Clinical Causes: The exact cause of palindromic rheumatism remains unknown. It is believed to involve immune system dysfunction that causes inflammation in the joints. Genetic factors might contribute to susceptibility. Environmental triggers such as infections or stress might play a role in triggering episodes. Associated with other autoimmune conditions, indicating a possible immune-related etiology.

Key Symptoms: Sudden onset of joint pain, swelling, and tenderness. Episodes typically last from a few hours to a few days. Affected joints often include the fingers, wrists, knees, or ankles. Inflammation resolves completely between episodes, with no lasting deformity. Sometimes, episodes can be accompanied by general feelings of fatigue or malaise. Repeated episodes may lead to persistent joint issues if not managed appropriately.

Diagnosis Path: Repeated episodes of joint inflammation with symptom-free intervals. Exclusion of other forms of arthritis, such as rheumatoid arthritis or gout. Laboratory tests may show mild inflammatory markers during attacks. Blood tests might include rheumatoid factor (RF) and anti-CCP antibodies, which are typically negative in palindromic rheumatism but positive in rheumatoid arthritis. Imaging studies like X-rays are usually normal between episodes, helping differentiate from other joint diseases.

Treatment Protocols: Nonsteroidal anti-inflammatory drugs (NSAIDs) for relief during episodes. Low-dose corticosteroids may be prescribed for frequent or severe attacks. Disease-modifying antirheumatic drugs (DMARDs) might be considered if attacks become more persistent or if progression risk to rheumatoid arthritis is suspected. Lifestyle modifications such as regular exercise, physical therapy, and weight management can support joint health. Monitoring and regular medical follow-up to observe disease progression and adjust treatment plans.
