Background And AimDifferent side effects, including infections, are encountered in patients receiving anticytokines used for the treatment of severe coronavirus disease 2019 (COVID-19). The aim of this study was to evaluate the infections and the effects of these infections that develop in this patient group.Materials And MethodsThis study included 208 patients who were followed-up with the diagnosis of severe COVID-19 in two different hospitals. Patient data were obtained retrospectively from the hospital information system.ResultsOf the 208 patients included, 54 were in the anakinra group, and 154 were in the tocilizumab group. Of these patients, 73 (35.1%) developed infection, 160 (76.9%) were admitted to the intensive care unit (ICU), and the 30-day mortality rate was 46.6%. The ICU admission, 30-day mortality, and infection rates were higher in the anakinra group, but it was not statistically significant (p = 0.137, p = 0.127, and p = 0.132, respectively), while pneumonia and bloodstream infection (BSI) rates were higher (p = 0.043 and p = 0.010 respectively). The 30-day mortality rate was significantly higher in patients who developed infection, especially in the tocilizumab group (p < 0.001 and p = 0.001). The independent risk factors affecting the development of infection were evaluated via regression analysis, in which it was found that age, sex, and the type of immunosuppressive treatment had no significant effect, while ICU admission increased the risk of infection by 32.8 times (95% CI: 4.4-245.8) and each day of hospitalization slightly increased the risk of infection by 1.06 times (95% CI: 1.03-1.09).ConclusionInfection rates were higher in the anakinra group, especially the pneumonia and BSI rates were higher than in the tocilizumab group. The 30-day mortality rates were higher in patients who had an infection, especially in the tocilizumab group. This is one of the rare studies that evaluated infections developing in patients treated with anakinra and tocilizumab together.© TÜBİTAK.
