RESUMO

IgG4-related disease is a heterogeneous group of diseases that can affect a single organ or manifest as a systemic disease. We present the case of a 55-yearold female, admitted for dry cough, fever, progressive dyspnea and respiratory failure. Chest CT showed areas of diffuse ground glass, reticular pattern and alveolar consolidation. She received treatment for community acquired pneumonia and systemic corticosteroids with good response. One month later, she was admitted again due to subglottic stenosis, progression of pulmonary infiltrates, and increased palpebral and submaxillary glands volume. Transbronchial and salivary gland biopsies showed infiltration by IgG4. Increased levels of plasma IgG4 were also detected. Immunosuppressive therapy was given with good response.

RESUMO

Las enfermedades relacionadas con inmunoglobulina G4 (IgG4) son un grupo heterogéneo de cuadros clínicos que pueden afectar un solo órgano o tener compromiso sistémico. Se presenta el caso de una mujer de 55 años, internada por un cuadro de tos seca, fiebre, disnea progresiva e insuficiencia respiratoria. La tomografía de tórax evidenció áreas de vidrio esmerilado difusas, patrón reticular y consolidación alveolar. Recibió tratamiento habitual para neumonía de la comunidad y corticoides sistémicos, presentando buena evolución y otorgándose el alta. Al mes se reinterna por estenosis subglótica, progresión de infiltrados pulmonares y aumento del volumen palpebral y de las glándulas submaxilares. Se realizaron biopsias transbronquial y de glándulas salivales que mostraron infiltración por IgG4. También se detectó aumento de los niveles de IgG4 en plasma. Recibió tratamiento con inmunosupresores evolucionando con buena respuesta.

RESUMO

El Ateneo Multicéntrico "EPID asociada a ANCA" publicado en el último número de la RAMR comenta el caso de un paciente con dicha asociación. Las patologías que padece el enfermo son comentadas con muy buen criterio clínico y estoy de acuerdo en todo lo que se dice. Sin embargo, me permito agregar y enfatizar algunos puntos. La combinación de Fibrosis Pulmonar (FP) y Vasculitis-ANCA (VAA) fue descripta por primera vez por Nada y col. en 1990 al reportar dos casos de FP y ANCA-P1 .

RESUMO

The diffuse cystic lung diseases (DCLDs) are a pathophysiologically heterogeneous processes characterized by the presence of multiple thin-walled, air-filled spaces within the pulmonary parenchyma. The most common causes of DCLD are lymphangioleiomyomatosis (LAM) and pulmonary Langerhans cell histiocytosis (PLCH). DCLD develops rarely as a result of malignancy, typically secondary to metastases from peripheral sarcomas and mesenchymal tumors. DCLD have also been reported in a variety of other metastatic disease such as adenocarcinoma. Our case describes a patient with DCLD as a result of metastatic colorectal adenocarcinoma.

RESUMO

The combination of pulmonary fibrosis and emphysema is a syndrome described in the last years, which has its own characteristics and it is not only the casual association between the two entities. The idiopathic pulmonary fibrosis is the most common type of pulmonary fibrosis. However other interstitial lung diseases could be part of this syndrome. Among them is the connective tissue disease-associated interstitial lung disease. We report a case of this syndrome associated with rheumatoid arthritis. It has the peculiarity that the connective disease became overt several years after the presentation of combined pulmonary fibrosis and emphysema syndrome, which is infrequently reported in the literature.

RESUMO

Introducción: Las enfermedades pulmonares intersticiales difusas (EPID) son un grupo de enfermedades raras que, si bien comparten ciertas características clínicas, tienen un pronóstico muy diferente. La fibrosis pulmonar idiopática (FPI) es la más prevalente en muchos países y su diagnóstico puede ser dificultoso. Luego de los resultados expuestos en el consenso sobre diagnóstico y manejo de la FPI, y la llegada de nuevas drogas como la pirfenidona, se ha modifcado el enfoque de esta enfermedad. Se realizó una encuesta a neumonólogos argentinos, con el fin de evaluar la aceptabilidad e implementación de estas guías en Argentina. Materiales y métodos: Se diseñó una encuesta con 24 preguntas. Entre los datos que se recolectaron en el cuestionario estaban demografía de los encuestados, lugar de trabajo (instituciones públicas, privadas, grandes o pequeños centros o instituciones), frecuencia con la que evaluaban pacientes con FPI, disponibilidad de pruebas diagnósticas y estrategias diagnósticas empleadas para pacientes con EPID. Por último, la encuesta se focalizó en las recomendaciones terapéuticas en los pacientes diagnosticados como FPI. Dicha encuesta fue completada durante el Congreso Argentino de Medicina Respiratoria que se realizó en el 2013 en la ciudad de Mendoza. La misma metodología y cuestionario fueron utilizados previamente en el Congreso Argentino de Medicina Respiratoria del 2011. Resultados: Un total de 252 médicos respondieron la encuesta en el 2013, lo que representó alrededor del 20% de los concurrentes al congreso. El método complementario de mayor disponibilidad fue la prueba de marcha de 6 minutos (PM6M). El método complementario más utilizado fue la tomografía computada de tórax (86.9% de los encuestados la realizaban ante la sospecha de EPID) y solo el 44.4% de los encuestados realizaban difusión de monóxido de carbono (DLCO) en todos sus pacientes. Cerca del 50% de los encuestados consultaban a centros de referencia en menos del 30% de sus casos con sospecha de EPID. Menos del 20% de los respondedores consideraban que llegaban a un diagnóstico defnitivo de EPID en más del 60% de sus pacientes. La distribución final de los diagnósticos fue heterogénea. Notablemente, casi el 50% de los encuestados consideraba que la FPI había sido el diagnóstico final en menos de 30% de sus pacientes. Solo el 30% de los encuestados prescribieron pirfenidona como tratamiento de elección en la FPI y más del 60% todavía continuaban prescribiendo tratamientos que incluían diferentes combinaciones de corticoides e inmunosupresores. Conclusiones: Nuestra encuesta sugiere que existen dificultades en el abordaje diagnóstico de estas entidades, que existe un bajo porcentaje de pacientes que son evaluados en centros de referencia y que hay una baja proporción de estos que reciben tratamiento específico.


Background: Diffuse interstitial (or parenchymal) lung diseases (ILDs) are a very large group of diseases that although they share certain clinical features, have a very different prognosis. Idiopathic pulmonary fibrosis (IPF) is the most prevalent in many countries and its diagnosis can be difficult. After the results shown in the consensus on diagnosis and management of IPF, and the arrival of new drugs such as pirfenidone, the approach to this disease have changed. A survey was performed to argentine pulmonologists in order to evaluate the acceptability and implementation of these guidelines in Argentina. Material and Methods: A survey of 24 questions was designed. Among the data collected in the questionnaire were demographics of respondents, workplace (public or private healthcare facilities, referral center, large or small healthcare centers or institutions), frequency at which IPF patients were examined, availability of diagnostic tests, and diagnostic strategies used with ILD patients. Finally, the survey focused on therapeutic recommendations for patients diagnosed with IPF. The survey was completed during the Argentine Congress of Respiratory Medicine held in 2013 in the city of Mendoza. The same methodology and questionnaire were previously used in the Argentine Congress of Respiratory Medicine in 2011. Results: In 2013, a total of 252 physicians completed the survey, which represented approximately 20% of Congress attendees. The complementary test of higher availability was the the six minutes walk test (6MWT). The most widely used supplementary method was thoracic computed tomography (CT) as 86.9% of the responders used it if they suspected ILD, and only 44.4% of the responders used diffusing capacity of the lungs for carbon monoxide (DLCO) with all their patients. Almost 50% of the responders consulted referral centers for less than 30% of patients with suspected ILD. Less than 20% of the responders considered that they reached a final diagnosis of ILD in over 60% of their patients. Final distribution of diagnosis was heterogeneous. Interestingly, almost 50% of the responders considered IPF as the fnal diagnosis in less than 30% of their patients. Approximately 50% of the responders answered that less than 20% of their IPF patients received specifc treatment for the disease. Conclusions: Our survey suggests that there are difficulties in the diagnostic approach of ILDs, there is a low percentage of patients that are evaluated in referral centers and there is a low proportion of IPF patients receiving specific treatment

RESUMO

La combinación de fibrosis pulmonar y enfisema es un síndrome descripto en los últimos años que tiene características propias y no es la casual asociación de dos entidades. El componente de fibrosis más común corresponde a la fibrosis pulmonar idiopática. Sin embargo, otras enfermedades intersticiales pueden formar parte de este síndrome, entre ellas las asociadas a enfermedades del tejido conectivo. Se presenta un caso de este síndrome asociado a artritis reumatoidea con la particularidad que la misma se hizo evidente varios años después del síndrome combinado fibrosis pulmonar y enfisema, hecho muy poco comunicado en la literatura.

The idiopathic pulmonary fibrosis is the most common type of pulmonary fibrosis. However other interstitial lung diseases could be part of this syndrome.

RESUMO

Microscopic polyangiitis (MPA) is a systemic necrotizing vasculitis characterised by inflammation of the small blood vessels, the absence of granulommas on histopathological specimens, with few or no immune deposits and the presence of circulating anti-neutrophil cytoplasmic antibodies (ANCAs). The classic pulmonary manifestation is diffuse alveolar haemorrhage (DAH), but its association with pulmonary fibrosis (PF) has been increasingly reported and may be the first manifestation of MPA. Our aim was to evaluate MPA patients with PF and compare their characteristics and evolution to those of MPA patients without PF. We conducted a retrospective review of MPA patients followed in our hospital over a 15-year period. They were divided into two subgroups, with PF (MPA-PF) and without PF (MPA-non PF), and their clinical and functional features were compared. Nine of the 28 patients were classified as MPA-PF (32%). This subgroup showed significantly more respiratory symptoms and higher mortality than MPA-non PF subgroup. The most frequent chest computed tomographic pattern of PF was usual interstitial pneumonia. PF preceded other manifestations of vasculitis in five patients and occurred simultaneously in the remaining four. During the follow-up period, four deaths were reported in the MPA-PF subgroup. No deaths were registered in the MPA-non PF subgroup. We found a high prevalence of MPA-PF patients (32%), most of whom had a poor outcome and PF was often the first manifestation of the disease.

RESUMO

The introduction of the anti-CD20 antibody rituximab into clinical practice has improved substantially the prognosis of a variety of haematological and autoimmune diseases. The interstitial lung disease is one of most serious and potentially fatal complications of rituximab therapy. This diagnosis should be considered in patients who have received the drug and present with dyspnea, fever and cough without clear evidence of infection. We report a case of rituximab-induced interstitial lung disease.

RESUMO

La introducción en la práctica clínica del anticuerpo anti-CD20 rituximab ha mejorado sustancialmente el pronóstico de diversas enfermedades autoinmunes y hematológicas. Con el incremento de su uso ha aumentado el registro de efectos adversos, entre ellos la toxicidad pulmonar. Una de sus complicaciones más serias es la enfermedad pulmonar intersticial, entidad potencialmente fatal que debe ser considerada en pacientes que han recibido rituximab y presentan disnea, fiebre y tos sin clara evidencia de infección. Presentamos un caso de enfermedad pulmonar intersticial asociada a rituximab.

RESUMO

The most frequently observed pulmonary complications of vasculitis (AAV) with anti-neutrophil cytoplasmic positive antibodies (ANCA) are alveolar hemorrhage, granulomas and airway stenosis. In recent years, some reports have been published that show the association of vasculitis with pulmonary fibrosis (PF), suggesting that it may be another complication of AAV. We report and describe here two cases with such association, and their clinical, tomographic and immunological characteristics. Given that in the association between PF and AAV, as reported in the last years, PF could be the first manifestation of AAV, the search for ANCA in patients with PF may be necessary, as a cause of it and for the possible subsequent development of vasculitis.

RESUMO

Las complicaciones pulmonares más conocidas de las vasculitis con anticuerpos anticitoplasmáticos de los neutrófilos (ANCA) positivos (VAA), son la hemorragia alveolar, los granulomas y la estenosis de la vía aérea. En los últimos años han aparecido algunos informes aislados que muestran la asociación con fibrosis pulmonar (FP), sugiriendo que ésta sería otra complicación de las VAA. En este trabajo informamos dos casos con dicha asociación describiendo sus características clínicas, tomográficas e inmunológicas. Dado que en la asociación de FP y VAA notificada en los últimos años, la FP puede ser su primera manifestación, podría ser necesaria la búsqueda de ANCA en pacientes con FP, como causa de la misma y por el posible desarrollo posterior de vasculitis.

RESUMO

Tuberculosis (TB) that affects lower lung fields (LLFTB) is infrequent in the adult population and is generally associated with immunodeficiency. The objective of our study was to determine the incidence of LLFTB in our patients population and compare the characteristics of these pa-tients with those who presented TB of typical pulmonary localization. We studied 42 patients with LLFTB retrospec-tively between 2004 and 2008 and compared them to 84 patients with TB of typical localization (control group). HIV-positive patients were excluded. LLFTB represented 6% of the pulmonary TB cases. No significant differences were found with respect to age, sex, the presence of cavities in chest x-rays, days of evolution, and albumin levels. LLFTB had a significantly greater proportion of comorbilities (p < 0.001), the presence of condensation (p < 0.001), and unilateral involvement (p < 0.001), with a higher number of hospital admissions (p = 0.02). The observation that only 16 of the 42 patients with LLFTB (38%) had a notable comorbility is important. Thus, LLFTB can be present without associated comorbilities and must be suspected in pneumonias that have a torpid evolution regardless of pulmonary localization.

RESUMO

La tuberculosis (TB) que compromete sólo los campos pulmonares inferiores (TBCI) es poco frecuente en el adulto y en general está asociada a alguna causa de inmunodepresión. El objetivo de nuestro trabajo fue determinar la incidencia de TBCI en nuestra población y comparar sus características respecto de la TB pulmonar de localización habitual. Se estudiaron en forma retrospectiva en el período de 2004 a 2008, 42 pacientes con TBCI que fueron comparados con 84 pacientes con TB pulmonar de localización habitual (grupo control). Se excluyeron pacientes con HIV. La TBCI representó el 6% del total de TB pulmonar. No se encontraron diferencias significativas en cuanto a edad, sexo, presencia de cavidades en la radiografía, días de evolución y nivel de albúmina. La TBCI tuvo significativamente mayor proporción de comorbilidades (p < 0.001), presencia de condensación (p < 0.001) y compromiso unilateral (p < 0.001) en la radiografía de tórax, junto con mayor número de internaciones (p = 0.02). Cabe destacar que sólo16 de los 42 pacientes con TBCI (38%) tenían alguna comorbilidad demostrada. La TBCI puede presentarse aun sin comorbilidades asociadas y debe sospecharse en neumonías de evolución tórpida independientemente de su localización.

RESUMO

Objetivos: Detectar en pacientes con Artritis Reumatoidea (RA) la presencia de enfermedad pulmonar intersticial asociada (RA-ILD), analizando los factores de riesgo reportados por la literatura y sus repercusiones clínico-funcionales. Material y métodos: Se estudiaron prospectivamente pacientes con el diagnóstico de RA buscando la presencia de RA-ILD por Tomografía Computada de Alta Resolución (TACAR).Se realizó en los mismos evaluación neumonológica y reumatológica, estudiosfuncionales respiratorios y se indagaron los factores de riesgo que se consideran asociados al desarrollo de RA-ILD. Se compararon los grupos con o sin ILD asociada. Resultados: Se reclutaron treinta y seis pacientes de los cuales en 11 se detectó compromiso intersticial (30.5%). Ni los síntomas respiratorios ni los factores de riesgo asociadosmostraron presencia significativa en el grupo con ILD. El grupo con RA-ILD mostró alteraciones funcionales significativas respecto al grupo sin ILD en la Difusión de CO (DLCO) y en la caída de Saturación de O2 (Sat. O2) en el test de marcha de 6 minutos (6MWT). Tres de los once pacientes con ILD (27%) no tuvieron alteraciones clínicas ni funcionales. Discusión: La RA-ILD detectada por TACAR no se asoció significativamente a ninguno de los factores de riesgo reportados. En concordancia con lo descripto en la literatura, vemos que el espectro de nuestro grupo de pacientes con RA-ILD detectada por TACAR puede ir desde serias manifestaciones respiratorias que aumentan la morbimortalidad de la RA hasta aquellos sin manifestaciones clínico-funcionales (RA-LD “preclínica”).El significado y la evolución de este último grupo no se conoce.


Objectives: To determine in patients with rheumatoid arthritis (RA) the prevalence of associated interstitial lung disease (RA-ILD), its risk factors and clinical-functional manifestations.Materials and methods: Patients with diagnosis of RA were prospectively studied searching for interstitial involvement on high resolution computerized tomography (HRCT). The research methods included pulmonary and rheumatoid evaluations, pulmonaryfunction tests and identification of risk factors considered to be associated to the development of ILD. Groups of RA patients with and without ILD were compared. Results: Among 36 RA patients included in the study, pulmonary interstitial involvementwas detected in 11 (30.5%). Neither respiratory symptoms nor risk factors had a significant presence in the group of patients with ILD in comparison with the group of patients without ILD. However, the RA-ILD group showed significant functional alterations, as evidenced in the test of diffusing capacity of the lung for carbon monoxide (DLCO) and the drop of the oxygen saturation in the 6 minute walk test. Three of the 11 RA-ILD patients (27%) did not have clinical or functional alterations. Discussion: RA-ILD detected on HRCT was not significantly associated to any of the risk factors reported. In agreement with the published literature, the clinical spectrum of the group of patients with RA-ILD involvement on HRCT varied from serious respiratory manifestations that increase RA morbidity and mortality to lack of clinical and functionalmanifestations (“preclinical” RA-ILD). The significance and prognosis of ILD involvement in this last group is unknown.

RESUMO

En el análisis de 318 pacientes con tuberculosis (TB) pulmonar activa, tratados entre enero de 1980 y diciembre de 1990, en un Hospital General del Gran Buenos Aires, el grupo (n = 48) con baciloscopía negativa (D-) tuvo diferencias clínicas y radiológicas significativas con respecto al grupo (n = 270) con baciioscopía positivia (D+). Estas diferencias fueron la mayor edad, la mayor frecuencia de otras enfermedades pulmonares y de Rx "secuela", con menos antecedentes clínicos y cavidades pulmonares radiológicas. Dos subgrupos se distinguem en el grupo D-, de acuerdo a la iniciación empírica del tratamiento. Por un lado un subgrupo con características similares al grupo D+, lo que facilitó la decisión de comenzarlo aún con la baciloscopía negativa (D-TI). El otro subgrupo tuvo características totalmente diferentes al grupo D+, lo que hizo pensar en otros diagnósticos, difiriendo así la decisión del tratamiento hasta la obtención del cultivo (D-TD).
