OverviewOverview

Lupus is a chronic autoimmune disease in which the body's immune system becomes hyperactive and mistakenly attacks normal, healthy tissue. This results in inflammation, swelling, and damage to joints, skin, kidneys, blood, the heart, and lungs. Lupus can affect various parts of the body and its symptoms range from mild to life-threatening.

Onset of lupus can be triggered by various factors, including infections, certain drugs, or even sunlight. Lupus is known for its unpredictable nature, with periods of flares and remissions. Understanding this condition is critical for managing its impact on daily life and long-term health.

Risk Factors

Certain risk factors make individuals more likely to develop lupus, including genetics and environmental influences. Family history plays a significant role, and having a relative with lupus or other autoimmune diseases increases the risk. Gender is another key factor, as lupus predominantly affects women, particularly those of childbearing age.

Environmental triggers such as ultraviolet light, infections, and stress can also exacerbate the condition. Hormonal factors might contribute to the susceptibility to lupus, explaining why it is more common in women. Certain medications have also been identified as potential risk enhancers.

Causes

The exact cause of lupus remains unknown, but it is believed to be the result of a combination of genetic, hormonal, environmental, and immune system factors. Genes can create a predisposition to the disease, which is then triggered by external factors like infections or certain medications.

Autoimmunity plays a central role in lupus, where the body's immune system incorrectly identifies its own tissues as foreign invaders and produces antibodies to attack them. This chronic state of misguided immune response leads to inflammation and tissue damage.

Signs and Symptoms

Lupus can manifest with a wide array of signs and symptoms, and these can vary significantly from person to person. Commonly affected areas include the skin, joints, kidneys, and lungs. One of the hallmark signs of lupus is a butterfly-shaped rash across the cheeks and nose.

Other symptoms can include fatigue, joint pain and swelling, fever, chest pain, shortness of breath, and dry eyes. Due to its multisystem involvement, lupus may also cause cognitive impairment and mental health issues.

Diagnosis and Tests

Diagnosing lupus is often a challenging process due to its diverse and overlapping symptoms with other diseases. Physicians rely on a combination of medical history, physical examination, and various tests to confirm lupus. Blood tests such as antinuclear antibody (ANA) and anti-double-stranded DNA (anti-dsDNA) are commonly used.

Other diagnostic tools include urinalysis, imaging tests like X-rays, and biopsy of affected tissues. It is often a process of exclusion, ruling out other potential causes before arriving at a lupus diagnosis. Consultation with specialists such as rheumatologists is frequently necessary.

Treatments

While there is no cure for lupus, treatment aims to control symptoms and minimize flare-ups. Medications such as nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, antimalarial drugs, and immunosuppressants are commonly prescribed. The choice of treatment depends on the severity and specific manifestations of the disease.

In recent years, the FDA approved biologic therapies including belimumab and anifrolumab-fnia for patients with lupus nephritis and systemic lupus erythematosus, respectively. In 2021, voclosporin became the first oral treatment for adults with active lupus nephritis. Calcineurin inhibitors including ciclosporin are also shown to benefit patients with lupus.

Besides medications, lifestyle modifications are crucial. Regular exercise, a balanced diet, and adequate rest are essential for overall health. Preventative measures like avoiding sunlight and managing stress also play a significant role in disease management.

Tips and Extra Resources

Living with lupus requires a proactive approach to health maintenance and symptom management. Patients should closely monitor their symptoms and communicate effectively with their healthcare team. Regular medical checkups are vital to adjust treatment plans as needed.

Support groups and counseling can provide emotional and psychological support, helping individuals cope with the chronic nature of the disease. Reliable resources for further information and support include organizations like the Lupus Foundation of America and the American College of Rheumatology.
