Can an antioxidant boost the Body's fight against a deadly infection in cirrhosis?
NCT ID NCT07803952
First seen Sep 04, 2026 · Last updated Sep 09, 2026 · Updated 2 times
Summary
This trial tests whether adding N-acetylcysteine (NAC), an antioxidant, to standard care improves early response in people with liver cirrhosis who develop spontaneous bacterial peritonitis (SBP), a serious infection of the abdominal fluid. Researchers will give 60 adults either NAC or a placebo twice daily for 7 days alongside usual antibiotics and albumin. They will measure changes in infection markers in the abdominal fluid after 48 hours and track organ function and short-term outcomes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- N-acetylcysteine (NAC) given as an add-on to standard therapy
- What this could lead to
- If it works, adding NAC to standard care could reduce treatment failure, organ damage, and early death in people with cirrhosis and spontaneous bacterial peritonitis.
- What could go wrong
- This is an early-phase trial with only 60 participants, so results may not apply broadly. NAC may not improve outcomes and could cause side effects like nausea or allergic reactions.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: Adult patients (≥18 years) with liver cirrhosis, confirmed by clinical, radiological, or histopathological findings, who are newly diagnosed with SBP based on an ascitic fluid polymorphonuclear (PMN) leukocyte count ≥250 cells/mm³ according to the American Association for the Study of Liver Diseases (AASLD) criteria (2). Eligible participants were required to have undergone diagnostic paracentesis for ascitic fluid analysis and to provide informed consent prior to enrollment. Exclusion Criteria * Secondary bacterial or fungal peritonitis. * Recent abdominal surgery or requiring immediate surgical intervention. * Known hypersensitivity to NAC. * Pregnancy or lactation. * Septic shock, established HRS-AKI requiring rescue therapy, or renal replacement therapy at enrollment. * Advanced malignancy or terminal illness. * Previous NAC administration during the current SBP episode. * Inability to receive oral study medication. * Participation in another interventional trial that may affect study outcomes.
