Suppression of parathyroid hormone secretion in CAPD patients by intraperitoneal administration of Maxacalcitol.

Background: Maxacalcitol (22-oxacalcitriol; OCT) is a novel vitamin D analogue. In previous clinical studies, OCT was administered three times a week to hemodialysis patients with refractory secondary hyperparathyroidism (2HPT), in whom it acted by inhibiting parathyroid hormone secretion, as well as causing mildly elevated serum calcium. However, intravenous injection of OCT, which requires frequent visits to the outpatient clinic, degrades the quality of life of patients with continuous ambulatory peritoneal dialysis (CAPD) who otherwise visit the clinic only once or twice per month.

Efficacy of granulocytapheresis and leukocytapheresis for the treatment of microscopic polyangiitis.

We evaluated the efficacy of granulocytaperesis and leukocytapheresis for the treatment of rapidly progressive glomerulonephritis (RPGN) and lung hemorrhage caused by microscopic polyangiitis. Three patients with RPGN were treated by granulocytapheresis (GCAP) and five patients with RPGN were treated by leukocytapheresis (LCAP). The prednisolone dose was 0.

Cytapheresis for the treatment of myeloperoxidase antineutrophil cytoplasmic antibody-associated vasculitis: report of five cases.

To minimize the adverse effects of high-dose administration of steroids and cyclophosphamide in patients with myeloperoxidase (MPO) antineutrophil cytoplasmic antibody (ANCA), granulocytapheresis (GCAP) or leukocytapheresis (LCAP) was performed to reduce inflammation. Four patients with rapidly progressive glomerulonephritis (RPGN) and one patient with pulmonary hemorrhage due to MPO-ANCA-associated vasculitis were treated by cytapheresis. The prednisolone (PSL) dose was 0.

[Evaluation of reticulocyte hemoglobin content, percentage of hypochromic red blood cells, and ratio of serum transferrin receptor level/serum iron level as markers of iron-deficiency erythropoiesis in patients undergoing hemodialysis].

Unlabelled: Reticulocyte hemoglobin content(CHr), percentage of hypochromic red blood cells(%HRC, level of serum transferrin receptor(sTfR), and sTfR/serum iron ratio(sTfR/Fe) were measured in 132 hemodialysis patients. On univariate analysis, CHr was positively correlated with serum amyloid A(SAA) and negatively correlated with Kt/V. %HRC showed a positive correlation with the recombinant human erythropoietin(rHuEPO) dosage.
