CLArithromycin Versus AZIthromycin in the Treatment of Mycobacterium Avium Complex (MAC) Lung Infections
Centre Hospitalier Universitaire, Amiens
424 participants
Feb 5, 2018
INTERVENTIONAL
Conditions
Summary
MAC lung infections are a growing public health problem. The ATS / IDSA 2007 guidelines for the treatment of these non-tuberculous mycobacterial infections recommend the use of a macrolide or azalide (clarithromycin or azithromycin), rifampicin or rifabutin and ethambutol. For MAC disseminated infections, several studies have compared combinations containing clarithromycin or azithromycin and found no significant difference in efficacy. No randomized controlled trials have been performed for pulmonary infections to compare clarithromycin and azithromycin in terms of efficacy. Clarithromycin is often used as a first-line treatment in France, but its tolerance is often poor, particularly in terms of risk of hepatitis, metallic taste in the mouth, nausea or vomiting, and it interacts with many drugs via cytochrome p450 . In particular, it increases the toxicity of rifabutin, in particular in terms of uveitis. Azithromycin has fewer side effects especially less digestive toxicity and drug interactions than clarithromycin. The hypothesis is therefore that the efficacy of azithromycin would be non-inferior in comparison with that of clarithromycin.
Eligibility
Inclusion Criteria4
- patients 18 years of age or older
- having a positive Mycobacterium avium complex sample showing the ATS / IDSA infection criteria and requiring treatment
- ATS / IDSA infection criteria combine clinico-radiological criteria, associated with microbiological criteria

- Renal insufficiency with creatinine clearance less than 30 ml / min,
- Pregnancy and breast feeding,
- Contra-indication to one of the antibiotics,
- Impossibility to follow the protocol due in particular to drug addiction according to the investigator,
- Limited life expectancy, less than 6 months,
- Patient already participating in a clinical trial on a medical treatment or a therapeutic strategy for non-tuberculous mycobacteria.
