Abstract

Purpose: Asymptomatic bacteriuria (ASB) is the presence of significant amounts of bacteria within the urinary tract in the absence of urinary tract infection (UTI) symptoms, resulting in negative neonatal and pregnancy consequences. This study determined the prevalence, bacteriology patterns, and associated factors with ASB among pregnant women in both primary and hospital levels of care in the Eastern Province of Saudi Arabia.

Methods: This retrospective chart review study included pregnant women between 18 and 50 years who performed the screening urine culture test during their first antenatal visit between 2017 and 2021, without UTI symptoms. The collected data involved the demographic, medical, and obstetric characteristics, and urine culture results. T-tests and chi-squared tests were used for bivariate associations followed by binary logistic regression models.

Results: ASB was positive among 03.42% of the 6471 pregnant women included in the study. Logistic regression revealed that the risk of positive ASB increased in pregnant women in the first and second trimesters (OR = 2.04, 95% CI = 1.41-2.93 and OR= 1.50, 95% CI = 1.03-2.19, respectively), as well as pregnant women with a history of previous UTI (OR = 2.98, 95% CI = 2.14-4.15). The predominant organism isolates were E. coli, followed by GBS, Klebsiella pneumoniae, and Enterococcus faecalis.

Conclusion: With limited data on ASB among pregnant women in Saudi Arabia, findings from the current study could help decision-makers in the country assess the epidemiological characteristics of the condition. Further study is recommended to investigate the susceptibility patterns of commonly prescribed antibiotics with different uropathogens to guide the clinicians who deal with these cases. Additionally, a large national study across the other regions in the kingdom is suggested to calculate the prevalence of ASB in Saudi Arabia.
