What Is Psoriatic Arthritis?
Psoriatic arthritis is an autoimmune disease where the immune system mistakenly attacks healthy tissues, leading to inflammation in the joints and skin. It typically develops in individuals with psoriasis, a skin condition characterized by red, scaly patches. About 30% of people with psoriasis develop PsA, often years after their initial psoriasis diagnosis.
Symptoms of Psoriatic Arthritis: What to Look For
PsA symptoms vary widely, but they often include a combination of joint, skin, and nail issues. Here’s a breakdown of the most common symptoms:
Joint Symptoms
-
Pain and Stiffness: Commonly affects fingers, toes, knees, and lower back. Morning stiffness is a hallmark.
-
Swelling: Fingers and toes may swell, resembling "sausage digits" (dactylitis).
-
Enthesitis: Inflammation where tendons or ligaments attach to bones, often causing heel or foot pain.
Skin and Nail Symptoms
-
Psoriasis Patches: Red, scaly rashes on the elbows, knees, scalp, or lower back.
-
Nail Changes: Pitting, discoloration, or separation from the nail bed.
Systemic Symptoms
-
Fatigue: Chronic tiredness due to systemic inflammation.
-
Eye Issues: Uveitis, causing redness, pain, and blurred vision.
Symptom Category | Common Symptoms | Notes |
---|---|---|
Joint | Pain, stiffness, swelling | Often worse in the morning |
Skin | Psoriasis patches, rashes | May appear before or after joint symptoms |
Nails | Pitting, discoloration | Affects 80-90% of PsA patients |

Psoriatic Arthritis in Seniors: A Unique Challenge
Older adults with PsA often face additional complexities due to age-related factors:
-
Comorbidities: Higher rates of cardiovascular disease, diabetes, and osteoporosis.
-
Treatment Challenges: Increased risk of drug interactions and side effects due to polypharmacy.
-
Late-Onset PsA: Symptoms may be more severe, with higher inflammatory markers and joint damage.
Treatment Options for Psoriatic Arthritis
Treatment strategies aim to reduce inflammation, manage symptoms, and prevent joint damage. Here are the main approaches:
Medications
-
NSAIDs: For mild pain and inflammation6.
-
DMARDs: Methotrexate or biologics like TNF inhibitors to slow disease progression.
-
Biologics: Target specific immune pathways, effective for both skin and joint symptoms.
Lifestyle and Dietary Changes
-
Anti-Inflammatory Diet: Rich in fruits, vegetables, and omega-3 fatty acids.
-
Exercise: Low-impact activities like yoga or swimming to maintain joint mobility.
Advanced Therapies
-
Physical Therapy: Improves joint function and reduces pain.
-
Surgery: Rarely needed, but joint replacement may be considered for severe damage.
Tips for Managing Psoriatic Arthritis
-
Early Diagnosis: Seek medical attention at the first sign of symptoms to prevent irreversible damage.
-
Regular Monitoring: Frequent check-ups to adjust treatment plans as needed.
-
Stress Management: Techniques like meditation to reduce flare triggers.
Q&A
-
Q: Can PsA be cured?
A: No, but early treatment can significantly slow disease progression and improve quality of life. -
Q: Are biologics safe for seniors?
A: Yes, but they require careful monitoring due to potential side effects and comorbidities. -
Q: What are the early signs of PsA?
A: Joint pain, stiffness, and nail changes are common early indicators. -
Q: Can diet help manage PsA?
A: An anti-inflammatory diet may reduce symptoms, though it’s not a substitute for medical treatment. -
Q: How does PsA differ from rheumatoid arthritis?
A: PsA often involves skin and nail symptoms and tends to affect joints asymmetrically.
