Gambaran umum
Psoriatic arthritis is a long-term condition where your immune system attacks your joints, causing pain, swelling, and stiffness. It often affects people who already have psoriasis — a skin condition that causes red, scaly patches.
Fakta penting
- It is an autoimmune disease — your immune system mistakenly attacks healthy tissue.
- It can affect any joint, but commonly involves the fingers, toes, spine, and knees.
- Early treatment can help prevent joint damage and improve quality of life.
Psoriatic arthritis is not as common as some other forms of arthritis, but it affects around 1 in 50 people with psoriasis. Worldwide, about 0.3 to 1% of the population has it.
It usually starts between the ages of 30 and 50, but can affect anyone, including children. Men and women are equally likely to develop it. Most people with psoriatic arthritis already have psoriasis, though sometimes the joint problems come first.
Gejala
- Sudden severe joint pain with high fever, chills, and redness — this could be a sign of infection
- Chest pain, shortness of breath, or sudden vision changes (rare but serious)
- Inability to move a joint or bear weight on a limb
- ⚠Joint pain so severe you cannot walk or use the affected joint
- ⚠Eye redness, pain, or blurred vision (possible uveitis)
- ⚠Skin blisters or very widespread red patches that are painful (sign of severe psoriasis)
- ⚠New or worsening flu-like symptoms along with joint swelling
Gejala umum
- Pain, swelling, and stiffness in one or more joints
- Morning stiffness that lasts for more than 30 minutes
- Sausage-like swelling of a whole finger or toe (dactylitis)
- Pain and tenderness where tendons or ligaments attach to bone (enthesitis), such as at the heel or bottom of the foot
- Fatigue
- Nail changes — pitting, thickening, or separating from the nail bed
- Reduced range of motion in affected joints
Gejala pada anak-anak
- Joint pain and swelling, especially in knees, ankles, and wrists
- Enthesitis (where tendons meet bone)
- Small, painful red bumps on the skin (psoriasis lesions)
- Fatigue and irritability
- Problems with nail changes (pitting, thickening)
- Eye redness or pain (uveitis) — this needs urgent medical attention
Gejala pada lansia
- More gradual onset of joint pain and stiffness in large joints like shoulders and hips
- Worsening of existing joint or tendon symptoms
- Increased risk of falls due to joint pain and stiffness
- Fatigue and weakness that can affect daily activities
- Possible overlap with osteoarthritis, which can make diagnosis trickier
Penyebab
Penyebab utama
- The exact cause is not fully known, but it is an autoimmune condition — your immune system attacks your own joints and tendons.
- Genetics play a role: certain genes (such as HLA-B27) increase the risk.
- Environmental triggers, such as infections or injury, may start the disease in people who are genetically prone.
Faktor risiko
- Having psoriasis (the skin condition) increases your risk.
- Family history of psoriatic arthritis or psoriasis.
- Age — most common between 30 and 50.
- Smoking and being overweight may increase the risk or make symptoms worse.
Kapan harus ke dokter
Segera temui dokter jika:
- Sudden, severe joint pain with swelling and fever
- Eye pain, redness, or changes in vision
- Inability to move a joint or put weight on it
- Signs of infection — redness, heat, and discharge from a joint
Buat janji temu rutin jika:
- Joint pain, swelling, or stiffness that lasts more than a few weeks
- Morning stiffness that does not go away after a few minutes
- You have psoriasis and notice any joint symptoms
- Fatigue that interferes with daily life and does not improve with rest
Diagnosis
A healthcare provider — usually a rheumatologist (joint specialist) — will take a detailed history, examine your joints and skin, and ask about your symptoms. There is no single test for psoriatic arthritis, so they will use a combination of findings to make the diagnosis.
Tes yang mungkin dilakukan
- Blood tests: to check for inflammation (e.g., C-reactive protein, ESR) and rule out other types of arthritis (like rheumatoid arthritis). Some people have a genetic marker called HLA-B27.
- Joint fluid analysis: taking fluid from a swollen joint to check for crystals or infection.
- X-rays: to look for joint damage typical of psoriatic arthritis (like 'pencil-in-cup' changes).
- MRI or ultrasound: to see inflammation in tendons and ligaments that X-rays might miss.
Apa yang diharapkan saat janji temu
Your doctor may ask about a family history of psoriasis or psoriatic arthritis, and look for skin or nail changes. It may take a few visits and tests to get a clear diagnosis. Be prepared to describe when symptoms started, which joints are affected, and how they change over the day.
Perawatan
Treatment aims to reduce pain and swelling, prevent joint damage, and help you stay active. A combination of medication, self-care, and sometimes surgery is used. Early treatment gives the best results.
Perawatan mandiri di rumah
- Stay active — gentle exercise like swimming or cycling helps maintain joint movement.
- Apply heat or cold packs to sore joints to ease pain and swelling.
- Protect your joints — use larger joints to carry loads, and take breaks.
- Maintain a healthy weight to reduce stress on joints.
- Get enough rest and sleep to manage fatigue.
Perawatan medis
Doctors may prescribe medications that calm the immune system, such as disease-modifying antirheumatic drugs (DMARDs) or biologic therapies. They may also use nonsteroidal anti-inflammatory drugs (NSAIDs) or corticosteroid injections for short-term relief. Always talk to your healthcare provider about the best options for you.
Kapan operasi dipertimbangkan?
If a joint is severely damaged and other treatments no longer control pain, joint replacement surgery (like hip or knee replacement) may help. This is not common but can be life-changing for some people.
Hidup dengan kondisi ini
Living with psoriatic arthritis means balancing activity with rest. Some days you may feel stiff and sore; other days you may feel fine. It helps to plan your day, pace yourself, and use tools that make tasks easier (like jar openers or long-handled brushes).
Tips gaya hidup
- Stay physically active — aim for low-impact exercises like walking, stretching, or yoga.
- Quit smoking — it worsens both psoriasis and arthritis.
- Limit alcohol, as it can interfere with some medications.
- Protect your skin from sun and injury to avoid triggering psoriasis flares.
- Work with an occupational therapist to find ways to do daily tasks more comfortably.
Diet dan olahraga
A healthy, balanced diet rich in anti-inflammatory foods (like fruits, vegetables, whole grains, and omega-3 fatty acids from fish) may help reduce symptoms. Avoid crash diets. Exercise is important — gentle stretching, strengthening, and aerobic exercise help maintain joint function and mood. Always consult a physiotherapist before starting a new program.
Kesehatan mental dan kesejahteraan emosional
Living with a chronic condition can be stressful. Many people with psoriatic arthritis feel anxious or depressed. It is normal to have these feelings, and you should talk to your healthcare provider. If you experience thoughts of self-harm, call your local emergency number or a crisis helpline immediately. You are not alone.
Pencegahan
There is no known way to prevent psoriatic arthritis. However, if you have psoriasis, keeping your skin condition well-controlled and avoiding triggers (like stress, infections, and smoking) may lower your risk or delay onset.
Vaksin
People with psoriatic arthritis, especially those on immunosuppressive medications, should keep up to date with recommended vaccines (like flu and pneumonia vaccines). Some vaccines may need to be avoided or spaced out — discuss with your healthcare provider.
Program skrining
There are no routine screening tests for psoriatic arthritis in the general population. If you have psoriasis, your doctor may check your joints and nails regularly for early signs of arthritis.
Komplikasi
Jika tidak diobati
- Permanent joint damage and deformities
- Reduced mobility and disability
- Increased risk of cardiovascular disease (heart attack, stroke)
- Fatigue, depression, and reduced quality of life
- Osteoporosis (weakened bones) from chronic inflammation
Prospek jangka panjang
With the right treatment, most people with psoriatic arthritis can manage their symptoms and lead a full, active life. Early diagnosis and treatment are key to preventing joint damage. While there is no cure, ongoing research continues to improve treatment options and outcomes.
