Is psoriatic arthritis a contagious disease?

No, psoriatic arthritis is not a contagious disease by any means, and it cannot be transmitted from one person to another through touch or direct contact. It is a chronic inflammatory condition that arises as a result of a malfunction in the immune system, where the body attacks its own tissues without any known external cause [1], [3].

Understanding the nature of the disease

Psoriatic arthritis is classified as an autoimmune disease that occurs when the immune system becomes overactive, causing inflammation in the joints and the areas where tendons and ligaments connect to bones [3]. This disease affects between 7% to 42% of people who have skin psoriasis [1]. Although the exact causes are not fully understood, there are genetic and environmental factors that play a role in triggering the immune system to act abnormally, and infection or microbes are unrelated to this issue [3].

Symptoms that require attention

The severity and impact of symptoms vary significantly from person to person. Skin psoriasis often appears years before joint pain develops, but in rare cases, joint pain may precede the appearance of skin rashes [3]. Common symptoms that should be monitored include:

• Pain, stiffness, and swelling in one or more joints; stiffness is often more severe in the morning or after periods of rest [3].
• Full swelling of fingers or toes, giving them a sausage-like appearance [3].
• Nail changes, such as pitting (small holes appearing) or nail crumbling [1].
• Tendon inflammation, such as the Achilles tendon in the foot [1].
• Eye inflammation (such as uveitis), which appears as eye pain, redness, or blurred vision; this is a symptom that requires immediate medical intervention to avoid the risk of vision loss [3].

Diagnosis and treatment

There are no specific blood tests to diagnose this disease; instead, doctors rely on clinical examination, medical history, and assessment of signs such as joint swelling and skin and nail changes [1]. Treatment aims to reduce inflammation and pain and prevent permanent joint damage. Treatment options range from non-steroidal anti-inflammatory drugs (NSAIDs) for mild cases to disease-modifying antirheumatic drugs (DMARDs), biologic drugs, or JAK inhibitors for advanced cases [1].

Important advice

It must be emphasized that early diagnosis and starting treatment immediately play a crucial role in controlling the progression of the disease [3]. If you suffer from arthritis symptoms in conjunction with psoriasis, you should visit a rheumatologist. Avoid self-medicating, especially with oral corticosteroids, as most experts do not recommend them because they may lead to a worsening of skin psoriasis symptoms and interfere with the effectiveness of other medications [1].
