In this study, nine patients were switched to azathioprine in the INF treatment group and 13 patients started on azathioprine in the cyclosporine treatment group. The rate of switching was 30% in the INF group compared to 37.1% in the cyclosporine group. Actual switching rate was calculated as patients who responded to treatment*proportion of patients who continued treatment*proportion of patients who switched (INF: 83.3% x 60% x . 60%=30% and cyclosporine: 71.4% x.
In a study (Taxonera 2011[4]) assessing patients with active UC, treatment with ADA after failure of other therapies, including INF, resulted in dose escalation from 40 mg every other week to 40 mg per week in 36.7% . In another study with ADA, 35% of patients experienced a dose escalation of ADA between weeks eight and week 16, from 40 mg every other week to 40 mg weekly, due to incomplete response (Afif 2009[1]).
Dose escalation and switching
This study reported an 81% increase in dose with ADA, indicating that out of a total of 181 semesters, there was an increase in dose in 104 semesters. In another study, 5.2% of patients (4 out of 76) had dose intensification (dose increase to INF 10 mg/kg in two patients and reduction of the infusion interval to six weekly in the remaining two patients) (Bhalme 2013 [8] ). Previous SNR to INF required dose escalation during ADA treatment more often than patients who had previously responded to INF (57% vs. 15%, p=0.01).
The cumulative probability of needing a dose escalation at 1 year was 60% in the previous SNRs to INF vs. Therefore, this study concluded that more than one-third of ADA-treated patients required dose escalation within a mean treatment duration of five months. Higher BMI and previous non-response to INF treatment at initiation of ADA treatment were predictive of the need for dose escalation during ADA treatment.
In the WELCOME trial (Sandborn switch was reported in 24.9% of patients in the CER every two weeks maintenance treatment group and 31.6% in the CER every four weeks maintenance treatment group. A study conducted in CD patients in Spain reported that 72% of patients required dose intensification (increasing ADA to a weekly dose), in order to maintain the clinical response (Cordero-Ruiz 2011[6]).
Surgery
Two variables were associated with a higher colectomy rate: the severity of the attack (8/19 vs. 0/11; p<0.02) and the absence of concomitant use of antimetabolites. However, patients who had recently undergone major surgery were less likely to be treated with INF; therefore, the number of procedures performed may have been low in the pre-INF group (Lindsay 2013[42]). EUA) at a time after their initial diagnosis and before the initiation of infliximab therapy, with 36.60%) of these having undergone more than one operation.
Adverse events
All other serious adverse events were graded as mild and were not significantly different in frequency between infliximab- and placebo-treated patients. In the CARE trial (Louis) patients experienced serious AEs, which could be attributed to the severity of disease of the patients involved (moderate to severe). Total withdrawals (due to lack of tolerance to treatment/any adverse event / serious adverse events related to inadequate response to treatment).

No statistically significant difference in costs was found between the planned and episodic groups after infliximab (£3339 vs.
Quality of life
In the CARE trial (Louis 2013[5]), mean baseline scores indicated severe impairment of productivity and poor quality of life. At week 20, 60% of infliximab-naive subjects and 47% of primary infliximab non-responders achieved clinically significant improvements (≥9 points) on the SIBDQ, and 51% and 43% of subjects who achieved minimal clinically important difference (improvement of ≥7 percentage points) for overall deterioration in work productivity (imputation of non-responders). At week 20, 64% of infliximab-naïve subjects and 55% of primary infliximab non-responders achieved a clinically significant improvement in total activity impairment.
At all scheduled visits, mean changes in the work productivity component (absence, attendance, and .TWPI) scores were represented statistically. According to the EuroQol-5D score, the majority of patients reported not having problems with mobility (96%), self-.
