The impact of the BIOFIRE® Blood Culture Identification 2 Panel on antimicrobial treatment of children with suspected systemic inflammatory response syndrome and sepsis.

This study aimed to assess the therapeutic effects of implementing the BioFire® Blood Culture Identification 2 (BCID2) Panel (bioMérieux, Marcy l'Etoile, France) in the clinical practice of children with sepsis. This retrospective cross-sectional study included children from 15 days of age to 18 years old with sepsis and of whom the BCID2 Panel was studied from the positive blood culture. If the antimicrobial treatment was changed according to the results of BCID2 Panel, it was recorded and re-grouped as targeted antimicrobial therapy, de-escalation of the antimicrobial treatment and shifting to another antimicrobial drug if any antimicrobial resistance was detected. Seven-days and thirty-days mortality rate was recorded. Thirty-two patients with 36 septic episodes with positive BCID2 Panel results were included. The median age was 10 months 15 days (ranging from 15 days to 16.5 years). The mean difference between having positive results by the BCID2 Panel and conventional culture methods was 82.2 ± 45.4 h (ranging from 12.3 to 207 h). Effect of the BCID2 Panel on the antimicrobial treatment was detected in 69.4% of the episodes (n = 25). Glycopeptides were ceased at 6 patients, piperacillin/tazobactam was ceased at 6 patients, and cefotaxime was ceased at one patient and de-escalation was achieved in 13 episodes which formed the 36.1% of the initial antimicrobial treatment.   Conclusion: The BCID2 Panel had an important impact on the patients care and optimization according to the principles of antimicrobial stewardship. The BCID2 Panel may be one of the key items for rapid and accurate diagnosis in children with sepsis. Blood culture is still the mainstay for especially detection of antimicrobial drug resistance, while BCID2 tests had several advantages such as speed and diagnostic accuracy as good as blood culture. What is Known: • The BioFire® Blood Culture Identification 2 (BCID2) Panel (bioMérieux, Marcy l'Etoile, France) is a well-validated assay that allows for the simultaneous identification of 43 nucleic acid targets associated with bloodstream infections within about 1 h. What is New: • BCID2 Panel had a direct impact on the patient's treatment decision at the 69.4% of the sepsis episodes. • The clinicians received the microbiological results 82.2 h earlier with BCID2 panel compared to blood culture methods with antimicrobial resistance and de-escalation of the antimicrobial drugs was achieved at 13 episodes which formed the 36.1% of the initial treatment.

BD Chloraprep™ ("2 % chlorhexidine with 70 % isopropyl alcohol") versus povidone iodine plus alcohol, for prevention of blood culture contamination at children: An investigator-initiated, open-label, single centre, randomized controlled trial.

INTRODUCTION: One of the important problems that lower the diagnostic value of blood culture is contamination with skin organisms. The povidone-iodine, alcohol, and chlorhexidine gluconate alcohol are used for disinfection prior to blood sampling for culture. METHODS: The investigator-initiated, open label, single centre, randomised trial compared blood culture contamination rates between two groups of patients in which using a povidone iodine skin-preparation process with the contamination rate for using "2 % chlorhexidine with 70 % isopropyl alcohol" skin-disinfection. The patients who required sampling for blood cultures were included in the study and study period was from 15 March 2023 to 15 July 2023. RESULTS: A total of 400 blood cultures were obtained during the study, including 133 in the study group and 267 in the control group. In the total blood cultures, 11.75 % (n = 47) had microorganism isolation. Among them 39 (9.75 %) were contaminants and 8 (2 %) of them were true pathogens. The contaminant microorganisms were as following; 34 coagulase-negative Staphylococci, 3 Micrococcus spp, and 2 Streptococci viridans. The blood culture contamination rate in the study group was 5.3 % (n = 7) and 12.0 % (n = 32) in the control group, and significantly lower in the study group (p = 0.033). There is no significant difference regarding skin related side effects between two groups. CONCLUSIONS: This study, showed that 2 % chlorhexidine gluconate in 70 % isopropyl alcohol is more efficacious in children than 10 % povidone-iodine preparations for disinfecting the skin prior to blood specimen collection for prevention of blood culture contamination.

Which Findings Make multisystem Inflammatory Syndrome in Children Different from the Pre-Pandemic Kawasaki Disease?

Multisystem Inflammatory Syndrome in Children associated with COVID-19 infection attracted attention because some features overlapped with Kawasaki disease. And due to these overlapping features with Kawasaki disease, it has become difficult to diagnose both disorders. Therefore, this study focused on the differences between the patients diagnosed with MIS-C after COVID-19 and Kawasaki patients analyzed, particularly during the pre-pandemic period. In this way, it is aimed to reduce the dilemmas experienced in Diagnosis. In this descriptive study, 98 patients diagnosed with MIS-C throughout the pandemic were compared to 37 patients diagnosed with Kawasaki Disease during the pre-pandemic period.The patients in the MIS-C group were older children and clinically suffered from more headaches, vomiting, diarrhea, abdominal pain, and chest pain than Kawasaki patients. Signs of shock such as hypotension and tachycardia were more remarkable. Also, myocarditis and mitral regurgitation were detected at a higher rate in the MIS-C group. Besides, in the laboratory, lymphopenia, hypoalbuminemia, and creatinine elevation were more apparent.In conclusion, our present study findings support that although the MIS-C and Kawasaki share common features, they present with different clinical and laboratory features. And these differences are thought to be supportive in treatment and patient management.

The Evaluation of Troponin I Levels and Myocarditis in Children with COVID-19: A Pediatric Single-Center Experience.

Children with COVID-19 usually show milder symptoms than adults; however, a minority of them may have cardiac involvement. We aimed to identify the role of troponin I levels that may predict early cardiac involvement in children with COVID-19. A single-center retrospective study was conducted to evaluate hospitalized children diagnosed with COVID-19 between March 11, 2020, and December 31, 2021. Patients with available troponin I levels and with no known cardiac disease were included. During the study period, 412 children with COVID-19 who had troponin I levels on admission were identified. Troponin levels were elevated in 7 (1.7%) patients and were normal in 395 (98.3%) patients. The median age of patients with elevated troponin levels was 4 (min. 2-max. 144) months, which was statistically lower than the age of patients with normal troponin levels (P = 0.035). All the patients with elevated troponin levels had tachycardia. Out of 7 patients with high troponin levels, 3 (42.9%) of them were admitted to the pediatric intensive care unit (PICU), 2 (28.6%) required oxygen support, and 1 (14.3%) required a mechanical ventilator. Patients with elevated troponin levels had a statistically longer hospital stay (P < 0.001). Neutropenia, tachycardia, PICU admission, oxygen support, and mechanical ventilation were statistically more common in patients with elevated troponin levels (P values were 0.033, 0.020, < 0.001, 0.050, and < 0.001, respectively). Electrocardiography (ECG) and echocardiography (ECHO) were performed on all patients with elevated troponin levels, and 6 (85.8%) patients were diagnosed with myocarditis. The ECG and ECHO have been performed in 58 (14.3%) out of 405 patients with normal troponin levels. Two (3.5%) patients had negative T waves on ECG, and all ECHOs were normal. Our results suggest that elevated troponin I levels in children with COVID-19 can be used to evaluate cardiac involvement and decide the need for further pediatric cardiologist evaluation.

Follow-Up of Cases with the Telemedicine Method During the COVID-19 Pandemic: An Alternative Strategy for Reduction of Hospital Workload and Hospital-Related Transmissions.

Background: This study evaluated the effect of telemedicine use in children with COVID-19 to reduce the workload of health care facilities. Methods: This study was conducted at Dr. Behçet Uz Children's Hospital between October and December 2020. The complaints of the children who were called because of positivity for severe acute respiratory syndrome-CoV-2-PCR were questioned and also the duration of talk was recorded. Children were classified according to their symptoms. Cases with severe symptoms were invited to the hospital and were hospitalized according to their clinical findings. Results: The median age of 506 patients reached was 10.8 ± 5.5. Phone calls lasted <3 min in 498 (98.6%) cases. Only 33 (6.5%) patients with severe symptoms were invited to the hospital, and 6 (18.2%) of these cases were hospitalized. Conclusion: During the pandemic, interviews with patients through telephone may help to reduce the patient burden and to prevent the contact of healthy individuals.

Evaluation of childhood hospitalization rates and degree of severity of SARS-CoV-2 variants, including B.1.1.7 (Alpha), B.1.315/P.1 (Beta/Gamma), and B.1.617.2 (Delta).

Severe acute respiratory syndrome coronavirus 2 is reappearing with an increasing number of variants every day; this study aimed to determine the effect of B.1.1.7 (Alpha), B.1.351 (Beta), P.1 (Gamma), and B.1.617.2 (Delta) variants on hospitalization rates. This single-center study was conducted at the University of Health Sciences Dr. Behçet Uz Children's Hospital from March 11 to August 27, 2021. Variant analyses of symptomatic patients admitted to the hospital who were found to be positive for COVID 19 PCR was performed. Out of 680 cases, 329 (48.4%) were B.1.1.7 variant, 17 (2.5%) were B.1.351/P.1 variant, and 165 (24.2%) were B.1.617.2 variant. One hundred and sixty-nine (24.9%) case variant analysis results were negative. The hospitalization rate of patients with the B.1.617.2 variant was 19.4%, the B.1.351/P.1 variant was 18%, the B.1.1.7 variant was 9.4%, and the negative variant was 10.1%. The B.1.617.2 (Delta) variant, which has become widespread all over the world recently, increases the rate of hospitalization in children.

Mucocutaneous Findings of Multisystem Inflammatory Syndrome in Children: A Single-Center Experience.

This descriptive study aimed to evaluate the frequency and the types of mucocutaneous manifestations associated with multisystem inflammatory syndrome in children (MIS-C). A cohort of 49 patients was reviewed. There were 6 patients (12.2%) whose mucocutaneous findings were observed by the clinicians on admission, whereas 26 (53%) patients had at least one of the histories of rash or desquamation associated with fever before the admission. Exanthems in our experience demonstrated a variety of morphologies, including morbilliform, urticarial, petechial, and maculopapular forms. Mucosal involvement (conjunctivitis and strawberry tongue) was observed only in 2/6 (34%) patients. In the coronavirus disease 2019 pandemic era, while evaluating the criteria for MIS-C, the history of previous cutaneous findings given by parents/caregivers is also important. There was no pathognomonic rash for MIS-C and a variety of cutaneous findings with a short lifespan can be associated with MIS-C.

The evaluation of the burden of multisystem inflammatory syndrome in children on health economics.

Objectives: This study aimed to evaluate the diagnostic tests and treatments applied in patients with multisystem inflammatory syndrome in children (MIS-C) and to determine the effect of the disease on health costs. Patients and methods: This retrospective cohort study included 59 MIS-C patients (40 males, 19 females; mean age: 7.7±4.2 years; range, 4 months to 16.5 years) who were admitted and treated between April 1, 2020, and November 1, 2021. Demographic and clinical features with hospital costs and length of stay were retrospectively reviewed from the medical files and computerized system of the hospital. Direct medical care costs of items were calculated with the hospital perspective using a combination of microcosting technique (resource-based accounting method) and hospital list data. Cases were classified as mild, moderate, or severe, and the patients were divided into two groups: the mild group and the moderate-severe group. Classification was determined by the vasoactive inotropic score (VIS), degree of respiratory support, and evidence of organ damage. Results: The mean age of the cases in the mild group was 6.5±3.7 years, and the mean age of the cases in the moderate-severe group was 9.2±4.3 years. Of 59 patients, 19 (32.2%) were followed up in the pediatric intensive care unit. The median duration of hospitalization in the hospital was 8 (interquartile range: 7-12) days. The total cost of the patients hospitalized with the diagnosis of MIS-C during the study period was 849,242.93$, and the mean cost per patient was 14,393.94±9,631.92$. In the distribution of the total cost of hospitalization according to expenses, the highest rate was pharmacy and blood products (51.99%) and IVIG costs (43.99%). While the mean total cost per person was 13,682.87±8,799.63$ in mild cases, it was 16,433.82±9,440.02$ in moderate-severe cases, and no statistically significant relationship was found between the two groups (p>0.05). There was no difference in the mean cost per patient between the cases with and without heart, lung, kidney, or neurologic involvement and advanced respiratory support (p>0.05). There was a strong positive correlation between the total costs and age (r=0.883, n=59, p<0.0001), with increased amount of costs with increased age. Conclusion: In the study, no statistically significant correlation was found between the total cost of per person in the mild group and the moderate-severe group (p>0.05). This finding may be due to the wide use of IVIG in MIS-C treatment, in addition to low transfer rates to pediatric intensive care units due to high-flow nasal cannula usage.

The impact of screening for tuberculosis exposure in the household in children with tuberculosis disease: A difficult riddle to solve.

BACKGROUND: Tuberculosis (TB) infection is transmitted by sharing the same airway with people with active TB. Children are often not considered the source of TB bacilli, and index case investigation is carried out after diagnosis. Here, we describe the impact of the presence of a household index case on childhood TB disease. METHODS: The data of patients aged between 1 month and 18 years who were diagnosed with TB were collected. We compared patients according to whether they had an index case in the household or not. RESULTS: A total of 202 TB patients were enrolled, of whom 62 (30.7%) had a household index case. There was no significant difference in having a household index case between TB patients under the age of five (23.3%) and older children (33.8%) (p = .140). Pulmonary TB was present in 61.4% of the cases, and extrapulmonary TB was present in 38.6% of the cases. The rate of patients who had a household index case was significantly higher in pulmonary TB (46.8%) compared to extrapulmonary TB (5.1%) (p < .001). Pulmonary TB patients with a history of household contact were more likely to have diagnostic radiological findings (93.1%) compared to those without (75.8%) (p = .009). However, pulmonary TB patients without household contact history had a higher rate of diagnostic microbiological findings (59.1%) and constitutional symptoms (63.6%) (p = .019 and p = .013, respectively). CONCLUSION: Household contact research is an important epidemiological tool. However, considering the contact rates in the household, new and more comprehensive public health programs are required to prevent the spread of childhood tuberculosis.

A hidden burden of disease in a specific group: Evaluation of COVID-19 seroconversion rates in pediatric patients with leukemia.

BACKGROUND: SARS-CoV-2, a respiratory viral disease, is thought to have a more severe course in patients with malignancy and low immune systems. METHODS: This prospective single-center study was conducted at the University of Health Sciences Dr Behçet Uz Children's Hospital from September 22 to December 31, 2021. Asymptomatic COVID-19 transmission rates were assessed using SARS-CoV-2 serology in patients with leukemia who had no history of COVID-19 infection. RESULTS: Among the 54 patients, 19 (35.2%) were females and 35 (64.8%) were males. The median age was 5.5 years (min 6 months, max 17 years). Forty-nine (90.5%) of the leukemia patients had acute lymphoblastic leukemia, while 5 (9.5%) had acute myeloid leukemia. Five of the 54 patients had a history of COVID-19 or contact with a positive person. SARS-CoV-2 IgG positivity was detected in 18 (36.7%) of 49 patients with no history of COVID-19 infection. DISCUSSION: Leukemia patients have a high seroconversion for SARS-CoV-2 without showing any symptoms supporting the asymptomatic course of COVID-19 infection in this risk group. CONCLUSION: As a result, patients with leukemia may have a high rate of COVID-19 seroconversion without showing symptoms.

Comparative Analysis of Pediatric Brucellosis Cases With and Without Bacteremia.

Introduction: Brucellosis, which is among the endemic regions of Turkey, is a common zoonotic disease. The gold standard in diagnosing brucellosis is culture. We aimed to compare demographic characteristics, risk factors, and clinical and laboratory variables between cases with culture positivity and undetected in culture. Materials and Methods: This single-center study was conducted between January 2007 and April 2022. Clinical and laboratory data of patients with brucella growth in blood culture and patients without growth were compared. Results: A total of 150 patients were included in the study. The median age was 10 (1-18 years). Of the patients, 66 (44%) were female and 84 (56%) were male. Forty (26.7%) of the patients were bacteremic and 110 (73.3%) were nonbacteremic. In the bacteremic group, white blood cell count, platelet, and hemoglobin counts were lower, and aspartate aminotransferase (AST) and alanine aminotransferase (ALT) values were higher. In clinical evaluation, fever, hepatomegaly, splenomegaly, and abdominal pain were more common in the bacteremic group. Conclusion: The distinction between bacteremic and nonbacteremic brucellosis can be predicted using laboratory values such as white blood cells, hemoglobin counts, platelet, ALT, and AST, and clinical findings such as fever, abdominal pain, hepatomegaly, and splenomegaly.

Readmission reasons of pediatric patients diagnosed with multisystem inflammatory syndrome after discharge.

Objectives: There is no clear information in the literature about causes of reactivation of multisystem inflammatory syndrome in children (MIS-C) or indications for readmissions for MIS-C after discharge; as a result, the conditions that may develop after infection in children with MIS-C were discussed, and the reasons for hospitalization were screened. Patients and methods: This single-center retrospective study was conducted with 95 patients (65 males, 30 females; mean age: 92.8±55.5 months; range, 5 to 17 months) between November 11, 2020, and December 30, 2021. Children who were rehospitalized in the study center after their discharge with the diagnosis of MIS-C were included in the study, and the indications for readmissions were evaluated. Results: During the study period, six (6.3%) patients (4 males, 2 females; median age: 114.5 months [interquartile range: 122 months]) had to be rehospitalized. Four of these patients had an underlying disease, while the other two were previously healthy children. Fever was the most common reason for readmissions in half of the patients, while the remaining patients were readmitted with the indications of myocarditis, pneumonia, and posttraumatic pain syndrome. Conclusion: Although no evidence for the reactivation of MIS-C was detected in patients in the literature, it should also be emphasized that close follow-up of these patients is a must, considering possible cardiac complications.

Can laboratory findings predict pulmonary involvement in children with COVID-19 infection?

BACKGROUND: Studies investigating clinical and imaging findings of coronavirus disease 2019 (COVID-19) pneumonia and predictors for lung injury mostly focus on adults. In this study, we aimed to evaluate the role of laboratory findings in predicting lung involvement in children with COVID-19. METHODS: Children with COVID-19 confirmed by reverse-transcription polymerase chain reaction or COVID-19 IgM and who underwent chest computed tomography (CT) scans were reviewed retrospectively. Admission absolute neutrophil count (ANC), absolute lymphocyte count (ALC), ANC/ALC ratio, platelet count, D-dimer, fibrinogen, ferritin, procalcitonin, C-reactive protein (CRP), and lactate dehydrogenase levels were compared in patients with normal and abnormal CT scans. RESULTS: A total of 101 children were included. Among the patients, 68 (67.3%) had normal CT scans, and 33 (32.7%) had pulmonary involvement. The median CRP, ferritin, and fibrinogen levels were significantly higher in children with abnormal CT findings. The model of binary logistic regression based on the presence of cough, shortness of breath, fibrinogen, ferritin, and CRP levels showed that the possibility of having abnormal CT was 1.021 times more likely for every one unit increase in fibrinogen levels. CONCLUSION: Fibrinogen might be useful to predict pulmonary involvement of COVID-19 in children. Restricting radiological imaging to patients with significant symptoms and high fibrinogen levels might be helpful in children with COVID-19 infections.
