Efficacy and limitations of additional steroid pulse therapy in IgA nephropathy patients whose hematuria did not remit on tonsillectomy and protocol steroid pulse therapy.

Background: Hematuria is the essential symptom of IgA nephropathy that has been suggested to be associated with long-term renal prognosis, Tonsillectomy and steroid pulse therapy (TSP), which is widely practiced in Japan, is effective for achieving hematuria remission. However, some cases are refractory to TSP, and additional steroid pulse therapy (SP) administered to these cases to achieve remission of hematuria. Nonetheless, the clinical significance of additional SP is unknown.

Changes in Quality of Life in Older Hemodialysis Patients: A Cohort Study on Dialysis Outcomes and Practice Patterns.

Background: Despite improvements in dialysis treatment, mortality rates remain high, especially among older hemodialysis patients. Quality of life (QOL) among hemodialysis patients is strongly associated with higher risk of death. This study aimed to describe the health-related QOL and its change in older maintenance hemodialysis patients and to demonstrate characteristics associated with health-related QOL.

Ruptured renal artery in microscopic polyangiitis: a case report and literature review.

Medium-vessel hemorrhage is a rare occurrence in ANCA-associated vasculitis, and has been previously described in only a few patients with microscopic polyangiitis. We report a case of renal hemorrhage in a patient with microscopic polyangiitis that was successfully managed by transcatheter arterial embolization of the active bleeding sites. The early clinical findings included necrotizing arteritis, as indicated by skin biopsy; rapidly progressive glomerulonephritis; mononeuritis multiplex; positive screening for myeloperoxidase-specific antineutrophil cytoplasmic antibody.

False Elevation of the Blood Tacrolimus Concentration, as Assessed by an Affinity Column-mediated Immunoassay (ACMIA), Led to Acute T Cell-mediated Rejection after Kidney Transplantation.

Tacrolimus is the most commonly used immunosuppressant. Because of its narrow therapeutic range, it is necessary to frequently monitor its concentration. We report the case of a 25-year-old man who underwent kidney transplantation whose tacrolimus concentrations, as measured by an affinity column-mediated immunoassay, were falsely elevated.

Simultaneous nephrotic syndrome and hepatitis in secondary syphilis: case report and review of the literature.

A 66-year-old man presented with a penile ulcer, an acute clinical onset of nephrotic syndrome and hepatitis. Secondary syphilis was diagnosed on the basis of the history of rash and the result of strongly positive serological test for syphilis. A renal biopsy demonstrated membranous glomerulonephritis with subepithelial electron-dense deposits.
