    The aim of this study was the identification of subgroups of patients at higher risk of nonadherence to adjuvant hormone therapy for breast cancer. Using recursive partitioning and amalgamation (RECPAM) analysis, the highest risk was observed in the group of unmarried, employed women, or housewives. This result might be functional in designing tailored intervention studies aimed at improvement of adherence. Background: Adherence to adjuvant endocrine therapy (HT) is suboptimal among breast cancer patients. A high rate of nonadherence might explain differences in survival between clinical trial and clinical practice. Tailored interventions aimed at improving adherence can only be implemented if subgroups of patients at higher risk of poor adherence are identified. Because no data are available for Italy, we undertook a large survey on adherence among women taking adjuvant HT for breast cancer. Patients and Methods: Patients were recruited from 10 cancer clinics in central Italy. All patients taking HT for at least 1 year were invited, during one of their follow-up visit, to fill a confidential questionnaire. The association of sociodemographic and clinical characteristics of participants with adherence was assessed using logistic regression. The RECPAM method was used to evaluate interactions among variables and to identify subgroups of patients at different risk of nonadherence. Results: A total of 939 patients joined the study and 18.6% of them were classified as nonadherers. Among possible predictors, only age, working status, and switching from tamoxifen to an aromatase inhibitor were predictive of nonadherence in multivariate analysis. RECPAM analysis led to the identification of 4 classes of patients with a different likelihood of nonadherence to therapy, the lowest being observed in retired women with a low level of education, the highest in the group of unmarried, employed women, or housewives. Conclusion: The identification of these subgroups of “real life” patients with a high prevalence of nonadherers might be functional in designing intervention studies aimed at improving adherenc

    Background: Both inflammatory and remodelling processes are associated with irreversible airway obstruction observed in severe asthma. Our aim was to characterize a group of severe asthmatic patients with or without persistent airway obstruction in relation to specific sputum inflammatory and remodelling biomarkers. Methods: Forty-five patients under regular high-dose inhaled corticosteroid/ß-2agonist treatment were studied, after a follow-up period of at least 2 years, with a minimum of 4 visits. Periostin, TGF-ß, RANTES, IL-8, GM-CSF, FGF-2, and cell counts were measured in induced sputum. Serum periostin was also measured. Results: Sputum induction was successfully performed in all but 5 patients. There were no significant differences in demographic and clinical data between patients with non-persistent obstruction (NO: FEV1/VC>88%pred.) and those with persistent obstruction (O: a not completely reversible obstruction with FEV1/VC<88%pred. at each visit before the study visit). Patients with persistent obstruction had significantly higher sputum periostin and TGF-ß concentrations than NO patients and a trend of higher serum periostin levels. GM-CSF and FGF-2 were significantly increased in NO compared to O patients. No differences between groups were found for RANTES, IL-8 and differential cell counts. Sputum periostin inversely correlated with functional parameters (prebronch. FEV1: rho = −0.36, p < 0.05; postbronch. FEV1: rho = −0.33, p = 0.05). Patients with high sputum periostin concentration (>103.3 pg/ml: median value) showed an absolute number of sputum eosinophils significantly higher than patients with low sputum periostin; this behavior was unobserved when serum periostin was considered. Conclusions: Only periostin and TGF-ß identified a subgroup of severe asthmatic patients with persistent airway obstruction. Sputum periostin was also inversely associated with FEV1 and proved to be a more sensitive biomarker than serum periostin to identify severe asthmatics with higher sputum eosinophilia

    Background. Oxidative stress plays a role in the pathogenesis of many chronic inflammatory lung diseases. Exhaled breath condensate (EBC) collection is a noninvasive method to investigate pulmonary oxidative stress biomarkers such as malondialdehyde (MDA). Subjects and Methods. We measured MDA levels in EBC in a large number of patients (N = 194) with respiratory diseases: asthma (N = 64), bronchiectasis (BE, N = 19), chronic obstructive pulmonary disease (COPD, N = 73), idiopathic pulmonary fibrosis (IPF, N = 38). Fourteen healthy nonsmoking subjects were included as controls. Results. Excluding IPF subjects, MDA levels were significantly higher in all disease groups than in control group. MDA was significantly higher in COPD than asthmatic and BE subjects. Among asthmatics, corticosteroids-treated subjects had lower MDA levels than untreated subjects. COPD subjects showed an inverse correlation between MDA concentrations and FEV1% (rho:  −0.24, P < .05). Conclusions. EBC-MDA is increased in subjects with chronic airway disorders, particularly in COPD, and it is related to FEV1 reduction

    Upper and lower airway inflammation in severe asthmatics: a guide for a precision biologic treatment

    Get PDF
    Background and aims: Severe asthma may require the prescription of one of the biologic drugs currently available, using surrogate markers of airway inflammation (serum IgE levels and allergic sensitization for anti-IgE, or blood eosinophils for anti-IL5/IL5R). Our objective: to assess upper and lower airway inflammation in severe asthmatics divided according to the eligibility criteria for one of the target biologic treatments. Methods: We selected 91 severe asthmatics, uncontrolled despite high-dose ICS-LABA, and followed for &gt;6 months with optimization of asthma treatment. Patients underwent clinical, functional and biological assessment, including induced sputum and nasal cytology. They were then clustered according to the eligibility criteria for omalizumab or mepolizumab/benralizumab. Results: Four clusters were selected: A (eligible for omalizumab, n = 23), AB (both omalizumab and mepolizumab, n = 26), B (mepolizumab, n = 22) and C (non-eligible for both omalizumab and mepolizumab, n = 20). There was no difference among clusters for asthma control (Asthma Control Test and Asthma Control Questionnaire 7), pre-bronchodilator forced expiratory volume in 1 s, serum IgE and fractional exhaled nitric oxide levels. Sputum eosinophils were numerically higher in clusters AB and B, in agreement with the higher levels of blood eosinophils. Allergic rhinitis was more frequent in clusters A and AB, while chronic rhinosinusitis with nasal polyps prevalence increased progressively from A to C. Eosinophils in nasal cytology were higher in clusters AB, B and C. Conclusion: Eosinophilic upper and lower airway inflammation is present in the large majority of severe asthmatics, independently from the prescription criteria for the currently available biologics, and might suggest the use of anti-IL5/IL5R or anti IL4/13 also in patients without blood eosinophilia.

    ABSTRACT Breast conserving therapy (BCT) including postoperative irradiation of the remaining breast tissue is generally accepted as the best treatment for the majority of patients with early-stage breast cancer. The question is whether there is a necessity for irradiating all patients. Between 2001 and 2005, 749 women aged 55–75 years with infiltrating breast carcinoma were randomly assigned to breast conservative surgery, with or without radiotherapy (RT), to evaluate the incidence of in-breast recurrence (IBR). After 5 years of median follow-up, the cumulative incidence of IBR was 2.5% in the surgery-only arm and 0.7% in the surgery plus RT arm. There are no differences in terms of overall survival and distant disease-free survival. The preliminary evaluation suggests that breast irradiation after conservative surgery can be avoided without exposing these patients to an increased risk of distant-disease recurrence. Prolonged follow-up will further clarify the possible risks and late sequelae potentially induced by breast RT

    predict the quality of the sputum samples obtained in a large group of asthmatic subjects. Methods. We compared the presence of sputum productive cough in the days preceding the test, easiness in expectoration during the test, and sputum macroscopic aspect (presence of visible plugs) with the quality of slides obtained from sputum processing. We also monitored changes in the quality in patients who repeated sputum collection several times, comparing those whose first sample was adequate with those whose first sample was inadequate. We analysed 547 sputum samples obtained from 238 asthmatic patients. Sputum was processed using the whole sample method. Results. Patients with productive cough in the days preceding the test and easy expectoration during the test produced a higher percentage of adequate samples than those without productive cough (86% vs 76%, p=0.01) and with difficulty in expectoration (85% vs 63%, p=0.0001). "Good" macroscopic samples were associated with better quality of slides (91% vs 38%, p=0.0001). Patients with inadequate first sample (n=40) had a higher percentage of inadequate samples (55%) in the subsequent tests than patients (n=115) with adequate first sample (8%). Conclusions. Patients with increased airway secretions in the days preceding the test, easy expectoration and "good" macroscopic aspect of the sputum are more likely to produce sputum sample adequate for inflammatory cell analysis. If the first sputum sample is adequate, subsequent samples are very likely to be adequate as well. If the first sputum sample is inadequate, the quality of subsequent samples cannot be predicted, since there are similar probabilities of having adequate or inadequate samples

    Artificial subterranean habitats can be of important ecological interest. Draining galleries are a typology of artificial springs with underground development characterized by an almost horizontal tunnel that penetrates the side of a slope, to catch the subterranean water and bring it outward. They are a very ancient spring catching technique and provide interesting unstudied subterranean habitats. In this study we surveyed 18 draining galleries in NW Italy. We provide specific environmental data that can help to support broad conclusions on the ecological features and value of these habitats. We found that they house permanent waterbodies, have lengths up to 120 m, are characterized by climatic conditions similar to those of natural caves. We collected several taxa of organisms, adapted to subterranean life as well as coming from outside environment, which find inside draining galleries shelter, roosting and breeding sites. We tested the role of accessibility in determining galleries biodiversity and we found that the latter is scarcely affected. From a conservationist point of view draining galleries can have important ecological value, particularly in areas devoid of natural subterranean habitatsLes environnements souterrains artificiels peuvent ĂȘtre trĂšs intĂ©ressants d'une point de vue Ă©cologique. Les galeries drainantes sont des sources artificielles avec un dĂ©veloppement hypogĂ© constituĂ© par une galerie presque horizontale qui s'Ă©tend Ă  l'intĂ©rieur d'un relief. Il s'agit d'une technique de captage trĂšs ancienne qui a crĂ©Ă© des habitats souterrains non ou peu Ă©tudiĂ©s et qui sont potentiellement trĂšs intĂ©ressants d'un point de vue Ă©cologique. Nous avons Ă©tudiĂ© 18 galeries drainantes dans le nord-ouest de l'Italie. Nous prĂ©sentons des donnĂ©es Ă©cologiques spĂ©cifiques qui peuvent aider Ă  formuler des conclusions gĂ©nĂ©rales sur les caractĂ©ristiques Ă©cologiques de ces habitats hypogĂ©s. Les galeries drainantes, qui dans la rĂ©gion d'Ă©tude atteignent 120 m de longueur, offrent la prĂ©sence de biotopes humides permanents et ont des caractĂ©ristiques climatiques semblables Ă  celles des grottes. Elles constituent des refuges et des sites de reproduction tant Ă  des organismes typiques de la faune cavernicole qu'Ă  beaucoup de taxons provenant de l'extĂ©rieur. Nous n'avons pas observĂ© d'influence statistiquement significative de l'accessibilitĂ© des sites sur leur niveau de biodiversitĂ©. Du point de vue de la conservation les galeries de drainage prĂ©sentent une valeur Ă©cologique certaine, surtout dans les zones dĂ©pourvues d'environnements souterrains naturels

    Treatment of loco-regional recurrence of nasopharyngeal carcinoma in a non-endemic area: oncologic outcomes, morbidity, and proposal of a prognostic nomogram

    Get PDF
    Introduction: The study assessed outcomes and toxicities of different treatment modalities for local and/or regional recurrent nasopharyngeal carcinoma (NPC) in a non-endemic area. Methods: Patients treated with curative intent for recurrent NPC with salvage surgery, photon-based radiotherapy, proton therapy (PT), with or without chemotherapy, at different Italian referral centers between 1998 and 2020 were included. Adverse events and complications were classified according to the Common Terminology Criteria for Adverse Events. Characteristics of the patients, tumors, treatments, and complications are presented along with uni- and multivariate analysis of prognostic factors. A survival predictive nomogram is also provided. Results: A total of 140 patients treated from 1998 to 2020 were retrospectively assessed. Cases with lower age, comorbidity rate, stage, and shorter disease-free interval (DFI) preferentially underwent endoscopic surgery. More advanced cases underwent re-irradiation, fairly distributed between photon-based radiotherapy and PT. Age and DFI were independent factors influencing overall survival. No independent prognostic effect of treatment modality was observed. No significant difference in the morbidity profile of treatments was observed, with 40% of patients experiencing at least one adverse event classified as G3 or higher. Conclusion: Recurrent NPC in a non-endemic area has dissimilar aspects compared to its endemic counterpart, suggesting the need for further studies that can guide the choice of the best treatment modality

    Contribution by Polymorphonucleate Granulocytes to Elevated Gamma-Glutamyltransferase in Cystic Fibrosis Sputum

    Get PDF
    Background: Cystic fibrosis (CF) is an autosomal recessive disorder characterized by a chronic neutrophilic airways inflammation, increasing levels of oxidative stress and reduced levels of antioxidants such as glutathione (GSH). Gammaglutamyltransferase (GGT), an enzyme induced by oxidative stress and involved in the catabolism of GSH and its derivatives, is increased in the airways of CF patients with inflammation, but the possible implications of its increase have not yet been investigated in detail. Principal Findings: The present study was aimed to evaluate the origin and the biochemical characteristics of the GGT detectable in CF sputum. We found GGT activity both in neutrophils and in the fluid, the latter significantly correlating with myeloperoxidase expression. In neutrophils, GGT was associated with intracellular granules. In the fluid, gel-filtration chromatography showed the presence of two distinct GGT fractions, the first corresponding to the human plasma b-GGT fraction, the other to the free enzyme. The same fractions were also observed in the supernatant of ionomycin and fMLPactivated neutrophils. Western blot analysis confirmed the presence of a single band of GGT immunoreactive peptide in the CF sputum samples and in isolated neutrophils. Conclusions: In conclusion, our data indicate that neutrophils are able to transport and release GGT, thus increasing GGT activity in CF sputum. The prompt release of GGT may have consequences on all GGT substrates, including major inflammatory mediators such as S-nitrosoglutathione and leukotrienes, and could participate in early modulation of inflammatory response
