Intestinal involvement of cryoglobulinemia is an uncommon manifestation and marker of severe vasculitis. We describe the case of a woman admitted to our service for management of acute renal failure and progressive gastrointestinal symptoms after initiating hepatitis C virus treatment with ribavirin and sofosbuvir 4 weeks prior. With an undetectable hepatitis C viral load and persistent symptoms despite hepatitis C virus therapy cessation, an upper endoscopy revealed duodenal sloughing, erythema, and bleeding, sparking suspicion for recurrence of cryoglobulinemic vasculitis...

BACKGROUND & AIMS: Cryoglobulins (circulating immune complexes of polyclonal IgG, monoclonal IgM, and rheumatoid factor) are detected in the circulation of 40% to 60% of patients with chronic hepatitis C virus infection, and cryoglobulinemic vasculitis (CV) is observed in approximately 10% of patients. We aimed to assess the clinical and immune effects of direct-acting antiviral treatment. METHODS: We performed a prospective study of 64 patients with HCV infection with circulating cryoglobulins receiving direct-acting antiviral therapy at a single center in Barcelona, Spain, from January 2014 through April 2016...

Mixed cryoglobulinemic vasculitis is associated with the monoclonal expansion of pathognomonic B cells in chronic hepatitis C. Recently, treatment with B-cell depletion, including rituximab, a CD20 monoclonal antibody, has been successful in achieving remission from the active disease. We investigated whether B-cell depletion therapy has an impact on activation of non-B cells in the periphery. Results demonstrated that B-cell depletion therapy is associated with a statistically significant decline in activated T cells, from pretherapy to follow-up while on rituximab therapy: CD4+ CD38+ HLA-DR+ (DR+), CD8+ CD38, CD8+ CD38+ DR+, and CD8+ DR+...

BACKGROUND: Cryoglobulinemia is an immune-complex-mediated small vessel vasculitis that classically involves the skin, kidneys and peripheral nerves. Antiphospholipid syndrome (APS) is an autoimmune hypercoagulable disorder which causes blood vessel thrombosis. It can present as a multi-organ microthrombotic disorder which is called catastrophic APS. OBJECTIVE: In this case series we aim to describe the diagnostic and management challenges that arise when these two severe disorders simultaneously present in the same patient...

Egypt, the single country with highest incidence of HCV infection in the world, has embarked on a government-sponsored mass treatment program using several combinations of DAAs. Recognizing the importance of extrahepatic manifestations, independently of the hepatic, a subcommittee was assigned to develop national guidelines for respective prioritizing indications and protocols. It evaluated the benefit of treating patients with different extrahepatic manifestations, and reviewed relevant clinical trials and guidelines concerning DAA combinations available in Egypt...

Cryoglobulins are monoclonal or polyclonal immunoglobulins that undergo reversible precipitation at low temperatures. Cryoglobulinemia is associated with HCV infection in more than 90% cases, the remaining 10% being called as Essential Cryoglobulinemia which is generally associated with a severe course and suboptimal response to conventional therapies. As the digital vessels are more prone to colder temperatures, hyperviscosity in those vessels can initiate local thrombosis and may manifest as ischemic ulceration and gangrene...

Inflammation mediated by cells of the immune system and necrosis are the most striking features observed at the histologic level in patients with vasculitides, clinical entities classified according to pathologic findings involving different organs, to etiology, or to size of vessels involved. Small vessel vasculitides (SVV) are a peculiar group of systemic disorders electively involving small intraparenchymal arteries, arterioles, capillaries, or venules and leading to different levels of vascular obstruction, tissue ischemia and risk of infarction; they can be divided into anti-neutrophil cytoplasmic antibody-associated vasculitides and immune complex vasculitides...

Cryoglobulinemic vasculitis is a disease of the small arteries and affects the skin, joints, peripheral nerves, kidneys and other organs. Even small amounts of cryoglobulins can lead to severe impairment for the patient but the detection of such low amounts of cryoglobulins can be difficult. The causes of cryoglobulinemic vasculitis include monoclonal hematological diseases, autoimmune diseases and chronic infections. Therapy involves treatment of the underlying disease and glucocorticoids, rituximab and plasmapheresis depending on the severity of the vasculitis...

Cryoglobulinemic vasculitis (CV) is a small-to-medium-vessel vasculitis that appears in 10-15 % of patients chronically infected with hepatitis C virus (HCV). The classic symptom triad of CV, purpura/asthenia/arthralgia, is accompanied by clinical features that include glomerulonephritis, neuropathy, interstitial pneumonitis, and cardiomyopathy, ranging in their severity from mild to life threatening. The risk of developing non-Hodgkin lymphoma is also higher. The cumulative 10-year survival rate of CV patients is significantly lower than in the age- and sex-matched general population, with death typically caused by nephropathy, malignancies, liver involvement, and severe infections...

Chronic hepatitis C (CHC) is significantly associated with a risk of renal deterioration over time. Renal impairment, especially stage 4-5 chronic kidney disease, increases the risk of: (i) the prevalence and incidence (in dialysis/transplantation) of hepatitis C virus (HCV) infection; (ii) liver deterioration during kidney transplantation and (iii) allograft failure and patient mortality. HCV-infected dialysis patients have a higher mortality than non-infected dialysis patients and than HCV-infected kidney recipients...

Approximately half of those with chronic hepatitis C virus (HCV) infection have circulating rheumatoid factor (RF), and a portion of these individuals develop cryoglobulinemic vasculitis. B cell phenotype/function in relation to RF in serum has been unclear. We examined B cell subset distribution, activation state (CD86), cell cycle state (Ki67), and ex-vivo response to BCR, TLR9 and TLR7/8 stimulation, in chronic HCV-infected donors with or without RF, and uninfected donors. Mature-activated B-cells of HCV-infected donors had lower CD86 expression compared to uninfected donors, and in the presence of RF they also showed reduced CD86 expression in response to BCR and TLR9 stimulation...
