Effect of Intravenous IgM-Enriched Immunoglobulins on Presepsin and Other Sepsis Biomarkers
2021
Patients in septic shock with low IgG and IgM serum concentrations have higher mortality rates compared to those with normal immunoglobulin levels and, therefore, there is a rational explanation to administer intravenous IgM-enriched immunoglobulins to septic patients in ICU. Aim of this study is to evaluate the effectiveness of intravenous IgM-enriched immunoglobulins in decreasing several sepsis biomarker concentrations. 26 sepsis patients were enrolled in this observational cohort study and Nitric Oxide, Endocan, Pentraxin and presepsin serum levels were measured during their first 3 days of ICU stay. The use of intravenous IgM-enriched immunoglobulins did not influence the temporal evol…
Crystalline subtype of pre-descemetic corneal dystrophy.
2014
Purpose: To report corneal findings in a familial case of the crystalline subtype of pre- Descemetic corneal dystrophy. Case Report: A 19-year-old girl and her 44-year-old mother were found to have asymptomatic, bilateral, punctiform and multi-colored crystalline opacities across the whole posterior layer of the corneas. Endothelial specular microscopy revealed the presence of white round flecks located at different levels anterior to the endothelium. No systemic abnormalities or medications could be related to account for these findings. Conclusion: To the best of our knowledge, this is the third familial report of this rare corneal disorder. Differential diagnosis may include Schnyder cor…
Plasma levels of inflammatory and thrombotic/fibrinolytic markers in acute ischemic strokes: Relationship with TOAST subtype, outcome and infarct site
2009
BACKGROUND: The aim of our study was to evaluate in patients with acute ischemic stroke the relationship between immuno-inflammatory variables, clinical outcome and infarct site. MATERIALS AND METHODS: We evaluated plasma levels of IL-1beta, TNF-alpha, IL-6 and IL-10, E-selectin, P-selectin, sICAM-1 ,sVCAM-1 vWF, TPA and PAI-1. RESULTS: Patients with cardioembolic subtype showed significantly higher median plasma levels of TNF-alpha, IL-6, IL-1beta whereas the lacunar subtype showed significantly lower median plasma levels of TNF-alpha, IL-6 and IL-1beta. CONCLUSIONS: A significant association was noted between the severity of neurological deficit at admission, the diagnostic subtype and so…
Genetically predicted longer telomere length is associated with increased risk of B-cell lymphoma subtypes
2016
International audience; Evidence from a small number of studies suggests that longer telomere length measured in peripheral leukocytes is associated with an increased risk of non-Hodgkin lymphoma (NHL). However, these studies may be biased by reverse causation, confounded by unmeasured environmental exposures and might miss time points for which prospective telomere measurement would best reveal a relationship between telomere length and NHL risk. We performed an analysis of genetically inferred telomere length and NHL risk in a study of 10 102 NHL cases of the four most common B-cell histologic types and 9562 controls using a genetic risk score (GRS) comprising nine telomere length-associa…
Dynamic clonal remodelling in breast cancer metastases is associated with subtype conversion
2019
Background: Changes in the clinical subtype (CS) and intrinsic subtype (IS) between breast cancer (BC) metastases and corresponding primary tumours have been reported. However, their relationship with tumour genomic changes remains poorly characterised. Here, we analysed the association between genomic remodelling and subtype conversion in paired primary and metastatic BC samples. Methods: A total of 57 paired primary and metastatic tumours from GEICAM/2009-03 (ConvertHER, NCT01377363) study participants with centrally assessed CS (n = 57) and IS (n = 46) were analysed. Targeted capture and next-generation sequencing of 202 genes on formalin-fixed paraffin-embedded samples was performed. Th…
Nieru audzēju klīniski morfoloģiskais raksturojums
2020
Saslimstība ar ļaundabīgajiem nieru audzējiem palielinās katru gadu, visizteiktāk tas vērojams pasaules attīstītajās valstīs, kā arī Latvijā. Nieru šūnu karcinoma ir viens no visbiežākajiem ļaundabīgajiem nieru audzējiem. Agrīnajās stadijās nieru šūnu karcinomai nav raksturīga kāda konkrēta simptomātika un lielākajā daļā gadījumu, tā tiek diagnosticēta netīši- veicot izmeklējumus kādas citas saslimšanas gadījumā. Pēc tam, kad audzējs ir ticis diagnosticēts, ir būtiski izvērtēt pacienta vispārējo stāvokli un riska faktorus, no kā ir atkarīga pacientu kopējā dzīvildze un recidīva risks. Ja iespējams, noteikt histoloģisko nieru šūnu karcinomas subtipu un ņemot vērā šos faktorus, izvēlēties pie…
Dynamics and molecular evolution of HIV-1 strains in Sicily among antiretroviral naïve patients.
2012
Abstract HIV-1 subtype B is the most frequent strain in Sicily. To date, there is no available data about the genetic diversity of HIV-1 viral strains circulating in Sicily among antiretroviral (ARV) naive subjects and the role of immigration as potential determinant of evolutionary dynamics of HIV-1 molecular epidemiology. For this purpose, HIV-1 polymerase (pol) sequences obtained from 155 ARV naive individuals from 2004 to 2009 were phylogenetically analysed. The overall rate of HIV-1 non-B infections was 31.0% (n = 48/155), increasing from 7.8% in 2004–2006 to 40.9% in 2009, and about one-third were identified as unique recombinant forms. CRF02_AG was the prevalent non-B clade (n = 28/4…
Prognosis of hospitalized patients with 2009 H1N1 influenza in Spain: influence of neuraminidase inhibitors
2012
The H1N1 influenza pandemic strain has been associated with a poor prognosis in hospitalized patients. The present report evaluates the factors influencing prognosis.A total of 813 patients hospitalized with H1N1 influenza in 36 hospitals (nationwide) in Spain were analysed. Detailed histories of variables preceding hospital admission were obtained by interview, validating data on medications and vaccine with their attending physicians. Data on treatment and complications during hospital stay were recorded. As definition of poor outcome, the endpoints of death and admission to intensive care were combined; and as a further outcome, length of stay was used.The mean age was 38.5 years (SD 22.…
Muscarinic inhibition of endogenous noradrenaline release from rabbit isolated trachea: receptor subtype and receptor reserve.
1994
The aim of the present study was to characterize putative muscarine receptors on sympathetic nerve terminals in the rabbit trachea. Release of endogenous noradrenaline from in vitro incubated rabbit trachea was evoked by electrical field stimulation (3 Hz, 540 pulses) and quantified by high performance liquid chromatography with electrochemical detection. The muscarine receptor agonist oxotremorine inhibited the evoked release of noradrenaline completely at 1 mumol/l (EC50: 64 nmol/l). The concentration response curve was very steep (Hill coefficient of 2.3). Scopolamine shifted the concentration response curve of oxotremorine to the right (-log KB 8.48) demonstrating specific, inhibitory m…
Evaluation of HIV transmission clusters among natives and foreigners living in Italy
2020
We aimed at evaluating the characteristics of HIV-1 molecular transmission clusters (MTCs) among natives and migrants living in Italy, diagnosed between 1998 and 2018. Phylogenetic analyses were performed on HIV-1 polymerase (pol) sequences to characterise subtypes and identify MTCs, divided into small (SMTCs, 2&ndash
