Abstract :
OBJECTIVES: MEGDHEL [3-methylglutaconic aciduria (MEG), deafness (D), hepatopathy (H), encephalopathy (E), and Leigh-like disease (L)] syndrome is an autosomal recessive disorder caused by mutations in the serine active site-containing protein 1 (SERAC1) gene. MEGDHEL syndrome is clinically characterized by sensorineural hearing loss, encephalopathy, hepatopathy, 3-methylglutaconic aciduria, and Leigh-like lesions on cranial magnetic resonance imaging. During the neonatal period, it has been reported to present with hypoglycemia, hyperammonemia, impaired liver functions, cholestasis, metabolic acidosis, and sepsis-like clinical findings. However, clinical findings in the neonatal period were reported as a result of the retrospective evaluation of patients diagnosed at an older age. Herein we reported two cases diagnosed as MEGDHEL syndrome during neonatal period in two different clinics with sepsis-like findings, impaired liver functions, and ammonia levels high enough to require dialysis. CASE PRESENTATION: One of the cases was born 37 weeks of gestation with a birth weight of 2,060 g and initially presented with respiratory distress and feeding difficulties. The other case admitted to the neonatal intensive care unit had fed problems together with respiratory distress and circulatory failure within the first 24 h after initiation of parenteral nutrition. CONCLUSIONS: MEGDHEL syndrome should be suspected in patients with sepsis-like clinical features and hyperammonemia. |
