Abstract
This multicentric randomized controlled trial (RCT), carried out in six Italian University mental health sites, aims to test the efficacy of a six-month psychosocial intervention (LYFESTYLE) on Body Mass Index (BMI), body weight, waist circumference, fasting glucose, triglycerides, cholesterol, Framingham and HOmeostasis Model Assessment of insulin resistance (HOMA-IR) indexes in patients with schizophrenia, bipolar disorder, and major depression. Moreover, the efficacy of the intervention has also been tested on several other physical and mental health domains. Patients were randomly allocated to receive the six-month experimental intervention (LIFESTYLE) or a behavioural control intervention. All enrolled patients were assessed at baseline and after one year. We recruited 401 patients (206 in the experimental and 195 in the control group) with a diagnosis of schizophrenia or other psychotic disorder (29.9%), bipolar disorder (43.3%), or major depression (26.9%). At one year, patients receiving the experimental intervention reported an improvement in body mass index, body weight, waist circumference, HOMA-IR index, anxiety and depressive symptoms and in quality of life. Our findings confirm the efficacy of the LIFESTYLE intervention in improving physical and mental health-related outcomes in patients with severe mental illnesses after one year.

Abstract
Introduction Many forms of mental disorders, especially psychotic disorders are characterized also by a worsening of sexual functioning. Sexual dysfunction has been shown to significantly correlate with a longer duration of untreated psychosis and with heavier psychotic symptomatology. Objectives The aim of this study is to validate the Italian version of the Arizona Sexual Experience (ASEX), a very handy and reliable tool to assess sexual dysfunction, in a population of people suffering from psychotic spectrum disorders. Methods Seventy-three psychiatric patients were recruited and assessed for mental illness and sexual functioning. We administered the Italian version of ASEX, adequately translated by two expert bilinguals. After 15 days we administered once again the test for test-retest reliability. Results Validation of ASEX revealed Cronbach’s coefficients >0.70 in both single items as in the total score. In addition, the test-retest reliability revealed Pearson’s coefficients >0.50 in the various domains. Confirmatory factor analysis revealed good fit indexes for the two factors model of ASEX (SRMR=0.54; CFI=0.974; RMSEA=0.135). Conclusions
This study represents the first validation in the Italian psychiatric context of a very useful specific tool for the sexual assessment in people suffering from mental illness. Our analysis revealed good psychometric characteristics in terms of confirmatory factor analysis, internal consistency, and test-retest reliability. Disclosure No significant relationships.

Abstract
Introduction A few studies have analyzed the impact of COVID-19 pandemic on psychiatric Emergency Department (ED) accesses. The pandemic may indeed have influenced the phase of day accesses for patients with psychiatric disorders. Objectives Aim of this cross-sectional study is to analyze how COVID-19 weighed on psychiatric patients daily accesses over the course of three years. Methods Data on 219 patients were retrospectively collected from the ED in the Policlinico Tor Vergata, Rome. According to the stage of the day, accesses were divided into 4 groups: between 00:00 and 6:00; between 6:00 a.m. and 12:00 a.m.; between 12:00 a.m. and 18:00 p.m.; between 18:00 p.m. and 00:00 p.m. Results Performing a regression analysis, a relation was found between psychiatric symptoms, stage of the day admission and year. In 2019 the admissions seem to be homogeneously distributed, however during 2021 and 2020 the admissions rates have a delayed evening trend. Conclusions Despite the low number of accesses considered, the Covid-19 pandemic appears to exert an effect that still lasts in terms of both accesses and worsening or new onset of psychiatric symptoms. Measures taken to prevent the spread of infections may have affected access in the ED of patients in various ways. However, the trend of increasing evening accesses could be related to a saturation of territorial psychiatric services that work mainly until the afternoon. Thus, an enhancement of territorial psychiatric services seems highly necessary to cope with what could be an increase in psychopathology in patients without previous diagnosis.

Abstract
Introduction
Several studies highlighted how COVID-19-related isolation and quarantine deeply weighed on the mental health of both the general and psychiatric population. There has been limited investigation about self-harm and impulsivity during the COVID-19 pandemic.
Objectives
The aim of this study is to evaluate how COVID-19-related lockdown affected self-harm rates in an Italian hospital.
Methods
Data on 59 patients were retrospectively collected from the Emercency deparment of the Policlinico Tor Vergata, Rome, from March 11 to May 4, 2020 (Italian mass quarantine) and the same periods of 2019 and 2021. Demographics, psychiatric history, substance use/abuse, types of self-harm and admission in psychiatric acute unit (PAU) rates were recorded.
Results
No statistical difference was reported in self-harm rates [9.8%(26/266) in 2019 vs 13.2%(10/76) in 2020 vs 10.7%(23/215) in 2021;p>0.05]. In 2020 subjects were younger (31.9±12.1 vs 39.2±14.4,p=0.22;vs 38.1±14.4;p=0.15) and had higher incidence of psychiatric history [90%(9/10) vs 73.1%(19/26), p=0.42;vs 65.2% (15/23),p=0.29],than 2019 and 2021 respectively. Substance use/abuse rates were significantly lower in 2020 compared to 2019 and 2021 [10%(1/10) vs 53.8%(14/26),p=0.04;vs 60.9% (14/23), p=0.02]. In 2020, subjects committing self-harms were more frequently admitted to PAU compared to 2019 and 2021 [60%(6/10)vs19.2%(5/26),p=0.04; vs 17.4% (4/23), p=0.04).
Conclusions
Consistent with the literature, lockdown-related measures negatively impacted on younger people, with higher rates of self-harm between March and May 2020. This, together with a higher rate of admissions to PAU, should warn the mental health system to target with specific programs to support adolescents and youngers.

Abstract
Background:Psoriatic Arthritis (PsA) is a chronic inflammatory disease characterized by a condition of inflammation of joint and periarticular tissues with progressive destruction of bone and cartilage tissues and consequent disability. Numerous studies suggest that the systemic inflammation that characterizes this disease is the basis of the onset of numerous comorbidities, including anxiety and depression.Objectives:This prospective study aims to examine the psychometric profile of patients with chronic inflammatory arthritis to investigate possible correlations with psychiatric comorbidities and disease status.Methods:from October 2018 to March 2019, consecutive out-patients with PsA (according to CASPAR criteria) referred to the Rheumatology Unit of the University of Rome Tor Vergata, were evaluated by a dedicated psychiatrist for attachment style (Relationship Questionnaire - RQ), alexithymia (Toronto Alexithymia Scale - TAS20), perceived stress (Perceived Stress Scale - PSS) and depressive symptoms (Beck Depression Inventory - BDI). These indices were then correlated with clinimetric indices, indices of inflammation and therapy taken by the patient. Statistical analysis was performed using Fisher’s exact test and Pearson’s correlation coefficient.Results:33 patients affected by PsA and 40 healthy individuals as control group were enrolled. The RQ test showed that in patients an insecure “avoidant” attachment style prevails (51.5%) compared to the control group (10%) (p<0.0008)[Figure 1]. This result correlates with the presence of alexithymia and with the duration of illness, showing that patients with an “insecure” profile at the RQ test are those who have higher scores on the TAS-20 scale (p=0.035) and a longer duration of illness (p<0.0001). Regarding the perception of stress, at the PSS test women have mean values (18.12±7.31) statistically superior to the values of the male population (11.69±7.79)(p=0.0015). PSS values of the overall study population were directly proportional to RQ values (p<0.0068) and TAS-20 values (p<0.0001). The correlation between PSS and TAS-20 was further confirmed in the analysis of the individual subgroups “patients” (p<0.0001) and control group (p<0.0001)[Figure 2]. No correlation was shown with phlogosis and clinimetric indices.Conclusion:This study suggests how PsA patients are a more vulnerable subtype of patient from the psychological point of view, with an avoidant attachment style, characterized by the difficulty to express emotions and to rely on others in times of need. These characteristics can influence the adherence to pharmacological therapies and the doctor-patient relationship. This profile is manifested more frequently in female patients, with long duration of illness, high perception of stress. The state of disease activity does not influence these elements, suggesting that the insecure attachment style is not related to the single inflammatory flare, but is the result of years of illness and long-standing disease. Our results support the relevance of early diagnosis in PsA.Disclosure of Interests:None declared

Abstract
Introduction Amongst different subtypes of Conversion Disorder (CD), DSM-V lists the Psychogenic Non-epileptic seizures (PNES). PNES are defined as episodes that visually resemble epileptic seizures but, etiologically, they are not due to electrical discharges in the brain. Objectives Our study aims to explore the differences between PNES and other CDs. In particular, we studied the suicidality and its correlations with dissociation and alexithymia. Methods Patients, recruited from the Psychiatry and Clinical Psychology Unit of the Fondazione Policlinico Tor Vergata, Rome, Italy, were diagnosed with PNES (n=22) and CD (n=16) using the DSM-5 criteria. Patients underwent the following clinical assessments: HAM-D, BDI, DES, BHS, TAS, CTQ. Results PNES showed significantly higher scores than CD in all assessments, except for BDI-somatic (p=0.39), BHS-feeling (p=0.86), and the presence of childhood trauma. PNES also showed significantly higher suicidality (p = 0.003). By controlling for the confounding factor “depression”, in PNES suicidality (and in particular the BHS-loss of motivation) appears to be correlated with DES-total score (p = 0.008), DES-amnesia (p = 0.002) and DES -derealization-depersonalization (p = 0.003). On the other hand, in CDs, the BHS-total score shows a correlation with the TAS-total score (p = 0.03) and BHS-Feelings with TAS-Externally-Oriented Thinking (p = 0.035), while only the BHS-Loss of motivation appears correlated with DES-Absorption (p = 0.011). Conclusions Our study shows significant differences between PNES and CD, in several symptomatologic dimensions, including suicidality. Indeed, in PNES suicidality appears to be related to dissociation, while in CDs it appears mainly to be correlated with alexithymia.

Abstract
IntroductionInternational Classification of Diseases 11th Revision (ICD-11) has inserted complex post-traumatic stress disorder (cPTSD) as a clinically distinct disorder, different from PTSD. The diagnosis of cPTSD has the same requirements for the one of PTSD, in addition to disturbances of self-organization (DSO – e.g., disturbances in relationships, affect dysregulation, and negative self-concept).ObjectivesThis study aimed to explore suicidality in PTSD and cPTSD. We examined also the association between clinical dimensions of hopelessness (feelings, loss of motivation, future expectations) and other symptomatologic variables.MethodsThe sample, recruited at the Fondazione Policlinico Tor Vergata, Rome, Italy, consisted of 189 subjects, 132 diagnosed with PTSD, and 57 with cPTSD, according to the ICD-11 criteria. Participants underwent the following clinical assessments: Clinician-Administered PTSD Scale (CAPS), Impact of Event Scale-Revised (IES), Beck Depression Inventory (BDI), Symptom Checklist-90-Revised (SCL-90), Dissociative Experience Scale (DES), Beck Hopelessness Scale (BHS).ResultscPTSD showed significantly higher BHS-total (p = 0.01) and BHS-loss of motivation subscale (p <0.001) scores than PTSD. Besides, cPTSD showed significantly higher scores in all clinical variables except for the IES-intrusive subscale. By controlling for the confounding factor “depression”, suicidality in cPTSD (and in particular the BHS-total) appears to be correlated with IES-total score (p = 0.042) and with DES-Absorption (p = 0.02). Differently, no such correlations are found in PTSD.ConclusionsOur study shows significant symptomatologic differences between PTSD and cPTSD, including suicidality. Indeed, suicidality in cPTSD appears to be correlated with the “loss of motivation” dimension, which fits well within the ICD-11 criteria of DSO.DisclosureNo significant relationships.

Abstract
Introduction Cognitive function is impaired in depressive disorders. Among several factors implicated in regulation of the cognitive function, metabolic syndrome has been showed have a pivotal role cognitive functioning in healthy controls. However, the role of metabolic syndrome in regulating the cognitive functioning of subjects affected by depressive disorders is little studied. Objectives To investigate the effect of metabolic syndrome in regulation of cognition in unipolar and bipolar depression. Methods One-hundred-sixty-five people affected by a depressive disorder (unipolar depression, UP; bipolar depression, BP) were enrolled at the Psychiatric and Clinic Psychology Unit of the University of Rome Tor Vergata, Rome, Italy. A group of healthy controls (HC) matched for agender and age was enrolled. The cognitive functions were evaluated with a computerized tool, THINC-it. Results UP and BP had lower performances in THINC-it cognitive domains than HC. Metabolic syndrome is a negative, independent predictor of low performance in the THINC-it cognitive domains of people with depressive disorders. Conclusions Our findings confirm that metabolic syndrome has a prominent role in determining the cognitive efficiency in depressive disorders, independently by the presence of a unipolar or bipolar depressive disorder. Metabolic syndrome has to be considered a major factor that should be considered in the treatment strategies of cognitive functioning improvement of people affected by depressive disorders.

Abstract
Introduction The deficiency of polyunsaturated fatty acids (PUFAs) and an alteration between the ratio of omega-6 and omega-3 PUFAs may contribute to the pathogenesis of depressive disorders. Objectives To investigate the levels of omega-3 and omega-6 in red cell membranes (mPUFAs) and plasma (pPUFAs) of patients with treatment-resistant (TRD) and non-treatment resistant depression (non-TRD). Methods TRD and non-TRD consisted of 75 patients enrolled at the Psychiatric and Clinic Psychology Unit of the University of Rome Tor Vergata, Rome, Italy, and met the DSM-IV criteria for major depressive disorder (MDD). A group of healthy controls (HC) matched for agender and age was enrolled. All blood samples were performed in conditions of an empty stomach between 07:00 am and 09:00 am. For each subject were obtained 5 ml of whole blood with the use of tubes for plasma with EDTA as an anticoagulant. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) for omega-3 and arachidonic acid (AA) for omega-6 were measured. Results Levels of pPUFAs did not differ between the three groups. The mPUFAs were altered in the MDD. TRD and non-TRD had lower EPA and AA values respect to the HC. DHA in red cell membranes was lower in TRD than non-TRD and HC. Conclusions Changes in levels of PUFAs in red cell membranes, but not in plasma, may be an important factor to evaluate the resistance to the pharmacological treatment.

Abstract
IntroductionSexual dysfunctions are frequent in patients with mental illnesses. In particular, anxious and depressive symptomatology often impacts on sexual functioning.ObjectivesThe aim of this study was to evaluate the relationship between sexual function and psychological symptoms in a group of male patients with depression and anxiety disorders.MethodsFrom outpatients program, we consecutively recruited a group of 46 males: 28 patients had major depression and 18 anxiety disorders. Then, we administered two self-report psychometric tools to assess male sexuality, depression and anxiety, i.e., international index of erectile function (IIEF-15), and Depression Anxiety Stress Scales (DASS-21). t-tests and Pearson correlations were performed.ResultsWe found significantly higher score in terms of desire and general sexual wellness in people with anxiety disorder compared to people with depression. However, we found more significant correlations among depressive/anxious symptomatology and sexual impairment in males with anxiety disorders compared to males with depression.ConclusionsOur results revealed that males diagnosed with depression show a decrease of sexual desire, as a vast part of literature previously affirmed. On the contrary, the relationship between psychological symptomatology and sexual dysfunction, as the reduction of erectile function, was higher in males with anxiety disorders. This difference is probably due to a major iatrogenic effect of antidepressive treatments in depressed patients, while in anxious patients could be the psychological state, per se, the main cause of sexual dysfunctions.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
PURPOSE The aim of this study was to investigate homophobic attitudes in three European countries: Italy, Albania, and Ukraine. One thousand and forty-eight students were recruited in Italian (n = 766), Albanian (n = 180), and Ukrainian (n = 102) university centers. METHODS A socio-demographic questionnaire and Homophobia Scale (HS) were administered by our staff. RESULTS Cross-cultural and significant differences among Italian, Albanian, and Ukrainian students were found on the Homophobia Scale (HS; Italy: mean = 22.26 ± 16.73; Albania: mean = 38.15 ± 17.28; Ukraine: mean = 59.18 ± 16.23). The analysis of socio-demographic characteristics revealed that the male gender emerged as main predictor of homophobic attitude in all the three countries, although also a conservative political orientation and the religious belief predict higher homophobia levels in Italy and Albania, particularly. CONCLUSIONS This study revealed that in these European countries assessed, attitudes toward homosexuality are different. Ukrainians display higher levels of homophobia than Albanians and Italians, confirming the central role of cultural differences in homophobic attitudes. Nevertheless, some socio-demographic aspects such as identification as male have a similar influence on homophobic attitudes in all assessed populations.

Abstract
Experiencing an adverse childhood and parental neglect is a risk factor for depression in the adult population. Patients with a history of traumatic childhood develop a subtype of depression that is characterized by earlier onset, poor treatment response and more severe symptoms. The long-lasting molecular mechanisms that are engaged during early traumatic events and determine the risk for depression are poorly understood. In this study, we altered adult depression-like behavior in mice by applying juvenile isolation stress. We found that this behavioral phenotype was associated with a reduction in the levels of the deacetylase sirtuin1 (SIRT1) in the brain and in peripheral blood mononuclear cells. Notably, peripheral blood mRNA expression of SIRT1 predicted the extent of behavioral despair only when depression-like behavior was induced by juvenile--but not adult--stress, implicating SIRT1 in the regulation of adult behavior at early ages. Consistent with this hypothesis, pharmacological modulation of SIRT1 during juvenile age altered the depression-like behavior in naive mice. We also performed a pilot study in humans, in which the blood levels of SIRT1 correlated significantly with the severity of symptoms in major depression patients, especially in those who received less parental care during childhood. On the basis of these novel findings, we propose the involvement of SIRT1 in the long-term consequences of adverse childhood experiences.

Abstract
Abnormal brain connectivity has recently been reported in obsessive compulsive disorder (OCD). However, structural differences in the corpus callosum (CC), the primary structure connecting the two hemispheres, have not been extensively studied. In this case-control study, we recruited 30 patients with OCD and 30 healthy control subjects carefully matched for age, sex and handedness. Combining surface-based mesh-modeling and voxel-based morphometry (VBM), we compared callosal thickness and white matter (WM) density in patients and controls. We investigated associations between callosal structure and cortical gray matter (GM) density, and we related CC measures to neuropsychological performance in OCD. OCD patients showed small anterior and posterior callosal regions compared to healthy control subjects. In the OCD group, anterior callosal thickness was positively correlated with GM density of the right mid-dorso-lateral prefrontal (BA 9/46) area, while posterior callosal thickness was positively correlated with GM density in the left supramarginal gyrus (BA 40). Moreover, posterior callosal WM density was positively correlated with verbal memory, visuo-spatial memory, verbal fluency, and visuo-spatial reasoning performances. Callosal attributes were related to GM density in cortical areas innervated by the CC, and were also related to performance in cognitive domains impaired in the disorder. The CC may therefore be integrally involved in OCD.

Abstract
Seeking biomarkers reflecting disease development in cystic echinococcosis (CE), we used a proteomic approach linked to immunological characterisation for the identification of respective antigens. Two-dimensional gel electrophoresis (2-DE) of sheep hydatid fluid, followed by immunoblot analysis (IB) with sera from patients with distinct phases of disease, enabled us to identify by mass spectrometry heat shock protein 20 (HSP20) as a potential marker of active CE. Using IB, antibodies specific to the 34 kDa band of HSP20 were detected in sera from 61/95 (64%) patients with CE, but not in sera from healthy subjects. IB revealed anti-HSP20 antibodies in a higher percentage of sera from patients with active disease than in sera from patients with inactive disease (81 vs. 24%; P = 10(-4)). These primary results were confirmed in a long-term follow-up study after pharmacological and surgical treatment. Herewith anti-HSP20 antibody levels significantly decreased over the course of treatment in sera from patients with cured disease, relative to sera from patients with progressive disease (P = 0·017). Thus, during CE, a comprehensive strategy of proteomic identification combined with immunological validation represents a promising approach for the identification of biomarkers useful for the prognostic assessment of treatment of CE patients.

Abstract
Infectious and autoimmune pathogenic hypotheses of schizophrenia have been proposed, prompting searches for antibodies against viruses or brain structures, and for altered levels of immunoglobulins. Previous experiments have shown that allele frequencies of the Ig heavy chain 3' enhancer HS1,2*A are associated with several autoimmune diseases, suggesting a possible correlation between HS1,2 alleles and Ig production. To test this, we analyzed levels of serum Igs and HS1,2*A genotypes in two independent cohorts, one of 88 schizophrenic inpatients (24 women) and a second of 133 healthy subjects (59 women). Both groups were similar in the frequency of individuals with altered serum concentration of Ig classes and IgG subclasses (schizophrenia panel-80 percent; controls-68 percent). With the possible exception of a stabilizing effect of olanzapine, no psychopharmacological drug consumed during the month prior to serum sampling in the schizophrenia group significantly affected Ig levels. In both patient and control cohorts, an increased frequency of the HS1,2*2A allele corresponded to increased Ig plasma levels, while an increased frequency of the HS1,2*1A allele corresponded to decreased Ig plasma levels. EMSA analysis with nuclear extracts from human B cells showed that the transcription factor SP1 bound to the polymorphic region of both HS1,2*1A and HS1,2*2A while NF-kB bound only to the HS1,2*2A. We predict that differences in transcription factor binding sites in the two allelic variants of the 3' IgH enhancer HS1,2 may provide a mechanism by which differences in Ig expression are affected.

Abstract
Objective:To explore tolerability, safety and treatment response of flexible doses of oral paliperidone ER in patients with schizophrenia suffering from an acute episode.Methods:Interim analysis of a 6-week prospective, open-label, international study. Endpoints were the rate of responders defined as a ≥30% improvement in the Positive and Negative Syndrome Scale (PANSS) from baseline to endpoint, the Clinical Global Impression-Severity Scale (CGI-S), weight change and adverse events (AEs).Results:100 patients were analyzed (51% male, mean age 39.0±11.6 years). 82% of patients completed the study. Most frequent reasons for early discontinuation were subject choice (10%) and lack of efficacy (7%). the mean dose of paliperidone ER was 5.9 mg/day at baseline and 7.9 mg/day at endpoint. an improvement of ≥30% in total PANSS was observed in 68% of patients (95% confidence interval [CI]58%;77%], with a decrease in mean total PANSS scores from 98.2±16.2 at baseline to 71.1±20.3 at endpoint (mean change -27.1±19.9; 95%CI -31.1;-23.2, p< 0.0001) and onset of efficacy as of day 2. the percentage of patients rated as at least markedly ill in CGI-S decreased from 69% to 20.3%. AEs reported in ≥5% were insomnia (14%), tachycardia (10%), akathisia (6%), extrapyramidal disorder (6%), headache (5%) and schizophrenia (5%). Median weight gain was 0.7 kg (95% CI 0.19;1.96) from baseline to endpoint.Conclusion:This analysis supports data from recent controlled studies that flexibly dosed paliperidone ER is safe, well tolerated and associated with a clinically meaningful treatment response in patients with an acute schizophrenic episode.

Abstract
Early non-invasive diagnostic information would be useful in identifying patients at risk of progressive carotid atherosclerosis, despite an apparently harmless plaque on ultrasound imaging. In this study, we assessed the possible association of intracellular cytokines in peripheral blood with the ultrasound (stenosis > or = 70%) and clinical indications (transient ischaemic attack, amaurosis fugax or stroke) for carotid endarterectomy (CEA) in patients. Intracellular cytokine expression was determined in 106 patients (67 undergoing and 39 not undergoing CEA). Cells primed for the proinflammatory cytokines tumour necrosis factor (TNF)-alpha, interferon (IFN)-gamma, interleukin (IL)-1beta, IL-6, IL-8 and the anti-inflammatory cytokines IL-4 and IL-10 were found in significantly higher percentages in patients undergoing CEA than in patients who were not (P < 0.05). Intracellular cytokine expression was significantly higher in patients undergoing CEA who had stenosis > or = 70% (TNF-alpha, IFN-gamma, IL-1beta, IL-6, IL-4 and IL-10), with previous stroke (IFN-gamma, IL-1beta, IL-6, IL-8, IL-4 and IL-10) and with amaurosis fugax (IFN-gamma, IL-6, IL-4 and IL-10) than in patients not undergoing CEA. Increased intracellular cytokines in patients' peripheral blood might be a warning signal indicating progressive atherosclerosis. If so, intracellular cytokine monitoring could help in selecting patients at high risk of future clinical cardiovascular events and therefore most likely to benefit from CEA or adjustment of pharmacological therapy.

Abstract
Homozygosis for wolframin (WFS1) mutations determines Wolfram syndrome (WS), and common polymorphisms of WFS1 are associated with psychiatric illnesses and dependence behaviour. To test the influence of WFS1 polymorphisms on medication overuse headache (MOH), a chronic headache condition related to symptomatic drugs overuse, we analyzed 82 MOH patients for the WFS1 His611Arg polymorphism, and performed a comparison between clinical features of Arg/Arg (R/R) and non-R/R individuals. Individuals harbouring the R/R genotype showed significantly higher monthly drug consumption (t=-3.504; p=0.00075) and more severe depressive symptoms on the BDI questionnaire (t=-3.048; p=0.003) than non-R/R. WFS1 polymorphism emerged as the only significant predictor of drug consumption, at the multivariate regression analysis (F=12.277; d.f.=1,80; p=0.00075, adjusted R2=0.122). These results implicate WFS1 in the clinical picture of MOH, may be through an influence on need for drugs as in other conditions of abuse behaviour.

Abstract
This study discusses the epidemiology and immunodiagnosis of cystic echinococcosis (caused by Echinococcus granulosus). Despite the development of molecular methods to prepare antigens, nowadays there is no standard, highly sensitive, and specific test available for antibody detection in cystic echinococcosis. Furthermore, because serological tests can give only a limited support to clinical findings there is a clear need for new advances in immunodiagnosis of E. granulosus infection.

Abstract
The worldwide problem of chronic Echinococcus granulosus disease calls for new parasite-derived immunomodulatory molecules. By screening an E. granulosus cDNA library with IgG4 from patients with active cystic echinococcosis, we identified a cDNA that encodes a predicted partial protein that immunofluorescence studies localized in the protoscolex tegument and on the germinal layer of cyst wall. We named this protein EgTeg because the 105 amino acid sequence scored highest against a family of Schistosoma tegumental proteins. Evaluating the role of EgTeg in the human early inflammatory response we found that EgTeg significantly inhibited polymorphonuclear cell (PMN) chemotaxis. Cytometric analysis of intracellular cytokines disclosed a significantly higher percentage of cells producing IL-4 than IFN-gamma (P = 0.001, Student's t-test) in T lymphocytes from patients with cystic echinococcosis stimulated with EgTeg. EgTeg induced weak Th1-dependent proliferation in 42% of patients' peripheral blood mononuclear cells. In immunoblotting (IB) analysis of total IgG and IgG subclass responses to EgTeg in patients with cystic echinococcosis, patients with other parasitoses, patients with cystic lesions and healthy controls, total IgG specific to EgTeg yielded high sensitivity (73%) but low specificity (44%) precluding its use in immunodiagnosis. Conversely, IgG4 specific to EgTeg gave acceptable sensitivity (65%) and high specificity (89%) suggesting its use in immunodiagnosis to confirm ultrasound documented cysts suggestive of E. granulosus. Because the new tegumental antigen EgTeg inhibits chemotaxis, induces IL-4-positive T lymphocytes and noncomplement fixing antibodies (IgG4) it is an immunomodulatory molecule associated with chronic infection.

Abstract
Far from disproving the model of mind functioning proposed by psychoanalysis, the recent advances in neuropsychiatrical research confirmed the crucial ideas of Sigmund Freud. The hypothesis that the origin of mental illnesses lies in the impossibility for a subject to erase the long-term effects of a remote adverse event is in tune with the view that several psychiatric disturbances reflect the activation of aberrant unconscious memory processes. Freud's insights did not stop here, but went on to describe in an extremely precise manner the neural mechanisms of memory formation almost a century before the description of long-term synaptic potentiation.

Abstract
This study discusses the immunodiagnosis of cystic echinococcosis (ce, caused by Echinococcus granulosus). The detection by immunoblotting of antibodies specific for the 8 kDa subunit of antigen B and in particular the IgG4 subclass expression, seems the most promising serodiagnostic tool. Despite the development of molecular methods, nowadays there is no standard, highly sensitive, and specific test available for antibody detection in CE. Furthermore, because serological tests can give only a limited support to clinical findings there is a clear need for new advances in immunodiagnosis of E. granulosus infection.

Abstract
To investigate the role of T lymphocytes in the immune response to Echinococcus granulosus, using sheep hydatid fluid (SHF) and antigen B (AgB), we generated T-cell lines from patients with active, transitional and inactive hydatid cysts. We established 16 T-cell lines, eight specific to SHF and eight specific to AgB. At surface phenotyping 88-98% of cells displayed the helper/inducer CD4 antigen. In all patients, at all clinical stages of hydatid cyst disease, T-cell stimulation with SHF and AgB invariably amplified a large number of almost identical Vbeta subfamily fragments. Irrespective of antigen-specificity, the two cell lines from the patient with an inactive cyst had a Th1 profile, because they exclusively expressed and produced IFN-gamma. Conversely, the T-cell lines derived from the seven patients with active and transitional hydatid cysts had mixed Th1/Th2 and Th0 clones. The functional characteristics of the 16 T-cell lines differed markedly in the various clinical stages of cystic echinococcosis, thus providing new in vitro evidence that Th1 lymphocytes contribute decisively to the inactive stage of hydatid disease, Th2 lymphocytes in the active and transitional stages. The parasite-specific T-cell lines, especially the two Th1 lines from the patient with an inactive cyst, may help identify Th1 protective epitopes on SHF and AgB.

Abstract
The humoral immune response to endothelium has a pivotal role in the development of atherosclerosis. Using a molecular method, we sought to identify endothelial autoantigens in carotid atherosclerosis. Immunoscreening of a HUAEC expression library with IgG from a pool of two sera from patients with carotid atherosclerosis identified a clone specific to actin. We evaluated actin-specific IgG reactivity in patients with carotid atherosclerosis and compared responses with those in patients with systemic lupus erythematosus and type 1 diabetes mellitus and in healthy subjects. Enzyme-linked immunoassay detected actin-specific IgG in a significantly higher percentage of sera from patients with atherosclerosis and systemic lupus erythematosus than from healthy subjects (16/61, 26% and 13/33, 39%versus 2/41, 5%, P = 0.012 and P < 10(-4), by chi2 test). Mean optical density values were significantly higher in patients than in healthy subjects (P < 10(-4) by Student's t-test). Patients with atherosclerosis and uncomplicated plaques had significantly higher serum anti-actin IgG reactivity than those with complicated plaques (P = 0.048 by Student's t-test). Our findings suggest that actin is an autoantigenic molecule of potential clinical interest in carotid atherosclerosis.

Abstract
AIM We investigated a possible relationship of cytokine expression and phenotype features of circulating T lymphocytes with the histological type of atherosclerotic plaque removed during carotid endarterectomy. METHODS Peripheral blood samples were taken from 20 patients with carotid atherosclerosis and from 8 healthy blood donors. Patients were divided into 2 groups according to the histological type of their atherosclerotic plaques (types V and VI). Expression of intracellular tumor necrosis factor (TNF)-alpha, interferon (IFN)-gamma, interleukin-4 (IL-4), and of surface antigens (CD4, CD8, CD45RA, CD45RO, T cell receptor (TCR) alpha/beta, TCR gamma/delta) in circulating T lymphocytes was determined by 3-colour cytofluorimetric analysis. RESULTS The percentage of T lymphocytes primed for TNF-alpha, IFN-gamma and IL-4 was higher in blood samples from patients than from healthy subjects; the difference was statistically significant for TNF-alpha-producing cells (p=0.01). In patients, the percentage of TNF-alpha-producing cells was significantly higher in the CD4+ subset than in the CD8+ subset (p=10(-4)). The percentage of TNF-alpha-, IFN-gamma- and IL-4-primed cells was higher in patients with type VI plaques (complicated lesions) than in patients with type V plaques (less complicated lesions). The difference was statistically significant for TNF-alpha-primed cells (p=0.05). No statistically significant differences were found in T cell phenotype features among patients or between patients and healthy subjects. CONCLUSION Our results suggest a relationship between the percentage of circulating T lymphocytes expressing TNF-alpha and possibly IFN-gamma and IL-4 and the histological type of atherosclerotic plaque in patients with carotid artery disease.

Abstract
By screening an expression library of Echinococcus granulosus with IgE from sera of patients with cystic echinococcosis (CE) and allergic reactions, we isolated the C-terminal region of a new heat shock protein (HSP)70 of E. granulosus. The protein, named Eg2HSP70, has close homology with the C-terminal region of Dermatophagoides farinae and human HSP70. We investigated the humoral and cell-mediated immune responses to this antigen in patients with CE grouped according to the presence of allergic reactions. Immunoblotting detected total IgG, IgG4 and IgE specific to Eg2HSP70 (83% of sera contained IgG, 31% IgG4 and 57% IgE). No significant difference was found in immunoglobulin percentages according to the presence of allergic reactions. Immunoblotting inhibition showed that no IgG or IgE specific to Eg2HSP70 cross-reacted with D. farinae or human HSP70. Eg2HSP70-stimulated PBMC from 26 patients produced significantly greater amounts of TNF-alpha, IFN-gamma, and IL-10 than unstimulated cultures in all patients, irrespective of the presence of allergic reactions (P < 0.05). They also produced significantly greater amounts of IL-4 than unstimulated cultures exclusively in patients with allergic reactions (P < 0.05). These findings show that Eg2HSP70 is a new antigenic molecule inducing both B and T cell responses.

Abstract
The latest developments in the molecular and cellular mechanisms that underlie Echinococcus infection have renewed interest in the immunodiagnosis of this disease and have helped in understanding the host-parasite relationship. This review discusses current concepts on the immune response to Echinococcus granulosus in humans, and relates these findings to diagnosis and clinical management. The two most promising molecular tools developed for the immunodiagnosis of cystic echinococcosis involve isolating native or recombinant parasite antigens to detect specific serum antibodies in patients with suspected echinococcosis and producing monoclonal antibodies to detect parasite antigens in clinical samples. Novel drugs should be designed to strengthen host immune responses thus combating parasitic survival. Currently, attention has been focused on understanding T-helper lymphocyte activity; in particular the role of Th1 and Th2 subsets in orchestrating immune responses. The Th1/Th2 model explaining how selective immune responses--including cell-mediated or humoral immunity--develop, seems promising as the rationale for molecular tools that could lead to new therapeutic strategies.

Abstract
Seeking better immunological markers indicating the long-term outcome of cystic echinococcosis (CE) after chemotherapy we studied 23 patients receiving albendazole, clinically followed for 8 years, and grouped ultrasonographically according to therapeutic outcome. Antibody responses against a partially purified fraction of hydatid fluid (HFF) and antigen B (AgB) were evaluated by indirect haemagglutination (IHA), ELISA and immunoblotting (IB). Although IHA titres varied over the course of treatment, differences in mean antibody titres to HFF between groups were significant only at 4 years (P = 0.031). IgG isotype expression remained unchanged during follow-up whereas IgE expression decreased in patients with cured or stable disease. AgB disclosed higher IgG4 expression (P < 10(-4); P = 0.025) and lower IgG1 expression than HFF (P < 10(-4); P = 0.022). IHA antibody titres were higher in patients with progressive than in those with cured or stable disease, even in those with the same cyst type. ELISA isotype profiles differed between groups, particularly for type CE 3, 4 and 5 cysts: higher serum IgG1 and IgG3, lower IgG4 and IgE in patients with cured or stable disease. Although combined serological testing provides scarce information on the long-term outcome of CE after chemotherapy it may be useful for reviewing in a retrospective study the outcome of a cyst and for assessing the host-parasite relationship.

Abstract
By immunological screening of a cDNA library derived from protoscoleces of Echinococcus granulosus with IgE from patients with cystic echinococcosis (CE) and allergic manifestations, we isolated a protein identical to E. granulosus cyclophilin. The protein, named EA21, has close homology with Malassezia furfur cyclophilin allergen (Mal f 6) and with human cyclophilin. Using immunoblotting (IB) with a polyclonal antibody specific to EA21, we identified E. granulosus cyclophilin both in protoscoleces and in sheep hydatid fluid. Of the 58 sera from patients with CE, 29 (50%) were IgE positive to EA21, whereas, despite the high sequence homology, none were IgE positive to Mal f 6 or human cyclophilin. Only 26 of the 58 patients (45%) had IgG specific to EA21, whereas all patients (100%) had IgG specific to Mal f 6 and human cyclophilin. IB analysis showed that serum IgE-binding reactivity to EA21 differed significantly in patients with and without allergic reactions (20 of 25, 80% versus nine of 33, 27%; P < 10(-4)). Conversely, five of the 25 patients who had CE-related allergic manifestations (20%) and 21 of the 33 who did not (63%) had specific IgG4 (P = 10(-3)) and total IgG to EA21. EA21 induced a proliferative response in 15 of 19 (79%) patients' PBMC regardless of the allergic manifestations, but it induced no IL-4 production. Overall, these findings suggest that E. granulosus cyclophilin is a conserved, constitutive, parasite protein that does not cross-react with cyclophilins from other organisms and is involved in the allergic symptoms related to CE.

Abstract
The purpose of this study was to determine whether dihydropteroate synthase gene (DHPS) mutations were associated with the failure of sulpha/sulphone drugs used as prophylaxis agents in HIV infected patients. Results suggested that DHPS mutations were significantly associated with failure of anti-Pneumocystis carinii sulphone prophylaxis (P=0.031). An increasing number of mutant P. carinii strains have been isolated from patients no longer having prophylaxis. There was no statistically significant difference in severity or outcome of the pneumonia caused by wild-type or mutant DHPS. Moreover, two of the three patients with mutant P. carinii pneumonia (PCP) were successfully treated with sulpha drugs. We think that P. carinii drug-resistance could be an emerging problem for immunocompromised patients including those with HIV infection.

Abstract
Allergic reactions, such as urticaria, itching and anaphylactic shock, often complicate the course of cystic echinococcosis (CE). To investigate the role of the IgE-immunoreactive recombinant Echinococcus granulosus elongation factor-1 beta/delta (EgEF-1 beta/delta) in the allergic disorders during CE we determined humoral and cell-mediated responses to this antigen in patients with CE grouped according to the clinical presence or absence of allergic reactions. Immunoblotting analysis showed that serum IgE-binding reactivity to EgEF-1 beta/delta differed significantly in patients with and without allergic reactions (38 of 42, 90% vs. 31 of 56, 56%; P < 10(-4)). EgEF-1 beta/delta induced a proliferative response in 14 of 19 (74%) patients' peripheral blood mononuclear cells (PBMC) irrespective of the allergic manifestations and skewed Th1/Th2 cytokine activation towards a preferentially Th2 polarization. Epitope mapping identified an immunodominant epitope of 18 residues with 78% identity and 89% similarity with an IgE-immunoreactive Strongyloides stercoralis antigen. Overall these findings suggest that EgEF-1 beta/delta is an allergenic molecule that may be a general marker of the intensity of CE immune response and that could lead to a deeper understanding of the specific antigen-induced mechanisms underlying allergic reactions in the human host.

Abstract
By directly suppressing the function of certain immune cell subsets and by stimulating other cell populations related to immunopathology, parasite-derived substances play an important role in the chronic establishment of parasitic disease. Our objective was twofold: (i) to investigate further the role of Echinococcus granulosus antigen B (AgB) in the human early inflammatory response by determining its effect on polymorphonuclear cell (PMN) random migration, chemotaxis, and oxidative metabolism and (ii) to determine its action in acquired immunity by evaluating AgB and sheep hydatid fluid (SHF)-driven Th1 (gamma interferon [IFN-gamma] and interleukin 12 [IL-12]) and Th2 (IL-4 and IL-13) cytokine production by peripheral blood mononuclear cells (PBMC) from 40 patients who had cured or stable or progressive cystic echinococcosis. AgB significantly inhibited PMN recruitment but left their random migration and oxidative metabolism unchanged. Patients' PBMC stimulated with AgB produced IL-4 and IL-13 but did not produce IL-12. They also produced significantly lower IFN-gamma concentrations than did PBMC stimulated with SHF (P = 10(-5)). AgB skewed the Th1/Th2 cytokine ratios towards a preferentially immunopathology-associated Th2 polarization, predominantly in patients with progressive disease. AgB-stimulated patients' PBMC also proliferated less than SHF-stimulated PBMC (P = 9 x 10(-3)). In vitro Th2 cytokine production was reflected in vivo by elevated specific immunoglobulin E (IgE) and IgG4 antibodies binding to AgB. These findings confirm that AgB plays a role in the escape from early immunity by inhibiting PMN chemotaxis. They also add new information on the host-parasite relationship, suggesting that AgB exploits the activation of T helper cells by eliciting a nonprotective Th2 cell response.

Abstract
To evaluate the diagnostic sensitivity and specificity of immunoelectrophoresis (IEP), indirect haemagglutination (IHA), enzyme-linked immunosorbent assay (ELISA) and immunoblotting (IB), we compared their ability in detecting IgG antibodies to a hydatid fluid fraction (HFF) and to native and recombinant antigen B of Echinococcus granulosus. We tested sera from patients who had cystic echinococcosis (CE) grouped according to their type of cysts (n = 204), from patients with other parasitic diseases (n = 21), lung or liver carcinomas (n = 6) or serous cysts (n = 26) and from healthy controls (n = 90). HFF-IB gave the highest sensitivity (80%) followed by ELISA (72%), IHA (54%) and IEP (31%), respectively. The diagnostic sensitivity significantly (P < 0.01) decreased as cysts matured from type I-II to type VII. Recombinant and native antigen B-IB yielded similar sensitivity (74%). A large number of clinically or surgically confirmed CE patients (20%) resulted negative. In these patients' sera, IB to assess the usefulness of the recombinant E. granulosus elongation factor-1 beta/delta in detecting IgE antibodies yielded 33% of positivity. Our findings underline the need to standardize techniques and antigenic preparations and to improve the performance of immunodiagnosis by characterizing new antigens and detecting distinct immunoglobulin classes.

Abstract
The influence of pharmacological treatment on the immune response of patients with Echinococcus granulosus infection was evaluated by reverse transcriptase-polymerase chain reaction (RT-PCR) to determine mRNA expression for IL-12 p35, IL-12 p40, interferon-gamma (IFN-gamma), tumour necrosis factor-alpha (TNF-alpha) and IL-4 in PBMC from 12 patients before and after chemotherapy and from seven uninfected controls. Most patients' PBMC showed measurable amounts of IL-12 p35, IL-4, IFN-gamma and TNF-alpha mRNA in parasite antigen-stimulated and unstimulated cultures. Conversely, IL-12 p40 mRNA was detected almost exclusively in successfully treated patients (86%) after therapy. In these patients semiquantitative analysis of RT-PCR products showed a significant difference between IL-12 p40 mRNA mean levels before and after therapy (P = 0.03 in parasite antigen-stimulated cultures; P = 0.001 in unstimulated cultures). IL-4 mRNA was weakly expressed before therapy and more highly so after treatment in both groups of patients and under both culture conditions; IL-4 mRNA reached its highest level in post-therapy PBMC from patients in whom therapy failed (stimulated cultures). IFN-gamma and TNF-alpha mRNA expression increased in patients who responded to therapy and decreased in patients who did not. In contrast to IL-12 p35, IFN-gamma and TNF-alpha mRNAs, IL-12 p40 and IL-4 mRNAs were detected exclusively in patients, suggesting a close relationship between these two cytokines and cystic echinococcosis. Our findings indicate that chemotherapy influences the immune response, thus determining changes in Th1/Th2 cytokine mRNA patterns, predominantly in IL-12 p40 and IL-4 mRNA expression.
