Abstract

Symptomatic osteodystrophy is uncommon in patients on RDT in Birmingham, it appears late and is associated with pronounced osteitus fibrosa. In Newcastle osteodystrophy is common and severe; it appears earlier and is associated with multiple fractures but not accompanied by radiological evidence of osteitis fibrosa. These differences cannot be explained by variations in exposure to fluoride but a pilot study suggests that some solute in the tap water may be responsible.

  • Serum ionic fluoride levels in haemodialysis and continuous ambulatory peritoneal dialysis patients

    High serum fluoride (F-) in patients with chronic renal failure (CRF) and end-stage renal disease (ESRD) is associated with risk of renal osteodystrophy and other bone changes. This study was done to determine F- in normal healthy controls and patients with ESRD on haemodialysis (HD) or peritoneal dialysis (PD). Seventeen

  • Renal osteodystrophy in patients on long-term hemodialysis with fluoridated water

    Serum and bone fluoride concentrations of ten patients maintained on long-term hemodialysis with fluoridated water (1 ppm, i.e., 50uM) were correlated with duration of treatment and the occurrence of clinical, radiological, and histological manifestations of bone disease. Two patients had symptomatic renal osteodystrophy when accepted on the program, whereas six

  • Fluoride metabolism and renal osteodystrophy in regular dialysis treatment

    Fluoride in plasma, urine and bone tissue ash were estimated using a fluoride-ion electrode in 20 control persons (CP), 32 patients with compensated chronic renal failure (CRFP) and 59 patients in RDT (RDTP). The increase in plasma fluoride (CP: 2.4 +/- 1.4, CRFP: 6.5 +/- 2.2, RDTP: 12.3 +/- 4.5

  • 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

  • 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

  • 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.

  • 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

  • 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.
