Introduction: Adult Still's disease is a rheumatic, inflammatory, systemic and chronic disease whose prevalence in the Caucasian population is estimated at 1 case per 100,000 adults. Objective: To present a young adult patient with a fever of unknown origin as the presentation of adult Still's disease. Clinical case: 29-year-old patient with a history of rheumatic fever, with a previous hospital admission; who presented a non-infectious febrile illness lasting 50 days, for which the cause was not determined. A year later, the fever reappeared, with similar characteristics, associated with polyarthralgia, hepatosplenomegaly, anemia, hyperferritinemia, neutrophilia, negative rheumatoid factor, and pericarditis was noted during admission. The diagnosis of adult Still's disease was made by exclusion. Treatment with steroids was started, the fever disappeared in the first 24 hours and the patient had a favorable evolution. Conclusions: Adult Still's disease can present as a fever of unknown origin and is diagnosed by exclusion, since there are no pathognomonic clinical manifestations or laboratory tests. Hyperferritinemia is useful for diagnostic suspicion(AU)

Differential diagnosis of adult-onset Still's disease with other fever of unknown origin causes / 解放军医学杂志

Objective To explore the differential diagnostic indicators of adult-onset Still's disease(AOSD)from other fever of unknown origin(FUO).Methods The clinical data and laboratory indicators of 177 AOSD patients and 163 FUO patients who were hospitalized in the First Affiliated Hospital of Army Medical University from January 2010 to May 2021 were collected,and the patients were randomly divided into training group and verification group.Statistically significant variables were extracted from univariate analysis for receiver operating characteristic(ROC)curve analysis and the best cut-off value of the variables was obtained.The differential diagnostic indicators were extracted by multivariate logistic regression analysis and nomogram model was constructed.ROC curve,calibration curve,and decision curve analysis were used to evaluate the accuracy and stability of nomogram.Results Univariate analysis revealed that there were significant differences in 4 clinical features(arthralgia,rash,pharyngeal pain,myalgia)and 14 laboratory parameters[white blood cell count(WBC),monocyte percentage,neutrophil percentage,lymphocyte percentage,platelet count,C-reactive protein,interleukin-6(IL-6),ferritin,globulin,immunoglobulin A,and immunoglobulin G(IgG),creatine kinase,creatinine and complement C3].Multivariate analysis suggested that arthralgia,WBC≥9.995×109/L,IL-6≥98.13 ng/L,ferritin≥507.37 ng/ml,globulin≤36.58g/L,IgG≤13.59g/L,complement C3≥1.27 g/L were related with AOSD.The area under curve(AUC)values of training group and verification group were 0.917(95%CI 0.883-0.951)and 0.869(95%CI 0.802-0.936),respectively.The calibration curves showed good consistency.The decision curve analysis showed that training group and verification group had a large positive rate of return in the wide risk range of 5%-85%and 10%-85%,respectively.Conclusions This study has established a relatively accurate AOSD differential diagnosis model.The combination of arthralgia,WBC,IL-6,ferritin,globulin,IgG and complement C3 may help to distinguish AOSD from other causes of FUO.

Clinical characteristics and diagnostic indicators of macrophage activation syndrome in patients with systemic lupus erythematosus and adult-onset Still's disease / 北京大学学报(医学版)

OBJECTIVE@#To analyze and compare the clinical and laboratory characteristics of macrophage activation syndrome (MAS) in patients with systemic lupus erythematosus (SLE) and adult-onset Still's disease (AOSD), and to evaluate the applicability of the 2016 European League Against Rheumatism/American College of Rheumatology/Paediatric Rheumatology International Trials Organization classification criteria for MAS complicating systemic juvenile idiopathic arthritis (sJIA) in different auto-immune diseases contexts and to propose new diagnostic predictive indicators.@*METHODS@#A retrospective analysis was conducted on the clinical and laboratory data of 24 SLE patients with MAS (SLE-MAS) and 24 AOSD patients with MAS (AOSD-MAS) who were hospitalized at Peking University People's Hospital between 2000 and 2018. Age- and sex-matched SLE (50 patients) and AOSD (50 patients) diagnosed in the same period without MAS episodes were selected as controls. The cutoff values for laboratory indicators predicting SLE-MAS and AOSD-MAS were determined using receiver operating characteristic (ROC) curves. Furthermore, the laboratory diagnostic predictive values for AOSD-MAS were used to improve the classification criteria for systemic juvenile idiopathic arthritis-associated MAS (sJIA-MAS), and the applicability of the revised criteria for AOSD-MAS was explored.@*RESULTS@#Approximately 60% of SLE-MAS and 40% of AOSD-MAS occurred within three months after the diagnosis of the underlying diseases. The most frequent clinical feature was fever. In addition to the indicators mentioned in the diagnosis criteria for hemophagocytic syndrome revised by the International Society for Stem Cell Research, the MAS patients also exhibited significantly elevated levels of aspartate aminotransferase and lactate dehydrogenase, along with a significant decrease in albumin. Hemophagocytosis was observed in only about half of the MAS patients. ROC curve analysis demonstrated that the optimal discriminative values for diagnosing MAS was achieved when SLE patients had ferritin level≥1 010 μg/L and lactate dehydroge-nase levels≥359 U/L, while AOSD patients had fibrinogen levels≤225.5 mg/dL and triglyceride levels≥2.0 mmol/L. Applying the 2016 sJIA-MAS classification criteria to AOSD-MAS yielded a diagnostic sensitivity of 100% and specificity of 62%. By replacing the less specific markers ferritin and fibrinogen in the 2016 sJIA-MAS classification criteria with new cutoff values, the revised criteria for classifying AOSD-MAS had a notable increased specificity of 86%.@*CONCLUSION@#Secondary MAS commonly occurs in the early stages following the diagnosis of SLE and AOSD. There are notable variations in laboratory indicators among different underlying diseases, which may lead to misdiagnosis or missed diagnosis when using uniform classification criteria for MAS. The 2016 sJIA-MAS classification criteria exhibit high sensitivity but low specificity in diagnosing AOSD-MAS. Modification of the criteria can enhance its specificity.

The role of platelet to mean platelet volume ratio in the identification of adult-onset still's disease from sepsis

OBJECTIVES: Inflammatory factors exert a significant role in the development of adult-onset Still's disease (AOSD) and sepsis. Although platelet counts and platelet parameters have long served as indicators for inflammatory diseases, their role in the differential diagnosis between adult-onset stilĺs disease and sepsis remains unclear. We designed this retrospective study to explore whether the platelet to mean platelet volume (MPV) ratio (PMR) can help to distinguish AOSD from sepsis. METHODS: A total of 110 AOSD patients and 84 sepsis patients were enrolled in the study. Seventy-three AOSD patients and 56 sepsis patients between January 2010 and June 2017 were enrolled in the test cohort to analyze PMR values, which was then validated in the validation cohort (37 AOSD patients and 28 sepsis patients between June 2017 and December 2019). RESULTS: The values of PMR were significantly higher in AOSD patients than in sepsis patients (test cohort, validation cohort, and entire cohort), In the test cohort, logistic regression analysis showed that PMR was an independent risk factor of AOSD (odds ratios [OR]: 9.22, 95% confidence interval [CI] 2.15-39.46, p=0.003). Further receiver operating characteristic curve (ROC) analysis showed that the area under the ROC curve was 0.735 (95% CI 0.631-0.839, p<0.001) for PMR alone and 0.925 (95% CI 0.869-0.980, p<0.001) for the combination of PMR and serum ferritin. Consistently, the validation cohort exhibited analogous results. CONCLUSIONS: PMR could be used as a single indicator or a complementary indicator to distinguish AOSD from sepsis.

Adult-onset Still's disease successfully treated with Chinese herbal medicine: A case report with 15-month follow-up / 中西医结合学报

Adult-onset Still's disease (AOSD) is a rare but clinically well-known, polygenic, and systemic autoinflammatory disease, which is characterized by spiking fever, evanescent skin rash, arthralgia, and sore throat. The application of non-steroidal anti-inflammatory drugs and glucocorticoids, which are first-line therapies of AOSD, is limited due to their side effects such as liver injury or disorder of blood glucose. Therefore, patients who suffer from systemic diseases in China prefer to seek help from Chinese herbal medicine (CHM), which is an important part of complementary and alternative medicine. In this case, we report a 28-year-old male badminton coach presenting with a 15-day history of fever and skin rash, accompanied by sore throat, fatigue, myalgia and chills. Additionally, hepatosplenomegaly, multiple lymphadenopathies, aminotransferase abnormality, and elevated inflammatory factor levels were observed during hospitalization. Infectious diseases, solid tumors, hematological diseases, and common autoimmune diseases were excluded. Not benefitting from antibiotic therapy, the patient was finally diagnosed with AOSD, after a careful examination, then showed rapid remission after a six-week treatment with CHM granules based on Xiaochaihu Decoction and Yinqiao Powder. After stopping the treatment, there was no relapse within a 15-month follow-up period. To the best of our knowledge, this is the first well-documented case of this successful treatment. The present case report suggests that CHM is a reliable choice for complementary and alternative therapy for AOSD, but confirming the utility of CHM for AOSD requires further support from prospective studies.

Tocilizumab for refractory adult-onset still’s disease: Report of three cases

OBJECTIVES@#To present three cases of adult-onset still’s disease (AOSD) who was initially refractory to corticosteroid therapy but were successfully treated with an interleukin-6 (IL-6) inhibitor, tocilizumab (TCZ). @*BACKGROUND@# Adult-onset Still’s Disease (AOSD) is a systemic inflammatory disorder of unknown etiology characterized by quotidian fever, evanescent rash, and arthritis/arthralgia. The pro-inflammatory cytokine interleukin (IL) – 6 has been implicated in its pathogenesis. @*CASE PRESENTATION@#Three patients (40F, 37F, and 27M) presented with quotidian fever, evanescent maculopapular rash, arthritis, anemia, leukocytosis, elevated acute phase reactants and hyperferritinemia of 3 to 4 months duration. All were diagnosed AOSD by Yamaguchi criteria after extensive work up to exclude other diagnostic possibilities. Each patient received high dose corticosteroids and 2 patients also received methotrexate (MTX) with initial improvement of symptoms. However, there was recurrence and exacerbation of clinical symptoms on tapering of steroid doses. Each patient was then given TCZ at 8 mg/kg. Within a month of the initial dose of TCZ, there was dramatic clinical and laboratory improvement, enabling rapid steroid dose tapering. @*CONCLUSION@#This series substantiates the role of IL-6 in the pathomechanisms of AOSD and demonstrates use of TCZ in the management of AOSD refractory to corticosteroids.

Rapid responses to golimumab in refractory adult-onset Stills disease: A case report and review of the literature

ABSTRACT Introduction: Adult onset Still's disease (AOSD) is a systemic inflammatory disorder of unknown etiology. AOSD is generally a mild and self-limiting disease, but it could progress to become chronic. The anemia of chronic diseases may occur in patients with acute or chronic immune activation, and is associated with the production of pro-inflammatory cytokines. Case report: A 61-year-old woman with several pharyngitis episodes, spiking fever, evanescent salmon-pink skin rash, normocytic normochromic anemia, leucocytosis, thrombocytopenia, polyarthritis, liver dysfunction, marked elevated erythrocyte sedimentation rate and C-reactive protein and, notably high ferritin levels. AOSD was diagnosed after secondary diseases were ruled out. Despite eight month on treatment with high-dose corticosteroids and methotrexate the clinical course the patient worsened, with significant synovitis, joint deformities leading to a worse quality of life and requiring help with activities of daily living. A rapid response to the anti-TNFα golimumab (50 mg/month) was observed from the third month of treatment. Conclusion: Golimumab improved anemia, serum C-reactive protein levels, polyarthritis and quality of life in a refractory AOSD.

Adult onset still’s disease: a diagnostic dilemma

Adult onset still’s disease is a rare systemic inflammatory disorder of unknown aetiology, characterized by clinical triad (high spiking fever, evanescent rash and arthritis) and biological triad with lack of serological markers as a true gold standard makes diagnosis difficulty. Here is a case of 32year old male presented with high grade fever for 2 months, joint pains and swelling for 1month rash for 3 days. O/E: pallor and B/L tender, swollen ankle and knee joints, and P/A: splenomegaly. Investigations showed-Hb%. 8 gms, neutrophilic leucocytosis with thrombocytosis, ESR:72 mm/1h, CRP elevated. ASO-titre, RA factor and Anti CCP antibodies are negative. Adult onset still’s disease is a heterogenous and rare systemic inflammatory disorder of unknown aetiology with lack of serological diagnostic modalities.

Red blood cell distribution width is useful in discriminating adult onset Still's disease and sepsis within 24 hours after hospitalization

BACKGROUND/AIMS: Red blood cell distribution width (RDW) is a value representing the heterogeneity in the size of red blood cell, and it is usually used in distinguishing types of anaemia. Recently, it was reported that it could reflect the burden of inflammation in diverse diseases and their prognosis. Hence, in this study, we investigated whether RDW may contribute to discriminating adult onset Still’s disease (AOSD) from sepsis in serious febrile patients within 24 hours after hospitalization. METHODS: We reviewed the medical records and enrolled 21 AOSD patients, 27 sepsis patients and 30 matched healthy controls. We collected at least two laboratory results of variables including RDW within 24 hours after hospitalization, and we calculated their mean values. RESULTS: Sepsis patients showed the significantly increased median white blood cell count, compared to AOSD patients (14,390.0/mm3 vs. 12,390.0/mm3 , p = 0.010). The median RDW in sepsis patients was higher than that in AOSD patients (15.0% vs. 13.3%, p = 0.001), and furthermore, the median RDW in both patient-groups was significantly higher than that in healthy controls. In contrast, the median ferritin level in sepsis patients was lower than that in AOSD patients (544.0 mg/dL vs. 3,756.6 mg/dL, p = 0.001). In multivariate analysis, RDW ≥ 14.8% (odds ratio, 17.549) and ferritin < 2,251.0 mg/dL (odds ratio, 32.414) independently suggested sepsis more than AOSD in patients initially presenting with fever requiring hospitalization. CONCLUSIONS: RDW might be a rapid and helpful marker for a differential diagnosis between AOSD from sepsis at an early phase.

Adult-onset Still's Disease as the First Manifestation of Cerebral Infarction: a Case Report

Adult-onset Still's disease (AOSD) is a rare systemic febrile disorder of unknown etiology. AOSD is characterized by spiking fever, arthralgia, sore throat, skin rash, and multi-organ involvement but is difficult to diagnose due to the lack of specific clinical features. AOSD is most frequently observed among young adults. We describe the case of an 18-year-old male patient with multiple cerebral infarction who was diagnosed with AOSD based on the clinical features observed during rehabilitation treatment after the diagnosis of ischemic stroke. Clinical symptoms of the patient was controlled with steroid therapy. If cerebral infarction is accompanied by unusual clinical features as non-infectious fever, rash, and arthralgia, AOSD should be considered in young stroke patient.

Enfermedad de Still del Adulto, a propósito de un caso / Still's disease, a clinical case

La enfermedad de Still del Adulto es una variante sistémica del universo llamado "artritis idiopática juvenil", cuya diferencia es la edad de aparición, recibiendo este nombre cuando el cuadro se manifiesta en personas mayores de 15 años. Es una enfermedad autoinflamatoria caracterizada por fiebre intermitente, artritis, rash evanescente y linfadenopatías, asociado a manifestaciones de compromiso sistémico. Es una patología de baja prevalencia, pero es importante considerarla como uno de los principales diagnósticos etiológicos de la fiebre de origen desconocido.

Adult-onset Still's disease is a systemic variant of Still's disease distinguished from juvenile idiopathic arthritis by its onset age of over 15. It is an auto-inflammatory disease characterized by intermittent fever, arthritis, short-lived rash and lymphadenopathies. It has low prevalence but is important to consider as one of the principle etiological diagnoses of fever of unknown origin.

Delta Neutrophil Index as an Early Marker for Differential Diagnosis of Adult-Onset Still's Disease and Sepsis

PURPOSE: To investigate clinical implications of delta neutrophil index (DNI) to discriminate adult onset Still's disease (AOSD) from sepsis. MATERIALS AND METHODS: We reviewed the medical records of 13 patients with AOSD and 33 gender and age-matched patients with sepsis. In all subjects, microbial tests were performed to exclude or confirm sepsis. All laboratory data were measured two or three times during the first 3 days and represented by their mean levels. DNI was measured automatically by ADVIA 2120 for the first 3 days. RESULTS: There were no significant differences in white blood cell counts, neutrophil proportion, erythrocyte sedimentation rate and C-reactive protein between two groups. AOSD patients had notably lower DNI than sepsis patients regardless of the presence of bacteremia or not. However, both DNI and ferritin were not significant independent factors for predicting sepsis in the multivariate logistic regression analysis. Meanwhile, the area under the receiver operating characteristic curve (AUROC) of DNI was slightly higher than that of ferritin. When we set DNI of 2.75% as the cut-off value for predicting sepsis, 11 (84.6%) of AOSD patients had a DNI value below 2.75% and 2 (15.4%) of them had a DNI over 2.75% (relative risk for sepsis 176). CONCLUSION: We suggest that DNI may be a useful marker for differential diagnosis of AOSD from sepsis in the early phase as supplementary to ferritin.

A Case of Adult Onset Still's Disease with Severe Pneumonitis Treated with Anakinra / 대한내과학회지

Adult onset Still's disease (AOSD) is a systemic autoinflammatory disorder that presents with recurrent fever, extreme fatigue, and joint pain. Pulmonary involvement is not uncommon and, although rare, severe pneumonitis can progress to respiratory failure. Still's disease-associated pneumonitis is generally treated with immunosuppressive agents, but improvement in our understanding of systemic inflammatory processes led us to explore alternative agents. Anakinra is an interleukin-1 receptor antagonist used to treat autoinflammatory disorders resistant to immunosuppressive therapy. Several case reports have demonstrated efficacy of anakinra in treating AOSD, but its relevance in cases complicated with severe pneumonitis has not been examined. Our patient's disease activity was not controlled with systemic steroids and cyclophosphamide. Treatment with anakinra led to a dramatic clinical response. This is the first reported case of AOSD with severe pneumonitis refractory to conventional therapy successfully treated with anakinra.
