    Abstract Background: Eosinophilic airway inflammation caused by respiratory virus infection has been demonstrated in basic research; however, clinical investigations are lacking. To clarify the extent to which respiratory virus infection induces airway eosinophilic inflammation, we reviewed the results of bronchoalveolar lavage (BAL) and respiratory virus testing performed at our hospital.
    Methods: Among the BAL procedures performed at the University of the Ryukyu Hospital from August 2012 to September 2016, we collected cases of acute respiratory disease in which multiplex polymerase chain reaction (PCR) was used to search for respiratory viruses. The effect of respiratory virus detection on BAL eosinophil fraction was analyzed using statistical analysis. A case study was conducted on respiratory virus detection, which showed an elevated BAL eosinophil fraction.
    Results: A total of 95 cases were included in this study, of which 17 were PCR-positive. The most common respiratory virus detected was parainfluenza virus (eight cases). The PCR-positive group showed a higher BAL eosinophil fraction than the PCR-negative group (p = 0.030), and more cases had a BAL eosinophil fraction > 3% (p = 0.017). Multivariate analysis revealed that being PCR-positive was significantly associated with BAL eosinophil fraction > 1% and > 3%. There were nine PCR-positive cases with a BAL eosinophil fraction > 1%, of which two cases with parainfluenza virus infection had a marked elevation of BAL eosinophil fraction and were diagnosed with eosinophilic pneumonia.
    Conclusions: Cases of viral infection of the lower respiratory tract showed an elevated BAL eosinophil fraction. The increase in eosinophil fraction due to respiratory virus infection was generally mild, whereas some cases showed marked elevation and were diagnosed with eosinophilic pneumonia. Respiratory virus infection is not a rare cause of elevated BAL eosinophil fraction and should be listed as a differential disease in the practice of eosinophilic pneumonia.

    Abstract It has been considered that idiopathic multicentric Castleman disease often involves pulmonary complications recognized as lymphocytic interstitial pneumonia. On the other hand, recent reports show that the computed tomography often show diffuse interstitial lung disease inconsistence with lymphocytic interstitial pneumonia. Pulmonary diseases with idiopathic multicentric Castleman disease are still rare and poorly understood. Here, we report a case of acute progressive diffuse interstitial lung disease, diagnosed as non-specific interstitial pneumonia, preceding idiopathic multicentric Castleman disease. A 65-year-old male visited our outpatient clinic for dyspnea on exertion. Imaging tests revealed interstitial lung disease showing non-specific interstitial pneumonia pattern, pulmonary function test proved the decline of vital capacity and laboratory tests showed increased fibrosis biomarkers; therefore, initially, he had been diagnosed as non-specific interstitial pneumonia. However, imaging tests also showed mediastinum lymphadenopathy, and laboratory tests revealed increased interleukin-6. Idiopathic multicentric Castleman disease was suspected. The lung and mediastinum lymph node biopsies were performed, and pathological findings of the lymph nodes were compatible with multicentric Castleman disease. Pathological findings of the lung showed that the fibrous thickening of interstitium and the collapse of alveoli. We diagnosed this case as idiopathic multicentric Castleman disease preceded by diffuse interstitial lung disease. Treatment with prednisolone improved the dyspnea, and the pulmonary lesions disappeared. The presented case suggests that interstitial lung disease could precede idiopathic multicentric Castleman disease. Chest physicians should be aware that idiopathic multicentric Castleman disease is one of the causative diseases of diffuse interstitial lung disease like non-specific interstitial pneumonia on the chest images.

    Abstract Coronavirus disease 2019 (COVID-19) is a global public health concern that can be classified as mild, moderate, severe, or critical, based on disease severity. Since the identification of critical patients is crucial for developing effective management strategies, we evaluated clinical characteristics, laboratory data, treatment provided, and oxygenation to identify potential predictors of mortality among critical COVID-19 pneumonia patients. We retrospectively utilized data from seven critical patients who were admitted to our hospital during April 2020 and required mechanical ventilation. The primary endpoint was to clarify potential predictor of mortality. All patients were older than 70 years, five were men, six had hypertension, and three ultimately died. Compared with survivors, non-survivors tended to be never smokers (0 pack-years vs. 30 pack-years, p = 0.08), to have higher body mass index (31.3 kg/m

    Abstract While the impact of respiratory virus infections has been well researched in some respiratory diseases, no clinical studies have discussed the subject of who would be more likely to develop respiratory virus infections among patients with various respiratory illnesses who come from different backgrounds. This study aimed to identify respiratory diseases that are frequently associated with respiratory virus infections along with the characteristics of patients who develop such infections in clinical settings. Tested specimens were obtained from the lower respiratory tract by bronchoscopy to provide more accurate data. Data of bronchoscopies at Ryukyu University Hospital between August 2012 and September 2016 were reviewed, and patients who underwent multiplex polymerase chain reaction (PCR) tests for detecting respiratory viruses in bronchoscopy specimens were retrospectively recruited for descriptive statistics. Differences among patients' primary pulmonary diseases and backgrounds were compared between the PCR-positive and -negative patients, and multivariate statistical analysis was performed to analyze factors associated with a positive PCR test result. Overall, 756 bronchoscopies were performed during the study period and PCR tests were performed for 177 patients. Of them, 27 tested positive for respiratory viruses, mainly parainfluenza virus and rhinovirus, and out of those, 7 were hospitalized for >1 month. Overall, all patients did not experience typical upper respiratory infection symptoms. In positive patients, 13 and 7 had diagnoses of interstitial lung disease and bacterial pneumonia, respectively. The diagnoses of 3 bacterial pneumonia cases were changed to viral pneumonia after receiving their PCR-positive tests. Respiratory virus infections were confirmed in 14 patients on immunosuppressant therapy and 4 on maintenance dialysis. Multivariate analysis revealed that immunosuppressant therapy and maintenance dialysis were independently associated with respiratory virus infections. Viruses were commonly detected in patients with interstitial lung diseases and bacterial pneumonia, while few patients were diagnosed with pure viral pneumonia. These illnesses were considered to be induced by respiratory infections. Immunosuppressant therapy and maintenance dialysis were associated with respiratory virus infections. Multiplex PCR testing is an essential diagnostic tool for respiratory virus infections in immunocompromised patients.

    Abstract Background and Objectives : Idiopathic pulmonary fibrosis (IPF) has a variable clinical course, which ranges from being asymptomatic to progressive respiratory failure. The purpose of this study was to evaluate the novel clinical parameters of IPF patients who receive an anti-fibrotic agent. Materials and Methods : From January 2011 to January 2021, we identified 39 IPF patients at Okinawa Chubu Hospital. Clinical information was obtained, such as laboratory data, pulmonary function test (PFT) results, and chest images, including of soft tissue thickness and the high-resolution computed tomography (HRCT) pattern at diagnosis. Results: The mean age was 72.9 ± 7.0 (53–85); 27 patients were men and 12 were women. The mean body mass index was 25.1 ± 3.9 (17.3–35). Twenty-four were active smokers and the median number of packs per year was 20. Regarding laboratory findings, mean white blood cell (WBC), lactate dehydrogenase (LDH), and Krebs Von den Lungen-6 (KL-6) values were 7816 ± 1859, 248 ± 47, and 1615 ± 1503, respectively. In PFT, the mean percent predicted FVC, percent predicted total lung capacity, percent predicted functional residual capacity (FRC), and percent predicted diffusion capacity of the lung for carbon monoxide (DLco) were 66.8 ± 14.9%, 71.8 ± 13.7%, 65 ± 39.6%, and 64.6 ± 27.9%, respectively. In chest radiological findings, soft tissue thickness at the right 9th rib was 26.4 ± 8.8 mm. Regarding chest HRCT patterns, 15 showed the definite usual interstitial pneumonia (UIP) pattern, 16 showed the probable UIP pattern, and eight showed the indeterminate for UIP pattern. In the treatment, 24 patients received pirfenidone and 15 patients took nintedanib. The mean observation period was 38.6 ± 30.6 months and 24 patients died. The median survival time was 32.4 months (0.9–142.5). Multivariate analysis adjusted for age showed that both soft tissue thickness [Hazard ratio (HR): 0.912, 95% confidence interval (CI): 0.859–0.979, p -value: 0.009] and percent FRC [HR: 0.980, 95% CI: 0.967–0.992, p -value: 0.002] were robust predictors of IPF mortality. Conclusions: In IPF patients treated with anti-fibrotic agents, both soft tissue thickness at the right 9th rib shown on the chest radiograph and %FRC can be novel predictors of IPF mortality.

    Abstract Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), has resulted in significant morbidity and mortality worldwide. Approximately 5% of COVID-19 patients who suffer from pneumonia develop critical respiratory failure. Here, we report the case of a healthy 52-year-old man who had respiratory failure owing to SARS-CoV-2 infection and was treated using femoro-femoral veno-venous extracorporeal membrane oxygenation (VV-ECMO) and prone position ventilation (PPV). After this treatment, his blood oxygen levels, chest high-resolution computed tomography findings, and clinical parameters significantly improved. He was decannulated from VV-ECMO on day 6 and finally extubated on day 11. To our knowledge, this is the first reported case of SARS-CoV-2-associated acute respiratory distress syndrome that was successfully treated with a combination of femoro-femoral VV-ECMO and PPV.

    Abstract Coronavirus disease 2019 (COVID-19) is a global public health concern that can be classified as mild, moderate, severe, or critical, based on disease severity. Since the identification of critical patients is crucial for developing effective management strategies, we evaluated clinical characteristics, laboratory data, treatment provided, and oxygenation to identify potential predictors of mortality among critical COVID-19 pneumonia patients. We retrospectively utilized data from seven critical patients who were admitted to our hospital during April 2020 and required mechanical ventilation. The primary endpoint was to clarify potential predictor of mortality. All patients were older than 70 years, five were men, six had hypertension, and three ultimately died. Compared with survivors, non-survivors tended to be never smokers (0 pack-years vs. 30 pack-years, p = 0.08), to have higher body mass index (31.3 kg/m2 vs. 25.3 kg/m2, p = 0.06), to require earlier tracheal intubation after symptom onset (2.7 days vs. 5.5 days, p = 0.07), and had fewer lymphocytes on admission (339 /µL vs. 518 /µL, p = 0.05). During the first week after tracheal intubation, non-survivors displayed lower values for minimum ratio of the partial pressure of oxygen to fractional inspiratory oxygen concentration (P/F ratio) (44 mmHg vs. 122 mmHg, p < 0.01) and poor response to intensive therapy compared with survivors. In summary, we show that obesity and lymphopenia could predict the severity of COVID-19 pneumonia and that the trend of lower P/F ratio during the first week of mechanical ventilation could provide useful prognostic information.
