Brief background Introducing probiotics in AustraliaRegulatory approach towards unregistered drugs (probiotics)
Process followed by Nepean Hospital Sydney, to introduce probiotics in tertiary institute
Necrotising enterocolitis (NEC) Commonest GI emergency of unknown cause
Incidence 5-6% in <32 weeks & VLBW 9-10% in <28 weeks
Mortality (20-40%), higher in <1000grams
Morbidity – cerebral palsy Expensive
$100,000 to $250,000/NEC case
USA – $1 billion/yearBisquera JA, Pediatrics 2002Neu NEJM 2011

Updated Meta-analysis of Probiotics for Preventing Necrotizing Enterocolitis in
Conclusive meta‐analysis
Results (11 trials n=2176)Outcome RR 95% CI p‐values

Trial sequential analysis
Conclusion (Pediatrics 2010) It is unlikely that ongoing RCTs will change the results of meta‐analysis
“Probiotics should be offered routinely provided safe and effective product is available”
A RCT of 2000 neonates and a baseline incidence of 8% would have to show a doubling of the incidence of NECto overturn the benefits shown in the trials completed to date. Such a reversal of effects has never been demonstrated in clinical medicine.

Probiotics regulation in Australia Food supplement vs. drug
FSANZ vs. TGA (equivalent to FDA)
Status of probiotic as food or drugs is not clear in Australia
Intent to use: Pharmaceutical or food supplement Prevention of NEC – classified as drug Currently there are no registered drug quality probiotics in Australia and many other countries
Access to unregistered drugsSpecial Access Scheme (SAS Category A or Category B)Clinical trials (CTN or CTX)Authorised prescriber pathway
Stepwise approach at Nepean1. Develop evidence based guidelines to use routine
probiotics2. Identifying a suitable probiotic product 3. Approval of selected probiotic product (overseas) from
local area drug and therapeutics committee. 4. Endorsement from local Ethics Committee and prepare
parent information sheet 5. Authorised Prescriber application to TGA, Australia6. Approval from authorities regarding importing probiotic
product from overseas 7. Independent quality assessment of the product 8. Develop the practical protocol for routine use 9. Perform prospective audit after introducing routine
probiotics for prevention of NEC and monitor safety
Evidence based guidelines
Deshpande et al, BMC Medicine 2011:92
Independent quality assessmentMicrobiology and University laboratory FAO/WHO 2001, (G Reid, Sanders ME), GMP guidelines of Australia and Italy
Taxonomy confirmation of strains (Infloran: lactobacillus acidophilus and bifidobacterium bifidum)
Colony count, rule out contaminants (fungus, gram negatives)
Sterility certificate from manufacturer Antibiotic sensitivity (Penicillin MIC:2 ugram/mL)
QA for every new batch of probiotic supplement
