Asymmetrical weakness associated with central nervous system involvement in a patient with guillain-barrè syndrome

Clinical and Electrophysiological Factors Predicting Prolonged Recovery in Children with Guillain-Barré Syndrome

OBJECTIVE

To compare clinical and nerve conduction studies (NCS) parameters predictive of outcome in children with acute inflammatory demyelinating polyneuropathy (AIDP) and acute motor axonal neuropathy (AMAN).

METHODS

In this prospective observational study, NCS was done on all children at admission and repeated before discharge. Functional status of patients was graded as per Hughes Disability score. These children were followed up till they achieved independent walking. Clinical and NCS criteria were compared between (a) AMAN and AIDP and (b) two subgroups of children with AMAN-those who achieved early (within 60 d) versus delayed (i.e., after 60 d) walking.

RESULTS

Fifty-seven children were initially enrolled, first NCS showed inexcitable nerves in 10, AMAN in 29, acute motor-sensory axonal neuropathy (AMSAN) in 3, AIDP in 13, and 2 were normal. Subsequent NCS showed AMAN in 37, AIDP in 15, AMSAN in 3 patients. There were no deaths, 16 required ventilation. Follow-up till independent walking, was available for 40 patients. AMAN was associated with faster progression, greater peak disability, prolonged hospital stay, and delayed walking (p < 0.05). Asymmetrical nerve involvement predicted prolonged hospital stay as well as delayed walking. In the AMAN group, prolonged ulnar F-wave latencies were significantly associated with delayed walking (p = 0.02).

CONCLUSION

Long term prognosis of pediatric GBS is generally satisfactory. AMAN, asymmetric involvement and prolonged ulnar F-wave latencies in children with AMAN were associated with delayed walking.

Case Report and Literature Analysis: Guillain-Barré Syndrome With Delayed Unilateral Facial Palsy

Guillain-Barré syndrome (GBS) is an acute inflammatory polyradiculoneuropathy in which most patients have cranial nerve involvement, with facial nerve involvement being the most common. However, delayed facial palsy (DFP) with asymmetric facial palsy is a rare manifestation of GBS, and the mechanism is unclear. We report a case of GBS combined with delayed unilateral facial palsy and review previously reported cases of GBS combined with DFP. A total of 28 cases of GBS with DFP, including the case in this report, were included in this study. The occurrence of DFP may be related to early subclinical demyelination of the facial nerve, the blood-nerve barrier of the facial nerve, facial movement, and descending reversible paralysis. The occurrence of unilateral facial palsy may be related to Campylobacter jejuni, specific anti-ganglioside antibodies, and the site of central nervous system anatomical involvement. There is no evidence that immunotherapy is related to the shortening of DFP course and improving patients' prognosis.

Asymmetric Lower Extremity Involvement and Facial Palsy: An Atypical Case of Guillain-Barre Syndrome

Guillain-Barre syndrome (GBS) represents the most common cause of acute flaccid paralysis and is characterized by muscle weakness frequently accompanied by respiratory and bulbar paralysis which oftentimes can be life-threatening. Early recognition and intervention are essential to prevent potential complications and help hasten recovery. Herein, we report a case of a middle-aged female who presented with nonspecific gastrointestinal symptoms that were shortly followed by a unique combination of new-onset facial diplegia and asymmetric lower extremity areflexia. Treatment with intravenous immunoglobulins (IVIG) was initiated following a prompt diagnosis of GBS was made. Clinicians should always be vigilant about the possibility of GBS in the appropriate clinical setting and be aware of the essentials of management of this potentially treatable disease.

Article Commentary: Dysfunction of Corticomotoneurons in Guillain-Barrέ Syndrome (GBS)?

Guillain-Barrέ syndrome (GBS) is characterized by acute and symmetric flaccid paraparesis and areflexia. Involvement of the central nervous system has been infrequently reported. In the current issue of Clinical Medicine: Case reports, an unusual case of GBS with asymmetric muscle weakness was reported. Corticomotoneuronal dysfunction was invoked as a possible cause for this neurological finding. Reversible blockade of voltage gated Na+ channels resulting in conduction failure may be a possible pathophysiological mechanism.
