1/42. Clinical characterization of Dobrava hantavirus infections in germany.There is increasing evidence that Dobrava (DOBV) but not Hantaan (HTNV) hantavirus is a hemorrhagic fever with renal syndrome (HFRS) causing agent in Central europe. However, only single clinical cases of HFRS due to acute DOBV infection have been described so far. We report on three male patients from a non-endemic hantavirus focus in Northern germany who suffered from mild to moderate HFRS strongly resembling nephropathia epidemica. serotyping by detection of hantavirus species-specific neutralizing antibodies revealed acute infections by the HTNV-related hantavirus DOBV in all three cases. Since DOBV infections in the Balkans frequently present as severe HFRS, our cases suggest that Central-European DOBV infections have a different, less severe clinical outcome. These differences in DOBV virulence towards humans might be due to the existence of different genetic lineages of DOBV.- - - - - - - - - - ranking = 1keywords = fever (Clic here for more details about this article) |
2/42. Anatomo-pathologic observations on epidemic nephropathy.Two cases of necropsy and 5 cases of renal biopuncture were studied on the occassion of an epidemic of "hemorrhagic fever with renal syndrome" identified in mountainous areas of Transylvania. The prevalent pathogenic process was capillary toxicosis which injured the renal tubules and vessels. The severity of the disease was determined by the phenomena of tubular failure, by the hemorrhagic syndrome and shock.- - - - - - - - - - ranking = 1keywords = fever (Clic here for more details about this article) |
3/42. A case of torsade de pointes associated with hypopituitarism due to hemorrhagic fever with renal syndrome.We describe a 51-yr-old man presenting with syncope due to torsade de pointes. The torsade de pointes was refractory to conventional medical therapy, including infusion of isoproterenol, MgSO4, potassium, lidocaine, and amiodarone. His past history, physical findings, and hormone study confirmed that QT prolongation was caused by anterior hypopituitarism that developed as a sequela of hemorrhagic fever with renal syndrome. The long QT interval with deep inverted T wave was completely normalized 4 weeks after starting steroid and thyroid hormone replacement. Hormonal disorders should be considered as a cause of torsade de pointes, because this life-threatening arrhythmia can be treated by replacing the missing hormone.- - - - - - - - - - ranking = 5keywords = fever (Clic here for more details about this article) |
4/42. hemorrhagic fever with renal syndrome: diagnostic problems with a known disease.hemorrhagic fever with renal syndrome (HFRS), caused by different hantaviruses, is a distinct clinical syndrome endemic in several parts of asia and europe. However, the clinical picture can sometimes be indistinguishable from that of other infectious or noninfectious diseases. In this report we describe a clinical case, which is a rare occurrence but is a prime example of the difficulties in the diagnosis of HFRS in areas with a low prevalence of the disease.- - - - - - - - - - ranking = 5keywords = fever (Clic here for more details about this article) |
5/42. hemorrhagic fever with renal syndrome presenting with hemophagocytic lymphohistiocytosis.Hemophagocytic lymphohistiocytosis--which is associated with a variety of infections, malignant neoplasms, autoimmune diseases, and immunodeficiencies--is an uncommon syndrome with a rapidly fatal outcome. We describe the first case of hemorrhagic fever with renal syndrome due to hantaan virus presenting with reactive hemophagocytosis.- - - - - - - - - - ranking = 5keywords = fever (Clic here for more details about this article) |
6/42. Acute disseminated encephalomyelitis following nephropathia epidemica.Acute disseminated encephalomyelitis (ADEM) is an acute monophasic inflammatory and demyelinating disease of the central nervous system (CNS) occurring days to weeks after a virus infection or vaccination. Nephropathia epidemica (NE) is a haemorrhagic fever with renal syndrome caused by puumala virus, with endemic regions in europe, especially scandinavia and Western russia. We describe a case of severe nephropathia epidemica requiring dialysis, followed by severe CNS symptoms caused by ADEM. To our best knowledge this is the first case in the literature in which NE caused ADEM.- - - - - - - - - - ranking = 21509.28151488keywords = haemorrhagic fever, fever (Clic here for more details about this article) |
7/42. Double trouble: hemorrhagic fever with renal syndrome and leptospirosis.The clinical picture of hemorrhagic fever with renal syndrome can closely mimic that of unicteric leptospirosis and vice versa. This is the first description of dual infection with Dobrava virus and leptospira and alteration of immune parameters in a Croatian soldier.- - - - - - - - - - ranking = 5keywords = fever (Clic here for more details about this article) |
8/42. Immune parameters in hemorrhagic fever with renal syndrome during the incubation and acute disease: case report.We describe immune parameters in a Croatian soldier who presented with mild flu-like symptoms and interstitial inflammatory infiltrate in the lungs on an X-ray during the incubation phase of hemorrhagic fever with renal syndrome (HFRS). enzyme-linked immunosorbent assay (ELISA) IgM and polymerase chain reaction (PCR) were negative. Two weeks later, he developed HFRS caused by the puumala virus. We performed two-color immunofluorescence cytometry with monoclonal antibodies identifying the activation markers on T cells. serum samples were also examined by enzyme immunoassay (EIA) for the presence of interleukins IL-2 and IL-6 and their soluble receptors (sR). The analysis of early and late activation markers during the period of incubation revealed a small increase in the percentage of helper (CD4 CD25 ) T cells and no significant increase in total activated (HLA-DR TCR ) and cytotoxic (CD8 CD71 ) T cells as compared with healthy controls. In the serum, only the concentration of soluble IL-6 receptor was increased. However, when the patient developed HFRS, all activation markers on T cells increased. Concentrations of sIL-2Ralpha and IL-6 remained increased two and six days after HFRS onset, respectively, whereas sIL-6R increased six days after HFRS onset. IL-2 concentration did not change. Our case indicates that rapid, modern diagnostic tools are necessary in the diagnosis of infectious diseases and their differential diagnosis. Immunological tests, which provide information on the patient immune status and especially on early changes in immune parameters, may contribute to the improvement of the diagnosis, prognosis, and therapy of HFRS.- - - - - - - - - - ranking = 5keywords = fever (Clic here for more details about this article) |
9/42. Pulmonary-renal syndrome due to hemorrhagic fever with renal syndrome: an unusual manifestation of puumala virus infection in france.The authors report about a patient who presented with acute respiratory failure, bilateral alveolar infiltrates, without signs of fluid overload, and acute renal failure. Percutaneous renal biopsy revealed acute interstitial nephritis with medulla hemorrhages. serologic tests for puumala virus infection were positive. hemorrhagic fever with renal syndrome should be considered when patients present with pulmonary-renal syndrome.- - - - - - - - - - ranking = 5keywords = fever (Clic here for more details about this article) |
10/42. puumala virus pulmonary syndrome in a Romanian immigrant.Hantaviruses belong to the bunyaviridae family, which is comprised of Bunyavirus, phlebovirus, nairovirus, and Hantavirus. Euroasiatic Hantaviruses belong to two distinct subfamilies: murinae (comprising Hantaan, Dobrava, and Seoul viruses), which are responsible for hemorrhagic fever with renal syndrome (HFRS), and arvicolinae (comprising puumala virus), responsible for nephropathia epidemica (NE) and HFRS. On the contrary, the New World Hantavirus belongs to the sigmodontinae subfamily and includes the North American viruses: Sin Nombre, Monongahela; new york, Bayou, Black Creek Canal, and the South American, which comprise the Andes, Oran, Lechiguanas, Laguna Negra, Juquitiba; both groups are responsible for the hantavirus pulmonary syndrome (HPS).- - - - - - - - - - ranking = 1keywords = fever (Clic here for more details about this article) |
