T45.A

Clinical Causes: Overuse or accidental overdose of immune checkpoint inhibitors or immunostimulant drugs Adverse reactions due to individual sensitivity or allergic response to the medication Incorrect administration or dosing errors Drug interactions with other medications altering the effectiveness or safety profile Poor drug absorption or metabolism leading to toxicity Use of medications beyond recommended duration or dosage

Key Symptoms: Fever and chills Skin rashes or allergic skin reactions Fatigue or weakness Nausea, vomiting, and diarrhea Difficulty breathing or shortness of breath Swelling of the face, lips, tongue, or throat Elevated liver enzymes or jaundice Muscle or joint pain Unusual bleeding or bruising Confusion or altered mental state Signs of infection due to immune system interference Symptoms indicating organ toxicity, such as chest pain or abdominal pain

Diagnosis Path: Diagnosis typically involves a comprehensive review of the patient's medical history, medication administration details, and the presentation of symptoms. Blood tests may be conducted to assess liver and kidney function, detect markers of inflammation or allergic reactions, and identify any signs of organ toxicity. Imaging studies or biopsies might be used if organ damage is suspected. Healthcare providers review medication dosing records to determine if medication errors contributed to the adverse effects.

Treatment Protocols: Discontinuation or adjustment of the offending medication Supportive care such as hydration, rest, and symptomatic relief Use of corticosteroids or immunosuppressants to manage severe allergic or immune-mediated reactions Administration of antihistamines or epinephrine in case of allergic reactions or anaphylaxis Monitoring of organ function through laboratory tests Treating specific complications, such as infections or organ toxicity, as they arise Long-term follow-up to monitor for delayed adverse effects
