    ABSTRACT: Background and aims: Data on the efficacy and safety of seasonal influenza vaccines in patients with inflammatory bowel disease (IBD) remain scarce. The aim of the study was to evaluate the impact of immunosuppressive (IS) therapeutics on serological response to 2-year influenza vaccination in IBD adults. Methods: A multicenter prospective study performed in 255 IBD adults (18-64 years) receiving the trivalent influenza vaccine for years 2009-2010 and 2010-2011. Haemagglutination inhibition (HI) titres assessed before, 3 weeks and 6 months post-vaccination. Results: At inclusion, 31 patients had no IS (Group A), 77 IS without anti-TNF (Group B) and 117 anti-TNF with or without IS (Group C). Three weeks after the first vaccination, rates of seroprotection were 77%, 75% and 66% for A/H1N12007 strain (p=0.35), 77%, 68% and 52% for A/H3N2 strain (p=0.014) and 97%, 96% and 95% for B strain (p=0.99) in groups A, B, and C, respectively. Seroconversion rates for A/H1N12007 strain (67%, 64%, 54%; p=0.28), A/H3N2 strain (63%, 50%, 41%; p=0.074) and B strain (63%, 76%, 60%; p=0.078) were not significantly different according to treatment group. At 6 months after vaccination, seroprotection rates were lower in Group C compared to Group A and B. Comparable results were observed for the second year of vaccination. No impact on Harvey-Bradshaw and Mayo scores has been detectedConclusions:Influenza vaccine yielded high seroprotection rates in IBD patients. Persistence of seroprotection was lower in patients with, Number NCT01022749.

    ABSTRACT: Introduction In France, vaccination against human papilloma virus (HPV) was recommended in 2007 for all 14-year-old girls as well as "catch-up" vaccination for girls between 15-23 years of age either before or within one year of becoming sexually active. We evaluated the vaccine coverage according to the eligibility for vaccination in a sample of young girls aged 14 to 23 years, who were seen in general practices. Patients and methods A survey was proposed to 706 general practitioners (GPs) and carried out from July to September 2010. GPs, also called "family doctor", are physicians whose practice is not restricted to a specific field of medicine but instead covers a variety of medical problems in patients of all ages. Each participating GP included, retrospectively, the last female patient aged 14-17 years and the last female patient aged 18-23 years whom he had seen. A questionnaire collected information regarding the GP and the patients' characteristics. The vaccine coverage was determined according to the eligibility for vaccination, i.e. the coverage among younger women (14-17) and among those sexually active in the second age range (18-23). Sexual activity status was assessed by GP, according to information stated in the medical record. Results The 363 participating physicians (response rate 51.4%) included 712 patients (357 in the 14- to 17-year-old group and 355 in the 15- to 23-year-old group) in their responses. The rate of the vaccination coverage in the 14- to 17-year-old group was 55%. Among the girls in the 18- to 23-year-old group, 126 were eligible, and their vaccination coverage rate was 82%. The evaluation of the eligibility by the GPs was incorrect in 36% of the cases. Of the 712 patients, 6% of the girls had been vaccinated without a need for the vaccination, and 26% of the girls had not been vaccinated, although they needed to be vaccinated. Discussion Regarding the vaccine uptake, vaccination at the age of 14 was not as effective as vaccinating the older population for which vaccination was indicated as a catch-up program, based on sexual history. However, in more than one-third of the older population, difficulties remained regarding the determination of eligibility, according to the sexual history of the patient.

    ABSTRACT: To assess the opinions of the French general population about seasonal influenza vaccination three years after the A(H1N1)pdm 09 pandemic and identify factors associated with a neutral or negative opinion about this vaccination. The study was conducted using data collected from 5374 participants during the 2012/2013 season of the study. The opinion about seasonal influenza vaccination was studied on three levels ("positive", "negative" or "neutral"). The link between the participant's characteristics and their opinion regarding the seasonal influenza vaccination were studied using a multinomial logistic regression with categorical variables. The "positive" opinion was used as the reference for identifying individuals being at risk of having a "neutral" or a "negative" opinion. Among the participants, 39% reported having a positive opinion about seasonal influenza vaccine, 39% a neutral opinion, and 22% a negative opinion. Factors associated with a neutral or negative opinion were young age, low educational level, lack of contact with sick or elderly individuals, lack of treatment for a chronic disease and taking a homeopathic preventive treatment. These results show that an important part of the French population does not have a positive opinion about influenza vaccination in France. Furthermore, it allows outlining the profiles of particularly reluctant individuals who could be targeted by informative campaigns. Copyright © 2015. Published by Elsevier Ltd.

    ABSTRACT: The ongoing influenza epidemic is characterized by intense activity with most influenza infections due to the A(H3N2) viruses. Using the screening method, mid-season vaccine effectiveness (VE) in preventing influenza-like illness in primary care was estimated to 32% (95% CI; 23 to 40) among risk groups and was 11% (95% CI; -4 to 23) among the elderly (≥65 years). The VE in ≥65 years was the lowest estimate regarding the four previous seasonal influenza epidemics.

    ABSTRACT: In 2012 and 2013, a cross-sectional survey was conducted in women visiting a general practitioner for a urinary tract infection (UTI) to i) describe the patterns of antibiotic resistance of Enterobacteriaceae involved in community-acquired UTIs and ii) identify the factors associated with UTIs due to a multi-drug-resistant Enterobacteriaceae (MDREB). Urine analyses were performed systematically for all adult women presenting with signs of UTI. Characteristics of women with UTI due to MDREB were compared to those with UTI due to non-MDREB. Weighted logistic regressions were performed to adjust for the sampling design of the survey. Significant factors associated with MDREB included the use of penicillin by the patient in the last three months (OR = 3.1; [1.2-8.0]); having provided accommodation in the previous 12 months to a resident from a country at high risk for drug resistance (OR = 4.0; [1.2-15.1]); and the consumption of raw meat within the previous three months (OR = 0.3; [0.1-0.9]). In the community, antibiotic use and exposure to a person returning from an area with a high risk of drug resistance are associated with UTIs due to MDREB. The potentially protective role of raw meat consumption warrants further study. Copyright © 2015 The British Infection Association. Published by Elsevier Ltd. All rights reserved.

    ABSTRACT: To measure the frequency and nature of wounds in patients treated in general practice and to describe the patients' tetanus vaccination status and the sources providing information about this status. A descriptive, prospective, week-long, national electronic survey was conducted among general practitioners within the Sentinelles network. The participation rate was 12.6% (95% confidence interval [CI], 10.6%-14.6%; 130 general practitioners): 197 patients with wounds were reported, and 175 of them were described. Wound frequency was 1.4 (95% CI, 1.2-1.6) per 100 consultations. These wounds had an acute character in 76 (95% CI, 69.7-82.3) of cases, were mostly of traumatic origin (54.8% of cases; 95% CI, 47.5%-62.1%), were more than 24 hours old (67.1%; 95% CI, 59.1%-75.1%), and were clean, without bone and/or muscle decay (94%; 95% CI, 90.5%-97.5%). Vaccination status was known for 71 (95% CI, 64-78) patients. According to the 2013 immunization schedule, 21% (95% CI, 13.9%-28.1%) of the patients had not updated their vaccinations, mostly among the patients older than 75 years. This survey describes in detail the wounds treated in general practice in France and the associated patients' immunization status. It also shows how difficult it is for general practitioners to assess the risk of contracting tetanus and the disease's development. It highlights as well the fact that the ideal solution to assess tetanus risk is an up-to-date immunization schedule.

    ABSTRACT: To estimate the prevalence of GP (general practitioner) patients performing ISC (intermittent self-catheterization), to describe GP and patient knowledge about ISC and to assess the patients' quality of life. A cross-sectional study was conducted in metropolitan France between November 2012 and September 2013 with French Sentinelles GPs and their patients (≥18 years) performing ISC. Linear regression models assessed independent associations between quality of life scores (Qualiveen and SF-12 scores) and patients' characteristics. The prevalence of ISC performers was estimated to be 61.7 (95% confidence interval [CI] = 61.0-62.4) of 100,000 inhabitants. Patients were males in 58.8% of cases and 53.8 years of age on average. They performed 4.84 catheterizations per day for 10.5 years. Over 1 year, there were 118 (55.1%) cases of patient-reported urinary incontinence (UI) and 158 (63.3%) cases of patient-reported urinary tract infection (UTI). Symptomatic UTIs were treated with antibiotics in 79.7% of cases. The average Qualiveen score was 1.38 (95%CI: 1.23-1.53). The average SF-12 Physical Component Score (PCS) and Mental Component Score (MCS) were 38.6 (95%CI: 36.8-40.4) and 46.4 (95%CI: 44.3-48.5), respectively. According to multivariate analysis, a poorer Qualiveen score and constipation reduced the PCS and a urinary medication prescription reduced the MCS. A poorer Qualiveen score was also associated with UI and UTI on bivariate analysis. ISC seems to be significant in French general practice whereas practical skills remain heterogeneous. UI, UTI, and constipation are recurrent issues among ISC performers that significantly decrease their quality of life. Education and adapted guidelines for GP guidance could improve these patients' conditions. Neurourol. Urodynam. 9999:1-7, 2015. © 2015 Wiley Periodicals, Inc. © 2015 Wiley Periodicals, Inc.

    ABSTRACT: In a context of controversy about influenza antiviral treatments, this study assessed primary health care physicians' prescription of neuraminidase inhibitors (NIs) in France during pandemic and seasonal influenza between 2009 and 2013. This observational study, using data recorded in three national databases, estimated the rate of NIs' prescription among influenza like-illness (ILI) patients seen in GPs' and paediatricians' consultations, and determined factors associated with this prescription according to a multivariate analysis. NIs' delivery by pharmacists was also evaluated. Rates of NIs' prescription were estimated to 61.1% among ILI patients with a severe influenza risk factor seen in GPs' consultation during the A(H1N1)pdm2009 pandemic versus an average rate of 25.9% during the three following seasonal influenza epidemics. Factors associated with NIs' prescription were a chronic disease in patients under 65 years (OR, 14.85; 95%CI, 13.00-16.97) and in those aged 65 and older (OR, 7.54; 5.86-9.70), an age ≥ 65 years in patients without chronic disease (OR, 1.35; 1.04-1.74), a pregnancy (OR, 10.63; 7.67-15.76), obesity (OR, 4.67; 3.50-6.22), and a consultation during the pandemic A(H1N1)pdm2009 (OR, 3.19; 2.93-3.48). The number of antiviral treatments delivered by pharmacists during the A(H1N1)pdm2009 pandemic was 835 per 100 000 inhabitants, and an average of 275 per 100 000 inhabitants during the three following seasonal influenza epidemics. Although physicians seem to follow the recommended indications for NIs in primary health care practice, this study confirms the low rate of NIs prescription to ILI patients with a severe influenza risk factor, especially during seasonal epidemics.

    ABSTRACT: When a hospitalisation is required in France, the general practitioner has the choice between public or private hospitals. The reasons for this choice are poorly known. All the cases of hospitalisation requirement reported between 1997 and 2001 by the general practitioners involved in the Réseau Sentinelles(®) were included in this study. The cardiovascular reasons were extracted from all these declarations. Factors influencing the general practitioners' choice between public and private sector were assessed by using logistic regression. During the study period, 45,960 cases of hospitalisation requirement were reported. Amongst these cases, 4475 (10.8%) were made for clearly defined cardivoascular diseases (cardiac failure 38.0%, coronary heart disease 24.7%, atrial fibrillation 11.7%, pulmonary embolism 8.4%, hypertension 3.6%, pericarditis 1.6%, cardiovascular check-up 1.5%). Referrals to private sector depended on the reason for hospitalisation, cardiovascular check-up being the reasons the most referred to a private institution (33.8% of patients) and cardiac insufficiency the less referred to private institution (17.2% of patients). Referral to private sector was also associated with physician (patient's usual general practitioner) and consultation (consultation outside of a context of emergency) characteristics. Whether patients suffering from cardiovascular diseases are sent to a public or private sector is not completely haphazard. Further analyses are needed in the context of new French health policies.

    ABSTRACT: Background: Recent studies have shown a decrease in the incidence of herpes zoster (HZ) among human immunodeficiency virus (HIV)-infected patients since the combined antiretroviral therapy (cART) era, but more data are needed on a possible increase in the risk early after cART initiation. Methods: We studied HZ incidence and risk factors among patients followed in the French Hospital Database on HIV (FHDH) between 1992 and 2011. Standardized incidence ratios (SIRs) were used for comparison with the general population between 2005 and 2008. The risk of HZ following cART initiation (0-5 and ≥6 months) was studied with Poisson regression models. Results: A total of 7167 cases of incident HZ were diagnosed among 91 044 individuals (583 125 person-years [PY]). The incidence declined significantly, from 2955 per 100 000 PY in 1992-1996 to 628 per 100 000 PY in 2009-2011. This decline was mainly explained by cART (relative risk [RR], 0.60; 95% confidence interval {CI}, .57-.64). The risk of HZ was associated with low CD4 cell counts, high HIV RNA levels, low CD4/CD8 ratios, and prior AIDS. Compared to the general population, the risk of HZ was higher in HIV-infected patients (overall SIR, 2.7; 95% CI, 2.6-2.9), particularly those aged 15-44 years (SIR, 4-6). In ART-naive patients, a moderate increase in the HZ risk was observed during the first 6 months of cART, with a peak at 3 months (RR, 1.47; 95% CI, 1.26-1.73), a finding that disappeared after adjustment for the current CD4 cell count (RR, 1.03; 95% CI, .81-1.32). Conclusions: The risk of HZ has declined markedly among HIV-infected patients in the cART era, but remains 3 times higher than in the general population. The risk increases moderately during the first 6 months of cART.

    ABSTRACT: SUMMARY A better understanding of physician practices in requesting stool samples for patients with acute gastroenteritis (AG) is needed to more accurately interpret laboratory-based surveillance data. A survey was conducted in General Practitioners (GPs) between August 2013 and July 2014 to estimate the proportion of stool samples requested for patients with AG and to identify factors associated with GP requests for a stool sample. National health insurance (NHI) data together with surveillance data from a French Sentinel GP network were also used to estimate the proportion of stool samples requested. This proportion was estimated at 4·3% in the GP survey and 9·1% (95% confidence interval 8·7-9·6) using NHI data. Multivariate analysis indicated that the ratio of stool samples requested was almost five times higher in patients with bloody diarrhoea and 10-20 times higher in patients with a long duration of illness before consultation. Laboratory-based surveillance data underestimates the actual burden of disease as fewer than one in 10 AG cases consulting their GP will be requested to submit a stool sample for laboratory testing. This underestimation varies by pathogen as stool samples are more frequently requested for severe illness.

    ABSTRACT: Background General Practitioners (GPs) play a central role in suicide prevention. This study aims to compare the characteristics of individuals who attempt suicide to those who complete suicide in a same primary care setting. Methods We compared the characteristics and GP׳s management of all patients with attempted (N=498, SA) or completed suicide (N=141, SC) reported to the GPs׳ French Sentinelles surveillance system (2009–2013). Results Compared to patients who attempted suicide, those who completed suicide were more likely to be male, older and to have used a more lethal method; for men they were less likely to have a history of previous suicide attempt and prior contacts with their GP. In terms of GPs׳ management, we found no differences between the SA and SC groups in the identification of psychological difficulties and in the care, but GPs were more likely to provide psychological support to the SA group. During the last consultation, the SC group expressed suicidal ideas more frequently than the SA group (26.7% vs. 14.8%, p<0.01), only for women. Limitations The network may have missed cases and selected more serious SA. Conclusions Individuals who commit suicide differ from those who attempt suicide in terms of demographic characteristics and by sex, of history of suicide attempt, previous contact and expressed suicidal ideas. We show that GPs do not act more intensively with patients who will commit suicide, as if they do not foresee them. Current prevention programs particularly in primary care should be tailored.

    ABSTRACT: Varicella can be severe in adults. When universal vaccination is not adopted, post-exposure prophylaxis has been recommended in adults with uncertain history of varicella to reduce the burden of the disease in adults, however its impact is not quantified. We developed a Bayesian probabilistic framework to estimate the impact of post-exposure prophylaxis in adults. We hypothesized that post-exposure vaccination would be proposed only after varicella exposure in close relatives. Information regarding the nature of the culprit exposure was obtained from a sample of 221 adult varicella cases. The lifelong probability that adults aged 18 would be infected with varicella was determined using data from the French Sentinelles surveillance network. Estimates of post-exposure vaccination efficacy were then used to compute the number of cases and hospitalizations prevented in adults. Familial exposure to varicella was reported by 81 adult cases out of 221. The probability of infection after exposure was 32%, so that six exposures on average were necessary to explain the observed cumulated lifetime incidence of varicella in non-immune 18 years old and over adults. Among the 35% of the 18 years old population with uncertain history of varicella, 11% would truly be non-immune. Post-exposure vaccination would prevent 26% of the cases (13 cases prevented per 100,000 adults per year) and 31% of the hospitalizations (0.2 hospitalizations prevented per 100,000 adults per year) if vaccination acceptance was 70%. An average of 16 adults would be vaccinated to avert one varicella case. Post-exposure vaccination is associated with a substantial decrease in the burden of the disease in adults in a country where universal vaccination is not recommended. This quantitative information may help inform professionals to uphold the recommendation. Copyright © 2014. Published by Elsevier Ltd.

    ABSTRACT: Introduction: The purpose of this study was to estimate the prevalence of monoclonal immunoglobulin (MIg) among patients with systemic sclerosis (SSc) according to the capillary electrophoresis or immunofixation method of detection and to search for any related clinical correlations. Patients and methods: Retrospective multicenter comparison of capillary electrophoresis and immunofixation results in SSc patients and of the characteristics of patients with and without MIg. Results: The study included 244 SSc patients (216 women and 28 men, mean age: 55±14 years). Median time since SSc diagnosis was 51 months [0-320]; disease was diffuse in 48% of cases. Ten percent of patients had cancer, including Waldenström macroglobulinemia (n=1) and multiple myeloma (n=3). Capillary electrophoresis showed a γ-globulin anomaly in 41% of cases, and immunofixation in 18%: MIg (13.5%) and restriction of heterogeneity (4.5%). Capillary electrophoresis failed to detect 60% of the 33 MIg patients. Measurable MIg concentrations were obtained from 7 patients. MIg patients were significantly older at SSc diagnosis than those without MIg (p=0.002), had a lower diffusing capacity (p=0.002), a higher prevalence of pulmonary hypertension and cancer (p=0.002) and were more frequently positive for anti-mitochondrial and anti-beta2-glycoprotein-I antibodies (p=0.03 and p=0.02, respectively). Multivariate analyses showed that only age at test [hazard ratio 1.03 (95% CI, 1.00-1.07, p=0.04)] and presence of cancer [hazard ratio 4.46 (95% CI, 1.6-12.4, p=0.004)] were associated with MIg. Conclusion: Immunofixation detected a high prevalence of MIg among SSc patients especially in patients aged 50-years or older. MIg was not detected by the standard capillary electrophoresis in 60% of cases and was significantly associated with cancer.

    ABSTRACT: Background Data describing the epidemiology and management of viral acute diarrhea (AD) in adults are scant. The objective of this study was to identify the incidence, clinical characteristics, management and risk factors of winter viral AD in adults.Methods The incidence of AD in adults during two consecutive winters (from December 2010 to April 2011 and from December 2011 to April 2012) was estimated from the French Sentinelles network. During these two winters, a subset of Sentinelles general practitioners (GPs) identified and included adult patients who presented with AD and who filled out a questionnaire and returned a stool specimen for virological examination. All stool specimens were tested for astrovirus, group A rotavirus, human enteric adenovirus, and norovirus of genogroup I and genogroup II. Age- and sex-matched controls were included to permit a case¿control analysis with the aim of identifying risk factors for viral AD.ResultsDuring the studied winters, the average incidence of AD in adults was estimated to be 3,158 per 100,000 French adults (95% CI [2,321 ¿ 3,997]). The most reported clinical signs were abdominal pain (91.1%), watery diarrhea (88.5%), and nausea (83.3%). GPs prescribed a treatment in 95% of the patients with AD, and 80% of the working patients with AD could not go to work. Stool examinations were positive for at least one enteric virus in 65% (95% CI [57 ¿ 73]) of patients with AD with a predominance of noroviruses (49%). Having been in contact with a person who has suffered from AD in the last 7 days, whether within or outside the household, and having a job (or being a student) were risk factors significantly associated with acquiring viral AD.Conclusions During the winter, AD of viral origin is a frequent disease in adults, and noroviruses are most often the cause. No preventable risk factor was identified other than contact with a person with AD. Thus, at the present time, reinforcement of education related to hand hygiene remains the only way to reduce the burden of disease.

    ABSTRACT: Background: The Internet is becoming more commonly used as a tool for disease surveillance. Similarly to other surveillance systems and to studies using online data collection, Internet-based surveillance will have biases in participation, affecting the generalizability of the results. Here we quantify the participation biases of Influenzanet, an ongoing European-wide network of Internet-based participatory surveillance systems for influenza-like-illness. Methods: In 2011/2012 Influenzanet launched a standardized common framework for data collection applied to seven European countries. Influenzanet participants were compared to the general population of the participating countries to assess the representativeness of the sample in terms of a set of demographic, geographic, socio-economic and health indicators. Results: More than 30,000 European residents registered to the system in the 2011/2012 season, and a subset of 25,481 participants were selected for this study. All age classes (10 years brackets) were represented in the cohort, including under 10 and over 70 years old. The Influenzanet population was not representative of the general population in terms of age distribution, underrepresenting the youngest and oldest age classes. The gender imbalance differed between countries. A counterbalance between gender-specific information-seeking behavior (more prominent in women) and Internet usage (with higher rates in male populations) may be at the origin of this difference. Once adjusted by demographic indicators, a similar propensity to commute was observed for each country, and the same top three transportation modes were used for six countries out of seven. Smokers were underrepresented in the majority of countries, as were individuals with diabetes; the representativeness of asthma prevalence and vaccination coverage for 65+ individuals in two successive seasons (2010/2011 and 2011/2012) varied between countries. Conclusions: Existing demographic and national datasets allowed the quantification of the participation biases of a large cohort for influenza-like-illness surveillance in the general population. Significant differences were found between Influenzanet participants and the general population. The quantified biases need to be taken into account in the analysis of Influenzanet epidemiological studies and provide indications on populations groups that should be targeted in recruitment efforts.
