Influence of Thymopentin on Antibody Response, and Monocyte and T Cell Function in Hemodialysis Patients Who Fail to Respond to Hepatitis B Vaccinati…
1990
We investigated the influence of thymopentin as an adjuvant for hepatitis B vaccination on in vitro monocyte and T cell function and in vivo antibody response in a prospective, placebo-controlled double-blind trial in 20 low- and nonresponders to hepatitis B vaccination on chronic hemodialysis. 50 mg thymopentin was given subcutaneously twice per week for 3 weeks, followed by 1 intramuscular injection of 40 micrograms HB-Vax and 3 subsequent injections of thymopentin. After 1 month, the patients were boostered with 40 micrograms HB-Vax. There was no significant difference in T cell and monocyte function after administration of thymopentin, as determined in vitro. After 3 months, 3 patients …
Regional distribution of opioidergic nerves in human and canine prostates
1989
The regional distribution of opioidergic nerves in the juvenile and adult human prostate and in the adult canine prostate has been studied immunohistochemically using well-characterized polyclonal antisera against multiple opioid peptides. Nerves displaying immunoreactivity (ir) for the proenkephalin (PRO-ENK) derivatives met-enkephalin (ME), leuenkephalin (LE), octapeptide, and heptapeptide (ordered in decreasing frequency) were present in the dorsolateral stroma of human prostate. In canine prostate, the situation was similar, but the number of opioid-ir nerve fibers was lower than in human prostate. In both species, staining for the prodynorphin (PRO-DYN) derivatives dynorphin A and alph…
Utility of presepsin (sCD14-ST) as a diagnostic and prognostic marker of sepsis in the emergency department
2015
Presepsin (PSEP) is released during infectious diseases and can be detected in the blood. PSEP has shown promising results as sepsis marker. We examined the diagnostic and prognostic validity of PSEP in patients suspicious of sepsis on admission in the emergency department (ED). Methods One hundred twenty three patients with signs of SIRS and/or sepsis and 123 healthy individuals were enrolled. PSEP was determined on admission, after 8, 24 and 72 h. Results Mean PSEP concentrations of the control group and the patient group were 130 and 1945 pg/ml. PSEP differed between SIRS, sepsis, severe sepsis and septic shock and showed strong association with 30-day mortality ranging from 10.3% in the…
Combined evaluation of resting IGF-I, N-terminal propeptide of type III procollagen (PIIINP) and C-terminal cross-linked telopeptide of type I collag…
2004
To verify whether combined measurements of GH-dependent parameters might be useful in detecting exogenous recombinant GH (rGH) administration in male athletes from different disciplines.Sixty-six athletes (control group) were sampled for the evaluation of resting IGF-I, N-terminal propeptide of type III procollagen (PIIINP) and telopeptide type I collagen (ICTP). Cut-off values (mean + 2 SD) for IGF-I, PIIINP and ICTP were calculated and arbitrary scores (1.5, 2.0) were assigned to abnormal parameters. By using the sum of individual parameter scores, positive (or = 3) or negative (3) scores were obtained. In addition, a subgroup of six athletes was treated for 3 weeks with rGH (0.09 IU/kg b…
Refined atrial fibrillation screening and cost-effectiveness in the German population
2021
ObjectiveLittle is known on optimal screening population for detecting new atrial fibrillation (AF) in the community. We describe characteristics and estimate cost-effectiveness for a single timepoint electrocardiographic screening.MethodsWe performed a 12-lead ECG in the German population-based Gutenberg Health Study between 2007 and 2012 (n=15 010), mean age 55±11 years, 51% men and collected more than 120 clinical and biomarker variables, including N-terminal pro B-type natriuretic peptide (Nt-proBNP), risk factors, disease symptoms and echocardiographic variables.ResultsOf 15 010 individuals, 466 (3.1%) had AF. New AF was found in 32 individuals, 0.2% of the total sample, 0.5% of indivi…
A multiple biomarker risk score for guiding clinical decisions using a decision curve approach.
2011
Aims: We assessed whether a cardiovascular risk model based on classic risk factors (e.g. cholesterol, blood pressure) could refine disease prediction if it included novel biomarkers (C-reactive protein, N-terminal pro-B-type natriuretic peptide, troponin I) using a decision curve approach which can incorporate clinical consequences. Methods and results: We evaluated whether a model including biomarkers and classic risk factors could improve prediction of 10 year risk of cardiovascular disease (CVD; chronic heart disease and ischaemic stroke) against a classic risk factor model using a decision curve approach in two prospective MORGAM cohorts. This included 7739 men and women with 457 CVD …
The effects of amino acid supplementation on hormonal responses to resistance training overreaching.
2005
The purpose of this investigation was to examine the effects of amino acid supplementation on muscular performance and resting hormone concentrations during resistance training overreaching. Seventeen resistance-trained men were randomly assigned to either an amino acid (AA) or a placebo (P) group and underwent 4 weeks of total-body resistance training designed to induce a state of overreaching. The protocol consisted of two 2-week phases (phase 1, 3 sets of 8 exercises performed for 8-12 repetitions; phase 2, 5 sets of 5 exercises performed for 3-5 repetitions). Muscle strength and resting blood samples were determined before (T1) and at the end of each training week (T2-T5). One-repetitio…
Biomarkers for characterization of heart failure - Distinction of heart failure with preserved and reduced ejection fraction.
2016
Heart failure (HF) incidence is rising worldwide and HF with preserved ejection fraction (HFpEF) represents nearly half of all cases. Treatment options are still limited in HFpEF in comparison to HF with reduced ejection fraction (HFrEF).We analyzed biomarkers in the general population to characterize HFpEF and HFrEF and defined a biomarker index to differentiate HFpEF from HFrEF. Growth differentiation factor-15 (GDF-15), soluble source of tumorigenicity 2 (sST2), C-reactive protein (CRP) and NT-proBNP were measured in 5000 individuals of the population-based Gutenberg Health Study (GHS). The median follow-up time for all-cause mortality was 7.3years with 213 events.Identification of subje…
Association of MR-proadrenomedullin with cardiovascular risk factors and subclinical cardiovascular disease.
2012
Abstract Aims and background Midregional proadrenomedullin (MR-proADM) is a protein, which exerts various effects on the cardiovascular system. Recent studies underscored its prognostic implications in patients with acute dyspnea and cardiovascular diseases. Therefore, we aimed to determine the distribution of MR-proADM in the general population and to reveal potential associations of MR-proADM with cardiovascular risk factors and measures of subclinical cardiovascular disease. Methods and results MR-proADM plasma concentrations were determined in individuals of the population-based cohort of the Gutenberg Health Study ( N = 5000) using a commercially available fluoroimmunoassay. Individua…
