Abstract
This article addresses the Human T-lymphotropic virus (HTLV). This subject comprises the Clinical Protocol and Therapeutic Guidelines for Comprehensive Care for People with Sexually Transmitted Infections, published by the Brazilian Ministry of Health. HTLV-1/2 infection is a public health problem globally, and Brazil has the largest number of individuals living with the virus. HTLV-1 causes several clinical manifestations of neoplasm (adult T-cell leukemia/lymphoma) and inflammatory nature, such as HTLV-1-associated myelopathy and other manifestations such as uveitis, arthritis, and infective dermatitis. These pathologies have high morbidity and mortality and negatively impact the quality of life of infected individuals. This review includes relevant information for health authorities professionals regarding viral transmission, diagnosis, treatment, and monitoring of individuals living with HTLV-1 and 2 in Brazil. HTLV-1/2 transmission can occur through blood transfusion and derivatives, injectable drug use, organ transplantation, unprotected sexual intercourse, and vertical transmission.

Abstract
This manuscript is related to the chapter about human T-cell lymphotropic virus (HTLV) that is part of the Clinical Protocol and Therapeutic Guidelines for Comprehensive Care for People with Sexually Transmitted Infections, published by the Brazilian Health Ministry. HTLV-1/2 infection is a worldwide public health problem and Brazil has the largest number of individuals living with the virus. HTLV-1 causes a variety of clinical manifestations of a neoplastic nature, such as adult leukemia/T-cell lymphoma, and also of an inflammatory nature, such as HTLV-1-associated myelopathy, as well as other manifestations such as uveitis, arthritis and infective dermatitis. These pathologies have high morbidity and mortality and negatively impact the quality of life of infected individuals. This review includes relevant information for health service managers and workers regarding virus transmission modes, diagnosis, treatment and monitoring of individuals living with HTLV-1 and 2 in Brazil.

Lymphotropic Viruses EBV, KSHV and HTLV in Latin America: Epidemiology and Associated Malignancies. A Literature-Based Study by the RIAL-CYTED. Cancers (Basel) 2020; 12:E2166. [PMID: 32759793 PMCID: PMC7464376 DOI: 10.3390/cancers12082166] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2020] [Revised: 07/11/2020] [Accepted: 07/15/2020] [Indexed: 02/06/2023] Open
Abstract
The Epstein-Barr virus (EBV), Kaposi sarcoma herpesvirus (KSHV) and human T-lymphotropic virus (HTLV-1) are lymphomagenic viruses with region-specific induced morbidity. The RIAL-CYTED aims to increase the knowledge of lymphoma in Latin America (LA), and, as such, we systematically analyzed the literature to better understand our risk for virus-induced lymphoma. We observed that high endemicity regions for certain lymphomas, e.g., Mexico and Peru, have a high incidence of EBV-positive lymphomas of T/NK cell origin. Peru also carries the highest frequency of EBV-positive classical Hodgkin lymphoma (HL) and EBV-positive diffuse large B cell lymphoma, not otherwise specified (NOS), than any other LA country. Adult T cell lymphoma is endemic to the North of Brazil and Chile. While only few cases of KSHV-positive lymphomas were found, in spite of the close correlation of Kaposi sarcoma and the prevalence of pathogenic types of KSHV. Both EBV-associated HL and Burkitt lymphoma mainly affect young children, unlike in developed countries, in which adolescents and young adults are the most affected, correlating with an early EBV seroconversion for LA population despite of lack of infectious mononucleosis symptoms. High endemicity of KSHV and HTLV infection was observed among Amerindian populations, with differences between Amazonian and Andean populations.

Clinicopathological aspects and proviral load of adulthood infective dermatitis associated with HTLV-1: Comparison between juvenile and adulthood forms. PLoS Negl Trop Dis 2020; 14:e0008241. [PMID: 32330142 PMCID: PMC7202657 DOI: 10.1371/journal.pntd.0008241] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2019] [Revised: 05/06/2020] [Accepted: 03/22/2020] [Indexed: 11/28/2022] Open
Abstract
Background Infective dermatitis associated with human T-cell lymphotropic virus type-1 (HTLV-1), (IDH), is a chronic eczema occurring in HTLV-1 infected children. Rare cases of adulthood IDH have been reported and no study until now aimed to compare juvenile and adulthood IDH. Methodology/Principal findings Twelve cases of adulthood IDH followed for a mean time of 7.5 years were analyzed according to clinicopathological and molecular aspects, comparing them to juvenile IDH cases. Diagnosis was based on the modified major criteria used for juvenile IDH. Proviral load (PVL) assessment was performed by real-time PCR technique. Adulthood IDH presented similar clinicopathological and molecular aspects compared to juvenile IDH. The morphology of lesions and areas of involvement were similar, except for the involvement of the ankles and inframammary folds in the adulthood form. HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP) occurred in six adulthood IDH patients, with almost equal frequency. However, at least in two patients, HAM/TSP appeared prior to IDH, differently from what was observed in juvenile IDH. Conclusions/Significance Adulthood IDH is similar to juvenile IDH according to clinicopathological aspects and PVL levels. Therefore, the same modified major diagnostic criteria for juvenile IDH can be applied to both forms. HTLV-1 infection is most prevalent in developing countries, and in Brazil, it is most prevalent in poor black communities. The majority of infected people are asymptomatic, but a minority can develop adult T-cell leukemia/lymphoma, HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP) and/or infective dermatitis associated with HTLV-1 (IDH), the subject of this study. IDH is an exudative chronic eczema that always involves the scalp and retroauricular regions and is characterized by its prompt response to antimicrobial therapy. First described in Jamaican children in the sixties, only in 2001 adulthood onset of IDH was reported, and since then little literature has been produced concerning it. Thus, we aimed to provide a thorough description of this relatively new subtype of IDH, investigating its clinical, pathological and molecular aspects, comparing them to juvenile IDH. Apart from minor differences, such as involvement of extra body sites and earlier onset of HAM/TSP, adulthood IDH is very similar to its juvenile counterpart, and the same diagnostic criteria can be applied to both.

Abstract
Adult T-cell leukemia/lymphoma (ATLL) is an aggressive peripheral T-cell lymphoma caused by the human T-lymphotropic virus type-1 (HTLV-1). The skin is affected in approximately half of ATLL patients, and it may be the first manifestation of the disease. The skin lesions of ATLL are polymorphous, and depending on the type of skin eruption, it is possible to predict the prognosis of the disease. Besides specific skin lesions, other non-specific lesions and increased risk of cutaneous and systemic infections are observed. In this article, we describe the different skin lesions of ATLL patients (specific, non-specific, and infectious lesions), the different histopathological patterns, and the association of clinicopathological characteristics with prognosis. Recognition of ATLL skin lesions is essential for the correct management and the search for the virus, even in non-endemic regions, where global migration may bring HTLV-1 infected individuals.

Abstract
Infective dermatitis associated with HTLV-1 (IDH) is the main cutaneous marker of
HTLV-1 infection. This disease occurs primarily in children and should be
differentiated from other eczemas, especially from atopic dermatitis. The
largest series of IDH are from Jamaica and Brazil. There are an estimated 15 to
20 million infected people in the world, and Brazil is one of the endemic
regions. Studies suggest that IDH in children may be a marker for the
development of T-cell leukemia/lymphoma (ATL) or myelopathy associated with
HTLV-1/tropical spastic paraparesis (HAM / TSP) in adulthood.

Abstract
Tropical skin diseases are infectious conditions influenced by factors such as nutrition, housing, and the environment. Migration patterns have caused these conditions to be seen all around the world, not only in developing countries. Many of these diseases have a different presentation in childhood, which changes the diagnostic approach and management options. In this article, we review some of the most common tropical mycobacterial, protozoan, parasitic, and viral dermatologic conditions in children, including their epidemiologic, clinical, diagnostic, and therapeutic aspects.

Expansion of natural killer cells in peripheral blood in a Japanese elderly with human T-cell lymphotropic virus type 1-related skin lesions. Case Rep Dermatol Med 2014; 2014:937513. [PMID: 25431695 PMCID: PMC4241692 DOI: 10.1155/2014/937513] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2014] [Revised: 10/16/2014] [Accepted: 10/20/2014] [Indexed: 12/04/2022] Open
Abstract
Natural killer (NK) cells were proposed to play an important role in the pathogenesis of human T-cell lymphotropic virus type 1- (HTLV-1-) associated neurologic disease. Our patient was a 77-year-old Japanese man, who had been treated for infective dermatitis associated with HTLV-1 for nearly 10 years. When referred to us, he had facial eczema/edema as well as extensive dermatitis at the neck/upper chest and nuchal area/upper back regions. Dermal lesions had CD3+CD4+ cells, but no NK cells. Flow cytometry of his peripheral blood showed a phenotype of CD2+ (97%), CD3+ (17%), CD4+ (12%), CD7+ (94%), CD8+ (6%), CD11c+ (70%), CD16+ (82%), CD19+ (0%), CD20+ (0%), CD56+ (67%), HLA-DR+ (68%), and NKp46+ (36%). Absolute numbers of CD56+NK cells in the peripheral blood were in a range of 986/μL–1,270/μL. The expanded NK cells in the peripheral blood are considered to be reactive, to maintain the confinement of the HTLV-1-positive CD4+ cells in the skin, and to prevent the progression of the disease.
