Bronchiolitis obliterans affects up to 5.5% of people who have received HSCT. [21] One of the biggest risk factors after HSCT is the development of GVHD with a 14% risk. [ 22 ] Other risk factors post transplant including tobacco use, age of donor, age of recipient, lower baseline FEV1/FVC ratio, non-caucasian race, peripheral and lower ...

This medicine does not effectively treat a viral infection like sore throats, influenza, bronchitis, sinusitis and common respiratory tract infections.
