Adult-onset Still disease (AOSD), commonly referred in the literature as the adult form of systemic-onset juvenile idiopathic arthritis, is a disorder of unknown etiology [1] [2]. The clinical presentation might be quite different from patient to patient, but the following manifestations are included in the diagnostic criteria [1] [3] [4] [5]:

• Fever - Although not specific, the recurring appearance of very high fever (> 39°C) that lasts for a few hours and mainly happens in the late afternoon or early evening period, is a hallmark of AOSD [3] [6].
• Joint pain - The involvement of knees, wrists, or ankles is another important manifestation of AOSD [3] [4]. Arthritis usually accompanies fever and has a relatively short duration as well [3].
• Rash - A salmon-pink or erythematous nonpruritic maculopapular rash, developing together with fever and joint pain, is frequently observed, and is most commonly seen on the trunk and the proximal limbs [5].

Other common manifestations of AOSD are lymphadenopathy, hepatosplenomegaly, muscle aches, and pharyngitis [1] [7]. The clinical course of the disorder can be highly variable, ranging from mild and self-limiting to severely debilitating disease [3]. Furthermore, AOSD may cause a myriad of complications in affected individuals, such as pulmonary hypertension, thrombotic thrombocytopenic purpura (TTP), amyloidosis, and macrophage activation syndrome [1]. An early detection of this disorder could significantly aid in successful treatment and improvement of the overall quality of life.

The diagnosis of AOSD is primarily a one of exclusion, as numerous autoimmune, malignant, and infectious diseases induce the nonspecific signs and symptoms seen in this condition [1] [3] [7] [8]. Thus, a comprehensive clinical and laboratory workup is necessary. Firstly, during a history taking, patients should be asked about the course of the disease and the appearance of symptoms, whereas a thorough physical examination has an important role in identifying lymphadenopathy, cutaneous changes, joint inflammation, and hepatosplenomegaly.

A complete blood count (CBC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and serum ferritin should be evaluated in laboratory studies [1] [3] [4] [7] [8]. Additionally, rheumatoid factor (RF) and antinuclear antibodies (ANA), both performed to exclude conditions such as rheumatoid arthritis (RA) and systemic lupus erythematosus (SLE), are also recommended in the initial workup [3].

Current diagnostic criteria are divided into major (Fever ≥ 39°C, joint pain, skin rash, pharyngitis, granulocytosis of ≥ 80%, and glycosylated ferritin fraction of ≤ 20%) and minor (leukocytosis of > 10,000/mm3 and a typical skin rash) [3] [4] [7] [8]. AOSD is confirmed if ≥ 4 major criteria or 3 major and 2 minor criteria are met [1] [3] [4] [7].

• Hypoalbuminemia

  AOSD patients with RHS showed higher frequencies of leukopenia, anemia, thrombocytopenia, hypoalbuminemia, hypofibrinogenemia, hypertriglyceridemia, hyperferritinemia, and elevated lactate dehydrogenase levels than did those without RHS. [ncbi.nlm.nih.gov]

  Laboratory tests support the inflammatory nature of the disorder with leukocytosis, anemia of chronic disease, hypoalbuminemia, and hyperferritinemia. Serum rheumatoid factor and antinuclear antibodies are absent. [rheumnow.com]

  Thus, hypoalbuminemia, elevated hepatic enzymes (primarily transaminases), and aldolase elevations are seen in 60-75% of patients during active inflammatory phase of the disease. [rheumaknowledgy.com]
