RESUMO
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has challenged healthcare systems worldwide since late 2019. The interleukin-6 inhibitor tocilizumab is one of the most studied agents with a proven benefit for patients with severe and critical coronavirus disease 2019 (COVID-19) pneumonia. Known adverse effects of this agent include upper respiratory tract infections, headache, hypertension, and transaminitis. The risk of secondary bacterial complications among patients who were given tocilizumab remains unclear. A descriptive study was done that included all laboratory-confirmed COVID-19 patients with a severe or critical severity for the year 2021 who received at least one dose of tocilizumab. Of the 1220 laboratory-confirmed COVID-19 patients admitted to Manila Doctors Hospital in the year 2021, a total of 139 patients fulfilled the inclusion criteria and were included in the study. Twenty-one patients, or 15% of the study population, were diagnosed with hospital-acquired pneumonia. This value was similar to previous studies showing the prevalence of secondary bacterial infections among patients who were given tocilizumab. These values could potentially aid clinicians when deciding whether or not to give one or two doses of tocilizumab to patients with severe or critical COVID-19 pneumonia. Given that many patients who are admitted with severe or critical COVID-19 pneumonia often have multiple decompensated comorbidities, the decision to give tocilizumab to manage severe COVID-19 should be weighed against the risk of hospital-acquired pneumonia.
