Insights
Octreotide effectively treated pediatric gastrointestinal disorders, reducing bleeding and improving chronic diarrhea. Close monitoring is essential due to potential serious adverse events.
Area of Science:
- Pediatric Gastroenterology
- Clinical Pharmacology
- Medical Therapeutics
Background:
- Octreotide is a synthetic analog of somatostatin.
- Its use in pediatric gastrointestinal disorders is varied.
- This study reviews its application in a pediatric cohort.
Purpose of the Study:
- To evaluate the efficacy and safety of octreotide.
- To assess octreotide's role in treating diverse pediatric GI conditions.
- To report on dosing, effectiveness, and adverse events.
Main Methods:
- Pharmacy database search for pediatric patients receiving octreotide for GI diseases.
- Retrospective chart review.
- Analysis of indications, dosage, treatment outcomes, and adverse events.
Main Results:
- Eleven patients with massive GI bleeding showed reduced transfusion needs (23 ± 9 to 8 ± 15 mL/kg, P<0.01).
- Four patients with pancreatic pseudocyst/ascites experienced resolution.
- Three patients with chylothorax and two with chronic diarrhea showed significant improvement; one with dumping syndrome responded rapidly. Four patients experienced adverse events, including Q-T prolongation and hyperglycemia.
Conclusions:
- Octreotide is a valuable therapeutic option for pediatric gastroenterologists.
- It demonstrates efficacy across a spectrum of gastrointestinal disorders.
- Vigilant patient monitoring is crucial due to potential serious adverse events.
Background/Aim:
We report our experience with the use of octreotide as primary or adjunctive therapy in children with various gastrointestinal disorders.
Patients And Methods:
A pharmacy database identified patients who received octreotide for gastrointestinal diseases. Indications for octreotide use, dosing, effectiveness, and adverse events were evaluated by chart review.
Results:
A total of 21 patients (12 males), aged 1 month to 13 years, were evaluated. Eleven received octreotide for massive gastrointestinal bleeding caused by portal hypertension-induced lesions (n=7), typhlitis (1), Meckel's diverticulum (1), and indefinite source (2). Blood transfusion requirements were reduced from 23 ± 9 mL/kg (mean ± SD) to 8 ± 15 mL/kg (P<0.01). Four patients with pancreatic pseudocyst and/or ascites received octreotide over 14.0 ± 5.7 days in 2 patients. In 3 children, pancreatic pseudocyst resolved in 12 ± 2 days and pancreatic ascites resolved in 7 days in 2. Three patients with chylothorax received octreotide for 14 ± 7 days with complete resolution in each. Two infants with chronic diarrhea received octreotide over 11 ± 4.2 months. Stool output decreased from 85 ± 21 mL/kg/day to 28 ± 18 mL/kg/day, 3 months after initiation of octreotide. The child with dumping syndrome responded to octreotide in a week. Adverse events developed in 4 patients: Q-T interval prolongation and ventricular fibrillation, hyperglycemia, growth hormone deficiency, and hypertension.
Conclusion:
Octreotide provides a valuable addition to the therapeutic armamentum of the pediatric gastroenterologist for a wide variety of disorders. Serious adverse events may occur and patients must be closely monitored.
