Miopericarditis, una manifestación inicial poco común de la enfermedad de Still del adulto. Reporte de caso / Myopericarditis, a rare initial manifestation of adult Still's disease. Case report

RESUMEN La enfermedad de Still es un desorden inflamatorio infrecuente, con múltiples formas de presentación; sin embargo, el debut con miocarditis o pericarditis es aún menos común (prevalencia del 7%). Se presenta el caso de un hombre de 30 años, previamente sano, que consultó por dolor torácico. Durante su evolución clínica fue diagnosticado con miopericarditis, se indagaron diversas etiologías, pero luego de múltiples estudios se diagnosticó enfermedad de Still del adulto. Se instauró tratamiento con corticoesteroides, el cual tuvo una adecuada respuesta.

A B S T R A C T Adult-onset Still's disease is a rare inflammatory disorder with multiple forms of manifestation; however, the onset with myocarditis or pericarditis is even less common (7% prevalence). Herein, we present a case of a previously healthy 30-year-old man, who consulted for chest pain. During his clinical evolution, he was diagnosed with myopericarditis. Various aetiologies were evaluated and after multiple studies adult-onset Still's disease was diagnosed. Treatment with corticosteroids was established evidencing an adequate response.

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.

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

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-1ß, 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.

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.

Role of mean platelet volume in differential diagnosis of adult-onset Still's disease and sepsis

SUMMARY OBJECTIVES: Mean platelet volume is a simple biomarker for inflammatory disease. The purpose of this study is to evaluate the role of mean platelet volume in distinguishing adult-onset Still's disease from sepsis. METHODS: We retrospectively selected 68 patients with adult-onset Still's disease and 55 patients with sepsis between January 2015 and December 2019. Related laboratory data were collected and analyzed. RESULTS: There were no significant differences in white blood cell counts, neutrophils, lymphocytes, and C-reactive protein between adult-onset Still's disease group and sepsis group. However, patients in adult-onset Still's disease group showed higher ferritin and platelets and lower mean platelet volume and platelet distribution width than those in sepsis group (p<0.01 for both). Receiver operating characteristic curve analysis was performed to distinguish adult-onset Still's disease and sepsis. The area under the curve of mean platelet volume was 0.761 (95%CI 0.673-0.849), with a sensitivity of 79.1%, a specificity of 63.3%, and a cutoff value of 10.9 fL. In contrast, the area under the curve of combined ferritin and mean platelet volume was 0.90l (95%CI 0.837-0.965), with higher sensitivity (82.8%) and specificity (96.2%). Therefore, mean platelet volume could be used as a supplementary indicator to distinguish adult-onset Still's disease from sepsis. CONCLUSION: We suggest that mean platelet volume could be used as a supplementary biomarker for differential diagnosis of adult-onset Still's disease and sepsis in addition to ferritin.

Adult onset still's disease (aosd): a rare condition with a classic clinical presentation. case report

ABSTRACT Introduction: Adult Onset Still's Disease (AOSD) is a rare systemic inflammatory disease of unclear etiology, with low incidence and prevalence among the general population. AOSD is a common cause of fever of unknown origin (FUO) in up to 20% of cases. Due to the scarce knowledge about this disease and its diagnosis, it is usually unrecognized in the differential diagnoses, worsening the prognosis and increasing complications in some patients. Case presentation: This is the case of a 32-year-old female patient with prolonged febrile illness, who did not respond to the antimicrobial treatments previously established. She was diagnosed with AOSD according to the Yamaguchi criteria after an extensive exclusion process. She was treated with first-line treatment with corticosteroids, achieving satisfactory results Conclusions: The diagnosis of AOSD is an exhaustive process. Regardless of the availability of cutting-edge diagnostic tools, the medical history of the patient and an adequate physical examination are the most important aspects to consider.

RESUMEN Introducción. La enfermedad de Still del adulto (ESA) es una enfermedad inflamatoria sistémica de baja incidencia y prevalencia en población general y cuya etiología aún no es clara. La ESA puede causar fiebre de origen desconocido hasta en el 20% de los casos, pero suele pasar inadvertida dentro de los diagnósticos diferenciales iniciales debido a su desconocimiento, lo que empeora el pronóstico y aumenta las complicaciones en los pacientes. Presentación del caso. Paciente femenina de 32 años con síndrome febril prolongado que no respondía a tratamientos antimicrobianos instaurados previamente y en quien, finalmente, se diagnosticó ESA aplicando los criterios clasificatorios de Yamaguchi. La mujer recibió tratamiento de primera línea con corticosteroides y obtuvo buenos resultados. Conclusiones. La ESA requiere un exhaustivo proceso para su diagnóstico, en el cual, a pesar de la disponibilidad de herramientas diagnósticas avanzadas, la verificación de la historia clínica y la realización de un adecuado examen físico son los aspectos más importantes a tener en cuenta.

Resumen Introducción. La enfermedad de Still del adulto (ESA) es una condición médica poco frecuente que puede presentar complicaciones graves; sin embargo, aún no se conocen con claridad sus factores de riesgo, sus factores pronósticos, ni los aspectos asociados a las recaídas y a la refractariedad a esteroides en individuos con esta condición. Objetivos. Describir el comportamiento clínico de la ESA y determinar los factores asociados a la refractariedad a esteroides, a recaídas y a complicaciones en pacientes con esta enfermedad. Materiales y métodos. Estudio retrospectivo de cohortes que incluyó 45 pacientes diagnosticados con ESA entre enero de 2007 y enero de 2017 en 2 hospitales de referencia. Se presentan medidas de resumen. Se realizaron dos análisis de regresión logística para identificar posibles factores que expliquen la refractariedad a esteroides, las recaídas y el desarrollo de complicaciones en la población de estudio. Resultados. La edad promedio de los participantes fue 42.13±15.8 años. De los 45 pacientes incluidos, 23 (51.1%) eran mujeres, a 42 (93.3%) se le prescribieron esteroides, y, de estos, 13 (32%) se consideraron refractarios a esteroides. Se presentaron complicaciones en 12 (26.7%) individuos y su frecuencia fue mayor en pacientes con temperatura máxima >39°C. Finalmente, 33 (73.3%) pacientes tuvieron un seguimiento mayor a 1 año, de los cuales, 17 (37.8%) presentaron recaídas, las cuales fueron más frecuentes en individuos refractarios a esteroides o con esplenomegalia. Conclusión. Los pacientes que recibieron cualquier tipo de terapia biológica fueron más refractarios a esteroides; por su parte, la refractariedad a esteroides y la esplenomegalia se asociaron a un mayor número de recaídas, y la temperatura >39°C se asoció a al desarrollo de complicaciones.

Abstract Introduction: Adult Still disease (ASD) is a rare disorder that can lead to serious complications; however, risk factors associated with the development of this disease, its prognostic factors, and aspects related to relapse and steroids refractoriness in individuals with this condition are not yet clearly known. Objectives: To describe the clinical behavior of ASD and determine factors associated with steroid refractoriness, relapse, and complications in patients with this condition. Materials and methods: A retrospective cohort study was conducted in 45 patients diagnosed with ASD between January 2007 and January 2017 in 2 reference hospitals. Summary statistics are presented. In addition, two logistic regression analysis were conducted in order to identify possible factors explaining steroid refractoriness, relapses, and the development of complications in the study population. Results: Participants' average age was 42.13 ± 15.8 years. Out of the 45 patients, 23 (51.1%) were women, 42 (93.3%) were prescribed steroids, and of these, 13 (32%) were considered as steroid refractory. Complications were observed in 12 individuals (26.7%), and their frequency was higher in patients whose maximum body temperature was higher than 39°C. Finally, 33 (73.3% patients had a follow-up greater than 1 year, of which 17 (37.8%) suffered relapses; in addition, relapses were more frequent in patients who were steroid refractory or those with splenomegaly. Conclusion: Patients who were prescribed any type of biological therapy were more steroid refractory. On the other hand, steroid refractoriness and splenomegaly were associated with a higher frequency of relapses, while having a body temperature >39°C was associated with developing complications.

Enfermedad de Still del adulto. Presentación de un caso / Still´s disease in adults. Case presentation

La enfermedad de Still del adulto es una entidad de posible origen autoinmune, de etología desconocida y presentación infrecuente. Se caracteriza por fiebre alta, artritis, leucocitosis neutrofílica y exantema evanescente. Los valores de ferritina sérica por encima de 3 000 ng/mL son de gran valor para establecer el diagnóstico. En el presente artículo se describe el caso de un paciente de 28 años de edad, masculino, con un síndrome febril crónico, erupción cutánea, odinofagia y artritis. Se realizaron exámenes complementarios mediante los que se demostró la existencia de leucocitosis, elevación de los niveles de enzimas hepáticas y de ferritina sérica. La baja incidencia de la enfermedad, su complicada forma de presentación, así como la inexistencia de algún complementario confirmatorio para su diagnóstico, motivó a los autores a describir un paciente con enfermedad de Still del adulto. 

Still´s disease in adults is an entity with a possible autoimmune origin, of unknown etiology and infrequent presentation. It is characterized by high fever, netrophylic leukocytosis, and transient exanthema. The values of seric ferritin over 3 000 ng/mL are of great value to determine the diagnosis. It is described the case of a 28 year old male patient with chronic febrile syndrome, cutaneous rash, odynophagia and arthritis. Laboratory tests were performed which showed leukocytosis, high level of hepatic enzymes and seric ferritin. The low incidence of this disease, its complicated form of presentation, so as the non- existence of any confirming test for its diagnosis, motivated the authors to describe a patient with Still´s disease of the adult.

Oral mucosa lesions as atypical manifestation of adult-onset Still´s disease

Abstract: Adult-onset Still's disease is a systemic inflammatory disorder of unknown etiology, characterized by skin rash, spiking fever, arthralgias or arthritis, and leukocytosis. The typical skin rash is evanescent, salmon-pink, nonpruritic and maculopapular, predominantly on the extremities. It is considered one of the major Yamaguchi's criteria in adult-onset Still's disease. However, atypical skin lesions are also described. Here, a 61-year-old woman with sore throat, spiking fever, polyarthritis and evanescent salmon-pink nonpruritic maculopapular skin rash on the extremities was diagnosed with adult-onset Still's disease. In addition, atypical brown macules on oral mucosa, localized on the inner lips and tongue were also observed. Biopsy revealed a neutrophilic infiltrate. Despite treatment and improvement of the adult-onset Still's disease, the atypical oral mucosal lesions persisted.

Skin symptoms as diagnostic clue for autoinflammatory diseases

ABSTRACT Autoinflammatory disorders are immune-mediated diseases with increased production of inflammatory cytokines and absence of detectable autoantibodies. They course with recurrent episodes of systemic inflammation and fever is the most common symptom. Cutaneous manifestations are prevalent and important to diagnosis and early treatment of the syndromes. The purpose of this review is to emphasize to dermatologists the skin symptoms present in these syndromes in order to provide their early diagnosis.

Adult onset Still disease: A rare condition. Clinical experience with 17 cases / Una patología poco frecuente: la enfermedad de Still del adulto. Experiencia clínica con 17 casos

OBJECTIVE: To present current clinical experience and the clinical outcomes in the management of patients with adult Still disease. MATERIALS AND METHODS: A retrospective study of a case series was conducted on of 17 cases diagnosed with adult Still disease during a period between 2009 and 2014 in 2 tertiary hospitals in Santiago de Cali. RESULTS: Of the 17 cases diagnosed and treated, it was found that 50% of patients had an elevated ferritin five times its normal value, being useful in the diagnosis. Less than 50% of cases were under 40 years, and about 50% of the population required combined treatment, with two patients requiringbiological therapy to control their symptoms. Yamaguchi criteria were used for diagnostic correlation. CONCLUSIONS: Adult Still's disease is a rare disease that requires a high index of suspicion, but it must be a disease to rule out, and it always requires management generally combined with schemes to improve the quality of life of patients.

OBJETIVO: Dar a conocer la experiencia clínica en el mundo real y los resultados clínicos del manejo de los pacientes con enfermedad de Still del adulto. MATERIALES Y MÉTODOS: Se realiza un estudio retrospectivo de serie de casos, de 17 casos con diagnóstico de enfermedad de Still del adulto, en 2 clínicas de nivel 3 de Santiago de Cali, Colombia, en el periodo comprendido entre 2009 y 2014. RESULTADOS: De los 17 casos diagnosticados y tratados se encontró que en el 50% de los pacientes había una elevación de ferritina de 5 veces su valor normal, siendo útil en el diagnóstico, menos del 50% de los casos fueron en menores de 40 anos, alrededor del 50% de la población requirió tratamiento combinado y 2 pacientes requirieron terapia biológica para el control de sus síntomas. Se usaron los criterios de Yamaguchi para la correlación diagnóstica. CONCLUSIONES: de descarte y, generalmente, siempre requiere manejo con esquemas combinados para mejorar la calidad de vida del paciente.
