ABSTRACT

BACKGROUND: COVID-19 may lead to development of irreversible acute respiratory distress syndrome. Some patients sustain severe respiratory failure after infection subsides. They may require lung transplant as a last resort treatment. The aim of the study is to assess the effect and feasibility of lung transplant as a treatment for patients with severe irreversible respiratory failure due to COVID-19. METHODS: This retrospective study pertains to analysis of 119 patients in critical condition who were referred to Lung Transplant Ward (Zabrze, Poland). between July 2020 and June 2021 after developing respiratory failure requiring extracorporeal membrane oxygenation, invasive ventilation, or both, as well as a few patients on high-flow oxygen therapy. Inclusion criteria for referral were confirmed lack of viral disease and exhaustion of other therapeutic options. RESULTS: Of the referred patients, 21.84% were disqualified from such treatment owing to existing contraindications. Among the suitable patients, 75.8% died without transplant. Among all patients who were qualified for lung transplant, only 9 patients became double lung transplant recipients. Intraoperative mortality for this procedure was 33%. Four patients were discharged after the procedure and are currently self-reliant with full respiratory capacity. CONCLUSIONS: Patients with severe irreversible respiratory failure after COVID-19 present significantly high mortality without lung transplant. This procedure may present satisfactory results but must be performed in a timely fashion owing to critical condition and scarcity of lung donors, only aggravated around the time of peak infection waves.

ABSTRACT

BACKGROUND: When COVID-19 became a pandemic, it was difficult to predict how it would affect lung transplant recipients. The aim of this study was to assess the mortality, influence on graft function as well as attitude toward SARS-CoV-2 vaccination among lung transplant recipients from a single center. METHODS: We analyzed medical data pertaining to 124 recipients who received lung transplants between 2008-2021 from a single center and original questionnaire on the COVID-19 severity classification system and the patients' attitude toward SARS-CoV-2 vaccination. Graft function was assessed by spirometry and a 6-minute walk test (6MWT), at least at the first postCOVID-19 visit. RESULTS: Among 29 patients who were confirmed to have COVID-19, 6 people died during or directly after contracting this infectious disease. The significant decrease in spirometry and distance in a 6MWT has been rarely observed in COVID-19 survivors. After vaccination ( n=107 patients) , most patients reported mild symptoms with slight pain and discomfort at the injection site being the most common (51.4%). 67.7% of all studiedpatients did not have any fears regarding the vaccination. Others reported being significantly worried about its effects (19.4% agreed to receive a vaccination anyway and 12.9% refused to be vaccinated). CONCLUSIONS: COVID-19 may present significant mortality among lung transplant recipients. The short-term safety and outcomes of vaccinations among these patients seemed encouraging. We are aware of the small study group limitations and hope to research this issue further.

ABSTRACT

A 44-year-old male with no history of underlying diseases was referred to academic hospital due to ARDS with confirmed SARSCoV-2 infection after 7 days of mechanical ventilation. Veno-venous (VV) extracorporeal membrane oxygenation (ECMO) was initiated as no improvement was noted in prone position. Mechanical ventilation was continued with TV of 3-4 mL/kg. A gradual decline of static lung compliance was observed from baseline 35 mL/cm H20 to 8 mL/cm H2O. The chest CT scan revealed extensive ground-glass areas with a significant amount of traction bronchiectasis after 3 weeks since admission. When the patient was negative for SARS-CoV-2 during the 4th week of ECMO, the decision to perform an emergency lung transplantation (LTx) was made based on the ongoing degradation of lung function and irreversible damage to lung structure. The patient was transferred to the transplant center where he was extubated, awaiting the transplant on passive oxygen therapy and ECMO. Double lung transplantation was performed on the day 30th of ECMO. Currently, the patient is self-reliant. He does not need oxygen therapy and continues physiotherapy. ECMO may be life-saving in severe cases of COVID-19 ARDS but some of these patients may require LTx, especially when weaning proves impossible. VV ECMO as a bridging method is more difficult but ultimately more beneficial due to insufficient number of donors, and consequently long waiting time in Poland.
