RESUMEN
OBJECTIVE: To compare physical activity levels and dietary choices of patients who have chronic hepatitis C (CHC) with those of blood donors (BDs). DESIGN: A prospective survey. SETTING: A liver disease treatment center and a blood donor center from a nonprofit health system. PATIENTS: A total of 149 subjects (93 with CHC and 56 BDs) participated. Subjects were 18 years or older and agreed to participate; those with CHC had no evidence of cirrhosis. METHODS: All subjects provided basic clinical information and completed a nutrition survey, which contained questions about dietary choices and their frequency, and the Human Activity Profile, which measured maximum effort (Maximum Activity Score; MAS) and daily activity (Adjusted Activity Score; AAS). MAIN OUTCOMES MEASUREMENTS: MAS and AAS scales and 13 indices on the nutrition survey. Independent samples t-tests, Pearson correlations, and multiple stepwise regression analyses were performed. RESULTS: No significant differences were found between BDs and patients with CHC in terms of age, gender, race, body mass index, hyperlipidemia, hypertension, or diabetes mellitus. Mean body mass index was 27.5, 17.8% had hyperlipidemia, and 9.6% had diabetes. BDs reported significantly more exercise per week (mean: patients with CHC = 193.6 minutes/week and BDs = 280.4 minutes/week; P = .039) and had a significantly greater MAS (mean: patients with CHC = 77.2 and BDs = 87.4, P = .0001) and AAS (mean: patients with CHC = 72.58 and BDs = 83.8, P = .0001). Stepwise multiple regression analysis proposed 2 models predicting AAS: the presence of CHC (R = .445; R(2) = .198; adjusted R(2) = .184); and the presence of CHC and presence of hypertension (R = .537; R(2) = .289; adjusted R(2) = .263). BDs consumed significantly more alcohol and starchy foods than did patients with CHC (P = .0001 and P = .031, respectively), which may be explained by the compliance of patients with CHC to their hepatologist's recommendations regarding the minimization of alcohol consumption. CONCLUSIONS: Persons with CHC participate in less activity and less vigorous physical activity than do BDs and consume less starch and alcohol. These data about activity level and dietary intake in patients with CHC are novel; few data on these topics have been published previously. Low level of activity adds a substantial risk to this overweight CHC population, many of whom have multiple components of metabolic syndrome.

BACKGROUND: Obesity is not only associated with nonalcoholic fatty liver disease (NAFLD) but it also adversely affects the progression of other liver diseases. There are limited data regarding the dietary habits of patients with chronic liver disease. METHODS: Nutrition surveys containing 13 different food groups were mailed. Nutrition scores were calculated based on weekly servings. Foods were also divided into USDA food pyramid categories with conversion of each group into calories expended. Clinico-demographic data were available. NAFLD patients were compared to patients with chronic viral hepatitis. RESULTS: A total of 233 subjects were included: age 52.5 +/- 10.0 years, Body mass index (BMI) 28.1 +/- 6.5, MS 24.2%, 31.8% NAFLD, 48.1% hepatitis C virus (HCV), and 20.2% hepatitis B virus (HBV). Six nutrition indices were different among the groups. NAFLD and HCV consumed more low-nutrient food (p = 0.0037 and 0.0011) and more high-sodium food than HBV (p = 0.0052 and 0.0161). Multivariate analysis showed that NAFLD and HCV consumed more high-fat sources of meat/protein than HBV (p = 0.0887 and 0.0626). NAFLD patients consumed less calories from fruits compared to HCV and HBV patients (p = 0.0273 and 0.0023). Nine nutrition indices differed according to BMI. Univariate analysis showed that obese/overweight patients consumed more high-fat sources of meat/protein (p = 0.0078 and 0.0149) and more high-sodium foods (p = 0.0089 and 0.0062) compared to the normal-weight patients. In multivariate analysis, normal-weight patients consumed more fruits than obese (p = 0.0307). Overweight patients also consumed more calories of meat and oil than normal-weight patients (p = 0.0185 and 0.0287). CONCLUSION: NAFLD and HCV patients have similar dietary habits. Patients with HBV have the healthiest dietary habits. Specific dietary interventions should focus on decreasing intake of low-nutrient and high-sodium food, as well as high-fat sources of meat/protein.

Assessment of health-related quality of life (HRQL) and health utilities have become important aspects of clinical research. Patient-derived utility adjustments are frequently used in economic analysis. Although HRQL has been frequently studied among patients with liver disease, extensive data on the health utilities of patients with liver disease are not available. Recently, SF-6D has been developed to obtain utility scores from the widely used Short Form 36 questionnaire. To assess health utilities of patients with chronic liver disease using 2 utility assessments [SF-6D and Health Utility Index 2 (HUI-2)], a total of 140 patients were identified from our Liver Disease Quality of Life Database with HRQL data available, as well as clinical and demographic data. Of the 140 patients, 42% were female, had a mean age of 49.4 years (standard deviation = +/-11.2) 36% had hepatitis B virus (HBV), 29% had hepatitis C (HCV), 24% had cholestatic liver disease, and 11% had another liver disease (for example, nonalcoholic steatohepatitis). Bivariate analyses indicated that HBV patients had the highest health status as measured by all of SF-6D and HUI-2 subscales and the overall SF-6D and HUI-2 utility measures, whereas patients with HCV and cholestatic liver disease had similar scores, and those with other liver diseases had the poorest quality of life. When controlling for the effects of gender, age, and cirrhosis, impact of chronic liver disease diagnosis on utility scores persisted only for the SF-6D, with HCV patients having significantly poorer health than HBV patients. In conclusion, SF-6D provides not only a generic assessment of HRQL but also a utility score that can be used for economic analysis of patients with chronic liver disease.

UNLABELLED: Although chronic hepatitis C (CH-C) has consistently been shown to impair patients' health-related quality of life (HRQL), the impact of chronic hepatitis B (CH-B) on HRQL has not been fully explored. AIM: Compare HRQL between patients with CH-B, CH-C, primary biliary cirrhosis (PBC) and healthy controls. DESIGN: Three HRQL questionnaires [Chronic Liver Disease Questionnaire (CLDQ), Short Form 36 (SF-36) and the Health Utility Index (HUI Mark-2 and Mark-3)] were administered prospectively. Additional clinical and laboratory data and normative data for healthy individuals, were available. ANALYSIS: Scores were compared using analysis of variance and multiple regression. RESULTS: One hundred and forty-six patients with CH-B, CH-C and PBC were included [mean age 47.1 years (+/-11.6), 41% female, 33% cirrhosis]. CH-C and PBC patients scored the lowest on all CLDQ, SF-36 and HUI domains compared with CH-B patients and healthy controls. CH-B patients had scores similar to the healthy population, measured by most CLDQ and SF-36 scales. However, the HUI scores for CH-B patients showed more impairment than population norms. Having CH-B and not having cirrhosis were predictive of utility and HRQL scores in multivariate models. CONCLUSIONS: CH-B patients have better HRQL than CH-C, PBC and population norms. CH-B patients' overall utility scores are lower than population norms.

BACKGROUND: The impact of superimposed non-alcoholic fatty liver disease (NAFLD) is well established in patients with chronic hepatitis C (CH-C), but the impact in patients with chronic hepatitis B (CH-B) is less clear. AIM: This study aims to evaluate the prevalence of NAFLD in patients with CH-B and the association with viral and host factors, particularly in patients with metabolic syndrome (MS). DESIGN: Data from patients with CH-B was obtained from our databases. Patients with excessive alcohol use were excluded. Hepatitis B virus (HBV) genotyping by INNO-LIPA was available for some patients. The presence of MS was defined according to the Adult Treatment Panel III (ATP III). All biopsies were read by two hepatopathologists using Metavir, modified histologic activity index (MHAI), as well as a NAFLD pathologic protocol. Patients were classified as (1) those without NAFLD; (2) those with simple hepatic steatosis; (3) and those with superimposed non-alcoholic steatohepatitis (NASH). Factors associated with superimposed NAFLD, its subtypes, and hepatic fibrosis were also analysed. RESULTS: Subjects included 153 HBV patients [66% male, age 50.5+/-27.5 years, body mass index 24.7+/-3.7 kg/m(2), waist 83.2+/-10.9 cm; 8.5% Caucasian, 67% Asian, aspartate aminotransferase (AST) 63.2+/-88.2 IU/l, alanine aminotransferase (ALT) 98.6+/-164.6 IU/l, glucose 111.6+/-50.5 mg/dl, HBV-DNA 1.8 x 10(8)+/-1.9 x 10(6) copies/ml, 7% with MS, 13% with diabetes, 20% with arterial hypertension and 8.5% with dyslipidaemia]. Liver biopsy was available for 64 subjects [19% had superimposed NAFLD, 13% had superimposed NASH, 86% had some degree of fibrosis, and 39% had advanced fibrosis (Ishak >3)]. Patients with HBV and superimposed NASH were significantly older (55 vs. 42 years, P=0.008), more likely to have hypertension (63% vs. 15%, P=0.006) and dyslipidaemia (50% vs. 8%, P=0.006), and had a larger waist circumference (92 vs. 83 cm, P=0.03). The presence of fibrosis was associated with higher waist circumference (84 vs. 80 cm, P=0.03), higher HBV-DNA (1.9 x 10(8) vs. 5 x 10(6) copies/ml, P=0.005), and elevated ALT >40 IU/l (73.6% vs. 33.3%, P=0.02). CONCLUSIONS: The components of MS (obesity, hypertension, and dyslipidaemia) are associated with the presence of NASH in patients with CH-B. The presence of hepatic fibrosis seems to be associated with known host and viral factors as well as the presence of abdominal obesity.

In addition to chronic hepatitis, many individuals infected with hepatitis C virus (HCV) suffer from fatigue, which may compromise their health-related quality of life (HRQL). To assess systematically health-related quality of life (HRQL) in patients with chronic hepatitis C and to determine if any clinical, biochemical, virologic, demographic, and histologic features are associated with HRQL status. In this cross-sectional observational study, one hundred thirty patients with chronic HCV infection (HCV RNA positive by PCR) and 61 healthy controls were enrolled from a tertiary care teaching medical center. All patients and controls completed one generic HRQL questionnaire (MOS SF-36) and one liver-disease specific instrument (Chronic Liver Disease Questionnaire, CLDQ). Ninety-five HCV patients and all the controls also completed a fatigue questionnaire (Chronic Fatigue Screener, CFS) and had immunologic markers determined (Cryoglobulin, Soluble IL-2 receptors, Rheumatoid Factor). We compared the HRQL of HCV-infected patients to the controls and, using data from other studies, to the general population, patients with diabetes, and patients with chronic low back pain. Patients with chronic HCV had greater HRQL impairment than healthy controls and those with type II diabetes. Fatigue was the most important symptom with negative impact on HRQL. Sixty-one percent of HCV-infected patients reported fatigue-related loss of activity. Additionally, other factors associated with HRQL were gender and histologic cirrhosis. Chronic HCV infection has a profound negative impact on patients' HRQL. Disabling fatigue is the most important factor that contributes to loss of well-being in this relatively young group of patients.

UNLABELLED: Infection with HCV leads to an array of symptoms that compromise health-related quality of life (HRQL). Chronic hepatitis C is treated primarily with pegylated interferon (peg-IFN) and an inosine 5' monophosphate dehydrogenase inhibitor, ribavirin (RBV), with the goal of achieving a sustained virologic response (SVR). SVR reduces the rate of hepatic fibrosis and other disease-related complications and, in turn, increases HRQL. Although combination therapy with peg-IFN and RBV produces SVRs in more than 50% of treated patients, it is associated with side effects that can reduce short-term HRQL, can lead to dose reductions and discontinuations, and may impair treatment response. Fatigue and depression are common symptoms of chronic HCV infection that may also be caused by IFN-based therapy. Hemolytic anemia and IFN-mediated bone marrow suppression are well-known consequences of IFN/RBV therapy, often resulting in dose reductions or discontinuations, and have the potential to affect SVR rates. Management of these symptoms is vital to successful outcomes and generally relies on therapy that is adjunctive to the primary treatment of the viral infection itself. Several new drugs with the potential to increase SVR rates without compromising HRQL are in development. CONCLUSION: The relationship of chronic HCV infection, treatment, and HRQL is complex. Successful treatment of chronic hepatitis C requires an understanding of the intricacies of this relationship and appropriate management of treatment-related symptoms.
