The incidence of anomalies associated with vitiligo has been variously reported. Diabetes mellitus, pernicious anemia, hyperthyroidism, hypothyroidism, and Addison's disease have all been linked with vitiligo. The association of antithyroglobulin antibodies and antiparietal cell antibodies with vitiligo have added support to the theory of an autoimmune cause, as has the recent association of HLA 13 with vitiligo and antithyroid antibodies. However, we were unaware of any study dealing exclusively with vitiligo in black patients. For this reason, we studied the black patients attending the vitiligo clinic at Cook County Hospital, Chicago, for any evidence of the previously mentioned conditions, including determination of antithyroglobulin and antiparietal cell antibodies. No patient was admitted to the study prior to being examined independently by three investigators. If there was any disagreement on the diagnosis, the patient was excluded from the study.
Patients and Methods
Fifty black patients were randomly selected from the vitiligo clinic
