[Respiratory infections associated with a cytomegalovirus]

We report 27 children with respiratory tract disease in whom cytomegalovirus was isolated. These group excludes transplant patients and those on hemodialysis and mononucleosis. At the time of virus studies 7 had pneumonia, 3 chronic bronchopneumopathy, 2 bronchopneumonia, 8 pertussoid syndrome, 6 bronchitis or bronchiolitis and 1 laryngitis with glottic oedema. Virus studies consisted in cell cultures of biological products (pharyngeal exudates and urine). They were positive in 18 pharyngeal exudates, 24 urines, 2 bronchial brushings and 1 bronchoaspiration. In only 5 patients a complete serologic study was performed, with 3 seroconversions and one case of persistent high titers. Three patients had severe immune disease (2 hipogammaglobulinemias) and 1 dysgammaglobulinemia. These findings are discussed.
