Hypokalemia may be present in some patients with Sjogren's syndrome. When a patient syndrome presents hypokalemia, we would first consider it to result of the renal involvement However, this case report, young woman who presented hypokalemia that was not caused by tubular acidosis but presence coexisting aldosterone-producing adenoma. Cases adenoma are extremely rare. This finding underscores n...

normotensive hyperaldosteronism is a rare disorder. it is usually diagnosed with hypokalemia or an adrenal mass. our patient was a 27-year-old female presented with weakness. she had normal blood pressure, hypokalemia, high plasma aldosterone level and suppressed plasma renin activity. after the saline load, test aldosterone didn’t show suppression. adrenal computed tomography revealed a left a...

We examined the effects of acute and/or chronic hypokalemia on responses to 30 min of hypoxia and recovery in the isolated, perfused heart model. We found that both acute hypokalemia and chronic hypokalemia impaired contractility [expressed as maximum slope of pressure increase over time (dP/d t): 501 ± 49 and 529 ± 48 vs. 1,302 ± 118 mmHg/s, P < 0.01] and recovery of ATP concentrations (determ...

Hypokalemia is a common electrolyte disturbance, especially in hospitalized patients. It can have various causes, including endocrine ones. Sometimes, hypokalemia requires urgent medical attention. The aim of this review is to present updated information regarding: (1) the definition and prevalence of hypokalemia, (2) the physiology of potassium homeostasis, (3) the various causes leading to hy...

電解質領域はエビデンスレベルの高い領域ではないため，慣習的に対応しないためにも病態生理の把握は重要である．低カリウム（K）血症に関しては病歴に加え，代謝性アルカローシスの有無，尿電解質の解釈，必要に応じてレニン，アルドステロン等のホルモン検査を行い診断する．治療の原則は原疾患の治療であるが，緊急性のある場合は医原性高K血症に気を付けながらK補充も行う．

BACKGROUND Hyopkalemia is a listed toxicity in the capecitabine (Xeloda(R); Roche, Nutley, NJ) package insert. However, the incidence and severity of this toxicity is not known. METHODS We performed a retrospective evaluation of hypokalemia in 77 patients, who received capecitabine for gastrointestinal malignancies between April 2002 and November 2004. Hypokalemia was defined as K(+) level <3...

BACKGROUND Severe hypokalemia is known to cause muscle paralysis, and renal tubular acidosis is a recognized cause. Cystic disease of the kidney is associated with severe hypokalemia. CASE PRESENTATION We report a 33-year-old male patient who presented with generalized limb weakness caused by severe hypokalemia due to renal tubular acidosis, who was found to have renal medullary cysts. CONC...

Hypokalemia is a common electrolyte abnormality. Generally being asymptomatic, muscular fatigue, paresis and arrhythmia can be seen as the severity of hypokalemia increases. Severe rhabdomyolysis neuromuscular findings in severe cases. Presence precursor secondary hypertension hypertensive patients, also should bring hyperaldosteronism into consideration. Mild usually primary hyperaldosteronism...

Hypokalemia is a frequent problem in patients on continuous ambulatory peritoneal dialysis (CAPD) and is affected by multiple factors. To evaluate factors associated with hypokalemia, we studied 68 patients on maintenance CAPD treatment for at least six months. In univariate analysis, patients with hypokalemia were associated with older age and the presence of diabetes mellitus. Serum albumin, ...
