Assessment of mood states in patients receiving long-term corticosteroid therapy and in controls with patient-rated and clinician-rated scales.

BACKGROUND Corticosteroids have been used for many years for inflammatory diseases. Mood changes are common during short-term, high-dose, corticosteroid therapy. Virtually no data are available on the mood effects of long-term corticosteroid therapy. OBJECTIVE To evaluate mood during corticosteroid therapy using standard clinician-rated and patient-rated measures. METHODS Outpatients receiving prednisone therapy (7.5 mg/d for 6 months) and similar controls were enrolled. Current mood was evaluated using the Hamilton Rating Scale for Depression (HRSD), Young Mania Rating Scale (YMRS), Brief Psychiatric Rating Scale (BPRS), Internal State Scale (ISS), and a diagnostic interview. RESULTS Twenty patients and 14 controls were enrolled in the study. Depressive symptom severity as evaluated by the HRSD and ISS depression and well-being subscales and global psychiatric symptom severity as evaluated by the BPRS and ISS perceived conflict subscale were greater in patients receiving prednisone than controls. Manic symptom severity as evaluated by the ISS activation subscale but not the YMRS was higher in patients receiving prednisone. Twelve (60%) of 20 corticosteroid-treated patients met diagnostic criteria for a lifetime prednisone-induced mood disorder. Activation subscale scores did not correlate with YMRS scores. Other ISS subscales showed expected correlations with clinician-rated assessments. CONCLUSIONS Mood symptoms and disorders are common in corticosteroid-dependent patients. Unlike short-term prednisone therapy, long-term therapy may be more associated with depressive than manic symptoms based on the clinician-rated assessments. The ISS may be more sensitive to mood symptoms with prednisone than clinician-rated scales.

Drug dreams in outpatients with bipolar disorder and cocaine dependence.

Patients with substance abuse or dependence often have dreams about alcohol or drugs during early recovery. However, the literature on drug dreams in rehabilitating patients with drug-related disorders remains limited. No data are available on drug dreams in people with substance-related disorders and other major mental illness. As part of a large study on the use of lamotrigine in patients with bipolar disorder and cocaine dependence, the frequency and nature of drug dreams, triggers for dreams, and response to the dreams during study participation were assessed in 37 outpatients for as long as 36 weeks. Altogether, 74% of participants experienced at least one drug dream during the study. Furthermore, drug dreams rapidly decreased during study participation. The presence of drug dreams at baseline did not predict mood, cocaine craving, or drug use at exit. No clear risk factors for drug dreams were identified. However, drug dreams were related to survival in the study by a negative U-shaped curve relationship in which those participants with the highest and lowest frequency of drug dreams discontinued from the study the earliest. Content of the dreams frequently included drug use or refusing to use the drug. Dreams of drug use tended to occur during the first few weeks of study participation. Most dreams were associated with triggers for drug use. The findings suggest that drug dreams are common in patients with bipolar disorder and cocaine dependence and are similar in nature to those previously reported in people with pure substance abuse.

Impulsivity in patients with bipolar disorder and cocaine or amphetamine dependence given lamotrigine

ABSTRACT Objective: Impulsivity is a component of bipolar disorder, substance-related disorders, and antisocial personality disorder. Method: Barratt Impulsiveness Scale nonplanning subscale (BIS-11-NP) scores were assessed from 2001–2003 in 37 outpatients in Dallas, Texas with bipolar disorder and cocaine or amphetamine dependence during therapy with lamotrigine. Results: Baseline BIS-11-NP scores correlated positively with baseline suicidality. BIS-11-NP scores decreased significantly from baseline to exit. Baseline to exit change on the BIS-11-NP correlated with change in some psychiatric symptom measures, drug craving, and days of drug use. A limitation of the study is the small sample size. Conclusion: The results suggest that lamotrigine is associated with decreased impulsivity.

Comparison of the Internal State Scale to Clinician-Administered Assessments in Patients with Bipolar Disorder and Alcohol Abuse or Dependence

Abstract Objectives: Self-report measures require less clinician time to administer than clinician-rated assessments. The Internal State Scale (ISS) is a well-validated self-report measure that assesses symptoms of mania and depression in patients with bipolar disorder (BPD). However, the ISS has never been specifically evaluated in patients with BPD and comorbid substance misuse. Substances can induce mood symptoms complicating diagnosis and mood state assessment. Methods: The ISS was compared with the Hamilton Rating Scale for Depression (HRSD), Young Mania Rating Scale (YMRS), and Brief Psychiatric Rating Scale (BPRS) in 21 patients with BPD and alcohol abuse/dependence at baseline and for up to 16 weeks postbaseline. In addition, ISS-determined mood state was compared to mood state from a structured diagnostic interview. Results: Significant baseline correlations were observed between the ISS depression subscale and HRSD, ISS activation subscale and YMRS, and ISS perceived conflict subscale and BPRS. Significant correlations of baseline to exit change scores were found between the ISS activation and YMRS, but not ISS depression and HRSD, or ISS perceived conflict and BPRS. All participants had a mixed mood state by structured diagnostic interview. The ISS diagnosed the manic/hypomanic portion of this mood state in 76% of participants but found depression in only 38%. Conclusions: As in BPD patients without substance abuse, the ISS generally showed correlations with clinician-rated scales at baseline, with less strong correlations observed on change scores. The ISS diagnosis of mania or hypomania appeared to correspond more highly than depression with the findings from a structured diagnostic interview.
