About
Primary Objective:
- To evaluate the effects of synbiotics on infectious morbidity and growth while it is in place from 4 to 24 weeks of age.
- To evaluate the effects of synbiotics on infectious morbidity and growth from 4 to 48 weeks of age.
Secondary Objectives:
- To evaluate the effects of synbiotics on growth from 4 to 72 weeks of age.
- To evaluate the effects of synbiotics on infant neurodevelopment at 48 and 72 weeks of age.
- To evaluate the effects of synbiotics on biological measurements while it is in place from 4 to 24 weeks of age.
- To evaluate the effects of synbiotics on biological measurements from 4 to 48 weeks of age.
- To evaluate the effects of synbiotics on gut microbiome and fecal short chain fatty acids from 4 to 72 weeks of age.
- To investigate feasibility, acceptance, tolerability, and behavioral adherence with the intervention.
- To investigate whether the synbiotics reduces infectious morbidity and improves growth in CHEU relative to CHUU.
- To investigate whether infant gut microbiota composition, maturity and function, and markers of inflammation and HMOs at baseline and over time are associated with morbidity and poor growth in CHEU and CHUU.
Full description
Children who are HIV-exposed uninfected (CHEU), i.e., children born to mothers with HIV but who do not acquire HIV infection, have a higher risk of mortality, infectious morbidity, and growth deficits than children who are HIV-unexposed uninfected (CHUU), i.e., children whose mothers do not have HIV. Prior research has focused on breastfeeding and has pointed to changes in human milk oligosaccharides (HMOs) associated with maternal HIV infection that appear to influence the infant microbiome and thereby lead to these adverse outcomes. A randomized trial of an intervention which combines HMOs and probiotics in breastfed CHEU will be conducted in South Africa to evaluate whether this intervention has the potential to reduce excess infectious morbidity and growth faltering risks observed in CHEU. CHEU will be randomized 1:1 to either a) intervention (synbiotic: 2'-FL HMO + B. infantis probiotic) or b) placebo (Maltodextrin). The study intervention or placebo will be given from 4-24 weeks of age (total 20 weeks), followed by another 48 weeks of observation off study treatment. Both arms will be followed to 72 weeks of age for assessment of infant outcomes.

For HIV-exposed uninfected children (CHEU): Mothers living with HIV documented based on medical record and with viral suppression (i.e., <400 copies/mL viral load) documented at delivery
-
For HIV-unexposed uninfected children (CHUU): Mothers without HIV (document HIV-negative test result at delivery or screening)
-
Women who initiated breastfeeding of their infant including:
- Women who currently exclusively breastfeed their infants, or
- Women who breastfed their infants for a period but are no longer breastfeeding, or
- Women who are currently breastfeeding their infants in addition to feeding them formula milk or solids
-
For women with HIV: Those currently on first-line standard of care antiretroviral therapy that was initiated a minimum of 12 weeks prior to delivery of the infant included in this study
-
Participant has a cell phone that can be used for calls and messages
-
Agreement to adhere to Lifestyle Considerations throughout study duration
Inclusion Criteria for Children:
- 3-6 weeks of age
- Delivered from a singleton pregnancy
- For children of mothers with HIV: At least one HIV diagnostic nucleic acid amplification test prior to enrollment which is negative and no positive test
- Child is well enough to have established full breastfeeding by the time of enrollment
Exclusion Criteria:
- Severe maternal or infant illness (e.g., maternal: tuberculosis, major psychiatric or neurological conditions; infant: any congenitally-acquired infections, major congenital anomalies)
- Use of immunomodulatory or immunosuppressive drugs in either mother or child prior to enrollment in the study
- For mothers with HIV: Mothers who are not currently receiving antiretroviral therapy or who are on regimens other than the currently recommended first-line standard of care in South Africa i.e., first-line dolutegravir- or efavirenz-based regimens.
- Children infected with HIV
- Mother or infant currently taking probiotics, prebiotics, or fiber supplements; or on any nutritional supplements (e.g., FM85) that impact the outcomes of interest
- Mother or infant currently taking antibiotics for more than 14 days, excluding preventative therapies
- Known allergic reactions to components of the treatment or placebo
- Any condition that, in the opinion of the study staff, would make participation in the study unsafe, complicate interpretation of study outcome data, or otherwise interfere with achieving the aims of the study.
