Co je měření studie?

Primární výstupní opatření

Měření výsledku
The main objective of this study is to compare the efficacy in the prevention of relapse to manic, depressive, or
mixed episodes in two groups of bipolar I patients
who responded to open-label treatment with olanzapine in mono or co-therapy and who are in symptomatic and syndromic remission at the time of entering the study.
The first group will receive olanzapine for a period of
3 months following inclusion into the study; the second group will receive olanzapine for 12 months.
Relapses will be evaluated in terms of the total YMRS
(Young Mania Rating Scale) and HAMD-21 (the 21-item Hamilton Depression Rating Scale) scores.

Sekundární výstupní opatření

Měření výsledku
The secondary objectives posed by this study are the following:
To compare the efficacy of maintaining olanzapine for 3 months versus maintaining it for 12 months in
the improvement of symptomatology in patients who had achieved remission. To this end, the reductions
on the total YMRS score, YMRS specific non-psychotic
item scores, HAMD 21 total score, the scores on the
HAMD 21 specific mood-related items, the total and
positive scores on the BPRS (Brief Psychiatric Rating Scale), and the CGI BP S(Clinical Global Impression of Severity) with respect to baseline will be evaluated.
DSM IV TR criteria will be used for manic and
depressive episodes in order to assess syndromic improvement.
To compare the efficacy of long-term treatments by means of longitudinal assessment using the
general subscale of the CGI BP M (Clinical Global Impression - Modified) and proceeding to
intra- and intergroup analyses.
To evaluate the safety of maintenance treatment
with olanzapine and other coadjuvant medication
in both groups of follow up. To collect data
regarding treatment-derived adverse events,
changes in vital signs, laboratory analyses, and to measure the severity of possible extrapyramidal symptoms.
The Simpson Angus Scale, Barnes Akathisia Scale, and the Abnormal Involuntary Movement Scale (AIMS) will be used to assess the latter.
To determine the impact on resource utilization
the two treatment groups have. Direct costs derived
from hospital admissions, emergency room visits,
out-patient visits, home healthcare supports, as well as indirect costs derived from days out of work,
the patient's economic income, impact on the caregiver will also be quantified.
To assess the differences between groups
with respect to improvement in functioning and quality of life. The SF 36 Scale (the 36-Item Social Function Scale) will be applied.
To understand the degree of impact the illness provokes in relatives or caregivers
throughout the study. The self-report scale of
family burden (Escala de Carga Familiar - ECF) will be used for this purpose.
