Hyperkalemia

BACKGROUND: Asians bear a heavier burden of chronic kidney disease (CKD), a common comorbidity of type 2 diabetes mellitus (T2DM), than non-Asians. Nonsteroidal mineralocorticoid receptor antagonists (MRAs) have garnered attention for their potential advantages in renal outcomes. Nevertheless, the impact on diverse ethnic groups remains unknown. METHODS: The PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang database, and clinical trial registries were searched through August 2023 with the following keywords: nonsteroidal MRAs (finerenone, apararenone, esaxerenone, AZD9977, KBP-5074), CKD, T2DM, and randomized controlled trial (RCT)...

Glyphosate (GLP) is an active agent of GLP-based herbicides (GBHs), i.e., broad-spectrum and postemergent weedkillers, commercialized by Monsanto as, e.g., Roundup and RangerPro formulants. The GBH crop spraying, dedicated to genetically engineered GLP-resistant crops, has revolutionized modern agriculture by increasing the production yield. However, abusively administered GBHs' ingredients, e.g., GLP, polyoxyethyleneamine, and heavy metals, have polluted environmental and industrial areas far beyond farmlands, causing global contamination and life-threatening risk, which has led to the recent local bans of GBH use...

Heart failure (HF) is a prevalent clinical syndrome characterized by significant morbidity and is often precipitated by impaired left ventricular myocardial function. The condition can be categorized into two primary forms based on the ejection fraction (EF): Heart failure with preserved ejection fraction (HFpEF) and Heart failure with reduced ejection fraction (HFrEF). Evidence-based treatments for HF have been instrumental in reducing morbidity and mortality, particularly in patients with HFrEF. Mineralocorticoid receptor antagonists (MRAs) represent a cornerstone in the pharmacological management of HF, with a strong indication for use in HFrEF...

INTRODUCTION: Hypertension (HTN) is a co-morbidity that is commonly associated with heart failure with preserved ejection fraction (HFpEF). However, it remains unclear whether treatment of hypertension in HFpEF patients is associated with improved cardiovascular outcomes. AIM: The purpose of this meta-analysis is to evaluate the association of anti-hypertensive medical therapy with cardiovascular outcomes in patients with HFpEF. METHODS: We performed a database search for studies reporting on the association of anti-hypertensive medications with cardiovascular outcomes and safety endpoints in patients with HFpEF...

Globally, chronic kidney disease of unknown etiology (CKDu) has been recognized as an emerging cause contributing to the rise in chronic kidney disease (CKD). Nevertheless, in the Kingdom of Saudi Arabia, the epidemiology of CKDu remains understudied. The aim of this study was to assess the epidemiological, clinical, and laboratory characteristics of the CKDu population. From May 2021 to May 2022, a retrospective cross-sectional study was conducted on patients with Stage 4-5 CKD who presented to King Fahd Hospital in Jeddah...

Hyperkalaemia is one of the common electrolyte imbalances dealt with in the emergency department and is caused by extracellular accumulation of potassium ions above normal limits usually greater than 5.0-5.5 mmol/L. It is found in a total of 1-10% of hospitalised patients usually associated with chronic kidney disease and heart failure. The presentation can range from being asymptomatic to deadly arrhythmias. The appearance of symptoms depends on the rate of change rather than just the numerical values. The rare presentation includes periodic paralysis characterised by the sudden onset of short-term muscle weakness, stiffness or paralysis...

OBJECTIVE: This study aimed to assess the effect of banana intake during hemodialysis on serum potassium levels in maintenance hemodialysis (MHD) patients. METHODS: This study was a single-center, randomized controlled clinical trial conducted from September 15 to December 15, 2021, at a tertiary hospital in southern China. A total of 126 MHD patients were randomly assigned to either the intervention group ( n  = 64) or the control group ( n  = 62)...

INTRODUCTION: Several randomized controlled trials (RCTs) have examined mineralocorticoid receptor antagonists (MRAs) in heart failure (HF) with reduced ejection fraction (HFrEF). This systematic review and network meta-analysis (NMA) evaluated the comparative efficacy and safety of MRAs in HFrEF. MATERIALS AND METHODS: MEDLINE(Pubmed), Scopus, Cochrane and ClinicalTrials.gov were searched until April 8, 2024 for RCTs examining the efficacy and/or safety of MRAs in HFrEF...

Hyperkalemic periodic paralysis is a rare medical condition characterized by periods of extreme muscle weakness or paralysis. While most cases of hyperkalemic periodic paralysis are associated with a genetic channelopathy, cases of secondary hyperkalemic periodic paralysis can pose a challenge for medical personnel in terms of timely recognition. Identification of this medical emergency early in its course is essential to preventing cardiac and neurological sequelae. We report a case of a 58-year-old female who presented with stroke-like symptoms and was found to have secondary hyperkalemic periodic paralysis attributed to the excess consumption of potatoes, a potassium-rich food...

Pseudohypoaldosteronism type 1 is a rare genetic disorder characterized by salt wasting and resistance to mineralocorticoids due to mutations in the NR3C2 gene which codes for the aldosterone receptor proteins in the kidneys. This case study involves an infant who presented with poor growth and significant hyponatremia. There was improvement in growth and correction of hyponatremia with sodium supplementation, later found to carry a new genetic variant causing autosomal dominant pseudohypoaldosteronism type 1...

INTRODUCTION: The REVOLUTIONIZE I study aimed to characterize the relationships between medical nutrition therapy (MNT) and hyperkalemia recurrence in patients with stage 3-4 chronic kidney disease (CKD) and hyperkalemia who received MNT in real-world clinical practice.

BACKGROUND: Both high and low levels of serum potassium measurements are linked with a higher risk of adverse clinical events among patients with type 2 diabetes. The study was aimed at evaluating the implications of the various degrees of initial estimated glomerular filtration rate (eGFR) change on subsequent serum potassium homeostasis following sodium-glucose cotransporter-2 inhibitor (SGLT2i) initiation among patients with type 2 diabetes. METHODS AND RESULTS: We used medical data from a multicenter health care provider in Taiwan and recruited 5529 patients with type 2 diabetes with baseline/follow-up eGFR data available after 4 to 12 weeks of SGLT2i treatment from June 1, 2016, to December 31, 2018...

BACKGROUND: Angiotensin-converting enzyme inhibitors and angiotensin receptor blockers (ACEi/ARBs) can cause acute kidney injury under dehydratation or in hemodynamically unstable conditions. Regarding kidney transplantation (KT), the risk of using ACEi/ARBs before surgery is not well established. Therefore, we evaluated the clinical outcomes to determine the effect of preoperative use of ACEi/ARBs on KT. METHODS: We retrospectively collected 1187 patients who received living-donor KT between January 2017 and December 2021...

Insect performance is linked to environmental temperature, and surviving through winter represents a key challenge for temperate, alpine, and polar species. To overwinter, insects have adapted a range of strategies to become truly cold hardy. However, while the mechanisms underlying the ability to avoid or tolerate freezing have been well-studied, little attention has been given to the challenge of maintaining ion homeostasis at frigid temperatures in these species, despite this limiting cold tolerance for insects susceptible to mild chilling...

Pseudohypoaldosteronism type 1 (PHA1) is a rare inherited disorder of resistance to aldosterone and presents with hyponatremia, hyperkalemia, and metabolic acidosis. Cohen syndrome (CS) is another rare inherited disease. Concurrent presentation with pseudohypoaldosteronism makes it so extraordinary and implies more challenges for clinicians. We report a case of a female with Cohen syndrome (novel mutation) and systemic pseudohypoaldosteronism, as well as the challenges we have encountered in the management of this patient...

Dapagliflozin, a sodium-glucose cotransporter 2 inhibitor (SGLT2i), has shown demonstrated benefits for renal and cardiovascular outcomes in large clinical trials. However, short-term concerns regarding its impact on renal function and electrolyte balance exist. This study aimed to evaluate the short-term effects of dapagliflozin on renal function and electrolyte balance in patients newly prescribed the medication. A retrospective analysis of 246 patients who initiated dapagliflozin therapy was conducted. Serum creatinine, sodium, and potassium levels were measured at baseline (before dapagliflozin) and 5-8 days after initiation (endpoint)...
