Renal failure and heart transplant

Wilbert S Aronow, William H Frishman
The 2017 American College of Cardiology/American Heart Association hypertension guidelines diagnose hypertension if systolic blood pressure (SBP) is ≥ 130 mmHg or diastolic blood pressure (DBP) is ≥ 80 mmHg. Increased BP is SBP 120-129 mmHg with DBP < 80 mmHg. Lifestyle measures should be used to treat individuals with increased BP. Lifestyle measures plus BP-lowering drugs should be used for secondary prevention of recurrent cardiovascular events in individuals with clinical cardiovascular disease (coronary heart disease, congestive heart failure, or stroke) and an average SBP ≥ 130 mmHg or an average DBP ≥ 80 mmHg...

Antibody-mediated rejection is currently the leading cause of transplant failure. Prevailing dogma predicts that B cells differentiate into anti-donor-specific antibody (DSA)-producing plasma cells only with the help of CD4+ T cells. Yet, previous studies have shown that dependence on helper T cells decreases when high amounts of protein antigen are recruited to the spleen, two conditions potentially met by organ transplantation. This could explain why a significant proportion of transplant recipients develop DSA despite therapeutic immunosuppression...

OBJECTIVES: Primary graft dysfunction (PGD) is a devastating complication and the most common cause of early death following a heart transplant. The goal of this study was to report our experience of using mechanical circulatory support to manage severe PGD. METHODS: Following 208 heart transplants performed between January 2007 and May 2017, 14 (6.7%) patients presented with severe PGD. We provided haemodynamic support using the following approaches: a venoarterial extracorporeal membrane oxygenation device, left ventricular assist device, right ventricular assist device and biventricular assist device...

An effectively functioning arteriovenous fistula is the life line for patients on long-term hemodialysis, and for most an upper limb, native vessel fistula has significant short- and long-term advantages. There are, however, situations where a fistula has deleterious effects, including the relatively uncommon problem of severe heart failure exacerbated in particular by high-flow fistulas. There is also increasing evidence that a fistula can add to the already high burden of cardiovascular risk in patients with advanced kidney disease, including by promoting water and salt retention, and by inducing or worsening left ventricular hypertrophy...

Pediatric heart transplantation is standard of care for children with end-stage heart failure. The diverse age range, diagnoses, and practice variations continue to challenge the development of evidence-based practices and new technologies. Outcomes in the most recent era are excellent, especially with the more widespread use of ventricular assist devices (VADs). Waitlist mortality remains high and knowledge of risk factors for death while waiting and following transplantation contributes to decision-making around transplant candidacy and timing of listing...

BACKGROUND: Peritoneal dialysis (PD) is one of the corner stones of renal replacement therapy and should be strongly considered if preemptive kidney transplantation is not available. SUMMARY: There are several initiatives that may help the growth in the use of PD around the world. First, PD is an underused and valuable option in patients with heart failure and the chronic cardiorenal syndrome, especially in those with frequent hospitalizations despite optimal medical therapy...

INTRODUCTION The N terminal prohormone of brain natriuretic peptide (NT proBNP) is secreted by cardiomyocytes in response to increased wall stress resulting from pressure and volume overload. The modified Model for End Stage Liver Disease (modMELD) scale reflects the systemic effect of heart failure (HF), which includes end-organ congestion and subsequent hepatic and renal dysfunction. OBJECTIVES The aim of this study was to assess the prognostic accuracy of NT proBNP and the modMELD score, as well as to compare their usefulness in the risk stratification of patients with end-stage HF awaiting orthotopic heart transplantation (OHT)...

Induced pluripotent stem cells (iPSCs) avoid many of the restrictions that hamper the application of human embryonic stem cells: limited availability of source material due to legal restrictions in some countries, immunogenic rejection and ethical concerns. Also, the donor's clinical phenotype is often known when working with iPSCs. Therefore, iPSCs seem ideal to tackle the two biggest tasks of regenerative medicine: degenerative diseases with genetic cause (e.g., Duchenne's muscular dystrophy) and organ replacement in age-related diseases (e...

AIMS: Mineralocorticoid receptor antagonists (MRAs) have been demonstrated to improve outcomes in reduced ejection fraction heart failure (HFrEF) patients. However, MRAs added to conventional treatment may lead to worsening of renal function and hyperkalaemia. We investigated, in a population-based analysis, the long-term effects of MRA treatment in HFrEF patients. METHODS AND RESULTS: We analysed data of 6046 patients included in the Metabolic Exercise Cardiac Kidney Index score dataset...

Hepatitis C-induced cholestatic hepatitis is a well-known fatal complication of postorthotropic liver transplantation and prolonged immunosuppression. Recent studies on direct-acting antiviral agents have shown promising results in terms of morbidity and mortality of this condition in postorthotropic liver, heart, and renal transplant patients. However, hepatitis C-induced cholestatic hepatitis remains a highly fatal condition in non-transplant patients. We report the first-ever use of the oral direct-acting antiviral combination, elbasvir and grazeprevir, in the treatment of a non-liver transplant patient with cholestatic hepatitis...

Late allograft failure is characterized by cumulative subclinical insults manifesting over many years. Although immunomodulatory therapies targeting host T cells have improved short-term survival rates, rates of chronic allograft loss remain high. We hypothesized that other immune cell types may drive subclinical injury, ultimately leading to graft failure. We collected whole-genome transcriptome profiles from 15 independent cohorts composed of 1,697 biopsy samples to assess the association of an inflammatory macrophage polarization-specific gene signature with subclinical injury...

Background: Patients starting renal replacement therapy (RRT) for end-stage renal disease often present with one or more co-morbidities. This study explored the prevalence of co-morbidities in patients who started RRT in Europe during the period from 2005 to 2014. Methods: Using data from patients aged 20 years or older from all 11 national or regional registries providing co-morbidity data to the European Renal Association - European Dialysis and Transplant Association Registry, we examined the prevalence of the following co-morbidities: diabetes mellitus (DM) (primary renal disease and/or co-morbidity), ischaemic heart disease (IHD), congestive heart failure (CHF), peripheral vascular disease (PVD), cerebrovascular disease (CVD) and malignancy...

Peripheral blood stem cell transplantation (PBSCT) offers a curative option for sickle cell disease (SCD). Although HLA-matched sibling transplantation is promising, the vast majority of patients lack such a donor. We sought to develop a novel nonmyeloablative HLA-haploidentical PBSCT approach that could safely be used for patients with severe organ damage. Based on findings in our preclinical model, we developed a phase 1/2 trial using alemtuzumab, 400 cGy total body irradiation, and escalating doses of posttransplant cyclophosphamide (PT-Cy): 0 mg/kg in cohort 1, 50 mg/kg in cohort 2, and 100 mg/kg in cohort 3...

BACKGROUND: Human leukocyte antigen (HLA) was important biological barrier to a successful transplantation. Quantitative evaluations of the effect of HLA mismatching on heart, liver, umbilical cord blood, and hematopoietic stem cell transplantation, have previously been reported. In new era of immunosuppression, the reported magnitude effect of HLA mismatching on survival outcomes of kidney transplantation was controversial. In addition, the current kidney allocation guideline recommendations in different countries were inconsistent in term of HLA mismatching...

BACKGROUND: Calcium channel blocker (CCB) or two renin angiotensin aldosterone system blockades (RAAS), angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs), are major potent and prevalently used as initial antihypertensive agents for mild to moderate hypertension, but no uniform agreement as to which antihypertensive drugs should be given for initial therapy, especially among chronic kidney disease (CKD) patients. DESIGN: A systematic review and meta-analysis comparing CCBs and the two RAAS blockades for hypertensive patients with CKD stage 3 to 5D...

Thoracic endovascular repair (TEVAR) is an effective treatment for type B aortic dissection (TBAD). Here, we evaluated the early-midterm effectiveness and safety of TEVAR for treating TBAD patients after renal transplantation. Six patients with TBAD treated with TEVAR after renal transplantation were recruited between February 2012 and December 2016. They were then followed up with clinical examinations and computed tomography angiography (CTA). TEVAR was successfully performed in all patients (100%), and the primary tear sites were well covered by stents with or without coverage of the left subclavian artery...

Spirituality is a difficult concept to define, one that is often understood differently by different cultures and religious communities. Illness constitutes a dramatic change in the ongoing flow and norms of a person's life, raising questions of the value or meaning of life, questions of self-worth, and questions of forgiveness, to ourselves and others. The profession of spiritual care comes to provide support in these areas. Originally focused on religious care, the profession has shifted to providing care for general spiritual well-being, where professionals care for all patients regardless of religion...
