Trial summary

Preterm birth (PTB) occurs before 37 weeks of gestation and is a major cause of neonatal mortality and morbidity. PTB results from heterogeneous influences. One of them is the inherited predisposition of spontaneous PTB, and another is the change in the placental microbial composition as this can cause infections… Read more about this study

About this study

Official title: Molecular Signature of Karen and Burmese Children Until Two Years of Age on the Thailand--Myanmar Border: a Study Extension of TMEC 15-062

Preterm birth (PTB) occurs before 37 weeks of gestation and is a major cause of neonatal mortality and morbidity. PTB results from heterogeneous influences. One of them is the inherited predisposition of spontaneous PTB, and another is the change in the placental microbial composition as this can cause infections, which lead to inflammation, a common cause of preterm birth. Interestingly, maternal periodontal disease is an independent risk factor for PTB, low birth weight and fetal growth restriction. Immune responses to infectious events or inflammation as well as genetic predisposition to inherited conditions have successfully been studied by using assessing genetic expression profiling. The molecular signature is sets of genes, proteins, genetic variants or other variables that can be used as markers for a particular phenotype.

Child morbidity from malnutrition resulting in poor growth and stunting remains a major public health issue that affects the local population just like PTB. While risk factors for malnutrition are multifaceted, there is also a hypothesized causal link between early gut microbiome disruption that leads to chronic malnutrition in otherwise healthy infants.

Molecular signatures including the intestinal microbiome development of preterm infants will be evaluated and compared to the term (≥37 weeks' gestation) counterparts. Moreover, a comprehensive examination of possible factors associated with poor growth and poor motor- and neurodevelopment will be assessed.

In this extension study: The primary goal for the child is to evaluate the perturbation in the development of the genomic profile including intestinal microbial habitat from children in a rural and limited-resource setting from birth to two years of life.

Read the detailed description

Rationale:

The importance of early life epigenetics is now recognized to have direct implications for health in later life and a consistent limitation expressed in peer reviewed publications has been the small sample size of the studies. Rather than establish a separate cohort to study epigenetics in young children in this environment this extension study of TMEC 15-062 (Molecular signature of Karen and Burmese women on the Thailand--Myanmar border) aims to build on the detailed sampling of the mothers to not only identify biomarkers of preterm labor but also to understand high rates of stunting and anaemia in this area, and possibly develop predictive tools or pave new ways for prevention in the future.

Moreover, a non-invasive intervention in the form of nutrition and WASH counselling may provide information on whether this form of engagement can positively influence child development, prevent malnutrition and whether perturbations in the infants molecular signature can be observed.

In addition, the mothers exposed to the sampling procedure at birth in this study will be able to make a well-informed decision about whether they wish to enrol the child in such a study.

The rationale for the planned samples in children born to mothers who participated in the TMEC 15-062 study are summarized in the following text:

Child gut microbiome and assessment of nutrition from stool samples (Risk-none) The intestinal ecosystem is very dynamic, especially in the first period of life, as it needs to evolve from scratch, hence investigators want to follow children and analyse stool samples in first 24 month of life. investigators propose to assess what kind of impact the gut microbiome has on the child's growth and development. Since exposure to helminths is common in the study population, children stool samples will also be used to examine for helminthic infestations.

This point would also include a home visit as part of nutrition evaluation by questionnaire and direct observation (food preparation including hygiene, child food content, feeding patterns) to relate to microbiome.

Early childhood Transcriptome from capillary blood (Risk-minimum) This point will enable us to understand whether preterm infants have different gene expression than their term counterparts and if so, how it evolves in the early period of life. Moreover, specific signals for children at risk for or suffering from malnutrition or stunting resulting from gastrointestinal inflammation or barrier disruption could be picked up. Total blood 0.85 mL in 2 years.

Early childhood detection of anaemia from capillary blood (Risk-minimum) Anaemia will be treated and iron supplement effect on gut microbiome analysed. Total blood 0.85 mL in 2 years.

Early childhood detection of soil transmitted helminth infection from stool sample (Risk-none) Helminth infection will be treated and the effect on gut microbiome analysed. Stool sample each visit.

Child growth assessment and evaluation of motor and neurocognitive development (Risk-none) Premature infants have a higher risk for lifelong health and development problems. Investigators propose to follow the children's over the period of 2 years to assess their growth and their neurocognitive and motor development. Preterm children's growth and development will be compared to term neonates. The recommended schedule of growth assessment in healthy children is (1, 2, 4, 6, 9, 12, 18, 24 months). In this study children will be followed more frequently: monthly in the first year of life and 3 monthly in the 2nd year of life (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 15, 18, 21, 24 months). The reasons for this include: the objective of the root study TMEC 15-062 which is on preterm infants who require closer follow up, to relate perturbations of biomarkers to stunting, and in this mobile population scheduled visits may be missed so a more flexible arrangement for checking anthropometry at any monthly visit in the first year of life reduces the chance that poor growth is not identified.

In addition, the growth and development of children born to mothers who had a febrile episode during pregnancy will be compared to children whose mothers did not experience fever episodes during pregnancy.

Children with poor growth or malnutrition will be given supplementary nutrition and nutrition advice will be given to the mother.
