Abstract

BACKGROUND: Norovirus gastroenteritis is commonly an acute infection that lasts 2-3 days, but in immunocompromised patients norovirus can cause a chronic gastroenteritis lasting for years. Norovirus replicates in the gastrointestinal tract, but the pathway of viral clearance is not yet known. Promising results of enterally administered immunoglobulin in the treatment of chronic norovirus gastroenteritis in immunocompromised patients have previously been published.

CASE PRESENTATION: We report two individuals with common variable immunodeficiency and chronic debilitating norovirus gastroenteritis. Both patients were treated with enterally administered immunoglobulin via a duodenal feeding tube as other treatment modalities have been unsuccessful. The patients did not experience any immediate or long-term benefit of enterally administered immunoglobulin.

CONCLUSION: Despite previous case reports of successful treatment of chronic norovirus infection among immunocompromised patients with enterally administered immunoglobulin, these two patients experienced no benefit of the treatment. This demonstrates the need for further research in treatment of chronic norovirus infection in immunocompromised patients.
