Outcomes following peritoneal dialysis for COVID-19-induced AKI: A literature review

Acute kidney injury (AKI) has been shown to be associated with significant morbidity and mortality in patients with severe COVID-19 disease. Due to increasing number of cases in pandemic, there is a significant shortage of medical facilities and equipment in relation to patient load. In low resource settings where access to intermittent haemodialysis (HD) or continuous kidney replacement therapy (CKRT) is limited, peritoneal dialysis (PD) may play a vital role in the management of COVID-19-induced AKI. A literature search using Medline/PubMed, Embase, Google Scholar and Cochrane register was performed using following search strategy: (((COVID 19) OR (SARS-CoV-2)) AND (((acute kidney injury) OR (acute renal failure)) OR (acute renal dysfunction))) AND (peritoneal dialysis). Search strategy yielded total 79 articles. After going through titles and abstracts, full text of 15 articles was obtained. Finally, six studies were included in the review after exclusion of 10 studies. Five studies were single centre and one study was multicentric; four studies were conducted in the United States and one in the United Kingdom; PD catheter placement was done by surgeons in three studies and by nephrologist in one study. The mortality reported in the studies varied from 43% to as high as 63%.
