To Identify and Evaluate the Predictive Factors for Depression in Patients Diagnosed With Multiple Sclerosis

July 30, 2014 updated by: Merck KGaA, Darmstadt, Germany

Predicting Factors for Depression in Patients With MS in Argentina

This is an observational, non controlled, multicentric, prospective study planned to be conducted in 350 subjects diagnosed with multiple sclerosis (MS) in 20 centres of Argentina to identify the predictive factors leading to depression. The incidence of depression symptoms and its influence in the evolution of the disease are unknown in the Argentinean population. Early diagnosis of depression symptoms allows the specific treatment of them and can also delay the rich apparition of the disease. This study intends to quantify the incidence of these symptoms and also aims to evaluate which are the predictive factors of the apparition of the depression.

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

Multiple sclerosis is a chronic, demyelinating disease of the central nervous system and is considered to be one of the most common cause of neurological disability in young adults. The clinical and pathophysiological characteristics of the disease lead to the association of several conditions over time, among which the depression and/or the depression symptoms are one of the most important ones. The underlying mechanism of depression is not clear and the etiology of depression is considered to be multifactorial and especially associated to the psychosocial stress, to the presence of focal demyelinating lesions and to the immune malfunction. Several scales like Beck Depression Inventory Fast Screen (BDI FS), Mini Mental State Examination (MMSE), Hamilton Depression Rating Scale (HDRS) have been used to objectify the presence of depression symptoms in subjects with MS.

OBJECTIVES

Primary objective:

  • Identification of the predictive factors for the development of depression symptoms in subjects with MS in Argentina

Secondary objective:

  • Evaluation of the proportion of subjects that develop depression symptoms during the follow up

The subjects will be managed with the clinical and therapeutic elements that the treating doctors considered appropriate, without modifying their decisions due to the subjects' inclusion into the study.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Subjects with diagnosed MS in Argentinean population.

Description

Inclusion Criteria:

  • Subjects aged between 18 65 years of both sexes
  • Subjects with established MS diagnosis according to the revised Mc Donald criteria - 2005 in any of its clinical forms
  • Subjects with signed informed consent
  • Subjects wiling to follow the study procedure

Exclusion Criteria:

  • Subjects with diagnosis of depression at the moment of the initial evaluation
  • Subjects receiving antidepressant drugs at the moment of the initial evaluation
  • Subjects with moderate or severe cognitive impairment

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Apparition and/or modification of depression symptoms through the agreed assessments
Time Frame: Each visit starting from the initial visit (Day 0) to end of the observation period (i.e. 24 months)
The assessments will include Expanded Disability Status Scale, Hamilton Depression Rating Scale, Mini Mental State Examination, Beck Depression Inventory, clock drawing test and findings in magnetic resonance imaging.
Each visit starting from the initial visit (Day 0) to end of the observation period (i.e. 24 months)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Proportion of subjects that developed depression symptoms during the study compared to the total population of subjects enrolled in the study
Time Frame: Initial visit (Day 0) to 24 months
Initial visit (Day 0) to 24 months

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
August 1, 2008

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
