Antiretroviral-Related Alopecia in HIV-Infected Patients

Abstract

Objective: To review the literature evaluating antiretroviral-related alopecia and to provide guidance on the differential diagnosis and management of this condition. Data Sources: A literature search was performed using PubMed, MEDLINE, Embase, International Pharmaceutical Abstracts (IPA), Cumulative Index to Nursing and Allied Health (CINAHL), and the Cochrane database (through May 2014). Relevant conference abstracts and product monographs were reviewed. Search terms included antiretroviral, individual antiretroviral classes and names, highly active antiretroviral therapy, HIV, AIDS, alopecia, hair, hair loss and drug. Study Selection and Data Extraction: English-language studies and case reports were included. A total of 16 articles and 1 conference abstract were retrieved, with a total of 46 patients with hair loss. Data Synthesis: The protease inhibitor class, in particular indinavir, was most commonly reported to cause hair loss, followed by the NRTI, lamivudine. The majority of cases presented with alopecia of the scalp alone, with a median time of onset of 2.5 months. Management involved discontinuing the drug in most cases, with at least partial reversal in half the cases. Conclusions: In antiretroviral-induced alopecia, discontinuation of the suspected agent is the optimal management, and hair regrowth should occur within 1 to 3 months. Management may also include replacing the offending medication with an antiretroviral less likely to cause hair loss. It is essential to rule out other causes of alopecia with a complete patient history, including characterization of the hair loss and assessment of the patient’s medical history, medication use, and family history of alopecia.
