Main objective

Scope: Safety, Therapy, Efficacy

Demonstrate that an antibiotic therapy (ATB) of 3 weeks after drainage of pyogenic liver abscess is non-inferior in terms of treatment failure at week 12 after drainage, compared to a 6 weeks ATB.

Secondary objectives 10

  1. 1- Demonstrate that 3 weeks ATB is non-inferior to 6 weeks in terms of mortality of any cause.
  2. 2- Demonstrate the superiority of 3 weeks ATB versus 6 weeks in terms of emergence of digestive colonization by MDRB.
  3. 3- Compare the proportion of patients with a treatment failure at the end of the ATB assigned by the randomization.
  4. 4- Compare the proportion of patients with complete regression of liver abscess(es) images at weeks 3, 6, and 12 after drainage, overall, and according to the ATB duration,
  5. 5- Compare the time to hospital discharge, overall, and according to the ATB duration, the abscess’ and patient’s characteristics.
  6. 6- Describe the intercurring events between week 12 and month 6 in each group (e.g. relapse of index infection, new liver abscess(es), death from any cause,…)
  7. 7- Describe the clinical, anatomical, and microbiological characteristics of the pyogenic liver abscess(es).
  8. 8- Describe the characteristics and modalities of the antibiotic therapy administered to the participant (molecules, modalities, duration).
  9. 9- Identify risk factors of failure of treatment, overall, and according to ATB duration.
  10. 10- Evaluate the safety of each treatment protocol
