Ulcerative colitis (UC) may cause crypt abscesses to form. Crypt abscesses occur when inflammatory cells accumulate in crypts, or pouches, inside the gastrointestinal system.
Ulcerative colitis is a form of inflammatory bowel disease (IBD). It occurs due to the immune system having an
UC can cause a person to experience diarrhea, blood in their stool, and abdominal pain.
This article will explore what crypt abscesses are and the type of crypt abscesses that may occur. It will also explore how crypt abscesses may occur in UC and other causes of crypt abscesses and their treatments.
The epithelial layer is the layer of cells that lines the organs, such as the large intestine and small intestine in the gastrointestinal (GI) tract. This layer folds back on itself to form a cavity or pouch, known as the crypt, which
Crypt abscesses occur when there is a buildup of inflammatory cells within the crypts. The inflammatory cell accumulation can harm the surrounding cells and prevent the crypts from secreting substances and functioning effectively.
Small crypt abscesses may resolve less frequently on their own, while other types may require medication or surgical intervention.
Types of crypt abscesses
Two types of crypt abscesses may occur: neutrophilic and apoptotic.
Neutrophilic crypt abscesses contain white blood cells — neutrophils — that help the body fight infection. Apoptotic abscesses contain apoptotic cells that get rid of unneeded or abnormal cells, which is also known as programmed cell death.
In UC, inflammation normally begins in the rectum and progresses to the colon. Crypt abscesses form as a response to active inflammation. The abscesses are commonly neutrophilic in UC.
The destruction of the crypts can also cause the loss of the mucosal architecture, which leads to the colon becoming more rigid and short. It may take on a “lead-pipe” appearance.
When inflammation occurs with IBD, the crypts
- macrophages to remove dead and dying cells
- neutrophils that attack bacteria
- dendritic cells to produce immune responses against pathogens
- natural killer T lymphocytes to destroy compromised cells
A doctor may diagnose a crypt abscess in a person with UC by taking a sample of the affected tissues, such as a part of the colon. This is known as a biopsy. A doctor will look at this sample under a microscope to see if there have been any structural changes to the cells.
In UC, a doctor may be able to see the
Treatment for crypt abscesses may depend on how severe the person’s UC is.
Mesalamine will lower the number of inflammatory cells by infiltrating the crypts. Untreated, these cells lead to abscesses.
Crypt abscesses can also occur as a result of other conditions or medications. Some of these are listed below.
Radiation for colon cancer
One of the side effects of this treatment type is that tissues within the body may
The reactive oxygen species may also damage the crypts of the GI tract and may also result in inflammatory cells infiltrating the crypts and causing crypt abscesses.
Other conditions, infections, or medications may cause a crypt abscess. If one of these is the reason, a doctor will recommend a suitable line of treatment, such as:
Treatment may involve the use of anti-inflammatory medication such as corticosteroids and sulphasalazine. More severe cases may require surgery. However, medical professionals may consider this a last resort due to the high rate of complications postsurgery.
Both infections may cause
Treatment for H. pylori may
Some medications may cause crypt abscesses. For example, mycophenolate mofetil (MMF) is an immunosuppressant drug that treats autoimmune diseases, and doctors use it after organ and bone marrow transplants.
However, MMF also causes gastrointestinal symptoms in
A doctor may discontinue MMF in a person experiencing gastrointestinal symptoms. If symptoms do not improve, they may also prescribe a steroid such as prednisolone or infliximab.
Crypt abscesses occur when inflammatory cells build up in the crypts of the GI tract. Crypt abscesses can occur in UC due to inflammation in the colon and rectum.
A doctor may diagnose crypt abscesses in UC by taking a sample of the affected area and observing under a microscope for crypt changes and the presence of inflammatory cells.
Other causes of crypt abscesses include Crohn’s disease, radiation, medications, and infections, some of which have appropriate treatments recommended by doctors.
