A recent cross-sectional study conducted from October to December 2023, primarily aimed to analyze the prevalence of Extended-Spectrum Beta-Lactamases producing Gram-Negative Bacteria (ESBL-GNB) and Carbapenem-Resistant Gram-Negative Bacteria (CR-GNB) in the stool samples of patients undergoing hemodialysis in a tertiary care hospital in Palestine. Conducted at the An-Najah National University Hospital, the study evaluated the collected stool samples on appropriate MacConkey-based agar for bacterial analysis and logistic regression to examine potential risk factors. This research stands poised to contribute significantly to managing Multidrug-Resistant Pathogens in high-risk groups and to enhance local understanding of antimicrobial resistance.
Out of 137 collected stool samples, 116 (84.7%) tested positive for ESBL-producing bacteria, and 8 (5.8) samples had carbapenem-resistant bacteria. Analysis of potential risk factors showed a strong correlation between patient age, hypertension, ischemic heart disease, dialysis shift timings, and blood urea nitrogen levels and the incidence of ESBL-GNB colonization. An inverse association, however, was found between carbapenem-resistant bacteria colonization and ischemic heart disease, shedding light on a possible intricate relationship between patient health status and drug-resistant bacterial colonization.
These alarming levels of ESBL-GNB and CR-GNB fecal carriage highlight the danger of antimicrobial resistance globally, specifically multidrug-resistant gram-negative bacteria (MDR-GNB), which have been flagged as serious threats by the Centers for Disease Control and Prevention (CDC). Carbapenem-resistant gram-negative bacteria also pose a severe risk due to their resistance to most antibiotics, often limiting treatment options to last-resort medications.
The research study firmly indicates an urgent requirement for a more profound understanding of the incidence and infection rates of CR-GNB and ESBL-GNB in stool samples, especially in hospital settings, where fecal carriage can exacerbate the risk of subsequent infections. This inquiry is even more crucial in addressing End-Stage Renal Disease as patients with compromised immune systems susceptible to potentially fatal infections, including those caused by MDR pathogens.
The conducted research provides valuable insights into the frequency of fecal CR-GNB in the Palestinian healthcare sector, aiding the creation of efficient control mechanisms to improve patient outcomes. The results underline the potential role of asymptomatically colonized patients as reservoirs for infection spread, underscoring a need for more intensified research in this field.
