About

Inflammatory bowel disease (IBD) is a chronic inflammatory state of the gastrointestinal tract affecting 1.6-3.1 million people in the United States. Patients with IBD are treated with immunosuppressants that increase their risk of herpes zoster (HZ), also known as shingles.

Those with IBD have a two-fold increased risk for HZ compared to age matched controls. Because most IBD patients are treated with systemic immunosuppressants, which are an independent risk factor for HZ, the live attenuated HZ vaccine was not recommended. However, the release of the new inactivated HZ vaccine, Shingrix (GlaxoSmithKline), presents new opportunities for preventive care.

Full description

The purpose of this study is to determine the immunogenicity of the herpes zoster subunit vaccine in inflammatory bowel disease patients on vedolizumab compared to those on anti-tumor necrosis factor (TNF) monotherapy.

The study will evaluate humoral and cell mediated immunity in patients with IBD on vedolizumab who receive the two-dose herpes zoster vaccine. The investigators will evaluate short term, one month after second vaccination dose and sustained immunogenicity at 6 and 12 months post vaccination.

The central hypothesis of this proposal is that IBD patients on vedolizumab should be able to mount a normal vaccine response comparable to those on anti-TNF monotherapy who might benefit from a third dose of the subunit vaccine as has been evaluated in HIV and transplant populations. The hypothesis is that IBD patients on vedolizumab will be able to mount a superior response to those on anti-TNF therapy. A recent study showed that hepatitis B vaccine immunogenicity was not affected by vedolizumab.

The study population will include adult patients aged 18 to 70 with IBD (diagnosed by standard clinical, radiographic, endoscopic, and histopathologic criteria) receiving care at University of Wisconsin Hospital and Clinics. There is no randomization or use of placebo in this study. Two study groups will be established:

• Group A: Patients with IBD on anti-TNF monotherapy
• Group B: Patients with IBD on vedolizumab monotherapy

Eligible patients with IBD will be recruited from the University of Wisconsin Hospital and Clinics.

Enrollment: 33 patients

Sex: All

Ages: 18 to 70 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Patient is between the ages of 18-70 years, inclusive.

3. Patient has a history of ulcerative colitis (UC) or Crohn's disease diagnosed by standard clinical, radiographic, endoscopic, and histopathologic criteria.
4. Patient is receiving one of the following treatments for their IBD Group A: Anti-TNF monotherapy (adalimumab, certolizumab, golimumab, infliximab) Group B: Vedolizumab monotherapy
5. Patient has been on stable treatment for IBD for at least three months.

Exclusion criteria

1. Previous receipt of any HZ vaccine
2. Allergy to zoster vaccine or a component of it
3. Other underlying chronic medical condition that could affect immunogenicity to vaccines (rheumatoid arthritis, etc.)
4. History of herpes zoster or post herpetic neuralgia within the past year.

8. Patient has received polyclonal immunoglobulin therapy or blood products within the last year.
9. Patient is pregnant per self-reporting or older than age 70 years
10. Unable to provide appropriate informed consent due to being illiterate or impairment in decision-making capacity.
