Manufacturer Narrative

The system was used for treatment.This case is reportable as a mdr due to the medical intervention of the intravenous (iv) iron infusions that were provided to the patient.Since this event is associated with the treatment, this mdr will be against the instrument.From the instrument perspective, there was no known instrument malfunction and no instrument issue was alleged by the customer.No service was requested by the customer for this adverse event.A device service history was not conducted for this case as this issue was not related to any specific instrument.Anemia is a known and labeled event that can occur if the patient's treatment frequency exceeds the labeling recommendation.In chapter 2-2 of the operator's manual under the adverse reactions section, it states " treatment frequency exceeding labeling recommendations may result in anemia." in chapter 2-8 of the operator's manual the normal treatment frequency is listed as "the patient should receive treatment on two successive days each month for six months.Patients who fail to show an "adequate response" to treatment after eight treatments may have their treatment schedules increased to two successive days every two weeks for the next three months.If no response, or less than an "adequate response" is achieved after 20 treatments, use clinical judgement to decide if ecp should be continued." the customer stated that the patient's anemia started after the patient underwent twice a week ecp treatment procedures for five weeks.Trends were reviewed for complaint category, anemia.No trends were detected for this complaint category.The assessment is based on information available at the time of the investigation.Complaints are monitored through tracking and trending.If a trend is detected, further investigation will be conducted.Adverse event term: anemia.(b)(4).

Event Description

The customer reported that an extracorporeal photopheresis (ecp) patient experienced anemia following a treatment procedure.The customer called to ask how many red blood cells were left in the kit at the end of an ecp treatment procedure.The customer was directed to technical bulletin number 8, which states 115ml of residual volume is left in the kit at the end of every ecp treatment procedure.The exact amount of red blood cells that are left in the kit at the end of an ecp treatment procedure is unknown.The customer asked if there was any way to reduce this residual volume within the kit.The customer also asked if there were any reports of patients developing iron deficiency anemia while on ecp treatment and if so how to prevent this anemia from occurring.The customer reported that he had a patient who may have developed iron deficiency anemia due to her ecp treatment procedures.The customer stated that the patient's anemia was first noted approximately five weeks into her ecp treatment procedure.The customer reported that the patient was undergoing ecp treatment procedures on a twice-weekly schedule when the patient's anemia was observed.The customer stated that all of the patient's ecp treatment procedures had been successfully completed with both blood and treated cells returned to the patient at the end of each treatment.The customer reported that the patient started her ecp treatment procedure on (b)(6) 2019.The customer stated that the patient's ecp treatment schedule was twice a week for 8 weeks, followed by twice a week every other week for 8 weeks, and finally twice a week, once a month.The customer reported that it was noted that the patient's hemoglobin level was decreasing and that this decrease coincided with the initiation of the patient's ecp treatment procedures.The customer stated that the patient's decline in hemoglobin prompted iron studies to be performed starting on (b)(6) 2019.The customer reported that the patient was administered intravenous (iv) iron infusions beginning on 09-may-2019 due to their anemia.The customer stated that the patient continues to receive her ecp treatment procedures with her last treatment being on (b)(6) 2019.The customer reported that the patient's anemia appears to have been resolved, with the patient's last hemoglobin reading being 12.1 g/dl on (b)(6) 2019.The customer stated that the patient had just finished the phase of her ecp treatment schedule where she received two ecp treatment procedures every other week for eight weeks as opposed to two treatments every week for eight weeks.The customer reported that he believed that this spacing out of the patient's ecp treatment procedures in conjunction with the patient's iv iron infusions might have likely contributed to the improvement of the patient's anemia.The customer stated that the patient's ecp treatment procedures could have caused or contributed to the patient's anemia since the patient's anemia coincided with the initiation of the patient's ecp treatment.The customer reported that many of their ecp patients experience a drop in their hemoglobin when starting their ecp treatment procedure, but most patients do not necessitate treatment.The customer stated that given that this patient was chronically ill; there is a risk of anemia however, this would not necessarily explain the onset of this patient's iron deficiency anemia.The customer reported that given the temporal association between the patient's anemia and their ecp treatment procedure in addition to the fact that this anemia has occurred in other ecp patients; this would argue in favor of the patient's ecp treatment procedure as being the primary etiology of the patient's iron deficiency anemia.No product was returned for investigation.
