Research Article: Associations of systemic immune-inflammation index and aggregate index of systemic inflammation with acute gouty arthritis in men: a cross-sectional study
Abstract:
This study aims to evaluate the associations of complete blood cell count-derived inflammatory markers—including monocyte-to-lymphocyte ratio (MLR), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), Systemic Immune-Inflammation Index (SII), systemic inflammatory response index (SIRI), and aggregate index of systemic inflammation (AISI)—with acute gouty arthritis in males.
A cross-sectional study was conducted in 380 males from the Department of Endocrinology and Department of Physical Examination, Central Hospital of Dalian University of Technology, between January 2022 and January 2024. Multivariable logistic regression models were used to investigate the independent associations between six inflammatory markers and acute gouty arthritis. Restricted cubic splines (RCS) were employed to model the dose–response relationships of inflammatory markers with acute gouty arthritis. Subgroup analyses were performed to identify susceptible populations. The diagnostic capabilities of the inflammatory markers were evaluated and compared using receiver operating characteristic (ROC) curves.
A total of 380 male participants were included, with a mean age of 54?years. Among them, 108 participants had AGA, giving a prevalence of 28.4%. Significant associations with AGA were observed for monocyte-to-lymphocyte ratio (MLR), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), Systemic Immune-Inflammation Index (SII), systemic inflammatory response index (SIRI), and aggregate index of systemic inflammation (AISI). Further analysis using RCS revealed nonlinear dose–response relationships between SII and AGA ( p -nonlinear?=?0.001), as well as between AISI and AGA ( p -nonlinear <0.001). Subgroup analysis showed that inflammatory markers (NLR, PLR, SII, SIRI, and AISI) were more effective in assessing AGA onset among men with fatty liver. ROC analysis indicated that when compared with other inflammatory markers (MLR, NLR, PLR, and SIRI), SII and AISI demonstrated superior diagnostic accuracy and discriminatory power in assessing the risk of AGA in men.
In men, AGA is closely associated with inflammatory markers. In addition, compared with other inflammatory markers (MLR, NLR, PLR, and SIRI), SII and AISI may serve as more accurate indicators for the diagnosis of AGA.
Introduction:
Gout affects individuals worldwide, with a rising prevalence among younger populations ( 1 ). Acute gouty arthritis (AGA) is an inflammatory disorder defined by hyperuricemia and the deposition of monosodium urate (MSU) crystals in joints and tissues ( 2 ). The acute phase is typically characterized by an abrupt onset, manifesting as severe joint pain, cutaneous erythema, elevated skin temperature, and joint swelling. Recurrent acute gout attacks may progress to chronic gouty arthritis and tophus formation after…
