RÉSUMÉ
OBJECTIVE: Aim: To estimate the differences between patients with celiac disease based on symptoms, diagnosis, treatment, and follow-up. PATIENTS AND METHODS: Materials and Methods: A retrospective cross-sectional study carried out between July 1, 2022 and April 2023, enrolling 200 patients from different provinces of central and south Iraq with Celia disease, whose diagnosis depended on a specialized physician according to WHO guidelines with long-term follow-up. Participants were following up for three to six months in private clinics. Survey was written in English, and the questionnaire form contains 13 fields divided into three sections. Diagnosis of Celia before and after treatment parameters: Tissue Transglutaminase Antibody, IgG, Serum (tTg-Ig G), and tTg-IgA levels the fourth part included a glutin-free diet and symptomatic treatment. RESULTS: Results: Females and ages below 20 were most affected. 176(88%) patients had detectable tTG levels; after 3 months, 72(36.0%) patients had an increase in their body weight but less than 5 kg, while 14(7.0%) of the patients showed an increase of more than 5 kg. But after 6 months, 73(36.5%) patients had an increase in their body weight less than 5 kg, while 45(22.5%) of patients showed an increase of more than 5 kg. CONCLUSION: Conclusions: Celiac patient profile in central Iraq is not different from that in other parts of the world, with typical patient being female and under 30 years of age. The study highlighted to a certain degree that a gluten-free diet can have a modest and promising positive impact on BMI in some patients.

A strict lifelong gluten-free diet (GFD) is the current treatment for the management of celiac disease (CD). Several studies have demonstrated that without proper dietary assessment, this diet leads to nutritional deficiencies and/or imbalances. The present study aimed to improve the dietary habits of newly diagnosed children with CD through ongoing and face-to-face dietary counseling. Forty-three participants were followed during the first year after CD diagnosis. Dietary data were collected at diagnosis (Vt0), after 3 months on a GFD (Vt3), and after 1 year following a GFD (Vt12). Participants completed a 3-day 24-h food recall, a food frequency questionnaire, and the KIDMED index. After each data collection, participants received dietary assessment and nutritional education. Participants consumed more plant-origin foods after the intervention, with most of them reaching the daily recommendations. Fresh food intake increased and that of ultra-processed foods decreased. Compliance with the Mediterranean diet also improved. Personalized dietary assessment and ongoing follow-up improved the dietary patterns of children recently diagnosed with CD, highlighting the importance of dietitian involvement in the management of CD.

This study aims were (i) to describe Italian celiac patients who agreed to participate in the latest web survey and their attitudes toward the GF diet (compliance, perceived limitations, and worries) and (ii) to compare the answers given by the 2011 and 2022 responders. The self-administered questionnaire was distributed through the Italian Coeliac Association channels (link on social media, websites, and newsletters) to all of the celiac patients willing to participate in 2011 and 2022 (2427 and 3529 responders who answered the same questions, respectively). Descriptive analyses and the Pearson's chi-squared test were performed. The responders were 1 to 84 years old and mainly female. The prevalence of adherent patients in 2022 was 91%, with the highest value (94%) in children (≤10 years old) and adolescents (15-17 years old). Overall, young adults were the most worried group. About a decade after the first survey, we observed a decreasing prevalence of transgression events (-5%) and (at least) occasional temptation (-17%), a decreasing prevalence of health-related and general worries, but an increasing prevalence of social life withdrawal. In conclusion, it is important to periodically monitor celiac patients' compliance and attitudes towards the gluten-free diet. As also highlighted in international guidelines, a reorganization of the diagnosis/follow-up visits, including an expert dietary consultation, is needed.

Diet is the only treatment for celiac disease (CeD), and good adherence to a gluten-free diet (GFD) is the only way to ensure complete remission and to prevent complications. Limited education about the disease and a GFD is an attributing factor to inadequate adherence. Thus, our aim was to assess the current knowledge about a GFD and the clinical monitoring of adherence to the diet among CeD people and HCPs. Specific questionnaires were designed and distributed to assess the knowledge of CeD people (Q1 questionnaire) (n = 2437) and to analyze the follow-up of the disease from the perspective of patients (Q2 questionnaire) (n = 1294) and HCPs (Q3 questionnaire) (n = 346). Two-thirds of HCPs specialized in pediatric care, while one-third did so in adult care. In CeD people, general questions regarding food classification and cross-contamination are well understood. When patients have doubts, 51.4% reported using the Internet and social networks. Thus, it is crucial that resources like social media are reliable and provide valuable information. Q3 revealed the lack of time to follow up the diet after diagnosis (48% of HCPs allocate < 15 min), the interest in further training, and the need for a professional specialized in diets within the healthcare system. In conclusion, it is essential to enhance nutritional education to increase awareness of a GFD.

In our editorial, we want to comment on the article by Stefanolo et al titled "Effect of Aspergillus niger prolyl endopeptidase in patients with celiac disease on a long-term gluten-free diet". Celiac disease is an immune-mediated disorder triggered by dietary gluten in genetically predisposed individuals. Although avoiding gluten can permit patients to live symptom-free, ongoing voluntary or involuntary exposure to gluten is common and associated with persistent villous atrophy in small bowel mucosa. As villous atrophy predisposes patients to life threatening complications, such as osteoporotic fractures or malignancies, therapeutic adjuncts to gluten-free diet become important to improve patients' quality of life and, if these adjuncts can be shown to improve villous atrophy, avoid complications. Oral administration of enzyme preparations, such as endopeptidases that digest gluten and mitigate its antigenicity to trigger inflammation, is one clinical strategy under investigation. The article is about the utility of one endopeptidase isolated from Aspergillus niger. We critique findings of this clinical trial and also summarize endopeptidase-based as well as other strategies and how they can complement gluten-free diet in the management of celiac disease.

INTRODUCTION: Celiac disease is a disease triggered by a protein called gluten. Celiac disease has intestinal and extraintestinal manifestations. Bronchiectasis is a permanent dilation of the bronchi that causes symptoms, such as cough producing a large amount of sputum, recurrent respiratory infections, and breathlessness. In addition, bronchiectasis can present in 60% of cases with chronic rhinosinusitis. CASE PRESENTATION: A 40-year-old Arab woman presented with a worsening old cough with an increased amount of sputum; the patient was diagnosed with Celiac disease 7 months prior. Investigations started with laboratory tests followed by a computed tomography scan for the head and chest, bronchoscopy, bronchoalveolar lavage, and spirometry; the final diagnosis was bronchiectasis with chronic rhinosinusitis. She was advised to commit to the gluten-free diet, in addition to the medications prescribed for her bronchiectasis and chronic rhinosinusitis. CONCLUSION: Celiac disease and bronchiectasis might share an immunologic disturbance that caused both entities, so Celiac disease should be kept in mind as an etiology for pulmonary diseases.

Gluten-free bread is increasingly popular among individuals with celiac disease, and The incorporation of mushroom flour offers a novel method to enhance its nutritional profile, antioxidant content, and sensory properties. This study aimed to evaluate the antioxidant and sensory characteristics of gluten-free bread with varying amounts of chaga mushroom flour (5%, 10%, 15%, 20%). The total contents of polyphenols and flavonoids were measured using a spectrophotometric method. Antioxidant activity was assessed through DPPH and FRAP methods, while textural properties were evaluated using the TPA test. Bread colour was analysed using the CIELab system, and sensory evaluation was performed by a panel of trained consumers. The results showed that gluten-free bread enriched with chaga flour had increased polyphenol and flavonoid content and enhanced antioxidant activity. The highest levels of polyphenols, flavonoids, DPPH, and FRAP activity were found in bread with 20% chaga. The addition of chaga mushroom significantly affected the bread's hardness, cohesiveness, and chewiness. Specifically, 20% chaga flour had the most pronounced effect on hardness and elasticity, while 15% chaga flour had the greatest impact on chewiness and cohesiveness. The bread's colour darkened with higher chaga concentrations. The results of sensory evaluation showed a negative correlation between consumer preferences and bread fortified with chaga mushroom flour. The overall consumer acceptability score indicates that only a small addition of mushroom flour (up to 10%) can be used to bake gluten-free bread.

BACKGROUND: Data on resilience, the ability to recover from adversity, in coeliac disease (CeD) are lacking. AIM: To assess the degree of resilience in patients with CeD on a gluten-free diet (GFD), and its association with clinical features, sociodemographic factors, psychological morbidity, and quality of life (QOL). METHODS: A cross-sectional multicentre Italian study was conducted on adult CeD patients between May 2022 and April 2023. Connor-Davidson Resilience Scale (CD-RISC), the Coeliac Disease-specific Quality of Life Scale (CD-QOL), the State-Trait Anxiety Inventory scale (STAI-Y), and the Beck Depression Inventory scale (BDI) were used to evaluate resilience, QOL, anxiety, and depression, respectively. A multivariate analysis was conducted to identify factors independently associated with the degree of resilience. RESULTS: A total of 305 patients (221 F, mean age at CeD diagnosis 36 ± 16 years) on a long-term GFD (median 8 years, IQR 3-17) were enrolled. A total of 298/305 patients (98%) had a high level of resilience (CD-RISC ≥ 35). At univariate analysis, resilience was statistically associated with male gender (p = 0.03), age at enrolment (p = 0.02), marital status (p = 0.03), QOL (p < 0.001), anxiety (p < 0.001), and depression (p < 0.001). On multivariate regression analysis, trait anxiety (STAI-Y2, p < 0.001) and depression (BDI, p = 0.02) were independent predictors of lower levels of resilience. CONCLUSIONS: Higher trait anxiety predicts lower levels of resilience. Targeted interventions in this subgroup of patients may be helpful for their management and follow-up.

This systematic review aimed to find the tool that best predicts celiac individuals' adherence to a gluten-free diet (GFD). The Transparent Reporting of Multivariable Prediction Models for Individual Prognosis or Diagnosis (TRIPOD-SRMA) guideline was used for the construction and collection of data from eight scientific databases (PubMed, EMBASE, LILACS, Web of Science, LIVIVO, SCOPUS, Google Scholar, and Proquest) on 16 November 2023. The inclusion criteria were studies involving individuals with celiac disease (CD) who were over 18 years old and on a GFD for at least six months, using a questionnaire to predict adherence to a GFD, and comparing it with laboratory tests (serological tests, gluten immunogenic peptide-GIP, or biopsy). Review articles, book chapters, and studies without sufficient data were excluded. The Checklist for Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modeling Studies (CHARMS) was used for data collection from the selected primary studies, and their risk of bias and quality was assessed using the Prediction Risk of Bias Assessment Tool (PROBAST). The association between the GFD adherence determined by the tool and laboratory test was assessed using the phi contingency coefficient. The studies included in this review used four different tools to evaluate GFD adherence: BIAGI score, Coeliac Dietary Adherence Test (CDAT), self-report questions, and interviews. The comparison method most often used was biopsy (n = 19; 59.3%), followed by serology (n = 14; 43.7%) and gluten immunogenic peptides (GIPs) (n = 4; 12.5%). There were no significant differences between the interview, self-report, and BIAGI tools used to evaluate GFD adherence. These tools were better associated with GFD adherence than the CDAT. Considering their cost, application time, and prediction capacity, the self-report and BIAGI were the preferred tools for evaluating GFD adherence.

BACKGROUND/AIMS: This study is aimed to compare the effects of nutrition which has been enriched with different amounts of gluten to gluten-free diets on weight gain, diabetogenic state, hematological, and biochemical parameters. MATERIALS AND METHODS: A total of 40 newly weaned male Wistar albino rats used in the study were randomized into 4 different groups based on the gluten rations they were given. Following 12 weeks of diet they were killed and intracardiac blood samples were collected. Groups were identified as group 1 (n = 10): control group; normal rat ration containing wheat, group 2 (n = 10): gluten-free diet, group 3 (n = 10): ration containing medium level of gluten (normal rat diet+6% vital gluten) and group 4 (n = 10): ration containing high level of gluten (normal rat diet+12% vital gluten). RESULTS: In groups 3 and 4, high-density lipoprotein was found to be higher than the other 2groups. However, when group 2 results were compared to the other groups; the highest T3, T4, creatinine and B12 levels and the lowest gluten-specific IgE level were observed. alanine aminotransferase and aspartate aminotransferase levels were found to be higher in group 1 compared to the other 3 groups. No statistically significant difference was detected between the groups in terms of other parameters. CONCLUSION: This study provides evidence that a gluten-containing diet does not cause weight gain, has no diabetogenic effect, and also does not adversely affect general health in relation to hematological, biochemical, and various endocrinological parameters.

We comment here on the article by Stefanolo et al entitled "Effect of Aspergillus niger prolyl endopeptidase in patients with celiac disease on a long-term gluten-free diet", published in the World Journal of Gastroenterology. Celiac disease is a well-recognized systemic autoimmune disorder. In genetically susceptible people, the most evident damage is located in the small intestine, and is caused and worsened by the ingestion of gluten. For that reason, celiac patients adopt a gluten-free diet (GFD), but it has some limitations, and it does not prevent re-exposure to gluten. Research aims to develop adjuvant therapies, and one of the most studied alternatives is supplementation with Aspergillus niger prolyl endopeptidase protease (AN-PEP), which is able to degrade gluten in the stomach, reducing its concentration in the small intestine. The study found a high adherence to the GFD, but did not address AN-PEP as a gluten immunogenic peptide reducer, as it was only tested in patients following a GFD and not in gluten-exposing conditions. This study opens up new research perspectives in this area and shows that further study is needed to clarify the points that are still in doubt.

Celiac disease (CD) is a chronic autoimmune disorder triggered by the ingestion of gluten-containing food by genetically predisposed individuals. Hence, treatment of CD consists of permanent avoidance of wheat, rye, barley, and other gluten-containing foods. Lifelong adherence to a gluten-free diet (GFD) improves the symptoms of CD, but recent evidence suggests it is also associated with a higher risk for hepatic steatosis and the coexistence or emergence of other cardiometabolic risk factors. Moreover, a higher risk for liver steatosis is also reported by some authors as a potential extraintestinal complication of the CD itself. Recent nomenclature changes designate the association between hepatic steatosis and at least one of five cardiometabolic risk factors as metabolic dysfunction-associated steatotic liver disease (MASLD). An extended network of potentially causative factors underlying the association between MAFLD and CD, before and after dietary therapy is implemented, was recently described. The individualized treatment of these patients is less supported by evidence, with most of the current recommendations relying on empiric clinical judgment. This review focuses on the causative associations between CD and hepatic injury, either as an extraintestinal manifestation of CD or a side effect of GFD, also referring to potential therapeutic strategies for these individuals.

A Caucasian male in his 60s presented with acute onset of dizziness, dysarthria, and gait ataxia. Upon extensive workup, positive findings were cerebrospinal fluid (CSF) showing lymphocytic pleocytosis with oligoclonal bands, positive celiac disease autoantibodies in blood, a duodenal biopsy indicating lymphocytic infiltration, and positive anti-mGluR1 antibody titers in CSF. The patient was started on a strict gluten-free diet and intravenous immunoglobulin therapy for 5 days and showed mild consecutive improvements each day of treatment. He was discharged after 22 days, and was encouraged to continue gluten adherence, physical and speech therapy, and follow up with neuroimmunology. This report demonstrates that autoimmune encephalitis due to anti-mGluR1antibodies and gluten ataxia are both immune-mediated disorders that should be considered in acute cerebellar ataxia cases. By broadening the differential diagnosis and a comprehensive CSF analysis, identification of gluten ataxia and autoimmune encephalitis were beneficial in the management of this particular patient.

Celiac disease - a prevalent food intolerance - requires strict adherence to a lifelong gluten-free (GF) diet as the only effective treatment. However, GF products often lack soluble fibre and have a high glycaemic index. Consequently, there is a pressing need in the food industry to develop GF products with improved nutritional profiles. In this context, the impact of incorporating orange peel flour (OPF) into muffins undergoing sourdough fermentation was examined, focusing on their technological, antioxidant, and nutritional characteristics. The functional properties of OPF were investigated using human colon carcinoma HCT8 cells as a model system. Treatment with OPF extract demonstrated a notable reduction in malignant cell viability and intracellular ROS levels, indicating potent antioxidant capabilities. Western blot analysis revealed significant alterations in key signalling pathways, including increased phosphorylation of NF-kB at serine 536 and reduced intracellular levels of caspase-3, alongside increased phosphorylation of RIPK3 and MLKL, suggesting potential involvement in necroptosis. OPF incorporation in muffins with sourdough increased antioxidant activity, reduced glycaemic index, and affected the volatile profile. Furthermore, based on simulated colonic fermentation, muffins with OPF showed a slight prebiotic effect, supported by the significant increase in bacillus-shaped lactic acid bacteria and Clostridia population. Overall, OPF-enriched muffins demonstrated considerable antioxidant effects and impacts on cell viability, underscoring their potential as functional ingredients in GF products. These findings signify the prospect of OPF enhancing the nutritional profiles and conferring health benefits of GF muffins.

Low bone mineral density (BMD) is common in adults with coeliac disease (CD), even in individuals adhering to a gluten-free diet (GFD). Women are more likely to have low BMD and have an increased risk of osteoporosis, so women with pre-existing low BMD related to CD are at an even higher risk. BMD assessed by dual X-ray absorptiometry (DXA) and bone quality assessed through quantitative ultrasound (QUS) were investigated in 31 premenopausal women with CD consuming a GFD, and 39 matched healthy controls from the Lower North Island, New Zealand. In addition, bone metabolism and nutrient status were assessed, and four-day diet diaries were used to estimate nutrient intake. No statistically significant differences were found in BMD assessed by DXA between the two groups at the hip, lumbar spine or forearm. However, the parameters measured by the QUS were significantly lower in CD participants. Dietary data indicated significantly lower intakes of energy, dietary fibre, magnesium and phosphorus in women with CD, likely as a result of a reduced intake of wholegrain foods, and suggested that both groups had inadequate intake of calcium. No significant differences were demonstrated in biochemical parameters. BMD and bone biomarkers indicated no differences between coeliac and healthy women in New Zealand. However, these findings suggest that QUS may be more sensitive for the coeliac population, due to the disease's affect on the trabecular bone, and warrant further research.

This cross-sectional study aimed to estimate the relationship between food insecurity (FI) and health-related quality of life (HRQoL) in patients with celiac disease (CD) and assess whether this relationship is mediated or moderated by adherence to the gluten-free diet (GFD). The results of 1162 samples of patients diagnosed with CD showed that 8.3% of individuals who have a combined score of less than 13 exhibited excellent or very good adherence to the GFD. Furthermore, moderate and fair to poor adherence to the GFD was demonstrated, respectively and 71.9% of the patients had poor HRQoL levels. A significant and moderate positive correlation between FI and GFD adherence (r = 0.489) was found, indicating that 24% of the variance in FI is shared with GFD adherence. The patients' gender, marital status, and monthly income made statistically significant contributions to the prediction (p < 0.05). Females had significantly lower HRQoL scores than males (B = -4.619, 95% CL: -6.08, -3.16) after holding all other variables constant. In conclusion, FI is mediated by GFD adherence to HRQoL. Moreover, a significant total effect relation was found between HRQoL and both FI and GFD adherence, suggesting that lowering symptoms and complications associated with CD may reduce the impact of FI on HRQoL.

INTRODUCTION: The exposome concept includes nutrition as it significantly influences human health, impacting the onset and progression of diseases. Gluten-containing wheat products are an essential source of energy for the world's population. However, a rising number of non-celiac healthy individuals tend to reduce or completely avoid gluten-containing cereals for health reasons. AIM AND METHODS: This prospective interventional human study aimed to investigate whether short-term gluten avoidance improves cardiovascular endpoints and quality of life (QoL) in healthy volunteers. A cohort of 27 participants followed a strict gluten-free diet (GFD) for four weeks. Endothelial function measured by flow-mediated vasodilation (FMD), blood testing, plasma proteomics (Olink®) and QoL as measured by the World Health Organisation Quality-of-Life (WHOQOL) survey were investigated. RESULTS: GFD resulted in decreased leucocyte count and C-reactive protein levels along with a trend of reduced inflammation biomarkers determined by plasma proteomics. A positive trend indicated improvement in FMD, whereas other cardiovascular endpoints remained unchanged. In addition, no improvement in QoL was observed. CONCLUSION: In healthy individuals, a short-term GFD demonstrated anti-inflammatory effects but did not result in overall cardiovascular improvement or enhanced quality of life.

A high number of varieties from corn (Zea mays L.) have been consumed for long time all over the world, however pigmented varieties are recently gaining renewed attention due to their beneficial effects and polyphenolic content. The natural lack of gluten makes corn suitable for consumption by celiac population, who need to control their inflammatory state through an appropriate gluten-free diet. The biological effects of polyphenols from pigmented corn are poorly investigated in the context of celiac disease. In this work, we analyzed through HPLC-DAD the phenolic composition of two Italian purple and red varieties ("Scagliolo Rosso" and "Rostrato di Rovetta", respectively) comparing their effects in human intestinal epithelial cells (CaCo-2 cells). The possible impact of gastro-intestinal digestion following oral consumption was assessed as well. The phenolic profile showed the presence of phenolic acids in both varieties, while anthocyanins were identified in Scagliolo Rosso only. After simulated digestion, the level of polyphenols did not significantly change and paralleled with an increased scavenging activity. In CaCo-2 cells, stimulated by a proinflammatory cocktail containing gliadin-derived peptides (IL-1ß, IFN-γ, digested gliadin), pigmented corn extracts inhibited the release of CXCL-10 and sICAM-1, with mechanisms partially ascribed to NF-κB impairment. At the same concentration (200 µg/mL), ROS production and catalase depletion were reverted through Nrf-2-independent mechanisms. Our data suggest that polyphenols from pigmented corns might help in controlling the inflammatory and oxidative state of people with celiac disease at intestinal level, at concentrations potentially achievable through a gluten-free diet.
