SUMMARYObjective: Epilepsy in Ehlers-Danlos syndrome (EDS) has been reported in the literature, but there are no studies that have investigated in detail clinical and electroencephalography (EEG) features in patients with EDS, and that have compared the outcome of epilepsy in subjects with or without brain lesions. We report a series of 42 patients with EDS and epilepsy, including data that concern clinical characteristics, EEG abnormalities, brain malformations at magnetic resonance imaging (MRI) and long-term outcome. Methods: EEG, clinical information, and neuroimaging characteristics in 42 patients with EDS were analyzed at the onset of epilepsy and after long-term follow-up (at least 5 years). We subdivided the patients into two groups: group A, 26 patients without brain abnormalities; group B, 16 patients with brain lesions, often with periventricular heterotopia (PH). Results: Group A patients: Most cases (19 of 26) presented focal epilepsy, whereas 7 of 26 were affected by generalized epilepsy; interictal EEG showed temporal or temporoparietal spikes in most cases. Twenty-three patients received antiepileptic drug (AED) monotherapy; three patients were treated with polytherapy. During follow-up, all patients were seizure-free for at least 2 years, and only one continued to receive AEDs. Group B patients: the majority presented focal epilepsy (9 of 16), but many patients had generalized epilepsy (7 of 16); interictal EEG showed usually frontal or frontotemporal spikes and waves. Many patients (12 of 16) received AED polytherapy. During followup, 12 patients were seizure-free, and all patients continued pharmacologic treatment. Significance: All patients without brain lesions showed a favorable response to AED monotherapy and were seizure-free after a few years of treatment. Patients with central nervous system abnormalities had a worse outcome, suggesting that the presence of brain lesions could influence the long-term evolution in these patients.

The clinical spectrum for celiac disease (CD) is broad and includes cases with either typical (intestinal) or atypical (extraintestinal) features, often making the diagnosis of CD very difficult.We describe the case of a girl presenting with stunted growth and malnourishment. She was evaluated at 14 months for decreased growth rate without any signs of gastrointestinal, renal or endocrine disorders. She was evaluated for CD, but resulted negative for anti-tTG antibodies.At the age of 4.1 years, she exhibited basal dental enamel hypoplasia, iron deficiency anaemia despite repeated iron supplementation, with persistent reduced height (-2.79 SDS), BMI (-0.76 SDS), growth velocity (-1.79 SDS) and delayed bone age (1.5 year). The CD screening was repeated and very high anti-tTG-IgA (128 IU/ml, normal values < 7 IU/ml) and anti-tTG-IgG (77 IU/ml, normal values < 7 IU/ml) values were found. HLA genotyping revealed an HLA DQ2 haplotype. A duodenal biopsy revealed severe villous atrophy with crypt hyperplasia and increased intraepithelial lymphocytes (> 40 IELs/100 epithelial cells) confirming the diagnosis of CD. A gluten-free diet was started and after only four months, her growth velocity increased from 4.83 cm/year (-1.79 SDS) to 6.53 cm/year (-0.15 SDS).In conclusion, we report the development of a positive serology for CD in an asymptomatic child with growth retardation, who previously was investigated for CD and resulted negative. Therefore, when faced with retarded growth in young patients, after excluding other malabsorption conditions and even when CD serological markers are negative, the paediatric endocrinologist should request HLA genotyping, before the intestinal biopsy, in order to check for the presence of risk alleles.
