Hepatitis C in schizophrenia: screening experience in a community-dwelling clozapine cohort

Sexually transmitted infections, sexual life and risk behaviours of people living with schizophrenia: systematic review and meta-analysis

BACKGROUND

Sexually transmitted infections (STIs), along with sexual health and behaviour, have received little attention in schizophrenia patients.

AIMS

To systematically review and meta-analytically characterise the prevalence of STIs and sexual risk behaviours among schizophrenia patients.

METHOD

Web of Science, PubMed, BIOSIS, KCI-Korean Journal Database, MEDLINE, Russian Science Citation Index, SciELO and Cochrane Central Register were systematically searched from inception to 6 July 2023. Studies reporting on the prevalence or odds ratio of any STI or any outcome related to sexual risk behaviours among schizophrenia samples were included. PRISMA/MOOSE-compliant (CRD42023443602) random-effects meta-analyses were used for the selected outcomes. Q-statistics, I2 index, sensitivity analyses and meta-regressions were used. Study quality and publication bias were assessed.

RESULTS

Forty-eight studies (N = 2 459 456) reporting on STI prevalence (including 15 allowing for calculation of an odds ratio) and 33 studies (N = 4255) reporting on sexual risk behaviours were included. Schizophrenia samples showed a high prevalence of STIs and higher risks of HIV (odds ratio = 2.11; 95% CI 1.23-3.63), hepatitis C virus (HCV, odds ratio = 4.54; 95% CI 2.15-961) and hepatitis B virus (HBV; odds ratio = 2.42; 95% CI 1.95-3.01) infections than healthy controls. HIV prevalence was higher in Africa compared with other continents and in in-patient (rather than out-patient) settings. Finally, 37.7% (95% CI 31.5-44.4%) of patients were sexually active; 35.0% (95% CI 6.6-59.3%) reported consistent condom use, and 55.3% (95% CI 25.0-82.4%) maintained unprotected sexual relationships.

CONCLUSIONS

Schizophrenia patients have high prevalence of STIs, with several-fold increased risks of HIV, HBV and HCV infection compared with the general population. Sexual health must be considered as an integral component of care.

Patients with severe mental illness and hepatitis C virus infection benefit from new pangenotypic direct-acting antivirals: Results of a literature review

INTRODUCTION

Hepatitis C virus (HCV) infection is a global health problem that can results in cirrhosis, hepatocellular carcinoma and even death. HCV infection is 3-20-fold more prevalent among patients with versus without severe mental illness (SMI), such as major depressive disorder, personality disorder, bipolar disorder and schizophrenia. Treatment options for HCV were formerly based on pegylated interferon alpha, which is associated with neuropsychiatric adverse events, and this contributed to the exclusion of patients with SMI from HCV treatment, elimination programmes, and clinical trials. Moreover, the assumption of poor adherence, scant access to healthcare and the stigma and vulnerability of this population emerged as barriers and contributed to the low rates of treatment and efficacy.

METHODS

This paper reviews the literature published between December 2010 and December 2020 exploring the epidemiology of HCV in patients with SMI, and vice versa, the effect of HCV infection, barriers to the management of illness in these patients, and benefits of new therapeutic options with pangenotypic direct antiviral agents (DAAs).

RESULTS

The approval of DAAs has changed the paradigm of HCV infection treatment. DAAs have proven to be an equally efficacious and safe option that improves quality of life (QoL) in patients SMI.

CONCLUSIONS

Knowledge of the consequences of the HCV infection and the benefits of treatment with new pangenotypic DAAs among psychiatrists can increase screening, referral and treatment of HCV infection in patients with SMI.

Gastrointestinal and liver disease in patients with schizophrenia: A narrative review

Schizophrenia is a severe mental illness which can have a devastating impact on an individual’s quality of life. Comorbidities are high amongst patients and life expectancy is approximately 15 years less than the general population. Despite the well-known increased mortality, little is known about the impact of gastrointestinal and liver disease on patients with schizophrenia. We aimed to review the literature and to make recommendations regarding future care. Literature searches were performed on PubMed to identify studies related to gastrointestinal and liver disease in patients with schizophrenia. High rates of chronic liver disease were reported, with Non-Alcoholic Fatty Liver Disease being of particular concern; antipsychotics and metabolic syndrome were contributing factors. Rates of acute liver failure were low but have been associated with antipsychotic use and paracetamol overdose. Coeliac disease has historically been linked to schizophrenia; however, recent research suggests that a causal link is yet to be proven. Evidence is emerging regarding the relationships between schizophrenia and peptic ulcer disease, inflammatory bowel disease and irritable bowel syndrome; clinical vigilance regarding these conditions should be high. Patients with schizophrenia poorly engage with bowel cancer screening programmes, leading to late diagnosis and increased mortality. Clozapine induced constipation is a significant issue for many patients and requires close monitoring. There is a significant burden of gastrointestinal and liver disease amongst patients with schizophrenia. Better levels of support from all members of the medical team are essential to ensure that appropriate, timely care is provided.

Hepatitis C-associated late-onset schizophrenia: a nationwide, population-based cohort study

BACKGROUND

Whether infection with the hepatitis C virus (HCV) causes schizophrenia - and whether the associated risk reverses after anti-HCV therapy - is unknown; we aimed to investigate these topics.

METHODS

We conducted a nationwide, population-based cohort study using the Taiwan National Health Insurance Research Database (TNHIRD). A diagnosis of schizophrenia was based on criteria from the International Classification of Diseases, 9th revision (295.xx).

RESULTS

From 2003 to 2012, from a total population of 19 298 735, we enrolled 3 propensity-score-matched cohorts (1:2:2): HCV-treated (8931 HCV-infected patients who had received interferon-based therapy for ≥ 6 months); HCV-untreated (17 862); and HCV-uninfected (17 862) from the TNHIRD. Of the total sample (44 655), 82.81% (36 980) were 40 years of age or older. Of the 3 cohorts, the HCV-untreated group had the highest 9-year cumulative incidence of schizophrenia (0.870%, 95% confidence interval [CI] 0.556%-1.311%; p < 0.001); the HCV-treated (0.251%, 95% CI 0.091%-0.599%) and HCV-uninfected (0.118%, 95% CI 0.062%-0.213%) cohorts showed similar cumulative incidence of schizophrenia (p = 0.33). Multivariate Cox analyses showed that HCV positivity (hazard ratio [HR] 3.469, 95% CI 2.168-5.551) was independently associated with the development of schizophrenia. The HCV-untreated cohort also had the highest cumulative incidence of overall mortality (20.799%, 95% CI 18.739%-22.936%; p < 0.001); the HCV-treated (12.518%, 95% CI 8.707%-17.052%) and HCV uninfected (6.707%, 95% CI 5.533%-8.026%) cohorts showed similar cumulative incidence of mortality (p = 0.12).

LIMITATIONS

We were unable to determine the precise mechanism of the increased risk of schizophrenia in patients with HCV infection.

CONCLUSION

In a population-based cohort (most aged ≥ 40 years), HCV positivity was a potential risk factor for the development of schizophrenia; the HCV-associated risk of schizophrenia might be reversed by interferon-based antiviral therapy.

Prevalence of hepatitis C in patients with non-affective psychotic disorders

INTRODUCTION

the goal of this study was to determine the prevalence of hepatitis C virus (HCV) infection in patients with non-affective psychotic disorders and to compare it with population-based data.

MATERIAL AND METHODS

an observational study was performed that measured anti-HCV antibodies (HCV-RNA in case of seropositivity) in 425 serum samples from patients with non-affective psychosis. Eight patients were positive for anti-HCV (1.9 %) and five had detectable HCV-RNA (1.2 %). The prevalence of viremia was significantly higher than in the general population (OR: 5.4; 95 % CI: 1.9-14.6).

CONCLUSIONS

patients with non-affective psychotic disorder have a higher prevalence of active infection than that of the general population and should undergo systematic screening.

Hepatitis C virus and hepatitis B virus in patients with schizophrenia

This study evaluated the severe hepatic outcome (SHO) in patients with schizophrenia and viral hepatitis who received antipsychotics.Using the nationwide Taiwan National Health Insurance Research Database, patients first diagnosed with schizophrenia between 2002 and 2013 were identified. Patients diagnosed with schizophrenia who had viral hepatitis, including hepatitis B virus (HBV) or hepatitis C virus (HCV), were designated as the viral hepatitis group. A control group without viral hepatitis was matched for age, sex, and index year in a 2:1 ratio. Patients with severe hepatic outcomes before enrollment were excluded. The 2 cohorts were observed until December 31, 2013. The primary endpoint was occurrence of a SHO, including liver cancer, liver failure, liver decompensation, or transplantation.Among the 16,365 patients newly diagnosed with schizophrenia between January 2002 and December 2013, we identified 614 patients with viral hepatitis and 1228 matched patients without viral hepatitis. Of these 1842 patients, 41 (2.22%) developed SHOs, including 26 (4.23%) in the viral hepatitis group and 15 (1.22%) in the control group, during the mean follow-up period of 3.71 ± 2.49 years. Cox proportional hazard analysis indicated that the SHO risk increased by 3.58 (95% confidence interval [CI]: 1.859-6.754; P < .001) in patients with schizophrenia and viral hepatitis. Moreover, patients with schizophrenia having HCV had a higher SHO risk than those without viral hepatitis (hazard ratio: 5.07, 95% CI: 1.612-15.956; P < .0001). Patients having both schizophrenia and viral hepatitis, especially HCV, had a higher risk of SHOs.

Universal blood-borne virus screening in patients with severe mental illness managed in an outpatient clozapine clinic: uptake and prevalence

OBJECTIVE

Patients with a severe mental illness have higher rates of infection with blood-borne viruses (BBVs) but are less likely to access testing and treatment. Enhanced testing of this population is therefore warranted.

METHODS

In this single centre, prospective study, we sought to offer testing for BBVs to all patients who attended an appointment in the clozapine clinic (CC) over a six-month period. Those who consented were tested for HIV antigen/antibody, hepatitis C virus (HCV) antibody and hepatitis B virus surface antigen (HBsAg).

RESULTS

During the study period, 192 patients attended an appointment, of which 164 were offered testing. Of those, 134 (81.7%) accepted and 30 declined. Among patients who agreed to be tested, results were returned for 96 (71.6%). There were no positive results for HBsAg or HIV. Seven patients (7.2%) were positive for HCV antibody. Of those, three were newly identified exposures of which two were found to be chronically infected and were referred for treatment.

CONCLUSION

A routine offer of BBV testing for people with severe mental illness in the outpatient setting is feasible and may detect treatable infections.

Paliperidone is associated with reduced risk of severe hepatic outcome in patients with schizophrenia and viral hepatitis: A nationwide population-based cohort study

OBJECTIVE

Paliperidone, a second-generation antipsychotic, has been found to have minimal hepatotoxicity in patients with schizophrenia. However, long-term hepatic outcome in patients with schizophrenia and viral hepatitis remains unclear.

METHODS

Data obtained from the Taiwan National Health Insurance Research Database was used to enroll newly diagnosed schizophrenic patients between January 2007 and December 2013. Patients with schizophrenia and viral hepatitis who were receiving paliperidone were allocated to the paliperidone group while those who were not receiving paliperidone were allocated to the control group. Using a 1:2 ratio, we matched the age, sex, and index year to select the control participants. Patients with severe hepatic outcomes (SHOs) before enrollment were excluded. The two groups were studied until December 31, 2013. The primary endpoint was the occurrence of SHOs including liver failure, liver decompensation, liver transplantation, or liver cancer.

RESULTS

We identified 134 patients with schizophrenia and viral hepatitis who received paliperidone and 268 matched patients who did not receive paliperidone. Of the 402 patients, 22 (5.47%) developed SHOs during a mean follow-up period of 3.57 ± 1.62 years, including 2 (1.49%) from the paliperidone cohort and 20 (7.46%) from the control group. Furthermore, the Cox multivariate proportional hazards analysis revealed that the risk decreased with paliperidone use (adjusted hazard ratio [HR]: 0.155, 95% confidence interval [CI]: 0.032-0.737, p = 0.019) after adjusted for confounding factors.

CONCLUSION

Paliperidone treatment was associated with a reduced risk of SHOs in patients with schizophrenia and viral hepatitis.

Rates of hepatitis B and C in patients with schizophrenia: A meta-analysis

OBJECTIVE

Schizophrenia is associated with increased infectious disease comorbidity and mortality. Individuals with schizophrenia have increased risk of infectious hepatitis, potentially due to substance use comorbidity, sexual behaviors, and immunologic factors. We performed a systematic review and meta-analysis of the association between schizophrenia and hepatitis B and C.

METHOD

We searched major electronic databases from inception until January 2019 for prevalence and case-control studies of infectious hepatitis in patients with schizophrenia. Random effects meta-analyses calculating odds ratios (ORs) and 95% confidence intervals (CIs) for case-controls studies, prevalence and 95% CIs, and meta-regression analyses were performed.

RESULTS

Twenty-one studies met the inclusion criteria. In case-control studies, there was an over 3-fold increased odds of hepatitis C in patients with schizophrenia (OR = 3.29, 95% CI 1.50-7.23, p = 0.003), and a prevalence of 6% (ES = 0.06, 95% CI 0.04-0.08). In case-control studies, there was an over 2-fold increased odds of hepatitis B in patients with schizophrenia (OR = 2.36, 95% CI 1.61-3.47, p < 0.001) and a prevalence of 7% (ES = 0.07, 95% CI 0.03-0.11).

CONCLUSION

We found an approximately 3-fold increased odds of hepatitis B and C in patients with schizophrenia. This association may be due to an increased prevalence of environmental risk factors, increased susceptibility to infections, or both. Findings suggest that screening for infectious hepatitis may be germane to the clinical care of patients with schizophrenia and relevant risk factors.

Hepatitis C Treatment: Clinical Issues for Psychiatrists in the Post-Interferon Era

BACKGROUND

Hepatitis C virus (HCV) is a widespread and costly cause of morbidity and mortality globally and in the United States. The treatment of HCV has been revolutionized with the recent development of direct-acting antiviral medications. These new treatments are substantially better tolerated and more efficacious than previously used interferon-based therapies. Despite these innovations, sustained virologic response has remained low, hovering at approximately 9% of all infected persons. The reasons for this failure include lack of screening, low rates of linkage to care, cost of direct-acting antivirals, and barriers in access to care for patients. Psychiatrists work with patients at a disproportionately high risk for HCV infection yet many do not currently assume an active role in the HCV epidemic.

OBJECTIVE

The purpose of this clinical review is to familiarize psychiatrists with currently available hepatitis C treatments and discuss the remaining treatment challenges, including the high cost of treatment.

METHODS

The authors used information from the Centers for Disease Control and Food and Drug Administration on the most current estimates of HCV epidemiology, risk factors, and approved interferon-free treatments. PUBMED was searched for examples of HCV treatment in community psychiatry settings.

CONCLUSIONS

The mental health community is well-positioned to take on a more active role in HCV treatment and engage patients׳ trust in the treatment process. However, many barriers still exist. We encourage psychiatrists to assume a collaborative role in caring for psychiatric patients infected with HCV.

Prevalence of HIV, hepatitis B, and hepatitis C in people with severe mental illness: a systematic review and meta-analysis

BACKGROUND

Although people with serious mental illnesses have a high risk of contracting blood-borne viral infections, sexual health has largely been neglected by researchers and policy makers involved in mental health. Failure to address this shortcoming could increase morbidity and mortality as a result of undetected and untreated infection. We did a systematic review and meta-analysis to estimate the prevalence of blood-borne viral infection in people with serious mental illness.

METHOD

We searched the Cochrane Library, Medline, Embase, PsycInfo, CINAHL, and DARE for studies of the prevalence of HIV, hepatitis B virus, and hepatitis C virus in people with serious mental illness, published between Jan 1, 1980, and Jan 1, 2015. We group prevalence data by region and by virus and estimated pooled prevalence. We did a sensitivity analysis of the effect of study quality on prevalence.

FINDINGS

After removal of duplicates, we found 373 abstracts, 91 of which met our eligibility criteria. The prevalences of blood-borne viral infections in people with serious mental illness were higher than in the general population in places with low prevalence of blood-borne viruses, such as the USA and Europe, and on par with the general population in regions with high prevalence of blood-borne viruses (Africa for HIV and southeast Asia for hepatitis B virus and hepatitis C virus). Pooled prevalence of HIV in people with serious mental illness in the USA was 6·0% (95% CI 4·3-8·3). Sensitivity analysis showed that quality scores did not significantly affect prevalence.

INTERPRETATION

People with serious mental illness are at risk of blood-borne viral infections. However, because of methodological limitations of the studies the prevalence might be overestimated. Serious mental illness is unlikely to be a sole risk factor and risk of blood-borne viral infection is probably multifactorial and associated with low socioeconomic status, drug and alcohol misuse, ethnic origin, and sex. Health providers should routinely discuss sexual health and risks for blood-borne viruses (including risks related to drug misuse) with people who have serious mental illness, as well as offering testing and treatment for those at risk.

The efficacy and safety of treating hepatitis C in patients with a diagnosis of schizophrenia

Treating chronic hepatitis C with pegylated interferon alpha may induce or exacerbate psychiatric illness including depression, mania and aggressive behaviour. There is limited data regarding treatment in the context of chronic schizophrenia. We sought to establish the safety and efficacy of treating patients with schizophrenia. Patient and treatment data, prospectively collected on the Scottish hepatitis C database, were analysed according to the presence or absence of a diagnosis of schizophrenia. Time from referral to treatment, and the proportion of patients commencing treatment in each group, was calculated. Outcomes including sustained viral response rates, reasons for treatment termination and adverse events were compared. Of 5497 patients, 64 (1.2%) had a diagnosis of schizophrenia. Patients with schizophrenia (PWS) were as likely to receive treatment as those without [28/61(46%) vs 1639/4415 (37%) P = 0.19]. Sustained viral response (SVR) rates were higher in PWS [21/25 (84%) vs 788/1453 (54%) P < 0.01]. SVR rates by genotype were similar [4/8 (50%) vs 239/684 (35%) Genotype 1 (P = 0.56), 17/17 (100%) vs 599/742 (81%) non-Genotype 1 (P = 0.09)]. Adverse events leading to cessation of treatment were comparable [2/25(8%) vs 189/1453 (13%) P: 0.66]. Patients with schizophrenia are good candidates for hepatitis C treatment, with equivalent SVR and treatment discontinuation rates to patients without schizophrenia.

Outcomes of hepatitis C screening programs targeted at risk groups hidden in the general population: a systematic review

BACKGROUND

Effective screening programs are urgently needed to provide undiagnosed hepatitis C virus (HCV)-infected individuals with therapy. This systematic review of characteristics and outcomes of screening programs for HCV focuses on strategies to identify HCV risk groups hidden in the general population.

METHODS

We conducted a comprehensive search of MEDLINE and EMBASE databases for articles published between 1991-2010, including studies that screened the general population using either a newly developed (nonintegrated) screening program or one integrated in existing health care facilities. Look-back studies, prevalence studies, and programs targeting high-risk groups in care (e.g., current drug users) were excluded.

RESULTS

After reviewing 7052 studies, we identified 67 screening programs: 24 nonintegrated; 41 programs integrated in a variety of health care facilities (e.g., general practitioner); and 2 programs with both integrated and nonintegrated strategies. Together, these programs identified approximately 25,700 HCV-infected individuals. In general, higher HCV prevalence was found in programs in countries with intermediate to high HCV prevalence, in psychiatric clinics, and in programs that used a prescreening selection based on HCV risk factors. Only 6 programs used a comparison group for evaluation purposes, and 1 program used theory about effective promotion for screening. Comparison of the programs and their effectiveness was hampered by lack of reported data on program characteristics, clinical follow-up, and type of diagnostic test.

CONCLUSIONS

A prescreening selection based on risk factors can increase the efficiency of screening in low-prevalence populations, and we need programs with comparison groups to evaluate effectiveness. Also, program characteristics such as type of diagnostic test, screening uptake, and clinical outcomes should be reported systematically.

Hepatotoxicity induced by clozapine: a case report and review of literature

Clozapine is an effective antipsychotic drug but is associated with serious side effects. Most treatment guidelines give no clear recommendations on regular monitoring of liver function tests, even though up to 60% of patients experience elevations in hepatic transaminases, with 15% to 30% experiencing an elevation two to three times greater than normal. Though elevations in liver function tests are often transient and asymptomatic, there are many reported cases of clozapine-induced hepatotoxicity, with damage to the liver, involvement of multiple organs, and even fulminant liver failure arising with moderate clozapine doses. This case report describes a Chinese woman who developed hepatotoxicity on a low dose of clozapine, and reviews the relevant literature.

Psychiatric treatment considerations with direct acting antivirals in hepatitis C

Background

Despite recent advances in hepatitis C (HCV) treatment, specifically the addition of direct acting antivirals (DAAs), pegylated interferon-alpha remains the backbone of HCV therapy. Therefore, the impact of DAAs on the management of co-morbid psychiatric illness and neuropsychiatric sequalae remains an ongoing concern during HCV therapy. This paper provides a review of the neuropsychiatric adverse effects of DAAs and drug-drug interactions (DDIs) between DAAs and psychiatric medications.

Methods

We conducted a Pubmed search using relevant search terms and hand searched reference lists of related review articles. In addition, we searched abstracts for major hepatology conferences and contacted respective pharmaceutical companies for additional studies.

Results

Limited data is available on the neuropsychiatric adverse effects of DAAs; however, data from major clinical trials suggest that DAAs have minimal neuropsychiatric risk. DAAs can potentially interact with a variety of psychotropic agents via cytochrome P450 and p-glycoprotein interactions. Triazolam, oral midazolam, St. John’s Wort, carbamazepine and pimozide, are contraindicated with DAAs. DDIs between DAAs and antidepressants, anxiolytics, hypnotics, mood stabilizers, antipsychotics and treatments for opioid dependence are summarized.

Conclusions

Although DAAs do not add significant neuropsychiatric risk, the potential for DDIs is high. Consideration of DDIs is paramount to improving medication adherence and mitigating adverse effects during HCV therapy.

Provision of preventive services for cancer and infectious diseases among individuals with serious mental illness

Individuals living with serious mental illness (SMI) have increased mortality chiefly because of a higher prevalence of chronic disorders, including some cancers and infectious diseases. Although increased prevalence of these disorders may be attributable to lifestyle and risk behaviors, there is evidence that they may not be appropriately addressed by health professionals. We conducted a review of the literature describing preventive services for cancer and infectious diseases provided to individuals with SMI. Most studies demonstrated a 20%-30% reduced likelihood of breast, cervical, and colorectal cancer screening, or immunizations for influenza and pneumonia, in patients with SMI compared with those without SMI. This is most common in those with the most severe forms of SMI. HIV and hepatitis were more commonly screened for in people with SMI than the general population, likely because of the increased risk for these disorders within this group, but there were still substantial proportions of individuals with SMI who had never received a screening, or had not received a recent screening, for these disorders. The mental health nursing profession has an opportunity to address the disparity in care for cancer and infectious diseases, as well as other physical disorders, experienced by mental health consumers. With systemic support and ongoing education, mental health nurses may be capable of conducting or recommending screening for disorders and providing lifestyle advice. These practices may help to reduce the increased prevalence of chronic disease in SMI populations.

Determining rates of hepatitis C in a clozapine treated cohort

OBJECTIVE

To determine the prevalence rates of hepatitis C in patients with schizophrenia and schizoaffective disorder being treated with clozapine.

METHODS

Clozapine-treated outpatients and inpatients were recruited from the Centre for Addiction and Mental Health Schizophrenia Program in Toronto, Canada. All subjects had liver function tests, and positive HCV status was defined as a positive qualitative HCV RNA assay. Subjects completed a self-report questionnaire assessing HCV risk factors, past history of liver disease, previous diagnosis of human immunodeficiency virus (HIV), past hepatitis B virus (HBV) infection and current alcohol use.

RESULTS

110 subjects participated in the study and the HCV prevalence rate (antibody and viremia-positive) was 2.7%, compared to a 0.8% prevalence rate in Canada. All study subjects had established housing, none reported a history of HIV, and only one patient had a history of HBV infection. A total of 9% drank two or more drinks on a typical day drinking and 7% endorsed having six or more drinks on one occasion at least monthly. Two of 3HCV-viremia positive subjects had HCV risk factors, specifically intravenous drug use and intranasal cocaine use. There was no difference between HCV infected and HCV negative subjects on liver function tests.

CONCLUSIONS

Our study demonstrates elevated rates of HCV in clozapine-treated patients compared to the general population in Canada and are congruent with reports from United States centres. Our study highlights the importance of homelessness and patterns of high-risk behaviour when interpreting HCV prevalence rates in this sub-population of patients and should be explored in future studies.

[Management of patients with hepatitis C by French psychologists and psychiatrists: a practical investigation]

INTRODUCTION

A first part of this survey showed that up to 19% of patients with hepatitis C virus did not receive optimal treatment because of a psychiatric problem (psychiatric disorders or addictive behaviours) and that less than 50% of the managing clinicians worked with a psychiatrist or a psychologist in these cases. The aim of the second part of the survey was to describe the current practices provided by the psychiatrists and the psychologists to HCV infected patients as well as the knowledge and expectations of professionals in this area.

PATIENTS AND METHODS

Forty-seven psychiatrists and 43 psychologists who were or were not working with French reference poles for hepatitis C virus responded to a questionnaire of their practices.

RESULTS

Analysis of the 90 questionnaires showed that psychiatric and/or psychological care was not systematic. Psychiatrists and psychologists should be given more information and specific training about this topic.

CONCLUSION

Psychiatric and psychological care of chronic hepatitis C virus infected patients should be improved. French reference poles should also become "references" for psychiatric care.

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.

HIV, syphilis, and hepatitis B and C prevalence among patients with mental illness: a review of the literature

A limited number of studies worldwide have investigated the prevalence of HIV, syphilis, and hepatitis B and C infection among psychiatric patients. However, prevalence of these infections in the population with chronic mental illness has not been clearly established. Most of the published papers are from developed countries and have derived from relatively small and non-representative samples. We performed a systematic review of the published literature to identify studies on these infectious diseases within psychiatric populations in Brazil and other developing countries. Overall, prevalence rates varied from 0% to 29% for HIV; 1.6% to 66% for HBV; 0.4% to 38% for HCV; and 1.1% to 7.6% for syphilis. Several risk factors were identified and discussed, although sampling limitations restrict the generalization of study findings. This review highlights the lack of information on the prevalence of sexually transmitted diseases and their associated factors among persons with chronic mental illness and identifies gaps in the knowledge base in both developing and developed countries.
