Clinical Trial Summary

Probiotics is suggested to play several roles in promoting health, including alleviating disease symptoms, protection against atopic disease, and modulating the immune system by improving the beneficial gut microbiota colonization. The discovery of the gut microbiota-brain axis suggested that there is a reciprocal influence between the brain and the gut through a constant communication. This bi-directional axis enables signals to be transferred from brain to influence sensory, motor, and secretory modalities of the GI tract, also permits signal from the gut to influence brain function. The establishment of intestinal microbiota during early neurodevelopmental period suggests the colonization and maturation of gut microbiota may influence brain development. Several studies have shown there is an association between shifts in the gut microbiota composition in children with neurodevelopmental disorders. This study aims to investigate how maternal probiotic + LC-PUFA supported with government program supplements, healthy eating, and psychosocial stimulation could affect fetal brain development and later child brain functions and cognitive development. Intervention would be delivered to pregnant women for 9 months, starting at the end of second trimester of gestational period.

Description:

Health and well-being at all ages is one of the goal set in the Sustainable Development Goals. Starting as early as possible has been considered to be an effective strategy for better investation in achieving healthy population. Therefore, the prevention and promotion of health and well being is starting to target population at younger age, starting as early as possible. Accordingly, the early life period of individuals has been considered as a critical period, especially in terms of the brain and cognitive development. The phases of brain development starts very early, starting from the fetal development in the uterus. The development process extends from early in the beginning of fetal development and lasted to the end, finishing last. The brain undergoes a period of rapid growth during the last trimester of fetal life and the first 2 years of childhood. Therefore, quality of pregnancy as well as quality of early life is important to the fetal brain development as well as later child brain function and cognitive development. In line with that notion, there are many studies suggesting that gut microbiota could affect CNS development through several ways, i.e. alteration of microbial composition, activation of immune system, changes in signaling via neural pathways, affecting tryptophan metabolism, modulating gut hormonal response and affecting hormonal signaling pathway, and releasing metabolites that could stimulate sympathetic nervous system. In particular, these studies have found bi-directional communication between the brain and the gut microbiota, referred to as the microbiota-gut-brain axis. The animal study showed that the gut microbiota regulates the development and function of the brain. Unfortunately, the study on human was still lacking.

This study is a randomized clinical trial (RCT) and placebo parallel controlled study, followed by a follow-up study at 2 years old. The research will be conducted in eight public hospitals / health care facilities in Indonesia, Jakarta.

In light of COVID-19 outbreak, if face-to-face activities are permitted by (1) national government (Indonesian Ministry of Health), (2) local government (DKI Jakarta), (3) the university, (4) Data Safety Monitoring Board, and (5) by consent of the subject, then the activities need to be strictly adjusted with the COVID-19 prevention measures for both personnel and subjects. All personnel and subjects who will be involved in the activities are required to fill out the COVID-19 symptom screening form prior to the visit.

Some adjustments for the project field implementation have been conducted during the outbreak, including:

1. Following Good Clinical Practice, for the safety of the subjects and all the team members, we are now ensuring that the subjects gain benefits from their involvement in the BRAVE project by implementing routine COVID-19 screening, providing adequate PPE for the fieldworkers, and educating them about the prevention measures.

2. Supplement delivery: Because we could not visit to the houses anymore due to staff restriction regulations, the bottles of the supplement are delivered using online motorcycle taxi services, and this includes the weighing scale for monthly monitoring. We have also developed a protocol to ensure the safety of supplement bottle transfer from the research personnel to the motorcycle taxi driver, and from the driver to the mothers, including safe distancing and disinfection procedures. We will also educate, provide a thermometer for self-temperature screening and provide the disinfectant to the mothers.

3. Outcome assessment: As per March 19, MRI assessment and blood sample collection remained implemented at a non-COVID-19 referral hospital and laboratory, with strict safety procedures for the subjects and personnel. For mothers who do not feel comfortable visiting the hospital/laboratory, they are free to refuse these procedures.

4. Compliance: Online system to promote and assess compliance. To maintain the quality, we cross-check mothers' activities by online assessment, interactive short message service (sms), and phone calls.

5. New Subject Recruitment are less priority right now or potentially stop for the time being until the situation is getting better.
