There is a lot of variation. It mainly affects the small joints of the hands and feet, such as the finger (toe) joints, metacarpophalangeal joints, and metatarsophalangeal joints. It can also affect the large joints of the limbs, such as the elbows and knees, and in rare cases, the sacroiliac joints or spine. Often affected asymmetrically. Symptoms include joint swelling, pain and morning stiffness, and sometimes the entire finger becomes sausage-shaped.

(2) Skin and other manifestations

Nail or skin psoriasis may precede or follow arthritis. 80% of PA patients have abnormal nails, with "thimble-like" concave changes. Some patients may experience eye inflammation such as conjunctivitis, iritis and cornea.

(3) Laboratory examination

There are no characteristic laboratory diagnostic indicators for this disease.

(1) Mild anemia and increased erythrocyte sedimentation rate. (2) Rheumatoid factor negative. (3) Some patients, especially those with spinal involvement, may be HLA-B27 positive.

(4) Imaging examination

The distal interphalangeal joints are affected, and the distal bone of the distal phalanx is absorbed, making it thinner and pointed, with an "umbrella-shaped" or "pencil sharpener"-like change. In patients with simultaneous spinal involvement, isolated marginal or non-marginal syndesmophytes may be seen.
