Kidney injury molecule-1: potential biomarker of acute kidney injury and disease severity in patients with COVID-19

Abstract: Aims The aim of the current study was to evaluate whether tubular markers kidney injury molecule-1 (KIM-1) and N-acetyl-ß-glucosaminidase (NAG) are related to acute kidney injury (AKI) and severe disease in patients with COVID-19. Methods and results In this prospective observational clinical trial we examined a cohort of 80 patients with proof of acute respiratory infection and divided them into a COVID-19 cohort (n = 54) and a control cohort (n = 26). KI… Show more

“…Elevated KIM-1 levels correlated with a decline in eGFR in a study including 4750 patients followed for more than 10 years 150 . Manuel J et al also found KIM-1 in patients with COVID-19 might provide additional value in recognizing AKI at an early stage of disease in a cohort of 80 patients with COVID-19 151 . However, AKI is serious when the concentration of KIM-1 in blood or urine increased.…”

“…Hyperkalemia has been observed in 23% of patients with COVID-19 AKI and is often associated with metabolic acidosis [ 44 , 45 ]. Although urinary kidney injury molecule 1 (uKIM-1) was shown to be a predictor of mortality in COVID-19 AKI [ 46 ] and damage at the level of the podocyte and renal tubule is important [ 24 ], multiple factors may be associated with damage at the same site, making it difficult at this time to separate the cytopathic component of the virus from other pre-existing and associated morbid conditions.…”

“…Moreover, KIM-1 is also identified as a hepatitis A virus cell receptor 1 (HAVCR-1) that is expressed by on the surface of different epithelial cells and facilitates cellular entry of several viruses, including Ebola virus, dengue virus, West Nile virus, and hepatitis A virus, via the IgV domain [ 115 ]. A recent report suggested that KIM-1 was not only a biomarker for COVID-19-associated acute kidney injury (AKI) [ 116 ] but also a potential receptor for SARS-CoV-2. [ 7 ] SARS-CoV-2 was reported to directly infect the renal tubules by ACE2 and induced AKI, which is one of the most prevalent complications among hospitalized COVID-19 patients [ 117 ].…”
