Depression and severity of substance dependence among heroin dependent patients with ADHD symptoms.

BACKGROUND AND OBJECTIVES: Comorbid attention deficit hyperactivity disorder (ADHD) symptoms are highly prevalent among heroin-dependent patients. We aim to investigate differences in dependence severity, depression, and quality of life between heroin-dependent patients with and without ADHD-screened positive. METHODS: Heroin-dependent participants (n = 447) entering methadone maintenance treatment were divided into ADHD-screened positive (ADHD-P) and ADHD-screened negative (ADHD-N) groups according to scores of Adult ADHD Self-Report Scale (ASRS). Mini-International Neuropsychiatric Interview was used to identify current and lifetime depressive episodes and suicidality. Substance use disorder, depression, family support, and quality of life in two groups were also assessed. RESULTS: About 7.8% (n = 35) scored 24 or higher of ASRS indicating highly likely Adult ADHD. More heroin-dependent patients of ADHD-P had a current depressive episode (p = .02). They had higher Center for Epidemiological Studies Depression (CESD) scores (p = .003), and more severe heroin dependence (p = .006). Poorer family support and quality of life in physical, and psychological domains were found in patients of ADHD-P compared to ADHD-N. DISCUSSION AND CONCLUSIONS: Heroin-dependent patients of ADHD-P represent a vulnerable minority. They were comorbid with regard to depression, greater substance dependence severity, and poorer quality of life. SCIENTIFIC SIGNIFICANCE: Assessment for ADHD symptoms in heroin-dependent patients may be indicated for the effective management of the complex problems of these patients.

Increased risk of major depression subsequent to a first-attack and non-infection caused urticaria in adolescence: a nationwide population-based study.

BACKGROUND: Non-infection caused urticaria is a common ailment in adolescents. Its symptoms (e.g., unusual rash appearance, limitation of daily activities, and recurrent itching) may contribute to the development of depressive stress in adolescents; the potential link has not been well studied. This study aimed to investigate the risk of major depression after a first-attack and non-infection caused urticaria. METHODS: This study used the Taiwan Longitudinal Health Insurance Database. A total of 5,755 adolescents hospitalized for a first-attack and non-infection caused urticaria from 2005 to 2009 were recruited as the study group, together with 17,265 matched non-urticarial enrollees who comprised the control group. Patients who had any history of urticaria or depression prior to the evaluation period were excluded. Each patient was followed for one year to identify the occurrence of depression. Cox proportional hazards models were generated to compute the risk of major depression, adjusting for the subjects' sociodemographic characteristics. Depression-free survival curves were also analyzed. RESULTS: Thirty-four (0.6%) adolescents with non-infection caused urticaria and 59 (0.3%) non-urticarial control subjects suffered a new-onset episode of major depression during the study period. The stratified Cox proportional analysis showed that the crude hazard ratio (HR) of depression among adolescents with urticaria was 1.73 times (95% CI, 1.13-2.64) than that of the control subjects without urticaria. Moreover, the HR were higher in physical (HR: 3.39, 95% CI 2.77-11.52) and allergy chronic urticaria (HR: 2.43, 95% CI 3.18-9.78). CONCLUSION: Individuals who have a non-infection caused urticaria during adolescence are at a higher risk of developing major depression.
