Abstract

COVID-19-related disease severity is more commonly seen in elderly patients with comorbidities, and hypercoagulability has been demonstrated to be involved in the disease progression. This study aimed to evaluate the level of D-Dimer in hospitalized SARS-COV-2 infected patients and to determine the influence of age, gender, Body Mass Index (BMI), and comorbidities on D-dimer value and correlate it with disease severity. This case-control retrospective study retrieved patient data on demographic characteristics, vital functions, comorbidities, disease severity [National Institutes of Health (NIH) classification], and D-dimer from medical records of Thumbay University Hospital, Ajman, United Arab Emirates. SPSS-Version-28 was used for data analysis; a Chi-Square test was done to compare the distribution of comorbidities and disease severity between demographic categories. An independent sample t-test and one-way ANOVA were done to compare mean levels of D-Dimer between two or more categories, respectively. The majority of patients were males, ˃40 years of age, overweight/obese, with 30% having one comorbidity and 20% having ≥2 comorbidities. Among the total, three-quarters had moderate, and one-quarter had severe disease conditions, irrespective of gender or BMI, with an increasing trend of severe cases in the older age group and with comorbidities. Increased D-dimer levels were seen in the majority of SARS-COV-2-infected hospitalized patients, with age as the primary determinant, irrespective of absence or presence of comorbidity, though the trend of higher prevalence of elevated D-dimer value in the multiple comorbid groups and more severe condition was observed. Supporting SAR-COV-2 as a coagulopathic condition, D-dimer concentrations can be a helpful marker of disease progression and can be considered to guide the clinical treatment.
