Manufacturer Narrative

The plant investigation is in process. A supplemental mdr will be submitted upon completion of this activity. Clinical investigation: a temporal relationship exists between hd therapy utilizing the fresenius optiflux 160nre dialyzer and the serious adverse events of dialyzer reaction, characterized by hypertension and headache, which required a change in dialyzer type (baxter revaclear, not a fresenius product). The definitive etiology of the events is unknown; therefore, causality cannot be firmly established. However, given the patient¿s favorable response to the baxter revaclear dialyzer, a possible causal or contributory role cannot be excluded. Based on the information available, the optiflux 160nre dialyzer cannot be disassociated from the events. While uncommon, hypersensitivity reactions are known to occur with the use of optiflux dialyzers and/or other elements in the extracorporeal circuit. Additionally, hypersensitivity reactions have been known to occur days, months, even years after use with the same dialyzer model.

Event Description

A nurse practitioner contacted fresenius to report that an unknown patient on hemodialysis (hd) for renal replacement therapy (rrt) experienced a suspected dialyzer reaction to the optiflux 160nre dialyzer (date not provided). Follow-up with the patient¿s nurse practitioner (np) revealed the patient developed a headache and hypertension (timeline not provided) in conjunction with the utilization of the optiflux 160nre dialyzer. The patient reportedly transitioned to the baxter revaclear dialyzer and did not experience a return of symptoms. The patient did not require hospitalization and has recovered from the events. Subsequent attempts to obtain additional information (e. G. Patient demographics, outpatient home clinic, treatment records, medical records) have thus far proven unsuccessful.
