Front Med (Lausanne) 2022; 9:907727. [PMID: 35911397 PMCID: PMC9329540 DOI: 10.3389/fmed.2022.907727] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Accepted: 06/07/2022] [Indexed: 11/13/2022] Open
Abstract
Background We use longitudinal chest CT images to explore the effect of steroids therapy in COVID-19 pneumonia which caused pulmonary lesion progression. Materials and Methods We retrospectively enrolled 78 patients with severe to critical COVID-19 pneumonia, among which 25 patients (32.1%) who received steroid therapy. Patients were further divided into two groups with severe and significant-severe illness based on clinical symptoms. Serial longitudinal chest CT scans were performed for each patient. Lung tissue was segmented into the five lung lobes and mapped into the five pulmonary tissue type categories based on Hounsfield unit value. The volume changes of normal tissue and pneumonia fibrotic tissue in the entire lung and each five lung lobes were the primary outcomes. In addition, this study calculated the changing percentage of tissue volume relative to baseline value to directly demonstrate the disease progress. Results Steroid therapy was associated with the decrease of pneumonia fibrotic tissue (PFT) volume proportion. For example, after four CT cycles of treatment, the volume reduction percentage of PFT in the entire lung was −59.79[±12.4]% for the steroid-treated patients with severe illness, and its p-value was 0.000 compared to that (−27.54[±85.81]%) in non-steroid-treated ones. However, for the patient with a significant-severe illness, PFT reduction in steroid-treated patients was −41.92[±52.26]%, showing a 0.275 p-value compared to −37.18[±76.49]% in non-steroid-treated ones. The PFT evolution analysis in different lung lobes indicated consistent findings as well. Conclusion Steroid therapy showed a positive effect on the COVID-19 recovery, and its effect was related to the disease severity.

Abstract
We present the case of an 80-year-old woman with Mendelson's syndrome complicated by bacterial aspiration pneumonia caused by consciousness loss followed by vomiting resulting from putamen bleeding. Her condition worsened rapidly to develop respiratory failure, within a few hours; thereafter, she was intubated. Streptococcus agalactiae and Klebsiella oxytoca were detected from the aspirated sputum sample culture. She was diagnosed with acute respiratory distress syndrome with Mendelson's syndrome complicated by bacterial aspiration pneumonia. Corticosteroid and antibiotic administration improved her condition and led to successful extubation; therefore, these treatment modalities were invaluable. We suggest the clinical considerations for the corticosteroid and antibiotic use in such cases. We report a case of Mendelson's syndrome complicated by bacterial aspiration pneumonia. Use of steroids and antibiotics in such cases is controversial, however, they were reasonable choice in this case. We discussed this debatable issue in this case report.

Abstract
Influenza pneumonia, which causes acute respiratory distress syndrome and multiple organ failure, has no established management protocol. Recently, corticosteroid therapy was used to treat coronavirus disease 2019 with respiratory failure; however, its effectiveness as a treatment for influenza pneumonia remains controversial. To investigate the impact of corticosteroid therapy for the early phase of severe influenza pneumonia, we compared influenza pneumonia patients with respiratory failure treated with or without corticosteroids within 7 days after hospital admission using a Japanese nationwide administrative database. The primary endpoint was the mortality rate. The secondary endpoints were duration of intensive-care unit management, invasive mechanical ventilation, and hospital stay. The inverse probability weighting method with estimated propensity scores was used to minimize the data collection bias. We included 3519 patients with influenza pneumonia with respiratory failure. Of these, 875 were treated with corticosteroids. There was no significant difference between the groups regarding 30-day and 90-day mortality, duration of intensive-care unit management, invasive mechanical ventilation, and hospital stay. However, the in-hospital mortality rate was higher in the corticosteroid group. The use of systematic corticosteroid therapy in patients with influenza pneumonia was associated with a higher in-hospital mortality rate.

Abstract
There is broad interest in improved methods to generate robust evidence regarding best practice, especially in settings where patient conditions are heterogenous and require multiple concomitant therapies. Here, we present the rationale and design of a large, international trial that combines features of adaptive platform trials with pragmatic point-of-care trials to determine best treatment strategies for patients admitted to an intensive care unit with severe community-acquired pneumonia. The trial uses a novel design, entitled "a randomized embedded multifactorial adaptive platform." The design has five key features: 1) randomization, allowing robust causal inference; 2) embedding of study procedures into routine care processes, facilitating enrollment, trial efficiency, and generalizability; 3) a multifactorial statistical model comparing multiple interventions across multiple patient subgroups; 4) response-adaptive randomization with preferential assignment to those interventions that appear most favorable; and 5) a platform structured to permit continuous, potentially perpetual enrollment beyond the evaluation of the initial treatments. The trial randomizes patients to multiple interventions within four treatment domains: antibiotics, antiviral therapy for influenza, host immunomodulation with extended macrolide therapy, and alternative corticosteroid regimens, representing 240 treatment regimens. The trial generates estimates of superiority, inferiority, and equivalence between regimens on the primary outcome of 90-day mortality, stratified by presence or absence of concomitant shock and proven or suspected influenza infection. The trial will also compare ventilatory and oxygenation strategies, and has capacity to address additional questions rapidly during pandemic respiratory infections. As of January 2020, REMAP-CAP (Randomized Embedded Multifactorial Adaptive Platform for Community-acquired Pneumonia) was approved and enrolling patients in 52 intensive care units in 13 countries on 3 continents. In February, it transitioned into pandemic mode with several design adaptations for coronavirus disease 2019. Lessons learned from the design and conduct of this trial should aid in dissemination of similar platform initiatives in other disease areas.Clinical trial registered with www.clinicaltrials.gov (NCT02735707).

Abstract
Steroid-induced avascular necrosis of the femoral head (SANFH) is a mainly bilateral complication of steroid therapy that involves extensive necrosis, and frequently occurs in young and middle-aged individuals, with a high disability rate. Autophagy is an intracellular lysosomal degradation process occurring in numerous diseases. However, the effect of dexamethasone (DXM)-induced autophagy on osteoblasts is unclear. The aim of the present study was to investigate the effects of autophagy on SANFH. In the present study, femoral head of SANFH patients was collected, and the autophagy in the samples was evaluated. In addition, cell proliferation, membrane integrity and differentiation of osteoblasts were also detected to confirm the effect of DXM on a mouse osteoblasts cell MC3T3-E1 in vitro. Beclin 1 and microtubule-associated protein 1 light chain 3 were used as the markers of autophagy, while the autophagy inhibitor 3-methyladenine (3-MA) was used to investigate the role of autophagy in DXM-challenged osteoblasts. Immunohistochemistry results demonstrated that Beclin1 was markedly increased in the femoral head of SANFH patients. Furthermore, the treatment of osteoblasts with DXM decreased cell viability, increased lactate dehydrogenase activity in the cell culture supernatant, and reduced the alkaline phosphatase activity and bone morphogenetic protein-2 expression in osteoblasts in vitro. By contrast, 3-MA treatment attenuated the cell injury induced by DXM. The present study indicates that overactivated autophagy may be an important factor contributing to SANFH, and autophagy may be a potential target for the prevention of SANFH.

Abstract
Influenza pneumonia is associated with high number of severe cases requiring hospital and intensive care unit (ICU) admissions with high mortality. Systemic steroids are proposed as a valid therapeutic option even though its effects are still controversial. Heterogeneity of published data regarding study design, population demographics, severity of illness, dosing, type and timing of corticosteroids administered constitute an important limitation for drawing robust conclusions. However, it is reasonable to admit that, as it was not found any advantage of corticosteroid therapy in so diverse conditions, such beneficial effects do not exist at all. Its administration is likely to increase overall mortality and such trend is consistent regardless of the quality as well as the sample size of studies. Moreover it was shown that corticosteroids might be associated with higher incidence of hospital-acquired pneumonia and longer duration of mechanical ventilation and ICU stay. Finally, it is reasonable to conclude that corticosteroids failed to demonstrate any beneficial effects in the treatment of patients with severe influenza infection. Thus its current use in severe influenza pneumonia should be restricted to very selected cases and in the setting of clinical trials.

Abstract
Community-acquired pneumonia causes great mortality and morbidity and high costs worldwide. Empirical selection of antibiotic treatment is the cornerstone of management of patients with pneumonia. To reduce the misuse of antibiotics, antibiotic resistance, and side-effects, an empirical, effective, and individualised antibiotic treatment is needed. Follow-up after the start of antibiotic treatment is also important, and management should include early shifts to oral antibiotics, stewardship according to the microbiological results, and short-duration antibiotic treatment that accounts for the clinical stability criteria. New approaches for fast clinical (lung ultrasound) and microbiological (molecular biology) diagnoses are promising. Community-acquired pneumonia is associated with early and late mortality and increased rates of cardiovascular events. Studies are needed that focus on the long-term management of pneumonia.

Abstract
Serum interleukin (IL)-18 level was thought to be a useful as a predictor of refractory or severe Mycoplasma pneumoniae pneumonia, and steroid administration is reported to be effective in this situation. The serum levels of IL-18 correlated significantly with those of lactate dehydrogenase (LDH). The purpose of this study was to set a standard for the initiation of steroid therapy in M. pneumoniae pneumonia using a simple serum marker. We analyzed 41 adolescent and adult patients with refractory or severe M. pneumoniae pneumonia who received steroid therapy, and compared them with 108 patients with M. pneumoniae pneumonia who responded to treatment promptly (control group). Serum LDH levels were significantly higher in the refractory and severe group than in the control group at the initiation of steroid therapy (723 vs 210 IU/L, respectively; p < 0.0001). From receiver operating characteristic curve analysis, we calculated serum LDH cut-off levels of 364 IU/L at initiation of steroid therapy and 302 IU/L at 1-3 days before the initiation of steroid therapy. The administration of steroids to patients in the refractory and severe group resulted in the rapid improvement of symptoms and a decrease in serum LDH levels in all patients. Serum LDH level can be used as a useful parameter to determine the initiation of steroid therapy in refractory or severe M. pneumoniae pneumonia. A serum LDH level of 302-364 IU/L seems to be an appropriate criterion for the initiation of steroid therapy.

Abstract
Community acquired pneumonia (CAP) is a relevant public health problem, constituting an important cause of morbidity and mortality. It accounts for a significant number of adult hospital admissions and a large number of those patients ultimately die, especially the population who needed mechanical ventilation or vasopressor support. Thus, early identification of CAP patients and its rapid and appropriate treatment are important features with impact on hospital resource consumption and overall mortality. Although CAP diagnosis may sometimes be straightforward, the diagnostic criteria commonly used are highly sensitive but largely unspecific. Biomarkers and microbiological documentation may be useful but have important limitations. Evaluation of clinical response is also critical especially to identify patients who fail to respond to initial treatment since these patients have a high risk of in-hospital death. However, the criteria of definition of non-response in CAP are largely empirical and frequently markedly diverse between different studies. In this review, we aim to identify criteria defining nonresponse in CAP and the pitfalls associated with this diagnosis. We also aim to overview the main causes of treatment failure especially in severe CAP and the possible strategies to identify and reassess non-responders trying to change the dismal prognosis associated with this condition.

Abstract
Severe pneumonia has a high mortality (38.2%) despite evidence-based therapy. Rising rates of antimicrobial resistance increase the urgency to develop new treatment strategies. Multiple adjuvant therapies for pneumonia have been investigated but none are currently licensed. Profound immune dysregulation occurs in patients with severe infection. An initial hyper-inflammatory response is followed by a secondary hypo-inflammatory response with 'immune-paralysis'. There is focus on the development of immunostimulatory agents to improve host ability to combat primary infection and reduce secondary infections. Successful treatments must be targeted to immune response; promising biomarkers exist but have not yet reached common bedside practice. We explore evidence for adjuvant therapies in community-acquired pneumonia. We highlight novel potential treatment strategies using a broad-based search strategy to include publications in pneumonia and severe sepsis. We explore reasons for the failure to develop effective adjuvant therapies and highlight the need for targeted therapy specific to immune activity.

CLINICAL RESPIRATORY JOURNAL 2014; 8:410-6.

Abstract
INTRODUCTION Since February 2013, a novel reassortant H7N9 virus associated with human deaths, but no apparent outbreaks in poultry and wild birds has emerged in eastern China. OBJECTIVES The potential reemergence of H7N9 during next year's influenza season demand a further understanding of this important disease. METHODS Between March 1 and April 30, 2013, we obtained and analyzed clinical, epidemiologic and radiologic features, and virologic data from three laboratory-confirmed patients of A H7N9 infection admitted in Shanghai Ruijin Hospital. RESULTS All patients were middle to old aged (mean age 62 years) and overweight (mean body mass index 31) patients. Two patients were exposed to poultry directly or indirectly in food market. They presented with fever and rapidly progressive pneumonia that did not respond to antibiotics. Time between onset of symptoms and onset of respiratory failure (days) were 7-11 days. Two patients presented secondary invasive bacterial infections. All patients died on day 7 to day 86 after the onset of symptoms. CONCLUSIONS Cross species poultry-to-person transmission of this new reassortant avian influenza H7N9 virus can result in severe and fatal respiratory disease like acute respiratory distress syndrome (ARDS) in humans. Reduplicate chest imaging examination is suggested for risky patients with fever and dyspnea. Secondary invasive bacterial infections and pneumothorax can cause severe and fatal consequence. Old age, obesity and presence of comorbidity may be associated with increased mortality. Pulmonary fibrosis can be seen at late stage of the disease.
