目的

探讨外科术后感染使用利奈唑胺致血小板减少症的高危因素,为临床用药安全提供依据。

方法

回顾性分析2021年1月至2021年12月使用利奈唑胺治疗外科术后感染的164例患者资料,通过单因素及多因素Logistic回归分析外科术后感染使用利奈唑胺致血小板减少症的高危因素。

结果

血小板减少发生率为13.4%(22/164)。22例患者的血小板计数从用药前的(184.0±54.1)×109/L降低到了用药后的(75.2±19.1)×109/L,用药前后血小板计数差异有统计学意义(P<0.05)。多因素分析显示:年龄≥65岁(OR=3.432,95%CI: 1.234-9.654)、用药时间>14d(OR=4.798,95%CI: 1.321-17.456)、抗菌药联用≥2种(OR=3.072,95%CI: 1.178-8.032)、肾小球滤过率(GFR)<30ml/min(OR=6.623,95%CI: 1.478-29.876)及Charlson共病指数(CCI)≥4(OR=5.998,95% CI: 1.654-21.789)为外科术后感染使用利奈唑胺致血小板减少症的高危因素(均P<0.05)。

结论

在临床实践中,对于存在高龄、长疗程用药、肾功能重度受损、高CCI及多药联用等特征的外科术后感染患者,使用利奈唑胺时需高度警惕,加强监测与干预,以防止血小板减少症发生风险,提升临床治疗安全性与有效性。

Objective

To explore the high-risk factors for linezolid-induced thrombocytopenia in patients with postoperative surgical infections, and to provide a basis for the safety of clinical medication.

Methods

A retrospective analysis was conducted on the data of 164 patients who received linezolid for postoperative surgical infections from January 2021 to December 2021. Univariate and multivariate Logistic regression analyses were used to identify the high-risk factors for linezolid-induced thrombocytopenia in these patients.

Results

The incidence of thrombocytopenia was 13.4% (22/164). In the 22 patients with thrombocytopenia, the platelet count decreased from (184.0±54.1)×109/L before medication to (75.2±19.1)×109/L after medication, with a statistically significant difference (P<0.05). Multivariate analysis showed that age ≥65 years (OR=3.432, 95%CI: 1.234-9.654), medication duration >14 days (OR=4.798, 95%CI: 1.321-17.456), combined use of ≥2 antimicrobial agents (OR=3.072, 95%CI: 1.178-8.032), glomerular filtration rate (GFR) <30ml/min (OR=6.623, 95%CI: 1.478-29.876), and Charlson Comorbidity Index (CCI) ≥4 (OR=5.998, 95%CI: 1.654-21.789) were high-risk factors for linezolid-induced thrombocytopenia in patients with postoperative surgical infections (all P<0.05).

Conclusion

In clinical practice, for patients with postoperative surgical infections who have characteristics such as advanced age, long-term medication, severe renal impairment, high CCI, and combined use of multiple drugs, high vigilance is required when using linezolid. Strengthened monitoring and intervention should be implemented to reduce the risk of thrombocytopenia and improve the safety and effectiveness of clinical treatment.
