Les reins : cibles du réchauffement climatique ? [The kidneys : possible victims of global warming ?]

Over the last decades, an increasing number of cases of chronic and end-stage kidney disease has been observed in Central America and Asia. This kidney disease mainly affects young farmers without classic renal risk factors. The clinical presentation includes a progressive decrease of the glomerular filtration rate, minimal proteinuria and the presence of tubulo-interstitial nephritis at renal biopsy. A close link with global warming is suspected for this disease, called (according to its location) meso-american nephropathy, Sri Lanka nephropathy or chronic kidney disease of unknown etiology. Others have suggested that intake of water contaminated with pesticides may be responsible. This article provides an overview of this new kidney disease. Measures to prevent acute kidney injury during heat waves in Switzerland are also discussed.
