Vaccination in patients with inflammatory bowel disease-Asian perspectives: the results of a multinational web-based survey in the 8th Asian Organization for Crohn's and Colitis meeting.

ABSTRACT:

Background/aims

Long-term immunosuppressive therapies used to treat inflammatory bowel disease (IBD) are associated with an increased risk of infections, many of which can be prevented by vaccination. We assessed physicians' current approaches and clinical practices regarding vaccinations for IBD patients in different Asian countries/regions.

Methods

An internet-based survey was conducted among members of the Asian Organization for Crohn's and Colitis from September 2020 to November 2020. The questionnaire consisted of 2 parts covering general opinion on the relevance of vaccinations and clinical practice of vaccination.

Results

Overall, 384 Asian medical doctors responded to the survey. The majority of respondents considered it very (57.6%) or sufficiently (39.6%) important to perform vaccinations as recommended by the guidelines. About half of the Asian physicians (52.6%) were usually or always performing vaccinations. The influenza vaccine was the most frequently recommended vaccine for IBD patients. Half of the respondents (51.3%) did not recommend hepatitis A vaccine, especially in China (61.6%) and Japan (93.6%). The diphtheria, tetanus, and pertussis vaccine were never (35.2%) or rarely (29.4%) recommended.

Conclusions

The findings of this survey indicated similarities among countries/regions in terms of the current approaches and practices regarding vaccination of IBD patients; however, there are some differences that might reflect each country's domestic vaccination guidelines and health insurance particularly with certain vaccines in some countries/regions. Although Asian physicians largely recommend vaccination, more awareness among doctors and Asian consensus regarding differences in IBD vaccination among countries/regions may be required.

Project description:Background/aimsVedolizumab is indicated for moderately-to-severely active ulcerative colitis (UC) and Crohn's disease (CD). Because multiple factors may result in different pharmacokinetics and clinical efficacies, understanding determinants of vedolizumab clearance may enhance dose and treatment strategies. The aim was to characterize vedolizumab pharmacokinetics in Asian and non-Asian UC and CD patients.MethodsPopulation pharmacokinetic analysis for repeated measures, using data from 5 studies, was conducted using nonlinear mixed-effects modeling. A Bayesian estimation approach in NONMEM 7.3 was utilized to leverage the predominantly sparse data available for this analysis with results from a prior population pharmacokinetic analysis of vedolizumab.ResultsVedolizumab pharmacokinetics were described by a 2-compartment model with parallel linear and nonlinear elimination. Using reference covariate values, linear elimination half life of vedolizumab was 24.7 days for anti-vedolizumab antibody (AVA)-negative patients and 18.1 days for AVA-positive patients; linear clearance (CLL) was 0.165 L/day for AVA-negative patients and 0.246 L/day for AVA-positive patients; central (Vc) and peripheral compartment volumes of distribution were 3.16 L and 1.84 L, respectively. Interindividual variabilities (percent coefficient of variation) were 30.8% for CLL and 19% for Vc; interoccasion variability on CLL was 20.3%; residual variance was 17.8%. For albumin, body weight and AVA, only extreme values were identified as potentially clinically important predictors of CLL. The effect of race (Asian/non-Asian) and diagnosis (UC/CD) on CLL was negligible and likely not of clinical importance.ConclusionsPharmacokinetic parameters were similar in Asian and non-Asian patients with moderately-to-severely active UC and CD. This analysis supports use of vedolizumab flat-fixed dosing in these patients. (Clinicaltrials.gov Identifiers: NCT00783718 (GEMINI 1); NCT00783692 (GEMINI 2).
