  Purpose

Necrotizing enterocolitis (NEC)is a severe, sometimes life-threatening inflammation of the intestine that occurs most often in premature babies. If it progresses, the wall of the intestine may break open, spilling bacteria and stool into the abdomen. Parts or all of the intestine may die. Despite 30 years of clinical studies, the cause of NEC remains unknown.

In this study, in addition to clinical data collection, blood and urine samples from infants with NEC will be examined for patterns of proteins and/or genetic characteristics. It is hoped that it will be possible to diagnose and treat infants earlier in the disease process as well as to know which infants will progress to the severest form of NEC. Earlier treatment could lead to a better outcome for these babies.

Further study details as provided by Yale University:

Primary Outcome Measures:
  • Proteomic and genomic profiles will be matched to NEC clinical endpoints [ Time Frame: April 2007 to December, 2008 ] [ Designated as safety issue: No ]

Biospecimen Retention:   Samples With DNA

Biospecimen Description:

Blood Urine


Estimated Enrollment: 88
Study Start Date: April 2007
Estimated Study Completion Date: December 2008
Groups/Cohorts
Cases
Infants who meet the entry criteria
Controls
Banked blood samples held at Stanford University Core Laboratory will constitute controls. Proteomic and genomic profiles in blood samples of cases will be compared with blood samples of controls.

Detailed Description:

Inclusion Criteria:

Patients must meet at least one criterion from each of the following three categories to be enrolled into the study.

Historical Factors

  • Feeding intolerance defined as vomiting of two or more feedings within 24 hours or any vomitus containing bile, the presence of gastric residuals of volume greater than 6cc/kg or any aspirate containing bile
  • Apneic/bradycardic episodes(cessation of breathing or slowing of heart rate)
  • Oxygen desaturation episode not otherwise explained (dangerously low concentration of oxygen in the blood)
  • Occult or gross blood in stools

Physical Examination Findings

  • Abdominal distention recorded by practitioner
  • Capillary refill time greater than 2 seconds
  • Abdominal wall discoloration
  • Abdominal tenderness

Radiologic Findings

  • Pneumatosis intestinalis
  • Portal venous gas
  • Ileus
  • Dilated bowel
  • Pneumoperitoneum
  • Air/fluid levels
  • Thickened bowel walls
  • Ascites or peritoneal fluid
  • Free intraperitoneal air
  • Abnormal bowel gas

Exclusion Criteria:

  • Major gastrointestinal anomaly
  • Prior abdominal surgery

Clinical Outcome Measures:

  • Surgery
  • Reaching full feedings

Final Outcome Measures:

Genomic and proteomic profiles will be matched to clinical outcomes
