ABSTRACT
BACKGROUND: In the Gambling Disorder (GD), there is no exogenous drug administration that acts as the central core of the traditional meaning of addiction. A specific psychopathology of Substance Use Disorders has been proposed recently. In a sample of Heroin Use Disorder (HUD) patients entering opioid agonist treatment, it became possible to identify a group of 5 mutually exclusive psychiatric dimensions: Worthlessness-Being trapped (W-BT), Somatic Symptoms (SS), Sensitivity-Psychoticism (SP), Panic Anxiety (PA) and Violence-Suicide (VS). The specificity of these dimensions was suggested by the absence of their correlations with treatment choice, active substance use, psychiatric comorbidity and the principal substance of abuse and by the opportunity, through their use, of fully discriminating HUD from Major Depression patients and, partially, from obese non-psychiatric patients. To further support this specificity in the present study, we tested the feasibility of discriminating HUD patients from those affected by a non-substance-related addictive behaviour, such as GD. In this way, we also investigated the psychopathological peculiarities of GD patients. METHODS: We compared the severity and frequency of each of the five aspects found by us, in 972 (83.5% males; mean age 30.12 ± 6.6) HUD and 110 (50% males; average age 30.12 ± 6.6) GD patients at univariate (T test; Chi square) and multivariate (discriminant analysis and logistic regression) level. RESULTS: HUD patients showed higher general psychopathology indexes than GD patients. The severity of all five psychopathological dimensions was significantly greater in HUD patients. Discriminant analysis revealed that SS and VS severity were able to discriminate between HUD (higher severity) and GD patients (lower severity), whereas PA and SP could not. W-BT severity was negatively correlated with SS and VS; GD patients were distinguished by low scores for SS and VS low scores associated with high ones for W-BT. Psychopathological subtypes characterized by SS and VS symptomatology were better represented in HUD patients, whereas PA symptomatology was more frequent in GD individuals. No differences were observed regarding the W-BT and SP dimensions. At multivariate level, the one prominent characteristic of HUD patients was the presence of SS (OR = 5.43) as a prominent qualification for psychopathological status. CONCLUSIONS: Apart from the lower severity of all psychopathological dimensions, only the lower frequency of SS typology seems to be the prominent factor in GD patients. The SCL90-defined structure of opioid addiction seems to be useful even in non-substance-related addictive disorders, as in the case of GD patients, further supporting the possible existence of a psychopathology specific to addiction.
ABSTRACT
INTRODUCTION: In the last decade, the comprehension of affective temperaments has helped us to outline the boundaries of mood disorders, and to expand our knowledge of nosographic areas other than those of affectivity, even if affectivity is closely related to them. In the field of substance use disorders, the temperamental profile of heroin addicts and alcoholics has been discussed elsewhere, but no comparison has yet been made between these two patient populations. Such a comparison would help to shed light on the pathogenetic mechanisms that link temperament with substance abuse. METHODS: 63 Heroin Use Disorder (HUD) and 94 Alcohol Use Disorder (AUD) patients were compared with 130 healthy controls, with the aim of outlining affective temperament quantity and typology according to the formulation of Akiskal and Mallya. RESULTS: Cyclothymic temperamental quantity differentiated - both at the univariate and multivariate levels - between patients who had various different types of Substance Use Disorder, largely irrespective of the principal substance of abuse (heroin or alcohol); irritable temperament quantity differentiated HUD patients from AUD patients. Hyperthymic temperament typology seemed to be more frequent in healthy controls at both univariate and multivariate levels. LIMITATION: Cross-sectional study. CONCLUSIONS: Our analyses suggest that cyclothymic temperament quantity could best correspond to the temperamental profile of Substance Use Disorder patients independently of principal substance of abuse (alcohol or heroin), and that irritable temperament quantity may differentiate HUD from AUD patients. Hyperthymic temperament typology seemed to be highly protective for HUD and, though a bit less, for AUD patients, and was a typical feature of healthy controls.

BACKGROUND: Recent celebrity deaths have been widely reported in the media and turned the public attention to the coexistence of mood, psychiatric and substance-abuse disorders. These tragic and untimely deaths motivated us to examine the scientific and clinical data, including our own work in this area. The self-medication hypothesis states that individuals with psychiatric illness tend to use heroin to alleviate their symptoms. This study examined the correlations between heroin use, mood and psychiatric disorders, and their chronology in the context of dual diagnosis. METHODS: Out of 506 dual diagnosed heroin addicts, 362 patients were implicated in heroin abuse with an onset of at least one year prior to the associated mental disorder (HER-PR), and 144 patients were diagnosed of mental illness at least one year prior to the associated onset of heroin use disorder (MI-PR). The retrospective cross-sectional analysis of the two groups compared their demographic, clinical and diagnostic characteristics at univariate and multivariate levels. RESULTS: Dual diagnosis heroin addicts whose heroin dependences existed one year prior to their diagnoses (HER-PR) reported more frequent somatic comorbidity (p≤0.001), less major problems at work (p=0.003), more legal problems (p=0.004) and more failed treatment for their heroin dependence (p<0.001) in the past. More than 2/3 reached the third stage of heroin addiction (p=<0.001). Their length of dependence was longer (p=0.004). HER-PR patients were diagnosed more frequently as affected by mood disorders and less frequently as affected by psychosis (p=0.004). At the multivariate level, HER-PR patients were characterized by having reached stage 3 of heroin dependence (OR=2.45), diagnosis of mood disorder (OR=2.25), unsuccessful treatment (OR=2.07) and low education (OR=1.79). LIMITATIONS: The main limitation is its retrospective nature. Nonetheless, it does shed light on what needs to be done from a clinical and public health perspective and especially prevention. CONCLUSIONS: The data emerging from this study, does not allow us to determine a causal relation between heroin use and mental illness onset. However, this data, even if requiring longitudinal studies, suggest that self-medication theory, in these patients, can be applied only for chronic psychoses, but should not be applied to patients with mood disorders using heroin.

In an effort to inquiry the "self-medication hypothesis" in heroin-dependent patients suffering from chronic psychosis and bipolar disorder, a naturalistic comparative cohort study was designed with the aim of comparing, according to the presence of dual diagnosis, the clinical characteristics of heroin-dependent patients presenting for their first agonist opioid treatment. The main finding was that addictive (heroin) illness was more severe in bipolar 1 patients and less severe in chronic psychotic patients when compared with heroin-dependent patients without dual diagnoses. In the case of chronic psychotic patients, these differences do not allow us to exclude a therapeutic heroin use, at least at the beginning of their toxicomanic career, with limited progression of their addictive disease. This occurrence seems to be excluded for bipolar 1 heroin-dependent patients, who come to their first agonist opioid treatment with a more severe addictive disease.

BACKGROUND: The pursuit for healthy food consumption is considered a laudable habit. This attitude can turn into pathological when cognitions and worries about healthy nutrition lead to such an accurate food selection that correct diet becomes the most important part of one's own life leading to important dietary restrictions, stereotyped eating or impairment in important areas of functioning. This behaviour is coined orthorexia nervosa (ON) and can share common characteristics with anorexia nervosa (AN) and bulimia nervosa (BN). The purpose of the present study was to examine the frequency of ON among women with eating disorders (EDs) and to evaluate if it changed after treating the ED. METHODS: Thirty-two patients with AN or BN were evaluated by means of the ORTO-15, the Yale-Brown-Cornell Eating Disorder Scale (YBC-EDS) and the Eating Attitude Test (EAT-26) before (t0) and 3 years after the treatment of their ED (t1), and compared to 32 female healthy controls (HC) matched by gender, age, and BMI at t1. RESULTS: A significantly higher percentage of patients either at t0 (28 %) or t1 (58 %) resulted positive to ORTO-15 compared to controls (6 %). YBC-EDS and EAT-26 scores were higher among ED patients than in HC, but they decreased from t0 to t1. CONCLUSIONS: Orthorexia nervosa symptoms are highly prevalent among patients with AN and BN, and tend to increase after treatment. ON seems associated both with the clinical improvement of AN and BN and the migration towards less severe forms of EDs. It is necessary to clarify if ON residual symptomatology can be responsible for a greater number of relapses and recurrences of EDs.

BACKGROUND: Glutamate system is modified by ethanol and contributes both to the euphoric and the dysphoric consequences of intoxication, but there is now growing evidence that the glutamatergic system also plays a central role in the neurobiology and treatment of mood disorders, including major depressive disorders and bipolar disorders. We speculate that, using acamprosate, patients with bipolar depression (BIP-A) can take advantage of the anti-glutamate effect of acamprosate to "survive" in treatment longer than peers suffering from non-bipolar depression (NBIP-A) after detoxification. METHOD: We retrospectively evaluated the efficacy of a long-term (six-month) acamprosate treatment, after alcohol detoxification, in 41 patients (19 males and 22 females), who could be classified as depressed alcoholics, while taking into account the presence/absence of bipolarity. RESULTS: During the period of observation most NBIP-A patients relapsed, whereas a majority of BIP-A patients were still in treatment at the end of their period of observation. The cumulative proportion of 'surviving' patients was significantly higher in BIP-A patients, but this finding was not related to gender or to other demographic or clinically investigated characteristics. The treatment time effect was significant in both subgroups. The treatment time-group effect was significant (and significantly better) for bipolar patients on account of changes in the severity of their illness. LIMITATIONS: Retrospective methodology and the lack of DSM criteria in diagnosing bipolarity. CONCLUSIONS: Bipolarity seems to be correlated with the efficacy of acamprosate treatment in inducing patients to refrain from alcohol use after detoxification (while avoiding relapses) in depressed alcoholics. Placebo-controlled clinical trials are now warranted to check the validity of this hypothesis.
