BACKGROUND/AIMS The aim of this study was to determine whether treatment with β(2)-microglobulin adsorption column (Lixelle) affects bone cysts and clinical symptoms in patients with dialysis-related amyloidosis (DRA). METHODS Radiographic changes in the number and area of bone cysts of the wrist and the hip joint were compared between 39 hemodialysis(More)
Therapeutic plasmapheresis has been used for intractable diseases that cannot be cured by conventional drug therapy. Currently, the use of therapeutic plasmapheresis has been approved for 27 diseases by Japan's National Health Insurance system and is mainly categorized into three modalities: plasma exchange (PE), double-filtration plasmapheresis (DFPP), and(More)
Recent reports have shown that novel phosphate binders containing iron are not only efficacious for the treatment of hyperphosphatemia but also may reduce the need for erythropoiesis-stimulating agents and intravenous (IV) iron for anemia management in patients on maintenance hemodialysis (MHD). Possible healthcare cost savings, which have not been(More)
BACKGROUND/AIMS Mortality in end-stage renal disease patients with dialysis remains high. A high percentage of dialysis patients display signs of chronic microinflammation. To clarify whether microinflammation is involved in the high incidence of poor prognosis in dialysis patients, we investigated the association of inflammatory markers with mortality in a(More)
Multiple sclerosis (MS) in Asian countries, including Japan, is classified into two types: conventional MS (C-MS), characterized mainly by cerebral lesions, and opticospinal MS (OS-MS) or neuromyelitis optica (NMO), characterized by selective involvement of the optic nerve and spinal cord. Recently, a serum immunoglobulin-G-antibody was discovered in(More)
Hepcidin has been established as a central regulator of iron metabolism. In most patients with chronic kidney disease (CKD), serum hepcidin levels are relatively high, favoring iron sequestration in several cell types and organs and thereby leading to iron-related complications. In the absence of overt inflammation, serum hepcidin has been found to be most(More)
In recent times, therapy for renal anemia has changed dramatically in that iron administration has increased and doses of erythropoiesis-stimulating agents (ESAs) have decreased. Here we used a prospective, observational, multicenter design and measured the serum ferritin and hemoglobin levels every 3 months for 2 years in 1086 patients on maintenance(More)
BACKGROUND/AIM Hepcidin could be one of the most important regulators for iron metabolism in patients on maintenance hemodialysis (MHD). The factors affecting serum hepcidin levels were evaluated among indexes of anemia, iron metabolism, or inflammation, as well as the dose of erythropoietin. METHODS 198 MHD patients treated with recombinant human(More)
Both aldosterone and luminal vasopressin may contribute to the maintenance of acid-base homeostasis, but the functional relationship between these hormones is not well understood. The effects of luminal vasopressin likely result from its interaction with V1a receptors on the luminal membranes of intercalated cells in the collecting duct. Here, we found that(More)
The clinical significance of serum ferritin in monitoring the iron status of patients on maintenance hemodialysis (MHD) has become suspected. In this review, we reassess the interpretation of high serum ferritin values in such patients, with the goal of treating their anemia in a safe way. From the observations that (1) H-ferritin gene transcription is(More)
