• W4247148191 abstract "This study reflects our experience in the management of posttransplant Kaposi Sarcoma (KS) and assesses the clinical relevance of monitoring HHV-8 DNA viral load in peripheral blood by qPCR. Retrospective study of all patients diagnosed with posttransplant KS during the period 1995–2019. In 8 patients, we performed a qPCR in serum for HHV-8 DNA detection at diagnosis and/or during follow-up. Data from 13 organ transplant recipients with a diagnosis of iatrogenic KS were collected. Reduction and/or discontinuation of one or more immunosuppressive agent(s) along with switching to an mTOR inhibitor was part of the treatment approach in 12 (92%) patients. Overall response rate (including complete response, partial response, and stable disease) was observed in 9 patients. At diagnosis, HHV-8 qPCR in serum was positive in 2 out of 5 patients. During follow-up, both positive cases turned negative, as a clinical response. Our work highlights the critical role of reduction of immunosuppression and conversion to an mTOR inhibitor in the management of posttransplant KS. Este estudio aporta nuestra experiencia en el manejo del sarcoma de Kaposi (SK) en pacientes trasplantados, y evalúa la relevancia clínica de la monitorización por qPCR de la carga viral del VHH-8 en sangre periférica. Estudio retrospectivo de los pacientes diagnosticados de SK postrasplante en el periodo de 1995-2019. En 8 pacientes, realizamos qPCR en suero para la detección de ADN del VHH-8 en el momento del diagnóstico o durante el seguimiento. Se recogieron datos de 13 trasplantados de órgano sólido con diagnóstico de SK. La reducción o discontinuación de uno o más fármacos inmunosupresores junto con el cambio a un inhibidor de mTOR constituyó una parte del tratamiento en 12 (92%) pacientes. Se observó respuesta al tratamiento (incluyendo respuesta completa, parcial o estabilidad) en 9 pacientes. En el diagnóstico, la qPCR en suero de VHH-8 fue positiva en 2 de 5 pacientes. Durante el seguimiento, ambos casos positivos se negativizaron al responder los pacientes al tratamiento. Nuestro trabajo muestra el papel esencial de la reducción de la inmunosupresión y la conversión a un inhibidor de mTOR en la estrategia terapéutica de SK en pacientes trasplantados." @default.
