To determine the effectiveness of Tofacitinib on treatment outcome in patients hospitalised with COVID-19 pneumonia- A longitudinal observational study in a tertiary care Hospital Mandya

Abstract

The effectiveness of Tofacitinib, a Janus kinase inhibitor, in patients who are hospitalised with coronavirus disease 2019 (COVID-19) pneumonia are unclear hence this study is conducted to evaluate the efficacy of Tofacitinib on treatment outcome in patients hospitalised with COVID-19 pneumonia.All diagnosed cases of SARS COV2 who required O2 therapy at the start of the study will be undergoing routine investigations according to COVID 19 management guidelines and will be treated with adequate immunosuppression with corticosteroids. Those patients whose inflammatory markers (CRP, S LDH, D DIMER) are not decreasing after 48 hours of corticosteroids therapy may be given Tab Tofacitinib 10mg bid for a period of 14 days or till the decrease in inflammatory markers, whichever is earlier. Oxygen requirement and inflammatory markers were assessed every 3 day. Out of 27 patients who didn’t respond for corticosteroids 20 were given the drug tab tofacitinb 10mg BD. CRP in the both the steroid non responders and steroid responders groups was high till day 9, on day 14 the CRP levels were normal in 50% of steroid non responders. S LDH levels in the steroid non responders group was in the decreasing trend i.e., on day 14 it was normal in 70% of patients.. The levels of D DIMER in tofacitinib group was high till day 6, and on day 14 the D-DIMER levels were normal in 40% patients. Oxygen requirement showed drastic changes in the steroid non responders group. Among patients hospitalized with COVID-19 pneumonia, addition of Tofacitinib to steroid non responders group showed early improvement in their clinical and biochemical levels. Hence, Tab tofacitinib can be recommended an adjunct to steroids for early clinical and biochemical improvement for treatment of moderate to severe cases of COVID-19.
