Abstract
AIM Apart from various typical gastrointestinal symptoms, coeliac disease may have its clinical manifestations in the oral cavity which is the entrance of the gastrointestinal tract. METHODS A systematic review of literature was performed using the following databases: Medline, Scopus, EBSCOhost and Cochrane Library for Systematic Review. INCLUSION CRITERIA observational or experimental original studies published in English with full text available between January 2000 and December 2022, regarding children and adolescents under the age of 20. Risk of bias was determined with the use of Risk Of Bias In Non-randomised Studies of Exposure. RESULTS Thirty-four studies were included in the review. The analysis confirmed a higher prevalence of numerous oral manifestations in coeliac disease concerning both hard and soft tissues. Our study found the prevalence of dental enamel defects to be at the level of 17.9%-83.5% (P value <0.047) and recurrent aphthous stomatitis of 8.3%-69% (P value <0.039). CONCLUSION Oral manifestations may precede gastrointestinal symptoms. Patients presenting such manifestations should be screened for coeliac disease. The cooperation of gastroenterologists and dentists could lead to an increased detectability of coeliac disease.

Abstract
International trends indicate that celiac disease (CeD) is becoming more common, while the clinical presentation of CeD tends to change. We aimed to investigate factors associated with the clinical presentation of CeD. We reviewed all CeD cases diagnosed at our tertiary center, University of Pécs (Hungary), between 1992 and 2019. We collected data of verified CeD patients on clinical presentations (classified by the Oslo Classification), the age at and calendar year of diagnosis, and sex, serology and histology at diagnosis. To assess the associations of baseline variables with clinical presentations, we applied univariate and multivariate (binary logistic regression) statistics. A total of 738 CeD patients were eligible for inclusion. In the univariate analysis, patients with classical CeD were more common in the latest calendar period (p < 0.001) and tended to be older (p = 0.056), but we failed to observe a significant association between the clinical presentation and sex, serology or histology at diagnosis. In the multivariate analysis, only age at diagnosis and calendar year were independently associated with clinical presentations (OR = 1.02, CI: 1.01-1.04 and OR = 0.93, CI: 0.89-0.98, respectively). Our findings confirmed that classical CeD is independently associated with age at diagnosis and calendar year of diagnosis of CeD, whereas other parameters were not significantly associated with clinical presentations.

Abstract
BACKGROUND The description of the clinical presentation of celiac disease (CeD) has usually come from studies at referral centers. Data about CeD presentation in the community are sparse. AIMS We aim to describe the clinical presentation of patients with biopsy-proven CeD at a community-based adult gastroenterology practice and compare it to a referral center. METHODS We performed a retrospective study of two cohorts of patients diagnosed with CeD between 2000-2007 (n = 117) and 2013-2016 (n = 91) in a community practice, and a third cohort (n = 188) diagnosed between 2000 and 2007 in a tertiary referral center. The clinical presentation, body mass index, tissue-transglutaminase levels, DEXA scan, vitamin D levels, and vaccine recommendations were assessed. RESULTS Celiac disease presentation changed over time in the two community cohorts. Recently, fewer patients presented with diarrhea and anemia, but constipation and neurologic symptoms were more common. The most recent cohort had a higher proportion of patients who were overweight or obese than the first cohort. However, the body mass index in both community cohorts was higher than in the tertiary referral center. The frequency of osteopenia and osteoporosis was high in both community cohorts. The tertiary referral center patients were younger, presented with a higher proportion of diarrhea and a lower body mass index. CONCLUSIONS The clinical presentation of CeD differs between the community setting and a tertiary referral center. Patients with CeD presenting to the community setting tended to be older, overweight, and to have a high proportion of mineral bone disease.

Abstract
BACKGROUND AND AIM Liver involvement in celiac disease (CeD) is known but its various etiologies and the effect of gluten free diet (GFD) on it is understudied. METHODS We searched PubMed, Medline and Embase databases from date of inception to March 7, 2022, to look for studies reporting on CeD and liver abnormalities. Pooled proportion of CeD patients with deranged transaminases, etiologies of various other liver diseases with CeD and the response to GFD were estimated. Subgroup analyses based on the age group, geographic distribution and duration of GFD were also carried out. RESULTS Total 42 studies (8976 patients) reported hyper-transaminasemia in patients with celiac disease. The pooled proportion of patients with elevated transaminases was 21.42% (95% CI: 17.02-26.59, I2 = 94%) overall, with similar prevalence among adults (21.20%) and children (21.51%). The commonest etiology was celiac hepatitis at 49.23% (95% CI: 30.09-68.59, I2 = 87%). Compliance with GFD was noted in 90.27%. The proportion of CeD patients with liver abnormalities who showed response to GFD was 86.39% (95% CI: 80.04-90.95, I2 = 74%) overall. CONCLUSION Liver involvement was noted in 21.42% of CeD patients. Celiac hepatitis was reported in nearly half of them. Good compliance and response were noted with GFD.

Prevalence of celiac disease in patients with liver diseases: a systematic review and meta-analyses. Am J Gastroenterol 2022; 118:820-832.

Abstract
OBJECTIVES A subset of patients with celiac disease (CeD) have liver involvement in the form of hypertransaminasemia, liver cirrhosis and autoimmune hepatitis. We conducted a systematic review with meta-analyses to determine pooled prevalence of CeD in patients with cryptogenic cirrhosis, all-cause cirrhosis, cryptogenic hypertransaminasemia, and all-cause hypertransaminasemia. METHODS We searched PubMed and EMBASE up to January 2022. Cross-sectional, case-control and prospective cohort studies performing serological tests and/or intestinal biopsy for CeD on patients with cryptogenic cirrhosis, all-cause cirrhosis, cryptogenic hypertransaminasemia and all-cause hypertransaminasemia were included, to calculate pooled estimates of seroprevalence and prevalence of biopsy-confirmed CeD in these four groups. RESULTS Of 6,871 articles screened, 20 articles were included finally in three meta-analyses for cryptogenic cirrhosis, all-cause cirrhosis and cryptogenic hypertransaminasemia. For the all-cause hypertransaminasemia group, a qualitative review of four studies was done instead of a meta-analysis, due to significant differences in studies. The pooled prevalence (95%CI) of biopsy-confirmed CeD, in cryptogenic cirrhosis was 4.6%(2.2-7.5%) while pooled prevalence of biopsy-confirmed CeD in all-cause cirrhosis was 0.8%(0-3.4%). Pooled prevalence of biopsy-confirmed CeD in cryptogenic hypertransaminasemia was 5.7%(3.2-8.8%). CONCLUSIONS Nearly one in 20 patients each with cryptogenic cirrhosis and cryptogenic hypertransaminasemia have CeD, hence they should both be considered high-risk groups for CeD. While prevalence of CeD in all-cause cirrhosis is similar to that in general population, it may be worth screening them for CeD as liver pathology has potential for reversal in them.

Abstract
Objective: Celiac disease (CD) is a multifactorial immune-mediated enteropathy caused by a response to ingested gluten. The current available treatment for CD is lifelong gluten-free diet (GFD). This study was done to see the effect of GFD on Vitamin D levels and bone mass density in celiac patients. Methods: A prospective interventional study on newly diagnosed celiac patients was conducted in the Pediatrics department of a tertiary care teaching institute in 2 stages viz. on presentation and after 6 months of GFD. Anthropometric measurements, biochemical investigations, Vitamin D levels, and DEXA scan was done at recruitment and after 6 months of GFD and was analyzed. Results: In newly diagnosed 60 pediatric celiac patients, positive effect of GFD on anthropometry, hemoglobin, Vitamin D levels, DEXA scan parameters was observed. Significant difference was found in Vitamin D levels which increased from baseline 14.85 ± 5.39 to 18.22 ± 5.67 ng/ml after 6 months of GFD (P < 0.05). Significant difference was found in BMD (mean Z-score) which increased from -0.941 ± 0.738 to -0.640 ± 0.60 after 6 months of GFD (P < 0.001). Conclusion: Our study concluded that there is significant increase in vitamin D levels as well as Z-score, bone mass density (BMD) and bone Mass Content (BMC) after 6 months of GFD.

Abstract
BACKGROUND Growth retardation is an important feature of celiac disease (CeD) that can lead to the failure of attainment of potential adult height. There is lack of data on the spectrum of height in treatment-naïve patients with CeD, with normal expected height at one end and short stature at the other. METHODS We performed a retrospective analysis of a prospectively maintained database at our center, including a total of 583 treatment-naïve patients with CeD: 419 adults (183 [43.7%] males) and 164 adolescents (12-18 years) (72 [43.9%] males). The details extracted from the database included demographic details, height, weight, body mass index, clinical symptoms, biochemical parameters, anti-tissue transglutaminase antibody anti-tTG Ab) titer, and the severity of villous abnormalities (as per modified Marsh grade). The data from Indian National Family Health Survey-4 were used as comparators. RESULTS Overall, 19.6% of adults and 57.9% of adolescents with CeD had short stature. While mean height of men with CeD was similar, women were taller than population controls. While a higher proportion of men with CeD had short stature as compared to the controls (32.2% vs. 20%, p<0.001), a lower proportion of women with CeD had short stature (9.7% vs. 18.9%, p<0.001). Higher proportion of adolescents with CeD had short stature compared to adults (57.9% vs. 19.6%, p<0.001). On multivariate analysis, adulthood was found to be associated with a lower prevalence of short stature. CONCLUSIONS Overall, 19.6% of adults and 57.9% of adolescents with CeD had short stature. While the mean height of adult men with CeD was not significantly different from the population controls, women were taller. Adolescents with CeD were significantly shorter than their peers.

Abstract
Celiac disease (CeD) is a systemic, immune-mediated enteropathy, which is triggered by gluten protein in genetically susceptible individuals. CeD, once thought to be an uncommon disease, is now recognized to affect approximately 40-60 million people globally. While CeD is now well reported from a few Asian countries such as India, China, Pakistan, and Middle Eastern countries; it is still believed to be uncommon in the rest of Asia. Gluten-related diseases other than CeD, like non-celiac gluten sensitivity (NCGS) are also emerging globally. CeD and NCGS may present with either intestinal or extra-intestinal symptoms, and a proportion of them have overlapping symptoms with irritable bowel syndrome. Hence, many of them are misdiagnosed as having irritable bowel syndrome in clinical practice. In this review, we discuss the emergence of CeD and other gluten-related disorders, both globally and in Asia, the overlapping manifestations between gluten-related disorders and irritable bowel syndrome, and the challenges associated with diagnosis and management of CeD in Asia.

Abstract
The frequency of celiac disease (CD) has increased along time, with relevant changes reported in geographical variations, clinical presentation and nutritional repercussions. In recent years, some celiac patients are presenting overweight/obesity, but it is unclear how frequent this is and to what extent undernutrition remains a concern. This is relevant because CD tends to be overlooked in overweight patients. With this in mind, we assessed age at diagnosis, clinical characteristics and nutritional status of 155 celiac patients diagnosed between 1994–2017 in four pediatric hospitals in Santiago, Chile. Since 2003, the number of patients diagnosed has increased (p < 0.0033), coinciding with antitransglutaminase and antiendomysial antibodies becoming available to public health systems. In 2000, 4.5% of patients were asymptomatic at diagnosis, suggesting that active search is not routinely applied. Gastrointestinal symptoms plus failure to thrive were significantly more frequent under 2 years (p = 0.0001). Nutritional status has improved at diagnosis and during follow up, but undernutrition remains more frequent in children <2 and <5 years (p < 0.002 and p < 0.0036, respectively). Overweight at diagnosis was reported in 2002 and obesity in 2010. After initiating treatment, since 2010, patients changing from undernourishment to overweight has sometimes been observed after only 6 months on a gluten-free diet.

Abstract
Up until the 1960s and 1970s, diarrhea, malabsorption syndrome, and failure to thrive were the presenting symptoms and signs of celiac disease (CD) in young infants; however this disease was also at the same time reported to be disappearing. Indeed, clinical childhood CD was seen to transform into a milder form, resulting in an upward shift in age at diagnosis during the 1970s (and years later for many countries). This changing pattern of CD presentation then altered the epidemiology of the disease, with major differences between and within countries observed. An awareness of the changing clinical nature of CD and use of case-finding tools to detect even clinically silent CD became an important factor in this changing epidemiology. Countries report both low and high prevalence but it seems to be on the increase resulting in a population-based level of 1-2%. This paper discusses the potential causes and environmental factors behind these observed clinical changes, identifying new clues from different studies published at the time this transformation took place. For instance, it was found that breastfeeding postponed the diagnosis of the disease but did not altogether prevent it. Moreover, gluten introduction at a young age, specifically at the mean age of 2 months, seemed to also have a clear impact in inducing malabsorption syndrome and failure to thrive in young infants in addition to other factors such as gluten intake volume and type of cereal present in the weaning food. Further, the impact of cow's milk and its high osmolarity might have played an important role; humanized milk formulas were not yet invented. Future epidemiological studies on the contributing environmental factors to the shift in CD presentation are thus recommended for countries in which these changing clinical features are still being observed.

Abstract
BACKGROUND Alopecia areata (AA) is a common autoimmune alopecia with heterogeneous severity and distribution. Previous studies found conflicting results about AA epidemiology. OBJECTIVE To determine the prevalence, incidence, and predictors of AA, alopecia totalis, alopecia ophiasis, and alopecia universalis. METHODS A systematic review of all published cohort and cross-sectional studies that analyzed AA and its subtypes. MEDLINE, Embase, LILACS, Scopus, Cochrane Library, and GREAT were searched. At least 2 reviewers performed study title/abstract review and data extraction. Random-effects meta-analysis was used because of significant heterogeneity (I2 = 99.97%). RESULTS Ninety-four studies met the inclusion criteria. The pooled prevalence (95% confidence interval, N) of AA overall was 2.11% (1.82-2.42, N = 302,157,365), with differences of population-based (0.75% [0.49-1.06%], N = 301,173,403) and clinic-based (3.47% [3.01-3.96], N = 983,962) studies. The prevalences of alopecia totalis, ophiasis, and universalis were 0.08% (0.04-0.13, N = 1,088,149), 0.02% (0.00-0.06, N = 1,075,203), and 0.03% (0.01-0.06, N = 1,085,444), respectively. AA prevalence (95% confidence interval) increased over time (<2000: 1.02% [0.85-1.22]; 2000-2009: 1.76% [1.51-2.03]; >2009: 3.22% [2.59-3.92]; P < .0001) and differed by region. AA prevalence was significantly lower in adults (1.47% [1.18-1.80]) than children (1.92% [1.31-2.65]; P < .0001). CONCLUSIONS AA affects 2% of the global population. AA prevalence is lower in adults than children, is increasing over time, and significantly differs by region.

Abstract
Context: In the resource poor country like India it is difficult to get HLA screening and EMA testing in patients with celiac disease in small centres. Aims: To study the effect of gluten free diet on IgA tissue transglutaminase levels and various growth parameters in patients with celiac disease. Settings and Design: This was a prospective study conducted in the department of paediatrics of a tertiary referral hospital in north India in 3 stages viz. on presentation, after 3 months and 6 months of initial presentation. Materials and Methods: 392 patients with symptoms suggestive of celiac disease were screened for IgA tTG levels more than 10 folds of upper limit of normal. 50 cases (who followed up for 6 months regularly) were enrolled in the study. Spectrum of various growth and clinical parameters were also studied. Statistical analysis used: Statistical analysis was performed by the SPSS version 20.0. Data were checked for normality before statistical analysis. p value less than 0.05 was considered statistically significant. Results: 50 cases were enrolled in study. After initiation of gluten free diet, improvements were seen in various growth factors like height (12.71%) and weight (3.47 cm) after 6 months. Serum tTG(IgA) levels decreased to 94.88±55.35 U/mL from baseline level of 202±83.96 U/mL after 6 months. Conclusions: Gluten free diet has major role in improvement in growth parameters as well as anemia. So, early detection of celiac disease is an important step in prevention of morbidity associated with this chronic disease.

Abstract
Coeliac disease (CD) is an immune-mediated systemic disorder caused by the ingestion of gluten. In children, it may present with intestinal or extra-intestinal manifestations such as diarrhoea, weight loss, iron deficiency anaemia or faltering growth. Diagnosis is confirmed by small bowel biopsies showing histological changes consistent with enteropathy. In 2012, the European Society for Paediatric Gastroenterology, Hepatology and Nutrition revised the CD guidelines and suggested that, in a selective group of symptomatic children, CD can be diagnosed without the need for small-bowel biopsies. Management of CD is through strict adherence to a life-long gluten-free diet (GFD). CD is of great public health significance as its prevalence in developing countries has been found to be similar to that in developed countries. Early recognition and treatment improves prognosis. Patients and families require long term support to enable effective adherence to a GFD lifestyle. This alone can be challenging, but through support of health professionals and dietitians, can improve patient outcomes. In resource-limited settings medical professionals need to be creative in formulating cheaper and locally sourced gluten free options in close cooperation with the dietitians thereby ensuring availability of gluten free food items at affordable prices. In this paper, we gave an overview of the subject followed by authors' view to emphasize the need for improved awareness in resource-limited settings.

Abstract
BACKGROUND Celiac disease (CeD) requires a biopsy from the small intestine to confirm the diagnosis. Conventionally, duodenal bulb (D1) was avoided as a biopsy site due to histological confounding factors at this site. However, sometimes, the bulb mucosa is the only affected site. The aim of the present study was to assess changes in duodenal bulb histology and compare it to distal duodenal histology and to analyze whether the addition of duodenal bulb biopsy increases the diagnostic yield of the CeD. METHODS It was a prospective study comprising of 98 patients of CeD who were symptomatic clinically and had positive anti tissue transglutaminase (tTG) antibody. Endoscopically four mucosal biopsies were taken, two each from the bulb and distal duodenum, and morphology was graded as per modified Marsh grade. RESULTS Iron deficiency anemia (40%) was a most common clinical presentation followed by chronic diarrhea (30%). Sixty patients showed same Marsh grade and 38 showed different Marsh grade at both sites. Patients who were showing the difference in the Marsh grade at the two biopsy sites, in place of; descending duodenum showed higher grade in 24 patients while higher mucosal atrophy was documented in the bulb in 14 patients. No patient of CeD had isolated D1 involvement. In eight patients, the correct diagnosis of CeD could be made only because of bulb biopsy. CONCLUSION Majority of the patients had no classical symptoms. Different Marsh grade at the two biopsy sites was documented demonstrating the patchy distribution of CeD. Combining biopsy from both bulb and descending duodenum maximizes the diagnostic yield of the CeD.

Abstract
ABSTRACT BACKGROUND Previous evidence trying to assess the risk of celiac disease among dyspeptic patients has been inconclusive, showing in some cases notorious discrepancies. OBJECTIVE To determine the prevalence of celiac disease in patients with dyspepsia compared to healthy controls without dyspepsia. METHODS Adult patients under evaluation for dyspepsia were invited to participate. These patients were offered an upper gastrointestinal endoscopy with duodenal biopsies. On the other hand, asymptomatic adult volunteers who performed a preventive visit to their primary care physician were invited to participate and agreed to undertake an upper gastrointestinal endoscopy with duodenal biopsies as well. Those patients with histologic signs of villous atrophy were furtherly evaluated and serological tests were performed in order to determine celiac disease diagnosis. Celiac disease prevalence was compared between groups. RESULTS Overall, 320 patients with dyspepsia and 320 healthy controls were recruited. There were no significant differences in terms of gender or age between groups. Celiac disease diagnosis was made in 1.25% (4/320) of patients in the dyspepsia group versus 0.62% (2/320) in the control group. CONCLUSION Patients with dyspepsia who underwent routine duodenal biopsies did not show an increased risk for celiac disease when compared to healthy individuals.

Abstract
BACKGROUND & AIMS Celiac disease is a common disorder with a worldwide distribution, although the prevalence among different ethnicities varies. We aimed to measure the prevalence of duodenal villous atrophy among patients of different ethnicities throughout the United States. METHODS We performed a cross-sectional study of all patients who had duodenal biopsies submitted to a national pathology laboratory between January 2, 2008 and April 30, 2015. The prevalence of villous atrophy was calculated for the following ethnicities by using a previously published algorithm based on patient names: North Indian, South Indian, East Asian, Hispanic, Middle Eastern, Jewish, and other Americans. RESULTS Among all patients (n = 454,885), the median age was 53 years, and 66% were female. The overall prevalence of celiac disease was 1.74%. Compared with other Americans (n = 380,163; celiac disease prevalence, 1.83%), celiac disease prevalence was lower in patients of South Indian (n = 177, 0%; P = .08), East Asian (n = 4700, 0.15%; P ≤ .0001), and Hispanic (n = 31,491, 1.06%; P ≤ .0001) ethnicities. Celiac disease was more common in patients from the Punjab region (n = 617, 3.08%) than in patients from North India (n = 1195, 1.51%; P = .02). The prevalence of celiac disease among patients of Jewish (n = 17,806, 1.80%; P = .78) and Middle Eastern (n = 1903, 1.52%; P = .33) ethnicities was similar to that of other Americans. Among Jewish individuals (n = 17,806), the prevalence of celiac disease was 1.83% in Ashkenazi persons (n = 16,440) and 1.39% in Sephardic persons (n = 1366; P = .24). CONCLUSIONS Among patients undergoing duodenal biopsy, individuals from the Punjab region of India constitute the ethnic group in the United States with the highest prevalence of villous atrophy consistent with celiac disease. Compared with other Americans, villous atrophy prevalence on duodenal biopsy is significantly lower among U.S. residents of South Indian, East Asian, and Hispanic ancestry.

Abstract
Coeliac disease is a common disorder that can arise at any age and typically presents with a broad spectrum of symptoms. The disease is thought to be underdiagnosed, in part owing to the fact that coeliac disease is often characterized by associated conditions and extraintestinal manifestations that can misdirect and impede diagnosis. Some of these manifestations are direct consequences of autoimmunity, such as dermatitis herpetiformis or gluten ataxia, whereas others are indirectly related to inflammation and/or malabsorption including anaemia, osteoporosis, short stature and delayed puberty. Any organ from the central nervous system to joints, liver or teeth can be affected. In some cases, extraintestinal symptoms are the only clinical manifestations of coeliac disease or occur in conjunction with diarrhoea and malabsorptive symptoms. An increased awareness among medical practitioners of the variety of extraintestinal manifestations of coeliac disease is essential to improve diagnosis and treatment.

Abstract
BACKGROUND While adherence to gluten-free diet (GFD) is essential for effective control of celiac disease, the level of adherence to GFD may vary. We assessed the level of adherence to GFD and identified barriers to adherence in patients with celiac disease. METHODS Both treatment-naive and follow up patients with celiac disease were recruited from a celiac disease clinic. All the patients were assessed for symptom improvement using celiac symptom index (CSI), weight, and hemoglobin; adherence to GFD using detailed dietary history and food-labeled quiz questionnaire; identification of barriers to GFD using a self-administered 36-point questionnaire; and quality of life using a standard 36-item short form (SF36) questionnaire. RESULTS Among the patients who were already on GFD, only 53.3% maintained an excellent or good level of adherence, which increased to 92.4% at 6 months with repeated counseling. Among the treatment-naive patients, 64.8% maintained either excellent or good compliance at 1 month after first counseling, which increased to 96.3% at 6 months with repeated counseling. The most common barrier to adherence was non-availability of GFD. Certain barriers could be modified with repeated counseling and education. Response to GFD, as measured by CSI, gain in weight, and improvement in hemoglobin, was better in those having either excellent or good compliance to GFD compared to those who remained poorly adherent. CONCLUSIONS Repeated counseling increased the level of adherence to GFD.

Abstract
Until 1970s, celiac disease (CD) was considered to be an uncommon disease except in Western Europe. The global epidemiology of CD continues to evolve with improvement in the diagnostic tests, simplification of the diagnostic criteria and increase in awareness about the disease. The Asian region is currently at the crossroads of the frontier of knowledge and awareness of CD. In many Asian nations, CD is still considered to be either nonexistent or very rare. A notable exception is India, where CD has been well recognized, especially in the northern part, and 2 population-based studies have revealed a prevalence of 0.3-1.04%. Initial reports from Malaysia, China, Japan and Singapore suggest the existence of CD in these countries. Furthermore, a meta-analysis of the predisposing factors predicts a high probability of occurrence of CD in fair numbers in China. There are no formal reports on CD from Malaysia, Indonesia, Korea, Taiwan and many other nations in this region. With the impending CD epidemic in Asia, there are many challenges. Some of the efforts which are required include determination of prevalence of CD across the region, spreading of awareness among physicians and patients, training of dieticians for proper counseling and supervision of patients, creation of gluten-free food infrastructure in the food supply and creation of patient advocacy organizations. Although the absolute number of patients with CD at present is not very large, this number is expected to increase over the next few years/decades. It is thus appropriate that the medical community across Asia define the extent of the problem and get prepared to handle the impending CD epidemic.

Abstract
Though children with type 1 diabetes mellitus (T1DM) are often tall at the time of diagnosis, they may experience growth retardation, pubertal delay or both, which may be due to poor glycemic control, associated diseases or chronic complications. Factors affecting growth include: gender, genetic environment, age at diagnosis, diabetes duration, puberty, metabolic control, and status of growth hormone (GH), insulin-like growth factors (IGFs), and IGF binding proteins (IGFBPs). Insulin regulates expression of hepatic GH receptors, affects IGFs and IGFBPs synthesis by modulating GH postreceptor events, and significantly increases IGF-I bioactivity. Low portal insulin seen in T1DM leads to GH hypersecretion, low circulating IGF-I and IGFBP-3, and high circulating IGFBP-1. Newly diagnosed T1DM patients have decreased GHBP which can be restored with insulin therapy. Growth velocity should be appropriate for the age of the child/adolescent, and the mid-parental height. Height, weight and blood pressure (BP) should be measured and plotted on a growth chart at least 2-3 times a year. Puberty should also be assessed annually. Following precautions are to be taken in T1DM children: checking for pubertal onset and ensuring it is not delayed, testing early when growth falters (hypothyroidism/celiac disease/puberty/other conditions), aiming for best possible metabolic control (multidose regimens, regardless of type of insulin), and encouraging dietary calcium and protein, exposure to sunlight, Vitamin D supplements and exercise.

Abstract
OBJECTIVE Some of the conventional serological tests for coeliac disease (CD) are expensive, time-consuming and not readily available in developing countries, leading to a delay in diagnosis. Recently, point-of-care tests (POCT) have been manufactured and tested in Europe but have not been validated in our setting. We therefore aimed to study the diagnostic accuracy of the POCT 'Biocard' test in diagnosing CD in Indian children. DESIGN Cross-sectional study. SETTING Tertiary care centre in north India. PATIENTS Children, aged 2-18 years, with chronic diarrhoea, short stature or refractory anaemia underwent serological testing for CD with antiendomysial antibodies (AEA), antitissue transglutaminase (tTG) antibodies and Biocard test followed by duodenal biopsy irrespective of serological results. CD was diagnosed with positive AEA and duodenal biopsy showing >grade 2 changes using modified Marsh criteria. Those who were both AEA negative and had normal histology were considered CD negative. RESULTS Of 319 children who underwent the serological testing, 170 agreed for biopsy. Of these, 110 were diagnosed with CD and 30 were found to be CD negative. Remaining 30 had discordant AEA and histology results and were not included in analysis. Biocard test agreed with 92/110 positive and 27/30 negative diagnoses based on reference tests (83.6% sensitivity and 90% specificity). tTG was found to be 93.8% sensitive and 96.4% specific. CONCLUSIONS We successfully validated the POCT for CD in our setting. It could be used to increase case detection rates in developing countries with a large undiagnosed CD burden.

Abstract
Autoimmune diseases are a range of diseases in which the immune response to self-antigens results in damage or dysfunction of tissues. Autoimmune diseases can be systemic or can affect specific organs or body systems. For most autoimmune diseases there is a clear sex difference in prevalence, whereby females are generally more frequently affected than males. In this review, we consider gender differences in systemic and organ-specific autoimmune diseases, and we summarize human data that outlines the prevalence of common autoimmune diseases specific to adult males and females in countries commonly surveyed. We discuss possible mechanisms for sex specific differences including gender differences in immune response and organ vulnerability, reproductive capacity including pregnancy, sex hormones, genetic predisposition, parental inheritance, and epigenetics. Evidence demonstrates that gender has a significant influence on the development of autoimmune disease. Thus, considerations of gender should be at the forefront of all studies that attempt to define mechanisms that underpin autoimmune disease.

Abstract
BACKGROUND Data correlating anti-tissue transglutaminase (tTG) antibody titers with severity of duodenal involvement is limited. OBJECTIVE The aim of this study was to correlate IgA anti-tTG antibody titers with symptoms, anthropometric parameters, and duodenal histopathology. METHODS Consecutively diagnosed patients of celiac disease as per modified ESPGHAN criteria presenting over a year were enrolled. Demographic data, symptoms, weight-for-age z score (WAZ), height-for-age z score (HAZ), IgA anti-tTG titer, and duodenal histopathology graded as per modified Marsh criteria were recorded. Spearman rank correlation test was used for association between TTG age, WAZ, and HAZ. Receiver operating curve (ROC), sensitivity, specificity, negative predictive value, and positive predictive value were used to obtain anti-tTG cutoff value predictive of Marsh grade 3. RESULTS One hundred and forty-two patients with celiac disease were evaluated. tTG showed significant correlation with WAZ (r = 0.822, p = <0.001) and HAZ (r = 0.722, p = <0.001) but not with age (r = 0.202, p = 0.066). The median anti-tTG titers rose progressively with higher Marsh grade on histopathology (p = 0.001). The median anti-tTG titer was also significantly higher in patients with classic celiac disease as compared to non-diarrheal celiac disease (144 u/mL vs. 27, p = 0.02). Anti-tTG titer of 62.5 u/mL was strongly predictive of duodenal histology of Marsh grade 3a and higher with sensitivity, specificity, positive predictive value, and negative predictive value of 95.4 %, 98 %, 93.8 %, and 88.3 % respectively. CONCLUSIONS There is a significant correlation between IgA anti-tTG titers and anthropometric parameters and severity of duodenal histopathology. With further validation, strongly positive titers may be sufficient to predict severity of this disease.

Abstract
BACKGROUND AND AIM Once thought to be uncommon in Asia, coeliac disease (CD) is now being increasingly recognized in Asia–Pacific region. In many Asian nations, CD is still considered to be either nonexistent or very rare. In recognition of such heterogeneity of knowledge and awareness, the World Gastroenterology Organization and the Asian Pacific Association of Gastroenterology commissioned a working party to address the key issues in emergence of CD in Asia. METHODS A working group consisting of members from Asia–Pacific region, Europe, North America, and South America reviewed relevant existing literature with focus on those issues specific to Asia–Pacific region both in terms of what exists and what needs to be done. RESULTS The working group identified the gaps in epidemiology, diagnosis, and management of CD in Asian–Pacific region and recommended the following: to establish prevalence of CD across region, increase in awareness about CD among physicians and patients, and recognition of atypical manifestations of CD. The challenges such as variability in performance of serological tests, lack of population-specific cut-offs values for a positive test, need for expert dietitians for proper counseling and supervision of patients, need for gluten-free infrastructure in food supply and creation of patient advocacy organizations were also emphasized. CONCLUSIONS Although absolute number of patients with CD at present is not very large, this number is expected to increase over the next few years or decades. It is thus appropriate that medical community across the Asia–Pacific region define extent of problem and get prepared to handle impending epidemic of CD.

Abstract
Celiac disease is emerging in India and has become a public health problem. Almost 6-8 million Indians are estimated to have celiac disease. While there is a large pool of patients with celiac disease in India, until now, only a fraction of them have been diagnosed. With increasing awareness about celiac disease amongst health care providers and the general population, a massive increase in the number of patients with celiac disease is expected now and in the subsequent decade in India. While the number of patients with celiac disease is increasing, the country's preparedness towards the emerging epidemic of this disease is minimal. There are a number of issues, which requires urgent attention. Some of the key issues include increased awareness amongst health care professionals and the general public about the disease and its management, team-based management of patients with celiac disease, proper counseling and supervision of patients, training of dietitians in the management of patients with celiac disease, industrial production of reliable and affordable gluten-free food, and food labeling for gluten contents.

Abstract
Celiac disease (CD) is an immune-mediated disorder that may be associated with various diseases that share a similar pathogenic immune mechanism. This study reports on the prevalence of various diseases in a cohort of CD patients in northern India. Patients diagnosed with CD based on modified ESPGHAN criteria were prospectively evaluated for associated concomitant diseases. Of the 363 patients evaluated, 207 (57.0 %) were male. The mean age was 19 years. Seventy-one percent of patients presented with typical diarrheal disease, while 29 % presented with atypical nondiarrheal disease. One or more associated diseases were noted in 70 (19.2 %) patients. Liver diseases were the most common association. Portal hypertension was present in 33 (9 %) patients; chronic liver disease was the underlying cause in 17 patients, while noncirrhotic causes were noted in 16 patients. Type 1 diabetes was seen in 13 and hypothyroidism in 11 patients. Other unreported or rarely reported associated diseases were also found in some of the patients. Associated comorbid diseases are common, and may need to be actively screened, in Indian CD patients.
