Secondary bacterial infection caused by ST16 NDM-1 and OXA-48-producing colistin and carbapenem-resistant Klebsiella pneumoniae treated with tigecycline in a pregnant woman with COVID-19

Abstract

AbstractDuring the COVID-19 pandemic, the rapid emergence of carbapenem and colistin-resistant Klebsiella pneumoniae has resulted in an alarming situation worldwide. We aimed to describe secondary infections and antimicrobial use, in a pregnant woman admitted to hospital with COVID-19. A 28-year-old pregnant woman was admitted to the hospital due to COVID-19. According to the clinical conditions, the patient was transferred to the ICU on the second day. She was empirically treated with ampicillin and clindamycin. Mechanical ventilation through an endotracheal tube was started on the 10th day. During her hospitalization in the ICU, she was infected with ESBL-producing K. pneumonia, Enterobacter spp and carbapenemase-producing colistin-resistant Klebsiella pneumoniae isolates. Finally, the patient was treated with tigecycline monotherapy that was associated with ventilator-associated pneumonia clearance. Bacterial co-infection is relatively infrequent in hospitalized patients with COVID-19. Treatment of infections caused by carbapenemase-producing colistin-resistant K. pneumoniae isolates is challenging, with limited antimicrobials available in Iran. In order to prevent the spread of extensively drug-resistant bacteria, infection control programs must be implemented more seriously.
