Fontan-Sprechstunde

September 28, 2022 updated by: University of Erlangen-Nürnberg Medical School

Prospektive Erfassung Von standardmäßig Erhobenen Daten im Rahmen Der Erlanger Fontan-Sprechstunde Zur Behandlung Und Überwachung Von PatientInnen Mit univentrikulärem Herzfehler im Sinne Einer Fontan-Zirkulation

After successful Fontan surgery, the risk of mortality in childhood is only low. Unfortunately, some of the patients suffer from Fontan-typical long-term complications in the long-term course, whereby protein loss neuropathy must be mentioned in particular, which is described in the literature with an incidence of 3-14% (1, 2) and still has a 5-year risk of death of 6-12% today (2, 3). Protein loss tereopathy leads to loss of protein in the intestine and subsequently to diarrhea and edema. Other problems concern the liver, which can develop cirrhosis due to chronic congestion (4-6). Cardiac can lead to heart failure and arrhythmias.

The registry study described in this protocol is intended to identify factors that influence the treatment outcome of patients in the Fontan circulation in the long term through systematic prospective documentation of the data from our standardized and guideline-oriented treatment.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.
Recruiting

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

In particular, the following points will be scientifically analyzed:

  1. The development of lymphatic drainage disorders (7-9)
  2. The cellular changes of the immunological system and metabolome (10) In addition to the clinical routine, weight-adapted EDTA blood for the isolation of peripheral blood mononuclear cells (PBMCs) for the scientific investigation of immunological changes and serum for the analysis of the metabolome will be examined at three times (Figure 1: Times 2, 4, 7) as part of a routine blood sample (10).
  3. The recording and treatment of psychological, social and developmental abnormalities with the help of standardized questionnaires.
  4. The evaluation of special sonography examinations of the liver and kidney in the long-term course, as well as their treatment.
  5. The assessment of the hemodynamic peculiarities and the classification with regard to Cardiac function in the long-term course of patients with Fontan circulation.
  6. The assessment of various laboratory parameters as risk parameters for the development of complications.
  7. The recording of cardiopulmonary performance in the long-term course and its ability to be influenced by education regarding sporting activity and the handing over of an individualized training plan.
  8. The influence of physical activity on possible complications of Fontan circulation.
  9. The influence of early psychological, nutritional, or social intervention in the event of abnormalities on later complications of Fontan circulation.

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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 60 years (Child, Adult)

Accepts Healthy Volunteers

No

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.
