Objective: To establish the prognostic significance of a biomarker of excitotoxic brain damage (antibodies to the NR2 subunit of the N-methyl-D-aspartate (NMDA) glutamate receptor) as a predictor of damage to the central nervous system (CNS) in preterm infants.
Material And Methods: 24 newborns with a gestational age of 24-33 weeks were examined with the determination of the level of antibodies to the NR2 subunit of the NMDA glutamate receptor on the 21st day of life.
Results: In the course of the study, it was found that the level of antibodies to the NR2 subunit of the NMDA glutamate receptor on the 21st day of life, in combination with the level of cord blood lactate and the resistance of cerebral vessels on the 1st day of life, can be predictors of CNS damage in a premature baby at the age of 1 month of corrected age. Predictors of an unfavorable neurological outcome at the age of 1 year of corrected age in a premature baby with perinatal CNS damage are the level of cord blood lactate and antibodies to the NR2 subunit of the NMDA glutamate receptor, determined on the 21st day of life in a newborn.
Conclusion: The biomarker of excitotoxic brain damage can be a predictor of long-term neurological outcome and determine the amount, type and duration of neuroprotective care for premature infants.

Article Synopsis
- The study aimed to investigate the role of immunological markers in patients with obstructive sleep apnea (OSA) and accompanying health issues by comparing two groups: one with OSA and one without.
- Results showed higher levels of certain markers (GFAP, BDNF, antibodies to acetylcholine receptors) and indicators of depression and drowsiness in OSA patients, suggesting cognitive impairments linked to these markers.
- The findings indicate that neuromarkers like GFAP and BDNF are associated with cognitive dysfunction in OSA, with elevated acetylcholine receptor antibodies possibly pointing to neuromuscular issues and emotional problems, particularly depression and fatigue, worsening as OSA severity increases.

Presented clinical observation of anti-NMDA-receptor encephalitis, which was first described in 2007, is rare and to date has not been sufficiently studied. The disease often manifests with psychopathological symptoms and catatonia, so patients are transferred into a mental healthcare institution and often require intensive care and resuscitation, due to the development of life-threatening respiratory and hemodynamic disorders. Diagnosis is based on detection of autoantibodies to the NR1- and NR2 subunits of the glutamate NMDA receptor in blood serum and cerebrospinal fluid.

Widely distributed in the central nervous system (CNS), N-methyl-D-aspartate receptors (NMDARs) are believed to be involved in long-term potentiation, essential in regulating and forming memory. This condition primarily occurs in young females because of autoantibodies forming against the N-methyl-D-aspartate receptor-1 (NR1) or N-methyl-D-aspartate receptor-2 (NR2) subunits of NMDAR in the CNS, ultimately portraying a unique psychoneurological phenomenon. Patients with antibodies against NMDAR present with a combination of neurological and psychiatric signs and symptoms.

Anti-N-methyl-D-aspartate receptor (NMDAr) encephalitis is a prevalent autoimmune condition marked by diverse neuropsychiatric symptoms, primarily impacting young females. The exact mechanisms underlying the development of NMDAr encephalitis have not been fully elucidated. Nonetheless, studies have demonstrated that auto-antibodies targeting the NR1-NR2 subunits of the NMDAr can trigger receptor dysfunction within the central nervous system, thus giving rise to the associated symptoms.
