Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
3 billion Colony Forming Units (CFU)/ day of a combination of Bifidobacteria probiotic (1 billion CFU each of B. breve M-16V, B. longum subsp. infantis M-63 and B. longum subsp. longum BB536) given orally daily starting with first feed after birth and continued for a period of 4 months (till weaning started). Adherence to intervention will be monitored by clinical trials pharmacy by checking sachets consumed and frequency of picking up repeat prescription of the probiotic/ placebo

Treatment: Other
Comparator / control treatment
Control group will receive placebo (dextrin) with similar weight and packaging as the probiotic
Control group
Placebo

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Opaque, sealed, coded envelopes will be used for randomization. Neonates of multiple pregnancies will be considered as separate participants. Allocation concealment will be optimized by prescribing allocation only after informed parental consent and recording baseline neonatal data.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Group assignment will be allocated by a computer-generated randomization sequence in randomly ordered block sizes of 2 and 4. Opaque, sealed, coded envelopes will be used for randomization.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?

The people administering the treatment/s

Statistical methods / analysis
The analysis will be based on the intention to treat principle. Continuous data will be summarized using median, interquartile range and range. Categorical data will be summarised using frequency distributions. Univariate comparisons for continuous data will be made using the Mann Whitney test. For categorical data, the Chi-square or Fisher exact test will be used. SCFA data will be analysed using linear mixed model effects (LME) test to assess differences between the groups over time. In this analysis, subjects will be modelled as a random factor and time and treatment as fixed factors. All tests will be two-sided and a p-value <0.05 will be considered significant. Data on clinical outcomes will be analysed using SPSS version 22.0 statistical software (Armonk, NY: IBM Corp) and SCFA in R (version 3.5.1).

Summary
Brief summary
Infants born to mothers with gestational diabetes have abnormal gut bacteria, which may predispose them to adverse health outcomes such as inflammatory disorders, allergies, diabetes, obesity, neuro-developmental and neuro-behavioural impairment, cardiovascular and immune-mediated diseases. We aim to supplement these infants with probiotics to alter the bad bacteria with the hope to improve their health outcomes. Currently there are no trials in this area.
