CIDP) can be defined as a spectrum of different clinical phenotypes which are characterized by autoimmune, inflammatory and demyelinating injuries, primarily affecting the peripheral nerves and nerve roots. Most patients with CIDP have a chronic course of neurological disability, but about a third of cases exhibit a relapsing-remitting course. Classic phenotype of CIDP involves symmetric compromise of proximal and distal muscle strength and sensitivity, associated with generalized areflexia. For an accurate diagnosis, demonstration of nerve demyelination by electromyography or nerve biopsy is required. Due to the affectation of relatively young, labor-active people and the high risk for neurological disability by the disease, treatment should be initiated early. The predominant lines of therapy, in its initial phase, are high-dose intravenous corticosteroids, intravenous immunoglobulin and plasmapheresis, while the maintenance therapy is mainly based on lowdose oral corticosteroids. This article presents a case report of a patient evaluated in our hospital and diagnosed with CIDP and exposes an updated literature review about this disease.
