The Use of Therapeutic Plasma Exchange in the Treatment of a Pregnant Woman with COVID-19 Induced Acute Respiratory Distress Syndrome.

A 27-year-old woman at 17 weeks gestation was admitted to the intensive care unit (ICU) with a history of fever, dyspnea, and dry cough for 3 days. She was diagnosed with coronavirus disease 2019 (COVID-19) based on her nasopharyngeal swab polymerase chain reaction (PCR) that was positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). In the ICU, the patient developed acute respiratory distress syndrome (ARDS) and increased levels of inflammatory markers. She was then intubated for mechanical ventilation and had a treatment for critical COVID-19 illness during pregnancy. She also received three cycles on alternating days of therapeutic plasma exchange (TPE) since she was failing to respond to conventional medical treatment. During hospitalization, the patient's fetus was closely monitored by repetitive ultrasound. After 27 days of hospitalization and 10 days of mechanical ventilation weaning, the patient's respiratory condition improved and her inflammatory biomarkers normalized. She was discharged from the hospital with an apparently healthy 20th week fetus. This case report highlights the role of TPE for treatment of ARDS due to cytokine storm in pregnant women with severe COVID-19 infection. This case emphasizes that careful evaluation of clinical and biological progression of the patient's status is very important and when conventional therapies are failing, alternative therapies such as TPE should be considered.
