Collagenous sprue: don´t forget connective tissue in chronic diarrhea evaluation.

Collagenous sprue is a rare disease of the small bowel characterized by mucosal atrophy and excessive subepithelial collagen deposition. The etiology remains unclear and the diagnosis is based upon patient´s clinical picture and anatomopathological findings. Clinically, collagenous sprue is characterized by persistent diarrhoea, severe malabsorption, multiple nutrient deficiencies and progressive weight loss.

[Filgrastim in refractory Crohn's disease with an intra-abdominal abscess].

The application of recombinant human granulocyte colony-stimulating factor (filgrastim) seems to be a safe, well tolerated and potentially effective therapy for active Crohn's disease. We report the case of an adolescent boy with Crohn's disease and intra-abdominal abscess associated who had a significant response to treatment with recombinant human granulocyte colony-stimulating factor after all standard treatments had failed.
