Abstract
Hypopituitarism is a relatively rare complication of hemorrhagic fever with renal syndrome. However, almost all available reported cases were total anterior pituitary hypofunction, isolated growth-hormone deficiency, or isolated gonadotropin deficiency. Here, we firstly describe a patient with partial hypopituitarism with ACTH deficiency as the main manifestation as a complication of hemorrhagic fever with renal syndrome.

Abstract
RATIONALE Hemorrhagic fever with renal syndrome (HFRS) is a common infectious disease in China. As a complication of post-Hantavirus infection, Guillain-Barre syndrome (GBS) was rarely previously reported. Here, we described a case of acute inflammatory demyelinative polyradiculoneuropathy secondary to Hantavirus infection in spring of 2023. We also made a summary of the clinical features from previous reported cases. PATIENT CONCERNS A young male patient complained a fever with headache, who was subsequently diagnosed with HFRS with positive serum Hantavirus antibody IgM. Two weeks later, he presented sustained back pain, obvious numbness located in 4 extremities, chest and abdomen, facial dyskinesia and 4 extremities muscle weakness. DIAGNOSIS, INTERVENTIONS, AND OUTCOMES He was rapidly diagnosed with GBS by typical cerebrospinal fluid change and the electromyography examination presentation, which was verified associated with hantavirus infection. He was treated with intravenous immunoglobulin infusion followed by rehabilitation treatment. He got a complete recovery within 4 months after disease onset. LESSONS GBS was an uncommon manifestation of Hantavirus infection. GBS should be considered when acute limb weakness happens in cases with HFRS. A multidisciplinary team could make a rapid diagnosis and optimal treatment when nervous system disorders occurred.

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), carried and spread by the bank vole (Myodes glareolus), causes a mild form of hemorrhagic fever with renal syndrome (HFRS) called nephropathia epidemica (NE). Acute high fever, acute kidney injury (AKI), thrombocytopenia, and hematuria are typical features of this syndrome. In addition, headache, blurred vision, insomnia, vertigo, and nausea are commonly associated with the disease. This review explores the mechanisms and presentations of ocular and central nervous system involvement in acute NE.

Abstract
Puumala virus (PUUV) is the most common hantavirus in Europe. It is known to cause nephropathia epidemica, which is considered a mild type of hemorrhagic fever with renal syndrome. However, it does not only involve the kidneys and is rarely accompanied by symptomatic hemorrhage. We review the imaging abnormalities caused by PUUV infection, from head to pelvis, emphasizing the broad spectrum of possible findings and bringing further support to a previously suggested denomination "Hantavirus disease" that would encompass all clinical manifestations. Although non-specific, knowledge of radiological appearances is useful to support clinically suspected PUUV infection, before confirmation by serology.

Abstract
Several case reports have described hypopituitarism following orthohantavirus infection, mostly following Puumala virus. The pathogenesis of this seemingly rare complication of orthohantavirus infection remains unknown. This review explores the possible pathophysiological mechanisms of pituitary damage due to orthohantavirus infection. In only three out of the 28 reported cases, hypopituitarism was detected during active infection. In the remaining cases, detection of pituitary damage was delayed, varying from two months up to thirteen months post-infection. In these cases, hypopituitarism remained undetected during the acute phase of infection or only occurred weeks to months post infection. Both ischemic and hemorrhagic damage of the pituitary gland have been detected in radiographic imaging and post-mortem studies in the studied case reports series. Ischemic damage could be caused by hypotension and/or vasospasms during the acute phase of hemorrhagic fever with renal syndrome (HFRS) while hemorrhage could be caused by thrombocytopenia, thrombopathy, and other known causes of coagulation disorders during orthohantavirus infection. Also, hypophysitis due to the presence of auto-antibodies have been suggested in the literature. In conclusion, a significant number of case reports and series describe hypopituitarism after orthohantavirus infection. In most cases hypopituitarism was diagnosed with a delay and therefore could very well be underreported. Clinicians should be aware of this potential endocrine complication, with substantial morbidity, and if unrecognized, significant mortality.

Abstract
Background We describe a case of Guillain-Barre syndrome (GBS) associated with hemorrhagic fever with renal syndrome. To our knowledge, only five cases of GBS associated with Hantavirus infection have been reported so far. Case presentations A 62-year-old man presented intermittent fever, chill and oliguria. According to remarkable leukocytosis, atypical lymphocytes, thrombocytopenia and former dwelling in hemorrhagic fever-endemic area, he was suspected as hemorrhagic fever with renal syndromeand certified with positive Hantavirus IgG. Later, the patient had symmetrical flaccid paralysis of all extremities. Electromyography showed peripheral nerve injury (mainly in axon). The patient was diagnosed as having acute motor sensory axonal neuropathy (AMSAN). After immunoglobulin infusion, patient showed progressive recovery and was transferred 3 weeks after his first admission to a rehabilitation center. Conclusions Our case was the 6th reported case of GBS associated with hemorrhagic fever with renal syndrome. Moreover, we for the first time classified the subtype of GBS (AMSAN) based on the electrophysiology characteristics. GBS should be suspected in patients who are already diagnosed as hemorrhagic fever with renal syndrome when delayed symmetrical limb paralysis occurs. Until recent now, GBS was only reported in hemorrhagic fever patients in Europe and Asia, which termed as hemorrhagic fever with renal syndrome.

Abstract
INTRODUCTION Chronic inflammatory demyelinating polyneuropathy (CIDP) is an acquired autoimmune disorder with progressive weakness. Acute-onset CIDP resembles Guillain-Barre syndrome (GBS), a rapidly progressive disorder, and follows a chronic course. To our knowledge, no case of acute-onset CIDP in hantavirus and hepatitis B virus (HBV) coinfection has been reported previously. CLINICAL FINDINGS We report a case of acute-onset CIDP that was initially diagnosed as GBS. DIAGNOSES A 44-year-old male logger complained of acute quadriplegia and dyspnea. Mechanical ventilation was initiated. He was an HBV carrier with mild elevation of hepatic enzyme, and positive for hantavirus antibody. He was diagnosed with GBS and immunoglobulin therapy was administered. INTERVENTIONS After 8 months, quadriplegia and hypesthesia recurred. Immunoglobulin therapy at this time had no effect, but steroid therapy had some effect. OUTCOMES A diagnosis of CIDP was made. After 2 months, severe extremity pain and dyspnea developed again, and steroid pulse therapy was initiated. CONCLUSION Besides GBS, acute-onset CIDP can occur with hantavirus and HBV coinfection. Patients with this coinfection in whom GBS has been initially diagnosed should be followed up for a long time, because of the possibility of relapse or deterioration, and acute-onset CIDP should always be considered.

Abstract
Puumala hantavirus (PUUV) infection causes nephropathia epidemica (NE), a relatively mild form of haemorrhagic fever with renal syndrome (HFRS). Hypophyseal haemorrhage and hypopituitarism have been described in case reports on patients with acute NE. Chronic hypopituitarism diagnosed months or years after the acute illness has also been reported, without any signs of a haemorrhagic aetiology. The mechanisms leading to the late-onset hormonal defects remain unknown. Here, we present a case of NE-associated autoimmune polyendocrinopathy and hypopituitarism presumably due to autoimmune hypophysitis. Thyroid peroxidase antibody seroconversion occurred between 6 and 12 months, and ovarian as well as glutamate decarboxylase antibodies were found 18 months after acute NE. Brain MRI revealed an atrophic adenohypophysis with a heterogeneous, low signal intensity compatible with a sequela of hypophysitis. The patient developed central (or mixed central and peripheral) hypothyroidism, hypogonadism and diabetes insipidus, all requiring hormonal replacement therapy. This case report suggests that late-onset hormonal defects after PUUV infection may develop by an autoimmune mechanism. This hypothesis needs to be confirmed by prospective studies with sufficient numbers of patients.

Abstract
OBJECTIVE Nephropathia epidemica (NE) is a haemorrhagic fever with renal syndrome (HFRS) caused by Puumala hantavirus (PUUV). Pituitary haemorrhage and hypopituitarism may complicate recovery from acute NE. DESIGN Forty-seven of our recent cohort of 58 NE patients volunteered to be re-examined in order to estimate the burden of hormonal deficiency 4 to 8 years after the acute illness. Two patients had suffered from pituitary haemorrhage, but many others exhibited pituitary oedema during their acute infection. In this study, we searched for symptoms of hormonal deficiency, performed hormonal laboratory screening, and most patients underwent pituitary MRI examination. RESULTS The pituitary size had diminished in all patients in whom MRI was performed (P < 0·001). One patient with acute phase haemorrhage had made a complete recovery while the other continued to require hormonal substitution. In addition, hormonal laboratory abnormalities were observed in nine other patients; these being attributable to several reasons, for example independent peripheral hormonal diseases, side effects of medication or other secondary causes such as obesity. None of them had signs of late-onset pituitary insufficiency caused by their previous NE. Health-related quality of life (mean and median 15D score) of patients was comparable to that of age-standardized general population. CONCLUSIONS None of our patients had developed obvious late-onset hypopituitarism despite of the fact that pituitary gland can be affected during acute NE. We recommend requesting a history of hantavirus infection whenever the possibility of pituitary dysfunction is suspected at least in patients originating from regions with high NE infection rate.

Abstract
We report the case of a 62-year-old man who developed Guillain-Barré syndrome (GBS) following Hantavirus infection. Only three similar cases have been described in the literature so far. GBS is an autoimmune disease characterized by progressive symmetrical weakness of lower limbs extending to upper limbs and face and low or absent tendon reflexes. Prompt diagnosis is mandatory as GBS is a potentially life threatening disorder and needs timely treatment to ensure fast recovery and fewer complications.

Abstract
Hypopituitarism often remains unrecognized due to subtle clinical manifestations. Anterior pituitary hormone deficiencies may present as isolated or multiple and may be transient or permanent. Traumatic brain injury (TBI) is recognized as a risk factor for hypopituitarism, most frequently presenting with isolated growth hormone deficiency (GHD). Data analysis shows that about 15% of patients with TBI have some degree of hypopituitarism which if not recognized may be mistakenly ascribed to persistent neurologic injury and cognitive impairment. Identification of predictors for hypopituitarism after TBI is important, one of them being the severity of TBI. The mechanisms involve lesions in the hypothalamic-pituitary axis and inflammatory changes in the central nervous system (CNS). With time, hypopituitarism after TBI may progress or reverse. Cranial irradiation is another important risk factor for hypopituitarism. Deficiencies in anterior pituitary hormone secretion (partial or complete) occur following radiation damage to the hypothalamic-pituitary region, the severity and frequency of which correlate with the total radiation dose delivered to the region and the length of follow-up. These radiation-induced hormone deficiencies are irreversible and progressive. Despite numerous case reports, the incidence of hypothalamic-pituitary dysfunction following infectious diseases of the CNS has been underestimated. Hypopituitarism usually relates to the severity of the disease, type of causative agent (bacterial, TBC, fungal, or viral) and primary localization of the infection. Unrecognized hypopituitarism may be misdiagnosed as postencephalitic syndrome, while the presence of a sellar mass with suprasellar extension may be misdiagnosed as pituitary macroadenoma in a patient with pituitary abscess which is potentially a life-threatening disease.

Abstract
Puumala virus (PUUV) causes an acute hemorrhagic fever with renal syndrome (HFRS), a zoonosis also called nephropathia epidemica (NE). The reservoir host of PUUV is the bank vole (Myodes glareolus). Herein we review the main clinical manifestations of NE, acute kidney injury, increased vascular permeability, coagulation abnormalities as well as pulmonary, cardiac, central nervous system and ocular manifestations of the disease. Several biomarkers of disease severity have recently been discovered: interleukin-6, pentraxin-3, C-reactive protein, indoleamine 2,3-dioxygenase, cell-free DNA, soluble urokinase-type plasminogen activator, GATA-3 and Mac-2 binding protein. The role of cytokines, vascular endothelial growth hormone, complement, bradykinin, cellular immune response and other mechanisms in the pathogenesis of NE as well as host genetic factors will be discussed. Finally therapeutic aspects and directions for further research will be handled.

Abstract
Hantaviruses (genus Hantavirus, family Bunyaviridae) are enveloped tri-segmented negative-stranded RNA viruses each carried by a specific rodent or insectivore host species. Several different hantaviruses known to infect humans circulate in Europe. The most common is Puumala (PUUV) carried by the bank vole; another two important, genetically closely related ones are Dobrava-Belgrade (DOBV) and Saaremaa viruses (SAAV) carried by Apodemus mice (species names follow the International Committee on Taxonomy of Viruses nomenclature). Of the two hantaviral diseases, hemorrhagic fever with renal syndrome (HFRS) and hantaviral cardiopulmonary syndrome, the European viruses cause only HFRS: DOBV with often severe symptoms and a high case fatality rate, and PUUV and SAAV more often mild disease. More than 10,000 HFRS cases are diagnosed annually in Europe and in increasing numbers. Whether this is because of increasing recognition by the medical community or due to environmental factors such as climate change, or both, is not known. Nevertheless, in large areas of Europe, the population has a considerable seroprevalence but only relatively few HFRS cases are reported. Moreover, no epidemiological data are available from many countries. We know now that cardiac, pulmonary, ocular and hormonal disorders are, besides renal changes, common during the acute stage of PUUV and DOBV infection. About 5% of hospitalized PUUV and 16%-48% of DOBV patients require dialysis and some prolonged intensive-care treatment. Although PUUV-HFRS has a low case fatality rate, complications and long-term hormonal, renal, and cardiovascular consequences commonly occur. No vaccine or specific therapy is in general use in Europe. We conclude that hantaviruses have a significant impact on public health in Europe.

Abstract
Background Our aim was to characterize clinical properties and laboratory parameters in patients with or without cerebrospinal fluid (CSF) findings suggestive of central nervous system (CNS) involvement, and especially those who developed serious CNS complications during acute nephropathia epidemica (NE) caused by Puumala hantavirus (PUUV) infection. Methods A prospective cohort of 40 patients with acute NE and no signs of major CNS complications was analyzed. In addition, 8 patients with major CNS complications associated with NE were characterized. We collected data of CNS symptoms, CSF analysis, brain magnetic resonance imaging (MRI) results, electroencephalography (EEG) recordings, kidney function, and a number of laboratory parameters. Selected patients were evaluated by an ophthalmologist. Results Patients with a positive CSF PUUV IgM finding or major CNS complications were more often males (p < 0.05) and they had higher plasma creatinine values (p < 0.001) compared to those with negative CSF PUUV IgM. The degree of tissue edema did not explain the CSF findings. Patients with major CNS complications were younger than those with negative CSF PUUV IgM finding (52.9 vs. 38.5 years, p < 0.05). Some patients developed permanent neurological and ophthalmological impairments. Conclusions CNS and ocular involvement during and after acute NE can cause permanent damage and these symptoms seem to be attributable to true infection of the CNS rather than increased tissue permeability. The possibility of this condition should be borne in mind especially in young male patients.

Abstract
BACKGROUND Viral hemorrhagic fevers (VHF) are considered to be a serious threat to public health worldwide with up to 100 million cases annually. The general hypothesis is that disseminated intravascular coagulation (DIC) is an important part of the pathogenesis. The study objectives were to study the variability of DIC in consecutive patients with acute hemorrhagic fever with renal syndrome (HFRS), and to evaluate if different established DIC-scores can be used as a prognostic marker for a more severe illness. METHOD AND FINDINGS In a prospective study 2006-2008, data from 106 patients with confirmed HFRS were analyzed and scored for the presence of DIC according to six different templates based on criteria from the International Society on Thrombosis and Haemostasis (ISTH). The DIC-scoring templates with a fibrinogen/CRP-ratio were most predictive, with predictions for moderate/severe illness (p<0.01) and bleeding of moderate/major importance (p<0.05). With these templates, 18.9-28.3% of the patients were diagnosed with DIC. CONCLUSIONS DIC was found in about one fourth of the patients and correlated with a more severe disease. This supports that DIC is an important part of the pathogenesis in HFRS. ISTH-scores including fibrinogen/CRP-ratio outperform models without. The high negative predictive value could be a valuable tool for the clinician. We also believe that our findings could be relevant for other VHFs.

Abstract
BACKGROUND Puumala hantavirus (PUUV) causes a hemorrhagic fever with renal syndrome (HFRS) also called nephropathia epidemica (NE). Recent case reports and retrospective studies suggest that NE may damage the pituitary gland. Based on these observations, our goal was to explore the nature of this complication prospectively. METHODS A total of 58 hospitalized patients with acute NE volunteered to participate. Central nervous system (CNS) symptoms were recorded, cerebrospinal fluid (CSF) samples were collected, human leukocyte antigen (HLA) haplotype was analyzed, brain magnetic resonance imaging (MRI) was acquired, and electroencephalography (EEG) was recorded. Patients with abnormal pituitary MRI finding were examined by an endocrinologist. RESULTS Most patients experienced CNS symptoms, and half of the CSF samples were positive for PUUV IgM, elevated protein level, or leukocyte count. CSF of patients negative for DR15(2)-DQ6 haplotype was less frequently affected. MRI revealed pituitary hemorrhage in two patients; these two patients suffered sudden loss of vision associated with headache, and they both developed hypopituitarism. Only one patient required long-term hormonal replacement therapy. CONCLUSION CNS-related symptoms and inflammation in the CSF are common in acute NE. Genetic properties of the host may predispose to CNS involvement. It does seem that pituitary injury and subsequent hormonal insufficiency may complicate the recovery.

Abstract
Previous reports have described panhypopituitarism associated with severe cases of hemorrhagic fever with renal syndrome (HFRS), but the prevalence of hormonal deficiencies after nephropathia epidemica (NE), a milder form of HFRS, has not been studied. This study was conducted in order to determine the prevalence of hormonal defects in patients with acute NE and during long-term follow-up. Fifty-four patients with serologically confirmed acute NE were examined by serum hormonal measurements during the acute NE, after 3 months, and after 1 to 10 (median 5) years. Thirty out of 54 (56%) patients had abnormalities of the gonadal and/or thyroid axis during the acute NE. After a median follow-up of 5 years, 9 (17%) patients were diagnosed with a chronic, overt hormonal deficit: hypopituitarism was found in five patients and primary hypothyroidism in five patients. In addition, chronic subclinical testicular failure was found in five men. High creatinine levels and inflammatory markers during NE were associated with the acute central hormone deficiencies, but not with the chronic deficiencies. Hormonal defects are common during acute NE and, surprisingly, many patients develop chronic hormonal deficiencies after NE. The occurrence of long-term hormonal defects cannot be predicted by the severity of acute NE.

Abstract
CONTEXT Hemorrhagic fever with renal syndrome (HFRS) caused by hantaviruses, is a severe systemic infection, with acute shock, vascular leakage, hypotension, and acute renal failure. Pituitary ischemia/infarction and necrosis are known causes of hypopituitarism, often remaining unrecognized due to subtle clinical manifestations. Cases of hypopituitarism after HFRS were previously only sporadically reported. OBJECTIVE The aim of this study was to determine, for the first time, the prevalence of hypopituitarism among HFRS survivors. SUBJECTS AND METHODS In 60 adults (aged 35.8+/-1.3 yr) who recovered from HFRS 3.7 +/- 0.5 yr ago (median 2 yr), assessment of serum T(4), free T(4), TSH, IGF-I, prolactin, cortisol, and testosterone (in males) was followed by insulin tolerance test and/or GHRH+GH-releasing peptide-6 stimulation tests. RESULTS Severe GH deficiency was confirmed in eight of 60 patients (13.3%): in five with multiple pituitary hormone deficiencies (MPHDs) and isolated in three. Thyroid axis deficiency was confirmed in five of 60 patients (8.3%), all with MPHD. Hypothalamus-pituitary-adrenal axis deficiency was observed in six of 60 (10.0%); in five with MPHD and isolated in one. Gonadal axis deficiency was confirmed in seven of 56 male subjects (12.5%): five with MPHD and isolated in two. Overall six patients (10.0%) had a single pituitary deficit (three GH, two gonadal, and one adrenal), and five (8.3%) had MPHD. The prevalence of patients having any endocrine deficiency was 18% (11 of 60). CONCLUSION A high prevalence of hypopituitarism after recovery from HFRS is identified, with magnetic resonance imaging revealing atrophic pituitary and empty sella. Awareness is raised to neuroendocrine consequences of HFRS because unrecognized hypopituitarism significantly affects the physical and psychological well-being.

Abstract
Puumala virus (PUUV) is the endemic hantavirus in northern Sweden and causes nephropathia epidemica (NE), a milder form of hemorrhagic fever with renal syndrome. There is a need for fast and reliable diagnostics to differentiate the disease from other infections. By aligning virus RNA sequences isolated from 11 different bank voles and one human patient, we designed a real-time reverse transcriptase (RT) PCR method for detection of PUUV RNA. The real-time RT-PCR assay showed linearity from 20 to 2 x 10(6) virus copies with a correlation coefficient above 0.98 to 0.99 for all experiments. The detection threshold for PUUV cDNA was two copies per reaction. A two-step qualitative RT-PCR to detect PUUV RNA showed 100% concordance with the real-time RT-PCR assay. PUUV RNA viremia was detected in 33 of 34 PUUV immunoglobulin M (IgM)-positive patients with typical clinical NE disease from the region of endemicity. One PUUV IgM-negative sample had PUUV RNA, and 4 days later, the patient was IgM positive. Of samples with indeterminate IgM, 43% were PUUV RNA positive. The kinetics of antibody titers and PUUV viremia were studied, and five of six NE patients displayed a decrease in PUUV viremia a few days after disease outbreak coupled with an increase in PUUV IgM and IgG. In one patient with continuously high PUUV RNA levels but low IgM and no IgG response, the infection was lethal. These findings demonstrated that real-time RT-PCR is a useful method for diagnosis of PUUV viremia and for detecting PUUV RNA at early time points, before the appearance of IgM antibodies.

Abstract
Hantaviruses are enveloped RNA viruses each carried by a specific rodent species. Three hantaviruses, Puumala, Dobrava, and Saaremaa viruses, are known to cause haemorrhagic fever with renal syndrome. In Europe. Puumala causes a generally mild disease, nephropathia epidemica, which presents most commonly with fever, headache, gastrointestinal symptoms, impaired renal function, and blurred vision, whereas Dobrava infections often also have haemorrhagic complications. There are few available data about the clinical picture of confirmed Saaremaa infections, but epidemiological evidence suggests that it is less pathogenic than Dobrava, and that Saaremaa infections are more similar to nephropathia epidemica caused by Puumala. Along with its rodent host, the bank vole (Clethrionomys glareolus), Puumala is reported throughout most of Europe (excluding the Mediterranean region), whereas Dobrava, carried by the yellow-necked mouse (Apodemus flavicollis), and Saaremaa, carried by the striped field mouse (Apodemus agrarius), are reported mainly in eastern and central Europe. The diagnosis of acute hantavirus infection is based on the detection of virus-specific IgM. Whereas Puumala is distinct, Dobrava and Saaremaa are genetically and antigenically very closely related and were previously thought to be variants of the same virus. Typing of a specific hantavirus infection requires neutralisation antibody assays or reverse transcriptase PCR and sequencing.

Abstract
Central nervous system (CNS) - related symptoms occur in haemorrhagic fever with renal syndrome (HFRS). To study the CNS and ophthalmic involvement in nephropathia epidemica (NE), the European type of HFRS, we included 26 patients in a prospective study. Most common CNS-related symptoms were headache (96%), insomnia (83%), vertigo (79%), nausea (79%), and vomiting (71%). Ophthalmic symptoms were reported by 82% of patients; 41% had photophobia and 50% had impaired vision. A transient loss of vision was recorded in one patient, who also had a generalized seizure. Minor white matter lesions were found in about half of the patients investigated with brain magnetic resonance imaging (MRI). Electroencephalography (EEG) showed severe alterations in only one patient, and slight and reversible patterns in another two patients. Neopterin, interleukin-6 and interferon-gamma levels in the cerebrospinal fluid (CSF) were elevated, which may indicate immune activation. However, we found no evidence of intrathecal NE virus replication. We conclude that CNS-related symptoms are common in NE, and transient ophthalmic involvement can be demonstrated in about half of the patients.

Abstract
Nephropathia epidemica (NE) caused by Puumala hantavirus is one type of hemorrhagic fever with renal syndrome (HFRS). There is considerable variability in the clinical severity of NE. Many infections are subclinical but the disease can even be fatal. We questioned whether the wide spectrum in the outcome of NE is dependent, on host-related immunological factors by determining the major histocompatibility complex markers (MHC) in 74 adult patients with NE. Patients with the most severe course of the disease had a very high frequency of HLA B8, C4A*Q0, and DRB1*0301 alleles. HLA B8 was found in all 7 (100%) patients with shock and in 9 of the 13 (69%) patients who required dialysis, versus in only 25 of 74 (34%) in the entire population, and in 14 of 93 (15%) controls. In addition, various other clinical findings pointing to a severe form of NE were found to be associated with these alleles. Interestingly, the same MHC alleles are risk factors for various autoimmune diseases. This is the first study where a certain HLA haplotype is found to be associated with the clinical course of an acute viral disease or acute nephritis.

Abstract
Four serologically confirmed fatal cases of nephropathia epidemica (NE), the mild form of hemorrhagic fever with renal syndrome (HFRS) are described. All the patients had disseminated intravascular coagulation. Autopsies revealed hemorrhage and necrotic areas of their pituitary glands, myocarditis, venous congestion and hemorrhage of the kidneys as well as pulmonary edema and hemorrhage of the lungs in all patients. This report provides new evidence that NE can be a fatal disease.

Abstract
An outbreak of an acute respiratory disease in the southwestern United States has led to the recognition of a new hantaviral illness. This report describes a unique spectrum of antemortem and postmortem pathological findings seen in a case series of nine surviving patients and 13 who died. Clinical, laboratory, and autopsy findings were derived from a consecutive series of individuals confirmed to have hantavirus pulmonary syndrome. Laboratory studies included chemical, hematological, and bone marrow analyses as well as flow cytometric and immunohistochemical phenotyping. Autopsy tissues were examined by routine histological stains, immunohistochemical methods, and transmission electron microscopy. The lung is the primary target organ in this illness. Pulmonary abnormalities include pleural effusions, alveolar edema and fibrin, and an interstitial mononuclear cell infiltrate. Large immunoblast type cells are seen in the lungs, blood, bone marrow, lymph nodes, liver, and spleen. A tetrad of hematological findings includes left-shifted neutrophilic leukocytosis, thrombocytopenia, hemoconcentration in severe cases, and circulating immunoblasts. In contrast to previously described nephropathic hantaviral syndromes, hantavirus pulmonary syndrome is characterized by a unique constellation of pulmonary, hematological, and reticuloendothelial pathological findings. The pulmonary findings are distinguishable from fatal adult respiratory distress syndrome. The data suggest a capillary leak syndrome restricted to the pulmonary circulation. Likewise, the hematological picture is unique and may be valuable in the rapid identification of cases for further diagnostic studies.

Abstract
The clinical picture of nephropathia epidemica (NE) among children is poorly understood. We made a retrospective analysis of 32 patients aged 4-15 years treated in hospital for serologically verified recent NE. The most common clinical findings were high fever (100%), nausea (81%), vomiting (72%), tenderness in the kidney area (63%), abdominal pains (59%) and headache (59%). A peculiar symptom of NE, transient visual abnormalities, was found in 25% of patients. Four children had clinical bleeding and 1 had encephalitis. 44% were transiently hypertensive. Renal function was impaired in 84%, proteinuria was present in 97%, hematuria in 73% and leukocyturia in 44%. Other common laboratory findings were thrombocytopenia (87%), leukocytosis (41%), elevated ERS (74%, up to 76 mm/h) and CRP level (89%, up to 97 mg/l), elevated liver enzymes (53%) and hypoalbuminemia (50%). No child needed dialysis therapy and all recovered. NE seems to be less severe in children than in adults.

Abstract
A total of 126 (99 males, 27 females) serologically confirmed hospital-treated adult cases of nephropathia epidemica (NE) were studied. The initial diagnosis suggested by the referring physician was correct in only 28%. Some rare clinical manifestations of NE were observed; acute myopericarditis in 3 patients and encephalitis in 1. Pulmonary involvement due to vascular congestion was observed in 16% and liver involvement in 34% of the patients. Thrombocytopenia was present in 75%, leukocytosis in 50% and anemia in 50%. Erythrocyte sedimentation rate (ESR) was 2-108 (mean 38) mm/h and C-reactive protein (CRP) 0-126 (mean 52) mg/l. Proteinuria was observed in 94%, hematuria in 58% and pyuria in 28%. Electrolyte abnormalities (hyponatremia, hypokalemia, hypocalcemia, hyperphosphatemia) were all common but rarely serious. Serum lipid changes caused by the acute infection and renal failure included very low total and HDL-cholesterol as well as high triglyceride levels. Renal function was transiently impaired in 94% of the patients and 7 needed transient dialysis therapy. All recovered.
