uremic syndrome (TTP/HUS). Key features are thrombocytopenia, hemolytic anemia, and subsequently impaired function of different organs, especially the kidneys and the central nervous system (CNS). One possible reason is the deficiency of von Willebrand factor-cleaving protease (vWF-CP) resulting in persistence of uncleaved, ultralarge von Willebrand factor multimers (ULvWFM). ⋯ Enteropathogenic E. coli- and Shiga-like toxin-negative patients who present with hemolytic or thrombocytopenic episodes and HUS like symptoms should be tested for vWF-CP deficiency and other noninfectious reasons for TTP/HUS since plasma substitution possibly provides an efficient therapeutic option for this subgroup of patients.

Epidemiologic data of renal diseases from a single unit in China: analysis based on 13,519 renal biopsies.
Renal biopsy specimens of 13,519 cases were collected during the period of January 1979 to December 2002 from the Research Institute of Nephrology, Nanjing University School of Medicine, Nanjing, China. Analysis of the data of this group of patients showed that primary glomerulonephritis (GN) remained the most important and prevalent renal disease in China. The ratio of primary to secondary GN was 2.75:1. ⋯ Membranous nephropathy was 9.89% and minimal change disease was 0.93%, remarkably less. The most prevalent etiology of secondary GN was systemic lupus erythrematosus (SLE) (54.3%) followed by Henoch-Schönlein purpura (20.3%), diabetic nephropathy (6.6%), systemic vasculitides (4.0%), and amyloidosis (2.2%). Based on the study of biopsy materials obtained from 607 cases manifesting chronic renal failure, IgAN was identified as the most frequent cause (26.69%) of chronic renal failure.
