RESUMO

BACKGROUND & AIMS: Limited data are available on the consequences of prenatal exposure to vedolizumab and ustekinumab. We aimed to compare the safety of vedolizumab and ustekinumab with that of anti-tumor necrosis factor (TNF) in pregnant women with inflammatory bowel diseases (IBD). METHODS: Using nationwide, comprehensive data of the EPI-MERES registry, we identified pregnancies in women with IBD in France, exposed to anti-TNF, vedolizumab, and ustekinumab between 2014 and 2021. We compared pregnancy outcomes and complications in the offspring according to treatment exposure during pregnancy. We applied a propensity score matching for maternal, IBD, and pregnancy characteristics. RESULTS: Three hundred ninety-eight pregnancies exposed to vedolizumab were compared with 1592 pregnancies exposed to anti-TNF; 464 pregnancies exposed to ustekinumab were compared with 1856 pregnancies exposed to anti-TNF. Overall, compared with anti-TNF, neither vedolizumab nor ustekinumab was associated with increased risks of abortion, caesarean section, stillbirth, preterm birth, serious infections, malignancies, or congenital abnormality in children. Women exposed to ustekinumab had an increased risk of small for gestational age births. CONCLUSIONS: Overall, the safety of vedolizumab and ustekinumab compared with anti-TNF use during pregnancy is reassuring. Further studies are needed to confirm these findings.

RESUMO

BACKGROUND: Multiple sclerosis (MS) frequently affects women of childbearing age and pregnant women. OBJECTIVE: To assess the use of MS disease-modifying therapies (DMTs) during pregnancy in France over the last decade, marked by an increasing DMTs availability. METHODS: All pregnancies ended from April 2010 to December 2021 in women with MS were identified based on the nationwide Mother-Child Register EPI-MERES, built from the French National Health Data System (Système National des Données de Santé (SNDS)). RESULTS: Of a total of 20,567 pregnancies in women with MS, 7587 were exposed to DMT. The number of DMT-exposed pregnancies markedly increased from 1079 in 2010-2012 to 2413 in 2019-2021 (+124%), especially those exposed to glatiramer acetate, natalizumab, dimethyl fumarate, and anti-CD20. Among pregnancies of women on DMT 6 months before pregnancy, 78.0% underwent DMT discontinuation and 7.6% switched DMT, generally before (33.0% and 77.0%, respectively) or during the first trimester of pregnancy (58.3% and 17.8%, respectively). DMT discontinuation decreased from 84.0% in 2010-2012 to 72.4% in 2019-2021 and was less frequent among women aged ⩾35 years and those socioeconomically disadvantaged. CONCLUSION: Despite MS therapeutic management adaptations to pregnancy, exposure during pregnancy to treatments whose safety profile has not yet been clearly established has increased sharply over the last decade.

RESUMO

BACKGROUND: Although bacterial infections are frequent during pregnancy, the prescription of antibiotics to pregnant women represents a challenge for physicians, driven by the benefit-risk balance. OBJECTIVES: To assess the extent of prenatal antibiotic exposure and its associated factors. METHODS: This study included pregnancies in the National Mother-Child EPI-MERES Register 2010-19 (built from the French Healthcare Data System) regardless of outcome. Antibiotic exposure was defined as having at least one antibiotic prescription filled during pregnancy. The prevalence of pregnancies exposed to antibiotics was estimated. Univariable Poisson regression with generalized estimating equations was used to compare the number of antibiotic prescriptions filled during pregnancy and the period after pregnancy with the period 1 year before pregnancy. Multivariable Poisson regression was used to investigate factors associated with antibiotic exposure during pregnancy. RESULTS: Among 9 769 764 pregnancies, 3 501 294 (35.8%) were exposed to antibiotics and amoxicillin was the most common. Compared with a similar period 1 year before pregnancy, the number of filled antibiotic prescriptions was lower during pregnancy [incidence rate ratio (IRR) 0.903 (95% CI 0.902-0.905)] and during the period 1 year after pregnancy [IRR 0.880 (95% CI 0.879-0.881)]. Region of residence, deprivation index, smoking-related conditions and chronic diseases (especially chronic respiratory diseases) were associated with antibiotic exposure during pregnancy. CONCLUSIONS: Antibiotic prescriptions are filled less frequently during pregnancy than during the preceding year. This may be due to a more relevant benefit-risk assessment. Pregnant women living with social deprivation, those with smoking-related conditions and those with chronic diseases are more likely to fill antibiotic prescriptions.

RESUMO

BACKGROUND: Many biologics are available for psoriasis and have been compared in real-life studies based on their persistence (i.e. time between initiation and discontinuation). However, after first-line biologic failure, data are lacking on the choice of second-line biologic among the four available classes [tumour necrosis factor inhibitors (TNFi); interleukin (IL)-12/IL-23 inhibitor (IL-12/IL-23i); IL-17 inhibitors (IL-17i); and IL-23 inhibitors (IL-23i)]. OBJECTIVES: To compare the long-term persistence of available second-line biologics in psoriasis according to prior exposure. METHODS: This nationwide cohort study involved the administrative healthcare database of the French health insurance scheme linked to a hospital discharge database. Participants were adults with psoriasis, defined as having at least two prescriptions of a topical vitamin D derivative within a 2-year period, with initiation of a second-line biologic between 1 January 2015 and 31 December 2021. We included patients who initiated a second-line biologic directly after first-line discontinuation (i.e. without a 'washout' period). The end of follow-up was 30 June 2022. Discontinuation was defined as > 90 days without filling a prescription for the same treatment after the period covered by the previous prescription. Comparison of persistence by biologic class involved using propensity score-weighted Cox models (inverse probability treatment weighting) and adjustment of specific systemic nonbiologics (time-dependent variables). RESULTS: We included 8693 patients [mean (SD) age 50 (14) years; 50.5% male]; 2824 (32.5%) started TNFi, 1561 (18.0%) IL-12/IL-23i, 2707 (31.1%) IL-17i and 1601 (18.4%) IL-23i. Overall, 1- and 3-year persistence rates were 60% and 30%, respectively. After weighting and adjustment, persistence was longer with IL-12/IL-23i [weighted hazard ratio (HRw) 0.68, 95% confidence interval (CI) 0.62-0.76)], IL-17i (HRw 0.70, 95% CI 0.64-0.78) and IL-23i (HRw 0.36, 95% CI 0.31-0.42) than TNFi, except after first-line IL-17i treatment, with no difference between IL-12/IL-23i, IL-17i and TNFi second-line persistence. Persistence was longer with IL-23i as a second-line treatment than IL-12/IL-23i (HRw 0.53, 95% CI 0.44-0.63) and IL-17i (HRw 0.51, 95% CI 0.44-0.60), regardless of first-line treatment, with no difference seen between IL-12/IL-23i and IL-17i (HRw 0.97, 95% CI 0.87-1.09). CONCLUSIONS: This real-life study suggests the longer persistence of IL-23i than TNFi, IL-17i and IL-12/IL-23i as second-line treatment for psoriasis. Persistence rates for all biologics remained low at 3 years.

RESUMO

AIMS: To describe the trends in anti-infective use during pregnancy between 2010 and 2019 and determine whether they were prescribed according to drug foetal safety international classification systems. METHODS: We conducted a population-based, nationwide study using the French national health data system including all pregnancies ended between 2010 and 2019. Anti-infective agents were considered according to their pharmacological group and potential harmful risk using the Australian and Swedish classification systems. Prevalence rate was estimated annually and by trimester. Average annual percent change (AAPC) and 95% confidence intervals (CIs) were calculated using Joinpoint regression. RESULTS: Among 7 571 035 pregnancies, 3 027 031 (40.0%) received ≥1 antibacterial. This proportion decreased significantly from 41.5% in 2010 to 36.1% in 2019 (AAPC = -1.7%, [95%CI, -2.5 to -1.0%]). Conversely, use of antiviral agents increased during the 10-year study period for anti-herpes simplex virus agents (AAPC = 4.4%, [3.7-5.2%]), influenza agents (AAPC = 25.4%, [6.2-48.1%]) and for HIV-antiretroviral agents (AAPC = 1.3%, [0.6-2.0%]). Use of influenza vaccine increased from 0.2% in 2010 to 4.2% in 2019 (AAPC = 49.7%, [39.3-60.9%]). Among all pregnancies, 0.9% had been exposed to a potentially harmful anti-infective agent increasing from 0.7% in 2010 to 1.2% in 2019 (AAPC = 6.4%, [4.4-8.5%]). CONCLUSION: Based on >7 million pregnancies identified from French nationwide data, this study showed that antibacterials are frequently prescribed during pregnancy although their use has decreased over the past 10 years. Our results suggest that anti-infective agents are generally prescribed in accordance with recommendations, although with a potential for improvement in influenza vaccination.

RESUMO

INTRODUCTION: Depression is one of the most common co-morbidities during pregnancy; with severe symptoms, antidepressants are sometimes recommended. Social determinants are often linked with antidepressant use in the general population, and it is not known if this is the case for pregnant populations. Our objective was to determine if social determinants are associated with prenatal antidepressant intake via a systematic review and meta-analysis. METHODS: A systematic search of five databases was conducted to identify publications from inception to October 2022 that reported associations with prenatal antidepressant intake (use/continuation) and one or more social determinants: education, race, immigration status, relationship, income, or employment. Eligible studies were included in random effects meta-analyses. RESULTS: A total of 23 articles describing 22 studies were included. Education was significantly and positively associated with prenatal antidepressant continuation and heterogeneity was moderate. (Odds ratio = 0.83; 95% CI, 0.78 to 0.89; p < 0.00001; I2 = 53%). Meta-analyses of antidepressant use and education, race, and relationship status, and antidepressant continuation and income were not significant with high levels of heterogeneity. DISCUSSION: While most social determinants in this review were not linked with prenatal antidepressant intake, lower maternal education level does seem to be associated with lower rates of prenatal antidepressant continuation. CONCLUSIONS: Education appears to be linked with prenatal antidepressant intake. The low number of included studies precludes conclusive evidence for other social determinants.

RESUMO

BACKGROUND: Continuation of biologics for inflammatory disorders during pregnancy is still a difficult decision. Many women with inflammatory bowel diseases (IBDs) stop anti-tumor necrosis factor (anti-TNF) treatment after 24 weeks. OBJECTIVE: To evaluate the benefits and risks of anti-TNF continuation after 24 weeks of pregnancy for mothers with IBD and their offspring. DESIGN: Target trial emulation between 2010 and 2020. SETTING: Nationwide population-based study using the Système National des Données de Santé. PATIENTS: All pregnancies with birth exposed to anti-TNF between conception and 24 weeks of pregnancy in women with IBD. INTERVENTION: Continuation of anti-TNF after 24 weeks of pregnancy. MEASUREMENTS: Occurrence of maternal IBD relapse up to 6 months after pregnancy, adverse pregnancy outcomes, and serious infections in the offspring during the first 5 years of life was compared according to anti-TNF continuation after 24 weeks of pregnancy using inverse probability-weighted marginal models. RESULTS: A total of 5293 pregnancies were included; among them, anti-TNF treatment was discontinued before 24 weeks for 2890 and continued beyond 24 weeks for 2403. Continuation of anti-TNF was associated with decreased frequencies of maternal IBD relapse (35.8% vs. 39.0%; adjusted risk ratio [aRR], 0.93 [95% CI, 0.86 to 0.99]) and prematurity (7.6% vs. 8.9%; aRR, 0.82 [CI, 0.68 to 0.99]). No difference according to anti-TNF continuation was found regarding stillbirths (0.4% vs. 0.2%; aRR, 2.16 [CI, 0.64 to 7.81]), small weight for gestational age births (13.1% vs. 12.9%; aRR, 1.01 [CI, 0.88 to 1.17]), and serious infections in the offspring (54.2 vs. 50.2 per 1000 person-years; adjusted hazard ratio, 1.08 [CI, 0.94 to 1.25]). LIMITATION: Algorithms rather than clinical data were used to identify patients with IBD, pregnancies, and serious infections. CONCLUSION: Continuation of anti-TNF after 24 weeks of pregnancy appears beneficial regarding IBD activity and prematurity, while not affecting neonatal outcomes and serious infections in the offspring. PRIMARY FUNDING SOURCE: None.

RESUMO

BACKGROUND: The BNT162b2 (Pfizer-BioNTech) vaccine has been shown to be safe with regard to risk for severe cardiovascular events (such as myocardial infarction [MI], pulmonary embolism [PE], and stroke) in persons aged 75 years or older. Less is known about the safety of other COVID-19 vaccines or outcomes in younger populations. OBJECTIVE: To assess short-term risk for severe cardiovascular events (excluding myocarditis and pericarditis) after COVID-19 vaccination in France's 46.5 million adults younger than 75 years. DESIGN: Self-controlled case series method adapted to event-dependent exposure and high event-related mortality. SETTING: France, 27 December 2020 to 20 July 2021. PATIENTS: All adults younger than 75 years hospitalized for PE, acute MI, hemorrhagic stroke, or ischemic stroke (n = 73 325 total events). MEASUREMENTS: Linkage between the French National Health Data System and COVID-19 vaccine databases enabled identification of hospitalizations for cardiovascular events (MI, PE, or stroke) and receipt of a first or second dose of the Pfizer-BioNTech, mRNA-1273 (Moderna), Ad26.COV2.S (Janssen), or ChAdOx1 nCoV-19 (Oxford-AstraZeneca) vaccine. The relative incidence (RI) of each cardiovascular event was estimated in the 3 weeks after vaccination compared with other periods, with adjustment for temporality (7-day periods). RESULTS: No association was found between the Pfizer-BioNTech or Moderna vaccine and severe cardiovascular events. The first dose of the Oxford-AstraZeneca vaccine was associated with acute MI and PE in the second week after vaccination (RI, 1.29 [95% CI, 1.11 to 1.51] and 1.41 [CI, 1.13 to 1.75], respectively). An association with MI in the second week after a single dose of the Janssen vaccine could not be ruled out (RI, 1.75 [CI, 1.16 to 2.62]). LIMITATIONS: It was not possible to ascertain the relative timing of injection and cardiovascular events on the day of vaccination. Outpatient deaths related to cardiovascular events were not included. CONCLUSION: In persons aged 18 to 74 years, adenoviral-based vaccines may be associated with increased incidence of MI and PE. No association between mRNA-based vaccines and the cardiovascular events studied was observed. PRIMARY FUNDING SOURCE: None.

RESUMO

BACKGROUND & AIMS: We aimed to compare the risk of serious infections in children with in utero exposure to thiopurines and/or anti-tumor necrosis factor (TNF) born to mothers with inflammatory bowel disease (IBD). METHODS: Using the French national health database, which covers 99% of the French population (around 66,000,000 people), we identified live births among women with IBD in France between 2010 and 2018. The risks of serious infections in children during the first 5 years of life were compared according to treatment exposures during pregnancy using propensity score-weighted marginal Cox models. RESULTS: A total of 26,561 children were included: 3392 were exposed to thiopurine monotherapy, 3399 to anti-TNF monotherapy, 816 to combination therapy, and 18,954 were not exposed to any of these drugs. The risks of serious infections during the first year of life among children exposed to thiopurine monotherapy (adjusted hazard ratio [aHR], 0.94; 95% confidence interval [CI], 0.83-1.07) and anti-TNF monotherapy (aHR, 1.10; 95% CI, 0.95-1.27) were similar to those of unexposed children; a higher risk was observed in children exposed to combination therapy (aHR, 1.36; 95% CI, 1.04-1.79). The highest increased risks were observed for nervous system infections and viral infections. The risk of serious infections during the second to fifth years of life was not associated with IBD treatments. CONCLUSIONS: In children born to mothers with IBD, in utero exposure to thiopurine and anti-TNF monotherapies do not increase the risk of serious infections during the first 5 years of life. Combination therapy is associated with an increased risk of serious infections during the first year of life.

RESUMO

We propose a modified self-controlled case series (SCCS) method to handle both event-dependent exposures and high event-related mortality. This development is motivated by an epidemiological study undertaken in France to quantify potential risks of cardiovascular events associated with COVID-19 vaccines. Event-dependence of vaccinations, and high event-related mortality, are likely to arise in other SCCS studies of COVID-19 vaccine safety. Using this case study and simulations to broaden its scope, we explore these features and the biases they may generate, implement the modified SCCS model, illustrate some of the properties of this model, and develop a new test for presence of a dose effect. The model we propose has wider application, notably when the event of interest is death.

RESUMO

Our study aimed to analyze the risk of hematologic malignancies (HM) associated with the use of G-CSF with chemotherapy for BC. Using the French National Health Data System, we examined the HM risks in patients diagnosed with an incident breast cancer between 2007 and 2015, who received chemotherapy for BC. Main outcomes were acute myeloid leukemia (AML), Myelodysplastic syndrome (MDS), myeloproliferative neoplasms (MPNs), multiple myeloma (MM), Hodgkin lymphoma or non-Hodgkin lymphoma (HL/NHL) and acute lymphoblastic leukemia or lymphocytic lymphoma (ALL/LL). Among a total of 122 373 BC survivors, 38.9% received chemotherapy only and 61.1% received chemotherapy + G-CSF. Overall, 781 cases of hematologic malignancies occurred. We observed a nonsignificant increase in the risk of AML (aHR, 1.3; 95% CI, 1.0-1.7), of MDS (aHR, 1.3; 95% CI, 0.9-1.8) and of ALL/LL (aHR, 2.0; 95% CI, 1.0-4.4) among patients treated by chemotherapy + G-CSF compared to chemotherapy only. In analyses by dose, we observed a slight increase in the risk of AML (1-3 doses: aHR, 1.2; 95% CI, 0.8-1.7/4+ doses: aHR, 1.3; 95% CI, 1.0-1.8) and of MDS (1-3 doses: aHR, 1.1; 95% CI, 0.7-1.7/4+ doses: aHR, 1.4; 95% CI, 1.0-1.9), a significant increase in risk of ALL (1-3 doses: aHR, 1.5; 95% CI, 0.5-3.9 / 4+ doses: aHR, 2.3; 95% CI, 1.0-5.1) with increasing cycles of G-CSF. Our population-based study showed that the ALL/LL was the only HM at increased risk with the use of growth factors with a possible dose-effect relationship. Our data regarding the risk of all the other HM are reassuring.

RESUMO

Vitamin K antagonists (VKAs) have been used in 1% of the world's population for prophylaxis or treatment of thromboembolic events for 64 years. Impairment of osteoblast function and osteoporosis has been described in patients receiving VKAs. Given the involvement of cells of the bone marrow microenvironment (BMM), such as mesenchymal stem cells (MSCs) and macrophages, as well as other factors such as the extracellular matrix for the maintenance of normal hematopoietic stem cells (HSCs), we investigated a possible effect of VKAs on hematopoiesis via the BMM. Using various transplantation and in vitro assays, we show here that VKAs alter parameters of bone physiology and reduce functional HSCs 8-fold. We implicate impairment of the functional, secreted, vitamin K-dependent, γ-carboxylated form of periostin by macrophages and, to a lesser extent, MSCs of the BMM and integrin ß3-AKT signaling in HSCs as at least partly causative of this effect, with VKAs not being directly toxic to HSCs. In patients, VKA use associates with modestly reduced leukocyte and monocyte counts, albeit within the normal reference range. VKAs decrease human HSC engraftment in immunosuppressed mice. Following published examples that alteration of the BMM can lead to hematological malignancies in mice, we describe, without providing a causal link, that the odds of VKA use are higher in patients with vs without a diagnosis of myelodysplastic syndrome (MDS). These results demonstrate that VKA treatment impairs HSC function via impairment of the BMM and the periostin/integrin ß3 axis, possibly associating with increased MDS risk.

RESUMO

PURPOSE: We hypothesized that the COVID-19 pandemic may have modified dispensing of colonoscopy preparations, a proxy for the number of colonoscopies performed. We therefore studied changes in dispensing of colonoscopy preparations during the pandemic in France. METHODS: Using the French national health data system, we identified colonoscopy preparations dispensed from 2018 to 2020. The expected 2020 dispensations were estimated from 2018 to 2019 dispensations. RESULTS: Dispensing of colonoscopy preparations decreased markedly during the eight weeks of national lockdown: 83,045 colonoscopy preparations were dispensed, i.e., 181,826 (68.6%) fewer than expected. After lockdown, dispensing of colonoscopy preparations gradually returned to expected numbers. Overall, this represents an estimated decrease of roughly 250,000 colonoscopy preparations during the six-month period following onset of the pandemic. This shortfall in the dispensing of colonoscopy preparations was of the same order of magnitude in people under or over 50 years of age, in men and women, and in those in the highest and the lowest quintiles of the deprivation index. CONCLUSION: In conclusion, roughly 250,000 fewer colonoscopy preparations were dispensed during the first six months of the COVID-19 pandemic in France. Deleterious consequences on morbidity and mortality related to gastroenterological diseases, such as colorectal cancer, are to be feared.

RESUMO

PURPOSE: Proton pump inhibitor (PPI) drugs are approved for the management of gastric acid-related diseases, mainly treatment of gastroesophageal reflux disease, treatment of nonsteroidal anti-inflammatory drugs (NSAID)-related gastrointestinal complications and prevention in at-risk patients, Helicobacter pylori eradication, and treatment of ulcers. PPIs are one of the most commonly prescribed drug class worldwide, and off-label use is widespread. The aim of this study was to describe outpatient PPI use of the whole adult population in France, based on the French National Health Data System (SNDS). METHODS: All individuals aged 18 years or older, with at least one dispensing for PPI between January 1, 2015 and December 31, 2015, were identified as PPI users. PPI users were considered as new users if they received no dispensing for PPI in the prior year. New users were followed until treatment discontinuation or up to 1 year, whichever occurred first. Characteristics of new users and of their PPI treatment were described, overall and separately by treatment indication. RESULTS: In total, 15,388,419 PPI users were identified in 2015 (57.0% women; mean age 57.0 years), accounting for 29.8% of the French adult population. Of them, 7,399,303 were new PPI users; mean treatment duration was 40.9 days, and 4.1% received a continuous PPI therapy lasting more than 6 months (10.2% among new users > 65 years versus 2.4% among those 18-65 years). For 53.5% of new users, indication for PPI therapy was a co-prescription with NSAID; in this indication, the large majority of patients (79.7%) had no measurable risk factor supporting a systematic prophylactic co-prescription of PPI. A proportion of 32.4% of new users did not have any identified comedication or inpatient diagnosis supporting an indication for PPI therapy; among them, only a small proportion (7.3% overall, and 8.4% of patients aged > 65 years) underwent a procedure investigating the digestive tract at the time of PPI initiation. CONCLUSION: The results of this study suggest PPI overuse in France, not always in line with the French guidelines. In particular, inappropriate co-prescription with NSAID was frequent. Efforts should be made to limit PPI treatment to appropriate indications and durations.

RESUMO

BACKGROUND & AIMS: The risk of infection associated with tumor necrosis factor antagonists (anti-TNF) and thiopurines (combination therapy) is uncertain. We assessed the risk of serious and opportunistic infections in patients with inflammatory bowel disease (IBD) treated with thiopurine monotherapy, anti-TNF monotherapy, or combination therapy in a large cohort of patients in France. METHODS: We performed a nationwide population-based study of patients (18 years or older) with a diagnosis of IBD in the French national health insurance database; we collected data from January 1, 2009 until December 31, 2014. The risks of serious and opportunistic infections associated with exposure to combination therapy, anti-TNF, and thiopurine monotherapies were compared using marginal structural Cox proportional hazard models adjusted for baseline and time-varying sociodemographic characteristics, medications, and comorbidities. RESULTS: Among the 190,694 patients with IBD included in our analysis, 8561 serious infections and 674 opportunistic infections occurred. Compared with anti-TNF monotherapy, combination therapy was associated with increased risks of serious infection (hazard ratio [HR], 1.23; 95% confidence interval [CI], 1.05-1.45) and opportunistic infection (HR, 1.96; 95% CI, 1.32-2.91). Compared with thiopurine monotherapy, anti-TNF monotherapy was associated with increased risks of serious infection (HR, 1.71; 95% CI, 1.56-1.88), mycobacterial infection (HR, 1.98; 95% CI, 1.15-3.40), and bacterial infection (HR, 2.38; 95% CI, 1.23-4.58, respectively). Conversely, anti-TNF monotherapy was associated with decreased risk of opportunistic viral infection compared with thiopurine monotherapy (HR, 0.57; 95% CI, 0.38-0.87). CONCLUSIONS: In a nationwide cohort study of patients with IBD in France, we found heterogeneity in risks of serious and opportunistic infections in patients treated with immune-suppressive regimens. These should be carefully considered and weighed against potential benefits for IBD treatment in patient management.

RESUMO

Migrants from sub-Saharan Africa (SSA) are often diagnosed at an advanced stage of HIV, and many of them have harsh living conditions. We aimed to evaluate the entry into care after HIV diagnosis and examine the related social determinants. The ANRS PARCOURS study is a life-event survey conducted in 2012-2013 in the Paris region among. Time between HIV diagnosis of SSA migrants living diagnosed HIV positive in France and HIV care and the determinants was assessed yearly by using mixed-effects logistic regression models. Among a total of 792 participants, 94.2% engaged in HIV care within the year of HIV diagnosis, 4.3% in the following year and 2.5% beyond the second year after diagnosis. The participants were more likely to engage in HIV care during years when they were effectively covered by health insurance and if the HIV test was carried out at the initiative of the doctor. Immigration for economic reasons or owing to threats in his/her country of origin was associated with delayed engagement in HIV care. Additionally, 4.3% of treated participants discontinued HIV care at least once at the time of the survey and more often if diagnosed at an advanced HIV disease stage and financially dependent.

RESUMO

PURPOSE: To investigate the risk of acute kidney injury (AKI) in subjects initiating statin therapy for primary prevention of cardiovascular disease (CVD). METHODS: A nationwide cohort study using French hospital discharge and claims databases was performed, studying subjects from the general population aged 40 to 75 years in 2009, with no history of CVD and no lipid-lowering drugs during the preceding 3-year period, followed for up to 7 years. Exposure to statins (type, dose, and time since first use) and to other drugs for CVD risk was assessed. The primary outcome was hospital admission for AKI. RESULTS: The cohort included 8 236 279 subjects, 818 432 of whom initiated a statin for primary prevention. During 598 487 785 person-months exposed to statins, 700 events were observed, corresponding to an incidence of AKI of 4.59 per 10 000 person-years (7.01 in men, 3.01 in women). AKI mainly occurred in the context of organ failure, sepsis, and genitourinary disease. A 19% increased rate of AKI (hazard ratio = 1.19, 95%CI: 1.08-1.31) was observed in men exposed to statins, whereas no increase in the overall risk of AKI was observed in women. However, exposure to high-potency statins was associated with a 72% to 116% increased risk in both genders and a dose-effect relationship observed for rosuvastatin and atorvastatin. No temporal pattern of occurrence nor interaction with drugs for CVD risk was observed. CONCLUSIONS: Although the overall risk of AKI appears moderately increased, more attention should be paid to renal function in subjects taking statins for primary prevention both in clinical practice and from a research viewpoint.

RESUMO

BACKGROUND: Unlike their younger counterparts, some of today's older HIV patients were diagnosed before the advent of highly active antiretroviral therapy (HAART). The psychosocial and behavioral outcomes of people living with HIV (PLWH) have been widely studied, and associated factors are well known. However, their evolution both in terms of age and diagnosis-specific cohort effects is not well understood. METHODS: Data from the ANRS-VESPA2 cross-sectional survey, representative of French PLWH, were used to investigate whether psychosocial and behavioral outcomes such as quality of life, need for support and HIV status disclosure, evolve under both the influence of patients' age and diagnosis-specific cohort effects. A semi-parametric generalized additive model (GAM) was employed. The physical and mental components of health-related quality of life, the need for material and moral support, and HIV-status disclosure, constituted our outcomes. RESULTS: Non-linear diagnosis-specific cohort effects were found for physical and mental QoL and HIV-status disclosure. Overall, physical QoL was better in recently diagnosed patients than in those diagnosed in the early 1980s. An increasing influence of diagnosis-specific cohort effects between 1983 and 1995 was observed. No cohort effects were noticeable between 1996 and 2000, while an increasing influence was apparent for patients diagnosed with HIV from 2000 to 2011 (year of study). For mental QoL, the only increase was observed in participants diagnosed with HIV between 1983 and 2000. The relationship between diagnosis-specific cohort effects and HIV status disclosure was negative overall: participants diagnosed after 2000 were much less likely to disclose than those diagnosed before 1995. The effect of age was significantly associated with all outcomes, with a non-linear influence on mental QoL and with the need for material/moral support. CONCLUSIONS: Psychosocial and behavioral outcomes are complex processes which can be explained in different ways by a combination of the clinical and social contexts which PLWH are exposed to at the time of diagnosis, and by developmental characteristics. A greater understanding of these processes could inform healthcare policy-making for specific HIV generations and different HIV age groups.
