BACKGROUND: Cancer immunotherapy, such as anti-cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and anti-programmed death 1 (PD-1), has revolutionized the treatment of malignancies by engaging the patient's own immune system against the tumor rather than targeting the cancer directly. These therapies have demonstrated a significant benefit in the treatment of melanomas and other cancers. SUMMARY: In order to provide an extensive overview of the renal toxicities induced by these agents, a Medline search was conducted of published literature related to ipilimumab-, pembrolizumab-, and nivolumab-induced kidney toxicity...

BACKGROUND: Most studies that have assessed the predictors of recurrent IgA nephropathy (IgAN) in the renal allograft have focused on post-transplant features. Identifying high-risk pre-transplant features of IgAN is useful for counseling patients and may help in tailoring post-transplant immunosuppression. METHODS: We investigated the pre-transplant clinical and biopsy features of 62 patients with IgAN who received transplants at Columbia University Medical Center from 2001 to 2012 and compared the characteristics and outcomes of patients with IgAN recurrence to those without recurrence...

BACKGROUND: Quantitative dose-response associations between fibroblast growth factor 23 (FGF23) and risks of mortality, cardiovascular disease (CVD), and renal events in chronic kidney disease (CKD) are not known. This study aimed to summarize and quantify the predictive effects of FGF23 among the pre-dialysis CKD stages 1-5 population. METHODS: Data sources included PubMed, EMBASE, and Web of Science. Prospective cohort studies assessing the associations between FGF23 and all-cause mortality, CVD, and renal events in CKD patients were selected...

BACKGROUND: The role of high density lipoprotein-raising interventions in addition to statin therapy in patients with diabetes remains controversial. Chronic kidney disease (CKD) is a strong modifier of cardiovascular (CV) outcomes. We therefore investigated the impact of CKD status at baseline on outcomes in patients with diabetes randomized to standard statin or statin plus fenofibrate treatment in the Action to Control Cardiovascular Risk in Diabetes (ACCORD) lipid trial. METHODS: Among 5,464 participants in the ACCORD lipid trial, 3,554 (65%) were free of CKD at baseline, while 1,910 (35%) had mild to moderate CKD...

BACKGROUND: Daprodustat (GSK1278863) is an oral hypoxia-inducible factor prolyl hydroxylase inhibitor being developed for treatment of anemia associated with chronic kidney disease (CKD). The effect of daprodustat in Japanese CKD patients with anemia has not been previously investigated. METHODS: We evaluated the relationship between daprodustat dose and hemoglobin response in Japanese patients on hemodialysis (HD) with anemia in a 4-week, phase II, double-blind, placebo-controlled study...

BACKGROUND: We evaluated the prevalence, determinants and prognosis value of pulmonary hypertension (PH) in non-dialysis chronic kidney disease (CKD) patients. METHODS: This is a prospective study with stages 3-5 non-dialysis-dependent CKD patients. PH was estimated by Doppler echocardiography and defined as a pulmonary artery systolic pressure above 35 mm Hg. RESULTS: Three hundred fifty-three patients were recruited, of whom 94 (26.6%) had PH...

BACKGROUND: Low serum bicarbonate concentrations are associated with mortality and kidney disease progression. Data regarding associations between bicarbonate and cardiovascular disease (CVD) are scarce. METHODS: We performed a cohort study of 6,229 adult participants from the Multi-Ethnic Study of Atherosclerosis, a community-based cohort free of CVD at baseline. Serum bicarbonate was measured at baseline. Cardiovascular outcomes were defined as: (1) subclinical CVD (left ventricular mass [LVM] and aortic pulse pressure [PP] measured at baseline), (2) incident atherosclerotic cardiovascular events (CVE; composite of myocardial infarction, resuscitated cardiac arrest, stroke, coronary heart disease death, and stroke death), and (3) incident heart failure...

BACKGROUND: Despite a previous study showing that PINCH-1 exerts an important role in regulating TGF-β1-mediated mesenchymal transition through its interaction with integrin-linked kinase, relatively little is known about the role of PINCH in the obstructive nephropathy. METHODS: To construct a rat model of renal interstitial fibrosis and obstructive nephropathy, unilateral ureteral obstruction (UUO) was used. Hematoxylin and eosin and Masson staining were used in histologic examinations...

BACKGROUND: Non-adherence to medication is a well-studied and known cause of late allograft loss, but it is difficult to measure and prospectively monitor. The aim of this study was to assess if appointment non-adherence was correlated with medication non-adherence and a predictor of graft outcomes. METHODS: This was a longitudinal cohort study that used the National United States Renal Data System and veterans affairs health records data with time-to-event analyses conducted to assess the impact on graft and patient survival...

BACKGROUND: Simple renal cysts may be an early marker of renal disease. We investigated whether simple cysts in donor kidney are associated with the decline of allograft function in living donor kidney transplantation. METHODS: We retrospectively reviewed records of donors and recipients from 716 living donor kidney transplants performed between April 2007 and April 2015 in our hospital. Ninety-one donors with renal cysts and 64 recipients with cysts in donor kidney were noted...

BACKGROUND: Patients with end-stage renal disease (ESRD) are at a high risk of cardiovascular mortality (CVM). In patients with ESRD, arterial stiffness increases at an earlier age when compared to the general population and this contributes to the overall risk of cardiovascular mortality. The main objective of this study was to clarify the interplay between age and cardiovascular alterations in ESRD. METHODS: Prospective, observational cohort study initiated in April 1987 until the end of 1998 with events recorded until the end of the year 2000 at the F...

BACKGROUND: The survival rates of renal transplant children are indeed on the rise, but it is still important to ensure that there is optimal renal function in these children in all their future growing years. The number of functioning nephrons and the graft ability to adapt to an increasing demand during body growth seem to be the most important factors for long-term allograft function. This study examined the long-term change in the glomerular filtration rate in a pediatric kidney transplant cohort and the importance of the recipient and donor ages in predicting transplant outcome...

BACKGROUND: Intravenous (IV) iron preparations are widely used in the treatment of anemia in patients undergoing hemodialysis (HD). All IV iron preparations carry a risk of causing hypersensitivity reactions. However, the pathophysiological mechanism is poorly understood. We hypothesize that a relevant number of these reactions are mediated by complement activation, resulting in a pseudo-anaphylactic clinical picture known as complement activation-related pseudo allergy (CARPA). METHODS: First, the in-vitro complement-activating capacity was determined for 5 commonly used IV iron preparations using functional complement assays for the 3 pathways...

BACKGROUND: Vitamin D analogs and calcimimetics are used to manage secondary hyperparathyroidism (SHPT) in dialysis patients. DP001 is an oral vitamin D analog that suppresses parathyroid hormone (PTH) in uremic rats, osteopenic women, and hemodialysis patients. The safety and effectiveness of DP001 suppressing PTH in dialysis patients previously managed with active vitamin D with or without a calcimimetic are presented. METHODS: A multicenter, randomized, double-blind study compared DP001 to placebo in hemodialysis patients with serum-intact PTH (iPTH) ≥300 pg/ml...

BACKGROUND: The association of renal cancer with viral hepatitis infection remains unclear. Using an insurance data set, this population-based case-control study evaluated the association of renal cancer with chronic hepatitis virus infection in an endemic area of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection. METHODS: We enrolled 17,747 patients with renal cancer during the period from 2000 to 2011 from the National Health Insurance Research Database of Taiwan...
