RESUMO
BACKGROUND: Mesothelioma is an aggressive thoracic tumour with a poor prognosis. The only treatment that extends survival is chemotherapy. However, in the UK, up to 50% of patients who are suitable for chemotherapy choose not to receive it, opting for active symptom control instead. The aim of this prospective, single-centre observational study was to describe the characteristics of patients who chose active symptom control over chemotherapy and explore their reasons for doing so. METHODS: Two hundred consecutive patients with mesothelioma from one UK centre were included. Eligibility for chemotherapy and choice of first-line treatment were recorded prospectively. Patient characteristics and outcomes were compared using descriptive statistics, regression analysis and survival analysis. Reasons for choosing active symptom control over chemotherapy were extracted, retrospectively. RESULTS: People who chose active symptom control were older, more likely to be female and had worse performance statuses than patients who received front-line chemotherapy. Concern over side effects, the modest survival benefit and previous adverse experiences with chemotherapy were reported as reasons for the decision. Median survival was 13.9 months in the chemotherapy group compared with 6.7 months in the active symptom control group. CONCLUSIONS: This is the first study to describe the characteristics of patients with mesothelioma who chose active symptom control over chemotherapy, in the front-line setting. Important differences were seen between this group and patients who received chemotherapy, although confounding is likely to have affected some outcomes. Future research could use qualitative methods to explore patients' reasons for choosing active symptom control, and to further elucidate the decision-making process.

Patients with type 2 diabetes (T2DM) and inadequate glycaemic control on combination metformin (MET) and sulphonylurea (SU) were enrolled in a 24-week, double-blind, randomized, placebo-controlled study with a 28-week extension. The five-dimension EuroQol questionnaire (EQ-5D), SHIELD Weight Questionnaire-9 (WQ-9), Impact of Weight on Quality of Life-Lite (IWQOL-Lite) questionnaire and the Diabetes Treatment Satisfaction Questionnaire (DTSQ) were used to evaluate health status and health-related quality of life (HRQoL) at baseline and week 52. Patients with dapagliflozin 10 mg + MET + SU (n = 108) were compared with patients treated with placebo + MET + SU (n = 108), using a repeated-measures mixed model. EQ-5D visual analogue scale scores, IWQOL-Lite and DTSQ scores improved in the dapagliflozin and placebo groups from baseline to week 52; however, there was no significant difference between groups (p > 0.20). EQ-5D index scores remained the same from baseline to week 52 for dapagliflozin and placebo (p = 0.54). A numerically greater proportion of the dapagliflozin group reported improvement in all nine SHIELD WQ-9 items compared with placebo, and the difference was statistically significant for physical health (p = 0.017). Over 52 weeks of therapy, patients maintained their health status and HRQoL when dapagliflozin was added to the treatment.

OBJECTIVES: This study aimed to assess the effect of multivitamin use during the pill-free interval on the continuation rate and side effects of combined oral contraceptives (COCs) within the first few cycles of use. METHODS: In this trial, 332 women presenting to public health centres in an Iranian city each received a COC pack containing 21 pills and were randomised to one of three groups: two of the groups also received 42 multivitamin pills or 42 placebo pills to be taken once a day for 7 days before starting COCs and again during the 7-day pill-free interval for five cycles, while the third group received no multivitamin or placebo pills with their COCs. The groups were compared using Cox regression and χ(2) tests. RESULTS: There were no losses to follow-up. Continuation rates at the sixth cycle were 88% for the multivitamin group, 75% for the placebo group and 67% for the no intervention group. Compared with the multivitamin group, the six-cycle discontinuation rate was significantly higher in the placebo group (hazard ratio [HR] 2.26, 95% confidence interval [CI] 1.15-4.45; p = 0.019) and no intervention group (HR 3.15, 95% CI 1.66-5.99; p < 0.001). Nausea, mood changes, weight gain and breast tenderness were significantly less common in the multivitamin group than in the other groups in all cycles, and spotting/irregular bleeding and dizziness were significantly less common in most of the second, third and sixth cycle follow-up. CONCLUSIONS: Multivitamin supplements could significantly reduce the side effects of COCs in the initial cycles and improve continuation rates. However, the study limitations do not allow for any definite conclusion for their use in clinical practice, especially in communities rich in nutrients.

BACKGROUND: Older people often have multimorbidity requiring a complex regime of medications, which may change following hospital discharge, thus presenting new challenges. The experiences of older people, who manage their own medications, in particular following hospital discharge, have rarely been studied. AIM: This study investigates the experiences of older people with multimorbidity taking multiple medications after hospital discharge and how they cope with medication-taking. METHOD: A qualitative-descriptive approach with ten interviews was chosen. The data were coded openly into two groups according to Saldaña (2013). RESULTS: It is important for older people, in spite of their multimorbidity, to maintain their independence and maintain responsibility for taking their medications. Routines are developed from taking medications over many years and the new medications are easily integrated. Unclear information by the medical staff and the inability of the older people to obtain the medications after discharge may lead to mistakes or interruptions in the drug therapy at home. The key person for this group is the general practitioner, even concerning the drug therapy initiated in hospital. CONCLUSION: It is advisable to adapt discharge education to the needs of older people, especially with regard to their drug therapy, to its integration into their daily routine, and to any possible shortcomings in their medication management.

BACKGROUND: Little is known about how people living with human immunodeficiency virus (HIV) experience malaria and the concomitant use of anti-malarial treatments with anti-retrovirals (ARVs). An understanding of how patients make sense of these experiences is important to consider in planning and supporting the clinical management and treatment for co-infected individuals. METHODS: A qualitative study was conducted in Tanzania alongside a clinical trial of concomitant treatment for HIV and malaria co-infection. Focus group discussions were held with people receiving treatment for HIV and/or malaria, and in-depth interviews with health workers responsible for HIV care and members of the clinical trial team. Data were analysed inductively to identify themes and develop theoretical narratives. RESULTS: Results suggest that people living with HIV perceived malaria to be more harmful to them due to their compromised immune status but saw the disease as unavoidable. For those enrolled in the clinical controlled study, taking anti-malarials together with ARVs was largely seen as unproblematic, with health workers' advice and endorsement of concomitant drug taking influential in reported adherence. However, perceptions of drug strength appeared to compel some people not enrolled in the clinical study to take the drugs at separate times to avoid anticipated harm to the body. CONCLUSIONS: Management of HIV and malaria concurrently often requires individuals to cross the domains of different disease programmes. In the context of a trial concerned with both diseases, patients experienced the support of clinicians in guiding and reassuring them about when and how to take drugs concomitantly. This points towards the need to continue to strive for integrated care for patients with HIV.

BACKGROUND: Hepatitis C virus (HCV) infections are a severe burden on public health worldwide, causing mortality rates triple that of the general population. Since 2011, for both therapy-naive and therapy-experienced genotype 1 patients, the first generation of direct acting antivirals (DAAs), i.e., the protease-inhibitors (PI) telaprevir and boceprevir have been added to existing dual therapies. The therapeutic effect of the resulting triple therapy is striking; however, treatment regimens are complex and commonly cause side effects. Little is known of how patients implement therapy in their daily lives, or of how they deal with these effects.This study aims to describe HCV patients' experiences with protease-inhibitor-based triple therapy and their support needs. METHODS: A qualitative design was used. Patients from three outpatient clinics, with ongoing, completed or discontinued PI treatment experience were recruited using a maximum variation sampling approach. Open-ended interviews were conducted and analyzed using thematic analysis according to Braun & Clarke (Qual Res Psychol 3:77-101, 2006). RESULTS: Thirteen patients participated in the interviews. All described themselves as highly motivated to undergo treatment, since they saw the new therapy as a "real chance" for a cure. However, all later described the therapy period as a struggle. The constitutive theme-"Fighting an uphill battle"- describes the common existential experience of and negative consequences of coping with side effects. The processes that fostered this common experience followed three sub-themes: "encountering surprises", "dealing with disruption" and "reaching the limits of systems". CONCLUSION: HCV patients undergoing outpatient protease-inhibitor-based triple therapy need systematic support in symptom management. This will require specially trained professionals to advise and support them and their families, and to provide rapid responses to their needs throughout this complex course of therapy. As the generation of DAAs for all genotypes, are expected to have less severe side effects, and many HCV patients require treatment, this knowledge can improve treatment support tremendously, especially for patients who are quite difficult to treat. Furthermore, these findings are helpful to illustrate development in HCV treatment.

All currently available antipsychotic drugs are the dopamine D2 receptor antagonists and are capable of producing extrapyramidal side-effects (EPS). Anticholinergic drugs are primarily used to treat EPS or prevent EPS induced by antipsychotics in the treatment of psychosis and schizophrenia. However, they can cause a variety of distressing peripheral side-effects (e.g. dry mouth, urinary disturbances, and constipation) and central adverse effects (e.g. cognitive impairment, worsening of tardive dyskinesia, and delirium). Disturbances in cognitive abilities are cardinal features of schizophrenia from its earliest phases and account for much of the functional disability associated with the illness. It is likely that long-term concomitant administration of anticholinergics exacerbates the underlying cognitive impairment in patients with schizophrenia and subsequently affects patients' quality of life. Thus, current treatment guidelines for schizophrenia generally do not recommend the prophylactic and long-term use of anticholinergics. However, the high use of long-term anticholinergic drugs with antipsychotics has been identified as an important issue in the treatment of schizophrenia in several countries. To assess the benefits and limits of anticholinergic use in psychosis and schizophrenia, this article will provide a brief review of the pharmacology and clinical profiles of anticholinergic drugs and will focus on their effects on cognitive function in schizophrenia, particularly during the course of the early phase of the illness. In addition, we will address the effects of discontinuation of anticholinergics on cognitive function in patients with schizophrenia and provide a strategy for adjunctive anticholinergic use in patients treated with long-acting injectable antipsychotics.

Chronic heart failure (CHF) is a serious health problem today. Despite all advances in modern medicine, the high morbidity and mortality rates of CHF force physicians to search for new more effective methods for its control. At the same time, the fact that the designing of new effective medicaments is complex and expensive and that patients show low compliance with drug therapy increases the value of non-drug treatments for heart failure, such as patient education, higher treatment compliance, which make it possible to significantly enhance the efficiency of current combined drug therapy, to improve quality of life, and, possibly, to reduce future heart failure death rates.

BACKGROUND: Different patient groups are known to use herbal remedies and conventional drugs concomitantly (co-use). This poses a potential risk of herb-drug interaction through altering the drug's pharmacokinetics or pharmacodynamics. Little is known about co-use among patients in general practice. The primary aim of this study was to compare patients in general practice that co-use herbal remedies and conventional drugs with those who do not. The secondary aim was to register the herb-drug combinations with potential clinical relevant interactions among the co-users. METHOD: A questionnaire based cross-sectional study conducted in the autumn 2011 in a general practice office with four general practitioners (GPs) and one intern in Western Norway. Adults >18 years who came for an office visit were invited. The questionnaire asked about demographics, herbal use, conventional drug use and communication about herbal use. Multivariable logistic regression was used to compare co-users to the other patients. RESULTS: Of the 381 patients who completed the questionnaire, the prevalence of herbal use was 44%, with bilberry (41%), green tea (31%), garlic (27%), Aloe vera (26%) and echinacea (18%) as the most frequently used. Among those using conventional drugs regularly, 108 (45%) co-used herbs. Close to 40% of patients on anticoagulants co-used herbs, with garlic and bilberry as the most frequent herbs. Compared to all other patients, co-users had significantly (p < 0.05) increased odds to be female (adjOR 2.0), age above 70 years (adjOR 3.3), use herbs to treat an illness (adjOR 4.2), use two or more herbs (polyherbacy, adjOR 12.1) and having experienced adverse effects of herbal use (adjOR 37.5). Co-use was also associated with use of analgesics or dermatological drugs (adjOR 5.1 and 7.9 respectively). Three out of four patients did not discuss herbal use with any health care professional. CONCLUSION: A sizable proportion of the GP patients co-used herbs with conventional drugs, also combinations with reported interaction potential or additive effects like anticoagulants and garlic. The low disclosure of herbal use to their GP, polyherbacy and the risk of interactions in vulnerable groups like elderly and chronically ill patients, warrant increased awareness among GPs.

BACKGROUND: The progressive nature of type 2 diabetes necessitates exogenous insulin use for most patients; basal insulin plus oral anti-diabetes drugs (OADs) is a well-validated way to facilitate insulin initiation. The primary aim of this study was to explore insulin initiation strategies and outcomes for patients using insulin detemir or glargine plus oral anti-diabetes drugs. METHODS: LIGHT was a 3-month, longitudinal observational study conducted across 761 French centres in insulin-naïve type 2 diabetes patients managed under routine clinical care conditions, in either primary or secondary care. Endpoints included changes in HbA(1c) , fasting plasma glucose (FPG), rate of hypoglycaemia, weight, and adverse events. RESULTS: Most physicians initiated a basal analogue to improve glycaemic control (97%), with many delaying beginning treatment for several months (9 ± 9.0 months for general practitioners, 10.2 ± 16.2 months for specialists). Most patients continued oral anti-diabetes drug therapy (95%) and lifestyle measures (92%), with 2-3 blood glucose readings per day and follow-up telephone calls for dose optimization. Mean change in HbA(1c) from baseline was - 1.3%, and - 3.1 mmol/L for fasting plasma glucose (both p < 0.0001). Hypoglycaemia increased from 1.4 to 5.6 events/patient/year (p < 0.0001), and weight decreased on average by 0.5 kg with detemir, with no change in glargine. Most patients (93%) reported being satisfied or very satisfied with their insulin. CONCLUSIONS: Insulin initiation with detemir or glargine can be successfully managed in both primary and secondary care; the benefits of basal analogues (once-daily dosing, low rates of hypoglycaemia compared with neutral protamine Hagedorn) may have contributed to patient acceptance of the regimen.

High rates of attrition have been reported in randomized controlled trials of patients with severe psychiatric illness, including psychotic depression (MDpsy). The purpose of this study is to examine factors associated with overall attrition and with subtypes of attrition in the Study of the Pharmacotherapy of Psychotic Depression (STOP-PD). Secondary analysis of data collected in a multi-site, randomized, placebo-controlled trial. Clinical services of academic hospitals. Participants comprised 259 persons with MDpsy, aged 18-93 years. The intervention consisted of the random allocation to 12 weeks of treatment of either olanzapine plus sertraline or olanzapine plus placebo. Demographic and clinical variables associated with overall non-completion and sub-types of non-completion of randomized treatment. One hundred and seventeen (45.2%) subjects did not complete 12 weeks of randomized treatment. In a logistic regression analysis, inpatient entry status, olanzapine monotherapy, and higher cumulative medical burden were statistically significant independent predictors of overall non-completion. In a multinomial logistic regression model that examined predictors of subtypes of non-completion, subjects who entered the study as an inpatient were less likely to complete because of inadequate efficacy as determined by the investigator, and older subjects were less likely to complete because of poorer tolerability. Subjects who were assigned to olanzapine monotherapy, younger subjects, and subjects who entered the study as inpatients were less likely to complete because of reasons other than efficacy or tolerability. Understanding factors that contribute to premature discontinuation in studies of MDpsy, and to the specific reasons for attrition, has the potential to improve the management of this disorder, as well as improve the design of future clinical trials of MDpsy.

BACKGROUND: The Bipolar Comprehensive Outcomes Study (BCOS) is a 2-year, prospective, non-interventional, observational study designed to explore the clinical and functional outcomes associated with 'real-world' treatment of participants with bipolar I or schizoaffective disorder. All participants received treatment as usual. There was no study medication. METHODS: Participants prescribed either conventional mood stabilizers (CMS; n = 155) alone, or olanzapine with, or without, CMS (olanzapine ± CMS; n = 84) were assessed every 3 months using several measures, including the Young Mania Rating Scale, 21-item Hamilton Depression Rating Scale, Clinical Global Impressions Scale - Bipolar Version, and the EuroQol Instrument. This paper reports 24-month longitudinal clinical, pharmacological, functional, and socioeconomic data. RESULTS: On average, participants were 42 (range 18 to 79) years of age, 58%; were female, and 73%; had a diagnosis of bipolar I. Polypharmacy was the usual approach to pharmacological treatment; participants took a median of 5 different psychotropic medications over the course of the study, and spent a median proportion of time of 100%; of the study on mood stabilizers, 90%; on antipsychotics, 9%; on antidepressants, and 5%; on benzodiazepines/hypnotics. By 24 months, the majority of participants had achieved both symptomatic and syndromal remission of both mania and depression. Symptomatic relapse rates were similar for both the CMS alone (65%;) and the olanzapine ± CMS (61%;) cohorts. CONCLUSIONS: Participants with bipolar I or schizoaffective disorder in this study were receiving complex medication treatments that were often discordant with recommendations made in contemporary major treatment guidelines. The majority of study participants demonstrated some clinical and functional improvements, but not all achieved remission of symptoms or syndrome.

BACKGROUND: Curcumin is the active principle of Curcuma longa, one of the widely used components in the traditional system of medicine in India. Despite its efficacy in experimental studies aiming at neuronal disorders like depression, curcu-min's poor water solubility challenges the production of therapeutic formulations. This study investigates the antidepressant-like activity of novel water-soluble curcumin formulations, dispensed in three different concentrations. Further, the study comparatively evaluates St. John's wort (SJW), another herbal preparation. METHODS: These compounds were evaluated in the forced swimming test in mice, and the corresponding changes in the neurotransmitter levels were measured. RESULTS: Three water-soluble curcumin formulations, C-5, C-20 and C-50 (50-200 mg/kg p.o.) decreased the immobility period, and increased serotonin and dopamine levels in the brain tissues. A subeffective dose (50 mg/kg) of these formulations enhanced the antidepressant-like effect of classical antidepressants with varied mechanisms of action. In addition, an SJW dose of 25 mg/kg showed a significant antidepressant-like effect in all the behavioral studies and also significantly increased brain neurotransmitter levels, especially that of serotonin. The effects produced by C-5 were comparable with those of SJW and fluoxetine, respectively. CONCLUSION: In all these observations, the water-soluble formulations showed a significant antidepressant-like effect, including enhancement of neurotransmitter levels as compared to the similar dose of a conventional curcumin preparation. Thus, these formulations may be used as a novel treatment option in the management of mental depression.

In short-term efficacy studies, coprescription of a benzodiazepine improves first-month adherence and response to antidepressant treatment. We used Veterans Health Administration data to examine the impact of coprescribed benzodiazepines on initial antidepressant adherence in routine clinical practice and the risks of long-term benzodiazepine use, abuse, and dependence. Our study population was 43,915 Veterans Health Administration patients diagnosed with depression and started on an antidepressant between October 2006 and September 2007. Using logistic regression, adjusting for demographic and clinical covariates, we predicted the likelihood that patients received antidepressant treatment for an adequate duration (90 days), with our primary independent variable of interest being receipt of a benzodiazepine on the same day as the start of the antidepressant. We also assessed the frequency and characteristics of patients whose benzodiazepine use persisted for 1 year or who were diagnosed with anxiolytic abuse or dependence after receiving combined treatment. The adjusted probability of receiving antidepressant treatment of adequate duration was 42.4% for patients who received a benzodiazepine with their initial antidepressant compared with 39.3% for patients initially treated with an antidepressant alone (P < 0.001). Among patients who received combined treatment, 14.1% subsequently used benzodiazepines for at least 1 year, and 0.7% were diagnosed with anxiolytic abuse or dependence. Anxiolytic abuse or dependence, but not long-term benzodiazepine use, was associated with other substance use disorders. These findings should be considered by clinicians when assessing the individual risks and benefits of combining a benzodiazepine with antidepressant treatment.

The sequential parallel comparison design (SPCD) has been proposed to increase the likelihood of success of clinical trials in therapeutic areas where high-placebo response is a concern. The trial is run in two stages, and subjects are randomized into three groups: (i) placebo in both stages; (ii) placebo in the first stage and drug in the second stage; and (iii) drug in both stages. We consider the case of binary response data (response/no response). In the SPCD, all first-stage and second-stage data from placebo subjects who failed to respond in the first stage of the trial are utilized in the efficacy analysis. We develop 1 and 2 degree of freedom score tests for treatment effect in the SPCD. We give formulae for asymptotic power and for sample size computations and evaluate their accuracy via simulation studies. We compute the optimal allocation ratio between drug and placebo in stage 1 for the SPCD to determine from a theoretical viewpoint whether a single-stage design, a two-stage design with placebo only in the first stage, or a two-stage design is the best design for a given set of response rates. As response rates are not known before the trial, a two-stage approach with allocation to active drug in both stages is a robust design choice.

Attitudes and beliefs about antiretroviral therapy (ART) may affect sexual risk behaviors among the general population in sub-Saharan Africa. We performed a cross-sectional population-based study in Kisumu, Kenya to test this hypothesis in October 2006. A total of 1655 participants were interviewed regarding attitudes and beliefs about ART and their sexual risk behaviors. The majority of participants, (71%) men and (70%) women, had heard of ART. Of these, 20% of men and 29% of women believed ART cures HIV. Among women, an attitude that "HIV is more controllable now that ART is available" was associated with sex with a non-spousal partner, increased lifetime number of sexual partners as well as a younger age at sexual debut. No significant associations with this factor were found among men. The belief that "ART cures HIV" was associated with younger age of sexual debut among women. The same belief was associated with an increased likelihood of exchanging sex for money/gifts and decreased likelihood of condom use at last sex among men. These findings were most significant for people aged 15-29 years. In high HIV seroprevalence populations with expanding access to ART, prevention programs must ensure their content counteracts misconceptions of ART in order to reduce high risk sexual behaviors, especially among youth.

This paper reviews the literature on various mental health problems and their impact on adherence to antiretroviral therapy (ART). Depression, anxiety disorders, and disorders related to substance abuse were identified as key role-players influencing adherence. The severity of symptoms related to these disorders was found to be inversely related to ART adherence, with the possible exception of post-traumatic stress disorder (PTSD). PTSD was found to have both positive and negative implications for adherence, with severity of symptoms ranging from health-protective concern to disabling distress. Possible solutions aimed at addressing the adverse effects of mental health problems on adherence are discussed. Routine screening in ART settings is suggested in settings where follow-up of positive screen scores are possible, along with the necessary interventions to resolve the disorder of concern. Suggested interventions include utilising psychotherapeutic treatment, both in isolation and in conjunction with medication, to address mental health problems. Furthermore, finding effective ways of marshalling social support is recommended for ensuring optimal adherence, and possibly mitigating the adverse effects of mental health problems. Further research is needed to find feasible ways of identifying, assessing and treating patients with mental health problems in resource-constrained settings where HIV prevalence is highest.

BACKGROUND: In this chart review, we attempted to evaluate the benefits of adding aripiprazole in veterans with military-related PTSD and comorbid depression, who had been minimally or partially responsive to their existing medications. METHODS: A retrospective chart review of patients who received an open-label, flexible-dose, 12- week course of adjunctive aripiprazole was conducted in 27 military veterans meeting DSM-IV criteria for PTSD and comorbid major depression. Concomitant psychiatric medications continued unchanged, except for other antipsychotics which were discontinued prior to initiating aripiprazole. The primary outcome variable was a change from baseline in the PTSD checklist-military version (PCL-M) and the Beck Depression Inventory (BDI-II). RESULTS: PTSD severity (Total PCL scores) decreased from 56.11 at baseline to 46.85 at 12-weeks (p < 0.0001 from Wilcoxon signed rank test) and the depression severity decreased from 30.44 at baseline to 20.67 at 12-weeks (p < 0.0001 from Wilcoxon signed rank test). Thirty seven percent (10/27) were considered responders, as defined by a decrease in total PCL scores of at least 20 percent and 19% (5/27) were considered as responders as defined by a decrease in total BDI score of at least 50%. CONCLUSIONS: The addition of aripiprazole contributed to a reduction in both PTSD and depression symptomatology in a population that has traditionally demonstrated poor pharmacological response. Further investigations, including double-blind, placebo-controlled studies, are essential to confirm and further demonstrate the benefit of aripiprazole augmentation in the treatment of military related PTSD.

BACKGROUND AND OBJECTIVES: Buprenorphine and methadone are widely used for the treatment of opioid dependence, but their diversion and/or misuse are frequent. In principle, buprenorphine/naloxone combination therapy should be associated with a lower frequency of drug abuse/misuse than methadone. This study assessed the efficacy of the substitution of buprenorphine treatment with the buprenorphine/naloxone combination in opioid-dependent patients. MATERIAL AND METHODS: 3812 drug-addicted outpatients selected from 10 Italian Public Services for Addiction (Ser.T.) centres in Naples (Italy) were enrolled: 3105 (81.5%) were treated with methadone and 707 (18.5%) with buprenorphine. The buprenorphine treatment was switched to buprenorphine/naloxone (4:1), and the patients were followed for about 1 year. The number of subjects still on treatment after 1 year, their status according to social, educational and toxicologic (assessed by a urine toxicology test) parameters were assessed. RESULTS: 1 year after the therapy switch, the number of patients still on treatment was similarly reduced with methadone (2883; -7.5%) and buprenorphine/naloxone (632; -10.6%; p=0.369). However, in patients treated with buprenorphine/naloxone, a significant improvement was reported in social life status (63% versus 39% of the buprenorphine/naloxone and methadone treated subjects, respectively, were married/cohabiting p<0.001), in the educational level (43% of buprenorphine/naloxone treated versus 32% of the methadone treated subjects obtained at least a high school certificate, p<0.001) and in the toxicological conditions (53% of buprenorphine/naloxone treated subject versus 30% of methadone treated individuals had opioid- and cocaine- negative urine tests, p<0.001). DISCUSSION: These preliminary data suggest that buprenorphine/naloxone treatment of opioid dependence reduces the percentage of treated subjects similarly to methadone, and is associated with an improvement in social life, educational and toxicological conditions, compared with methadone treatment. However, we cannot exclude a selection bias, i.e. patients who were more likely to stabilize their opiate dependence switched to buprenorphine/naloxone.

INTRODUCTION: Practice guidelines recommend maintaining antidepressant treatment for a long duration (at least six months) after symptomatic improvement. In practice, treatment effectiveness is often jeopardized by non-persistence. METHOD: A retrospective cohort study was conducted on a standard sample representative of the members of the French universal health insurance system database, in order to assess antidepressant treatment duration in a real-life setting. 35,053 outpatients who initiated an antidepressant treatment in 2005-2006 were followed up until 2007. Incident antidepressant treatment was defined as no delivery of antidepressant in the six months prior to treatment initiation. Persistence to treatment was defined as antidepressant treatment duration of six months or more. Multivariate analyses were conducted in order to identify characteristics associated with persistence to treatment. RESULTS: Most antidepressant treatments (n = 28,674; 81.8%) lasted for less than six months and more than half for 28 days at most (n = 20,377; 58.1%). Persistence to treatment was associated with older age (OR 1,13; 95% CI 1.11-1.15), female gender (1.22; 1.15-1.30), chronic disease (1.21; 1.13-1.31), not being on welfare (0.67; 0.60-0.74) and coprescription of anxiolytics (0.36; 0.33-0.38), antipsychotics (0.39; 0.35-0.43) or mood-stabilizers (0.45; 0.39-0.53). Prescribers' specialty was also associated with persistence. Treatments prescribed by general practitioners were less likely to be continued than those prescribed by psychiatrists (1.65; 1.47-1.86). CONCLUSION: Non-persistence to antidepressant treatment is very frequent in France. Intervention programs aimed at increasing persistence should target physicians' training and patients' education.
