Excerpt:
The concept that osteomalacia becomes progressively worse on chronic dialysis was reinforced by the findings in the repeat bone biopsies in that 6 of the 8 patients showed a significant increase in their osteoid index. . . . Thus, the progression of osteomalacia appears to be the main reason for the increasing incidence of bone pain and pseudofractures which we and others have observed in patients on chronic dialysis for periods longer than 6 months. Jowsey, et al, has reported similar findings. When the patients reported by Kim, et al. are classified in the same manner as ours were, a similar higher incidence of osteomalacia and absence of severe osteitis fibrosa was observed in patients on chronic dialysis for more than 6 months… The reason(s) for the progression of osteomalacia, which we observed in our chronic dialysis patients, remain(s) unclear. Factors which could result in impaired mineralization which must be considered include fluoride, hypermagnesemia, and phosphate depletion.

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

Bone disease in hemodialysis patients with particular reference to the effect of fluoride
Forty-one patients on our chronic hemodialysis program were assessed for the degree of progression of bone disease over an average period of 46 months. Seven patients were using a fluoridated dialysate. Four of these seven patients developed a marked increase in osteoid as judged by bone biopsy, while in the

Osteomalacia is associated with high bone fluoride content in dialysis patients
Osteomalacia is now rarely observed in hemodialyzed patients since the prevention of aluminum intoxication and vitamin D deficiency. However, this disorder is still present and may be responsible for bone fractures. Fluoride overload is responsible for mineralization defects. We therefore prospectively measured the bone fluoride content in all dialysis osteomalacic

Comparison of renal osteodystrophy in patients dialyzed with deionized and non-deionized water
Discussion There are 2 major types of osteodystrophy which occur in various combinations in dialysis patients. The first and most commonly predominant is secondary hyperparathyroidism. This appears to be preventable, or at least controllable, with a bath calcium concentration above 6 mg%. The second type is osteomalacia. In certain centers it

Fluoridation and bone disease in renal patients
About the Authors: William J Johnson, director of the Mayo Artificial Kidney Center and professor of medicine with the Division of Nephrology at the Mayo Clinic, has been involved in the study of calcium and phosphorus metabolism and renal osteodystrophy, potassium metabolism, and uremic neuropathy. He is past chairman of the Minnesota

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

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

Similarities between Skeletal Fluorosis and Renal Osteodystrophy
It is quite possible, and indeed likely, that some kidney patients diagnosed with renal osteodystrophy are either suffering from skeletal fluorosis or their condition is being complicated/exacerbated by fluoride exposure.

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.,

Mayo Clinic: Fluoridation & Bone Disease in Renal Patients
The available evidence suggests that some patients wtih long-term renal failure are being affected by drinking water with as little as 2 ppm fluoride. The finding of adverse effects in patients drinking water with 2 ppm of fluoride suggests that a few similar cases may be found in patients imbibing 1 ppm, especially if large volumes are consumed, or in heavy tea drinkers. The finding of adverse effects in patients drinking water with 2 ppm of fluoride suggests that a few similar cases may be found in patients imbibing 1 ppm, especially if large volumes are consumed, or in heavy tea drinkers and if fluoride is indeed the cause. It would seem prudent, therefore, to monitor the fluoride intake of patients with renal failure living in high fluoride areas.
