Proctitis is usually caused by underlying medical conditions. These include: sexually transmitted infections (STIs) inflammatory bowel disease (IBD), such as Crohn's disease or ulcerative colitis
Proctitis is inflammation of the lining of the rectum. The rectum is a muscular tube that's connected to the end of your colon. Stool passes through the rectum on its way out of the body. Several diseases and conditions can cause inflammation of the rectal lining. They include Inflammatory bowel disease. Infections Radiation therapy for cancer Antibiotics. Diversion proctitis Food protein-induced proctitis. Eosinophilic proctitis Risk factors Risk factors for proctitis include: Unsafe sex. Practices that increase your risk of a sexually transmitted infection (STI) can increase your risk of proctitis. Your risk of contracting an STI increases if you have multiple sex partners, don't use condoms and have sex with a partner who has an STI. Inflammatory bowel diseases. Having an inflammatory bowel disease (Crohn's disease or ulcerative colitis) increases your risk of proctitis. Radiation therapy for cancer. Radiation therapy directed at or near your rectum (such as for rectal, ovarian or prostate cancer) increases your risk of proctitis. Anti-Saccharomyces cerevisiae antibodies (ASCA) are immune proteins that are frequently present in people who have inflammatory bowel disease (IBD). This test detects ASCA in the blood. The test for anti-Saccharomyces cerevisiae antibodies (ASCA) is used to help distinguish between Crohn disease (CD) and ulcerative colitis (UC), the two most common types of inflammatory bowel disease (IBD). Testing usually includes detecting two different classes of ASCA in the blood, IgG and IgA. A positive ASCA result is not diagnostic of CD, UC, or of an IBD, but it does make it more likely that a person with symptoms has an IBD. Results of ASCA testing are often interpreted in conjunction with the results of pANCA testing: If ASCA is positive and pANCA is negative, then it is likely that the person has CD. If ASCA is negative and pANCA is positive, then it is likely that the person has UC. A negative result for ASCA and pANCA does necessarily rule out IBD. A person who is negative may still have CD, UC, or another IBD. The presence of multiple antibodies (ASCA, anti-CBir1, anti-Omp C) may indicate the likelihood of a more aggressive disease, but negative results do not rule out aggressive disease.
