Is impaired outcome following a first manic episode due to mood-incongruent psychosis?

BACKGROUND: Mood-incongruent psychosis during the course of bipolar disorder has been associated with poor outcome. However, it remains unknown whether this is secondary to persistent affective or psychotic symptoms or both. METHOD: Fifty patients with bipolar disorder between the ages of 16 and 45 years were recruited during their first psychiatric hospitalization for mania. These patients were evaluated using structured and semi-structured clinical instruments then followed longitudinally. Outcomes during the first eight months of follow-up were compared between patients with mood-incongruent psychosis and those without (i.e., patients with mood-congruent psychosis or no psychosis) during the index manic episode. Specifically, ratings of the percent of weeks during follow-up with psychosis and affective syndromes and symptoms, as well as ratings of global outcome (GAF), were compared. RESULTS: Patients with mood-incongruent psychosis at the index hospitalization exhibited significantly more weeks during follow-up with both mood-incongruent and mood-congruent psychotic symptoms than patients without mood-incongruent psychosis. Mood-incongruent psychosis was also associated with poorer overall functioning during the outcome interval. The groups did not differ in the percent of weeks with affective syndromes or symptoms. Treatment during follow-up did not differ between groups and was not associated with outcome variables in general. CONCLUSION: Mood-incongruent psychosis that occurs during the first manic episode appears to predict an increased likelihood of persistent psychotic symptoms during the subsequent eight months. This persistence of psychosis is associated with a worse overall course of illness as compared to patients without mood-incongruent psychosis. LIMITATIONS: These results apply to a relatively short outcome period and are from a single center.

12-month outcome of patients with bipolar disorder following hospitalization for a manic or mixed episode.

OBJECTIVE: The authors studied the 12-month course of illness following hospitalization for a manic or mixed episode of bipolar disorder to identify potential outcome predictors. METHOD: They recruited 134 patients with DSM-III-R bipolar disorder who were consecutively admitted for the treatment of a manic or mixed episode. Diagnostic, symptomatic, and functional evaluations were obtained at the index hospitalization. Patients were reevaluated at 2, 6, and 12 months after discharge to assess syndromic, symptomatic, and functional outcome. Factors associated with outcome were identified by using multivariate analyses. RESULTS: During the 12-month follow-up period, there were no significant differences in outcome between patients with manic compared with mixed bipolar disorder. Although syndromic recovery occurred in 48% of the overall group, symptomatic recovery occurred in only 26% and functional recovery in only 24%. Predictors of syndromic recovery included shorter duration of illness and full treatment compliance. Medication treatment compliance was inversely associated with the presence of comorbid substance use disorders. Symptomatic and functional recovery occurred more rapidly and in a greater percentage of patients from higher social classes. CONCLUSIONS: A minority of patients with bipolar disorder achieved a favorable outcome in the year following hospitalization for a manic or mixed episode. Shorter duration of illness, higher social class, and treatment compliance were associated with higher rates of recovery and more rapid recovery.

Twelve-month outcome after a first hospitalization for affective psychosis.

BACKGROUND: We studied the 12-month course of illness after a first hospitalization for affective psychosis to identify potential outcome predictors in this rarely studied patient population. METHODS: For this study, 109 patients consecutively admitted for their first psychiatric hospitalization for treatment of affective psychosis were recruited. Diagnostic, symptomatic, and functional evaluations were obtained at the index hospitalization and at 2, 6, and 12 months after discharge to assess syndromic, symptomatic, and functional outcome predictors. Factors associated with outcome were identified by means of multivariate analyses. RESULTS: Fifty-six percent of the patients achieved syndromic recovery during the 12-month follow-up. Full treatment compliance was associated with more frequent and rapid syndromic recovery. Full compliance was more common in white patients and in patients without substance abuse. Only 35% of these patients achieved symptomatic recovery during this same 12-month interval, and, similarly, only 35% achieved functional recovery. Symptomatic recovery was delayed in patients with substance abuse and was associated with higher socioeconomic status. Higher socioeconomic status was also associated with functional recovery, as was good premorbid function. CONCLUSIONS: Few patients achieved a favorable outcome in the year after a first hospitalization for an affective psychosis. Low socioeconomic status, poor premorbid function, treatment noncompliance, and substance abuse were associated with lower rates or delayed onset of recovery.

The effects of race and information variance on disagreement between psychiatric emergency service and research diagnoses in first-episode psychosis.

BACKGROUND: Previously, we reported that patient race was associated with disagreement between research and clinical diagnoses. To extend this work, we studied whether disagreement was specifically due to associations of patient race with information or criterion variance. METHOD: Ninety-nine patients consecutively admitted through the University of Cincinnati Psychiatric Emergency Service (PES) for a first hospitalization for psychosis were evaluated using the Structured Clinical Interview for DSM-III-R. Diagnoses made in the PES were compared with those obtained from the structured interview. We examined the contributions of information variance and criterion variance to the association between race and diagnostic agreement of PES and research diagnoses. RESULTS: Agreement in PES and research diagnoses was present in only 42% of patients. Diagnostic agreement was less common in non-white patients than white patients, even after controlling for other sociodemographic and clinical variables. Information variance was the cause of diagnostic disagreement in 58% of cases and was associated with patient race. Criterion variance, occurring in 42% of cases, was not associated with race. CONCLUSION: Patient race may contribute to the diagnostic process in the psychiatric emergency service by influencing the information obtained from patients during clinical evaluations.

Comparison of patients with early-, typical-, and late-onset affective psychosis.

OBJECTIVE: The authors compared the clinical characteristics and family history of patients with early-onset (before age 18), typical-onset (at 20-25 years), and late-onset (after age 35) affective psychosis at the time of first hospitalization. METHOD: Diagnostic, symptom, and family history information was obtained from 88 consecutively hospitalized patients. RESULTS: Major depression was more common in the late-onset group, and a family history of affective and substance abuse disorders was more common among the early-onset patients. Affective symptoms differed significantly among groups; specifically, early-onset patients had more energy, minimal sleep disruption, and greater suicidality, while typical-onset patients had more severe abnormal thought content. CONCLUSIONS: Among patients with affective psychosis, there may be heterogeneity of symptoms and family history associated with age at first hospitalization.

Compliance with maintenance treatment in bipolar disorder.

Studies of compliance with pharmacologic treatment in patients with bipolar disorder have primarily involved outpatients receiving lithium. To date, very little data addresses the rates of noncompliance in patients with bipolar disorder treated with other available mood stabilizers (e.g. divalproex, carbamazepine). One hundred and forty patients initially hospitalized for a bipolar disorder, manic or mixed episode, were evaluated prospectively over 1 year to assess their compliance with pharmacotherapy. Compliance was assessed by a clinician-administered questionnaire, using information from the patient, treaters, and significant others. Seventy-one patients (51%) were partially or totally noncompliant with pharmacologic treatment during the 1-year followup period. Noncompliance was significantly associated with the presence of a comorbid substance use disorder. Denial of need was the most common reason cited for noncompliance. Compliance was associated with being male and Caucasian and with treatment with combined lithium and divalproex or with this combination and an antipsychotic. Noncompliance with pharmacotherapy remains a substantial problem in the treatment of patients with bipolar disorder.
