ABSTRACT BACKGROUND: The cause of oropharyngeal dysphagia in patients with coronavirus disease (COVID-19) can be multifactorial and may underly limitations in swallowing rehabilitation. OBJECTIVE: Analyze the factors related to dysphagia in patients with COVID-19 immediately after orotracheal extubation and the factors that influence swallowing rehabilitation. DESIGN AND SETTING: A retrospective study. METHODS: The presence of dysphagia was evaluated using the American Speech-Language Hearing Association National Outcome Measurement System (ASHA NOMS) scale and variables that influenced swallowing rehabilitation in 140 adult patients who required invasive mechanical ventilation for >48 h. RESULTS: In total, 46.43% of the patients scored 1 or 2 on the ASHA NOMS (severe dysphagia) and 39.29% scored 4 (single consistency delivered orally) or 5 (exclusive oral diet with adaptations). Both the length of mechanical ventilation and the presence of neurological disorders were associated with lower ASHA NOMS scores (odds ratio [OR]: 0.80, 95% confidence interval [CI]: 0.74–0.87 P < 0.05; and OR: 0.13, 95% CI: 0.61–0.29; P < 0.05, respectively). Age and the presence of tracheostomy were negatively associated with speech rehabilitation (OR: 0.92; 95% CI: 0.87–−0.96; OR: 0.24; 95% CI: 0.80–−0.75), and acute post-COVID-19 kidney injury requiring dialysis and lower scores on the ASHA NOMS were associated with longer time for speech therapy outcomes (β: 1.62, 95% CI, 0.70–3.17, P < 0.001; β: −1.24, 95% CI: −1.55–−0.92; P < 0.001). CONCLUSION: Prolonged orotracheal intubation and post-COVID-19 neurological alterations increase the probability of dysphagia immediately after extubation. Increased age and tracheostomy limited rehabilitation.

RESUMO. O tratamento antirretroviral tem aumentado significativamente a sobrevida de pacientes contaminados pelo HIV-1. Entretanto, com o aumento da sobrevida, observam-se frequentemente alterações cognitivas associadas ao HIV nessa população. As manifestações clínicas das alterações do HIV podem variar em decorrência de diversos aspectos, entre eles a via de transmissão do vírus. Diversos estudos têm apontado alterações neurológicas prematuras em pacientes contaminados por via vertical, enquanto a manifestação de danos cognitivos em adultos pode levar um tempo maior. Objetivo: O objetivo deste estudo foi verificar a prevalência das alterações cognitivas em pacientes com HIV via transmissão vertical após a era da terapia antirretroviral altamente ativa e o desempenho cognitivo desses pacientes comparado ao de um grupo de pacientes contaminados por via sexual. Métodos: Foram avaliados 48 pacientes, sendo 25 com transmissão vertical e 23 com transmissão sexual no período entre maio de 2013 e fevereiro de 2015, no Instituto de Infectologia Emílio Ribas. Foram aplicados testes neuropsicológicos para avaliar o desempenho cognitivo, escalas para avaliar sintomas de ansiedade e depressão e questionário sociodemográfico. Resultados: Os resultados demonstraram que a frequência de comprometimento cognitivo em pacientes contaminados via transmissão vertical foi maior do que naqueles contaminados via transmissão sexual. Conclusões: Essas descobertas sugerem que os efeitos deletérios do vírus HIV na formação do sistema nervoso central repercutem de forma mais acentuada do que em pacientes que o adquiriram após a vida adulta.

ABSTRACT. Antiretroviral treatment has significantly increased the survival of patients infected with HIV-1. However, with increased survival, cognitive changes associated with HIV are frequently observed in this population. The clinical manifestations of HIV changes can vary as a result of several aspects, including the virus transmission route. Several studies have pointed out premature neurological changes in vertically infected patients, while the manifestation of cognitive damage in adults may take a longer time. Objective: The aim of this study was to verify the prevalence of cognitive changes in patients with HIV via vertical transmission after the highly active antiretroviral therapy and the cognitive performance of these patients compared to a group of sexually infected patients. Methods: A total of 48 patients were evaluated, 25 with vertical transmission and 23 with sexual transmission, between May 2013 and February 2015 at the Institute of infectology Emilio Ribas. Neuropsychological tests were applied to assess cognitive performance, scales to assess symptoms of anxiety and depression, and sociodemographic questionnaire. Results: The results demonstrate that the frequency of cognitive impairment in vertically transmitted patients was higher than in sexually transmitted patients. Conclusions: These findings suggest that the deleterious effects of the HIV virus on the development of the central nervous system reverberate more strongly than in patients who acquire it after adulthood.

RESUMO O DC de Neuroimunologia da ABN e o BCTRIMS trazem, nesse documento, as recomendações sobre vacinação da população com doenças desmielinizantes do sistema nervoso central (SNC) contra infecções em geral e contra o coronavírus da síndrome respiratória aguda grave 2 (SARS-CoV-2), causador da COVID-19. Destaca-se a gravidade do atual momento frente ao avanço da COVID-19 em nosso País, o que torna mais evidente e importante a criação de guia de referência para orientação aos médicos, pacientes e autoridades de saúde pública quanto à vacinação, meio efetivo e seguro no controle de determinadas doenças infecciosa. O DCNI/ABN e o BCTRIMS recomendam que os pacientes com doenças desmielinizantes do SNC (ex., EM e NMOSD) sejam constantemente monitorados, quanto a atualização do seu calendário vacinal, especialmente, no início ou antes da mudança do tratamento com uma droga modificadora de doença (DMD). É importante também salientar que as vacinas são seguras e os médicos devem estimular o seu uso em todos os pacientes. Evidentemente, deve ser dada especial atenção às vacinas com vírus vivos atenuados. Por fim, é importante que os médicos verifiquem qual DMD o paciente está em uso e quando foi feita a sua última dose, pois cada fármaco pode interagir de forma diferente com a indução da resposta imune.

ABSTRACT The Scientific Department of Neuroimmunology of the Brazilian Academy of Neurology (DCNI/ABN) and Brazilian Committee for Treatment and Research in Multiple Sclerosis and Neuroimmunological Diseases (BCTRIMS) provide recommendations in this document for vaccination of the population with demyelinating diseases of the central nervous system (CNS) against infections in general and against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes COVID-19. We emphasize the seriousness of the current situation in view of the spread of COVID-19 in our country. Therefore, reference guides on vaccination for clinicians, patients, and public health authorities are particularly important to prevent some infectious diseases. The DCNI/ABN and BCTRIMS recommend that patients with CNS demyelinating diseases (e.g., MS and NMOSD) be continually monitored for updates to their vaccination schedule, especially at the beginning or before a change in treatment with a disease modifying drug (DMD). It is also important to note that vaccines are safe, and physicians should encourage their use in all patients. Clearly, special care should be taken when live attenuated viruses are involved. Finally, it is important for physicians to verify which DMD the patient is receiving and when the last dose was taken, as each drug may affect the induction of immune response differently.

ABSTRACT The human T cell lymphotropic virus type 1 (HTLV-1) is the first human retrovirus discovered. Since then, it has spread worldwide and is mainly associated with adult T cell leukemia/lymphoma (ATLL) and HTLV1-associated myelopathy (HAM). Its relationship, however, with other types of cancer is controversial. We describe the case of a patient presenting with small cells lung epidermoid carcinoma who had recently developed HAM, and a review of the literature related to these conditions. This is the first case of this type of lung cancer, the same of the first description in the literature, associated with HAM outside Japan.

ABSTRACT Human immunodeficiency virus (HIV)-associated neurocognitive disorders are the main cause of cognitive decline and dementia in people living with HIV (PLHIV). However, extensive workup should be done in patients with rapidly progressive dementia (RPD) and HIV, especially when secondary infection in the central nervous system (CNS) is ruled out. Sporadic Creutzfeldt-Jakob disease (sCJD) is the main cause of RPD in non-HIV patients. It is a fatal neurodegenerative condition caused by prions that mainly affects elderly patients. Our objective is to describe two cases of PLHIV presenting with controlled infections and sCJD, and to review the literature. Our patients were younger than expected for sCJD and one of them had a longer disease course. As aging is expected to occur earlier in PLHIV, sCJD must be excluded in younger PLHIV presenting with RPD and without CNS infection.

RESUMO Introdução: A hepatite C pode ser definida como uma doença infecciosa, que se desenvolve por uma atividade inflamatória, que pode gerar um comprometimento no Sistema Nervoso Central, podendo ocasionar prejuízos cognitivos e sintomas de depressão. Objetivo: O objetivo deste estudo foi verificar o desempenho cognitivo de pacientes com hepatite C crônica antes e após o tratamento com simeprevir, sofosbuvir e daclatasvir. Métodos: Foi realizado um estudo prospectivo em três etapas: antes, logo após o tratamento e seis meses depois. Foram avaliados 58 pacientes em acompanhamento clínico no Instituto de Infectologia Emílio Ribas, em São Paulo, Brasil. Foram utilizados os seguintes instrumentos: questionário sociodemográfico, Escala de Lawton, Inventário de Depressão de Beck e uma bateria de testes neuropsicológicos que avaliaram: função intelectual, memória, atenção, função executiva e velocidade motora e de processamento). Para análise estatística, foram utilizadas as análises descritas (média, frequência e desvio padrão), qui-quadrado e ANOVA. Resultados: A maioria dos participantes era do sexo masculino (n=30, 51,7%), com média de 58,23±8,79 anos, escolaridade média de 9,75±4,43 anos. Comparando os resultados das avaliações neuropsicológicas (antes, logo após a finalização dos medicamentos e seis meses), observou-se melhora significativa em relação à aquisição de novos conhecimentos (p=0,03), memória visual tardia (p=0,01) e tendência em relação a atenção alternada (p=0,07). Conclusão: O tratamento do vírus da hepatite C melhorou o desempenho cognitivo, principalmente em relação à memória.

ABSTRACT Background: Hepatitis C can be defined as an infectious disease that develops an inflammatory activity, which may cause an impairment in the central nervous system, may cause cognitive impairments and symptoms of depression. Objective: The objective of this study was to verify the cognitive performance of patients with chronic hepatitis C before and after treatment with simeprevir, sofosbuvir, and daclatasvir. Methods: A prospective study was carried out in three stages: before, right after treatment, and six months after. Fifty-eight patients under clinical follow-up were evaluated at the Emílio Ribas Infectology Institute, in São Paulo, Brazil. The following instruments were used: sociodemographic questionnaire, Lawton’s Scale, Beck’s Depression Inventory, and a battery of neuropsychological tests that evaluated: intellectual function, memory, attention, executive function, and motor and processing speed). For statistical analysis, the analyses described (mean, frequency, and standard deviation), chi-square, and ANOVA were used. Results: Most of the participants were male (n=30, 51.7%), with a mean of 58.23±8.79 years, mean schooling of 9.75±4.43 years. Comparing the results of neuropsychological evaluations (before, just after completion of drugs, and six months), a significant improvement was observed in relation to the acquisition of new knowledge (p=0.03), late visual memory (p=0.01), and tendency towards alternate attention (p=0.07). Conclusion: The treatment of the hepatitis C virus improved cognitive performance, especially in relation to memory.

RESUMO Apesar da síndrome de HAM / TSP clássica ser a perturbação neurológica mais atribuída, alguns distúrbios neurológicos denominados “menores” são vistos em portadores “assintomáticos” de HTLV-1. Esses distúrbios, incluindo alterações cognitivas já observadas em descrições de casos clínicos e estudos, podendo constituir uma verdadeira síndrome clínica intermediária (SI) entre o estado assintomático e mielopatia. O objetivo deste estudo foi investigar a presença de déficits cognitivos em pacientes portadores do vírus HTLV-1 diagnosticados classicamente como assintomáticos. Métodos Foram avaliadas 54 pessoas, sendo 35 assintomáticos, 19 com alterações neurológicas menores (avaliados por um neurologista) e 25 HTLV-1 negativo. Os instrumentos utilizados foram: Inventário Beck de Depressão, Escala de Atividades de Vida Diária de Lawton e uma completa bateria neuropsicológica. A aplicação destes instrumentos de avaliação foi realizada de forma cega, ou seja, a avaliadora não sabia a condição clinica do paciente. Resultados A maioria dos participantes era do sexo feminino (n = 57, 72,21%), com idade média de 52.34 anos (DP = 14,29) e escolaridade média de 9.70 anos (DP = 4,11). Discussão Avaliando o desempenho cognitivo nos três grupos, foi possível observar que os participantes classificados com SI, apresentaram menores escores brutos, quando comparados, com os pacientes com classificação assintomática e grupo controle e, em relação à memória episódica auditiva de evocação imediata (p < 0,01) (p = 0,01) e tardia. Conclusão Diante dos resultados foi possível concluir que os pacientes com SI apresentam comprometimento de memória quando comparado com os outros grupos, sendo possível, ser este um dos sintomas para auxiliar na classificação da síndrome.

Background Although classical human T-cell lymphocyte virus type 1 (HTLV-1)-associated myelopathy/tropical spastic paraparesis syndrome is the most frequent HTLV-1-associated neurological disorder, some “minor” neurological disorders can be seen in “asymptomatic” carriers. These disorders, including cognitive alterations already described in clinical cases and studies, may constitute an intermediate syndrome (IMS) between the asymptomatic state and myelopathy. The aim of this study was to investigate the presence of cognitive deficits in patients with HTLV-1 virus, who usually are diagnosed as asymptomatic. Methods A total of 54 HTLV-1-infected patients were evaluated, 35 asymptomatic and 19 with minor neurological alterations (evaluated by a neurologist); 25 HTLV-1-seronegative individuals served as controls. The instruments used were: Beck’s Depression Inventory, Lawton’s Daily Life Activity Scale, and a complete neuropsychological battery. The application of these evaluation instruments was performed blindly, with the evaluator neuropsychologist not knowing the clinical condition of the patient. Results Most of the participants in this cohort, including seronegative controls, were female (n = 57, 72.21%), their mean age was 52.34 years (SD = 14.29) and their average schooling was 9.70 years (SD = 4.11). Discussion Participants classified with IMS had lower gross scores when compared with both the patients classified as asymptomatic and with the control group, and when tested for auditory episodic memory of immediate (p < 0.01), and late (p = 0.01), recall. Conclusion Patients with IMS presented with memory impairment when compared with asymptomatic patients and seronegative individuals; this is one of the symptoms that aids in the classification of the syndrome.

ABSTRACT This study evaluated the impact of urinary incontinence (UI) on sexuality, body image, mood, and quality of life of patients with myyelopathy associated with HTLV-1/tropical spastic paraparesis (HAM/TSP). The sample consisted of 31 HAM/TSP outpatients, of both sexes, followed-up at the Emílio Ribas Infectology Institute. The following instruments were used: sociodemographic questionnaire, Hospital Anxiety and Depression Scale (HAD), Body Image Assessment Scale, Sexual Quotient Female (QS-F) and Male (QS-M) Versions, King's Health Questionnaire (KHQ), and Revised OSAME Motor Disability Score. Data analysis was performed using descriptive statistics and the Mann-Whitney U-test was used for group comparison. The presence of UI was reported by 13 (41.9%) patients. Based on the quality of life questionnaire, patients with UI had a significant impact in the following domains: incontinence impact, daily life activities limitation, physical and social limitations, social relations, emotions, sleep and disposition, and severity measurements. Most participants had no anxiety (21; 67.7%) or depression symptoms (18; 58.1%). Regarding the sexual coefficient, 13 (41.9%) participants had sexual dissatisfaction. Conclusion: UI is common in HTLV-1 patients and may cause serious impairment in quality of life, with social, psychological and hygienic consequences. Nonetheless, there are few studies on this subject and their impact on mood and sexuality.

ABSTRACT Objective: We evaluated the association between cognitive deficits and leukocyte telomere length (LTL) in HIV-1-infected individuals. Design: 73 HIV-1-infected patients undergoing neuropsychological evaluation and 91 healthy controls were included in this study. Fifteen HIV-1 positive patients did not have cognitive disorders whereas 26 had asymptomatic neurocognitive disorder (ANI), 13 presented mild to moderate neurocognitive disorder (MND), and 10 had HIV-associated dementia (HAD). Methods: DNA from the peripheral blood of HIV-1-infected patients was used for measurement of telomere length by real-time PCR. HIV-1 viral load was determined in blood. Results: LTL decreased with age in healthy controls (p=0.0001). Regardless of the HIV status, age-matched LTL from HIV patients, including those with ANI and MND, were shortened in comparison to the healthy control group (p=0.0073); however, no association was found among the HIV-1-infected individuals with cognitive deficits (p=0.01). In addition, no gender-related association with LTL was observed (p=0.80), smoking, physical exercise, and plasma viral load were not correlated to telomere length (p=0.66). Conclusions: We concluded that leukocyte telomere length may not be a marker of cellular senescence in individuals with HIV infection and neurocognitive disorders.

RESUMO Introdução: o tratamento da infecção pelo vírus da imunodeficiência humana (HIV) tem diminuído a morbidade e a mortalidade por infecções oportunistas nesses pacientes e, portanto, aumentado a sobrevida. Essa nova realidade tem mudado o espectro de doenças que afetam esses pacientes. Objetivo: discutir a associação entre HIV e ocorrência de aneurismas cerebrais. Método: foi realizada revisão da literatura utilizando bancos de dados médicos. Foram pesquisados os seguintes descritores: "HIV e aneurismas intracranianos", "aneurismas intracranianos e síndrome da imunodeficiência adquirida", aneurismas, cérebro e HIV. Resultados: a relação entre a infecção pelo HIV e a formação de aneurismas parece ser real; porém, ainda faltam dados que confirmem a fisiopatologia dessa condição e seu melhor tratamento. Conclusão: existem novos sinais e sintomas, que devem ser estudados e pesquisados, relacionando o HIV com outras alterações previamente desconhecidas.

SUMMARY Introduction: the treatment of human immunodeficiency virus (HIV) infection has been decreasing patient morbidity and mortality by opportunistic infections and, thus, survival has increased. This new reality has been changing the spectrum of diseases affecting such patients. Objective: to discuss the association between HIV and the emergence of aneurysmal brain injuries. Method: it was performed a literature review using medical database. The following descriptors were searched: "Intracranial Aneurysms and HIV", "Intracranial Aneurysms and Acquired Immunodeficiency Syndrome," "aneurysm and brain and HIV". Results: after performed a literature review, it was observed that the relationship between HIV infection and the formation of aneurysms appears to be real, however, it still lacks data to confirm the pathophysiology of this condition and its best treatment. Conclusion: there are new signs and symptoms that should be studied and researched relating HIV with other changes not previously known.

ABSTRACT Um aumento expressivo da incidência de alterações cognitivas em pacientes com AIDS/HIV vem ocorrendo, assim três categorias de acometimento cognitivo foram propostas: comprometimento cognitivo assintomático (ANI) e alteração cognitiva leve/moderada (MND) que correspondem às formas leves e intermediárias; e demência associada ao HIV (HAD), a forma mais grave. O termo HIV-associated neurocognitive disorders (HAND) é uma denominação genérica que engloba as três categorias de acometimento. A aplicação de métodos de neuroimagem agregou grande avanço no entendimento das alterações neurológicas do HIV, promovendo maior confiabilidade na exclusão de patologias associadas e diagnóstico mais precoce. Diante disso, as alterações ou características específicas de neuroimagem podem ser em breve incorporadas aos critérios de classificação da HAND, o que será de grande valor no seu manejo, inclusive no auxílio para a otimização de esquemas antirretrovirais de alta penetração no SNC.

ABSTRACT A significant increase in the incidence of cognitive impairment in HIV/AIDS patients has been continuously observed. Consequently, three classification categories of cognitive impairment have been proposed: asymptomatic neurocognitive impairment (ANI) and mild neurocognitive disorder (MND), that correspond to the mild and intermediate forms, and HIV-associated dementia (HAD) for the most severe cases. HIV-associated neurocognitive disorders (HAND) is a broad term that encompasses these three categories. Moreover, the application of neuroimaging methods has led to a major breakthrough in understanding of the neurological changes in HIV, providing greater reliability in the exclusion of associated diseases and allowing earlier diagnosis. Therefore, abnormalities and/or specific neuroimaging elements may soon be incorporated into the HAND classification criteria, which will be of great value in the management of these diseases, including in the optimization of high CNS penetration antiretroviral regimens.

Natalizumabe é atualmente uma das melhores opções para o tratamento de pacientes com Esclerose Múltipla que não respondem aos tratamentos tradicionais. No entanto, o seu uso prolongado, o uso de terapia imunossupressora prévia e o status sorológico antivírus JC têm sido associados com o risco aumentado de desenvolvimento de Leucoencefalopatia Multifocal Progressiva (LEMP). A avaliação destas condições tem sido utilizada para estimar os riscos do desenvolvimento de LEMP nestes pacientes, e abordagens distintas (por vezes extremas) são empregadas para evitar o aparecimento dessa patologia. Atualmente, o grande desafio está em obter um equilíbrio entre os riscos e os benefícios do tratamento com Natalizumabe. Assim, é crucial desenvolver estratégias para monitorar pacientes portadores do vírus JC sob tratamento com Natalizumabe. A título de ilustração, pesquisamos o vírus no sangue e na urina de um paciente sob tratamento durante 12 meses. Também discutimos a eficácia dos métodos atualmente utilizados para avaliação de riscos e as implicações reais de reativação viral.

Natalizumab is currently one of the best options for treatment of patients with Multiple Sclerosis who have failed traditional prior therapies. However, prolonged use, prior immunosuppressive therapy and anti-JCV antibody status have been associated with increased risk of developing progressive multifocal leukoencephalopathy (PML). The evaluation of these conditions has been used to estimate risks of PML in these patients, and distinct (sometimes extreme) approaches are used to avoid the PML onset. At this time, the biggest issue facing the use of Natalizumab is how to get a balance between the risks and the benefits of the treatment. Hence, strategies for monitor JCV-positive patients undergoing Natalizumab treatment are deeply necessary. To illustrate it, we monitored JCV/DNA in blood and urine of a patient receiving Natalizumab for 12 months. We also bring to discussion the effectiveness of the current methods used for risk evaluation, and the real implications of viral reactivation.

A esclerose múltipla é a doença inflamatória auto-imune mais comum do sistema nervoso central. Sua etiologia já foi creditada apresentar tanto causas genéticas quanto ambientais. Vários vírus já foram implicados como desencadeadores desta doença e existem inúmeros trabalhos fazendo correlação entre a família Herpesviridae e a patogênese da esclerose múltipla. As características mais importantes dos Herpesviridae são as de apresentarem períodos de latência e exacerbação e terem como seu principal santuário biológico o sistema nervoso central. O vírus Epstein-Barr, o citomegalovírus, o herpesvirus tipo 6 e herpesvirus tipo 7 são os membros mais estudados como desencadeadores da esclerose múltipla. Conforme as evidencias que a literatura apresenta a família Herpesviridae está fortemente envolvida na patogênese da esclerose múltipla, porém é pouco provável que sejam os únicos responsáveis pelo seu início. É provável que esta doença apresente inúmeros desencadeadores e mais estudos são necessários para determinar estas interações.

Multiple sclerosis is the most common autoimmune inflammatory demyelinating disease of the central nervous system, and its etiology is believed to have both genetic and environmental components. Several viruses have already been implicated as triggers and there are several studies that implicate members of the Herpesviridae family in the pathogenesis of MS. The most important characteristic of these viruses is that they have periods of latency and exacerbations within their biological sanctuary, the central nervous system. The Epstein-Barr, cytomegalovirus, human herpesvirus 6 and human herpesvirus 7 viruses are the members that are most studied as being possible triggers of multiple sclerosis. According to evidence in the literature, the herpesvirus family is strongly involved in the pathogenesis of this disease, but it is unlikely that they are the only component responsible for its development. There are probably multiple triggers and more studies are necessary to investigate and define these interactions.

OBJETIVO: Avaliar a prevalência de excreção urinaria de vírus JC (VJC) e vírus BK (VBK) em pacientes HIV+ sem sintomas neurológicos. MÉTODOS: Amostras de urina de pacientes HIV+ sem sintomas neurológicos foram testados para a presença de VJC e VBK através da técnica de PCR. As amostras foram triadas para a presença de poliomavírus com par de primers complementares a região precoce do genoma do VBK e do VJC (AgT). A presença foi confirmada através de dois outros ensaios de PCR dirigidos a região do gene VP1 de ambos os vírus. A análise estatística foi realizada com auxílio do teste de Kruskal-Wallis para dados numéricos e Pearson ou Yater para variáveis categóricas. RESULTADOS: Ao todo foram inclusos no estudo 75 pacientes. A prevalência geral de excreção de poliomavírus na urina foi de 67/75 (89,3%). O DNA do vírus VBK foi detectado em 14/75 (18,7%) das amostras de urina, e o DNA do VJC foi detectado em 11/75 (14,7%) das amostras testadas. Ambos os vírus estavam presentes simultaneamente em 42/75 (56%) das amostras de urina. CONCLUSÃO: Encontramos, no presente estudo, uma alta taxa de excreção de VJC, VBK e excreção simultânea em pacientes HIV+. Ainda, esses resultados diferem de outros disponíveis na literatura.

OBJECTIVE: To evaluate the prevalence of the urinary excretion of BKV and JCV in HIV-infected patients without neurological symptoms. METHODS: Urine samples from HIV-infected patients without neurological symptoms were tested for JC virus and BK virus by PCR. Samples were screened for the presence of polyomavirus with sets of primers complementary to the early region of JCV and BKV genome (AgT). The presence of JC virus or BK virus were confirmed by two other PCR assays using sets of primers complementary to the VP1 gene of each virus. Analysis of the data was performed by the Kruskal-Wallis test for numerical data and Pearson or Yates for categorical variables. RESULTS: A total of 75 patients were included in the study. The overall prevalence of polyomavirus DNA urinary shedding was 67/75 (89.3%). Only BKV DNA was detected in 14/75 (18.7%) urine samples, and only JCV DNA was detected in 11/75 (14.7%) samples. Both BKV and JCV DNA were present in 42/75 (56.0%) samples. CONCLUSION: In this study we found high rates of excretion of JCV, BKV, and simultaneous excretion in HIV+ patients. Also these results differ from the others available on the literature.

The HAM/TSP caused by HTLV-1 infection usually affects patients to disabling states, and sometimes can lead them to paraplegia presenting symptoms of depression and anxiety, impacting on quality of life. Objective: The purpose of this study was to evaluate the frequency of depression and anxiety and its impact on quality of life in HTLV-1-infected TSP/HAM patients. Material and Methods: This was a cross-sectional study including 67 asymptomatic (control group) and 63 with TSP/HAM subjects. The instruments used were a demographic questionnaire, scales for anxiety and depression diagnosis (BDI and BAI), questionnaire for the assessment of Quality of Life of the World Health Organization (WHOQOL-Brief) and neurological scale to measure the disability level (Osame's Disability Status Scale). All patients had HTLV-I diagnosis by serological and molecular approaches, monitored at Instituto de Infectologia Emílio Ribas from May 2008 to July 2009. Data were analyzed statistically by frequencies, the Mann-Whitney test and the Spearman correlation test. Data among groups were analyzed and correlated with functional and severity aspects. Results: The results showed that patients with HAM/TSP compared to asymptomatic carriers had higher rates of depression (p < 0.001) and anxiety (p < 0.001), and impairment on quality of life in the areas of: dissatisfaction with health (p < 0.001), physical (p < 0.001) and the environment (p = 0.003). The main factors that correlated with levels of depression and anxiety and the domains of the WHOQOL-brief were: education, family income and social class. Conclusion: A well conducted evaluation and counseling may help in treatment, for a better quality of life of these patients.
