ABSTRACT

Durante la pandemia por COVID-19 se observaron diversas reacciones adversas a fármacos. Esto pudo haber estado relacionado con una mayor susceptibilidad inmunológica de los pacientes con SARS-CoV-2 a presentar este tipo de cuadros, así como también con la exposición a múltiples medicamentos utilizados en su tratamiento. Comunicamos el caso de un paciente con una infección respiratoria grave por COVID-19, que presentó 2 reacciones adversas graves a fármacos en un período corto de tiempo. (AU)


During the COVID-19 pandemic, various adverse drug reactions were observed. This could have been related to a greater immunological susceptibility of patients with SARS-CoV-2 to present this type of symptoms, as well as exposure to multiple drugs used in their treatment. We report the case of a patient with a severe respiratory infection due to COVID-19, who presented 2 serious adverse drug reactions associated with paracetamol in a short period of time. (AU)

ABSTRACT

En Uruguay, la pandemia por SARS-CoV-2 ha generado menos afectación en pacientes de la edad pediátrica, aumentando el número de casos positivos en este grupo etario de forma proporcional al aumento de la circulación del virus. La forma de presentación es generalmente asintomática o con síntomas respiratorios leves a moderados. El síndrome inflamatorio multisistémico postinfección por SARS-CoV-2 (SIM-C) ha sido descrito como una de las principales complicaciones postinfección. Se describe el primer caso de un paciente con SIM-C en la ciudad de Paysandú, Uruguay. Se trata de un escolar de 6 años que cursó una infección por SARS-CoV-2 un mes previo. Se presenta con un cuadro febril de 4 días de evolución asociado a lesiones de piel e inyección conjuntival y odinofagia, con parámetros inflamatorios elevados y afectación cardiológica. Se traslada a CTI local con buena evolución posterior. El alto índice de sospecha de SIM-C mejora el diagnóstico y en consecuencia la morbimortalidad de la enfermedad.


Summary: In Uruguay, the SARS-CoV-2 pandemic has affected the pediatric population less and the number of positive cases in this age group has increased proportionally to the rise of the virus circulation. The presentation is generally asymptomatic or with mild to moderate respiratory symptoms. Post-Infection Multisystem Inflammatory Syndrome by SARS-CoV-2 (MIS-C) has been described as one of the main post-infection complications. We describe the first case of a patient with MIS-C in the city of Paysandú, Uruguay. It is a 6-year-old schoolboy who had had a SARS-CoV-2 infection a month earlier. He showed a 4-day history of fever associated with skin lesions and conjunctival injection and odynophagia, with high inflammatory parameters and cardiac involvement. He was transferred to a local ICU and had a good subsequent evolution. The high index of suspicion of MIS-C improves the diagnosis and consequently the morbidity and mortality rates of the disease.


No Uruguai, a pandemia de SARS-CoV-2 gerou menos afetação em pacientes pediátricos, e o número de casos positivos nessa faixa etária aumentou proporcionalmente ao aumento da circulação do vírus. A forma de apresentação é geralmente assintomática ou com sintomas respiratórios leves a moderados. A Síndrome Inflamatória Multissistêmica Pós-Infecção por SARS-CoV-2 (MIS-C) tem sido descrita como uma das principais complicações pós-infecção. Descreve-se o primeiro caso de paciente com MIS-C na cidade de Paysandú, Uruguai. Ele é um estudante de 6 anos de idade que tinha tido uma infecção por SARS-CoV-2 um mês antes. Apresentou história de febre de 4 dias associada a lesões cutâneas e hiperemia conjuntival e odinofagia, com parâmetros inflamatórios elevados e envolvimento cardiológico. Foi transferido para uma UTI local com boa evolução posterior. O alto índice de suspeita de MIS-C melhora o diagnóstico e, consequentemente, a morbimortalidade da doença.

ABSTRACT

En abril de 2020, durante el pico de la pandemia COVID-19 producida por el coronavirus emergente SARS-CoV-2, en el Reino Unido se comunicaron casos de shock hiperinflamatorio de características similares a la enfermedad de Kawasaki y el síndrome de shock tóxico en un grupo de ocho niños. El Royal College of Pediatrics and Child Health lo denominó síndrome inflamatorio multisistémico pediátrico temporalmente asociado con COVID-19 (SIM-C). Actualmente, el SIM-C es una enfermedad infrecuente, solapada con otras entidades, que requiere una alta sospecha clínica para identificarlo oportunamente. El síndrome inflamatorio multisistémico temporal asociado con SARS-CoV-2 pediátrico (PIMST) es una nueva entidad clínica con un amplio espectro de presentación postexposición al virus, inmunomediado con hiperinflamación y activación de una tormenta de citoquinas. Ocurre típicamente entre la segunda y cuarta semana de evolución. Se describen marcadores de inflamación característicamente elevados, como son la ferritina, proteína C reactiva (PCR), velocidad de eritrosedimentación (VES), lactato deshidrogenasa y dímero-D, asociados a neutropenia, linfopenia y anemia. La Organización Mundial de la Salud (OMS) define: caso a menores de 19 años con fiebre ≥3 días, marcadores inflamatorios elevados, evidencia de infección por SARS-CoV-2 y ninguna otra etiología microbiana; con afectación de al menos dos sistemas: dermatológico (rash, conjuntivitis no exudativa, inflamación mucocutánea), hemodinámico (hipotensión, shock), cardíaco (disfunción de miocardio, pericardio, valvular o coronario), hematológico (coagulopatía), digestivo (vómitos, diarrea, dolor abdominal). Considerando la gravedad de esta nueva entidad, es necesario el reconocimiento oportuno y referencia temprana para atención especiaizada y tratamiento oportuno.


Summary: In April 2020, during the peak of the COVID-19 pandemic caused by the emerging coronavirus SARS-CoV-2, 8 children reported cases of hyperinflammatory toxic shock with characteristics similar to Kawasaki disease and syndrome in the United Kingdom. The Royal College of Pediatrics and Child Health has called it pediatric Multisystem Inflammatory Syndrome (MIS) temporally associated with COVID-19. Currently, MIS-C is a rare disease, overlapping with other conditions, which requires a high clinical suspicion for its timely identification. Pediatric SARS-CoV-2-associated temporary multisystem inflammatory syndrome (TMIS-C) is a new clinical entity with a broad spectrum of presentation after exposure to the virus, immune-mediated with hyperinflammation and activation of a cytokine storm. It typically occurs between the 2nd to 4th week of evolution. Characteristically elevated markers of inflammation are described, such as ferritin, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), lactate dehydrogenase and D-dimer, associated with neutropenia, lymphopenia and anemia. The World Health Organization (WHO) defines it as: a case under 19 years of age with fever ≥ 3 days, elevated inflammatory markers, evidence of SARS-CoV-2 infection and no other microbial etiology; with involvement of at least 2 systems: dermatological (rash, non-exudative conjunctivitis, mucocutaneous inflammation), hemodynamic (hypotension, shock), cardiac (myocardial, pericardial, valvular, or coronary dysfunction), hematologic (coagulopathy), digestive (vomiting, diarrhea, abdominal pain) Considering the seriousness of this new entity, timely recognition and early referral for specialized care and timely treatment are key.


No mês de abril de 2020, durante o pico da pandemia de COVID-19 causada pelo emergente coronavírus SARS-CoV-2, 8 casos de crianças com choque hiperinflamatório com características semelhantes à doença e síndrome de Kawasaki foram relatados no Reino Unido. O Royal College of Pediatrics and Child Health nomeou-o como síndrome inflamatória multissistêmica pediátrica (MIS) temporariamente associada ao COVID-19. Atualmente, o SIM-C é uma doença rara, sobrepondo-se a outras entidades, o que requer alta suspeição clínica para sua identificação oportuna. A síndrome inflamatória multissistêmica temporária associada ao SARS-CoV-2 pediátrico (SIMT) é uma nova entidade clínica com amplo espectro de apresentação após exposição ao vírus, imunomediada com hiperinflamação e ativação de uma tempestade de citocinas. Geralmente ocorre entre a 2ª a 4ª semana de evolução. São descritos marcadores de inflamação caracteristicamente elevados, como ferritina, proteína C reativa (PCR), velocidade de hemossedimentação (VHS), lactato desidrogenase e D-dímero, associados a neutropenia, linfopenia e anemia. A Organização Mundial da Saúde (OMS) a define como: caso de menor de 19 anos com febre ≥ 3 dias, marcadores inflamatórios elevados, evidência de infecção por SARS-CoV-2 e nenhuma outra etiologia microbiana; com envolvimento de pelo menos 2 sistemas: dermatológico (erupção cutânea, conjuntivite não exsudativa, inflamação mucocutânea), hemodinâmica (hipotensão, choque), cardíaca (disfunção miocárdica, pericárdica, valvar ou coronariana), hematológica (coagulopatia), digestiva (vômitos, diarreia, dor abdominal) Considerando a gravidade dessa nova entidade, é necessário o reconhecimento oportuno e encaminhamento precoce para atendimento especializado e tratamento oportuno.

ABSTRACT

El diagnóstico diferencial entre la enfermedad de injerto contra huésped aguda grave (estadio IV) y la necrólisis epidérmica tóxica pude resultar difícil en el contexto de un paciente trasplantado, ya que ambas tienen presentaciones clínicas similares. Sin embargo, la distinción entre ellas es fundamental porque ocasionan una gran morbimortalidad, y su manejo y pronóstico difieren. Algunas pequeñas diferencias clínicas e histopatológicas son de gran ayuda para el diagnóstico diferencial y el dermatólogo deberá reconocerlas para tomar una conducta correcta y oportuna. Se comunica el caso de un paciente que presentó ampollas y epidermólisis después del trasplante de células hematopoyéticas y en el que se planteó la dificultad diagnóstica para diferenciar entre ambas afecciones.


The differental diagnosis between severe graft-versus-host disease (stage IV) and toxic epidermal necrolysis can be difficult in the context of a transplant patient, since both conditions have similar clinical presentations. However, the distinction between these two entities is critical because they produce great morbidity and mortality and their management and prognosis differ. Some small clinical and histopathological differences are of great help for the differential diagnosis, and the dermatologist must recognize them in order to take a correct and timely conduct. We present the case of a patient who developed blisters and epidermolysis after hematopoietic cell transplantation, and in whom the diagnostic difficulty to differentiate between the two entities was raised.

ABSTRACT

El pioderma gangrenoso ampollar es una variedad infrecuente de pioderma gangrenoso, que se asocia en el 50-70% de los casos con trastornos oncohematológicos. Se comunica el caso de una paciente de 59 años, que consultó por fiebre y ampollas purpúricas de rápida progresión, con compromiso cutáneo mucoso. Con sospecha de una enfermedad neutrofílica, ampollar, o infección por gérmenes oportunistas, se realizó biopsia de piel para estudio histopatológico, inmunofluorescencia directa y cultivo. Los cultivos y la inmunofluorescencia directa fueron negativos, y la anatomía patológica reveló un denso infiltrado inflamatorio con predominio neutrofílico en dermis. Ante el diagnóstico de pioderma gangrenoso ampollar, se realizó una punción-aspiración de médula ósea cuyo resultado fue compatible con leucemia mieloide aguda. Se instauró tratamiento con corticosteroides sistémicos, a pesar de lo cual la paciente evolucionó desfavorablemente y falleció a los 15 días de su ingreso hospitalario. Este caso ilustra la asociación de esta enfermedad cutánea con trastornos oncohematológicos y el mal pronóstico que esto implica a corto plazo. (AU)


Bullous pyoderma gangrenosum is an infrequent type of pyoderma gangrenosum, associated with onco hematological diseases in 50-70% of cases. We present the case of a 59-year-old patient with fever and mucocutaneous hemorrhagic bullous of rapid progression. A biopsy for histopathology, direct immunofluorescence (DIF) and skin culture was made, considering the possibility of neutrophilic dermatoses, bullous dermatosis or an opportunistic infection. The results of both the culture and the DIF were negative. The histopathological examination of the specimen revealed a dense dermal polymorphic infiltrate composed primarily of neutrophils. Considering bullous pyoderma gangrenosum as a potential diagnosis, a bone-marrow biopsy was performed. This study revealed an acute myeloid leukemia. Although systemic corticosteroid therapy was begun, the patient presented an unfavorable evolution that led to her death 15 days after her admission at the hospital. This case shows the association between bullous pyoderma gangrenosum and onco hematological diseases. In addition, it highlights the poor prognosis related to these diseases in the short term. (AU)

ABSTRACT

Abstract Introduction: Glucocorticoids are considered the first-line therapy for sudden sensorineural hearing loss. But there is currently no consensus on administering them as a single dose versus multiple divided daily doses. Objective: We aim to evaluate the treatment outcome of sudden sensorineural hearing loss between a single-dose and multiple divided daily doses of steroid treatment. Methods: A total of 94 patients who were diagnosed and treated for sudden sensorineural hearing loss and followed up for more than three months were reviewed retrospectively. Patients were divided into single-dose and multiple divided-dose groups, based on their medication regimens. Hearing thresholds were repeatedly measured: on the initial visit and 1 week, 1 month, and 3 months after the initial treatment. Treatment outcomes were analyzed by comparing hearing recovery rates and post-treatment audiometric changes. Results: The hearing threshold was significantly reduced at three months post-treatment in both groups. The hearing recovery rate of the single-dose group was significantly higher than that of the multiple divided-dose groups. Audiometric changes showed no statistical difference either in pure tone threshold or speech discrimination. Conclusion: When oral steroids are indicated for sudden sensorineural hearing loss, both a single dose and multiple divided doses can be effective for treatment and have comparable results. However, the single-dose regimen seems to be more efficacious than the divided-dose regimen.


Resumo Introdução: Os glicocorticoides são considerados terapia de primeira linha para perda auditiva neurossensorial súbita. Contudo, atualmente não há consenso em como para administrá-los, se em dose única ou múltiplas doses diárias. Objetivo: Nosso objetivo é avaliar o resultado do tratamento da perda auditiva neurossensorial súbita com uma dose única ou várias doses diárias de tratamento com esteróides. Método: Um total de 94 pacientes que foram diagnosticados e tratados para perda auditiva neurossensorial súbita e acompanhados por mais de três meses pós-tratamento foram avalia-dos retrospectivamente. Os pacientes foram divididos em grupos de dose única diária e dose diária dividida em múltiplas tomadas, baseado em seu regime medicamentoso. Os limiares auditivos foram medidos repetidamente: na visita inicial e em 1 semana, 1 mês e 3 meses após o tratamento inicial. Os resultados do tratamento foram analisados comparando-se as taxas de recuperação da audição e as alterações audiométricas pós-tratamento. Resultados: O limiar auditivo foi significativamente reduzido aos três meses pós-tratamento em ambos os grupos. A taxa de recuperação auditiva no grupo de dose única foi significativamente maior do que no grupo de dose diária dividida em múltiplas tomadas. As alterações audiométricas não mostraram diferença estatística, tanto no limiar de tom puro quanto na discriminação da fala. Conclusão: Quando esteroides orais são indicados para perda auditiva neurossensorial súbita, tanto uma dose única quanto múltiplas doses podem ser eficazes para o tratamento e têm resultados comparáveis. No entanto, o regime de dose única diária parece ser mais eficaz do que o regime de dose diária dividida em múltiplas tomadas.

ABSTRACT

ABSTRACT Pauci-immune glomerulonephritis (GN) is more common in elderly people compared to children and the etiology is not completely understood yet. Antineutrophil cytoplasmic antibody (ANCA) positivity occurs in 80% of the patients. We report a case of a 7-year-old girl who presented with malaise and mildly elevated creatinine diagnosed as ANCA-associated pauci-immune crescentic glomerulonephritis with crescents in 20 of 25 glomeruli (80%). Of these 20 crescents, 12 were cellular, 4 fibrocellular, and 4 globally sclerotic. She did not have purpura, arthritis, or systemic symptoms and she responded well to initial immunosuppressive treatment despite relatively severe histopathology. The patient was given three pulses of intravenous methylprednisolone (30 mg/kg on alternate days) initially and continued with cyclophosphamide (CYC; 2 mg/kg per day) orally for 3 months with prednisone (1 mg/kg per day). In one month, remission was achieved with normal serum creatinine and prednisone was gradually tapered. The case of this child with a relatively rare pediatric disease emphasizes the importance of early and aggressive immunosuppressive treatment in patients with renal-limited ANCA-associated pauci-immune crescentic GN even if with a mild clinical presentation. As in our patient, clinical and laboratory findings might not always exactly reflect the severity of renal histopathology and thus kidney biopsy is mandatory in such children to guide the clinical management and predict prognosis.


RESUMO A glomerulonefrite (GN) pauci-imune é mais comum em idosos em comparação com crianças, e a etiologia ainda não é completamente compreendida. A positividade do anticorpo citoplasmático antineutrófilo (ANCA) ocorre em 80% dos pacientes. Relatamos o caso de uma menina de 7 anos de idade que apresentou mal-estar e creatinina discretamente elevada, diagnosticada como glomerulonefrite rapidamente progressiva pauci-imune associada a ANCA com crescentes em 20 dos 25 glomérulos (80%). Destes 20 crescentes, 12 eram celulares, 4 fibrocelulares e 4 globalmente escleróticos. Ela não apresentava púrpura, artrite ou sintomas sistêmicos e respondeu bem ao tratamento imunossupressor inicial, apesar da histopatologia relativamente grave. A paciente recebeu três pulsos de metilprednisolona intravenosa (30 mg/kg em dias alternados) inicialmente e continuou com ciclofosfamida (2 mg/kg por dia) por via oral durante 3 meses com prednisona (1 mg/kg por dia). Em um mês, a remissão foi alcançada com creatinina sérica normal e a prednisona foi gradualmente reduzida. O caso desta criança com uma doença pediátrica relativamente rara enfatiza a importância do tratamento imunossupressor precoce e agressivo em pacientes com GN rapidamente progressiva renal associada à ANCA, mesmo com uma apresentação clínica leve. Como em nossa paciente, os achados clínicos e laboratoriais podem nem sempre refletir exatamente a gravidade da histopatologia renal e, assim, a biópsia renal é obrigatória nessas crianças para orientar a conduta clínica e auxiliar no prognóstico.

ABSTRACT

Resumo Esclerite Posterior (EP) é uma inflamação do segmento escleral posterior, de etiologia inflamatória ou infecciosa, pouco diagnosticada, com evolução rápida, progressiva e irreversível com severo comprometimento visual, principalmente se o diagnóstico e o tratamento da (EP) não forem realizados a tempo hábil. A dor ocular, dor à movimentação ocular, cefaléia e embaçamento visual são os principais sinais e sintomas. Pode ser de causa Idiopática ou associada a doença sistêmica em até 45% dos caso. A Artrite Reumatoide é descrita como a associação mais comum. Causas infecciosas podem estar presente tais como: Herpes Simples, Herpes Zoster Oftálmico, Sífilis e Tuberculose. A bilateralidade pode ocorrer em até 35% dos casos sendo mais prevalente em mulheres a partir da quinta década de vida.


Abstract Posterior Scleritis (PS) is an inflammation of the posterior scleral segment, of low inflammatory or infectious etiology, with a rapid, progressive and irreversible evolution with severe visual impairment, especially if the diagnosis and treatment of (PS) are not performed in time skillful. Ocular pain, eye movement pain, headache and visual haze are the main signs and symptoms. It can be of idiopathic cause or associated with systemic disease in up to 45% of the cases. Rheumatoid arthritis is described as the most common association. Infectious causes may be present such as: Simple Herpes, Ophthalmic Herpes Zoster, Syphilis and Tuberculosis. Bilaterality can occur in up to 35% of cases being more prevalent in women from the fifth decade of life.

ABSTRACT

Abstract Background: Recommendations of the Myopathy Committee of the Brazilian Society of Rheumatology for the management and therapy of systemic autoimmune myopathies (SAM). Main body: The review of the literature was done in the search for the Medline (PubMed), Embase and Cochrane databases including studies published until June 2018. The Prisma was used for the systematic review and the articles were evaluated according to the levels of Oxford evidence. Ten recommendations were developed addressing the management and therapy of systemic autoimmune myopathies. Conclusions: Robust data to guide the therapeutic process are scarce. Although not proven effective in controlled clinical trials, glucocorticoid represents first-line drugs in the treatment of SAM. Intravenous immunoglobulin is considered in induction for refractory cases of SAM or when immunosuppressive drugs are contra-indicated. Consideration should be given to the early introduction of immunosuppressive drugs. There is no specific period determined for the suspension of glucocorticoid and immunosuppressive drugs when individually evaluating patients with SAM. A key component for treatment in an early rehabilitation program is the inclusion of strengthbuilding and aerobic exercises, in addition to a rigorous evaluation of these activities for remission of disease and the education of the patient and his/her caregivers.

ABSTRACT

Introducción: Las resecciones hepáticas mayores pueden presentar una alta morbimortalidad en relación al sangrado intraoperatorio. La utilización de la maniobra de Pringle permite disminuir esta complicación a costa de un daño por isquemia-reperfusión. Una estrategia para minimizarla es el uso de corticoides perioperatorios. Objetivo: Evaluar el uso de metilprednisolona en dosis bajas (< 500 mg) en pacientes sometidos a resección hepática mayor con maniobra de Pringle en la incidencia de daño por isquemiareperfusión, morbilidad y mortalidad perioperatoria. Material y Métodos: Estudio retrospectivo utilizando la base de datos de hepatectomías entre los años 2000 y 2015. De un total de 171 resecciones hepáticas mayores, 62 utilizaron clampeo vascular. Se establecieron dos grupos: (A) aquellos que recibieron metilprednisolona inmediatamente previo al clampeo (n = 27) y (B) pacientes sin metilprednisolona (n = 35). Se evaluó el daño por isquemia-reperfusión por alteración de las pruebas hepáticas en los días 1, 3 y 5. Resultados: Los pacientes del grupo A tuvieron mayor tiempo de isquemia (43 + 3,3 vs 27 + 2,1 min, p < 0,05) que el grupo B, con una significativamente menor elevación de las fosfatasas alcalinas y bilirrubina en los días 1 y 5 poshepatectomía. No se observó diferencias en la magnitud del sangrado y no hubo diferencias en morbimortalidad. Conclusiones: La utilización de dosis bajas de metilprednisolona parece disminuir el impacto del DIR relacionado a la resección hepática bajo clampeo vascular, evitando los efectos adversos de la administración de esteroides en dosis altas.


Introduction: Liver resections may be associated with high morbidity and mortality due to intraoperative bleeding. Pringle maneuver reduces this complication at the expense of ischemia-reperfusion injury. Current strategies to minimize reperfusion injury include the use of perioperative corticosteroids. Objective: To assess the use of methylprednisolone in low doses (< 500 mg) in patients submitted to major hepatic resection under Pringle maneuver in the incidence of ischemia-reperfusion injury, peri-operative morbidity, and mortality. Material and Methods: Retrospective study from the liver resections database undertaken between the years 2000-2015 in our center. One hundred and seventy-one major liver resections were done, in 62 under Pringle maneuver. Two groups were established: (A) Patients administered methylprednisolone immediately before Pringle maneuver (n = 27) and (B) those without steroid (n = 35). We assessed ischemia-reperfusion injury by measuring liver tests on days 1, 3 and 5. Results: Patients in group A had longer ischemia time (43 ± 3.3 vs. 27 ± 2.1 min, p < 0.05) than those of group B, and significantly lower elevation of serum phosphatase alkaline and bilirubin on days 1 and five post-hepatectomy. We did not observe any difference in bleeding magnitude, and there were no differences in morbidity or mortality. Conclusions: The use of low doses of methylprednisolone seems to diminish the impact of ischemia-reperfusion injury related to major hepatic resection under Pringle maneuver avoiding the adverse side effects of high dose steroid.

ABSTRACT

Abstract We present a case study of Tolosa-Hunt syndrome, a rare idiopathic disease, that is characterized by painful ophthalmoplegia of strong intensity, generally affecting the third cranial nerve, and, less frequently, the fourth or the sixth cranial nerves. Usually, there is no visual impairment. The treatment is based on corticosteroids with satisfactory results in most cases although recurrences can occur at intervals from months to years. In our case, the patient presented sudden pain periorbital associated with cranial nerves involvement, which have an excellent outcome after treatment with corticosteroids, with no relapses until today.


Resumo Nós apresentamos um caso de Síndrome de Tolosa-Hunt, uma doença idiopática rara, caracterizada por oftalmoplegia dolorosa, de forte intensidade, geralmente afetando o terceiro par craniano, e, menos frequentemente, o quarto e/ou o sexto par. Geralmente, não há acometimento visual. O tratamento é feito com base em corticóides com resultados satisfatórios na maior parte dos casos, embora recorrências possam ocorrer após meses a anos.

ABSTRACT

RESUMO Apresentamos um caso de um paciente de 46 anos, sexo masculino com diagnóstico de neurite ótica em olho direito associado a infecção aguda por Chikungunya. Os sintomas iniciais eram dor e baixa acuidade visual em olho direito associado a febre e poliartralgia simétrica há uma semana. Ao exame a acuidade visual era de 20/60 em olho direito e 20/20 em olho esquerdo, fundoscopia evidenciou edema de papila à direita. Foi iniciado imediatamente pulsoterapia com metilprednisolona por 7 dias e foi observada melhora do quadro de neurite no seguimento de 1, 3 e 12 meses, porém melhora parcial da acuidade visual, Dentre as causas investigadas identificou-se sorologia anti Chikungunya IgM positivo.


ABSTRACT We present a case of optic neuritis secondary to Chikungunya virus infection. Male, 46 yo, initial symptoms were pain and low visual acuity in the right eye associated to fever and symmetrical polyarthralgia one week ago. At the examination the visual acuity was 20/60 in the right eye and 20/20 in the left eye, fundoscopy showed papillo edema on the right eye. Immediately initiated pulse therapy with methylprednisolone for 7 days and improvement of the neuritis was observed in the follow-up of 1, 3 and 12 months, but partial improvement of the visual acuity. Among the investigated causes, Chikungunya IgM positive serology was identified.

ABSTRACT

Abstract Introduction Idiopathic sudden sensorineural hearing loss (ISSNHL) is hearing loss of at least 30 dB in at least 3 contiguous frequencies within at least 72 hours. There are many different theories to explain it, and many differentmodalities are used for its management, such as: systemic steroids (SSs), intratympanic steroid injection (ITSI), hyperbaric oxygen therapy (HOT), antiviral drugs, and vasodilators or vasoactive substances. Objectives This study aims to evaluate the efficacy of the combination of the most common treatmentmodalities of ISSNHL and to compare the results if HOTwas not one of the treatment modalities administered. Methods The study was conducted with 22 ISSNHL patients with ages ranging from 34 to 58 years. The patients were divided into 2 groups; group A included 11 patients managed by SSs, ITSI, antiviral therapy, and HOT simultaneously, and group B included 11 patients exposed to the aforementioned modalities, with the exception of HOT. Results After one month, all of the patients in group A showed total improvement in hearing in all frequencies, with pure tone average (PTA) of 18.1 ± 2.2, while in group B, 5/11 (45.5%) patients showed total improvement, and 6 /11 (54.5%) patients showed partial improvement, with a total mean PTA of 28.1 ± 8.7. Conclusion The early administration of HOT in combination with other clinically approved modalities (SSs, ITSI, antiviral therapy) provides better results than the administration of the same modalities, with the exception of HOT, in the treatment of ISSNHL.

ABSTRACT

La vasculitis Primaria del Sistema Nervioso Central (VPSNC) se refiere a un grupo de enfermedades que resultan de la inflamación y destrucción de los vasos sanguíneos de la medula espinal, encéfalo y meninges, tanto en el sector venoso como arterial. La presentación es heterogénea y poco sistematizable. El diagnóstico se establece con un cuadro clínico compatible, una angiografía que evidencie vasculitis y/o biopsia del parénquima encefálico o meninges. Las alteraciones en los estudios de imagen son constantes pero inespecíficas para el diagnóstico y se acompañan habitualmente de alteraciones en el líquido cefalorraquídeo (LCR) y electroencefalograma (EEG) Presentamos un paciente con probable VPSNC basados en un cuadro clínico compatible, hallazgos imagenológicos sugestivos, junto con alteraciones en LCR y EEG. Se realizó tratamiento en base a corticoides e inmunosupresores con mala respuesta y evolución.


The primary central nervous system vasculitis (VPSNC) refers to a group of diseases that result from inflammation and destruction of the blood vessels of the spinal cord, brain and meninges, both in the venous and arterial sector. The presentation is heterogeneous and unsystematized. The diagnosis is made based on compatible symptoms, supported by an angiography showing evidence of vasculitis and/or biopsy of the brain parenchyma or meninges. Alterations in imaging studies are consistent but nonspecific for diagnostic and are usually accompanied by alterations in the electroencephalogram (EEG) and cerebrospinal fluid (CSF). We present a clinical case of probable VPSNC based on clinical presentation and findings on imagenological studies suggestive vasculitis, along with alterations in CSF and EEG. Treatment was based on Corticosteroids and immunosuppressive agents with poor response and evolution.

ABSTRACT

La necrólisis epidérmica tóxica y el síndrome de StevensJohnson son enfermedades mucocutáneas raras que están asociadas a una evolución prolongada y a un desenlace potencialmente mortal. Principalmente están inducidas por fármacos y las tasas de mortalidad son muy elevadas. Aunque la piel es la más comprometida, también pueden estar afectados múltiples aparatos o sistemas como el cardiovascular, pulmonar, gastrointestinal y urinario. En este artículo, describimos el caso de un paciente con síndrome de Stevens-Johnson asociado al tratamiento con metotrexato, quien desarrolló insuficiencia cardíaca aguda y hemorragia gastrointestinal además de las manifestaciones en la piel. El paciente recibió un tratamiento satisfactorio con metilprednisolona e inmunoglobulina por vía intravenosa y continuó la quimioterapia con metotrexato.


Toxic epidermal necrolysis and Stevens-Johnson syndrome are rare mucocutaneous diseases which are associated with a prolonged course and potentially lethal outcome. They are mostly drug induced and mortality rates are very high. Although mostly skin is involved, multiple organ systems such as cardiovascular, pulmonary, gastrointestinal, and urinary systems may be affected. Here, we report a case of StevensJohnson Syndrome associated with methotrexate treatment who developed acute cardiac failure and gastrointestinal hemorrhage beside skin findings. He had been treated with intravenous immunglobulin and methylprednisolone succesfully and continued chemotherapy with methotrexate treatment again.

ABSTRACT

Resumo Esclerite posterior é uma doença inflamatória ocular que acomete a esclera e cujo diagnóstico é difícil. A clínica da doença envolve a piora da qualidade visual com dor ocular e achados do segmento posterior, como descolamento de retina seroso, dobras de coroide, edema de disco óptico e espessamento escleral. Deve-se ficar atento aos achados sistêmicos, pois, muitas vezes, está associada a doenças como artrite reumatoide, lúpus eritematoso sistêmico, doença inflamatória intestinal e doenças infecciosas, como sífilis e tuberculose. Este trabalho objetiva descrever dois casos: uma paciente com quadro de esclerite posterior bilateral simultânea, sem alterações sistêmicas correlacionadas com a doença. A apresentação bilateral é incomum nesta patologia; e outro caso de esclerite anterior e posterior unilateral recorrente.


Abstract Posterior scleritis is an ocular inflammatory disease that affects the sclera e whose diagnosis is difficult. The main clinical manifestations are worsening of visual quality, ocular pain and finding in the posterior segment, such as serous retinal detachment, choroidal folds, optic disc edema and sclera thickening. We should award for systemic findings, because it is often accompanied by rheumatoid arthritis, systemic lupus erythematosus, inflammatory bowel disease and infections, such as syphilis and tuberculosis.This paper aims to describe two cases: one patient with simultaneous bilateral posterior scleritis without systemic alterations correlated with the disease. Bilateral presentation is uncommon in this pathology; and another case of recurrent unilateral anterior and posterior scleritis.

ABSTRACT

OBJECTIVES: To describe a case series of spontaneous pneumomediastinum in dermatomyositis and to review the literature. METHODS: This was a retrospective single-center case series, reporting 9 patients with pneumomediastinum and defined dermatomyositis, followed from 2005 to 2017. RESULTS: Median age of patients: 33 years; cutaneous and pulmonary involvement in all cases; constitutional symptoms in 88.8% of patients; involvement of the joints in 11.1%, gastrointestinal tract in 44.4%, and muscles in 77.7%; subcutaneous emphysema was observed in 55.5% and pneumothorax in 11.1%, respectively. Muscle weakness was observed in 77.7% of cases and with a median level of serum creatine phosphokinase of 124U/L. Drawing on results for our literature review, the overall analysis showed that the risk factors associated with spontaneous pneumomediastinum were: (a) a history of interstitial pneumopathy; (b) normal or low levels of muscle enzymes; (c) previous use of systemic glucocorticoid; (d) over 50% of patients had subcutaneous emphysema; (e) high mortality as a consequence of severity of the interstitial lung disease. CONCLUSIONS: Our case series revealed that pneumomediastinum is a rare complication in dermatomyositis that occurs in patients with a history of interstitial pneumopathy and may be accompanied by subcutaneous emphysema and pneumothorax.


OBJETIVOS: Descrever série de casos de pneumomediastino espontâneo em portadores de dermatomiosite e revisar a literatura. MÉTODOS: Trata-se de série de casos, único centro, relatando 9 pacientes com pneumomediastino e dermatomiosite definida, acompanhados de 2005 a 2017. RESULTADOS: A mediana da idade dos pacientes foi de 33 anos. Sintomas constitucionais estavam presentes em 88,8% dos pacientes. Houve acometimento cutâneo e pulmonar em todos os casos, acometimento das articulações em 11,1%, trato gastrointestinal em 44,4% e musculatura em 77,7% dos pacientes. Enfisema subcutâneo foi observado em 55,5% e pneumotórax em 11,1%, respectivamente. A fraqueza muscular foi observada em 77,7% dos casos, com um nível médio de creatinofosfoquinase sérica de 124U/L. Com base nos resultados da revisão da literatura, a análise geral mostrou que: os fatores de risco associados ao pneumomediastino espontâneo foram: história de pneumopatia intersticial, níveis normais ou baixos de enzimas musculares, uso prévio de glicocorticoide sistêmico; >50% dos pacientes tiveram enfisema subcutâneo; houve alta mortalidade como consequência da gravidade da doença pulmonar intersticial. CONCLUSÕES: Nossa série de casos revelou que o pneumomediastino é uma complicação rara na dermatomiosite e que ocorre em pacientes com história de pneumopatia intersticial e pode ser acompanhada por enfisema subcutâneo e pneumotórax.

ABSTRACT

Glucocorticoid insensitivity is an important barrier to the treatment of several inflammatory diseases, including acute lung injury (ALI). Saquinavir (SQV) is an inhibitor of the human immunodeficiency virus protease, and the therapeutic effects of SQV in ALI accompanied with glucocorticoid insensitivity have not been previously investigated. In this study, the effects of SQV on lipopolysaccharide (LPS)-mediated injury in human pulmonary microvascular endothelial cells (HPMECs), human type I alveolar epithelial cells (AT I), and alveolar macrophages were determined. In addition, the effects of SQV on an LPS-induced ALI model with or without methylprednisolone (MPS) were studied. In LPS-stimulated HPMECs, SQV treatment resulted in a decrease of high mobility group box 1 (HMGB1), phospho-NF-κB (p-NF-κB), and toll-like receptor 4 (TLR4), and an increase of VE-cadherin. Compared to MPS alone, MPS plus SQV attenuated the decrease of glucocorticoid receptor alpha (GRα) and IκBα in LPS-stimulated HPMECs. HMGB1, TLR4, and p-NF-κB expression were also lessened in LPS-stimulated alveolar macrophages with SQV treatment. In addition, SQV reduced the injury in human AT I with a decrease of HMGB1 and p-NF-κB, and with an increase of aquaporin 5 (AQP 5). SQV ameliorated the lung injury caused by LPS in rats with reductions in vascular permeability, myeloperoxidase activity (MPO) and histopathological scores, and with lowered HMGB1, TLR4, and p-NF-κB expression, but with enhanced VE-cadherin expression. By comparison, SQV plus MPS increased GRα and IκBα in lung tissues of rats with ALI. This study demonstrated that SQV prevented experimental ALI and improved glucocorticoid insensitivity by modulating the HMGB1/TLR4 pathway.

ABSTRACT

La enfermedad injerto contra huésped es una entidad en la cual las células inmunológicas competentes de un tejido injertado reconocen y dañan antígenos presentes en el receptor del trasplante, que es incapaz de defenderse de ellas. Es una complicación frecuente del trasplante alogénico de médula ósea, y con menor frecuencia se produce luego de trasplantes de órganos sólidos o transfusiones de hemoderivados no irradiados. Se comunica el caso de una paciente de sexo femenino de 23 años, con leucemia linfoblástica aguda.y trasplante alogénico de médula ósea, que presentó una enfermedad injerto contra huésped con compromiso cutáneo y gastrointestinal dependiente de corticoides, con mejoría de los signos y síntomas cutáneos luego del tratamiento con infliximab y fotoféresis extracorpórea. (AU)


Graft versus host disease is an entity in which competent grafted immune cells recognize and damage tissue antigens present in the transplant recipient, who is unable to defend from them. It is one of the most serious complications in patients undergoing allogeneic bone marrow transplantation, although less frequently it may be associated with solid organ transplants or transfusions of not irradiated blood products. We report the case of a 23 year-old patient with acute lymphoblastic leukemia and allogeneic bone marrow transplantation, that presented graft versus host disease with skin and gastrointestinal involvement, dependent on corticosteroids, that showed improvement in signs and skin symptoms after treatment with infliximab and extracorporeal photopheresis.

ABSTRACT

PURPOSE: To systematically evaluate whether oral steroids can be used with the same efficacy and safety in comparison with the intravenous regimen for treatment of multiple sclerosis relapses. METHOD: We searched Medline, Embase and Cochrane Library and systematically reviewed articles comparing outcomes of oral versus intravenous steroids for acute relapses in patients with a clinically definite diagnosis of multiple sclerosis. RESULTS: Six articles with 414 participants in total were analyzed. Five of the included trials reported the proportion of patients experiencing improvement in Expanded Disability Status Scale after receiving either oral or intravenous methylprednisolone treatment at four weeks; the pooled results showed that there was no statistically significant difference (OR 0.96; 95% CI 0.60, 1.54; p=0.86) between treatments. Three trials reported the detailed results of adverse events, indicating the two treatments appear to be equally safe. Two trials revealed that there was no significant difference in gadolinium enhancement activity on magnetic resonance imaging. One trial showed that the mean area under the concentration-time curve (AUC) at 24 and 48 hours did not differ between groups. CONCLUSION: No significant differences were found in terms of clinical (benefits and adverse events), radiological and pharmacological outcomes in multiple sclerosis relapses in patients after oral or intravenous steroids treatment. Our meta-analysis provides evidence that oral steroid therapy is not inferior to intravenous steroid therapy. Thus oral administration may be a favorable substitute for intravenous medication of multiple sclerosis relapses.


PROPÓSITO: Avaliar de forma sistemática se esteroides orais podem ser utilizados com a mesma eficácia e segurança em comparação com o regime intravenoso para o tratamento de recaídas da esclerose múltipla (MS). MÉTODO: Foram pesquisados Medline, Embase e Cochrane Library e sistematicamente revistos artigos comparando resultados de esteroides orais versus intravenosos para recaídas agudas em pacientes com diagnóstico de esclerose múltipla clinicamente definida. RESULTADOS: Seis artigos com 414 participantes no total foram analisados. Cinco dos estudos incluídos relataram a proporção de doentes com melhoria através de "Expanded Disability Status Scale" depois de receber um ou outro tratamento: metilprednisolona oral ou intravenosa por quatro semanas. Os resultados combinados mostraram que não houve diferença estatisticamente significativa (OR 0,96; 95% 101 0,60, 1,54 ; p = 0,86). Três estudos mostraram os resultados detalhados de eventos adversos, indicando que os dois tratamentos parecem ser igualmente seguros. Dois ensaios revelaram que não havia nenhuma diferença significativa no aumento de atividade de gadolínio via imagens por ressonância magnética. Um estudo mostrou que a área média sob as curvas de concentração-tempo (AUC) às 24 horas e 48 horas não diferiram entre os grupos. CONCLUSÃO: Não foram encontradas diferenças significativas em termos de clínicos (benefícios e eventos adversos) ou nos resultados radiológicos e farmacológicos em pacientes pós-esteroides por via oral ou intravenosa no tratamento de várias recaídas de esclerose. Nossa metanálise fornece evidências de que a terapia com esteroides por via oral não é inferior à terapia com esteroides por via intravenosa. Assim, a administração oral pode ser um substituto favorável para medicação intravenosa de recidivas da esclerose múltipla.
