Cystic fibrosis diagnosed in an elderly man

Respiration. Jan-Feb 2004;71(1):98-100. doi: 10.1159/000075659.


Although most patients with cystic fibrosis (CF) are diagnosed in early childhood, the diagnosis may be delayed for patients with mild symptoms or single-organ disease. We describe a man with known infertility and a history of productive cough diagnosed with CF at 61 years of age. The patient carries two mutations and one variant in the CF transmembrane conductance regulator gene: 394delTT, P99L and R75Q. During a 15-year follow-up time he has developed significant pulmonary disease.
