简介:高免疫球蛋白E综合征(HIES)是一种罕见的免疫缺陷性疾病,表现为血清IgE水平升高、皮肤湿疹、反复皮肤感染和特征性的肌肉骨骼表现。作者报道2例在本院就诊的患者并回顾当前文献。患者1是一18个月大的非裔美国男孩,伴有复发性葡萄球菌冷脓肿、肺炎和菌血症。该患者皮肤严重湿疹化,最终并发疱疹性湿疹。在选用敏感抗生素环孢素A(5mg/kg)短期治疗全身性感染后,皮炎改善,随后改为长期口服甲氧苄啶一磺胺甲恶唑。患者2是一15岁高加索男孩,长期患有HIES。该患者从3岁开始即维持每周3次注射1干扰素和每月静脉注射免疫球蛋白,并预防性应用抗生素和小剂量氟康唑。
简介:目的探讨细胞因子IL-2和IL-10在早期梅毒发病中的作用。方法采用ABC-ELISA技术检测48例早期梅毒患者血清IL-2和IL-10水平。结果(1)早期梅毒患者血清IL-2水平明显高于正常对照组,IL-10水平明显低于正常对照组(P值均<0.001)。(2)一期梅毒患者血清IL-2和IL-10水平与二期梅毒无明显差异(P值均>0.05),不同RPR滴度间IL-2和IL-10水平无明显差异(P值均>0.05)。(3)治疗后IL-2水平明显下降(P<0.05),IL-10水平上升不明显(P>0.05)。(4)IL-2和IL-10之间呈正相关(r=0.5385,P<0.05)。结论早期梅毒出现Thl上调,在抵御TP感染过程中发挥积极作用。
简介:报告2例血管淋巴样增生伴嗜酸性粒细胞增多症。患者分别为28岁男性和26岁女性,病程分别为5年和1年,临床表现为主要分布在头面部的紫红色丘疹、结节。组织病理检查均有真皮层血管的增生,增生的血管内皮细胞呈特征性的上皮样,可内衬血管腔,突入血管腔内生长,血管内皮细胞胞浆丰富酸染,1例还可见特征性的空泡。血管周围大量淋巴细胞、嗜酸性粒细胞及组织细胞浸润。根据临床及皮肤组织病理,诊断为血管淋巴样增生伴嗜酸性粒细胞增多症。
简介:目的:探讨2μm激光治疗长期口服抗凝药物良性前列腺增生患者的安全性及有效性。方法:对28例长期服用抗凝药物良性前列腺增生患者行经尿道前列腺2μm激光“刀削面”式汽化切除术。结果:手术时间为30~70min,平均时间(45±13)min;术后持续膀胱冲洗1~3d;留置尿管2~6d,膀胱造瘘管于拔出尿管后次日拔出;术后住院时间4~7d。术后随访3~6个月,术前与术后6个月平均IPSS分别为:(22.7±4.5)分、(6.8±3.5)分;QOL分别为:(5.2±0.4)分、(2.2±1.2)分;Qmax分别为:(6.4±1.5)mL/s、(18.8±3.2)mL/s,上述三项指标与术前比较,均有明显改善(P<0.01)。结论:经过严格术前评估与恰当处理,2μm激光治疗长期口服抗凝药物良性前列腺增生患者安全有效。
简介:目的对重组人干扰素α-2B局部封闭联合液氮治疗跖疣的疗法与传统单纯液氮疗法的临床疗效及耐受性进行对比分析。方法将92例跖疣患者随机分成2组,治疗组47例,对照组45例,治疗组采用重组人干扰素α-2B局部封闭联合液氮治疗;对照组采用单纯液氮疗法治疗,4次为1个疗程。结果1个疗程后治疗组总有效率为93.61%,高于对照组的75.56%(P〈0.01),治疗组皮损痊愈所需的平均治疗次数(4.00±1.57)明显少于对照组平均治疗次数(7.00±1.26)差别有统计学意义(P〈0.05)。2组不良反应均为轻到中度,无患者因不良反应中途退出。结论重组人干扰素α-2B局部封闭联合液氮治疗跖疣疗效优于传统的单纯液氮疗法,值得临床使用。
