Adding N-acetylcysteine to steroid treatment for severe alcoholic hepatitis (Maddrey >32)

Utility of the Use of N-acetylcysteine Associated With Conventional Treatment in Patients With Severe Acute Alcoholic Hepatitis (Maddrey> 32)

Not applicable Interventional Bioaraba Health Research Institute · NCT05294744

This trial will try whether adding N-acetylcysteine to standard steroid treatment helps adults aged 18–75 with severe alcoholic hepatitis (Maddrey ≥32) have fewer complications and a lower risk of death than steroids alone.

What this trial studies

Adults with severe acute alcoholic hepatitis (Maddrey score ≥32) are randomized in an open-label, multicenter, parallel-design trial to receive standard corticosteroid therapy with or without adjunctive N-acetylcysteine (NAC). The trial compares morbidity and mortality between the two groups and records safety and adverse events related to both treatments. Eligible patients meet AASLD criteria or have compatible liver histology and are aged 18–75 years. The randomized, controlled, pragmatic design aims to provide clearer evidence on whether NAC adds benefit to current steroid-based care.

Who should consider this trial

Good fit: Adults aged 18–75 with severe acute alcoholic hepatitis (Maddrey ≥32) meeting AASLD criteria or compatible liver histology who can provide informed consent.

Not a fit: Patients with allergy to NAC or corticosteroids, uncontrolled active infection, significant renal failure (creatinine >2.5 mg/dL), hepatocellular carcinoma, portal cavernomatosis, other life-limiting illnesses, or those on contraindicated medications are excluded and unlikely to benefit.

Why it matters

Potential benefit: If successful, adding NAC to steroids could reduce complications and short-term deaths in patients with severe alcoholic hepatitis.

How similar studies have performed: Previous smaller studies of NAC in alcoholic hepatitis have reported mixed results, so the benefit remains unproven and larger trials are recommended.
