| الوصف: | Introduction The objective of this study was to describe the main characteristics of migrants diagnosed with human T-lymphotropic virus (HTLV) infection within the +Redivi Spanish network. Methods Patients with a diagnosis of HTLV type 1 or 2 in +Redivi from October 2009 to December 2020 were included. Diagnosis was based on positive HTLV serology (enzyme-linked immunosorbent assay (ELISA)/chemiluminescent immunoassay (CLIA)) with line immunoassay (LIA)/Western blot with/without polymerase chain reaction (PCR). Results A total of 107/17 007 cases (0.6%) had a final diagnosis of HTLV infection: 83 (77.67%) HTLV-1 infections, 6 (5.6%) HTLV-2 infections and 18 (16.8%) non-specified. The majority (76, 71%) were female, median age was 42 years and median time from arrival to Spain until consultation was 10 years. The group included 100 (93.5%) immigrants and 7 (6.6%) visiting friends and relatives (VFR)-immigrants. Most patients were from South America (71, 66.4%), followed by Sub-Saharan Africa (15, 14%) and Central America-Caribbean (13, 12.1%). Around 90% of patients were asymptomatic at presentation and diagnosed as part of screening programs. Median duration of follow-up was 5 years (IQR 2–7). Regarding HTLV-associated conditions, 90 patients (84.2%) had none, 7 (6.5%) had tropical spastic paraparesis , 5 (4.7%) had other associated conditions (dermatitis, uveitis, pulmonary disease), 3 (2.8%) had other neurological symptoms and 2 (1.9%) had adult T-cell leukaemia/lymphoma. No patients with HTLV-2 had HTLV-associated conditions. Four patients (3.7%) died. Concomitant diagnoses were found in 41 (38.3%) patients, including strongyloidiasis in 15 (14%) and HIV co-infection in 4 (3.7%). In 70% of patients, screening of potential contacts was not performed/recorded. Conclusions HTLV infections (the majority due to HTLV-1) were mainly diagnosed in asymptomatic migrants from Latin America (generally long-settled immigrants and the majority female with the consequent implications for screening/prevention). A high rate of association with strongyloidiasis was found. In the majority, screening of potential contacts was not performed, representing a missed opportunity for decreasing the under diagnosis of this infection. |
