Abstract
Introduction

Serum biomarkers are important predictive factors for development of parotid non-Hodgkin's lymphoma (NHL) complication in primary Sjogren's syndrome (pSS) patients. The aim was to evaluate the diagnostic accuracy of serum CXCL13 chemokine in pSS patients with parotid NHL complication.

Material and methods

Serum CXCL13 chemokine was assessed in 33 patients with pSS [7 with parotid NHL complication (pSS+NHL subgroup) and 26 without NHL (pSS-NHL subgroup)] and 30 healthy subjects.

Results

The serum CXCL13 levels in pSS+NHL subgroup [175.2 (107.9–220.4) pg/ml] were significantly higher comparing to the healthy subjects group (p=0.018) and the pSS-NHL subgroup (p=0.048). A cut-off value of 123.45pg/ml (Se=71.4%, Sp=80.8%, AUROC=0.747) was established for parotid lymphoma diagnosis.

Conclusion

The serum CXCL13 biomarker could be considered a valuable tool for the diagnosis of parotid NHL complication in pSS patients.

Resumen
Introducción

Los biomarcadores séricos son factores predictivos importantes para el desarrollo de complicaciones del linfoma no Hodgkin (LNH) parotídeo en pacientes con síndrome de Sjogren primario (SSp). El objetivo fue evaluar la precisión diagnóstica de la quimiocina sérica CXCL13 en pacientes con SSp con complicación del LNH parotídeo.

Material y métodos

Se evaluó la quimiocina sérica CXCL13 en 33 pacientes con SSp [7 con complicación de LNH parotídeo (subgrupo SSp+LNH) y 26 sin LNH (subgrupo SSp-LNH)] y 30 sujetos sanos.

Resultados

Los niveles séricos de CXCL13 en el subgrupo pSS+NHL [175,2 (107,9-220,4) pg/ml] fueron significativamente más altos en comparación con el grupo de sujetos sanos (p=0,018) y el subgrupo pSS-NHL (p=0,048). Se estableció un valor de corte de 123,45 pg/ml (Se=71,4%, Sp=80,8%, AUROC=0,747) para el diagnóstico de linfoma de parótida.

Conclusión

El biomarcador sérico CXCL13 podría considerarse una herramienta valiosa para el diagnóstico de la complicación del LNH parotídeo en pacientes con SSp.
