Published Studies Related to Xifaxan (Rifaximin)

[Role of rifaximin in the treatment of colonic diverticular disease]. [Article in Italian] [2012]
Diverticular disease of the colon is the fifth most important gastrointestinal disease in terms of direct and indirect healthcare costs in western countries. Although most patients with colonic diverticula remain asymptomatic for their whole life, in 20-25% of cases will develop symptoms.No definitive conclusion can be drawn regard a possible role of rifaximin for preventing diverticulitis.

Double-blind randomized controlled trial of rifaximin for persistent symptoms in patients with celiac disease. [2011.10]
BACKGROUND: Small intestinal bacterial overgrowth (SIBO) is one cause of a poor response to a gluten-free diet (GFD) and persistent symptoms in celiac disease. Rifaximin has been reported to improve symptoms in non-controlled trials. AIMS: To determine the effect of rifaximin on gastrointestinal symptoms and lactulose-hydrogen breath tests in patients with poorly responsive celiac disease... CONCLUSIONS: Rifaximin does not improve patients' reporting of gastrointestinal symptoms and hydrogen breath tests do not reliably identify who will respond to antibiotic therapy.

Rifaximin: new therapeutic indication and future directions. [2011.07]
BACKGROUND: Rifaximin is a nonabsorbable oral antibiotic that acts locally in the gastrointestinal tract with minimal systemic adverse effects. Rifaximin received new labeling for reduction in the risk of the recurrence of overt hepatic encephalopathy (HE) in patients with advanced liver disease in March of 2010. OBJECTIVE: This article reviews the pharmacology, pharmacokinetics, and pharmacodynamics of rifaximin. The efficacy and safety of rifaximin in reducing the risk of the recurrence of overt HE in patients with advanced liver disease, the new US Food and Drug Administration-approved indication, is the focus of this review. Emerging data on the use of rifaximin in irritable bowel syndrome (IBS) and Clostridium difficile infection (CDI) are also evaluated... CONCLUSIONS: Rifaximin can be an effective option for reduction in the risk of the recurrence of HE in patients with advanced liver disease. Studies suggest that rifaximin provides relief of global symptoms of diarrhea-predominant IBS and bloating. Use of rifaximin in CDI requires further study.

Rifaximin treatment for reduction of risk of overt hepatic encephalopathy recurrence. [2011.05]
Hepatic encephalopathy (HE) is a common problem in patients with chronic liver disease and is characterized by diminished mentation and neuromuscular abnormalities.It is recommended that patients with a history of recurrent acute HE should be maintained on rifaximin with or without lactulose to reduce the risk of recurrent HE and related hospitalization.

Clinical Trials Related to Xifaxan (Rifaximin)

Induction of Clinical Response Using Rifaximin in Crohn's Disease [Recruiting]
Antibiotics have been used to treat Crohn's disease symptoms with the best studied antibiotics being Cipro and Flagyl. Rifaximin is a poorly absorbed oral antibiotic that is FDA approved for travelers' diarrhea. It works by inhibiting bacterial reproduction. It is very poorly absorbed and over 97% of the drug taken orally is excreted in the feces.

The purpose of this study is to evaluate the potential benefits and safety of Rifaximin for the treatment of moderate to severe symptoms of Crohn's Disease.

Rifaximin Treatment of Papulopustular Rosacea [Not yet recruiting]
The purpose of this study is to determine the effects of rifaximin on skin symptoms in patients with rosacea by double-blinded, placebo-controlled, crossover study.

Impact of an Antibiotic (Rifaximin) on Liver Scarring in HIV-Infected Patients With Liver Disease [Recruiting]
For HIV-infected patients who have access to treatment, liver diseases are a major cause of morbidity and mortality. Hepatitis C is the most frequently encountered liver condition in this population. Both diseases allow a higher level of poisonous substances (toxins) normally produced by the bacteria present in the gut to enter the bloodstream. This leads to a chronic inflammatory state, which results in faster development of liver scars (fibrosis) and ultimately, end stage disease (cirrhosis). To prevent this from happening, the use of antibiotics has been attempted to reduce the quantity of gut flora in the hopes of lowering the amount of toxins produced. These trials have shown promising results, but the antibiotics studied had major side effects and were not designed for continuous use. Rifaximin is a non absorbable antibiotic with very few side effects. It is already used for long periods of time in cirrhotic patients to treat the effects of cirrhosis on the brain (encephalopathy). This project will try to determine if rifaximin, by reducing the level of toxins produced by the bacteria in the gut, can improve the evolution of liver fibrosis in HIV-infected patients with hepatitis C. In this pilot study, ten patients will be followed for one year. They will be included if they are starting on rifaximin, for its currently approved FDA indication (hepatic encephalopathy).

A Pilot Study of Xifaxan to Treat Patients With PSC [Recruiting]
In the current protocol, we propose the assessment of potential beneficial effects of the antibiotic Xifaxan on liver biochemistries, liver related symptoms and Mayo risk score in 15 adult and 5 pediatric patients with PSC. Adult patients will receive Xifaxan, 550 mg twice daily over a 12-week period. Pediatric patients with PSC whose weight is greater than or equal to 40 kg will receive Xifaxan, 550 mg twice daily.

Rifaximin to Prevent Recurrent HCV-Related Fibrosis After Liver Transplant [Recruiting]
The purpose of this study is to determine if the administration of a poorly-absorbable antibiotic (rifaximin) for the first three months after liver transplant will reduce the amount of fibrosis (or scarring of the liver) in liver transplant patients with recurrent hepatitis C virus (HCV) by lowering serum lipopolysaccharide (LPS), a protein in blood that comes from the bacteria in intestines and may cause scarring in the liver.

Approximately 60 subjects will participate in this study. Subjects will be part of the study for approximately 1 year post transplant.
