Leprosy

Back to Causes

Leprosy, also known as Hansen’s disease, is rarely seen in the United States, but it is common in developing countries and is one of the leading causes of peripheral neuropathy worldwide. Leprosy is a chronic bacterial disease involving the skin and nerves. It is characterized by potentially disfiguring skin lesions, peripheral nerve damage, and progressive debilitation. Neurological damage caused by leprosy may result in sensory loss, particularly in the hands and feet. Leprosy is difficult to transmit from person-to-person and has a long incubation period, which makes it difficult to determine where or when the disease in a particular individual was contracted. Children are more susceptible than adults to contracting the disease.

  • Muscle weakness
  • Numbness, pain or tingling in feet or hands
  • Skin lesions

Tests

(Not all evaluation and tests may be necessary)

  • Neurological exam
  • Electromyography
  • Nerve conduction velocity test
  • Skin or nerve biopsy
  • Blood tests

Treatments

(Not all treatments and therapies may be indicated)

Treatment focuses on relieving pain by reducing inflammation, slowing joint and bone damage and improving the ability to function with the disease.

  • Antibiotics
  • Corticosteroids 
  • Multidrug therapy:
    • Diaphenylsulfone (Dapsone®),
    • Rifampicin (Rifadin®)
    • Clofazimine (Lamprene®)
