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...

Membranoproliferative glomerulonephritis associated with mixed cryoglobulinemia is the most common form of kidney disease observed in relation to hepatitis C virus (HCV) infection. Rituximab, a monoclonal antibody against CD20, is an effective treatment for severe and/or refractory HCV-related vasculitis and may evade the need for dialysis as in our patient.

Cryoglobulins are produced by the over-stimulated immune system of patients with hepatitis C virus (HCV). HCV-induced cryoglobulinemic vasculitis primarily affects small-sized vessels of systemic organs. The most common symptoms are purpura, joint pain, and peripheral neuropathy or Raynaud phenomenon. The blood tests of patients with HCV may exhibit raised erythrocyte sedimentation rate and C-reactive protein levels, positive rheumatoid factor and cryoglobulins, and decreased complement levels. Therapeutic options for HCV-induced cryoglobulinemic vasculitis, include anti-virals, Rituximab, steroids, immunosuppressant drugs, and plasma exchange...

Cryoglobulinemic vasculitis is a rare and frequently fatal type of myocarditis. Cardiac manifestations in type 1 cryoglobulinemic vasculitis have never been reported to our knowledge. We report a rare case of type 1 cryoglobulinemic vasculitis with cardiac involvement in a patient who experienced progressive heart failure during the diagnosis. The diagnosis was made by the presence of cryoglobulins and endomyocardial biopsy results. After bortezomib-containing treatments, plasma cryoglobulin levels returned to normal, and the patient's clinical condition gradually improved...

Mixed cryoglobulinemic vasculitis is associated with monoclonal B cell expansion in patients with chronic hepatitis C (HCV) infection. B cell depletion therapy using rituximab, a CD20 monoclonal antibody, has been successful in achieving remission from symptomatic disease. This study investigated whether B cell depletion therapy has an impact on activation of HCV-specific T cell phenotype and function. Nineteen patients with Hepatitis C mixed cryoglobulinemic vasculitis were treated with 4 cycles of rituximab (375 mg/m2 ) and variables were measured 6 months after therapy...

B cell depletion therapy using rituximab has been shown to be effective in achieving remission in patients with HCV-mixed cryoglobulinemic (MC) vasculitis. Previously, we have demonstrated abnormalities in peripheral immune cells involving neutrophils, chemotaxis, and innate immune activation among patients with HCV-MC vasculitis when compared to HCV patients without vasculitis. In this study, we evaluated the effect of B cell depletion therapy on transcriptional profiles of peripheral blood mononuclear cells before and after riruximab therapy, in order to unravel the pathogenic mechanism involved in HCV-MC vasculitis induced by abnormal B cell proliferation...

Chronic hepatitis C virus infection (HCV) can present with cryoglobulinemic vasculitis, which is primarily associated with type II/III cryoglobulins. Type I cryoglobulins are usually seen in lymphoproliferative disease, and large vessel involvement with this type of vasculitis is rare. A 70-year-old man with chronic HCV presented with abdominal pain, leukocytosis, and rash. Computed tomography angiography showed thickening of the abdominal aorta consistent with large-vessel vasculitis. He was found to have type I cryoglobulinemia and was treated with corticosteroids and ledipasvir/sofosbuvir with rapid resolution of his aortitis...

Most emergencies in dermatology comprise a variety of entities with a usually benign course. However, vasculopathies and vasculitis are not common, but they could represent respectively 1.9% and 4.4% of these entities according to some studies of Emergency Dermatology Department. They become an important disease which has to be identified early to establish appropriate management and treatment. Some of them are well known, such as the leukocitoclastic vasculitis, Schölein-Henoch, panarteritis nodosa, antineutrophil cytoplasmic antibody associated vasculitis, giant cell arteritis, cryoglobulinemic vasculitis and antiphospholipid syndrome...

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...

Thyroid involvement is a common condition that can be recorded during the natural course of different systemic rheumatic diseases, including the mixed cryoglobulinemia (MC) syndrome or cryoglobulinemic vasculitis. MC is triggered by hepatitis C virus (HCV) chronic infection in the majority of cases; it represents the prototype of autoimmune-lymphoproliferative disorders complicating a significant proportion of patients with chronic HCV infection. HCV is both hepato- and lymphotropic virus responsible for a great number of autoimmune/lymphoproliferative and/or neoplastic disorders...

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)...

Cryoglobulinemia can induce systemic vasculitis affecting various organs such as skin, peripheral nerves, and kidney. The disease can induce chronic organ failure and even be life-threatening. Cryofiltration has been applied for the treatment of cryoglobulinemic vasculitis. We have experienced four cases with mixed cryoglobulinemia showing severe and progressive clinical manifestations, including skin purpura, nephrotic syndrome, acute kidney injury, and peripheral neuropathy. Cryofiltration in conjunction with conventional pharmacological therapies appeared to be safe and effective...

Chronic hepatitis C virus (HCV) infection is burdensome in patients with chronic kidney disease and contributes to substantial liver-related and all-cause morbidity and mortality. HCV infection itself may cause kidney dysfunction, as exemplified through mixed cryoglobulinemic vasculitis. HCV is more prevalent in patients with significant kidney disease compared to the general population, and recent reports have shown inadvertent HCV transmission in U.S. hemodialysis centers. Further, HCV has been demonstrated to accelerate kidney dysfunction and is associated with worse clinical outcomes in patients with kidney disease...

In immunocompromised patients, Aspergillus infections are important causes of morbidity and mortality. We describe a patient with cryoglobulinemic vasculitis who developed disseminated invasive aspergillosis with thyrotoxicosis caused by Aspergillus fumigatus. The diagnosis was based upon radiological, microbiological and pathological findings. The patient was treated successfully with voriconazole and caspofungin treatment followed by total thyroidectomy. We provide an overview of published reports on Aspergillus thyroiditis with an emphasis on therapeutic approaches...

Troponin I (TnI) false positive results have been reported in patients affected by immune disorders. We report the case of a 74-year-old woman affected by cryoglobulinemic vasculitis, admitted to the Emergency Room because of a lipotimic episode. A marked elevation of TnI plasma concentration was confirmed in multiple determinations, despite the absence of symptoms or electrocardiogram findings suggesting myocardial infarction. TnI plasma concentration was reported normal after re-testing with a different commercial kit...

An elderly woman presented with a 3-month history of nonhealing, tender ulcers involving the right calf and both forearms. She denied any history of similar lesions or trauma. Two trials of oral antibiotics had led to no improvement. Her medical history was significant for rheumatoid arthritis treated with methotrexate, hydroxychloroquine, and prednisone. A review of clinical manifestations was otherwise negative for disease. Physical examination of the patient's right calf revealed two punched-out ulcers with central necrotic black eschars, underlying retiform purpuric pattern, and mild fibrinopurulent drainage (Figure 1)...

Cryoglobulinemia (CG) is detected in more than 50% of patients with chronic hepatitis C (CHC); however, only 15-25% of them develop cryoglobulinemic vasculitis (CV) that is a systemic vasculitis due to the formation of immune deposits, which affects small (less than medium-sized) vessels and which is frequently fatal for the patient. The causes of CG only in some patients with CHC and the pathogenesis of CV remain unstudied; however, the accumulated data allow one to identify the special contribution of the patient's genetic factors to the development of the disease...
