  秋冬换季,专家提醒警惕“免疫衰老”

  羊城晚报记者 林清清

  秋冬换季时,往往是中老年人的带状疱疹高发期。医生提醒,超过90%的成人体内都潜伏着带状疱疹病毒,每当免疫力低下,则可能激活病毒。对于中老年人,要警惕“免疫衰老”,强化免疫,预防疾病。

  九成人体内潜伏病毒 免疫低下可激活病毒

  免疫力是人体自带的防御机制,而带状疱疹的发病,往往提示此时身体的免疫力低下。

  俗称“生蛇”的带状疱疹,是中老年最常见的感染性疾病之一。

  广东省人民医院老年科主任张丽表示,“其实超过90%的成人,体内都潜伏有水痘-带状疱疹病毒,而大约1/3的人在一生中会患带状疱疹。当免疫力低下时,则可能激活病毒。同时,随着年龄增长,免疫功能逐渐下降,病毒则可能再次激活引发带状疱疹。年龄越大越容易患病,病情也更严重。”

  “我们从临床门诊也发现,近两年,带状疱疹就诊人数明显增加,相信这与人体免疫系统受到影响有关。”南方医科大学南方医院皮肤科主任曾抗对记者表示。

  警惕“免疫衰老” 50岁以上人群注意

  为何年龄越大越容易患病?对于“免疫衰老”,有没有年龄的警惕界限?在采访中,多位医生表示,大多数人在五六十岁会出现免疫力明显下降。

  “随着年龄的增长,身体免疫器官和组织功能开始下降,人体的免疫功能和人体机能也开始降低。”曾抗表示,“受‘免疫衰老’的影响,即便是身体健康人群,50岁以后患带状疱疹的风险也会明显增加。而慢性病患者罹患带状疱疹后,病情会更加严重且更容易诱发相关并发症。”

  老年人如何更高效强化免疫?国家卫生健康委办公厅发布的《老年失能预防核心信息》中,明确建议中老年人定期注射肺炎球菌疫苗和带状疱疹疫苗,流感流行季前在医生指导下接种流感疫苗。

  据记者了解,广州市多家社卫中心都会定期开展老年人疫苗接种专场,日常的疫苗接种门诊也会开设老年人优先通道,提高老年人接种的便利性。

  “老年人群往往有多种基础疾病共存。”广州市白云区金沙街社区卫生服务中心副主任刘霞提醒,“老年慢病人群由于免疫力低下,更易患感染性疾病,同时也会加大慢性病管理难度,因此更需要接种疫苗,主动预防。”

  刘霞提醒,尤其是老年慢病人群,应把自身健康状况充分与医生交流,由医生综合评估,给出疫苗接种方案。“免疫功能缺陷或免疫抑制疾病患者,不能接种减毒活疫苗。而对于重组蛋白疫苗,免疫功能低下或免疫受损不是接种禁忌。尤其是风湿免疫性疾病患者建议首选接种灭活疫苗和重组蛋白疫苗。”
