Abstract BackgroundEvidence indicates that single nucleoid polymorphisms (SNPs) of key molecules in innate immunity are related to clinical outcome of community-acquired pneumonia (CAP). Pentraxin 3 (PTX3) is a member of the acute-phase reactants superfamily and plays an important role against various diseases. The purpose of the current study was to assess the association between PTX 3 SNP and the risk of CAP.MethodsThis is a retrospective case-control study. Patients who were diagnosed with CAP between January 2018 to December 2019 in the Department of Pulmonary and Critical Care Medicine at Sun Yat-sen Memorial Hospital were included as CAP group. Then CAP cases were matched 1:1 by gender with non-infectious hospitalized patients during the same time. We detected the genotypes, allele frequencies and haplotype distributions of three SNPs within PTX3 gene (rs2305619, rs3816527, and rs1840680) by polymerase chain reaction sequencing in CAP group and control group, and compared their associations with the risk of CAP.ResultsThree SNPs in both groups were consist with Hardy-Weinberg equilibrium. A strong linkage disequilibrium was detected between any pair of rs2305619, rs3816527 and rs1840680 (|D’|≥0.85). There were no differences of rs2305619 and rs3816527 in genotypic distribution and haplotype frequency between CAP group and control group. However, we identified that SNP rs1840680 AA homozygote was associated with a lower risk of CAP in adults (OR, 0.32; 95% CI, 0.11-0.91; p = 0.03).ConclusionsOur findings suggested that PTX3 single nucleoid polymorphism was associated with the risk of CAP in adults.

Abstract Background: To identify the epidemiology and mortality predictors for severe childhood community-acquired pneumonia (CAP) and evaluate the influence of medications on clinical outcome in the real world.Methods: We performed a retrospective case-control study among children with severe CAP aged ≤5 years of age, separately comparing the detailed information between the in-hospital death cases and the survival cases in two different age groups. Multivariate regression model was used to figure out mortality predictors.Results: 945 children were recruited, including 604 infants and 341 young children. Overall 88 deaths occurred (9.3%). There was low adherence to guidelines in antimicrobials and carbapenems were widely served as initial empiric regimens, but the efficacy was not superior to the guidelines recommended. In multivariate analyses, very severe pneumonia (OR: 3.55; 95% CI: 1.39-9.09), lower birth weight (OR: 3.92; 95% CI: 1.50-10.23), severe underweight (OR: 4.72; 95% CI: 1.92-11.62), mechanical ventilation (OR: 5.06; 95% CI: 1.97-12.95；OR：14.43; 95% CI 3.31-62.96)，comorbidity including anemia (OR: 5.61; 95% CI: 2.36-13.35), neonatal asphyxia (OR: 6.03; 95% CI: 1.57-23.12), gastrointestinal hemorrhage (OR: 3.73; 95% CI: 1.21-11.48) and sedative-hypnotics ( OR: 4.32; 95% CI: 1.76-10.61; OR: 4.13; 95% CI：1.50-11.38) were independent risk factors for death, whereas a lower mortality was present in infants with probiotics (OR: 0.24; 95% CI: 0.10-0.54).Conclusions: Severe pneumonia remains a primary cause of death in children under 5 years of age. Clinical characteristics, comorbidity and medications are evidently associated with death. Importantly, we should pay particular attention to the identification of the mortality predictors and establish prophylactic measures to reduce the mortality.

ObjectivesThe clinical implications of blood eosinophil level in patients with chronic obstructive pulmonary disease (COPD) and community-acquired pneumonia (CAP) requiring invasive mechanical ventilation (IMV) and intensive care unit (ICU) admission are still unknown. Thus, this study aimed to compare the features of such patients with and without blood eosinophilia.DesignThis was a retrospective case–control study.SettingAn ICU of a medical centre in central Taiwan.ParticipantsA total of 262 patients with COPD and CAP requiring IMV and ICU admission.ResultsOf all participants (n=262), 32 (12.2%) had an eosinophil percentage (EP) >2% and 169 (64.5%) had an absolute eosinophil count (AEC) >300 cells/µL. Regardless of whether 2% or 300 cells/µL was used as a cut-off value, the eosinophilia group were slightly older (years) (82.9±5.4 vs 78.1±9.1, p=0.000 and 79.2±8.4 vs 77.6±9.6, p=0.246, respectively), and had a higher forced expiratory volume in 1 s/forced vital capacity (%) (56.0±8.0 vs 51.3±11.6, p=0.005 and 53.1±11.2 vs 49.5±11.2, p=0.013, respectively), less severe spirometric classification (p=0.008 and p=0.001, respectively), and lower white cell count 109/L (8.8±3.2 vs 11.1±4.9, p=0.009 and 10.3±4.4 vs 11.8±5.3, p=0.017, respectively) than the non-eosinophilia group. The bacteriology of endotracheal aspirates showed thatPseudomonas aeruginosaand other gram-negative bacilli were the most common organisms in all study groups. Participants with an EP >2% had a shorter ICU length of stay (OR=12.13, p=0.001) than those with an EP ≤2%, while an AEC >300 cells/µL was not associated with any in-ICUoutcomes.ConclusionsThe results of this study have significant clinical implications and should be considered when making treatment decisions for the management of patients with COPD and CAP requiring IMV and ICU admission.
