Chronic rejection (or Bronchiolitis Obliterans syndrome-BOS) is a major cause of mortality and morbidity after lung transplantation. Because montelukast has been shown to be of some efficacy in a similar disease (Obliterative Bronchiolitis after bone marrow transplantation), the investigators would like to test if montelukast can indeed slow down the progression of chronic rejection after lung transplantation.

Primary Outcome Measures:
  • survival/retransplantation rate after diagnosis of BOS [ Time Frame: 1 year after diagnosis ] [ Designated as safety issue: No ]
  • survival/retransplantation rate at 2 years after diagnosis [ Time Frame: 2 years after diagnosis ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Obstructive and restrictive pulmonary function evolution [ Time Frame: during 1 and 2 years of treatment ] [ Designated as safety issue: No ]
  • Bronchoalveolar lavage fluid (BAL) [ Time Frame: during 1 and 2 years of treatment ] [ Designated as safety issue: No ]
    BAL will be used to assess cellularity, protein and mRNA concentration and microbiology

  • peripheral blood [ Time Frame: during 1 and 2 years of treatment ] [ Designated as safety issue: No ]
    peripheral blood will be used to assess C-reactive protein, protein and mRNA concentration and fibrocytes content

  • Cytomegalovirus (CMV) and non-CMV infection rates [ Time Frame: during 1 and 2 years of follow up ] [ Designated as safety issue: No ]
  • Acute rejection and lymphocytic bronchiolitis rates [ Time Frame: after 1 and 2 years of treatment ] [ Designated as safety issue: No ]

Enrollment: 30
