Quality of life, risk behaviors and depression among carriers of hepatitis C virus and human T-cell lymphotropic virus type 1: a comparative study

Abstract Human T-cell lymphotropic virus type 1 (HTLV-1) has low prevalence rates, but is endemic in some regions of the world. It is usually a chronic asymptomatic infection, but it can be associated with serious neurologic and urinary conditions. Hepatitis C virus (HCV) is broadly spread out worldwide. The majority of these infections have a chronic course that may progress to cirrhosis and hepatocellular carcinoma. Objectives: To compare sociodemographic and mental health (risk behaviors, depression, and suicide) aspects, and quality of life among patients with HCV or HTLV-1. Methods: Observational, comparative and cross-sectional study involving outpatients with HCV or HLTV-1 infection. Sociodemographic characteristics, risk behaviors and quality of life were assessed through the questionnaires Mini International Neuropsychiatric Interview - MINI Plus (depression and suicide) and Medical Outcomes Study 36-Item Short-Form Health Survey (quality of life). Univariate and multivariate statistical analyses (hierarchical logistic regression) were conducted. Results: 143 individuals with HCV and 113 individuals with HTLV-1 infection were included. Males were predominant in the HCV group (68.8%) and females in the HTLV-1 group (71.7%). The frequency of risk behaviors (sexual and drug use) was greater in those with HCV (p < 0.05). A past depressive episode was more common in the HTLV-1 group (p = 0.037). Quality of life was significantly worse in the physical functioning, vitality, mental health, and social functioning domains in those with HTLV-1 (p < 0.05). HTLV-1 infection remained independently associated with worse quality of life in multivariate analysis. Conclusions: Risk behaviors are frequent among those infected with HCV. Additionally, despite HTLV-1 being considered an infection with low morbidity, issues related to mental health (depressive episode) and decreased quality of life are relevant.

Memory impairment: an intermediate clinical syndrome symptom in HTLV-1-infected patients? / Comprometimento da memória: um sintoma de síndrome clínica intermediária em pacientes infectados pelo HTLV-1?

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.

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.

Depression and anxiety disorders among patients with human T-cell lymphotropic virus type-1: a cross-sectional study with a comparison group

Abstract INTRODUCTION: Studies have linked human T-cell lymphotropic virus type-1 (HTLV-1) to psychiatric disease. METHODS: Patients with HTLV-1 were compared to patients seen by family doctors using a semi-structured questionnaire and the Hospital Anxiety and Depression Scale. RESULTS: Participants with (n=58) and without (n=340) HTLV were compared. Anxiety and depression were associated with greater age, being a woman, spastic paraparesis (depression: PR=4.50, 95% CI: 3.10-6.53; anxiety: PR=2.96, 95% CI: 2.08-4.21), and asymptomatic HTLV (depression: PR=4.34, 95% CI: 3.02-6.24; anxiety: PR=2.81, 95% CI: 2.06-3.85). CONCLUSIONS: Symptomatic and asymptomatic patients with HTLV-1 experienced more anxiety and depression than uninfected patients.

Suicide risk and alcohol and drug abuse in outpatients with HIV infection and Chagas disease

Objective: To evaluate psychiatric comorbidities in outpatients receiving care for HIV and Chagas disease at Instituto de Pesquisa Clínica Evandro Chagas (IPEC), Fundação Oswaldo Cruz (Fiocruz), Rio de Janeiro, Brazil. Methods: Cross-sectional study with a consecutive sample of 125 patients referred to an outpatient psychiatric clinic from February to December 2010. The Mini International Neuropsychiatric Interview (MINI) was used. Factors associated with more frequent mental disorders were estimated by odds ratios (OR) with 95% confidence intervals (95%CI) by multiple logistic regression. Results: Seventy-six (60.8%) patients with HIV, 40 (32%) patients with Chagas disease, and nine (7.2%) patients with human T-lymphotropic virus were interviewed. The majority were women (64%), with up to 8 years of formal education (56%), and unemployed (81.6%). The median age was 49 years. Suicide risk (n=71) (56%), agoraphobia (n=65) (52%), major depressive episode (n=56) (44.8%), and alcohol/drug abuse (n=43) (34.4%) predominated, the latter being directly associated with lower family income (OR = 2.64; 95%CI 1.03-6.75) and HIV infection (OR = 5.24; 95%CI 1.56-17.61). Suicide risk was associated with non-white skin color (OR = 2.21; 95%CI 1.03-4.75), unemployment (OR = 2.72; 95%CI 1.01-7.34), and diagnosis of major depression (OR = 3.34; 95%CI 1.54-7.44). Conclusion: Measures targeting adverse socioeconomic conditions and psychiatric and psychological monitoring and care should be encouraged in this population, considering the association with abuse of alcohol/other psychoactive drugs and suicide risk. .

Frequency of mental disturbances in HTLV-1 patients in the state of Bahia, Brazil

Viral infections and chronic diseases have been associated with psychiatric disorders. Among these, increased depression has been reported in HTLV-1 patients. However, no studies on the prevalence of other mental disturbances have been carried out in these patients. Salvador is the city with the highest rate of infection with HTLV-1 in Brazil and it is estimated that approximately 40,000 inhabitants are infected. In our cross sectional study, we examined the frequency of mental disturbances in 50 HTLV-1 seropositive patients followed at the Centro Integrativo e Multidisciplinar de HTLV e Hepatites Virais (CHTLV) of the Escola Bahiana de Medicina e Saude Pública (EBMSP) in Salvador from January to November 2007. We used a questionnaire to collect clinical-epidemiologic data and the Mini International Neuropsychiatric Interview Brazilian Version 5.0.0 (M.I.N.I.) to evaluate the psychiatric disorders. The Statistical Package for Social Sciences (SPSS) was used for the analyses. Twenty-one (42 percent) HTLV-1 patients had a psychiatric co-morbidity; 17(34 percent) had mood disorders, 11 (22 percent) were anxious and one (2 percent) was an alcoholic. We found a high frequency of mental disturbances among HTLV-1 infected individuals, suggesting a possible association of this infection with psychiatric diseases.

Aspectos psicológicos, observados em doadores, relacionados à comunicaçäo da infecçäo pelo HTLV-1 / Psychological aspects in donors related to communication of HTLV-1 infection

A comunicaçäo de diagnóstico muitas vezes pode provocar reaçöes de medo, insegurança, ansiedade e tensäo, até outras reaçöes imprevisíveis. Um aspecto importante a ser considerado é a maneira como se faz essa comunicaçäo, podendo isso suscitar fantasias errôneas e demasiado apressadas como o verificado da associaçäo do HTLV-1 com o HIV. Assim este trabalho compreende duas partes: Na primeira, descreve-se as reaçöes de ansiedade decorrentes da informaçäo, bem como a ansiedade apresentada como traço de personalidade do indivíduo. Na segunda parte, apresentamos outros aspectos que de modo geral podem interferir na qualidade de vida e no comportamento dessas pessoas.
