What is Psoriatic Arthritis?
Psoriasis is a multisystemic skin condition that affects many areas of the body.
1- Psoriatic arthritis (PsA) is a joint disease that occurs as a complication of psoriasis with a strong genetic component. (Figure 1). In about 47% of patients, the disease becomes destructive, leading to bone erosion and loss of joint structure. The disease can be very challenging when symptoms such as pain, and fatigue are present.
The joints commonly affected are the wrists, fingers, ankles, toes, neck, shoulder, elbows, knees, back etc.
PsA-Psoriatic Arthritis.
Erythrocyte Sedimentation Rate (ESR) – A higher ESR could indicate PsA along with markers of the disease.2
Rheumatoid factor (RF) and Anticyclic citrullinated peptide antibodies (ACPA) – These antibodies are found in most patients with PsA. Human leukocyte antigen B27 (HLA- B27) – This is a genetic marker that is present in the blood of PsA patients. Apart from these, mild anemia may be existent.
The X-ray shows bone and joint damage specific to PsA.3
PsA may contribute to loss of bone substance and it is important to keep a track of bone strength.3
