Pediatr Nephrol
December 2023
Department of Pediatric Nephrology, 2nd Faculty of Medicine, University Hospital Motol, Charles University, Prague, Czech Republic.
Article Synopsis
- Streptococcus pneumoniae-associated hemolytic uremic syndrome (P-HUS) is a rare and serious condition, with limited studies on the use of eculizumab for treatment.
- In this study, data from 7 patients (4 females and 3 males) with pneumonia were analyzed, where 4 received eculizumab, resulting in shorter dialysis and mechanical ventilation times compared to those who did not receive the drug, although still longer than typical durations.
- The use of eculizumab did not significantly improve kidney outcomes over existing reports, and the study found strong correlations between chronic kidney disease (CKD) and the length of dialysis and ventilation support needed.
