[The correlation between blood concentrations of somatomedin C and the auxological characteristics in short-stature subjects].
In this study the authors evaluated the correlation between plasma somatomedin C (SmC) levels and auxological features in 129 short children, who have been subdivided into four groups: classical growth hormone (GH) deficiency (14 prepubertal subjects), normal responses to provocative stimuli tests, but diminished spontaneous GH secretion (40 prepubertal subjects), normal responses to provocative stimuli tests and normal spontaneous GH secretion (45 prepubertal subjects and 30 subjects at stage G2/B2-Ph2 of puberty). The following correlations with SmC are resulted, when all the subjects were considered: chronological age (r = 0.415, p = 0.0002), bone age (r = 0.557, p less than 0.0001), bone age/chronological age ratio (r = 0.493, p less than 0.0001), height SDs (r = 0.574, p less than 0.0001), height velocity SDs (r = 0.599, p less than 0.0001), but not weight variation % (r = -0.020, p: ns). In conclusion, the results of the study demonstrate a high correlation between SmC levels and auxological features, with the exception of weight.
