Abstract
Puumala hantavirus (PUUV) causes hemorrhagic fever with renal syndrome. We aimed to evaluate whether ABO and rhesus blood groups associate with the susceptibility or the severity of PUUV infection. We analyzed blood groups in 289 adult patients treated in Tampere University hospital due to PUUV infection during the years 1982–2017. Patients’ blood group distribution was compared to that of healthy, voluntary blood donors living in the Tampere University Hospital responsibility area (n = 21,833). The severity of PUUV infection, as judged by the severity of acute kidney injury (AKI), thrombocytopenia, inflammation, capillary leakage, and the length of hospital care, was analyzed across the groups. The ABO and rhesus blood group distributions did not differ between the patients and blood donors. Patients with non-O blood groups had lower systolic blood pressure compared to patients with blood group O, but there was no difference in other markers of capillary leakage or in the severity of AKI. Minor deviations in the number of platelets and leukocytes were detected between the O and non-O blood groups. To conclude, patients with blood group O may be less susceptible to hypotension, but otherwise blood groups have no major influences on disease susceptibility or severity during acute PUUV infection.

Abstract
Central and peripheral hormone deficiencies have been documented during and after acute hantavirus infection. Thrombocytopenia and coagulation abnormalities are common findings in haemorrhagic fever with renal syndrome (HFRS). The associations between coagulation and hormonal abnormalities in HFRS have not been studied yet. Forty-two patients diagnosed with Puumala virus (PUUV) infection were examined during the acute phase and on a follow-up visit approximately one month later. Hormonal defects were common during acute PUUV infection. Overt (clinical) hypogonadism was identified in 80% of the men and approximately 20% of the patients had overt hypothyroidism. At the one-month follow-up visit, six patients had central hormone deficits. Acute peripheral hormone deficits associated with a more severe acute kidney injury (AKI), longer hospital stay and more severe thrombocytopenia. Half of the patients with bleeding symptoms had also peripheral hormonal deficiencies. Patients with free thyroxine levels below the reference range had higher D-dimer level than patients with normal thyroid function, but no thromboembolic events occurred. Acute phase hormonal abnormalities associate with severe disease and altered haemostasis in PUUV infection.

Abstract
Puumala hantavirus (PUUV) causes a hemorrhagic fever with renal syndrome characterized by thrombocytopenia, increased capillary leakage, and acute kidney injury (AKI). As glucosuria at hospital admission predicts the severity of PUUV infection, we explored how plasma glucose concentration associates with disease severity. Plasma glucose values were measured during hospital care in 185 patients with PUUV infection. They were divided into two groups according to maximum plasma glucose concentration: P-Gluc < 7.8 mmol/L (n = 134) and P-Gluc ≥ 7.8 mmol/L (n = 51). The determinants of disease severity were analyzed across groups. Patients with P-Gluc ≥7.8 mmol/L had higher hematocrit (0.46 vs. 0.43; p < 0.001) and lower plasma albumin concentration (24 vs. 29 g/L; p < 0.001) than patients with P-Gluc < 7.8 mmol/L. They presented with higher prevalence of pulmonary infiltrations and pleural effusion in chest radiograph, higher prevalence of shock and greater weight change during hospitalization. Patients with P-Gluc ≥ 7.8 mmol/L were characterized by lower platelet count (50 vs. 66 × 109/L; p = 0.001), more severe AKI (plasma creatinine 272 vs. 151 µmol/L; p = 0.001), and longer hospital treatment (8 vs. 6 days; p < 0.001) than patients with P-Gluc < 7.8 mmol/L. Plasma glucose level is associated with the severity of capillary leakage, thrombocytopenia, inflammation, and AKI in patients with acute PUUV infection.

Abstract
Hantaan viruses (HTNVs) are zoonotic pathogens transmitted mainly by rodents and capable of infecting humans. Increasing knowledge of the human response to HTNV infection can guide the development of new preventative vaccines and therapeutic strategies. Here, we show that HTNV can infect CD8+ T cells in vivo in patients diagnosed with hemorrhagic fever with renal syndrome (HFRS). Electron microscopy-mediated tracking of the life cycle and ultrastructure of HTNV-infected CD8+ T cells in vitro showed an association between notable increases in cytoplasmic multivesicular bodies and virus production. Notably, based on a clinical cohort of 280 patients, we found that circulating HTNV-infected CD8+ T cell numbers in blood were proportional to disease severity. These results demonstrate that viral infected CD8+ T cells may be used as an adjunct marker for monitoring HFRS disease progression and that modulating T cell functions may be explored for new treatment strategies.

Abstract
BACKGROUND Puumala orthohantavirus (PUUV) causes hemorrhagic fever with renal syndrome (HFRS). Patients with HFRS have an activated coagulation system with increased risk of disseminated intravascular coagulation (DIC) and venous thromboembolism (VTE). The aim of the study was to determine whether circulating extracellular vesicle tissue factor (EVTF) activity levels associates with DIC and VTE (grouped as intravascular coagulation) in HFRS patients. METHODS Longitudinal samples were collected from 88 HFRS patients. Patients were stratified into groups of those with intravascular coagulation (n = 27) and those who did not (n = 61). We measured levels of circulating EVTF activity, fibrinogen, activated partial prothrombin time, D-dimer, tissue plasminogen activator (tPA), plasminogen activator inhibitor 1 (PAI-1), and platelets. RESULTS Plasma EVTF activity was transiently increased during HFRS. Levels of EVTF activity were significantly associated with plasma tPA and PAI-1, suggesting that endothelial cells could be a potential source. Patients with intravascular coagulation had significantly higher peak EVTF activity levels compared with those who did not, even after adjustment for sex and age. The peak EVTF activity value predicting intravascular coagulation was 0.51 ng/L with 63% sensitivity and 61% specificity with area under the curve = 0.63 (95% confidence interval, 0.51-0.76) and P = .046. CONCLUSIONS Plasma EVTF activity during HFRS is associated with intravascular coagulation.

Abstract
Background Puumala hantavirus (PUUV) infected patients typically suffer from acute kidney injury (AKI). Adipokines have inflammation modulating functions in acute diseases including AKI. We examined plasma levels of three adipokines (resistin, leptin, and adiponectin) in acute PUUV infection and their associations with disease severity. Methods This study included 79 patients hospitalized due to acute PUUV infection. Plasma resistin, leptin, adiponectin, as well as IL-6 and CRP, were measured at the acute phase, recovery phase and one year after hospitalization. Results Plasma resistin levels were significantly higher in the acute phase compared to the recovery phase and one year after (median resistin 28 pg/mL (11–107) vs. 17 pg/mL (7–36) vs. 14 pg/mL (7–31), p<0.001). Maximum resistin concentration correlated with maximum plasma creatinine levels (r = 0.63; p<0.001). The higher the amount of albuminuria in the urine dipstick test (0–1+, 2+ or 3+) at admission, the higher the median of maximum resistin (24.7 pg/mL, 25.4 pg/mL and 39.6 pg/mL, respectively, p = 0.002). High resistin was also an independent risk factor for severe AKI (creatinine ≥353.6μmol/L) (OR 1.08, 95% CI 1.02–1.14). Neither plasma leptin nor adiponectin level had any correlation with creatinine concentration or the amount of albuminuria. Conclusions Plasma resistin independently associates with the severity of AKI in acute PUUV infection. The association of resistin with the amount of albuminuria suggests that the level of plasma resistin is not only influenced by renal clearance but could have some role in the pathogenesis of AKI during PUUV infection.

Abstract
Objective To investigate the changes of plasma melatonin (MLT) level in patients with hemorrhagic fever with renal syndrome (HFRS) and the relationships between the MLT level and the disease stage or severity. Methods The plasma samples were collected from 14 HFRS patients at acute stage or convalescent stage and 14 normal controls. After extraction, competitive enzyme-linked immunosorbent assay (CELISA) was used to detect the content of MLT in the plasma. The plasma MTL levels were compared between different severities or stages of HFRS patients and the normal controls. Meanwhile, the relationships between the MLT level and clinical indicators such as white blood cell (WBC) count were analyzed. Results The plasma MLT level of HFRS patients at the acute stage were significantly lower than that of the normal controls, and also significantly lower than that at the convalescence of HFRS. At the acute stage, the plasma MLT level of mild/severe HFRS patients was lower than that of critical patients. Moreover, the level of plasma MLT was negatively correlated with WBC count in HFRS patients at acute or convalescence stages. Conclusion MLT may be involved in the regulation of inflammatory responses in HFRS patients, which may affect the pathogenesis and disease progression of HFRS.

Abstract
Hemorrhagic fever with renal syndrome (HFRS) is characterized by endothelial dysfunction with capillary leakage without obvious cytopathology in the capillary endothelium. The aim of the study was to analyze the kinetics of vascular endothelial growth factor (VEGF) and its soluble receptor (sVEGFR-2) in HFRS patients infected with Dobrava (DOBV) or Puumala virus (PUUV). VEGF and sVEGFR-2 levels were measured in daily plasma and urine samples of 73 patients with HFRS (58 with PUUV, 15 with DOBV) and evaluated in relation to clinical and laboratory variables. In comparison with the healthy controls, initial samples (obtained in the first week of illness) from patients with HFRS had higher plasma and urine VEGF levels, whereas sVEGFR-2 levels were lower in plasma but higher in urine. VEGF levels did not differ in relation to hantavirus species, viral load, or the severity of HFRS. The comparison of VEGF dynamics in plasma and urine showed the pronounced secretion of VEGF in urine. Significant correlations were found between daily VEGF/sVEGFR-2 levels and platelet counts, as well as with diuresis: the correlations were positive for plasma VEGF/sVEGFR-2 levels and negative for urine levels. In addition, patients with hemorrhagic manifestations had very high plasma and urine VEGF, together with high urine sVEGFR-2. Measuring the local secretion of sVEGFR-2 in urine might be a useful biomarker for identifying HFRS patients who will progress to severe disease.

Abstract
BACKGROUND Until now, there is non-specific treatment, and exploring early and novel biomarkers to determine the disease severity and prognosis of hemorrhagic fever with renal syndrome (HFRS) would be of importance for clinician to take systematic and timely intervention. This study observed the expression of plasma sCD138, a soluble component shedding from the glycocalyx (GCX) to the circulating blood, and evaluated its predictive value on disease severity and prognosis of HFRS. METHODS One hundred and seventy-six patients with HFRS who were treated at our center between January 2011 and December 2013 were randomly enrolled in this study. The patients were divided into a mild-type group, a moderate-type group, a severe-type group and a critical-type group according to the HFRS criteria for clinical classification. Thirty-five blood samples from healthy subjects were obtained as the controls. The concentrations of sCD138 were detected using enzyme linked immunosorbent assay (ELISA). The levels of prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (Fib), albumin (ALB), alanine aminotransferase (ALT), aspartate aminotransferase (AST), white blood cells (WBC), platelets (PLT), glucose (GLU), blood urea nitrogen (BUN) and serum creatinine (Scr) in the samples were routinely tested. The levels of sCD138 among the different types were compared; the correlation among sCD138 and the laboratory parameters mentioned above were analyzed. The predictive effectiveness for prognosis of sCD138 was evaluated using the receiver operating characteristic (ROC) curve analysis. RESULTS Except for the mild-type, the levels of sCD138 in the moderate-, severe- and critical-type patients during the acute stage were significantly higher than that of the convalescent stage and the control (P<0.05). With the aggravation of the disease, the levels of sCD138 during the acute stage had an increasing tendency, while demonstrated no significant difference among the moderate-, severe- and critical-type patients (P>0.05). sCD138 was negatively correlated with Fib, PLT and ALB, and was positively correlated with WBC and AST (P<0.05). sCD138 demonstrated predictive effectiveness for prognosis with the area under the curve (AUC) of 0.778 (P<0.001). CONCLUSION Dynamic detection of plasma sCD138 might be benefit to evaluating the disease severity and prognosis of the patients with HFRS.

Abstract
BACKGROUND Very recently, a novel European hantavirus, Sochi virus, has been discovered which causes severe courses of hantavirus disease with a case fatality rate of about 15 percent. OBJECTIVES We aimed to study to which extent and with which clinical severity children were affected by Sochi virus infection. STUDY DESIGN Sochi virus infection of patients was confirmed by molecular, serological, and epizoonotic studies. Clinical and laboratory parameters were analyzed for the age group of up to 15 years (n = 6) in comparison to all older patients (n = 56). RESULTS 9.7 percent of patients with hantavirus disease studied (6/62) were up to 15 years old. The children showed moderate to severe clinical courses similarly to the situation in adults. CONCLUSIONS While children are in general considered to be less affected by hantavirus infections than adults, in case of highly pathogenic hantaviruses, such as Sochi virus, frequency of clinical cases as well as their clinical course are comparable between children and adults. Therefore, hantavirus disease, particularly in regions endemic to highly pathogenic hantaviruses, should be considered in cases of unclear fever and kidney/pulmonary failure in children.

Abstract
We evaluated the mechanisms of thrombocytopenia and procoagulant changes in relation with clinical variables in a cohort of patients with acute hantavirus disease.Blood samples of 33 prospectively recruited, consecutive, hospitalized patients with acute Puumala virus-induced hemorrhagic fever with renal syndrome (HFRS) were collected acutely and at the recovery visit (control). Serum thrombopoietin (TPO) and activity of plasma microparticles (MPs) from various cell sources were measured with enzyme-linked immunosorbent assay-based methods. The results were related to data on platelet indices and functions, coagulation variables, and clinical disease.Serum TPO was nearly 4-fold higher acutely compared with the control (median 207 pg/mL, range 56-1258 pg/mL vs. median 58 pg/mL, range 11-241 pg/mL, P < 0.001) and coincided with high mean platelet volume (MPV) and immature platelet fraction (IPF%). Prothrombin fragments and D-dimer were high acutely compared with the control (F1 + 2 median 704 pmol/L, range 284-1875 pmol/L vs. median 249 pmol/L, range 118-556 pmol/L, P < 0.001; D-dimer median 2.8 mg/L, range 0.6-34.0 mg/L vs. median 0.4 mg/L, range 0.2-1.1 mg/L, P < 0.001), and associated with low platelet count and severe acute kidney injury (AKI). MPs' procoagulant activity was high acutely only among patients with mild AKI (plasma creatinine below the median at the time of the measurement).Upregulated TPO together with high MPV and IPF% confirm active thrombopoiesis, but do not predict severity of HFRS. Simultaneously, elevated prothrombin fragments and D-dimer suggest increased consumption of platelets in patients with severe AKI. Activity of platelet-derived MPs in HFRS should be studied with flow cytometry in a larger cohort of patients.

Abstract
Hemorrhagic fever with renal syndrome (HFRS) and Crimean-Congo hemorrhagic fever (CCHF) are common representatives of viral hemorrhagic fevers still often neglected in some parts of the world. Infection with Dobrava or Puumala virus (HFRS) and Crimean-Congo hemorrhagic fever virus (CCHFV) can result in a mild, nonspecific febrile illness or as a severe disease with hemorrhaging and high fatality rate. An important factor in optimizing survival rate in patients with VHF is instant recognition of the severe form of the disease for which significant biomarkers need to be elucidated. To determine the prognostic value of High Mobility Group Box 1 (HMGB1) as a biomarker for disease severity, we tested acute serum samples of patients with HFRS or CCHF. Our results showed that HMGB1 levels are increased in patients with CCHFV, DOBV or PUUV infection. Above that, concentration of HMGB1 is higher in patients with severe disease progression when compared to the mild clinical course of the disease. Our results indicate that HMGB1 could be a useful prognostic biomarker for disease severity in PUUV and CCHFV infection, where the difference between the mild and severe patients group was highly significant. Even in patients with severe DOBV infection concentrations of HMGB1 were 2.8-times higher than in the mild group, but the difference was not statistically significant. Our results indicated HMGB1 as a potential biomarker for severe hemorrhagic fevers.

Abstract
The objective is to observe the changes in plasma adiponectin (APN) and its predictive capacity for disease severity and prognosis of hemorrhagic fever with renal syndrome (HFRS).One hundred and five patients who were treated at our center between October 2011 and December 2012 were randomly enrolled in this study. The patients were divided into a mild-type group, a moderate-type group, a severe-type group, and a critical-type group according to the HFRS criteria for clinical classification. Ninety-three plasma samples from the patients in the acute stage and 78 samples from the patients in the convalescent stage were obtained, and 28 samples from healthy subjects were obtained as controls. The concentrations of APN were detected using the enzyme-linked immunosorbent assay. The levels of white blood cells, platelets, hematocrit, albumin, blood urea nitrogen, serum creatinine, and uric acid in the samples were routinely tested. The levels of APN among the different types were compared; the correlation between APN and the laboratory parameters was analyzed. The predictive effectiveness for prognosis of APN and the laboratory parameters as mentioned above were evaluated using the receiver operating characteristic curve analysis.The levels of APN in the mild- and moderate-type patients in the acute stage were significantly higher than the severe-type and control (P < 0.05) and decreased with the severity of the disease, while there were no obvious difference among severe-, critical-type and control groups. The levels of APN in patients in the convalescent stage were higher than the control group (P < 0.05), and the APN levels of the critical-type group were higher compared with the mild-type groups (P < 0.05). Adiponectin was negatively correlated with white blood cells and hematocrit and positively correlated with platelets, albumin, and uric acid (P < 0.001). Adiponectin showed no statistical significance for predicting prognosis, with the area under the curve equal to 0.609 (95% CI: 0.237-0.745, P = 0.215).Adiponectin can be considered as a novel biomarker for disease severity in patients with HFRS, while it seems to have no predictive capacity for prognosis of HFRS.

Abstract
Hemorrhagic fever with renal syndrome (HFRS) is an acute viral infectious disease characterized by fever, hemorrhage and renal failure. HFRS has become a serious public health problem in China. Unfortunately, the pathogenesis of HFRS has not been completely clarified. The aim of this study is to investigate the changes of decoy receptor 3 (DcR3) and to further explore its potential roles in HFRS. The levels of serum DcR3 were measured by sandwich ELISA. We found serum DcR3 levels increased significantly, which reached peak value during the oliguric phase and in the critical group. Moreover, serum DcR3 levels were closely related to the levels of pro-inflammatory cytokines tumor necrosis factor-α (TNF-α) and parameters reflecting kidney injury including BUN, creatinine (Cr) and proteinuria. This study indicates that high levels of serum DcR3 have associations with the disease stages, severity and degree of kidney damage. Meanwhile, our results suggest that DcR3 may play a dual role in HFRS pathogenesis. First, DcR3 is involved in the inflammatory cascade response resulting in capillary permeability and kidney injury in the early stage. Secondly, HTNV infection induced DcR3 expression at the convalescent phase may act as a feed-back mechanism in anti-inflammatory response. Thus, a study of DcR3 is essential for a better understanding of HFRS pathogenesis.

Abstract
To investigate the nature and role of coagulation and complement alterations in the pathogenesis of Korean hemorrhagic fever (KHF), the profiles from the early stages in 27 male patients were serially evaluated. Evidence of disseminated intravascular coagulation (DIC) was observed in 14 of the 27 patients (51.8%) sometime during the course of the disease. The earlier the coagulation tests were performed, the more frequently the evidence of DIC was found. The mean serum C3 concentration was significantly decreased during the early stages, while serum C4 concentrations revealed no significant variation. A significant decrease of the serum C3 concentration, however, was found only in the group with DIC. Korean hemorrhagic fever (KHF) is an acute, systemic disease characterized by fever, hemorrhagic manifestations, and renal failure. This disease has been known to occur from the Pacific Ocean to the Baltic Sea under various synonyms and toponyms including epidemic hemorrhagic fever, hemorrhagic nephrosonephritis and hemorrhagic fever with renal syndrome. Recent investigations demonstrated the identity of these conditions described from Korea, the Soviet Union, Japan, and China. Nephropathia epidemica of Scandinavia was also revealed to have a close serological relation to this disease, but with antigenic differences. The etiologic agent was identified in 1978 by Lee et al., who isolated a viral antigen from a field mouse, Apodemus agrarius coreae, which is the natural reservoir of this disease in Korea. The KHF or Hantaan virus has been propagated in cell cultures and observed electronmicroscopically. In thin sections, the virus was detected within the cytoplasmic granular matrices (viroplasms) of the infected cells. Virus particles were spherical and had an extremely electron-dense core. Negative-contrast staining showed that the virus had an icosahedral structure and annular surface capsomeres. The morphology and morphogenesis of the virus were similar to those of the orbiviruses. The characteristic pathologic findings observed in fatal cases of KHF are congestion and hemorrhage of the renal medulla, hemorrhage in the right atrial wall of the heart, and hemorrhage and necrosis in the anterior lobe of the pituitary gland. The microscopic characteristics of these lesions consist of hemorrhage, coagulation necrosis, and mononuclear cell infiltration. The clinical course of typical KHF may be divided into five phases, each designated for a characteristic physiologic aberration; febrile, hypotensive, oliguric, diuretic, and convalescent.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
The aim of the article is to study actual ration of patients suffered from hemorrhagic fever with renal syndrome (HFRS) and its interaction with the development of arterial hypertension (AH). 296 men aged 20–59 suffered from HFRS were under the care of physician within the period of 1 to 6 years. Among this group 49 cases of arterial hypertension have been registered after HFRS. Frequency method of food product consumption was used to define nutrition. A Russian questionnaire published by Institute of Nutrition (1997) was used. Actual nutrition in men suffered from HFRS is marked by basic nutrients unbalance that is: excessive cholesterol and fat consumption (due to saturated fatty acid), polyunsaturated fatty acid deficiency, sugar overuse and animal protein prevalence over vegetable proteins in patient ration. Atherogenic shift in a ration of patients with AH and suffered from HRFS has been exposed more strongly in all aged group but mostly evident in patients aged 40 and after. Alcohol consumption in men with AH and suffered from HFRS is higher than in healthy peers. Interaction between atherogenic unbalance on the main nutrients in patients with HFRS and arterial hypertension has been defined. Consumatory behavior correction is to be taken to prevent arterial hypertension in recovered patients suffered from HFRS.

Abstract
Cell-free DNA (cf-DNA) in blood represents a promising DNA damage response triggered by virus infection or trauma, tumor, etc. Hantavirus primarily causes two diseases: haemorrhagic fever with renal syndrome (HFRS) and Hantavirus cardiopulmonary syndrome (HCPS), depending on different Hantavirus species. The aim of this study was to evaluate plasma cf-DNA levels in acute phase of HFRS, and to correlate plasma cf-DNA with disease severity and plasma Hanttan virus (HTNV) load. We observed the appearance of cf-DNA in 166 plasma samples from 76 HFRS patients: the plasma cf-DNA levels peaked at the hypotensive stage of HFRS, and then decreased gradually. Until the diuretic stage, there was no significant difference in plasma cf-DNA level between patients and the healthy control. Exclusively in the febrile/hypotensive stage, the plasma cf-DNA levels of severe/critical patients were higher than those of the mild/moderate group. Moreover, the plasma cf-DNA value in the early stage of HFRS was correlated with HTNV load and disease severity. In most of the patients, plasma cf-DNA displayed a low-molecular weight appearance, corresponding to the size of apoptotic DNA. In conclusion, the plasma cf-DNA levels were dynamically elevated during HFRS, and correlated with disease severity, which suggests that plasma cf-DNA may be a potential biomarker for the pathogenesis and prognosis of HFRS.

Abstract
Hantavirus hemorrhagic fever with renal syndrome (HFRS) is a zoonotic disease characterized by acute onset, fever, malaise, and back pain. As the disease progresses, hemorrhagic disturbances and kidney dysfunctions predominate. The examination of tissue collected postmortem supports the premise that virus replication is not responsible for this pathology; therefore, it is widely believed that virus-induced immune responses lead to the clinical manifestations associated with HFRS. The overproduction of inflammatory cytokines is commonly reported in subjects with HFRS and has given rise to the hypothesis that a so-called "cytokine storm" may play a pivotal role in the pathogenesis of this disease. Currently, supportive care remains the only effective treatment for HFRS. Our data show that serum levels of interferon (IFN)-γ, interleukin (IL)-10, CCL2, and IL-12 are upregulated in HFRS cases when compared to healthy controls and the level of upregulation is dependent on the phase and severity of the disease. Furthermore, we observed an association between the mild form of the disease and elevated serum levels of IFN-γ and IL-12. Collectively, these observations suggest that the administration of exogenous IFN-γ and IL-12 may provide antiviral benefits for the treatment of HFRS and, thus, warrants further investigations.

Abstract
Background Hantaan virus (HTNV) could cause a severe lethal hemorrhagic fever with renal syndrome (HFRS) in humans. Despite a limited understanding of the pathogenesis of HFRS, the importance of host-related immune responses in the pathogenesis of HFRS has been widely recognized. CD100/Sema4D has been demonstrated to play an important role in physiological and pathological immune responses, but the functional role of CD100 in infectious diseases has only been inadequately reported. The aim of this study was to investigate the pathological significance of CD100 in patients after HTNV infection. Methodology/Principal Findings Blood samples were collected from 99 hospitalized patients in Tangdu Hospital and 27 health controls. The level of soluble CD100 (sCD100) in plasma were quantified by ELISA and the relationship between sCD100 and the disease course or severity were analyzed. The expressions of membrane CD100 on various subpopulations of peripheral blood mononuclear cell (PBMC) were analyzed by flow cytometry. The results showed that sCD100 level in acute phase of HFRS was significantly higher in patients than that in healthy controls (P<0.0001) and the sCD100 level declined in convalescent phase. Multivariate model analysis showed that platelet count, white blood cell count, serum creatinine level and blood urea nitrogen level were associated with sCD100 levels and contributed independently to the elevated sCD100 levels. The expression of membrane CD100 on PBMCs decreased in the acute phase of HFRS patients compared with that of the normal controls and recovered in the convalescent phase. Conclusions We reported the elevated level of plasma sCD100 in HFRS patients and the elevated level might be a result from the shedding of membrane CD100 on PBMC. The elevated level of sCD100 was associated with disease severity, suggesting that sCD100 might be a cause or a consequence of progression of HFRS. The underlying mechanisms should be explored further.

Abstract
Objectives Urokinase-type plasminogen activator receptor is a multifunctional glycoprotein, the expression of which is increased during inflammation. It is known to bind to β3-integrins, which are elementary for the cellular entry of hantaviruses. Plasma soluble form of the receptor (suPAR) levels were evaluated as a predictor of severe Puumala hantavirus (PUUV) infection and as a possible factor involved in the pathogenesis of the disease. Design A single-centre prospective cohort study. Subjects and Methods Plasma suPAR levels were measured twice during the acute phase and once during the convalescence in 97 patients with serologically confirmed acute PUUV infection using a commercial enzyme-linked immunosorbent assay (ELISA). Results The plasma suPAR levels were significantly higher during the acute phase compared to the control values after the hospitalization (median 8.7 ng/ml, range 4.0–18.2 ng/ml vs. median 4.7 ng/ml, range 2.4–12.2 ng/ml, P<0.001). The maximum suPAR levels correlated with several variables reflecting the severity of the disease. There was a positive correlation with maximum leukocyte count (r = 0.475, p<0.001), maximum plasma creatinine concentration (r = 0.378, p<0.001), change in weight during the hospitalization (r = 0.406, p<0.001) and the length of hospitalization (r = 0.325, p = 0.001), and an inverse correlation with minimum platelet count (r = −0.325, p = 0.001) and minimum hematocrit (r = −0.369, p<0.001). Conclusion Plasma suPAR values are markedly increased during acute PUUV infection and associate with the severity of the disease. The overexpression of suPAR possibly activates β3-integrin in PUUV infection, and thus might be involved in the pathogenesis of the disease.

Abstract
Background Hematological abnormalities often occur several days before kidney injury in patients with hemorrhagic fever with renal syndrome (HFRS). We aimed to investigate the prevalence and prognostic value of the early hematological markers in patients with HFRS caused by Hantaan virus (HTNV) infection. Methods In a retrospective cohort study, we analyzed the case records of 112 patients with acute HTNV infection and evaluated the hematological markers for early prediction and risk stratification of HFRS patients with acute kidney injury (AKI). Results Of 112 patients analyzed, 66 (59%) developed severe AKI, defined as either receipt of acute dialysis or increased serum creatinine ≥354 µmol/L. The prognostic accuracy of hematological markers, as quantified by the area under the receiver-operating-characteristic curve (AUC), was highest with the nadir platelet count (AUC, 0.89; 95% CI, 0.83–0.95), as compared with the admission platelet count (AUC, 0.84; 95% CI, 0.77–0.92), and the admission and peak leukocyte counts. The nadir platelet count correlated moderately with the levels of peak blood urea nitrogen (r = –0.616) and serum creatinine (r = –0.589), the length of hospital stay (r = –0.599), and the number of dialysis sessions that each patient received during hospital stay (r = –0.625). By multivariate analysis, decreased nadir platelet count remained independently associated with the development of severe AKI (odds ratio, 27.57; 95% CI, 6.96–109.16; P<0.0001). Conclusions Thrombocytopenia, rather than leukocytosis, is independently associated with subsequent severe AKI among patients with acute HTNV infection.

Abstract
The study was organized to determine the diagnostic value of concentration of blood serum alveo-mucin as a marker of lesion of lung tissue in patients with community-acquired pneumonia and hemorrhagic fever with renal syndrome. The sampling included 86 patients with community-acquired pneumonia and 97 patients with hemorrhagic fever with renal syndrome. The patients with community-acquired pneumonia were divided in three groups according severity of disease course: slight form, medium-severe form and severe form of disease. The group of patients with medium-severe form of hemorrhagic fever with renal syndrome was divided on two groups depending on clinical roentgenologic pattern: with and without pathology of lungs. The high concentration of alveomucin at the day of hospitalization is typical for patients both with community-acquired pneumonia and with roentgenologically approved lungs affection in case of hemorrhagic fever with renal syndrome in comparison with patients with hemorrhagic fever with renal syndrome without affection of lung tissue (p=0.046). The concentration of alveomucin higher than 47.2 U/ml is established in 86% of patients with community-acquired pneumonia and affection of lung in case of hemorrhagic fever with renal syndrome and in 12% of patients with hemorrhagic fever with renal syndrome without affection of lungs (chi2=0.58 with Yeats equalization, p=0.44).

Abstract
In Scandinavia Puumala hantavirus causes nephropathia epidemica (NE), characterised by an acute debut of fever, headache, increasing back and abdominal pain, thrombocytopenia, increasing azotemia parameters, as well as microscopic haematuria and mild proteinuria. In some cases transitory myopia can be found. The diagnosis is made with a relevant clinical history and serology, and in most cases a kidney biopsy is not necessary. There is a risk of missing cases of NE as in this case, where a couple became infected by Puumala Hantavirus in a high-risk area but became ill in an area with a low prevalence.

Abstract
The article considers the results of analysis of serum alveomucin levels in 97 patients with hemorrhagic fever with renal syndrome depending on the form and period of disease. It is demonstrated that in patients with hemorrhagic fever with renal syndrome and clinical radiologic symptoms of lung affection already in initial period of disease the level of serum alveomucin is reliably higher than in the control group and the group of patients with hemorrhagic fever with renal syndrome and without lung affection. The correlation analysis revealed the reverse dependence between the level of alveomucin and arterial blood saturation with oxygen in patients with hemorrhagic fever with renal syndrome and disease form of medium severity.

Abstract
The goal of this work was to determine a correlation between the VE-cadherin and circulating endothelial cells (CECs) blood levels at hemorrhagic fever with renal syndrome (HFRS) of different severity and research association between the VE-cadherin gene c. 1550T>C missense mutation and HRFS severity. Significant decreasing of the VE-cadherin and increasing of CECs blood levels in the course of the disease in all studied groups was established. Most prominent changes were found at severe type with complications. There was found a strong negative correlation between these two indexes. There was significant high frequency of homozygotic genotype *T/*T at severe type with complications. It was concluded that there was increased endothelium desquamation due to the VE-cadherin internalization at moderate and severe uncomplicated types of HFRS and as a result ofVE-cadherin gene c. 1550T>C missense mutation at severe type with complications.

Abstract
The aim of study was to determine the probable sources of circulating endothelial cells (CECs) and establish the role of both VE-cadherin and vascular endothelial growth factor (VEGF) in molecular mechanism of endothelium desquamation using the hemorrhagic fever with renal syndrome as the model of endothelium injury. Autopsy pieces of kidney, liver, lung, brain, stomach and myocardium taken from 10 patients were studied histologically. Quantitative measurement of CECs was performed by the method developed by J. Hladovec (1978). Blood levels of VE-cadherin and VEGF were determined by ELISA method. Predominant sources CECs were found to be macro- and microvessels of kidney, liver, lung, brain, gastric mucous membrane, myocardium and, possibly - brain vessels. One of the molecular mechanism of endothelium desquamation is VEGF-stimulated internalization of VE-cadherin.

Abstract
Respiratory burst of neutrophils was studied in 40 serologically verified patients with hemorrhagic fever with renal syndrome (HFRS) using luminol-dependent chemiluminescence (CL). Markedly increased CL has been demonstrated since the first days of the illness in all investigated patients. The level of CL was much enhanced during initial, oliguric, polyuric stages and convalescence. In a case of HFRS complicated by shock CL was approximately 100-fold higher than in healthy controls. It is suggested that neutrophils have an important role in the pathogenesis of HFRS.

Abstract
The purpose of the study was to assess the incidence, type and dynamics of electrocardiography (ECG) alterations in patients with haemorrhagic fever with renal syndrome (HFRS) according to different stages of the disease. 79 patients hospitalized at the University Hospital for Infectious Diseases in Zagreb during the large HFRS outbreak in Croatia in 2002 were retrospectively analysed. HFRS diagnosis was confirmed by enzyme-linked immunosorbent assay. A 12-lead resting ECG was obtained. 30 (38%) patients had abnormal ECG findings, most frequently in the oliguric stage. Increased levels of urea and creatinine were observed in all patients with abnormal ECG, along with abnormal chest X-ray in nearly 50% of cases. Sinus tachycardia was the most frequent ECG disorder in the febrile stage, and bradycardia in the oliguric stage. During the course of disease, some other ECG disorders were recorded: bundle branch conduction defects, non-specific ventricular repolarization disturbances, supraventricular and ventricular extrasystoles, prolonged QT interval, low voltage of the QRS complexes in standard limb leads, atrioventricular block first-degree, and atrial fibrillation. Myocarditis was present in 3 patients. In conclusion, abnormal ECG was found in more than one-third of HFRS patients with the most common findings during the oliguric stage. All ECG changes were transient.

Abstract
AIM To establish a flow microbeads assay (FMA) to examine the level of hemorrhagic fever with renal syndrome virus (HFRS V.) specific IgM, IgG and cytokines in HFRS patients. METHODS Serum samples from 28 cases of HFRS and 20 healthy controls were studied. Serum levels of anti-HFRS V. antibodies were qualified and inflammatory cytokines IL-6 and TNF-alpha were quantified by FMA. The results were compared with the results by ELISA. RESULTS FMA showed that the positivity rates for anti-HFRS V. IgM and IgG were 92.85% and 71.43%, respectively. None was detected positive in healthy control group. The serum level of IL-6 and TNF-alpha in HFRS group were (532.62+/-397.19) ng/L and (392.68+/-177.68)ng/L, respectively, which were significantly higher than that in healthy control group (38.77+/-20.32 ng/L and 15.91+/-6.91 ng/L, P<0.01). In contrast, ELISA showed that the positivity rates for anti-HFRS V. IgM and IgG were 71.43% and 50.00%, respectively. None was detected positive in healthy control group. The serum level of IL-6 and TNF-alpha in HFRS group were (256.46+/-102.51) ng/L ang (45.63+/-5.32) ng/L, respectively, which were significantly higher than that in healthy control group (53.80+/-19.21 ng/L and 5.81+/-3.58 ng/L, P<0.01). CONCLUSION A FMA method is established to monitor the immune response in HFRS patients, which has better sensitivity than ELISA, and thus provides a useful tool for study of HFRS.

Abstract
OBJECTIVE To observe the changes of the plasma pro-inflammatory cytokines levels in patients with hemorrhagic fever with renal syndrome (HFRS). METHODS Enzyme-linked immunosorbent assay (ELISA) was performed to detect the plasma pro-inflammatory cytokines levels of 22 HFRS patients (9 mild cases and 13 moderate cases) 1, 4, and 12 weeks after they were diagnosed. Sixteen healthy blood donors were recruited as control group. RESULTS The levels of interleukin (IL)-1beta, IL-6, IL-10, tumor necrosis factor (TNF)-alpha, and IL-8 in HFRS patients were significantly higher than those in control group 1 week after they were diagnosed (all P < 0.01). The levels of IL-6 and TNF-alpha in HFRS patients returned to the normal levels four weeks after the diagnosis, while those of IL-1beta, IL-8, and IL-10 remained significantly higher than those in control group 12 weeks after the diagnosis (all P < 0.01). The IL-8 and IL-10 levels in mild HFRS patients were significantly higher than those in moderate HFRS patients at the same period (all P < 0.05). CONCLUSION Abnormal expressions and secretion of pro-inflammatory cytokines occurs during the disease course of HFRS.

Abstract
The essence of studies was that the disease is simulated in 12-day albino mice subcutaneously infected with Hantaan virus, strain 76-118 in a dose of 10 LD50. As an efficiency index, the study of drugs uses major (death protection coefficient, mean animal lifetime) and auxiliary (virological: pathogen accumulation in the brain tissues of deceased animals) parameters, biochemical (the levels of creatinine, urea, alanine aminotransferase, aspartate aminotransferase, malonic dialdehyde), hematological (count of leukocytes, leukogram) ones; as well as interferon status (the levels of circulatory interferon, leukocytic production of alpha- and gamma-interferons). The procedure for simulating the disease caused by Hantaan virus on an experimental animal is used to choose effective drugs against the pathogen of hemorrhagic nephrosonephritis.

Abstract
OBJECTIVE Five yeast-expressed recombination nucleotide proteins of European hantaviruses were prepared as coated antigens to detect hantavirus-specific antibodies in sera from hemorrhagic fever with renal syndromes (HFRS) in Hubei province, through ELISA assay. The relativity among hantaviruses prevailing in different areas was investigated. METHODS 34 pairs of acute/convalescent serum samples were collected from HFRS patients in Hubei during 1985-1989 and 1996-2000. ELISA assay was performed to detect the reactivity of these sera to different hantavirus-recombinant nucleocapsid proteins (HV-rNP) which were derived from puumala virus (PUUV), dobrava virus (DOBV) while using hantaan virus (HTNV) to serve as control. Qualitative results were used to analyze the detection rate and thequantitative results of optical density values were used to investigate the antibodies' level and the changes. RESULTS The detective efficiency of rNP against IgG antibody in samples was as follows: HTNV-rNP > DOBV-rNP > PUUV-rNP. As to the detection of IgA, it was: DOBV-rNP > HTNV-rNP > PUUV-rNP. However, there was no difference between DOBV-rNP and HTNV-rNP when the hantavirus-specific IgM was detected. PUUV-rNP showed a very weak reactivity to all the antibodies in samples, but 3-pair samples reacted strongly to all the three subtype-rNP of PUUV. Results from quantitative analysis revealed that there was a relative higher level of IgM and IgA in acute phase sera. No significant difference between IgM and IgA levels was found and the level of IgG was low. A high level of IgA was detected in convalescent sera. Moreover, the level of IgA and IgG significantly increased with the progress of the disease. CONCLUSION DOBV-rNP had a high detective efficiency to serum samples from HFRS patients in Hubei. HV-specific IgA was kept on a high level in acute and convalescent phases and had important implications for the surveillance of HFRS. Also, it is assumed that PUUV and DOBV might have existed in Hubei province.

Abstract
Hemorrhagic fever with renal syndrome (HFRS) is a significant public health problem with an increasing incidence in Beijing, China (report of disease surveillance from the Center for Disease Control and Prevention of Beijing, China). Hantaviruses were detected using RT-PCR method in blood samples of HFRS patients and lung tissues of rodents captured in Beijing. Phylogenetic analyses of 724bp partial S segment of the hantavirus gene showed that the detected Seoul virus (SEOV) fell into three different lineages, two of which circulated in Beijing. A nucleotide sequence identity of 99.7% for one of the cases of HFRS--the human- and Rattus norvegicus-originated SEOV sequences--had only two silent substitutions, suggesting genetic analysis is an essential tool for "case-investigation."

Abstract
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.

Abstract
OBJECTIVE Patients with typical clinical manifestations of Hemorrhagic fever with renal syndrome (HFRS) are becoming fewer. We conducted analysis on clinical features of HFRS in order to reduce the mistakes in diagnosis. METHODS 64 patients were diagnosed as HFRS during May, 2000 to June, 2006 in our hospital. All the patients' serological tests (HFRS-NP-specific IgM, IgG antibody) by ELISA method were positive. We collected their clinical manifestations and test results. SPSS 12.0 was used in our statistical analysis. RESULTS Among the 64 patients, 71.6% of all the cases occurred from Feb. to June. Most of patients were admitted to the hospital with untypical manifestation. Only 30.6% patients appeared headache, lumbago, and pain of orbital cavity. 32.8% patients had obviously signs of injection and hemorrhage. However, there were 90.6% patients with headache and 84.4% patients with nausea or vomit. Hypotensive or oliguric phases were absent in 56.3% patients. There were only 31.3% patients with all five stages. Thrombocytopenia (79.7%) and heavy proteinuria (71.9%) were common. But 54.7% of patients shown normal or even decreased white blood cell count. Only 2/3 of patients had elevated serum creatinine (Cr). Liver involved was common showing as elevated aminotransferase. ALT level was not always parallel to Cr level. There was an opposite trend between them. CONCLUSION We must recognized the untypical manifestations of HFRS. Further study focus on pathogenesis was useful for diagnosis and therapy.

Abstract
OBJECTIVE To develop and improve a MacELISA method for the early diagnosis of hemorrhagic fever with renal syndrome (HFRS) with simplified operation procedure. METHODS The nucleic proteins of hantavirus were labeled with horse raddish peroxidase (HRP) and used as detection antigens. A two-step MacELISA based HRP conjugated antigen was established and the detection sensitivity and specificity were compared with commonly used three-step MacELISA. RESULTS This method could be used to detect hantanvirus specific IgM with high sensitivity and specificity from human patient serum. There was not significant difference from commonly used three-step MacELISA and the sensitivity and specificity were 100%. CONCLUSION This method is simple, sensitive and rapid in operation, and therefore could be used for the early diagnosis of HFRS.

Abstract
Twenty-six patients with hemorrhagic fever with renal syndrome (HFRS) were revealed as a result of serological examination of 582 patients with fever living around Sochi town. Etiologic role of Dobrava virus subtype as the cause of HFRS was assessed by immunofluorescent and ELISA assays, and neutralization test. The principal host of this virus and source of infection for humans is Caucasian forest mouse Apodemus ponticus. HFRS morbidity was sporadic and not dependent from patients' occupation and season. Comparative analysis of clinical and laboratory data from HFRS cases caused by DOB/Sochi and DOB/Lipetsk subspecies, as well as Puumala virus showed higher proportion of severe forms of disease in patients with HFRS from Sochi.

Abstract
OBJECTIVE To observe the curative effect of oxymatrine to cure hemorrhagic fever with renal syndrome. METHODS Randomly divide 418 patients suffering from hemorrhagic fever with renal syndrome into a treatment group and a control group, use oxymatrine to give an intravenous drip to the patients in the treatment group, one time a day, each time 600 mg, lasting for 7 days as one period of treatment and meanwhile take a traditional equilibrium salt treatment for the patients in the control group. Observe the change of the illness in both groups and occurrence of complications, dynamically test the magnitude of serum urination-regulated protein (THP) and beta(2) microglobulin (beta(2)M) of the patients, in the meantime observe the change in magnitude of serum white blood cell medium 15 (IL-15) and soluble intercellular adhesion molecules (sICAM-1). RESULTS Shorten the course of the disease of the patients in the oxymatrine treatment group, make an improvement after the recovery and obviously reduce the magnitude of serum urination-regulated protein (THP) and beta(2) microglobulin and show a striking difference in magnitude of serum IL-15 and sICAM-1 after the treatment compared with that of the patients in the control group. CONCLUSION Oxymatrine has a certainly true curative effect to hemorrhagic fever with renal syndrome and worth of furthering its widespread use in clinics.

Abstract
Hemorrhagic fever with renal syndrome and hantavirus pulmonary syndrome are two diseases caused by hantaviruses. Capillary leakage is a hallmark of hantavirus infection. Pathogenic hantaviruses are not cytotoxic, but elevated levels of serum lactate dehydrogenase (LDH), indicative of cellular damage, are observed in patients. We report increased levels of serum perforin, granzyme B, and the epithelial cell apoptosis marker caspase-cleaved cytokeratin-18 during Puumala hantavirus infection. Significant correlation was observed between the levels of LDH and perforin and the levels of LDH and caspase-cleaved cytokeratin-18, suggesting that tissue damage is due to an immune reaction and that epithelial apoptosis contributed significantly to the damage.

Abstract
The expression of the apoptosis-inducing ligands, TNF-alpha, FasL and TRAIL on peripheral blood mononuclear cells (PBMC) and the levels of their soluble form (TNF-alpha, sFasL and sTRAIL) in plasma from 40 hemorrhagic fever with renal syndrome (HFRS) patients as well as 26 healthy blood donors were determined by flow cytometry (FCM) analysis and sandwich ELISA, respectively. The status of Th1, Th2, Tc1 and Tc2 subsets in PBMC was evaluated by intracellular cytokine staining and FCM. Compared to controls, the expression of membrane bound FasL and TRAIL was up-regulated on surface of PBMC isolated from the HFRS patients, particularly on CD8+ T lymphocytes. The levels of TNF-alpha, sFasL and sTRAIL in plasma from the HFRS patients in the acute phase increase 4.7-fold, 6.0-fold and 1.8-fold, respectively, over those from the healthy donors. The percentage of Th1, Tc1 and Tc2 subsets in PBMC from the patients also increased significantly compared with those from healthy donors. These results indicate that dynamic changes occurred in both the membrane bound and soluble forms of apoptosis-inducing ligands (FasL, TRAIL and TNF-alpha) and proportions of Th1 and CTL in HFRS patients increased. Both factors may play an important role in the etiology of Hantaan virus infection in humans.

Abstract
BACKGROUND To further probe into the role of CD178 in the pathogenesis of hemorrhagic fever with renal syndrome (HFRS). METHODS The expression of CD178 and HLA-DR on T cell subsets in peripheral blood of patients with HFRS and their dynamic changes were detected by Flow cytometry. RESULTS CD4+ CD178+ and CD8+ CD178+ T lymphocytes both in fever and polyuria phases were significantly higher than those in normal controls, while there was no significant difference between the both phases of HFRS (P > 0.05). CD178 expression on CD4+ HLA-DR+ and CD8+ HLA-DR+ T lymphocytes were significantly higher than those in normal controls (P < 0.05, P < 0.01, P < 0.001, P < 0.001), while there was no significant difference between CD4+ HLA-DR+ and CD8+ HLA-DR+ T lymphocytes (P > 0.05). CONCLUSION CD178 was expressed on both CD4+ and CD8+ T cell subsets, but mainly on CD8+ T cell subsets both in early stage and in later stage in the pathogenesis of HFRS. Cytotoxic T lymphocyte (CTL) might kill target cells infected by hantavirus (HV) and eliminate HV via cell apoptosis mediated by CD178 in early stage of HFRS. In later stage of HFRS, CD178 might reduce antigen-specific T lymphocytes by activation induced cell death (AICD) and help to maintain the homeostasis of immune system.

Abstract
OBJECTIVE To study the molecular epidemiological characteristics of hantavirus seen during 2000-2003 in Qingdao region of Shandong province. METHODS Sera were collected from 64 patients with hemorrhagic fever with renal syndrome (HFRS) and viral RNA was extracted from the sera. HTN and SEO universal primers were designed as outer primers and HTN and SEO specific primers as inner primers. G1 gene region of M segment from hantavirus was amplified by using RT-nest-PCR for sequencing. The data of nucleotide sequences were analyzed by DNA star software. RESULTS Six cases were positive by HTN specific primer of total cases (9%); 25 of 64 cases by SEO specific primer (39%); total positive rate was 48%. In general, SEO type was a prevalent type of hantavirus in Qingdao region. The variation of the nucleotide sequences among SEO viruses (nucleotide sequence divergence ranged from 0.3% approximately 8.9%) was lower than that among HTN type (nucleotide sequence divergence ranged from 2.6% approximately 11.2% ). CONCLUSION Majority of hantavirus found in Qingdao region belonged to SEO type and still a few strains belonged to HTN type. Most of the HTN viruses were detected in Jiaonan county.

Abstract
AIM To examine the frequency and distribution of hematologic and biochemical laboratory findings in 94 patients with hemorrhagic fever with renal syndrome (HFRS) in the epidemic year 2002. PATIENTS AND METHODS The following laboratory findings were retrospectively analyzed: erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), hemoglobin, hematocrit, leukocyte count and differential percentage (segmented neutrophils, band neutrophils, atypical lymphocytes), platelet count, coagulation tests, blood urea nitrogen (BUN), creatinine, urine, potassium, bilirubin (BIL), aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyltransferase (GT), alkaline phosphatase (ALP), and serum protein electrophoresis. The study included 94 HFRS patients treated at the Dr Fran Mihaljević University Hospital for Infectious Diseases in Zagreb during 2002. RESULTS ESR increase, mostly mild to moderate, was found in 86.2% of study patients. Increased CRP was recorded in 98.9% of study patients, however, one-fourth had CRP higher than 100 mg/L. Leukocytosis was recorded in 38.3% (10.1 +/- 4.2 x 10(9)/L), thrombocytopenia in 89.4% patients (68.2 +/- 48.3 x 10(9)/L), and severe thrombocytopenia (x 10(9)/L) in six patients. Three patients had abnormal coagulation tests. Increased values of BUN and creatinine were recorded in more than a half of patients, while only four patients had mild hyperkalemia. Only three patinets required hemodialysis. Mildly to moderately increased values of aminotransferases (AST, ALT, GT) were observed in more than 2/3; hypoalbuminaemia in nearly 1/3, and elevated alpha-2 fraction in more than 2/3 of patients. The majority of patients had pathologic urine findings. First laboratory abnormalities were usually found between day 5 and 7 of the disease (increased CRP level, thrombocytopenia, leukocytosis, and elevation of hemoglobin and hematocrit). Biochemical abnormalities(elevation of cratinine and urea, increased levels of aminotransferases) usually occurred at the beginning of the second week, and ESR increase in the second week of disease. CONCLUSION The majority of our patients had laboratory findings characteristic of HFRS. Thrombocytopenia and increased level of CRP were the most common laboratory findings during the first week of the disease. Renal and liver impairment occurred at the beginning of the second week of the disease.

Abstract
The subjects of the study--patients with severe hemorrhagic fever with renal syndrome--were divided into two groups: those who were on hemodialysis, and those who were not. The study included evaluation of the phospholipid spectrum of erythrocyte membranes in the acute period and during recovery. The results revealed conformational shifts in the structure of the bilipid membrane layer, which were maximal during the acute phase of the disease, as well as less prominent and varied changes in the phospholipid spectrum during recovery. This allows determination of the terms of rehabilitation of the patients and substantiates administration of membrane stabilizers as a part of complex therapy of residual syndrome.
