Project description:Since the beginning of the COVID-19 pandemic, clinical, radiological, and histopathological studies have provided evidence that organizing pneumonia is a possible consequence of the SARS-CoV2 infection. This post-COVID-19 organizing pneumonia (PCOP) causes persisting dyspnea, impaired pulmonary function, and produces radiological abnormalities for at least 5 weeks after onset of symptoms. While most patients with PCOP recover within a year after acute COVID-19, 5-25% of cases need specialized treatment. However, despite substantial resources allocated worldwide to finding a solution to this problem, there are no approved treatments for PCOP. Oral corticosteroids produce a therapeutic response in a majority of such PCOP patients, but their application is limited by the anticipated high-relapse frequency and the risk of severe adverse effects. Herein, we conduct a systematic comparison of the epidemiology, pathogenesis, and clinical presentation of the organizing pneumonias caused by COVID-19 as well as other viral infections. We also use the clinical efficacy of corticosteroids in other postinfection OPs (PIOPs) to predict the therapeutic response in the treatment of PCOP. Finally, we discuss the potential application of a candidate anti-inflammatory and antifibrotic therapy for the treatment of PCOP based on the analysis of the latest clinical trials data.

Project description:BackgroundAs a pandemic, a most-common pattern resembled organizing pneumonia (OP) has been identified by CT findings in novel coronavirus disease (COVID-19). We aimed to delineate the evolution of CT findings and outcome in OP of COVID-19.Materials and methods106 COVID-19 patients with OP based on CT findings were retrospectively included and categorized into non-severe (mild/common) and severe (severe/critical) groups. CT features including lobar distribution, presence of ground glass opacities (GGO), consolidation, linear opacities and total severity CT score were evaluated at three time intervals from symptom-onset to CT scan (day 0-7, day 8-14, day > 14). Discharge or adverse outcome (admission to ICU or death), and pulmonary sequelae (complete absorption or lesion residuals) on CT after discharge were analyzed based on the CT features at different time interval.Results79 (74.5%) patients were non-severe and 103 (97.2%) were discharged at median day 25 (range, day 8-50) after symptom-onset. Of 67 patients with revisit CT at 2-4 weeks after discharge, 20 (29.9%) had complete absorption of lesions at median day 38 (range, day 30-53) after symptom-onset. Significant differences between complete absorption and residuals groups were found in percentages of consolidation (1.5% vs. 13.8%, P = 0.010), number of involved lobe > 3 (40.0% vs. 72.5%, P = 0.030), CT score > 4 (20.0% vs. 65.0%, P = 0.010) at day 8-14.ConclusionMost OP cases had good prognosis. Approximately one-third of cases had complete absorption of lesions during 1-2 months after symptom-onset while those with increased frequency of consolidation, number of involved lobe > 3, and CT score > 4 at week 2 after symptom-onset may indicate lesion residuals on CT.

Project description:We performed scRNA sequencing to understand the cellular heterogeneity and immune response landscape behind COVID-19 pathophysiology. We combine this with Ab-Seq, oligo-attached antibody based quantification of cell surface proteins to better understand the cell type and state of the cells. Samples were multiplexed using BD single-cell multiplexing kit (Human) in order to measure these data simultaneously

Project description:COVID-19 is a highly infectious respiratory disease caused by severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2). Starting from Wuhan (China) where it was firstly reported, it rapidly spread to the rest of the world, causing a pandemic with more than 300,000 deaths to date. We report an extremely severe case of coronavirus pneumonia in an over 80-year-old patient with hypertension, coronary heart disease, chronic heart failure, and chronic obstructive pulmonary disease. Despite a clearly poor anamnestic and clinical prognostic forecast, she was successfully discharged thanks to a careful evaluation of the case and of the complications that have arisen. Although a higher vulnerability of geriatric patients has been observed, the literature on elderly COVID-19 patients has remained very scarce, especially in those over 80. The article aims to explore factors that may allow the successful outcome and provides important elements to better understand this disease.

Project description:In patients recovering from coronavirus disease 2019 (COVID-19) pneumonia, respiratory symptoms and radiographic pneumonic infiltrate occasionally persist for many weeks even after viral clearance; thereby, making it difficult to decide on an appropriate treatment. Here, we describe a 46-year-old woman with COVID-19 pneumonia who had persistent radiographic pneumonic infiltration and respiratory symptoms for almost 4 weeks after illness onset, despite viral clearance, and was subsequently diagnosed with secondary organizing pneumonia (SOP) using video-assisted thoracoscopic (VATS) wedge lung biopsy. Intravenous methylprednisolone was administered at an initial dose of 50 mg/day (1 mg/kg) for 7 days and was tapered to a dose of prednisolone 30 mg/day following improvement in the patient's respiratory symptoms and chest radiographic findings. The patient was discharged from the hospital 14 days after the initiation of corticosteroid treatment. The dose of prednisolone was tapered monthly to 20, 15, 10, and 5 mg/day, respectively, at the outpatient clinic for a total duration of 6 months; nearly resolved pneumonic infiltrations were observed in a follow-up computed tomography scan approximately 2 months after she was admitted. To the best of our knowledge, this is the first case report of a COVID-19 associated SOP that was pathologically confirmed through VATS wedge lung biopsy in Korea. SOP should be considered in the differential diagnosis of patients with COVID-19 pneumonia with persistent respiratory symptoms and radiographic pneumonic infiltrations during the recovery phase to avoid the redundant use of antimicrobial or antiviral agents. Furthermore, histological confirmation is essential for the definitive diagnosis of SOP to avoid unnecessarily prolonged corticosteroid treatment.

Project description:COVID-19 can lead to pulmonary complications, including organizing pneumonia. Steroids are essential in treating post-COVID-19 organizing pneumonia. However, research on the clinical benefits of initiating steroid treatment early for this condition is limited. To investigate the steroid initiation time in its association with treatment duration and corticosteroid dose for treating post-COVID-19 organizing pneumonia, we analyzed the data of 91 patients with post-COVID-19 organizing pneumonia at Chonnam National University Hospital between October 2020 and December 2022. Patients were categorized into early and late groups based on time from COVID-19 diagnosis to steroid initiation time for organizing pneumonia. The mean time interval between COVID-19 infection and steroid initiation time for treating organizing pneumonia, was 18.4±8.6 days. Within the early treatment group (treatment initiated <18.4 days after COVID-19), which included 55 patients, the mean duration of steroid treatment was 43.1±18.3days. In contrast, the late treatment group (initiated ≥18.4 days after COVID-19), which consisted of 36 patients, had a longer mean duration of steroid treatment 59.1±22.6 days) (p<0.01). Regarding corticosteroid dosing, the early treatment group had an average dosage of 0.5±0.3 mg/kg/day, in contrast to the late group, which averaged 0.8±0.3 mg/kg/day (p<0.01). Regression analysis showed steroid initiation time significantly influenced treatment duration (β=0.80 , p<0.01) and dosage (β=0.03, p<0.01). The clinical benefits of early steroid treatment for post-COVID-19 organizing pneumonia may lie in its association with reduced steroid treatment duration and dosage.

Project description:ObjectiveBreast MRI is used to screen high-risk patients and determine extent of disease in breast cancer (BC) patients. The goal of this study was to determine the pathologic correlates of breast MRI abnormalities biopsied under MRI guidance.MethodsWe retrospectively identified 101 MRI-guided core needle biopsies (CNB) of the breast from 79 women over a 4-year period. MRI-detected lesions biopsied with ultrasound or stereotactic guidance were excluded. MRI studies and pathology were reviewed by breast radiologists and pathologists.ResultsOf the 79 patients, 72 (91%) had a history of prior (n = 13) or concurrent (n = 59) BC. There were 101 MRI abnormalities: 60 (59%) with non-mass enhancement (NME) and 41 (41%) with mass enhancement. Pathology was benign in 83/101 (82%), including in the majority of NME lesions (43/60, 72%). The most common benign findings were: fibrocystic changes (FCC) (49%), sclerosing lesions (13%), and fibroadenoma (FA) (9%). There were 18 (18%) malignant diagnoses: 8 (44%) invasive lobular carcinoma (ILC), 7 (39%) ductal carcinoma in situ (DCIS), and 3 (17%) invasive ductal carcinoma (IDC). Of the 18 malignant diagnoses, 16 (89%) occurred in 14 unique patients with concurrent BC. Based on the malignant MRI-guided CNB, 6 (46%) of these patients had additional (sentinel lymph node biopsy or contralateral breast surgery) or more extensive (wider lumpectomy) surgery.ConclusionIn this series, most MRI-guided CNB of the breast were benign. The vast majority of malignant diagnoses occurred in patients with concurrent BC and frequently resulted in changes in clinical management.

Project description:Organizing pneumonia (OP) is a clinicopathological entity that occurs idiopathically or in association with several conditions such as connective tissue diseases. Multicentric reticulohistiocytosis (MRH) is a systemic disease characterized by polyarthritis and mucocutaneous lesions, but lung involvement is uncommon. We report a patient with MRH associated with OP. This case may be of interest when considering the pathophysiological mechanisms of both diseases.
