Membranous glomerulonephropathy in a patient with bullous pemphigoid.

Bullous pemphigoid (BP) is a common autoimmune blistering disease that can be complicated by autoimmune disorders. We describe a patient with BP who developed membranous glomerulonephropathy (MN). Proteinuria decreased during the clinical course as anti-BP180 antibody titers decreased.

Associations among Erythroferrone and Biomarkers of Erythropoiesis and Iron Metabolism, and Treatment with Long-Term Erythropoiesis-Stimulating Agents in Patients on Hemodialysis.

Background: We aimed to identify associations between erythroferrone (ERFE), a regulator of hepcidin 25, and biomarkers of erythropoiesis and iron metabolism. We also aimed to determine the effects of erythropoiesis-stimulating agents (ESA), continuous erythropoietin receptor activator (CERA) and darbepoetin-α (DA) on ERFE production in patients on hemodialysis (HD).

Methods: Blood samples were obtained from 59 patients before HD sessions on day 0 (baseline).

Effects of Long-Term Erythropoiesis-Stimulating Agents on Iron Metabolism in Patients on Hemodialysis.

Continuous erythropoietin receptor activator (CERA) and darbepoetin-α (DA) might differently affect iron metabolism and erythropoiesis in patients on hemodialysis (HD). This prospective study examined a cohort of patients on HD who had received either intravenous CERA every 2 or 4 weeks (N = 25) or DA once each week (N = 47). Blood was sampled before HD sessions on days 0, 2, 4, 7 and 14, and on days 0, 3, 5, 7 and 14 from patients who were injected with ESA at the beginning and end of the dialysis week, respectively.
