It has been reported that some patients have been misdiagnosed with SLE, when in fact the correct diagnosis in their specific case was Psoriatic Arthritis.
There is no cure for psoriatic arthritis. The aim of the treatment is to get the inflammation under control and reduce joint pain. Anti-inflammatory medication as well as disease modifying antirheumatic drugs are mostly prescribed. If the joints are badly damaged, surgery to replace damaged joints is recommended. Steroid injections administered to the affected joints can also be helpful. Diagnosis of psoriatic arthritis is mainly aided by eliminating other conditions that produce similar symptoms. There is no specific test to confirm diagnosis but imaging tests are sometimes done to check for some markers.
