As such, HD patients are exposed to multiple stressors including cardiocirculatory,inflammatory, biologic, hypoxemic, and nutritional. This cascade of events can be termed thedialysis stress storm and sickness syndrome. Mitigating cardiovascular risk and morbidityassociated with conventional intermittent HD appears to be a priority for improving patientexperience and reducing disease burden. In this in-depth review, we summarize the hidden effectsof intermittent HD therapy, and call for action to improve delivered HD and develop treatmentschedules that are better tolerated and associated with fewer adverse effects.展开更多
