Abstract
Over the last decade, there have been significant advances in the identification, characterization, and treatment of autoimmune neurologic disorders in children. Many of these diseases include a typical movement disorder that can be a powerful aid to diagnosis. Frequently, movement disorders in autoimmune conditions are the sole or among a few presenting symptoms, allowing for earlier diagnosis of an underlying malignancy or systemic autoimmune disease. Given that early detection and treatment with immunotherapy may confer improved outcomes, recognizing these patterns of abnormal movements is essential for child neurologists. The purpose of this review is to summarize the clinical characteristics, diagnosis, and treatment of movement disorders that occur in pediatric autoimmune disorders.

[PMID: 25596648 DOI: 10.1016/j.ijporl.2014.12.031] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2014] [Revised: 12/17/2014] [Accepted: 12/22/2014] [Indexed: 11/18/2022]
Abstract
OBJECTIVES Celiac disease (CD) is a chronic immune-mediated enteropathy caused by the ingestion of gluten in genetically predisposed individuals. In some reports, sensorineural hearing loss (SNHL) has been identified as an extraintestinal symptom of CD. We aimed to further investigate the possible association between CD and SNHL by examining a greater number of pediatric CD patients. METHODS The study was carried out from March to September 2014 and included 110 pediatric patients with biopsy-confirmed CD (220 ears) and 41 age- and sex-matched controls (82 ears); participants were evaluated by tympanometry and pure tone audiometry (frequency, 250-8000Hz frequency). RESULTS Audiometric bone conduction thresholds were significantly different between the CD patients and the controls (p<0.05), but there were no significant differences in pure tone averages for air conduction (p>0.05). When the results for CD patients were analyzed according to duration of disease (≤36 months and >36 months), a significant difference in bone conduction thresholds (p<0.05) was noted, with significant increments at the later stages of disease. However, this difference was not sufficient to define clinical hearing loss, as the pure tone average thresholds remained below 20dB. CONCLUSION These results indicate that subclinical hearing loss may be present in children with CD, which could presage more serious hearing impairments at older ages and later stages of the disease. Hearing screenings should be recommended for children with CD in order to prevent the potentially unfavorable effects of hearing loss on the emotional, behavioral, cognitive, and sensorimotor development of these patients.

Abstract
OBJECTIVE Although it is well known that celiac disease (CD) is associated with neurologic disorders, association with psychiatric problems is not well defined. In this report, we aimed to detect CD prevalence in patients with attention-deficit hyperactivity disorder (ADHD). METHODS A total of 362 patients between the ages 5 and 15 years with the diagnosis of ADHD according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) diagnostic criteria and 390 sex- and age-matched healthy children were included in the present study. Serum levels of tissue transglutaminase (tTg) immunoglobulin (Ig) A and IgG were studied in both groups. Serum IgA levels were also studied in patients with positive tTG IgG for the exclusion of selective IgA deficiency. Endoscopic duodenal biopsy was provided in seropositive patients, whose parents approved the procedure. Biopsy samples were evaluated according to Marsh-Oberhuber classification. RESULTS tTg IgA was positive in 4 patients with ADHD (1.1%). Endoscopic duodenal biopsy was suggestive of CD in one of them (0.27%). tTg IgA was positive in 3 of control group patients (0.8%). Duodenal biopsy of the only patient from control group, who underwent upper gastrointestinal endoscopy, revealed normal intestinal mucosa. CONCLUSIONS The seropositivity rates for CD were found similar in ADHD and control groups. Thus, neither routine screening for CD nor empirical recommendation of gluten-free diet seems necessary in children with ADHD.

Abstract
Neurologic complications of celiac disease (CD) include ataxia and peripheral neuropathy, which can be the presenting symptoms and signs. Early diagnosis and intervention could prevent development of further neurologic and systemic complications. Questions remain regarding the prevalence of the neurologic complications, the pathophysiological mechanisms, and the effectiveness of therapy or response to a gluten-free diet.

Abstract
Sporadic adult-onset ataxia of unknown etiology (SAOA) denotes the non-hereditary degenerative adult-onset ataxia disorders that are distinct from multiple system atrophy (MSA). Rather than being a defined disease entity, SAOA has to be regarded as a group of disorders of unknown etiology that are defined by a common clinical syndrome and the exclusion of known disease causes. Epidemiological studies have revealed prevalence rates ranging from 2.2 to 8.4 per 100000, which are higher than those of hereditary ataxias. Clinically, SAOA is characterized by a slowly progressive cerebellar syndrome starting around the age of 50 years. About one-third of SAOA patients have either polyneuropathy or pyramidal tract involvement accompanying cerebellar ataxia. Cognitive impairment is not the rule, and, if present, is only mild. More than half of SAOA patients have signs of mild autonomic dysfunction that do not meet the criteria of severe autonomic failure required for a diagnosis of MSA. Neuropathological and imaging studies show an isolated cerebellar cortical degeneration with no or only mild brainstem involvement. There is no established therapy for SAOA.

Abstract
BACKGROUND The high prevalence of gluten sensitivity in patients with stiff-person syndrome (SPS) lead us to investigate the relationship between gluten sensitivity and GAD-antibody-associated diseases. METHODS We used ELISA assays for anti-GAD and for serological markers of gluten sensitivity. Patients were recruited from clinics based at the Royal Hallamshire hospital, Sheffield, UK. Patients with gluten sensitivity were followed up after the introduction of a gluten-free diet and serological testing was repeated. RESULTS Six of seven (86%) patients with SPS were positive for anti-GAD, mean titre 109 U/ml; This compared with 9/90 (11%) patients with idiopathic sporadic ataxia, mean titre 32 U/ml, 16/40 (40%) patients with gluten ataxia, mean titre 25 U/ml, and 6/10 patients with type 1 diabetes only, mean titre 8 U/ml. None of 32 patients with celiac disease only, and of 40 patients with genetic ataxia were positive for anti-GAD. The titre of anti-GAD reduced following the introduction of a gluten-free diet in patients with SPS who had serological evidence of gluten sensitivity. The same was observed in patients with gluten ataxia and anti-GAD antibodies. This was also associated with clinical improvement. CONCLUSION These findings suggest a link between gluten sensitivity and GAD antibody-associated diseases.

Abstract
AIM The aim of this article was to review and conduct a meta-analysis of the paediatric literature on the neurology of coeliac disease. METHOD We conducted a review of paediatric studies published in English assessing neurological illness in coeliac disease identified through a MEDLINE search (1950-2009). Calculation of computed relative risk, odds ratio, and risk difference was performed using the fixed effect method if applicable. RESULTS Fifteen studies were analysed (11 772 participants). The meta-analysis showed that (1) the relative risk of epilepsy in individuals with coeliac disease, and of coeliac disease in individuals with epilepsy, compared with the general population, was 2.1 and 1.7, respectively, and the risk difference was close to zero, indicating that it was probably a chance association; and (2) the relative risk of headache in individuals with the disease compared with comparison groups was 3.2. In two studies, cerebellar ataxia was documented in 2.7 to 5.4% of participants; in two further studies, the risk of cerebellar dysfunction was zero. Two studies found an association between coeliac disease and peripheral neuropathy. Brain white matter lesions were recorded in two other studies. An association between autism and coeliac disease is disputed. Interpretation Children with coeliac disease are at risk of developing neurological complications, but the risk is lower than in adulthood. The discrepancy might be due to short disease duration, early elimination of gluten from the diet, stricter adherence to diet, or different susceptibility to immune-mediated disorders.

Abstract
Humoral immune mechanisms may have a role in the neurological complications of celiac disease (CD). We assessed 71 CD patients for neurologic manifestations and presence of serum antibodies to neural antigens. Sixteen patients (22.5%) were found to have neurological deficits including headache, depression, entrapment syndromes, peripheral neuropathy, and epilepsy. Antibody reactivity to neural antigens was detected in 30/71 (42.2%) patients. There was no clear correlation between anti-neural reactivity and neurologic dysfunction. Follow-up of 62 patients did not reveal change in electrophysiology or antibodies, regardless of diet. However, in 2 patients with neuropathy, symptoms improved or worsened depending on the diet.

Abstract
We report the case of a woman with refractory celiac disease who developed abnormal spontaneous movements of the extremities and face consistent with myorhythmia. Investigation led to a diagnosis of encephalitis, confirmed by postmortem examination. The movements were likely caused by nonparaneoplastic encephalitis associated with refractory celiac disease. Etiologic and diagnostic considerations and treatment options are discussed.

Abstract
Antibodies to gangliosides and Purkinje cells have been reported in patients with celiac disease (CD) with neuropathy and ataxia, respectively. Whether these antibodies are pathogenic is not clear. The response of neurological symptoms and antibody titers to a gluten-free diet is still controversial. The objective of our study was to assess whether neurological manifestations in CD patients correlate with antibody titers and a gluten-free diet.Thirty-five CD patients (9 males, 26 females, mean age 37.1 +/- 12.6 yrs) were followed prospectively. At initial evaluation, 23 were on a gluten-free diet, 12 were not. At recruitment and during follow-up, patients underwent neurological and electrophysiological evaluation. IgG, IgM, and IgA anti-ganglioside antibodies were assayed by ELISA; anti-neuronal antibodies were assessed by immunohistochemistry and Western blot. Four patients, all males, had electrophysiological evidence of neuropathy; three had been on a gluten-free diet for several months, and one was newly diagnosed. One had reduced tendon reflexes; another complained of distal paresthesias. With regard to anti-ganglioside antibodies, three patients had a moderate increase in antibodies without symptoms or signs of neuropathy. No patients had ataxia or cerebellar dysfunction, although in four patients reactivity to neuronal antigens was found. In 17 patients, an electrophysiological follow-up (mean duration of follow-up, 9 months) showed no changes. In conclusion, the preliminary results of this prospective study indicate that neuropathy, usually subclinical, may accompany CD. Antibody titers do not seem to correlate with neurological symptoms/signs or diet. Ongoing follow-up will help confirm these data and clarify the role, if any, of antibodies in neurological involvement in CD.

Abstract
UNLABELLED Celiac disease (CD/ Nontropicalsprue, gluten-sensitive enteropathy) is a malabsortive condition in which an allergic reaction to the cereal grain-protein gluten (present in wheat, rye and barley) causes small intestine mucosal injury. The onset is in the first four decades of life, with a female to male ratio of 2:1. It may be associated with a wide spectrum of neurological manifestations including cerebellar ataxia, epileptic seizures, dementia, neuropathy, myopathy and multifocal leucoencephalopathy. We report three patients with neurological manifestations related with CD: one with cerebellar ataxia, one with epilepsy and one with cognitive impairment. The diagnosis of CD was confirmed by serologic tests (antiendomysial and antigliadin antibodies) and biopsy of the small intestine. In two patients the neurological symptoms preceded the gastrointestinal abnormalities and in all of them gluten restriction failed to improve the neurological disability. CONCLUSION CD should be ruled out in the differential diagnosis of neurological dysfunction of unknown cause, including ataxia, epilepsy and dementia. A gluten free diet, the mainstay of treatment, failed to improve the neurological disability.

Abstract
BACKGROUND Emerging evidence points to humoural mechanisms in neurological complications of coeliac disease. Immunoglobulin G anti-ganglioside antibodies have been reported in coeliac disease patients with neuropathy, suggesting an immune response to peripheral nerve antigens. No data are so far available on anti-ganglioside antibodies in coeliac disease children or on antibody modifications after gluten-free diet. AIM To evaluate the presence of antibodies to ganglioside antigens in children with coeliac disease, their modification after gluten-free diet, and possible correlations with neurological manifestations. METHODS Sera from 42 coeliac disease children, before and after gluten-free diet, were tested by enzyme-linked immunosorbent assay for the presence of antibodies (immunoglobulin M, immunoglobulin A, immunoglobulin G) to gangliosides. Thirty-five sera of age-matched children with dyspepsia were used as control. RESULTS High anti-ganglioside antibodies titres were present in two patients. In one patient, antibody titre reversed after gluten-free diet, whereas in the other one the titre increased after diet. Neither one complained of neurological symptoms. CONCLUSIONS Anti-ganglioside antibodies do not seem to correlate with gluten ingestion or with neurological manifestations in children with coeliac disease. Mechanisms different from gluten exposure may be implicated in the antibody production. An ongoing prospective study will help clarify the role, if any, of these antibodies in coeliac disease.
