Comparative study of impulsiveness and risk behaviors among infected individuals with hepatitis C virus and human T-cell lymphotropic virus type 1.

INTRODUCTION AND OBJECTIVES: Hepatitis C virus (HCV) and human T-cell lymphotropic virus type 1 (HTLV-1) infections have chronic courses. HCV is primarily transmitted via the hematogenous route, whereas HTLV-1 is primarily transmitted sexually, although it can also be transmitted by blood. Individuals chronically infected with either HTLV-1 or HCV can differ in terms of behavioral characteristics and personality traits. This study compared the occurrence of risk behaviors and impulsivity aspects between HCV and HTLV-1 carriers. MATERIALS AND METHODS: Observational, comparative and cross-sectional study that involved a sample of outpatients who had HCV or HLTV-1, by way of a sociodemographic and behavioral questionnaire and the Barratt Impulsiveness Scale - BIS-11. 143 individuals with HCV and 113 individuals with HTLV-1 were evaluated. RESULTS: There was a difference with regards to gender among patients, with mostly males affected in the HCV group. Risk behaviors commonly mediated by impulsiveness were significantly more frequent in the HCV group. Similarly, overall impulsiveness and domain nonplanning were higher in the HCV group. Multivariate analysis showed that increased age, male gender, higher nonplanning scores and HCV infection were independent factors for the occurrence of risk behaviors. Both groups presented high rates of other sexually transmitted diseases and a low rate of condom use in sexual relations. CONCLUSIONS: This study confirms the higher rate of risk behaviors and the levels of impulsiveness commonly observed in patients with HCV, along with comparisons to patients with HTLV-1.

The Portuguese Version of the Immunosuppressant Therapy Adherence Scale (ITAS) among Liver Transplant Recipient Patients: Translation and Psychometric Properties.

INTRODUCTION AND AIM: Transplant recipients are chronically ill patients who rely on medical treatment throughout life to achieve positive results. Despite that, medication nonadherence after liver transplantation is extremely common. The self-report, one of several methods for measuring adherence, is easy to apply and low cost. Thus, this study aims to translate and validate the Immunosuppressant Therapy Adherence Instrument (ITAS) in Brazilian Portuguese for liver transplant recipients. MATERIAL AND METHODS: A total of 139 liver transplant recipients were selected from a general hospital, who were assessed by using the Portuguese version of ITAS. The scale was translated based on the model proposed by Wild, et al. and its psychometric properties were assessed. RESULTS: The average Cronbach's α coefficient was 0.830. ITAS and Basel Assessment of Adherence with Immunosuppressive Medications Scale (BAASIS) presented significant correlation, with a Spearman's ρ coefficient = 0.300 (S = 309,580; p < 0.001). The area under the receiver operating characteristics (ROC) curve was 0.638 (95% CI: 0.557 - 0.715). Factor analysis results indicated that the carelessness factor model was the optimal model, and the factor "feeling worse" was the lowest. CONCLUSION: The Portuguese version of ITAS has adequate psychometric properties to measure adherence to immunosuppressant therapy.

The fatigue impact scale for daily use in patients with hepatitis B virus and hepatitis C virus chronic infections.

INTRODUCTION: Fatigue is an important clinical finding in the hepatitis virus chronic infection. However, the absence of scales to measure fatigue, translated and validated for Brazilian Portuguese, prevents access to information essential in clarifying specific clinical conditions in this population. AIM: The aim of this study was to determine the psychometric properties of the fatigue impact scale for daily use (D-FIS), in Brazilian Portuguese, for patients with the hepatitis C virus (HCV) and hepatitis B virus (HBV) chronic infection. MATERIAL AND METHODS: In this cross-sectional study, the authors evaluated the D-FIS in 101 outpatients, followed at the reference hospital. The Mini International Neuropsychiatric Interview Brazilian (MINI PLUS) was used to identify psychiatric disorders, and the Short Form Health Survey 36-item (SF-36) to evaluate the self-reported quality of life. We also examined the impact of fatigue on the quality of life of this group of patients. RESULTS: Relevant psychometric D-FIS results were: floor effect proved to be 1%; skewness was 0.46; item homogeneity was 0.59 and SEM (SD = 8.51) was 2.4. The Cronbach's alpha was 0.920 and item total correlation yielded coefficients ranging from 0.65 (item 1) to 0.85 (item 3). In a linear regression model, fatigue and depression influenced the self-reported quality of life. CONCLUSION: This study presents that the fatigue scale for daily use in Brazilian Portuguese can be considered a useful tool to verify the presence of fatigue in patients with the hepatitis viruses B and C.

Impact of sustained virologic response on quality of life in chronic HVC carriers.

INTRODUCTION: It is known that patients with chronic hepatitis C have a lower health-related quality of life (HRQOL) than the general population and evidence suggests that the hepatitis C virus (HCV) could exert direct neuropathic action on HRQOL. From this perspective, the virus clearance should be accompanied by improvement in HRQOL. Thus, we sought to review systematically the evidence in the literature and perform a meta-analysis of HRQOL changes caused by sustained virologic response (SVR). MATERIAL AND METHODS: The PubMed was searched using the keywords Hepatitis C, Quality of Life and Therapy. The reviewers came to a consensus on articles that were selected to full reading and those that should be included in the study and a meta-analysis was performed of mean change difference between responders and non-responders. RESULTS: Eleven studies were included in the systematic review and four in the metaanalysis. Of these, nine studies showed more favorable outcome for responders, and they had a better outcome even in studies that evaluated only cirrhotic patients, previous non-responders, relapsers, patients in first treatment and patients unaware of treatment response. Moreover, the meta-analysis showed that the general health and vitality domains had statistically significant mean change difference between responders and non-responders, presenting a summary effect of 6.3 (CI 95% 2.5-10.0) and 7.8 (CI 95% 3.4- 12.1) respectively. CONCLUSION: There is evidence indicating that SVR is accompanied by an improvement in HRQOL and patients reaching SVR have clinically relevant improvement in domains of general health and vitality.

MENTAL DISORDERS AND LIVER TRANSPLANTATION: A 2-YEAR COHORT STUDY.

BACKGROUND: Psychosocial assessment is a key component in evaluation for liver transplantation and may affect survival rates and outcomes. OBJECTIVE: The primary aim of this study was to investigate the impact of previous mental disorders and impulsivity on the 2-year surviving rate after liver transplantation. METHODS: We performed a prospective cohort study assessing end-stage liver disease individuals with and without psychiatric comorbidities for 2 years post-transplant. Psychiatric diagnosis was carried out through Mini-Plus 5.0.0 and impulsivity by using Barratt Impulsiveness Scale in the pre-transplant phase. We followed patient's status for 2 years after transplantation. The main outcome was death. We used a logistic regression to evaluate the association of psychiatric comorbidities with death and performed a survival analysis with Kaplan-Meier and Cox regression models. RESULTS: Between June 2010 and July 2014, 93 out of 191 transplant candidates received transplants. From the 93 transplant patients, 21 had psychiatric comorbidities and 72 had not. 25 patients died during the study. The presence of psychiatric comorbidities (P=0.353) and high impulsivity (P=0.272) were not associated to 2-year post transplant death. CONCLUSION: This study found no evidence that the presence of mental disorders and impulsivity worsened prognosis in post-liver transplantation.

Psychometric properties the of Brazilian Portuguese version of Snaith-Hamilton Pleasure Scale (SHAPS).

INTRODUCTION: Anhedonia is defined as the reduced ability to feel pleasure and is a core symptom of various psychiatric disorders such as depression and schizophrenia. The Snaith-Hamilton Pleasure Scale (SHAPS) was developed to assess the presence of anhedonia. The objective of this study was to assess the psychometric properties of the Brazilian Portuguese version of the SHAPS. METHODS: In this study, the SHAPS (14 items) was translated into Brazilian Portuguese and validated using data obtained from 228 subjects within a clinical sample. Psychometric properties were assessed using item response theory (logistic models) and classical test theory (Cronbach's alpha). We checked for external validity using a non-parametric correlation with an independent scale: Hospital Anxiety and Depression Scale - Depression subscale (HAD-D). RESULTS: The SHAPS presented good internal consistency, with a Cronbach's α coefficient of 0.759 and adequacy to an IRT 1 parameter logistic (Rasch) model. The SHAPS presented significant correlation with the external measure HAD-D, with Spearman's ρ = 0.249 (S = 1368914; p < 0.001). CONCLUSION: These results suggest that the Brazilian Portuguese version of the SHAPS is a reliable and valid instrument to assess hedonic tone.

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

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.

MENTAL DISORDERS AND QUALITY OF LIFE IN PATIENTS AWAITING LIVER TRANSPLANTATION.

BACKGROUND: Liver transplantation is the main therapeutic alternative for patients with advanced liver disease. These patients have high prevalence of psychiatric comorbidities that may negatively interfere in clinical outcomes and quality of life. It is not clear in the literature whether the different etiologies of hepatic disease have the same prevalence of psychiatric disorders. OBJECTIVE: The aim of this study was to investigate whether patients in the liver transplant list showed differences in psychiatric characteristics, medical variables and quality of life among different etiological groups. METHODS: This is a cross-sectional study that evaluates quality of life, psychiatric and clinical comorbidities through the application of validated questionnaires and instruments in 248 patients who were on transplant waiting list from 2010 to 2014, assisted in a University Hospital and in a Private Hospital in Salvador/Bahia, Brazil. The patients were evaluated through the Mini International Neuropsychiatric Interview (M.I.N.I. PLUS 5.0) and Medical Outcomes Short-Form Health Survey (SF-36). RESULTS: The etiology of the most prevalent liver disease was hepatitis C virus. A prevalence of 50.8% of at least one mental disorder was identified. When alcohol abuse/dependence was excluded, the prevalence was 25.8%. Mental health did not show a statistically significant difference in the diverse etiological groups, but a higher prevalence of psychiatric comorbidities was detected among women and younger than 40 years. No cases of psychotic disorders were detected, possibly by exclusion prior to listing. There was no difference in the quality of life domains in the different liver etiological groups. CONCLUSION: A high-prevalence of psychiatric disorders was found among all clinical conditions most associated with indication for liver transplantation. Attention is drawn to the absence of patients with psychotic disorders, which suggests that transplantation may not have been indicated for this group of patients. For these reasons, professionals caring for liver transplant candidates should be highly vigilant for the presence of mental disorders, regardless of the etiology of liver disease. Specialized care is recommended to minimize the early exclusion of patients with no other therapeutic possibilities, as well as care of all people with mental disorders.

Transtorno mental e transplante hepático: um estudo de coorte de 2 anos / Mental disorders and liver transplantation: a 2-year cohort study

RESUMO Contexto: A avaliação psicossocial é essencial na avaliação para transplante hepático; ela pode afetar as taxas de sobrevida e outros desfechos. Objetivo: O objetivo principal deste estudo foi investigar o impacto de transtornos mentais prévios e impulsividade nos índices de sobrevivência após o transplante hepático. Métodos: Foi realizado um estudo prospectivo de coorte com indivíduos em estágio avançado da doença hepática com e sem comorbidades psiquiátricas no pré-transplante, acompanhados por 2 anos após o transplante. Na fase pré-transplante foi realizado o diagnóstico psiquiátrico através do Mini-Plus 5.0.0 e avaliada a impulsividade através da Escala de Impulsividade Barratt. Os pacientes foram acompanhados por 2 anos após o transplante. O desfecho principal foi óbito. Foi utilizada regressão logística para avaliar a associação entre comorbidades psiquiátricas e óbito. Também foi realizada análise de sobrevida com Kaplan-Meier e modelo de regressão Cox. Resultados: Entre junho de 2010 e julho de 2014 foram transplantados 93 pacientes entre os 191 candidatos. Dos 93 pacientes transplantados, 21 tinham comorbidade psiquiátrica e 72 não tinham. Durante o período de acompanhamento houve 25 óbitos. A presença de comorbidade psiquiátrica (P=0.353) e alta impulsividade (P=0.272) não foram associadas a óbito pós-transplante até segundo ano de cirurgia. Conclusão: Este estudo não encontrou evidências de que a presença de transtorno mental e impulsividade pioram o prognóstico pós-transplante hepático.

Risk-taking behavior and impulsivity among HCV-infected patients.

The association between risk behaviors and hepatitis C virus (HCV) has been extensively studied. It is also proved that impulsivity is associated with risk behaviors. However, there is a lack of studies investigating the association between HCV and impulsivity, a characteristic that can contribute directly to these risk behaviors. This study aimed to investigate HCV-infected individuals' impulsivity and whether this feature mediates risk behavior. Adult patients with liver diseases (n=269) were divided into two groups: viral group (n=157) - patients with HCV and nonviral group (n=112). Risk behaviors were evaluated by a sociodemographic questionnaire. Impulsivity was assessed through Barratt Impulsiveness Scale - BIS-11. Psychiatric comorbidities were investigated by the Mini International Neuropsychiatric Interview 5.0.0. The viral group patients had higher impulsivity than the nonviral group in all domains: attentional impulsivity, motor impulsivity, and nonplanning. Risk behaviors were also shown to be associated with impulsivity levels. Our results suggest that HCV-infected patients are more impulsive than individuals with other liver diseases, even when analyses are controlled for the presence of comorbid mental disorders. In addition, at-risk behavior was significantly mediated by impulsivity.

Desordens mentais e qualidade de vida em pacientes em lista de espera para realização de transplante de fígado / Mental disorders and quality of life in patients awaiting liver transplantation

RESUMO CONTEXTO: O transplante hepático é a principal alternativa terapêutica para pacientes com doença hepática avançada. Esses pacientes apresentam alta prevalência de comorbidades psiquiátricas que podem interferir negativamente nos desfechos clínicos e qualidade de vida. Não está claro na literatura se as diferentes etiologias de doença hepática têm a mesma prevalência de transtornos psiquiátricos. OBJETIVO: O objetivo deste estudo foi investigar se os pacientes na lista de transplante hepático apresentavam diferenças nas variáveis psiquiátricas, variáveis clínicas e qualidade de vida em diferentes grupos etiológicos. MÉTODOS: Estudo transversal que avalia as comorbidades psiquiátricas e clínicas e as variáveis de qualidade de vida por meio da aplicação de questionários e instrumentos validados em 248 pacientes inseridos em lista de espera para transplante hepático no período de 2010 a 2014, acompanhados no Hospital Universitário Professor Edgard Santos e Hospital Português (Salvador, BA). Os pacientes foram avaliados através da aplicação do Mini International Neuropsychiatric Interview (M.I.N.I. PLUS 5.0) e Medical Outcomes Short-Form Health Survey (SF-36). RESULTADOS: A etiologia da doença hepática mais prevalente foi o vírus da hepatite C. Prevalência de 50,8% de pelo menos um transtorno mental foi identificada. Quando o abuso/dependência de álcool foi excluído, a prevalência foi de 25,8%. A saúde mental não apresentou diferença estatisticamente significante nos diversos grupos etiológicos. Maior prevalência de comorbidades psiquiátricas foi detectada entre mulheres e menores de 40 anos. Não foram detectados casos de transtornos psicóticos, possivelmente pela não inclusão destes pacientes na lista. Não houve diferença nos domínios de qualidade de vida nos diferentes grupos etiológicos. CONCLUSÃO: Uma alta prevalência de transtornos psiquiátricos foi encontrada nos pacientes com todas as condições clínicas mais associadas à indicação de transplante hepático. Chama a atenção a ausência de pacientes com transtornos psicóticos, o que sugere que possivelmente o transplante não tem sido indicado para esse grupo de pacientes. Por esses motivos, os profissionais que cuidam de candidatos ao transplante de fígado devem ser altamente vigilantes para a presença de transtornos mentais, independentemente da etiologia da doença hepática. A atenção especializada é recomendada para os pacientes com transtornos mentais, com minimização de exclusão precoce da lista de pacientes sem outras possibilidades terapêuticas.

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.

Hepatitis C virus infection as a traumatic experience.

OBJECTIVE: The purpose of this study was to evaluate whether individuals consider their HCV infection to be a potentially traumatic experience. Additionally, we investigated its association with Post-Traumatic Stress Disorder (PTSD) and the impact of PTSD diagnosis on health-related quality of life (HRQoL) in HCV infected subjects. METHODS: We conducted a cross-sectional survey of 127 HCV-infected outpatients recruited at a University Hospital in Salvador, Brazil. All subjects answered an orally-administered questionnaire to gather clinical and socio-demographic data. We investigated traumatic experiences and the subject's perception of the disease using the Trauma History Questionnaire. PTSD and other psychiatric diagnoses were assessed through the Mini International Neuropsychiatric Interview-Brazilian Version 5.0.0 (M.I.N.I. PLUS). HRQoL was assessed using Short-Form 36 (SF-36). RESULTS: Approximately 38.6% of the patients considered hepatitis C to be a traumatic experience. Of these, 60.7% had a PTSD diagnosis. PTSD was associated with significant impairment in quality of life for individuals in seven SF-36 domains as shown bymultivariate analysis: Role-Physical (ß: -24.85; 95% CI: -42.08; -7.61), Bodily Pain (ß: -19.36; 95% CI: -31.28; -7.45), General Health (ß: -20.79; 95% CI: -29.65; -11.92), Vitality (ß: -11.92; 95% CI: -20.74; -3.1), Social Functioning (ß: -34.73; 95% CI: -46.79; -22.68), Role-Emotional (ß: -26.07; 95% CI: -44.61; -7.53), Mental Health (ß: -17.46; 95% CI: -24.38; -10.54). CONCLUSION: HCV is frequently a traumatic experience and it is strongly associated with PTSD diagnosis. PTSD significantly impaired HRQoL.

Post-traumatic stress disorder as a comorbidity: impact on disease outcomes.

Post-traumatic stress disorder (PTSD) is associated with many psychiatric and nonpsychiatric comorbidities. Growing evidence suggests that PTSD as a comorbidity may impair drug adherence, quality of life and sleep quality, as well as increase rehospitalization rates, disease relapses, intensity of symptoms, morbidity and mortality. The aim of this article is to examine the literature regarding the effects of PTSD comorbidity on physical and mental health.
