Abstract:
Objective:To investigate the correlation of systemic immune inflammatory index (SII) and monocyte-to-lymphocyte ratio (MLR) with chronic kidney disease-mineral and bone disorder (CKD-MBD) in patients with stage 5 chronic kidney disease (CKD).Methods:A cross-sectional survey method was used to select 152 patients with stage 5 CKD who received treatment in the Department of Nephrology, Hefei First People's Hospital from January 2023 to January 2024 as research subjects. Based on the patients' intact parathyroid hormone (iPTH) levels, they were divided into three groups: low iPTH group ( n = 63), normal iPTH group ( n = 46), and high iPTH group ( n = 43). The differences in SII and MLR among the three groups were analyzed. The relationship between SII and the occurrence of high iPTH was analyzed to assess the predictive efficacy of SII for high iPTH. Results:Among the 152 patients with stage 5 CKD, the low iPTH group accounted for 41.45% (63/152), the normal iPTH group for 30.26% (46/152), and the high iPTH group for 28.29% (43/152). The prevalence of hypertension in each group was as follows: 85.71% (54/63) in the low iPTH group, 89.13% (41/46) in the normal iPTH group, and 60.77% (30/43) in the high iPTH group ( χ2 = 6.60, P = 0.037). Other parameters showed significant differences among the groups: neutrophil count was 3.60 (2.94, 4.79) × 10 9/L in the low iPTH group, 4.08 (3.16, 4.88) × 10 9/L in the normal iPTH group, and 5.21 (4.08, 6.75) ×10 9/L in the high iPTH group ( Z = 25.64, P < 0.001); lymphocyte count was 1.51 (1.13, 1.85) × 10 9/L, 1.18 (1.00, 1.68) × 10 9/L, and 1.10 (0.75, 1.66) × 10 9/L, respectively ( Z = 8.25, P = 0.016); monocyte count was 0.47 (0.36, 0.62) × 10 9/L, 0.53 (0.42, 0.70) × 10 9/L, and 0.43 (0.33, 0.54) × 10 9/L, respectively ( Z = 8.15, P = 0.017); serum albumin levels were (37.26 ± 5.77) g/L, (36.31 ± 5.68) g/L, and (41.53 ± 4.90) g/L, respectively ( t = 10.85, P < 0.001); creatinine levels were 214.00 (148.00, 343.00) μmol/L, 462.00 (338.50, 682.25) μmol/L, and 835.50 (702.50, 960.75) μmol/L, respectively ( Z = 74.65, P < 0.001); serum calcium levels were 2.19 (2.11, 2.28) mmol/L, 2.16 (2.04, 2.26) mmol/L, and 2.32 (2.10, 2.49) mmol/L, respectively ( Z = 11.77, P = 0.003); serum phosphate levels were 1.21 (1.04, 1.49) mmol/L, 1.47 (1.27, 1.83) mmol/L, and 1.99 (1.65, 2.49) mmol/L, respectively ( Z = 48.72, P < 0.001); SII values were 362.75 (292.68, 639.92), 491.03 (380.12, 715.77), and 851.50 (525.23, 1 149.72), respectively ( Z = 33.02, P < 0.001); and MLR values were 0.30 (0.24, 0.43), 0.43 (0.30, 0.52), and 0.35 (0.28, 0.61), respectively ( Z = 9.02, P = 0.011). All differences among the three groups were statistically significant (all P < 0.05). There were no statistically significant differences among the groups regarding age, gender, height, body mass index, smoking history, alcohol consumption history, prevalence of diabetes, platelet count, serum total protein, uric acid, triglycerides, total cholesterol, high-density lipoprotein cholesterol, or low-density lipoprotein cholesterol (all P > 0.05). Multivariate logistic regression analysis indicated that elevated SII ( OR = 1.003, P = 0.024) was an independent risk factor for increased serum iPTH ( P < 0.05). Receiver operating characteristic analysis showed that the area under the curve for SII predicting high iPTH in patients with stage 5 CKD was 0.774 ( P < 0.001). Conclusions:In patients with stage 5 CKD, elevated creatinine, serum calcium, and SII are independent risk factors for increased serum iPTH, and SII has predictive value for the occurrence of high iPTH in patients with CKD.
