Lupus

Lupus is a chronic autoimmune disease that can affect nearly any part of the body. In a healthy individual, the immune system defends against foreign invaders like viruses and bacteria. However, with Lupus, the immune system mistakenly attacks healthy tissues and organs, leading to inflammation and tissue damage. This condition is known for its wide range of symptoms, which can vary significantly from person to person, making diagnosis and management a complex journey. Understanding Lupus is crucial for effective treatment and improving the quality of life for those living with it.

Lupus, often referred to simply as SLE (Systemic Lupus Erythematosus), is a long-term autoimmune disorder. The immune system, which is designed to protect the body from illness and infection, becomes hyperactive and starts attacking healthy cells and tissues. This widespread assault can impact various organs, including the skin, joints, kidneys, brain, heart, lungs, and blood cells. The inflammation caused by Lupus can lead to pain, swelling, and damage in the affected areas. It's a condition that can manifest differently in each individual, with periods of active disease (flares) and periods of remission.

Lupus is more common than many people realise. Globally, it's estimated to affect around 5 million people.While it can affect people of all ethnic backgrounds, it is more prevalent and often more severe in individuals of African, Asian, and Hispanic descent. The exact reasons for these demographic disparities are still being researched.

While Systemic Lupus Erythematosus (SLE) is the most common form, there are several other types of Lupus:

• Systemic Lupus Erythematosus (SLE): This is the most prevalent form, affecting various organs and systems in the body.
• Cutaneous Lupus Erythematosus (CLE): This type primarily affects the skin, causing rashes and lesions. It can manifest as discoid lupus (thick, scaly lesions, often on the face and scalp) or subacute cutaneous lupus (red, scaly patches, usually on sun-exposed areas).
• Drug-Induced Lupus: This form is triggered by a reaction to certain medications. Symptoms are often similar to SLE but tend to be milder and typically resolve once the offending drug is stopped. Common culprits include hydralazine, procainamide, and isoniazid.
• Neonatal Lupus: This is a rare condition that affects infants born to mothers with certain antibodies. It can cause skin rashes, liver problems, and blood count abnormalities in the baby, which usually disappear within several months. In some cases, it can lead to a serious heart condition in the baby.

The exact cause of Lupus is not fully understood, but it is believed to involve a complex interplay of genetic predisposition and environmental triggers. It's not contagious and cannot be passed from person to person.

• Genetics: While there isn't a single "Lupus gene," individuals with a family history of autoimmune diseases may have a higher risk. Certain genes have been identified that are more common in people with Lupus.
• Environmental Triggers: Exposure to certain environmental factors can potentially trigger Lupus in genetically susceptible individuals. These include:
  • Sunlight: Ultraviolet (UV) light, particularly from the sun, can cause skin lesions and trigger flares in some people with Lupus.
  • Infections: Viral infections, such as Epstein-Barr virus, have been implicated as potential triggers.
  • Medications: As mentioned with drug-induced lupus, certain drugs can induce Lupus-like symptoms.
  • Hormones: The fact that Lupus affects women predominantly, especially during their reproductive years, suggests that hormones, particularly oestrogen, may play a role.

Lupus is often called "the great imitator" because its symptoms can mimic many other conditions, making diagnosis challenging. Symptoms can appear suddenly or develop slowly, can be mild or severe, and may be temporary or permanent. Common symptoms include:

• Fatigue: Persistent and overwhelming tiredness, even after adequate rest.
• Joint Pain and Swelling: Often symmetrical, affecting small joints of the hands and feet.
• Muscle Aches: Widespread muscle pain.
• Skin Rashes: The characteristic "butterfly rash" (malar rash) across the cheeks and bridge of the nose is common, but other rashes can also occur, particularly after sun exposure.
• Fever: Often a low-grade fever without an obvious cause.
• Hair Loss: Can be temporary or permanent, sometimes appearing in patches.
• Raynaud's Phenomenon: Fingers and toes turn white or blue when exposed to cold or stress.
• Oral or Nasal Ulcers: Sores that appear in the mouth or nose, usually painless.
• Chest Pain: Pleurisy (inflammation of the lining around the lungs) or pericarditis (inflammation of the lining around the heart).
• Kidney Problems: Lupus nephritis, leading to swelling in the legs, high blood pressure, and impaired kidney function.
• Neurological Issues: Headaches, memory problems, confusion, seizures, or strokes in severe cases.
• Blood Problems: Anaemia, low white blood cell count, or low platelet count.

Diagnosing Lupus can be a lengthy process due to its diverse and fluctuating symptoms. There isn't a single definitive test for Lupus. Doctors rely on a combination of factors:

• Medical History and Physical Examination: A thorough review of symptoms, family history, and a physical assessment.
• Blood Tests:
  • Antinuclear Antibody (ANA) Test: A positive ANA test is highly indicative of Lupus, though it can also be positive in other autoimmune conditions or healthy individuals.
  • Anti-dsDNA and Anti-Sm Antibody Tests: These antibodies are more specific to Lupus and can help confirm the diagnosis.
  • ESR (Erythrocyte Sedimentation Rate) and CRP (C-Reactive Protein): These tests measure inflammation levels in the body.
  • Complete Blood Count (CBC): Checks for anaemia, low white blood cells, or low platelets.
  • Kidney and Liver Function Tests: To assess organ involvement.
• Urine Tests: To check for protein or blood in the urine, indicating kidney involvement.
• Biopsies: Skin biopsy (for rashes) or kidney biopsy (for suspected kidney involvement) can provide crucial diagnostic information.
• Imaging Tests: X-rays, MRI, or echocardiograms may be used to assess specific organ involvement, such as the heart or lungs.

There is currently no cure for Lupus, but treatments aim to manage symptoms, reduce inflammation, prevent flares, and minimise organ damage. Treatment plans are highly individualised and may change over time.

• Non-steroidal Anti-inflammatory Drugs (NSAIDs): For mild joint pain and inflammation (e.g., ibuprofen, naproxen).
• Antimalarial Drugs: Hydroxychloroquine (Plaquenil) is a cornerstone of Lupus treatment. It helps with fatigue, joint pain, skin rashes, and can reduce flares.
• Corticosteroids: Powerful anti-inflammatory drugs like prednisone (Brands available: Wysolone, Omnacortil) are used to control severe flares and reduce inflammation in vital organs. Long-term use carries side effects.
• Immunosuppressants: Drugs that suppress the overactive immune system, such as methotrexate, azathioprine, mycophenolate mofetil, and cyclophosphamide, are used for more severe Lupus, especially with organ involvement.
• Biologics: Newer medications like belimumab (Benlysta) specifically target certain immune cells or pathways involved in Lupus.
• Rituximab: A monoclonal antibody used in some severe cases, particularly when other treatments are ineffective.
• Lifestyle Modifications: Sun protection, a balanced diet, regular exercise (as tolerated), and stress management are important complementary approaches.

While alternative therapies should never replace conventional medical treatment for Lupus, some people find certain approaches helpful for managing symptoms and improving well-being. Always discuss any alternative therapies with your doctor before starting them, as some can interfere with medications or have adverse effects.

• Acupuncture: Some individuals report relief from pain and fatigue.
• Mind-Body Practices: Techniques like meditation, yoga, and tai chi can help manage stress, improve mood, and potentially reduce pain.
• Dietary Changes: While no specific "Lupus diet" exists, some people find that reducing processed foods, increasing omega-3 fatty acids, and identifying potential food sensitivities can help.
• Supplements: Vitamin D supplementation is often recommended as many people with Lupus have low levels, and it plays a role in immune function. Other supplements like fish oil may offer anti-inflammatory benefits.

• Female sex (9 times more likely than men).
• Age (most commonly diagnosed between 15 and 44).
• Ethnicity (more prevalent and severe in people of African, Asian, and Hispanic descent).
• Family history of autoimmune diseases.
• Exposure to certain environmental triggers (sunlight, infections, specific medications).

• Kidney damage (Lupus nephritis), potentially leading to kidney failure.
• Cardiovascular disease (heart attacks, strokes, high blood pressure).
• Lung problems (pleurisy, pneumonitis, pulmonary hypertension).
• Nervous system issues (headaches, seizures, memory problems, psychosis).
• Blood disorders (anaemia, blood clots, low platelet count).
• Increased risk of infections due to immunosuppressive medications.
• Bone damage (osteoporosis, avascular necrosis).

• Prioritise Sun Protection: Always use high-factor sunscreen, wear protective clothing, and seek shade, especially during peak hours.
• Manage Fatigue: Listen to your body, pace yourself, and build rest periods into your day.
• Eat a Balanced Diet: Focus on whole, unprocessed foods, fruits, vegetables, and lean proteins.
• Stay Active: Engage in regular, gentle exercise as tolerated to maintain joint flexibility and reduce stiffness.
• Seek Support: Connect with support groups, friends, or family who understand your journey.

Myth: Lupus is Contagious.

Lupus is an autoimmune disease and cannot be spread from person to person.

Myth: Lupus Only Affects the Skin. 

While skin rashes are common, Lupus can affect nearly any organ or system in the body.

Myth: Lupus is a Rare Disease. 

While not as common as some other conditions, Lupus affects millions worldwide and is not as rare as often perceived.

If you experience persistent, unexplained fatigue, joint pain, skin rashes (especially a butterfly-shaped rash on your face), fevers, or other symptoms that don't go away, it's crucial to see your GP. Early diagnosis and treatment of Lupus can significantly improve outcomes and prevent serious complications. If you have already been diagnosed with Lupus, consult your doctor immediately if you experience new or worsening symptoms, signs of an infection, or side effects from your medication.
