Who sleeps well in Canada? The social determinants of sleep health among middle-aged and older adults in the Canadian Longitudinal Study on Aging

OBJECTIVES

Sleep health inequities likely contribute to disparities in health outcomes. Our objective was to identify social determinants of sleep health among middle-aged/older adults in Canada, where prior evidence is limited.

METHODS

We analyzed cross-sectional data from the Canadian Longitudinal Study on Aging, a survey of over 30,000 community-dwelling adults aged 45-85years. Self-reported measures included sleep duration, sleep satisfaction, and sleep efficiency. We explored associations between sleep measures and social determinants of health. We used modified Poisson regression to estimate prevalence ratios for sleep satisfaction and sleep efficiency, and linear regression for sleep duration. Estimates were adjusted for all social, lifestyle, and clinical covariates. We explored effect modification by sex.

RESULTS

Of the 11 social determinants explored, all were significantly associated with at least one domain of sleep health. These associations were reduced to 9 variables with adjustment for all social variables, and 7 with further adjustment for lifestyle and clinical covariates, including differences by sex, age, education, marital status, employment, race/ethnicity, and sexual orientation. Better sleep health in >1 domain was observed among males, older age groups (65 and older), higher income groups, the retired group, and homeowners with adjustment for social variables, and only in males and older age groups with additional adjustment for lifestyle and clinical variables. Only sleep duration associations were modified by sex.

CONCLUSIONS

Sleep health disparities among Canadian adults exist across socioeconomic gradients and racial/ethnic minority groups. Poor sleep health among disadvantaged groups warrants increased attention as a public health problem in Canada.

Pharmacological treatments in panic disorder in adults: a network meta-analysis

BACKGROUND

A panic attack is a discrete period of fear or anxiety that has a rapid onset and reaches a peak within 10 minutes. The main symptoms involve bodily systems, such as racing heart, chest pain, sweating, shaking, dizziness, flushing, churning stomach, faintness and breathlessness. Other recognised panic attack symptoms involve fearful cognitions, such as the fear of collapse, going mad or dying, and derealisation (the sensation that the world is unreal). Panic disorder is common in the general population with a prevalence of 1% to 4%. The treatment of panic disorder includes psychological and pharmacological interventions, including antidepressants and benzodiazepines.

OBJECTIVES

To compare, via network meta-analysis, individual drugs (antidepressants and benzodiazepines) or placebo in terms of efficacy and acceptability in the acute treatment of panic disorder, with or without agoraphobia. To rank individual active drugs for panic disorder (antidepressants, benzodiazepines and placebo) according to their effectiveness and acceptability. To rank drug classes for panic disorder (selective serotonin reuptake inhibitors (SSRIs), serotonin-norepinephrine reuptake inhibitors (SNRIs), tricyclic antidepressants (TCAs), mono-amine oxidase inhibitors (MAOIs) and benzodiazepines (BDZs) and placebo) according to their effectiveness and acceptability. To explore heterogeneity and inconsistency between direct and indirect evidence in a network meta-analysis.

SEARCH METHODS

We searched the Cochrane Common Mental Disorders Specialised Register, CENTRAL, CDSR, MEDLINE, Ovid Embase and PsycINFO to 26 May 2022.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) of people aged 18 years or older of either sex and any ethnicity with clinically diagnosed panic disorder, with or without agoraphobia. We included trials that compared the effectiveness of antidepressants and benzodiazepines with each other or with a placebo.

DATA COLLECTION AND ANALYSIS

Two authors independently screened titles/abstracts and full texts, extracted data and assessed risk of bias. We analysed dichotomous data and continuous data as risk ratios (RRs), mean differences (MD) or standardised mean differences (SMD): response to treatment (i.e. substantial improvement from baseline as defined by the original investigators: dichotomous outcome), total number of dropouts due to any reason (as a proxy measure of treatment acceptability: dichotomous outcome), remission (i.e. satisfactory end state as defined by global judgement of the original investigators: dichotomous outcome), panic symptom scales and global judgement (continuous outcome), frequency of panic attacks (as recorded, for example, by a panic diary; continuous outcome), agoraphobia (dichotomous outcome). We assessed the certainty of evidence using threshold analyses.

MAIN RESULTS

Overall, we included 70 trials in this review. Sample sizes ranged between 5 and 445 participants in each arm, and the total sample size per study ranged from 10 to 1168. Thirty-five studies included sample sizes of over 100 participants. There is evidence from 48 RCTs (N = 10,118) that most medications are more effective in the response outcome than placebo. In particular, diazepam, alprazolam, clonazepam, paroxetine, venlafaxine, clomipramine, fluoxetine and adinazolam showed the strongest effect, with diazepam, alprazolam and clonazepam ranking as the most effective. We found heterogeneity in most of the comparisons, but our threshold analyses suggest that this is unlikely to impact the findings of the network meta-analysis. Results from 64 RCTs (N = 12,310) suggest that most medications are associated with either a reduced or similar risk of dropouts to placebo. Alprazolam and diazepam were associated with a lower dropout rate compared to placebo and were ranked as the most tolerated of all the medications examined. Thirty-two RCTs (N = 8569) were included in the remission outcome. Most medications were more effective than placebo, namely desipramine, fluoxetine, clonazepam, diazepam, fluvoxamine, imipramine, venlafaxine and paroxetine, and their effects were clinically meaningful. Amongst these medications, desipramine and alprazolam were ranked highest. Thirty-five RCTs (N = 8826) are included in the continuous outcome reduction in panic scale scores. Brofaromine, clonazepam and reboxetine had the strongest reductions in panic symptoms compared to placebo, but results were based on either one trial or very small trials. Forty-one RCTs (N = 7853) are included in the frequency of panic attack outcome. Only clonazepam and alprazolam showed a strong reduction in the frequency of panic attacks compared to placebo, and were ranked highest. Twenty-six RCTs (N = 7044) provided data for agoraphobia. The strongest reductions in agoraphobia symptoms were found for citalopram, reboxetine, escitalopram, clomipramine and diazepam, compared to placebo. For the pooled intervention classes, we examined the two primary outcomes (response and dropout). The classes of medication were: SSRIs, SNRIs, TCAs, MAOIs and BDZs. For the response outcome, all classes of medications examined were more effective than placebo. TCAs as a class ranked as the most effective, followed by BDZs and MAOIs. SSRIs as a class ranked fifth on average, while SNRIs were ranked lowest. When we compared classes of medication with each other for the response outcome, we found no difference between classes. Comparisons between MAOIs and TCAs and between BDZs and TCAs also suggested no differences between these medications, but the results were imprecise. For the dropout outcome, BDZs were the only class associated with a lower dropout compared to placebo and were ranked first in terms of tolerability. The other classes did not show any difference in dropouts compared to placebo. In terms of ranking, TCAs are on average second to BDZs, followed by SNRIs, then by SSRIs and lastly by MAOIs. BDZs were associated with lower dropout rates compared to SSRIs, SNRIs and TCAs. The quality of the studies comparing antidepressants with placebo was moderate, while the quality of the studies comparing BDZs with placebo and antidepressants was low.

AUTHORS' CONCLUSIONS

In terms of efficacy, SSRIs, SNRIs (venlafaxine), TCAs, MAOIs and BDZs may be effective, with little difference between classes. However, it is important to note that the reliability of these findings may be limited due to the overall low quality of the studies, with all having unclear or high risk of bias across multiple domains. Within classes, some differences emerged. For example, amongst the SSRIs paroxetine and fluoxetine seem to have stronger evidence of efficacy than sertraline. Benzodiazepines appear to have a small but significant advantage in terms of tolerability (incidence of dropouts) over other classes.

A Systematic Review of the Effect of Short Term Transcranial Direct Current Stimulation Therapy in Methamphetamine Use Disorder

Background: Methamphetamine use disorder (MUD) has become more and more common. Some studies have shown that Transcranial Direct Current stimulation (tDCS) may reduce craving when stimulating the dorsal lateral prefrontal cortex. Objectives: The aim of this systematic review was to evaluate the effect of transcranial direct current stimulation (tDCS) on MUD. Databases were searched through May 2022. Randomized Controlled Trials (RCT) and pre-post studies investigating the efficacy of tDCS in MUD were included. The Cochrane Manual of Systematic Evaluation 6.3 bias risk assessment tool was used to assess the risk of bias. For each article, where possible, we extracted the population(s), standardized mean differences (SMD), standard deviations, and other study metrics (design, year, randomization, and details) on efficacy and tolerability outcomes. We assessed each article's quality via the GRADE assessment protocol. Results: Six studies involving 220 patients were included. All six studies included reported continuous data on craving. Results from craving favored active tDCS over sham tDCS at the end of treatment (SMD -0.58, 95% CI -0.85 to -0.30; studies = 6, participants = 220; I2 = 60%). Tolerability data showed that tDCS does not cause more tingling or itching sensation compared to sham tDCS. Conclusions: Further trials with larger sample sizes and longer durations are needed to determine whether tDCS is a valuable tool in treating MUD.

Cognitive behavioural therapy (group) for schizophrenia

BACKGROUND

Schizophrenia is a disabling psychotic disorder characterised by positive symptoms of delusions, hallucinations, disorganised speech and behaviour; and negative symptoms such as affective flattening and lack of motivation. Cognitive behavioural therapy (CBT) is a psychological intervention that aims to change the way in which a person interprets and evaluates their experiences, helping them to identify and link feelings and patterns of thinking that underpin distress. CBT models targeting symptoms of psychosis (CBTp) have been developed for many mental health conditions including schizophrenia. CBTp has been suggested as a useful add-on therapy to medication for people with schizophrenia. While CBT for people with schizophrenia was mainly developed as an individual treatment, it is expensive and a group approach may be more cost-effective. Group CBTp can be defined as a group intervention targeting psychotic symptoms, based on the cognitive behavioural model. In group CBTp, people work collaboratively on coping with distressing hallucinations, analysing evidence for their delusions, and developing problem-solving and social skills. However, the evidence for effectiveness is far from conclusive.

OBJECTIVES

To investigate efficacy and acceptability of group CBT applied to psychosis compared with standard care or other psychosocial interventions, for people with schizophrenia or schizoaffective disorder.

SEARCH METHODS

On 10 February 2021, we searched the Cochrane Schizophrenia Group's Study-Based Register of Trials, which is based on CENTRAL, MEDLINE, Embase, four other databases and two trials registries. We handsearched the reference lists of relevant papers and previous systematic reviews and contacted experts in the field for supplemental data.

SELECTION CRITERIA

We selected randomised controlled trials allocating adults with schizophrenia to receive either group CBT for schizophrenia, compared with standard care, or any other psychosocial intervention (group or individual).

DATA COLLECTION AND ANALYSIS

We complied with Cochrane recommended standard of conduct for data screening and collection. Where possible, we calculated risk ratio (RR) and 95% confidence interval (CI) for binary data and mean difference (MD) and 95% CI for continuous data. We used a random-effects model for analyses. We assessed risk of bias for included studies and created a summary of findings table using GRADE.

MAIN RESULTS

The review includes 24 studies (1900 participants). All studies compared group CBTp with treatments that a person with schizophrenia would normally receive in a standard mental health service (standard care) or any other psychosocial intervention (group or individual). None of the studies compared group CBTp with individual CBTp. Overall risk of bias within the trials was moderate to low. We found no studies reporting data for our primary outcome of clinically important change. With regard to numbers of participants leaving the study early, group CBTp has little or no effect compared to standard care or other psychosocial interventions (RR 1.22, 95% CI 0.94 to 1.59; studies = 13, participants = 1267; I2 = 9%; low-certainty evidence). Group CBTp may have some advantage over standard care or other psychosocial interventions for overall mental state at the end of treatment for endpoint scores on the Positive and Negative Syndrome Scale (PANSS) total (MD -3.73, 95% CI -4.63 to -2.83; studies = 12, participants = 1036; I2 = 5%; low-certainty evidence). Group CBTp seems to have little or no effect on PANSS positive symptoms (MD -0.45, 95% CI -1.30 to 0.40; studies =8, participants = 539; I2 = 0%) and on PANSS negative symptoms scores at the end of treatment (MD -0.73, 95% CI -1.68 to 0.21; studies = 9, participants = 768; I2 = 65%). Group CBTp seems to have an advantage over standard care or other psychosocial interventions on global functioning measured by Global Assessment of Functioning (GAF; MD -3.61, 95% CI -6.37 to -0.84; studies = 5, participants = 254; I2 = 0%; moderate-certainty evidence), Personal and Social Performance Scale (PSP; MD 3.30, 95% CI 2.00 to 4.60; studies = 1, participants = 100), and Social Disability Screening Schedule (SDSS; MD -1.27, 95% CI -2.46 to -0.08; studies = 1, participants = 116). Service use data were equivocal with no real differences between treatment groups for number of participants hospitalised (RR 0.78, 95% CI 0.38 to 1.60; studies = 3, participants = 235; I2 = 34%). There was no clear difference between group CBTp and standard care or other psychosocial interventions endpoint scores on depression and quality of life outcomes, except for quality of life measured by World Health Organization Quality of Life Assessment Instrument (WHOQOL-BREF) Psychological domain subscale (MD -4.64, 95% CI -9.04 to -0.24; studies = 2, participants = 132; I2 = 77%). The studies did not report relapse or adverse effects.

AUTHORS' CONCLUSIONS

Group CBTp appears to be no better or worse than standard care or other psychosocial interventions for people with schizophrenia in terms of leaving the study early, service use and general quality of life. Group CBTp seems to be more effective than standard care or other psychosocial interventions on overall mental state and global functioning scores. These results may not be widely applicable as each study had a low sample size. Therefore, no firm conclusions concerning the efficacy of group CBTp for people with schizophrenia can currently be made. More high-quality research, reporting useable and relevant data is needed.

A Systematic Review of the Use of Telepsychiatry in Depression

Telepsychiatry, the use of televideo in psychiatric assessment and treatment, is utilized throughout Canada. Major depressive disorder (MDD) is common, with significant burdens of suffering and cost. This systematic review explores the literature on the use of televideo to diagnose and treat MDD, particularly acceptability and patient satisfaction, efficacy, and cost-effectiveness. A literature search was conducted for years 1946 to 2019. Study eligibility criteria included: MDD as the condition of interest, use of televideo technology, randomized controlled trials (RCTs), Adult (18 years or older) population, any clinical setting, and any healthcare professional providing care. The study must have included at least one of the following measures, satisfaction, efficacy, and cost-effectiveness. Fourteen studies were included. Satisfaction is equivalent to or significantly higher than face-to-face intervention. Both televideo and control groups found relief from depressive symptoms, with differences either statistically insignificant or in favour of televideo. Despite increased cost upfront for televideo due to the technology required, televideo would eventually be more cost-effective due to reducing travel expenses. Limitations include that there is little RCT data, and what exists often uses a collaborative treatment model. Many studies consisted solely of U.S. Veterans, and have limited generalizability. Further research needed to directly compare psychiatrist assessment over televideo versus in-person, and determine if particular patient subgroups benefit more from televideo or in-person intervention.Systematic review registration number: CRD42016048224.

The Impact of Infectious Disease-Related Public Health Emergencies on Suicide, Suicidal Behavior, and Suicidal Thoughts

Abstract. Background: Infectious disease-related public health emergencies (epidemics) may increase suicide risk, and high-quality evidence is needed to guide an international response. Aims: We investigated the potential impacts of epidemics on suicide-related outcomes. Method: We searched MEDLINE, EMBASE, PsycInfo, CINAHL, Scopus, Web of Science, PsyArXiv, medRxiv, and bioRxiv from inception to May 13–16, 2020. Inclusion criteria: primary studies, reviews, and meta-analyses; reporting the impact of epidemics; with a primary outcome of suicide, suicidal behavior, suicidal ideation, and/or self-harm. Exclusion criteria: not concerned with suicide-related outcomes; not suitable for data extraction. PROSPERO registration: #CRD42020187013. Results: Eight primary papers were included, examining the effects of five epidemics on suicide-related outcomes. There was evidence of increased suicide rates among older adults during SARS and in the year following the epidemic (possibly motivated by social disconnectedness, fears of virus infection, and concern about burdening others) and associations between SARS/Ebola exposure and increased suicide attempts. A preprint study reported associations between COVID-19 distress and past-month suicidal ideation. Limitations: Few studies have investigated the topic; these are of relatively low methodological quality. Conclusion: Findings support an association between previous epidemics and increased risk of suicide-related outcomes. Research is needed to investigate the impact of COVID-19 on suicide outcomes.

Sleep behaviours and multimorbidity occurrence in middle-aged and older adults: findings from the Canadian Longitudinal Study on Aging (CLSA)

OBJECTIVE

Poor sleep quality and reduced sleep duration impact over half of older adults and are associated with adverse health outcomes, such as multiple chronic conditions (multimorbidity) and reduced longevity. Our objective was to examine the relationship between sleep behaviours and multimorbidity in Canada.

METHODS

We analysed data from the Canadian Longitudinal Study on Aging (CLSA), a cross-sectional national health survey of community-dwelling adults over the age of 45 years. A total of 30,011 participants had physiological and psychosocial data collected at baseline. Sleep measures included self-reported sleep duration (short: <6 h; normal: 6-8 h; long: >8 h) and sleep quality (dissatisfied/very dissatisfied; neutral; satisfied/very satisfied). Multimorbidity was defined using two definitions (public health and primary care) and two cut-points (2 or more and 3 or more chronic conditions).

RESULTS

Approximately 70% were living with multimorbidity using the primary care definition (females: 67.9%; males 57.9%), whereas approximately 30% were living with multimorbidity using the public health definition (females: 30.9%; males: 24.0%). Adjusted analyses indicated that the odds of multimorbidity were higher for participants who selfreported either short or long sleep duration, as well as dissatisfaction with sleep quality. Associations were stronger among younger age groups (45-54 years and 55-64 years).

CONCLUSIONS

Disrupted sleep may be a risk factor for multimorbidity across sexes and age groups. It is necessary to understand the potential impact of sleep on the risk of multimorbidity to inform both clinical and public health guidelines for the prevention and management of this major health issue.

Trends in the use of the Italian Mental Health Act, 1979–1997

Italian statistics on psychiatric bed availability, voluntary and compulsory admissions were examined from 1979 to 1997. Although the number of psychiatric beds dropped by 62.5%, the absolute number of compulsory admissions has remained substantially stable. The proportion of all admissions that were compulsory decreased from 17.1% to 11%. This study shows that a shift to community care was not associated with an increase in compulsory admissions in Italy.

Relationship between sleep patterns and multimorbidity in the Canadian Longitudinal Study on Aging

Background

Sleep difficulties are an unmet public health problem, affecting large segments of the population around the world. Poor sleep quality and reduced sleep duration impact over half of older adults and are associated with adverse health outcomes like multiple chronic diseases (multimorbidity) and reduced longevity.

Methods

A cross-sectional analysis of the Canadian Longitudinal Study on Aging (CLSA), a national health survey of community-dwelling adults and older adults. A total of 30,011 participants had physiological and psychosocial data collected at baseline. Sleep measures included self-reported sleep duration (short: &lt;6 hours, normal: 6-8 hours, long: &gt;8 hours) and sleep quality (dissatisfied/very dissatisfied, neutral, satisfied/very satisfied). To capture multimorbidity, a primary definition was operationalized with 17 chronic conditions, whereas a secondary definition was operationalized with 9 chronic conditions to capture both the primary care and public health perspective.

Results

In our sample, 50.9% were female (average age: 62.7 years) and 49.1% were male (average age: 63.2 years). The majority reported a normal sleep duration and approximately half reported being either satisfied or very satisfied with sleep quality. About 70% were living with multimorbidity using the primary care definition (females: 71.7%; males 64.3%), while about 30% were living with multimorbidity using the public health definition (females: 34.8%; males: 28.9%). The adjusted analyses indicated the odds of multimorbidity increased for those who reported short or long sleep duration, as well as dissatisfaction with sleep quality, across age groups and both females and males.

Conclusions

Disrupted sleep may be an additional behavioural risk factor for a number of chronic diseases, in the context of aging populations. It is necessary to understand the potential impact of sleep on the risk of multimorbidity, and this research will build knowledge in this important area.

Key messages

This research will utilize a national health survey to examine and report the characteristics of sleep quality and sleep duration among approximately 30,000 community-dwelling adults in Canada. This research will explore relationships between sleep duration, sleep quality and multimorbidity (controlling for confounding factors) among community-dwelling adults in Canada.

Sleep and Mental Health Among Older Adults in the Canadian Longitudinal Study on Aging

Background

Global studies have demonstrated consistent associations between sleep problems and mental health and well-being in older adults, however Canadian data are lacking. We investigated associations between sleep quantity and quality with both mental illness symptoms and well-being among older adults in Canada.

Methods

We used cross-sectional baseline data from the Canadian Longitudinal Study on Aging, a national survey of 30,097 community-dwelling adults aged 45 years and older. Self-reported sleep measures included average past-week sleep duration (short [&lt;6h], normal [6-8h], long [&gt;8h]), and sleep quality (satisfied or dissatisfied vs neutral). Mental illness outcomes included depressive symptoms and psychological distress. Mental well-being outcomes included self-rated mental health and satisfaction with life. We used modified Poisson regression models with adjustment for sociodemographic, behavioural, and clinical factors, and stratification by sex and age to explore effect modification.

Results

In the unadjusted analysis, short and long sleep duration and sleep dissatisfaction were associated with higher mental illness symptoms and lower well-being across all outcomes. Sleep satisfaction was associated with a lower likelihood of mental illness symptoms and better well-being. Short sleep duration was associated with the largest effects on mental health outcomes. Self-rated mental health and depressive symptoms had the largest associations with sleep measures. Effects were larger in males and the 45 to 54 year age group.

Conclusions

Preliminary evidence suggests sleep duration and quality are associated with symptoms of depression, psychological distress, and poor mental well-being among older adults. We are unable to determine whether sleep problems are a cause or consequence of poor mental health. Nonetheless, sleep may be an important target for public health initiatives to improve mental health and well-being among older adults.

Key messages

Our findings contribute further evidence that sleep difficulties are associated with adverse health outcomes including higher mental illness symptoms and lower well-being among older adults. Sleep disturbances are an unmet public health problem, and may be an important target for public health initiatives to improve mental health and well-being among older adults.

Influence of covariates on heterogeneity in Hamilton Anxiety Scale ratings in placebo-controlled trials of benzodiazepines in generalized anxiety disorder: Systematic review and meta-analysis

BACKGROUND

Generalized anxiety disorder is a common psychiatric condition that is associated with decreased quality of life and significant disability. Benzodiazepines are anti-anxiety drugs used widely in the treatment of generalized anxiety disorder. This study examines the influence of several variables on benzodiazepine efficacy in generalized anxiety disorder.

METHOD

We performed a systematic review of placebo-controlled randomized controlled trials with benzodiazepines in generalized anxiety disorder. Fifty-eight studies were deemed eligible to include in the meta-analysis. The studies dated from 1977 to 2013 and included over 5400 participants. From each paper, we extracted: benzodiazepine name and dose, dosing regimen, baseline Hamilton Anxiety Scale (HAM-A) score, change in HAM-A score at study endpoint, drop-out rate, year of study publication, diagnostic criteria used, study size, study duration, location, any conflicts of interest and side-effect profile. We then assessed the influence, direct and indirect, of individual variables on the primary outcome (mean difference at endpoint, HAM-A score).

RESULTS

Three factors were shown to be associated statistically with change in HAM-A; baseline HAM-A for benzodiazepine arm, baseline HAM-A for the placebo arm, and duration of the study. A higher baseline HAM-A in both arms was associated with a greater mean difference in HAM-A. A shorter study length was also associated with a greater mean difference.

DISCUSSION

The major factors determining benzodiazepine response was baseline anxiety level for the benzodiazepine arm and study duration. In any design of further meta-analyses and clinical trials for generalized anxiety disorder we suggest that these should be considered these as confounding factors.

Benzodiazepines versus placebo for panic disorder in adults

BACKGROUND

Panic disorder is characterised by recurrent unexpected panic attacks consisting of a wave of intense fear that reaches a peak within a few minutes. Panic disorder is a common disorder, with an estimated lifetime prevalence of 1% to 5% in the general population and a 7% to 10% prevalence in primary care settings. Its aetiology is not fully understood and is probably heterogeneous.Panic disorder is treated with psychological and pharmacological interventions, often used in combination. Although benzodiazepines are frequently used in the treatment of panic disorder, guidelines recommend antidepressants, mainly selective serotonin reuptake inhibitors (SSRIs), as first-line treatment for panic disorder, particularly due to their lower incidence of dependence and withdrawal reaction when compared to benzodiazepines. Despite these recommendations, benzodiazepines are widely used in the treatment of panic disorder, probably because of their rapid onset of action.

OBJECTIVES

To assess the efficacy and acceptability of benzodiazepines versus placebo in the treatment of panic disorder with or without agoraphobia in adults.

SEARCH METHODS

We searched the Cochrane Common Mental Disorders Controlled Trials Register (CCMDCTR Studies and References), the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (1950-), Embase (1974-), and PsycINFO (1967-) up to 29 May 2018. We handsearched reference lists of relevant papers and previous systematic reviews. We contacted experts in the field for supplemental data.

SELECTION CRITERIA

All double-blind (blinding of patients and personnel) controlled trials randomising adults with panic disorder with or without agoraphobia to benzodiazepine or placebo.

DATA COLLECTION AND ANALYSIS

Two review authors independently checked the eligibility of studies and extracted data using a standardised form. Data were then entered data into Review Manager 5 using a double-check procedure. Information extracted included study characteristics, participant characteristics, intervention details, settings, and outcome measures in terms of efficacy, acceptability, and tolerability.

MAIN RESULTS

We included 24 studies in the review with a total of 4233 participants, of which 2124 were randomised to benzodiazepines and 1475 to placebo. The remaining 634 participants were randomised to other active treatments in three-arm trials. We assessed the overall methodological quality of the included studies as poor. We rated all studies as at unclear risk of bias in at least three domains. In addition, we judged 20 of the 24 included studies as having a high risk of bias in at least one domain.Two primary outcomes of efficacy and acceptability showed a possible advantage of benzodiazepines over placebo. The estimated risk ratio (RR) for a response to treatment was 1.65 (95% confidence interval (CI) 1.39 to 1.96) in favour of benzodiazepines, which corresponds to an estimated number needed to treat for an additional beneficial outcome (NNTB) of 4 (95% CI 3 to 7). The dropout rate was lower among participants treated with benzodiazepines (RR 0.50, 95% CI 0.39 to 0.64); the estimated NNTB was 6 (95% CI 5 to 9). We rated the quality of the evidence as low for both primary outcomes. The possible advantage of benzodiazepine was also seen for remission (RR 1.61, 95% CI 1.38 to 1.88) and the endpoint data for social functioning (standardised mean difference (SMD) -0.53, 95% CI -0.65 to -0.42), both with low-quality evidence. We assessed the evidence for the other secondary outcomes as of very low quality. With the exception of the analyses of the change score data for depression (SMD -0.22, 95% CI -0.48 to 0.04) and social functioning (SMD -0.32, 95% CI -0.88 to 0.24), all secondary outcome analyses showed an effect in favour of benzodiazepines compared to placebo. However, the number of dropouts due to adverse effects was higher with benzodiazepines than with placebo (RR 1.58, 95% CI 1.16 to 2.15; low-quality evidence). Furthermore, our analyses of adverse events showed that a higher proportion of participants experienced at least one adverse effect when treated with benzodiazepines (RR 1.18, 95% CI 1.02 to 1.37; low-quality evidence).

AUTHORS' CONCLUSIONS

Low-quality evidence shows a possible superiority of benzodiazepine over placebo in the short-term treatment of panic disorders. The validity of the included studies is questionable due to possible unmasking of allocated treatments, high dropout rates, and probable publication bias. Moreover, the included studies were only short-term studies and did not examine the long-term efficacy nor the risks of dependency and withdrawal symptoms. Due to these limitations, our results regarding the efficacy of benzodiazepines versus placebo provide only limited guidance for clinical practice. Furthermore, the clinician's choice is not between benzodiazepines and placebo, but between benzodiazepines and other agents, notably SSRIs, both in terms of efficacy and adverse effects. The choice of treatment should therefore be guided by the patient's preference and should balance benefits and harms from treatment in a long-term perspective.

A Comparison of Inpatient Adult Psychiatric Services in Italy and Canada

We examine the possibility the Organisation for Economic Co-operation and Development (OECD) bed count for Italy may be an underestimation of the actual beds available. We compared bedded services for mental disorders in two regions in Italy and Canada respectively. We found out that if we consider acute psychiatric beds only, the district of Ferrara has 30 beds (8.5 per 100,000) and the Middlesex and Elgin Counties have 89 beds (16.3 beds for 100,000). However, if we include the rehabilitation beds (that are located within a hospital setting in Ontario and in a residential community setting in Ferrara), we find that the district of Ferrara has 95 beds (27.0 per 100,000) and the Middlesex and Elgin Counties have 176 beds (32.3 per 100,000). As a result, the 10/100,000 beds rate for Italy reported by the OECD is an underestimate compared to figures reported for most other countries, as the beds included are hospital beds only.

Antidepressants versus placebo for panic disorder in adults

BACKGROUND

Panic disorder is characterised by repeated, unexpected panic attacks, which represent a discrete period of fear or anxiety that has a rapid onset, reaches a peak within 10 minutes, and in which at least four of 13 characteristic symptoms are experienced, including racing heart, chest pain, sweating, shaking, dizziness, flushing, stomach churning, faintness and breathlessness. It is common in the general population with a lifetime prevalence of 1% to 4%. The treatment of panic disorder includes psychological and pharmacological interventions. Amongst pharmacological agents, the National Institute for Health and Care Excellence (NICE) and the British Association for Psychopharmacology consider antidepressants, mainly selective serotonin reuptake inhibitors (SSRIs), as the first-line treatment for panic disorder, due to their more favourable adverse effect profile over monoamine oxidase inhibitors (MAOIs) and tricyclic antidepressants (TCAs). Several classes of antidepressants have been studied and compared, but it is still unclear which antidepressants have a more or less favourable profile in terms of effectiveness and acceptability in the treatment of this condition.

OBJECTIVES

To assess the effects of antidepressants for panic disorder in adults, specifically:1. to determine the efficacy of antidepressants in alleviating symptoms of panic disorder, with or without agoraphobia, in comparison to placebo;2. to review the acceptability of antidepressants in panic disorder, with or without agoraphobia, in comparison with placebo; and3. to investigate the adverse effects of antidepressants in panic disorder, with or without agoraphobia, including the general prevalence of adverse effects, compared to placebo.

SEARCH METHODS

We searched the Cochrane Common Mental Disorders' (CCMD) Specialised Register, and CENTRAL, MEDLINE, EMBASE and PsycINFO up to May 2017. We handsearched reference lists of relevant papers and previous systematic reviews.

SELECTION CRITERIA

All double-blind, randomised, controlled trials (RCTs) allocating adults with panic disorder to antidepressants or placebo.

DATA COLLECTION AND ANALYSIS

Two review authors independently checked eligibility and extracted data using a standard form. We entered data into Review Manager 5 using a double-check procedure. Information extracted included study characteristics, participant characteristics, intervention details and settings. Primary outcomes included failure to respond, measured by a range of response scales, and treatment acceptability, measured by total number of dropouts for any reason. Secondary outcomes included failure to remit, panic symptom scales, frequency of panic attacks, agoraphobia, general anxiety, depression, social functioning, quality of life and patient satisfaction, measured by various scales as defined in individual studies. We used GRADE to assess the quality of the evidence for each outcome MAIN RESULTS: Forty-one unique RCTs including 9377 participants overall, of whom we included 8252 in the 49 placebo-controlled arms of interest (antidepressant as monotherapy and placebo alone) in this review. The majority of studies were of moderate to low quality due to inconsistency, imprecision and unclear risk of selection and performance bias.We found low-quality evidence that revealed a benefit for antidepressants as a group in comparison with placebo in terms of efficacy measured as failure to respond (risk ratio (RR) 0.72, 95% confidence interval (CI) 0.66 to 0.79; participants = 6500; studies = 30). The magnitude of effect corresponds to a number needed to treat for an additional beneficial outcome (NNTB) of 7 (95% CI 6 to 9): that means seven people would need to be treated with antidepressants in order for one to benefit. We observed the same finding when classes of antidepressants were compared with placebo.Moderate-quality evidence suggested a benefit for antidepressants compared to placebo when looking at number of dropouts due to any cause (RR 0.88, 95% CI 0.81 to 0.97; participants = 7850; studies = 30). The magnitude of effect corresponds to a NNTB of 27 (95% CI 17 to 105); treating 27 people will result in one person fewer dropping out. Considering antidepressant classes, TCAs showed a benefit over placebo, while for SSRIs and serotonin-norepinephrine reuptake inhibitor (SNRIs) we observed no difference.When looking at dropouts due to adverse effects, which can be considered as a measure of tolerability, we found moderate-quality evidence showing that antidepressants as a whole are less well tolerated than placebo. In particular, TCAs and SSRIs produced more dropouts due to adverse effects in comparison with placebo, while the confidence interval for SNRI, noradrenergic reuptake inhibitors (NRI) and other antidepressants were wide and included the possibility of no difference.

AUTHORS' CONCLUSIONS

The identified studies comprehensively address the objectives of the present review.Based on these results, antidepressants may be more effective than placebo in treating panic disorder. Efficacy can be quantified as a NNTB of 7, implying that seven people need to be treated with antidepressants in order for one to benefit. Antidepressants may also have benefit in comparison with placebo in terms of number of dropouts, but a less favourable profile in terms of dropout due to adverse effects. However, the tolerability profile varied between different classes of antidepressants.The choice of whether antidepressants should be prescribed in clinical practice cannot be made on the basis of this review.Limitations in results include funding of some studies by pharmaceutical companies, and only assessing short-term outcomes.Data from the present review will be included in a network meta-analysis of psychopharmacological treatment in panic disorder, which will hopefully provide further useful information on this issue.

Vortioxetine for depression in adults

BACKGROUND

Major depressive disorder is a common mental disorder affecting a person's mind, behaviour and body. It is expressed as a variety of symptoms and is associated with substantial impairment. Despite a range of pharmacological and non-pharmacological treatment options, there is still room for improvement of the pharmacological treatment of depression in terms of efficacy and tolerability. The latest available antidepressant is vortioxetine. It is assumed that vortioxetine's antidepressant action is related to a direct modulation of serotonergic receptor activity and inhibition of the serotonin transporter. The mechanism of action is not fully understood, but it is claimed to be novel. Vortioxetine was placed in the category of "Other" antidepressants and may therefore provide an alternative to existing antidepressant drugs.

OBJECTIVES

To assess the efficacy and acceptability of vortioxetine compared with placebo and other antidepressant drugs in the treatment of acute depression in adults.

SEARCH METHODS

We searched Cochrane's Depression, Anxiety and Neurosis Review Group's Specialised Register to May 2016 without applying any restrictions to date, language or publication status. We checked reference lists of relevant studies and reviews, regulatory agency reports and trial databases.

SELECTION CRITERIA

We included randomised controlled trials comparing the efficacy, tolerability, or both of vortioxetine versus placebo or any other antidepressant agent in the treatment of acute depression in adults.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected the studies and extracted data. We extracted data on study characteristics, participant characteristics, intervention details and outcome measures in terms of efficacy, acceptability and tolerability. We analysed intention-to-treat (ITT) data only and used risk ratios (RR) as effect sizes for dichotomous data and mean differences (MD) for continuous data with 95% confidence intervals (CI). Meta-analyses used random-effects models.

MAIN RESULTS

We included 15 studies (7746 participants) in this review. Seven studies were placebo controlled; eight studies compared vortioxetine to serotonin-norepinephrine reuptake inhibitors (SNRIs). We were unable to identify any study that compared vortioxetine to antidepressant drugs from other classes, such as selective serotonin reuptake inhibitors (SSRIs).Vortioxetine may be more effective than placebo across the three efficacy outcomes: response (Mantel-Haenszel RR 1.35, 95% CI 1.22 to 1.49; 14 studies, 6220 participants), remission (RR 1.32, 95% CI 1.15 to 1.53; 14 studies, 6220 participants) and depressive symptoms measured using the Montgomery-Åsberg Depression Scale (MADRS) (score range: 0 to 34; higher score means worse outcome: MD -2.94, 95% CI -4.07 to -1.80; 14 studies, 5566 participants). The quality of the evidence was low for response and remission and very low for depressive symptoms. We found no evidence of a difference in total dropout rates (RR 1.05, 95% CI 0.93 to 1.19; 14 studies, 6220 participants). More participants discontinued vortioxetine than placebo because of adverse effects (RR 1.41, 95% CI 1.09 to 1.81; 14 studies, 6220 participants) but fewer discontinued due to inefficacy (RR 0.56, 95% CI 0.34 to 0.90, P = 0.02; 14 studies, 6220 participants). The quality of the evidence for dropouts was moderate.The subgroup and sensitivity analyses did not reveal factors that significantly influenced the results.In comparison with other antidepressants, very low-quality evidence from eight studies showed no clinically significant difference between vortioxetine and SNRIs as a class for response (RR 0.91, 95% CI 0.82 to 1.00; 3159 participants) or remission (RR 0.89, 95% CI 0.77 to 1.03; 3155 participants). There was a small difference favouring SNRIs for depressive symptom scores on the MADRS (MD 1.52, 95% CI 0.50 to 2.53; 8 studies, 2807 participants). Very low quality evidence from eight studies (3159 participants) showed no significant differences between vortioxetine and the SNRIs as a class for total dropout rates (RR 0.89, 95% CI 0.73 to 1.08), dropouts due to adverse events (RR 0.74, 95% CI 0.51 to 1.08) and dropouts due to inefficacy (RR 1.52, 95% CI 0.70 to 3.30).Against individual antidepressants, analyses suggested that vortioxetine may be less effective than duloxetine in terms of response rates (RR 0.86, 95% CI 0.79 to 0.94; 6 studies, 2392 participants) and depressive symptoms scores on the MADRS scale (MD 1.99, 95% CI 1.15 to 2.83; 6 studies; 2106 participants). Against venlafaxine, meta-analysis of two studies found no statistically significant differences (response: RR 1.03, 95% CI 0.85 to 1.25; 767 participants; depressive symptom scores: MD 0.02, 95% CI -2.49 to 2.54; 701 participants). In terms of number of participants reporting at least one adverse effect (tolerability), vortioxetine was better than the SNRIs as a class (RR 0.90, 95% CI 0.86 to 0.94; 8 studies, 3134 participants) and duloxetine (RR 0.89, 95% CI 0.84 to 0.95; 6 studies; 2376 participants). However, the sensitivity analysis casts some doubts on this result, as only two studies used comparable dosing.We judged none of the studies to have a high risk of bias for any domain, but we rated all studies to have an unclear risk of bias of selective reporting and other biases.

AUTHORS' CONCLUSIONS

The place of vortioxetine in the treatment of acute depression is unclear. Our analyses showed vortioxetine may be more effective than placebo in terms of response, remission and depressive symptoms, but the clinical relevance of these effects is uncertain. Furthermore, the quality of evidence to support these findings was generally low. In comparison to SNRIs, we found no advantage for vortioxetine. Vortioxetine was less effective than duloxetine, but fewer people reported adverse effects when treated with vortioxetine compared to duloxetine. However, these findings are uncertain and not well supported by evidence. A major limitation of the current evidence is the lack of comparisons with the SSRIs, which are usually recommended as first-line treatments for acute depression. Studies with direct comparisons to SSRIs are needed to address this gap and may be supplemented by network meta-analyses to define the role of vortioxetine in the treatment of depression.

Antidepressants and benzodiazepines for panic disorder in adults

BACKGROUND

A panic attack is a discrete period of fear or anxiety that has a rapid onset, reaches a peak within 10 minutes and in which at least four of 13 characteristic symptoms are experienced, including racing heart, chest pain, sweating, shaking, dizziness, flushing, stomach churning, faintness and breathlessness. Panic disorder is common in the general population with a lifetime prevalence of 1% to 4%. The treatment of panic disorder includes psychological and pharmacological interventions. Amongst pharmacological agents, antidepressants and benzodiazepines are the mainstay of treatment for panic disorder. Different classes of antidepressants have been compared; and the British Association for Psychopharmacology, and National Institute for Health and Care Excellence (NICE) consider antidepressants (mainly selective serotonin reuptake inhibitors (SSRIs)) as the first-line treatment for panic disorder, due to their more favourable adverse effect profile over monoamine oxidase inhibitors (MAOIs) and tricyclic antidepressants (TCAs). In addition to antidepressants, benzodiazepines are widely prescribed for the treatment of panic disorder.

OBJECTIVES

To assess the evidence for the effects of antidepressants and benzodiazepines for panic disorder in adults.

SEARCH METHODS

The Specialised Register of the Cochrane Common Mental Disorders Group (CCMDCTR) to 11 September 2015. This register includes relevant randomised controlled trials from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (1950-), Embase (1974-) and PsycINFO (1967-). Reference lists of relevant papers and previous systematic reviews were handsearched. We contacted experts in this field for supplemental data.

SELECTION CRITERIA

All double-blind randomised controlled trials allocating adult patients with panic disorder to antidepressants or benzodiazepines versus any other active treatment with antidepressants or benzodiazepines.

DATA COLLECTION AND ANALYSIS

Two review authors independently checked eligibility and extracted data using a standard form. Data were entered in RevMan 5.3 using a double-check procedure. Information extracted included study characteristics, participant characteristics, intervention details, settings and outcome measures in terms of efficacy, acceptability and tolerability.

MAIN RESULTS

Thirty-five studies, including 6785 participants overall (of which 5365 in the arms of interest (antidepressant and benzodiazepines as monotherapy)) were included in this review; however, since studies addressed many different comparisons, only a few trials provided data for primary outcomes. We found low-quality evidence suggesting no difference between antidepressants and benzodiazepines in terms of response rate (risk ratio (RR) 0.99, 95% confidence interval (CI) 0.67 to 1.47; participants = 215; studies = 2). Very low-quality evidence suggested a benefit for benzodiazepines compared to antidepressants in terms of dropouts due to any cause, even if confidence interval (CI) ranges from almost no difference to benefit with benzodiazepines (RR 1.64, 95% CI 1.03 to 2.63; participants = 1449; studies = 7). We found some evidence suggesting that serotonin reuptake inhibitors (SSRIs) are better tolerated than TCAs (when looking at the number of patients experiencing adverse effects). We failed to find clinically significant differences between individual benzodiazepines. The majority of studies did not report details on random sequence generation and allocation concealment; similarly, no details were provided about strategies to ensure blinding. The study protocol was not available for almost all studies so it is difficult to make a judgment on the possibility of outcome reporting bias. Information on adverse effects was very limited.

AUTHORS' CONCLUSIONS

The identified studies are not sufficient to comprehensively address the objectives of the present review. The majority of studies enrolled a small number of participants and did not provide data for all the outcomes specified in the protocol. For these reasons most of the analyses were underpowered and this limits the overall completeness of evidence. In general, based on the results of the current review, the possible role of antidepressants and benzodiazepines should be assessed by the clinician on an individual basis. The choice of which antidepressant and/or benzodiazepine is prescribed can not be made on the basis of this review only, and should be based on evidence of antidepressants and benzodiazepines efficacy and tolerability, including data from placebo-controlled studies, as a whole. Data on long-term tolerability issues associated with antidepressants and benzodiazepines exposure should also be carefully considered.The present review highlights the need for further higher-quality studies comparing antidepressants with benzodiazepines, which should be conducted with high-methodological standards and including pragmatic outcome measures to provide clinicians with useful and practical data. Data from the present review will be included in a network meta-analysis of psychopharmacological treatment in panic disorder, which will hopefully provide further useful information on this issue.

Azapirones versus placebo for panic disorder in adults

BACKGROUND

Panic disorder is common in the general population. It is often associated with other psychiatric disorders, such as drug dependence, major depression, bipolar disorder, social phobia, specific phobia and generalised anxiety disorder. Azapirones are a class of drugs used as anxiolytics. They are associated with less drowsiness, psychomotor impairment, alcohol potentiation and potential for addiction or abuse than benzodiazepines. However, azapirones are not widely used in the treatment of panic disorder and evidence for their efficacy is unclear. It is important to find out if azapirones are effective and acceptable in the treatment of panic disorder.

OBJECTIVES

To assess the effects of azapirones on panic disorder in adults, specifically:1. to determine the efficacy of azapirones in alleviating symptoms of panic disorder, with or without agoraphobia, in comparison with placebo;2. to review the acceptability of azapirones in panic disorder, with or without agoraphobia, in comparison with placebo; and3. to investigate adverse effects of azapirones in panic disorder with or without agoraphobia, including general prevalence of adverse effects, compared with placebo.

SEARCH METHODS

We searched the Cochrane Depression Anxiety and Neurosis Group Trials Specialised Register (CCDANCTR, search date: 10th January 2014), which includes relevant randomised controlled trials from The Cochrane Library (all years), MEDLINE (1950-), EMBASE (1974-), and PsycINFO (1967-).

SELECTION CRITERIA

Randomised controlled trials that compared azapirones with placebo for panic disorder in adults.

DATA COLLECTION AND ANALYSIS

Three review authors independently identified studies, assessed trial quality and extracted data. We contacted study authors for additional information.

MAIN RESULTS

Three studies involving 170 participants compared the azapirone buspirone with placebo. No study provided enough usable information on our primary efficacy outcome (response). For our primary acceptability outcome, moderate-quality evidence indicated that azapirones had lower acceptability than placebo: risk ratio (RR) for dropouts for any reason 2.13 (95% confidence interval (CI) 1.11 to 4.07; 3 studies, 170 participants. Evidence for secondary efficacy outcomes were of low quality. Results on efficacy between azapirone and placebo in terms of agoraphobia (standardised mean difference (SMD) -0.01, 95% CI -0.56 to 0.53; 1 study, 52 participants), general anxiety (mean difference (MD) -2.20, 95% CI -5.45 to 1.06; 2 studies, 115 participants) and depression (MD -1.80, 95% CI -5.60 to 2.00; 1 study, 52 participants) were uncertain. None of the studies provided information for the assessment of allocation concealment or sequence generation. Conflicts of interest were not explicitly expressed. The risk of attrition bias was rated high for all three studies. Information on adverse effects other than dropouts for any reason was insufficient to include in the analyses.

AUTHORS' CONCLUSIONS

The efficacy of azapirones is uncertain due to the lack of meta-analysable data for the primary outcome and low-quality evidence for secondary efficacy outcomes. A small amount of moderate-quality evidence suggested that the acceptability of azapirones for panic disorder was lower than for placebo. However, only trials of one azapirone (namely buspirone) were included in this review; this, combined with the small sample size, limits our conclusions. If further research is to be conducted, studies with larger sample sizes, with different azapirones and with less risk of bias are necessary to draw firm conclusions regarding azapirones for panic disorder.

Agomelatine versus other antidepressive agents for major depression

BACKGROUND

Major depressive disorder (MDD), or depression, is a syndrome characterised by a number of behavioural, cognitive and emotional features. It is most commonly associated with a sad or depressed mood, a reduced capacity to feel pleasure, feelings of hopelessness, loss of energy, altered sleep patterns, weight fluctuations, difficulty in concentrating and suicidal ideation. There is a need for more effective and better tolerated antidepressants to combat this condition. Agomelatine was recently added to the list of available antidepressant drugs; it is a novel antidepressant that works on melatonergic (MT1 and MT2), 5-HT 2B and 5-HT2C receptors. Because the mechanism of action is claimed to be novel, it may provide a useful, alternative pharmacological strategy to existing antidepressant drugs.

OBJECTIVES

The objective of this review was 1) to determine the efficacy of agomelatine in alleviating acute symptoms of major depressive disorder in comparison with other antidepressants, 2) to review the acceptability of agomelatine in comparison with other antidepressant drugs, and, 3) to investigate the adverse effects of agomelatine, including the general prevalence of side effects in adults.

SEARCH METHODS

We searched the Cochrane Collaboration's Depression, Anxiety and Neurosis Review Group's Specialised Register (CCDANCTR) to 31 July 2013. The CCDANCTR includes relevant randomised controlled trials from the following bibliographic databases: CENTRAL (the Cochrane Central Register of Controlled Trials) (all years), EMBASE (1974 onwards), MEDLINE (1950 onwards) and PsycINFO (1967 onwards). We checked reference lists of relevant studies together with reviews and regulatory agency reports. No restrictions on date, language or publication status were applied to the search. Servier Laboratories (developers of agomelatine) and other experts in the field were contacted for supplemental data.

SELECTION CRITERIA

Randomised controlled trials allocating adult participants with major depression to agomelatine versus any other antidepressive agent.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data and a double-entry procedure was employed. Information extracted included study characteristics, participant characteristics, intervention details and outcome measures in terms of efficacy, acceptability and tolerability.

MAIN RESULTS

A total of 13 studies (4495 participants) were included in this review. Agomelatine was compared to selective serotonin reuptake inhibitors (SSRIs), namely paroxetine, fluoxetine, sertraline, escitalopram, and to the serotonin-norepinephrine reuptake inhibitor (SNRI), venlafaxine. Participants were followed up for six to 12 weeks. Agomelatine did not show any advantage or disadvantage over the other antidepressants for our primary outcome, response to treatment (risk ratio (RR) 1.01, 95% confidence interval (CI) 0.95 to 1.08, P value 0.75 compared to SSRIs, and RR 1.06; 95% CI 0.98 to 1.16, P value 0.16 compared to venlafaxine). Also, agomelatine showed no advantage or disadvantage over other antidepressants for remission (RR 0.83; 95% CI 0.68 to 1.01, P value 0.07 compared to SSRIs, and RR 1.08; 95% CI 0.94 to 1.24, P value 0.73 compared to venlafaxine). Overall, agomelatine appeared to be better tolerated than venlafaxine in terms of lower rates of drop outs (RR 0.40; 95% CI 0.24 to 0.67, P value 0.0005), and showed the same level of tolerability as SSRIs (RR 0.95; 95% CI 0.83 to 1.09, P value 0.44). Agomelatine induced a lower rate of dizziness than venlafaxine (RR 0.19, 95% CI 0.06 to 0.64, P value 0.007).With regard to the quality of the body of evidence, there was a moderate risk of bias for all outcomes, due to the number of included unpublished studies. There was some heterogeneity, particularly between published and unpublished studies. The included studies were conducted in inpatient and outpatient settings, thus limiting the generalisability of the results to primary care settings. With regard to precision, the efficacy outcomes were precise, but the tolerability outcomes were mostly imprecise. Publication bias was variable and depended on the outcome of the trial. Our review included unpublished studies, and we think that this reduced the impact of publication bias. The overall methodological quality of the studies was not very good. Almost all of the studies were sponsored by the pharmaceutical company that manufactures agomelatine (Servier), and some of these were unpublished. Attempts to contact the pharmaceutical company Servier for additional information on all unpublished studies were unsuccessful.

AUTHORS' CONCLUSIONS

Agomelatine did not seem to provide a significant advantage in efficacy over other antidepressive agents for the acute-phase treatment of major depression. Agomelatine was better tolerated than paroxetine and venlafaxine in terms of overall side effects, and fewer participants treated with agomelatine dropped out of the trials due to side effects compared to sertraline and venlafaxine, but data were limited because the number of included studies was small. We found evidence that compared agomelatine with only a small number of other active antidepressive agents, and there were only a few trials for each comparison, which limits the generalisability of the results. Moreover, the overall methodological quality of the studies was low, and, therefore, no firm conclusions can be drawn concerning the efficacy and tolerability of agomelatine.

Agomelatine efficacy and acceptability revisited: systematic review and meta-analysis of published and unpublished randomised trials

BACKGROUND

Agomelatine is a novel antidepressant drug with narrative, non-systematic reviews making claims of efficacy.

AIMS

The present study systematically reviewed published and unpublished evidence of the acute and long-term efficacy and acceptability of agomelatine compared with placebo in the treatment of major depression.

METHOD

Randomised controlled trials comparing agomelatine with placebo in the treatment of unipolar major depression were systematically reviewed. Primary outcomes were (a) Hamilton Rating Scale for Depression (HRSD) score at the end of treatment (short-term studies) and (b) number of relapses (long-term studies).

RESULTS

Meta-analyses included 10 acute-phase and 3 relapse prevention studies. Seven of the included studies were unpublished. Acute treatment with agomelatine was associated with a statistically significant superiority over placebo of -1.51 HRSD points (99% CI -2.29 to -0.73, nine studies). Data extracted from three relapse prevention studies failed to show significant effects of agomelatine over placebo (relative risk 0.78, 99% CI 0.41-1.48). Secondary efficacy analyses showed a significant advantage of agomelatine over placebo in terms of response (with no effect for remission). None of the negative trials were published and conflicting results between published and unpublished studies were observed.

CONCLUSIONS

We found evidence suggesting that a clinically important difference between agomelatine and placebo in patients with unipolar major depression is unlikely. There was evidence of substantial publication bias.

Sales of antidepressants, suicides and hospital admissions for depression in Veneto Region, Italy, from 2000 to 2005: an ecological study

BACKGROUND

Increased prescription of antidepressants has been consistently associated with a decrease in suicide rates in several countries. The aim of this study is to explore antidepressant consumption, suicide rates and admission for depression in the Veneto Region, Italy, in order to see whether the same pattern could be detected.

METHODS

Data from the Italian Ministry of Health (admissions for depression), the Pharmacy Service of a Local Health Unit (antidepressant prescribing) and from the Epidemiological System of the Veneto region (suicide rates) were collected from 2000 to 2005 for the Veneto region.

RESULTS

Suicide rates did not show any marked increase but were stable in males and females. Antidepressant prescribing increased exponentially over the period examined, whilst admissions for depression markedly decreased. The trend for an exponential increase in antidepressant prescribing in the Veneto region is shared with other countries and locales.

CONCLUSIONS

It is possible that the increase in antidepressant prescribing might be associated with earlier treatment of depression, thus decreasing the likelihood of aggravation of depression.

Antidepressant prescribing and suicides in emilia-romagna region (Italy) from 1999 to 2008: an ecological study

Anti-depressant (AD) prescribing rose in several countries worldwide over the last 20 years. Some concerns have been raised over the fact that AD use, mainly Selective Serotonin Reuptake Inhibitors (SSRI) may increase the risk of suicide. AD consumption and suicide rates data in Emilia-Romagna region, Italy have been extracted from regional government databases on AD prescribing and suicide rates, from 1999 to 2008. A statistical model using ordinary least squares linear regression was employed. The overall suicide rates decreased during the period under examination, in spite of the observed exponential increase in use of ADs. Despite the doubling in prescribing of SSRI and newer ADs in recent years, there continues to be no negative impact on suicide rates in Emilia Romagna.

Hydroxyzine for generalised anxiety disorder

BACKGROUND

Generalised anxiety disorder (GAD) is a common chronic long-term psychiatric disorder, particularly frequent in primary care. There are several treatment options available, both non-pharmacological (i.e. cognitive behavioral therapy) and pharmacological. Among the pharmacological interventions, antidepressants, buspirone and benzodiazepines (BDZs) have been studied in GAD. Hydroxyzine is an anti-histamine medication which has been used in the treatment of anxiety.

OBJECTIVES

1. To determine the efficacy of hydroxyzine in comparison with placebo or any other active agent in alleviating the acute symptoms of GAD. 2. To review acceptability of treatment with hydroxyzine in comparison with placebo or any other active agent. 3. To investigate the adverse effects of hydroxyzine in comparison with other active agents.

SEARCH STRATEGY

The Cochrane Depression, Anxiety and Neurosis Group's controlled trial registers (CCDANCTR-Studies and CCDANCTR-References) were searched on 1 March 2010. The author team ran complementary searches on MEDLINE, CINAHL and PsycINFO and checked reference lists of included studies, previous systematic reviews and major textbooks of anxiety disorders. Personal communication with pharmaceutical companies and experts in the field was also undertaken.

SELECTION CRITERIA

Randomised controlled trials allocating patients with GAD to hydroxyzine versus placebo and/or any other anxiolytic agent.

DATA COLLECTION AND ANALYSIS

Two authors independently extracted data. Information extracted included study characteristics, participant characteristics, intervention details and outcome measures in terms of efficacy (such as the number of patients who responded to treatment or remitted), acceptability (the number of patients who failed to complete the study) and tolerability (side effect profile).

MAIN RESULTS

The search yielded 39 studies. We included five studies in the review with a total of 884 participants. We excluded 31 studies and designated three as awaiting assessment. The data from the included studies provide some evidence that hydroxyzine is more effective than placebo for GAD (odds ratio (OR) 0.30, 95% CI 0.15 to 0.58) and that it is also acceptable/tolerable (OR 1.00, 95% CI 0.63 to 1.58) (OR 1.49, 95% CI 0.92 to 2.40). Compared to other anxiolytic agents (benzodiazepines and buspirone), hydroxyzine was equivalent in terms of efficacy, acceptability and tolerability (hydroxyzine vs chloridiazepoxide: OR 0.75, 95% CI 0.35 to 1.62; hydroxyzine vs buspirone efficacy OR 0.76, 95% CI 0.40 to 1.42). In terms of side effects, hydroxyzine was associated with a higher rate of sleepiness/drowsiness than the active comparators (OR 1.74, 95% CI 0.86 to 3.53). There was, however, a high risk of bias in the included studies.

AUTHORS' CONCLUSIONS

The included studies did not report on all the outcomes that were pre-specified in the protocol for this review. Even though more effective than placebo, due to the high risk of bias of the included studies, the small number of studies and the overall small sample size, it is not possible to recommend hydroxyzine as a reliable first-line treatment in GAD.

Suicide in Italian children and adolescents

BACKGROUND

Data and statistics on suicide mortality in several countries have been published and discussed over the last few decades but gaps in knowledge are present in the epidemiology of suicide among Italian youths.

METHODS

Suicide mortality data for the years 1973-2002 were obtained from the Italian Central Institute of Statistics (ISTAT). Age-standardized mortality rates were calculated and examined for trends over time.

RESULTS

During the last 3 decades the Italian population's overall suicide rate increased slightly from 67.8 per million in 1973 to 76.7 in 2002. Suicide rates were higher in males than females (2.8:1) and in Northern compared to Southern Italy. Suicide rates increased with age from 4.4 per million for children 10-14 years old to 25.8 (15-19 years) and 95.6 (> or = 20 years). The major increase over time was observed for 15-19 year old males.

LIMITATIONS

Routine suicide mortality data have several weaknesses; these are especially, related to the level of accuracy in the certification of violent causes of death.

CONCLUSION

A national research programme to study suicidal behaviour and risk factors in children and adolescents is essential. The permanent monitoring of the situation, exploring gender and interpersonal issues with the aim to plan protective initiatives in an appropriate manner, is also fundamental.

Amitriptyline for depression

BACKGROUND

For many years amitriptyline has been considered one of the reference compounds for the pharmacological treatment of depression. However, new tricyclic drugs, heterocyclic compounds and selective serotonin reuptake inhibitors have been introduced on the market with the claim of a more favourable tolerability/efficacy profile.

OBJECTIVES

The aim of the present systematic review was to investigate the tolerability and efficacy of amitriptyline in comparison with the other tricyclic/heterocyclic antidepressants and with the selective serotonin reuptake inhibitors.

SEARCH STRATEGY

The Cochrane Collaboration Depression, Anxiety and Neurosis Controlled Trials Register (CCDANCTR-Studies) was searched on 28-11-2005. Reference lists of all included studies were checked.

SELECTION CRITERIA

Only randomised controlled trials were included. Study participants were of either sex and any age with a primary diagnosis of depression. Included trials compared amitriptyline with another tricyclic/heterocyclic antidepressant or with one of the selective serotonin reuptake inhibitors.

DATA COLLECTION AND ANALYSIS

Data were extracted using a standardised form. The number of patients undergoing the randomisation procedure, the number of patients who completed the study and the number of improved patients were extracted. In addition, group mean scores at the end of the trial on Hamilton Depression Scale or any other depression scale were extracted. In the tolerability analysis, the number of patients failing to complete the study and the number of patients complaining of side-effects were extracted.

MAIN RESULTS

A total number of 194 studies were included in the review. The estimate of the overall odds ratio (OR) for responders showed that more subjects responded to amitriptyline in comparison with the control antidepressant group (OR 1.12 to 95% confidence interval (CI) 1.02 to 1.23, number needed to treat to benefit (NNTB) = 50). The estimate of the efficacy of amitriptyline and control agents on a continuous outcome revealed an effect size which also significantly favoured amitriptyline (Standardised Mean Difference (SMD) 0.13, 95% CI 0.04 to 0.23). Whilst these differences are statistically significant, their clinical significance is less clear. When the efficacy analysis was stratified by drug class, no difference in outcome emerged between amitriptyline and either tricyclic or selective serotonin reuptake inhibitor comparators. The dropout rate in patients taking amitriptyline and control agents was similar; however, the estimate of the proportion of patients who experienced side-effects significantly favoured control agents in comparison with amitriptyline (OR 0.66, 95% CI 0.59 to 0.74). When the tolerability analysis was stratified by drug class, the dropout rate in patients taking amitriptyline and the selective serotonin reuptake inhibitors significantly favoured the latter (OR 0.84, 95% CI 0.75 to 0.95, number needed to treat to harm (NNTH) = 40). When the responder analysis was stratified by study setting amitriptyline was more effective than control antidepressants in inpatients (OR 1.22, 95% CI 1.04 to 1.42, NNTB = 24), but not in outpatients (OR 1.01, 95%CI 0.88 to 1.17, NNTB = 200).

AUTHORS' CONCLUSIONS

This present systematic review indicates that amitriptyline is at least as efficacious as other tricyclics or newer compounds. However, the burden of side-effects in patients receiving it was greater. In comparison with selective serotonin reuptake inhibitors amitriptyline was less well tolerated, and although counterbalanced by a higher proportion of responders, the difference was not statistically significant.

Admissions for personality disorders in Italy from 1988 to 1998

BACKGROUND

Personality disorders affect a substantial proportion of the population. It is unclear, however, whether the burden of personality disorders on modern mental health services has been increasing. To fill this gap, we analyzed trends in admissions for personality disorders in Italy from 1988 to 1998.

METHODS

We used the yearly data from the Italian Central Institute of Statistics to analyse trends in the total number of admissions for personality disorders and in the total number of first admissions for personality disorders.

RESULTS

The absolute number of admissions for personality disorders almost trebled from 1988 to 1998, as well as the proportion of all psychiatric admissions that were for personality disorders. Whilst there has been a marked increase in the absolute number of first admissions, the proportion of all first psychiatric admissions that were for personality disorders showed a steady but modest increase, from 5.7% to 7.6%.

CONCLUSION

In Italy, the burden of personality disorders on modern mental health services has been increasing. In terms of public health, these findings highlight the urgent need of developing policies to tackle the increasing demand of care of this difficult-to-treat patient population.

Antidepressant drug consumption and public health indicators in Italy, 1955 to 2000

OBJECTIVE

This study investigated the impact of the increasing consumption of selective serotonin reuptake inhibitors (SSRIs) and newer anti-depressants on the following public health indicators: (1) suicide rates, (2) proportion of completed suicides by poisoning with solid or liquid substances, and (3) hospital admissions for depression and proportion of admissions for depression that were first admissions.

METHOD

Data collected by IMS Health on antidepressants dispensed in Italy from 1983 to 2000 were obtained from the Italian Ministry of Health, while data on suicide deaths from 1955 to 2000 were obtained from the Italian National Institute of Statistics.

RESULTS

In Italy from 1983 to 2000, the use of tricyclic antidepressants remained substantially stable, and the use of SSRIs and newer agents dramatically increased. In contrast, suicide rates for males decreased from 1955 to 1974 and subsequently increased, reaching a peak in 1985 and then declining. In females, suicide rates remained substantially stable until 1978. A subsequent increase occurred up to 1985, followed by a steady decline. Suicide by poisoning using solids or liquids dropped by nearly 50% from 1986 to 2000. Admissions to the hospital for depression showed an erratic pattern; however, no decline was observed. No change was observed in the rate of first admissions for depression.

CONCLUSION

Despite a reduction in suicides by poisoning using solids or liquids, the analysis of long-term trends in suicide did not suggest that increases in antidepressant prescribing lie behind recent reductions in population suicides. Furthermore, in Italy, newer antidepressants had no impact on the total number of admissions for depression or on the proportion of all admissions that were first admissions.

Amitriptyline for Inpatients and SSRIs for Outpatients with Depression? Systematic Review and Meta-Regression Analysis

BACKGROUND

Although the selective serotonin reuptake inhibitors (SSRIs) are widely used as first-line agents in depression, amitriptyline, a reference tricyclic (TCA) agent, has the edge in terms of efficacy over control antidepressants (ADs), but it is not clear whether this advantage can be attributed to a more favourable profile in inpatients, but not in outpatients, with depression. The aim of this study was to investigate the contribution of study setting on outcome in clinical trials comparing amitriptyline with any other AD.

METHODS

A systematic review and meta-regression analysis of amitryptiline randomised clinical trials was carried out. The electronic search yielded 181 randomised clinical trials, 47% enrolling inpatients and 53% outpatients with depression.

RESULTS

Both on a dichotomous and continuous out-come, amitriptyline was more effective than control agents in in-patients [Peto odds ratio (OR): 1.22, 95%, Confidence Interval (CI): 1.04, 1.42; Standardised Mean Difference (SMD): 0.28, 95 %,Cl: 0.08, 0.46], but not in outpatients (Peto OR: 1.01, 95%, CI: 0.88,1.17; SMD: 0.10,95% CI: -0.02,0.23). Among inpatients amitriptyline was significantly more effective than TCA and nonsignificantly more effective than the SSRIs. Among outpatients no statistically significant differences emerged between amitriptyline and TCA and between amitriptyline and the SSRIs. Amitriptylinewas less well tolerated than control agents in outpatients (Peto OR: 0.90, 95%, CI: 0.81, 0.99), but not in inpatients (Peto OR:1.09, 95% CI: 0.95, 1.25).

CONCLUSIONS

These data suggest that a reasonable approach could be the first-line prescription of newer agents in the routine outpatient care of depressive subjects, and the use of amitriptyline in inpatients with severe depression.

The Rivermead Behavioural Memory Test can predict social functioning among schizophrenic patients treated with clozapine

OBJECTIVE The aim of this study was to find out whether clinical symptoms, such as positive and negative symptoms, or cognitive problems, such as impairment in memory, are predictive of social outcome among patients with schizophrenia and treated with clozapine in the long-term. METHODS Twelve subjects with a DSM-III-R diagnosis of schizophrenia treated with clozapine were recruited from an inpatient rehabilitation psychiatry unit. Subjects were assessed at baseline, and 6, 12 and 24 months, using symptoms measures, the Social Behaviour Scale (SBS) and the Rivermead Behavioural Memory Test (RBMT), which tests episodic memory. Three multivariate stepwise regression models were created with SBS at 6, 12 and 24 months score as dependent variable, and the other measures at baseline as independent variables. RESULTS The only significant contribution on social functioning in each model was made by the RBMT, which was therefore the only significant predictor of social functioning in all models. CONCLUSIONS The authors discuss the importance of episodic memory in the prediction of social functioning.

Amitriptyline versus other types of pharmacotherapy for depression

BACKGROUND

For many years amitriptyline has been considered one of the reference compounds for the pharmacological treatment of depression. However, new tricyclic drugs, heterocyclic compounds and the selective serotonin reuptake inhibitors have been introduced on the market with the claim of a more favourable tolerability/efficacy profile.

OBJECTIVES

The aim of the present systematic review was to investigate the tolerability and efficacy of amitriptyline in comparison with the other tricyclic/heterocyclic antidepressants and with the selective serotonin reuptake inhibitors.

SEARCH STRATEGY

The Cochrane Collaboration Depression, Anxiety and Neurosis Controlled Trials Register (2002-3) and the Cochrane Central Register of Controlled Trials (CENTRAL) were searched. Key journals and conference abstracts were handsearched. Pharmaceutical companies were contacted for information on unpublished materials.

SELECTION CRITERIA

Only randomised controlled trials were included. Study participants were of either sex and any age with a primary diagnosis of depression. Included trials compared amitriptyline with another tricyclic/heterocyclic antidepressant or with one of the selective serotonin reuptake inhibitors.

DATA COLLECTION AND ANALYSIS

Data were extracted using a standardised form. The number of patients undergoing the randomisation procedure, the number of patients who completed the study and the number of improved patients were extracted. In addition, group mean scores at the end of the trial on Hamilton Depression Scale or any other depression scale were extracted. In the tolerability analysis, the number of patients failing to complete the study and the number of patients complaining of side-effects was extracted.

MAIN RESULTS

The estimate of the overall odds ratio for responders showed that more subjects responded to amitriptyline in comparison with the control antidepressant group (odds ratio 1.12, 95% confidence interval 1.01, 1.23, number needed to treat 50). The estimate of the efficacy of amitriptyline and control agents on a continuous outcome revealed an effect size which also significantly favoured amitriptyline (Standardised Mean Difference 0.13, 95% confidence interval 0.04, 0.23). Whilst these differences are statistically significant, their clinical significance is less clear. When the efficacy analysis was stratified by drug class, no difference in outcome emerged between amitriptyline and either tricyclic or selective serotonin reuptake inhibitor comparators. The dropout rate in patients taking amitriptyline and control agents was similar; however, the estimate of the proportion of patients who experienced side-effects significantly favoured control agents in comparison with amitriptyline (odds ratio 0.63, 95% confidence interval 0.56, 0.71). When the tolerability analysis was stratified by drug class, the dropout rate in patients taking amitriptyline and the selective serotonin reuptake inhibitors significantly favoured the latter (odds ratio 0.84, 95% confidence interval 0.75,0.95, number needed to harm 40). When the responder analysis was stratified by study setting amitriptyline was more effective than control ADs in inpatients (odds ratio 1.22, 95% confidence interval 1.04, 1.42, number needed to treat 24), but not in outpatients (odds ratio 1.01, 95% confidence interval 0.88, 1.17, number needed to treat = 200).

REVIEWER'S CONCLUSIONS

This present systematic review indicates that amitriptyline is at least as efficacious as other tricyclics or newer compounds. However, the burden of side-effects in patients receiving it was greater. In comparison with the selective serotonin reuptake inhibitors amitriptyline was less well tolerated, and although counterbalanced by a higher proportion of responders, the difference was not statistically significant.

Prescribing second-generation antipsychotics and the evolving standard of care in Italy

The present study was carried out to investigate the routine use of second-generation antipsychotic drugs in the Italian psychiatric care system. Seven outpatient psychiatric services enrolled a consecutive case series of patients who were being treated, or had started treatment, with clozapine, olanzapine, risperidone, or quetiapine. Information on sociodemographic and clinical variables, current psychotropic drug use, side-effects and past use of typical drugs was collected. In addition, patient symptoms and functional status were evaluated by the Health of the Nation Outcome Scale. Patients receiving off-label prescribing of second-generation antipsychotics were identified. A total of 209 patients were collected. In comparison with patients receiving other second-generation antipsychotics, living in residential facilities, unemployment, long psychiatric histories, and problems with activities of daily living and living conditions were more common in clozapine-treated patients. Nearly 80 % of patients receiving clozapine had schizophrenia compared to less than 50 % of those receiving other second-generation antipsychotics. Overall, 109 patients (52 %) received off-label prescriptions of second-generation antipsychotic drugs. This survey indicates that clozapine was mostly reserved for severe cases and poor responders; the high rate of off-label prescriptions highlights the gap existing between recommendations derived from randomised clinical trials and the current use of drugs.

Update of suicide trends in Italy from 1986 to 1996

BACKGROUND

In some Western countries increasing suicide rates have been observed among males, especially young men, with a decline of female suicides. The present study analysed age-specific and age-standardised suicide rates in Italy.

METHOD

From 1986 to 1996 national statistics on numbers of suicides in each sex and age group were examined.

RESULTS

Overall, suicides have remained substantially stable from 1986 to 1996. Among males over 45 years of age rates progressively decreased, and among subjects below 15 years rates remained stable. In the 15-24 and 25-44 age groups rates progressively rose: an overall increase of 2.76/100,000 and 1.60/100,000 was recorded, respectively. Among females over 45 years of age suicide rates progressively decreased, while rates in the other age groups remained fairly stable.

CONCLUSION

The present analysis documents a rise in suicides among young men, and highlights the need for age-specific suicide prevention programmes.

[A systemic review of the European Agency for the evaluation of medicinal products (EMEA) recommendations on the conduct of clinical trials in psychiatry]

OBJECTIVE

This article critically reviews the European Agency for the Evaluation of Medicinal Products (EMEA) recommendations on the conduct of clinical trials in psychiatry. The EMEA is a regulatory body which provides the institutions of the European Community with the best possible scientific advice on the quality, safety, and efficacy of medicinal products.

METHOD

Systematic review of recommendations, guide-lines and official documents available in the EMEA web site.

RESULTS

Out of nearly 400 documents, we identified 4 documents on the conduct of clinical trials in specific psychiatric disorders and 5 on the use of placebo or active comparator in evaluating a new drug's efficacy and on methodological issues in establishing difference and equivalence of effect. The EMEA recommends clinical trials to detect a difference between the compound under investigation and placebo, and to assess at least non-inferiority against an active comparator. A placebo arm is intended to validate the study. The EMEA supports the use of placebo only when there is no serious risk for the patient. In schizophrenia, depression and bipolar disorder the Agency suggests that a three-arm study is the design of choice, to demonstrate superiority against placebo and a similar balance against an active comparator.

CONCLUSIONS

Despite the many effective therapeutic options available for the pharmacological management of psychiatric disorders, the EMEA regulatory process still relies on the demonstration of efficacy in absolute terms, against a placebo. We discuss this position and put at issue the possibility of developing a new generation of trials to demonstrate superiority of effect of new compounds over reference ones.

[A rare case of cholostasis from tuberculotic infiltration of Vater's ampulla]

A rare case of cholostasis from tuberculotic infiltration of the Vater's ampulla is described and was observed in a patient 83 years old. The diagnosis was made at operation after a positive radiologic evidence of an oddian stenosis with cholostasis and an important dilatation of the bile ducts. The surgical operation and the antituberculotic therapy allowed to overcome the cholostasis and the specific infection of the patient and to improve his quality of life and to prolong his survival. The description of this case, in our opinion, is important to underline that tuberculosis of the biliary papilla should be kept in mind as a possible, but rare cause, of obstructive jaundice, during the differential diagnosis.
