Abstract Chronic hepatitis B is an important health problem that can progress to cirrhosis and complications such as hepatocellular carcinoma. There is approximately 290 million of people with chronic hepatitis B virus (HBV) infection worldwide, however only 10% of patients are currently identified.Most part of Brazil is considered of low prevalence of HBV infection but there are some regions with higher frequency of carriers. Unfortunately, many infected patients are not yet identified nor evaluated for treatment.The Brazilian Society of Infectious Diseases (SBI) and the Brazilian Society of Hepatology worked together to elaborate a guideline for diagnosis and treatment of hepatitis B. The document includes information regarding the population to be tested, diagnostic tools, indications of treatment, therapeutic schemes and also how to handle HBV infection in specific situations (pregnancy, children, immunosuppression, etc).Delta infection is also part of the guideline, since it is an important infection in some parts of the country.

OBJETIVO: Traduzir para português brasileiro, adaptar culturalmente e avaliar as propriedades psicométricas (validade e confiabilidade) de um questionário de qualidade de vida (HIV/AIDS-Targeted Quality of Life Instrument, HAT-QoL) específico para pacientes infectados pelo HIV. MÉTODO: Estudo transversal realizado no ambulatório de infectologia da Escola Paulista de Medicina da Universidade Federal de São Paulo. Coletaram-se características sociodemográficas e clínicas de 106 indivíduos infectados pelo HIV, que responderam os questionários de qualidade de vida HAT-QoL e SF-36. O coeficiente de correlação de Pearson aferiu a validade de construto. Para avaliar a confiabilidade foram calculados o alfa de Cronbach e o coeficiente de correlação intraclasse. RESULTADOS: A proporção de homens na amostra foi de 70,8%. A média de idade foi 39,9 anos. Dos participantes, 40,5% eram homo ou bissexuais. Onze (10,4%) pacientes tinham contagem de células CD4 < 200 células/mm3. Entre os nove domínios do HAT-QoL, sete (função geral, satisfação com a vida, preocupações com a saúde, preocupações com a medicação, aceitação do HIV, confiança no profissional e função sexual) apresentaram efeito teto substancial. O domínio "função sexual" foi o que apresentou efeito teto mais alto (63,2%). O domínio preocupações financeiras apresentou efeito chão substancial (30,2%). Associações estatisticamente significativas foram observadas entre os domínios do HAT-QoL e características sociodemográficas e clínicas e domínios do questionário SF-36. A consistência interna foi satisfatória (alfa de Cronbach = 0,73 a 0,90). A reprodutibilidade inter e intraobservador foi muito alta (0,87 a 0,98 e 0,82 a 0,97, respectivamente). CONCLUSÃO: O HAT-QoL em português brasileiro é um instrumento válido, confiável e que pode contribuir para avaliar o impacto da infecção pelo HIV sobre a qualidade de vida de pacientes brasileiros.

OBJECTIVES: To translate the HIV/AIDS-Targeted Quality of Life Instrument (HAT-QoL) into Brazilian Portuguese, culturally adapt it, and evaluate its psychometric properties (validity and reliability) as a Brazilian version. METHODS: This cross-sectional study was carried out at the laboratory of infectious diseases at Escola Paulista de Medicina (Universidade Federal de São Paulo). Data were collected on clinical and sociodemographic characteristics of 106 HIV-infected individuals who answered the HAT-QoL and the SF-36®. Pearson's correlation coefficient was used to measure construct validity. Reliability was assessed using Cronbach's alpha and intraclass correlation coefficients. RESULTS: The sample was 70.8% male. The mean age was 39.9 years, with 40.5% of the participants being homosexual or bisexual. Eleven (10.4%) patients had a CD4 cell count < 200 cells/mm3. A substantial ceiling effect was observed in 7 of 9 HAT-QoL domains (overall function, life satisfaction, health worries, medication worries, HIV acceptance, provider trust, and sexual function). Sexual function was the domain with the highest ceiling effect (63.2%). A substantial floor effect (30.2%) was observed for financial worries. Statistically significant associations were observed between the HAT-QoL domains and clinical and sociodemographic characteristics, as well as with SF-36 domains. Internal consistency was satisfactory (Cronbach's alpha = 0.730.90). Inter- and intra-observer reproducibility was very high (0.870.98 and 0.820.97, - respectively). CONCLUSION: The Brazilian Portuguese version of the HAT-QoL is valid, reliable, and may contribute to evaluating the impact of HIV infection on the quality of life of patients in Brazil.
