RESUMEN
Antecedentes y

objetivo:

Las enfermedades autoinmunes se presentan asociadas, con una alta incidencia, en los pacientes con inmunodeficiencia común variable (IDCV), respecto a la población normal. El objetivo de este estudio fue describir los hechos clínicos del fenotipo autoinmune en pacientes con IDCV.

Métodos:

Se revisaron las historias clínicas de todos los pacientes diagnosticados de IDCV del Medical Center Hospital de Teherán en el periodo de 2000-2010. Los pacientes fueron clasificados en dos grupos con y sin enfermedades autoinmunes asociadas.

Resultados:

De los 52 pacientes estudiados, un 26.9% (14 pacientes) habían mostrado al menos una manifestación de enfermedad autoinmune durante el tiempo del estudio. Las citopenias autoinmunes y la artritis reumatoide juvenil fueron las manifestaciones más frecuentes en nuestra serie. Encontramos en nuestros pacientes asociaciones significativas entre enfermedades infiltrativas polilinfocíticas (p=0.017), incremento de niveles de IgM sérica (p<0.001) y disminución de cifras de IgE (p=0.04) con desarrollo de autoinmunidad, así como una disminución de las células B memoria (p<0.001).

Conclusión:

La autoinmunidad puede considerarse una de las manifestaciones iniciales en los pacientes con IDCV, por lo que se aconseja explorar el sistema inmunológico humoral mediante test in vitro, en aquellos pacientes con historias de infecciones de repetición. Por otra parte la presencia de enfermedades infiltrativas polilinfocíticas y la disminución de las células B memoria en pacientes con IDCV, pueden predisponer al desarrollo de una enfermedad autoinmune (AU)
ABSTRACT
Background and

objective:

Autoimmune disorders occur with a higher incidence in common variable immunodeficiency (CVID) patients than in the general population. To describe the clinical features of the autoimmune phenotype in patients with CVID.

Methods:

The hospital records of all diagnosed CVID patients referred to the Children’s Medical Center Hospital in Tehran, Iran between 2000 and 2010 were reviewed. Patients were also classified according to the presence or absence of autoimmune disease.

Results:

Of 52 patients studied, 26.9% (n=14) had shown at least 1 autoimmune manifestation during the study period. Autoimmune cytopenias and juvenile rheumatoid arthritis were the most common form of autoimmunity in our series. Autoimmunity was significantly associated with polyclonal lymphocytic infiltrative disorders (P=.017), increased serum Immunoglobulin (Ig) M levels (P<.001), decreased IgE values (P=.04) and diminished switched memory B-cell count (P<.001).

Conclusions:

Because autoimmunity is one of the first manifestations in CVID, humoral immune system tests should be considered in autoimmune patients with a history of recurrent infection. The presence of polyclonal lymphocytic infiltrative disorders and decreased switched memory B-cells may predispose CVID patients to autoimmunity (AU)
