Convergent sets of data from in vivo and in vitro methods point to an active role of Hsp60 in chronic obstructive pulmonary disease pathogenesis.
2011
BackgroundIt is increasingly clear that some heat shock proteins (Hsps) play a role in inflammation. Here, we report results showing participation of Hsp60 in the pathogenesis of chronic obstructive pulmonary diseases (COPD), as indicated by data from both in vivo and in vitro analyses.Methods and resultsBronchial biopsies from patients with stable COPD, smoker controls with normal lung function, and non-smoker controls were studied. We quantified by immunohistochemistry levels of Hsp10, Hsp27, Hsp40, Hsp60, Hsp70, Hsp90, and HSF-1, along with levels of inflammatory markers. Hsp10, Hsp40, and Hsp60 were increased during progression of disease. We found also a positive correlation between th…
Localisation of mediterranean Kaposi's sarcoma in Morgagni's ventricle
2011
Objective: Head and neck involvement in Kaposi’s Sarcoma (KS) is not unusual . However, laryngeal involvement is a relatively infrequent manifestation and ENT specialists should consider it in differential diagnosis in laryngeal lesions of AIDS patients and/or subjects from the Mediterranean area. Methods: Case report and review of the literature in English Clinical Case: Male patient presenting with a three- month history of cough and acute dispnoea. Laryngoscopy identified a laryngeal mass occluding the glottic plane. Tracheotomy was then performed and the laryngeal lesion was removed. Histopathology showed neoplastic spindle cells that were positive to immunostain with CD-31 and CD-34, a…
Improving survival with deferiprone treatment in patients with thalassemia major: A prospective multicenter randomised clinical trial under the auspi…
2009
The prognosis for thalassemia major has dramatically improved in the last two decades. However, many transfusion-dependent patients continue to develop progressive accumulation of iron. This can lead to tissue damage and eventually death, particularly from cardiac disease. Previous studies that investigated iron chelation treatments, including retrospective and prospective non-randomised clinical trials, suggested that mortality, due mainly to cardiac damage, was reduced or completely absent in patients treated with deferiprone (DFP) alone or a combined deferiprone-deferoxamine (DFP-DFO) chelation treatment. However, no survival analysis has been reported for a long-term randomised control …
Longterm Retention of Tumor Necrosis Factor-α Inhibitor Therapy in a Large Italian Cohort of Patients with Rheumatoid Arthritis from the GISEA Regist…
2012
Objective.To evaluate 4-year retention rates of tumor necrosis factor-α (TNF-α) inhibitors adalimumab, etanercept, and infliximab among patients with longstanding rheumatoid arthritis (RA), as derived from an Italian national registry.Methods.The clinical records of 853 adult patients with RA in the GISEA (Gruppo Italiano Studio Early Arthritis) registry were prospectively analyzed to compare drug survival rates and the baseline factors that may predict adherence to therapy.Results.In 2003 and 2004, 324 patients started treatment with adalimumab, 311 with etanercept, and 218 with infliximab. After 4 years, the global retention rate of anti-TNF-α therapy was 42%. Etanercept survival (51.4%) …
Sirolimus Use in Liver Transplant Recipients With Hepatocellular Carcinoma: A Randomized, Multicenter, Open-Label Phase 3 Trial
2016
International audience; BACKGROUND:We investigated whether sirolimus-based immunosuppression improves outcomes in liver transplantation (LTx) candidates with hepatocellular carcinoma (HCC).METHODS:In a prospective-randomized open-label international trial, 525 LTx recipients with HCC initially receiving mammalian target of rapamycin inhibitor-free immunosuppression were randomized 4 to 6 weeks after transplantation into a group on mammalian target of rapamycin inhibitor-free immunosuppression (group A: 264 patients) or a group incorporating sirolimus (group B: 261). The primary endpoint was recurrence-free survival (RFS); intention-to-treat (ITT) analysis was conducted after 8 years. Overal…
Papillary muscle relocation in conjunction with valve annuloplasty improve repair results in severe ischemic mitral regurgitation
2012
OBJECTIVE: The incidence of recurrent mitral regurgitation (MR) after restrictive annuloplasty (RA) was 5% to 20% in several reports. There are many opinions in favor of adding subvalvular procedures to RA to reduce the tenting forces and improve the repair results. METHODS: From March 2003 to May 2010, 55 patients with severe ischemic MR who had undergone papillary muscle (PPM) relocation in conjunction with mitral annuloplasty in our institutions were enrolled. The patients were matched 1:1 with those who underwent isolated RA using the propensity score. The mean left ventricular ejection fraction was 42% ± 6%. The mean tenting area and coaptation depth was 3.2 ± 0.6 cm(2) and 1.3 ± 0.2 c…
Clinical course of patients with symptomatic isolated superficial vein thrombosis: the ICARO follow‐up study
2017
Essentials Late sequelae of isolated superficial vein thrombosis (iSVT) have rarely been investigated. We studied 411 consecutive outpatients with acute iSVT with a median follow-up of three years. Male sex and cancer are risk factors for future deep vein thrombosis or pulmonary embolism. Patients without cancer appear to be at a negligible risk for death. SUMMARY Background Studies of long-term thromboembolic complications and death following acute isolated superficial vein thrombosis (iSVT) of the lower extremities are scarce. Objectives To investigate the course of iSVT in the setting of an observational multicenter study. Methods We collected longitudinal data of 411 consecutive outpati…
Concordance and Clinical Significance of Uncommon Variants of Bladder Urothelial Carcinoma in Transurethral Resection and Radical Cystectomy Specimens
2014
To evaluate the concordance and prognostic role of histologic variants of bladder urothelial carcinoma in transurethral resection of bladder tumor (TURBT) and radical cystectomy (RC) specimens. METHODS Clinicopathologic information available at the time of RC and follow-up data from 4110 RC specimens, collected between January 2000 and December 2009 at 17 tertiary referral centers were retrospectively analyzed and evaluated for the presence or absence of uncommon variants of bladder urothelial carcinoma. The presence or absence of uncommon variants of bladder urothelial carcinoma was evaluated on previous TURBT specimens of patients undergoing RC. Cox regression was used to assess the impac…
Delayed-type hypersensitivity in classic Kaposi sarcoma patients and controls
2011
Background: Immune perturbation likely affects the development of Kaposi sarcoma (KS) among people infected with the KS-associated herpesvirus (KSHV). We tested whether KSHV-seropositive individuals or cases of classic KS (cKS), which typically originates in the leg, had differing delayed-type hypersensitivity (DTH) in the forearm or leg. Methods: Mantoux DTH with three antigens (Candida, tetanus, PPD) was performed on the forearm and leg of 15 cKS cases, 14 KSHV-positives without KS, and 15 KSHV-negative controls. The diameters of induration responses were compared by group and body site. Results: Leg DTH was greater than forearm DTH among controls (mean difference 5.6 mm, P=0.0004), where…
Effects of immunomodulatory treatment with subcutaneous interferon beta-1a on cognitive decline in mildly disabled patients with relapsing-remitting …
2010
The objective of this study was to assess the effects of subcutaneous (sc) interferon beta-1a (IFNβ-1a) on cognition in mildly disabled patients with relapsing—remitting multiple sclerosis (RRMS). Patients aged 18—50 years with RRMS (McDonald criteria; Expanded Disability Status Scale score ≤4.0) were assigned IFNβ therapy at the physician’s discretion and underwent standardized magnetic resonance imaging, neurological examination and neuropsychological testing at the baseline and regular intervals for up to three years. This analysis included 459 patients who received sc IFNβ-1a (44 mcg: n = 236; 22 mcg: n = 223; three-year follow up was available for 318 patients). The hazard ratio for c…
