Hypocomplementemic urticarial vasculitis syndrome (HUVS) is a rare type III hypersensitivity disorder characterized by urticarial vasculitis and prolonged hypocomplementemia. Individuals with HUVS may also have joint involvement, pulmonary manifestations, ocular disease, kidney inflammation, or any other form of organ involvement. Hypocomplementemia, the presence of C1q antibody in the serum, and urticarial vasculitis are the keys to the diagnosis of HUVS. Read More

Schnitzler's syndrome is a rare autoinflammatory disorder characterized by interleukin-1ß-mediated and neutrophil-dominated inflammation. Neutrophil extracellular traps (NETs) are web-like structures of decondensed chromatin, histones, and antimicrobial peptides released by neutrophils. NETs were initially described in the context of pathogen defense but are also involved in autoimmune-mediated skin diseases. Read More

Background: Multiple Sclerosis (MS) has been associated with several immune-mediated diseases but the mechanisms that explain such associations, as well as their implications in clinical practice and treatment are rarely discussed.

Case Presentation: We report the case of a patient with a history of MS since she was 27 years old, followed by a diagnosis of Hypocomplementemic Urticarial Vasculitis (HUV) seven years later. Several disease-modifying treatments for MS and HUV were used but with limited benefit in both diseases and significant MS progression. Read More

Background: Urticarial vasculitis (UV) is a clinicopathologic entity in which skin lesions resemble urticaria clinically but last more than 24 hours and resolve with residual purpura. In this study, we evaluated distinguishing histological features of UV from common urticaria to differentiate between these two entities.

Methods: During 1 year, 55 urticaria and 245 UV samples were assessed. Read More

Anti-C1q autoantibodies may be found in many conditions, most commonly in systemic lupus erythematosus (SLE) and hypocomplementemic urticarial vasculitis syndrome (HUVS), and are diagnostic markers as well as disease activity markers in lupus nephritis. Sera from patients with SLE and HUVS show partly distinct autoantibody reactivities to separated protein chains B and C of the first component of complement, C1q. These different binding specificities can be detected by Western blot analysis of the autoantibodies under reducing conditions. Read More

Background: Despite the current knowledge of UV, there is a lack of consensus among diagnostic criteria and management. In general, antihistamine therapy is regularly used for the symptomatic management of pruritus but does not control inflammation or alter the course of the disease. Monoclonal antibodies such as omalizumab (anti-IgE) have been proposed as a potential treatment for urticarial vasculitis. Read More

The complement system is a fundamental part of the innate immune system, playing a crucial role in host defense against various pathogens, such as bacteria, viruses, and fungi. Activation of complement results in production of several molecules mediating chemotaxis, opsonization, and mast cell degranulation, which can contribute to the elimination of pathogenic organisms and inflammation. Furthermore, the complement system also has regulating properties in inflammatory and immune responses. Read More

Systemic urticaria in a 64-year-old woman was diagnosed as leukocytoclastic vasculitis by a punch biopsy of the skin. Her physical findings improved after prescription of prednisolone at a dose of 20 mg/day, but the skin rash relapsed with renal dysfunction, proteinuria, and hematuria when the dose of prednisolone was reduced over a period of 9 months to 1 mg/day. She was admitted to our institute for further examination, when urinary protein and plasma creatinine levels were 0. Read More

Auto-inflammatory diseases are characterized by unexplained and recurrent attacks of systemic inflammation often involving the skin, joints, or serosal membranes. They are due to a dysfunction or dysregulation of the innate immunity, which is the first line of defense against pathogens. Early recognition of these diseases by the clinician, especially by pediatricians encountering such pathologies in pediatric patients, is primordial to avoid complications. Read More

Cutaneous vasculitides encompass a wide and heterogeneous group of diseases affecting skin blood vessels that are clinically characterized by polymorphic skin lesions, particularly including palpable purpura as well as urticarial and necrotic-ulcerative lesions, with possible, albeit rare, extracutaneous involvement. Cutaneous leukocytoclastic angiitis and urticarial vasculitis, which are the two prototypic and most common variants of this group, are usually idiopathic but may also be induced by different triggers, notably drugs and infections, or may manifest in association with systemic disorders, particularly lupus erythematosus. Vasculitis skin lesions can also occur during the chronic-relapsing course of systemic vasculitides, such as granulomatosis with polyangiitis and eosinophilic granulomatosis with polyangiitis, with which cutaneous vasculitides can share clinical and histological features.
