Epidemiology, clinical profiles, and antimicrobial susceptibility of Elizabethkingia meningoseptica infections: Insights from a tertiary care hospital in Saudi Arabia. Saudi Med J 2024; 45:840-847. [PMID: 39074884 PMCID: PMC11288499 DOI: 10.15537/smj.2024.45.8.20240279] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2024] [Accepted: 07/04/2024] [Indexed: 07/31/2024] Open
Abstract
OBJECTIVES To investigate the incidence rate, clinical characteristics across different age groups, antimicrobial susceptibility, and outcomes of Elizabethkingia meningoseptica (E. meningoseptica) infections. METHODS A retrospective analysis was carried out to include 66 cases with confirmed E. meningoseptica cultures from sterile samples between January 2014 and June 2022 at King Faisal Specialist Hospital and Research Centre in Riyadh, Saudi Arabia. RESULTS A total of 66 cases were identified, with an incidence rate of 0.3 per 1000 admissions. Most cases were hospital-acquired (80.3%), primarily in critical care areas. All patients had underlying diseases, with respiratory (40.9%) and cardiovascular (39.4%) diseases being the most common. Minocycline showed the highest susceptibility (96.0%), followed by trimethoprim/sulfamethoxazole (77.0%), whereas tobramycin and colistin were fully resistant. The in-hospital mortality rate was 34.8%, whereas the 28-day mortality rate was 22.7%. Clinical characteristics across age groups showed a higher prevalence of cardiovascular disease in pediatrics than in adults, whereas exposure to mechanical ventilation, immunosuppressive therapy, previous infection, anemia, and in-hospital mortality were reported more frequently in adults (p<0.05). CONCLUSION Our study provides valuable insights into E. meningoseptica infection in Saudi Arabia, emphasizing the importance of robust infection control measures. Incidence and mortality rates align with global trends. Variations in clinical characteristics across age groups highlight the importance of tailored treatments based on patient demographics and underlying comorbidities.

Abstract
PURPOSE OF REVIEW This article aims to review the epidemiology of nonfermenting Gram-negative bacilli (NFGNB) based on recent literature reports, particularly, of the less common, but with emerging clinical significance species. RECENT FINDINGS The reported frequency of multidrug-resistant Acinetobacter baumannii and Pseudomonas aeruginosa is increasing, with very significant variability, however, between different countries. Apart from the major NFGNB, that is, A. baumannii and P. aeruginosa, already recognized as of critical importance healthcare risks, several other NFGNB genera have been increasingly associated with diverse severe infections, such as Stenotrophomonas maltophilia, Burkholderia spp., Elizabethkingia spp., Chryseobacterium spp., Achromobacter spp., Alcaligenes spp., Sphingomonas spp., Shewanella spp. and Ralstonia spp., among others. SUMMARY The exploration of the epidemiology, as well as the pathogenic potential of the of the less frequent, but emerging and increasingly reported NFGNB, is crucial, not only for immunocompromised patients, but also for critically ill patients without overt immunosuppression. As we are heading fast towards a postantibiotic era, such information would contribute to the optimal antimicrobial management, that is, providing prompt, appropriate antimicrobial coverage when needed and, at the same time, avoiding overuse and/or inappropriate use of antimicrobial therapy. Also, it would help to better understand their transmission dynamics and to develop effective prevention strategies.

Microbiological Characterization and Clinical Facets of Elizabethkingia Bloodstream Infections in a Tertiary Care Hospital of Eastern India. Infect Drug Resist 2023; 16:3257-3267. [PMID: 37249959 PMCID: PMC10225145 DOI: 10.2147/idr.s409121] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2023] [Accepted: 05/17/2023] [Indexed: 05/31/2023] Open
Abstract
Purpose Elizabethkingia is an emerging non-fermenting Gram-negative bacillus (NFGNB) causing bloodstream infections (BSI) associated with high mortality. It demonstrates a unique antimicrobial profile in showing susceptibility to antimicrobials effective against Gram-positive bacteria. This study was undertaken to determine the overall frequency of Elizabethkingia BSI, associated risk factors, microbiological susceptibility, and clonal relationship of Elizabethkingia isolates using Enterobacterial Repetitive Intergenic Consensus Polymerase Chain Reaction (ERIC-PCR). Patients and Methods Elizabethkingia isolates obtained from the blood culture of admitted patients (August 2020-December 2021) were identified by the VITEK 2 system and subjected to an antimicrobial susceptibility test by standard procedures. Demographics, co-morbidities, risk factors for survival, and outcome were summarized and analyzed by Chi-square test, Kaplan-Meier curve, and Cox regression. Clonal relatedness between Elizabethkingia isolates was analyzed using ERIC‑PCR fingerprinting with the "PAST: Paleontological statistics software package". Results Of 13,747 blood samples received during the study period, 13.59% were culture positive, and 14.60% were NFGNBs. The frequency of Elizabethkingia spp. among all NFGNBs in BSI was 29.30%, and the overall prevalence in BSI was 4.21%. In patients with Elizabethkingia BSI, Foley's catheter was present in 81.25% of the cases. 100% susceptibility was observed to linezolid, followed by vancomycin (98.75%) and chloramphenicol (89.5%). The 30-day mortality rate in the patients of Elizabethkingia BSI was 26.25%. The Presence of COVID-19, pneumonia, diabetes mellitus (DM), mechanical ventilation (MV), and prior antibiotics were significantly different (p<0.05) between the survival and death groups. ERIC-PCR profile dendrogram of Elizabethkingia isolates showed ten major clusters indicating high genetic diversity. Conclusion Elizabethkingia was responsible for one-third of NFGNB BSI in a single-center study, with approximately 26% of 30-day all-cause mortality. Most isolates were susceptible to linezolid, vancomycin, and chloramphenicol. COVID-19 was the most significant risk factor associated with mortality. ERIC-PCR of Elizabethkingia isolates exhibited high genetic diversity.
