Interferon-gamma-induced protein 10 is a 10-kd protein produced by human keratinocytes following an exposure to interferon gamma. Keratinocytes within psoriatic plaques and within delayed-type hypersensitivity reactions have been shown to stain strongly with an affinity-purified rabbit antibody prepared against interferon-gamma-induced protein 10, suggesting a possible role for interferon gamma in the production of the lesions. A psoriasiform eruption has been seen in patients with acquired immunodeficiency syndrome (AIDS). Its severity appears to correlate with the degree of immunodeficiency in the early stages of AIDS. We stained 10 lesions of psoriasiform dermatitis of AIDS with the anti-interferon-gamma-induced protein 10 antibody using immunoperoxidase techniques. As controls, we studied 10 lesions of non-AIDS psoriasis, six lesions of seborrheic dermatitis with psoriasiform hyperplasia, one lesion of lichen simplex chronicus, and four biopsy specimens of normal skin from patients with AIDS. In addition, normal skin specimens taken from patients with AIDS and human immunodeficiency virus-negative patients at time of autopsy were examined. An identical, strong and diffuse staining pattern was seen in all cases of psoriasiform dermatitis of AIDS, non-AIDS psoriasis, seborrheic dermatitis, and lichen simplex chronicus. The specimens of normal skin showed only weak basal layer staining with anti-interferon-gamma-induced protein 10. Thus, the presence of interferon-gamma-induced protein 10 in keratinocytes was associated with psoriasiform hyperplasia and could be detected in both AIDS-associated and classic psoriasis.

Pruritus is a common manifestation of dermatologic diseases, including xerotic eczema, atopic dermatitis, and allergic contact dermatitis. Effective treatment of pruritus can prevent scratch-induced complications such as lichen simplex chronicus and impetigo. Patients, particularly elderly adults, with severe pruritus that does not respond to conservative therapy should be evaluated for an underlying systemic disease. Causes of systemic pruritus include uremia, cholestasis, polycythemia vera, Hodgkin's lymphoma, hyperthyroidism, and human immunodeficiency virus (HIV) infection. Skin scraping, biopsy, or culture may be indicated if skin lesions are present. Diagnostic testing is directed by the clinical evaluation and may include a complete blood count and measurement of thyroid-stimulating hormone, serum bilirubin, alkaline phosphatase, serum creatinine, and blood urea nitrogen levels. Chest radiography and testing for HIV infection may be indicated in some patients. Management of nonspecific pruritus is directed mostly at preventing xerosis. Management of disease-specific pruritus has been established for certain systemic conditions, including uremia and cholestasis.
