Ischemic retinal vasculitis is an inflammation of retinal blood vessels associated with vascular occlusion and subsequent retinal hypoperfusion. It can cause visual loss secondary to macular ischemia, macular edema, and neovascularization leading to vitreous hemorrhage, fibrovascular proliferation, and tractional retinal detachment. Ischemic retinal vasculitis can be idiopathic or secondary to ...

The present study aimed to identify the involvement of critical genes in systemic vasculitis, to gain an improved understanding of the molecular circuity and to investigate novel potential gene targets for systemic vasculitis treatment. The dual‑color cDNA microarray data of GSE16945, consisting of peripheral mononuclear blood cell specimens from 13 patients with systemic vasculitis and 16 heal...

Factor VIII related antigen, an endothelial cell product, was markedly raised in systemic necrotising arteritis, reflecting disease activity, but was not raised in active cutaneous vasculitis. In rheumatoid arthritis high levels were only found in systemic vasculitis or Felty's syndrome, but in other connective tissue diseases increased levels were more frequently detected and usually related t...

BACKGROUND Systemic vasculitis may cause life threatening complications requiring admission to an intensive care unit (ICU). The aim of this study was to evaluate outcomes of systemic vasculitis patients admitted to the ICU and to identify prognosis factors. METHODS During a ten-year period, records of 31 adult patients with systemic vasculitis admitted to ICUs (median age: 63 y.o, sex ratio ...

Primary systemic vasculitides (PSV) in children belong to the most challenging conditions in paediatric rheumatology practice. The spectrum of vasculitis affecting children as well as their clinical presentations differ from that of adults. Apart from relatively common Henoch-Shönlein purpura and Kawasaki disease, chronic PSV are extremely rare in childhood. They include mainly childhood polyar...

OBJECTIVE ANCA has come to play an important role in diagnosing vasculitis. In selected populations c-ANCA/PR3-ANCA has a high specificity and sensitivity for vasculitis. In clinical practice, how individuals with c-ANCA/PR3-ANCA but without sufficient evidence of systemic vasculitis should be managed is unclear. We therefore retrospectively assessed the disease panorama and outcome in a consec...

Drug-induced vasculitis is a known side effect of prolonged treatment with several drugs. It is characterized by inflammation and cellular infiltration of small vessels and presence of anti-neutrophil cytoplasmic antibodies (ANCA). Propylthiouracil and hydralazine (anti-thyroid and antihypertensive drugs) are the drugs most commonly associated with drug-induced vasculitis. Small vessels of the ...

Vasculitis is defined as inflammation directed at vessels, which compromises or destroys the vessel wall leading to haemorrhagic and/or ischaemic events. Skin biopsy is the gold standard for the diagnosis of cutaneous vasculitis, whose manifestations include urticaria, infiltrative erythema, petechiae, purpura, purpuric papules, haemorrhagic vesicles and bullae, nodules, livedo racemosa, deep (...

Urticarial vasculitis is an uncommon from of cutaneous vasculitis and is extremely rare to present during childhood, especially in boys. It typically presents with multiple systemic inflammatory manifestations. Skin biopsy is needed to confirm the diagnosis. In this report a 10 years old Saudi boy with prolonged urticarial rash, fever, and arthritis is presented. His skin biopsy was consistent ...
