Background: Several lines of evidence suggest that SARS-CoV-2 invasion of the central nervous system leads to meningitis and encephalopathy syndromes. Additionally, chronic alcoholics were found to be at a higher risk of developing mental health problems and serious neurological manifestations, if exposed to SARS-CoV-2 infection.
Methods: Herein, we studied RNA seq data from alcoholics’ brain tissue and COVID-19 patient’s brain tissue to identify the common differentially expressed genes.
Results: Overlap analysis depicted the expression of seven genes ( GHRL, SLN, VGF, IL1RL1, NPTX2, PDYN , and RPRML ) that were significantly upregulated in both groups. Along with these, protein-protein interaction analysis revealed 10 other key molecules with strong interactions with the aforementioned genes.
Conclusions: Taken together with the functional effect of these genes, we suggest a strong molecular link between COVID-19-induced severities and neurological impairment in patients suffering from alcohol abuse disorder. These findings emphasize the importance of identifying chronic alcoholism as a risk factor for developing cognitive and memory impairment in COVID-19 patients.
