Abstract
Background
There seems to be a gap in the therapeutic options for severe Covid-19 pneumonia. Though the beneficial effect of combination treatment with baricitnib and remdesivir in accelerating clinical status improvement is described, the impact of the triple therapy with baricitinib + remdesivir/dexamethasone is not known.
Methods
A retrospective observational study comparing the effect of baricitinib plus standard treatment (remdesivir and dexamethasone) with standard therapy in patients requiring ≥ 5 L/min O2 was conducted. The primary outcome was to compared time to recovery in both groups, and the secondary outcomes was to determine mortality rate at discharge.
Results
Of 457 patients hospitalized during the study period, 51 patients received standard treatment while 88 patients received baricitinib plus standard treatment. In baricitinib group, the rate ratio of recovery was 1.28 (95%CI 0.84-1.94, p=0.24) with a reduction in median time to recovery of 3 days compared to standard treatment group. Subgroup analysis based on Ordinal Scale showed reduction in median time to recovery by 4 and 2 days with rate ratio of recovery of 2.95 (1.03-8.42, p =0.04) and 1.80 (1.09-2.98, p=0.02) in Ordinal Scale 5 and 6 respectively. No benefit was found in the Ordinal Scale 7 subgroup. An overall decrease in rate (15.9% vs 31.4% p=0.03) a likelihood (OR 0.41, 95%CI 0.18-0.94, p=0.03) of mortality was observed in the baricitinib group. Bacteremia and thrombosis were noted in the Baricitinib group, but comparable with the Standard of care group.
Conclusion
Baricitinib with standard therapy reduced time to recovery and offer mortality benefit in patients with severe COVID-19 pneumonia.”

Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:Our study had several limitations; firstly, this retrospective observational study included two groups of hospitalized COVID-19 pneumonia patients from two different timeframes (July-Dec 2020 and Jan-Feb 20, 2021). Though these groups had a similar distribution in demographic, baseline characteristics, and burden of the disease, we accept that there were confounders including “variants of concern” and mortality differences due to comparatively lesser burden of disease in the July-Dec timeframe. The study is also limited by sample size and generalizability. There was no standard length of therapy for the baricitinib-treated group and ranged from 3 to 10 days. The decision to stop baricitinib was at the discretion of the treating physician based on the patient’s clinical improvement. Thirdly we had two patients still hospitalized on mechanical ventilation, without a clear outcome, when the data was analyzed. Fourthly, the inherent limitations of retrospective studies, especially lack randomization, cannot be ignored, though we believe our encouraging results contribute to the therapeutic options for hospitalized severe COVID-19 patients till further robust data/evidence is available. Lastly, the lack of benefit in patients requiring mechanical ventilation could be due to the smaller sample size.
