Afatinib-Related Severe Pneumonitis in a Patient with HIV under Anti-Retroviral Therapy: A Case Report

雞尾酒療法下人體免疫不全病毒感染者的Afatinib相關重症肺炎:病例報告

摘要


Afatinib, a second-generation epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI), improved progression-free survival and time-to-treatment failure as a first-line treatment in non-small cell lung cancer (NSCLC) patients. Use of combination antiretroviral therapy (cART) for human immunodeficiency virus (HIV) infection poses a potential risk of drug-drug interaction in HIV-infected patients simultaneously receiving EGFR-TKI treatment for NSCLC. EGFR-TKI-related pneumonitis is known as a serious drug toxicity. Previous research on EGFR-TKI-related pneumonitis mainly focused on gefitinib and erlotinib. We presented the first case of afatinib-related severe pneumonitis in a patient with NSCLC and HIV under cART. This study emphasizes the critical issue of drug-drug interaction between cART and afatinib. The patient's severe drug-related pneumonitis resolved after steroid pulse therapy.

並列摘要


Afatinib為二代EGFR-TKI,已被證實對有EGFR突變的非小細胞肺癌有療效。人類免疫不全病毒感染的患者是肺癌的高風險族群,而此類患者使用的抗病毒藥物雞尾酒療法會產生的藥物交互作用。使用EGFR-TKI治療肺癌,有1%的機率會產生嚴重的藥物引起的間質性肺炎。過去關於EGFR-TKI藥物引起的間質性肺炎病例報告都著眼於gefitinib或erlotinib,尚未有人分享過發生於人類免疫不全病毒感染的患者的間質性肺炎。因此,我們提出第一位同時使用afatinib及雞尾酒療法後發生間質性肺炎的人類免疫不全病毒感染的肺癌患者,在經過類固醇脈衝治療後恢復的案例。
