Event Description
|
The customer reported that a lymphopheresis collection was done on a patient that was totally asymptomatic and with no records on previous infections and negative autologous pre-donation serologies.A sterility culture performed to lymphocyte collected product resulted positive for serratia marcescens.Sample taken in a class ii safety biologic cabinet from tubing segment detached from mother collection bag (no other samples taken during or after procedure), closed system maintained all the time.Upon positive culture, and approximately 24 hours after collection, cvc (central venous catheter) was removed and samples were taken from patient for culture, resulting all negative.Patient identifier and outcome are unknown at this time.Terumo bct is awaiting return of the disposable set for evaluation.

Manufacturer Narrative

This report is being filed to provide additional information in h.6 and h.10.Investigation: the customer provided a microbiology test report to aid in the investigation.The report confirmed that the bacteria identified was serratia marcescens.A review of the device history record (dhr) for this unit showed no irregularities during manufacturing that were relevant to this issue.The customer indicated that the sample was taken in a class ii biosafety cabinet from the tubing segment detached from the collection bag.There were no other samples taken during or after the procedure, and a closed system was maintained at all time.The bacterial testing was performed using bruker daltonik maldi biotyper.Per literature review, serratia marcescens is a gram-negative bacillus that produces a red pigment at room temperature.Serratia are considered to be ubiquitous in the environment and the organism is found in water, soil, plants, insects, animals, mammals including humans and food, particularly those rich in starch.There is no evidence to suggest a malfunction of the disposable kit or the spectra optia device caused or contributed to the bacterial contamination.Based on the available information, a specific root cause for the reported bacterial contamination could not be determined.The product was terminally sterilized to a sterility assurance level (sal) of =10-6 and had passed sterilization requirements.It is possible that the bacteria was introduced as a result of inadequate maintenance of the patient¿s central venous access or inadequate post-processing laboratory practices such as qc sampling or handling techniques.A disposable complaint history search was performed for this lot and found no other report for similar issues on this lot.Root cause: a root cause assessment was performed for the microbial contamination.Based on the available information a definitive root cause could not be determined but it is likely due to one or a combination of the possible causes listed below: * inadequate maintenance of the patient¿s central venous access.* inadequate post-processing laboratory practices such as qc sampling or handling techniques.
