Lupus Erythematosus Panniculitis

Lupus Erythematosus Panniculitis, also known as Lupus Panniculitis, is a rare subtype of cutaneous lupus erythematosus (CLE). Lupus is a chronic autoimmune disease in which the body’s immune system attacks healthy tissue and organs, leading to inflammation and damage.

Lupus Panniculitis is a type of CLE that primarily affects the subcutaneous fat layer, causing inflammation and fat necrosis. The term “panniculitis” refers to inflammation of the subcutaneous fat, and “erythematosus” refers to the characteristic red, scaly rash that is seen in lupus.

There are two main types of Lupus Panniculitis:

  1. Subacute Cutaneous Lupus Erythematosus (SCLE) SCLE is a subtype of CLE that primarily affects sun-exposed areas of the skin, such as the face, neck, arms, and legs. It typically presents as a rash with well-defined, scaly, annular plaques that may be red, pink, or brown. The rash may be itchy or painful, and it can be exacerbated by sun exposure.
  2. Lupus Profundus (LP) LP is a subtype of Lupus Panniculitis that affects deeper layers of the skin, including the subcutaneous fat. It is characterized by firm, nodular, or deep-seated lesions that may be red, purple, or blue. The lesions may be painful and can lead to scarring.

Both SCLE and LP are diagnosed based on a combination of clinical presentation, skin biopsy, and serologic testing. Serologic testing may include antinuclear antibody (ANA) testing, which can detect the presence of antibodies that target the body’s own cells and tissues.

Causes

Here are the potential causes for LEP:

  1. Genetics: There is evidence that LEP may have a genetic component, as the disease tends to run in families.
  2. Hormonal factors: Hormonal changes, such as those occurring during pregnancy, may trigger the onset of LEP.
  3. Environmental triggers: Exposure to ultraviolet (UV) light, sunburn, and other environmental factors may trigger LEP.
  4. Infections: Certain infections, such as those caused by viruses or bacteria, may trigger LEP.
  5. Medications: Certain medications, such as thiazide diuretics, beta-blockers, and angiotensin-converting enzyme (ACE) inhibitors, have been linked to the development of LEP.
  6. Autoimmune diseases: People with other autoimmune diseases, such as systemic lupus erythematosus (SLE) or rheumatoid arthritis, are more likely to develop LEP.
  7. Immune system dysfunction: A dysfunction in the immune system, such as an overactive immune response, may lead to LEP.
  8. Inflammation: Chronic inflammation, such as that seen in lupus, may contribute to the development of LEP.
  9. Vitamin D deficiency: A lack of vitamin D has been linked to the development of autoimmune diseases, including LEP.
  10. Stress: Stress has been linked to the onset and exacerbation of autoimmune diseases, including LEP.
  11. Smoking: Smoking has been linked to the development of autoimmune diseases, including LEP.
  12. Obesity: Obesity has been linked to the development of autoimmune diseases, including LEP.
  13. Chemical exposure: Exposure to certain chemicals, such as solvents and pesticides, may trigger the onset of LEP.
  14. Radiotherapy: Radiation therapy has been linked to the development of autoimmune diseases, including LEP.
  15. Infections: Certain infections, such as those caused by viruses or bacteria, may trigger LEP.
  16. Nutritional deficiencies: Nutritional deficiencies, such as a lack of essential fatty acids or vitamins, may contribute to the development of LEP.
  17. Age: LEP is more common in older individuals.
  18. Gender: Women are more likely to develop LEP than men.
  19. Ethnicity: LEP is more common in certain ethnic groups, including African Americans and Native Americans.
  20. Family history: A family history of autoimmune diseases, including LEP, may increase a person’s risk of developing the disease.

It’s important to note that LEP can develop in individuals without any known risk factors. The exact cause of LEP is not yet fully understood, and more research is needed to determine the underlying mechanisms of the disease.

Diagnosis

Diagnosis and tests that are commonly used to diagnose and manage lupus panniculitis:

  1. Clinical examination: A thorough physical examination is the first step in the diagnosis of lupus panniculitis. The dermatologist will look for characteristic skin changes such as subcutaneous nodules, rashes, and ulcers.
  2. Medical history: A comprehensive medical history is important in the evaluation of lupus panniculitis. The physician will ask about symptoms, family history, and past medical history to determine if there are any underlying conditions that could be contributing to the symptoms.
  3. Blood tests: Blood tests are a critical part of the diagnosis of lupus panniculitis. These tests can help to identify inflammation, autoimmune disorders, and infections. Some common blood tests include complete blood count (CBC), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) test.
  4. Antinuclear antibody (ANA) test: This test is used to detect the presence of antibodies in the blood that are directed against the body’s own cells and tissues. A positive ANA test is often indicative of lupus erythematosus.
  5. Anti-dsDNA test: This test measures the presence of antibodies to double-stranded DNA, which is often present in individuals with systemic lupus erythematosus.
  6. Antiphospholipid antibody test: This test measures the presence of antibodies that attack phospholipids, which are essential components of cell membranes. Antiphospholipid antibodies are commonly found in individuals with lupus erythematosus.
  7. Complement levels: Complement levels are proteins in the blood that help to fight infections. Low complement levels can indicate the presence of lupus erythematosus.
  8. Rheumatoid factor (RF) test: This test measures the presence of antibodies that attack healthy tissues and can cause inflammation in individuals with rheumatoid arthritis. A positive RF test can indicate the presence of lupus erythematosus.
  9. Skin biopsy: A skin biopsy is a procedure in which a small piece of skin is removed and examined under a microscope. This test can help to confirm the diagnosis of lupus panniculitis and identify any underlying skin conditions.
  10. Joint fluid analysis: In some cases, joint fluid analysis may be performed to help diagnose lupus panniculitis. This test involves removing a small sample of fluid from the affected joint and examining it for signs of inflammation and infection.
  11. X-rays: X-rays can be used to visualize the bones and joints and detect any signs of inflammation or damage.
  12. CT scan: A CT scan is a type of imaging test that uses X-rays and computer technology to produce detailed images of the body’s internal structures. CT scans can be used to detect any changes in the bones, joints, and soft tissues.
