Study information

Scientific title


Study hypothesis

Primary objective:
To determine if the bacteriologic failure* between 6 - 40 days is equivalent (after randomising the day 5 survivors) between 10 days versus 5 days of ceftriaxone therapy for treatment of acute bacterial meningitis in children aged 2 months up to 12 years.

Secondary objectives:
1. In children who receive 5 versus 10 days of ceftriaxone therapy for acute bacterial meningitis following rates will be compared by day 40 (after admission):
1.1. Mortality rates by day 40
1.2. Hearing loss on day 40
1.3. Blindness on day 40
1.4. Neurologic, motor deficits by day 40
1.5. Treatment failure
1.6. Bacterial pathogens
2. In children who receive 5 versus 10 days of ceftriaxone therapy for acute bacterial meningitis we will compare the rates of the following at 190 + 30 days after admission:
2.1. Mortality rates
2.2. Hearing loss
2.3. Blindness
2.4. Neurologic, motor and developmental deficits

*Bacteriologic failure will be reappearance of bacteria in CSF between 6-40 days

Please note that after discussions with the Data Safety Monitoring Board (DSMB), the following was decided:
1. In the DSMB meeting in 2002, in order to improve enrolment, the age of enrolment was increased to 144 months. Therefore, the upper limit of weight was also increased from 18.5 kg (see changes made to inclusion criteria)
2. In the DSMB meeting in 2006, due to the challenge in enrolling 1500 children (the original target number of participants, the DSMB decided to stop enrolment after reviewing the interim analysis data. They felt that continuing the trial to achieve the sample size to that originally planned is unlikely to alter in an important way the findings, or the recommendations based on those findings.

Primary outcome measure

Rate of bacteriologic failure defined as:
1. Cerebrospinal Fluid (CSF) or blood culture positive* on day 6 to 40 for original organism, or
2. CSF or blood culture positive on days 6 to 40 in a patient who had culture negative bacterial meningitis

Note: Repeat lumber puncture will be done between 48-72 hours of admission. A repeat blood cultures will only be done if condition of the patient requires it.

*for H. influenzae, S. pneumoniae, N. meningitidis

Secondary outcome measures

1. Perceived treatment failure
2. Hearing loss: Day 40 screen Otoacoustic Emissions (OAE), Auditory Brainstem Response (ABR) greater than 40 db
3. Blindness diagnosed at day 40
4. Motor deficit at day 40 including:
4.1. Two or more abnormalities of tone or strength in any of the limbs or neck, or
4.2. Any palsy of VI or VII cranial nerves
5. Developmental score: abnormal developmental screening on day 190 + 30 days as evaluated by Denver Screening method
6. Seizures: any seizure without fever presenting on days 10 to 40 or 41 to 190 + 30 days
7. Hydrocephalus: defined as any patient with ventriculo-peritoneal shunting or clinical signs and head circumference measurements consistent with hydrocephalous and the perceived need of ventricular derivation
8. Death of an enrolled patient by any cause between days 6 - 40
9. Death of an enrolled patient by any cause between 41 - 190 days
10. Bacterial pathogen
