Abstract
Hepatitis C Virus (HCV), despite being a hepatotropic virus, is the causative agent of many systemic disorders, such as vasculitis, autoimmune diseases, lymphoproliferative disorders, and a broad spectrum of neurological and psychiatric manifestations. Although symptoms have been misdiagnosed or underdiagnosed, only recently, evidence of direct (inflammatory) or indirect (immune-mediated) HCV-dependent cerebral effects has been established. HCV infection can promote acute inflammatory response, pro-coagulative status and ischemic disorders, and neurodegeneration. These effects rely on cerebral HCV replication, possibly mediated by blood-brain barrier alterations. Further study is needed to better understand the HCV-related mechanisms of brain damage.

Disseminated inflammation of the central nervous system associated with acute hepatitis E: a case report. BMC Neurol 2020; 20:391. [PMID: 33109105 PMCID: PMC7590485 DOI: 10.1186/s12883-020-01952-5] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2020] [Accepted: 10/05/2020] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND Hepatitis E infection affects over 20 million people worldwide. Reports of neurological manifestations are largely limited to the peripheral nervous system. We report a middle-aged genotype 3c male patient with acute hepatitis E virus (HEV) infection and severe neurological deficits with evidence of multiple disseminated inflammatory lesions of the central nervous system. CASE PRESENTATION A 42-year-old male patient presented to our emergency department with musculoskeletal weakness, bladder and bowel retention, blurred vision and ascending hypoesthesia up to the level of T8. Serology showed elevated liver enzymes and positive IgM-titers of hepatitis E. Analysis of cerebrospinal fluid (CSF) showed mild pleocytosis and normal levels of glucose, lactate and protein. HEV-RNA-copies were detected in the CSF and stool. Within 3 days after admission the patient became paraplegic, had complete visual loss and absent pupillary reflexes. MRI showed inflammatory demyelination of the optic nerve sheaths, multiple subcortical brain regions and the spinal cord. Electrophysiology revealed axonal damage of the peroneal nerve on both sides with absent F-waves. Treatment was performed with methylprednisolone, two cycles of plasma exchange (PLEX), one cycle of intravenous immunoglobulins (IVIG) and ribavirin which was used off-label. Liver enzymes normalized after 1 week and serology was negative for HEV-RNA after 3 weeks. Follow-up MRI showed progressive demyelination and new leptomeningeal enhancement at the thoracic spine and cauda equina 4 weeks after admission. Four months later, after rehabilitation was completed, repeated MRI showed gliotic transformation of the spinal cord without signs of an active inflammation. Treatment with rituximab was initiated. The patient remained paraplegic and hypoesthesia had ascended up to T5. Nevertheless, he regained full vision. CONCLUSIONS Our case indicates a possible association of acute HEV infection with widespread disseminated central nervous system inflammation. Up to now, no specific drugs have been approved for the treatment of acute HEV infection. We treated our patient off-label with ribavirin and escalated immunomodulatory therapy considering clinical progression and the possibility of an autoimmune response targeting nerve cell structures. While response to treatment was rather limited in our case, detection of HEV in patients with acute neurological deficits might help optimize individual treatment strategies.

Abstract
Die chronische Hepatitis-C-Virus(HCV)-Infektion ist eine hochprävalente Systemerkrankung, die verschiedene neurologische Komplikationen verursachen kann. Es lassen sich HCV-assoziierte Symptome im zentralen und peripheren Nervensystem sowie der Muskulatur unterscheiden. Wichtige Pathomechanismen sind die HCV-assoziierte Autoimmunität (z. B. gemischte Kryoglobulinämie mit Polyneuropathie) und direkte Neurotoxizität (z. B. bei HCV-assoziierten kognitiven Defiziten). Die häufigsten neurologischen Komplikationen sind distal-symmetrische Polyneuropathien, Small-fiber-Neuropathien und kognitive Defizite. Die HCV-Infektion stellt außerdem einen Risikofaktor für ischämische und hämorrhagische Schlaganfälle sowie den Morbus Parkinson dar. Die frühe Identifikation und antivirale Behandlung HCV-positiver Patienten steht im Zentrum der Behandlung. Durch neue antivirale Therapien können >90 % der Patienten dauerhaft von der HCV-Infektion geheilt werden.

Abstract
INTRODUCTION Limited information is available describing the spectrum of neurological complications of cryoglobulinemia. METHODS Single center retrospective review of patients with neurologic symptoms and elevated serum cryoglobulins, with their potential association being classified as definite, possible, or unlikely using defined criteria. RESULTS Among 492 patients, 131 (87 classified as definite and 44 as possible) had neurologic symptoms associated with cryoglobulinemia. Common comorbidities included hepatitis C (N = 43), monoclonal gammopathy of undetermined significance (N = 20), Sjogren's syndrome (N = 17), membranoproliferative glomerulonephritis (N = 17), and systemic lupus erythematosus (N = 10). Features supporting an association between cryoglobulinemia and neurological symptoms were the presence of purpura (p < .001), positive rheumatoid factor (p = .001) and low C4 (p = .002). Common peripheral neurological diagnoses were symmetric polyneuropathy (N = 84), small fiber neuropathy (N = 25), and mononeuritis multiplex (N = 16). Central neurological manifestations were infrequent and included seizures (N = 3), posterior reversible encephalopathy syndrome (N = 2), intracerebral hemorrhage (N = 1), vasculitis (N = 1), rapidly progressive dementia (N = 1), lymphoma (N = 1), and myelitis/meningitis (N = 1). Treatments utilized included corticosteroids (N = 74), rituximab (N = 42), cyclophosphamide (N = 27), methotrexate, azathioprine, or mycophenolate mofetil (N = 28), anti-viral therapy (N = 20), plasmapheresis (N = 16), and intravenous immunoglobulin (N = 20). Neurologic symptoms associated with cryoglobulinemia remained stable or improved in 86% of patients. CONCLUSION This study describes a wide spectrum of patients with neurologic symptoms attributed to cryoglobulinemia and provides a framework to approach this challenging diagnosis.

Abstract
INTRODUCTION Chronic hepatitis C virus (HCV) infection has been associated with myriad extrahepatic manifestations, often resulting from aberrant immune responses. Among the most common immune-mediated manifestations of HCV infection, mixed cryoglobulinemia is the best known extra-hepatic complication. Areas covered: Here we review less common extrahepatic manifestations of HCV infection, with ascertained or presumed immune pathogenesis and the role of the new all oral direct-acting antiviral agents. Rheumatologic, dermatologic, ophthalmologic, renal, pulmonary, hematologic, cardiovascular, and neuropsychiatric manifestations of HCV infection have been considered. Expert commentary: Pathogenesis of HCV-induced aberrant immune responses resulting in peculiar clinical manifestations is not restricted to a single mechanism. A sound approach would therefore consider implementation of an etiologic treatment, through use of antiviral medications, to stop upstream in the pathogenic process all the immune mechanisms leading to hepatic and extrahepatic abnormalities. With the recent introduction of interferon-free, direct antiviral agents, capable of warranting cure for nearly all HCV-infected patients subjected to therapy, both common and uncommon extrahepatic manifestations of chronic hepatitis C are expected to no longer constitute a matter of comorbidity in the course of HCV infection.

Abstract
Nervous system involvement in Hepatitis C virus infection (HCV) has been associated to neuro-immunological deregulation, particularly in interferon-alpha treated patients. We present a case of optic and brainstem demyelinating disorder associated with aquaporin-4 (AQP4) antibodies. A 48 year-old woman, with previous diagnosis of non-treated hepatitis C, presented with a 10-year history of long-standing gait disturbance. Neurological examination disclosed a grade 4 spastic paraparesis, lower limb hyperreflexia, right positive Hoffmann sign, bilateral Babinski sign and spastic gait only possible with bilateral support. Spinal cord magnetic resonance imaging (MRI) was normal. Brain MRI showed an asymmetric, bilateral pontine and left mesencephalic hypersignal in T2 and FLAIR, with no gadolinium enhancement. Visual evoked potential revealed bilateral pre-chiasmatic conduction delay. Blood tests showed a positive anti-HCV antibody and a positive AQP4 antibody. Cerebrospinal fluid (CSF) analysis was normal, with no oligoclonal bands. The patient started intravenous (IV) methylprednisolone followed by oral prednisolone; simultaneously, interferon-alpha and ribavirin. There was a slight clinical improvement within the first weeks. There are 7 cases describing association between HCV infection and central nervous system (CNS) demyelination with positive AQP4 antibody, 4 patients under interferon-α. AQP4 antibodies should be tested in patients infected with HCV and CNS demyelination.

Abstract
Chronic infection with hepatitis C virus (HCV) is associated with a large spectrum of extrahepatic
manifestations (EHMs), mostly immunologic/rheumatologic in nature owing to B-cell proliferation and clonal expansion.
Neurological complications are thought to be immune-mediated or secondary to invasion of neural tissues by HCV, as
postulated in transverse myelitis and encephalopathic forms. Primarily axonal neuropathies, including sensorimotor
polyneuropathy, large or small fiber sensory neuropathy, motor polyneuropathy, mononeuritis, mononeuritis multiplex, or
overlapping syndrome, represent the most common neurological complications of chronic HCV infection. In addition, a
number of peripheral demyelinating disorders are encountered, such as chronic inflammatory demyelinating
polyneuropathy, the Lewis-Sumner syndrome, and cryoglobulin-associated polyneuropathy with demyelinating features.
The spectrum of demyelinating forms also includes rare cases of iatrogenic central and peripheral nervous system
disorders, occurring during treatment with pegylated interferon. Herein, we review HCV-related demyelinating
conditions, and disclose the novel observation on the significantly increased frequency of chronic demyelinating
neuropathy with anti-myelin-associated glycoprotein antibodies in a cohort of 59 consecutive patients recruited at our
institution. We also report a second case of neuromyelitis optica with serum IgG autoantibody against the water channel
aquaporin-4. The prompt recognition of these atypical and underestimated complications of HCV infection is of crucial
importance in deciding which treatment option a patient should be offered.

Abstract
We report the case of a 62-year-old Caucasian woman who was admitted with urinary retention and lower limb paraesthesia following a week's prodromal illness of headache and malaise. Liver function tests showed a picture of acute hepatocellular dysfunction. She developed reduced lower limb power, brisk reflexes, extensor plantars, a sensory level at T8 and reduced anal sphincter tone, establishing a clinical diagnosis of transverse myelitis. A spinal MRI showed no evidence of cauda equina or spinal cord compression. Cerebrospinal fluid (CSF) analysis showed raised protein and raised white cell count. Hepatitis E IgM and IgG were positive and hepatitis E virus was found in her CSF. She was treated with methylprednisolone and is slowly recovering with physiotherapy.

Abstract
Cryoglobulinemia is characterized by a wide range of causes, symptoms, and outcomes. Hepatitis C virus (HCV) infection is detected in 30%-100% of patients with cryoglobulins. Although more than half the patients with cryoglobulinemic vasculitis present a relatively benign clinical course, some may present with potentially life-threatening situations. We conducted the current study to analyze the clinical characteristics and outcomes of HCV patients presenting with life-threatening cryoglobulinemic vasculitis. We evaluated 181 admissions from 89 HCV patients diagnosed with cryoglobulinemic vasculitis consecutively admitted to our department between 1995 and 2010. In addition, we performed a systematic analysis of cases reported to date through a MEDLINE search.The following organ involvements were considered to be potentially life-threatening in HCV patients with cryoglobulinemic vasculitis: cryoglobulinemic, biopsy-proven glomerulonephritis presenting with renal failure; gastrointestinal vasculitis; pulmonary hemorrhage; central nervous system (CNS) involvement; and myocardial involvement. A total of 279 patients (30 from our department and 249 from the literature search) fulfilled the inclusion criteria: 205 presented with renal failure, 45 with gastrointestinal vasculitis, 38 with CNS involvement, 18 with pulmonary hemorrhage, and 3 with myocardial involvement; 30 patients presented with more than 1 life-threatening cryoglobulinemic manifestation. There were 146 (52%) women and 133 (48%) men, with a mean age at diagnosis of cryoglobulinemia of 54 years (range, 25-87 yr) and a mean age at life-threatening involvement of 55 years (range, 25-87 yr). In 232 (83%) patients, life-threatening involvement was the first clinical manifestation of cryoglobulinemia. Severe involvement appeared a mean of 1.2 years (range, 1-11 yr) after the diagnosis of cryoglobulinemic vasculitis. Patients were followed for a mean of 14 months (range, 3-120 mo) after the diagnosis of life-threatening cryoglobulinemia. Sixty-three patients (22%) died. The main cause of death was sepsis (42%) in patients with glomerulonephritis, and cryoglobulinemic vasculitis itself in patients with gastrointestinal, pulmonary, and CNS involvement (60%, 57%, and 62%, respectively). In conclusion, HCV-related cryoglobulinemia may result in progressive (renal involvement) or acute (pulmonary hemorrhage, gastrointestinal ischemia, CNS involvement) life-threatening organ damage. The mortality rate of these manifestations ranges between 20% and 80%. Unfortunately, this may be the first cryoglobulinemic involvement in almost two-thirds of cases, highlighting the complex management and very elevated mortality of these cases.

Abstract
We report a case of acute myelitis associated with hepatitis C virus (HCV) infection. A Japanese woman developed left calf pain and weakness, but this quickly generalised to paraplegia. We diagnosed acute myelitis based on the results of clinical manifestations, an MRI examination and a cerebrospinal fluid (CSF) examination. The clinical condition and spinal cord lesions improved following intravenous administration of methylprednisolone. The patient had been diagnosed with HCV infection 11 years before the onset. We detected HCV RNA in the CSF, supporting the strong association of our patient's myelitis. However, it is difficult to conclude whether the neurological condition was caused directly by the viral load or indirectly by the immune response. We suggest that testing for HCV infection is important in patients with myelitis. In particular, anti-HCV antibody and HCV RNA should be measured in the patients' serum as well as CSF.

Abstract
Transverse myelitis (TM) includes a pathobiologically heterogeneous syndrome characterized by acute or subacute spinal cord dysfunction resulting in paresis, a sensory level, and autonomic (bladder, bowel, and sexual) impairment below the level of the lesion. Etiologies for TM can be broadly classified as parainfectious, paraneoplastic, drug/toxin-induced, systemic autoimmune disorders, and acquired demyelinating diseases. We discuss the clinical evaluation, workup, and acute and long-term management of patients with TM. Additionally, we briefly discuss various disease entities that may cause TM and their salient distinguishing features, as well as disorders that may mimic TM.

Abstract
Though well-known as a cause of liver disease, Hepatitis C virus infection is emerging as a cause of a variety of peripheral and central nervous system disorders. The virus causes chronic persistent infection with complex immune responses in the majority of individuals. Viral infection may have the potential to generate neurological illness through direct infection of neural cells or through immune-mediated mechanisms, including enhancement of autoimmune responses. Moreover, the mainstay of antiviral treatment of hepatitis C infection, interferon-alpha, is itself associated with neurological morbidity. Thus neurologists are increasingly faced with diagnosing or even predicting a wide spectrum of neurological complications of hepatitis C infection and/or its treatment.

Abstract
Chronic infection with hepatitis C virus (HCV) is associated with a wide spectrum of extrahepatic manifestations, affecting different organ systems. Neurological complications occur in a large number of patients and range from peripheral neuropathy to cognitive impairment. Pathogenetic mechanisms responsible for nervous system dysfunction are mainly related to the upregulation of the host immune response with production of autoantibodies, immune complexes, and cryoglobulins. Alternative mechanisms include possible extrahepatic replication of HCV in neural tissues and the effects of circulating inflammatory cytokines and chemokines.

Abstract
Neuromyelitis optica spectrum disorder (NMOSD) is characterized by optic neuritis or transverse myelitis with anti-aquaporin 4 (AQP4) antibodies (1). We herein present the case of a patient with NMOSD who also was affected with peripheral neuropathy. A 58-year-old woman developed gait disturbance and sensory impairment in the lower limbs. She exhibited longitudinally extensive transverse myelitis with anti-AQP4 antibodies. Nerve conduction studies showed demyelinating changes. Laboratory findings showed hepatitis-C virus (HCV) infection. Her peripheral neuropathy improved after immunotherapy. There have been no previous reports of NMO or NMOSD associated with neuropathy. The HCV infection or undetermined humoral factors other than the anti-AQP4 antibodies may have caused her peripheral neuropathy.

Abstract
Virus-induced spinal cord damage results from a cytolytic effect on anterior horn cells or from predominantly cellular immune-mediated damage of long white matter tracts. Infection with the hepatitis virus group, most notably hepatitis C virus, has infrequently been associated with the occurrence of myelitis. The pathogenesis of hepatitis virus-associated myelitis has not been clarified: virus-induced autoimmunity (humoral or cell-mediated, possibly vasculitic) seems the most likely disease mechanism. Limited available information offers no evidence of direct hepatitis virus infection of the spinal cord. Virus neuropenetration may occur after virus-infected mononuclear cells penetrate the blood-brain barrier, but a true neurolytic effect has not been demonstrated. Attacks of acute myelitis usually respond favorably to immunomodulatory therapy. Antiviral therapy plays no confirmed role in the treatment of acute bouts of myelitis, but may limit the relapsing course of HCV-associated myelitis.

Abstract
We describe the pathological features of a spinal cord biopsy from a 69-year-old woman with anti-aquaporin-4 antibody-negative recurrent longitudinal myelitis. Spinal cord MRI showed T2 high-intensity lesions with strong gadolinium enhancement, when episodes of sensory-motor impairment were repeated. The radiological abnormality was corrected by corticosteroid administration, but improvement of the symptoms was minimal. Although the patient had sicca symptoms and fulfilled four of the diagnostic criteria for Sjögren syndrome, the diagnosis was excluded, because of infection with hepatitis C virus, an exclusion criterion of Sjögren syndrome. In the spinal cord lesions, necrotic changes affected both myelin and axons. Infiltrating lymphocytes were predominantly T-cells. The proliferation of small vessels with hyalinization and concomitant occlusive change was remarkable. These pathological findings resembled those previously reported in Sjögren syndrome. Ultrastructurally, the endothelial cells of the small vessels showed features of activated cells and contained vesiculo-tubular structures in the cytoplasm, indicating that increased blood-brain barrier (BBB) permeability might contribute to pathogenesis. We speculated that increased BBB permeability and T-cell entry in the spinal parenchyma triggered pathological reactions resulting in necrotic changes in the spinal cord. Obstruction of small vessels might add ischemic damage to the lesions. The clinical course and pathological findings indicated that damage progressed rapidly in the spinal cord and was irreversible. The lesions apparently differed from typical demyelination plaques. Faced with such spinal cord lesions, a preventive therapeutic approach is necessary to avoid attack-associated disability.

Abstract
This report describes a patient who developed human T-cell leukemia virus type I-associated myelopathy (HAM) following a living-donor liver transplantation (LDLT) for liver cirrhosis due to hepatitis C virus (HCV) infection. Both the recipient and the living donor (his sister) were human T-cell leukemia virus type I (HTLV-I) carriers. Since the LDLT, he had been treated with immunosuppressive drugs such as tacrolimus and steroids as well as interferon-alpha to prevent rejection and a recurrence of the HCV infection, respectively. Even though the HTLV-I proviral load had decreased upon interferon treatment, he developed a slowly progressive gait disturbance with urinary disturbance 2 years after the LDLT and was diagnosed with HAM. This appears to be the first report of HAM development in an HLTV-I-infected LDLT recipient.
