Haemophilus influenzae infection among children with acute bacterial meningitis.

Objective: To determine the frequency of haemophilus influenzae infection in children less than 5 years with acute bacterial meningitis (ABM). Study Design: Descriptive Cross Sectional study. Setting: Department of Pediatric Medicine, The Children’s Hospital and Institute of Child Health, Multan. Period: October 2019 to March 2020. Material & Methods: A total of 165 children aged 5 – 60 months of either gender having acute bacterial meningitis with duration of < 2 weeks were enrolled. Cerebrospinal fluid (CSF) of each child was sent for microbiological analysis. Results: There were 106 (64.2 %) boys and 59 (35.8 %) girls. Mean age was 2.72 ± 1.07 years. Most cases, 112 (67.9 %) belonged to urban areas.  Maternal literacy was positive in 65 (39.4%) cases while 59 (35.8%) were fully vaccinated. Mean disease duration was 56.25 ± 15.36 hours and 112 (67.9%) had duration of illness more than 36 hours. Frequency of Haemophilus Influenzae was noted in 35 (21.2%) cases. Conclusion: Frequency of Haemophilus Influenzae was high among children with acute bacterial meningitis. Early diagnosis and appropriate management might help reducing prolonged hospitalization and disease morbidity related to Haemophilus Influenza.
