The therapeutic potential of a novel, targeted-release formulation oral budesonide (Nefecon) for the treatment IgA nephropathy (IgAN) was first demonstrated by phase 2b NEFIGAN trial. To verify these findings, 3 NefigArd trial tested efficacy and safety nine months with Nefecon (16 mg/d) versus placebo in adult patients primary IgAN at risk progressing to kidney failure (ClinicalTrials.gov: NCT03643965). NefIgArd multicenter, randomized, double-blind, placebo-controlled two-part In Part A,...

Daprodustat is a hypoxia-inducible factor prolyl hydroxylase inhibitor (HIF-PHI) being investigated for the treatment of anemia CKD. In this noninferiority trial, we compared daprodustat administered three times weekly with epoetin alfa (epoetin) in patients on prevalent hemodialysis switching from prior erythropoiesis-stimulating agent (ESA).Patients baseline hemoglobin 8-11.5 g/dl receiving an ESA were randomized 2:1 to (n=270) or conventional (n=137) 52 weeks. Dosing algorithms aimed...

Abstract Hypertension is the leading risk factor for cardiovascular disease (CVD) worldwide. Despite availability of effective antihypertensive medications, control hypertension at a global level dismal, and consequently, CVD burden continues to increase. In response, countries in Latin America Caribbean are implementing HEARTS Americas, community‐based program that focuses on increasing secondary prevention through mitigation. One key pillar implementation standardized treatment protocol...

Spot urine samples with estimating equations have been used to assess individuals’ sodium (salt) intake in association health outcomes. There is large random and systematic error using this method spurious outcome associations. Substantial controversy has resulted from false claims the valid. Hence, World Hypertension League, International Society of Resolve Save Lives, supported by 21 other organizations, issued policy statement that strongly recommends research spot outcomes should not be...

Phosphate intoxication, manifested by hypocalcemic tetany and acute renal failure, may complicate bowel-cleansing preparations which contain phosphate. These are commonly used to prepare patients for various gastrointestinal procedures. Often, who receive these regimens at increased risk of phosphate intoxication from diseases slow transit or decrease excretion (renal insufficiency). We present a patient developed oliguric failure severe associated with phosphate-containing regimen.

Hypertension is one of the most important risk factors for cardiovascular disease. The Global Burden Disease Study in 2010 described hypertension as leading factor global disease burden, accounting 18% all deaths and 7% disability-adjusted life years.1 Furthermore, responsible 45% caused by ischemic heart 51% stroke.2 As death disability, requires a response.

Background. The insertion/deletion (I/D) angiotensin-converting enzyme (ACE) polymorphism has been established as a cardiovascular risk factor in some populations, but the association with essential hypertension is controversial. Predominantly diastolic (PDH), or narrow pulse pressure hypertension, shown to have increased peripheral resistance. Because DD genotype associated higher plasma ACE levels and angiotensin II activity, we genotyped PDH patients for I/D polymorphism. Methods....

The ability to reliably evaluate the impact of interventions and changes in hypertension prevalence control is critical if burden hypertension-related disease be reduced. Previously, a World Hypertension League Expert Committee made recommendations standardize reporting population blood pressure surveys. We have added those also provide modified from Pan American Health Organization expert meeting for "performance indicators" used clinical practices. Core indicators surveys are recommended...

Our laboratory previously cloned a novel rabbit gene ( Kcn1), expressed in kidney, heart, and aorta, predicted to encode protein with 58% amino acid identity the K channel Shaker Kv1.3 (Yao X et al. Proc Natl Acad Sci USA 92: 11711–11715, 1995). Because Kcn1 did not express well (peak current Xenopus laevis oocytes of 0.3 μA at +60 mV), human homolog (KCNA10) was isolated, its expression optimized oocytes. KCNA10 mediates voltage-gated + currents that exhibit minimal steady-state...
