Complicated Community-acquired Pneumonia Research Articles

Antibiotic route and outcomes for children hospitalized with pneumonia.

Emerging evidence suggests that initial oral and intravenous (IV) antibiotics have similar efficacy in pediatric community-acquired pneumonia (CAP), but further data are needed. We determined the association between hospital-level initial oral antibiotic rates and outcomes in pediatric CAP. This retrospective cohort study included children hospitalized with CAP at 43 hospitals in the Pediatric Health Information System (2016-2022). Hospitals were grouped by whether initial antibiotics were given orally in a high, moderate, or low proportion of patients. Regression models examined associations between high versus low oral-utilizing hospitals and length of stay (LOS, primary outcome), intensive care unit (ICU) transfers, escalated respiratory care, complicated CAP, cost, readmissions, and emergency department (ED) revisits. Initial oral antibiotics were used in 16% (interquartile range: 10%-20%) of 30,207 encounters, ranging from 1% to 68% across hospitals. Comparing high versus low oral-utilizing hospitals (oral rate: 32% [27%-47%] and 10% [9%-11%], respectively), there were no differences in LOS, intensive care unit, complicated CAP, cost, or ED revisits. Escalated respiratory care occurred in 1.3% and 0.5% of high and low oral-utilizing hospitals, respectively (relative ratio [RR]: 2.96 [1.12, 7.81]), and readmissions occurred in 1.5% and 0.8% (RR: 1.68 [1.31, 2.17]). Initial oral antibiotics varied across hospitals without a difference in LOS. While high oral-utilizing hospitals had higher escalated respiratory care and readmission rates, these were rare, the clinical significance of these small differences is uncertain, and there were no differences in other clinically relevant outcomes. This suggests some children may benefit from initial IV antibiotics, but most would probably do well with oral antibiotics.

Complicated pneumonia caused by group A Streptococcus in children - 2022/2023 infectious season outbreak and update on clinical characteristics

BackgroundAn increased incidence of group A Streptococcus (GAS) infections has been observed in pediatric population post-COVID-19 pandemic. While the majority of reports refer to scarlet fever or invasive GAS disease, detailed data on pulmonary manifestations such as complicated community-acquired pneumonia (CAP) are scarce. The aim of this study was to assess the contribution of GAS to complicated CAP in children during the 2022/2023 infectious season. MethodsWe retrospectively analyzed the etiology and clinical presentation of complicated CAP patients hospitalized in our tertiary care center in Warsaw, Poland, between August 2022 and May 2023. ResultsAmong 91 patients with complicated CAP, GAS was the dominant cause constituting 24.2% (22/91; 95% CI 15.8–34.3%) of the study group. 68.2% of GAS pneumonia patients presented symptoms of scarlet fever, and 27.3% had preceding or concurrent viral infection. GAS complicated CAP was associated with longer hospitalization, higher incidence of chest tube insertion, but shorter duration of chest tube drainage than complicated CAP of other etiology. Children with GAS complicated CAP had higher procalcitonin concentration (28.1 vs. 1.5 ng/dL; p<0.0001) and a lower platelets level (254.5 vs. 422 × 103/μL; p = 0.0031) than those with non-GAS infection. ConclusionsGAS is currently the predominant pathogen of complicated CAP in children. Clinicians should be aware of the current epidemiological situation and a more severe course of GAS pneumonia in this age group, and should monitor patients presenting with symptoms of scarlet fever and preceding viral infection closely.

Analysis of Childhood Pneumonia: A Comparison Between the Pre- and During the COVID-19 Pandemic in a Reference Hospital in Brazil.

Community-acquired pneumonia (CAP) is one of the most common causes of childhood morbidity and mortality, causing about two million deaths per year worldwide. The complicated CAP (CCAP) results from the worsening of CAP. Their incidence has reduced in the last 30 years due to vaccination. However, the coronavirus disease (COVID-19) pandemic reduced vaccination coverage, resulting in increased incidence of CCAP in 2021 and 2022. To analyze the clinical and epidemiological profile of CAP in children under five years of age in two periods: pre- (2018 to 2019) and during the COVID-19 pandemic (2020 to 2022). This cross-sectional retrospective study was conducted at the Professor Fernando Figueira Institute of Integral Medicine (IMIP). We analyzed the sociodemographic and clinical variables of children with CAP aged below five years who were admitted to IMIP from 2018 to 2022. Analysis encompassed the Pearson's Chi-square test, Fischer's exact test, and Student's T tests. A total of 468 children were analyzed: 382 in the pre-pandemic period and 86 during the COVID-19 pandemic. Concerning the antibiotic therapy, the most prescribed was Ampicillin (45.00%) in both periods. The combination of Oxacillin and Ceftriaxone was prescribed in 6.86% of cases in the pre-pandemic period; this value increased to 20.90% during the COVID-19 pandemic. Pleural effusion represented 12.10% of cases in the pre-pandemic period and 24.40% during the COVID-19 pandemic. The presence of pleural empyema went from 1.60% to 8.20%, and necrotizing pneumonia from 1.30% to 5.90% in the respective periods. Regarding ICU admission, 5.30% were admitted during the pre-pandemic period and 34.10% during the COVID-19 pandemic. Clinical suspicion of influenza presented a positivity rate of 17.60%. Children with CAP presented a higher frequency of complications during the COVID-19 pandemic. Further research is needed to find the cause of increased CAP complications in this period.

Mean platelet volume and D-dimer as predictors for complicated community-acquired pneumonia in hospitalized children

BackgroundCommunity-acquired pneumonia (CAP) is one of the primary causes of child mortality and morbidity. The primary objective of our research was to assess the value of mean platelet volume (MPV) and D-dimer levels in predicting complicated community-acquired pneumonia in hospitalized children.MethodsThis observational retrospective study gathered medical data from the electronic medical records of children diagnosed with CAP who were admitted to the Pediatric Pulmonology Unit between December 2021 and December 2022.ResultsThis study included 154 pediatric patients. Their age at presentation was 4.15 ± 3.60 years. A comparison of patients with complicated CAP and non-complicated CAP revealed a statistically significant decrease of MPV in the complicated CAP group than in the non-complicated group (p = 0.016). The D-dimer level was significantly higher in the complicated CAP 3.42 ± 3.02 µg/ml compared than in the non-complicated 1.63 ± 2.04 µg/ml, p = 0.002). Low MPV and increased D-dimer were powerful indicators of complicated CAP (OR 0.577, p = 0.021, OR 1.419, p = 0.003).ConclusionThe current study highlights that low MPV and high D-dimer levels can be useful predictors of pulmonary complications of CAP in children. However, prospective observational studies are needed to evaluate the changes in these predictors during the disease and assess the time needed for normalization.

Treatment of complicated bacterial pneumonia in children

Introduction: Community-acquired pneumonia (CAP) is one of the most common infectious diseases in pediatrics, and may be related to the direct occurrence of local complications such as empyema, necrotizing pneumonia, lung abscess or pleural effusion, which are directly related to worsening of the clinical aspect and prolongation of the hospitalization period. Methodology: A narrative review of the literature was carried out in the PUBMED database, using the following keywords: “Bacterial pneumonia in children”, “Complicated Pneumonia” and “Treatment”, with the time filter for the last 5 years (2019-2023). Results: From the research carried out, 408 articles were identified, of which, after applying inclusion and exclusion criteria, 12 were selected for analysis. Discussion: The main complications are related to specific complementary exams and assertive surgical or antimicrobial therapies that seek to avoid mortality, exacerbation of other complications and reduce hospitalization time and associated morbidities. Conclusion: Knowledge about the complications of community-acquired pneumonia, particularly its course of development and its propaedeutic approach, helps to alleviate the difficulties of the clinical context and provide more security to the doctor in his/her healthcare assistance to the patient.

Imaging of Acute Complications of Community-Acquired Pneumonia in the Paediatric Population-From Chest Radiography to MRI.

The most common acute infection and leading cause of death in children worldwide is pneumonia. Clinical and laboratory tests essentially diagnose community-acquired pneumonia (CAP). CAP can be caused by bacteria, viruses, or atypical microorganisms. Imaging is usually reserved for children who do not respond to treatment, need hospitalisation, or have hospital-acquired pneumonia. This review discusses the imaging findings for acute CAP complications and the diagnostic role of each imaging modality. Pleural effusion, empyema, necrotizing pneumonia, abscess, pneumatocele, pleural fistulas, and paediatric acute respiratory distress syndrome (PARDS) are acute CAP complications. When evaluating complicated CAP patients, chest radiography, lung ultrasonography, computed tomography (CT), and magnetic resonance imaging (MRI) can be used, with each having their own pros and cons. Imaging is usually not needed for CAP diagnosis, but it is essential for complicated cases and follow-ups. Lung ultrasound can supplement chest radiography (CR), which starts the diagnostic algorithm. Contrast-enhanced computed tomography (CECT) is used for complex cases. Advances in MRI protocols make it a viable alternative for diagnosing CAP and its complications.

1213. Application of Short Course Criteria for Community-Acquired Pneumonia (CAP) Among Patients Admitted Within a 17-community Hospital Telehealth Antimicrobial Stewardship Program (Tele-ASP)

Abstract Background A recent randomized controlled trial by Dinh et al. found three days of antibiotics was appropriate for certain community-acquired pneumonia (CAP) patients, but the real-world applicability of this study remains to be evaluated. In February 2022, a telehealth antimicrobial stewardship program (Tele-ASP) intervention was implemented across 17 small community hospitals to identify patients meeting clinical stability criteria used by Dinh et al. for short course therapy (3 days). An alert was implemented to notify the infectious diseases telehealth (Tele-ID) pharmacist of patients on room air for whom an antibiotic was ordered for pneumonia. Methods This IRB-approved study aimed to evaluate feasibility and impact of the intervention. Patients with severe or complicated CAP, known immunosuppression, or who were transferred were excluded. The primary outcome was total antibiotic duration. Secondary outcomes included whether the total duration was greater than 5 and 7 days and total IV antibiotic duration. Continuous antibiotic duration endpoints were assessed using Mann Whitney U and Fisher's Exact tests were used for categorical endpoints. Results Of 480 patients screened, only 148 (31%) patients met early clinical stability criteria. The primary reason for not meeting criteria was requirement of supplemental oxygen on Day 3 or greater on antibiotics (n=145). This proportion is far lower than previous studies, including that by Dinh et al., which found 60-70% patients met stability criteria. Of the 90 patients included, 27 patients had a Tele-ID review. Patients with an intervention were less likely to receive &amp;gt; 5 days of antibiotics (59% vs 73%) and &amp;gt; 7 days of antibiotics (19% vs. 32%), although these differences were not statistically significant. Conclusion This study relied on accuracy of oxygen charting, which may partly explain relatively lower proportion of patients meeting strict clinical stability criteria and likely limits feasibility of a scalable intervention. A pragmatically modified approach for this Tele-ASP intervention (i.e. allowance for no more than 1 unmet criterion) is an important area for further exploration and could improve the feasibility of a scalable telehealth intervention.

Increased susceptibility to complicated pneumonia among egyptian children with FokI (rs2228570), not TaqI (rs731236), vitamin D receptor gene polymorphism in association with vitamin D deficiency: a case-control study

BackgroundDetermining a genetic contribution to the development of complicated community-acquired pneumonia in children may help understand underlying pathogenesis. We aimed to investigate the association between two vitamin D receptor (VDR) gene polymorphisms, FokI and TaqI, and susceptibility to complicated pneumonia in Egyptian children compared to uncomplicated pneumonia. Associations with 25 hydroxy-vitamin D serum level were studied.MethodsThis was a case-control study that included 320 participants divided into 2 groups: patients and controls. The patients’ group included 100 children hospitalized with complicated pneumonia and 100 with uncomplicated pneumonia. 120 age and sex-matched apparently healthy children served as controls. The VDR FokI and TaqI polymorphisms were genotyped using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique. 25 hydroxy-vitamin D level was estimated in serum using ELISA.ResultsRegarding FokI, homozygous CC genotype was more common in complicated (52%) than uncomplicated pneumonia (28%) and controls (10%) (OR = 65; 95%CI (5.13-822.63), p < 0.001) and (OR = 4.3; 95%CI (0.7-27.16), p = 0.003), respectively. Children carrying C allele possessed 3 higher odds for complicated than uncomplicated pneumonia (OR = 3.08; 95%CI (1.33–7.14), p < 0.001). Heterozygous CT genotype increased susceptibility to complicated pneumonia (OR = 13.7; 95%CI (4.6–40.1), p < 0.001), not uncomplicated pneumonia (OR = 1.56; 95%CI (0.86–2.85), p = 0.145). Among complicated pneumonia, vitamin D level was lower in CC (6.92 ± 2.6ng/ml) than CT (9.55 ± 3.2 ng/ml) and TT genotype carriers (13.13 ± 3.6ng/ml) (p < 0.001). There was no significant difference between patients and controls as regards TaqI genotypes and alleles.ConclusionIn association with vitamin D deficiency, VDR gene FokI polymorphism, not TaqI, is a genetic risk factor for complicated pneumonia in Egyptian children.

Care-Seeking Behavior of Families of North Indian Children Suffering From WHO-Defined Severe Community-Acquired Pneumonia: A Hospital-Based Prospective Study.

Background Community-acquired pneumonia (CAP) is one of the leading causes of deathin children under five. In developing countries, delayed treatment seeking has been associated with mortality and morbidity. There are only a few studies in India evaluating care-seeking behavior, particularly in children with CAP. Methods The present study was a hospital-basedprospective semi-qualitative study. The study was conducted on parents or caregivers of consecutively hospitalized children under five (two to 59 months) with WHO-defined severe CAP along with radiological abnormalities consistent with CAP.Categorization of CAP and interpretation of chest X-rays (CXR) were done as per WHO criteria. Complicated CAP was categorized as severe pneumonia and had additional characteristics, including pleural effusion/empyema/pneumothorax requiring intercostal drainage, acute respiratory distress syndrome, or septic shock. Results After the screening of 420 consecutively hospitalized children under fivewith WHO-defined severe CAP along with radiological abnormalities consistent with it, 350 children were recruited in the present study. Among the recruited children, 58.6% experienced delayed care seeking, and among delayed care seekers, 94.6% presented with complications or developed complications during their hospital stay. The median delay in medical attention was three days. It also found that mothers with education levels below a high school had delayed care-seeking behavior. Mothers noticed the illness first in the majority of subjects (190, 54.3%), followed by fathers (78, 22.3%). Visiting traditional healers (46, 22.4%) and opting for home-bound remedies (44, 21.5%) were among the most common reasons for delayed care seeking. Fast breathing was the most concerning symptomamong the parents and caregivers of the hospitalized children due to severe CAP followed by retractions, cough,and drowsiness. Retractions, drowsiness, and inability to feed were significantly recognized as alarming symptoms by the parents and caregivers in children with complicated CAP. Delayed care-seeking behavior was more prevalent in families from rural areas than in urban areas. If decision takers were in closerelation with the sick child, chances of delayed care were less and vice versa. In urban areas, mothers can make decisions in significantly higher numbers than in rural areas, while grandmothers were more involved in decision-making in rural areas. Conclusion The delayed care-seeking behavior was significantly higher in children with complicated CAP. Delayed care-seeking behavior was more prevalent in families from rural areas than in urban areas. The most common reasons for delayed care-seeking behavior were home remedies and visiting traditional healers.Caregivers needto be more aware of the danger signs of CAP and the consequences of treatment delay.

Heparin-Binding Protein: A Prognostic Biomarker Associated with Severe or Complicated Community-Acquired Pneumonia in Children.

Heparin-binding protein (HBP) is a novel biomarker for inflammatory diseases. This study aimed to investigate the role of serum HBP in community-acquired pneumonia (CAP) in children and the association of HBP with the severity and prognosis. A total of 125 children with CAP admitted to the hospital were enrolled in this retrospective study. We analyzed the differences in clinical characteristics and examination findings between patients with different levels of HBP. The severe or complicated CAP was defined as having severe radiographic findings and/or systemic manifestations. Receiver operator characteristic (ROC) curves detected the performance of biomarkers in identifying patients with severe or complicated pneumonia. The multivariate logistic regression models assessed the association between HBP levels and the severity and prognosis. Finally, we constructed a predictive model based on HBP. The rate of severe or complicated CAP for patients with upper-quartile HBP concentration (≥60 ng/mL) was 54.8%, significantly higher than that of patients with lower HBP concentration (26.6%). The level of HBP is substantially correlated with neutrophil counts, C-reactive protein, erythrocyte sedimentation rate, and serum amyloid A protein (r = 0.31, 0.26, 0.36, and 0.26, respectively). HBP achieved the highest level of discrimination for severe or complicated CAP among the biomarkers. Higher HBP concentration (≥60 ng/mL) was associated with a three-fold higher risk of severe or complicated CAP (adjusted odds ratio = 3.11, p < 0.05). A predictive model including four characteristics (HBP, lactate dehydrogenase, age and non-viral infection) for predicting severe or complicated CAP (with area under the ROC curve = 0.75) was built to create a nomogram. Substantially elevated serum HBP is significantly associated with severe or complicated CAP and poor prognosis in children. This finding warrants further investigation of the function of HBP in the pathogenesis of CAP.

Empyema Thoracis in children: A Five-Year Analysis from a Tertiary Care Center in Eastern Nepal

Introduction: Complicated community-acquired pneumonia resulting in empyema thoracis remains the largest single cause of morbidity and mortality worldwide in children. This study was carried out to evaluate the clinical profile, associated complications and outcome of empyema thoracis in children. Methods: A retrospective study was conducted in the Department of Paediatrics at a tertiary care center in Eastern Nepal. A total of 106 children were managed with the diagnosis of complicated pneumonia with effusion or empyema thoracis from March 2017 to February 2021 (Five years). Only those patients who had clinico-radiological evidence of pleural effusion or empyema thoracis and received treatment with or without intercostal chest tube drainage (ICD) as the initial procedure were enrolled in the study. Besides supportive treatments and antibiotics; streptokinase was instilled intrapleurally in all the patients for three days. Patients who did not respond underwent VATS / decortication. Results: Majority of the children (60.19%) were below five years of age and were males (73.58%). Majority (55.67%) had a right-sided pleural effusion and fever was the predominant symptom (55.66%) at presentation. The pleural fluid culture was sterile in more than half (55.66%) of the patients with Staphylococcus aureus grown in 33.96%. The three most common complications were subcutaneous emphysema, thickened pleura, and pyo-pneumothorax. The success rate of medical management was 83.96% and the mortality was low (2.84%). Conclusions: The success rate of conservative management with antimicrobial therapy, intercostal drainage and fibrinolytics in this study was high (83.96%) with no major adverse effects of fibrinolytic therapy in empyema thoracis.

A Retrospective Chart Review of Pediatric Complicated Community-Acquired Pneumonia: An Experience in the Al Qassimi Women and Children Hospital.

Background Community-acquired pneumonia (CAP) is one of the most common global health issues. Even though many vaccinations and new diagnostic tools are available, CAP has a higher mortality rate, especially in children less than five years of age. Complicated CAP (CCAP) in a healthy child is a severe disease characterized by a combination of local complications, such as parapneumonic effusion (PPE), empyema (EMP), necrotizing pneumonia (NP), abscess, pneumothorax, and bronchopleural fistula, and systemic complications, such as bacteremia, metastatic infection, multiorgan failure, acute respiratory distress syndrome, disseminated intravascular coagulation, and, rarely, death. This study describes the demographic features, clinical presentation, management, and outcomes of patients diagnosed with CCAP at the Al Qassimi Women's and Children's Hospital (AQWCH). Methodology This retrospective chart review aims to collect and explore the data of all previously healthy children admitted with CCAP between the ages of one month and 13 years at AQWCH from January 2018 to December 2020. The primary study outcome measure is to provide clinicians with the diagnostics, evaluation, and management required to treat complicated pneumonia. Results A total of 195 patients were diagnosed with CAP, of whom 30 (15.3%) were diagnosed with CCAP. Of these, 14 (46.6%) patients had NP, eight (26.7%) had PPE, and eight (26.7%) had EMP. The median age of patients was 2.5 years, with 13 (43%) males and 17 (57%) females. The median duration of their stay in the hospital was 16 days. All patients were vaccinated with Hib, PCV13, or PCV7, and 57% of the patients received antibiotics before admission. The most common findings were consolidation and pleural effusion. Blood culture was negative in all cases, and pleural culture was positive only in three cases. A total of 17 (57%) patients underwent video-assisted thoracoscopic surgery (VATS), and post-VATS surgical emphysema was found to be the most common complication. Chest X-rays normalized after three months in 65% of patients. On comparing patients who were admitted to the Pediatric Intensive Care Unit (PICU) before any surgical intervention with those who were not, it was found that patients who required PICU admission were young (median = 2 years; interquartile range (IQR) = 1-4.5; p = 0.044) and had higher respiratory rate (mean = 49 breaths/per minute, standard deviation (SD) = 11; p = 0.000). In addition, they had lower median albumin (median = 2 g/L; IQR = 1.8-2.23; p = 0.004). On comparing patients who required VATS and those who did not require VATS, it was found that the former had a higher median respiratory rate (48 per min; range = 42-54; p = 0.01). A cavity in the chest computed tomography (CT) was found in 86% of patients with VATS (p = 0.017), and they had lower median albumin (median = 2 g/L; IQR = 1.92-2.24; p = 0.012), as well as longer median duration of using oral antibiotics (median = 21 days; IQR = 19-26; p = 0.025). Patients with complicated NP had a higher respiratory rate and higher PICU admission, and more cavity in the chest was found in the CT study. Most NP patients also underwent VATS and had longer median days of using oral antibiotics. One patient developed a bronchopleural fistula, and one patient diagnosed with NP died. Conclusions CCAP is a major cause of hospitalization in children. It is important to suspect CCAP in all CAP patients not responding to treatment after 48-72 hours.

Cardiovascular Complications in Community-Acquired Pneumonia.

Community-acquired pneumonia (CAP) is accountable for high mortality in both pediatric and adult populations worldwide, about one-third of hospitalized patients pass away within a year of being discharged from the facility. The high mortality and morbidity rates are closely related to cardiovascular complications that are consequent or concomitant to the acute episode of pneumonia. An updated perspective on the major pathophysiological mechanisms, prevalence, risk factors, outcomes, and relevant treatments of cardiovascular events in CAP patients is provided in the current study. It is possible to evaluate the pathophysiology of cardiac disease in this population based on plaque-related events, such as acute myocardial infarction, or events unrelated to plaque, such as arrhythmias and heart failure. With an absolute rate of cardiovascular problems ranging broadly from 10% to 30%, CAP raises the risk of both plaque-related and plaque-unrelated events. Both in- and out-patients may experience these issues at admission, throughout hospitalization, or even up to a year following discharge. At long-term follow-up, cardiac events account for more than 30% of deaths in CAP patients, making them a significant cause of mortality. If patients at risk for cardiac events are stratified, diagnostic tools, monitoring, and preventive measures may be applied to these patients. A prospective evaluation of cardioprotective treatments is urgently required from a research point of view.

Necrotizing pneumonia in children: Chest computed tomography vs. lung ultrasound.

BackgroundThe utilization of contrast-enhanced computed tomography (CT) of the chest for the diagnosis of necrotizing pneumonia (NP), a complication of community-acquired pneumonia, is controversial because of the inherent ionizing radiation involved. Over the past few years, the growing availability of bedside Lung Ultrasound (LUS) devices has led to increased use of this nonionizing imaging method for diagnosing thoracic pathology, including pneumonia.ObjectiveThe objectives of this study were as follows: first, to compare the performance of LUS vs. CT in the identification of certain radiological signs of NP, and second, to determine whether LUS could replace CT in the diagnosis of NP.Materials and methodsWe compared retrospectively the CT and LUS images of 41 patients between 2005 and 2018 in whom at least one contrast-injected chest CT scan and one LUS had been undertaken fewer than 7 days apart.ResultsPleural effusions were demonstrated almost systematically (100% on CT vs. 95.8% on LUS). Visualization of septations in pleural effusions was clearly superior on LUS (20.4% on CT vs 62.5% on LUS). Concerning the detection of necrosis, we observed a strong correlation between LUS and the gold-standard CT (95.8% on LUS vs. 93.7% on CT). Parenchymal cavities were more easily detected on CT than on LUS (79.1 vs. 35.4%).ConclusionLUS has shown to be as effective as CT in the diagnosis of NP. The use of CT in patients with NP could be limited to the detection of complications such as bronchopleural fistulae in unfavorably evolving diseases.

NSAID use and clinical outcomes in COVID-19 patients: a 38-center retrospective cohort study

BackgroundNon-steroidal anti-inflammatory drugs (NSAIDs) are commonly used to reduce pain, fever, and inflammation but have been associated with complications in community-acquired pneumonia. Observations shortly after the start of the COVID-19 pandemic in 2020 suggested that ibuprofen was associated with an increased risk of adverse events in COVID-19 patients, but subsequent observational studies failed to demonstrate increased risk and in one case showed reduced risk associated with NSAID use.MethodsA 38-center retrospective cohort study was performed that leveraged the harmonized, high-granularity electronic health record data of the National COVID Cohort Collaborative. A propensity-matched cohort of 19,746 COVID-19 inpatients was constructed by matching cases (treated with NSAIDs at the time of admission) and 19,746 controls (not treated) from 857,061 patients with COVID-19 available for analysis. The primary outcome of interest was COVID-19 severity in hospitalized patients, which was classified as: moderate, severe, or mortality/hospice. Secondary outcomes were acute kidney injury (AKI), extracorporeal membrane oxygenation (ECMO), invasive ventilation, and all-cause mortality at any time following COVID-19 diagnosis.ResultsLogistic regression showed that NSAID use was not associated with increased COVID-19 severity (OR: 0.57 95% CI: 0.53–0.61). Analysis of secondary outcomes using logistic regression showed that NSAID use was not associated with increased risk of all-cause mortality (OR 0.51 95% CI: 0.47–0.56), invasive ventilation (OR: 0.59 95% CI: 0.55–0.64), AKI (OR: 0.67 95% CI: 0.63–0.72), or ECMO (OR: 0.51 95% CI: 0.36–0.7). In contrast, the odds ratios indicate reduced risk of these outcomes, but our quantitative bias analysis showed E-values of between 1.9 and 3.3 for these associations, indicating that comparatively weak or moderate confounder associations could explain away the observed associations.ConclusionsStudy interpretation is limited by the observational design. Recording of NSAID use may have been incomplete. Our study demonstrates that NSAID use is not associated with increased COVID-19 severity, all-cause mortality, invasive ventilation, AKI, or ECMO in COVID-19 inpatients. A conservative interpretation in light of the quantitative bias analysis is that there is no evidence that NSAID use is associated with risk of increased severity or the other measured outcomes. Our results confirm and extend analogous findings in previous observational studies using a large cohort of patients drawn from 38 centers in a nationally representative multicenter database.

The role of lung ultrasonography in predicting the clinical outcome of complicated community-acquired pneumonia in hospitalized children.

This study's objective was to analyze lung ultrasonography (LUS) characteristics in hospitalized pediatric patients with complicated community-acquired pneumonia (CAP). We hypothesized that LUS could be correlated with the clinical outcome in these cases. In this retrospective study, we evaluated the LUS appearances (at admission and five days after the beginning of the treatment) and the progression of complicated CAP. We identified 45 patients who fulfilled the inclusion criteria. Several complications occurred in these subjects during follow-up including: serofibrinous pleurisy (62.2%), empyema (15.6%), encapsulated pleurisy (11.1%), lung abscess (6.7%) and necrotizing pneumonia (2.2%). In addition, 22.2% of the patients required surgical treatment: draining tube (11.1%), decortication (6.7%) and resection (4.4%). Intensive care unit admission was needed in 8.9% of patients. The median duration of hospitalization was 14 [9.7; 19.7] days. The thickness of pleural effusion with a cut-off value of 10 mm seen by LUS was a predictor for the need for continuous thoracic drainage (p<0.01), segmentectomy or thoracoscopic surgery (p=0.03) and prolonged hospitalization over 10 days (p<0.01). Hyperechogenic pleural effusion, presence of septa and fluid bronchogram on 1st LUS evaluation were independent predictors of segmentectomy or thoracoscopic decortication (p<0.01) and of longer hospitalization (p=0.02, p<0.01, p<0.01 respectively). The ultrasound characteristics of complicated CAP can offer valuable information to predict the clinical evolution of CAP and so can help the development of personalized medical management plans in these patients.

CT findings predicting lung resection in children with complicated community-acquired pneumonia.

To investigate computed tomography (CT) features which predict lung resection in children with complicated community-acquired pneumonia. A retrospective study of CT findings of patients with complicated pneumonia treated between January 2010 and December 2019. Fisher's exact test and ROC curves were used for statistical analysis. The study cohort consisted of 84 patients who underwent chest CT for complicated pneumonia. Lung resection was performed in 36 patients, 3 patients were treated by lung decortication, 45 patients were cured conservatively. Seven CT features were found statistically significant among the patients who underwent lung resection. 80.5% of patients from the resection group had two or more of these features on the initial CT scan, 64% had three or more. According to ROC analysis, simultaneous occurrence of multiple cavities equal to or greater than 3cm and lung abscess predicted a pulmonary resection. The combination of CT features which clearly predict lung resection are the simultaneous occurrence of multiple cavities ≥ 3cm and lung abscess. The most common triple combination of CT signs in the resected group of patients were multiple cavities ≥ 3cm, consolidation of lung tissue and pleural effusion < 3cm.

Risk factors for complicated community-acquired pneumonia in children.

Community-acquired pneumonia (CAP) in children continues to be one of the prominent causes of morbidity and mortality worldwide. By determining the risk factors associated with the development of complicated CAP (CCAP), new approaches for early diagnosis and effective treatment can be identified. This retrospective cohort study enrolled patients with CAP and CCAP who visited the pediatric ward of the study hospital between January 1,2017 and December 31,2017.For patients with CCAP, data regarding medical procedures performed surgical intervention, and hospitalization duration were collected. A total of 111 patients with CAP 93 (83.7%) and 18 (16.3%) with CCAP, aged between 3 months and 18 years were hospitalized due to severe pneumonia. The mean age of the patients was 3.6 ± 1.2 years, and 60 (54%) them were female. The mean age of patients with CCAP was higher than that of patients with CAP ((4.2 ± 3.3 vs. 2.8 ± 2.1 years, respectively); however, the difference was not significant (p=0.012). Patients with CCAP exhibited a significantly higher C-reactive protein level than those with CAP (10.06 ± 7.55 vs. 4.43 ± 3.37 g/L, respectively; p=0.007). Hypoxia upon admission was noted more commonly in the CCAP group than in the CAP group (p < 0.001). Findings related to hypoxia, respiratory distress, and pleural effusion on imaging are important distinguishing factors associated with the development of complications in patients hospitalized with CAP. Thus, CCAP etiology as well as early diagnosis and treatment approaches should be established and protective measures must be adopted.

Complicações da pneumonia adquirida na comunidade em crianças: fatores associados e a associação com falha terapêutica

OBJECTIVE: To analyze the prevalence of complications of community-acquired pneumonia (CAP) in children, to verify if there is an association of complications with therapeutic failure, and to analyze factors associated with them. METHODS: Cross-sectional, observational, retrospective review of medical records of children aged 0 to 17 years diagnosed with CAP, admitted to the general pediatric ward of the Pequeno Príncipe Hospital in Curitiba, from March 1, 2018 to March 1, 2019. Chronic lung diseases, neurological disorders, genetic diseases, heart disease, immunodeficiencies, hospital-acquired pneumonia, or incomplete data were excluded from the study. RESULTS: Of the 74 medical records chosen for the study, 54(73%) were children who did not develop complications and 20(27%) developed complications, in the following order of prevalence: pleural effusion 18(24.3%), empyema 7( 9.5%) and pulmonary necrosis 7(9.5%). Primary therapeutic failure, C-reactive protein (CRP) values, hemoglobin and rods collected at admission were associated with complications by Students t-test analysis with p-value &lt;0.05. It was not possible to identify an association of bacterial resistance and therapeutic failure because there was no bacterial growth in the cultures. CONCLUSION: The prevalence of CAP complications was 27%. Pleural effusion was the most common complication, followed by empyema and pulmonary necrosis. Complicated pneumonia was associated with therapeutic failure in 70% of cases (p=0.03). As it was not possible to identify the causative pathogen by blood culture, it is concluded that admission exams such as PCR, hemoglobin and rods can help in the direction of the empirical choice of antibiotic.

Possibilities of predicting lesions of the hepatobiliary system in children with community-acquired pneumonia

Annotation. The prognostic criteria of complications of community-acquired pneumonia and the possibility of developing disorders of the hepatobiliary system (HBS) depending on the concentration in the serum of the secretory leukocyte protease inhibitor (SLPI) were studied. The data of clinical and laboratory examination of 338 children with community-acquired pneumonia aged from one to three years were analyzed. Statistical processing of the results was performed using the system “IBM SPSS Statistica” 12 using parametric and non-parametric methods. It was found that in young children with pneumonia in the serum increases the concentration of SLPI, the level of which depends on the course and severity of pneumonia. It has been shown that the development of lobar pneumonia is significantly higher in patients from the SLPI cohort IV quartile (OR – 1.986, 95% CI – 1.864-2.356), compared with children from the cohort SLPI II and III quartile (OR – 0.476, 95% CI – 0.405- 0.559, OR – 0.494, 95% CI – 10.423-0.576, respectively). At the same time, at the values of SLPI at the level of III-IV quartile (OR – 1.923, 95% CI – 1.457-1.866) there is the development of community-acquired pneumonia. It was found that the development of pathological processes in the organs of HBS is associated with increased levels of SLPI. Thus, patients with polysegmental pneumonia and SLPI III/IV quartile (OR – 2.190, 95% CI – 1.810-2,754) are twice as likely to develop pathology of the hepatobiliary system than children with SLPI I/II quartile (OR – 1.153, 95% CI – 1.071-1.527). The established fact indicates the involvement of SLPI in the pathogenesis not only of pneumonia, but also in disorders of HBS.
