A 28-year-old farmer with class IV lupus nephritis presented with a two-week history of a right shin lesion. The lesion was purple in color, fungating, and indurated with a focus of deep ulceration at the inferior pole and punctate, bleeding from its surface. Three months earlier, he was started on induction immunosuppression for a relapse of his lupus nephritis. Since the diagnosis of lupus nephritis, nine years previously, he had had six flares of his disease and had been treated at different time points with cyclophosphamide, rituximab, and high-dose corticosteroids, without adverse events. Laboratory investigations showed improving kidney function (chronic kidney disease [CKD] stage IV) with reducing proteinuria, on his current immunosuppressive regimen. The differential diagnosis for this lesion was calciphylaxis, pyoderma gangrenosum, vasculitic lesion, or an infection. Histology and microbiological analysis confirmed the presence of Absidia corymbifera. He was treated with a combination of isavuconazole, reduction of his immunosuppressive agents, excision of the lesion, and skin grafting.

Anaemia among haemodialysis patients is treated with iron and erythropoietin-stimulating agents (ESAs). ESAs reduce requirements for blood transfusions but are also expensive and overzealous use may be associated with adverse outcomes. Recent international trends have been characterised by reduced ESA doses and a greater reliance on intravenous (IV) iron. We determined trends in prescribing patterns of ESAs and IV iron for the treatment of anaemia in two representative Irish dialysis centres and correlated with current guidelines and international trends.

Patients with chronic kidney disease (CKD) and ischemic heart disease (IHD) have strikingly high mortality rates. In the general population, there has been a reduction in the mortality and morbidity...
