Summary
White blood cell count (WBC), erythrocyte sedimentation rate (ESR) and serum C-reactive protein (CRP) were determined upon diagnosis of 61 children with bacterial meningitis in order to compare the responses evoked by different bacteria. The age of the patients and the duration of their symptoms were similar in all groups. WBC and ESR corresponded significantly with the bacterial species. The mean WBC inHaemophilus influenzae (n=44), meningococcal (n=11) and pneumococcal (n=6) infection were 14,605/µl, 19,391/µl and 23,833/µl, respectively (forH. influenzae and pneumococci p<0.001). The mean ESR varied from 58 mm/h (meningococci) to 100 mm/h (pneumococci) (p<0.025). CRP was the test least influenced by the nature of the bacteria. The characteristics of CRP suggest its superiority over WBC and ESR as a detector of bacteremic infections. WBC is unsuitable for screening of systemicH. influenzae disease.
Zusammenfassung
Die Leukozytenzahl, Blutkörperchensenkungsgeschwindigkeit (BKS) und das C-reaktive Protein (CRP) wurden bei 61 Kindern mit bakterieller Meningitis zum Zeitpunkt der Diagnose bestimmt, um die durch verschiedene Bakterien verursachten Reaktionen zu vergleichen. In allen Gruppen waren Alter der Patienten und Dauer der Symptome ähnlich. Zwischen Leukozytenzahl, BKS und den verschiedenen Bakterien-Spezies bestand eine signifikante Beziehung. Die mittleren Leukozytenzahlen bei Infektionen durchHaemophilus influenzae (n=44), Meningokokken (n=11) und Pneumokokken (n=6) betrugen 14 605/µl, 19 391/µl und 23 833/µl (H. influenzae und Pneumokokken p<0,001). Die mittlere BKS lag zwischen 58 mm/h (Meningokokken) und 100 mm/h (Pneumokokken); (p<0,025). Das CRP wurde von den untersuchten Parametern am wenigsten von der Art der Bakterien beeinflußt. Die Eigenschaften des CRP lassen annehmen, daß es für den Nachweis bakteriämischer Infektionen der Leukozytenzahl und der BKS überlegen ist. Für das Screening auf systemische Erkrankungen durchH. influenzae ist die Leukozytenzahl ungeeignet.
