Aim Patients with type 2 diabetes mellitus (T2DM) represent a high-risk population for both cardiovascular diseases and severe coronavirus disease 2019 (COVID-19). Recent studies have reported interactions between statin treatment and COVID-19-related outcomes. The study reported here specifically assessed the association between routine statin use and COVID-19-related outcomes in inpatients with T2DM. Methods The Coronavirus–SARS-CoV-2 and Diabetes Outcomes (CORONADO) study was a nationwide observational study aiming to describe the phenotypic characteristics and prognosis of T2DM patients with COVID-19 admitted to 68 French hospitals between 10 March and 10 April 2020. The composite primary outcome comprised tracheal intubation and/or death within 7 and 28 days of admission. The association between statin use and outcomes was estimated by logistic regression analysis after applying inverse probability of treatment weighting (IPTW) using a propensity score-weighting approach. Results Of the 2449 patients with T2DM (881 women, 1568 men; aged 70.9 ± 12.5 years) suitable for analysis, 1192 (49%) were using statin treatment before admission. In unadjusted analyses, patients using statins had rates of the primary outcome similar to those of non-users within both 7 (29.8% vs 27.0%, respectively; P = 0.1338) and 28 days (36.2% vs 33.8%, respectively; P = 0.2191) of admission. However, mortality rates were significantly higher in statin users within 7 (12.8% vs 9.8%, respectively; P = 0.02) and 28 days (23.9% vs 18.2%, respectively; P < 0.001). After applying IPTW, significant associations were observed with statin use and the primary outcome within 7 days (OR [95% CI]: 1.38 [1.04–1.83]) and with death within both 7 (OR [95% CI]: 1.74 [1.13–2.65]) and 28 days (OR [95% CI]: 1.46 [1.08–1.95]). Conclusion Routine statin treatment is significantly associated with increased mortality in T2DM patients hospitalized for COVID-19.

Background: Lyme borreliosis (LB) is the most frequent vector-borne disease in France. Since 2009, surveillance of LB is conducted by a sentinel network of general practitioners (GPs). This system, in conjunction with the national hospitalisation database was used to estimate the incidence and describe the characteristics of LB in France.Aim: To describe the estimated incidence and trends in GP consultations and hospital admissions for LB in France and identify risk groups and high-incidence regions.Results: From 2011 to 2016, the mean yearly incidence rate of LB cases was 53 per 100,000 inhabitants (95% CI: 41–65) ranging from 41 in 2011 to 84 per 100 000 in 2016. A mean of 799 cases per year were hospitalised with LB associated diagnoses 2005–16. The hospitalisation incidence rate (HIR) ranged from 1.1 cases per 100,000 inhabitants in 2005 to 1.5 in 2011 with no statistically significant trend. We observed seasonality with a peak during the summer, important inter-regional variations and a bimodal age distribution in LB incidence and HIR with higher incidence between 5 and 9 year olds and those aged 60 years. Erythema migrans affected 633/667 (95%) of the patients at primary care level. Among hospitalised cases, the most common manifestation was neuroborreliosis 4,906/9,594 (51%).Conclusion: Public health strategies should focus on high-incidence age groups and regions during the months with the highest incidences and should emphasise prevention measures such as regular tick checks after exposure and prompt removal to avoid infection.

Background and Aims Inflammatory bowel diseases [IBD] are disabling disorders. The IBD-Disability Index [IBD-DI] was developed for quantifying disability in IBD patients but is difficult to use. The IBD-Disk is a visual adaptation of the IBD-DI. It has not been validated yet. The main objectives were to validate the IBD-Disk and to assess the clinical factors associated with a change in the score and its variability over time. Methods From May 2018 to July 2019, IBD patients from three university-affiliated hospitals responded twice to both IBD-Disk and IBD-DI at 3–12 month intervals. Validation included concurrent validity, reproducibility, and internal consistency. Mean IBD-Disk scores were compared according to clinical factors. Variability was assessed by comparing scores between baseline and follow-up visits. Results A total of 447 patients [71% Crohn’s disease, 28% ulcerative colitis] were included in the analysis at baseline and 265 at follow-up. There was a good correlation between IBD-Disk and IBD-DI [r = 0.75, p &lt;0.001]. Reproducibility was excellent [intra-class correlation coefficient = 0.90], as well as internal consistency [Cronbach’s α = 0.89]. The IBD-Disk was not influenced by IBD type but was associated with female gender and physician global assessment. Extra-intestinal manifestations, history of resection, elevated C-reactive protein and faecal calprotectin also tended to be associated with higher disability. The IBD-Disk score decreased in patients becoming inactive over time. Conclusions This study validated the IBD-Disk in a large cohort of IBD patients, demonstrating that it is a valid and reliable tool for quantifying disability for both CD and UC.

In patients with diabetes hospitalized for COVID-19 in CORONADO study, 2.8% had a newly discovered diabetes (NDD): mean age 60.2±12.5 years and HbA 1C 9.0±2.5 %. When compared with center, age and sex-matched patients with established type 2 diabetes, NDD was not significantly associated with a more severe COVID-19 prognosis.

Aim To investigate the association between routine use of dipeptidyl peptidase‐4 (DPP‐4) inhibitors and the severity of coronavirus disease 2019 (COVID‐19) infection in patient with type 2 diabetes in a large multicentric study. Materials and Methods This study was a secondary analysis of the CORONADO study on 2449 patients with type 2 diabetes (T2D) hospitalized for COVID‐19 in 68 French centres. The composite primary endpoint combined tracheal intubation for mechanical ventilation and death within 7 days of admission. Stabilized weights were computed for patients based on propensity score (DPP‐4 inhibitors users vs. non‐users) and were used in multivariable logistic regression models to estimate the average treatment effect in the treated as inverse probability of treatment weighting (IPTW). Results Five hundred and ninety‐six participants were under DPP‐4 inhibitors before admission to hospital (24.3%). The primary outcome occurred at similar rates in users and non‐users of DPP‐4 inhibitors (27.7% vs. 28.6%; p = .68). In propensity analysis, the IPTW‐adjusted models showed no significant association between the use of DPP‐4 inhibitors and the primary outcome by Day 7 (OR [95% CI]: 0.95 [0.77–1.17]) or Day 28 (OR [95% CI]: 0.96 [0.78–1.17]). Similar neutral findings were found between use of DPP‐4 inhibitors and the risk of tracheal intubation and death. Conclusions These data support the safety of DPP‐4 inhibitors for diabetes management during the COVID‐19 pandemic and they should not be discontinued.

Background Vaccination policy in France was previously characterised by the coexistence of eight recommended and three mandatory vaccinations for children younger than 2 years old. These 11 vaccines are now mandatory for all children born after 1 January 2018. Aim To study the French population’s opinion about this new policy and to assess factors associated with a positive opinion during this changing phase. Methods A cross-sectional survey about vaccination was conducted from 16 November–19 December 2017 among the GrippeNet.fr cohort. Data were weighted for age, sex and education according to the French population. Univariate and multivariate analyses were performed to identify factors associated with a favourable opinion on mandatory vaccines’ extension and defined in the ‘3Cs’ model by the World Health Organization Strategic Advisory Group of Experts working group on vaccine hesitancy. Results Of the 3,222 participants (response rate 50.5%) and after adjustment, 64.5% agreed with the extension of mandatory vaccines. It was considered a necessary step by 68.7% of the study population, while 33.8% considered it unsafe for children and 56.9% saw it as authoritarian. Factors associated with a positive opinion about the extension of mandatory vaccines were components of the confidence, complacency and convenience dimensions of the ‘3Cs’ model. Conclusions In our sample, two thirds of the French population was in favour of the extension of mandatory vaccines for children. Perception of vaccine safety and benefits were major predictors for positive and negative opinions about this new policy.

Aims  Risk stratification of sudden cardiac arrest (SCA) in Brugada syndrome (Brs) remains the main challenge for physicians. Several scores have been suggested to improve risk stratification but never replicated. We aim to investigate the accuracy of the Brs risk scores. Methods and results  A total of 1613 patients [mean age 45 ± 15 years, 69% male, 323 (20%) symptomatic] were prospectively enrolled from 1993 to 2016 in a multicentric database. All data described in the risk score were double reviewed for the study. Among them, all patients were evaluated with Shanghai score and 461 (29%) with Sieira score. After a mean follow-up of 6.5 ± 4.7 years, an arrhythmic event occurred in 75 (5%) patients including 16 SCA, 11 symptomatic ventricular arrhythmia, and 48 appropriate therapies. Predictive capacity of the Shanghai score (n = 1613) and the Sieira (n = 461) score was, respectively, estimated by an area under the curve of 0.73 (0.67–0.79) and 0.71 (0.61–0.81). Considering Sieira score, the event rate at 10 years was significantly higher with a score of 5 (26.4%) than with a score of 0 (0.9%) or 1 (1.1%) (P &lt; 0.01). No statistical difference was found in intermediate-risk patients (score 2–4). The Shanghai score does not allow to better stratify the risk of SCA. Conclusions  In the largest cohort of Brs patient ever described, risk scores do not allow stratifying the risk of arrhythmic event in intermediate-risk patient.
