Fiebre de origen desconocido como forma de presentación de la enfermedad de Still del adulto

Introducción: La enfermedad de Still del adulto es una enfermedad reumática, inflamatoria, sistémica y crónica cuya prevalencia en la población caucásica se estima en 1 caso por cada 100 000 adultos Objetivo: Presentar un paciente adulto joven, con una fiebre de origen desconocido como forma de presentación de la enfermedad de Still del adulto. Caso clínico: Paciente de 29 años de edad con antecedente de fiebre reumática, con un ingreso hospitalario anterior; que presentó un cuadro febril no infeccioso, de 50 días de duración, al cual no se le determinó la causa. Un año después reapareció la fiebre, de similares características, asociada a poliartralgia, hepatoesplenomegalia, anemia, hiperferritinemia, neutrofilia, factor reumatoideo negativo y se constató un cuadro de pericarditis durante el ingreso. Se realizó el diagnóstico de enfermedad de Still del adulto, por exclusión. Se inició tratamiento con esteroides, desapareció la fiebre en las primeras 24 horas y el paciente tuvo una evolución favorable. Conclusiones: La enfermedad de Still del adulto puede presentarse como una fiebre de origen desconocido y se diagnostica por exclusión, ya que no existen manifestaciones clínicas ni pruebas de laboratorio, patognomónicas. La hiperferritinemia es útil para la sospecha diagnóstica.

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.

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.

Adult-onset idiopathic hypogonadotropic hypogonadism: An evaluation of the diagnosis and treatment for three cases / 中华内分泌代谢杂志

Objective:To investigate the clinical characteristics and offer diagnostic and therapeutic approaches for adult-onset idiopathic hypogonadotropic hypogonadism(AIHH).Methods:Clinical, laboratory, and imaging data, as well as follow-up information, of three male patients diagnosed with AIHH at the Department of Endocrinology and Metabolism of Nanfang Hospital, Southern Medical University, were systematically reviewed and analyzed.Results:All three patients were male, with a median age of 39 years(range, 22 to 40). Two patients reported symptoms of enlarged breasts and reduced sexual function, while one case solely reported a decline in sexual function. Physical examination showed that the median length of the penis was 6 cm(range, 5 to 6 cm), and the bilateral testicular volume was 7.96 mL(4.70-8.82 mL). Basal hormone levels at the time of initial visit to our hospital as follows: the median testosterone level was 0.32 ng/mL(0.24-2.96 ng/mL), median follicle stimulating hormone(FSH) level was 0.56 mIU/mL(0.1-0.75 mIU/mL), and the median luteinizing hormone(LH) level was 0.69 mIU/mL(0.1-1.03 mIU/mL). The levels of other hormones secreted by the anterior pituitary gland were normal. Hypothalamic-pituitary magnetic resonance imaging(MRI) showed that 1 patient had a pituitary microadenoma. Three patients were treated with pulsatile GnRH or gonadotropins, one of which had hypothalamic-pituitary-gonadal(HPG) axis function reversal after GnRH pulse pump therapy and lasted for 1 year, but then still had irreversible reduction.Conclusion:AIHH is marked by adult-onset disease and idiopathic hypogonadism. Enhancing fertility remains a critical requirement for these patients. Pulsatile GnRH treatment or gonadotropin therapy, as viable treatments, exhibit therapeutic effects, albeit with occasional fluctuations. Therefore, the emphasis lies in the timely consideration of fertility preservation.

Hiperferritinemia: Experiencia de un Centro Universitario en Chile / Hyperferritinemia in a Chilean Academic Healthcare Network: A Retrospective Study

INTRODUCTION: The distribution of causes of hyperferritinemia in international series is heterogeneous. Also, the association between ferritin and prognosis is controversial. This study aims to describe the diagnosis associated with hyperferritinemia in a retrospective cohort at an academic healthcare network in Chile. METHODS: A retrospective review of adult patients admitted to our academic medical center from June 2014 to February 2017 with ferritin ≥3,000 ng/mL. All patients were classified into nine diagnostic categories. Then, the association between ferritin level and disease category, as well as mortality, was evaluated. RESULTS: Ninety-nine patients were identified. The mean age was 50.8 ± 19.9 years, 54.5% were men. The most frequent categories were "inflammatory and autoimmune diseases" (21.2%) and "hematological malignancies" (19.2%). The average ferritin was 10,539 ± 13,016.9 ng/mL, while the higher mean was 16,707 ng/mL in the "inflammatory and autoimmune diseases" category. There was a statistically significant association between the ferritin value and age but not between ferritin and diagnostic categories. In the group over 50, hematologic neoplasms (19%) and infections (19%) were more frequent. In those under 50, inflammatory and autoimmune diseases were more frequent (26.8%). There was no association between the ferritin level and mortality at 1, 3, and 12 months. CONCLUSIONS: The most frequent categories were "inflammatory and autoimmune diseases" and "hematological malignancies", but ferritin level was similar in both. Further research could validate a prognostic role.

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.

Recommendations of diagnosis and treatment of adult-onset Still′s disease in China / 中华内科杂志

Adult-onset Still′s disease (AOSD) is a rare systemic autoinflammatory disorder. In China, standardized diagnosis and treatment for AOSD is insufficient. Based on the evidence from China and other countries, Chinese Rheumatology Association developed standardization of diagnosis and treatment of AOSD in China. The purpose is to standardize the methods for diagnosis of AOSD, treatment strategies, and reduce misdiagnosis, missed diagnosis and irreversible damage.

A Young Woman with Leukoencephalopathy and Significant Corpus Callosum Atrophy / 罕见病研究

Adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP) is a rare autosomal-dominant progressive leukodystrophy, caused by mutations of colony stimulating factor-1 receptor (CSF1R) gene. Age of onset is usually between 40 and 50 years old and the clinical presentations include dementia, apraxia, behavioral changes, pyramidal and extrapyramidal signs. Varying clinical manifestations have led to misdiagnoses. Magnetic resonance imaging (MRI) typically reveals white matter changes with T2-Flair/DWI hyperintensity and atrophy especially for thinning of the corpus callosum. Here, we report a young woman experiencing hypomnesia for 2 years with lower extremities weakness and rigidity for 1 month. Considering the evidence of clinical manifestations, imaging and genetic test, this patient was diagnosed with ALSP.

Case Report of A Rare Case of Adult-Onset Multi-site Lichen Striatus in an Adult

Summary@#Lichen striatus (LS) is a rare self-limiting inflammatory dermatosis characterized by Blaschkoid distribution. We report a 34-year-old woman with a 1-year history of asymptomatic unilateral rashes on her left trunk and limbs. Physical examination revealed light to dark brown papules, macules, patches and plaques with some erythematous areas in a Blaschkoid pattern with proven skin biopsy as well. Patient received potent topical corticosteroid therapy which resulted in the resolution of the lesion. This case report highlights two rare aspect of lichen striatus; involvement of multiple sites and late adult-onset. It is also a reminder that lichen striatus should be included in the differentials of acquired linear dermatoses.

Adult-onset Still's disease after ChAdOx1 nCoV-19 vaccine: a possible association

ABSTRACT With emergent Sars-Cov-2, a highly transmissive virus that caused millions of deaths worldwide, the development of vaccines became urgent to combat COVID-19. Although rare, important adverse effects had been described in a hypothetical scenario of immune system overstimulation or overreaction. Still's disease is a rare inflammatory syndrome of unknown etiology. It manifests as a cytokine storm, mainly IL-18 and IL-1β, and presents itself with fever spikes, joint pain, maculopapular evanescent salmon-pink skin rash, and sore throat, among other symptoms. Here, we report a case of a 44-year-old healthy male who developed adult-onset Still's disease (AOSD) with atypical symptoms after both doses of ChAdOx1 nCoV-19 vaccine with 3 months of dose interval. The medical team suspected Still's disease and started prednisone 1 mg/kg (40mg). The next day the patient showed a marked improvement in articular and chest pains and had no other fever episodes. Therefore, he was discharged to continue the treatment in outpatient care. On the six-month follow-up, the patient was free of complaints, and the progressive corticoid withdrawal plan was already finished.
