Clinical Profile and Outcome of Guillain-Barre Syndrome in Pediatric Patients Admitted to a Tertiary Care Centre: A Retrospective Study.

Aims and Objectives: To study clinical profile and outcome in Pediatric Guillain Barre Syndrome (GBS). Materials and Methods: Retrospective study of 30 patients (age 1 month to 12 years) admitted with GBS enrolled over a period of 2 years (August 2016-July 2018) from Department of Pediatrics of tertiary centre. Results: Mean age was 5.4 years (21 males; 9 females). Most common presenting complaints- symmetrical lower limb weakness (26 cases; 86.67% cases), respiratory complaints (6 cases; 20% cases), quadriparesis (4 cases; 13.33% cases) and facial palsy (2 cases; 6.67%). Antecedent illnesses- gastrointestinal (6 cases) and respiratory (3 cases). Two patients had varicella (in preceding one week) and one had mumps (one month prior to presentation). MRI-spine done in 12 patients; of whom 9 had features of GBS (thickening and contrast enhancement of the intrathecal and cauda equina nerve roots on T1 weighted MRI). Nerve conduction studies done in 16 patients, of which Acute Motor Axonal Neuropathy was seen in 10 cases. Intravenous immunoglobulin was given to 27 patients while 3 received methylprednisolone in addition. 90% patients receiving IVIG showed improvement. Sixteen patients were admitted to the intensive care unit and 7 required mechanical ventilation. Average hospital stay was 13 days. Two patients had recurrent episodes. Common complications included- pneumonia (6 cases; 2 aspiration and 4 ventilator associated) and autonomic disturbances (6 cases). Two patients died due to autonomic disturbances and presence of autonomic disturbances predicted higher mortality (P = 0.034). Conclusions: Gastrointestinal illness was common antecedent illness for GBS. Symmetrical lower limb weakness was commonest complaint. Pneumonia and autonomic disturbances were commonest complications. Presence of autonomic disturbances predicted higher mortality.
