BackgroundThe use of antibiotic agents in the treatment of infectious diseases has greatly contributed to the decrease in morbidity and mortality, but these great advances in treatment are being undermined by the rapidly increasing antimicrobial resistant organisms. Extended-spectrum beta-lactamases are enzymes hydrolyzing the beta lactam antibiotics, including third generation cephalosporins and monobactams but not cephamycins and carbapenems. They pose a serious global health threat and have become a challenge for health care providers. The aim of this research was to assess the prevalence of extended-spectrum beta-lactamase producing Escherichia coli in University of Nigeria Teaching Hospital Ituku-Ozalla Enugu and to detect the risk factors for acquisition of the resistant organism. To proffer advice on antibiotic stewardship in clinical practice and public health interventions, to curb the spread of the resistant organisms in the hospital.ResultsOut of the 200 E. coli isolates, 70 (35.00%) were confirmed positive for extended-spectrum beta-lactamase production. Fifty-three (75.7%) were from hospital acquired infections. All the isolates were resistant to ampicillin, tetracycline and chloramphenicol while 68 (97.14%) of the 70 isolates were susceptible to imipenem. BlaTEM, blaSHV and blaTEM were detected in 66 (94%) of the 70 isolates. The ESBL bla genes detected were blaCTX-M (n = 26; 37.14%), blaTEM (n = 7; 10.00%), blaSHV (n = 2; 2.86%), blaCTX-M/TEM (n = 7; 10.0%), blaCTX-M/SHV (n = 14; 20.0%) and blaCTX-M/TEM/SHV (n = 10; 14.29%). The three bla genes were not detected in 4 (5.71%) of the isolates. Recent surgery, previous antibiotic and intensive care unit admission were the associated risk factors to infections caused by extended-spectrum beta-lactamase producing E. coli.ConclusionThere is a high rate of infections caused by extended-spectrum beta-lactamase producing E. coli. Recent surgery, previous antibiotic and intensive care unit admission were associated risk factors.

Background: Antimicrobial resistance (AMR) is a major clinical challenge globally. It is mainly a consequence of inappropriate prescribing and use of antibiotics. Antimicrobial stewardship (AMS) ensures that antibiotics are prescribed and used appropriately. This study assessed AMS practice in selected Nigerian hospitals.Methodology: This was a cross sectional survey of 20 Federal, State and Private tertiary hospitals randomly selected from the six geopolitical zones of Nigeria. Using an adapted WHO tool on AMS, data were collected from each hospital as regard the existence of AMS committee, Accountability and Responsibility, AMS actions, Education and Training, Monitoring and Evaluation, Infection Prevention and Control (IPC) practice, facilities to support AMS, and challenges to AMS implementation. Gaps and challenges to the implementation of the AMS among the hospitals were identified.Results: Only 6 (30%) of the 20 hospitals had AMS committees while 2 (10%) had any evidence of leadership commitment to AMS. All the hospitals had laboratory facilities to support culture and sensitivity testing. There were no regular AMS-related education or training, monitoring, evaluation or reporting activities in the hospitals, except in 7 (25%) that had participated in the global point prevalence survey (Global-PPS) of antimicrobial use and resistance being hosted by the University of Antwerp, Belgium. Challenges impeding AMS activities included lack of human and financial resources, prescribers’ opposition, lack of awareness and absence of AMS committees. Most of the gaps and challenges bordered on seeming lack of knowledge and inadequate communication among prescribers and other stakeholders.Conclusion: There is need for intense education and training activities for prescribers and other stakeholders, including but not limited to hospital administrators.

C'estprincipalement une conséquence d'une prescription et d'une utilisation inappropriées d'antibiotiques. La gestion des antimicrobiens (AMS) garantit que les antibiotiques sont prescrits et utilisés de manière appropriée. Cette étude a évalué la pratique de l'AMS dans certains hôpitaux Nigérians. Méthodologie: Il s'agissait d'une enquête transversale de 20 hôpitaux tertiaires fédéraux, d'État et privéssélectionnés au hasard dans les six zones géopolitiques du Nigéria. À l'aide d'un outil OMS adapté sur l'AMS, des données ont été collectées auprès de chaque hôpital en ce qui concerne l'existence d'un comité AMS, la responsabilité et la responsabilité, les actions AMS, l'éducation et la formation, le suivi et l'évaluation, la  pratique de prévention et de contrôle des infections (IPC), les installations pour soutenir l'AMS. et les défis de la mise en œuvre de l'AMS. Les lacunes et les défis liés à la mise en œuvre de l'AMS parmi les hôpitaux ont été identifiés. Résultats: Seuls 6 (30%) des 20 hôpitaux avaient des comités AMS tandis que 2 (10%) avaient des preuves d'engagement du leadership envers l'AMS. Tous les hôpitaux disposaient d'installations de laboratoire pour soutenir la culture et les tests de sensibilité. Il n'y avait pas d'activités régulières d'éducation ou de formation, de suivi, d'évaluation ou de rapportage liées à la MGS dans les hôpitaux, sauf dans 7 (25%) qui avaient participé à l'enquête mondiale sur la prévalence ponctuelle (Global-PPS) de l'utilisation et de la résistance aux  antimicrobiens organisée par l'Université d'Anvers, Belgique. Les défis entravant les activités de l'AMS  comprenaient le manque de ressources humaines et financières, l'opposition des prescripteurs, le manque de sensibilisation et l'absence de comités AMS. La plupart des lacunes et des défis se limitaient à un manque apparent de connaissances et à une communication inadéquate entre les prescripteurs et les autres intervenants.Conclusion: Des activités d'éducation et de formation intensives sont nécessaires pour les prescripteurs et autres intervenants, y compris, mais sans s'y limiter, les administrateurs d'hôpitaux.

Background: Nigeria joined the global community in monitoring antimicrobial prescribing practices since 2015. Results of individual hospital Global Point Prevalence Survey (Global-PPS) have stimulated efforts at instituting hospital-based antimicrobial stewardship (AMS) programmes. We report the trends of antimicrobial prescribing rates and quality indicators for 3 surveillance periods; 2015, 2017 and 2018.Methodology: The web-based Global-PPS for surveillance of antimicrobial use in hospitals (www.globalpps.com) was completed by each participating hospital site for all inpatients receiving antimicrobials on a selected day in 2015, 2017 and 2018. Data included details on antimicrobial agents, reasons and indications for treatment and a set of quality prescribing indicators. Data were validated by the web-based data management system of University of Antwerp, exported into Microsoft Excel and analyzed with EPI INFO version 7.2.Results: Thirteen hospitals participated in the survey involving a total of 5,174 inpatients. Mean weighted overall antimicrobial prescribing prevalence was 70.7% which declined over the years from 71.7% in 2015 to 59.1% in 2018 (p<0.001). The rate of documentation of date for post prescription review improved from 27.9% in 2015 to 48.5% in 2018 (p<0.001) while the rates of targeted treatment declined from 12.0% in 2015 to 5.2% in 2018 (p<0.001). There was no significant change in the choice of parenteral drug administration (64.5% in 2015, 65.1% in 2017 and 62.6% in 2018; p=0.6803), and but there was significant increase in documentation of reasons for prescription in case notes (62.2% in 2015, 74.5% in 2017, and 70.9% in 2018; p=0.008). Overall, the main indications for therapeutic prescribing were skin and soft tissue infections (20.8%), sepsis (15.9%) and pneumonia (11.6%). The top three antibiotics for therapeutic use were ceftriaxone (18.2%), metronidazole (15.3%) and ciprofloxacin (10.4%).Conclusions: The survey showed reduction in the overall antimicrobial prescribing rate especially in hospitals that had introduced AMS programmes. Among the quality prescribing indicators, documentation of post prescription review date showed improvement. The Global-PPS serves as a cost effective, flexible and userfriendly tool in instituting AMS programmes in hospitals.

Background: Neonates admitted into neonatal intensive care unit (NICU) are at high risk of acquiring infections due to the immaturity of their immune systems and the barrage of intensive medical care. Multiple drug resistant organisms are mostly implicated in causing these infections, usually acquired through contaminated environment. This research was designed to assess the environmental contamination with multi-drug resistant organisms in neonatal intensive care unit. Methods: Environmental samples were collected from all the equipment in each of the 3 rooms in neonatal intensive care unit and cultured on 5% sheep blood agar, chocolate agar and MacConkey agar plates. The isolates were identified with standard biochemical tests. Antibiotic susceptibility profile was done using modified Kirby Bauer disc diffusion method and interpreted according to the guidelines by Clinical and Laboratory Standard Institute. Methicillin resistant Staphylococcus aureus was detected using cefoxitin disc while extended spectrum beta-lactamase (ESBL) producers were confirmed with ESBL chromogenic agar. Results: Out of 36 samples collected from different sites in the 3 rooms, 19(53%) yielded bacterial growth. A total of 28 (78%) bacterial isolates were detected, with majority 25(89%) isolated from room 1. Staphylococcus aureus 15(42%) was the predominant isolate followed by Klebsiella pneumoniae 5(14%) and non-Candida albicans spp 3(8%). Most of Staphylococcus aureus isolates were from samples collected from incubators. Out of 15 Staphylococcus aureus isolated, 11 (73%) were MRSA. Among the Gram negatives, all 5(100%) Klebsiella pneumonioae and 3(60) Acinetobacter species were positive for extended spectrum beta-lactamase production. All the isolates were resistant to 3 or more classes of antibiotics. Imipenem and linezolid were the most sensitive antibiotics to the isolated organisms. Conclusion: High degree of contamination of the environment in NICU with multi drug resistant bacteria is worrisome because of the serious threat it poses. This calls for immediate holistic interventional measures. Strict Compliance with infection prevention and control measures. Additionally, there should be regular antimicrobial resistance surveillance in NICU.
