Effects of age and gender on the relationship between alcohol use disorder and somatic diseases: a national register study in Norway

Objective - This study aimed to examine how age and gender moderate the associations between alcohol use disorders (AUD) and several somatic diseases. Design and setting - We performed a retrospective, register-based cohort study with 6-year follow-up of patients with AUD and the general population. Data were acquired from the Norwegian Patient Registry. Cox regressions were used to estimate HRs of somatic diseases. Participants - Patients with AUD (17 023; 0.4%) were compared with the population without AUD (4 271 559; 99.6%), with adults aged 18 years or older who were registered residents of Norway on 1 January 2008. Main outcomes - Dichotomous variables of 12 specific somatic diseases (cardiovascular diseases, endocrine, nutritional, and metabolic diseases, cancer, and infectious diseases) were assessed. Diagnoses were set in specialist healthcare services. Results Patients with AUD, compared with a population without AUD, experienced a significantly greater burden of all studied somatic diseases. Middle-aged adults with AUD had increased risks (p0.05). Males with AUD had significantly higher risks for pulmonary heart diseases (HR=3.9, 95% CI 3.3 to 4.6) and metabolic disorders (HR 4.7, 95% CI 4.5 to 5.0), while females with AUD had a significantly higher risk for viral hepatitis (HR=4.4, 95% CI 3.8 to 5.1). Conclusions - Age moderated the associations between AUD and most somatic diseases, with middle-aged adults with AUD having a greater increased risk of somatic diseases compared with younger and older adults with AUD. Gender only moderated associations between AUD and pulmonary heart diseases, metabolic disorders and viral hepatitis. This has implications for the prioritisation of somatic resources among patients with AUD

Factors associated with the level of prolactin in patients under remission from Alcohol Use Disorder: A gender perspective

Background: Prolactin mirrors the dopaminergic activity in the brain which is key to understanding alcohol use disorders (AUD). Still, patients with AUD are a heterogenous group and there seem to be gender differences in the relationship between alcohol use and the level of prolactin. In this study, we examined gender-wise relationship of alcohol use trait- and state-related factors with the level of prolactin among AUD inpatients in remission. Methods: This cross-sectional study examined the level of prolactin along with general patient characteristics and alcohol use trait- and state-related factors that could influence the level of prolactin in 112 AUD inpatients at three rehabilitation clinics in Norway. Logistic regression was performed to identify the gender-specific predictors of level of prolactin. Results: Male and female AUD patients had similar level of prolactin. Among females, younger age, early alcohol debut, and absence of parental drinking problem predicted higher level of prolactin. In males, presence of other substance dependence predicted a lower level of prolactin. Conclusions: There were gender differences in the factors associated with the level of prolactin among the AUD patients. Especially in the female AUD patients under remission, alcohol use trait-related factors were better predictors of the level of prolactin than the alcohol use state-related factors, indicating that individuals might characteristically have varying degree of dopamine reactivity

Antisocial Personality Disorder Among Patients in Treatment for Alcohol Use Disorder (AUD): Characteristics and Predictors of Early Relapse or Drop-Out

Background: Patients with alcohol use disorders (AUD) vary significantly in many clinically important characteristics making them a heterogenous group. AUD patients with comorbid antisocial personality disorder (ASPD) form an important sub-group, and studies indicate that these patients may have poorer treatment outcomes. Therefore, we aimed to investigate the characteristics of AUD inpatients with comorbid ASPD and identify predictors of early relapse or treatment drop-out in these patients. Methods: In a longitudinal study of AUD patients (n = 113; 30 females; aged 27 to 72 years) in treatment at three residential rehabilitation clinics in Norway, we used interviews and self-report questionnaires to collect data on alcohol use, mental health, and trauma experience. In addition, we assessed biochemical parameters. The patients were followed up at 6 weeks to identify early relapse or drop-out. Results: Prevalence of ASPD among AUD patients was 15%. AUD patients with comorbid ASPD were exclusively male, of younger age, and reported more childhood trauma, and adult attention-deficit-hyperactivity-disorder symptoms. They reported more hazardous drinking behavior and more often had dependence on substances in addition to alcohol. The presence of ASPD did not predict early relapse or drop-out. However, early relapse or drop-out in ASPD patients was associated with childhood and adult trauma, younger age of drinking debut, and higher baseline prolactin levels. Conclusion: AUD patients with ASPD had different clinical characteristics to other AUD patients and they had specific predictors of early relapse or drop-out. Our findings indicate that the early relapse or drop-out among AUD patients with ASPD may be attributed to environmental and possibly biological vulnerability. However, further studies with larger sample size are warranted to confirm these preliminary associations.

Depressive symptoms in the general population: The 7th Tromsø Study

Background: The prevalence of depressive symptoms may differ in various age groups. The aim of the study was to investigate the point-prevalence of depressive symptoms in the adult general population and in various age groups. The impact of sex, marital status, education, and social support on depressive symptoms was also explored. Methods: The population ≥40 years in the city of Tromsø, Norway, were invited to participate in the survey, of whom 64.7% (n=21,083) participated. All participants with a completed Hospital Anxiety and Depression Scale (HADS) were included in the study. A score ≥8 in the HADS depression subscale (HADS-D) was used to indicate caseness for depression. Results: The caseness for depression was 7.5% for men and 6.3% for women, overall 6.9%. The age groups 40-49 years and 80+ years had highest caseness. The overall HADS-D score for the total population was 2.8 (SD 2.7). The mean HADS-D for men (3.1; SD 2.8) was higher than for women (2.6; SD 2,6) (p<0.001). Low social support, low education and not living with a spouse was associated with higher risk for depressive symptoms. Limitations: The prevalence of depressive symptoms was based on a questionnaire, and represents only an estimate of depression in the population. Participants over 80 years were underrepresented, as fragile elderly and elderly living in nursing homes did not participate. Conclusions: Depressive symptoms were more prevalent in the youngest and oldest age groups. Participants reporting low social support, low education and not living with a spouse had higher risk for depressive symptoms

The Self-Rated Effects of Alcohol Are Related to Presystemic Metabolism of Alcohol

Aims - A high number of alcohol units required to feel a subjective effect of alcohol predicts future alcohol use disorders (AUDs). The subjective response to alcohol can be measured using the validated retrospective self-rated effects of alcohol (SRE) questionnaire. Few studies have investigated the specific relationship between SRE and blood alcohol concentration (BAC) in an experimental setting. Methods - Twenty healthy young adult male volunteers who had experience with binge drinking, but did not have AUD, filled out the SRE-questionnaire and were served with a fixed amount of alcohol per body weight. BACs were measured throughout a 12-hour period, reaching a maximum BAC of ~0.13%. Median split of SRE-scores was utilized to compare BACs among participants with relatively high effects (low SRE) and relatively low effects (high SRE) of alcohol. Results - Participants reporting a relatively low SRE-score had a statistically significant higher measured BAC at all time points until alcohol was eliminated. This was especially pronounced during the first 2 hours after alcohol (P = 0.015) without a significant difference in the alcohol elimination rate being detected. Conclusion - The study indicates that a self-ated SRE-score is related to BACs after the ingestion of a standardized amount of alcohol per body weight. Reporting a higher number of alcohol units before feeling an effect was related to a lower BAC. As the differences in BAC between relatively high and low self-rated effects appeared rapidly after intake, this could be interpreted as an effect of presystemic metabolism of alcohol

Trajectories of Service Contact before Suicide in People with Substance Use Disorders—A National Register Study

Objective: This study aimed to identify trajectories of service use during the last year before suicide death and the characteristics associated with the trajectories in patients with substance use disorders. Methods: This study used a national registry data linkage, which included all patients with substance use disorders who died by suicide in Norway between 2010 and 2018. In- and outpatient contacts with mental health or substance use services during the last year before suicide death was analyzed by week using Sequence State Analysis and cluster analysis to identify trajectories. Logistic regression was used to measure the association between the characteristics and the trajectories. Results: We identified four trajectories of service contact. A brief contact trajectory (n ¼ 366) with a low proportion of weeks in contact (M weeks ¼ 8.3), associated with less psychosis or bipolar disorder (aOR ¼ 0.13 (0.08–0.22)) and higher age. A regular contact trajectory (n ¼ 160), with a higher proportion of contact (M weeks ¼ 47.9), associated with psychosis or bipolar disorder (aOR ¼ 3.66 (2.10–6.47)) and depressive or anxiety disorder (aOR ¼ 3.11 (1.93–5.13)). An intermittent contact trajectory (n ¼ 195) with most contacts with outpatient substance use disorder services (M weeks ¼ 9.7). A continuous contact trajectory (n ¼ 109) with a high proportion of inpatient contact (M weeks ¼ 44.5), strongly associated with psychosis or bipolar disorder (aOR ¼ 6.08 (3.26–11.80)). Conclusion: Longitudinal descriptions of service use reveal different trajectories that are important to consider when developing policies or interventions to reduce the risk of suicide death in patients with substance use disorders

Mortality and alcohol-related morbidity in patients with delirium tremens, alcohol withdrawal state or alcohol dependence in Norway: A register-based prospective cohort study

Background and Aims: Little is known about long-term consequences of delirium tremens (DT). This study aimed to compare all-cause and cause-specific mortality and alcohol-related morbidity between patients with: (i) DT, (ii) alcohol withdrawal state (AWS) and (iii) alcohol dependence (AD). Design: A national longitudinal health registry study with linked data from the Norwegian Patient Registry and the Norwegian Cause of Death Registry. Setting: Norway. Participants: All patients registered in the Norwegian Patient Registry between 2009 and 2015 with a diagnosis of AD (ICD-10 code F10.2), AWS (F10.3) or DT (F10.4) and aged 20–79 years were included (n = 36 287). Measurements: Patients were categorized into three mutually exclusive groups; those with DT diagnosis were categorized as DT patients regardless of whether or not they had received another alcohol use disorder diagnosis during the observation period or not. Outcome measures were: annual mortality rate, standardized mortality ratios (SMR) for all-cause and cause-specific mortality and proportion of alcohol-related morbidities which were registered in the period from 2 years before to 1 year after the index diagnosis. Findings: DT patients had higher annual mortality rate (8.0%) than AWS (5.0%) and AD (3.6%) patients, respectively. DT patients had higher mortality [SMR = 9.8, 95% confidence interval (CI) = 8.9–10.7] than AD patients (SMR = 7.0, 95% CI = 6.8–7.2) and AWS patients (SMR = 7.8, 95% CI = 7.2–8.4). SMR was particularly elevated for unnatural causes of death, and more so for DT patients (SMR = 26.9, 95% CI = 21.7–33.4) than for AD patients (SMR = 15.2, 95% CI = 14.2–16.3) or AWS patients (SMR = 20.1, 95% CI = 16.9–23.9). For all comorbidities, we observed a higher proportion among DT patients than among AWS or AD patients (P < 0.001). Conclusions: People treated for delirium tremens appear to have higher rates of mortality and comorbidity than people with other alcohol use disorders

The temporal association between suicide and comorbid mental disorders in people treated for substance use disorders: a National registry study

Background The time after contact with specialized health services for mental health and substance use is associated with an increased risk of suicide, where temporal aspects of suicide and comorbid mental disorders in patients with substance use disorders could be associated. This study aimed to examine the temporal association between time from last treatment contact to suicide and comorbid mental disorders in patients with substance use disorders. Methods This study is a historical prospective case series using nationwide registry data. It included 946 individuals registered the year before suicide with a substance use disorder (F10-F19) in Norway’s specialized health services for treating substance use and mental health disorders between 2010 and 2020. The outcome was the number of weeks from the last contact with services to suicide. The exposure was comorbid mental disorders divided into ’no comorbid mental disorder’; ‘psychosis or bipolar disorders’ (F20−F31), ‘depressive or anxiety disorders’ (F32−F49); and ’personality disorders’ (F60-F69). Covariates included gender, age, last diagnosed substance use disorder, registered deliberate self-harm last year, and the number of in- and outpatient contacts the previous year. Results The number of weeks from last service contact to suicide difered (p= <0.001) between patients with no comorbid mental disorders (Median=7; IQR 2–23), psychosis or bipolar disorders (Median=2; IQR=1–7), depressive or anxiety disorders (Median=3; IQR=1–11) and personality disorders (Median=1; IQR=1–5.5). Signifcantly decreased adjusted incidence rate ratios (aIRR) were found for psychosis or bipolar disorders [aIRR=0.67 (95% CI 0.53–0.85)] and personality disorders [aIRR=0.56 (0.42–0.77)] compared to no comorbid mental disorder when adjusted for individual characteristics and service contact. For depressive and anxiety disorders compared to no comorbid mental disorder, the association was signifcant when adjusted for individual characteristics [aIRR=0.55 (0.46–0.66)]. Conclusions While patients with substance use disorders generally died by suicide a short time after contact with services, patients with comorbid mental disorders died an even shorter time after such contact and signifcantly shorter than patients without such comorbidities

Rusutløst psykose – en problematisk diagnose

Hvert år legges over 500 pasienter inn på norske sykehus med diagnosen rusutløst psykose. Men rusmiddelbruk er bare én av flere bidragende faktorer til at disse pasientene blir psykotiske, og mange får senere en schizofrenidiagnose
