ABSTRACT

Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) and its related disease (COVID-19) continue to represent a challenge for humans. To date, vaccination programs have represented an opportunity to navigate the pandemic. However, the advent of new genetic COVID-19 variants has increased more attention representing a worrying threat not only for not vaccinated but also for vaccinated people as virus infections have been shown also in the last ones. Herein, we report different clinical cases and radiological findings of COVID-19 pneumonia in six fully vaccinated patients. Two patients had a history of Rituximab therapy for follicular lymphoma and with persistent positivity for SARS-CoV-2 on nasopharyngeal/oropharyngeal (NP/OP) swabs and with moderate pneumonia on the chest computed tomography (CT). One patient who resulted to be positive to delta variant 8 days after the second vaccination dose, died shortly after. Two patients were hospitalized due to the worsening of fever and dyspnea in presence of mild pneumonia on CT. In one patient mild pneumonia was found on the chest-CT performed after a lipothymic episode associated with chest pain and positive NP/OP swab tested for SARS-CoV-2. These data suggested that in fully vaccinated people, caution should be preserved, and the use of masks and social distancing should be continued in all closed environments. However, further clinical trials should be done to better understand how various factors can influence vaccine immunogenicity as the presence of virus mutations, age factors, and the presence of an immunocompromised state.

ABSTRACT

PURPOSE: The aim of this study was to report the radiological features of chest CT scan of patients with coronavirus disease 2019 (COVID-19) living in a town in Southern Italy where a significant outbreak of the disease occurred. METHODS: We revised the CT scan of 62 patients (34 male, 28 female, mean age 71 +/- 14 years) with clinical and laboratory signs of COVID-19, as assessed by positive SARS-CoV-2 RT-PCR testing. All patients underwent chest CT at the time of admission to the hospital. A semi-quantitative scoring system was used to evaluate the extension of the disease. RESULTS: Out of the 62 patients the main radiological findings were reticular pattern (29%), ground-glass opacities (24%), crazy paving pattern (11%) and consolidation (35%). Most of the lesions were bilateral (97%), posterior (95%) and located near pleura (50%) or lung fissures (45%), mainly involving the lower right lobe (56%) and lower left lobe (23%). Pleural thickening was observed in 72.6% of patients and pleural effusion in 18%. Median value of the score was 7.0 and was significantly higher in male than female (8.5 vs 6.0, p=0.03) and in patients with pleural thickening compared to those without this finding (8.0 vs 5.0, p=0.03).

ABSTRACT

Severe acute respiratory syndrome-Coronavirus-2 (SARS-CoV-2) is a novel viral infection characterized by several symptoms range from mild to severe clinical conditions that could lead to death. We report two different radiological findings on computed tomography (CT) in two patients affected by SARS-CoV-2: a lung acute embolism (APE) in the first case and a radiological picture of acute respiratory distress syndrome (ARDS) in the second case. This is an important issue to be identified in order to provide more specific therapy earlier, including both antiviral and anti-inflammatory drugs associated with anti anticoagulant therapy.
