Acute facial diplegia and hyperreflexia: A Guillain-Barre syndrome variant

Hyper-reflexia in Guillain-Barré syndrome: systematic review

Areflexia or hyporeflexia is a mandatory clinical criterion for the diagnosis of Guillain-Barré syndrome (GBS). A systematic review of the literature from 1 January 1993 to 30 August 2019 revealed 44 sufficiently detailed patients with GBS and hyper-reflexia, along with one we describe. 73.3% of patients were from Japan, 6.7% from the USA, 6.7% from India, 4.4% from Italy, 4.4% from Turkey, 2.2% from Switzerland and 2.2% from Slovenia, suggesting a considerable geographical variation. Hyper-reflexia was more frequently associated with antecedent diarrhoea (56%) than upper respiratory tract infection (22.2%) and the electrodiagnosis of acute motor axonal neuropathy (56%) than acute inflammatory demyelinating polyneuropathy (4.4%). Antiganglioside antibodies were positive in 89.7% of patients. Hyper-reflexia was generalised in 90.7% of patients and associated with reflex spread in half; it was present from the early progressive phase in 86.7% and disappeared in a few weeks or persisted until 18 months. Ankle clonus or Babinski signs were rarely reported (6.7%); spasticity never developed. 53.3% of patients could walk unaided at nadir, none needed mechanical ventilation or died. 92.9% of patients with limb weakness were able to walk unaided within 6 months. Electrophysiological studies showed high soleus maximal H-reflex amplitude to maximal compound muscle action potential amplitude ratio, suggestive of spinal motoneuron hyperexcitability, and increased central conduction time, suggestive of corticospinal tract involvement, although a structural damage was never demonstrated by MRI. Hyper-reflexia is not inconsistent with the GBS diagnosis and should not delay treatment. All GBS variants and subtypes can present with hyper-reflexia, and this eventuality should be mentioned in future diagnostic criteria for GBS.

Anti-ganglioside antibodies in Guillain-Barré syndrome and chronic inflammatory demyelinating polyneuropathy in Chinese patients

INTRODUCTION

In this study we investigated the relationships between anti-ganglioside antibodies and Guillain-Barré syndrome (GBS) and chronic inflammatory demyelinating polyneuropathy (CIDP).

METHODS

Samples from 48 Chinese patients diagnosed with GBS and 18 patients diagnosed with CIDP were retrospectively reviewed.

RESULTS

In the GBS patients, 62.5% were classified as having acute inflammatory demyelinating polyneuropathy (AIDP), 27.1% were found to have acute motor axonal neuropathy (AMAN), and 10.4% were unclassified. Serum IgG anti-ganglioside antibodies were detected in 46.2% of the AMAN patients and in 6.7% of the AIDP patients (P < 0.05); 5.6% of the 18 CIDP patients were IgG antibody positive, and 27.8% were IgM antibody positive. Facial palsy and sensory impairment were significantly associated with IgM antibodies.

CONCLUSIONS

These results suggest that IgG anti-GM1 antibodies are associated with AMAN, but not with AIDP, and that IgM antibodies against GM1, GM2, and GM3 are associated with facial nerve palsy. Muscle Nerve 55: 470-475, 2017.

Facial Diplegia with Paresthesia: An Uncommon Variant of Guillain-Barre Syndrome

Facial nerve palsy (FNP) is a common medical problem and can be unilateral or bilateral. Unilateral facial palsy has an incidence of 25 per 100,000 population and most of them are idiopathic. However, facial diplegia or bilateral facial nerve palsy (B-FNP) is rare with an incidence of just 1 per 5,000,000 population and only 20 percent cases are idiopathic. Facial diplegia is said to be simultaneous if the other side is affected within 30 days of involvement of first side. Guillain-Barre Syndrome (GBS) is a common cause of facial diplegia and almost half of these patients have facial nerve involvement during their illness. Facial Diplegia with Paresthesias (FDP) is a rare localized variant of GBS which is characterized by simultaneous facial diplegia, distal paresthesias and minimal or no motor weakness. We had a patient who presented with simultaneous weakness of bilateral facial nerve and paresthesias. A diagnosis of GBS was made after diligent clinical examination and relevant investigations. Patient responded to IVIG therapy and symptoms resolved within two weeks of therapy.

When is facial diplegia regarded as a variant of Guillain-Barré syndrome?

A variant of Guillain-Barré syndrome (GBS) with predominant manifestation of facial diplegia (FD) has been described recently. This study aimed to characterize and determine the incidence of this FD-predominant GBS variant. The clinical and serological information of 900 consecutive patients were reviewed. In total, eight patients were identified between January 2007 and December 2010 as having FD accompanied by some features of GBS. These features were subjective sensory symptoms such as distal paresthesia (7/8, 88%), albumin-cytological (A/C) dissociation (7/8, 88%), antecedent infection (6/8, 75%), and minor nerve conduction study (NCS) abnormalities (5/7, 71%). One patient presented with the typical NCS feature of demyelinating neuropathy. Only two patients exhibited areflexia (2/8, 25%). None of the patients possessed any anti-ganglioside antibodies; however, the serum of two patients was positive for anti-mycoplasma antibody (2/6, 33%). FD variant of GBS occurred in less than 1% of our dataset. FD can be a regional variant of GBS when it is accompanied by supporting features, such as subjective tingling, A/C dissociation, and minor NCS abnormalities.

Rare encounter of unilateral facial nerve palsy in an adolescent with Guillain-Barré syndrome

Unilateral facial nerve palsy is rarely encountered in Guillain-Barré syndrome (GBS). We report a case of an adolescent girl who presented with peripheral ascending weakness, preceded by Campylobacter jejuni infection. After treatment with intravenous immunoglobulin, the peripheral weakness improved. Electro-diagnostic testing confirmed axonal dysfunction and the patient was positive for antiganglioside antibodies. However, the patient developed unilateral left-sided facial weakness. She was managed with further intravenous immunoglobulin and intensive physiotherapy. The outcome for facial palsy was very good, with almost complete resolution after 2 weeks.

Isolated facial diplegia in Guillain-Barré syndrome: Bifacial weakness with paresthesias

Bifacial weakness with paresthesias (BFP) is a subtype of Guillain-Barré syndrome defined by rapidly progressive bilateral facial weakness in the absence of other cranial neuropathies, ataxia, or limb weakness. Many patients also complain of distal limb paresthesias and display diminished or absent deep tendon reflexes. BFP is a localized form of Guillain-Barré syndrome and is thought to be caused exclusively by demyelinating- rather than axonal-type neuropathy. Patients with BFP do not display anti-ganglioside IgG antibodies. Since it is rare, many physicians are unfamiliar with BFP, as bilateral facial weakness is more commonly associated with sarcoidosis, Lyme disease, or meningeal pathology. Many patients diagnosed with bilateral Bell palsy may instead have BFP. In this review, we highlight the clinical features of BFP and outline diagnostic criteria.

Antibodies to single glycolipids and glycolipid complexes in Guillain-Barré syndrome subtypes

OBJECTIVE

To comprehensively investigate the relationship between antibodies to single glycolipids and their complexes and Guillain-Barré syndrome subtypes and clinical features.

METHODS

In acute sera from 199 patients with Guillain-Barré syndrome, immunoglobulin G (IgG) antibodies to glycolipids and ganglioside complexes were tested using ELISA against individual antigens from single glycolipids including gangliosides (LM1, GM1, GM1b, GD1a, GalNAc-GD1a, GD1b, GT1a, GT1b, GQ1b) and a neutral glycolipid, asialo-GM1 (GA1), and antigens from the combination of 2 different glycolipids. Based on serial nerve conduction studies, the electrodiagnoses were as follows: 69 demyelinating subtype, 85 axonal subtypes, and 45 unclassified.

RESULTS

Significant associations were detected between acute motor axonal neuropathy subtype and IgG antibodies to GM1, GalNAc-GD1a, GA1, or LM1/GA1 complex. Reversible conduction failure was significantly associated with IgG antibodies to GM1, GalNAc-GD1a, GD1b, or complex of LM1/GA1. No significant association was demonstrated between acute inflammatory demyelinating polyneuropathy and any of the glycolipids or ganglioside complexes. Anti-ganglioside complex antibodies alone were detected in 7 patients (5 axonal subtype).

CONCLUSIONS

The current study demonstrates that antibodies to single glycolipids and ganglioside complexes are associated with acute motor axonal neuropathy or acute motor conduction block neuropathy but not acute inflammatory demyelinating polyneuropathy.

CLASSIFICATION OF EVIDENCE

This study provides Class II evidence that antibodies to glycolipids are increased in patients with acute motor axonal neuropathy and acute motor conduction block neuropathy but not acute inflammatory demyelinating polyneuropathy.

Acute small fiber neuropathy following Mycoplasma infection: a rare variant of Guillain-Barré syndrome

Guillain-Barré syndrome (GBS) is a well-described condition involving the peripheral nervous system. The most well-known form of this disease is acute inflammatory demyelinating polyradiculoneuropathy. Among the different variants of GBS described in the literature, the sensory variant is scantily recognized. There has been a recent attempt to classify the sensory variants of the GBS and bring more objectivity to this diagnostic paradigm. We report a rare sensory variant of GBS presenting with isolated small nerve fiber involvement peripherally in the limbs and associated facial nerve palsy in a patient who had clinical and serological evidence of a preceding Mycoplasma pneumoniae infection. The symptoms resolved gradually with intravenous immunoglobulin therapy. This case adds to the growing literature of the rare form of acute small fiber neuropathy and GBS variants.

Two unusual variants of Guillain-Barre syndrome

Guillain-Barre syndrome (GBS) is a group of autoimmune diseases characterised by acute, acquired and immune-mediated polyneuroradiculopathy. A large number of clinical subtypes of GBS have been described over last 100 years since the first description of this syndrome. We report two such cases GBS variants--first, AMAN with brisk reflexes and second being acute motor axonal neuropathy with conduction block. Through this case report, we intend to make the treating physicians and neurologist aware of these rare variants so that such cases would be appropriately diagnosed and treated.

Guillain-Barre syndrome with hyperreflexia: A variant

Guillain-Barre syndrome (GBS) is a common cause of acute peripheral neuropathy and is characterized by hyporeflexia or areflexia. Hyperreflexia has been rarely reported with acute motor axonal neuropathy. A 10-year-old boy presented with asymmetrical weakness of upper and lower limbs and change of voice. Weakness progressed in the hospital with involvement of multiple cranial nerves, preserved deep tendon jerks with extensor plantar, and normal abdominal reflexes. He was treated with IV immunoglobulin and IV methylprednisolone. He was able to walk with support with normal voice at the time of discharge. GBS should be a differential diagnosis in patients with acute quadriparesis even if there are preserved deep tendon reflexes.

[Diagnosis of immune-mediated neuropathies]

Separate discussion of immune-mediated neuropathies from other neuropathies is justified by the serious consequences of the natural course of these diseases, like disability and sometimes even life threatening conditions. On the other hand nowadays effective treatments already exist, and with timely and correct diagnosis an appropriately chosen treatment may result in significant improvement of quality of life, occasionally even complete recovery. These are rare diseases, and the increasing number of different variants makes it more difficult to recognize them. Their diagnosis is based on the precise knowledge of clinical signs and symptoms, and it is verified by the help of neurophysiologic and laboratory, first of all CSF examinations. Description of clinical features of the classic acute immune-mediated neuropathy, characterized by ascending paresis and demyelination is followed by a summary of characteristics of newly recognized axonal, regional and functional variants. Chronic immune-mediated demyelinating polyneuropathies are not diagnosed in due number even today. This paper does not only present the classic form but it also introduces the ever increasing special variants, like distal acquired demyelinating sensory neuropathy, Lewis-Sumner syndrome, multifocal motor neuropathy and paraproteinemic neuropathies. Vasculitic neuropathies can be divided into two groups: systemic and non-systemic ones. The first sign of a vasculitic neuropathy is a progressive, painful mononeuropathy; the classic clinical presentation is the mononeuritis multiplex. It is characterized by general signs like fever, loss of weight, fatigue. In systemic vasculitis organ specific symptoms are also present. From the paraneoplastic diseases the subacute sensory neuropathy and the sensory neuronopathy are members of the immune-mediated neuropathies, being most frequently associated with small cell lung cancer.

Hyperreflexic Guillain-Barré syndrome

Guillain-Barré syndrome (GBS) is an acquired acute autoimmune polyradiculoneuropathy. The 2 features considered essential for the diagnosis of GBS are progressive motor weakness and areflexia. There have been several descriptions of reflex preservation and hyperreflexia in axonal variant of GBS in Chinese, Japanese, and European populations but it is not common in the Indian subcontinent. We report 2 such cases discussing the pathophysiology and management aspects. This case report is to impress upon treating physicians and neurologists in training that a hyperreflexic variant of GBS albeit rare, should not be missed in a given clinical setting.

Long term clinical and electrophysiological assessment of Croatian children with corticospinal tract involvement in Guillain-Barré syndrome (GBS)

Guillain-Barré syndrome (GBS) is characterized by areflexia. Hyperreflexia is reported in acute motor axonal neuropathy (AMAN). We present 16 children with GBS at the age of 14 months to 13 years. All children studied fulfilled accepted diagnostic criteria for GBS. Hyperreflexia or positive Babinski sign were obtained in all children studied during follow up. Brain and spinal cord MR scans did not reveal any significant structural and morphological abnormalities of central nervous system. The children were examined clinically and electromyoneurographically 2-5 times successively during 1-8.5 years of follow-up. According to established electrodiagnostic criteria demyelinating form of GBS was most common (68%) compared to axonal (18,7%) or mixed form (12,5%). No children had antecendent Campylobacter jejuni infection. Antiganglioside antibodies were detected in 18,7% of patients associated with demyelinating or mixed (axonal/demyelinating) form. Time to nadir and recovery period of walking ability is prolonged more often in demyelinating GBS. Clinical improvement occur earlier compared to improvement of abnormal electrophysiological parameters.Outcome was excellent in 11 in the period 1 month-8.5 years. Hyperreflexia usually appeared in recovery period suggesting involvement of upper motor neurons or spinal interneurons occurring in Croatian children with both demyelinating and axonal form of GBS usually associated with milder course of disease.

Guillain-Barré syndrome following H1N1 immunization in a pediatric patient

OBJECTIVE

To report a case of Guillain-Barré syndrome (GBS) following a dose of influenza A (H1N1) vaccine (Arepanrix).

CASE SUMMARY

An 11-year-old boy was admitted to the hospital after presenting with facial diplegia; abdominal, forehead, and thigh pain; and acute cervical pain. He had received the Arepanrix H1N1 subcutaneous vaccine 13 days before symptom onset. The neurologic examination also revealed a symmetric bilateral paralysis of the VIIth cranial nerve and intense pain, proximal weakness of the shoulder girdles and pelvis, and preserved deep tendon reflexes. Cerebrospinal fluid analysis revealed an albuminocytologic dissociation. Therefore, a diagnosis of atypical GBS following vaccination against HINI influenza was made.

DISCUSSION

Based on the clinical evaluation, laboratory test results, neurologic features, and the exclusion of alternative diagnoses, the Naranjo probability scale revealed a probable relationship between the clinical manifestations of GBS and the vaccine against influenza A (H1N1) received by the patient. This is the first published case for the 2009 influenza pandemic in children.

CONCLUSIONS

While recent studies have found inconclusive results on the association between influenza vaccine and GBS, all suspected cases should be published for further evaluation.

Enteritis caused by Campylobacter jejuni followed by acute motor axonal neuropathy: a case report

Introduction

Campylobacter species represent the main cause of bacterial diarrhea in developed countries and one of the most frequent causes of enterocolitis in developing ones. In some patients, Campylobacter jejuni infection of the gastrointestinal tract has been observed as an antecedent illness of acute motor axonal neuropathy, a variant of Guillain-Barré syndrome.

Case presentation

We present a case of acute motor axonal neuropathy following infection with Campylobacter jejuni subspecies jejuni, biotype II, heat stable serotype O:19. A 46-year-old Caucasian man developed acute motor neuropathy 10 days after mild intestinal infection. The proximal and distal muscle weakness of his upper and lower extremities was associated with serum antibodies to Campylobacter jejuni and antibodies to ganglioside GM1. The electromyographic signs of neuropathic muscle action potentials with almost normal nerve conduction velocities indicated axonal neuropathy. Our patient's clinical and electrophysiological features fulfilled criteria for the diagnosis of an acute motor axonal neuropathy, a subtype of Guillain-Barré syndrome.

Conclusion

As this is the first case of acute motor axonal neuropathy following infection with Campylobacter jejuni subspecies jejuni reported from the Balkan area, the present findings indicate the need for systematic studies and further clinical, epidemiological and microbiological investigations on the prevalence of Campylobacter jejuni and its heat stable serotypes in the etiology of Guillain-Barré syndrome and other post-infectious sequelae.

External and internal ophthalmoplegia, facial diplegia, ataxia and exaggerated deep tendon reflexes associated with anti-GQ1b antibodies: A new variant of acute ophthalmoparesis

We present the case report of a patient with antibodies to ganglioside GQ1b, who presented with pupillary areflexia, external ophthalmoplegia, ataxia, brisk deep tendon reflexes and facial muscle diplegia following a viral illness. The patient was diagnosed with acute ophthalmoparesis, which is a rare variant of Miller Fisher syndrome that has been characterised recently. We describe a unique presentation of this rare condition, and consider the range of presentations that can occur in association with antibodies to the GQ1b ganglioside.

Clinical and electromyographic deep tendon reflexes in polyneuropathy: diagnostic value and prevalence*

BACKGROUND

Evidence is accumulating that patients with polyneuropathy may present with normal clinical deep tendon reflexes (C-DTR). There are few studies that assessed the diagnostic utility of electromyographically recorded DTR (Er-DTR) in patients with polyneuropathy.

OBJECTIVES

The objectives of this study were twofold: (i) to evaluate the prevalence of preserved C-DTR in polyneuropathy; (ii) diagnostic value of Er-DTR latency measurement in patients with polyneuropathy.

METHODS

We prospectively studied 38 controls and 185 patients with polyneuropathy. All subjects had evaluation of C-DTR, Er-DTR obtained from right biceps brachii (BR), right patellar (PR) and bilateral ankle reflexes (AR).

RESULTS

Of these 185 patients, 118 (63.8%) had chronic axonal neuropathy (CAN), 49 (26.5%) demyelinating polyradiculoneuropathy (DPN) and 18 (9.7%) small fiber neuropathy (SFN). The C-DTR were normal in 65 patients whereas 39 of these 65 (60%) patients had abnormalities of Er-DTR at one or more sites. Er-DTR latencies in patients with polyneuropathies were prolonged at all sites compared with controls (P < 0.01). Among patients with various types of polyneuropathies the Er-DTR, mean latencies at all the sites and latency indicative of demyelination (>150% of the normal mean) were higher in patients with DPN than that of CAN or SFN (P < 0.01).

CONCLUSIONS

We conclude that C-DTR are preserved in 35.1% of the patients with polyneuropathies and Er-DTR should be performed in such patients in order to provide electrophysiological evidence of a polyneuropathy. Er-DTR are useful in distinguishing axonal from demyelinating disorders of peripheral nerve, and detection of subclinical involvement of large fibers in SFN.

Facial diplegia with hyperreflexia--a mild Guillain-Barre Syndrome variant, to treat or not to treat?

Guillain Barre Syndrome (GBS) is readily diagnosed when the presentation is that of ascending weakness and areflexia. Atypical presentations with preserved, and at times, brisk reflexes, can be a diagnostic dilemma. We describe a patient with GBS who presented with facial diplegia and hyperreflexia on examination and discuss management options.

Guillain-Barré syndrome and its treatment

Guillain-Barré syndrome typically presents with an acute ascending areflexic weakness, progressing over 4 weeks or less. The most common form of the disease is an acute inflammatory demyelinating polyneuropathy, but other forms with primarily axonal pathologies are well documented. The association of Guillain-Barré syndrome with a range of antecedent infections, particularly Campylobacter jejuni enteritis, is also established. A range of serological and neurophysiological investigations can assist in making an accurate diagnosis. Background information about the syndrome and the evidence base for such treatments are discussed herein.
