RESUMO
INTRODUCTION: While the growing knowledge on HIV among solid organ transplant recipients (SOT) is limited to either pretransplant infection or allograft transmission, there are only sparse reports describing HIV-infection after transplantation through sexual route, the primary mode of transmission in the general population. METHODS: From two different centers, we report nine new cases of HIV infection in SOT recipients attributed to sexual acquisition: eight cases of kidney-transplant recipients and one heart-transplant recipient. FINDINGS: There were nine cases of post-transplant HIV-infection detected among 14 526 transplants performed 1998 to 2015. In 6/9 cases, infection was contracted 5 years after SOT. All but one patient had stable allograft function under immunosuppressive therapy. The main trigger to diagnosis was late CMV disease and sexually transmitted diseases; five patients had CDC-stage 3 HIV infection. In 7/9 patients, virologic response and CD4 recovery were achieved within 3 months after starting antiretroviral therapy (ART). After an average of 3.6 years post diagnosis, 5/9 patients remained alive with well-controlled infection and functioning allograft. CONCLUSION: Sexual acquisition of HIV infection after SOT represents a difficult challenge, as it may occur in any kind of transplant and at any time. The course of infection resembles that of the general population, with life-threatening infectious complications, but good response to ART. Assessment of lifestyle and risk behavior is paramount, as indications may be not disclosed without direct questioning.
