RESUMEN

INTRODUCCIÓN:

Las Vasculitis Asociadas a Anticuerpos Anticitoplasma de Neutrófilos (VAA) son infrecuentes, pero de amplio espectro de presentación. Si bien el consenso de clasificación de Chapel Hill del año 2012, sigue vigente, la tendencia actual es clasificarlas de acuerdo al marcador inmunológico anti-Proteinasa 3 (PR3) o anti-mieloperoxidasa (MPO). Las manifestaciones pulmonares clásicas son la hemorragia alveolar y los nódulos pulmonares. En los últimos 10 años se ha descrito la enfermedad pulmonar difusa (EPD). Los estudios epidemiológicos son escasos, y suelen representar en su mayoría poblaciones norteamericanas o europeas. El objetivo es describir las características del compromiso pulmonar al debut en VAA en un centro universitario. PACIENTES Y

MÉTODO:

De un total de 190 pacientes con diagnóstico de VAA se incluyeron 170 en seguimiento en nuestro centro. Se revisaron aspectos clínicos, demográficos, laboratorio e imagenológicos de los pacientes incluidos.

RESULTADOS:

De los 170 pacientes, 112 (65,88%) presentaron compromiso pulmonar. 106 (94,64%) de los pacientes fueron anticuerpos anti citoplasma de neutrófilos (ANCA) positivos; de estos, 56 (53,27%) MPO (+) y 39 (36,45%) PR-3 (+). Un tercio de los pacientes de ambos grupos presentó hemorragia alveolar. En los pacientes MPO (+) predomina la EPD (53,5%) y en PR-3 (+) los nódulos pulmonares (69,23%). Destaca la baja frecuencia de patología obstructiva asociada.

CONCLUSIONES:

El compromiso pulmonar en las VAA es prevalente y heterogéneo. En nuestra serie, destaca la frecuencia de EPD en VAA MPO (+), lo que releva la importancia del estudio con ANCA en paciente con diagnóstico y seguimiento por EPD.
ABSTRACT

INTRODUCTION:

Antineutrophil Cytoplasmic Antibodies (ANCA) associated vasculitis (AAV) are uncommon, but of broad spectrum of presentation. Although the 2012 Chapel Hill classification consensus remains valid, the current trend is to classify them according to the immunological marker anti-Proteinase 3 antibody (PR-3) or anti-Myeloperoxidase antibody (MPO). The classic pulmonary manifestations are alveolar hemorrhage and pulmonary nodules. Interstitial lung disease (ILD) has been described in the last 10 years. Epidemiological studies are scarce, and they usually represent mostly North American or European populations. The objective is to describe the characteristics of lung involvement upon debut in AAV in a university center. PATIENTS AND

METHODS:

Of a total of 190 patients diagnosed with AAV, 170 were included in follow-up at our center. Clinical, demographic, laboratory and imaging aspects of the included patients were reviewed.

RESULTS:

Of the 170 patients, 112 (65.88%) had lung involvement. 106 (94.64%) of the patients were ANCA (+); of these, 56 (53.27%) MPO (+) and 39 (36.45%) PR-3 (+). One third of the patients in both groups had alveolar hemorrhage. In MPO (+) patients, ILD predominates (53.5%) and in PR-3 (+) pulmonary nodules (69.23%). The low frequency of associated obstructive pathology stands out.

CONCLUSIONS:

Pulmonary manifestations in AAVs are frequent and heterogeneous. Locally, the association of ILD and AAV MPO (+) stands out, which highlights the importance of ANCA study in patients with diagnosis and follow-up by ILD.
