Parvovirus B19 Genotype Specific Amino Acid Substitution in NS1 Reduces the Protein's Cytotoxicity in Culture
2010
A clinical association between idiopathic liver disease and parvovirus B19 infection has been observed. Fulminant liver failure, not associated with other liver-tropic viruses, has been attributed to B19 in numerous reports, suggesting a possible role for B19 components in the extensive hepatocyte cytotoxicity observed in this condition. A recent report by Abe and colleagues (Int J Med Sci. 2007;4:105-9) demonstrated a link between persistent parvovirus B19 genotype I and III infection and fulminant liver failure. The genetic analysis of isolates obtained from these patients demonstrated a conservation of key amino acids in the nonstructural protein 1 (NS1) of the disease-associated genotyp…
Sporting Activities and Quality of Life in Children With Hemophilia: An Observational Study.
2016
Sports activities are part of multidisciplinary treatments in people with hemophilia. Aim: The objective of this study was to assess the incidence of sports activities in the quality of life as perceived by children with hemophilia. Methods: A total of 53 children with hemophilia aged 7 to 13 years and 51 children without hemophilia were evaluated. The perception of quality of life, clinical variables, and the frequency of sports activities were registered. The joint condition of patients with hemophilia was measured with the Spanish version of the Haemophilia Joint Health Score. Results: There were no significant differences in the perception of quality of life between children with hemoph…
Synthesis and induction of G0–G1 phase arrest with apoptosis of 3,5-dimethyl-6-phenyl-8-(trifluoromethyl)-5,6-dihydropyrazolo[3,4-f][1,2,3,5]tetrazep…
2007
The multistep synthesis of 3,5-dimethyl-6-phenyl-8-(trifluoromethyl)-5,6-dihydropyrazolo[3,4-f][1,2,3,5]tetrazepin-4(3H)-one 15 has been carried out. The compound showed antiproliferative and apoptotic effects against K562, K562-R (imatinib mesilate resistant), HL60 and multidrug resistant (MDR) HL60 cell lines. Compound 15 showed a pro-apoptotic activity against HL60 and K562 resistant cell lines markedly higher than etoposide and busulfan, respectively. Flow cytometry studies carried out on K562 cells allowed to establish that 15 induces G0-G1 phase arrest followed by apoptosis.
Socio-environmental variables and transmission risk of lymphatic filariasis in central and northern Mozambique
2013
Lymphatic filariasis (LF) is endemic in Mozambique, where it is caused by Wuchereria bancrofti with Culex quinquefasciatus as the main vector. It affects approximately 10% of the population (2 million) with about 16 million at risk. Prevalence rates in 40 out of 65 districts that together comprise the four endemic provinces Niassa, Cabo Delgado, Nampula and Zambezia were analysed with the aim of elucidating the socio-environmental variables influencing the transmission. The levels of prevalence were divided into six ranks and certain climatic, environmental and social factors were considered independent variables. A climadiagram was created and the LF risk and the water budget-based index w…
Rasburicase-induced Methemoglobinemia: A Case Report and Literature Review.
2020
Rasburicase is a recombinant urate oxidase enzyme indicated for tumor lysis syndrome, a potential life-threatening oncologic emergency that occurs most commonly during initial chemotherapy for hematological malignancies. As a result of the defects in the physiological antioxidant pathway, erythrocytes of patients with glucose-6-phosphate dehydrogenase deficiency are not protected against the oxidizing stress exerted by hydrogen peroxide generated with the administration of rasburicase. The authors report a 14-year-old patient, diagnosed with T-cell acute lymphoblastic leukemia, who developed methemoglobinemia and hemolytic anemia with low oxygen saturation after starting steroids, hyperhydr…
Effectiveness of cyclosporine and mycophenolate mofetil in a child with refractory evans syndrome
2011
Evans Syndrome is a rare autoimmune disease consisting of hemolytic anemia, thrombocytopenia and/or neutropenia. It may be associated with other autoimmune or lymphoproliferative diseases. Its course can be extremely serious and, rarely, even life-threatening
Management of anemia induced by triple therapy in patients with chronic hepatitis C: Challenges, opportunities and recommendations
2013
SummaryThe addition of protease inhibitors, boceprevir or telaprevir, to peginterferon+ribavirin (PegIFN/RBV) increases the frequency as well as the severity, and hence, clinical relevance of anemia, which has now become one of the major complications associated with triple therapy. Most significant factors associated with anemia in patients receiving triple therapy include older age, lower body mass index (BMI), advanced fibrosis, and lower baseline hemoglobin. The variability in inosine triphosphate pyrophosphatase (ITPA) gene, which encodes a protein that hydrolyses inosine triphosphate (ITP), has been identified as an essential genetic factor for anemia both in dual and triple therapy. …
Liver Involvement in Hodgkin's Lymphoma: Types of Injuries and Therapeutic Implications
2017
The hepatocytolysis raises questions on following therapeutic conduct when it occurs during chemotherapy for Hodgkin's lymphoma, expression of its liver toxicity. But the onset of primary liver Hodgkin's lymphoma, including the form manifested by acute liver failure, poses even greater problems, as in the case of occurrence of vanishing bile duct syndrome - expression of a paraneoplastic syndrome, hemophagocytic lymphohistiocytosis, peliosis hepatis or association of lymphoma with infection with hepatitis viruses or human immunodeficiency virus or different autoimmune diseases. This review summarizes the clinical experience acquired on the relationship between Hodgkin's lymphoma and liver, …

5-methylcytosine modification of an Epstein–Barr virus noncoding RNA decreases its stability
2020
Many cellular noncoding RNAs contain chemically modified nucleotides that are essential for their function. The Epstein–Barr virus expresses two highly abundant noncoding RNAs called EBV-encoded RNA 1 (EBER1) and EBER2. To examine whether these viral RNAs contain modified nucleotides, we purified native EBERs from EBV-infected cells and performed mass spectrometry analysis. While EBER2 contains no modified nucleotides at stoichiometric amounts, EBER1 was found to carry 5-methylcytosine (m5C) modification. Bisulfite sequencing indicated that a single cytosine of EBER1 is methylated in ∼95% of molecules, and the RNA methyltransferase NSUN2 was identified as the EBER1-specific writer. Intrigui…
