INIS - future
• Aim– To reach a target of at least 3500 babies by
end of recruitment 31st May 2007
INIS hypothesis
• That, in infants receiving antibiotics for clinical sepsis, the addition of non-specific immunoglobulin (IVIG) reduces mortality and major morbidity compared with antibiotics alone
INIS - study design
• Gold standard for treatment trials
• Double-blind
• Randomised
• Placebo -controlled
Receiving antibiotics and proven or
suspected serious infection
Mortality or major disability
IVIG
at 2 years
Placebo
Eligibility criteria
1.Receiving antibiotics and suspected or proven serious infection
AND ………
Eligibility criteria2. At least one of the following:
birth weight less than 1500greceiving respiratory support via an
endotracheal tube evidence of infection in blood culture, CSF or
usually sterile body fluid
AND………
Eligibility criteria
AND ………
3. There is substantial uncertainty that IVIG is indicated
Exclusion criteria
• IVIG already given*
• IVIG thought to be needed or contraindicated
*specific IVIG
Specific IVIG
• IVIG for specific indications should be given as per hospital policy and these infants will still be eligible
– Hepatitis B immunoglobulin– Varicella-Zoster immunoglobulin
Eligibility - age
• Babies at any age whilst resident on NICU
• After discharge babies are eligible until EDD plus 28 days
Consent
• Consent must be fully informed and obtained before randomisation
• Use the Information Leaflet
• Direct parents to website or INIS contact
Randomisation
• Simple, no phone call required
• Drug boxes in pre-randomised sequence
• Use lowest numbered box
IVIG
• Plasma from non-UK donors
• Produced by Scottish National Blood Transfusion Service
• Tested for HIV 1 ,2 and Hepatitis A,B,C
• Excellent safety record
• Few adverse reactions
Placebo
• 0.2% albumin
• Identical appearance to IVIG
• Safety record as for IVIG
Follow-up
• Parent questionnaire
• Paediatrician questionnaire
• Completed at 2 year corrected age
Primary outcomes
• Death or
• Major disability at 2 years corrected age
Secondary outcomes• Short term
– Death, chronic lung disease or major cerebral abnormality before hospital discharge
– Significant positive culture after trial entry– Pneumonia– NEC– Duration of respiratory support
Secondary outcomes
• Long term– Death before 2 years– Major disability at 2yrs– Non-major disability at 2yrs
Case scenarios
Eligible?
• 29 weeks gestation• Deterioration day 34• Recurrent apnoeic episodes• Prolonged cap. refill time• CRP 66• Commenced on antibiotics • CNS in blood culture
Eligible?
Remember
• It is NOT TOO LATE to randomise an infant after a positive blood culture has been reported
• IVIG may be of benefit after the inflammatory process has begun
Eligible?
• 27 weeks gestation, 1.3kg
• PROM 27 hrs
• GBS on maternal HVS
• Intrapartum antibiotics not given
• Asymptomatic infant
• Antibiotics commenced as hospital policy
Eligible?
But
• If there was offensive liquor, raised inflammatory markers or this baby was to become unwell
This baby would be eligible for INIS
Eligible?
• Term infant
• Cyanotic episodes at 2hrs age
• Apnoeic requiring ventilation
• CXR patchy consolidation both lung fields
• Commenced on antibiotics
• CRP 19
