Abstract
Endocrine care of pediatric and adult patients continues to be plagued by health and health care disparities that are perpetuated by the basic structures of our health systems and research modalities, as well as policies that impact access to care and social determinants of health. This scientific statement expands the Society's 2012 statement by focusing on endocrine disease disparities in the pediatric population and sexual and gender minority populations. These include pediatric and adult lesbian, gay, bisexual, transgender, queer, intersex, and asexual (LGBTQIA) persons. The writing group focused on highly prevalent conditions-growth disorders, puberty, metabolic bone disease, type 1 (T1D) and type 2 (T2D) diabetes mellitus, prediabetes, and obesity. Several important findings emerged. Compared with females and non-White children, non-Hispanic White males are more likely to come to medical attention for short stature. Racially and ethnically diverse populations and males are underrepresented in studies of pubertal development and attainment of peak bone mass, with current norms based on European populations. Like adults, racial and ethnic minority youth suffer a higher burden of disease from obesity, T1D and T2D, and have less access to diabetes treatment technologies and bariatric surgery. LGBTQIA youth and adults also face discrimination and multiple barriers to endocrine care due to pathologizing sexual orientation and gender identity, lack of culturally competent care providers, and policies. Multilevel interventions to address these disparities are required. Inclusion of racial, ethnic, and LGBTQIA populations in longitudinal life course studies is needed to assess growth, puberty, and attainment of peak bone mass. Growth and development charts may need to be adapted to non-European populations. In addition, extension of these studies will be required to understand the clinical and physiologic consequences of interventions to address abnormal development in these populations. Health policies should be recrafted to remove barriers in care for children with obesity and/or diabetes and for LGBTQIA children and adults to facilitate comprehensive access to care, therapeutics, and technological advances. Public health interventions encompassing collection of accurate demographic and social needs data, including the intersection of social determinants of health with health outcomes, and enactment of population health level interventions will be essential tools.

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
The aim of the study was to investigate the coincidence of growth hormone deficiency (GHD) and celiac disease (CD) or inflammatory bowel disease (IBD) in patients referred for short stature, and to evaluate the baseline anthropometric parameters and the effectiveness of recombinant human growth hormone (rhGH) therapy in the first year in those patients (GHD+CD/IBD subgroup) in comparison to patients with GHD without CD or IBD (GHD-CD/IBD subgroup). Material and methods The study was retrospective and included 2196 short patients (height SDS [Standard Deviation Score] ≤ –1.2). 1454 patients had height SDS ≤ –2. Twenty-nine patients suffered from CD or IBD. GHD was confirmed in 419 patients with height SDS ≤ –2. The coexistence of GHD and CD or IBD was found in seven patients (GHD+CD/IBD subgroup). Results At baseline the GHD-CD/IBD subgroup did not differ significantly in chronological age, height SDS, height velocity (HV) before rhGH therapy, body weight SDS, and body mass index SDS from the GHD+CD/IBD subgroup. The improvement in height SDS within the first year of rhGH therapy was higher in the GHD+CD/IBD subgroup than in the GHD-CD/IBD subgroup and the difference was statistically significant (p<0.05). HV in the first year of rhGH therapy was also significantly higher in the GHD+CD/IBD subgroup than in the GHD-CD/IBD subgroup (p < 0.05). Conclusions In patients with chronic inflammatory disorders of the gastrointestinal tract, especially celiac disease, coexisting with GHD, rhGH therapy could be effective and should be administered together with therapy of primary gastrointestinal disease.

Abstract
Although the need for effective long-term follow-up for patients with celiac disease (CD) has been recognized by many expert groups, published practice guidelines have not provided a clear approach for the optimal management of these patients. In an attempt to provide a thoughtful and practical approach for managing these patients, a group of experts in pediatric CD performed a critical review of the available literature in 6 categories associated with CD to develop a set of best practices by using evidence-based data and expert opinion. The 6 categories included the following: bone health, hematologic issues, endocrine problems, liver disease, nutritional issues, and testing. Evidence was assessed by using standardized criteria for evaluating the quality of the data, grade of evidence, and strength of conclusions. Over 600 publications were reviewed, and 172 were chosen for inclusion. The thorough review of the results demonstrated that the quality of the data available was often insufficient to provide unequivocal best practices. However, using the available data and the clinical experience of the panel, a practical framework for the management of children with CD was created. These recommendations were developed by our expert panel and do not necessarily reflect the policy of the American Academy of Pediatrics. The potential usefulness of these best practices is underscored by the fact that consensus, measured by the outcome of anonymous voting, was reached by the panel for 24 of the 25 questions. We hope that these best practices may be useful to the pediatric gastroenterology and larger general pediatric communities.

Abstract
Although there are many commonalities between adult and pediatric celiac disease (CD), special considerations must be taken into account when working with children and adolescents. In this patient population, there are unique aspects of the epidemiology, pathogenesis, presentation, diagnosis, and management of CD. In terms of management, early and timely recognition of CD can maximize childhood and adolescent development and prevent complications. This requires insight into the unique presentations of CD in the pediatric population. Furthermore, health care providers must use proper screening methods and continue surveillance of at-risk individuals throughout childhood. Potential interventions for primary prevention of CD in children, although not completely understood, may offer some benefit. The goals of this article are to discuss in detail these special considerations when dealing with pediatric CD.

Abstract
Until a few years ago, celiac disease (CD) was thought to be a rare food intolerance that was confined to childhood and characterized by severe malabsorption and flat intestinal mucosa. Currently, CD is regarded as an autoimmune disorder that is common in the general population (affecting 1 in 100 individuals), with possible onset at any age and with many possible presentations. The identification of CD is challenging because it can begin not only with diarrhea and weight loss but also with atypical gastrointestinal (constipation and recurrent abdominal pain) and extra-intestinal symptoms (anemia, raised transaminases, osteoporosis, recurrent miscarriages, aphthous stomatitis and associated autoimmune disorders), or it could be completely symptomless. Over the last 20 years, the diagnostic accuracy of serology for CD has progressively increased with the development of highly reliable tests, such as the detection of IgA tissue transglutaminase and antiendomysial and IgG antideamidated gliadin peptide antibodies. The routine use of antibody markers has allowed researchers to discover a very high number of 'borderline' cases, characterized by positive serology and mild intestinal lesions or normal small intestine architecture, which can be classified as potential CD. Therefore, it is evident that the 'old celiac disease' with flat mucosa is only a part of the spectrum of CD. It is possible that serology could identify CD in its early stages, before the appearance of severe intestinal damage. In cases with a positive serology but with mild or absent intestinal lesions, the detection of HLA-DQ2 and HLA-DQ8 can help reinforce or exclude the diagnosis of gluten sensitivity.

Abstract
OBJECTIVE This prospective study was planned with the aim to determine the prevalence of anti-tissue transglutaminase in children and adolescents with severe short stature (<-3 SD) attending the Pediatric outpatient, inpatient and/or the Pediatric Gastroenterology clinic. METHODS All children in age group of 1-18 years having height less than -3 SD for their age and sex, were included. For each child age and sex matched healthy control (height more than -2 SD) was taken. The included subjects (study & control group) were subjected to anti tissue transglutaminase (tTG) (IgA) antibody assay estimation. RESULTS Of the 112 cases, 23 were tTG positive, giving a prevalence of 20.5% for seropositivity among cases of short stature while all the controls were seronegative for tTG. All the 23 had tTG values above 40 U/ml and 11 had values above 100 U/ml. On univariate analysis we found that the presence of chronic diarrhea (OR = 2.55, 95%CI - 1.08-5.98), bulky stools (OR = 3.03, 95%CI - 1.52-6.05), hemoglobin < 7 gm/dl (OR = 3.12, 95%CI - 1.55-6.29) and more severe short stature (<-4 SD) (OR = 0.41, 95%CI - 0.17-0.95) had significant association with the tTG positivity. On logistic regression analysis in all cases, hemoglobin < 7gm/dl (OR = 0.090, 95%CI = 0.024-0.342) and bulky stools (OR=0.212, 95%CI = 0.069-0.649) were significantly associated with tTG positivity. CONCLUSION More than one fifth of all severe short stature are seropositive for tTG and the chances of seropositivity increases if severe anemia and bulky stool are also associated.

Abstract
Celiac disease (CD) is a prevalent, genetically determined, autoimmune, chronic inflammatory state caused by intolerance to gluten that results mainly in gastrointestinal manifestations. One of the most common extra-intestinal manifestations of CD is short stature, and in some patients, short stature may be the presenting and only symptom of the disease, making the diagnosis of CD challenging. Impaired growth in children with CD results mainly from nutritional deficits, and withdrawal of gluten from the diet is frequently associated with a marked improvement of linear growth. In some patients, CD may be characterized by growth hormone (GH) resistance, as suggested by normal or elevated GH levels and low insulin-like growth factor-I (IGF-I) levels. Rarely, it has been shown that poor catch-up growth and/or IGF-I response to gluten-free diet may be due to the coexistence of celiac disease and GH deficiency. We present two children with coexisting CD and GH deficiency. One patient had MRI findings suggesting congenital isolated GH deficiency, and a possibility of developing multiple pituitary hormone deficiencies later in life.

Abstract
AIM: To determine the prevalence of celiac disease (CD) in children with idiopathic short stature (ISS) and the diagnostic value of immunoglobulin (Ig) A G antigliadin antibodies (AGA) and transglutaminase (TTG) antibodies for CD.
METHODS: A total of 104 children (49 male, 55 female) with ISS without a specific etiology were studied. Extensive endocrine investigations had shown no abnormalities in any subject. Anthropometric parameters and IgA AGA and IgA TTG antibodies were evaluated in this study group. These antibodies were measured by enzyme-linked immunosorbent assay. All patients were referred for an endoscopic intestinal biopsy. The biopsy samples were classified according to revised Marsh criteria (UEGW 2001).
RESULTS: We detected positive IgA TTG antibodies in 36 and IgA AGA in 35 of these patients. Thirty one IgA TTG antibody positive and 28 IgA AGA positive subjects showed histological abnormalities compatible with celiac disease (33.6%). Sensitivity, specificity, positive predictive value (PPV) and negative predictive value for IgA AGA were found to be 80%, 88.4%, 77.8% and 89.7%, respectively. Sensitivity, specificity and PPV for IgA TTG antibodies were 88.6%, 94.2% and 88.6%, respectively.
CONCLUSION: We conclude that the prevalence of celiac disease is high in patients with ISS and it is important to test all children with ISS for celiac disease by measuring serologic markers and performing an intestinal biopsy.

Abstract
OBJECTIVE The aim of the present study was to determine the prevalence of celiac disease in children with short stature. METHODS In all children with short stature (height more than 2 SD below the mean for age and sex) and normal physical examination, attending Motahary pediatric clinic in Shiraz, Iran, from 2003 till 2005, work-ups were made to find a cause for their short stature and of course their serum was assayed for IgG anti-tissue transglutaminase (TTG) antibody by ELISA test, as a marker for CD. RESULTS There were 26 girls and 46 boys with mean age of 9.8 years. Routine work-up showed microcytic hypochromic anemia in four children (5.6%) and giardiasis in five (6.9%). GH stimulation test revealed GH deficiency in five children (6.9%). Elevated IgG anti-TTG antibody level was detected in two children (2.8%). Duodenal biopsies of these children were in favor of celiac disease. CONCLUSION Although, the prevalence of CD in this study was not significantly different (P value = 0.14) from the prevalence rate in healthy blood donors in Iran, the findings emphasize the fact that CD must be considered in a child with short stature, especially if the height is more than 3 SD below the mean for sex and age, even in the absence of gastrointestinal symptoms. In conclusion, the measurement of anti-TTG antibody should be included in the diagnostic evaluation of children with short stature.

Abstract
INTRODUCTION Coeliac disease (CD) is usually associated with impaired growth in children. A gluten-free diet (GFD) induces a catch-up growth with the recovery of height in about 2 years. AIM AND DISCUSSION: The lack of the height improvement has been related to growth hormone (GH) secretion impairment. CD is an autoimmune disease often associated with other endocrine and non-endocrine autoimmune disease. The aim of this study was to evaluate antipituitary autoantibodies (APA) and antihypothalamus autoantibodies in CD children with poor clinical response to a GFD and growth hormone deficiency (GHD). We diagnosed CD on the basis of specific antibodies and endoscopic biopsies in 130 patients aged 1-15 years. Seven CD children, without catch-up growth after at least 12-months GFD, were tested for GH secretion and, in five out of seven patients, the diagnosis of GHD was made in the absence of metabolic and systemic diseases. RESULTS APA and antihypothalamus antibodies were detected by the indirect immunofluorescence method in the seven CD children without catch-up growth factor and in 25 CD children without growth impairment matched for sex and age, and in 58 healthy children as control groups. APA resulted positive at high titres in four out of five CD-GHD patients and were also positive at low titres (<1:8) in three of only CD children and in two out of 58 controls. Hypothalamic-pituitary magnetic resonance imaging (MRI) was normal in all patients except in one with cystic pineal. APA have been previously detected not only in adults with GHD, but also in idiopathic GHD children, suggesting the occurrence of an autoimmune hypophysitis in these patients. CONCLUSION In our study, the presence of APA in CD children without catch-up growth after GFD seems to be able to identify an autoimmune form of hypophysitis involving the somatotrophs cells.

Abstract
OBJECTIVES To assess the occurrence of growth hormone deficiency (GHD) in patients with celiac disease (CD) referred for short stature. DESIGN A retrospective, multi-center study. A total of 7066 children with short stature were referred to a number of centers for second-line evaluation over a 5-year period. All patients were screened for CD by antiendomysial antibodies (EMA) and antitissue transglutaminase IgA. Those with positive sera underwent intestinal biopsy. The EMA-negative patients and the EMA-positive ones who did not grow after 1 year of gluten-free diet underwent endocrinological investigation. RESULTS Among the 7066 short children (age 2-14 years) evaluated, 650 (9.2%) had GHD and 44 (0.63%) had CD. An association of both CD and GHD was found in 16 short children (0.23%); these children did not grow after 1 year of gluten-free diet and therefore GH treatment was started. CONCLUSIONS GH secretion should be evaluated in celiac patients showing no catch-up growth after an appropriate period on a gluten-free diet in spite of reversion to seronegativity for EMA.

Abstract
This prospective study was carried out to evaluate the clinical and anthropometric profile of 71 children confirmed to have celiac disease on the basis of clinical features, duodenal biopsy and unequivocal improvement on gluten-free diet. Serological tests were performed in 35 cases. The patients were divided into three age groups <5 years, 5-10 years, and >10 years as per the age of presentation to the hospital. Mean age was 8.7 years with a slight female preponderance. Diarrhea was the commonest presentation in group I and failure to thrive in group III. All patients in group III, had weight for age (w/a) <3rd percentile and majority (83 per cent) had short stature, with delayed puberty in all. All children had significant improvement in symptoms and growth on gluten restriction. None of the patients had been suspected to have celiac disease before, which signifies that in spite of increasing incidence of celiac disease, this disease is grossly under-diagnosed in North India where wheat is the staple diet. It is essential to make an early diagnosis of celiac disease in children to prevent growth delay.

Abstract
OBJECTIVE To evaluate the effect of a gluten-free diet on growth and adult height, when available, in coeliac children without gastrointestinal symptoms. PATIENTS AND METHODS Sixty-one coeliac children without gastro-intestinal symptoms were included in the study. The age at diagnosis was 9.50 +/- 3.3 years. Thirty-eight had short stature at diagnosis (< 10th percentile) and 23 had normal stature. Thirty-seven reached adult height. RESULTS After beginning the diet an increase in growth velocity was seen in 30 patients (responders) (20 with initial short stature), while in 31 patients (18 with short stature) there was no catch-up growth (non-responders). Bone age at diagnosis was significantly more delayed in the responders than in the non-responders. Target height was significantly higher in children with normal stature at diagnosis than those with short stature. Growth hormone (GH) deficiency was found and confirmed after 6-12 months of diet in 12 of the 38 patients (32%) with short stature. In the group of the 30 'short' patients who attained final height, target height was attained or improved in 12 patients (40%): in eight of the 16 (50%) responders and in four of the 14 (29%) non-responders; in eight (all responders) out of 22 (36%) without GH deficiency, and in four out of eight (50%) patients with GH deficiency treated with GH (all non-responders). CONCLUSIONS In children in whom coeliac disease is diagnosed because of short stature, a gluten-free diet will be successful if at diagnosis there is a delay of bone age and in the first year of diet there is an evident catch-up growth. When this does not occur, i.e. in half of the patients (18 out of 38), it may be because of an associated and transient GH deficiency. In these patients a period of GH replacement therapy as well as a gluten-free diet may improve their final height.

Abstract
OBJECTIVE To assess the occurrence of growth hormone deficiency (GHD) in patients with coeliac disease (CD). STUDY DESIGN A total of 1066 children diagnosed elsewhere with short stature were referred to our centre for second-line evaluation in a 6-year period. All patients were screened for CD by antiendomysial antibodies (EMA) and those with positive sera underwent intestinal biopsy. RESULTS Among the 1066 short children, 210 (19.7%) had GHD and 12 (1.12%; chronological age from 3.6 to 12.3 years, bone age from 1.5 to 10.5 years, SDS height from -3.05 to -0.48), having positive EMA, showed histologically confirmed CD. Nine of these latter 12 CD children had a beneficial effect on growth rate after the first year of gluten-free diet, while the remaining three showed no catch-up growth. A careful endocrinological investigation in these three CD boys showed an isolated GHD in two cases and a multiple GHD in one case. The congenital origin of GHD is supported by the congenital abnormalities documented by magnetic resonance imaging. GH therapy associated with gluten-free diet led to an increased growth rate. CONCLUSION GH secretion should be evaluated in coeliac patients showing no catch-up growth after a period on a gluten-free diet in spite of reversion to seronegativity for EMA. In the case of GHD and CD, replacement GH therapy should be started during a gluten-free diet.

Abstract
Coeliac disease (CD) is a permanent intolerance to gluten that results in damage of the small intestinal mucosa, and it is one of the common causes of chronic malabsorption in children. It is well known that patients with CD are at great risk of malignant complications, but in patients with CD many other disorders have been recognized. Autoimmunity diseases, such as type 1 diabetes mellitus, thyroid diseases, and autoimmune polyglandular syndromes are known to be associated with CD, and they seem to be related to gluten exposure. Growth, bone metabolism, and fertility can be affected in patients with CD, especially if they are not on a gluten-free diet. We review the literature on endocrine aspects of CD, because patients with CD are at great risk of developing endocrine disorders.

Abstract
The prevalence of celiac disease (CD) in Sweden is about 4 cases per 1,000 people. Screening for CD with serological tests indicates similar high prevalences in many other countries. Between 1 November 1992 and 30 April 1995, 133 children (9 months to 16.7 years of age) with suspected CD were studied. The predictive value (PV) of immunoglobulin A antigliadin antibodies (IgA-AGA) in the serum as assayed with two new commercial automated immunoassays--the Pharmacia CAP System Gliadin IgA FEIA (CAP) and the UNICAP-100 (UNICAP)--and with three "in-house" methods was evaluated using assessment of the small intestinal mucosa morphology as the "gold standard." All serum samples were analyzed for total serum IgA. At presentation the diagnostic sensitivities and specificities of the different tests varied from 0.72 to 0.88 and 0.67 to 0.87, respectively. All methods showed a higher sensitivity for CD in younger children. The area under each assay's receiver operating characteristic curve was calculated and varied between 0.82 and 0.89. The positive and negative PVs for the CAP and UNICAP, which were assays with a high sensitivity and a high specificity, respectively, were estimated. In the clinically selected population (prevalence of CD, 1 in 3) the positive PV was about 55%, and in the general population (prevalence, 1 in 250) it was about 1%. The negative PVs for both CAP and UNICAP were close to 100%; thus, when the AGA test was negative, the risk for CD was small. Interestingly, five children had serum IgA levels below the detection limit (<0.07 g/liter) when on a gluten-free diet, whereas they had normal levels at the time of the first biopsy. In conclusion, the automated immunoassays--based on ImmunoCAP technology--for analysis of IgA-AGA had a reliability comparable to that of the in-house methods.

Abstract
BACKGROUND Endomysium antibodies (EmAb) are strongly associated with untreated celiac disease and are suggested to be diagnostic. The aim of the present study was to assess the value of anti-EmAb for celiac disease screening in children with short stature. METHODS In 84 children with height less than the third percentile for age, preliminary work-ups were made to find a cause for their short stature and then their serum was assayed for anti-EmAb by indirect immunofluorescence tests using monkey esophagus. RESULTS Seven children were strongly positive for EmAb and all had positive histologic findings for celiac disease. CONCLUSIONS Our results show that there is an association with occult celiac disease and idiopathic short stature and that the serum anti-EmAb test is useful in identifying such cases.

Abstract
BACKGROUND It is generally accepted that celiac disease (CD) must always be considered when dealing with growth failure in children. Therefore, it is important to develop screening tests for detecting patients that need an intestinal biopsy. The aim of the present study was to investigate the value of plasma zinc levels for the diagnosis of monosymptomatic CD in short-statured children. METHODS Fourty-nine children with a short stature and 34 healthy controls were investigated. Plasma zinc levels were assayed by atomic absorption spectrophotometry in short-statured children and controls. All patients with short stature underwent endoscopic small intestinal biopsy. RESULTS Duodenal mucosal histopathology was normal in 25 children. Low plasma zinc values were observed in 54.2% of patients with CD, 32.0% of patients with idiopathic short stature and 14.8% of controls. The mean values of plasma zinc levels were not significantly different among the three groups. Sensitivity, specificity and the positive and negative predictive values for plasma zinc were 45.8, 76.0, 64.7 and 59.4%, respectively. CONCLUSIONS These results indicate that zinc deficiency is an important problem in CD children with short stature; however, plasma zinc levels are not useful as a screening test for selecting patients for jejunal biopsy.

Abstract
BACKGROUND Clinical experience leads us to believe there may be patients with celiac disease who have not yet been treated, with a normal physical growth. METHODS To evaluate height velocity of patients with confirmed celiac disease before their diagnosis and treatment, anthropometric measurements taken by the general pediatricians in charge of the primary care of the patients before they were sent to the authors' hospital were studied. Forty-two growth periods (available velocities) were measured at varying intervals (ranging from 6 to 27 months) in 23 patients aged 0.1 to 10.66 years were analyzed. RESULTS All patients studied during the first semester of life (n = 5) showed normal growth velocity, and 6 of 10 patients showed normal growth velocity during the second semester of life. Ten of 12 patients between the ages of 1.0 and 1.99 years of age showed normal height velocity, and 7 of 9 patients aged 2.0 to 10.66 years showed normal height velocity. Normal height velocities were found not only during the first year of life, but also in children aged 1 to 8 years. CONCLUSIONS Results should alert pediatricians and those in gastroenterology and growth clinics. In the latter case, norms for studying children who have short stature but are growing at a normal rate should not be a condition for excluding a child from screening for celiac disease.

Abstract
Coeliac disease has been reported to occur in 2-5 per cent of insulin-dependent diabetic patients (IDDM). Suitable non-invasive screening tests would allow identification of these patients. The aim of this study was to determine the value of the red cell distribution width (RDW) in detecting unrecognised coeliac disease in insulin-dependent diabetic patients (IDDM). All patients (n = 208) attending the Diabetic out-patient clinics at 2 adjacent centres who had a full blood picture and RDW carried out in the past 18 months were included. IDDM patients with an elevated RDW were identified and their charts were reviewed to determine if they had symptoms or laboratory abnormalities compatible with coeliac disease. They were invited to attend for serological screening. Ninety-five of 208 patients had an elevated RDW of whom 66 had non-insulin dependent diabetes mellitus and 29 had IDDM. Two of the 29 IDDM patients had died in the interim period. Six of the remaining 27 IDDM patients had previously been tested for serological markers associated with coeliac disease, of whom 1 had a positive antigliadin antibody titre (IgA-AGA 199 EU) and normal duodenal biopsy. Eighteen of the remaining 21 patients with IDDM consented to serological testing of whom only 1 had a positive titre of antiendomysial antibody (IgA-EMA) and villous atrophy. Although the RDW is known from previous studies to be a sensitive predictor for coeliac disease, this study has demonstrated its poor specificity in predicting IDDM patients who may have coeliac disease. The RDW is not recommended as a screening test for coeliac disease in patients with IDDM.

Abstract
Coeliac disease and inflammatory bowel disease (IBD) individually are not uncommon in children, but the occurrence of both conditions together is rare. The combined presentation of coeliac disease and IBD in a girl of 7 years is presented with a review of the related literature. The occurrence of coeliac disease with IBD should be considered at the time of diagnosis and at relapse, or where there is difficulty maintaining remission in established IBD. Screening with serum antibody tests may be helpful.

Abstract
OBJECTIVE The demographic, clinical, and epidemiological features of subclinical/silent celiac disease in Italy were analyzed in a multicenter study carried out with the participation of 42 centers, in the years between 1990 and 1994. METHODS One thousand twenty-six subclinical/silent patients (644 children and 382 adults, 702 women and 324 men) were considered eligible for the study. RESULTS The prevalence of the subclinical/silent form increased significantly during the study both in adults (p < 0.001) and in children (p < 0.005), but its prevalence was always lower (p < 0.001) in children than in adults. This increase appears more likely due to a greater diagnostic awareness and to a better use of screening than to a higher number of subclinical/silent cases. Whereas in 1990 a significantly higher proportion (p < 0.001) of subclinical/silent celiac patients was diagnosed in Northern Italy rather than in Southern-Insular Italy, both in adults (46.7% vs 17.2%) and in children (22.0% vs 9.0%), in 1994 such a difference was no longer conspicuous. Both in children and in adults, iron-deficiency anemia appeared to be the most frequent extraintestinal symptom, followed by short stature in children and cutaneous lesions of dermatitis herpetiformis in adults. In 25.9% of the cases another disease was present, with a significantly higher frequency (p < 0.05) in adults (30.1%) than in children (20.7%). Diabetes and atopy appeared to be the most frequently associated conditions both in children and in adults. CONCLUSIONS This study has provided an analysis of the largest series of subclinical/silent celiac disease reported to date. In Italy, this form is most frequently recognized in adults, and prospective studies will clarify whether the lower frequency observed in children is a real or apparent phenomenon.

Abstract
BACKGROUND It is generally accepted that celiac disease (CD) must always be taken into consideration when dealing with children manifesting growth failure. It is, therefore, important to have laboratory tests capable of detecting patients who should undergo intestinal biopsy. In this study, we have prospectively evaluated clinical characteristics, gliadin antibody measurements and duodenal biopsies in 47 children with short stature and without gastrointestinal symptoms, in order to determine the incidence of CD and the diagnostic value of immunoglobulin (Ig)A and IgG antigliadin antibodies (AGA) for CD. METHODS Anthropometric parameters and IgA- and IgG AGA were evaluated in 47 children with short stature. Antigliadin antibodies were measured by enzyme-linked immunosorbent assay (Euroimmun kit). Endoscopic intestinal biopsies were taken from all children. RESULTS On the basis of intestinal biopsy, 26 (55.3%) patients were found to be probable CD. Sensitivity, specificity, positive predictive (PPV) and negative predictive value (NPV) for IgA AGA was found to be 23, 90, 75 and 48%, respectively. Sensitivity, specificity and PPV for IgG AGA was 100, 0 and 55%, respectively. The NPV for IgG AGA was not determined. CONCLUSIONS The results of our study demonstrated that because of their incomplete sensitivity, specificity, PPV and NPV, intestinal biopsy can not be replaced by these tests.

Abstract
BACKGROUND Hypertransaminasaemia of unknown, cryptogenic, origin occasionally has been found to be the only sign of coeliac disease. Raised concentrations of transaminases, or aminotransferases, have been retrospectively observed in about a half of patients with coeliac disease who are on a gluten-containing diet. We aimed to establish the overall prevalence of coeliac disease among patients with cryptogenic hypertransaminasaemia. METHODS Of the 600 consecutive patients referred to our outpatient clinic for liver disease due to raised serum transaminases from September, 1995, to June, 1997, 55 were classified as having cryptogenic hypertransaminasaemia after the exclusion of every known cause of liver disease. These patients were tested by indirect immunofluorescence for IgA to endomysium and for IgA and IgG to gliadin. FINDINGS Five patients were positive for both IgA to endomysium and IgG to gliadin, whereas IgA to gliadin was only found in four patients. IgG to gliadin was also present in another patient who was not positive for antibodies to endomysium. The six antibody-positive patients had duodenal biopsy that showed a subtotal villous atrophy consistent with coeliac disease in the five patients with antibodies to endomysium. The patient with only IgG to gliadin had a normal small-intestine mucosa. None of the five patients with coeliac disease had gastrointestinal symptoms. Liver biopsy samples were taken from three of the five patients with flat mucosa and showed a histological picture of nonspecific reactive hepatitis. Transaminase concentrations reverted to normal within 6 months in four patients with coeliac disease who followed a strict gluten-free diet. INTERPRETATION Our results show that about 9% of patients with cryptogenic hypertransaminasaemia are affected by symptom-free coeliac disease. Gluten-sensitive enteropathy and antibody screening for coeliac disease by means of antibodies to endomysium and gliadin should be considered in these patients.

Abstract
Coeliac disease is the life-long intolerance to dietary gluten, usually characterized by severe damage to the small-intestinal mucosa. The widespread use of sensitive diagnostic tools, such as the serum anti-gliadin and the anti-endomysial antibodies, has shown not only that coeliac disease is one of the commonest disorders in Western countries but also that this condition is characterized by a higher degree of clinical variability than previously thought (typical, atypical and silent forms). The existence of a latent-potential coeliac disease and even a gluten-sensitive disease with immunological activation of an otherwise normal small-intestinal mucosa has recently been postulated. An increased prevalence of coeliac disease in a number of other disorders has also been reported in both children and adults. The reasons for such a wide clinical heterogeneity are still poorly understood but are likely to depend on both genetic and environmental factors. Further investigations are required to evaluate the impact of undiagnosed, clinically milder forms of coeliac disease on the well-being of the population.

Abstract
BACKGROUND The possibility of assaying antiendomysial antibodies (EmA) on the human umbilical cord instead of monkey esophagus has recently been suggested. We therefore evaluated in patients with celiac disease (CD) the sensitivity and specificity of EmA and of antigliadin antibodies (AGA) for both umbilical cord and monkey esophagus. METHODS We studied 36 patients with CD and atrophy of the intestinal mucosa (median age, 1.4 years), 14 patients with CD on gluten-free diet for 8-12 months (median age, 3.0 years), 36 controls without gastrointestinal disease (median age, 4.0 years), and 72 patients with cow's milk protein enteropathy (CMPE) (median age, 1.2 years). AGA and EmA on monkey esophagus were assayed with commercially available kits; the slides with umbilical cord were prepared in our laboratory. RESULTS There was a perfect concordance between EmA results evaluated on umbilical cord and those on monkey esophagus; there was a doubtful result in only one case on human umbilical cord, which was positive with low titer on monkey esophagus. EmA specificity was 100%; the specificity of AGA IgG varied between 72% and 94% and of AGA IgA between 90% and 100% depending on whether controls without gastrointestinal disorders or patients with CMPE were considered. EmA sensitivity was 97%, AGA IgG was 89%, and AGA IgA 72% sensitive. The only false negative for EmA was positive for AGA IgG and AGA IgA. CONCLUSIONS Using human umbilical cord as a substrate for EmA may provide the same sensitivity and specificity as offered by the test using monkey esophagus substrate, thus reducing costs and avoiding the use of endangered species.

Abstract
One hundred forty-one children with insulin-dependent diabetes mellitus were screened for serum immunoglobulin A (IgA) antigliadin antibodies by means of an enzyme-linked immunosorbent assay (ELISA) method. None of them had gastrointestinal symptoms, and no major nutritional disturbances were detected except for a girl with moderate growth delay. Twelve patients with positive IgA antigliadin antibodies on two or more consecutive measurements underwent a small intestinal biopsy; four of them had a subtotal villous atrophy, and celiac disease was diagnosed; in another patient, a partial villous atrophy was observed. Children suffering from both diabetes and celiac disease showed an onset of diabetes at a younger age than did nonceliac patients. Prevalence of celiac disease in the screened population is 2.85%, which is higher than in the general population of the Comunidad Valenciana (one in 2,500 live births).

Abstract
In 105 children and adolescents with IDDM, insulin antibodies were detected as a percentage of radiolabelled insulin both at onset of disease and during the first 8 years of treatment. At diagnosis, 29 patients (27%) were insulin autoantibody positive (IAA+). An inverse relationship was found between IAA levels and age at diagnosis. No significant correlation was seen between IAA positivity and HLA antigens, while there was a negative correlation between IAA and C-peptide levels in the second year of the disease. The percentage of insulin antibody (IA) positive patients increased after insulin administration, with a maximum peak between the first and second year of the disease. The IA response to insulin therapy was similar in IAA+ and IAA- patients, while it was greater in younger children. No relationship was found between IA levels and haemoglobin A1c values, daily insulin requirement, HLA and early complications. No difference in either percentage of positivity or IA levels was seen in patients treated continually for the first 5 years of the disease with monocomponent porcine insulin or human insulin. A negative correlation was found between IA and C-peptide levels in the first and second years of the disease. In conclusion, we have shown that, even after many years of disease, neither IAA nor IA, induced in equal measures by current human insulin preparations, have significant effects on the clinical course of the disease.

Abstract
BACKGROUND Although it is known that anaemia may be the only presenting symptom in coeliac disease, prevalence figures of unsuspected coeliac disease in anaemic patients are not available. The aim of this study was to assess the clinical usefulness of antigliadin and antiendomysial antibody tests in the diagnostic algorithm of anaemic patients. METHODS Two hundred consecutive anaemic patients were tested for antigliadin antibodies, and those positive were also tested for antiendomysial antibodies. All patients positive for antigliadin and antiendomysial antibodies underwent intestinal biopsy. RESULTS Sixteen patients were antigliadin antibody-positive, and 10 were also antiendomysial antibody-positive. In all 10 a jejunal biopsy was consistent with coeliac disease (prevalence, 5%). This prevalence rose to 8.5% when patients with macrocytic anaemia or with microcytic anaemia due to previous bleeding or responsive to oral iron therapy were excluded from the calculation. CONCLUSIONS Coeliac disease is a frequent cause of iron-deficiency anaemia, and antigliadin and antiendomysial antibody tests should be always performed in the diagnostic algorithm of anaemic patients.

Abstract
Among 783 patients referred to our institute with different types of seizures as presenting symptom, systematic evaluation of antigliadin and antiendomysial antibodies in the serum has identified nine in whom jejunal biopsy has subsequently confirmed the diagnosis of celiac disease (CD). In three of them brain imaging showed the presence of calcified areas in the occipital region. They had complex partial seizures (CPS), associated in two with transient episodes of blindness. In another patient with CPS and generalized tonic-clonic seizures (GTCS) progressive multifocal cerebral calcifications were noted. In the other six patients with CPS and/or GTCS cerebral calcifications were absent. Symptoms of CD in all these cases were either not previously taken into account, or they were very mild or completely absent. In a group of 36 patients with clinically manifest CD, regular follow-up, and good compliance with the dietary regimen, no clinical seizures were reported. The pathogenetic mechanism and the relationship between epilepsy and an early diagnosis and treatment of celiac disease are discussed.

Abstract
Many attempts have been made to find screening tests for celiac disease to reduce the need for biopsy, or to achieve better selection criteria before intestinal biopsy. We have recently analyzed apparently healthy blood donors for antigliadin antibodies (AGA) to select subjects for further gastrointestinal investigation. A prevalence of gluten enteropathy of at least 1/256 was found in this population. The positive predictive value (+PV), however, was only 20%. In the present study we have analyzed IgA antiendomysium antibodies (IgA-EmA) to estimate the sensitivity and specificity of the test, and determine whether or not the +PV of the assay increases when screening for adult celiac disease in an asymptomatic population. We found that asymptomatic persons with celiac disease may have IgA-EmA. We found a 100% specificity of IgA-EmA in the tested population of blood donors, whereas the sensitivity was about the same as that of IgA-AGA. This result of a +PV of 100% indicates that a positive IgA-EmA could replace biopsy in diagnosing celiac disease. However, further extended studies are needed to determine whether this is applicable in other populations. To screen patients for celiac disease, we recommend the easy and cheap IgA-AGA assay as a preliminary test and the IgA-EmA to verify the diagnosis and avoid unnecessary biopsies.

Abstract
Coeliac disease (CD) is associated with the presence of gliadin antibodies (GA) (IgG and IgA), often used as a screening test for CD. Using a modified micro-enzyme-linked immunosorbent assay for GA, we studied the prevalence of GA in three healthy groups: children (mean age, 12 years), adult blood donors (mean age, 38 years), and healthy women (mean age, 57 years). We also studied the clinical characteristics of the blood donors. On the basis of findings in 27 untreated CD patients, cut-off levels of IgG and IgA antibody titres were chosen to yield a test with relatively low sensitivity (56%) but high specificity (100%). Analysis of IgM antibodies did not improve the sensitivity. Of the 384 12-year-old children, both IgG and IgA GA positivity was found in 15 (3.91%), a rate significantly greater than that in the blood donors (22 of 1537, 1.43%; p < 0.001) or in the middle-aged women (11 of 944, 1.17%; p < 0.0001). Of the 22 GA-positive healthy blood donors, 13 underwent small-bowel biopsy, but only 1 of the specimens manifested histologic changes compatible with CD. The other 12 had normal specimens, including a normal intraepithelial lymphocyte count. The estimated frequency of CD among the blood donors was thus 1 of 1500, a figure consistent with those previously published. We conclude that GA occur frequently in the Swedish population but that their prevalence decreases with increasing age. As a screening test for CD in healthy individuals, the GA titre is of poor predictive value.

Abstract
It is now generally believed that subclinical coeliac disease is common in the general population. We have undertaken screening for this disorder in a school district in central Italy. Screening was divided into three levels: first, IgG and IgA antigliadin antibody (AGA) assay on capillary blood obtained by finger prick; second, AGA plus IgA anti-endomysium antibody (AEA) test and measurement of serum immunoglobulins in venous blood; and third, intestinal biopsy. 3351 students (66% of the eligible population) aged 11-15 years attended first-level screening. 71 (2%) were recalled because of AGA positivity; 18 of these satisfied second-level criteria and underwent intestinal biopsy. Coeliac disease was diagnosed in 11 subjects, most of whom had no serious symptoms. Selective IgA deficiency was found in 4 subjects, 1 of whom also had coeliac disease. The prevalence of subclinical coeliac disease in the study group was 3.28 per 1000. Coeliac disease screening is feasible and involves only slight discomfort to the general population. Such screening can detect large numbers of cases of coeliac disease, which can be treated with a gluten-free diet. Many subclinical cases of coeliac disease would not be detected by screening only a selected group of at-risk patients.

Abstract
We determined the incidence of celiac disease in the western New York area to be 1.29 per 10,000 live births. Celiac disease occurred in 29 children with gastrointestinal symptoms. Two children (1.7%) of 117 with short stature and 10 (4.0%) of 211 with diabetes mellitus had serum anti-endomysial antibodies. We conclude that the incidence of childhood celiac disease in our area is much less than that reported in Europe.

Abstract
The prevalence of underweight, short stature, and abnormal laboratory tests was assessed in a retrospective study of 335 patients with biopsy-verified childhood celiac disease (CCD). Of the patients younger than 2 years old, 67.4% were underweight (body weight: less than - 2SD) and 33.9% were short (height: less than - 2SD). In children older than 2 years, underweight was present in 36.0% of patients; the prevalence of short stature was 50.0%. Therefore, diagnostic procedures related to CCD appear justified in all children with short stature of unknown etiology. However, because 50% of patients were neither short nor underweight, normal height and weight should not preclude workup of a patient with symptoms suggestive of CCD. Of the laboratory tests evaluated, antigliadin antibodies were the most sensitive for CCD. Insulin-like growth factor (IGF-I) serum levels were prospectively studied in 62 patients (32 CCD patients, 30 controls) referred for jejunal biopsy. IGF-I levels were significantly lower in female CCD patients than in control patients. There was a significant negative association between the duration of gluten exposure and IGF-I levels. Results indicate that significant reduction in IGF-I levels in CCD patients occurs only after prolonged gluten exposure but before growth failure. Reevaluation of IGF-I levels on a glutenfree diet showed rapid reversal of reduced IGF-I values.

Abstract
Serum IgA anti-gliadin antibody estimation is a recognized screening method for celiac disease. However, celiac disease is primarily a small intestinal mucosal disorder, and so we have examined the possibility that secreted, mucosal IgA anti-gliadin antibody might provide a more relevant measure of gluten sensitivity than that obtained from serum tests. Serum IgA anti-gliadin antibody and serum, salivary, and small intestinal aspirate IgA anti-gliadin antibody were measured by enzyme-linked immunosorbent assay. Serum IgA and IgG anti-gliadin antibody were markedly increased in untreated celiacs (N = 31) as compared to normals (N = 20) or disease controls (N = 39) (P less than 0.0001). Levels were lower in treated (N = 30) than untreated celiacs (P less than 0.001). In intestinal aspirates both untreated and treated patients had similar levels of IgA anti-gliadin antibody (P = 0.48), but both were significantly higher than in controls (P less than 0.01). Salivary IgA anti-gliadin antibody, by contrast, was not increased in celiac patients as compared to controls. Serum IgA anti-gliadin antibody was the most sensitive (84%) and specific (95%) test for detecting untreated celiac disease. It was also the most useful in patient follow-up where it provides an early objective indicator of adherence to a gluten-free diet. Mucosal IgA responses to gliadin in celiac disease appear to be compartmentalized, with different portions of the gastrointestinal tract functioning as separate immunological organs. Our results also demonstrate that serum and secretory IgA production are under independent control.

Abstract
We studied three groups of patients with coeliac disease: group 1 = 95 adult patients with gastro-intestinal symptoms diagnosed after reaching adult height, 41 of whom had had symptoms during childhood; group 2 = 23 adult patients with classic coeliac disease treated before or during puberty; group 3 = 11 coeliac children with short stature and no gastro-intestinal symptoms diagnosed and treated before or during puberty. We evaluated the adult height in groups 1 and 2 and the growth during the first years of diet in group 3. Our study leads us to the following conclusions. Dieting leads to a modest increase (on average not more than 3 cm) of the final height of coeliac patients. Subjects with gastro-intestinal symptoms who have been treated before adulthood reach a mean height similar to the normal population and have a slightly better adult height than non-treated subjects. This difference seems to exist only in men and this might be related to puberty evolving more rapidly in women receiving treatment. Subjects without symptoms during childhood reach a normal final height even without treatment. In our patients, early treatment seemed to have no great effect on adult height.

Abstract
IgA and IgG antigliadin antibodies were measured in 498 patients with insulin dependent diabetes mellitus and no history of intestinal malabsorption. Thirty patients had abnormal concentrations of antigliadin antibodies; 22 of these had an intestinal biopsy carried out and 16 of the 22 had subtotal villous atrophy suggestive of coeliac disease (prevalence 3.2%). There were no significant differences between patients with coeliac disease and diabetes and diabetic patients with normal IgA antigliadin antibodies in any of the nutritional variables measured, duration of diabetes, and mean insulin requirement. The mean age of onset of diabetes and attainment of expected height for age were both significantly lower in the patients with both diseases. Typing HLA classes I and II was done in 242 patients. The incidence of HLA-B8, DR3, and DQW2, which are commonly associated with both the diseases, is increased when both are present.

Abstract
An enzyme-linked immunosorbent assay was used to measure serum antigliadin antibodies (AGA) of IgG and IgA classes. The assay was modified to measure IgA1 and IgA2 subclasses with monoclonal anti-IgA subclass antibodies. Serum IgG- and IgA-AGA levels were elevated in patients with coeliac disease (CD) but an overlap was seen with control sera. IgA-AGA isotyping using monoclonal anti-human IgA1 and IgA2 antibodies increased the sensitivity and specificity of the assay to almost 100%. All patients with active untreated CD and none of the control groups had elevated IgA1-AGA and IgA2-AGA. In order to measure the relative distribution of IgA1-AGA versus IgA2-AGA an IgA1/IgA2 ratio was calculated. In patients with active untreated CD a ratio of 2.8 was found, declining to 2.2 during treatment. A gluten challenge increased the ratio to 3.4. These findings suggest that IgA1-AGA subclass measurements are a useful screening test before small bowel biopsies are performed. This method can also be used to assess the results of a gluten free diet.

Abstract
Because of the possible clinical association between coeliac disease and sarcoidosis, the incidence of humoral sensitivity to dietary proteins was examined in patients with sarcoidosis. Raised concentrations of circulating IgG antibodies to alpha gliadin were found in 41/99 sarcoid patients whereas antibody levels to casein, beta lactoglobulin and ovalbumin were similar to normal controls. Subsequently, a group of 26 sarcoid patients were selected for small intestinal biopsy; 11 had raised and 15 normal alpha gliadin antibody (AGA) levels. One AGA positive patient had villous atrophy consistent with coeliac disease. Intraepithelial lymphocyte (IEL) counts were raised in AGA positive (median 30; 95% confidence limits 22-46) and AGA negative (median 24; 95% confidence limits 19-32) sarcoid patients when compared with a control group (median 13.5; 95% confidence limits 10-18) p less than 0.01. Serum IgG concentrations were raised in 11/52 patients tested but there was no correlation between IgG levels and the presence of IgG antigliadin antibodies. HLA Dr typing was done in 21 of the 26 biopsied patients. The coeliac disease associated antigen Dr3 was present in eight of 21 (38%) which is very similar to the prevalence in unselected blood donors (34%). There was no significant difference in IEL counts between Dr3 positive and Dr3 negative sarcoid patients. These findings suggest that in patients with sarcoidosis, there is an altered gastrointestinal mucosal immune response, accompanied in about 40% of patients by specific sensitisation to wheat protein.

Abstract
The aim of the present study was to describe linear growth of infants with celiac disease, using the "ICP-growth model". Supine length during the first three years of life was studied longitudinally in 63 infants with diagnosed celiac disease. "Undisturbed" linear growth was seen during the first six postnatal months followed by reduced growth during the second half of the first year. After 1.5 years of age a pattern of catch-up growth was observed, leading to an average attained length at 3 years of age similar to that of the controls. According to the "ICP-growth model", normal linear growth can mathematically be represented during the first 3 years of life by an Infancy component with the addition of a Childhood component, the latter acting from the second half of the first postnatal year. The onset of the Childhood component (assumed to represent the age at which growth hormone begins to influence linear growth significantly) was delayed by about an average of 3 months, which is in agreement with the observed reduction in gain during the second half of the first year of life. Children suffering from celiac disease and with "late" onset of the Childhood component were shorter at 1, 2 and 3 years of age than those with "normal" onset. The results of this investigation show that ICP-based growth charts are helpful in detecting and monitoring growth for children with celiac disease, and indicate a possible mechanism whereby malabsorption (and perhaps secondary malnutrition) leads to reduced growth velocity.

Abstract
Genetic and environmental factors (breast feeding, probably viral infections) play a role in the expression of the disease. Prevalence of GSE in childhood did not substantially decrease in the last 15 years in all European countries, where GSE is still more common in infantile age and presents frequently gastrointestinal symptoms. A decrease has been reported in childhood in several United Kingdom areas and in Finland, where the clinical presentation is changing, shifting upward with age and coming closer to the adult type of the disease. The following clinical problems have been reported in the recent literature: enamel hypoplasia; monosymptomatic short stature; arthritis and other immunologic diseases; association with diabetes, atopy, Iga deficiency, and probably Down's syndrome. Delay in puberty and other peculiar problems of the disease have been described in adolescents. Tests assessing the permeability of the small intestine and the blood levels of antigliadin antibodies have recently gained success as noninvasive tools for the diagnosis of the GSE. The gluten should be withdrawn from the diet and the challenge with gluten should be performed not before 12 months of gluten-free diet with an accurate timing of the biopsy on the basis of the antigliadin and antireticulin antibodies, to avoid clinical and growth damage. Celiac children do require a permanent gluten-free (and not poor) diet. In reality, too many celiac adolescents are off-diet.

Abstract
Short stature is a common pediatric problem that requires us to decide whether a child's small size represents only normal variation or indicates the presence of an underlying disease. In a population of children two standard deviations (SD) below the mean for height (below the third percentile), about 20 per cent may be expected to have pathologic short stature with the remaining 80 per cent about equally divided between familial short stature and constitutional growth delay. In contrast, most children three SD below the mean for height have pathologic short stature. Set forth in this article is an orderly approach to identify normal variants of short stature and to investigate the causes of pathologic short stature.
