Study summary

Patient with liver cirrhosis commonly have co-existing small bowel bacterial overgrowth (SIBO) yet may be asymptomatic. It is unclear as to the value of treating SIBO in asymptomatic individuals. Cirrhosis increase permeability of the gastrointestinal mucosa. It is postulated that in cirrhosis, endotoxins translocate across the gut mucosal barrier resulting in a second hit within hepatocyte perpetuating decompensation and spontaneous bacterial peritonitis. We hypothesise that cirrhosis patients with concomitant SIBO are particularly vulnerable for endotoxin translocation and would benefit from treatment. Treatment of SIBO would reduce the risk of spontaneous bacterial peritonitis and other liver-related morbidities. We aim to treat a cohort of patients with severe liver disease and concomitant SIBO with antibiotics as prophylaxis and compare the risk of spontaneous bacterial peritonitis, further liver-related morbidity and survival against untreated asymptomatic controls.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Interventions

What researchers measure

Primary outcomes

  1. Incidence of Spontaneous bacterial peritonitis

    To determine the rate of cirrhosis-related complications, with and without Rifaximin among decompensated cirrhosis with SIBO.

    Time frame: 12 months

Secondary outcomes

  1. Incidence of all liver related events (hepatic encephalopathy, variceal bleeding, acute on chronic liver failure)

    To study and understand the immunophysiological and gut microbiota changes associated with bowel decontamination among cirrhosis patients with SIBO using serum biomarkers.

    Time frame: 12 months
