Here's an overview of the causes, symptoms, diagnosis, treatment, and prevention of cutaneous lupus erythematosus (CLE).
Causes:
As a result of an abnormal immune response, the body's immune system mistakenly attacks healthy skin cells, causing inflammation and skin damage in the form of cutaneous lupus erythematosus. Although the exact cause of CLE is unknown, it is believed to involve a combination of genetic predisposition, environmental triggers, and dysregulation of the immune system.
Symptoms:
Depending on the subtype and severity of cutaneous lupus erythematosus, symptoms may include:
-
Rash: Red, scaly, or raised patches of skin on sun-exposed areas, such as the face, neck, scalp, or arms.
-
Exacerbation of skin symptoms due to increased sensitivity to sunlight.
-
The Malar Rash is a butterfly-shaped rash over the cheeks and nose bridge, typical of systemic lupus erythematosus (SLE), but also seen in some cases of chronic lupus erythematosus (CLE).
-
Thinning or hair loss (alopecia) in the scalp or other hair-bearing regions.
-
The development of ulcers, sores, or erosions on the lips, inside the mouth (oral ulcers), or on other mucosal surfaces.
Diagnosis:
A combination of clinical evaluation, skin biopsy, and laboratory tests are used to diagnose cutaneous lupus erythematosus. These methods include:
-
CLE Clinical Examination: Evaluation of skin lesions, rash patterns, and other associated symptoms.
-
A small sample of skin tissue is removed for microscopic examination to determine whether lupus-related features such as interface dermatitis, epidermal changes, and immune complexes are present.
-
Testing for autoantibodies commonly associated with lupus, such as antinuclear antibodies (ANA), anti-double-stranded DNA (anti-dsDNA), and anti-Smith antibodies (anti-Sm), can be done through blood tests.
Treatment:
The goal of treatment for cutaneous lupus erythematosus is to control symptoms, reduce inflammation, and prevent flare-ups. Treatment options include:
-
To reduce inflammation and alleviate symptoms, topical corticosteroids, calcineurin inhibitors, or other immunomodulatory agents can be applied directly to the skin.
-
In cases of widespread or refractory CLE, systemic medications such as antimalarials (e.g., hydroxychloroquine), oral corticosteroids, or immunosuppressive drugs may be prescribed.
-
It is possible to treat CLE lesions and improve skin symptoms with ultraviolet (UV) light therapy, including narrowband UVB or psoralen plus UVA (PUVA).
-
CLE sufferers can reduce disease activity and prevent flare-ups by avoiding sun exposure, wearing protective clothing and sunscreen, and quitting smoking.
Prevention:
In order to prevent cutaneous lupus erythematosus, it is important to minimize exposure to potential triggers and optimize overall health. Prevention strategies may include:
-
Using sun protection measures such as sunscreen, hats, and protective clothing to minimize sun exposure during peak UV radiation hours.
-
Identifying and avoiding potential triggers such as certain medications, infections, or environmental factors that may aggravate CLE symptoms.
-
Monitoring skin symptoms, disease activity, and response to treatment is essential for early detection and management of CLE flare-ups.
A chronic autoimmune condition characterized by skin inflammation and manifestations, cutaneous lupus erythematosus is a chronic autoimmune condition. For individuals with CLE to improve their quality of life, early diagnosis, appropriate treatment, and preventive measures are essential.
