Biomarkers for Feeding Intolerance in Infants With Complex Congenital Heart Defects Undergoing Single Ventricle Staged Palliation

December 13, 2016 updated by: Supriya Nair, The University of Texas Health Science Center, Houston
The purpose of this study is to investigates serum and stool biomarkers as predictors for post-operative feeding intolerance in infant patients with complex congenital heart defects who undergo single ventricle staged palliation surgery.

Study Overview

Status

Status

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.

Study Type

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

1 day to 3 years (CHILD)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

The study population will be infants with complex congenital cyanotic heart disease requiring single ventricle staged palliation surgery at Children's Memorial Hermann Hospital (CMHH) at the Texas Medical Center. This will include neonates undergoing single ventricle staged palliation in the form of (a) Norwood-type procedure, (b) systemic-to-pulmonary artery shunt procedure, or (c) pulmonary artery banding.

Description

Inclusion Criteria:

  • Full term gestational period (37 weeks gestation or greater)
  • minimum of 2.5kg or greater body weight
  • diagnosis of single ventricle physiology, or complex congenital cyanotic heart disease requiring staged palliation surgery in the form of Norwood-type procedure, systemic-to-pulmonary artery shunt, or pulmonary artery banding.

Exclusion Criteria:

  • Have diseases affecting other organs,
  • have major congenital anomalies such as Hirschsprung disease, imperforate anus, CHARGE syndrome, or VACTERL association.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
Feeding tolerant
Patients that are able to reach 80-100% of full enteral feeds (whether fed by mouth or through a nasogastric tube) 7 days after the initiation of feeds. Patients will be excluded from this group if they are ever diagnosed with NEC at any time during this hospitalization.
Other: Feeding tolerant
Feeding intolerant
Patients with GI symptoms (vomiting, abdominal distention, diarrhea, hematemesis, and/or hematochezia) that persist for 48 hours or longer while needing to be NPO, this patient is retrospectively categorized into the feeding intolerance group. Patients with feeding intolerance may also include infants that are made NPO, placed on bowel rest, and are started on antibiotics to rule out NEC, but are never diagnosed with NEC. Exclusion criteria include patients that are continued on antibiotics for greater than 48 hours due to diagnosed bacterial sepsis or diagnosed NEC, and those that have a positive blood, urine, or sputum culture.
Other: Feeding intolerant
Necrotizing enterocolitis
Any infant that is diagnosed (radiographically, by Bell's criteria) with and treated for NEC.
Other: Necrotizing enterocolitis

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
Level of most abundant serum protein as determined by ELISA
Time Frame: baseline (3-5 days after initial cardiac surgery), within three weeks of the initial cardiac surgery
We will select two proteins with top changes that are involved in the pathways for intestinal inflammation, and levels will be determined with either ELISA or other techniques that are available.
baseline (3-5 days after initial cardiac surgery), within three weeks of the initial cardiac surgery
Level of second most abundant serum protein as determined by ELISA
Time Frame: baseline (3-5 days after initial cardiac surgery), within three weeks of the initial cardiac surgery
baseline (3-5 days after initial cardiac surgery), within three weeks of the initial cardiac surgery
Level of stool biomarker interleukin-8 (IL-8) as determined by ELISA

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

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.
December 1, 2016

Primary Completion (ANTICIPATED)

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.
