HEMATOLOGICAL CHANGES ASSOCIATED WITH COVID-19 INFECTION IN ADEN/ YEMEN

Chronic Hematological alterations in COVID-19 patients range from mild to severe, with common changes including lymphopenia, neutrophilia, and thrombocytopenia. The gold standard for diagnosis is the polymerase chain reaction (PCR) test, which is highly specific and sensitive for detecting SARS-CoV-2 genetic material. The study was a single isolation center retrospective analysis of 200 patients with COVID-19 confirmed cases. The hematological indicators were taken after sample blood collected from the staff of Central Public Health Laboratory to determine the changes, and compared between different grades of severity and prognosis with the hematological indicators. The data was analyzed using Statistical Package for the Social Sciences (SPSS) version 22.0. simple frequencies and percentage were used, while chi-square test used to determine the association between variables. Males consisted 73.5% in this study, while 63% of participants suffered from moderate severity. Related to the hematological changes; and comparisons made according to real-time PCR test results revealed that the Lymphocytopenia and leukocytosis presented among 47.5% and 46.5% respectively with significance association with illness severity and outcome of patients with p-value< 0.05. hematological changes in COVID-19 patients are a common and significant aspect of the disease. Lymphopenia, neutrophilia, thrombocytopenia, and increased levels of inflammatory markers are frequently observed. These hematological abnormalities are associated with disease severity, poor clinical outcomes. Blood parameters aid in COVID-19 diagnosis and prognosis, with abnormal hematological parameters providing early evidence. However, interpretation should consider limitations, sample size, and potential biases. Further research needed.
