Newsletter by Dr. Cannell: Does vitamin D cause kidney stones?
- Kidney stones are just like influenza. Scientists have not seen the forest for the trees yet.
- In winter we get more influenza due to vitamin D deficiency.
- In summer we eject kidney stones due to elevated serum levels of vitamin D healing the kidney.
Dr. Heaney's Comments:
- Kidney stones are of many types and have many causes.
- The most common types in the US are calcium oxalate stones.
- The stone should be analyzed so as to determine the approach to treatment.
- Whatever the stone type, stone formers have a defect in kidney production of a solution stabilizer, normally secreted into the urine.
- This keeps the commonly supersaturated urine from forming precipitates (which then aggregate into stones).
- There are two basic approaches indicated in most cases.
- One is to drink large amounts of water each day to keep the urine diluted
- The second is to reduce the urine content of components that form precipitates. For example, if the stone is a urate stone, medicines will be prescribed that reduce the body's production of uric acid. Or if the stone is calcium oxalate, large quantities of calcium should be ingested to block absorption of oxalic acid from the intestinal contents, thereby reducing the amount of oxalate that will have to be excreted through the kidneys. While high calcium intake sounds counter-intuitive, there is a solid scientific base for the recommendation, and persuasive clinical trial data showing that it works. Placing patients on low calcium diets will actually double the risk of having a second stone.
- There are several other approaches that might be taken, but the foregoing hit the main points. It's important to remember that the basic defect (absence of a solution stabilizer) persists, so whatever strategy works will have to become permanent.
- Vitamin D, in doses producing desirable serum levels of 25(OH)D (40-60 ng/ml or 100-150 nmol/L), does not adversely affect any of the components of this system

Background and objectives Despite the important role of vitamin D in maintaining bone health, many clinicians are reluctant to treat vitamin D deficiency in kidney stone formers because of the theoretical risk of increasing urinary calcium excretion. This study examined the effect of vitamin D repletion on urinary calcium excretion among stone formers.
Design, setting, participants, & measurements Participants (n=29) were recruited from urology clinics affiliated with New York Presbyterian Hospital. Enrollment criteria included a history of nephrolithiasis, urinary calcium excretion between 150 and 400 mg/d, and a serum 25-hydroxyvitamin D level <30 ng/ml. Participants were given oral ergocalciferol (50,000 IU/wk) for 8 weeks. Serum and 24-hour urine tests were repeated after 8 weeks.
Results Levels of 25-hydroxyvitamin D increased significantly after vitamin D repletion (17±6 and 35±10 ng/ml, P<0.001), but mean 24-hour urinary calcium excretion did not change (257±54 and 255±88 mg/d at baseline and follow-up, respectively, P=0.91). However, 11 participants had an increase in urinary calcium excretion ?20 mg/d; these participants also had an increase in urine sodium excretion, likely reflecting dietary variability. No participant experienced adverse effects from vitamin D, including hypercalcemia.
Conclusions Among stone formers with vitamin D deficiency, a limited course of vitamin D repletion does not seem to increase mean urinary calcium excretion, although a subset of individuals may have an increase. These data suggest that vitamin D therapy, if indicated, should not be withheld solely on the basis of stone disease, but 24-hour urinary calcium excretion should be monitored after repletion.

Nutrients, vitamins, probiotics, and herbal products may be risk factors, or alternately, protect against the formation of urinary stones. The purpose of this review was to update knowledge of the role of nutraceuticals in renal stone formation. A systematic search of the relevant literature published in PubMed in the last ten years was conducted and a narrative review of the data from the included studies was done. Search screened 513 studies that were reduced to 34 after evaluation by title and abstract; other 38 studies were retrieved by references of the selected studies.
- Beverages high fluid intake confirmed protective effect;
- orange juice protective effect;
- apple or grapefruit juice not confirmed as risk factors;
- sugar-sweetened soda and punch increased risk of stone formation.
- Energy intake: very high energy intake increased risk factor for women (especially after menopause);
- dietary acid load increased risk at equal levels of energy intake.
- Macronutrients confirmed increased risk of high protein intake.
- Calcium and Oxalate: calcium intake protective effect; oxalate intake only modest increase of risk in men and older women.
- Metal cations zinc and iron intake no clear impact on the risk of stone formation,
- dietary copper increased risk;
- manganese intake reduced risk of stone formation.
- Fruits and Vegetables decreased risk.
- Vitamins B6 intake not associated to risk of stone formation;
- vitamin C intake increased risk in men;
- vitamin D or supplemental vitamin D intake not associated to increased risk in men and younger women,
- suggestion of a higher risk in older women;
- Probiotics Gut colonization with Oxalobacter formigenes associated to lower risk of stone formation,
- effect of oxalate-degraders probiotics on urinary oxalate equivocal.
- Herbal products efficacy of some herbal products demonstrated in some trials, more investigations needed to confirm their efficacy and safety.
