Clostridium difficile infection is an intestinal infection that can be life threatening. The incidence is increasing in children, and there is resistance to standard treatment with rising rates of recurrence. In resistant and recurrent cases, manipulation of the microbiome by FMT is an effective treatment. We are examining the intestinal microbiome in children before and after FMT. The goal is to gain a better understanding of why this treatment is effective and also to improve FMT treatment for children in the future.
The contribution of antibiotic exposure in the prenatal, peripartum and infancy period to intestinal microbiome perturbations and association with early childhood obesity.
There is accumulating evidence that early life exposure to antibiotics increases the risk for obesity. It is hypothesized, but has never been shown, that this is due to antibiotics causing detrimental gut microbiota disturbances that “program” the host to an obesity-prone metabolism. This research study aims to determine the relative contributions of antibiotic exposure in the prenatal, peripartum and infancy period to intestinal microbiome disturbances and association with early childhood obesity. Babies are followed from birth until 2 years of age with serial stool collections and survey assessments of their health. The results of this study, with identification of the critical time period of antibiotic exposure as a risk for obesity, would allow for several strategies for reducing the risk of obesity later in life.
