The possible occurrence of chronic inflammatory demyelinating polyneuropathy (CIDP) in association with an identified dysglobulinemic
status is recognized and a causal relationship between the two has been suggested. We had the opportunity to study 18 patients
presenting with CIDP and dysglobulinemia. This was an IgG monoclonal gammopathy (IgG MG) in 8 cases, an IgM monoclonal gammopathy
(IgM MG) in 8, an IgG-IgM biclonal gammopathy in 1 case and an IgM monoclonal cryoglobulinemia in another. A peripheral nerve
biopsy specimen was available for all patients and the morphological findings in these specimens in the cases of CIDP with
IgG MG or cryoglobulin did not differ from those without, whereas characteristic features were observed in the cases of CIDP
with IgM MG and anti-myelin associated glycoprotein activity.

We describe a patient with the previously unreported association of chronic inflammatory demyelinating polyneuropathy (CIDP) and myasthenia gravis (MG). Immunosuppressive treatment with azathioprine and prednisone achieved clinical and electrophysiological remission of MG and improvement of CIDP. As ophthalmoplegia occurs infrequently in CIDP, the possibility of MG should be considered when this sign is present in a patient with CIDP. Since current therapy with corticosteroids, plasma exchange and other immunomodulating agents is effective against both diseases, their association may be undereported. 相似文献

We report our preliminary experience of high-dose intravenous gammaglobulin in patients with chronic inflammatory demyelinating
polyneuropathy (CIDP) selected for inefficacy or severe side effects of steroid and immunosuppressive treatment. Our treatment
proved safe and effective, reversing the disability of CIDP, the improvement being temporally related to the commencement
of intravenous high-dose gammaglobulin. The possible mechanisms of action are discussed.
Riassunto Gli AA. riportano i risultati emersi dal trattamento con gammaglobuline e.v. ad alte dosi in quattro pazienti affetti da polineuropatia cronica infiammatoria demielinizzante (CIDP), selezionati in base alla inefficacia o alla comparsa di gravi effetti collaterali da corticosteroidi e/o immunosoprressivi. Il trattamento fu prontamente seguito in ogni caso da sensibile miglioramento clinico, particolarmente vistoso in due pazienti; nessun effetto collaterale o complicanza risultò evidenziabile. I possibili meccanismi d'azione delle immunoglobuline intere e.v. ad alte dosi vengono discussi.相似文献

This long-term follow-up study examined patients with chronic inflammatory demyelinating polyneuropathy (CIDP) and only sensory
symptoms at first presentation, with emphasis on the development of motor symptoms and long-term disability. From all CIDP
patients referred to our Department between 1987 and 1995, seven had only sensory symptoms at first clinical presentation.
These were investigated according to a standard protocol, including a quantified clinical neurological examination and nerve
conduction studies. The mean duration of the disease before weakness developed was 3.1 years, but varied considerably (0.8–6.3
years). At follow-up, weakness developed in five patients and persisted in three of them. Five patients were not seriously
incapacitated by their disease (Rankin 1 or 2), four of them being in remission now and one showing a very slow progression
of disease. Two patients were moderately disabled (Rankin 3); one had severe persistent sensory ataxia and only weakness during
relapses and one had stepwise progression and moderate weakness. Motor nerve conduction studies revealed that the most notable
worsening in the entire group of patients was a decrease in distal compound muscle action potential amplitudes, indicating
the development of distal conduction block or axonal degeneration. These findings show that CIDP with only sensory symptoms
is a transient clinical stage that precedes the appearance of weakness in about 70% of patients. The long-term prognosis does
not differ from that of patients with CIDP who have weakness at the beginning of the disease.

Up to 16% of chronic inflammatory demyelinating polyneuropathy (CIDP) patients may present acutely. We performed a retrospective chart review on 30 acute inflammatory demyelinating polyneuropathy (AIDP) and 15 acute‐onset CIDP (A‐CIDP) patients looking for any clinical or electrophysiological parameters that might differentiate AIDP from acutely presenting CIDP. A‐CIDP patients were significantly more likely to have prominent sensory signs. They were significantly less likely to have autonomic nervous system involvement, facial weakness, a preceding infectious illness, or need for mechanical ventilation. With regard to electrophysiological features, neither sural‐sparing pattern, sensory ratio >1, nor the presence of A‐waves was different between the two groups. This study suggests that patients presenting acutely with a demyelinating polyneuropathy and the aforementioned clinical features should be closely monitored as they may be more likely to have CIDP at follow‐up.

A patient with chronic inflammatory demyelinating polyneuropathy (ClDP) and centrel demyelinating disease is desoribed in whom striking nodular filling defects on multiple lumbar–sacral nerve roots, mimicking neurofibromata, were observed at myelography and magnetic resonance imaging. We suggest that these lesions are secondary to recurrent segmental demyelination and remyelination and that the differential diagnosis of this radiological feature should include CIDP. © 1994 John Wiley & Sons, Inc. 相似文献

ObjectiveFocal nerve enlargement is a characteristic finding in chronic inflammatory demyelinating polyneuropathy (CIDP). We performed this study to assess the distribution of nerve enlargement through ultrasonographic examination of peripheral nerves and to correlate the ultrasonographic findings with clinical features.MethodsTo compare the ultrasonographic features of 10 subjects with CIDP with those of 18 healthy controls, we bilaterally measured the cross-sectional areas (CSA) of the vagus, brachial plexus, musculocutaneous, median, ulnar, radial, sciatic, tibial, common peroneal, and sural nerves. We also analyzed correlations between CSAs and various clinical and electrophysiological features.ResultsMean CSAs were significantly larger in CIDP patients than controls, especially at proximal and non-entrapment sites. CSAs were significantly correlated with muscle strength at initial presentation, but not at the time of ultrasonography. The CSAs of the median and ulnar nerves at the mid-forearm, tibial nerve at 7 cm proximal to the medial malleolus, and sural nerve correlated with the nerve conduction velocity of the corresponding region.ConclusionUltrasonography revealed widely distributed nerve enlargement, especially in proximal regions and non-entrapment sites, in patients with CIDP compared with healthy controls. Nerve enlargement correlated well with the electrophysiologic function of the nerve, but not current clinical status.SignificancePattern analysis of nerve enlargement using ultrasonography is a supportive tool in the diagnosis of CIDP. 相似文献

ObjectiveAim of this study was to develop and evaluate the applicability of an ultrasound score (Bochum ultrasound score – BUS) in distinguishing chronic (CIDP) from acute inflammatory demyelinating polyneuropathy (AIDP).Methods
- •Step 1: For the development of BUS 75 healthy-controls, 20 CIDP, 20 AIDP patients underwent US 4.55 ± 3.5 and 3.4 ± 2.91 years, respectively after onset. After comparing the distribution pattern and frequency of pathological US changes between the two study groups, we developed BUS, summarizing the cross sectional area (CSA) of: (1) the ulnar nerve in Guyons’ canal, (2) the ulnar nerve in upper-arm, (3) the radial nerve in spiral groove, (4) the sural nerve between the gastrocnemius muscle.
- •Step 2: The BUS underwent blinded evaluation in further 10 CIDP, 21 AIDP patients 3.8 ± 2.7 and 2.3 ± 1.5 years, respectively after onset.
- •Step 3: The BUS underwent blinded, prospective evaluation in 8 patients with acute/subacute polyradiculoneuropathy (5 CIDP, 3 AIDP) 2.6 ± 1.8 weeks after onset.

We describe a patient who concomitantly developed chronic inflammatory demyelinating polyneuropathy (CIDP) and myasthenia gravis (MG) following cytomegalovirus (CMV) infection. Whereas CIDP and MG presumably have different immunopathogeneses, a number of reports presented cases with CIDP and MG, some of which were concomitant cases. Several reports described association between CIDP or MG, and CMV infection, although the association is still a matter of controversy. This is the first report of patients with concomitant CIDP and MG following CMV infection. The association may be coincidental, but the possibility that CMV infection triggered development of both CIDP and MG simultaneously cannot be excluded. 相似文献

Summary Seven patients aged 29 to 76 years with various clinical subtypes of chronic inflammatory demyelinating polyneuropathy (CIDP) were investigated. Sural nerve biopsies were performed between 7 months and 19 years after onset of disease. Quantitative electron microscopy revealed involvement of primary unmyelinated fibers (UF) in all cases. When compared with age-matched controls from the literature and two controls of our own, there was an increase of degenerating primary UF in all cases, a definite decrease of density per mm2 or number per nerve after subtraction of regenerates of myelinated and unmyelinated fibers in five cases, an increase of denervated Schwann cell complexes of the unmyelinated type in three cases, and an increased incidence of a high ratio (3) of primary UF per Schwann cell complex in five cases. Presumably due to the small number and heterogeneity of cases, the results did not correlate with type and duration of CIDP, but were obviously influenced by the degree of demyelination. The possible causes of UF damage in CIDP are discussed. 相似文献
