    Introduction And ObjectivesThis 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.Patients And MethodsRetrospective 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.ResultsData 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.ConclusionsOur work highlights the critical role of reduction of immunosuppression and conversion to an mTOR inhibitor in the management of posttransplant KS.Copyright © 2021 Elsevier España, S.L.U.
