[Efficacy of rifaximine in small intestinal bacterial overgrowth syndrome in patients after cholecystectomy].

ABSTRACT

AIM: To define frequency of onset of small intestinal bacterial overgrowth syndrome (SIBOGS) in patients with postcholecystectomy syndrome (PCS); to substantiate necessity of microflora correction and assess efficacy of rifaximine in the doses 800 and 1200 mg/day. MATERIAL AND METHODS: A breath hydrogen test (BHT) was made in 82 PCS patients. Rifaximine was given to 40 SIBOGS patients 20 of them received the drug in a dose 800 mg/day and 20--in a dose 1200 mg/day for 7 days. The efficacy was estimated by attenuation of the clinical symptoms and parameters of BHT. RESULTS: SIBOGS was detected in 73% of PCS patients. This was an indication for antibacterial treatment. Rifaximine in a dose 800 mg/day failed to attenuate pain and to eliminate dyspeptic syndromes in some patients, BHT in them was not normal. Administration of rifaximine in a dose 1200 mg/day normalized BHT in 90% patients and eliminated clinical symptoms in most of the patients. CONCLUSION: Rifaximine in a dose 1200 mg/day vs 800 mg/day in PCS patients with SIBOGS is more effective as it eliminates clinical symptoms and normalizes BHT.
