Lung ultrasound and procalcitonin, improving antibiotic management and avoiding radiation exposure in pediatric critical patients with bacterial pneumonia: a randomized clinical trial. Eur J Med Res 2024; 29:222. [PMID: 38581075 PMCID: PMC10998368 DOI: 10.1186/s40001-024-01712-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2022] [Accepted: 02/03/2024] [Indexed: 04/07/2024] Open
Abstract
BACKGROUND Pneumonia is a major public health problem with an impact on morbidity and mortality. Its management still represents a challenge. The aim was to determine whether a new diagnostic algorithm combining lung ultrasound (LUS) and procalcitonin (PCT) improved pneumonia management regarding antibiotic use, radiation exposure, and associated costs, in critically ill pediatric patients with suspected bacterial pneumonia (BP). METHODS Randomized, blinded, comparative effectiveness clinical trial. Children < 18y with suspected BP admitted to the PICU from September 2017 to December 2019, were included. PCT was determined at admission. Patients were randomized into the experimental group (EG) and control group (CG) if LUS or chest X-ray (CXR) were done as the first image test, respectively. Patients were classified: 1.LUS/CXR not suggestive of BP and PCT < 1 ng/mL, no antibiotics were recommended; 2.LUS/CXR suggestive of BP, regardless of the PCT value, antibiotics were recommended; 3.LUS/CXR not suggestive of BP and PCT > 1 ng/mL, antibiotics were recommended. RESULTS 194 children were enrolled, 113 (58.2%) females, median age of 134 (IQR 39-554) days. 96 randomized into EG and 98 into CG. 1. In 75/194 patients the image test was not suggestive of BP with PCT < 1 ng/ml; 29/52 in the EG and 11/23 in the CG did not receive antibiotics. 2. In 101 patients, the image was suggestive of BP; 34/34 in the EG and 57/67 in the CG received antibiotics. Statistically significant differences between groups were observed when PCT resulted < 1 ng/ml (p = 0.01). 3. In 18 patients the image test was not suggestive of BP but PCT resulted > 1 ng/ml, all of them received antibiotics. A total of 0.035 mSv radiation/patient was eluded. A reduction of 77% CXR/patient was observed. LUS did not significantly increase costs. CONCLUSIONS Combination of LUS and PCT showed no risk of mistreating BP, avoided radiation and did not increase costs. The algorithm could be a reliable tool for improving pneumonia management. CLINICAL TRIAL REGISTRATION NCT04217980.

Sono-Elastography: An Ultrasound Quantitative Non-Invasive Measurement to Guide Bacterial Pneumonia Diagnosis in Children. CHILDREN (BASEL, SWITZERLAND) 2023; 10:1335. [PMID: 37628334 PMCID: PMC10453076 DOI: 10.3390/children10081335] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 07/26/2023] [Accepted: 07/31/2023] [Indexed: 08/27/2023]
Abstract
Lung ultrasound (LUS) is, at present, a standard technique for the diagnosis of acute lower respiratory tract infections (ALRTI) and other lung pathologies. Its protocolised use has replaced chest radiography and has led to a drastic reduction in radiation exposure in children. Despite its undeniable usefulness, there are situations in which certain quantitative measurements could provide additional data to differentiate the etiology of some pulmonary processes and thus adapt the treatment. Our research group hypothesises that several lung processes such pneumonia may lead to altered lung tissue stiffness, which could be quantified with new diagnostic tests such as lung sono-elastography (SE). An exhaustive review of the literature has been carried out, concluding that the role of SE for the study of pulmonary processes is currently scarce and poorly studied, particularly in pediatrics. The aim of this review is to provide an overview of the technical aspects of SE and to explore its potential usefulness as a non-invasive diagnostic technique for ALRTI in children by implementing an institutional image acquisition protocol.

Abstract
OBJECTIVES Development of antimicrobial stewardship programs (ASPs) is strategy for prevention and management of emergence of antimicrobial-resistant organisms. In this study, we systematically reviewed the literature on antimicrobial stewardship interventions in PICUs and analyzed approaches, structure, implementation, and outcomes of the ASPs. DATA SOURCES PubMed and Scopus databases were systematically searched for studies published from January 1, 2007, to December 31, 2020, reporting interventions on judicious use of antimicrobials in PICUs (last search performed February 28, 2021). DATA SELECTION Studies that evaluated an intervention in a PICU setting or both in PICU and other settings and reported separate results for PICU were eligible for full-text review. Studies that had implemented stewardship in the entire hospital, including the PICU, but without presenting dedicated PICU data were excluded from the analysis. DATA EXTRACTION The strategy of intervention, structure of ASP team, implementation, and outcomes were assessed with a checklist tool for all studies included in the analysis. Risk of bias was assessed with the Cochrane Risk-of-Bias in Nonrandomized studies of Interventions tool. DATA SYNTHESIS Thirteen articles were found: 11 that applied ASP in PICUs, and two at hospital level. All PICU-dedicated ASPs applied a multimodal intervention combining strategies simultaneously; audit with feedback (6/11) and facility-specific clinical practice guidelines (7/11) were the most common strategies. A multidisciplinary team was formulated in all ASPs except for three biomarker-based interventions. Six of 11 studies included techniques to enhance behavior change and one implemented a behavior-based intervention. Antibiotic consumption was evaluated in all ASPs, cost in three of 11, antibiotic resistance in one of 11, length of hospitalization in six of 11, and mortality in eight of 11. All hospital-wide ASPs used audit with feedback in addition to facility-specific clinical practice guidelines and assessed antimicrobial consumption, expenditures, length of stay, and mortality. CONCLUSIONS The prevalence of ASPs in PICUs is limited, and few programs follow all of the currently available recommendations.

[PMID: 36340752 PMCID: PMC9627436 DOI: 10.4254/wjh.v14.i10.1907] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Revised: 08/22/2022] [Accepted: 10/11/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Respiratory syncytial virus (RSV) is a prevalent cause of lower respiratory tract infections. It may be associated with hepatocellular involvement, as indicated by increased liver enzymes aspartate aminotransferase and alanine transaminase (ALT).
AIM To evaluate the rate of increased liver enzyme levels in children with acute bronchiolitis and correlate them with clinical, laboratory, and radiological variables.
METHODS The study was a retrospective review of the medical records of children who presented with acute bronchiolitis when admitted to the Pediatric Department, Salmaniya Medical Complex, the Kingdom of Bahrain, between 2019 and 2020. We collected the demographic data, the clinical presentation, the laboratory and radiological findings, and the clinical outcomes. We compared the patients with elevated liver enzymes to those with normal levels at the time of presentation and at follow-up.
RESULTS We included 166 (57.8%) of 287 patients with acute bronchiolitis who fulfilled the inclusion criteria. Ninety-three (56%) patients were males. The median age at presentation was 3.4 (interquartile range 1.1 to 12.4) mo. Fifty-four (28%) patients tested positive for RSV, which was confirmed in 15 of them (28%) by PCR. Laboratory findings of 161 patients tested at presentation showed high ALT levels in 14 (8.7%) patients and normal ALT in 147 (91.3%). Coagulation profiles were measured in 46 (27.7%) of 166 patients. High prothrombin time was present in 15 (32.6%), a high international normalized ratio was present in 13 (28.3%), and high activated partial thromboplastin time was present in three (6.5%). Thrombin time was elevated in nine (27.3%) of 33 patients. Five (21.7%) of 23 patients with available radiological data had hepatomegaly; one of them had findings suggestive of fatty infiltration. High ALT had a significant association with lengthy hospital stays (P < 0.05) and positive urine culture (P < 0.05). Seventy (42.2%) patients had documented follow-up with liver function tests over a median follow-up period of 10.2 (IQR, 2.4-23.3) mo. Total serum protein and serum globulin levels were normalized at the follow-up time, with a significant P value of < 0.05.
CONCLUSION This study showed a low prevalence of liver function involvement in patients with acute bronchiolitis with a benign course. However, there was a rising trend in ALT during follow-up. Prolonged hospital stay and positive urine cultures were associated with elevated liver enzymes.

Ventilator-associated pneumonia is linked to a worse prognosis than community-acquired pneumonia in children. PLoS One 2022; 17:e0271450. [PMID: 35834521 PMCID: PMC9282450 DOI: 10.1371/journal.pone.0271450] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Accepted: 06/30/2022] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND Around 12-20% of patients with community-acquired pneumonia (CAP) require critical care. Ventilator-associated pneumonia (VAP) is the second cause of nosocomial infection in Paediatric Intensive Care Units (PICU). As far as we know, there are no studies comparing both types of pneumonia in children, thus it remains unclear if there are differences between them in terms of severity and outcomes. OBJECTIVE The aim was to compare clinical and microbiological characteristics and outcomes of patients with severe CAP and VAP. METHODS A retrospective descriptive study, including patients diagnosed of VAP and CAP, with a positive respiratory culture and under mechanical ventilation, admitted to the PICU from 2015 to 2019. RESULTS 238 patients were included; 163 (68.4%) with CAP, and 75 (31.5%) with VAP. Patients with VAP needed longer mechanical ventilation (14 vs. 7 days, p<0.001) and more inotropic support (49.3 vs. 30.7%, p = 0.006). Patients with VAP had higher mortality (12 vs. 2.5%, p = 0.005). Enterobacterales were more involved with VAP than with CAP (48 vs. 9%, p<0.001). Taking into account only the non-drug sensitive microorganisms, patients with VAP tended to have more multidrug-resistant bacteria (30 vs. 10.8%, p = 0.141) than patients with CAP. CONCLUSION Patients with VAP had worse prognosis than patients with CAP, needing longer mechanical ventilation, more inotropic support and had higher mortality. Patients with VAP were mainly infected by Enterobacterales and had more multidrug resistant microorganisms than patients with CAP.

Abstract
Background and Objectives. Acute bronchiolitis is a common respiratory disease in children. C-reactive protein (CRP) is an indicator of bacterial coinfection. This study is aimed at assessing the frequency of elevated CRP in children with acute bronchiolitis and at comparing the clinical characteristics, laboratory and radiological findings, antibiotics use, and outcome according to CRP levels. Material and Methods. We retrospectively reviewed medical records of children with acute bronchiolitis admitted to Pediatric Department, Salmaniya Medical Complex, Bahrain, in 2019-2020. Demographic, clinical, laboratory and radiological data, and outcomes were collected. Patients with high CRP were compared with those with normal levels. Results. Of 287 patients, 229 (79.2%) were included. 132 (57.6%) were males. Median presentation age was 3.7 (interquartile range (IQR), 1.27-12.33) months. Median CRP level was 10.4 (IQR, 2.8-35.1) mg/L. CRP was high in 167 (72.9%) patients. 17.6% (33/187 patients) had confirmed bacterial coinfection. Respiratory syncytial virus (RSV) was detected in 84 (36.7%) patients. Mean CRP level was higher in RSV-negative compared to RSV-positive patients,
versus
, respectively (
). Respiratory viral serology profile was positive in 34.7% (17/49 patients). 66.9% (107/160 patients) had positive chest X-ray. Antibiotics were used in 78.1% (179/227 patients). Thirteen (5.7%) patients required intensive care, five (2.2%) had surgical intervention, four (1.8%) required endotracheal intubation, and four (1.8%) died. Patients with high CRP were older at presentation (
) and had more fever (
) and cough (
), but lower hemoglobin level (
) compared to those with normal CRP. Fever (
) and hemoglobin level (
) were independent factors. Conclusion. Most children with acute bronchiolitis had high rate of elevated CRP values that did not correlate with the rate of bacterial coinfection. High CRP levels were found in older children, those presented with more fever and cough, and had a lower hemoglobin level despite that those factors were previously reported to be associated with disease severity and bacterial coinfection. This study also showed a high overall rate of antibiotic prescriptions in mostly viral disease.

Abstract
BACKGROUND Lung ultrasound (LUS) and procalcitonin (PCT) are independently used to improve accuracy when diagnosing lung infections. The aim of the study was to evaluate the accuracy of a new algorithm combining LUS and PCT for the diagnosis of bacterial pneumonia. METHODS Randomized, blinded, comparative effectiveness clinical trial. Children <18 years old with suspected pneumonia admitted to pediatric intensive care unit were included, and randomized into experimental group (EG) or control group (CG) if LUS or chest X-Ray (CXR) were done as the first pulmonary image, respectively. PCT was determined. In patients with bacterial pneumonia, sensitivity, specificity, and predictive values of LUS, CXR, and of both combined with PCT were analyzed and compared. Concordance between the final diagnosis and the diagnosis concluded through the imaging test was assessed. RESULTS A total of 194 children, with a median age of 134 (interquartile range [IQR]: 39-554) days, were enrolled, 96 randomized into the EG and 98 into the CG. Bacterial pneumonia was diagnosed in 97 patients. Sensitivity and specificity for bacterial pneumonia diagnosis were 78% (95% confidence interval [CI]: 70-85) and 98% (95% CI: 93-99) for LUS, 85% (95% CI: 78-90) and 53% (95% CI: 43-62) for CXR, 90% (95% CI: 83-94) and 85% (95% CI: 76-91) when combining LUS and PCT, and 95% (95% CI: 90-98) and 41% (95% CI: 31-52) when combining CXR and PCT. The positive predictive value for LUS and PCT was 88% (95% C:I 79%-93%) versus 68% (95% CI: 60-75) for CXR and PCT. The concordance between the final diagnosis and LUS had a kappa value of 0.69 (95% CI: 0.62-0.75) versus 0.34 (95% CI: 0.21-0.45) for CXR, (p < 0.001). CONCLUSIONS The combination of LUS and PCT presented a better accuracy for bacterial pneumonia diagnosis than combining CXR and PCT. Therefore, its implementation could be a reliable tool for pneumonia diagnosis in critically ill children.

Abstract
Objectives Procalcitonin is a useful biomarker for predicting bacterial infection after cardiac surgery. However, sometimes procalcitonin rises following cardiac surgery without a confirmation of bacterial infection. The aim was to analyse procalcitonin levels in children without a bacterial infection after cardiac surgery. Study design This is a prospective, observational study of children <18 years old admitted to the pediatric intensive care unit after cardiac surgery. Results 1,042 children were included, 996 (95.6%) without a bacterial infection. From them, severe complications occurred in 132 patients (13.3%). Procalcitonin increased differentially depending on the type of complication. Patients who presented a poor outcome (n = 26, 2.6%) had higher procalcitonin values in the postoperative period than the rest of patients (<24 hours: 5.8 ng/mL vs. 0.6 ng/mL; 24–48 hours, 5.1 ng/mL vs. 0.8 ng/mL, and 48–72 hours, 5.3 ng/mL vs. 1.2 ng/mL), but these values remained stable over time (p = 0.732; p = 0.110). The AUC for procalcitonin for predicting poor outcome was 0.876 in the first 24 hours. The cut-off point to predict poor outcome was 2 ng/mL in the first 24 hours (sensitivity 86.9%, specificity 77.3%). Patients with bacterial infection (n = 46) presented higher values of procalcitonin initially, but they decreased in the 48–72 hours period (<24 hours: 4.9 ng/mL; 24–48 hours, 5.8 ng/mL, and 48–72 hours, 4.5 ng/mL). Conclusions A procalcitonin value<2 ng/mL may indicate the absence of infection and poor outcome after cardiac surgery. The evolution of the values of this biomarker might help to discern between infection (where procalcitonin will decrease) and poor outcome (where procalcitonin will not decrease).

CHILDREN-BASEL 2021; 8:children8050351. [PMID: 33925182 PMCID: PMC8146464 DOI: 10.3390/children8050351] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/03/2021] [Revised: 04/16/2021] [Accepted: 04/25/2021] [Indexed: 11/16/2022]
Abstract
Despite the lack of evidence that bronchodilators, corticosteroids, and antibiotics are useful in treating bronchiolitis, their use is still widespread. This study aimed to determine the consumption of antibiotics for bronchiolitis before and after a procalcitonin-guided clinical pathway (CP) implementation. In December 2019, a CP for lower respiratory tract infection management was implemented at the Department of Women's and Children's Health at Padua University Hospital. This was a pre-post, quasi-experimental study that assessed the changes in the treatment of bronchiolitis during two bimesters preceding the CP implementation (pre-period: January 2018-February 2018 and January 2019-February 2019) and during the bimester after CP implementation (post-period January 2020-February 2020). After the CP implementation, there was a significant reduction in antibiotic prescriptions from 36.2% to 12.5% (p = 0.036) in patients hospitalized for bronchiolitis. Co-amoxiclav treatment, the antibiotic most commonly administered, decreased from 66.6% to 33.3%. Among outpatients' bronchiolitis episodes, a statistically significant decrease in beta2-agonists' use (from 18.0% to 4.4%, pre and post periods) and a quasi-significant decrease in corticosteroid use (from 8.0% to 0% pre and post periods) were observed. An evidence-based CP supported by educational lectures was associated with significant changes in the physicians' prescribing habits.
