Abstract

Tocilizumab (TCZ) is a promising treatment for management of COVID-19 pneumonia amid many controversies linked to its potential benefit. The exact time for administration of the drug to avail maximum clinical benefit is still unclear. We present a case series in which three patients with severe COVID 19 (respiratory rate of more than 30/min, breathlessness and hypoxia with Spo2<92>75 mg/dl, IL-6 > 200 pg/ml and ABG depicted falling trend in Pao2/Fio2 ratio despite adequate ventilation. These patients received TCZ nearly 9to 14 days of ICU stay after excluding secondary bacterial and fungal infections (sputum, urine and blood culture) as their inflammatory markers increased suddenly during the late phase of the disease. Their liver and kidney functions were acceptable and no neutropenia or thrombocytopenia was ensured. Their inflammatory markers improved significantly post intervention and they weaned from non-invasive ventilation, transferred from the intensive care unit to the ward and later discharged in 20-25 days from the hospital.Therefore, we would like to emphasize consideration of TCZ in worsening critically ill COVID-19 patients as a pharmacological modality even during late phase of the disease as a means to improve oxygenation, avoiding mechanical ventilation and subsequent morbidity and mortality. COVID 19 is a dynamically evolving disease and new treatment modalities at the different stages of the disease may yield benefits in certain sub-groups of patients.
