The responses to regular intravenous enzyme infusions were compared in two sibs with Gaucher disease type 2, the acute neuronopathic variant. Enzyme administration was begun at 7 months in patient 1 who had severe progressive visceral and neuronopathic disease. No significant effect of enzyme infusions was noted. Death occurred at 9 months. Patient 2 was prenatally diagnosed and enzyme infusions were initiated at age 4 days. Overall development progressed at a rate similar to her unaffected full sib until her death at 15.1 months. Slowly progressive esotropia, ocular paresis and dysphagia began at 8 months as did infiltrative pulmonary disease. Comparison of these clinical courses show significant visceral and neurologic effects of anticipatory enzyme therapy, but with unaltered outcome, for Gaucher disease type 2.

Neuromuscular junction disorders in children are either genetic, such as congenital myasthenic syndrome, or autoimmune with circulating antibodies most commonly against acetylcholine receptors. There is limited experience recognizing and treating children with myasthenia associated with muscle-specific tyrosine kinase antibodies. We report a seven-year-old child with intermittent esotropia since age 3 months, and two years of progressive and severe diplopia, dysarthria, dysphagia, and facial weakness. Acetylcholine receptor antibodies and genetic testing for congenital myasthenic syndrome were negative. Muscle specific tyrosine kinase antibodies were significantly elevated. Ophthalmoplegia and bulbar weakness were refractory to treatment with acetylcholinesterase inhibitors, corticosteroids and IVIg but completely resolved following treatment with rituximab. Her neurologic examination remained normal at the most recent follow-up, 15 months after initiation of rituximab. Children with MuSK myasthenia, like adults, can respond to rituximab despite long standing disease and failure to improve on other immunosuppressant medications.
