Microbial agents in urinary tract infections in premenopausal and menopausal women of the vinces and urdaneta counties in los rios province

Abstract:

Introduction: Urinary tract infections can be asymptomatic processes or can even cause a pyelonephritis and septic shock. These infections are more prevalent in women due to anatomic, genetic and hormonal factors. These hormonal factors are of special interest in premenopausal and menopausal women. Materials and methods: A retrospective study was performed in 350 women that went to the health centres of the Vinces and Urdaneta counties in Los Ríos province. All patients diagnosed with urinary tract infection were included, a urine culture was performed in order to obtain microbiological diagnoses. Data regarding names, race, and socioeconomic status were included as well as any pathological history of importance. The statistical analysis were performed with the SPSS program, v. 19. Results: 70.9% of the studied population had menopause while the remaining 29.1% were premenopausal. The most prevalent pathological history was that of diabetes mellitus (20%), followed by urinary incontinence (8.6%). Cystitis was the most common urinary infection (87.1%). The most prevalent etiological agent was Escherichia coli (77.1%) followed by Staphylococcus saprophyticus (7.1%). The percentage of urinary incontinence was considerably higher in menopausal women, whilst Staphylococcus saprophyticus had higher prevalence in premenopausal women tan in menopausal women (13.7% vs 5.2%). Conclusion: Menopausal women show a high diabetes prevalence, which together with age-dependant hormonal factors, promote the development of urinary tract infections. E. coli was the most common pathogen, with a higher prevalence in menopausal women, whilst in premenopausal women; S. saprophyticus had a higher prevalence than in menopausal women. This highlights the importance of knowing etiological agents in our population according to the stage of life, especially in women that are intrinsecally more pbkp_redisposed to have these type of infections.
