It shares characteristics of systemic-onset juvenile idiopathic arthritisbut it begins in adulthood. Inflammation may affect a few joints at first, but may advance to include more joints over time. Some people may have only one bout of the illness followed by lasting remission, while others may develop chronic arthritis.
Some individuals may only develop one random episode that responds to treatment and resolves within one year. In some cases, a new episode does not occur or does not occur until many years later. Other individuals may develop chronic disease, in which episodes come and go, often years apart and with no symptoms in-between episodes.
This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed.
Its pathophysiology is yet to be completely elucidated, but is known to consist mainly on a cytokine cascade, responsible for the systemic manifestations. AOSD diagnosis is usually difficult and delayed, with physicians having to rule out several other conditions, including cancer or infectious diseases. In addition, treatment remains to be codified, especially considering the development of new drugs.
Adult-onset Still's disease AOSD is a form of Still's diseasea rare systemic autoinflammatory disease characterized by the classic triad of persistent high spiking feversjoint painand a distinctive salmon-colored bumpy rash. The disease is considered a diagnosis of exclusion. AOSD may present in a similar manner to other inflammatory diseases and to autoimmune diseaseswhich must be ruled out before making the diagnosis.
There is also a pediatric version called systemic onset juvenile inflammatory arthritis SoJIA. AOSD is classified as an inflammatory illness that often causes fatigue and swelling in joints, tissues, organs, and lymph nodes. The primary symptoms include:.
The more common clinical manifestations are spiking fevers, arthritis, evanescent rash, elevated liver enzymes, lymphadenopathy, hepatosplenomegaly, and serositis. The multi-visceral involvement of the disease and the different complications, such as macrophage activation syndrome, may strongly decrease the life expectancy of AOSD patients. This study aimed to identify the positive and negative features correlated with the outcome of patients. A retrospective analysis of AOSD patients prospectively admitted to three rheumatologic centers was performed to identify the clinical features present at the time of diagnosis and to predict the possible outcome.

Within the United States, the twentieth century was marked by an overall increase in life expectancy of about six years in both men and women, raising the average life span to 74 years in men and almost 80 years in women. Recently, however, mortality seems to be increasing, and it appears to be doing so at different rates in different areas of the country.
