RESUMEN
Antecedentes: La inmunodeficiencia común variable (IDCV) constituye un grupo heterogéneo de alteraciones caracterizado por una disminución en el nivel de inmunoglobulinas séricas y un incremento en la susceptibilidad para sufrir infecciones bacterianas recurrentes. Existen evidencias que confirman que los pacientes con IDCV muestran una alteración del balance Th1/Th2 hacia una respuesta tipo Th1. En este estudio cuantificamos los niveles de CD26 soluble (sCD26) y CD30 (sCD30) como posibles marcadores de una respuesta inmune alterada en un grupo de pacientes con IDCV. Métodos: Se incluyeron 25 pacientes con IDCV y controles con edad y sexo similar, a los que se cuantificó mediante un ELISA los niveles de CD26 soluble y CD30. Resultados: Los niveles medios de sCD26 en pacientes con IDCV fueron 88.47±59.82 ng/mL, significativamente más altos que en los controles 28.31±25.61 ng/mL (p =0.001). Los niveles de sCD30 en pacientes con IDCV fueron también mayores que en los controles (196.37±169.71 ng/mL vs. 30.72±12.98 ng/mL, p <0.001). El análisis de los niveles de sCD30 en asociación con diferentes variables clínicas indicaron que los pacientes con esplenomegalia y neoplasias eran más altos en comparación con los que no presentaban estas asociaciones. No se encontraron asociaciones de los niveles de sCD30 con la presencia de bronquiectasias o autoinmunidad. Conclusiones: La elevación de sCD26 y sCD30 en pacientes con IDCV podría sugerir la hipótesis de una respuesta inmune polarizada al fenotipo Th1, y la asociación de niveles elevados de estos marcadores con la severidad de la enfermedad puede involucrar a estos marcadores como una herramienta útil en el pronóstico de la IDCV (AU)
ABSTRACT
Background: Common variable immunodefi ciency (CVID) is a heterogeneous group of disorders characterized by decreased serum immunoglobulin levels and increased susceptibility to recurrent bacterial infections. There is increasing evidence that the type 1 helper T cell (TH1)/TH2 cell balance is shifted towards a TH1-type immune response in patients with CVID. This study was performed to measure levels of soluble CD26 (sCD26) and CD30 (sCD30) as plausible markers of a dysregulated immune response in a group of patients with CVID. Methods: Twenty-five patients with CVID and 20 age- and sex-matched controls were enrolled in this study. A sandwich enzyme-linked immunosorbent assay was used to measure serum sCD26 and sCD30 levels. Results: The mean (SD) serum sCD26 level was significantly higher in patients with CVID than in controls (88.47 [59.82] ng/mL vs 28.31 [25.61] ng/mL, P=.001). Serum sCD30 levels were also significantly higher in patients with CVID than in controls (196.37 [169.71] ng/mL vs 30.72 [12.98] ng/mL, P<.001). Analysis of serum sCD30 levels in association with different clinical variables indicated that patients with splenomegaly and malignancy had significantly higher levels than patients without these disorders. However, serum sCD30 levels did not differ with bronchiectasis or autoimmunity. Conclusions: The presence of increased serum levels of sCD26 and sCD30 in patients with CVID suggests that CVID patients have a polarized immune response towards a TH1-like phenotype, whereas the association between high levels of these markers and disease severity suggests that the soluble form could be used as a prognostic tool in CVID (AU)
