We report here a 79-year-old male having sarcoidosis without presentation of typical findings, such as respiratory symptoms, ocular signs, or skin lesions. Two weeks prior to admission to our hospital, he presented to a different hospital with acute renal failure, with blood urea nitrogen (BUN) and serum creatinine (Cr) levels of 67.9 mg/dl and 7.97 mg/dl,(More)
BACKGROUND It is difficult to diagnose tuberculosis (TB) in dialysis patients because of the high rate of extrapulmonary TB in these patients compared with the general population. Recently, a new diagnostic test called QuantiFERON (QFT) has been developed and shown promise as a diagnostic tool for active TB diseases and latent TB infection. METHODS We(More)
The incidence of cholesterol crystal embolism (CCE) has increased along with increases in the prevalence of atheromatous diseases and intravascular procedures. CCE frequently results in the deterioration of renal function, which sometimes leads to end-stage renal failure. Although there has been no established therapy for CCE, the possibility that(More)
Type 2 diabetic kidney disease (DKD) is frequently accompanied by uncontrollable hypertension due to the sodium sensitivity inherent in DKD and to diuretic-resistant edema. In general, diuretics are effective in treating this condition, but thiazide diuretics are thought to be innocuous in advanced chronic kidney disease (CKD). We examined the(More)
BACKGROUND/AIMS Patients undergoing hemodialysis (HD) have higher occurrence rates of cerebral diseases, including uremic encephalopathy, cognitive impairment, dementia, and cerebrovascular disease, than the general population. During HD, ultrafiltration is performed to maintain an adequate fluid condition and is associated with subsequent blood volume (BV)(More)
BACKGROUND Patients undergoing hemodialysis (HD) often develop cerebral disease complications. Furthermore, cerebral regional saturation of oxygen (rSO2) was previously reported to be significantly lower in HD patients than in healthy subjects. We aimed to identify the factors affecting the cerebral rSO2 in HD patients. METHODS Fifty-four HD patients (38(More)
BACKGROUND The presence of renal failure in patients with multiple myeloma (MM) has been considered an ominous prognostic factor associated with a significantly decreased life expectancy. The prognostic factors have seldom been analyzed to predict discontinuation of hemodialysis (HD) therapy in MM patients with renal failure after HD initiation. It is(More)
BACKGROUND Hyperkalemia is one of the more serious complications of chronic kidney disease (CKD), and the cause of potassium retention is a reduction in urinary potassium excretion. However, few studies have examined the extent of the decrease of urinary potassium excretion in detail with respect to decreased renal function. METHODS Nine hundred(More)
An elderly patient with pure red cell aplasia (PRCA) with antierythropoietin (anti-EPO) antibodies is described. PRCA due to alloimmunization is a rare and severe complication of recombinant human erythropoietin (rHu-EPO) therapy. Most reported patients with PRCA were cured primarily by immunosuppressive drug therapy. The patient in this case, however, did(More)
AIM To evaluate the lower-limb muscle oxygenation in hemodialysis (HD) patients and identify the factors associating with muscle oxygenation. METHODS Sixty-seven HD patients (53 men and 14 women; mean age, 67.1 ± 1.2 years; mean HD duration, 5.6 ± 0.9 years) were recruited. In addition, 15 healthy individuals (nine men and six women; mean age, 38.2 ± 4.6(More)
