Associated neoplasm (active cancer [of whatever type, solid or haematological] or diagnosed within the year other than basocellular skin cancer).

Severe or very severe chronic obstructive pulmonary disease (COPD) (GOLD3 and GOLD4).

History of bacterial pneumonia in the past 12 months.

Bronchopulmonary diseases likely to interfere with the assessment of the therapeutic response.

Known hypersensitivity to streptogramins, penicillin and other betalactamines or excipients of the treatments studied.

History of severe skin reaction after taking pristinamycin or amoxicillin.

Kidney disease (chronic kidney failure or creatinine clearance 30 mL/minute).

Patients treated with allopurinol, colchicine, immunosuppressants (cyclosporin, tacrolimus, mycophenolate mofetil, methotrexate, biotherapies) oral anticoagulants in the previous 6 months or during the study.
