A study of three patients with amyotrophic lateral sclerosis and a polyneuropathy resembling CIDP.
Echaniz-Laguna A, Degos B, Mohr M, Kessler R,
We report three patients with a syndrome that fulfilled clinical and laboratory criteria for definite chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) who failed immunosuppressive treatment and eventually developed progressive amyotrophic lateral sclerosis (ALS). Mean disease duration was 23 months (13-38) before death. Two patients had a family history of ALS without mutations of the SOD1 gene. Postmortem examination in one patient showed an endoneurial infiltration of mononuclear cells in lumbar roots and distal and proximal peripheral nerves, mainly around myelinated fibers, with demyelination and axonal loss, consistent with CIDP. The spinal cord revealed severe neuronal loss in the anterior horn, axonal loss in the corticospinal tract, and large numbers of phagocytes in the anterior and lateral tracts, indicative of ALS. Whether demyelinating polyneuropathy was coincident with ALS or was a cause or consequence of motor neuron degeneration in these patients remains to be elucidated. This unusual combination may provide an important clue in elucidating the pathogenesis of ALS in some patients. Muscle Nerve, 2006.

The association between demyelinating neuropathy and amyotrophic lateral sclerosis (ALS) has been reported rarely. We report four patients who presented with clinical features and investigations suggestive of a neuropathy but who later progressed and received a final diagnosis of ALS according to the original El Escorial criteria. Three patients met the European Federation of Neurological Societies/Peripheral Nerve Society 2006 definition for "definite" chronic inflammatory demyelinating polyneuropathy (CIDP), as well as the American Academy of Neurology (AAN) 1991 and Nicolas et al.  electrodiagnostic criteria for CIDP. Two of them showed segmental demyelination on teased-fiber preparations and one had a raised cerebrospinal fluid protein level. Another patient met the Nicolas et al. CIDP criteria and presented with brachial plexus hyperintensity on T2-weighted magnetic resonance imaging, indicative of an inflammatory process. No significant objective response to immunomodulatory treatment was observed in any of these patients who all subsequently progressed unfavorably.

Elevated anti-Epstein-Barr virus (EBV) antibody levels are present in serum of Multiple sclerosis (MS) patients but literature lacks of studies comparing anti-EBV antibody levels between MS and other neurological diseases. We evaluate anti-VCA IgG and IgM, anti-EBNA1 IgG, anti-Cytomegalovirus IgG and IgM titres in serum and cerebrospinal fluid (CSF) of 267 MS, 50 Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP) and 88 Amyotrophic Lateral Sclerosis (ALS) patients. We found increased titres of anti-EBV-IgG in serum and CSF of MS subjects as compared to CIDP and ALS patients thus providing additional evidence for a possible involvement of EBV in MS
