Predictors of antipsychotics switching among ambulatory patients with schizophrenia in Ethiopia: a multicenter hospital-based cross-sectional study

INTRODUCTION

A change of therapy from one to another antipsychotic medication is currently the main challenge of therapy. This study aimed to assess the prevalence of antipsychotic medication switches and determinants among patients with schizophrenia in Northwest Ethiopia.

METHODS

Multi-center hospital-based cross-sectional study was conducted at five Comprehensive Specialized Hospitals found in Northwest Ethiopia from April 30, 2021, to August 30, 2021. Data were extracted from both patients' medical charts and interviews. Data were entered into Epi-data software version 3.5.1 and exported to SPSS version 25.0 for analysis. A multivariable logistic regression model was fitted to identify factors associated with medication regimen switch. The level of significance of the study was kept at a p-value of 0.05 with a 95% confidence interval.

RESULT

A total of 414 patients are involved in the study, and 188 (45.5%) of patients switched antipsychotics within one year. The unavailability of the medication is the commonest reason for switching. Being male [AOR = 2.581, 95% CI (1.463, 4.552)], having relapse [AOR = 2.341,95% CI (1.169,4.687)], history of hospitalization in the past year [AOR = 3.00,95% CI (1.478,5.715)] and taking typical antipsychotics [AOR = 3.340, CI (1.76, 6.00)] had a significant association with antipsychotics switching.

CONCLUSIONS AND RECOMMENDATIONS

There is a high prevalence of antipsychotic switches among schizophrenia patients. Prescribers need to be careful while dosing, selecting, and switching antipsychotics, hence may help reduce discontinuation and unnecessary switch and thus achieve optimal clinical management.

Atypical Treatment Switches in Schizophrenia Patients: Drivers and Associated Outcomes

Objective

To describe and compare demographics and outcomes among patients with schizophrenia who have switched atypical treatments versus non-switchers.

Methods

Data were extracted from the Adelphi Schizophrenia Disease Specific Programme™ conducted from January to May 2014 in the United States. Participating physicians provided information on their next 10 consulting schizophrenia patients aged ≥ 18 years; the same patients were invited to voluntarily complete a patient self-completion form (PSC). Patients were considered switchers (S) or non-switchers (NS) based on their physician-provided treatment history. S were patients who had switched, stopped or added an atypical treatment within the last 2 years. NS had no treatment changes within the last 2 years or were receiving their first-line treatment (for ≥ 3 months). Demographics, clinical characteristics and outcomes among S and NS were compared using both descriptive and multivariate statistics.

Results

One-hundred fifty physicians provided data on 1003 patients with schizophrenia (395 S, 608 NS); 500 patients completed a PSC (170 S, 330 NS). When compared with NS, S were more likely to be unemployed (p=0.0060), have a caregiver (p<0.0001), have greater activity impairment as assessed by Work and Productivity Activity Impairment (p=0.0031), be hospitalized for schizophrenia (p<0.0001) and have had a greater mean number of hospitalizations in the last 12 months (p=0.0012). NS vs S were more likely to have much or very much improved illness (p<0.0001) and less severe disease (p<0.0001) as assessed by Clinical Global Impression.

Conclusion

Despite switching drugs, some schizophrenia patients continue to have high levels of disease burden, suggesting that currently available therapies are insufficiently effective in these patients.

Patterns of Care for Adolescent With Schizophrenia: A Delphi-Based Consensus Study

BACKGROUND

The current conceptualization of schizophrenia as neurodevelopmental disorder should lead to innovative public health policies in terms of a reorganization of the mental health care systems, particularly in the transition from adolescence to adulthood, to reduce personal, familiar, and social costs and burdens. The purpose of the project was to perform a survey among a panel of Italian schizophrenia experts, to share evidence-based information on adolescent schizophrenia and explore the degree of consensus among professionals in the following four macro-areas: early diagnosis; pharmacological treatment; health care system organization and transition process from adolescent to adulthood; and psychosocial interventions.

METHODS

The consensus process consisted of a two-step web-based Delphi method, which took place between June and November 2021. The survey was developed by a panel of four psychiatrists and four child neuropsychiatrists, identified as key opinion leaders (KOLs). The KOLs identified 21 statements involving a total of 70 items with a major need of clarification on early-onset schizophrenia (EOS). The survey was distributed to 86 specialists in psychiatry and child neuropsychiatry.

RESULTS

The results revealed a large agreement among the expert group on all the investigated areas of adolescent schizophrenia patterns of care and management. Consensus was ultimately reached for 67 items of the Delphi survey (95.7%), while negative consensus was reached for 2 items and no consensus was reached for 1 item.

CONCLUSIONS

Overall, results showed a significant gap between the acquired scientific knowledge and clinical practice. In this scenario, it should be necessary to plan specific initiatives at a multiple level, to edit recommendations on clinical decision-making, as well as to prompt changes at the political and organizational levels, also involving scientific societies, patients, and family associations, to overcome the barriers that delay the implementation process.

Switching Between Second-Generation Antipsychotics in Patients with Schizophrenia and Schizoaffective Disorder: 10-Year Cohort Study in Brazil

Objective: Switching between second-generation antipsychotics (SGAs) is a common clinical practice in the treatment of schizophrenia and schizoaffective disorders due to differences in the drugs’ tolerability and safety profiles as well as the challenge of obtaining an ideal response. However, the factors associated with SGA switching remain uncertain and related real-world data are scarce. The main objective was to identify the factors associated with the switching of SGAs in patients with schizophrenia or schizoaffective disorder.

Methods: We conducted a retrospective cohort study of outpatients with schizophrenia or schizoaffective disorder, who were aged ≥18 years and received a SGA (clozapine, olanzapine, risperidone, quetiapine or ziprasidone) from a Brazilian pharmaceutical assistance program for at least 3 months. We identified SGA users from 2008 to 2017 by using a national administrative database (Ambulatory Information System-SIA/SUS). The factors associated with the switches were evaluated by Cox proportional hazards regression and adjusted for sex and age; the confidence interval was set at 95% (95% CI).

Results: In total, 563,765 patients were included. Female sex, advanced age of ≥70 years, residence in the Brazilian northeast region, and the type of antipsychotic used were associated with an increased risk of switching (p < 0.001). The incidence of switching ranged from 37.6/100 person-years for clozapine users to 58.2/100 person-years for risperidone users. Compared to the adjusted hazard ratio, for clozapine users, the corresponding ratios for risperidone, ziprasidone, quetiapine and olanzapine were 1.59 (95% CI, 1.57–1.61), 1.41 (95% CI, 1.39–1.44), 1.25 (95% CI, 1.23–1.26) and 1.11 (95% CI, 1.10–1.12) respectively.

Conclusion: The groups most susceptible to SGA switching in real-life setting were older individuals, women, and those living in the Brazilian northeast region. Risperidone was associated with the highest risk of switching and as expected, clozapine was associated with the lowest risk of switching than that associated with the other SGAs.

Antipsychotic-induced tardive dyskinesia: update on epidemiology and management

PURPOSE OF REVIEW

To provide an update on the frequency of antipsychotic-induced tardive dyskinesia and its management in patients with schizophrenia spectrum disorders in studies published since the last systematic review in 2008.

RECENT FINDINGS

Recent data about antipsychotic-induced tardive dyskinesia in patients with schizophrenia underscore the superiority of newer generation antipsychotics (21%) over first-generation antipsychotics (30%) with respect to prevalence and incidence rates. Regarding recently tested management strategies, the new vesicular monoamine transporter 2 inhibitors valbenazine and deutetrabenazine have been found to be effective and may be considered as first-line pharmacotherapy for tardive dyskinesia. Owing to quality issues of randomized controlled trials and/or small sample sizes, limited and conflicting evidence remains for most treatment strategies.

SUMMARY

The reviewed literature reveals lower prevalence rates of antipsychotic-induced tardive dyskinesia in patients treated with newer generation compared with first-generation antipsychotics. The evidence of vesicular monoamine transporter 2 inhibitors as a first-line therapy for tardive dyskinesia is well supported by several controlled clinical trials.

Usefulness of Pharmacogenetic Analysis in Psychiatric Clinical Practice: A Case Report

There are many factors involved in the effectiveness and efficiency of psychiatric drug treatment. One of them is psychotropic drug metabolism, which takes place mostly in the liver through the P450 enzyme system. However, there are genotypic variants of this system’s enzymes that can directly affect both the efficacy and the onset of side effects of a given therapeutic regimen. These genotypic changes could partly explain the lack of efficacy of treatment in certain patients. We report the case of a patient diagnosed with bipolar type I disorder that presented multiple and frequent manic episodes in which the efficacy and tolerability of several pharmacological regimens with mood stabilizers and antipsychotics was scarce. The choice of medical treatment should be based on its efficacy and side effect profile. This decision can be made more accurately using the information provided by pharmacogenetic analysis. This case illustrates the importance of pharmacogenetic studies in clinical practice. The results of pharmacogenetic analysis helped to decide on a better treatment plan to achieve clinical improvement and reduce drug-induced adverse effects.

Management of asenapine treatment in clinical practice: Recommendations from a panel of experts

INTRODUCTION

The choice of an antipsychotic should be based on bipolar disorder (BD) symptoms and the particular needs of each patient, as well as the adverse events potentially associated with treatment. Asenapine is an atypical antipsychotic indicated for the management of type-I BD, with distinct pharmacokinetic and receptor affinity profiles.

MATERIAL AND METHODS

Recommendations document developed by a panel of experts with extensive experience in the use of asenapine in psychiatric care, including emergency department, hospital, and outpatient care. Recommendations were discussed in a single meeting and were based on both the clinical experience of the panel of experts and the empirical evidence provided in the scientific literature.

RESULTS

The present document describes the patient profile that best suits the pharmacodynamic characteristics of asenapine, as well as the advantages and limitations of the pharmacokinetics associated with the sublingual route. The document also addresses the main safety issues of asenapine and suggests interventions aimed at mitigating the most frequent adverse reactions associated with asenapine treatment. Finally, the article provides advice on dosing and overall management of asenapine treatment, including the combination with other treatments and the switch from other antipsychotics to asenapine.

CONCLUSIONS

In this recommendations document, we provide clinicians with guidance on the use of asenapine in real-life practice, including the identification of patients who best suit the characteristics of this antipsychotic.

Multidisciplinary consensus on the therapeutic recommendations for iatrogenic hyperprolactinemia secondary to antipsychotics

Hyperprolactinemia is an underappreciated/unknown adverse effects of antipsychotics. The consequences of hyperprolactinemia compromise therapeutic adherence and can be serious. We present the consensus recommendations made by a group of experts regarding the management of antipsychotic-induced hyperprolactinemia. The current consensus was developed in 3 phases: 1, review of the scientific literature; 2, subsequent round table discussion to attempt to reach a consensus among the experts; and 3, review by all of the authors of the final conclusions until reaching a complete consensus. We include recommendations on the appropriate time to act after hyperprolactinemia detection and discuss the evidence on available options: decreasing the dose of the antipsychotic drug, switching antipsychotics, adding aripiprazole, adding dopaminergic agonists, and other type of treatment. The consensus also included recommendations for some specific populations such as patients with a first psychotic episode and the pediatric-youth population, bipolar disorder, personality disorders and the elderly population.

Current Data on and Clinical Insights into the Treatment of First Episode Nonaffective Psychosis: A Comprehensive Review

Implementing the most suitable treatment strategies and making appropriate clinical decisions about individuals with a first episode of psychosis (FEP) is a complex and crucial task, with relevant impact in illness outcome. Treatment approaches in the early stages should go beyond choosing the right antipsychotic drug and should also address tractable factors influencing the risk of relapse. Effectiveness and likely metabolic and endocrine disturbances differ among second-generation antipsychotics (SGAs) and should guide the choice of the first-line treatment. Clinicians should be aware of the high risk of cardiovascular morbidity and mortality in schizophrenia patients, and therefore monitoring weight and metabolic changes across time is mandatory. Behavioral and counseling interventions might be partly effective in reducing weight gain and metabolic disturbances. Ziprasidone and aripiprazole have been described to be least commonly associated with weight gain or metabolic changes. In addition, some of the SGAs (risperidone, amisulpride, and paliperidone) have been associated with a significant increase of plasma prolactin levels. Overall, in cases of FEP, there should be a clear recommendation of using lower doses of the antipsychotic medication. If no or minimal clinical improvement is found after 2 weeks of treatment, such patients may benefit from a change or augmentation of treatment. Clinicians should provide accurate information to patients and relatives about the high risk of relapse if antipsychotics are discontinued, even if patients have been symptom free and functionally recovered on antipsychotic treatment for a lengthy period of time.

Antipsychotic switching in schizoaffective disorder: A systematic review

OBJECTIVES

To systematically review the evidence about the switching of antipsychotics in SZA in acute and maintenance treatment.

METHODS

A systematic review following the PRISMA statement identifying studies specifically conducted on, or including, SZA patients.

RESULTS

One analysis considered uniquely a SZA population, 13 more studies including an adequate SZA subsample were considered. Most of the studies were aimed at switching antipsychotic treatments to improve tolerability issues. Despite the absolute lack of trials specifically conducted on SZA populations, we found limited evidence on the use of aripiprazole, lurasidone, and, to a lesser extent, risperidone and ziprasidone as possible agents to substitute previous treatments whereas efficacy or, more frequently, tolerability issues arise. Evidence supports also the switch to risperidone long-acting injectable when the adherence to oral treatment may be a concern.

CONCLUSIONS

Antipsychotic switching in SZA is a neglected topic that would need better profiling. Clinicians should keep in mind the receptor binding characteristics of drugs in order to optimize transitions. Evidence supports the switch to aripiprazole and lurasidone, less strongly to risperidone and ziprasidone. The switch to risperidone long-acting injectable is supported, especially in patients with limited treatment adherence to oral therapy.

Cardiovascular and metabolic monitoring of children and adolescents on antipsychotic treatment: A cross-sectional descriptive study

BACKGROUND

Cardiovascular and metabolic monitoring of patients on antipsychotic medication is essential. This becomes more important in those of paediatric age, as they are more vulnerable, and also because prescriptions of this kind of drugs are still increasing.

AIM

To evaluate the monitoring of cardiovascular and metabolic risk factors in a group of children and young people on antipsychotic medication.

METHOD

A descriptive cross-sectional study was conducted in which a group of 220 patients aged 8-17 years, diagnosed with a mental disorder and on antipsychotic treatment. They were compared to a control group of 199 asthmatic patients not exposed to antipsychotic drugs. Data was extracted from the computerised clinical history ECAP in 2013.

RESULTS

The mean age of the children was 12 years (8-17). Risperidone (67%) was the most frequent treatment. The recording of Body Mass Index (BMI) and blood pressure (AP) was 50% in Mental Disorder (MD) patients. A higher number of cardiovascular monitoring physical parameters (weight, height, BMI and BP) were observed in the MD group compared to the control Asthma control group. Altogether, more physical parameters than biochemistry parameters were recorded.

CONCLUSIONS

This study shows that the recording of cardiovascular parameters and metabolic studies needs to be improved in children and adolescents on treatment with antipsychotics.

Diagnosis and management of breakthrough cancer pain: Have all the questions been resolved? A Delphi-based consensus assessment (DOIRON)

OBJECTIVE

To ascertain the level of agreement and achieve a consensus among cancer pain specialists in Spain with regard to the optimal definition, diagnosis, and management of breakthrough cancer pain (BTcP).

DESIGN

Two-round Delphi methodology survey (February-May 2013) using seven-point Likert scales (ranging from 1 "strongly disagree" to 7 "strongly agree") was carried out. Mean scores >5 or <3 indicated, respectively, agreement or disagreement. Scores from 3 to 5 indicated no consensus.

RESULTS

A total of 126 experienced specialists were surveyed. Response rates were 68 % in round 1 and 90 % in round 2. Agreement (mean Likert score) was strongest for the proposed BTcP definition (6.6), the use of oral (6.1), and intranasal (6.0) transmucosal fentanyl, the need for early assessment after BTcP treatment initiation, and the need to improve staff knowledge of BTcP. Broad agreement was also reached regarding the need to systematically screen all cancer patients for BTcP (5.9). Most respondents (82 %) considered strong opioids to be appropriate treatment. In contrast, no consensus was reached regarding strong opioid treatment for baseline pain as a prerequisite for BTcP diagnosis.

CONCLUSIONS

Consensus was strong for most treatment, and diagnostic aspects were evaluated in the study. However, several important issues remain unresolved, particularly whether the diagnostic criteria must include strong opioids for background pain. Nurses' awareness and understanding of BTcP was considered insufficient, and more training is needed in this area. Overall, agreement among specialists was good, but more work is needed to better define the optimal diagnostic features and treatments for this condition.

Antipsychotic use in children and adolescents: a 1-year follow-up study

OBJECTIVE

The objective of this study was to analyze the initial treatment with antipsychotics (APs) and its changes during the first year of treatment in patients visited in specialized child and adolescent psychiatry departments.

METHODS

Participants were 265 patients, aged 4 to 17 years, who attended consecutively at 4 different centers and were naive of AP or quasi-naive (less than 30 days since the beginning of AP treatment). Type of AP, dosage, and concomitant medication were registered at baseline, 1, 3, 6, and 12 months after beginning the treatment with AP.

RESULTS

At baseline, the patients' mean age was 14.4 (2.9) years, and 145 (54.7%) patients were males. Antipsychotics were more prescribed in the following: schizophrenia spectrum disorders (30.2%), disruptive behavior disorders (DBDs) (18.9%), bipolar disorders (14.3%), depressive disorders (12.8%), and eating disorders (11.7%). A total of 93.2% of the patients were on an off-label indication of AP. Risperidone was the AP most prescribed in all the assessments, but differences were observed in the type of AP according to diagnosis. Thus, risperidone was significantly most prescribed in patients with DBD and olanzapine was most prescribed in patients with eating disorders. Olanzapine and quetiapine were the second-generation APs (SGAs) most prescribed after risperidone, and haloperidol was the most prescribed first-generation AP. Up to 8.3% of patients during the follow-up were on AP polypharmacy. Almost 16% patients had a change in its AP treatment during the follow-up, and the main switch was from one SGA to another.

CONCLUSIONS

Second-generation APs were the APs most prescribed in our sample and approximately 93% of the patients used AP off-label. Risperidone was the most common AP used above all in patients with DBD, whereas olanzapine was most prescribed in patients with eating disorders. Antipsychotic polypharmacy and switch rates were low during the follow-up.

Antipsychotic switching in bipolar disorders: a systematic review

With the increasingly widespread use of antipsychotics in bipolar disorder (BD), switching among these agents and between antipsychotics and mood stabilizers has become more common, in particular, since the introduction of the novel atypical antipsychotics with mood stabilizer properties. This systematic review aims to provide a comprehensive update of the current literature in BD about the switching of antipsychotics, among them and between them and mood stabilizers, in acute and maintenance treatment. We conducted a comprehensive, computerized literature search using terms related to antipsychotic switching in BD in the PubMed/Medline, PsycINFO, CINAHL database; the Cochrane Library and; the Clinicaltrials.gov web up to January 9th, 2013 according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The search returned 4160 articles. After excluding duplications, reviews, case reports and studies that did not fulfil the selection criteria, 8 studies were included. Not only have few articles on antipsychotic switching been published but also recruitment in most studies included mixed samples of patients. In general, antipsychotic switching, regardless of the route of drug administration, was well tolerated and no interference was shown in antipsychotic effectiveness during the interchange of drugs. Metabolic improvement was perceived when the switch involved antipsychotics with a low metabolic risk profile. The evidence-base for antipsychotic switching in BD is scant, and little controlled data is available. Switch from quetiapine to lithium and from risperidone to olanzapine has proven successful. Switching to antipsychotics with low metabolic risk had some positive impact on several safety measures. In stabilized patients, the plateau cross-taper switch may be preferred.

Switching to ziprasidone in the clinical practice setting: an open-label study

OBJECTIVE

This observational study evaluates the long-term outcome of switching to ziprasidone in patients with schizophrenia in the clinical practice setting.

METHODS

Patients (208) with schizophrenia who had been switched to ziprasidone monotherapy due to partial response or tolerability problems were followed for 1 year. Efficacy was assessed at baseline and months 1, 3, and 12 with Brief Psychiatric Rating Scale (BPRS), Clinical Global Impression-severity (CGI-S), and CGI-improvement. Quality of life, functionality, and safety measures, including metabolic parameters, were also assessed; 195 subjects comprised the per protocol analysis population.

RESULTS

A reduction > or = 30% in BPRS total score was observed in 42.5% of the subjects. Mean scores of the BPRS (global and positive and negative clusters), CGI-S and CGI-I significantly decreased at endpoint (p < 0.001). Ziprasidone treatment was also associated with statistically significant improvements in the GAF, WHO-DAS-II, and SF-12. After 1-year follow-up, a mean weight decrease of -1.6 kg (p < 0.05) was observed. Mean levels of LDL cholesterol and triglycerides also decreased (p < 0.01) while HDL cholesterol levels increased (p < 0.05) at endpoint. No significant changes in mean glucose levels at study end were detected.

CONCLUSION

These findings suggest that switching to ziprasidone is effective and well tolerated in patients with schizophrenia requiring a change in antipsychotic medication.

Strategies for prevention and management of second generation antipsychotic-induced metabolic side effects

Preventing, minimizing and managing risks associated with second generation antipsychotic (SGA) use in patients with schizophrenia and other psychotic disorders is a priority for clinicians working with this population. Among these risks is metabolic syndrome. As this population exhibits increased rates of obesity, diabetes and atherogenic dyslipidemia compared to the general population, metabolic syndrome deserves serious consideration in patient care planning for managing risks. This article comprehensively reviews different strategies and recommendations for prevention and/or management of metabolic abnormalities associated with the use of SGAs. Baseline screening and follow-up metabolic monitoring as well as education and counseling on risk for SGA-induced weight gain and other metabolic abnormalities, physical activity and healthy diet for weight maintenance/loss should be promoted shortly after initiation of SGAs. In select patients, the clinician can consider simplifying the antipsychotic treatment regimen by switching to an agent with a lower propensity of metabolic side effects or possibly adding metformin for weight loss and glucose metabolism regulation in those experiencing a first episode of schizophrenia. Future research should focus on combinations of interventions and treatment modalities and exploration of novel interventions.
