Celiac disease: presentation of 109 children

Celiac Crisis: A Life-Threatening Complication of Celiac Disease

Celiac disease (CD) is an immune-mediated enteropathy with varied systemic involvement and association with increased morbidity and mortality. Strong clinical suspicion is the key, and diagnosis is made using histopathology and serology. Though the consumption of a strict gluten-free diet can improve symptoms and limit mucosal damage, curative therapy is still lacking. Significant clinical improvement can be seen after treatment with immunosuppressive therapy; however, there is no definitive role of immunosuppression in preventing complications. Celiac crisis (CC), a serious and life-threatening complication of CD, is characterized by acute onset and rapid progression of gastrointestinal manifestations associated with metabolic and electrolyte disturbances and neurological and renal dysfunction. Management comprises urgent hospitalization, fluid resuscitation, correction of electrolyte imbalance, and albumin infusion. Early identification and diagnosis of CD and timely initiation of a gluten-free diet with proper compliance are of paramount importance in preventing complications, including CC. Regular follow-up after diagnosis is a good approach to assessing adherence to the gluten-free diet, disease activity, and screening for complications. With the advent of improved diagnostic facilities and access to the health care system, timely diagnosis, and efficient management, prognosis has improved significantly in recent years.

Serum anti-mullerian hormone, sex hormone, and nutrient levels in reproductive age women with celiac disease

PURPOSE

This study aimed to investigate the changes in serum Anti-Müllerian Hormone (AMH) levels, sex hormone levels, follicle-stimulating hormone (FSH)/luteinizing hormone (LH) ratio in patients with celiac disease (CeD), and their correlation with clinical characteristics and nutrient levels.

METHODS

This cross-sectional study collected clinical and biochemical data from a total of 67 females diagnosed with CeD and 67 healthy females within the reproductive age range of 18-44 years. The study was conducted at a tertiary hospital between September 2016 and January 2024. Both groups underwent comprehensive clinical and laboratory assessments. Serum levels of AMH and sex hormones were quantified using chemiluminescence immunoassay, and their associations with CeD clinical features and nutrient levels were thoroughly analyzed.

RESULTS

The study included 67 patients and 67 controls with a mean age of 36.7±7.6 years. No statistically significant differences were found between the two groups in mean age, BMI, FSH, LH, E2, P levels, FSH/LH, menstrual irregularities, abortions history, parity, and gravidity (all P>0.05). However, AMH, T, FER, FA, Zn, and Se levels were significantly lower, and PRL levels were higher in the CeD group (all P<0.05). Spearman's correlation analysis showed that AMH levels were negatively correlated with age, tTG level, disease duration, and Marsh grading (P<0.05).

CONCLUSIONS

This study highlights the association between impaired ovarian function in CeD patients and disease severity and nutrient levels. Early detection and intervention for ovarian function abnormalities are imperative to enhance fertility potential in CeD patients.

Celiac disease and depressive disorders as nutritional implications related to common factors - A comprehensive review

Celiac disease (CD) is an immune-mediated disease affecting the small intestine. The only treatment strategy for CD is the gluten-free diet (GFD). One of the more common mental disorders in CD patients is major depressive disorder (MDD). The influence of GFD on the occurrence of MDD symptoms in patients with CD will be evaluated. This diet often reduces nutritional deficiencies in these patients and also helps to reduce depressive symptoms. Both disease entities are often dominated by the same deficiencies of nutrients such as iron, zinc, selenium, iodine, or B and D vitamins. Deficiencies of particular components in CD can favor MDD and vice versa. Gluten can adversely affect the mental state of patients without CD. Also, intestinal microbiota may play an important role in the described process. This work aims to comprehensively assess the common factors involved in the pathomechanisms of MDD and CD, with particular emphasis on nutrient imbalances. Given the complexity of both disease entities, and the many common links, more research related to improving mental health in these patients and the implementation of a GFD would need to be conducted, but it appears to be a viable pathway to improving the quality of life and health of people struggling with CD and MDD. Therefore, probiotics, micronutrients, macronutrients, and vitamin supplements are recommended to reduce the risk of MDD, given that they may alleviate the symptoms of both these disease entities. In turn, in patients with MDD, it is worth considering testing for CD.

Nutrient deficiencies in children with celiac disease during long term follow-up

BACKGROUND

Celiac disease (CD) is associated with malabsorption and consequential nutritional deficiencies. Patients with CD must follow a gluten-free diet (GFD), which is also associated with nutrient deficiencies. Despite the clinical significance, consensus is lacking on the pattern and frequency of nutrient deficiencies in CD and the usefulness of assessment during follow-up. The aim was to investigate the presence of micronutrient and protein deficiencies in pediatric patients with CD after starting a GFD and receiving standard clinical care, taking disease activity into account.

METHODS

This single center retrospective chart review aimed to map the occurrence of nutrient deficiencies, determined in serum samples derived during follow-up in an expertise center for pediatric CD. Serological micronutrient levels were determined during routine clinical visits up until 10 years in children with CD on a GFD.

RESULTS

The data of 130 children with CD was included. When pooling the measurements between 3 months and 10 years after GFD initiation, a deficiency in iron, ferritin, vitamin D, vitamin B12, folate and zinc was present in 33%, 21,9%, 21,1%, 2,4%, 4,3% and 8,1% of measurements, respectively. No hypocalcemia or vitamin B6 deficiency was found.

CONCLUSION

The prevalence of deficiency varies amongst nutrients in children following a GFD, a high prevalence of some nutrient deficiencies is noteworthy. This study highlights the necessity to structurally investigate the risk of developing nutrient deficiencies while following a GFD. Knowledge of the risk to develop deficiencies can contribute to achieving a more evidence based approach in the management and follow-up of CD in children.

Relationship between villous atrophy and Wnt pathway gene expressions in pediatric celiac patients

OBJECTIVE

Celiac disease is an autoimmune disease characterized by an abnormal immune response occurring in the small intestine linked to consumption of food containing gluten in individuals with a genetic predisposition. Dysregulation of Wnt signal transduction plays a role in the pathogenesis of many diseases including autoimmune diseases like celiac disease. In this study, the correlation of Wnt pathway gene expressions with each other and the correlation with clinical data were researched in pediatric celiac disease cases grouped according to the Marsh classification.

METHODS

Gene expression levels of FZD8, DVL2, LRP5, RHOA, CCND2, CXADR, and NFATC1, which are involved in the Wnt pathway, were determined using quantitative real-time polymerase chain reaction in 40 celiac disease and 30 healthy individuals.

RESULTS

All cases with the short height symptom were observed to be in Marsh 3b\3c groups (p=0.03). The gene expressions of DVL2, CCND2, and NFATC1 were high in the Marsh 3b group, and these genes showed positive correlation with each other (p=0.002). LRP5 and CXADR gene expressions were lower in the Marsh 3b group compared to other Marsh groups, and these genes showed a positive correlation with each other (p=0.003). CCND2 gene expression was associated with Marsh 3b group, diarrhea, and vomiting symptoms. DVL2 gene expression was correlated with Marsh 2 group and constipation symptom (p<0.05).

CONCLUSION

Wnt signaling in the early stages of the disease of Marsh 1-2 involves high expression of LRP5 and CXADR genes, while expression of these two genes reduces, and DVL2, CCND2, and NFATC1 gene expressions clearly increase with a transduction variation observed from Marsh 3a stage when villous atrophy begins to form. It appears that the Wnt pathway may contribute to disease progression through expression changes.

Association of Serum Albumin, Globulin, and Transferrin Levels in Children of Poorly Managed Celiac Disease

Background

Celiac disease (CD) is an autoimmune genetic disorder in which gluten protein causes inflammation of the intestinal enterocytes. CD diagnosis in most cases is delayed or mistreated due to its varied clinical features. We aimed to evaluate the protein profile imbalance in different CD groups of children, which could help aid in the diagnosis and proper management of the disease. Methodology. This was a cross-sectional study with a nonrandom purposive sampling technique. All samples were taken from tertiary care hospitals of Hyderabad, Pakistan. In total, there were 175 children (age 3-15 years) divided into five equal groups (n = 35), namely, group A (control), group B (celiac diagnosed), group C (celiac-like symptoms), group D (celiac with type 1 diabetes mellitus), and group E (type 1 diabetes mellitus only). Clinical symptoms and laboratory parameters were analyzed among all the groups. Sera proteins, albumin, globulins, and transferrin levels were evaluated and compared with healthy individuals.

Results

The albumin in serum of celiac groups B and C was 3.0 g/dl and 2.8 g/dl, respectively. While in diabetic patients with CD, it is 2.7 g/dl. The globulin levels were raised among all the celiac groups with typical GIT symptoms. The highest transferrin was observed in group B, celiac patients with severe anemia. Patients were not on GFD, hence had no or less recovery and had chronic symptoms of celiac.

Conclusion

The misdiagnosis and poor management of celiac leads to chronic villous atrophy with imbalance in metabolic profile. Serum analysis of albumin, globulins, and transferrin may help in the diagnosis and proper management of the disease to recover the celiac symptoms.

Liver abnormalities in celiac disease and response to gluten free diet: A systematic review and meta-analysis

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.

Characteristics of Children With Inflammatory Bowel Disease and Coexisting Celiac Disease Seropositivity

OBJECTIVES

Celiac disease (CeD) autoimmunity and coexisting inflammatory bowel disease (IBD) present a diagnostic dilemma. Our aims were to describe the phenotype of children with IBD and CeD seropositivity and evaluate provider confidence for diagnosing CeD in this population.

METHODS

We performed a single-center retrospective cohort study of subjects ≤18 years old with IBD and CeD seropositivity between 2006 and 2020. Subjects were considered to have IBD-CeD if they met CeD diagnosis by serology and histology per North American Society For Pediatric Gastroenterology, Hepatology and Nutrition guidelines and if providers suspected CeD as evaluated by a survey. The IBD-only cohort included seropositive participants that did not meet criteria for CeD. Demographic, histologic, gross endoscopic, and laboratory features were compared using Fisher exact test.

RESULTS

Of 475 children with IBD, 8 had concomitant CeD, 5 had tissue transglutaminase (tTG) immunoglobulin A (IgA) > 10x upper limit of normal (ULN, P = 0.006), and 8 had villous atrophy (VA, P = 0.003) when compared with 17 seropositive participants with IBD-only. No children with IBD-CeD had esophageal eosinophilia, duodenal cryptitis, duodenal ulceration, or fecal calprotectin >250 µg/g. Factors that contributed to provider uncertainty for diagnosing CeD in IBD included the absence of VA and intraepithelial lymphocytes, the presence of neutrophilic and eosinophilic duodenitis, diffuse ulceration, elevated inflammatory markers, and immunosuppression therapy.

CONCLUSIONS

Diagnosing CeD in children with IBD continues to be challenging. Although high titers of tTG IgA and VA increased provider confidence for diagnosing CeD in IBD, development of evidence-based guidelines are needed. They should better assess the importance of features atypical of concomitant CeD that contribute to uncertainty.

Serologic, endoscopic and pathologic findings in pediatric celiac disease: A single center experience in a low/middle income country

BACKGROUND

Studies in Africa, Asia, and Latin America are needed to provide a comprehensive picture of the global incidence of celiac disease (CD).

AIM

To describe the serology, endoscopic and histological findings in typical and atypical presentations of pediatric CD at a tertiary referral hospital in an African low/middle income country (LMIC).

METHODS

This observational study was conducted on 199 patients with CD from 2010 to 2019. The patients were divided into typical and atypical groups according to the presenting symptoms including 120 and 79 patients respectively. Serology, upper gastrointestinal endoscopy with duodenal biopsy were performed for patients who had symptoms suggestive of CD. The severity of the intestinal damage was graded according to the histo-pathologic Marsh-Oberhuber classification.

RESULTS

Chronic diarrhea was the main intestinal presentation in the typical group. Anemia was the most common extraintestinal symptom in both the typical and atypical group. Marsh-Oberhuber type 3b and 3c was significantly higher in the seropositive patients with a P value of 0.007. A significant correlation was observed between the histological grade of the biopsied duodenal mucosa and the clinical presentation (P < 0.001). Age was significantly higher in the atypical group (P value < 0.001).

CONCLUSION

Although typical CD was observed in 120 patients in this study, the clinical variability of the condition was frequently observed. Age only was a significant predictor for the appearance of atypical CD. Therefore, CD presentations in LMIC are not different from industrialized countries.

Iron Deficiency Anemia in Celiac Disease

The iron absorption process developsmainly in the proximal duodenum. This portion of the intestine is typically destroyed in celiac disease (CD), resulting in a reduction in absorption of iron and subsequent iron deficiency anemia (IDA). In fact, the most frequent extra-intestinal manifestation (EIM) of CD is IDA, with a prevalence between 12 and 82% (in relation with the various reports) in patients with new CD diagnosis. The primary treatment of CD is the gluten-free diet (GFD), which is associated with adequate management of IDA, if present. Iron replacement treatment historically has been based on oral products containing ferrous sulphate (FS). However, the absorption of FS is limited in patients with active CD and unpredictable in patients on a GFD. Furthermore, a poor tolerability of this kind of ferrous is particularly frequent in patients with CD or with other inflammatory bowel diseases. Normalization from anemic state typically occurs after at least 6 months of GFD, but the process can take up to 2 years for iron stores to replenish.

Zinc Deficiency in Men Over 50 and Its Implications in Prostate Disorders

Research has been consistently showing the role of zinc (Zn) in prostate function. In this article, we review the current literature on the anatomy and main functions of the prostate, highlighting the role of zinc. In particular, we will review the etiology of benign prostate enlargement (BPH), its prevalence in men over 50, the likelihood of BPH becoming prostate cancer (PCa), and explain the relationship of zinc and apoptosis in the prostate cells and the implications for BPH and PCa. We present a model that explains how endogenous factors provoke excretion of zinc or limit zinc absorption, and how exogenous factors like nutrition and drugs regularly used in men over 50 can significantly decrease zinc status and thereby increase the risk of BPH. Finally, we explain how Zn amino acid (AA) complexes may be capable of avoiding antagonists and inhibitors of zinc absorption, thereby increasing the bioavailability of zinc for the necessary biological processes in the prostate.

Persistent Iron Deficiency Anemia in Patients with Celiac Disease Despite a Gluten-Free Diet

Celiac disease (CD) is an autoimmune disorder characterized by intolerance to dietary gluten in genetically predisposed subjects. Iron deficiency anemia (IDA) is a common sign in CD, being the only abnormality in approximately 40% of celiac patients. A multifactorial etiology leads to IDA in CD. The two main causes are the villous atrophy of the mucosa at the site of iron absorption (the duodenum) and the resulting inflammation, which triggers the mechanism that leads to the anemia of chronic disease. Until now, it has been unclear why some patients with CD continue to have IDA despite a careful gluten-free diet (GFD) and the normalization of villous atrophy. Furthermore, some celiac patients are refractory to oral iron supplementation despite the healing of the mucosa, and they thus require periodic intravenous iron administration. The Marsh classification evaluates the degree of inflammation and villous atrophy, but it does not assess the possible persistence of ultrastructural and molecular alterations in enterocytes. The latter was found in CD in remission after adopting a GFD and could be responsible for the persistently reduced absorption of iron and IDA. Even in non-celiac gluten sensitivity, anemia is present in 18.5-22% of patients and appears to be related to ultrastructural and molecular alterations in intestinal microvilli. It is possible that a genetic component may also play a role in IDA. In this review, we evaluate and discuss the main mechanisms of IDA in CD and the possible causes of its persistence after adopting a GFD, as well as their therapeutic implications.

The Role of Gluten-Free Diet in Rebalancing Micronutrient Deficiencies in Children With Celiac Disease

Introduction: Celiac disease (CD) is one of the most common reasons for malnutrition. This study aimed to determine the status of the micronutrients, including vitamins and minerals in children with CD. Methods: The participants of this study included children <18 years old newly diagnosed with CD from January 2016 to December 2017 in the Clinic of Gastrointestinal and Digestive Diseases affiliated with Shiraz University of Medical Sciences. The diagnosis of CD was based on serological and pathologic findings. Finally, the data was analyzed using SPSS 22. Results: In the present study, 78 children with CD were evaluated, including 30 (38.5%) males and 48 (61.5%) females. The levels of hemoglobin and iron significantly improved after 6 months of treatment (P=0.001). In the present study, the level of calcium was below the normal range in 5 (6.4%) patients at diagnosis. However, its level was within a normal range in all patients 6 months after the treatment. Based on the results, the level of phosphorus was low in 24 (30.7%) and 5 (6.4%) patients before and after the treatment, respectively (P=0.001). Further, the vitamin D level was below a normal range in 66 (84.6%) and 15 (19.2%) patients at diagnosis and 6 months after the treatment, respectively (P=0.001). On the other hand, the mean level of folic acid increased from 16.5 at diagnosis to 22.39 after 6 months of treatment (P=0.001). Finally, the mean level of zinc also increased from 73.3 at diagnosis to 81.6 after 6 months of treatment (P=0.001). Conclusion: In general, the levels of iron, folate, vitamin D, and zinc reduced in patients with CD. In most patients, these deficiencies improved by receiving a gluten-free diet (GFD). Monitoring patients with CD is recommended for the diagnosis of micronutrient deficiencies.

Narrative Review: Nutrient Deficiencies in Adults and Children with Treated and Untreated Celiac Disease

Nutrient deficiencies are well recognized as secondary consequences of celiac disease (CD) and closely related to the clinical presentation of affected patients. Despite their clinical significance, consensus is lacking on the pattern and frequency of nutrient deficiencies in CD, the usefulness of their assessment at the time of diagnosis and during follow-up. This review aims to provide an overview of nutrient deficiencies among pediatric and adult CD patients at diagnosis and on a gluten-free diet (GFD), and their potential causes in CD. Secondly, we review their impact on CD management strategies including the potential of nutrient supplementation. A search of Medline, Pubmed and Embase until January 2019 was performed. Despite a high variability between the reported deficiencies, we noted that nutrient deficiencies occur frequently in children and adults with CD at diagnosis and during treatment with a GFD. Both inadequate dietary intake and/or diminished uptake due to intestinal dysfunction contribute to nutrient deficiencies. Most deficiencies can be restored with (long-term) treatment with a GFD and/or supplementation. However, some of them persist while others may become even more prominent during GFD. Our results indicate a lack of comprehensive evidence on the clinical efficacy of nutrient supplementation in CD management highlighting the need for further studies.

Hypoalbuminemia and generalized edema as an atypical presentation of celiac disease

The clinical presentation of celiac disease has evolved significantly over the last few decades. Previously defined as a malabsorption syndrome in pediatric patients, now it is considered an autoimmune disorder with diverse systemic manifestations among all age groups. We report a case of 56-year-old male presented with pedal edema and gradually progressive abdomen distention for the last 3 months. Serological evaluation and duodenal biopsy reports were suggestive of celiac disease. The patient was advised gluten-free diet, after 12 weeks, the patient became asymptomatic with the resolution of ascites and peripheral edema. According to the literature, there are few reports of protein-losing enteropathy as an initial presentation of celiac disease. The possibility of celiac disease should be considered even in the setting of atypical symptoms.

Multifactorial Etiology of Anemia in Celiac Disease and Effect of Gluten-Free Diet: A Comprehensive Review

Celiac disease (CD) is a multisystemic disorder with different clinical expressions, from malabsorption with diarrhea, anemia, and nutritional compromise to extraintestinal manifestations. Anemia might be the only clinical expression of the disease, and iron deficiency anemia is considered one of the most frequent extraintestinal clinical manifestations of CD. Therefore, CD should be suspected in the presence of anemia without a known etiology. Assessment of tissue anti-transglutaminase and anti-endomysial antibodies are indicated in these cases and, if positive, digestive endoscopy and intestinal biopsy should be performed. Anemia in CD has a multifactorial pathogenesis and, although it is frequently a consequence of iron deficiency, it can be caused by deficiencies of folate or vitamin B₁₂, or by blood loss or by its association with inflammatory bowel disease (IBD) or other associated diseases. The association between CD and IBD should be considered during anemia treatment in patients with IBD, because the similarity of symptoms could delay the diagnosis. Vitamin B₁₂ deficiency is common in CD and may be responsible for anemia and peripheral myeloneuropathy. Folate deficiency is a well-known cause of anemia in adults, but there is little information in children with CD; it is still unknown if anemia is a symptom of the most typical CD in adult patients either by predisposition due to the fact of age or because biochemical and clinical manifestations take longer to appear.

Beneficial effects of gluten free diet on IgA tissue transglutaminase levels and various growth parameters in celiac disease patients

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.

Comparison of Endoscopic and Histological Findings between Typical and Atypical Celiac Disease in Children

PURPOSE

Celiac disease is a common non-communicable disease with varied presentations. Purpose of this study was to find the duodeno-endoscopic features in celiac disease and to compare duodeno-endoscopic and histological findings between typical and atypical celiac disease in children.

METHODS

Hospital based observational study was conducted at Sir Padampat Mother and Child Health Institute, Jaipur from June 2015 to May 2016. Patients were selected and divided in two groups- typical and atypical celiac disease based upon the presenting symptoms. Upper gastrointestinal endoscopy and duodenal biopsy was performed for serology positive patients. Results were analysed using appropriate statistical test of significance.

RESULTS

Out of 101 enrolled patients, 47.5% were male. Age ranged from 1 to 18 years. Study showed that 54.5% were typical and 45.5% were atypical. Patients presenting with atypical symptoms were predominantly of older age group. On endoscopy, scalloping, mosaic pattern, reduced fold height and absent fold height; and in histology, advanced Marsh stage were significantly higher in the typical group.

CONCLUSION

Awareness of atypical presentations as well as duodeno-endoscopic features may have considerable practical importance for the diagnosis of celiac disease in children. Scalloping, mosaic pattern, reduced fold height and nodularity are main endoscopic markers of celiac disease in children. Endoscopic markers of duodenal mucosa may be important in early diagnosis of celiac disease, in children subjected to endoscopy for atypical presentations or indication other than suspected celiac disease.

Spectrum of Celiac disease in Paediatric population: Experience of Tertiary Care Center from Pakistan

Objective:

To determine clinical features and relevant laboratory investigations of patient with celiac disease (CD) and comparing classical celiac disease (CCD) with Non-diarrheal celiac disease (NDCD).

Methods:

This is a five years retrospective study conducted at The Aga Khan University Hospital Karachi, Pakistan from January 2010 to December 2015, enrolling children from one year to 15 years of either gender diagnosed as celiac disease in accordance with revised ESPGHAN criteria. Biopsy samples with grade 2 or more on Modified Marsh Classification were considered as consistent with celiac disease. Celiac patients were categorized into Classical celiac disease (with Chronic Diarrhea) and non-diarrheal celiac disease (Atypical celiac) and their clinical features and relevant laboratory investigations were documented.

Results:

Total 66 patients were selected with celiac disease according to inclusion criteria, 39 (59.09%) patients were labeled as CCD and 27 (40.91%) patients were labeled as NDCD. Marsh grading 3a and above were more marked in CCD as compared to NDCD. Mean titer for Tissue transglutaminase antibodies (TTG) were higher in CCD group in comparison to NDCD group. In CCD, the most common clinical presentations were abdominal distension whereas in NDCD, the most remarkable features were recurrent abdominal pain (62.9%). Frequency of failure to thrive is significantly high in CCD (82.05%) but patients merely with short stature were more common in NDCD (33.3%). Refractory anemia was present in 66.6% patients in NDCD group and 41.1% patients in CCD group. 74.3% patients in CCD group were vitamin D deficient whereas 85% patient had vitamin D deficiency in NDCD group (p= 0.03).

Conclusion:

NDCD is not uncommon in our population. Recurrent abdominal pain, failure to thrive or patients only with short stature and refractory anemia are prominent features in NCDC group whereas abdominal distension, failure to thrive and recurrent abdominal pain were noticeable features in CCD. High grade histopathology and raised antibodies titer is hallmark of CCD. Vitamin D deficiency is almost equally present in both groups.

Micronutrient Deficiencies in Pediatric Celiac Disease

Celiac disease (CD) is an autoimmune enteropathy that occurs in response to gluten ingestion in predisposed individuals. The autoimmune response results in villous atrophy in the small intestine, the primary site of nutrient absorption. Consequently, micronutrient deficiencies may occur in undiagnosed CD. Deficiencies in calcium, vitamin D, iron, folate, vitamin B12, and zinc have all been demonstrated in children with CD. Complications as a result of these nutrient deficiencies may affect a child’s growth, development, and overall well-being. The gluten-free diet (GFD) is the only known treatment for CD. Compliance with the diet is vital in correcting and preventing future micronutrient deficiencies. The purpose of this article is to give a background on CD and to present research that has shown micronutrient deficiencies in the pediatric population. The article will also focus on the crucial role of the health care team in both the recognition and management of pediatric patients with CD.

Child with multiple fractures: a rare presentation of a common disease

Bone fractures are not uncommon in paediatric age. However, when recurrent, an underlying clinical condition must not be excluded. We describe the case of a boy aged 7 years, referred for investigation of recurrent bone fractures. Personal and family histories were unremarkable. Physical examination was normal. Almost all primary bone disorders were excluded. Additional laboratory investigations ruled out the majority of secondary causes of bone fragility. Coeliac disease (CD) serologies, however, were positive, and duodenal biopsies confirmed this diagnosis (Marsh III B). On a gluten-free diet, he suffered no more fractures and the bone mineral density improved. CD was also confirmed in his asymptomatic older brother. It is essential to diagnose CD as early as possible in order to minimise the compromise in bone health and prevent other complications of the disease. First-degree relatives should always be screened for the disease, even asymptomatic ones.

Yield of coeliac screening in abdominal pain-associated functional gastrointestinal system disorders

AIM

Chronic abdominal pain (CAP) in childhood is common and in the majority functional. While CAP is one of the complaints of coeliac disease (CD), whether CAP as a sole complaint is indicative of CD is unclear. Our aim was to evaluate the relationship between CAP and CD.

METHODS

The study was conducted on 1047 children (61.1% female, mean age 9.6 ± 4.1 years) with CAP. Patients were evaluated according to the Rome III criteria. Patients with alarm symptoms and conditions known to be associated with CD were excluded. Patients were screened for CD using a rapid tissue transglutaminase (tTG) test; positive cases were tested by tTG ELISA, and duodenal biopsies were obtained if tTG was above the normal limit.

RESULTS

Functional dyspepsia (FD), irritable bowel syndrome (IBS) and functional abdominal pain (FAP) were diagnosed in 384 (36.7%), 274 (26.2%) and 389 (37.2%) patients, respectively. In 13 patients, the tTG rapid test was positive; 10 were also positive for tTG by ELISA and histopathological evaluations diagnosed CD in all 10 patients. The overall prevalence of CD was 0.95% (2.2%, 0.5% and 0.5% in patients with IBS, FD and FAP, respectively). The prevalence of CD in patients with IBS was higher than expected but with borderline statistical significance (P = 0.053).

CONCLUSIONS

CD is found as common in children with FD and FAP as in the general population. CD was more commonly diagnosed in IBS patients with borderline statistical significance. We suggest that particular attention be paid to children with IBS.

Theoretical pharmacokinetic drug alterations in pediatric celiac disease

INTRODUCTION

The incidence of pediatric celiac disease has risen and many of these children will receive medications at some time in their life. However, the absorption of drugs in pediatric patients with celiac disease has never been studied. The few studies that do exist have only been performed in adults and indicate that drug concentrations can be altered for some drugs. It is also noteworthy that few researchers have conducted studies to determine if the distribution, metabolism, and excretion of drugs are altered in celiac disease.

AREAS COVERED

The pharmacokinetics of drugs greatly differ between children and adults. Combined with the pathophysiological changes known to occur with celiac disease, there is compelling evidence to support that drug exposure in pediatric celiac disease may be altered. Relevant characteristics of celiac disease that may affect drug disposition include intestinal atrophy, hypoalbuminemia, reduced CYP3A enzymes, and thyroid dysfunction.

EXPERT OPINION

The safety and efficacy of drug dosing in children with celiac disease can be enhanced with additional pharmacokinetic studies of commonly prescribed drugs in this population. Ideally, these studies should include drugs that have high bioavailability, are highly protein bound, undergo extensive CYP3A enzyme metabolism, and/or have a narrow therapeutic range.

Changing face and clinical features of celiac disease in children

BACKGROUND

The aim of this study was to analyze and compare the epidemiological and presenting features, clinical patterns, and complications of celiac disease (CD) in children.

METHODS

The clinical charts of children with CD were retrospectively analyzed. Data for children who presented during the first time period (January 2005-October 2008; group 1) were compared to those of children who presented during the second time period (November 2008-April 2012; group 2).

RESULTS

Group 1 and 2 consisted of 96 and 95 children, respectively. There were no differences in gender distribution, weight, or height z-scores between the two groups. Mean age at the time of diagnosis in group 2 (9.3 ± 4.5 years) was significantly higher than in group 1 (6.9 ± 3.9 years; P < 0.001). Non-classical presentation was more frequent in group 2 (P = 0.01). Associated disorders were observed in 49 children (25.7%) overall. There were significantly more children with type 1 diabetes mellitus in group 2 (P = 0.030). In all, 11 patients (5.8%) were overweight (either obese or at risk of obesity) at presentation. Isolated short stature was the presenting feature in 15 children (7.9%) overall, but was more frequently observed in group 2 (P = 0.003). In total, 15 patients (7.9%) presented with refractory iron deficiency anemia; the frequency was similar in both groups. Dual-energy X-ray absorptiometry was performed in 102 patients, and 82 (80.4%) had metabolic bone disease (MBD).

CONCLUSION

The mode of presentation and clinical features of CD in childhood continue to change. Of note, a substantial percentage of patients were overweight at presentation. MBD is a frequent complication, necessitating routine evaluation.

Zinc and gastrointestinal disease

This review is a current summary of the role that both zinc deficiency and zinc supplementation can play in the etiology and therapy of a wide range of gastrointestinal diseases. The recent literature describing zinc action on gastrointestinal epithelial tight junctions and epithelial barrier function is described. Zinc enhancement of gastrointestinal epithelial barrier function may figure prominently in its potential therapeutic action in several gastrointestinal diseases.

Appropriate nutrient supplementation in celiac disease

Reduced levels of iron, folate, vitamin B12, vitamin D, zinc, and magnesium are common in untreated celiac disease (CD) patients probably due to loss of brush border proteins and enzymes needed for the absorption of these nutrients. In the majority of patients, removal of gluten from the diet leads to histological recovery and normalization of iron, vitamin, and mineral levels. Iron deficiency anemia is the most common extra-intestinal sign of CD and usually resolves with adherence to a gluten-free diet. However, deficiencies of both folate and vitamin B12 may persist in some patients on a gluten-free diet, thus requiring vitamin supplementation to improve subjective health status. Similarly, exclusion of gluten from the diet does not always normalize bone mineral density; in these cases, supplementation of vitamin D and calcium is recommended. Resolution of mucosal inflammation may not be sufficient to abrogate magnesium deficiency. Since gluten-free cereal products have a lower magnesium content as compared with gluten-containing counterparts, a magnesium-enriched diet should be encouraged in CD patients. In this article we discuss the frequency and clinical relevance of nutrient deficiency in CD and whether and when nutrient supplementation is needed.

Celiac disease presentation in a tertiary referral centre in India: current scenario

BACKGROUND

Nondiarrheal celiac disease (NDCD) is being increasingly reported but data from India is limited.

AIM

We undertook this study to compare the clinical spectrum of NDCD with that of diarrheal/classical celiac disease (CCD).

METHOD

This facility-based retrospective observational study included consecutive patients diagnosed with celiac disease (CD) (as per modified ESPGHAN criteria) from October 2009 to August 2011.

RESULTS

A total of 381 patients were diagnosed with CD during the study period. NDCD was present in 192 (51.8 %). NDCD had higher mean age at presentation (5.8 ± 2.8 vs. 6.9 ± 2.9 years respectively; p = 0.003) and longer duration of symptoms prior to diagnosis (2.9 ± 1.7 years vs. 3.6 ± 2.2 years; p = 0.02) as compared to CCD. In the NDCD group, the most frequent gastrointestinal (GI) symptoms were recurrent abdominal pain [122 (63.5 %)] and abdominal distension [102 (53.1 %)] followed by constipation [48 (25 %)], vomiting [76 (39.6 %)] and recurrent oral ulcers [89 (46.4 %)]. Vomiting and constipation were more frequently seen in NDCD as compared to CCD (p < 0.001 in both). Commonly enumerated extraintestinal manifestations in NDCD included failure to thrive [109 (56.8 %)], isolated short stature [36 (18.8 %)], persistent anemia [83 (43.2 %)] and hepatomegaly/splenomegaly or both [56 (29.2 %)]. Associated comorbidities included autoimmune thyroiditis [11 (5.7 %)], type 1 diabetes mellitus [8 (4.2 %)], bronchial asthma [23 (11.9 %)], idiopathic pulmonary hemosiderosis [4 (2.1 %)], Down's syndrome [3 (1.6 %)], alopecia areata [6 (3.1 %)], polyarthritis [2 (1.0 %)], dermatitis herpetiformis [6 (3.1 %)] and chronic liver disease [6 (3.1 %)]. The number of patients with a Marsh score IIIb and above of duodenal biopsy was significantly more in the CCD group (p < 0.001).

CONCLUSIONS

NDCD is not uncommon in India. Long-term follow up is needed to evaluate the impact of the disease and of treatment in these children.

[Current indications of ileocolonoscopy in children in 2012]

Les indications de l’iléo-coloscopie chez l’enfant ont été définies en 2002 par le Groupe francophone d’hépatologie gastroentérologie et nutrition. Ces recommandations sont mises à jour sous l’éclairage des nouvelles données et avancées technologiques de la dernière décennie. L’iléo-coloscopie reste essentiellement indiquée devant les hémorragies digestives (méléna ou rectorragies, anémie) et les suspicions de maladie inflammatoire chronique intestinale (MICI). Elle est désormais indiquée pour contrôler l’évolution des MICI, notamment pour contrôler la cicatrisation muqueuse sous traitement et l’absence de récidive postopératoire. Les indications d’iléo-coloscopie itérative sont surtout représentées par les polyposes génétiques avec des recommandations validées pour la polypose adénomateuse familiale. Les contre-indications n’ont pas été modifiées.

The Value of Ensari's Proposal in Evaluating the Mucosal Pathology of Childhood Celiac Disease: Old Classification versus New Version

OBJECTIVE

Small intestinal biopsy remains the gold standard in diagnosing celiac disease (CD); however, the wide spectrum of histopathological states and differential diagnosis of CD is still a diagnostic problem for pathologists. Recently, Ensari reviewed the literature and proposed an update of the histopathological diagnosis and classification for CD.

MATERIALS AND METHODS

In this study, the histopathological materials of 54 children in whom CD was diagnosed at our hospital were reviewed to compare the previous Marsh and Modified Marsh-Oberhuber classifications with this new proposal.

RESULTS

In this study, we show that the Ensari classification is as accurate as the Marsh and Modified Marsh classifications in describing the consecutive states of mucosal damage seen in CD.

CONCLUSIONS

Ensari's classification is simple, practical and facilitative in diagnosing and subtyping of mucosal pathology of CD.

Screening for celiac disease in children with dental enamel defects

Background. Dental enamel defects (DEDs) are seen in celiac disease (CD). Aim was to detect frequency of CD among such patients. Methods. This study included 140 children with DED. They were tested for CD. Gluten-free diet (GFD) was instituted for CD patients. A cohort of 720, age and sex-matched, normal children represented a control group. Both groups were evaluated clinically. Serum calcium, phosphorus, alkaline phosphatase, serum IgA, and tissue transglutaminase (tTG) IgG and IgA types were measured. Results. CD was more diagnosed in patients with DEDs (17.86%) compared to controls (0.97%) (P < 0.0001). Majority of nonceliac patients showed grade 1 DED compared to grades 1, 2, and 3 DED in CD. Five children had DED of deciduous teeth and remaining in permanent ones. After 1 year on GFD, DED improved better in CD compared to nonceliac patients. Gastrointestinal symptoms did not vary between celiac and nonceliac DED patients. Lower serum calcium significantly predicted CD in this cohort. Conclusion. CD is more prevalent among children with DED than in the general population. These DEDs might be the only manifestation of CD; therefore, screening for CD is highly recommended among those patients especially in presence of underweight and hypocalcemia.

Clinical presentation of celiac disease among pediatric compared to adolescent and adult patients

BACKGROUND

Celiac disease (CD) is being increasingly recognized in adults though a majority of patients continue to be diagnosed in childhood.

AIM

To compare the clinical presentation and profile of newly diagnosed pediatric and adolescent/adult CD patients.

MATERIALS AND METHODS

Retrospective analysis of patients diagnosed with CD between year 1997 and 2007 in the pediatric group, and between year 2000 and 2007 in the adolescent/adult group was done for clinical presentation, endoscopic findings and duodenal histology.

RESULTS

A total of 434 children and 298 adults were studied. The mean age of diagnosis was 6.5 ± 2.5 years (1-11 years) in children and 29.3 ± 13.3 years (6-73 years) in adolescent/adults. The mean duration of symptoms before diagnosis was 3.5 ± 2.5 years in children and 4.9 ± 4.6 years in the latter. Diarrhea as the presenting symptom was seen in 74 % of children and 58.7 % of adolescent/adults. Anemia (on investigations) was seen in 84 % of children and 94 % of adolescent/adults.

CONCLUSIONS

Pediatric patients of CD present more often with typical features than adults. Atypical presentations are more common in adults and the latent period for diagnosis is also longer in adolescent/adults. There is a need for increasing awareness about CD, both among pediatricians and physicians caring for adult patients.

Burden of celiac disease in the Mediterranean area

AIM: To estimate the burden of undiagnosed celiac disease (CD) in the Mediterranean area in terms of morbidity, mortality and health cost.

METHODS: For statistics regarding the population of each country in the Mediterranean area, we accessed authoritative international sources (World Bank, World Health Organization and United Nations). The prevalence of CD was obtained for most countries from published reports. An overall prevalence rate of 1% cases/total population was finally estimated to represent the frequency of the disease in the area, since none of the available confidence intervals of the reported rates significantly excluded this rate. The distribution of symptoms and complications was obtained from reliable reports in the same cohort. A standardized mortality rate of 1.8 was obtained from recent reports. Crude health cost was estimated for the years between symptoms and diagnosis for adults and children, and was standardized for purchasing power parity to account for the different economic profiles amongst Mediterranean countries.

RESULTS: In the next 10 years, the Mediterranean area will have about half a billion inhabitants, of which 120 million will be children. The projected number of CD diagnoses in 2020 is 5 million cases (1 million celiac children), with a relative increase of 11% compared to 2010. Based on the 2010 rate, there will be about 550 000 symptomatic adults and about 240 000 sick children: 85% of the symptomatic patients will suffer from gastrointestinal complaints, 40% are likely to have anemia, 30% will likely have osteopenia, 20% of children will have short stature, and 10% will have abnormal liver enzymes. The estimated standardized medical costs for symptomatic celiac patients during the delay between symptom onset and diagnosis (mean 6 years for adults, 2 years for children) will be about €4 billion (€387 million for children) over the next 10 years. A delay in diagnosis is expected to increase mortality: about 600 000 celiac patients will die in the next 10 years, with an excess of 44.4% vs age- and sex-matched controls.

CONCLUSION: In the near future, the burden of CD will increase tremendously. Few Mediterranean countries are able to face this expanding epidemic alone.
