目的了解2018—2022年邵阳市性病门诊男性就诊者性传播疾病的感染状况及艾滋病相关知识、行为变化情况。方法按照《全国艾滋病哨点监测实施方案》要求,对监测期内首次来哨点门诊诊治性病、年龄在16岁及以上的男性,采用连续采样方法,进行问卷调查并采集血样进行检测。结果2018—2022年共监测2000例性病门诊男性就诊者,其中年龄以20~49岁为主,占74.90%,平均年龄(38.4±12.8)岁;婚姻状况以在婚者为主,占67.1%。51人在最近一年中被诊断出患有性病,占2.55%,其中<20岁组(4.65%)和50~岁组(4.81%)患病率最高,不同年龄段中患性病的比例差异有统计学意义(χ^(2)=6.507,P<0.05)。HIV-1、HCV和现症梅毒检出率分别为0.05%、1.35%和1.05%。艾滋病知识知晓率逐年上升,分别为80.4%、86.3%、84.3%、94.8%、91.5%,差异有统计学意义(χ^(2)=59.050,P<0.001)。“蚊虫叮咬会传播艾滋病吗?”的知晓率最低为78.1%。艾滋病相关高危行为中,最近3个月与暗娼发生性行为占17.2%,与临时性伴发生性行为占16.6%。结论2018—2022年邵阳市性病门诊男性就诊者性传播疾病感染状况较为严重,艾滋病知识知晓率有待进一步提高,新冠疫情在一定程度上改变了人们的性行为方式,需多渠道、多维度的开展针对性艾滋病性病防治宣传,促进行为变化,减少感染风险。

肺炎支原体是临床上非典型性肺炎常见的致病菌,主要采用大环内酯类抗菌药物治疗。近年来,肺炎支原体对大环内酯类耐药性日趋严重,且全世界各地耐药率存在差异,目前认为其耐药机制主要与23S rRNA V区基因位点突变(2 063位和2 064位)相关... 详细信息

肺炎支原体是临床上非典型性肺炎常见的致病菌,主要采用大环内酯类抗菌药物治疗。近年来,肺炎支原体对大环内酯类耐药性日趋严重,且全世界各地耐药率存在差异,目前认为其耐药机制主要与23S rRNA V区基因位点突变(2 063位和2 064位)相关。根据肺炎支原体菌株P1基因序列的不同,应用聚合酶链式反应-限制片段长度多态性分析(PCR-RFLP)可分为Ⅰ型和Ⅱ型,其流行基因型随地区和时间的不同而不同。另外,为了解肺炎支原体耐药菌株之间是否存在克隆传播,可采用多位点可变数量串联重复序列分析(MLVA)方法分析肺炎支原体克隆型。加强肺炎支原体的耐药性及流行基因型的监测,有助于了解肺炎支原体的流行病学特点,为新型抗菌药物及疫苗的研发提供依据。

碳青霉烯类耐药的肺炎克雷伯菌(CRKP)是全球公共卫生问题,近年来在儿童人群中检出率不断上升,所引起的感染临床治疗失败率极高,具有较高的病死率。分离自儿童的CRKP所携带碳青霉烯酶基因呈现多样化,且多位于可传递质粒上,极易引起广泛传播和流行,临床工作人员应引起重视。加强对CRKP所致感染的控制亟需多学科合作,临床医生应根据微生物室提供的药敏试验结果选择有效抗菌药物,避免广谱抗菌药物的使用,同时采取相应的感控措施,可在一定程度上降低CRKP感染率。
