Abstract
AbstractBackground.Treatment with low-dose interferon alpha (IFN-α) is often associated with neuropsychiatric side effects. In addition to depression and anxiety, IFN-α associated cognitive impairment significantly affects patient’s mental health and quality of life.Aims of the study.To measure possible effects of low-dose IFN-α on cognitive functioning and its relationship to the development of depression and anxiety.Method.We prospectively followed 38 patients with a chronic hepatitis B or C by neuropsychological tests and psychiatric self-rating scales during 12 weeks of low-dose treatment with IFN-α.Results.Before IFN-α treatment, neuropsychological tests as well as self-ratings in the Beck’s Depression Inventory (BDI), the Hospital Anxiety and Depression Scale (HADS) and the Self-Report Symptom Inventory 90 Items-Revised (SCL-90-R) were within the normal range. Following 12 weeks of treatment with IFN-α resulted in a slight, but significant increase in depression scores. Neuropsychological assessment after 12 weeks of IFN-α treatment showed a significant decrease of the immediate recall in the Auditory-Verbal Learning Test (AVLT) and a significant reduction of words recited in the Controlled Oral Word Association Test (COWA). Cognitive impairment did not significantly correlate with depressive symptoms or anxiety.Conclusion.Our results indicate that even low-dose IFN-α induces cognitive impairment independent from depressive symptoms, which might be related to functional disturbances in the prefrontal cortex and the hippocampus. We suggest close monitoring of cognitive function during IFN-α treatment of chronic hepatitis.

Abstract
Major depressive disorder (MDD) often occurs during pegylated IFN-alpha2 (IFN-alpha) treatment. Identifying who is at risk for MDD in this population is essential, and epidemiological studies suggest that sleep may be related to depression risk. Controlling for pre-existing depression symptoms, we therefore examined whether sleep quality prior to IFN-alpha treatment would predict subsequent MDD incidence during IFN-alpha treatment. Adults with hepatitis C but without current clinical MDD (n=86) were evaluated prior to IFN-alpha treatment and then prospectively monitored during treatment using self-report measures of sleep quality (PSQI), depression (BDI), and anger and irritability (AIAQ), as well as with Structured Clinical Interviews for DSM-IV Axis I Disorders (SCID-I). During IFN-alpha treatment, 19% developed MDD, 19% developed subsyndromal depression with irritability, and one developed mania. Controlling for baseline depression symptoms and past history of depression, patients with worse sleep quality (PSQI > or = 10) prior to treatment had a significantly shorter time until they developed MDD or any severe psychiatric problem. These findings may have important implications for understanding, predicting, and possibly preventing depression, particularly in individuals treated with IFN-alpha.

Abstract
Hepatitis C is a global epidemic, and its costs in both lives and health care expenditures continue to rise. The only approved treatment for this disease, interferon-alpha (IFN), causes treatment-emergent depression in more than one quarter of all patients who take it. Newer preparations of IFN have been developed to increase its antiviral efficacy, but the incidence of treatment-emergent depression has not decreased. The data on the epidemiology and risk factors for interferon-induced depression are reviewed in an effort to delineate its standing as a unique psychiatric disorder. In addition, evidence-based treatment approaches are outlined, including the potential efficacy of preinterferon prophylactic treatment with antidepressants.

Abstract
In recent years, research on interferon (IFN)-induced depressive symptoms in antivirally treated patients suffering from chronic hepatitis C (CHC) has considerably intensified. Profound scientific knowledge of this complication is of great relevance with regard to adherence, compliance, and premature therapy discontinuation. Presently, there is considerable variability of both, the frequency and extent of IFN-induced depression reported in different cohorts of patients. The aim of the presented study was to systematically review recent literature of research within this field; and particularly (1) to identify to what extent methodological bias contributed to inconsistent results in different studies, (2) to critically appraise methods and results of studies published so far, and (3) to suggest directions for future work, especially with respect to alternative and improved methodological approaches. The results of this critical review suggest that the variability of findings seem to be largely due to different study populations, treatment regimens, methodological approaches, and sometimes arbitrary or at least poorly defined choice of screening instruments for depression, particularly criteria for clinically relevant depression (cut-off criteria). Study designs and methodological approaches to investigate IFN-alfa-induced depression in patients with CHC have been incoherent. Future research in this field needs agreement on the use of standardized assessment of IFN-induced depression in CHC. Furthermore, objective criteria and guidelines for the treatment of IFN-induced depression in these patients are needed in clinical practice.

Abstract
Over 4 million people in the United States are chronically infected with hepatitis C virus (HCV), and, if untreated, over 20% of these will progress to more serious disease. Persons with severe mental illness (SMI) have markedly elevated rates of HCV infection, but treatment of persons with SMI and HCV has been controversial. Effective antiviral treatment is available, but side effects include depression and other neuropsychiatric symptoms. This article reviews the available data on neuropsychiatric side effects of interferon (IFN) treatment, discusses the limitations of the current research, and makes recommendations regarding HCV treatment in persons with SMI.

Abstract
UNLABELLED Imputability of thymic disorders caused by IFNalpha during the chronic Hepatitis C treatment -- hepatitis C and depression -- the infection by the hepatitis C virus (HCV) is a major public health concern since it affects 1.2% in the French population. Eighty percent of those contaminated by HCV keep bearing the virus chronically although they remain asymptomatic during many years. HCV infection is associated with psychiatric symptoms like depression. Together with other factors (eg the severity of hepatic condition), depression may induce significant impairment in quality of life. Conversely, some psychiatric conditions may increase the risk of HCV infection. In drug-addicted subjects using intravenous route, HCV contamination rate ranges from 74 to 100%. Compared with general population, a higher HCV contamination rate has also been noticed in some other subgroups of subjects (patients with alcohol abuse or dependence, with alcohol-induced hepatic disease and psychiatric inpatients). However, no valid explanation to this phenomenon has been established. Interferon alpha and depression - Interferons are a variety of cytokines naturally produced by human tissues and have also been synthesized for therapeutic purposes (treatment of a variety of cancers and viral infections). Many psychobehavioural symptoms are observed under IFNalpha treatment. Among them, mood disorders are known to occur early after entry into treatment and to be within the reach of preventive measures. The reported frequency of depression during IFNalpha treatment ranges from 0 to 37%. This variation reflects either methodological biases (eg differences in psychiatric assessment) or the heterogeneity of the population of patients accepted in therapeutic protocols. Note that the adjunction of ribavirine to IFNalpha in therapeutic protocols has not brought any changes in the depression frequency. The causal relationship between IFNalpha administration and the occurrence of mood disorders has been tackled by various recent research works focusing on the importance of the immune system in the pathophysiology of depression. Miscellaneous pathophysiological hypotheses -- nature of the psychobehavioural symptomatology -- in addition to depressive symptoms, IFNalpha treatment also induces various cognitive impairments and disruptions in EEG patterns. These symptoms are consistent with a mild subcortical dementia. Data resulting from pharmacological trials in humans and in animals are controversial (eg IFNalpha-induced symptoms being alleviated by both immune and antidepressant therapies). However, the debate about the nature of the psychobehavioural disorders observed under IFNalpha treatment might be no longer relevant in the light of recent theories which regard depression as a maladaptive response to a particular form of stress, namely a deep and diffuse feeling of sickness ("malaise"). These theoretical views ascribe the production of depressive symptoms to a disruption in the immune function, mediated by the variety of cytokines. The therapeutic effects of anti-depressive drugs are thus attributed to their analgesic properties, reducing the "malaise" feeling underlying depressive symptoms. Necessity of a second messanger -- accordingly to current pathophysiological theories, depression results from disorders of various CNS functions, mainly limbic, monaminergic and neuroendocrinal systems. Though, exogenous IFNalpha does not cross the blood-brain barrier when unscathed and an intermediary mechanism is necessary. First to be addressed is the cytokines system itself since it is composed of numerous different molecules interacting in an infinite number of possible combinations. Some of these cytokines (eg some interleukins) both are activated by IFNalpha and can reach CNS; they are good candidates for the role of second messenger mediating the induction of psychobehavioural disorders. Second, keeping in mind that serotonin is a monoaminergic neurotransmitter classically involved in depression pathophysiology, other works have demonstrated that IFNalpha modulates the peripheral activity of indolamine-dioxygenase -- a regulating enzyme of serotonin metabolism -- possibly through lymphocyte T CD4 activation. Third, other authors have postulated an immune-induced vagal mechanism to explain depression caused by IFNalpha. Action of IFNalpha on the neuroendocrine and on neuromodulating functions: monoaminergic hypothesis -- cytokines could have an influence on the mood through their modulating role on the serotoninergic system. IFNalpha treatment is reported to produce: 1) a decrease in tryptophan availability for serotonin synthesis, 2) a decrease in the 5-HIAA level in the LCR, and 3) a modification of the central serotoninergic receptors. Moreover, selective inhibitors of serotonin transporters are effective to treat or prevent depression caused by IFNalpha. Many studies support the serotonin-transporter hypothesis: in vitro, both IFNalpha and interleukine 4 (IL-4) increases the expression of serotonin transporter gene, IFNalpha increases in the production of IL-4 by mononucleus cells (not found in vivo). Serotoninergic system can also be altered by a peripheral action of IFNalpha on trytophan catabolism by activating a concurrent pathway (known as "kynurenine pathway") to serotonin synthesis. Finally, serotonin-mediated vulnerability to the psychobehavioural effects of IFNalpha could be underlain by a polymorphism of serotonin transporter gene. Concerning the other monoaminergic systems, IFNalpha seems to have an amphetamine-like effect at its first administration, followed by a decrease in dopaminergic tone with chronic administration. Dopaminergic depletion, subsequent to psychostimulant abuse for instance, results in severe depressive syndromes. Interactions between IFNalpha and noradrenergic system have also been reported. Neuroendocrinian hypothesis -- when administered through central or peripheral way, IFNalpha simulates/inhibits the corticotrope axis and alters endorphin system as shown by the induction of analgesia, catatonia and behavioural slowdown that can be suppressed by opioid antagonists. IFNalpha neurotoxic effects are successfully treated by naltrexone. Lastly, IFNalpha is known to cause disorders in thyroid function that are likely to contribute to the production or aggravation of mood disorders. CONCLUSION A better understanding of pathophysiologic mechanisms underlying psychiatric side-effects of IFNalpha is essential to extend access to treatment to some categories of patients that remain excluded from the protocols. A better management of those psychiatric side effects should help the clinician not to draw aside patients at risk, ie patients with depression, drug and alcohol addiction. Treating them in a pragmatic and careful way is a major issue, since this population represents a high percentage of the potential candidates for interferon therapy.

Abstract
BACKGROUND Interferon-induced depression ranges from 0 to 50%. Interferon schedule and a history of psychiatric illnesses are not enough to predict who will develop symptoms and who will not. AIMS To assess the prevalence of depression during interferon therapy; to test whether Minnesota Multiphasic Personality Inventory is useful in clinical practice for the early identification of patients at risk of depression; whether and how the depression can be cured. PATIENTS One hundred and eighty-five patients treated with interferon and ribavirin for chronic hepatitis C. METHODS Before therapy, all patients underwent a Minnesota Multiphasic Personality Inventory and a clinical examination, specifically for the identification of depressive symptoms. RESULTS Thirty-one patients developed a psychiatric disorder, 11 of them requiring treatment with anti-depressant drugs. Among the 18 patients with Minnesota Multiphasic Personality Inventory positive tests, 16 developed a psychiatric disorder, 8 of them a severe disorder (sensitivity of 0.58; 0.73 for severe disorders). Among the 154 who did not develop psychiatric side effects, 152 had a negative Minnesota Multiphasic Personality Inventory (specificity: 0.99). Severe psychiatric disorders were successfully treated with anti-depressant drugs. CONCLUSIONS Psychiatric side effects are easy to see during interferon therapy. A psychiatric evaluation should be considered on all patients before treatment. If depression develops, it should be treated aggressively, and selective serotonin re-uptake inhibitors are the anti-depressants of choice.

Abstract
OBJECTIVE The objective of this study is to identify early patients who are at-risk for major depression (MD) induced by interferon-alpha (IFN-alpha) and evaluate the response of depressive symptoms to antidepressants. METHODS Thirty-six consecutive patients were treated with IFN-alpha. Psychiatric evaluations were performed prior to, and at 1 and 2 months after onset of therapy and upon completion of the study. Diagnoses were made according to DSM-IV criteria, and the severity of depressive symptoms was determined by the Hamilton Depression Rating Scale score (HDRSS). RESULTS Of the 36 patients studied, 7 (19%) had MD before IFN-alpha treatment, 6 of which manifested a worsening of the depressive symptomatology during treatment. Of the remaining 29 patients, 9 (31%) developed MD during treatment. The median time required for the appearance or worsening of the depressive symptoms was 15 days (range 7-25). The median HDRSS before IFN-alpha in the 36 patients was 3 (range 1-20), whereas after 1 month of therapy, it was 10 (range 1-24; P=.000004). There was a strong positive correlation in the HDRSS before and 1 month after the initiation of treatment (r=.863). Of the 14 patients with a HDRSS of 1-2 before IFN-alpha treatment, only 1 (7%) developed MD, whereas of the 15 patients with a score >3, 8 (53%) developed MD. Antidepressants resulted in a decrease of the HDRSS to the IFN-alpha pretreatment values. CONCLUSION One third of those treated with IFN-alpha developed MD. The HDRSS before treatment reveals the high- and low-risk patients for developing MD. Psychiatric evaluation should be performed prior to IFN-alpha treatment.

Abstract
Nearly 4 million people in the United States have evidence of hepatitis C infection (HCV), representing a significant cause of cirrhosis and liver cancer as well a major burden to our healthcare systems and society. Antiviral therapy can successfully eradicate HCV over the long term, potentially reducing the risk of progression and improving patients' quality of life. The currently preferred HCV treatment is a combination of pegylated interferon alfa and ribavirin, which can achieve an overall sustained viral eradication rate of 55%. The duration of this treatment is typically determined by HCV genotype and the patient's early virologic response to the antiviral regimen. Evidence has accumulated over the past few years to indicate that close adherence to the optimal antiviral regimen can enhance sustained virologic response. But optimal treatment outcomes require diligence and careful management of side effects related to combination therapy. Although reducing the dose of pegylated interferon alfa, ribavirin, or both can effectively treat side effects, suboptimal doses of this regimen, especially ribavirin, may negatively affect virologic response. An alternative strategy is to use growth factors to treat cytopenias. This strategy can obviate dose reductions while potentially improving patients' quality of life. Patient support seems especially important early after the initiation of antiviral therapy. Encouraging study findings involving the growth factors, epoetin alfa and darbepoetin alfa, suggest improved anemia and quality of life while maintaining the optimal ribavirin dose. Future work should be aimed at providing stronger evidence for the use of these "supportive products" during anti-HCV therapy. As we strive to develop better treatment options for our HCV patients, the importance of adhering to the treatment regimen continues to play a central role. Effective side effect management is crucial for the success of this treatment because adherence is negatively affected by side effects related to the antiviral regimen. By identifying and addressing the important side effects of combination therapy for HCV, adherence to treatment can be improved and optimal outcomes can be achieved.

Abstract
Interferon (IFN)-alpha, IFN-beta, and IFN-gamma are currently available for the treatment of malignancies, viral infections (e.g., hepatitis C virus), multiple sclerosis (MS), and skin conditions. In addition to their therapeutic effects, IFNs commonly cause various side effects. Most common among the side effects of IFN are "flu-like" symptoms such as chills, fever, and muscle soreness. However, IFN can also cause significant neuropsychiatric side effects, particularly symptoms of depression. A literature search was conducted in order to summarize current information on (1) the frequency, characteristics, and risk factors of IFN-induced depression, (2) possible biochemical mechanisms associated with IFN-induced depression, and (3) the treatment strategies for IFN-induced depression. Review of the literature suggests that symptoms of depression induced by IFN therapy, in particular IFN-alpha therapy, are common and can limit the treatment utility, often necessitating discontinuation of IFN therapy or the use of psychopharmacologic agents. Depression is also a suspected side effect of therapy with IFN-beta and IFN-gamma; however, the association has not been as convincingly confirmed. Importantly, IFNs affect neurochemical pathways putatively involved in the etiology of depression. While these depressive side effects usually resolve after the completion of IFN therapy, they can persist or reappear with dose escalations. It is recommended that health care providers, patients and their families be informed about the potential risk of the psychiatric disturbances that can occur with IFN-alpha therapy. Screening and monitoring, ideally using symptom rating scales for depression, and early antidepressant treatment intervention appear necessary to optimize IFN therapy for the majority of patients.

Abstract
BACKGROUND/AIMS We assessed the usefulness of the Cornell Medical Index (CMI) and electroencephalogram (EEG) in the prediction and early detection of psychoneurological symptoms associated with interferon (IFN) therapy for chronic viral hepatitis. METHODS Forty-eight consecutive patients received IFN for chronic viral hepatitis for 8-24 weeks. CMI was measured before IFN therapy. Serial EEGs were recorded before IFN therapy, 2, 4 weeks, and thereafter every 4 weeks in the therapy. RESULTS Psychoneurological symptoms including insomnia, depression, and restlessness were seen in 11 (23%) of 48 patients. Five (13%) of 40 patients with CMI I and II and six (75%) of eight with CMI III developed psychoneurological symptoms (P<0.001). Sensitivity, specificity, and predictive accuracy of CMI III were 55%, 95%, and 75%, respectively. Abnormal EEG such as slow basic rhythm, appeared in 13 patients (27%) during IFN therapy. Psychoneurological symptoms were seen in six (46%) of the 13 patients with abnormal EEG, and in five (14%) of 35 in whom EEG remained normal (P<0.05). CONCLUSIONS CMI is useful for the prediction of IFN-induced psychoneurological symptoms in patients with chronic viral hepatitis. Serial EEGs contribute to the screening and auxiliarily assessing the adverse effects of IFN on the central nervous system.

Abstract
The prevalence of depression is high among injection drug users (IDUs) and among those infected with the hepatitis C virus (HCV). Moreover, one of the drugs used in the standard treatment for HCV infection (interferon) has been known to exacerbate underlying psychiatric disorders such as depression and has been associated with the development of major depressive disorder among HCV-infected patients. For these reasons, the most recent National Institutes of Health consensus statement on the management of HCV infection recommends the identification and treatment of depression prior to the start of HCV treatment. This study aimed to examine the extent of current moderate/severe depressive symptoms in a cohort of HCV-infected IDUs as measured by two screening tools, the Center for Epidemiologic Studies Depression Scale (CES-D) and the Beck Depression Inventory (BDI). Subjects were participants in a multisite behavioral intervention trial among HCV-seropositive, human immunodeficiency virus-negative IDUs aged 18-35 years; the trial was designed to prevent secondary transmission of HCV and to enhance uptake of HCV treatment. Baseline data on demographics, risk behaviors, depression, alcohol use, and health care utilization were measured via audio computer-assisted self-interview. A factor analysis was conducted on each scale to examine the clustering of items used in each to measure depressive symptoms. Baseline depressive symptoms, as measured via the CES-D and the BDI, were also compared using Pearson's correlation coefficient. Of 193 HCV-infected individuals enrolled to date, 75.6% were male, and 65.3% were white. Median age was 25.8 years. Factor analyses revealed that these scales measured depression differently; a distinct somatic component was present in the BDI, but not the CES-D. Using cutoff scores of 23 for the CES-D and 19 for the BDI, 44.0% and 41.5% of the participants were identified as having moderate/severe depressive symptoms, respectively. Over half (56.0%) were identified as having depressive symptoms by either scale. However, there was only moderate agreement between the two scales (kappa=0.46). Depressive symptoms were highly prevalent in this cohort of HCV-infected IDUs. Results indicated that both scales should be used in tandem to have the most sensitive detection of depressive symptoms, thereby maximizing the potential for HCV treatment success.

Abstract
AIM Immunotherapy with interferon-alfa (IFN-alfa) is used in a variety of diseases in- and outside clinical trials (e.g., chronic hepatitis, melanoma, chronic myelogenous leukemia, renal cell carcinoma, multiple myeloma). Treatment with IFN-alfa can cause (severe) neuropsychiatric side effects. The purpose of this article is to give an updated review of data on the incidence, manifestations and prediction of psychiatric side effects of immunotherapy with IFN-alfa. Furthermore, the article gives an overview of the management strategies and of the various theories on the pathophysiology of behavioural effects induced by cytokines. METHODS Use was made of computerized searches and of checking cross-references of articles and book chapters. The data on the incidence, manifestations and prediction are arranged by source of information, by target symptoms and by method of ascertainment. RESULTS Different sources of information exist, e.g. adverse event reports of clinical trials, case descriptions and research specifically targeted on neuropsychiatric side effects. IFN-alfa is capable of inducing depressive symptoms and syndromes; the evidence for the induction of other psychiatric side effects is weaker. The depressive syndromes induced by IFN-alfa are in need of a more precise characterization. The results of studies on prediction of side effects are contradictory. Guidelines on managing psychiatric side effects predominantly arise from practical experience and common sense. Patient education plays a pivotal role. At this moment, there is no comprehensive theory on the pathophysiology of cytokine-induced psychiatric side effects. CONCLUSION There is sufficient empirical support for a causal relation between IFN-alfa and the development of depressive symptoms and syndromes. Practical management of neuropsychiatric side effects begins before the start of therapy and should consist of repeated patient education, drug treatment and supportive measures. There are diverging theories on the pathophysiological backgrounds.

Abstract
Interferon and ribavirin combination therapy for chronic hepatitis C produces a number of well-described side effects that are dominated by fatigue, influenza-like symptoms, hematologic abnormalities, and neuropsychiatric symptoms. Combination therapy with pegylated interferons (peginterferon alfa-2a and alfa-2b) yields an adverse event profile similar to standard interferon, although the frequency of certain adverse events may vary by preparation. Premature withdrawal from therapy due to adverse events was required in 10% to 14% of participants in registration trials of these agents. Most adverse events were safely and effectively managed by dose reduction using predetermined criteria. The most common indications for dose reduction were hematologic abnormalities, such as anemia and neutropenia, with the latter more frequent in peginterferon treatment arms. Recent data suggest that maintaining adherence to a prescribed treatment regimen can enhance antiviral response. Strategies to maximize adherence are being developed and, in the future, may include early identification of and therapy for depression and the selective use of hematopoietic growth factors to ameliorate hematologic abnormalities.

Abstract
OBJECTIVES This meta-analysis was conducted to examine the effectiveness of Chinese herbal medicine (either alone or with interferon alfa) in treating chronic hepatitis B. METHODS We searched the TCMLARS, AMED, CISCOM, EMBASE, MEDLINE, and Cochrane Collaboration databases and then hand-searched the articles' bibliographies. RESULTS Chinese herbal medicine significantly increased seroreversion of HBsAg and was equivalent to interferon alfa in seroreversion of HBeAg and hepatitis B virus (HBV) DNA; Chinese herbal medicine combined with interferon alfa significantly increased seroreversion of HBsAg, HBeAg, and HBV DNA. The Chinese herbal medicine active component bufotoxin combined with interferon alfa significantly increased HBeAg and HBV DNA seroreversion. The Chinese herbal medicine active component kurorinone was equivalent to interferon alfa in seroreversion of HBeAg and HBV DNA. CONCLUSIONS Although the quality of existing studies was poor, these data suggest that further trials of Chinese Herbal Medicine and interferon in chronic hepatitis B infection are justified.

Abstract
The aim of the study was to describe the use of the Brief Symptom Inventory in characterizing the type and severity of emotional distress in 26 patients with chronic hepatitis C who were receiving interferon-alpha-2B and ribavirin. The 6-month actuarial incidence of neuropsychiatric toxicity, determined by physician interview, was 58%. Significant differences in mean depression, anxiety, and somatization Brief Symptom Inventory T scores were noted in the 15 patients with clinically apparent neuropsychiatric toxicity compared to the 11 patients without neuropsychiatric toxicity. Because of its brevity and simplicity, the Brief Symptom Inventory may prove to be a useful adjunct to clinician assessment in detecting and monitoring emotional distress during interferon-alpha treatment of chronic hepatitis C.

Abstract
BACKGROUND/AIMS The aim of our study was to determine the prevalence, type, and severity of emotional distress in a large group of consecutive chronic hepatitis C (CHC) patients not receiving anti-viral therapy. METHODS The brief symptom inventory and a 67-item questionnaire with the SF-36 embedded within it were used to study 220 outpatients with compensated CHC. RESULTS Seventy-seven (35%) participants reported significantly elevated global severity index (GSI) T-scores compared to an expected frequency of 10% in population controls. In addition, significantly elevated depression, anxiety, somatization, psychoticism, and obsessive-compulsive subscale T-scores were reported in 28-40% of subjects. Subjects with an active psychiatric co-morbidity had significantly higher GSI and subscale T-scores compared to subjects with active medical co-morbidities and subjects without medical or psychiatric co-morbidities (P<0.01). However, patients with CHC alone also had a higher frequency of elevated GSI T-scores compared to population controls (20 versus 10%). GSI and subscale T-scores were strongly associated with SF-36 summary scores (P<0.001). CONCLUSIONS Clinically significant emotional distress was reported in 35% of CHC patients not receiving antiviral therapy. In addition to depression, a broad array of psychological symptoms were observed. Further investigation into the etiopathogenesis and treatment of emotional distress in CHC patients is warranted.
