Linear growth and skeletal maturation in subjects with treated celiac disease.

BACKGROUND: The aim of this study was to report on the long-term growth and development in a group of treated patients with celiac disease. METHODS: The study includes 26 patients (11 boys and 15 girls) with typical celiac disease who were younger than 2.5 at diagnosis and were followed by means of a growth longitudinal monitoring from the introduction of a gluten-free diet (mean age, 1.7 +/- 0.5 years) until adulthood, over a median period of 15.3 years. Growth indicators used were: height, skeletal age, weight and BMI. RESULTS: At the time of admission, the patients had a general tendency to short stature, underweight and retarded skeletal maturation. They did not catch up completely in height and skeletal age after a dietary treatment period of 3 years. Most of them were seen to be slightly below average height for age during childhood and adolescence with skeletal maturity retardation, even if a fairly large interindividual variation of height profiles was evident. CONCLUSIONS: Notwithstanding the early treatment, the careful follow-up, and the good adhesion to the dietary rules of the patients under study, slight negative effects of the disease on growth were not avoided.

Celiac disease and Turner syndrome.

BACKGROUND: Short stature is one of the features of Turner syndrome and a form of presentation of monosymptomatic celiac disease. METHODS: The recognition of celiac disease in two antiendomysium antibody-positive Turner syndrome girls who did not respond to growth hormone treatment led us to perform as a screening for celiac disease IgA and IgG antigliadin antibodies and antiendomysium antibodies determination in other 35 Turner syndrome patients. Intestinal biopsy was proposed to the antiendomysium antibodies-positive girls; in the former, subtotal villous atrophy was found; in the latter, one parent's consent for intestinal biopsy was not obtained. RESULTS: The prevalence of celiac disease in Turner syndrome patients observed in the present study (8.1 if we consider 3 villous atrophy, 10.8 if we consider 4 antiendomysium antibody-positive) is quite high and seems to indicate that the association of these two disorders could not be coincidental. As to the clinical picture, celiac disease appeared atypical in one case, typical in another one and as a silent form in the third case. Of the 3 cases with villous atrophy on gluten-free diet growth hormone therapy was not effective in two girls, who were older than 16 years, while in the younger patient, detected by the screening, a significant increment of height velocity and height Standard Deviation Score for Chronological Age according to Turner references was observed. CONCLUSIONS: This study suggests that celiac disease can be associated with Turner syndrome and even responsible for a failure of growth hormone therapy. Therefore we propose to perform in Turner syndrome patients antiendomysium antibody determination as a screening followed by intestinal biopsy in positive cases. This would be advisable at least before starting growth hormone treatment.

Genetic contribution of the HLA region to the familial clustering of coeliac disease.

In order to assess the effect of the HLA region on familiality of coeliac disease (CD), we carried out a study on 121 CD index cases and 325 first degree relatives. The transmission disequilibrium test confirmed the importance of the HLA-DR3 haplotype in CD susceptibility. However, the different distortion found in affected children inheriting maternal or paternal DR3 alleles suggested that the sex of the parent might influence the risk conferred by this haplotype. The increase in risk to siblings of affected individuals relative to the risk in the general population (lambda s) and the contribution of the HLA genes to this clustering (lambda sHLA) have also been estimated. Non-overlapping data from the literature have been collected and combined with our sample to extend such analysis. Then, the percentage contribution of the HLA region to the development of CD among siblings was 36.2%. This result confirms that the HLA genotypes are an important genetic background to CD development but shows that additional susceptibility factors remain to be identified.

Frequency and clinical pattern of celiac disease among siblings of celiac children.

To investigate the prevalence and clinical and genetic patterns of celiac disease (CD) among siblings of CD patients, 103 siblings and one twin of 80 celiac children were evaluated by means of their clinical history, physical examination, blood indices of nutritional status, and antigliadin antibodies (AGA). Antiendomysium antibody (AEA) levels were determined in 70 patients and 85 subjects were human leucocyte antigen (HLA) typed. On the basis of clinical or laboratory data or both, 21 siblings (20.2%) were submitted to intestinal biopsy, whereas intestinal biopsy in six siblings with positive serologic screening (AGA IgA or AEA or both) was not performed because of parental refusal. In a high percentage of cases (18%), all on a gluten-containing diet, the intestinal mucosa was atrophic, and CD was subsequently diagnosed. Because we could not submit all the siblings to intestinal biopsy, this figure could underestimate the real prevalence of the disease in our series; consequently, it was not possible to calculate accurately the sensitivity and specificity of AGA and AEA. Nevertheless, AEA (positive in all the nine siblings with mucosal atrophy), followed by AGA IgA, proved to be the best screening for CD. Eighteen of 19 CD siblings showed HLA-predisposing antigens. Among the 19 CD siblings, one showed a typical form with gastrointestinal symptoms, two had short stature, one suffered from recurrent vomiting, and in 15, the disease was clinically silent. On the contrary, among siblings who were first diagnosed (index cases), the majority (73.7%) had a typical form of CD, and no clinically silent cases were observed. We did not find any difference between index cases and CD siblings in food habits and distribution of HLA antigens. In 15 of 18 cases, the sibling diagnosed subsequently was the older one. Finally, the typical form of CD was significantly more frequent among the younger brother than the older. In conclusion, the high prevalence of the silent form of CD in our cases indicates that siblings of CD subjects should always be screened for CD. The combination of AGA IgA and AEA represent a good screening method to use in selecting children for the intestinal biopsy.

Down syndrome and coeliac disease: usefulness of antigliadin and antiendomysium antibodies.

The usefulness of antigliadin (AGA) and antiendomysium antibodies (EMA) as a screening test for coeliac disease (CD) in 113 Down syndrome (DS) patients (61 children) was evaluated. AGA IgA were present in 22.1%, AGA IgG in 48.6%, EMA in 6.2%. Four symptomatic patients, AGA- and EMA-positive, were affected by CD (3.5%). In three AGA-positive and EMA-positive subjects, permission for intestinal biopsy was refused, while in two AGA-positive and EMA-negative children, the intestinal mucosa was normal. Our study confirms the association of CD and DS, and suggests the usefulness of EMA determination as a test for selecting DS patients for intestinal biopsy.

Relapsing polychondritis in childhood: a rare observation studied by CT and MRI.

Relapsing polychondritis is very rare in children. The diagnosis must be based on a combination of clinical and pathologic features. CT is very useful for an accurate and rapid assessment of laryngo-tracheo-bronchial involvement and the typical finding is lumen narrowing by wall thickening and collapse of the supporting cartilaginous structures. The role of MR imaging should be complementary to CT.

[Anti-gliadin antibodies in the diagnosis and follow-up of celiac disease].

The study assessed the value of anti-gliadin antibodies (AGA) as a diagnostic test for celiac disease (CD) by examining 219 children: 57 were affected by malabsorption syndrome and underwent the first duodenojejunal biopsy; 83 underwent a secondary diagnostic phase for CD; 44 underwent a challenge test; 35 controls. Duodenojejunal biopsy was performed in all subjects in the three stages of diagnosis for CD. By comparing AGA levels and on the basis of histological tests of duodenojejunal mucosa it is possible to confirm the reliability of the method as a screening test for use in subjects whose clinical symptoms suggest CD. AGA are however less reliable in the second and third stages, that is to say in the follow-up of CD, since they do not always reflect the conditions of intestinal mucosa.

The prevalence of rubella infection in Somalia.

A serological survey was carried out to determine the rubella antibodies among Somalian population with an enzyme-linked immunosorbent assay (ELISA). The prevalence of rubella infection in Somalia was found to be 65.6%. Rubella immunity rises with increasing age of subjects from the second year of life.
