BACKGROUND & AIMS: Cryoglobulins (circulating immune complexes of polyclonal IgG, monoclonal IgM, and rheumatoid factor) are detected in the circulation of 40%-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 (DAA) treatment. METHODS: We performed a prospective study of 64 patients with HCV infection with circulating cryoglobulins receiving direct-acting anti-viral therapy at a single center in Barcelona, Spain from January 2014 through April 2016...

Hepatitis C virus (HCV) infection is responsible for both hepatic and extra-hepatic disorders (HCV-EHDs); these latter are correlated on one hand clearly with HCV lymphotropism causing immune-system dysregulation as well as with viral oncogenic potential, and on the other hand probably with chronic inflammatory status causing cardio-metabolic complications as well as neurocognitive disturbances. The spectrum of HCV-EHDs ranges from mild or moderate manifestations, such as arthralgia, sicca syndrome, peripheral neuropathy, to severe, life-threatening complications, mainly vasculitis and neoplastic complications...

Neurolymphomatosis is a rare neurological syndrome in lymphomas. It is reported as infiltration of peripheral nerves by lymphoma. It is important to distinguish neurolymphomatosis from other types of neuropathies, particularly infectious and inflammatory conditions. However, it is difficult to isolate a cancer-related inflammatory vasculitis and mononeuritis multiplex without definitive histopathologic examination. In this report, we describe a case of non-Hodgkin's lymphoma involving the peroneal nerve and presenting as neurolymphomatosis...

Acute retinal necrosis (ARN), secondary to herpes simplex encephalitis, is a rare syndrome that can present in healthy individuals, as well as immuno-compromised patients. Most cases are caused by a secondary infection from the herpes virus family, with varicella zoster virus being the leading cause of this syndrome. Potential symptoms include blurry vision, floaters, ocular pain and photophobia. Ocular findings may consist of severe uveitis, retinal vasculitis, retinal necrosis, papillitis and retinal detachment...

Anterior ischemic optic neuropathies (AIONs) represent a segmental infarction of the optic nerve head (ONH) supplied by the posterior ciliary arteries (PCAs). Blood supply blockage can occur with or without arterial inflammation. For this reason, there are two types of AIONs: non-arteritic (NA-AION), and arteritic (A-AION), the latter is almost invariably due to giant cell arteritis (GCA). GCA is a primary vasculitis that predominantly affects extracranial medium-sized arteries, particularly the branches of the external carotid arteries (including superficial temporal arteries - TAs)...

Syphilis has long been known as the great imitator. Its heterogeneity can manifest in the form of meningitis, space occupying gummas, vasculitis, strokes, cranial neuropathies, myelopathy, dementia, and seizures. The incidence has been rising with each year, mainly in men who have sex with men accounting for 83% of cases. With the coexistence of immunocompromised states, especially HIV (human immunodeficiency virus), the usually chronic and insidious course of tertiary neurosyphilis can be accelerated. Stroke can occur as a result of neurosyphilis in its meningovascular form, and the likelihood of this increases with HIV co-infection, especially in high-risk groups such as intravenous drug users and men who have sex with men...

BACKGROUND: Giant cell arteritis (GCA) is a systemic granulomatous vasculitis, primarily affecting medium-large arteries. It has a predilection for the aorta and its major branches, including the carotid and vertebral arteries. Ophthalmic artery involvement frequently leads to irreversible visual loss, and therefore GCA is one of the few true ophthalmic emergencies. GCA, although classified as a large vessel vasculitis, is known to affect smaller-sized vessels, resulting in a multiplicity of signs in the eye, some of which are often missed...

Vasculitis is a group of disorders characterized by inflammation and destruction of blood vessels, resulting in ischemic injury to the involved tissue. Sometimes, peripheral neuropathy is one of the first symptoms of systemic vasculitis. Although the classic form of peripheral nervous system vasculitis is mononeuritis multiplex, it can also present as a mononeuritis. In this case report, the patient presented with progressive rapid onset numbness in her right hand for 2 months. She underwent carpal tunnel decompression surgery with initial diagnosis of acute carpal tunnel syndrome but failed to respond to the surgery, and two month later, she presented with foot drop...

Cutaneous polyarteritis nodosa (CPAN) is characterized by a necrotizing vasculitis of small and medium-sized arteries in the skin, which can be associated with fever, arthralgia, myalgia, and neuropathy, but, unlike polyarteritis nodosa (PAN), there is no visceral involvement. CPAN is rare in childhood. We report two siblings who developed CPAN during childhood. Interestingly, both had Mediterranean fever gene (MEFV) mutation, i.e. heterozygous E148Q. They also shared HLA-A24, -DR15 alleles. Simultaneous occurrence of MEFV mutation and HLA alleles with CPAN has never been reported in Japan...

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...

Vasculitic neuropathies are caused by ischemic damage due to vessel wall inflammation. This damage may cause axonal degeneration leading to permanent neurological disabilities. Therefore, early initiation of effective treatment is crucial. For primary systemic vasculitis, a combined treatment of corticosteroid and immunosuppressive agents is recommended in the evidence-based guidelines as initial standard therapy for induction of remission. However, limited data are available regarding therapies for vasculitic neuropathies and it remains unclear whether combined treatment should be employed as an initial therapy for all patients with vasculitic neuropathies...

Non-systemic vasculitic neuropathy (NSVN) is a vasculitis confined to the peripheral nervous system. It is one of the most common causes of vasculitic neuropathy, along with microscopic polyangiitis and eosinophilic granulomatosis with polyangiitis (Churg-Strauss syndrome). It remains unclear whether this disease is truly an isolated nosological entity, or part of the spectrum of systemic vasculitides. Anti-neutrophil cytoplasmic antibodies (ANCA) are negative in NSVN even though the size of affected vessels in this disease is similar to that in ANCA-associated vasculitis...
