For COVID-19 treatment, the
kidney biopsies of COVID-19 patients with AKI (acute kidney injury) may help to
better understand the underlying pathophysiologies of COVID-19 at a cellular
and molecular level.
A novel analysis documented
that about one-third of US COVID-19 hospitalized patients developed AKI (acute
kidney injury) syndrome. Approximately 15% of them needed dialysis. According
to experts, more robust research into multiple aspects of this increasingly
pivotal issue is required. Between March and April 2020, among 5449 subjects
admitted to 13 Northwell Health New York-based hospitals, 36.6% of them
developed AKI syndrome.
AKI disorder is closely connected with respiratory collapse and was hardly
found to be a severe disorder among patients requiring no ventilation. Among
ventilated patients, the kidney injury rate was 89.7% in comparison with 21.7%
among other patients as illustrated in the following table:
AKI in COVID-19 was also associated with a poor prognosis i.e. 35% of those who developed AKI had passed away at the time of publication. Data of New York hospitals indicated that severe kidney damage was developed in around 31% of critically ill subjects requiring dialysis. Scientists of NIDDK (National Institute of Diabetes and Digestive and Kidney Diseases) has outlined the AKI significance as the viral pandemic's sequela.
Since numerous hospitals are expected to face COVID-19 subjects with this
complication, clinicians should try to better comprehend what is occurring.
There is a requisition of unraveling the natural history and heterogeneity of
the kidney disorder. Extremely ill COVID-19 patients instantly develop kidney
failure as their condition worsens rapidly.
Clinical trials are warranted to examine therapeutic interventions that would
mitigate COVID-19–induced AKI since low kidney function is an exclusion
criterion in all the current studies. Recognizing AKI development risk factors
in COVID-19 subjects will be essential in helping shed more light on predictive
and diagnostic biomarkers.
Kidney biopsies from COVID-19 patients with early AKI could help us to target
specific treatments to specific subgroups of patients. A NOSI (Notice of
Special Interest) has been recently issued by NIDDK that has highlighted the
most urgent regions in requisition of research, with one of the major goals
being on the kidney.
