Toclizumam Versus Dexamethasone in Severe Covid-19 Cases

The current study takes place in the ICU of ESNA hospital, the first COVID-19 quarantine hospital in Egypt, located in Upper Egypt, Luxor governorate during the period from March 2020 to June 2020.

The diagnosis of COVID-19 was made with a positive RT-PCR assay performed on a nasal swab. We have collected data on patients' demographics, comorbidities, symptoms, oxygen support, the ratio of partial pressure of arterial oxygen over the fraction of inspired oxygen (PaO2/FiO2 ratio), laboratory values (complete blood count, CRP, D-Dimer, ferritin, AST, ALT), diagnostic workup, therapies, complications, and outcomes.

Patients were given conventional treatment for COVID-19, including, hydroxychloroquine with a loading dose of 400 mg twice daily followed by 200 mg per day twice daily for additional five days and azithromycin 500 mg per day for five days unless contraindicated. An electrocardiogram was obtained for each patient to check the corrected QT interval at baseline.

In addition to conventional treatment, patients were randomly assigned to either dexamethasone group or tocilizumab (TCZ) group according to random tables.

Eligibility for study included patients with significant deterioration in respiratory clinical status with respiratory rate > 30 cycle/minute, Bilateral CT infiltration > 30%, PaO2/FiO2 ratio <150 or saturation <90 on >6L/min, Two positive laboratory tests of: (CRP>100 g/dL, lymphocytes<600 /mm3, D dimer>L, Ferritin >500).Interleukin 6 levels were not part of the criteria because it did not necessarily result in an actionable time frame.
