refractory hyperkalemia

Adrenal insufficiency (AI) is one of the most life-threatening disorders resulting from adrenal cortex dysfunction. Symptoms and signs of AI are often nonspecific, and the diagnosis can be missed and lead to the development of AI with severe hypotension and hypovolemic shock. We report the case of a 13-year-old child admitted for cardiac arrest following severe hypovolemic shock. The patient initially presented with isolated mild abdominal pain and vomiting together with unexplained hyponatremia. He was discharged after an initial short hospitalization with rehydration but with persistent hyponatremia...

Effects of angiotensin receptor/neprilysin inhibitors (ARNI) on ventricular remodeling in patients with heart failure, especially heart failure with reduced ejection fraction (HFrEF), are better than those of angiotensin-converting enzyme inhibitors (ACEI). Acute myocardial infarction (AMI) complicated by mitral regurgitation exacerbates ventricular remodeling and increases the risk of heart failure. There is limited evidence on the effects of early administration of ARNI in patients with AMI complicated by mitral regurgitation...

Management of diabetic ketoacidosis (DKA) has internationally established guidelines. However, management of severe, refractory DKA with multiple contributors to acidosis, and management of DKA in patients with altered mentation, remain ambiguous. Use of sodium bicarbonate and intubation in DKA are unpopular treatment practices, but warrant consideration in these unique clinical scenarios. This paper describes a 61-year-old Sri Lankan female who presented with severe DKA, seizures and altered level of consciousness...

Trimethoprim-sulfamethoxazole (TMP-SMX) is the primary therapeutic option for Pneumocystis jirovecii pneumonia (PCP). Gastrointestinal symptoms and cutaneous rash are common side effects, with hyperkalemia being uncommon in patients without kidney dysfunction, and myelotoxicity being even rarer. We present the case of a male patient with hypertension and a recent diagnosis of non-Hodgkin lymphoma, undergoing rituximab treatment for two months. He was admitted to the intensive care unit due to dyspnea, tachypnea, and pleuritic pain, requiring mechanical ventilation...

BACKGROUND: Erythropoiesis-stimulating agents (ESAs) have played an important role in the treatment of renal anemia in children, but cannot improve hemoglobin to target level in some cases. Roxadustat, a hypoxia-inducible factor prolyl hydroxylase inhibitor, can stimulate endogenous erythropoietin production and regulate iron metabolism even in patients with kidney failure. However, roxadustat has not yet been approved for use in children. CASE-DIAGNOSIS/TREATMENT: We report a case of refractory renal anemia in an 80-day-old boy, who was hyporesponsive to ESAs even in combination with iron supplementation and transfusion...

INTRODUCTION: Refractory status epilepticus (RSE) is a diagnosis that can be made when tonic-clonic status epilepticus (SE) and focal SE cannot be stopped by at least two anti-seizure medications after 30 and 60 minutes, respectively, from the time of commencement. It could result in mortality, loss of functionality, neurological deficiency, and other serious short- and long-term effects. AREAS COVERED: This narrative review covers original clinical studies of any design and case series investigating long-term outcomes of RSE recorded after at least a year from the SE onset...

BACKGROUND: Patients with bilateral primary aldosteronism (PA) generally are treated with antihypertensive drugs, but optimal treatment for patients with complications due to refractory hypertension has not been established. In this report, we present a case with bilateral PA who presented with persistent hypertension, despite treatment with 6 drugs, and left-dominant heart failure, which was improved after unilateral adrenalectomy. CASE PRESENTATION: A 61-year-old man was admitted to our hospital because of severe left-dominant heart failure...

Hyperkalemia refractory to standard temporization measures can be life-threatening, and urgent hemodialysis is often utilized as a final resort. Our patient presented with hyperkalemia that was multifactorial in etiology, with acute kidney injury complicated by adrenal insufficiency. Her hyperkalemia was refractory to temporization and excretion agents, and hemodialysis was being considered. Given a recent infection, surgery, and borderline hypotension with low adrenocorticotropic hormone, there was a concern for adrenal insufficiency...

We present a case involving an 87-year-old woman who had a hyperkalemic emergency. This condition was further complicated by complete heart block (CHB) and seizure-like activity. This case emphasizes the challenge of differentiating between seizures and convulsive syncope. Achieving an accurate diagnosis is essential for determining the appropriate medical treatment. This case report highlights the various symptoms and complications associated with hyperkalemia, emphasizing the importance of conducting a thorough examination to explore other potential causes...

The BRASH syndrome is an uncommon but serious medical condition that is distinguished by a confluence of symptoms that include bradycardia, renal failure, AV node dysfunction, shock, and hyperkalemia. Bradycardia associated with BRASH syndrome is often refractory to conventional management guided by advanced cardiac life support (ACLS), therefore prompt and appropriate intervention can only be administered in the setting of early recognition. The management of BRASH syndrome in elderly patients can prove to be particularly challenging, primarily because of pre-existing comorbidities that place these patients at increased risk of complications...

UNLABELLED: The clinical spectrum of leptospirosis ranges from subclinical infection and anicteric fever to Weil's disease, a severely fatal infection. Acute inflammation of the pancreas is a rare manifestation of Weil's disease, and renal involvement is a hallmark in severe forms, leading to acute kidney injury (AKI) and representing a major risk factor for death. The aim of the case report was to present the clinical manifestations of Weil's disease with acute pancreatitis and AKI and to highlight the management of its complications...

A 75-year-old man was admitted with a diagnosis of diabetic ketoacidosis and hyperkalemia. During the treatment, he developed refractory hyperkalemia. Following our review, diagnosis of pseudohyperkalaemia secondary to thrombocytosis was made. We report this case to remind the importance of clinical suspicion of this phenomenon to prevent its serious consequences.

Chronic kidney diseases (CKD) and cardiovascular diseases (CVD) are the main complications in type 2 diabetic mellitus (T2DM), increasing the risk of cardiovascular and all-cause mortality. Current therapeutic strategies that delay the progression of CKD and the development of CVD include angiotensin-converting enzyme inhibitors (ACEI), angiotensin II receptor blockers (ARB), sodium-glucose co-transporter 2 inhibitors (SGLT-2i) and GLP-1 receptor agonists (GLP-1RA). In the progression of CKD and CVD, mineralocorticoid receptor (MR) overactivation leads to inflammation and fibrosis in the heart, kidney and vascular system, making mineralocorticoid receptor antagonists (MRAs) as a promising therapeutic option in T2DM with CKD and CVD...

Mineralocorticoid deficiency (MD) with hyperkalemia is an important complication of adrenalectomy in patients with primary aldosteronism (PA). We herein report a 52-year-old man with refractory hypertension, hypokalemia, and severe renal dysfunction due to PA caused by a right adrenal adenoma. His estimated glomerular filtration rate (eGFR) transiently increased immediately after adrenalectomy but then gradually declined, and he developed hyperkalemia. A postoperative endocrine examination revealed MD. Considering the patient's hypertension and severe renal dysfunction, we administered hydrocortisone instead of fludrocortisone, which improved the hyperkalemia and stopped the decline in the eGFR...

A 76-year-old man was evaluated in our emergency department (ED) for right toe swelling and pain. His initial ED workup revealed volume overload, uncontrolled hypertension, slow atrial fibrillation, refractory hypokalemia, mixed metabolic alkalosis and respiratory acidosis, with a normal plasma pH, and hypernatremia. His medical chart revealed long standing hyperkalemia and metabolic acidosis, related to his diabetic kidney disease. We hypothesized that a short course of daily SPS ingestion (Sodium Polystyrene Sulfonate, "Kayexalate") was the sole etiology for the compound electrolyte abnormalities and the electrolyte "flip flop"...

Nicorandil is an anti-anginal drug that is commonly used in the treatment of ischemic heart disease. Nicorandil acts as a nitrate donor and ATP-sensitive potassium channel agonist, inducing coronary artery vasodilation. Potassium efflux through ATP-sensitive potassium channels activated by nicorandil can cause refractory hyperkalemia, particularly in patients with chronic kidney disease (CKD). Here, we report the case of an 85-year-old man who presented with severe refractory hyperkalemia, despite proper medical management...

BACKGROUND: Persistent hyperkalemia (hyperK) and hyperphosphatemia (hyperP) despite renal replacement therapy (RRT) was anecdotally reported in COVID-19 and acute kidney injury (AKI) requiring RRT (CoV-AKI-RRT). However, observation bias could have accounted for the reports. Thus, we systematically examined the rate and severity of hyperK and hyperP in patients with CoV-AKI-RRT in comparison with the pre-COVID-19 era. METHODS: We identified patients with CoV-AKI-RRT treated with sustained low-efficiency dialysis (SLED) for ≥2 days in March-April 2020...

Background: Mortality of patients who are critically ill with AKI initiated on RRT is very high. Identifying modifiable and unmodifiable clinical variables at dialysis start that are associated with hospital survival can help, not only in prognostication, but also in clinical triaging. Methods: A retrospective observational study was conducted on patients with AKI-D who were initiated on RRT in the medical and surgical intensive care units (ICUs) of a high-acuity academic medical center from January 2010 through December 2015...

Potassium binders are essential tools to treat hyperkalemia, particularly in patients with heart failure and chronic kidney disease. One of the drug-related complications is constipation, which further worsens heart failure by increasing afterload and decreases patients' quality of life. We encountered an 82-year-old man with heart failure, chronic kidney disease, and hyperkalemia. A conventional potassium binder, calcium polystyrene sulfonate, ameliorated his hyperkalemia, whereas he became aware of refractory constipation...

INTRODUCTION: Each dialysis session uses approximately 150 to 200 L of water. The winter storm that swept southwest USA saw an unprecedented disruption of water supplies due to which intermittent hemodialysis could not be performed for end-stage renal disease (ESRD) patients. We present 4 cases when continuous renal replacement therapy (CRRT) was utilized to provide urgent hemodialysis in hemodynamically stable, non-critically ill ESRD patients during this time of water supply crisis...
