Abstract:

Objective To analyze the relationship between blood cell count-derived ratio parameters and rheumatoid arthritis (RA) and to explore their clinical diagnostic value. Methods The aggregate inflammation systemic index (AISI), neutrophil-to-lymphocyte ratio (NLR), derived NLR (dNLR), hemoglobin-to-lymphocyte ratio (HLR), hemoglobin-to-platelet ratio (HPR), lymphocyte-to-monocyte ratio (LMR), platelet-to-lymphocyte ratio (PLR), platelet-to-monocyte ratio (PMR), systemic immune-inflammatory index (SII), and systemic immune response index (SIRI) in 217 RA patients and 211 healthy individuals were collected and compared. The correlations between these parameters and clinical scores, as well as inflammatory and immune markers were investigated. Logistic regression analysis was used to determine the relationship between these ratio parameters and RA. Receiver operating characteristic (ROC) curves were used to evaluate their diagnostic values for RA. Results Compared to the healthy control group, PMR, LMR, HPR and HLR were significantly decreased (P<0.05), while erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), rheumatoid factor (RF), anti-mutated citrullinated vimentin antibody (aMCV), NLR, dNLR, PLR, SII, SIRI and AISI were significantly increased (P<0.05) in the RA group. DAS28 score was positively correlated with ESR, CRP, RF, aMCV, and PLR, while negatively correlated with HPR (P<0.05). Multivariate Logistic regression analysis showed that high levels of ESR, CRP, RF, ASO and PLR were independent risk factors for the occurrence of RA, while high levels of PMR and HLR were protective factors (P<0.05). The combined detection based on ESR, CRP, RF, ASO, PLR, PMR and HLR showed better performance in the diagnosis of RA compared to individual parameters, with an area under the curve (AUC) of 0.889 (95%CI: 0.852-0.927). Conclusion PLR and HPR are associated with the clinical activity of RA. The multi-index combined detection provides a new approach for the auxiliary diagnosis of RA.
