INTRODUCTION. Plasma exchange is a technique used in the treatment of some neurological autoimmune disorders since the 80s, especially in acute conditions. In recent years new data about it use has been published in many diseases with autoimmune basis, expanding the range of use of this technique. Read More

AIM. To update the current indications of this technique in the treatment of neurological diseases. DEVELOPMENT. We conducted a thorough review of all articles about the efficacy of plasma exchange in the treatment of different neurological diseases published since the 80s. We have also carried out a detailed analysis of recommendations and evidence of the use of this procedure by analyzing the guidelines of different scientific societies. CONCLUSIONS. Plasma exchange has proven to be an effective alternative treatment with high grade scientific evidence in diseases such as Guillain-Barre syndrome, chronic inflammatory demyelinating polyneuropathy and myasthenia gravis. It has been effective in treating acute demyelinating episodes unresponsive to other therapies, neuromyelitis optica relapses and other central nervous system diseases induced by antibodies. In comparative studies with intravenous immunoglobulin efficacy of both therapies is similar. Comparative studies should continue to be conducted in order to better understand the mechanisms of action, prioritize indications and compare the cost-effectiveness ratio of both procedures.

Acute motor axonal neuropathy (AMAN) is a variant of Guillain-Barre syndrome. It has been reported to have no sensory symptoms and is diagnosed by typical electrophysiological findings of low-amplitude or unobtainable compound muscle action potentials with normal sensory nerve action potentials. However, the authors experienced atypical case of general electrophysiological findings of AMAN with pain and paresthesia and presented it. Read More

This case implies that clinician should be on the alert to atypical sensory symptoms from the classical presentation of AMAN even if the patient is diagnosed with AMAN electrophysiologically and should consider proper treatment options based on clinical presentations.

Peripheral neuropathy is a common complication of a variety of diseases and treatments, including diabetes, cancer chemotherapy, and infectious causes (HIV, hepatitis C, and Campylobacter jejuni). Despite the fundamental difference between these insults, peripheral neuropathy develops as a combination of just six primary mechanisms: altered metabolism, covalent modification, altered organelle function and reactive oxygen species formation, altered intracellular and inflammatory signaling, slowed axonal transport, and altered ion channel dynamics and expression. All of these pathways converge to lead to axon dysfunction and symptoms of neuropathy. Read More

The detailed mechanisms of axon degeneration itself have begun to be elucidated with studies of animal models with altered degeneration kinetics, including the slowed Wallerian degeneration (Wld(S)) and Sarm knockout animal models. These studies have shown axonal degeneration to occur through a programmed pathway of injury signaling and cytoskeletal degradation. Insights into the common disease insults that converge on the axonal degeneration pathway promise to facilitate the development of therapeutics that may be effective against other mechanisms of neurodegeneration.

Reports of acute onset of Guillain-Barré syndrome (GBS) after epidural anesthesia/analgesia after labor and cesarean delivery has raised concern of a correlation between GBS and the use of neuraxial anesthesia. We present a patient who developed bilateral lower extremity weakness and paraparesis within hours after removal of an epidural catheter for cesarean delivery. The clinical diagnosis was highly suggestive for GBS after magnetic resonance imaging, cerebrospinal fluid findings, electromyogram, and nerve conduction studies. Read More

We discuss the pathophysiological mechanisms suggested in previous case reports and describe the relationship between epidural analgesia and GBS.

Introduction: This article is part of the Focus Theme of Methods of Information in Medicine on "New Methodologies for Patients Rehabilitation". Objectives: For Guillain-Barré patients, motor rehabilitation programs are helpful at the onset to prevent the complications of paralysis and in cases of persistent motor impairment. Traditional motor rehabilitation programs may be tedious and monotonous, resulting in low adherence to the treatments. Read More

A Virtual Motor Rehabilitation system has been tested in Guillain-Barré patients to increase patient adherence and to improve clinical results. Methods: Two people with Guillain-Barré performed 20 rehabilitation sessions. We tested a novel system based on Motor Virtual Rehabilitation in three periods of time (baseline evaluation, final evaluation, and follow-up. In the training program, the participants carried out a specific treatment using the Active Balance Rehabilitation system (ABAR). The system is composed of customizable virtual games to perform static and dynamic balance rehabilitation. Results: Significant improvements in clinical results were obtained by both participants, with significant results in the static balance clinical test of the Anterior Reach test in the standing position and unipedal stance time. Other significant results were found in dynamic balance clinical tests in the Berg Balance Scale test and the 30-second Sit-to-Stand test. With regard to acceptance of the system, both patients enjoyed the experience, and both patients thought that this system was helpful for their rehabilitation. Conclusions: The results show that Virtual Motor Rehabilitation for Guillain-Barré patients provides clinical improvements in an entertaining way.

Paralytic rabies closely simulates Guillain-Barre syndrome or ascending myelitis often causing clinical dilemma. Two such patients were managed in our hospital whose magnetic resonance imaging (MRI) revealed characteristic findings revealing T2 hyper intensity in central spinal cord and in posterior brainstem and hypothalamus. These MRI findings are helpful in the diagnosis of rabies in appropriate setting. Read More

We also review the literature on MRI changes in paralytic rabies.

The consumption of immunoglobulins (Ig) is increasing due to better recognition of antibody deficiencies, an aging population, and new indications. This review aims to examine the various dosing regimens and research developments in the established and in some of the relevant off-label indications in Europe. The background to the current regulatory settings in Europe is provided as a backdrop for the latest developments in primary and secondary immunodeficiencies and in immunomodulatory indications. Read More

In these heterogeneous areas, clinical trials encompassing different routes of administration, varying intervals, and infusion rates are paving the way toward more individualized therapy regimens. In primary antibody deficiencies, adjustments in dosing and intervals will depend on the clinical presentation, effective IgG trough levels and IgG metabolism. Ideally, individual pharmacokinetic profiles in conjunction with the clinical phenotype could lead to highly tailored treatment. In practice, incremental dosage increases are necessary to titrate the optimal dose for more severely ill patients. Higher intravenous doses in these patients also have beneficial immunomodulatory effects beyond mere IgG replacement. Better understanding of the pharmacokinetics of Ig therapy is leading to a move away from simplistic "per kg" dosing. Defective antibody production is common in many secondary immunodeficiencies irrespective of whether the causative factor was lymphoid malignancies (established indications), certain autoimmune disorders, immunosuppressive agents, or biologics. This antibody failure, as shown by test immunization, may be amenable to treatment with replacement Ig therapy. In certain immunomodulatory settings [e.g., idiopathic thrombocytopenic purpura (ITP)], selection of patients for Ig therapy may be enhanced by relevant biomarkers in order to exclude non-responders and thus obtain higher response rates. In this review, the developments in dosing of therapeutic immunoglobulins have been limited to high and some medium priority indications such as ITP, Kawasaki' disease, Guillain-Barré syndrome, chronic inflammatory demyelinating polyradiculoneuropathy, myasthenia gravis, multifocal motor neuropathy, fetal alloimmune thrombocytopenia, fetal hemolytic anemia, and dermatological diseases.

Intravenous immunoglobulin (IVIg)-a preparation of polyclonal serum IgG pooled from thousands of blood donors-has been used for nearly three decades, and is proving to be an efficient anti-inflammatory and immunomodulatory treatment for a growing number of neurological diseases. Evidence from controlled clinical trials has established IVIg as a first-line therapy for Guillain-Barré syndrome, chronic inflammatory demyelinating polyneuropathy and multifocal motor neuropathy. IVIg is also an effective rescue therapy in some patients with worsening myasthenia gravis, and is beneficial as a second-line therapy for dermatomyositis and stiff-person syndrome. Read More

IVIg has been tested in some neurodegenerative disorders, but a controlled study in Alzheimer disease yielded disappointing results. Despite its widespread use and therapeutic success, the mechanisms of action of IVIg are poorly understood. Several hypotheses, based on the function of either the variable or constant IgG fragments, have been proposed to explain IVIg's immunomodulatory activity. This Review highlights emerging data on the mechanisms of action of IVIg related to its anti-inflammatory activity, especially that involving the cellular Fcγ receptors and Fc glycosylation. We also summarize recent trials in neurological diseases, discuss potential biomarkers of efficacy, offer practical guidelines on administration, and provide a rationale for experimental trials in neuroinflammatory disorders.

Guillain-Barré syndrome is an acute inflammatory demyelinating polyneuropathy. Infrequent loco-regional variants, like the pharyngeal-cervical-brachial, have been described. We report the case of a 63-year-old male admitted to the emergency department with cervical and upper limb weakness, inability to swallow and chew, he also presented a rapidly progressive acute respiratory failure due to weakness of the respiratory muscles secondary to the pharyngeal-cervical-brachial variant of Guillain-Barré syndrome. Read More

This variant, although unusual, presents a well-defined clinical pattern and diagnostic criteria, which is important in order to start an early treatment to improve the prognosis, not always favorable, to these patients.

Multiple sclerosis (MS) and neuromyelitis optica (NMO) are presumed to be an autoimmune disease in the central nervous system (CNS). Although lipids are most abundant components in the nervous system, it has been believed that cellular and/or humoral immunity to various myelin proteins causes these neuroinflammatory diseases. Recent research advances enable us to study lipids in the membranes and some key molecules involved in various neurological disorders including Guillain-Barré syndrome, Alzheimer's disease, Parkinson's disease, and prion disease, are localized in lipid rafts. Read More

In MS and NMO, the key molecules for the pathogenesis or the target molecules for the treatments of MS and NMO are also localized in lipid rafts. Here in this article, we highlight on the possible involvement of lipid rafts in the pathogenesis and treatment of MS and NMO and introduce our recent observation of aquaporin 4 regarding NMO.

Guillain-Barré syndrome (GBS) is an acute immune-mediated demyelinating polyradiculoneuropathy that could lead to disabilities if not properly treated. There are only limited data on the prognostic factors and complications when using double-filtration plasmapheresis in these patients. We reviewed the medical records of 60 GBS patients who underwent double-filtration plasmapheresis as the first-line therapy at a tertiary care teaching hospital. Read More

The severity of disease was evaluated at different time points using disability scores. Functional outcome was defined as good (GBS disability score 0 to 2) or poor (GBS disability score 3 to 6) at 28 days after admission. The cohort included 22 women and 38 men with a mean age of 50 ± 18 years. In univariate logistic regression analysis, potential factors associated with poor outcome include an older age (P = 0.101), the absence of preceding respiratory tract infection (P = 0.043), mechanical ventilation (P = 0.016), a lower hematocrit (p = 0.072), a lower serum sodium level (P = 0.153) and a higher disability score on admission (P < 0.001). In multivariate analysis, a higher disability score on admission was associated with a poorer outcome (OR, 5.61; 95% CI, 2.34 to 13.43; P < 0.001), whereas the presence of prodromal upper respiratory tract infection correlated with a better outcome (OR, 0.13; 95% CI, 0.03-0.59; P = 0.009). Among 60 patients, eleven (18.3%) have various complications attributed to plasmapheresis treatment. Six patients (10.0%) developed deep vein thrombosis and two experienced catheter-related infection (3.3%). Hypotension, allergy and hemolysis occurred in one patient each (1.7%). In conclusion, we describe our experiences of using DFPP in the treatment of GBS. The pretreatment severity score was the most significant predictor of treatment outcome, suggesting that early referral and timely treatment are important. Potential complications such as catheter-related infection and deep vein thrombosis should be monitored carefully.

Guillain-Barré syndrome, an acute polyradiculoneuropathy that presents with weakness and areflexia, is the most common cause of acute flaccid paralysis. In certain patients, respiratory failure is secondary to this disorder, eventually causing patients to require mechanical ventilation and experience additional complications due to diminished respiratory support and related mobility limitations. Prognoses for most of these cases are positive; treatment consists of basic support combined with plasmapheresis or administration of immunoglobulins. Read More


This study sought to describe the socio-demographic, clinical, laboratory and neurophysiological characteristics of patients with Guillain-Barré syndrome who were hospitalised in the Intensive Care Unit of the Neurological Institute of Colombia between 2006 and 2012.
This study presents a case series.
We surveyed 25 patients (32% female and 68% male) with Guillain-Barré syndrome and an average age of 54 years. Sixty per cent of these patients were admitted between days 3 and 7 after symptom onset; 64% had a history of respiratory infection and 20% had a history of intestinal infection. In addition, 84% of the patients presented with albuminocytological dissociation. We observed the following clinical subtypes of Guillain-Barré syndrome: inflammatory demyelinating polyneuropathy in 32%, acute motor-sensory axonal neuropathy in 28%, acute motor axonal neuropathy in 28%, and Miller Fisher syndrome in 12%.
In this descriptive study of a group of critical care patients with GBS, results depended on patients' clinical severity at time of admission. Our findings are similar to results published in the international literature.

Focused studies on cranial neuropathy in Guillain-Barré syndrome (GBS) and its prognostic implication are not done previously.
To study the clinical profile of GBS patients with special reference to cranial neuropathy and its prognostic implication.
The study included 61 patients with GB syndrome, fulfilling Asbury Cornblath's criteria for GB syndrome. Read More

A pre-designed semi-structured questionnaire was used to obtain data regarding demographic profile and clinical profile. All patients underwent detailed neurological examination, investigations including nerve conduction studies and CSF examination and treated according to the severity of the illness. Patients were followed up for 6 months. During analysis two groups were made depending on cranial nerve involvement, and compared with respect to various parameters.
Out of 61 patients 38 (62.3%) patients had cranial nerve palsies, in that 25 had multiple cranial nerve palsies, and 13 had single isolated nerve palsy. A majority of 30 (49.2%) had bulbar palsy, 28 (46%) had facial nerve palsy, and all had bilateral involvement except 3 patients who had unilateral palsy. Hypoglossal nerve involvement was seen in six (10%) patients and four (6.5%) patients had ophthalmoplegia. Only one had bilateral vestibulocochlear nerve palsy. On comparing various clinico-electrophysiological parameters among patients of GB syndrome with and without cranial nerve involvement, the presence of respiratory paralysis, IVIg and ventilatory support requirement had significant association with cranial nerve involvement in GBS.
Our study found a correlation between cranial nerve palsies and severity of the illness. Cranial nerve innervated muscles recover earlier as compared to distal limb muscles. No association was found between outcome at 6 months and cranial nerve involvement.

Evidence for seasonal variation in incidence and subtype of Guillain-Barré syndrome (GBS) is contradictory, but has implications for provision of neurological services and understanding pathogenesis.
We searched PubMed and EMBASE between inception and January 2014, including all studies reporting seasonal incidence of GBS. We included a retrospective cohort study of patients with GBS at the John Radcliffe Hospital, Oxford 2001-2012 and determined the seasonal variation in GBS incidence and length of stay. Read More

The incidence rate ratio (IRR) for winter versus summer was pooled across studies by fixed and random effects meta-analysis weighted by inverse variance, stratified by geographical region, infectious prodrome and GBS subtype.
Across 9836 patients from 42 studies there was a 14% increased risk of GBS in winter versus summer (IRR=1.14, 1.02-1.27, p=0.020), with significant heterogeneity between studies (I(2)=77%, p<0.0001), including significant seasonal variation in Oxford (n=140; p=0.037) for winter versus summer (IRR=1.92, 1.18-3.11, p=0.004) but a non-significantly reduced length of stay for winter versus other seasons (15 vs 21 days, p=0.08). Across all studies, there was greater seasonal variation with respiratory prodrome (IRR=3.06, 1.84-5.11, p<0.0001) than diarrhoeal prodrome (IRR=1.10, 0.60-2.00, p=0.76) and a greater incidence in winter in Western countries (IRR=1.28), the Far East (IRR=1.20) and Middle East (IRR=1.12), with a lower incidence in the Indian subcontinent (IRR=0.86) and Latin America (IRR=0.75).
Incidence of GBS was greater in winter than summer, but this was not evident in all geographical regions. This is likely to be related to regional variation in prodromal illnesses.

Managing emerging vaccine safety signals during an influenza pandemic is challenging. Federal regulators must balance vaccine risks against benefits while maintaining public confidence in the public health system.
We developed a multi-criteria decision analysis model to explore regulatory decision-making in the context of emerging vaccine safety signals during a pandemic. Read More

We simulated vaccine safety surveillance system capabilities and used an age-structured compartmental model to develop potential pandemic scenarios. We used an expert-derived multi-attribute utility function to evaluate potential regulatory responses by combining four outcome measures into a single measure of interest: 1) expected vaccination benefit from averted influenza; 2) expected vaccination risk from vaccine-associated febrile seizures; 3) expected vaccination risk from vaccine-associated Guillain-Barre Syndrome; and 4) expected change in vaccine-seeking behavior in future influenza seasons.
Over multiple scenarios, risk communication, with or without suspension of vaccination of high-risk persons, were the consistently preferred regulatory responses over no action or general suspension when safety signals were detected during a pandemic influenza. On average, the expert panel valued near-term vaccine-related outcomes relative to long-term projected outcomes by 3∶1. However, when decision-makers had minimal ability to influence near-term outcomes, the response was selected primarily by projected impacts on future vaccine-seeking behavior.
The selected regulatory response depends on how quickly a vaccine safety signal is identified relative to the peak of the pandemic and the initiation of vaccination. Our analysis suggested two areas for future investment: efforts to improve the size and timeliness of the surveillance system and behavioral research to understand changes in vaccine-seeking behavior.

The surveillance of acute flaccid paralysis (AFP) is a key strategy for monitoring the progress of poliomyelitis eradication and is a sensitive measure for detecting potential cases of poliomyelitis and poliovirus infection. This study was conducted to describe the characteristics of patients reported with AFP, and to evaluate the performance of the surveillance system in Kurdistan province, western Iran, using indicators recommended by the World Health Organization (WHO).
This observational study was conducted from January 2000 to December 2010 at the Kurdistan Center for Disease Control and the Department of Pediatrics. Read More

All children who fulfilled the WHO definition for AFP were included in our study. The stool samples of all the children were sent for poliovirus isolation. All the patients were evaluated for 60 days after the onset of symptoms to identify the signs of residual weakness.
One-hundred thirty nine children aged <15 years were reported to the Center for Diseases Control with AFP. In 138 (99%) stool samples no poliovirus was isolated. None of the patients was diagnosed as having acute poliomyelitis or polio-compatible paralysis. Guillain-Barré syndrome was the most frequent final diagnosis (79 cases) followed by Transverse Myelitis (7 cases) and Encephalitis (6 cases). By detecting 1.3 to 3.6 (mean 3.2) AFP cases per 100 000 population in Kurdistan during the study period, we achieved the WHO target for AFP surveillance. All performance indicators but one consistently met the WHO requirements and therefore demonstrated the effectiveness of the AFP surveillance program in Kurdistan.
The effective surveillance system in Kurdistan and its evaluation may serve as a model for the surveillance of other infectious diseases.

GARDASIL (Merck & Co., Inc., Whitehouse Station, NJ, USA) is a quadrivalent human papillomavirus (HPV4) vaccine. Read More

An epidemiological study was undertaken to evaluate concerns about the potential for HPV4 vaccination to induce serious autoimmune adverse events (SAAEs). The vaccine adverse event reporting system (VAERS) database was examined for adverse event reports associated with vaccines administered from January 2006 through December 2012 to recipients between 18 and 39 years old with a listed residence in the USA and a specified female gender. It was observed that cases with the SAAE outcomes of gastroenteritis (odds ratio (OR) = 4.6, 95 % confidence interval (CI) = 1.3-18.5), arthritis (OR = 2.5, 95 % CI = 1.4-4.3), systemic lupus erythematosus (OR = 5.3, 95 % CI = 1.5-20.5), vasculitis (OR = 4, 95 % CI = 1.01-16.4), alopecia (OR = 8.3, 95 % CI = 4.5-15.9), or CNS conditions (OR = 1.8, 95 % CI = 1.04-2.9) were significantly more likely than controls to have received HPV4 vaccine (median onset of SAAE symptoms from 6 to 55 days post-HPV4 vaccination). Cases with the outcomes of Guillain-Barre syndrome (OR = 0.75, 95 % CI = 0.42-1.3) or thrombocytopenia (OR = 1.3, 95 % CI = 0.48-3.5) were no more likely than controls to have received HPV4 vaccine. Cases with the general health outcomes of infection (OR = 0.72, 95 % CI = 0.27-1.7), conjunctivitis (OR = 0.88, 95 % CI = 0.29-2.7), or diarrhea (OR = 1.01, 95 % CI = 0.83-1.22) were no more likely than controls to have received HPV4 vaccine. Previous case series of SAAEs and biological plausibility support the observed results. Additional studies should be conducted to further evaluate the potential biological mechanisms involved in HPV4 vaccine-associated SAAEs in animal model systems, and to examine the potential epidemiological relationship between HPV4 vaccine-associated SAAEs in other databases and populations.

The Guillain-Barré syndrome (GBS) occurs after infections and as an adverse reaction to vaccines. No detailed information on incidence rates (IRs) in Germany is available.
This retrospective cohort study estimated age- and sex-specific IRs of GBS in Germany in the years 2007-2009 based on electronic healthcare data from the German Pharmacoepidemiological Research Database (GePaRD). Read More

Two case definitions were applied. GBS cases had a main discharge diagnosis of GBS. GBS_PROCEDURE cases in addition had codes for relevant diagnostic procedures. Crude and standardized IRs (SIRs) with 95% confidence intervals were stratified by year, age group, sex, region and season. IR ratios (IRRs) for each stratification factor were calculated by multivariable Poisson regression.
Among 13,297,678 persons, 889 (693) incident GBS (GBS_PROCEDURE) cases were identified. Overall SIRs per 100,000 person years were 2.4 (2.2-2.5) for GBS and 1.8 (1.7-2.0) for GBS_PROCEDURE. (S)IRs increased with age, peaking in the age group 70-79 years (IR GBS: 5.5 (4.7-6.5)) and were higher in males than in females (e.g., IR GBS: IRR = 1.5 (1.3-1.7)) and in February-April, as compared to the rest of the year. No regional pattern was observed.
(S)IRs of GBS in Germany differed by age, sex and season and were comparable to those found in other studies. RESULTS might be used as a comparator in vaccine safety monitoring. © 2014 S. Karger AG, Basel.

Guillain-Barre syndrome, or acute inflammatory demyelinating polyneuropathy, has been described in the presence of malignancies such as lymphoma. Guillain-Barre syndrome/acute inflammatory demyelinating polyneuropathy causes paresthesias and weakness, which can make the treatment of lymphoma with chemotherapy challenging. Given the rarity of this co-presentation it is not known if the effects of Guillain-Barre syndrome should be considered when selecting a treatment regimen for Hodgkin lymphoma. Read More

To the best of our knowledge, the impact of these treatment modifications has not been previously reported.
We report the case of a 37-year-old Caucasian man with a diagnosis of stage IIB classical Hodgkin lymphoma with concomitant Guillain-Barre syndrome. Our patient originally presented with an enlarged cervical lymph node and quickly developed distal paresthesia and progressive weakness of all four extremities. He was diagnosed with Hodgkin's lymphoma and initiated on treatment with doxorubicin, bleomycin, vinblastine, and dacarbazine. Doses of bleomycin and vinblastine were held or dose-reduced throughout his initial treatment course due to underlying neuropathy and dyspnea. He continued to have persistent disease after five cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine and went on to receive salvage treatments including more chemotherapy, radiation, autologous stem cell transplant and is currently preparing for an allogeneic stem cell transplant.
Paraneoplastic syndromes such as Guillain-Barre syndrome/acute inflammatory demyelinating polyneuropathy can make the treatment of patients with Hodgkin lymphoma more challenging and can interfere with delivering full-dose chemotherapy. Further case series are needed to evaluate the effect that paraneoplastic syndromes, or adjustments made in therapy due to these syndromes, negatively affect the prognosis of patients with Hodgkin lymphoma.

On 5 November 2013, we searched the Cochrane Neuromuscular Disease Group Specialized Register, CENTRAL, MEDLINE, EMBASE, CINAHL Plus, LILACS and AMED. We also searched reference lists of all studies identified for inclusion and relevant reviews, and contacted the authors of included studies and known experts in the field to identify additional published or unpublished data. We also searched trials registries for ongoing studies.
We considered for inclusion randomised controlled trials (RCTs) and quasi-RCTs comparing any form of intervention for fatigue management in adults with peripheral neuropathy with placebo, no intervention or an alternative form of intervention for fatigue. Interventions considered included drugs, pacing and grading of physical activity, general or specific exercise, compensatory strategies such as orthotics, relaxation, counselling, cognitive and educational strategies.
Two review authors independently assessed risk of bias and extracted study data. We contacted study authors for additional information. We collected information on adverse events from the included trials.
The review includes three trials, which were all at low risk of bias, involving 530 people with peripheral neuropathy. The effects of amantadine from one randomised, double-blind, placebo-controlled, cross-over trial comparing amantadine with placebo for the treatment of fatigue in 80 people with Guillain-Barré syndrome (GBS) were uncertain for the proportion of people achieving a favourable outcome six weeks post-intervention (odds ratio (OR) 0.56 (95% confidence interval (CI) 0.22 to 1.35, N = 74, P = 0.16). We assessed the quality of this evidence as low. Two parallel-group randomised double-blind, placebo-controlled trials comparing the effects of two doses of ascorbic acid with placebo for reducing fatigue in adults with Charcot-Marie-Tooth disease type 1A (CMT1A) showed that the effects of ascorbic acid at either dose are probably small (standardised mean difference (SMD) -0.12 (95% CI -0.32 to 0.08, n = 404, P = 0.25)) for change in fatigue after 12 to 24 months (moderate quality evidence). Neither ascorbic acid study measured fatigue at four to 12 weeks, which was our primary outcome measure. No serious adverse events were reported with amantadine. Serious adverse events were reported in the trials of ascorbic acid. However,risk of serious adverse events was similar with ascorbic acid and placebo.
One small imprecise study in people with GBS showed uncertain effects of amantadine on fatigue. In two studies in people with CMT1A there is moderate-quality evidence that ascorbic acid has little meaningful benefit on fatigue. Information about adverse effects was limited, although both treatments appear to be well tolerated and safe in these conditions.There was no evidence available from RCTs to evaluate the effect of other drugs or other interventions for fatigue in either GBS, CMT1A or other causes of peripheral neuropathy. The cost effectiveness of different interventions should also be considered in future randomised clinical trials.
