Brief Summary:

To evaluate the effectiveness of an algorithm for Bipolar Disorder depressive episodes (BDD) using medications available in the Brazilian Public Healthcare System (SUS). Quality of life assessment of these patients was also employed.

A randomized pragmatic trial was conducted. An algorithm was developed for the treatment of episodes of bipolar disorder depression episodes.


Condition or disease Intervention/treatment Phase
Bipolar Disorder Drug: Lithium Carbonate Drug: Sertraline Drug: Nortriptyline Drug: Risperidone Phase 4

Detailed Description:

The study design was that of a pragmatic randomized clinical trial to evaluate the effectiveness of treatments for mood disorders in a public healthcare context in the city of Porto Alegre, in southern Brazil. The algorithm was originally developed for the treatment of bipolar disorder depressive episodes by a Delphi panel of experts from psychiatric associations in Brazil. All subjects provided an informed consent form, in writing, in order to participate in the study protocol, which was approved by the institutional ethics committee.

Procedures and measurements of the study:

The subjects under evaluation were selected and they followed the stages defined by the treatment protocol:

  1. Sample selection by being referred from the primary healthcare clinics in the municipality;
  2. Informative talk about mood disorders and the research, with the informed consent forms being provided to the subjects;
  3. Screening for unipolar depression episodes with the use of the Patient Health Questionnaire (PHQ-9), and Hypomanic Symptoms Checklist Brazilian Version (HCL -32-BV);
  4. Diagnostic evaluation through the Mini International Neuropsychiatric Interview (MINI) and clinical interview for individuals with positive results in the screening instruments;
  5. Baseline and demographic assessments using standardized semi-structured interviews in the first and second visits;
  6. In each clinic visit, the severity of the symptoms were evealuated using the Clinical Global Impression Scale (CGI), Hamilton Rating Scale for Depression (HRSD), and Young Manic Rating Scale (YMRS);
  7. Biweekly follow-up, changed to monthly after stabilization - with a maximum follow-up period of 52 weeks.

Arm Intervention/treatment
Experimental: Lithium

Group Started: Lithium (900mg-1500mg)

Subjects evaluated for responsiveness every 2 weeks. Responsive to treatment patients remain in the same step. Max. step duration of 8 weeks.

First step: Monotherapy with Lithium (LSL 0.6-0.8). Non responsive patients: 2nd step.

Second step: Monotherapy with lithium (LSL 1.0-1.2). Non responsive patients: 3rd step.

Third step: Lithium + Sertraline (50mg-200mg). Non responsive patients: 4th step.

Fourth step: Lithium + Nortriptyline 100mg. Non responsive patients: 5th step.

Fifth step: Lithium + Nortriptyline 100mg + Sertraline (100mg-200mg). Non responsive patients: 6th step

Sixth step: Lithium + Nortriptyline 100mg + Sertraline 200mg + Risperidone (1mg-6mg).

Drug: Lithium Carbonate
Other Name: Carbolitium

Drug: Sertraline
Other Name: Zoloft

Drug: Nortriptyline
Other Name: Pamelor

Drug: Risperidone
Other Name: Risperdal




Primary Outcome Measures :
  1. Response to treatment [ Time Frame: 8 weeks ]
    Response to treatment was defined as a 50% reduction from baseline in HRSD and YMRS scales.


Secondary Outcome Measures :
  1. Remission [ Time Frame: 8 months ]
    The remission outcome was established as obtaining three consecutive scores of values considered asymptomatic (HRSD <7 points, and YMRS <6 points). The subjects that were asymptomatic for at least 6-8 month were considered to be in remission, according to the criteria for partial and complete remission in the DSM-IV.

  2. Quality of life [ Time Frame: 12 weeks ]
    QOL scores as measured by World Heath Organization Quality of Life - WHOQOL -BREF instrument.
