Impact on tuberculosis diagnostic during COVID-19 pandemic in a tertiary care hospital

INTRODUCTION

The aim of this study is to review how did the first three COVID-19 waves affected the diagnostic of tuberculosis and to describe the extra-pulmonary Mycobacterium tuberculosis complex (TB) diagnosis.

MATERIALS AND METHODS

A retrospective observational study was done during the first three waves of pandemic to ascertain the impact on TB samples and to recover the extra-pulmonary TB cases we included the first two years of COVID-19. All relevant data was recovered from hospital and Clinical Microbiology records.

RESULTS

Prepandemic period showed an average of 44 samples per week for TB study; during the first three waves this number dropped to 23.1 per week. A reduction of 67.7% of pulmonary TB diagnosis was observed and an increase of 33.3% diagnosis of extra-pulmonary TB was noted when comparing pre-pandemic and pandemic period.

DISCUSSION

The number of declared cases and samples for TB diagnosis dropped during the first three COVID-19 waves due to the overstretched Public Health System which could lead to a delay in diagnosis, treatment and to the spread of TB disease in the general population. Surveillance programs should be reinforced to avoid this.

Bacterial co-infections in COVID-19 pneumonia in a tertiary care hospital: Surfing the first wave

The aim of this study is to review bacterial isolates from respiratory samples of patients with severe COVID-19 disease during the first 2 months of the first wave in our hospital. A single-center retrospective observational study in critically ill adult patients was performed. A total of 1251 respiratory samples from 1195 patients were processed. Samples from 66 patients (5.52%) were determined to be microbiologically significant by a semi-quantitative culture. All patients received broad spectrum antibiotherapy as an empirical treatment. The isolated bacteria were mainly Enterobacterales followed by Staphylococcus aureus and Pseudomonas aeruginosa. Bacterial co-infections in ICU stay could seem not dependent on the virus that has produced the viral pneumonia similarly as with other respiratory viruses such as Influenza virus.
