Abstract
INTRODUCTION Coronavirus disease (COVID-19) vaccines have been reported to have ocular side effects including scleritis and episcleritis. PURPOSE To report scleritis and episcleritis within a month following administration of COVID-19 vaccine. METHODS Retrospective case series. RESULTS 15 eyes of 12 consecutive patients with scleritis and episcleritis from March 2021 to September 2021 were included. The mean time of onset of symptoms in patients with scleritis was 15.7 days (range, 4-30) and for episcleritis it was 13.2 days (range 2-30). Patients received COVISHIELD™ (10 patients) and COVAXIN™ (2 patients). Five patients had denovo inflammation and seven had recurrent inflammation. Episcleritis patients were treated with topical steroids and systemic COX2 inhibitors while patients with scleritis were treated with topical steroids/oral steroids/antiviral medications depending on the aetiology. CONCLUSION Scleritis and episcleritis following COVID-19 vaccination are milder and do not require intensive immunosuppression except in rare cases.

Abstract
The COVID-19 pandemic has galvanized the global response towards the development of new vaccines based on novel technologies at an unprecedented pace. Since the widespread implementation of vaccination campaigns, case reports on vaccines' systemic side effects, including ocular manifestations, have emerged. Since administered vaccines are generally not able to cause the disease in the recipient, or induce an immune response against the pathogen, we hypothesize that the development of ocular phenomena post-COVID-19 vaccination may occur via an immune response elicited by the vaccine. Of many, the most common ocular adverse events include facial nerve palsy, central venous sinus thrombosis and acute anterior uveitis. These COVID-19 vaccine-induced ocular (CVIO) adverse events could resemble the ocular findings in some of the COVID-19 patients. This review will provide a comprehensive overview of published ocular side effects potentially associated with COVID-19 vaccination and serve as a springboard for further research into CVIO adverse events.

Abstract
Cryoglobulins consist of serum immunoglobulins that precipitate below 37°C and resolubilize upon warming. The clinical triad of cryoglobulinemia usually includes purpura, weakness, and arthralgia. Cryoglobulinemic syndrome, clinically defined as a systemic vasculitis, is associated with chronic infection with hepatitis C virus (HCV) and autoimmune disorders and can evolve into B-cell malignancies. While the current literature about HCV-associated cryoglobulinemia is not very limited, little is known about the immunologic and serologic profiles of affected patients. Therefore, comprehension of the pathogenetic mechanisms underlying cryoprecipitation could be very helpful. Due to the persistence of viral antigenic stimulation, biomarkers to use after the worsening progression of HCV infection to lymphoproliferative and/or autoimmune diseases are widely needed. Laboratory methods used to detect and characterize low concentrations of cryoprecipitates and immunotyping patterns could improve patient management. The most critical factor affecting cryoglobulin testing is that the pre-analytical phase is not fully completed at 37°C.

Abstract
Clinical spectrum of hepatitis C virus (HCV)-related cryoglobulinemia varies from an asymptomatic presentation to severe vasculitis and lymphoma. A recent study in HCV-negative patients suggests that low cryoglobulins (CGs) levels are responsible for severe renal and neurological complications. The aim of this study was to identify a panel of serological biomarkers associated with low levels of CGs in HCV-positive patients. We studied a population of 79 untreated patients with chronic HCV infection: 13 naïve patients without CGs; 28 patients with asymptomatic mixed cryoglobulinemia (MC) and low levels of CGs (16/28 with polyclonal type III and 12/28 with microheterogeneous type III CGs); 38 patients with symptomatic MC and high levels of type II CGs. Serum samples were collected and examined for rheumatoid factor (RF) IgG and IgM, free light chains (FLCs) and C3 and C4 complement components. We found that RF-IgG and IgM, free k chains and k+λ were increased while C4 component was reduced, both in symptomatic and asymptomatic patients. Our results suggest that, even in absence of MC symptoms, the low levels of CGs may represent a trigger of activation for immune system in course of HCV infection. The identification of a correlated biomarkers panel could improve the clinical management of these patients and pave the way for target treatment strategies. © 2018 BioFactors, 45(3):318-325, 2019.

Abstract
We assessed the change of homocysteine (Hcy), insulin-like growth factor one (IGF-Ι) and oestrogen (E2) levels in patients with erectile dysfunction (ED) associated with chronic hepatitis C virus (HCV) infection. Eighty-five male patients with chronic HCV and/or ED were enrolled in this study. Seventy-five men were assigned to three equal groups (n = 25/each); Group A: patients who had chronic HCV and ED. Group B: patients who had chronic HCV and had no ED complaint. Group C: patients who had ED with no chronic HCV. In addition to 10 control patients with no ED or chronic HCV (Group D). All patients were subjected to: detailed medical and sexual history, complete physical examination, laboratory assessment including measurement of serum Hcy, IGF-1 and E2. The means of international index of erectile function scores were 8 and 16 in groups A and C respectively. There were significant differences in Hcy, IGF-I and E2 among study groups (p < 0.05 for each). There were significant differences in Hcy between patients with Child B and Child C. A strong association between severity of ED and chronic HCV was demonstrated. There was statistically significant increase of Hcy and E2 levels and reduction in IGF-I level in patients with ED associated with chronic HCV infection.

Abstract
Cryoglobulins are immunoglobulins that precipitate in serum at temperatures below 37°C and resolubilize upon warming. The clinical syndrome of cryoglobulinemia usually includes purpura, weakness, and arthralgia, but the underlying disease may also contribute other symptoms. Blood samples for cryoglobulin are collected, transported, clotted and spun at 37°C, before the precipitate is allowed to form when serum is stored at 4°C in a Wintrobe tube for at least seven days. The most critical and confounding factor affecting the cryoglobulin test is when the preanalytical phase is not fully completed at 37°C. The easiest way to quantify cryoglobulins is the cryocrit estimate. However, this approach has low accuracy and sensitivity. Furthermore, the precipitate should be resolubilized by warming to confirm that it is truly formed of cryoglobulins. The characterization of cryoglobulins requires the precipitate is several times washed, before performing immunofixation, a technique by which cryoglobulins can be classified depending on the characteristics of the detected immunoglobulins. These features imply a pathogenic role of these molecules which are consequently associated with a wide range of symptoms and manifestations. According to the Brouet classification, Cryoglobulins are grouped into three types by the immunochemical properties of immunoglobulins in the cryoprecipitate. The aim of this paper is to review the major aspects of cryoglobulinemia and the laboratory techniques used to detect and characterize cryoglobulins, taking into consideration the presence and consequences of cryoglobulinemia in Hepatitis C Virus (HCV) infection.

Abstract
Due to immune abnormalities and the use of steroids and immunosuppressant treatment, patients with rheumatic diseases are susceptible to infections. Vaccination is one of the most important prevention tools in modern medicine. A discussion on risk-benefit or cost-benefit analysis, and advisory on individual vaccines or vaccination programs falls outside the scope of this review. In particularly, this review summarizes the knowledge about the effectiveness and safety vaccinations in patients with autoimmune inflammatory rheumatic diseases (AIIRD) treated with biologics. Finally, we aim to provide vaccination plans basis for clinical management of rheumatic patients depending upon prevaccination antibody titers, drug treatments and immunological potential.

Abstract
Immunoglobulin variable region heavy chain (IgVH ) somatic gene diversification is instrumental in the transformation process that characterizes hepatitis C virus (HCV)-related B cell lymphoproliferative disorders. However, the extent to which activation-induced cytidine deaminase (AID), an enzyme essential for IgV gene somatic hypermutation (SHM), is active in cryoglobulinaemic vasculitis (CV) remains unclear. AID mRNA expression in the peripheral blood of 102 chronically hepatitis C virus (HCV)-infected patients (58 with and 44 without CV) and 26 healthy subjects was investigated using real-time reverse transcription-polymerase chain reaction (RT-PCR). The features of activation-induced cytidine deaminase (AID) protein and mRNA transcripts were explored in liver tissue biopsies and portal tracts isolated using laser capture microdissection. In chronically HCV-infected patients, AID mRNA expression was almost threefold higher in those with than in those without CV and sevenfold higher than in healthy subjects (median-fold: 6.68 versus 2.54, P = 0.03 and versus 0.95, P = 0.0003). AID transcript levels were significantly higher in polyclonal than in clonally restricted B cell preparations in either CV or non-CV patients (median-fold, 15.0 versus 2.70, P = 0.009 and 3.46 versus 1.58, P = 0.02, respectively). AID gene expression was found to be related negatively to age and virological parameters. AID protein was found in portal tracts containing inflammatory cells that, in several instances, expressed AID mRNA transcripts. Our data indicate that the aberrant expression of AID may reflect continuous B cell activation and sustained survival signals in HCV-related CV patients.

Abstract
BACKGROUND Type 1 narcolepsy is a neurological disorder characterized by excessive daytime sleepiness and cataplexy associated with the HLA allele DQB1*06:02. Genetic predisposition along with external triggering factors may drive autoimmune responses, ultimately leading to the selective loss of hypocretin-positive neurons. OBJECTIVE The aim of this study was to investigate potential aetiological factors in Swedish cases of postvaccination (Pandemrix) narcolepsy defined by interferon-gamma (IFNγ) production from immune cells in response to molecularly defined targets. METHODS Cellular reactivity defined by IFNγ production was examined in blood from 38 (HLA-DQB1*06:02(+) ) Pandemrix-vaccinated narcolepsy cases and 76 (23 HLA-DQB1*06:02(+) and 53 HLA-DQB1*06:02(-) ) control subjects, matched for age, sex and exposure, using a variety of different antigens: β-haemolytic group A streptococcal (GAS) antigens (M5, M6 and streptodornase B), influenza (the pandemic A/H1N1/California/7/09 NYMC X-179A and A/H1N1/California/7/09 NYMC X-181 vaccine antigens, previous Flu-A and -B vaccine targets, A/H1N1/Brisbane/59/2007, A/H1N1/Solomon Islands/3/2006, A/H3N2/Uruguay/716/2007, A/H3N2/Wisconsin/67/2005, A/H5N1/Vietnam/1203/2004 and B/Malaysia/2506/2004), noninfluenza viral targets (CMVpp65, EBNA-1 and EBNA-3) and auto-antigens (hypocretin peptide, Tribbles homolog 2 peptide cocktail and extract from rat hypothalamus tissue). RESULTS IFN-γ production was significantly increased in whole blood from narcolepsy cases in response to streptococcus serotype M6 (P = 0.0065) and streptodornase B protein (P = 0.0050). T-cell recognition of M6 and streptodornase B was confirmed at the single-cell level by intracellular cytokine (IL-2, IFNγ, tumour necrosis factor-alpha and IL-17) production after stimulation with synthetic M6 or streptodornase B peptides. Significantly, higher (P = 0.02) titres of serum antistreptolysin O were observed in narcolepsy cases, compared to vaccinated controls. CONCLUSION β-haemolytic GAS may be involved in triggering autoimmune responses in patients who developed narcolepsy symptoms after vaccination with Pandemrix in Sweden, characterized by a Streptococcus pyogenes M-type-specific IFN-γ cellular immune response.

Abstract
There are several extrahepatic cutaneous manifestations associated with hepatitis B and hepatitis C virus infection. Serum sickness and polyarteritis nodosa are predominantly associated with hepatitis B infection, whereas mixed cryoglobulinemia associated vasculitis and porphyria cutanea tarda are more frequently seen in hepatitis C infection. The clinico-pathogenic associations of these skin conditions are not completely defined but appear to involve activation of the host immune system including the complement system. Management of the aforementioned cutaneous manifestations of viral hepatitis is often similar to that done in cases without viral hepatitis, with control of immune activation being a key strategy. In cases associated with hepatitis B and C, control of viral replication with specific antiviral therapy is also important and associated with improvement in most of the associated clinical manifestations.

Abstract
BACKGROUND Various kinds of autoimmune diseases have been reported to have a significant relationship with persistent hepatitis c virus (HCV) infection and Th17 cells. Previously, our group reported that the existence of HCV in T lymphocytes could affect the development of CD4+ helper T cells and their proliferation, in addition to the induction of immunoglobulin hyper-mutation. METHODS Therefore, we analyzed the relationship between persistent infection of HCV and the mechanism of Th17 cell induction ex vivo and in vitro. RESULTS The prevalence of autoimmune-related diseases in chronic hepatitis c patients (CH-C) was significantly higher than in other types of chronic hepatitis (hepatitis B and NASH). A significantly higher frequency of IL6 and TGF-β double-high patients was detected in CH-C than in other liver diseases. Moreover, these double-high patients had significantly higher positivity of anti-nuclear antibody, cryoglobulinemia, and lymphotropic HCV and higher amounts of IL1-β, IL21, IL23. In addition to the previously reported lymphotropic SB-HCV strain, we found a novel, genotype 1b lymphotropic HCV (Ly-HCV), by deep sequencing analysis. Lymphotropic-HCV replication could be detected in the lymphoid cells with various kinds of cytokine-conditions including IL1β, IL23, IL6 and TGF-β in vitro. Infection by HCV could significantly enhance the development of Th17 cells. The HCV protein responsible for inducing the Th17 cells was HCV-Core protein, which could enhance the STAT-3 signaling and up-regulate the expression of RORγt as a Th17 master gene. CONCLUSION Infection by lymphotropic HCV might enhance the Th17 development and contribute to understanding the pathogenesis of autoimmune-related diseases.

Abstract
Nucleotide biosynthesis is a highly regulated process necessary for cell growth and replication. Cytoplasmic structures in mammalian cells, provisionally described as rods and rings (RR), were identified by human autoantibodies and recently shown to include two key enzymes of the CTP/GTP biosynthetic pathways, cytidine triphosphate synthetase (CTPS) and inosine monophosphate dehydrogenase (IMPDH). Several studies have described CTPS filaments in mammalian cells, Drosophila, yeast, and bacteria. Other studies have identified IMPDH filaments in mammalian cells. Similarities among these studies point to a common evolutionarily conserved cytoplasmic structure composed of a subset of nucleotide biosynthetic enzymes. These structures appear to be a conserved metabolic response to decreased intracellular GTP and/or CTP pools. Antibodies to RR were found to develop in some hepatitis C patients treated with interferon-α and ribavirin. Additionally, the presence of anti-RR antibodies was correlated with poor treatment outcome.

Abstract
(C-X-C motif) ligand (CXCL)10 (CXCL10) belongs to the ELR(-) CXC subfamily chemokine. CXCL10 exerts its function through binding to chemokine (C-X-C motif) receptor 3 (CXCR3), a seven trans-membrane receptor coupled to G proteins. CXCL10 and its receptor, CXCR3, appear to contribute to the pathogenesis of many autoimmune diseases, organ specific (such as type 1 diabetes, autoimmune thyroiditis, Graves' disease and ophthalmopathy), or systemic (such as rheumatoid arthritis, psoriatic arthritis, systemic lupus erythematosus, mixed cryoglobulinemia, Sjögren syndrome, or systemic sclerosis). The secretion of CXCL10 by cluster of differentiation (CD)4+, CD8+, natural killer (NK) and NK-T cells is dependent on interferon (IFN)-γ, which is itself mediated by the interleukin-12 cytokine family. Under the influence of IFN-γ, CXCL10 is secreted by several cell types including endothelial cells, fibroblasts, keratinocytes, thyrocytes, preadipocytes, etc. Determination of high level of CXCL10 in peripheral fluids is therefore a marker of host immune response, especially T helper (Th)1 orientated T-cells. In tissues, recruited Th1 lymphocytes may be responsible for enhanced IFN-γ and tumor necrosis factor-α production, which in turn stimulates CXCL10 secretion from a variety of cells, therefore creating an amplification feedback loop, and perpetuating the autoimmune process. Further studies are needed to investigate interactions between chemokines and cytokines in the pathogenesis of autoimmune diseases and to evaluate whether CXCL10 is a novel therapeutic target in various autoimmune diseases.

Abstract
Cirrhosis and hepatocellular carcinoma are the prototypic complications of chronic hepatitis C virus infection in the liver. However, hepatitis C virus also affects a variety of other organs that may lead to significant morbidity and mortality. Extrahepatic manifestations of hepatitis C infection include a multitude of disease processes affecting the small vessels, skin, kidneys, salivary gland, eyes, thyroid, and immunologic system. The majority of these conditions are thought to be immune mediated. The most documented of these entities is mixed cryoglobulinemia. Morphologically, immune complex depositions can be identified in small vessels and glomerular capillary walls, leading to leukoclastic vasculitis in the skin and membranoproliferative glomerulonephritis in the kidney. Other HCV-associated entities include porphyria cutanea tarda, lichen planus, necrolytic acral erythema, membranous glomerulonephritis, diabetic nephropathy, B-cell non-Hodgkin lymphomas, insulin resistance, sialadenitis, sicca syndrome, and autoimmune thyroiditis. This paper highlights the histomorphologic features of these processes, which are typically characterized by chronic inflammation, immune complex deposition, and immunoproliferative disease in the affected organ.

Abstract
Cytokines are intercellular mediators involved in viral control and liver damage being induced by infection with hepatitis C virus (HCV). The complex cytokine network operating during initial infection allows a coordinated, effective development of both innate and adaptive immune responses. However, HCV interferes with cytokines at various levels and escapes immune response by inducing a T-helper (Th)2/T cytotoxic 2 cytokine profile. Inability to control infection leads to the recruitment of inflammatory infiltrates into the liver parenchyma by interferon (IFN)-gamma-inducible CXC chemokine ligand (CXCL)-9, -10, and -11 chemokines, which results in sustained liver damage and eventually in liver cirrhosis. The most important systemic HCV-related extrahepatic diseases--mixed cryoglobulinemia, lymphoproliferative disorders, thyroid autoimmune disorders, and type 2 diabetes--are associated with a complex dysregulation of the cytokine/chemokine network, involving proinflammatory and Th1 chemokines. The therapeutical administration of cytokines such as IFN-alpha may result in viral clearance during persistent infection and reverts this process.

Abstract
Hepatitis C virus (HCV) is a significant health problem facing the world. This virus infects more than 170 million people worldwide and is considered the major cause of both acute and chronic hepatitis. Persons become infected mainly through parenteral exposure to infected material by blood transfusions or injections with nonsterile needles. Although the sexual behavior is considered as a high risk factor for HCV infection, the transmission of HCV infection through sexual means, is less frequently. Currently, the available treatment for patients with chronic HCV infection is interferon based therapies alone or in combination with ribavirin and protease inhibitors. Although a sustained virological response of patients to the applied therapy, a great portion of patients did not show any response. HCV infection is mostly associated with progressive liver diseases including fibrosis, cirrhosis and hepatocellular carcinoma. Although the focus of many patients and clinicians is sometimes limited to that problem, the natural history of HCV infection (HCV) is also associated with the development of several extrahepatic manifestations including dermatologic, rheumatologic, neurologic, and nephrologic complications, diabetes, arterial hypertension, autoantibodies and cryglobulins. Despite the notion that HCV-mediated extrahepatic manifestations are credible, the mechanism of their modulation is not fully described in detail. Therefore, the understanding of the molecular mechanisms of HCV-induced alteration of intracellular signal transduction pathways, during the course of HCV infection, may offer novel therapeutic targets for HCV-associated both hepatic and extrahepatic manifestations. This review will elaborate the etiopathogenesis of HCV-host interactions and summarize the current knowledge of HCV-associated diseases and their possible therapeutic strategies.

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
The pathways leading to autoimmunity remain enigmatic despite numerous lines of experimental inquiry and epidemiological evidence. The mechanisms leading to the initiation and perpetuation of specific diseases such as primary biliary cirrhosis (PBC) or multiple sclerosis (MS) remain largely enigmatic, although it is established that a combination of genetic predisposition and environmental stimulation is required. The growing number of genome-wide association studies and the largely incomplete concordance for autoimmune diseases in monozygotic twins concur to support the role of the environment (including infectious agents and chemicals) in the breakdown of tolerance leading to autoimmunity through different mechanisms. In the present article we illustrate the current hypotheses related to an environmental impact on the onset of PBC and MS as two representative conditions investigated with complementary approaches. Indeed, while a role of post-translational antigen modifications has been proposed for MS, this field remain unexplored in PBC where, conversely, most evidence is gathered from geoepidemiology and experimental data on xenobiotics or infectious agents.

Abstract
Infectious agents have been implicated in the etiopathogenesis of various vasculitides via numerous and overlapping mechanisms including direct microbial invasion of endothelial cells, immune complex mediated vessel wall damage and stimulation of autoreactive B and/or T cells through molecular mimicry and superantigens. While the causative role of hepatitis B virus in polyarteritis nodosa and hepatitis C virus in mixed cryoglobulinemia is clearly established, evidence for the association of other infectious agents with vasculitis, including human immunodeficiency virus, parvovirus B19, cytomegalovirus, varicella zoster virus, Staphylococcus aureus, rickettsiaceae, Treponema pallidum and Borrelia burgdorferi, among numerous others, is accumulating. The spectrum of association of infectious agents; bacteria, viruses and parasites, with systemic vasculitides, will be reviewed herewith.

Abstract
To evaluate CXCL10 and CCL2 in patients with hepatitis C virus chronic infection in presence/absence of autoimmune thyroiditis (AT). CXCL10 was significantly higher in: (1) patients with AT than controls without AT (control 1) (P < 0.001; ANOVA); (2) patients with hepatitis C infection than control 1 and patients with AT (P < 0.001); (3) patients with hepatitis C virus chronic infection and AT (HCV+AT) than control 1 and patients with AT (P < 0.001) and hepatitis C (P = 0.004). By defining a high CXCL10 level as a value >218 pg/mL, 2% of control 1, 14% of patients with AT, 68% of patients with hepatitis C infection, 81% of HCV+AT had high CXCL10 (P < 0.0001; chi-square). CCL2 was similar in control 1 and patients with AT. CCL2 was significantly higher in: (1) patients with hepatitis C infection than control 1 (P = 0.04; ANOVA); (2) HCV+AT than patients with AT (P = 0.03) and control 1 (P = 0.02); no difference was observed between HCV with or without AT. Our study demonstrates: (1) higher circulating CXCL10 and CCL2 in patients with hepatitis C virus chronic infection than in controls; (2) higher CXCL10 in HCV+AT than in patients with hepatitis C infection, suggesting a stronger Th1 immune response in these patients.

Abstract
In genetically predisposed individuals, viruses, bacteria, or parasitic infectious agents are suspected to induce autoimmunity and/or to exacerbate the disease once the self-tolerance is broken. Although direct evidence for this association is still lacking, numerous data from animal models as well as from humans support the hypothesis of a direct contribution of pathogens to the induction of several autoimmune diseases. This review focused on the possible role of infectious agents as triggers of autoimmunity in polymyositis (PM) and dermatomyositis (DM). Epidemiological studies, clinical and experimental findings that support the hypothesis of infection-induced PM and DM are summarized and discussed. In addition, immune response abnormalities and immunosuppressive medications may be responsible for the high percentage of infectious complications in PM and DM patients. In this review, the increased risk of developing infections in these patients is also underlined and published data are reported.

Abstract
PURPOSE OF REVIEW To review the current literature and summarize the main principles found between viral infections and the subsequent production of autoantibodies. RECENT FINDINGS We concentrate on recent findings involving three viral agents, one of which is Epstein-Barr virus, which has been associated with many autoimmune diseases and is classically considered to induce systemic lupus erythematosus. As we will discuss, this occurs through molecular mimicry between Epstein-Barr virus nuclear antigen 1 and lupus-specific antigens such as Ro, La or dsDNA, through induction of Toll-like receptor hypersensitivity by Epstein-Barr virus latent membrane protein 2A or by creating immortal B and T cells by loss of apoptosis. Hepatitis B virus was found to share amino acid sequences with different autoantigens. Tissue damage and the release of intracellular components is just another example of the autoantibody production caused by this virus. Cytomegalovirus has often been controversially associated with several autoimmune diseases and, although is the least understood viral infection of the three, appears to be somewhat suspicious. SUMMARY Understanding the infectious origin of autoimmune diseases is important as we aim to identify high-risk patients and disrupt this process with vaccines or other medications, ultimately delaying or even preventing the evolution of autoimmune diseases.

Abstract
Hepatitis C virus (HCV) infection is a global health problem, being the second most common chronic viral infection in the world with a global prevalence of about 3% (about 180 million people). HCV is both an hepatotropic and a lymphotropic virus; and chronic infection could cause, on one hand, chronic hepatitis, cirrhosis and hepatocellular carcinoma and on the other hand several extrahepatic diseases including, first, mixed cryoglobulinemia and lymphoma. The association between hepatic (hepatocellular carcinoma) and extrahepatic (lymphoma, thyroid cancer) malignancies has justified the inclusion of HCV among human cancer viruses. The pathogenesis of HCV-related sequelae (hepatic or extrahepatic) is not fully understood representing a challenge of prime importance in light of the optimization of clinico-therapeutic management of these patients. Combined treatment with pegylated interferon plus ribavirin is presently the first-line, gold standard treatment of most HCV-related diseases. However, mainly in the case of extrahepatic manifestations, a cautious approach to the patient, with a case to case accurate tailoring of therapy is frequently requested. The present review will outline the principal aspects of such HCV-induced systemic disease focusing on extrahepatic manifestations.

Abstract
The presence of antibodies to cyclic citrullinated peptide (CCP) has high specificity in the diagnosis of rheumatoid arthritis (RA). Hepatitis C virus (HCV) infection may induce extra-hepatic manifestations, such as polyarthritis that mimic RA. The aim of this study was to determine the prevalence of anti-CCP antibodies in HCV-infected patients with or without arthritis, rheumatoid factor (RF), or cryoglobulinemia and to investigate whether anti-CCP antibodies may be helpful in discriminating patients with RA from patients with HCV-associated arthropathy. A total of 44 patients with RA, 34 patients with HCV infections, and 42 control patients with non-RA rheumatic diseases were recruited for the study. Anti-CCP antibody levels were determined by enzyme-linked immunosorbent assay. We found that, consistent with other reports, patients with RA were more likely to have high titers of anti-CCP antibody than HCV-infected or control patients. A significant number of HCV-infected patients with neither RF nor cryoglobulinemia were also positive for anti-CCP antibodies (the three positive values were 36.10, 8.65, and 5.83 U/ml, P < 0.01 compared with the control patients). The presence of cryoglobulinemia and/or RF in HCV-infected patients did not affect the anti-CCP outcomes. Although anti-CCP antibodies remain to be a very useful tool in discriminating RA from non-RA, HCV-infected patients with neither RF nor cryoglobulinemia may have anti-CCP antibodies. Because of limited patient numbers, this tentative conclusion may need further confirmation with inclusion of more patient population.

Abstract
To date, it is believed that the origin of autoimmune diseases is one of a multifactorial background. A genetic predisposition, an immune system malfunction or even backfire, hormonal regulation, and environmental factors all play important roles in the pathogenesis of autoimmune diseases. Among these environmental factors, the role of infection is known to be a major one. Epstein-Barr virus (EBV) and cytomegalovirus (CMV) are considered to be notorious as they are consistently associated with multiple autoimmune diseases. A cohort of 1595 serum samples, of 23 different autoimmune disease groups, was screened for evidence of prior infection with EBV and CMV. All samples were screened for antibodies against EBV nuclear antigen-1 (IgG), EBV viral capsid antigen (IgG and IgM), EBV early antigen (IgG), EBV heterophile antibody, and CMV (IgG and IgM) antibodies using Bio-Rad's BioPlex 2200. A new association is proposed between EBV and polymyositis, as results show a significant increase in titers of various EBV target analytes when compared with healthy controls. Our results also support prior information suggesting the association between EBV and multiple autoimmune diseases, including SLE, antiphospholipid syndrome, rheumatoid arthritis, multiple sclerosis, pemphigus vulgaris, giant cell arthritis, Wegener's granulomatosis, and polyarteritis nodosa (PAN). Elevated CMV IgG titers were observed in sera of SLE patients. Our data support the theory that EBV is notoriously associated with many autoimmune diseases. CMV appears to be associated to autoimmune diseases as well, yet establishing this theory requires further investigation.

Abstract
OBJECTIVE The present study prospectively investigated prevalence and features of thyroid cancer in patients with hepatitis C virus-related chronic hepatitis (HCV+) in comparison to two samples from the general population with different iodine intake. DESIGN We studied the prevalence of thyroid cancer in 308 unselected HCV+ patients in comparison to two population-based, gender- and age-matched control groups: 1) 616 subjects from an iodine deficient area; 2) 616 subjects from an iodine-sufficient area. Thyroid status was assessed by measurement of circulating thyroid hormones and autoantibodies, thyroid ultrasonography, and when indicated, fine-needle aspiration cytology. MAIN OUTCOME Circulating thyrotropin, anti-thyroglobulin, and anti-thyroperoxidase antibodies levels, and the prevalence of hypothyroidism were significantly higher in HCV+ patients (p < 0.001 for all). Six patients with papillary thyroid cancer were detected among HCV+ patients, whereas no case was observed in control 1 (p = 0.001), and only one case was observed in control 2 (p = 0.003). In HCV+ patients 83% with thyroid cancer had evidence of thyroid autoimmunity vs 31% of the other HCV+ patients (p = 0.02). CONCLUSIONS These data suggest a high prevalence of thyroid papillary cancer in HCV+ patients, overall in presence of thyroid autoimmunity; careful thyroid monitoring is indicated during the follow-up of these patients.

Abstract
PURPOSE OF REVIEW Cryoglobulinemic vasculitis is an immune-complex-mediated systemic vasculitis involving small-medium-sized vessels. A causative role of hepatitis C virus in over 80% patients has been definitively established, with heterogeneous geographical distribution. This review focuses on recent etiopathogenetic, clinico-diagnostic, and therapeutical studies. RECENT FINDINGS Hepatitis C virus cannot be integrated into the host genome; it may exert a chronic stimulus to the immune system. The interaction between hepatitis C virus envelope protein E2 with B-cell CD 81 receptor may increase the frequency of VDJ rearrangement in antigen-reactive B lymphocytes. One consequence is the activation of various protooncogenes, including anti-apoptotic Bcl-2. The extended B-cell survival is responsible for autoantibody and immune-complex production, including mixed cryoglobulins; some malignancies, mainly B-cell lymphomas, may complicate cryoglobulinemic vasculitis. Environmental or viral/host genetic cofactors should be relevant in the pathogenesis of hepatitis C virus-related diseases. Cryoglobulinemic vasculitis may overlap with other diseases (systemic vasculitides, Sjögren's syndrome, autoimmune hepatitis, lymphoma), which should be carefully considered for a correct diagnosis and treatment. Cumulative survival of cryoglobulinemic vasculitis is significantly lower compared with the general population. Therapeutic strategies for cryoglobulinemic vasculitis include etiologic (antiviral), pathogenetic (cyclophosfamide, rituximab), or symptomatic (steroids, plasmapheresis) treatments, which should be tailored to the individual patient according to the severity/activity of clinical symptoms. SUMMARY Cryoglobulinemic vasculitis represents a crossroads among autoimmune and lymphoproliferative disorders; as hepatitis C virus infection is the major causative factor, cryoglobulinemic vasculitis is an important model for etiopathogenetic studies of virus-related diseases.

Abstract
Hepatitis C virus (HCV) binding to hepatocytes is thought to be mediated via interaction of the E2 glycoprotein with (co-)receptors including CD81 and scavenger receptor class B type I (SR-BI). Here, the expression of CD81 and SR-BI was analysed on peripheral blood mononuclear cell (PBMC) subsets, and the binding of genotype 1 soluble truncated E2 (sE2) proteins to these cells was investigated. All PBMC subsets expressed CD81, although at varying levels. In contrast, SR-BI was only detected on monocytes and dendritic cells (DCs). The genotype 1a H77c sE2 protein showed higher PBMC binding than other genotype 1a/b sE2s. H77c sE2 binding to different PBMC subsets largely paralleled their level of CD81 expression, and could be inhibited by blocking E2–CD81 interaction. However, those PBMC subsets reported to be infected by HCV in vivo (monocytes, DCs and B cells) also exhibited residual, CD81-independent binding, indicating roles for SR-BI/other receptor(s) in mediating haematopoietic cell infection.

Abstract
AIM: To determine the prevalence of several autoantibodies in chronic hepatitis C patients, and to find out whether the pattern of autoantibodies was associated with hepatitis C virus (HCV) genotypes.
METHODS: Sera from 90 consecutive patients with chronic hepatitis C were investigated on the presence of anti-nuclear (ANA), anti-mitochondrial (AMA), anti-smooth muscle (SMA), anti-liver-kidney microsomal type 1 (LKMA1), anti-parietal cell (PCA), anti-thyroid microsomal (TMA), and anti-reticulin (ARA) autoantibodies. The autoantibodies were identified by indirect immunofluorescence. HCV genotypes were determined by a restriction fragment length polymorphism analysis of the amplified 5’ noncoding genome region.
RESULTS: Forty-six (51.1%) patients were positive for at least one autoantibody. Various antibodies were presented as follows: ANA in 13 (14.4%) patients, SMA in 39 (43.3%), TMA in 2 (2.2%), and ARA in 1 (1.1%) patients. In 9 cases, sera were positive for two autoantibodies (ANA and SMA). AMA, PCA and LKMA1 were not detected in the observed sera. HCV genotypes were distributed as follows: 1b in 66 (73.3%) patients, 3a in 18 (20.0%), and 2a in 6 (6.7%) patients.
CONCLUSION: A high prevalence of ANA and SMA can be found in chronic hepatitis C patients. Autoantibodies are present at low titre (1:10) in most of the cases. Distribution of the autoantibodies show no differences in the sex groups and between patients infected with different HCV genotypes.

Abstract
Visceral leishmaniasis may present with cytopenias along with the formation of many autoantibodies and, rarely, with the presence of mixed cryoglobulinemia, type II, resembling an autoimmune disease. The syndrome of mixed cryoglobulinemia is characterized by the triad of purpura, arthralgias, and asthenia, in conjunction with cryoglobulins in the serum. In this article mixed cryoglobulinemia, type II, was diagnosed in a negative for hepatitis B or C patient suffering from visceral leishmaniasis. Antimicrobial therapy against leishmania eliminated the cryoglobulin titer, as well as the clinical manifestations of cryoglobulinemia. The role of the immune system and the type of immune response for the formation of cryoglobulins are discussed.

Abstract
BACKGROUND Mixed cryoglobulinaemia (MC), a systemic vasculitis associated with hepatitis C virus (HCV) infection in >90% of cases, is frequently complicated by multiple organ involvement. The prevalence of thyroid disorders in MC has not yet been studied. AIM To investigate the prevalence and clinical features of thyroid involvement in patients with HCV-associated MC (HCV + MC). DESIGN Case-control study. METHODS HCV + MC patients (n = 93, 17 men and 76 women, mean +/- SD age 63 +/- 10 years, mean disease duration 14 +/- 7 years) consecutively referred to the Rheumatology Unit were matched by sex and age (+/- 2 years) to (i) 93 patients with chronic C hepatitis (CH) without MC and (ii) 93 healthy (HCV-negative) controls from the local population. Measurements included prevalence of hypo- or hyperthyroidism, thyroid autoantibodies, thyroid nodules and thyroid cancer. RESULTS By McNemar's chi(2) test, the following thyroid abnormalities were significantly more frequent in HCV + MC patients than in HCV-negative controls: serum anti-thyroperoxidase autoantibody (AbTPO) (28% vs. 9%, p = 0.001); serum AbTPO and/or anti-thyroglobulin autoantibody (31% vs. 12%, p = 0.004); subclinical hypothyroidism (11% vs. 2%, p = 0.038); thyroid autoimmunity (35% vs. 16%, p = 0.006). Serum AbTPO were also significantly more frequent in HCV + MC patients than in CH controls (28% vs. 14%, p = 0.035). DISCUSSION The prevalence of thyroid disorders is increased in patients with HCV-related mixed cryoglobulinaemia. We suggest careful monitoring of thyroid function in these patients.

Abstract
PURPOSE To explore the association of hepatitis C virus (HCV) infection with thyroid disorders. METHODS We investigated the prevalence of thyroid disorders in 630 consecutive patients with chronic hepatitis due to HCV infection; all patients were free of cirrhosis and hepatocarcinoma, and were not on interferon treatment. Also included were a control group of 389 subjects from an iodine-deficient area, another control group of 268 persons living in an area of iodine sufficiency, and 86 patients >40 years of age with chronic hepatitis B. Levels of thyroid-stimulating hormone (TSH), free thyroxine (T(4)), and triiodothyronine (T(3)), as well as anti-thyroglobulin and anti-thyroid peroxidase antibodies, were measured. RESULTS Mean TSH levels were higher (P = 0.001), and free T(3) and free T(4) levels were lower (P <0.0001), in patients with chronic hepatitis C than in all other groups. Patients with chronic hepatitis C were more likely to have hypothyroidism (13% [n = 82]), anti-thyroglobulin antibodies (17% [n = 108]), and anti-thyroid peroxidase antibodies (21% [n = 132]) than were any of the other groups. CONCLUSION Both hypothyroidism and thyroid autoimmunity are more common in patients with chronic hepatitis C-even in the absence of cirrhosis, hepatocellular carcinoma, or interferon treatment-than in normal controls or those with chronic hepatitis B infection.

Abstract
OBJECTIVE Review of relapsing polychondritis (RP) and its association to chronic hepatitis C virus (HCV) infection and mixed cryoglobulinemia. METHODS A case of RP associated with HCV infection is reported. The English language medical and scientific literature was reviewed for RP, hepatitis C, and its relation to other connective tissue diseases from February 1966 to January 2003 using MEDLINE. RESULTS RP is an uncommon, multisystem disease of unknown etiology characterized by recurrent inflammation of cartilaginous and related tissues, being associated with other diseases in 30% to 35% of cases. HCV infection is a systemic illness with a propensity to trigger or exacerbate autoimmune disorders: eg, essential mixed cryoglobulinemia, membranoproliferative glomerulonephritis, and leukocytoclastic and systemic vasculitis. We could find no previous report of an association between RP with HCV and mixed cryoglobulinemia. Treatment with interferon gamma and ribavirin (IR) not only induced an undetectable viral load, but also resolved symptoms of RP. CONCLUSIONS We report a patient with RP, HCV, and mixed cryoglobulinemia. It is unknown if there is a cause-effect or chance relationship. Treatment with IR improved the symptoms of RP. It is not known whether the effects of IR were directly on the RP or suppressed RP indirectly through the actions on the viral load or active hepatitis.

Abstract
BACKGROUND AND AIMS Hepatitis C virus infection is often associated with lymphoproliferative disorders such as essential mixed cryoglobulinemia and B-cell non-Hodgkin lymphoma, which show preferential expression of VHI family products. By analyzing immunoglobulin heavy chain usage, we addressed the question of whether or not clonal B-cell expansion occurrs in patients free of essential mixed cryoglobulinemia or non-Hodgkin lymphoma. PATIENTS AND METHODS Four hepatitis C virus-positive patients, all undergoing liver transplantation, were studied. Peripheral blood, intra-hepatic, and lymph node lymphocytes were used as a source of B cells. A patient with hepatocellular carcinoma and fresh blood from four healthy donors were used as negative controls. VHI family sequences were cloned and analyzed by reverse transcription-polymerase chain reaction. RESULTS Immunoglobulin heavy chain sequences from clonally expanded B lymphocytes were identified in three out of four hepatitis C virus-infected patients. The clonally expanded B lymphocyte populations showed a broad spectra of immunoglobulin heavy chain gene usage. CONCLUSIONS HCV infection can induce B-cell expansion with larger clonal variation. The restricted V gene usage in hepatitis C virus-associated non-Hodgkin lymphoma suggests that there may be selection mechanisms to develop non-Hodgkin lymphoma from non-malignant, clonally expanded B-cell populations in hepatitis C virus-infected patients.

We present a 75-year-old patient with recurrent palpable purpura and multiorgan involvement by leukocytoclastic vasculitis caused by mixed-type cryoglobulinemia. The disease spanned 40 years, with many flare-ups, each associated with thrombocytopenia, and finally culminated in widespread involvement of not only the skin and the kidneys but also the lungs and spleen. Despite extensive investigation, no association with hepatitis C virus or with any malignant or connective tissue disorder was found.

Abstract
Cutaneous eruptions related to hepatitis C virus (HCV), a major cause of hepatitis in the setting of blood transfusion, intravenous drug abuse, organ transplantation, and hemodialysis, are typically reported as isolated cases. We encountered 35 cases of HCV infection associated with cutaneous eruptions. The present study evaluates paraffin-embedded, formalin-fixed tissue sections stained with hematoxylin and eosin from biopsy specimens of skin lesions from 35 patients seropositive for HCV. In 20 cases, reverse transcriptase polymerase chain reaction (RT-PCR) was performed using a probe for HCV RNA; the RNA was detected through the action of alkaline phosphatase on the chromogen nitroblue tetrazolium and bromochloroindolyl phosphate. The clinical spectrum comprised dermatomyositis-like photodistributed eruptions, palpable purpura, folliculitis, violaceous and perniotic acral lesions, ulcers, nodules, and urticaria. Lesions were also classified histopathologically by the dominant reaction pattern: vasculopathies of neutrophilic, lymphocytic, and granulomatous vasculitis and pauci-inflammatory subtypes (15 patients); palisading granulomatous inflammation (3 patients); sterile neutrophilic folliculitis (5 patients); dermatitis herpetiformis (1 patient); lobular panniculitis composed of neutrophilic lobular panniculitis in 2 patients and benign cutaneous polyarteritis nodosa in 1 patient; neutrophilic dermatoses, including neutrophilic urticaria, neutrophilic eccrine hidradenitis, and pyoderma gangrenosum (3 patients); interface dermatitis (3 patients); and low-grade lymphoproliferative disease of B-cell lineage representing marginal zone lymphoma in 1 patient and a clonal plasmacellular infiltrate in another patient. In most cases, whereas 1 of the aforementioned disorders defined the dominant reaction pattern, there was an accompanying secondary reaction pattern, defining a hybrid picture. Endothelial changes including endothelial cell enlargement and effaced heterochromatin with margination of the chromatin to the nuclear membrane were seen in several cases; in some cases similar cytopathic changes also involved the supporting pericytes, eccrine ductular cells, or keratinocytes. The RT-PCR analyses in 8 of 20 cases examined revealed HCV RNA expression in a focal, weak fashion in endothelia and perivascular inflammatory cells in those cases showing vasculopathic changes. Viral parasitism of endothelia may be important in cutaneous lesional propagation in the setting of HCV infection. Cross-reactivity between endogenous and viral antigens, leading to cellular and/or type II immune reactions; viral tropism to B lymphocytes, resulting in B cell expansion with resultant autoantibody production; and circulating immune complexes containing monoclonal cryoglobulins may also be of pathogenetic importance. Tropism of the virus to B lymphocytes provides a mechanism for the development of low-grade clonal B cell lymphoproliferative disease in this setting.

Abstract
Hepatitis C virus (HCV) affects 1.8% of the American population, and approximately 38% of patients with HCV will manifest symptoms of at least 1 extrahepatic manifestation during the illness. Renal disease, neuropathy, lymphoma, and Sjögren syndrome with or without mixed cryoglobulinemia are all strongly associated with HCV infection. Porphyria cutanea tarda and diabetes have also been linked to HCV. Most extrahepatic manifestations of chronic HCV infection are immunological, and the chronic infection seems to be necessary for their development. The molecular study of the unique way in which the HCV virus interacts with the human immune system is beginning to provide plausible explanations of the pathogenic role of HCV in some of these syndromes, but many pathogenetic links remain completely obscure.

Abstract
Abnormalities of LFTs and liver function occur not infrequently in patients with rheumatic conditions, and many diagnostic possibilities exist. Systemic inflammation that is related to uncontrolled rheumatic disease and periods of disease remission have been described as a cause for fluctuations in levels of serum aminotransferases. Although these benign extra-articular manifestations of rheumatic disease are the most common manifestations, more serious hepatic involvement, including vasculitis, nodular regenerative hyperplasia, and primary biliary cirrhosis, have been observed in specific rheumatic diseases. The cause of rheumatic disease is unclear. Occult HCV infection and associated cryoglobulinemia can mimic rheumatic disease. HCV infection should be suspected routinely in patients with mixed cryoglobulinemia, especially because antiviral therapy may be beneficial. The medical management of rheumatic disease involves medications that are often hepatotoxic. Routine laboratory monitoring, imaging studies, and, if necessary, biopsy examination in situations in which serum aminotransferases remain abnormal, are recommended.

Abstract
CONTEXT Fibromyalgia is a disorder that is appearing more and more in the clinical practice but is poorly understood. OBJECTIVE This paper attempts to look at all available and reliable data on these conditions and will outline current, scientifically sound understanding of these disorders, treatment modalities and future directions for research. It also attempts to analyze the social and cultural implications. DATA SOURCES/STUDY SELECTION Various terms used to describe these syndromes are fibromyalgia (FMS), and myalgic encephalomyelitis (ME). PubMed search was performed. Pertinent articles published in past 25 years and The National Academy of Sciences colloquium on Neurobiology of Pain was also reviewed. In addition, news-articles in the lay press as well as the Internet were monitored for material posted by sufferers of these disorders. DATA EXTRACTION Studies were reviewed for clinical presentations, history of these disorders, comorbid conditions, etiology, biochemical and microbiologic abnormalities, abnormalities found on neuroimaging and functional neurophysiologic techniques. In addition patient postings on the Internet and articles appearing in lay press were reviewed and social implications are discussed. DATA SYNTHESIS Upon analysis of these materials the review was organized based on the quality of data and it's contextual scientific, cultural and political meaning for this disorder. This review appears to be pointing towards an entirely new paradigm in pain disorders; therefore, a hypothesis and future direction of research is repeatedly suggested. CONCLUSION This study proposes an entirely new paradigm in these disorders based on scientific and cultural data.

Abstract
Viruses are considered as causative agents and contributors to lesion expression in autoimmune disease, notions best supported by studies in animal model systems. This review discusses relationships between virus infection and autoimmunity focusing on mechanisms by which they could induce autoreactivity. The popular idea of molecular mimicry is viewed skeptically with the reviewers taking the viewpoint that viruses contribute to autoimmunity mainly by inducing several nonspecific inflammatory events that together are sufficient to trigger autoreactivity in genetically receptive hosts.

Abstract
Removal of cryoglobulins by plasma exchange is now an accepted therapy. Cryoglobulins are circulating complexes that can deposit on small vessels and cause limited or extensive tissue injury. There are 3 major classes of cryoglobulins. Type I cryoglobulins are monoclonal and are detected in a variety of lymphoproliferative disorders. Type II cryoglobulins are mixed containing monoclonal and polyclonal IgG or IgM molecules. Type III cryoglobulins are also mixed and contain polyclonal IgG. Type II cryoglobulins are largely caused by hepatitis C virus infection; hence, they are the most common of the 3 types. In hepatitis C, cryoglobulins are linked to glomerular immune complex injury, often times accompanied by vasculitis of the skin, nerves, and other vital organs. Immediate removal of cryoglobulins by plasma exchange is an effective short-term treatment that can complement more-specific therapies. Plasma exchange has also been used to remove other circulating nephrotoxic agents such as antiglomerular basement antibodies that cause Goodpasture's syndrome, protease inhibitor autoantibodies that cause thrombotic thrombocytopenic purpura, and antiglomerular factors that cause some types of focal glomerulosclerosis.
