The objective of this study was to determine the level of antibodies against nerve growth factor in the serum, activity of elastase in leukocytes and concentration of its inhibitor in patients with sensorineural loss of hearing of different severity, and degree of progression. It was shown that patients with the rapidly developing form of the disease have lower titers of antibodies against nerve growth factor compared with their normal values and an unfavourable ratio of activities of leukocytic elastase and its inhibitor. The patients were divided into three groups based on the level of antibodies against nerve growth factor. They were found to differ in terms of the state of the system of proteolytic enzymes in blood.

Background: Neuroinflammation is a critical factor of Alzheimer's Disease (AD). Dysregulation of complement leads to excessive inflammation, direct damage to self-cells and propagation of injury. This is likely of particular relevance in the brain where inflammation is poorly tolerated and brain cells are vulnerable to direct damage by complement.

Isolated ophthalmoplegia as an anti-glutamic acid decarboxylase 65 (anti-GAD65) antibody-associated neurological syndrome is rare. We present a case of a 22-year-old pregnant Hispanic female patient who presented initially with a left oculomotor nerve palsy following an emergency department (ED) visit for migraine headache. Brain imaging was done with no important findings.

Neuromyelitis optica spectrum disorder (NMOSD) includes conditions with autoimmune genesis, which are manifested by attacks of optic neuritis (ON) and transverse myelitis (TM), and also express aquaporin 4 (NMO-IgG) or myelin oligo-endocytic glycoprotein (MOGAb) antibodies. In rare cases, the disease may also have a clinical presentation with only TM, without ON or with ON, without TM. These conditions are also included in the spectrum.

Frozen tissue sectioning comes with inherent inescapable limitations, including cryosectioning artifact and limited sample shelf-life. However, a parallel approach to identify NMJs in paraffin-embedded tissue sections has not been previously described.

Brentuximab-vedotin (BV)-induced neurotoxicity (BVIN), a frequent adverse event caused by this monoclonal antibody, is the primary reason for dose modification or drug discontinuation, and is characterized by sensory, motor, and/or autonomic peripheral nerve dysfunctions. Although reversible, BVIN can persist for months or years after treatment and negatively affect quality of life (QoL). Currently, BVIN is managed by dose adjustment or drug interruption, leading to an increased risk of disease relapse.
