-
- Erythromelalgia is a syndrome of sudden intensive spastic dilation of
- blood vessels (paroxysmal vasodilation). This causes burning pain, increased
- skin temperature, and redness of the feet and, less often, the hands.
-
- Symptoms
-
- Erythromelalgia is characterized by attacks of burning pain in hot red feet
- or hands. Increase of symptoms is often triggered by hot weather. Symptoms
- may remain mild for years or they may become so severe that total disability
- can result.
-
- Causes
-
- Primary Erythromelalgia may be transmitted as a dominant hereditary disorder.
- (Human traits including the classic genetic diseases, are the product of the
- interaction of two genes for that condition, one received from the father and
- one from the mother. In dominant disorders, a single copy of the disease
- gene (received from either the mother or father) will be expressed
- "dominating" the normal gene and resulting in appearance of the disease. The
- risk of transmitting the disorder from affected parent to offspring is 50%
- for each pregnancy regardless of the sex of the resulting child.)
-
- Secondary Erythromelalgia may occur in patients with proliferative
- disorders of the bone marrow, hypertension, impairment of the return of
- venous blood from the legs (venous insufficiency), diabetus mellitus, or
- polycythemia vera.
-
- Affected Population
-
- Males and females are affected in equal numbers.
-
- Related Disorders
-
- Causalgia syndrome or Traumatic Erythromelalgia is characterized by a
- persistent diffuse burning pain, especially in the palms of the hands and the
- soles of the feet. It is aggravated by minimal physical stimuli such as
- friction and heat.
-
- Therapies: Standard
-
- Attacks of Erythromelalgia can sometimes be avoided or reduced by rest,
- elevation of the extremity, and cold applications to the affected area.
- Correction of the underlying disease in secondary forms of Erythromelalgia is
- indicated. In Primary Erythromelalgia modest doses of aspirin may produce
- relief, but this therapy is not always successful.
-
- Avoiding factors that produce vasodilation is usually helpful. The use
- of ephedrine, propranolol or methysergide may also produce relief in some
- patients.
-
- Therapies: Investigational
-
- Sodium nitroprusside (sodium ferri cyanide) has been used intravenously with
- some success on Erythromelalgia. It is a potent antihypertensive drug that
- can cause serious side effects. More research is necessary to determine the
- safety and effectiveness of this drug for Erythromelalgia.
