(Dis) Agreement between the first and the recent European consensus on definition and diagnosis for sarcopenia in kidney transplant patients

Abstract

We previously detected that ~50% of kidney transplant patients (KTPs) present sarcopenia using the first European Working Group on Sarcopenia in Older People (EWGSOP1) consensus. Our aim was to evaluate the agreement between the sarcopenia diagnosis using EWGSOP1 and the new consensus (EWGSOP2) in KTPs. A cross-sectional study was performed evaluating 127 KTPs. Total and appendicular muscle mass were estimated by bioelectrical impedance. Strength was evaluated by handgrip strength (HGS) and five times sit to stand (5STS). Functional capacity was evaluated by 4-m walk test and short physical performance battery. Sarcopenia was diagnosed by EWGSOP1 and EWGSOP2. The agreement between EWGSOP1 and EWGSOP2 (using HGS criteria for muscle strength) was fair (k = 0.341–0.402). Slight agreement was observed between EWGSOP1 and EWGSOP2 using 5STS criteria for muscle strength (k = 0.031–0.046). We conclude that EWGSOP2 definitions have a low agreement with EWGSOP1 in KTPs.
