Abstract:
An 11 year old male presented with headache, vomiting and weakness of right side of body. One day after admission he developed right focal seizures. He had 5 previous episodes of stroke, the first at 11 months age. His milestones were normal upto the first episode but subsequent mile stones were delayed. His serum and CSF lactic acids were raised. Muscle biopsy showed ragged red fibres on modified Gomori-trichrome staining. His EEG, CT scan and MRI were normal this time. The child improved spontaneously after 7 days. His recovery time progressively became shorter with each episode of stroke. Maximum time for recovery was noted during first episode and least in current episode. This is the first report of Melas syndrome in Indian literature.
Insights
This case study highlights MELAS syndrome, a mitochondrial disease, in an 11-year-old Indian boy experiencing recurrent strokes and developmental delays. Early diagnosis and management are crucial for mitochondrial disorders.
Area of Science:
- Neurology
- Genetics
- Pediatrics
Background:
- Mitochondrial myopathy, lactic acidosis, and stroke-like episodes (MELAS) syndrome is a rare genetic disorder.
- It typically presents in childhood with neurological and muscular symptoms.
Observation:
- An 11-year-old male presented with stroke-like symptoms including headache, vomiting, right-sided weakness, and focal seizures.
- He had a history of five previous stroke episodes since infancy, with progressive developmental delays.
- Elevated serum and CSF lactic acid levels and ragged red fibers on muscle biopsy confirmed mitochondrial dysfunction.
Findings:
- Despite normal EEG, CT, and MRI during the current episode, the patient showed spontaneous recovery within 7 days.
- Recovery time shortened with each successive stroke episode, indicating a potential adaptive response or disease progression pattern.
- This case represents the first documented instance of MELAS syndrome in the Indian population.
Implications:
- This case underscores the importance of considering MELAS syndrome in pediatric patients with recurrent stroke-like episodes and mitochondrial dysfunction.
- The unique recovery pattern observed warrants further investigation into the pathophysiology and potential therapeutic strategies for MELAS syndrome.
- Increased awareness and reporting of MELAS syndrome in diverse populations like India are crucial for improving diagnosis and patient care.
