Protein-energy wasting (PEW) is common in patients with kidney failure and predicts poor outcomes. Recent clinical trials have linked hyperparathyroidism to PEW. The present retrospective cohort study examined whether parathyroidectomy was associated with improvement in nutritional status in maintenance hemodialysis patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and methods<\/jats:title>\n                    <jats:p>One hundred twenty-nine maintenance hemodialysis patients who had successful parathyroidectomy during 2012\u20132018 were identified (PTX group) and matched 1:1 to 479 patients with parathyroid hormone (PTH) levels \u22641,000\u2009pg.\/mL (non-PTX control group) and 187 patients with PTH levels &amp;gt;1,000\u2009pg.\/mL (pre-PTX control group) by propensity score. The matchings yielded 120 matched pairs from PTX and non-PTX groups (cohort 1) and 76 matched pairs from PTX and pre-PTX groups (cohort 2). Baseline and follow-up nutritional parameters associated with PEW were compared over the 12-month study period.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      In cohort 1, substantially lower serum albumin and serum creatinine\/body surface area (Cr\/BSA) and higher proportions of patients with serum albumin \u226438\u2009g\/L (low albumin) and serum Cr\/BSA \u2264380\u2009\u03bcmol\/L\/m\n                      <jats:sup>2<\/jats:sup>\n                      (low Cr\/BSA) were observed in the PTX group.

The percentage of patients with low TLC became lower in the PTX group. Mixed-models analysis confirmed significant differences in the changes in serum albumin, serum Cr\/BSA, and proportions of patients with low albumin and TLC between the two groups.
