The result is a leukocytoclastic vasculitis. [2] This results in hypocomplementemia, a low C3 level in serum. [2] They can also cause more reactions, causing the typical symptoms of serum sickness. This is similar to a generalised Arthus reaction. [2]
Treatment should be directed towards the specific underlying cause of the vasculitis. If no underlying cause is found and the vasculitis is truly limited to the skin then treatment is primarily supportive. [13] Such treatment involves measures such as leg elevation, stockings, and topical steroids to relieve itching/burning. If the vasculitis ...
Arthus reactions (type III hypersensitivity reactions) are rarely reported after vaccination and can occur after tetanus toxoid–containing or diphtheria toxoid–containing vaccines. An Arthus reaction is a local vasculitis associated with deposition of immune complexes and activation of complement.
The symptoms of DRESS syndrome usually begin 2 to 6 weeks but uncommonly up to 8–16 weeks after exposure to an offending drug. Symptoms generally include fever, an often itchy rash which may be morbilliform or consist mainly of macules or plaques, facial edema (i.e. swelling, which is a hallmark of the disease), enlarged and sometimes painful lymph nodes, and other symptoms due to ...
Some of the most severe and life-threatening examples of drug eruptions are erythema multiforme, Stevens–Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), hypersensitivity vasculitis, drug induced hypersensitivity syndrome (DIHS), erythroderma and acute generalized exanthematous pustulosis (AGEP).

If there is doubt about the cause of the skin lesions, a biopsy of the skin may be performed to distinguish the purpura from other diseases that cause it, such as vasculitis due to cryoglobulinemia; on microscopy, the appearances are of a hypersensitivity vasculitis, and immunofluorescence demonstrates IgA and C3 (a protein of the complement ...

Hence, vasculitis, glomerulonephritis and arthritis are commonly associated conditions as a result of type III hypersensitivity responses. [ 11 ] As observed under methods of histopathology , acute necrotizing vasculitis within the affected tissues is observed concomitant to neutrophilic infiltration , along with notable eosinophilic deposition ...
