Background Simplified regimens with reduced pill burden and fewer side-effects are desirable for people living with HIV. We investigated the efficacy and safety of switching to a single-tablet regimen of darunavir, cobicistat, emtricitabine, and tenofovir alafenamide versus continuing a regimen of boosted protease inhibitor, emtricitabine, and tenofovir disoproxil fumarate. Methods EMERALD was a phase-3, randomised, active-controlled, open-label, international, multicentre trial, done at 106 sites across nine countries in North America and Europe. HIV-1-infected adults were eligible to participate if they were treatment-experienced and virologically suppressed (viral load = 2 months; one viral load of 50-200 copies per mL was allowed within 12 months before screening), and patients with a history of virological failure on non-darunavir regimens were allowed. Randomisation was by computer-generated interactive web-response system and stratified by boosted protease inhibitor use at baseline. Patients were randomly assigned (2: 1) to switch to the open-label study regimen or continue the control regimen. The study regimen consisted of a fixed-dose tablet containing darunavir 800 mg, cobicistat 150 mg, emtricitabine 200 mg, and tenofovir alafenamide 10 mg, which was taken once per day for 48 weeks. The primary outcome was the proportion of participants with virological rebound (confirmed viral load >= 50 copies per mL or premature discontinuations, with last viral load >= 50 copies per mL) cumulative through week 48; we tested non-inferiority (4% margin) of the study regimen versus the control regimen in the intention-to-treat population. This study is registered with ClinicalTrials.gov, number NCT02269917. Findings The study began on April 1, 2015, and the cutoff date for the week 48 primary analysis was Feb 24, 2017. Of 1141 patients (763 in the study group and 378 in the control group), 664 (58%) had previously received five or more antiretrovirals, including screening antiretrovirals, and 169 (15%) had previous virological failure on a non-darunavir regimen. The study regimen was non-inferior to the control for virological rebound cumulative through week 48 (19 [2. 5%] of 763 patients in the study group vs eight (2 .1%) of 378 patients in the control group; difference 0.4%, 95% CI - 1.5 to 2 . 2; p< 0.0001). No resistance to any study drug was observed. Numbers of discontinuations related to adverse events (11 [1%] of 763 patients in the study group vs four [1%] of 378 patients in the control group) and grade 3-4 adverse events (52 [7%] patients vs 31 [8%] patients) were similar between the two groups. There was a small non-clinically relevant but statistically significant (0 . 2 [SD 1.1] vs 0.1 [1.1], p=0.010) difference between the two groups in change from baseline in total cholesterol to HDL-cholesterol ratio. Only one serious adverse event (pancreatitis in the study group) was deemed as possibly related to the study regimen. Interpretation Our findings show the safety and efficacy of single-tablet darunavir, cobicistat, emtricitabine, and tenofovir alafenamide as a potential switch option for the treatment of HIV-1 infection in adults with viral suppression.

Objective: To report the 10-year follow-up of the MAINTAIN Nephritis Trial comparing azathioprine (AZA) and mycophenolate mofetil (MMF) as maintenance therapy of proliferative lupus nephritis, and to test different definitions of early response as predictors of long-term renal outcome. Methods: In 2014, data on survival, kidney function, 24 h proteinuria, renal flares and other outcomes were collected for the 105 patients randomised between 2002 and 2006, except in 13 lost to follow-up. Results: Death (2 and 3 in the AZA and MMF groups, respectively) and end-stage renal disease (1 and 3, respectively) were rare events. Time to renal flare (22 and 19 flares in AZA and MMF groups, respectively) did not differ between AZA and MMF patients. Patients with good long-term renal outcome had a much more stringent early decrease of 24 h proteinuria compared with patients with poor outcome. The positive predictive value of a 24 h proteinuria

BACKGROUND: In the MAINTAIN Nephritis Trial, azathioprine (AZA) and mycophenolate mofetil (MMF) were compared as maintenance immunosuppressive treatment of proliferative lupus nephritis (LN) after a short-course of intravenous cyclophosphamide. Here, we compare the pathological findings on repeat kidney biopsies between the two groups. METHODS: Per protocol, repeat renal biopsies were obtained in 30 patients (16 AZA and 14 MMF) at 2 years (±6 months). Baseline and follow-up biopsies were graded according to the International Society of Nephrology/Renal Pathological Society (ISN/RPS) classification. The activity and chronicity indices (AI, CI) were calculated using two different semiquantitative scoring systems (Morel-Maroger and National Institutes of Health). Statistics were performed by non-parametric tests. RESULTS: The clinical characteristics of the 30 re-biopsied patients only marginally differ from the entire MAINTAIN cohort (105 patients). Clinical baseline and follow-up characteristics of AZA- and MMF-treated re-biopsied patients did not differ. Time (SD) to repeat renal biopsy was 25.0 (2.0) and 26.5 (3.3) months in AZA and MMF patients, respectively. More patients had normal renal biopsies or Classes I/II/V LN at follow-up compared to baseline and conversely, less patients had Class IV LN at follow-up. In both groups, the AI statistically decreased at follow-up compared to baseline, while the CI slightly, but significantly, increased. No differences could be detected between the groups. CONCLUSION: Centralized pathological analyses, including ISN/RPS classification and comparisons of AI/CI, failed to find differences between MMF and AZA at 2 years, a result well in line with the absence of difference in long-term clinical outcome reported elsewhere.

Background: Although an early decrease in proteinuria has been correlated with good long-term renal outcome in lupus nephritis (LN), studies aimed at defining a cut-off proteinuria value are missing, except a recent analysis performed on patients randomised in the Euro-Lupus Nephritis Trial, demonstrating that a target value of 0.8 g/day at month 12 optimised sensitivity and specificity for the prediction of good renal outcome. The objective of the current work is to validate this target in another LN study, namely the MAINTAIN Nephritis Trial (MNT). Methods: Long-term (at least 7 years) renal function data were available for 90 patients randomised in the MNT. Receiver operating characteristic curves were built to test the performance of proteinuria measured within the 1st year as short-term predictor of long-term renal outcome. We calculated the positive and negative predictive values (PPV, NPV). Results: After 12 months of treatment, achievement of a proteinuria

From the dried flower heads of Matricaria recutita L., essential oil was isolated by hydrodistillation, and in the obtained blue oil, α-bisabolol oxide A (21.5%), α-bisabolol oxide B (25.5%) and (Z)-spiroether (cis-en-yn-spiroether) (10.3%) were identified as the main compounds, by gas chromatography (GC) and GC-mass spectrometry analyses. The antihyperalgesic effects of this oil were examined in a rat model of inflammation induced by carrageenan, through a modified 'paw-pressure' test. Antiedematous effects were examined in a rat model of inflammation induced by carrageenan, dextran and histamine, through plethysmometry. Matricaria oil (25, 50 and 100 mg/kg, p.o.) exhibited a significant dose-dependent reduction of hyperalgesia and edema induced by carrageenan in both prophylactic and therapeutic treatment schemes. It was more efficacious in the prophylactic treatment scheme, and the corresponding median effective dose (ED50) ± standard error of the mean (SEM) values were 49.8 ± 6.0 and 42.4 ± 0.2 mg/kg for antihyperalgesic and antiedematous effects, respectively. Prophylactic treatments with matricaria oil (25, 50 and 100 mg/kg, p.o.) caused a significant dose-dependent antiedematous effect in dextran-induced edema with lower efficacy than in the carrageenan model. In a dose of 100 mg/kg, p.o., matricaria oil caused a slight reduction of histamine-induced edema. These results suggest that bisabolol-oxide-rich matricaria oil may be effective against pain and edema present in various inflammatory conditions, which supports matricaria traditional uses.

Université Catholique de Louvain, Brussels, Belgium. houssiau@ruma.ucl.ac.be Abstract OBJECTIVE: In the Euro-Lupus Nephritis Trial (ELNT), 90 patients with lupus nephritis were randomly assigned to a high-dose intravenous cyclophosphamide (IV CYC) regimen (6 monthly pulses and 2 quarterly pulses with escalating doses) or a low-dose IV CYC regimen (6 pulses of 500 mg given at intervals of 2 weeks), each of which was followed by azathioprine (AZA). After a median followup of 41 months, a difference in efficacy between the 2 regimens was not observed. The present analysis was undertaken to extend the followup and to identify prognostic factors. METHODS: Renal function was prospectively assessed quarterly in all 90 patients except 5 who were lost to followup. Survival curves were derived using the Kaplan-Meier method. RESULTS: After a median followup of 73 months, there was no significant difference in the cumulative probability of end-stage renal disease or doubling of the serum creatinine level in patients who received the low-dose IV CYC regimen versus those who received the high-dose regimen. At long-term followup, 18 patients (8 receiving low-dose and 10 receiving high-dose treatment) had developed permanent renal impairment and were classified as having poor long-term renal outcome. We demonstrated by multivariate analysis that early response to therapy at 6 months (defined as a decrease in serum creatinine level and proteinuria

Objective. Glomerulonephritis is a severe manifestation of systemic lupus erythematosus (SLE) that is usually treated with an extended course of intravenous (IV) cyclophosphamide (CYC). Given the side effects of this regimen, we evaluated the efficacy and the toxicity of a course of low-dose IV CYC prescribed as a remission-inducing treatment, followed by azathioprine (AZA) as a remission-maintaining treatment. Methods. In this multicenter, prospective clinical trial (the Euro-Lupus Nephritis Trial [ELNT]), we randomly assigned 90 SLE patients with proliferative glomerulonephritis to a high-dose IV CYC regimen (6 monthly pulses and 2 quarterly pulses; doses increased according to the white blood cell count nadir) or a low-dose IV CYC regimen (6 fortnightly pulses at a fixed dose of 500 mg), each of which was followed by AZA. Intent-to-treat analyses were performed. Results. Followup continued for a median of 41.3 months in the low-dose group and 41 months in the high-dose group. Sixteen percent of those in the low-dose group and 20% of those in the high-dose group experienced treatment failure (not statistically significant by Kaplan-Meier analysis). Levels of serum creatinine, albumin, C3, 24-hour urinary protein, and the disease activity scores significantly improved in both groups during the first year of followup. Renal remission was achieved in 71% of the low-dose group and 54% of the high-dose group (not statistically significant). Renal flares were noted in 27% of the low-dose group and 29% of the high-dose group. Although episodes of severe infection were more than twice as frequent in the high-dose group, the difference was not statistically significant. Conclusion. The data from the ELNT indicate that in European SLE patients with proliferative lupus nephritis, a remission-inducing regimen of low-dose IV CYC (cumulative dose 3 gm) followed by AZA achieves clinical results comparable to those obtained with a high-dose regimen
