Gatt D, Lapidus-Krol E, Chiu PPL. High comorbidity rates in congenital lobar emphysema and the effect on clinical presentation. Eur J Pediatr 2024:10.1007/s00431-024-05684-3. [PMID: 39001901 DOI: 10.1007/s00431-024-05684-3] [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: 04/22/2024] [Revised: 06/26/2024] [Accepted: 07/05/2024] [Indexed: 07/15/2024]
Abstract
The presence of comorbidities (CM) in congenital lobar emphysema (CLE) has been previously described with varying rates. However, the clinical implication of CM on the clinical presentation and patient outcome in CLE is unclear. This was a retrospective cohort study between 2000 and 2022 in a single institution. The study included pediatric patients diagnosed with CLE. During the study period, 36 patients were identified with CLE. The presence of respiratory symptoms at diagnosis was documented in 69% (24/35) of the patients with 48% admitted to intensive care units. The presence of CM was documented in 14/36 (39%) of the patients, with cardiovascular anomalies as the most common (22%), followed by genitourinary anomalies (11%) and large airway anomalies (8%). When comparing the CM group (n = 14) vs the non-CM group (N = 22), there was no significant difference regarding gender, term birth, age of diagnosis, and the location of the lesion. The CM group had significantly higher rates of intensive care unit (ICU) admissions (75% vs 33%, p = 0.02), longer duration of admission (median 46 days vs 9, p = 0.02), and need for pre-operative non-invasive respiratory support (50% vs 5%, p = 0.002).Conclusion: The presence of CM in CLE was associated with a more severe presentation as reflected with significantly higher rates of ICU admissions, prolonged admissions, and higher need for non-invasive respiratory support. Screening for CM, mostly for cardiac anomalies, is recommended at time of CLE diagnosis. What is Known: • Congenital lobar emphysema (CLE) is a developmental lung anomaly generally associated with other comorbidities; however, their clinical implication on presentation is unclear • The prevalence of comorbidities in CLE was previously reported around 15-20%, with cardiovascular anomalies as the most common What is New: • Comorbidities are very common (39%) in CLE, and their presence is related to a more severe clinical presentation and need for respiratory support • Screening for comorbidities is recommended in CLE, specifically for cardiovascular and genitourinary anomalies.

Abstract
Recurrent wheezing is very common in infants. When these symptoms appear early without a free interval, a pulmonary malformation should be investigated. Congenital lobar emphysema is a rare abnormality of the lower respiratory tract. Here, we report a case series of six cases of congenital lobar emphysema between 2015 and 2023. Clinical and radiological data were collected according to an operating sheet previously established in our pediatric pneumo-allergology unit. They all had recurrent wheezing and dyspnea. Chest radiography and chest CT were consistent with the diagnosis of congenital lobar emphysema. All patients had lobectomy without complications.

Abstract
Congenital lobar emphysema (CLE) is a rare developmental malformation that presents as neonatal respiratory distress and can be successfully managed with prompt intervention. Hyperinflation of the affected lobe with mediastinal shift is the characteristic radiological finding. However, the etiology mostly remains unknown. Here, we report a case of CLE that microscopically revealed bronchial cartilaginous hypoplasia as an underlying cause of this malformation.

Abstract
INTRODUCTION Surgical (OP) management for symptomatic congenital lobar emphysema (CLE) is the standard of care with nonoperative (NOP) approach applied for asymptomatic cases. The aim of this study is to report the outcomes for NOP approach to the care of symptomatic CLE infants. METHODS A retrospective study of CLE patients treated 2000-2021 at a single institution. Patients with CLE and respiratory symptoms were included. RESULTS Overall, 23 children had symptomatic CLE, and 12 had NOP management. The median age at diagnosis was 38.5 days (50) in the NOP group versus 25 days (20) in the OP group (p = 0.31). There was no significant difference in the location of the involved lobe, term birth, postnatal diagnosis and gender, and both groups required noninvasive support in 33% of the cases. There was a trend towards higher frequency of oxygen support in the OP group preoperatively (89% vs. 42%, p = 0.07). The median length of stay was 14 days in the NOP group compared to a median postsurgery stay of 7.5 days in the OP group. In follow-up, there was no significant difference in respiratory readmission in first year of life, growth delay, treatment with asthma medication or body mass index in the NOP versus OP group. None of the children in the NOP group required surgery during follow-up. CONCLUSIONS A NOP approach for symptomatic CLE infants can have favorable long-term outcomes. Further studies will be required to identify markers to aid in clinical decision-making.

Abstract
Congenital lobar emphysema (CLE) is caused by airway defects resulting in air trapping and hyperinflation of the affected lobe. Case reports of families affected with CLE imply a genetic etiology. However, the genetic contributions have not been well-described. We present a case of CLE in a monozygotic twin brother with respiratory distress diagnosed with right upper lobe (RUL) CLE and treated with a lobectomy. His asymptomatic twin brother was screened prophylactically, found to have RUL CLE and subsequently underwent a lobectomy. Our report provides further evidence supporting the genetic predisposition and potential benefit of early screening for CLE in comparable scenarios.

Surgery versus conservative management in congenital lobar emphysema: follow up and indicators for surgery. Pediatr Surg Int 2022; 38:559-568.

Abstract
INTRODUCTION Congenital lobar emphysema (CLE), a rare developmental lung malformation, involves the hyperaeration of one or more lung lobes caused by partial obstruction and occurs at a rate of 1/20,000-30,000 live births. Here, we aimed to retrospectively examine the clinical, radiological, and bronchoscopy findings of patients with CLE who were diagnosed and treated by surgical or non-surgical (conservative) approaches at our center and compared our results with those in the literature. METHODS We examined the clinical, radiological, and bronchoscopy findings of 20 patients with CLE aged 0-18 years at our center between 2013 and 2020. In addition, we examined the symptoms and findings recorded during the patients' follow-up in this retrospective descriptive study. RESULTS The median age of 20 patients with CLE at diagnosis was 3.2 years (range 1 day-17 years). Respiratory distress and mediastinal shift were more prominent in patients who underwent surgery, and they were diagnosed at an earlier age compared with patients who were followed up conservatively (p = 0.001, 0.049, 0.001, respectively). Neither the pulmonary lobe involvement nor the bronchoscopy findings were found to be indicative of surgery. DISCUSSION We observed that respiratory distress and mediastinal shift were more prominent in patients with a diagnosis of CLE who underwent surgery compared with patients who were conservatively followed up. Moreover, we observed that those who underwent surgery were diagnosed with CLE at an earlier age. In line with the literature, the pulmonary symptoms and CLE-related imaging findings in our study were reduced during conservative follow-up.

Abstract
Congenital lung malformations are a spectrum of developmental anomalies comprised of malformations of the lung parenchyma, airways, and vasculature. Imaging assessment plays a pivotal role in the initial diagnosis, management, and follow-up evaluation of congenital lung malformations in the pediatric population. However, there is currently a lack of practical imaging guidelines and recommendations for the diagnostic imaging assessment of congenital lung malformations in infants and children. This article reviews the current evidence regarding the imaging evaluation of congenital lung malformations and provides up-to-date imaging recommendations for pediatric congenital lung malformations.
