BACKGROUND: Substance use disorders (SUD) often co-occur with attention deficit hyperactivity disorder (ADHD). Although the short-term effects of some specific interventions have been investigated in randomized clinical trials, little is known about the long-term clinical course of treatment-seeking SUD patients with comorbid ADHD. AIMS: This paper presents the protocol and baseline clinical characteristics of the International Naturalistic Cohort Study of ADHD and SUD (INCAS) designed and conducted by the International Collaboration on ADHD and Substance Abuse (ICASA) foundation. The overall aim of INCAS is to investigate the treatment modalities provided to treatment-seeking SUD patients with comorbid ADHD, and to describe the clinical course and identify predictors for treatment outcomes. This ongoing study employs a multicentre observational prospective cohort design. Treatment-seeking adult SUD patients with comorbid ADHD are recruited, at 12 study sites in nine different countries. During the follow-up period of nine months, data is collected through patient files, interviews, and self-rating scales, targeting a broad range of cognitive and clinical symptom domains, at baseline, four weeks, three months and nine months. RESULTS: A clinically representative sample of 578 patients (137 females, 441 males) was enrolled during the recruitment period (June 2017-May 2021). At baseline, the sample had a mean age (SD) of 36.7 years (11.0); 47.5% were inpatients and 52.5% outpatients; The most prevalent SUDs were with alcohol 54.2%, stimulants 43.6%, cannabis 33.1%, and opioids 14.5%. Patients reported previous treatments for SUD in 71.1% and for ADHD in 56.9%. Other comorbid mental disorders were present in 61.4% of the sample: major depression 31.5%, post-traumatic stress disorder 12.1%, borderline personality disorder 10.2%. CONCLUSIONS: The first baseline results of this international cohort study speak to its feasibility. Data show that many SUD patients with comorbid ADHD had never received treatment for their ADHD prior to enrolment in the study. Future reports on this study will identify the course and potential predictors for successful pharmaceutical and psychological treatment outcomes. TRIAL REGISTRATION: ISRCTN15998989 20/12/2019.

INTRODUCTION: COVID-19 has had a great impact on mental health in the general population. However, few studies have focused on patients with substance use disorders (SUDs). This research aimed to compare the clinical status and substance use patterns of SUD outpatients, before and during confinement due to the COVID-19 pandemic. METHODS: This multicentre study recruited 588 patients (29.2% women; M age = 47.4 ± 11.7 years) in thirteen centres for addiction treatment in Catalonia, Spain. All subjects were evaluated with validated instruments and ad hoc questionnaires. The sample was divided into 3 groups according to how the substance consumption pattern changed during lockdown (maintained pattern, worsened pattern, and improved pattern). RESULTS: More than 62% of the patients maintained or worsened their consumption pattern during confinement, and about 38% improved throughout this time. Diverse factors were associated with the changes in pattern like age, addiction severity, psychological distress during lockdown, social and familial issues, and therapeutic variables. CONCLUSION: The home lockdown during the COVID-19 pandemic was associated with major implications for substance consumption and psychiatric distress among SUD outpatients. Considering this, the need to plan appropriate interventions in cases of similar health crises is highlighted.

Objective COVID-19 and lockdown measures impacted mental health globally and had a particular impact on patients with substance use disorders (SUD). However, the impact of gender, age, and dual diagnosis on consumption patterns and mental health during COVID-19 lockdown among patients with SUD has not been analyzed in depth. Therefore, this study aimed to examine substance use and mental health status during COVID-19 lockdown considering gender, age, and previous dual diagnosis in patients with SUD treated in different outpatient addiction clinics in Catalonia. Methods: Thirteen clinics participated and 588 patients were enrolled in the study, of whom 70.7% were men and 29.3% were women. The mean age was 48 ± 11.3 years, and 63.2% had dual diagnoses. Results: Men reported significantly more frequent alcohol and cocaine consumption during lockdown, while women experienced more anxiety and depressive symptoms. Younger patients more frequently reported consuming cocaine and cannabis, breaking the lockdown rule, worsened family relationships, and reduced incomes. Older patients more frequently reported maintaining abstinence. Previous dual diagnosis was more often associated with benzodiazepine use disorder, less active working during lockdown, and more anxiety and depressive symptoms than not having previous dual diagnosis. Conclusions: Both new psychiatric symptoms and general worsening of existing symptoms were frequent during the lockdown. Differences based on the gender, age, and dual diagnosis of outpatients treated for substance use disorders should be considered in the planning of protection measures such as home confinement.

Alexithymia is highly prevalent in patients with substance use disorders (SUDs) and has been implied in SUD pathogenesis and treatment outcomes. However, the psychometric properties of the most-used instrument for evaluating alexithymia (the 20-item Toronto Alexithymia Scale, TAS-20) have been scarcely studied in relation to SUD patients.

OBJECTIVE: The COVID-19 pandemic and lockdown measures have had a clear psychological impact on families, and specifically those with children with chronic illnesses have reported greater overloads and exhaustion. The objective of this study was to evaluate the exposure, impact and experience of the pandemic on families of pediatric solid organ transplant (SOT) recipients compared to families of healthy children and adolescents. METHODS: We recruited 96 families, 48 with a pediatric SOT recipient and 48 healthy controls, matched by child age and gender. A primary caregiver from each family responded to an online sociodemographic questionnaire and the COVID-19 Exposure and Family Impact Survey (CEFIS), which explores the exposure, impact and experience of the pandemic and lockdown on families. RESULTS: Exposure to the pandemic was greater in families of healthy children and adolescents. The impact was mostly negative in both groups: caregivers reported increased anxiety (76%) and mood disturbances (71.9%) and hindered quality of sleep (64.6%) and health habits (58.3%). On the positive side, family relationships improved. Qualitatively, the SOT group positively perceived isolation and established hygienic measures as protective and destigmatizing, although they reported fear of virus transmission to their child. CONCLUSIONS: The psychological impact of the pandemic has been similar in both groups, although families of transplant recipients have protected themselves more, probably because they are used to prevention measures and they see contagion as a graver risk. Additionally, SOT recipients' families presented some idiosyncratic elements, especially a decrease in their perception of stigma associated with the medical condition.

OBJECTIVE: Cannabis and synthetic cannabinoids (SC) are related to several neuropsychiatric symptoms and disorders, especially psychotic symptoms and disorders. Interestingly, catatonia-like symptoms associated with cannabis and SC have been generally neglected in research and scarcely described despite the clinical repercussions. Hence, this review aims to analyze current clinical publications on catatonia induced by cannabis or SC in a systematized way. Methods: A search using PRISMA guidelines was performed on three databases based on a specific inclusion and exclusion criteria. Results: 11 publications describing 14 patients (10 males; mean age 22.50 ± 6.67 years old) with catatonia apparently precipitated by the use of cannabis (n = 6) or SC (n = 8) were found. Clinical features and treatment are described and discussed. Conclusion: From a clinical perspective, cannabis and SC use may be related to catatonia-like symptoms and catatonia syndrome in the same way these substances (cannabis and SC) are related to induced-psychotic episodes. However, further research will be required to understand the exact nature of that relationship. Additionally, investigations focused on the clinical significance (i.e., prognosis, evolution, and outcomes) of catatonia-like symptoms induced by cannabis and SC use in patients are also needed.

INTRODUCTION: Cocaine dependence is a disorder where relapses are frequently presented and many factors are involved. Furthermore, cocaine dependence is associated with poor health-related quality of life (HRQoL) outcomes. This study aims to explore perceived HRQoL as an indicator of drug relapse in cocaine-dependent patients (CDP). SUBJECTS AND METHODS: A longitudinal study was carried out in CDP during 23 weeks. A consecutive sampling method was applied, 39 participants composed the initial sample (mean age 35.6 years), only 15 participants completed outpatient follow-up period. CDP were assessed with psychiatric and HRQoL instruments (SCID-I, SCID-II, BDI, STAI scale and SF-36) in different points of the study. The patients were followed up, and cocaine relapses were assessed. The sample was divided according with the relapse (early vs. late relapse). Data were compared and analyzed in order to evaluate whether HRQoL measure could be related to cocaine relapse. RESULTS: There are differences in perceived HRQoL measures between CDP with/without early relapse, especially in Mental health and Social functioning dimensions (p<0.05). Furthermore, Late/relapse-patients have higher improvement of HRQoL than patients with early relapse. CONCLUSIONS: Perceived HRQoL might predict early relapse and could be a possible predictor tool of potential future relapses. More research in this field is needed.

PURPOSE: The comorbidity of any substance use disorder and another mental disorder is defined as dual diagnosis. Dual diagnosis is very common and clinical and therapeutic consequences have been described. This cross-sectional study aimed to analyse health-related quality of life (HRQoL) according to clinical characteristics and psychiatric comorbidities in patients with substance dependence. METHODS: A total of 1276 substance-dependent patients seeking treatment were recruited. HRQoL was evaluated by the Short-Form 36 (SF-36) questionnaire. The SCID-I, SCID-II and Conners' adult ADHD diagnostic interview were used to evaluate dual diagnosis. A visual analogue scale was used to measure craving. Bivariate and multivariate analyses were performed, and correction for multiple tests was conducted. RESULTS: Substance-dependent patients had impaired quality of life, especially in the mental component. SF-36 physical and mental component scores were 47.7 ± 10.9 and 36.1 ± 14.1, respectively. Furthermore, 65% of the patients had dual diagnosis, 51% had an Axis I DSM-IV-TR mental disorder and 35% had some personality disorder. Impaired physical quality of life was independently associated with medical condition, age, being female, depressive disorder and anxiety disorder. Depression disorder, any personality disorder, active consumption last month, Attention deficit hyperactivity disorder, anxiety disorder, suicide attempt were independently associated with worse mental quality of life. CONCLUSION: These findings emphasize the significance of dual diagnosis in the impairment of HRQoL in substance-dependent patients, particularly with regard to mental component. In addicted patients with low scores on SF-36, psychiatric comorbidity should be evaluated and treated in an integrated approach.

INTRODUCTION: The relationship among labor difficulties and psychiatric disorders is important and bidirectional. However, current information about the influence of psychiatric disorders in temporary work disability in Spain is inconclusive. For this reason, we aimed to describe the prevalence of the conclusions of psychiatric expert’s reports including maintain o revoke the temporary disability (TD). We also aimed to compare sociodemographic, clinical and therapeutic variables according with the decision of maintain or revoke this condition. METHODOLOGY: A descriptive study was conducted in psychiatric patients that were examined by psychiatric experts during one year. At the examination time, the patients had a sick leave mean of 5 months. The psychiatric experts assessed their ability to work according to the interference of the psychiatric symptoms. RESULTS: A total of 380 patients were included (66.8% women, 42±10.9 years), 87.9% had a result of revoke the temporary work disability. No sociodemographic or therapeutic factors were associated with the continuity of sick leave. The most common diagnosis of patients who obtained a revoked temporary work disability was adjustment disorder (66.2% vs 13%, p=0.001) and patients who maintained the temporary work disability was major depressive disorder (45.7% vs 3.9%, p=0.001). CONCLUSIONS: After a psychiatric expert’s examination the most of the results suggest to revoke the temporary work disability. Major depressive disorder is the most commonly diagnostic associated to continue sick leave.

INTRODUCTION: A bidirectional relation between substance use and insomnia has been described, although there are few studies examining insomnia in the population of people with addiction. The aim of this study was to describe the prevalence of insomnia during active substance use in patients with addiction and its associated clinical features. PATIENTS AND METHODS: Descriptive study in patients diagnosed with substance dependence disorder admitted to a Hospital Detoxification Unit. The existence of insomnia prior to admission was assessed using the Oviedo Sleep Questionnaire (OSQ). Demographic variables, consumptionrelated clinical variables, and diagnostic variables were collected and the SCID-I and -II (Structured Clinical Interview for DSM-IV) and CAADID (Conners’ Adult ADHD Diagnostic Interview for DSM-IV) were administered to evaluate the psychiatric diagnoses. Bivariate and multivariate analyses were made of the data. RESULTS: 481 patients (72.6% men, age 40.6±10.1 years) were enrolled. 64.3% of the patients reported insomnia during active substance use. The most common type of insomnia was fragmented nocturnal sleep (49.9%). The factors significantly associated with insomnia were polysubstance drug use, medical comorbidities (most notably, infectious diseases), anxiety disorder, personality disorder (particularly cluster C), a greater number of previous admissions for detoxication, and early age at onset of substance use. CONCLUSIONS: Insomnia is highly prevalent in patients with addiction during active use of the substance. Fragmented nocturnal sleep was the most common type of insomnia. Patients with addiction and comorbid anxiety disorder, medical comorbidity, and early onset of dependence were more likely to experience insomnia.

The relapse rate after discharge from inpatient detoxification is high. The objective of this pilot study is to assess the sociodemographic, clinical and therapeutic factors associated with maintaining abstinence in patients who participated in a brief motivational interviewing group during admission for detoxification. A total of 46 patients, diagnosed substance dependent according to DSM -IV, and admitted to the Hospital Detoxification Unit, participated in a brief motivational interviewing group. Sociodemographic, clinical, motivation to change (University of Rhode Island Change Assessment, URICA) and satisfaction with the treatment group (Treatment Perceptions Questionnaire, CPT) data were collected. Abstinence and treatment retention two months after discharge were assessed by weekly telephone calls. A survival analysis was performed. Being male, having more cognitions of the maintenance stage of change at discharge, being satisfied with group therapy and therapist during hospitalization are associated with longer abstinence after discharge. The brief motivational interviewing group approach with patients admitted for detoxification is related to greater likelihood of maintaining abstinence and subsequent treatment retention.
La tasa de recaída en el consumo al alta de una Unidad de Desintoxicación Hospitalaria es elevada. El objetivo de este estudio piloto es valorar los factores sociodemográficos, clínicos y terapéuticos asociados al mantenimiento de la abstinencia de pacientes que han participado en un grupo psicoterapéutico breve de corte motivacional durante su ingreso para la desintoxicación.Un total de 46 pacientes con diagnóstico de trastorno por dependencia a sustancias, según DSM-IV, ingresados en Unidad de Desintoxicación Hospitalaria participaron en un grupo breve de corte motivacional. Se midieron variables sociodemográficas y clínicas, así como la motivación al cambio (University of Rhode Island Change Assessment, URICA) y la satisfacción con el tratamiento grupal (Cuestionario de Percepciones de Tratamiento, CPT). El mantenimiento de la abstinencia y la retención al tratamiento, dos meses tras el alta, se evaluaron mediante llamadas telefónicas semanales. Se realizó un análisis de supervivencia. Los resultados muestran que ser varón, tener cogniciones del estadio de mantenimiento del cambio al alta y tener una buena satisfacción con la terapia grupal y su terapeuta durante el ingreso, se asocia con mayor tiempo en abstinencia tras el alta. El abordaje psicoterapéutico grupal breve de corte motivacional, en pacientes ingresados para la desintoxicación, se relaciona con mayor probabilidad de mantenimiento de abstinencia y de retención al tratamiento posterior.

OBJECTIVE: Neuroticism and impulsivity are the personality variables most consistently associated with drug-dependent patients. To date, no data mining procedures have been applied to explore the differential role of personality variables in this population. METHODS: The personality profile of 336 drug-dependent patients was compared with that of a sample of community participants in the context of a decision tree learning approach using the Alternative Five Factor Model. The resulting discriminant model was cross-validated. RESULTS: Neuroticism and impulsivity were the most relevant variables in the resulting model, but their association appeared to be hierarchically organized. In the personality characterization of these patients, neuroticism became the main discriminant dimension, whereas impulsivity played a differential role, explained by means of an interaction effect. Decision tree learning models appear to be a heuristic theoretical and empirical approximation to the study of relevant variables, such as personality traits, in drug-dependency research.

Background: The COVID-19 pandemic has impacted the mental health of patients with substance use disorder (SUD). However, few longitudinal studies have been done which examine associations between the pandemic, SUD patients' mental health and their drug use. Objectives: This study aimed to examine duration of abstinence according to psychiatric status among SUD outpatients followed-up for 18 months from the pandemic related lockdown. Methods: A follow-up study of 316 SUD outpatients was undertaken. Sociodemographic features, and clinical and consumption related variables were recorded. Pre, during and post lockdown information was evaluated. Abstinence/substance use was monitored at the patient's scheduled follow-up appointments, and psychiatric disorders and psychological variables were revaluated at 18 months. Results: Survival analyses were used to compare the duration of abstinence (in months) from the beginning of the lockdown. It was observed that 70% of patients consumed the main substance for which they were being treated at some point during the follow-up. Men, younger patients, those with more symptoms of anxiety and personality disorders, and patients who experienced increased craving during follow-up, showed shorter duration of abstinence. While patients who had previously maintained at least one year of abstinence, achieved better results. Conclusions: During the first year and a half of the pandemic, SUD outpatients presented alterations in mental health, such us anxiety, depression and maladaptive personality traits and a high rate of relapse. For this reason, despite the health and social crisis and their restrictive measures, a comprehensive treatment should be ensured.
ABSTRACT
Substance use disorder (SUD) is a global health problem with a significant impact on individuals and society. The presentation of SUD is diverse, involving various substances, ages at onset, comorbid conditions, and disease trajectories. Current treatments for SUD struggle to address this heterogeneity, resulting in high relapse rates. SUD often co-occurs with other psychiatric and mental health-related conditions that contribute to the heterogeneity of the disorder and predispose to adverse disease trajectories. Family and genetic studies highlight the role of genetic and environmental factors in the course of SUD, and point to a shared genetic liability between SUDs and comorbid psychopathology. In this study, we aimed to disentangle SUD heterogeneity using a deeply phenotyped SUD cohort and polygenic scores (PGSs) for psychiatric disorders and related traits. We explored associations between PGSs and various SUD-related phenotypes, as well as PGS-environment interactions using information on lifetime emotional, physical, and/or sexual abuse. Our results identify clusters of individuals who exhibit differences in their phenotypic profile and reveal different patterns of associations between SUD-related phenotypes and the genetic liability for mental health-related traits, which may help explain part of the heterogeneity observed in SUD. In our SUD sample, we found associations linking the genetic liability for attention-deficit hyperactivity disorder (ADHD) with lower educational attainment, the genetic liability for post-traumatic stress disorder (PTSD) with higher rates of unemployment, the genetic liability for educational attainment with lower rates of criminal records and unemployment, and the genetic liability for well-being with lower rates of outpatient treatments and fewer problems related to family and social relationships. We also found evidence of PGS-environment interactions showing that genetic liability for suicide attempts worsened the psychiatric status in SUD individuals with a history of emotional physical and/or sexual abuse. Collectively, these data contribute to a better understanding of the role of genetic liability for mental health-related conditions and adverse life experiences in SUD heterogeneity.

BACKGROUND: Cocaine-induced psychosis (CIP) is among the most serious adverse effects of cocaine. Reduced serum brain-derived neurotrophic factor (BDNF) levels have been reported in schizophrenia and psychosis; however, studies assessing the involvement of BDNF in CIP are lacking. METHODS: A total of 22 cocaine-dependent patients (aged 33.65 ± 6.85) who had never experienced psychotic symptoms under the influence of cocaine (non-CIP) and 18 patients (aged 34.18 ± 8.54) with a history of CIP completed a 2-week detoxification program in an inpatient facility. Two serum samples were collected from each patient at baseline and at the end of the protocol. Demographic, consumption and clinical data were recorded for all patients. A paired group of healthy controls was also included. RESULTS: At the beginning of the detoxification treatment, serum BDNF levels were similar in both the non-CIP and the CIP groups. During early abstinence, the non-CIP group exhibited a significant increase in serum BDNF levels (p = 0.030), whereas the CIP group exhibited a decrease. Improvements in depression (Beck Depression Inventory, BDI, p = 0.003) and withdrawal symptoms (Cocaine Selective Severity Assessment, CSSA, p = 0.013) show a significant positive correlation with serum BDNF levels in the non-CIP group, whereas no correlation between the same variables was found in the CIP group. CONCLUSIONS: This study suggests that BDNF plays a role in the transient psychotic symptoms associated with cocaine consumption. In the non-CIP group, the increase in serum BDNF appears to be driven by the effects of chronic cocaine consumption and withdrawal. In contrast, patients with CIP share some of the neurotrophic deficiencies that characterize schizophrenia and psychosis.

BACKGROUND AND OBJECTIVES: Attention deficit hyperactivity disorder (ADHD) is highly prevalent among drug abusers. We studied the psychiatric comorbidity and characteristics of cocaine use in relation to the presence of ADHD among patients with cocaine dependence. METHODS: A total of 200 cocaine-dependent patients attending an Outpatient Drug Clinic participated in the study. A systematic evaluation of ADHD (CAADID-II), the severity of addiction (EuropASI) and other axes I and II psychiatric disorders was made (SCID-I and SCID-II). A descriptive, bivariate, and multivariate analysis of the data was performed. RESULTS: In the multivariate analysis, the identified risk factors for the development of ADHD were a history of behavioral disorder in childhood (OR: 3.04), a lifetime history of cannabis dependence in the course of life (OR: 2.68), and age at the start of treatment (OR: 1.08). The bivariate analysis showed ADHD to be associated with other factors such as male gender, age at start of cocaine use and dependence, the amount of cocaine consumed weekly, increased occupational alteration, alcohol consumption, general psychological discomfort, depressive disorder, and antisocial personality disorder. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: We conclude that ADHD is associated with increased psychiatric comorbidity and greater severity of addiction.

BACKGROUND: Psychotic symptoms are common among cocaine users. METHODS: An observational naturalistic study on the effects and events of intravenous cocaine use in a drug consumption room was carried out; the patients were diagnosed of cocaine dependence (according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision). RESULTS: Twenty-one patients, 81% men self-injected cocaine 375 times. Psychotic symptoms were observed in 62% of the patients and 21% of the self-injections; delusions were observed in 9.3%, psychotic self-reference with insight in 9.1%, illusions in 6.4%, and hallucinations in 5.3%. A higher presence of psychotic symptoms was noted with cannabis used in the previous month (76.9% versus 44.4%; P = .001) (no psychotic symptoms group); also, a greater use of benzodiazepines was observed: 75.6% versus 63.6% (P = .046). Lower use of methadone in the group with psychosis was observed: 75.6% versus 97.3% (P = .001). Motor alterations were tremor 58%, stereotyped movements 24%, and behaviour alteration 6%, significantly more frequent in the psychotic group. CONCLUSIONS: Thus, there was a high frequency of psychotic symptoms after intravenous cocaine use; patients with psychotic symptoms reported higher use of cannabis and benzodiazepines in the previous month and lower use of methadone. More tremors and stereotyped movements were observed in the group with psychotic symptoms. It is necessary to give a special approach to cocaine intravenous users.

The comorbidity between attention deficit hyperactivity disorder (ADHD) and substance use disorders is very common. A review of literature addressing prevalence, clinical features and treatment of the comorbidity between ADHD and CNS depressants was conducted. The prevalences found have a wide range (4.5% to 58%). ADHD has been associated with greater severity of addiction, early onset of consumption and addiction, more psychiatric comorbidity and more chronicity. In drug-dependent patients the diagnosis is a complex process because the frequent overlap of symptoms. The screening instruments should be used with caution. Drug therapy has shown efficacy in reducing ADHD symptoms, but there is no consensus regarding their influence on substance use. However, results should be interpreted cautiously, because the samples are small. Psychoeducational interventions are relevant, but treatment outcomes have not been described or studied systematically.

Suicidal behaviors are common among patients with substance use disorders (SUD). However, the prevalence and clinical factors related to suicide behaviors among patients who have had substance-induced psychosis (SIP) is unknown. This study aims to explore the prevalence, clinical features, and factors related to lifetime suicidal ideation (SI) and suicide attempts (SA) in patients who have had SIP across their lifetime. A cross-sectional study was conducted in an outpatient center for addiction treatment between 01/01/2010 and 12/31/2021. 601 patients were evaluated with validated scales and questionnaires (79.03% males; M age 38.11±10.11 years). The prevalence of SI and SA was 55.4% and 33.6%, respectively. SI was independently related to any type of lifetime abuse, depressive spectrum disorders, benzodiazepine use disorder, borderline personality disorder, and the level of depressive symptoms. SA was independently associated with lifetime physical abuse, benzodiazepine use disorder, the number of psychotic symptoms, borderline personality disorder, and the level of depressive symptoms. The main factors related to SI and SA in those patients should be evaluated in daily clinical practice and considered in any approach to clinical practice as well as in health policies targeting suicide prevention.
