Budesonide Induces Favourable Histologic and Symptomatic Recovery in Patients with Non-responsive and Refractory Coeliac Disease When Given in an Open Capsule Format. Dig Dis Sci 2024; 69:2548-2557. [PMID: 38683433 PMCID: PMC11258102 DOI: 10.1007/s10620-024-08436-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/09/2023] [Accepted: 04/10/2024] [Indexed: 05/01/2024]
Abstract
INTRODUCTION Non-responsive coeliac disease (NRCD), where symptoms and enteropathy persist despite a prolonged gluten-free diet (GFD), is common. Refractory coeliac disease (RCD), characterised by malabsorption and extensive enteropathy, is rare but serious. In both, treatment options are limited. Topical budesonide may help and an open capsule format promoting proximal small intestinal delivery may be advantageous. AIM To describe the effect of budesonide and its presentation on mucosal healing, symptoms, and tolerability in NRCD and RCD. METHODS A retrospective cohort study of NRCD and RCD patients who received budesonide for enteropathy despite a strict GFD for over 12 months. Primary outcome was improvement in histology. Symptoms and adverse treatment effects were recorded. RESULTS 50 patients with NRCD (n = 14; 86% F), RCD type 1 (n = 30; 60% F), and RCD type 2 (n = 6 based on aberrant duodenal T cells; 33% F) were identified. Common RCD symptoms were diarrhoea (68%), fatigue (40%), and weight loss (34%). 16 received closed capsule budesonide (CCB) 9 mg OD and 35 open capsule budesonide (OCB) 3 mg 3 times a day. Complete and partial mucosal healing was significantly higher after OCB compared to CCB (p < 0.001, Mann-Whitney U test). Symptom improvement was also significantly higher after OCB compared to CCB (p = 0.002, Mann-Whitney U test). Side effects were mild and self-limiting and were reported in 25% of both cohorts. CONCLUSION OCB was well tolerated and associated with improvements in enteropathy (83%) and symptoms (90%) in NRCD and RCD. Our findings support OCB as the preferred 1st-line therapy for NRCD and RCD type 1.

Abstract
Celiac disease (CD) is a chronic enteropathy caused by the ingestion of gluten in a genetically susceptible individual. Currently, a gluten-free diet (GFD) is the only recommended treatment. However, unintentional gluten ingestion or a persistent villous atrophy with malabsorption (regardless of a strict GFD) as in the case of Refractory Celiac Disease (RCD) represents a major issue. In this review, we have analysed and discussed data from both randomized controlled trials and observational studies concerning adjunctive therapies as well as novel therapies for the treatment of CD and RCD. The literature search was carried out through Medline and Scopus. In total, 2268 articles have been identified and 49 were included in this review (36 studies resulting from the search strategy and 13 from other sources). Today, GFD remains the only effective treatment, although steroids, mesalamine, and more recently biological therapies have found space in the complex management of RCD. Currently, studies evaluating the effectiveness of novel therapies are still limited and preliminary results have been controversial.

Abstract
OBJECTIVES Non-responsive celiac disease (NRCD) is defined as patients having persistent symptoms and enteropathy (Marsh 3 histology) suggestive of active celiac disease (CeD), after following a gluten-free diet (GFD) for at least 12 months. NRCD is suggested to affect 15% of children with CeD but data are limited and there is no research to date describing treatment of children with this condition. The aim of this study was to describe our center's approach to identifying and treating NRCD with budesonide and the Gluten Containing Elimination Diet (GCED). METHODS We performed a retrospective, single center analysis over a 5-year period of patients with CD less than 18 years of age (inclusive) who underwent treatment for persistent symptoms and enteropathy despite following a GFD. RESULTS We identified 22 patients with NRCD. Thirteen were treated with the GCED for 3 months with 46% achieving both histological and symptomatic resolution. Nine patients were treated with budesonide (6-9 mg), with 89% achieving both symptomatic and histologic resolution after a median 3-month treatment course. Further, 67% of patients who responded to the GCED and 100% of patients who responded to budesonide remained in remission for at least 6 months following treatment transition back to exclusive GFD. CONCLUSIONS The GCED and budesonide can provide benefit for NRCD. Most patients with NRCD can return to a GFD after 3 months of treatment.

Abstract
BACKGROUND The association between celiac disease and inflammatory bowel disease (IBD) has been studied; however, the impact of IBD therapy on celiac disease is not known. Using a large database, we sought to describe the association of celiac disease and IBD and the impact of IBD treatment. METHODS We queried a large multicenter database (Explorys Inc.), an electronic health record data aggregate from 26 American health care systems. We identified a cohort of patients with celiac disease and IBD between 1999 and 2020 and conducted a statistical analysis using a multivariate model. RESULTS Of the 72,965,940 individuals in the database, 133,400 had celiac disease (0.18%), 191,570 (0.26%) had ulcerative colitis (UC), and 230,670 (0.32%) had Crohn disease (CD). Patients with IBD were more likely to have a diagnosis of celiac disease (odds ratio [OR], 13.680), with a greater association with CD. Treated patients with UC and with CD, respectively, had a lower risk association with celiac disease compared to those not undergoing IBD treatment, specifically corticosteroids (OR, 0.407 and 0.585), 5-aminosalicylates (OR, 0.124 and 0.127), immunomodulators (OR, 0.385 and 0.425), and anti-tumor necrosis factor drugs (OR, 0.215 and 0.242). There was no lower risk association in the vedolizumab group, but there was a higher risk association among the ustekinumab group. CONCLUSIONS In this large dataset, we showed a bidirectional association between celiac disease and IBD that was stronger with CD. Patients with IBD treated using corticosteroids, 5-aminosalicylates, immunomodulators, or anti-tumor necrosis factor drugs had a lower association with celiac disease. Additional studies are required to determine the underlying mechanisms for IBD therapy-related modification of celiac disease incidence.

Abstract
BACKGROUND Previous studies investigating the prevalence of celiac disease (CD) in individuals with autoimmune hepatitis (AIH) have shown highly variable results. We therefore aimed to examine the prevalence of CD in individuals with AIH. METHODS Two professional librarians searched PubMed, EMBASE, Cochrane and Web of Science Core Collection up until 7 February 2020. The search terms included 'celiac disease', 'celiac', 'transglutaminases', 'gluten', 'gliadin', 'EMA', 'TTG' and 'villous' combined with 'autoimmune', 'hepatitis', 'ANA', 'SMA' and 'LKM'. This search yielded 2419 unique publications. A systematic review based on the PRISMA guidelines resulted in 31 articles eligible for full text review. Fifteen articles were deemed relevant, with 8 being included in our main analysis. A fixed-effect inverse variance-weighted model was used, and heterogeneity was calculated. RESULTS Our main analysis included 567 individuals with AIH from eight studies, where biopsy-verified CD (equivalent to Marsh III) was seen in 23 individuals (4.1%). The pooled prevalence of CD in AIH was 3.5% (95% CI = 1.6%-5.3%) (heterogeneity: P = .874; I2 = 0.0%), which is clearly higher than the 1% CD seen in most general populations. When also including studies where CD had been diagnosed through positive serology without biopsy (15 studies: n = 1817 individuals with AIH), the pooled prevalence of CD was 2.9% (95% CI = 2.1%-3.8%) (heterogeneity: P < .001; I2 = 66.8%). CONCLUSION Our results demonstrate a higher prevalence of CD in individuals with AIH compared to the general population. CD screening may be considered in patients with AIH.

Abstract
BACKGROUND Non-responsive celiac disease (NRCD) has many aetiologies, including gluten exposure. Budesonide may be used for refractory celiac disease (RCD) and celiac crisis. AIMS We reviewed the effectiveness of budesonide to induce clinical and histologic response in NRCD with villous atrophy (VA). METHODS Case series of adult cases with NRCD and VA prescribed budesonide at two celiac centers. Clinical variables and mucosal recovery (i.e., normal villous architecture within 1 year of treatment) were evaluated. RESULTS Forty-two cases [77% female, median age 45.0 (IQR 28.3-60.0) years] were included. Most common symptoms were diarrhea (64%) and abdominal pain (62%). Budesonide was initiated at 9 mg (83%) for a median duration of 16.0 weeks (IQR 6.8-25.0 weeks). In total, 57% exhibited a clinical response, positively associated with diarrhea (adjusted OR 6.08 95% CI 1.04-35.47) and negatively with fatigue (adjusted OR 0.18 95% CI 0.03-0.98). Clinical response was higher among those with dietitian counseling prior to budesonide (n = 29, 70 vs. 23%, p < 0.01). Mucosal recovery was observed in 11/24 with follow-up duodenal biopsies. There was no association between clinical response and mucosal recovery, and 79% of clinical responders had a symptomatic relapse. RCD (48%) and chronic gluten exposure (24%) were the main suspected aetiologies of NRCD. Most individuals without a clinical response subsequently received an IBS-related diagnosis. CONCLUSIONS Budesonide may be effective to induce clinical response in NRCD presenting with diarrhea and VA, but clinical recurrence and lack of mucosal recovery are frequent after tapering. Other diagnoses, including coexisting IBS, may be considered in non-responders to budesonide therapy.

Abstract
BACKGROUND Celiac disease is an intestinal chronic disorder with multifactorial etiology resulting in small intestinal mucosal injuries and malabsorption. In genetically predisposed individuals with HLA DQ2/DQ8 molecules, the gluten domains rich in glutamine and proline present gluten domains to gluten reactive CD4+ T cells causing injury to the intestine. In the present experimental design, the indigenous bacteria from wheat samples were studied for their gluten hydrolyzing functionality. RESULTS Proteolytic activity of Bacillus spp. was confirmed spectrophotometrically and studied extensively on gliadin-derived synthetic enzymatic substrates, natural gliadin mixture, and synthetic highly immunogenic 33-mer peptide. The degradation of 33-mer peptide and the cleavage specificities of the selected isolates were analyzed by tandem mass spectrometry. The gluten content of the sourdough fermented by the chosen bacterial isolates was determined by R5 antibody based competitive ELISA. All the tested isolates efficiently hydrolyzed Z-YPQ-pNA, Z-QQP-pNA, Z-PPF-pNA, and Z-PFP-pNA and also cleaved 33-mer immunogenic peptide extensively. The gluten content of wheat sourdough was found to be below 110 mg/kg. CONCLUSION It has been inferred that four Bacillus spp especially GS 188 could be useful in developing gluten-reduced wheat food product for celiac disease prone individuals.

Abstract
Gluten is known to be the main triggering factor for celiac disease (CeD), an immune-mediated disorder. CeD is therefore managed using a strict and lifelong gluten-free diet (GFD), the only effective treatment available currently. However, the GFD is restrictive. Hence, efforts are being made to explore alternative therapies. Based on their mechanisms of action on various molecular targets involved in the pathogenesis of CeD, these therapies may be classified into one of the following five broad approaches. The first approach focuses on decreasing the immunogenic content of gluten, using strategies like genetically modified wheat, intra-intestinal gluten digestion using glutenases, microwave thermal treatment of hydrated wheat kernels, and gluten pretreatment with either bacterial/ fungal derived endopeptidases or microbial transglutaminase. The second approach involves sequestering gluten in the gut lumen before it is digested into immunogenic peptides and absorbed, using binder drugs like polymer p(HEMA-co-SS), single chain fragment variable (scFv), and anti- gluten antibody AGY. The third approach aims to prevent uptake of digested gluten through intestinal epithelial tight junctions, using a zonulin antagonist. The fourth approach involves tissue transglutaminase (tTG) inhibitors to prevent the enhancement of immunogenicity of digested gluten by the intestinal tTG enzyme. The fifth approach seeks to prevent downstream immune activation after uptake of gluten immunogenic peptides through the intestinal mucosal epithelial layer. Examples include HLA-DQ2 blockers that prevent presentation of gluten derived- antigens by dendritic cells to T cells, immune- tolerizing therapies like the vaccine Nexvax2 and TIMP-Glia, cathepsin inhibitors, immunosuppressants like corticosteroids, azathioprine etc., and anti-cytokine agents targeting TNF-α and interleukin-15. Apart from these approaches, research is being done to evaluate the effectiveness of probiotics/prebiotics, helminth therapy using Necator americanus, low FODMAP diet, and pancreatic enzyme supplementation in CeD symptom control; however, the mechanisms by which they play a beneficial role in CeD are yet to be clearly established. Overall, although many therapies being explored are still in the pre-clinical phase, some like the zonulin antagonist, immune tolerizing therapies and glutenases have reached phase II/III clinical trials. While these potential options appear exciting, currently they may at best be used to supplement rather than supplant the GFD.

Abstract
Celiac disease (CD)—also known as gluten-sensitive enteropathy—is a chronic, genetically predisposing and autoimmune entity with a wide range of clinical manifestations triggered by gluten ingestion, which affects 1% of the general population. Currently, up to 60% of the diagnosis of CD is in adults due to the atypical course of the disease. The severe acute onset of CD—also called celiac crisis—is very uncommon and is still not well documented in adults. We report the case of a 58-year-old man who presented a 45-day history of subtle-onset diarrhea followed by malabsorption syndrome with progressive weight loss, anasarca, and electrolyte disturbances. The diagnostic work-up included an upper digestive endoscopy, which showed scalloping of the duodenal mucosa with pathological features confirmed on biopsies. Specific antibodies were positive, and a satisfactory clinical response was obtained once a gluten-free diet was started. Celiac crisis is a rare initial presentation of CD characterized by severe diarrhea, dehydration, weight loss, hypoproteinemia, and metabolic and electrolyte disturbances. Although rare, it should be considered in patients with apparently unexplained chronic diarrhea.

Abstract
INTRODUCTION Despite decades of research and a detailed knowledge of the immunopathological basis of coeliac disease (CD), adherence to a lifelong gluten-free diet (GFD) remains the single proven and available treatment. The increasing prevalence of CD combined with variable adherence to the GFD in a significant proportion of patients demands new therapeutic strategies. AREAS COVERED Trial registries, clinicaltrials.gov, pharmaceutical company website searches as well as published data from PubMed and conference proceedings were used to extract the most recent outcomes for CD therapeutics. This article aims to review the available therapies from a pathophysiological approach, and propose future directions in this interesting yet largely unfulfilled area of research. EXPERT OPINION Increasingly, the GFD is being challenged by its availability, palatability, practicality and now even efficacy in some populations. Whilst the causative antigens have been well described, it is clear that treatment based on the removal of these immunostimulatory peptides from the diet is far more complex than early experience in CD treatment implied. Despite burgeoning interest and research in experimental therapies for CD over the past twenty years, the only therapy showing promise as a true alternative to a GFD is that of the induction of tolerance via a vaccine.

Abbas A, Shahab T, Sherwani RK, Alam S. Addition of a Short Course of Prednisolone to a Gluten-Free Diet vs. Gluten-Free Diet Alone in Recovery of Celiac Disease: A Pilot Randomized Controlled Trial. Cureus 2018; 10:e2118. [PMID: 29600122 PMCID: PMC5873829 DOI: 10.7759/cureus.2118] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2017] [Accepted: 01/28/2018] [Indexed: 11/16/2022] Open
Abstract
Background A gluten-free diet (GFD) is the standard of care in the management of patients with celiac disease, but clinical and histological recovery are often delayed. In newly diagnosed patients, strict compliance to GFD is difficult to achieve; this is especially true in developing countries where gluten-free food is often difficult to obtain. Steroids, when used alone, can be effective in inducing recovery in patients with celiac disease. We performed a randomized controlled trial to study the effect of a short course of prednisolone combined with a GFD on the recovery of celiac disease. Materials and methods This study was a single-center, randomised, open-label trial. This investigation was done in a pediatric gastroenterology unit of a tertiary teaching hospital in north India.Twenty-eight newly diagnosed celiac disease patients were enrolled in the study. Prednisolone was given at 1 mg/kg for four weeks; duodenal biopsies and IgA anti-tissue transglutaminase (tTg) levels were assessed at eight weeks, six months, and 12 months from the start of the study. Outcome measures The primary outcome measures used to indicate clinical, histological, and immunological recovery of celiac disease were clinical improvement at eight weeks and the proportion of patients with improved histology by at least one grade and who were tissue transglutaminase (tTg) seronegative at eight weeks. The secondary measures were the proportion of patients showing normalization of histological features and the proportions of patients becoming seronegative at six months and one year of GFD. Results Patients were randomized into the GFD only (n = 14) or GFD with prednisolone (GFD+P) (n = 14) groups. No significant differences were detected in clinical recovery at eight weeks; none of the patients became seronegative at eight weeks, six months, or 12 months. The proportion of patients with improvement in histology by at least one grade was higher in the GFD+P group at eight weeks, and there was no difference in overall histological improvement at 12 months after starting treatment. Conclusion The addition of a short course of prednisolone to a GFD does not affect clinical and serological recovery but might result in rapid histological recovery compared to a GFD alone in patients newly diagnosed with celiac disease.

Abstract
For the majority of patients diagnosed with celiac disease, once a gluten-free diet is initiated, symptoms improve within weeks and may completely resolve in months. However, up to 30% of patients may show signs, symptoms or persistent small intestinal damage after one year on a gluten-free diet. These patients require evaluation for other common GI etiologies and assessment of their celiac disease status in order to make a diagnosis and suggest treatment. Here, we propose an approach to evaluating patients with celiac disease with persistent symptoms, persistently elevated serology, and or persistent villous atrophy despite a gluten-free diet. We detail how to diagnose and distinguish between non-responsive and refractory celiac disease. Finally, we introduce the indications for use of the gluten contamination elimination diet and provide information for practitioners to implement the diet when necessary in their practice.

Abstract
Various experimental model designs have been used to analyze the inflammatory pathways in human gastrointestinal illnesses. Traditionally, analytical techniques and animal models are popular experimental tools to study the inflammation process of intestinal diseases. However, the comparison of results between animal and human models is difficult for the inconsistency of outcomes. Although there are different animal models for studying the intestinal diseases, none of them fully represents the physiological and environmental conditions typical of the human species. Also, there is currently a concerted effort to decrease the experimental use of animals. On the converse, experimental protocols using the culture of gut mucosa had become popular with the advent of endoscopy which allows explanting multiple fragments from the intestine. The peculiar characteristic of this model is the ability to preserve in vitro the features that we found in vivo, thus also the response to various stimuli that differs from person to person. The aim of the present paper is to provide a review of some of the possible uses of the organ intestinal mucosa culture.

Abstract
Coeliac disease (CD) is one of the most common diseases worldwide, resulting from a combination of environmental (gluten) and genetic (human leucocyte antigen (HLA) and non-HLA genes) factors. Depending on the geographical location, the prevalence of CD has been estimated to approximate 0.5-1%. The only treatment currently available for CD is a gluten-free diet (GFD) excluding gluten-containing cereals such as wheat, rye, and barley, and other foodstuffs with natural or added gluten. However, adherence rates and patient acceptance are often poor. Moreover, even in fully adherent patients, the diet may fail to induce clinical or histological improvement. Hence, it is unsurprising that studies show CD patients to be highly interested in non-dietary alternatives. The following review focuses on current pathophysiological concepts of CD, spotlighting those pathways which may serve as new possible, non-dietary therapeutic targets in the treatment of CD.

Abstract
Celiac disease is a common, lifelong autoimmune disorder for which dietary control is the only accepted form of therapy. A strict gluten-free diet is burdensome to patients and can be limited in efficacy, indicating there is an unmet need for novel therapeutic approaches to supplement or supplant dietary therapy. Many molecular events required for disease pathogenesis have been recently characterized and inspire most current and emerging drug-discovery efforts. Genome-wide association studies (GWAS) confirm the importance of human leukocyte antigen genes in our pathogenic model and identify a number of new risk loci in this complex disease. Here, we review the status of both emerging and potential therapeutic strategies in the context of disease pathophysiology. We conclude with a discussion of how genes identified during GWAS and follow-up studies that enhance susceptibility may offer insight into developing novel therapies.

Abstract
At present, strict and lifelong gluten-free diet is the only effective treatment for celiac disease. Even small amounts of gluten (50 mg/day) can be immunogenic; therefore all food and food items and drugs that contain gluten and its derivatives must be eliminated completely from the diet. While prescribing gluten-free diet is easy; the key to the success is the dietary counseling by a nutrition specialist and maintenance of adherence to GFD by the patient. In recent times, a number of targets to halt the process of immunological injury have been explored to find out alternative treatment for celiac disease. These targets include exploration of ancient wheat if they are less immunogenic, intra-luminal digestion of gluten using prolylendopeptidases, pretreatment of whole gluten with bacterial-derived peptidase before ingestion; prevention of passage of immunogenic peptides through the tight junctions such as zonulin antagonists, Blocking of HLA-DQ2 to prevent binding of immunogenic peptides, inhibition of transglutaminase 2, immune-modulation, and induction of tolerance to gluten using gluten tolerizing vaccines, use of gluten-sequestering polymers, use of anti-inflammatory drugs (glucocorticoids, budesonides) and anti-cytokines such as anti TNF-α, and anti-interleukin-15. While many of these targets are still in the pre-clinical phase, some of them including zonulin antagonist and endopeptidases have already reached phase II and phase III clinical trials. Furthermore, while these targets appear very exciting; they at best are likely to be used as adjunctive therapy rather than a complete replacement for gluten-free diet.

Effect of addition of short course of prednisolone to gluten-free diet on mucosal epithelial cell regeneration and apoptosis in celiac disease: a pilot randomized controlled trial. Dig Dis Sci 2012; 57:3116-25.

Abstract
BACKGROUND Identification of adjuvant treatment is necessary for rapid and effective treatment in patients with celiac disease. In a pilot randomized controlled trial, the effect of prednisolone on enterocyte apoptosis and regeneration in celiac disease was investigated. PATIENTS AND METHODS Thirty-three treatment-naïve patients with celiac disease were randomized to either gluten-free diet (GFD, n = 17) or GFD + prednisolone (1 mg/kg for 4 weeks, n = 16). Duodenal biopsies were taken at baseline and at 4 and 8 weeks posttreatment. Six patients with functional dyspepsia were recruited as controls. All these biopsies were stained for markers of intrinsic apoptotic pathway (AIF, H2AX, p53), common apoptotic pathway (CC3, M30), apoptotic inhibitors (XIAP, Bcl2), and epithelial proliferation (Ki-67). Apoptotic (AI) and proliferation indices (PI) were compared. RESULTS At baseline duodenal biopsies, the end apoptotic products H2AX and M30 were significantly increased. In comparison with those treated with GFD alone, after 4 weeks of GFD + prednisolone treatment, some markers of both intrinsic and common apoptotic pathways showed rapid decline. After prednisolone withdrawal, there was overexpression of H2AX, CC3, and p53 in the latter group. In comparison with those treated with only GFD, patients treated with prednisolone showed suppression of mucosal PI, which started rising again after withdrawal of prednisolone. CONCLUSIONS Apoptosis takes place in mucosal epithelium in celiac disease. Addition of short course of prednisolone suppresses apoptosis rapidly. However, it also suppresses epithelial regeneration; hence, if used, it should be withdrawn after an initial short course.

Abstract
INTRODUCTION Celiac disease is a common autoimmune condition induced by dietary gluten in genetically susceptible individuals. So far, the only available treatment for the disorder is a lifelong strict gluten-free diet, because of which small intestinal histological changes recover and symptoms disappear. However, gluten-free dieting is restrictive, and nutritionally less than optimal, and gluten is difficult to avoid. AREAS COVERED With improving insight into the pathogenesis of celiac disease, several possible drug targets have been suggested. The new strategies include degradation of gluten intraluminally, reduction of mucosal permeability, inhibition of the transglutaminase 2 enzyme, blocking antigen presentation by HLA-DQ2 or HLA-DQ8, modulation of the immune responses of many cytokines, and vaccination. EXPERT OPINION Non-dietary treatment options are warranted either as adjunctive therapy together with dieting or to replace the gluten-free diet. The key question is whether the envisaged novel drug is able to prevent gluten-induced small intestinal mucosal injury as efficiently as a strict gluten-free diet, alleviating symptoms and signs of the disease. Furthermore, the gluten dose that can be detoxified, if at all, must be established. The new drug should also be as safe as dietary treatment. Several novel treatment options are under development.

Abstract
BACKGROUND Coeliac disease is managed by life-long gluten withdrawal from the diet. However, strict adherence to a gluten-free diet is difficult and is not always effective. Novel therapeutic approaches are needed to supplement or even replace the dietary treatment. AIM To review recent advances in new therapeutic options for coeliac disease. METHODS A literature search was performed on MEDLINE, EMBASE, Web of Science, Scopus, DDW.org and ClinicalTrials.gov for English articles and abstracts. The search terms used included, but not limited to, 'Celiac disease', 'new', 'novel', 'Advances', 'alternatives' and 'Drug therapy'. The cited articles were selected based on the relevancy to the review objective. RESULTS Several new therapeutic approaches for coeliac disease are currently under development by targeting its underlying pathogenesis. Alternative therapies range from reproduction of harmless wheat strains to immunomodulatory approaches. Some of these therapies such as enzymatic cleavage of gluten and permeability inhibitors have shown promise in clinical studies. CONCLUSIONS Gluten-free diet is still the only practical treatment for patients with coeliac disease. Novel strategies provide promise of alternative adjunctive approaches to diet restriction alone for patients with this disorder.

Abstract
Coeliac disease is a widespread, lifelong disorder for which dietary control represents the only accepted form of therapy. There is an unmet need for nondietary therapies to treat this condition. Most ongoing and emerging drug-discovery programmes are based on the understanding that coeliac disease is caused by an inappropriate T-cell-mediated immune response to dietary gluten proteins. Recent genome-wide association studies lend further support to this pathogenic model. The central role of human leucocyte antigen genes has been validated, and a number of new risk loci have been identified, most of which are related to the biology of T cells and antigen-presenting cells. Here, we review the status of potential nondietary therapies under consideration for coeliac disease. We conclude that future development of novel therapies will be aided considerably by the identification of new, preferably noninvasive, surrogate markers for coeliac disease activity.

Abstract
BACKGROUND & AIMS Collagenous sprue (CS) is characterized by the presence of a distinctive band of subepithelial collagen deposition in the small bowel. We evaluated the clinical characteristics, treatments, and outcomes of patients with CS. METHODS Thirty patients with CS were identified at the 3 Mayo Clinic sites between 1993 and 2009. Clinical data from medical records were reviewed. RESULTS The study cohort was 70% female (age range, 53-91 years). Most patients had severe diarrhea and weight loss. Hospitalization to treat dehydration was necessary in 16 (53%) patients. Associated immune-mediated diseases were noted in 70% of the patients; celiac disease was the most frequent. Other associated diseases were microscopic colitis, hypothyroidism, and autoimmune enteropathy. The median thickness of the layer of subepithelial collagen deposition in the small bowel was 29 mum (20-56.5 mum). Subepithelial collagen deposition in the colon or stomach was noted in 8 patients. A clinical response was observed in 24 (80%) patients after treatment with a combination of a gluten-free diet and immunosuppressive drugs. Histologic improvement was confirmed in 9 patients, with complete remission in 5. Two patients died (1 of complications of CS and 1 of another illness). CONCLUSIONS Most patients with CS are treated effectively with a combination of gluten-free diet and steroids. CS is often associated with collagen deposition or chronic inflammation in other segments of the gastrointestinal tract as well as other immune-mediated disorders.
