Treatment of heavy metal toxicity, particularly for uranium, vanadium, and strontium, should be managed by specialists in toxicology or occupational medicine, and I recommend referring this patient to a medical toxicologist or poison control center for appropriate evaluation and treatment recommendations tailored to her specific situation. The patient's condition involves elevated levels of uranium, vanadium, and strontium, which requires careful consideration of the potential risks and benefits of chelation therapy. DMSA is primarily FDA-approved for lead poisoning, and its use for other heavy metals is often off-label 1. The appropriate dosing regimen would depend on several factors including the patient's kidney function, exact metal levels, symptoms, body weight, and overall health status. Before initiating chelation therapy, confirmation of metal toxicity through proper testing is essential, as is determining whether the patient is still being exposed to these metals. Treatment should include removing the source of exposure first. Additionally, chelation therapy carries risks including redistribution of metals to other tissues and depletion of essential minerals. The most recent and relevant study on chelation therapy for metal poisoning is from 2013, which highlights the importance of careful consideration of the role of chelation in the treatment of metal poisonings 1. Other studies have also discussed the use of chelating agents in the treatment of metal toxicity, including the use of DMSA, DMPS, and EDTA 2, 3. However, these studies do not provide specific guidance on the dosing of DMSA for the treatment of uranium, vanadium, and strontium toxicity. Therefore, it is essential to consult with a medical toxicologist or poison control center to determine the best course of treatment for this patient. It is also important to note that the patient's symptoms and laboratory results should be carefully evaluated to determine the extent of metal toxicity and the need for chelation therapy. In general, the treatment of heavy metal toxicity requires a comprehensive approach that includes removal of the source of exposure, supportive care, and careful consideration of the potential risks and benefits of chelation therapy. In this case, referral to a specialist in toxicology or occupational medicine is the most appropriate course of action.
