Clinical characteristics of patients with human immunodeficiency virus and immune-mediated photodermatoses: A retrospective study of 39 patients.

Abstract

HIV/AIDS patients are susceptible to various infectious and inflammatory dermatoses. No systemic work has been done on HIV/AIDS patients with immune-mediated photodermatoses in China. Here, we aim to determine the clinical features of immune-mediated photodermatoses in HIV/AIDS patients. A retrospective analysis of HIV/AIDS patients with immune-mediated photodermatoses was carried out with demographic data, clinical characteristics, laboratory data, and follow-up data at the First Affiliated Hospital of Kunming Medical University between 2012 and 2019. The data were subjected to statistical analysis. A total of 39 HIV/AIDS patients with immune-mediated photodermatoses were enrolled, including 22 cases of polymorphic light eruption (PLE), 16 cases of chronic actinic dermatitis (CAD), and one actinic reticuloid. The CD4 count at the visit of the HIV-positive CAD group was lower than the PLE group (p=.049). The HIV-positive CAD group was more sensitive toward UVB than the PLE group (p=.020) and had a lower MED-UVB value (p=.044). There was no significant difference in UV tests among different categories of skin types. Immune-mediated photodermatoses are a manifestation of the advanced symptom of HIV infection, and sometimes also the presenting feature of HIV infection. Compared with HIV-positive PLE patients, CAD patients showed higher sensitivity to UVB radiation and had a lower MED-UVB value. The primary treatment for immune-mediated photodermatoses in HIV/AIDS patients is HAART and sun avoidance.
