ABSTRACT
Objective To investigate the clinical,imaging,intestinal pathological characteristics and prognosis of gluten ataxia (GA).Methods The clinical data,treatment and prognosis in a patient with GA that was confirmed by pathology and hospitalized in the Department of Neurology,China-Japan Friendship Hospital in July 2018,were analyzed retrospectively.The related literature was reviewed and the clinical feature was summarized.Results The patient is a 41-year old man.He suffered from progressive cerebellar ataxia,and the brain magnetic resonance imaging exhibited diffused cerebellar atrophy.Serum human leukocyte antigen (HLA) tests showed that the patient carried HLA-DQ2 genotype.IgA type anti-gliadin antibody was positive (39.39 RU/ml).Duodenoscopy biopsy revealed mild villus atrophy and lymphocytic infiltration,indicating celiac disease.The diagnosis of GA was established then and the patient was administered gluten-free diet combined with intravenous immunoglobulin,which markedly improved the cerebellar symptoms and signs of cerebellar speech,walk capability and daily living activities.He could do long distance driving independently two months later.Conclusions GA is one of immune-mediated reversible acquired cerebellar ataxia caused by gluten sensitivity.The genotype,serologic features,and clinical phenotype of GA in Chinese mainland population might be similar with those in European and American countries.
ABSTRACT
The aim of this research was to estimate the prevalence of gluten sensitivity in neurologic diseases of unknown etiology and to determine their clinical and biological characteristics in a Moroccan population. Patients and Methods: A prospective case-control study was performed on 60 patients and 57 controls. Patients and controls underwent a screening for IgG and IgA anti-gliadin antibodies (ELISA anti-Gliadin, Orgentec, threshold: 12 IU/ml), and IgA anti-tissue transglutaminase antibodies (ELISA IgA-tGTA, DRG, threshold: 10 IU/m). Results: The median age of patients was 43±13.91 years (ranges: 13-67), versus 39.4±9.12 (ranges: 19-58) for controls. Male to female sexe-ratio was 0.7 for patients vs 2.1 for controls. IgG and/or IgA anti-gliadin antibodies (AGA) were positive in 26.7% of cases (n=16) vs 15.8% (n=9) in controls (p=0.15), while IgA-tTGA was negative in all patients, but positive in 1 control. Positive AGA cases corresponded to peripheral neuropathy (n=4), ataxia (n=3), ischemic stroke (n=3), myopathy (n=2), and 1 case for each of the following conditions: multiple sclerosis, epilepsy, cerebral thrombophlebitis and myelopathy. Among the positive AGA cases, IgA isotype was more prevalent, but IgG AGA titers were higher and clinically more relevant. Conclusion: Gluten Sensitivity is a potential cause of unknown etiological neurologic diseases in young adults, particularly peripheral neuropathy, ataxia and ischemic stroke. AGA testing especially IgG isotype might be a suitable marker to screen for gluten neuropathies.
ABSTRACT
La enfermedad celíaca es una enfermedad autoinmune que cursa con procesos inflamatorios en la mucosa del intestino delgado. Se produce por la ingesta de una fracción proteica del gluten de la dieta en individuos genéticamente predispuestos. Tiene diferentes formas de presentación que van desde la sintomática, típica o atípica, hasta la silente. La detección de autoanticuerpos con diversas especificidades debe ser considerada como indispensable en todos aquellos enfermos donde predominan síntomas digestivos y afectaciones nutricionales, aunque no deben descartarse otras sintomatologías atípicas como son el retraso en el crecimiento y desarrollo. En nuestro trabajo se estudió la presencia de anticuerpos antigliadina y antitransglutaminasa en el suero de 110 enfermos con clínica sugestiva de enfermedad celíaca, y se detectaron anticuerpos en 23 enfermos: 11 con antigliadina, antitransglutaminasa y biopsia positiva; 6 con antigliadina positiva, antitransglutaminasa negativa y biopsia positiva y 6 con antigliadina positiva, antitransglutaminasa negativa y biopsia negativa.
Celiac disease is an autoimmune entity with inflammatory processes in small intestine. It is caused by ingesta of gluten protein fraction in the diet of subjects with genetic predisposition subjects and has different ways of presentation including the symptomatic, typical or atypical and silent type. The detection of autoantibodies with diverse specificities must to be considered as essential in all those patients where there is predominance of digestive symptoms and nutritional affections without to rule out other atypical symptomatologies including the growth and development retard. The objective of present paper was to study the presence of anti-gliadin and anti-transglutaminase in serum of 110 patients presenting with celiac disease and it was possible to detect antibodies in 23 patients: 11 with anti-gliadin and anti-transglutaminase and a positive biopsy; 6 with positive anti-gliadin, negative anti-transglutaminase and a positive biopsy, negative anti-transglutaminase and also a negative biopsy.
