Aim Minimal hepatic encephalopathy ( MHE ) impairs daily functioning and health‐related quality of life in chronic liver disease ( CLD ). Lactulose is the standard treatment but has side‐effects. Probiotics have an encouraging role in MHE . The aim of the present study was to test whether probiotics are non‐inferior to lactulose in improving MHE . Methods Patients with CLD ( n  = 227) were screened for MHE using neuropsychometric tests (number connection tests A and B [or figure connection tests A and B ]) and/or neurophysiological test ( P ‐300 auditory event‐related potential), and 120 (53%) were diagnosed with MHE by abnormal tests. MHE patients were randomized to lactulose (30–60 mL/day) or probiotic (four capsules of VSL #3; total of 450 billion CFU /day) for 2 months. Response was defined as normalization of tests. Serum ammonia was measured by commercial kit. Results Of 120 patients randomized, 40 in the lactulose arm and 33 in the probiotic arm completed 2 months of intervention. MHE improved in 25 (62.5%) patients taking lactulose and 23 (69.7%) taking probiotics. The effect size of difference of improvement in MHE between lactulose and probiotic was 0.072 per per‐protocol analysis and 0.040 as per intention to treat analysis (within −20% of non‐inferiority margin). Serum ammonia was comparable between groups at baseline and 2 months; it decreased in patients in whom MHE improved, while increased in patients with no improvement in MHE . Conclusion The probiotic VSL #3 was non‐inferior to the standard therapy, lactulose in the treatment of MHE . Improvement in MHE correlated with reduction of ammonia levels.
