Bacterial profile and antimicrobial resistance patterns of common bacteria among pregnant women with bacteriuria in Ethiopia: a systematic review and meta-analysis

Background Globally, antimicrobial resistance (AMR) restricted the armamentarium of the health care providers against infectious diseases, mainly due to the emergence of multidrug resistant. This review is aimed at providing contemporary bacterial profile and antimicrobial resistance pattern among pregnant women with significant bacteriuria. Methods Electronic biomedical databases and indexing services such as PubMed/MEDLINE, Web of Science, EMBASE and Google Scholar were searched. Original records of research articles, available online from 2008 to 2021, addressing the prevalence of significant bacteriuria and AMR pattern among pregnant women and written in English were identified and screened. The relevant data were extracted from included studies using a format prepared in Microsoft Excel and exported to STATA 14.0 software for the outcome measure analyses and subgrouping. Results The data of 5894 urine samples from 20 included studies conducted in 8 regions of the country were pooled. The overall pooled estimate of bacteriuria was 15% (95% CI 13–17%, I2 = 77.94%, p < 0.001) with substantial heterogeneity. The pooled estimate of Escherichia coli recovered from isolates of 896 urine samples was 41% (95% CI 38–45%) followed by coagulase-negative Staphylococci, 22% (95% CI 18–26%), Staphylococcus aureus, 15% (95% CI 12–18%), Staphylococcus saprophytic, 12% (95% CI 6–18%) Proteus mirabilis, 7% (95% CI 4–10%), Enterococcus species, 6% (0–12%), Pseudomonas aeruginosa, 4% (2–6%), Citrobacter species, 4% (95% CI 2–4%), Group B streptococcus, 3% (1–5%), and Enterobacter species, 2% (1–4%). Multidrug resistance proportions of E. coli, Klebsiella species, Staphylococcus aureus and Coagulase negative staphylococci, 83% (95% CI 76–91%), 78% (95% CI 66–90%), 89% (95% CI 83–96%), and 78% (95% CI 67–88%), respectively. Conclusion The result of current review revealed the occurrence of substantial bacteriuria among pregnant women in Ethiopia. Resistance among common bacteria (E. coli, Klebsiella species, Staphylococci species) causing UTIs in pregnant women is widespread to commonly used antibiotics. The high rate of drug resistance in turn warrants the need for regular epidemiological surveillance of antibiotic resistance and implementation of an efficient infection control and stewardship program.

An Update on Secondary Bacterial and Fungal Infections and Their Antimicrobial Resistance Pattern (AMR) in COVID-19 Confirmed Patients at a Tertiary Care Hospital

Introduction Since coronavirus disease 2019 (COVID-19) has limited treatment options, concern has been raised over secondary infections and antimicrobial resistance (AMR) patterns. It has been observed that patients who were infected with COVID-19 were predisposed to develop secondary infections. The purpose of the study is to ascertain the prevalence of the bacterial and fungal coinfections in COVID-19 patients, and also to assess the AMR patterns in the obtained isolates. Methods We have studied 200 clinical samples obtained from 122 COVID-19 positive patients. Pathogens were identified using Vitek 2 system. The demographic and clinical patterns were also observed. Results A total of 122 patients developed secondary infections. Patients aged more than 40 years were majorly affected (p-value < 0.0001). Respiratory samples (n = 96) were predominant. Klebsiella pneumoniae (n = 68) was the most common pathogen isolated followed by Acinetobacter baumannii (n = 54) and an overall 6% rise in the Carbapenem resistance was observed in the isolates. Conclusion To contain the secondary infections in COVID-19 patients, it is imperative to adhere to antimicrobial stewardship program and timely revise the empirical antibiotic policy.

Antimicrobial Stewardship Program: Reducing Antibiotic’s Spectrum of Activity Is not the Solution to Limit the Emergence of Multidrug-Resistant Bacteria

Overconsumption of antibiotics in hospitals has led to policy implementation, including the control of antibiotic prescriptions. The impact of these policies on the evolution of antimicrobial resistance remains uncertain. In this work, we review the possible limits of such policies and focus on the need for a more efficient approach. Establishing a causal relationship between the introduction of new antibiotics and the emergence of new resistance mechanisms is difficult. Several studies have demonstrated that many resistance mechanisms existed before the discovery of antibiotics. Overconsumption of antibiotics has worsened the phenomenon of resistance. Antibiotics are responsible for intestinal dysbiosis, which is suspected of being the source of bacterial resistance. The complexity of the intestinal microbiota composition, the impact of the pharmacokinetic properties of antibiotics, and the multiplicity of other factors involved in the acquisition and emergence of multidrug-resistant organisms, lead us to think that de-escalation, in the absence of studies proving its effectiveness, is not the solution to limiting the spread of multidrug-resistant organisms. More studies are needed to clarify the ecological risk caused by different antibiotic classes. In the meantime, we need to concentrate our efforts on limiting antibiotic prescriptions to patients who really need it, and work on reducing the duration of these treatments.

Antibiotic stewardship for nurses: Using e-learning modules to bridge the education gap

Objective: The Centers for Disease Control and Prevention has called for an interdisciplinary approach to antibiotic stewardship implementation that includes front-line nurses. The literature to date has identified key factors preventing uptake by nurses: lack of education, poor communication among providers, and unit culture. Three e-learning modules were developed to address the nurses’ education regarding the roles nurses play in antibiotic stewardship, antibiotic resistance, allergy assessment, medication side effects and interactions, pharmacokinetics–pharmacodynamics, culture interpretation, specimen collection, and the antibiogram. A survey was used to assess whether nurses felt more prepared to participate after finishing the modules. Setting: Front-line staff nurses in acute care were assigned e-learning modules as part of their pharmacy’s introduction of an antibiotic stewardship program for nurses. Methods: Nurses viewed the modules and completed a survey designed to rank their usefulness and to assess their attitudes. Results: Overall, 81% of nurses felt that they should be part of the antibiotic stewardship team. After completing the modules, 72% felt more empowered to participate in stewardship discussions and an additional 23% requested more education. Also, 97% felt that the information they learned could be utilized in everyday work regardless of the new program. The most cited barriers to stewardship activities were lack of education (45%) and hospital and/or unit culture (13%). Conclusion: Education and culture need to be addressed to overcome the barriers to nurses’ involvement in antimicrobial stewardship. E-learning can provide a simple and effective first step to educate nurses, with minimal time investment.

Retrospective analysis of adverse effects associated with pyrethrins-containing products

The Pyrethrins Stewardship Program (PSP) was established to better understand adverse effects following exposure to pyrethrins-containing insecticide products. Running from April 2010 through December 2016, symptomatic dermal and inhalation exposures were entered into Phase I of the PSP and analyzed for exposure details and nature of the effects reported. Phase II consisted of an in-depth telephone interview using an enhanced questionnaire to investigate additional exposure details. Phase III scored the association between exposure and reported effects. Based on the data collected and analyzed, we conclude that: (1) Both in absolute number and relative to the wide distribution and use by consumers, adverse respiratory or dermal events after product exposure were rare; (2) Most outcomes for the reported events involving either dermal or respiratory effects were of minor severity and self-limiting; (3) None of the data collected and analyzed indicate that pyrethrins-containing products, including those formulated with synthetic pyrethroids and/or synergists, pose a significant risk of serious dermal or respiratory reactions even in cases where the exposed individual reported having allergies or asthma; (4) No additional label warnings or other mitigation techniques are warranted with pyrethrins-containing products formulated with or without synthetic pyrethroids and/or synergists.

Introducing antimicrobial stewardship to the outpatient clinics of a suburban academic health system

Objective: To establish an antimicrobial stewardship program in the outpatient setting. Design: Prescribers of antimicrobials were asked to complete a survey regarding antimicrobial stewardship. We also monitored their compliance with appropriate prescribing practices, which were shared in monthly quality improvement reports. Setting: The study was performed at Loyola University Health System, an academic teaching healthcare system in a metropolitan suburban environment. Participants: Prescribers of antimicrobials across 19 primary care and 3 immediate- and urgent-care clinics. Methods: The voluntary survey was developed using SurveyMonkeyand was distributed via e-mail. Data were collected anonymously. Rates of compliance with appropriate prescribing practices were abstracted from electronic health records and assessed by 3 metrics: (1) avoidance of antibiotics in adult acute bronchitis and appropriate antibiotic treatment in (2) patients tested for pharyngitis and (3) children with upper respiratory tract infections. Results: Prescribers were highly knowledgeable about what constitutes appropriate prescribing; verified compliance rates were highly concordant with self-reported rates. Nearly all prescribers were concerned about resistance, but fewer than half believed antibiotics were overprescribed in their office. Among respondents, 74% reported intense pressure from patients to prescribe antimicrobials inappropriately. Immediate- and urgent-care prescribers had higher rates of compliance than primary-care prescribers, and the latter group responded well to monthly reports and online educational resources. Conclusions: Intense pressure from patients to prescribe antimicrobials when they are not indicated leads to overprescribing, an effect compounded by the importance of patient satisfaction scores. Compliance reporting improved the number of appropriate antibiotics prescribed in the primary care setting.

Occurrence and Antimicrobial Susceptibility Profiles of Streptococcus equi subsp. zooepidemicus Strains Isolated from Mares with Fertility Problems

Streptococcus equi subsp. zooepidemicus (S. zooepidemicus), is a β-hemolytic Streptococcus belonging to the Lancefield group C; it is a rare human pathogen, but in horses, it is frequently associated with endometritis. This study aimed to isolate S. zooepidemicus strains, associated with bacterial endometritis in mares, and to define their antimicrobial resistance profile. Twenty-three isolates were recovered from one hundred ninety-six equine uterine swabs (11.7%). Bacterial identification was carried out by Api 20 Strep and confirmed by matrix assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF-MS), while antimicrobial susceptibility testing was performed by disk diffusion method on Muller Hinton agar plates. The antibiotic resistance profiles of the isolates revealed a high percentage of resistance to amikacin (95.6%), ampicillin (73.9%) and tetracycline (69.6%), while ceftiofur and ceftriaxone were highly effective with 82.6% and 78.3% of the isolates inhibited, respectively. An intriguing value of resistance to penicillin (34.8%), which represents the first-choice antibiotic in equine S. zooepidemicus infections, was observed. Furthermore, a high prevalence of multidrug-resistant strains (82.6%) was recorded. Continuous surveillance of this potential zoonotic pathogen and an appropriate antimicrobial stewardship program with the promotion of correct use of antimicrobials, after a proper diagnosis, are needed to allow an effective therapy.

Comparison of the Logical Use of Parenteral Antibiotics Before and After the Implementation of the Stewardship Program

Background: Excessive use of antibiotics has led to drug resistance. As such, stewardship programs are implemented to control antibiotic use in hospitalized patients. Objectives: The present study aimed to evaluate the frequency of antibiotic use after the implementation of the stewardship program. Methods: This retrospective study was conducted on the patients admitted to Imam Reza Hospital in Kermanshah, Iran during 2017 - 2018. The required data were extracted from the pharmaceutical ward of the hospital. Data analysis was performed in SPSS version 24. Results: The median per capita numerical and Rial consumption of caspofungin and linezolid antibiotics increased after the implementation of the stewardship plan, while the consumption of imipenem, amphotericin, teicoplanin, colistin, meropenem, voriconazole, and vancomycin was observed to decrease. In addition, the median per capita of the numerical use of caspofungin and linezolid increased in the surgery ward, intensive care unit (ICU), and internal medicine ward after the implementation of the stewardship plan. On the other hand, a reduction was observed in the use of amphotericin, colistin, voriconazole, and vancomycin in only one ward. The use of meropenem and teicoplanin also increased in the surgery ward and decreased in the other wards, while the use of imipenem increased in the ICU after implementing the plan and decreased in the other wards. The median use of antibiotics was not considered significant in the internal medicine ward, surgery ward, and ICU before and after implementing the stewardship program (P > 0.05). Conclusions: According to the results, antibiotic use slightly decreased after the implementation of the stewardship program. However, an increase was also observed in antibiotic prescription in some cases, which indicated that the stewardship program was not implemented properly, and no changes occurred in antibiotics prescription.
