Therapeutic plasma exchange in the management of sepsis and multiple organ dysfunction syndrome: A report of three cases

Sepsis with multi organ dysfunction syndrome (MODS) is the most common cause of death in patients in noncoronary intensive care units. Currently, there are no specific treatments that reduce mortality in patients with sepsis and MODS. We report three patients who received therapeutic plasma exchange (TPE) for sepsis with MODS who completely recovered. The first patient, a 3‐year‐old male presented with Methicillin‐resistant Staphylococcus aureus‐associated respiratory, renal, coagulation, hepatic, and neurologic dysfunction. After 5 TPEs, the patient fully recovered. The second patient was a 36‐year‐old pregnant female who developed MODS at 22 weeks of gestation. She had developed respiratory, hepatic, renal, cardiovascular, neurologic, and coagulation dysfunction following pneumonia and concurrent urinary tract infection resulting in an intrauterine fetal demise. After 8 TPEs, the patient was discharged home with only mild residual hepatic dysfunction. The third patient, a 50‐year‐old female with a history of seizure disorder, was found unresponsive in over 100°F heat and diagnosed with Staphylococcus aureus‐associated MODS. Her respiratory, coagulation, neurologic, renal, and hepatic systems were affected. The patient underwent 6 TPEs after which she had marked improvement. In conclusion, TPE may be an effective adjunct therapy in MODS by possibly removing toxic mediators and replacing deficient factors using donor plasma. J. Clin.

Appropriateness,diagnostic value,and outcomes of repeat testing following index echocardiography

Aims

Emergency admission to hospital is associated with an economic burden and mortality. Echocardiography is often the first‐line cardiovascular imaging investigation. Repeat testing is common; however, there are sparse data on the prevalence, appropriateness, or outcome of repeat testing.

Methods

We performed an electronic database search for patients with emergency admissions to our institution in February 2015. An electronic patient record review of inpatient echocardiograms was undertaken. Indications for echocardiography were classified as appropriate, may be appropriate, or rarely appropriate. One‐year follow‐up for repeat testing and mortality was investigated.

Results

A total of 409 of 2306 (17.7%) unplanned/emergency admissions underwent inpatient echocardiography. Abnormalities were identified in 165/409 (40.3%) of these patients; 154 of 409 (37.7%) had a repeat echocardiogram within the next year. Rarely appropriate indications for echocardiography occurred in 51 (33%) of repeat vs 53 (16%) of index echocardiograms, P < .0001. Repeat testing was associated with a change in findings in 17/154 (11%) patients overall. All of whom had an abnormal index echocardiogram and had an appropriate indication. There was no difference in mean survival time between patients who underwent repeat and those who only underwent a single index echocardiogram (310 days vs 327 days), P = .34.

Conclusion

Inpatient echocardiography in emergency hospital admissions identifies clinically important pathology. Repeated testing is common within 1 year of hospital admission. New diagnostic findings occurred in 11% of patients and only in patients with appropriate studies and an abnormal index echocardiogram. Identification of methods to reduce repeat testing and implement appropriateness criteria is warranted.
