Smoking is associated with unfavourable outcome in solid organ transplant recipients. Nicotine may predispose to kidney injury by increasing oxidative stress. We hypothesized that former smoking negatively affects graft outcome in kidney transplant recipients and especially those with delayed graft function (DGF). We included adult recipients of a kidney transplant between January 1(st) 2003 and October 1(st) 2015 at Ghent University Hospital and recorded outcomes until October, 31(st) 2015. We used Kaplan-Meier and multivariable Cox proportional hazard analysis to examine the relationship between former smoking at the time of transplantation and the incidence of 10-year graft loss with and without censoring for death in 1013 participants...

Several antipsychotics and antidepressants have been associated with QTc prolongation or other ECG alterations, but their impact is still debated and other risk factors are known to affect QTc. We investigated the effect of antidepressants and antipsychotics on QTc and other ECG intervals/waves in three samples. Two discovery samples (cross-sectional sample n=145 and prospective sample n=68, naturalistic treatment) and a replication prospective sample (CATIE, n=515, randomized treatment) were analysed. In both prospective samples, baseline/follow-up changes in ECG parameters were analysed in relation to the number of psychotropic drugs stratified according to their known cardiovascular risk...

Renal operationally tolerant patients (TOL) display a defect in B cell differentiation, with a deficiency in plasma cells. Recently described, T follicular helper cells (Tfh) play a critical role in B cell differentiation. We analyzed blood Tfh subsets in TOL and transplanted patients with stable graft function under immunosuppression (STA). We observed a reduced proportion of blood activated and highly functional Tfh subsets in TOL, without affecting Tfh absolute numbers. Functionally, Tfh from TOL displayed a modified gene expression profile, failed to produce IL-21 and were unable to induce IgG production by naive B cells...

Costimulation blockade (CoB) via belatacept is a lower morbidity alternative to calcineurin inhibitor (CNI)-based immunosuppression. However, it has higher rates of early acute rejection. These early rejections are mediated in part by memory T cells, which have reduced dependence on the pathway targeted by belatacept, and increased adhesion molecule expression. One such molecule is Leukocyte Function Associated Antigen (LFA)-1. LFA-1 exists in two forms, a commonly expressed, low-affinity form, and a transient, high-affinity form, expressed only during activation...

Gentamicin nephrotoxicity accounts for 10-15% of all cases of acute renal failure. Several natural antioxidants were found to be effective against drug-induced toxicity. The possible protective effects of lycopene (Lyc) and rosmarinic acid (RA) alone or combined on gentamicin (Gen) induced renal cortical oxidative stress, apoptosis and autophagy were evaluated. Sixty three rats were randomly divided into seven groups named: control, group II received RA 50 mg/kg/day, group III received Lyc 4 mg/kg/day, group IV received Gen 100 mg/kg/day, group V (RA + Gen), group VI (Lyc + Gen) and group VII (RA + Lyc + Gen)...

The elderly population can be divided into three distinct age groups: 65-74 years (young-old), 75-84 years (middle-old), and 85+ years (old-old). Despite evidence of a shift in leading causes for mortality in the elderly from infectious diseases to chronic conditions, infections are still a serious cause of death in this population. These patients are at increased risk due to weakened immune systems, an increased prevalence of underlying comorbidities, and decreased physiologic reserves to fight infection. Additionally, elderly patients, especially adults in institutional settings, are at an increased risk of colonization and subsequent infection with methicillin-resistant Staphylococcus aureus at a rate that is five times higher than in younger individuals, causing an increase in empiric and definitive vancomycin use...

Heart failure patients who undergo cardiac surgery are exposed to significant perioperative complications and high mortality. We herein review the literature concerning preoperative optimization of these patients. Salient findings are that end-organ dysfunction and medication should be optimized before surgery. Specifically: (1) reversible causes of anemia should be treated and a preoperative hemoglobin level of 100 g/L obtained; (2) renal function and volume status should be optimized; (3) liver function must be carefully evaluated; (4) nutritional status should be assessed and cachexia treated to achieve a preoperative albumin level of at least 30 g/L and a body mass index > 20; and (5) medication adjustments performed, such as withholding inhibitors of the renin-angiotensin-aldosterone system before surgery and continuing, but not starting, β-blockers...

Over 50% of adults with HIV exhibit some form of HIV-associated neurocognitive disorder, ranging from mild asymptomatic neurocognitive impairment to HIV-associated dementia. As adults age with HIV and become susceptible to cardiovascular and metabolic comorbidities, the prevalence and severity of such neurocognitive disorders are likely to increase. With compromised renal and hepatic functioning often accompanying HIV, pharmaceutical interventions to address such neurocognitive disorders may not be the best strategy and are not without risks...

Aortic stenosis is one the most frequent valvular diseases in developed countries, and its impact on public healthcare resources and assistance is increasing. A substantial proportion of elderly patients with severe aortic stenosis is frequently not eligible for surgery because of advanced age, frailty and multiple comorbidities. Transcatheter aortic valve implantation (TAVI) enables the treatment of very elderly patients at high or prohibitive surgical risk considered ineligible for surgery and with an acceptable life expectancy...

Acute kidney injury (AKI) is frequently observed after DBD liver transplantation (LT) and associated with impaired recipient survival and chronic kidney disease. Hepatic ischemia/reperfusion injury (IRI) is suggested to be an important factor in this process. The postreperfusion syndrome (PRS) is the first manifestation of severe hepatic IRI directly after reperfusion. We performed a retrospective study on the relation between hepatic IRI and PRS and their impact on AKI in 155 DBD LT recipients. Severity of hepatic IRI was measured by peak postoperative AST levels and PRS was defined as >30% decrease in MAP ≥1 minute <5 minutes after reperfusion...

The Na(+) -ATPase, a secondary pump in the proximal tubule, is only weakly responsive to angiotensin II in adult offspring exposed perinatally to high Na(+) intake. We have investigated whether the offspring from mothers given 0.3 M NaCl show an ineffective angiotensin II action to increase in blood pressure. It was hypothesized that functional alterations at adult life are associated with the number angiotensin II-positive cells in the developing kidney, with increased oxidative stress in maternal/foetal organs, or with morphometrical changes in placentas...

Non-selective betablockers (NSBBs) remain the cornerstone of medical treatment of portal hypertension. The evidence for their efficacy to prevent variceal bleeding is derived from prospective trials, which largely excluded patients with refractory ascites and renal failure. In parallel to the increasing knowledge on portal hypertension-induced changes in systemic hemodynamics, cardiac function, and renal perfusion, emerging studies have raised concerns about harmful effects of NSBBs. Clinicians are facing an ongoing controversy on the use of NSBBs in patients with advanced cirrhosis...

The combination of dabrafenib and trametinib is a standard of care for the management of BRAF mutant metastatic melanoma. Clinical trials excluded patients with end-stage kidney disease (ESKD) and as such no data are available regarding the safety, efficacy and pharmacokinetics of these drugs in such patients. Here, we present the case of a 78 year-old male patient with ESKD managed with haemodialysis (HD), treated with dabrafenib and trametinib at reduced doses. The patient has had a partial response, and this response continues at 9 months since our last follow up without any dose escalation...

Background Combined liver-kidney transplantation (CLKT) is well-established as a definitive therapy with the potential to provide complete recovery for certain liver-kidney diseases, although the results might be contingent on the cause of transplantation. The purposes of the present study were to review the long-term outcome of renal allografts in CLKT patients from single living donors and to investigate the beneficial factors, compared with solitary renal transplantation. Materials and Methods Thirteen patients underwent sequential liver (LTx) and kidney (KTx) transplantations from single living donors...

BACKGROUND: Many aspects of post-transplant monitoring of donorspecific (DSA) and non-donorspecific (nDSA) anti-HLA antibodies on renal allograft survival are still unclear. Differentiating them by their ability to bind C1q may offer a better risk assessment. METHODS: We retrospectively investigated the clinical relevance of de novo C1q-binding anti-HLA antibodies on graft outcome in 611 renal transplant recipients. Acute rejection (AR), renal function and graft survival were assessed within a mean follow-up of 6...

Calcineurin inhibitors (CNI) are the mainstay of immunosuppression after liver transplantation (LT), but CNIs are associated with significant nephrotoxicity. Recently, mTOR inhibitors such as sirolimus and everolimus (EVR) have been used with or without CNIs in LT recipients for their renal-sparing effect. We conducted a systematic review and meta-analysis of randomized controlled trials (RCT) that examined the effect of EVR with CNI minimization or withdrawal on renal function in LT recipients. RCT of primary adult LT recipients with baseline GFR >30 mL/min who received EVR with CNI minimization or withdrawal were included...

It is now widely accepted that in order to improve long-term graft function and survival, a more personalized immunosuppressive treatment of transplant patients according to the individual anti-donor immune response status is needed. This applies to the identification of potentially "high-risk" patients likely to develop acute rejection episodes or display an accelerated decline of graft function, patients who might need immunosuppression intensification, and operationally tolerant patients suitable for immunosuppression minimization or weaning off...

The assessment of the glomerular filtration rate (GFR) is essential to judge renal function in clinical practice. Estimated GFR based on serum creatinine concentration is useful as a "first line" test of kidney function, whereas measured GFR using urinary or plasma clearance of exogenously applied markers of filtration provides more accurate information and allows conclusions on the function of the filtration barrier and the tubular reabsorptive capacity (Stevens & Levey 2009). Defects of the glomerular filtration barrier may impair size selectivity and cause proteinuria, leading to chronic kidney disease...

For more than sixty years, warfarin was the only oral anticoagulation agent available for use in the United States. In many recent clinical trials, several direct oral anticoagulants (DOACs) demonstrated similar efficacy with an equal or superior safety profile; with some other notable benefits. The DOACs have lower inter- and intra-patient variability, much shorter half-lives, and less known drug-drug and drug-food interactions as compared to warfarin. Despite these demonstrated benefits, the use of DOACs have not gained uniform acceptance because of lack of supportive data in special patient populations, including recipients of solid organ transplants maintained on immunosuppression...
