神经性厌食症(Anorexia Nervosa),一般简称为厌食症,是一种严峻进食妨碍,其特征是患者对身体外形及体重的自我感知歪曲而导致的自发的和继续的饮食摄入削减。依据美国精力疾病诊断与计算手册第五版(The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, DSM-V)可将厌食症分为限制型和暴食铲除型两个亚型。厌食症也常常共病郁闷症、焦虑症、逼迫症等精力疾病。成人厌食症的医治难度极大:尚无循证医学依据标明药物医治的有用性;据估计,约20%的患者对现医治手法无效。
课题组前期研讨成果显现双侧伏隔核(Nucleus Accumbens, NAcc)深部脑影响术(Deep Brain Stimulation,DBS)可作为难治性厌食症的有用外科神经调控医治手法,但仍需更大样本的随访行列研讨证明。
该前瞻性研讨旨在探求NAcc-DBS在难治性厌食症患者中的安全性和有用性,首要研讨结尾为术后两年随访节点手术相关并发症的发生率和身体质量指数(Body Mass Index, BMI)的改进程度;非必须研讨结尾为24项汉密尔顿郁闷量表(HAMD)、汉密尔顿焦虑量表(HAMA)、耶鲁-布朗逼迫量表(Y-BOCS)、社会功用缺点挑选量表(SDSS)和简易智力状况查看量表(MMSE)的改进程度。
本研讨入组29名难治性厌食症患者,1名患者因非医疗要素未完成两年随访,共28名患者归入数据剖析,其间限制型厌食症患者13名,暴食铲除型患者15名。术前基线BMI平均值13.01 (SD 1.86) kg/m2。
安全性方面,仅一名患者术后18月因排挤反响行手术取出影响器。未呈现颅内血肿、手术切断感染、电极移位、开裂等严峻手术并发症。
有用性方面,BMI在术后六月随访节点即得到明显改进,术后两年BMI平均值为17.73 (SD 3.54) kg/m2,明显优于术前基线水平。在心情共病方面,郁闷、焦虑、逼迫共病在术后两年随访节点也有明显改进。患者的社会功用评分明显优于术前基线水平。手术对患者的智力水平无明显影响。进一步的过后剖析则显现,NAcc-DBS作用在单纯限制型厌食症患者中的作用更为明显。
【ABSTRACT】
Background:Given that anorexia nervosa (AN) is a life-threatening mental disorder and has poor clinical outcomes, novel effective treatments are warranted, especially for severe and persistent cases.
Objective:To investigate the safety, feasibility, and clinical outcomes of using deep brain stimulation (DBS) of the nucleus accumbens (NAcc) in treatment-refractory AN patients.
Methods:A total of 28 women with refractory AN underwent NAcc-DBS and completed this 2-year follow-up study. The clinical outcomes, including body mass index (BMI) and mood, anxiety, and obsessive symptoms, were assessed using a series of psychiatric scales at 6 and 24 months post-operation.
Results:While no fatalities were reported during this study, 1 patient showed device rejection. The most common short-term side effect observed was varying degrees of pain at the incision sites (N = 22), which usually disappeared 3–4 days following the operation. No severe surgical adverse events were observed. Compared to pre-surgical levels, significant increases in BMI and improvement in psychiatric scale scores were noted during the 6-month follow-up and were maintained at the 2-year review. Finally, a post-hoc analysis revealed that the NAcc-DBS was less effective for weight restoration in patients with the binge-eating/purge subtype of AN than in those with the restricting subtype (R-AN).
Conclusion:Our long-term follow-up study suggests that NAcc-DBS is safe and effective for improving the BMI and psychiatric symptoms of patients with refractory AN. Although NAcc-DBS appears to be more suitable for patients with R-AN, strict inclusion criteria must be applied considering surgery-related complications.
【中文摘要】
布景:神经性厌食症是一种可危及生命的精力疾病,临床预后差。关于难治性神经性厌食症患者,急需更为有用的医治办法。
意图:探求伏隔核深部脑电影响术(NAcc-DBS)医治难治性神经性厌食的安全性、可行性和有用性。
办法:共28名女人难治性神经性厌食症患者接受了NAcc-DBS,并完成了为期两年的随访研讨。在术后六月和两年随访节点,一系列的精力病学量表被用于评价身体质量指数(BMI)、心情共病等临床预后目标。
成果:本研讨中未呈现逝世病例的报导,但一名患者呈现了对影响器的排异反响。最常见的手术相关短期不良事情为切断部位的痛苦(N =22),一般术后3-4天即可消失。本研讨未记录到严峻的手术相关不良事情。与术前基线比较,患者在术后六月随访节点的BMI明显添加,相关心情共病精力病学量表评分也得到明显改进,并保持至两年随访结尾。过后剖析显现,NAcc-DBS在暴食铲除型厌食症患者中的作用劣于限制型厌食症患者。
定论:本次长时间随访研讨标明,NAcc-DBS对医治难治性神经性厌食症的体重过低和心情共病是有用的。虽然NAcc-DBS在限制型厌食症患者中好像更为有用,但考虑到潜在的手术相关并发症,需求采纳严厉的手术入排规范。
