T45.AX4

Clinical Causes: Overdose of immune checkpoint inhibitors or immunostimulant medications Incorrect medication administration or dosing errors Unintended adverse reactions during immunotherapy treatment Misuse or abuse of immune-enhancing drugs Interactions with other medications leading to toxic effects Off-label use of immunostimulant drugs without proper medical supervision

Key Symptoms: Severe immune-related reactions such as inflammation affecting various organs Gastrointestinal symptoms including nausea, vomiting, diarrhea Respiratory issues like dyspnea or cough Skin reactions such as rash or swelling Fever and chills Muscle or joint pain Signs of organ dysfunction, including liver inflammation or kidney problems Altered mental status or confusion in severe cases General malaise and fatigue

Diagnosis Path: Diagnosis of poisoning due to immune checkpoint inhibitors or immunostimulant drugs involves a combination of patient history, clinical examination, and laboratory tests. Healthcare providers assess recent medication use, dosing history, and any adverse symptoms present. Blood tests may reveal organ dysfunction or inflammatory markers suggestive of immune-related adverse effects. In some cases, specific assays to detect drug levels or immune activity are utilized to confirm intoxication.

Treatment Protocols: Management of poisoning from these medications typically involves supportive care and addressing specific symptoms. Immediate actions may include discontinuing the offending drug, providing medications to counteract immune reactions, and maintaining organ function. In severe cases, hospitalization is necessary, and interventions such as corticosteroids or immunosuppressive therapies may be administered. The goal is to stabilize the patient, reduce immune-mediated tissue damage, and prevent further complications. Long-term follow-up is often required to monitor recovery and manage any ongoing immune-related issues.
