Independent predictors for lifetime and recent substance use disorders in patients with rapid-cycling bipolar disorder: focus on anxiety disorders.

We set out to study independent predictor(s) for lifetime and recent substance use disorders (SUDs) in patients with rapid-cycling bipolar disorder (RCBD). Extensive Clinical Interview and Mini-International Neuropsychiatric Interview were used to ascertain DSM-IV Axis I diagnoses of RCBD, anxiety disorders, and SUDs. Data from patients enrolling into four similar clinical trials were used.

A 6-month, double-blind, maintenance trial of lithium monotherapy versus the combination of lithium and divalproex for rapid-cycling bipolar disorder and Co-occurring substance abuse or dependence.

Objective: To assess whether combination treatment with lithium and divalproex is more effective than lithium monotherapy in prolonging the time to mood episode recurrence in patients with rapid-cycling bipolar disorder and comorbid substance abuse and/or dependence.

Method: A 6-month, double-blind, parallel-group comparison was carried out in patients who met DSM-IV criteria for (1) bipolar I or II disorder; (2) alcohol, cannabis, or cocaine abuse within the last 3 months or dependence within the last 6 months; (3) rapid cycling during the 12 months preceding study entry; and (4) a history of at least 1 manic, hypomanic, or mixed episode within 3 months of study entry and who had demonstrated a persistent bimodal response to combined treatment with lithium and divalproex. Subjects were randomly assigned to remain on combination treatment or to discontinue divalproex and remain on lithium monotherapy.

Medical and substance use comorbidity in bipolar disorder.

Objective: National Comorbidity Survey data indicate that bipolar disorder is characterized by high lifetime rates of co-occurring anxiety and substance use disorders (SUDs). Although compelling evidence suggests SUD comorbidity predicts non-response to treatment, the relationship between medical comorbidity and treatment response has not been studied adequately. In an attempt to understand the impact of medical comorbidity on treatment outcome, an analysis was conducted to inform the relationship between co-occurring medical illness, the phenomenology of bipolar disorder, and response to treatment with mood stabilizers.

Clinical correlates of patients with rapid-cycling bipolar disorder and a recent history of substance use disorder: a subtype comparison from baseline data of 2 randomized, placebo-controlled trials.

Objective: To compare clinical variables in patients with rapid-cycling bipolar I or II disorder and a recent history of substance use disorder (SUD).

Method: Cross-sectional data from 2 studies of patients with rapid-cycling bipolar I disorder or rapid-cycling bipolar II disorder and a recent history of SUD were used to retrospectively assess the differences in clinical variables between the subtypes. The studies were conducted from November 1997 to February 2007 at University Hospitals Case Medical Center, Case Western Reserve University School of Medicine, Cleveland, Ohio.

Differential interactions between comorbid anxiety disorders and substance use disorder in rapid cycling bipolar I or II disorder.

Objective: Anxiety disorders (AD) and substance use disorders (SUD) commonly co-occur with bipolar disorder. This study was undertaken to assess AD-SUD-bipolar subtype interactions.

Methods: Extensive clinical interview and MINI were used to ascertain DSM-IV diagnoses of rapid cycling bipolar I (RCBPDI) or II (RCBPDII) disorder, SUDs, and ADs including generalized anxiety disorder (GAD), panic disorder (PD), and obsessive-compulsive disorder (OCD).

Screening for bipolar disorder in a county jail at the time of criminal arrest.

Objective: This study assessed the operating characteristics of the mood disorder questionnaire (MDQ) among offenders arrested and detained at a county jail.

Method: The MDQ, a brief self-report instrument designed to screen for all subtypes of bipolar disorder (BP I, II and NOS) was voluntarily administered to adult detainees at the Ottawa County Jail in Port Clinton, Ohio. A confirmatory diagnostic evaluation was also performed using the mini-international neuropsychiatric interview (MINI).

A 20-month, double-blind, maintenance trial of lithium versus divalproex in rapid-cycling bipolar disorder.

Objective: The authors tested the hypothesis that divalproex would be more effective than lithium in the long-term management of patients with recently stabilized rapid-cycling bipolar disorder.

Method: A 20-month, double-blind, parallel-group comparison was carried out in recently hypomanic/manic patients who had experienced a persistent bimodal response to combined treatment with lithium and divalproex. Sixty patients were randomly assigned to lithium or divalproex monotherapy in a balanced design after stratification for illness type (bipolar I versus bipolar II disorder).

Gender differences in criminality: bipolar disorder with co-occurring substance abuse.

Outpatient interviews to collect criminal history data were conducted with 55 women and 77 men who had the dual diagnosis of rapid-cycling bipolar disorder with co-morbid substance abuse disorders (DD-RCBD), to ascertain gender-related similarities and differences. Fifty-three percent of women and 79 percent of men reported that they had been charged with a crime, and nearly half of those charged had been incarcerated. Men with DD-RCBD were more likely to have committed a felony and had a trend of committing more misdemeanors.
