Acute kidney injury outcomes in covid-19 patients: systematic review and meta-analysis

Abstract

Background: Acute kidney injury (AKI) is a frequent complication of coronavirus-19 disease (COVID-19). Therefore, we decided to perform a systematic review and meta-analysis with data from the literature to relate the development of COVID-19 associated-AKI with comorbidities, medications, and the impact of mechanical ventilation. Methods: We performed a systematic review using the Newcastle-Ottawa scale and a meta-analysis using the R program. Relevant studies were searched in the PubMed, Medline, and SciELO electronic databases. Search filters were used to include reports after 2020 and cohort studies. Results: In total, 1166 articles were identified and 55 English-written articles were included based on the risk of bias. Of all COVID-19-hospitalized patients presenting with AKI (n = 18029) classified as Kidney Disease Improving Global Outcomes stage 1 to 3, approximately 18% required mechanical ventilation and 39.2 % died. Around 11.3% of the patients required kidney replacement therapy (KRT) and of these, 1093 died and 321 required continuous KRT. Death is more frequent in individuals with AKI [OR 6.03, 95%CI: 5.73-6.74; p<0.01]. Finally, mechanical ventilation is an aggravating factor in the clinical conditions studied [OR 11.01, 95%CI: 10.29-11.77; p<0.01]. Conclusion: Current literature indicates AKI as an important complication in COVID-19. In this context, we observed that comorbidities, such as chronic kidney disease and heart failure, were more related to the development of AKI. In addition, mechanical ventilation was seen as an aggravating factor in this scenario.

Outcomes, Risk Factors, and Incidence of Acute Kidney Injury in Hospitalized COVID-19 Patients

“…In three different studies carried out by Cheng, Li, and Ng on AKI in COVID-19 patients, the incidence of AKI was reported to be between 5.4% and 39.9%, and mortality in these patients was 30% to 40% (22)(23)(24). Moreover, Silva et al, in a systematic review, reported an incidence rate of 31% for AKI, and the mortality of 39.2% in these patients (25). Although the AKI incidence rate in our study was compatible with their findings, the mortality rate was higher.…”

Global Perspectives in AKI: Peru

“…11 These results differ from those of some systematic reviews that show a lower incidence and higher mortality particularly in ICU patients worldwide. 12,13 This difference could probably be related to the delayed medical care caused by the saturation of Peruvian hospitals during the first and second waves of the pandemic and the prioritization of ICU admission of patients with better prognosis. 14…”

Ativação do inflamassoma: a importância na leishmaniose, na influenza e na COVID-19

“…Os sintomas mais comuns são anosmia, hipogeusia, tosse, febre, mialgia, dispneia e dor de cabeça (Brann et al, 2020;Burke et al, 2020;Stokes et al, 2020;Butowt and Von Bartheld, 2021). Complicações extrapulmonares também têm sido descritas para a COVID -19, como dano renal (Robbins-Juarez et al, 2020;Yang et al, 2020;Silva et al, 2022), trombose (Bohula et al, 2022;Ns et al, 2022;Peacock et al, 2022) e manifestações neurológicas (Chou et al, 2021;Graham et al, 2021;Macintosh et al, 2021;Song et al, 2021;Olivarria et al, 2022).…”
