Urinary PGE-M to help predict acute appendicitis in children

Prostaglandin-E Urinary Metabolite (PGE-M) as a Predictor of Acute Appendicitis in Children

KBC Split · NCT07008092

We will test whether a urine marker called PGE-M can help diagnose acute appendicitis in children ages 5 to 17 who come in with sudden belly pain.

What this trial studies

This is a 12-month observational study enrolling about 100 children aged 5–17 who present with acute abdominal pain and signs suggestive of appendicitis at the University Hospital of Split. Participants will have routine labs and a urine sample collected to measure prostaglandin E urinary metabolite (PGE-M) levels, with clinical course, imaging, surgical findings, and final diagnosis recorded. Investigators will compare PGE-M levels between children with confirmed appendicitis and those with other causes of abdominal pain to see if PGE-M is higher in appendicitis. The study involves minimal additional risk because urine and routine blood samples are collected as part of care.

Who should consider this trial

Good fit: Children aged 5 to 17 who present with acute abdominal pain and clinical signs suggestive of acute appendicitis and who do not have significant comorbidities qualify for this study.

Not a fit: Children outside the 5–17 age range, those with prior abdominal surgery, chronic or malignant disease, pregnancy, or whose pain is clearly due to another diagnosis are unlikely to benefit from this study.

Why it matters

Potential benefit: If successful, using urinary PGE-M could help doctors diagnose appendicitis faster and more accurately, reducing missed cases and unnecessary surgeries.

How similar studies have performed: PGE-M has been reported elevated in other inflammatory conditions, but using urinary PGE-M to diagnose pediatric appendicitis is relatively novel and not yet well established.
