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.[12]
- 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.
