Objective: The present investigation aims on the clinical attributes and haematological parameters between symptomatic (COVID-19 ICU) and asymptomatic (COVID-19 homes isolation) patients as predisposing sign for COVID-19 related mortality.
Materials and methods: A retrospective cohort research was conducted of admitted patients to ICU, who were suffering from severe COVID-19 in Aseer Central Hospital, Abha, Kingdom of Saudi Arabia (KSA) from July 2020 until September 2020. The study included individuals with COVID -19 and ICU admission as symptomatic group and others who are COVID-19 positives with quarantine as asymptomatic group. Epidemiological, clinical and haematological laboratory data were retrospectively collected, analysed with control subjects.
Results: Of the 38 ICU patients studied, the most common symptoms were fever and respiratory distress (100%), cough (86.8%). Majority were of Saudi origin (78.9%). Eighteen (47.4%) COVID-19 ICU patients showed leukocytosis, 6 (15.8%) had severe thrombocytopenia (with most having thrombocytopenia), 18 (47.4%) were anaemic. A significant correlation was observed between the WBC, RBC, Hb, platelets, neutrophil and lymphocyte count between ICU inmates compared with quarantine (p < 0.001) and RBC, Hb, neutrophil and lymphocyte count with control groups (p < 0.001).
Conclusion: From the observations it is evident that, the blood tests have potential clinical value in predicting COVID-19 progression. Further, patient characteristics including age, leukocyte count, RBC, platelets and differential leukocyte counts may be significant predictors for monitoring the progression of the critical illness observed in SARS-COV-2 patients. Also, treatment procedures can be re-defined further to reduce COVID-19 mortalities in more critically ill COVID-19 individuals.
