Abstract

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 + 0.0343. The concentration in renal patients is about one-third of the one observed during F treatment for osteoporosis; it might therefore influence bone turnover. Fluoridated salt, tooth preparations and black tea were the main F sources in the patients studied.

  • 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,

  • Exposure to excessive fluoride during hemodialysis

    Discussion These data indicate that a patient maintained by hemodialysis in a community using fluoridated water may be exposed to a fluoride concentration higher than that present in tap water if the deionizer is allowed to become exhausted while the patient is being dialyzed. The concentration reached 520 uM in the

  • High fluoride exposure in hemodialysis patients

    The observation of higher plasma flouride levels in our hemodialysis (HD) patients than our continuous ambulatory peritoneal dialysis (CAPD) patients (4.0 +/- 0.5 mumol/L [n = 17] v 2.5 +/- 0.3 mumol/L [n = 17], P less than 0.005) prompted an evaluation of fluoride metabolism during HD. We found that

  • Studies on serum fluoride and bone metabolism in patients with long term hemodialysis

    With growing experience of the long-term treatment of patients with end stage renal disease by hemodialysis, the safety of fluoridated water supply for dialysate and the effect on the bone metabolism has been discussed. In this study, concentrations of fluoride (F), calcium (Ga). aluminum (AI) and biochemical indices of bone metabolism,

  • 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

  • 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

  • Skeletal Fluorosis in the U.S.

    Although there has been a notable absence of systematic studies on skeletal fluorosis in the U.S., the available evidence indicates that the consumption of artificially fluoridated water is likely to cause skeletal fluorosis and other forms of bone disease in people with kidney disease and other vulnerable populations.

  • Exposure Pathways Linked to Skeletal Fluorosis

    Excessive fluoride exposure from any source -- and from all sources combined -- can cause skeletal fluorosis. Some exposure pathways , however, have been specifically identified as placing individuals at risk of skeletal fluorosis. These exposure pathways include: Fluoridated Water for Kidney Patients Excessive Tea Consumption High-Fluoride Well Water Industrial Fluoride Exposure Fluorinated Pharmaceuticals (Voriconazole

  • 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.
