Atypical Hemolytic Uremic Syndrome Occurring After Receipt of mRNA-1273 COVID-19 Vaccine Booster: A Case Report.

Atypical hemolytic uremic syndrome (aHUS) is a subtype of thrombotic microangiopathy (TMA) characterized by a dysregulation of the alternative complement pathway. Here, we report a previously healthy 38-year-old woman in whom aHUS developed after a COVID-19 vaccine booster. One day after receipt of a booster dose of mRNA-1273 vaccine, she felt ill.

Frailty and Mortality in Hospitalized Older Adults With COVID-19: Retrospective Observational Study.

Objectives: To determine the association between frailty and short-term mortality in older adults hospitalized for coronavirus disease 2019 (COVID-19).

Design: Retrospective single-center observational study.

Setting And Participants: Eighty-one patients with COVID-19 confirmed by reverse-transcriptase polymerase chain reaction (RT-PCR), at the Geriatrics department of a general hospital in Belgium.

OPAT: proof of concept in a peripheral Belgian hospital after review of the literature.

Since its introduction in the 1970s in the United States, outpatient parenteral antibiotic/antimicrobial therapy (OPAT) has been adopted internationally for long-term intravenous (IV) treatment of stable infectious diseases. The aim is to provide a safe and successful completion of IV antimicrobial treatment at the ambulatory care center or at home without complications and costs associated with hospitalization. OPAT implementation has been accelerated by progress in vascular access devices, newly available antibiotics, the emphasis on cost-savings, as well as an improved patient comfort and a reduced incidence of health care associated infections with a similar outcome.

The ABC of pneumococcal infections and vaccination in patients with chronic kidney disease.

Background: In the general population, pneumococcal polysaccharide vaccines (PPV) decrease the incidence of invasive pneumococcal disease (IPD) whereas the impact on the prevention of noninvasive pneumococcal disease is less clear. As compared with PPV, pneumococcal conjugate vaccines (PCV) provoke a higher, longer-lasting immune response resulting in a 45% decreased incidence in vaccine-type pneumonia, and a 75% decrease in vaccine-type IPD.

Methods: Literature review on pneumococcal vaccination in end-stage renal disease.
