Climate change causing dehydration and heat stress may be accelerating rates of chronic kidney disease according to research appearing in an upcoming issue of the Clinical Journal of the American Society of Nephrology (CJASN). The findings suggest that a condition called heat stress nephropathy may represent a disease of neglected populations, but one that may emerge as a major cause of poor kidney health in the near future.
Over the next century, climate change and resulting water shortages are likely to affect a wide variety of health issues related to dehydration and heat stress-with risks increasing for cognitive dysfunction, malnutrition, water-borne infectious diseases, chronic kidney disease, and other conditions.
A team led by Richard Johnson, MD, Jay Lemery, MD (University of Colorado School of Medicine), and Jason Glaser (La Isla Foundation) sought to describe reports of heat stress nephropathy-or chronic kidney disease consistent with heat stress-that are already occurring throughout the world.
The researchers recommend that governments and scientists work together to conduct epidemiological and clinical studies to document the presence of these epidemics and their magnitude. Interventions are also needed to improve worksite conditions and ensure adequate hydration.
"We were able to connect increased rates of chronic kidney disease in different areas to an underlying mechanism-heat stress and dehydration-and to climate," said Dr. Johnson. "A new type of kidney disease, occurring throughout the world in hot areas, is linked with temperature and climate and may be one of the first epidemics due to global warming."
