Abstract:
1. An acute purulent meningitis due to the invasion of the meninges by Pfeiffer's influenza bacillus is not a very uncommon disease ininfants and young children. It has a very high mortality. 2. Complement is entirely absent in the cerebrospinal fluid of these cases, and bactericidal experiments suggest that the injection of a specific antiserum will have but slight lethal effect on the organisms unless complement is injected at the same time. 3. Treatment with a mixture of specific antiserum and complement led in some cases to a definite clinical improvement, coincident with sterilization and clearing of the cerebrospinal fluid. But after some days, the patients relapsed and died. Autopsy showed localized abscesses in the vicinity of the base of the brain, the lesions being definitely walled off from the general subarachnoid space. In one case, the patient recovered. 4. Since the walls of the abscesses apparently present an insuperable mechanical obstacle to the action of the antiserum and complement, the possibility of preventing the formation of abscesses is discussed. Earlier diagnosis and more rapid sterilization are the most obvious measures. Bactericidal experiments indicate that the proportion of antiserum to complement may be an important factor in bringing about a more rapid elimination of the bacilli.
Insights
Pfeiffer
Area of Science:
- Pediatrics
- Infectious Diseases
- Immunology
Background:
- Acute purulent meningitis caused by Pfeiffer's influenza bacillus is a severe, often fatal, childhood illness.
- Cerebrospinal fluid in these cases lacks complement, hindering the effectiveness of specific antiserum treatment.
- Bactericidal experiments indicate that complement is crucial for antiserum efficacy against Pfeiffer's influenza bacillus.
Purpose of the Study:
- To investigate the therapeutic potential of combining specific antiserum with complement for treating Pfeiffer's influenza bacillus meningitis.
- To understand the role of complement in the efficacy of antiserum treatment for bacterial meningitis.
- To explore strategies for preventing abscess formation in treated meningitis cases.
Main Methods:
- Treatment of patients with a combination of specific antiserum and complement.
- Monitoring of clinical improvement, cerebrospinal fluid sterilization, and patient outcomes.
- Autopsy examination to identify pathological changes, including abscess formation.
Main Results:
- Combined antiserum and complement therapy led to temporary clinical improvement and cerebrospinal fluid sterilization in some patients.
- Patients who relapsed developed localized brain abscesses, walled off from the subarachnoid space, leading to fatal outcomes.
- One patient recovered, suggesting potential for successful treatment under certain conditions.
Conclusions:
- While combined antiserum and complement therapy shows promise, abscess formation presents a significant challenge to treatment success.
- Preventing abscesses through earlier diagnosis and more rapid bacterial elimination is critical.
- Optimizing the antiserum to complement ratio may enhance bacterial clearance and improve treatment outcomes.
