High-flux dialysis involves the use of dialyzers with a larger pore size, allowing for the clearance of larger molecules, including middle molecules, that are not effectively removed by standard dialysis. A key disadvantage related to pyrogen reactions arises because high-flux dialyzers may allow for more rapid transport of substances, including potential allergens or endotoxins from the dialyzer material or the dialysis fluid itself into the bloodstream. This can lead to an increased risk of pyrogenic reactions, which are fever and other inflammatory responses caused by the presence of pyrogens in the body. The body's immune response can be triggered when these materials enter circulation, resulting in symptoms that can complicate the patient’s condition.

In contrast, while factors such as cost and clotting risks are important considerations, they are not specifically tied to the inherent nature of high-flux dialysis's increased permeability and its association with potential pyrogen reactions. Therefore, understanding the implications of pyrogen reactions is crucial in evaluating the safety and effectiveness of high-flux dialysis in patient care.
