摘要
目的 评价联合促性腺激素释放激素类似物(GnRHa)及司坦唑醇(ST)治疗对骨龄(BA)已较大的特发性中枢性性早熟(ICPP)女孩成年身高(FAH)改善的效果.方法 63例ICPP女孩在GnRHa治疗过程中出现生长速度(HV) <4 cm/年时,按所选继续治疗方案分为3组入组治疗:组1(20例):GnRHa+ ST[20 ~ 35 μg/(kg·d),每日1次顿服,每连续口服3个月后停3个月].组2(21例):GnRHa+重组人生长激素(rhGH).组3(22例):继续单独使用GnRHa.比较各组HV、BA/年龄增长比值(△BA/△CA)及FAH.结果 (1)组1 GnRHa+ ST治疗共(12.22 ±3.62)个月,组2GnRHa+ rhGH治疗共(13.22 ±6.80)个月.(2)组1和组2在入组治疗期间的HV显著高于入组治疗前[(6.27±1.98) cm/年和(2.79 ±0.60) cm/年,P<0.01,(6.25±1.98) cm/年和(2.80±0.50) cm/年,P<0.01],组3的HV与入组治疗前相比,差异无统计学意义[(3.34±0.95) cm/年和(3.95 ±1.10) cm/年,P>0.05].三组△BA/△CA分别为0.25(0.11 ~0.28)、0.22(0.15 ~0.31)、0.19(0.10~0.32),差异无统计学意义(P>0.05).(3)组1与组2的FAH分别为(156.25±2.90) cm和(157.33 ±4.69) cm,均高于入组治疗前预测成年身高[组1(150.78 ±3.70) cm,P<0.01,组2(152.61 ±3.92) cm,P<0.01]及遗传靶身高[组1(153.94 ±2.62) cm,P<0.01,组2(154.39±4.72) cm,P=0.01].组3的FAH与入组治疗前预测成年身高差异无统计学意义[(153.88±2.6) cm和(152.54±5.86) cm,P>0.05],且低于遗传靶身高[(155.60±4.52) cm,P=0.02].(4)组1无人出现多毛、嗓音粗、阴蒂肥大等表现.B超均未发现多囊卵巢表现.结论 ICPP女孩在接受GnRHa治疗过程中HV过度减速时,间歇、小剂量应用ST治疗可显著提高HV而不加速BA,最终可有效改善FAH,且未见女孩男性化等不良反应.
Objective To evaluate the effect of combined use of staaazolol (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. Meihod 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), GnBHa ST [ 25 - 30 Ixg/( 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. I-IV, the advancement of bone age (BA) for chronological age (CA) (ABA/ACA) and FAIl were compared among groups. Result (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) em/yr vs. (6. 25 ± 1.98 ) em/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 ABA/ACA 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) cmvs. (154. 39 ±4.72) cm, P=0.01].Ingroup3, 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. Conclusion 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.
