Association between thrombocytopenia and mild infection of COVID-19 patients

Association between thrombocytopenia and the severity of Covid-19 infection among hospitalized Egyptian patients

“…Cough was more common in severe patients' group or critically ill. This result agreed with the study by Yameny, who found that, fever was higher among moderate patients'group while dyspnea and cough were statistically higher among critically ill patients'group [ 21 ]. Additionally, World Health Organization, [ 24 ] In severe cases, infection can cause pneumonia, severe acute respiratory syndrome and sometimes death, that were increased in critically ill patients.…”

“…There were no statistically significant differences among the studied groups as regard age and gender. These results agreed with the study by Yameny, performed on 504 patients their aged ranged from 20 years to 75 years with mean age 44.5 ± 30.5, male gender was more frequent than female gender with no statistically significant differences [ 21 ]. Also, the study by Zhu et al, performed on 167 COVID-19 patients, and their age ranged from 29 to 93, female was frequent in 67.07% [ 22 ].…”

“…The study agrees with Yameny, found a significant value with critically ill infection as ferritin level which increased in 71.4% LDH has a high level in 67.7% and D-dimer has positive results in 36.4% [ 21 ]. Also, the study by Wool and Miller, reported that, temporally increasing D-dimer levels indicate the progressive severity of COVID-19 infection and can be used as a predictor that more aggressive critical care will be needed [ 27 ].…”

COVID-19 Laboratory diagnosis methods

“…Patients with mild symptoms have a modestly elevated platelet count, whereas severe COVID-19 infections are characterized by thrombocytopenia (40). But a study in Egypt showed Platelet count was normal, and Platelet was not a significant biomarker for COVID-19 diagnosis or prognosis in out-hospitalized patients (Outpatients and patients under home observation) (41).…”
