Article: Sensory chronic inflammatory demyelinating polyneuropathy: An under-recognized entity?
[show abstract] [hide abstract]
ABSTRACT: Introduction: Sensory chronic inflammatory demyelinating polyneuropathy (CIDP) can be difficult to diagnose. Method: We report 22 patients with chronic sensory polyneuropathy with ≥1 clinical sign atypical for chronic idiopathic axonal polyneuropathy (CIAP) but no electrodiagnostic criteria for CIDP. Results: Clinical signs atypical for CIAP were: sensory ataxia (59%), generalized areflexia (36%), cranial nerve involvement (32%), rapid upper limb involvement (40%), and age at onset ≤55 years (50%). Additional features were: normal sensory nerve action potentials (36%), abnormal radial/normal sural pattern (23%), abnormal somatosensory evoked potentials (SSEPs) (100%), elevated CSF protein (73%), and demyelinating features in 5/7 nerve biopsies. Over 90% of patients responded to immunotherapy. We conclude that all patients had sensory CIDP. Discussion: Sensory CIDP patients can be misdiagnosed as having CIAP. If atypical clinical/electrophysiologic features are present, we recommend performing SSEPs and CSF examination. Nerve biopsy should be restricted to disabled patients if other examinations are inconclusive. © 2013 Wiley Periodicals, Inc.Muscle & Nerve 02/2013; · 2.37 Impact Factor -
Article: A current view of the diagnosis, clinical variants, response to treatment and prognosis of chronic inflammatory demyelinating polyradiculoneuropathy.

ABSTRACT: We retrospectively analyzed 146 patients fulfilling the European Federation of Neurological Societies and the Peripheral Nerve Society (EFNS/PNS) criteria for definite chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) to (1) evaluate the relevance of these criteria, (2) assess the frequency of CIDP variants, and (3) determine the response to treatment and the prognosis. We found that 75% of these patients fulfilled the main EFNS/PNS clinical and electrophysiological criteria (type I). The remaining patients were diagnosed using laboratory tools as supportive criteria. The common form of CIDP represented 51% of patients. We observed a high frequency of the sensory variant (35% of patients) and the rapid onset form (18%). A positive response to treatment was observed in 87% of patients, with a similar efficacy of prednisone and IVIg. However, in the long term, 40% of treated patients remained dependent on treatment. The IVIg dependency rate was higher than the prednisone or plasma exchange dependency rate (55%, 18%, and 23%, respectively; p = 0.0054). Severe handicap was observed in 24% of patients.Journal of the Peripheral Nervous System 03/2010; 15(1):50-6. · 2.80 Impact Factor
