Abstract The aim of the longitudinal study was to assess skeletal status in 29 subjects (18 males and 11 females) with end-stage renal disease (ESRD) being on regular hemodialysis. Control group consisted of 494 healthy subjects (305 males and 189 females). Skeletal status was evaluated by quantitative ultrasound measurements at the hand phalanges using DBM Sonic 1200 (IGEA, Carpi, Italy), which measures amplitude-dependent speed of sound (Ad-SoS, in m/s), performed three times: at the baseline, six and 12 months later. A precision expressed in root mean square-CV% was 0.72% in males and 0.43% in females. The values of Ad-SoS, T-score and Z-score at the baseline were significantly lower than in controls ( p < 0.05). The mean values of Ad-SoS decreased over a period of observation; in the whole group from 1979 ± 106 m/s to 1928 ± 105 m/s, p < 0.0001, in males from 2003 ± 93 m/s to 1949 ± 111 m/s, p < 0.001 and in females from 1940 ± 121 m/s to 1894 ± 108 m/s, p < 0.05. Ad-SoS Z-scores dropped significantly over a period of the study in whole group (–1.14 ± 1.64 to –2.08 ± 2.26, p < 0.01), in males (–0.63 ± 1.44 to –1.74 ± 2.29, p < 0.0001) and in females nonsignificant decrease was observed. Using the least significant change (LSC) values for skeletal measurement, a decrease in Ad-SoS was noted in 15 subjects (52%). The values of PTH were over a normal limit. In the whole group main factors negatively influencing current Ad-SoS values were duration of dialysis, age and PTH. The skeletal status in subjects with ESRD on hemodialysis was seriously affected, and longitudinal measurements showed its aggravation over a time of the study. (E-mail: [email protected])
