Avaliação da capacidade de exercício, função pulmonar e qualidade de vida em pacientes com insuficiência renal crônica




The Chronic Kidney Disease (CKD) can affect all organic systems, that evolve with some complications like uremic miopathy, anemia and secondary hyperparathyroidism. This complication has been associated with symptoms like weakness and functional impairment. The aim of this study was to evaluate pulmonary function, exercise capacity and quality of life in the patients with CKD. There were evaluated 72 subjects: 32 patients with CKD (DG), 10 patients post renal transplantation (TG) and 30 normal subjects that was called control group (CG). The DG group has been on hemodialysis treatment during at least 6 months, 43,9 (2,3) years, 65,9 (2,2) Kg and 1,67 (0,01) meters. The TG group has done the renal transplantation at least 6 months and have to be clinically stable, 50,4 (2,7) years, 75,2 (5,1) Kg and 1,7 (0,02) meters. The CG group, 48,4 (2,6) years, 71,7 (2,2) Kg and 1,67 (0,01) meters, must not be respiratory, cardiac or others that can impaired the evaluated variables. The pulmonary function was evaluated by spirometry according to American Thoracic Society (1995), by maximal inspiratory pressure (MIP) and expiratory pressure (MEP) according to Black and Hyatt protocol (1969) and by chest wall motion using an adaptation from Kakisaki (1999) methods. The exercise capacity was measured using the six minute walking test (6MWT) according to American Thoraci Society (2002). The quality of life was measured using SF-36 questionnaire to DG and TG groups. There were analyzed the exams from DG group. Al values was showed with mean (standard error). The statistical analysis were done using one way ANOVA and Student t test for normal distribution sample. Mann-Whitney e Kruskall-Wallis tests for unormal distribution sample. Qui-square test for association between variables and groups and Pearsons correlation between functional variables. All test has considered p<0,05 to minimum statistical significant level. The results showed statistical different values to: reduction of pulmonary function (FVC, FEV1, MVV, VC, MIP, MEP) in DG and TG groups; association between MIP reduction and DG group; exercise capacity reduction (6MWT) in DG and TG groups. There were not found differences in functional parameters when classifying DG group by exams results. There were not differences between DG and TG group in SF-36 analysis; however the mean values were under the normal values expected for normal population. We found significative correlations (p<0,05) in DG group between FVC and 6MWT (r=0,355), FVC and e Total from SF-36 (r=0,414), FVC and MVV (r=0,469), 6MWT and Total from SF-36 (r=0,439), 6MWT and Physical Functioning (r=0,708), MVV and Total from SF-36 (r=0,348), MIP and MEP (r=0,548). We also found significative correlations (p<0,05) between MIP and MEP to TG (r=0,637) and CG (r=0,846) groups. We conclude that there were differences in pulmonary function, exercise capacity and quality of life in patient with CKD that indicate some degree of functional impairment in this population. This functional impairment appears in haemodialysis patients and in post renal transplant patients.
