The aim of this retrospective study was to analyze the factors which affected the auxological response to GnRH agonist treatment and the final height (FH) outcome in 71 girls with idiopathic and truly precocious (onset before 8 years) central puberty (CTPP) who had been treated with the same therapy protocol (Decapeptyl Depot, 60 microg/kg i.m. every 28 days) for at least 2 years (since 7.0+/-1. 3 (S.D.) years of age) and followed until puberty was completed and FH was reached. During the entire treatment period we observed: (a) a decrease of height standard deviation scores (SDS) (from 1.5+/-1.7 to 0.9+/-1.3 SDS, P<0.01); (b) a striking deceleration of bone age (BA), revealed by the subnormal DeltaBA:Deltachronological age (CA) ratio (0.2+/-0.1); (c) an increase of predicted adult height (from 155.6+/-7.0 to 160.7+/-6.7 cm, P<0.0005). Treatment interruption was followed by an important catch-down growth, with an FH (158.4+/-5.8 cm) lower (P<0.025) than that predicted at the end of therapy. However, FH fell within the population norm and the target range in respectively 87.3 and 90% of the patients. The tallest FH was recorded in the patients who started therapy at less than 6 years of age and in those who discontinued treatment at a BA of 12.0--12.5 years. At stepwise regression analysis, FH in the whole study population was positively affected by the following independent factors: (a) height at the end of therapy (F=45.45, P<0.0001); (b) pretreatment height (F=13.91, P<0.0005); (c) treatment duration (F=8. 51, P<0.005); (d) target height (TH) (F=7.70, P<0.01). We conclude that: (i) most girls with idiopathic CTPP treated by GnRH agonists may achieve an adult height within the population norm and/or their target range; (ii) the height gain from therapy onset until FH attainment, however, is generally rather limited (on average 2.9 cm) and only few patients are able to reach their target percentile; (iii) the most favorable height prognosis with respect to TH is generally observed in the subjects with the tallest height at the end of treatment and the lowest BA2:CA2 ratio, due to the important deterioration of height prognosis which frequently follows therapy interruption; (iv) FH is also significantly conditioned by both TH and treatment duration; (v) in order to strengthen the weak therapeutic effect of GnRH agonists in CTPP this treatment should be started as early as possible and discontinued at a BA of 12.0--12.5 years.

AbstractAromatase inhibitors (AIs) have been used to recover height loss due to their capacity to delay growth plate closure. Long-term studies describing final heights are needed to determine the efficacy and safety profiles of these drugs for the treatment of impaired growth. This study aims to identify the therapeutic efficiency of AIs in improve growth and to describe potential adverse effects during treatment. Retrospective data analysis of 96 adolescents, among which 22 patients already attained near-final height, were followed at outpatient clinics of two referral centers. Patients were all in puberty and present idiopathic decrease in predicted adult height. Patients were treated with Anastrozole (ANZ: 1 mg/day) or Letrozole (LTZ: 2.5 mg/day) with/without recombinant human growth hormone (0.05 mg/kg/day) for 1.0 to 3.5 years (2.1±1.2 years). Height gain, body mass index, lipid, liver enzyme, gonadotropins and testosterone levels were described before and at the end of treatment. Predicted adult height (PAH) and NF height were compared with the TH. The height SDS (adjusted to bone age) significantly increased (p<0.05) in all groups [0.8±0.7 (ANZ), 0.7±0.7 (ANZ+GH), 0.3±0.5 (LTZ), and 1.2±0.8 (LTZ+GH)]; the latter group exhibited the highest increment of PAH and growth recovery to the TH (p<0.004). No significant side effects were observed. AI treatment, especially when used in association with GH was able to improve growth and the attainment of familial target height.

Abstract Background Aromatase excess syndrome (AEXS) is a rare autosomal dominant disorder caused by CYP19A1 overexpression. Clinical manifestations of AEXS include pre- or peri-pubertal gynecomastia, advanced bone age and compromised adult height. Case presentation Here we report an 8-year-old boy diagnosed with AEXS by chromosomal array that revealed a 1.1 Mb novel de novo duplication at 15q21.2, with a predicted final height of 157.4 cm. We prescribed letrozole and growth hormone (GH) to maximize his linear growth. Without further bone age advancement, his height increased from 137.7 cm to 144 cm after an 8-month treatment period. Conclusions We identified a novel duplication at 15q21.2 in AEXS, and found that aromatase inhibitor (AI) plus GH might provide a better growth-promoting approach for AEXS patients.

Abstract Objectives Longer-acting gonadotropin-releasing hormone analogs (GnRHa) have been widely used for central precocious puberty (CPP) treatment. However, the follow-up of patients after this treatment are still scarce. Our aim was to describe anthropometric, metabolic, and reproductive follow-up of CPP patients after treatment with leuprorelin acetate 3-month depot (11.25 mg). Methods Twenty-two female patients with idiopathic CPP were treated with leuprorelin acetate 3-month depot (11.25 mg). Their medical records were retrospectively evaluated regarding clinical, hormonal, and imaging aspects before, during, and after GnRHa treatment until adult height (AH). Results At the diagnosis of CPP, the mean chronological age (CA) was 8.2 ± 1.13 year, and mean bone age (BA) was 10.4 ± 1.4 year. Mean height SDS at the start and the end of GnRHa treatment was 1.6 ± 0.8 and 1.3 ± 0.9, respectively. The mean duration of GnRHa treatment was 2.8 ± 0.8 year. Mean predicted adult heights (PAH) at the start and the end of GnRH treatment was 153.2 ± 8.6 and 164.4 ± 7.3 cm, respectively (p<0.05). The mean AH was 163.2 ± 6.2 cm (mean SDS: 0.1 ± 1). All patients were within their target height (TH) range. There was a decrease in the percentage of overweight and obesity from the diagnosis until AH (39–19% p>0.05). At the AH, the insulin resistance and high LDL levels were identified in 3/17 patients (17.6%) and 2/21 patients (9.5%), respectively. The mean CA of menarche was 12.2 ± 0.5 years. At the AH, PCOS was diagnosed in one patient (4.8%). Conclusions Long-term anthropometric, metabolic, and reproductive follow-up of patients with CPP treated with longer-acting GnRHa revealed effectivity, safety, and favorable outcomes.

Abstract GnRH agonists improve final height in girls with “true” precocious puberty. To test if a comparable effect can be obtained in older girls, we performed a long-term controlled study in 30 caucasian girls whose puberty started between 8.4 and 10 yr (9.4 ± 0.1 yr), a variant of normal called “advanced” puberty. At entry into trial, these girls had clinical, biological, and sonographic manifestations of puberty and a bone age greater than 10.9 yr. They were randomized 2:1 to receive 3.75 mg triptorelin im every 4 weeks for 2 yr (n = 20, group I) or no treatment (n = 10, group II). Mean height at inclusion was 135.2 ± 4.3 cm (+0.6 sds) in group I, 136.1 ± 4.2 cm (+0.8 sds ) in group II, with target height 157.6 ± 4.3 cm (group I) and 157.8 ± 4.7 cm (group II), and predicted height (Bayley-Pinneau) 154.1 ± 3.9 cm and 155.2 ± 3.7 cm. Although GnRH agonists transiently delayed sexual maturation as well as bone age and growth rate, they had no clear-cut long-standing effect, and final height was comparable in treated (157.6 ± 4.0 cm) and untreated girls (156.1 ± 5.3 cm) (NS).

GnRH analogues (GnRHa) represent the treatment of choice in central precocious puberty (CPP), because arresting pubertal development and reducing either growth velocity (GV) or bone maturation (BA) should improve adult height. However, in some patients, GV decrease is so remarkable that it impairs predicted adult height (PAH); and therefore, the addition of GH is suggested. Out of twenty subjects with idiopathic CPP (treated with GnRHa depot-triptorelin, at a dose of 100 μg/kg im every 21 days, for at least 2–3 yr), whose GV fall below the 25th percentile for chronological age, 10 received, in addition to GnRHa, GH at a dose of 0.3 mg/kg·week sc, 6 days weekly, for 2–4 yr; and 10 matched for BA, chronological age, and duration of GnRHa treatment, who showed the same growth pattern but refused GH treatment, served to evaluate the efficacy of GH addition. No patient showed classical GH deficiency. Both groups discontinued treatment at a comparable BA (mean ± sem): 13.2 ± 0.2 in GnRHa plus GH vs. 13.0 ± 0.1 yr in the control group. At the conclusion of the study, all the patients had achieved adult height. Adult height was considered to be attained when the growth during the preceding year was less than 1 cm, with a BA of over 15 yr. Patients of the group treated with GH plus GnRHa showed an adult height significantly higher (P &lt; 0.001) than pretreatment PAH (160.6 ± 1.3 vs. 152.7 ± 1.7 cm). Target height (TH) was significantly exceeded. The group treated with GnRH alone reached an adult height not significantly higher than pretreatment PAH (157.1 ± 2.5 vs. 155.5 ± 1.9 cm). TH was just reached but not significantly exceeded. The gain in centimeters obtained, calculated between pretreatment PAH and final height, was 7.9 ± 1.1 cm in patients treated with GH combined with GnRHa; whereas in patients treated with GnRHa alone, the gain was just 1.6 ± 1.2 cm (P = 0.001). Furthermore, no side effects have been observed either on bone age progression or ovarian cyst appearance and the gynecological follow-up in the GH-treated patients (in comparison with those treated with GnRHa alone). In conclusion, a gain of 7.9 cm in adult height represents a significant improvement, which justifies the addition of GH for 2–3 yr during the conventional treatment with GnRHa, especially in patients with CPP, and a decrease in GV so marked as to impair PAH, not allowing it to reach even the third centile.

Background This study was conducted to find out whether boys with constitutional delay in growth and puberty (CDGP) could attain their target height and predicted adult height (PAH) in adulthood or not. Methods After measuring the height, weight, pubertal stage, parental height and bone age data of the patients at their first presentation were extracted from the files and their height and weight were measured at the end of the study, wrist X-Ray was performed in order to determine the bone age. PAH was calculated using Bayley–Pinneau method and target height was estimated by mid parental height. Final or near final heights of the patients were measured and compared with the target height and PAH. Results The mean age at presentation and the end of study was 15.2 ± 0.95, 20 ± 0.75 years respectively. Mean of bone age at the beginning of study was 12.97 ± 1 years and at the end of study were 17.6 ± 0.58 years. Mean of delayed bone age was 2.2 ± 0.82 years. Mean of the primary measured heights was 150.16 ± 7 cm (138–160 cm). Mean of final or near final heights was 165.7 ± 2.89 cm (161–170.5 cm). Final or near final heights in our subjects were smaller than either their PAH (165.7 ± 2.89 vs 170.7 ± 5.17) (P value <0.005) or target height (165.7 ± 2.89 vs 171.8 ± 4.65) (P value <0.0001). Conclusion Most patients with CDGP do not reach their target height or predicted adult height; they are usually shorter than their parents and general population. Such patients need to be followed up until they reach their final height and, in some cases, adjunctive medical treatment might be indicated.

We report 98 children who have reached final adult height in a long-term trial of LHRH agonist treatment. These children were 5.3± 2.1 yr old at the start of treatment and were treated with either deslorelin (4 μg/kg·d sc) or histrelin (4–10 μg/kg·d) for an average of 6.1 ± 2.5 yr. Final height averaged 159.8 ± 7.6 cm in the 80 girls, which was significantly greater than pretreatment predicted height (149.3 ± 9.6 cm) but still significantly less than midparental height (MPH) (163.7 ± 5.6). Final height averaged 171.1 ± 8.7 cm in the 18 boys, which was significantly greater than pretreatment predicted height (156.1 ± 14.2 cm) but still significantly less than MPH (178.3 ± 5.2 cm). However, the average adult height of the 54 children who had less than a 2-yr delay in the onset of treatment was not significantly different from their MPH, and 21 children exceeded MPH. Final height sd score correlated positively with duration of treatment (P &lt; 0.01), midparental height (P &lt; 0.001), predicted height at the start of treatment (P &lt; 0.001), and growth velocity during the last year of treatment (P &lt; 0.001) and correlated inversely with delay in the onset of treatment (P &lt; 0.001), age at the start of treatment (P &lt; 0.001), bone age at the start of treatment (P &lt; 0.001), bone age at the end of treatment (P &lt; 0.001), breast stage at the start of treatment (P = 0.02), and bone age minus chronological age at the start of treatment (P = 0.001). We conclude that LHRH agonist treatment improves the final height for children with rapidly progressing precocious puberty treated before the age of 8 yr for girls or 9 yr for boys. Less delay in the onset of treatment, longer duration of treatment, and lower chronological and bone age at the onset of treatment all lead to greater final height. All children with onset of pubertal symptoms before age 8 in girls and age 9 in boys should be evaluated for possible treatment. Treatment is appropriate in children with rapidly progressing puberty, accelerated bone maturation, and compromise of adult height prediction, regardless of bone age or chronological age at time of evaluation. However, once treatment is considered appropriate, it should be initiated quickly, because longer delays lead to shorter final height. In addition, the longer the treatment is continued, the greater is the final height outcome.

Abstract BackgroundThe growth potential of pubertal short stature boys is limited by the effect of estrogen on epiphyseal fusion. This study aims to identify the efficacy and safety of growth hormone (GH) combination with letrozole on final adult height (FAH) in pubertal short stature boys. MethodsThis is a retrospective study. Among pubertal short stature boys who treated with GH and letrozole were be followed up in our hospital, 20 cases reached FAH. ResultsBaseline chronological age were 12.12±1.14yr, bone age were 13.00±0.93yr. The treatment duration was 1.94±0.67yr. The height standard deviation score for bone age was increased from -1.46±0.51 to -0.12±0.57 (p<0.000). The predicted FAH before treatment, predicted FAH after treatment, FAH, and genetic target height were 161.02 ±4.12 cm, 172.11±4.20 cm, 172.67±2.72cm and 167.67±3.56 cm, respectively. There was significant differences between predicted FAH before treatment and after treatment (p<0.000), as well as predicted FAH before treatment and genetic target height (p<0.000).The predicted FAH after treatment was higher than that of genetic target height (p<0.001), as well as FAH and genetic target height (p<0.000). ConclusionsThe GH combination with letrozole can enhance the FAH in pubertal short stature boys. No significant side effects were observed.
