Long-term ex­po­sure to air pol­lu­tion may not only lead to res­pi­ra­tory and car­dio­vas­cu­lar dis­eases, but also cause dam­age to the kid­neys, a new study has warned. To ex­am­ine how par­tic­u­late mat­ter in the air is af­fect­ing kid­ney health, re­searchers from South­ern Med­i­cal Uni­ver­sity in China an­a­lysed data on kid­ney biop­sies taken over 11 years from 71,151 pa­tients, en­com­pass­ing all age groups.

On av­er­age, the like­li­hood of de­vel­op­ing mem­bra­nous nephropa­thy, an im­mune disor­der of the kid­neys that can lead to kid­ney fail­ure, in­creased 13 per cent an­nu­ally over the 11-year study pe­riod, whereas the pro­por­tions of other ma­jor kid­ney con­di­tions re­mained sta­ble, re­searchers said.

Re­gions with high lev­els of fine par­tic­u­late air pol­lu­tion had the high­est rates of mem­bra­nous nephropa­thy, they said. “Our pri­mary find­ing is that the fre­quency of mem­bra­nous nephropa­thy has dou­bled over the last decade in China. We show that the in­crease cor­re­sponds closely with the re­gional dis­tri­bu­tion of par­tic­u­late air pol­lu­tion,” said Fan Hou from South­ern Med­i­cal Uni­ver­sity.
