RESUMEN

Background: Partial dopamine D2 receptor agonists are used for psychotic symptoms in adults with schizophrenia spectrum disorders. Recently, interest surged for partial dopamine D2 receptor agonists in substance use disorders (SUDs). Since it is believed that SUDs decrease the efficacy of pharmacotherapy of underlying psychiatric disorders, we tested the efficacy of the partial D2 agonist brexpiprazole in patients with schizophrenia who were either comorbid with a SUD (SUD group) or not comorbid (non-SUD) to assess treatment response and the effect of brexpiprazole on substance craving in SUD. Methods: We included patients with DSM-5/DSM-5-TR schizophrenia (using SCID-5-CV) aged 18-66 years with either comorbid SUD or non-SUD to treat with brexpiprazole 4 mg/day for 6 months during February-October 2022. Patients were assessed with the Clinical Global Impressions-Severity (CGI-S) scale, the 24-item Brief Psychiatric Rating Scale (BPRS), and the Positive And Negative Syndrome Scale (PANSS) at baseline, weekly for the first 2 months and monthly for the next four. Furthermore, we assessed substance craving in SUD with a visual analog scale for craving (VAScrav) at the same timepoints. Results: The total sample was 86 (85 analysable) 18- to 64-year-old (mean 39.32 ± 14.09) patients with schizophrenia [51 men (59.3%) and 35 women (40.7%)], of whom 48 SUD (55.8%) (37 men and 11 women) and 38 non-SUD (44.2%) (14 men and 24 women). No serious or persistent adverse events developed over the study period, but one patient dropped out for subjective akathisia. Results indicated the main effects of time with improvements over the course of the study for CGI-S, BPRS, and PANSS in both SUD and non-SUD groups and the entire sample, and for VAScrav in SUD. Brexpiprazole was associated with similar significant improvements in both groups at the 6 month endpoint compared to baseline. Conclusion: Treatment with brexpiprazole for 6 months improved psychotic symptoms in patients with schizophrenia, independently from whether they belonged to the SUD or the non-SUD group; hence, SUD comorbidity did not confer treatment resistance to brexpiprazole. Furthermore, in the SUD group, we observed reduced substance craving.

RESUMEN

BACKGROUND: Adverse childhood experiences (ACEs), social-emotional impairments (SEIs), and neurodevelopmental disorders (NDs) are frequent in psychiatric disorders, including substance-use disorders. We aimed to determine the prevalence of ACE, SEI, or ND in individuals with cannabis-use disorder (CUD). We compared individuals with preCUD-onset ACE, SEI, or ND to those without. METHODS: We crosssectionally studied 323 inpatients or outpatients with a history of past or current CUD, aged 12-35 years (mean age 22.94 ± 4.79), 64.5% of whom were male. The sample was divided into two groups: the non-premorbid (N = 52) and the premorbid ACE/SEI/ND group (N = 271). Within the premorbid group, further subgroups were based on ACEs, SEI, and NDs. We also analyzed other substance use and psychiatric symptoms/diagnoses based on the non-premorbid-premorbid dichotomy in the CUD sample. RESULTS: Pre-CUD ACE-SEI-ND had higher prevalence of bipolar, schizoaffective, borderline personality, and attention-deficit/hyperactivity disorders, and a history of agitation, hallucinations, and self-injury. The ACE group had higher rates of agitation, depression, delusions, hallucinations, eating disorders, and use of cocaine, amphetamines, and hallucinogens than the SEI or ND. Patients in the premorbid group initiated cannabis use at an earlier age, experienced the first comorbid psychiatric episode earlier, and were hospitalized earlier than those in the non- premorbid ACE-SEI-ND group. CONCLUSIONS: PreCUD-onset ACE, SEI, or ND conditions in individuals with CUDare linked to earlier onset of comorbid mental illness. Furthermore, ACEs contribute to significant and potentially severe clinical symptoms, as well as the use of substances other than cannabis.

RESUMEN

BACKGROUND: The Covid 19 pandemic might have impacted response to drug treatment in major depressive episode (MDE). We compared responses to three different antidepressant drugs, i.e., vortioxetine, sertraline, and trazodone, in outpatients with MDE during Major Depressive Disorder (MDD), Bipolar Disorder (BD), or schizophrenia and related psychoses (SSOPDs) during two time periods, i.e., before and after suffering Covid-19-related trauma. METHODS: We conducted an observational study on clinically stabilised for at least 6 months outpatients with MDE during the course of MDD (N=58), BD (N=33), or SSOPDs (N=51). Patients, whose baseline assessments of Montgomery-Åsberg Rating Scale (MADRS), Hamilton Anxiety Rating Scale (Ham-A), Brief Psychiatric Rating Scale (BPRS), Visual Analogue Scale for Craving (VAS-crav) and World Health Organization Quality of Life, Brief version (WHOQOL-BREF) were available, were recruited at the time they suffered Covid-19-related traumas. Fifty patients, prior to the pandemic, when they were clinically stable, were treated with 15 mg/die vortioxetine, 44 with 450 mg/die trazodone, and 48 with 150 mg/die sertraline. After experiencing a major Covid-19-related personal trauma, patients showed clinical worsening which required dosage adjustment (20 mg/day vortioxetine; 600 mg/day trazodone, and 200 mg/day sertraline) and, for some of them, hospitalisation. Scores on the MADRS, Ham-A, BPRS, VAS-crav and WHOQOL-BREF were compared drug-wise and genderwise with Student's t test for continuous variables and Χ2 for categorical variables. RESULTS: The sample consisted of 142 outpatients (age, mean 39.63 ± 16.84; 70 men and 72 women); women were older than men (mean age 43.18 ± 17.61 vs. 35.98 ± 15.30; p=0.01). The two genders did not differ on other variables. For all treatments, worsening symptoms were observed at the time of trauma, followed by slow recovery with treatment readjustment. Trauma-related worsening in patients on vortioxetine was less intense than patients on the other two antidepressants and recovery was faster. All drugs were associated with an improvement in QoL. The vortioxetine group showed a lower hospitalisation rate (24%) than sertraline (35.4%) and trazodone (38.6%), but this was not significant (p=0.27). CONCLUSION: All drugs improved symptoms of Covid-19 trauma in patients with MDE, with vortioxetine showing a small advantage. No differences between vortioxetine, sertraline and trazodone were found as concerning the need for hospitalisation.

RESUMEN

BACKGROUND: Treatment-resistance in schizophrenia is 30-40%. Its neurobiology remains unclear; to explore it, we conducted a combined spectrometry/tractography/cognitive battery and psychopathological rating study on patients with treatment-resistant schizophrenia (TRS), dividing the sample into early-onset (N = 21) and adult-onset TRS (N = 20). Previous studies did not differentiate between early- (onset 13-18 years) and adult-onset (>18 years at formal diagnosis of schizophrenia) TRS. METHODS: We evaluated cross-sectionally 41 TRS patients (26 male and 15 female) and 20 matched healthy controls (HCs) with psychopathological and cognitive testing prior to participating in brain imaging scanning using magnetic resonance spectroscopy and diffusion tensor imaging to determine the relationship between their symptoms and their glutamate levels and white matter integrity. RESULTS: TRS patients scored lower than HCs on all cognitive domains; early-onset patients performed better than adult-onset patients only on the Symbol Coding domain. TRS correlated with symptom severity, especially negative symptoms. Glutamate levels and glutamate/creatine were increased in anterior cingulate cortex. Diffusion tensor imaging showed low fractional anisotropy in TRS patients in specific white matter tracts compared to HCs (bilateral anterior thalamic radiation, cortico-spinal tract, forceps minor, inferior fronto-occipital fasciculus, inferior longitudinal fasciculus, superior longitudinal fasciculus, and right uncinate fasciculus). CONCLUSIONS: We identified specific magnetic resonance spectroscopy and diffusion tensor imaging alterations in TRS patients. Adult-onset TRS differed little from early-onset TRS on most measures; this points to alterations being present since the outset of schizophrenia and may constitute a biological signature of treatment-resistance.

RESUMEN

BACKGROUND: Age-at-onset (AAO) affects psychiatric disorder outcome; substance (SUDs) or alcohol use disorders (AUDs) may influence their onset. Affective temperaments may affect early AAO and drug-use proneness. Objectives: To investigate whether SUD/AUD moderated temperamental effects in determining AAO of mental disorders. Methods: We included 300 post-acute inpatients with schizophrenia-spectrum and other psychotic (SSOPDs), major depressive (MDD) or bipolar (BD) disorders (168 men; mean age, 40.63 years ± 11.82 men, 43.21 years ± 12.69 women) with (N = 110) or without (N = 190) SUD/AUD. Patients completed cross-sectionally TEMPS-A. We carried moderation analysis with each regression-significant TEMPS temperament as independent variable, SUD/AUD presence/absence as dichotomous moderator, and AAO as dependent variable. Significance was set at p < 0.05. Results: AAO was lower in patients with SUD/AUD diagnosis than in patients without (23.74 ± 10.09 vs. 27.73 ± 10.35, respectively, p = 0.001, η2 = 0.034). SUD/AUD patients scored higher on the hyperthymic (10.22 ± 4.08, p < 0.001, η2 = 0.069) and irritable (8.26 ± 4.69, p < 0.01, η2 = 0.026) temperaments than nonSUD/AUD patients. Moderation analysis showed only direct effects of irritable (ß = -0.55, p < 0.005) and hyperthymic (ß = -0.95, p < 0.001) temperaments on AAO and no significant SUD/AUD and interaction effects. Limitations. Cross-sectional design. Conclusions: When irritable and hyperthymic traits prevail over other temperaments, AAO is earlier in SSOPDs, MDD, and BD. SUD/AUD presence/absence does not moderate the relationship between temperament and AAO.

RESUMEN

BACKGROUND: Major Depressive Episodes (MDEs) may characterise many psychiatric disorders. Its pharmacotherapy is laid with unmet needs, rendering the testing of new drugs necessary. OBJECTIVE: To compare the effects of vortioxetine with those of other antidepressants (OADs) in a 1-year naturalistic setting. METHODS: We included 126 adult patients with anMDE in the course of major depressive (MDD), bipolar (BD), or schizophrenia spectrum disorders (SSOPDs), with or without substance use disorder (SUD), who received 5-20 mg/day oral vortioxetine, and compared them with 100 patients receiving OADs at baseline and after 1, 3, 8, and 12 months on their scores on the MADRS, the CGIS, the 24-item BPRS, the YMRS, the Hamilton Anxiety Rating Scale, a Visual Analogue Scale for craving, the Columbia-Suicide Severity Rating Scale, and the WHOQOL-BREF. RESULTS: Patients on vortioxetine improved similarly to those on OADs on all measures, independently from having or not a comorbid SUD. However, they improved with time better than their OADcounterparts if affected by BD or SSOPDs, but not MDD, on the CGI-S, BPRS depression, anxiety, and manic symptoms. SUD hampered the response of anxiety to treatment. Men improved on depression with time better than women. CONCLUSION: MDEs responded to vortioxetine similarly to OADs by improving in depression, general psychopathology, anxiety, suicidal thinking, and quality-of-life, independently from SUD comorbidity. MDEs of patients with BD or SSOPDs on vortioxetine responded better than that of patients on OADs. Clinical Trial Registration No. 17354N.

RESUMEN

Background: Long-acting injectable (LAI) aripiprazole was found to be efficacious in schizophrenia. In common clinical practice, the use of LAIs is often restricted to chronic patients with frequent relapses and poor adherence. Recently, some investigators advanced the idea of early LAI use also in young people with schizophrenia at their first psychotic episode (FEP). Objective: Our study aimed to assess the effect of LAI aripiprazole once monthly (AOM) in the treatment of FEP in patients aged 18-26 years. Methods: We included 50 patients with DSM-5 schizophrenia as assessed with SCID, and used the Clinical Global Impressions Scale-Severity of Illness (CGI-S) and the Positive and Negative Syndrome Scale (PANSS) to assess symptom severity and the World Health Organization Quality of Life (WHOQOL), the Short Form Health Survey (SF-36) and the Personal and Social Performance Scale (PSP) to assess quality of life (QoL) and global health perception at baseline and 3, 6, 9, and 12 months after the first AOM injection. Results: AOM was associated with a progressive improvement, compared to baseline, of both positive (p < 0.001) and negative (p < 0.001) symptoms and in general psychopathology (p < 0.001) and decrease in global severity (p < 0.001). We also observed progressive improvement in QoL and social and personal functioning. Treatment adherence was 78% at study endpoint. Our results support that AOM may improve psychotic symptoms, QoL and social functioning in young FEP patients. Further studies should compare AOM to its oral formulation in the treatment of young patients with schizophrenia at the outset of their illness.

RESUMEN

BACKGROUND: To overcome nonadherence in patients with psychosis switch to long-acting injectable (LAI) antipsychotic formulations is adopted. Most oral versus LAI comparisons showed similar antipsychotic responses. Psychoses often overlap with substance use disorder (SUD). Head-to-head LAI comparisons have hitherto focused only on non-comorbid populations. OBJECTIVE: The objective of this study was to compare two LAIs, administered for 12 months, in initially hospitalized patients with psychosis comorbid with SUD in their clinical and quality of life (QoL) outcomes. PATIENTS AND METHODS: Inpatients were recruited during 2016 and switched randomly to 400 mg intramuscular aripiprazole monohydrate (AM) (N=50) or to 100 mg intramuscular paliperidone palmitate (PP) once-monthly (N=51); patients were discharged and followed up for 12 months. Patients were rated at baseline and after 1 year through the Clinical Global Impression scale - severity (CGIs), substance craving intensity was rated through a visual analog scale for substance craving, and QoL through the World Health Organization (WHOQOL-BREF) scale. We addressed confounders with backward stepwise logistic regression and three-way analysis of variance. RESULTS: PP were older and had more cases of schizophrenia spectrum and less bipolar disorders than AM, but AM had a stronger craving for substances at baseline. Both LAIs were associated with significant improvements in all outcomes, with AM displaying stronger effect sizes than PP. The two groups did not differ on baseline WHOQOL-BREF scores in any domain, but at the 1-year follow-up, AM fared better on all domains. The two groups did not differ in final severity, but PP scored higher than AM in craving at the 1-year endpoint.Limitation: The CGIs is not a refined tool for severity and the substance craving may be subject to recall bias. CONCLUSION: 1-year AM and PP was followed by improved clinical status and QoL and reduced substance craving in a population with psychosis and SUD comorbidity. AM, compared to PP, improved craving and QoL at the 1-year follow-up.

RESUMEN

Metabolic syndrome is associated with elevated morbidity and mortality for overt coronary artery disease (CAD). In diabetic patients, CAD is often silent. The relation between metabolic syndrome and silent CAD has never been studied. We investigated whether metabolic syndrome is associated with silent CAD in patients with type 2 diabetes mellitus. We evaluated the prevalence of metabolic syndrome in 169 patients with uncomplicated diabetes and angiographically verified silent CAD and in 158 diabetic patients without myocardial ischemia on exercise electrocardiography, 48-hours ambulatory electrocardiography, and stress echocardiography. The groups were comparable for gender, age, glycemic control, and diabetes duration. Metabolic syndrome was defined according to the National Cholesterol Education Program criteria. To estimate insulin resistance in patients treated with diet alone or oral agents (122 patients with CAD and 115 patients without CAD), the Homeostasis Model Insulin-Resistance Assessment (HOMA) was used. The prevalence of metabolic syndrome (59.8% vs 44.3%, p = 0.005) and HOMA (5.4 +/- 2.1 vs 4.9 +/- 2.8, p = 0.044) were significantly higher in those with CAD than in those without CAD. Multiple logistic regression analysis showed that the metabolic syndrome was associated with silent CAD (odds ratio 2.44, 95% confidence interval 1.19 to 5.02, p = 0.015). Among patients on diet alone or oral agents, the HOMA was the strongest predictor of silent CAD (odds ratio 10.16, 95% confidence interval 2.60 to 39.63, p < 0.001). In conclusion, our data have shown an independent association of metabolic syndrome and insulin resistance with silent CAD in patients with type 2 diabetes mellitus. Other studies are needed to establish whether metabolic syndrome and HOMA are reliable markers to identify diabetic patients for additional screening for silent CAD.

RESUMEN

BACKGROUND: Erectile dysfunction (ED) is associated with coronary artery disease (CAD). In diabetic patients, CAD is often silent. Among diabetic patients with silent CAD, the prevalence of ED has never been evaluated. We investigated whether ED is associated with asymptomatic CAD in type 2 diabetic patients. METHODS AND RESULTS: We evaluated the prevalence of ED in 133 uncomplicated diabetic men with angiographically verified silent CAD and in 127 diabetic men without myocardial ischemia at exercise ECG, 48-hour ambulatory ECG, and stress echocardiography. The groups were comparable for age and diabetes duration. Patients were screened for ED using the validated International Index of Erectile Function (IIEF-5) questionnaire. The prevalence of ED was significantly higher in patients with than in those without silent CAD (33.8% versus 4.7%; P=0.000). Multiple logistic regression analysis showed that ED, apolipoprotein(a) polymorphism, smoking, microalbuminuria, HDL, and LDL were significantly associated with silent CAD; among these risk factors, ED appeared to be the most efficient predictor of silent CAD (OR, 14.8; 95% CI, 3.8 to 56.9). CONCLUSIONS: Our study first shows a strong and independent association between ED and silent CAD in apparently uncomplicated type 2 diabetic patients. If our findings are confirmed, ED may become a potential marker to identify diabetic patients to screen for silent CAD. Moreover, the high prevalence of ED among diabetics with silent CAD suggests the need to perform an exercise ECG before starting a treatment for ED, especially in patients with additional cardiovascular risk factors.

RESUMEN

OBJECTIVE: In patients with uncomplicated diabetes, there is low probability of finding significant coronary artery disease (CAD) by noninvasive tests. Therefore, screening for its presence is not justified, and it is important to find reliable predictors of silent CAD to identify patients with uncomplicated diabetes for further screening. The relationship between lipoprotein(a) [Lp(a)], apolipoprotein(a) [apo(a)] polymorphism, and silent CAD has never been studied. We investigated the association of Lp(a) and apo(a) polymorphism with angiographically documented asymptomatic CAD in type 2 diabetic patients without evident complications. RESEARCH DESIGN AND METHODS: A total of 1,323 diabetic patients without any clinical and electrocardiographic evidence of CAD were evaluated. Of 121 patients with highly positive results of exercise electrocardiography (ECG) (n = 30) or positive results on exercise thallium scintigraphy (n = 91), 103 subjects showed angiographically documented CAD (CAD group). Of 1,106 patients with negative results on exercise ECG, 103 subjects without CAD (NO CAD group) were selected and matched by age, gender, and duration of diabetes to patients in the CAD group. In patients in the NO CAD group, results of exercise ECG, 48-h ambulatory ECG, and stress echocardiography were negative for CAD. RESULTS: The CAD group had higher Lp(a) levels (21.7 +/- 17.7 vs. 15.2 +/- 19.0 mg/dl; P = 0.0093) than the NO CAD group, and a percentage of subjects had at least one small apo(a) isoform (68.9 vs. 29.1%; P = 0.0000) higher than the NO CAD group. Logistic regression analysis showed that apo(a) phenotypes (odds ratio [OR] 8.13, 95% CI 3.65-21.23), microalbuminuria (5.38, 2.44-11.88), smoking (2.72, 1.31-5.64), and Lp(a) levels (2.41, 1.15-5.03) were predictors of asymptomatic CAD. CONCLUSIONS: Our investigation reports the first evidence of an independent association of Lp(a) and apo(a) polymorphism with asymptomatic CAD. This suggests that Lp(a) levels and apo(a) phenotypes could be used together with other risk factors as markers of asymptomatic CAD in patients with diabetes.

RESUMEN

BACKGROUND: The metabolic syndrome is a cluster of cardiovascular risk factors (central obesity, hypertension, dyslipidemia, disturbance in glucose metabolism) associated with insulin-resistance. The cluster of risk factors defining the metabolic syndrome increases cardiovascular risk more than each single component. The aim of the present longitudinal study was to evaluate the relationship between weight loss and changes in insulin-resistance and in the prevalence of the metabolic syndrome 1-year after SAGB implantation. METHODS: 51 premenopausal severely obese women (mean age 35.2 +/- 8.8 years, BMI 43.3 +/- 6.9) were enrolled. As a control group, 51 premenopausal non-obese women (BMI < 30) were enrolled. All obese subjects underwent successful implantation of the SAGB via videolaparoscopy. In all subjects insulin-resistance was estimated by HOMA index and metabolic syndrome was defined according to the criteria of the European Group for the Study of Insulin Resistance. RESULTS: HOMA (4.2 +/- 2.0 vs 1.9 +/- 0.8, P < 0.001) and the prevalence of the metabolic syndrome (58.8% vs 7.8%, P < 0.001) were significantly higher in obese than non-obese women. 1 year after SAGB, BMI significantly decreased from 43.3 +/- 6.9 to 34.5 +/- 7.4 (P < 0.001). HOMA index showed a significant dramatic breakdown (4.2 +/- 2.0 vs 2.4 +/- 1.0, P < 0.001). The prevalence of the metabolic syndrome declined significantly (58.8% vs 21.6%, P < 0.001). CONCLUSION: Our study shows that in severely obese women, insulin-resistance and the prevalence of the metabolic syndrome significantly decrease 1 year after SAGB. Our findings indicate that SAGB could be a useful tool to reduce the global cardiovascular risk in severely obese people and to improve their long-term prognosis.
