Biochemical and Familial Factors Influencing COVID-19 Disease Progression

COVID-19 is a global pandemic that has caused significant mortality. The disease severity varies among individuals, and the factors influencing its course remain unclear. This study aimed to investigate the influence of biochemical parameters and familial data on COVID-19 outcomes. A retrospective analysis of 122 COVID-19 patients was conducted. Patients were categorized into two groups: outpatients with mild symptoms and those admitted to the intensive care unit (ICU) and intubated. Demographic data, biochemical levels of vitamin D, vitamin B12, and magnesium, and COVID-19 outcomes of first-, second-, and third-degree relatives were collected. The ICU group had a higher proportion of males (75%) and older patients (average age: 63.18±12.89 years) than the outpatient group (40% males and an average age of 45.13±13.77 years). Both groups had similar BMI, vitamin D, and vitamin B12 levels. However, magnesium levels were significantly higher in the ICU group (mean 2.25±0.3 mg/dL) than in the outpatient group (mean: 1.98±0.2 mg/dL). A significant familial relationship was identified between COVID-19 outcomes and disease course. Among the ICU patients, 25% had first-degree relatives who died from COVID- 19, compared to only 10% of the outpatient patients. Similarly, second- and third-degree relatives of ICU patients had a higher mortality rate from COVID-19 than relatives of outpatient patients. Age, gender, and magnesium levels may influence COVID-19 disease severity. Familial ties (genetic relatedness) may also play a role, suggesting potential genetic predisposition. Further research is needed to validate these findings and elucidate the underlying mechanisms
