Are short boys with constitutional delay of growth and puberty candidates for rGH therapy according to FDA...

According to FDA-approved guidelines, boys whose height predictions fall to 160 cm or less are considered for treatment with recombinant growth hormone (rGH). The aim of this study was to analyze the value of different height prediction methods by accurately identifying those boys with constitutional delay of growth and puberty (CDGP) in whom final height (FH) prognosis was poor (

In 69 boys with CDGP diagnosed at a mean age of 14.9 +/-1.2 years, FH prediction was calculated by means of Bayley-Pinneau (BP), Roche-Wainer-Tissen (RWT), Tanner-Whitehouse II (TWII) and target height (TH) methods. At the age of 22.6 +/- 3.5 years their height was remeasured and the accuracy of height prediction was analyzed.

In 6 men (8.7%) measured FH was

Although some boys with CDGP may be considered the candidates for rGH treatment according to FDA recommendations, none of the available methods of prediction are sufficiently sensitive to reliably recruit 14- to 16-year-old boys whose final height will fall at or below 160 cm.
