Abstract

BACKGROUND: Urinary tract infections (UTI) and asymptomatic bacteriuria (AB) during pregnancy can result in considerable maternal and foetal adverse outcomes. Production of extended-spectrum beta-lactamase (ESBL) is a major antibiotic resistance mechanism by Enterobacteriaceae. OBJECTIVES: To determine the global prevalence of ESBL-producing (ESBL-P) Enterobacteriaceae in symptomatic UTI/AB among pregnant/postpartum females. DATA SOURCES: A systematic review of the PubMed, Embase, Scopus, WOS (Web of Science), ProQuest and the grey literature was conducted. STUDY SELECTION AND DATA EXTRACTION: Studies that reported the frequency of ESBL-P Enterobacteriaceae in pregnant/postpartum women with UTI and/or AB were eligible. First, the titles and abstracts of the retrieved articles were reviewed. Then, the full texts of the remained articles were reviewed. SYNTHESIS: In order to estimate the pooled prevalence and the 95% confidence interval (95% CI), meta-analysis was performed using the random-effects model. RESULTS: = 98.8%. The estimated prevalence (95% CI) rates were 45% (22, 67%) in Africa, 33% (22, 44%) in India, 15% (6, 24%) in other Asian countries, 5% (2, 8%) in Europe, 4% (1, 11%) in South America and 3% (1, 5%) in North America (P < .001). This estimate was 21% (95% CI 11, 31%) in patients with symptomatic UTI and it was 28% (95% CI 15, 41%) in patients with AB (P = .40). CONCLUSIONS: The prevalence of ESBL-P Enterobacteriaceae among pregnant women with UTI/AB was significant and geographic region was a major source for heterogeneity. The findings could be taken into account by healthcare providers and programmers in the management and antibiotic selection of UTI/AB during pregnancy, especially in high prevalence areas.

TL;DR

This systematic review and meta-analysis estimated that 25% of pregnant/postpartum women with urinary tract infection or asymptomatic bacteriuria had ESBL-producing Enterobacteriaceae in urine culture. Prevalence varied widely by region, with the highest rates in Africa and India and the lowest in North America and Europe.

Key findings

  • Across 23 included studies reporting 20,033 Enterobacteriaceae strains, the pooled prevalence of ESBL-producing Enterobacteriaceae was 25% (95% CI 18–32%); heterogeneity was high (I² = 98.8%).
  • Regional pooled prevalence was 45% (22–67%) in Africa, 33% (22–44%) in India, 15% (6–24%) in other Asian countries, 5% (2–8%) in Europe, 4% (1–11%) in South America, and 3% (1–5%) in North America.
  • Prevalence was 21% (95% CI 11–31%) in symptomatic UTI and 28% (95% CI 15–41%) in asymptomatic bacteriuria; the difference was not statistically significant (P = .40).
  • Among studies reporting specific organisms, E coli had a pooled prevalence of 61% (47–74%) and K pneumoniae 40% (22–57%); in the separate E coli-only subset of 10 studies, pooled ESBL-positive E coli prevalence was 17% (95% CI 9–24%).

Methods

  • Systematic review and meta-analysis following PRISMA 2009, searching PubMed, Embase, Scopus, Web of Science, ProQuest, LILACS, Google Scholar, ECCMID, and ICID from October 2008 to October 2018 without language restriction.
  • Eligible studies reported urine-culture prevalence of ESBL-producing Enterobacteriaceae in pregnant/postpartum women with symptomatic UTI and/or asymptomatic bacteriuria; rectovaginal colonization studies and specific populations were excluded.
  • From 7,489 records, 31 records met inclusion criteria, yielding 33 studies for quantitative analysis: 23 Enterobacteriaceae studies and 10 E coli-only studies; random-effects meta-analysis with subgroup analysis by geographic region, sensitivity analysis, and Begg/Egger tests for reporting bias.

Limitations

  • The paper states that infection type was not recognizable in five studies, no studies were found from Oceania, and only two North American and one South American study were included; risk factors, antibiotics administered, and treatment outcomes were generally not reported.
  • Evident from the text: heterogeneity was very high overall (I² = 98.8%) and in the E coli-only subset (I² = 88.27%), and several included studies were low quality (6 of 23 in the Enterobacteriaceae group; 7 of 10 in the E coli-only group), which may limit confidence in pooled estimates.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-18.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-18.

Statistics and arithmetic are recomputed, not judged.
