Correlation between Dt/V derived from ionic dialysance and blood-driven Kt/V of urea in African-American hemodialysis patients, based on body weight and ultrafiltration volume.

Background: The Dt/V obtained by using ionic dialysance (D) as a surrogate for urea clearance (K) is a well-validated adjunct measure of hemodialysis adequacy, with a variable level of correlation with urea-based Kt/V. However, this correlation has not been examined based on patients' body size and ultrafiltration (UF) volume during the dialysis session.

Methods: Simultaneous evaluations of online Dt/V and single-pool variable-volume urea Kt/V were made.

Preliminary experience with cinacalcet use in persistent secondary hyperparathyroidism after kidney transplantation.

Background: There is limited experience with the use of cinacalcet in the treatment of persistent secondary hyperparathyroidism after kidney transplantation.

Methods: We retrospectively analyzed our experience in 18 renal allograft recipients who initiated cinacalcet therapy from 1 month to 23 years (median 3 years) posttransplantation and were maintained on the drug for 6 months. The daily dose was titrated from 30 mg up to a maximum of 180 mg to achieve a reduction in serum intact parathyroid hormone (PTH) levels.

Predictive value of human leucocyte antigen epitope matching using HLAMatchmaker for graft outcomes in a predominantly African-American renal transplant cohort.

The HLAMatchmaker program is based on the donor/recipient comparison of the polymorphic triplet amino-acid sequences of the antibody-accessible regions on the human leucocyte antigen (HLA) molecule. The previous reports on its predictive value for renal allograft outcomes are conflicting. We conducted a retrospective study in a predominantly African-American (AA) cohort (N = 101, 94% AA).

Case report: recurrent heart failure with preserved ejection fraction but markedly elevated BNP in a 51-year-old female on hemodialysis with oversized AV fistula.

We hereby report a case that appeared to have had recurrent clinical heart failure secondary to high-output state due to oversized arteriovenous fistula. Patient started to have dyspnea on exertion approximately 4 months after the creation of the fistula, and subsequently had two episodes of heart failure exacerbation. On both occasions, she had normal left ventricular systolic function as demonstrated by echocardiogram.

Induction therapy with basiliximab versus Thymoglobulin in African-American kidney transplant recipients.

Background: It has been suggested that the use of antilymphocyte induction therapy in African-American (AA) renal transplant recipients reduces the risk of acute rejection (AR) and improves graft survival. It is not clear whether the efficacy of basiliximab (BSX) is different from that of Thymoglobulin (ATG) in this regard.

Methods: We retrospectively assessed the effect of induction therapy with BSX versus ATG in 88 AA renal allograft recipients receiving transplants at our center between July 2001 and June 2003 and followed for 19+/-7 months.

West Nile virus encephalitis: an emerging disease in renal transplant recipients.

West Nile virus (WNV) has emerged as an important cause of several outbreaks of febrile illness and encephalitis in North America over the past few years. The most common manifestation in symptomatic patients is a transient febrile illness. Neuroinvasive disease, that can be fatal, occurs most often in elderly and immunocompromised hosts.

Sirolimus-induced angioedema.

Sirolimus (SRL) is a macrolide immunosuppressant that has gained widespread use in organ transplantation. Its full spectrum of side-effects is yet to be defined. We describe herein three cases of SRL-induced angioedema (AE) in African-American (AA) primary renal allograft recipients who received SRL in combination with mycophenolate mofetil and steroids.

Gabapentin-induced hypoglycemia in a long-term peritoneal dialysis patient.

An end-stage renal disease patient on long-term peritoneal dialysis was admitted with dizziness, fatigue, hypoglycemia, and hypotension. The hypotension resolved with intravenous normal saline, but the hypoglycemia persisted for 3 days despite an intravenous dextrose drip and discontinuation of gabapentin. The patient became normoglycemic on the fourth day of admission.

Lipid abnormalities and renal disease: is dyslipidemia a predictor of progression of renal disease?

Dyslipidemia is a cardiovascular disease (CVD) risk factor that is associated with enhanced atherosclerosis and plaque instability. Renal insufficiency is associated with abnormalities in lipoprotein metabolism in both the early and the advanced stages of chronic renal failure. These include alterations in apolipoprotein A (apo A)- and B- containing lipoproteins, high-density lipoproteins, and triglycerides.
