Physical Compatibility of Reduced Glutathione for Injection With 44 Intravenous Drugs During Simulated Y-site Administration.

PURPOSE: Reduced glutathione (GSH) is extensively used in clinical therapeutics due to its antioxidative and cytoprotective properties. It is essential in the management of various chronic and acute conditions and serves as an adjunct therapy in oncology. Despite its widespread use, the physical compatibility of GSH with other intravenous drugs during Y-site administration has not been thoroughly investigated, posing risks such as reduced efficacy and adverse reactions. This study fills this critical gap by examining the physical compatibility of GSH with 44 commonly used intravenous drugs in simulated Y-site administration with 0.9% sodium chloride injection (NS) and 5% dextrose injection, aiming to enhance patient safety and clinical outcomes. METHODS: Simulated Y-site administration was conducted in vitro by mixing 24 mg/mL of GSH with equal volumes of 44 diluted intravenous drugs. Physical compatibility was assessed by observing visual changes, checking for the Tyndall effect, measuring turbidity, and monitoring pH levels at 0, 0.5, 1, 2, and 4 hours post-mixing. Physical compatibility was defined as the absence of color changes, gas evolution, particulate formation, and the Tyndall effect within 4 hours, with turbidity changes of less than 0.5 nephelometric turbidity units from baseline and pH variations of less than 10% from initial values. FINDINGS: GSH exhibited physical incompatibility with 11 of the 44 intravenous drugs evaluated, while it remained compatible with 33 drugs over 4 hours. IMPLICATIONS: This study reveals that while GSH is physically compatible with the majority of tested intravenous drugs, incompatibilities with 11 drugs under simulated Y-site conditions necessitate rigorous compatibility testing prior to co-administration in clinical settings. These findings emphasize the importance of such testing to prevent potential treatment failures and adverse effects. Further research is needed to explore chemical stability and therapeutic efficacy in clinical settings, ensuring the safe and effective use of GSH in medical treatments.

Lower-extremity deep vein thrombosis induced by oxaliplatin and capecitabine chemotherapy: A case report.

Oxaliplatin and capecitabine are instrumental in the adjunctive and palliative systemic management of colorectal cancer. The concurrent administration of these chemotherapeutic agents often results in adverse effects, such as nausea, vomiting, diarrhea, leukopenia, and hand-foot syndrome. However, reports of deep vein thrombosis (DVT) caused by oxaliplatin and capecitabine are scarce. In this case study, we report a rare occurrence of lower-extremity DVT triggered by synergistic oxaliplatin and capecitabine chemotherapy in a patient diagnosed with malignant colon cancer. During the initial cycle of chemotherapy, the patient demonstrated DVT within the intermuscular veins of the right calf and abnormalities in markers of coagulation function. Enlargement of the intermuscular venous thrombosis and an increase in coagulation markers were observed subsequent to the second chemotherapy cycle. From our experience of this case, we suggest that DVT is induced by oxaliplatin and capecitabine warrants vigilant attention. Risk assessment for DVT prior to chemotherapy, coupled with early detection and intervention, is crucial for DVT prevention. Furthermore, enhancing the awareness of health care professionals and patients about the potential of chemotherapy-induced DVT is of paramount importance. Consequently, this case carries significant clinical implications.

Anlotinib improved the reactive cutaneous capillary endothelial proliferation induced by camrelizumab: a case report.

Background: Programmed cell death protein-1 (PD-1) or its ligand PD-L1 monoclonal antibodies, opening a new era of tumor immunotherapy, and they have significantly improved the overall survival of many patients with advanced solid tumors. However, in addition to its effectiveness, we should also pay attention to its adverse effects. The instructions of the PD-1 inhibitor camrelizumab clearly indicate that reactive cutaneous capillary endothelial proliferation (RCCEP) is the most common adverse reaction; it is common for many immune checkpoint inhibitors (ICIs). Here we describe a case that anlotinib improved RCCEP induced by anti-PD-1 blockade camrelizumab with some focus on further management of this symptoms. Case Description: A 57-year-old man with squamous cell carcinoma of the upper lobe of the left lung, and with mediastinal lymphocyte and liver metastasis, received the fifth cycle of chemotherapy and immunotherapy with camrelizumab (200 mg, every 3 weeks). Four days after treatment with camrelizumab, the patient's face, head, neck, and chest skin had multiple scattered bright red round papules, which were diagnosed as RCCEP. The patient was treated with oral anlotinib (8 mg, once a day). After 5 days of treatment, the symptoms of RCCEP gradually eased, and the patient was discharged. Conclusions: In conclusion, we have reported a case of RCCEP induced by anti-PD-1 blockade camrelizumab. The patient was given oral anlotinib to relieve the symptoms of RCCEP. Suggesting that anlotinib could be a potential management to reduce the adverse reactions who are treated with camrelizumab. The risk for RCCEP should always be kept in mind during camrelizumab treatment.
