Calidad de la farmacoterapia y seguridad de los pacientes en hemodiálisis tratados con estimulantes eritropoyéticos
2008
Objective: To assess an interdisciplinary programme for the improvement of pharmacotherapy quality and patient safety in patients with chronic renal disease who are treated with erythropoiesis-stimulating agents. Method: Observational, longitudinal study. Retrospective analysis (period A) and prospective analysis (period B) following implementation of the programme for haemoglobin values and monthly erythropoiesis- stimulating agent dosage. The proportion of patients with haemoglobin values within the target range (10-5-12.5 g/dl) and those with values above the safety limit (≥ 12.5g/dl) were compared every four months and the average percentage of time with haemoglobin values within the ta…
Immunomodulatory and Hematopoietic Effects of Recombinant Human Interleukin-6 in Patients with Advanced Renal Cell Cancer
1996
Interleukin-6 (IL-6) is a cytokine with pleiotropic biologic activities on B cells, T cells, and hematopoietic progenitors. The present study was undertaken to assess pharmacodynamic effects of subcutaneous administration of IL-6 on blood counts, immunologic parameters, and acute-phase reactants. Blood samples were taken from patients with advanced renal cell cancer participating in a phase II trial of recombinant human IL-6. Multiparameter FACS analyses of peripheral blood mononuclear cells were performed using antibodies against CD3, CD4, CD8, HLA-DR, CD56, CD28, CD38, CD19, sIgM, and sIgG. Serum levels of IL-10, soluble CD23 (sCD23), sCD25, IL-1 receptor antagonist protein (IL-1RA), solu…
Real-Time Polymerase Chain Reaction for Detection of Schistosoma DNA in Small-Volume Urine Samples Reflects Focal Distribution of Urogenital Schistos…
2014
Schistosoma haematobium eggs and Schistosoma DNA levels were measured in urine samples from 708 girls recruited from 18 randomly sampled primary schools in South Africa. Microscopic analysis of two 10-mL urine subsamples collected on three consecutive days confirmed high day-to-day variation; 103 (14.5%) girls had positive results at all six examinations, and at least one positive sample was seen in 225 (31.8%) girls. Schistosoma-specific DNA, which was measured in a 200-μL urine subsample by using real-time polymerase chain reaction, was detected in 180 (25.4%) cases, and levels of DNA corresponded significantly with average urine egg excretion. In concordance with microscopic results, pol…

Association between Serum Heat Shock Proteins and Gamma-Delta T Cells—An Outdated Clue or a New Direction in Searching for an Anticancer Strategy? A …
2021
HSPs demonstrate a strong association with gamma-delta (γδ) T cells. Most of the studies regarding interactions between the parameters were conducted in the 1990s. Despite promising results, the concept of targeting γδ T cells by HSPs seems to be a forgotten direction due to potent non-peptidic phosphoantigens rather than HSPs have been found to be the essential stimulatory components for human γδ cells. Currently, with greater knowledge of lymphocyte diversity, and more accurate diagnostic methods, we decided to study the correlation once again in the neoplastic condition. Twenty-one children with newly diagnosed acute lymphoblastic leukaemia (ALL) were enrolled on the study. Serum HSP90 c…
AN IL-6/IL-6 SOLUBLE RECEPTOR (IL-6R) HYBRID PROTEIN (H-IL-6) INDUCES EPO-INDEPENDENT ERYTHROID DIFFERENTIATION IN HUMAN CD34+CELLS
2000
H-IL-6 is a hybrid protein constructed to contain IL-6 and its soluble receptor linked by a flexible peptide chain. Here we show that H-IL-6 strongly enhances proliferation of human CD34(+)cells in serum-free liquid culture, and that the majority of the cells generated belong to the erythroid lineage, being positive for the marker Glycophorin A. Conversely, H-IL-6 does not increase the number of myeloid, CD13-positive cells. Comparable effects are observed on progenitors from cord blood and adult peripheral blood. Therefore, H-IL-6 triggers an erythroid-inducing signal in haematopoietic progenitor cells, independently from erythropoietin (EPO).
Severe pre-eclampsia is associated with alterations in cytotrophoblasts of the smooth chorion.
2016
Pre-eclampsia (PE), which affects ∼8% of first pregnancies, is associated with faulty placentation. Extravillous cytotrophoblasts (CTBs) fail to differentiate properly, contributing to shallow uterine invasion and deficient spiral artery remodeling. We studied the effects of severe PE (sPE) on the smooth chorion portion of the fetal membranes. The results showed a significant expansion of the CTB layer. The cells displayed enhanced expression of stage-specific antigens that extravillous CTBs normally upregulate as they exit the placenta. Transcriptomics revealed the dysregulated expression of many genes (e.g. placental proteins, markers of oxidative stress). We confirmed an sPE-related incr…
High Resolution CT Angiography in Detection of an Aneurysm of the Vein of Galen as a Source of Intracranial Haemorrhage in a Newborn.
2011
Cerebral haemorrhage is a rare condition in infants and carries a known poor prognosis. Common causes of spontaneous haemorrhage include various vascular venous lesions due to incomplete hydrovenous maturation, among them Galen vein aneurysm may be a very rare cause of cerebral haemorrhage. This report emphasizes the role of multidector CT with high resolution CT angiography in a newborn with cerebral hemorrhage caused by Galen vein aneurysm rupture. MDCT with high resolution CT angiography helps to differentiate the cause of haemorrhage, and to address the appropriate treatment.
Genetic and morphological differentiation ofDikerogammarusinvaders and their invasion history in Central Europe
2002
SUMMARY 1. Biological invasions often involve close taxonomic relatives either as native/invader pairs or as invader/invader pairs. Precise identification and differentiation of species is therefore of paramount importance to reconstruct the invasion history. Genetic studies are indispensable in the case of morphologically conservative taxonomic groups. 2. We analysed the Pontocaspian freshwater amphipods Dikerogammarus that have successfully invaded the benthos of large Central European rivers. Taxonomic uncertainties were clarified by phylogenetic analyses of mitochondrial 16S and COI genes. The three-way partitioning of allozyme genotypes in a syntopic population further corroborated the…
