Subthreshold mania as predictor of depression during interferon treatment in HCV+ patients without current or lifetime psychiatric disorders

Facing HCV as a Major Public Healthcare Threat in Italy: Epidemiology and Micro-Elimination Pathways among Underserved Populations

Underserved populations have a wide heterogeneity on healthcare provision and use. They also represent the key populations according to WHO 2030 goals for HCV micro-elimination. Our review evaluated the available literature on HCV diagnosis, staging, and treatment among underserved populations, such as incarcerated people, patients with psychiatric disorders, and migrants. A narrative review of literature was performed using key electronic databases (Scopus, Pubmed-MEDLINE) and search engines (Google Scholar). Peer-reviewed publications, grey literature on HCV, and recent models proposed for micro-elimination in underserved populations were included. An insight into the COVID-19 pandemic and its influence on HCV micro-elimination pathways will be also provided. Regarding prison settings, a progressive reduction in HCV epidemiology among incarcerated people in the last years was found (one-third of the level it had been before). People suffering from psychiatric disorders have a high anti-HCV prevalence, but there is a lack of data on active infections. A bidirectional relationship between HCV and psychiatric disorders was found. Migrants showed a very inconsistent assessment of HCV. Furthermore, available studies recorded data from populations with high heterogeneity of anti-HCV prevalence, Therefore, the reported results need caution in their evaluation.

Affective temperament and mood spectrum symptoms in workers suffering from work-related stress disorders

INTRODUCTION

Adjustment Disorders (AD) which develop in response to work-related stressors represent a model of psychiatric occupational disease. Major Depressive Episodes (MDE) although often associated to work-related stressors are unlikely recognized by insurance institutes as occupational diseases. Affective temperament and mood spectrum symptoms are possible factors of vulnerability to stress. The aim of this study was to investigate if temperaments and mood spectrum symptoms had a different distribution among workers exposed to occupational stress and suffering from different psychiatric disorders (AD, MDE).

METHODS

156 AD and 97 MDE patients were recruited and evaluated with scales for perceived stress (PSM) and work-related stress (JCQ), for psychopathological symptoms (BDI-II, SAS), for affective temperament (TEMPS-A[P]) and for lifetime mood spectrum symptoms (MOODS-SR). Group comparisons and correlation analyses between variables were performed by parametric or non-parametric statistical tests according to variables distribution.

RESULTS

The diagnostic groups did not differ for perceived and occupational stress levels. MDE patients reported significantly higher BDI-II score and MOODS-SR scores than AD ones. The hyperthymic temperament was significantly more frequent in AD than in MDE group. The hyperthymic score, differently from other dimensions of temperament and from mood spectrum components, negatively correlated or did not correlate with psychopathological symptoms severity and perceived stress levels.

LIMITATIONS

Predictive limitation because of cross-sectional design.

CONCLUSIONS

The hyperthymic temperament as opposed to lifetime subtreshold mood symptoms appears to be more represented in patients suffering from occupational AD than in MDE ones. Acknowledging vulnerability factors to job stress could support clinicians in occupational diseases prevention and management.

Suicidality and Illness Course Worsening in a Male Patient with Bipolar Disorder during Tamoxifen Treatment for ER+/HER2+ Breast Cancer

PURPOSE

Tamoxifen is a selective estrogenic receptor modulator (SERM) drug. In addition to its common use in breast cancer ER+, Tamoxifen has been object of growing interest in psychiatry as antimanic drug. At the same time, clinical concerns about Tamoxifen's depressogenic effect have been repeatedly raised even without reaching univocal conclusions. We discuss the case of a 45-year-old-male with a diagnosis of Bipolar Disorder type II, treated with Tamoxifen as relapse prevention treatment after surgery for a ER+/HER2+ breast cancer. The patient required two psychiatric admissions in a few-month time span since he showed a progressive worsening of both depressive and anxiety symptoms, with the onset of delusional ideas of hopelessness and failure up to suicidal thoughts. The clinical picture showed poor response to treatment trials based on various associations of mood-stabilising, antidepressants, and antipsychotic drugs. During the second hospitalization, after a multidisciplinary evaluation, the oncologists agreed on Tamoxifen discontinuation upon the severity of the psychiatric condition. The patient underwent a close oncological and psychiatric follow-up during the following 12 months.

METHODS

Psychiatric assessments included the Montgomery-Asberg Depression Rating Scale (MADRS), the Hamilton Depression Scale (HAM-D), the Columbia Suicide Severity Rating Scale (C-SSRS), and the Quality of Life Enjoyment and Satisfaction Questionnaire Short Form (Q-LES-Q-SF). All questionnaires were administered at the time of the second hospitalization and in a one-year follow-up.

RESULTS

Suicidal ideation fully remitted and depressive symptoms markedly and rapidly improved in the aftermath of Tamoxifen discontinuation. The symptomatological improvement remained stable across one-year follow-up.

CONCLUSIONS

Male patients with a mood disorder history constitute a high-risk group as to Tamoxifen psychiatric side effects. The onset or worsening of depressive symptoms or suicidality should be carefully addressed and promptly treated, and clinicians should be encouraged to consider the possibility of discontinue or reduce Tamoxifen therapy after a multidisciplinary evaluation.

Biopsychosocial predictors of interferon-related depression in patients with Hepatitis C

OBJECTIVES

The aim of this study is to examine the role of different bio-psycho-social risk factors for the onset of depression among patients with Hepatitis C (HCV) treated with Interferon alpha (IFN).

MATERIAL AND METHODS

Patients with HCV were recruited and assessed prospectively at baseline and after 4, 8, and 24 weeks since the start of IFN treatment. Assessments included the Hamilton Depression and Anxiety Rating Scales (HAM-D and HAM-A), Toronto Alexithymia Scale, Temperament Evaluation of the Memphis, Pisa, Paris and San Diego, 110 item version (TEMPS-A), Young Mania Rating Scale and other assessment tools. Sociodemographic and clinical factors were entered as predictors in logistic regression models, with early-onset depression (4 weeks) or persistent depression (24 weeks) as the outcomes.

RESULTS

Early-onset depression was predicted by preexisting depressive symptoms' severity (baseline HAM-D scores: OR=1.24; 95% CI: 1.03, 1.50; p=0.03) and by the presence of additional physical comorbidities (OR=3.74; 95% CI: 1.12, 12.5; p=0.03). Persistent depression was predicted by additional physical comorbidities (OR=7.75; 95% CI: 1.33, 45.0, p=0.02), depressive temperament (OR=8.95; 95% CI: 1.32, 60.6; p=0.03) and, at trend-level, by unknown mode of HCV contagion (OR=5.21; 95% CI: 0.89, 30.4; p=0.07).

CONCLUSIONS

The incidence of IFN-related depression is associated with factors related to patients' physical and temperamental characteristics. Further research should include comprehensive biopsychosocial assessments to improve the early detection and treatment of vulnerable patients in the real clinical world.

Interferon α Therapy in Patients with Chronic Hepatitis C Infection: Quality of Life and Depression

Health-related quality of life was examined in 49 patients with hepatitis C virus with no psychiatric history who received interferon (IFN)-α treatment. Quality of life was assessed at baseline, at 3-time points during IFN-α therapy and at 1-6 month follow-up, using SF-36. Hepatitis C virus patients showed poorer physical functioning and better social and mental functioning than a normal population. Significant decreases from baseline SF-36 scores were observed at an early phase of treatment. Six patients developed major depression during IFN-α treatment. At baseline, they had reported more bodily pain than patients who did not develop depression during treatment. Planned contrasts revealed that worsening in some dimensions of quality of life at 2 months was greater in depressed than in non-depressed patients. Results suggest that depressive symptoms should be accurately monitored during IFN-α therapy even in patients with no psychiatric history, especially if they present with bodily pain.

Statin use and risk of depression: a Swedish national cohort study

BACKGROUND

Statin medications, used to prevent heart disease by reducing cholesterol, also reduce inflammation and protect against oxidative damage. As inflammation and oxidative stress occur in depression, there is interest in their potential to reduce depression risk. We investigated whether use of statin medications was associated with a change in the risk of developing depression in a very large Swedish national cohort (n = 4,607,990).

METHODS

National register data for adults ≥40yr was analyzed to obtain information about depression diagnoses and prescriptions of statin medications between 2006 and 2008. Associations were tested using logistic regression.

RESULTS

Use of any statin was shown to reduce the odds of depression by 8% compared to individuals not using statin medications (OR = 0.92, 95% CI, 0.89-0.96; p < 0.001). Simvastatin had a protective effect (OR = 0.93, 95% CI, 0.89-0.97; p = 0.001), whereas atorvastatin was associated with increased risk of depression (OR = 1.11, 95% CI, 1.01-1.22; p = 0.032). There was a stepwise decrease in odds ratio with increasing age (OR ≥ 40 years = 0.95, OR ≥ 50 years = 0.91, OR ≥ 60 years = 0.85, OR ≥ 70 years = 0.81).

CONCLUSIONS

The use of any statin was associated with a reduction in risk of depression in individuals over the age of 40. Clarification of the strength of these protective effects, the clinical relevance of these effects and determination of which statins are most effective is needed.

Reliability and predictive validity of a hepatitis-related symptom inventory in HIV-infected individuals referred for Hepatitis C treatment

Background

We aimed to determine the reliability and validity of a hepatitis symptom inventory and to identify predictors of hepatitis C (HCV) treatment initiation in a cohort of HIV-infected patients.

Methods

Prospective clinic based study that enrolled patients referred for HCV therapy consideration. A hepatitis symptom inventory and the Center for Epidemiologic Studies Depression Scale (CES-D) were administered to HIV/HCV individuals. The symptom inventory was factor analyzed and subscale reliability estimated with Cronbach's alpha. Predictive validity was evaluated using generalized estimating equations (GEE). Predictors of HCV treatment were identified using logistic regression.

Results

Between April 2008 to July 2010, 126 HIV/HCV co-infected patients were enrolled in the study. Factor analysis using data from 126 patients yielded a three-factor structure explaining 60% of the variance for the inventory. Factor 1 (neuropsychiatric symptoms) had 14 items, factor 2 (somatic symptoms) had eleven items, and factor 3 (sleep symptoms) had two items, explaining 28%, 22% and 11% of the variance, respectively. The three factor subscales demonstrated high intrinsic consistency reliability. GEE modeling of the 32 patients who initiated HCV therapy showed that patients developed worsening neuropsychiatric and somatic symptoms following HCV therapy with stable sleep symptoms. Bivariate analyses identified the following as predictors of HCV therapy initiation: lower HIV log₁₀ RNA, lower scores for neuropsychiatric, somatic and sleep symptoms, lower CES-D scores and white ethnicity. In stepwise multiple logistic regression analysis, low neuropsychiatric symptom score was the strongest independent predictor of HCV therapy initiation and HIV log₁₀ RNA was inversely associated with a decision to initiate HCV treatment.

Conclusions

A 41-item hepatitis-related symptom inventory was found to have a clinically meaningful 3-factor structure with excellent internal consistency reliability and predictive validity. In adjusted analysis, low neuropsychiatric symptom scores and controlled HIV infection were independent predictors of HCV treatment initiation. The usefulness of the HCV symptom inventory in monitoring HCV treatment should be evaluated prospectively.

Risk factors for the development of depression in patients with hepatitis C taking interferon-α

Interferon-α, currently used for the treatment of hepatitis C, is associated with a substantially elevated risk of depression. However, not everyone who takes this drug becomes depressed, so it is important to understand what particular factors may make some individuals more 'at risk' of developing depression than others. Currently there is no consensus as to why interferon-induced depression occurs and the range of putative risk factors is wide and diverse. The identification of risk factors prior to treatment may allow identification of patients who will become depressed on interferon, allowing the possibility of improved treatment support and rates of treatment adherence. Here, we consolidate and review the literature on risk factors, and we discuss the potential confounds within the research examined in order to better isolate the risk factors that may be important in the development of depression in these patients and which might help predict patients likely to become depressed on treatment. We suggest that interactions between psychobehavioral, genetic, and biological risk factors are of particular importance in the occurrence of depression in patients with hepatitis C taking interferon-α.

Association of high-sensitivity C-reactive protein with de novo major depression

BACKGROUND

Although there is cross-sectional evidence that changes in the immune system contribute to the pathophysiology of depression, longitudinal data capable of elucidating cause and effect relationships are lacking.

AIMS

We aimed to determine whether subclinical systemic inflammation, as measured by serum high-sensitivity C-reactive protein (hsCRP) concentration, is associated with an increased risk of de novo major depressive disorder.

METHOD

Major depressive disorder was diagnosed using a clinical interview (SCID-I/NP). This is a retrospective cohort study; from a population-based sample of 1494 randomly selected women recruited at baseline during the period 1994-7, 822 were followed for a decade and provided measures of both exposure and outcome. Of these women, 644 (aged 20-84 years) had no prior history of depression at baseline and were eligible for analysis.

RESULTS

During 5827 person-years of follow-up, 48 cases of de novo major depressive disorder were identified. The hazard ratio (HR) for depression increased by 44% for each standard deviation increase in log-transformed hsCRP (ln-hsCRP) (HR = 1.44, 95% CI 1.04-1.99), after adjusting for weight, smoking and use of non-steroidal anti-inflammatory drugs. Further adjustment for other lifestyle factors, medications and comorbidity failed to explain the observed increased risk for depression.

CONCLUSIONS

Serum hsCRP is an independent risk marker for de novo major depressive disorder in women. This supports an aetiological role for inflammatory activity in the pathophysiology of depression.

Protective autoimmunity functions by intracranial immunosurveillance to support the mind: The missing link between health and disease

Circulating immune cells support hippocampal neurogenesis, spatial memory, expression of brain-derived neurotrophic factor, and resilience to stress. Nevertheless, considering the immune privileged status of the central nervous system (CNS), such cells were assumed to be excluded from the healthy brain. It is evident, however, that the CNS is continuously surveyed by leukocytes, though their function is still a mystery. Coupling this routine leukocyte trafficking with the function attributed to circulating T cells in brain plasticity led us to propose here that CNS immunosurveillance is an integral part of the functioning brain. Anatomical restriction of selected self-recognizing leukocytes to the brain's borders and fluids (cerebrospinal fluid) not only supports the brain's activity, but also controls the potential aggressiveness of such cells. Accordingly, the brain's 'privilege' is its acquisition of a private peripheral immunological niche under its own control, which supports brain function. Immune malfunction may comprise a missing link between a healthy and diseased mind.

Psychiatric care of the patient with hepatitis C: a review of the literature

CONTEXT

Approximately 1.8% of the US population is chronically infected with the hepatitis C virus (HCV). The prevalence rates of psychiatric illness in patients with HCV infection are higher than those rates in the general US population, and the prevalence of HCV infection in patients with severe mental illness may be as high as 9 times that of the general US population. Primary care physicians and psychiatrists are on the forefront of identifying patients with psychiatric illness who are at risk for HCV infection and can screen for HCV infection. This review summarizes the psychiatric implications of HCV infection and strategies for the management of interferon alfa-induced neuropsychiatric adverse effects.

EVIDENCE ACQUISITION

English-language studies were identified by computerized searches using the term hepatitis C psychiatric between 1972 and 2009, and further references were obtained from bibliographies of the reviewed articles. Relevant references were reviewed by the authors and included the basis of significance and applicability to practicing psychiatrists and internists.

RESULTS

Since primary care physicians and psychiatrists are sometimes the only medical link for patients with psychiatric illness, they are expected to provide posttest counseling for their patients with HCV and psychiatric illness. The task of conducting a psychiatric and psychosocial pretreatment risk-benefit assessment to determine whether or not to treat HCV infection is increasingly delegated to primary care providers as well as psychiatrists. The use of interferon alfa-based therapies to eradicate HCV has been associated with frequent neuropsychiatric adverse effects (eg, affective, anxiety, cognitive, and psychotic symptoms) that compromise the management of HCV patients with and without a preexisting history of psychiatric illness. Primary care physicians and psychiatrists are frequently asked to assist in the management of these neuropsychiatric adverse effects and evaluate the risks and benefits of using prophylactic psychotropics.

CONCLUSIONS

Despite the clinical challenge that interferon alfa treatment for patients with comorbid HCV and psychiatric illness presents, recent research indicates that interferon alfa can be safely administered to HCV-infected patients with psychiatric disorders provided there is a comprehensive pretreatment assessment, a risk-benefit analysis, and intensive ongoing medical and psychiatric follow-up.

Managing depression during hepatitis C treatment

OBJECTIVE

The prevalence of hepatitis C virus (HCV) infection in Canada is estimated to be 1% and expected to increase during the next decade. Mental illness, particularly depression, is common among HCV-infected patients and remains an obstacle to interferon-alpha (IFN-alpha) treatment. We summarize the risk factors for interferon-alpha-induced major depressive disorder (IFN-alpha-MDD) in HCV patients and the evidence for antidepressant prophylaxis and symptomatic antidepressant treatment of depression.

METHODS

We searched MEDLINE, EMBASE, and CINAHL for randomized controlled or quasi-experimental trials evaluating antidepressant prophylactic and symptomatic treatment approaches for depression emerging during IFN-alpha treatment. Manual searches of references listed in review articles, case series, and anecdotal reports supplemented our literature search.

RESULTS

A total of 9 trials involving prophylactic and symptomatic treatment approaches for IFN-alpha-MDD are summarized in our review. Antidepressant pretreatment is beneficial for patients with elevated baseline depressive symptoms and a preexisting history of IFN-alpha-MDD. Although limited evidence exists for several antidepressant agents, much of the evidence suggests that selective serotonin reuptake inhibitors (SSRIs) are safe and efficacious in treating depressive symptoms secondary to IFN-alpha therapy.

CONCLUSION

Both antidepressant pretreatment and symptomatic treatment are viable strategies for treating IFN-alpha-MDD. Improved treatment outcomes and early identification of depression during HCV treatment can be achieved using an integrated medical and mental health treatment approach.

A multidimensional spectrum approach to post-traumatic stress disorder: comparison between the Structured Clinical Interview for Trauma and Loss Spectrum (SCI-TALS) and the Self-Report instrument (TALS-SR)

Dimensional approaches to psychiatric disorders have shown an increased relevance in the ongoing debate for the forthcoming Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. In line with previously validated instruments for the assessment of different mood, anxiety, eating and psychotic spectra, we tested the validity and reliability of a newly developed Structured Clinical Interview for Trauma and Loss Spectrum (SCI-TALS). The instrument is based on a multidimensional approach to post-traumatic stress spectrum that includes a range of threatening or frightening experiences, as well as a variety of potentially significant losses, to which an individual can be exposed. Furthermore, it explores the spectrum of the peritraumatic reactions and post-traumatic symptoms that may ensue from either type of life events, targeting soft signs and subthreshold conditions, as well as temperamental and personality traits that may constitute risk factors for the development of the disorder. The aim of the present study is to describe the reliability of the self-report version of the SCI-TALS: the TALS-SR. Thirty patients with PTSD and thirty healthy control subjects were assessed with the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition. Half of the patients and controls received the TALS-SR first and the SCI-TALS after 15 days; for the other half of the sample, the order of administration was reversed. Agreement between the self-report and the interview formats was substantial. Intraclass correlation coefficients ranged from 0.934 to 0.994, always exceeding the threshold of 0.90. Our findings provide substantial support for the reliability of the TALS-SR questionnaire.

Psychiatric problems in patients infected with hepatitis C before and during antiviral treatment with interferon-alpha: a review

OBJECTIVE

Neuropsychiatric symptoms are common in patients with chronic hepatitis C (CHC) and can potentially be exacerbated by interferon-alpha treatment. Such symptoms can contribute to problems with treatment adherence, which can significantly compromise epidemiological virus control. This review summarizes current knowledge about the etiology, course, and management of neuropsychiatric symptoms in patients with CHC.

METHOD

Studies were identified using computerized searches, with further references obtained from the bibliographies of the reviewed articles.

RESULTS

Psychopathological syndromes that occur during interferon-alpha treatment frequently have atypical features that may complicate their recognition using standard diagnostic criteria. In addition, prospective studies in this area often exclude patients with psychiatric disorders and have methodological disparities that make it difficult to develop guidelines for management of psychiatric side effects induced by interferon-alpha. Despite the high prevalence of chronic hepatitis C virus (HCV) infection in patients with psychiatric and substance use disorders, neuropsychiatric concerns often lead to the exclusion of such patients from interferon-alpha treatment, inappropriately depriving them of the potential benefits of this therapy.

CONCLUSION

Consultation-liaison psychiatrists should become familiar with the clinical spectrum of presentations associated with HCV infection as well as with related neuropsychiatric symptoms in order to promote the creation of multidisciplinary teams who specialize in the care of patients with HCV infections. More studies are needed to define neuropsychiatric syndromes that can be induced by interferon-alpha and to clarify best assessment and treatment procedures for these syndromes. It is also important to create and evaluate psychoeducational programs for all patients with chronic HCV infections, even those with low risk of complications, in order to promote adherence to therapy and optimize patients' quality of life.

Neuropsychiatric disorders related to interferon and interleukins treatment

Certain cytokines such as interferon-alpha and interleukin-2 are often used in the treatment certain cancers and chronic diseases such as melanoma, hepatitis C infection and multiple sclerosis. Several neuropsychiatric side effects such as depression, anxiety, psychosis, suicidal ideation, hypomanic mood and cognitive impairment were reported in those patients who received those medications. In certain patients with those neuropsychiatric side effects, the symptoms ceased when the medication was stopped. However, in some cases, the cognitive impairment persisted even for years after cessation of the medication. In animal studies, those cytokines could induce sickness behaviour, anxiety behaviour and social anhedonia. The increased in pro-inflammatory cytokines in certain neuropsychiatric disorders was widely reported. In addition, in animal studies, the treatment with interferon-alpha or interleukin-1 could induce depressive like behaviour. Recently, the role of certain pro-inflammatory cytokines that could enhance the activity of the enzyme, indoleamine 2-3, dioxygenase (IDO) which in turn would increase tryptophan degradation into kynurenine and decrease tryptophan availability of tryptophan in the brain to synthesize serotonin, a neurotransmitter which is necessary for the normal mood state became of interest in pathophysiology of psychiatric disorders. Furthermore, the imbalance in the further downward catabolic kynurenine pathway and their interactions with other neurotransmitters has been proposed to play an important role. The presence of such an imbalance in patients being treated with cytokines and in patients with psychiatric disorders and the possible consequence of those changes on the neuroprotective function in the brain are discussed in this review.

Sensitivity to change and predictive validity of the MOODS-SR questionnaire, last-month version

BACKGROUND

Instruments that are intended to measure change over time need to emphasize sensitivity to change as a central property. The aims of this report are to test whether the MOODS-SR, a measure of mood spectrum symptomatology, is sensitive to changes during acute and continuation treatment of depression and whether residual mood spectrum symptoms predict relapse in the subsequent 6 months.

METHODS

The study sample includes 316 patients with nonpsychotic depression participating in the protocol 'Depression: the search for treatment-relevant phenotypes'. Patients were initially randomized to selective serotonin reuptake inhibitors or interpersonal psychotherapy and then treated for 9 months using an algorithm-based protocol. Measures of mood symptomatology included the self-report version of the structured clinical interview for mood spectrum (MOODS-SR), the Quick Inventory for Depressive Symptomatology and the Hamilton Rating Scale for Depression.

RESULTS

Repeated-measures ANOVA indicates that during the acute phase MOODS scores decrease significantly from baseline to weeks 6 and 12. This decrease was significantly different (p < 0.001) between those who remitted and those who did not remit on the depressive, the rhythmicity component and the total score. Nonrelapsing subjects had stable scores across the continuation phase, while among relapsing subjects, a significant increase was found in the depressive component (p < 0.001), the rhythmicity component (p = 0.024) and the total score (p < 0.001), at 2 months, followed by a decrease from 2 to 6 months. Scores on the depressive component at the entry into continuation predicted relapse in the subsequent 6 months.

CONCLUSIONS

Our findings suggest that the MOODS-SR is sensitive to change in depression status and may help the clinician to detect symptoms and signs not considered by established symptom severity scales.

Differences in depressive thoughts between major depressive disorder, IFN-alpha-induced depression, and depressive disorders among cancer patients

OBJECTIVE

The objective of this study is to test the hypothesis that there are differences in the distribution of negative thoughts among major depressive disorders (MDD), depressive disorders among cancer patients, and IFN-alpha-induced depression.

METHODS

Twenty-three patients affected by MDD, 25 cancer patients affected by depressive disorders (20 MDD), and 19 patients affected by IFN-alpha-induced depression satisfying MDD criteria were evaluated using the 17-item Hamilton Depression Rating Scale and the 13-item Beck Depression Inventory.

RESULTS

Sense of guilt was higher among MDD patients (56.5%) and was lower among cancer patients (4%) (P<.0001). Sense of failure, dissatisfaction, and self-dislike were higher among MDD patients than among IFN-alpha patients (P<.0001).

CONCLUSIONS

In our study, patients affected by MDD present a different pattern of symptoms in comparison with patients affected by IFN-alpha-induced depression and depressive disorders. In particular, core depressive thoughts were less frequent in the last two conditions.

Hepatitis infection in the treatment of opioid dependence and abuse

Many new and existing cases of viral hepatitis infections are related to injection drug use. Transmission of these infections can result directly from the use of injection equipment that is contaminated with blood containing the hepatitis B or C virus or through sexual contact with an infected individual. In the latter case, drug use can indirectly contribute to hepatitis transmission through the dis-inhibited at-risk behavior, that is, unprotected sex with an infected partner. Individuals who inject drugs are at-risk for infection from different hepatitis viruses, hepatitis A, B, or C. Those with chronic hepatitis B virus infection also face additional risk should they become co-infected with hepatitis D virus. Protection from the transmission of hepatitis viruses A and B is best achieved by vaccination. For those with a history of or who currently inject drugs, the medical management of viral hepatitis infection comprising screening, testing, counseling and providing care and treatment is evolving. Components of the medical management of hepatitis infection, for persons considering, initiating, or receiving pharmacologic therapy for opioid addiction include: testing for hepatitis B and C infections; education and counseling regarding at-risk behavior and hepatitis transmission, acute and chronic hepatitis infection, liver disease and its care and treatment; vaccination against hepatitis A and B infection; and integrative primary care as part of the comprehensive treatment approach for recovery from opioid abuse and dependence. In addition, participation in a peer support group as part of integrated medical care enhances treatment outcomes. Liver disease is highly prevalent in patient populations seeking recovery from opioid addiction or who are currently receiving pharmacotherapy for opioid addiction. Pharmacotherapy for opioid addiction is not a contraindication to evaluation, care, or treatment of liver disease due to hepatitis virus infection. Successful pharmacotherapy for opioid addiction stabilizes patients and improves patient compliance to care and treatment regimens as well as promotes good patient outcomes. Implementation and integration of effective hepatitis prevention programs, care programs, and treatment regimens in concert with the pharmacological therapy of opioid addiction can reduce the public health burdens of hepatitis and injection drug use.
