Association between clinical variables and mortality after parathyroidectomy in maintenance hemodialysis patients

We investigated factors associated with all-cause mortality and cardiovascular disease (CVD)-associated mortality after parathyroidectomy (PTX) in patients on maintenance hemodialysis (HD).

Our study population consisted of 161 consecutive HD patients who underwent PTX before 2009 and 354 consecutive HD patients without PTX as controls from those visiting the Kaohsiung Chang Gung Memorial Hospital, Taiwan between 2009 and 2013. All-cause and CVD mortality with clinical variables were compared in PTX and non-PTX HD patients.

PTX patients had significantly lower all-cause and CVD mortality than controls. Multivariate logistic regression analyses showed PTX patients had a lower odds ratio for all-cause mortality than those without (odds ratio = .35, 95% confidence interval = .16 to .74). Association analysis based on clinical variables revealed patients with higher hemoglobin, albumin, creatinine, and HD adequacy index-Kt/V levels had significantly decreased risk of all-cause mortality.

PTX in HD patients reduces the risk of death.
