Cardiovascular disease in the kidney transplant recipient: epidemiology, diagnosis and management strategies.

Kidney transplantation (KT) is the optimal therapy for end-stage kidney disease (ESKD), resulting in significant improvement in survival as well as quality of life when compared with maintenance dialysis. The burden of cardiovascular disease (CVD) in ESKD is reduced after KT; however, it still remains the leading cause of premature patient and allograft loss, as well as a source of significant morbidity and healthcare costs. All major phenotypes of CVD including coronary artery disease, heart failure, valvular heart disease, arrhythmias and pulmonary hypertension are represented in the KT recipient population. Pre-existing risk factors for CVD in the KT recipient are amplified by superimposed cardio-metabolic derangements after transplantation such as the metabolic effects of immunosuppressive regimens, obesity, posttransplant diabetes, hypertension, dyslipidemia and allograft dysfunction. This review summarizes the major risk factors for CVD in KT recipients and describes the individual phenotypes of overt CVD in this population. It highlights gaps in the existing literature to emphasize the need for future studies in those areas and optimize cardiovascular outcomes after KT. Finally, it outlines the need for a joint 'cardio-nephrology' clinical care model to ensure continuity, multidisciplinary collaboration and implementation of best clinical practices toward reducing CVD after KT.

Early findings of prospective anti-HLA donor specific antibodies monitoring study in pancreas transplantation: Indiana University Health Experience.

The significance of donor-specific antibodies (DSA) is not well known in the setting of pancreas transplantation. Since December 2009, we prospectively followed pancreas transplant patients with single-antigen-luminex-bead testing at one, two, three, six, and then every six months for the first two yr. Thirty-five of the 92 patients that underwent pancreas transplantation (13 pancreas-alone [PTA], 20 with a kidney [SPK], and two after a kidney [PAK]) agreed to participate in study. Median age at transplant was 45 yr and follow-up was 23 months. Majority were Caucasian (n = 33) and male (n = 18). Rabbit anti-thymocyte globulin induction was used. Median HLA-mismatch was 4.2 ± 1.1. Eight patients (7SPK, 1PAK) developed post-transplant DSA at median follow-up of 76 d (26-119), 1 SPK had pre-formed DSA. Seven patients had both class I and class II DSA, one with class I and one with class II only. Mean peak class I DSA-MFI was 3529 (±1456); class II DSA-MFI was 5734 (±3204) whereas cumulative DSA MFI (CI + CII) was 9264 (±4233). No difference was observed in the patient and donor demographics among patients with and without DSA. One patient in non-DSA group developed acute cellular rejection of pancreas. From our data it appears that post-transplant DSA in pancreas allograft recipients may not impact the early-pancreatic allograft outcomes. The utility of prospective DSA monitoring in pancreatic transplant patients needs further evaluation and long-term follow-up.
