title: [Two children with suspected primary vasculitis of mesenteric vessels--a case report].
abstract: We reported 2 children with suspected primary vasculitis of mesenteric vessels. Both children were admitted to our hospital with the complaints of abdominal pain, bloody stool or diarrhea. Laboratory examination simultaneously revealed leukocytosis with dominant neutrophils, positive CRP, and hypoalbuminemia. Although prothrombin time and activated partial thromboplastin time were within normal limits, the increased levels of FDP-E, D-dimer, and von Willebrand factor activity were observed, which suggested the endothelial cell activation and the coagulation/fibrinolysis system activation. Abdominal echography and CT scanning demonstrated the edematous thickening of intestinal or colon walls probably due to the vasculitic permeability changes of mesenteric artery. During the disease courses, skin rash, bleeding tendency, arthritis and proteinuria were not observed, and no autoantibodies including anti-nuclear antibody, anti-DNA antibody, and myeloperoxidase-antineutrophil cytoplasmic antibody, were detected. Taken together, we suspected these children as restricted vasculitis of mesenteric vessels. Intravenous prednisolone was administrated, and the clinical and laboratory abnormalities recovered completely within 2 weeks. Thus, we suggested that the leukocyte counts, CRP, and the determination of von Willebrand factor and coagulation/fibrinolysis study accompanied with X-ray, echography, and CT scanning will be useful for the early diagnosis of vasculitis before the pathologic and irreversible vascular damage are demonstrated.
