چکیده

BACKGROUND Human T-cell lymphotropic virus type 1 (HTLV-1) screening of blood and organ donors is not mandatory in Germany because of its low prevalence (about 7/100 000). An HTLV-1 transmission event caused by a multiple organ donor was investigated. Validity of diagnostic procedures and HTLV-1 disease association in immunosuppressed organ recipients were analyzed. METHODS Two screening immunoassays and an immunoblot (confirmatory assay) were used for detection of HLTV-1/2 antibodies. Proviral DNA was quantified in blood and biopsies of organ recipients by HTLV-1 real-time polymerase chain reaction (PCR). RESULTS Proviral HTLV-1-DNA was detected in all blood samples of 3 organ recipients (1-100 copies/10(2) cells), but seroconversion was delayed for up to 2 years in screening assays and >6 years in the confirmatory assay. In 2 of 3 organ recipients, a cutaneous T-cell lymphoma was diagnosed 2 and 3 years after infection, respectively. Proviral HTLV-1 DNA concentration was almost 100 copies/10(2) cells in cutaneous lymphoma biopsies whereas in biopsies of other tissues ≤3.0 copies/10(2) cells were found. The third organ recipient did not suffer from lymphoma, but detailed clinical data on this patient were not available to us. CONCLUSIONS Biopsy results support an etiological role for HTLV-1 in these cases of primary cutaneous T-cell lymphoma after solid organ transplant. HTLV-1-associated lymphoma can arise quickly in immunocompromised transplant recipients. The diagnosis of potentially HTLV-1-associated disease in organ recipients may require PCR because of delayed seroconversion.

Frequency of Human T-Cell Lymphotropic Virus (HTLV) Type 1 and 2 Infection in HIV Infected Patients

Background and Objectives: Human T-cell lymphotropic viruses (HTLV) type 1 and 2 are retroviruses that share the same routes of transmission as human immunodeficiency virus (HIV). As a consequence of epidemiologic similarities, HIV and HTLV-1/2 co-infection is frequent. Due to the limited data, this study assessed the seroprevalence of HTLV-1/2 infections in HIV infected patients in Tehran, Ira...
