Association of serum zinc level and clinical outcome in Egyptian COVID-19 patients
The Egyptian Journal of Internal Medicine, doi:10.1186/s43162-022-00159-z
Background: Zinc is an anti-inflammatory and antioxidant micronutrient found in food. Due to its well-established role in immunity, it is currently being used in some clinical trials against coronavirus disease-2019 . This study aimed to assess the association between the mean serum zinc level in COVID-19 Egyptian patients and its relationship with disease severity. This cross-sectional study was conducted on sixty patients with confirmed COVID-19 infection. These patients were divided into two groups according to clinical outcome, group 1 which included 30 intensive care unit (ICU) patients and group 2 which included 30 patients who were admitted to the ward. Mean serum levels of zinc were compared between the two groups. Results: There was a statistically significant difference noted among study groups regarding the serum zinc level (p < 0.039), where lower mean serum zinc levels were noted in ICU patients compared to ward patients (70.6 ± 5.7 vs 73.8 ± 6.1).
Conclusion: Low serum zinc level is associated with the severe outcome of COVID-19 infection.
