        Japanese physicians` attitudes towards enteral nutrition treatment for pediatric patients with Crohn`s disease: a questionnaire survey

        ( Takashi Ishige ),( Takeshi Tomomasa ),( Hitoshi Tajiri ),( Atsushi Yoden ) 대한장연구학회 2017 Intestinal Research Vol.15 No.3

        Background/Aims: Enteral nutrition (EN) is recommended for the treatment of pediatric Crohn`s disease (CD) in Japan. However, the indications and treatment protocols for EN vary among hospitals. In the present study, we aimed to determine how EN was administered to pediatric patients and whether physicians followed treatment guidelines in their practices. Methods: Two types of questionnaires were administered to 32 physicians who were involved in the treatment of pediatric CD. The consensus questionnaire evaluated the physicians` attitudes towards EN, whereas the efficacy questionnaire collected data on patients with CD, aged <17 years, who had undergone induction therapy between 2006 and 2011. Results: A total of 23 physicians responded to the questionnaires. The results of the consensus questionnaire indicated that 82% and 59% of study participants recommended EN treatment for all newly diagnosed pediatric patients with CD and all relapsed patients, respectively. Exclusive EN (EEN) and elemental formula were recommended by 84% and 85% of physicians, respectively. The efficacy questionnaire revealed that 57 of the 58 patients received EN. Elemental formula was used in 39 of 40 patients who were treated with EEN. Of these 40 patients, 27 were treated with EEN alone; of these, 22 (81%) achieved remission without any other treatment. The mean duration of EEN was 15.9 days. Conclusions: EN is widely recommended by physicians treating pediatric CD in Japan. In contrast to Western countries, clinicians used elemental formula more often and with a shorter EEN treatment duration. (Intest Res 2017;15:345-351)

        Whipple disease mimicking inflammatory bowel disease

        ( Maiko Tatsuki ),( Takashi Ishige ),( Yoshiko Igarashi ),( Reiko Hatori ),( Akira Hokama ),( Junko Hirato ),( Aleixo Muise ),( Takumi Takizawa ),( Hirokazu Arakawa ) 대한장연구학회 2021 Intestinal Research Vol.19 No.1

        Whipple disease is a systemic chronic infection caused by Tropheryma whipplei. Although chronic diarrhea is a common gastrointestinal symptom, diagnosis is often difficult because there are no specific endoscopic findings, and the pathogen is not detectable by stool culture. We present a female patient with Whipple disease who developed chronic bloody diarrhea and growth retardation at the age of 4 years. Colonoscopy showed a mildly edematous terminal ileum and marked erythema without vascular patterns throughout the sigmoid colon and rectum. Subsequently, a primary diagnosis of ulcerative colitis was made. Histopathological analysis of the terminal ileum showed the presence of foamy macrophages filled with periodic acid-Schiff-positive particles. Polymerase chain reaction using DNA from a terminal ileum biopsy sample amplified a fragment of 16S rRNA from T. whipplei. Antibiotic treatment relieved the patient’s symptoms. There was no evidence of immunodeficiency in the present case. Since Whipple disease worsens after anti-tumor necrosis factor inhibitor therapy, considering this infection in the differential diagnosis may be important in patients with inflammatory bowel disease, especially before initiation of immunotherapy.

        Phenotypic characteristics of pediatric inflammatory bowel disease in Japan: results from a multicenter registry

        ( Katsuhiro Arai ),( Reiko Kunisaki ),( Fumihiko Kakuta ),( Shin-ichiro Hagiwara ),( Takatsugu Murakoshi ),( Tadahiro Yanagi ),( Toshiaki Shimizu ),( Sawako Kato ),( Takashi Ishige ),( Tomoki Aomatsu 대한장연구학회 2020 Intestinal Research Vol.18 No.4

        Background/Aims: There are few published registry studies from Asia on pediatric inflammatory bowel disease (IBD). Registry network data enable comparisons among ethnic groups. This study examined the characteristics of IBD in Japanese children and compared them with those in European children. Methods: This was a cross-sectional multicenter registry study of newly diagnosed Japanese pediatric IBD patients. The Paris classification was used to categorize IBD features, and results were compared with published EUROKIDS data. Results: A total of 265 pediatric IBD patients were initially registered, with 22 later excluded for having incomplete demographic data. For the analysis, 91 Crohn’s disease (CD), 146 ulcerative colitis (UC), and 6 IBD-unclassified cases were eligible. For age at diagnosis, 20.9% of CD, 21.9% of UC, and 83.3% of IBD-unclassified cases were diagnosed before age 10 years. For CD location, 18.7%, 13.2%, 64.8%, 47.3%, and 20.9% were classified as involving L1 (ileocecum), L2 (colon), L3 (ileocolon), L4a (esophagus/stomach/duodenum), and L4b (jejunum/proximal ileum), respectively. For UC extent, 76% were classified as E4 (pancolitis). For CD behavior, B1 (non-stricturing/non-penetrating), B2 (stricturing), B3 (penetrating), and B2B3 were seen in 83.5%, 11.0%, 3.3%, and 2.2%, respectively. A comparison between Japanese and European children showed less L2 involvement (13.2% vs. 27.3%, P<0.01) but more L4a (47.3% vs. 29.6%, P<0.01) and L3 (64.8% vs. 52.7%, P<0.05) involvement in Japanese CD children. Pediatric perianal CD was more prevalent in Japanese children (34.1% vs. 9.7%, P<0.01). Conclusions: Upper gastrointestinal and perianal CD lesions are more common in Japanese children than in European children. (Intest Res 2020;18:412-420)
