Is it possible to predict persistent acute kidney injury in critically ill patients with COVID-19 infection?

Introduction: Critically ill patients with coronavirus disease 2019 (COVID-19) often face a heightened risk of morbidity and mortality, particularly due to complications such as acute kidney injury (AKI). While the persistent acute kidney injury risk index (PARI) has shown promise in predicting the risk of persistent AKI (pAKI) in non-COVID patients, its effectiveness in critically ill COVID-19 patients remains to be explored. We aimed to evaluate the predictive power of the PARI in identifying pAKI and its prognostic significance in terms of clinical outcomes.

Neopterin, homocysteine, and ADMA levels during and after urticaria attack.

Background/aim: Urticaria is a vascular skin reaction characterized with papules and plaques. Neopterin is accepted as an immunologic marker and an indicator of activation of the immune system. Homocysteine and asymmetric dimethylarginine (ADMA) are the markers of increased vascular resistance.
