Clinical Global Impressions-Severity Of Illness Research Articles

Defining a clinically meaningful within-patient change threshold for the Cohen-Mansfield Agitation Inventory in Alzheimer's dementia.

The Cohen-Mansfield Agitation Inventory (CMAI) quantifies the frequency of agitation behaviors in elderly persons. This post hoc analysis of data from the brexpiprazole clinical program aimed to determine a meaningful within-patient change (MWPC) threshold for CMAI Total score among patients with agitation associated with dementia due to Alzheimer's disease. Data were included from three 12-week, multicenter, randomized, double-blind, placebo-controlled, parallel-arm trials of brexpiprazole for the treatment of agitation associated with dementia due to Alzheimer's disease (ClinicalTrials.gov identifiers: NCT01862640, NCT01922258, NCT03548584). Change in CMAI Total score (range 29-203; higher scores indicate higher frequency of agitation behaviors) from baseline to Week 12 was the primary endpoint in each trial. MWPC thresholds were estimated from anchor-based mean change analyses and receiver operating characteristic (ROC) curves. The Clinical Global Impression-Severity of illness (CGI-S) and Clinical Global Impression-Improvement (CGI-I) scales, both as related to agitation, were used as anchors. Empirical cumulative distribution functions (eCDFs) and probability density functions (PDFs) were plotted as supportive evidence. Distribution-based methods were also employed. Data from 898 patients were analyzed (mean age, 73.7 years; mean baseline CMAI Total score, 73.8). The mean CMAI Total score change corresponding to a difference of small improvement vs. stable (CGI-S one-point decrease vs. no change), or minimally improved vs. no change (CGI-I rating of 3 vs. 4), ranged from -10.6 to -13.5 points. The mean CMAI Total score change corresponding to a difference of moderate improvement vs. stable (CGI-S two-point decrease vs. no change), or much improved vs. no change (CGI-I rating of 2 vs. 4), ranged from -20.2 to -25.7 points. ROC curve analyses generally produced smaller estimates of meaningful change. eCDFs and PDFs showed good distribution and separation of CMAI Total score change between CGI-S/CGI-I categories. In distribution-based analyses, the minimal detectable change for CMAI Total score (10.5-11.8 points) was generally lower than anchor-suggested thresholds. Triangulation of evidence from anchor- and distribution-based analyses supports an MWPC threshold for CMAI Total score of -20 points, with a threshold range of -15 to -25 points, in patients with agitation associated with dementia due to Alzheimer's disease.

A randomised, open-label, pragmatic pilot comparison of oral and intravenous ketamine in treatment-resistant depression

BackgroundFor depression, ketamine is more conveniently administered by oral than by intravenous (iv) routes. The relative antidepressant efficacy of oral vs iv ketamine is unknown. ObjectivesTo assess the acute efficacy and the persistence of improvement with open-label oral versus iv ketamine in outpatients with treatment-resistant depression (TRD). MethodsAdults with TRD were randomized to oral (N=30) or IV (N=31) ketamine. Oral ketamine was dosed at 150 mg in 50 mL of water, sipped across 15 min. IV ketamine was dosed at 0.5 mg/kg, infused across 40 min. Ketamine sessions (total, 7) were administered on alternate days for 2 weeks. Ongoing antidepressant drugs were continued unchanged. Patients were assessed at baseline, day 14, and day 30. The primary outcome was the endpoint Hamilton Rating Scale for Depression score on day 14. Secondary outcomes were endpoint scores on the Montgomery-Asberg Depression Rating Scale, Beck Depression Inventory, and Clinical Global Impression-Severity of Illness and Improvement. ResultsOverall dropout was lower with oral than with iv ketamine (26.7 % vs 54.8 %; P=0.03). The 2 groups did not differ in depression ratings and in response and remission rates on all instruments on both days 14 and 30. Adverse events such as headache (56.7 % vs 74.2 %) and drowsiness (0.0 % vs 22.6 %) were less common with oral ketamine. ConclusionIn TRD outpatients treated in general hospitals, oral ketamine maybe better accepted and tolerated than iv ketamine. Conclusions about relative efficacy cannot be drawn because of the high dropout rate with iv ketamine.

Efficacy and safety of brexpiprazole for the treatment of agitation in Alzheimer's disease: a meta-analysis of randomized controlled trials.

Recent randomized controlled trials (RCTs) have shown a benefit of brexpiprazole in managing agitation in patients with Alzheimer's disease (AD). However, its efficacy and safety remain unclear. We systematically searched PubMed, Embase, and Cochrane Library for RCTs comparing brexpiprazole with placebo in patients with agitation and AD. Three studies comprising 1,048 patients were included. In patients with agitation and AD, brexpiprazole significantly improved the Cohen-Mansfield Agitation Inventory total score (CMAI) at any dose (MD -3.05; 95% CI -5.12, -0.98; p < 0.01; I2 = 19%) and at 2mg (MD -4.36; 95% CI -7.02, -1.70; p < 0.01; I2 = 0%) over 12weeks. Brexpiprazole at any dose and 2mg also showed benefit in the Clinical Global Impression - Severity of illness (CGI-S) score as related to agitation over 12weeks (MD -0.20; 95% CI -0.36, -0.05; p < 0.01; I2 = 35%). There is no significant difference between the groups in the incidence of at least one treatment-emergent adverse events (TEAEs; RR 1.14; 95% CI 0.95, 1.37; p = 0.16; I2 = 45%) and all-cause mortality (RR 1.99; 95% CI 0.37, 10.84; p = 0.42; I2 = 0%). Brexpiprazole at any dose significantly increased the Simpson-Angus Scale (SAS; MD 0.47; 95% CI 0.28, 0.66; p < 0.01). Our results suggest that brexpiprazole is more efficacious than placebo in the treatment of agitation in AD patients. Further studies are still necessary to confirm long-term effects of brexpiprazole.Prospero registry: CRD42023486694.

The effects of treatment with pimavanserin on activities of daily living in patients with Parkinson's disease psychosis: a 16-week, single-arm, open-label study.

More than half of patients with Parkinson's disease will experience psychosis symptoms in the form of hallucinations or delusions at some point over the course of their disease. These symptoms can significantly impact patients' health-related quality of life, cognitive abilities, and activities of daily living (ADLs) and function. Clinical assessment of how psychosis impacts these measures is crucial; however, few studies have assessed this sufficiently, in part due to a lack of appropriate scales for comprehensively assessing function. The objective was to assess how symptoms of Parkinson's disease psychosis (PDP) impact ADLs and function, cognitive function, and health-related quality of life. To address this unmet need, we utilized a modified version of the Functional Status Questionnaire (mFSQ) to measure the impact of psychosis on ADLs and function in patients with PDP treated with pimavanserin, a US Food and Drug Administration-approved medication to treat hallucinations and delusions associated with PDP. Eligible patients entered a 16-week, single-arm, open-label study of oral pimavanserin (34 mg) taken once daily. The primary endpoint was change from baseline to Week 16 on the mFSQ. Secondary endpoints included the Movement Disorders Society-modified Unified Parkinson's Disease Rating Scale (MDS-UPDRS) I and II; Schwab and England ADL; Clinical Global Impression-Severity of Illness (CGI-S), Clinical Global Impression-Improvement (CGI-I), and Patient Global Impression-Improvement (PGI-I), and were also measured as change from baseline to Week 16 using mixed-effects model for repeated measures (MMRM) and least-squares mean (LSM). Our results in a proof-of-concept, 16-week, open-label clinical study in 29 patients demonstrated that an improvement in psychosis symptoms following treatment with pimavanserin was associated with improvements in multiple measures of ADLs and function. Notably, a significant improvement was found on the primary endpoint, change from baseline to Week 16 in mFSQ score [LSM [SE] 14.0 [2.50], n = 17; 95% CI (8.8, 19.3); p < 0.0001]. These findings highlight the potential for improvement in function with improvement of psychosis symptoms in patients with PDP and suggest that the mFSQ may be a measurement tool to evaluate the level of improvement in function.

Psychopathology and Pattern of Remission of Cannabis-Induced Psychotic Disorder.

Objective: To analyze the psychopathology and pattern of remission in cannabis-induced psychotic disorder with treatment.Methods: This was a prospective cohort study of a group of patients admitted with new-onset psychosis, cannabis use, and no evidence of other drug abuse from January 1 to June 31, 2019, to the psychiatry inpatient department of a multispecialty tertiary care hospital in Kerala, India. Patients were evaluated at admission and after 1 week in the hospital and 1 month after discharge using the Structured Clinical Interview for the Positive and Negative Syndrome Scale and the Clinical Global Impressions-Severity of illness scale.Results: Fifty-six male subjects were recruited for the study. The mean age of the subjects was 22.2 years, and the majority were active smokers of nicotine and cannabis. Total duration of abuse and family history of substance use in first-degree relatives correlated with severity of psychosis. Hostility, excitement, and grandiosity were the predominant positive symptoms, and these symptoms showed a steady reduction toward the end of the study. The most frequent negative symptoms were emotional withdrawal, passive or apathetic social withdrawal, and difficulty in abstract thinking, and these symptoms also showed significant improvement (P < .001 for all). For symptoms such as somatic concern and guilt feelings, significant treatment response was noted only in the initial week (P < .001).Conclusions: Cannabis-induced psychosis in the Indian setting presents with predominant positive symptoms and minimal affective symptoms. The steady improvement noted with complete cessation of cannabis indicates a possible contributory role for cannabis in precipitating psychosis.

Effects of Long-acting Injectable 3-Monthly Paliperidone Palmitate on the Clinical and Social Performance of Patients with Schizophrenia

To investigate the effects of long-acting injectable 3-monthly paliperidone palmitate on the clinical and social functioning of patients with schizophrenia. This study enrolled patients with schizophrenia receiving long-acting injectable 1-monthly paliperidone palmitate for at least 4 months and who subsequently received 3-monthly paliperidone palmitate. Accordingly, 418 patients were followed up for 24 weeks. Their clinical symptoms and social functioning were measured using the Clinical Global Impression-Severity of Illness and Personal and Social Performance scales. The Personal and Social Performance total score was significantly higher after 3-monthly paliperidone palmitate treatment than at baseline (baseline vs. week 24: 54.3 ± 18.0 vs. 61.0 ± 14.5 [mean ± standard deviation]; p < 0.001; Wilcoxon signed-rank test); the proportion of patients in the mildly ill group (scores 71-100) also increased significantly (baseline vs. week 24: 16.5% vs. 20.6%; p < 0.001; McNemar-Bowker test). The mean Clinical Global Impression-Severity of Illness score decreased significantly (baseline vs. week 24: 3.7 ± 1.0 vs. 3.4 ± 0.9; p < 0.001; Wilcoxon signed-rank test), as did the proportion of patients in the severely ill group (baseline vs. week 24: 4.1% vs. 2.1%; p < 0.001; McNemar-Bowker test). Continuous 3-monthly paliperidone palmitate treatment significantly enhances the personal and social performance of patients with schizophrenia and reduces the proportion of those with severe illness. These findings suggest that long-acting injectable antipsychotic administration at intervals longer than 1 month might improve the social functioning of and promote return to activities of daily living in patients with schizophrenia.

Efficacy, Safety and Tolerability of Brexpiprazole for the Treatment of Agitation in Alzheimer’s Dementia: A 12‐Week, Randomized, Double‐Blind, Placebo‐Controlled Trial

AbstractBackgroundAgitation is a prevalent clinical manifestation of Alzheimer’s dementia, and is one of the most stressful aspects of care in patients affected by the disease. However, currently, there are no FDA‐approved pharmacological treatments for agitation in this patient population. Following two prior clinical trials of brexpiprazole in this patient population, the aim of this study was to confirm the efficacy, safety and tolerability of brexpiprazole in patients with agitation in Alzheimer’s dementia.MethodsThis was a 12‐week, multicenter, randomized, double‐blind, placebo‐controlled, parallel‐arm study (NCT03548584). Eligible patients were aged 55–90 years, in a care facility or community‐based setting, had a diagnosis of probable Alzheimer’s disease, and met criteria for agitation as defined by the International Psychogeriatric Association (IPA). Patients were randomized 2:1 to brexpiprazole or placebo; within the brexpiprazole arm, patients were further randomized 1:2 to fixed‐dose 2 mg/day or 3 mg/day. Stable background medications for the treatment of Alzheimer’s disease were permitted. The primary endpoint was change from baseline to Week 12 in Cohen–Mansfield Agitation Inventory (CMAI) Total score. The key secondary endpoint was change from baseline to Week 12 in Clinical Global Impression − Severity of illness (CGI‐S) score, as related to agitation. Safety was also assessed.ResultsA total of 345 patients were randomized to brexpiprazole or placebo. On the primary endpoint, the mean change from baseline to Week 12 in CMAI Total score was statistically significantly greater in the brexpiprazole group (2 mg/day or 3 mg/day) versus the placebo group (p = 0.0026). Statistically significant separation between the brexpiprazole and placebo groups was also observed on the key secondary endpoint of change from baseline to Week 12 in CGI‐S score (p = 0.0055). Aside from headache (6.6%), no other treatment‐emergent adverse events occurred with an incidence ≥5% in the brexpiprazole group.ConclusionIn this Phase 3 study of patients with agitation in Alzheimer’s dementia, treatment with brexpiprazole was associated with a statistically significantly greater reduction in agitation, and improvement in clinical global impression of agitation, compared with placebo, supporting the findings of two prior clinical trials. Brexpiprazole was generally well tolerated, and no new safety signals were observed.

Interpersonal therapy versus antidepressant medication for treatment of postpartum depression and anxiety among women with HIV in Zambia: a randomized feasibility trial.

IntroductionPostpartum depression (PPD) is a prevalent and debilitating disease that may affect medication adherence and thus maternal health and vertical transmission among women with HIV. We assessed the feasibility of a trial of interpersonal psychotherapy (IPT) versus antidepressant medication (ADM) to treat PPD and/or anxiety among postpartum women with HIV in Lusaka, Zambia.MethodsBetween 29 October 2019 and 8 September 2020, we pre‐screened women 6–8 weeks after delivery with the Edinburgh Postnatal Depression Scale (EPDS) and diagnosed PPD or anxiety with the Mini International Neuropsychiatric Interview. Consenting participants were randomized 1:1 to up to 11 sessions of IPT or daily self‐administered sertraline and followed for 24 weeks. We assessed EPDS score, Clinical Global Impression‐Severity of Illness (CGI‐S) and medication side effects at each visit and measured maternal HIV viral load at baseline and final study visit. Retention, visit adherence, change in EPDS, CGI‐S and log viral load were compared between groups with t‐tests and Wilcoxon signed rank tests; we report mean differences, relative risks and 95% confidence intervals. A participant satisfaction survey assessed trial acceptability.Results78/80 (98%) participants were retained at the final study visit. In the context of the COVID‐19 pandemic, visit adherence was greater among women allocated to ADM (9.9 visits, SD 2.2) versus IPT (8.9 visits, SD 2.4; p = 0.06). EPDS scores decreased from baseline to final visit overall, though mean change was greater in the IPT group (−13.8 points, SD 4.7) compared to the ADM group (−11.4 points, SD 5.5; p = 0.04). Both groups showed similar changes in mean log viral load from baseline to final study visit (mean difference −0.43, 95% CI −0.32, 1.18; p = 0.48). In the IPT group, viral load decreased significantly from baseline (0.9 log copies/ml, SD 1.7) to final visit (0.2 log copies/ml, SD 0.9; p = 0.01).ConclusionsThis pilot study demonstrates that a trial of two forms of PPD treatment is feasible and acceptable among women with HIV in Zambia. IPT and ADM both improved measures of depression severity; however, a full‐scale trial is required to determine whether treatment of PPD and anxiety improves maternal–infant HIV outcomes.

Decrease in Social Zeitgebers Is Associated With Worsened Delayed Sleep-Wake Phase Disorder: Findings During the Pandemic in Japan.

BackgroundDelay in sleep-wake rhythms was observed in the general population during the coronavirus disease 2019 (COVID-19) pandemic. Patients with delayed sleep-wake phase disorder (DSWPD) may have also experienced exacerbation of symptoms, but no studies have investigated this topic. In this study, we aimed to retrospectively examine the changes in symptoms of outpatients with DSWPD both before and during the pandemic and to identify the factors associated with the exacerbation of sleep-wake rhythms.MethodsWe included outpatients with DSWPD aged 16 years or older who visited the outpatient clinic due to sleep disorders between January and September 2020. Decreased social zeitgebers was defined as a reduction of 50% or more in the frequency of commuting to school or work during the COVID-19 pandemic. The severity of DSWPD was assessed using the clinical global impressions - severity of illness (CGI-S) at two points: before and during the pandemic. We defined the worsened, unchanged, and improved groups as those whose CGI-S scores worsened by at least one point, remained unchanged, and improved by at least one point, respectively. Multivariate logistic regression analysis was performed to determine the factors associated with worsened DSWPD symptoms.ResultsSixty patients with DSWPD were eligible for this study. Even before the pandemic, patients who were unemployed or did not attend school tended to show more severe DSWPD symptoms. During the pandemic, 27 patients belonged to the worsened group; 28 patients, unchanged group; and 5 patients, improved group. Decreased social zeitgebers (odds ratio [OR] = 6.668, 95% confidence interval [CI]: 1.653–26.891, p < 0.05) and comorbid mood disorders (OR = 8.876, 95% CI: 1.714–45.974, p < 0.05) showed independent significant associations with the worsening of DSWPD symptoms.ConclusionsDuring the pandemic, the symptoms of DSWPD tended to worsen. The obtained findings emphasize the importance of social zeitgebers, suggesting the need for external motivation in DSWPD treatment.

Transcutaneous electrical acupoint stimulation for children with attention-deficit/hyperactivity disorder: a randomized clinical trial

Little is known about the effects of transcutaneous electrical acupoint stimulation (TEAS) for children with attention-deficit/hyperactivity disorder (ADHD). Here, we carried out a 4 week randomized clinical trial in which patients aged 6–12 years old with an ADHD diagnosis received TEAS or sham TEAS. The primary outcome measure was the investigator-rated Clinical Global Impression-Improvement (CGI-I) score at week 4. Secondary outcomes included changes from baseline to week 4 in the investigator-rated Clinical Global Impression-Severity of Illness (CGI-S) score, the Conners’ Parent/Teacher Rating Scales-Revised: Short Form (CPRS-R: S/CTRS-R: S) score, go/no-go task performance, and functional near-infrared spectroscopy (fNIRS)-based oxygenated hemoglobin level within the prefrontal cortex. At week 4, the CGI-I score indicated improvement in 33.3% of the TEAS group compared with 7.7% of the sham group (P = 0.005). The TEAS group had a greater decrease in the mean CGI-S score (−0.87) than the sham TEAS group (−0.28) (P = 0.003). A greater enhancement in the mean cerebral oxygenated hemoglobin within the prefrontal cortex was found in the TEAS group (0.099 mM mm) compared with the sham TEAS group (0.005 mM mm) (P < 0.001). CPRS-R: S score, CTRS-R: S score, and go/no-go performance exhibited no significant improvement after TEAS treatment. The manipulation-associated adverse events were uncommon in both groups, and events were very mild. Our results show that noninvasive TEAS significantly improved general symptoms and increased prefrontal cortex blood flow within 4 weeks for children with ADHD. Further clinical trials are required to understand the long-term efficacy in a larger clinical sample. This trial was registered on ClinicalTrials.gov (NCT 03917953).

Distinct Effects of Antidepressants in Association With Mood Stabilizers and/or Antipsychotics in Unipolar and Bipolar Depression.

There is a dearth of studies comparing the clinical outcomes of patients with treatment-resistant unipolar (TRD) depression and depression in bipolar disorder (BD) despite similar treatment strategies. We aimed to evaluate the effects of the pharmacological combinations (antidepressants [AD], mood stabilizers [MS], and/or antipsychotics [AP]) used for TRD and BD at the McGill University Health Center. We reviewed health records of 206 patients (76 TRD 130 BD) with TRD and BD treated with similar augmentation strategies including AD with MS (AD+MS) or AP (AD+AP) or combination (AD+AP+MS). Clinical outcomes were determined by comparing changes on the 17-time Hamilton Depression Rating Scale (HAMD-17), Quick Inventory of Depressive Symptomatology, and Clinical Global Impression-Severity of Illness at the beginning (T0) and after 3 months of an unchanged treatment (T3). Baseline HAMD-17 scores in TRD were higher than in BD (P < 0.001), but TRD patients had a greater improvement at end point (P = 0.003). Antidepressants with AP generated greater reductions in HAMD-17 in TRD compared with BD (P = 0.02). Importantly, in BD patients, the addition of AD compared with other treatment strategies failed to improve the outcome. The limitations of this study include possibly unrepresentative subjects from tertiary care settings, incomplete matching of BD and TRD subjects, nonrandomized treatment with unmatched agents, doses, and times, unknown treatment adherence, and nonblinded retrospective outcome assessments. Nevertheless, the findings may reflect real-world interactions of clinically selected pharmacotherapies. Combination of augmentation strategies such as AD+AP and/or MS showed a better clinical improvement in patients with TRD compared with BD suggesting a limited evidence for AD potentiation in BD.

Comparison of pramipexole versus ropinirole in the treatment of Parkinson's disease.

Parkinson's disease is a progressive neurodegenerative disease characterized by motor and non-motor symptoms. Levodopa is the most effective drug in the symptomatic treatment of the disease. Dopamine receptor agonists provide sustained dopamin-ergic stimulation and have been found to delay the initiation of levodopa treatment and reduce the frequency of various motor complications due to the long-term use of levodopa. The primary aim of this study was to compare the efficacy of potent nonergoline dopamine agonists pramipexole and ropinirole in both "dopamine agonist monotherapy group" and "levodopa add-on therapy group" in Parkinson's disease. The secondary aims were to evaluate the effects of these agents on depression and the safety of pramipexole and ropinirole. A total of 44 patients aged between 36 and 80 years who were presented to the neurology clinic at Ministry of Health Diskapi Yildirim Beyazit Training and Research Hospital, Ankara, Turkey and were diagnosed with idiopathic Parkinson's disease, were included into this randomized parallel-group clinical study. Dopamine agonist monotherapy and levodopa add-on therapy patients were randomized into two groups to receive either pramipexole or ropinirole. The maximum daily dosages of pramipexole and ropinirole were 4.5 mg and 24 mg respectively. Patients were followed for 6 months and changes on Unified Parkinson's Disease Rating Scale, Clinical Global Impression-severity of illness, Clinical Global Impression-improvement, Beck Depression Inven-tory scores, and additionally in advanced stages, changes in levodopa dosages were evaluated. Drug associated side effects were noted and compared. In dopamine agonist monotherapy group all of the subsections and total scores of Unified Parkinson's Disease Rating Scale and Clinical Global Impression-severity of illness of the pramipexole subgroup showed significant improvement particularly at the end of the sixth month. In the pramipexole subgroup of levodopa add-on therapy group, there were significant improvements on Clinical Global Impression-severity of illness and Beck Depression Inventory scores, but we found significant improvement on Clinical Global Impression-severity of illness score at the end of the sixth month in ropinirole subgroup too. The efficacy of pramipexole and ropinirole as antiparkinsonian drugs for monotherapy and levodopa add-on therapy in Parkinson's disease and their effects on motor complications when used with levodopa treatment for add-on therapy have been demonstrated in several previous studies. This study supports the effectiveness and safety of pramipexole and ropinirole in the monotherapy and levodopa add-on therapy in the treatment of Parkinson's disease.

Systematic Review on Parkinson's Disease Medications, Emphasizing on Three Recently Approved Drugs to Control Parkinson's Symptoms.

Parkinson’s Disease (PD) is a disease that involves neurodegeneration and is characterised by the motor symptoms which include muscle rigidity, tremor, and bradykinesia. Other non-motor symptoms include pain, depression, anxiety, and psychosis. This disease affects up to ten million people worldwide. The pathophysiology behind PD is due to the neurodegeneration of the nigrostriatal pathway. There are many conventional drugs used in the treatment of PD. However, there are limitations associated with conventional drugs. For instance, levodopa is associated with the on-off phenomenon, and it may induce wearing off as time progresses. Therefore, this review aimed to analyze the newly approved drugs by the United States-Food and Drug Administration (US-FDA) from 2016–2019 as the adjuvant therapy for the treatment of PD symptoms in terms of efficacy and safety. The new drugs include safinamide, istradefylline and pimavanserin. From this review, safinamide is considered to be more efficacious and safer as the adjunct therapy to levodopa as compared to istradefylline in controlling the motor symptoms. In Study 016, both safinamide 50 mg (p = 0.0138) and 100 mg (p = 0.0006) have improved the Unified Parkinson’s Disease Rating Scale (UPDRS) part III score as compared to placebo. Improvement in Clinical Global Impression—Change (CGI-C), Clinical Global Impression—Severity of Illness (CGI-S) and off time were also seen in both groups of patients following the morning levodopa dose. Pimavanserin also showed favorable effects in ameliorating the symptoms of Parkinson’s Disease Psychosis (PDP). A combination of conventional therapy and non-pharmacological treatment is warranted to enhance the well-being of PD patients.

Antipsychotic nonadherence measured by electronic adherence monitoring in stabilized chronic schizophrenia: Clinical implications

BackgroundThere have been a number of studies investigating antipsychotic adherence measured by electronic adherence monitoring (EAM) in patients with schizophrenia. However, no study has looked at overall adherence and both baseline and endpoint illness/symptom severity. MethodsWe performed a secondary analysis of our previous study to examine antipsychotic adherence, as measured by EAM, and illness/symptom severity at baseline and endpoint in patients with schizophrenia. Adherence rates were defined as the proportion of adherent days over 3 months. Adherent days were defined as the subject having taken the medication at the prescribed time, with 2 tolerance margins operationally defined i.e., ±3 h and ±12 h. In addition, a dichotomous version of adherence was defined i.e., if he/she was adherent greater than 80% of the days. Illness severity and symptom severity were assessed using the Brief Psychiatric Rating Scale (BPRS) total score and the Clinical Global Impression – Severity of illness (CGI-S) scale score, respectively. ResultsA total of 111 patients were enrolled in the study. Neither continuous or dichotomous adherence rates were significantly associated with baseline or endpoint illness/symptom severity (all Ps ≥ 0.05). The results remained unchanged when adjusting for clinico-demographic characteristics. ConclusionAntipsychotic adherence, as measured by EAM, was not associated with illness/symptom severity at baseline and endpoint in patients with chronic schizophrenia, whose clinical status and adherence pattern were stabilized. This suggests that individuals may be able to achieve clinical stability in the face of maintenance antipsychotic treatment despite variations in adherence.

Depression treatment in women and men with bipolar affective disorder: a comparative study

Objective: to compare depression treatment efficacy with and without antidepressants (ADs) in men and women with bipolar affective disorder (BAD).Patients and methods. We enrolled 100 patients with BAD (F31.3–F31.5 according to ICD-10), including 50 women aged 33.0 [23.0; 50.2] years and 50 men aged 37.5 [29.5; 47.2] years using prospective and retrospective methods. Various antidepressants, normothymics, antipsychotics combinations were used to treat depression. We performed a comparative analysis of treatment efficacy with and without antidepressants in men and women subgroups. Clinical assessment at the baseline and the end of 1, 2, 4, 6-th week of therapy (or at discharge) included a specially developed clinical examination chart and the following psychometric scales: Montgomery-Asberg Depression Rating Scale (MADRS), Clinical Global Impression – Severity of illness (CGI-S), Clinical Global Impression – Improvement (CGI-I).Results and discussion. Women tended to have a slower improvement in the condition compared to men. Maximum reduction in MADRS score and a CGI-I, CGI-S higher frequency of clinical improvement and remission was observed in men and women who did not receive antidepressants than patients who did not receive antidepressants. When BAD type was included in the analysis, in patients treated with antidepressants, transient symptoms of the opposite pole occurred in 24.7% of patients of both sexes with bipolar affective I disorder (BAD I) and in 16.8% with bipolar affective II disorder (BAD II). There were no significant gender differences in patients with BAD I, while women predominated in BAD II group (22.5% compared to 7.8% men). No significant treatment-emergent affective switch was observed with tricyclic antidepressants and selective serotonin and norepinephrine reuptake inhibitors in both groups (21; 16.7; 16.7% in men and 28; 21.8; 12.5% in women, respectively). The assessment of intermission revealed that women were significantly more likely to have shorter periods between phases (42% compared to 22% in men). In addition, women were significantly more likely to have shorter periods between phases (42% compared to 22% in men) when the intermission duration was included in the analysis. In some patients with severe depression and infective first-line therapy (anticonvulsants and atypical antipsychotics), antidepressants prescription can increase treatment effectiveness. However, several factors should be considered, such as BAD type and variant, depression severity, treatment-emergent affective switch in history, and gender.Conclusion. A decision about antidepressants' dosage and treatment duration requires a dynamic follow-up of the patient in order to discontinue the antidepressants as fast as possible and decrease the risk of treatment-emergent affective switch and shortening of remission period.

Continuation rate for asenapine and brexpiprazole treatment in patients with schizophrenia.

IntroductionThe current study sought to compare the treatment continuation rates of asenapine and brexpiprazole while specifically investigating the factors influencing this index and the clinical efficacy of brexpiprazole.MethodsRetrospective study on patients with schizophrenia who were prescribed either asenapine (n = 73) or brexpiprazole (n = 136), as part of their routine medical care.ResultsThe treatment continuation rates for asenapine and brexpiprazole were 19.0% and 38.6% at 52 weeks, with that of brexpiprazole found to be significantly higher than that of asenapine (p = .002). Moreover, age was found to be a significant factor affecting the treatment continuation rate for brexpiprazole (p = .03). Additionally, patients with a longer continuation duration had significantly lower Clinical Global Impression‐Severity of Illness (CGI‐S) scale scores compared to those who discontinued early (p = .04). The continuation rate was also significantly higher for those who began using the drug as outpatients compared to those first administered the drug as inpatients (p = .04). Furthermore, disease duration, CGI‐S scale, and continuation duration significantly affected the clinical efficacy of brexipiprazole (p < .05 for all).ConclusionsThe continuation rate for brexpiprazole increases as the age of the patient increases, as disease severity decreases, and if the patient first uses the drug as an outpatient. Shorter disease duration and longer drug administration may lead to improved clinical efficacy. These results suggest that brexpiprazole is an effective treatment option for maintenance therapy of schizophrenia.

Effects of celecoxib augmentation of antidepressant or anxiolytic treatment on affective symptoms and inflammatory markers in patients with anxiety disorders: exploratory study

Prolonged stress has been associated with elevated levels of circulating proinflammatory cytokines. Cyclo-oxygenase-2 inhibitors such as celecoxib exert anti-inflammatory effects and may enhance the response to antidepressant drug treatment in patients with depressive disorders, but their effect on anxiety symptoms in patients with anxiety disorders is uncertain. Patients with a primary diagnosis of an anxiety disorder, with stabilised symptoms, underwent either 6 weeks of celecoxib augmentation of continued treatment (n = 18) or continued 'treatment as usual' (n = 9). Assessments included the Warwick-Edinburgh mental well-being Scale (WEMWEBS), Hospital Anxiety and Depression Scale (HADS), Oxford questionnaire of emotional side effects of antidepressants (OQUESA) and Clinical Global Impression of Illness Severity (CGI-S). Venous blood samples were collected for assays of inflammatory cytokines. Patients who underwent celecoxib augmentation showed significant reductions in anxiety (HADS-A -3.17) and depressive (HADS-D -2.11) symptoms and in overall illness severity (CGI-S -1.11), and improvements in mental well-being (WEMWBS 7.5) and positive changes in emotional responsiveness (OQUESA-RP -3.56; OQUESA-AC -4.22): these were not seen with 'treatment as usual'. There were no significant changes in blood levels of inflammatory cytokines in either group. Celecoxib augmentation appeared associated with beneficial effects on anxiety and depressive symptoms and mental well-being. The findings from this pilot study merit further exploration within a double-blind, randomised placebo-controlled study.

Severity of illness and distress in caregivers of patients with schizophrenia: Do internalized stigma and caregiving burden mediate the relationship?

To test a multiple mediation model of internalized stigma and caregiving burden in the relationship between severity of illness and distress among family caregivers of persons living with schizophrenia. This is a cross-sectional study. Data were collected from a consecutive sample of 344 Chinese family caregivers of persons living with schizophrenia between April-August 2018. Instruments used in this research included the Clinical Global Impression-Severity of Illness, the Internalized Stigma of Mental Illness Scale, the Caregiver Burden Inventory, and the Distress Thermometer. Data analysis was conducted using descriptive statistics, the Spearman correlation, and regression analysis to estimate direct and indirect effects using bootstrap analysis. This research found that internalized stigma and caregiving burden can separately and sequentially mediate the relationship between severity of illness and distress. Moreover the mediation of internalized stigma plays the largest role among the multiple mediations. The severity of illness, internalized stigma, and caregiving burden are significant factors of distress among family caregivers of persons living with schizophrenia. The future intervention studies which be designed aiming at the three factors may be beneficial for family caregivers of persons living with schizophrenia. This research examined the psychosocial development of distress and indicated that interventions improving patients' symptoms and decreasing internalized stigma and caregiving burden can help to prevent or reduce distress among family caregivers.

Agomelatine in Standard Medical Practice in Depressed Patients: Results of a 1-Year Multicentre Observational Study In France.

Background and ObjectivesNon-interventional studies are a valuable source of evidence that is complementary to traditional randomised, blinded and controlled clinical trials, for evaluating antidepressants in a real-world setting. The aim of the present study was to document the use of agomelatine in current medical practice and evaluate its effectiveness and safety in outpatients prescribed agomelatine to treat their current depressive episode.MethodsThis 12-month observational French study included patients initiating agomelatine treatment. The intensity and severity of depression were assessed using the 17-item Hamilton Depression Rating Scale (HAM-D17) total score and the Clinical Global Impression-Severity of Illness (CGI-S) scale. Patients’ quality of life and functioning were measured using the Quality of Life in Depression Scale and the Sheehan Disability Scale, respectively. The safety measures included emergent adverse events and biological samplings, with a focus on liver acceptability.ResultsA total of 1484 patients (70% of women; 49.6 ± 15.4 years of age) were enrolled in the study. Most patients (62.3%) were treated with agomelatine for at least 6 months and 28.8% were treated for at least 1 year. Mean HAM-D17 total score and mean CGI-S scores decreased by 13.6 ± 8.1 and 2.1 ± 1.5 points, respectively, from baseline to last visit on agomelatine. Rates of responders (i.e. with a decrease in HAM-D17 total score by at least 50%) and remitters (HAM-D total score < 7) at the last visit were 90.7% and 56.0%, respectively. The mean HAM-D total score decreased after agomelatine withdrawal (− 4.1 ± 6.7) until the last visit. The quality of life and daily functioning of patients improved, while the numbers of days lost and underproductive days decreased over the follow-up period. Safety findings were in accordance with the known information regarding agomelatine.ConclusionIn the current medical practice, this study confirms the effectiveness and good tolerability of agomelatine administered for a treatment period in agreement with guideline recommendations.Trial registration numberISRCTN53570733 on 27 August 2010.

Medication adherence and its correlates among patients affected by schizophrenia with an episodic course: A large-scale multi-center cross-sectional study in China.

The Medication Adherence Rating Scale (MARS) is a fast, non-intrusive way of measuring adherence to medication in order to improve the management of patients with schizophrenia. The current cross-sectional study evaluated the reliability of the Chinese (Mandarin) version of the MARS and explored clinical and demographic correlates to medication adherence in a large sample of patients affected by schizophrenia with an episodic course in China. 1198 patients were recruited from 37 different hospitals in 17 provinces/municipalities of China and evaluated with the Medication Adherence Rating Scale (MARS), Clinical Global Impression-Severity of Illness (CGI-SI) and Sheehan Disability Scale-Chinese version (SDS-C). The MARS showed good internal consistency; Cronbach's alpha of total MARS was 0.83. Among the cohort of patients affected by schizophrenia with an episodic course, 28.5 % met the criteria of good adherence to antipsychotic medication; age, steady income, and severity of illness had significant effects on medication adherence. Medication adherence of patients affected by schizophrenia in mainland China was found to be relatively low, calling for urgent attention and intervention. Risk factors for non-adherence to medication among patients affected by schizophrenia with an episodic course include older age, unsteady income, being in the acute period of the disease, and severity of illness.
