Extended-Spectrum Beta-Lactamases (ESBLs) Gene Mutations in Kuwait: How Much Do We Know? Not Much!

Abstract

Antibiotic resistance is a major problem worldwide, especially with the overuse and misuse of antibiotics. This makes it more challenging to treat patients infected with antibiotic-resistant bacteria, with more costs on the health system. This review article describes extended-spectrum β-lactam antibiotics as the most used antibacterial agents, and how bacteria developed beta-lactamases (ESBLs) to resist these antibiotics. The review focuses more on the problem of ESBLs in Kuwait to uncover which ESBLs are present and what ESBL gene mutations have been found in this country. The literature review, surprisingly, revealed a limited number of studies in Kuwait on ESBL gene mutations, published over the last 25 years. The results showed that Kuwait has an alarming number of bacterial strains with ESBL gene mutations. These studies reported different mutations in different bacterial strains isolated from different types of specimens, which were collected from different hospitals in Kuwait. The data from these studies were scattered and not linked or analysed together to highlight the big picture of the problem of ESBLs in Kuwait. This review article highlights that the amount of research on ESBLs in Kuwait is not up to the expectations of a country like Kuwait, which has high-standard research facilities. Bearing in mind that the geographic area of Kuwait is relatively small, the authors of this paper think that there might be more β-lactam bacteria spreading in Kuwait, which need to be explored, and that more research and more collaboration are needed among researchers in Kuwait to address this risky situation.
