Hypersensitivity pneumonitis : Lessons from a randomized controlled trial in children
2021
Introduction Hypersensitivity pneumonitis (HP) in children is a severe interstitial lung disease and potentially, a chronic condition, if not treated appropriately. No evidence-based guidelines are available; in particular, the role of systemic glucocorticoid therapy is unclear. Methods The aim of this randomized, double-blind, placebo-controlled, parallel-group, multi-center, phase II trial in pediatric HP was to assess the outcome of HP in children after 6 months of treatment and to compare 3 months of treatment with oral prednisolone or placebo. Results After 1.5 years and the inclusion of only four children, we terminated the study prematurely. Two of the children randomized to predniso…
Retrograde in situ versus antegrade pulmonary preservation in clinical lung transplantation: a single-centre experience.
2014
OBJECTIVE Experimental and clinical studies have indicated a beneficial effect of retrograde lung preservation on post-transplant results. Accordingly, we conducted a non-randomized trial. METHODS A total of 209 consecutive recipients transplanted with low-potassium dextrane (LPD)-preserved lungs were eligible for analysis. Antegrade lung preservation (AP) was performed in 173 patients and retrograde in situ perfusion (RP) in 36 patients using low-potassium dextrane solution in all cases. The prostacycline was added to preservation solution. RESULTS The main donor, graft and recipient characteristics did not differ significantly between groups. There was a beneficial trend toward improved o…
Bidirectional Glenn and antegrade pulmonary blood flow: temporary or definitive palliation?
2008
Background We sought to investigate the role of the bidirectional Glenn with antegrade pulmonary blood flow in the surgical history of children with univentricular hearts. Methods A series of 246 patients, from three joint institutions, having univentricular heart with restricted but not critical pulmonary blood flow received a bidirectional cavopulmonary shunt with additional forward pulmonary blood flow. All patients have been studied according to their progression, or not, to Fontan operation. Two hundred and eight (84.5%) patients underwent bidirectional cavopulmonary anastomosis as primary palliation. Twenty patients (8.1%) with previous pulmonary artery banding were also enrolled in t…
DOES LEPTIN PLAY A CYTOKINE-LIKE ROLE WITHIN THE AIRWAYS OF COPD PATIENTS?
2005
The leptin-leptin receptor system might be up-regulated in the airways of chronic obstructive pulmonary disease (COPD). In bronchial biopsies obtained from normal subjects and smokers, with and without COPD, the present study examined leptin and leptin-receptor expression and their co-localisation in airway and inflammatory cells. Combining immunohistochemistry with terminal deoxynucleotidyl transferase dUTP nick end-labelling techniques, apoptosis in airway and inflammatory cells and in leptin and leptin-receptor expressing cells was investigated. In the epithelial cells both leptin and leptin-receptor expression was higher in normal subjects than in smokers and COPD subjects. By contrast,…
Gemcitabine and cisplatin versus vinorelbine and cisplatin versus ifosfamide+gemcitabine followed by vinorelbine and cisplatin versus vinorelbine and…
2003
Abstract Purpose: we carried out a phase III randomized trial to compare vinorelbine–cisplatin regimen to gemcitabine–cisplatin regimen, and to a sequential administration of gemcitabine–ifosfamide followed by vinorelbine–cisplatin or the opposite sequence of vinorelbine–cisplatin followed by ifosfamide–gemcitabine according to the ‘worst drug rule’ hypothesis in patients with locally advanced unresectable stage IIIB or metastatic stage IV non-small cell lung cancer. The primary endpoint was survival parameters, while secondary endpoints included analysis of response rates and toxicity. Patients and methods: patients were randomized to receive: (a) gemcitabine 1000 mg/m2 on days 1, 8 and 15…
Gemcitabine plus vinorelbine in stage IIIB or IV non-small cell lung cancer (NSCLC): A multicentre phase II clinical trial
2001
Abstract A phase II study in patients with stage IIIB/IV non-small cell lung cancer (NSCLC) was carried out to evaluate the clinical activity and toxicity of the chemotherapeutic combination of gemcitabine+vinorelbine (GEM/VNR). Forty-five patients (40 male, 5 female) with a median age of 67 years (range 37–73) and a median ECOG performance status of 1 (range 0–2) were enrolled into the trial. Twenty patients had stage IIIB (two positive supraclavicular nodes and 20 cytologically positive pleural effusion), and 25 had stage IV NSCLC. GEM 1000 mg/m 2 diluted in 250 cc 3 of normal saline was administered iv on days 1, 8, and 15, while VNR was given 30 mg/m 2 on days 1 and 8 every 4 weeks. The…
Vinorelbine plus cisplatin versus cisplatin plus vindesine and mitomycin C in stage IIIB-IV non-small cell lung carcinoma: a prospective randomized s…
2002
Abstract Purpose: To compare a regimen of vinorelbine and cisplatin (VC) to the combination of mitomycin, vindesine, and cisplatin (MVP) in patients with stage IIIB or stage IV non-small cell lung cancer (NSCLC). The main endpoits were analysis of objective response rates, toxicity, time to progression, and overall survival. Patients and methods: 247 eligible patients were randomized to receive (a) vinorelbine 25 mg/m 2 intravenous bolus on days 1and 8 plus cisplatin 100 mg/m 2 on day 1 every 4 weeks, or (b) mitomycin c 8 mg/m 2 i.v. on day 1, vindesine 3 mg/m 2 i.v. on days 1, 8, 15 and 22, plus cisplatin 100 mg/m 2 on day 1 every 4 weeks. In subsequent cycles vindesine was given every oth…
Soot-exposed mononuclear cells increase inflammatory cytokine mRNA expression and protein secretion in cocultured bronchial epithelial cells.
2000
<i>Background:</i> Soot particles are air pollutants capable of inducing airway and lung parenchymal injury. Mononuclear and bronchial epithelial cells are central to the maintenance of homeostasis and inflammation in the airways. <i>Objectives:</i> The aim of this study was to evaluate the contribution of mononuclear cells to the release of inflammatory mediators by bronchial epithelial cells. <i>Methods:</i> To model the in vivo situation, an in vitro system of cocultured blood monocytes and BEAS-2B cells was established in a transwell system. Blood monocytes were exposed to soot particles (FR 101) at concentrations of up to 100 μg/10<sup>6</su…
Production of reactive oxygen intermediates by human macrophages exposed to soot particles and asbestos fibers and increase in NF-kappa B p50/p105 mR…
1999
Alveolar macrophages (AM) play a decisive role in the immunologic defense system of the lung and in inflammatory pulmonary pathomechanisms. AM and blood monocytes (BM) were exposed to chrysotile B, soot FR 101, and Printex 90 (P 90). We evaluated the reactive oxygen intermediate (ROI) release of AM and BM after particle exposure. ROI release was measured by chemiluminescence. Thirty-minute exposure caused a significant (up to 2.5-fold) increase in ROI release of AM (100 micrograms/10(6) cells) compared with control experiments (p0.01). Identical exposure conditions for BM resulted in a similar reaction pattern (maximum 2.2-fold increase in ROI release; p0.05). After a 90-min particle exposu…
Bronchial asthma and personality dimensions: a multifaceted association.
1994
Personality dimensions seem to play an important role in chronic diseases by maintaining or increasing the patient's physical complaints. This study examines in bronchial asthma: (a) the relationships among clinical data, baseline lung function, and personality traits; and (b) the patient's characteristics related to the physician's judgement about his or her asthma severity. Five questionnaires measuring anxiety, depression, self-consciousness, and subjective symptoms were completed by 51 asthmatic patients. Responses to questionnaires and clinical and demographic data were factor-analyzed. Factor analysis revealed that the physician's severity judgement is based on elderly age, high score…
