[Celiac disease and ischemic stroke].

BACKGROUND

Neurological manifestations of celiac disease are various. An association with ischemic stroke is not common and has not been well documented. We report two cases.

METHODS

The first patient had experienced several transient ischemic strokes in the past 2 years and then had an acute ischemic stroke involving the territory of the right posterior cerebral artery. Investigations revealed celiac disease with no other recognizable etiology. The clinical course was marked by persistent visual aftereffects, but no new vascular event. The second patient had been followed since 1998 for celiac disease confirmed by pathology and serology tests. She was on a gluten-free diet. The patient had an ischemic stroke involving the territory of the left middle cerebral artery. Apart from a positive serology for celiac disease and iron deficiency anemia, the etiological work-up was negative.

CONCLUSIONS

The mechanisms of vascular involvement in celiac disease are controversial. The most widely incriminated factor is autoimmune central nervous system vasculitis, in which tissue transglutaminase, the main auto-antigen contributing to maintaining the integrity of endothelium tissue, plays a major role. Other mechanisms are still debated, mainly vitamin deficiency.

CONCLUSIONS

Being a potentially treatable cause of ischemic stroke, celiac disease must be considered as a potential etiology of stroke of unknown cause, particularly in young patients, and even without gastrointestinal manifestations.
