Comparison of infliximab with adalimumab in biologic-naïve patients with Crohn's disease: a single-center 13-year experience

OBJECTIVE

Long-term comparison studies between infliximab (IFX) and adalimumab (ADA) with or without immunomodulator therapy are still needed in Crohn's disease (CD). In this study, we evaluated IFX and ADA for long-term clinical effectiveness and safety in CD patients who had not previously received a biologic treatment.

PATIENTS AND METHODS

The data of adult CD patients were collected retrospectively between December 2007 and February 2021. We compared CD-related hospitalization, CD-related abdominal surgery, steroid use, and serious infections.

RESULTS

Out of 224 CD patients, 101 started IFX first (median age: 38.12 years, 61.4% male), while 123 started ADA first (median age: 30.2 years, 64.2% male). The disease durations were 7.01 years and 6.91 years for IFX and ADA, respectively. There were no significant differences between the two groups with respect to age, gender, smoking, immunomodulator usage, and disease activity score at the onset of anti-TNF therapy (p>0.05). Overall, the median follow-up time was 2.36 and 1.86 years after starting anti-tumor necrosis factor-alpha (anti-TNF) therapy in the IFX and ADA groups, respectively. Steroid use (4.0% vs. 10.6%, p=0.109), hospitalization for CD (13.9% vs. 22.8%, p=0.127), abdominal surgery for CD (9.9% vs. 13.0%, p=0.608), and major infections (1.0% vs. 0.8%, p>0.999) did not differ significantly from one another. There were also no significant differences in the rates of these outcomes between concomitant immunomodulator therapy and monotherapy (p>0.05).

CONCLUSIONS

In this study, we observed no significant differences in the long-term effectiveness and safety of IFX and ADA in biologic-naïve patients with CD.

Similarities and Differences Between Gerontal and Young Patients with Acute Pancreatitis: Evaluation of Clinical Characteristics and Outcomes

Background:

Acute pancreatitis is an abrupt inflammatory disease of the exocrine pancreas and it can occur in different severities. It is becoming more common and more mortal in the gerontal population. The aim of our study was to explore the similarities and differences between young and gerontal patients with acute pancreatitis, with a special emphasis on patients over 80 years of age.

Methods:

Medical records of patients (n = 1150) with acute pancreatitis were analyzed retrospectively. Several scoring systems including Bedside index for severity in acute pancreatitis, Ranson’s score, Harmless acute pancreatitis score, Acute Physiology and Chronic Health Evaluation, Balthazar Grade, Glasgow score, and Japanese severity score were applied at admission. Patients were divided into 3 groups; group I, young group (n = 706), if they were aged <65 years; group II, older group (n = 338), if they were aged ≥65 years to <80 years; group III, octogenarian group (n = 106), if they were aged ≥ 0 years.

Results:

In total, 1150 patients with acute pancreatitis were analyzed. Octogenarian group (n = 42, 39.6%) showed a more severe acute pancreatitis compared to patients in group I (n = 15, 2.1%) and II (n = 50, 14.8%, P < .001). Complications were more common in patients in group III (P < .001). Mortality rate was higher in patients in group III (n = 53, 50%) compared to group I (n = 8, 1.1%) and group II (n = 53, 15.7%) (P < .001).

Conclusion:

Gerontal patients with acute pancreatitis tend to have more severe disease and systemic and local complications. Mortality rates were higher in older patients compared to younger patients.
