Inflammatory bowel disease (IBD) is a group of chronic inflammatory disorders of the gastrointestinal tract. A recent national survey from the CDC estimates that the prevalence of IBD in the United States (US) is nearly 3.1 million cases. IBD is often associated with debilitating symptoms, hospitalizations, decreased quality of life, frequent procedures and/or surgery. Treatment options include immunosuppressive therapies, such as corticosteroids, immunomodulators (thiopurines and methotrexate) and anti-tumor necrosis factor alpha (TNF) agents. Although they are effective in achieving clinical remission and decrease the risk of complications, they also increase the risk for serious infections, including herpes zoster (HZ).
The primary goal is to study those patients with IBD who are thought to be at the highest risk for HZ reactivation by evaluating cell mediated immunity (CMI) to VZV.

Non-immunosuppressed IBD patients
24 IBD patients on mesalamine therapy or no IBD therapy
12 IBD patients on azathioprine at least 2.0mg/kg or 6MP 1.0mg/kg
12 IBD patients on maintenance therapy infliximab (at least 8 every 8 weeks), golilumab (at least monthly), adalilumab (at least every 2 weeks), or certolizumab (at least monthly)
12 IBD patients on anti-TNF therapy as described in group along with either 15mg of methotrexate or azathioprine at least 1.0mg/kg or 6MP 0.5mg/kg
The control group with consist of 12 individuals who meet the following inclusion and exclusion criteria.
Individuals will be obtained from patients without an IBD diagnosis, chronic liver disease, celiac disease or other chronic health condition coming to Digestive Health Center for endoscopic procedures or clinic visits.
12 IBD patients on vedolizumab maintenance therapy every 4-8 weeks
Prednisone and Anti-TNF therapy
12 IBD patients on Anti-TNF maintenance therapy as combination or mono therapy along with at least 10mg of prednisone
- Immune response by T cell, cell mediated immunity, to varicella zoster virus in patients with inflammatory bowel disease. [ Time Frame: Day 1 ]ELISPOT is an enzyme-linked assay for detecting and enumerating cytokine-producing lymphocytes. ELISPOT can detect cytokine-producing cells in as few as 1 in 300,000 cells. ELISPOT is the standard for measuring varicella cell mediated immunity.
