RESUMO

BACKGROUND: The aim of the current study was to examine the heterogeneity of functional outcomes in first episode psychosis (FEP) patients and related clinical, neurocognitive and sociodemographic factors using a cluster analytic approach. METHOD: A large sample of FEP patients (N = 209) was functionally reassessed 10 years after the first contact with an early intervention service. Multiple baseline, 3-year and 10-year follow-up variables were explored. RESULTS: The cluster analysis emphasized the existence of six independent clusters of functioning: one cluster was normal overall (42.16%), two clusters showed moderate interpersonal (9.63%) or instrumental (12.65%) deficits, two clusters showed more severe interpersonal (12.05%) or interpersonal and instrumental (13.85%) deficits and there was a significantly overall impaired cluster (9.63%). Cluster comparisons showed that several baseline and follow-up factors were differentially involved in functional outcomes. CONCLUSIONS: The current study demonstrated that distinct clusters of functioning in FEP patients can be identified. The fact that a variety of profiles was observed contributes to a better understanding of the nature of the heterogeneity characterizing FEP patients and has clinical implications for developing individualized treatment plans.

RESUMO

BACKGROUND: Low-grade inflammation has been repeatedly associated with both excess weight and psychosis. However, no previous studies have addressed the direct effect of body mass index (BMI) on basal serum cytokines in individuals with first-episode psychosis (FEP). OBJECTIVES: The aim of this study is to analyze the effect of BMI on basal serum cytokine levels in FEP patients and control subjects, separating the total sample into two groups: normal-weight and overweight individuals. METHODS: This is a prospective and open-label study. We selected 75 FEP patients and 75 healthy controls with similar characteristics to patients according to the following variables: sex, age, and cannabis and tobacco consumption. Both controls and patients were separated into two groups according to their BMI: subjects with a BMI under 25 were considered as normal weight and those with a BMI equal to or more than 25 were considered as overweight. Serum levels of 21 cytokines/chemokines were measured at baseline using the Human High Sensitivity T Cell Magnetic Bead Panel protocol from the Milliplex® Map Kit. We compared the basal serum levels of the 21 cytokines between control and patient groups according to their BMI. RESULTS: In the normal-weight group, IL-8 was the only cytokine that was higher in patients than in the control group (p = 0.001), whereas in the overweight group, serum levels of two pro-inflammatory cytokines (IL-6, p = 0.000; IL-1ß, p = 0.003), two chemokines (IL-8, p = 0.001; MIP-1ß, p = 0.001), four Th-1 and Th-2 cytokines (IL-13, p = 0.009; IL-2, p = 0.001; IL-7, p = 0.001; IL-12p70, p = 0.010), and one Type-3 cytokine (IL-23, p = 0.010) were higher in patients than in controls. CONCLUSIONS: Most differences in the basal serum cytokine levels between patients and healthy volunteers were found in the overweight group. These findings suggest that excess weight can alter the homeostasis of the immune system and therefore may have an additive pro-inflammatory effect on the one produced by psychosis in the central nervous system.

RESUMO

Relapses may represent a critical hazard in schizophrenia spectrum disorders as they are associated with an increased risk of a clinical and functional deterioration. Preventing relapse after recovering from a first psychotic episode has become a major challenge due to its critical impact on lifelong functionality. This study explored the rate of first and second relapses and the predictors associated with these relapses in a large cohort of non-affective psychosis patients during a period of 3 years after the first break of the illness. From February 2001 to May 2014, sociodemographic and clinical data from an epidemiological cohort of 341 non-affective first-episode psychosis patients at risk of relapse were analysed at a specialized early intervention service. Logistic regression, Cox regression, and Kaplan-Meier survival analyses were performed to compare non-relapsed and relapsed patients. One hundred and sixty-six (48.7%) individuals relapsed at least once. Median time to relapse was 17.0 months in non-adherent patients and 40.0 months in adherent patients (log-rankχ 2: 51.36; p < 0.001). Non-adherence to medication (odds ratio-OR 2.979; p < 0.001), schizophrenia diagnosis (OR 2.173; p = 0.002), and age of onset (OR 1.020; p = 0.033) were the main predictors of the first relapse. Fifty-six subjects experienced a second relapse (33.73%) predicted by diagnosis (OR 1.975; p = 0.074), age of onset (OR 1.078; p = 0.003), and positive symptoms (OR 0.863; p = 0.03), but not adherence. Non-adherence is the main predictive factor of first relapse after a first episode of psychosis. Second relapses were not often and not related to modifiable factors, suggesting that multiple relapsed patients may comprise a subgroup with a higher biological risk.

RESUMO

Data on the long-term metabolic side-effects associated with antipsychotics are scarce. Prospective longitudinal studies in medication-naive patients with a first episode of psychosis are a valuable source of information as they provide an assessment prior to the antipsychotic exposure and minimize the effect of potential confounding factors. The aim of this study was to assess the course of weight gain and the incidence of metabolic abnormalities during the first 3 yr of antipsychotic treatment. Data were collected from a cohort of 170 first-episode psychosis patients. They were randomly assigned to haloperidol (32%); olanzapine (32%) and risperidone (36%). The dose used was flexible. The initial antipsychotic treatment was changed when required, based on clinical response and tolerability. The results showed that the mean weight gain at 3 yr was 12.1 kg (s.d. = 10.7). It appeared to increase rapidly during the first year (85% of the total mean weight gain) and then stabilized gradually over time. Total cholesterol, LDL-cholesterol and triglyceride levels followed a similar trajectory with a significant increase only during the first year. No significant changes were detected in the mean values of glycaemic parameters. Two patients with a family history of diabetes developed diabetes type II. At short-term the factors positively associated with weight gain were lower body mass index, male gender and olanzapine treatment. At long-term, functional status and clinical response were the main predictors. The results of our study indicate that the first year of antipsychotic treatment is a critical period for weight gain and metabolic changes. Identification of weight gain patterns may help to inform studies that aim to prevent or mitigate the metabolic adverse events associated with antipsychotic therapy.

RESUMO

Differences among antipsychotics in effectiveness have turned out to be a topic of increasing research interest, although comparisons between the different second-generation antipsychotics are scarce. From October 2005 to March 2011, a prospective, randomized, open-label study comparing the effectiveness of aripiprazole, ziprasidone, and quetiapine in the short-term treatment of first-episode schizophrenia-spectrum disorders was undertaken. Two hundred two patients were randomly assigned to aripiprazole (n = 78), ziprasidone (n = 62), or quetiapine (n = 62) and followed up for 6 weeks. The primary effectiveness measure was all-cause of treatment discontinuation. In addition, an analysis based on per protocol populations was conducted in the analysis for clinical efficacy. The overall dropout rate at 6 weeks was small (6.4%). The treatment discontinuation rate differed significantly between treatment groups (aripiprazole, 15%; ziprasidone, 19%; and quetiapine, 35%; χ(2) = 8.529; P = 0.014). Insufficient efficacy in the group of quetiapine is the main reason for discontinuation rate differences (χ = 10.139; P = 0.006). The mean time to all-cause discontinuation was significantly different between the groups (log-rank, 12.783; P = 0.001). Quetiapine was associated with a greater depressive symptoms improvement than ziprasidone (P = 0.045). The rate of responders at 6 weeks differed between the groups (F = 6, 116; P = 0.047), with a higher rate of the responders with aripiprazole. The profile of adverse effects varies between the treatments. Patients on quetiapine were less likely to be prescribed concomitant medications. Treatment with quetiapine was associated with a higher risk of treatment discontinuation during treatment owing to insufficient efficacy. Differences in effectiveness between second-generation antipsychotics would determine their position in everyday clinical practice and could help physicians choose the more efficacious antipsychotics.

RESUMO

OBJECTIVE: The main goal of this study was to assess the long-term effect of haloperidol, olanzapine, and risperidone on serum prolactin levels in a naturalistically treated first-episode psychosis population. METHODS: Patients included in this study were drawn from a prospective, randomized, open-label clinical trial. Prolactin levels were measured in 110 patients with medication-naive first-episode psychosis at baseline, 3 months, and 1 year. RESULTS: A repeated-measures analysis of variance revealed a significant difference between treatments (F = 17.28, P < 0.001). At 1-year follow-up, most patients in the haloperidol and olanzapine arms had prolactin values that fell within the reference range. Patients treated with risperidone experienced a significant increase at 3 months resulting in prolactin levels above the reference range in 90% of men and 87% of women. The levels showed a tendency to decrease at 1 year, although still more than 70% of the values remained above the normative range. Sexual adverse drug reactions at 1 year assessed by the Udvalg for Kliniske Undersogelser scale showed that a higher percentage (39.3%) of patients had symptoms in the risperidone group compared to the olanzapine group (24%) or haloperidol group (20%), but the difference did not reach statistical significance (P = 0.281). CONCLUSION: Olanzapine and haloperidol treatments do not significantly affect serum prolactin levels at long term. After 1 year, elevated prolactin levels persist in most patients treated with risperidone.

RESUMO

In the last years, there has been growing evidence linking elevated homocysteine levels with cognitive dysfunction in several neurological and neuropsychiatric diseases. The aim of the present study was to investigate the potential relationship between elevated homocysteine levels and cognitive deficits in first-episode psychosis patients. Plasma levels and cognitive performance of 139 patients and 99 healthy volunteers were compared. Patients were classified as elevated homocysteine (>90 percentile for controls) and normal and compared on 22 cognitive outcome measures grouped into cognitive domains known to be impaired in schizophrenia. Patients had a statistically significant increase in plasmatic homocysteine levels. In addition, they presented with significantly increased cognitive deficits. However, no relationship between homocysteine levels and cognitive impairment was detected. These results suggest the need for further studies to clarify the role of homocysteine in the etiology and prognosis of psychosis.

RESUMO

Weight gain is one of the major adverse effects of antipsychotics. Although mechanisms remain unclear, genetic susceptibility has become increasingly attractive as a potential mechanism that could explain a significant part of interindividual variability. Most investigations have explored genes related with the mechanism of action of antipsychotic drugs. An alternative approach to investigate the role that genetic factors play in weight gain secondary to antipsychotic treatment is to study those genetic variants that have been found associated with obesity. The aim of this study was to determine whether the fat mass and obesity-associated gene (FTO) rs9939609 variant, the single nucleotide polymorphism that has shown the strongest association with common obesity in different populations, influences weight gain during the first year of antipsychotic treatment. We investigated also the genetic variants in other 3 strong candidates genes involved in the leptin-signaling pathway including leptin, leptin receptor, and Src homology 2. We carried out a prospective study on 239 patients with first-episode psychosis. Two hundred five patients completed the follow-up at 1 year (85.8%). Before antipsychotic treatment, the homozygous subjects for the risk allele A of the FTOrs9939609 variant had a higher body mass index at baseline (24.2 T 3.8 kg/m²) than the AT/TT group (22.82 T 3.3 kg/m2; F = 5.744; P = 0.018). After 1 year, the magnitude of weight increase was similar in the 3 genotypes defined by the rs9939609 variant. These results suggest that the pharmacological intervention accompanied by changes in energy intake and expenditure could suppress the genetic susceptibility conferred by the FTO genotype. None of the other single nucleotide polymorphisms evaluated were associated with weight gain during the first 12 months of antipsychotic therapy.

RESUMO

The present study aimed to examine the levels and interactions of family burden (FB) and expressed emotion (EE) in first episode psychosis (FEP) patients and, secondly, to observe the potential change after a brief psychoeducational group intervention implemented in a real world clinical setting. Twenty-three key relatives of FEP patients received a brief psychoeducational group intervention. FB and EE were assessed before and after the intervention. EE-change and correlations between variables were examined. Half of the sample of key-relatives showed high levels of EE. No severe family burden was observed. FB and EE did not change after the intervention. Family subjective and objective burden were correlated with emotional overinvolvement, but not with criticism. Brief psychoeducational groups may not be sufficient to reduce FB and EE associated to the experience of caregiving for a family member with a first-episode psychotic disorder.

RESUMO

OBJECTIVE: This study examined the main metabolic side effects induced by antipsychotic treatment in a cohort of first episode drug-naïve subjects after the first year of treatment. METHODS: A randomized, open-label, prospective clinical trial was conducted. Participants were 164 consecutive subjects included in a first episode program and never treated with antipsychotic medication. Patients were assigned to haloperidol, olanzapine or risperidone. The main outcome measures were changes at 1 year in fasting glucose parameters (glucose, insulin levels and insulin resistance index) and changes in fasting lipid parameters (total cholesterol, triglycerides, LDL cholesterol, HDL cholesterol). RESULTS: 144 of the total sample were evaluated at 1 year. There was a statistically significant increase in the mean values of insulin levels, insulin resistance index, total cholesterol, LDL-cholesterol and triglycerides. No pathological values in fasting glucose plasma levels were found at baseline and there were no changes after 1 year. Weight gain was positively correlated with changes in insulin levels, insulin resistance index and triglyceride levels. We did not detect statistically significant differences between treatments in any of the parameters evaluated. CONCLUSIONS: Fasting glycaemia and insulin concentrations at baseline do not support the hypothesis that schizophrenia is associated with an underlying abnormality in glucose metabolism. The changes in insulin and lipid parameters at 1 year seem to be related to the magnitude of weight gain. There were no significant differences between haloperidol, olanzapine and risperidone concerning metabolic adverse effects after the first year of treatment.

RESUMO

BACKGROUND: There is little information about weight gain induced by antipsychotics at long-term. OBJECTIVE: To quantify the weight gain induced by first (haloperidol) and second generation antipsychotics (olanzapine and risperidone) in a cohort of drug-naïve subjects after 1 year of treatment. METHODS: This is a prospective, randomized clinical trial, including a representative sample of first episode psychotic incident cases from a population area of 555.000 people. The main outcome measures were changes in body weight and body mass index at 3 months and at 12 months. Both a per protocol analysis and an intention to treat analysis were conducted. RESULTS: A total of 164 drug-naïve patients were included. At 12 months 144 patients were evaluated. Of them, 66% completed the protocol and 34% needed treatment switch. We found statistically significant differences in weight gain at 3 months: 3.8 kg (+/-4.1) for haloperidol, 5.9 kg (+/-5.1) for risperidone and 8.4 kg (+/-5.0) for olanzapine (F=7.045; p=0.002). After 1 year the difference in weight gain had disappeared: 9.7 kg (+/-5.7) for haloperidol, 8.9 kg (+/-8.8) for risperidone and 10.9 kg (+/-7.2) for olanzapine (F=0.817; p=0.445). CONCLUSIONS: Drug-naïve patients experience an extraordinary weight gain after 1 year of treatment with haloperidol, olanzapine or risperidone. The main difference among these treatments is the pattern of weight gain but not the final amount of weight gain.

RESUMO

BACKGROUND: In recent years, the effects of cannabis use on cognitive functions in patients with psychosis have been widely studied. Recently, special emphasis has been placed on the impact of age at the onset of consumption on cognition in these patients. METHOD: 349 patients with a first episode of non-affective psychosis were studied. Patients were classified as cannabis users and non-users. Users were divided, according to their age when they began using cannabis, into: early-onset (age < 16) and late-onset (age ≥ 16) users. Differences between groups at baseline were studied based on sociodemographic, clinical, and cognitive variables. The groups were longitudinally (3-year) compared on cognitive variables. RESULTS: Out of the 349 patients included in this study, 38.7% (N = 135) were cannabis users. Of them, 39.3% (N = 53) were early-onset and 60.7% (N = 82) were late-onset cannabis users. No baseline differences were found between the early-onset and late-onset groups on cognitive domains. Longitudinally, only patients who had withdrawn from cannabis use during follow-up showed a significant improvement in verbal memory. CONCLUSION: Our results did not show differences between the early-onset group and the other two groups in long-term cognitive performance, even if they kept consuming cannabis during the first three years of disease progression. Further studies are needed to elucidate the true relationship between early-onset cannabis use and cognitive function in patients with a first episode of psychosis.

RESUMO

INTRODUCTION: Evidence about the anti-inflammatory properties of antipsychotics has grown. However, no previous studies have compared the immunomodulatory effect of risperidone and aripiprazole. OBJECTIVES: The main aim of the present work is to compare the anti-inflammatory effect of risperidone and aripiprazole on a large array of serum cytokines at 3 months following the onset of treatment. METHODS: This is a prospective, randomized, open-label study. Patients were randomly assigned to risperidone or aripiprazole. From this randomization, 75 patients and 75 healthy volunteers that matched with the selected patients were picked for entry in this study. Serum concentrations of 21 cytokines/chemokines were measured at baseline and 3 months following the initiation of antipsychotic medication. RESULTS: Those patients who were randomly assigned to risperidone had higher levels of IL-8 (p = 0.000) and MIP-1ß (p = 0.007) than healthy volunteers at baseline, whereas no differences were found between patients initially assigned to aripiprazole and healthy volunteers. Three months following the onset of medication several cytokines decreased significantly: IL-8, MIP-1ß, Fractalkine, TNF-α, IL-7, IL-13, IL-17α, IL-23, IL-21 (all ps < 0.01). No differences were found in the percentages of change between both treatments. The effect size of the two antipsychotics was similar, except for TNF-α, IL-13, IL-17α and Fractalkine, in which aripiprazole seems to have a greater effect size than risperidone, whereas risperidone seems to have a greater effect size than aripiprazole on MIP-1ß. CONCLUSIONS: This is the first study that has compared the immunomodulatory effect of risperidone and aripiprazole, finding that the anti-inflammatory effect of both treatments was similar.

RESUMO

Approximately 60% of patients with a first episode of psychosis will significantly reduce the severity of their positive symptomatology with antipsychotic drugs. The aim of this study was to investigate predictors of response to antipsychotic treatment during the first episode of non-affective psychosis. 172 patients (107 male) with a diagnosis of schizophreniform, schizophrenia, schizoaffective, brief reactive psychosis, schizotypal personality disorder or psychosis non-otherwise specified entered the study. Sociodemographic, premorbid and clinical data at baseline were evaluated. Unpaired t-test for continuous and chi2 for categorical data, respectively, were used to compare responders and non-responders selected variables. Multivariate logistic regression was used to establish a prediction model. 57.6% of study subjects (99 of 172) responded to antipsychotic treatment. The following variables were significantly associated with less likelihood of response: 1.--lower severity of general psychopathology, positive symptoms and disorganized symptoms at baseline; 2.--earlier age of onset; 3.--diagnosis of schizophrenia; 4.--longer DUP; 5.--poorer premorbid adjustment during adolescence, and 6.--hospitalization. Multivariate logistic regression demonstrated that differences between responders and non-responders were largely accounted for by BPRS total score, age of onset, premorbid adjustment at early adolescence, and diagnosis. Patients with an early age of onset of schizophrenia, a poor premorbid adolescent functioning, and with a lower severity of psychopathology at intake seem to have a decrease likelihood of responding to antipsychotic treatment. Helping clinicians to identify non-responders is meant as a first step to optimise therapeutic effort to benefit individuals in this vulnerable group.

RESUMO

INTRODUCTION: Acute akathisia is a neuropsychiatric syndrome with a negative effect on illness outcome. Its incidence in patients treated with antipsychotics has shown to be highly variable across studies. OBJECTIVES: Our goals were to investigate prevalence, risk factors for the development of acute akathisia, and differences in incidence between antipsychotics in a sample of 493 first episode non-affective psychosis patients. METHODS: This is a pooled analysis of three prospective, randomized, flexible-dose, and open-label clinical trials. Patients were randomized assigned to different arms of treatment (haloperidol, quetiapine, olanzapine, ziprasidone, risperidone, or aripiprazole). Akathisia was determined using the Barnes Akathisia Scale at 6 weeks after antipsychotic initialization. Univariate analyses were performed to identify demographic, biochemical, substance use, clinical, and treatment-related predictors of acute akathisia. Considering these results, a predictive model based of a subsample of 132 patients was constructed with akathisia as the dependent variable. RESULTS: The overall incidence of akathisia was 19.5%. No differences in demographic, biochemical, substance use, and clinical variables were found. Significant incidence differences between antipsychotics were observed (Χ 2 = 68.21, p = 0.000): haloperidol (57%), risperidone (20%), aripiprazole (18.2%), ziprasidone (17.2%), olanzapine (3.6%), and quetiapine (3.5%). The predictive model showed that the type of antipsychotic (OR = 21.3, p = 0.000), need for hospitalization (OR = 2.6, p = 0.05), and BPRS total score at baseline (OR = 1.05, p = 0.03) may help to predict akathisia emergence. CONCLUSIONS: Among second generation antipsychotics, only olanzapine and quetiapine should be considered as akathisia-sparing drugs. The type of antipsychotic, having been hospitalized, and a more severe symptomatology at intake seem to predict the development of acute akathisia.

RESUMO

BACKGROUND: The purpose of this study was to compare an early behavioral intervention (EBI) with nonstructured standard physical care (routine care intervention [RCI]) in preventing antipsychotic-induced weight gain in drug-naive first-episode psychosis patients. METHOD: Sixty-one patients with a DSM-IV-diagnosed psychotic disorder were first randomly assigned to 3 different antipsychotic treatments (risperidone [N = 23], olanzapine [N = 18], and haloperidol [N = 21]) and subsequently randomly assigned to the intervention condition (EBI, N = 35) or RCI (N = 27). EBI was specifically designed to teach strategies to enhance control over factors associated with antipsychotic-induced weight gain and consisted of 8 flexible intervention modules that incorporated behavioral interventions, nutrition, and exercise. In the RCI group, patients were informed about potential weight gain and advised to increase their exercise and limit food intake. Body weight and body mass index were measured at baseline and then weekly for 3 months. In addition to change in weight and body mass index, a third outcome measure was the proportion of patients who had gained more than 7% of their body weight at 3 months. Participating patients were referred between August 2002 and September 2004. RESULTS: All 61 participants completed the study. Patients in the EBI group gained significantly less weight (mean = 4.1 kg, SD = 4.0) than those allocated to the RCI group (mean = 6.9 kg, SD = 4.5) (p < .01) during the 3-month follow-up period. Similar findings were obtained when both groups were compared on treatment-induced change in body mass index, which was significantly less in the EBI group than in the RCI group (1.40 vs. 2.39 kg/m2) (p < .01). Accordingly, significantly fewer patients in the EBI group (N = 11; 39.3%) than in the RCI group (N = 26; 78.8%) (p < .002) increased their baseline weight by more than 7%, the cutoff for clinically meaningful weight gain. CONCLUSIONS: EBI was effective in attenuating antipsychotic-induced weight gain in a drug-naive first-episode psychosis cohort. Patients displayed good adherence to this type of preventive intervention.

RESUMO

OBJECTIVE: The timing of antipsychotic discontinuation in patients who have fully recovered from their initial episode of psychosis is still open to discussion. We aimed to evaluate the risk of symptom recurrence during the 3 years after antipsychotic discontinuation in a sample of functionally recovered first-episode nonaffective psychosis (FEP) patients (DSM-IV criteria) with schizophrenia spectrum disorder. METHOD: Participants in this open-label, nonrandomized, prospective study were drawn from an ongoing longitudinal intervention program of FEP from a university hospital setting in Spain. From July 2004 to February 2011, functionally recovered FEP individuals were eligible if they met the inclusion criteria of (1) a minimum of 18 months on antipsychotic treatment, (2) clinical remission for at least 12 months, (3) functional recovery for at least 6 months, and (4) stabilization at the lowest effective doses for at least 3 months. Forty-six individuals who were willing to discontinue medication were included in the discontinuation group (target group). Twenty-two individuals opted to stay on the prescribed antipsychotic medication and therefore were included in the maintenance group (control group). Primary outcome measures were relapse rate at 18 and 36 months and time to relapse. RESULTS: The rates of relapse over the 3-year period were 67.4% (31 of 46) in the discontinuation group and 31.8% (7 of 22) in the maintenance group. The mean time to relapse was 209 (median = 122) days and 608 (median = 607) days, respectively (log rank = 10.106, P = .001). The resumption of antipsychotic medication after the relapse occurred was associated with clinical stability and lack of further relapses. When the overall group of relapsed individuals from the 2 conditions (N = 38) was compared to those who remained asymptomatic after 3 years (N = 30), there were significant differences (P < .05) in total scores on the Scale for the Assessment of Negative Symptoms, the Clinical Global Impressions scale, and the Disability Assessment Schedule. CONCLUSIONS: Antipsychotic treatment discontinuation in individuals who had accomplished a functional recovery after a single psychotic episode was associated with a high risk of symptom recurrence. Relapsed individuals had a greater severity of symptoms and lower functional status after 3 years. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT02220504.

RESUMO

RATIONALE: Patients with schizophrenia spectrum disorders have increased morbidity and mortality, largely due to cardiovascular disease, which is associated with antipsychotic treatment. OBJECTIVES: Because of the link between cardiometabolic risk, non-alcoholic fatty liver disease (NAFLD), and antipsychotics, we aimed to investigate the development of NAFLD during the first 3 years of antipsychotic treatment in first episode non-affective psychosis patients. RESULTS: A sample of 191 subjects was included in final analyses, randomly assigned to aripiprazole (N = 83), risperidone (N = 12), quetiapine (N = 46), and ziprasidone (N = 50). At intake, 180 patients were antipsychotic naïve. The NAFLD fibrosis score, FIB-4 score, and the fatty liver index (FLI) were calculated at baseline, at 3 months, and then yearly for 3 years. None of the patients showed significant liver fibrosis according to the mentioned scores at baseline, prior to randomization. At 3 years follow-up, 25.1 % individuals showed a FLI score ≥60, which is a predictor of steatosis. Of the individuals considered indeterminate at baseline, 64.7 % developed a FLI score ≥60 and only 16.6 % who had a FLI score <30 at baseline, showed a FLI score predictor of steatosis at endpoint. The FLI score ≥60 at endpoint was associated with an increase of more than 7 % of the body mass index (FLI score ≥ 60, 91.7 %; FLI < 60, 55.9 %; p < 0.001), increased triglyceride levels (FLI score ≥ 60, 54.2 %; FLI < 60, 5.6 %; p < 0.001), decreased HDL levels (FLI score ≥ 60, 41.7 %; FLI < 60, 17.5 %; p = 0.001), hypertension (FLI score ≥ 60, 19.5 %; FLI < 60, 4.5 %; p = 0.002), and waist circumference increase (steatosis 68.8 %; FLI < 60, 14.0 %; p < 0.001). CONCLUSIONS: Our results support the importance of assessing the potential development of NAFLD in schizophrenia spectrum patients receiving antipsychotic medication.

RESUMO

An increasing number of studies have focused on cognitive insight (i.e. awareness of one's own thinking) in psychotic disorders. However, little is known about the premorbid and pretreatment correlates of cognitive insight in the early course of psychosis. One hundred and three patients experiencing first-episode psychosis (FEP) were assessed shortly after treatment initiation for cognitive insight. Pretreatment and baseline clinical, functional and neurocognitive characteristics were examined. The self-reflectiveness dimension of cognitive insight was independently associated with clinical insight and executive functioning, whereas self-certainty was associated with premorbid IQ, premorbid academic adjustment and clinical insight. The amount of variance explained by the independent variables was small to moderate. Self-reflectiveness and self-certainty have differential pretreatment correlates in FEP and may reflect separate cognitive processes which require targeted interventions.
