Can chemotherapy worsen my ulcerative colitis or infections?

Question

Hello doctor,

It is now six years that I have suffered from ulcerative colitis, which has always been under reasonable control by taking Azathioprine. Regrettably, I have been diagnosed with breast cancer and require urgent chemotherapy treatment.

The problem here is that my gastroenterologist is very worried about this situation since, besides being on Azathioprine, I will be under chemotherapy, meaning that my immune system will be extremely weakened and prone to infections as well as an attack of UC.

I am really confused and stressed by all these things; it seems impossible for me to cope with the task of protecting my colon from a flare while undergoing breast cancer treatment.

Kindly advise.

Hello,

Welcome to icliniq.com.

This situation can understandably feel overwhelming. Managing ulcerative colitis (UC) alongside treatment for breast cancer requires careful coordination, but gastroenterologists and oncologists frequently work together to manage such cases.

Azathioprine is one such immune-suppressing drug that is used in maintaining remission in ulcerative colitis. The drugs that are used in treating breast cancer through chemotherapy are also immunosuppressive drugs. Usage of these two types of drugs together increases the chances of infections and bone marrow suppression.

Because of this concern, many specialists consider temporarily pausing Azathioprine during chemotherapy, especially if ulcerative colitis has been stable for some time. In some cases, chemotherapy itself can suppress inflammatory activity in the bowel, which may help keep ulcerative colitis symptoms controlled during treatment.

Management of care is done using a multidisciplinary approach where both the oncologist and gastroenterologist will be involved. Blood counts as well as overall health condition are kept under close surveillance to enable adjustment of treatment when necessary.

Mesalamine (5-aminosalicylic acid) treatment can be recommended by doctors to avoid a flare during chemotherapy treatment. This drug is effective as an anti-inflammatory agent in the colon and produces few adverse effects on the immune system, which makes it relatively safe to use.

If symptoms of colitis begin to return, short courses of corticosteroids such as Prednisolone may sometimes be used under close medical supervision. The aim is to control intestinal inflammation without causing excessive suppression of the immune system.

Infection prevention becomes very critical during this time. Some of these precautions may include proper hygienic practices, avoiding people who have been infected, a proper nutritional diet, and informing your doctor about any signs or symptoms like fever and tiredness. Blood count testing as well as liver function testing is equally critical to treatment.

Although managing both conditions at the same time can be challenging, many patients successfully complete chemotherapy while keeping ulcerative colitis under control through careful medical monitoring and close collaboration between specialists.

I hope you are satisfied with my answer.

Thank you.
