Could JC virus be linked to chronic idiopathic intestinal pseudo-obstruction?
- 28 Downloads
JC virus is a member of the Polyomavirus family, infects humans worldwide, and 90% of the population carry antibodies to the virus by adult life. The initial infection is asymptomatic, but it may become persistent. JC virus DNA is frequently present in the upper and lower gastrointestinal tracts of healthy adults. Chronic idiopathic intestinal pseudo-obstruction, one of the most severe gastrointestinal motility disorders, is a condition characterized by a clinical picture mimicking small bowel occlusion with related symptoms and signs in the absence of demonstrable mechanical obstruction. Because of the known neuropathic capability of this virus, and its frequent presence in the gut, it has been proposed that JCV might be detectable in tissues of patients with chronic idiopathic intestinal pseudo-obstruction, and possibly be involved in the pathogenesis of this disease, because the virus may actively infect the enteroglial cells of the myenteric plexuses of the patients with chronic idiopathic intestinal pseudo-obstruction. We report two cases of upper idiopathic intestinal pseudo-obstruction associated with JCV infection.
