Cardiovascular risk in patients with severe mental illness in Italy

Background: Patients with severe mental illness (SMI), such as schizophrenia or bipolar disorders, are more frequently affected by metabolic syndrome and cardiovascular (CV) diseases than the general population, with a significant reduction in life expectancy. Beyond metabolic syndrome, quantifying the risk of CV morbidity in the long-term may help clinicians to put in place preventive strategies. In this study, we assessed 10-year CV risk in patients with SMI and healthy individuals using an algorithm validated on the Italian general population. Methods: Patients aged 35-69 years diagnosed with SMI were consecutively recruited from psychiatric acute care units. Single CV risk factors were assessed, and 10-year CV risk calculated by means of the CUORE Project 10-year CV risk algorithm, based on the combination of the following risk factors: age, systolic blood pressure, total and high-density lipoprotein cholesterol, diabetes, smoking habit, and hypertensive treatment. Patients' data were compared with those from the general population. The 10-year CV risk was log-transformed, and multivariable linear regression was used to estimate mean ratios, adjusting for age, and education. Results: Three hundred patients and 3,052 controls were included in the analysis. Among men, the 10-year CV risk score was very similar between patients with SMI and the general population (mean ratio [MR]: 1.02; 95%CI 0.77-1.37), whereas a 39% increase in 10-year CV risk was observed in women with SMI compared to the general population (MR: 1.39; 95%CI 1.16-1.66). Conclusions: In our study, women with SMI were consistently more at risk than the general population counterpart, even at younger age

Diverse definitions of the early course of schizophrenia - a targeted literature review

Schizophrenia is a debilitating psychiatric disorder and patients experience significant comorbidity, especially cognitive and psychosocial deficits, already at the onset of disease. Previous research suggests that treatment during the earlier stages of disease reduces disease burden, and that a longer time of untreated psychosis has a negative impact on treatment outcomes. A targeted literature review was conducted to gain insight into the definitions currently used to describe patients with a recent diagnosis of schizophrenia in the early course of disease ('early' schizophrenia). A total of 483 relevant English-language publications of clinical guidelines and studies were identified for inclusion after searches of MEDLINE, MEDLINE In-Process, relevant clinical trial databases and Google for records published between January 2005 and October 2015. The extracted data revealed a wide variety of terminology and definitions used to describe patients with 'early' or 'recent-onset' schizophrenia, with no apparent consensus. The most commonly used criteria to define patients with early schizophrenia included experience of their first episode of schizophrenia or disease duration of less than 1, 2 or 5 years. These varied definitions likely result in substantial disparities of patient populations between studies and variable population heterogeneity. Better agreement on the definition of early schizophrenia could aid interpretation and comparison of studies in this patient population and consensus on definitions should allow for better identification and management of schizophrenia patients in the early course of their disease

Brain metabolism in substance-induced psychosis and schizophrenia : a preliminary PET study

Introduction: The relation between schizophrenia and cannabis abuse has been widely discussed from etiopathogenetic, psychopathological and neurometabolic points of view. Relatively little has been written about the differences between schizophrenia with co-occurrent cannabis abuse and substance-induced psychotic disorder (SIPD). Given these premises, our study aims to investigate the psychopathological and neurometabolic features of these clinical entities. Methods: We enrolled patients experiencing an acute psychotic episode, affected either by schizophrenia with or without cannabis abuse (SCZ +/- CA; n = 5 and n = 5, respectively) with recent onset (<5 years of illness) or by SIPD (n = 6), as diagnosed by the Structured Clinical Interview for DSM-IV Axis I. Patients affected by SIPD were all cannabis abusers. All patients were assessed with the PANSS (Positive and Negative Scale for Schizophrenia), urinary toxicological tests and brain 18-FDG-PET scanning in resting condition. Statistical analysis (ANOVA) was performed with Statistical Parametric Mapping SPM8 and Scenium software. Results: Bilateral hypermetabolism in the posterior cingulum and the precuneus (p < 0.001) was observed in SIPD patients compared to patients with schizophrenia, with or without cannabis abuse. Conclusions: Our preliminary PET findings suggest that substance abuse may cause increased brain metabolism in patients with induced psychosis but not in those with schizophrenia. These differences in brain metabolism were found in the posterior cingulum and precuneus, which are two core regions of the default mode network in humans

Studio di correlazione tra variabili sintomatologiche, alessitimia e decorso clinico in pazienti con disturbo di panico in terapia integrata

Introduzione : numerosi studi si sono occupati di verificare l\u2019efficacia della terapia integrata, farmacologica e psicoterapeutica breve (PB) o cognitivo-comportamentale (CBT), nel disturbo di panico (DAP) per evidenziare quali tecniche possano favorire un migliore outcome clinico a lungo termine. Scopo del nostro studio \ue8 verificare eventuali correlazioni tra sintomatologia clinica, funzionamento mentale e decorso di malattia. Metodi : sono stati reclutati 20 pazienti all\u2019esordio di un DAP, diagnosticato secondo i criteri DSM-IV-TR. Tutti i pazienti sono stati trattati con SSRI e assegnati alla PB o CBT attraverso la \u201cblocking randomization\u201d(Consort, 2001). Sono state somministrate Panic Attack and Anticipatory Anxiety Scale (PAAAS), Hamilton Ansia e Depressione (HAM-A, D) per la valutazione sintomatologica, Mark-Sheehan Phobia Scale (MSPS) per il grado di evitamento e Toronto Alexithymia Scale-20 item (TAS-20) per l\u2019alessitimia. Risultati : l\u2019analisi bivariata (Spearman\u2019s correlations) ha evidenziato una correlazione tra il fattore F3 della TAS-20 (Pensiero orientato verso l\u2019esterno) e il punteggio totale alla PAAAS (r = 0,888, p = 0,044). Conclusioni : il nostro studio evidenzia come la presenza di una disregolazione nell\u2019elaborazione delle esperienze emotive e dei correlati cognitivi e somatici del DAP sia predittiva di una maggiore gravit\ue0 sintomatologica. Tale funzionamento mentale potrebbe quindi contribuire alla persistenza di una vulnerabilit\ue0 alla sintomatologia nel temp

Substance-induced psychoses : a critical review of the literature

Substances with psychotomimetic properties such as cocaine, amphetamines, hallucinogens and cannabis are widespread, and their use or abuse can provoke psychotic reactions resembling a primary psychotic disease. The recent escalating use of methamphetamine throughout the world and its association with psychotic symptoms in regular users has fuelled concerns. The use of cannabis and cocaine by young people has considerably increased over recent years, and age at first use has dramatically decreased. There is some evidence that cannabis is now on the market in a more potent form than in previous decades. Furthermore, a large number of studies have reported a link between adolescent cannabis use and the development of stable psychosis in early adulthood. The situation is further complicated by the high rates of concomitant substance use by subjects with a psychotic illness which, especially in young users with an early-phase psychotic disorder, can make diagnosis difficult. This paper reviews the literature concerning the properties of psychotogenic substances and the psychotic symptoms they can give rise to, and discusses the association between substance abuse and psychosis with particular emphasis on the differential diagnosis of a primary and substance-induced psychotic disorder. The findings of this review indicate that psychosis due to substance abuse is commonly observed in clinical practice. The propensity to develop psychosis seems to be a function of the severity of use and dependence. From a phenomenological point of view, it is possible to identify some elements that may help clinicians involved in differential diagnoses between primary and substance-induced psychoses. There remains a striking paucity of information on the outcomes, treatments, and best practices of substance-induced psychotic episodes

Number of episodes and duration of illness associated with hypertension and 10-year cardiovascular risk in patients with bipolar disorder type I

Severe Mental Illnesses, including bipolar disorder (BD) and schizophrenia (SCZ), are burdened with an increased mortality and a significantly reduced life expectancy than general population, and cardiovascular diseases (CVD) are considered the most contributing conditions. The aim of the present study is to evaluate 10-year CV risk and the associated clinical characteristics in patients with SCZ, BD type I and II. Patients were consecutively recruited from two Italian psychiatric acute units. Single CV risk factors were assessed, and 10-year CV risk calculated by means of the CUORE Project 10-year CV risk algorithm, based on the combination of the following risk factors: age, systolic blood pressure, total and high-density lipoprotein cholesterol, diabetes, smoking habit, and hypertensive treatment. Three hundred patients were included. Patients with BD type I showed a higher prevalence of hypertension and 10-year CV risk score compared to the other groups. In subjects with BD type I, we found a significant correlation between duration of illness and number of mood episodes and both hypertension and 10-year CV risk score. Several preventive strategies should be provided to these vulnerable populations, such as correcting unhealthy lifestyles, prescribing medications at lower CV and metabolic risk, enhancing access to care

Clinical pharmacology of atypical antipsychotics:An update

This review will concentrate on the clinical pharmacology, in particular pharmacodynamic data, related to atypical antipsychotics, clozapine, risperidone, paliperidone, olanzapine, quetiapine, amisulpride, ziprasidone, aripiprazole, asenapine, iloperidone, lurasidone and cariprazine. A summary of their acute pharmacokinetics properties are also reported. Four new second-generation antipsychotics are available: iloperidone, asenapine, lurasidone and in the next future cariprazine. Similar to ziprasidone and aripiprazole, these new agents are advisable for the lower propensity to give weight gain and metabolic abnormalities in comparison with older second-generation antipsychotics such as olanzapine or clozapine. Actually lurasidone seems to be best in terms of minimizing unwanted alterations in body weight and metabolic variables. Therapeutic drug monitoring is not strictly necessary for all of the new antipsychotic drugs because there are no unequivocal data supporting a relationship between plasma drug levels and clinical outcomes or side effects. The exception can be represented by clozapine for which plasma levels of 350-420 ng/ml are reported to be associated with an increased probability of a good clinical response. Also for olanzapine an established therapeutic range (20-50 ng/ml) is proposed to yield an optimal response and minimize side effects
