Study Objectives: Investigate the efficacy of L. reuteri DSM 17938 for the treatment of infant colic in breastfed infants ≤ 6 months.

Study Design: R, DB, PC, 21 days

Subjects and daily dose: 24 patients L. reuteri DSM 17938 (1x10⁸ CFU), 28 patients Placebo

Results:

Compared to placebo:

• L. reuteri significantly improved colic symptoms by reducing median crying and fussing times at days 7, 14 and 21.
• The rate of responders (50% reduction in daily crying time) was significantly higher in the L. reuteri group compared with the control group at day 21.

Study Objectives: Evaluate the effects of L. reuteri DSM 17938 on colicky infants < 4 months old, exclusively or predominantly breastfed: on rate of treatment success, reduction in daily crying time, parent satisfaction and maternal depression.

Study Design: R, DB, PC, 4 weeks

• Improved maternal depression scores throughout the study period (Edinburgh postnatal depression scale).
• No report of adverse effects in any of the groups.

Une étude randomisée, en triple aveugle, contrôlée par placebo avec L. reuteri DSM 17938 a montré une augmentation des titres d'anticorps contre le SRAS-CoV-2 chez les volontaires sains après un délai de 28 jours ou plus après la vaccination. L'étude suggère que la supplémentation en probiotiques peut augmenter la protection à long terme contre les infections virales.

L'étude a inclus 159 adultes en bonne santé n'ayant jamais été infectés par le SRAS-CoV-2 et n'ayant jamais été vaccinés contre le COVID-19. Les participants ont consommé L. reuteri DSM 17938 + 10 microgrammes de vitamine D3, ou un produit placebo contenant uniquement de la vitamine D3 pendant 6 mois. Pendant la période d'intervention, 12 sujets ont été infectés et 17 ont été complètement vaccinés.

L'objectif de l'étude était d'examiner l'effet de la supplémentation en L. reuteri DSM 17938 sur les réponses des anticorps spécifiques au SRAS-CoV-2 après une infection naturelle ou une vaccination. Bien que le résultat principal, basé sur les sujets infectés, n'ait pas atteint de différence statistiquement significative entre les deux groupes, les individus vaccinés prenant L. reuteri DSM 17938 ont montré des niveaux d'anticorps IgA significativement plus élevés 28 jours ou plus après la vaccination par rapport au groupe placebo.

L'étude a été menée au Centre de recherche sur les interactions Nutrition-Intestin-Cerveau de l'Université d'Örebro, en Suède.

"À notre connaissance, il s'agit de la première étude à examiner l'effet d’une supplémentation en probiotiques sur les différentes classes d'anticorps contre le SRAS-CoV-2, y compris les anticorps neutralisant le virus, dans une cohorte naïve en anticorps", déclare le Professeur Robert Brummer, l'un des chercheurs auteurs de l'étude.

Les résultats suggèrent que L. reuteri DSM 17938 peut améliorer la protection à long terme contre les infections virales après la vaccination.

Il a été démontré que les probiotiques protègent contre les infections des voies respiratoires¹ et augmentent l'efficacité de certaines vaccinations.² Une étude clinique antérieure a montré que L. reuteri DSM 17938 réduisait l'absentéisme au travail dû à des infections courantes.³

Study Objectives: To investigate milk with low and regular calcium content, respectively, and the addition of probiotics (L. reuteri DSM 17938 or L. casei CRL431) to milk with regular calcium content, on the incidence and duration of diarrhoea and acute respiratory infections in healthy Indonesian children, 1-6y old.
