Air pollution is known to cause respiratory and cardiovascular diseases. But a new study shows that air pollution can also cause kidney damage. The findings, published in the June 30th issue of the Journal JASN, are calling for attention to the effects of air pollution on kidney disease.
Air pollution has become a serious problem in many cities in China, but the extent of its impact on health is unclear. In order to investigate the effect of air particles on kidney health, Dr. Hou Fan Fan from the Southern Medical University research team of 282 domestic city 938 hospitals in 71151 cases of patients with renal biopsy results were analyzed. The follow-up time of 11 years.
The results showed that the incidence of IgA nephropathy increased by 28.1% and the incidence of membranous nephropathy increased by 23.4% after age and region normalization. Membranous nephropathy can cause kidney failure - the corrected odds ratio increases by an average of 13% per year, and the risk of other major kidney diseases remains essentially unchanged. The incidence of membranous nephropathy is the highest in the air polluted area where the concentration of fine particles is high.
"The main finding of the study is that the incidence of membranous nephropathy in China has doubled in the past ten years," the researchers said. The increase of incidence is closely related to the distribution of air fine particles pollution area."
