Pulmonary complications in adult measles]

The clinical features of pulmonary complications were evaluated in 15 patients with adult measles diagnosed by clinical and serologic investigations. Of those 15 patients, 12 were admitted because of high fever, sever anorexia and dyspnea. Almost all patients were found to have thrombocytopenia, elevations of LDH and aminotransferase. Pulmonary infiltrates were present in only 2 of the 12 patients (16.7%) on whom chest roentgenograms were performed, but hypoxemia (PaO2 < 70 Torr) were present in 8 of the 12 patients (66.7%). Pulmonary function tests in 8 patients showed mild decrease in VC, moderate decrease in FEV1 and severe decrease in V25. These findings suggest that hypoxemia in patients with normal chest radiographs may be largely caused by bronchiolitis. The observations of sequential peak flow rate measurement showed that severe pulmonary dysfunction continued for 4-5 days after the onset of the rash. To avoid the development of respiratory failure, patients with measles should be carefully monitored for bacterial superinfections of the respiratory tract especially within several days after the appearance of the rash.
