Severe Yellow Fever and Extreme Hyperferritinemia Managed with Therapeutic Plasma Exchange.

A 43-year-old man was admitted to the intensive care unit and diagnosed with yellow fever. He presented with refractory bleeding, extreme hyperferritinemia, and multiple organ dysfunction syndrome, requiring renal replacement therapy, mechanical ventilation, and treatment with vasoactive drugs. Because the bleeding did not respond to fresh-frozen plasma administration, the patient received therapeutic plasma exchange, which was accompanied by a marked improvement of the clinical and biochemical parameters, including a significant decline in serum ferritin levels.

Evolution Over Time of Volume Status and PD-Related Practice Patterns in an Incident Peritoneal Dialysis Cohort.

Background And Objectives: Volume overload is frequent in prevalent patients on kidney replacement therapies and is associated with outcome. This study was devised to follow-up volume status of an incident population on peritoneal dialysis (PD) and to relate this to patient-relevant outcomes.

Design, Setting, Participants, & Measurements: This prospective cohort study was implemented in 135 study centers from 28 countries.
