A study of some physiological parameters in patients previously infected with COVID-19

Coronavirus disease 2019 (COVID-19), a potentially fatal illness brought on by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), had emerged posing a threat to public health throughout the world. The aim of study is evaluation the effect of Covid-19 disease on some physiological and hematological indicators of Covid-19 patients and to use as a parameter for monitoring the disease severity. This study as retrospective study was performed at the Al-Imam Hussein Teaching Hospital (January 2021 - April 2021) including 30 Covid-19 patients who were in between the ages of 18 and 84 (15 male and 15 female patients) and another 30 individuals patients who were in between the ages of 18 and 82 (15 male and 15 female individuals) as control group. The patients were previously diagnosed with Covid-19 disease using PCR. Our findings demonstrated that values of physiological and blood markers in COVID-19 varied significantly, where the random blood sugar was the highest parameter with a significant significance based on the chi-square test (P-value = 0.03) and the age group, most affected by the high concentrations of clinical parameters was 63-77 years old, while the least affected age group was 18-32 year. Our findings showed an increase in the concentrations of clinical parameters in males compared to females, where the random blood sugar was of a significant difference based on the chi-square test (P-value = 0.036). This study found that various physiological and blood indicators significantly increased in Covid-19 patients, where they suffer from an increase in blood urea nitrogen, serum creatinine, ferritin random blood sugar as a result of the virulence of the virus and its attack on pulmonary and renal cells, So, monitoring the increase in these parameters may contribute to know the severity of disease.
