Abstract

Background/aims: Measurement of lactulose excretion in urine following oral ingestion is used as a noninvasive method of assessing small intestinal permeability. The aim of this study was to determine the adult reference interval of urinary lactulose excretion following oral administration. Methods: Thirty seven volunteers (mean age 37.3 ± 15 years) with no his-tory of gastrointestinal disease were recruited as study subjects. All subjects were fasted overnight (10 hours), emptied their bladders and then drank a 50-mL solution containing 15 mL of Duphalac (10 g lactulose) and 35 mL flavoured water. Urine was collected for six hours in a bottle. Comparisons were made for 37 samples. Results: in adults, the mean urinary lactulose concentration was 0.58 ± 0.39 mmol/L. Conclusion: This study determined the adult reference range for lactulose excreted in the urine, using a sensitive quantitative assay based on hydrolysing lactulose and enzymatically assaying fructose, one of the component monosaccharides.

Özet

Amaç: Ağızdan alınan laktulozun idrarla atılımı, ince barsak geçirgenliğinin değerlendirilmesinde noninvaziv bir metod olarak kullanılmaktadır. Bu çalışmanın amacı, oral yolla verildikten sonra idrarla atılan laktulozun yetişkinler için referans aralığını belirlemektir. Yöntem: Çalışma grubu olarak, gastrointestinal hastalık öyküsü olmayan 37 gönüllü alındı (yaş ortalaması: 37.3 ± 15 yıl). Bütün denekler 10 saatlik bir açlıktan sonra sabah ilk idrarlarını attılar. Daha sonra 15 mL Duphalac (10 g laktuloz) ve 35 mL aramalı su içeren 60 mL'lik bir solüsyon içirildi. Sonraki 6 saat boyunca idrarları toplandı. 37 örnek için karşılaştırma yapıldı. Bulgular: Yetişkinlerde idrar laktuloz konsantrasyonu ortalama 0.58 ± 0.39 mmol/L olarak bulunmuştur. Sonuç: Bu çalışmada laktulozu hidrolize ederek bileşiminde bulunan monosakkaritlerden biri olan fruktozun enzimatik tayinine dayanan hassas bir kantitatif metod kullanılmış ve yetişkinlerde idrarla atılan laktuloz için referans aralığı tanımlanmıştır.
