Increased Mortality Rates With Prolonged Corticosteroid Therapy When Compared With Antitumor Necrosis Factor-?-Directed Therapy for Inflammatory Bowel Disease.

ABSTRACT:

Objectives

Crohn's disease (CD) and ulcerative colitis (UC) are inflammatory bowel diseases (IBD) that compromise quality of life and may increase mortality. This study compared the mortality risk with prolonged corticosteroid use vs. antitumor necrosis factor-? (anti-TNF) drugs in IBD.

Methods

A retrospective cohort study was conducted among Medicaid and Medicare beneficiaries from 2001 to 2013 with IBD prescribed either >3,000?mg of prednisone or equivalent within a 12-month period or new initiation of anti-TNF therapy, each treated as time-updating exposures. The primary outcome was all-cause mortality. Secondary outcomes included common causes of death. Marginal structural models were used to determine odds ratios (ORs) and 95% confidence intervals (CIs) for anti-TNF use relative to corticosteroids.

Results

Among patients with CD, 7,694 entered the cohort as prolonged corticosteroid users and 1,879 as new anti-TNF users. Among patients with UC, 3,224 and 459 entered the cohort as prolonged CS users and new anti-TNF users, respectively. The risk of death was statistically significantly lower in patients treated with anti-TNF therapy for CD (21.4 vs. 30.1 per 1,000 person-years, OR 0.78, 0.65-0.93) but not for UC (23.0 vs. 30.9 per 1,000 person-years, OR 0.87, 0.63-1.22). Among the CD cohort, anti-TNF therapy was also associated with lower rates of major adverse cardiovascular events (OR 0.68, 0.55-0.85) and hip fracture (OR 0.54, 0.34-0.83).

Conclusions

Compared with prolonged corticosteroid exposure, anti-TNF drug use was associated with reduced mortality in patients with CD that may be explained by lower rates of major adverse cardiovascular events and hip fracture.

Project description:Introduction: Tumor necrosis factor antagonists (anti-TNF) therapies are used for the management of moderate to severe inflammatory bowel disease (IBD). Anti-TNF combination therapy, with immunomodulators, has been shown to reduce immunogenicity, especially for infliximab, improve treatment success rate and patient outcomes. We evaluated factors associated with gastroenterologists adherence to anti-TNF combination therapy. Methods: A retrospective cohort study was performed to evaluate the adherence of gastroenterologists (n = 14), at an inflammatory bowel disease center, to anti-TNF combination therapy. Records of patients who received Infliximab (n = 137) or adalimumab (n = 152) were obtained and their ordering physicians' data was analyzed. Gastroenterologists were divided into six groups according to their age and interest in IBD. The baseline characteristics of their patients were also obtained. Results: The proportion of patients on combination therapy in the young gastroenterologists group was higher than those in the senior gastroenterologists group for both infliximab (83.2 vs. 55.6%, respectively, P < 0.001) and adalimumab (59 vs. 30.8%, respectively, P < 0.001). Gastroenterologists with interest in inflammatory bowel disease (IBD interest group) had also more proportion of patients on adalimumab combination therapy compared to gastroenterologists with no interest in IBD (non-IBD interest group) (61.7 vs. 35.2%, respectively, P < 0.001). Gastroenterologists who were both young and have interest in IBD had more proportion of patients on combination therapy than those who were senior or had no interest in IBD for both infliximab (89.4 vs. 63.4%, respectively, P < 0.001) and adalimumab (75.9 vs. 33%, P < 0.001). The IBD interest group was also requesting more antidrug antibody level tests than those in the non-IBD interest group (41.4 vs. 12.3 tests, respectively, P < 0.001). Conclusion: Young gastroenterologists are more likely to prescribe anti-TNF infliximab and adalimumab combination therapy than senior gastroenterologists. In addition, gastroenterologists with IBD interest are more likely to prescribe adalimumab combination therapy than gastroenterologists with no IBD interest. Moreover, young gastroenterologists who have interest in IBD are more likely to prescribe both infliximab and adalimumab combination therapy than senior gastroenterologists or those with no IBD interest. In addition, gastroenterologists with IBD interest requested more anti-TNF serum drug concentrations and antidrug antibody level tests than those with no IBD interest.
