A Study to Improve the Awareness of Mucopolysaccharidosis Type II in Brazil

May 6, 2022 updated by: Takeda

Mucopolysaccharidosis Type II in Brazil: A Retrospective Secondary Database Study (Informatics Department of Brazilian Health System - DATASUS)

The main aims of the study are to learn about the percentage of mucopolysaccharidosis type II (MPS II) in adults in Brazil as well as about the diagnosis process. No study medicines will be provided to participants in this study. The data available for participants diagnosed with MPS II in DATASUS (a database of the Informatics Department of Brazilian Health System) will be reviewed. No clinic visits will be required as part of participation in this study.

Study Overview

Conditions

Conditions

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.

Intervention / Treatment

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.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

Other: No Intervention
This is a non-interventional study.

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
Number of Participants Diagnosed With MPS II
Time Frame: From January 1, 2008 to September 30, 2020
Number of participants diagnosed with MPS II will be reported based on the retrospective data of participants collected from the database (DATASUS).
From January 1, 2008 to September 30, 2020
Number of Participants with Comorbidities Associated with MPS II
Time Frame: From January 1, 2008 to September 30, 2020
Comorbidities will be like respiratory infections, carpal tunnel syndrome and hernia. Number of participants with comorbidities associated with MPSII will be reported based on the retrospective data of participants collected from the database (DATASUS).

Age of MPS II Diagnosis
Time Frame: From January 1, 2008 to September 30, 2020
Age of MPS II diagnosis will be calculated from the date of birth and date of diagnosis. Retrospective data of participants will be collected from the database (DATASUS).
From January 1, 2008 to September 30, 2020

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
Measure Description
Time Frame
Number of Health Care Professionals Who Diagnosed MPS II
