Ferritin is the principal iron storage protein participating in iron metabolism. As serum ferritin levels often reflect the amount of storage iron in the body, physicians have measured serum ferritin in order to evaluate iron deficiency or overload. Although a rise in serum ferritin concentration occurs in iron overload, hyperferritinemia without it has been reported in some inflammatory diseases and malignancies. Some cytokines have been reported to be responsible for the elevation of ferritin production. Studies on serum isoferritin in adult Still's disease and other diseases, especially measurements of the proportion of glycosylated ferritin, have been widely accepted. Pathophysiological properties of the increased serum ferritin are not clear. However, we should be aware that the hyperferritinemia is not a result, but is profoundly participating in the disease process.

Many causes provoke elevated serum ferritin levels including not only iron overload, but also many pathological situations where hyperferritinemia or modified isoferritin profiles have no direct relationship with body iron stores. There are five general categories of hyperferritinemia: hemochromatosis, inflammatory syndromes, cytolysis, hemophagocytosis, Still's disease, and other etiologies.

In three patients, two women aged 70 and 19 years and a man aged 33 years with long-lasting fever no diagnosis was made after extensive diagnostic work-up. After exclusion of infectious, malignant and rheumatic diseases, adult-onset Still's disease was diagnosed in all three patients on the basis of clinical and laboratory criteria. Adult-onset Still's disease is an important but less well known cause of fever. Clinically, adult-onset Still's disease is characterized by the triad of fever, skin rash and arthritis/arthralgia. A greatly elevated serum ferritin level proved to be an additional valuable diagnostic clue. Treatment consists of non-steroidal anti-inflammatory drugs, corticosteroids or immunosuppressive agents. The long-term prognosis is usually good, but severe joint destruction may occur. All three patients recovered.

Empyemas are usually of infectious origin. Noninfectious causes of empyema may be a considerable diagnostic challenge, as exemplified in the present case report. A 21-year-old male presented with high fever, sore throat and myalgias of 1 week duration. In the following days, bilateral pleural effusions developed, with cellular counts in the pleural fluid up to 117 x 10(9)/liter (98% neutrophils). Despite institution of empiric antibiotic therapy, spiking fever continued. All culture studies resulted in being negative. Following the report of a serum ferritin concentration of 6,975 microg/l, adult-onset Still's disease was diagnosed and successfully treated with anti-inflammatory drugs. This case adds adult-onset Still's disease to the list of noninfectious causes of empyema and underlies the value of measuring serum ferritin as a diagnostic tool.

A 25-year-old Japanese man presented with high spiking fever, arthralgia and a skin rash. A pruritic edematous erythema with persistent plaques was found mainly on the trunk; these lesions persisted even when the fever subsided, with prominent linear pigmentation. As marked neutrophilia and a high level of serum ferritin were detected, a diagnosis of adult-onset Still's disease (AOSD) was made, even though the persistent eruption was not characteristic of the disease. Oral prednisolone, together with low-dose methotrexate, was given with good results. In the literature, a similar atypical rash has been reported in 11 cases in Japan. All of them required high-dose administration of corticosteroids or other immunosuppressive agents. Severe systemic complications were seen in 3 patients, and 2 cases died of the disease. Persistent plaques and linear pigmentation are some of the manifestations of AOSD, which cannot be overlooked. This appearance could be an indication that suggests an increased risk of systemic complications and a prolonged time to clinical remission.

High-dose intravenous immunoglobulins alter the disease activity of adult-onset Still's disease (AOSD). Because activation status of FcgammaR is possibly dependent on their genetic polymorphisms, we investigated whether the polymorphisms of FcgammaR IIa and IIIa are risk factors, and affect the clinical features of AOSD. Genomic DNA was extracted from 36 patients and from 197 healthy controls. Polymerase chain reaction for FcgammaR IIa and IIIa using the allele-specific primers and direct sequencing of FcgammaR IIIa polymorphic site were performed. The frequencies of FcgammaR IIa/IIIa genotype between patients with AOSD and controls were not different. The allelic frequencies of FcgammaR IIa/IIIa between patients with AOSD and controls were not different, either. However, the FcgammaR IIa-R/R131 genotype was associated with a higher concentration of hemoglobin (p=0.04) and stable liver function (p=0.009) than the other genotypes. The FcgammaR IIIa-F/F176 genotype was associated with significantly lower titers of serum ferritin (p=0.025), and higher serum albumin (p=0.037) and cholesterol (p=0.014) concentrations than the other genotypes. This study suggest that the FcgammaR IIa and IIIa polymorphisms might not be genetic risk factors for AOSD in Korean, but contribute to the activity of disease. FcgammaR IIa-R/R131 and IIIa-F/F176 genotypes, low-binding genotypes for IgG2a and G1, may have more protective effects in acute stage of the disease than the other genotypes.

We report the case of a woman with a characteristic transient skin rash, fever, severe polyarthritis, hepatosplenomegaly, lymphadenopathy and myalgia. The clinical and laboratory data led to a diagnosis of adult-onset Still's disease. The elevated levels of serum ferritin and caeruloplasmin could be important as diagnostic indicators.

A 19-year-old woman was admitted because of high fever, rash, arthralgia and sore throat. On physical examination a diffuse skin rash was observed, leaving a facial mask unaffected. C-reactive protein and erythrocyte sedimentation rate were raised (114 mg/l and 26 mm in the first hour, respectively); white blood cell count was normal (6.2 x 10(9)/l) with an increased count of immature forms. An infective, metabolic or haematological cause was excluded. Serum ferritin turned out to be extremely elevated (4318 micrograms/l), so adult-onset Still's disease was diagnosed. The patient fulfilled the criteria of Cush et al. for adult-onset Still's disease. She was first treated with non-steroidal anti-inflammatory drugs (NSAIDs) and, at a later stage in the disease, with corticosteroids. All symptoms disappeared and blood test results normalised.

We report a case of a young woman with pyrexia and progressive lung disease who developed acute respiratory distress syndrome (ARDS) and required prolonged mechanical ventilator support. The patient had a markedly elevated serum ferritin concentration of 7880 micrograms/L, a specific finding for the adult onset Still's disease (AOSD). Treatment of the patient with supportive and immunosuppressive therapy, resulted in patient survival and cure. The early consideration of the diagnosis of AOSD in patients with fever of unknown origin and a compatible clinical course may modify its severe complications.

A 22-year-old man was admitted to our hospital with a high fever, fatigue, mild arthritis, and bilateral pleural effusions. Laboratory tests revealed a high ESR, leukocytosis, high serum C-reactive protein level, and high serum ferritin level. Various antibiotics had been given by a local hospital with no response. He was diagnosed as having severe refractory adult Still's disease and was subsequently treated with high-dose steroid therapy and low-dose cyclosporin A. The serum interleukin-18 level was monitored throughout treatment and was found to be a potentially useful marker of disease activity as well as of the response to cyclosporin A therapy.
