Lupus: Symptoms, Causes & Treatment

Synopsis

Lupus, or Systemic Lupus Erythematosus (SLE), is a chronic autoimmune disease in which the body’s immune system mistakenly attacks its own tissues and organs. This immune dysfunction can affect the skin, joints, kidneys, lungs, heart, and even the brain. The disease is often unpredictable, with periods of flare-ups followed by remission. While lupus can be challenging to diagnose due to its wide range of symptoms, early medical attention and ongoing care from an experienced rheumatologist can significantly improve quality of life.

Understanding Lupus

Lupus is primarily an autoimmune condition where the immune system, designed to fight infections, instead attacks healthy tissues. This leads to chronic inflammation, tissue damage, and a wide variety of symptoms that can affect multiple organ systems.

The most common type is Systemic Lupus Erythematosus (SLE), but there are other types too:

Cutaneous lupus – affects the skin, often leading to rashes and sensitivity to sunlight.
Drug-induced lupus – triggered by certain medications and usually resolves when the drug is discontinued.
Neonatal lupus – a rare condition affecting newborns due to maternal antibodies.

While lupus is more common in women, particularly during childbearing years, it can affect men and children as well.

Symptoms of Lupus

The symptoms of lupus can vary widely, making it difficult to diagnose. They often mimic other conditions, but some classic signs help identify the disease.

Early Signs and General Symptoms

Fatigue – persistent tiredness that doesn’t improve with rest.
Fever – unexplained low-grade fevers.
Joint pain and stiffness – often resembling arthritis.
Hair loss – patchy hair thinning due to inflammation.

Characteristic Symptoms

Butterfly rash: A red rash across the cheeks and nose, shaped like a butterfly, is one of the most recognizable signs of lupus.
Photosensitivity: Sensitivity to sunlight leading to rashes or skin flare-ups.
Mouth or nose ulcers: Painful sores that recur frequently.
Raynaud’s phenomenon: Fingers or toes turning blue or white in response to cold or stress.

Organ-Specific Symptoms

Kidneys: Lupus nephritis leading to swelling, high blood pressure, and protein in urine.
Lungs: Chest pain and difficulty breathing due to pleuritis.
Heart: Inflammation of heart lining, increasing risk of cardiovascular disease.
Brain & Nervous system: Headaches, confusion, memory problems, or seizures.

Because lupus affects multiple systems, symptoms can appear and disappear, adding to the complexity of diagnosis.

What Causes Lupus?

The exact lupus causes remain unclear, but research suggests it develops due to a combination of genetics, hormones, and environmental triggers.

Genetics: People with a family history of autoimmune disorders are at higher risk.
Hormonal factors: Estrogen may play a role, explaining why lupus is more common in women.
Environmental triggers: Sunlight, infections, smoking, and certain medications can trigger lupus flare-ups.
Immune dysfunction: The immune system loses its ability to distinguish between healthy cells and foreign invaders, leading to self-attack.

Additionally, lupus often overlaps with other autoimmune and endocrine disorders such as celiac disease, thyroid disorders, and type 1 diabetes, making diagnosis more challenging.

Lupus Diagnosis

Diagnosing lupus can be complex because no single test confirms the disease. Instead, doctors rely on a combination of medical history, physical exams, and lab tests.

Blood tests:

Antinuclear antibody (ANA) test – common in lupus patients.
Anti-dsDNA and anti-Smith antibodies – more specific indicators.
Complete blood count (CBC) – may show anemia or low white blood cells.

Urine tests:

To check for kidney involvement.

Imaging tests:

X-rays or echocardiograms to detect organ damage.

Clinical evaluation:

A rheumatologist evaluates the presence of hallmark symptoms like butterfly rash, joint pain, and recurrent fevers.

Treatment for Lupus

There is currently no cure for lupus, but lupus treatment focuses on managing symptoms, controlling inflammation, and preventing organ damage.

Medications

Anti-inflammatory drugs: NSAIDs help reduce joint pain and swelling.
Corticosteroids: Control severe inflammation but require careful monitoring due to side effects.
Antimalarial drugs: Hydroxychloroquine helps reduce skin rashes and joint symptoms.
Immunosuppressants: Azathioprine, methotrexate, or cyclophosphamide help control an overactive immune system.
Biologics: Targeted therapies like belimumab are used in resistant cases.

Lifestyle and Supportive Care

Balanced diet: Helps boost immunity and manage inflammation.
Stress management: Yoga, meditation, and counselling support.
Exercise: Regular activity improves joint function and overall health.
Sun protection: Using sunscreen and protective clothing to reduce flare-ups.

For severe cases involving kidney or heart complications, hospitalization may be necessary for advanced care.

Prevention and Living with Lupus

While lupus cannot always be prevented, flare-ups can be minimized by:

Avoiding sun exposure and using sun protection.
Following prescribed medications consistently.
Attending regular check-ups with a rheumatologist.
Managing stress and maintaining a healthy lifestyle.

Pregnant women with lupus should receive specialized care, as lupus can complicate pregnancy.

When to See a Doctor?

Consult a Rheumatologist if you experience:

Persistent joint pain, swelling, or stiffness.
Recurrent fevers without infection.
Rashes, particularly the butterfly rash on the face.
Unexplained fatigue and hair loss.
Symptoms suggesting kidney or heart involvement.

Early intervention can prevent serious complications and improve long-term outcomes. SPARSH is widely recognised as the best rheumatology hospital in Bangalore, with expert doctors offering advanced care.
