Renal involvement in COVID-19 infection is varied and worsens its outcome and prognosis. However, the association of COVID-19 infection with glomerulonephritis is exceptional. We report a 46-year-old woman with COVID-19 who had an acute kidney injury and ANCA associated glomerulonephritis two weeks after the onset of the disease. The kidney biopsy showed a crescentic glomerulo-nephritis and the presence of anti-glomerular basement membrane antibodies (GBM-Abs). She was treated with steroids and oral cyclophosphamide with good response without requiring plasmapheresis. Plasma anti GBM-Abs were negative. This case suggests that the presence of anti-GBM-Abs in the kidney, was temporally related to COVID-19 pulmonary damage. The absence of plasma antibodies is probably due to transient production and glomerular adsorption, but with unknown pathogenic role.

Fungal peritonitis is a major complication of peritoneal dialysis associated with high mortality. Most survivors have a high rate of abandonment of peritoneal dialysis. We report a case of fungal peritonitis due to an unusual agent. An 83 year-old woman, with a history of type 2 diabetes mellitus and multiple episodes of bacterial peritonitis associated to technical flaws in the implementation of automated peritoneal dialysis, was admitted due to abdominal pain and cloudy peritoneal fluid. Rhodotorula mucilaginosa was identified in the peritoneal fluid by MALDI-TOF. She was treated with catheter removal and oral posaconazole for 14 days showing clinical resolution and non-recurrence.

La peritonitis fúngica es una complicación mayor de la diálisis peritoneal, con una alta mortalidad asociada y la mayoría de los sobrevivientes presentan una alta tasa de abandono de diálisis peritoneal como terapia de reemplazo renal. Se presenta un caso de peritonitis fúngica por un agente infrecuente. Mujer de 83 años, diabética con múltiples episodios de peritonitis bacteriana asociada a fallas técnicas en la ejecución de diálisis peritoneal automatizada, ingresa por cuadro clínico de dolor abdominal y líquido peritoneal turbio. Se confirmó la presencia de Rhodotorula mucilaginosa en líquido peritoneal mediante MALDI-TOF. Fue tratada con retiro del catéter y posaconazol oral por 14 días, presentando una evolución favorable.
