A wide range of symptoms can indicate if a person has polymyalgia rheumatica. The classic symptoms include:
The pathophysiology of polymyalgia rheumatica is not well-understood. Evidence shows that there is likely a combined genetic and environmental pathophysiology behind the disease, but concrete identification of the causes, including whether or not polymyalgia rheumatica is an autoimmune disease, remains elusive. It is, at the very least, an immune-mediated disease, with both innate and adaptive immune system elements being known to play a role. Infectious diseases have historically been hypothesized as a likely trigger for disease in genetically susceptible people. Individual studies have sometimes found correlations between specific pathogens and development of the disease, but broader analysis fails to find significant correlations. Proposed causative pathogens, none of which have been proven, include:
The immune cell involvement in polymyalgia rheumatica includes the activation of dendritic cells and monocytes/macrophages, leading to inflammation in the synovium and bursae of the shoulder and hip girdles which is primarily mediated by the innate immune system. There is an altered balance between Th17 and Treg cells, with increased IL-6 levels driving Th17 cell activation. Disturbed B cell distribution and function are also observed, with a decrease in circulating B cells that recover after steroid treatment. Additionally, systemic activation of circulating monocytes is associated with increased IL-6 and IL-1 beta production. Associations of uncertain significance with multiple types of TNF have also been found.
Despite the severe pain associated with the condition in multiple muscle groups, as well as the signs of systemic inflammation, muscle biopsies have found no signs of localized inflammation in muscle tissue in patients with PMR. Electromyography studies also typically turn up normal. The only locations known definitively to be inflamed in PMR are the synovial membranes and bursae of joints.
No specific test exists to diagnose polymyalgia rheumatica; many other diseases can cause inflammation and pain in muscles, but a few tests can help narrow down the cause of the pain. Limitation in shoulder motion or swelling of the joints in the wrists or hands, are noted by the doctor.
Along with medical treatment, patients are encouraged to exercise and eat healthily, helping to maintain a strong immune system and build strong muscles and bones. A diet of fruits, vegetables, whole grains, and low-fat meat and dairy products, avoiding foods with high levels of refined sugars and salt is recommended. Research in the UK has also suggested that people with polymyalgia rheumatica would benefit from a falls assessment when first diagnosed, and regular treatment reviews.
No circumstances are certain as to which an individual will get polymyalgia rheumatica, but a few factors show a relationship with the disorder:
