Tropheyma whipplei (Whipple’s Disease)

Tropheyma whipplei, Whipple’s disease is a rare bacterial infection that primarily affects the gastrointestinal system. The condition is caused by the bacterium Tropheryma whipplei. It was first described by Dr. George Hoyt Whipple in 1907.

Whipple’s disease can affect various parts of the body, including the small intestine, joints, heart, and central nervous system. However, it is most commonly associated with malabsorption in the small intestine, leading to weight loss, diarrhea, and nutritional deficiencies.


An infection with the bacterium Tropheryma whipplei causes Whipple’s disease. The exact mode of transmission of the bacterium is not fully understood, and it is not clear why some people develop the infection while others do not. Tropheryma whipplei is commonly found in the environment, and exposure to the bacterium is considered relatively common.

Despite the widespread presence of Tropheryma whipplei, Whipple’s disease itself is rare. It is believed that only a small percentage of individuals exposed to the bacterium develop the infection. Some factors may predispose certain individuals to Whipple’s disease, but these factors are not well-defined.

It’s important to note that Whipple’s disease is not considered a contagious condition, meaning it is not easily transmitted from person to person. The mode of transmission and the factors leading to the development of the disease are still areas of ongoing research.

Symptoms of Whipple’s disease?

Whipple’s disease can present with a variety of symptoms, and they can vary from person to person. The symptoms often develop gradually and may be nonspecific, resembling those of other gastrointestinal disorders. Some of the common symptoms of Whipple’s disease include:

  1. Gastrointestinal symptoms:
    • Diarrhea
    • Abdominal pain or cramping
    • Bloating and flatulence
    • Weight loss due to malabsorption of nutrients
  2. Joint symptoms:
    • Joint pain and swelling
    • Arthritis, especially affecting the large joints
  3. Fever:
    • A low-grade fever is a common symptom.
  4. Neurological symptoms:
    • In more advanced cases, the central nervous system may be affected, leading to symptoms such as confusion, memory loss, and difficulty with coordination.
  5. Other symptoms:
    • Fatigue
    • Anemia (due to malabsorption of iron)
    • Lymphadenopathy (enlarged lymph nodes)
    • Skin pigmentation changes

Whipple’s disease can affect various organs and systems in the body, so the symptoms can be diverse. Neurological involvement is a serious complication that may occur in some cases, leading to cognitive and motor impairments. Because the symptoms of Whipple’s disease can overlap with those of other conditions, a thorough medical evaluation is necessary for an accurate diagnosis. Diagnostic tests may include blood tests, imaging studies, and a biopsy of the small intestine to identify the characteristic foamy macrophages containing the bacterium Tropheryma whipplei.

Is Whipple disease contagious?

Whipple’s disease itself is not considered contagious. It is caused by the bacterium Tropheryma whipplei, which is commonly found in the environment. Despite the widespread presence of this bacterium, only a small percentage of individuals exposed to it develop Whipple’s disease.

The mode of transmission of Tropheryma whipplei is not fully understood, and factors that contribute to the development of Whipple’s disease in some individuals while others remain unaffected are still being studied. It’s important to note that casual person-to-person transmission of Whipple’s disease is not a known risk, and the condition is not typically spread from one person to another.

Whipple’s disease is more likely to occur in individuals who may have a genetic predisposition or other factors that make them susceptible to the infection. The bacterium is thought to be acquired from the environment, possibly through the consumption of contaminated food or water, but the exact mechanisms are not well-defined.

How is Whipple’s disease diagnosed?

The diagnosis of Whipple’s disease involves a combination of clinical evaluation, laboratory tests, imaging studies, and, in many cases, a small intestine biopsy. Here are the steps typically involved in the diagnostic process:

  1. Clinical Evaluation:
    • A healthcare professional will conduct a thorough medical history and physical examination. They will inquire about symptoms, including gastrointestinal issues, joint pain, fever, and neurological symptoms.
  2. Blood Tests:
    • Blood tests may be performed to assess for signs of inflammation, anemia, and nutritional deficiencies. Specific tests may also be done to look for antibodies against Tropheryma whipplei.
  3. Stool Examination:
    • Stool samples may be analyzed for signs of malabsorption, and to detect the presence of Tropheryma whipplei DNA.
  4. Imaging Studies:
    • Imaging tests, such as endoscopy, may be conducted to visualize the gastrointestinal tract and identify abnormalities. Radiological studies, such as CT scans or MRI, may also be used to assess organ involvement.
  5. Small Intestine Biopsy:
    • A definitive diagnosis of Whipple’s disease often requires a biopsy of the small intestine. This involves obtaining a tissue sample (usually from the duodenum) for examination under a microscope. The characteristic finding in Whipple’s disease is the presence of foamy macrophages containing periodic acid-Schiff (PAS)-positive granules, indicating the presence of Tropheryma whipplei.

The small intestine biopsy is often considered the gold standard for diagnosing Whipple’s disease. In some cases, other tissues, such as lymph nodes or the synovium (lining of the joints), may also be biopsied if there are symptoms suggesting involvement of these areas.

What are the complications of Whipple’s disease?

Whipple’s disease, if left untreated or not promptly treated, can lead to various complications affecting different organ systems. Some of the potential complications include:

  1. Malabsorption and Nutritional Deficiencies:
    • The primary manifestation of Whipple’s disease is malabsorption in the small intestine, leading to deficiencies in nutrients such as proteins, fats, vitamins, and minerals. This can result in weight loss, weakness, and other symptoms related to nutritional deficiencies.
  2. Arthritis and Joint Damage:
    • Joint involvement is common in Whipple’s disease, and if not addressed, it can lead to persistent joint pain, swelling, and damage. The large joints are often affected.
  3. Cardiac Involvement:
    • In some cases, the heart may be affected, leading to complications such as valve damage or heart failure.
  4. Neurological Complications:
    • Whipple’s disease can involve the central nervous system, leading to neurological symptoms such as confusion, memory loss, and difficulty with coordination. In severe cases, it can result in cognitive impairment and other neurological deficits.
  5. Eye Involvement:
    • Ocular manifestations, including uveitis (inflammation of the middle layer of the eye) and other eye symptoms, may occur.
  6. Systemic Effects:
    • The infection can spread to various organs and tissues, causing a range of systemic symptoms and complications.

How can I prevent Whipple’s disease?

Preventing Whipple’s disease involves minimizing exposure to the bacterium Tropheryma whipplei, although the exact mode of transmissionBlastomyces is not fully understood. Since the bacterium is commonly found in the environment, it may be challenging to eliminate the risk of exposure. However, here are some general recommendations:

  1. Maintain Good Hygiene:
    • Practice good hygiene, including regular handwashing with soap and water, especially after using the restroom and before handling food. This can help reduce the risk of ingesting or coming into contact with the bacterium.
  2. Food Safety:
    • Follow proper food safety practices, including thorough cooking of meat, proper storage of food, and avoiding consumption of raw or undercooked foods, particularly in areas with a higher risk of contamination.
  3. Water Safety:
    • Be cautious about the safety of drinking water, especially when traveling to areas with potential waterborne infections. Consider drinking bottled or treated water, and avoid consuming water from potentially contaminated sources.
  4. Avoid High-Risk Environments:
    • Individuals with compromised immune systems may be at a higher risk of developing Whipple’s disease. In such cases, it may be advisable to avoid environments where exposure to the bacterium is more likely, such as areas with poor sanitation.
  5. Prompt Medical Attention:
    • If you develop symptoms suggestive of Whipple’s disease, seek prompt medical attention. Early diagnosis and treatment are crucial for a favorable outcome, and delays in seeking medical care can increase the risk of complications.

Whipple’s disease is rare, and specific preventive measures are not well-established due to the limited understanding of the transmission of Tropheryma whipplei. If you have concerns about your risk or if you are in a high-risk group, such as individuals with immune system disorders, it’s advisable to consult with a healthcare professional for personalized advice.

Remember that maintaining overall good hygiene practices, practicing safe food and water habits, and being vigilant about your health are general measures that can contribute to reducing the risk of various infections, including Whipple’s disease.
