Aspects of Langerhans cells and TNF-α in the cutaneous immunity of anogenital warts

BackgroundAnogenital warts are the leading sexually transmitted infection in patients seeking care at specialized clinics. They may display a vast array of forms, according to the interaction of the virus with the host's immunity. Cellular immunity is the epithelium's main form of defense against the virus, involving an active participation of the Langerhans cells and pro-inflammatory cytokines such as TNF-α.ObjectiveTo assess the epithelial immune response of anogenital warts in males, according to the number of lesions presented.MethodsThis is a prospective, cross-sectional study carried out at the dermatology outpatient clinic in a tertiary hospital. We included male patients over 18 years of age without comorbidities who had anogenital condylomata and no previous treatments.In order to evaluate the local epithelial immunity, the lesions were quantified, then removed and employed in CD1a immunohistochemistry assays for assessing the morphometry and morphology of Langerhans cells; TNF-α; reaction was used for determining cytokine positivity in the epithelium.Results48 patients were included in the study. There was no statistically significant difference as to the number of Langerhans cells, in their morphology, or the presence of TNF-α. However, patients presenting with more Langerhans cells in the lesions had cells with a star-like and dendritic morphology, whereas in those with a lower cell count had cells with a rounded morphology and no dendrites (p < 0.001).Study limitationsSmall number of patients analyzed.ConclusionThere was no difference in epithelial immunity between patients having few or many anogenital condyloma lesions as measured by the morphology and morphometry of Langerhans cells and TNF-α; positivity. Such an assessment employing immunity markers differing from the usual ones is expected to yield useful results.     

尖锐湿疣患者局部皮损CD1a+郎格尔汉斯细胞表达及临床相关性研究

目的探讨尖锐湿疣(CA)组织中郎格尔汉斯细胞(LC)的变化与临床发病之间的相关性.方法将40例患者分为初发组及复发组,每组20例,并选择20例正常对照者.采用免疫组化法对患者的病变组织进行CD1a LC染色,应用现代图像分析技术对CD1a LC进行定量分析,并对CA患者的转归进行随访.结果CA皮损中CD1a LC树突状突起明显减少,大部分CD1a LC结构不完整.初发组CD1a LC为(13.45±9.42)个,复发组为(12.4±8.4)个,较正常组的(38.23±14.15)个均明显降低(P＜0.001).复发组CA皮损CD1a LC含量低于初发CA组(P＜0.05).结论CA的发病和复发与局部CD1a LC的数量有一定相关性.CD1a LC的形态特点和数量对判断CA的发病与复发有一定的参考价值.     

输尿管镜钬激光治疗尿道内尖锐湿疣(附5例报告)

尖锐湿疣患者IL—2和IFN—r水平观察

目的对人乳头瘤病毒(HPV)感染所致尖锐湿疣患者的IL-2和IFN-r水平进行观察,探讨HPV感染对机体细胞因子的影响。方法该研究调查了30例经临床诊断的尖锐湿疣患者,并经HPV6.II型PCR检测为阳性,其中随机抽取了10例进行组织病理学诊断,诊断结果均为尖锐湿疣。30例患者为CA患者组,选择30例正常健康者作为对照组,采用夹心酶联免疫吸附法(ELISA)试剂盒对30例CA患者和30例对照组受试者的血清中白介素-2(IL-2),r干扰素(IPN-r)的含量进行检测。结果CA患者与正常对照组对比较血清中IL-2(17.75±7.52pg/ml,P<0.01)和IFN-r(27.89±9.1pg/ml,P<0.05)的含量显著性下降。结论HPV感染导致尖锐湿疣患者血清中IL-2,IFN-r含量显著性下降,引起细胞免疫功能下降,因此,在临床上可以考虑用白介素-2和r干扰素治疗尖锐湿疣。     

Time‐lapse imaging points towards a non‐toxic,mainly immune‐driven mode of action of ingenol mebutate in the treatment of anogenital warts

Recently, it has been reported that ingenol mebutate (IM) is an effective treatment option for anogenital warts (AGW), inducing fast wart necrosis within 24 hours in vivo. With regard to its mode of action, IM is thought to act both as an inducer of direct cytotoxic effects and immunologic mechanisms. To distinguish whether the wart necrosis is mainly caused by cytotoxic effects, or whether immune mechanisms are leading, we used time‐lapse imaging to analyse IM‐treated warts ex vivo over 24 hours. Ex vivo IM‐treated warts, which have been detached from the immune system, did not show destructive necrosis, pointing towards a primarily immune‐driven mode of action of IM in the treatment of AGW.
