RIQUELME, Irma et al. Carbapenemase-producing microorganisms in clinical samples of inpatients of Hospital de Clínicas during the years 2020-2021. Rev. Inst. Med. Trop. [online]. 2022, vol.17, n.2, pp.4-12. ISSN 1996-3696.  https://doi.org/10.18004/imt/2022.17.2.2.

The World Health Organization has declared antimicrobial resistance one of the top 10 public health threats facing humanity. Currently, enzymes from the families Klebsiella pneumoniae carbapenemase (KPC), Oxacillinase (OXA), New Delhi Metallo-beta-lactamase (NDM), Verona Integron En coded Metallo-beta-lactamase (VIM) and Imipenemase (IMP) are those that are more frequently detected worldwide. The objective is to describe the findings of the isolates of carbapenemase-producing microorganisms from patients hospitalized at the Hospital de Clínicas during the years 2020 and 2021. A retrospective descriptive cross-sectional study of data obtained from the Hospital's microbiology laboratory was carried out between January 2020and December 2021. 216 clinical samples were studied, of which 196 (91%) were in adult patients, 172 (80%) were positive for metallo-β-lactamase (MBL) enzymes, Klebsiella pneumoniae was the most frequent species. In patients hospitalized in the Intensive Care Unit these isolates predominated and in urine samples 91 (42%). According to sex, 108 (50%) for both sexes and a median age of 52 years, with a range of 6 days to 92 years. Regarding the number of isolates found, it was higher in 2020 with 121 (56%). Active surveillance together with infection control measures are necessary to limit the spread of carbapenemase-producing microorganisms, in addition, there are necessary data to justify the introduction of antibiotics of choice for these microorganisms into the country.
