Abstract
Human T-cell lymphotropic virus type 1 (HTLV-1) is endemic in some regions and its vertical transmission occurs mainly through breastfeeding. About 10% of carriers develop associated diseases including HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP), adult T-cell leukemia/lymphoma (ATL) and infectious dermatitis associated with HTLV-1 (IDH). We searched for available case reports of early-onset HAM/TSP and ATL to evaluate demographic and disease aspects in infantile-juvenile patients. In the reviewed literature, 27 HAM/TSP and 31 ATL cases were found. In almost all of them, the most likely route of transmission was through breastfeeding. ATL is rarely reported, notwithstanding it may be underestimated because T-cell lymphomas are not investigated for HTLV-1 infection in this age group. IDH was frequently associated with HAM/TSP. The investigation of HTLV-1 infection in pregnant women is an important matter of public health and should be mandatory in endemic countries.

Abstract
Adult T-cell leukemia/lymphoma (ATL) is caused by the human T-cell lymphotropic virus type 1 (HTLV-1) which is endemic in countries of Caribbean and Central and South America. We performed a systematic search and review to identify publications on ATL in these countries to verify if this disease was getting recognition in these regions as well as the characteristics of the observed cases. The median age of 49.4 years was lower than that referred to in Japan. According to our findings in most Brazilian states and in some other countries, ATL is not being recognized and should be strongly considered in the differential diagnosis of T-cell leukemias/lymphomas. Failure to identify these cases may be due to the unsystematic realization of serology for HTLV-1 and phenotypic identification of non-Hodgkin lymphomas that may result from lack of resources. Detection of ATL cases has been more feasible with cooperation from foreign research centers. A huge effort should be made to improve the surveillance system for ATL diagnosis in most of the South- and Central-American and Caribbean countries, and this attitude should be embraced by public organs to support health professionals in this important task.

Abstract
Human T-lymphotropic virus 1 (HTLV-1) is a retrovirus that produces a persistent infection. Two transmission routes (from mother to child and via sexual intercourse) favor familial clustering of HTLV-1. It is yet unknown why most HTLV-1 carriers remain asymptomatic while about 10% of them develop complications. HTLV-1 associated diseases were originally described as sporadic entities, but familial presentations have been reported. To explore what is known about family aggregation of HTLV-1-associated diseases we undertook a systematic review. We aimed at answering whether, when, and where family aggregation of HTLV-1-associated diseases was reported, which relatives were affected and which hypotheses were proposed to explain aggregation. We searched MEDLINE, abstract books of HTLV conferences and reference lists of selected papers. Search terms used referred to HTLV-1 infection, and HTLV-1-associated diseases, and family studies. HTLV-1-associated diseases considered are adult T-cell leukemia/lymphoma (ATLL), HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP), HTLV-1-associated uveitis, and infective dermatitis. Seventy-four records reported HTLV-1-associated diseases in more than one member of the same family and were included. Most reports came from HTLV-1-endemic countries, mainly Japan (n = 30) and Brazil (n = 10). These reports described a total of 270 families in which more than one relative had HTLV-1-associated diseases. In most families, different family members suffered from the same disease (n = 223). The diseases most frequently reported were ATLL (115 families) and HAM/TSP (102 families). Most families (n = 144) included two to four affected individuals. The proportion of ATLL patients with family history of ATLL ranged from 2 to 26%. The proportion of HAM/TSP patients with family history of HAM/TSP ranged from 1 to 48%. The predominant cluster types for ATLL were clusters of siblings and parent-child pairs and for HAM/TSP, an affected parent with one or more affected children. The evidence in the literature, although weak, does suggest that HTLV-1-associated diseases sometimes cluster in families. Whether familial transmission of HTLV-1 is the only determining factor, or whether other factors are also involved, needs further research.

Abstract
BACKGROUND Dermatologic manifestations are quite common in patients with adult T cell leukemia and lymphoma and patients with myelopathy and/or tropical spastic paraparesis associated with human T cell lymphotropic virus type 1 (HTLV-1). The aim of this study was to investigate dermatological findings presented by 30 members of a Brazilian family, half of whom are infected with HTLV-1 (as confirmed by enzyme-linked immunosorbent assay and Western blot). METHODS The subjects underwent dermatologic examination and laboratory assessment, which included the search for the HTLV-1 genome in peripheral blood mononuclear cells (PBMCs) by qualitative and semiquantitative polymerase chain reaction (PCR) and in skin samples by nested qualitative PCR and immunofluorescence assay. RESULTS We found that cases of xerotic dermatological alterations, including 3 cases of acquired ichthyosis, were more frequent among the infected patients (7 cases vs. none among the uninfected individuals; P=.0063). Other lesions observed in this group included impetigo, scabies, epidermal nevus, herpes zoster scar, rosacea, and juvenile acne. One HTLV-1-infected individual presented with concurrently acquired ichthyosis, impetigo, scabies, dermatophytosis, and seborrheic dermatitis. The PCR performed on PBMCs and skin samples from 24 patients confirmed the serological results in all cases. Additionally, the HTLV-1 proviral load was higher in patients with >1 skin lesion. Finally, HTLV-1 could be identified in the skin by immunofluorescence assay, which, by use of PCR as the gold standard, showed a sensitivity and specificity of 61.5% and 100%, respectively. CONCLUSIONS Altogether, these clinical and laboratory findings point to an HTLV-1 tropism toward the skin, even in HTLV-1 carriers without adult T cell leukemia/lymphoma or HTLV-1-associated myelopathy and/or tropical spastic paraparesis.

Abstract
We report here the rare case of a family predisposed to adult T-cell leukemia (ATL). Six of seven siblings developed ATL with ages of onset of 77, 48, 60, 64, 72, and 62 years old. Although virological tests for human T-lymphotropic virus type 1 were unavailable for two of the six patients, all were diagnosed with ATL based on their clinical, hematological, and histopathological features. Two of the six patients were tested for HLA haplotypes using fresh blood samples, and both were carriers of the HLA-A*26 allele known in the southern Japanese population to be susceptible to ATL. This series of genetic traits may help explain the familial predisposition to ATL.

Abstract
Human T-cell leukemia virus type 1 (HTLV-1) was the first human retrovirus to be identified in the early 1980s. The isolation and identification of a related virus, HTLV-2, and the distantly related human immunodeficiency virus (HIV) immediately followed. Of the three retroviruses, two are associated definitively with specific diseases, HIV, with acquired immune deficiency syndrome (AIDS) and HTLV-1, with adult T-cell leukemia/lymphoma (ATLL) and tropical spastic paraparesis/HTLV-1-associated myelopathy (TSP/HAM). While an estimated 10-20 million people worldwide are infected with HTLV-I, infection is endemic in the Caribbean, parts of Africa, southwestern Japan, and Italy. Approximately 4% of HTLV-I infected individuals develop ATLL, a disease with a poor prognosis. The clinical manifestations of infection and the current biology of HTLV viruses with emphasis on HTLV-1 are discussed in detail. The implications for improvements in diagnosis, treatment, intervention, and vaccination are included, as well as a discussion of the emergence of HTLV-1 and -2 as copathogens among HIV-1-infected individuals.

Abstract
T-cell leukemia/lymphoma (T-c LL) associated with prior infection with HTLV-I is rarely described in children. We present herein, the clinical, morphological, and virologic features of T-c LL, which occurred in eight pediatric cases with similar features of ATLL described in adults. There were three girls and five boys with age ranging from 2 to 18 years. Lymphoadenopathy, hepatosplenomegaly and marked skin lesions were presented in all cases. Five patients had hypercalcemia. The diagnostic criteria of T-c LL were based on both morphological and immunophenotypical analyses characterized by T-cell markers positively. Seven cases were cCD3+, CD4/CD25+, whereas CD1a and TdT were negative in all cases tested. HTLV-I antibodies were detected in all cases. HTLV-I provirus integration of at least one provirus was seen in all cases tested by molecular analysis. Mother-to-child transmission of HTLV-I was demonstrated in six cases. Interestingly, a homozygous deletion in p16 gene locus was observed in all four cases studied, while exons 7 and 8 of p53 were deleted in one child. The deletion of the p16(INK4A)/p14(ARF) or mutation of p53, key regulatory protein of cell cycle checkpoint in G1/S progression, found in five of the eight pediatric patients suggests that in these cases genetic lesions associated with HTLV-I infection may predispose for an early onset of leukemia.

Abstract
Here we describe two Caucasian brothers who developed adult T-cell leukemia/lymphoma (ATLL), within a short period of time. These two patients have never left Argentina. Their parents are dead and according to the family history it is possible that the mother may have been affected by spastic paraparesis. The daughters reported that their mother had suffered from increasing difficulty in walking for many years which finally made it impossible for to her walk. There are no other data to support the presumptive diagnosis. One of the patients presented with acute disease while the other had a lymphoma type disorder. Both were positive for HTLV 1. The first patient died with disease progression ten months after diagnosis and the second is in partial remission 13 months after diagnosis. Immunophenotyping showed CD4+, CD5+, CD3+, CD2+, CD8 (-). Two asymptomatic brothers with positive HTLV 1 serology were detected. This is the first family case that has been reported in Argentina.
