ABSTRACT

PURPOSE: To assess the prevalence of autoimmune diseases (ADs) associated with ocular cicatricial pemphigoid (OCP) and analyze clinical, laboratory, and treatment associations between these entities. METHODS: A multicentre cross-sectional study of patients with an OCP diagnosis. The population was divided into two groups according to their association with other ADs or not. Clinical, laboratory and treatment variables were described and compared between groups. A multivariable logistic regression analysis was performed to identify variables that could suggest the association between OCP and ADs. RESULTS: Eighty-eight patients were recruited, with a mean age at diagnosis of 64.3 years (SD 11.9). Biopsy was performed in 86.8% of the patients. There was a median delay of 2 years from the onset of symptoms to diagnosis. Extraocular involvement was evidenced in 11.5%. The group associated with ADs included 24 patients (27.3%). The most prevalent diagnosis was Sjögren´s syndrome. Hypergammaglobulinemia was associated with ADs and OCP, adjusted for age, sex, smoking, skin and mucosal involvement, and erythrocyte sedimentation rate (OR 8.7; 95%CI 1.6-46.8; p = 0.012). CONCLUSIONS: Due to OCP's autoimmune nature, it could coexist with other ADs. This study observed that more than a quarter of the population presented with this association, and hypergammaglobulinemia could suggest it.

ABSTRACT

OBJECTIVE: To estimate incidence and prevalence of polymyalgia rheumatica (PMR) and giant cell arteritis (GCA) in a university hospital-based health management organization (Hospital Italiano Medical Care Program) in Argentina. METHODS: Overall and sex-specific incidence rates (IRs) and prevalence were calculated (age ≥ 50 yrs). Incidence study followed members with continuous affiliation ≥ 1 year from January 2000 to December 2015. Diagnosis as per the 2012 European Alliance of Associations for Rheumatology/American College of Rheumatology (ACR) criteria for PMR or the ACR 1990 criteria for GCA. Prevalence was calculated on January 1, 2015. RESULTS: There were 176,558 persons who contributed a total of 1,046,620 person-years (PY). Of these, 825 developed PMR, with an IR (per 100,000 PY) of 78.8 (95% CI 73.4-84.2) overall, 90.1 (95% CI 82.9-97.2) for women, and 58.9 (95% CI 51.1-66.6) for men. Ninety persons developed GCA; the IR was 8.6 (95% CI 6.8-10.4) overall, 11.1 (95% CI 8.5-10.6) for women, and 4.2 (2.2-6.3) for men. There were 205 prevalent PMR cases and 23 prevalent GCA cases identified from a population of 80,335. Prevalence of PMR was 255 per 100,000 (95% CI 220-290) overall, 280 (95% CI 234-325) for women, and 209 (95% CI 150-262) for men; and the prevalence of GCA was 28.6 per 100,000 (95% CI 16.9-40.3) overall, 36.4 (95% CI 20.1-52.8) for women, and 14.2 (95% CI 0.3-28.1) for men. CONCLUSION: This is the first study of incidence and prevalence of PMR and GCA in Argentina. There were similarities and differences with cohorts from other parts of the world, but population-based epidemiologic studies in Latin America are needed.

ABSTRACT

ANTECEDENTES: El COVID-19 presenta una progresión a cuadros respiratorios graves que pueden culminar con la muerte. Al ser una pandemia, hay necesidad de herramientas de bajo costo que permitan determinar su evolución. El índice neutrófilo-linfocito (INL) es un marcador inflamatorio estudiado en diversas patologías. OBJETIVO: Estimar la asociación entre INL > 3 y mortalidad en pacientes hospitalizados con COVID 19. PACIENTES Y MÉTODOS: Se incluyeron pacientes con diagnóstico de COVID 19 que ingresaron a la sala de internación general de nuestro hospital, desde marzo hasta agosto de 2020. Los pacientes se dividieron en dos grupos: con INL 3. Se realizó un modelo de regresión logística múltiple para estimar la asociación entre el INL > 3 y mortalidad. RESULTADOS: Se incluyeron 711 pacientes con COVID-19. El modelo de regresión logística múltiple mostró asociación entre INL > 3 y mortalidad (OR 3.8; IC95% 1,05 a 13,7; p 0,04) ajustado por edad, días de internación, traslados a terapia intensiva, neumonía grave, valores de proteína-C-reactiva, hipertensión arterial, y comorbilidad neurológica, renal crónica, cardiaca y oncológica previas. COCLUSIÓN: El INL es accesible en la evaluación inicial de los pacientes que se internan con COVID-19, habiéndose asociado en nuestra serie con mortalidad.


BACKGROUND: COVID-19 rapidly progresses to acute respiratory failure and mortality. A pandemic needs an urgent requirement for low-cost and easy-access tools that assess the infection evolution. The neutrophil-lymphocyte ratio (NLR) is an inflammatory biomarker used in several diseases. AIM: To estimate the association between NLR > 3 with mortality in hospitalized patients with COVID 19. METHODS: NLR was analyzed in patients with COVID-19 seen at Hospital Fernandez between March and August 2020. Patients were grouped in those with NLR 3. Clinical characteristics and mortality were analyzed and compared between groups. A multivariable regression model was used to estimate the association between NLR > 3 and mortality. RESULTS: We included 711 patients with COVID-19. In a multivariable regression model, NLR > 3 associated with mortality (OR 3.8; 95% CI 1.05 to 13.7; p 0.04) adjusting by age, days of hospitalization, intensive care requirement, severe pneumonia, C-reactive protein levels, arterial hypertension, and comorbidities. CONCLUSION: NLR was associated with mortality, and it is an accessible and easy tool to use in the first evaluation of hospitalized patients with COVID-19.

ABSTRACT

OBJECTIVE: Complement plays a major role in SLE. Complement participation has been linked to disease activity and damage. Our objective was to estimate the association of complement behaviour with clinical manifestations, visceral injury and mortality in patients with SLE. METHODS: Complement determinations (C3 and C4 levels) were analysed in patients with SLE (fulfilling American College of Rheumatology (ACR) or Systemic Lupus International Collaborating Clinics (SLICC)criteria) seen at a university hospital between 2000 and 2013. Patients were grouped in those with permanent C3 and/or C4 low values (low complement group), those with C3 and C4 constant normal values (normal complement group) and those with fluctuant values (periods of normal and periods of low values: fluctuant group). Clinical characteristics and mortality were analysed and compared between groups. RESULTS: 270 patients with SLE were included (242 females, 89.6%), mean age at diagnosis was 34.2 years (SD 15.8). 75 patients had fluctuant levels of complement, 79 patients had persistent low complement levels and 116 had normal complement levels. Lupus glomerulonephritis was more frequent in patients with fluctuant levels (75%, 56% and 49%, respectively, p=0002). The normal complement group had less frequency of haematological involvement and anti-double stranded DNA (dsDNA) antibodies. At the end of the follow-up, 53% of the patients had damage (SLICC/ACR ≥1). In a Cox proportional hazard model age at diagnosis, neurological impairment, thrombocytopaenia and corticosteroids were associated with more damage, while hydroxychloroquine was a protective factor. There were no differences between complements groups on accumulated damage. Ten-year survival rate was 93%, 93.5% and 92% for the normal complement group, the persistently low group and the fluctuant group, respectively. CONCLUSIONS: Patients with constant normal complement had lower prevalence of haematological involvement and anti-dsDNA, while patients with fluctuant complement had higher renal impairment. Neither the persistent low complement nor the fluctuant complement groups had increased mortality and/or visceral damage.

ABSTRACT

La osificación heterotópica es una condición patológica que conduce al desarrollo de hueso en el tejido blando. En la piel se denomina osteoma cutis. Estas lesiones se clasifican en primarias o secundarias. Las causas secundarias constituyen el 85% y son consecuencia de enfermedades inflamatorias, infecciones, tumores, traumatismos, lesiones de médula espinal y cirugías. Si bien la osificación heterotópica es benigna e infrecuente, puede ser una enfermedad debilitante que, asociada a dolor y rigidez, provoque mayor comorbilidad en relación con la enfermedad que la desencadenó. Comunicamos el caso de un paciente que padeció osteoma cutis asociado a tuberculosis osteoarticular


Heterotopic ossification is a patologic condition that leads bone formation in soft tissue. In particular, osteoma curtis, which can be primary or secundary, occurs when ossification if found in the skin. Secondary lessions account 85% of the cases described and they are by inflammatory diseases, infections, tumors, traumas, spinal cord lesions and surgeries. Whereas heterotopic ossification is benign and rare, it may result in wasting sickness that in combination with pain and stiffness, adding comorbidity to the disease that triggers. We report here a patient suffering osteomas cutis and osteoarticular tuberculosis. (AU)

ABSTRACT

Antecedentes: Algunos pacientes con granulomatosis eosinofílica con poliangitis (EGPA) y factores de mal pronóstico son refractarios o presentan efectos adversos al tratamiento de inducción (glucocorticoides [GC] y ciclofosfamida [CF]), o recaen durante el mantenimiento (GC y azatioprina), haciendo necesaria la búsqueda de alternativas terapéuticas. En ensayos clínicos, el rituximab (RTX) demostró ser eficaz para el tratamiento de las vasculitis asociadas al ANCA; sin embargo, los pacientes con EGPA no fueron incluidos. Objetivo: Revisar y analizar la bibliografía sobre la uso de RTX para el tratamiento de la EGPA. Métodos: La búsqueda se realizó en MEDLINE y LILACS (1965 y 1986, respectivamente, hasta febrero del 2014). Resultados: Se incluyó a 27 pacientes. La indicación de RTX fue por enfermedad refractaria (n = 20), recaída (n = 5) y nuevo diagnóstico (n = 2). Los órganos afectados fueron los pulmones, el sistema nervioso periférico, el riñón y los ojos. Se observó remisión en 16 y respuesta en 8 pacientes. Conclusiones: El RTX fue eficaz y bien tolerado para el tratamiento de la EGPA (AU)


Background: The general consensus is that for patients with EGPA with poor prognosis, intensive therapy with both GC and CF is indicated. The maintenance of remission is made with GC and AZA. A considerable number of patients with EGPA are refractory to first line therapy, experience dose-limiting side effects or relapse. In clinical trials, RTX was effective for the treatment of ANCA-associated vasculitis. However, patients with a diagnosis of EGPA were not included. Objective: to review and analyze the published literature regarding the use of RTX in the treatment of EGPA. Methods: The literature search was performed in MEDLINE and LILACS from 1965 and 1986 respectively until february 2014. Results: 27 patients were included. RTX treatment was due to refractory disease (n = 20), relapse (n = 5) and with newly diagnosed (n = 2). The affected organs were the lungs, peripheral nervous system, kidney and the eyes. Sixteen patients had clinical remission and 8 patients had clinical response. Conclusions: RTX was effective and well tolerated for the treatment of EGPA (AU)

ABSTRACT

El síndrome de activación macrofágica (SAM) es una entidad poco frecuente y grave, caracterizadapor una excesiva activación y proliferación de macrófagos y linfocitos T. Los factoresdesencadenantes son las infecciones, drogas, enfermedades malignas y autoinmunes. Ellupus eritematoso sistémico frecuentemente se asocia al SAM. En la práctica clínica, eldiagnóstico diferencial entre lupus eritematoso sistémico activo, SAM e infección es ungran desafío para el médico internista. Esto se debe a que los signos, síntomas y datos delaboratorio de estas entidades se superponen. El propósito de nuestro trabajo es el reportarlos casos de 2 pacientes con lupus eritematoso sistémico activo, SAM y sepsis...


Macrophage activation syndrome (MAS) is a rare and severe entity characterized by excessive activation and proliferation of macrophages and T-lymphocytes. The usual triggers are infections, drugs, malignancy and autoimmune diseases. Systemic lupus erythematosus is frequently associated with MAS. In clinical practice, differential diagnosis between active systemic lupus erythematosus, MAS and an infection is a great challenge for the internist. This happens because signs, symptoms and laboratory data from these illnesses overlap to a large degree. The purpose of this paper is to present a report on two patients with active systemic lupus erythematosus, MAS, and sepsis...

ABSTRACT

Antecedentes: Existen pocos estudios descriptivos sobre las causas de internación de los pacientes con vasculitis asociadas a ANCA (VAA), todos son retrospectivos y realizados en unidades de cuidados intensivos. Objetivo: Investigar la epidemiología, los hallazgos clínicos y la evolución de los pacientes con VAA durante su internación, e identificar los factores pronósticos asociados a mortalidad. Materiales y métodos: Se incluyeron los pacientes con diagnóstico de VAA internados en el Hospital Juan A. Fernández y la Clínica San Camilo (Ciudad Autónoma de Buenos Aires, Argentina), entre el 1 de enero de 2011 y el 31 de diciembre de 2013. Resultados: Treinta y cuatro pacientes fueron incluidos, 18 (53%) de sexo femenino. Edad media de 60 ± 12 años. En 9 (26%) pacientes el diagnóstico de VAA se realizó en la internación. La Poliangeítis Microscópica (MPA) fue la vasculitis más común (50%). Dieciocho (53%) pacientes se internaron por actividad clínica de la vasculitis. Órganos/sistemas afectados: pulmón (n=9), riñón (n=6), otorrinolaringológicas (n=5), sistema nervioso periférico (n=5) y piel (n=2). Ocho (23,5%) pacientes fueron admitidos por complicaciones infecciosas y ocho por otras causas. Fallecieron 8 (23,5%) pacientes, 3 debido a actividad de la vasculitis, 4 debido a complicaciones infecciosas y 1 por falla multiorgánica (2º infusión pamidronato). Los que ingresaron a UCI tuvieron mayor mortalidad (p=0,001); el sexo (p=0,69), la edad (p=0,15), el diagnóstico “de novo” de vasculitis (p=0,4), el BVAS y VDI no mostraron diferencias entre los sobrevivientes y fallecidos. La mortalidad de los pacientes que ingresaron por actividad de la vasculitis comparado con los que ingresaron por complicaciones infecciosas fue similar (p=0,6). Conclusiones: La causa más frecuente de internación en pacientes con VAA fue la actividad de la enfermedad, seguida por las causas infecciosas.


Background: Few retrospective studies have described the clinical course of patients with ANCA-asocciated vasculitis (AAV) admitted to the hospital, all of them in intensive care units (ICU).Objective: To study the epidemiology, clinical features and outcome of patients with AAV admitted to the hospital, and to identify the prognostic factors associated with mortality.Methods: Patients with AAV admitted to the Juan A. Fernández Hos-pital and San Camilo Clinic (Buenos Aires City, Argentina) betweenJanuary 2011 and December 2013 were included. Results: Thirty four patients [18 (53%) female] with an average 60 ±12 years old were included. AAV was diagnosed in 9 (26%) patientsin the hospital. Microscopic Polyangiitis was the most common AAV. Eighteen (53%) patients were admitted due to active vasculitis. Lung(n=9), kidney (n=6), ear-nose-throat (n=5), peripheral nervous system (n=5) and skin (n=2) were the organs/systems involved. Other reasons for admission were: infection and metabolic conditions [8(23.5%) patients each]. Eight (23.5%) patients died, 3 due to active vasculitis, 4 due to infection and 1 patient due to multiorgan failure after pamidronate treatment. Mortality was significantly higher for patients who were admitted in ICU (p=0.001); gender (p=0.69), age(p=0.15), new diagnosis of AAV (p=0.4), BVAS and VDI showed no significant differences between survival and dead patients. The mortality was similar (p=0.6) between the patients with active vasculitis and the patients with infections. Conclusion: The main reason for hospitalization in AAV patients was active vasculitis followed by infection. Mortality rate was high and the main causes were infections regardless the diagnosis at admission.

ABSTRACT

Las vasculitis ANCA asociadas son la causa más frecuente de síndrome pulmo-renal (SPR); dentro de este grupo se halla la poliangeitis con granulomatosis (GPA). El objetivo de este trabajo fue describir las características clínicas y de laboratorio de pacientes con SPR y GPA, y comparar su sobrevida con un grupo de GPA graves sin SPR. Se revisaron retrospectivamente las historias clínicas de 37 casos de GPA pertenecientes a dos centros terciarios de la Ciudad de Buenos Aires. Se incluyeron para el análisis 13 casos con GPA/SPR; 7 fueron de sexo femenino, la media de edad al diagnóstico fue de 48 años. La media de seguimiento fue 4.66 años. El Birmingham Vasculitis Activity Score (BVAS) inicial fue de 31.13 ± 7.99 vs 18.19 ± 4.45 en el grupo de GPA sin SPR. Doce casos fueron ANCA-c positivos. El tratamiento consistió inicialmente en esteroides y ciclofosfamida; en los casos cuyo compromiso renal fue severo (creatinina plasmática 5mg/dll) se realizó plasmaféresis y diálisis. Se obtuvo la remisión de 8 casos; 2 recayeron durante el seguimiento. Se observaron 6 muertes; 2 fueron debidas a la actividad de la enfermedad, 3 debidas a infecciones y 1 a un accidente cerebrovascular. Todos fallecieron dentro de los 12 meses posteriores al diagnóstico. La mortalidad a los 30 días fue 38.46% en el grupo de GPA/SPR vs. 4.16% en el grupo de GPA sin SPR. El SPR es una de las formas más graves de la GPA y conlleva una elevada morbimortalidad. El diagnóstico debe ser rápido, excluyéndose otras posibles etiologías para poder instaurar un adecuado tratamiento que pueda modificar la mortalidad temprana que se observa en este síndrome. La determinación precoz de los ANCAs en el contexto clínico adecuado sería una herramienta de gran utilidad diagnóstica.

ABSTRACT

El síndrome de Nicolau se produce por la inyección intra-arterial accidental de sustancias de aplicación intramuscular.

Nicolau's syndrome occurs as a result of intra-arterial accidental injection of intramuscular drugs. The clinical presentation includes immediate pain followed by skin local changes and extremities embolism that may lead to necrosis. Intramuscular Benzathine penicillin has been associated with this syndrome, even with adequate injection technique. This drug is of choice for a wide variety of infectious diseases; the most common non-allergic adverse events are vascular. We report here a syphilitic patient who suffered neurovascular adverse effects after intramuscular penicillin G benzathine application.

ABSTRACT

El síndrome de Nicolau se produce por la inyección intra-arterial accidental de sustancias de aplicación intramuscular. Se caracteriza por dolor inmediato en el sitio de la inyección, seguido de alteraciones cutáneas locales y posterior desarrollo de embolias en las extremidades que generan daño isquémico tisular pudiendo llevar a la necrosis. En general se ha adjudicado a la penicilina G benzatínica intrmuscular, aún con técnica de aplicación adecuada, como responsable de este síndrome.
