Acute renal failure (ARF) requiring hemodialysis is not common among patients affected by influenza. We report two unvaccinated adult patients with smoking habit, which were admitted with severe influenza A H1N1pdm09 that evolved with shock and required mechanical ventilation. Both patients developed progressive renal failure with oliguria/anuria, associated with urinary of inflammatory sediment with proteinuria, microhematuria and in one case also with hypocomplementemia, suggesting acute glomerulonephritis...

Sensitive and rapid diagnostic systems for avian influenza (AI) virus are required to screen large numbers of samples during a disease outbreak and to prevent the spread of infection. In this study, we employed a novel fluorescent dye for the rapid and sensitive recognition of AI virus. The styrylpyridine phosphor derivative was synthesized by adding allyl bromide as a stable linker and covalently immobilizing it on latex beads with antibodies generating the unique Red dye 53-based fluorescent probe. The performance of the innovative rapid fluorescent immnunochromatographic test (FICT) employing Red dye 53 in detecting the AI virus (A/H5N3) was 4-fold and 16-fold higher than that of Europium-based FICT and the rapid diagnostic test (RDT), respectively...

Bluetongue virus (BTV) is an infectious, non-contagious viral disease of domestic and wild ruminants that is transmitted by adult females of certain Culicoides species. Since 2006, several serotypes including BTV-1, 2, 4, 6, 8, 9 and 16, have spread from the Mediterranean basin into Northern Europe for the first time. BTV-8 in particular, caused a major epidemic in northern Europe. As a result, it is evident that most European countries are at risk of BTV infection. The objective of this study was to develop and validate a real-time reverse transcriptase-polymerase chain reaction (rRT-PCR) assay based on TaqMan technology for the detection of representative strains of all BTV serotypes...

ABSTRACTHemodialysis (HD) and peritoneal dialysis (PD) represent two complementary modalities of renal replacement therapy (RRT) for end-stage renal disease patients. Conversion between the two modalities is frequent and more likely to happen from PD to HD. Every year, 10% of PD patients convert to HD, suggesting the need for recommendations on how to proceed with the creation of a vascular access in these patients. Criteria for selecting patients who would likely fail PD, and therefore take advantage of a backup access, are undefined...

BACKGROUND: Coronaviruses (CoVs) are large ribonucleic acid (RNA) viruses causing primarily respiratory disease in humans. A novel human coronavirus, subsequently named middle east respiratory syndrome coronavirus (MERS-CoV), was first reported in Saudi Arabia in September of 2012. With increasing numbers of infections and deaths from MERS-CoV, development of a rapid and reliable kit was crucial to prevent further spread of MERS-CoV. OBJECTIVES: In this study, we present two real-time reverse-transcription polymerase chain reaction (rRT-PCR) assays for in-house rapid and sensitive diagnostic testing of MERS-CoV, detecting the regions upstream of the envelope gene (upE) and open reading frame (ORF) 1b, respectively, for initial screening and final confirmation of MERS-CoV infection, as recommended by the world health organization (WHO)...

Zika virus (ZIKV) infection during pregnancy has been linked to severe birth defects, and the epidemiologic situation of the ZIKV epidemic in Ecuador is poorly understood. Guayaquil, Ecuador, has a tropical climate and experiences frequent outbreaks of dengue and chikungunya virus, and in December 2015, ZIKV was identified. Given the well-documented effects of ZIKV in pregnancy, including microcephaly, we tested for the presence of ZIKV in both plasma and cervical cytology of pregnant women. We report the identification of a population of pregnant women with a high incidence of ZIKV infection detected in the plasma and lower reproductive tract...
