ABSTRACT

Summary The Human T-lymphotropic virus type 1 (HTLV-1), a retrovirus with oncogenic properties, affects around ten to twenty million people worldwide. The most common disorders associated with HTLV-1 infection are T-cell leukemia/lymphoma (ALT) and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). Studies have reported other clinical manifestations in HTLV-1 seropositive patients, including inflammatory disorders, co-infections with opportunistic agents, and pulmonary diseases. Objective: Here, we aim to describe a cohort of juvenile patients with confirmed HTLV-1 infection that showed clinical manifestations other than neurological symptoms. Methodology and patients: Retrospective analysis of clinical data describing background and clinical findings of 12 juvenile patients with confirmed HTLV-1 infection, attended during January 2018 to February 2020 in a pediatric referral hospital in Cali, Colombia. Results: 11 out 12 patients were from Colombia´s Pacific coast, 10 suffered from significant nutritional deficiencies. Six exhibited dermatological findings, 3 compatible with infective dermatitis. None of the cases exhibited clinical or laboratory findings suggesting ALT or HAM/TPS. Eight patients had structural lung disease assessed by chest Computed Tomography (CT) scans; 4 of them tested positive for galactomannan antigen in bronchoalveolar fluid suggesting pulmonary aspergillosis, and 2 others exhibited a positive PCR testing for tuberculosis. Three patients were diagnosed with autoimmune disorders; 1 patient with Crohn´s Diseases, 1 case of autoimmune thrombocytopenic purpura, and a patient with Vogt-Koyanagi-Harada syndrome (non-granulomatous uveitis). Conclusions: There is a broad range of clinical manifestations in pediatric HTLV-1 patients, and the clinician should consider structural pulmonary disease, opportunistic co-infections and autoimmune disorders in the diagnostic algorithm.

ABSTRACT

Introdução: Vírus Linfotrópico de Células T Humana do Tipo-1 (HTLV-1) é um retrovírus que afeta os linfócitos T humano e desencadeia inflamação na medula, levando à paraparesia espástica tropical/mielopatia associada ao HTLV-1 (PET/MAH) com prejuízos funcionais. Tais disfunções podem influenciar nos efeitos da fisioterapia, gerando diferentes níveis de fadiga. Objetivo: Avaliar a percepção subjetiva de esforço e de recuperação de indivíduos com PET/MAH após sessão única de fisioterapia. Métodos: Incluíram-se 12 participantes sintomáticos para PET/MAH, de ambos os sexos, que foram submetidos uma vez ao protocolo fisioterapêutico. Os instrumentos avaliativos foram: Escala Modificada de Borg, Escala de Percepção Subjetiva de Recuperação (1º, 5º e 10º minuto após a sessão) e Escala de Incapacidade Neurológica do Instituto de Pesquisa Clínica Evandro Chagas ­ 2 (EIPEC). Resultados: Encontrou-se correlação moderada entre idade e taxa de percepção subjetiva de recuperação ao 1º (r = - 0,4923) e 5º (r = - 0,4913) minuto e entre índice do EIPEC-2 e taxa de percepção subjetiva de recuperação ao 1º (r = 0,3592) e 5º (r = - 0,3772) minuto. Conclusão: Indivíduos deste estudo com maior idade e grau de incapacidade neurológica têm menor percepção subjetiva de recuperação. (AU)


Introduction: Human T-Cell Lymphotropic Virus Type-1 (HTLV-1) is a retrovirus that affects human T lymphocytes and triggers inflammation in the spinal cord, leading to tropical spastic paraparesis / HTLV-1 associated myelopathy (TSP/HAM) with functional impairments. Such dysfunctions can influence the effects of physical therapy, generating different levels of fatigue. Objective: To evaluate the subjective perception of effort and recovery of individuals with TSP/HAM after a single session of physical therapy. Methods: 12 symptomatic participants for TSP/HAM, of both sexes, who were submitted once to a physiotherapeutic protocol were included. The evaluative instruments were: Modified Borg Scale, Scale of Subjective Perception of Recovery (1st, 5th and 10th minute after the session) and Scale of Neurological Disability at the Evandro Chagas Clinical Research Institute - 2 (EIPEC). Results: A moderate correlation was found between age and subjective perception rate of recovery at the 1st (r = - 0.4923) and 5th (r = - 0.4913) minute and between the EIPEC-2 index and the subjective perception rate of recovery at the 1st (r = 0.3592) and 5th (r = - 0.3772) minute. Conclusion: Individuals in this study with older age and degree of neurological disability have less subjective perception of recovery. (AU)

ABSTRACT

O HTLV é um retrovírus que afeta os linfócitos T humanos. Sua forma de transmissão é por via hematogênica, sexual ou vertical. A maioria das pessoas infectadas são portadores assintomáticos, porém, algumas podem vir a desenvolver quadros graves como a paraparesia espástica tropical, leucemia/linfoma, dentre outras manifestações. O Brasil é considerado o país com o maior número absoluto de casos, com estimativa de 800 mil infectados. Este artigo teve como objetivo conhecer e analisar o processo de introdução do HTLV na agenda governamental nos estados da Bahia e Minas Gerais, que repercutiu em ações e políticas setoriais. Foram realizadas entrevistas com atores-chave e pesquisa documental, e para análise utilizamos como principal referencial o modelo Múltiplos Fluxos de John Kingdon. Constatamos que vários fatores contribuíram para inclusão do tema na agenda da Bahia, estado com maior abrangência das políticas voltadas ao HTLV, tais como alta prevalência da infecção, contexto político favorável e militância de indivíduos vivendo com HTLV. Em Minas Gerais observamos dificuldades para implementação de política setorial e que a inexistência de grupos organizados reverteu negativamente para que o problema não fosse uma prioridade para as Secretarias de Saúde no estado. Na atual conjuntura, indivíduos infectados pelo HTLV e outros atores envolvidos com o tema ainda possuem um longo caminho a percorrer na mobilização social para investimentos na área, para a formulação e implementação de políticas públicas e conquista de direitos sociais.


HTLV is a retrovirus that affects the human T-lymphocytes. Transmission is bloodborne, sexual, or mother-to-child. Most infected persons are asymptomatic carriers, but some may develop severe cases such as tropical spastic paraparesis, leukemia/lymphoma, and other manifestations. Brazil is considered the country with the highest absolute number of cases, with an estimated 800,000 infected individuals. This article aimed to investigate and analyze the process of inclusion of HTLV on the government agenda in the states of Bahia and Minas Gerais, and which impacted health sector actions and policies. Interviews were held with key actors, and a document search was performed for analysis, using as the main reference the Multiple Streams framework proposed by John Kingdon. Various factors contributed to the theme's inclusion on the health sector agenda in Bahia, the state of Brazil with the widest range of policies on HTLV, involving high prevalence of the infection, a favorable political context, and activism by infected individuals. In Minas Gerais, we observed difficulties in the implementation of this health sector policy; due to the lack of organized advocacy groups, the problem was not a priority in the state's Health Departments. In the current context, individuals with HTLV infection and other stakeholders still have a long road ahead with social mobilization for investments in the area, drafting and implementation of public policies, and guarantee of social rights.

ABSTRACT

Abstract INTRODUCTION: Individuals with human T-cell lymphotropic virus 1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) experience sensorimotor alterations, which can affect functional performance. Virtual reality (VR) videogaming is a therapeutic option, though there is scarce evidence for its use in this population. We aimed to investigate the therapeutic effects of a VR video game on functional mobility, balance, and gait speed in individuals with HAM/TSP. METHODS: We conducted a blinded, crossover clinical trial comprising 29 individuals with HAM/TSP and randomized them into two groups: (1) early therapy: rehabilitative protocol started immediately after the initial evaluation and (2) late therapy: rehabilitative protocol started 10 weeks later. We assessed all participants for balance using the Berg Balance Scale (BBS) scores, functional mobility using the Timed Up and Go (TUG) test, and gait speed using video camera and CvMob software. Differences were considered significant if p<0.05. RESULTS: The early therapy group individuals presented with higher BBS scores (p=0.415), less TUG times (p=0.290), and greater gait speed (p=0.296) than the late therapy group individuals. CONCLUSIONS: VR videogaming is a useful option for rehabilitative therapy in individuals with HAM/TSP; it positively affects balance, functional mobility, and gait speed.

ABSTRACT

Resumen Introduccion: La infección con el virus linfotrópico de células T humano (HTLV) de tipo 1 y 2 es endémica en América del Sur. Existen muy pocos reportes clínicos de este retrovirus en pacientes de Ecuador y nunca confirmaron la presencia del virus con el aislamiento o la detección de su ADN. Esta infección se encuentra desatendida por las autoridades de salud pública, sin que existan estudios epidemiológicos de prevalencia a nivel del país. Objetivos: Este estudio tiene como objetivo la detección de infección por HTLV -1/2 en individuos sintomáticos de paraparesis espástica tropical (TSP) utilizando por primera vez en Ecuador diagnóstico serológico y la detección del provirus por biología molecular. Diseño del estudio. Se tomaron muestras de nueve pacientes con un diagnóstico de mielopatía y sospechoso de TSP, que fueron analizadas para la detección del virus HTLV-1/2 usando tres metodologías: ELISA comercial, ensayo de inmunofluorescencia indirecta (IF) y PCR anidada. Resultados: Cinco de los 9 (55.5%) pacientes fueron positivos tanto para la prueba de ELISA como para IF y PCR anidada. Conclusión: La alta prevalencia de infección por HTLV-1/2 entre individuos sintomáticos de mielopatía muestra la endemicidad de este retrovirus en Ecuador, la asociación de HTLV-1/2 con TSP y la necesidad de implementar estrategias de control y prevención para evitar la diseminación de esta enfermedad infecciosa desatendida.


Abstract Background: Infection with the Human T-cell lymphotropic virus (HTLV) type 1 and 2 is endemic in South America. There are only a few clinical reports of this retrovirus in patients in Ecuador, without employing virus-isolation methods or viral DNA detection. The infection is usually neglected in health care settings and by public health authorities and no country wide prevalence data are available. Objectives: This study aims to detect the HTLV-1/2 infection in symptomatic individuals for tropical spastic paraparesis (TSP) using for the first time in Ecuador both immunological and molecular biology methodologies. Study Design: Blood samples of 9 symptomatic individuals with myelopathy were analyzed for the detection of the HTLV-1/2 virus with three methods: ELISA, an indirect immunofluorescence (IF) assay and a nested-PCR. Results: Five out of 9 (55.5%) myelopathy patients were positive for ELISA, IF and nested- HTLV-1/2 PCR. Conclusion. The high prevalence of HTLV-1/2 infection among myelopathy patients shows the endemicity of this retrovirus in Ecuador, the association of HTLV-1/2 infection with TSP and the need of the implementation of control and prevention interventions to overcome the further dissemination of this neglected infectious disease.

ABSTRACT

Abstract Background: Physical therapy has positive results in people with tropical spastic paraparesis (TSP). However, mobility and distance from rehabilitation centers limit the participation in outpatient programs. Objective: To evaluate the impact of a home exercise program on the posture and functional mobility of people with TSP. Methods: A randomized controlled trial comparing three groups of people who performed guided exercises from a guidebook for six months: supervised (SG), unsupervised (WG), and control (CG). Primary outcomes: postural angles (SAPO®) and functional mobility (TUG). Secondary outcomes: gait parameters (CVMob®). Results: The protocol described in the guidebook improved postural angles and functional mobility. There were also positive gait parameter effects (p<0.05). SG presented better responses than WG did, but both were preferable to CG. Conclusion: Home exercises oriented by a guidebook may benefit posture, functional mobility and gait parameters in people with TSP, and physiotherapist supervision can ensure better results.


Resumo Introdução: A fisioterapia apresenta resultados positivos em pessoas com paraparesia espástica tropical (PET). Entretanto, a dificuldade de locomoção e a distância dos centros de reabilitação limitam a participação em programas ambulatoriais. Objetivo: Avaliar o impacto de um programa de exercícios domiciliares na postura e mobilidade funcional de pessoas com PET. Métodos: Um ensaio clínico randomizado comparou três grupos de pessoas que realizaram exercícios guiados por cartilha: com supervisão (GS), sem supervisão (GN) e controle (GC) durante seis meses. Desfechos primários: ângulos posturais (SAPO®) e mobilidade funcional (TUG). Desfechos secundários: parâmetros da marcha (CVMob®). Resultados: O protocolo descrito na cartilha melhorou os ângulos posturais e a mobilidade funcional. Os resultados também foram positivos para os parâmetros da marcha (p<0,05). O GS apresentou melhores respostas que o GN, porém ambos foram preferíveis ao GC. Conclusão: Exercícios domiciliares orientados por cartilha podem ser úteis para beneficiar a postura, mobilidade funcional e parâmetros de marcha em pessoas com PET, e a supervisão do fisioterapeuta possibilita garantir melhores resultados.

ABSTRACT

Abstract Introduction: Postural control in individuals with HTLV-1-associated myelopathy or tropical spastic paraparesis (HAM/TSP) is usually compromised, which increases the risk of falls, makes it difficult to perform activities of daily living, and impairs the quality of life. The profile of the center of gravity oscillations in this population is unknown and may aid in clinical follow-up and research. Objective: To compare the stabilometric values between HAM/TSP and uninfected individuals and verify the existence of correlations between stabilometric variables and the Berg Balance Scale (BBS). Method: A cross-sectional observational study was performed with infected individuals, classified as defined and likely (WHO criteria), compared to accompanying persons and seronegative relatives. A baropodometry platform (Footwork®) was used to obtain the oscillation values of the body's center of gravity in total oscillation area (TOA), anterior-posterior oscillation (APO) and lateral oscillation (LO). Mean values were correlated with BBS by Spearman's Correlation (5% alpha). Approved by the ethical committee of Escola Bahiana de Medicina e Saúde Pública under Opinion 49634815.2.0000.5628. Results: An asymmetric distribution of all the stabilometric variables analyzed in the HAM/TSP population was found, different from the uninfected group (p < 0.05). It was also possible to verify strong to moderate and inverse correlations between the variables of center of gravity oscillation with the scores obtained in BBS, especially for TOA and LO. Conclusion: People with HAM/TSP presented higher values for the center of gravity oscillations and these were correlated with the BBS in the balance evaluation.


Resumo Introdução: o controle postural em indivíduos com mielopatia associada ao HTLV-1 ou paraparesia espástica tropical (HAM/TSP) é geralmente comprometido, o que aumenta o risco de quedas, dificulta a realização de atividades de vida diária e prejudica a qualidade de vida. O perfil das oscilações do centro de gravidade nesta população é desconhecido e pode auxiliar no acompanhamento clínico e na pesquisa. Objetivo: comparar os valores estabilométricos entre pessoas com HAM/TSP e não infectados, e verificar a existência de correlações entre variáveis estabilométricas e a Escala de Equilíbrio Berg (EEB). Método: foi realizado um estudo observacional transversal com indivíduos infectados, classificados como definidos e prováveis (critérios da OMS), comparados com acompanhantes e familiares soronegativos. Uma plataforma de baropodometria (Footwork®) foi utilizada para obter os valores de oscilação do centro de gravidade do corpo em área de oscilação total (AOT), oscilação anteroposterior (OAP) e oscilação laterolateral (OLL). Os valores médios foram correlacionados com a BBS pela Correlação de Spearman (alfa 5%). Aprovado pelo Comitê de Ética da Escola Bahiana de Medicina e Saúde Pública sob o CAAE 49634815.2.0000.5628. Resultados: encontrou-se distribuição assimétrica de todas as variáveis estabilométricas analisadas na população com HAM/TSP, diferentes do grupo de não infectados (p < 0,05). Também foi possível verificar correlações de forte a moderada e inversas entre as variáveis de oscilação do centro de gravidade com os escores obtidos na EEB, especialmente para AOT e OLL. Conclusão: Pessoas com HAM/TSP apresentaram valores maiores para as oscilações do centro de gravidade e estas foram correlacionadas com a EEB na avaliação do equilíbrio.

ABSTRACT

Abstract INTRODUCTION: A good rating of the device in people with HTLV-1 in this population is essential for accuracy in prescribing data (walking). Thus, this study aimed to analyze the counterpart assessment methods that are best suited to patients with human T-cell lymphotropic virus (HTLV)-1 associated myelopathy or tropical spastic paraparesis (HAM/TSP). METHODS: This cross-sectional study related stabilometric and kinematic variables of postural oscillations with Berg's balance scale (BBS) and Timed Up and Go (TUG) in subjects with HAM/TSP compared to asymptomatic subjects. To assess the posterior and lateral postural projection, baropodometry and the Footwork® system was used, and the CVMob system was applied to kinematic parameters. The means comparison tests and correlations were applied with an alpha of 5%. RESULTS: Thirty-nine subjects (predominantly female) made up the sample. There was an increase in barodopometric oscillations, in the total oscillation area (p = 0.004), in the anteroposterior oscillation in the left (p = 0.015) and right views (p = 0.036), and in the lateral oscillation (p = 0.039) in the HAM/TSP group. Moderate correlations were found between oscillation baropodometry and the angular variation of the ankle, as well as with the BBS in the three angles and the TUG for lateral oscillation (p = 0.406). CONCLUSIONS: Each method has advantages and disadvantages, including cost accuracy. The best resources available at no additional cost for outpatient to use are the kinematic evaluation using a simple smartphone camera and free analysis software, and the TUG.

ABSTRACT

Abstract INTRODUCTION In patients with HTLV-1 associated myelopathy/tropical spastic paraparesis (HAM/TSP) gait disturbance is a predominant feature that leads to falls and fractures, which can further aggravate disability. We sought to evaluate the impact of fractures and orthopedic surgeries in patients with HAM/TSP. METHODS: We retrieved the medical records of HAM/TSP patients enrolled in our study center's HTLV-1 clinical cohort between 1989-2018. The selection criteria included: (1) diagnosis of HTLV-1 infection using two enzyme-linked immunosorbent assays and/or a confirmatory test, (2) clinical diagnosis of HAM/TSP by neurological assessment, and (3) fractures associated with HAM/TSP. RESULTS: We identified 24 cases of fractures, 70% of which were females. The median age at the time of fracture was 60 years (IQR=24). Six cases reported fractures in patients under 45 years old. Ten patients (42%) had hip/coccyx fractures, seven (29%) were in the lower extremities, and four (17%) in the upper extremities. Half of these patients reported the use of wheelchairs. Five patients who had previously used canes required the use of wheelchairs after the reported fracture. Eight patients underwent corrective orthopedic surgery as a result of the fracture. CONCLUSIONS: For HAM/TSP patients, fractures are a complication that can exacerbate their severe impairment.

ABSTRACT

The human T-cell lymphotropic virus type 1 (HTLV-1) is a retrovirus that infects about 20 million people worldwide and causes immune-mediated diseases of the nervous system. The classical neurological presentation of HTLV-1 infection is the so-called HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP). However, HAM/ TSP is not the only neurological outcome that can result from HTLV-1 infection. In this Review it is made an update on the many aspects of this important neurological condition, the HTLV-1 neurological complex.


O vírus linfotrópico de células T humanas tipo 1 (HTLV-1) é um retrovírus que infecta cerca de 20 milhões de pessoas em todo o mundo e causa doenças imunomediadas do sistema nervoso. A apresentação neurológica clássica da infecção pelo HTLV-1 é a chamada paraparesia espástica tropical / mielopatia associada ao HTLV-1 (HAM/TSP). HAM / TSP,no entanto, não é o único desfecho neurológico que pode resultar da infecção pelo HTLV-1. Nesta revisão, é feita uma atualização sobre vários aspectos desta importante condição neurológica, o complexo neurológico do HTLV-1.

ABSTRACT

Resumen Antecedentes: El virus linfotrópico T tipo I (HTLV-I) origina la paraparesia espástica tropical (PET) en el 3% de los infectados, afectando predominante mujeres. Excepcionalmente la PET puede asociar un síndrome vestibular central y atrofia cerebelosa. Propósito: Presentar un nuevo y excepcional caso de paraparesia espástica y atrofia cerebelosa. Sugerir una interpretación patogénica del predominio femenino en esta patología Paciente: Mujer de 20 años de talla baja y menuda, infectada con HTLV-I durante la lactancia. Aproximadamente a los 15 años inició un síndrome ataxo-espástico progresivo, con grave alteración de la marcha, posteriormente agregó daño cognitivo y atrofia cerebelosa en la RM. Se constató a su ingreso una elevada carga viral y altos niveles de proteína Tax. Fue tratada con 4 mg betametasona diarios durante 10 días, que mejoraron la marcha. Conclusión: La PET es una axonopatía de la vía motora central, originada por la crónica perturbación del transporte axoplásmico, atribuible a la presencia de elevados niveles de la proteína Tax del virus. Circunstancialmente este aumento de Tax logra dañar axones del centro oval (deterioro cognitivo) o del vermis cerebeloso (síndrome vestibular central). La PET afecta mayoritariamente a mujeres 3:1, prevalencia que hace aparecer a las mujeres con una mayor vulnerabilidad en su SNC. Sin embargo, esta aparente minusvalía, sería debida a un aumento en la concentración de Tax en el SNC de ellas, causado por la adversa relación entre peso corporal y cantidad absoluta de Tax, que fue evidente en nuestra paciente, quien dio la clave para esta hipótesis.


Background: Lymphotropic Virus Type I (HTLV-I) causes Tropical Spastic Paraparesis (PET) in 3% of infected patients; in whom have been described exceptionally associated a central vestibular syndrome and cerebellar atrophy. Those alterations of CNS are predominating in women. Purpose: To present a new case of the exceptional form of spastic paraparesis and cerebellar atrophy. To suggest a pathogenic interpretation of female predominance in this pathology Patient: A 20-year-old woman of small size, infected with HTLV-I during lactation. Approximately at 15 years of age he started a progressive ataxo-spastic syndrome, later cognitive damage and cerebellar atrophy were added. Upon admission, high viral load and high levels of Tax protein, leukemoid lymphocytes and Sicca syndrome were observed. Conclusion: PET is an axonopathy of the central motor pathway, originated by a chronic disturbance of axoplasmic transport, attributable to the action of elevated levels of Tax protein in the CNS. In addition axons of the oval center (cognitive impairment) or the cerebellar vermis (central vestibular syndrome) are occasionally damaged. Although PET mainly affects 3: 1 women, this prevalence increases in accordance with the increase of neurological damage. The apparent greater vulnerability of the CNS in women would be due to the higher concentration of Tax in the CNS of them, originated in the adverse relationship between body weight and absolute amount of Tax, which was evident in our patient, who gave the key to this hypothesis.

ABSTRACT

INTRODUÇÃO: A marcha de pessoas com Mielopatia Associada ao HTLV-1 ou Paraparesia Espástica Tropical (HAM/TSP) é pouco conhecida. OBJETIVO: Avaliar o perfil cinemático da marcha em pessoas com HAM/TSP. MÉTODOS: Estudo transversal com 25 pessoas com HAM/TSP e 25 participantes saudáveis. Os dados espaço-temporais e angulares das filmagens da marcha foram submetidos à análise cinemática utilizando o software CVMob®. A marcha dos participantes com HAM/TSP foi analisada quantitativamente através do teste t-student (alfa de 5% e poder de 80%). O projeto foi aprovado pelo comitê de ética da Escola Bahiana de Medicina e Saúde Pública sob o CAAE 13568213.8.0000.5544. RESULTADOS: O grupo HAM/TSP apresentou alterações significativas em dois domínios distintos da análise biomecânica da marcha quando comparados aos controles saudáveis. As variáveis angulares apresentaram maior inclinação, flexão e extensão do tronco (p <0,05); aumento da flexão do quadril e diminuição da extensão do quadril (p <0,05); diminuição da flexão e extensão do joelho (p <0,05); diminuição da flexão dorsal e plantar do tornozelo (p <0,05). A amplitude de movimento também foi reduzida em todas essas articulações. As variáveis espaço-temporais mostraram diminuição do comprimento da passada, aumento do tempo da passada e velocidade do ciclo da marcha (p <0,001). Essas mudanças apontam para redução nas amplitudes articulares do quadril, joelho e tornozelo, mudanças na base de apoio e assimetria do tempo do duplo apoio entre os lados direito e esquerdo, redução do tempo do pré-balanço, elevação do quadril no balanço médio e queda do pé ao longo do balanço. CONCLUSÃO: As pessoas com HAM/TSP apresentam marcha caracterizada por redução nas amplitudes articulares do quadril, joelho e tornozelo, assimetria do tempo de suporte duplo entre os lados direito e esquerdo, redução do tempo do pré-balanço, elevação do quadril no balanço médio e queda do pé ao longo do balanço.


INTRODUCTION: The gait in people with HTLV-1 Associated Myelopathy or Tropical Spastic Paraparesis (HAM / TSP) is little known. OBJECTIVE: To evaluate the kinematic profile of gait in people with HAM/ TSP. METHODS: A cross-sectional study with 25 people with HAM/TSP and 25 healthy participants. Spatiotemporal and angular data from filming of gait were submitted to kinematic analysis using CVMob® software. The gait of partipants with HAM/TSP was analized quantitatively through t Student test (alpha 5% and Power of 80%). The project was approved by Ethical Committee of the Bahiana School of Medicine and Public Health with CAAE 13568213.8.0000.5544. RESULTS: The HAM/TSP group showed significant changes in two different domains of biomechanical gait analysis when compared to healthy controls. The angular variables showed increased trunk inclination, flexion and extension (p<0.05); increased hip flexion and decreased hip extension (p<0.05); decreased knee flexion and extension (p<0.05); decreased ankle dorsi and plantar flexion (p<0.05). Range of Motion was also reduced in all those joints. The spatiotemporal variables showed decreased stride length, increased stride time and speed gait cycle (p<0.001). Those changes point out to reduction in joint amplitudes of hip, knee and ankle, changes in support base and double support time asymmetry between right and left sides, reduction of pre-swing time, hip lift in the mid-swing, and foot drop throughout the swing. CONCLUSION: People with HAM/TSP have gait characterized by reduction in joint amplitudes of hip, knee and ankle, asymmetry between right and left sides and reduction of pre-swing time, hip lift in the mid-swing, and foot drop throughout the swing.

ABSTRACT

Resumo: O HTLV é um vírus que afeta as células T humanas. O Brasil é o país com o maior número absoluto de casos de HTLV no mundo. Estimativas do Ministério da Saúde apontam entre 700 mil e 2 milhões de pessoas infectadas. A maioria são portadores assintomáticos, porém algumas pessoas podem vir a desenvolver quadros neurológicos degenerativos como a paraparesia espástica tropical, além de leucemia e linfoma. As formas de transmissão e manifestações clínicas como incapacidade motora progressiva, distúrbios geniturinários, além da restrição ao aleitamento materno impactam o cotidiano e podem ser geradores de discriminação social e estigma. O estigma denota violação das normas sociais e reforça o preconceito e as desigualdades. O objetivo deste artigo é discutir o conceito de estigma e sua repercussão em pessoas que convivem com o HTLV. Trata-se de uma reflexão baseada na revisão da literatura sobre o tema e na vivência do atendimento a pessoas afetadas pela infecção e adoecimento. Constatou-se que ser portador do vírus ou adoecer em decorrência da infecção pelo HTLV pode ser estigmatizante para indivíduos que se sentem inferiorizados ao serem acometidos por uma doença potencialmente grave e até mesmo fatal, ainda pouco conhecida e carregada de estereótipos depreciativos. Essa situação pode repercutir negativamente no acesso aos serviços de saúde, na adesão ao tratamento e na busca por direitos. As políticas públicas devem contribuir para mitigar a estigmatização, assegurando o direito de indivíduos em situação de vulnerabilidade pelo HTLV viverem como protagonistas no exercício de sua cidadania.


Resumen: El HTLV es un virus que afecta a las células T humanas. Brasil es el país con el mayor número absoluto de casos de HTLV en el mundo. Las estimaciones del Ministerio de Salud indican que existen entre 700 mil y 2 millones de personas infectadas. La mayoría son portadores asintomáticos, sin embargo, algunas personas pueden llegar a desarrollar cuadros neurológicos degenerativos como la paraparesia espástica tropical, además de leucemia y linfoma. Las formas de transmisión y manifestaciones clínicas como incapacidad motora progresiva, disturbios genitourinarios, además de la restricción en la lactancia materna, tienen un impacto en las personas afectadas y pueden causar discriminación social y estigma. El estigma denota una violación de las normas sociales y refuerza el prejuicio y las desigualdades. El objetivo de este artículo es discutir el concepto de estigma y su repercusión en personas que conviven con el HTLV. Se trata de una reflexión basada en la revisión de la literatura sobre el tema y en la vivencia de la atención a personas afectadas por la infección y enfermedad. Se constató que ser portador del virus o enfermar, a consecuencia de la infección por el HTLV, puede ser estigmatizante para individuos que se sienten subestimados al ser atacados por una enfermedad potencialmente grave e incluso fatal, todavía poco conocida y cargada de estereotipos despreciativos. Esta situación puede repercutir negativamente en el acceso a los servicios de salud, en la adhesión al tratamiento y en la búsqueda de derechos. Las políticas públicas deben contribuir a mitigar la estigmatización, asegurando el derecho de los individuos en situación de vulnerabilidad por el HTLV para que vivan como protagonistas en el ejercicio de su ciudadanía.


Abstract: HTLV is a virus that affects human T-cells. Brazil is the country of the world with the largest absolute number of HTLV cases. Estimates by the Ministry of Health point to 700,000 to 2 million infected Brazilians. The majority are asymptomatic carriers, but some persons may develop degenerative neurological conditions such as tropical spastic paraparesis, in addition to leukemia and lymphoma. The forms of transmission and clinical manifestations such as progressive motor incapacity, genitourinary disorders, in addition to restriction of maternal breastfeeding, impact daily life and can lead to social discrimination and stigma. The stigma denotes violation of social norms and reinforces prejudice and inequalities. This article aims to discuss the concept of stigma and its repercussions on persons living with HTLV. The discussion is based on a literature review on the theme and the authors' experience with care for persons affected by the infection and illness. The study found that both HTLV carrier status and HTLV-related illness can be stigmatizing for individuals, who feel inferior for being infected with a potentially serious and even fatal disease, although incompletely understood and loaded with derogatory stereotypes. This situation can have negative repercussions on access to health services, treatment adherence, and pursuit of rights. Public policies should help mitigate such stigmatization, ensuring the rights of individuals in a situation of vulnerability due to HTLV in order from them to live as protagonists in the exercise of their civil rights.

ABSTRACT

Abstract INTRODUCTION: Human T-cell lymphotropic virus type 1-associated myelopathy or tropical spastic paraparesis (HAM/TSP) causes, among other abnormalities, chronic pain that may impair quality of life (QOL). Home protocols can help those who have difficulty attending rehabilitation centers. This study aimed to evaluate the impact of a home-based exercise protocol on pain and QOL in people with HAM/TSP. METHODS: A randomized clinical trial of people with HAM/TSP (World Health Organization criteria) classified as probable or definite. The supervised group (SG) underwent training for 12 weeks and continued the protocol at home for another 12 weeks; the unsupervised group (UG) performed the same protocol at home without physical therapist supervision for 24 weeks; and the control group (CG) maintained the usual care. QOL was assessed by the Short Form-36 health survey and the pain condition by the Brief Pain Inventory (BPI). The Chi-square, analysis of variance, Kruskal-Wallis, and Friedman tests (5% alpha) were used for the analyses. The intention-to-treat method was adopted in case of follow-up losses. Record number RBR-849jyv/UTN: U1111-1176-2858. RESULTS: Of 56 participants, 49 completed the protocol. Mean pain was moderately reduced (>30%) in the UG and CG and mildly reduced (20%) in the SG. Loss in the vitality score of QOL in the CG was noted. CONCLUSIONS: The protocol generated mild and moderate pain relief and reduced losses in the functional QOL in the treatment groups.

ABSTRACT

Abstract INTRODUCTION: Tropical spastic paraparesis/HTLV-1 associated myelopathy (TSP/HAM) is a disease caused by human T-cell lymphotropic virus type 1 (HTLV-I) that mainly infects CD4 T cells-for example, those of the CD4+CD25hiFOXP3+ [Treg] phenotype-where it inhibits forkhead box protein P3 (FOXP3) expression and promotes interferon-γ (IFN-γ) expression. However, the role it exerts on regulatory B cells (CD19+CD24hiCD38hi; Breg) is unknown. METHODS: The frequencies of Treg and Breg cells was evaluated and the Th1 profiles were assessed in TSP/HAM patients and healthy control subjects. RESULTS: Low percentages of Breg cells and high production of IFN-γ were observed in patients compared to those in healthy control subjects. CONCLUSIONS: The low percentage of Breg cells in patients and the increase in the frequency of Th1 cells suggest an imbalance in the control of the inflammatory response that contributes to the immunopathogenesis of TSP/HAM.

ABSTRACT

Abstract An HTLV-1-infected patient can develop paraparesis that limits their movements. Rehabilitation techniques could improve the motor abilities of these patients. The present study investigates five cases of physical therapy intervention in HTLV-1 patients to evaluate the influence of functional rehabilitation on the tonus and range of motion (ROM) of HTLV-1 patients with spasticity. The patients had a gain of ROM, especially in the lower limb, and reduction in hypertonia/spasticity after functional treatment. The reduction in hypertonia increased the ROM. Thus, functional methods may be valuable for the rehabilitation of HTLV-1 patients with neurological damage.

ABSTRACT

A estrongiloidíase é uma enfermidade que acomete cerca de 100 milhões de pessoas em todo mundo. Essa parasitose apresenta alta prevalência e tem maior gravidade clínica entre indivíduos imunossuprimidos, principalmente aqueles portadores do vírus linfotrópico de células T humana tipo 1 (HTLV). Este fato torna a coinfecção por esse vírus em pacientes parasitados por Strongyloides stercoralis um grave problema de saúde pública. O presente estudo teve por objetivo revisar os estudos sobre coinfecção por HTLV/S. stercoralis. Foi realizada busca eletrônica completa de dados disponíveis sobre a coinfecção entre o vírus e S. stercoralis. As publicações foram capturadas a partir das bases de dados PubMed e SciELO, sendo utilizados os seguintes descritores "vírus linfotrópico de células T humanas tipo 1", "HTLV-1", "S. stercoralis" e "estrongiloidiase". A infecção por HTLV em pacientes parasitados representa fator de risco para o desenvolvimento de estrongiloidíase grave e, nesses indivíduos, o tratamento recomendado deve ser realizado e monitorado para garantir o sucesso terapêutico.(AU)


Strongyloidiasis is a disease that affects approximately 100 million people worldwide. This parasitosis is highly prevalent and more clinically severe among immunosuppressed individuals, particularly those with Human T-lymphotropic virus 1 (HTLV-1). This fact makes the co-infection with this virus in patients parasitized by Strongyloides stercoralis a serious public health problem. The present study aimed at reviewing the studies of co-infection with HTLV/S. stercoralis. A complete electronic search for available data about the co-infection of the virusand S. stercoralis was performed. The publications were obtained from the databases PubMed and SciELO, with the following descriptors being used: "Human T-lymphotropic Virus type 1, "HTLV-1", S. stercoralis, and "strongyloidiasis". The infection with HTLV in infected patients is a risk factor for the development of severe strongyloidiasis, and for these individuals the recommended treatment should be performed and monitored to ensure therapeutic success.(AU)

ABSTRACT

Abstract INTRODUCTION: Human T-cell lymphotropic virus type 1 (HTLV-1)induces exaggerated Th1 responses, whereas atopy is associated with exacerbated Th2 responses. METHODS: Here, a cross-sectional study compared the prevalence of atopy in HTLV-1 carriers and HAM/TSP patients. It also compared the spontaneous cytokine production in HTLV-1-infected individuals. A retrospective cohort study evaluated the development of neurological manifestations in atopic and non-atopic carriers. RESULTS: Atopic HAM/TSP patients with high IFN-γ production exhibited higher IL-5 levels than non-atopic patients. Allergic rhinitis accelerated the development of Babinski signals and overactive bladders. CONCLUSIONS: Abnormal Th1 and Th2 responses coexist in HTLV-1-infected individuals and allergic diseases may worsen the clinical course of HTLV-1 infections.

ABSTRACT

Abstract INTRODUCTION: Human T-cell lymphotropic virus type-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) may lead to reduced functional mobility and balance. It is important to establish specific parameters that identify these changes and predict the risk of falls in these patients. The aim was to compare balance, functional mobility, and occurrence of falls among patients with and without HAM/TSP and to suggest values to predict the risk of falls in these patients. METHODS: A cross-sectional study in patients with and without HAM/TSP involved balance assessments based on the berg balance scale (BBS) and functional mobility evaluation based on the timed up and go (TUG) test. From reports of falls, the sensitivity, specificity, and best cutoff points for the risk of falls assessed by these instruments were established using the receiver-operating characteristic (ROC) curve; 5% alpha was considered. RESULTS: We selected 42 participants: 29 with HAM/TSP and 13 without HAM/TSP. There was a statistically significant difference in the occurrence of falls, balance, and functional mobility between the groups (p<0.05). Good accuracy was determined for the BBS (77%) and TUG test (70%) and the cutoff points for the risk of falls were defined as 50 points for the BBS and 12.28 seconds for the TUG test. CONCLUSIONS: Patients with HAM/TSP present reduced functional mobility and balance in relation to those without HAM/TSP. The risk of falls increased for these patients can be evaluated by the values ​​of 50 points using the BBS and 12.28 seconds using the TUG test.

ABSTRACT

Abstract Introduction HTLV-1 infection is endemic in Japan, Caribbean, Africa, and South America. It is transmitted from mother to child, sexual contact, blood transfusions, or sharing needles. Tropical spastic paraparesis (TSP) is a chronic degenerative neurological disease associated with this infection. It results from a spinal cord symmetrical degeneration at the thoracic level and is characterized by progressive motor weakness in the lower limbs, hyperreflexia, sensitivity changes, urinary incontinence, and bladder dysfunction. Clinical case Female, 53 years old, HTLV-1 infection and TSP. She had decreased strength in the lower limbs and hyperreflexia, paretic gait, spasticity, and neurogenic bladder symptoms, with recurrent urinary infections. She was scheduled for cystectomy. The patient was monitored according to standard ASA. Due to severe coagulopathy and the possibility of neurological worsening, epidural catheter was not placed. The induction of general anesthesia was performed with midazolam and fentanyl, followed by etomidate and cisatracurium. She was intubated with a tube size seven and maintained with desflurane and oxygen. Anesthesia was uneventful; the surgery lasted 1 hour and 50 min. There were no complications in the immediate postoperative period, during hospitalization, nor deterioration of the neurological examination. The patient was discharged 20 days later. Discussion/Conclusion There are reports of decreased electromyographic response and neurological deterioration associated with propofol in these patients, etomidate was used. The hepatic metabolism of rocuronium posed a risk, we chose to use cistracurium. It was concluded that the anesthesia chosen did not affect the course of the disease.


Resumo Introdução A infecção por HTLV- 1 é endêmica no Japão, nas Caraíbas, na África e na América do Sul. A transmissão ocorre de mãe para filho, por contatos sexuais, transfusões de sangue ou partilha de agulhas. A essa infeção está associada uma doença neurológica degenerativa crônica, a paraparesia espástica tropical (TSP). Essa resulta de uma degeneração simétrica da espinal medula em nível torácico. Caracteriza-se por diminuição progressiva da força nos membros inferiores, hiperreflexia, alterações de sensibilidade, incontinência urinária e disfunção vesical. Caso clínico Mulher de 53 anos, infecção por HTLV-1 e TSP. Apresentava diminuição da força nos membros inferiores e hiperreflexia, tinha uma marcha parética, espasticidade e sintomas de bexiga neurogênica com infecções urinárias de repetição. Foi proposta para cistectomia. Foi monitorada de acordo com o padrão da ASA. Devido à coagulopatia grave e à possibilidade de agravamento neurológico, não se colocou cateter epidural. A indução da anestesia geral foi feita com midazolam e fentanil seguidos de etomidato e cisatracúrio. Foi entubada com um tubo sete e mantida com desflurano e oxigênio. A anestesia decorreu sem intercorrências, a cirurgia terminou em uma hora e 50 minutos. Não houve quaisquer complicações no pós-operatório imediato, durante a internação, nem deterioração do exame neurológico. A doente teve alta 20 dias depois. Discussão/Conclusão Há relatos de diminuição da resposta eletromiográfica e deterioração neurológica associadas ao propofol nesses doentes, razão para uso de etomidato. A metabolização hepática do rocurônio representava um risco e se optou pelo cisatracúrio. Conclui-se que o plano anestésico escolhido não teve qualquer interferência no curso da doença.
