Ninety six patients with hemorrhagic fever and the renal syndrome were followed up. Reaferon was included into the complex therapy of 57 cases. The drug was administered intramuscularly in a dose of 2 x 10(6) IU twice a day for 5 days. The use of reaferon in the complex therapy resulted in a decrease in the period of the general intoxication by 3.4 +/- 1.3 days. The use of the drug at the initial stages prevented acute renal failure. When reaferon was used at the stage of oliguria, the level of proteinuria and the risk of the further affection of the kidneys lowered. After the completion of the treatment course with the use of reaferon, a significant increase in the content of the T-helper cells was observed which could be indicative of an activation of the mechanisms providing the immunity development and pathogen elimination. Reaferon promoted a decrease in the concentration of the circulating immune complexes of the blood serum. No significant adverse reactions to the use of reaferon were recorded. The results are in favour of the reaferon use in complex therapy of patients with hemorrhagic fever and the renal syndrome, especially at the initial stages until the syndrome of acute renal failure developed.

Hantavirus activity in rodents and human beings in Argentina has been known since the 1980's. In this study, we retrospectively investigated hantavirus infections among Argentine Hemorrhagic Fever (AHF) cases notified between 1987 and 1994, without virological confirmation. IgG and IgM antibodies to hantavirus were tested by ELISA. Among 1028 patients included in the study, we found 13 recent infections (1.26%) and 13 remote infections (1.26%). IgG antibodies determined in 745 healthy persons living in the same localities of recent infection cases, gave only one positive result (0.13%). Nine of the 13 recent infections had the clinical presentation of Hemorrhagic Fever with Renal Syndrome (HFRS) while the other four were in the form of Hantavirus Pulmonary Syndrome (HPS). We performed a clinical and epidemiological comparison between the nine patients with FHSR and two paired control groups: one with confirmed AHF and the other with Febrile Syndrome of Undetermined Etiology (FSUE), which were negative for hantavirus, Junin and LCM. There were no differences between clinical signs or symptoms. Nevertheless, normal or high leucocyte counts, with thrombocytopenia, hemoconcentration, high creatinine levels and proteinuria in HFRS cases resulted useful for differential diagnosis. These results showed the coexistence of Junin virus and hantaviruses in the endemic area of AHF, and indicate the importance of including the infection with these viruses in the differential diagnosis of hemorrhagic fevers and respiratory distress syndromes of unknown etiology. The clinical variability found could be related to the presence of more than one hantavirus serotype in our country.

Hantaviruses are etiologic agents of hemorrhagic fever with renal syndrome, an acute illness characterized by acute renal insufficiency, proteinuria, and hemodynamic instability. Recently, a New World form of hantavirus disease, hantavirus pulmonary syndrome (HPS), was recognized; in this form, pulmonary edema is prominent, but renal insufficiency is generally lacking. HPS cases from the southeastern United States may be exceptional in that they have exhibited both pulmonary and renal manifestations. One case in Louisiana and one case in Florida were linked to infection by the distinct but closely related Bayou and Black Creek Canal hantaviruses, respectively. We report a nonfatal case of HPS caused by Bayou hantavirus that occurred in eastern Texas. Clinical manifestations included pulmonary and renal insufficiency and myositis, which had previously been observed in the patient from Florida. The occurrence of distinctive clinical abnormalities in HPS cases from the southeastern United States supports the concept that there are clinically significant differences between western and southeastern forms of HPS.

Hantaviruses cause two severe human diseases: hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS). Approximately 200,000 cases are reported annually, and there is to date no specific treatment available. A major obstacle in studying the medical aspects of HFRS and HPS has been the lack of an adequate animal model. Here we show that infection of cynomolgus macaques by wild-type Puumala hantavirus resulted in typical signs of HFRS including lethargy, anorexia, proteinuria, and/or hematuria, in addition to cytokine (interleukin 6 [IL-6], IL-10, and tumor necrosis factor alpha), C-reactive protein, creatinine, and nitric oxide responses. Viral RNA was detected in plasma from days 3 to 7 postinoculation until days 24 to 28 postinoculation, infectious virus was recovered, and the virus-specific immune responses (immunoglobulin M [IgM], IgG, and neutralizing antibodies) mimicked those seen in humans. The results indicated that the monkey model will provide a valuable tool for studies of pathogenesis, candidate vaccines, and antivirals for hantavirus disease.

Hemorrhagic fever with renal syndrome (HFRS) is caused by the Hantaviruses, a group enveloped RNA viruses transmitted through contact with infected rodent urine or feces. Although distributed widely through Europe, Asia, and the New World, infections acquired in Korea, China, and Russia tend to be among the most severe. The initial presentation of HFRS is extremely variable, but generally includes fever, malaise, headache and abdominal pain. Laboratory findings that may lead to the diagnosis include thrombocytopenia, azotemia, elevated serum creatinine, or proteinuria. We present the case of a patient that acquired hemorrhagic fever with renal syndrome in South Korea.

Nephropathia epidemica (NE) is a hemorrhagic fever with renal syndrome caused by Puumala hantavirus. Its long-term prognosis is considered favorable. There are, however, some reports about subsequent hypertension, glomerular hyperfiltration, and proteinuria after previous hantavirus infection. Therefore, we studied 36 patients 5 and 10 years after acute NE, with 29 seronegative controls. Office blood pressure, ambulatory 24-h blood pressure (ABP), glomerular filtration rate (GFR), and proteinuria were examined. Hypertensive subjects were defined as those patients having increased ambulatory or office blood pressure, or receiving antihypertensive therapy. Office blood pressure was used to define hypertension only if ABP was not determined. At 5 years, the prevalence of hypertension was higher among NE patients than in controls (50 vs 21%, P=0.020). At 10 years, the difference between the groups was no more significant (39 vs 17%, P=0.098). Five years after NE, patients showed higher GFR (121+/-19 vs 109+/-16 ml/min/1.73 m(2), P=0.012) and urinary protein excretion (0.19 g/day, range 0.12-0.38 vs 0.14 g/day, range 0.09-0.24, P=<0.001) than controls. At 10 years, there were no more differences in GFR or protein excretion between the groups (GFR: 113+/-20 vs 108+/-17 ml/min/1.73 m(2), P=0.370; proteinuria: 0.14 g/day, range 0.07-0.24 vs 0.13 g/day, range 0.06-0.31, P=0.610). In conclusion, the 10-year prognosis of NE is favorable, as glomerular hyperfiltration and slight proteinuria detected at 5 years disappeared during the longer follow-up. However, the possibility exists that NE may predispose some patients to the development of hypertension.

Nephropathia epidemica (NE) is a mild form of hemorrhagic fever with renal syndrome, assumed to have a favorable prognosis. NE patients who manifested a higher glomerular filtration rate and mean systolic blood pressure, and more proteinuria, versus controls at 5 years of follow-up demonstrated no major abnormalities after 10 years. Antihypertensive treatment was, however, more common. Could NE predispose some patients to develop hypertension after all?

Both scrub typhus and hemorrhagic fever with renal syndrome (HFRS) are severely epidemic in northern China and often present with acute undifferentiated fever. To correctly distinguish the two diseases at an early stage, we collected and compared clinical and routine laboratory data of 46 patients with confirmed scrub typhus and 49 patients with confirmed HFRS presenting to the outpatient departments of three town hospitals in northern China. Most patients with HFRS but none of the patients with scrub typhus had hemorrhagic manifestations. Retro-orbital pain, lumbar back pain, flank tenderness, proteinuria, and occult blood in urine often occurred in patients with HFRS. However, skin eschar, regional lymphadenopathy, and maculopapular rash were more commonly found in patients with scrub typhus. In addition, platelet counts in patients with HFRS were significantly lower than in patients with scrub typhus. These findings will be useful for physicians to distinguish scrub typhus from HFRS.

A spread of hantavirus infections causing hemorrhagic fever with renal syndrome is one of the rising epidemiological problems in the world. There is evidence that this type of viruses exists in almost all European countries. It is known that in Poland all the species of wild rodents hosting European hantaviruses are present. However, the data on hantavirus are very limited and information on incidence and prevalence of hantavirus infections among humans and animals in our country is lacking. Up to now, only one study in Poland has dealt with hantavirus infections in humans. Therefore the aim of the presented study was to show whether those infections are present in Poland and how prevalent they are. Two risk groups of hantavirus infection were investigated: group I--people with renal disorders (hospitalized patients with proteinuria and people suspected to hantavirus infection; n=30 people) and group II--healthy people employed at the universities, scientific institutions who due to their profession have contact with small rodents as well as students who captured those rodents when practicing or preparing their master theses (n=76) and forest workers (n=86). No one from the group of patients with renal disorders was positive for hantavirus Puumala IgG. Moreover, none of the forest workers had evidence of hantavirus infection. The hantavirus IgG were found only in the group of mammologists--19% persons were positive. Mammologists are an occupational subpopulation who remain in direct contact with host and/or with host excretions (virus is present in urine, feces, saliva of infected animals) and seem to be the most sensitive indicator of hantaviruses presence in environment. These results prove occurrence of hantavirus infections in Poland, however it seems that they are not very prevalent.

A 38 year old patient presented with fever, myalgic abdominal pain, nose bleeding and acute renal failure since five days. A combination of thrombocytopenia, proteinuria, elevated CrP and creatinin is common in hemorrhagic fever with renal syndrome (HFRS) due to Hantavirus infection. The benigne form is called Nephropathia epidemica. Dialysis is infrequently required by patients with the Puumala virus. Other infection (e.g. malaria, leptospirosis, yellow fever) and systemic diseases (e.g. collagenosis or vasculitis) are considered.
