Juvenile Myasthenia Gravis: An Indian Perspective

Area of Science:

• Pediatric Neurology
• Autoimmune Disorders
• Neuromuscular Junction Diseases

Background:

• Myasthenia Gravis (MG) is an autoimmune neuromuscular junction disorder with pediatric subtypes including juvenile myasthenia gravis (JMG).
• JMG exhibits distinct characteristics compared to adult MG and varies across ethnic groups.
• Limited data exists on JMG prevalence and features specifically within the Indian pediatric population.

Purpose of the Study:

• To investigate the demographic and clinical characteristics of juvenile myasthenia gravis in Indian children.
• To analyze treatment modalities and outcomes for JMG patients in India.
• To address the data gap concerning JMG in India.

Main Methods:

• Retrospective chart analysis of pediatric patients diagnosed with myasthenia from 2005-2015 at a Mumbai tertiary care hospital.
• Inclusion criteria encompassed all diagnosed myasthenia cases in children.
• Data collected included demographics, clinical presentation, investigations, hospital stay, treatment, and outcomes.

Main Results:

• Fifteen children were diagnosed with JMG, presenting as a pre-pubertal cohort (mean age 3.7 years).
• Generalized symptoms were observed in nine patients, while six presented with ocular symptoms.
• A high seropositivity rate of 73% was noted, with treatments involving pyridostigmine, steroids, and immunosuppression; four patients underwent thymectomy.

Conclusions:

• Juvenile myasthenia gravis in Indian children is characterized by severity and high seropositivity.
• Appropriate and timely diagnosis and treatment are crucial for achieving better patient outcomes.
• Thymectomy shows potential in JMG management but warrants further investigation.
