Lisocabtagene maraleucel, sold under the brand name Breyanzi, is a cell-based gene therapy used to treat large B-cell lymphoma.Side effects include hypersensitivity reactions, serious infections, low blood cell counts, and a weakened immune system. The most common side effects include decreases in neutrophils (a type of white blood cell that fights infections), in red blood cells or in blood platelets (components that help the blood to clot), as well as cytokine release syndrome (a potentially life-threatening condition that can cause fever, vomiting, shortness of breath, pain and low blood pressure) and tiredness.Lisocabtagene maraleucel, a chimeric antigen receptor (CAR) T cell (CAR-T) therapy, is the third gene therapy approved by the U.S. Food and Drug Administration (FDA) for certain types of non-Hodgkin lymphoma, including diffuse large B-cell lymphoma (DLBCL). Lisocabtagene maraleucel was approved for medical use in the United States in February 2021.
Over elapsed months and years, the hallucinations may become more or less frequent with changes in ability to see. The length of time that the sight impaired person can have these hallucinations varies according to the underlying speed of eye deterioration. A differential diagnosis are ophthalmopathic hallucinations. Focal epilepsy
Visual hallucinations due to focal seizures differ depending on the region of the brain where the seizure occurs. For example, visual hallucinations during occipital lobe seizures are typically visions of brightly colored, geometric shapes that may move across the visual field, multiply, or form concentric rings and generally persist from a few seconds to a few minutes. They are usually unilateral and localized to one part of the visual field on the contralateral side of the seizure focus, typically the temporal field. However, unilateral visions moving horizontally across the visual field begin on the contralateral side and move toward the ipsilateral side.Temporal lobe seizures, on the other hand, can produce complex visual hallucinations of people, scenes, animals, and more as well as distortions of visual perception. Complex hallucinations may appear to be real or unreal, may or may not be distorted with respect to size, and may seem disturbing or affable, among other variables. One rare but notable type of hallucination is heautoscopy, a hallucination of a mirror image of ones self. These "other selves" may be perfectly still or performing complex tasks, may be an image of a younger self or the present self, and tend to be briefly present.
