Primary Outcome Measures:
  • Quantitation of epidermal innervation

Estimated Enrollment: 40
Study Start Date: April 2002
Estimated Study Completion Date: March 2004
Detailed Description:
To address the issues of skin denervation and its clinical and pathological correlations in lupus, we will study a systemic lupus erythematosus (SLE) cohort by evaluating the extent of cutaneous innervation. Patients are recruited from the rheumatologic clinic, and various neuropsychiatric syndromes are diagnosed based on clinical judgement following detailed history taking and neurological examinations. Skin biopsy with PGP 9.5 immunohistochemistry will be performed following established procedures after informed consent is obtained, and punches of 3 mm in diameter will be taken from the lateral side of the distal leg, 10 cm above the lateral malleolus. Intraepidermal nerve fibre densities will be compared with results of immunological, pathological, psychophysical, and electrophysical studies to understand the pathogenesis of peripheral neuropathy in SLE.

Ages Eligible for Study:   18 Years to 80 Years   (Adult, Senior)
Sexes Eligible for Study:   All

Inclusion Criteria:

  • Diagnosis of systemic lupus erythematosus based on the consensus criteria

Exclusion Criteria:

  • Conditions known to be associated with peripheral neuropathy, such as diabetes, uremia, alcoholism, and the administration of potentially neurotoxic agents, such as alkylating agents, methotrexate, cyclosporine, and antibiotics.
