Characterization of plantar verrucae among individuals with human immunodeficiency virus.

ABSTRACT

Plantar verrucae, caused by human papillomavirus (HPV), are commonly found in patients who have tested positive for the antibodies to human immunodeficiency virus (HIV). A better understanding of the characteristics of plantar verrucae in HIV+ patients in needed. A pilot study was conducted concentrating on three characteristics--the size, the number, and the clinical type--of verrucae present in this population. These parameters were studied in HIV+ and HIV- populations, and they were evaluated in relation to the CD4 levels of HIV+ individuals. The HIV+ individuals presented with plantar verrucae that were larger and more numerous than those found in HIV- individuals. The HIV+ population presented with all three clinical types of plantar verrucae and had significantly more mosaic-type warts than did HIV- individuals. The three characteristics did not correlate with CD4 cell counts, suggesting that the severity and extent of HPV infection do not depend on the level of immunosuppression of the HIV+ patient.
