CASE PRESENTATION: A 40 year old previous healthy male presented in the emergency room with 4 days of dry
cough,
chest pain, myalgias and
fatigue. He progressed to ARF requiring high-flow-
nasal-cannula (flow: 60 L/minute, fraction of inspired
oxygen: 40%). Real-Time-Polymerase-Chain-Reaction (RT-PCR) assay confirmed
COVID-19 and chest X-ray showed interstitial infiltrates. Biochemistry suggested CRS: increased
C-reactive protein,
lactate dehydrogenase,
ferritin and
interleukin-6. Renal function was normal but
lactate levels were elevated. Electrocardiogram demonstrated non-specific changes and
troponin-I levels were slightly elevated. Echocardiography revealed left ventricular (LV) basal and midventricular akinesia with apex sparing (LV ejection fraction: 30%) and depressed cardiac output (2.8 L/min) consistent with a rare variant of stress-related
cardiomyopathy: RTCC. His ratio of partial arterial pressure of
oxygen to fractional inspired concentration of
oxygen was < 120. He was admitted to the intensive care unit (ICU) for
mechanical ventilation and vasopressors, plus
antivirals (
lopinavir/
ritonavir), and prophylactic anticoagulation. Infusion of
milrinone failed to improve his
cardiogenic shock (day-1). Thus, rescue TPE was performed using the Spectra Optia™
Apheresis System equipped with the Depuro D2000 Adsorption Cartridge (Terumo BCT Inc., USA) without protective
antibodies. Over 5 days he received daily TPE (each lasting 4 hours). His
lactate levels, oxygenation, and LV function normalized and he was weaned off vasopressors. His
inflammation markers improved, and he was extubated on day-7. RT-PCR was negative on day-17. He was discharged to
home isolation in good condition.
CONCLUSION:
