梅毒与HIV感染呈现特定人群聚集和共同增长的流行病学特点.近年来,二者的相互影响逐渐受到关注.梅毒可通过多种机制促进HIV的传播,与HIV的耐药变异及一过性的病毒载量增长可能存在相关性,但并未显著恶化HIV感染的预后.同时,HIV感染也可能改变梅毒的临床表现及血清试验结果,并导致梅毒的治疗失败和复发,然而,合并HIV感染的梅毒治疗方案仍存在争议.因此,有必要对梅毒与HIV共感染的免疫学机制开展深入研究,从而为进一步理解二者的致病机制及制定更加有效的防治措施奠定基础. 相似文献

梅毒不同的临床表现多取决于细胞免疫的强度和持续时间,巨噬细胞、CD4+T淋巴细胞、CD8+T淋巴细胞、自然杀伤细胞均在梅毒感染的细胞免疫中起重要作用.而与HIV合并感染更是增加了其免疫机制的复杂性和临床表现的多形性.在与HIV合并感染的二期梅毒中,Th1、Th17型细胞免疫增强,而Th2型细胞免疫的改变目前尚不确切.梅毒与HIV合并感染时两者的免疫机制、病程以及疗效均可能发生影响,因此,有必要进行梅毒患者的HIV筛查和HIV感染者的梅毒筛查,以便获得及时有效的治疗. 相似文献

Syphilis, a disease that in the past was associated with significant morbidity and lethality rates, has resurged in recent years principally as a consequence of changes in risk behavior. An epidemiological group that is commonly affected is the HIV-infected population. The characteristics of the disease and its progression may differ in these patients. The present report describes a case of an HIV-positive male patient, who developed florid secondary syphilis: in addition to syphilitic roseola, he also presented with bilateral panuveitis and involvement of the central nervous system. Investigation revealed the prozone phenomenon and histological examination of the skin lesions showed the presence of leukocytoclastic vasculitis. This finding is extremely rare and few cases have been documented. 相似文献

BACKGROUND: Syphilis was investigated in a group of HIV-infected women and their infants. GOAL: To assess syphilis morbidity among HIV-infected women and their infants. Among women with syphilis during pregnancy, the risks for delivering an infant with congenital syphilis were assessed. STUDY DESIGN: Through the Pediatric Spectrum of HIV Disease project, Texas infants born to HIV-infected women were identified. After the infants were matched with their mothers, it was determined which had been reported as syphilis cases. RESULTS: In this study 18% of the HIV-infected mothers were reported as syphilis cases, most during pregnancy. Half of these mothers delivered infants (n = 49) with congenital syphilis. Inadequate prenatal care was the only significant risk for delivering an infant with congenital syphilis. The congenital syphilis rate among Texas infants of HIV-infected mothers was 48.8 per 1,000 live births. CONCLUSION: The congenital syphilis rate among Texas infants born to HIV-infected mothers was almost 50 times that of the general population. 相似文献

Syphilis and HIV infection 总被引:1,自引:0,他引:1

The management of an HIV-infected patient with syphilis is an evolving and difficult area of clinical medicine. Many such patients initially present with dermatologic problems, and the practicing dermatologist must be alert to the variety of presentations syphilis may take in these patients. The role of biopsy with immunofluorescent or Warthin-Starry silver staining is often crucial in correctly diagnosing confusing cases. The treatment of early syphilis in HIV-infected patients may need to be more intensive than has previously been recommended, because the immunosuppression induced by HIV can accelerate the pace of the infection and increase the risk of progression to neurosyphilis. After treatment, careful and frequent follow-up is essential so that the often irreversible consequences of late syphilis can be avoided. 相似文献

Background. During the past 2 1/2 years we observed six patients who had a reactive serology for syphilis, of which four developed widespread noduloulcerative and two vesiculonecrotic lesions. The purpose was to report the occurrence of lues maligna, a rare form of secondary syphilis, in five patients infected with the human immunodeficiency virus (HIV) and in one patient with risk factors for infection. Methods. Tzanck preparations, viral cultures, and skin biopsies were performed to evaluate the etiology of the lesions. Results. Syphilis serology titers ranged from 1:32 to 1:128 and in one instance was as low as 1:8. Such titers can also be found in patients with the latent form of syphilis. Therefore, confirmation of the clinical diagnosis of lues maligna was dependent on skin biopsies that were compatible with secondary syphilis and negative viral studies that excluded varicella, disseminated varicella-zoster or herpes simplex. Lues maligna takes an aggressive course in HIV-infected patients since four of the patients required hospitalization and the two patients who refused to complete treatment, subsequently developed more severe skin and constitutional symptoms. Conclusions. HIV-infected patients are at risk for developing lues maligna. Despite its malignant presentation, lues maligna lesions respond rapidly to treatment with penicillin. Secondary syphilis should be added to the list of diseases known to be more aggressive in HIV-infected patients. 相似文献

OBJECTIVES: To assess the effect of human immunodeficiency virus (HIV)-1 and syphilis coinfection on HIV-ribonucleic acid (RNA) viral load, CD4 cell count, and the response in rapid plasmin reagin (RPR) to treatment of the syphilis infection. STUDY DESIGN: Cases of syphilis diagnosed during 1 year in HIV-infected patients in Copenhagen were included. HIV-RNA, CD4 cell counts, and RPR-serology were measured before, during, and after syphilis. RESULTS: Forty-one patients were included. CD4 cell count decreased significantly during infection in patients with primary and secondary stages of syphilis (mean 106 cells/mm, P = 0.03). Treatment of syphilis was associated with an increase in the CD4 cell count and a decrease in HIV-RNA in the overall group (mean 66 cells/mm and -0.261 RNA log10 copies/ml, P = 0.02 and 0.04). The serological response rates for 15 patients treated with penicillin and 25 treated with doxycycline were the same. CONCLUSION: Syphilis was associated with a decrease in CD4 cell counts and an increase in HIV-RNA levels that both improved after treatment of syphilis. 相似文献

Syphilis is a sexually transmitted disease with protean manifestations resulting from infection by Treponema pallidum. It is systemic early from the outset, the primary pathology being vasculitis. Acquired syphilis can be divided into primary, secondary, latent, and tertiary stages. The infection can also be transmitted vertically resulting in congenital syphilis, and occasionally by blood transfusion and non-sexual contact. Diagnosis is mainly by dark field microscopy in early syphilis and by serological tests. The management in the tropics depends on the diagnostic facilities available: in resource poor countries, primary syphilis is managed syndromically as for anogenital ulcer. The introduction of rapid "desktop" serological tests may simplify and promote widespread screening for syphilis. The mainstay of treatment is with long acting penicillin. Syphilis promotes the transmission of HIV and both infections can simulate and interact with each other. Treponemes may persist despite effective treatment and may have a role in reactivation in immunosuppressed patients. Partner notification, health education, and screening in high risk populations and pregnant women to prevent congenital syphilis are essential aspects in controlling the infection. 相似文献

目的:比较健康者、梅毒未治疗、梅毒治疗后转阴以及梅毒血清固定患者的血清IL-10和IL-12水平,并分析梅毒血清固定患者血清IL-12、IL-10水平之间的关系。方法:纳入健康者、梅毒未治疗、梅毒治疗后转阴以及梅毒血清固定患者各20例,检测并比较各组的血清IL-12、IL-10水平,并对梅毒血清固定患者血清IL-12、IL-10水平相关性进行分析。结果:对各组的IL-10水平进行检测和比较,各组间比较差异具有统计学意义(P0.05)。对各组的IL-12水平进行检测和比较,各组间比较差异不具有统计学意义(均P0.05)。对20例梅毒血清固定患者血清IL-12、IL-10水平之间的关系进行分析,可得二者之间无显著相关性(r=0.423,P0.05)。结论:梅毒血清固定患者体内会出现免疫失衡,细胞免疫受到抑制,进而导致梅毒螺旋体逃脱机体免疫监视发生残存,是导致血清固定的重要因素之一。 相似文献

OBJECTIVES: The objectives of this study were to determine predictive factors for neurosyphilis in HIV-infected patients with syphilis and optimize the use of lumbar puncture. STUDY DESIGN: The authors reviewed 112 cases of HIV-infected patients with syphilis who underwent a lumbar puncture. Diagnosis of neurosyphilis was based on a cerebrospinal fluid white blood cells count > or =20/microL, and/or a reactive cerebrospinal fluid-Venereal Disease Research Laboratory, and/or a positive intrathecal T. pallidum antibody (ITPA) index. RESULTS: Twenty-six of 112 had neurosyphilis. Neurologic manifestations and serum rapid plasma reagin (RPR) were associated with neurosyphilis (P = 0.036, P = 0.018, respectively). In multivariate analysis, log(2)RPR was still associated with neurosyphilis (P = 0.005). In patients without neurologic manifestations, the risk of neurosyphilis increases gradually with log(2)RPR. A serum RPR of 1/32 seems to be the best cutoff point to decide the performance or not of a lumbar puncture (sensitivity 100%, specificity 40%). CONCLUSION: In HIV-infected patients with syphilis, lumbar puncture could be restricted to those with neurologic manifestations or a serum RPR > or =1/32. 相似文献
