Abstract:
Objective To investigate the effects of parathyroid hormone(PTH)on microinflammatory and nutritional status in maintenance hemodialysis(MHD)patients.Methods Ninety-eight MHD patients were selected,who hod undergone hemodialysis for at least three months before the study and were in a stable clinical status without signs of infection or disease activity.The serum level of intact PTH was measured by electrochemiluminescence immunoassay(ECLIA),while the serum levels of interleukin(IL)-1β,IL-6,IL-8 and tumor necrosis factor-α(TNF-α)were detected by enzyme-linked immunosorbent assay(ELISA).The levels of C-reactive protein(CRP),albumin(Alb),pre-albumin(PA),hemoglobin(Hb)and lipids were measured.Body measurement and modified quantitative subjective global assessment(MQSGA)was done simultaneously.Correlation analysis between serum PTH level and the parameters for inflammation and nutrition Was performed.Results The serum levels of intact PTH in MHD patients[(353.46±102.41)ng/L]were significantly higher than those in the control people[(57.45±5.76)ng/L,P<0.01],and the serum levels of IL-1β,IL-6,IL-8,TNF-α and CRP were significantly higher in MHD patients than those in the control people(P<0.01 or <0.05).Relative body weight(RBW),triceps skin fold thickness(TSF),mid-arm circumference(MAC)and mid-arm muscle circumference(MAMC)in MHD patients decreased significantly(P<0.05 or <0.01),while the score of MQSGA increased markedly(P<0.01).The levels of intact PTH showed significantly positive correlations with the levels of CRP,IL-1β, IL-6,TNF-α, lipoprotein(a) [Lp(a)] , serum phosphorus and ages of MHD(P<0.05 or <0.01 ).The levels of intact PTH showed significantly negative correlations with RBW, MAC, MAMC, Alb, Hb and total cholesterol(TC) in MHD patients (P<0.01 or <0.05) . And there was also significantly positive correlation between PTH and MQSGA in MHD patients (P<0.05). Conclusion PTH is probably involved in the presence and the progression of malnutrition-inflammation-atherosclerosis syndrome in MHD patients.
