The Small Intestine Bacterial Overgrowth Study Pilot

Plain-language summary

This is a pragmatic study in which will compare a detailed treat-to-target (T2T) treatment algorithm to standard care for SSc SIBO at multiple sites around the world. The treatment algorithm was developed from the results of a survey of SIBO treatment preferences of rheumatologists and gastroenterologists. Although the drugs in the algorithm are already used in SSc, there is no uniform way of doing this and assessing the patient response. A very standardized protocol was created with details of how to use the medications, the duration of use and the timing of different drugs. In addition, symptoms of SIBO will be dectected by having patients complete a validated screening questionnaire, the global symptomatic score (GSS), online every 3 months for the duration of the study. A score \> 5 is very strongly related to bacterial overgrowth. In other studies, about 40% of unselected patients score at this level. This same questionnaire will be used in the T2T doctors' offices to decide if response is adequate and will also be used to assess outcome in the algorithm group versus standard care group. The primary outcome is the change in symptoms based on the total GSS. Secondary outcomes will include examination of all GSS subscales. HRQoL will be assessed by the social scale of the newly developed UCLA SSc GIT 2.0 questionnaire, which has become the standard GI questionnaire in SSc trials. RN. # 00296313
