Abstract
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, with a significant decrease in the averages. Furthermore, there is a highly significant correlation between fluoride levels before and after the dialysis session (P < 0.00001), and also between the amount of time in hemodialysis (in months) and the average fluoride level before dialysis (r = 0.624; P = 0.008). The presence of a group of patients consuming fluoride waters such as Vichy St-Yorre Water was easily identified by their excessive fluoride levels (above 100 micrograms/l), which could have a tendency to increase the risks of this group.

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 +

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

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

Serum and urine fluoride concentration: relationships to age, sex and renal function in a non-fluoridated population
Serum and urine fluoride levels were determined in 250 healthy subjects (15-90 years, 122 men and 128 women) residing in Catalonia, Spain, and in 150 patients (20-81 years, 84 men and 66 women) with chronic renal failure undergoing regular dialysis treatment, living in the same geographical area, to determine normal

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

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.

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

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
