Dysregulation of Plasma Growth Factors and Chemokines in Cocaine Use Disorder: Implications for Dual Diagnosis with Schizophrenia and Antisocial Personality Disorder in an Exploratory Study.

[PMID: 38768577 PMCID: PMC11210571 DOI: 10.1159/000536265] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/16/2023] [Accepted: 01/09/2024] [Indexed: 05/22/2024]
Abstract
INTRODUCTION Dual diagnosis in individuals with cocaine use disorders (CUDs) presents a mental health challenge marked by an increased susceptibility to disabling morbidities and premature mortality. Despite extensive research on depression and anxiety, other prevalent comorbidities, such as psychotic and personality disorders, have received less attention. This study explores inflammation-related mediators as potential biomarkers for CUD and dual diagnosis with schizophrenia (SCZ) or antisocial personality disorder (APD). METHODS This exploratory study included 95 participants, comprising 40 healthy subjects and 55 abstinent patients with CUD. Lifetime CUD was diagnosed either as single diagnosis (CUD group, N = 25) or as a dual diagnosis (DD group. N = 30) with SCZ (CUD+SCZ subgroup) or APD (CUD+APD subgroup). Participants were clinically assessed, and the plasma concentrations of growth factors (i.e., G-CSF, BDNF, and VEGF-A) and chemokines (i.e., CCL11/eotaxin-1, CCL2/MCP-1, and CXCL12/SDF-1) were determined and log(10)-transformed for analysis. RESULTS Growth factors and chemokines were dysregulated by CUD and psychiatric diagnoses. Specifically, patients in the CUD group exhibited significantly lower concentrations of G-CSF and CCL11/eotaxin-1 than the control group. In contrast, the DD group showed significantly higher concentrations of all analytes than both the CUD and control groups. Additionally, no differences in these analytes were observed between the CUD+SCZ and CUD+APD subgroups within the DD group. Regarding cocaine-related variables, significant associations were identified in the CUD group: an inverse correlation between the age at first cocaine use and the concentrations of BDNF and CCL2/MCP-1; and a positive correlation between the duration of the cocaine abstinence and the concentrations of BDNF and CCL11/eotaxin-1. Lastly, a logistic regression model incorporating all these analytes demonstrated high discriminatory power in distinguishing patients with CUD alone from those with dual diagnosis. CONCLUSIONS Individuals with dual diagnosis of CUD exhibit elevated concentrations of growth factors and chemokines, distinguishing them from those with CUD alone. It is unclear whether the differences in these inflammatory mediators are specific to the presence of SCZ and APD. The study highlights potential biomarkers and associations, providing valuable insights into the intricate interplay of CUD and psychiatric disorders to enhance clinical diagnosis and therapeutics.

Cocaine Effect Expectancies among Patients with Cocaine Use Disorder with and without Adult Attention Deficit Hyperactivity Disorder: Are There Any Relevant Differences? J Psychoactive Drugs 2024; 56:76-87. [PMID: 36480506 DOI: 10.1080/02791072.2022.2151951] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2022] [Revised: 09/05/2022] [Accepted: 09/23/2022] [Indexed: 12/14/2022]
Abstract
Cocaine use could be modulated by drug expectancies based on previously experienced subjective effects. Some patients perceive a paradoxical calming effect after cocaine use. This study was performed to explore cocaine effect expectancies in patients diagnosed with cocaine use disorder, with and without co-occurring adult attention deficit hyperactivity disorder (ADHD). Secondly, we sought to empirically determine the presence of this paradoxical calming effect after cocaine use in patients with co-occurring adult ADHD to identify the individuals most at risk of cocaine use and relapse. Cross-sectional study using a consecutive sampling method of patients diagnosed with cocaine use disorder (n = 221) treated at public therapeutic communities in Andalusia (Spain). Participants completed a battery of instruments to assess the following variables: cocaine effect expectancies, paradoxical calming effect, adult ADHD, and other co-occurring psychiatric disorders. A multivariate binary logistic regression analysis showed that two variables, the paradoxical calming effect and antisocial personality disorder (ASPD), were independently associated with the probability of being diagnosed with adult ADHD (OR = 3.43, 95% CI = 1.88-6.26 and OR = 3.42, 95% CI = 1.30-8.95, respectively). The presence of a paradoxical calming reaction to cocaine and/or a diagnosis of ASPD in patients with cocaine use disorder increases the diagnostic suspicion of co-occurring adult ADHD.

Abstract
Cocaine addiction is frequently associated with different psychiatric disorders, especially schizophrenia and antisocial personality disorder. A small number of studies have used prepulse inhibition (PPI) as a discriminating factor between these disorders. This work evaluated PPI and the phenotype of patients with cocaine-related disorder (CRD) who presented a dual diagnosis of schizophrenia or antisocial personality disorder. A total of 74 men aged 18–60 years were recruited for this research. The sample was divided into four groups: CRD (n = 14), CRD and schizophrenia (n = 21), CRD and antisocial personality disorder (n = 16), and a control group (n = 23). We evaluated the PPI and other possible vulnerability factors in these patients by using different assessment scales. PPI was higher in the CRD group at 30 ms (F(3, 64) = 2.972, p = 0.038). Three discriminant functions were obtained which allowed us to use the overall Hare Psychopathy Checklist Revised score, reward sensitivity, and PPI at 30 ms to predict inclusion of these patients in the different groups with a success rate of 79.7% (42.9% for CRD, 76.2% for CRD and schizophrenia, 100% for CRD and antisocial personality disorder, and 91.3% in the control group). Despite the differences we observed in PPI, this factor is of little use for discriminating between the different diagnostic groups and it acts more as a non-specific endophenotype in certain mental disorders, such as in patients with a dual diagnosis.

Psychiatric factors affecting recovery after a long term treatment program for substance use disorder. Psychiatry Res 2019; 276:283-289.

Abstract
Psychiatric comorbidity can negatively impact the course of addictions. Psychiatric features of patients who continued treatment after the first stage of an addiction program have not been sufficiently analysed. Therefore, only these patients were included in order to compare psychiatric comorbidity and clinical factors between patients who were able or not to complete a long term substance-free program. Treatment-completion status of 245 patients was systematically recorded. Addiction severity, psychiatry comorbidity, and psychological symptoms were evaluated. No significant differences were found regarding comorbid psychiatric diagnoses and the completion of the treatment. Longer treatment duration (OR: 1.22; p < 0.01), higher educational level (OR: 2.37; p = 0.02), and cocaine dependence as main substance (OR: 3.68; p < 0.01) were found to be related to increased likelihood in completing the treatment. Patients with higher severity of alcohol consumption (OR: 0.06; p = 0.02) and more depressive symptoms (OR: 0.95; p = 0.01) completed the treatment less frequently. Moreover, differences regarding employment problems, treatment facilities, anxiety symptoms, dysfunctional impulsivity, and mental HRQoL were found. It is concluded that comorbid psychiatric diagnoses do not determine treatment outcomes. However, therapeutic and psychological factors have a major influence on the likelihood to complete a long-term treatment program.

Abstract
For decades, clinicians and researchers have recognized that borderline personality disorder (BPD) and substance use disorders (SUDs) are often diagnosed within the same person (e.g., (Gunderson JG. Borderline personality disorder: A clinical guide. Washington, D.C.: American Psychiatric Press, 2001; Leichsenring et al., Lancet 377:74-84, 2011; Paris J. Borderline personality disorder: A multidimensional approach. American Psychiatric Pub, 1994; Trull et al., Clin Psychol Rev 20:235-53, 2000)). Previously, we documented the extent of this co-occurrence and offered a number of methodological and theoretical explanations for the co-occurrence (Trull et al., Clin Psychol Rev 20:235-53, 2000). Here, we provide an updated review of the literature on the co-occurrence between borderline personality disorder (BPD) and substance use disorders (SUDs) from 70 studies published from 2000 to 2017, and we compare the co-occurrence of these disorders to that documented by a previous review of 36 studies over 15 years ago (Trull et al., Clin Psychol Rev 20:235-53, 2000).

Abstract
OBJECTIVE Comorbidity between personality disorders (PD) and substance-use disorders (SUD) is one of the most common findings in the psychiatric field. The patients with Cluster C disorders present maladjustment traits often characterized by high levels of anxiety. The main aim of this study was to find evidences about higher anxiety and depression prevalence on Cluster C than others Clusters, analyzing similarities and differences within, with other Cluster A and B PD patients and patients without PD. METHOD A total of 822 substance dependent patients (ages18-78; Mean = 38.35, SD = 10.14) completed the structured clinical interview for DSM-IV Axis I and Axis II disorders, Beck Depression Inventory, and State-Trait Anxiety Inventory. RESULTS Results supported poly-consumption in Cluster C patients, being greater alcohol consumption as well as abuse of both stimulants and depressants. Anxiety and depression did not show just one pattern for all patients with SUD-Cluster C PD. There was a relation between anxiety and depression for all the groups except for the Dependent-PD. CONCLUSION Interventions should focus on aspects like depression and anxiety more than on the substance consumed.

Abstract
BACKGROUND The aim of this study is to describe the features of cocaine-dependent patients who have had cocaine-induced tactile/somatic hallucinations (CITSH), and to analyze the association with addiction-related variables and psychiatric comorbidity, comparing patients with CITSH, patients with cocaine psychotic symptoms (CIP) and no CITSH, and patients without any psychotic symptom. METHOD A cross-sectional study was conducted in 767 cocaine-dependent patients in an outpatient treatment center for addictions. The following data were obtained: sociodemographic characteristics, CIP information, addiction-related variables and psychiatric comorbidity. A bivariate and multivariate analysis was performed. RESULTS Of the whole sample, 6.6% reported CITSH at some point of their lives, 48.4% had suffered some CIP other than CITSH, and 45% had not experienced any psychotic symptom. According to multivariate analysis, risk of overdose increases by 12.1 (OR) times the probability of having had CITSH compared patients with CIP-no-CITSH. Other variables associated to patients with CITSH were: age of drug use onset, presence of episodes of overdose, prevalence of psychotic disorder induced by cocaine. In general, in all variables studied, patients with CITSH presented worse clinical features (addiction variables and psychiatric comorbidity) than patients with CIP without CITSH and non-CIP group. CONCLUSION CITSH are usually associated with other psychotic symptoms induced by cocaine. The patients who experienced CITSH are more severe cases compared both with patients with CIP without CITSH and patients without CIP. Increased risk of overdose is an important issue in this type of patients.
