RESUMEN

BACKGROUND: Worldwide, chronic obstructive pulmonary disease (COPD) remains largely underdiagnosed. AIM: To assess whether the use of Global Initiative for Chronic Obstructive Lung Disease (GOLD) questions and COPD coordination, either alone or combined, would detect new COPD cases in primary care. DESIGN AND SETTING: GPs in Brittany, France, systematically enrolled patients aged 40-80 years over a 4-month period in this French multicentre cluster randomised controlled study. METHOD: GPs were randomly allocated to one of four groups: control (standard of care), GOLD questions (adapted from symptoms and risk factors identified by GOLD), COPD coordination, and GOLD questions with COPD coordination. New cases of COPD were those confirmed by spirometry: post-bronchodilator forced expiratory volume in 1 second over forced vital capacity of <0.7. RESULTS: In total, 11 430 consultations were conducted by 47 GPs, who enrolled 3162 patients who did not have prior diagnosed asthma or COPD. Among these, 802 (25%) were enrolled in the control, 820 (26%) in the GOLD questions, 802 (25%) in the COPD coordination, and 738 (23%) in the GOLD questions with COPD coordination groups. In the control group, COPD was not evoked, and no spirometry was prescribed. All new cases of COPD diagnosed (n = 24, 0.8%) were in the intervention groups, representing 6.8% of patients who performed spirometry. Statistically significantly more new cases of COPD were detected with COPD coordination (P = 0.01). CONCLUSION: Interventions that can be easily implemented, such as the GOLD questions and COPD coordination, can identify new cases of COPD. Studies are needed to identify the most appropriate case-finding strategies for GPs to detect COPD in primary care for each country.

RESUMEN

INTRODUCTION: Hepatitis C virus (HCV) may recur after liver transplantation (LT) in the severe form of fibrosing cholestatic hepatitis (FCH). The prognosis dramatically improved by the use of direct acting antivirals (DAAs). The aim of the present study was to describe the change in histological features of FCH after virological eradication. METHODS: From the ANRS CUPILT cohort we included 17 patients who presented FCH and at least two graft biopsies, one before DAA-treatment and one after. A single expert pathologist, blinded for clinical outcome, retrospectively confirmed the diagnosis of FCH and progression of fibrosis. RESULTS: Diagnosis of FCH was made after a median [IQR] 6.0 [3.1-11.8] months after LT, and the median interval between diagnosis and onset of treatment was 1.2 [0.7-6.1] months. The rate of viral eradication was 94.1%. The median delay between the pre-treatment and the treatment biopsies was 12.5 [11.1-20.0] months. Between the end of treatment and the second biopsy, the delay was 5.3 [0.6-7.4] months. Fibrosis stage worsened in 10 patients (58.8%); 6 patients had cirrhosis (35.3%). Chronic rejection appeared in 4 (23.5%) patients. CONCLUSION: Our results suggest that, despite viral eradication in patients presenting FCH after LT, fibrosis progression was observed in half of patients. This should encourage monitoring fibrosis progression despite HCV cure.

RESUMEN

Good clinical practice (GCP) is an international ethical and scientific quality standard for the design, conduct, performance, monitoring, auditing, recording, analyses and reporting of clinical trials. Before the start of a clinical trial, investigators commit to perform the research in accordance with GCPs, regulatory dispositions and protocol. The sponsors are responsible for investigators' selection and for controlling their skills. Whereas industrial sponsors systematically require a certificate of GCP training, academic sponsors seem to be less demanding. We have carried out two surveys between April and June 2018. A first questionnaire was sent to the 40 French academic directions of clinical research and innovation in order to determine their requirements about the GCP training of the investigators participating in their trials. The second questionnaire was transmitted to physicians of the "Bretagne recherche clinique hospitalière network": Rennes, Saint-Malo, Saint-Brieuc, Vannes, Lorient and Pontivy hospitals, in order to determine the GCP certification rate, and their needs in terms of clinical research training. Twenty-eight (70%) directions of clinical research answered the first survey, among which 18 (64%) required systematically the investigators' GCP certification in case of category 1 interventional studies. This rate decreased for category 2 (50%) and non-interventional category 3 (18%) studies. A total of 345 physicians answered the second survey, among which 263 (76%) had already been clinical trial investigators. However, only 29% of all physicians and 54% of those who had been principal investigator were certified for GCP training. These results support the need for large campaigns of GCP training in public hospitals.

RESUMEN

AIMS: Monitoring risk-based approaches in clinical trials are encouraged by regulatory guidance. However, the impact of a targeted source data verification (SDV) on data-management (DM) workload and on final data quality needs to be addressed. METHODS: MONITORING was a prospective study aiming at comparing full SDV (100% of data verified for all patients) and targeted SDV (only key data verified for all patients) followed by the same DM program (detecting missing data and checking consistency) on final data quality, global workload and staffing costs. RESULTS: In all, 137 008 data including 18 124 key data were collected for 126 patients from 6 clinical trials. Compared to the final database obtained using the full SDV monitoring process, the final database obtained using the targeted SDV monitoring process had a residual error rate of 1.47% (95% confidence interval, 1.41-1.53%) on overall data and 0.78% (95% confidence interval, 0.65-0.91%) on key data. There were nearly 4 times more queries per study with targeted SDV than with full SDV (mean ± standard deviation: 132 ± 101 vs 34 ± 26; P = .03). For a handling time of 15 minutes per query, the global workload of the targeted SDV monitoring strategy remained below that of the full SDV monitoring strategy. From 25 minutes per query it was above, increasing progressively to represent a 50% increase for 45 minutes per query. CONCLUSION: Targeted SDV monitoring is accompanied by increased workload for DM, which allows to obtain a small proportion of remaining errors on key data (<1%), but may substantially increase trial costs.

RESUMEN

Sofosbuvir (SOF) combined with nonstructural protein 5A (NS5A) inhibitors has demonstrated its efficacy in treating a recurrence of hepatitis C virus (HCV) after liver transplantation (LT). However, the duration of treatment and need for ribavirin (RBV) remain unclear in this population. Our aim was to determine whether LT recipients could be treated with an SOF + NS5A inhibitor-based regimen without RBV for 12 weeks post-LT. Between October 2013 and December 2015, 699 LT recipients experiencing an HCV recurrence were enrolled in the multicenter ANRS CO23 CUPILT cohort. We selected patients receiving SOF and NS5A inhibitor ± RBV and followed for at least 12 weeks after treatment discontinuation. The primary efficacy endpoint was a sustained virological response 12 weeks after the end of treatment (SVR12). Among these 699 patients, 512 fulfilled the inclusion criteria. Their main characteristics were: 70.1% genotype 1, 18.2% genotype 3, 21.1% cirrhosis, and 34.4% previously treated patients. We identified four groups of patients according to their treatment and duration: SOF + NS5A without RBV for 12 (156 patients) or 24 (239 patients) weeks; SOF + NS5A + RBV for 12 (47 patients) or 24 (70 patients) weeks. SVR12 values reached 94.9%, 97.9%, 95.7%, and 92.9%, respectively (P = 0.14). Only 20 patients experienced a treatment failure. Under multivariate analysis, factors such as fibrosis stage, previous treatment, HCV genotype, and baseline HCV viral load did not influence SVR12 rates in the four groups (P = 0.21). Hematological adverse events (AEs) were more common in the RBV group: anemia (P < 0.0001) and blood transfusion (P = 0.0001). CONCLUSION: SOF + NS5A inhibitors without RBV for 12 weeks constituted reliable therapy for recurrent HCV post-LT with an excellent SVR12 whatever the fibrosis stage, HCV genotype, and previous HCV treatment.

RESUMEN

BACKGROUND: A recurrence of hepatitis C virus (HCV) after liver transplantation affects survival in human immunodeficiency virus (HIV)/HCV coinfected patients. This study assessed the efficacy and safety of sofosbuvir (SOF)-based regimens in HIV/HCV coinfected patients after liver transplantation. METHODS: Twenty-nine HIV/HCV coinfected transplanted patients receiving tacrolimus-, cyclosporine-, or everolimus-based immunosuppressive therapy were enrolled in the Compassionate Use of Protease Inhibitors in Viral C Liver Transplantation cohort. Their antiviral treatment combined SOF, daclatasvir with or without ribavirin (n = 10/n = 6), or SOF, ledipasvir with or without ribavirin (n = 2/n = 11). RESULTS: The median delay between liver transplantation and treatment initiation was 37.5 months (interquartile range [IQR], 14.4-99.2). The breakdown of HCV genotypes was G1, 22 patients (75.9%); G3, 3 patients (10.3%); and G4, 4 patients (13.8%). The treatment indications were HCV recurrence (≥ F1 n = 23) or fibrosing cholestatic hepatitis (n = 6). Before starting SOF, the HCV viral load and CD4 count were 6.7 log10 IU/mL (IQR, 5.9-7.2) and 342 cells/mm (IQR, 172-483), respectively. At week 4, the HCV viral load was less than 15 IU/mL in 12 (42.9%) patients. The overall sustained virological response 12 was 96.6%. No significant drug-drug interactions were observed. CONCLUSIONS: SOF-based treatment regimens produced excellent results in HIV/HCV coinfected patients after liver transplantation, suggesting an important change in their prognosis.
