Inhaled antibiotics in children with tracheostomy tubes: A descriptive study. Pediatr Pulmonol 2023; 58:1028-1033. [PMID: 36541025 DOI: 10.1002/ppul.26288] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 11/07/2022] [Accepted: 12/19/2022] [Indexed: 12/24/2022]
Abstract
INTRODUCTION Respiratory tract infections (RTIs) are common in children with tracheostomy tubes. Anecdotally, inhaled antibiotics are commonly prescribed, although to date there are no studies describing their use in this patient population. The objective of this study was to assess the variability of this practice at a single tertiary care children's hospital. METHODS All children admitted to our hospital with a tracheostomy tube who were prescribed inhaled antibiotics between 2013 and 2020 were included. Patient characteristics and data regarding inhaled antibiotic use were obtained retrospectively from the electronic medical record. RESULTS A total of 424 courses of inhaled antibiotics were prescribed during the study period. 296 (69.8%) courses were prescribed to treat an acute RTI, whereas 128 (30.2%) were prescribed prophylactically to prevent RTIs. 58.9% of children with tracheostomy tubes hospitalized during the study period received at least one course of inhaled antibiotics. The most common antibiotics prescribed were tobramycin and gentamicin; several different doses were used. In 53.2% of treatment courses, inhaled antibiotics were co-prescribed with systemic antibiotics. Therapy duration for treatment varied from 3 to 28 days. Respiratory cultures were used variably and antimicrobial susceptibility was often not taken into account when prescribing inhaled antibiotics. CONCLUSIONS Inhaled antibiotics were frequently prescribed as treatment and prophylaxis in children with tracheostomy tubes at our center, with significant variation in the prescribed antibiotic type, dose, frequency, duration, and co-prescription with systemic antibiotics. Prospective studies are needed to define best practice regarding inhaled antibiotics in this patient population.

Abstract
ABSTRACT A 57-year-old man with newly diagnosed with prostate cancer was admitted to our department for 68 Ga-prostate-specific membrane antigen PET/CT imaging. The patient, who was asymptomatic at the time of imaging, had increased diffuse 68 Ga-prostate-specific membrane antigen uptake in the trachea on PET/CT. No ground-glass density suggestive of pneumonia in both lungs was observed. The patient, whose symptoms developed 2 days after PET/CT imaging, was diagnosed with coronavirus disease 2019 by real-time polymerase chain reaction.

Tracheitis hospital admissions are associated with Asia dust storm. INTERNATIONAL JOURNAL OF ENVIRONMENTAL HEALTH RESEARCH 2022; 32:1337-1343. [PMID: 33508951 DOI: 10.1080/09603123.2021.1879740] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/31/2020] [Accepted: 01/18/2021] [Indexed: 06/12/2023]
Abstract
The risks of tracheitis have been widely studied, but no investigation has yet to assess the impact of air pollutants on tracheitis hospital admissions. This research explores the relationship between Asia dust storm (ADS) and tracheitis hospital admissions, by using a Poisson time-series model on the 2000-2012 National Health Insurance Research Database (NHIRB) from Taiwan and linking air pollutants and temperature data. From a total of 126,013 tracheitis hospital admissions, the average number of daily tracheitis hospital admissions is 26.53 and increases 10% notably one day after ADS. The empirical result shows that ADS does significantly affect tracheitis hospital admissions 3 and 5 days after an event for the overall sample and 2-4 days after it for females. For the age group <45, the number significantly increases 3-4 days after ADS, revealing that ADS has a prolonged effect on tracheitis hospital admissions.

Diagnosis, management, and outcomes of pediatric tracheostomy-associated infections: A scoping review. Pediatr Pulmonol 2022; 57:1145-1156. [PMID: 35229491 PMCID: PMC9313552 DOI: 10.1002/ppul.25873] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/25/2021] [Revised: 02/15/2022] [Accepted: 02/27/2022] [Indexed: 11/14/2022]
Abstract
BACKGROUND Children with tracheostomy are frequently admitted to the hospital for tracheostomy-associated respiratory infections (TRAINs). However, there remains a paucity of evidence to direct the diagnosis, treatment, and prevention of TRAINs. An important first step to addressing this knowledge gap is to synthesize existing data regarding TRAINs to inform current practice and facilitate innovation. DATA SOURCES We searched PubMed, Embase, Cochrane Library, CINAHL, and Web of Science from inception to October 2020. Original research articles and published abstracts including children and young adults 0-21 years of age with tracheostomy were included. Included studies assessed the clinical definitions of and risk factors for TRAINs, microbiologic epidemiology and colonization of tracheostomies, and treatment and outcomes of TRAINs. DATA SYNTHESIS Out of 5755 studies identified in the search, 78 full-text studies were included in the final review. A substantial number of studies focused on the detection of specific pathogens in respiratory cultures including Pseudomonas aeruginosa. Several different definitions of TRAIN including clinical, microbiologic, and laboratory testing results were utilized; however, no uniform set of criteria were identified. The few studies focused on treatment and prevention of TRAIN emphasized the role of empiric antimicrobial therapy and the use of inhaled antibiotics. CONCLUSIONS Despite a growing number of research articles studying TRAINs, there is a paucity of prospective interventional trials to guide the diagnosis, treatment, and prevention of respiratory disease in this vulnerable population. Future research should include studies of interventions designed to improve short- and long-term respiratory-related outcomes of children with tracheostomy.

Enteral antipseudomonal fluoroquinolones for ventilator-associated tracheobronchitis in children with pre-existing tracheostomy. Pediatr Pulmonol 2022; 57:1064-1071. [PMID: 34989477 DOI: 10.1002/ppul.25816] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/17/2021] [Revised: 01/03/2022] [Accepted: 01/04/2022] [Indexed: 11/08/2022]
Abstract
INTRODUCTION Pseudomonas aeruginosa is the most commonly isolated organism in tracheostomy-dependent children with ventilator-associated tracheobronchitis (VAT). Enteral treatment with an antipseudomonal fluoroquinolone such as ciprofloxacin or levofloxacin is sometimes employed, but supportive data are limited. The purpose of this study was to evaluate the effectiveness and safety of enteral antipseudomonal fluoroquinolones for VAT in children with pre-existing tracheostomy. METHODS This was a retrospective review of electronic medical records for tracheostomy-dependent children <18 years of age who received an enteral antipseduomonal fluoroquinolone for the treatment of presumed VAT from January 2013 through January 2020 at an academic children's hospital. RESULTS Seventy-six treatment courses representing 60 children (median age: 9.5, interquartile range [IQR]: 3.6-13.1 years) received an antipseudomonal fluoroquinolone for VAT treatment during the study period. Median treatment duration was 8 (range: 7-10) days. Most tracheostomy cultures (n = 70/82, 85%) were polymicrobial, with P. aeruginosa most commonly isolated (n = 67/224 organisms, 30%). Sixty-five courses (86%) were successfully treated with an enteral fluoroquinolone. Antibiotics were changed or extended for two (3%) children. Antibiotics were prescribed for 10 (13%) courses and eight (11%) required hospitalization for a respiratory infection within 30 days of fluoroquinolone completion. Six (8%) courses received a seizure rescue medication, seven (9%) experienced emesis, and one (1%) had elevated transaminases. Tendonitis and tendon rupture were not observed. CONCLUSIONS The results of this study suggest enteral antipseudomonal fluoroquinolones may be effective for the treatment of VAT in children with tracheostomy. Further study is warranted to clarify the role of these agents in pediatric VAT.

Abstract
Although the incidence is declining in the western world, Mycobacterium tuberculosis remains one of the most common infectious organisms responsible for significant morbidity and mortality worldwide. Pulmonary tuberculosis (TB) is the most commonly seen presentation; however, TB can affect nearly any of the body's organ systems. Endobronchial TB (EBTB) can complicate pulmonary TB or more rarely present as an isolated finding. It is essential to recognize and treat this condition promptly, as it can develop into tracheobronchial stenosis and chronic respiratory failure. Here we discuss the case of a 43-year-old female with a left upper lobe cavitary lesion who presented with weight loss, dyspnea, and hoarseness. After failing multiple courses of antibiotics, the patient underwent bronchoscopy, and pseudomembranous tracheobronchitis (PMTB) was diagnosed. Cultures of endobronchial samples grew Mycobacterium tuberculosis. Standard anti-TB quadruple therapy was initiated, and the patient clinically improved. Several subtypes of EBTB have been identified earlier. However, to the best of our knowledge, tuberculous PMTB has not previously been reported. This case allows us to consider the diagnostic and therapeutic implications of this condition.

Abstract
Pulmonary extra-intestinal manifestations of inflammatory bowel disease are rare, comprising 0.21% to 0.4% of the inflammatory bowel disease population. Common symptoms include cough, chest pain, and dyspnea. Abnormal pulmonary function tests are common in these patients, with restrictive, obstructive, and diffusion capacity defects. CT scanning remains the most sensitive imaging technique to detect abnormalities. Pulmonary manifestations are diverse and include airway, parenchymal, and pleural disease. Large airway disease predominates, particularly bronchiectasis. Upper airway disease is rare but concerning for the development of acute airway compromise. To our knowledge, there are no reports of concurrent mediastinitis with tracheitis in the setting of inflammatory bowel disease. We present a case of a patient with ulcerative proctitis who experienced the development of inflammatory tracheitis and mediastinitis. Her disease responded to systemic steroids and biologic therapy. In addition to our case, we reviewed the literature and provide an approach to pulmonary complications as extra-intestinal manifestation of inflammatory bowel disease.

Abstract
OBJECTIVES Examine the presentation and clinical course of patients with bacterial tracheitis (BT). Identify if socioeconomic differences exist among children who present with BT. METHODS This was a retrospective case series from a tertiary care pediatric medical center. The study group included patients less than 18 years old who were diagnosed with BT from January 2011 to March 2019. Patients with a tracheostomy and those who developed BT after prolonged hospitalization were excluded. Patient demographics were compared with the demographics of the counties surrounding the hospital. RESULTS 33 patients with BT met inclusion criteria. The most common presenting symptoms were difficulty breathing, stridor, and sore throat (81.8% each), followed by cough (78.8%). Median length of stay was 3 days [interquartile range (IQR):2-4]. 19 patients (57.5%) were admitted to the intensive care unit. Intubation was required for 13 patients (39.4%), for a median length of 2 days [IQR:2-2]. Methicillin sensitive staphylococcus aureus was the most common bacterial etiology (33%). Mean presenting age was 8.58 years [95% confidence interval:7.3-9.9] and 14 patients were female (42.4%). 31 patients were white (93.9%), 1 was black (3%), and 1 was Hispanic (3%). BT patients were more likely to have private insurance compared to comparison (81.8% vs 63.4%, P < .001). CONCLUSION Children who presented with BT were more likely to be privately insured than a comparison population.

Abstract
BACKGROUND Pseudomembranous tracheobronchitis (PMTB) is a rare condition characterized by the formation of endobronchial pseudomembranes. PMTB overlaps with necrotizing tracheobronchitis or plastic bronchitis. The reported infectious etiology mainly includes invasive aspergillosis. PMTB can cause serious airway obstruction; however, urgent tracheotomy is rarely required. CASE REPORT A 46-year-old woman was transferred to the emergency department (ED) with a 1-week history of progressive dyspnea and cough that was preceded by fever and sore throat. She was previously healthy except for a 20-year history of mild palmoplantar pustulosis. Stridor was evident. Nasolaryngoscopy performed in the ED revealed severe tracheal stenosis caused primarily by mucosal edema and secondarily by pseudomembranes. Initially, tracheitis was considered the sole cause of dyspnea. Although she underwent urgent tracheotomy to prevent asphyxia, her respiration deteriorated progressively. Bronchoscopy revealed massive pseudomembranes obstructing the bilateral bronchi, which led to the clinical diagnosis of PMTB. Subsequent toilet bronchoscopy markedly improved her ventilation. The causative pathogen was not identified despite extensive work-up, including molecular biological testing. Histopathologic examination of the pseudomembranes revealed fibrin with abundant neutrophils, which was consistent with PMTB. Associated conditions, including immunodeficiency, were not found. Her condition improved with antibiotics and repeated toilet bronchoscopy. WHY SHOULD AN EMERGENCY PHYSICIANS BE AWARE OF THIS?: PMTB is an important differential diagnosis of airway emergencies. PMTB can present with critical edematous tracheal stenosis and masked bronchial pseudomembranous obstruction. Emergency physicians should include PMTB in the differential diagnosis in adult patients with acute central airway obstruction because it requires prompt multimodal treatment.

Abstract
Pseudomembranous tracheitis is a rare life-threatening complication of endotracheal intubation. The exact mechanism of its formation is not well known, and it could mimic crusting or retained secretions in the trachea. We encountered a patient with history of recent intubation, presenting with acute stridor requiring emergency airway stabilization, and was eventually found to have pseudomembranous tracheitis.

Abstract
BACKGROUND When grown in human serum, laboratory isolates of Pseudomonas aeruginosa exhibit tolerance to antibiotics at inhibitory concentrations. This phenomenon, known as serum-associated antibiotic tolerance (SAT), could lead to clinical treatment failure of pseudomonal infections. Our purpose in this study was to determine the prevalence and clinical impact of SAT in Pseudomonas isolates in hospitalized children. METHODS The SAT phenotype was assessed in patients aged <18 years admitted with respiratory or blood cultures positive for P. aeruginosa. The SAT phenotype was a priori defined as a ≥2-log increase in colony-forming units when grown in human serum compared with Luria-Bertani medium in the presence of minocycline or tobramycin. RESULTS SAT was detected in 29 (64%) patients. Fourteen patients each (34%) had cystic fibrosis (CF) and tracheostomies. Patient demographics and comorbidities did not differ by SAT status. Among CF patients, SAT was associated with longer duration of intravenous antibiotics (10 days vs 5 days; P < .01). CONCLUSIONS This study establishes that SAT exists in P. aeruginosa from human serum and may be a novel factor that contributes to differences in clinical outcomes. Future research should investigate the mechanisms that contribute to SAT in order to identify novel targets for adjunctive antimicrobial therapies.

Abstract
OBJECTIVE To review the presentation and treatment of children diagnosed with bacterial tracheitis at our institution and to review the available literature focusing on key presenting symptoms and clinical outcomes of children diagnosed with bacterial tracheitis. STUDY DESIGN Case series with literature review. SETTING Tertiary children's hospital and available literature. SUBJECTS AND METHODS Case series of children with bacterial tracheitis retrospectively reviewed at a tertiary children's hospital. Those with a tracheostomy or those who developed bacterial tracheitis as a complication of prolonged intubation were excluded. RESULTS Thirty-six children were identified (mean ± SD age, 6.7 ± 4.5 years). The most common presenting symptom was cough (85%), followed by stridor (77%) and voice changes/hoarseness (67%). A concurrent viral illness was found for 55%, and the most common bacteria cultured was methicillin-sensitive Staphylococcus aureus. Pediatric intensive care admission occurred for 69%, and 43% required intubation. No patient required tracheostomy. One patient (2.7%) died secondary to airway obstruction and subsequent respiratory arrest. Four patients had recurrence of bacterial tracheitis 4 to 12 months following their initial presentation. CONCLUSION Bacterial tracheitis is an uncommon condition with an atypical presentation and variable clinical course but serious consequences if left unrecognized. Staphylococcus is the most common bacteria identified, and many patients will have a prodromal viral illness. Changes in patient epidemiology and presentation may have occurred over time.

Abstract
OBJECTIVE Identify risk factors for readmission due to a bacterial tracheostomy-associated respiratory tract infection (bTARTI) within 12 months of discharge after tracheotomy. DESIGN/METHODS We performed a retrospective cohort study of 240 children who underwent tracheotomy and were discharged with tracheotsomy in place between January 1, 2005 and June 30, 2013. Children with prolonged total or post-tracheotomy length of stay (LOS), less than 12 months of follow-up, or who died during the index hospitalization were excluded. Readmission for a bTARTI (eg, pneumonia, tracheitis) treated with antibiotics, as ascertained by manual chart review, was the outcome variable. We used multivariate logistic regression to identify the independent association between risk factors and hospital readmission for bTARTI within 12 months. RESULTS At index hospitalizations for tracheotomy, the median admission age was 5 months (interquartile range [IQR] 2-43 months) and median LOS was 73 days (IQR 43-121 days). Most patients were of Hispanic ethnicity (n = 162, 68%) and were publicly insured (n = 213, 89%). Nearly half (n = 112, 47%) were discharged on positive pressure mechanical ventilation. Many (n = 103, 43%) were admitted for bTARTI within 12 months of discharge. Only Hispanic ethnicity (adjusted odds ratio [AOR] 2.0; 95% confidence interval [CI]: 1.1-3.9; P = 0.03) and acquisition of Pseudomonas aeruginosa between tracheotomy and discharge from index hospitalization (AOR 3.2; 95%CI: 1.2-8.3; P = 0.02) were independently associated with increased odds of bTARTI readmission, while discharge on gastrointestinal pro-motility agents was associated with decreased risk (AOR = 0.4; 95%CI: 0.2-0.8; P = 0.01). CONCLUSIONS Hispanic ethnicity and post-tracheotomy acquisition of P. aeruginosa during initial hospitalization are associated with bTARTI readmission.

Abstract
OBJECTIVES Tracheitis is an infection of the lower respiratory tract and is defined by the US Centers for Disease Control and Prevention (CDC) based on signs and symptoms with no radiographic evidence of pneumonia. One method of treatment involves the use of tobramycin given by nebulizer. The purpose of this study was to compare the safety and efficacy of nebulized gentamicin with nebulized tobramycin. METHODS This study was conducted in patients under 21 years of age who received greater than or equal to 1 day of gentamicin, 80 mg, or tobramycin, 300 mg, given twice a day by nebulization within the 14-month study period. The primary endpoint was amount of time until the patient no longer met the CDC definition of tracheitis. RESULTS There were 19 patients who presented with 60 separate encounters. The average age of the patients within the gentamicin group was 7.2 and 5 years old within the tobramycin group. The average duration of time for the gentamicin treatment encounters to be free of the CDC definition of tracheitis was 3.36 days compared to 3.17 days with tobramycin. No adverse effects were observed that were attributable to aminoglycoside nebulization. CONCLUSIONS No differences were detected between the safety and efficacy of intravenous gentamicin administered twice a day by nebulizer and that of tobramycin inhalation solution given twice daily in children without cystic fibrosis.

Abstract
Background Streptococcus salivarius K12 (BLIS K12®) is a probiotic strain producing the bacteriocins salivaricin A2 and salivaricin B, both of which strongly antagonize the growth of Streptococcus pyogenes, the most important bacterial cause of pharyngeal infections in humans. It successfully colonizes and exhibits persistence in the oral cavity and is endowed with an excellent safety profile. Previous observations of a small group of children indicated that the use of BLIS K12 could also reduce the occurrence of viral pharyngitis. The present study focused on a further evaluation of the role of BLIS K12 in the control of pediatric streptococcal disease and moreover whether its use could also help provide protection against various nonstreptococcal infections. Methods In total, 48 children with a recent history of recurrent pharyngeal streptococcal disease were enrolled in the treated group. The control group comprised 76 children known to have had a very low recent occurrence of oral streptococcal disease. The treated children were given BLIS K12 daily for 90 days. The number of episodes of streptococcal pharyngotonsillitis, tracheitis, viral pharyngitis, rhinitis, flu, laryngitis, acute otitis media, enteritis, and stomatitis was recorded during probiotic treatment and for a follow-up period of 9 months, and this was compared with the episodes of the control group over the corresponding period. Results Compared with the pretreatment time period, 2013, a 90% reduction of streptococcal pharyngeal disease was observed in 2014; compared with untreated children, a statistically significant reduction of all of the other disease conditions assessed, other than stomatitis, was detected in the probiotic-treated children. Conclusion In agreement with previous findings, in the present study, it was found that the daily use of BLIS K12 has been associated with a concurrent and persisting reduction in the occurrence of pharyngeal, recurrent, streptococcal disease. Moreover, the benefits to children may also extend to a reduction of nonstreptococcal diseases, including tracheitis, viral pharyngitis, rhinitis, flu, laryngitis, acute otitis media, and enteritis.

Abstract
A 58‐year old lady under active follow‐up with the respiratory services at our institution for bronchiectasis secondary to hypogammaglobulinaemia presented with hoarseness and haemoptysis. She was also receiving rituximab maintenance therapy for follicular lymphoma. Bronchoscopy demonstrated vesicular lesions on her vocal cords and trachea, confirmed as herpes simplex virus (HSV) on cytological analysis of brushings. She responded well to intravenous valacyclovir. Rituximab is increasingly utilised in the treatment of haematological and auto‐immune disorders. This case highlights the potential of this drug to potentiate susceptibility to infection in an already immunocompromised individual.

Acute tracheal oedema and haemorrhage with fibrinonecrotic tracheitis in pigs--a porcine counterpart of bovine honker syndrome? J Comp Pathol 2014; 152:206-10. [PMID: 25435512 DOI: 10.1016/j.jcpa.2014.10.003] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2014] [Revised: 08/26/2014] [Accepted: 10/09/2014] [Indexed: 11/20/2022]
Abstract
Cases of acute tracheal oedema and haemorrhage with fibrinonecrotic tracheitis have been described in Hungarian pig herds. Clinical signs and gross and microscopical tracheal lesions bore resemblance to those of bovine 'honker syndrome'. Diagnostic examination of affected tracheas and corresponding lungs revealed the presence of a variety of agents; however, in some cases tracheal lesions developed without detectable pathogens or associated pulmonary pathology. In line with the bovine condition, this suggests the possibility of cough-induced tracheal damage as an initiating factor for this tracheal change in swine.

Abstract
OBJECTIVE To test the hypothesis that successful implementation of a care bundle designed to prevent nosocomial airway infection will be associated with decreased incidence of ventilator-associated tracheobronchitis. DESIGN Prospective pre- and post interventional. SETTING PICU at an academic medical center PATIENTS : All patients admitted to the PICU who received invasive mechanical ventilation for greater than or equal to 48 hours between March 1, 2009, and December 31, 2011. INTERVENTION Multidisciplinary, unit wide implementation of an evidence-based care bundle to prevent ventilator-associated airway infection. MEASUREMENTS AND MAIN RESULTS There were 725 patients included in the analysis (338 patients preintervention and 387 patients postintervention). Baseline ventilator-associated tracheobronchitis rate in the preintervention period was 3.9 cases per 1,000 ventilator days compared with 1.8 cases per 1,000 ventilator days postintervention (p = 0.04, Fisher exact test). Compared with patients without ventilator-associated tracheobronchitis or ventilator-associated pneumonia, patients with ventilator-associated tracheobronchitis had fewer ventilator-free days in 28 days (4.9 vs 22; p < 0.0001, Mann-Whitney U test) and fewer ICU-free days in 28 days (0.5 vs 19; p < 0.0001, Mann-Whitney U test). These relationships remained significant after adjusting for covariates by multivariable linear regression. CONCLUSIONS Successful implementation of a care bundle to prevent ventilator-associated infection was associated with decreased incidence of ventilator-associated tracheobronchitis. Development of ventilator-associated tracheobronchitis was independently associated with adverse outcomes in our cohort of pediatric ICU patients.

Abstract
Adult croup is a distinct disease entity that probably represents a heterogeneous clinical syndrome. Three cases of adult laryngotracheitis characterized by upper airway infection and progression to airway obstruction are illustrated. Close observation and prompt decisions regarding airway intervention are critical in effective management, and complete resolution is expected.
