2、往往是因为早期梅毒未经彻底治疗，常为晚期（期）梅毒全身性损害的重要表现。The term“neurosyphilis”is frequently misunderstood to be synonymous with“tertiary syphilis”by health care personnel.Neurosyphilis is simply involvement of the central nervous system(CNS)with syphilis infection.The manifestations vary,though,and are usually divided

3、 into early neurosyphilis and late neurosyphilis.The late neurosyphilis manifestations usually manifest during the tertiary stage of syphilis and classically include dementia,general paresis,and tabes dorsalis,and are a result of extensive damage to the parynchema in the spinal cord or the cortical

4、regions of the brain.流行病学流行病学 梅毒在全世界流行，据WHO估计，全球每年约有1200万新发病例，主要集中在南亚、东南亚和次撒哈拉非洲。近年来梅毒在我国增长迅速，已成为报告病例数最多的性病。所报告的梅毒中，潜伏梅毒占多数，一、二期梅毒也较为常见，先天梅毒报告病例数也在增加。流行病学流行病学 10-50%of syphilis patients are HIV+15-20%of HIV+syphilis patients have symptomatic neurosyphilis。180,000-1.2 million cases of symptomatic neu

5、rosyphilis per year in HIV+individuals。The United States Centers for Disease Control and Prevention(CDC)reported that the incidence rate of syphilis in HIV-infected persons was 77-fold greater than that in the general population.Syphilis is a common co-morbidity with HIV,especially in the MSM(men wh

6、o have sex with men)community.MSM make up approximately 2/3 of cases of syphilis nationwide and HIV co-infection rates range from 34%in Houston to 51%in Chicago to 60%in Los Angeles and San Francisco.Flood et al.JID 1998;177(April)神经梅神经梅毒的疾病进程毒的疾病进程Christina M.Marra University of Washington，Seattle,

8、关闭不全，直至心力衰竭而死亡。初次性接触感染后的3天到3个月是一期梅一期梅毒毒，称为“硬下疳”，经过一段时间后会自愈；再经过4到10个星期发展为二二期梅毒期梅毒，症状多样，在躯干和四肢出现对称而不瘙痒的粉红色皮疹，随后演变成斑丘疹乃至溃疡，而口腔和咽喉黏膜上也会形成泛白的疣状病灶，接触传染性极强。Am Fam Physician.2012;86(5):433-440.临床症临床症状状(神神经梅经梅毒毒)临床常见的几种神经梅毒为：无症状性神经梅毒;脑膜神经梅毒;血管神经梅毒;脊髓痨;麻痹性痴呆;先天性神经梅毒。临床症状临床症状(神经梅毒神经梅毒)无症状性神经梅无症状性神经梅毒毒占15-40%，病

22、e-HIV era 神经梅毒的关键点：神经梅毒可被误诊为眼部的炎性疾病；神经梅毒最常累及的颅神经是面神经和位听神经；梅毒性耳炎可导致耳鸣，且是唯一的临床症状；在HIV阴性的病人中，神经梅毒患者的血清梅毒测定阳性；在HIV阴性的病人中，脑脊液血清性病研究实验室试验（VDRL)阳性提示神经梅毒，而梅毒螺旋体的PCR阳性螺旋体的脑脊液侵人。在HIV阳性的病人中，脑脊液血清性病研究实验室试验的滴度与疾病的状态不符，提示病人需要更为有效的治疗，相比HIV阴性患者，疾病的临床进展更快速。CDC-Neurosyphilis-Mandell:Principles and Practice of Infecti
