Lower respiratory tract disease in children: constant pathogens - constant management?!

BACKGROUND

This study analyses the pathogens of acute lower respiratory tract infections (LRI) in children in a German community hospital over six years. Against this background the adoption of new diagnostic and therapeutic guidelines for the LRI management and of RSV-cases in particular is studied.

METHODS

1054 children aged zero to 36 months hospitalized with LRI were prospectively included in the surveillance studies "Parainfluenzavirus (PIV) and Respiratory syncytial virus (RSV) infections in Germany [PRI.de] 1999-2001" and the "pediatric infectious diseases network on acute respiratory tract infections" [PID-ARI.net] for the time period of October 2002 until June 2005. The nasopharyngeal aspirates (NPA) of these children had been analysed for RSV, PIV 1,2,3 and influenzavirus (IV)-A, -B. In 2003/2004 the national guideline on how to diagnose and treat RSV-disease (bronchiolitis) changed. Data on LRI cases severity and especially those regarding the clinical management of RSV-infections were compared to see differences following the release of the guideline.

RESULTS

84% of the children were between zero and 24 months old. 34% of the NPA specimens were positive for RSV, 7.7% for PIV 1,2,3 and 4.7% for IV-A, -B. Epidemiological findings did not differ substantially between the two studies. Clinical management of RSV-LRI, especially drug use, did not change except for the lower rate of x-ray examination (p<0.01).

CONCLUSION

The spectrum of causing agents in LRI of children remained quite stable over of six years. Diagnostic and therapeutic concepts remain also stable in a situation where new guidelines were introduced, but not reinforced.
