BACKGROUND: Extracellular metabolic acidosis of mineral origin is commonly associated with plasma hyperkalemia. Nevertheless, in previous experiments, animals subjected to acute metabolic acidosis induced by normovolemic hemodilution using a colloidal volume replacement solution containing succinylated gelatin (gelafundin), developed a hypokalemic state with concomitant marked increases in diuresis and renal potassium excretion. In the present study, the succinylated gelatin's impact on diuresis and consequently potassium excretion was studied...

Hypokalemia is more common than hyperkalemia and usually is caused by excessive losses of potassium from the kidneys or gastrointestinal tract. Serum potassium should be investigated in patients developing chronic or frequent vomiting or diarrhea, marked polyuria, muscle weakness, or unexpected cardiac arrhythmias, as well as in those undergoing therapy with insulin, diuretics, or total parenteral nutrition. Clinical signs develop when serum potassium deficit is moderate or severe.

REVIEW
Márcia Mery Kogika, Helio Autran de Morais
The clinical signs of hyperkalemia usually are less evident than hypokalemia. Arrhythmia and bradycardia could be the first changes noticed. Most cases of persistent hyperkalemia are associated with renal retention of potassium. Common causes for hyperkalemia include hypoadrenocorticism, ruptured bladder, and urethral or bilateral ureteral obstruction. Drug such as angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, potassium-sparing diuretics, and nonsteroidal antiinflammatory drugs can also lead to hyperkalemia...

Hypokalemia and hyperkalemia are the most common electrolyte disorders managed in the emergency department. The diagnosis of these potentially life-threatening disorders is challenging due to the often vague symptomatology a patient may express, and treatment options may be based upon very little data due to the time it may take for laboratory values to return. This review examines the most current evidence with regard to the pathophysiology, diagnosis, and management of potassium disorders. In this review, classic paradigms, such as the use of sodium polystyrene and the routine measurement of serum magnesium, are tested, and an algorithm for the treatment of potassium disorders is discussed...

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...

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...

BACKGROUND: As the field of Primary Aldosteronism (PA) becomes ever expanded, diagnosis of PA is increasingly diagnosed by endocrinologists. With increased PA screening, many of the cases are now found in patients with complex co-morbidities in addition to their hypertension. Post adrenalectomy renal impairment with hyperkalemia is now increasingly seen in these complex patients, as evidenced by the numerous reports on this issue that have appeared within the past 3 years. We present a small case series to illustrate the breadth of the problem, along with a discussion about how such CKD/hyperkalemic events may be predicted...
