Clinical manifestations of the anti-IgLON5 disease
2017
Objective:To report the presentation, main syndromes, human leukocyte antigen (HLA) association, and immunoglobulin G (IgG) subclass in the anti-IgLON5 disease: a disorder with parasomnias, sleep apnea, and IgLON5 antibodies.Methods:This was a retrospective clinical analysis of 22 patients. The IgG subclass was determined using reported techniques.Results:Patients' median age was 64 years (range 46–83). Symptoms that led to initial consultation included sleep problems (8 patients; 36%), gait abnormalities (8; 36%), bulbar dysfunction (3; 14%), chorea (2; 9%), and cognitive decline (1; 5%). By the time of diagnosis of the disorder, 4 syndromes were identified: (1) a sleep disorder with paras…
Loss of striatal histamine H2receptors in Huntington's: Chorea but not in Parkinson's disease: Comparison with animal models
1993
Autoradiographic techniques were used to study the distribution of histamine H2-receptors as labeled with [125I]iodoaminopotentidine in the brains of patients affected by human neurodegenerative pathologies, as compared with control cases. The highest levels of histamine H2 binding sites in control cases were found in the caudate, putamen, and accumbens nuclei. In Huntington's chorea, the levels of histamine H2 receptor binding sites were found to be markedly decreased in virtually all regions examined, particularly in the putamen and globus pallidus lateralis. The loss of binding sites was related to the grade of the disease. Losses were more marked in grade III disease cases. The possible…
