Abstract
Hereditary polymorphic light eruption (HPLE) occurs in Indians of North and South America. Affected persons are sensitive to long ultraviolet radiation and therefore receive no substantial benefit from conventional sunscreens. We have treated 46 patients with HPLE at the Red Lake Reservation, Minn, with topically administered dihydroxyacetone and lawsone, orally given beta carotene, or both. Oral beta carotene afforded adequate photoprotection to 33 patients, and four additional patients were protected with the combined use of oral and topical agents. Epidemiologic studies support our proposals that HPLE is a causative factor in streptococcal pyoderma in the American Indian and may be associated with epidemics of streptococcal glomerulonephritis.
