Overview
Brief Summary
The purpose of this research study is to show that non-steroidal treatment with intravenous immunoglobulin (IVIg) can replace current systemic immunosuppressive therapy in cutaneous lupus erythematosis (CLE) patients.
Detailed Description
The ultimate goal of this pilot project is to generate proof-of-concept data showing that treatment with intravenous immunoglobulin (IVIg) can replace current systemic immunosuppressive therapy in cutaneous lupus erythematosis (CLE) patients. This project has relevant clinical implications due to the severe side effects of and lack of response to current therapies. From the review of literature, it can be postulated that: 1. the beneficial effects of IVIg for patients with CLE should be prompt, with marked improvement within a few weeks; 2. clinical improvement should last several weeks after the last infusion; and 3. remission may be prolonged by maintenance IVIg therapy. Although this is only a non-controlled study, the investigator expects that IVIg will improve CLE, including those resistant to standard treatments. It is anticipated that treatment with IVIg will facilitate healing of extensive cutaneous lesions and achieve rapid remission. Maintenance therapy with repeated monthly pulses of IVIg is expected to keep the disease in remission during the treatment-free follow up observational period. The results will provide the basis a multicenter randomized controlled study to identify which CLE subsets will benefit the most and which protocol will provide the optimal clinical outcome.

Arms & Interventions
IVIg as a monotherapy
IVIg will be used as a first line treatment. Topical treatment will be stopped at the beginning of IVIg therapy.
Intervention: IVIg
Outcomes
Primary Outcomes
Cutaneous Lupus Erythematosus Disease Area and Severity Index - Total Activity Score (CLASI - TAS)
Time Frame: Initial, 1st Visit - 9th Visit
Disease activity will be measured using the CLASI activity score that describes the activity of the disease. This score ranges from 0-70, with higher scores indicating more severe skin disease. This clinical assessment tool enables standardized assessments of response to therapy. Results expressed relative to the mean initial value of all patients, taken as 100%. Each proceeding visit will be relative to the initial visit. A decrease in percentage represents improvement while an increase in percentage indicates worsening of CLE. Visits occur on a month-to-month basis.
Skindex 29
Time Frame: Initial, 1st Visit - 9th Visit
The subjects also evaluated their skin-specific quality of life with the Skindex-29 - the questionnaire consisting of 29 items used to calculate three subscales: symptoms (pain, itch, burning, sensitivity), emotions (depression, anxiety, embarrassment, anger) and functioning (sleep, relationships with others). All assessments were repeated at all study visits. Results expressed relative to the mean initial value of all patients, taken as 100%. Each proceeding visit will be relative to the initial visit. A decrease in percentage represents improvement while an increase in percentage indicates worsening of CLE. Visits occur on a month-to-month basis.
Secondary Outcomes
- Mean Percent Change in Physician's Subjective Assessment of Improvement (PSAI)(Initial, 1st Visit - 9th Visit)
- Mean Percent Change in Physician's Subjective Assessment of Severity (PSAS)(Initial, 1st Visit - 9th Visit)
- Cutaneous Lupus Erythematosus Disease Area and Severity Index - Total Damage Score (CLASI - TDS)(Initial, 1st Visit - 9th Visit)
