Years later, she developed neurological symptoms, with progressive gait deterioration and sphincter incontinence. All of this led to the diagnosis of HTLV-1 infection. There are several aspects of the paper that miss important information. Firstly, the earliest case of HTLV-1 infection in Spain was reported in 1989 in Barcelona in a Spanish nun with TSP symptoms who had lived in Latin America, where she had been transfused.<a class="elsevierStyleCrossRef" href="#bib0010"><span class="elsevierStyleSup">2</span></a> As of December 2019, the Spanish HTLV study group has registered a total of 389 cases. More than 65% have been observed in people from Latin America, but it should be noted that 17% are native Spaniards. The total number of TSP cases reported in Spain is 45.<a class="elsevierStyleCrossRef" href="#bib0015"><span class="elsevierStyleSup">3</span></a> Secondly, HTLV-1 is a sexually transmitted virus, with male-to-female transmission being more efficient than vice versa. The authors point out that both the woman and her husband denied having had extramarital relations, but do not mention whether the presence of HTLV-1 antibodies in the husband was ruled out. In our setting, most people with HTLV-1 infection have acquired the infection sexually.<a class="elsevierStyleCrossRef" href="#bib0015"><span class="elsevierStyleSup">3</span></a> On the contrary, we have no evidence of HTLV-1 transmission through blood transfusions carried out in Spain, with the exception of the case reported here. Leukoreduction of blood components was introduced in Spain in 2002 and this process drastically reduced the risk of transmission by blood transfusion. A different situation is transmission through solid organ transplantation from HTLV-1 positive donors. In our country, 5 cases of transmission have been reported from 2 organ donors from native Spaniards.<a class="elsevierStyleCrossRef" href="#bib0020"><span class="elsevierStyleSup">4</span></a> HTLV-1 infection is uncommon in our country, although the high number of residents from endemic areas, Latin America, and sub-Saharan Africa, leads us to suspect that we have a high rate of under-diagnosis. Regular epidemiological studies in at-risk populations and suspicion of infection in patients with compatible symptomatology can help us to identify a larger number of cases and implement effective preventive measures.</p></span>" "pdfFichero" => "main.pdf" "tienePdf" => true "NotaPie" => array:1 [ 0 => array:2 [ "etiqueta" => "☆" "nota" => "<p class="elsevierStyleNotepara" id="npar0005">Please cite this article as: de Mendoza C, Aguilera A, Eiros JM, Soriano V.
