Psoriasis in African-Americans: A caregivers' survey

Abstract

Background: Psoriasis is a common skin disease in Caucasians but less common in African-Americans. Aims: Our aim is to evaluate caregiver opinions regarding the clinical presentations and treatment of psoriasis in African-Americans compared to Caucasians. Patients/Methods: A survey was sent to 29 dermatologists who are opinion leaders in the field of psoriasis. The survey included a number of questions regarding the characteristics of the patients seen in their practice. Results: A total of 29 surveys were completed and returned. All of the dermatologists use the extent of disease as a criterion to determine the severity of the disease. Other criteria include scale, thickness, erythema, associated general symptoms, and dyspigmentation. About 66% of the respondents reported the different manifestations of disease, such as more dyspigmentation, thicker plaques, and less erythema in African-Americans. The most common first-line treatments for mild to moderate disease were high- potency topical steroids (68%) followed by topical vitamin D analogues (41%). For moderate to severe disease, the most commonly used first-line treatments were high-potency topical steroids (54%) and phototherapy (46%). Conclusions: The clinical manifestations of psoriasis in African-Americans are not exactly the same as in Caucasians. Physicians should be aware of the difference in clinical manifestations in African-Americans. Further research and large-scale studies are necessary to elucidate the differences in the clinical presentation, natural course of the disease, and the criteria used for the evaluation of severity among ethnic groups. © 2012-Journal of Drugs in Dermatology.
