We present a 70-year-old gentleman with chronic cough with haemoptysis found to have left lower zone collapse on imaging. The bronchoscopy showed an endobronchial mass histologically of a non-secreting atypical carcinoid. Poor baseline lung function excluded surgical resection, and instead, he successfully underwent a bronchoscopic debulking procedure which improved his FEV1 to 84% and DLCO 83% predicted. Unfortunately, the tumour regrew, but the calculated percentage predicted postoperative for FEV1 (64%), and DLCO (65%) enabled definitive surgical resection to take place. Surgical resection remains the definite curative option for localised endobronchial atypical carcinoid tumours. Achieving this in proximal endobronchial carcinoid tumour is a challenge. We described an endoscopic tumour debulking procedure as a bridge for curative surgical resection in a patient with an inoperable proximal atypical carcinoid tumour due to poor predicted postoperative lung function. We highlighted the need to assess predicted postoperative lung function with functional and quantitative perfusion methods to aid surgical planning. Debulking the tumour by endoscopy can be used as a conduit to curative surgical resection in bronchial carcinoid tumour. The choice of calculating the percentage predicted values by either or both methods must be individualised based on tumour location and the probability of converting a lobectomy to a pneumonectomy. This precautionary approach could evaluate the postoperative lung function and morbidity and mortality risk if considering a pneumonectomy. Endoscopic debulking can be a successful bridge to a curative surgical resection aided by comprehensive preoperative lung function tests to predict postoperative lung values

AbstractThe case of an atypical carcinoid tumour of the larynx is described in a 65-year-old man. Thisrare tumour may present diagnostic difficulties, but the diagnosis should be considered in a patient presenting with symptoms of local or referred pain and an apparently small, non-ulcerating supraglottic tumour. Immunocytochemistry has an important role in establishing the diagnosis. A very unusual feature of this case was positive staining for S-100 protein by sustentacular cells. Atypical carcinoid tumours do not respond well to radiotherapy so the primary treatment should be surgical resection.

Abstract Background/Aims  Intravenous immunoglobulin (IVIg) confers significant benefit in range of connective tissue diseases (CTD) including inflammatory myopathy (IM) of which interstitial lung diseases (ILD) are a major complication. This study aimed to assess the efficacy of IVIg on pulmonary involvement in refractory active CTD including systemic sclerosis (SSc). Methods  All patients with CTD-ILD confirmed on HRCT either with IM or SSc overlap myositis who did not achieve satisfactory clinical response to standard immunosuppressive agents and subsequently received regular IVIg infusions for IM were retrospectively identified. Serial lung function tests and immunosuppressive treatment regimen 9-12 months prior and 9-12 months after repeat courses of IVIg were recorded. Progressive ILD was considered when, despite immunosuppressive treatment, a relative FVC decline≥10% and/or relative DLco decline ≥15% were identified during the 9-12 months preceding IVIg treatment. The significance of median DLco and FVC percentage relative change to IVIg treatment was assessed by Wilcoxon signed-rank test. Results  22 patients (mean age 50.5±13.1 years old) with IM-ILD treated with IVIg were identified. ILD occurred in association with IM in 10 patients, overlap SSc myositis in another 11 patients, while one had mixed connective tissue disease with myositis. Lung function results were available for 19/22 (86%). Eight patients (42.1%) were found to have progressive ILD(four with IM and four with overlap SSc-myositis). The median change in FVC% predicted and DLco% predicted in the 9-12 months before and after IVIg treatment is presented in Table 1. There was a significant difference in the DLco% predicted rate of relative change before and after IVIg treatment (p = 0.035) for the overall cohort. However, no differences in lung function were observed in the rate of relative change between patients with IM and patients with SSc myositis overlap. Significant improvement in DLco% predicted values was identified in the subgroup analysis of patients with progressive ILD(p = 0.012).

Future studies to determine its role in CTD-ILD are warranted. Disclosure  V. Kouranos: None. L.V. Host: None. C. Campochiaro: None. A. Wells: None. C.P. Denton: None. V.H. Ong: None. E.

Background: Asthma may show an accelerated lung function decline. Asthmatics, although having FEV1 and FEV1/VC (and z-scores) higher than the lower limit of normality, may show a significant FEV1 decline when compared to previous measurements. We assessed how many asymptomatic long-standing asthmatics (LSA) with normal lung function showed a significant FEV1 decline when an older FEV1 was taken as reference point. Methods: 46 well-controlled LSA (age: 48.8±12.1; 23 females) with normal FEV1 and FEV1/VC according to GLI2012 references (FEV1: 94.8±10.1%, z-score:-0.38±0.79; FEV1/VC: 79.3±5.2, z-score:-0.15±0.77) were selected. We considered FEV1 decline, calculated by comparing the latest value to one at least five years older or to the highest predicted value measured at 21 years for females and 23 for males. A FEV1 decline >15% or 30 ml/years was regarded as pathological. Results: When comparing the latest FEV1 to an at least 5-year-older one (mean 8.1±1.4 years between 2 measurements), 14 subjects (30.4%) showed a FEV1 decline <5% (mean: -2.2±2.6%), 19 (41.3%) had a FEV1 5-15% change (mean: -9.2±2.5%) and 13 (28.3%) a FEV1 decrease>15% (mean: -18.3±2.4). Subjects with a FEV1 decline>30 ml/year were 28 (60.8%). When using the highest predicted FEV1 as reference point and declines were corrected by subtracting the physiological decrease, 6 (13%) patients showed a FEV1 decline higher than 15%, whereas asthmatics with a FEV1 loss>30 ml/year were 17 (37%). Conclusion: FEV1 decline calculation may show how severe asthma actually is, avoiding a bronchial obstruction underestimation and a possible under-treatment in lots of apparent “well-controlled” LSA with GLI2012-normal-range lung function values.

Eosinophil Counts

Eosinophilic inflammation and airway remodelling are characteristic features of asthma, but the association between them is unclear. We assessed associations between blood eosinophils and lung function decline in a population-based cohort of young adults.We used linear mixed models to analyse associations between blood eosinophils and spirometry at 21, 26, 32 and 38 years adjusting for sex, smoking, asthma and spirometry at age 18 years. We further analysed associations between mean eosinophil counts and changes in spirometry from ages 21 to 38 years.Higher eosinophils were associated with lower forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC) ratios and lower FEV1 % predicted values for both pre- and post-bronchodilator spirometry (all p-values ≤0.048). Although eosinophil counts were higher in participants with asthma, the associations between eosinophils and spirometry were similar among participants without asthma or wheeze. Participants with mean eosinophil counts >0.4×109 cells·L−1 between 21 and 38 years had greater declines in FEV1/FVC ratios (difference 1.8%, 95% CI 0.7–2.9%; p=0.001) and FEV1 values (difference 3.4% pred, 95% CI 1.5–5.4% pred); p=0.001) than those with lower counts.Blood eosinophils are associated with airflow obstruction and enhanced decline in lung function, independently of asthma and smoking. Eosinophilia is a risk factor for airflow obstruction even in those without symptoms.

Postoperative Lung Function

The assessment of patients likely to undergo lung resection surgery is a multidisciplinary approach involving pulmonologists, surgeons and anaesthesiologists. In thoracic surgery, medical operability is also a calculation of postoperative lung function. A mobile application – PreParAPP MSD – to calculate postoperative lung function has been developed with the endorsement of the Italian Society of Anaesthesia, Analgesia and Intensive Care and with the unconditional support of MSD Italia. Thanks to a simple graphic interface, the calculation becomes fast and intuitive, while the possibility of storing and sharing data in an analytical and computerised way with other clinicians might help with the full assessment of patients without forcing them to undergo several medical examinations. These simple calculated parameters are performed by a minority of clinicians, generally anaesthesiologists. In our facility, there is a team involved in the perioperative evaluation of lung resection surgery (13 pulmonologists, 9 surgeons and 5 anaesthesiologists). In order to evaluate the possible Awareness towards postoperative lung function calculation better, we organised an internal survey with 27 clinicians who are members of such a team before and after the introduction of the PreParAPP MSD. It was found that after the introduction of PreParAPP MSD, the percentage of clinicians involved in postoperative lung function calculation rose from 18% to 70%. The implementation of a digital tool may help to improve guideline adherence, in accordance with other experiences in which such tools represented the start for various quality improvement purposes throughout the medical field.
