Antipsychotic augmentation

BACKGROUND: Treatment effects of conventional approaches with antipsychotics or psychosocial interventions are limited when it comes to reducing negative and cognitive symptoms in schizophrenia. While there is emerging clinical evidence that new, augmented protocols based on theta-burst stimulation can increase rTMS efficacy dramatically in depression, data on similar augmented therapies are limited in schizophrenia. The different patterns of network impairments in subjects may underlie that some but not all patients responded to given stimulation locations...

Clozapine is the only approved drug for treatment-resistant schizophrenia, but the response to the drug is often inadequate. Augmentation with other antipsychotics, anticonvulsants, and antidepressants is recommended for such patients, but there is a lack of evidence regarding the most effective therapy. This network meta-analysis was conducted to evaluate the efficacy of pharmacological agents used in the augmentation strategies in patients who were partial/ non-responders to clozapine. Relevant data were extracted from 30 randomized controlled trials through searches of electronic databases (MEDLINE/PubMed, Embase, Cochrane, clinical trial registries)...

Irritable bowel syndrome are responsive to treatments using central neuromodulators. Central neuromodulators work by enhancing the synaptic transmission of 5-hydroxytryptamine, noradrenalin and dopamine, achieving a slower regulation or desensitization of their postsynaptic receptors. Central neuromodulators act on receptors along the brain-gut axis, so they are useful in treating psychiatric comorbidities, modifying gut motility, improving central downregulation of visceral signals and enhancing neurogenesis in patients with IBS...

BACKGROUND: A significant proportion of patients with a depressive disorder show resistance to pharmacological and psychotherapeutic antidepressant treatments. Electroconvulsive therapy (ECT) is still one of the most effective treatment methods, especially in the acute phase. In everyday clinical practice, this usually accompanies pharmacological treatment. It has been shown that pharmacological treatment following acute ECT treatment reduces the rate of relapses. However, the effect of various antidepressants (ADs) and antipsychotics (APs) on the effect during the course of ECT has rarely been investigated...

BACKGROUND: While skin picking disorder remains relatively common, it often does not present to psychiatry until significant morbidity or comorbidities are reached. It is described as recurrent picking of skin leading to skin lesions, with repeated attempts to decrease or stop skin picking. It is also often associated with significant distress or functional impairment. There has been limited research in this specific disorder and treatment efficacy has often been poor in severe cases...

Managing schizophrenia with clozapine poses a significant challenge due to prevalent therapeutic failures. The increasing interest in personalized medicine underscores the importance of integrating pharmacogenetic information for effective pharmacotherapeutic monitoring in patients. The objective of this study was to explore the correlation between DRD2 , HTR2A , SLC6A4 , CYP1A2 , and ABCB1 polymorphisms and clozapine response in 100 patients with Treatment-Resistant Schizophrenia. Different scales such as the Positive and Negative Syndrome Scale (PANSS), the Warwick-Edinburgh Mental Wellbeing Scale (SWEMWBS), the Global Assessment of Functioning Scale (GAF), the Brief Negative Symptom Scale (BNSS), and pharmacokinetic parameters were used to analyse the efficacy of the treatment...

BACKGROUND: Hyperprolactinemia is a commonly underestimated adverse effect of antipsychotic medications. There are still no consensus guidelines for the optimal monitoring and treatment strategies. OBJECTIVE: The aim of the study was to assess the monitoring and treatment practices of antipsychotic- induced hyperprolactinemia, in addition to the prevalence and risk factors associated with it. METHODS: A retrospective cohort observational study was conducted among patients attending the psychiatric clinics at an academic tertiary hospital in Riyadh, Saudi Arabia, from May 2020 until May 2021, by reviewing each patient's medical record for up to five years...

Here, authors report on an interesting case of early-onset of schizophrenia where adjunctive pregabalin alleviated risperidone-induced pseudoparkinsonism, helped with insomnia and agitation and boosted antipsychotic response with great tolerability. We wager that gabapentenoids can be a viable option in the niche of psychopharmacotherapy of schizophrenia in CAP population.

Treatment resistance in anxiety disorders represents a clinical challenge, contributes to the chronicity of the diseases as well as sequential comorbidities, and is associated with a significant individual and socioeconomic burden. This narrative review presents the operational definition of treatment resistance in anxiety disorders according to international consensus criteria (< 50% reduction in the Hamilton Anxiety Scale, HAM‑A, score or < 50% reduction in the Beck Anxiety Inventory, BAI, score or a clinical global impression-improvement, CGI‑I, score > 2)...

This report presents a case of particular interest in terms of course and therapeutic outcomes, concerning a patient suffering from treatment-resistant depression in whom adjunctive cariprazine to medication brought about an immediate overall improvement in symptomatology. Informed written consent was obtained from the subject for publication of the case.

Background Major depressive disorder (MDD) has many facets including mixed or atypical depression that requires personalized care to improve treatment-related outcomes. Second-generation antipsychotics (SGAs) offer complementary mechanisms for clinical roles in difficult-to-treat depression and treatment-resistant depression cases. Aim/objective To further delineate a consensus on the clinical positioning of SGAs for MDD, mixed, or atypical depression, a Knowledge Attitude Perception (KAP)-mediated Delphi Statement was planned...

BACKGROUND: Antipsychotics are the gold standard treatment for schizophrenia, but many patients who receive treatment experience persistent symptoms. The aim of this network meta-analysis was to determine the efficacy of augmentation drugs for the treatment of schizophrenia. METHODS: In accordance with the PRISMA statement, the PubMed, Web of Science, Google Scholar, CENTRAL, clinical trial and EUDRACT databases were searched from inception to May 15th, 2023. To ensure the robustness of the results, only double-blind randomised controlled trials with a low risk of bias (measured by the Risk Of Bias v2 (ROB2) tool) were included...

INTRODUCTION: The rate of pharmacoresistance among in patients diagnosed with schizophrenia is around 30%. Clozapineis the drug of choice for these patients; however, an adequate response to treatment doesn't always occur. One of the possible augmentation approaches, specifically for non-adherent patients, is the administration of long-acting parenteral antipsychotics. Our goal was to evaluate previous experiences of administering a combination of the atypical antipsychotic clozapine and long-acting injectable antipsychotics to pharmacoresistant patients at the Department of Psychiatry the Czech Republic and to assess the safety and effectiveness of such administration...

Obsessive-compulsive disorder (OCD) is a chronic disease with a prevalence in the general population of around 2%-3%, generally accompanied by a severe impairment of functioning and quality of life. A consistent subgroup of patients may not achieve adequate symptom remission with first-line treatments (i.e., cognitive behavioral therapy, selective serotonin reuptake inhibitors [SSRIs]). The most validated option for treatment-resistant cases relies on the augmentative use of antipsychotics to SSRIs, preferably of the 'second generation'...

OBJECTIVE: We aimed at exploring the relationship between functional outcomes in patients on clozapine augmented with antipsychotics in treatment-resistant schizophrenia using standard outcome measures Health of Nation Outcome Scales (HoNOS) and Life Skills Profile (LSP-16). METHOD: In a cross-sectional study of 83 patients on clozapine treated in a psychiatric rehabilitation hospital, the association between the primary outcome measure, LSP-16 including its subscales, and treatment with antipsychotic augmentation (AA) were analysed using linear regression...

INTRODUCTION: Depression rates in children/adolescents in the United States have increased in the last 10 years. Fluoxetine and escitalopram are the only 2 antidepressants approved for the treatment of major depression disorder (MDD) in children/adolescents. In adults, some antipsychotics are approved for augmented treatment of MDD. However, there is limited research on antipsychotic augmentation in child/adolescent MDD. METHODS: This retrospective chart review evaluated antipsychotic prescribing for MDD in hospitalized patients aged 4 to 17 years to determine the frequency of prescribing antipsychotics for MDD and what factors influence the addition of an antipsychotic...

BACKGROUND: Clozapine is the primary antipsychotic (APD) for treatment-resistant schizophrenia (TRS). However, only 40% of patients with TRS respond to clozapine, constituting a subgroup of clozapine-resistant patients. Recently, the neuropeptide orexin-A was shown to be involved in the pathophysiology of schizophrenia. This study evaluated the association of orexin-A levels with the clozapine response in patients with TRS. METHODS: We recruited 199 patients with schizophrenia, including 37 APD-free and 162 clozapine-treated patients...

OBJECTIVE: The present network meta-analysis (NMA) was conducted to compare and generate evidence for the most efficacious treatment among available pharmacological interventions for treatment-resistant schizophrenia (TRS). METHODS: Reviewers extracted data from 47 studies screened from PubMed/MEDLINE, Embase, Cochrane databases and clinical trial registries fulfilling the eligibility criteria. Random effects Bayesian NMA was done with non-informative priors. Network geometry was visualized, and node splitting was done for the closed triangles...

BACKGROUND: Depression in patients with schizophrenia worsens the course of the disease by increasing the risk of suicide, by complicating the clinical picture of the disorder, and by reducing the quality of the social functioning; its treatment is difficult, since monotherapy, even when involving modern antipsychotics, does not always prove successful. While the prescription of additional antidepressants (ADs) can improve the likelihood of a better outcome, the effectiveness of such augmentation in many cases is yet to be proven...
