ABSTRACT
Objective:To investigate the relationship between protein-energy wasting (PEW) and parathyroid hormone (PTH) levels in patients undergoing maintenance hemodialysis.Methods:A cross-sectional study was conducted to enroll 150 adult patients undergoing maintenance hemodialysis at The Third Affiliated Hospital of Anhui Medical University from January 2022 to May 2023. These patients were categorized into four groups based on their PTH levels: low PTH group (< 150 ng/L), standard PTH group (150-300 ng/L), very high PTH group (300-600 ng/L), and extreme high PTH group (> 600 ng/L). The diagnosis of PEW was determined using the diagnostic criteria proposed by the International Society of Renal Nutrition and Metabolism (ISRNM). Logistic regression analysis was performed to investigate the association between PEW and PTH levels.Results:Among the 150 patients undergoing maintenance dialysis, 52 (34.7%) were diagnosed with PEW. The prevalence of PEW was significantly higher in the low PTH group compared with the standard, very high, and extreme high PTH groups ( χ2 = 20.64, all P < 0.05). Univariate logistic regression analysis revealed a strong association between low PTH levels ( OR = 13.810, 95% CI: 2.907-65.603, P = 0.001) and an increased risk of PEW. The risk of PEW in the low PTH group was 13.810 times higher than that in the extreme high PTH group. Multivariate logistic regression analysis further confirmed that low PTH levels ( OR = 19.891, 95% CI: 1.810-218.620, P = 0.014) and low C-reactive protein levels ( OR = 1.056, 95% CI: 1.015-1.099, P = 0.007) were independently associated with an increased risk of PEW. Higher hemoglobin levels ( OR = 0.959, 95% CI: 0.931-0.988, P = 0.005) and a larger middle upper arm circumference ( OR = 0.544, 95% CI: 0.338-0.875, P = 0.012) were independently associated with a reduced risk of PEW. The risk of PEW in the low PTH group was 19.891 times higher than that in the extreme high PTH group. However, there was no significant difference in the risk of PEW in the standard and very high PTH groups compared with the extreme high PTH group (both P > 0.05). Conclusion:The risk of PEW is markedly elevated in patients with low PTH levels, emphasizing the importance of clinical attention to the prevention and treatment of low PTH levels. Addressing this issue may hold great value in reducing the risk of PEW.
