Summary
Background. Antiretroviral therapy (ART) may be responsible for hypersensitivity reactions varying in severity, clinical manifestations and frequency. Case report. We report the case of a 47-year-old woman with HIV infection who developed a delayed mucocutaneous reaction after treatment with ART. Hypersensitivty reaction (HR) to emtricitabine and tenofovir was considered probable based on positive patch tests (PT) and hypersensitivity reaction to nevirapine was con-firmed by drug provocation test. Discussion. The diagnosis of HR to ART remains a diagnostic challenge, partly due to unknown mechanism and the absence of validated diagnostic tools. Patch testing may represent a useful method for confirming hypersensitivity. Further investigation in this area is required, so that successful management strategies can be offered, preventing loss of potent and viable antiretroviral agents.
