Pregnancy and lactation-associated osteoporosis (PLO) is a rare condition characterized by fragility fractures occurring during late pregnancy or lactation, primarily affecting the spine and causing significant morbidity and back pain. PLO can lead to mobility impairment and work incapacity, with recovery taking up to several years. Due to the lack of clinical trials, treatment strategies remain poorly defined, historically focusing on calcium supplements, vitamin D, and weaning from breastfeeding. However, recent attention has turned to teriparatide (TPD) as an option due to its anabolic properties and potential suitability for women of childbearing age.
This review evaluates TPD's use in PLO treatment, using published systematic reviews and case studies. Over 300 cases with PLO were identified through PubMed, Google Scholar, and Cochrane searches until August 2023.
We identified 175 cases with PLO treated with TPD alone or followed by antiresorptive therapy. Most women (85.7%) were primiparas. The mean ± SD duration of TPD use was 15 ± 6 months. Among the study patients, 91.4% used TPD alone, while 8.6% (15/175) utilized sequential therapy. Approximately 93% of our cohort exhibited potential risk factors for PLO. Despite the increased risk of recurrent fractures in PLO, only 14.7% (20/175) of those treated with TPD sustained new fractures during a 9-month to 9 years' follow-up period. The mean ± SD percent increase in BMD at the LS was 21.14% ± 7.4%, and at the FN it was 12.1% ± 9.3%. The baseline Z-scores at the LS ranged from -3.3 (-3.7 to -2.7), while the baseline Z-scores at the FN ranged from -2.0 (-2.7 to -1.5).
This review emphasizes PLO severity, advocating for increased awareness and timely interventions. TPD emerges as a promising therapeutic option in certain cases.
妊娠和哺乳期相关骨质疏松症(PLO)是一种罕见病症,其特征是在妊娠晚期或哺乳期发生脆性骨折,主要影响脊柱,并导致显著的发病率和背痛。PLO 可导致活动能力受损和无法工作,恢复需要数年时间。由于缺乏临床试验,治疗策略仍未得到明确界定,历史上主要关注钙补充剂、维生素 D 和停止母乳喂养。然而,由于其合成代谢特性和对育龄妇女的潜在适用性,最近人们开始关注特立帕肽(TPD)作为一种选择。
本综述使用已发表的系统评价和病例研究评估了 TPD 在 PLO 治疗中的应用。通过 PubMed、Google Scholar 和 Cochrane 搜索,截至 2023 年 8 月,共确定了 300 多例 PLO 病例。
我们确定了 175 例单独使用 TPD 或随后使用抗吸收药物治疗的 PLO 病例。大多数女性(85.7%)为初产妇。TPD 使用的平均±标准差时间为 15±6 个月。在研究患者中,91.4%单独使用 TPD,而 8.6%(15/175)采用序贯治疗。我们的队列中约有 93%存在 PLO 的潜在危险因素。尽管 PLO 患者再次骨折的风险增加,但在 9 个月至 9 年的随访期间,仅 14.7%(20/175)接受 TPD 治疗的患者发生新骨折。LS 的 BMD 平均增加率±标准差为 21.14%±7.4%,FN 为 12.1%±9.3%。LS 的基线 Z 分数范围为-3.3(-3.7 至-2.7),FN 的基线 Z 分数范围为-2.0(-2.7 至-1.5)。
本综述强调了 PLO 的严重程度,倡导提高认识和及时干预。TPD 在某些情况下成为一种有前途的治疗选择。
