Oddly, I was going to ask about auto immune disease or an allergic sensitivity to the herceptin or herceptin part of kadcyla. My daughter has lupus. Twice she has gotten pericarditis when having a bad cold or even a super huge allergy attack. I understand your concern and fear. I am thinking of some kind of immune response here more than the more common effects of monoclonal antibodies. Is the fever you had a response to a true invader (virus or bacteria)? Or to a drug, food etc. My daughter gets a fever during a flare and her joints are the most affected for her. We know she will have alot of pain cuz there is an attack going on Either way you body over responded and got your pericardium involved. You might doubt a food sensitivity but they can come on quick especially when having treatment. For example, no more gluten, soy, corn or anchovies for my dear daughter. Didn't cure anything but .... Sound immuno to me but I m just trying to give you ideas to explore. Immuno response to true invader, herceptin/Kadcyla, food etc????
