Post-Treatment Occurrence of Serum Cryoglobulinemia in Chronic Hepatitis C Patients. Diagnostics (Basel) 2024; 14:1188. [PMID: 38893714 PMCID: PMC11171999 DOI: 10.3390/diagnostics14111188] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2024] [Revised: 05/21/2024] [Accepted: 05/24/2024] [Indexed: 06/21/2024] Open
Abstract
BACKGROUND Persistent cryoglobulinemia after the completion of antiviral treatment is an important consideration of clinical management in chronic hepatitis C patients. We aimed to investigate the occurrence of serum cryoglobulinemia in chronic hepatitis C patients without cryoglobulinemia at the initiation of antiviral treatment. METHODS In total, 776 patients without cryoglobulinemia were assessed for serum cryoglobulinemia after the completion of anti-HCV treatment. Serum cryoglobulinemia precipitation was assessed upon both the initiation and the completion of the treatment and analyzed for the clinical laboratory factors associated with chronic hepatitis C. RESULTS One hundred eighteen (118) patients were checked for serum cryo-precipitation after the completion of the treatment, and eight patients (4.6%) were positive for serum cryoglobulinemia. The patients who tested positive for cryoglobulinemia included a higher proportion of liver cirrhosis patients (4/50%, p = 0.033) and other organ cancer patients (5/62.5%, p = 0.006) than patients who showed no signs of cryoglobulinemia after treatment. In a multivariate analysis, liver cirrhosis (odds ratio [OR]-17.86, 95% confidence interval [95% CI]-1.79-177.35, p = 0.014) and other organ cancer (OR-25.17 95% CI-2.59-244.23, p = 0.005) were independently and significantly associated with positive cryoglobulinemia 3 months after antiviral treatment. CONCLUSIONS Three months after the antiviral DAA therapy had concluded, eight patients tested positive for cryoglobulinemia, representing a 6.7% prevalence. Liver cirrhosis and other organ cancer were independently and significantly associated with positive cryoglobulinemia after antiviral treatment. Further investigation into the causes of positive cryoglobulinemia after DAA antiviral therapy is warranted.

Abstract
Cryoglobulinemia is defined by the presence of immunoglobulins having the following characteristics: forming a gel when temperature is <37 °C, precipitate in a reversible manner in the serum, and redissolve after rewarming. The presence of both polyclonal IgG and monoclonal IgM (type II), or of polyclonal IgG and polyclonal IgM (type III) identifies the mixed cryoglobulinemia (MC). The identification of the Hepatitis C virus (HCV) infection in most of the cases previously defined as "essential" represented a cornerstone in the understanding the pathogenesis of this condition. The picture of MC comprehends heterogeneous clinical presentations: from arthralgias, mild palpable purpura, fatigue to severe vasculitis features with skin necrotic pattern, peripheral neuropathy and, less commonly, lungs, central nervous system, gastrointestinal tract, and heart involvement. The kidney represents the most common organ presentation, and the presence of glomerulonephritis is a key element when considering prognosis. We discuss the clinical presentation and histological features, diagnostic pitfalls, and controversies in the management of patients with cryoglobulinemic glomerulonephritis, with a special focus on reporting our experience in treating patients with B cell depletion therapy.

Abstract
BACKGROUND AND STUDY AIMS Hepatitis C virus (HCV)-related cirrhosis is the leading cause of liver transplantation (LT). All patients who undergo LT with detectable serum HCV-RNA experience graft reinfection, which is the most frequent cause of graft loss and death in these patients. We estimated the rate of HCV recurrence and evaluated the current therapeutic regimens. PATIENTS AND METHODS The records of consecutive 325 living donor LT (LDLT) surgeries performed between May 2004 and August 2014 were retrospectively analysed; 207 of them were followed-up throughout the study. Clinical, laboratory, radiological and histopathological examinations were performed thoroughly. Patients received treatment in the form of either pegylated interferon (PEG-IFN) or sofosbuvir, both in combination with ribavirin. RESULTS In total, 90.3% of recipients who were transplanted because of HCV-related end-stage liver disease experienced recurrence due to the virus. The donor age was older in the HCV recurrent group versus the non-recurrence group (28.7±7.1 versus 22.6±2.6years: p≤0.001), warm ischaemia time was prolonged (46.1±18.1 versus 28.6±4.1min: p≤0.001), median cold ischaemia time was 40.0 (10-175) versus 22.5 (15-38) min (p≤0.001) and basal PCR was 414000 (546-116000000) versus 10766 (1230-40000) (p≤0.001). Sustained virological response was achieved in 95.4% of patients treated with a combination of a fixed daily dose of 400mg sofosbuvir with ribavirin and in 65.1% of those who were treated with PEG-IFN with ribavirin. CONCLUSIONS Older donor age and prolonged warm ischaemia time are independent predictors of HCV recurrence after LDLT, and early treatment with the direct-acting sofosbuvir is helpful in resolving the problem of post-LT HCV recurrence.

Abstract
Hepatitis C virus (HCV) is both hepatotrophic and lymphotropic virus that causes liver as well extrahepatic manifestations including cryoglobulinemic vasculitis, the most frequent and studied condition, lymphoma, and neurologic, cardiovascular, endocrine-metabolic or renal diseases. HCV-extrahepatic manifestations (HCV-EHMs) may severely affect the overall prognosis, while viral eradication significantly reduces non-liver related deaths. Different clinical manifestations may coexist in the same patient. Due to the variety of HCV clinical manifestations, a multidisciplinary approach along with appropriate therapeutic strategies are required. In the era of interferon-free anti-HCV treatments, international recommendations for the therapeutic management of HCV-EHMs are needed. This implies the need to define the best criteria to use antivirals and/or other therapeutic approaches. The present recommendations, based on qualified expert experience and specific literature, will focus on etiological (antiviral) therapies and/or traditional pathogenetic treatments that still maintain their therapeutic utility.

Abstract
BACKGROUND Hepatitis C infection is a major health problem worldwide, especially in Egypt. The high prevalence of mixed cryoglobulinemia (MC) in hepatitis C patients leads to the assumption that there is a direct link between hepatitis C virus (HCV) and cryoglobulinemia. Host genetic factors could be a contributing factor. B cell-activating factor (BAFF) is a tumor necrosis factor (TNF) family member, which has an essential role in B lymphocyte development and survival. The aim of the present work was to study the possible association between the BAFF -871C/T promoter polymorphism and HCV-related MC in a cohort of Egyptian patients. METHODS The study was conducted in 120 HCV patients classified into two groups: group I (60 HCV patients with MC) and group II (60 HCV patients without MC), with 60 age- and sex-matched healthy control subjects. BAFF -871C/T genotyping was performed in all subjects by polymerase chain reaction (PCR) with restriction fragment length polymorphism analysis. RESULTS The prevalence of the BAFF -871TT genotype was significantly increased in HCV patients compared with the control group (P=0.036). The BAFF TT genotype was also significantly more prevalent in group I (HCV-MC patients) than in group II (HCV patients without MC) [P<0.001]. CONCLUSION A significant association was found between the BAFF -871C/T promoter polymorphism and MC, which may indicate that BAFF could be a potential therapeutic target in HCV-MC.

Abstract
BACKGROUND Peripheral neuropathy is the most common neurologic complication of hepatitis C virus (HCV) infection. The pathophysiology of the neuropathy associated with HCV is not definitively known; however, proposed mechanisms include cryoglobulin deposition in the vasa nervorum and HCV-mediated vasculitis. The optimal treatment for HCV-related peripheral neuropathy has not been established. OBJECTIVES To assess the effects of interventions (including interferon alfa, interferon alfa plus ribavirin, corticosteroids, cyclophosphamide, plasma exchange, and rituximab) for cryoglobulinemic or non-cryoglobulinemic peripheral neuropathy associated with HCV infection. SEARCH METHODS On 26 August 2014, we searched the Cochrane Neuromuscular Disease Group Specialized Register, CENTRAL, MEDLINE, and EMBASE. We also searched two trials registers, the Networked Digital Library of Theses and Dissertations (NDLTD) (October 2014), and three other databases. We checked references in identified trials and requested information from trial authors to identify any additional published or unpublished data. SELECTION CRITERIA We included all randomized controlled trials (RCTs) and quasi-RCTs involving participants with cryoglobulinemic or non-cryoglobulinemic peripheral neuropathy associated with HCV infection. We considered any intervention (including interferon alfa, interferon alfa plus ribavirin, corticosteroids, cyclophosphamide, plasma exchange, and rituximab) alone or in combination versus placebo or another intervention ('head-to-head' comparison study design) evaluated after a minimum interval to follow-up of at least six months. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by The Cochrane Collaboration. The planned primary outcome was change in sensory impairment (using any validated sensory neuropathy scale or quantitative sensory testing) at the end of the follow-up period. Other planned outcomes were: change in impairment (any validated combined sensory and motor neuropathy scale), change in disability (any validated disability scale), electrodiagnostic measures, number of participants with improved symptoms of neuropathy (global impression of change), and severe adverse events. MAIN RESULTS Four trials of HCV-related cryoglobulinemia fulfiled selection criteria and the review authors included three in quantitative synthesis. All studies were at high risk of bias. No trial addressed the primary outcome of change in sensory impairment. No trial addressed secondary outcomes of change in combined sensory and motor impairment, disability, or electrodiagnostic measures. A single trial of HCV-related mixed cryoglobulinemia treated with pegylated interferon alfa (peginterferon alfa), ribavirin, and rituximab versus peginterferon alfa and ribavirin did not show a significant difference in the number of participants with improvement in neuropathy at 36 months post treatment (risk ratio (RR) 4.00, 95% confidence interval (CI) 0.27 to 59.31, n = 9). One study of interferon alfa (n = 22) and two studies of rituximab (n = 61) provided adverse event data. Severe adverse events were no more common with interferon alfa (RR 7.00, 95% CI 0.38 to 128.02) or rituximab (RR 3.00, 95% CI 0.13 to 67.06) compared to the control group. AUTHORS' CONCLUSIONS There is a lack of RCTs and quasi-RCTs addressing the effects of interventions for peripheral neuropathy associated with HCV infection. At present, there is insufficient evidence from RCTs and quasi-RCTs to make evidence-based decisions about treatment.

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
OBJECTIVE To examine the safety and efficiency of using Peg-IFNα2a/ribavirin and low-dose NSAID therapy in patients with rheumatoid syndrome (RS) and chronic hepatitis C (CHC). METHODS A group of 10 patients (group 1) known to have RS and established CHC undergoing Peg-IFNα2a/ribavirin and low-dose NSAID therapy was compared with a control group of 10 patients (group 2) also with CHC and associated RS, with no antiviral treatment. Their charts were reviewed for serological and clinical signs of rheumatic disease evolution while undergoing this type of treatment. RESULTS At the end of a follow-up period of 12 months, patients receiving low-dose NSAID and Peg-IFNα2a/ribavirin therapy showed a sustained virusological response and also decreased levels of inflammation serological markers, with an improvement in the clinical rheumatic symptoms. In contrast, patients in group 2 showed no significant clinical modification in their rheumatic status. CONCLUSION Peg-IFNα2a/ribavirin and low-dose NSAID in patients with RS and CHC appear to be well tolerated and can be efficient for rheumatic manifestations. Further controlled studies are required to confirm the results.

Abstract
Mixed cryoglobulinemia (MC) is a syndrome resulting from cold-insoluble immunoglobulin complexes or cryoglobulins (CGs) that precipitate in the serum of 40% to 50% of patients with chronic hepatitis C virus (HCV) infection. The pathogenesis of cryoglobulinemia likely occurs due to chronic viremia and generation of rheumatoid factor following continuous presentation of antigen-immunoglobulin complexes to B cells. CGs are thought to be responsible for a variety of extrahepatic manifestations associated with HCV, including vasculitis, glomerulonephritis, arthritis, and neuropathies, which occur in approximately 10% of HCV patients with CGs. CGs also are a powerful predictive factor for progressive liver disease and the aggressive reoccurrence of liver disease in HCV-positive patients after liver transplantation. First-line therapy for MC due to HCV infection is antiviral therapy with pegylated interferon-alpha and ribavirin. Viral eradication usually produces marked reduction of physical complications and arrests end organ damage concomitant with clearance of CG. Additional prospective, controlled studies are necessary to determine whether CG influences patient virologic response and/or its durability to antiviral therapy. Immunomodulators such as corticosteroids and cyclophosphamide are efficacious for palliative treatment of the symptomatology of HCV cryoglobulinemia but may enhance viral replication. Consequently, prolonged therapy with immunomodulatory agents should be limited to severe vasculitis or aggressive glomerulonephritis in patients with MC due to HCV who have failed to respond to antiviral therapy. In acute, fulminant presentations, plasmapheresis may provide temporary relief and arrest the rapid progression of the disease so that additional therapy can be initiated.

Abstract
Chronic kidney disease (CKD) is becoming a major public health issue worldwide, mainly due to the increasing prevalence of hypertension, diabetes and aging population. Chronic hepatitis C virus (HCV) infection commonly involves the kidneys, can be a cause of CKD, and significantly impacts morbidity and mortality in these patients. Prompt recognition and knowledge of how to best manage these patients are essential in order to have a successful renal outcome. Patients with HCV and kidney involvement can often be managed with a specific combination of antiviral drugs, immunosuppressants, plasmapheresis, and newer monoclonal antibodies. However, no large randomized controlled trials have been conducted in this patient population, optimal management of HCV-mediated kidney diseases is not well defined, and treatment itself can be associated with significant toxicity in patients with CKD. This article reviews the recent literature, discusses the limitations of current therapies, as well as toxicity associated with treatment, and suggests future areas for research.

Abstract
Previous reports suggest cryoglobulinemia might influence the hepatitis C virus (HCV) infection clinical course and treatment response but this association has not been thoroughly evaluated. We aimed to assess the relationship between cryoglobulinemia and sustained viral response (SVR) in patients treated for HCV infection. We included patients with HCV infection treated from January 2003 through December 2006. Biochemical analyses, detection cryoglobulinemia, and liver biopsies were performed prior to treatment. Genotype 1 or 4 infections received Peg-interferon (IFN) alpha-2a or -2b for 48 weeks; genotypes 2 or 3 received IFN alpha for 24 weeks. All patients also received ribavirin. Of 329 enrolled patients, 242 (73%) were male and the median age was 43 years. Cryoglobulinemia was detected in 196 (59.6%) patients; liver biopsy was performed in 301. Multivariate analysis showed an association of cryoglobulinemia with severe active necroinflammation (A3) (adjusted odds ratio [AOR] = 9.48; 95% confidence interval [CI]: 1.50-59.92) and rheumatoid factor (RF) level (AOR = 1.01; 95% CI: 1.00-1.02). Variables associated with advanced fibrosis were age, aspartate aminotransferase and alkaline phosphatase levels, alcohol use, and presence of diabetes. Variables independently associated with SVR were cryoglobulinemia (AOR = 2.33, 95% CI: 1.26-4.32), absence of cirrhosis (AOR = 4.5, 95% CI: 1.4-14.80), and RF level (AOR = 1.008, 95% CI: 1.001-1.014). Our findings suggest cryoglobulinemia is associated with severe necroinflammatory activity in HCV-infected patients. We also provide the first evidence for an association between cryoglobulinemia and higher SVR rates, highlighting its potential role as a prognostic factor for treatment response.

Abstract
Mixed cryoglobulinemia is a chronic immune complex-mediated disease strongly associated with hepatitis C virus (HCV) infection. Mixed cryoglobulinemia is a vasculitis of small and medium-sized arteries and veins, due to the deposition of complexes of antigen, cryoglobulin and complement in the vessel walls. The main clinical features of mixed cryoglobulinemia vasculitis include the triad of palpable purpura, arthralgias, and weakness, and other pathological conditions such as glomerulonephritis, peripheral neuropathy, skin ulcers, and widespread vasculitis. The treatment of HCV-related mixed cryoglobulinemia is difficult due to the multifactorial origin and clinical polymorphism of the syndrome. It can be directed to eradicate the HCV infection, suppress the B-cell clonal expansion and cryoglobulin production, or ameliorate symptoms. The choice of the most appropriate treatment is strictly related to the assessment of disease activity, and to the extent and severity of organ involvement.

Abstract
In this review we discuss the clinical manifestations, pathogenesis, and treatment of hepatitis C virus (HCV)-related cryoglobulinemia. HCV is a major cause of liver-related morbidity and is increasingly recognized as an instigator of B-cell lymphoproliferative disorders such as mixed cryoglobulinemia and non-Hodgkin lymphoma. Cryoglobulinemia is characterized by the clonal expansion of rheumatoid factor-expressing B cells in the liver, lymph nodes, and peripheral blood, resulting in the presence of cryoglobulins in the circulation. Cryoglobulins are cold-insoluble immune complexes containing rheumatoid factor, polyclonal IgG, and HCV RNA that precipitate and deposit on vascular endothelium, causing vasculitis in organs such as the skin, kidneys, and peripheral nerves. A subset of patients develops a low-grade lymphoma composed of B cells that are immunophenotypically similar to the expanded B cells seen in cryoglobulinemia. HCV-related B-cell lymphoproliferative disorders likely comprise a spectrum of disease, ranging from asymptomatic clonal B-cell expansions to pathogenic cryoglobulinemia and lymphoma. It is unclear how B cells become dysregulated during the course of chronic HCV infection, and continued patient-centered research is necessary to elucidate the pathogenesis of HCV-related B-cell dysregulation.

Abstract
Mixed cryoglobulins are detected in 50% of patients with hepatitis C; fortunately, few have vasculitis affecting skin, peripheral nerves, kidneys, and synovia. This study was designed to identify the natural history of symptomatic cryoglobulinemia and evaluate the response to antiviral therapy. Patients with hepatitis C complicated by symptomatic cryoglobulinemia were assessed for their disease manifestations and response to antiviral therapy. Of 83 patients identified, 56 patients with a minimum of 12 months follow-up were reviewed. Manifestations included dermatologic (75%), rheumatologic (57%), neurologic (34%), and renal (proteinuria 25%). Antiviral therapy was given to 38, of whom 9 were retreated for symptomatic and/or virological nonresponse. Antiviral therapy included interferon monotherapy (n= 8), pegylated-interferon monotherapy (n= 5), consensus-interferon (n= 2), interferon + ribavirin (n= 18), and pegylated-interferon + ribavirin (n= 14). Treatment provided sustained symptomatic response in 31 (82%) and virological response in 16 (42%) patients. Symptomatic cryoglobulinemia responds well to antiviral therapy, even when virological response is not achieved.

Abstract
INTRODUCTION: The main extra-hepatic manifestation of hepatitis C is mixed cryoglobulinemia (MC). The aim of this study was to evaluate its prevalence among patients with chronic hepatitis C (CHC), to correlate its presence to host and virological variables and to the response to combined therapy with interferon-alpha and ribavirin. CASUISTIC AND METHODS: 202 CHC naive patients (136 with chronic hepatitis and 66 with cirrhosis) were consecutively evaluated for the presence of cryoglobulins. Cryoprecipitates were characterized by immunoelectrophoresis and classified according to the Brouet's criteria. RESULTS: The prevalence of MC was 27% (54/202), and 24% of them (13/54) showed major clinical manifestation of the disease. Even though type III MC was more frequent (78%), symptomatic MC was more common in type II MC. The presence of cirrhosis (RR = 2.073; IC95% = 1.029 - 4.179; p = 0.041), and age of the patients (RR = 1.035; IC95% = 1.008 - 1.062; p = 0.01) were independently associated with the presence of cryoglobulins. No relationship was found with viral load and genotype. 102 patients were treated with interferon alpha and ribavirin. Among these, 31 had MC. Sustained virological response (around 30%) was similar in patients with and without MC (p = 0.971). CONCLUSION: MC represents a prevalent complication in patients with CHC, specially older and cirrhotic patients. Only 24% of these patients show clinical manifestation of the disease, specially those with type II MC. The presence of MC did not affect the response to therapy.

Abstract
BACKGROUND Homocysteine, an independent risk factor for thromboembolism, has been recently shown to be elevated in ulcerative colitis (UC). However, its relation to the activity of the disease remain unclear. METHODS Two groups were studied: group consisted of 1-30 patients with UC (17 men, 13 women, mean age 50.3 +/- 14.7 years), including 15 patients with active disease. Group 2 (controls) consisted of 21 age-, sex-, bodyweight-matched healthy persons (12 men, nine women, mean age 53.1 +/- 12.8 years). Total plasma homocysteine (tHcy) and serum folate and vitamin B12 as well as selected coagulation parameters were assessed. RESULTS Mean tHcy in UC patients was significantly higher than in healthy controls: 10.8 +/- 3.1 mmol/L versus 6.8 +/- 2.5 mmol/L (P < 0.001). Patients with active disease had higher tHcy than patients in remission: 11.2 +/- 3.5 mmol/L versus 9.0 +/- 2.3 mmol/L (P = 0.048). Patients with > or =4 recurrences of the disease had also higher tHcy than the others: 11.5 +/- 3.6 mmol/L versus 9.0 +/- 2.1 mmol/L (P = 0.035). The tHcy correlated with duration of disease: r = 0.6632 (P < 0.05). Folate and B12 levels were within their reference ranges in all subjects. However, in the patients with active disease the platelet count, fibrinogen and D-dimer were significantly higher than in the patients in remission and the controls. CONCLUSIONS Ulcerative colitis is associated with elevated tHcy concentration, particularly in the active stage, and in more recurrent types of the disease; this elevation does not seem to be prevented by a normal folate status and might have an enhancing effect on the procoagulation blood profile.

Abstract
Hepatitis C virus (HCV) plays a major role in the induction of type II mixed cryoglobulinaemia (MCII). The role of HCV proteins and virus-host interaction in the pathogenesis of MC remains to be defined. To address this issue, we have characterized, in detail, the monoclonal IgM and the viral component of circulating immune complexes in eight patients with HCV-associated MCII. The proportion of HCV-RNA compartmentalized in the cryoprecipitate (CP) varied greatly (10-80% of total HCV-RNA). The complementary determining region (CDR)3 sequences of monoclonal immunoglobulin M (IgM) VH and VK genes were highly homologous to rheumatoid factor and to antibodies against HCV-E2. Furthermore, the CDR3 sequences in some of our MCII patients were highly similar to those described in HCV-positive patients with non-Hodgkin's lymphoma (NHL). From these results, it appears that, as in the case of NHL, the IgM-rheumatoid factor (RF) production in MCII patients is antigen driven, namely by E2. However, the limited number of mutations in VH and VK genes with respect to the germline and their distribution showed that the B-cell response in these cases was prevented from undergoing affinity maturation. Furthermore, in patients with monoclonal IgM and definite compartmentalization of HCV in either CP or supernatant, a highly homogeneous E2-hypervariable region (HVR)1 sequence distribution was found (90-100% identical clones), a feature of the quasispecies frequently associated with an impaired humoral immune response to HCV. These findings suggest that in patients with HCV-associated MCII, maturation of monoclonal B lymphocytes may be blocked in a primitive stage preventing serious damaging effects because of the auto-reactivity of their secreted immunoglobulins.

Abstract
BACKGROUND Recurrent hepatitis C virus (HCV) infection in patients after liver transplantation is an important clinical problem. Because serum cryoglobulins (CG) are known to be associated with an increased incidence of cirrhosis in nontransplant patients, the authors tested the hypothesis that CG would also predict aggressive recurrent HCV in patients after liver transplantation. METHODS Using a longitudinal database, the outcomes of 105 allografts transplanted into 97 HCV-positive patients from 1991 through 2002 were analyzed on the basis of CG status using a retrospective cohort design. Fifty-nine CG-negative and 38 CG-positive patients were identified. Histologic outcomes and graft survival were analyzed using Kaplan-Meier estimates and Cox univariate and multivariate analyses. Both overall survival and HCV-specific survival (non-HVC-related deaths and graft losses censored) were analyzed. RESULTS By Kaplan-Meier estimates, CG-positive patients showed earlier graft failure with decreased time to severe histologic activity and fibrosis as compared with CG-negative patients (P<0.05 for all outcomes). By univariate analysis, CG-positive patients had significantly higher risk ratios for shortened HCV-specific graft survival, severe activity-free survival, and severe fibrosis-free survival as compared with CG-negative patients (P<0.05 for all outcomes). In the multivariate model, CG was an independent predictor for severe activity-free, severe fibrosis-free, and HCV-specific graft survival (P<0.05 for all outcomes). CONCLUSIONS CG-positivity is associated with severe recurrent HCV disease in liver transplant recipients.

Abstract
OBJECTIVES To evaluate hepatitis C virus (HCV)-positive patients followed in a rheumatology department and to compare them with a similar population of HCV-positive patients who had never seen a rheumatologist, in order to describe the rheumatological symptoms present and the effects of methotrexate and interferon-alpha therapy. METHODS We performed a retrospective study of clinical, radiological and biological data on 21 rheumatology patients (Group I) presenting symptoms consistent with a chronic inflammatory arthritis with a known HCV infection and compared them with 41 members of an HCV support association (Group II). RESULTS Symptoms of myalgia, sicca syndrome, Raynaud's phenomenon or paraesthesias were similarly frequent in the two groups. However, inflammatory joint pain and joint swelling were more common in Group I. In this group rheumatoid factor was positive in 48%, antinuclear antibodies in 26%, cryoglobulin in 44% and a reduced complement level in 63%. The majority of patients from Group I treated with methotrexate demonstrated an amelioration of the rheumatological symptoms with few negative outcomes. Regarding interferon-alpha therapy and rheumatological symptoms-in Groups I and II respectively 50 and 66% demonstrated a deterioration, 33 and 30% showed no change and 17 and 4% showed an amelioration. CONCLUSION Rheumatological symptoms are common in patients chronically infected with HCV. It is essential to individualize the role of treatment with interferon-alpha and to consider the use of methotrexate for difficult cases.

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
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
The hepatitis C virus (HCV) infection is a worldwide disease that is characterized by a preferential chronic evolution with mild to severe liver disease, including cirrhosis and, in lesser proportion, hepatocarcinoma. Out of these complications, HCV is frequently reported to complicate extrahepatic manifestations. Among those associated to HCV infection with a high degree of certainty, mixed cryoglobulinemia and its complications (skin, neurological, renal, rheumatological involvement) are the most prevalent (50%) in HCV-infected patients. The other diseases include noncryoglobulinemic systemic vasculitis, splenic lymphoma with villous lymphocytes, fatigue, porphyria cutanea tarda, sicca syndrome, and autoantibodies production. The extrahepatic manifestations that share mild-degree certainty of association with HCV infection include B-cell non-Hodgkin lymphoma, autoimmune thrombocytopenia, pruritus, and type II diabetes mellitus. The other diseases such as autoimmune thyroiditis, lichen planus are more questionable for their eventual association with HCV and others (pulmonary fibrosis with or without polymyositis, progressive encephalomyelitis, Mooren's corneal ulcers, erythema nodosum, chronic polyradiculonevritis) are mostly case reports. Howerver, even in cases of tight association, the mechanisms through which HCV may promote or induce extrahepatic manifestations remain unclear and merit further investigations.

Abstract
This article considers the extrahepatic manifestations associated with HBV and HCV infection, the strength of the evidence for the association, potential pathological mechanisms, and evidence based therapeutic recommendations. As many of these extra hepatic conditions are uncommon, published reports have been largely uncontrolled or anecdotal.

Abstract
A 49-year-old Japanese woman was diagnosed with rheumatoid arthritis (RA) based on ACR criteria in May 1999. She developed liver injury after initiation of disease-modifying antirheumatic drugs (DMARDs) and was found to have contracted HCV infection. RA disease activity worsened following restriction of medication due to liver dysfunction. However, 3 mg/day of prednisolone (PSL) resulted in a temporary but marked improvement of RA in December 2001; but arthritis recurred along with Raynaud's phenomenon and palpable purpura. Differential diagnosis between arthritis caused by cryoglobulinemia and exacerbation of RA was important for the selection of appropriate treatment. She manifested non-erosive arthritis on medium and large joints with proteinuria, hematuria and hypocomplementemia. In addition, type III cryoglobulin was detected and chronic active hepatitis was observed on liver biopsy in March 2002. We considered that the main cause for the arthritis was HCV-related mixed cryoglobulinemia. Administration of IFN-alpha resulted in the disappearance of HCV-RNA and cryoglobulin followed by amelioration of arthritis without exacerbation of RA.

Abstract
Hepatitis C is both a cause and a complication of chronic renal disease. Chronic infection with hepatitis C virus (HCV) can lead to the immune complex syndromes of cryoglobulinemia and membranoproliferative glomerulonephritis (MPGN). The pathogenetic mechanisms for these conditions have not been defined, although they are clearly caused by the chronic viral infection. Management of HCV-related cryoglobulinemia and MPGN is difficult; antiviral therapy is effective in clearing HCV infection in a proportion of patients, but these conditions can be severe and resistant to antiviral therapy. Hepatitis C also is a complicating factor among patients with end-stage renal disease and renal transplants. The source of HCV infection in these patients can be nosocomial. Screening and careful attention to infection control precautions are mandatory for dialysis units to prevent the spread of hepatitis C. Prevention of spread is particularly important in these patients because HCV infection is associated with significant worsening of survival on dialysis therapy, as well as after kidney transplantation. Furthermore, therapy for hepatitis C is problematic, only partially effective, and associated with significant side effects in this population. There are significant needs in both basic and clinical research in the pathogenesis, natural history, prevention, and therapy for hepatitis C in patients with renal disease.

Abstract
UNLABELLED Vasculitis can range in severity from a self-limited single-organ disorder to a life-threatening disease with the prospect of multiple-organ failure. This condition presents many challenges to the physician, including classification and diagnosis, appropriate laboratory workup, treatment, and the need for careful follow-up. The physician must not only be able to recognize vasculitis but also be able to provide a specific diagnosis (if possible) as well as recognize and treat any underlying etiologic condition. Most diagnostic criteria are based on the size of vessel involvement, which often correlates with specific dermatologic findings. This may allow the dermatologist to provide an initial diagnosis and direct the medical evaluation. This article reviews the classification and diagnosis of cutaneous vasculitic syndromes and current treatment options; it also presents a comprehensive approach to diagnosing and treating the patient with suspected cutaneous vasculitis. (J Am Acad Dermatol 2003;48:311-40.) LEARNING OBJECTIVE At the completion of this learning activity, participants should be familiar with the classification and clinical features of the various forms of cutaneous vasculitis. They should also have a rational approach to diagnosing and treating a patient with vasculitis.

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
Monoclonal antibody and recombinant DNA technologies have led to the development of biologic therapies capable of directly targeting selected components of the immune response. With the steady expansion of knowledge regarding the mechanisms of vascular inflammation, the safety and efficacy of biologic agents in the vasculitic diseases are being increasingly investigated. By targeting specific effector mechanisms involved in the pathogenesis of vasculitis, these agents may provide a less toxic means of inducing remission and lessening relapse. However, the study of biologic therapies in the vasculitides must be approached with caution, as unanticipated effects on disease activity and disease-specific toxicities can occur. Studies to examine these agents must recognize the potential for active vasculitis to be organ- or life-threatening as well as the current existence of effective therapies. In the research setting, investigation of biologic agents in the treatment of vasculitic diseases may also provide important insights into pathogenesis of these syndromes.

Abstract
OBJECTIVE To assess the prevalence of TT virus (TMV) infection in a series of patients with chronic hepatitis C virus (HCV) infection, with or without benign (mixed cryoglobulinemia) or malignant (B-cell non-Hodgkin lymphoma (B-NHL)) lymphoproliferative disease. METHODS Sixty-six HCV patients were studied, including patients with mixed cryoglobulinemia (n=30), B-NHL (n=15), and no mixed cryoglobulinemia or B-NHL (n=21). All HCV patients had increased transaminase levels and were HCV RNA positive. Patients were considered to have mixed cryoglobulinemia if two successive determinations of their serum cryoglobulin level were above 0.05 g/L. Mixed cryoglobulinemia-negative patients never had mixed cryoglobulins in their serum on multiple determinations. Subjects without HCV infection included 79 patients with histologically proven B-NHL, and 50 healthy blood donors. Serum samples were analyzed for TTV DNA by nested polymerase chain reaction, with two couples of primers in different regions of the genome, in two independent laboratories. RESULTS In the group of HCV-positive patients, TTV DNA was found in one of 15 (6.7%) patients with B-NHL, and in nine of 51 (17.6%, P = 0.43) of those without B-NHL. Among HCV-positive patients without B-NHL, TTV DNA was more frequently found in those with type II mixed cryoglobulinemia vasculitis than in those without it (six of 16 (37.5%) versus two of 21 (9.5%), P = 0.05). In subjects without HCV infection, TTV DNA was present in 10 of 79 (12.7%) patients with B-NHL and in seven of 50 (14.0%, P = 0.82) blood donors. CONCLUSION In patients chronically infected with HCV, TTV co-infection: (1) is not associated with the presence of B-NHL; and (2) is more frequently found in patients presenting a type II mixed cryoglobulinemia vasculitis.

Abstract
Approximately 40% of patients with chronic hepatitis C virus (HCV) infection develop detectable serum cryoglobulins or cryoprecipitates (CP), although most do not show clinical or physical signs of syndromic cryoglobulinemia. Although association of HCV with the extrahepatic complications of cryoglobulinemia is widely recognized, the relationship of cryoglobulinemia with liver disease is unclear. We wished to study the relationship between CP and cirrhosis and to determine whether the development of CP is a true covariate for progressive liver disease or a confounding variable that impacts cirrhosis because of patient age, duration of disease, or differences in gender. We undertook a meta-analysis of 19 studies published between 1994 and 2001. The incidence of cirrhosis was compared in patients with and without CP after logistic regression adjustments for accepted risk factors for progressive liver disease, including age, gender, and estimated duration of disease (EDD). A total of 2,323 patients with chronic hepatitis C were identified, with 1,022 (44%) having detectable CP. Cirrhosis was present in 40% of patients with CP but only 17% of patients without CP (total Chi;(2) = 141.69, P <.001). After adjusting for age, gender, and estimated duration of disease by logistic regression, the combined odds ratio for incidence of cirrhosis in patients CP positive versus CP negative was 4.87, (95% CI: 3.32, 7.15), indicating a highly significant association between cirrhosis and cryoglobulinemia. In conclusion, cryoglobulins may be a useful prognostic indicator for increased risk of cirrhosis with chronic hepatitis C.

Abstract
Hepatitis C is an important and common cause of chronic hepatitis and cirrhosis. Cutaneous manifestations are often the first signs of infection. Dermatologists must be aware of these manifestations, because early diagnosis is the best treatment. HCV Ab by ELISA should be ordered in patients with LCV-urticarial vasculitis, cryoglobulinemia, lichen planus, Sjögren's syndrome, unexplained pruritus, PCT, PAN, chronic urticaria, patients starting methotrexate, unexplained pruritus, and any patient initiating therapy with a potentially hepatotoxic drug.

Abstract
Viral hepatitis is a common disease with significant morbidity and mortality that is found throughout the world. It is a known cause of acute and chronic liver disease. Because the disease can be asymptomatic in its acute stages, the diagnosis is often missed. This article reviews the extrahepatic manifestations of the disease, in particular the visible cutaneous lesions, which offer clues to the diagnosis of viral hepatitis. Familiarity with the most common skin lesions associated with each type of hepatitis virus will be useful in identifying previously undiagnosed individuals. This article serves as a review of the most widely published associations between skin diseases and specific subtypes of viral hepatitis.

Abstract
Cryoglobulins are immunogloblulins that persist in the serum, precipitate with cold temperature, and resolubilize when rewarmed. Mixed cryoglobulins, composed of different immunoglobulins, with a monoclonal component in type II and only polyclonal immunoglobulins in type III, are associated with connective tissue, malignant hematologic, or obvious infectious diseases. The syndrome of mixed cryoglobulinemia represents the consequence of an immune complex-type vasculitis. It is characterized by the clinical triad of purpura, arthralgia, and asthenia, and may involve numerous organs, particularly the peripheral nervous system and the kidneys. Mixed cryoglobulinemia frequently is associated with clinical and biologic evidence of liver disease. It seems fairly clear that mixed cryoglobulinemia is often a manifestation of underlying chronic active or persistent hepatitis. In the last 10 years, many studies have demonstrated that infection with hepatitis C virus is involved in the pathogenesis of most mixed cryoglobulinemia vasculitis. This review analyzes the main published data of hepatitis C virus-mixed cryoglobulinemia, the role of liver alterations, the predictive factors associated with mixed cryoglobulin production in hepatitis C virus patients and whether its character is symptomatic, and the different types of vasculitis associated with hepatitis C virus chronic infection and their treatments.

Abstract
Background: Essential mixed cryoglobulinemia (EMC) is a systemic disease frequently associated with chronic viral hepatitis. This study was conducted in order to assess the prevalence of EMC in patients with hepatitis B virus (HBV) or hepatitis C virus (HCV) infections. We also evaluated the possible associations of EMC with (1) the clinical, virological, and histological status of liver disease; (2) the presence of EMC-related symptoms; and (3) the response rate to interferon-alpha (IFN-alpha) treatment, in an attempt to address whether EMC is a major problem in hepatitis patients. Methodology: A total of 154 consecutive patients (104 with HBV and 50 with HCV infection) were investigated for the presence of rheumatoid factor (RF), cryoglobulins, and EMC-related manifestations. Sixty-two HBV patients were chronic carriers of hepatitis B surface antigen, 29 had chronic hepatitis B, and 13 HBV cirrhosis. Thirty-five HCV patients had chronic hepatitis C and 15 HCV cirrhosis. HCV genotyping was performed in 44 patients. Results: The prevalence of cryoglobulins was significantly higher (P<0.001) in HCV patients (46%) than in HBV patients (13.4%). EMC was associated with a high frequency of RF detection, older age, and longer duration of viral diseases. Weakness or malaise, arthralgias, and purpura were significantly more frequent in cryoglobulin-positive patients. These manifestations, however, were mild in most of the patients. The EMC-related symptoms were significantly associated with the presence of HCV infection, increased levels of cryoglobulins, and RF detection (P<0.01, P<0.05, and P<0.000005, respectively). Worse liver histology was unrelated to a higher prevalence or increased levels of cryoglobulins in both HBV and HCV infection. There was no relationship between EMC and a specific HCV genotype. IFN-alpha therapy led to the disappearance of cryoglobulins and EMC-related manifestations in most cases. The response rate to IFN-alpha was similar in both groups of patients (with and without EMC). Conclusions: A higher prevalence of EMC was observed in HCV patients than in HBV patients. However, this finding was unrelated to overt clinical manifestations of EMC, a specific HCV genotype, or worse liver histology. The latter suggests that EMC does not contribute to liver injury and vice versa, that EMC pathogenesis is rather unrelated to the degree of liver injury. From a clinical point of view, testing for cryoglobulins seems reasonable only for HCV patients with EMC-related manifestations, since this may have therapeutic consequences. RF detection could be used primarily as a surrogate marker for the existence of cryoglobulins.

Abstract
The efficacy of long-term interferon therapy for chronic hepatitis C infection with symptomatic mixed cryoglobulinemia has not clearly been defined. We describe a patient with chronic hepatitis C, symptomatic mixed cryoglobulinemia (cutaneous vasculitis), and membranoproliferative glomerulonephritis (MPGN) who responded clinically, biochemically, and virologically to a 1-year course of interferon therapy. Interferon side effects were minimal. Relapse occurred when interferon was discontinued, and suppressive maintenance interferon therapy was required for clinical, biochemical, and virologic remission. During the 5th year of maintenance therapy, she developed potential side effects that necessitated discontinuation of interferon treatment. After treatment stoppage, a clinical, biochemical, and virologic remission was maintained for more than 1 year. However, the potential side effects, which included eye irritation, arthralgias, myalgias, fatigue, insomnia, memory loss, and depression, persisted. Ophthalmologic, rheumatologic, and neurologic evaluations were nondiagnostic. Psychometric testing revealed dementia and mood disorder. Because the disabling symptoms persisted after 9 months, a health-related quality of life assessment was carried out with the SF-36 survey. Compared with healthy individuals and patients with chronic hepatitis C, our case had a lower health-related quality of life assessment on six out of seven scales and on four out of seven scales of the SF-36 survey, respectively. This case report indicates that long-term maintenance interferon therapy was effective in the treatment of symptomatic mixed cryoglobulinemia and its renal complications and resulted in a clinical, biochemical, and virologic sustained response. It is postulated that the side effects of long-term interferon therapy in this setting may be problematic.

Abstract
BACKGROUND/AIMS The association between mixed cryoglobulinaemia, cryoglobulinaemic glomerulonephritis, and chronic hepatitis C virus infection has recently been described. The renal disease had usually been treated with immunosuppressive therapy, but, given the presence of viral infection, this therapy is no longer recommended. In this study, we compare steroid vs interferon therapy in a group of patients affected by hepatitis C virus-positive cryoglobulinaemic glomerulonephritis in the stationary phase. PATIENTS/METHODS The diagnosis of cryoglobulinaemic glomerulonephritis was made bearing in mind standard criteria. Patients were randomly assigned to 2 groups receiving oral prednisone 0.2 mg/kg/die for 6 months (6 patients, group A) or lymphoblastoid interferon 3 MU, three times a week for 6 months [7 patients, group B). Hepatitis C virus-RNA was determined by reverse transcription-polymerase chain reaction and hepatitis C virus genotype according to Okamoto. Hepatitis C virus-RNA quantitation was performed by competitive polymerase chain reaction. RESULTS; The 2 groups were comparable in terms of age and severity of kidney failure. All genotypes of hepatitis C virus were found with a prevalence of Type 1b. In group A, 4 patients showed a partial response; in group B, 1 patient achieved complete remission, 4 a partial response, 2 patients in both groups showed no response. At the end of the treatment, all patients in both groups relapsed. Only 1 patient in group B became hepatitis C virus-RNA negative, and recovered from cryoglobulinaemic glomerulonephritis. CONCLUSIONS Interferon seems to be an effective drug in the treatment of cryoglobulinaemic glomerulonephritis, but dosage and length of treatment still need to be addressed by large multicentre studies.
