Alopecia areata is an autoimmune condition resulting in hair loss and complete baldness (alopecia totalis). Published evidence says that it is mediated by T-lymphocytes. Plaquenil is an anti-inflammatory drug approved by the FDA for malaria, lupus erythematosus, and rheumatoid arthritis. It has an effect on T-lymphocyte mediated inflammation, making it a logical choice for a treatment trail for alopecia areata.

Primary Outcomes: Percent hair regrowth in each quadrant of the scalp will be estimated and statistical analysis performed to determine if there was any significant regrowth compared to pre-treatment photographs.
Expected Total Enrollment:  16

Alopecia areata is a high prevalence autoimmune disease with significant consequences. Alopecia areata is a tissue restricted autoimmune disease directed at the hair follicle, resulting in hair loss. Patients frequently suffer severe psychiatric consequences. This is especially true of girls and young women who become bald. The incidence of alopecia areata in the USA (Minnesota is 20.2 per 100,000 person-years with a lifetime risk of approximately 1.7%. There is no significant gender difference. The disease is often chronic with a remitting, relapsing course. Although it responds to immunosuppression, generalized immunosuppression has significant morbidity and treatment is frequently frustrating and not successful. New treatment options are essential. With evidence that alopecia areata is a T-lymphocyte mediated autoimmune condition it has become a model system for the study of pathogenesis and treatment of T-cell mediated autoimmunity and as such is a model for a host of additional T-cell mediated autoimmune conditions.

Criteria

Inclusion Criteria:

Exclusion Criteria:

1. Coexisting significant systemic disease that would increase risk of hydroxychloroquine (e.g. renal disease, liver disease, alcoholism, anemia, blood dyscrasia, psoriasis, porphyria) 2. Systemic immunosuppressive therapy within 3 weeks (e.g. prednisone, cyclosporin, azathioprine) 3. Immunosuppressive conditions (e.g. HIV infection, cancer immunotherapy genetic immunodeficiency 4. Medications with potential interaction to hydroxychloroquine (e.g. liver toxins, bone marrow toxins) 5. Pregnancy, or breast feeding 6. Women of child bearing potential not able or willing to use two methods of contraception at least one of which is not a hypersensitivity to 4-aminoquinolone compounds (chloroquine and hydroxychloroquine) 9.
