Chest Wall Deformities in Children - Epidemiological Data

December 6, 2021 updated by: Dr. med. Julian Trah, Universitätsklinikum Hamburg-Eppendorf
Pectus excavatum (PE) or funnel breast is the most common congenital deformity of the chest wall, which occurs in about 1 in 400 births with a boy to girl ratio of 4: 1 to 3: 1. The etiology of PE is largely undefined, but there are numerous indications that genetic factors play a role in the development of PE. Up to 40% of patients report affected family members with similar congenital deformities. In many families, PE follows a pattern that would be compatible with an autosomal dominant or recessive pattern of inheritance. The data on the frequent occurrence of PE in family members fluctuate greatly and only a few genes associated with a PE have been identified so far.

Study Overview

Indicates the current recruitment status or the expanded access status.

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

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. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Previous studies suggest that sulfation of proteoglycans plays a crucial role in the normal development of cartilage and bone and could therefore be crucial in the genesis of the disease. The main catalytic machinery responsible for the biosynthesis and breakage of sulfate esters in the proteoglycans consists of various enzymes and transporters. Mutations in Sphingosine Kinase 1 (SK1) and Sphingosine Kinase 2 (SK2) genes that encode the transmembrane transporters of sulfate or enzymes that are involved in 3'-phosphoadenosine 5'-phosphosulfate (PAPS) synthesis have been identified as the cause of several inherited diseases that all have skeletal system deformities.

Connections between chest wall deformities with syndromes (e.g. Marfan, Noonan), anomalies (e.g. Poland, Moebius) or associations (e.g. Cantrell Pentalogy, PHACE) are well known. In contrast, there have so far been hardly any genetic studies of the isolated congenital chest wall deformities. Epidemiological data are insufficient and only a few groups deal with the inheritance and the incidence of this disease when it occurs in isolation.

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

6 years to 30 years (Child, Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Sampling Method

Non-Probability Sample

Design Details

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
Time Frame
familial accumulation of breast wall deformities Questionnaire
Time Frame: Through study completion, an average of 1 year
Through study completion, an average of 1 year

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
Recording of clinical side effects on the familial accumulation of chest wall deformities
Time Frame: Through study completion, an average of 1 year
Through study completion, an average of 1 year

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

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.
September 1, 2019

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.
