E.3 | Principal inclusion criteria |
- Male and female patients aged >/=18 years. - Small intestinal bacterial overgrowth diagnosed based on positive hydrogen breath test (GBT or LBT) as described in The North American Consensus within 2 weeks prior to study entry. - Patients reporting recurrent bloating or feeling of abdominal distension, defined as recurrent feeling of bloating or visible distension at least 3 days/month in the last month. - Patients presenting abnormal stool frequency (abnormal is defined as >3 bowel movements/day and <3 bowel movements/week) and/or abnormal stool form (lumpy/hard or loose/watery stool) as per the Bristol-Stool scale. |
- Pazienti maschi e femmine di età >/=18 anni - Diagnosi di aumentata crescita batterica a livello dell’intestino tenue formulata in base alla positività del test del respiro (test del respiro all’idrogeno dopo assunzione di glucosio [glucose hydrogen breath test, GBT] o test del respiro all’idrogeno dopo assunzione di lattulosio [lactulose hydrogen breath test, LBT]) come descritto nel Documento di consenso nordamericano entro 2 settimane prima dell’ingresso nello studio. - Pazienti che segnalano gonfiore ricorrente o sensazione di distensione addominale, definiti come sensazione ricorrente di gonfiore o distensione visibile almeno 3 giorni/mese nel corso dell’ultimo mese. - Pazienti che presentano anomalie nella frequenza di evacuazione (per frequenza anomala si intendono >3 evacuazioni/giorno o <3 evacuazioni/settimana) e/o nella tipologia delle feci (feci irregolari/dure o molli/acquose) secondo la Scala delle feci di Bristol. |
