Use of totally implantable venous-access ports (TIVAPs) is standard practice for patients with diseases such as solid-tumour cancers, haematological malignancies, and chronic digestive diseases. Use of TIVAPs allows long-term administration of venotoxic compounds, improves patients' quality of life, and reduces the risk of infection. Microbial contamination, formation of pathogenic biofilms, and infection, however, are associated with morbidity, mortality, and increased health-care costs. Local and systemic complications or infections related to specific pathogens might lead to device removal. Alternatively, conservative treatment with combined systemic antibiotics and antibiotic lock therapy might be useful. We discuss in-vitro and in-vivo basic and clinical research findings on the epidemiology, diagnosis, and prevention of TIVAP-related infections, the current challenges to management, promising strategies, and some treatments in development that are likely to improve outcomes of TIVAP-related infections, with a particular focus on antibiotic lock therapy.
使用完全植入式静脉输液港(TIVAP)是患有实体瘤癌症、血液恶性肿瘤和慢性消化系统疾病等疾病的患者的标准治疗方法。使用 TIVAP 可以长期给予静脉毒性化合物,提高患者的生活质量,并降低感染风险。然而,微生物污染、致病生物膜的形成以及感染与发病率、死亡率和增加的医疗保健成本有关。与特定病原体相关的局部和全身并发症或感染可能导致设备移除。或者,联合全身抗生素和抗生素锁定治疗的保守治疗可能是有用的。我们讨论了关于 TIVAP 相关感染的流行病学、诊断和预防的体外和体内基础和临床研究结果,目前管理方面的挑战,有前途的策略,以及一些正在开发的治疗方法,这些方法可能会改善 TIVAP 相关感染的结果,特别关注抗生素锁定治疗。
