Detailed Description
This research aims to verify in a pilot study the effect of selenium as an augmentation treatment for sertraline-resistant major depression and, as secondary endpoints, if the levels of selenium in patients with depressive episodes are different from individuals without depression. Thus, this clinical trial was intended to be a randomized double-blind placebo-controlled clinical trial evaluating the effect of selenium or placebo in patients diagnosed with major depression who have not responded to treatment with sertraline in appropriate dose and treatment duration. The initial sample will be comprised of patients with moderate or severe major depression, who will receive sertraline up to 200mg/day, for at least 8 weeks. A group of subjects without major depression will be selected as a control sample, which will be submitted to the same procedures of the included patients. It is estimated an initial sample of 90 patients with major depression (DSM-IV criteria), and about 30 patients resistant to treatment, which will be randomly divided into two groups (selenium and placebo). The control group sample is estimated to be 45 subjects.
For the diagnosis of major depression, it will be used the Structured Clinical Interview for DSM Axis I disorders (SCID Structured Clinical Interview for the DSM-IV Axis I disorders). To evaluate the outcome of treatment of the depressive symptoms, it will be used the Clinical Global Impression Scale and Patient Global Impression Scale (CGI and PGI), Hamilton Depression Rating Scale of 17 items for depression (HAM-D-17), Montgomery-Asberg Depression Rating Scale (MADRS) and SAFTEE- (brief structured interview assessing adverse events). The exclusion criteria include patients with any diagnosis of psychosis, bipolar disorder, personality disorder, any psychiatric condition that need hospitalization, severe risk of suicide, recent drug abuse or dependence, use of any polyvitamin substance, or any substance with known relevant psychopharmacological action, women with known or suspected pregnancy or breastfeeding, and people with unstable organic disease such as lupus erythematosus, uncontrolled diabetes mellitus, hypothyroidism and hyperthyroidism.
Participation is voluntary, and participants of both genders must be over the age of 18 years. After checking for exclusion and inclusion criteria (visit 0), the first phase of the study will start with the completion of the following laboratory tests: serum levels of selenium, electrocardiogram, hematology (hemoglobin, hematocrit, white blood cell count, platelet count), SGOT, SGPT, gammaGT, urea, creatinine, fasting glucose, TSH, free T4, T3, Na, K, total cholesterol + triglycerides fractions, urine analysis.
The second phase consists in the treatment of patients with depression with sertraline, which will receive initial dosage of 50 mg / day up to 200 mg or maximum tolerated dose, according to the investigator's decision, for at least 8 weeks. Patients considered resistant-sertraline (Hamilton-D-17> 7) will be invited to participate in the double-blind randomization phase to treatment groups with placebo or selenium (400 mcg / day). Sertraline will be maintained throughout the whole phase randomization. As the trial would be completed, participants will be referred to outpatient care in community health services. Initially the variables will be analyzed descriptively. In phase 1 Student's test will be used in order to compare the serum levels of selenium in both groups. At stage 2 for comparison of pre and post treatment with Sertraline it will be used the non-parametric McNemar test and in step 3, to determine the behavior of the groups during six weeks, it will be used analysis of variance with repeated measures.

Description
Inclusion Criteria:
- of both genders
- over the age of 18 years
- in outpatient care
- who meet the diagnostic criteria for major depression by the DSM-IV, confirmed by the application of structured interview SCID,
- with scores higher than 17 on the Hamilton scale of 17 items for depression
- who agree to participate voluntarily in the study, after full and unrestricted information about the study to be performed, as documented by signing the informed consent
- Women of childbearing age need negative pregnancy test in the pre-assessment tests, and must use prevention of pregnancy during treatment.
Exclusion Criteria:
- have a known sensitivity to sertraline or selenium
- have psychiatric hospitalization indication, due to the presence of any psychiatric condition that would justify the hospitalization, including patients with severe risk of suicide.
- have history of resistance to sertraline treatment, in clinical effective doses and for appropriate duration (at least 100 mg for at least 8 weeks).
- have any psychosis (including diagnostic ICD10 F20-29, F06.0-06.2, F32.3 and F33.3), bipolar disorder or personality disorder
- have received regular medication with psychotropic action the week prior to the trial inclusion
- have received fluoxetine in the last four weeks prior to trial inclusion
- have used any substance considered as a polyvitamin the week prior the inclusion
- have received monoamine oxidase inhibitors 14 days prior to selection
- show clinical diseases that require the use of medications that can interact with sertraline.
- known or suspected pregnancy.
- breast-feeding women.
- Use of any drug that has known and relevant psychopharmacological action, despite not having preferential psychotropic drug use, unless it has been used with a stable dose for at least a month.
- have dependency on any psychoactive substance in the last 12 months (except caffeine and tobacco).
- Presence of an unstable disease that compromises the outcome (eg. Lupus Erythematosus, decompensated diabetes mellitus, cardiac insufficiency) that will determined clinically by the investigator.
For the control group, the same criteria of inclusion and exclusion above will be applied, except for the diagnosis of major depression by the DSM-IV and the scores of the Hamilton rating scale for depression.
