You may be undergoing cancer treatment. Or you may have a weakened immune system. At times like these, all sorts of health problems can arise. Today we are going to talk about a condition like this, especially related to the intestines, which is a bit serious, but can be controlled very well if detected early . This is what we call Typhlitis.
What is Typhlitis? Simply put...
Simply put, Typhlitis is a severe inflammation of our digestive system, that is, the intestines. This inflammation can lead to bacterial and fungal infections. Although this is a rare condition, it is more likely to occur in people who are receiving intensive chemotherapy, especially for certain types of blood cancer (for example, leukemia, lymphoma, multiple myeloma).
Think of our intestines as a long tube. Typhlitis can affect different parts of this intestine:
- This condition is most commonly seen in the cecum, a part of the large intestine.
- In addition, the ascending colon
- And the ileum, which is part of the small intestine, can also be affected.
Doctors sometimes use other names for this condition, such as neutropenic enterocolitis , typhlenteritis, or ileocecal syndrome. But they all refer to the same condition.
Who is at risk of Typhlitis?
This risk is not only for those undergoing cancer treatment, but also for several other people.
- People with HIV/AIDS can develop typhoid fever.
- Also, people who take immunosuppressants , for example, those who have had a stem cell/bone marrow transplant, or those who have had another organ transplant, are at risk of developing this condition.
Although this condition can be life-threatening , it is important to remember that it can be cured if symptoms are identified early and treatment begins quickly.
What are the symptoms of Typhlitis?
Typhlitis symptoms can sometimes feel like a bad stomach ache or a stomach bug. But they are more than just a simple stomach ache. Common symptoms include:
- Severe abdominal pain and cramps
- Distended/ swollen belly
- Diarrhea
- Fever
- Nausea and vomiting
Imagine someone named Nimali, who is undergoing chemotherapy for leukemia. Suddenly, she develops severe stomach pain, fever, and vomiting. She thinks that she may have eaten food poisoning. But if these symptoms do not subside after two or three days, it is very important to seek medical advice immediately . Because it could be Typhlitis.
Why does Typhlitis occur? What are the causes?
Researchers believe that typhlitis is caused by a combination of factors. The three main factors are:
1. Mucositis: This is the inflammation of the mucus membranes that line the inside of our large intestine and small intestine. Just like ulcers can form inside our mouth, ulcers and inflammation can also occur inside the intestine. This can especially happen as a side effect of treatments like chemotherapy.
2. Neutropenia: Neutropenia is a decrease in a type of white blood cell called neutrophils. These neutrophils are like important soldiers in our immune system . They are the ones who fight infections. Chemotherapy can cause a decrease in these neutrophils.
3. Weak immune system: Cancer treatments (like chemotherapy) and infections like HIV/AIDS can weaken our entire immune system.
Now let's see how this happens. First, mucositis damages the lining of the intestines. This allows bad bacteria and fungi to easily enter the intestines . At that time, if our body has low neutrophils (neutropenia) and the immune system is weak, the body is unable to fight off these invaders. The result is severe infections and complications that can be life-threatening. Examples:
- Gastrointestinal bleeding
- Gastrointestinal perforation
- Sepsis and septic shock - This is a severe infection that spreads throughout the body.
What are the main germs that cause Typhlitis?
Research has found that many different types of bacteria and fungi (which we call pathogens) can cause typhlitis. Some of the most common types of bacteria are:
- *Clostridium septicum*
- *Enterococci*
- *Gram-negative enterobacteria*
- *Pseudomonas aeruginosa*
- *Staphylococcus aureus*
- *Streptococcus*
Also, the most common types of fungi are:
- *Aspergillus*
- *Candida*
This may seem a bit complicated, but doctors know about it so you don't have to worry too much about it. The important thing is to understand that these types of germs are what make the problem worse.
How do doctors diagnose Typhlitis?
If you have any of the symptoms listed above, your doctor will first do a physical exam. Then they will ask you questions about your medical history. For example, they will ask if you have been treated for cancer, have had a stem cell transplant or organ transplant, and if you have HIV/AIDS. In addition, blood tests and special imaging tests may be done.
Blood tests
The doctor may order blood tests like these:
- Complete Blood Count (CBC): This can check things like neutrophil levels.
- Kidney function tests
- Liver function tests
- Prothrombin time test: See blood clotting.
Imaging tests
The most common test used for this is a CT scan (Computed Tomography - CT scan) . This scan can see if the walls of your colon are thicker than normal. This thickening of the walls of the colon is caused by inflammation.
How is Typhlitis treated?
There is no one-size-fits-all treatment for typhoid fever. Everyone's situation is different. But in general, the main goal of treatment is to control the infection and support your immune system . You may need a combination of different treatments. Here are some of the most common treatments:
- Antibiotics: Control bacterial infections. Antifungals may also be given.
- Blood transfusion: If you have low blood pressure.
- Decompressive laparotomy: A surgery performed to reduce pressure inside the abdomen if it is too high.
- Granulocyte Colony-Stimulating Factor (G-CSF): This is a vaccine given to increase neutrophil levels.
- Intravenous fluids (IV fluids): Prevent dehydration and provide the body with the fluids it needs.
- Total Parenteral Nutrition (TPN): This involves giving the digestive system a break, allowing it to heal, and then providing the necessary nutrients directly through a vein.
If you are being treated for cancer, your oncologist may make changes to your cancer treatment until you recover from typhlitis. If typhlitis causes a bowel perforation, surgery may be necessary.
What is the mortality rate? Should we be afraid?
Typhoid fever is a serious, potentially fatal condition . At one time, almost everyone who contracted typhoid fever died from complications such as sepsis. But that is no longer the case . With early detection and prompt treatment, more people are now recovering from typhoid fever. A recent study showed that more than 60% of people with fungal infections caused by typhoid fever recovered after treatment. So, it is important to stay hopeful .
When should I see my doctor?
The symptoms of Typhlitis may seem like other, more common problems with your gut. But as mentioned earlier, the symptoms of Typhlitis are more than just an upset stomach. If you have any of these symptoms, see your doctor without hesitation :
- Fever
- Nausea and vomiting
- Severe stomach cramps and limping
Having these symptoms doesn't mean you have typhoid fever again, but it's always a good idea to talk to your doctor if you notice any changes in your body.
What questions should I ask my doctor?
You may have Typhlitis because of a condition that affects your immune system, or because you are undergoing cancer treatment. Here are some questions you can ask your doctor:
- Can you tell me exactly why I developed Typhlitis?
- Is it possible for this to happen again?
- Will I have to stop cancer treatment?
Treating a serious illness like cancer or HIV/AIDS can feel like climbing a mountain. As you navigate challenges like side effects from treatment, the goal of recovery is what keeps you going. When a new, serious health problem like typhlitis arises, it can feel like another mountain to climb. But remember, there are treatments that can cure typhlitis.
Even so, you may feel discouraged. You may wonder how you will overcome this new obstacle and get back on track with your recovery. Your medical team understands how much of a setback a new diagnosis can feel like. They will answer your questions about typhlitis treatment and how it will affect your recovery.
Finally, things to remember (Take-Home Message)
Typhlitis is a scary condition, but it can be cured if detected early and treated properly.
- It is especially important for those undergoing chemotherapy, those with HIV/AIDS, and those taking medications that suppress the immune system to be aware of this.
- If you experience symptoms such as severe stomach pain, fever, and vomiting, do not assume it is just a simple stomach ache and see a doctor immediately.
- Follow the doctor's instructions exactly. Do not stop treatment halfway.
- Stay strong. Your medical team will help you.
I hope this information is useful to you. Stay healthy!
