“…Despite the similar characteristics of their patients to those of our study, no significant correlation was found, possibly owing to the smaller number of patients in their study than in ours. Another study also found no significant correlation between the 6-MWT and the SK score but in that study adolescents and adults with CF were evaluated,21 which might account for the lack of correlation, because age is one of the sources of the 6-MWT variations, as reported in other studies 14,22,23 . …”

INTRODUCTION:The Shwachman-Kulczycki score was the first scoring system used in cystic fibrosis to assess disease severity. Despite its subjectivity, it is still widely used.OBJECTIVE:To study correlations among forced expiratory volume in one second (FEV1), chest radiography, chest computed tomography, 6-minute walk test, and Shwachman-Kulczycki score in patients with cystic fibrosis and to test whether the Shwachman-Kulczycki score is still useful in monitoring the severity of the disease.METHODS:A cross-sectional prospective study was performed to analyze the correlations (Spearman). Patients with clinically stable cystic fibrosis, aged 3-21 years, were included.RESULTS:43 patients, 19F/24M, mean age 10.5 ± 4.7 years, with a median Shwachman-Kulczycki score of 70 were studied. The median Brasfield and Bhalla scores were 17 and 10, respectively. The mean Z score for the 6-minute walk test was −1.1 ± 1.106 and the mean FEV1 was 59 ± 26 (as percentage of predicted values). The following significant correlations versus the Shwachman-Kulczycki score were found: FEV1 (r = 0.76), 6-minute walk test (r = 0.71), chest radiography (r = 0.71) and chest computed tomography (r = −0.78). When patients were divided according to FEV1, a statistically significantly correlation with the Shwachman-Kulczycki score was found only in patients with FEV1 <70% (r = 0.67).CONCLUSIONS:The Shwachman-Kulczycki score remains an useful tool for monitoring the severity of cystic fibrosis, adequately reflecting the functional impairment and chest radiography and tomography changes, especially in patients with greater impairment of lung function. When assessing patients with mild lung disease its limitations should be considered and its usefulness in such patients should be evaluated in larger populations.

“…In a previous study carried out in our center, with the objective of evaluating the exercise capacity through the 6MWT in patients attended in the program of adults with CF, 41 patients were classified into three groups according to functional severity. As a result, there was no statistically significant difference between the groups for distance traveled, but 73.2% of the patients presented 6MWD below the lower threshold from normal to predicted . Martin et al followed a cohort of adult patients with CF for 12 years, with the objective of obtaining prognostic information through the 6MWT.…”

Objective: To evaluate the behavior of oxygen saturation curves throughout the six-minute walk test (6MWT) in patients with COPD. Methods: We included 85 patients, all of whom underwent spirometry and were classified as having moderate COPD (modCOPD, n = 30) or severe COPD (sevCOPD, n = 55). All of the patients performed a 6MWT, in a 27-m corridor with continuous SpO2 and HR monitoring by telemetry. We studied the SpO2 curves in order to determine the time to a 4% decrease in SpO2, the time to the minimum SpO2 (Tmin), and the post-6MWT time to return to the initial SpO2, the last designated recovery time (RT). For each of those curves, we calculated the slope. Results: The mean age in the modCOPD and sevCOPD groups was 66 ± 10 years and 62 ± 11 years, respectively. At baseline, SpO2 was > 94% in all of the patients; none received supplemental oxygen during the 6MWT; and none of the tests were interrupted. The six-minute walk distance did not differ significantly between the groups. The SpO2 values were lowest in the sevCOPD group. There was no difference between the groups regarding RT. In 71% and 63% of the sevCOPD and modCOPD group patients, respectively, a ≥ 4% decrease in SpO2 occurred within the first minute. We found that FEV1% correlated significantly with the ΔSpO2 (r = −0.398; p < 0.001), Tmin (r = −0.449; p < 0.001), and minimum SpO2 (r = 0.356; p < 0.005). Conclusions: In the sevCOPD group, in comparison with the modCOPD group, SpO2 was lower and the Tmin was greater, suggesting a worse prognosis in the former.

Capacidade submáxima de exercício em pacientes adolescentes e adultos com fibrose cística

Abstract: This study showed that most patients attending an adult CF program had reduced submaximal exercise capacity. The 6MWT can be valuable for identifying patients who might experience oxygen desaturation and physical impairment in daily activities.
