Thiopurines have no impact on outcomes of Crohn's disease patients beyond 12 months of maintenance treatment with infliximab. Dig Liver Dis 2024; 56:737-743. [PMID: 37980274 DOI: 10.1016/j.dld.2023.10.027] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/26/2023] [Revised: 10/23/2023] [Accepted: 10/26/2023] [Indexed: 11/20/2023]
Abstract
BACKGROUND The emergence of new treatments the inflammatory bowel diseases (IBD) raised questions regarding the role of older agents, namely thiopurines. AIMS To clarify the benefits of combination treatment with thiopurines on Crohn's disease (CD) patients in the maintenance phase of infliximab. METHODS In this analysis of the 2-year prospective multicentric DIRECT study, patients were assessed in terms of clinical activity, faecal calprotectin (FC), C-reactive protein (CRP), and infliximab pharmacokinetics. A composite outcome based on clinical- and drug-related items was used to define treatment failure. RESULTS The study included 172 patients; of these, 35.5 % were treated with combination treatment. Overall, 18 % of patients achieved the composite outcome, without statistically significant differences between patients on monotherapy and on combination treatment (21.6% vs 11.5 %, p = 0.098). Median CRP, FC, and infliximab pharmacokinetic parameters were similar in both groups. However, in the sub-analysis by infliximab treatment duration, in patients treated for less than 12 months, the composite outcome was reached in fewer patients in the combination group than in the monotherapy group (7.1% vs 47.1 %, p = 0.021). CONCLUSION In CD patients in maintenance treatment with infliximab, combination treatment does not seem to have benefits over infliximab monotherapy beyond 12 months of treatment duration.

Far-UV-C irradiation promotes synergistic bactericidal action against adhered cells of Escherichia coli and Staphylococcus epidermidis. THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 917:170352. [PMID: 38286293 DOI: 10.1016/j.scitotenv.2024.170352] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/13/2023] [Revised: 01/17/2024] [Accepted: 01/20/2024] [Indexed: 01/31/2024]
Abstract
The contamination of indoor areas is a global health problem that can cause the dispersion of infectious diseases. In that sense, it is urgent to find new strategies applying a lower concentration of the traditional chemicals used for cleaning and disinfection. Ultraviolet radiation (UV), in particular far-UV-C (200-225 nm), has emerged as a successful, powerful, easy-to-apply, and inexpensive approach for bacterial eradication that still requires scientific assessment. This study investigated new strategies for disinfection based on far-UV-C (222 nm) combined with chlorine and mechanical cleaning, providing an innovative solution using low doses. The bactericidal activity of far-UV-C (222 nm) was tested at an intensity of irradiation from 78.4 μW/cm2 to 597.7 μW/cm2 (for 1 min) against Escherichia coli and Staphylococcus epidermidis adhered on polystyrene microtiter plates. It was further tested in combination with mechanical cleaning (ultrasounds for 1 min) and free chlorine (0.1, 0.5, and 1 mg/L for 5 min). The triple combination consisting of mechanical cleaning + free chlorine (0.5 mg/L) + far-UV-C (54 mJ/cm2) was tested against cells adhered to materials found in hospital settings and other public spaces: polyvinyl chloride (PVC), stainless steel (SS), and polyetheretherketone (PEEK). Disinfection with far-UV-C (54 mJ/cm2) and free chlorine at 0.5 mg/L for 5 min allowed a total reduction of culturable E. coli cells and a logarithmic reduction of 2.98 ± 0.03 for S. epidermidis. The triple combination of far-UV-C, free chlorine, and mechanical cleaning resulted in a total reduction of culturable cells for both adhered bacteria. Bacterial adhesion to PVC, SS, and PEEK occurred at distinct extents and influenced the bactericidal activity of the triple combination, with logarithmic reductions of up to three. The overall results highlight that, based on culturability assessment, far-UV-C (54 mJ/cm2) with chlorine (0.5 mg/L; 5 min) and mechanical cleaning (1 min) as an efficient disinfection strategy using mild conditions. The combination of culturability and viability assessment of disinfection is recommended to detect regrowth events and increase the effectiveness in microbial growth control.

Cost-Effectiveness Analysis of Trastuzumab Deruxtecan Versus Trastuzumab Emtansine for Patients With Human Epidermal Growth Factor Receptor 2 Positive Metastatic Breast Cancer in the United States. VALUE IN HEALTH : THE JOURNAL OF THE INTERNATIONAL SOCIETY FOR PHARMACOECONOMICS AND OUTCOMES RESEARCH 2024; 27:153-163. [PMID: 38042333 DOI: 10.1016/j.jval.2023.11.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Revised: 09/20/2023] [Accepted: 11/22/2023] [Indexed: 12/04/2023]
Abstract
OBJECTIVES To assess the cost-effectiveness of trastuzumab deruxtecan compared with trastuzumab emtansine as second-line therapy for patients with human epidermal growth factor receptor 2 positive metastatic breast cancer from a US healthcare sector perspective. METHODS A 3-state partitioned survival model was developed to estimate the cost-effectiveness of trastuzumab deruxtecan compared with trastuzumab emtansine. For both treatments, modeled patients were administered treatment intravenously every 3 weeks indefinitely or until disease progression. Transition parameters were principally derived from the updated DESTINY-Breast03 phase III randomized clinical trial. Costs include drug costs extracted from Centers for Medicare and Medicaid Services average sales price and administrative, adverse event, and third-line therapy costs derived from published literature, measured in 2022 US dollars. Health utilities for health states and disutilities for adverse events were sourced from published literature. Effects were measured in quality-adjusted life years (QALYs). We conducted both probabilistic sensitivity analysis and comprehensive scenario analysis to test model assumptions and robustness, while utilizing a lifetime horizon. RESULTS In our base-case analysis, total costs for trastuzumab deruxtecan were $1 266 945, compared with $820 082 for trastuzumab emtansine. Total QALYs for trastuzumab deruxtecan were 5.09, compared with 3.15 for trastuzumab emtansine. The base-case incremental cost-effectiveness ratio was $230 285/QALY. Probabilistic sensitivity analysis indicated that trastuzumab deruxtecan had an 11.1% probability of being cost-effective at a $100 000 per QALY willingness-to-pay threshold. CONCLUSIONS Despite the higher efficacy of trastuzumab deruxtecan in patients with human epidermal growth factor receptor 2 positive metastatic breast cancer, our findings raise concern regarding its value at current prices.

Abstract
Although breast cancer (BC) is the most common malignancy in women, metastasization to the gastrointestinal tract is rare. We present a 59-year-old woman with simultaneous gastric and colonic metastasis of invasive lobular breast carcinoma. She had been diagnosed with BC and underwent surgery and systemic therapy. Two years later, an increase in tumor markers motivated investigation, including upper and lower gastrointestinal endoscopy, which identified gastric ulcers and mucosal irregularity in the cecum. Histopathological analysis was compatible with gastric and colonic metastases from BC. We highlight the importance of biopsying every endoscopically visible lesion in patients with BC history.

Abstract
AIMS We aimed to explored the association between the use of optimal medical therapy (OMT) in patients with myocardial infarction (AMI) and diabetes mellitus (DM) and clinical outcomes. METHODS Bleeding complications in a Multicenter registry of patients discharged with diagnosis of Acute Coronary Syndrome (BleeMACS) is an international registry that enrolled participants with acute coronary syndrome followed up for at least 1 year across 15 centers from 2003 to 2014. Baseline characteristics and endpoints were analyzed. RESULTS Among 3095 (23.2%) patients with AMI and DM, 1898 (61.3%) received OMT at hospital discharge. OMT was associated with significantly reduced mortality (4.3% vs. 10.8%, p < 0.001), re-AMI (4.4% vs. 8.1%, p < 0.001), and composite endpoint of death/re-AMI (8.0% vs. 17.6%, p < 0.001). No difference was observed among regions. Propensity score matching confirmed that OMT significantly associated with lower mortality. After adjusting for confounding variables, OMT, drug-eluting stents, and complete revascularization were independent protective factors of 1-year mortality, whereas left ventricular ejection fraction and age were risk factors. CONCLUSIONS Guideline-recommended OMT was prescribed at suboptimal frequencies with geographic variations in this worldwide cohort. OMT can improve long-term clinical outcomes in patients with DM and AMI. CLINICAL TRIAL REGISTRATION NCT02466854 June 9, 2015.

Abstract
Background Inflammatory bowel diseases' (IBD) increasing incidence and prevalence place a heavy health and economic burden on society. Objectives This study assesses the burden and cost of IBD in Portugal to support the definition of health policies, resource allocation, and patient care. Methods The burden of disease was expressed using disability-adjusted life years (DALY). Costs were estimated considering the societal perspective, using a prevalence-based model and prices established by law. An expert panel composed of 5 expert Portuguese gastroenterologists and a patient-reported study were conducted to support the cost analysis and fill in information gaps. Results In Portugal, with a prevalence of 24,069 IBD patients and an incidence of 15/100,000, the burden of disease was estimated at 6,067 DALYs: 507 resulting from premature deaths and 5,560 from disability. Total cost was estimated at EUR 146 million per year, with direct costs representing 59%. Average yearly cost per IBD patient is EUR 6,075, where 60% is related to Crohn's disease and 40% to ulcerative colitis (UC). Conclusion This study estimates the annual health burden and cost of IBD in Portugal, thus generating information with the intent to raise awareness of the need to advance health policies as well as better clinical and economic decisions in this pathology.

Abstract
Introduction The incidence of primary colorectal lymphoma in the gastrointestinal tract is very low, the rectum being infrequently affected. The development of this entity in inflammatory bowel disease patients usually occurs in a context of immunosuppression-based therapy, with only a few case reports describing its development in patients presenting no known risk factors. Moreover, the clinical presentation of primary colorectal lymphomas may be difficult to distinguish from an acute flare of ulcerative colitis (UC). Case Presentation We present a case of non-Hodgkin lymphoma of the rectum in a 42-year-old male with a 7-year history of UC and no previous exposure to immunomodulatory agents. He presented with a history of mucous diarrhoea, tenesmus, proctalgia and weight loss, refractory to optimized therapy. A lower gastrointestinal endoscopy was performed revealing a circumferential ulcerated lesion of the rectum, from which histopathological analysis established the diagnosis of a non-Hodgkin diffuse large B-cell lymphoma (DLBCL). Discussion/Conclusion The present case suggests the existence of alternative mechanisms for the development of DLBCL in UC patients. The clinical presentation mimicking an acute flare of UC posed a diagnostic challenge, highlighting the complexity behind the management of UC patients.

Abstract
BACKGROUND Patients with previous acute coronary syndrome (ACS) are at high risk of recurrent adverse cardiovascular events. Recently, prolonged dual antiplatelet therapy (DAPT) and oral anticoagulation therapy (OAT) have been shown to reduce recurrent ischemic events to the expense of an increase in bleeding events. The number of patients potentially eligible for these therapies in real life remains to be determined. METHODS Among ACS patients from five registries and one randomized controlled trial, we assessed the proportion of patients eligible for the PEGASUS strategy only and the proportion of patients eligible for the COMPASS strategy only, and set out the proportion of patients with an overlap between the strategies. FINDINGS Among the 10,048 evaluable patients, we found that 5373 (53.4%) were eligible for the PEGASUS strategy and 3841 (38.2%) were eligible for the COMPASS strategy, with a group of 3444 (34.4%) overlapping between the two strategies. The number of patients eligible for the PEGASUS strategy only was 1929 (19.2%) and the number eligible for the COMPASS strategy only was 397 (4.0%); 4278 (42.6%) were eligible for neither a PEGASUS strategy nor a COMPASS strategy. INTERPRETATION In a large cohort of ACS patients, one in three patients was eligible for either a prolonged DAPT with ticagrelor 60 mg and low-dose aspirin or a dual pathway inhibition approach with rivaroxaban 2.5 mg and low-dose aspirin.

Abstract
The culturing of Leptospira strains from bovine clinical samples is challenging and has resulted in some gaps in securing an epidemiological understanding. Strains related to chronic reproductive leptospirosis in cattle belong to the Sejroe serogroup - not only Hardjoprajitno and Hardjobovis but also Guaricura genotypes. This study analyses the growth of Leptospira strains from serogroup Sejroe in different culture media, with the aim of suggesting better culturing approaches. To meet this objective, two culture media were applied: EMJH and T80/40/LH. In addition, three different cocktails of selective agents were chosen. The combinations of medium and selective additives resulted in 10 different tested formulae. The poor performance of Hardjobovis in EMJH indicated that its growth may represent a possible bias when culturing these strains from bovine samples. The most efficient medium for culturing Hardjobovis was T80/40/LH, while T80/40/LH medium + STAFF combination proved to be the best choice for growth, being recommended for obtaining a higher number of these strains from bovines.

Abstract
Background Treatment of acute myocardial infarction (AMI) patients with prior stroke is a common clinical dilemma. Currently, the application of optimal medical therapy (OMT) and its impact on clinical outcomes are not clear in this patient population. Methods We retrieved 765 AMI patients with prior stroke who underwent percutaneous coronary intervention (PCI) during the index hospitalization from the international multicenter BleeMACS registry. All of the subjects were divided into two groups based on the prescription they were given prior to discharge. Baseline characteristics and procedural variables were compared between the OMT and non-OMT groups. Mortality, re-AMI, major adverse cardiovascular events (MACE), and bleeding were followed-up for 1 year. Results Approximately 5% of all patients presenting with AMI were admitted to the hospital for ischemic stroke. Although the prescription rate of each OMT medication was reasonably high (73.3%-97.3%), 47.7% lacked at least one OMT medication. Patients receiving OMT showed a significantly decreased occurrence of mortality (4.5% vs 15.1%, p < 0.001), re-AMI (4.2% vs 9.3%, p = 0.004), and the composite endpoint of death/re-AMI (8.6% vs 20.5%, p < 0.001) compared to those without OMT. No significant difference was observed between the groups regarding bleeding. After adjusting for confounding factors, OMT was the independent protective factor of 1-year mortality, while age was the independent risk factors. Conclusions OMT at discharge was associated with a significantly lower 1-year mortality of patients with AMI and prior stroke in clinical practice. However, OMT was provided to just half of the eligible patients, leaving room for substantial improvement. Clinical Trial Registration NCT02466854.

Abstract
In seasonal breeders, reproductive seasonality can have a substantial influence on the efficiency of assisted reproductive technologies. This study assessed seasonal effects on cleavage and blastocyst rates, as well as on quality of invitro-produced (IVP) goat embryos over 18 months. In total, 2348 (autumn: 811, spring: 404, summer: 639, and, winter: 494) cumulus–oocyte complexes (COC) were recovered from slaughterhouse ovaries during 49 replicates (autumn: 17, spring: 7, summer: 15, and, winter: 10) and matured in TCM-199 with 10ng mL−1 epidermal growth factor and 100µM cysteamine for 22h at 38.8°C (5% CO2 in air). Matured oocytes were fertilized with frozen/thawed semen in synthetic oviductal fluid (SOF) with 10% oestrus sheep serum. Sperm and oocytes were co-incubated for 16h at 38.8°C in a humidified atmosphere of 5% CO2 in air. Presumptive zygotes were cultured in SOF medium supplemented with bovine serum albumin (3mg mL−1) for 8 days at 38.8°C in a humidified atmosphere of 5% O2, 5% CO2 and 90% N2. At Day 2, 10% fetal calf serum was added to the culture droplets. The embryos produced were fixed and stained with Hoechst to count their total number of cells, under an epifluorescence microscope. The results of cleavage and blastocyst rates, including hatching rate, from each routine of IVEP were considered as replicates. These data were tested for normality by the Shapiro-Wilk test, before being subjected to ANOVA, followed by Tukey HSD test. The odds ratio (OR) among seasons (autumn: breeding; spring: anoestrus) were calculated. Values of P<0.05 were considered as significant, and the data reported are mean±s.e.m. Cleavage rate was lower (P<0.05) in spring (51±7.1%) than in either autumn (72±2.1%) or summer (71±2.0%) while winter (66±4.1%) had an intermediate value, being similar (P> 0.05) to all others. Indeed, greater possibility of cleavage was observed in autumn (OR: 2.43) and summer (OR: 2.39) compared with spring. The blastocyst rate from cleaved embryos was greater (P <0.05) in autumn (73±2.7%) than in spring (55±2.6%; OR: 2.18). As a result, the blastocyst formation rate from the initial number of COC entering IVM was greater (P<0.05) in autumn (52±2.5%) than in spring: 28±4.7%, summer: 45±2.3%, and winter: 42±2.1%; indeed, the spring season resulted in the lowest rate (P<0.05), compared with other seasons. Moreover, the OR in the blastocyst rate from initial number of COC was greater (P<0.05) in autumn compared with all other seasons and lower in spring compared with winter (OR: 0.54) and summer (OR: 0.48). There were no differences (P> 0.05) in the embryo hatching (mean: 66±2.0%) and blastocyst cell number (mean: 193±2.0 cells). In conclusion, the breeding season (autumn) leads to improved oocyte developmental competence, resulting in greater cleavage and blastocyst yield, whereas embryo quality remained similar throughout the year. Further studies at the molecular level might indicate the mechanisms involved and provide clues to alleviate the negative effect of season.

Abstract
Background:
The rate of intracranial haemorrhage after an acute coronary syndrome has been studied in detail in the era of thrombolysis; however, in the contemporary era of percutaneous coronary intervention, most of the data have been derived from clinical trials. With this background, we aim to analyse the incidence, timing, predictors and prognostic impact of post-discharge intracranial haemorrhage in patients with acute coronary syndrome undergoing percutaneous coronary intervention.
Methods:
We analysed data from the BleeMACS registry (patients discharged for acute coronary syndrome and undergoing percutaneous coronary intervention from Europe, Asia and America, 2003–2014). Analyses were conducted using a competing risk framework. Uni and multivariate predictors of intracranial haemorrhage were assessed using the Fine–Gray proportional hazards regression analysis. The endpoint was 1-year post-discharge intracranial haemorrhage.
Results:
Of 11,136 patients, 30 presented with intracranial haemorrhage during the first year (0.27%). The median time to intracranial haemorrhage was 150 days (interquartile range 55.7–319.5). The fatality rate of intracranial haemorrhage was very high (30%). After multivariate analysis, only age (subhazard ratio 1.05, 95% confidence interval 1.01–1.07) and prior stroke/transient ischaemic attack (hazard ratio 3.29, 95% confidence interval 1.36–8.00) were independently associated with a higher risk of intracranial haemorrhage. Hypertension showed a trend to associate with higher intracranial haemorrhage rate. The combination of older age (⩾75 years), prior stroke/transient ischaemic attack, and/or hypertension allowed us to identify most of the patients with intracranial haemorrhage (86.7%). The annual rate of intracranial haemorrhage was 0.1% in patients with no risk factors, 0.2% in those with one factor, 0.6% in those with two factors and 1.3% in those with three factors.
Conclusion:
The incidence of intracranial haemorrhage in the first year after an acute coronary syndrome treated with percutaneous coronary intervention is low. Advanced age, previous stroke/transient ischaemic attack, and hypertension are the main predictors of increased intracranial haemorrhage risk.

Abstract
INTRODUCTION Real-life data comparing clopidogrel, prasugrel, and ticagrelor for unselected patients undergoing percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) are lacking, as are data for the temporal distribution of ischemic and bleeding risks. METHODS A total of 19,825 patients were enrolled from the RENAMI and BleeMACS registries. Both were multicenter, retrospective, observational registries including the data and outcomes of consecutive patients with ACS who underwent primary PCI and were discharged with dual antiplatelet therapy (DAPT). We evaluated the long-term outcome stratified by the different antiplatelet agents. RESULTS A total of 14,105 patients (71.2%) were treated with clopidogrel, 2364 patients (11.9%) with prasugrel and 3356 patients (16.9%) with ticagrelor. After propensity score matching, at 1 year, prasugrel reduced the incidence of net adverse clinical events (NACE; a composite endpoint of all-cause death, myocardial infarction [MI] and Bleeding Academic Research Consortium [BARC] 3-5 bleeding) (4.2% vs.7.6%, p = 0.002) and of major adverse cardiovascular events (MACE; a composite endpoint of death and MI) compared with clopidogrel (2.6% vs. 5.2%, p = 0.007). Ticagrelor decreased rates of MACE compared with clopidogrel (2.7% vs. 6.2%, p < 0.001), but not of NACE (6.6% vs. 8.7%, p = 0.07). Ticagrelor presented similar performance in terms of MACE compared with prasugrel (2.8% vs. 2.4%, p = 0.56), with a trend towards a reduction in MI (0.2% vs. 0.4%, p = 0.56), but with higher risk of BARC 3-5 bleedings (3.8% vs. 1.7%, p = 0.04). In the daily risk analysis, clopidogrel presented a binomial distribution with a peak of ischemic risk at 3 months, which decreased towards bleedings; prasugrel had a constant equivalence between opposite risks; and ticagrelor constantly reduced recurrent MIs despite higher risk of BARC 3-5 events. CONCLUSION In real life, ticagrelor is more effective in reducing ischemic events during the first year after ACS, despite an increased risk of major bleedings, while prasugrel assures a better balance between ischemic and bleeding recurrent events.

Abstract
The association between prior stroke/transient ischemic attack (TIA) and clinical outcomes in patients with acute coronary syndrome (ACS) has not been well explored. We evaluated the impact of prior stroke/TIA on this specific patient population. We conducted an international multicenter study including 15 401 patients with ACS from the Bleeding Complications in a Multicenter Registry of Patients Discharged With Diagnosis of Acute Coronary Syndrome registry. They were divided into 2 groups: patients with and without prior stroke/TIA. The primary end point was death at 1-year follow-up. Prior stroke/TIA was associated with higher rate of 1-year death (8.7% vs 3.4%; P < .001). It was an independent predictor of 1-year death even after adjustment for confounding variables (odds ratio, 1.705; 95% confidence interval, 1.046-2.778; P = .032). Besides, patients with prior stroke/TIA had significantly increased 1-year reinfarction (5.6% vs 3.8%, P = .015), in-hospital bleeding (8.7% vs 5.8%, P < .001), and 1-year bleeding (5.2% vs 3.0%, P < .001). No difference of antithrombotic therapies or dual antiplatelet therapy (DAPT) types on outcomes was observed in patients with prior stroke/TIA. Prior stroke/TIA was associated with higher 1-year death for patients with ACS who underwent percutaneous coronary intervention. No benefits or harms were observed with different antithrombotic therapies or DAPT types in these patients.

Abstract
BACKGROUND AND AIMS Golimumab has an established exposure-response relationship in patients with ulcerative colitis [UC]. However, the association of serum golimumab trough levels [TL] with objective markers of disease activity, such as endoscopic and histological activity scores and concentrations of biomarkers, remains less understood. This report describes the relationship of serum golimumab TL at the end of the induction period [Week 6] with clinical, endoscopic, histological, and biomarker parameters. METHODS This was an open-label, uncontrolled, prospective and interventional study. Moderate to severely active UC patients naïve to biologic therapy were treated with golimumab. Serum golimumab TL and faecal calprotectin levels were measured at baseline [Week 0 of induction] and Week 6. RESULTS A total of 34 patients completed the induction phase [Week 6] and were included in this analysis. Overall, 47.1% and 14.7% of patients achieved clinical response and remission with significantly higher serum golimumab TL in patients with early response or remission [3.7 μg/mL vs 1.3 μg/mL, p = 0.0013; and 3.1 μg/mL vs 1.7 μg/mL, p = 0.0164, respectively]. In addition, golimumab TL were significantly higher in patients achieving histological remission [4.2 μg/mL vs 1.7 μg/mL, p = 0.0049]. Week 6 golimumab TL were inversely correlated with the total Mayo score [rs = -0.546; p = 0.0008], the Mayo endoscopic subscore [rs = -0.381; p = 0.0262], the Geboes histological activity score [rs = -0.464; p = 0.0057], and faecal calprotectin levels [rs = -0.497; p = 0.0044]. CONCLUSIONS A higher early exposure to golimumab is associated with a better objective response in active UC patients and appears to drive the outcome at Week 6.

Abstract
Abstract
Aims
The aim of the present study was to establish the safety and efficacy profile of prasugrel and ticagrelor in real-life acute coronary syndrome (ACS) patients with renal dysfunction.
Methods and results
All consecutive patients from RENAMI (REgistry of New Antiplatelets in patients with Myocardial Infarction) and BLEEMACS (Bleeding complications in a Multicenter registry of patients discharged with diagnosis of Acute Coronary Syndrome) registries were stratified according to estimated glomerular filtration rate (eGFR) lower or greater than 60 mL/min/1.73 m2. Death and myocardial infarction (MI) were the primary efficacy endpoints. Major bleedings (MBs), defined as Bleeding Academic Research Consortium bleeding types 3 to 5, constituted the safety endpoint. A total of 19 255 patients were enrolled. Mean age was 63 ± 12; 14 892 (77.3%) were males. A total of 2490 (12.9%) patients had chronic kidney disease (CKD), defined as eGFR <60 mL/min/1.73 m2. Mean follow-up was 13 ± 5 months. Mortality was significantly higher in CKD patients (9.4% vs. 2.6%, P < 0.0001), as well as the incidence of reinfarction (5.8% vs. 2.9%, P < 0.0001) and MB (5.7% vs. 3%, P < 0.0001). At Cox multivariable analysis, potent P2Y12 inhibitors significantly reduced the mortality rate [hazard ratio (HR) 0.82, 95% confidence interval (CI) 0.54–0.96; P = 0.006] and the risk of reinfarction (HR 0.53, 95% CI 0.30–0.95; P = 0.033) in CKD patients as compared to clopidogrel. The reduction of risk of reinfarction was confirmed in patients with preserved renal function. Potent P2Y12 inhibitors did not increase the risk of MB in CKD patients (HR 1.00, 95% CI 0.59–1.68; P = 0.985).
Conclusion
In ACS patients with CKD, prasugrel and ticagrelor are associated with lower risk of death and recurrent MI without increasing the risk of MB.

Impact of renin-angiotensin system blockade on the prognosis of acute coronary syndrome based on left ventricular ejection fraction. ACTA ACUST UNITED AC 2019; 73:114-122.

Abstract
INTRODUCTION AND OBJECTIVES For patients with acute coronary syndrome (ACS) treated with percutaneous coronary intervention (PCI), it is unclear whether angiotensin-converting enzyme inhibitors (ACEI) or angiotensin receptor blockers (ARB) are associated with reduced mortality, particularly with preserved left ventricular ejection fraction (LVEF). The goal of this study was to determine the association between ACEI/ARB and mortality in ACS patients undergoing PCI, with and without reduced LVEF. METHODS Data from the BleeMACS registry were used. The endpoint was 1-year all-cause mortality. The prognostic value of ACEI/ARB was tested after weighting by survival-time inverse probability and after adjustment by Cox regression, propensity score, and instrumental variable analysis. RESULTS Among 15 401 ACS patients who underwent PCI, ACEI/ARB were prescribed in 75.2%. There were 569 deaths (3.7%) during the first year after hospital discharge. After multivariable adjustment, ACEI/ARB were associated with lower 1-year mortality, ≤ 40% (HR, 0.62; 95%CI, 0.43-0.90; P=.012). The relative risk reduction of ACEI/ARB in mortality was 46.1% in patients with LVEF ≤ 40%, and 15.7% in patients with LVEF> 40% (P value for treatment-by-LVEF interaction=.008). For patients with LVEF> 40%, ACEI/ARB was associated with lower mortality only in ST-segment elevation myocardial infarction (HR, 0.44; 95%CI, 0.21-0.93; P=.031). CONCLUSION The benefit of ACEI/ARB in decreasing mortality after an ACS in patients undergoing PCI is concentrated in patients with LVEF ≤ 40%, and in those with LVEF> 40% and ST-segment elevation myocardial infarction. In non-ST-segment elevation-ACS patients with LVEF> 40%, further studies are needed to assess the prognostic impact of ACEI/ARB.

Abstract
BACKGROUND Ulcerative colitis [UC] is a chronic inflammatory disease often accompanied by severe and distressing symptoms that, in some patients, might require a surgical intervention [colectomy]. This study aimed at determining the risk of experiencing progressive disease or requiring colectomy. MATERIAL AND METHODS This was a multicentre study: patients' data [n = 1481] were retrieved from the Portuguese database of inflammatory bowel disease patients. Bayesian networks and logistic regression were used to build risk matrices concerning the outcomes of interest. RESULTS The derivation cohort included a total of 1210 patients, of whom 6% required a colectomy and 37% had progressive disease [over a median follow-up period of 12 syears]. The risk matrices show that previously hospitalised patients with extensive disease, who are not on immunomodulators and who are refractory to corticosteroid treatment, are the ones at the highest risk of undergoing a colectomy [88%]; whereas male patients, with extensive disease and less than 40 years old at diagnosis, are the ones at the highest risk of experiencing progressive disease [72%]. These results were internally and externally validated, and the AUC [area under the curve] of the ROC [receiver operating characteristic] analysis for the derivation cohort yielded a high discriminative power [92% for colectomy and 72% for progressive disease]. CONCLUSIONS This study allowed the construction of risk matrices that can be used to accurately predict a UC patient's likelihood of requiring a colectomy or of facing progressive disease, and can be used to individualise therapeutic strategies.

Abstract
AIM To test the cross-immunogenicity of anti-CT-P13 IBD patients' sera to CT-P13/infliximab originator and the comparative antigenicity evoked by CT-P13/infliximab originator sera. METHODS Sera of patients with IBD with measurable anti-CT-P13 antibodies were tested for their cross-reactivity to 5 batches of infliximab originator and CT-P13. Anti-drug antibody positive sera from treated patients were used to compare antigenic epitopes. RESULTS All 42 anti-CT-P13 and 37 anti-infliximab originator IBD sera were cross-reactive with infliximab originator and CT-P13 respectively. Concentration of anti-drug antibodies against infliximab originator or CT-P13 were strongly correlated both for IgG1 and IgG4 (P < 0.001). Anti-CT-P13 sera of patients with IBD (n = 32) exerted similar functional inhibition on CT-P13 or infliximab originator TNF binding capacity and showed reduced binding to CT-P13 in the presence of five different batches of CT-P13 and infliximab originator. Anti-CT-P13 and anti-infliximab originator IBD sera selectively enriched phage-peptides from the VH (CDR1 and CDR3) and VL domains (CDR2 and CDR3) of infliximab. Sera reactivity detected major infliximab epitopes in these regions of infliximab in 60%-79% of patients, and no significant differences were identified between CT-P13 and infliximab originator immunogenic sera. Minor epitopes were localised in framework regions of infliximab with reduced antibody reactivity shown, in 30%-50% of patients. Monoclonal antibodies derived from naïve individuals and ADA-positive IBD patients treated with CT-P13 provided comparable epitope specificity to five different batches of CT-P13 and infliximab originator. CONCLUSIONS These results strongly support a similar antigenic profile for infliximab originator and CT-P13, and point toward a safe switching between the two drugs in anti-drug antibody negative patients.

Abstract
PURPOSE The aim was to evaluate prognostic value of beta-blocker (BB) administration in acute coronary syndromes (ACS) patients in the percutaneous coronary intervention (PCI) era. METHODS AND RESULTS The BleeMACS project is a multicenter, observational, retrospective registry enrolling patients with ACS worldwide in 15 hospitals. Patients discharged with BB therapy were compared to those discharged without a BB before and after propensity score with matching. The primary endpoint was all-cause mortality at 1 year. Secondary endpoints included in-hospital reinfarction, in-hospital heart failure, 1-year myocardial infarction, 1-year bleeding and 1-year composite of death and recurrent myocardial infarction. After matching, 2935 patients for each group were enrolled. The primary endpoint of 1-year death was significantly lower in the group on BB therapy (4.5 vs 7%, p < 0.05), while only a trend was noted for recurrent acute myocardial infarction (4.5 vs 4.9%, p = 0.54). These results were consistent for patients older than 80 years of age, for ST-elevation myocardial infarction (STEMI) patients, and for those discharged with complete versus incomplete revascularization, but not for non-STEMI/unstable angina patients. CONCLUSIONS BB therapy was related to 1-year lower risk of all-cause mortality, independently from completeness of revascularization, admission diagnosis, age and ejection fraction. Randomized controlled trials for patients treated with PCI for ACS should be performed.

Abstract
Anthropogenic activities such as agriculture, industry, and mining have contributed significantly to the accumulation of heavy metals in the soil, which in turn cause problems to human health and to the environment. The present work aims to study the effects of nickel (Ni) on the development of tomato plants, the risks to human health associated to the consumption of contaminated tomatoes, and the consequences to the environment. The experiment was carried out in greenhouse environment for a period of 120 days, and the plants were cultivated in soils with four different concentrations of Ni: 0, 35, 70, and 105 mg kg-1. The concentration of nickel in each part (root, stem, leaf, and fruit) of the tomato plant was measured at four different stages of the cycle: 30, 60, 90, and 120 days, by inductively coupled plasma optical emission spectrometer (ICP-OES). At the end of the cycle, the concentration of certain macro- and micronutrients was also determined and related to the corresponding Ni concentration in the soil. The distribution of Ni in the parts of the plant was analyzed from the bioaccumulation factor temporal behavior. Nickel concentrations found in the fruit were too low to pose a risk to human health. As a result of this research, it was verified that soils with nickel concentrations close to 70 mg kg-1, which is the limit established by the CONAMA resolution (420/2009), may actually represent an optimum concentration value for the development of tomato plants. It also increases productivity per plant and reduces the use of resources such as water and agricultural inputs.

Abstract
BACKGROUND A poor ability of recommended risk scores for predicting in-hospital bleeding has been reported in elderly patients with acute coronary syndromes (ACS). No study assessed the prediction of post-discharge bleeding in the elderly. The new BleeMACS score (Bleeding complications in a Multicenter registry of patients discharged with diagnosis of Acute Coronary Syndrome), was designed to predict post-discharge bleeding in ACS patients. We aimed to assess the predictive ability of the BleeMACS score in elderly patients. METHODS We assessed the incidence and characteristics of severe bleeding after discharge in ACS patients aged ≥ 75 years. Bleeding was defined as any intracranial bleeding or bleeding leading to hospitalization and/or red blood transfusion, occurring within the first year after discharge. We assessed the predictive ability of the BleeMACS score according to age by Fine-Gray proportional hazards regression analysis, calculating receiver-operating characteristic (ROC) curves and the area under the ROC curves (AUC). RESULTS The BleeMACS registry included 15,401 patients of whom 3,376/15,401 (21.9%) were aged ≥ 75 years. Elderly patients were more commonly treated with clopidogrel and less often treated with ticagrelor or prasugrel. Of 3,376 elderly patients, 190 (5.6%) experienced post-discharge bleeding. The incidence of bleeding was moderately higher in elderly patients (hazard ratio [HR], 2.31, 95% confidence interval [CI], 1.92-2.77). The predictive ability of the BleeMACS score was moderately lower in elderly patients (AUC, 0.652 vs. 0.691, p = 0.001). CONCLUSION Elderly patients with ACS had a significantly higher incidence of post-discharge bleeding. Despite a lower predictive ability in older patients, the BleeMACS score exhibited an acceptable performance in these patients.

Abstract
The mechanisms that enable preservation of gut mucosal integrity during persistent viral replication and inherent inflammation remain unclear. Here, we investigated, for the first time, gut homeostasis in HIV-2 infection, a naturally occurring form of attenuated HIV disease. We found viral replication in both sigmoid and ileum of asymptomatic HIV-2+ patients (range: 240-851 circulating CD4+T-cells per μl) despite their undetectable viremia, accompanied by interferon-γ-producing CD8 T-cell expansion, irrespective of antiretroviral treatment. Nevertheless, there was no CD4 T-cell depletion, and Foxp3+ and IL-17- or IL-22-producing CD4 T-cell numbers were unaffected. Moreover, IL-22-producing innate lymphoid cells and IL-22-induced antimicrobial peptides and mucins were maintained. In agreement, the epithelium histology was preserved, including tight junction protein zonula occludens (ZO-1) levels. Furthermore, in vitro infection of colon epithelia with primary isolates revealed no HIV-2 impact on ZO-1 expression. Notably, sigmoid transcriptional levels of CCL20 and CCL28 were significantly increased, in direct correlation with GM-CSF, indicating a local response able to enhance CD4 T-cell recruitment. In conclusion, maintenance of mucosal integrity in HIV-2 infection was associated with T-cell recruitment responses, potentially counteracting CD4 T-cell depletion due to HIV-2 replication. These data have unique implications for the design of therapies targeting gut homeostasis in HIV-1 infection and other chronic inflammatory settings.

Abstract
Introduction Crohn’s disease (CD) is a chronic inflammatory bowel disease known to carry a high risk of disabling and many times requiring surgical interventions. This article describes a decision-tree based approach that defines the CD patients’ risk or undergoing disabling events, surgical interventions and reoperations, based on clinical and demographic variables. Materials and methods This multicentric study involved 1547 CD patients retrospectively enrolled and divided into two cohorts: a derivation one (80%) and a validation one (20%). Decision trees were built upon applying the CHAIRT algorithm for the selection of variables. Results Three-level decision trees were built for the risk of disabling and reoperation, whereas the risk of surgery was described in a two-level one. A receiver operating characteristic (ROC) analysis was performed, and the area under the curves (AUC) Was higher than 70% for all outcomes. The defined risk cut-off values show usefulness for the assessed outcomes: risk levels above 75% for disabling had an odds test positivity of 4.06 [3.50–4.71], whereas risk levels below 34% and 19% excluded surgery and reoperation with an odds test negativity of 0.15 [0.09–0.25] and 0.50 [0.24–1.01], respectively. Overall, patients with B2 or B3 phenotype had a higher proportion of disabling disease and surgery, while patients with later introduction of pharmacological therapeutic (1 months after initial surgery) had a higher proportion of reoperation. Conclusions The decision-tree based approach used in this study, with demographic and clinical variables, has shown to be a valid and useful approach to depict such risks of disabling, surgery and reoperation.

Abstract
OBJECTIVE Our objective was to define the most appropriate treatment for acute coronary syndrome (ACS) in patients with malignancy. METHODS AND RESULTS The BleeMACS project is a worldwide multicenter observational prospective registry in 16 hospitals enrolling patients with ACS undergoing percutaneous coronary intervention. Primary endpoints were death, re-infarction, and major adverse cardiac events (MACE; composite of death and re-infarction) after 1 year of follow-up. The secondary endpoint was bleeding events during follow-up. We performed sub-study analyses according to whether β-blockers (BBs), angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs), statins, or proton pump inhibitors (PPIs) were prescribed at discharge. We also calculated the propensity score for optimal medical therapy (OMT; combination of BB, ACEI/ARB, and statins). The study included 926 patients. According to the multivariate analysis, ACEIs/ARBs (hazard ratio [HR] 0.58, 95 % confidence interval [CI] 0.36-1.94; p = 0.03) and statins (HR 0.37, 95 % CI 0.23-0.61; p < 0.01) reduced the risk of MACE, while the effects of BBs (HR 0.85, 95 % CI 0.55-1.32; p = 0.48) and PPIs (HR 1.33, 95 % CI 0.83-2.12; p = 0.23) were not significant. OMT was prescribed at discharge in 300 (32.4 %) patients; after propensity score analysis, OMT showed a significant reduction in death (3 % vs. 12.5 %, HR 0.21, 95 % CI 0.1-0.4; log-rank p < 0.001) and MACE (6.7 vs. 15.2 %, log-rank p = 0.01). CONCLUSION In patients with ACS and malignancy, OMT reduces the risk of adverse events at 1 year; in particular, ACEIs/ARBs and statins were the most protective drugs.

Contraceptive choices pre and post pregnancy in adolescence. J Pediatr Adolesc Gynecol 2015; 28:24-28. [PMID: 25444052 DOI: 10.1016/j.jpag.2014.02.004] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2013] [Revised: 02/03/2014] [Accepted: 02/10/2014] [Indexed: 10/24/2022]
Abstract
STUDY OBJECTIVE The main aim of this study is to evaluate the impact of adolescent pregnancy in the future contraceptive choices. A secondary aim is to verify whether these choices differ from those made after an abortion. DESIGN Retrospective study. SETTING Adolescent Unit of a tertiary care center. PARTICIPANTS 212 pregnant teenagers. INTERVENTIONS Medical records review. MAIN OUTCOME MEASURES Intended pregnancy rate and contraceptive methods used before and after pregnancy. For contraceptive choices after pregnancy we considered: Group 1--teenagers who continued their pregnancy to delivery (n = 106) and Group 2--the same number of adolescents who chose to terminate their pregnancy. RESULTS The intended pregnancy rate was 14.2%. Prior to a pregnancy continued to delivery, the most widely used contraceptive method was the male condom (50.9%), followed by oral combined contraceptives (28.3%); 18.9% of adolescents were not using any contraceptive method. After pregnancy, contraceptive implant was chosen by 70.8% of subjects (P < .001) and the oral combined contraceptives remained the second most frequent option (17.9%, P = .058). Comparing these results with Group 2, we found that the outcome of the pregnancy was the main factor in the choices that were made. Thus, after a pregnancy continued to delivery, adolescents prefer the use of LARC [78.4% vs 40.5%, OR: 5,958 - 95% (2.914-12.181), P < .001)], especially contraceptive implants [70.8% vs 38.7%, OR: 4.371 - 95% (2.224-8.591), P < .001], to oral combined contraceptives [17.9% vs 57.5%, OR: 0.118 - 95% CI (0.054-0.258), P < .001]. CONCLUSION Adolescent pregnancy and its outcome constitute a factor of change in future contraceptive choice.

Clinical and genetic factors predicting response to therapy in patients with Crohn's disease. United European Gastroenterol J 2014; 2:47-56.

Abstract
AIM To identify clinical and/or genetic predictors of response to several therapies in Crohn's disease (CD) patients. METHODS We included 242 patients with CD (133 females) aged (mean ± standard deviation) 39 ± 12 years and a disease duration of 12 ± 8 years. The single-nucleotide polymorphisms (SNPs) studied were ABCB1 C3435T and G2677T/A, IL23R G1142A, C2370A, and G9T, CASP9 C93T, Fas G670A and LgC844T, and ATG16L1 A898G. Genotyping was performed with real-time PCR with Taqman probes. RESULTS Older patients responded better to 5-aminosalicylic acid (5-ASA) and to azathioprine (OR 1.07, p = 0.003 and OR 1.03, p = 0.01, respectively) while younger ones responded better to biologicals (OR 0.95, p = 0.06). Previous surgery negatively influenced response to 5-ASA compounds (OR 0.25, p = 0.05), but favoured response to azathioprine (OR 2.1, p = 0.04). In respect to genetic predictors, we observed that heterozygotes for ATGL16L1 SNP had a significantly higher chance of responding to corticosteroids (OR 2.51, p = 0.04), while homozygotes for Casp9 C93T SNP had a lower chance of responding both to corticosteroids and to azathioprine (OR 0.23, p = 0.03 and OR 0.08, p = 0.02,). TT carriers of ABCB1 C3435T SNP had a higher chance of responding to azathioprine (OR 2.38, p = 0.01), while carriers of ABCB1 G2677T/A SNP, as well as responding better to azathioprine (OR 1.89, p = 0.07), had a lower chance of responding to biologicals (OR 0.31, p = 0.07), which became significant after adjusting for gender (OR 0.75, p = 0.005). CONCLUSIONS In the present study, we were able to identify a number of clinical and genetic predictors of response to several therapies which may become of potential utility in clinical practice. These are preliminary results that need to be replicated in future pharmacogenomic studies.
