Background: The management of HIV-positive patients with psoriasis is controversial and limited to individual cases or short series of patients. Objectives: To evaluate the safety and effectiveness of conventional and biologic immunosuppressive drugs in the treatment of patients with psoriasis and concomitant HIV infection. Methods: A retrospective multicenter study was conducted. The study included data from 2008 to 2016. Inclusion criteria were: HIV adult patients with moderate-to-severe psoriasis, HIV viral load determinations at baseline and at least after 6 months of treatment, and systemic immunosuppressive treatment for at least 6 months. A descriptive analysis was performed. Results: Twenty-three patients with plaque-type psoriasis and HIV infection (five with AIDS) were included. Median follow-up time was 3.2 years. The main drugs used were etanercept, methotrexate, and ustekinumab. In most cases, viral load and CD4 cell count not only remained stable but also improved throughout the follow-up. Six patients presented severe adverse events during the follow-up, four of them in the AIDS stage. At the end of the follow-up period, 76.5% of the patients had achieved a PASI 75. Conclusion: Biologic drugs, both anti-TNF alpha agents and ustekinumab, seem to have an acceptable safety profile and high effectiveness in HIV-positive patients.
