BACKGROUND:: Infliximab (IFX) and adalimumab (ADA) are attractive treatment options in patients with inflammatory bowel disease (IBD) also during pregnancy but there is still limited data on the benefit/risk profile of IFX and ADA during pregnancy. METHODS:: This observational study assessed pregnancy outcomes in 212 women with IBD under antitumor necrosis factor alpha (TNF) treatment at our IBD unit. Pregnancy outcomes in 42 pregnancies with direct exposure to anti-TNF treatment (35 IFX, 7 ADA) were compared with that in 23 pregnancies prior to IBD diagnosis, 78 pregnancies before start of IFX, 53 pregnancies with indirect exposure to IFX, and 56 matched pregnancies in healthy women. RESULTS:: Thirty-two of the 42 pregnancies ended in live births with a median gestational age of 38 weeks (interquartile range [IQR] 37-39). There were seven premature deliveries, six children had low birth weight, and there was one stillbirth. One boy weighed 1640 g delivered at week 33, died at age of 13 days because of necrotizing enterocolitis. A total of eight abortions (one patient wish) occurred in seven women. Trisomy 18 was diagnosed in one fetus of a mother with CD at age 37 under ADA treatment (40 mg weekly) and pregnancy was terminated. Pregnancy outcomes after direct exposure to anti-TNF treatment were not different from those in pregnancies before anti-TNF treatment or with indirect exposure to anti-TNF treatment but outcomes were worse than in pregnancies before IBD diagnosis. CONCLUSIONS:: Direct exposure to anti-TNF treatment during pregnancy was not related to a higher incidence of adverse pregnancy outcomes than IBD overall. (Inflamm Bowel Dis 2011;).

OBJECTIVES: Scheduled maintenance therapy with infliximab decreases the risk of infusion reactions. Many centers have accelerated infusion times to 1 h in selected patients who tolerate 5 mg/kg infliximab infusions. The aim of this study was to compare the tolerability of 1-h and 2-h infliximab infusions in patients with inflammatory bowel disease (IBD) in a large single-center cohort. The primary end point was the incidence of infusion reactions in both groups. METHODS: A retrospective chart analysis of all IBD patients treated with infliximab was performed. Infusions in scheduled maintenance for at least 6 months from December 1994 until March 2009 were included. All patients were treated at the infusion unit or during hospitalization under standard operating procedures. Infusion parameters were prospectively recorded. From 2004, in patients tolerating at least four 2-h infusions, infusions were given over 1 h. RESULTS: As of March 2009, 953 patients with IBD (77.6% Crohn's disease, 22.4% ulcerative colitis) had been treated with infliximab. A total of 474 patients met the criteria of scheduled maintenance therapy. In total, 9,155 maintenance infusions were administered (4,307 over 1 h). No severe infusion reactions were documented. Mild acute reactions occurred in 0.6% (27/4,307) of the 1-h-infusion group and in 1.7% (80/4848) of the 2-h infusion group (P=0.0034). Delayed infusion reactions occurred in 0.2% of 1-h and 0.5% of 2-h infusion group patients (P=0.277). Loss of tolerability due to infusion reactions (1-h group 2.9% versus 2-h group 4.1%) was evenly distributed (P=0.34). None of the prespecified variables were predictive of infusion reactions in a multivariate analysis. CONCLUSIONS: In patients with IBD tolerating 2-h infusions of infliximab scheduled maintenance therapy, the infusion time can be shortened to 1 h with good tolerability. No severe reactions were observed and no predictors of infusion reactions were identified. [less ▲]Detailed reference viewed: 21 (9 ULg)

BACKGROUND & AIMS: Infliximab is an antibody against tumor necrosis factor-alpha that is used to treat patients with moderate to severe Crohn's disease (CD). C-reactive protein (CRP) is a marker used to identify and follow individuals with CD. We analyzed changes in levels of CRP in a large cohort of patients with CD undergoing treatment with infliximab. METHODS: Serial levels of CRP were analyzed in 718 CD patients. Blood was collected before each infusion; a total of 8845 CRP levels were available for analysis. The correlations between CRP levels and need for dose adjustment, outcomes, and mucosal healing (based on endoscopic analysis of 253 patients) were evaluated. Therapy adjustment was considered successful if therapy continued without need for change. Subgroup analysis was performed by using data from 268 patients who received 8 weeks of maintenance therapy. RESULTS: More patients with high baseline levels of CRP responded to infliximab than patients with normal levels (90.8% vs 82.6%; P = .014). Early normalization of CRP levels correlated with sustained long-term response (P < .001). CRP levels remained significantly higher among patients who lost their response to infliximab, compared with those with a sustained response (P = .001). At time of loss of response, CRP levels were significantly increased (median, 11.2 mg/L) and did not return to baseline levels (median, 18.2 mg/L; P = .039). CRP correlated with mucosal healing (P = .033). CONCLUSIONS: CRP is a good marker of disease activity in patients treated with infliximab. Increased levels of CRP indicate mucosal inflammation and a likelihood of clinical relapse. [less ▲]Detailed reference viewed: 12 (3 ULg)
