Kayexalate is an ion exchange resin that is commonly used to acutely treat patients with hyperkalemia. Bowel ulceration and necrosis is a rare and uncommonly recognized complication of kayexalate administration. More often, concomitant administration with sorbitol is reported to damage the bowel; however, there are reports of kayexalate administration causing bowel necrosis without sorbitol. We present a case of a critically ill patient who underwent total colectomy for colonic necrosis secondary to oral kayexalate administration that was not recognized until late in the pathologic process...

BACKGROUND: Choice of the optimal target for blood pressure (BP) reduction during treatment of patients with hypertension, including those with underlying co-morbid conditions, is an important challenge in clinical practice. The Systolic Blood Pressure Intervention Trial (SPRINT) was designed to provide guidance in selection of a Systolic BP target during treatment of hypertension. METHODS: Adults ≥50 years old with hypertension and at least one additional risk factor for cardiovascular disease (CVD), but excluding persons with diabetes mellitus, prior stroke, or advanced chronic kidney disease (CKD) were randomly assigned to intensive therapy (intensive), targeting a systolic BP (SBP) <120 mmHg, or standard therapy (standard), targeting a SBP <140 mmHg...

OBJECTIVE: Diuretics, alone or in combination, are frequently prescribed in chronic kidney disease (CKD) and heart failure (HF) patients to reduce volume, blood pressure, and/or for symptom control. Clinicians may also use them to reduce the risk of hyperkalemia, but high doses of diuretics may lead to adverse events from intravascular volume depletion or gout. Patiromer is a non-absorbed K-binding polymer recently approved by the FDA for the treatment of hyperkalemia (HK). We compared patiromer's effects in RAASi-treated CKD patients with HK on different types of diuretics to patients not receiving diuretics in the treatment phase of OPAL-HK...

OBJECTIVE: Elevated serum aldosterone can be vasculotoxic and facilitates cardiorenal damage. Renin-angiotensin-aldosterone inhibitors (RAASi) reduce serum aldosterone levels and/or block its effects but can cause hyperkalemia (HK). Patiromer, a nonabsorbed potassium binder, decreases serum potassium (K) in CKD patients on RAASi. We examined the effect of patiromer on serum aldosterone levels, plasma renin activity (PRA), systolic (SBP) and diastolic blood pressure (DBP), and urinary albumin-to-creatinine ratio (UACR) in CKD patients on RAASi with HK (serum K 5...

BACKGROUND: Cardiac resynchronization therapy (CRT) is a medical device to help cardiac synchronized contractility by electrical impulses. Improvement of symptoms and left ventricular systolic function, reducing hospital admissions and mortality in patients with moderate to severe heart failure are the main benefits of administration of cardiac resynchronization therapy. CASE REPORT: In this article, we describe a case of heart failure and left bundle branch block (LBBB) who was candidate for cardiac resynchronization therapy; but after managing hyperkalemia, left bundle branch block resolved, ejection fraction increased and cardiac resynchronization therapy implantation was canceled...

Hump-nosed viper (Hypnale hypnale; HNV) is one of the six major snake species in Sri Lanka that cause envenomation. Nephrotoxicity, coagulopathy, and neurotoxicity are wellrecognized features of its envenomation. Type 4 renal tubular acidosis (RTA4) has only once been described previously in this condition, and we report two further cases. Two patients aged 53 and 51 presented following HNV bites with acute kidney injury and microangiopathic hemolytic anemia. Both underwent multiple cycles of hemodialysis until the polyuric phase was reached...

A 54-year-old woman presented at the emergency department after experiencing lower limb weakness and bilateral ankle pain for 2 days. She had a history of type 2 diabetes mellitus, diabetes mellitus nephropathy with chronic kidney disease, and chronic gouty arthritis. She had received 0.6 mg colchicine orally once or twice daily for 8 months. Four days prior to her emergency department visit, she was discharged from our nephrology ward, where she had been admitted because of a urinary tract infection. During hospitalization, she was treated with intravenous cefazolin for 7 days...

BACKGROUND: Vaptans, vasopressin selective V2-receptor antagonist, represent the first pharmacological approach to the treatment of hypervolemic hyponatremia in cirrhosis. However, information on the use of vaptans for patients with cirrhosis and hyponatremia in a real-life scenario is very limited. Therefore, this study evaluated the effect of tolvaptan on serum sodium in patients with cirrhosis and severe hypervolemic hyponatremia. METHODS: Nine patients with cirrhosis and serum sodium <125mEq/L were included...

Potassium levels are often abnormal in patients with heart failure (HF) and have a detrimental effect on clinical outcome. We evaluated potassium levels in a real-world cohort of patients with HF and its effect on mortality. All patients with a diagnosis of HF at a health maintenance organization were evaluated and followed for cardiac-related hospitalizations and death. The cohort consisted of 6,073 patients with HF. Mean potassium levels were 4.57 ± 0.53 mmol/L. Most patients (68%) had potassium levels in the normal range (4...

Hyperkalemia is a common electrolyte disorder associated with life-threatening cardiac arrhythmias and increased mortality. Patients at greatest risk for hyperkalemia include those with diabetes and those with impaired renal function in whom a defect in the excretion of renal potassium may already exist. Hyperkalemia is likely to become more common clinically because angiotensin receptor blockers and angiotensin-converting enzyme inhibitors are increasingly being used in higher doses and are thought to confer cardiovascular and renal protection...

BACKGROUND: A multidrug treatment strategy that targets urinary proteins with an angiotensin-converting enzyme (ACE) inhibitor and angiotensin receptor blocker (ARB) up-titrated to the respective maximum tolerated dose combined with intensified blood pressure (BP) control has been found to prevent renal function loss in adults with proteinuric nephropathies. Herein, we investigated the effects of this treatment protocol in the pediatric patient population. METHODS: From May 2002 to September 2014 we included in this observational, longitudinal, cohort study 20 consecutive children with chronic nephropathies and 24-h proteinuria of >200 mg who had received ramipril and losartan up-titrated to the respective maximum approved and tolerated doses [mean (standard deviation) dose:2...

Hyperkalemia is a common electrolyte disorder, especially in chronic kidney disease, diabetes mellitus, or heart failure. Hyperkalemia can lead to potentially fatal cardiac dysrhythmias, and it is associated with increased mortality. Determining whether emergency therapy is warranted is largely based on subjective clinical judgment. The Investigator Network Initiative Cardiovascular and Renal Clinical Trialists (INI-CRCT) aimed to evaluate the current knowledge pertaining to the emergency treatment of hyperkalemia...

An adult, intact male sugar glider ( Petaurus breviceps ) presented for acute caudal abdominal swelling. Treatment by the referring veterinarian included aspiration of urine from the swelling. On physical examination, mild depression, pale mucus membranes, and caudal abdominal swelling were noted. Focused ultrasonographic assessment revealed a fluid-filled caudal abdominal structure and subjective bladder wall thickening. The following day, the sugar glider was severely depressed. Hematology results included hypoglycemia, hyperkalemia, hyponatremia, and azotemia...

Disorders of potassium homeostasis can potentiate the already elevated risk of arrhythmia in heart failure. Heart failure patients have a high prevalence of chronic kidney disease, which further heightens the risk of hyperkalemia, especially when renin-angiotensin-aldosterone system inhibitors are used. Acute treatment for hyperkalemia may not be tolerated in the long term. Recent data for patiromer and sodium zirconium cyclosilicate, used to treat and prevent high serum potassium levels on a more chronic basis, have sparked interest in the treatment of hyperkalemia, as well as the potential use of renin-angiotensin-aldosterone system inhibitors in patients who were previously unable to take these drugs or tolerated only low doses...
