Evaluation of the effects of anakinra treatment on clinic and laboratory results in patients with COVID-19.

Objective: Some anti-cytokine treatments are being used to control the hyperinflammatory condition defined as cytokine storm that develops during COVID-19 infection. In this study, we aim to investigate the effects of anakinra, an IL-1 antagonist, on the clinical status and laboratory values of hospitalized patients with the COVID-19 infection. The aim of the study was to investigate the effects of anakinra, an IL-1 antagonist, on the clinical and laboratory results of hospitalized patients with COVID-19 infection.

Methods: This study was planned as a retrospective study. The age, gender, and current comorbidities of a total of 66 patients who were treated with anakinra for COVID-19 infection from November 2020 to January 2021 were analyzed. The amount of oxygen demand (L/s), the type of oxygen supplementation, oxygen saturation, radiological findings, WBC count, lymphocyte count, neutrophil count, C-reactive protein, LDH, ferritin, fibrinogen, D-dimer levels were monitored before the treatment, and after the anakinra treatment, newly gathered results were compared. Patients' hospitalization period, oxygen need, and their clinical status at discharge were evaluated. The effects of early anakinra treatment (9 days before and after the onset of symptoms) on the prognosis were evaluated. SPSS version 21.0 provided by IBM Company in the USA, Chicago, IL was used for statistical analysis and p<0.05 was considered significant.

Results: Sixty-six patients were included in the study. There was no significant gender difference in the prognosis of the patients. There was a significant difference in the statistical deterioration in patients with comorbidities (p=0.004). Patients who started the anakinra treatment at an early stage developed less need for intensive care and low mortality ratios (p=0.019). There were significant improvements on the levels of WBC (p=0.045), neutrophils (p=0.016), lymphocyte (p=0.001), LDH (p=0.005), ferritin (p=0.02), and fibrinogen (p=0.01) after the administration of anakinra therapy.

Conclusion: We found that earlier and appropriate use of anakinra therapy in COVID-19 patients with the signs of macrophage activation syndrome reduces the need for oxygen support in patients and contributes to improvement in laboratory results and radiological findings, and most importantly reduces the need for intensive care.
