Changes in Parenteral Nutrition Requirements and BMI in Patients with Parenteral Nutrition-Dependent Short Bowel Syndrome after Stopping Teduglutide—9 Years of Follow-Up

Teduglutide (TED) is widely used in patients with short-bowel-syndrome-associated intestinal failure (SBS-IF) to enhance intestinal adaptation and reduce the need for parenteral support (PS). There are limited data on the effects of discontinuing TED. In this study, we describe the changes in parenteral nutrition (PN) requirements and body mass index (BMI) in a 9-year follow-up of patients receiving home parenteral nutrition after discontinuation of the TED treatment. We performed a retrospective analysis of changes in weekly PN orders and BMI in all patients with PN-dependent SBS from two Polish home parenteral nutrition (HPN) centers who received teduglutide between 2009 and 2013 and still required HPN 9 years after discontinuation of the TED treatment. Data included in the analysis were collected prospectively at mandatory visits to the HPN centers at 12, 24, 60, 84, and 108 months after drug discontinuation and compared with values before and after TED treatment. Weekly PN volume values varied significantly between all of the above time points from baseline to 9 years after TED discontinuation (χ² = 34.860, p < 0.001). After an initial increase within the first year after treatment discontinuation (not statistically significant), the PN volume requirements remained stable for 4 years and increased 5–9 years after treatment discontinuation. The rate of patients requiring an increase in PN volume was 84.62% at 60 and 84 months and 92.30% at 108 months. At 9 years after cessation of the TED treatment, 53.85% of the study group required a 21.21% increase in PN volume compared with values before treatment. The need for PN volume in patients with PN-dependent SBS who discontinued the TED treatment increased within the first year and 4–5 years after treatment cessation, and in some cases might even exceed pretreatment values after 9 years.
