HPV16 E7多肽冲击的树突状细胞治疗尖锐湿疣的临床初步观察

目的观察人乳头瘤病毒16型(HPV16)E749-57多肽冲击的树突状细胞(DCs)治疗复发性尖锐湿疣的疗效.方法 32例复发3次以上的尖锐湿疣患者,治疗组11例(HPV16 、HLA-A2 )给予HPV16E7多肽冲击的树突状细胞免疫治疗,对照组21例给予干扰素治疗.所有患者随访6个月,观察治疗前后皮损的病理变化、外周血T淋巴细胞亚群的变化及治疗效果.结果抗原肽冲击的树突状细胞治疗后,部分尖锐湿疣皮损变小或消退,局部空泡细胞减少,真皮内有中等密度淋巴细胞浸润.治疗前后外周血T淋巴细胞亚群未见明显变化.复发率由常规治疗的61.9%降至18.2%.结论 运用抗原肽冲击的树突状细胞对复发性尖锐湿疣进行治疗,可以改善病变局部的免疫状态,并能够显著降低复发率.

Clinical study of the therapy of condyloma acuminate by HPV16 E7 peptide-pulsed dendritic cells

Objective To investigate the therapeutic efficacy of HPV16 E7 peptide pulsed dendritic cells (DCs) in recurrent condyloma acuminate (CA). Methods A total of 32 cases of recurrent CA (more than 3 times) were divided into the treatment group and the control group. Patients (11 cases, HPV16 and HLA A2 ) in the treatment group received treatment with DCs, while the other 21 cases in the control group were treated with interferon. A follow up of 6 months was conducted in all patients. The pathological lesions, the peripheral T cell subpopulations of the patients, and the therapeutic efficacy before and after treatment were observed. Results The size of the lesions became smaller or disappeared in the treatment group. The infiltrated lymphocytes increased, but the koilocytotic cells decreased in the lesions. No significant change in the peripheral T cell subpopulations was found before and after therapy. The recurrence rates in the treatment group and the control group were 18.2% and 61.9%, respectively. Conclusion The therapy by E7 peptide pulsed dendritic cells can improve the local immune status in the skin and reduce the recurrence rate significantly in patients with recurrent CA.
