Abstract
Objective

To evaluate the correlation of different hematological parameters in lupus patients with SLE disease activity index (SLEDAI), the Systemic Lupus International Collaboration Clinics/American College of Rheumatology Damage Index (SLICC/ACR DI), and some laboratory data related to kidney functions in active patients with nephritis.

Material and methods

80 inactive SLE patients (SLEDAI score<10 points), and 80 active patients (SLEDAI10 points) were enrolled in this study. All patients underwent full medical history taking, clinical evaluation including calculation of SLEDAI and SLICC/ACR DI scores, and laboratory investigations including complete blood count. The two groups were compared regarding different disease parameters. Correlations of some hematological parameters with SLEDAI, SLICC/ACR DI scores and some laboratory data related to kidney function in patients with nephritis were made.

Results

The active group showed statistically significantly higher mean NLR (P=0.000), NC3R (P=0.000), MLR (P=0.000), PLR (P=0.000), and RDW (P=0.001), and statistically significantly lower mean MPV (P=0.002). The mean MLR (P=0.018) and PLR (P=0.005) were statistically significantly higher in the active patients with nephritis. For both groups, there were no significant correlations between studied parameters and SLEDAI or SLICC/ACR DI, except with NC3R values in the active group which were associated with SLEDAI (r=.221, P=0.049).

Conclusion

The hematological parameters in SLE have promising potential clinical application as a novel activity marker, especially in patients with nephritis.

Resumen
Objetivo

Evaluar la correlación de diferentes parámetros hematológicos en pacientes con lupus con el índice de actividad de la enfermedad del LES (SLEDAI), el Systemic Lupus International Collaboration Clinics/American College of Rheumatology Damage Index (SLICC/ACR DI y algunos datos de laboratorio relacionados con la función renal en pacientes activos con nefritis.

Material y métodos

Ochenta pacientes con LES inactivos (puntuación SLEDAI < 10 puntos) y 80 pacientes activos (SLEDAI ≥ 10 puntos) se inscribieron en este estudio. Todos los pacientes se sometieron a una historia clínica completa, evaluación clínica, incluido el cálculo de las puntuaciones SLEDAI y SLICC/ACR DI, e investigaciones de laboratorio, incluido un hemograma completo. Se hizo una comparación entre los dos grupos con respecto a diferentes parámetros de la enfermedad. Se realizaron correlaciones de algunos parámetros hematológicos con las puntuaciones SLEDAI, SLICC/ACR DI y algunos datos de laboratorio relacionados con la función renal en pacientes con nefritis.

Resultados

El grupo activo mostró una media estadísticamente significativamente más alta de NLR (P=0,000), NC3R (P=0,000), MLR (P=0,000), PLR (P=0,000) y RDW (P=0,001) y una media estadísticamente significativamente más baja de VPM (P=0,002). La media de MLR (P=0,018) y PLR (P=0,005) fue significativamente mayor desde el punto de vista estadístico en los pacientes activos con nefritis. Para ambos grupos, no hubo correlaciones significativas entre los parámetros estudiados y SLEDAI o SLICC/ACR DI, excepto con los valores de NC3R en el grupo activo que se asoció con SLEDAI (r=0,221, P=0,049).

Conclusión

Los parámetros hematológicos en el LES tienen una aplicación clínica potencial prometedora como marcador de actividad novedoso, especialmente en pacientes con nefritis.
