Clinical Report: Ischaemic Heart Disease and Genetic Factors in Severe COVID-19 in Uzbekistan

Overview

This retrospective study of 227 Uzbek COVID-19 patients identified ischaemic heart disease (IHD) as a significant clinical risk factor for severe COVID-19 outcomes. Additionally, the ACE I/D rs1799752 and IL28B rs12979860 gene polymorphisms were investigated for associations with disease severity, highlighting the importance of host genetic and clinical factors in COVID-19 progression.

Background

COVID-19 severity varies widely, influenced by viral and host factors including age, comorbidities, and genetic polymorphisms. Genetic variations such as ACE I/D and IL28B rs12979860 polymorphisms have been implicated in COVID-19 susceptibility and severity but remain controversial due to heterogeneous study designs. Understanding allele frequencies in specific ethnic populations like Uzbeks is critical for personalized medicine and accurate risk assessment. This study aimed to identify clinical and genetic factors associated with severe COVID-19 in Uzbek patients.

Data Highlights

Key Findings

• Ischaemic heart disease was significantly associated with severe/extremely severe COVID-19 outcomes in Uzbek patients.
• ACE I/D rs1799752 polymorphism showed variable allele frequencies in the Uzbek population, consistent with global ethnic variability.
• IL28B rs12979860 polymorphism was analyzed but its association with COVID-19 severity was not conclusively established.
• Age and comorbidities remain important clinical factors influencing COVID-19 severity.
• Genetic polymorphisms may interact with clinical factors to modulate disease risk and severity.

Clinical Implications

Clinicians should consider ischaemic heart disease as a key risk factor when assessing COVID-19 severity risk in Uzbek patients. Genetic testing for ACE I/D and IL28B polymorphisms may provide additional insights but requires further validation before routine clinical use. Personalized treatment strategies integrating clinical and genetic data could improve patient outcomes.

Conclusion

This study underscores the significant role of ischaemic heart disease in severe COVID-19 among Uzbeks and highlights the need for further research on genetic polymorphisms to refine risk stratification and personalized care approaches.
