Tandem hemodialysis and DFPP: Procedure, safety and cost-effectiveness in patients requiring chronic hemodialysis and lipid apheresis.

INTRODUCTION: Certain patients require simultaneous lipoprotein apheresis (LA) and intermittent hemodialysis (HD). Instead of undergoing 2 consecutive treatment sessions, a double filtration plasmapheresis (DFPP) and HD tandem procedure could be offered to reduce treatment times and costs. Our study evaluated the performance, safety and cost of this tandem procedure. MATERIAL AND METHODS: Three patients underwent 168 HD and DFPP tandem sessions in a tertiary center from August 2018 to November 2020, using a Fresenius 5008 generator for HD and an InfomedHF440 for DFPP. The system's efficacy was assessed by lipid subtraction performance for DFPP. Efficacy of 2 blood line connection configurations (parallel or sequential) was compared in terms of Kt/V and matched against an HD control session for each patient. Clinical and biological safety and the differential cost between tandem and consecutive procedures were evaluated. RESULTS: Throughout the tandem sessions, DFPP lasted 85 to 120 minutes, overlapping the 240-minute HD. Blood flow for HD and Kt/V were significantly lower during the tandem procedure with a parallel configuration compared to sequential or control paired HD. DFPP efficacy was comparable between all groups: over 60% reduction in cholesterol and over 50% for triglycerides. Symptomatic hypotension depended on the patients, not the procedure. The tandem procedure revealed an acceptable benefit-cost ratio. CONCLUSION: HD-DFPP tandem with a sequential blood line connecting system (derivation installed on the HD venous line) is effective and well-tolerated with a good cost-benefit ratio. Tandem reduces hospitalization and treatment session times and can be offered to patients requiring simultaneous HD and DFPP.

Multi-trajectories of antidepressant and antipsychotic use: a 11-year naturalistic study in a community-based sample.

OBJECTIVE: To explore the temporal dynamic of antidepressant and antipsychotic co-prescribing in real-life conditions. METHODS: The study was performed using reimbursement data from the French Insurance Healthcare system in a cohort of 118 454 persons with at least one dispensing of antidepressants and/or antipsychotics over the period 2006-2016. Latent class analyses were used to identify homogeneous groups of persons following similar multi-trajectories of antidepressant and/or antipsychotic dispensing. Multivariate polynomial logistic regression models were used to explore the characteristics independently associated with distinct trajectories. RESULTS: Five multi-trajectories of antidepressant and/or antipsychotic dispensing were identified: more than half of the sample (58%) had very low antidepressant and antipsychotic use; two groups had chronic (12%) or decreasing (11%) antidepressant use with very low antipsychotic use; two groups used both antidepressants and antipsychotics simultaneously either in an increasing (12%) or chronic (7%) way. Persons with chronic antidepressant-antipsychotic use presented with markers of poor social and mental health conditions. CONCLUSIONS: Most persons using antipsychotics over the follow-up also used antidepressants over the same period. The benefit/risk ratio of these prescribing practices should be further explored as the long-term efficacy of antidepressant-antipsychotic polypharmacy is poorly documented, while this combination increases the risk of adverse effects.

Risk of discontinuation of antipsychotic long-acting injections vs. oral antipsychotics in real-life prescribing practice: a community-based study.

OBJECTIVE: To compare the risk of discontinuation of ambulatory antipsychotic treatment in persons treated with antipsychotic long-acting injections (LAIs) or by oral antipsychotics (OAPs). METHODS: The study was performed in a representative sample of persons newly treated with OAPs (n = 6904) affiliated to the French Insurance Healthcare system. The risk of all-cause discontinuation was compared in patients prescribed OAPs (n = 246) vs. matched patients prescribed LAIs (n = 246) using multivariate survival analyses. Confounding by indication was minimized by matching on type of antipsychotic drug and by the high-dimensional propensity score method. RESULTS: Discontinuation was more frequent with OAPs (69%) compared to LAIs (57%) [adjusted relative risk (aRR) = 1.6, 95% CI 1.23-2.07]. Risk of discontinuation was higher for first-generation (FGA) OAPs vs. FGA LAIs (aRR = 1.94, 95% CI 1.22-3.08) as well as for second-generation (SGA) OAPs vs. SGA LAIs (aRR = 1.58, 95% CI 1.15-2.17). Over the 6-month period after discontinuation of LAIs, a new antipsychotic drug was dispensed in 58% of patients, the most frequent pattern being dispensing of the same LAI as that prescribed before discontinuation. CONCLUSIONS: Although less frequent than with OAPs, the rate of ambulatory treatment discontinuation was high with LAIs. Prescription of LAIs should be associated with intervention strategies aimed at promoting medication adherence.

Geographical disparities in prescription practices of lithium and clozapine: a community-based study.

OBJECTIVE: To explore the socioeconomic and health resource characteristics associated with geographical variations of lithium and clozapine dispensing rates in France. METHOD: The study was performed using reimbursement data from the French Insurance Healthcare system over the period 2006-2013 in a community-based sample of persons aged 16 years and over. An ecological design was used to assess whether lithium and clozapine prescribing rates were associated with socioeconomic and health resource characteristics of the zone of residence (n = 95 French administrative subdivisions). RESULTS: Large geographical disparities were observed in dispensing rates: lithium dispensing rates by zone of residence ranged from 0 to 6.6 per 1000 (mean 2.4 per 1000) and clozapine dispensing rates ranged from 0 to 4.9 per 1000 (mean 0.8 per 1000). Higher density of GPs and regular communication between mental health services and primary care were independently associated with higher rates of lithium and clozapine dispensing and with a higher proportion of lithium users among mood-stabilizer users. CONCLUSION: A sufficient density of GPs and an effective communication and collaboration between mental healthcare services and primary care seems to favor greater access to psychotropic drugs with demonstrated efficacy but often viewed as 'risky' to prescribe.

Comparison of transient elastography (FibroScan), FibroTest, APRI and two algorithms combining these non-invasive tests for liver fibrosis staging in HIV/HCV coinfected patients: ANRS CO13 HEPAVIH and FIBROSTIC collaboration.

OBJECTIVES: Combining noninvasive tests increases diagnostic accuracy for staging liver fibrosis in hepatitis C virus (HCV)-infected patients, but this strategy remains to be validated in HIV/HCV coinfection. We compared the performances of transient elastography (TE), Fibrotest (FT), the aspartate aminotransferase-to-platelet ratio index (APRI) and two algorithms combining TE and FT (Castera) or APRI and FT (SAFE) in HIV/HCV coinfection. METHODS: One hundred and sixteen HIV/HCV-coinfected patients (64% male; median age 44 years) enrolled in two French multicentre studies (the HEPAVIH cohort and FIBROSTIC) for whom TE, FT and APRI data were available were included in the study. Diagnostic accuracies for significant fibrosis (METAVIR F ≥ 2) and cirrhosis (F4) were evaluated by measuring the area under the receiver-operating characteristic curve (AUROC) and calculating percentages of correctly classified (CC) patients, taking liver biopsy as a reference. RESULTS: For F ≥ 2, both TE and FT (AUROC = 0.87 and 0.85, respectively) had a better diagnostic performance than APRI (AUROC = 0.71; P < 0.005). Although the percentage of CC patients was significantly higher with Castera's algorithm than with SAFE (61.2% vs. 31.9%, respectively; P < 0.0001), this percentage was lower than that for TE (80.2%; P < 0.0001) or FT (73.3%; P < 0.0001) taken separately. For F4, TE (AUROC = 0.92) had a better performance than FT (AUROC = 0.78; P = 0.005) or APRI (AUROC = 0.73; P = 0.025). Although the percentage of CC patients was significantly higher with the SAFE algorithm than with Castera's (76.7% vs. 68.1%, respectively; P < 0.050), it was still lower than that for TE (85.3%; P < 0.033). CONCLUSIONS: In HIV/HCV-coinfected patients, TE and FT have a similar diagnostic accuracy for significant fibrosis, whereas for cirrhosis TE has the best accuracy. The use of the SAFE and Castera algorithms does not seem to improve diagnostic performance.

Clozapine use pattern in persons with and without treatment for Parkinson's disease in real-world conditions: a naturalistic study in a community-based sample.

OBJECTIVE: To explore the pattern of clozapine use in persons with severe mental illness and in persons with Parkinson's disease and the characteristics associated with early discontinuation in naturalistic conditions. METHOD: A historical fixed cohort study of persons newly treated with clozapine was performed on a representative community-based sample of persons affiliated to the French health insurance system (n = 611,393). Treatment for Parkinson's disease was used as a proxy for this condition and lack of such treatment as a proxy for severe mental illness (SMI). RESULTS: The prevalences of antipsychotic and clozapine use were 4.4% and <0.1% respectively. Of the 237 persons with a new outpatient prescription of clozapine, 25% were prescribed an antiparkinsonian treatment. In persons with SMI, the median duration of the index episode of clozapine treatment was 4.9 months (Interquartile range 1.0-20.5). Longer duration was independently associated with coprescription of anxiolytics or antidepressant. Few new additions of antipsychotics were observed during the clozapine episode. CONCLUSION: Efforts have to be made to optimize clozapine treatment in real-world conditions. Considering the high frequency of persons with Parkinson's disease among clozapine users, further studies have to be performed in this population.

Factors associated with guideline-based hepatitis C virus (HCV) treatment initiation in HIV/HCV-coinfected patients: role of comorbidities and physicians' perceptions.

OBJECTIVES: Many HIV-infected patients with chronic hepatitis C virus (HCV) infection do not receive treatment for HCV infection, often because of contraindications or poor adherence to anti-HIV therapy. The aim of this study was to identify factors influencing guideline-based HCV treatment initiation in a large cohort of HIV/HCV-coinfected patients. METHODS: Between 2005 and 2011, 194 (40.5%) of 479 coinfected patients not previously treated for HCV infection started this treatment based on current recommendations, i.e. a Metavir score >F1 for liver fibrosis; HCV genotype 2 or 3 infection; or HCV genotype 1 or 4 infection and low HCV viral load (<800000 IU/mL), whatever the fibrosis score. Clinical and biological data were compared between patients who started HCV therapy during follow-up and those who did not. RESULTS: In multivariate analyses, good adherence to treatment for HIV infection, as judged by the patient's physician, was associated with HCV treatment initiation [odds ratio (OR) 2.37; 95% confidence interval (CI) 1.17-4.81; P=0.017], whereas patients with children (OR 0.53; 95% CI 0.30-0.91; P=0.022) and those with cardiovascular disease or respiratory distress (OR 0.10; 95% CI 0.01-0.78; P=0.03) were less likely to be treated. CONCLUSIONS: Adherence to treatment for HIV infection, as judged by the patient's physician, appears to have a major influence on the decision to begin treatment for HCV infection in coinfected patients. This calls for specific therapeutic education and adherence support in order to ensure timely anti-HCV therapy in this population.

Maternal post-natal depressive symptoms at 2 months: Effects of French antenatal preventive measures in the E.L.F.E. cohort.

BACKGROUND: Given the high incidence of perinatal maternal depression, implementation of preventive actions is crucial. In France, two prenatal preventive measures are available to the general population: early prenatal interview (EPI) and antenatal classes (ANC). OBJECTIVE: To explore the independent associations between EPI and / or ANC and maternal depressive symptoms at 2 months postpartum. METHOD: We used data from the Etude Longitudinale Française depuis l'Enfance (ELFE), a French national representative cohort of children and their parents, followed-up from birth to early adulthood. Data concerning characteristics were collected from the mothers during the maternity stay and between 6/8 weeks' post-partum. The level of depressive symptoms was scored by the French version of the Edinburgh Postnatal Depression Scale (EPDS) between 6/8 weeks' post-partum. We considered EPDS score ≥10 indicative of postnatal psychological distress (PPD) and EPDS ≥12 for postnatal depressive symptoms (PNDS). After data imputation, multivariate logistic regression analysis was performed. RESULTS: Among the 16,411 mothers included in our sample, 26% benefited both from EPI and ANC, 31.1 % of ANC, 7.7% of an EPI and 35% of neither; 20,1% presented PPD and 12,1% PNDS. The likelihood of presenting PPD was significantly higher in mothers who had neither had EPI nor ANC (OR = 1.15 (95% CI : 1.01-1.30). There was no association between receiving or not an EPI and/or ANC and presenting PNDS. CONCLUSIONS: Antenatal preventive measures may be helpful to prevent PPD at 2 months' post- partum, while PNDS do not seem to be influenced by these actions.

[Early prenatal interview and antenatal education for childbirth and parenthood: Associated psychosocial and obstetric characteristics in women of the ELFE cohort]. / Entretien prénatal précoce et séances de préparation à la naissance et à la parentalité : caractéristiques psychosociales et obstétricales associées chez les femmes de la cohorte ELFE.

OBJECTIVES: Early prenatal interview (Entretien prénatal précoce [EPP]) is aimed at defining with couples their physical, psychological and social needs during perinatal period. Antenatal education for childbirth and parenthood (Préparation à la naissance et à la parentalité [PNP]) is aimed at promoting global perinatal health. The objective was to identify the psychological, demographic and obstetrical characteristics independently associated with participation in: (i) an EPP; (ii) a PNP. MATERIALS AND METHODS: Multivariate analyses were applied to data collected during the maternity stay of mothers whose children were included in the French cohort French Longitudinal Study since the Childhood (ELFE), a nationally representative cohort of children followed-up from birth to adulthood. RESULTS: Among the 14,595 mothers of the sample, 33% had an EPP and 52% a PNP. Primiparous mothers, born in France, with high educational level, employed or unemployed, with psychological difficulties more often benefit from EPP and/or PNP. Women who were young, benefiting from free health insurance (Couverture Maladie Universelle [CMU]), with unplanned pregnancy, with less antenatal care and obstetrical complications less often benefit from PNP. CONCLUSION: The EPP and the PNP reach high sociodemographic level populations. They should be integrated into a wider system of prevention and care, in order to reach the most vulnerable populations and to contribute to the improvement of the psychological and social environment of all the women during the perinatal period.

Prenatal psychological distress and access to mental health care in the ELFE cohort.

BACKGROUND: Pregnant women are vulnerable to the deleterious impact of environmental stressors. The aims were to identify the environmental and pregnancy characteristics independently associated with prenatal psychological distress and access to mental health care. METHODS: We used data from the French cohort Étude Longitudinale Française depuis l'Enfance (ELFE), a nationally representative cohort of children followed-up from birth to adulthood. Information about prenatal psychological status and access to mental health care was collected during the maternity stay. Maternal/pregnancy characteristics independently associated with psychological distress and access to mental health care were explored using multivariate analyses. RESULTS: Of the 15,143 mothers included, 12.6% reported prenatal psychological distress. Prenatal distress was more frequent in women with very low economical status, alcohol/tobacco use, unplanned/unwanted pregnancy, late pregnancy declaration, multiparity and complicated pregnancy (high number of prenatal visits, prenatal diagnosis examination, obstetrical complications). Of the women reporting prenatal distress, 25% had a prenatal consultation with a mental health specialist and 11% used psychotropic drugs during pregnancy. Decreased likelihood to consult a mental health specialist was found in young women, with intermediate educational level and born abroad. LIMITATIONS: Causal inferences should be made cautiously as the questionnaire did not collect information on the temporal sequence between psychological distress and associated characteristics. CONCLUSIONS: Women with social and obstetrical vulnerabilities are at increased risk of poor mental health during pregnancy. Improving mental health care access during pregnancy is a public health priority.

Prevalence of immunity to hepatitis viruses A and B in a large cohort of HIV/HCV-coinfected patients, and factors associated with HAV and HBV vaccination.

UNLABELLED: Hepatitis A (HAV) and B (HBV) vaccination is strongly recommended for HIV-infected patients, especially those with hepatitis C coinfection. The aim of this study was to determine the prevalence of antibodies directed against HAV and HBV in a large cohort of HIV/HCV-coinfected patients, and to identify factors associated with HAV and HBV vaccination. PATIENTS AND METHODS: We studied 1175 HIV/HCV-coinfected patients enrolled in the ANRS CO13 HEPAVIH cohort, whose HAV and HBV serostatus was known. RESULTS: 1056 patients (89.9%) have been tested for anti-HBc IgG, anti-HBs, and HbsAg. Only 10.9% of patients had received HBV vaccination and 70% of the patients with no HBV immunity (231/265) had never received HBV vaccination. In multivariate analysis, male sex (OR 2.0. 95% CI 1.1-3.8; p=0.02), a higher level of school education (OR 2.5, 95% CI 1.3-4.5; p=0.003), a higher CD4 cell nadir (OR 1.05, 95% CI 1.009-1.103; p=0.018) and no cirrhosis (OR 2.7, 95% CI 1.2-6.4; p=0.02) were associated with HBV vaccination. Only 368 patients (31.3%) were tested for immunity to HAV. Despite a frequent lack of HAV immunity (48.3%), a low rate of HAV vaccination (6%) was observed. In multivariate analysis, a higher level of school education (OR 3.6, 95% CI 1.03-12.4; p=0.045) was the only factor associated with HAV vaccination. HAV screening rates and HAV and HBV vaccination rates were low in this population of HIV/HCV-coinfected patients. The benefits of routine HAV and HBV screening, vaccination and post-vaccination testing should be emphasized.
