Abstract
Background Glomerular involvement in rheumatoid arthritis has been known to be associated with treatment side effects from medications and secondary amyloidosis. However, limited basic science and clinical studies have been performed to address the potential disease specific immune-mediated mechanisms causing secondary glomerular pathology, its various types of presentation, and the potential treatments. Case presentation A 41-year-old man with chronic active rheumatoid arthritis presented with nephrotic syndrome and was found to have membranous nephropathy with eosinophilic intracapillary thrombi on renal biopsy. Proteinuria persisted despite complete withdrawal from non-steroidal anti-inflammatory drugs (NSAIDs) and disease-modifying anti-rheumatic drugs (DMARDs). Throughout the disease course, he developed cryoglobulinemic vasculitis and pulmonary sarcoidosis, both of which achieved clinical resolution with glucocorticoids. However, only partial improvement was observed in proteinuria with treatment of steroids and Rituximab. Conclusion Our case presented a unique and complicated clinical phenotype of active rheumatoid arthritis, with clinical features of cryoglobulinemic vasculitis, histopathologic features of membranous and cryoglobulinemic nephropathy in the absence of DMARDs use, as well as pulmonary sarcoidosis. We speculate that there is a wider spectrum of glomerular disease in patients with untreated rheumatoid arthritis. In addition, the potential association between rheumatoid arthritis and cryoglobulinemic vasculitis should probably be revisited and requires further studies to elucidate the underlying mechanisms and treatment options.

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
The skin is one of the most frequently involved organs in primary systemic and secondary vasculitis; moreover, a vasculitis can occur as single organ vasculitis, limited to the skin. For most types of vasculitis, the lower extremities constitute common sites with clinical symptoms of palpable purpura, nodules, and ulcers. In histopathology of cutaneous vasculitis, it is of utmost importance to correctly identify the vessel types involved and to discriminate between vasculitic vessel damage, unspecific reactive vessel changes, vascular occlusive diseases, noninflammatory purpura, or perivascular infiltrates due to other inflammatory skin diseases. Small-vessel vasculitis is the most frequent type of cutaneous vasculitis; during florid phases, a dermal leukocytoclastic vasculitis is found regardless of etiology. Additional extravascular changes may give etiological clues, however, a correlation with the clinical picture, radiology, and serology is essential. The biopsy type and technique need to be adjusted to the suspected diagnosis and site of the vessels involved. Polyarteritis nodosa and nodular vasculitis can be diagnosed only in biopsies with sufficient subcutaneous tissue. Especially in cutaneous ulcers, a lateral rim of vital skin and subcutaneous tissue is indispensable for a correct diagnosis. Large-vessel vasculitis is not found in skin biopsies of the lower extremities.

Abstract
Sjögren's syndrome (SS) is a chronic rheumatic autoimmune disorder affecting multiple organ systems. The clinical findings in SS patients show considerable heterogeneity and overlap with other autoimmune diseases. In addition, the autoimmune response in SS initiates several years before the appearance of clinical symptoms. Thus, understanding the pathogenic mechanisms involved in the disease process have been a challenge. Several animal model systems of SS-like disease have been developed to overcome these issues. The New Zealand Black (NZB) x New Zealand White (NZW) F1 (NZB/W F1) mouse represents the first spontaneous mouse model of SS. In this review, we provide a historical perspective and detailed description of this mouse model focusing on exocrine gland histopathology, autoantibody populations, and glandular dysfunction. Considering that NZB/W F1 mice also develop a systemic lupus erythematosus (SLE)-like disease, this mouse model mimics the clinical presentation of polyautoimmunity seen in a sizable subset of SS patients. It is plausible that such patients will require distinct therapeutic interventions necessary to treat both SLE and SS. Therefore, the NZB/W F1 mouse is a powerful tool to decipher pathogenic mechanisms involved in SS related polyautoimmunity and develop appropriate therapeutic strategies.

Abstract
Cryoglobulins are immunoglobulins that undergo reversible precipitation at cold temperatures. Monoclonal type-I cryoglobulinaemia is the least frequent and is associated to hematological diseases such as multiple myeloma, Waldenström's macroglobulinaemia, chronic lymphocytic leukaemia and lymphoma. We describe the case of a 60-year-old female patient, who suffered from burning pain in her feet for ten months before her admission. The patient presented intermittent distal cyanosis that progressed to digital ischaemia. She also reported paresthesia in her hands, difficulty in writing, and a 26-kg-weight loss. At the physical examination, it was identified livedo reticularis, palpable purpura, and painful ecchymotic lesions in her calves and feet. Moreover, peripheral pulses were palpable and symmetrical. It was observed an atrophy of the right first dorsal interosseous and both extensor digitorum brevis, as well as a distal bilateral apalesthesia and allodynia. Both Achilles reflexes were absent. Laboratory tests revealed anemia, high erythrosedimentation rate and C-reactive protein. Serum protein electrophoresis showed a monoclonal IgG-Kappa gammopathy. The results also evidenced the presence of Bence-Jones proteinuria. The bone marrow biopsy revealed less than 10% of plasma cells, and skin biopsy informed leukocytoclastic vasculitis. The patient was treated with high-dose intravenous steroids and cyclophosphamide. The treatment showed that the skin lesions had improved, pain disappeared and motor deficit stopped its progression.

Abstract
Cryoglobulinemic vasculitis is most commonly observed in the setting of hepatitis C infection. However, many other etiologies have been identified as well. We herein report a case of cryoglobulinemic vasculitis in a 56-year-old male secondary to infective endocarditis. The patient presented with a five-week history of a painful, purpuric rash and was found to have positive blood cultures, elevated cryoglobulins, and vasculitis on histology. He recovered after treatment with intravenous antibiotics and steroids. Although rarely identified as a cause of cryoglobulinemic vasculitis, infective endocarditis must be considered on the differential diagnosis as a delay in treatment can worsen the prognosis for the patient.

Abstract
BACKGROUND Hepatitis E virus (HEV) has been associated with immunological phenomena. Their clinical significance, however, still needs to be clarified, that is, whether cryoglobulins or autoantibodies impact overt disease in HEV-infected individuals. To better understand, we analyzed these different immune phenomena in three cohorts, each representing different types of HEV infection. METHODS The cohorts included: (i) immunocompetent patients with acute hepatitis E, (ii) immunosuppressed patients with chronic hepatitis E, and (iii) individuals with asymptomatic HEV infection. Together, they consisted of 57 individuals and were studied retrospectively for the presence of anti-nuclear antibodies (ANAs), cryoglobulins, and serum total IgG. They were then compared with a control cohort of 17 untreated patients with chronic hepatitis B virus (HBV) infection or hepatitis C virus (HCV) infection. RESULTS Thirteen (23%) were immunocompetent patients with acute hepatitis E (median alanine aminotransferase (ALT) = 872 U/L), 15 (26%) were immunosuppressed patients with chronic hepatitis E (median ALT = 137 U/L), and 29 (51%) were blood donors with asymptomatic HEV infection (median ALT = 35 U/L). Overall, 24% tested positive for elevated ANA titers of >1:160, and 11% presented with a specific ANA pattern. ANA detection was not associated with the type of HEV infection, IgG levels, sex, or age. All individuals tested negative for anti-mitochondrial antibodies, anti-neutrophil cytoplasmic antibodies, liver-kidney microsomal antibodies, anti-myeloperoxidase-, and anti-proteinase-3 antibodies. Five patients (9%) tested positive for cryoglobulins. Notably, cryoglobulinemia was present in overt hepatitis E (Groups (i) and (ii); one acute and four chronic HEV infections), but was not present in any of the asymptomatic blood donors (p = 0.02). The frequency of cryoglobulins and elevated ANAs did not differ significantly between HEV and HBV/HCV patients. CONCLUSION In line with findings on HBV and HCV infections, we frequently observed detection of ANAs (24%) and cryoglobulins (9%) in association with HEV infections. The presence of cryoglobulins was limited to patients with overt hepatitis E. We add to the findings on the immune phenomena of hepatitis E.

Abstract
We report a patient with IgM-predominant type I cryoglobulinemia (CG), who presented to our nephrology department with acute kidney injury. He was previously diagnosed with sensorimotor neuropathy, which was in remission with maintenance dose of corticosteroids. Upon admission, there were ulcerated, necrotic cutaneous lesions localized to the inner aspect of the thighs bilaterally. Further workup revealed a mucosa-associated lymphoid tissue lymphoma, causing type I CG. Screening tests for hepatitis viruses were negative at this time. Under treatment with diuretics and high-potency glucocorticoids, the patient had an acceptable recovery of renal function and was referred to oncology for treatment. Unfortunately, three months later the patient succumbed to fulminant hepatitis, presumably secondary to reactivation of an occult hepatitis B/D co-infection. We further conducted a literature review to better describe patient characteristics and renal involvement in type I CG.

Abstract
Infections are a frequent cause of cerebral vasculitis, important to diagnose because a specific treatment may be required. Infection-associated vasculitis can be caused by angiotropic pathogens (varicella zoster virus, syphilis, aspergillus). They can be associated with subarachnoidal meningitis (tuberculosis, pyogenic meningitis, cysticercosis). They can appear contiguously to sinuses or orbital infection (aspergillosis, mucormycosis). Finally, they also may be due to an immune mechanism in the context of chronic infections (hepatitis B virus, hepatitis C virus, human immunodeficiency virus). Cerebral vasculitis are severe conditions and their prognosis is directly linked to early recognition and diagnosis. Infectious causes must therefore be systematically considered ahead of cerebral vasculitis, and the appropriate investigations must be determined according to the patient's clinical context. We propose here an update on the infectious causes of cerebral vasculitis, their diagnosis modalities, and therapeutic options.

Prevalence of cryoglobulinemia and cryoglobulinemic vasculitis in chronically HCV-infected Brazilian patients. Ann Hepatol 2020; 18:685-692. [PMID: 31167733 DOI: 10.1016/j.aohep.2019.04.010] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/17/2018] [Revised: 04/16/2019] [Accepted: 03/13/2019] [Indexed: 02/06/2023]
Abstract
INTRODUCTION AND OBJECTIVES Cryoglobulinemia is one of the most frequent extrahepatic manifestations of chronic hepatitis C virus (HCV) infection and it may evolve to cryoglobulinemic vasculitis (CryoVas) which is a systemic vasculitis that affects small-sized vessels. The objective of this study was to evaluate the prevalence of cryoglobulinemia and CryoVas in HCV patients in São Paulo, Brazil. MATERIALS AND METHODS A cross-sectional study was conducted and included sixty-eight viremic HCV patients, without HIV or hepatitis B coinfection. A thorough clinical and laboratory evaluation was performed including the detection of serum cryoglobulins and measurement of serum complement components. The classification criteria for CryoVas were applied. RESULTS The study population comprised mainly women (61.8%) with long term HCV infection (median 11.0 years). Advanced hepatic fibrosis was detected in 20.6% (14/68) of cases. Cryoglobulins were detected in 48.5% (33/68) of HCV-patients with type III cryoglobulinemia being the most frequent. CryoVas was present in 10.3% (7/68) and the main manifestations were peripheral neuropathy (85.7%), palpable purpura (42.8%), arthralgias (42.8%) and renal involvement (42.8%). Life-threatening manifestations were rare. Low hemolytic C2, C4 and total hemolytic complement (CH100) levels were common findings in the cryoglobulinemia group. Low C4 levels were independently associated with the development of CryoVas. CONCLUSION A high prevalence of cryoglobulinemia and CryoVas was found in Brazilian HCV-patients. CryoVas patients mostly presented non-life-threatening manifestations, especially peripheral neuropathy. Complement abnormalities were common in patients with cryoglobulinemia and low serum C4 levels were associated with CryoVas.

Noninfectious mixed cryoglobulinaemic glomerulonephritis and monoclonal gammopathy of undetermined significance: a coincidental association? BMC Nephrol 2020; 21:293.

Abstract
Background Cryoglobulins are cold-precipitable immunoglobulins that may cause systemic vasculitis including cryoglobulinaemic glomerulonephritis (CGN). Type 1 cryoglobulins consist of isolated monoclonal immunoglobulin (mIg), whereas mixed cryoglobulins are typically immune complexes comprising either monoclonal (type 2) or polyclonal (type 3) Ig with rheumatoid activity against polyclonal IgG. Only CGN related to type 1 cryoglobulins has been clearly associated with monoclonal gammopathy of undetermined significance (MGUS) using the conventional serum-, urine- or tissue-based methods of paraprotein detection. Case presentation We present four patients with noninfectious mixed (type 2 or 3) CGN and MGUS. Two patients had type 2 cryoglobulinaemia, one had type 3 cryoglobulinaemia, and one lacked definitive typing of the serum cryoprecipitate. The serum monoclonal band was IgM-κ in all four cases. Treatments included corticosteroids, cyclophosphamide, plasma exchange, and rituximab. At median 3.5 years’ follow-up, no patient had developed a haematological malignancy or advanced chronic kidney disease. Other potential causes of mixed cryoglobulinaemia were also present in our cohort, notably primary Sjögren’s syndrome in three cases. Conclusion Our study raises questions regarding the current designation of type 2 CGN as a monoclonal gammopathy of renal significance, and the role of clonally directed therapies for noninfectious mixed CGN outside the setting of haematological malignancy.

Abstract
Monoclonal paraproteinaemia is an increasingly common reason for referral to haematology services. Paraproteinaemias may be associated with life-threatening haematologic malignancies but can also be an incidental finding requiring only observation. Immunoglobulin M (IgM) paraproteinaemias comprise 15–20% of monoclonal proteins but pose unique clinical challenges. IgM paraproteins are more commonly associated with lymphoplasmacytic lymphoma than multiple myeloma and can occur in a variety of other mature B-cell neoplasms. The large molecular weight of the IgM multimer leads to a spectrum of clinical manifestations more commonly seen with IgM paraproteins than others. The differential diagnosis of B-cell and plasma cell dyscrasias associated with IgM gammopathies can be challenging. Although the discovery of MYD88 L265P and other mutations has shed light on the molecular biology of IgM paraproteinaemias, clinical and histopathologic findings still play a vital role in the diagnostic process. IgM secreting clones are also associated with a number of “monoclonal gammopathy of clinical significance” entities. These disorders pose a novel challenge from both a diagnostic and therapeutic perspective. In this review we provide a clinical overview of IgM paraproteinaemias while discussing the key advances which may affect how we manage these patients in the future.

Abstract
Hepatitis B virus (HBV) is a hepatotropic virus that causes hepatitis, cirrhosis and hepatocellular carcinoma. Twenty percent of HBV patients may develop extra-hepatic manifestations, such as polyarthritis nodosa, glomerulonephritis, dermatitis, poly-arthralgia and arthritis, and aplastic anemia. The association of HBV and cryoglobulinemic vasculitis (CV) has been highlighted by several epidemiological investigations. CV can develop in 0.5-4% of HBV infected patients. It has been demonstrated that suppression of HBV replication by nucleot(s)ide analogues (NAs) effectively induces clinical response in most patients with mild to moderate CV, but low responses are seen in severe CV. Based on this evidence, NAs therapy represents the first line therapeutic option in subjects with mild or moderate HBV related CV. Peg-interferon-Alfa can be an alternative treatment for HBV related CV, but the few studies published so far have shown no encouraging results. In patients with severe vasculitis and/or skin ulcers, peripheral neuropathy and glomerulonephritis treatment with rituximab (RTX) and NAs should be considered as a first line treatment. The long-term administration of low-medium glucocorticoid doses has been widely used in few studies to control clinical symptoms, but it should be used as a second option, when RTX is ineffective or not tolerated and in association with NAs. This review focuses on novel treatments for HBV related CV.

Abstract
To explore the clinical characteristics and outcomes in Chinese patients with type I cryoglobulinemia (CG), we retrospectively analyzed the clinical data, management, and outcomes of 45 patients diagnosed with type I CG in our hospital from January 2015 to March 2019. In our study, all type I CGs were secondary to hematologic diseases, and monoclonal gammopathy of unknown significance was the most common primary disease, accounting for 48.9% (n = 22). Additionally, B cell non-Hodgkin lymphoma, Waldenström's macroglobulinemia, and multiple myeloma accounted for 24.4% (n = 11), 20.0% (n = 9), and 6.7% (n = 3), respectively. In patients with type I CG, skin damage was the most common symptom, presenting in 57.8% of the patients, followed by peripheral neuropathy (22.2%) and renal involvement (15.6%). Treatment was initiated in 29 patients (64.4%), and the most common choice was a rituximab-based regimen in 13 patients (44.8%), followed by bortezomib-based regimen in 11 patients (37.9%). Clinical symptoms were significantly improved after treatment, and the clinical remission rate was 86.2%, including 34.5% of complete clinical remission, while the laboratory response rate was 88.9%, including 33.3% of complete response and 55.6% of partial response. The expected 1-year overall survival was 97.8%. In conclusion, for patients with multisystemic involvement, such as skin damage, kidney damage, or peripheral neuropathy, the diagnosis of type I CG should be considered, and the underlying disease needs to be explored. Symptoms and primary diseases should be taken into consideration before choosing initial management.

Abstract
The cure of chronic hepatitis C infection has a major impact on the morbidity and mortality of infected patients. It is now clear that sustained virologic response improves overall survival and significantly reduces the risk of liver failure, fibrosis progression, need of liver transplantation, and incidence of hepatocellular carcinoma. Moreover, hepatitis C eradication improves a broad range of extrahepatic manifestations, such as dermatologic, neoplastic, cardiovascular, and endocrine, and improves quality of life.

Abstract
OBJECTIVES Historically chronic hepatitis C virus (HCV) infection accounted for the majority of mixed cryoglobulinemia (MC). The advent of direct-acting antivirals (DAA) against HCV has dramatically changed the management and the prevalence of chronic HCV infection. We aimed to describe the spectrum of MC in the era of DAA agents. METHODS We performed a longitudinal cohort study between 2011 and 2018 from a single-center French university hospital's database of 15 970 patients screened for MC. Epidemiological, clinical and immunological data of MC were recorded. We evaluated the incidence and evolution of MC before and after the era of DAA agents and compared HCV and non-HCV related MC. RESULTS Among 742 patients who tested positive for cryoglobulin, 679 [mean age 55.5 years, 54.5% female and 381 (56.1%) with chronic HCV infection] patients with persistent MC were included in the study. 373 (54.9%) had type II and 306 (45.1%) type III cryoglobulin, and 139 (21.5%) had cryoglobulinemia vasculitis (CryoVas). The incidence of MC decreased steadily with 395 and 284 incident cases during 2011-2014 and 2015-2018, respectively. In 2011, the leading cause was chronic HCV infection (62.5% of all MC). Currently, autoimmune diseases [systemic lupus erythematosus (28.9%) and Sjögren's syndrome (10.7%)] are the main cause of MC. The incidence of CryoVas was similar between HCV-and non HCV-related MC. CONCLUSION Direct-acting antivirals have dramatically changed the landscape and the incidence of MC.

Abstract
Autoantibodies to nuclear and cytoplasmic antigens are commonly detected by indirect immunofluorescence (IIF) on HEp-2 cells, and three major staining patterns (nuclear, cytoplasmic, and mitotic) are distinguished. Here, we report an atypical cytoplasmic pattern, not described so far, observed in the serum of a patient with a controversial diagnosis of systemic lupus erythematosus (SLE). Moreover, for the first time, we have revealed the presence of autoantibodies against the microtubule-associated light-chain 3 (LC3) protein, which plays a key role in the autophagic process. The target antigen has been identified in IIF by means of a competition test using purified anti-LC3 antibodies on HEp-2 cells, and confirmed by Western blot analysis using cellular or recombinant LC3 as antigen, immunoreacted with the patient's serum. The identification of this atypical pattern and the related autoantibody-antigen system sheds new light on autophagy, which is increasingly considered to be involved in the etiopathogenesis of autoimmune disorders, and could contribute to select more personalized therapies.

Abstract
Monoclonal gammopathy of renal significance (MGRS) is characterized by the nephrotoxic monoclonal immunoglobulin (MIg) secreted by an otherwise asymptomatic or indolent B-cell or plasma cell clone, without hematologic criteria for treatment. The spectrum of MGRS-associated disorders is wide, including non-organized deposits or inclusions such as C3 glomerulopathy with monoclonal glomerulopathy (MIg-C3G), monoclonal immunoglobulin deposition disease, proliferative glomerulonephritis with monoclonal immunoglobulin deposits and organized deposits like immunoglobulin related amyloidosis, type I and type II cryoglobulinaemic glomerulonephritis, light chain proximal tubulopathy, and so on. Kidney biopsy should be conducted to identify the exact disease associated with MGRS. These MGRS-associated diseases can involve one or more renal compartments, including glomeruli, tubules and vessels. Hydrophobic residues replacement, N-glycosylated, increase in isoelectric point in MIg causes it to transform from soluble form to tissue deposition, causing glomerular damage. Complement deposition is found in MIg-C3G, which is caused by an abnormality of the alternative pathway and may involve multiple factors including complement component 3 nephritic factor, anti-complement factor auto-antibodies or MIg which directly cleaves C3. The effect of transforming growth factor beta and platelet-derived growth factor-β on mesangial extracellular matrix is associated with glomerular and tubular basement membrane thickening, nodular glomerulosclerosis, and interstitial fibrosis. Furthermore, inflammatory factors, growth factors and virus infection may play an important role in the development of the diseases. In this review, for the first time, we discussed current highlights in the mechanism of MGRS-related lesions.

Abstract
GENERAL PURPOSE To discuss the pathogenesis and clinical features of wounds caused by microthrombi formation under the following categories of systemic diseases: cold-related and immune-complex deposition diseases, coagulopathies, abnormalities in red blood cell structure, emboli, and vasospasm. TARGET AUDIENCE This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care. LEARNING OBJECTIVES/OUTCOMES After participating in this educational activity, the participant should be better able to:1. Recall the etiology, risk factors, and pathophysiology of the various types of microthrombotic wounds.2. Describe the clinical manifestations and treatment of the various types of microthrombotic wounds. ABSTRACT Typical wounds such as diabetic foot ulcers, venous leg ulcers, pressure ulcers, and arterial ulcers are responsible for more than 70% of chronic wounds. Atypical wounds have broad differential diagnoses and can sometimes develop as a combination of different conditions. Regardless of the etiology, impaired blood circulation is characteristic of all chronic and acute wounds. Chronic wounds associated with microthrombi formation are an important group of atypical wounds commonly linked to an underlying systemic disease. In this perspective article, the pathogenesis and clinical features of wounds caused by microthrombi formation are discussed under the following categories of systemic diseases: cold-related and immune-complex deposition diseases, coagulopathies, abnormalities in red blood cell structure, emboli, and vasospasm.

Abstract
Objective To assess the prevalence and clinical features of neurologic involvement in patients with acute hepatitis E virus (HEV) infection in Southern Switzerland. Methods Among 1,940 consecutive patients investigated for acute hepatitis E, we identified 141 cases of acute of HEV infection (anti-HEV immunoglobulin M and immunoglobulin G both reactive and/or HEV RNA positive) between June 2014 and September 2017. Neurologic cases were followed up for 6 months. We compared patients with and without neurologic symptoms. Results Neurologic symptoms occurred in 43 acute HEV cases (30.4%) and consisted of neuralgic amyotrophy (NA, n = 15, 10.6%) and myalgia (n = 28, 19.8%). All NA cases were immunocompetent. Men had higher odds (OR = 5.2, CI 1.12–24.0, p = 0.03) of developing NA after infection with HEV, and in 3 couples simultaneously infected with HEV, only men developed NA. Bilateral involvement of NA was predominant (2:1) and occurred only in men. Seven NA cases were viremic (all genotype 3), but HEV was undetectable in their CSF. In the acute phase of NA, 9 patients were treated with intravenous immunoglobulin and 4 with prednisone, reporting no side effects and improvement in pain and strength. Myalgia occurred both without (n = 16) or with (n = 12) concomitant elevated serum creatinine kinase. Seven cases with myalgia in the shoulder girdle did not have muscle weakness (“forme fruste” of NA). Conclusions Neurologic symptoms occurred in one-third of acute HEV infections and consisted of NA and myalgia. NA seems to occur more frequently in men infected by HEV and has a predominant (but not exclusive) bilateral involvement.

Abstract
PURPOSE OF THE REVIEW Cryoglobulins are immunoglobulins with the ability to precipitate at temperatures <37 °C. They are related to hematological disorders, infections [especially hepatitis C virus (HCV)], and autoimmune diseases. In this article, the state of the art on Cryoglobulinemic Vasculitis (CV), in a helpful and schematic way, with a special focus on HCV related Mixed Cryoglobulinemia treatment are reviewed. RECENT FINDINGS Direct - acting antivirals (DAA) against HCV have emerged as an important key in HCV treatment to related Cryoglobulinemic Vasculitis, and should be kept in mind as the initial treatment in non-severe manifestations. On the other hand, a recent consensus panel has published their recommendations for treatment in severe and life threatening manifestations of Mixed Cryoglobulinemias. HCV-Cryoglobulinemic vasculitis is the most frequent form of CV. There are new treatment options in HCV-CV with DAA, with an important number of patients achieving complete response and sustained virologic response (SVR). In cases of severe forms of CV, treatment with Rituximab and PLEX are options. The lack of data on maintenance therapy could impulse future studies in this setting.

Abstract
Waldenstrom macroglobulinemia (WM) is a rare lymphoproliferative disorder characterized by the presence of monoclonal immunoglobulin M in serum. WM may present with neurologic complications involving the peripheral and central nervous systems (CNS) though CNS complications associated with WM are rare. We present a case of a 72-year-old male with an 18-month history of WM who experienced neurologic and constitutional symptoms indicative of WM progression over a three-week period while on rituximab maintenance therapy. The patient’s symptoms were initially attributed to rituximab-induced asthenia though his clinical condition did not improve with rituximab discontinuation. Due to progressively worsening neurologic symptoms, the patient was re-evaluated and found to have multiple cerebral infarcts and increased serum cryoglobulin levels indicative of cryoglobulinema. The patient was promptly initiated on a combination regimen of high dose steroids, intravenous immunoglobulin (IVIG), and plasmapheresis but had a poor response. Brain biopsy revealed necrotizing vasculitis with dense intra- and peri-vascular CD3 positive T-cell infiltrates with mural necrosis. This is a unique case of WM complicated by type 1 cryoglobulinemia associated with CNS vasculitis that was unresponsive to active rituximab therapy; this case illustrates a poor prognosis of patients with CNS involvement in WM.

Abstract
Rheumatoid arthritis is a systemic, polygenic, and multifactorial syndrome characterized by erosive polyarthritis, damage to joint architecture, and presence of autoantibodies against several self-structures in the serum and synovial fluid. These autoantibodies (anticitrullinated protein/peptide antibodies (ACPAs), rheumatoid factors (RF), anticollagen type II antibodies, antiglucose-6 phosphate isomerase antibodies, anticarbamylated protein antibodies, and antiacetylated protein antibodies) have different characteristics, diagnostic/prognostic value, and pathological significance in RA patients. Some of these antibodies are present in the patients' serum several years before the onset of clinical disease. Various genetic and environmental factors are associated with autoantibody production against different autoantigenic targets. Both the activating and inhibitory FcγRs and the activation of different complement cascades contribute to the downstream effector functions in the antibody-mediated disease pathology. Interplay between several molecules (cytokines, chemokines, proteases, and inflammatory mediators) culminates in causing damage to the articular cartilage and bones. In addition, autoantibodies are proven to be useful disease markers for RA, and different diagnostic tools are being developed for early diagnosis of the clinical disease. Recently, a direct link was proposed between the presence of autoantibodies and bone erosion as well as in the induction of pain. In this review, the diagnostic value of autoantibodies, their synthesis and function as a mediator of joint inflammation, and the significance of IgG-Fc glycosylation are discussed.

Abstract
OBJECTIVE Cryoglobulins are cold-precipitating immunoglobulins. Through progress in techniques, we undertook this study to update information on the biologic characteristics of cryoglobulins in a very large population. METHODS A cohort of 13,439 patients was tested for cryoglobulins from January 2010 to December 2016. The analysis included cryoglobulin isotype, clonality, concentration, and IgM rheumatoid factor (IgM-RF) in cryoprecipitate, as well as serum complement and RF. Markers of gammopathy, viral infection, and autoimmunity were also investigated. RESULTS Of the 13,439 patients, 1,675 (12.5%) tested positive for cryoglobulins: 155 patients (9.3%) with type I, 788 (47%) with type II, and 732 (43.7%) with type III cryoglobulins. Nine percent of patients who were retested after initially testing negative for cryoglobulins showed a positive result on a follow-up test (196 of the 2,213 retested patients). In type I cryoglobulins, IgM was more frequent but occurred at lower concentrations than IgG. Mixed cryoglobulins were found in 34.8% of the tested patients who were positive for hepatitis C virus and <5% of those who were positive for hepatitis B virus or HIV. Of the patients with anti-double-stranded DNA, anti-SSA, or anti-cyclic citrullinated peptide autoantibodies, 25.4% tested positive for mixed cryoglobulins, with type III occurring more frequently than type II. Both cryoprecipitate and serum were RF-positive in 21.6% of type II and 10.1% of type III cryoglobulins. A decrease of C4, with or without accompanying decreases of C3 and CH50, was found in 23.6% of cryoglobulin samples. CONCLUSION Obtained with the use of modern assays, our findings from this very large collection of cryoglobulins provide an update on cryoglobulin distribution and characteristics, with minimal selection bias. Despite strict preanalytical conditions, a negative finding for the presence of cryoglobulin must be confirmed in a second sample. RF activity and complement decreases were rarely detected.

Abstract
BACKGROUND The use of pegylated interferon alpha (IFN) has been of concern in chronic hepatitis C virus (HCV) patients with rheumatologic extrahepatic manifestations (EHM) due to the immunostimulatory effects of IFN. AIM To study the efficacy and safety of sofosbuvir-based, IFN-free antiviral therapy in chronic HCV patients with rheumatologic EHM. MATERIAL AND METHODS Group A included 24 patients with arthropathy (arthralgia or arthritis, n = 15) or vasculitis (n = 9) who received sofosbuvir and ribavirin (n = 17) or sofosbuvir and simeprevir (n = 7). Group B comprised 15 historical controls suffering from arthropathy who had received IFN and ribavirin. All patients were clinically evaluated and by detection of HCV viremia at baseline (V0), at the end of treatment (V1), 12 weeks after end of treatment (V2) and 24 weeks after end of treatment (V3). RESULTS Sustained viral response was obtained in all patients of group A (100%) versus 12 out of 15 of group B (80%). In group A, the tender joint count (TJC) and visual analogue scale for pain (VAS) improved (p = 0.001 for both) while the swollen joint count (SJC) decreased at V1 (p = 0.001) but returned to baseline values at V3. All vasculitis patients improved. Purpura, arthralgia and leg ulcers disappeared, but peripheral neuropathy persisted. In group B, TJC, SJC and VAS increased from baseline values (p = 0.034, 0.03 and 0.001, respectively). Side effects in group A were generally mild, but one patient developed deterioration of arthralgia. CONCLUSION The use of IFN-free regimens is safe and effective in the treatment of most HCV-related rheumatologic EHM.

Abstract
Cryoglobulinemic vasculitis (CV) can develop in 1.2-4% of hepatitis B virus (HBV)-infected patients. HBV infection affects about 350 million people worldwide. It can progress from acute or fulminant hepatitis to chronic hepatitis, cirrhosis or hepatocellular carcinoma. Twenty per cent of HBV patients may develop extra-hepatic manifestations, such as polyarteritis nodosa, glomerulonephritis, dermatitis, polyarthralgias and arthritis, lung disease, aplastic anaemia. Our review focuses on the role of antiviral agent nucleot(s)ide analogues (NAs) in treatment of HBV-related CV. The studies in literature have demonstrated that NAs therapy in HBV-related CV yields high virological and satisfying clinical responses in most patients with mild-and-moderate CV, but a low response in severe CV. Overall, NAs represent a promising therapeutic option for HBV-related CV. Obtaining early suppression of HBV viral load should be the main virological and clinical goal in order to prevent organ complications and lymphoproliferative disorders.

Abstract
Cryoglobulins are antibodies that precipitate at low temperatures and dissolve after rewarming. Cryoglobulinemia refers to the presence of circulating cryoglobulins and generally leads to a systemic inflammatory syndrome characterized by fatigue, arthralgia, purpura, ulcers, neuropathy and/or glomerulonephritis. The disease mainly involves small to medium-sized blood vessels and causes vasculitis due to cryoglobulin-containing immune complexes. Cryoglobulinemia is classified into three types (I, II and III) on the basis of immunoglobulin composition. Predisposing conditions include lymphoproliferative, autoimmune diseases and hepatitis C virus infection. The diagnosis of cryoglobulinemic syndrome is predominantly based on the presence of clinical features and laboratorial demonstration of serum cryoglobulins. The treatment strategy depends on the cause of cryoglobulinemia. For patients with chronic HCV infection, antiviral therapy is indicated. Immunosuppressive or immunomodulatory therapy, including steroids, plasmapheresis and cytotoxic agents, is reserved for organ-threatening manifestations. In this review, we discuss the main clinical presentations, diagnostic approach and treatment options.

Abstract
OBJECTIVE Cryoglobulinemia often causes systemic vasculitis, thereby damaging to skin and internal organs including kidneys, even life-threatening. This review aimed to introduce the advances in understanding, detection, and treatment of this disease in recent years, with a particular concern to clinical practice. DATA SOURCES All the data in this review were from the English or Chinese literature in the PubMed and China National Knowledge Infrastructure databases as of March 2019. STUDY SELECTION This review selected important original articles, meaningful reviews, and some reports on cryoglobulinemia published in recent years and in history, as well as the guidelines for treatment of underlying diseases which lead to cryoglobulinemia. RESULTS Diagnosis of cryoglobulinemia relies on serum cryoglobulin test, in which to ensure that the blood sample temperature is not less than 37°C in the entire pre-analysis phase is the key to avoid false negative results. Cryoglobulinemic vasculitis (Cryo Vas), including cryoglobulinemic glomerulonephritis (Cryo GN), usually occurs in types II and III mixed cryoglobulinemia, and can also be seen in type I cryoglobulinemia caused by monoclonal IgG3 or IgG1. Skin purpura, positive serum rheumatoid factor, and decreased serum levels of C4 and C3 are important clues for prompting types II and III Cryo Vas. Renal biopsy is an important means for diagnosis of Cryo GN, while membranous proliferative GN is the most common pathological type of Cryo GN. In recent years, great advances have been made in the treatment of Cryo Vas and its underlying diseases, and this review has briefly introduced these advances. CONCLUSIONS Laboratory examinations of serum cryoglobulins urgently need standardization. The recent advances in the diagnosis and treatment of Cryo Vas and GN need to be popularized among the clinicians in related disciplines.

Abstract
The color purple can be seen in several types of eruptions including inflammatory dermatoses like lichen planus, infectious dermatoses like ecthyma gangrenosum, neoplasms like Kaposi sarcoma, and vasculitis and vasculopathy. The current review focuses on the clinical appearance, pathophysiology, and treatment of several vasculitides and vasculopathies including capillaritis, cutaneous small-vessel vasculitis, immunoglobulin A (IgA) vasculitis, cryoglobulinemia, granulomatosis with polyangiitis, eosinophilic granulomatosis with polyangiitis, microscopic polyangiitis, polyarteritis nodosum, warfarin-induced skin necrosis, heparin-induced thrombocytopenia, purpura fulminans, antiphospholipid antibody syndrome, calciphylaxis, levamisole-induced vasculopathy, and thrombotic thrombocytopenic purpura. Dermatologists play a central role in treating patients with cutaneous vasculitis and vasculopathy and may have the opportunity to facilitate identification of systemic disease by diagnosing cutaneous vasculitis and vasculopathy.

Abstract
Cryoglobulinemia is a rare illness of cryoglobulin accumulation in the blood which can typically present with arthralgia, purpura, skin ulcers, glomerulonephritis, and peripheral neuropathy. It is classified as mixed cryoglobulinemia when cryoglobulins contain more than one immune component such as IgM rheumatoid factor and polyclonal IgG. Typically, it presents in the setting of clonal hematologic disease, viral infection, or certain connective tissue diseases. Herein, we report the case of a 24-year-old man diagnosed and treated as mixed cryoglobulinemia in the setting of juvenile idiopathic arthritis (JIA). Investigations for viral etiologies, including HBV, HCV, and HIV, and all serologic tests were negative. Additionally serum protein and urine protein electrophoresis did not reveal monoclonal gammopathy; however, testing for plasma cryoglobulins was positive, and qualitative analysis revealed a faint polyclonal pattern. Thus, he was diagnosed with cryoglobulinemia in the setting of JIA, which has not been reported in the literature before. He dramatically improved upon initiation of rituximab and methotrexate.

Abstract
INTRODUCTION hepatitis C virus (HCV) has several extra-hepatic manifestations including cryoglubulinemia. Cryoglobulinemia is defined as the abnormal presence in the blood of one or several proteins (cryoglobulins) that can precipitate at low temperatures. METHOD We conducted a cross-sectional analytical study in the Laboratory of Biology and in the Unit of Hepatology of the General Hospital in Douala (HGD) over a period of 6 months. All patients agreeing to participate to the study and with anti-hepatitis-C antibodies under treatment or not were enrolled. Cryoglobulins were detected using biuret method and the classification was performed using Brouet immunoelectrophoresis. A multivariate analysis was conducted, confounding factors such as age, sex and the length of time after Hepatitis C Virus screening were adjusted. RESULTS The study enrolled 116 patients. The average age of patients was 58.47±9.95 years. Male sex accounted for 50.86% of cases. Arthralgia was found in 69.80% of cases. Cryoglobulin was found in 63.80% of patients. After adjustment, female sex (OR =2.18; CI 95% [0,97-4,90]; p= 0.059), asthenia alone (OR =2.45;CI 95% [1,04-5,80]; p= 0.041), asthenia combined with arthralgia (OR =2.84;CI 95% [1,13-7, 10]; p= 0.026) and the presence of HCV RNA (OR =2.84;CI 95% [1,13-7,10]; p= 0.028) were factors independently associated with the presence of cryoglobulin. CONCLUSION The prevalence of cryoglobubin is high in patients with anti-hepatitis-C antibodies at the HGD. Simple biological methods are used to detect it. Cryoglobulin test in patients with HCV is essential in resource-limited countries.

Abstract
RATIONALE Type I monoclonal cryoglobulinemia is usually associated with lymphoproliferative disorders, such as monoclonal gammopathy of undetermined significance (MGUS), myeloma, chronic lymphocytic leukemia (CLL) and lymphoplasmocytic lymphoma (LPL). Clinical symptoms related to Type I cryoglobulin (CG) isotype often include skin, neurological and renal manifestations. PATIENT CONCERNS A 42-year-old woman who initially presented urticaria, palpable purpura in both her upper extremities and legs, eosinophilia and Raynaud phenomenon. Skin biopsy revealed eosinophil infiltration. Monoclonal immunoglobulin (Ig) G-κprotein was detected and CG was also positive. DIAGNOSES The patient was finally diagnosed as MGUS related Type I CG. INTERVENTIONS Cyclophosphamide-dexamethasone-thalidomide (CDT) therapy was initiated. OUTCOMES The treatment relieved the skin symptoms efficiently. LESSONS To our knowledge, this is a rare case of Type I cryoglobulinemic vasulitis with eosinophilia complicated by MGUS, and the effective treatment of cyclophosphamide combined with thalidomide and prednisone may provide a new therapeutic option for cryoglobulinemic vasulitis.

Hepatitis C virus (HCV) has been shown to affect many tissues other than liver. However, of the many extrahepatic manifestations (EMs) that have been associated with HCV, including cryoglobulinemia, lymphoma, insulin resistance, type 2 diabetes and neurological disorders, only a few have been shown to be directly related to HCV infection of extrahepatic tissues. HCV-triggered immune-mediated mechanisms account for most of the EMs. It is estimated that up to 74% of patients with chronic hepatitis C can develop at least one EM. All HCV patients with EMs should be considered for antiviral therapy, although not all will resolve with sustained virological response.

Abstract
Primary vasculitides are diseases with a wide variety of anatomical, clinical, radiological, and laboratory presentations. Primary vasculitides are difficult to diagnose because of the complexity of clinical presentation, which may lead to delayed treatment and increased financial costs of workup investigations involving non-essential tests. Our objective in the present study is to create an algorithm that helps diagnosis of Primary vasculitides. The algorithm presented in this article allows fast, simple and cost-effective diagnosis of primary vasculitides using just clinical concepts and a few laboratory tests.

Abstract
OBJECTIVES The prevalence and factors of hepatitis C virus (HCV) -associated mixed cryoglobulinaemia in Asia remain elusive, and we aimed to investigate these topics. METHODS An 8-year prospective cohort study was conducted in 678 consecutive Taiwanese individuals with chronic HCV infection (438 completed an anti-HCV therapy course). RESULTS Of 678 individuals, 437 (64.5%) had mixed cryoglobulinaemia and 20 (2.9%) had mixed cryoglobulinaemic syndrome. At baseline, IgM (cut-off >122 mg/dL), triglycerides and IgG levels, and HCV genotype 3 were independently associated with mixed cryoglobulinaemia. Rheumatoid factor (RF) levels were associated with mixed cryoglobulinaemic syndrome (cut-off >12.2 IU/mL). At 24 weeks post-therapy, the 362 individuals with a sustained virological response (SVR) had higher cured (106/362 (29.3%) versus 10/76 (13.2%), p = 0.003) and lower persistent (100/362 (27.6%) versus 33/76 (43.4%), p = 0.003) mixed cryoglobulinaemia rates than non-SVR patients. Among SVR patients, compared with baseline levels, RF, IgG and IgM levels decreased, except in individuals with new mixed cryoglobulinaemia. Pre-therapy IgM levels were associated with 24-week post-therapy new (95% CI of OR 1.002-1.023) and persistent (95% CI of OR 1.004-1.015) mixed cryoglobulinaemia in SVR patients. After up to 8 years, 24-week post-therapy IgM levels were associated with mixed cryoglobulinaemia in SVR patients (9/51; 17.64%; 95% CI of HR 1.004-1.011). Among 17 SVR patients with pre-therapy mixed cryoglobulinaemic syndrome, 5 (29.4%) had long-term mixed cryoglobulinaemia and 4 (23.5%) had mixed cryoglobulinaemic syndrome. CONCLUSIONS Over 60% of chronic HCV-infected individuals had mixed cryoglobulinaemia, and 17.64% of SVR patients had mixed cryoglobulinaemia 8 years post-therapy. Pre-therapy RF and IgM levels marked HCV-associated mixed cryoglobulinaemic syndrome and mixed cryoglobulinaemia, respectively.

Abstract
BACKGROUND Hepatitis C virus (HCV) infection causes many extrahepatic malignancies; whether it increases gastric cancer risk and the risk reverses after anti-HCV therapy remain elusive. METHOD A nationwide population-based cohort study of Taiwan National Health Insurance Research Database (TNHIRD) was conducted. In parallel, the risk factors and HCV-core-protein expressions were surveyed in gastric cancer patients from a tertiary care center. RESULTS From 2003 to 2012, of 11,712,928 patients, three 1:4:4, propensity-score-matched TNHIRD cohorts including HCV-treated (7545 patients with interferon-based therapy ⩾ 6 months), HCV-untreated (n = 30,180), and HCV-uninfected cohorts (n = 30,180) were enrolled. The cumulative incidences of gastric cancer [HCV-treated: 0.452%; 95% confidence interval (CI): 0.149-1.136%; HCV-untreated: 0.472%; 95% CI: 0.274-0.776%; HCV-uninfected: 0.146%; 95% CI 0.071-0.280%] were lowest in HCV-uninfected cohort (p = 0.0028), but indifferent between treated and untreated cohorts. HCV infection [hazards ratio (HR): 2.364; 95% CI: 1.337-4.181], male sex (HR: 1.823; 95% CI: 1.09-3.05) and age ⩾ 49 years (HR: 3.066; 95% CI: 1.56-6.026) were associated with incident gastric cancers. Among 887 (males: 68.4%; mean age: 66.5 ± 12.9 years, 2008-2018) hospitalized gastric cancer patients, HCV Ab-positive rate was 7.8%. None of the investigated factors exhibited different rates between HCV Ab-positive and Ab-negative patients. No HCV-core-positive cells were demonstrated in gastric cancer tissues. CONCLUSIONS HCV infection, male sex and old age were risk factors for gastric cancer development. HCV-associated gastric cancer risk might be neither reversed by interferon-based therapy, nor associated with in situ HCV-core-related carcinogenesis.

Recommendations for managing the manifestations of severe and life-threatening mixed cryoglobulinemia syndrome. Autoimmun Rev 2019; 18:778-785. [PMID: 31181326 DOI: 10.1016/j.autrev.2019.06.008] [Citation(s) in RCA: 26] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2019] [Accepted: 02/22/2019] [Indexed: 02/07/2023]
Abstract
OBJECTIVE Some of the manifestations of mixed cryoglobulinemia syndrome (MCS) can be severe or life-threatening, and should be rapidly contained but, as the therapeutic approaches to such conditions are largely based on anecdotal data, a consensus conference was organised by the Italian Group for the Study of Cryoglobulinemia (GISC) with the aim of providing a set of recommendations based on an in-depth survey of the available data and expert opinion. METHODS The consensus panel, which included specialists working in different medical fields involved in the management of MCS patients, was first asked to divide the manifestations of MCS into severe or life-threatening conditions on the basis of their own experience, after which a complete literature review was carried out in accordance with the Cochrane guidelines for systematic reviews. RESULTS Therapeutic plasma exchange (TPE) was considered the elective first-line treatment in the case of life-threatening manifestations of MCS (LT-MCS) and patients with severe clinical symptoms (S-MCS) who fail to respond to (or who are ineligible for) other treatments. The data supporting the combined use of cyclophosphamide and TPE were considered limited and inconclusive. High-dose pulsed glucocorticoid (GCS) therapy can be considered the first-line treatment of severe MCS, generally in association with TPE. Rituximab (RTX)-based treatments should be considered in patients with skin ulcers, peripheral neuropathy or glomerulonephritis, and in patients with persistent LT-MCS after TPE. In patients with hepatitis C virus-related MCS with S-MCS, viral eradication should be attempted as soon as a patient's condition allows the use of direct-acting antivirals.
