Left-sided infective endocarditis caused by Streptococcus agalactiae: rare and serious.

A comparative study of the behaviour of left-sided infective endocarditis (left-sided IE) due to Streptococcus agalactiae (GBS) with left-sided IE caused by Staphylococcus aureus (SA). A prospective, multicentre cohort study in eight public hospitals in Spain, from January 1984 to December 2015; comparative analysis and factors associated with mortality. In total, there were 1754 episodes of left-sided IE; 41 (2.3%) caused by GBS vs. 344 (19.6%) due to SA, definitive IE 39 vs. 324 cases, males, 25 vs. 213, respectively. There were no differences in age or comorbidity, and healthcare-associated acquirement was 10% vs. 43%, p 0.001. Transthoracic echocardiogram (TTE) was performed in 95% vs. 96.8% and a transesophageal echocardiogram (TEE) in 61% vs. 56%. Vegetations were detected in 80% and measured > 1 cm in a similar proportion. It affected native valves in 85.4% vs. 82.6% and late prosthetic valve in 14.6% vs. 9.6%. The course was acute in both groups. There were more skin manifestations in SA left-sided IE, 7.3% vs. 32%, p 0.001. Both groups had similar complications, but in SA, there was more renal failure, 24% vs. 45%, p 0.010. Surgical risk and operated patients were similar. Mortality was proportionally higher in the SA group, without significance 29% vs. 43% (150), p 0.09. Heart failure, septic shock and neurological deterioration conditioned mortality: HR 1.96, 1.69 and 1.37 (CI 95% 1.40-2.73; 1.19-2.39 and 0.99-1.88 respectively) and to a lesser degree SA as aetiology agent and age. Left-sided IE caused by GBS is similar in severity to left-sided IE caused by SA.

Gentamicin may have no effect on mortality of staphylococcal prosthetic valve endocarditis.

PURPOSE: To analyze the influence of adding gentamicin to a regimen consisting of ß-lactam or vancomycin plus rifampicin on survival in patients suffering from Staphylococcal prosthetic valve endocarditis (SPVE). METHODS: From January 2008 to September 2016, 334 patients with definite SPVE were attended in the participating hospitals. Ninety-four patients (28.1%) received treatment based on ß-lactam or vancomycin plus rifampicin and were included in the study. Variables were analyzed which related to patient survival during admission, including having received treatment with gentamicin. RESULTS: Seventy-seven (81.9%) were treated with cloxacillin (or vancomycin) plus rifampicin plus gentamicin, and 17 patients (18.1%) received the same regimen without gentamicin. The causative microorganism was Staphylococcus aureus in 40 cases (42.6%) and coagulase-negative staphylococci in 54 cases (57.4%). Overall, 40 patients (42.6%) died during hospital admission, 33 patients (42.9%) in the group receiving gentamicin and 7 patients in the group that did not (41.2%, P = 0.899). Worsening renal function was observed in 42 patients (54.5%) who received gentamicin and in 9 patients (52.9%) who did not (p = 0.904). Heart failure as a complication of endocarditis (OR: 4.58; CI 95%: 1.84-11.42) and not performing surgery when indicated (OR: 2.68; CI 95%: 1.03-6.94) increased mortality. Gentamicin administration remained unrelated to mortality (OR: 1.001; CI 95%: 0.29-3.38) in the multivariable analysis. CONCLUSIONS: The addition of gentamicin to a regimen containing vancomycin or cloxacillin plus rifampicin in SPVE was not associated to better outcome.

Infective endocarditis in patients with bicuspid aortic valve: Clinical characteristics, complications, and prognosis. / Endocarditis infecciosa sobre válvula aórtica bicúspide: características clínicas, complicaciones y pronóstico.

INTRODUCTION: Bicuspid aortic valve (BAV) is the most frequent congenital cardiac disease. It is associated to a higher risk of cardiovascular complications, including infective endocarditis (IE). METHODS: Retrospective, observational and single centre study that included all patients with IE diagnosed between 1996 and 2014. An analysis was made of the epidemiological, clinical, microbiological and echocardiographic data, complications during hospital admission, need for surgery, in-hospital mortality, and 1-year follow-up. Cases with endocarditis on prosthetic valves or other locations were excluded, as well as those for which the aortic valve morphology had not been accurately defined. A comparative statistical analysis was performed between BAV and tricuspid (TAV). RESULTS: Of a total of 328 cases with IE, 118 (35.67%) were on aortic valve, with 18 (16.22%) of them being BAV. The BAV cases were younger than TAV (51±19.06 vs. 60.83±15.73 years, P=.021) and they had less comorbidity (Charlson 0.67±0.77 vs. 1.44±1.64, P=.03).). There was a higher tendency of Staphylococcal origin (38.9 vs. 21.5%, P=.137), and 55.6% showed peri-valvular complications (TAV 16.1%, P=.001), in particular, abscesses (38.9 vs.16.1%, P=.047). BAV was the only predictive factor of peri-valvular complications (OR 7.87, 95% CI; 2.38-26.64, P=.001). Patients with BAV had more surgery during their admission (83.3 vs. 44.1%, P=.004), had less in-hospital mortality, with no statistical significance (5.6 vs. 25.8%, P=.069), and 1-year survival was significantly superior (93.8 vs 69.3%, P=.048). CONCLUSIONS: Patients with IE on BAV are young, with low comorbidity. They frequently present with peri-valvular complications and they often require early surgery. Compared to TAV cases, in-hospital mortality is lower and 1-year survival is significantly higher.

Neurological complications of infective endocarditis: risk factors, outcome, and impact of cardiac surgery: a multicenter observational study.

BACKGROUND: The purpose of this study was to assess the incidence of neurological complications in patients with infective endocarditis, the risk factors for their development, their influence on the clinical outcome, and the impact of cardiac surgery. METHODS AND RESULTS: This was a retrospective analysis of prospectively collected data on a multicenter cohort of 1345 consecutive episodes of left-sided infective endocarditis from 8 centers in Spain. Cox regression models were developed to analyze variables predictive of neurological complications and associated mortality. Three hundred forty patients (25%) experienced such complications: 192 patients (14%) had ischemic events, 86 (6%) had encephalopathy/meningitis, 60 (4%) had hemorrhages, and 2 (1%) had brain abscesses. Independent risk factors associated with all neurological complications were vegetation size ≥3 cm (hazard ratio [HR] 1.91), Staphylococcus aureus as a cause (HR 2.47), mitral valve involvement (HR 1.29), and anticoagulant therapy (HR 1.31). This last variable was particularly related to a greater incidence of hemorrhagic events (HR 2.71). Overall mortality was 30%, and neurological complications had a negative impact on outcome (45% of deaths versus 24% in patients without these complications; P<0.01), although only moderate to severe ischemic stroke (HR 1.63) and brain hemorrhage (HR 1.73) were significantly associated with a poorer prognosis. Antimicrobial treatment reduced (by 33% to 75%) the risk of neurological complications. In patients with hemorrhage, mortality was higher when surgery was performed within 4 weeks of the hemorrhagic event (75% versus 40% in later surgery). CONCLUSIONS: Moderate to severe ischemic stroke and brain hemorrhage were found to have a significant negative impact on the outcome of infective endocarditis. Early appropriate antimicrobial treatment is critical, and transitory discontinuation of anticoagulant therapy should be considered.

MYC targeting by OMO-103 in solid tumors: a phase 1 trial.

Among the 'most wanted' targets in cancer therapy is the oncogene MYC, which coordinates key transcriptional programs in tumor development and maintenance. It has, however, long been considered undruggable. OMO-103 is a MYC inhibitor consisting of a 91-amino acid miniprotein. Here we present results from a phase 1 study of OMO-103 in advanced solid tumors, established to examine safety and tolerability as primary outcomes and pharmacokinetics, recommended phase 2 dose and preliminary signs of activity as secondary ones. A classical 3 + 3 design was used for dose escalation of weekly intravenous, single-agent OMO-103 administration in 21-day cycles, encompassing six dose levels (DLs). A total of 22 patients were enrolled, with treatment maintained until disease progression. The most common adverse events were grade 1 infusion-related reactions, occurring in ten patients. One dose-limiting toxicity occurred at DL5. Pharmacokinetics showed nonlinearity, with tissue saturation signs at DL5 and a terminal half-life in serum of 40 h. Of the 19 patients evaluable for response, 12 reached the predefined 9-week time point for assessment of drug antitumor activity, eight of those showing stable disease by computed tomography. One patient defined as stable disease by response evaluation criteria in solid tumors showed a 49% reduction in total tumor volume at best response. Transcriptomic analysis supported target engagement in tumor biopsies. In addition, we identified soluble factors that are potential pharmacodynamic and predictive response markers. Based on all these data, the recommended phase 2 dose was determined as DL5 (6.48 mg kg-1).ClinicalTrials.gov identifier: NCT04808362 .

Liver toxicity associated with antiretroviral therapy including efavirenz or ritonavir-boosted protease inhibitors in a cohort of HIV/hepatitis C virus co-infected patients.

OBJECTIVES: To compare the frequency of grade 3 or 4 transaminase elevations (TEs) in HIV/hepatitis C virus (HCV) co-infected patients who started a three-antiretroviral drug regimen including efavirenz or a ritonavir-boosted protease inhibitor (PI/r) and the influence of pre-existing significant hepatic fibrosis or cirrhosis. PATIENTS AND METHODS: All pre-treated or treatment-naive HIV/HCV co-infected patients who started an antiretroviral regimen including two nucleos(t)ide reverse transcriptase inhibitors along with efavirenz or a PI/r in seven Spanish centres from January 2007 to December 2009 were included in this prospective study. RESULTS: Of 262 patients included in this study, 76 (29%) individuals began antiretroviral therapy (ART) including efavirenz and 186 (71%) a PI/r-based combination. The median (interquartile) follow-up was 14.0 (6.2-23.7) months. A total of 20 (7.6%) patients presented grade 3-4 TEs. Four (1.5%) subjects discontinued ART due to this adverse event. Grade 3-4 TEs were observed in 5 (6.6%) subjects receiving efavirenz and 15 (8.1%) treated with PI/r (P = 0.681). Three (6.5%) patients in the efavirenz group with significant fibrosis developed grade 3-4 TEs versus 2 (8.7%) without pre-existing significant fibrosis (P = 0.743). In the PI/r group, the corresponding figures were 10 (8.8%) and 5 (9.3%), respectively (P = 0.931). CONCLUSIONS: The frequency of grade 3-4 TEs associated with efavirenz-based ART combinations under clinical practice conditions is low and similar to that found in patients receiving PI/r currently used in HIV/HCV co-infected patients. The baseline fibrosis stage does not have an impact on the development of TEs caused by these antiretroviral drugs in this population.

Evaluation of changes in intestinal microbiota in Crohn's disease patients after anti-TNF alpha treatment.

Intestinal dysbiosis is key in the onset and development of Crohn's disease (CD). We evaluated the microbiota changes in CD patients before and after a six-month anti-TNF treatment, comparing these changes with the microbiota of healthy subjects. This prospective multicenter observational study involved 27 CD patients initiating anti-TNF treatment and 16 healthy individuals. Inflammatory activity was determined at baseline, 3 and 6 months, classifying patients into responders and non-responders. Fecal microbiota was analyzed by massive genomic sequencing thought 16S rRNA amplicon sequencing before and after six months of anti-TNF treatment. The CD cohort showed a decrease in genera of the class Clostridia, short-chain fatty acid producers, and an increase in the phylum Proteobacteria (p < 0.01) versus the healthy cohort. After anti-TNF treatment, the phylum Proteobacteria also increased in non-responders versus responders (13/27) (p < 0.005), with the class Clostridia increasing. In addition, alpha diversity increased in responders versus non-responders (p < 0.01), tending towards eubiosis. An association was found (p < 0.001) in the F.prausnitzii/E.coli ratio between responders and non-responders. The F/E ratio was the most accurate biomarker of anti-TNF response (area under the curve 0.87). Thus, anti-TNF treatment allows partial restoration of intestinal microbiota in responders and the F.prausnitzii/E.coli ratio can provide a reliable indicator of response to anti-TNF in CD.

Evaluation of Changes in Gut Microbiota in Patients with Crohn's Disease after Anti-Tnfα Treatment: Prospective Multicenter Observational Study.

Background: Crohn's disease is believed to result from the interaction between genetic susceptibility, environmental factors and gut microbiota, leading to an aberrant immune response. The objectives of this study are to evaluate the qualitative and quantitative changes in the microbiota of patients with Crohn's disease after six months of anti-tumor-necrosis factor (anti-TNFα) (infliximab or adalimumab) treatment and to determine whether these changes lead to the recovery of normal microbiota when compared to a control group of healthy subjects. In addition, we will evaluate the potential role of the Faecalibacterium prausnitzii/Escherichia coli and Faecalibacterium prausnitzii/Clostridium coccoides ratios as indicators of therapeutic response to anti-TNFα drugs. Methods/Design: This prospective multicenter observational study will comprise a total of 88 subjects: 44 patients with Crohn's disease scheduled to start anti-TNFα treatment as described in the drug specifications to control the disease and 44 healthy individuals who share the same lifestyle and eating habits. The presence of inflammatory activity will be determined by the Harvey-Bradshaw index, analytical parameters in blood, including C-reactive protein, and fecal calprotectin levels at commencement of the study, at three months and at six months, allowing the classification of patients into responders and non-responders. Microbiota composition and the quantitative relationship between Faecalibacterium prausnitzii and Escherichia coli and between Faecalibacterium prausnitzii and Clostridium coccoidesgroup as indicators of dysbiosis will be studied at inclusion and six months after initiation of treatment using ultra sequencing with Illumina technology and comparative bioinformatics analysis for the former relationship, and digital droplet PCR using stool samples for the latter. Upon inclusion, patients will complete a survey of dietary intake for the three days prior to stool collection, which will be repeated six months later in a second collection to minimize dietary bias. Discussion: In this study, massive sequencing, a reliable new tool, will be applied to identify early biomarkers of response to anti-TNF treatment in patients with Crohn's disease to improve clinical management of these patients, reduce morbidity rates and improve efficiency.

Natural history of compensated hepatitis C virus-related cirrhosis in HIV-infected patients.

OBJECTIVE: To provide information about the incidence and predictors of liver decompensation and death due to liver failure in human immunodeficiency virus (HIV)-infected patients with compensated hepatitis C virus (HCV)-related cirrhosis. METHODS: Prospective cohort study of 154 HIV-HCV-coinfected patients with a new diagnosis of Child-Pugh-Turcotte (CPT) class A compensated cirrhosis. We evaluated time from diagnosis to the first liver decompensation and death from liver disease, as well as predictors of these outcomes. RESULTS: Thirty-six patients (23.4%) developed liver decompensation. The incidence of liver decompensation was 6.40 cases per 100 person-years (95% confidence interval [CI], 4.18-9.38 cases per 100 person-years). Factors independently associated with liver decompensation were lack of HCV therapy (hazard ratio [HR], 3.38; 95% CI, 1.09-10.53; P = .035), baseline CD4 cell counts

Insulin resistance is not a relevant predictor of sustained virological response to pegylated interferon plus ribavirin in HIV/HCV co-infected patients.

BACKGROUND/AIMS: To evaluate the possible influence of baseline insulin resistance in sustained virological response. METHODS: One hundred and fifty-five consecutive individuals from a multicentric cohort of HIV/HCV co-infected patients who underwent therapy with pegylated interferon plus ribavirin were included. The main outcome variable was sustained virological response, defined as undetectable plasma HCV RNA at week 24 after the end of the therapy. Insulin resistance was determined using the HOMA method. RESULTS: Sustained virological response was achieved in 55 (36%) patients. Forty-two (38%) patients with a HOMA lower than 4 developed sustained virological response vs 13 (29%) of those with a HOMA above 4 (p=0.27). Analyses restricted to patients harbouring genotype 1 or 4 showed similar rates of sustained virological response among patients with a HOMA below and above 4 [19 (27%) vs 7 (24%); p=0.8]. In the multivariate analysis, genotype 3 [AOR 9.26; 95% CI 3.03-28.30; p<0.0001], a baseline HCV viral load below 600.000IU/mL [AOR 2.97; 95% CI 1.03-8.57; p=0.04] and baseline LDL cholesterol above 100mg/dL [AOR 6.62; 95% CI 1.97-22.19; p=0.002] were independently associated with sustained virological response. CONCLUSIONS: Insulin resistance is not a relevant predictor of sustained virological response to pegylated interferon plus ribavirin in HIV/HCV co-infected patients.

Left endocarditis, changes in the new millennium. / Endocarditis infecciosas izquierdas, cambios con el nuevo milenio.

INTRODUCTION: a description of infective left endocarditis at the turn of the millennium. METHOD: A multicentre prospective study into the left endocarditis using data collected from the Andalusian cohort for the study of cardiovascular infections during 1984-2014. RESULTS: Of the 1,604 endocarditis cases collected, 382 belonged to G1 (group-1, period 1983-1999) and 1,222 to G2 (group-2, 2000-2014). Patients in the new millennium have a significantly higher mean age, have more comorbidity and concomitant diseases, and nosocomial and health-related endocarditis are more frequent, as well as complications. An increase in methicillin-resistant Staphylococcus aureus, Enterococcus sp., Gram-negative bacilli and Streptococcus bovis was noted. Regarding treatment, there is an increase in the use of cephalosporins and a decrease in penicillins; there is more surgery when admitted to hospital and less delay. Mortality stands at around 30% in both millennia. In the multivariate analysis, mortality was associated with: previous millennium (G1), age, Charlson index, renal failure and septic shock, and aetiologically with Staphylococcus aureus. CONCLUSIONS: Mortality remains stable, despite diagnostic and therapeutic improvements, because patients are older, have greater comorbidity, a closer relationship with the health care system (nosocomial) and microorganisms are more aggressive.

Role of age and comorbidities in mortality of patients with infective endocarditis.

PURPOSE: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. METHODS: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. RESULTS: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32-3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39-1.88),and non-performed surgery (HR:1.64;95% CI:11.16-1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. CONCLUSION: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group.

[Transversal laryngotomy. Oncologic and functional results in laryngeal sarcoma. (Malignant fibrous histiocytoma). Case report and literature review]. / Presentación de un caso de sarcoma maligno laríngeo, tratado mediante laringotomía transversa y revisión de la literatura.

Sarcomas of the larynx are rare neoplasmas that consitute less than 1% of laryngeal malignancies, and their usual treatment is surgery including partial and total laryngectomy and endoscopic laser cordotomy with reported 20% recurrence. Due to previous positive experience from transversal laryngotomy in patients who underwent aritenoidectomy to treat bilateral cord paralysis after total thyroidectomy, the purpose of this work was to report on the surgical treatment of this rare case with such technique. Thus, a 47 year-old physician who complained of hoarseness for four months without dyspnea, stridor, or dysphagia and with no history of irradiation or chemotherapy was operated after both endoscopic and tomographic studies showed a 3 to 4 cm glotic tumor in its right side, with no ulceration. The pathology proved to be malignant fibrous histiocytoma. Five years after surgery the patient is alive with no evidence of disease.

Aetiology of renal failure in patients with infective endocarditis. The role of antibiotics. / Etiología de la insuficiencia renal en pacientes con endocarditis infecciosa. Papel de los antibióticos.

BACKGROUND AND OBJECTIVES: The possible renal toxicity of certain antibiotics (AB) is well known. The objective of our work is to know the possible effect of AB treatments in the development of renal failure (RF) in patients with infective endocarditis (IE). MATERIAL AND METHOD: Collection from a national multi-centre registry of collection on renal function, both prior and its impairment, if any, during the treatment of IE and in relation to possible causative factors, including the use of AB. RESULTS: Between 2008 and 2012, 1,853 episodes of IE reported from 26 Spanish centres were analysed. Of these, 21.6% had prior RF. They developed new RF or impairment of renal function in 38.7% of the cases. In patients with prior RF, impairment was more frequent (64 vs. 31.7%, P<.001). Overall, patients with RF were older (70.6 vs. 67 years, P<.01), had more comorbidities (Charlson index 5 vs. 4, P<.01), and IE by Staphylococcus aureus (32.1 vs. 16.5%, P<.01). Potentially nephrotoxic AB use was only associated with RF in patients without prior RF (aminoglycosides: OR=1.47 [95% CI 1.096-1.988], P=.010; aminoglycosides with vancomycin: OR=1.49 [95% CI 1.069-2.09], P=.019). CONCLUSIONS: In patients without prior RF, the use of nephrotoxic AB is associated with impairment of renal function. In patients with RF prior to the IE episode, impairment of renal function was more frequent but appears to be more related to the severity of infection.

Survival and prognostic factors of HIV-infected patients with HCV-related end-stage liver disease.

OBJECTIVE: To find the survival and the predictors of death of HIV-infected patients with hepatitis C virus (HCV)-related end-stage liver disease (ESLD). DESIGN AND METHODS: A prospective cohort study set in the infectious diseases units of four tertiary care public hospitals in Andalucía, Spain. From a multicentric cohort of 2664 HIV/HCV-co-infected patients, all consecutive patients with HCV-related cirrhosis who presented with the first hepatic decompensation from January 1997 to June 2004 were followed-up and 153 patients were included. The survival and the demographic, HIV-related and liver-related factors associated with death were evaluated. RESULTS: Ninety-five (62%) patients died during the follow-up. In 79 (85%) individuals, the cause of death was liver related. The median survival time was 13 months. Independent predictors of survival were Child score [hazard ratio (HR), 1.2; 95% confidence interval (CI), 1.08-1.37; P = 0.001], CD4+ cell count at decompensation lower than 100 cells/microl (HR, 2.48; 95% CI, 1.52-4.06; P < 0.001) and hepatic encephalopathy as the first hepatic decompensation (HR, 2.45; 95% CI, 1.41-4.27; P = 0.001). HAART was prescribed to 101 (66%) patients. The cumulative probability of survival in patients under HAART was 60% at 1 year and 40% at 3 years, versus 38 and 18%, respectively, in patients not treated with HAART (P < 0.0001). The HR (95% CI) of death in patients on HAART was 0.5 (0.3-0.9), (P = 0.03). CONCLUSIONS The survival of HIV/HCV-co-infected patients with ESLD is extremely poor. Immunosuppression and markers of severe liver disease predict liver-related mortality in these patients. HAART seems to be associated with a reduced liver-related mortality.

Twelve-Month Estrogen Levels in Premenopausal Women With Hormone Receptor-Positive Breast Cancer Receiving Adjuvant Triptorelin Plus Exemestane or Tamoxifen in the Suppression of Ovarian Function Trial (SOFT): The SOFT-EST Substudy.

PURPOSE: To describe estradiol (E2), estrone (E1), and estrone sulfate (E1S) levels during the first year of monthly triptorelin plus exemestane or tamoxifen and to assess possible suboptimal suppression while receiving exemestane plus triptorelin. PATIENTS AND METHODS: Premenopausal patients with early breast cancer on the Suppression of Ovarian Function Trial who selected triptorelin as the ovarian suppression method and were randomly assigned to exemestane plus triptorelin or tamoxifen plus triptorelin were enrolled until the target population of 120 patients was reached. Blood sampling time points were 0, 3, 6, 12, 18, 24, 36, and 48 months. Serum estrogens were measured with a highly sensitive and specific assay. This preplanned 12-month analysis evaluated E2, E1, E1S, follicle-stimulating hormone, and luteinizing hormone levels in all patients and the proportion of patients with E2 levels greater than 2.72 pg/mL at any time point during treatment with exemestane plus triptorelin. RESULTS: One hundred sixteen patients (exemestane, n = 86; tamoxifen, n = 30; median age, 44 years; median E2, 51 pg/mL; 55% prior chemotherapy) started triptorelin and had one or more samples drawn. With exemestane plus triptorelin, median reductions from baseline E2, E1, and E1S levels were consistently ≥ 95%, resulting in significantly lower levels than with tamoxifen plus triptorelin at all time points. Among patients on exemestane plus triptorelin, 25%, 24%, and 17% had an E2 level greater than 2.72 pg/mL at 3, 6, and 12 months, respectively. Baseline factors related to on-treatment E2 level greater than 2.72 pg/mL were no prior chemotherapy (P = .06), higher body mass index (P = .05), and lower follicle-stimulating hormone and luteinizing hormone (each P < .01). CONCLUSION: During the first year, most patients on exemestane plus triptorelin had E2 levels below the defined threshold of 2.72 pg/mL, consistent with levels reported in postmenopausal patients on aromatase inhibitors, but at each time point, at least 17% of patients had levels greater than the threshold.

Liver Toxicity of Current Antiretroviral Regimens in HIV-Infected Patients with Chronic Viral Hepatitis in a Real-Life Setting: The HEPAVIR SEG-HEP Cohort.

OBJECTIVE: To assess the current frequency of ART-associated grade 3-4 transaminase elevations (TE) and grade 4 total bilirubin elevations (TBE) in HIV-infected patients with chronic hepatitis B and/or C, who start a new regimen of ART. PATIENTS AND METHODS: A total of 192 pre-treated or treatment-naive HIV infected patients with HBV and/or HCV-coinfection who started ART in eight Southern Spanish centers from July/2011-December/2013, were followed for 12 months in this prospective study. RESULTS: Forty-one (21.4%) subjects had been naïve to ART, median (IQR) follow-up was 11.6 (5.6-12.9) months. The most frequently initiated NRTI were tenofovir/emtricitabine [49 patients (25.5%)]. Eighty-nine (46.4%) patients started a ritonavir-boosted protease inhibitor and 77 (40.1%) individuals a NNRTI. Raltegravir and maraviroc were initiated in 24 (12.5%) and 9 (4.7%) individuals. Ten [5.21%; 95% confidence interval (CI): 2.53%-9.37%] patients presented grade 3 TE, while 8 (4.17%; 95%CI: 1.82%-8.04%) subjects showed grade 4 TBE. No episodes of grade 4 TE or ART discontinuation due to hepatotoxic events were observed. The use of ritonavir-boosted atazanavir was the only independent predictor for grade 4 TBE [adjusted odds ratio: 7.327 (95%CI: 1.417-37.89); p = 0.018] in an analysis adjusted for age, sex and baseline HIV-RNA levels, while no factor could be independently associated with grade 3-4 TE. CONCLUSIONS: Currently, the frequency of severe ART-associated TE and TBE under real-life conditions in patients with chronic viral hepatitis is similar to what has been reported previously. However, episodes of grade 4 TE are less frequent and severe TE appears to be of lesser concern.

Incidence and clinical impact of infective endocarditis after transcatheter aortic valve implantation.

AIMS: To describe the characteristics of infective endocarditis (IE) after transcatheter aortic valve implantation (TAVI). METHODS AND RESULTS: This study was performed using the GAMES database, a national prospective registry of consecutive patients with IE in 26 Spanish hospitals. Of the 739 cases of IE diagnosed during the study, 1.3% were post-TAVI IE, and these 10 cases, contributed by five centres, represented 1.1% of the 952 TAVIs performed. Mean age was 80 years. All valves were implanted transfemorally. IE appeared a median of 139 days after implantation. The mean age-adjusted Charlson comorbidity index was 5.45. Chronic kidney disease was frequent (five patients), as were atrial fibrillation (five patients), chronic obstructive pulmonary disease (four patients), and ischaemic heart disease (four patients). Six patients presented aortic valve involvement, and four only mitral valve involvement; the latter group had a higher percentage of prosthetic mitral valves (0% vs. 50%). Vegetations were found in seven cases, and four presented embolism. One patient underwent surgery. Five patients died during follow-up: two of these patients died during the admission in which the valve was implanted. CONCLUSIONS: IE is a rare but severe complication after TAVI which affects about 1% of patients and entails a relatively high mortality rate. IE occurred during the first year in nine of the 10 patients.

Hepatic Safety of Rilpivirine/Emtricitabine/Tenofovir Disoproxil Fumarate Fixed-Dose Single-Tablet Regimen in HIV-Infected Patients with Active Hepatitis C Virus Infection: The hEPAtic Study.

OBJECTIVES: The aim of this study was to evaluate the frequency of transaminase elevations (TE) and total bilirubin elevations (TBE) during the first year of therapy with a single tablet regimen including RPV/FTC/TDF (EPA) in HIV/hepatitis C virus (HCV)-coinfected subjects in clinical practice. METHODS: In a retrospective analysis, HIV/HCV-coinfected subjects who started EPA at 17 centres throughout Spain were included as cases. Subjects who started an antiretroviral therapy (ART) other than EPA during the study period at the same hospitals were randomly selected as controls in a 1:2 ratio. Primary outcome variables were grade (G) 3-4 TE and G4 TBE. RESULTS: Of the 519 subjects included, 173 individuals started EPA. Nine (5.2%) subjects of the EPA group and 49 (14.2%) controls were naïve to ART. The median (Q1-Q3) follow-up was 11.2 (9.7-13.9) months. TE was observed in 2 [1.2%; 95% confidence interval (CI): 0.14%-4.1%] subjects receiving EPA and 11 (3.2%; 95%CI: 1.6%-5.6%) controls (p = 0.136), all events were G3. No patient discontinued ART due to TE. One (0.6%; 95%CI: 0.01%-3.1%) subject on EPA and 8 (2.3%; 95%CI: 1%-4.5%) subjects in the control group developed TBE (p = 0.141), without developing any other hepatic event during follow-up. Three (2.3%) subjects with cirrhosis versus 10 (3.1%) without cirrhosis showed G3-4 TE (p = 0.451). CONCLUSION: The frequency of severe liver toxicity in HIV/HCV-coinfected subjects receiving EPA under real-life conditions is very low, TE were generally mild and did not lead to drug discontinuation. All these data suggest that EPA can be safely used in this particular subpopulation.

Endocarditis in patients with ascending aortic prosthetic graft: a case series from a national multicentre registry.

OBJECTIVES: Endocarditis in patients with ascending aortic prosthetic graft (AAPG) is a life-threatening complication. The purpose of this study was to examine the clinical presentation and prognosis of patients with AAPG endocarditis included in a large prospective infectious endocarditis multicentre study. METHODS: From January 2008 to April 2015, 3200 consecutive patients with infectious endocarditis according to the modified Duke criteria, were prospectively included in the 'Spanish Collaboration on Endocarditis Registry (GAMES)' registry. Twenty-seven definite episodes of endocarditis (0.8%) occurred in patients with AAPG. RESULTS: During the study period, 27 cases of endocarditis were detected in patients with AAPG. The median age of patients was 61 years [interquartile range (IQR) 51-68 years] and 23 (85.2%) patients were male. The median time from AAPG surgery to the episode of AAPG infection was 24 months (IQR 6-108 months). The most frequently isolated micro-organisms were coagulase-negative staphylococci and S. aureus (11 patients, 40.7%). Four patients (14.8%) underwent medical treatment, whereas surgery was performed in 21 (77.7%). Two patients (7.4%) died before surgery could be performed. The median hospital stay prior to surgery was 7 days (IQR 4-21 days). Surgery consisted of replacing previous grafts with a composite aortic graft (10 cases) or aortic homograft (2 patients), and removal of a large vegetation attached to the valve of a composite tube (1 case). Nine patients had an infected aortic valve prosthesis without evidence of involvement of the AAPG. Isolated redo-aortic valve replacement was performed in 8 (88.9%) of these patients. Reinfection occurring during 1 year of follow-up was not detected in any patient. Two patients (7.4%) died while awaiting surgery and 6 did so after surgery (22.2%). A New York Heart Association (NYHA) Class IV was associated with mortality in patients undergoing surgery (P < 0.019). CONCLUSIONS: Most cases of endocarditis in patients with AAPG occur late after initial surgery. Mortality rate of patients with AAPG endocarditis who undergo surgery is acceptable. NYHA Class IV before surgery is associated with an increased postoperative mortality.
