Psoriatic arthritis is a chronic inflammatory arthritis that develops in some people with psoriasis, affecting joints, entheses, and the spine.
Quick Answer
Psoriatic arthritis is a chronic inflammatory arthritis that develops in some people with psoriasis, affecting joints, entheses, and the spine. Dr. Shree Narayan Yadav (NMC 14227, Experienced clinical practice in internal medicine and rheumatology) evaluates psoriatic arthritis at Kathmandu Neurology Clinic & Cognitive Center, Durbar Marg, Opposite of Yak & Yeti Hotel, Kathmandu 44600, Nepal — evidence-based, medically reviewed.
Psoriatic arthritis (PsA) is a spondyloarthritis that occurs in approximately 30% of patients with the skin condition psoriasis. It causes joint pain, swelling, and stiffness, and can affect any joint in the body, including the fingers, spine, and sites where tendons attach to bone (enthesitis). The pattern of joint involvement is often asymmetric and can include dactylitis (swelling of an entire finger or toe, sausage digit). PsA can cause joint damage and disability if not treated early. Diagnosis is based on clinical features, imaging, and exclusion of other causes. Treatment includes NSAIDs, conventional DMARDs, and biologic agents targeting TNF, IL-17, or IL-23 pathways. Dr. Shree Narayan Yadav (NMC 14227) provides rheumatology consultation and treatment planning for psoriatic arthritis.
Diagnosis is based on the combination of inflammatory arthritis (asymmetric, dactylitis, enthesitis, spinal involvement) in a patient with psoriasis or a family history of psoriasis. Imaging (X-rays, MRI, ultrasound) can show erosions, new bone formation, sacroiliitis, and enthesitis. Blood tests including ESR, CRP, RF, and anti-CCP help exclude rheumatoid arthritis. There are no pathognomonic laboratory tests for PsA.
NSAIDs are first-line for mild disease. Conventional DMARDs (methotrexate, sulfasalazine, leflunomide) are used for peripheral joint disease. Biologic agents including TNF inhibitors (adalimumab, etanercept), IL-17 inhibitors (secukinumab, ixekizumab), and IL-23 inhibitors (guselkumab) are indicated for active disease not controlled by conventional therapy. Targeted synthetic DMARDs such as apremilast and JAK inhibitors offer additional options. Physiotherapy and occupational therapy support joint function.
Management is individualized and discussed with benefits, limitations, and follow-up.
There is no proven prevention for psoriatic arthritis. Early treatment of psoriasis and prompt evaluation of joint symptoms can improve outcomes. Maintaining a healthy weight, avoiding skin trauma where possible, and regular exercise support overall health.
In rare cases, arthritis may precede skin psoriasis by months or years. About 15% of PsA patients develop arthritis before visible skin disease. A family history of psoriasis supports the diagnosis.
No. PsA is a spondyloarthritis and often presents asymmetrically, with dactylitis, enthesitis, and nail changes. RA is typically symmetric and does not cause dactylitis or enthesitis. Blood tests (RF, anti-CCP) help distinguish them.
Without treatment, PsA can cause progressive joint damage, deformity, and disability. Early treatment with DMARDs or biologic therapy significantly reduces the risk of joint erosion and preserves function.
Ideally, yes. Dermatologists manage the skin disease while rheumatologists manage the joint disease. Coordinated care between both specialties ensures comprehensive treatment of both manifestations.
Yes, though it is uncommon. Joint symptoms occasionally precede the appearance of skin psoriasis by months to years. A family history of psoriasis plus characteristic patterns such as dactylitis or enthesitis support the diagnosis.
Comprehensive evaluation for joint pain, swelling, stiffness, and autoimmune conditions by Dr. Shree Narayan Yadav (NMC 14227), Consultant Physician & Joint and Autoimmune Disease Specialist.
Comprehensive assessment for undifferentiated autoimmune symptoms — fatigue, joint pain, rashes, oral ulcers, Raynaud's — with targeted serological workup.
Specialized assessment for joint pain from inflammatory and autoimmune causes — distinct from orthopedic and mechanical joint pain.
Rheumatoid arthritis is a chronic autoimmune disorder characterized by symmetric inflammation of the joints, leading to pain, swelling, stiffness, and potential joint destruction if not treated early.
Gout is a form of inflammatory arthritis caused by deposition of monosodium urate crystals in joints, resulting in sudden, severe attacks of joint pain and swelling.
Ankylosing spondylitis is a chronic inflammatory disease primarily affecting the spine and sacroiliac joints, leading to pain, stiffness, and potential fusion of the vertebrae.
