RESUMO

BACKGROUND: Although Helicobacter pylori infection is closely associated with gastric cancer development, follow-up studies after H. pylori eradication are still scarce. AIM: To clarify the cancer preventive effect of H. pylori eradication, with special attention to differences in effect according to histology. METHODS: Patients who underwent H. pylori eradication therapy and were followed-up endoscopically for at least 1 year were analysed. The incidence of gastric cancer and factors associated with cancer development were investigated. RESULTS: A total of 1807 patients were enrolled. Six of 1519 H. pylori eradicated and five of 288 persistent subjects developed gastric cancer. Four of the eradicated subjects developed the intestinal type and two the diffuse type, while four of the persistent subjects developed the intestinal type and one the diffuse type. Kaplan-Meier analysis indicated a significantly lower incidence in eradicated patients than in persistent patients. The incidence of intestinal type was significantly lower than in eradicated patients, while the diffuse type could not be evaluated because of the low incidence. CONCLUSIONS: Helicobacter pylori-eradicated patients had a reduced incidence of gastric cancer compared with H. pylori-persistent patients, particularly the intestinal type, suggesting that H. pylori is strongly associated with intestinal-type gastric cancer.

RESUMO

Leukocytapheresis has recently been used to induce remission in patients with ulcerative colitis (UC) who fail to respond to corticosteroids. We could not find a report in the literature on leukocytapheresis for UC with gestational exacerbation. We have recently encountered this unique condition and report the details here. A 30-year-old Japanese woman with left-sided severe UC was corticosteroid-dependent and had recurrence of the active disease during tapering of corticosteroid. She declined any dose increase and the use of any immunosuppressive agent because she was in the 13th week of pregnancy. Then, concomitant leukocytapheresis was performed without increasing the corticosteroid dose. Recovery was rapid and dramatic. Mucous and bloody stool decreased after the first session, and she had remission 2 weeks later. She underwent a total of four sessions without complications. After 6 weeks, she was discharged from our hospital and underwent maintenance treatment as an outpatient with mesalazine and corticosteroid tapering. Subsequently, she gave birth to a healthy baby girl by an uncomplicated vaginal delivery while keeping the remitted stage of UC.
