Coronavirus disease 2019 (COVID-19) and tuberculosis are serious and mortal diseases worldwide. There are few studies about the association between tuberculosis and COVID-19 pneumonia. We aimed to describe the characteristics of tuberculosis and COVID-19 co-infection cases in light of the literature.
Tuberculosis patients who applied to the tuberculosis outpatient clinic between September 1-September 30, 2020, and patients hospitalized in the COVID-19 service between June 1- September 30, 2020, were retrospectively screened. Patients with tuberculosis and COVID-19 co-infection were recorded. Clinical, radiological, laboratory data, and treatments were recorded and analyzed. For the diagnosis of tuberculosis, sputum acid-resistant bacillus (ARB) smear or culture positivity or pathological diagnosis were used. For the diagnosis of COVID-19, positive real-time reverse transcription-polymerase chain reaction and/or typical radiological findings were sought.
Seven hundred and fifty-one patients' data at the tuberculosis outpatient clinic, 229 patients' data at the COVID-19 clinic were screened. Sixteen patients meet the criteria. COVID-19 infection rate in tuberculosis patients was 2.1%. Sixty-nine percent of the patients had received COVID-19 disease during diagnosis or initial tuberculosis treatment phase. There were no drugdrug interactions between anti-tuberculosis drugs and COVID-19 treatment. During the COVID-19 treatment, one patient (6%) died, 15 (94%) patients completed the treatment.
: In our study, no effect of the coexistence of TB and COVID-19 on morbidity or mortality was observed. Although the number of patients is small, it can be said that patients with early TB disease and with widespread involvement may be riskier for COVID-19 infection. Frequent hospital visits by TB patients may be a risk for COVID-19. It may be beneficial to carry out the diagnosis and treatment of tuberculosis patients by tuberculosis dispensaries as in our country or authorized units to reduce the risk of hospital admissions and COVID-19 transmission.
