title: [Diagnosis and therapy of vasculitic neuropathy. Consensus statement of the German Centers for Neuromuscular Disease].
abstract: Vasculitic neuropathies are immune mediated diseases of the peripheral nervous system, in which inflammation of the blood vessels causes damage to the nerves. We distinguish neuropathies associated with primary and secondary systemic vasculitis, with rheumatic diseases, with malignant disorders, drug-induced vasculitis and the non-systemic vasculitic neuropathies (NSVN). The typical clinical picture consists in an asymmetric or multifocal, painful sensorimotor neuropathy with an acute, subacute or chronic course and acute relapses. Neurophysiology reveals an active, asymmetric, axonal sensorimotor neuropathy. The disorders usually respond to immunosuppressive treatment. A diagnosis of definite vasculitis can be made with evidence of vasculitis in a biopsy specimen. The absence of positive morphological evidence, however, does not exclude the diagnosis. There is no single laboratory test that can prove or exclude vasculitis, in NSVN even an elaborate panel of blood tests can show normal findings. Systemic vasculitis has an incidence of 4/100,000 per year and, untreated, has a poor prognosis, which is greatly improved by the use of immunosuppressive treatment. The prognosis of NSVN is generally better, although many patients need long term immunosuppression. Current treatment recommendations for vasculitic neuropathies are presented.
