Abstract
Direct antivirals showed dramatic response in hepatitis C virus (HCV) eradication, but their effect on extrahepatic manifestations is still unclear. A 49-year-old woman was referred to us suffering from lower limb edema and frothy urine. Renal biopsy was done and she was diagnosed with HCV-related membranoproliferative glomerulonephritis with cryoglobulinemia. Treatment with interferon plus ribavirin, steroid, and cyclophosphamide was tried but failed. After introduction of a sofosbuvir-based regimen to the treatment, sustained virologic response was achieved and nephrotic syndrome remission was induced successfully. We could conclude that HCV-related membranoproliferative glomerulonephritis with cryoglobulinemia could be treated successfully with immunosuppressive drugs plus sofosbuvir and dacalatasvir.

Abstract
RATIONALE Membranoproliferative glomerulonephritis (MPGN) can be induced by autoimmune diseases, chronic infection, chronic hepatitis, and paraproteins (including cryoglobulinemia). In addition, the mixed cryoglobulinemic MPGN is reported to be highly correlated with hepatitis C virus (HCV) infection. PATIENT CONCERNS We reported a rare case of a 61-year-old woman without a history of viral hepatitis infection; she presented with bilateral leg edema and proteinuria. Renal pathology revealed MPGN with multiple positive immunofluorescent staining. The consequent serum survey revealed positive cryoglobulin and monoclonal gammopathy of kappa type of immunoglobulin M. However, bone marrow study showed no obvious plasma cell proliferation, indicating that multiple myeloma was less likely. DIAGNOSES This patient's cryoglobulinemic MPGN could be related to monoclonal gammopathy of undetermined significance. INTERVENTIONS Oral immunosuppressant. OUTCOMES After steroid treatment, her renal function normalized and proteinuria kept in low level. LESSONS We demonstrated a rare cause of cryoglobulinemic MPGN without HCV infection, which led to a favorable prognosis after receiving steroid therapy. Moreover, the diagnosis of monoclonal gammopathy should be considered when facing such case and aggressive steroid therapy might be beneficial.

Abstract
Cryoglobulinemic vasculitis (CV) presents with systemic manifestations, including renal disease, arthritis, peripheral neuropathy, and muscle weakness. We encountered two patients who developed severe nephrotic range proteinuria; however, extrarenal manifestations were not noted during the clinical course. A renal biopsy revealed typical membranoproliferative glomerulonephritis (MPGN) with huge thrombus-like endothelial deposits and predominant IgM positivity, but electron microscopy did not reveal any definite microtubules. Immunosuppressive therapy and plasmapheresis were only partially effective, and the improvement was not durable. Biological therapy with rituximab (RTX) had no effect. Renal-limited CV should be recognized as a subset of essential CV.

Abstract
OBJECTIVES To investigate if indicators of a heavier involvement of mucosa-associated lymphoid tissue (MALT) in primary Sjögren's syndrome (pSS), i.e. persistent salivary gland (SG) swelling and cryoglobulinaemia, might better evaluate the lymphoma risk compared to the ESSDAI. Therefore, the current concept of disease activity of pSS should be re-evaluated, based solely on ESSDAI. METHODS A cohort of 255 pSS patients, including 30 pSS with B-cell lymphoma, was investigated. Three subgroups were distinguished, i.e. pSS developing lymphoma in the follow-up (n=12), pSS with lymphoma at cohort inclusion (n=18), and control pSS not developing lymphoma in the follow-up (n=225). SG swelling, cryoglobulinaemia and ESSDAI were evaluated at baseline, in the follow-up to one year before lymphoma diagnosis, and at lymphoma diagnosis. RESULTS SG swelling and/or cryoglobulinaemia at baseline were significantly higher (p=0.0003) in pSS patients evolving into lymphoma if compared to pSS controls, while ESSDAI showed no significant difference. Both SG swelling and cryoglobulinaemia persisted and sometimes developed ex novo in the follow-up. SG swelling and cryoglobulinaemia were present in 24/30 (80%) cases the time of lymphoma diagnosis, and lymphoma itself was usually of MALT/marginal zone histotype (90%), leading to peculiar manifestation of lymphoma in pSS. CONCLUSIONS The autoimmune and lymphoproliferative involvement of MALT is the biological substrate of pSS. If this involvement is heavier, as reflected by SG swelling and cryoglobulinaemia, disease activity may be considered higher, and the risk of lymphoma is increased. The current concept and evaluation of activity of pSS, based solely on the ESSDAI, needs revision.

Abstract
OBJECTIVES To investigate the long-term effects and safety of new direct anti-viral agents (DAAs) in patients with hepatitis C virus (HCV)-related mixed cryoglobulinaemia (MC) without renal involvement. METHODS The study enrolled 22 consecutive patients, 19 received sofosbuvir-based regimen and three patients received other DAAs, individually tailored according to latest guidelines. As of December 2016, the median length of follow-up was 17 months (range 13-21). RESULTS Extra-hepatic manifestations at enrollment were: purpura and arthralgia (12 cases), peripheral neuropathy (10 cases) and marginal zone B- lymphomas (2 cases). After a four-week DAA therapy, all patients became HCV- negative. Moreover, after 48 weeks since the beginning of DAA treatment, sustained regression of purpura and arthralgias was observed respectively in eight and in nine cases; peripheral neuropathy improved in seven cases, and cryocrit median values decreased from three (1-20) at baseline to two (1-12) after 48 weeks. Two cases with indolent marginal zone lymphomas did not show any haematological response: size and number of the involved nodes remained unchanged. In addition, the monoclonal B-cell population found in the peripheral blood in four cases did not disappear after recovery from HCV- RNA. Mild side effects occurred in nine patients, but six patients developed ribavirin-related anaemia requiring reduction of ribavirin dose. CONCLUSIONS DAA therapy is safe and effective to eradicate HCV in MC, but seems associated with satisfactory clinical response in mild or moderate cryoglobulinaemic vasculitis and no response in B-NHL.

Abstract
Cryoglobulinemia is defined as the presence of cryoglobulins in the blood. Cryoglobulinemia is often observed in the course of many diseases (infection, hematological disorders, autoimmune disorders) or has an idiopathic character. The classification of cryoglobulinemia is based on the immunological analysis of cryoglobulins and the activity of the rheumatoid factor (RF). The presence of cryoglobulins may induce cryoglobulinemic vasculitis (CV) which manifests with skin changes, arthritis and the dysfunction of internal organs. Diagnosis of cryoglobulinemia refers to the detection of cryoprecipitate in the blood serum sample. In the treatment of cryoglobulinemia various groups of medications may be used: corticosteroids, cyclophosphamide, azathioprine and rituximab. The purpose of the treatment is to reduce the production of cryoglobulins and the inflammation caused by their presence. Additionally, the treatment of organs complication is also crucial. If the viral infection is the causative agent of vasculitis, combination therapy will be recommended: antiviral and immunosuppressive therapy.

Abstract
Cryoglobulins are immunoglobulins that precipitate at cold temperatures. Their presence can be related to a type of vasculitis referred to as cryoglobulinemia. This condition, especially mixed cryoglobulinemia, has been associated with viral infections like hepatitis C virus in 60%-90% of cases, but it has also been reported in relation to connective tissue diseases, usually resulting in a more severe course. We describe the case of a patient with seronegative polyarthritis who developed acute arterial ischemia in association with cryoglobulinemia, with a good response to rituximab therapy.

Abstract
Systemic lupus erythematosus (SLE) patients may present with various symptoms and multisystem damage. We reported a 63-year-old male patient with SLE presenting as type B insulin resistance (TBIR) complicated with cryoglobulinemia. TBIR is an extremely rare disease, which is a manifestation of anti-insulin receptor antibodies (AIRA). Clinical feature is a sudden onset of hyperglycemia with major weight loss; however, the ensuing refractory hypoglycemia is more fatal. The average dosage of exogenous insulin is 5100 U/d. SLE patients with AIRA had poor prognosis, most of whom died of SLE activity. Cryoglobulins are immunoglobulins that reversibly precipitate in the cold, which will induce clinical symptoms. Non-infectious mixed cryoglobulinemia is frequently secondary to autoimmune diseases, such as SLE. Our patient was prescribed methylprednisolone (MP) and cyclophosphamide (CTX). Finally he had remission during the short-term follow-up. To our knowledge, this is the first case report of an SLE patient presenting as TBIR complicated with cryoglobulinemia.

Abstract
Background: There are no guidelines for the management of patients with cryoglobulins during cardiopulmonary bypass (CPB) necessitating core hypothermia. Objective: To evaluate a simple, pragmatic protocol of in vitro temperature-dependent cryoprecipitation of serum in patients with cryoglobulinemia before elective cardiac surgery with CPB. Methods: A 44-year-old female patient was known for chronic hepatitis C and type III cryoglobulinemia. Elective surgery was planned for an aortic arch aneurysm. A differential serum cryoprecipitation profile was established in vitro prior to surgery. Results: Whereas, at temperatures ≤15°C, cryoglobulin levels were ≥0.112 g/L (normal value <0.05 g/L), at 20°C and above, the precipitate was ≤0.016 g/L. Accordingly, surgery was performed without any cryoglobulin-related complications at an extracorporeal circulation temperature of 22-24°C, to minimise the risk of cryoprecipitation. Conclusion: In elective cases of surgery with CPB and hypothermia, temperature-dependent differential serum cryoprecipitation profile may be an easy and efficient way to assess a safe peroperative level of temperature to avoid complications due to cryoglobulins, without enhancing the patient's tissue ischemia risks.

Abstract
A 59-years old man, having untreated hypertension and diabetes, was admitted to our hospital because of lumbago and fever. A T2-weighted image of spine showed increased signal intensity of vertebra at L3 and L4. Methicillin-susceptible staphylococcus aureus (MSSA) infection was confirmed by blood culturing. Cerebrospinal fluid (CSF) analysis showed pleocytosis. Diagsosis of pyogenic spondylitis with bacterial meningitis was made. Diffusion-weighted magnetic imaging of the brain disclosed a focal hyperintense lesion in the corpus callosum which showed a low coefficient in the apparent diffusion coefficient mapping. This finding suggests a clinically mild encephalitis/encephalopathy with a reversible splenial lesion (MERS). His symptoms temporarily ameliorated by antibiotic therapy. Two weeks later, however, his conscious level rapidly worsened to comatose state. Concomitantly he developed acute renal failure with severe proteinuria. Serum serology showed a positive cryoglobulin test. Mechanical ventilation, hemodialysis and steroid pulse therapy improved his consciousness with a resultant complete recovery of all symptoms. We emphasize the possible complications in some cases of MERS.

Abstract
Chronic hepatitis C (CHC) is associated with multiple extrahepatic manifestations that may impact infected patients. The mechanisms through which these develop include those which are immunological, in which the chronic persistence of virus leads to the circulation of immune complexes (mixed cryoglobulinemia) and other autoimmune phenomena, and those which are virological and related to the extrahepatic tropism of the virus to other tissues. It is estimated that 40-74 % of patients with CHC may develop at least one extrahepatic manifestation during the course of the disease. Extrahepatic syndromes may represent the first signal of hepatitis C infection in some patients. CHC is associated with a four-fold increased risk of insulin resistance and type 2 diabetes mellitus; with cardiovascular disease in 17-37 % of patients; and with increased risk for cerebrovascular deaths, with a biological gradient of cerebrovascular mortality correlating with an increasing serum viral load. CHC is also associated with lymphoproliferative disorders, particularly non-Hodgkin B-cell lymphoma. The kidney is involved in 35-60 % of patients with CHC-associated mixed cryoglobulinemia. The prevalent type of glomerulonephritis associated with mixed cryoglobulinemia is membranoproliferative glomerulonephritis. In 30 % of cases, renal involvement begins with a nephritis syndrome and acute renal failure, while in 55 % there is only mild hematuria, microalbuminuria, proteinuria and renal insufficiency. CHC is also associated with cognitive impairment, especially in memory and concentration. Thus, extrahepatic CHC manifestations involve multiple organ systems outside the liver linked to a variety of comorbidities which may lead to significantly increased mortality from non-liver-related events.

Abstract
OBJECTIVES To investigate the expression of a VH1-69-encoded idiotype, and the phenotypic and functional features of monoclonal B-cells from patients with type II mixed cryoglobulinaemia (MC) secondary to chronic hepatitis B virus (HBV) infection. METHODS B-cell immunophenotype and expression of a VH1-69-encoded idiotype were investigated by flow cytometry. B-cell proliferative responses to stimuli were investigated by the CFSE dilution assay. RESULTS Two out of five patients with chronic HBV studied had massive monoclonal expansion of VH1-69-expressing B-cells. These cells had the peculiar CD21(low) phenotype and low responsiveness to stimuli typical of the VH1-69-expressing B-cells commonly expanded in MC secondary to hepatitis C virus (HCV) infection. In both patients, anti-HBV therapy led to the regression of MC and of VH1-69+ B-cell expansion. CONCLUSIONS VH1-69-encoded antibodies are known to preferentially recognise a variety of viral proteins including HCV E2, influenza A virus haemagglutinin and HIV gp41/gp120, and may serve as innate first line antiviral defense. Thus, like HCV, HBV may cause MC by protracted antigenic stimulation of VH1-69-expressing B-cells.

Abstract
Extrahepatic manifestations of hepatitis C virus infection (HCV) are very common. The most common of these is mixed cryoglobulinaemia. Anti-HCV antibodies and viral ribonucleic acid, HCV RNA, can be found in the cryoprecipitates, together with the rheumatoid factor. Cryoglobulins consist of a complex of immunoglobulins that in vitro precipitate upon the cooling bellow the human body temperature. Vasculitis is caused by the deposition of such immune complexes in the small blood vessels. A link with the HCV infection is considered to be established with membranoproliferative glomerulonephritis, leukocytoclastic vasculitis, lymphoproliferative disorders (in particular B cell lymphoma), Sjögren and sicca syndrome, lichen planus, porfyria cutanea tarda and diabetes mellitus. Very probable is the relationship of chronic HCV infection and thyroid disease, arthralgias, otherwise unexplained fatigue and autoimmune hepatitis.Key words: direct acting antivirals - extrahepatic manifestations - chronic hepatitis C - mixed cryoglobulinaemia.

Abstract
Utilizing genome-wide association studies (GWASs) to examine the variation in hepatitis C virus (HCV) phenotypes has led to quantum improvements in our understanding of both the genetic basis and the underlying pathogenesis of HCV infection. In this context, the discovery of interferon lambda polymorphisms is unique with far reaching implications that extend well beyond HCV to various other liver and extrahepatic diseases. In this review, we summarize the data on the impact of GWASs on our understanding of HCV disease.

Abstract
AIMS We retrospectively analyzed clinicopathologic features of 8 cases of hepatitis B virus-associated glomerulonephritis with hyaline thrombi, to confirm the diagnosis of cryoglobulinemic glomerulonephritis (CRYGN) associated with HBV infection. METHODS Retrospective analysis was carried out with demographic information, clinical manifestations, laboratory parameters, pathological and prognostic features. RESULTS The median age of 8 patients was 30.5 years (range, 21-75 years), including 6 males and 2 femles (M:F = 3:1). One patient had Raynaud's syndrome. Cryoglobulin testing was performed in 4 cases of our series, and 3 cases had elevated cryocrit (>256). Serum C4 decreased in all detected cases. Histopathologically, all cases showed hyaline thrombi occluded in capillary lumina; Co-deposit of IgG, IgM, IgA, Fib, C3d, C4d, C1q, HBsAg and HBcAb were identified in hyaline deposit/hyaline thrombi with polyclonal Igκ and Igλ staining. Ultrastructural examination confirmed the hyaline thrombi to be huge electron-dense bodies, which were a homogeneous texture. CONCLUSIONS The results suggest that 8 cases in the series are CRYGN associated with HBV infection. The incidence of CRYGN associated HBV was extremely low. Our series suggested that prognosis of CRYGN associated HBV was better in patients with mild symptoms, but it was poor in elder patients with severe vasculitis.

Abstract
Hepatitis C virus (HCV) has been recognized to be both a hepato- and lymphotropic virus. HCV lymphotropism represents an essential detail in the pathogenesis of virus-related autoimmune and lymphoproliferative disorders, ranging from clonal expansion of B-cells with organ and non-organ-specific autoantibody production up to overt non-Hodgkin’s lymphoma along a continuous step-by-step model of B-cell lymphomagenesis, where the intermediated mixed cryoglobulinemia could be considered as a stage of suppressible antigen-driven lymphoproliferation. The HCV long-lasting extrahepatic replicative state generates an abnormal systemic immunological response, including rheumatoid factor (RF) and cryo- and non-cryoprecipitable immune complexes, as well as clinical manifestations, comprising dermatitis, polyarthralgias and arthritis, pulmonary disease, aplastic anemia, glomerulonephritis and vasculitis. The mechanism of these extra-hepatic disorders is thought of as linked to immune complex disease, but their pathogenesis is poorly clarified. Immune-suppressive treatment could induce high-level hepatitis C viremia and impair hepatic disease. We report a female patient, whose chronic HCV-related liver cirrhosis with associated explosive, but oligosymptomatic lymphoproliferative immune response, i.e., RF beyond three thousand times the upper of normal range (unr), type II cryoglobulinemia with cryocrit 40% and monoclonal gammopathy IgM-k, has been successfully and safely treated by long-lasting (sixty-six months) combined antiviral therapy (pegylated interferon alfa and ribavirin), at moderate and tapering dose regimen, prolonged for nearly 24 months after the first viral suppression. At the last follow-up (fifty-one months), the patient was showing very-long term antiviral response, progressive decline of secondary immune activation and absence of significant side-effects. Further research is required to fully verify the real impact on therapeutic choice/regimen.

Abstract
Cryofibrinogen (CF) is a type of cryoprotein (CP) that can precipitate in cooled plasma but not in serum, and resolves upon warming. We identified a case of secondary cryofibrinogenemia with cholangiocarcinoma and deep venous thrombosis. The patient's cryocrit measured using a Wintrobe tube was 19% in sodium citrate plasma stored for 7 days at 4 degrees C. We performed quantitative analysis of plasma proteins (fibrinogen, IgG, IgA, IgM, C3, C4, α1-antitrypsin, and C-reactive protein) before and after precipitation for 12 hours at 4 degrees C. The plasma fibrinogen concentration decreased by 16.7% (120 mg/dL --> 100 mg/dL), whereas the others were unaffected by precipitation. The CP purified from the patient's plasma was washed three times with saline and subjected to Western blot and Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoresis (SDS-PAGE) analyses. Western blot analysis indicated that the purified CP was composed of not only fibrinogen but also fibronectin, α1-antitrypsin, α2-macroglobulin, coagulation factor VIII, and IgG, IgA, and IgM. Interestingly, SDS-PAGE analysis showed that the molecular weight of the patient's CF differed from that of purified normal fibrinogen (340 KDa) and consisted of several low-molecular-weight bands (50-250 KDa). From these results, we speculated that CF found in this case was a mixture of degradated fibrinogen and some plasma proteins. In summary, cryofibrinogenemia is a rare and under-recognized disease. Sample information in routine clinical practice is valuable to diagnose this disease.
