In children with Prader-Willi syndrome (PWS), growth hormone (GH) treatment has positive effects on bone mineral density (BMD). Two 1-year studies did not show a difference between GH or placebo on BMD in young adults with PWS. However, there are no studies investigating BMD during longer-term GH treatment in young adults with PWS.
Open-label, a prospective study in 43 young adults with PWS.
BMD of the total body (BMDTBSDS) and lumbar spine (BMADLSSDS) measured by DXA.
In the total group, estimated mean (95% CI) of BMDTB remained similar during 3 years of GH, being -0.76 (-1.11 to -0.41) SDS at start and -0.90 (-1.27 to -0.54) SDS after 3 years (P = 0.11), as did BMADLS, being -0.36 (-0.72 to 0.01) SDS and -0.46 (-0.77 to -0.16) SDS, respectively (P = 0.16). In men, there was a significant decrease in BMDTBSDS during 3 years of GH, while BMADLSSDS remained similar. In women, both BMDTBSDS and BMADLSSDS remained similar. BMDTBSDS was associated with female sex, lean body mass and age. The majority of patients received sex steroid replacement therapy (SSRT).
During 3 years of combined GH and SSRT treatment, BMD remained stable in the normal range in young adults with PWS. However, men showed a decline in BMDTBSDS, probably due to insufficient SSRT. We recommended to continue GH treatment in young adults with PWS and to start SSRT during adolescence unless puberty progresses normally.
在患有普拉德-威利综合征(PWS)的儿童中,生长激素(GH)治疗对骨密度(BMD)有积极影响。两项为期 1 年的研究并未显示 GH 或安慰剂对 PWS 年轻成人 BMD 的差异。然而,目前尚无研究调查 PWS 年轻成人接受长期 GH 治疗期间的 BMD。
43 名 PWS 年轻成人的开放标签、前瞻性研究。
通过 DXA 测量全身骨密度(BMDTBSDS)和腰椎骨密度(BMADLSSDS)。
在整个组中,GH 治疗 3 年后,估计平均(95%CI)BMDTB 保持相似,开始时为-0.76(-1.11 至-0.41)SDS,3 年后为-0.90(-1.27 至-0.54)SDS(P=0.11),BMADLS 也是如此,分别为-0.36(-0.72 至 0.01)SDS 和-0.46(-0.77 至-0.16)SDS(P=0.16)。在男性中,3 年内 GH 治疗后 BMDTBSDS 显著下降,而 BMADLSSDS 保持相似。在女性中,BMDTBSDS 和 BMADLSSDS 均保持相似。BMDTBSDS 与女性性别、瘦体重和年龄相关。大多数患者接受了性激素替代疗法(SSRT)。
在接受 GH 和 SSRT 联合治疗 3 年后,PWS 年轻成人的 BMD 保持在正常范围内稳定。然而,男性的 BMDTBSDS 下降,可能是由于 SSRT 不足。我们建议在 PWS 年轻成人中继续 GH 治疗,并在青春期开始时开始 SSRT,除非青春期正常进展。
