Independent Predictors of Fibrosis in Patients With Nonalcoholic Fatty Liver Disease

BACKGROUND & AIMS Nonalcoholic fatty liver disease (NAFLD) is a common cause of chronic liver disease. We investigated factors associated with advanced fibrosis in NAFLD. METHODS The study included 432 patients with histologically proven NAFLD (26.8% with nonalcoholic steatohepatitis [NASH] and 17.4% with moderate-to severe fibrosis). NASH was defined as steatosis, lobular inflammation, and ballooning degeneration with or without Mallory-Denk bodies and/or fibrosis. Fibrosis was classified into 2 groups: those with no or minimal fibrosis and those with moderate-to-severe fibrosis. Groups were compared using Mann-Whitney and chi-square method analyses. A model was constructed using a stepwise bidirectional method; its predictive power was measured using a 10-fold cross-validation technique. RESULTS Patients with NASH were more likely to be male (P < .0001); have lower hip-to-waist ratios (P = .03); were less likely to be African American (P = .06); have higher levels of alanine aminotransferase (ALT; P < .0001), aspartate aminotransferase (AST; P < .0001), and serum triglycerides (P = .0154), but lower levels of high-density lipoprotein cholesterol (P < .0001). Patients with moderate-to-severe fibrosis were older (P = .0245); more likely to be male (P = .0189), Caucasian (P = .0382), have diabetes mellitus (P = .0238), and hypertension (P = .0375); and have a lower hip-to-waist ratio (P = .0077) but higher serum AST (P < .0001) and ALT (P < .0001) levels. The multivariate analysis model to predict moderate-to-severe fibrosis included male sex, Caucasian ethnicity, diabetes mellitus, and increased AST and ALT levels (model P value < .0001). CONCLUSIONS In patients with NAFLD, diabetes mellitus and aminotransferase levels are independent predictors of moderate-to-severe fibrosis. They can be used to identify NAFLD patients at risk for advanced fibrosis.

Associations of chronic hepatitis C with metabolic and cardiac outcomes.

Chronic hepatitis C virus (CH‐C) infection is associated with metabolic conditions such as insulin resistance and type 2 diabetes (DM) and may increase the risk of cardiovascular diseases.

Effects of Sofosbuvir-Based Treatment, With and Without Interferon, on Outcome and Productivity of Patients With Chronic Hepatitis C

BACKGROUND & AIMS Interferon-based treatment of chronic hepatitis C virus (HCV) infection can negatively affect patient-reported outcomes (PROs) and work productivity (WP). We assessed these factors in patients with chronic hepatitis C treated with sofosbuvir and ribavirin, with or without pegylated interferon. METHODS The HCV-specific Quality of Life (Chronic Liver Disease Questionnaire-HCV version [CLDQ-HCV]), Functional Assessment of Chronic Illness Therapy-Fatigue, and Work Productivity and Activity Index: Specific Health Problem questionnaires were completed before, during, and after treatment of patients infected with HCV genotypes 2 or 3 who received sofosbuvir and ribavirin for 16 or 12 weeks (the FUSION study, n = 201) or patients infected with HCV genotype 1 who received pegylated interferon, sofosbuvir, and ribavirin for 12 weeks (the NEUTRINO study, n = 327). RESULTS Patients in each group of the FUSION study had similar PRO and WP scores at each time point (all comparisons, P > .05). Compared with baseline, patients had modest reductions in fatigue, HCV-specific quality of life, and WP and Activity Index scores during treatment (P = .02 to <.0001). However, by 4 weeks after treatment, all scores returned to baseline levels or higher. Subjects in the NEUTRINO study had greater reductions in these scores during treatment; most remained significant through 4 weeks after treatment (P < .05). Significant improvements in PROs were observed among patients with sustained virologic responses 12 weeks after treatment in the FUSION and NEUTRINO studies (all P < .05). In multivariate analyses after adjustment for confounders, interferon therapy was independently associated with worse PROs after 12 weeks of treatment. CONCLUSIONS On the basis of an analysis of 2 large clinical trials (FUSION and NEUTRINO), patient outcome and productivity are more negatively affected by the inclusion of pegylated interferon in treatment than by interferon-free regimens. Patients with sustained virologic responses 12 weeks after treatment had significant improvements in PROs in both studies.

Patient-reported outcomes in chronic hepatitis C patients with cirrhosis treated with sofosbuvir-containing regimens

Whether the presence of cirrhosis influences patient‐reported outcomes (PROs), including health‐related quality of life, during treatment with newly available anti‐HCV (hepatitis C virus) regimens is unclear. Our aim was to assess the association of cirrhosis with PROs in patients treated with sofosbuvir (SOF)‐containing regimens. Four PRO questionnaires (Short Form‐36 [SF‐36], Functional Assessment of Chronic Illness Therapy‐Fatigue [FACIT‐F], Chronic Liver Disease Questionnaire‐HCV (CLDQ‐HCV), and the Work Productivity and Activity Impairment Questionnaire: Specific Health Problem [WPAI‐SHP]) were administered to subjects receiving SOF and ribavirin (RBV; FUSION trial, N = 201, 34% cirrhosis; VALENCE trial: N = 333, 21% cirrhosis) and SOF, RBV, and pegylated interferon (Peg‐IFN; NEUTRINO trial: N = 327, 17% cirrhosis). HCV patients with cirrhosis showed significant impairment of PROs before initiation of treatment. During treatment, patients with cirrhosis treated with the IFN‐free regimen experienced moderate decline in their PRO scores (0.6%‐5.2% on a normalized scale of the summary scores; all P > 0.02). In contrast, patients with cirrhosis treated with IFN‐containing regimen showed decline in PRO scores that ranged from 3.4% to 16.0% (all P < 0.005). Nevertheless, by follow‐up week 12, no PRO decrement from baseline was observed in patients with cirrhosis regardless of the treatment regimen. Furthermore, in patients with cirrhosis with HCV who achieved sustained virological response at 12 weeks (SVR‐12), some improvement in PROs from baseline was observed. During treatment, changes in PRO scores were similar between patients with and without cirrhosis for both treatment regimens (all P > 0.05). Independent predictors of lower PROs in patients with cirrhosis included baseline depression, anxiety, fatigue, high HCV viral load, female gender, and receiving IFN‐containing treatment. Conclusions: Treatment with SOF+RBV with or without Peg‐IFN is tolerated by HCV patients with and without cirrhosis in terms of their PRO scores. After achieving SVR‐12 with the IFN‐free regimen, patients with cirrhosis showed improvement in some aspects of their PROs. (Hepatology 2014;59:2161–2169)

The patient's journey with chronic hepatitis C from interferon plus ribavirin to interferon- and ribavirin-free regimens: a study of health-related quality of life

Interferon and ribavirin negatively impact health‐related quality of life (HRQL) during treatment.

An In-Depth Analysis of Patient-Reported Outcomes in Patients With Chronic Hepatitis C Treated With Different Anti-Viral Regimens

OBJECTIVES:Interferon- and ribavirin (RBV)-containing regimens negatively impact patients’ experience. The aim of this study was to quantify the impact of different anti-viral regimens for hepatitis C on patients’ work productivity, fatigue, and other patient-reported outcomes (PROs).METHODS:The PRO data from multicenter multinational phase 3 clinical trials of sofosbuvir with and without interferon or RBV were retrospectively used. Treatment regimens were classified as interferon+RBV-containing, interferon-free RBV-containing, and interferon-free RBV-free. Four PRO instruments (SF-36, CLDQ-HCV, FACIT-F, and WPAI:SHP) were administered to subjects at baseline, during, and up to 24 weeks after treatment.RESULTS:We included 3,425 subjects with chronic hepatitis C infection with PRO data. Patients were 62.8% male, 62.2% treatment naive, 18.1% with cirrhosis, and 72.9% with HCV genotype 1. Of the study participants, 546 received interferon+RBV+sofosbuvir, 1,721 received sofosbuvir+RBV, and 1,158 received interferon- and RBV-free ledipasvir+sofosbuvir. At baseline, there were no difference in PROs between treatment groups (all P>0.01). During treatment, the decrements in PROs were up to −23.6% for the interferon+RBV group, up to −7.0% in the sofosbuvir+RBV group, whereas there was an improvement of up to +11.6% in the interferon-free RBV-free group (all P<0.0001). In multivariate analysis, the use of interferon was independently associated with up to −26.0% worsening of the PRO scores during treatment and the use of RBV with up to −9.0% worsening. After 12 weeks post-treatment, in patients with sustained virologic response-12, improvements were observed regardless of the regimen, and these improvements continued to increase by week 24 of follow-up.CONCLUSIONS:The use of interferon- and RBV-free regimens for HCV is associated with better patients’ experience and work productivity during treatment.

Sofosbuvir/velpatasvir improves patient-reported outcomes in HCV patients: Results from ASTRAL-1 placebo-controlled trial

BACKGROUND & AIMS The new pan-genotypic regimen [sofosbuvir (SOF) and velpatasvir (VEL)] for hepatitis C virus (HCV) has been associated with high efficacy. The aim of this study was to assess patient-reported outcomes (PROs) of this regimen. METHODS The PRO data (CLDQ-HCV, SF-36, FACIT-F, WPAI) came from the ASTRAL-1 study, a multicenter multinational blinded placebo-controlled phase 3 clinical trial of a fixed dose combination of SOF 400mg and VEL 100mg for patients with genotype 1, 2, 4, 5, and 6 compared to placebo for 12weeks. RESULTS 624 patients received active treatment [618 achieved sustained virologic response (SVR)], and 116 received placebo. The baseline PRO scores were similar. By treatment week 4, patients receiving SOF/VEL experienced improvements in general health (on average, +2.3points), emotional well-being (+3.4), FACIT-F (+1.3), and all domains of CLDQ-HCV (+2.1 to +7.3) (all p<0.005). On the other hand, the only PRO that improved in patients receiving placebo was the worry domain of CLDQ-HCV: +4.6 (p=0.002). By the end of treatment, improvement in PRO scores with SOF/VEL continued, and no improvement was noted in the placebo. Improvement in PROs were also noted 12 and 24weeks post-treatment: +3.7, on average, in patients with SVR-12 after SOF/VEL vs. -2.6, on average, in the placebo arm (p<0.005). Multivariate analysis showed that treatment-emergent changes in PROs were predicted by receiving SOF/VEL for some summary PRO score (p<0.005). CONCLUSIONS This placebo-controlled trial shows that patients treated with SOF/VEL experience significant improvement of their PROs during treatment and after achieving SVR. LAY SUMMARY In patients with chronic hepatitis C infection, health-related quality of life and work productivity are often impaired due to HCV-related fatigue. Treatment of hepatitis C with interferon-based regimens, which was the standard of care for all HCV patients until recently, had substantial and potentially debilitating side effects. These regimens caused additional impairment in health-related quality of life and work productivity during treatment and shortly after treatment cessation. The newly developed interferon-free combination of sofosbuvir and velpatasvir has been shown to improve health-related quality of life during treatment, and lead to an improvement in a number of indicators of patient-reported outcomes after successful clearance of HCV and achieving sustained virologic response.

Depression in Patients with Nonalcoholic Fatty Liver Disease and Chronic Viral Hepatitis B and C

BACKGROUND Patients with chronic liver disease (CLD) and depression may be at a higher risk for various complications, including impaired quality of life and more advanced liver disease. The purpose of this study was to determine the prevalence of depression in CLD patients (non-alcoholic fatty liver disease (NAFLD), Hepatitis B (HBV), and Hepatitis C (HCV)) and to identify potential clinical and laboratory correlates of depression in these patients. METHODS We used a database of CLD patients that contains extensive clinical (including self-reported depression) and laboratory data for each patient. We compared the prevalence of depression in patients with HBV, HCV, and NAFLD. We also used regression models to find independent predictors of depression in these patients. RESULTS Of 878 CLD patients, 207 (23.6%) had a diagnosis of depression (NAFLD 27.2%, HCV 29.8%, and HBV 3.7%). Examination of predictors of depression differed by the type of chronic liver disease. For NAFLD, independent predictors of depression were the presence of hypertension, smoking, history of lung disease, being female, and non-African-American. For HBV patients, the only independent predictor of depression was excessive alcohol consumption (defined as >10 g/d), while for HCV patients, independent predictors were being female and non-Asian, presence of fatigue, and excessive alcohol intake. CONCLUSIONS This study demonstrates that individuals with NAFLD and HCV have a higher prevalence of depression than HBV patients and the rates of depression reported for the general population. The most consistent correlates of depression status in CLD patients are being female and excessive alcohol consumption.

A phase II dose finding study of darbepoetin alpha and filgrastim for the management of anaemia and neutropenia in chronic hepatitis C treatment

Summary.  Dose reductions of pegylated interferon alpha and ribavirin may be avoided by using growth factors. This phase II clinical trial assesses the dose, efficacy and safety of darbepoetin alpha and filgrastim for treatment of anaemia and neutropenia associated with combination therapy for hepatitis C virus (HCV). Chronic hepatitis C patients (n = 101) received pegylated interferon alpha‐2b (1.5 μg/kg once weekly) and ribavirin (800–1400 mg once daily). Patients with anaemia [haemoglobin (Hb) ≤ 10.5 g/dL] received darbepoetin alpha (3 μg/kg once every 2 weeks); the dose was titrated to achieve a Hb level of 12.0 g/dL. Patients with neutropenia [absolute neutrophil count (ANC) ≤ 0.75 × 109/L] received filgrastim with the dose titrated from 150 μg QW to 300 μg thrice weekly to maintain ANC ≥ 0.75 × 109/L and <10 × 109/L. During antiviral therapy, 52% of patients required darbepoetin alpha, filgrastim or both. Hb at the time of darbepoetin alpha initiation was 10.2 ± 0.4 g/dL. After 81 days of darbepoetin alpha, Hb increased by 1.9 ± 1.0 g/dL to 12.1 ± 1.1 g/dL (P < 0.0001). Filgrastim resulted in a significant increase in ANC [0.75 ± 0.16 × 109/L to 8.28 ± 5.67 × 109/L (P < 0.0001)]. In treatment‐naïve patients, 48% achieved sustained virological response (SVR), whereas 27% of patients previously treated with a course of pegylated interferon alpha achieved SVR. Low viral load, nongenotype 1 and treatment with growth factors were independently associated with SVR. Mild and severe anaemia were associated with quality of life impairments. Darbepoetin alpha resulted in an improvement in the Vitality domain of Short Form‐36. No significant adverse events were related to growth factors. During anti‐HCV therapy, filgrastim improved neutropenia and darbepoetin alpha improved both anaemia and quality of life. Future randomized clinical trials are needed to establish the impact of growth factors in improving sustained virological response.

Non-alcoholic steatohepatitis (NASH) in patients with polycystic ovarian syndrome (PCOS)

Abstract Background. Both non-alcoholic steatohepatitis (NASH) and polycystic ovary syndrome (PCOS) are associated with metabolic syndrome (MS) and insulin resistance (IR). Except for a few case reports, there are no systematic assessments of NASH in PCOS patients. Aim. To determine the prevalence of NASH and independent factors associated with NASH in a cohort of patients with documented PCOS. Methods. Patients with established diagnosis of PCOS and matched controls (matched for gender, age, and body mass index (BMI)) were included in the study. Causes of other liver diseases were systematically excluded by clinical and laboratory tests. Excessive alcohol use was defined as alcohol consumption of greater than 10 g/day. All liver biopsies were read by a single pathologist blinded to the clinical data. Histologic NASH was defined as steatosis with lobular inflammation and ballooning degeneration of hepatocytes with or without Mallory–Denk bodies or pericellular fibrosis. Univariate and multivariate analyses with logistic regression were performed to compare PCOS to matched controls. Results. Sixty-six patients were included in the study (34 PCOS and 32 matched controls). Of PCOS patients, 73% had a liver biopsy while 78% of the matched controls had a liver biopsy. In comparing PCOS patients to the matched controls, clinical (BMI, waist circumference, type 2 diabetes, MS, or its components, any alcohol consumption in the prior year, ethnic background, age, gender, etc.) and laboratory data (aminotransferases, ferritin, glucose, etc.) were not significantly different (p > 0.05). However, PCOS patients tended to have more histologic NASH on their liver biopsies (44.0% vs. 20.8%, p = 0.08). Independent predictors of histologic NASH in PCOS patients were elevated aspartate aminotransferase (AST), high triglycerides and small amounts of alcohol consumption (p = 0.019, 10-fold cross-validated AUC = 0.80, 95% CI = 0.56–0.94). Although about half of PCOS patients did not report any alcohol consumption, 50% did report rare alcohol use. In fact, PCOS patients with histologic NASH tended to report higher alcohol consumption per week than PCOS without NASH (3.80 ± 6.16 vs. 1.11 ± 1.87 g/week, p = 0.1). Nevertheless, these amounts of alcohol consumption were quite minimal. Conclusions. Despite similar clinical and laboratory profiles to the matched controls, PCOS patients seem to have more histologic NASH. Although alcohol consumption was rare for both PCOS and controls, even rare alcohol consumption in PCOS patients was independently associated with histologic NASH.
