Abstract

Background: Coronavirus disease 2019 (COVID-19) remains a mystery in many respects. The importance of less common life-threatening diseases is still unclear. Therefore, in this study, it was attempted to determine the frequency of nontraumatic hemothorax, chylothorax, pleural, and pericardial effusion (PCE) in patients who underwent thoracic computed tomography during the pre-pandemic and pandemic period. Materials and Methods: This retrospective study included 147 patients over the age of 18 who were admitted to the emergency department between January 1st, 2019, and December 31st, 2020. The year 2019 was taken as the pre-pandemic period and the year 2020 was the pandemic period. Comorbidity, survival, and laboratory parameters of the patients were evaluated. Results: The mean age of the 147 patients included in the study was 66.41 ± 12.81 years, 54 (36.7%) were female, and the age range was 22–88 years. The mean plasma lactate dehydrogenase (LDH) level of the patients was 373.97 ± 115.77 U/L, plasma protein was 5.45 ± 1.00 gr/dL, fluid LDH was 229.37 ± 125.73 U/L, fluid/plasma LDH was 0.60 ± 0.23, fluid/plasma protein was 0.55 ± 0.29, and the amount of fluid discharged was 562.11 ± 243.01 mL. Bilateral lung involvement was present in 72 (49%) patients, and coagulation use was present in 59 (40.1%) patients. Pleural effusion (PE) was found in 43 (76.8%) of the hospitalized patients, hemothorax in 11 (19.6%) patients, and chylothorax in 4 (7.1%) patients. However, PCE was more common in the 16 (42.1%) patients admitted to the intensive care unit (ICU) (P < 0.001). While 38 (25.9%) of the patients were admitted to the ICU, mortality was observed in 30 (20.4%) patients. Conclusion: Although PE, nontraumatic hemothorax, chylothorax, and PCE are rare in COVID-19 patients, they can cause severe inflammation and poor prognosis.
