About this study

Official title: Multicenter, Randomized, Double-blind, Controlled Parallel Nutritional Intervention Study to Evaluate the Effect of Consumption During Pregnancy and the Lactation Period of Lactobacillus Fermentum CECT5716 on the Incidence of Mastitis

The aim of the present study is to evaluate the effect of consumption during pregnancy and the lactation period of the probiotic L. fermentum CECT5716 on the incidence of mastitis.

Bacterial load and immunological parameters in breast milk, parameters related to breastfeeding as well as health parameters of the mother and baby will also be evaluated.

Read the detailed description

Pregnancy and lactation are important moments for the child that will determine their development and future health. One of the key processes is when the microbiota is established in the baby. Contamination during delivery with the mother's vaginal flora, as well as bacteria from the microbiota of breast milk, are important sources for intestinal colonization. However, the mother's microbiota can suffer alterations that affect the health of the mother and can also have an effect on the baby.

Mastitis is a condition of the mammary gland that can affect between 3-30% of women during the period of lactation and is the first cause of abandonment of it. It is associated with a dysbiosis with the proliferation of microorganisms in milk such as Staphylococcus and Streptococcus.

Previous studies carried out with the strain L. fermentum CECT5716 have demonstrated a powerful regulating activity of the microbiota of breast milk that translates into a preventive and curative effect on mastitis. The highest incidence of mastitis occurs during the first weeks after delivery, so the investigator's working hypothesis is that the modulation of the maternal microbiota before delivery would improve the effectiveness of the probiotic strain consumption.

Questions about this trial

What is this clinical trial studying?

A study testing Lactobacillus fermentum CECT5716 and Maltodextrin in people with Mastitis and Breast Milk, run by Biosearch S.A. at 3 sites in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Where is the study taking place?

The record lists 3 sites in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04032899, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Feb 2025.
