Evaluation of HIV antiretroviral treatment adherence in 2019 using anonymized data from the French national health insurance claims data base: The COCOVIH study.

OBJECTIVE: Adherence to antiretroviral treatment (ART) plays a key role in achieving viral suppression in people living with HIV. We aimed to quantify ART adherence in the entire French HIV-infected population treated in 2019 and to determine factors of influence. METHODS: People living with HIV were identified using HIV diagnosis according to International Statistical Classification of Diseases and Related Health Problems, Tenth Revision criteria, HIV-specific laboratory tests, and prescription of antiretrovirals in 2019. Adherence was measured using the medication possession ratio (MPR; actual divided by theoretical number of tablets). Variables of interest included sex, age, type of ART, relevant comorbidities, and receiving supplementary universal health coverage for low-income citizens (CMUc). RESULTS: Of the n = 211 124 people living with HIV identified between 2006 and 2019, we included n = 140 607 on ART with two or more prescription fills in 2019 in this analysis. In total, 87.5% of people living with HIV were receiving ART in 2019. Mean ± standard deviation MPR was 82.5 ± 22.7%; 57% of people living with HIV had an MPR ≥90%, and 12.7% had an MPR <50%. Those with an MPR ≥90% significantly differed between males and females (59.1% and 52.8%, respectively; p < 0.001), and between CMUc recipients and non recipients (54.1% and 57.6%, respectively; p < 0.001). MPR ≥90% rate was lower for those with chronic nephropathy (50.2%), renal failure (46.6%), and tuberculosis (50.1%), and for those using psychoactive substances (52.3%). Factors associated with MPR ≥90% in multivariable analysis were older age, male sex, not receiving CMUc, more recent HIV diagnosis, and triple (vs. dual) ART. CONCLUSION: In 2019, the average MPR in people living with HIV was 82.5% according to the comprehensive French health care database. Besides sociodemographic variables such as older age, male sex, and not being a CMUc recipient (i.e. of low socioeconomic status), more recent HIV diagnosis and triple therapy were independently associated with better adherence, possibly reflecting advances in ART tolerability and dosing.

Epidemiology of myasthenia gravis in France: A retrospective claims database study (STAMINA).

BACKGROUND: The objectives of this observational study were to report the incidence and prevalence of myasthenia gravis (MG) in France, describe patients' characteristics and treatment patterns, and estimate mortality. METHODS: A historical cohort analysis was performed using the French National Health Data System (SNDS) database between 2008 and 2020. Patients with MG were identified based on ICD-10 codes during hospitalization and/or long-term disease (ALD) status, which leads to a 100% reimbursement for healthcare expenses related to MG. The study population was matched to a control group based on age, sex and region of residence. RESULTS: The overall incidence of MG was estimated at 2.5/100,000 in 2019 and the overall prevalence at 34.2/100,000. The mean age was 58.3 years for incident patients and 58.6 for prevalent patients. Among patients with MG, 57.1% were women. In the first year after identification of MG, acetylcholinesterase inhibitors were the most commonly used treatments (87.0%). Corticosteroids were delivered to 58.3% of patients, intravenous immunoglobulin to 34.4%, and azathioprine to 29.9%. Additionally, 8% of patients underwent thymectomy. The proportions of patients with exacerbations and crises were 59.7% and 13.5% respectively in the first year after MG identification. All-cause mortality was significantly higher in patients with MG compared to matched controls (HR=1.82 (95% CI [1.74;1.90], P<0.0001)). CONCLUSION: In this study, the incidence and prevalence of MG estimated in France were found to be higher than previously reported. Most exacerbations and crises occurred within the first year after MG identification. MG was associated with increased mortality compared to a control population matched on age, gender, and geographical region.

Progesterone levels on the human chorionic gonadotropin trigger day affect the pregnancy rates for embryos transferred at different stages of development in both general and selected IVF/ICSI populations.

BACKGROUND: Two meta-analyses have shown that pregnancy and birth rates are significantly higher after blastocyst transfer than after cleaved embryo transfer. Other studies have revealed that a serum progesterone level > 1.5 ng/ml on the trigger day is responsible for premature luteinization and is associated with a low pregnancy rate. The objectives of this retrospective study were to determine whether blastocyst transfer gave higher pregnancy rates than cleaved embryo transfer at day 3 in both the general and selected IVF/ICSI populations, and whether the serum progesterone level influenced the pregnancy rate. METHOD: We studied IVF/ICSI cycles with GnRH antagonist - FSH/hMG protocols in a general population (n = 1210) and a selected "top cycle" population (n = 677), after blastocyst transfer on day 5 or cleaved embryo transfer on day 3. The selected couples had to meet the following criteria: female age < 35, first or second cycle, and one or two embryos transferred. We recorded predictive factors for pregnancy and calculated the progesterone to oocyte index (POI), the progesterone:estradiol ratio (P:E2 ratio), and the progesterone to follicle (> 14 mm) index (PFI). RESULTS: In the general population, the clinical pregnancy rate was significantly higher after blastocyst transfer (33.3%) than after cleaved embryo transfer (25.3%; p <  0.01); the same was true for the birth rate (32.1 and 22.8%, respectively, p <  0.01). The differences between blastocyst and embryo transfer groups were not significant in the selected population (respectively 35.7% vs. 35.8% for the clinical pregnancy rate, and 33.9 and 34.9% for the birth rate). The serum progesterone levels on the eve of the trigger day and on the day itself were significantly lower in the pregnant women (p <  0.01). We found a serum progesterone threshold of 0.9 ng/ml, as also reported by other researchers. The POI and the PFI appear to have predictive value for cleaved embryos transfers. CONCLUSIONS: Blastocyst transfers were associated with higher clinical pregnancy and birth rates than cleaved embryo transfers in a general population but not in a selected population. The serum progesterone levels on the eve of the trigger day and on the day itself predicted the likelihood of pregnancy.

Toxigenic Clostridium difficile carriage in general practice: results of a laboratory-based cohort study.

OBJECTIVES: Reported rates of community-acquired Clostridium difficile infections (CDIs) have been increasing. However, the true burden of the disease in general practice is unknown in France. Our objective was to determine the incidence of toxigenic C. difficile carriage and the percentage of stool samples prescribed by general practitioners (GPs) which contained free C. difficile toxins. METHODS: During an 11-month period, all stool samples submitted for any enteric pathogen detection to 15 different private laboratories in Paris and the surrounding areas were tested for C. difficile, irrespective of the GPs' request. A clinical questionnaire was completed for each patient. Stool samples were screened using a rapid simultaneous glutamate dehydrogenase and toxins A/B detection test: any positive result (glutamate dehydrogenase or toxin) was further confirmed by the stool cytotoxicity assay (CTA) on MRC-5 cells and by toxigenic culture (TC) at a central laboratory. The C. difficile isolates were characterized by PCR ribotyping. RESULTS: A total of 2541 patients (1295 female, 1246 male) were included. The incidences of patients with a positive toxigenic culture and a positive CTA were 3.27% (95% CI 2.61%-4.03%) and 1.81% (95% CI 1.33%-2.41%), respectively. GPs requested C. difficile testing in only 12.93% of the stool samples, detecting 52.30% of all TC-positive patients. The 83 toxigenic C. difficile strains belonged to 36 different PCR ribotypes. CONCLUSIONS: Toxigenic C. difficile carriage is frequent in general practice but remains under-recognized. It may affect young patients without previous antimicrobial therapy or hospitalization.

Outcomes and treatment management of a French cohort suffering from multiple sclerosis: A retrospective epidemiological study.

BACKGROUND: Despite a recent interest in Real World Data, such studies are scarce in multiple sclerosis (MS) disease. The objective was to describe the patients, disease progression and use of DMDs in France and compare clinical effectiveness of first-line injectable DMDs. METHODS: We conducted a retrospective multicenter study in France, using data collected by 11 expert centers with the EDMUS software. RESULTS: Overall, 15,039 French MS patients were followed for a mean of 11.5 years. Mean age at start of disease was 32 years and 74% were women. After the disease onset, median time to reach EDSS 3 was 11 years and 51.8% of patients were relapse-free 2 years after the disease's onset. The mean delay between onset of disease and initiation of treatment was 5.7 ±â€¯6.9 years. Over time, it decreased from 8.8 ±â€¯7.8 to 0.7 ±â€¯0.7 years for initiation of treatment before 2000 vs. after 2010, respectively. Two years after the initiation of treatment, the persistence rate of injectable disease modifying drugs (DMDs) was 60.7%. The effectiveness of these drugs were quite similar. CONCLUSION: This study brings new insight on the natural history of MS and the use and effectiveness of injectable DMDs in this condition.

DEPIVIH 2: Use of three HIV testing methods in French primary care settings - ELISA laboratory screening versus two rapid point-of-care HIV tests.

OBJECTIVE: The primary endpoint was to evaluate the use of HIV testing methods by French primary care providers: Elisa laboratory screening, instant result HIV diagnostic test and rapid result HIV diagnostic test. The secondary endpoints were the population screening rate of unknown HIV status consulting during the study period, reasons for screening and for choosing the specific screening method, the investigators' satisfaction with the rapid diagnostic test (RDT) and problems encountered. PATIENTS AND METHODS: National prospective interventional study with French family physicians (FP) from December 2013 to December 2014. FPs enrolled all consenting adults consulting for an HIV screening test during a 6-month period: the choice was an Elisa laboratory test or one of the two RDTs. RESULTS: During the study period, 43 FPs included 981 patients. HIV screening was performed for the first time for 31.6% of patients; 767 (78.2%) Elisa laboratory test prescriptions and 214 (21.8%) RDTs were performed, leading to a screening rate of 1.3%. For 120 (15.7%) of the Elisa laboratory tests, the result was not reported and six RDTs were not valid. Nine patients were diagnosed as HIV-infected (0.9%): five with Elisa laboratory test and four with RDT. Almost 90% of FPs were willing to keep on using RDTs in their daily practice. CONCLUSION: In general practice, RDTs may be an important additional tool to traditional HIV screening. They could account for one in five tests prescribed in this context.

Excess mortality between 2007 and 2014 among patients with Clostridium difficile infection: a French health insurance database analysis.

BACKGROUND: The impact of Clostridium difficile infection (CDI) on mortality is controversial. AIM: To assess excess mortality due to CDI in France. METHOD: Two cohorts of patients with CDI and a cohort of matched controls were extracted from a 1% representative sample of subjects covered by the general health insurance system in France (Echantillon Généraliste de Bénéficiaires database, 660,000 patients). The CDI patients were hospitalized with CDI as a principal diagnosis or an associated diagnosis between 2007 and 2014, but not in 2006. Controls were patients hospitalized between 2007 and 2014 but not hospitalized with CDI between 2006 and 2014. The one-year incidence of deaths between 2007 and 2014 was estimated and compared with that of a propensity score (PS)-matched control group with no CDI (two controls per case). The PS was calculated with the following variables: age; sex; Charlson Comorbidity Index score; duration of stay; year of index stay; and main comorbidities. Cox and Poisson models were used to estimate the increased risk of death while adjusting for PS. Sensitivity analyses (timeframe, diarrhoea, recurrent hospitalization for CDI) were used to explore the robustness of the results. FINDINGS: In total, 482 patients who had been infected with C. difficile were matched with 964 controls. A significantly higher risk of death was observed among the subjects with CDI, with a non-adjusted hazard ratio of 1.65 [95% confidence interval (CI) 1.33-2.04] and an adjusted ratio of 1.58 (95% CI 1.27-1.97). The adjusted relative risk of death was 1.78 (95% CI 1.18-2.70]) at 28 days, 1.52 (95% CI 1.17-1.98) at three months, 1.52 (95% CI 1.20-1.93) at six months and 1.64 (95% CI 1.32-2.03) at 12 months. Sensitivity analyses produced similar results; the hazard ratio ranged from 1.53 to 1.86, and was always statistically significant. CONCLUSION: CDI is responsible for excess mortality after taking age, sex, comorbidities and length of hospital stay into account.

[Which ovarian stimulation to which women: The polycystic ovary syndrome (PCOS)]. / Quelles stimulations pour quelles femmes : le syndrome des ovaires polykystiques (SOPK).

Polycystic ovarian syndrome (PCOS) is a frequent pathology in the young woman, linking infertility to a metabolic disease. Initial support will include a plan (in the case of overweight or obesity) to lose at least 5 to 10% of the weight. Subsequently, clomiphene citrate is the first treatment for ovulation induction with pregnancy rates of 40 to 80% after 6 cycles. If there is resistance to clomiphene citrate, the choice will be between the ovarian drilling (50-60% of pregnancy in the year following, including the half spontaneous) or ovarian stimulation with gonadotropins. The risk of ovarian stimulation in these women is hyperstimulation and multiple pregnancies. We also discuss the place of the GnRH pulsatile administration, insulin-sensitizers, in vitro fertilization and in vitro maturation in these women. Once infertility support, these women should be long-term followed because of the neoplasic and cardiovascular risks they present.

[Costs of healthcare resource consumption after a myocardial infarction in France: An estimate from a medicoadministrative database (GSB)]. / Coût des consommations de soins après un infarctus du myocarde en France : une estimation à partir de l'échantillon généraliste des bénéficiaires (EGB).

OBJECTIVE: To estimate the costs of healthcare resource consumption in the year preceding and the year following a myocardial infarction (MI). PATIENTS AND METHODS: A historical cohort of patients experiencing an MI in France between 2007 and 2011 was extracted from the échantillon généraliste de bénéficiaires, a 1/97th sample of all beneficiaries of public health insurance in France. RESULTS: A total of 1920 patients experiencing an MI were identified. Two-thirds were men and the mean age was 67 years; 20.6% had diabetes, 37.6% hypercholesterolaemia and 82.4% hypertension. From a societal perspective, the annual costs of medical consumption related to hospitalisations increased from € 4548 before the MI to € 6470 in the following year. Costs of community care rose from € 2932 to € 6208. This increase concerned all components of community healthcare: costs associated with medical transportation increased fourfold, those associated with consultations and laboratory tests tripled, medication costs doubled and costs of paramedical services also increased, but to a lesser extent. It should be noted that the cost of hospitalisation for the index MI (€ 5876) is not included in the above costs. CONCLUSION: From a society perspective, the cost of healthcare resource consumption increased threefold in the year following an MI.

Clinical presentation of hyperthyroidism in a large representative sample of outpatients in France: relationships with age, aetiology and hormonal parameters.

OBJECTIVE: Signs and symptoms of thyrotoxicosis are not specific, and thyroid function tests are frequently prescribed to recognize such thyroid dysfunction. Ultrasensitive assays of thyroid-stimulating hormone (TSH) allow early diagnosis and identification of mild hyperthyroidism (generally designed as 'subclinical'). The aim of this study was to re-evaluate the clinical picture of thyrotoxicosis in the context of the current large utilization of ultrasensitive TSH assays. DESIGN: Prospective descriptive cohort. METHODS: Clinical presentation of 1572 patients with a recent (<3 months) diagnosis of thyrotoxicosis recruited by a large representative sample of 263 French endocrinologists was studied using two questionnaires (one at inclusion and the second after 3 months) concerning symptoms, hormonal evaluation and treatment. RESULTS: A total of 1240 (78·9%) patients were women, mean age 48 ± 17 years. Subclinical hyperthyroidism (SCHT) was present in 86 patients (10·4%). Symptoms of thyrotoxicosis were in decreasing frequency order: palpitations, weakness, heat-related signs and disturbed sleep. A total of 64·9% of patients had lost weight. Signs and symptoms were more frequent in Graves' disease, in young patients, and were partially related to biochemical severity. Symptoms were less frequent in elderly patients except for cardiac manifestations (atrial fibrillation). Most patients with SCHT had one or several signs or symptoms of thyrotoxicosis. CONCLUSION: This study confirms that elderly patients have less symptoms of thyrotoxicosis than younger subjects but are at increased risk of cardiac complications. Our results show that most patients with 'subclinical' HT have in fact signs or symptoms of thyrotoxicosis.

Identification of patients with gout: elaboration of a questionnaire for epidemiological studies.

OBJECTIVES: In France, the prevalence of gout is currently unknown. We aimed to design a questionnaire to detect gout that would be suitable for use in a telephone survey by non-physicians and assessed its performance. METHODS: We designed a 62-item questionnaire covering comorbidities, clinical features and treatment of gout. In a case-control study, we enrolled patients with a history of arthritis who had undergone arthrocentesis for synovial fluid analysis and crystal detection. Cases were patients with crystal-proven gout and controls were patients who had arthritis and effusion with no monosodium urate crystals in synovial fluid. The questionnaire was administered by phone to cases and controls by non-physicians who were unaware of the patient diagnosis. Logistic regression analysis and classification and regression trees were used to select items discriminating cases and controls. RESULTS: We interviewed 246 patients (102 cases and 142 controls). Two logistic regression models (sensitivity 88.0% and 87.5%; specificity 93.0% and 89.8%, respectively) and one classification and regression tree model (sensitivity 81.4%, specificity 93.7%) revealed 11 informative items that allowed for classifying 90.0%, 88.8% and 88.5% of patients, respectively. CONCLUSIONS: We developed a questionnaire to detect gout containing 11 items that is fast and suitable for use in a telephone survey by non-physicians. The questionnaire demonstrated good properties for discriminating patients with and without gout. It will be administered in a large sample of the general population to estimate the prevalence of gout in France.

Long-term outcomes and risk factors for failure with the EX-press glaucoma drainage device.

PURPOSE: To report on the long-term outcomes and risk factors for failure with the EX-PRESS shunt implanted under a scleral flap. SETTINGS: Eye Department, University of Ancona, Ancona, Italy and the Oxford Eye Center, University of Witwatersrand, Johannesburg, South Africa. METHODS: The medical records of glaucoma patients who underwent consecutive EX-PRESS implantations under a scleral flap between 2000 and 2009 were reviewed. The operations were performed by two experienced surgeons using an identical surgical technique. The potential risk factors for failure that were analysed included age, sex, race, glaucoma type, previous antiglaucoma medications, previous glaucoma surgeries, diabetes, and smoking. Complete success was defined as postoperative intraocular pressure (IOP) 5 mm Hg>IOP<18 mm Hg without antiglaucoma medications. Qualified success was defined as 5 mm Hg>IOP<18 mm Hg with or without antiglaucoma medications. RESULTS: Two hundred and forty-eight eyes of 211 consecutive patients were included. The mean IOP was reduced from 27.63 ± 8.26 mm Hg preoperatively (n=248) to 13.95 ± 2.70 mm Hg at 5 years (n=95). The mean follow-up was 3.46 ± 1.76 years. Complete and qualified success rates decreased gradually from 83% and 85% at 1 year to 57% and 63% at 5 years follow-up, respectively. The risk factors for failure were diabetes, non-Caucasian race, and previous glaucoma surgery. Complete success rates of diabetic patients and non-Caucasian patients decreased from 63% and 75% at 1 year to 42% and 40% at 5 years follow-up, respectively. CONCLUSIONS: EX-PRESS success rates decrease over time but compare favourably with trabeculectomy literature data. The main identifiable risk factors for failure are diabetes, non-Caucasian race, and previous glaucoma surgery.

Feasibility and acceptability of rapid HIV test screening (DEPIVIH) by French family physicians.

BACKGROUND: In France, around 50,000 people were unaware of their HIV positivity at the end of 2008. The latest guidelines recommend routine screening of all adults. Family physicians have been identified as key persons for this new policy. Rapid HIV tests (RHT) have been proposed as an alternative to conventional blood tests. OBJECTIVES: The authors assessed the feasibility and acceptability of RHT test based screening in French community practice. METHOD: We made a prospective interventional study of the BioMerieux VIKIA(®) HIV 1/2 RHT among French family physicians. Data on the RHT was posted in the physician's waiting room. RESULTS: Sixty-two French physicians, mostly family practitioners, included 383 patients with a mean age of 36.2 years, from June to October 2010. Twenty-two percent (83) of these patients had never been tested for HIV. The RHT was proposed and 382 tests were accepted and performed (acceptability rate of 99.7%). Sixty-five percent of the tests were made on the patient's request. The tested population represented 1.5% of consulting patients during the study period (feasibility rate). Patients were quite satisfied but physicians less so. Test steps and capillary blood sampling were the main source of difficulty mentioned. At the end of the study, 59% of physicians were ready to continue using RHT in their daily practice. CONCLUSION: Routine RHT screening in community practice is feasible and well accepted by patients. It was the first screening test for 22% of our patients. Its feasibility was limited by capillary blood sampling technique and time constraints during consultation.

Type 2 diabetes treatment intensification in general practice in France in 2008-2009: the DIAttitude Study.

AIMS: To evaluate the current procedures in French general practice of intensifying hypoglycaemic treatment in orally treated type 2 diabetic patients, according to the French recommendations. METHODS: Type 2 diabetic patient characteristics, HbA(1c) values, hypoglycaemic treatment and physician characteristics were collected from the electronic records of a panel of French general practitioners. Factors associated with the time until intensification of treatment were studied with the Cox model. RESULTS: Among 17 493 orally treated patients with at least two available HbA(1c) values, 3118 patients (18%) required treatment intensification; 65% were on monotherapy, 31% on bitherapy and 4% on tritherapy. These patients were followed for a maximum of 14 months or until treatment was intensified. Treatment was intensified after the second high HbA(1c) value for 1212 patients (39%); this was immediate for 13% of these patients, within 6 months for 39% and within one year for 59%. Treatment intensification was less likely the older the patient, and more likely the higher the first HbA(1c) value, up to an HbA(1c) threshold of 9%. CONCLUSIONS: Therapeutic inertia in caring for type 2 diabetic patients in France is frequent, at least for patients treated in general practice. This inadequate glycaemic control would be expected to have significant patient and public health consequences, with higher rates of associated diabetic complications.

A real-life study of the use, effectiveness and tolerability of rosiglitazone in France: the AVANCE study.

AIM: The study aimed to determine the effectiveness and tolerability of rosiglitazone, and its profile in terms of treatment adherence, treated patients and prescribing recommendations under everyday conditions of care. METHODS: This was a "real-life" observational longitudinal study including patients with type 2 diabetes mellitus (T2DM) starting treatment with rosiglitazone and followed for up to 2 years. A questionnaire was completed at the time of inclusion and during routine consultations at around 6, 12, 18 and 24 months following inclusion. Information was collected on sociodemographics, clinical history, treatments, co-morbidities, laboratory data and compliance with treatment. There were three primary outcome measures: treatment response (defined as an HbA1c ≤ 8.0% or a decrease in HbA1c ≥ 0.7%); switch to insulin (as considered necessary by the physician); and occurrence of adverse events requiring a change or discontinuation of treatment. RESULTS: The evaluation included 670 patients (61.1%) treated with rosiglitazone/metformin as fixed-dose combination tablets and 427 (38.9%) with standard rosiglitazone tablets. Rates of HbA1c response, defined as an HbA1c less than or equal to 8.0% or a decrease in HbA1c greater than or equal to 0.7%, ranged from 80.6% to 92.1% depending on the follow-up time. The percentage of patients with an HbA1c less than 7% was 18.4% before rosiglitazone was prescribed, and ranged from 48.2% to 57.8% depending on the follow-up period. Sixty-two patients (6.1%, 95% CI: 4.6-7.6%) switched to insulin therapy during the follow-up period. Spontaneously reported adverse events leading to a change or discontinuation of treatment were seen in 45 patients (4.4%, 95% CI: 3.2-5.6%). CONCLUSION: Rosiglitazone showed sustained efficacy, with around 90% of patients defined as responders to the treatment in terms of reduction in HbA1c, and was relatively well tolerated. The adverse-event profile was consistent with the known effects of rosiglitazone, and no signs of increased cardiovascular ischaemic risk were observed. These results are in agreement with previous studies on rosiglitazone.

[Projection of the incidence of breast cancer in France in 2018]. / Projection de l'incidence du cancer du sein en 2018 en France.

The objective of this work is to estimate the trends of the incidence of breast cancer until 2018, in the French context on the basis of an age cohort model. The model extrapolates the trend of incidence rate per generation and age, incorporates the effects of demographic changes in the female population in terms of size and age structure and simulates the impact of the withdrawal of the use of hormone therapy for menopause (HTM) under different assumptions. The results suggest a continuous growth in the number of incident cases that would increase from 49,814 to 64,621 between 2005 and 2018. Changes in incidence following the HTM use withdrawal, should be moderate and transient. The most important epidemiological parameters in explaining the future incidence of breast cancer remains the "cohort" effect that continues to have a significant impact until the extinction of cohorts for which the increase was more marked (birth years 1920 to 1945). This factor alone explains 18% of the growth in the number of incident cases in 2018, while the effect of population growth account for 6.6%, the cessation of HTM a 6.4% decrease and aging a 4.6% growth.

[Anogenital warts incidence, medical management and costs in women consulting gynaecologists in France]. / Incidence, prise en charge et coût des condylomes acuminés anogénitaux chez les femmes consultant leur gynécologue en France.

OBJECTIVES: The objectives of this study were to estimate the incidence of genital warts and treatment costs in women consulting gynaecologists in France in 2005. PATIENTS AND METHODS: A prospective observational study was performed through a representative sample of gynaecologists. Investigators enrolled all patients seen with genital warts during a 2-month period. A questionnaire detailing socio-demographic characteristics, case description, patient's clinical profile, past/ current management, and treatment of genital warts was completed by the investigators. RESULTS: 212 gynaecologists participated in the study. Questionnaires were completed for 263 patients including 198 (75.3%) new cases, 53 (20.2%) recurrent cases and 12 (4.5%) resistant cases. The overall incidence was estimated at 228.9/100,000 (female 15-65year old population) corresponding to 47,755 cases annually managed by gynaecologists in France. The average treatment cost was 482.70euro for society and 342.40 euro for third-party payers. The annual direct cost of genital warts management was estimated at 23,051,339euro, of which 16,351,312euro was funded by the French health care system. DISCUSSION AND CONCLUSION: The costs of treating genital warts are considerable. The introduction of a quadrivalent (type 6,11,16,18) Human Papillomavirus vaccine including types responsible for 90% of genital warts could potentially substantially reduce these costs.
