Background: The purpose of the study was to collect data on granulocyte-monocyte adsorptive apheresis (GMA) for the treatment of corticosteroid-dependent (SD) or corticosteroid-resistant (SR) inflammatory bowel disease (IBD) in children from 3 Nordic countries to evaluate its efficacy and safety and to assess practical issues. Methods: Retrospective data on 37 children treated with GMA were collected. In all, 22 children had ulcerative colitis (UC), 13 Crohn's disease (CD), and 2 had indeterminate colitis (IC). Their mean age was 13.2 years, range 5–17 years, and mean duration of disease was 2.4 years, range 1 month to 6 years. Indication for treatment in the UC group was SD in 11 cases, SR in 6 cases, and other reasons in 5 cases. The corresponding numbers in the CD group were SD in 8 cases, SR in 2 cases, and other reasons in 3 cases. In the IC group, 1 had SD and 1 was refractory to steroids, azathioprine, and infliximab. Efficacy was evaluated by severity indices: the Pediatric Ulcerative Colitis Activity Index (PUCAI) and the Pediatric Crohn's Disease Activity Index (PCDAI) and tapering of corticosteroids. Results: PUCAI and PCDAI decreased significantly in both groups after 3 months (P = 0.0007, P = 0.025). The dosage of corticosteroid was significantly reduced in the UC group by the end of GMA (P = 0.004) and this response continued after 3 months. Relapse was seen in 2 patients with UC and 3 patients with CD after 3 months follow-up. Conclusions: GMA seems to be an effective and safe treatment in 81% of the SD or SR pediatric IBD patients, especially in those with UC. (Inflamm Bowel Dis 2009)

Aim To describe the response pattern to enteral nutrition (EN) in paediatric patients with moderately to severely active Crohn's disease (CD). Material and methods A previously described method for assessment of response pattern to various treatments for CD was used. Patients who received EN during the 10-year period 1995–2005 were prospectively registered. Patient data, clinical outcome, time to relapse and subsequent need for treatment were extracted from the files. Four weeks treatment with polymeric ready-to-use liquid formula was given. The clinical outcome was assessed by pattern recognition of the disease course 30 days (immediate response) and 90 days (long-term response) after start of EN. Results Thirty-one patients (17/14 M/F), median age 14 years (range 7.5 –19.8 years), received 46 courses of EN. Thirty-seven courses (80%) were completed. Immediate response: twenty-five courses (67%) led to complete response (CR), 8 (22%) to partial response (PR) and in 4 courses (11%) no response (NR) was achieved. Long-term response: 21 courses (64%) led to prolonged response (PRO), defined as either maintenance of complete response (CR) or partial response (PR), while 12 courses (36%) were followed by loss of response (LR). The median time to relapse was 8.3 months (range 0.5–39 months). Conclusion We found our model of response pattern to be a useful instrument for the description of results obtained during EN in children with CD.

Infection with Helicobacter pylori in childhood may be the initiation of a lifelong coexistence between microorganisms and epithelial cells resulting in chronic inflammation. The adhesion pattern of H. pylori found in antral biopsies from a group of H. pylori-infected children with recurrent abdominal pain was compared with a group of H. pylori-infected adults suffering from dyspepsia, in an attempt to reveal differences in the type of adhesion.The histology of antrum biopsies and the ultrastructure of adherent H. pylori in biopsies from 26 children (median age, 10.1 years) were compared with organisms in biopsies from 19 adults (median age, 54.4 years).More than 1000 adherent H. pylori were studied and divided into four types of adhesion: 1) contact to microvilli; 2) connection to the plasma membrane via filamentous material; 3) adhesive pedestal formation; and 4) abutting or making a depression in the plasma membrane. Contact to microvilli was significantly higher (69% versus 39%; P = 0.002) in children compared with adults and comprised two-thirds of all adherent organisms in children. The more intimate adhesion types as abutting or adhesive pedestals dominated in adults.These results indicate a change in contact types between H. pylori and gastric epithelial cells in adults compared with children and this may be a natural development in the lifelong infection of humans.

We report on our experience with routine abdominal ultrasonography in 120 children (aged 3–15 years) with recurrent abdominal pain, in order to determine the diagnostic value of this investigation. Eight children (7%) revealed sonographic abnormalities: gallbladder stone (n = 2), splenomegaly (n = 1) and urogenital abnormalities (n = 5). The recurrent abdominal pain could be explained by these findings in only two (may be three) cases. Conclusion The diagnostic value of abdominal ultra‐sonography in unselected children with recurrent abdominal pain is low. However, the direct visualization of the abdominal structures as being normal may be helpful to the parents and the child in their understanding and acceptance of the benign nature of recurrent abdominal pain.
