Treatment
Medical Care
Removal of the inciting agent is the goal of treatment. Correcting fluid and electrolyte losses and rectifying any nutritional imbalances (vitamin-rich diets, vitamin-B complex) are of utmost importance in the treatment of the disease.
- Recently, the chelating agent meso 2,3-dimercaptosuccinic acid has been shown to be the preferred treatment modality. It can almost completely prevent methylmercury uptake by erythrocytes and hepatocytes.
- In the past, dimercaprol (British antilewisite; 2,3-dimer-capto-l-propanol) and D-penicillamine were the most popular treatment modalities. Disodium edetate (Versene) was also used.
- Neither disodium edetate nor British antilewisite has proven reliable. British antilewisite has now been shown to increase CNS levels and exacerbate toxicity.
- N -acetyl-penicillamine has been successfully given to patients with mercury-induced neuropathies and chronic toxicity, although it is not approved for such uses. It has a less favorable adverse effect profile than meso 2,3-dimercaptosuccinic acid.10
- Hemodialysis with and without the addition of L-cysteine as a chelating agent has been used in some patients experiencing acute renal failure from mercury toxicity.
- Peritoneal dialysis and plasma exchange also may be of benefit.
- Tolazoline (Priscoline) has been shown to offer symptomatic relief from sympathetic overactivity.
- Antibiotics are necessary when massive hyperhidrosis, which may rapidly lead to miliaria rubra, is present. This can easily progress to bacterial secondary infection with a tendency for ulcerating pyoderma.
Medication
The goals of pharmacotherapy are to remove the causing agent, to reduce morbidity, and to prevent complications.
Chelating agents
Succimer almost completely prevents methylmercury uptake by erythrocytes and hepatocytes.
Succimer (Chemet)
Metal chelating agent, analog of dimercaprol, used in lead poisoning. Available as 100-mg cap.
Adult
10 mg/kg q8h for 5 d, followed by 10 mg/kg q12h for 14 d
Pediatric
Administer as in adults
Do not administer concomitantly with edetate calcium disodium or penicillamine
Documented hypersensitivity
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
CBC with white blood cell differential and platelet count should be performed prior to and weekly during therapy; discontinue therapy if absolute neutrophil count drops to 1200/μ l and monitor until count returns to 1500/μ l or patients baseline neutrophil count; caution in renal or hepatic impairment; to prevent toxicity, patient should be well hydrated; adverse effects include rash, GI symptoms (eg, nausea, vomiting, diarrhea, appetite loss, metallic taste in mouth), and increases in serum transaminase levels
