To evaluate the effect of combined use of stanazolol (ST) on the final adult height (FAH) in girls with idiopathic central precocious puberty (ICPP) and apparently decreased linear growth during gonadotropin-releasing hormone analog (GnRHa) therapy.
Sixty-three girls with ICPP and decreased velocity of growth of height (HV<4 cm/yr) during GnRHa therapy were divided into 3 groups based on the following types of interventions:group 1 (n = 20), GnRHa+ST [25-30 µg/(kg·d) every 3-month followed by 3-month discontinuation], group 2 (n = 21), GnRHa+recombinant human growth hormone [rhGH, 1-1.1 U/(kg·w)], group 3 (n = 22), GnRHa alone.HV, the advancement of bone age (BA) for chronological age (CA) (ΔBA/ΔCA) and FAH were compared among groups.
(1)Total duration of ST combination therapy was (12.22 ± 3.62) months, while total duration of combination of rhGH was (13.22 ± 6.80) months. (2)HV increased significantly in both group 1 [ (2.79 ± 0.60) cm/yr vs. (6.27 ± 1.98) cm/yr, P < 0.01] and in group 2 [(2.80 ± 0.50) cm/yr vs. (6.25 ± 1.98) cm/yr, P < 0.01] during combined therapy, but maintained at low levels in group 3 [(3.95 ± 1.10) cm/yr vs. (3.34 ± 0.95) cm/yr, P > 0.05].No significant differences of ΔBA/ΔCA were found among the three groups [0.25(0.11∼0.28), 0.22(0.15∼0.31),0.19(0.10∼0.32), P > 0.05]. (3)FAH was significantly higher than predicted adult height (PAH) before combined therapy, as well as higher than target height (THt) in both group 1 [(156.25 ± 2.90) cm vs. (150.78 ± 3.70) cm, P < 0.01, (156.25 ± 2.90) cm vs. (153.94 ± 2.62) cm, P < 0.01], and in group2 [ (157.33 ± 4.69) cm vs. (152.61 ± 3.92) cm, P < 0.01, (157.33 ± 4.69) cm vs. (154.39 ± 4.72) cm, P = 0.01].In group 3, FAH was similar to PAH [(153.88 ± 2.6) cm vs. (152.54 ± 5.86) cm, P > 0.05], and was less than THt [(153.88 ± 2.6) cm vs. (155.60 ± 4.52) cm, P = 0.02]. (4)In girls treated with ST, no hirsutism, clitorism or hoarse voice was recorded.No polycystic ovary syndrome was found by B-mode ultrasound.
Intermittent combined use of low dose ST therapy can increase HV and thus improve FAH in girls with ICPP and apparently decreased linear growth during GnRHa therapy.
评估司坦唑醇(ST)联合使用对特发性中枢性性早熟(ICPP)且在促性腺激素释放激素类似物(GnRHa)治疗期间线性生长明显减缓的女孩最终成年身高(FAH)的影响。
63例ICPP且在GnRHa治疗期间身高增长速度减慢(身高增长速度<4厘米/年)的女孩,根据以下干预类型分为3组:第1组(n = 20),GnRHa + ST[每3个月25 - 30μg/(kg·d),随后停药3个月],第2组(n = 21),GnRHa + 重组人生长激素[rhGH,1 - 1.1U/(kg·周)],第3组(n = 22),仅GnRHa。比较各组的身高增长速度(HV)、骨龄(BA)相对于实足年龄(CA)的进展(ΔBA/ΔCA)和FAH。
(1)ST联合治疗的总疗程为(12.22±3.62)个月,而rhGH联合治疗的总疗程为(13.22±6.80)个月。(2)联合治疗期间,第1组[(2.79±0.60)厘米/年对(6.27±1.98)厘米/年,P<0.01]和第2组[(2.80±0.50)厘米/年对(6.25±1.98)厘米/年,P<0.01]的HV均显著增加,但第3组维持在低水平[(3.95±1.10)厘米/年对(3.34±0.95)厘米/年,P>0.05]。三组间ΔBA/ΔCA无显著差异[0.25(0.11~0.28),0.22(0.15~0.31),0.19(0.10~0.32),P>0.05]。(3)联合治疗前,FAH显著高于预测成年身高(PAH),且在第1组[(156.25±2.90)厘米对(150.78±3.70)厘米,P<0.01,(156.25±2.90)厘米对(153.94±2.62)厘米,P<0.01]和第2组[(157.33±4.69)厘米对(152.61±3.92)厘米,P<0.01,(157.33±4.69)厘米对(154.39±4.72)厘米,P = 0.01]均高于靶身高(THt)。在第3组中,FAH与PAH相似[(153.88±2.6)厘米对(152.54±5.86)厘米,P>0.05],且低于THt[(153.88±2.6)厘米对(155.60±4.52)厘米,P = 0.02]。(4)接受ST治疗的女孩未记录到多毛症、阴蒂肥大或声音嘶哑。B超未发现多囊卵巢综合征。
低剂量ST间歇联合治疗可提高ICPP且在GnRHa治疗期间线性生长明显减缓女孩的HV,从而改善FAH。
