- Impact of Growth Hormone Therapy on Adult Height in Patients with PTPN11 Mutations Related to Noonan Syndrome(2019) MALAQUIAS, Alexsandra C.; NORONHA, Renata M.; SOUZA, Thaiana T. O.; HOMMA, Thais K.; FUNARI, Mariana F. A.; YAMAMOTO, Guilherme L.; SILVA, Fernanda Viana; MORAES, Michelle B.; HONJO, Rachel S.; KIM, Chong A.; NESI-FRANCA, Suzana; CARVALHO, Julienne A. R.; QUEDAS, Elisangela P. S.; BERTOLA, Debora R.; JORGE, Alexander A. L.Objectives: The aim of this study was to evaluate the response to recombinant human growth hormone (rhGH) treatment in patients with Noonan syndrome (NS). Materials and Methods: Forty-two patients (35 PTPN11+) were treated with rhGH, and 17 were followed-up until adult height. The outcomes were changes in growth velocity (GV) and height standard deviation scores (SDS) for normal (height-CDC SDS) and Noonan standards (height-NS SDS). Results: The pretreatment chronological age was 10.3 +/- 3.5 years. Height-CDC SDS and height-NS SDS were -3.1 +/- 0.7 and -0.5 +/- 0.6, respectively. PTPN11+ patients had a better growth response than PTPN11- patients. GV SDS increased from -1.2 +/- 1.8 to 3.1 +/- 2.8 after the first year of therapy in PTPN11+ patients, and from -1.9 +/- 2.6 to -0.1 +/- 2.6 in PTPN11- patients. The gain in height-CDC SDS during the first year was higher in PTPN11+ than PTPN11- (0.6 +/- 0.4 vs. 0.1 +/- 0.2, p = 0.008). Similarly, the gain was observed in height-NS SDS (0.6 +/- 0.3 vs. 0.2 +/- 0.2, respectively, p < 0.001). Among the patients that reached adult height (n = 17), AH-CDC SDS and AH-NS SDS were -2.1 +/- 0.7 and 0.7 +/- 0.8, respectively. The total increase in height SDS was 1.3 +/- 0.7 and 1.5 +/- 0.6 for normal and NS standards, respectively. Conclusions: This study supports the advantage of rhGH therapy on adult height in PTPN11+ patients. In comparison, PTPN11- patients showed a poor response to rhGH. However, this PTPN11- group was small, preventing an adequate comparison among different genotypes and no guarantee of response to therapy in genes besides PTPN11. (C) 2019 S. Karger AG, Basel
