Scand J Gastroenterol 2024; 59:1049-1054. [PMID: 39126366 DOI: 10.1080/00365521.2024.2390016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/05/2024] [Revised: 07/21/2024] [Accepted: 08/04/2024] [Indexed: 08/12/2024]
Abstract
BACKGROUND People with coeliac disease (CD) are at increased risk of osteoporosis and fractures. Currently, baseline dual-energy X-ray absorptiometry (DXA) is recommended for all patients with newly diagnosed CD. We aimed to determine the prevalence of osteoporosis and the clinical utility of the Fracture Risk Assessment Tool (FRAX) in predicting major osteoporotic fractures (MOF) in patients with biopsy-proven CD. METHODS We retrospectively collected data for consecutive adult patients with biopsy-proven CD between 2001 and 2015 who underwent DXA scanning within 1 year of diagnosis and were followed up for a minimum of 7 years. Fracture risk was assessed using FRAX scores, and the incidence of major osteoporotic fractures during the follow-up period was analysed. RESULTS A total of 593 patients (median age 45.0 years, 68.5% female) were included. The prevalence of osteopenia and osteoporosis were 32.3% and 14.5%, respectively. Increasing age (OR 1.06, p < .0001), decreasing BMI (OR 0.90, p = .003), and higher baseline immunoglobulin A-tissue tissue transglutaminase titre (OR 1.04, p = .03) were significantly associated with increased risk of osteoporosis. The sensitivity, specificity, positive and negative predictive values of the FRAX tool to predict MOF were 21.2%, 91.3%, 16.3%, 93.5%, respectively. A higher risk of fractures was associated with ongoing gluten exposure (OR 1.86, p = .02), previous fractures (OR 2.69, p = .005), and older age (OR 1.03, p < .0001). CONCLUSION Osteoporosis is a common finding in patients with CD. The FRAX tool showed high specificity in predicting osteoporotic fractures and could be used to aid with patient selection for DXA scanning in some cases.

Abstract
Although many biomarkers have been proposed, and several are in widespread clinical use, there is no single readout or combination of readouts that correlates tightly with gluten exposure, disease activity, or end-organ damage in treated patients with celiac disease. Challenges to developing and evaluating better biomarkers include significant interindividual variability-related to immune amplification of gluten exposure and how effects of immune activation are manifest. Furthermore, the current "gold standard" for assessment of end-organ damage, small intestinal biopsy, is itself highly imperfect, such that a marker that is a better reflection of the "ground truth" may indeed appear to perform poorly. The goal of this review was to analyze past and present efforts to establish robust noninvasive tools for monitoring treated patients with celiac disease and to highlight emerging tools that may prove to be useful in clinical practice.

Abstract
Celiac disease (CD) is an autoimmune disease caused by an abnormal immune response triggered by ingestion of gluten. Treatment of CD is a lifelong gluten-free diet. Both diagnosed and undiagnosed CD has been found to be associated with reduced bone mineral density, which can lead to an increased risk of fractures. We therefore aimed to investigate the association of CD and the risk of fractures and osteoporosis in Denmark in a nationwide registry-based study. We identified all patients with CD (ICD-10 code K90.0) between 2000 and 2018 and included those with at least two contacts with a CD diagnosis. In total, 9397 CD patients and 93,964 randomly selected age- and sex-matched (1:10) references from the general population were identified. The overall hazard ratio (HR) of developing osteoporosis in CD patients compared with matches was 5.39 (95 % confidence interval (CI): 4.89, 5.95), however when excluding events of osteoporosis occurring within 12 months from the date of diagnosis the overall HR was reduced to 3.87 (95 % CI: 3.44, 4.33). The HR for major osteoporotic fractures was 1.37 (95 % CI: 1.25, 1.51) and for any fractures 1.27 (95 % CI: 1.18, 1.36). For osteoporosis, major osteoporotic fractures, and any fracture prior to diagnosis of CD the odds ratios comparing CD patients with matches were 4.32 (95 % CI: 3.64, 4.68), 1.29 (95 % CI: 1.21, 1.37) and 1.34 (95 % CI: 1.27, 1.41), respectively. Thus, this study showed an increased risk of osteoporosis and bone fractures among individuals with CD, both before and after diagnosis of CD. These results underline that the risk of osteoporosis should be considered in the clinical management of patients with CD and that early diagnosis and treatment could be important.

Evolution of bone densitometry parameters and risk of fracture in coeliac disease: a 10-year perspective. Intern Emerg Med 2023; 18:1405-1414.

Abstract
BACKGROUND Metabolic bone disease is frequently found in patients with coeliac disease (CD). Despite its high prevalence, international guidelines are partially discordant about its management due to the lack of long-term data. METHODS We retrospectively evaluated a large dataset of prospectively collected data of CD patients assessing the variation of DXA parameters and estimated fracture risk according to the FRAX® score in a 10-year follow-up. Incident fractures are reported, and the predictive ability of the FRAX® score is verified. RESULTS We identified 107 patients with low bone density (BMD) at the diagnosis of CD and a 10-year follow-up. After improving at the first follow-up, T-scores slowly reduced over time but with no clinically relevant differences between the first and last examination (lumbar spine: from - 2.07 to - 2.07, p = 1.000; femoral neck: from - 1.37 to - 1.55, p = 0.006). Patients with osteoporosis at the index measurement had more marked fluctuations than those with osteopenia; the latter group also showed minimal modifications of the FRAX® score over time. Six incident major fragility fractures occurred, with a good predictive ability of the FRAX® (AUC 0.826). CONCLUSION Adult CD patients with osteopenia and no risk factors had substantially stable DXA parameters and fracture risk during a 10-year follow-up. A dilated interval between follow-up DXA for these patients could be considered to reduce diagnosis-related time and costs, maintaining a 2-year interval for patients with osteoporosis or risk factors.

Abstract
Coeliac disease is a common autoimmune disorder induced by ingesting gluten, the protein component of wheat, barley, and rye. It is estimated that one-in-hundred people worldwide have coeliac disease, of whom the majority remain undiagnosed. Coeliac disease is characterized by a wide range of gastrointestinal and extraintestinal symptoms but can also present asymptomatically. Diagnosing coeliac disease depends on the concordance of clinical, serological and histopathological data. However, the diagnosis can be challenging and frequently overlooked. Undiagnosed coeliac disease is associated with an increased risk of complications and detrimental effects on quality of life. Early diagnosis and treatment of coeliac disease are necessary to reduce the risk of long-term complications.

Abstract
Celiac disease (CD) is an autoimmune disorder caused by gluten ingestion in genetically predisposed individuals. In addition to the typical gastrointestinal symptoms (e.g., diarrhea, bloating, and chronic abdominal pain), CD may also present with a broad spectrum of manifestations, including low bone mineral density (BMD) and osteoporosis. The etiopathology of bone lesions in CD is multifactorial and other conditions, rather than mineral and vitamin D malabsorption, may affect skeletal health, especially those related to the endocrine system. Here, we describe CD-induced osteoporosis in an attempt to enlighten new and less-known aspects, such as the influence of the intestinal microbiome and sex-related differences on bone health. This review describes the role of CD in the development of skeletal alterations to provide physicians with an updated overview on this debated topic and to improve the management of osteoporosis in CD.

Abstract
INTRODUCTION Coeliac disease and dermatitis herpetiformis are immune-mediated diseases triggered by the consumption of gluten in genetically predisposed individuals. These guidelines were developed to provide general practitioners, paediatricians, gastroenterologists, and other clinicians with an overview on the diagnosis, management and follow-up of coeliac patients and those with dermatitis herpetiformis. METHODS Guidelines were developed by the Italian Societies of Gastroenterology. Following a systematic literature review, the Grading of Recommendations Assessment, Development and Evaluation methodology was used to assess the certainty of the evidence. Statements and recommendations were developed by working groups consisting of gastroenterologists and a paediatrician with expertise in this field. RESULTS These guidelines provide a practical guidance for the diagnosis, management and follow-up of coeliac patients and dermatitis herpetiformis in children and adults, both in primary care and in specialist settings. We developed four sections on diagnosis, gluten-free diet, follow-up and risk of complications in adults, one section focused on diagnosis and follow-up in children and one on the diagnosis and management of dermatitis herpetiformis. CONCLUSIONS These guidelines may support clinicians to improve the diagnosis and management of patients with coeliac disease.

Abstract
BACKGROUND The best-known symptoms of coeliac disease are related to the gastrointestinal tract, but the disease may also present with various systemic manifestations outside the intestine. Some of these consequences may remain permanent in undiagnosed individuals or if the diagnostic delay is prolonged. However, for many of the systemic manifestations, the scientific evidence remains scant and contradictory. AIMS AND METHODS We conducted a narrative review of the most thoroughly studied and clinically relevant systemic consequences of coeliac disease, especially those that could be prevented or alleviated by early diagnosis. The review is intended particularly for physicians encountering these patients in daily clinical practice. RESULTS The possible systemic consequences of coeliac disease extend to multiple organ systems, the best studied of which are related to skeletal, reproductive, cardiovascular and neurological systems. Furthermore, the disease is associated with an elevated risk of psychiatric comorbidities, non-Hodgkin lymphomas and intestinal adenocarcinoma. CONCLUSIONS The various systemic consequences of coeliac disease play a significant role in the overall health of patients. Early diagnosis and treatment with a gluten-free diet appear to be beneficial for most, but not all of these conditions. The possible negative metabolic and psychosocial effects of the diet should be acknowledged during follow-up.

Abstract
Numerous disorders can alter the physiological mechanisms that guarantee proper digestion and absorption of nutrients (macro- and micronutrients), leading to a wide variety of symptoms and nutritional consequences. Malabsorption can be caused by many diseases of the small intestine, as well as by diseases of the pancreas, liver, biliary tract, and stomach. This article provides an overview of pathophysiologic mechanisms that lead to symptoms or complications of maldigestion (defined as the defective intraluminal hydrolysis of nutrients) or malabsorption (defined as defective mucosal absorption), as well as its clinical consequences, including both gastrointestinal symptoms and extraintestinal manifestations and/or laboratory abnormalities. The normal uptake of nutrients, vitamins, and minerals by the gastrointestinal tract (GI) requires several steps, each of which can be compromised in disease. This article will first describe the mechanisms that lead to poor assimilation of nutrients, and secondly discuss the symptoms and nutritional consequences of each specific disorder. The clinician must be aware that many malabsorptive disorders are manifested by subtle disorders, even without gastrointestinal symptoms (for example, anemia, osteoporosis, or infertility in celiac disease), so the index of suspicion must be high to recognize the underlying diseases in time.
