However, in previous years, some transient metabolic complications have been described during this treatment, for which there are no long-term outcome data. Our study aimed to evaluate the efficacy of GnRHas and clarify if body mass index (BMI) at diagnosis of ICPP could influence long-term outcomes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This was an observational, retrospective study that recruited a cohort of girls with ICPP. Data for anthropometric measures, fasting lipid profile, and glucose metabolism were collected at baseline [when GnRHas treatment started (T1)], at the end of the treatment (T2), and near-final height (nFH) or final height (FH) (T3). Predicted adult height (PAH) was calculated at T1 following Bayley and Pinneau\u2019s method. Analysis was carried out using BMI standard deviation score (SDS) categories at T1 (group A, normal weight, vs. group B, overweight\/obese).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Fifty-seven girls with ICPP who were treated with GnRHas were enrolled in the study (group A vs. group B: 33 vs. 24 patients, aged 7.86 \u00b1 0.81 vs. 7.06 \u00b1 1.61 years, respectively; <jats:italic>p<\/jats:italic> &amp;lt; 0.05). In the study population, nFH\/FH was in line with the target height (TH) (<jats:italic>p<\/jats:italic> = 0.54), with a mean absolute height gain of 11.82 \u00b1 5.35 cm compared with PAH. Even if the length of therapy was shorter (group A vs. group B: 1.84 \u00b1 2.15 vs. 2.10 \u00b1 0.81 years, respectively; <jats:italic>p<\/jats:italic> &amp;lt; 0.05) and the age at menarche was younger (group A vs. group B: 10.56 \u00b1 1.01 vs. 11.44 \u00b1 0.85 years, respectively; <jats:italic>p<\/jats:italic> &amp;lt; 0.05) in group B than in group A, the nFH\/FH gain was still comparable between the two groups (<jats:italic>p<\/jats:italic> = 0.95). At nFH\/FH, BMI SDS was still greater in group B than in group A (<jats:italic>p<\/jats:italic> = 0.012), despite the fact that BMI SDS significantly increased in group A only (<jats:italic>p<\/jats:italic> &amp;lt; 0.05). Glucose metabolism got worst during GnRHa with a complete restoring after it, independently from pre-treatment BMI. The ratio of low-density to high-density lipoprotein cholesterol transiently deteriorated during treatment with GnRHas in group A only (<jats:italic>p<\/jats:italic> = 0.030).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Our results confirm the effectiveness of treatment with GnRHas on growth and do not support the concern that being overweight and obese can impair the long-term outcomes of GnRHas therapy. However, the observed transient impairment of metabolic parameters during treatment suggests that clinicians should encourage ICPP girls treated with GnRHas to have a healthy lifestyle, regardless of their pretreatment BMI.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fendo.2022.1006680","type":"journal-article","created":{"date-parts":[[2022,10,3]],"date-time":"2022-10-03T10:56:14Z","timestamp":1664794574000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":10,"title":["The
