The link between celiac disease (CeD) and thyroid dysfunction has been investigated. However, it is uncertain if CeD is causally linked to thyroid dysfunction. A 2-sample Mendelian randomization study was conducted to ascertain the causal connection between CeD and thyroid dysfunction. Using data from the FinnGen Consortium, a 2-sample Mendelian randomization study was conducted to look at the connection between thyroid dysfunction and CeD. Another replication of the data from the UK Biobank was subsequently performed to confirm our findings. Furthermore, a sequence of sensitivity analyses was performed. The inverse variance weighting technique demonstrates that genetically determined CeD is substantially linked with hypothyroidism, thyrotoxicosis, Graves' disease, and free thyroxine. However, no significant associations were found between CeD and thyroid-stimulating hormone or thyroiditis. Moreover, we achieve the same results in duplicate datasets, which increases the reliability of our findings. This study suggests that CeD and thyroid dysfunction are linked, and it gives theoretical support and new ways of thinking about how to diagnose and treat both conditions.

Arquivos de Gastroenterologia 2024Low bone mass density (BMD) is an extraintestinal finding in celiac disease (CD). This may result in bone fractures leading to loss in quality of life.
BACKGROUND
Low bone mass density (BMD) is an extraintestinal finding in celiac disease (CD). This may result in bone fractures leading to loss in quality of life.
OBJECTIVE
To assess BMD in male CD patients at diagnosis according to the patient's age.
METHODS
Descriptive retrospective carried out during the period between 2013 and 2023 in a single office that studied dual-energy X-ray absorptiometry (DXA) results in 28 male patients with a recent diagnosis of CD, divided into three groups: group 1 (age up to 18 years); group 2 (from 19 to 49 years of age) and group 3 (over 50 years of age). Were studied demographic and anthropometric parameters, time delay between symptoms onset and CD diagnosis and fracture occurrence.
RESULTS
Celiac patients studied had median age 36.0 years (IQR=16.5-50.7). Among them, 39.3% had osteopenia and 14.3% had osteoporosis. Only 36% of the sample had normal DXA values (group 1 with 37.5%; group 2 with 46% and group 3 with 14.2%). No pathological fracture was observed in this sample. CD diagnosis delay observed had median 1.0 year (IQR=1.0-4.7). When the number of individuals with normal and abnormal DXA results were compared, there was no difference in body mass index, time of diagnosis delay or Marsh classification (P=0.18).
CONCLUSION
Male patients at the time of CD diagnosis showed a high prevalence of low BMD, which was particularly evident in individuals over 50 years of age.

Review
PURPOSE
Understanding the quality of life and the factors that influence it for patients with short bowel syndrome (SBS) and their caregivers is of utmost importance in order to enhance their well-being. Therefore, This study aimed to provide a comprehensive understanding of the impact of SBS on patients and their caregivers, as well as its associated factors, by synthesizing the available evidence.
METHODS
A systematic review of the literature was done using PubMed, Embase databases, CNKI, and ISPOR conference papers. Included articles were manually searched to identify any other relevant studies. Quality was assessed using appropriate Joanna Briggs Institute critical appraisal tools.
RESULTS
This review included 16 studies, comprising 15 observational studies and 1 randomized controlled trial. The findings revealed that the QoL of patients with SBS was lower than that of the general population regarding physical functioning and psychological domain. Meanwhile, caregivers experienced challenges in maintaining their QoL. The QoL of SBS patients was found to be influenced by various factors such as treatment, age, sex, stoma, and small intestine length. Among them, the treatment is the most noteworthy factor that can be effectively improved through external interventions.
CONCLUSION
While numerous studies have provided insights into the compromised QoL experienced by individuals with SBS and their caregivers, there remains a scarcity of large-sample quantitative investigations examining the determinants of QoL. The existing body of literature on caregivers is also notably deficient.

Review
Autoimmune thyroid diseases (AITD) are among the most frequent autoimmune disorders, with a multifactorial etiology in which both genetic and environmental determinants are probably involved. Celiac disease (CeD) also represents a public concern, given its increasing prevalence due to the recent improvement of screening programs, leading to the detection of silent subtypes. The two conditions may be closely associated due to common risk factors, including genetic setting, changes in the composition and diversity of the gut microbiota, and deficiency of nutrients like vitamin D. This comprehensive review discussed the current evidence on the pivotal role of vitamin D in modulating both gut microbiota dysbiosis and immune system dysfunction, shedding light on the possible relevance of an adequate intake of this nutrient in the primary prevention of AITD and CeD. While future technology-based strategies for proper vitamin D supplementation could be attractive in the context of personalized medicine, several issues remain to be defined, including standardized assays for vitamin D determination, timely recommendations on vitamin D intake for immune system functioning, and longitudinal studies and randomized controlled trials to definitely establish a causal relationship between serum vitamin D levels and the onset of AITD and CeD.

Potential celiac disease (PCD) is a clinical condition characterised by the presence of a positive CD-specific serology and a normal intestinal architecture. Asymptomatic PCD patients are generally advised to continue on a gluten-containing diet (GCD), but long-term risks of this approach have never been explored. In the present study, we aimed to investigate nutritional and autoimmune complications possibly developing overtime in a cohort of asymptomatic PCD children on a GCD. We compared children's parameters of growth, nutritional status, and autoimmunity between the time of diagnosis and on the occasion of their last medical check, after a long-term gluten-containing diet. Altogether, we collected data from 171 PCD children with a mean follow-up time of 3 years (range 0.35-15.3 years). During follow-up, although patients did not reduce their amount of daily gluten intake, their anti-tissue transglutaminase (anti-TG2) antibodies spontaneously and significantly decreased. Most parameters analysed had not changed during follow-up (height centile, ferritin, albumin, cholesterol, calcium, alkaline phosphatase, parathormone, and vitamin D) or even improved significantly (weight and BMI centile, haemoglobin, blood iron, HDL, glycaemia, and HbA1C, < 0.05), always remaining within the limit of normality. Equally, autoantibodies for other concomitant autoimmune disorders did not increase overtime. Similar results were obtained excluding from analysis patients who had stopped producing anti-TG2 and those with a follow-up time < 3 years. Our pilot study has provided reassuring results regarding the maintenance of a gluten-containing diet in asymptomatic PCD children, even when long-term follow-up was considered.

Review
There is increasing evidence indicating that changes in both the composition and functionality of the intestinal microbiome are closely associated with the development of several chronic inflammatory diseases, with celiac disease (CeD) being particularly noteworthy. Thanks to the advent of culture-independent methodologies, the ability to identify and quantify the diverse microbial communities residing within the human body has been significantly improved. However, in the context of CeD, a notable challenge lies in characterizing the specific microbiota present on the mucosal surfaces of the intestine, rather than relying solely on fecal samples, which may not fully represent the relevant microbial populations. Currently, our comprehension of the composition and functional importance of mucosa-associated microbiota (MAM) in CeD remains an ongoing field of research because the limited number of available studies have reported few and sometimes contradictory results. MAM plays a crucial role in the development and progression of CeD, potentially acting as both a trigger and modulator of the immune response within the intestinal mucosa, given its proximity to the epithelial cells and direct interaction. According to this background, this review aims to consolidate the existing literature specifically focused on MAM in CeD. By elucidating the complex interplay between the host immune system and the gut microbiota, we aim to pave the way for new interventions based on novel therapeutic targets and diagnostic biomarkers for MAM in CeD.

BACKGROUND
The diagnosis of coeliac disease (CD) in adults is based on clinical, serological and histological criteria. The inappropriate performance of intestinal biopsies, non-specificity of mild histological lesions and initiation of a gluten-free diet (GFD) before biopsy may hamper the diagnosis. In these situations, determining the intraepithelial lymphogram of the duodenum by flow cytometry (IEL-FC) can be helpful.
OBJECTIVES
To describe the clinical scenarios in which the IEL-FC is used and its impact on the diagnosis of CD.
METHODS
All adult patients with suspected CD at three tertiary centres for whom the duodenal histology and IEL-FC were available were identified. Catassi and Fasano's diagnostic criteria and changes to a CD diagnosis after the IEL-FCs were collected.
RESULTS
A total of 348 patients were included. The following indications for an IEL-FC formed part of the initial study for CD (38%): negative conventional work-up (32%), already on a GFD before duodenal biopsies (29%) and refractoriness to a GFD (2%). The IEL-FC facilitated a definitive diagnosis in 93% of patients with an uncertain diagnosis who had had a conventional work-up for CD or who were on a GFD before histology.
CONCLUSIONS
The IEL-FC facilitates the confirmation or rejection of a diagnosis of CD in clinical scenarios in which a conventional work-up may be insufficient.

Review
Multiple endocrine neoplasia type 1 (MEN1) is a rare syndrome caused by inactivating mutations in the MEN1 tumor suppressor gene. The three main clinical manifestations of MEN1 are primary hyperparathyroidism (PHPT), duodenal-pancreatic neuroendocrine tumors (DP-NETs) and anterior pituitary tumors. Endocrine tumors in patients with MEN1 differ from sporadic tumors because of their younger age at onset, common multiple presentations and the different clinical course. MEN1 is characterized by a complex clinical phenotype; thus, patients should be followed by a multidisciplinary team of experts that includes an endocrinologist, a surgeon, a oncologist, a radiotherapist, and not least, a nutritionist. It is important to remember the fundamental role that diet plays as a primary prevention tool, together with a healthy and active lifestyle in preventing osteoporosis/osteopenia and reducing the risk of developing kidney stones due to hypercalciuria, two frequent clinical complications in MEN1 patients. Is very important for MEN1 patients to have an adequate intake of calcium, vitamin D, magnesium and phosphate to maintain good bone health. The intake of foods containing oxalates must also be kept under control because in combination with calcium they concur to form calcium oxalate crystals, increasing the risk of nephrolithiasis. Another aspect to consider is the management of patients with pancreatic neuroendocrine tumors undergoing major surgical resections of the pancreas that can lead to alterations in digestion and absorption mechanisms due to partial or total reduction in pancreatic enzymes such as amylase, lipase, and protease, resulting in malabsorption and malnutrition. Therefore, the nutritionist's aim should be to devise a dietary plan that takes into consideration each single patient, educating them about a healthy and active lifestyle, and accompanying them through various life stages by implementing strategies that can enhance their quality of life.

The D-enantiomer of lactic acid (D-lactate) is normally produced from bacterial fermentation in the gastrointestinal tract in mammals. In humans, increased D-lactate concentrations are related to gastrointestinal disease, including short bowel syndrome and malabsorptive syndrome. Similarly, increased D-lactate concentrations have been described in calves affected by diarrhea, in cats with gastrointestinal diseases, and in dogs with parvoviral enteritis. The purpose of the present study was to measure the serum D-lactate concentrations in dogs with inflammatory bowel disease (IBD). We retrospectively reviewed data from the database of the VTH of Perugia University, and dogs affected by IBD with serum samples stored at -80 °C were considered eligible for inclusion. A total of 18 dogs with IBD and 10 healthy dogs were included in the study. The dogs with IBD were divided into three subcategories based on the severity of the disease. Serum D-lactate concentrations (μM) were determined using a commercially available colorimetric assay kit (D-Lactate Colorimetric Assay Kit; Catalog #K667-100, BioVision Inc., Milpitas, CA, USA). Our results showed no significant difference ( > 0.05) in the serum concentrations of D-lactate between dogs with various degrees of IBD and healthy dogs. However, the wide variability of the D-lactate concentrations in dogs with IBD and evidence of increased serum D-lactate concentrations in dogs with confirmed dysbiosis encourage further studies on this topic to understand potential factors influencing the serum D-lactate concentrations in dogs affected by IBD.

Inflammatory bowel disease (IBD) is a chronic disease characterized by different cell infiltrates in the intestine. The aims of this study were to report the clinical and clinicopathological findings in horses with histological changes compatible with IBD in the duodenum. Further, the clinical progression of IBD and survival were investigated. Patient records were reviewed for horses in which histological evidence of IBD was found in duodenal biopsies collected during endoscopy. The histological changes were classified as mild, moderate or severe and the predominant infiltrating cell type was recorded. Clinical improvement was assessed by the owner via a questionnaire at 6 weeks after biopsy, along with survival after one year. In total, 149 horses were included, and the most common clinical signs were weight loss, reduced performance and pain during abdominal palpation. Most horses showed partial malabsorption during an oral glucose absorption test, and the horses with severe IBD had lower serum protein concentrations. Lymphoplasmacytic enteritis was the most common type of IBD (78.5% of cases), while in six horses neutrophilic infiltration of the duodenum was present. Overall, 71% of the cases had improved clinically after six weeks, mostly following treatment with corticosteroids. The results of a second biopsy were a poor predictor of improvement, and the horses that improved after 6 weeks were more likely to be alive after one year.
