Hypertension and Cardiovascular Outcomes in Inflammatory and Autoimmune Diseases: A Systematic Review and Meta-analysis.

PURPOSE: This review aimed to investigate the prevalence of hypertension and cardiovascular (CV) complications in various inflammatory and autoimmune diseases (IAD). RECENT FINDINGS: Despite recent improvements in the management of IAD, patients with IAD still have an increased CV mortality and CV complications, mostly related to CV risk factors such as hypertension and inflammation. We systematically searched MEDLINE and EMBASE libraries for controlled studies involving hypertension and CV complications in systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), psoriasis including psoriatic arthritis (PsA), Sjogren's syndrome (SS), or antineutrophil cytoplasmic antibody-associated vasculitis (AAV) between January 2000 and March 2022. We extracted data on the prevalence of hypertension and CV complications. Then, random-effects meta-analyses and exploratory multivariate meta-regression were performed to explore factors related to the prevalence of hypertension. Of 2726 studies screened, 122 were selected for the meta-analysis. The prevalence of hypertension was higher among patients with IAD than controls, with an overall unadjusted odds ratio (OR) [95% confidence interval] of 1.67 [1.58-1.76] and an adjusted OR of 1.36 [1.24-1.50]. All diseases were found to be associated with increased risk of hypertension: SLE, adjusted OR 3.40 [1.93-6.00]; psoriasis, OR 1.32 [1.16-1.51]; PsA, OR 1.49 [1.15-1.94]; RA, OR 1.28 [1.04-1.58]; SS, OR 2.02 [1.19-3.44]. Age and female sex were significantly associated with hypertension in patients with IAD. The risk of CV complications was increased: ischemic heart disease, adjusted OR 1.38 [1.21-1.57]; cerebrovascular disease, OR 1.37 [1.03-1.81]; heart failure, OR 1.28 [1.05-1.55]; atherosclerotic plaques presence, OR 2.46 [1.84-3.29]. The prevalence of hypertension and CV complications is higher among patients with IAD. Screening and management of hypertension appears to be of paramount importance in these patients.

Management of patients with hypertension and chronic kidney disease referred to Hypertension Excellence Centres among 27 countries. On behalf of the European Society of Hypertension Working Group on Hypertension and the Kidney.

Objective Real-life management of patients with hypertension and chronic kidney disease (CKD) among European Society of Hypertension Excellence Centres (ESH-ECs) is unclear : we aimed to investigate it. Methods A survey was conducted in 2023. The questionnaire contained 64 questions asking ESH-ECs representatives to estimate how patients with CKD are managed. Results Overall, 88 ESH-ECS representatives from 27 countries participated. According to the responders, renin-angiotensin system (RAS) blockers, calcium-channel blockers and thiazides were often added when these medications were lacking in CKD patients, but physicians were more prone to initiate RAS blockers (90% [interquartile range: 70-95%]) than MRA (20% [10-30%]), SGLT2i (30% [20-50%]) or (GLP1-RA (10% [5-15%]). Despite treatment optimisation, 30% of responders indicated that hypertension remained uncontrolled (30% (15-40%) vs 18% [10%-25%]) in CKD and CKD patients, respectively). Hyperkalemia was the most frequent barrier to initiate RAS blockers, and dosage reduction was considered in 45% of responders when kalaemia was 5.5-5.9 mmol/L. Conclusions RAS blockers are initiated in most ESH-ECS in CKD patients, but MRA and SGLT2i initiations are less frequent. Hyperkalemia was the main barrier for initiation or adequate dosing of RAS blockade, and RAS blockers' dosage reduction was the usual management.

What is the context? Hypertension is a strong independent risk factor for development of chronic kidney disease (CKD) and progression of CKD to ESKD. Improved adherence to the guidelines in the treatment of CKD is believed to provide further reduction of cardiorenal events. European Society of Hypertension Excellence Centres (ESH-ECs) have been developed in Europe to provide excellency regarding management of patients with hypertension and implement guidelines. Numerous deficits regarding general practitioner CKD screening, use of nephroprotective drugs and referral to nephrologists prior to referral to ESH-ECs have been reported. In contrast, real-life management of these patients among ESH-ECs is unknown. Before implementation of strategies to improve guideline adherence in Europe, we aimed to investigate how patients with CKD are managed among the ESH-ECs.What is the study about? In this study, a survey was conducted in 2023 by the ESH to assess management of CKD patients referred to ESH-ECs. The questionnaire contained 64 questions asking ESH-ECs representatives to estimate how patients with CKD are managed among their centres.What are the results? RAAS blockers are initiated in 90% of ESH-ECs in CKD patients, but the initiation of MRA and SGLT2i is less frequently done. Hyperkalemia is the main barrier for initiation or adequate dosing of RAAS blockade, and its most reported management was RAAS blockers dosage reduction. These findings will be crucial to implement strategies in order to improve management of patients with CKD and guideline adherence among ESH-ECs.

Persistence of neutrophil extracellular traps and anticardiolipin auto-antibodies in post-acute phase COVID-19 patients.

In the early phase of the pandemic, we were among the first to postulate that neutrophil extracellular traps (NETs) play a key role in COVID-19 pathogenesis. This exploratory prospective study based on 279 individuals showed that plasma levels of neutrophil elastase, myeloperoxidase and circulating DNA of nuclear and mitochondrial origins in nonsevere (NS), severe (S) and postacute phase (PAP) COVID-19 patients were statistically different as compared to the levels in healthy individuals, and revealed the high diagnostic power of these NETs markers in respect to the disease severity. The diagnostic power of NE, MPO, and cir-nDNA as determined by the Area Under Receiver Operating Curves (AUROC) was 0.95, 097, and 0.64; 0.99, 1.0, and 0.82; and 0.94, 1.0, and 0.93, in NS, S, and PAP patient subgroups, respectively. In addition, a significant fraction of NS, S as well as of PAP patients exhibited aCL IgM/IgG and anti-B2GP IgM/IgG positivity. We first demonstrate persistence of these NETs markers in PAP patients and consequently of sustained innate immune response imbalance, and a prolonged low-level pro-thrombotic potential activity highlighting the need to monitor these markers in all COVID-19 PAP individuals, to investigate postacute COVID-19 pathogenesis following intensive care, and to better identify which medical resources will ensure complete patient recovery.

In-depth characterization of pulmonary arterial hypertension in mixed connective tissue disease: a French national multicentre study.

OBJECTIVE: Pulmonary arterial hypertension (PAH) is a leading cause of death in MCTD. We aimed to describe PAH in well-characterized MCTD patients. METHODS: MCTD patients enrolled in the French Pulmonary Hypertension Registry with a PAH diagnosis confirmed by right heart catheterization were included in the study and compared with matched controls: MCTD patients without PAH, SLE patients with PAH and SSc patients with PAH. Survival rates were estimated by the Kaplan-Meier method and risk factors for PAH in MCTD patients and risk factors for mortality in MCTD-PAH were sought using multivariate analyses. RESULTS: Thirty-six patients with MCTD-PAH were included in the study. Comparison with MCTD patients without PAH and multivariate analysis revealed that pericarditis, polyarthritis, thrombocytopenia, interstitial lung disease (ILD) and anti-Sm antibodies were independent predictive factors of PAH/PH in MCTD. Estimated survival rates at 1, 5 and 10 years following PAH diagnosis were 83%, 67% and 56%, respectively. MCTD-PAH presentation and survival did not differ from SLE-PAH and SSc-PAH. Multivariate analysis revealed that tobacco exposure was an independent factor predictive of mortality in MCTD-PAH. CONCLUSION: PAH is a rare and severe complication of MCTD associated with a 56% 10-year survival. We identified ILD, pericarditis, thrombocytopenia and anti-Sm antibodies as risk factors for PAH in MCTD and tobacco exposure as a predictor of mortality in MCTD-PAH.

Association between Elevated Plasma Vitamin B12 and Short-Term Mortality in Elderly Patients Hospitalized in an Internal Medicine Unit.

Background: The prognostic value of vitamin B12 blood levels remains controversial. An association between elevated vitamin B12 and mortality has been reported, particularly among elderly patients with cancers and liver or blood diseases. The present study explored the relationship between mortality and elevated vitamin B12 levels in a population of unscheduled inpatients in an internal medicine unit. Methods: This retrospective observational analysis was conducted between August 2014 and December 2018. We compared 165 patients with elevated plasma vitamin B12 levels (>600 pmol/l) with a random sample of 165 patients with normal B12 levels who were hospitalized during the same period. Demographic, clinical, and biological characteristics were assessed during hospitalization. The primary endpoint was all-cause death at 1 year. Results: Patients with elevated B12 were younger, with a lower body mass index and lower plasma albumin than those with normal B12 (75 ± 16 years vs 79 ± 13 years, p = 0.047; 23 ± 5 vs 26 ± 7 kg/m2, p < 0.001; and 33 ± 5 vs 35 ± 5 g/l, p < 0.001, respectively). The prevalence of auto-immune disease and referral from an intensive care unit was higher among patients with elevated B12 (11% vs 5%, p = 0.043 and 36% vs 10%, p < 0.001, respectively). After 1 year of follow-up, 64 (39%) patients with elevated B12 had died compared to 43 (26%) patients with normal B12 (p = 0.018). Multivariate analysis using the Cox proportional hazards regression model adjusted for age, gender, body mass index, intensive care unit hospitalization, albumin level, and the presence of solid cancer or autoimmune disease revealed elevated B12 to be associated with a significant risk of death in the first year of follow-up (hazard ratio: 1.71 [1.08-2.7], p = 0.022). Conclusion: Elevated B12 is an early warning indicator of increased short-term mortality, such as independently of age, cancer, or comorbidities, in patients hospitalized in an internal medicine department.

Pulmonary hypertension reported with immune checkpoint inhibitors: a pharmacovigilance study.

Immune checkpoint inhibitors (ICI) restore immune response against cancer cells that can lead to immune-related adverse effects. While cardiovascular immune-related adverse effects are known to be associated with checkpoint inhibitors, recent case reports have raised concerns about the potential association with pulmonary hypertension (PH). By using the global pharmacovigilance database VigiBase, we investigated the onset of PH associated with ICI and propose a comprehensive description of the 42 cases of PH reported with ICI recorded in this database. Through this study and review of the cases published in the literature, we discuss the possible link between PH and ICI in the context of cancer in order to better understand this rare but potentially fatal event.

Analytical evaluation and bioclinical validation of new aldosterone and renin immunoassays.

OBJECTIVES: Aldosterone and renin determinations play an important role in the etiological diagnosis of secondary hypertension. The analytical performances of new aldosterone and renin immunoassays on the Lumipulse G600II® system (Fujierbio) were investigated and compared with those of the iSYS® system (IDS) on patients concerned by medical investigations in a context of suspected or proven Primary aldosteronism. METHODS: By using the Lumipulse® G Aldosterone and Renin assays we performed imprecision study, linearity and method comparison (n=107). Accuracy of this new renin assay was tested using the International Standard (WHO IS 68/356). We also assessed the equivalence of the different samples types (n=29). RESULTS: The imprecision evaluation showed all CVs <3% and <6% for Lumipulse® G Aldosterone and Renin assays respectively. The linearity was excellent over the clinical range and the comparison with the iSYS® assays (n=79) showed a strong correlation (R2=1) despite a slight tendency to underestimation (bias of -17.53 pg/mL or 48.56 pmol/L for aldosterone and -15.395 pg/mL for renin). Moreover, the contingency studies based on diagnostic criteria showed that Lumipulse® G results lead to the same clinical diagnosis that iSYS® results. A clear correlation was obtained between EDTA and heparin plasma as well as with the serum for all range of measures. CONCLUSIONS: The Lumipulse® G Aldosterone and Renin assays present performances compatible with a routine use in medical laboratories. The precise quantification in the low range can be of interest in some clinical contexts especially standing/laying tests. However, the standardisation against the WHO International Standard Renin would be advisable.

Microvascular Disease in Chronic Thromboembolic Pulmonary Hypertension: Hemodynamic Phenotyping and Histomorphometric Assessment.

BACKGROUND: Pulmonary endarterectomy (PEA) is the gold standard treatment for patients with operable chronic thromboembolic pulmonary hypertension. However, persistent pulmonary hypertension (PH) after PEA remains a major determinant of poor prognosis. A concomitant small-vessel arteriopathy in addition to major pulmonary artery obstruction has been suggested to play an important role in the development of persistent PH and survival after PEA. One of the greatest unmet needs in the current preoperative evaluation is to assess the presence and severity of small-vessel arteriopathy. Using the pulmonary artery occlusion technique, we sought to assess the presence and degree of small-vessel disease in patients with chronic thromboembolic pulmonary hypertension undergoing PEA to predict postoperative outcome before surgery. METHODS: Based on pulmonary artery occlusion waveforms yielding an estimate of the effective capillary pressure, we partitioned pulmonary vascular resistance in larger arterial (upstream resistance [Rup]) and small arterial plus venous components (downstream resistance) in 90 patients before PEA. For validation, lung wedge biopsies were taken from nonobstructed and obstructed lung territories during PEA in 49 cases. Biopsy sites were chosen according to the pulmonary angiogram still frames that were mounted in the operating room. All vessels per specimen were measured in each patient. Percent media (%MT; arteries) and intima thickness (%IT; arteries, veins, and indeterminate vessels) were calculated relative to external vessel diameter. RESULTS: Decreased Rup was an independent predictor of persistent PH (odds ratio per 10%, 0.40 [95% CI, 0.23-0.69]; P=0.001) and survival (hazard ratio per 10%, 0.03 [95% CI, 0.00-0.33]; p=0.004). Arterial %MT and %IT of nonobstructed lung territories and venous %IT of obstructed lung territories were significantly increased in patients with persistent PH and nonsurvivors. Rup correlated inversely with %MT (r=-0.72, P<0.001) and %IT (r=-0.62, P<0.001) of arteries from nonobstructed lung territories and with %IT (r=-0.44, P=0.024) of veins from obstructed lung territories. Receiver operating characteristic analysis disclosed that Rup <66% predicted persistent PH after PEA, whereas Rup <60% identified patients with poor prognosis after PEA. CONCLUSIONS: Pulmonary artery occlusion waveform analysis with estimation of Rup seems to be a valuable technique for assessing the degree of small-vessel disease and postoperative outcome after PEA in chronic thromboembolic pulmonary hypertension.

Development and validation of a score to assess risk of medication errors detected during medication reconciliation process at admission in internal medicine unit: SCOREM study.

BACKGROUND: Medication errors (ME) can be reduced through preventive strategies such as medication reconciliation. Such strategies are often limited by human resources and need targeting high risk patients. AIMS: To develop a score to identify patients at risk of ME detected during medication reconciliation in a specific population from internal medicine unit. METHODS: Prospective observational study conducted in an internal medicine unit of a French University Hospital from 2012 to 2016. Adult hospitalised patients were eligible for inclusion. Medication reconciliation was conducted by a pharmacist and consisted in comparing medication history with admission prescription to identify MEs. Risk factors of MEs were analysed using multivariate stepwise logistic regression model. A risk score was constructed using the split-sample approach. The split was done at random (using a fixed seed) to define a development data set (N = 1256) and a validation sample (N = 628). A regression coefficient-base scoring system was used adopting the beta-Sullivan approach (Sullivan's scoring). RESULTS: Pharmacists detected 740 MEs in 368/1884 (19.5%) patients related to medication reconciliation. Female gender, number of treatments >7, admission from emergency department and during night or weekend were significantly associated with a higher risk of MEs. Risk score was constructed by attributing 1 or 2 points to these variables. Patients with a score ≥3 (OR [95% CI] 3.10 [1.15-8.37]) out of 5 (OR [95% CI] 8.11 [2.89-22.78]) were considered at high risk of MEs. CONCLUSIONS: Risk factors identified in our study may help prioritising patients admitted in internal medicine units who may benefit the most from medication reconciliation (ClinicalTrials.gov number NCT03422484).

Abnormal liver tests in patients hospitalized with Coronavirus disease 2019: Should we worry?

While several studies from China have reported COVID-19-related liver injury, there are currently no data on liver dysfunction in hospitalized COVID-19 patients in Europe. The aim of this study was to describe the prevalence and predictive value of abnormal liver function in patients hospitalized with COVID-19. This was a retrospective cohort study of confirmed COVID-19 patients hospitalized in two referral hospitals in France. Clinical, biological and radiological data were collected and analysed. In all, 234 patients confirmed to have COVID-19 by RT-PCR were included. Liver function was abnormal in 66.6% of patients on admission. In multivariate logistic regression, abnormal liver test on admission were associated with in-hospital aggravation (OR = 4.1, 95% CI 1.5-10.8; P = .004) and mortality (OR 3.3; 95% CI = 1.04-10.5; P = .04). This study of liver tests in a European COVID-19 population confirms a high prevalence of abnormal liver tests on admission that are predictive of severe disease course and higher in-hospital mortality.

In-depth haemodynamic phenotyping of pulmonary hypertension due to left heart disease.

The commonest cause of pulmonary hypertension (PH) is left heart disease (LHD). The current classification system for definitions of PH-LHD is under review. We therefore performed prospective in-depth invasive haemodynamic phenotyping in order to assess the site of increased pulmonary vascular resistance (PVR) in PH-LHD subsets.Based on pulmonary artery occlusion waveforms yielding an estimate of the effective capillary pressure, we partitioned PVR in larger arterial (Rup, upstream resistance) and small arterial plus venous components (Rds, downstream resistance). In the case of small vessel disease, Rup decreases and Rds increases. Inhaled nitric oxide (NO) testing was used to assess acute vasoreactivity.Right ventricular afterload (PVR, pulmonary arterial compliance and effective arterial elastance) was significantly higher in combined post- and pre-capillary PH (Cpc-PH, n=35) than in isolated post-capillary PH (Ipc-PH, n=20). Right ventricular afterload decreased during inhalation of NO in Cpc-PH and idiopathic pulmonary arterial hypertension (n=31), but remained unchanged in Ipc-PH. Rup was similar in Cpc-PH (66.8±10.8%) and idiopathic pulmonary arterial hypertension (65.0±12.2%; p=0.530) suggesting small vessel disease, but significantly higher in Ipc-PH (96.5±4.5%; p<0.001) suggesting upstream transmission of elevated left atrial pressure.Right ventricular afterload is driven by elevated left atrial pressure in Ipc-PH and is further increased by elevated small vessel resistance in Cpc-PH. Cpc-PH is responsive to inhaled NO. Our data support current definitions of PH-LHD subsets.

sST2 as a New Biomarker of Chronic Kidney Disease-Induced Cardiac Remodeling: Impact on Risk Prediction.

Heart failure is the most frequent cardiac complication of chronic kidney disease (CKD). Biomarkers help identify high-risk patients. Natriuretic peptides (BNP and NT-proBNP) are largely used for monitoring patients with cardiac failure but are highly dependent on glomerular filtration rate (GFR). Soluble suppression of tumorigenicity 2 (sST2) biomarker is well identified in risk stratification of cardiovascular (CV) events in heart failure. Furthermore, sST2 is included in a bioclinical score to stratify mortality risk. The aims of this study were to evaluate (i) the interest of circulating sST2 level in heart dysfunction and (ii) the bioclinical score (Barcelona Bio-Heart Failure risk calculator) to predict the risk of composite outcome (major adverse coronary events) and mortality in the CKD population. A retrospective study was carried out on 218 CKD patients enrolled from 2004 to 2015 at Montpellier University Hospital. sST2 was measured by ELISA (Presage ST2® kit). GFR was estimated by the CKD-EPI equation (eGFR). Indices of cardiac parameters were performed by cardiac echography. No patient had reduced ejection fraction. 112 patients had left ventricular hypertrophy, and 184 presented cardiac dysfunction, with structural, functional abnormalities or both. sST2 was independent of age and eGFR (ρ = 0.05, p = 0.44, and ρ = -0.07, p = 0.3, respectively). Regarding echocardiogram data, sST2 was correlated with left ventricular mass index (ρ = 0.16, p = 0.02), left atrial diameter (ρ = 0.14, p = 0.04), and volume index (ρ = 0.13, p = 0.05). sST2 alone did not change risk prediction of death and/or CV events compared to natriuretic peptides. Included in the Barcelona Bio-Heart Failure (BCN Bio-HF) score, sST2 added value and better stratified the risk of CV events and/or death in CKD patients (p < 0.0001). To conclude, sST2 was associated with cardiac remodeling independently of eGFR, unlike other cardiac biomarkers. Added to the BCN Bio-HF score, the risk stratification of death and/or CV events in nondialyzed CKD patients was highly improved.

Noninvasive evaluation of left ventricular elastance according to pressure-volume curves modeling in arterial hypertension.

End-systolic left ventricular (LV) elastance (Ees) has been previously calculated and validated invasively using LV pressure-volume (P-V) loops. Noninvasive methods have been proposed, but clinical application remains complex. The aims of the present study were to 1) estimate Ees according to modeling of the LV P-V curve during ejection ("ejection P-V curve" method) and validate our method with existing published LV P-V loop data and 2) test the clinical applicability of noninvasively detecting a difference in Ees between normotensive and hypertensive subjects. On the basis of the ejection P-V curve and a linear relationship between elastance and time during ejection, we used a nonlinear least-squares method to fit the pressure waveform. We then computed the slope and intercept of time-varying elastance as well as the volume intercept (V0). As a validation, 22 P-V loops obtained from previous invasive studies were digitized and analyzed using the ejection P-V curve method. To test clinical applicability, ejection P-V curves were obtained from 33 hypertensive subjects and 32 normotensive subjects with carotid tonometry and real-time three-dimensional echocardiography during the same procedure. A good univariate relationship (r2 = 0.92, P < 0.005) and good limits of agreement were found between the invasive calculation of Ees and our new proposed ejection P-V curve method. In hypertensive patients, an increase in arterial elastance (Ea) was compensated by a parallel increase in Ees without change in Ea/Ees In addition, the clinical reproducibility of our method was similar to that of another noninvasive method. In conclusion, Ees and V0 can be estimated noninvasively from modeling of the P-V curve during ejection. This approach was found to be reproducible and sensitive enough to detect an expected increase in LV contractility in hypertensive patients. Because of its noninvasive nature, this methodology may have clinical implications in various disease states.NEW & NOTEWORTHY The use of real-time three-dimensional echocardiography-derived left ventricular volumes in conjunction with carotid tonometry was found to be reproducible and sensitive enough to detect expected differences in left ventricular elastance in arterial hypertension. Because of its noninvasive nature, this methodology may have clinical implications in various disease states.

Retinal vascular caliber associated with cardiac and renal target organ damage in never-treated hypertensive patients.

OBJECTIVE: The aim of this study was to assess the relationship between retinal vascular caliber and target organ damage in HT patients. METHODS: Data were collected on cardiac, renal, vascular, and retinal variables in 88 consecutive never-treated HT subjects. Retinal vascular calibers were measured from fundus photographs by using a semi-automated computer-assisted program and summarized as CRAE and CRVE. RESULTS: Mean CRAE and CRVE were significantly lower in patients with left ventricular hypertrophy (left ventricular mass ≥110 g/m² for women, 125 g/m² for men) than in those with normal left ventricular (CRAE: 129.4±3.7 vs 138.2±2.3 µm; P=.04; CRVE: 195.6±4.4 vs 209.8±2.7 µm; P=.008). CRAE and CRVE were negatively correlated with urinary albumin excretion (ß±SE=-15.4±3.2, P<.0001 and ß±SE=-11.9±4.4, P=.001, respectively) but were not correlated with estimated glomerular filtration rate (P=.21 and P=.75, respectively), carotid-to-femoral pulse wave velocity (P=.24 and P=.14), or carotid augmentation index (P=.43 and P=.16). CONCLUSION: In never-treated HT patients, reduced CRAE and CRVE were associated with cardiac and renal preclinical damage, ie, left ventricular hypertrophy and albuminuria, but not estimated glomerular filtration rate or vascular stiffness.

Arterial stiffness: an independent determinant of adaptive glomerular hyperfiltration after kidney donation.

After kidney donation, the remaining kidney tends to hyperfiltrate, thus limiting the initial loss of renal function. The potential determinants of this adaptive glomerular hyperfiltration (GHF) and specifically the influence of arterial function are poorly known. In 45 normotensive healthy kidney donors [51 ± 10 yr (mean ± SD), 39 females], glomerular filtration rate (GFR) was measured as the clearance of continuously infused (99m)Tc-DTPA and timed urine collections at baseline, i.e., before donation, and 1 yr after donation. GHF was computed as postdonation GFR minus half of baseline GFR. Arterial function was assessed as baseline carotid-femoral pulse wave velocity (PWV) and carotid augmentation index (AIx). After kidney donation, no significant change in blood pressure (BP) was observed, but two subjects developed hypertension. GFR decreased from 107 ± 19 to 73 ± 15 ml·min(-1)·1.73 m(-2), and mean GHF was 20 ± 10 ml·min(-1)·1.73 m(-2). In univariate analysis, GHF was inversely correlated to age (r(2) = 0.24, P = 0.01), baseline PWV (r(2) = 0.23, P = 0.001), and Aix (r(2) = 0.11, P = 0.031). Nevertheless, GHF was not correlated to baseline peripheral or central BP. In multivariate analysis, baseline PWV, but not AIx, remained inversely correlated to GHF, independently of age, baseline mean BP, and GFR (model r(2) = 0.34, P < 0.001). In healthy subjects selected for renal donation, increased arterial stiffness is associated with decreased postdonation compensatory hyperfiltration.

Screening and management of hypertensive patients with chronic kidney disease referred to Hypertension Excellence Centres among 27 countries. A pilot survey based on questionnaire.

OBJECTIVE: Real-life management of hypertensive patients with chronic kidney disease (CKD) is unclear. METHODS: A survey was conducted in 2023 by the European Society of Hypertension (ESH) to assess management of CKD patients referred to ESH-Hypertension Excellence Centres (ESH-ECs) at first referral visit. The questionnaire contained 64 questions with which ESH-ECs representatives were asked to estimate preexisting CKD management quality. RESULTS: Overall, 88 ESH-ECs from 27 countries participated (fully completed surveys: 66/88 [75.0%]). ESH-ECs reported that 28% (median, interquartile range: 15-50%) had preexisting CKD, with 10% of them (5-30%) previously referred to a nephrologist, while 30% (15-40%) had resistant hypertension. The reported rate of previous recent (<6 months) estimated glomerular filtration rate (eGFR) and urine albumin-creatinine ratio (UACR) testing were 80% (50-95%) and 30% (15-50%), respectively. The reported use of renin-angiotensin system blockers was 80% (70-90%). When a nephrologist was part of the ESH-EC teams the reported rates SGLT2 inhibitors (27.5% [20-40%] vs. 15% [10-25], P  = 0.003), GLP1-RA (10% [10-20%] vs. 5% [5-10%], P  = 0.003) and mineralocorticoid receptor antagonists (20% [10-30%] vs. 15% [10-20%], P  = 0.05) use were greater as compared to ESH-ECs without nephrologist participation. The rate of reported resistant hypertension, recent eGFR and UACR results and management of CKD patients prior to referral varied widely across countries. CONCLUSIONS: Our estimation indicates deficits regarding CKD screening, use of nephroprotective drugs and referral to nephrologists before referral to ESH-ECs but results varied widely across countries. This information can be used to build specific programs to improve care in hypertensives with CKD.

Etanercept normalises left ventricular mass in patients with rheumatoid arthritis.

BACKGROUND: Cardiovascular mortality is increased in patients with rheumatoid arthritis (RA). RA is associated with an increased left ventricular mass index (LVMI), a strong marker of cardiovascular mortality, and vessel abnormalities. Experimental studies have suggested that tumour necrosis factor α (TNFα) may induce LV hypertrophy. OBJECTIVE: To study the effect of medium-term (3- and 6-months) treatment with the TNFα inhibitor etanercept (ETN) and synthetic disease-modifying antirheumatic drugs (sDMARDs) on LV morphological features and arterial stiffness in patients with RA. METHODS: Consecutive female patients with active RA requiring treatment with ETN (n=28) or sDMARDs (n=20) were included. Clinical and biological monitoring, echocardiography and pulse wave velocity (PWV) assessment were performed at inclusion and at 3 and 6 months after the start of treatment. Paired t tests and multivariate linear regression analysis were used. RESULTS: Mean LVMI tended to be higher at baseline in the ETN group than in the sDMARD group (96.5±19.8 vs 84.3±26.8 g/m2; p=0.11 for the ETN and sDMARD groups, respectively). In patients with ETN treatment, mean LVMI was significantly decreased at 3 and 6 months (-6.3±7.6 and -14.2±9.3 g/m2; p<0.001), with no change from baseline for patients with sDMARD treatment (-2.2±10.9 and -2.7±10.2 g/m2, respectively). Blood pressure (BP) and aortic PWV were not changed by either treatment. CONCLUSIONS: ETN induced a significant decrease in LVMI with medium-term treatment with no change in BP or PWV. TNFα may be an important factor of LV hypertrophy, which may explain the benefit of TNF inhibitors on cardiovascular morbidity and mortality in RA. These results need to be confirmed by larger studies and with other TNF inhibitors.

Effect of early stage kidney disease on cardiac mass: comparison to post-donation renal function.

BACKGROUND/AIM: In chronic renal failure the increase in cardiovascular risk is in part related to the high prevalence of left ventricular hypertrophy. The aim of the present monocentric retrospective study was to evaluate the influence of the presence of parenchymal kidney disease on left ventricular geometry in normotensive (arterial pressure <140/90 mm Hg) patients (KD+, n = 50, mean age 39 ± 19 years) with mild to moderate renal failure (stage 2-3 chronic kidney disease). METHODS: Left ventricular geometry was estimated by echocardiography and compared to a group of healthy subjects with similarly reduced renal function as a consequence of renal donation (KD-, n = 63, mean age 52 ± 12 years). RESULTS: Subjects with and without kidney disease had similar blood pressure, body mass index and isotopic glomerular filtration rate. Left ventricular mass (LVM) indexed to body surface area was greater in KD+ as compared to KD- subjects and the difference was more pronounced in women than in men. The increase in LVM in KD+ patients was associated with lower albuminemia and hematocrit, and a higher plasma renin activity and aldosterone as compared to KD- subjects. In multivariate analysis, kidney disease emerged as an important determinant of LVM index independently of age, gender and blood pressure. CONCLUSION: This observation suggests that the presence of kidney disease has an independent amplifying effect on LVM which could be related to volume overload and/or prohypertrophic factors such as aldosterone.

Prolonged overcirculation-induced pulmonary arterial hypertension as a cause of right ventricular failure.

AIMS: Three-month chronic systemic-to-pulmonary shunting in growing piglets has been reported as an early pulmonary arterial hypertension (PAH) model with preserved right ventricular (RV) function. We sought to determine whether prolonged shunting might be associated with more severe PAH and RV failure. METHODS AND RESULTS: Fourteen growing piglets were randomized to a sham operation or the anastomosis of the left innominate artery to the pulmonary arterial trunk. Six months later, the shunt was closed and the animals underwent haemodynamic evaluation followed by tissue sampling for pathobiological assessment. Prolonged shunting had resulted in increased mean pulmonary artery pressure (22 ± 2 versus 17 ± 1 mmHg) and pulmonary arteriolar medial thickness, while cardiac output was decreased. However, RV-arterial coupling was markedly deteriorated, with a ~50% decrease in the ratio of end-systolic to pulmonary arterial elastances (Ees/Ea). Lung tissue expressions of endothelin-1, angiopoietin-1, and bone morphogenetic protein receptor-2 were similarly altered compared with previously observed after 3-month shunting. At the RV tissue level, pro-apoptotic ratio of Bax-to-Bcl-2 expressions and caspase-3 activation were increased, along with an increase in cardiomyocyte size, while expressions in voltage-gated potassium channels (Kv1.5 and Kv2.1) and angiogenic factors (angiopoietin-2 and vascular endothelial growth factor) were decreased. Right ventricular expressions of pro-inflammatory cytokines [interleukin (IL)-1α, IL-1ß, tumour necrosis factor-α (TNF-α)] and natriuretic peptide precursors (NPPA and NPPB) were increased. There was an inverse correlation between RV Ees/Ea and pro-apoptotic Bax/Bcl-2 ratios. CONCLUSIONS: Prolonged left-to-right shunting in piglets does not further aggravate pulmonary vasculopathy, but is a cause of RV failure, which appears related to an activation of apoptosis and inflammation.
