Significant reductions in alcohol use after hepatitis C treatment: results from the ANRS CO13-HEPAVIH cohort

2017

BACKGROUND AND AIMS: Few data exist on changes to substance use patterns before and after hepatitis C virus (HCV) treatment. We used longitudinal data of HIV-HCV co-infected individuals to examine whether receiving pegylated interferon (Peg-IFN)-based therapy irrespective of HCV clearance could modify tobacco, cannabis and alcohol use. DESIGN: A prospective cohort of HIV-HCV co-infected individuals was enrolled from 2006. Participants' clinical data were retrieved from medical records and socio-demographic and behavioural characteristics were collected by yearly self-administered questionnaires. SETTING: Data were collected across 17 hospitals in France. PARTICIPANTS: All HIV-HCV co-infecte…

Patient-to-patient transmission of hepatitis C virus (HCV) during colonoscopy diagnosis

2010

Abstract Background No recognized risk factors can be identified in 10-40% of hepatitis C virus (HCV)-infected patients suggesting that the modes of transmission involved could be underestimated or unidentified. Invasive diagnostic procedures, such as endoscopy, have been considered as a potential HCV transmission route; although the actual extent of transmission in endoscopy procedures remains controversial. Most reported HCV outbreaks related to nosocomial acquisition have been attributed to unsafe injection practices and use of multi-dose vials. Only a few cases of likely patient-to-patient HCV transmission via a contaminated colonoscope have been reported to date. Nosocomial HCV infecti…

Myocardial fibrosis by delayed enhancement cardiovascular magnetic resonance and HCV infection in thalassemia major patients.

2010

Abstract Abstract 4265 Introduction. Delayed enhancement (DE) cardiac magnetic resonance (CMR) technique with intravenous administration of gadolinium (Gd) chelates contrast agents is the only validated non-invasive approach for detecting myocardial fibrosis (Mahrholdt H et al, Eur Heart J 2005). This technique has been confirmed safe in patients with hemoglobinopathies (Meloni A et al, Haematologica 2009). In thalassemia major (TM), myocardial fibrosis has been detected using the DE technique and a positive correlation with anti-HCV antibodies has been described (Pepe A et al, Heart 2009). However, HCV-induced cardiomyopathy is still controversial (Matsumori A et al. J Card Fail 2006). The…

Guidelines for palliative surgery of cholangiocarcinoma

2008

AbstractThe aims of the guidelines are to help assess the evidence for palliation surgery in patients with cholangiocarcinoma (CCA). The guidelines are classified in accordance with the location of the primary lesion, i.e. intrahepatic, hilar, and distal. They are based on comprehensive literature surveys, including results from randomized controlled trials, systematic reviews and meta-analysis, and cohort, prospective, and retrospective studies. Intrahepatic CCA, i.e. resection of lymph-node-positive tumors and R1/R2 resections have not been shown to provide survival benefit: Evidence levels: 2b, 4; Recommendation grade C. Hilar CCA: R1 resection is justified as a very efficient palliation…

Incidence of HSV and HPV with azathioprine

2009

IBd Incidence of HSV and HPV with azathioprine Mario Cottone and Sara Renna severe infections are an established risk of immunosuppressive therapy; however, the risk of opportunistic infections in patients with IBd who receive immunosuppressive therapy has so far only been studied retrospectively. the increased incidence of herpes flares and development or worsening of viral warts in patients with IBd who receive azathioprine has now been demonstrated for the first time in a prospective study. the rate of opportunistic infections in patients with iBD is dependent on the patient’s nutritional status, degree of innate immune system activity, whether the patient has undergone surgery and their…

Treatment of acute hepatitis C in human immunodeficiency virus-infected patients: The HEPAIG study

2010

Acute hepatitis C continues to be a concern in men who have sex with men (MSM), and its optimal management has yet to be established. In this study, the clinical, biological, and therapeutic data of 53 human immunodeficiency virus (HIV)-infected MSM included in a multicenter prospective study on acute hepatitis C in 2006-2007 were retrospectively collected and analyzed. The mean hepatitis C virus (HCV) viral load at diagnosis was 5.8 ± 1.1 log10 IU/mL (genotype 4, n = 28; genotype 1, n = 14, genotype 3, n = 7). The cumulative rates of spontaneous HCV clearance were 11.0% and 16.5% 3 and 6 months after diagnosis, respectively. Forty patients were treated, 38 of whom received pegylated interf…

Inflammatory manifestations at colonoscopy in patients with colonic diverticular disease

2010

Aliment Pharmacol Ther 2011; 33: 358–365 Summary Background  Ulcerative colitis with diverticulosis (UCD), segmental colitis associated with diverticulosis (SCAD) and acute uncomplicated diverticulitis (AUD) may affect the same colonic regions, but the real incidence of these entities in clinical practice is unknown. Aim  To assess the incidence and the endoscopic findings of UCD, SCAD and AUD. Methods  From January 2004 to June 2009, 8525 consecutive colonoscopies were performed. Diagnosis of the diseases was based on specific endoscopic and histological (UCD and SCAD), and on endoscopic and radiological (AUD) patterns. Results  Ulcerative colitis with diverticulosis was diagnosed in 25 pa…

Die Hochenergetische Extrakorporale Stoßwellentherapie (ESWT) in der Behandlung von Pseudarthrosen

2008

PROBLEM The success rate of high-energy extracorporal shock wave therapy in the treatment of non-unions in comparison to the "golden standard" surgery is still unclear. METHOD In a prospective study, 3000 impulses with an energy density of 0.6 mJ/mm2 were applied with an experimental device to the pseudarthrosis in 52 patients. RESULTS The mean duration of pseudarthrosis was 13 months. A mean of 2.5 surgical interventions had already been performed. Bony union was achieved in 52% of our patients after an average of 3.3 months. Failures especially were found in the atrophic type of pseudarthrosis as well as in congenital bone disorders like fibrous dysplasia or osteogenesis imperfecta. No se…

Treatment Persistence and Safety of Apremilast in Psoriasis: Experience With 30 Patients in Routine Clinical Practice

2020

Apremilast is a phosphodiesterase-4 inhibitor taken orally. Little information about its use in routine clinical practice is available. We aimed to assess treatment safety and persistence rates in patients on apremilast for different forms of plaque psoriasis. This observational retrospective study included 30 patients with psoriasis who were treated with apremilast between January 2016 and December 2017 in our hospital. Twelve patients had palmar-plantar psoriasis, 8 had plaque psoriasis mainly on the scalp, and 10 had plaque psoriasis in other locations. The probable period of treatment persistence in patients in the 50th percentile was 18.5 months according to survival analysis of the se…

Determination of Minimal Erythema Dose and Anomalous Reactions to UVA Radiation by Skin Phototype

2014

Background: Phototesting is a technique that assesses the skin’s sensitivity to UV radiation by determining the smallest dose of radiation capable of inducing erythema (minimal erythema dose [MED]) and anomalous responses to UV-A radiation. No phototesting protocol guidelines have been published to date. Methodology: This was a multicenter prospective cohort study in which 232 healthy volunteers were recruited at 9 hospitals. Phototests were carried out with solar simulators or fluorescent broadband UV-B lamps. Each individual received a total of 5 or 6 incremental doses of erythemal radiation and 4 doses of UV-A radiation. The results were read at 24 hours. Results: At hospitals where sola…
