Insights
Elevated liver enzymes, specifically alanine aminotransferase (ALT) and aspartate aminotransferase (AST), may indicate an increased risk of coronavirus disease 2019 (COVID-19) recurrence. This finding offers insights for future prevention strategies.
Area of Science:
- Medical Research
- Infectious Diseases
- Hepatology
Background:
- The phenomenon of coronavirus disease 2019 (COVID-19) recurrence has garnered significant scholarly attention globally.
- Understanding risk factors for COVID-19 recurrence is crucial for effective public health management.
Purpose of the Study:
- To investigate potential clinical and biochemical markers associated with COVID-19 recurrence.
- To identify specific indicators that may predict the likelihood of disease re-emergence in patients.
Main Methods:
- A comparative study involving 44 COVID-19 recurrent cases and 32 control cases admitted between February and March 2020.
- Analysis of demographic data, comorbidities, clinical symptoms, and liver enzyme concentrations (ALT and AST).
Main Results:
- Recurrent COVID-19 cases showed significantly elevated concentrations of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) compared to controls.
- Hypertension was the most common comorbidity in recurrent cases.
- Fever and cough were prevalent symptoms in both groups.
Conclusions:
- Elevated ALT and AST levels may serve as predictive markers for COVID-19 recurrence risk.
- These findings could inform future strategies for the prevention and control of recurrent COVID-19 infections.
Abstract:
'Recurrence' of coronavirus disease 2019 (COVID-19) has triggered numerous discussions of scholars at home and abroad. A total of 44 recurrent cases of COVID-19 and 32 control cases admitted from 11 February to 29 March 2020 to Guanggu Campus of Tongji Hospital affiliated to Tongji Medical College Huazhong University of Science and Technology were enrolled in this study. All the 44 recurrent cases were classified as mild to moderate when the patients were admitted for the second time. The gender and mean age in both cases (recurrent and control) were similar. At least one concomitant disease was observed in 52.27% recurrent cases and 34.38% control cases. The most prevalent comorbidity among them was hypertension. Fever and cough being the most prevalent clinical symptoms in both cases. On comparing both the cases, recurrent cases had markedly elevated concentrations of alanine aminotransferase (ALT) (P = 0.020) and aspartate aminotransferase (AST) (P = 0.007). Moreover, subgroup analysis showed mild to moderate abnormal concentrations of ALT and AST in recurrent cases. The elevated concentrations of ALT and AST may be recognised as predictive markers for the risk of 'recurrence' of COVID-19, which may provide insights into the prevention and control of COVID-19 in the future.
