Abstract

Two patients had a combination of renal insufficiency and systemic fluorosis. One had bilateral vesicoureteral reflux and recurrent pyelonephritis, with resulting renal atrophy; the other had probable renal dysgenesis of indeterminate origin. Both patients had polydipsia, polyuria, and markedly reduced renal function. Both also had clinical and roentgenographic evidence of systemic fluorosis. It is postulated that the renal insufficiency which resulted in the large intake of fluoride-containing water and reduced excretion of fluoride combined to produce systemic fluorosis.

Excerpt:

It is generally agreed that water fluoridation is safe for persons with normal kidneys. Systemic fluorosis in patients with diminished renal function, however, seems a reasonable possibility. In such patients, fluoride may be retained with resulting higher tissue fluoride levels than in persons with normal renal function.

  • Skeletal fluorosis in humans: a review of recent progress in the understanding of the disease

    Endemic skeletal fluorosis is a chronic metabolic bone and joint disease caused by ingesting large amounts of fluoride either through water or rarely from foods of endemic areas. Fluoride is a cumulative toxin which can alter accretion and resorption of bone tissue. It also affects the homeostasis of bone mineral

    Acquired osteosclerosis is a rare disorder of bone formation but an important consideration in adults with sclerotic bones or elevated bone density results.

With empty professional anamnesis as cause was found the presence of a chronic renal insufficiency with simultaneously increased fluor content of drinking 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

    1. A case of osteosclerosis, exhibiting in addition mottled enamel, severe anemia showing no response to anti-anemic therapy, and bilateral renal lesions is reported. 2. The diagnosis of fluoride osteosclerosis was proved by the history of a long residence in areas of endemic fluorosis and by fluorine analysis of the patient's

  • 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.

  • 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

  • Skeletal Fluorosis & Individual Variability

    One of the common fallacies in the research on skeletal fluorosis is the notion that there is a uniform level of fluoride that is safe for everyone in the population. These "safety thresholds" have been expressed in terms of (a) bone fluoride content, (b) daily dose, (c) water fluoride level, (d) urinary fluoride level, and (e) blood fluoride level. The central fallacy with each of these alleged safety thresholds, however, is that they ignore the wide range of individual susceptibility in how people respond to toxic substances, including fluoride.

  • "Pre-Skeletal" Fluorosis

    As demonstrated by the studies below, skeletal fluorosis may produce adverse symptoms, including arthritic pains, clinical osteoarthritis, gastrointestinal disturbances, and bone fragility, before the classic bone change of fluorosis (i.e., osteosclerosis in the spine and pelvis) is detectable by x-ray. Relying on x-rays, therefore, to diagnosis skeletal fluorosis will invariably fail to protect those individuals who are suffering from the pre-skeletal phase of the disease. Moreover, some individuals with clinical skeletal fluorosis will not develop an increase in bone density, let alone osteosclerosis, of the spine. Thus, relying on unusual increases in spinal bone density will under-detect the rate of skeletal fluoride poisoning in a population.
