A new Editorial Board of Monaldi Archives for Chest Disease

In recent years, Monaldi has reached a widespread diffusion and consolidated its reputation as a good quality scientific journal in the field of cardiopulmonary rehabilitation. Many of these achievements are due to the hard work of many pulmonary physicians, most of them, including the last two former Editors, Claudio F. Donner and Ciro Rampulla, part of the FSM and distinguished leaders of research groups in their field. Commercing in 2002, Monaldi has divided the published issues in a Cardiologic and in a Pulmonary Series, issued separately. This year, FSM decided to renew also the Editorial Board of the Pulmonary series. Beginning with the present issue we (Antonio Spanevello and Bruno Balbi) are the two new Co-Editors. We are currently Head and Scientific Secretary, respectively, of the Pulmonary Rehabilitation Department, the organization that comprises the Pulmonary Physicians working at FSM. As Editors we will work together with two Deputy Editors (Dr. Mirco Lusuardi, Head of Pulmonary Rehabilitation, Health Authority of Reggio Emilia and Dr. Maurizio Luisetti, Head of Biochemistry and Genetics in Pulmonary Medicine, University of Pavia) and two Executive Editors (Dr. Giuseppe Brunetti and Dr. Luca Bianchi, both at FSM). This \u201cunder fifty\u201d Editorial Board, is deeply committed to doing the best for our Journal and to continue and extend the precious work done by the previous Editors. We heritage a healthy and well-nourished scientific journal. It is an honor and a privilege to take over as Editors from Ciro Rampulla and we thank him for his wise and culturally rich contribution to Monaldi. As Editor in Chief of the past Editorial Board in the last 2 years Ciro worked hard and refined the editorial and administrative procedures, with the full support of the FSM. His example will be a guide for us to chair the Editorial Board of the Journal

Bronchoalveolar lavage causes decrease in PaO2, increase in (A-a) gradient value and bronchoconstriction in asthmatics.

7siAbstract The aims of this study were to (1) record the changes of (arterial oxygen partial pressure) PaO2, (arterial carbon dioxide partial pressure) PaCO2, (percentage saturation of haemoglobin with oxygen in arterial blood) SaO2 and alveolar-arterial (A-a) oxygen gradiant resulting from bronchoalveolar lavage (BAL) in asthmatic and normal subjects; (2) measure changes in forced expiratory volume in 1 s (FEV1), vital capacity forced (FVC) associated with BAL; and (3) assess possible predictive factors for the degree of hypoxaemia and impairment of spirometry resulting from BAL. Bronchoscopy and BAL (150 ml) were performed in 24 asthmatics and 15 healthy subjects. Serial arterial blood samples (radial artery) were obtained in all subjects: T1 and before T2 after local anaesthesia; T3 at end of bronchoscopy; T4 after BAL and 5 min, 15 min, 1 h, 2 h, 8 h and 24 h (T5-T10) after the procedure, FEV1 and FVC were measured immediately before and 5 min afer bronchoscopy. Baseline PaO2 was lower in asthmatics (10.2 +/- 0.8 kPa) than in healthy subjects (10.8 +/- 0.8). Both groups showed a significant decrease in PaO2, and a significant widening in (A-a) oxygen tension gradiant at T3-9, with respect to T1 (P < 0.05). PaO2 reached a significantly lower value in asthmatics (7.1 +/- 0.6 kPa) than in HS (7.7 +/- 0.5; P < 0.05). In asthmatics, FEV1, FVC and the ratio FEV1/FVC decreased significantly after BAL (P < 0.001). In healthy subjects, FEV1 and FVC decreased significantly (P < 0.001), whereas FEV1/FVC did not. The fall in FEV1 after BAL was significantly greater in asthmatics (32.4 +/- 10.0%) than in healthy subjects (17.7 +/- 4.6; P < 0.001). Severity of asthma, basline FEV1 or initial PaO2 did not predict the degree of hypoxaemia or the fall of FEV1. It is concluded that BAL causes more severe hypoxaemia and a greater decrease in FEV1 in asthmatics compared to healthy subjects, strongly supporting the recommendation of special caution and careful monitoring when BAL is undertaken in asthmatics.nonemixedSPANEVELLO A; MIGLIORI GB; SATTA A; SHARARA A; BALLARDINI L; IND PW; NERI M.Spanevello, Antonio; Migliori, Gb; Satta, A; Sharara, A; Ballardini, L; Ind, Pw; Neri, M

Comparison of two methods of processing induced sputum: selected versus entire sputum.

Abstract Sputum analysis is increasingly used to assess airway inflammation in asthma. The analysis of sputum is currently performed with two techniques, i.e., analysis of selected sputum (plugs) and analysis of entire sputum. To investigate the diagnostic value of these two methods, we compared total and differential cell counts and supernatant eosinophil cationic protein (ECP) in selected and entire sputum collected on two occasions in a group of healthy and asthmatic subjects. We induced sputum with hypertonic saline in 18 asthmatics and in eight healthy subjects. On one occasion we analyzed selected sputum, and on another occasion we analyzed entire sputum. In each sample we measured total and differential cell counts and ECP concentration in supernatant. We found a higher percentage of eosinophils (15.3 versus 8.3%; p < 0.01), more viable nonsquamous cells (80.6 versus 71.8%; p < 0.01), and higher levels of ECP (548 versus 105 microg/L; p < 0.001) in selected sputum as compared with entire sputum, whereas the percentage of neutrophils was higher in the entire sputum (42.7 versus 33.3%; p < 0.05). The percentage of eosinophils and ECP concentration were significantly and similarly increased in both selected and entire sputum of asthmatic subjects, i.e., independent of the method of sputum analysis. In conclusion, the selected sputum method may indeed provide more viable cells, more eosinophils, and a higher concentration of ECP. However, both the selected sputum and the entire sputum method have the same diagnostic value in distinguishing asthmatics from healthy subjects

Fibre types in skeletal muscles of chronic obstructive pulmonary disease patients related to respiratory function and exercise tolerance.

Abstract This study aimed to investigate the relationship between skeletal muscle, fibre type composition, functional respiratory impairment and exercise tolerance in patients with moderate to severe chronic obstructive pulmonary disease (COPD). A group of 22 COPD patients and 10 healthy control subjects were studied. In COPD patients, vital capacity (VC) and forced expiratory volume in one second (FEV1) were reduced to 79% and 51%, respectively. Diffusion indices (transfer factor of the lung for carbon monoxide (TL,CO) and carbon monoxide transfer coefficient (KCO)) were also reduced. Arterial oxygen tension (Pa,O2) was normal or slightly altered. A maximal exercise test was performed and anaerobic threshold was calculated. Muscle samples from vastus lateralis were obtained by needle biopsy. Myosin heavy chain (MHC) and light chain (MLC) isoforms were separated by gel electrophoresis and quantified by densitometry. MHC isoforms were considered as molecular markers of fibre types. The proportion of the fast MHC-2B isoform was increased in COPD patients. TL,CO, KCO, VC and FEV1 were positively correlated with slow MHC isoform content. TL,CO and KCO were also negatively correlated with the content of the fast MHC-2B isoform. No correlation was found between exercise parameters and MHC isoform composition. The co-ordinated expression between MHC and MLC isoforms was altered in COPD patients. We conclude that reduced oxygen availability, probably in combination with muscle disuse, may determine muscle alterations in chronic obstructive pulmonary disease patients. The altered correlations between myosin heavy chain and light chain isoforms suggest that co-ordinated protein expression is lost in chronic obstructive pulmonary disease muscles

Induced sputum cellularity. Reference values and distribution in normal volunteers.

Abstract Sputum induction has recently been proposed as the only direct noninvasive method for measuring airway inflammatory indices. The reference values and the distribution of cells in induced sputum in a control population have not yet been well defined. We therefore evaluated data from a large number of healthy volunteers. One hundred fourteen healthy, nonatopic, nonsmoking volunteers without airway hyperreactivity were enrolled (age: 38 +/- 13 yr [mean +/- SD]; FEV(1): 105 +/- 10% predicted; provocative dose of methacholine inducing a 20% decrease FEV(1) > 3,200 microgram). Ninety-six subjects (84%) produced adequate analysis samples. The subjects had a normal age distribution. Their induced sputum was rich in macrophages (69.2 +/- 13%) and neutrophils (27.3 +/- 13%), and poor in eosinophils (0.6 +/- 0.8%), lymphocytes (1.0 +/- 1.2%), and epithelial cells (1.5 +/- 1.8%). Only macrophages and neutrophils showed a normal distribution; total and differential counts of other cells did not. We propose that these data be used in comparison of the induced sputum cells of normal subjects and those of patients with airway inflammation

Induced sputum in the management of COPD: clinical implications

Sputum induction can be used as a non-invasive technique to investigate airway inflammation in asthma and COPD. We reported the case of a 68 year old man with COPD, stage III GOLD, that underwent sputum induction during two exacerbation episodes. The first cell count showed a typical sputum neutrophilia, whereas the second showed sputum eosinophilia. On the basis of sputum cellularity, we decided to treat the first episode with a course of antibiotics and the second exacerbation with a course of antibiotics and oral steroids. The patient showed improvement in both cases, obtaining clinical stabilisation. The induced sputum cell count could be a useful technique in a clinical setting to evaluate the cellular characteristics of airway inflammation during COPD exacerbation and modulate the antinflammatory therapy
