NCT05923333

Brief Summary

The primary objectives of this study are to evaluate the effect of early-life B. infantis Rosell®-33 supplementation in infants exposed to HIV on:

  • gut microbiome composition and diversity at 4 weeks of life
  • markers of intestinal inflammation and microbial translocation at 4 weeks of life
  • Th1 cytokine responses to BCG at 7 weeks and 36 weeks of life The secondary objectives include to evaluate the effect of B. infantis Rosell®-33 supplementation on:
  • longitudinal succession of the gut microbiota composition, diversity and function
  • relative and absolute abundance of B. infantis in infant stool during the first 36 weeks of life
  • stool metabolome
  • T cell subset ontogeny during the first 9 months of life. Exploratory objectives are to evaluate whether B. infantis Rosell®-33 supplementation improves:
  • infant growth
  • all-cause morbidity
  • neurodevelopment during the first 9 months of life
  • antibody responses to early childhood vaccines

Outcome Measures

Primary Outcomes (4)

  • Gut microbiome

    Alpha (Shannon) and Beta (Bray Curtis and UniFrac) diversity metrics on the entire microbial communities, assessed by bacterial shotgun metagenomics of infant stool, will be compared between treatment arms

    4 weeks of age

  • Markers of intestinal inflammation and microbial translocation

    Concentration of markers of intestinal inflammation and microbial translocation (Lipocalin-2 (Lcn-2), sCD163, I-FABP and LBP measured by ELISA in infant plasma) will be compared cross-sectionally at each time point between groups using Mann-Whitney U tests

    4 - 36 weeks of age

  • BCG vaccine respone

    Frequencies of total net cytokine producing cells in response to stimulation with BCG will be compared between arms.

    7 weeks of age

  • BCG vaccine respone

    Frequencies of total net cytokine producing cells in response to stimulation with BCG will be compared between arms.

    36 weeks of age

Secondary Outcomes (3)

  • Longitudinal succession in gut microbiota composition, diversity and function

    4 - 36 weeks of age

  • Stool metabolome

    4 weeks of age

  • T cell subsets frequencies

    4 - 36 weeks of age

Other Outcomes (5)

  • Presence of total B. infantis and B. infantis Rosell®-33 in stool

    4 - 36 weeks of age

  • Infant neurodevelopment milestones

    24 and 36 weeks of age

  • Infant growth

    4 - 36 weeks of age

  • +2 more other outcomes

Eligibility Criteria

Age0 Days - 50 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Willing and able to provide signed and dated informed consent form
  • years of age or older
  • Documented HIV seropositive
  • Antiretroviral therapy initiated before the third trimester of pregnancy
  • Planning on exclusively breastfeeding the infant for the first 6 months of life
  • Documented HIV seronegative at birth
  • Born at term (completed at least 37 weeks of gestation)
  • Birth weight \>2.4kgs

You may not qualify if:

  • Severe illnesses, e.g. Sepsis
  • current TB or known household TB contact
  • Chronic disorder or medications (other than antiretrovirals and cotrimoxazole prophylaxis) that in the opinion of the investigator would alter immunity
  • Pregnancy or delivery complications including birth asphyxia, seizures, sepsis, major congenital anomalies or congenital infections
  • Known contraindications to components of the interventional products
  • Taking additional probiotics or prebiotics
  • Any condition that in the opinion of the investigator would make participation in the trial unsafe
