Home NIV treatment quality in patients with chronic respiratory failure having participated to the French nationwide telemonitoring experimental program (The TELVENT study). Respir Med Res 2023; 84:101028. [PMID: 37683442 DOI: 10.1016/j.resmer.2023.101028] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Revised: 03/24/2023] [Accepted: 05/15/2023] [Indexed: 09/10/2023]
Abstract
BACKGROUND The ETAPES program is a national telemedicine experiment conducted in France between 2018 and 2023 to investigate whether home non-invasive ventilation (NIV) telemonitoring improves healthcare pathways in patients with chronic respiratory failure (CRF) and impacts healthcare organization. The program provides a combination of therapeutic education and NIV telemonitoring with data processed by an algorithm generating alerts. The TELVENT study objective was to analyze the evolution of ventilation quality in patients included in the ETAPES program. METHODS Multicentric cohort study on patients undergoing long-term NIV included in the ETAPES program between September 2018 and December 2020 and who did not refuse the use of their data for this research. Data were obtained from homecare provider databases. The primary endpoint was to attain successful NIV treatment, which was determined by a combination of daily NIV usage for > 4 h per day, low leaks, and a low apnea-hypopnea index (AHI) identified by the NIV device. Respiratory disability was assessed using the DIRECT questionnaire. RESULTS 329 patients were included in the study of which 145 had COPD and 83 had started NIV and ETAPES within one-month delay. Approximately 25% of patients did not achieve the criteria for successful NIV at ETAPES entry. The proportion of patients with successful NIV treatment increased to 86.8% at six months (p = 0.003, Cochran-Armitage trend test) regardless of NIV history and continued to increase at 12 months in newly equipped NIV patients (93.8%, at month 12, p = 0.0026 for trend test). Over time, a significant increase in NIV use and compliance was observed, while AHI significantly decreased in the overall population. No significant decrease was observed for non-intentional leaks. Approximately 4.9 alerts were generated per patient per 6 months. Their number and type (low NIV use, high AHI or leaks) differed among patients based on their NIV history. Respiratory disability score decreased over time compared with baseline. CONCLUSION The TELVENT study highlights the importance of remote NIV monitoring to rapidly identify patients with unsuccessful ventilation. The combination of remote monitoring and therapeutic education may improve the quality of home NIV, especially in the first months of treatment.

Abstract
Background Long-term changes in lung cancer (LC) patients are difficult to evaluate. We report results from the French KBP-2020 real-life cohort. Methods KBP-2020 was a prospective cohort that included all patients diagnosed with LC in 2020, in nonacademic public hospital in France. Patient and tumour characteristics were described and compared with similarly designed cohorts in 2000 and 2010. Findings In 2020, 82 centers included 8,999 patients diagnosed with LC. The proportion of women increased: 34·6% (3114/8999) compared to, 24·3% (1711/7051) and 16·0% (904/5667) in 2010 and 2000 (p<0·0001). The proportion of non-smokers was higher in 2020 (12·6%, 1129/8983) than in previous cohorts (10·9% (762/7008) in 2010; 7·2% (402/5586) in 2000, p<0·0001). In 2020, at diagnosis, 57·6% (4405/7648) of patients had a metastatic/disseminated stage non-small-cell lung cancer (NSCLC) (58·3% (3522/6046) in 2010; 42·6% (1879/4411) in 2000, p<0·0001). Compared with 2000 and 2010 data, early survival improved slightly. In 2020, 3-month mortality of NSCLC varied from 3·0% [2·2 – 3·8] for localized to 9·6% [8·1 – 11·0] for locally advanced to 29·2% [27·8 – 30·6] for metastatic and was 24·8% [22·3 – 27·3] for SCLC. Interpretation To our knowledge KBP cohorts have been the largest, prospective, real-world cohort studies involving LC patients conducted in worldwide. The trend found in our study shows an increase in LC in women and still a large proportion of patients diagnosed at metastatic or disseminated stage. Funding The study was promoted by the French College of General Hospital Pulmonologists with financial support of industrials laboratories.

Abstract
OBJECTIVES Behçet disease (BD) is a chronic systemic inflammatory disorder of unknown aetiology. The aim of this study was to determine the orientation of T cell subpopulations in pediatric BD and more precisely to look for a regulatory T lymphocytes (Tregs)/Th17 imbalance. METHODS T cell subpopulations were analyzed by flow cytometry in the peripheral blood of pediatric patients with acute (aBD, n = 24), remitting (rBD, n = 12) BD, and in healthy controls (HC, n = 24). Tregs (CD4+CD25hiCD127-/loFoxp3+), activated Tregs (GITR, LAP, CTLA-4, and HLA-DR expression), CD4+ and CD8+ T cells producing interferon-g (Th1 and Tc1) or interleukin (IL)-17 (Th17 and Tc17) under polyclonal (OKT3/IL-2) or antigenic (Streptococcus sanguis KTH-1 peptides and HSP-60) stimulation, were numerated. RESULTS Th17 (1.9 and 5.1 fold) and Tc17 (4.0 and 2.0 fold) frequency under mitogenic stimulation was significantly increased in aBD and rBD patients as compared with HC. Th17 frequency under antigenic stimulation was also higher in patients than in HC. The percentage and number of Tregs and activated Tregs in patients and in HC were similar. However, when Tregs were removed, antigen-driven differentiation into Th1 and Th17 was significantly boosted in BD but not in HC CD4+T cells. CONCLUSION There is a bias toward a Th17 polarization in acute and remitting BD children. Although we did not observe an increase in the number of Tregs in these patients, their Tregs limit CD4+T cell differentiation into Th1 and Th17 cells. Thus, in pediatric BD, Tregs seem to incompletely counterbalance a Th17 orientation of the helper T cell response.

Abstract
Purpose During the alirocumab open-label extension study ODYSSEY OLE (open-label extension; NCT01954394), physicians could adjust alirocumab dosing for enrolled patients, who were diagnosed with heterozygous familial hypercholesterolemia (HeFH) and who had completed previous phase III clinical trials with alirocumab. This post hoc analysis evaluated the differences in physician–patient dosing decisions between the regions of Western Europe, Eastern Europe, North America, and the rest of the world (ROW). Methods Patients (n = 909) who received starting dose alirocumab 75 mg every 2 weeks (Q2W) during ODYSSEY OLE (patients from FH I, FH II, and LONG TERM parent studies) were included. Low-density lipoprotein cholesterol (LDL-C) levels were blinded until week 8; subsequently, LDL-C values were communicated to physicians. From week 12, dose adjustment from 75 to 150 mg Q2W, or vice versa, was possible. Results Mean LDL-C values used for the decision to increase dose from 75 to 150 mg Q2W were higher in Eastern Europe (3.7 mmol/L; 144.0 mg/dL) and ROW (3.8 mmol/L; 145.2 mg/dL) compared with Western Europe (3.1 mmol/L; 118.6 mg/dL) and North America (3.3 mmol/L; 126.6 mg/dL). Irrespective of region, the mean LDL-C at the time of decision to maintain at 75 mg Q2W was approximately 1.8 mmol/L (70 mg/dL). During ODYSSEY OLE (median treatment duration of 131.7 weeks), alirocumab was shown to have no unexpected long-term safety concerns. Conclusions In this OLE study, the observed variations in clinical treatment decisions suggest that physicians may perceive the severity of HeFH and/or the treatment of HeFH differently depending on their region.

Abstract
Abstract
Aims
To obtain safety and efficacy data of alirocumab, a proprotein convertase subtilisin/kexin type 9 inhibitor, in a real-life setting in high cardiovascular (CV) risk patients with heterozygous familial hypercholesterolaemia (HeFH) or very-high low-density lipoprotein cholesterol (LDL-C) levels despite maximally tolerated dose of statin ± other lipid-lowering therapies (MTD ± LLTs). ODYSSEY APPRISE was a prospective, single-arm, Phase 3b open-label (≥12 weeks to ≤ 30 months) European/Canadian study with alirocumab.
Methods and results
Patients received alirocumab 75 or 150 mg every 2 weeks, with dose adjustment based on physician’s judgment. In total, 994 patients were enrolled and treated. The mean [standard deviation (SD)] duration of alirocumab exposure was 72.4 (42.5) weeks. Patients with HeFH were younger [mean (SD) age of 53.8 (11.6) vs. 61.6 (10.1) years], more likely to be female (41.7% vs. 29.1%) and had higher baseline LDL-C compared with non-familial hypercholesterolaemia (non-FH) patients [mean (SD) of 5.1 (1.7) vs. 4.1 (1.1) mmol/L]. The overall incidence of treatment-emergent adverse events (TEAEs) was 71.6%; common TEAEs included nasopharyngitis (7.8%), myalgia (7.1%), and headache (6.2%). At Week 12, mean (SD) LDL-C was reduced by 54.8 (20.1)% from baseline [2.6 (1.2) mmol/L], maintained for the trial duration. LDL-C was reduced below 1.8 mmol/L and/or by ≥50% reduction from baseline in 69.1% of patients overall, and for 64.7 and 77.4% of the HeFH and non-FH subgroups, respectively.
Conclusion
In a real-life setting in patients with hypercholesterolaemia and high CV risk, alirocumab was generally well tolerated and resulted in clinically significant LDL-C reductions.

Abstract
BACKGROUND Patients with acute coronary syndrome (ACS) and history of coronary artery bypass grafting (CABG) are at high risk for recurrent cardiovascular events and death. OBJECTIVES This study sought to determine the clinical benefit of adding alirocumab to statins in ACS patients with prior CABG in a pre-specified analysis of ODYSSEY OUTCOMES (Evaluation of Cardiovascular Outcomes After an Acute Coronary Syndrome During Treatment With Alirocumab). METHODS Patients (n = 18,924) 1 to 12 months post-ACS with elevated atherogenic lipoprotein levels despite high-intensity statin therapy were randomized to alirocumab or placebo subcutaneously every 2 weeks. Median follow-up was 2.8 years. The primary composite endpoint of major adverse cardiovascular events (MACE) comprised coronary heart disease death, nonfatal myocardial infarction, ischemic stroke, or unstable angina requiring hospitalization. All-cause death was a secondary endpoint. Patients were categorized by CABG status: no CABG (n = 16,896); index CABG after qualifying ACS, but before randomization (n = 1,025); or CABG before the qualifying ACS (n = 1,003). RESULTS In each CABG category, hazard ratios (95% confidence intervals) for MACE (no CABG 0.86 [0.78 to 0.95], index CABG 0.85 [0.54 to 1.35], prior CABG 0.77 [0.61 to 0.98]) and death (0.88 [0.75 to 1.03], 0.85 [0.46 to 1.59], 0.67 [0.44 to 1.01], respectively) were consistent with the overall trial results (0.85 [0.78 to 0.93] and 0.85 [0.73 to 0.98], respectively). Absolute risk reductions (95% confidence intervals) differed across CABG categories for MACE (no CABG 1.3% [0.5% to 2.2%], index CABG 0.9% [-2.3% to 4.0%], prior CABG 6.4% [0.9% to 12.0%]) and for death (0.4% [-0.1% to 1.0%], 0.5% [-1.9% to 2.9%], and 3.6% [0.0% to 7.2%]). CONCLUSIONS Among patients with recent ACS and elevated atherogenic lipoproteins despite intensive statin therapy, alirocumab was associated with large absolute reductions in MACE and death in those with CABG preceding the ACS event.

Abstract
Aims Guidelines recommend targeting non-high-density lipoprotein cholesterol to reduce
cardiovascular risk. We assessed the impact of baseline triglycerides on
non-high-density lipoprotein cholesterol goal attainment in 10 phase 3 trials with
alirocumab versus control (n = 4983). Methods Trials were grouped into four pools based on alirocumab dose (75–150 mg every 2 weeks),
control (placebo/ezetimibe) and statin use. Baseline triglyceride quintiles were built
within each pool. Non-high-density lipoprotein cholesterol goal attainment (very high
risk: <100 mg/dl; moderate/high risk: <130 mg/dl), low-density lipoprotein
cholesterol goal attainment (very high risk: <70 mg/dl; moderate/high risk:
<100 mg/dl) and changes from baseline in lipid parameters were assessed at Week 24
among baseline triglyceride quintiles. Results Higher baseline triglycerides were associated with a worse cardiovascular risk profile.
Low-density lipoprotein cholesterol and non-high-density lipoprotein cholesterol
increased with higher triglycerides, but the magnitude in non-high-density lipoprotein
cholesterol was three- to four-fold higher compared with the increase in low-density
lipoprotein cholesterol. Non-high-density lipoprotein cholesterol and low-density
lipoprotein cholesterol percentage reductions from baseline with alirocumab were similar
regardless of baseline triglycerides. A greater proportion of alirocumab-treated
patients attained non-high-density lipoprotein cholesterol and low-density lipoprotein
cholesterol goals compared with placebo or ezetimibe. Unlike low-density lipoprotein
cholesterol goal attainment, non-high-density lipoprotein cholesterol goal attainment
significantly declined with increasing baseline triglycerides
(p < 0.05 for trend tests). A single standard deviation increase in
baseline log(triglycerides) was significantly associated with lower odds ratios of
attaining non-high-density lipoprotein cholesterol goals in the different pools and
treatment (alirocumab/placebo/ezetimibe) groups, unlike low-density lipoprotein
cholesterol goal attainment. Conclusion Individuals with increased triglycerides have higher non-high-density lipoprotein
cholesterol levels and lower rates of non-high-density lipoprotein cholesterol goal
attainment (unlike low-density lipoprotein cholesterol goal attainment). Alirocumab
improves non-high-density lipoprotein cholesterol goal attainment in this population.
These results highlight the impact of triglycerides on non-high-density lipoprotein
cholesterol and the need for novel therapies targeting triglyceride-related
pathways.

Effect of alirocumab on individuals with type 2 diabetes, high triglycerides, and low high-density lipoprotein cholesterol. Cardiovasc Diabetol 2020; 19:14. [PMID: 32035487 PMCID: PMC7007683 DOI: 10.1186/s12933-020-0991-1] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2019] [Accepted: 01/22/2020] [Indexed: 01/17/2023] Open
Abstract
BACKGROUND Mixed dyslipidemia [elevated non-high-density lipoprotein cholesterol (non-HDL-C) and triglycerides (TGs), and decreased HDL-C] is common in type 2 diabetes mellitus (T2DM) and is associated with increased cardiovascular risk. Non-HDL-C and apolipoprotein B (ApoB) are the preferred therapeutic targets for mixed dyslipidemia. Alirocumab is a monoclonal antibody to proprotein convertase subtilisin/kexin type 9 (PCSK9) that effectively reduces low-density lipoprotein cholesterol (LDL-C), non-HDL-C, ApoB, and lipoprotein(a) (Lp[a]), and is well-tolerated in individuals with T2DM. METHODS The previously reported open-label ODYSSEY DM-DYSLIPIDEMIA trial data demonstrated the effects of alirocumab on individuals with non-HDL-C ≥ 100 mg/dL and TGs ≥ 150 and < 500 mg/dL receiving stable maximally tolerated statin (n = 413). This post hoc subgroup analysis of the primary trial investigated the effects of alirocumab [75 mg every 2 weeks (Q2W) with possible increase to 150 mg Q2W at Week 12] versus usual care [ezetimibe, fenofibrate, or no additional lipid-lowering therapy (LLT)] on non-HDL-C and other lipids in individuals with T2DM and baseline TGs ≥ 200 mg/dL and HDL-C < 40 mg/dL (men) or < 50 mg/dL (women). RESULTS Alirocumab significantly reduced non-HDL-C [LS mean difference (standard error (SE)), - 35.0% (3.9)], ApoB [LS mean difference (SE), - 34.7% (3.6)], LDL-C [LS mean difference (SE), - 47.3% (5.2)], LDL particle number [LS mean difference (SE), - 40.8% (4.1)], and Lp(a) [LS mean difference (SE), - 29.9% (5.4)] versus usual care from baseline to Week 24 (all P < 0.0001). Results were similar for alirocumab versus usual care. TG reductions were similar between alirocumab and usual care (no significant difference), but greater with fenofibrate versus alirocumab (P = 0.3371). Overall, alirocumab significantly increased HDL-C versus usual care [LS mean difference (SE), 7.9% (3.6); P < 0.05], although differences with alirocumab versus ezetimibe or fenofibrate were non-significant. Most individuals receiving alirocumab achieved ApoB < 80 mg/dL (67.9%) and non-HDL-C < 100 mg/dL (60.9%). Adverse event frequency was similar between alirocumab (67.2%) and usual care (70.7%). Additionally, no clinically relevant effect of alirocumab on change in glycemic parameters or use of antihyperglycemic agents was observed. CONCLUSIONS Alirocumab is an effective therapeutic option for individuals with T2DM, TGs ≥ 200 mg/dL, and HDL-C < 40 mg/dL (men) or < 50 mg/dL (women). Atherogenic lipid (ApoB and non-HDL) reductions were greater with alirocumab than ezetimibe, fenofibrate, or no LLT. Consistent with previous studies, alirocumab was generally well tolerated.

Ocular symptoms improvement from intranasal triamcinolone compared with placebo and intranasal fluticasone propionate: A meta-analysis. Ann Allergy Asthma Immunol 2020; 124:616-621.e3. [PMID: 32004698 DOI: 10.1016/j.anai.2020.01.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2019] [Revised: 01/15/2020] [Accepted: 01/19/2020] [Indexed: 10/25/2022]
Abstract
BACKGROUND Allergic rhinitis is a prevalent disease, which can be classed as seasonal (SAR) or perennial. In addition to nasal symptoms, up to 75% of sufferers experience itching, redness, and tearing of the eyes. Intranasal corticosteroids are effective in controlling the allergic nasal symptoms, and increasing evidence suggests that they also can relieve some of the allergic ocular symptoms. OBJECTIVE To evaluate the magnitude of efficacy of triamcinolone acetonide (TAA) compared with placebo or fluticasone propionate (FP) on ocular symptom improvement in patients with SAR. METHODS A meta-analysis of summary data from 8 randomized, double- or single-blind trials, assessing mean change in total or individual (tearing, redness, and itching) eye symptoms was conducted. Trials that administered a daily dose of 220 μg TAA vs placebo or 200 μg FP over at least 2 weeks' duration, in patients aged 12 years or older with SAR, were analyzed. RESULTS Total eye symptom reduction after 2 weeks was greater with TAA than placebo, with a mean treatment difference of -0.32 (95% CI, -0.444 to -0.203). In addition, significant reductions in tearing, but not itching or redness, were observed after TAA treatment compared with placebo. No significant treatment difference was seen between TAA and FP in total ocular symptoms at any of the time points measured (weeks 1, 2, 3, and overall). All treatments exhibited similar safety profiles and were deemed well tolerated. CONCLUSION The meta-analysis demonstrated the positive clinical improvements TAA has on total ocular allergy symptoms, especially tearing, in addition to its recognized nasal symptom efficacy in SAR.

Lower On-Treatment Low-Density Lipoprotein Cholesterol and Major Adverse Cardiovascular Events in Women and Men: Pooled Analysis of 10 ODYSSEY Phase 3 Alirocumab Trials. J Am Heart Assoc 2019; 7:e009221.

Abstract
Background In statin trials, men and women derived similar relative risk reductions in cardiovascular events per 39 mg/dL low‐density lipoprotein cholesterol (LDL‐C) reduction. We explored whether lower LDL‐C levels and greater LDL‐C percentage reductions than those achieved with statins are associated with reduced major adverse cardiovascular event (MACE) rates in women as well as men. Methods and Results Data pooled from 10 phase 3 ODYSSEY randomized trials (n=4983) comparing alirocumab with control (placebo/ezetimibe) were assessed for association between 39 mg/dL lower on‐treatment LDL‐C and percentage LDL‐C change from baseline, and MACE risk by sex, using multivariable Cox regression. Mean baseline LDL‐C was 135 mg/dL (women) and 121 mg/dL (men). Average on‐treatment LDL‐C levels with alirocumab, ezetimibe, and placebo were 71, 114, and 134 mg/dL, respectively, in women (n=1882) and 52, 93, and 122 mg/dL, respectively, in men (n=3090). Overall, 36.5% and 58.7% of women and men, respectively, achieved on‐treatment LDL‐C <50 mg/dL. Each 39 mg/dL lower LDL‐C was associated with a 33% and 22% lower risk of MACE in women (P=0.0209) and men (P=0.0307), respectively, with no significant between‐sex difference (P for heterogeneity=0.4597). Results were similar when analyzed per 50% LDL‐C reduction, 24% (P=0.1094) and 29% (P=0.0125) lower MACE risk in women and men, respectively (P for heterogeneity=0.7499). Alirocumab was generally well tolerated in both sexes. Conclusions The present analysis reinforces the notion that both sexes derive a similar cardiovascular benefit from LDL‐C lowering. Although women had slightly higher on‐treatment LDL‐C than men, both sexes showed a similar lower MACE risk with lower LDL‐C.

Abstract
BACKGROUND Age, smoking, hypercholesterolemia, and hypertension are major risk factors for atherosclerotic cardiovascular disease. OBJECTIVE We examined whether the effects of alirocumab on low-density lipoprotein cholesterol (LDL-C) differed according to age, hypertension, or smoking status. METHODS Data were pooled from 10 Phase 3 ODYSSEY randomized trials (24-104 weeks' duration) in 4983 people with heterozygous familial hypercholesterolemia (FH) or non-familial hypercholesterolemia (3188 on alirocumab, 1795 on control [620 on ezetimibe and 1175 on placebo]). Most participants received concomitant maximum tolerated statin therapy. In 8 trials, the alirocumab dose was increased from 75 mg every 2 weeks (Q2W) to 150 mg Q2W at Week 12 if predefined risk-based LDL-C goals were not achieved at Week 8 (≥70 mg/dL in very high cardiovascular risk; ≥100 mg/dL in moderate or high cardiovascular risk). Two trials compared alirocumab 150 mg Q2W vs placebo. The efficacy and safety of alirocumab were assessed post hoc in subgroups stratified by age (<65, ≥65 to <75, ≥75 years) and baseline hypertension or smoking status. RESULTS Alirocumab reduced LDL-C by 23.7% (75/150 mg vs ezetimibe + statin) to 65.4% (150 mg vs placebo + statin) from baseline to Week 24 vs control. Subgroup analyses confirmed no significant interactions in response to alirocumab between age group, hypertension, or smoking status. Overall rates of treatment-emergent adverse events were similar between alirocumab and control groups. CONCLUSIONS In this pooled analysis from 10 trials, alirocumab led to substantial LDL-C reductions vs control in every age group and regardless of hypertension or smoking status. Alirocumab was well tolerated in all subgroups.

Associations between lower levels of low-density lipoprotein cholesterol and cardiovascular events in very high-risk patients: Pooled analysis of nine ODYSSEY trials of alirocumab versus control. Atherosclerosis 2019; 288:85-93. [PMID: 31349086 DOI: 10.1016/j.atherosclerosis.2019.07.008] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/08/2019] [Revised: 06/26/2019] [Accepted: 07/10/2019] [Indexed: 11/18/2022]
Abstract
BACKGROUND AND AIMS Guidelines recommend high-intensity statins for patients with atherosclerotic cardiovascular disease (ASCVD). Subgroups with comorbidities that increase cardiovascular risk, such as diabetes mellitus (DM), chronic kidney disease (CKD) or polyvascular disease (PoVD), may derive greater absolute benefit from addition of non-statin therapies. We assessed the relationship between lower low-density lipoprotein cholesterol (LDL-C) and major adverse cardiovascular events (MACE) risk reduction during alirocumab phase III ODYSSEY trials among these subgroups. METHODS Patient data were pooled from nine trials comparing alirocumab with control (placebo/ezetimibe), predominantly on background maximally tolerated statin. Patients with baseline ASCVD were stratified into subgroups with DM, CKD or PoVD, or without comorbidities, and between-group relative and absolute benefits were compared. RESULTS Among 3505 patients with ASCVD, 1573 had no comorbidities, 981 had DM, 660 had CKD and 943 had PoVD, with overlap between comorbidities; mean baseline LDL-C levels were 119 (ASCVD overall), 123, 117, 114 and 113 mg/dL, respectively. Overall, each 39 mg/dL lower on-study LDL-C was associated with a 25% lower MACE risk, hazard ratio 0.75 (95% confidence interval, 0.62-0.90, p = 0.0023), with a similar lower risk observed in each very high-risk subgroup (DM, CKD or PoVD; 30-35%) but not in the subgroup without these comorbidities (9%). Absolute benefits were greater for very high-risk subgroups; lowering LDL-C from 120 to 40 mg/dL would result in 2.76-4.35 fewer MACE/100 patient-years versus 0.3 for no comorbidities. CONCLUSIONS Among patients with ASCVD and mean baseline LDL-C >100 mg/dL, patients with DM, CKD or PoVD appeared to derive greater absolute cardiovascular benefits from further LDL-C reduction than those without.

PCSK9 inhibition in patients with and without prior myocardial infarction or ischemic stroke: A pooled analysis of nine randomized-controlled studies of alirocumab. J Clin Lipidol 2019; 13:443-454. [PMID: 31076261 DOI: 10.1016/j.jacl.2019.04.005] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2018] [Revised: 03/01/2019] [Accepted: 04/02/2019] [Indexed: 01/05/2023]
Abstract
BACKGROUND Patients with prior cardiovascular events are at very high risk of recurrent events and may benefit from low-density lipoprotein cholesterol (LDL-C) lowering beyond that achieved with maximally tolerated statins. OBJECTIVE To assess potential differences between the efficacy and safety of the proprotein convertase subtilisin/kexin type 9 inhibitor, alirocumab, in patients with vs without prior myocardial infarction (MI)/ischemic stroke. METHODS Data (n = 4880) were pooled from nine ODYSSEY phase 3 trials of alirocumab 75/150 mg or 150 mg every 2 weeks, mostly on background statins ± other lipid-lowering therapies. Analyses were performed according to statin status, alirocumab dose, and control (placebo or ezetimibe). RESULTS Baseline LDL-C, non-high-density lipoprotein cholesterol, high-density lipoprotein cholesterol, and apolipoprotein B levels were lower and lipoprotein(a) higher in patients with than without prior MI/ischemic stroke. LDL-C levels were reduced from baseline to week 24 in patients with (51.1%-62.9%) and without (43.6%-58.3%) prior MI/ischemic stroke, with no significant interaction between prior MI/ischemic stroke status and LDL-C-lowering efficacy of alirocumab vs controls. Alirocumab significantly reduced other lipid/lipoproteins (including lipoprotein[a]) similarly in patients with/without MI/ischemic stroke. Week 24 LDL-C goal attainment rates for subgroups with/without prior MI/ischemic stroke on background statins were 74.1%-84.8% and 63.7%-74.7%, respectively. The safety profile of alirocumab was generally similar regardless of prior MI/ischemic stroke status. CONCLUSIONS Alirocumab significantly reduced LDL-C and other atherogenic lipids/lipoproteins in patients with prior MI/ischemic stroke, and the majority of this very high cardiovascular risk population achieved LDL-C goals; efficacy and safety results were similar in patients without prior MI/ischemic stroke.

Abstract
AIM To evaluate the safety of the proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor alirocumab according to diabetes mellitus status. METHODS Safety data from 14 trials (8-104-week durations) were analysed by treatment (alirocumab or placebo/ezetimibe control) and diabetes status (yes/no, defined by medical history). Adverse event data were assessed using descriptive statistics and Cox models. RESULTS Of the 5234 trial participants, 1554 (29.7%) had diabetes. Overall, treatment-emergent adverse events were similar in the alirocumab and control groups, except for more frequent local injection site reactions with alirocumab. Fewer people with diabetes experienced local injection site reactions [alirocumab, 3.5%, control, 2.9%; hazard ratio 1.24 (95% CI 0.68-2.25)] than those without diabetes [alirocumab, 7.5%; control, 4.9%; hazard ratio 1.51 (95% CI 1.13-2.01)]. Those with diabetes reported a greater number of serious adverse events (alirocumab, 19.4%; control, 19.7%) than those without diabetes (alirocumab, 14.5%; control, 13.5%). In people with diabetes, major adverse cardiac events occurred in 2.7% of alirocumab-treated people [control, 3.3%; hazard ratio 0.74 (95% CI 0.41-1.35)]; in those without diabetes, 1.8% of alirocumab-treated people had major adverse cardiac events [control, 1.7%; hazard ratio 0.95 (95% CI 0.56-1.62)]. Overall, no increase in HbA1c or fasting plasma glucose vs control treatment groups was observed, regardless of diabetes status. CONCLUSION This pooled analysis across 14 trials demonstrated similar safety for alirocumab vs control treatment, irrespective of diabetes status, except for more frequent local injection site reactions with alirocumab. People with diabetes reported fewer local injection site reactions than those without diabetes.

Efficacy and safety of alirocumab among individuals with diabetes mellitus and atherosclerotic cardiovascular disease in the ODYSSEY phase 3 trials. Diabetes Obes Metab 2018; 20:2389-2398. [PMID: 29802688 PMCID: PMC6175384 DOI: 10.1111/dom.13384] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2018] [Revised: 05/14/2018] [Accepted: 05/23/2018] [Indexed: 12/22/2022]
Abstract
AIMS Individuals with both diabetes mellitus (DM) and atherosclerotic cardiovascular disease (ASCVD) are at very high risk of cardiovascular events. This post-hoc analysis evaluated efficacy and safety of the PCSK9 inhibitor alirocumab among 984 individuals with DM and ASCVD pooled from 9 ODYSSEY Phase 3 trials. MATERIALS AND METHODS Changes in low-density lipoprotein cholesterol (LDL-C) and other lipids from baseline to Week 24 were analysed (intention-to-treat) in four pools by alirocumab dosage (150 mg every 2 weeks [150] or 75 mg with possible increase to 150 mg every 2 weeks [75/150]), control (placebo/ezetimibe) and background statin usage (yes/no). RESULTS At Week 24, LDL-C changes from baseline in pools with background statins were -61.5% with alirocumab 150 (vs -1.0% with placebo), -46.4% with alirocumab 75/150 (vs +6.3% with placebo) and -48.7% with alirocumab 75/150 (vs -20.6% with ezetimibe), and -54.9% with alirocumab 75/150 (vs +4.0% with ezetimibe) without background statins. A greater proportion of alirocumab recipients achieved LDL-C < 70 and < 55 mg/dL at Week 24 vs controls. Alirocumab also resulted in significant reductions in non-high-density lipoprotein cholesterol, apolipoprotein B and lipoprotein(a) vs controls. Alirocumab did not appear to affect glycaemia over 78-104 weeks. Overall safety was similar between treatment groups, with a higher injection-site reaction frequency (mostly mild) with alirocumab. CONCLUSION Alirocumab significantly reduced LDL-C and other atherogenic lipid parameters, and was generally well tolerated in individuals with DM and ASCVD.

Abstract
BACKGROUND AND AIMS Alirocumab, a monoclonal antibody to proprotein convertase subtilisin/kexin type 9, significantly reduces low-density lipoprotein cholesterol (LDL-C). We evaluated the efficacy and safety of alirocumab in individuals with type 2 diabetes mellitus (T2DM) with versus without mixed dyslipidaemia (MDL, defined as baseline LDL-C ≥70 mg/dL [1.8 mmol/L] and triglycerides ≥150 mg/dL [1.7 mmol/L]). METHODS Data from 812 individuals with T2DM, from the placebo-controlled, 78-week, Phase 3 ODYSSEY LONG TERM trial of alirocumab 150 mg every 2 weeks (Q2W), on a background of maximally tolerated statins ± other lipid-lowering therapies, were pooled according to MDL status. Efficacy endpoints included percentage change from baseline to Week 24 in calculated LDL-C and other lipids/lipoproteins. RESULTS In individuals with T2DM who received alirocumab 150 mg Q2W, mean LDL-C changes from baseline to Week 24 were -62.6% (vs. -6.0% with placebo) in those with MDL and -56.1% (vs. 5.6%) in those without MDL, with no significant between-group difference (p-interaction = 0.0842). Risk-based LDL-C goals (<70 [1.8 mmol/L] or <100 mg/dL [2.6 mmol/L]) were achieved by 69.1% and 72.4% of alirocumab-treated individuals with and without MDL, respectively. Mean reductions in non-high-density lipoprotein cholesterol (49.2% and 47.8%) and apolipoprotein B (50.2% and 49.1%) with alirocumab were also similar in those with and without MDL, respectively. Treatment-emergent adverse event rates were comparable between alirocumab-treated individuals with T2DM, with and without MDL. CONCLUSIONS Reductions in LDL-C and other lipids with alirocumab, as well as safety and tolerability, were comparable between individuals with T2DM and with versus without MDL.

Effect of alirocumab on lipids and lipoproteins in individuals with metabolic syndrome without diabetes: Pooled data from 10 phase 3 trials. Diabetes Obes Metab 2018; 20:1632-1641. [PMID: 29493859 PMCID: PMC6033097 DOI: 10.1111/dom.13273] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/10/2017] [Revised: 02/16/2018] [Accepted: 02/25/2018] [Indexed: 01/23/2023]
Abstract
AIMS This analysis assessed the efficacy and safety of alirocumab, a proprotein convertase subtilisin/kexin type 9 inhibitor, in patients with or without metabolic syndrome (MetS) using pooled data from 10 phase 3 ODYSSEY trials. MATERIALS AND METHODS Data from 4983 randomized patients (1940 with MetS; 1642 with diabetes excluded) were assessed in subgroups by MetS status. Efficacy data were analysed in 4 pools per study design: 2 placebo-controlled pools (1 using alirocumab 150 mg every 2 weeks [Q2W], 1 using 75/150 mg Q2W) with background statin, and 2 ezetimibe-controlled pools (both alirocumab 75/150 mg Q2W), 1 with and 1 without background statin. Alirocumab 75/150 mg indicates possible dose increase from 75 to 150 mg at Week 12 based on Week 8 LDL-C. RESULTS LDL-C percentage reduction from baseline at Week 24 with alirocumab was 63.9% (MetS) and 56.8% (non-MetS) in the pool of alirocumab 150 mg Q2W, and 42.2% to 52.2% (MetS) and 45.0% to 52.6% (non-MetS) in 3 pools using 75/150 mg Q2W. Levels of other lipid and lipoprotein parameters were also improved with alirocumab treatment, including apolipoprotein B, non-high-density lipoprotein cholesterol (non-HDL-C), lipoprotein(a) and HDL-C. Overall, the percentage change at Week 24 in LDL-C and other lipids and lipoproteins did not vary by MetS status. Adverse event rates were generally similar between treatment groups, regardless of MetS status; injection-site reactions occurred more frequently in alirocumab vs control groups. CONCLUSIONS Across study pools, alirocumab-associated reductions in LDL-C, apolipoprotein B, and non-HDL-C were significant vs control, and did not vary by MetS status.

Alirocumab vs usual lipid-lowering care as add-on to statin therapy in individuals with type 2 diabetes and mixed dyslipidaemia: The ODYSSEY DM-DYSLIPIDEMIA randomized trial. Diabetes Obes Metab 2018; 20:1479-1489. [PMID: 29436756 PMCID: PMC5969299 DOI: 10.1111/dom.13257] [Citation(s) in RCA: 65] [Impact Index Per Article: 10.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2017] [Revised: 01/29/2018] [Accepted: 02/06/2018] [Indexed: 01/14/2023]
Abstract
AIM To compare alirocumab, a proprotein convertase subtilisin-kexin type 9 inhibitor, with usual care (UC) in individuals with type 2 diabetes (T2DM) and mixed dyslipidaemia not optimally managed by maximally tolerated statins in the ODYSSEY DM-DYSLIPIDEMIA trial (NCT02642159). MATERIALS AND METHODS The UC options (no additional lipid-lowering therapy; fenofibrate; ezetimibe; omega-3 fatty acid; nicotinic acid) were selected prior to stratified randomization to open-label alirocumab 75 mg every 2 weeks (with increase to 150 mg every 2 weeks at week 12 if week 8 non-HDL cholesterol concentration was ≥2.59 mmol/L [100 mg/dL]) or UC for 24 weeks. The primary efficacy endpoint was percentage change in non-HDL cholesterol from baseline to week 24. RESULTS The randomized population comprised 413 individuals (intention-to-treat population, n = 409; safety population, n = 412). At week 24, the mean non-HDL cholesterol reductions were superior with alirocumab (-32.5% difference vs UC, 97.5% confidence interval -38.1 to -27.0; P < .0001). Overall, 63.6% of alirocumab-treated individuals were maintained on 75 mg every 2 weeks. Alirocumab also reduced LDL cholesterol (-43.0%), apolipoprotein B (-32.3%), total cholesterol (-24.6%) and LDL particle number (-37.8%) at week 24 vs UC (all P < .0001). Consistent with the overall trial comparison, alirocumab reduced non-HDL cholesterol to a greater degree within each UC stratum at week 24. The incidence of treatment-emergent adverse events was 68.4% (alirocumab) and 66.4% (UC). No clinically meaningful effect on glycated haemoglobin, or change in number of glucose-lowering agents, was seen. CONCLUSIONS In individuals with T2DM and mixed dyslipidaemia on maximally tolerated statin, alirocumab showed superiority to UC in non-HDL cholesterol reduction and was generally well tolerated.

Abstract
INTRODUCTION Diabetes mellitus (DM) carries an elevated risk for cardiovascular disease. Here, we assessed alirocumab efficacy and safety in people with/without DM from five placebo-controlled phase 3 studies. METHODS Data from up to 78 weeks were analyzed in individuals on maximally tolerated background statin. In three studies, alirocumab 75 mg every 2 weeks (Q2W) was increased to 150 mg Q2W at week 12 if week 8 low-density lipoprotein cholesterol (LDL-C) was ≥ 70 mg/dL; two studies used alirocumab 150 mg Q2W throughout. The primary endpoint was percentage change in LDL-C from baseline to week 24. RESULTS In the alirocumab 150 mg pool (n = 2416), baseline LDL-C levels were 117.4 mg/dL (DM) and 130.6 mg/dL (without DM), and in the 75/150 mg pool (n = 1043) 112.8 mg/dL (DM) and 133.0 mg/dL (without DM). In the 150 mg Q2W group, week 24 LDL-C reductions from baseline were observed in persons with DM (- 59.9%; placebo, - 1.4%) and without DM (- 60.6%; placebo, + 1.5%); 77.7% (DM) and 76.8% (without DM) of subjects achieved LDL-C < 70 mg/dL. In the alirocumab 75/150 mg group, 26% (DM) and 36% (without DM) of subjects received dose increase. In this group, week 24 LDL-C levels changed from baseline by - 43.8% (DM; placebo, + 0.3%) and - 49.7% (without DM; placebo, + 5.1%); LDL-C < 70 mg/dL was achieved by 68.3% and 65.8% of individuals, respectively. At week 24, alirocumab was also associated with improved levels of other lipids. Adverse event rates were generally comparable in all groups (79.8-82.0%). CONCLUSIONS Regardless of DM status, alirocumab significantly reduced LDL-C levels; safety was generally similar. FUNDING Sanofi and Regeneron Pharmaceuticals, Inc.

Abstract
AIM To assess the lipid-lowering efficacy and safety of alirocumab, a proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor, in people with hypercholesterolaemia and prediabetes at baseline vs people with normoglycaemia at baseline in a pooled analysis of 10 ODYSSEY phase III trials. METHODS People classified as having prediabetes had baseline HbA1c ≥39 mmol/mol (5.7%) and <48 mmol/mol (6.5%), or two baseline fasting plasma glucose values ≥5.6 mmol/l (100 mg/dl) but no more than one fasting plasma glucose value ≥7.0 mmol/l (126 mg/dl), or had specific terms reported in their medical history; people diagnosed with diabetes at baseline were excluded, and the remainder were classified as having normoglycaemia. Participants received alirocumab or control (placebo/ezetimibe) for 24-104 weeks, with maximally tolerated statin in most cases. The primary efficacy endpoint was LDL cholesterol reductions from baseline to week 24 in the intention-to-treat population using the mixed-effect model with a repeated measures approach. RESULTS Reductions in LDL cholesterol from baseline to week 24 with alirocumab were 44.0-61.8% (prediabetes group) and 45.8-59.5% (normoglycaemia group). In both subgroups, LDL cholesterol reductions were generally similar in those with and without baseline triglycerides ≥1.7 mmol/l (150 mg/dl). Alirocumab was not associated with changes in HbA1c or fasting plasma glucose over time in either subgroup (up to 24 months' follow-up). Adverse event rates were generally similar in those with and without prediabetes. CONCLUSIONS Over a mean follow-up of 24-104 weeks, alirocumab treatment resulted in significant LDL cholesterol reductions from baseline that were similar in participants with prediabetes and those with normoglycaemia at baseline, with no effect on glycaemia and a safety profile similar to that of the control.

Abstract
Background Type 2 diabetes mellitus (T2DM) is often associated with mixed dyslipidaemia, where non-high-density lipoprotein cholesterol (non-HDL-C) levels may more closely align with cardiovascular risk than low-density lipoprotein cholesterol (LDL-C). We describe the design and rationale of the ODYSSEY DM-DYSLIPIDEMIA study that assesses the efficacy and safety of alirocumab, a proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor, versus lipid-lowering usual care in individuals with T2DM and mixed dyslipidaemia at high cardiovascular risk with non-HDL-C inadequately controlled despite maximally tolerated statin therapy. For the first time, atherogenic cholesterol-lowering with a PCSK9 inhibitor will be assessed with non-HDL-C as the primary endpoint with usual care as the comparator. Methods DM-DYSLIPIDEMIA is a Phase 3b/4, randomised, open-label, parallel group, multinational study that planned to enrol 420 individuals. Main inclusion criteria were T2DM and mixed dyslipidaemia (non-HDL-C ≥100 mg/dl [≥2.59 mmol/l], and triglycerides ≥150 and <500 mg/dl [≥1.70 and <5.65 mmol/l]) with documented atherosclerotic cardiovascular disease or ≥1 additional cardiovascular risk factor. Participants were randomised (2:1) to alirocumab 75 mg every 2 weeks (Q2W) or lipid-lowering usual care on top of maximally tolerated statin (or no statin if intolerant). If randomised to usual care, investigators were able to add their pre-specified choice of one of the following to the patient’s current statin regimen: ezetimibe, fenofibrate, omega-3 fatty acids or nicotinic acid, in accordance with local standard-of-care. Alirocumab-treated individuals with non-HDL-C ≥100 mg/dl at week 8 will undergo a blinded dose increase to 150 mg Q2W at week 12. The primary efficacy endpoint is non-HDL-C change from baseline to week 24 with alirocumab versus usual care; other lipid levels (including LDL-C), glycaemia-related measures, safety and tolerability will also be assessed. Alirocumab will be compared to fenofibrate in a secondary analysis. Results Recruitment completed with 413 individuals randomised in 14 countries worldwide. Results of this trial are expected in the second quarter of 2017. Conclusions ODYSSEY DM-DYSLIPIDEMIA will provide information on the efficacy and safety of alirocumab versus lipid-lowering usual care in individuals with T2DM and mixed dyslipidaemia at high cardiovascular risk using non-HDL-C as the primary efficacy endpoint.

Neuropsychological Impairment in Detoxified Alcohol-Dependent Subjects with Preserved Psychosocial Functioning. Front Psychiatry 2017; 8:193.

Abstract
BACKGROUND Chronic alcoholism and its related cognitive impairments are associated with increased social, relational, and professional deficits which have a variable overall impact on social integration. These impairments are known to have varying severities and have rarely been studied among healthy alcohol-dependent subjects with preserved psychosocial functioning. Thus, the objective of this study is to describe neuropsychological performance in this particular population. METHOD Twenty-nine socially adjusted alcohol-dependent men, hospitalized for a first or second withdrawal and abstinent for 3 weeks minimum, were compared to 29 healthy non-alcoholic controls. All subjects underwent clinical and psychiatric examination, neuropsychological tests of memory (M), working memory (WM), and executive functions (EF). Comparisons were performed using Student's t-tests or Mann-Whitney U tests. RESULTS No group differences were found on the Self-Reported Social Adjustment Scale (SAS-SR) or in the Mini-Mental State Examination. Compared to controls, patients had greater episodic, spatial, and WM deficits as well as slightly altered executive functions. In contrast, their executive functions (spontaneous flexibility, criteria generation, rule maintenance, and inhibitory control) were relatively preserved. CONCLUSION Our sample of socially and professionally integrated alcoholic patients shows fewer cognitive deficits than described in previous studies. Our results suggest that early on, alcohol-dependent subjects develop compensatory adaptation processes to preserve social function and adaptation. Minor cognitive impairments should be screened early in the disease to integrate cognitive interventions into the health-care plan to thus eventually prevent further socio-professional marginalization.

Abstract
AIM Little information is available regarding the influence of CYP3A5 genetic polymorphisms on tacrolimus dose requirement in pediatric liver transplantation. PATIENTS & METHODS We performed a retrospective study among 179 pediatric liver recipients grafted between 2002 and 2009 in order to determine the influence of donor CYP3A5 genotype along with clinical variables on tacrolimus daily dose requirement during the first weeks following transplantation. RESULTS Mean stable tacrolimus daily dose requirement was higher among children who received a liver expressing CYP3A5 (carrying the CYPA3A5*1 allele) compared with those with a liver that did not express CYP3A5 (CYP3A5*3/*3 genotype): 0.29 ± 0.20 vs 0.18 ± 0.13 mg.kg(-1).d(-1), p = 0.005, respectively. A younger recipient age and fluconazole prescription were also significantly associated with tacrolimus daily dose requirement. Time to reach stable tacrolimus therapeutic trough concentrations was prolonged among patients with a CYP3A5-expressing graft (26 vs 21 days, p = 0.04). CONCLUSION Donor CYP3A5 genotype partially explains tacrolimus dose requirement. Original submitted 30 January 2013; Revision submitted 2 May 2013.

Abstract
BACKGROUND Albumin dialysis with the Molecular Adsorbent Recirculating System (MARS) (Gambro, Lund, Sweden), a noncell artificial liver support device, may be beneficial in acute liver failure (ALF). OBJECTIVE To determine whether MARS improves survival in ALF. DESIGN Randomized, controlled trial. (ClinicalTrials.gov: NCT00224705). SETTING 16 French liver transplantation centers. PATIENTS 102 patients with ALF. INTERVENTION Conventional treatment (n = 49) or MARS with conventional treatment (n = 53), stratified according to whether paracetamol caused ALF. MEASUREMENTS 6-month survival and secondary end points, including adverse events. RESULTS 102 patients (mean age, 40.4 years [SD, 13]) were in the modified intention-to-treat (mITT) population. The per-protocol analysis (49 conventional, 39 MARS) included patients with at least 1 session of MARS of 5 hours or more. Six-month survival was 75.5% (95% CI, 60.8% to 86.2%) with conventional treatment and 84.9% (CI, 71.9% to 92.8%) with MARS (P = 0.28) in the mITT population and 75.5% (CI, 60.8% to 86.2%) with conventional treatment and 82.9% (CI, 65.9% to 91.9%) with MARS (P = 0.50) in the per-protocol population. In patients with paracetamol-related ALF, the 6-month survival rate was 68.4% (CI, 43.5% to 86.4%) with conventional treatment and 85.0% (CI, 61.1% to 96.0%) with MARS (P = 0.46) in the mITT population. Sixty-six of 102 patients had transplantation (41.0% among paracetamol-induced ALF; 79.4% among non-paracetamol-induced ALF) (P < 0.001). Adverse events did not significantly differ between groups. LIMITATION The short delay from randomization to liver transplantation (median, 16.2 hours) precludes definitive efficacy or safety evaluations. CONCLUSION This randomized trial of MARS in patients with ALF was unable to provide definitive efficacy or safety conclusions because many patients had transplantation before administration of the intervention. Acute liver failure not caused by paracetamol was associated with greater 6-month patient survival. PRIMARY FUNDING SOURCE Assistance Publique-Hôpitaux de Paris.

Abstract
BACKGROUND Hypercalciuria is frequent in patients with acromegaly, but it is unclear how GH/IGF-I regulate renal calcium handling. Elevated fasting plasma calcium levels despite increased glomerular filtration suggest enhanced renal calcium reabsorption. OBJECTIVE The aim of this study was to investigate the impact of acromegaly on phosphocalcium metabolism. DESIGN AND SETTING We conducted a prospective sequential study at a tertiary referral medical center and clinical investigation center (www.ClinicalTrials.gov Identifier: NCT00531908). INTERVENTION Sixteen consecutive patients (five females/11 males) with acromegaly received a single iv infusion of 25 mg of furosemide to induce an acute increase in calcium and magnesium delivery to distal tubular segments during a high-sodium diet with stable dietary calcium, magnesium, and phosphate intake. MEASUREMENTS Baseline plasma and urine electrolytes, plasma calciotropic hormones, and furosemide-induced changes in the fractional excretion and tubular reabsorption of Na, Ca, and Mg were measured before and 6 months (range, 1-12) after effective treatment of acromegaly. RESULTS Serum IGF-I concentrations normalized in all the patients after acromegaly treatment. Compared with controlled acromegaly, active acromegaly was associated with higher fasting plasma (P = 0.0002) and urinary calcium (P = 0.0003) levels, lower PTH levels (P = 0.0075), higher calcitriol levels (P = 0.0137), higher phosphatemia (P<0.0001) and tubular phosphate reabsorption (P = 0.0002), and a lower calciuric (P = 0.0327) but not magnesiuric response to furosemide related to higher baseline and postfurosemide tubular calcium (P = 0.0034 and P = 0.0081, respectively), but not magnesium reabsorption. CONCLUSION The IGF-I-mediated and PTH-independent increase in calcitriol synthesis in acromegaly is responsible for both absorptive hypercalciuria and increased fasting plasma calcium linked to enhanced distal tubular calcium reabsorption, as shown by the selectively diminished calciuric response to furosemide.

Abstract
BACKGROUND Soft-tissue swelling and increased extracellular volume, two features of acromegaly, are related to the antinatriuretic effects of excess GH/IGF-I, but the precise pathophysiological mechanism is unclear. OBJECTIVE Our objective was to determine the effect of the GH excess on renal and extrarenal epithelial sodium channel (ENaC) activity. DESIGN AND SETTING We conducted a prospective randomized open-label blinded-endpoint (PROBE) crossover study (www.ClinicalTrials.gov Identifier: NCT00531908) at a tertiary referral medical center and clinical investigation center. INTERVENTION Sixteen patients (five females, 11 males) with acromegaly were randomly assigned to receive 20 mg amiloride (an ENaC blocker) and 25 mg furosemide (a Na-K-2Cl cotransporter blocker) under a high-sodium diet to suppress endogenous renin and aldosterone. MEASUREMENTS Diuretic-induced changes in the urinary Na/K ratio (reflecting coupling between ENaC-mediated Na reabsorption and distal K secretion) and the intranasal amiloride-sensitive potential (reflecting extrarenal ENaC activity) were measured before and 6 months after (range, 1-12 months) treatment of acromegaly. RESULTS Serum IGF-I concentrations normalized in all the patients after treatment of acromegaly. Baseline plasma renin and aldosterone concentrations remained unchanged after treatment. Active acromegaly, compared with controlled disease, was associated with an enhanced response [median (interquartile range)] to amiloride [urinary Na/K, 13.9 (9.8-19.5) vs. 6.3 (4.3-8.4) mmol/mmol, P = 0.0003], a reduced response to furosemide [urinary Na/K, 5.2 (4.6-7.2) vs. 7.1 (5.4-8.8) mmol/mmol, P =0.0151], and an increased intranasal amiloride-sensitive potential [5.8 (11.9-3.8) vs. 4.2 (6.4-2.1) mV, P = 0.031], respectively. CONCLUSION GH/IGF-I excess in humans is associated with enhanced renal and extrarenal ENaC activity that may contribute to soft-tissue swelling and volume expansion in acromegaly.

Abstract
AIMS This study aimed to determine the influence of gene candidates on mycophenolic acid (MPA) response during the first year of renal transplantation. MATERIALS & METHODS A total of 218 renal transplant recipients who received MPA from the first day of transplantation at a fixed dose of 2 g/day were genotyped for ABCB1, ABCC2, UGT2B7, UGT1A9, SLCO1B1, SLCO1B3 and IMPDH1 polymorphisms. Clinical end points were MPA-related adverse drug reactions (ADRs) and acute rejection episodes during the first year post-transplantation. RESULTS After correction for multiple statistical testing, SLCO1B1 (encoding the hepatic uptake transporter OATP1B1) was the only gene associated with MPA-related ADRs, showing a 75% risk reduction in favor of a protective effect of the SLCO1B1*5 allele (p = 0.002). In vitro experiments showed that MPA metabolites MPA-phenyl-glucuronide and MPA-acyl-glucuronide are substrates of OATP1B1. Their transport was decreased in the presence of the variant transporter (OATP1B1*5). CONCLUSION These results suggest for the first time that carriers of the SLCO1B1*5 allele seem to be protected from MPA-related ADRs.

Abstract
OBJECTIVE To set-up an international cohort of patients suspected with Behçet's disease (BD). The cohort is aimed at defining an algorithm for definition of the disease in children. METHODS International experts have defined the inclusion criteria as follows: recurrent oral aphthosis (ROA) plus one of following-genital ulceration, erythema nodosum, folliculitis, pustulous/acneiform lesions, positive pathergy test, uveitis, venous/arterial thrombosis and family history of BD. Onset of disease is <16 years, disease duration is ≤3 years, future follow-up duration is ≥4 years and informed consent is obtained. The expert committee has classified the included patients into: definite paediatric BD (PED-BD), probable PED-BD and no PED-BD. Statistical analysis is performed to compare the three groups of patients. Centres document their patients into a single database. RESULTS At January 2010, 110 patients (56 males/54 females) have been included. Mean age at first symptom: 8.1 years (median 8.2 years). At inclusion, 38% had only one symptom associated with ROA, 31% had two and 31% had three or more symptoms. A total of 106 first evaluations have been done. Seventeen patients underwent the first-year evaluation, and 36 had no new symptoms, 12 had one and 9 had two. Experts have examined 48 files and classified 30 as definite and 18 as probable. Twenty-six patients classified as definite fulfilled the International Study Group criteria. Seventeen patients classified as probable did not meet the international criteria. CONCLUSION The expert committee has classified the majority of patients in the BD group although they presented with few symptoms independently of BD classification criteria.

Abstract
The authors studied the psychosocial adjustment of pediatric liver transplant (LT) recipients reaching adulthood. The study comprised phone interviews of 116 volunteers aged 17-33 years. Results were compared to those for healthy peers and 65 patients who were eligible for inclusion but did not participate. Participants' median age at LT was 6 years and the median period since LT was 15 years. Of the 116 participants, 76% considered their quality of life as good or very good. Seventy-five patients (65%) were attending schools, 27 of whom were 2 years or more below the age-appropriate level. Of the remaining 41 patients, 26 had a job and 15 were unemployed. Poor compliance with medications was reported by 52 patients (45%). Alcohol consumption was lower than in the reference population (p < 0.001). Anxiety, loneliness and negative thoughts were expressed by 53, 84 and 47% of the participants, respectively. Thirteen patients (11%) were being cared for by psychologists or psychiatrists. The 65 nonparticipants had greater psychological problems than the participants, and a lower educational level. In conclusion, after LT in early life, most patients displayed psychological vulnerability during early adulthood. The educational level of patients was lower than that of theirs peers.
