Abstract:

Objective To discuss the clinical efficacy of recombinant human growth hormone (rhGH) in the treatment of the pediatric patients with growth hormone deficiency (GHD) and idiopathic short stature (ISS), and to clarify its clinical application value in the pediatric patients with short stature of different etiologies. Methods The clinical data of 132 children with short stature who treated with rhGH from January 2018 to January 2023 were collected. They were divided into GHD group (n=70) and ISS group (n=62) based on different etiologies. The bone age, target height (TH), body mass index (BMI), height standard deviation score (HtSDS), changes in height standard deviation scores(ΔHtSDS) before treatment and 6 months after treatment, and growth velocity (GV) of the pediatric patients were calculated. Propensity score matching (PSM) and inverse probability of treatment weighting (IPTW) were used to balance the confounding factors between the pediatric patients in two groups and the efficacy and safety of the pediatric patients in two groups were evaluated. Results There were significant differences in whether children were full-term, bone age, bone age maturity, and TH of the pediatric patients between two groups (P<0.05). Compared with before treatment, the height and HtSDS of the pediatric patients in both GHD and ISS groups were significantly increased after treated for 6 months (P<0.05). Before matched by PSM, there were significant differences in full-term, bone age, bone age maturity, and TH of the pediatric patients between two groups (P<0.05). After matched by PSM, there were no significant differences in gender, region, term birth status, mode of delivery, feeding method, age, bone age, height, BMI, TH, and pretreatment HtSDS of the pediatric patients between two groups (P>0.05); the standardized mean difference (SMD) differences of covariates except for region were<0.2. After weighted by IPTW,there were no significant differences in gender, region, term birth status, mode of delivery, feeding method, age, bone age, height, BMI, TH, and pretreatment HtSDS of the pediatric patients between two groups (P>0.05); all SMD of covariates except for term birth status were<0.2. Before balancing covariates, after meatched by PSM matching, and after weighted by IPTW weighting compared with GHD group,the GV and ΔHtSDS of the pediatric patients in ISS group were slightly increased, but the difference was not significant (P>0.05). In terms of adverse reactions, 2 cases (2.68%) of fasting hyperglycemia and 7 cases (10.00%) of hypothyroidism occurred in GHD group; 3 cases (4.84%) of fasting hyperglycemia and 2 cases (3.23%) of hypothyroidism occurred in ISS group. Conclusion rhGH can promote the height increase in the patients with GHD and ISS, and there is no significant difference in the height-increasing efficacy between GHD and ISS children. The incidence of adverse reactions is relatively low during treatment, indicating good overall safety.
