ABSTRACT
Objective To explore the function of infliximab in inducing remission in Crohn's disease and the effect of the inducing remission were followed up. Methods Ten patients with Crohn's disease received a infliximab, 5-aminosalicylic acid (5-ASA) and Azathioprine (AZA) therapy for inducing and maintenance remission. Crohn' s disease activity index (CDAI), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), alanine aminotransferase (ALT), apartate aminotransferase, (AST), total bilirubin (TBil), conjugated bilirubin, (CB), creatinine (Scr) were evaluated at week 0, 10, 22 and 50. Simple endoscopic score for Crohn's disease (SES-CD) were evaluated at week 0, 10 and 50. Adverse reactions were also evaluated. Results At week 10, all patients achieved remission. The indicators of CDAI, CRP, ESR and SES-CD were significantly declined than those at week 0 (P＜0.01). The follow-up was terminated in one patient due to the relapse at week 30. At week 50, the indicators of CDAI, CRP, ESR and SES-CD in six patients a little bit increased compared with those at week 10, but no statistic significant (P=0. 2001、0. 0600、0. 1328、0. 4230 respectively), but significantly declined compared with those at week 0 (P =0.0005、0.0087、0.0054、0. 0163 respectively). No severe adverse reaction was observed in all patients.Conclusions Infliximab showed an exact efficacy in inducing remission in Crohn's disease. And 5-ASA and AZA were effective for maintenance remission in part of the patients after infliximab induced remission.
ABSTRACT
Objective To compare the difference of protein and lipid metabolism between patients with inflammatory bowel disease and healthy controls,and to investigate the association of these changes with disease activity and location of the lessions.Methods The retrospective cohort study was carried out.The data of protein and lipid metabolisms collected from 195 patients with ulcerative colitis,76patients with Crohn's disease and 97 healthy controls during 1995 to 2007 were analyzed.Disease activity were evaluated using simple clinieal colitis activity index and simple index of Crohn's disease activity.The erythrocyte sedimentation rate(ESR)and C-reactive protein(CRP)were measured.Results Serum levels of ESR in patients with ulcerative colitis were negatively linear correlated with serum levels of albumin/globulin ratio(β=-0.521,P＜0.01)and positively linear correlated with serum levels of α2globulin(β=0.319,P＜0.01).Serum levels of globulin in patients with Crohn's disease were positively linear correlated with serum levels of ESR(β=0.558,P＜0.01)and CRP(β=0.424,P=0.01).In ulcerative colitis,serum levels of albumin/globulin ratio,albumin and total cholesterol were significantly higher in patients with proctosigmoiditis than those in patients with lesions at other locus(P=0.003,0.005,0.038,respectively).In Crohn's disease,serum level of globulin was significantly higher in patients with lesions only at colon than that in patients with lesions only at small bowel(P=0.029).Conclusions Serum levels of albumin/globulin ratio and α2-globulin can be predictors of inflammatory activity in patients with ulcerative colitis.The increasing serum globulin may predict the progression of disease activity in patients with Crohn's disease.The nutritional deficiency is more critical in patiens with small bowel involvement than those with colon involvement.
