Anaemia management with C.E.R.A. in routine clinical practice: OCEANE (Cohorte Mircera patients non-dialyses), a national, multicenter, longitudinal, observational prospective study, in patients with chronic kidney disease not on dialysis.

ABSTRACT: The aim of this study was to describe the management of anaemia with a continuous erythropoietin receptor activator (C.E.R.A., methoxy polyethylene glycol epoetin-β), in patients with chronic kidney disease (CKD) not on dialysis, naïve or non-naïve to treatment with erythropoiesis-stimulating agents (ESAs) at inclusion. National, multicentre, longitudinal, observational prospective study. 133 nephrologists practicing in France selected patients during their routine follow-up visits. The study was non-interventional. They were adult CKD patients not on dialysis or kidney transplant patients, naïve or not to ESA treatment: 524 patients not on dialysis (48% ESA-naïve) and 92 kidney transplant patients (24% ESA-naïve) were included and followed up every 3 months during 1 year. The two main endpoints were the percentage of patients who achieved target haemoglobin (Hb) levels as per European Medicines Agency guidelines (10-12 g/dl) around 6 months of treatment and modalities of treatment. Approximately one in two patients had an Hb level within 10-12 g/dl at baseline, and around 6 and 12 months of treatment. Ninety per cent of ESA-naïve patients achieved at least +1 g/dl increase over baseline Hb levels or had Hb within 10-12 g/dl around 6 and 12 months. The Hb level remained at approximately 11.5 g/dl during the 12 months of follow-up. Around 6 months: almost all patients were receiving a once-monthly subcutaneous dose of C.E.R.A. (patients not on dialysis: 95±54 µg; kidney transplant patients: 121±70 µg); approximately half the patients did not require a change in C.E.R.A. dose. Adverse effects related to C.E.R.A. were observed in less than 5% of patients and led to modification or discontinuation of treatment in 2%. The efficacy and safety of C.E.R.A. in CKD patients not on dialysis, with or without kidney transplantation, were confirmed in routine clinical practice.

Project description:IntroductionHyporesponsiveness to erythropoiesis-stimulating agents (ESAs) in patients with anaemia of chronic kidney disease may lead to increased ESA doses to achieve target haemoglobin levels; however, elevated doses may be associated with increased mortality. Furthermore, patients with hyporesponsiveness to ESAs have poorer clinical outcomes than those who respond well to ESAs. Incidence and clinical characteristics of patients with ESA hyporesponsiveness were explored in a real-world setting.MethodsThis was a retrospective study of electronic medical records of adults with stage 5 chronic kidney disease receiving renal replacement therapy and ESA treatment, from 1 January 2015 to 31 December 2021. The primary objective was ESA hyporesponsiveness rate/1000 days, with a hyporesponsive event defined as ESA use at an elevated dose, according to National Institute for Health and Care Excellence (NICE) criteria. Other hyporesponsiveness definitions applied were erythropoietin resistance index-defined ESA hyporesponsiveness (ERI) Kidney Disease Improving Global Outcomes (KDIGO) and a clinical practicality algorithm.ResultsIn total, 85,259 patients were included in the analysis; 59.9% were male, median (interquartile range) ESA starting dose was 733.3 (400.0, 1200.0) IU/week and follow-up duration was 2.2 (1.0, 4.2) years. Incidence of ESA hyporesponsiveness varied when applying different definitions; NICE 0.05/1000 days (5.2% of patients), ERI 0.40/1000 days (40.7%), KDIGO 0.15/1000 days (15.4%), and clinical practicality algorithm 0.48/1000 days (47.9%). ESA doses remained higher in hyporesponsive versus responsive patients, yet haemoglobin levels were similar between groups.ConclusionThe results from this study, which applied multiple hyporesponsiveness definitions to a large, geographically diverse population of patients with anaemia of CKD, showed variation in ESA hyporesponsiveness incidence rates depending on definitions used and higher ESA doses in hyporesponsive versus responsive patients. These results underscore the need for individualised clinical assessment and thorough evaluation when considering ESA dose adjustments to reach haemoglobin targets.

Project description:BackgroundThe coronavirus disease 2019 (COVID-19) pandemic is rapidly expanding across the world, with more than 100,000 new cases each day as of end-June 2020. Healthcare workers are struggling to provide the best care for COVID-19 patients. Approaches for invasive ventilation vary widely between and within countries and new insights are acquired rapidly. We aim to investigate invasive ventilation practices and outcome in COVID-19 patients in the Netherlands.MethodsPRoVENT-COVID ('study of PRactice of VENTilation in COVID-19') is an investigator-initiated national, multicenter observational study to be undertaken in intensive care units (ICUs) in The Netherlands. Consecutive COVID-19 patients aged 18 years or older, who are receiving invasive ventilation in the participating ICUs, are to be enrolled during a 10-week period, with a daily follow-up of 7 days. The primary outcome is ventilatory management (including tidal volume expressed as mL/kg predicted body weight and positive end-expiratory pressure expressed as cmH2O) during the first 3 days of ventilation. Secondary outcomes include other ventilatory variables, use of rescue therapies for refractory hypoxemia such as prone positioning and extracorporeal membrane oxygenation, use of sedatives, vasopressors and inotropes; daily cumulative fluid balances; acute kidney injury; ventilator-free days and alive at day 28 (VFD-28), duration of ICU and hospital stay, and ICU, hospital and 90-day mortality.DiscussionPRoVENT-COVID will be the largest observational study to date, with high density ventilatory data and major outcomes. There is urgent need for a better understanding of ventilation practices, and the effects of ventilator settings on outcomes in COVID-19 patients. The results of PRoVENT-COVID will be rapidly disseminated through electronic presentations, such as webinars and electronic conferences, and publications in international peer-reviewed journals. Access to source data will be made available through local, regional and national anonymized datasets on request, and after agreement of the PRoVENT-COVID steering committee.Trial registrationPRoVENT-COVID is registered at clinicaltrials.gov (identifier NCT04346342).

Project description:BackgroundAnaemia can be a pointer of underlying severe disease, including undiagnosed malignancy. Subsequent blood tests are essential to classify the anaemia into subtypes and to facilitate targeted diagnostic investigation to ensure timely diagnosis of underlying disease.ObjectiveWe aimed to describe and classify anaemia based on laboratory tests from patients with new-onset anaemia detected in general practice. An additional aim was to analyse associations between patient characteristics and unclassified anaemia (not classifiable according to an algorithm).DesignPopulation-based cross-sectional study.SettingDanish general practice.SubjectsA total of 62,731 patients (age: 40-90 years) with new-onset anaemia were identified in Danish laboratory information systems and nationwide registries, and data were obtained for 2014-2018.Main outcome measuresWe measured the proportion of patients classified into subtypes of anaemia based on blood tests requested by general practitioners within 31 days of the anaemia index date.ResultsOf the 62,731 patients with new-onset anaemia, we identified unclassified anaemia in 78.9% (95% confidence interval (CI): 77.3-80.5) of men and 65.1% (CI: 63.4-66.9) of women. The likelihood of unclassified anaemia increased with age, increasing comorbidity and decreasing severity of anaemia.ConclusionThe majority of patients with new-onset anaemia could not be classified through a simple algorithm due to missing blood tests, which highlights a potential missed opportunity for diagnosis. Standardised laboratory testing of patients with anaemia is warranted to ensure adequate follow-up and early detection of underlying severe disease.KEY POINTSAnaemia can be a sign of malignancy, and anaemia classification is an important step in the diagnosis of underlying disorders.The majority of patients with anaemia could not be classified according to a simple algorithm due to missing blood tests.Some patient characteristics were associated with a high risk of unclassified anaemia: high age, high comorbidity, and severe anaemia.Standardised laboratory testing in patients with anaemia is needed to inform targeted diagnostic investigation to ensure timely diagnosis.

Project description:BackgroundSevere secondary hyperparathyroidism (SHPT) is associated with mortality in end stage kidney disease (ESKD). Parathyroidectomy (PTX) becomes necessary when medical therapy fails, thus highlighting the interest to compare biochemical and clinical outcomes of patients receiving either medical treatment or surgery.MethodsWe aimed to compare overall survival and biochemical control of hemodialysis patients with severe hyperparathyroidism, treated by surgery or medical therapy followed-up for 36 months. Inclusion criteria were age older than 18 years, renal failure requiring dialysis treatment (hemodialysis or peritoneal dialysis) and ability to sign the consent form. A control group of 418 patients treated in the same centers, who did not undergo parathyroidectomy was selected after matching for age, sex, and dialysis vintage.ResultsFrom 82 Dialysis units in Italy, we prospectively collected data of 257 prevalent patients who underwent parathyroidectomy (age 58.2 ± 12.8 years; M/F: 44%/56%, dialysis vintage: 15.5 ± 8.4 years) and of 418 control patients who did not undergo parathyroidectomy (age 60.3 ± 14.4 years; M/F 44%/56%; dialysis vintage 11.2 ± 7.6 y). The survival rate was higher in the group that underwent parathyroidectomy (Kaplan-Meier log rank test = 0.002). Univariable analysis (HR 0.556, CI: 0.387-0.800, p = 0.002) and multivariable analysis (HR 0.671, CI:0.465-0.970, p = 0.034), identified parathyroidectomy as a protective factor of overall survival. The prevalence of patients at KDOQI targets for PTH was lower in patients who underwent parathyroidectomy compared to controls (PTX vs non-PTX: PTH < 150 pg/ml: 59% vs 21%, p = 0.001; PTH at target: 18% vs 37% p = 0.001; PTH > 300 pg/ml 23% vs 42% p = 0.001). The control group received more intensive medical treatment with higher prevalence of vitamin D (65% vs 41%, p = 0.0001), calcimimetics (34% vs 14%, p = 0.0001) and phosphate binders (77% vs 66%, p = 0.002).ConclusionsOur data suggest that parathyroidectomy is associated with survival rate at 36 months, independently of biochemical control. Lower exposure to high PTH levels could represent an advantage in the long term.

Project description:IntroductionBaricitinib is an oral Janus kinase (JAK)1/JAK2 inhibitor approved to treat rheumatoid arthritis (RA). This study aimed to investigate patients' characteristics, prescription patterns, effectiveness, and treatment persistence in patients receiving baricitinib in real-world practice in Spain.MethodsThis retrospective longitudinal cohort study conducted in five rheumatology units included adults with RA initiating baricitinib (Sep-2017-May-19) with at least a 6-month-follow-up. Demographic/clinical characteristics, prescription patterns, and changes in disease activity and pain level were collected until treatment discontinuation/end of follow-up. Treatment persistence was estimated by Kaplan-Meier methods.ResultsData from 182 patients were included (mean (SD)): 83.5% women, 62.2 (12.3) years, body mass index 26.8 (5.1), disease duration 13.2 (10.8) years and Charlson Comorbidity Index score 2.4 (2.0). All patients had received at least one conventional synthetic disease-modifying anti-rheumatic drugs (csDMARD) before starting baricitinib and 78.0% at least one biologic disease-modifying anti-rheumatic drugs (bDMARD). Furthermore, 90.1% started with baricitinib 4 mg/day; 43.4% in monotherapy. One hundred and twelve (61.5%) of patients continued baricitinib at data collection time; mean persistence was 14.1 (0.5) months. Overall treatment persistence was 79.7/64.8/59.1% at 6/12/18 months. Seventy (38.5%) patients discontinued baricitinib during follow-up due to loss of efficacy (68.6%) or adverse events (18.6%). In those patients with available scores at the different observed cut-off points, remission or low disease activity was reported in 71.6 and 76.3% of patients at 6/12 months at any index: Disease Activity Score 28 joints using erythrocyte sedimentation rate (DAS28-ESR) (73.1 and 73.5%), Simplified Disease Activity Index (SDAI) (62.4 and 75.0%), and Clinical Disease Activity Index (CDAI) (66.7 and 78.1%). Good or moderate European League Against Rheumatism (EULAR)-response was noted in 80.0 and 78.2% of patients, respectively. Improvement from baseline in pain (Visual Analog Scale) was 2.5 cm and 3.0 cm at 6/12 months, respectively.ConclusionsThis Spanish cohort of patients treated with baricitinib had a long-standing and refractory disease. Nevertheless, high persistence and improvements in disease activity and pain were found at 6 and 12 months after treatment initiation, independently of the composite disease activity measure used, reinforcing the effectiveness of baricitinib in routine clinical practice.

Project description:IntroductionWe aimed to study the characteristics of peritoneal dialysis (PD) patients with coronavirus disease-19 (COVID-19), determine the short-term mortality and other medical complications, and delineate the factors associated with COVID-19 outcome.MethodsIn this multicenter national study, we included PD patients with confirmed COVID-19 from 27 centers. The baseline demographic, clinical, laboratory, and radiological data and outcomes at the end of the first month were recorded.ResultsWe enrolled 142 COVID-19 patients (median age: 52 years). 58.2% of patients had mild disease at diagnosis. Lung involvement was detected in 60.8% of patients. Eighty-three (58.4%) patients were hospitalized, 31 (21.8%) patients were admitted to intensive care unit and 24 needed mechanical ventilation. Fifteen (10.5%) patients were switched to hemodialysis and hemodiafiltration was performed for four (2.8%) patients. Persisting pulmonary symptoms (n = 27), lower respiratory system infection (n = 12), rehospitalization for any reason (n = 24), malnutrition (n = 6), hypervolemia (n = 13), peritonitis (n = 7), ultrafiltration failure (n = 7), and in PD modality change (n = 8) were reported in survivors. Twenty-six patients (18.31%) died in the first month of diagnosis. The non-survivor group was older, comorbidities were more prevalent. Fever, dyspnea, cough, serious-vital disease at presentation, bilateral pulmonary involvement, and pleural effusion were more frequent among non-survivors. Age (OR: 1.102; 95% CI: 1.032-1.117; p: 0.004), moderate-severe clinical disease at presentation (OR: 26.825; 95% CI: 4.578-157.172; p < 0.001), and baseline CRP (OR: 1.008; 95% CI; 1,000-1.016; p: 0.040) were associated with first-month mortality in multivariate analysis.Discussion/conclusionsEarly mortality rate and medical complications are quite high in PD patients with COVID-19. Age, clinical severity of COVID-19, and baseline CRP level are the independent parameters associated with mortality.

Project description:PurposeThis postmarketing surveillance survey was conducted to investigate the utility of the CONsistency in r-FSH Starting dOses for individualized tReatmenT (CONSORT) calculator for individualizing recombinant human follicle-stimulating hormone (r-hFSH) starting doses for controlled ovarian stimulation (COS) in routine clinical practice.MethodsThis was a 3-year, open-label, observational study evaluating data from women undergoing COS for assisted reproductive technology at 31 German fertility centers. Physicians stated their recommended r-hFSH starting dose, then generated a CONSORT-recommended r-hFSH starting dose. Physicians could prescribe any r-hFSH starting dose. The primary objective was to compare the r-hFSH starting dose recommended by the physician with the CONSORT-calculated dose and that prescribed. Statistical analyses were conducted post hoc.ResultsData were collected from 2,579 patients; the mean (standard deviation [SD]) age was 30.5 (2.93) years (range: 19-40 years). The mean (SD) CONSORT-calculated r-hFSH starting dose was significantly lower than the physician-recommended dose (134.5 [38.0] IU versus 164.6 [47.1] IU; P<0.0001); the mean (SD) starting dose prescribed was 162.2 (48.4) IU. CONSORT-calculated doses were prescribed for 27.3% (number [n] =677) of patients, and non-CONSORT-calculated doses prescribed for 72.7% (n=1,800). The mean (SD) number of oocytes retrieved per patient was 10.6 (6.15) and 11.4 (6.66) in the CONSORT and non-CONSORT groups, respectively; the mean (SD) number of embryos transferred per patient was 1.98 (0.41) and 2.03 (0.45), respectively. Clinical pregnancy rates per COS cycle were 38.8% (CONSORT) and 34.8% (non-CONSORT) (P=0.142); clinical pregnancy rates per embryos transferred were 45.0% and 39.5%, respectively (P=0.049). Miscarriage occurred in 14.8% of all clinical pregnancies (Consort12.5%; non-Consort15.3%). The rate of grade 3 ovarian hyperstimulation syndrome (OHSS) was 0.3% (n=2) in the CONSORT group and 0.6% (n=11) in the non-CONSORT group. OHSS led to hospitalization in 0.81% (n=21) of cases (CONSORT group: 0.74% [n=5]; non-CONSORT group: 0.83% [n=15]).ConclusionPhysician-recommended r-hFSH starting doses were generally higher than those calculated by CONSORT; most patients were prescribed a higher starting dose than that recommended by CONSORT.
