Infectious diseases consult improves vaccination adherence in kidney transplant candidates.

BACKGROUND: Vaccines prevent infections and avoid related complications. Low rates in immunocompromised patients are concerning due to increased morbidity. Vaccinations are less effective when administered post-transplant and should be administered prior. We describe pre-transplant vaccination rates among kidney or kidney-pancreas transplant recipients. METHODS: Retrospective review including adults receiving kidney or kidney-pancreas allografts at Cleveland Clinic from October 2013 to October 2016. Pre-transplant vaccinations, serologies, and transplant data were collected. RESULTS: 393 patients were included; median age was 53 years with most (46%) being Caucasian males. Influenza vaccination rate was 48%; receipt of at least one pneumococcal vaccine was 77%. Vaccination rates were higher among dialysis patients for pneumococcal, hepatitis B, and varicella vaccines; rates were also higher with infectious diseases consults. CONCLUSIONS: Vaccination rates at our institution for kidney or kidney-pancreas transplant candidates are consistent with previous literature. Rates were higher for candidates with infectious diseases consults or receiving dialysis.

En Bloc Multivisceral and Kidney Transplantation in an HIV Patient: First Case Report.

The continual improvement in outcome with highly active antiretroviral therapy (HAART) for human immunodeficiency virus (HIV) infection and visceral transplantation for gut failure stimulated our interest in lifting HIV infection as a contraindication for intestinal and multivisceral transplantation. This report is the first to describe visceral transplantation in a patient with HIV infection. A HAART regimen was introduced in the setting of short-gut syndrome with successful suppression of HIV viral load. The indication for en bloc multivisceral and kidney transplantation was end-stage liver failure with portomesenteric venous thrombosis and chronic renal insufficiency. The underlying hepatic pathology was alcoholic and home parenteral nutrition-associated cirrhosis. Surgery was complicated due to technical difficulties with excessive blood loss and long operative time. The complex posttransplant course included multiple exploratory laparotomies due to serious intra-abdominal and systemic infections. Heavy immunosuppression was required to treat recurrent episodes of severe allograft rejection. Posttransplant oral HAART successfully sustained undetectable viral load. Unfortunately, the patient succumbed to sepsis 3 months posttransplant. With new insights into the biology of gut immunity, mechanisms of allograft tolerance, and HIV-associated immune dysregulation, successful outcome is anticipated, particularly in patients who are in need of isolated intestinal and less-organ-contained visceral allografts.

Performance of recalibrated ReFacto laboratory standard in the measurement of FVIII plasma concentration via the chromogenic and one-stage assays after infusion of recalibrated ReFacto (B-domain deleted recombinant factor VIII).

The use of ReFacto Laboratory Standard (RLS) in the one-stage clotting assay was proposed to reduce the underestimation of factor VIII (FVIII) plasma concentration after the infusion of 'ReFacto' (B-domain deleted recombinant FVIII) in haemophilia A patients. Both ReFacto and RLS were recently recalibrated, with the resulting materials containing approximately 20% more protein than the previous products. The aim of this study was to evaluate the performance of recalibrated RLS in the measurement of FVIII plasma concentration after the infusion of recalibrated ReFacto. In 13 severe haemophilia A patients, 25 IU kg(-1) of ReFacto were injected intravenously. Venous blood samples were collected at 0.25, 0.5, 1, 3, 6, 9, 24, 28 and 32 h after the end of the infusion. Pharmacokinetic parameters were measured for the chromogenic and one-stage assays using International Plasma Standard (IPS) and RLS for both assays and assuming a non-compartmental drug disposition. Comparisons among assays and standards were performed using anova. Pharmacokinetic estimates obtained with the chromogenic method were in agreement with those published in the literature. The one-stage method was confirmed to be more sensitive to lower plasma concentrations of FVIII. The measured maximum plasma concentration (C(max)) was slightly higher than theoretical values and independent of the assay used. C(max), area under the curve (AUC) and volume of distribution at steady state (V(ss)) presented non-significant differences among the methods and standards used. The clinical utility of RLS in the evaluation of FVIII concentration after the infusion of ReFacto seems to be reduced since recalibration of the product.
