Serum zinc level independently predicts need for inpatient intubation among patients hospitalized with COVID-19: A prospective observational study.

What Was Tested

The paper reports a study of Vitamin D, K2, Magnesium and Zinc, published as an observational study.

Further study of modifiable factors influencing COVID-19 severity and outcomes continues to be necessary.

Serum zinc levels may play a role in modulating COVID-19 virus replication and consequently influence clinical outcomes.

Who Took Part

PubMed indexes the participants as adults, middle-aged adults, older adults and people over 80, both men and women.

This was a prospective observational study of adult patients hospitalized with COVID-19 assessing the relationship between serum zinc levels and clinical outcomes.

The primary outcome was the need for intubation at any time during inpatient stay.

How the Study Was Run

Secondary outcomes included hospital disposition and incidence of shock and acute kidney injury.

What Was Measured

Further study of modifiable factors influencing COVID-19 severity and outcomes continues to be necessary.

Serum zinc levels may play a role in modulating COVID-19 virus replication and consequently influence clinical outcomes.
