Lupus Profundus

Lupus profundus, also known as subcutaneous lupus erythematosus (SLE), is a rare and severe form of lupus, a chronic autoimmune disease that affects various systems in the body. It is characterized by deep skin involvement, leading to the formation of thick, red, scaly plaques and nodules. In this article, we will discuss the definition, causes, symptoms, diagnosis, and treatment of lupus profundus.

Definition: Lupus profundus is a subtype of lupus erythematosus that specifically affects the subcutaneous tissues, which are the tissues located below the skin. It is a chronic autoimmune disorder that causes skin lesions that are thick, red, and scaly.

Causes

The exact cause of lupus profundus is unknown, but several factors are believed to play a role in its development. Below is a list of possible causes of lupus profundus:

  1. Genetics: Some people may have a genetic predisposition to developing lupus profundus.
  2. Environmental triggers: Exposure to certain environmental factors, such as UV light, may trigger the onset of lupus profundus.
  3. Immune system dysfunction: Lupus profundus is believed to be an autoimmune disorder, where the immune system mistakenly attacks healthy cells and tissues.
  4. Hormonal imbalances: Hormonal imbalances, such as those seen in women during pregnancy or menopause, may increase the risk of developing lupus profundus.
  5. Infections: Certain infections, such as Epstein-Barr virus, may trigger the onset of lupus profundus.
  6. Medications: Certain medications, such as hydralazine, procainamide, and isoniazid, may increase the risk of developing lupus profundus.
  7. Chemical exposure: Exposure to certain chemicals, such as pesticides, may increase the risk of developing lupus profundus.
  8. Stress: Chronic stress has been linked to the development of autoimmune disorders, including lupus profundus.
  9. Sun exposure: Excessive sun exposure may trigger the onset of lupus profundus, particularly in individuals who are prone to the condition.
  10. Smoking: Smoking has been linked to an increased risk of developing lupus profundus.
  11. Obesity: Obesity has been linked to an increased risk of developing lupus profundus.
  12. Vitamin D deficiency: Low levels of vitamin D have been linked to an increased risk of developing lupus profundus.
  13. Alcohol consumption: Excessive alcohol consumption has been linked to an increased risk of developing lupus profundus.
  14. Nutrient deficiencies: Nutrient deficiencies, such as those seen in individuals with poor diets, may increase the risk of developing lupus profundus.
  15. Trauma: Physical trauma, such as a major injury or surgery, may trigger the onset of lupus profundus.
  16. Age: The incidence of lupus profundus increases with age, with the majority of cases occurring in individuals over the age of 50.
  17. Family history: Individuals with a family history of lupus profundus may be at an increased risk of developing the condition.
  18. Race: Lupus profundus is more common in individuals of African descent.
  19. Sex: Women are more likely to develop lupus profundus than men.
  20. Chronic diseases: Individuals with chronic diseases, such as diabetes and heart disease, may be at an increased risk of developing lupus profundus.

It is important to note that not all individuals with lupus profundus will have the same triggers or underlying causes. In many cases, the cause of lupus profundus is unknown.

Diagnosis

Common tests and diagnoses for lupus profundus:

  1. Physical examination: A doctor will examine the skin lesions and other physical symptoms to determine the presence of lupus profundus.
  2. Blood tests: Blood tests can help diagnose lupus profundus by checking for markers such as antibodies, inflammation, and kidney function.
  3. ANA test: ANA (antinuclear antibody) tests are used to detect the presence of antibodies in the blood that are associated with autoimmune disorders like lupus.
  4. ENA test: ENA (extractable nuclear antigen) tests are used to determine the specific type of autoimmune disorder, such as lupus, that is present.
  5. Complement levels: Complement levels can help diagnose lupus profundus by measuring the levels of complement proteins in the blood, which are involved in the immune response.
  6. C3 and C4 levels: C3 and C4 levels can help diagnose lupus profundus by measuring the levels of these proteins in the blood, which are involved in the complement system.
  7. Anti-dsDNA test: Anti-dsDNA (double-stranded DNA) tests are used to detect antibodies that target DNA in people with lupus.
  8. Anti-Ro/SSA test: Anti-Ro/SSA tests are used to detect antibodies that target specific proteins in people with lupus.
  9. Anti-La/SSB test: Anti-La/SSB tests are used to detect antibodies that target specific proteins in people with lupus.
  10. Rheumatoid factor test: Rheumatoid factor tests are used to detect the presence of antibodies in the blood that are associated with autoimmune disorders like rheumatoid arthritis.
  11. CCP test: CCP (cyclic citrullinated peptide) tests are used to detect antibodies in the blood that are associated with autoimmune disorders like rheumatoid arthritis.
  12. HLA-B27 test: HLA-B27 tests are used to determine if a person has a genetic marker that is associated with an increased risk of developing autoimmune disorders like lupus.
  13. Skin biopsy: A skin biopsy involves removing a small sample of skin for examination under a microscope to confirm the presence of lupus profundus.
  14. Dermatopathology: Dermatopathology is a type of skin biopsy that involves examining the skin under a microscope to diagnose skin disorders like lupus profundus.
