Fine particle air pollution detrimental to kidney health
A new study has found that exposure to higher amounts of fine particulate matter was associated with a higher degree of albuminuria and a higher risk of developing chronic kidney disease over time.
Washington: There is no denial of the fact that breathing in air pollution can have detrimental health effects beyond the lungs, but few studies have shown how it impacts the kidneys.
Researchers conducted a study to find relationship between long-term PM2.5 exposure and kidney disease, level of albuminuria, and incident CKD. They found that people living in areas with higher levels of air pollution faced higher risks of developing kidney disease. The findings appear in an upcoming issue of CJASN.
To investigate, Matthew F. Blum, MD (Johns Hopkins University School of Medicine) and his colleagues examined information on 10,997 adults across 4 sites in the United States who were followed from 1996-1998 through 2016. The researchers estimated the monthly average levels of tiny particles of air pollution--called fine particulate matter--based on participants' home addresses. Fine particulate matter comes from a variety of sources including fossil fuel combustion, industrial processes, and natural sources.

The team found that exposure to higher amounts of fine particulate matter was associated with a higher degree of albuminuria--a marker of kidney dysfunction--at the start of the study as well as a higher risk of developing chronic kidney disease over time.
"As rates of chronic kidney disease rise worldwide, it is important to understand whether and how exposure to air pollution plays a role," said Dr. Blum.
The authors noted that their findings may be especially important for parts of the world with higher air pollution, such as China and India, where fine particulate matter levels are 5 to 10 times higher than in the United States. Future studies should examine whether efforts to improve air quality yield health benefits, including reducing rates of chronic kidney disease.
