Progressive cerebral calcifications, epilepsy, and celiac disease

Gluten sensitivity and epilepsy: a systematic review

OBJECTIVE

The aim of this systematic review was to establish the prevalence of epilepsy in patients with coeliac disease (CD) or gluten sensitivity (GS) and vice versa and to characterise the phenomenology of the epileptic syndromes that these patients present with.

METHODOLOGY

A systematic computer-based literature search was conducted on the PubMed database. Information regarding prevalence, demographics and epilepsy phenomenology was extracted.

RESULTS

Epilepsy is 1.8 times more prevalent in patients with CD, compared to the general population. CD is over 2 times more prevalent in patients with epilepsy compared to the general population. Further studies are necessary to assess the prevalence of GS in epilepsy. The data indicate that the prevalence of CD or GS is higher amongst particular epileptic presentations including in childhood partial epilepsy with occipital paroxysms, in adult patients with fixation off sensitivity (FOS) and in those with temporal lobe epilepsy (TLE) with hippocampal sclerosis. A particularly interesting presentation of epilepsy in the context of gluten-related disorders is a syndrome of coeliac disease, epilepsy and cerebral calcification (CEC syndrome) which is frequently described in the literature. Gluten-free diet (GFD) is effective in the management of epilepsy in 53% of cases, either reducing seizure frequency, enabling reduced doses of antiepileptic drugs or even stopping antiepileptic drugs.

CONCLUSION

Patients with epilepsy of unknown aetiology should be investigated for serological markers of gluten sensitivity as such patients may benefit from a GFD.

Neurological Complications of Gastrointestinal Disease

There is a growing interest in the extraintestinal manifestations of common pediatric gastrointestinal diseases, such as inflammatory bowel disease and celiac disease. This article specifically focuses on the neurological symptoms that manifest because of these disorders and their treatments. Many neurological symptoms have been reported in association with these diseases, including neuropathy, myopathy, ataxia, headache, and seizures, among others. It is currently believed that these neurological symptoms are largely overlooked by practitioners and could be a red flag for earlier diagnosis. However, additional research, especially in the pediatric population, is warranted to further elaborate on the causality and pathophysiology of these neurological symptoms.

Epilepsy, occipital calcifications, and oligosymptomatic celiac disease in childhood

The association of epilepsy, occipital calcifications, and celiac disease has been recognized as a distinct syndrome. The objective of this study was to present the clinical, electrophysiologic, and neuroradiologic features in a series of patients with this syndrome. Thirty-two patients with the constellation of epilepsy, occipital calcifications, and celiac disease were identified in our epilepsy clinic. The mean age was 11 years and the mean length of follow-up was 7.4 years. The 1990 criteria of the European Society of Pediatric Gastroenterology and Nutrition were used to diagnose celiac disease. The Kruskal-Wallis statistics test was employed with a signficance of P < .05. Thirty-one patients had partial seizures, 21 of them with symptoms related to the occipital lobe. In most patients, the epilepsy was controlled or the seizures were sporadic. Three developed severe epilepsy. Occipital calcifications were present in all cases. Computed tomography in 7 patients showed hypodense areas in the white matter around calcifications, which decreased or disappeared after a period of gluten-free diet in 3 patients. A favorable outcome of epilepsy was detected in patients with the earliest dietary therapy. This study presents the largest series of children with this syndrome outside Italy. White-matter hypodensities surrounding calcifications are rarely reported. A prompt diagnosis of celiac disease might improve the evolution of the epilepsy and may improve cognitive status.

Calcificação intracraniana occipital bilateral, epilepsia e doença celíaca: relato de caso

Relatamos o caso de uma menina com 6 anos de idade que apresentava episódios recorrentes de diarréia desde os 6 meses de vida associada a anemia ferropriva com desenvolvimento neuromotor normal. Aos 3 anos de idade começou a apresentar crises parciais que foram controladas com carbamazepina. Tomografia computadorizada de crânio aos 5 anos demonstrou calcificações girais grosseiras nas regiões occipital e parietal posterior bilateralmente. A ressonância magnética de crânio evidenciou áreas de hipossinal em T2 na região parieto-occipital bilateralmente. Realizou investigação para síndrome de mal absorção incluindo estudo da função digestivo/absortiva (teste D-xilose), avaliação sorológica (anticorpos antigliadina, antiendomísio e antitransglutaminase) e biopsia de intestino delgado que demonstrou intensa atrofia de vilosidades com infiltrado linfoplasmocitário no córion compatível com doença celíaca.

Association between coeliac disease, epilepsy and brain atrophy

Patients with epilepsy and posterior cerebral calcifications have an increased risk of coeliac disease (CD). The occurrence of this syndrome and the overall risk of CD and epilepsy remain still poorly understood. This study presents the prevalence of CD, brain atrophy, and cerebral calcifications in patients with epilepsy of unknown aetiology. The medical records of 900 consecutive adult patients with epilepsy diagnosis were reviewed. The occurrence of CD in living patients with epilepsy of unknown aetiology (n = 199) was investigated; all patients without previously known CD were asked for serological screening for the disease and the diagnosis was verified with small bowel biopsy. The presence of occipital calcifications and brain atrophy in all available CT scans (n = 130) was evaluated. Five of 199 cases had prior history of CD. The prevalence of definite CD in the patients was 2.5% (5/199), which is significantly higher that the current prevalence of CD in our area (0.27%). Antibody testing and small bowel biopsy in positive cases failed to increase prevalence of CD. Eleven (8.5%) patients had intracerebral calcifications and 3 of them posterior calcifications; all 11 had negative screening results for CD. Four (80%) patients with definite CD had supratentorial brain atrophy compared with 33 (26%) of 125 patients without CD. Prevalence of CD was increased among patients with epilepsy of unknown aetiology, but the combination of CD, epilepsy and intracranial posterior calcifications was rare in Finnish adult epilepsy population.

Meningo-cortical calcifying angiomatosis and celiac disease

A woman with ophthalmic migraine was found to have bilateral cerebellar and cerebral calcifications. She progressively developed severe intracranial hypertension, with swelling of the brain and downward transtentorial and tonsillar herniation. Because steroid treatment was ineffective, the right occipital pole was resected. Histological study demonstrated meningo-cortical calcifying angiomatosis. Within 2 months, brain swelling and papilledema disappeared. Subtle signs of malabsorption led to the hypothesis of celiac disease, confirmed by jejunal biopsy. Similar cerebral histological findings have been reported in the brain of two young patients affected by epilepsy and celiac disease. The association between cerebral calcifications and celiac disease is peculiar; the pathogenetic relationship is unknown.

Partial seizures, cerebral calcifications and celiac disease

We describe the case of a 25 year old woman who has been clinically and instrumentally examined over a period of about 20 years. A diagnosis of celiac disease was made when she was four years old and, ten years later, CAT revealed the presence of bilateral cerebral calcifications. The partial occipital seizures were controlled by adopting a gluten-free diet, which is still being followed four years after the discontinuation of anti-epileptic treatment.
