Treatment
Medical Care
Treatment of aluminum toxicity includes elimination of aluminum from the diet, TPN, dialysate, medications, antiperspirants, and an attempt at the elimination and chelation of the element from the body's stores.- Avoidance of aluminum is easily achieved once the need to do so is recognized.
- Elimination is accomplished through the administration of deferoxamine through any of several routes.
- Deferoxamine, the metal-free ligand of the iron-chelate isolated from the bacterium Streptomyces pilosus, is used for acute and chronic iron toxicity and aluminum toxicity.
- It has a high affinity for ferric iron and does not affect iron in hemoglobin or cytochromes.
Surgical Care
No surgical care is applicable to this disorder. Hemodialysis is performed in conjunction with deferoxamine as therapy for whole body chelation
Consultations
- Usually, a nephrologist is already a part of the patient's medical team. If not, one should be consulted early in the course.
- A hematologist and a neurologist may be able to assist with the patient's care.
Diet
Since dietary aluminum is ubiquitous, there are no specific dietary guidelines for its avoidance. Special diets should be maintained for specific associated disease entities (eg, diabetes, renal failure).
Activity
Activity modification may not be necessary unless the patient is at risk for frequent falls. If this is the case, a home attendant or family member should assist the patient with daily living activities.
Medication
The goals of pharmacotherapy are to reduce morbidity and to prevent complications.
Metal chelators
Bind free metal and do not chelate other trace metals of nutritional importance. Metals are excreted in the urine and bile.
Deferoxamine mesylate (Desferal mesylate)
Metal-free ligand of the iron chelate isolated from the bacterium S pilosus. Used for acute and chronic iron toxicity as well as aluminum toxicity and has a high affinity for ferric iron. Does not affect iron in cytochromes or hemoglobin. PO/IM administration not established. Several case reports and cohorts using varying doses indicate effectiveness when administered IV.
Adult
6 g/wk average at 14.5 mg/kg/h IV 3 times/wk during first 2 h of dialysis or 85 mg/kg/wk at 14.5 mg/kg/h IV
CAPD: 500-750 mg added to each 2-L bag of dialysate for approximately 2 mo; varying amount of exchanges using deferoxamine (eg, only hs, once/d) would prolong therapy; alternatively, administer prolonged SC infusion over 8-16 h via pump
Pediatric
Not established; consult nephrologist
Vitamin C >500 mg/d can cause cardiac dysfunction; concomitant administration with prochlorperazine can cause transient loss of consciousness; gallium-67 scanning results can be affected
Documented hypersensitivity, profound hypotension, anuria, and severe renal disease without ability to dialyze
Pregnancy
C - Fetal risk revealed in studies in animals but not established or not studied in humans; may use if benefits outweigh risk to fetus
Precautions
Tachycardia, hypotension, and shock may occur in patients receiving long-term therapy and could add to the cardiovascular collapse due to iron toxicity; adverse GI effects of the drug include abdominal discomfort, nausea, vomiting, and diarrhea, which may add to the symptoms of acute iron toxicity; flushing and fever are reported
