Tracheobronchial Foreign Body

Background: Tracheobronchial foreign body aspiration (TFBA) is a major cause of death in children. There are few reports about lower respiratory tract infection (LRTI) caused by TFBA. This study collected the TFBA in our hospital to analyze the LRTI and to determine its risk factors. Methods: A total of 194 children who were performed TFBA extraction in The Children’s Hospital of Zhejiang University School of Medicine between June 2019 and April 2020 were enrolled. The clinical data, cervicothoracic CT and operation records were collected. Chi-square test, rank sum test and multivariate logistics regression analysis were applied. Results: The incidence of LRTI was 46.6%, 68.6% and 68.6% respectively when retention time was within 24 hours, 1 week and more than 1 week. Cervicothoracic CT showed embedding site in and above trachea in 24 cases, in main bronchus in 134 cases, in segmental bronchus and below in 36 cases. Cervicothoracic CT showed no obvious abnormality in 60 cases, obstructive emphysema or atelectasis in 77 cases, obstructive pneumonia in 50 cases, and the rest in 7 cases. Cervicothoracic CT diagnosis and retention time of TFBA were different between LRTI group and non-LRTI group in univariate analysis. There was a correlation between the retention time of TFBA and LRTI in multivariate logistics regression analysis. Conclusionss: The incidence of LRTI caused by TFBA is high. There was no difference in the incidence of LRTI between organic and inorganic TFBA. The retention time of TFBA is an independent risk factor for LRTI.

Abstract Data are limited regarding risk factors for lower respiratory tract infection (LRTI) caused by seasonal human coronaviruses (HCoVs) and the significance of virologic documentation by bronchoalveolar lavage (BAL) on outcomes in hematopoietic cell transplant (HCT) recipients. We retrospectively analyzed patients undergoing allogeneic HCT (4/2008-9/2018) with HCoV (OC43/NL63/HKU1/229E) detected by polymerase chain reaction during conditioning or post-HCT. Risk factors for all manifestations of LRTI and progression to LRTI among those presenting with HCoV upper respiratory tract infection (URTI) were analyzed by logistic regression and Cox proportional hazard models, respectively. Mortality rates following HCoV LRTI were compared according to virologic documentation by BAL. A total of 297 patients (61 children and 236 adults) developed HCoV infection as follows: 254 had URTI alone, 18 presented with LRTI, and 25 progressed from URTI to LRTI (median, 16 days; range, 2-62 days). Multivariable logistic regression analyses showed that male sex, higher immunodeficiency scoring index, albumin <3 g/dL, glucose >150 mg/dL, and presence of respiratory copathogens were associated with occurrence of LRTI. Hyperglycemia with steroid use was associated with progression to LRTI (P < .01) in Cox models. LRTI with HCoV detected in BAL was associated with higher mortality than LRTI without documented detection in BAL (P < .01). In conclusion, we identified factors associated with HCoV LRTI, some of which are less commonly appreciated to be risk factors for LRTI with other respiratory viruses in HCT recipients. The association of hyperglycemia with LRTI might provide an intervention opportunity to reduce the risk of LRTI.

Background: Moraxella catarrhalis is a Gram-negative diplococcus, commonly found as a normal flora in the human upper respiratory tract. Recently, M. catarrhalis has emerged as an important and common human respiratory tract pathogen. This study was aimed to determine the rate of isolation of M. Catarrhalis in patients attending a tertiary care hospital with lower respiratory tract infection (LRTI), antibiotic susceptibility pattern and predisposing factors responsible for their infection.Methods: A prospective study was carried out in 1001 lower respiratory specimens from patients (above 20 years’ age) with suspected LRTI.  The study investigated by microscopic examination, culture and antibiotic sensitivity test according to the standard guidelines. Assessment of clinical significance of M. Catarrhalis was ascertained on the basis of preformed criteria.Results: A total of 60 clinically significant M. Catarrhalis were isolated from the 930 culture positive samples. The isolates showed maximum sensitivity to second and third generation cephalosporins (95%), azithromycin (90%) followed by amoxicillin clavulanic acid (85%). Rate of isolation was more in males (70%) and elderly people above 60 years (63.33%) were found to be more affected. Patients (58.33%) with Chronic Obstructive Pulmonary Diseases (COPD) were found to be more prone to get infection by M. Catarrhalis.Conclusions: Moraxella catarrhalis should be considered as significant lower respiratory tract pathogen especially in elderly patients with underlying risk factors like COPD.
