Abstract

This work comments on an article published in the recent issue of the World Journal of Virology. Rhabdomyolysis is a complex condition with symptoms such as myalgia, changes to urination, and weakness. With the potential for substantial kidney impairment, it has also been shown to be a severe complication of coronavirus disease 2019 (COVID-19). To date, various theoretical explanations exist for the development of rhabdomyolysis induced acute kidney injury (RIAKI) in COVID-19 infection, including the accumulation of released striated muscle myoglobin in the urine (myoglobinuria). In their article, they (2024) demonstrate in a retrospective study that RIAKI in COVID-19 patients tended to have elevated levels of C-reactive protein, ferritin, and procalcitonin. These patients also had poorer overall prognoses when compared to COVID-19 patients who have acute kidney injury (AKI) due to other causes. It is clear from these findings that clinicians must closely monitor and assess for the presence of rhabdomyolysis in COVID-19 patients who have developed AKIs. Moreover, additional research is required to further understand the mechanisms behind the development of RIAKI in COVID-19 patients in order to better inform treatment guidelines and protocols.

Core Tip: The article published in the recent issue of the World Journal of Virology (2024) has shown that patients with rhabdomyolysis induced acute kidney injury (RIAKI) as a complication of coronavirus disease 2019 (COVID-19) infection tend to show elevated levels of specific biomarkers. Additionally, patients with RIAKI in COVID-19 infection have worse outcomes compared to patients who have acute kidney injury due to other causes in COVID-19 infection. To improve overall outcomes, there is a need to better understand the mechanism for RIAKI development in COVID-19, and to create evidence-based treatment protocols for this condition. To determine which approaches are most effective, more research on the outcomes for patients with differing treatment regimens is required.
