[Ciliary function in bronchopulmonary infections in childhood].
It was the aim of this study to examine the influence of bacterial or viral infections of the airways on the ciliary beat rate in childhood. In 21 children with bacterial bronchopulmonary infections a mean ciliary beat rate of 9.1 +/- 2.4. Hz was found that did not differ significantly from that of the group of the healthy subjects (9.9 +/- 1 Hz). In 7 of the 21 patients we could identify an infection of the respiratory tract with Haemophilus influenzae; in those children there was a marked reduction of the mean ciliary beat rate at 8 Hz. 13 children with viral bronchopulmonary infections had a mean ciliary beat rate of 11.8 +/- 1.8 Hz, which is significantly enhanced when compared with that of the healthy group. Compared with the mean ciliary beat rate of bacterial infections of the respiratory tract there is a significant difference. In viral infections of the airways no value below 9 Hz was found. In case of markedly reduced ciliary beat rate a bacterial infection must be assumed.
