International guidelines recommend the use of integrase strand transfer inhibitor (INI)-based regimens as first-line antiretroviral (ARV) in both naive and experienced HIV-infected patients. We analyzed a multicenter cohort of HIV-infected patients, both naive and experienced, starting an ARV, including an INI. Chi-square test and nonparametric tests were used to assess differences in categorical and continuous variables, respectively. Kaplan–Meier survival analysis was performed to estimate the probability of maintaining the study drug and Cox-regression analysis to evaluate predictors of discontinuation. We enrolled 4,343 patients: 3,143 (72.4%) were males, with a median age of 49 years (interquartile range 41–55). Naive patients were 733 (16.9%), of whom 168 (22.9%) were AIDS presenters. Overall, 2,282 patients (52.5%) started dolutegravir (DTG), 1,426 (32.8%) raltegravir (RAL), and 635 (14.7%) elvitegravir (EVG). During 10,032 patient years of follow-up (PYFU), we observed 1,278 discontinuations (13 per 100 PYFU); 448 of them (35%) due to simplification and 355 (28%) to toxicities (98 for central nervous system toxicity). Reasons of discontinuation were different between INIs. Estimated probability of maintaining DTG at 3 and 4 years were 81.5% [95% confidence interval (CI): 80.5–82.5] and 76.3% (95% CI: 73.9–78.7), respectively; RAL 61.6% (95% CI: 60.2–63.0) and 54.1% (95% CI: 52.7–55.5); EVG 71.6% (95% CI: 69.2–74.0) and 68.3% (95% CI: 65.3–71.3) (p < .001). At a multivariable analysis, being on a RAL-based ARV [vs. DTG, adjusted hazard ratio (aHR) 2.9, 95% CI: 2.3–3.6, p < .001], a EVG-based ARV (vs. DTG, aHR 1.3 95% CI: 1.1–1.7, p = .049), and a peak HIV-RNA >500k cp/mL (aHR 1.3, 95% CI: 1.1–1.6, p = .006) predicted INI discontinuation. Our data confirm the good tolerability of INIs in clinical practice. Differences emerge between the three drugs in reasons for discontinuation.

整合酶抑制剂在临床实践中的总体耐受性:来自意大利多中心队列的结果

国际指南推荐使用基于整合酶链转移抑制剂 (INI) 的方案作为一线抗逆转录病毒 (ARV) 治疗初治和经验丰富的 HIV 感染患者。我们分析了一个多中心的 HIV 感染患者队列,包括初始和有经验的,开始 ARV,包括 INI。卡方检验和非参数检验分别用于评估分类变量和连续变量的差异。进行 Kaplan-Meier 生存分析以估计维持研究药物的可能性,并进行 Cox 回归分析以评估停药的预测因素。我们招募了 4,343 名患者:3,143 (72.4%) 名男性,中位年龄为 49 岁(四分位距为 41-55)。初治患者为 733 (16.9%),其中 168 (22.9%) 是艾滋病患者。总共有 2,282 名患者(52. 5%) 开始使用 dolutegravir (DTG)、1,426 (32.8%) raltegravir (RAL) 和 635 (14.7%) elvitegravir (EVG)。在 10,032 患者年的随访 (PYFU) 中,我们观察到 1,278 次停药(每 100 PYFU 中 13 次);其中 448 例 (35%) 是因为简化,355 例 (28%) 是因为毒性(98 例是中枢神经系统毒性)。INI 之间的终止原因不同。3 年和 4 年维持 DTG 的估计概率分别为 81.5% [95% 置信区间 (CI):80.5-82.5] 和 76.3% (95% CI:73.9-78.7);RAL 61.6%(95% CI:60.2-63.0)和 54.1%(95% CI:52.7-55.5);EVG 71.6% (95% CI: 69.2–74.0) 和 68.3% (95% CI: 65.3–71.3) ( 其中 448 例 (35%) 是因为简化,355 例 (28%) 是因为毒性(98 例是中枢神经系统毒性)。INI 之间的终止原因不同。3 年和 4 年维持 DTG 的估计概率分别为 81.5% [95% 置信区间 (CI):80.5-82.5] 和 76.3% (95% CI:73.9-78.7);RAL 61.6%(95% CI:60.2-63.0)和 54.1%(95% CI:52.7-55.5);EVG 71.6% (95% CI: 69.2–74.0) 和 68.3% (95% CI: 65.3–71.3) ( 其中 448 例 (35%) 是因为简化,355 例 (28%) 是因为毒性(98 例是中枢神经系统毒性)。INI 之间的终止原因不同。3 年和 4 年维持 DTG 的估计概率分别为 81.5% [95% 置信区间 (CI):80.5-82.5] 和 76.3% (95% CI:73.9-78.7);RAL 61.6%(95% CI:60.2-63.0)和 54.1%(95% CI:52.7-55.5);EVG 71.6% (95% CI: 69.2–74.0) 和 68.3% (95% CI: 65.3–71.3) (p  < .001)。在多变量分析中,基于 RAL 的 ARV [vs. DTG,调整后的风险比 (aHR) 2.9,95% CI:2.3–3.6,p  < .001],基于 EVG 的 ARV(对比 DTG,aHR 1.3 95% CI:1.1–1.7,p  = .049), HIV-RNA 峰值 >500k cp/mL(aHR 1.3,95% CI:1.1–1.6,p  = .006)预测 INI 停用。我们的数据证实了 INI 在临床实践中的良好耐受性。三种药物在停药原因方面存在差异。
