Abstract
Immunoglobulins that reversibly precipitate at temperatures below 37 °C are called cryoglobulins (CGs). Cryoglobulinemia often manifests as cryoglobulinemic vasculitis (CV), whose symptoms range in severity from purpuric eruptions to life-threatening features. The majority of CV patients are infected with hepatitis C virus (HCV), whereas lymphoproliferative disorders or connective tissue diseases (CTD) are commonly diagnosed among patients with CV of non-infectious origin. In the absence of detectable associated disease, cryoglobulinemia is classified as "essential" (EMC). All HCV-positive CV patients should be given direct-acting antiviral agents (DAAs) that are consistently able to induce a sustained virologic response (SVR). Glucocorticoids (GCs) can mitigate CV-associated vasculitis, but they have no role as maintenance therapy. Cyclophosphamide restrains the hyperactive phase(s) of the disease and the post-apheresis rebound of newly synthesized CGs. Its use has been largely replaced by rituximab (RTX) in patients unresponsive to DAAs, patients progressing to B-cell non-Hodgkin lymphoma (B-NHL) and patients in whom CV persists or reappears after clearance of HCV. Therapeutic apheresis is an emergency treatment for CV patients with hyperviscosity syndrome. HCV-positive CV patients are at an increased risk of developing NHL, but the achievement of SVR can effectively prevent HCV-related NHL or induce the remission of an already established lymphoma, even without chemotherapy. The treatment of patients with IgM or IgG monoclonal cryoglobulins and an underlying immunoproliferative disorder is based on the regimens adopted for patients with the same B-cell malignancies but without circulating CGs. For patients with CTD, GCs plus alkylating agents or RTX are similarly effective as first-line therapy and in the relapse/refractory setting. In patients with EMC, treatment should consist of GCs plus RTX, with the dose of GCs tapered as soon as possible to reduce the risk of infectious complications.

Abstract
Biologic therapies targeting B-cells are emerging as an effective strategy to treat a variety of immune-mediated diseases. One of the most studied B-cell-targeted therapies is rituximab, an anti-CD20 monoclonal antibody that exemplifies B-cell depletion therapy and has served as the prototype for other anti-CD20 monoclonal antibodies and the development of biosimilars. While there are multiple studies on the use of rituximab in dermatology, a comprehensive review of rituximab therapy in autoimmune skin conditions is lacking. In this literature review, we summarize indications, treatment efficacy, and safety of rituximab among common autoimmune diseases of the skin: pemphigus vulgaris, cutaneous lupus erythematous, dermatomyositis, systemic sclerosis, thyroid dermopathy, autoimmune pemphigoid diseases, and cutaneous vasculitis diseases. Existing data on rituximab support the approach of rituximab, biosimilars, and newer B-cell-targeting therapies in immune-mediated cutaneous diseases. Overall, rituximab, which targets CD20, provides an effective alternative or concomitant option to traditional immunosuppressants in the management of various autoimmune diseases of the skin. Further studies are necessary to expand the understanding and possible utility of B-cell-targeted therapies among autoimmune skin diseases.

Abstract
Background The management of nonviral cryoglobulinemic vasculitis (CV) has not been established yet. Randomized control trials are challenging to perform because of the rarity of the disease. The most promising biological therapy is rituximab (RTX), an anti-CD 20 monoclonal antibody. The aim of the study was to assess rituximab treatment's safety and effectiveness in patients with severe noninfectious cryoglobulinemic vasculitis. Materials and Methods We retrospectively reviewed 8 courses of RTX treatment in three patients with severe noninfectious CV. In 2 patients, the indication for the start of RTX therapy was the relapse of the disease despite the maintenance treatment, for the third patient, it was the first-line therapy. Results Clinical, renal, and immunologic efficacy was observed in all evaluable RTX courses. We found a significant decrease of cryoglobulins in the 3-rd month from RTX treatment. However, 5 clinical relapses occurred and two patients experienced severe adverse events (SAEs) after RTX therapy. Patients with SAEs were relatively older and had a longer duration of disease. Lower levels of hemoglobin, C3 component of complement and eGFR as well as higher rheumatoid factor (RF) concentration were observed before RTX treatments complicated with SAEs. Conclusion Data from our observation show the efficacy of rituximab in the refractory, nonviral cryoglobulinemic vasculitis with a severe course of the disease. However, the therapy is associated with the risk of SAEs, especially in elderly patients with kidney failure and significant immunologic alterations.

Abstract
Sustained virological response (SVR) obtained with interferon (IFN) or with direct-acting antivirals (DAAs) is commonly followed by response of hepatitis C virus (HCV)-associated mixed cryoglobulinemia vasculitis (MCV), but relapse of MCV despite SVR has been reported in several patients after DAAs and rarely after IFN. Since relapses could have been overlooked in studies with IFN, we retrospectively compared the outcomes of MCV in SVR patients treated with DAAs (n = 70) or IFN (n = 39) followed-up, respectively, for 30.5 (range 11-51) or 48 months. Groups were comparable for demographics and clinics and response rates of MCV were similar (92% and 86%); however, DAA-treated patients less efficiently reduced cryoglobulins (P = .006) and circulating B-cell clones (P = .004), and had more frequently relapses of MCV (18% vs 3%, P = .028) and need for rituximab therapy (P = .01). Although largely inferior on an intention-to-treat basis, IFN may be superior to DAAs on clinico-immunological outcomes possibly owing to its antiproliferative activity.

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
INTRODUCTION Hepatitis C virus (HCV) infection affects about 170 million people worldwide. HCV is responsible for both hepatitis and extra-hepatic manifestations. Chronic infection has been shown to develop in about 70% of cases, and it can progress to cirrhosis or hepatocellular carcinoma. Ten percent of HCV patients may develop extra-hepatic manifestations, including mixed cryoglobulinemia (MC) and non-Hodgkin lymphomas (NHL). Cryoglobulinemic vasculitis (CV) varies, ranging from mild-moderate clinical symptoms (purpura on the legs, asthenia and arthralgias) and chronic hepatitis to severe symptoms (ulcers on the legs, peripheral neuropathy, glomerulonephritis, low-grade NHL to life threatening complications (rapid progressive glomerulonephritis, gastrointestinal vasculitis, acute hyper-viscosity). EVIDENCE ACQUISITION CV is associated with significant morbidity and mortality. Some studies have shown kidney involvement, cirrhosis, central nervous system involvement, and heart involvement as unfavorable prognostic factors. Many studies have demonstrated that, after antiviral therapy, CV can disappear along with HCV. After the introduction of the new direct antiviral agents (DAAs), the combination of pegylated interferon and ribavirin has been abandoned. EVIDENCE SYNTHESIS Several studies on new DAAs have reported remarkable 90% to 100% HCV eradication rates, regardless of genotype. Treatment with DAAs has comparable efficacy on viral eradication in CV patients but definite clinical improvements of vasculitis can be observed only in half the patients. CONCLUSIONS In patients with mild to moderate CV disease, DAAs therapy should be used as first line approach. In patients with severe vasculitis, DAAs therapy and a second-line treatment with RTX with or without aphaeresis are a required.

Abstract
PURPOSE OF REVIEW The present review focuses on the new therapeutic opportunities offered by the combination of biological drugs, mainly Rituximab, with direct-acting antiviral agents (DAAs). RECENT FINDINGS Hepatitis C virus (HCV) is known to be the etiologic agent in the majority of patients with mixed cryoglobulinemia syndrome. Clinical research has been focused on antiviral drugs and, more recently, on the new, highly potent DAAs. New DAAs assure sustained virologic response (SVR) rates greater than 90% with relief of mild-to-moderate symptoms. SUMMARY Mixed cryoglobulinemia may present with multiorgan vasculitis involving kidneys, joints, skin, and peripheral nerves. Data on DAAs efficacy in HCV-associated cryoglobulinemic vasculitis are disappointing possibly because of the inability of these drugs to suppress the immune-mediated process once it has been triggered. Immunosuppression has often been employed in the past as a first-line therapy in cryoglobulinemic vasculitis despite the potential risk of the infection exacerbation. However, more manageable Rituximab-based therapeutic approaches have been more recently used without increase of viral load. Rituximab substantially changed the outcome of HCV-associated cryoglobulinemic vasculitis by providing long-term remission. A combination schedule of DAAs and Rituximab may result in eradication of both cryoglobulinemic vasculitis and HCV infection.

Abstract
Cryoglobulins are circulating immunoglobulins that reversibly precipitate at temperatures below 37 °C. Type-II cryoglobulins consist of monoclonal IgM/polyclonal IgG immune complexes (ICs), whereas in type-III cryoglobulins both IgM and IgG are polyclonal. The clinical condition resulting from the presence of cryoglobulins in the blood is called mixed cryoglobulinemia (MC), which can be asymptomatic or manifest as cryoglobulinemic vasculitis (CV). Type-I cryoglobulins, consisting of a single monoclonal isotype, are detected in patients with lymphoproliferative disorders. It is now established that > 90% of MCs are associated with HCV infection. Clinically, the spectrum of symptoms may range in severity from occasional purpuric eruptions to life-threatening features. In addition to the development of liver cirrhosis and hepatocellular carcinoma, the possible progression of HCV-positive CV patients to B-cell non-Hodgkin lymphoma (B-NHL) has been reported. The pathogenetic role played by HCV infection in the onset of B-NHL is suggested by regression of the latter following the achievement of a sustained virologic response (SVR). For several years, interferon-α alone or combined with ribavirin has been the standard of care. However, the rates of clinical, biochemical, and virologic responses have been low, and the occurrence of relapse frequent. The addition of rituximab has resulted in a higher rate of responses. With the advent of direct-acting antiviral agents, SVR has been achieved in ~ 95% of CV patients. However, in a minority of patients, despite SVR, CV may persist or reappear over variable lengths of time from the completion of therapy. The eventual appearance of B-NHL is also possible.

Abstract
Cryoglobulinaemia refers to the serum presence of cryoglobulins, which are defined as immunoglobulins that precipitate at temperatures <37 °C. Type I cryoglobulinaemia consists of only one isotype or subclass of monoclonal immunoglobulin, whereas type II and type III are classified as mixed cryoglobulinaemia because they include immunoglobulin G (IgG) and IgM. Many lymphoproliferative, infectious and autoimmune disorders have been associated with mixed cryoglobulinaemia; however, hepatitis C virus (HCV) is the aetiologic agent in most patients. The underlying mechanism of the disorder is B cell lymphoproliferation and autoantibody production. Mixed cryoglobulinaemia can cause systemic vasculitis, with manifestations ranging from purpura, arthralgia and weakness to more serious lesions with skin ulcers, neurological and renal involvement. This Primer focuses on mixed cryoglobulinaemia, which has a variable course and a prognosis that is primarily influenced by vasculitis-associated multiorgan damage. In addition, the underlying associated disease in itself may cause considerable mortality and morbidity. Treatment of cryoglobulinaemic vasculitis should be modulated according to the underlying associated disease and the severity of organ involvement and relies on antiviral treatment (for HCV infection), immunosuppression and immunotherapy, particularly anti-CD20 B cell depletion therapies.

Abstract
Mixed cryoglobulinemia syndrome (MC) is a systemic vasculitis involving kidneys, joints, skin, and peripheral nerves. While many autoimmune, lymphoproliferative, and neoplastic disorders have been associated with this disorder, hepatitis C virus (HCV) is known to be the etiologic agent in the majority of patients. Therefore, clinical research has focused on anti-viral drugs and, more recently, on the new, highly potent Direct-acting Antiviral Agents (DAAs). These drugs assure sustained virologic response (SVR) rates >90%. Nevertheless, data on their efficacy in patients with HCV-associated cryoglobulinemic vasculitis are disappointing, possibly due to the inability of the drugs to suppress the immune-mediated process once it has been triggered.Despite the potential risk of exacerbation of the infection, immunosuppression has traditionally been regarded as the first-line intervention in cryoglobulinemic vasculitis, especially if renal involvement is severe. Biologic agents have raised hopes for more manageable therapeutic approaches, and Rituximab (RTX), an anti CD20 monoclonal antibody, is the most widely used biologic drug. It has proved to be safer than conventional immunosuppressants, thus substantially changing the natural history of HCV-associated cryoglobulinemic vasculitis by providing long-term remission, especially with intensive regimens.The present review focuses on the new therapeutic opportunities offered by the combination of biological drugs, mainly Rituximab, with DAAs.

Abstract
Hepatitis C Virus (HCV)-related Mixed Cryoglobulinemia (MC) is a unique condition with complex pathogenesis that involves HCV antigen-driven B-lymphocyte clonal proliferation and mutagenesis. Clinical spectrum of MC ranges from asymptomatic state to clinically-apparent vasculitis involving multiple organs. In the era of Direct-Acting Antiviral (DAA) therapy, patients with HCV-related MC achieve high rates of viral clearance that is commonly accompanied by an improvement in clinical symptoms as well as immunological profiles. Rituximab, either alone or in combination with DAA, has also been shown to be effective. Nevertheless, there have been limited and somewhat conflicting data, particularly over the long-term, regarding the rate and degree of clinical response of MC following DAA therapy. It appears that we have come quite a long way in the last decade with this condition. As with non-MC related HCV, undoubtedly long term outcome data will be forthcoming over the next few years. As we move forward successful therapy of HCV is not likely to be a challenge in contrast to access to therapy.

Abstract
BACKGROUND The conventional frontline therapy for fit patients with chronic lymphocytic leukaemia (CLL) is fludarabine, cyclophosphamide and rituximab (FCR). Rituximab (Mabthera®, Roche Products Ltd) targets the CD20 antigen, which is expressed at low levels in CLL. The standard dose of rituximab in CLL (375 mg/m2 in cycle 1 and 500 mg/m2 in cycles 2-6) was selected based on toxicity data only. Small doses of rituximab (as low as 20 mg) have biological activity in CLL, with an immediate reduction in circulating CLL cells and down-regulation of CD20. Phase II trials had suggested improved efficacy with the addition of mitoxantrone to FCR. The key assumption for the Attenuated dose Rituximab with ChemoTherapy In CLL (ARCTIC) trial was that the addition of mitoxantrone to fludarabine, cyclophosphamide and low-dose rituximab would be more effective than conventional FCR. OBJECTIVES To assess whether fludarabine, cyclophosphamide, mitoxantrone and low-dose rituximab (FCM-miniR) (100 mg of rituximab per cycle) was non-inferior to FCR in frontline CLL. Complete response (CR) rate was the primary end point, with the secondary end points being progression-free survival (PFS), overall survival (OS), overall response rate, eradication of minimal residual disease (MRD), safety and cost-effectiveness. DESIGN ARCTIC was a UK multicentre, randomised, controlled, open, Phase IIB non-inferiority trial in previously untreated CLL. A total of 206 patients with previously untreated CLL who required treatment, according to the International Workshop on Chronic Lymphocytic Leukaemia criteria, were to be randomised to FCR or FCM-miniR. There was an independent Data Monitoring and Ethics Committee (DMEC) with a pre-planned interim efficacy assessment on 103 participants. RESULTS The DMEC's interim analysis led to early trial closure. Although the response rates in both arms were higher than anticipated, FCM-miniR had a lower CR rate than FCR. This was partly attributable to the higher toxicity associated with mitoxantrone. A total of 100 participants completed FCR, 79 completed FCM-miniR and 21 commenced FCM-miniR but switched to FCR following DMEC recommendations. The CR rate for participants receiving FCR was 76%, compared with 55% for FCM-miniR (adjusted odds ratio 0.37; 95% confidence interval 0.19 to 0.73). Key secondary end points also showed that FCR was superior, with more participants achieving MRD negativity (57% for FCR vs. 46% for FCM-miniR). More participants experienced a serious adverse reaction with FCM-miniR compared with FCR (50% vs. 41%). At a median of 37.3 months' follow-up, the PFS and OS rates are good compared with previous studies, with no significant difference between the treatment arms. The economic analysis indicates that because FCM-miniR is less effective than FCR, FCM-miniR is not expected to be cost-effective over a lifetime horizon, producing a mean cost-saving of -£7723, a quality-adjusted life-year loss of -0.73 and a resulting incremental net monetary loss of -£6780. CONCLUSIONS FCM-miniR is less well tolerated, with poorer response rates, than FCR, partly owing to the additional toxicity associated with mitoxantrone. In view of this, FCM-miniR will not be taken forward into a larger definitive Phase III trial. The trial demonstrated that oral FCR yields extremely high response rates compared with historical series with intravenous chemotherapy. FUTURE WORK We shall compare the results of ARCTIC with those of the ADMIRE (Does the ADdition of Mitoxantrone Improve Response to FCR chemotherapy in patients with CLL?) trial, which compared FCR with FCM-R to assess the efficacy of low- versus standard-dose rituximab, allowing for the toxicity associated with mitoxantrone.

Abstract
Rituximab (RTX) is established for the treatment of rheumatoid arthritis. This systematic review of the literature since 2006 summarizes evidence for the use of RTX in the treatment of additional rheumatological diseases: antineutrophil cytoplasmic autoantibody-associated vasculitis (AAV), hepatitis C virus-related cryoglobulinemic vasculitis, Henoch-Schönlein purpura, ankylosing spondylitis, and Raynaud's phenomenon. Data from randomized controlled trials are available only for AAV, confirming efficacy for remission induction, including in disease resistant to conventional treatment, and maintenance of remission. Further studies are required to confirm optimal maintenance regimens in AAV, important questions needing to be addressed including protocol administration versus treatment in response to clinical relapse and the importance of maintaining B-cell depletion. Sufficient data are available in other diseases to suggest RTX to be useful and that randomized controlled trials should be conducted.

Abstract
INTRODUCTION Treatment of systemic vasculitis is based on glucocorticoids (GC) in association with immunosuppressive therapy. There are still unmet needs, including earlier onset of response, more targeted therapies, reduction of relapse-risk and decrease of long-term GC and classic immunosuppressants toxicities. Areas covered: In this review, we discuss investigational drugs in early phase clinical trials for induction of remission in vasculitis. We focus on ANCA-associated vasculitis, Behçet's disease, giant cell arteritis, Takayasu arteritis, and cryoglobulinemic vasculitis. We performed a comprehensive review of articles published on pubmed and a review of clinical trials registered online ( https://clinicaltrials.gov ) for each vasculitis. Expert opinion: Recent progress in the pathogenesis identifies new therapeutic targets. Some of these therapies are promising in GC sparing effects, in reducing relapse rate, and for their safety profile. These results need to be confirmed in large-scale phase III studies.

Abstract
INTRODUCTION The hepatitis C virus (HCV) is recognized as one of the hepatic viruses most often associated with extrahepatic manifestations (EHMs). It is currently accepted that cryoglobulinemic vasculitis (CV) is the key autoimmune extrahepatic disease associated with HCV infection. Therapeutic approaches have mainly been based on the use of old antiviral interferon (IFN)-based regimens and immunosuppressive therapies, often with an inadequate balance between therapeutic benefits and excess side effects. Areas covered: Therapeutic management of HCV patients with EHMs, including both non-autoimmune (cardiovascular, hematological, general features) and autoimmune complications (organ-specific and systemic autoimmune diseases). Therapies included antiviral (IFN, ribavirin, direct-acting antivirals - DAAs-) and non-antiviral (immunosuppressive agents, rituximab, plasma exchanges) options. The review analyses the current evidence for proposing a treat-to-target (T2T) approach for HCV-related autoimmune EHMs based on an organ-by-organ strategy. Expert commentary: Eradication of HCV must be considered the key T2T in the therapeutic approach to HCV-related EHMs, as there has been a disruptive change due to the appearance of direct-acting antivirals (DAAs) as game-changers in HCV therapy, with an efficacy reaching nearly 100%. In this scenario, the central role played until now by IFN and ribavirin is not currently supported and they will not be used in the future.

Abstract
This study aims to evaluate the efficacy and safety of repeated treatments with low-dose rituximab for relapsing mixed cryoglobulinemia vasculitis. Thirty-seven patients with mixed cryoglobulinemia vasculitis refractory to standard of care treatment, 34 of which were HCV-positive, were treated with rituximab at the reduced dosage of 250 mg/m2 given twice 1 week apart per cycle. Thirty patients (81%) achieved a clinical response; 5 of them remain in remission, 3 were lost to follow-up or died, and 22 relapsed after a mean of 15.7 months. Eleven relapsers were retreated with one (6 patients), 2 (3 patients), or 3 (2 patients) additional rituximab cycles given at each relapse. Clinical and laboratory efficacy and side effects of long-term treatment were evaluated. Clinical response to retreatment was 91% (10/11) at the first relapse, 80% (4/5) at the second relapse, and 100% (2/2) at the third relapse. The mean (±SD) time to relapse was 17.1 ± 14.1 months in 30 patients who were treated with only one cycle (from first cycle to the first relapse) and 45.7 ± 30.6 months (from first cycle to the last observed relapse) in 11 patients treated with 2 or more cycles (p = 0.0037). Severe adverse reactions occurred in 3 patients, in 2 of whom at the first cycle. Our results suggest that repeated treatment of relapsing mixed cryoglobulinemia with a low-dose rituximab regimen is efficacious, safe, and cost-effective for the long-term management of this disorder.

Abstract
Cryoglobulinemia is a distinct entity characterized by the presence of cryoglobulins in the serum. Cryoglobulins differ in their composition, which has an impact on the clinical presentation and the underlying disease that triggers cryoglobulin formation. Cryoglobulinemia is categorized into two main subgroups: type I, which is seen exclusively in clonal hematologic diseases, and type II/III, which is called mixed cryoglobulinemia and is seen in hepatitis C virus infection and systemic diseases such as B-cell lineage hematologic malignancies and connective tissue disorders. Clinical presentation is broad and varies between types but includes arthralgia, purpura, skin ulcers, glomerulonephritis, and peripheral neuropathy. Life-threatening manifestations can develop in a small proportion of patients. A full evaluation for the underlying cause is required, because each type requires a different kind of treatment, which should be tailored on the basis of disease severity, underlying disease, and prior therapies. Relapses can be frequent and can result in significant morbidity and cumulative organ impairment. We explore the spectrum of this heterogeneous disease by discussing the disease characteristics of 5 different patients.

Abstract
BACKGROUND In 2005 the Italian Medicines Agency (AIFA) started a program on independent research on drugs, with the aim to promote clinical research in areas of limited commercial interest. For 3 years (2005-2007) an area of the program was reserved to studies in the field of rare diseases. There is a concern that public funding of research may be wasted. We investigated the outcome of the program. METHODS We conducted a cohort study on the projects that were funded by the AIFA in the area of rare diseases. The outcomes were the proportion of published studies, time to publication, impact factor of the publishing journals and relevance for clinical practice. We retrieved published articles through a literature search in peer reviewed biomedical journals indexed by Pubmed. We used the Kaplan-Meier method to estimate the cumulative probability of publication by time from project starting to publication. RESULTS During the period 2005-2007, 62 projects were funded in the area of rare diseases. Most of the studies (n 39; 63%) had a randomized design and in 22 (35%) the control group received an active treatment. For 39 studies (63%) we retrieved a publication in a peer reviewed journal. The median time to publication was 74 months and, at the maximum period of follow up (109 months), the cumulative probability of publication reached 77%. The median impact factor was 5.4 (range 1.4-52.4). Considering the clinical relevance, more than 30% of the published articles presented conclusive findings; an additional 10% of the studies reached potential breakthrough findings. CONCLUSIONS Even though it takes time to set up and conduct a funding program for independent research on drugs, the results are highly rewarding. Independent funding is crucial in supporting studies aimed at answering questions that are relevant for clinical practice despite the lack of sufficient commercial interest.

Abstract
OBJECTIVE To evaluate whether rituximab at a low dose of 250 mg/m(2) × 2 may be as effective as at higher dosages, most commonly 375 mg/m(2)×4, used in previous studies on the treatment of patients with refractory mixed cryoglobulinemia (MC) vasculitis associated with hepatitis C virus (HCV) infection. METHODS We conducted a phase 2, single-arm two-stage trial (EUDRACT n. 2008-000086-38) of low-dose rituximab in 52 patients with HCV-associated MC who were ineligible/intolerant or non-responder to antiviral therapy. The primary outcomes were response of vasculitis evaluated by the Birmingham Vasculitis Activity Score (BVAS) at months 3, 6 and 12, rate of relapses and time to relapse, and rate of adverse events. Our data were compared with those reported in 19 published studies selected among 291 reviewed in a literature search. RESULTS The cumulative response rate (complete and partial) at month 3 was 81% in our patients, and 86% in 208 patients from studies using high-dose rituximab. The relapse rate and median time to relapse were, respectively, 41% and 6 months in our study, and 32% and 7 months in high-dose studies. Treatment-related adverse events were 11.5% in our study and 19.9% in high-dose studies. None of these differences was statistically significant. CONCLUSION Rituximab at a low dosage of 250 mg/m(2) × 2 is as effective as at higher dosages for treating MC vasculitis. This low-dose regimen may improve the cost/benefit profile of rituximab therapy for MC.

Abstract
HCV chronic infection is characterized by possible development of both hepatic and extrahepatic manifestations. The infection by this both hepatotropic and lymphotropic virus is responsible for polyoligoclonal B-lymphocyte expansion, leading to several immune-mediated disorders. Mixed cryoglobulinemia syndrome that in some cases may evolve to frank B-cell non-Hodgkin's lymphoma is the prototype of HCV-driven autoimmune and lymphoproliferative disorders. The HCV oncogenic potential has been suggested by several clinicoepidemiological and laboratory studies; it includes hepatocellular carcinoma, B-cell non-Hodgkin's lymphoma and papillary thyroid cancer. The definition HCV syndrome refers to the complex of HCV-driven diseases; these latter are characterized by heterogeneous geographical distribution, suggesting a role of other important genetic and/or environmental cofactors. The natural history of HCV syndrome is the result of a multifactorial and multistep pathogenetic process, which may evolve from mild manifestations to systemic autoimmune disorders, and less frequently to malignant neoplasias. The present updated review analyzes the clinical and pathogenetic aspects of the main HCV-associated diseases.

Abstract
Cryoglobulinemia is a heterogeneous systemic autoimmune disease with a wide variety of causes, symptoms and outcomes, and different etiopathogenic pathways involved in the vasculitic organ damage. The discovery of the hepatitis C virus (HCV) in 1989 changed radically the focus of research of the so-called "essential" cryoglobulinemia. Cryoglobulins can be detected in 25-30% of patients with HCV, overwhelmingly representing mixed cryoglobulins. However, only 10-15% of patients present with cryoglobulinemic vasculitis, with a broad spectrum of symptoms including mild or life-threatening manifestations. Consequently, not all patients can be uniformly treated. The key therapeutic points in HCV+ patients with cryoglobulinemic vasculitis cover different aspects. The first is to treat the underlying cause of cryoglobulinemia whenever possible, hence the use of antiviral therapies must always be considered in these patients. An individualized diagnostic approach to assess the number of organs involved and the severity of organ involvement is also essential in the therapeutic planning. This complex clinical scenario leads to an equally complex therapeutic scenario. There are three main treatment strategies for HCV-associated cryoglobulinemic vasculitis: conventional immunosuppression, antiviral treatment and biological therapies. The most recent studies are suggesting a change from the classical therapeutic approach (monotherapeutic regimens) to combination/sequential regimens, including treatments targeting the virus and those directed against the induced autoimmune disease, with the aim of blocking the various etiopathogenic pathways involved.

Abstract
OBJECTIVE Obtaining a sustained virologic response (SVR) in patients with chronic hepatitis C virus (HCV) can decrease hepatic complications and be curative, however, extrahepatic manifestations including mixed cryoglobulinemia (MCN) may persist with interferon-based therapy. Our objective was to review our experience in treating patients with new oral antiviral agents and to assess common factors associated with MCN persistence despite SVR. METHODS We analyzed a case series of five patients with genotype one chronic HCV complicated by MCN who had persistence of cryoglobulins despite completion of triple therapy with oral antiviral agents (boceprivir, telaprivir or sofosbuvir). RESULTS Patients with cirrhosis appear to have a decreased ability to clear immune complexes. We observed that early viral response by week 8 of therapy and longer periods of undetectable virus on treatment correlated with eventual clearance of serum cryoglobulins in patients without cirrhosis. Two patients were treated with anti-B-cell agent rituximab prior to starting therapy for HCV; this did not lead to a more effective clearance of cryoglobulins. CONCLUSIONS We suggest that a longer treatment course than the standard 24 weeks with triple therapy could aid in the clearance of these immune complexes and cryoglobulins in cirrhotics. More studies to determine the ideal duration of treatment for chronic HCV and coincident MCN are needed, especially in light of the new all oral direct-acting antiviral regimens that are now recommended for HCV treatment.

Abstract
BACKGROUND Rituximab is a monoclonal antibody directed against B cells and is increasingly used to treat a variety of autoimmune conditions. Most published evidence reporting the successful use of rituximab in off-label indications has empirically used a high-dose regimen (either 375 mg/m(2) weekly for 4 weeks, or 1000 mg × 2), which is the approved course of treatment for lymphoma and rheumatoid arthritis patients. AIMS The aims of this report are to review the indications, outcomes and adverse events of low-dose (500 mg twice, given 1-2 weeks apart), off-label use of rituximab in our institutions, and to review the available evidence. METHODS We performed a retrospective audit of the off-label use of low-dose rituximab at two university teaching, tertiary referral hospitals, from mid-2008 until the end of 2011. RESULTS Off-label rituximab was given to 52 patients (53 indications) across a heterogeneous group of autoimmune conditions. Outcomes were known for 46 conditions (affecting 45 patients), and of these, complete responses were observed in 16 (35%) conditions and a further 19 (41%) had a partial response. There was no response to rituximab in 11 (24%) patients. There were eight significant adverse events, mostly related to infectious complications. CONCLUSION This case series suggests that low-dose courses of rituximab can be used off-label to treat several severe and/or refractory immunological disorders with a reasonable safety profile; however, further trials are required in many off-label indications.

Abstract
Mixed cryoglobulinaemia syndrome (MCS) is associated with a number of infectious, autoimmune and lymphoproliferative disorders, particularly chronic hepatitis C infection. Although circulating mixed cryoglobulins (cMCGs) are a frequent finding in HCV-infected patients, only a minority of them develop a frank MCS. The only available data concerning the prevalence of MCS, which is generally considered a rare disease, come from hospital records. The aim of this investigation was to estimate the prevalence of cMCGs and MCS in a population-based study. All of the adult residents in Origgio, a town of about seven thousand inhabitants in northern Italy, were mailed a validated questionnaire, and a randomly selected sample of respondents was invited to undergo a clinical examination and laboratory tests including the determination of cMCGs. The 1594 respondents to the questionnaire (54.3% women, 64.5% aged >49years) accounted for 26.4% of the total adult population. Forty-nine (3.1%) positively responded to at least two questions, including a disproportionately high number of people aged >70years (p=0.001). Of the 266 randomly selected subjects invited to undergo a clinical examination and laboratory tests, 147 accepted, 30 (20.4%) of whom had asymptomatic type III cMCGs and four MCS. The risk of cMCG positivity was independently associated with C4 levels of <16mg/dL (adjusted odds ratio [AOR] 4.40, 95% confidence interval [CI] 1.07-18.08; p=0.040) and HCV positivity (AOR 6.87, 95% CI 1.16-40.79; p=0.034). No co-morbidities known to be related to cMCG production could be detected in more than 50% of the positive cases. After including the other positive respondents who agreed to undergo a clinical examination, the number of diagnosed MCS increased to seven: five HCV-related, one HBV-related, and one essential MCS. In conclusion, MCS seems to be more frequent than expected for a 'rare' disease, and the unexpectedly high prevalence of cMCGs raises questions about the frequency with which they are triggered, the spectrum of diseases involved in triggering them, and their real role as disease indicators.

Abstract
BACKGROUND Hepatitis C virus (HCV) is associated with B-cell disorders, including mixed cryoglobulinemia (MC) and B-cell non-Hodgkin lymphoma (B-NHL). We hypothesized that combination of serum biomarkers could be used to identify B-NHL in HCV patients. METHODS We measured in 155 HCV infected patients, with and without MC and/or B-NHL, serum levels of eight markers previously described to be increased in patients with B-NHL, i.e. sCD22, sCD27, sIL-2Rα, sCD137, free-light chains of Ig (ratio κ/λ), heavy chains of Ig (ratio IgMκ/IgMλ), gammaglobulins and C4. We used a multiparametric analysis to determine a signature that identifies patients with overt B-NHL. RESULTS Serum levels were significantly different between patients without MC, patients with asymptomatic MC, patients with MC vasculitis and those with MC vasculitis and B-NHL for all biomarkers except for sCD137. Using multiparametric analysis, we identified a signature involving sCD27, sIL-2Rα, gammaglobulins and C4 levels associated with the presence of overt B-NHL in HCV-infected patients. This signature had a sensitivity of 100%, a specificity of 90%, and positive and negative predictive values of 97 and 100%, respectively for discriminating patients with overt B-NHL and those without B-NHL. CONCLUSION Our data indicate that serum biomarker signature allows identifying HCV-infected patients presenting with overt B-NHL.

Hepatitis C virus (HCV) is now well recognised as the main etiologic agent of mixed cryoglobulinaemia vasculitis (cryovas). New opportunities and problems in developing therapy have therefore emerged. Antiviral therapy with pegylated interferon-α and ribavirin (plus protease inhibitor in the case of HCV genotype 1 infection) should be considered as induction therapy for HCV-cryovas with mild to moderate disease severity and activity. An early virologic response to antiviral therapy is correlated with a complete clinical response of HCV-cryovas. In patients presenting with more severe disease (ie, worsening of renal function, mononeuritis multiplex, extensive skin disease including ulcers and distal necrosis), an immunosuppression induction phase is often necessary while awaiting the generally slow response to antiviral treatments. Combination therapy with rituximab plus an optimal antiviral agent is recommended, as it may target the downstream B cell arm of autoimmunity and the viral trigger. Careful monitoring for adverse effects is mandatory, since some manifestations of HCV-cryovas, such as peripheral neuropathy or skin ulcers, may worsen with interferon-based therapy. Clinicians should be aware of the possibility of malignant lymphoma when patients develop a relapse of cryovas without virological relapse. Room for other treatment strategies is very limited. Low-dose corticosteroids may help to control minor intermittent inflammatory signs such arthralgia but do not succeed in case of major organ involvement. Other immunosuppressants should be given only in case of refractory forms of HCV-cryovas, which are frequently associated with an underlying B cell lymphoma.

Abstract
The Therapeutic Antibodies and Infectious Diseases international congress was held in Tours, France on November 20−22, 2012. The first session was devoted to the development of antibodies directed against bacterial toxins or viruses that could be used in a potential bioterrorist threat situation. The second session dealt with the effector functions of anti-microbial antibodies, while the third was oriented toward anti-viral antibodies, with a special emphasis on antibodies directed against the human immunodeficiency and hepatitis C viruses. After a lecture by a speaker from the US Food and Drug Administration on antibody cocktails, the second day ended with a special session dedicated to discussions regarding the involvement of French biotechnology industries in the field. On the last day, the congress concluded with talks about current antibody treatments for infectious diseases, with a particular focus on their adverse events. Participants enjoyed this very stimulating and convivial meeting, which gathered scientists from various countries who had different scientific research interests.

Abstract
PURPOSE OF REVIEW Vasculitic neuropathy is a heterogeneous disorder that usually occurs in systemic diseases, but less commonly appears as nonsystemic vasculitic neuropathy (NSVN). This review is intended to highlight recent developments in the field of vasculitic neuropathies. RECENT FINDINGS A Peripheral Nerve Society guideline provides data-driven consensus recommendation on classification of vasculitic neuropathies and diagnosis/treatment of NSVN. NSVN is sometimes accompanied by subclinical inflammation of adjacent skin. Amyotrophic lateral sclerosis with sensory involvement can mimic NSVN. Systemic vasculitides with neuropathy include polyarteritis nodosa, microscopic polyangiitis (MPA), rheumatoid vasculitis, Churg-Strauss syndrome (CSS), and hepatitis C-related mixed cryoglobulinemic vasculitis (MCV). At autopsy, MPA affects limb nerves diffusely, with maximal damage in proximal/middle segments. CSS can be accompanied by antineutrophil cytoplasmic antibodies (ANCAs), but most patients with neuropathy lack ANCAs. Cryoglobulinemic neuropathies are usually caused by vasculitis, irrespective of phenotype. Two randomized trials revealed rituximab to be noninferior to cyclophosphamide for inducing remission in ANCA-associated vasculitis. Many reports also document efficacy of rituximab in MCV. SUMMARY Consensus guidelines on NSVN should be evaluated prospectively. MPA-associated vasculitic neuropathy results from vasculitic lesions distributed diffusely throughout peripheral extremity nerves. Rituximab is effective for ANCA-associated and cryoglobulinemic vasculitis with neuropathy.

Abstract
Hepatitis C virus (HCV) may instigate mixed cryoglobulinemia; the most significant accompanying kidney lesion is type I membranoproliferative glomerulonephritis, usually occurring in the context of type II mixed cryoglobulinemia. Additionally, recent data support a link between HCV infection and proteinuria in population-based studies, raising the possibility that kidney diseases associated with HCV may be more common than previously thought. A number of strategies have been used to treat HCV-related glomerulonephritis, including antiviral agents, immunosuppressive therapies such as corticosteroids and cytotoxic agents, and plasma exchange. Limited but encouraging data about the utility of antiviral treatment in the setting of HCV-associated glomerulonephritis exist, with one pooled analysis noting a sustained viral response of 42%, albeit with significant heterogeneity. Immunosuppressive therapy may be most useful for cryoglobulinemic kidney disease, with individualized approaches considered for the treatment of HCV-associated cryoglobulinemic glomerulonephritis based on the level of proteinuria and kidney failure. Of note, rituximab, a chimeric monoclonal antibody that blocks CD20 receptors on B cells, has been reported to be effective for the treatment of mixed cryoglobulinemia symptoms, including glomerulonephritis.

Abstract
Hepatitis C Virus (HCV) is a major health problem, infecting about 3 % of people worldwide and leading to liver as well as extrahepatic diseases. This justifies the definition of HCV infection as a systemic disease. Based on available data, the link between the virus and some of these extrahepatic disorders is certain, whereas for some others needs further confirmation. HCV-related lymphoproliferative disorders, ranging from benign, but pre-lymphomatous conditions, like mixed cryoglobulinemia, to frank lymphomas, represent the extrahepatic manifestations most closely related to HCV. The primary involvement of the liver and lymphatic system corresponds to the double viral tropism, being HCV able to infect both hepatic and lymphatic cells. Other HCV-associated disorders include renal, endocrine, dermatological, cardiovascular, rheumatologic and central nervous system diseases. On the whole, the HCV disease appears a very important, mainly hidden, public health problem leading to heavy direct and indirect costs. The possibility that HCV may be eradicated following antiviral therapy is important for both the therapeutic and preventive points of view, making the HCV disease an ideal model for pathogenetic studies.

Abstract
Patients with chronic hepatitis C virus (HCV) can develop systemic cryoglobulinemic vasculitis. Combination of pegylated-interferon α and ribavirin is the first-line treatment of this condition. However, in case of severe or life-threatening manifestations, absence of a virological response, or autonomized vasculitis, immunotherapy (alone or in addition to the antiviral regimen) is necessary. Rituximab is to date the only biologic with a sufficient level of evidence to support its use in this indication. Several studies have demonstrated that rituximab is highly effective when cryoglobulinaemic vasculitis is refractory to antiviral regimen, that association of rituximab with antiviral regimen may induce a better and faster clinical remission, and, recently, that rituximab is more efficient than traditional immunosuppressive treatments. Some issues with regard to the optimal dose of rituximab or its use as maintenance treatment remain unsolved. Interestingly, in balance with this anti-inflammatory strategy, a recent pilot study reported the significant expansion of circulating regulatory T lymphocytes with concomitant clinical improvement in patients with refractory HCV-induced cryoglobulinaemic vasculitis using low dose of subcutaneous interleukin-2. This paper provides an updated overview on the place of immunotherapy, especially biologics, in the management of HCV-induced cryoglobulinaemic vasculitis.

Abstract
Infections by the viruses responsible for hepatitis B, C and D are accompanied by a number of immunopathological manifestations. A link between infection and autoimmunity is particularly well documented for the hepatitis C virus. Immunopathological manifestations range from production of autoantibodies to overt autoimmune disease, including thyroiditis and autoimmune hepatitis, and to immune-complex-mediated disorders, including cryoglobulinaemia, glomerulonephritis and vasculitis. Several of these manifestations improve with successful antiviral treatment, directly incriminating the virus in their pathogenesis. Mechanisms considered responsible for hepatitis virus-related immunopathology, including molecular mimicry, impairment of regulatory T cells and activation of B lymphocytes, will be examined in this review.

Abstract
Hepatitis C virus (HCV) chronic infection is recognized as the major cause of mixed cryoglobulinemia (MC). Its persistence represents a continuous stimulus for host immune system with production of circulating immune complexes (ICs), one-third of them with cryoprecipitate property. Several factors contribute to the biological activities of ICs, many of which are not completely known. Among them, complement factors play a crucial role in the cold-insoluble ICs-mediated vasculitis, involving primarily small blood vessels in different tissues including skin, kidney, peripheral, and central nervous system. Liver represents the major target of HCV infection with inflammatory infiltrates, resembling secondary lymphoid follicles. Cytokine like CXCL13 contribute to B-cell homing in intraportal lymphoid aggregates, in which B-cell clonal selection may arise. B-cell clonal expansion starts as an antigen-driven event and expands towards indolent and malignant B-cell proliferation. Occurrence of intrahepatic B-cell clonalities correlates with extrahepatic clinical manifestations of HCV infection. In this context, cryoglobulinemic patients should be considered a peculiar HCV-infected population that needs a clinical multidisciplinary approach and more articulated therapeutic measures.

Abstract
Hepatitis C virus infection can lead to chronic active hepatitis, cirrhosis, and liver failure; however, it is also associated with a wide range of extra-hepatic complications. HCV is associated with a large spectrum of histopathological lesions in both native and transplanted kidneys, and it is increasingly recognized as an instigator of B cell lympho-proliferative disorders including mixed cryoglobulinemia. Mixed cyoglobulinemia is a systemic vasculitis primarily mediated by immune complexes; it is characterized by variable organ involvement including skin lesions, chronic hepatitis, glomerulonephritis, peripheral neuropathy, and arthralgias. The most frequent HCV-associated nephropathy is type I membranoproliferative glomerulonephritis, usually in the context of type II mixed cryoglobulinemia. Various approaches have been tried for the treatment of HCV-related glomerulonephritis, including immunosuppressive therapy (corticosteroids and cytotoxic agents), plasma exchange and antiviral agents. Data on the antiviral treatment of HCV-associated glomerulonephritis are not abundant but encouraging results have been provided. Immunosuppressive therapy is particularly recommended for cryoglobulinemic kidney disease. Recent evidence has been accumulated on rituximab therapy for HCV-related cryoglobulinemic glomerulonephritis exists but several questions related to its use remain unclear. Distinct approaches should be considered for the treatment of HCV-associated cryoglobulinemic glomerulonephritis according to the level of proteinuria and kidney failure.

Abstract
Vasculitides associated with anti-neutrophil cytoplasmic antibody (ANCA) serum positivity affecting small and medium-sized vessels are defined as ANCA-associated vasculitis (AAV). Glomerulonephritis in AAV is characterized by focal necrosis, crescent formation, and few or no immunoglobulin deposits. In vitro and animal evidence suggests that ANCA play a pathogenic role in AAV. Specific gene expression signatures are reported to predict long-term prognosis in AAV, suggesting the possibility of individualizing therapy and identifying new therapeutic targets. Although immunosuppressants and glucocorticoids are the cornerstone of AAV therapy, results from two recent randomized controlled trials have shown the non-inferiority of rituximab, compared with cyclophosphamide, for the induction of remission in patients with severe AAV. In fact, in April 2011, the US Food and Drug Administration (FDA) approved rituximab, combined with glucocorticoids, as a front-line therapy for adult patients with granulomatosis with polyangiitis (GPA; Wegener's granulomatosis) or microscopic polyangiitis. This new indication for rituximab provided the first ever FDA-approved therapy for these two diseases and the first alternative to cyclophosphamide for the treatment of severe disease in almost 40years. However, issues regarding the use of maintenance therapy after rituximab, the concurrent use of cyclophosphamide and the toxicity of rituximab remain unanswered and should be clarified in ongoing and future randomized controlled trials.
