Infectious esophagitis

Definition

Esophagitis is a term for any inflammation, irritation, or swelling of the esophagus. This is the tube that carries food and liquids from the mouth to the stomach.

Infectious esophagitis is an infection of the esophagus from viruses, bacteria, fungi, or yeast. This most often occurs in people with a weak immune system.

Alternative Names

Infection - esophagus; Esophageal infection

Causes

Infectious esophagitis is rare. It often occurs in people with weak immune systems. People who have strong immune systems don't usually develop the infection.

Common causes of a weakened immune system include:

HIV/AIDS
Chemotherapy
Diabetes
Leukemia or lymphoma
Medicines that suppress the immune system, such as ones given after organ or bone marrow transplant
Other conditions that suppress or weaken your immune system

Organisms (germs) that cause esophagitis include fungi, yeast, and viruses. Common organisms include:

Candida albicans and other Candida species
Cytomegalovirus (CMV)
Herpes simplex virus (HSV)
Human papillomavirus (HPV)
Tuberculosis bacteria (Mycobacterium tuberculosis) -- not common

Symptoms

Symptoms of infectious esophagitis include:

Difficulty swallowing
Painful swallowing
Fever and chills
Yeast infection of the tongue and lining of the mouth (oral thrush)
Sores in the mouth or back of the throat (with herpes or CMV)

Exams and Tests

Your health care provider will ask about your symptoms and examine your mouth and throat. Tests may include:

Blood and urine tests for CMV
Culture of cells from the esophagus for herpes or CMV
Mouth or throat swab culture for candida

You may need to have an upper endoscopy exam. This is a test to examine the lining of the esophagus.

Treatment

Most often, medicines can control the infection. The type of medicine given will depend on the cause of the infection.

Antiviral medicines can treat a herpes infection. Common antiviral medicines for a herpes infection are:

Acyclovir
Famciclovir
Valacyclovir

Antifungal medicines can treat candida infection. Common antifungal medicines are:

Fluconazole (taken by mouth)
Caspofungin (given by injection)
Amphotericin (given by injection)

Antiviral medicines can treat CMV infection. Ganciclovir or foscarnet are given through a vein (intravenously). In some cases, a medicine called valganciclovir, which is taken by mouth, can be used for CMV infection.

Some people may also need pain medicine.

Ask your provider for special diet recommendations. For example, there may be foods you need to avoid eating as your esophagitis heals.

Many people need other long-term medicines to suppress the virus or fungus and to prevent the infection from coming back.

Outlook (Prognosis)

In people with a healthy immune system, esophagitis often goes away on its own. People with a weak immune system may take longer to get better.

Possible Complications

Health problems that may result from infectious esophagitis include:

Holes in your esophagus (perforations)
Infection at other sites
Recurrent infection

When to Contact a Medical Professional

Contact your provider if you have any condition that can cause reduced immune response and you develop symptoms of infectious esophagitis.

Prevention

If you have a weak immune system, try to avoid contact with people who have an infection with any of the organisms mentioned above.
