Correlation of anti-heat shock protein 70 antibodies serum level with malnutrition–inflammation score in hemodialysis patients

Increased levels of circulating heat shock protein 70 antibodies (anti-Hsp70) have been reported in hemodialysis (HD) patients. Since the anti-Hsp70 correlates with inflammation, it may associate with the malnutrition–inflammation score (MIS). The aim of this study was to determine whether the increased MIS score in HD patients are related to circulating levels of anti-Hsp70.
Ninety HD patients with an arteriovenous fistula, aged 30–65 years, who underwent three hemodialysis sessions a week for at least the past 3 months at a hemodialysis center were enrolled in this cross-sectional study. Patients were divided based on MIS score to two groups, and the clinical and biochemical variables were compared between them. MIS cutoff score of ≥ 5 indicated the presence of malnutrition. The association between categorized MIS and anti-Hsp70 was examined using regression models adjusted for diabetes mellitus, hemodialysis vintage, BMI, albumin, hs-CRP, IL6 and endotoxin levels as confounding factors.
The univariate regression analysis revealed a significant association between MIS ≥ 5 and hemodialysis vintage, uric acid, hs-CRP, IL-6, endotoxin and serum anti-Hsp70 level. After adjusting the confounders, the association between MIS ≥ 5 and serum anti-Hsp70 level remained significant.
These data support the role of serum anti-Hsp70 in the development of malnutrition in HD patients. However, further studies with body composition assessments and better generalizability are required to investigate the association between nutritional status and circulating anti-Hsp70 level in HD patients.
