Sawadpanich K, et al. - Between July 2015 and January 2016, authors investigated 89 systemic sclerosis (SSc) candidates to estimate the prevalence and correlated factors of small intestinal bacterial overgrowth (SIBO) in such patients. All the individuals experienced the glucose H₂/CH₄ breath test. They observed 12 candidates positive for this test with a SIBO prevalence of 13.5%. A significant association was observed between duration of disease >5 years and SIBO. They obtained an uncommon prevalence of SIBO (using the glucose H₂/CH₄ breath test) among Thai SSc cases.
