Evaluation of the Effectiveness of Teduglutide Treatment in Patients with Short Bowel Syndrome in Slovakia-Multicenter Real-World Study.

(1) Background: We present the first real-world-data study on teduglutide-treated SBS patients in the Slovak Republic and the first study to enable the comparison of the effects of teduglutide treatment between the adult and pediatric populations. (2) Methods: This was a non-interventional retrospective cohort study of adult and pediatric SBS patients treated with teduglutide. Primary and secondary endpoints were the results of teduglutide use at 12 weeks and 6 months after the initiation of treatment, compared to baseline. (3) Results: Teduglutide treatment led to a statistically significant reduction in the volume of intravenous hydration, HPN caloric intake, HPN and intravenous hydration applications per week and to increased urine output in adult patients. The results in the pediatric population were similar, but not statistically significant. A complete weaning off HPN was achieved in 57.14% of all patients (50.00% of children; 62.50% of adults) after a median of 0.99 years of teduglutide treatment (1.07 and 0.98 years for children and adults, respectively). (4) Conclusions: Teduglutide treatment in SBS patients leads to considerable reduction in or even weaning off PN in both pediatric and adult patients.

Cost-effectiveness of teduglutide in adult patients with short bowel syndrome - a European socioeconomic perspective.

BACKGROUND: Short bowel syndrome with intestinal failure (SBS-IF) is a rare but devastating medical condition. An absolute loss of bowel length forces the patients into parenteral support dependency and a variety of medical sequelae, resulting in increased morbidity and mortality. Interdisciplinary treatment may include therapy with the effective but expensive intestinotrophic peptide teduglutide. OBJECTIVES: A time-discrete Markov model was developed to simulate the treatment effect [lifetime costs, quality-adjusted life years (QALYs), and life years (LYs)] of teduglutide plus best supportive care compared with best supportive care alone in patients with SBS-IF. METHODS: The health status of the model was structured around the number of days on PS. Clinical data from 3 data sets were used: 1) an Austrian observational study (base case), 2) pooled observational cohort studies, and 3) a prospective study of teduglutide effectiveness in parenteral nutrition-dependent short bowel syndrome subjects. Direct and indirect costs were derived from published sources. QALYs, LYs, and costs were discounted (3% per annum). RESULTS: Under the base case assumption, teduglutide is associated with costs of 2,296,311 € per patient and 10.78 QALYs (13.74 LYs) over a lifetime horizon. No teduglutide is associated with 1,236,816 € and 2.24 QALYs (8.57 LYs). The incremental cost-utility ratio (ICUR) amounts to 123,945 €. In case of the pooled clinical data set, the ICUR increases to 184,961 €. If clinical data based on the study of teduglutide effectiveness in parenteral nutrition-dependent short bowel syndrome subjects were used, the ICUR increased to 235,612 €. CONCLUSIONS: Teduglutide in treating patients with SBS-IF meets the traditional cost-effectiveness criteria from a European societal perspective. Nevertheless, the varying concentrations of teduglutide efficacy leave a degree of uncertainty in the calculations.

Teduglutide-induced acute gastric mucosal necrosis in short bowel syndrome with hepatorenal failure: Case report.

INTRODUCTION: Short bowel syndrome (SBS) resulting from acute aortic dissection (AAD)-induced visceral malperfusions leads to chronic intestinal failure (CIF), necessitating patients to adopt home parenteral nutrition to prevent malabsorption. Teduglutide (TED), a glucagon-like peptide-2 analog, is a promising pharmacotherapy for intestinal rehabilitation that reduces parenteral support and improves the quality of life. Gastric mucosal necrosis, a rare gastrointestinal disorder, had never been observed as an adverse event relevant to this drug. We report a case of mucosal necrosis in the stomach after TED treatment for SBS-CIF with hepatorenal failure. PRESENTATION OF CASE: A 68-year-old Japanese man who underwent massive intestinal resection for AAD experienced malnutrition and diarrhea caused by SBS-CIF. The patient received TED to improve intestinal absorption and entero-hepatic circulation besides controlling infectious diseases. Endoscopy showed mucosal hyperplasia in the stomach and duodenum 1.5 months after TED administration. The patient consented to enteral nutrition via a nasogastric tube because of anorexia. The nutritional status gradually improved after initiating enteral feeding. However, the patient experienced hematemesis 13 days after enteral feeding, and endoscopy revealed acute gastric mucosal necrosis, followed by fatal septic shock. DISCUSSION: For patients with SBS, TED is expected to increase intestinal absorption through epithelial proliferation. When SBS is accompanied by multiple ischemic organ failure, TED therapeutic effects remain unclear as malnutrition-associated infectious diseases are refractory, and many underlying mechanisms can be involved. CONCLUSION: TED administration should be deliberately considered for patients with SBS-CIF and multiple organ failure experiencing uncontrolled systemic infection.

Use of Teduglutide in the Management of Gastrointestinal Graft-versus-Host Disease in Children and Young Adults.

Loss of intestinal L cells and reduced levels of glucagon-like peptide-2 (GLP-2) have been implicated in acute graft-versus-host disease (GVHD) in murine models. Teduglutide, a human recombinant GLP-2 analog, may be beneficial in acute gastrointestinal (GI) GVHD owing to its known tissue protective and regenerative functions. We retrospectively reviewed patients who received teduglutide for treatment of GI GVHD. Endoscopy was performed at diagnosis and at completion of the teduglutide course. GLP-1 immunohistochemistry (IHC) was performed at diagnosis and the end of teduglutide therapy in 2 patients to evaluate L cells. We initiated daily teduglutide 0.05 mg/kg subcutaneously as adjunctive therapy in 3 pediatric patients with refractory GI GVHD. All 3 patients had resolution of GI GVHD following completion of the teduglutide course, as evidenced by reduced apoptosis and regenerative changes on post-treatment endoscopy. Reportable GLP-1 IHC in 2 patients demonstrated increased L cells at the end of teduglutide treatment compared to at diagnosis. No adverse effects to teduglutide were observed. Teduglutide is a promising adjunctive and non-immune suppressive agent for managing acute GI GVHD.

Improved Outcomes Associated With Teduglutide Use in Patients With Both Short Bowel Syndrome and Crohn's Disease.

Introduction: Crohn's disease (CD) with short bowel syndrome (SBS) can present as chronic intestinal failure (CIF) often requiring nutritional support. Teduglutide is a treatment option for these patients. We investigated clinical outcomes of CD-CIF patients with SBS treated with teduglutide. Methods: Adults with CD-CIF and SBS who received teduglutide were identified at a tertiary care academic center between 2012 and 2023. Data was collected retrospectively. Primary outcome measured was reduction in parenteral support (PS) by ≥20% volume, with PS defined as utilization of parenteral nutrition (PN) or intravenous fluids (IVF). Several secondary outcomes included immunosuppressive medication changes, subjective symptom improvement, and stool output. Results: We identified 32 patients with CD-CIF and SBS receiving teduglutide. Comparing clinical outcomes before and after teduglutide, 26 of 32 patients achieved the primary outcome of ≥20% PS reduction. A decrease was seen in patients requiring PN + IVF, with corresponding increases in patients requiring PN only and IVF only. Among all 3 groups, a total of 23 patients received PN prior to teduglutide, which decreased to 14 following teduglutide. Weekly PN volume reduced from 7.00 to 3.55 L and weekly frequency decreased from 7.00 to 3.00 instances (P < .01). Reductions in weekly volume and frequency were observed among all patients receiving IVF support (25 vs 15). Secondary outcomes showed improvement in patient reported subjective symptoms (84.4%), stool output (90.6%), patients meeting criteria for diarrhea/high ostomy output (27 vs 14), and use of unique antidiarrheal medications (3.0 vs 2.0). Conclusions: This retrospective case series demonstrated improved clinical outcomes in patients with CD-CIF and SBS treated with teduglutide resulting in decreased PS requirements, antidiarrheal medications requirement, and stool output without significant effects on immunosuppressive therapy.

Long-term outcomes and adverse effects of teduglutide in patients with short bowel syndrome: Highlighting hyperamylasemia and hyperlipasemia.

PURPOSE: Short bowel syndrome is a malabsorptive condition that occurs due to surgical removal or a congenital absence of a significant portion of the small intestine. Patients with short bowel syndrome often rely on parenteral support for extended periods or even their entire lives. Teduglutide, a glucagon-like peptide-2 analog, has shown promising results in reducing dependency on parenteral support in these patients by promoting intestinal adaptation and enhancing nutrient absorption. However, the long-term safety of teduglutide remains a concern, particularly with respect to its potential for the development of hyperamylasemia and hyperlipasemia. METHODS: This study involved patients who received teduglutide from December 2012 to December 2022 at Boston Medical Center. We evaluated outcomes and adverse events, focusing on hyperamylasemia and hyperlipasemia, through chart review. RESULTS: Thirteen eligible patients were identified who had used teduglutide. Of these, the majority (84.6%) experienced a reduction in parenteral support. A high incidence (72.7%) of nonpathological pancreatic enzyme elevation was observed in patients treated with teduglutide. These elevations were often dose dependent and were not associated with any clinical signs of acute pancreatitis or abnormal imaging findings. CONCLUSION: This study highlights the need for further investigations into the long-term safety of teduglutide and the importance of closely monitoring amylase and lipase levels in patients undergoing treatment with teduglutide.

Use of teduglutide in adults with short bowel syndrome-associated intestinal failure.

Short bowel syndrome (SBS) is a rare gastrointestinal disorder associated with intestinal failure (SBS-IF) and poor health-related outcomes. Patients with SBS-IF are unable to absorb sufficient nutrients or fluids to maintain significantly metabolic homeostasis via oral or enteral intake alone and require long-term intravenous supplementation (IVS), consisting of partial or total parenteral nutrition, fluids, electrolytes, or a combination of these. The goal of medical and surgical treatment for patients with SBS-IF is to maximize intestinal remnant absorptive capacity so that the need for IVS support may eventually be reduced or eliminated. Daily subcutaneous administration of the glucagon-like peptide 2 analog, teduglutide, has been shown to be clinically effective in reducing IVS dependence and potentially improving the health-related quality of life of patients with SBS-IF. The management of patients with SBS-IF is complex and requires close monitoring. This narrative review discusses the use of teduglutide for patients with SBS-IF in clinical practice. The screening of patient eligibility for teduglutide treatment, initiation, monitoring of efficacy and safety of treatment, adapting or weaning off IVS, and the healthcare setting needed for SBS-IF management are described, taking into consideration data from clinical trials, observational studies, and clinical experience.

The Impact of Teduglutide on Real-Life Health Care Costs in Children with Short Bowel Syndrome.

OBJECTIVES: To analyze the real-life health care costs of home parenteral nutrition (HPN) in children with short bowel syndrome with intestinal failure (SBS-IF) before and after treatment with teduglutide, and to compare those with costs of children with SBS-IF not treated with teduglutide. STUDY DESIGN: All consecutive children with SBS-IF on HPN treated with subcutaneous teduglutide starting from 2018 through 2020 in a tertiary French referral center were retrospectively included. These patients were matched to children with SBS-IF on HPN followed during the same 3-year period who were eligible for the teduglutide but were not treated. HPN direct medical costs included: home-care visits, HPN bags, hospital admissions, and teduglutide. A comparison of costs before/after treatment, and between patients treated/not treated was performed. RESULTS: Sixty children were included: 30 (50%) treated with teduglutide and 30 (50%) untreated. In the treated group, the median total costs of HPN significantly decreased after 1 (p<0.001) and 2 years of treatment (p<0.001) from 59.454 euros/year/patient to 43.885 euros/year/patient and 34.973 euros/year/patient, respectively. Comparing patients treated and not treated, the total HPN costs/year/patient were similar at baseline (p=0.6) but were significantly lower in the teduglutide-treated group after 1 (p=0.006) and 2 years of treatment (p<0.001). When adding the cost of teduglutide into the analysis, the total cost increased significantly in the treated group, and remained much higher even after modeling a reduction in the cost of the drug to 1/3 the present cost and PN weaning (p<0.001). CONCLUSIONS: Treatment with teduglutide is associated with a significant reduction in the annual costs of HPN but still remains expensive because of the drug itself. Finding cost saving strategies is essential.

Gastric Foveolar Hyperplastic Polyps in 2 Children With Short Bowel Syndrome on Long-Term Teduglutide.

The natural history of short bowel syndrome involves intestinal adaptation wherein the remnant small intestine undergoes histologic and anatomic changes aimed at increasing absorption. Teduglutide-a glucagon-like peptide 2 analog approved for pediatric use in 2019-stimulates this process by causing proliferation of intestinal epithelial cells resulting in increased villous height and crypt depth. Food and Drug Administration approval for pediatric patients followed safety and efficacy studies in children that were limited to 24-week duration. Pediatric-specific postmarketing studies evaluating long-term safety and efficacy are underway. Formation of colorectal polyps has been repeatedly observed in studies of adult patients on long-term teduglutide, including in individuals without endoscopic evidence of polyps before treatment initiation. Recent studies, however, suggest increased risk of small bowel hyperplastic and dysplastic polyp formation with long-term glucagon-like peptide 2 analog use. We report 2 cases of small bowel foveolar hyperplastic polyps found during surveillance endoscopies after 1 year of treatment with teduglutide.

Cost-utility analysis of teduglutide compared to standard care in weaning parenteral nutrition support in children with short bowel syndrome.

BACKGROUND & AIMS: A growing proportion of children with short bowel syndrome (SBS) remain dependent on long-term parenteral nutrition (PN). Teduglutide offers the potential for more children to decrease PN support and achieve enteral autonomy (EA), but at a significant expense. This study aims to assess the incremental costs of teduglutide plus standard of care compared to standard of care alone in weaning PN support per quality-adjusted life year (QALY) gained in children with SBS. METHODS: This is a cost-utility analysis comparing teduglutide with standard of care alone in children with SBS. A microsimulation model of children with SBS on PN aged 1-17 years was constructed over a time horizon of six years, with a cycle length of one month. The study adopted the healthcare system and societal payer perspectives in Ontario, Canada. The health outcome measure was QALYs, with results expressed in terms of incremental costs and QALYs. Scenario analyses were performed to examine the effects of different time horizons, timing of teduglutide initiation, and modeling cost of teduglutide based on pediatric weight-dosing. RESULTS: Incremental healthcare system costs for teduglutide compared to standard of care were CAD$441,314 (95% CI, 414,006 to 441,314) and incremental QALYs were 1.80 (95% CI, 1.70 to 1.89) resulting in an incremental cost-effectiveness ratio (ICER) of CAD$285,334 (95% CI, 178,209 to 392,459) per QALY gained. Incremental societal costs were CAD$418,504 (95% CI, 409,487 to 427,522) and incremental societal QALYs were 1.91 (95% CI, 1.85 to 1.98) resulting in an ICER of CAD$261,880 (95% CI, 136,887 to 386,874) per QALY gained. Scenario analysis showed that teduglutide was cost-effective when it was started two years after intestinal resection (ICER CAD$48,741, 95% CI, 17,317 to 80,165) and when its monthly cost was adjusted using weight-based dosing, avoiding wastage of the remaining 5 mg dose vial (Teduglutide dominated over SOC as the less costly and most effective strategy). CONCLUSIONS: Although teduglutide was not cost-effective in weaning PN support in children with SBS, starting teduglutide once natural intestinal adaptation is reduced and adjusting its monthly cost to reflect cost by volume as dictated by weight-based dosing rendered the intervention cost-effective relative to standard of care. These results indicate the potential for clinicians to re-assess optimal time for initiation of teduglutide after intestinal resection, drug manufacturers to consider the use of multi-dose or paediatric-dose vials, and the opportunity for decision-makers to re-evaluate teduglutide funding.

Predictive Potential of Biomarkers of Intestinal Barrier Function for Therapeutic Management with Teduglutide in Patients with Short Bowel Syndrome.

INTRODUCTION: The human intestinal tract reacts to extensive resection with spontaneous intestinal adaptation. We analyzed whether gene expression analyses or intestinal permeability (IP) testing could provide biomarkers to describe regulation mechanisms in the intestinal barrier in short bowel syndrome (SBS) patients during adaptive response or treatment with the glucagon-like peptide-2 analog teduglutide. METHODS: Relevant regions of the GLP-2 receptor gene were sequenced. Gene expression analyses and immunohistochemistry were performed from mucosal biopsies. IP was assessed using a carbohydrate oral ingestion test. RESULTS: The study includes 59 SBS patients and 19 controls. Increases in gene expression with teduglutide were received for sucrase-isomaltase, sodium/glucose cotransporter 1, and calcium/calmodulin serine protein kinase. Mannitol recovery was decreased in SBS but elevated with teduglutide (Δ 40%), showed a positive correlation with remnant small bowel and an inverse correlation with parenteral support. CONCLUSIONS: Biomarkers predicting clinical and functional features in human SBS are very limited. Altered specific gene expression was shown for genes involved in nutrient transport but not for genes controlling tight junctions. However, mannitol recovery proved useful in describing the absorptive capacity of the gut during adaptation and treatment with teduglutide.

Teduglutide in amyloidosis-associated intestinal failure.

Amyloidosis is a heterogeneous disease characterized by tissue deposition of abnormally folded fibrillary proteins that can manifest itself by a wide variety of symptoms depending on the affected organs. GI involvement among amyloidosis patients is common. Its clinical manifestation often presents with nonspecific symptoms such as weight loss, diarrhea, and malabsorption. With no specific treatment existing for GI amyloidosis, therapy focuses on impeding amyloid deposition and managing the patients' symptoms with supportive measures. Here, we present an AL-amyloidosis patient with GI involvement and intestinal failure (IF) who was successfully treated with the glucagon-like peptide-2 (GLP-2) analogue teduglutide. Over the course of treatment with teduglutide, the patient was able to achieve independence from parenteral nutrition and experienced a significant improvement in quality of life (QoL) as stool frequency and consistency improved, urinary output was stabilized and body weight as well as body composition improved over the course of teduglutide therapy. With no longer being exposed to the burden and associated risks of parenteral nutrition, we were able to reduce the potential morbidity and mortality rate as well as to improve the patient's overall QoL. Intestinal tissue biopsy workup revealed a histopathological correlate for the clinical response; Congo-Red-positive intestinal depositions almost completely disappeared within 6 months of teduglutide therapy. Implementing intestinotrophic GLP-2 analogue teduglutide may enrich the spectrum of treatment options for amyloidosis patients with IF who are dependent on parenteral support.

Expression, Purification and Characterization of Functional Teduglutide Using GST Fusion System in Prokaryotic Cells.

Purpose: Teduglutide is the first and only FDA-approved drug for long-term treatment of short bowel syndrome (SBS). The current study aimed to present an approach for production of teduglutide using recombinant DNA technology. Methods: The coding gene for teduglutide was cloned into pGEX-2T vector, where coding sequence for factor Xa cleavage site was added between GST and teduglutide coding genes. The GST-teduglutide protein was overexpressed in E. coli BL21 (DE3) strain and affinity purified using glutathione sepharose affinity column. Results: On-column proteolytic activity of factor Xa followed by size exclusion chromatography resulted in the pure teduglutide. Circular dichroism (CD) spectropolarimetry showed that the produced teduglutide folds into mainly α-helical structure (>50%), as expected. In mass spectroscopy analysis, the fragments of teduglutide resulted by cyanogen bromide cleavage as well as those expected theoretically due to mass fragmentation were identified. The functionality of the produced peptide was evaluated by measuring its proliferative effect on Caco2 intestinal epithelial cells, and the results indicated that produced teduglutide induces cell proliferation by 19±0.30 and 33±7.82 % at 1.21 and 3.64 µM concentrations, respectively, compared to untreated cells. Conclusion: Teduglutide was successfully expressed and purified and its functionality and structural integrity were confirmed by in vitro experiments. We believe that the experimental-scale method presented in the current study can be useful for pilot-scale and also industrial-scale production of teduglutide.

Case report: Exploring teduglutide as a therapeutic option for refractory microscopic colitis: insights and implications.

Microscopic colitis is a chronic inflammatory condition of the colon characterized by chronic watery diarrhea, generally with endoscopically normal or nonspecific findings, and can be diagnosed by histopathological examination of colon mucosal biopsies. Some patients experience severe symptoms that do not respond to conventional medical treatment. A glucagon-like peptide-2 (GLP-2) analog, teduglutide, is used in patients with short bowel syndrome (SBS) dependent on parenteral support. In this case report, we describe a patient with microscopic colitis who demonstrated significant symptom improvement following teduglutide treatment.

Revisión sobre la experiencia en vida real de teduglutida / Review of real-life teduglutide experience

Introducción: la teduglutida es un agonista del péptido relacionado con glucagón (aGLP2) eficaz como tratamiento de pacientes con síndrome de intestino corto (SIC) una entidad que afecta a la calidad de vida, suele precisar de nutrición parenteral domiciliaria (NPD) y genera importantes costes sanitarios. El objetivo de la presente revisión narrativa fue evaluar la experiencia en vida real reportada con teduglutida. Métodos y resultados: en vida real un metaanálisis y estudios publicados con 440 pacientes, indican que teduglutida es efectivo pasado el periodo de adaptación intestinal posterior a la cirugía, reduciendo las necesidades de NPD y en algunos casos permite incluso suspenderla. La respuesta es heterogénea, aumenta progresivamente hasta 2 años después del inicio del tratamiento y alcanza el 82 % en algunas series. La presencia de colon en continuidad es factor predictivo negativo de respuesta precoz, pero un factor predictivo positivo para la retirada de NPD. Los efectos adversos más frecuentes son de origen gastrointestinal en las primeras etapas del tratamiento. Hay complicaciones tardías relacionadas con el estoma o con la aparición de pólipos de colon, aunque la frecuencia de estas últimas es muy baja. En adultos son escasos los datos en mejoría de calidad de vida y en coste eficacia. Conclusiones: teduglutida es efectivo y seguro confirmándose en vida real los datos de los ensayos pivotales para tratamiento de pacientes con SIC y permite reducir o incluso suspender en algunos casos la NPD. Aunque parece coste efectivo son necesarios más estudios para identificar aquellos pacientes con mayor beneficio.(AU)

Background: teduglutide is an agonist of glucagon-related peptide (aGLP2) effective as a treatment for patients with short bowel syndrome (SBS), an entity that affects quality of life, usually requires home parenteral nutrition (HPN) and generates significant health costs. The objective of the present narrative review was to assess the real-life experience reported with teduglutide.Methods and results: in real life, one meta-analysis and studies published with 440 patients indicate that Teduglutide is effective after the period of intestinal adaptation after surgery, reducing the need for HPN and in some cases even allowing it to be suspended. The response is heterogeneous, increasing progressively up to 2 years after the start of treatment and reaching 82 % in some series. The presence of colon in continuity is a negative predictor of early response, but a positive predictive factor for the withdrawal of HPN. The most common side effects are gastrointestinal in the early stages of treatment. There are late complications related to the stoma or the occurrence of colon polyps, although the frequency of the latter is very low. In adults, data on improved quality of life and cost-effectiveness are scarce. Conclusions: teduglutide is effective and safe and data from pivotal trials for the treatment of patients with SBS are confirmed in real life and can reduce or even stop HPN in some cases. Although it seems cost-effective, more studies are needed to identify those patients with the greatest benefit.(AU)

Nutritional management of a patient with chronic intestinal failure and hemodialysis receiving teduglutide: A case report.

We present the case of a 35-y-old woman with short bowel syndrome secondary to extensive intestinal resection with associated chronic kidney disease who was undergoing hemodialysis. This patient required permanent supplementation with intradialytic parenteral nutrition because of a high-output end-jejunostomy. The patient was a candidate for treatment with teduglutide, a glucagon-like peptide 2 analog, intending to increase intestinal absorption. A complete nutritional assessment was performed using bioelectrical impedance vector analysis. Teduglutide treatment was successful, and after a 1-y follow-up, the patient had considerably reduced end-jejunostomy output (reduction of 6 L/d) and an improved nutritional status (9.1 kg weight gain, 1.4 kg fat-free mass gain, and a 2.2-degree increase in bioimpedance phase angle). However, we have been unable to reduce intradialytic parenteral nutrition, which the patient requires thrice weekly. No significant secondary effects have occurred because of teduglutide administration. This may be the first reported use of teduglutide in a patient with short bowel syndrome undergoing hemodialysis who was monitored using bioelectrical impedance data during follow-up.

Post-Marketing Use of Teduglutide in a Large Cohort of Adults with Short Bowel Syndrome-Associated Chronic Intestinal Failure: Evolution and Outcomes.

Teduglutide, a GLP-2 analogue, has been available in France since 2015 to treat short-bowel-syndrome (SBS)-associated chronic intestinal failure (CIF) but it remains very expensive. No real-life data on the number of potential candidates are available. The aim of this real-life study was to assess teduglutide initiation and outcomes in SBS-CIF patients. All SBS-CIF patients cared for in an expert home parenteral support (PS) center between 2015 and 2020 were retrospectively included. Patients were divided into two subpopulations: prevalent patients, already cared for in the center before 2015, and incident patients, whose follow-up started between 2015 and 2020. A total of 331 SBS-CIF patients were included in the study (156 prevalent and 175 incident patients). Teduglutide was initiated in 56 patients (16.9% of the cohort); in 27.9% of prevalent patients and in 8.0% of incident patients, with a mean annual rate of 4.3% and 2.5%, respectively. Teduglutide allowed a reduction in the PS volume by 60% (IQR: 40-100), with a significantly higher reduction in incident versus prevalent patients (p = 0.02). The two- and five-year treatment retention rates were 82% and 64%. Among untreated patients, 50 (18.2%) were considered ineligible for teduglutide for non-medical reasons. More than 25% of prevalent SBS patients were treated with teduglutide compared to 8% of incident patients. The treatment retention rate was >80% at 2 years, which could be explained by a careful selection of patients. Furthermore, this real-life study confirmed the long-term efficacy of teduglutide and showed a better response to teduglutide in incident patients, suggesting a benefit in early treatment.

Long-term treatment with teduglutide: a 48-week open-label single-center clinical trial in children with short bowel syndrome.

BACKGROUND: Short bowel syndrome (SBS) is the main cause of intestinal failure in children. OBJECTIVES: This single-center study evaluated the safety and efficacy of teduglutide in pediatric patients with SBS-associated intestinal failure (SBS-IF). METHODS: Children with SBS followed at our center with ≥2 y on parenteral nutrition (PN) and with small bowel length <80 cm who had reached a plateau were consecutively included in the study. At baseline, participants underwent a clinical assessment including a 3-d stool balance analysis, which was repeated at the end of the study. Teduglutide was administered subcutaneously 0.05 mg/kg/d for 48 wk. PN dependence was expressed as the PN dependency index (PNDI), which is the ratio PN non-protein energy intake/REE. Safety endpoints included treatment-emergent adverse events and growth parameters. RESULTS: Median age at inclusion was 9.4 y (range: 5-16). The median residual SB length was 26 cm (IQR: 12-40). At baseline, the median PNDI was 94% (IQR: 74-119), (median PN intake: 38.9 calories/kg/d, IQR: 26.1-48.6). At week 24, 24 (96%) children experienced a reduction of >20% of PN requirements with a median PNDI = 50% (IQR: 38-81), (PN intake: 23.5 calories/kg/d IQR: 14.6-26.2), P < 0.01. At week 48, 8 children (32%) were weaned completely off PN. Plasma citrulline increased from 14 µmol/L (IQR: 8-21) at baseline to 29 µmol/L (IQR: 17-54) at week 48 (P < 0.001). Weight, height, and BMI z-scores remained stable. The median total energy absorption rate increased from 59% (IQR: 46-76) at baseline to 73% (IQR: 58-81) at week 48 (P = 0.0222). Fasting and postprandial endogenous GLP-2 concentrations increased at weeks 24 and 48 compared with baseline. Mild abdominal pain at the early phase of treatment, stoma changes, and redness at the injection site were commonly reported. CONCLUSIONS: Increased intestinal absorption and PN dependency reduction were observed with teduglutide treatment in children with SBS-IF.

Current management of bowel failure due to Crohn's disease in Spain: Results of a GETECCU survey. / Manejo actual del fracaso intestinal por enfermedad de Crohn en nuestro medio: resultados de una encuesta GETECCU.

INTRODUCTION: Intestinal failure is a rare pathology which requires knowledge and highly specialized multidisciplinary management. Crohn's disease (CD) being one of the most frequent causes in adults. MATERIAL AND METHODS: Survey format study carried out within the GETECCU group, included closed format questions about the diagnosis, management and current knowledge of intestinal failure in CD. RESULTS: Forty-nine doctors participated, belonging to different Spanish centers (19 cities). It was considered that a patient suffered from intestinal failure, in 67.3% (33/49 surveyed) when there was a disorder malabsorptive associated regardless of the intestinal length resected, with surgeries resective ileal repeated (40.8%, 20/49), the most frequent cause. It highlights frequent ignorance about the pathology (24.5%) did not know if there were patients in their center and also 40% did not know the pharmacological treatment. A total of 228 patients were registered for follow-up due to intestinal failure of any aetiology, 89 patients (39.5%) were identified with CD. Regarding the therapeutic management of patients with CD and intestinal failure (72.5%) were receiving total parenteral nutrition (NTP) and 24 patients (27%) with teduglutide. Regarding the response to the drug: 37.5% had no response to teduglutide, 37.5% partial response (reduce NTP) and 25% good response (withdrawal of home NTP). In questions related to knowledge about intestinal failure, it was considered limited (53.1%) or very limited (12.2%) by the surveyed. CONCLUSION: It is necessary to carry out a combined management of intestinal failure and CD in the context of a multidisciplinary approach.

A Case Report of Cardiac Failure in a Patient on Teduglutide for High-Output Ileostomy Stoma.

A high volume of ileostomy output in patients with extensive bowel resection can be hard to manage. This leads to extensive loss of fluids and electrolytes along with malabsorption. Medications have traditionally controlled it by delaying intestinal transit and decreasing intestinal and gastric secretion using opiates, loperamide, diphenoxylate, omeprazole, somatostatin, and octreotide. However, many patients depend on parenteral nutrition and fluid and electrolyte infusions, even with optimal drug therapy. Despite the best possible care, they may develop renal failure. Teduglutide is a glucagon-like peptide-2 (GLP-2) analog given as a daily subcutaneous injection, and it has been promising in managing short bowel syndrome. It has been effective in decreasing the dependence on parenteral nutrition. However, improving fluid and electrolyte balance can precipitate cardiac failure in some patients, especially those with borderline cardiac functions, hypertension, and thyroid disorders. This usually presents in the first few months of the initiation of teduglutide therapy and may require stopping the medication. We present the case report of an elderly female with a high-output stoma on parenteral nutrition on teduglutide. There was a significant decrease in stoma output, and parenteral nutritional support could be stopped. However, she presented with worsening dyspnea and was diagnosed with cardiac failure with an ejection fraction of 16%-20%. The baseline ejection fraction was 45%, done six months before this. Coronary angiography showed no stenosis in any vessels, and the decline in left ventricular ejection fraction and fluid overload was attributed to teduglutide therapy.
