Haemophilus influenzae meningitis. A comparison between chloramphenicol and ampicillin therapy with special reference
Abstract:
131 patients suffering from meningitis due to Haemophilus influenzae or parainfluenzae were re-examined after 1-15 years, using hospital records, questionnaires, and audiological examination, especially to compare chloramphenicol and ampicillin therapy. Mortality was 3.8%. Subdural effusions occurred in 14.5% of cases uni- or bilaterally. There was deafness in 2.3%, and moderate hearing loss in 8.4%. Convulsions appeared later in 6.9%. The final outcome was good in 60%. The most important factors in prognosis seemed to be the severity of the symptoms and the condition of the patient on admission to hospital. No clear difference was seen between the results of chloramphenicol and ampicillin therapy, but total loss of vestibular function was found in 3 cases in the ampicillin group, and in none in the chloramphenicol group. In mortality and deafness, the differences in outcome were similar, although not statistically significant. As these observations show, the therapy used in Haemophilus influenzae meningitis needs re-evaluation.
Insights
This study on Haemophilus influenzae meningitis found that while both chloramphenicol and ampicillin had similar outcomes, ampicillin was linked to vestibular dysfunction. Treatment strategies for this serious infection require re-evaluation.
Area of Science:
- Pediatrics
- Infectious Diseases
- Neurology
Background:
- Meningitis caused by Haemophilus influenzae (HI) is a significant pediatric concern.
- Long-term sequelae of HI meningitis necessitate comprehensive follow-up and treatment evaluation.
Purpose of the Study:
- To compare the long-term outcomes of chloramphenicol versus ampicillin therapy for Haemophilus influenzae meningitis.
- To identify prognostic factors influencing the recovery and potential complications of HI meningitis.
Main Methods:
- Retrospective analysis of 131 patients with HI meningitis, re-examined 1-15 years post-infection.
- Data collection included hospital records, patient questionnaires, and audiological examinations.
- Comparison of therapeutic outcomes between chloramphenicol and ampicillin treatment groups.
Main Results:
- Overall mortality was 3.8%; 14.5% experienced subdural effusions.
- Long-term sequelae included deafness (2.3%), hearing loss (8.4%), and late-onset convulsions (6.9%).
- Ampicillin therapy was associated with total loss of vestibular function in 3 cases, not observed with chloramphenicol.
Conclusions:
- Prognosis is primarily determined by symptom severity and patient condition upon admission.
- While no statistically significant differences in mortality or deafness were found between antibiotics, ampicillin's association with vestibular dysfunction warrants further investigation.
- Current therapeutic approaches for Haemophilus influenzae meningitis require re-evaluation based on long-term patient outcomes.
