What this Trial Is About

Researchers are evaluating the safety and effectiveness of stopping antibiotic treatment early in adults hospitalized with respiratory viral infections. This study focuses on patients with moderately severe disease who test positive for respiratory viruses such as influenza, respiratory syncytial virus, parainfluenza virus, or human metapneumovirus. The goal is to determine if early discontinuation of antibiotics leads to similar clinical outcomes compared to continuing antibiotic therapy, aiming to reduce unnecessary antibiotic use and combat antimicrobial resistance. Participants are randomly assigned to either stop antibiotic therapy as started by their admitting physician or to continue antibiotic therapy without changes. The study monitors early clinical response at 120 hours after randomization, defined by survival with symptom improvement and no need for rescue antibiotics. Secondary assessments include mortality rates, hospital stay duration, antibiotic use, and readmission rates, all measured during hospital admission and up to 30 days after discharge. During the trial, participants undergo nasopharyngeal swab testing to confirm viral infection and are monitored closely for symptoms, survival, and antibiotic use. Researchers evaluate clinical response at 120 hours and track outcomes such as mortality, hospital stay length, and antibiotic doses until discharge and 30 days later. The study aims to gather detailed safety and efficacy data over the hospital stay and follow-up period, supporting more targeted antibiotic use in viral respiratory infections.

Eligibility Criteria

Eligible

You may qualify if you...

  • Hospitalized
  • Adults 18 years or older
  • Moderately severe disease (CRB65 64 2 at time of inclusion)
  • Nasopharyngeal swab positive for influenza virus, parainfluenza virus, respiratory syncytial virus (RSV) or human metapneumovirus (hMPV)
  • On antibiotic therapy as instituted by the receiving physician from the emergency department
  • Signed informed consent obtained and documented according to regulations
Not Eligible

You will not qualify if you...

  • Requiring ICU admission at screening
  • Requiring high-flow oxygen therapy or non-invasive ventilation at screening
  • Signs of severe pneumonia (abscesses, massive pleural effusion, a well-defined lobar infiltrate on chest X-ray strongly suggestive of bacterial etiology)
  • Not immunocompetent (e.g., active chemotherapy, corticosteroid therapy 65 20 mg prednisolone daily for 65 4 weeks, chronic immunosuppression due to organ transplant)
  • SARS-CoV-2 positive
  • Bacteremia
  • Urine antigen test positive for legionella
  • Any other infection requiring antibiotic treatment
  • Antibiotic use for assumed airway infection within 24 hours before hospital admission
  • More than 48 hours since starting antibiotic therapy at screening
