Endocrine disruptors: Can it be the missing link explaining the diabetes epidemic in India?

Abstract

India is the diabetes capital of the world with an exponential increase in diabetes prevalence in the last few decades. It may not be just a simple co-incidence that the global increase in diabetes is associated with an exponential increase in industrial chemical output. Literature searches through PubMed, Medline and Embase for articles published until July 2014 evaluating link between endocrine disrupting chemicals (EDCs) and diabetes was done. This review observed that a large volume of data is available from preclinical studies implicating commonly used synthetic compounds in the pathogenesis of diabetes. EDCs have been demonstrated to interact with almost all the steps of insulin homeostasis starting from its synthesis to its signaling and action. Bisphenol-A, 2,3,7,8-tetrachlorod-ibenzo-dioxin (TCDD)/dioxin, polychlorinated biphenyls (PCBs), persistent organic pollutants, diethylhexylphthalate, cadmium and arsenic are some of the important EDCs which interfere with a maximal number of pathways of insulin homeostasis. However data from humans establishing the causality lacks from across the globe, with maximal data available from bisphenol-A and TCDD from USA. Their evaluation among Indians, especially with regards to dysglycemia, insulin resistance and beta cell function is non-existent, thus warranting urgent research in this area.
