RESUMO
BACKGROUND: Previous studies involving risk-benefit analysis of trastuzumab deruxtecan (DS-8201) have indicated the benefit of this treatment, although it may increase the risk of interstitial lung disease (ILD) and/or pneumonitis in certain patients. This study aimed to assess the safety of DS-8201. METHODS: A search was done for relevant articles in four electronic databases: PubMed, Embase, the Cochrane Library, and ClinicalTrials.gov. All reports published up until November 2, 2022, were included, and study types were restricted to clinical trials; the last search was then updated to January 10, 2023. We also assessed the quality of the literature with the Cochrane Handbook for Systematic Reviews of Interventions and the Methodological Index for Non-Randomized Studies tool, and then performed a meta-analysis with R version 4.2.1. RESULTS: A total of 1428 patients reported in 13 articles were included in this study. The analysis revealed that the most common all-grade treatment-emergent adverse events (TEAEs) were nausea and fatigue. The most common TEAE of grade 3 or above (grade ≥3) was neutropenia. The incidences of ILD and/or pneumonitis for all-grade and grade ≥3 TEAEs were 12.5% and 2.2%, respectively. CONCLUSIONS: This comprehensive summary of the incidence of TEAEs associated with DS-8201 in clinical trials provides an important guide for clinicians. The most common TEAEs were gastrointestinal reactions and fatigue; meanwhile, the most common grade ≥3 TEAE was hematological toxicity. ILD and/or pneumonitis were specific adverse drug reactions associated with DS-8201, of which physicians should be particularly aware for their higher morbidity and rates of grade ≥3 TEAEs.

PURPOSE: East Asian individuals have a lower risk of thromboembolic events while potentially carrying a higher risk of bleeding events compared with non-Asian individuals. The aim of the present analysis was to investigate the effectiveness and safety of the de-escalation of antiplatelet therapy compared with standard dual antiplatelet therapy (DAPT) in East Asian patients undergoing percutaneous coronary intervention (PCI). METHODS: Randomized controlled trials comparing de-escalation with DAPT in patients with acute coronary syndrome (ACS) were retrieved from electronic databases from their inception until March 2022. Outcomes included major adverse cardiovascular events (MACE), ischemic events, major bleeding, minor bleeding, and any bleeding. Subgroup analyses based on treatment strategy were conducted. Statistical analysis was performed by using Review Manager version 5.4. FINDINGS: Eight randomized controlled trials from 539 potentially relevant publications with a total of 15,744 East Asian patients were included. Pooled data from these studies found a significantly lower MACE (0.82; 95% CI, 0.69-0.98) and major bleeding event (0.62; 95% CI, 0.46-0.82) in de-escalation than standard-DAPT without heterogeneity. Subgroup analysis was divided into DAPT followed by P2Y12 inhibitor monotherapy and a reducing dose of P2Y12 inhibitors. DAPT followed by P2Y12 inhibitor monotherapy had a 48% lower incidence of major bleeding events than standard DAPT (0.52; 95% CI, 0.27-1.00); there was no significant difference in major bleeding (0.99; 95% CI, 0.55-1.76) between the reducing dose of P2Y12 inhibitors and standard DAPT. IMPLICATIONS: De-escalation is a promising and potentially optimal antiplatelet therapy for patients from East Asia with PCI. DAPT followed by P2Y12 inhibitor monotherapy might be a safer and equally effective approach compared with standard DAPT in East Asian patients with PCI. PROSPERO identifier: CRD42022319983.

Platelet factor 4 (PF4), also known as chemokine (C-X-C motif) ligand 4 (CXCL4), is a specific protein synthesized from platelet α particles. The combination of PF4 and heparin to form antigenic complexes is an important mechanism in the pathogenesis of heparin-induced thrombocytopenia (HIT), but vaccine-induced immune thrombotic thrombocytopenia (VITT) related to the COVID-19 vaccine makes PF4 a research hotspot again. Similar to HIT, vaccines, bacteria, and other non-heparin exposure, PF4 can interact with negatively charged polyanions to form immune complexes and participate in thrombosis. These anions include cell surface mucopolysaccharides, platelet polyphosphates, DNA from endothelial cells, or von Willebrand factor (VWF). Among them, PF4-VWF, as a new immune complex, may induce and promote the formation of immune-associated thrombosis and is expected to become a new target and therapeutic direction. For both HIT and VITT, there is no effective and targeted treatment except discontinuation of suspected drugs. The research and development of targeted drugs based on the mechanism of action have become an unmet clinical need. Here, this study systematically reviewed the characteristics and pathophysiological mechanisms of PF4 and VWF, elaborated the potential mechanism of action of PF4-VWF complex in immune-associated thrombosis, summarized the current status of new drug research and development for PF4 and VWF, and discussed the possibility of this complex as a potential biomarker for early immune-associated thrombosis events. Moreover, the key points of basic research and clinical evaluation are put forward in the study.

Endothelial cells (ECs) line the inner surface of blood vessels and play a substantial role in vascular biology. Endothelial dysfunction (ED) is strongly correlated with the initiation and progression of many vascular diseases. Regulated cell death, such as ferroptosis, is one of the multiple mechanisms that lead to ED. Ferroptosis is an iron-dependent programmed cell death associated with various vascular diseases, such as cardiovascular, cerebrovascular, and pulmonary vascular diseases. This review summarized ferroptosis of ECs in vascular diseases and discussed potential therapeutic strategies for treating ferroptosis of ECs. In addition to lipid peroxidation inhibitors and iron chelators, a growing body of evidence showed that clinical drugs, natural products, and intervention of noncoding RNAs may also inhibit ferroptosis of ECs.
