A real-world analysis of outcomes and healthcare costs of patients on perindopril/indapamide/amlodipine single-pill vs. multiple-pill combination in Italy.

OBJECTIVES: This analysis compared adherence, cardiovascular (CV) events and all-cause mortality incidence, and healthcare costs among hypertensive patients treated with perindopril (PER)/indapamide (IND)/amlodipine (AML) in single-pill combination (SPC) vs. multiple-pill combination, in a real-world setting in Italy. METHODS: In this observational retrospective analysis of Italian administrative databases, adult patients treated with PER/IND/AML between 2010 and 2020 were divided into two cohorts: single-pill vs. multiple-pill. Patient data were available for at least one year before and after index date. Propensity score matching (PSM) was applied to reduce selection bias. Adherence was defined as proportion of days covered: non-adherence, <40%; partial adherence, 40-79%, and adherence ≥80%. Mortality incidence and CV events as single, or composite, endpoints were evaluated after first year of follow-up. Healthcare cost analyses were performed from the perspective of the Italian National Health Service. RESULTS: Following PSM, the single-pill cohort included 12 150 patients, and the multiple-pill cohort, 6105. The SPC cohort had a significantly higher percentage of adherent patients vs. the multiple-pill cohort (59.9% vs. 26.9%, P  < 0.001). Following the first year of follow-up, incidence of all-cause mortality, and combined endpoint of all-cause mortality and CV events were lower in the SPC cohort compared with multiple-pill cohort. Average annual direct healthcare costs were lower in the single-pill cohort (€2970) vs. multiple-pill cohort (€3642); cost of all drugs and all-cause hospitalizations were major contributors. CONCLUSION: The SPC of PER/IND/AML, compared with multiple-pill combination, is associated with higher adherence to medication, lower incidence of CV events and mortality, and reduced healthcare costs.

Transgenerational and intergenerational effects of early childhood famine exposure in the cohort of offspring of Leningrad Siege survivors.

Famine exposure during early life development can affect disease risk in late-life period, yet, transmission of phenotypic features from famine-exposed individuals to the next generations has not been well characterized. The purpose of our case-control study was to investigate the association of parental starvation in the perinatal period and the period of early childhood with the phenotypic features observed in two generations of descendants of Leningrad siege survivors. We examined 54 children and 30 grandchildren of 58 besieged Leningrad residents who suffered from starvation in early childhood and prenatal age during the Second World War. Controls from the population-based national epidemiological ESSE-RF study (n = 175) were matched on sex, age and body mass index (BMI). Phenotypes of controls and descendants (both generations, children and grandchildren separately) were compared, taking into account multiple testing. Comparison of two generations descendants with corresponding control groups revealed significantly higher creatinine and lower glomerular filtration rate (GFR), both in meta-analysis and in independent analyses. The mean values of GFR for all groups were within the normal range (GFR less than 60 mL/min/1.73 m2 was recorded in 2 controls and no one in DLSS). Additionally, independent of the creatinine level, differences in the eating pattern were detected: insufficient fish and excessive red meat consumption were significantly more frequent in the children of the Leningrad siege survivors compared with controls. Blood pressure, blood lipids and glucose did not differ between the groups. Parental famine exposure in early childhood may contribute to a decrease in kidney filtration capacity and altered eating pattern in the offspring of famine-exposed individuals.

Adherence to Triple Single-Pill Combination of Perindopril/Indapamide/Amlodipine: Findings from Real-World Analysis in Italy.

INTRODUCTION: Single-pill combination therapy for hypertension is recognized to improve adherence to treatment. However, less is known about the benefits of triple single-pill combinations. This retrospective observational analysis aimed to assess changes in adherence when treatment was switched from perindopril (PER)/indapamide (IND) + amlodipine (AML) to PER/IND/AML single-pill combination, in Italian clinical practice. METHODS: This analysis used data extracted from administrative databases of Italian healthcare entities. Adult patients receiving PER/IND/AML were selected, and the prescription date was considered as the index date. Among them, those who had a prescription for PER/IND + AML during the 12 months before the index date and a prescription of PER/IND/AML during 6 months of follow-up were included. Adherence was calculated as the proportion of days covered (PDC: PDC < 40%, non-adherent; PDC = 40-79%, partially adherent; PDC ≥ 80%, adherent). RESULTS: Among the identified patients, 158 were exposed users and were included in the analysis. When patients were compared before and after switch to triple single-pill combination, the proportion of adherent patients was significantly higher with PER/IND/AML single-pill combination (75.3%) than with PER/IND + AML combination (44.3%) (P < 0.05). Conversely, the proportion of non-adherent patients was lower with the PER/IND/AML single-pill combination (14.6%) vs PER/IND + AML (17.7%) (P < 0.001). CONCLUSION: This real-world analysis showed that switching to a triple single-pill combination could offer an opportunity to improve adherence to antihypertensive treatment in real-life clinical practice.

Medication adherence is defined by the World Health Organization as the "extent to which a person's behavior (in taking medication) corresponds with agreed recommendations from a healthcare provider". Low levels of medication adherence in hypertension have been linked with increased disease burden and with higher costs for patients. Patients with hypertension whose blood pressure is poorly controlled often need to receive more than one pill. Nevertheless, having to take many pills may result in poor adherence, i.e., patients not taking their treatment as prescribed. Combining multiple drugs into a single pill for the management of hypertension is known to improve adherence; however, limited evidence exists about the benefits of triple single-pill combinations compared with equivalent free combinations in real clinical practice. This analysis evaluated changes in adherence before and after patients switched from a three-drug therapy of perindopril/indapamide single-pill + amlodipine (PER/IND + AML) to perindopril/indapamide/amlodipine (PER/IND/AML) taken as a single pill. In this analysis, real-world data from Italian administrative databases covering around 11% of the Italian population were used. Overall, 158 patients were included. More patients were found to be adherent after switch to PER/IND/AML single pill (75.3% vs 44.3% of PER/IND + AML combination). Partially adherent and poorly adherent patients were fewer with PER/IND/AML single-pill combination (10.1% and 14.6%, respectively) compared to PER/IND + AML combination (38.0% and 17.7%, respectively). These findings indicate that switching to a simplified therapy in which all three drugs are taken in one pill may offer an opportunity for increasing the number of patients that are adherent to their medication.

Prevalence and relationship between metabolic syndrome and risk of cardiovascular disease: Evidence from two population-based studies.

BACKGROUND AND AIM: The metabolic syndrome (MetS) has become one of the most important clinical issues in the cardiovascular field for this decade because of the marked increase in cardiovascular (CV) risk associated with a clustering of risk factors. The aim of the current study was to evaluate the relationship between MetS and its components and cardiovascular disease (CVD). METHODS: This population-based cross-sectional study was based on data from two studies carried out in Russia (ESSE-RF) and Italy (PLIC). One sample from each cohort was selected, matching individuals by sex and age. A comparison between samples of MetS components distribution and CV risk, according to SCORE chart, has been conducted. RESULTS: A total of 609 individuals (mean [SD] age 55 [8] years, about 39% males) for each cohort were selected. Almost half of PLIC cohort participants belonged to the moderate CV risk group (47% vs 27%), while in ESSE-RF cohort a relatively higher prevalence of individuals classified in the high and very high risk group was observed (19% vs 11%, 21% vs 6%, respectively). Overall, 43% of ESSE-RF participants were diagnosed with MetS, compared with the 27% of PLIC members (the difference in prevalence becomes 37% vs 21%, considering a more conservative cut-off for waist circumference). Both cohorts showed a trend towards the increase of MetS components moving from the lowest to the highest CV risk class, with a high prevalence of patients with four or five MetS determinants allocated in the high/very high CV risk group. CONCLUSIONS: Developing effective public health strategies for the prevention, detection and treatment of MetS should be an urgent priority to reduce the burden of CVD, not only in subjects at high/very high CV risk, but also in those characterized by a lower risk, as even rare CV events that come from low risk group bring a tangible burden to healthcare systems.

Cardiotonic Steroids Induce Vascular Fibrosis Via Pressure-Independent Mechanism in NaCl-Loaded Diabetic Rats.

Endogenous cardiotonic steroid, marinobufagenin (MBG), induces Fli1-dependent tissue fibrosis. We hypothesized that an increase in MBG initiates the development of aortic fibrosis in salt-loaded rats with type 2 diabetes mellitus (DM2) via pressure-independent mechanism. DM2 was induced by a single intraperitoneal administration of 65 mg/kg streptozotocin to neonatal (4-5 days) male Wistar rats. Eight-week-old DM2 rats received water or 1.8% NaCl (DM-NaCl) solution for 4 weeks (n = 16); half of DM-NaCl rats were treated with anti-MBG monoclonal antibody (mAb) (DM-NaCl-AB) during week 4 of salt loading; control intact rats received water (n = 8/group). Blood pressure, MBG, erythrocyte Na/K-ATPase activity, aortic weights, levels of fibrosis markers (Fli1, protein kinase Cδ, transforming growth factor-ß1, receptors of the transforming growth factor beta5, fibronectin, collagen-1), and sensitivity of the aortic explants to the vasorelaxant effect of sodium nitroprusside were assessed. No changes in systolic blood pressure were observed while erythrocyte Na/K-ATPase was inhibited by 30%, plasma MBG was doubled, and aortic markers of fibrosis became elevated in DM-NaCl rats versus control. Treatment of DM-NaCl rats with anti-MBG mAb activated Na/K-ATPase, prevented increases in aortic weights, and the levels of fibrosis markers returned to the control levels. The responsiveness of the aortic rings from DM-NaCl rats to the relaxant effect of sodium nitroprusside was reduced (half maximal effective concentration (EC50) = 29 nmol/L) versus control rings (EC50 = 7 nmol/L) and was restored by anti-MBG mAb (EC50 = 9 nmol/L). Our results suggest that in salt-loaded diabetic rats, MBG stimulates aortic collagen synthesis in a pressure-independent fashion and that 2 profibrotic mechanisms, Fli1 dependent and transforming growth factor-ß dependent, underlie its effects.

Marinobufagenin-induced vascular fibrosis is a likely target for mineralocorticoid antagonists.

OBJECTIVE: Endogenous cardiotonic steroids, including marinobufagenin (MBG), stimulate vascular synthesis of collagen. Because mineralocorticoid antagonists competitively antagonize effect of cardiotonic steroids on the Na/K-ATPase, we hypothesized that spironolactone would reverse the profibrotic effects of MBG. METHODS: Experiment 1: Explants of thoracic aortae and aortic vascular smooth muscle cells from Wistar rats were cultured for 24 h in the presence of vehicle or MBG (100 nmol/l) with or without canrenone (10 µmol/l), an active metabolite of spironolactone. Experiment 2: In 16 patients (56 ±â€Š2 years) with resistant hypertension on a combined (lisinopril/amlodipine/hydrochlorothiazide) therapy, we determined arterial pressure, pulse wave velocity, plasma MBG, and erythrocyte Na/K-ATPase before and 6 months after addition of placebo (n = 8) or spironolactone (50 mg/day; n = 8) to the therapy. RESULTS: In rat aortic explants and in vascular smooth muscle cells, pretreatment with MBG resulted in a two-fold rise in collagen-1, and a marked reduction in the sensitivity of the aortic rings to the vasorelaxant effect of sodium nitroprusside following endothelin-1-induced constriction (EC50 = 480 ±â€Š67 vs. 23 ±â€Š3 nmol/l in vehicle-treated rings; P < 0.01). Canrenone blocked effects of MBG on collagen synthesis and restored sensitivity of vascular rings to sodium nitroprusside (EC50 = 17 ±â€Š1 nmol/l). Resistant hypertension patients exhibited elevated plasma MBG (0.42 ±â€Š0.07 vs. 0.24 ±â€Š0.03 nmol/l; P = 0.01) and reduced Na/K-ATPase activity (1.9 ±â€Š0.15 vs. 2.8 ±â€Š0.2 µmol Pi/ml per h, P < 0.01) vs. seven healthy individuals. Six-month administration of spironolactone, unlike placebo treatment, was associated with a decrease in pulse wave velocity and arterial pressure, and with restoration of Na/K-ATPase activity in the presence of unchanged MBG levels. CONCLUSION: MBG-induced vascular fibrosis is a likely target for spironolactone.

WISP1 is a novel adipokine linked to inflammation in obesity.

WISP1 (Wnt1-inducible signaling pathway protein-1, also known as CCN4) is a member of the secreted extracellular matrix-associated proteins of the CCN family and a target gene of the Wingless-type (WNT) signaling pathway. Growing evidence links the WNT signaling pathway to the regulation of adipogenesis and low-grade inflammation in obesity. We aimed to validate WISP1 as a novel adipokine. Human adipocyte differentiation was associated with increased WISP1 expression and secretion. Stimulation of human macrophages with WISP1 led to a proinflammatory response. Circulating WISP1 and WISP1 subcutaneous adipose tissue expression were regulated by weight changes in humans and mice. WISP1 expression in visceral and subcutaneous fat tissue was associated with markers of insulin resistance and inflammation in glucose-tolerant subjects. In patients with nonalcoholic fatty liver disease, we found no correlation among disease activity score, liver fat content, and WISP1 expression. Insulin regulated WISP1 expression in adipocytes in vitro but had no acute effect on WISP1 gene expression in subcutaneous fat tissue in overweight subjects who had undergone hyperinsulinemic clamp experiments. The data suggest that WISP1 may play a role in linking obesity to inflammation and insulin resistance and could be a novel therapeutic target for obesity.

Prevalence of metabolic syndrome components in a population of bank employees from St. Petersburg, Russia.

BACKGROUND: The aim of this study was to assess prevalence of metabolic syndrome and its components according to different criteria in the population of bank employees in St. Petersburg, Russia. METHODS: A total of 1,600 office workers were screened at their working places from the Sberbank state bank in St. Petersburg. All subjects were interviewed by a special questionnaire that included personal data, smoking status, physical activity, alcohol consumption, and medical history. Anthropometry measurements, vital signs, and fasting blood samples were obtained. Serum lipids and plasma glucose were measured. RESULTS: In all, 1,561 responders were included in the final analysis. Hypertension (HTN) was observed in 35.2% of subjects (64% in males and 25.4% in females), abdominal obesity (AO) according to Internation Diabetes Federation (IDF) criteria in 45.6% (51.5% in males and 44.0% in females), high triglyceride levels in 28.4%, low high-density lipoprotein cholesterol (HDL-C) levels in 23.9%, and elevated fasting glucose over 5.6 mmol/L in 28.4% of subjects. AO associated with HTN was observed in 24.3%. Metabolic syndrome according to IDF criteria was diagnosed in 21.5% (17.9% in females and 34.6% in males, P<0.01), and according to Adult Treatment Panel III (ATP III) (2005) criteria in 18.8% of subjects (16.2% in females and 28.4% in males, P<0.01). The correlation between criteria was ρ(S)=0.79. Low physical activity, smoking, and alcohol abuse were associated with metabolic syndrome. CONCLUSIONS: Metabolic syndrome and its distinct components were very prevalent in Russian bank office workers. AO was most prevalent component for females with metabolic syndrome, whereas HTN was most prevalent for males. Coexistence of HTN and AO was the most frequent coupling of metabolic syndrome components. Unhealthy lifestyle characterized the selected group and was associated with metabolic syndrome, especially low physical activity.
