Psoriatic arthritis of psoriatic arthritis include the following: Other symptoms that are more typical of psoriatic arthritis than other forms of arthritis include enthesitis (inflammation in the Achilles tendon (at the back of the heel) or the plantar fascia (bottom of the feet)), and dactylitis (sausage-like swelling of the fingers or toes). Several conditions can mimic the clinical presentation of psoriatic arthritis including rheumatoid arthritis, osteoarthritis, reactive arthritis, gouty arthritis, systemic lupus erythematosus, and inflammatory bowel disease-associated arthritis. In contrast to psoriatic arthritis, rheumatoid arthritis tends to affect the proximal joints (e.g., the metacarpophalangeal joints), involves a greater number of joints than
Immune-mediated inflammatory diseases arthritis, inflammatory bowel disease (IBD), and allergy, as well as many cardiovascular, neuromuscular, and infectious diseases. Some current research even suggests that aging is a consequence, in part, of inflammatory processes. IMID is characterized by immune disregulation, and one underlying manifestation of this immune disregulation is the inappropriate activation of inflammatory cytokines, such as IL-12, IL-6 or TNF alpha, whose actions lead to pathological consequences. Immune-mediated inflammatory diseases An immune-mediated inflammatory disease (IMID) is any of a group of conditions or diseases that lack a definitive etiology, but which are characterized by common inflammatory pathways leading to inflammation, and which
