الوصف: Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a rare and heterogeneous but treatable immune-mediated neuropathy. Nerve conduction studies are considered essential for a definite diagnosis, but poor performance and misinterpretation of the results frequently leads to misdiagnosis. Nerve ultrasound and MRI could be helpful in diagnosis. Whereas typical CIDP is relatively easy to diagnose, atypical variants with distinct phenotypes can be a diagnostic challenge. Intravenous or subcutaneous immunoglobulin, corticosteroids, and plasma exchange are effective treatments, but maintenance treatments are often required for years, and treatment regimens require careful and regular adjustments to avoid undertreatment or overtreatment. Patients who do not improve, or insufficiently improve after treatment, might have specific characteristics related to a distinct disease mechanism caused by immunoglobulin G4 antibodies to nodal or paranodal proteins, and could require alternative treatments. Future studies should focus on curative and individualised treatment regimens to improve the patient's condition and to prevent further nerve damage.

الوصف: International audience; BACKGROUND: Fingolimod is approved for the treatment of relapsing-remitting multiple sclerosis and was effective in experimental autoimmune neuritis in rats, a possible model for chronic inflammatory demyelinating polyradiculoneuropathy (CIDP). We aimed to evaluate the efficacy of fingolimod in delaying disability progression in patients with CIDP who withdrew from currently effective treatments (intravenous immunoglobulin [IVIg] or corticosteroids). METHODS: This double-blind, multicentre, randomised, placebo-controlled, parallel-group, event-driven study was done at 48 neurology centres in Australia, Canada, Israel, Japan, the USA, and nine countries in Europe. Participants with CIDP who were receiving IVIg or corticosteroids were randomly assigned (1:1) to once-daily oral fingolimod 0\textperiodcentered5 mg or placebo. Owing to the event-driven design, treatment duration was flexible and could be up to 4\textperiodcentered5 years. Randomisation was done with an automated interactive voice response-web response system and was stratified by Inflammatory Neuropathy Cause and Treatment (INCAT) disability scale scores. Previous IVIg treatment was discontinued after one final course ending the day before the first dose of fingolimod or placebo was given, whereas corticosteroids were tapered off over 8 weeks after randomisation. The primary endpoint was time to first confirmed worsening (>=1 point increase on the adjusted INCAT disability scale score versus baseline) and was assessed in the full analysis set, which consisted of all patients who underwent randomisation and had at least one efficacy assessment for the primary analysis. The survival distribution functions of time to first worsening were estimated within each treatment group according to the Kaplan-Meier survival distribution function and compared with a stratified log-rank test. The trial is registered with ClinicalTrials.gov, number NCT01625182. FINDINGS: Of 106 participants randomly assigned between Jan 24, 2013, and March 10, 2016, 54 received fingolimod (41 who had been receiving IVIg and 13 who had been receiving corticosteroids) and 52 received placebo (41 who had been receiving IVIg and 11 who had been receiving corticosteroids). The trial ended for futility as recommended by an independent data monitoring committee after an interim analysis when 44 confirmed worsening events had occurred. At the end of the study, the survival estimate of the proportion of participants free from confirmed worsening was not significantly different between the fingolimod group (42%, 95% CI 23-60) and the placebo group (43%, 28-59; p=0\textperiodcentered91). Adverse events occurred in 41 (76%) participants receiving fingolimod and 44 (85%) on placebo, and serious adverse events occurred in nine (17%) and four (8%) patients, respectively. The most common adverse events with fingolimod were headache (12 [22%] patients), hypertension (ten [19%]), and extremity pain (seven [13%]). Adverse events leading to study discontinuation occurred in seven (13%) participants on fingolimod and none on placebo. INTERPRETATION: Fingolimod 0\textperiodcentered5 mg once-daily was not better than placebo for the treatment of CIDP. Future trial designs should take account of the possibility that if IVIg is stopped abruptly, some patients might relapse soon afterwards whereas others might remain in remission.

الوصف: Item does not contain fulltext OBJECTIVE: Sporadic late-onset nemaline myopathy (SLONM) is a rare, late-onset myopathy that progresses subacutely. If associated with a monoclonal gammopathy of unknown significance (MGUS), the outcome is unfavorable: the majority of these patients die within 1 to 5 years of respiratory failure. This study aims to qualitatively assess the long-term treatment effect of high-dose melphalan (HDM) followed by autologous stem cell transplantation (SCT) in a series of 8 patients with SLONM-MGUS. METHODS: We performed a retrospective case series study (n = 8) on the long-term (1-8 years) treatment effect of HDM followed by autologous SCT (HDM-SCT) on survival, muscle strength, and functional capacities. RESULTS: Seven patients showed a lasting moderate-good clinical response, 2 of them after the second HDM-SCT. All of them had a complete, a very good partial, or a partial hematologic response. One patient showed no clinical or hematologic response and died. CONCLUSIONS: This case series shows the positive effect of HDM-SCT in this rare disorder. Factors that may portend an unfavorable outcome are a long disease course before the hematologic treatment and a poor hematologic response. Age at onset, level and type of M protein (kappa vs lambda), and severity of muscle weakness were not associated with a specific outcome. CLASSIFICATION OF EVIDENCE: This study provides Class IV evidence that for patients with SLONM-MGUS, HDM-SCT increases the probability of survival and functional improvement.

الوصف: Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is the most common autoimmune neuropathy. The diagnosis depends on the clinical presentation with a progressive or relapsing course over at least 2 months and electrophysiological evidence of primary demyelination. Whereas typical CIDP is quite easily recognizable because virtually no other neuropathies present with both distal and proximal motor and sensory deficit, atypical CIDP, focal and multifocal variants in particular, may represent a difficult diagnostic challenge. CIDP very likely is an underdiagnosed condition as suggested also by a positive correlation between prevalence rates and sensitivity of electrophysiological criteria. Since no 'gold standard' diagnostic marker exists, electrophysiological criteria have been optimized to be at the same time as sensitive and as specific as possible. Additional supportive laboratory features, such as increased spinal fluid protein, MRI abnormalities of nerve segments, and in selected cases nerve biopsy lead to the correct diagnosis in the large majority of the cases. Objective clinical improvement following immune therapy is also a useful parameter to confirm the diagnosis. The pathogenesis and pathophysiology of CIDP remain poorly understood, but the available evidence for an inflammatory origin is quite convincing. Steroids, intravenous immunoglobulin (IVIG), and plasma exchange (PE) have been proven to be effective treatments. IVIG usually leads to rapid improvement, which is useful in severely disabled patients. Repeat treatment over regular time intervals for many years is often necessary. The effect of steroids is slower and the side-effect profile may be problematic, but they may induce disease remission more frequently than IVIG. An important and as of yet uncompletely resolved issue is the evaluation of long-term outcome to determine whether the disease is still active and responsive to treatment.

الوصف: This multicentre randomised double blind crossover trial tested the short term efficacy of intravenous immunoglobulin (IVIg) 2.0 g/kg given over 24 or 48 hours in patients with paraproteinaemic demyelinating neuropathy (PDN). Twenty-two patients were randomised and completed the trial. After 2 weeks, the overall disability grade decreased during both IVIg treatment and placebo but neither change was significant nor was the mean difference between the treatment effects. After 4 weeks the overall disability decreased by a mean of 0.55 [0.67] grades during the IVIg period (p = 0.001) while it was substantially unmodified during the placebo period. The mean difference between the treatment effects was significant (p = 0.05). Overall during the IVIg period 10 patients improved and 11 were stable and one got worse. During the placebo period 4 patients improved, 4 deteriorated and 14 were stable. Many secondary outcome measures, including Rankin scale, time to walk 10 metres, grip strength, sensory symptoms score were significantly better during IVIg treatment. Two serious adverse events occurred during the trial, both during placebo treatment. In conclusion the trial showed some short-term benefit of IVIg in about half of the patients confirming previous observation.
