Autoimmune-induced glutamatergic receptor dysfunction methods and treatments
View Patent ↗This invention provides a method of enhancing NMDAR-mediated neurotransmission in a disease associated with NMDAR antibody production, said method comprising administering an NMDAR agonist, an alanine-serine-cysteine transporter inhibitor, a D-amino acid oxidase inhibitor, a glycine transport inhibitor or a combination thereof to said subject. This invention also provides a method of mitigating the severity of, mitigating the pathogenesis of, lowering the incidence of or treating a disease associated with NMDAR antibody production, said method comprising administering an agent, which is an NMDAR agonist, an alanine-serine-cysteine transporter inhibitor, a D-amino acid oxidase inhibitor, a glycine transport inhibitor or a combination thereof to said subject.
1. A method for treating anti-NMDAR encephalitis, comprising:
administering to a patient having an autoimmune encephalitis associated with antibodies against synaptic N-methyl-D-aspartate receptor (NMDAR), a therapeutically effective amount of D-serine.
2. The method of claim 1 , wherein said encephalitis is associated with occult tumor.
3. The method of claim 2 , wherein said tumor is an ovarian teratoma.
4. The method of claim 2 , wherein said method further comprises the step Of removing said tumor, providing immunotherapy or a combination thereof.
5. The method of claim 1 , further comprising administration of glycine (GLY), additional D-serine, D-cycloserine (DSR), or a combination thereof.
6. The method of claim 1 , wherein D-serine is administered at a dosage of 30-60 mg/kg/d.
7. The method of claim 5 , wherein glycine is administered at a dosage of 40-60 g/d.
8. The method of claim 5 , wherein D-cycloserine is administered at a dosage of 250-1000 mg/d.
9. The method of claim 1 , which is utilized during an acute stage of a disease associated with NMDAR antibody production.
10. The method of claim 1 , which is utilized during a rehabilitational stage of a disease associated with NMDAR antibody production.
11. The method of claim 1 , further comprising administration of an agent selected from the group consisting of alanine-serine-cysteine transporter inhibitor, a D-amino acid oxidase inhibitor, a glycine transport inhibitor or a combination thereof.
