[Adult onset Still's disease with normal level of serum ferritin]

We present a case of an adult onset Still's disease: a 51 year old men presented with one month history of high spiking fever, asymmetric migratory polyarthritis and a previous history of pharyngitis. The diagnostic was based upon clinical criteria and laboratory findings, and necessitated the exclusion of infectious, neoplastic, and other "autoimmune" disease. The systemic involvement in our case induced us to comment therapy with corticosteroid. Patients with systemic disease have a favorable prognosis, with only rare serious complications from the disease (pericarditis, tamponade, diffuse intravascular coagulation, amyloidosis, hepatic disease, and respiratory failure) or the treatment (infections, gastrointestinal bleeding etc.).

Severe systemic inflammatory response syndrome in a patient with adult onset Still's disease treated with the anti-IL1 drug anakinra: a case report

Interleukin 1 (IL1) plays an important role in adult onset Still's disease. Anakinra (Kineret), a recombinant IL1 Receptor Antagonist (IL 1 RA) was therefore recently proposed in adult onset Still's disease with great efficacy. Anakinra appeared to be well tolerated and safe. The case of a patient with refractory adult onset Still's disease who experienced a Systemic Inflammatory Response Syndrome and Adult Respiratory Distress Syndrome requiring intensive care unit hospitalization 10 days after the introduction of anakinra is reported.

Adult onset Still's disease: a study of 14 cases

We studied the clinical profile, laboratory parameters, disease course, and outcomes of patients with adult onset Still's disease (AOSD). A retrospective analysis of adult patients with Still's disease diagnosed from 2000 to 2004 was carried out. Their clinical features and laboratory findings at presentation, disease course, and outcomes were analyzed. Data of 14 patients with Still's disease were analyzed. The age at disease onset ranged from 16 to 59 years with a mean of 29.85, the male to female ratio being 9:5. The mean duration of illness from onset of symptoms to presentation was 14.5 months (range). The most common clinical manifestations were fever (n = 14), articular symptoms (n = 14), rash (n = 8), weight loss (n = 12), and sore throat (n = 5). Elevated ESR was present in all patients with a mean of 98.3 mm at 1 h. Hepatic enzymes were elevated in seven patients at disease onset. The mean duration of follow up was 19.14 months (range). Three patients progressed to chronic arthropathy. Cyclosporine led to dramatic recovery in five patients. Macrophage activation syndrome (MAS) was present in two patients, one after sulfasalazine therapy. One patient with MAS died. Still's disease, although uncommon, has characteristic constellation of clinical and laboratory features and should be considered in the differential diagnosis of fever of unknown origin. Nonsteroidal anti-inflammatory drugs, steroids, and methotrexate may not be always effective, and cyclosporine is an effective drug in resistant cases. Sulfasalazine should be avoided in cases of AOSD.

Adult-onset Still's disease: can recent advances in our understanding of its pathogenesis lead to targeted therapy?

Adult-onset Still's disease is a rare systemic inflammatory disease of unknown etiology, characterized by daily high, spiking fevers, evanescent rash, and arthritis. There is no single diagnostic test for adult-onset Still's disease; rather, the diagnosis is based on clinical criteria and necessitates the exclusion of infectious, neoplastic, and other 'autoimmune' diseases. Proinflammatory cytokines such as interleukin (IL)-1, IL-6, and IL-18, interferon-gamma, tumor necrosis factor, and macrophage colony-stimulating factor are elevated in patients with adult-onset Still's disease and are thought to have a major role in the pathogenesis of the disease. Treatment consists of nonsteroidal anti-inflammatory drugs, corticosteroids, immunosuppressants (methotrexate, gold, azathioprine, leflunomide, cyclosporin, and cyclophosphamide), intravenous immunoglobulin, and cytokine (tumor necrosis factor, IL-1 and IL-6) inhibitors. Recent advances in basic immunology have enhanced our ability to hinder the pathogenic mechanisms associated with adult-onset Still's disease and have led to a paradigm shift where targeted treatments have an increasingly important role.

Enfermedad de Still del adulto: revisión de 26 casos

BACKGROUND AND OBJECTIVE

We intended to describe the clinical characteristics, treatment and evolution of 26 patients with adult onset Still's disease.

PATIENTS AND METHOD

This was a retrospective study (1984-2004). The clinical records of patients with adult onset Still's disease were reviewed.

RESULTS

Twenty six patients were included. Most frequent clinical characteristics were: fever (100%), arthritis (81%), rash (92%) sore throat (92%) and lymphadenopathy (42%). Aspirin controlled the disease in 27% of patients, prednisone was needed in 70% and methotrexate was added in 50% cases. A monocyclic course was seen in 54% and polycyclic in 46% patients.

CONCLUSIONS

The clinical characteristics were similar to previous series. A febrile polyarthritis was the most frequent presentation form. A polycyclic course was found in 58% of cases and it seems to be associated with poor prognosis and need for aggressive treatment.

Anakinra in patients with treatment-resistant adult-onset Still's disease: four case reports with serial cytokine measurements and a review of the literature

OBJECTIVE

To determine the efficacy of the interleukin (IL)-1-receptor antagonist (IL-1RA) anakinra in patients with adult-onset Still's disease (AOSD) refractory to standard treatments such as glucocorticosteroids (GC), immunosuppressive drugs, and tumor necrosis factor (TNF)-antagonists; to verify disease remission objectively by serial cytokine measurements; and to review the current literature on anakinra for this indication.

METHODS

Four patients with AOSD--2 with acute flares of the chronic form of the disease and 2 with intermittent disease--were treated with prednisolone and methotrexate. One was also treated with several other immunosuppressive drugs including etanercept and infliximab. One patient had life-threatening symptoms (toxic megacolon, pneumonitis, disseminated intravascular coagulation) despite high-dose prednisolone. Treatment with anakinra 100 mg/d subcutaneously was initiated. White blood cells (WBC), C-reactive protein (CRP) levels, erythrocyte sedimentation rate (ESR), liver enzymes, ferritin levels, and serum cytokines were analyzed. The current literature on the efficacy of anakinra for AOSD is reviewed.

RESULTS

Patients with chronic AOSD quickly responded to anakinra treatment (1 day to 3 days). GC could be tapered. ESR, CRP, WBC, ferritin, and liver enzymes returned to normal. Serum cytokine measurements revealed moderately elevated IL-1beta levels and highly elevated IL-18 levels in active disease, which normalized with anakinra. TNF-alpha and IL-6 were moderately elevated only in the 2 patients with chronic AOSD. In the literature, 17 similar cases have been reported to date.

CONCLUSIONS

Anakinra is effective in treatment-resistant and in life-threatening AOSD. IL-18 serum levels, in addition to CRP, ESR, liver enzymes, ferritin, and WBC, may be helpful in assessing disease activity and response to treatment.

Chronic Anemia and Thrombocytosis as the Initial Presentation of Still’s Disease in an Elderly Patient

Still's disease is very rare in elderly patients. We report a case of Still's disease in an elderly patient that had an atypical initial presentation. A 76-year-old woman developed unexplained chronic anemia and thrombocytosis. Three years later she had acute onset of high fever, arthritis, maculopapular rash, pleuritic chest pain, abdominal pain, lymphadenopathy and elevated erythrocyte sedimentation rate. Rheumatoid factor and antinuclear antibodies were negative. She responded favorably to prednisone and methotrexate treatment. Anemia and thrombocytosis as well as Still's disease manifestations resolved.

Successful treatment of a patient with refractory adult Still's disease by tacrolimus

Adult Still's disease (ASD) is a systemic rheumatic disease characterized by high spiking fever, erythema, polyarthritis, and increased levels of C-reactive protein, ferritin, and interleukin (IL)-18. Recently, biological agents targeting proinflammatory cytokines such as tumor necrosis factor (TNF) alpha, IL-1, and IL-6 have been described as effective treatments for refractory ASD. Herein, we present a patient with ASD, who was successfully treated by tacrolimus concomitant with corticosteroid, while infliximab and etanercept were not effective. Tacrolimus may be one of the drugs for the ASD patients refractory to the conventional treatments including TNF inhibitors.

Adult-onset Still's disease in a patient over 80 years old successfully treated with low-dose methotrexate therapy

We report on an 83-year-old Japanese woman with adult-onset Still's disease (AOSD), with marked hypercytokinemia (serum levels of ferritin (Fer) and interleukin (IL)-18 were markedly high). On seeing older patients with fever of unknown origin (FUO), particularly Asians, AOSD should be considered. Reduced doses of oral prednisolone following intravenous methylprednisolone (mPSL) therapy caused a flare-up of AOSD and led to Pneumocystis carinii (jeroveci) pneumonia. Low-dose methotrexate (MTX) therapy was administered as a steroid-sparing agent with good response. Our case suggests that in very elderly people, as in younger patients, MTX is useful for controlling AOSD with marked hypercytokinemia, and avoiding corticosteroid-induced adverse effects.

Pathogenesis and Management of Adult-Onset Still’s Disease

OBJECTIVE

To review recent literature regarding the pathogenesis and treatment of adult-onset Still's disease (AOSD).

METHODS

We searched MEDLINE and PUBMED from 1971 to present using the following terms: adult-onset Still's disease, AOSD, or adult Still's disease. In addition we manually retrieved relevant abstracts from recent American College of Rheumatology and European League Against Rheumatism meetings.

RESULTS

The etiology of AOSD, a rare, immune-mediated, multisystem inflammatory disorder characterized by quotidian spiking fevers, evanescent rash, and arthritis, remains unknown. An infectious etiology has been postulated, although a definitive agent has yet to be identified. Cytokines, such as interleukin (IL)-1, IL-6, interferon (IFN)-gamma, and tumor necrosis factor-alpha, are elevated in patients with AOSD. IL-18 and macrophage-colony stimulating factor also seem to play a role. Treatment historically consisted of nonsteroidal antiinflammatory drugs, often in combination with low-dose corticosteroids. Immunosuppressants (mainly methotrexate, but also intramuscular gold, azathioprine, cyclosporine A, leflunomide, and cyclophosphamide) and intravenous gamma-globulin are efficacious and have been used as steroid-sparing drugs. The recently reported use of anticytokine (anti-TNF-alpha, anti-IL-1, and anti-IL-6) agents in refractory cases has opened new horizons in the treatment of AOSD and provided important clues for its pathophysiology.

CONCLUSIONS

Advances in immunology have enhanced our understanding of the role of cytokines in AOSD pathogenesis. Early, promising studies of anticytokine agents in AOSD may provide further insight into the pathogenetic mechanisms of this complex disease.

Ten years of clinical experience with adult onset Still’s disease: is the outcome improving?

This study aims to report on the clinical and laboratory picture and the disease course and outcome in patients having adult onset Still's disease (AOSD), to briefly review existing literature on the subject, and to compare our findings with those previously reported. Results are reported for 28 patients with AOSD satisfying the preliminary criteria of Yamaguchi et al. seen in a teaching hospital over the last 10 years. A high percent of the patients with AOSD were women. The mean (+SD) age at disease onset was 27.8 (+8.4) years. We found fever in 100%, rash in 85%, arthritis in 64%, lymphadenopathy in 60%, splenomegaly in 57%, hepatomegaly in 35%, pleural effusion in 17.9%, and pericardial effusion in 3.6% of our patients. Leukocytosis was present in 96% of the patients, a normochromic, normocytic anemia in 54%, and an elevated erythrocyte sedimentation rate (ESR) in all. Serum ferritin levels were raised in 89% of the patients. The mean follow-up of the patients was 3.72 + 2.46 years. The mean delay in diagnosis was 7.32 + 18.0 months. The mean time to enter remission was 9.7 months. Self-limited, intermittent, and chronic disease course was seen in 14.3, 57.1, and 28.6% of patients, respectively. The outcome was good in about 89% of patients, and mortality was nil. No particular clinical or laboratory variable was found to predict the subsequent disease course and outcome in our patients. On comparing our data with important previous series, we found a higher percentage of women and of patients presenting in the age group 16-35 years, a lower frequency of arthritis and pericardial effusion, and some other notable differences. Importantly, the disease course was benign, probably as an outcome of heightened awareness and less diagnostic delay than in the past, allowing for early, aggressive, and appropriate treatment. It is concluded that AOSD is now a relatively benign disease if diagnosed early and treated appropriately.

Enfermedad de Still del adulto con manifestaciones cutáneas atípicas

Adult Still's disease (ASD) is an uncommon inflammatory disease of unknown etiology. It is characterized by the triad of intermittent high fever, evanescent rash and polyarthralgia or polyarthritis. We present the case of a 29-year-old woman with ASD and persistent erythematous papule on neck and upper part of the trunk. The presence of fixed lesions is not characteristic of ASD, but its appearance during development of the disease suggests that they are a manifestation of it. Recently, other skin manifestations of ASD have been published, but they are not well-known.

57-year-old Asian-American man with Kikuchi's disease

Kikuchi's Disease (KD) is a subacute necrotizing lymphadenitis more commonly reported from Asia. The classic presentation includes low-grade fever and cervical lymphadenopathy in a previously healthy woman. The ratio of affected women to men is 4:1 with the average age of onset less than 30 years. We report a case of KD in a 57-year-old Asian-American man whose presentation is associated with Adult Still's Disease.

Successful treatment of acquired amegakaryocytic thrombocytopenia with cyclosporine in adult onset Still's disease

Acquired amegakaryocytic thrombocytopenia (AAT) is a rare disorder, characterized by severe thrombocytopenia and selective, marked decrease or absence of megakaryocytes in the bone marrow. We describe a 29-year-old female with adult onset Still's disease preceding a diagnosis of AAT and autoimmune hemolytic anemia, which was successfully treated with cyclosporine. This is the first case of AAT in a patient with adult onset Still's disease.

Profils évolutifs et marqueurs pronostiques de la maladie de Still de l'adulte. Analyse d'une série monocentrique de 17 patients

Adult-Onset Still's disease (AOSD) is a rare condition of unknown origin with various presentations and unpredictable outcome. The aim of this study was to analyse clinical and biological presentation, and outcome of patients admitted to an internal medicine service.

METHOD

A retrospective cohort design with prospective follow-up was used. All the patients admitted to our internal medicine service for AOSD between January 1998 and March 2004 were included.

RESULTS

According to Yamaguchi's classification criteria, 17 patients were analysed with a mean age at onset of 37.3 years and a 2.4 sex-ratio (female/male). Mean follow-up length was 52.1 months. Eight patients developed a monocyclic systemic form, 8 a polycyclic systemic form and 1 a chronic articular form. Arthralgia (87%) and arthritis (53%) were less frequent than in other series. Sixteen patients were treated: 14 by corticosteroids, 6 by non-steroid anti-inflammatory drugs, 5 by methotrexate, 2 intravenous polyglobulin and one by anti-TNF drug. Patients with a corticodependant or corticoresistant form had more polyarthritis at the onset of the disease (3/6 vs 0/11, P=0.029).

DISCUSSION

In internal medicine activity, AOSD without oligo- or polyarthritis may be more frequent than expected according to the literature. Corticotherapy alone is often efficient in these AOSD form without synovitis, and methotrexate use is uncommon.
