A recent study demonstrated that 46% of patients with Rosacea (including 4 with treatment resistant ocular rosacea) had Small Intestinal Bacterial Overgrowth (SIBO) as opposed to 23% in the general population. This condition was diagnosed by a simple breath test (Lactulose Breath test).
Rosacea patients were treated with an antibiotic (Rifaximin) which remains in the intestine and is not absorbed.
Complete resolution of symptoms occurred in all 4 patients with ocular rosacea as well 78% patients with facial rosacea.
The authors recommend a larger study of facial and ocular rosacea, chcking for SIBO and its treatment with Rifaximin, be done in a Dermatology Clinic.
