Relationship between MELD severity score and the distance walked and respiratory muscle strength in candidates for liver transplantation.
The model end-stage liver disease (MELD) severity scoring system is used in the allocation of organs for liver transplantation. However, there is no evidence of its relationship with the functionality and respiratory muscle strength in these patients. The aim of this study was to analyze the correlation of MELD with distance walked and respiratory muscle strength in patients awaiting liver transplantation. We performed a cross-sectional analysis of 24 individuals (16 male and 8 female) with mean age of 51.8 +/- 10.4 years. The MELD score inversely correlated with the 6-minute walking test (6MWT) (r = -0.85; P < .001) and with the maximal inspiratory pressure (MIP) (r = -0.69; P < .001). In addition, there was a correlation between 6MWT and MIP (r = 0.77; P < .001). Thus, MELD scores can be considered to be effective tools to predict the functional capacity and respiratory muscle strength in candidates for liver transplantation.
