Study summary

To evaluate the effect of the consumption of Lactobacillus fermentum CECT5716 on mastitis incidence.

Read the detailed description

Previous studies have demonstrated that L. fermentum CECT5716, a probiotic strain previously isolated from breast milk, can be used as an effective treatment of mastitis and painful breastfeeding by reducing pathogen counts in breast milk. This is a randomized double blinded controlled study to evaluate the effect of L.fermentum CECT5716 on mastitis incidence and Staphylococcus load in breast milk. Women will be recruited 1-6 days after child birth and distributed into two groups: Probiotic group receiving 1 capsule/day containing L.fermentum 3x109cfu; Control group receiving 1 placebo capsule/day containing maltodextrin. The intervention period is 16 weeks.

What researchers measure

Primary outcomes

  1. incidence of mastitis

    mastitis was defined as at least two out of the three breast symptoms (pain, redness, lump) and at least one of fever or flu-like symptoms (shivering, hot sweats or aches)

    Time frame: up to 16 weeks

Secondary outcomes

  1. evaluation of breast pain

    For pain evaluation a score from 1 (no pain) to 10 (extremely pain)

    Time frame: at times 0, 4, 8, 12 and 16 weeks

Other outcomes

  1. microbiota breast milk

    DNA will be extracted from breast milk samples. Staphylococcus genus, Streptococcus and Lactobacillus will be evaluated by qPCR with specific probes designed to quantify these bacterial genus.

    Time frame: at time 0 and 16 weeks

  2. fecal microbiota of infants

    DNA will be extracted from infant´s feces samples. Lactobacillus, bifidobacterium, clostridium, bacteroides will be evaluated by qPCR with specific probes designed to quantify these bacterial genus.

    Time frame: at 0 and 16 weeks

  3. growth of infants

    Weight, length and head circumference will be measured in infants at the beginning and at 16 weeks

    Time frame: at 0 and 16 weeeks
