Weber–Christian disease, also known as relapsing fever, is a rare autoimmune disorder that affects the subcutaneous fat tissues. It is characterized by the formation of painful nodules in various parts of the body, especially the legs and the trunk, which can become inflamed and lead to fever, weight loss, and malaise.
The exact cause of Weber–Christian disease is unknown, but it is believed to be related to an autoimmune dysfunction in which the body’s immune system mistakenly attacks its own fat tissues. This can lead to inflammation, pain, and destruction of the affected tissues.
There are several different types of Weber–Christian disease, including:
- Acute febrile form: This is the most common form of Weber–Christian disease and is characterized by sudden onset of fever, weight loss, and malaise. Painful nodules may also develop in various parts of the body, especially the legs and trunk.
- Chronic form: This form of Weber–Christian disease is characterized by the gradual onset of symptoms and the development of nodules that may persist for years.
- Subacute form: This form of Weber–Christian disease is characterized by the gradual onset of symptoms and the development of nodules that may persist for several months.
- Recurrent form: This form of Weber–Christian disease is characterized by the repeated onset of symptoms and the development of nodules that may persist for several weeks at a time.
Regardless of the type, Weber–Christian disease can have a significant impact on a person’s quality of life, causing pain, discomfort, and functional limitations. In severe cases, the disease can also lead to disfigurement and scarring.
Causes

Symptoms
Here is a list of symptoms of Weber–Christian disease:
- Recurring fevers: One of the most prominent symptoms of Weber–Christian disease is recurring fevers. The fevers can be high and last for several days before subsiding, only to return again a few days later.
- Fatigue: Patients with Weber-Christian disease often experience significant fatigue and weakness, which can interfere with their daily activities.
- Painful muscle aches: Painful muscle aches, particularly in the legs, are a common symptom of Weber-Christian disease.
- Joint pain: Many patients with Weber-Christian disease experience joint pain, which can range from a mild ache to severe pain.
- Abdominal pain: Some individuals with Weber-Christian disease may experience abdominal pain, which can be caused by inflammation of the abdominal organs.
- Weight loss: Sudden and unintentional weight loss is a common symptom of Weber-Christian disease.
- Skin rashes: Skin rashes can develop as a result of the inflammation caused by Weber-Christian disease.
- Night sweats: Many patients with Weber-Christian disease experience night sweats, which can be a sign of the underlying inflammation.
- Nausea: Nausea is a common symptom of Weber-Christian disease and can be caused by inflammation in the abdominal organs.
- Vomiting: Vomiting can occur as a result of nausea or inflammation in the digestive system.
- Diarrhea: Some individuals with Weber-Christian disease may experience diarrhea, which can be caused by inflammation in the digestive system.
- Chest pain: Chest pain can occur in patients with Weber-Christian disease due to inflammation in the chest cavity.
- Shortness of breath: Some individuals with Weber-Christian disease may experience shortness of breath, which can be caused by inflammation in the chest cavity or lungs.
- Rapid heart rate: A rapid heart rate can occur as a result of the inflammation and fevers associated with Weber-Christian disease.
- Anemia: Anemia can develop as a result of the inflammation and tissue damage caused by Weber-Christian disease.
- Low white blood cell count: A low white blood cell count is a common laboratory finding in individuals with Weber-Christian disease.
- High erythrocyte sedimentation rate (ESR): A high erythrocyte sedimentation rate (ESR) is a laboratory test that can be elevated in patients with Weber-Christian disease due to the underlying inflammation.
- Elevated C-reactive protein (CRP): Elevated C-reactive protein (CRP) is a laboratory test that can be elevated in patients with Weber-Christian disease due to the underlying inflammation.
- Enlarged lymph nodes: Enlarged lymph nodes can occur as a result of the inflammation and tissue damage caused by Weber-Christian disease.
- Organ damage: In severe cases of Weber-Christian disease, organ damage can occur, particularly in the liver, spleen, and kidneys.
It is important to note that not all individuals with Weber-Christian disease will experience all of these symptoms.
Diagnosis
The following are 20 diagnostic tests that can be used to diagnose Weber-Christian disease:
- Physical Examination: A physical examination is the first step in diagnosing Weber-Christian disease. The doctor will examine the patient’s skin for any signs of swelling, redness, or tenderness.
- Blood Tests: Blood tests can help determine if the patient has an infection or an autoimmune disorder. Blood tests may include a complete blood count (CBC), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) test.
- Urine Tests: Urine tests can help determine if the patient has any underlying kidney problems that could be contributing to the symptoms of Weber-Christian disease.
- X-rays: X-rays can help the doctor determine if there is any damage to the bones or other tissues in the body.
- Magnetic Resonance Imaging (MRI): MRI is a non-invasive imaging test that uses a powerful magnetic field and radio waves to produce detailed images of the body. An MRI can help the doctor determine if there is any inflammation or damage to the tissues in the body.
- Computed Tomography (CT) Scan: CT scans are similar to X-rays, but they use X-rays and a computer to produce detailed images of the body. CT scans can help the doctor determine if there is any inflammation or damage to the tissues in the body.
- Biopsy: A biopsy is a procedure in which a small sample of tissue is taken from the affected area and examined under a microscope. This can help the doctor determine if the patient has Weber-Christian disease or another type of autoimmune disorder.
- Antinuclear Antibody (ANA) Test: The ANA test is used to detect antibodies in the blood that are directed against the body’s own tissues. This test can help determine if the patient has an autoimmune disorder.
- Rheumatoid Factor (RF) Test: The RF test is used to detect antibodies in the blood that are directed against the body’s own tissues. This test can help determine if the patient has an autoimmune disorder, such as rheumatoid arthritis.
- Erythrocyte Sedimentation Rate (ESR) Test: The ESR test measures the rate at which red blood cells settle to the bottom of a test tube. An elevated ESR can indicate inflammation in the body.
- C-reactive Protein (CRP) Test: The CRP test measures the level of C-reactive protein in the blood. C-reactive protein is a substance produced by the liver in response to inflammation in the body.
- HLA-B27 Antigen Test: The HLA-B27 antigen test is used to determine if the patient has a genetic predisposition to developing autoimmune disorders.
- Antineutrophil Cytoplasmic Antibody (ANCA) Test: The ANCA test is used to detect antibodies in the blood that are directed against the body’s own tissues. This test can help determine if the patient has an autoimmune disorder, such as Wegener’s granulomatosis.
- Antiphospholipid Antibody (APA) Test: The APA test is used to
Treatment
Treatments that have been used to manage Weber–Christian disease:
