Abstract
In order to observe the consequences of chronic ingestion of high fluoride-rich water on plasma potassium levels of hemodialysed subjects, we have conducted a retrospective study on 25 patients with chronic renal failure, treated with a substitute method, six of whom (consumers group, group C) were drinkers of a bicarbonate (about 4500 mg/l) and fluoride-rich (9 mg/l) mineral water, the Vichy Saint-Yorre water. With respect to sodium polystyrene sulfonate consumption (n = 17), there was no significant difference between group C and NC (non-consumers group). A significant correlation between plasma fluoride and potassium levels was observed only before dialysis (P < 1 x 10(-7)) but not after dialysis. A group by group analysis revealed that this correlation was linked to group C (P < 5 x 10(-6)), in which kalemia before dialysis was higher than that observed in group NC (P < 0.005). Moreover, it appeared that the higher fluoride levels were, the higher the kalemia was inclined to be. Thus, the risks of hyperkalemia in dialysed patients, who also drink Vichy St-Yorre water or other fluoride-rich waters, are more important, while not forgetting the risk of fluorosis. The mechanisms by which chronically administered fluoride could increase kalemia are also discussed.

Serum fluoride concentrations in renal insufficiency
In an area with non-fluoridated water (F content, 0.061 ppm), serum fluoride concentrations as measured with an ion specific electrode were as follows: controls (N = 13), 0.0127 ppm + 0.0057 (mean + SD); renal insufficiency (N = 10), 0.0452 ppm + 0.0151; chronic hemodialysis (N = 11), 0.0424 +

Long-term follow up of ionic plasma fluoride level in patients receiving hemodialysis treatment
The elimination half-life of fluoride is significantly increased in patients with chronic renal failure. This led us to conduct a study of variations of its plasma levels in 35 patients receiving dialysis treatment. In this population, there is a gaussian distribution of the values before and after the hemodialysis session,

Effects of fluoride on bone metabolism in patients with hemodialysis
The maior pathway of fluoride elimination from the human body is the kidney. The discharge of fluoride into urine depends on the clearance of the kidney. Fluoride in serum of hemodialysis patients is higher than that of healthy subjects. Fluoride is not reduced sufficiently with hemodialysis. Those patients are in

Association between fluoride, magnesium, aluminum and bone quality in renal osteodystrophy
INTRODUCTION: Trace elements are known to influence bone metabolism; however, their effects may be exacerbated in renal failure because dialysis patients are unable to excrete excess elements properly. Our study correlated bone quality in dialysis patients with levels of bone fluoride, magnesium, and aluminum. A number of studies have linked

Pattern of renal osteodystrophy in haemodialysis patients in Saudi Arabia
In order to know the pattern of renal osteodystrophy in haemodialysis patients in Saudi Arabia we conducted a multicentre study involving 209 patients. The mean age of the patients was 39.4 +/- 14 (18-70) years, 128 were males and 81 females. All patients were on acetate dialysate and their mean

Fluoride & Osteomalacia
One of fluoride's most well-defined effects on bone tissue is it's ability to increase the osteoid content of bone. Osteoid is unmineralized bone tissue. When bones have too much of it, they become soft and prone to fracture -- a condition known as osteomalacia. As shown below, fluoride has repeatedly been

Dental Fluorosis & Enamel Hypoplasia in Children with Kidney Disease
Children with kidney disease are known to have high levels of fluoride in their blood and to be at risk for disfiguring tooth defects. Research suggests that high levels of fluoride in blood, which can cause the tooth defect known as dental fluorosis, can contribute to the defects that occur

Kidney Patients Are at Increased Risk of Fluoride Poisoning
It is well established that individuals with kidney disease are susceptible to suffering bone damage and other ill effects from low levels of fluoride exposure. Kidney patients are at elevated risk because when kidneys are damaged they are unable to efficiently excrete fluoride from the body. As a result, kidney patients

Fluoridation, Dialysis & Osteomalacia
In the 1960s and 1970s, doctors discovered that patients receiving kidney dialysis were accumulating very high levels of fluoride in their bones and blood, and that this exposure was associated with severe forms of osteomalacia, a bone-softening disease that leads to weak bones and often excruciating bone pain. Based on

Unheeded Warnings: Government Health Authorities Ignore Fluoride Risk for Kidney Patients
Despite the well known fact that individuals with kidney disease are at much higher risk of fluoride toxicity than the general population, there has yet to be any attempt in the United States, or any other country that practices mass-scale water fluoridation to determine the prevalence of fluoride-related effects (e.g.,
