Strongyloides stercoralis

Record number: 
Adverse Occurrence type: 
MPHO Type: 
Time to detection: 
100 days
Alerting signals, symptoms, evidence of occurrence: 
CMV viremia and leukopenia, low-grade fevers, nausea, generalized malaise, episodes of cofee-ground emesis, gastric lavage positive for blood, acute respiratory distress requiring intubation. On hospital day 3: purpuric macules extending up the ventral penile shaft onto the suprapubic abdomen. The patient died on hospital day 28.
Demonstration of imputability or root cause: 
Endotracheal tube suction aspirates, bronchoalveolar lavage specimens, and nasogastric tube aspirates contained innumerable larvae of S.stercoralis. Given the patient’s lack of risk factors for Strongyloides exposure and negative IgG antibody titer, the donor serum was tested and was found to be S. stercoralis antibody positive.
Imputability grade: 
2 Probable
