BACKGROUND The clinical use of cisplatin (cis-diamminedichloro-platinum II, CDDP) is highly limited by its nephrotoxicity. Although N-acetylcysteine (NAC), a thiol-containing antioxidant, has been documented to be effective in attenuating renal injury induced by CDDP, the precise mechanisms involved in its renoprotection have not been completely clarified.(More)
BACKGROUND Chronic kidney disease (CKD) is a risk factor for end-stage renal failure and cardiovascular disease, and a strategy to counteract CKD must be established. CKD caused by immunological abnormalities is treated by steroids, frequently resulting in steroid diabetes. Although insulin is the most effective drug against steroid diabetes, administering(More)
Membranous nephropathy (MN) is a leading cause of nephrotic syndrome in adults. Autoantibodies against M-type phospholipase A2 receptor (PLA2R) and thrombospondin type-1 domain-containing 7A (THSD7A), which mainly belong to the IgG4 subclass, were reported as associated antibodies for the development of MN. Although PLA2R is a major target antigen for(More)
BACKGROUND/AIMS Systemic inflammation-based prognostic scores have prognostic power in patients with cancer, independently of tumor stage and site. Although inflammatory status is associated with mortality in hemodialysis (HD) patients, it remains to be determined as to whether these composite scores are useful in predicting clinical outcomes. METHODS We(More)
BACKGROUND Establishment of non-invasive urinary biomarkers for the prediction of acute renal failure (ARF) is important. We evaluated whether urinary oxidative stress markers reflect intrarenal oxidative stress in cisplatin (CDDP)-induced ARF, and whether these markers can be used for the prediction of future ARF. METHODS Urinary malondialdehyde (MDA)(More)
BACKGROUND High body mass index (BMI) is paradoxically associated with better outcomes in hemodialysis (HD) patients. This study aimed to examine whether serum creatinine (Cr), a marker of muscle mass, could modify the association between BMI, and mortality and morbidity in prevalent HD patients. METHODS A retrospective study was conducted using a(More)
BACKGROUND Acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) has an extremely poor prognosis and there is currently no effective treatment for this condition. Direct hemoperfusion with a polymyxin B-immobilized fiber column (PMX-DHP) improves oxygenation, but it is unclear whether treatment of AE-IPF with PMX-DHP affects survival. This study(More)
Chronic kidney disease (CKD) is a risk factor for end-stage renal failure and cardiovascular events. In patients with CKD, anemia is often caused by decreased erythropoietin production relative to hemoglobin levels. As correction of anemia is associated with improved cardiac and renal function and quality of life, erythropoiesis-stimulating agents (ESAs)(More)
Objective Hypertension and diurnal blood pressure (BP) variation are widely accepted as risk factors for renal damage. However, the effects of unilateral nephrectomy on BP and its circadian rhythm have not yet been clarified in patients with a compromised renal function, including dialysis patients. Methods We investigated 22 unilateral nephrectomized(More)
AIM To investigate the relationship between plasma ghrelin level, Helicobacter pylori (H. pylori) infection status and the severity of atrophy in hemodialysis patients. METHODS One hundred eights patients who received hemodialysis and 13 non-hemodialysis H. pylori-negative controls underwent gastroduodenoscopy to evaluate the severity of gastric atrophy.(More)
