Myocarditis is an inflammatory disease of the heart frequently resulting from viral infections and/or post-viral immune-mediated responses. It is one of the important causes of dilated cardiomyopathy worldwide. The diagnosis is presumed on clinical presentation and noninvasive diagnostic methods such as cardiovascular magnetic resonance imaging. Endomyocardial biopsy remains the gold standard for in vivo diagnosis of myocarditis. The therapeutic and prognostic benefits of endomyocardial biopsy results have recently been demonstrated in several clinical trials. Although remarkable advances in diagnosis, understanding of pathophysiological mechanisms, and treatment of acute myocarditis were gained during the last years, no standard treatment strategies could be defined as yet, apart from standard heart failure therapy and physical rest. In severe cases, mechanical support or heart transplantation may become necessary. There is some evidence that immunosuppressive and immunomodulating therapy are effective for chronic, virus-negative inflammatory cardiomyopathy. Further investigations by controlled, randomized studies are needed to definitively determine their role in the treatment of myocarditis.
AimsThe objective of this study was to examine cognitive and psychological processes systematically in patients with decompensated chronic heart failure (CHF) and to document changes in cognitive function after compensation. Executive functions, episodic memory, and attention are impaired in patients with stable CHF, influencing health behaviour and disease management. Cognitive function and psychological co-morbidities are associated with hospitalization, disability, and mortality.
Methods and resultsCognitive performance, self-perceived quality of life, and depression were compared in 20 patients with decompensated CHF [ejection fraction (EF) 27 + 8%, N-terminal pro brain natriuretic peptide (NT-proBNP) 10 880 pg/mL, interquartile range (4495-13 683)] before and after compensation, 20 age-and gender-matched stable CHF patients [New York Heart Assocation (NYHA) III -IV, EF 32 + 10%, NT-proBNP 1881 pg/mL (323 -1502)], and 20 healthy controls (EF 70 + 5%). Patients with decompensated CHF showed significantly poorer performance in terms of short-term memory, working memory, executive control, and processing speed (P , 0.05) compared with stable CHF patients. Compensation improved the cognitive performance of decompensated CHF patients up to the level of patients with stable CHF. Compared with healthy controls, both patient groups were affected with respect to episodic memory (P , 0.0001) and fluid intelligence (P , 0.01).
ConclusionDecompensated heart failure patients are highly impaired in cognitive functioning, which improves but does not normalize after compensation. Neuropsychological diagnostics delivers important details for daily life activities and might identify individuals deserving special care.--
Background: Sublingual immunotherapy (SLIT) allergy vaccines have an excellent safety profile, but opinions vary on their efficacy, and treatment regimens are often lengthy. This study assessed the effects of the Toll-like receptor 4 agonist monophosphoryl lipid A (MPL®) on safety/tolerability and clinical and immunological efficacy when combined with grass pollen SLIT formulations in treating patients with seasonal allergic rhinitis. This is the first reported study of adjuvanted SLIT. Methods: In this double-blind placebo-controlled phase I/IIa study, 80 grass pollen-sensitive subjects were randomized into 4 groups of 20 subjects to receive daily treatment for 8 weeks. Sixteen patients per group received SLIT and 4 received placebo. The formulation given to each group varied with respect to grass pollen extract and MPL content. Grass allergen nasal challenge tests (NCTs) were performed prior to dosing and in weeks 4 and 10. Grass pollen-specific immunoglobulin G (IgG) and IgE antibodies were measured at baseline and prior to dosing in weeks 2, 3, 4, 5 and 10. Results: Local and systemic adverse events were generally comparable for patients who received active treatment and placebo. Patients in the 2 groups given SLIT containing the highest amount of MPL experienced the highest proportion of negative NCTs after 10 weeks (47 and 44%, vs. 20% with placebo). These patients also showed earlier median increases in specific IgG and smaller increases in IgE levels than those receiving other formulations. Conclusions: These results suggest that SLIT preparations containing MPL are well tolerated and alter the immunological response to grass antigens after 3 weeks of exposure, with an associated suppression of nasal challenge responses.
In patients of the REPAIR-AMI trial, established clinical parameters are associated with adverse outcome at 5 years exclusively in the placebo group, whereas the migratory capacity of the administered BMC determines event-free survival in the BMC-treated patients. These data disclose a potency-effect relationship between cell therapy and long-term outcome in patients with AMI.
RD reduces blood pressure during exercise without compromising chronotropic competence in patients with resistant hypertension. Heart rate at rest decreased and heart rate recovery improved after the procedure. (Renal Denervation With Uncontrolled Hypertension; [Symplicity HTN-2]; NCT00888433).
We evaluated heart-focused anxiety in the general population and validated the CAQ. Using percentiles based on a normative sample allows screening for heart-focused anxiety in patients with or without cardiac diseases and the measurement of therapy success after psychotherapeutic or pharmacological intervention.
Circulating Angs are closely related to outcome and severity in CS. Angiopoietin-2 emerged as an independent predictor of 28-day and 1-year mortality in CS. Larger studies are required to define the cut-off and predictive values for Ang-2. Angiopoietins may be prognostic biomarkers for survival in CS and might represent a novel therapeutic target.
Abstract. In the recent past, evidence is increasing indicating the existence of a subpopulation of resistant tumor cells in head and neck squamous cell carcinoma (Hnscc) that cannot be eradicated by established antineoplastic treatments. these cancer stem cells (cscs) have features of somatic stem cells such as selfrenewal, proliferation and differentiation. cD44 + cells in tumors of the head and neck are referred to as cscs of Hnscc. expression profiling of cD44 in 29 HNSCC tumors was performed by fluorescence microscopy. elIsA analysis was performed to detect concentration of soluble cD44 in the peripheral blood of 29 Hnscc patients and 11 healthy controls. expression of cD44 was determined in all Hnscc tissue samples (n=29). In all samples a surface staining pattern was found. the concentration of cD44 in the peripheral blood of HNSCC patients was significantly higher compared to a healthy control group (m Hnscc =13.5±0.5 ng/ ml; m cont =9.3±0.6 ng/ml; p=0.6x10 -12 ). the role of cD44 as a marker for cscs in Hnscc remains to be ascertained. Further experiments might reveal its role as a diagnostic and prognostic factor, and possibly as a therapeutic target.
