Description

非人类免疫性缺陷病毒感染患者PCP风险评估系统
技术领域
本发明涉及疾病风险评估领域,具体涉及非人类免疫性缺陷病毒感染患者PCP风险评估系统。
背景技术
卡氏肺孢子菌肺炎(PCP)是严重的机会性感染,与免疫功能抑制状态有关,常见于人类免疫性缺陷病毒(HIV)感染患者。因此PCP预防性化疗主要用于HIV/AIDS患者,首选甲氧苄啶-磺胺甲恶唑(TMP-SMZ)。然而,目前我国报道的PCP多发生在非HIV/AIDS,但该类患者预防性化疗应用缺乏成熟经验。
既往研究显示非HIV感染的PCP患者基础疾病以恶性肿瘤和器官移植接受免疫抑制治疗为主。近年来PCP预防用药的推广降低了这些患者罹患PCP的概率,但针对基础病以自身免疫性疾病的患者预防PCP的化疗缺乏研究。自身免疫性疾病本身并不意味着患PCP概率增加,糖皮质激素使用导致细胞免疫功能受抑是导致PCP更主要的原因。
临床上,针对HIV感染相关PCP的研究较多,如何预防和治疗的指南也不断更新。而非HIV相关的PCP虽然发病率逐年增加,但如何预防和治疗还没有统一的标准,是否对高危人群进行预防以及预防治疗的时间目前仍存在争议。
2011年美国胸科学会真菌感染指南推荐恶性肿瘤化疗患者、器官移植患者,或因炎性疾病接受免疫抑制治疗的患者,推荐在免疫抑制期间行预防治疗。非HIV感染的免疫抑制患者在泼尼松剂量大于20mg/d超过1个月时,尤其是患者有相关的T细胞缺陷或接受细胞毒药物或抗肿瘤坏死因子制剂时应该行PCP预防治疗。一些专家也建议检测这些患者的CD4+细胞计数,以CD4+细胞是否小于200/μl为界限来决定是否需要预防治疗。此外,有研究认为晚期COPD(GOLD IV期)患者带菌率远高于肺功能正常或轻度损害的者;重度营养不良同样为PCP的高危因素;CD4+细胞减少是PCP的独立危险因素。
本发明的创新之处是把患者基础疾病、年龄、体质状态(免疫功能、是否合并营养不良)、接受糖皮质激素和或免疫抑制剂治疗(剂量及疗程)以及其它呼吸道疾病结合起来,并根据现有的循证医学证据,建立一个全面、科学的评估体系,去评估非HIV患者发生PCP风险,决定是否进行预防治疗。从而有效地指导临床实践。
发明内容
本发明的目的在于提供非人类免疫性缺陷病毒感染患者卡氏肺孢子菌肺炎风险评估系统。
为实现上述目的,本发明提供如下技术方案:非人类免疫性缺陷病毒感染患者卡氏肺孢子菌肺炎风险评估系统包括非HIV感染患者COARIM-IAG发生PCP风险评估表以及涉及的评分公式,其中评分表中包含COARIM-IAG中每个字母是涉及的评分指标的英文首字母;其中COARIM中C(Cancer)恶性肿瘤化疗、O(Organtransplantation)器官移植术后、A(Autoimmune disease)自身免疫性疾病、R(respiratory disease)其它呼吸道系统疾病、I(Immunosuppressant)免疫抑制剂、M(malnutrition) 重度营养不良;IAG中I(Immunityfunction)免疫功能、A(Age)年龄、G(Glucocorticoid)糖皮质激素;
其中所述的恶性肿瘤包括实体肿瘤和血液系统肿瘤;器官移植包括心脏移植、肺移植、肾移植、肝移植、胰腺移植和其它器官移植;自身免疫性疾病包括皮肌炎、系统性红斑狼疮、干燥综合征、类风湿性关节炎;血管炎等风湿结缔组织病和其它自身免疫性疾病(肾病、过敏性紫癜、天胞疮等);其它呼吸系统疾病包括间质性肺病、支气管扩张、慢性支气管炎、慢性阻塞性肺疾病、肺结核、肺部混合感染。
所述的评分公式包含公式1和公式2:公式1:IAG评分= 0.01×[糖皮质激素剂量(mg/d)×时间(w)+年龄(y)] + 200/CD4+T(个/ul)
公式2:COARIM-IAG总评分 = COARIM评分 + IAG评分
作为优选,所述的公式1中糖皮质激素剂量是需换算成泼尼松剂量;
当COARIM-IAG总评分≥3分,提示高危,需行PCP预防。
与现有技术相比,本发明的有益效果如下:把患者基础疾病、年龄、体质状态(免疫功能、是否合并营养不良)、接受糖皮质激素和或免疫抑制剂治疗(剂量及疗程)以及其它呼吸道疾病结合起来,并根据现有的循证医学证据,建立一个全面、科学的评估体系,去评估非HIV患者发生PCP风险,决定是否进行预防治疗。从而有效地指导临床实践。
具体实施方式
下面将结合本发明实施例中对本发明的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
实施例
进行患者PCP风险评估时,把患者基础疾病、年龄、体质状态(免疫功能、是否合并 营养不良)、接受糖皮质激素和或免疫抑制剂治疗(剂量及疗程)以及其它呼吸道疾病根据 患者实际情况,根据风险评估表的评分标准进行评分,IAG评分需要根据公式1得出分值,最 终的风险评分需要根据公式2得出。其中评分表如下表所示;
字母代号 危险因素 评分
C(Cancer) 恶性肿瘤化疗 1
O(Organtransplantation) 器官移植术后 1
A(Autoimmune disease) 自身免疫性疾病 1
R (respiratory disease) 其它呼吸系统疾病 1
I(Immunosuppressant) 免疫抑制剂 1
M (malnutrition) 重度营养不良 1
I(Immunity function) 免疫功能 见公式1
A(Age) 年龄 见公式1
G(Glucocorticoid) 糖皮质激素 见公式1
本发明所需公式:
公式1:IAG评分= 0.01×[糖皮质激素剂量(mg/d)×时间(w)+年龄(y)] + 200/CD4+T(个/ul)
公式2:COARIM-IAG总评分 = COARIM评分 + IAG评分
注:
1、其中糖皮质激素剂量是需换算成泼尼松剂量;
2、COARIM-IAG总评分≥3分,提示高危,需行PCP预防。
尽管已经示出和描述了本发明的实施例,对于本领域的普通技术人员而言,可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型,本发明的范围由所附权利要求及其等同物限定。
