Role of probiotics VSL#3 in prevention of suspected sepsis in low birthweight infants in India: a randomised controlled trial
What this study found
VSL#3 did not significantly reduce the primary fieldworker-diagnosed suspected sepsis outcome overall, but results were directionally favorable and a lighter-birthweight subgroup showed a clear benefit. Across all infants, suspected sepsis occurred in 84/668 (12.6%) with probiotic versus 107/672 (15.9%) with placebo, RR 0.79 (95% CI 0.56 to 1.03; p=0.080); incidence was 2.61 vs 3.40 per 1000 days, RR 0.77 (95% CI 0.59 to 0.99; p=0.0493). In infants weighing 1.5-1.99 kg, suspected sepsis was 4/74 (5.4%) versus 14/75 (18.7%), RR 0.29 (95% CI 0.10 to 0.84; p=0.014), with a lower incidence rate…
- Study & population
- Randomized, double-blind, placebo-controlled trial in low birthweight newborns in India, conducted at Safdarjung Hospital in New Delhi and the Mahatma Gandhi Institute of Medical Sciences in Wardha, with adjacent community follow-up.
- Intervention
- Infants in the active arm received VSL#3, an oral multi-strain probiotic powder, at 10 billion cfu per day for 30 days.
- Key limitation
- The primary outcome was not statistically significant, and several favorable findings came from subgroup or post hoc analyses, increasing the risk of chance findings.
Original abstract
Objectives To assess the effect of the probiotic VSL#3 in prevention of neonatal sepsis in low birthweight (LBW) infants. Design Randomised, double-blind, placebo-controlled trial. Setting Community setting in rural India. Participants LBW infants aged 3–7 days. Interventions Infants were randomised to receive probiotic (VSL#3, 10 billion colony-forming units (cfu)) or placebo for 30 days, and were followed up for 2 months. Main outcome measure Possible serious bacterial infection (PSBI) as per the Integrated Management of Neonatal Childhood Illnesses algorithm, as diagnosed by fieldworkers/physicians. Results 668 infants were randomised to VSL#3 and 672 to placebo. By intention-to-treat analysis, the risk of PSBI among infants in the overall population of LBW infants was not statistically significant (RR 0.79 (95% CI 0.56 to 1.03)). Probiotics reduced median days of hospitalisation (6 days vs 3 days in probiotics) (p=0.018) but not the risk of hospitalisation (RR 0.66 (95% CI 0.42 to 1.04). The onset of PSBI in 10% of infants occurred on the 40th day in the probiotics arm versus the 25th day in the control arm (p=0.063). Conclusions Daily supplementation of LBW infants with probiotics VSL#3 (10 billion cfu) for 30 days led to a non-significant 21% reduction in risk of neonatal sepsis. A larger study with sufficient power and a more specific primary end point is warranted to confirm the preventive effect of VSL#3 on neonatal sepsis in LBW infants. Trial registration number The study is registered at the Clinical Trial Registry of India (CTRI/2008/091/000049).
