Prevalence of various comorbidities among veterans with chronic kidney disease and its comparison with other datasets.

Chronic kidney disease (CKD) has a complicated interrelationship with various comorbidities. The purpose of this study was to describe the prevalence of various comorbidities among veterans with CKD and compare it with other datasets like Kidney Early Evaluation Program (KEEP), National Health and Nutrition Examination Survey (NHANES) and Medicare. Patients who had at least one outpatient visit in year 2007 (1 January 2007 to 31 December 2007) were included in the study (n =  75,787).

Association of Extrarenal Adverse Effects of Posttransplant Immunosuppression With Sex and ABCB1 Haplotypes.

Extrarenal adverse effects (AEs) associated with calcineurin inhibitor (CNI) and mycophenolic acid (MPA) occur frequently but are unpredictable posttransplant complications. AEs may result from intracellular CNI accumulation and low activity of P-glycoprotein, encoded by the ABCB1 gene. Since ABCB1 single nucleotide polymorphisms (SNPs) and sex influence P-glycoprotein, we investigated haplotypes and extrarenal AEs.

Effect of steroid-free low concentration calcineurin inhibitor maintenance immunosuppression regimen on renal allograft histopathology and function.

Background: The most common cause of late kidney transplant failure is insidiously progressive renal dysfunction associated with organ scarring and fibrosis. Advanced donor age, delayed graft function, calcineurin toxicity and repeated acute rejection episodes are risk factors for this pathophysiology.

Methods: We employed 3, 12 and 24 months surveillance renal biopsies, scored using the Chronic Allograft Damage Index (CADI), with periodic estimates of glomerular filtration rate (eGFR) to assess the effect of a steroid-free maintenance immunosuppression regimen on allograft histology and function.

CKD in MYH9-related disorders.

MYH9-related disorders are rare causes of chronic kidney disease (CKD) presenting as chronic glomerulonephritis and derive from mutations of the MYH9 gene, which encodes for the nonmuscle myosin heavy chain IIA. These disorders are autosomal dominant and include May-Hegglin anomaly and Sebastian, Fechtner, and Epstein syndromes. Diagnosis of these disorders is made first in early childhood because of the characteristic peripheral-blood smear findings of thrombocytopenia, giant platelets, and variably detected basophilic cytoplasmic inclusion bodies in leukocytes.

Cross Reactive Epitope Group antibodies in sensitized kidneys transplant recipients was associated with early acute Antibody Mediated Rejection.

Background: Antibody Mediated Rejection (AMR) is a major cause of early graft loss, graft dysfunction, and chronic allograft nephropathy. Patients with elevated pre-transplant Panel Reactive Antibodies (PRA) are at much higher risk to develop AMR. We, retrospectively, studied the attack rate of AMR in sensitized recipients and evaluated whether preformed antibodies to donor Cross Reactive Epitope Group (CREG) and/or choice of induction immunosuppressive agent affected the frequency of this complication.

Nephrogenic systemic fibrosis.

Nephrogenic systemic fibrosis is a recently diagnosed disease that occurs in patients with chronic kidney disease and acute renal failure. The patients develop skin thickening and fibrosis which is usually symmetrical, and typically of the upper and lower extremities. In some cases the progression is rapid leading to joint contractures confining the patient to a wheelchair.
