Dear Nicson,
I don't know if this article is of any interest? I'm not in Medicine, and please don't accept these views
as being valuable in any way. But interesting in any case, the Nephrologist I see is very good and sympathetic, but there seems to be limited amounts that can be achieved with this condition.

MADRID — A lethal epidemic of chronic kidney disease not associated with any of the usual risk factors, such as hypertension and diabetes, is claiming the lives of relatively young men who work outdoors in hot spots around the world, and some experts are blaming the phenomenon on long hours spent in high temperatures without proper rehydration.
An estimated 50,000 people have already died, Richard Johnson, MD, from the University of Colorado Hospital in Aurora, reported at the European Renal Association and European Dialysis and Transplant Association 54th Congress.
From the podium in Madrid, Dr Johnson questioned whether "global warming and water shortage" might be contributing to the problem.
"Of course, it's possible that toxins are involved, but we now think that the disease might be driven by repeated bouts of acute injury to the kidney," he told Medscape Medical News.
"Over time, this worsens kidney function, and patients can then develop classical signs of kidney failure with nausea, poor appetite, and high blood pressure," he explained. "And since dialysis is rarely available in these areas, the disease can progress, leading to death."
One of the hardest-hit areas is Central America, where it is estimated that 20,000 people working in sugarcane fields have died from kidney failure.
In Central America, the illness has been dubbed Mesoamerican nephropathy. It is also referred to as heat stress nephropathy and chronic kidney disease of unknown etiology.Most strikingly, the disease does not appear to be due to any of the common causes of end-stage renal disease.Dr Johnson described a mouse model of recurrent dehydration that he and his colleagues developed to study the possible mechanism for the disease (Kidney Int. 2014;86:294-302).

Typically, young men present with an asymptomatic rise in serum creatinine in association with low-grade or no proteinuria, explained Carlos Roncal-Jimenez, MS, from the University of Colorado Denver in Aurora.
