Antimicrobial resistance and ESBL production in uropathogenic Escherichia coli: a systematic review and meta-analysis in Ethiopia

Background

Antimicrobial resistance (AMR) is a serious threat to global health systems. Escherichia coli is a major cause of urinary tract infections (UTIs). Understanding the AMR patterns of uropathogenic E. coli (UPEC) is crucial for effective public health interventions worldwide.

Objectives

This systematic review and meta-analysis aimed to consolidate existing research and provide a comprehensive information on AMR UPEC in Ethiopia.

Methods

We systematically searched databases such as PubMed, Web of Science, and Science Direct, along with including articles from Google Scholar. Data were extracted into Microsoft Excel and analysed using STATA 17.0. Cohen's kappa was computed to assess reviewer agreement, while the I2 statistic evaluated heterogeneity. Egger's tests were conducted to detect publication bias, and random-effects models were utilized to estimate the pooled resistance, with AMR rates for each antibiotic pooled separately.

Results

UPEC showed resistance rates, ranging from 3.64% (95% CI: -4.38% to 11.67%) for amikacin to 85.32% (95% CI: 78.6%-92.04%) for ampicillin. Highest resistance was to ampicillin (85.32%), followed by amoxicillin at 82.52% (95% CI: 74.3%-90.74%), tetracycline at 60.67% (95% CI: 51.53%-69.81%) and trimethoprim/sulfamethoxazole at 57.17% (95% CI: 49.93%-64.42%). Conversely, resistance rates were lower for amikacin at 3.64% and meropenem at 5.26% (95% CI: 2.64%-7.88%). UPEC demonstrated a pooled MDR rate of 79.17% (95% CI: 70.32%-88.01%) and a pooled ESBL production rate of 29.16% (95% CI: 22.36%-38.55%).

Conclusions

High levels of AMR were observed in UPEC strains, highlighting a critical public health issue requiring urgent action through robust antimicrobial stewardship and surveillance to preserve effective UTI treatment options.

Epidemiological characteristics of Klebsiella ozaenae infection and its antibiotic susceptibility: Experience of a tertiary care hospital in the Eastern Province of Saudi Arabia

BACKGROUND

Klebsiella ozaenae (K. ozaenae), a forgotten pathogen that normally colonizes the upper respiratory mucosa, can be associated with severe and invasive infections. The objectives of this study were to determine the frequency of isolation of K. ozaenae at the microbiology laboratory in a tertiary hospital and the scope of diseases associated with it and to characterize its antimicrobial susceptibility pattern.

MATERIALS AND METHODS

This cross-sectional study analyzed the retrospective data, from 2002 to 2021, on cases with laboratory-confirmed isolation of K. ozaenae at a tertiary care hospital. The primary outcome was to identify the scope of K. ozaenae infections and their antimicrobial susceptibility patterns. K. ozaenae isolation was done by cultivation on microbiological culture media, whereas its identification and antimicrobial susceptibility pattern were performed using either Microscan or Vitek automated systems. Data was gathered and analyzed in Excel. The percentage of resistance was calculated as the number of resistant isolates from the total isolates multiplied by 100. Similarly, the percentage of sensitivity was calculated as the number of sensitive isolates from total isolates multiplied by 100.

RESULTS

K. ozaenae was detected in 59 cases during the study period. K. ozaenae was associated with urinary tract infections (39%), nasal infections (18.6%), other respiratory tract infections including sinusitis, bronchiectasis, and pneumonia (16.9%), and wound infections (15.3%). It was also associated with invasive infections such as bacteremia (3.4%) and abscesses (3.4%). K. ozaenae showed susceptibility to multiple antibiotic classes, but was resistant to ampicillin, piperacillin, nalidixic acid, and nitrofurantoin. K. ozaenae isolates from urinary tract infections had higher antibiotic resistance percentage than isolates from other infections, particularly to amoxicillin/clavulanic acid (P = 0.007, 95% confidence interval [CI]: 1.84-375), ciprofloxacin (P < 0.0001, 95% CI: 4.6-111.2), and trimethoprim/sulfamethoxazole (P < 0.001, 95% CI: 3.1-63.6).

CONCLUSION

Our data show that K. ozaenae is a pathogen with a spectrum of diseases wider than expected and a unique antibiotic susceptibility pattern in urinary tract infections.

Prevalence, antimicrobial susceptibility profile, and associated risk factors of uropathogenic Escherichia coli among pregnant women attending Dr. Sumait Hospital Mogadishu, Somalia

Background

Uropathogenic Escherichia coli (UPEC) is a strain of E. coli commonly associated with urinary tract infections. In addition, antibiotic resistance in UPEC is one of the most significant health problems. This study was conducted to determine the prevalence, antimicrobial resistance, and factors linked to uropathogenic Escherichia coli (UPEC) in pregnant women.

Methods

This cross-sectional study was conducted within a hospital setting between August 2022 and December 2022. Using consecutive convenient sampling, the research enrolled 220 pregnant women. The urine samples obtained from these women were cultured on MacConkey and blood agar and incubated at 37°C overnight, followed by sub-culturing on Mueller Hinton media. Bacterial identification involved Gram staining and biochemical characterization (TSI, indole, citrate, methyl red, urea agar, and motility tests). Conversely, susceptibility tests were performed using the Kirby-Bauer disk diffusion method. A binary logistic regression model and analysis of odds ratios (ORs) were employed to evaluate the risk factors associated with E. coli infection, and statistical significance was attributed to p-values of ≤0.05.

Results

Out of the 220 urine samples examined, 42 (19%) exhibited a positive culture, indicating an E. coli infection in pregnant women. Our analysis revealed that income, gestational age, and history of UTIs were identified as risk factors associated with E. coli infection. Most E. coli isolates demonstrated sensitivity to amikacin (100%), nitrofurantoin (85.7%), amoxicillin/clavulanic acid, and meropenem (83.3%).

Conclusion

The prevalence of E. coli was remarkable. It could be recommended that pregnant women in antenatal care have routine culture and antimicrobial susceptibility tests to prevent transmission of resistant pathogens and complications in both pregnant mothers and the unborn baby.

Magnitude, Associated Risk Factors, and Trend Comparisons of Urinary Tract Infection among Pregnant Women and Diabetic Patients: A Systematic Review and Meta-Analysis

Urinary tract infection (UTI) remains the most common bacterial infection that affects millions of people around the world, especially pregnant women (PW) and people with diabetes mellitus (DM). This systematic review and meta-analysis was aimed at finding the pooled prevalence of UTI and its associated risk factors among PW and DM patients. Scientific articles written in English were recovered from PubMed, ScienceDirect, Web of Science, Google Scholar, Cochrane Library, Google Engine, and University Library Databases. "Prevalence," "urinary tract infection," "associated factors," "pregnant women," "diabetic patients," and "Ethiopia" were search terms used for this study. For critical appraisal, PRISMA-2009 was applied. Heterogeneity and publication bias were evaluated using Cochran's Q, inverse variance (I2), and funnel plot asymmetry tests. A random effect model was used to calculate the pooled prevalence of UTI and its associated factors among both patients, along with the parallel odds ratio (OR) and 95% confidence interval (CI). For this meta-analysis, a total of 7271 participants were included in the 25 eligible studies. The pooled prevalence of UTI in Ethiopia among both patients was 14.50% (95% CI: 13.02, 15.97), of which 14.21% (95% CI: 12.18, 16.25) and 14.75% (95% CI: 12.58, 16.92) were cases of DM and PW, respectively. According to the subgroup analysis, the highest prevalence was observed in the Oromia region (19.84%) and in studies conducted from 2018 to 2022 (14.68%). Being female (AOR: 0.88, and 95% CI: 0.11, 1.65, P = 0.01) and having an income level ≤ 500ETB (AOR: 4.46, and 95% CI: -1.19, 10.12, P = 0.03) were risk factors significantly associated with UTI among patients with DM and PW, respectively. Furthermore, a history of catheterization (AOR = 5.58 and 95% CI: 1.35, 9.81, P < 0.01), urinary tract infection (AOR: 3.52, and 95% CI: 1.96, 5.08, P < 0.01), and symptomatic patients (AOR: 2.32, and 95% CI: 0.57, 4.06, P < 0.01) were significantly associated with UTI in both patients. Early diagnosis and appropriate medication are necessary for the treatment of UTI in patients with DM and PW.

Prevalence and antimicrobial susceptibility pattern of urinary tract infection among pregnant women attending Hargeisa Group Hospital, Hargeisa, Somaliland

The aim of this study was to determine the prevalence, antimicrobial susceptibility pattern and associated factors of urinary tract infection (UTI) among pregnant women attending Hargeisa Group Hospital (HGH), Hargeisa, Somaliland. A cross-sectional study was conducted at HGH, Hargeisa, Somaliland and participants were selected by systematic random sampling technique. Clean catch midstream urine samples were collected from 422 participants and cultured and antimicrobial susceptibility pattern was determined for the isolates. Univariable and multivariable logistic regression analyses were utilized to identify the independent risk factors for UTI. The prevalence of UTI was 16.4% (95% CI 13.3-19.9). The predominant bacteria isolate was E. coli (43.5%) followed by Coagulase negative staphylococcus (CoNS) 11(16%), S. aureus 9(13%), K. pneumonia 6(8.7%), Pseudomonas aeruginosa 5(7.2%), Proteus mirabilis 4(5.8%), Citrobacter spp 3(4.4%) and M. morganii 1(1.5%) Gram negative bacilli were resistant to ampicillin (96%) and tetracycline (71.4%) and Gram-positive cocci were also resistant to ampicillin (90%), tetracycline (55%). Multidrug resistance was observed in 85.5% of bacterial isolated. No formal education participants, previous history of catheterization and previous history of UTI had 3.18, 3.22 and 3.73 times respectively more likely to develop UTI than their counterparts. Culture and susceptibility test is vital for appropriate management of UTI in the study area.

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.
