Background: Over-standard methadone doses are generally needed in the treatment of heroin use disorder (HUD) patients that display concomitant high-severity psychopathological symptomatology. A flexible dosing regimen may lead to higher retention rates in dual disorder (DD), as we demonstrated in bipolar 1 HUD patients, leading to outcomes that are as satisfactory as those of HUD patients without high-severity psychopathological symptomatology.

Objective: This study aimed to compare the long-term outcomes of treatment-resistant chronic psychosis HUD patients (PSY-HUD) with those of peers without dual disorder (HUD).

Introduction In this study, we used a symptomatology checklist (SCL-90) to substantiate the hypothesis that Substance Use Disorder (SUD) has its own five-dimensional psychopathology. The aim of the present study was to test whether this psychopathology can be differentiated from other psychiatric psychopathological dimensions (such as obesity). The severity and frequency of each of the five dimensions were investigated, at univariate and multivariate levels, by comparing 972 Heroin Use Disorder (HUD) patients (83.

Addiction is a mental illness in which psychiatric conditions imply a prominent burden. Psychopathological symptoms in substance use disorder (SUD) patients are usually viewed as being assignable to the sphere of a personality trait or of comorbidity, leaving doubts about the presence of a specific psychopathology that could only be related to the toxicomanic process. Our research group at the University of Pisa has shed light on the possible definition of a specific psychopathological dimension in SUDs.

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.

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.

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.

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.

Objectives: The presence of aggressive and self-harm behaviors is common in heroin-addicted patients, but these frequent co-occurrences have been poorly investigated. Given the fact that self-harm may be seen as both a clear addictive behavior, with its opiate theory, and as part of psychiatric illness, such as psychosis and bipolar spectrum disorders, in this study, we intend to investigate which of the 2 models is more consistent.

Methods: We compared dual diagnosis with the clinical features of 30 moderate/superficial self-harmed and 162 violent heroin-addicted patients who reported aggressive behavior in the month preceding their request to be treated.

Background: Psychoses correlated with substance abuse prove to be more common in cases involving cannabinoids, stimulants, hallucinogens, alcohol and polyabuse. Among substance abusers, it has not been ascertained whether opioids have a psychotic effect.

Objectives: The aim of this review is to investigate whether, among substances of abuse, a distinction can be drawn between pro-psychotic and anti-psychotic agents on the basis of the relationship between these substances and psychosis.

Article Synopsis
  • The study aimed to compare the long-term treatment outcomes of bipolar 1 heroin addicts versus heroin addicts without psychiatric comorbidities.
  • Over 3 years, patients receiving Methadone Maintenance Treatment were monitored, revealing that bipolar 1 patients had slightly better treatment retention and overall outcomes despite needing higher methadone doses.
  • Limitations included the inability to track dropouts and the influence of individual differences on treatment effectiveness, leading to unexpected results where bipolar 1 patients fared better than those without additional psychiatric issues.

Background: Kraepelin and Kretschmer hypothesized a continuum between full-blown affective pathology and premorbid temperaments. More recently Akiskal proposed a putative adaptive role for the four fundamental temperaments: the hyperthymic one characterized by emotional intensity, the cyclothymic one by emotional instability, the depressive one by a low energy level, and the irritable one by an excessive response to stimuli. Today it is widely debated whether affective temperaments belong to the domain of pathology or to that of normality.

Background: Consistently with the involvement of affective temperaments in professional choices, our research team is aiming to outline the temperamental profile of subjects who are applying to enter a military career in the Italian Armed Forces. In this study we aim to verify the importance of temperamental traits not only in choosing the military career as a profession, but also in passing or failing the entrance examinations.

Methods: We compared the affective temperaments (evaluated by TEMPS-A[P]) of those applying to become a cadet officer in the Italian Navy, divided into various subgroups depending on whether they passed or failed the entrance examination at various levels (high school final test, medical (physical and psychiatric), mathematical examination and aptitude test).

Negative symptoms, conceptualized as clinical manifestations of schizophrenia, and subsequently described in other psychiatric disorders, include the loss of normal arousal, drive and affective reactivity. In the field of substance abuse, an interesting analogy can be detected between negative symptoms, in their classical meaning, and the amotivational syndrome (AS), which has been described as a form of chronic cannabis intoxication. AS also shows a close resemblance to the reward deficiency syndrome (RDS) of alcoholics and stimulant abusers, and to the post-withdrawal syndrome (PWS) of detoxified heroin addicts.

Nowadays, the misuse of benzodiazepines (BZDs) is a cause for a serious concern among pharmacologically inexperienced patients, whether treated or untreated, that could lead to significant complications, including tolerance, dependence, and addiction. We present a case report in which an Italian patient affected by anxiety disorder and treated with BZDs presented a severe case of dependence on BZDs. We treated him according to an agonist substitution approach, switching from the abused BZD to a slow-onset, long-acting, high potency agonist (clonazepam), and looking at the methadone treatment model as paradigm.

Background: Studies on the 'self-medication hypothesis' have focused on substance abuse as an attempt to alleviate emotional suffering.

Methods: We have investigated concomitant substances of abuse in 150 bipolar heroin addicts clustered according to their clinical presentation at treatment entry (depressive episode, hypomanic episode, manic episode and mixed episode). Bipolar heroin addicted patients were chosen because they tend to have a concomitant poly-substance abuse and because, as compared with patients suffering for other mental illnesses, they more clearly reveal a variety of identifiable affective states.

Background: The Temperament Evaluation of the Memphis, Pisa, Paris and San Diego Questionnaire (TEMPS) has, in its self and rater-wise evaluation form, been designed to evaluate temperamental characteristics in clinical and non-clinical populations.

Methods: In this study we aim to extend the field of correlations of TEMPS to include the Occupational Personality Questionnaire, ipsative version (OPQ32i). These correlations, if present, could provide a partial contribute to the validation process of TEMPS, currently in progress in various countries.

Background: Temperament appears to be a factor involved in professional attitudes. The most impressive findings are those on the importance of cyclothymia in art and of hyperthymia in leadership.

Aim: In this study we raise the issue of whether the relationship between hyperthymic temperament and the choice of a military career, previously reported among Italian Air Force applicants, can be extended to another military service such as the Italian Navy.

Background: Ecstasy use is generally chosen by adolescents and young adults for its entactogenic properties (the production of feelings of empathy, love, and emotional closeness to others.) Despite this desired and frequently realized outcome, Ecstasy use has often resulted in the genesis of psychotic symptoms and aggressive behaviors, particularly after chronic and/or intensive use.

Methods: To explore the negative consequences of Ecstasy use and to examine the aggressive nature oftentimes seen in many Ecstasy users we employed a case-control study model.

In a group of 1066 heroin addicts, who were seeking treatment for opioid agonist treatment, we looked for differences in historical, demographic, and clinical characteristics, between patients with different levels of awareness of illness (insight). The results showed that, in the cohort studied, a majority of subjects lacked insight into their heroin-use behavior. Compared with the impaired-insight group, those who possessed insight into their illness showed significantly greater awareness of past social, somatic, and psychopathological impairments, and had a greater number of past treatment-seeking events for heroin addiction.

In this study we evaluated, by means of the "cocaine rush visual analog scale," the impact of ropinirole on the expected rush induced by cocaine in a group of heroin addicts abusing cocaine; the self-reported reaction to the rush blockade (if any) on cocaine consumption, and the correlations between this self-reported reaction and individual, clinical, and therapeutic parameters. Nineteen cocaine abuser heroin-dependent patients entered the study. Their experienced cocaine rush was 61.

Leading Italian studies support the use of γ-hydroxybutyric acid (GHB), not only in the treatment of the alcohol withdrawal syndrome, but also in maintaining alcohol abstinence. GHB gives a better result than naltrexone and disulfiram in maintaining abstinence, and it has a better effect on craving than placebo or disulfiram. The problem is that about 30-40% of alcoholics are non-responders to GHB therapy.

Background: The idea that the impact of opioid agonist treatment is influenced by the psychopathological profile of heroin addicts has not yet been investigated, and is based on the concept of a specific therapeutic action displayed by opioid agents on psychopathological symptoms. In the present report we compared the effects of buprenorphine and methadone on the psychopathological symptoms of 213 patients (106 on buprenorphine and 107 on methadone) in a follow-up study lasting 12 months.

Methods: Drug addiction history was collected by means of the Drug Addiction History Rating Scale (DAH-RS) and psychopathological features were collected by means of the Symptom Checklist-90 (SCL-90), using a special five-factor solution.
