Abstract
Vasculitis refers to heterogeneous clinicopathologic disorders that share the histopathology of inflammation of blood vessels. Unrecognized and therefore untreated, vasculitis of the nervous system leads to pervasive injury and disability making this a disorder of paramount importance to all clinicians. Headache may be an important clue to vasculitic involvement of central nervous system (CNS) vessels. CNS vasculitis may be primary, in which only intracranial vessels are involved in the inflammatory process, or secondary to another known disorder with overlapping systemic involvement. Primary neurologic vasculitides can be diagnosed with assurance after intensive evaluation that incudes tissue confirmation whenever possible.

Abstract
Cryoglobulinemia may result in small-to-medium vessel vasculitis. Central nervous system (CNS) involvement is rare, and presentation may range from stroke/transient ischemic attack, reversible ischemic neurological deficits, to encephalopathic syndromes. This is a rare case discussing cryoglobulinemia with CNS involvement. A 56-year-old female with a history of cryoglobulinemia was found unresponsive to verbal and physical stimuli. She was admitted to the intensive care unit. CT head without contrast showed diffuse cerebral edema and mass effect in the right cerebral hemisphere causing right to left midline shift, brainstem infarct, hemorrhage in the right lateral ventricle, and obstruction of the fourth ventricle. The patient was managed with hypertonic saline, external ventricular drain (EVD) placement, and high-dose steroids, which led to an improvement in her condition. In conclusion, testing for cryoglobulins and serologic tests for hepatitis C should be considered in syndromes of cerebral ischemia or infarction without an obvious cause, especially in young individuals since encephalopathy may be reversible. Cryoglobulinemia with CNS manifestations may be associated with purpura, high RF, and low C4. The treatment can be a combination of steroids, immunosuppressants, plasmapheresis, and rituximab. Cyclophosphamide may also be considered as adjunctive therapy to corticosteroids in rapidly progressive severe neurological complications. Further research for treatment standards in nonviral cryoglobulinemia is needed.

Abstract
PURPOSE OF REVIEW Vasculitis refers to heterogeneous clinicopathologic disorders that share the histopathology of inflammation of blood vessels. Unrecognized and therefore untreated, vasculitis of the nervous system or so called neurovasculitides, lead to pervasive injury and disability making these disorder of paramount importance to clinicians. RECENT FINDINGS Headache is an important clue to vasculitic involvement of central nervous system (CNS) vessels. CNS vasculitis may be primary, in which only intracranial vessels are involved in the inflammatory process, or secondary to another known disorder with overlapping systemic involvement. A suspicion of vasculitis based on the history, clinical examination, or laboratory studies warrants prompt evaluation and treatment to forestall progression and avert cerebral ischemia or infarction. There has been remarkable progress in the pathogenesis, diagnosis, and treatment of primary adult and pediatric CNS vasculitides predicated on achievements in primary systemic forms. SUMMARY Vasculitis can be diagnosed with certainty after intensive evaluation that includes tissue confirmation whenever possible. Clinicians must choose from among the available immune modulating, suppressive, and targeted immunotherapies to induce and maintain remission status and prevent relapse, tempered by the recognition of anticipated medication side effects.

Abstract
Mixed cryoglobulinemic vasculitis (CV) is occasionally caused by autoimmune diseases including systemic sclerosis. Multiorgan involvement such as skin, kidney, and peripheral nerve involvement is common in mixed CV. However, central nervous system (CNS) involvement is extremely rare. Here, we report a case of overlap syndrome of limited cutaneous systemic sclerosis and mixed cryoglobulinemic vasculitis with CNS involvement. The neurologic deficits and systemic symptoms improved promptly after steroid and cyclophosphamide therapy.

Abstract
BACKGROUND The prevalence and associations of mixed cryoglobulinemia (MC) in patients with spontaneous clearance of hepatitis C virus (HCV) remain elusive. MATERIALS AND METHODS A 13-year prospective cohort study of patients with spontaneous HCV clearance was conducted in a tertiary care centre. Baseline characteristics, incident cardiovascular and neurologic events and cancers were analysed. RESULTS Of 104 consecutive patients (mean age: 54.08 years old; females: 71 [68%]), 37 (34.6%) had MC and 6 (5.8%) had cirrhosis. MC (+) patients were more female (86% vs 58%, P = .002), had higher rate of cirrhosis (14% vs 1.5%, P = .012), higher levels of Immunoglobulin G (IgG; P = .001), IgM (P = .002) and fibrosis-4 (FIB-4) (P = .004), but lower levels of complement C4 (P = .034) than the MC (-) patients. Female gender (95% confidence interval [CI] of odds ratio: 1.402-26.715), levels of IgG (1.000-1.004), IgM (1.009-1.037) and FIB-4 (1.217-3.966) were independently associated with MC. Baseline rheumatoid factor (RF) levels were independently associated with incident cancer (95% CI hazard ratio [HR]: 1.001-1.030 [HR: 1.015], P = .039). With a cut-off value of 11.3 IU/mL, RF levels significantly predicted incident cancer (area under curve: 0.865, P = .002). No different cumulative incidences of cardiovascular and neurologic events, cancers or mortalities were identified between MC (+) and MC (-) patient. CONCLUSIONS Approximately 1/3 of patients with spontaneous HCV clearance yielded MC, which harboured similar characteristics of MC in patients with chronic hepatitis C. Despite the negligible role of MC in the prognosis of patients with spontaneous HCV clearance, the connection between RF and incident cancer demands further investigation.

Abstract
The vasculitides are diseases characterized by inflammation of blood vessels and inflammatory leukocytes in vessel walls. There is an increased propensity for ischemic stroke, resulting from compromise of vessel lumina with distal tissue ischemia; and hemorrhagic or nonhemorrhagic stroke, and aneurysmal formation and bleeding, due to loss of vessel integrity.

Abstract
Cryoglobulinemia is defined as the persistent presence in serum of abnormal immunoglobulins (Igs) that precipitate at low temperatures and dissolve again upon warming. Cryoglobulins may be composed only of a monoclonal Ig (simple type I cryoglobulinemia), of a monoclonal Ig bound to the constant domain of polyclonal Ig heavy chains (mixed type II cryoglobulinemia), or only of polyclonal Igs (mixed type III cryoglobulinemia). The manifestations of type I cryoglobulinemia are often related to intravascular obstruction, whereas those seen in the mixed cryoglobulinemias often originate in true immune complex-mediated vasculitis. The main clinical manifestations affect the skin (purpura, necrotic ulcers), joints, peripheral nervous system, and kidneys (membranoproliferative glomerulonephritis). Patients with type I cryoglobulinemia should be investigated for hematological malignancies (myeloma and B-cell lymphoma). Hepatitis C is the main diagnosis to consider in patients with mixed cryoglobulinemia, followed by connective tissue disease and B-cell non-Hodgkin's lymphoma. The treatment depends mainly on the cause of the cryoglobulinemia. For instance, hepatitis C virus (HCV) eradication is in order in patients with HCV-associated cryoglobulinemia vasculitis, and the underlying hematological malignancy must be treated in patients with type I cryoglobulinemia.

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
The liver has a central role in regulating inflammation by its capacity to secrete a number of proteins that control both local and systemic inflammatory responses. Chronic inflammation or an exaggerated inflammatory response can produce detrimental effects on target organs. Chronic hepatitis C virus (HCV) infection causes liver inflammation by complex and not yet well-understood molecular pathways, including direct viral effects and indirect mechanisms involving cytokine pathways, oxidative stress and steatosis induction. An increasing body of evidence recognizes the inflammatory response in chronic hepatitis C as pathogenically linked to the development of both liver-limited injury (fibrosis, cirrhosis and hepatocellular carcinoma) and extrahepatic HCV-related diseases (lymphoproliferative disease, atherosclerosis, cardiovascular and brain disease). Defining the complex mechanisms of HCV-induced inflammation could be crucial to determine the global impact of infection, to estimate progression of the disease, and to explore novel therapeutic approaches to avert HCV-related diseases. This review focuses on HCV-related clinical conditions as a result of chronic liver and systemic inflammatory states.

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
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
BACKGROUND Data on a link between HCV or HBV infection and the development of cardiovascular disease among HIV-negative and HIV-positive individuals are conflicting. We sought to investigate the association between HBV or HCV infection and myocardial infarction in HIV-infected individuals. METHODS The prospective observational database of the D:A:D collaboration of 11 cohorts of HIV-infected individuals, including 212 clinics in Europe, the United States and Australia was used. Multivariate Poisson regression was used to assess the effect of HCV or HBV infection on the development of myocardial infarction after adjustment for potential confounders, including cardiovascular risk factors, diabetes mellitus and exposure to antiretroviral therapy. RESULTS Of 33,347 individuals, 517 developed a myocardial infarction over 157,912 person-years, with an event rate of 3.3 events/1,000 person-years (95% confidence interval [CI] 3.0-3.6). Event rates (95% CIs) per 1,000 person-years in those who were HCV-seronegative and HCV-seropositive were 3.3 (3.0-3.7) and 2.7 (2.2-3.3), respectively, and for those who were HBV-seronegative, had inactive infection or had active infection were 3.2 (2.8-3.5), 4.2 (3.1-5.2) and 2.8 (1.8-3.9), respectively. After adjustment, there was no association between HCV seropositivity (rate ratio 0.86 [95% CI 0.62-1.19]), inactive HBV infection (rate ratio 1.07 [95% CI 0.79-1.43]) or active HBV infection (rate ratio 0.78 [95% CI 0.52-1.15]) and the development of myocardial infarction. CONCLUSIONS We found no association between HBV or HCV coinfection and the development of myocardial infarction among HIV-infected individuals.

Abstract
Cold agglutinin disease occurring with cryoglobulinemia is a rare occurrence. Here, we report a patient with mixed cryoglobulinemia that was treated with rituximab and, after response, developed an anti-Pr cold agglutinin that manifested with hemolysis and microvascular occlusion causing mesenteric ischemia and cerebral infarction. Unlike previous reports of patients with cryoglobulinemia and cold agglutinin disease, our patient did not have a detectable cryoprecipitate when his cold agglutinin manifested.

Abstract
Cryoglobulinemia are immune complexes that may induce systemic cryoglobulinemic vasculitis, a small-vessel vasculitis involving the skin, the joints, the peripheral nerve system, and the kidneys. During the last 15 years, progresses have been done after the discovery of the hepatitis C virus, the main cause of cryoglobulins. Main factors associated with cryoglobulin production are female gender, alcohol intake above 50 g/day, extensive liver fibrosis, and steatosis. Symptomatic cryoglobulins (i.e., vasculitis) are associated with older age, longer duration of infection, and main characteristics of cryoglobulin (type II, IgM kappa, high serum levels). The physiopathology is complex, and it involves humoral immunity, B- and T-cellular immunity but not the virus itself. Peg-Interféron alpha Ribavirine combination leads to a virological and clinical response of the vasculitis in about 70% of patients. In nonresponders, recent open series suggested the efficacy of Rituximab with a good response in up to 80% of patients but a relapse in 42% after 7 months after the last infusion. For future prospects and projects, new therapeutic strategies include a combination of best antiviral treatment with Peg-Interferon plus Ribavirin and Rituximab. Multicenter controlled trials are mandatory.

Abstract
Cryoglobulinemia refers to the presence in serum of immunoglobulins that precipitate at a cold temperature. Type I cryoglobulins are single monoclonal immunoglobulins usually associated with haematological disorders. Types II and III are mixed cryoglobulins, composed of monoclonal or polyclonal IgM respectively, having rheumatoid factor activity that bind to polyclonal immunoglobulins. Mixed cryoglobulinemia (MC) syndrome is a consequence of immune-complex mediated vasculitis and is characterized by a typical clinical triad: purpura, weakness, arthralgias; many organs particularly kidney and peripheral nervous system may be involved. MC may be associated with infectious and systemic disorders and since 1990 studies have demonstrated that hepatitis C virus (HCV) may be considered the principal trigger of the disease. The relation between MC and HCV infection shows new insights in the interpretation of the link between viral infection, autoimmune phenomena and lymphoproliferative disorders evolution. In fact, the virus chronically stimulates B-cell polyclonal proliferation from which a monoclonal population may emerge. In symptomatic patients with HCV related MC therapeutic strategy should include an attempt at viral eradication. Antiviral therapy may also be effective in determining the regression of B-cell lymphoproliferative disorder. Rituximab could represent a safe and effective alternative to standard immunosuppression and exerts selective B-cell control.

Abstract
Central nervous system involvement in hepatitis C virus (HCV)-related cryoglobulinemia is uncommon. We report a patient with HCV-related type II mixed cryoglobulinemia who suffered a transient ischemic attack (TIA) associated with deep venous thrombosis and pulmonary embolism. The mechanism of TIA was diagnosed as paradoxical embolism, and we suspect that the cause of the TIA was associated with HCV-related type II mixed cryoglobulinemia.

Abstract
Chronic liver disease caused by hepatitis C virus (HCV) infection is commonly associated with extrahepatic manifestations, mainly mixed cryoglobulinaemia. Neurological complications in HCV-infected patients occur predominantly in the peripheral nervous system. Peripheral neuropathy in HCV infection is primarily associated with mixed cryoglobulinaemia. Central nervous system (CNS) involvement is more rarely reported. In this review, peripheral and CNS involvement associated with chronic HCV infection are described. The underlying mechanisms and treatment possibilities are discussed.

Abstract
UNLABELLED VIRUSES, THE CAUSE OF VASCULITIS: Although the majority of systemic vasculitis are of unknown causes, the responsibility of a viral infection has been formally demonstrated in some of them and specific treatment can permanently cure them. Each virus incriminated accounts for a particular type of vasculitis. HEPATITIS B VIRAL INFECTION (HBV): Is the cause of polyarteritis nodosa in 36 to 50% of cases. The onset of the symptomatology is acute, usually within a few months following the infection; it is comparable to that observed in the absence of HBV infection. CRYOGLOBULINEMIA RELATED TO THE HEPATITIS C VIRUS (HCV): The clinical manifestations are those of systemic vasculitis with particular tropism for the skin (involvement generally inaugural and almost constant), peripheral nerves and the glomerula. They occur fairly late during the infection. VASCULITIS ASSOCIATED WITH HIV INFECTION: There is strong tropism for the peripheral (multi-neuritis) and central nervous system. During acute parvovirus B19 infection Vasculitis lesions have occasionally been reported following the viremic phase, generally limited to one or several flares of vascular purpura predominating on the lower limbs. FOLLOWING VARICELLA-HERPES ZOSTER INFECTION: Vasculitis occasionally develops in the form of a central neurological deficiency (locomotor deficiency with or without aphasia around one month after an ophthalmologic herpes zoster) or involving the retina or, more rarely, the skin or the kidneys. VASCULITIS ASSOCIATED WITH CYTOMEGALOVIRAL INFECTION: Predominantly observed in immunodepressed patients, vasculitis after CMV infection is diffuse and basically involving the digestive tube, notably the colon, the central nervous system and the skin. A RARE COMPLICATION OF AN HTLV1 INFECTION: Vasculitis of the retina often in the form of necrotic retinitis is often associated with spasmodic paraparessia. THERAPEUTIC STRATEGY For many vasculitis of viral origin, corticosteroid and immunosuppressive treatments are only indicated in second intention following failure with antiviral agents and the combination of antivirals and plasma exchanges.

Abstract
Hepatitis C is an RNA virus responsible for chronic infection in at least 4 million Americans. Patients are often unaware that they have contracted the virus until the appearance of long-term consequences of the infection, primarily cirrhosis and hepatocellular carcinoma. Many patients with hepatitis C have comorbid psychiatric and/or substance abuse disorders. Treatments for hepatitis C infection are based on interferon-alfa therapy and have shown increasing effectiveness in recent years; however, interferon-alfa therapy also poses significant risks for physical and neuropsychiatric side effects. Since psychiatrists often serve as primary caregivers for patients who are at higher risk for hepatitis C infection, knowledge about the diagnosis, prognosis, and treatment of this disease is needed. In the first half of this article, the authors review the epidemiology, transmission, pathophysiology and disease course of hepatitis C, as well as the neuropsychiatric complications of hepatitis C infection. They also discuss the incidence of comorbid psychiatric disorders in patients with hepatitis C infection and consider the impact of the infection on patients' quality of life. The authors then provide an overview of the clinical management of HCV infection, including screening procedures, decision-making about treatment, available treatments (interferon-alfa, pegylated interferon-alpha, combination therapy with interferon and ribavirin) and their side effects and potential drug-drug interactions, and prediction of treatment response. The authors then discuss management of the neuropsychiatric complications of treatment with interferon-alpha and ribavirin, including depression, mania and psychosis, and cognitive and neurological complications. The final section of the article focuses on special issues related to the treatment of hepatitis C infection in patients with substance abuse or dependence and/or other comorbid psychiatric illness.

Abstract
A link between certain infectious microorganisms and an increased risk of atherosclerotic disease has been suggested. By analyzing the data of subjects who had undergone general health-screening tests, a possible association between carotid atherosclerosis and seropositivity of antibody against hepatitis C virus (HCV) has been previously reported. In the present study, a possible link between carotid atherosclerosis and HCV core protein positivity was assessed, because it is postulated to be a better marker of viremia and thus persistent infection. Of the 1992 enrolled subjects, 496 (25%) had carotid artery plaque, and 25 (1.3%) were positive for HCV core protein. Carotid artery plaque was positive in 480/1967 (24%) and 16/25 (64%) of the core protein-negative and core protein-positive subjects, respectively (p<0.0001 by chi(2) test). Serum concentrations of transaminases were higher in core protein-positive subjects, but albumin concentrations were not significantly different between the 2 groups. Multivariate logistic regression analysis showed that HCV core protein positivity is an independent predictor of carotid plaque with an odds ratio of 5.61 (95% confidence interval 2.06-15.26, p<0.001). These data further support the possible link between persistent HCV infection and carotid atherosclerosis in the subjects without severe liver dysfunction.
