About
The investigators proposed study is the first of its kind. The investigators will measure measles, mumps, rubella, tetanus, diphtheria and pertussis antibodies in patients on the current IBD treatment modalities and compare the vaccine antibody concentrations and correlate them with time since immunization.
Full description
Tetanus and diphtheria have become rare diseases because of widespread immunization that began during World War II. The percentage of people who got pertussis (whooping cough) also went down after vaccination, but large outbreaks have occurred over the past decade. Measles, mumps, rubella (German measles) and varicella (chicken pox) are illnesses that resolve quickly, but which can cause other diseases to take hold or get worse. Routine vaccination can prevent infection and has been and recommended for use in the United States beginning in the 1960s and 1970s; and in 1995 for varicella. Today measles, mumps, and rubella are especially uncommon in the U.S. thanks to vaccination programs; and the percentage of people with varicella is going down. Despite widespread vaccination efforts, there have been recent outbreaks of measles and mumps in the U.S., in part because these diseases are still common in other parts of the world.
Inflammatory bowel disease (IBD) is a chronic inflammatory disorder of the gastrointestinal tract which includes Crohn's disease (CD) and ulcerative colitis (UC). Treatment options for IBD consist of immunosuppressive therapy, meaning that the drugs weaken the immune system, such as systemic corticosteroids, immunomodulators (thiopurines and methotrexate) and/or biologics, such as tumor necrosis factor alpha (TNF) agents or an integrin inhibitor (vedolizumab). Patients with IBD can achieve clinical remission and decrease the risk of complications with treatment; however, treatment can also increase the risk for infections because they weaken the immune system. Some of these infections are preventable with routine vaccination.
You are invited to take part in this research project to determine if people with IBD on different types of therapy have a lower amount of antibodies than healthy individuals. Antibodies are proteins used by the immune system to attack viruses like tetanus and measles. Antibodies can be introduced into the body through vaccines. The fewer antibodies there are, the harder it is for the antibodies to attack a virus, meaning that the person could get sick with a virus. This research project will help us figure out whether people with IBD have fewer antibodies than people without IBD. The investigators will also look at whether the type of treatment people take for IBD affects the amount of antibodies. T
This will tell us who is more likely to get sick from viruses, and why. The investigators will recruit 90 IBD patients under treatment for their IBD as well as 20 healthy controls for a total of 110 patients at the University of Wisconsin Hospital & Clinics.

- The patient must understand and voluntarily sign the informed consent document.
Exclusion Criteria
- Unconfirmed Td or Tdap vaccination status
- Patients in whom venipuncture are not feasible due to poor tolerability or lack of easy access.
