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.

Background and Objectives: Catheter-associated urinary tract infections (CAUTIs) caused by extended-spectrum beta-lactamase (ESBL)-producing and carbapenem-resistant Enterobacterales (CRE) significantly contribute to global rates of UTI. This study aimed to compare the prevalence and trends of ESBL-producing Enterobacterales and CRE in patients with CAUTIs and non-CAUTIs. Materials and Methods: A retrospective review of 4262 UTI-positive urine cultures was conducted at King Fahad Hospital of the University, Al Khobar, Saudi Arabia (January 2022–November 2023). Demographic, clinical, and microbiological data were obtained from hospital records. Antimicrobial susceptibility was tested using the Vitek^® System; ESBL and CRE were identified using Ezy MIC™ strips and Xpert^® Carba-R assay, respectively. Results: ESBL-producing Enterobacterales accounted for 11.3% of cases; CRE comprised 1.8%. ESBL was significantly more prevalent in non-catheterized patients and those in emergency care. CRE was significantly associated with catheterized patients and inpatient settings. Escherichia coli and Klebsiella pneumoniae were the predominant ESBL-producing and CRE isolates, respectively. bla-OXA-48 was the most frequently detected carbapenemase gene (66.7%). ESBL was prevalent in younger, non-catheterized females, suggesting increasing community transmission. Conversely, CRE were primarily observed in older, catheterized inpatients, emphasizing the role of invasive devices in resistance spread. Conclusions: These findings highlight the importance of targeted infection control and early catheter removal to mitigate resistance trends.

Background and Objectives: Candiduria is a common health problem especially among hospitalized patients. In the era of rising azole resistance, evidence from Saudi Arabia remains limited concerning Candida species. This study aimed to assess the prevalence and risk factors of Candida isolated from urine culture and to explore species distribution in relation to clinical characteristics. Materials and Methods: We retrospectively reviewed 188353 urine samples from 2013 to 2023. Using medical records, data on age, gender, hospitalization status, and urine sample type were collected. Identification of Candida species was performed by VITEK Mass Spectrometry (bioMerieux Inc.). Binary logistic regression analysis was used to identify predictors of candiduria. A p value below 0.05 at a 95% CI was considered statistically significant. Results: A total of 1667 urine samples with significant Candida growth were reported. It accounted for 0.88% of all organisms grown from urine culture and 30% of Candida grown from various body sites. Candida albicans was the most frequently identified species (n = 920, 55.2%), followed by C. tropicalis (n = 374, 22.4%), C. krusei (n = 80, 4.8%), C. glabrata (n = 78, 4.7%), and C. parapsilosis (n = 41, 2.5%). However, the rate was not stable throughout the years, and non-albicans Candida (NAC) was often the most prevalent. Female gender was the strongest predictor of candiduria (OR and AOR 1.81, 95% CI 1.46–2.25), whereas significantly lower odds were seen in elderly patients and in random urine specimens. The species distribution of NAC did not seem to change with age, gender, type of specimen, or hospitalization status. Conclusions: Among all Candida spp. isolated in the lab, 30 out of every 100 originated from urine culture, with a significant risk associated with females. The increasing prevalence of emerging Candida species in tertiary care settings can provide clinicians with valuable insights for the diagnosis and management of Candida UTI.
