简介:目的:评价5-氨基酮戊酸光动力疗法(ALA-PDT)联合CO2激光治疗外生殖器尖锐湿疣对临床复发的影响。方法:86例外生殖器尖锐湿疣患者,采用开放随机对照方法分为治疗组和对照组。每组43例,两组患者均采用CO2激光治疗,治疗组在CO2激光治疗后加做ALA-PDT光动力治疗。治疗后第1、2、3、4、6、8、12、24周分别进行随访。随访中发现复发疣体采用CO2激光治疗。结果:82例完成全部观察疗程,其中治疗组42例,对照组40例。在随访第3周开始至随访结束,治疗组复发率明显低于对照组。第24周时,治疗组一次性治愈率80.95%,总复发率19.05%;对照组一次性治愈率50.00%,总复发率为50.00%,差异均具有统计学意义。结论:ALA-PDT能有效减少CO2激光治疗外生殖器尖锐湿疣的临床复发率,安全性高。
简介:目的:分析CO2激光祛除疣体联合胸腺五肽预防尖锐湿疣复发的临床效果。方法:选择在本院接受治疗的尖锐湿疣患者78例作为研究对象,随机分为观察组和对照组各39例,观察组接受CO2激光联合胸腺五肽治疗,对照组采用单纯CO2激光祛除疣体治疗。比较两组病例治疗后复发率及不良反应发生情况差异。结果:观察组1月、3月、6月复发率(分别为2.56%、7.69%、10.26%)低于对照组(分别为7.69%、17.95%、28.21%),差异有统计学意义(χ2值分别为4.39、4.59、4.31,P值均<0.05);不良反应发生率与对照组比较差异无统计学意义(χ2=2.01,P>0.05)。结论:CO2激光祛除疣体联合胸腺五肽可以有效降低尖锐湿疣患者治疗后的复发率,且安全性良好,具有积极的临床意义。
简介:目的:评价5-氨基酮戊酸光动力疗法联合CO_2激光治疗肛周尖锐湿疣的疗效。方法:治疗组30例应用5-氨基酮戊酸光动力疗法联合CO2激光治疗,对照组30例单用CO2激光治疗。每2周治疗1次,疗程6周。末次治疗后随访6个月,观察疗效及不良反应,并进行组间比较。结果:治疗组和对照组的治愈率分别为93.34%和66.67%,差异有统计学意义(χ2=6.67,P=0.010);不良反应主要是疼痛和溃疡,治疗组发生率为26.67%,对照组为60%,两组差异有统计学意义(χ2=6.79,P=0.009)。结论:应用5-氨基酮戊酸光动力疗法联合CO2激光治疗肛周尖锐湿疣治愈率高,复发率低,副作用小,值得临床推广。
简介:目的:评价CO2点阵激光联合丙酸氯倍他索乳膏治疗结节性痒疹的疗效及不良反应。方法:选取115例结节性痒疹患者,随机分成3组,治疗组接受CO2点阵激光联合丙酸氯倍他索乳膏治疗,对照1组采用CO2点阵激光单一疗法,对照2组采用丙酸氯倍他索乳膏单一疗法。于治疗第2、4、8周记录症状积分下降指数(SSRI)评分,比较三组有效率,并观察不良反应发生情况。结果:治疗2周后,治疗组与对照1组、对照2组有效率比较无明显差别;治疗4周后,有效率高于对照1组,但与对照2组无明显差别;治疗8周后,有效率高于两个对照组,差异有统计学意义(2值分别为12.25、11.00;P值均〈0.05)。3组患者均未发生严重的不良反应。结论:CO2点阵激光联合丙酸氯倍他索乳膏治疗结节性痒疹疗效显著,安全可靠,值得临床推广。
