Synopsis

Pruritus is a common problem in patients with human immunodeficiency virus (HIV) or AIDS. The itch can result from primary HIV-associated rashes, such as pruritic papular eruption and eosinophilic folliculitis, or it can accompany underlying skin conditions such as seborrheic dermatitis, photodermatitis, psoriasis, and atopic dermatitis. Pruritus can also reflect undiagnosed systemic disease or be idiopathic in up to 50% of patients, resulting in severe, chronic, and difficult to control symptoms.

Severe pruritus can occur either in patients who are well-controlled on antiviral therapy or in HIV-infected patients who are not on therapy. Treatment of pruritus should be guided by the primary morphology of the rash or lack thereof. A multiprong approach to treatment may be helpful as underlying dermatoses can be implicated. Idiopathic pruritus should be a diagnosis of exclusion.

Idiopathic, treatment-resistant pruritus is hypothesized to be secondary to the dysregulation of the immune response, which includes hyperactivation of the humoral response in HIV-infected patients. Eosinophilia and/or high IgE levels are sometimes present.
