Teduglutide improves liver chemistries in short bowel syndrome-associated intestinal failure: Post hoc analysis. Nutr Clin Pract 2024; 39:634-640. [PMID: 38491966 DOI: 10.1002/ncp.11139] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Revised: 02/01/2024] [Accepted: 02/02/2024] [Indexed: 03/18/2024] Open
Abstract
BACKGROUND Chronic hepatic complications are common in patients with short bowel syndrome-associated intestinal failure (SBS-IF). Teduglutide, a glucagon-like peptide-2 analogue, demonstrated efficacy in reducing parenteral nutrition and/or intravenous fluid dependence among patients with SBS-IF in phase 3 clinical studies. METHODS This was a post hoc analysis of pooled data from two separate randomized, double-blind, placebo-controlled, multinational phase 3 clinical studies. Adult patients with SBS-IF with parenteral nutrition and/or intravenous fluid dependence without liver disease at baseline were randomized to treatment with the glucagon-like peptide-2 analogue teduglutide (0.05 or 0.10 mg/kg/day) or placebo subcutaneously once daily for 24 weeks. Mixed-effects models assessed the baseline predictors of change in liver chemistries. RESULTS Between baseline and week 24, teduglutide treatment (n = 109) was associated with least squares mean reductions in aspartate aminotransferase (-7.51 IU/L; P = 0.014), alanine aminotransferase (-12.15 IU/L; P = 0.002), and bilirubin (-5.03 µmol/L [-0.057 mg/dl]; P < 0.001) compared with that of the placebo (n = 59). These values were independent of reductions in parenteral nutrition and/or intravenous fluid dependence. CONCLUSION Teduglutide treatment was associated with reductions in liver chemistries by week 24, which is beneficial for patients with SBS-IF beyond improvements in parenteral nutrition and/or intravenous fluid dependence. Future studies should examine how long-term teduglutide might mitigate the risk of liver disease in patients with SBS-IF.

Obeticholic acid attenuates the intestinal barrier disruption in a rat model of short bowel syndrome. Biochim Biophys Acta Mol Basis Dis 2024; 1870:167221. [PMID: 38718845 DOI: 10.1016/j.bbadis.2024.167221] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Revised: 05/02/2024] [Accepted: 05/03/2024] [Indexed: 05/12/2024]
Abstract
BACKGROUND Short bowel syndrome (SBS) features nutrients malabsorption and impaired intestinal barrier. Patients with SBS are prone to sepsis, intestinal flora dysbiosis and intestinal failure associated liver disease. Protecting intestinal barrier and preventing complications are potential strategies for SBS treatment. This study aims to investigate the effects of farnesoid X receptor (FXR) agonist, obeticholic acid (OCA), have on intestinal barrier and ecological environment in SBS. METHODS AND RESULTS Through testing the small intestine and serum samples of patients with SBS, impaired intestinal barrier was verified, as evidenced by reduced expressions of intestinal tight junction proteins (TJPs), increased levels of apoptosis and epithelial cell damage. The intestinal expressions of FXR and related downstream molecules were decreased in SBS patients. Then, global FXR activator OCA was used to further dissect the potential role of the FXR in a rat model of SBS. Low expressions of FXR-related molecules were observed on the small intestine of SBS rats, along with increased proinflammatory factors and damaged barrier function. Furthermore, SBS rats possessed significantly decreased body weight and elevated death rate. Supplementation with OCA mitigated the damaged intestinal barrier and increased proinflammatory factors in SBS rats, accompanied by activated FXR-related molecules. Using 16S rDNA sequencing, the regulatory role of OCA on gut microbiota in SBS rats was witnessed. LPS stimulation to Caco-2 cells induced apoptosis and overexpression of proinflammatory factors in vitro. OCA incubation of LPS-pretreated Caco-2 cells activated FXR-related molecules, increased the expressions of TJPs, ameliorated apoptosis and inhibited overexpression of proinflammatory factors. CONCLUSIONS OCA supplementation could effectively ameliorate the intestinal barrier disruption and inhibit overexpression of proinflammatory factors in a rat model of SBS and LPS-pretreated Caco-2 cells. As a selective activator of FXR, OCA might realize its protective function through FXR activation.

Pharmacokinetics and Tolerability of a Single Dose of Apraglutide, a Novel, Long-Acting, Synthetic glucagon-like peptide-2 Analog With a Unique Pharmacologic Profile, in Individuals With Impaired Renal Function. J Clin Pharmacol 2024; 64:744-754. [PMID: 38465515 DOI: 10.1002/jcph.2423] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2023] [Accepted: 01/18/2024] [Indexed: 03/12/2024]
Abstract
Renal impairment is a common complication in patients with short bowel syndrome with intestinal failure (SBS-IF). Glucagon-like peptide-2 analogs, such as apraglutide, have been developed as a treatment option for SBS-IF. This study assessed the potential for apraglutide overexposure in individuals with severely impaired renal function versus healthy volunteers with normal renal function. In this phase 1, open-label, multicenter, nonrandomized, parallel-group study, a single dose of apraglutide 5 mg was administered subcutaneously to individuals with severely impaired renal function (<30 mL/min/1.73 m2) and healthy volunteers with normal renal function (≥90 mL/min/1.73 m2). Primary pharmacokinetic endpoints were maximum observed concentration (Cmax) and exposure to apraglutide (area under the curve [AUC] from time 0 to infinity [AUCinf], and AUC from time 0 to the last quantifiable concentration [AUClast]). Each group comprised 8 individuals. Results show that patients with severe renal impairment do not have increased apraglutide exposure. Apraglutide achieved a lower Cmax and AUCinf in individuals with severe renal impairment versus those with normal renal function (Cmax = 36.9 vs 59.5 ng/L; AUCinf = 3100 vs 4470 h · ng/mL, respectively). The respective geometric mean ratios were 0.620 and 0.693 for Cmax and AUCinf, and the upper bound of their 90% confidence intervals were <2, indicating patients with severe renal impairment were not overexposed to apraglutide versus those with normal renal function. Adverse events were mild or moderate in severity. Apraglutide does not require dose reduction for any degree of renal impairment and could be used in a broader patient population of renally impaired patients without dose adjustment.

Cost-effectiveness of teduglutide in adult patients with short bowel syndrome - a European socioeconomic perspective. Am J Clin Nutr 2024; 119:1187-1199. [PMID: 38431119 DOI: 10.1016/j.ajcnut.2024.02.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2023] [Revised: 02/22/2024] [Accepted: 02/28/2024] [Indexed: 03/05/2024] Open
Abstract
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.

Long-term outcomes and adverse effects of teduglutide in patients with short bowel syndrome: Highlighting hyperamylasemia and hyperlipasemia. Am J Health Syst Pharm 2024; 81:146-152. [PMID: 37941451 DOI: 10.1093/ajhp/zxad274] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Indexed: 11/10/2023] Open
Abstract
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. Nutr Clin Pract 2024; 39:141-153. [PMID: 37294295 DOI: 10.1002/ncp.11015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Revised: 03/24/2023] [Accepted: 04/24/2023] [Indexed: 06/10/2023] Open
Abstract
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.

Abstract
BACKGROUND Oral drug therapy may be compromised in chronic intestinal failure (IF) because of alterations in absorption and transit. Only scarce literature is available on which medication patients with chronic IF take in daily life. The aim was to describe the medication use in these patients. METHODS A medication history was obtained from adults with chronic IF treated in our tertiary care IF center. Degree of polypharmacy, drug classes, Biopharmaceutics Classification System classes, route of administration, and formulation of drugs were analyzed. RESULTS From October 2019 until December 2020, 72 patients (35 patients with short bowel syndrome [SBS] and 37 patients without SBS) were included. Polypharmacy was seen in 85.7% of patients with SBS and 75.7% of patients without SBS. The top three drug classes were proton-pump inhibitors, vitamin D or acetaminophen, and antimotility medication or laxatives/benzodiazepines. Approximately 25% of the drugs were classified as Biopharmaceutics Classification System class I drugs. In patients with SBS (78%) and patients without SBS (74.9%), most medication was taken orally, requiring gastrointestinal absorption of the active substance to be pharmacologically active. Most of these medications (77% in patients with SBS and 80.8% in patients without SBS) were formulated as a capsule or tablet, requiring disintegration and dissolution in the gastrointestinal tract before absorption can take place. CONCLUSION Polypharmacy was observed in most patients with chronic IF. Most medication was taken orally in formulations requiring disintegration, dissolution, and gastrointestinal absorption, which could be compromised in chronic IF.

Abstract
Short bowel syndrome (SBS) following extensive intestinal resection is often characterized by impaired absorption of orally administered drugs, including tyrosine kinase inhibitors (TKI). We report the case of a patient with EGFR-mutated non-small cell lung carcinoma treated with 80 mg/day of the TKI osimertinib who achieved partial response of the tumour, but was subsequently subjected to a double-barrelled jejunostomy due to ileus. Due to the development of SBS after the bypass surgery, plasma concentrations of osimertinib were monitored using mass spectrometry. The therapeutic drug monitoring confirmed a malabsorption of osimertinib in the patient (108 ng/mL, which is below the 5th percentile of the expected plasma concentration) and was useful to guide adjustments of TKI dosing in order to achieve adequate blood levels (161 ng/mL after increase of the dose to 120 mg/day) in order to maintain tumour control.

Abstract
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.

Abstract
OBJECTIVES This post-hoc analysis evaluated the effect of teduglutide treatment on diarrhea in patients with short bowel syndrome-associated intestinal failure (SBS-IF). METHODS Data from 2 open-label, multicenter, phase 3 pediatric SBS-IF clinical trials of teduglutide (NCT01952080 and NCT02682381) were pooled where possible. The primary objective was to evaluate the change in stool consistency, frequency, and volume from baseline to weeks 12 and 24 of treatment in patients who received any teduglutide dose from both studies ("total teduglutide"). Safety assessments included gastrointestinal adverse event reporting. RESULTS Overall, 101 patients were analyzed. Among the total teduglutide group (n = 87), there were significant changes from baseline to weeks 12 and 24 in mean (standard error) Bristol Stool Form Scale (BSFS) score [-1.8 (0.26; P < 0.0001) and -2.2 (0.27; P < 0.0001), respectively], parenteral nutrition and/or intravenous fluid (PN/IV) volume [-16.9 (1.7; P < 0.0001) and -20.1 (2.3; P < 0.0001) mL/kg/day, respectively], and enteral nutrition volume [9.2 (1.7; P < 0.0001) and 9.6 (2.3; P = 0.0002) mL/kg/day, respectively]. Among patients in the standard of care group (n = 14) there were numerical changes in BSFS score, and enteral nutrition volume at weeks 12 and 24; significant changes in PN/IV volume [-6.9 (1.5) mL/kg/day; P = 0.0041] were observed at 24 weeks, but not at 12 weeks. CONCLUSION In this post-hoc analysis, short-term treatment with teduglutide was associated with improved stool consistency, as well as trends towards reductions in PN/IV requirements and advancements in enteral nutrition volume in children with SBS-IF. Further research assessing the impact of patient-level factors on stool characteristics when using teduglutide is warranted.

Abstract
BACKGROUND Enteral drug therapy is challenging in short bowel syndrome with intestinal failure (SBS-IF) because of unpredictable absorption. SEFA-6179 is an enterally administered medium-chain fatty acid analogue under development for intestinal failure-associated liver disease. We investigate the pharmacokinetics of two SEFA-6179 formulations in two large-animal models of SBS-IF, including a new pseudojejunostomy model. METHODS Twenty Yucatan minipigs were obtained. Half underwent pre-resection pharmacokinetic study with single-dose SEFA-6179 administration. All minipigs then underwent 90% jejunoileal resection, with either a jejunoileal anastomosis or bypass of the intraperitoneal colon with anastomosis just proximal to the rectum (pseudojejunostomy). On postoperative day 3, a single-dose pharmacokinetic study was performed. RESULTS Both SBS-IF models were well tolerated. Compared with the jejunoileal anastomosis minipigs, pseudojejunostomy minipigs had a more severe malabsorptive phenotype with weight loss by postoperative day 4 (+0.1 vs -0.9 kg, P = 0.03) and liquid diarrhea (Bristol 5 vs Bristol 7, P = 0.0007). Compared with pre-resection minipigs, both jejunoileal and pseudojejunostomy minipigs had lower total plasma exposure of SEFA-6179 measured by area under the curve (jejunoileal: 37% less, P = 0.049; pseudojejunostomy: 74% less, P = 0.0001). Peak plasma concentration was also lower in the pseudojejunostomy group compared with pre-resection (65% less, P = 0.04), but not lower in the jejunoileal group (P = 0.47). CONCLUSION In two SBS-IF minipig models, SEFA-6179 had substantially decreased absorption compared with pre-resection minipigs. Dose optimization for different intestinal anatomy and function may be required. We describe a new SBS-IF pseudojejunostomy model that may improve the translation of preclinical research to patients with SBS-IF who have enterostomies.

Abstract
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.

Abstract
OBJECTIVES Our objective was to evaluate the short- and long-term safety and efficacy of teduglutide treatment in infants and children with short bowel syndrome with intestinal failure (SBS-IF). METHODS Two open-label phase 3 studies and 1 extension study investigated the short- and long-term safety and efficacy of teduglutide (0.05 mg/kg/day) in infants and children with SBS-IF: NCT03571516, 24-week study of infants who were randomized to receive teduglutide or standard of care (SoC); NCT02980666, 24-week study of infants and children who all received teduglutide; and NCT03268811, 24-week extension study of patients who completed NCT02980666 (patients could receive up to 48 weeks of total treatment). RESULTS Twelve infants and 8 children enrolled in the core studies, and 2 infants and 7 children in the extension study. After 24 weeks of treatment, parenteral support (PS) requirements reduced by ≥20% from baseline for 4 infants (57.1%) and 4 children (66.7%) receiving teduglutide and for 2 infants receiving SoC (50.0%). One infant (50.0%) and 4 children (80.0%) receiving teduglutide maintained the ≥20% reduction in PS at 48 weeks of treatment. Two children receiving teduglutide achieved enteral autonomy, after 12 weeks and 28 weeks of treatment, respectively. All adverse events (AEs) were in line with known impacts of SBS-IF and adverse reactions to teduglutide. Only one serious AE (abdominal pain) was considered related to teduglutide. CONCLUSIONS Short- and long-term treatment with teduglutide resulted in clinically meaningful reductions in PS requirements for infants and children with SBS-IF. Teduglutide was well tolerated, and efficacy improved with longer-term treatment.

Abstract
INTRODUCTION There is limited guidance on the selection of tyrosine kinase inhibitors (TKIs) in patients with short bowel syndrome (SBS). Concerns regarding absorption, toxicity profiles, and drug interactions should be considered when selecting optimal TKI therapy. CASE REPORT A 57-year-old male with SBS was newly diagnosed with chronic myeloid leukemia (CML). A careful review of his surgical history, comorbidities, and concurrent medications led to a treatment decision to initiate dasatinib at 100 mg once daily. MANAGEMENT AND OUTCOME After initiation of therapy, the patient achieved a complete hematological response after two weeks and an early major molecular response on a three-month assessment. The therapy was tolerated well with no identified adverse effects. DISCUSSION Clinical rationale for selecting dasatinib in patients with SBS includes supporting literature regarding its pharmacokinetic absorption characteristics, its efficacy with lower doses in newly diagnosed patients with CML, and its side effect profile in comparison to other second-generation TKIs. The case discussed provides an example of successful therapy in a patient with SBS undergoing treatment for CML.

Abstract
Introduction 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.

Short-term clinical evaluation of teduglutide for patients with Crohn’s disease on home parenteral support for postoperative short bowel syndrome with intestinal failure. Clin Nutr 2023; 42:722-731. [PMID: 37001195 DOI: 10.1016/j.clnu.2023.03.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 03/10/2023] [Accepted: 03/12/2023] [Indexed: 03/19/2023]
Abstract
BACKGROUND & AIM The short-term effects of teduglutide (TED) for short bowel syndrome with chronic intestinal failure (SBS-IF) in patients with Crohn's disease (CD) remain unknown. The aim of this study was to investigate the effects of TED in patients with CD on home parenteral support (PS) for SBS-IF. METHODS We retrospectively investigated the medical records of patients with CD associated with SBS-IF who initiated TED between 2020 and 2021. The primary outcomes were the change in PS volume and proportion of patients with a reduction of PS volume by ≥ 20% at week 8. Secondary outcomes were the change in PS volume in patients with CD without/with colon in continuity and adverse events during the observation period. RESULTS Eighteen patients with CD who underwent home PS for SBS-IF were included in this study. Two patients were excluded owing to intolerable abdominal pain or vomiting within 8 weeks (11%). Sixteen patients continued TED throughout the observation period. The median PS duration was 10.5 years. The median observation period was 22 weeks after starting TED. TED significantly reduced the PS volume from 15,825.0 mL/week to 10,700.0 mL/week (p = 0.0038), and the PS volume decreased by ≥ 20% in 7 patients (43.8%) at week 8. The PS volume was significantly reduced at week 4 (p = 0.0078) in 11 patients without colon in continuity but not in 5 patients with colon in continuity. Two patients successfully stopped home PS. No serious adverse events occurred. CONCLUSIONS TED administration significantly reduced PS volume at week 8 in patients with CD associated with SBS-IF, and at week 4 in patients without colon in continuity.

Abstract
Short bowel syndrome (SBS) with intestinal failure (IF) is a rare but severe complication of Crohn’s disease (CD), which is the most frequent benign condition that leads to SBS after repeated surgical resections, even in the era of biologics and small molecules. Glucagon-like peptide-2 analogues have been deeply studied recently for the treatment of SBS-IF. These drugs have a significant intestinotrophic effect and the potential to reduce the chronic dependence of SBS-IF patients on parenteral support or nutrition. Teduglutide has been approved for the treatment of SBS-IF, and apraglutide is currently in clinical development. The use of these drugs was examined with a focus on their use in CD patients.

Abstract
Teduglutide (Revestive®, 10 mg mL-1) is a recombinant human glucagon-like peptide 2 analogue, used in the treatment of short bowel syndrome, a serious and highly disabling condition which results from either too small a length of intestine or loss of critical intestinal function. The determination of therapeutic compounds of protein-nature is always challenging due to their complex structure. In this work, we present a fast, straightforward reversed phase (RP)UHPLC-UV-(HESI/ORBITRAP)MS method for the identification and quantification of the intact teduglutide peptide. The method has been developed and validated in accordance with the International Council for Harmonization of Technical Requirements for Pharmaceuticals for Human Use (ICH) guidelines; therefore, linearity, limits of detection and quantification, accuracy (precision and trueness), robustness, system suitability and specificity using the signal from the UV and MS, have been evaluated. The validation performance parameters obtained from the UV and MS signals were compared throughout the work, to select the most suitable. To study the specificity of the method and the impact of medicine mishandling under hospital conditions, force degradation studies were performed, i.e. thermal (40 °C and 60 °C), shaking (mechanical) and light (accelerated exposition) effects. Identification by the exact mass of teduglutide was achieved and it was confirmed that the peptide does not undergo any post-translational modifications (PTMs). To the best of our knowledge, the present work reports the first method developed for the simultaneous identification, structural characterization, and quantification of the therapeutic teduglutide peptide. Finally, the proposed method is able to indicate stability when quantifying the intact teduglutide since detects and characterises the exact mass of the degradation/modification products.

Tracking the physicochemical stability of teduglutide (Revestive®) clinical solutions over time in different storage containers. J Pharm Biomed Anal 2022; 221:115064. [PMID: 36152491 DOI: 10.1016/j.jpba.2022.115064] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2022] [Revised: 09/12/2022] [Accepted: 09/15/2022] [Indexed: 11/20/2022]
Abstract
Teduglutide, the active ingredient of the medicine Revestive® (5 mg), is a recombinant therapeutic peptide that mimics the effects of the endogenous glucagon-like peptide 2 (GLP-2). It stimulates intestinal growth, adaptation and function in patients with Short Bowel Syndrome who are dependent on parenteral nutrition. The Summary of Product Characteristics recommends immediate use of the reconstituted solutions and the discarding of any subsequent surplus. This study aims to carry out a long-term stability study that reproduces hospital conditions of use which provide sound evidence regarding the use of teduglutide surplus beyond the Summary Product Characteristics recommendations. We conducted a stability study of teduglutide solutions prepared from a 5 mg vial of Revestive®. Some of the solutions were stored in their original vial after reconstitution, while others were repackaged in plastic syringes to evaluate their physicochemical stability over time. For this purpose, we applied a set of previously validated analytical methodologies to evaluate the main critical quality attributes of teduglutide, i.e., primary (including post-tralational modifications), secondary and tertiary structures, aggregates, particulate, concentration and pH. The results indicate that the solutions maintain high physicochemical stability over time, regardless of the storage temperature (4ºC or -20ºC) or the storage container (vials or syringes). This research provides new data on the stability of Revestive® that will be of great value to hospital pharmacists. This comprehensive assessment of the physicochemical long-term stability of TGT has demonstrated that under the storage conditions and over the period studied here, the medicine maintains its quality, efficacy and safety profiles.

Abstract
Panitumumab, a fully human anti-epidermal growth factor receptor (EGFR) monoclonal antibody, has been shown to be useful in treating either advanced or recurrent KRAS/NRAS/BRAF wild-type colorectal cancer. We herein report the case of a 60-year-old man with short bowel syndrome who developed hematochezia due to panitumumab-induced colitis with vitamin K deficiency during third-line chemotherapy. The cause of vitamin K deficiency was the lack of intravenous vitamin K supplementation following a change from central venous nutrition to peripheral venous nutrition. We advise clinicians to carefully check for colitis and manage the infusions of chemotherapy patients with short bowel syndrome.

Abstract
INTRODUCTION In patients with short bowel syndrome (SBS), severe malabsorption may cause a need for parenteral support and, by definition, these patients suffer from SBS intestinal failure. Absorption of oral medications is likely diminished in patients with SBS intestinal failure and higher than normal doses may be required to achieve sufficient pharmacologic effect. We investigated the prescription patterns and oral dosages in a well-defined population of patients with non-malignant SBS intestinal failure. METHODS This was a cross-sectional analysis based on a cohort of adult patients with SBS intestinal failure treated with home parenteral support and registered in 2016 at the Department of Gastroenterology at the Copenhagen University Hospital - Rigshospitalet. The patients' clinical data and prescription patterns were extracted from electronic medical and medications records. RESULTS The patients in our cohort (n = 74) were primarily females (58%), the median age was 63 years (interquartile range (IQR): 52-72 years) and the median BMI was 22 kg/m2 (IQR: 19-26 kg/m2). Each patient was treated with a median of eight drugs (range: 1-20). Most (75%) of the medications were administered orally. Only codeine, levothyroxine and loperamide were prescribed in higher dosages than recommended in their product labelling. All medication-treated patients were prescribed between one and four different analgesics. CONCLUSION In our single-centre cohort of patients with SBS intestinal failure, orally administered medications were generally prescribed in recommended dosages. FUNDING none Trial registration. Approved by the Danish Data Protection Agency (BFH-2016-058, I-Suite no.: 04906) and the Danish Patient Safety Authority (3-3013-1884/1/).

Changes in Parenteral Nutrition Requirements and BMI in Patients with Parenteral Nutrition-Dependent Short Bowel Syndrome after Stopping Teduglutide-9 Years of Follow-Up. Nutrients 2022; 14:nu14081634.

Abstract
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.

Abstract
PURPOSE OF REVIEW Short bowel syndrome (SBS) patients are at risk to develop intestinal failure when the decreased absorption of macronutrients, water, and electrolytes necessitates parenteral support for survival. The adverse effects of SBS and parenteral support negatively affect the quality of life (QoL) of SBS-intestinal failure patients. However, spontaneous intestinal adaptation along with disease-modifying therapies allow reducing parenteral support, thereby improving QoL. RECENT FINDINGS During the first years following extensive surgery, spontaneous structural and functional intestinal changes take place which stimulate a more efficient nutrient and fluid absorption in the remaining bowel. Given their potential role in the ileal braking mechanism, enterohormones, such as glucagon-like peptide (GLP)-2, GLP-1, and peptide YY (PYY), promote an accelerated adaptation or hyperadaptation. While the exact role of GLP-1 and PYY in SBS is still being explored, GLP-2 analogs have clearly shown to be effective in improving outcome in SBS. SUMMARY Whereas spontaneous intestinal adaptation improves the nutritional status of SBS patients to a certain extent, GLP-2 analogs can further decrease parenteral support needs through hyperadaptation. There are, however, other promising candidates on the horizon that - alone or in combination - could possibly establish additional disease-modifying effects.

Abstract
PURPOSE OF REVIEW Intestinal failure (IF) evolved from being the last recognized organ failure, to become one of the most progressive fields in terms of therapeutic alternatives and results. Short bowel syndrome (SBS) is the main cause of IF in adults and children. The use of surgery allowed patients with unfavorable anatomy type and length to be wean off parenteral nutrition. We aim to evaluate its current impact on intestinal rehabilitation. RECENT FINDINGS Autologous gastro-intestinal reconstructive surgery (AGIRS), including bowel lengthening contributes by converting patient's anatomy to a more favorable one, improving quality of life, and modifying the natural history of the disease, allowing to recover intestinal autonomy in approximately 70% of the adults and 50% of the children's with SBS-IF. The current use of postsurgical medical rehabilitation strategies including the use of enterohormones complement the path to sufficiency, increasing the chances of success in both age group of patients. SUMMARY The development of AGIRS has changed the outcome of SBS-IF patients, becoming the main surgical procedure prescribed in multidisciplinary units, allowing to enhance the number of patients achieving intestinal autonomy throughout rehabilitation, leaving transplantation as the last surgical alternative.

Efficacy of Teduglutide for Parenteral Support Reduction in Patients with Short Bowel Syndrome: A Systematic Review and Meta-Analysis. Nutrients 2022; 14:nu14040796.

Abstract
Teduglutide has been described as an effective treatment for parenteral support (PS) reduction in patients with short bowel syndrome (SBS). However, a quantitative summary of the available evidence is still lacking. PubMed/Medline, EMBASE, Cochrane library, OVID, and CINAHL databases were systematically searched up to July 2021 for studies reporting the rate of response (defined as a ≥20% reduction in PS) to teduglutide among PS-dependent adult patients. The rate of weaning (defined as the achievement of PS independence) was also evaluated as a secondary end-point. Ten studies were finally considered in the meta-analysis. Pooled data show a response rate of 64% at 6 months, 77% at 1 year and, 82% at ≥2 years; on the other hand, the weaning rate could be estimated as 11% at 6 months, 17% at 1 year, and 21% at ≥2 years. The presence of colon in continuity reduced the response rate (-17%, 95%CI: (-31%, -3%)), but was associated with a higher weaning rate (+16%, 95%CI: (+6%, +25%)). SBS etiology, on the contrary, was not found to be a significant predictor of these outcomes, although a nonsignificant trend towards both higher response rates (+9%, 95%CI: (-8%, +27%)) and higher weaning rates (+7%, 95%CI: (-14%, +28%)) could be observed in patients with Crohn's disease. This was the first meta-analysis that specifically assessed the efficacy of teduglutide in adult patients with SBS. Our results provide pooled estimates of response and weaning rates over time and identify intestinal anatomy as a significant predictor of these outcomes.

Intestinal iatrogenic hyperadaptation in patients with short bowel syndrome and Crohn's disease: Is this an indication for mandatory lifelong injections of teduglutide? Nutrition 2021; 91-92:111396.

Abstract
Short bowel syndrome with chronic intestinal failure (SBS-CIF) is a rare disease leading to a markedly decreased absorption of fluids and nutrients. Intestinal adaptation in patients with SBS-CIF who are treated with home parenteral nutrition is a natural repair process activated by increased secretions of glucagon-like peptide-2, inducing intestinal trophism, nutrient transport, and lowering gastrointestinal motility. Teduglutide (TED), a glucagon-like peptide-2 analog, offers a new, effective therapeutic alternative to boost intestinal adaptation. There is still no consensus regarding the question of whether intestinal adaptation is permanent or a transient, drug-dependent process requiring lifelong injections of TED. Here we report the clinical cases of two female patients with SBS-CIF secondary to Crohn's disease, who had received TED for 36 and 41 mo. In both patients, TED was discontinued for 5 d but needed to be resumed after an additional 5 d. In patient 1, the discontinuation of TED was accidental (the patient inadvertently injected frozen TED vials); whereas in patient 2, the suspension was at the patient's request. A rapid, significant (P < 0.0001) decline of intestinal function (diarrheal evacuations, fecal volume, food intake) was documented after the suspension of active TED in patient 1. After the resumption of active TED, the symptoms rapidly and significantly (P < 0.0001) improved. The same trend was observed in patient 2. Infective causes of diarrhea were ruled out in both patients. In conclusion, our experience shows that even after long-term treatment, the iatrogenic hyperadaptation process obtained with TED results is a temporary, drug-dependent process and vanishes with the suspension of therapy. These clinical cases suggest that in patients with SBS-CIF receiving TED, this treatment must be administered lifelong.

Sitagliptin, a dipeptidyl peptidase-4 inhibitor, in patients with short bowel syndrome and colon in continuity: an open-label pilot study. BMJ Open Gastroenterol 2021; 8:e000604.

Abstract
OBJECTIVE Patients with short bowel syndrome (SBS) and colon in continuity have better adaptation potential compared with patients with jejunostomy. Adaptation may involve enhanced postprandial secretion of the enteroendocrine hormones glucagon-like peptide (GLP)-1 and GLP-2 which are normally degraded by dipeptidyl peptidase (DPP)-4. Nevertheless, some patients with SBS with colon in continuity suffer from high-volume faecal excretions and have been shown to benefit from treatment with GLP-2. Therefore, we aimed to evaluate efficacy of sitagliptin, a DPP-4 inhibitor, on reducing faecal excretions in this patient group. DESIGN In an open-label, case series, proof-of-concept pilot study, 100 mg oral sitagliptin was given two times per day for 8 weeks to patients with SBS with ≥50% colon in continuity with or without the need for parenteral support (PS). To assess intestinal function, metabolic balance studies were done at baseline and following 8 weeks of treatment. RESULTS Of the 10 patients planned for enrolment, 8 patients were included; 7 patients completed the study. Although postprandial endogenous GLP-2 concentrations increased by 49 hours×pmol/L (39, 105; p=0.018) (median (min, max)), sitagliptin did not significantly reduce median faecal wet weight (-174 g/day (-1510, 675; p=0.176)) or increase intestinal wet weight absorption. However, heterogeneity in the treatment effect was observed: intestinal wet weight absorption increased in all four patients with intestinal failure. One patient achieved a reduction in PS by 500 mL per administration day. CONCLUSION Following this negative, small pilot study, larger, placebo-controlled, studies are needed to establish the therapeutic potential of DPP-4 inhibition in patients with SBS.

Abstract
A 40-year-old man suffered from short bowel syndrome. Since a large amount of intestinal output and watery diarrhea hampered his quality of life, we tried to control the intestinal output by reducing the secretion of gastric acid with lansoprazole. Because the small intestine was only 10 cm in length and effective absorption of oral lansoprazole was doubtful, we monitored his intragastric pH for 24 hours and confirmed that the holding time above pH 3.0 was 14.5 hours (60.4%). He spent his home life eating porridge during the day, and receiving total parenteral nutrition of 1,100 mL/day at night while taking lansoprazole as an oral tablet (30 mg) once a day.

Ghrelin stimulates intestinal adaptation following massive small bowel resection in parenterally fed rats. Peptides 2018; 106:59-67.

Abstract
BACKGROUND Since short bowel syndrome (SBS) patients face life-threatening conditions, the development of therapeutic strategies to induce intestinal adaptation has been investigated. Ghrelin, a ligand of growth hormone (GH) secretagogue-receptor that stimulates the release of GH and insulin like growth factor-1 (IGF-1), has several pleiotropic effects. We investigated whether ghrelin induces intestinal adaptation in parenterally fed rats with SBS. METHODS Sprague-Dawley rats underwent venous catheterization and were divided into 3 groups: those receiving 90% small bowel resection while leaving the proximal jejunum and distal ileum (90% SBR) with TPN (SBS/TPN group), those receiving 90% SBR with TPN + ghrelin (SBS/TPN/ghrelin group), and those receiving sham operation and fed chow (sham group). Ghrelin was administered intravenously at 10 μg/kg/day. On Day 13, the rats were euthanized and the small intestine harvested, and the histology and crypt cell proliferation rates (CCPR), apoptosis, and nutrient transporter protein levels were analyzed and the plasma hormones were measured. RESULTS The villus height and crypt depth of the ileum in the SBS/TPN/ghrelin group were significantly higher than in the SBS/TPN group. The CCPR of the jejunum and the ileum significantly increased by the administration of ghrelin; however, the apoptosis rates did not significantly differ between the SBS/TPN and SBS/TPN/ghrelin groups. Significant differences did not exist in the plasma IGF-1 and nutrient transporter protein levels among three groups. CONCLUSIONS The intravenous administration of ghrelin stimulated the morphological intestinal adaptation of the ileum to a greater degree than the jejunum due to the direct effect of ghrelin.

Abstract
RATIONALE Saccharated ferric oxide has been shown to lead to elevation of fibroblast growth factor 23, hypophosphatemia, and, consequently, osteomalacia. Moreover, mineral imbalance is often observed in patients with short-bowel syndrome to some degree. PATIENT CONCERNS A 62-year-old woman with short-bowel syndrome related with multiple resections of small intestines due to Crohn disease received regular intravenous administration of saccharated ferric oxide. Over the course of treatment, she was diagnosed with tetany, which was attributed to hypocalcemia. Additional assessments of the patient revealed not only hypocalcemia, but also hypophosphatemia, hypomagnesemia, osteomalacia, and a high concentration of fibroblast growth factor 23 (314 pg/mL). DIAGNOSES We diagnosed her with mineral imbalance-induced osteomalacia due to saccharated ferric oxide and short-bowel syndrome. INTERVENTIONS Magnesium replacement therapy and discontinuation of saccharated ferric oxide alone. OUTCOMES These treatments were able to normalize her serum mineral levels and increase her bone mineral density. LESSONS This case suggests that adequate evaluation of serum minerals, including phosphate and magnesium, during saccharated ferric oxide administration may be necessary, especially in patients with short-bowel syndrome.

Abstract
Extensive resection of the intestinal tract with resulting malabsorption is known as short bowel syndrome (SBS). Adaptation and rehabilitation of the remaining small bowel occurs spontaneously after resection and can be enhanced by diet, medications, and use of intestinal trophic factors such as recombinant human growth hormone (r-hGH). Many trials have been published on the influence of r-hGH therapy in SBS patients, with varying results. Analysis of the trials has produced a set of criteria that can be used to define the patient most likely to benefit from r-hGH therapy.

Intestinal adaptation in proximal and distal segments: Two epithelial responses diverge after intestinal separation. Surgery 2016; 161:1016-1027. [PMID: 28011012 DOI: 10.1016/j.surg.2016.10.033] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2016] [Revised: 09/30/2016] [Accepted: 10/20/2016] [Indexed: 02/07/2023]
Abstract
BACKGROUND In short bowel syndrome, luminal factors influence adaptation in which the truncated intestine increases villus lengths and crypt depths to increase nutrient absorption. No study has evaluated the effect of adaptation within the distal intestine after intestinal separation. We evaluated multiple conditions, including Igf1r inhibition, in proximal and distal segments after intestinal resection to evaluate the epithelial effects of the absence of mechanoluminal stimulation. METHODS Short bowel syndrome was created in adult male zebrafish by performing a proximal stoma with ligation of the distal intestine. These zebrafish with short bowel syndrome were compared to sham-operated zebrafish. Groups were treated with the Igf1r inhibitor NVP-AEW541, DMSO, a vehicle control, or water for 2 weeks. Proximal and distal intestine were analyzed by hematoxylin and eosin for villus epithelial circumference, inner epithelial perimeter, and circumference. We evaluated BrdU+ cells, including costaining for β-catenin, and the microbiome was evaluated for changes. Reverse transcription quantitative polymerase chain reaction was performed for β-catenin, CyclinD1, Sox9a, Sox9b, and c-Myc. RESULTS Proximal intestine demonstrated significantly increased adaptation compared to sham-operated proximal intestine, whereas the distal intestine showed no adaptation in the absence of luminal flow. Addition of the Igf1r inhibitor resulted in decreased adaption in the distal intestine but an increase in distal proliferative cells and proximal β-catenin expression. While some proximal proliferative cells in short bowel syndrome colocalized β-catenin and BrdU, the distal proliferative cells did not co-stain for β-catenin. Sox9a increased in the distal limb after division but not after inhibition with the Igf1r inhibitor. There was no difference in alpha diversity or species richness of the microbiome between all groups. CONCLUSION Luminal flow in conjunction with short bowel syndrome significantly increases intestinal adaption within the proximal intestine in which proliferative cells contain β-catenin. Addition of an Igf1r inhibitor decreases adaptation in both proximal and distal limbs while increasing distal proliferative cells that do not colocalize β-catenin. Igf1r inhibition abrogates the increase in distal Sox9a expression that otherwise occurs in short bowel syndrome. Mechanoluminal flow is an important stimulus for intestinal adaptation.

Abstract
Objective: To summarize the pharmacology, development, and clinical application of teduglutide (ALX-0600), a glucagon-like peptide-2 (GLP-2) analog for the treatment of short bowel syndrome (SBS). Data Sources: Clinical literature, including both primary sources and review articles, was accessed through a search of the MEDLINE databases (1980–March 2006). Key search terms included teduglutide, ALX-0600, glucagon-like peptide-2, short bowel syndrome, short gut, and intestinal adaptation. Clinical trial and drug data were supplied by the manufacturer, NPS Pharmaceuticals. Study Selection and Data Extraction: Review articles, abstracts, and clinical studies related to GLP-2 and its analog, teduglutide, were analyzed. An evaluation of the research exploring teduglutide for the management of SBS was conducted. Relevant information was then selected. Data Synthesis: Research has revealed that administration of GLP-2 to patients following major small bowel resection improves intestinal adaptation and nutrient absorption. Teduglutide is an enzyme-resistant GLP-2 analog that shows promise in preventing intestinal injury, restoring mucosal integrity, and enhancing intestinal absorptive function. Conclusions: Data from ongoing clinical trials indicate that teduglutide may have the ability to enhance intestinal absorptive capacity in patients with SBS. Further studies and the completion of Phase III trials are necessary to determine the appropriate dosage and length of treatment for patients with SBS to gain optimal therapeutic benefit from this drug.

Abstract
Teduglutide (Gattex(®)) is a recombinant analogue of human glucagon-like peptide-2 and is indicated for the treatment of adults with short bowel syndrome (SBS) dependent on parenteral support (PS). In a pivotal, 24-week clinical trial in SBS patients, subcutaneous teduglutide 0.05 mg/kg once daily increased absorption from the remnant intestine as evidenced by significant reductions in PS volume requirements versus placebo. Improvements attained in absorption in the first 6 months of therapy were maintained during the extension trial (total teduglutide treatment periods of up to 30 months), with evidence indicating that benefits accrue over time. Among patients who received teduglutide treatment for up to 30 months, 11 of 30 were able to achieve at least one additional day off PS and another ten achieved complete independence from PS. Subcutaneous teduglutide was generally well tolerated in clinical trials, including over the long term, with most adverse events that led to study discontinuation being gastrointestinal in origin.

Abstract
The use of somatostatin to manage diarrhea associated with the short gut syndrome is impractical because of its need to be given by continuous infusion and a rebound effect on stool output with cessation of therapy. Octreotide has been used more successfully to control stool and electrolyte losses in patients with shortened gastrointestinal tracts. In published series and studies, all subjects appear to decrease stool losses, but clinical benefit for long-term use is not achieved for all patients. In the patients who do respond, the need for parenteral nutrition and intravenous hydration has been decreased or eliminated. The optimal dose is unclear, but many patients respond to 50-micrograms injections twice daily. Several investigations noted no additional beneficial effects with escalating dosages. Adverse effects include impairment of fat absorption, which may offset the therapeutic benefits of octreotide. The patients with the greatest response appear to have the least fat malabsorption. Other adverse effects noted when using octreotide for control of the short gut syndrome include pain associated with subcutaneous injection and abdominal complaints. Other potential concerns include the effect on gallstone formation in this high-risk population and intestinal adaptation.

Abstract
PURPOSE OF REVIEW The approval of teduglutide, a recombinant analog of human glucagon-like peptide (GLP) 2, by the US Food and Drug Administration (Gattex) and the European Medicines Agency (Revestive) has illustrated the potential of selected gut hormones as treatments in patients with short-bowel syndrome and intestinal failure. Gut hormones may improve the structural and functional intestinal adaptation following intestinal resection by decreasing a rapid gastric emptying and hypersecretion, by increasing the intestinal blood flow, and by promoting intestinal growth. This review summarizes the findings from phase 2 and 3 teduglutide studies, and pilot studies employing GLP-1 and agonists for this orphan condition. RECENT FINDINGS In a 3-week, phase 2, metabolic balance study, teduglutide increased the intestinal wet weight absorption by approximately 700 g/day and reduced fecal energy losses by approximately 0.8 MJ/day (∼200 Kcal/day). In two subsequent 24-week, phase 3 studies, teduglutide reduced the need for parenteral support in the same magnitude. Adverse events were mainly of gastrointestinal origin and consistent with the known mechanism of action of teduglutide. Pilot studies suggest that GLP-1 may be less potent. Synergistic effects may be seen by co-treatment with GLP-2. SUMMARY Gut hormones promote intestinal adaptation and absorption, decreasing fecal losses, thereby decreasing or even eliminating the need for parenteral support. This will aid the intestinal rehabilitation in these severely disabled short-bowel syndrome patients.

Abstract
BACKGROUND Short bowel syndrome is a disabling disease requiring long-term nutritional support and ancillary drugs. Aiming to analyze the most commonly prescribed drugs, a retrospective analysis was conducted is an outpatient cohort. PATIENTS AND METHODS Stable patients (N= 37, 59.5% males, age 51.1 ± 20.1 years, body mass index 20.1 ± 7.9 kg/m2) with three or more appointments in the Outpatient Service during the last 18 months were retrospectively analyzed. regarding oral pharmacologic prescriptions. Medications were classified as on label or off label. RESULTS A total of 257 oral prescriptions were retrieved from computer files, encompassing 17 different preparations. The majority was employed on label however 28.8% (74/257) were classified as off label and scrutinized with regard to indications. The main categories were pharmacologic modulators of gastrointestinal secretions and motility, along with antibiotics. Virtually all patients required one or more of such drugs, without differences regarding demographic or clinical variables. Adverse effects or premature drug discontinuation were not observed. CONCLUSIONS This is the first study to our knowledge highlighting the importance of adjuvant drugs, particularly with unconventional indications, in the management of short bowel syndrome. Antidiarrheic agents, pancrelipase micropellets, antacids and antibiotics represented the most relevant off label prescriptions for this population.

Abstract
By definition, intestinal failure prevails when oral compensation is no longer feasible and parenteral support is necessary to maintain nutritional equilibrium. In the past, conventional treatment has mainly focused on "making the most of what the short bowel syndrome patient still had" by optimizing remnant intestinal function through dietary interventions, antidiarrheals and antisecretory agents. However, modern treatment options are in the near horizon, and the increased understanding of the mediators for intestinal adaptation will lead to the expansion of the limited treatment armamentarium in short bowel syndrome patients with intestinal failure. The clinical meaningfulness and implications of the observed effects of growth hormone, glutamine, glucagon-like peptide 2 (GLP-2) and the dipeptidyl peptidase-4 degradation resistant analog, teduglutide, is presented in this review and balanced against treatment related adverse events and possible unfavourable effects of long-term, possibly lifelong, treatments.

Abstract
BACKGROUND Intestinal failure (IF) is the dependence upon parenteral nutrition to maintain minimal energy requirements for growth and development. It may occur secondary to a loss of bowel length, disorders of motility, or both. Short bowel syndrome (SBS) is a malabsorptive state resulting from surgical resection, congenital defect, or diseases associated with loss of absorptive surface area. A particularly vexing problem is associated with whole bowel and/or segmental intestinal dysmotility. Motility disorders within the context of SBS and IF may relate to rapid intestinal transit secondary to loss of intestinal length, dysmotility associated with loss or poor antegrade peristalsis, or gastroparesis. Therapy may be classified into medical (prokinetic and antidiarrheal agents) and surgical to deal with the overdistended poorly motile bowel. METHODS We performed a systematic review of the literature pertaining to IF, SBS, and dysmotility in the pediatric population with gastroschisis, necrotizing enterocolitis, and intestinal atresia. In addition to the available treatment options, we have provided a review of the literature and a summary of the available evidence. CONCLUSION Despite relatively poor level of evidence regarding the application of promotility and antidiarrheal medications in patients with SBS and IF, these agents continue to be used. Herein, we provide a review of the physiology and pathophysiology of intestinal motility/dysmotility and available strategies for the use of promotility and antidiarrheal agents in patients with IF/SBS.

Abstract
BACKGROUND Glucagon-like peptide-2 induces small intestine mucosal epithelial cell proliferation and may have benefit for patients who suffer from short bowel syndrome. However, glucagon-like peptide-2 is inactivated rapidly in vivo by dipeptidyl peptidase IV. Therefore, we hypothesized that selectively inhibiting dipeptidyl peptidase IV would prolong the circulating life of glucagon-like peptide-2 and lead to increased intestinal adaptation after development of short bowel syndrome. METHODS Eight-week old C57BL/6J mice underwent a 50% proximal small bowel resection and were treated with either sitagliptin, a dipeptidyl peptidase IV-inhibitor, starting 1 day before surgery versus placebo. The efficacy of dipeptidyl peptidase IV-inhibitor was assessed 3 days after resection, including intestinal morphology, epithelial cell apoptosis, and epithelial cell proliferation. Adaptive mechanisms were assessed with quantitative real-time polymerase chain reaction, and plasma bioactive glucagon-like peptide-2 was measured by radioimmunoassay. RESULTS Body weight loss and peripheral blood glucose levels did not change compared with short bowel syndrome controls. Dipeptidyl peptidase IV-inhibitor treatment led to significant increases in villus height and crypt depth. Dipeptidyl peptidase IV-inhibitor treatment did not change EC apoptosis rates significantly, but it did increase crypt epithelial cell proliferation significantly versus placebo-short bowel syndrome controls. Dipeptidyl peptidase IV-inhibitor treatment markedly increased messenger RNA expression of β-catenin and c-myc in ileal mucosa. Plasma glucagon-like peptide-2 levels increased significantly (∼ 40.9%) in dipeptidyl peptidase IV-inhibitor short bowel syndrome mice. CONCLUSION Dipeptidyl peptidase IV-inhibitor treatment increased short bowel syndrome adaptation and might potentially be useful for short bowel syndrome patients.

Abstract
BACKGROUND AND OBJECTIVES Gastrointestinal dysmotility is common in pediatric short-bowel syndrome, leading to prolonged parenteral nutrition dependence. There is limited literature regarding the safety and efficacy of cisapride for this indication. The aim of the study was to describe the safety and efficacy of cisapride for enteral intolerance in pediatric short-bowel syndrome. METHODS Open-labeled pilot study in a limited access program for cisapride. Indications were short-bowel syndrome with underlying dysmotility and difficulty advancing enteral feeds despite standard therapies and without evidence of anatomic obstruction. Patients received cisapride 0.1 to 0.2 mg/kg per dose for 3 to 4 doses per day. We collected electrocardiogram, nutrition, and anthropometric data prospectively at study visits. RESULTS Ten patients with mean (SD) age of 30.3 (30.5) months were enrolled in our multidisciplinary pediatric intestinal rehabilitation program. Median (interquartile range [IQR]) duration of follow-up was 8.7 (3.1-14.3) months. Median (IQR) residual bowel length was 102 (85-130) cm. Median (IQR) citrulline level was 14.5 (10.5-31.3) μmol/L. Diagnoses included isolated gastroschisis (n = 3), gastroschisis with intestinal atresia (n = 4), necrotizing enterocolitis (n = 2), and long-segment Hirschsprung disease (n = 1). Six subjects had at least 1 prior bowel-lengthening procedure. Median (IQR) change in percentage enteral energy intake was 19.9% (15.4%-29.8%) during follow-up (P = 0.01). Seven patients improved in enteral tolerance during treatment and 2 were weaned completely from parenteral nutrition. Complications during therapy were prolonged corrected QT interval (n = 2), gastrointestinal bleeding (n = 2), D-lactic acidosis (n = 1), and death due to presumed sepsis (n = 1). Longitudinal analysis (general estimating equation model) showed a strong positive association between cisapride duration and improved enteral tolerance. Mean percentage of enteral intake increased by 2.9% for every month of cisapride treatment (P < 0.0001). CONCLUSIONS Cisapride is a potentially useful therapy in patients with pediatric short-bowel syndrome with gastrointestinal dysmotility. We observed modest improvement in feeding tolerance where prior treatments failed; however, patients treated with cisapride require careful cardiac monitoring because corrected QT prolongation occurred in 20% of our cohort.

Abstract
Glucagon-like peptide-2 (GLP-2) is a potent intestinotrophic growth factor with therapeutic potential for the prevention or treatment of an expanding number of gastrointestinal diseases, including short bowel syndrome (SBS). Teduglutide, being developed by NPS Allelix and licensee Nycomed, is a protease-resistant analog of GLP-2 for the potential treatment of gastrointestinal disease. Teduglutide has prolonged biological activity compared with native GLP-2, and preclinical studies demonstrated significant intestinotrophic activity in models of SBS, experimental colitis and chemotherapy-induced intestinal mucositis. Patients with SBS rely on parenteral nutrition (PN) following bowel resection, and in a phase III clinical trial with teduglutide, > 20% reduction in PN was observed in patients with SBS receiving teduglutide. A phase II clinical trial for teduglutide in Crohn's disease observed remission rates of 55.6% in patients. At the time of publication, phase III clinical trials for SBS were ongoing, as were preclinical studies for chemotherapy-induced mucositis and pediatric indications. Teduglutide represents a novel, efficacious drug capable of increasing intestinal growth and improving intestinal function, and may change clinical management of intestinal disease and damage.
