To evaluate the efficacy of a levonorgestrel 52-mg intrauterine system (LNG 52-mg IUS) in controlling abnormal uterine bleeding and improving quality of life in women with inherited bleeding disorders.
We assessed 20 participants laboratory diagnosed with inherited bleeding disorders, who presented with abnormal uterine bleeding and were registered in a Central Blood Center. The primary outcomes were menstrual bleeding volume and quality of life before and after LNG 52-mg IUS placement. We used the Pictorial Blood Loss Assessment Chart (PBAC) score for measuring menstrual bleeding and the Short Form-36 Health Survey to assess quality of life before and after LNG 52-mg IUS placement. We also conducted blood tests to evaluate the hematimetric level. Follow-up visits were conducted at 1, 3, 6, and 12 months after LNG 52-mg IUS placement. Statistical analyses were performed using the Friedman non-parametric test.
The use of LNG 52-mg IUS reduced uterine bleeding in women with inherited bleeding disorders. The median PBAC score was higher before LNG 52-mg IUS placement than at 3, 6, and 12 months after placement (p < 0.001). The amenorrhea rate was 70% after 12 months. There was an improvement in all eight parameters of quality of life (p < 0.001). The mean hemoglobin, ferritin, and serum iron levels were also higher at 12 months than before LNG 52-mg IUS placement.
LNG 52-mg IUS placement can effectively control abnormal uterine bleeding in women with inherited bleeding disorders and consequently improve their quality of life.
The results from our study suggest that women with inherited bleeding disorders who present with heavy menstrual bleeding can benefit from the use of a levonorgestrel-releasing intrauterine system similar to women without bleeding disorders.
评估左炔诺孕酮 52 毫克宫内节育系统(LNG 52-mg IUS)在控制遗传性出血性疾病女性异常子宫出血和提高生活质量方面的疗效。
我们评估了 20 名实验室诊断为遗传性出血性疾病、有异常子宫出血且在中心血库登记的参与者。主要结局是 LNG 52-mg IUS 放置前后的月经出血量和生活质量。我们使用图像出血评估图表(PBAC)评分来衡量月经出血,使用健康调查简表 36 项(SF-36)来评估 LNG 52-mg IUS 放置前后的生活质量。我们还进行了血液检查以评估血液学水平。在 LNG 52-mg IUS 放置后 1、3、6 和 12 个月进行随访。使用 Friedman 非参数检验进行统计分析。
LNG 52-mg IUS 减少了遗传性出血性疾病女性的子宫出血。放置 LNG 52-mg IUS 前的 PBAC 评分中位数高于放置后 3、6 和 12 个月(p<0.001)。放置后 12 个月的闭经率为 70%。生活质量的所有 8 个参数均有所改善(p<0.001)。放置后 12 个月的平均血红蛋白、铁蛋白和血清铁水平也高于放置前。
LNG 52-mg IUS 放置可有效控制遗传性出血性疾病女性的异常子宫出血,从而提高其生活质量。
我们的研究结果表明,有大量月经出血的遗传性出血性疾病女性可以从左炔诺孕酮释放宫内节育系统的使用中受益,与无出血性疾病的女性相似。
