Abstract

Estrogen deficiency is a major contributor to the pathogenesis of urinary tract infections (UTI) in postmenopausal women. After menopause, the vaginal pH increases, lactobacilli disappear from the vaginal flora, and the vagina is predominantly colonized by Enterobacteriaceae, especially Escherichia coli. To better understand the associations between post-menopausal vaginal flora and the development of UTI, we conducted a prospective study among 87 postmenopausal women ages between 50-65 years. Vaginal samples were collected from lateral vaginal wall of women to perform a smear on a glass slide and placed on appropriate media. The smear was then stained with Gram stain. Urine samples were collected and cultured by standard bacteriologic techniques. Vaginal lactobacilli were present in 55.2%, and vaginal Enterobacteriaceae were present in 40.2% of the subjects. Heavy growth of lactobacilli was associated with a lower frequency of vaginal colonization with Enterobacteriaceae members (p<0.001), Streptococcus sp. (p<0.05) and Pseudomonas sp. (p<0.05). The most commonly isolated microorganism was E.coli. The frequency of asymptomatic bacteriuria and symptomatic UTI among postmenopausal women were found 17.5% (15/87) and 11.5% (10/87), respectively. As a result, Enterobacteriaceae colonization of the vagina in postmenopausal women increases the prevalence of asymptomatic bacteriuria and symptomatic UTI (p<0.01and p<0.05, respectively).

Özet

Rektal floradan köken alan Enterobacteriaceae üyelerinin kadınların üretra ve vajen mukozasına kolonizasyonu, üriner sistem enfeksiyonlarının (ÜSE) önemli bir nedenidir. Bu konu ile ilgili olarak menapoz sonrası kadınlarda östrojen eksikliğine bağlı olarak lokal pH'da artma meydana geldiği, böylelikle vajinal mikrofloranın değiştiği, asidik ortam yaratan laktobasillerin kaybolarak Escherichia coli başta olmak üzere Enterobacteriaceae üyelerinin kolonizasyonunun arttığı bildirilmektedir. Bu prospektif çalışmada, yaşları 50-65 arasında değişen 87 menopoz sonrası dönemdeki kadından aynı anda vajinal sürüntü ve idrar örnekleri alınarak vajinal kolonizasyon ile ÜSE arasındaki ilişkinin araştırılması amaçlanmıştır. Vajinal örneklerden direk preparatlar hazırlanarak Gram yöntemiyle boyanmış ve tüm örnekler uygun besiyerlerine ekilmiştir. Vajinal örneklerin %55,2'sinden Laktobacillus türleri, %40.2'sinden ise Enterobacteriaceae ailesine ait bakteriler izole edilmiştir. Vajinal floralarında Lactobacillus sp. izole edilmeyen kadınlarda (Laktobasil negatif grup), izole edilenlere (Laktobasil pozitif grup) göre, Enterobacteriaceae üyeleri (p<0.001), Streptococcus sp. (p<0.05) ve Pseudomonas sp. (p<0.05) ile kolonizasyonun daha fazla olduğu tespit edilmiştir. En sık izole edilen mikroorganizmanın E.coli (%48.6) olduğu, kadınların 15'inde (%17.2) asemptomatik bakteriüri, 10'unda (%11.5) ise ÜSE'nun klinik bulguları ve idrar mikroskobisinde piyürinin mevcudiyeti izlenmiştir. Sonuç olarak, vajinal Enterobacteriaceae kolonizasyonu olan kadınlarda asemptomatik bakteriüri ve ÜSE görülme oranları, olmayanlardan anlamlı derecede yüksek olarak tespit edilmiştir (p<0.01 ve p<0.05).
