Psychiatric comorbidity, psychological distress, and quality of life in gamma-hydroxybutyrate-dependent patients

Unity in diversity: A systematic review on the GHB using population

BACKGROUND

Over the past decades gamma-hydroxybutyrate (GHB) has emerged as a popular drug with high potential of (ab)use due to its euphoric and relaxing effects. An overview of different populations using GHB is urgently needed, since this would enable development of adequate prevention and treatment policies to diminish the risks associated with GHB use. We systematically reviewed literature on different GHB using populations, comparing demographic characteristics, GHB use patterns, psychosocial aspects and psychiatric comorbidity.

METHODS

We conducted a systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines using Rayyan software. Original studies published from January 1997 up to October 2019 on GHB use were included. Out of 80 full-text articles, 60 articles of 51 unique studies were included. Most studies included people using GHB 1) presenting at emergency departments (n = 22), 2) recruited from the general population (n = 11), or 3) presenting at addiction care (n = 8).

RESULTS

Three main sub-populations of people using GHB are described in the literature: people using GHB recreationally without adverse effects; people using GHB recreationally with adverse effects, and people with dependence on GHB. These groups show considerable overlap in gender, age range, and comorbid substance use, as well as amount of GHB use per occasion. Differences are related to frequency and function of GHB use, the number of comas experienced, as well as work status, and psychiatric comorbidity.

CONCLUSION

Policy interventions should aim at preventing the transition from recreational substance use to GHB use, as most users are experienced recreational substance users prior to starting GHB use. When people use GHB regularly, interventions should aim at reducing the level of GHB use and preventing GHB use-related harm. Longitudinal studies and population-based probability sampling are required for more insight in the dynamics of GHB use in different sub-populations, and the transition from one group to the other, ultimately leading to dependence on GHB.

The rise of new psychoactive substances and psychiatric implications: A wide-ranging, multifaceted challenge that needs far-reaching common legislative strategies

The ever-growing number of novel psychoactive substances (NPS) that have been surfacing globally, as well as related changes in drug abuse trends, undoubtedly constitute a difficult and multifaceted challenge for psychiatry. The intake and abuse of such substances has been linked to a risk of psychopathological disturbances, which stem from imbalances of a range of neurotransmitter pathways and receptors. Through an analysis of relevant research articles and reviews (particularly those outlining NPS neurological and cerebral mechanisms of action and psychopathological consequences arising from NPS abuse; research papers more closely focused on chemical/pharmacological aspects have been ruled out), through a systematic analysis of Pubmed, Medline, PsycLIT and EMBASE literature, as well as data released by health care institutions and drug enforcement agencies (among which the World Health Organization, the United Nations Office on Drugs and Crime, the European Monitoring Centre for Drugs and Drug Addiction, Eurojust, the Novel Psychoactive Treatment UK Network, the Court of Justice of the European Union), the authors aimed to elaborate on the most relevant data relative to NPS-related psychiatric effects, focusing on the conceptual and definition-related complexities inherent to NPS, clinical management and motivations for NPS use; moreover, an effort has been made to highlight the possible measures in order to tackle the unremitting rise of such elusive and potentially harmful substances.

Characteristics and circumstances of death related to gamma hydroxybutyrate (GHB)

Introduction: Gamma hydroxybutyrate (GHB) has gained substantial popularity as an illicit recreational drug. The current study aimed to: (1) determine the characteristics and circumstances of death of all recorded cases of GHB-related death in Australia, 2001-2019; (2) determine the toxicology of cases; and (3) determine major organ pathology.Methods: Retrospective study of all Australian cases in which GHB was a mechanism contributory to death retrieved from the National Coronial Information System (n = 74). Information was collected on cause of death, demographics, circumstances of death, toxicology and major organ pathology.Results: The mean age was 31.5 years and 70.3% were male. The predominant circumstance of death was accidental drug toxicity (79.7%), including five cases attributed to a combination of toxicity and natural disease. Other deaths were due to trauma (12.2%) and suicide (8.2%). The fatal incident overwhelmingly occurred in a home environment (82.4%). In all cases, GHB was consumed orally. The median GHB blood concentration was 210 mg/L (range 13-1350 mg/L), and was significantly higher in toxicity cases than others (258 vs. 98 mg/L, p < .01). Other substances were present in 92.2%, most commonly psychostimulants (64.1%), hypnosedatives (28.2%) and alcohol (20.3%). Resuscitation was attempted in 20.3% of cases. Acute pneumonia (36.7%) and aspiration of vomitus (30.6%) were common.Conclusions: The typical case was a young male, who swallowed GHB and used it with other substances, most commonly at home. While acute drug toxicity was the most common cause of death, there was a substantial minority due to trauma or suicide.

Demographic and Clinical Characteristics of Regular GHB-Users with and without GHB-Induced Comas

Gamma hydroxybutyric acid (GHB) has been used recreationally for nearly three decades and its chronic use is frequently associated with serious adverse events including GHB-intoxication with GHB-induced comas. Moreover, despite its low prevalence, the number of individuals with GHB-use disorders is steadily increasing. However, the risk-factors associated with chronic GHB-use or the development of a GHB-use disorders remain poorly understood. Purpose: This study aims to profile two types of GHB-users, those with and those without GHB-induced comas. Methods: We included 27 GHB users with ≥4 GHB-induced comas (GHB-Coma), 27 GHB users without a coma (GHB-NoComa), and 27 polydrug users who never used GHB (No-GHB). Participants completed self-reported questionnaires in order to assess their demographic and clinical features, and their use profile of GHB and other drugs. Results: The typical GHB user in our sample was young, single, living alone, well-educated, and a student. The GHB-Coma group had lower self-control and reported higher negative affect than the GHB-NoComa group. GHB-Coma participants were heavier GHB users and mostly used GHB alone at home, whereas the GHB-NoComa group mostly used GHB with friends and in nightclubs. Remarkably, the majority of participants were not concerned about potential neurocognitive impairments induced by GHB-intoxication and/or GHB-induced comas. Conclusion: In this assessment, different profiles for recreational users with and without GHB-induced comas were well expressed. Their description contributes to a better understanding of the risk factors associated with recreational GHB-use, GHB-induced coma, and the development of GHB-use disorders.

A New Psychoactive Substance, Gamma Hydroxybutyrate (GHB): A Case Report

Gamma Hydroxybutyrate (GHB) is a central nervous system depressant effecting GABA-B receptors. GHB is taken along with other psychoactive substances like alcohol, cocaine, ecstasy, and amphetamines especially during parties. Due to the fact that it has been linked to sexual assault, GHB has drawn attention in recent years. This substance is often taken by youngsters and results in euphoric states of mind, signs of relief, easiness in communication, increases in sexual appetite, and experiences of different states of mind. Dizziness, hypotension, bradycardia, nauseation, and vomiting are typical toxication symptoms of GHB. Also, epileptic seizures, respirotary depression, and deaths have been reported as a result of taking GHB. It is widely known that the use of GHB in our country has increased gradually. This case report is important as it summarizes the anamnesis, penetration, and clinical symptoms of GHB. In order to prevent the use of GHB, it would be appropriate to develop psycho-education methodologies, establish legislative regulations, and include GHB tests in substance screening analyses.

Influence of Gamma-Hydroxybutyric Acid-Use and Gamma-Hydroxybutyric Acid-Induced Coma on Affect and the Affective Network

BACKGROUND

Gamma-hydroxybutyric acid (GHB) is a drug of abuse associated with increased emergency room attendances, due to GHB-induced comas. Withdrawal from GHB often increases social anxiety and is linked to alterations in emotion processing. However, little is known about the effects of GHB-use and GHB-induced comas on affect regulation in humans.

OBJECTIVES

We aimed to assess the effect of GHB-use and GHB-induced comas on the affective network.

METHOD

We recruited 27 GHB users with ≥4 GHB-induced comas (GHB-Coma), 27 GHB users without a GHB-induced coma (GHB-NoComa), and 27 polydrug users who never used GHB (No-GHB). Participants completed self-report questionnaires assessing negative affect (depression, anxiety and stress) and performed an emotional face matching task during functional magnetic resonance imaging to probe activity of the amygdala and the hippocampus.

RESULTS

The GHB-Coma group reported higher levels of depression, anxiety, and stress; showed decreased activity of the hippocampus; and increased functional connectivity of the left hippocampus with the left fusiform gyrus and a cluster on the left temporal-parietal-occipital junction, when compared with the 2 other groups. The GHB-NoComa group showed decreased functional connectivity of the left hippocampus with the amygdala in comparison with the No-GHB group.

CONCLUSIONS

GHB-use but in particular GHB-induced comas, are associated with altered emotion identification and hippocampal functioning. Awareness campaigns are required to raise consciousness about the adverse effects of GHB-induced comas on affect regulation, despite the absence of subjective side effects.

Inpatient Gamma-Hydroxybutyrate Detoxification: A Case Report Describing Day-to-day Therapeutic Management

BACKGROUND

Gamma-hydroxybutyrate (GHB) is a synthetic drug increasingly used by consumers of psychoactive substances. The sought after psychoactive effects of GHB have resulted in an increase in recreational use in Europe. GHB is considered to have a high dependence potential, and abrupt discontinuation after long-term use can result in a severe withdrawal syndrome. Despite a large number of publications related to GHB withdrawal and detoxification, to date, no evidence-based protocol or consensual international therapeutic guidelines are available (over and above the administration of benzodiazepines). We hereby present a day-to-day description of inpatient GHB detoxification management, from admission to discharge.

CASE SUMMARY

This case report pertains to a 47-year-old patient hospitalized for a severe GHB use disorder. The patient had independently made several unsuccessful attempts to stop GHB use. Following to these failures, the patient was oriented to our addiction department for inpatient detoxification. Withdrawal symptoms appeared 4 hours after the last dose of GHB, and consisted of diaphoresis, coenesthetic hallucinations, tremors, motor instability, tachycardia, and a hypertensive peak. Symptoms were successfully managed with diazepam titration and nonpharmacological treatment. The duration of hospitalization was 13 days. At discharge, detoxification was complete and the patient was engaged in relapse prevention therapy. Three months after discharge, the patient had maintained abstinence.

CONCLUSIONS

GHB withdrawal, which can be severe, is better prevented or attenuated by daily medical monitoring and adjustment of treatment dosage. Failure of outpatient detoxification should be included in the indication criteria in the guidelines for inpatient detoxification.

Pharmacological Treatment in γ-Hydroxybutyrate (GHB) and γ-Butyrolactone (GBL) Dependence: Detoxification and Relapse Prevention

The misuse of γ-hydroxybutyrate (GHB) for recreational purposes has resulted in an increase in GHB-related problems such as intoxications, dependence and withdrawal in several countries in Europe, Australia and the US over the last decade. However, prevalence rates of misuse of GHB and its precursor, γ-butyrolactone (GBL), are still relatively low. In this qualitative review paper, after a short introduction on the pharmacology of GHB/GBL, followed by a summary of the epidemiology of GHB abuse, an overview of GHB dependence syndrome and GHB/GBL withdrawal syndrome is provided. Finally, the existing literature on management of GHB detoxification, both planned and unplanned, as well as the available management of GHB withdrawal syndrome, is summarized. Although no systematic studies on detoxification and management of withdrawal have been performed to date, general recommendations are given on pharmacological treatment and preferred treatment setting.
