T45.AX1

Clinical Causes: Accidental overdose or incorrect administration of immune checkpoint inhibitors or immunostimulant drugs. Misinterpretation of dosage instructions or labeling errors. Lack of proper storage or handling leading to unintentional ingestion or exposure. Use of medications prescribed for others. Errors during medication preparation or delivery by healthcare providers.

Key Symptoms: Nausea and vomiting Fatigue and weakness Fever or chills Rashes or skin reactions Gastrointestinal discomfort Respiratory issues such as cough or shortness of breath Immune-related adverse effects like inflammation in organs (hepatitis, colitis, pneumonitis) Unusual bleeding or bruising Signs of allergic reactions, including swelling or difficulty breathing

Diagnosis Path: Diagnosis involves a thorough clinical assessment, including a detailed medical history and medication review. Healthcare providers may perform blood tests to identify signs of immune response or organ dysfunction, and look for evidence of poisoning. Confirmatory tests may include checking drug levels in the blood. Differential diagnosis considers infections or other causes of symptoms that mimic poisoning, and the healthcare team may also assess for immune-related adverse reactions that resemble poisoning effects.

Treatment Protocols: Management of poisoning from immune checkpoint inhibitors and immunostimulants focuses on supportive care, symptom relief, and preventing complications. Specific interventions may include: - Immediate discontinuation of the offending drug. - Administration of medications such as corticosteroids to reduce immune-related inflammation. - Supportive treatments like intravenous fluids, oxygen therapy, or medications to manage nausea or symptoms. - Monitoring and managing any organ-specific involvements, such as liver or lung issues. - In severe cases, hospitalization and intensive care may be necessary. - Consultation with specialists, such as immunologists or toxicologists, to tailor treatment plans. Long-term follow-up is often required to monitor for delayed or persistent effects after poisoning incidents.
