Effectiveness and Safety of Teduglutide Treatment in Adult Patients with Short Bowel Syndrome: A Case Series and Review of Current Evidence — Journal of clinical medicine 2026

Background: Short bowel syndrome (SBS) is the leading cause of chronic intestinal failure and is frequently associated with long-term dependence on parenteral nutrition (PN) and intravenous fluids. Teduglutide, a glucagon-like peptide-2 (GLP-2) analogue, promotes intestinal adaptation and has been demonstrated to reduce parenteral support requirements. However, real-world data from the Greek population are scarce. Methods: We conducted a non-interventional, multicenter, retrospective cohort study across 5 centers in Greece, including adult patients with SBS receiving teduglutide therapy. Demographic and clinical characteristics, parenteral nutrition and intravenous fluid requirements, body mass index (BMI), laboratory parameters, and adverse events were recorded at baseline and during follow-up at weeks 4, 12, 26, and 52. Results: Eight adult patients with SBS were included (75% female),…

[Use of teduglutide in short bowel syndrome in infants, children and adolescents: Position paper of the working group "Chronic intestinal failure" of the Society for Paediatric Gastroenterology and Nutrition (GPGE)] — Zeitschrift fur Gastroenterologie 2026

AbstractPaediatric short bowel syndrome (SBS) with chronic intestinal failure (IF) is a rare, complex and potentially life-threatening condition. The main causes in children are necrotizing enterocolitis, volvulus, congenital malformations, and other enteropathies. The resulting reduced intestinal absorption capacity often requires parenteral nutrition (PN), which is associated with complications such as catheter infections, liver disease, and thrombosis, as well as significant limitations in quality of life. The goal of multidisciplinary treatment is to achieve enteral autonomy, prevent complications, and improve quality of life. With the introduction of the glucagon-like peptide-2 analogue (GLP-2-analogue) teduglutide, an additional therapeutic option is available that can improve fluid and nutrient absorption and reduce the need for parenteral support, up to partial or complete weanin…

Delayed presentation of a retained colonic segment in a child with intestinal failure on teduglutide — JPGN reports 2025

Teduglutide is a glucagon-like peptide 2 (GLP-2) analogue that was approved by the United States Food and Drug Administration for the treatment of pediatric (>1 year) intestinal failure due to short bowel syndrome in 2019. GLP-2 analogues promote rapid intestinal adaptation, increasing the absorptive capacity of residual intestine after surgical resection to aid the achievement of enteral autonomy or reduce parenteral nutrition requirements. Despite relatively few reported side effects, there is a theoretical risk of proliferative complications. Here we present an intriguing case of a pediatric patient found to have a decade-long retained, discontinuous segment of colon from a surgical procedure performed in infancy, which became clinically significant after a period of treatment with teduglutide.

Efficacy of Teduglutide in Pediatric Short Bowel Syndrome: Association with Citrulline Levels and Anatomical Location of Remnant Small Intestine — Children (Basel, Switzerland) 2025

Background/Objectives: Short bowel syndrome (SBS) is the leading cause of pediatric intestinal failure. Plasma citrulline is considered a marker indicating an enterocyte volume and may help evaluate the response to teduglutide; however, this interpretation may vary depending on the remnant bowel anatomy. Methods: We conducted a retrospective case series of four pediatric patients with SBS (aged Results: This study included two males and two females. All patients showed an increase in plasma citrulline levels and a reduction in the requirement for parenteral nutrition (PN) after 12 months of teduglutide treatment. In SBS type 2 (jejunocolic anastomosis), citrulline levels increased by 114% and 52%, with PN reduction rates of 100% and 30%, respectively. In SBS type 3 (jejunoileal anastomosis), citrulline levels increased by 13.6% and 34%, with PN reductions of 33% and 73%, respectively. Co…
