About this study
Introduction: Cardiovascular diseases (CVD) are the main cause of death in Western countries. High levels of homocysteine (He) has been considered an important risk factor for coronary artery disease. Objective: To evaluate the effects of the drug Tenavit® (pyridoxine hydrochloride 4.00mg + folic acid 0.80mg + cyanocobalamin 0.40 mg) on plasma homocysteine concentrations and lipid profile in postmenopausal women. Methods: Sixty women were postmenopausal selected from the outpatient Gynecology Hospital Santa Marcelina that passed by routine consultations and fulfilling the inclusion criteria were invited to the study. The women were randomly allocated to control or experimental group (30 in each group) in a do uble-blind controlled clinical trial. The experimental group received one tablet of Tenavit® daily and the placebo group received the same tablet with the organoleptic characteristics of Tenavit® for a period of 4 months. The women were assessed before the intervention and after 4 months of medication. A self-report questionnaire to assess quality of life (QSF-36) was applied and anthropometric measurements, cholesterol and fractions, triglycerides, fasting glucose, homocysteine and cysteine were evaluated. Results: The only variable that presented significant alteration in both dimensions (between and within group) was the homocysteine. It was observed statistical significant between groups in the final measure for homocysteine (control group: 11.5mmol/ L; experimental group: 9.4 mmo
Read the detailed description
Subjects The study protocol and informed consent was approved by the Ethics Committee of the Hospital Santa Marcelina, Sao Paulo, Brazil (Process nº 09/08, CAAE nº 0016.0.270.000-08).Sixty women (figure 1) were postmenopausal selected from the outpatient Gynecology - Endocrine Hospital Santa Marcelina that passed by routine consultations and fulfilling the inclusion criteria were invited to the study.
Inclusion criteria were: a year of amenorrhea, FSH (follicle stimulating hormone) greater than 30mUI/ml and submit dyslipidemia, defined as LDL> 150 mg / dl15. Women with diabetes difficult to control or with recent myocardial infarction or thromboembolic diseases, severe hepatic impairment or activity were excluded. In addition, patients who had any form of cancer were excluded from the group.
Study Design The women were randomly allocated to control or experimental group (30 in each group) in a double-blind controlled clinical trial. The experimental group received one tablet of Tenavit®(pyridoxine hydrochloride 4.00mg + folic acid 0.80mg + cyanocobalamin 0.40mg) daily and the placebo group received the same tablet with the organoleptic characteristics of Tenavit® for a period of 4 months. After this period of treatment, the women were assessed.
Procedures During clinical examination, a self-report questionnaire to assess quality of life (QSF-36) that demonstrates how the individual feels regarding your activities, your health and disposition on a daily, always referring to the last month15, was applied. The Framingham Score was also applied. Framingham predictions was good in the low- to intermediate cardiovascular risk16,17.Anthropometric measurements of blood pressure, weight, height, body mass index, waist and hip were evaluated by the same medical team. Venous blood was collected on two different occasions during the study (at baseline and at end of treatment), while maintaining the 12-hour fast and the interval of 4 months between tests, both in the experimental and in the control group. Total cholesterol and fractions, triglycerides, fasting glucose, homocysteine and cysteine were performed. The dosage of plasma homocysteine and cysteine was performed by high performance liquid chromatography (HPLC).

What is being measured
The primary outcome is the main question the study is designed to answer.
supplementation may be beneficial in postmenopausal patients, with the intention to reduce the level of homocysteine
supplementation may be beneficial in postmenopausal patients, with the intention to reduce the level of homocysteine and, thus, reduce the cardiovascular risk in this age.
Measured: The women were assessed before the intervention and after 4 months of medication.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Tenavit® in people with Menopause and Dyslipidemias, run by Casa de Saúde santa Marcelina.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 21 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
supplementation may be beneficial in postmenopausal patients, with the intention to reduce the level of homocysteine (time frame: The women were assessed before the intervention and after 4 months of medication.). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03221816, which also lists 12 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Jul 2017.
