Predictive Value of Adenoviral Load for Bronchial Mucus Plugs Formation in Children with Adenovirus Pneumonia. Can Respir J 2022; 2022:9595184. [PMID: 35979256 PMCID: PMC9377942 DOI: 10.1155/2022/9595184] [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: 01/12/2022] [Revised: 06/08/2022] [Accepted: 07/12/2022] [Indexed: 11/17/2022] Open
Abstract
Background. The study aimed to explore risk factors for bronchial mucus plugs (BMP) formation in children with adenovirus (AdV) pneumonia. Methods. A retrospective study was conducted on children with AdV pneumonia who underwent bronchoscopy from January 2019 to December 2019. Children were divided into the BMP group and the control group, depending on whether BMP was formed or not. The clinical information and treatment proposals of the two groups of children were counted and analyzed via multiple logistic regression analysis, ROC curve analysis, and correlation analysis. Results. Among 453 patients with AdV pneumonia, 185 (40.84%) were in the BMP group. Among all the cases, there were 188 patients with a single AdV infection, including 64 (34.04%) in the BMP group and 124 (65.96%) in the control group. The incidence of dyspnea, poor spirits, mixed infections, and other symptoms in the BMP group was higher than in the control group. Children in the BMP group had a longer heat range. C-reactive protein (CRP), lactate dehydrogenase (LDH), D-dimer (DD), and AdV load levels were higher in the MBP group. AdV load, Mycoplasma coinfection, DD, heat range, and LDH were independent risk factors for BMP, among which AdV load was the most significant (AUC = 0.819). AdV load was positively correlated with other risk factors, respectively. AdV load and heat range were independent risk factors for BMP patients with a single AdV infection. Conclusion. AdV load might have important clinical value in predicting BMP development in AdV pneumonia.

Abstract
Background Vitamin A plays a pivotal role in respiratory infection, accurate estimation of vitamin A status was recommended in planning and implementing interventions. As infections affect serum vitamin A productions, the real status need to be adjusted by acute phase protein (APP). Mycoplasma pneumoniae is an important cause of respiratory infection in children, the association between vitamin A concentrations and refractory Mycoplasma pneumoniae pneumonia (RMPP) remains unclear. Methods 181 MPP patients were enrolled in this retrospective study, adjusted vitamin A concentrations and other parameters were compared between RMPP and general-MPP (GMPP) patients. Multivariate logistic regression test was performed to evaluate the association between vitamin A levels and RMPP incidence, linear correlation tests were applied to evaluate correlation between vitamin A concentrations and fever duration, length of stay (LOS). Results Vitamin A concentrations in RMPP group were significantly lower than those in GMPP patients (P < 0.05), vitamin A (OR = 0.795, 95% C. I 0.669–0.946) and CRP (OR = 1.050, 95% C. I 1.014–1.087) were independently associated with RMPP incidence. Linear correlation tests found vitamin A concentrations were negatively correlated with fever duration and LOS (P < 0.001). Conclusions Serum vitamin A concentrations were independently associated with RMPP incidence, which may correlate with reduced incidence of RMPP.

Host Inflammatory Biomarkers of Disease Severity in Pediatric Community-Acquired Pneumonia: A Systematic Review and Meta-analysis. Open Forum Infect Dis 2019; 6:ofz520. [PMID: 31867405 PMCID: PMC6917028 DOI: 10.1093/ofid/ofz520] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2019] [Accepted: 12/04/2019] [Indexed: 12/29/2022] Open
Abstract
Background Community-acquired pneumonia (CAP) is the leading cause of death in children. Identification of reliable biomarkers offers the potential to develop a severity quantitative score to assist in clinical decision-making and improve outcomes. Methods A systematic review and meta-analysis was performed in PubMed and EMBASE on November 13, 2018, to examine the association between host inflammatory biomarkers and CAP severity in children. The inclusion criteria were case–control, cross-sectional, and cohort studies that examined candidate serum biomarkers. We extracted outcomes of interest, means, and standardized mean differences (SMDs) of plasma and serum levels of biomarkers together with information on disease severity. Meta-analysis was performed. This review was registered in the PROSPERO international registry (CRD42019123351). Results Two hundred seventy-two abstracts were identified, and 17 studies were included. Among the biomarkers evaluated, levels of C-reactive protein (CRP; SMD, 0.63; 95% confidence interval [CI], 0.35 to 0.91), interleukin (IL)-6 (SMD, 0.46; 95% CI, 0.25 to 0.66), IL-8 (SMD, 0.72; 95% CI, 0.15 to 1.29), neutrophil count (SMD, 0.27; 95% CI, 0.07 to 0.47), and procalcitonin (SMD, 0.68; 95% CI, 0.20 to 1.15) were substantially increased in severe CAP. In contrast, IL-2 concentrations (SMD, –0.24; 95% CI, –0.45 to –0.03) were higher in nonsevere CAP. Study heterogeneity was reported to be high (I2 > 75%), except for IL-2, IL-5, IL-6, and IL-12p70, which were classified as moderate (I2 = 50%–74%). Only neutrophil and white blood cell counts were described by studies exhibiting a low level of heterogeneity. Conclusions Our results suggest that host biomarkers, and especially CRP, IL-6, IL-8, and procalcitonin levels, have the potential to predict severe CAP in pediatric populations.

Int J Infect Dis 2019; 85:143-149. [PMID: 31170548 DOI: 10.1016/j.ijid.2019.05.030] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2019] [Revised: 05/23/2019] [Accepted: 05/25/2019] [Indexed: 12/17/2022] Open
Abstract
OBJECTIVE To investigate the prognostic value of phenylalanine and leucine in patients with severe infection. METHODS Ninety-three patients with infection who had a quick Sequential Organ Failure Assessment (qSOFA) score ≥2 were enrolled. Plasma phenylalanine, leucine, albumin, C-reactive protein, pre-albumin, and transferrin were measured and the SOFA score at enrollment was calculated after hospitalization. RESULTS During the 3-month follow-up, 30 (32.3%) patients died. Death was associated with higher SOFA scores, a higher incidence of bacteremia and admission to the intensive care unit, higher C-reactive protein and phenylalanine levels, worse kidney function, and lower pre-albumin and transferrin levels. Patients were categorized into three groups: high-risk type 1 (phenylalanine ≥84μM), high-risk type 2 (phenylalanine <84μM and leucine <93μM), and low-risk (other). Compared to the low-risk type patients, high-risk type 1 and 2 patients had higher mortality rates (hazard ratio 10.1 (95% CI 2.33-43.5) and hazard ratio 5.56 (95% CI 1.22-25.4), respectively). Type 1 patients had higher SOFA scores, a higher incidence of admission to the intensive care unit, and higher C-reactive protein and leucine levels. Type 2 patients had lower albumin and hemoglobin levels. Multivariable analysis showed that both high-risk types were independent predictors of death. CONCLUSIONS Phenylalanine- and leucine-defined risk classifications provide metabolic information with prognostic value for patients with severe infection.

Abstract
Objective To study the effect of the leukotriene receptor agonist montelukast combined with methylprednisolone on inflammatory response and peripheral blood lymphocyte subset content in children with mycoplasma pneumonia. Methods Seventy-four children were enrolled and randomly divided into a standard treatment group and a montelukast plus methylprednisolone group. Serum levels of inflammatory cytokines and corresponding cytokines of T lymphocyte subsets were measured, and peripheral blood was collected to determine the T cell subset content. Results At 3 days and 7 days after treatment, serum MCP-1, PCT, ICAM-1, CXCL8, CRP, IFN-γ, and IL-17 levels and peripheral blood Th1 and Th17 content were significantly decreased in both groups, while serum IL-4 and TGF-β levels and peripheral blood Treg and Th2 content were significantly increased. However, serum MCP-1, PCT, ICAM-1, CXCL8, CRP, IFN-γ, and IL-17 levels and peripheral blood Th1 and Th17 content were significantly lower while serum IL-4 and TGF-β levels and peripheral blood Treg and Th2 content were significantly higher in the montelukast plus methylprednisolone group compared with the control group. Conclusion Montelukast combined with methylprednisolone for the treatment of mycoplasma pneumonia can inhibit inflammatory responses and regulate levels of Th1/Th2 and Th17/Treg cells.

Radiologic Diagnosis and Hospitalization among Children with Severe Community Acquired Pneumonia: A Prospective Cohort Study. BIOMED RESEARCH INTERNATIONAL 2019; 2019:6202405. [PMID: 30729128 PMCID: PMC6343177 DOI: 10.1155/2019/6202405] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 11/15/2018] [Revised: 12/13/2018] [Accepted: 12/20/2018] [Indexed: 01/27/2023]
Abstract
Objectives This study was designed to assess the role of chest radiography for the diagnosis of pneumonia and assess the association of clinical characteristics with radiologic findings and predictors of hospitalization among children with severe community acquired pneumonia. Methods A prospective study was conducted on 122 children between ages of 3 month and 14 years admitted to pediatric emergency unit with diagnosis of severe pneumonia from September 1st to November 30th, 2017. Eligible children were subjected to chest radiography which was read by two senior radiologists independently (R1 and R2). Disagreements between R1 and R2 were resolved by a third senior radiologist (R3). Level of agreement between radiologists was assessed using Cohen's kappa coefficient. Clinical and laboratory parameters which could explain the variability in the duration of hospital stay were assessed using a linear regression mode. Independent predictors were assessed using multiple linear regression. Results The median age of the cohort was 10.0 months (interquartile range (IQR): 6.75-24.0); 76 (62.3%) were male. Nearly half, 63 (51.6%) did not have radiologic evidence of pneumonia. There was low level of agreement between R1 and R2 in reporting consolidation (kappa=0.435, p-value≤0.001), haziness (kappa=0.375, p-value≤0.001), and infiltration (kappa=0.267, p-value=0.008). Children with higher recorded temperature were more likely to have radiologic abnormalities suggesting pneumonia (p-value=0.033). The median duration of hospitalization was 3 days (IQR: 1-4 days); 118 (96.7%) were discharged with improvement. Height-for-age z-score (Coef.=0.203, R2=0.041, p-value=0.027); and hemoglobin level (Coef.=-0.249, R2=0.062, p-value=0.006) explained 4.1% and 6.2% of the variability in the duration of hospital stay, respectively. Conclusion Radiologic evidence of pneumonia was absent in half of the children with severe pneumonia. There was low agreement between senior radiologists in reporting chest radiographic findings, potentially necessitating harmonization activities to uniformly implement the WHO guidelines in reading chest radiographs.

Abstract
To evaluate the rationality of drug use to treat community-acquired pneumonia (CAP) in children of a Chinese hospital using a set of developed indicators.We performed a retrospective cross-sectional study in West China Second University Hospital. Hospitalized children (0-18 years old) diagnosed with CAP from October 2015 to January 2016 were included. A set of developed indicators for assessing rational drug use (RDU) to treat CAP in children were used to evaluate the rationality of drug use. The data of the indicators were compared with the recommendations of the available guidelines, analyzing the situation of drug use in the children diagnosed with CAP.Eight hundred ninety-four children were included, 99.4% of them received antibiotics and 87.4% received more than 1 antibiotic. Antibiotics were administered intravenously in 880 (99.0%) children. About 20 (2.2%) children received antiviral agents and 19 (2.1%) children received antiviral drugs combined with antibiotics. About 208 (23.3%) children received traditional Chinese medicines and the injection of traditional Chinese medicines was given in 20 (2.2%) children.This study illustrated that drug use was partly not consistent with the recommendations of current guidelines, especially antibiotics. The drug use of CAP in children needs to pay more attention to.

Abstract
Background Acute exacerbation of chronic obstructive pulmonary disease (AECOPD) has become an important disease of hospitalized elderly patients, which lack simple and inexpensive indicators for evaluating the condition and prognosis. This study was performed to investigate the clinical significance of the serum albumin/globulin ratio (AGR) in elderly patients with AECOPD. Methods The data of 252 hospitalized elderly patients with AECOPD, 89 stable COPD patients and 115 elderly healthy individuals were analyzed and compared. The differences in the AGR, logarithm of the serum C-reactive protein (LogCRP) level, prealbumin (PA) level, and immunoglobulin G (IgG) level were compared. AECOPD patients were grouped using the optimal cutoff values of each index to compare the difference in the combined infection rate. The correlation between hospital stays and AGR was analyzed. Results The AGR, LogCRP, PA level, and IgG level were different among the AECOPD group, stable COPD group and healthy control groups (P<0.05). The AGR, LogCRP, and PA level were different (P<0.05) among the Global Initiative for Chronic Obstructive Lung Disease (GOLD) I, II, II, and IV groups. Age, AGR, LogCRP, and PA level were different (P<0.05) between the infection and non-infection groups. After grouping according to the optimal cutoff values, the combined infection rate was different (P<0.05). The AGR was negatively correlated with the hospital stay (r=-0.583, P<0.001). The hospital stay was longer in patients with an AGR of <1.37 than ≥1.37 (P<0.001). Conclusions The AGR can be regarded as a reference index for evaluating the condition of elderly patients with AECOPD, determining the presence of combined infection, and predicting the prognosis.

Background. Lack of a gold standard for identifying bacterial and viral etiologies of pneumonia has limited evaluation of C-reactive protein (CRP) for identifying bacterial pneumonia. We evaluated the sensitivity and specificity of CRP for identifying bacterial vs respiratory syncytial virus (RSV) pneumonia in the Pneumonia Etiology Research for Child Health (PERCH) multicenter case-control study. Methods. We measured serum CRP levels in cases with World Health Organization-defined severe or very severe pneumonia and a subset of community controls. We evaluated the sensitivity and specificity of elevated CRP for "confirmed" bacterial pneumonia (positive blood culture or positive lung aspirate or pleural fluid culture or polymerase chain reaction [PCR]) compared to "RSV pneumonia" (nasopharyngeal/oropharyngeal or induced sputum PCR-positive without confirmed/suspected bacterial pneumonia). Receiver operating characteristic (ROC) curves were constructed to assess the performance of elevated CRP in distinguishing these cases. Results. Among 601 human immunodeficiency virus (HIV)-negative tested controls, 3% had CRP ≥40 mg/L. Among 119 HIV-negative cases with confirmed bacterial pneumonia, 77% had CRP ≥40 mg/L compared with 17% of 556 RSV pneumonia cases. The ROC analysis produced an area under the curve of 0.87, indicating very good discrimination; a cut-point of 37.1 mg/L best discriminated confirmed bacterial pneumonia (sensitivity 77%) from RSV pneumonia (specificity 82%). CRP ≥100 mg/L substantially improved specificity over CRP ≥40 mg/L, though at a loss to sensitivity. Conclusions. Elevated CRP was positively associated with confirmed bacterial pneumonia and negatively associated with RSV pneumonia in PERCH. CRP may be useful for distinguishing bacterial from RSV-associated pneumonia, although its role in discriminating against other respiratory viral-associated pneumonia needs further study.
