Cornael microbe infections these days.
The prognosis of myeloid sarcoma (MS) is controversial. Many reports indicated that orbital-MS has a good prognosis and is closely related to t(8;21), but the prognostic role of MS in pediatric t(8;21) AML is unclear. We retrospectively analyzed data from 127 patients with pediatric t(8;21) AML diagnosed between January 2010 and June 2018. We compared patients with (n = 30) and without MS (n = 97). The median follow-up time was 52.6 months. The proportion of t(8;21) AML patients with MS was 23.6%. Males were more likely to have MS than females. The complete remission rate after the first course of induction chemotherapy and the 3-year relapse-free survival (RFS) among patients with MS were lower than those among patients without MS (60% vs. 78.4%, p = 0.045) (68.8 ± 8.8% vs. 88.0 ± 3.4%, p = 0.004). The female sex and a higher level of RUNX1/RUNX1T1 transcripts after consolidation were risk factors for poor RFS among patients with MS. Our data showed that MS was an independent risk factor in pediatric t(8;21) AML. Close monitoring of measurable residual disease of the bone marrow and extramedullary lesions is needed to guide stratified treatment.
The impact of cytomegalovirus infection in elderly subjects remains unclear. This study examined the relationship between humoral immune response to cytomegalovirus (CMV) and all-cause mortality in a cohort of elderly hospitalised patients.

Data were obtained from a random sample of 715 patients (≥65 years old) admitted for any cause in a third level hospital. BrefeldinA Serum IgG antibody against CMV was determined by enzyme-linked immunosorbent (ELISA) assay.

A total of 480 deaths occurred in seropositive patients (
 = 671) during a follow-up of 7.6 years (mean, 4.6); of which 112 patients died in-hospital or within 30 days after discharge (short-term mortality). For patients with CMV IgG antibody levels in the highest quartile compared with lower quartile, fully adjusted models showed that mortality was 1.40 times (95% CI 1.05-1.86) and 2.20 times (95% CI 1.15-4.21) higher, respectively. The exclusion of patients with cardiovascular disease (angina, myocardial infarction, heart failure, peripheral artery disease, or stroke) increases the risk of long-term (HR 2.22, 95% CI 1.36-3.62) and short-term mortality (OR 3.18, 95% CI 1.40-7.24).

Increased IgG antibody levels against CMV are associated with increased short and long-term mortality in elderly hospitalised patients, especially in patients without cardiovascular disease. Key Messages The outcome of elderly hospitalised patients in relation to CMV is unknown. We demonstrate an association between increased anti-CMV IgG levels and mortality. This association is greater in elderly patients without cardiovascular disease.

In this context, the European Immunogenicity Platform annual meeting provides opportunities for experts from industry and academia, regulators and clinicians to convene and discuss immunogenicity assessment methods and tools. This report summarizes the key messages on immunogenicity testing, prediction, clinical relevance and advanced therapy medicinal products discussed at the 11th Open Scientific European Immunogenicity Platform Symposium on Immunogenicity of Biopharmaceuticals, Lisbon, Portugal, 17-19 February 2020.
Despite antifungal prophylaxis, liver transplanted patients are endangered by invasive fungal infections (IFI). Routinely used microbiological procedures are hallmarked by significant weaknesses, which may lead to a delay in antifungal treatment.

Culture-based fungal findings, routinely used biomarkers of infection/inflammation (e.g., procalcitonin or C-reactive protein), as well as corresponding plasma concentrations of soluble Intercellular Adhesion Molecule (ICAM)-1 were analysed in 93 patients during a period of 28 days following liver transplantation (LTX).

Plasmatic sICAM-1 was significantly elevated in patients affected by an IFI within the first 28 days in comparison to fungally colonised or unobtrusive LTX patients. sICAM-1 might therefore be helpful for the identification of IFI patients after LTX (e.g., Receiver Operating Characteristic (ROC)-Area Under the Curve (AUC) 0.714 at 14d after LTX). The diagnostic performance of sICAM-1 was further improved by its combined use with different other IFI biomarkers (e.g., midregional proadrenomedullin).

The diagnostic deficiencies of routinely used microbiological procedures for IFI detection in patients after LTX may be reduced by plasmatic sICAM-1 measurements.

Tenascin-C is a marker of interstitial fibrosis. We assessed whether plasma Tenascin-C differed between heart failure with preserved ejection fraction (HFpEF) and asymptomatic controls and related to clinical outcomes.

Prospective, observational study of 172 age- and sex-matched subjects (HFpEF
 = 130; controls
 = 42, age 73 ± 9, males 50%) who underwent phenotyping with 20 plasma biomarkers, echocardiography, cardiac MRI and 6-minute-walk-testing. The primary endpoint was the composite of all-cause death/HF hospitalisation.

Tenascin-C was higher in HFpEF compared to controls (13.7 [10.8-17.3] vs (11.1 [8.9-12.9] ng/ml,
 < 0.0001). Tenascin-C correlated positively with markers of clinical severity (NYHA, E/E', BNP) and plasma biomarkers reflecting interstitial fibrosis (ST-2, Galectin-3, GDF-15, TIMP-1, TIMP-4, MMP-2, MMP-3, MMP-7, MMP-8), cardiomyocyte stress (BNP, NTpro-ANP), inflammation (MPO, hs-CRP, TNFR-1, IL6) and renal dysfunction (urea, cystatin-C, NGAL);
 < 0.05 for all. During follow-up (median 1428 days), there were 61 composite events (21 deaths, 40 HF hospitalizations).
