Background:Interstitial lung disease (ILD) in inflammatory rheumatic diseases (IRD) is associated with increased mortality. Moreover, the lung is one of the most effected organs on IRD. Consequently, screening methods were required to the detect ILD in IRD.Objectives:The objective of the following study is to evaluate the diagnostic value of lung function test, chest x-ray and HR-CT of the lung in the detection of ILD at the onset of IRD.Methods:The study is designed as a case-control study and includes 126 patients with a newly diagnosed IRD. It was matched by gender, age and the performance of lung function test and chest x-ray. The sensitivity and specificity were verified by crosstabs and receiver operating characteristic (ROC) curve analysis. The study cohort was divided in two groups (ILD group: n = 63 and control group: n = 63). If possible, all patients received a lung function test and optional a chest x-ray. Patients with pathological findings in the screening tests (chest x-ray or reduced diffusing capacity for carbon monoxide (DLCO) < 80 %) maintained a high-resolution computer tomography (HR-CT) of the lung. Additionally, an immunological bronchioalveolar lavage was performed in the ILD group as gold standard for the detection of ILD.Results:The DLCO (< 80 %) revealed a sensitivity of 83.6 % and specificity of 45.8 % for the detection of ILD. Other examined parameter of lung function test showed no sufficient sensitivity as screening test (FVC = Forced Vital Capacity, FEV1 = Forced Expiratory Volume in 1 second, TLC = Total Lung Capacity, TLCO = Transfer factor of the Lung for carbon monoxide). Also, a combination of different parameter did not increase the sensitivity. The sensitivity and specificity of chest x-ray for the verification of ILD was 64.2 % versus 73.6 %. The combination of DLCO (< 80 %) and chest x-ray showed a sensitivity with 95.2 % and specificity with 38.7 %. The highest sensitivity (95.2 %) and specificity (77.4 %) was observed for the combination of DLCO (< 80 %) and HR-CT of the lung.Conclusion:The study highlighted that a reduced DLCO in lung function test is associated with a lung involvement in IRD. DLCO represented a potential screening parameter for lung manifestation in IRD. Especially patients with suspected vasculitis should receive an additional chest x-ray. Based on the high sensitivity of DLCO in combination with chest x-ray or HR-CT for the detection of ILD in IRD, all patients with a reduced DLCO (< 80%) should obtained an imaging of the lung.Disclosure of Interests:None declared

Penehyclidine Hydrochloride

Purpose: We analyze chest X-ray diagnosis results of patients undergoing cardiopulmonary bypass heart surgery in intensive care unit (ICU). In our previous study, we found that penehyclidine hydrochloride (PHC) preconditioning pretects lung function and reduced the apoptosis. Although preconditioning is effective, this clinical treatment is often given only when symptoms appear, when postconditioning is easier to administer. In this study, after confirming the lung condition via medical image analysis, we aimed to look the effect of high-dose penehyclidine hydrochloride postconditioning in lung after I/R in rats, and the apoptosis mechanisms involved. Methods: Chest X-ray was taken in 256 adult patients under cardiopulmonary bypass with heart syurery. Medical image analysis was preliminarily performed, the diagnostic results were analyzed. Rats were subjected to ischemia in left lung 45 min, and then 2 h reperfusion, and treated with PHC. We then observed the effects of PHC on the following: lung function, lung injury, oxidative stress, rate of apoptosis of lung cells, apoptosis-related proteins, and the p38 MAPK pathway. Results: Analysis results of chest X-ray suggest multiple pulmonary complications after cardiopulmonary bypass heart surgery. The laboratory results showed that high-dose penehyclidine hydrochloride postconditioning significantly protected lung function, reduced oxidative stress and apoptosis of the lungs caused by reperfusion, and inhibited activation of the p38 MAPK pathway. Conclusion: Analysis results of chest X-ray show multiple pulmonary complications after cardiopulmonary bypass heart surgery. This study suggests that high-dose penehyclidine hydrochloride can treat lung I/R injury.

Background A remarkable relationship between upper airway conditions and lung diseases has been reported. At the same time, sinonasal findings in chronic cough patients have not been fully examined. Objective The purpose of this study is to show paranasal sinus findings and lung function in chronic cough patients without asthma and chest X-ray abnormalities. Methods A total of 1412 patients with persistent cough were enrolled in this study. Of these patients, 376 patients were evaluated for further examination, as the patients with asthma and/or chest X-ray abnormality were excluded from the study. Normal control subjects without any chronic respiratory symptoms were also recruited. Pulmonary function was examined by spirometry. A bronchial obstruction reversibility test was applied. The Lund–Mackay computed tomography (CT) score, peripheral blood eosinophil count, and immunoglobulin E concentration in serum samples were examined. The Sino-Nasal Outcome Test was used to determine the severity of clinical symptoms. Results The patients with an abnormal soft tissue shadow in the paranasal sinus had significant obstructive lung function. The percent predicted forced expiratory volume in 1 second (FEV1.0) and the FEV1.0/forced vital capacity ratio negatively correlated with Lund–Mackay CT scores both before and after bronchodilator inhalation. There was a statistically significant correlation between pulmonary function and eosinophil count. Conclusion The patients with chronic cough frequently had paranasal sinus abnormalities. The Lund–Mackay CT score may be useful for assessing the condition of the lower airway in chronic cough patients. Upper airway examinations should play a part in the management of chronic cough.

In this review, we argue for the use of high-resolution computed tomography (HRCT) over chest X-ray in the initial evaluation of patients with sarcoidosis. Chest X-ray, which has long been used to classify disease severity and offer prognostication in sarcoidosis, has clear limitations compared with HRCT, including wider interobserver variability, a looser association with lung function, and poorer sensitivity to detect important lung manifestations of sarcoidosis. In addition, HRCT offers a diagnostic advantage, as it better depicts targets for biopsy, such as mediastinal/hilar lymphadenopathy and focal parenchymal disease. Newer data suggest that specific HRCT findings may be associated with important prognostic outcomes, such as increased mortality. As we elaborate in this update, we strongly recommend the use of HRCT in the initial evaluation of the patient with sarcoidosis.

End Stage

Emphysematous bullae are a complication of end-stage COPD. Patients with large bullae and poor respiratory function have limited treatment options. Surgical resection is a recognized treatment, but functional improvement after bullectomy is not satisfactory in patients with forced expiratory volume in 1 s (FEV1) < 35% predicted. When this 59-year-old male end-stage COPD patient was assessed, he was cachectic and lung function tests showed a FEV1 of 0.56 L (19% predicted) and a RV of 7 L (314% predicted), while 6MWT was 315 m and MRC dyspnea score was 4. Chest X-ray revealed a massive bulla of 10 cm in diameter in the right middle lobe. A fibrobronchoscopy was performed under local anesthesia and 2 Zephyr 4.0 valves were placed in the right middle lobe. Chest X-ray and CT scan performed 36 days later showed the complete resolution of the bulla. Seven months later, the patient demonstrated an improvement in FEV1 (+30%) and a decrease in RV from 314 to 262% predicted. This case report shows that the Zephyr valves may be successfully used to treat a large bulla in the right middle lobe in a patient with diffuse emphysema and severely impaired lung function.
