A comprehensive review by a Texas Tech University Health Sciences Center (TTUHSC) El Paso internal medicine resident and a nephrologist on the association between environmental exposures, poverty, and disparities in kidney disease has been published in the January 2015 issue of the journal Advances in Chronic Kidney Disease (ACKD).
Sarmad Said, M.D., a third-year resident, and German Hernandez, M.D., associate professor in the Division of Nephrology & Hypertension, Department of Internal Medicine, TTUHSC El Paso titled their publication “Environmental Exposures, Socioeconomics, Disparities, and the Kidneys”.
Abstract for the study is as follows:
Kidney disease disproportionately affects racial and ethnic minority populations, the poor, and the socially disadvantaged. The excess risk of kidney disease among minority and disadvantaged populations can only be partially explained by an excess of diabetes, hypertension, and poor access to preventive care. Disparities in the environmental exposure to nephrotoxicants have been documented in minority and disadvantaged populations and may explain some of the excess risk of kidney disease. High-level environmental and occupational exposure to lead, cadmium, and mercury are known to cause specific nephropathies. However, there is growing evidence that low-level exposures to heavy metals may contribute to the development of CKD and its progression. In this article, we summarize the excess risk of environmental exposures among minority and disadvantaged populations. We also review the epidemiologic and clinical data linking low-level environmental exposure to lead, cadmium, and mercury to CKD and its progression. Finally, we briefly describe Mesoamerican nephropathy, an epidemic of CKD affecting young men in Central America, which may have occupational and environmental exposures contributing to its development.
