Protective effect of probiotics shown to last at least two years

Researchers at the Wellington Asthma Research Group, Wellington School of Medicine and Health Sciences, University of Otago, Wellington, New Zealand, have carried out a study on 425 infants to show that the protective effect of Lactobacillus rhamnosus HN001 (HN001), when given for the first two years of life, lasts for at least another two years of life.

The infants were from a high risk birth cohort, and the mothers were supplemented with either HN001 or Bifidobacterium animalis subsp lactis (HN019) from 35 weeks gestation until 6 months if breastfeeding, and until 2 years of age. Supplementation with HN0001 halved the cumulative prevalence of eczema by age 2, whereas HN019 had no effect.

The findings also showed a protective effect against rhinoconjunctivitis, suggesting that HN001 might be an appropriate preventative intervention for high risk atopic children.
