Alcohol consumption upon direct-acting antiviral therapy for hepatitis C among persons with human immunodeficiency virus in the United States. Drug Alcohol Depend 2022; 241:109673. [PMID: 36332596 PMCID: PMC9810271 DOI: 10.1016/j.drugalcdep.2022.109673] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/06/2022] [Revised: 10/19/2022] [Accepted: 10/19/2022] [Indexed: 01/05/2023]
Abstract
BACKGROUND Direct-acting antivirals (DAA) are highly effective against hepatitis C virus (HCV) infection among persons with human immunodeficiency virus (PWH). However, alcohol use post-DAA treatment poses a continued threat to the liver. Whether the focus on liver health alone during HCV treatment can impact alcohol consumption is unclear. Therefore, we examined the change in alcohol use among HCV-coinfected PWH who received DAA therapy by non-addiction medical providers. METHODS In our longitudinal clinical cohort study, we identified HCV-coinfected PWH who received interferon-free DAA therapy between January 2014 and June 2019 in the Centers for AIDS Research Network of Integrated Clinical Systems. The Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) was the alcohol screening instrument. We used mixed-effects logistic regression models to estimate the longitudinal change in alcohol use upon DAA therapy. RESULTS Among 738 HCV-coinfected PWH, 339 (46 %) reported any alcohol use at the end of HCV treatment, including 113 (15 %) with high-risk use (i.e., AUDIT-C ≥3 for women, ≥4 for men). Concurrently, 280 (38 %) PWH noted active drug use, and 357 (48 %) were currently smoking. We observed no changes in the odds of any alcohol or high-risk alcohol use over time with DAA therapy. Findings were similar in the PWH subgroup with a history of alcohol use before DAA treatment. CONCLUSIONS For PWH with HCV, alcohol use did not change following interferon-free DAA treatment by non-addiction medical providers. Thus, clinicians should consider integrating targeted alcohol use interventions into HCV care to motivate reduced alcohol consumption and safeguard future liver health.

Abstract
BACKGROUND To increase cure rates for Hepatitis C, barriers to treatment adherence and completion must be identified and overcome. AIMS This study systematically reviewed evidence on the psychological, lifestyle and social determinants of achieving viral eradication with antiviral therapy. METHODS An electronic search strategy was used to identify relevant studies that examined psychological, lifestyle and social factors related to achieving a sustained virological response (SVR). RESULTS Thirty-four studies that matched our criteria were identified. Of the factors that predict response to treatment, Asian ethnicity was an independent predictor of SVR. We found an indirect relationship between diet and SVR, with non-responders to treatment consuming more polyunsaturated fatty acids, fats and carbohydrates than those who attained SVR. The effect of alcohol consumption relied on the amount consumed; fewer than 30 grams daily had no effect on SVR, whereas >70 grams daily had an adverse impact on a patient's ability to achieve SVR, with termination rates up to 44% in those who drank >2 drinks a day. Patients with psychiatric illnesses had comparable SVR rates to controls if they continued psychological therapy (average 42%), although discontinuation rates were high with 11 studies reporting rates from 14 to 48%. CONCLUSIONS There are major gaps in current knowledge of the impact of variables such as diet, exercise, attitudes and coping skills on cure rates in chronic Hepatitis C. Those who drink limited amounts of alcohol or have psychiatric disorders should be offered treatment for their disease, with adjunctive education and support to improve treatment completion.

Abstract
AIM Optimal management of hepatitis C virus (HCV) infection is controversial in heavy drinkers. We compared the management of HCV infection of heavy drinkers with that of patients without a history of alcohol abuse. METHODS In a retrospective case-control study, 69 HCV-infected heavy drinkers [daily alcohol consumption at referral above 60 g/day, hereafter 'alcohol group'] were compared with matched HCV-infected patients with low alcohol consumption (<40 g/day, 'control group'). RESULTS Patients of the 'alcohol group' were younger (42 vs. 45 years, P = 0.05), more often male (69.6 vs. 56.5%, P = 0.11) and had been infected by intravenous drug use (85.5 vs. 45.0%, P < 0.0001). The percentage of patients with a recommendation for treatment according to the French 2002 consensus (bridging fibrosis or genotype 2 or 3) was 52 of 69 (75.4%) in both groups, while the proportion of patients treated was higher in the control group (71.0 vs. 44.9%, P = 0.002). In the 'alcohol group', patients had better access to treatment if they were employed or consumed 170 g/day or less at first referral. Sustained virological response (SVR) was obtained in 10 of 31 patients (32.3%) of the 'alcohol group' vs. 8 of 31 patients (25.8%) of the control group matched for genotype and type of treatment (P = 0.58). CONCLUSION Heavy drinkers are less often considered for antiviral therapy compared with patients without a history of alcohol abuse. However, once treatment is actually initiated, SVR rates are comparable with those achieved in non-drinkers despite the continuation of alcohol consumption during therapy in some patients.

Abstract
UNLABELLED Treatment of chronic hepatitis C infection (HCV(+) ) has historically been shown to be less effective in patients with a heavy drinking history. The effect of moderate and heavy alcohol use on treatment with pegylated interferon-alpha and ribavirin (P/R) in an insured household population has not been previously reported. We investigated the effect of alcohol on treatment outcome in a cohort of 421 treatment-naïve HCV(+) patients, members of an integrated health care plan treated with P/R between January 2002 and June 2008. A detailed drinking history was obtained for 259 (61.5%) eligible patients. Regular drinking was reported by 93.1% of patients before HCV diagnosis, by 30.9% between HCV diagnosis and treatment, by 1.9% during treatment, and 11.6% after the end of treatment. Heavy drinking patterns were reported by 67.9%, 63.5% of patients drank more than 100 kg of ethanol before initiating HCV treatment, and 29.3% reported abstaining less than the required 6 months before treatment. Despite these reports of heavy drinking, sustained virological responses (SVRs) were obtained in 80.2% of patients with HCV genotypes 2 or 3 and 45.1% of patients with genotypes 1, 4, or 6. Pretreatment drinking patterns and total alcohol intake were both unrelated to SVR rates. Abstaining less than 6 months before treatment was related to lower SVR rates in moderate, but not heavy, drinkers. HCV treatment relapse was unrelated to drinking after treatment ended. CONCLUSION The amount of alcohol consumed before HCV treatment did not have a negative effect on treatment outcomes in our population. A history of heavy drinking should not be considered a deterrent to HCV treatment in members of an integrated health care plan who are closely monitored.

Abstract
Hepatitis C virus (HCV) is a blood-borne pathogen that was identified as an etiologic agent of non-A, non-B hepatitis in 1989. HCV is estimated to have infected at least 170 million people worldwide. The majority of patients infected with HCV do not clear the virus and become chronically infected, and chronic HCV infection increases the risk for hepatic steatosis, cirrhosis, and hepatocellular carcinoma. HCV induces oxidative/nitrosative stress from multiple sources, including inducible nitric oxide synthase, the mitochondrial electron transport chain, hepatocyte NAD(P)H oxidases, and inflammation, while decreasing glutathione. The cumulative oxidative burden is likely to promote both hepatic and extrahepatic conditions precipitated by HCV through a combination of local and more distal effects of reactive species, and clinical, animal, and in vitro studies strongly point to a role of oxidative/nitrosative stress in HCV-induced pathogenesis. Oxidative stress and hepatopathogenesis induced by HCV are exacerbated by even low doses of alcohol. Alcohol and reactive species may have other effects on hepatitis C patients such as modulation of the host immune system, viral replication, and positive selection of HCV sequence variants that contribute to antiviral resistance. This review summarizes the current understanding of redox interactions of HCV, outlining key experimental findings, directions for future research, and potential applications to therapy.

Abstract
BACKGROUND Patients with chronic hepatitis C virus (HCV) infection have high rates of alcohol consumption, which is associated with progression of fibrosis and lower response rates to HCV treatment. AIMS This prospective cohort study examined the feasibility of a 24-week integrated alcohol and medical treatment to HCV-infected patients. METHODS Patients were recruited from a hepatology clinic if they had an Alcohol Use Disorders Identification Test score >4 for women and >8 for men, suggesting hazardous alcohol consumption. The integrated model included patients receiving medical care and alcohol treatment within the same clinic. Alcohol treatment consisted of 6 months of group and individual therapy from an addictions specialist and consultation from a study team psychiatrist as needed. RESULTS Sixty patients were initially enrolled, and 53 patients participated in treatment. The primary endpoint was the Addiction Severity Index (ASI) alcohol composite scores, which significantly decreased by 0.105 (41.7% reduction) between 0 and 3 months (P < 0.01) and by 0.128 (50.6% reduction) between 0 and 6 months (P < 0.01) after adjusting for covariates. Alcohol abstinence was reported by 40% of patients at 3 months and 44% at 6 months. Patients who did not become alcohol abstinent had reductions in their ASI alcohol composite scores from 0.298 at baseline to 0.219 (26.8% reduction) at 6 months (P = 0.08). CONCLUSION This study demonstrated that an integrated model of alcohol treatment and medical care could be successfully implemented in a hepatology clinic with significant favorable impact on alcohol use and abstinence among patients with chronic HCV.

Abstract
OBJECTIVES The objective of this study was to assess to what extent HIV/HCV co-infected patients underreport alcohol use to their physician with respect to self-reports from self-administered questionnaires (SAQ) and identify correlates of alcohol underreporting during face-to-face medical interviews (FMI). DESIGN ANRS-CO13-HEPAVIH is a French multi-center cohort of HIV/HCV co-infected patients. METHODS Data were collected at enrolment using both SAQ and FMI while clinical data were retrieved from medical records. Alcohol consumption was assessed through SAQ and compared with FMI patient reports. Correlates of underreporting alcohol consumption during FMI with respect to SAQ were identified using logistic regression analysis. RESULTS Among 544 patients, 37% were classified as alcohol abusers according to AUDIT-C in the SAQ. During FMI, 14% underreported alcohol consumption. The following correlates were independently associated with underreporting alcohol consumption in FMI: not receiving HIV treatment, being followed up by a hepatologist for HCV infection and reporting a history of injecting drug use. CONCLUSIONS These results highlight the difficulties in alcohol consumption assessment which HCV specialists may face when suggesting to their HIV/HCV co-infected patients that they cease drinking completely. Patient awareness about the real need to reduce their alcohol use before starting HCV therapy may also contribute to underreporting. Innovative strategies for alcohol risk-reduction, including the promotion of controlled consumption and access to multidisciplinary teams, should be implemented for HIV/HCV co-infected patients in order to reduce barriers to HCV treatment.

Abstract
One hundred and seventy million people worldwide live with chronic hepatitis C. Heavy alcohol use plays a key role in progression of the illness and is a contraindication to hepatitis C treatment. Despite the ubiquity of alcohol in Western society as a marker of celebration and sociability, there has been little research addressing the meanings of alcohol use and the dilemmas involved in ceasing or limiting consumption for affected people. This article fills a gap in the literature by addressing the meanings and practices of alcohol use for people with hepatitis C. Data are drawn from a qualitative study exploring the experiences of 40 people living with hepatitis C in New Zealand and Australia. Participants described a number of tensions and dilemmas involved in their relationship with alcohol, illustrating a complex and under-researched interplay of factors that inform drinking practice.

Abstract
Substance abusers account for the largest number of hepatitis C infected cases in developed countries. We describe a care model for treating current or former substance abusers with antiviral therapy for hepatitis C virus (HCV) infection. The care model involved hepatitis nurses, a psychologist, infectious disease specialist and primary care physicians. Clients met selection criteria including regular attendance at clinic appointments and social stability. Use of alcohol and illicit substances was monitored with urine toxicology screens. The association between substance use, rates of completion of therapy and rates of response were assessed using multivariable regression analyses. A total of 109 clients (75 with genotype 1/4 and 34 with genotype 2/3) received at least one injection with pegylated interferon between November 2002 and January 2006. Treatment completion rates of 61 and 74% were achieved for genotypes 1/4 and 2/3, respectively. Treatment response rates in an intention to treat analysis were 51% for genotypes 1/4 and 68% for genotypes 2/3. A positive urine toxicology screen indicating use of illicit substances 6 months prior to initiating therapy was significantly associated with lower rates of treatment completion but not lower rates of sustained virological response. A positive urine screen indicating use of alcohol prior to therapy was significantly associated with lower rates of completion and lower rates of response. Rates of completion and response are comparable to non-substance abusing populations. Antiviral therapy for HCV infection can be successful within the context of ongoing care for substance abuse for carefully selected patients.

Abstract
Due to their high prevalence in the general population, alcohol use and abuse can be associated with hepatitis B and C virus infections and it has been demonstrated that alcohol plays a role as a co-morbid factor in the development of liver disease. There is evidence that alcohol abuse accelerates the progression of liver fibrosis and affects the survival of patients with chronic hepatitis C. The mechanism by which alcohol worsens hepatitis C virus-related liver disease has not been fully clarified, but enhanced viral replication, increased oxidative stress, cytotoxicity and impairment of immune response could play a relevant role. Alcohol abuse also seems to reduce both sensitivity to interferon and adherence to treatment. It sounds reasonable to presume that the mechanisms enhancing liver damage in patients affected by hepatitis B are similar to those involved in hepatitis C virus infection. However, more studies are warranted to improve our knowledge about the interaction between alcohol intake and hepatitis B virus infection. In conclusion alcohol abuse is associated with an accelerated progression of liver injury, leading to an earlier development of cirrhosis, higher incidence of hepatocellular carcinoma, and higher mortality. Abstinence could reverse some of these deleterious effects.

Abstract
HCV plays a key role as chronic antigenic driver in inducing a clonal expansion of B-lymphocytes. The hypothesis that previous immunological pattern, when expression of an exaggerated immune reaction, could affect the response to IFN therapy was tested. Using a longitudinal database, the outcomes of 124 HCV-positive patients, genotype 1b only, with circulating HCV RNA, were analyzed by a retrospective cohort design. Immunological disorder-related clinical features and visceral organ involvement were thoroughly investigated in addition to laboratory data focusing on the presence of cryoglobulins, rheumatoid factor, antinuclear antibody, complement, circulating immunocomplexes and mono-oligoclonal gamma-globulin expansion. Eighty-four patients with and forty patients without abnormal immunological status, presenting a low fibrosis score, were identified. The whole naive population was treated by IFN monotherapy at the classical schedule for six or, alternatively, up to twelve months. Of the 124 patients, 28 showed a sustained response while 50 were non-responders and 46 were relapsers. Particularly, among the 84 patients with abnormalities of the immunological status, skin involvement was detected in 71 patients and hypocomplementemia was found in 69 patients, emerging as independent predictors for the lack of response. Conclusively, a peculiar immunological phenotype, ascertained by clinical and/or laboratory findings, is associated to a lack of IFN response and could be considered a further predictive factor.

Abstract
Therapy for chronic hepatitis C has improved dramatically over the past 20 years. Unfortunately, approximately 50% of those treated do not have a durable response to therapy. Non-responders and relapsers after previous interferon-based therapy are particularly challenging with regard to clinical management. This article provides a general overview of the treatment of hepatitis C and reviews present data regarding management of patients with chronic hepatitis C who are non-responders or relapsers after previous treatment. The review ends with the authors' opinion regarding present management of non-responders and relapsers and future emerging therapies.

Abstract
Hepatitis C virus (HCV) is an RNA virus of the Flaviviridae family that is estimated to have infected 170 million people worldwide. HCV can cause serious liver disease in humans, such as cirrhosis, steatosis, and hepatocellular carcinoma. HCV induces a state of oxidative/nitrosative stress in patients through multiple mechanisms, and this redox perturbation has been recognized as a key player in HCV-induced pathogenesis. Studies have shown that alcohol synergizes with HCV in the pathogenesis of liver disease, and part of these effects may be mediated by reactive species that are generated during hepatic metabolism of alcohol. Furthermore, reactive species and alcohol may influence HCV replication and the outcome of interferon therapy. Alcohol consumption has also been associated with increased sequence heterogeneity of the HCV RNA sequences, suggesting multiple modes of interaction between alcohol and HCV. This review summarizes the current understanding of oxidative and nitrosative stress during HCV infection and possible combined effects of HCV, alcohol, and reactive species in the pathogenesis of liver disease.

Abstract
BACKGROUND Since the discovery of the hepatitis C virus (HCV), extensive literature has emerged on alcohol and HCV interaction. GOAL To understand the impact of alcohol and HCV infection on the severity of liver disease and the mechanisms of interaction between the two. STUDY Of 1269 articles (1991 to 2006) searched through MEDLINE and cited cross references, 133 were thoroughly reviewed to assess: (a) prevalence of combined alcohol use and HCV, (b) severity of liver disease (c) treatment response, and (d) mechanisms of interaction between HCV and alcohol. Data on study design, patient demographics, diagnostic tests used, and study outcomes were extracted for critical analysis. RESULTS Prevalence of HCV is 3-fold to 30-fold higher in alcoholics compared with the general population. Patients with HCV infection and alcohol abuse develop more severe fibrosis with higher rate of cirrhosis and hepatocellular cancer compared with nondrinkers. Increased oxidative stress seems to be the dominant mechanism for this synergism between alcohol and the HCV. Abstinence is the key to the management of liver disease due to HCV and alcohol. Data have shown that lower response rates to interferon in alcoholics with HCV infection are likely due to noncompliance. CONCLUSIONS Alcoholics with HCV infection have more severe liver disease compared with nondrinkers. Patients should be encouraged to enroll in rehabilitation programs so as to improve treatment adherence and response.

Abstract
BACKGROUND Alcohol use and human immune deficiency virus (HIV) infection are both associated with accelerated progression of hepatitis C virus (HCV) disease and reduced response rates to interferon therapy. In this study, we assessed the prevalence of barriers to interferon treatment in a population of HIV/HCV-coinfected patients with current or past alcohol problems and the extent to which they received treatment to address the barriers. METHODS This is a cross-sectional, descriptive analysis of baseline data from a prospective study assessing the impact of HCV and alcohol use on HIV disease progression. Using consensus guidelines, subjects were categorized as having absolute, relative, or no contraindications to interferon therapy for HCV. Absolute contraindications to treatment included heavy alcohol use, decompensated liver disease, CD4 cell count <100 cells/microL, recent needle sharing, and suicidal ideation. Relative contraindications included moderate alcohol use, recent injection drug use, depressive symptoms, and CD4 cell count from 100 to 199 cells/microL. RESULTS Of 401 HIV-infected subjects, 200 were HCV RNA-positive. Fifty-three percent had an absolute contraindication to interferon therapy, 35% a relative but no absolute contraindication, and only 12% had no contraindication. Of those with an absolute contraindication, 61% reported heavy drinking and the majority (88%) had multiple contraindications. These contraindications were present despite the fact that over 50% were in receipt of substance abuse and mental health treatment. CONCLUSIONS Continued alcohol and drug use as well as depressive symptoms are the major barriers to interferon therapy in HCV/HIV-coinfected subjects and these barriers persist despite high treatment rates for these problems. Therefore, more intensive treatments of alcohol, drug, and mental health issues are needed to improve HCV treatment eligibility in HCV/HIV-coinfected persons.

Abstract
BACKGROUND & AIMS Patients with hepatitis C virus (HCV) infection who use alcohol have been excluded from clinical trials; therefore, outcomes with antiviral therapy are unknown. The aim of the study was to determine the impact of alcohol use on HCV treatment outcomes. METHODS Subjects using alcohol were categorized as follows: no alcohol versus regular alcohol use, quantity consumed (none, <6 drinks/day, >/=6 drinks/day), CAGE score <2 or >/=2, and recent alcohol use (past 12 months). Patients were treated with interferon plus ribavirin. RESULTS A total of 4061 subjects were enrolled, and 726 (18%) received treatment. Alcohol use (past and within 12 months) reduced treatment candidacy. Past alcohol use did not affect the end-of-treatment response, sustained virologic response (SVR), and treatment discontinuation rates. However, recent alcohol use resulted in higher treatment discontinuation (40% vs 26%; P = .0002) and tended to reduce the SVR (14% vs 20%; P = .06), but when patients who discontinued treatment were excluded from analysis, the trend in favor of nondrinkers for SVR disappeared (25% vs 23%). These findings were also consistent in subgroup analyses on race and genotype. CONCLUSIONS Eligibility for anti-HCV treatment was reduced in past and recent drinkers. Recent alcohol use was associated with increased treatment discontinuation and lower SVR. However, patients who use alcohol and completed the treatment had a response comparable to that of nondrinkers. Patients with a history of alcohol use should not be excluded from HCV therapy. Instead, additional support should be provided to these patients to ensure their ability to complete treatment.

Abstract
Hepatitis C virus (HCV) infection is highly prevalent among drug users. While there are antiviral medications available to combat the virus, the medication regimen is quite arduous, presenting special issues for drug users. We examined the challenges and benefits of using residential substance user treatment programs as venues for clients to undergo HCV medication regimens. Analyses of qualitative data collected from clients and staff in 2003 at four residential substance user treatment programs in the U.S. indicate that challenges primarily include issues involving the medications' side effects, and both financial and communication concerns. Benefits especially involve clients' feelings that they are being proactive in addressing health issues in an environment that provides much-needed support. Findings illuminate the complex issues involved for both clients and the programs, and some steps that programs can take to better support HCV-infected clients regarding HCV medication concerns.

Abstract
BACKGROUND/AIMS Alcohol use and hepatitis C are prominent risk factors for liver injury and this review offers the current understanding of each factor's effects on liver disease. METHODS A Medline database search was preformed for English articles with a focus on alcohol, hepatitis C and liver disease. Article citations were also considered for further applicable articles, and the strongest studies were included in our review. RESULTS Up to 60% of patients with hepatitis C have a past history of alcohol use. In patients with hepatitis C, chronic alcohol consumption of more than 5 drinks/day increases the rate of liver fibrosis, risk for cirrhosis, hepatocellular carcinoma, and, possibly, death from liver disease. Numerous studies have further found that even moderate amounts of alcohol can be detrimental to hepatitis C patients. The prevalence of hepatitis C is higher in alcoholics with advanced liver disease than in alcoholics without liver disease. Also, recent alcohol use decreases the response rate to interferon treatment. CONCLUSIONS Hepatitis C and alcohol use are often co-occurring risk factors for liver disease, and though their interaction is not clear, it is known that heavy drinking significantly promotes liver disease progression.

Abstract
Failure of interferon-alpha (IFN-alpha) treatment in patients with chronic hepatitis C virus (HCV) infection is a challenging obstacle for clinical and experimental hepatology. Both viral and host factors have been implicated in reducing responsiveness to IFN-alpha therapy. The role of viral factors has been studied extensively and has been summarized in several review articles; however, much less attention has been paid to host factors. In this paper, we review evidence of host factor involvement in IFN-alpha treatment failure. We discuss possible underlying mechanisms responsible for these effects. Potential therapeutic strategies to enhance the effectiveness of IFN-alpha therapy for HCV are also proposed.

Abstract
The prevalence of hepatitis C is 7-10-fold higher in alcoholics than it is in the general population. Among alcoholics, the prevalence of hepatitis C is higher in alcoholics with advanced liver disease. Serum ALT and hepatitis C viral load may improve if alcoholic patients with hepatitis C stop drinking for more than 4 months.Up to 60% of patients with hepatitis C have a past history of alcohol use. In patients with hepatitis C, chronic alcohol consumption of more than 5 drinks per day increases the rate of liver fibrosis. Hepatitis C patients who ingest more than 5 alcoholic drinks per day are at increased risk for cirrhosis, hepatocellular carcinoma and, possibly, death from liver disease. Recent alcohol use decreases the response rate to interferon treatment. The detrimental effects of small amounts (3 or fewer drinks per day) of alcohol consumption in patients with hepatitis C are not known.

Abstract
BACKGROUND Porphyria cutanea tarda (PCT) is sometimes associated with hepatitis C virus chronic infection. The aim of this study was to describe the effect of interferon alfa (IFN-a) in the treatment of patients with chronic hepatitis C and PCT. METHODS We treated a total of 66 patients with chronic hepatitis C with IFN-a 2b (5 MU t.i.w.) for 12 months. Twenty-two of these patients suffered from PCT as well. These patients differed from patients without PCT in that they were men, past history of alcohol abuse and HFE gene mutations were more common and the source of infection was almost always unknown. RESULTS Sustained virologie response was obtained in 19.7% of the 66 treated patients, 27.3% in the non-PCT group and 4.5% in the PCT group (P < 0.05). This difference could not be ascribed to the difference in sex of patients, history of alcohol abuse, HCV genotype or iron status. CONCLUSION Multivariate logistic regression analysis revealed that PCT is independently and significantly associated with non-sustained response to IFNa therapy. In conclusion, patients with chronic hepatitis C and PCT rarely responded to IFNa treatment.

Abstract
Heavy alcohol consumption has been reported to negatively affect the outcome of interferon therapy. We studied the impact of lifetime alcohol consumption in patients with chronic hepatitis C treated with interferon after 6 months of alcohol withdrawal. Alcohol intake was measured when patients with chronic hepatitis C were referred to us for the first time, and from that moment complete abstinence was recommended. After 6 months of abstinence, 150 patients with persistent elevated serum alanine aminotransferase (ALT) have been treated with interferon (IFN)-alpha, 3 or 6 microU three times per week for 12 months. Univariate and multivariate analysis were performed to identify the predictors of treatment response. Carbohydrate-deficient transferrin was employed to assess alcoholic abstinence. The sustained response rate felt from 33% in nondrinkers to 20% of mild-drinkers and to only 9% in heavy drinkers. Drinker patients showed a relapse rate twice as high as that of nondrinkers. According to the multivariate analysis, the strongest independent predictors of nonresponse were genotype 1b infection, age of the patients and their lifetime alcohol intake. Carbohydrate-deficient transferrin detected at baseline, at 3 months of therapy and at the end of follow-up gave a positive result only in eight determinations (1.77%), confirming the compliance of patients to our recommendation of alcohol abstinence. Lifetime alcohol consumption has a strong negative effect on the outcome of interferon treatment, mainly in heavy drinkers. A 6-month period of abstinence may not be sufficient to offset this negative effect on treatment outcome.

Abstract
Alcohol drinking and viral hepatitis are both recognized as major causes of liver disease worldwide, and they frequently coexist and synergistically cause liver injury in patients with chronic liver disease. Several mechanisms have been implicated in exacerbation of liver injury in patients with alcohol drinking and viral hepatitis. These include impairment of host defense and liver regeneration by alcohol consumption. The findings obtained from my laboratory have demonstrated that alcohol potentiates cooperatively several signals activated by hepatitis B virus X protein (HBX) or hepatitis C virus core protein, and HBX sensitizes hepatocytes to tumor necrosis factor-alpha (TNF-alpha)- and ethanol-induced apoptosis by a caspase-3-dependent mechanism, which may also contribute to the synergistic effect of alcohol drinking and viral hepatitis on liver injury.

Abstract
GOAL To assess the number of chronic hepatitis C patients eligible for therapy. BACKGROUND Recent studies have shown improved response rates to treatment of chronic hepatitis C infection. However, treatment with interferon alfa has major side effects, and many patients may not be eligible for therapy. STUDY One hundred consecutive patients with positive hepatitis C serologies at the Durham Veterans Affairs Medical Center were evaluated. Medical records were reviewed, and the patients were interviewed. Patients were considered ineligible for therapy if they had severe mental illness, hazardous alcohol consumption, current drug abuse, decompensated cirrhosis, dementia, terminal illness, diabetic ketoacidosis, and severe cardiac or pulmonary disease or if they were homeless. RESULTS Of the 100 patients, 92% were male and 51% were African American. The mean age was 47.3 +/- 5.6 years. Only 32 of the 100 patients were eligible for therapy. Hazardous alcohol consumption was present in 44%. Major depressive symptoms were present in 12%. CONCLUSIONS The minority of chronic hepatitis C patients were eligible for therapy. Significant rates of hazardous alcohol consumption and psychiatric disorders were present. For these patients to complete or become eligible for therapy, a multidisciplinary approach with psychiatric and substance abuse treatment will be necessary.

Abstract
BACKGROUND Genotype 1b of hepatitis C virus (HCV) comprises mainly three subtypes, each named for its geographic prevalence (worldwide, W; Japan, J; and not in Japan, NJ). AIM To characterise the newly identified subtypes of genotype 1b and to review factors associated with response to interferon (IFN) for each subtype. PATIENTS Chronic hepatitis patients (80 men and 41 women; mean age 48.5 years, range 20.7--69.3) with HCV genotype 1b (W type, n=41; J type, n=38) or genotype 2a (n=42) were treated according to the same IFN protocol. Forty four patients (36.4%) negative for serum HCV RNA six months after cessation of treatment were considered complete responders. METHODS Factors associated with complete response were investigated. RESULTS Genotype 2a patients had lower viral loads (odds ratio 0.11 (95% confidence intervals (CI) 0.049--0.256)) and a better IFN response (odds ratio 0.25 (95% CI 0.117--0.552)) than genotype 1b patients whereas W type and J type patients had similar viral loads and responses to IFN. IFN response in W type patients was associated with female sex (odds ratio 0.23 (95% CI 0.055--0.983)) and low viral load (odds ratio 84.00 (95% CI 14.04--502.6)) whereas response in J type patients was related to transfusion history (odds ratio 7.20 (95% CI 1.443--35.91)), low viral load (odds ratio 117.0 (95% CI 17.82--768.3)), and genetic mutation in the interferon sensitivity determining region of the virus (odds ratio 0.08 (95% CI 0.013--0.553)). Multivariate analysis found low viral load (odds ratio 64.19 (95% CI 14.66--281.06)) to be the only significant independent factor associated with IFN response. CONCLUSIONS Factors associated with IFN responsiveness in HCV infection differ with viral subtype.

Abstract
OBJECTIVES To understand the molecular mechanism underlying alcoholic liver injury, effects of acute ethanol on the Janus kinase-signal transducer and activator transcription factor (JAK-STAT) signaling in hepatic cells were studied. DESIGNS AND METHODS Effects of acute ethanol on the JAK-STAT signaling in freshly isolated, cultured rat hepatocytes, and HepG2 cells were explored. RESULTS Acute ethanol exposure inhibited IL-6- or IFN-activated STAT in freshly isolated hepatocytes but not in cultured hepatocytes, HepG2 cells, or HepG2 cells transfected with alcohol dehydrogenase (ADH) or cytochrome P450(2E1). The inhibitory action of ethanol in freshly isolated hepatocytes was not antagonized by the ADH inhibitor 4-methylpyrazole (4-MP). Acute exposure of hepatocytes to acetaldehyde or hydrogen peroxide did not suppress STAT activation. Further studies indicated that the loss of response to the inhibitory effect of ethanol was not due to hepatocyte proliferation and collagen contact. CONCLUSIONS Freshly isolated hepatocytes are more susceptible to the inhibitory action of ethanol on the JAK-STAT signaling than cultured hepatocytes or HepG2 cells, which may be implicated in pathogenesis and progression of alcoholic liver disease.

Abstract
Tattooing in commercial tattoo parlors is known to transmit blood-borne viral infections, including hepatitis C virus (HCV), in other countries, but its contribution to the high population prevalence of HCV infection in the United States has been incompletely evaluated. Risk factors for blood-borne infection were assessed by physician's interview of 626 consecutive patients undergoing medical evaluation for spinal problems in 1991 and 1992 while unaware of their HCV status. Later all were screened for HCV infection with enzyme-linked immunosorbent assay (EIA-1 and EIA-2), and positives were confirmed with second-generation recombinant immunoblot assay (RIBA). Forty-three patients were seropositive for HCV (sample prevalence 6.9%, population-standardized prevalence 2.8%). Logistic regression analysis identified 4 independent risk factors for HCV infection: injection-drug use (adjusted prevalence odds ratio [OR] = 23.0; 95% confidence intervals [CI] = 7.5-70.6), ancillary hospital jobs held by men (OR = 9.6; 95% CI = 3.8-24.3), tattoos from commercial tattoo parlors (OR = 6.5; 95% CI = 2.9-14.8), and drinking > or = 3 6-packs of beer per month (OR = 4.0; 95% CI = 1.8-8.7). If causal, these 4 risk factors account for 91% of HCV infections, with tattooing explaining 41%, heavy beer drinking 23%, injection-drug use 17%, and ancillary health care jobs for men 8%. Transfusions, promiscuous sexual activity, bone grafts, acupuncture, perinatal or intimate transmission in families, and other modes were not independently associated with serologic evidence of HCV infection. Unlikely to be explained by confounding or incomplete disclosure of other risk factors, tattooing in commercial tattoo parlors may have been responsible for more HCV infections than injection-drug use.

Abstract
Hepatic changes resulting from the regular ingestion of alcohol are many and include fat infiltration, alcoholic hepatitis, and cirrhosis. Only 10% to 15% of chronic alcoholics develop liver disease. Women are more susceptible. An area of considerable importance is the high prevalence of concomitant infection with hepatitis C virus in chronic alcoholics. Patients who have hepatitis C and alcohol-induced liver injury are much more likely to develop progressive liver disease and cirrhosis. Corticosteroid therapy has proven useful in the treatment of patients with severe acute alcoholic hepatitis.

Abstract
A close relationship and possible interaction has been noted between alcohol intake and hepatitis C virus infection, since the discovery of HCV markers. It is not understood whether these are additive or synergistic effects in causing liver injury. Interactions between alcohol and HCV may be studied at several levels, including epidemiology, virology (including viral load), histology (effect on the severity of liver lesions), carcinogenesis (the role of alcohol in the occurrence of hepatocellular carcinoma), and the effect on the extrahepatic manifestations or severity of HCV infection. At the epidemiological level, a high prevalence of HCV infection was noted in patients with alcoholic liver diseases (14-37%), also characterized by a high rate of viral replication as detected by PCR, which was present in over 90% of patients tested. Moreover, the prevalence of anti-HCV antibodies increased proportionally with the severity of liver lesions. Virological analysis based on the determination of HCV RNA levels in the serum showed variations of HCV RNA levels with diet, and a clear relationship between self reported alcohol consumption and the levels of serum HCV RNA (r = .26, p = .001). At the histologic level the role of alcohol may be evaluated either through the development of fibrosis or by determination of the incidence of cirrhosis. A study on the effect of alcohol intake below or over 40 g per day on the histologic progression of liver lesions has confirmed a more rapid increase in fibrosis and a doubling in the incidence of cirrhosis in patients admitting to alcohol consumption >40 g per day. The role of alcohol in the occurrence of hepatocellular carcinoma in patients with cirrhosis due to HCV infection has been extensively studied with controversial results. A recent case control study performed in Italy showed that the relative risk of HCC in patients with HCV infection and heavy alcohol consumption doubled. Finally, alcohol consumption potentially worsens the evolution of dermatological diseases associated with HCV infection such as porphyria cutanea tarda. All of the above are strong arguments which should be used to advise HCV patients against alcohol consumption, regardless of the degree of liver injury. However, the deleterious effect of the occasional intake of small amounts of alcohol has not been demonstrated and therefore an occasional drink may be allowed in some cases.

Abstract
The role of alcohol intake in the occurrence of severe liver disease in chronic hepatitis C virus (HCV) carriers is still debated. A cross-sectional study has been conducted in 233 chronic hepatitis C virus carriers. Weekly self-reported alcohol consumption (SRAC) was evaluated, serum HCV RNA levels were measured by a branched DNA technique (Quantiplex 2.0) and HCV genotypes were determined. A liver biopsy was performed simultaneously and liver lesions were graded with the Knodell histological activity index. Data were examined by uni- and multivariate analyses. Alcohol consumption was relatively low (< 140 g/per week in 193/233 patients [80%]). We found a highly significant correlation between SRAC and serum HCV RNA levels (r = .26, P = .001). Fibrosis was significantly correlated with age and alcohol consumption. These results suggest that in HCV carriers, alcohol consumption, even with low alcohol intake, increases viremia and hepatic fibrosis. Chronic HCV carriers should be advised to avoid regular alcohol intake.

Abstract
Hepatitis C chronically infects approximately 1.5% of Americans and is the most common clinical problem facing hepatologists. Since the virus was initially described in 1989, development of an effective therapy has been challenging. Although several different therapeutic agents have been used, no therapy has been shown to reliably eradicate the virus. Interferon-alpha, a cytokine with immunostimulatory and anti-viral properties, has become the therapy of choice for patients with chronic hepatitis C infection. Trials assessing the efficacy of interferon-alpha have characterized host and viral factors predictive of responses to treatment. A thorough understanding of these predictive factors is requisite to providing cost-effective therapeutic decisions for the patient with chronic hepatitis C infection.
