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.

Treatment Protocol

Protocol treatment sites will be expected to see the patient within a pre-specified window of time. The doctors at that site will apply the treatment algorithm and will make decisions about response to treatment based on the algorithm and on specific patient answers to questionnaires. The treatment protocol will only be made available to IRBs, not to any site personnel before randomization. This was derived from a survey of rheumatologists in many countries and gastroenterologists, mostly in North America, who were asked multiple questions about how they would treat and follow up patients with suspected SIBO. Successful treatment is a response on GSS of no diarrhea plus a total GSS of \< 5.

OTHER

Standard of Care

Physicians randomly assigned to standard of care will also be informed of their patients who met eligibility criteria. They will not be aware of the detailed treatment protocol but will be informed of which medications are in the protocol eg antibiotics, prokinetics etc. They will be free to contact the patients at their convenience and to treat them in any way they deem suitable, preferably using these medications but at doses and frequencies according to their own wishes.
