Community-Acquired Pneumonia

Key clinical point: Development of bacteremia in immunocompetent adult patients managed in the ICU for severe pneumococcal community-acquired pneumonia (CAP) had no effect on mortality.

Main finding: In-hospital mortality (21.5% vs. 16.9%; P = .11) or baseline variables associated with in-hospital death, such as the age ≥65 years (P interaction = .45) and bilateral pulmonary infection (P interaction = .77), were not significantly different between patients with and without bacteremia.

Study details: This was a post hoc analysis of the prospective STREPTOGENE study including 614 immunocompetent adult white patients admitted to an ICU for severe pneumococcal CAP. Of these, 270 patients had a positive blood culture for Streptococcus pneumoniae at admission.

Disclosures: The study was sponsored by 2 public health care and research agencies: the Assistance Publique Hôpitaux de Paris and Délégation à la Recherche Clinique et au Développement. None of the authors declared any conflict of interests.

Key clinical point: Pneumococcal urinary antigen testing (PUAT) effectuated early de-escalation of broad-spectrum antibiotics among positive patients with community-acquired pneumonia (CAP) and thus should be widely performed to substantiate antimicrobial stewardship interventions.

Main finding: PUAT-positive patients showed a significantly shorter median (interquartile range) time to de-escalation vs. PUAT-negative patients (1 [0-2] days vs. 1 [1-2] days; P = .01) and a higher atypical (azithromycin or doxycycline) coverage discontinuation rate within 24 hours of PUAT (61.3% vs. 47.2%; P = .026), with no significant difference in methicillin-resistant Staphylococcus aureus agent discontinuation (P = .610) or antipseudomonal de-escalation (P = .895).

Study details: The data come from a retrospective chart review study including 910 adult patients who were hospitalized for CAP and, as part of the diagnostic procedure, underwent PUAT, which returned a positive result in 121 patients.

Disclosures: The authors reported no financial support or conflict of interests.

Key clinical point: Heparin-binding protein (HBP) may outperform the conventional biomarkers in predicting disease progression in children with severe community-acquired pneumonia (CAP).

Main finding: After adjusting for age, high HBP levels showed an independent correlation with respiratory failure (RF; odds ratio [OR] 1.008; 95% CI 1.003-1.013) in children with severe CAP. Among other biomarkers, HBP exhibited the highest predictive power for identifying children developing RF or sepsis, yielding areas under the receiver operating characteristic curves of 0.68 and 0.85, respectively, along with the best specificity at 96.3%.

Study details: Findings are from a retrospective observational study on 157 children who were admitted to an ICU ward for severe CAP, of which 106 presented with RF and 48 developed sepsis.

Disclosures: The study was sponsored by the Changsha Science and Technology Bureau Science Foundation, China. The authors declared no conflict of interests.

Main finding: Antibiotic retreatment rates in the 4-week period after hospital discharge in the lower dose vs. the higher dose group were 12.6% vs. 12.4% (difference 0.2%; 95% CI –∞ to 4.0%) and those in the shorter duration vs. the longer duration group were 12.5% vs. 12.5% (difference 0.1%; 95% CI –∞ to 3.9%).

Study details: Findings are from the CAP-IT trial including 814 children > 6 months old with CAP who were randomly assigned 1:1 after hospital discharge to receive the 4 possible combinations of amoxicillin dose (35-50 or 70-90 mg/kg) and duration (3 or 7 days).

Disclosures: The trial was funded by the National Institute of Health Research (NIHR) Health Technology Assessment (HTA) Program and Antimicrobial Resistance Themed Call. Some of the authors including the lead author reported receiving research grants from the NIHR/HTA.

Key clinical point: Antimicrobial stewardship intervention emerged successful in advocating a shift from broad-spectrum to narrow-spectrum antibiotics for treating moderately severe community-acquired pneumonia (CAP) while averting any safety concerns.

Main finding: Antimicrobial stewardship intervention effectuated a decrease in the adjusted mean broad-spectrum days of therapy per patient from 6.5 days to 4.8 days, with an adjusted relative reduction of 26.6% (95% CI 18.0%-35.3%). The adjusted risk difference of 0.4% (90% CI –2.7% to 2.4%) indicated noninferiority.

Study details: The data come from the investigator-initiated, noninferiority, CAP-PACT trial including 4,084 adult patients receiving antibiotics for moderately severe CAP post admission to a non-ICU hospital ward, of whom 2,235 patients were admitted during the control period and 1,849 during the intervention period.

Disclosures: The authors received no financial support for the study. CH van Werkhoven reported receiving grants, personal fees, and nonfinancial support from a few sources outside the study, in addition to obtaining a patent for the prediction of clinical manifestations of gut microbiota.
