Case presentation: A 55-year-old Caucasian woman with Human immunodeficiency virus infection, diag- nosed with Guillain Barre syndrome was studied. Serum and CSF immunoglobulin G and Albumin levels were quantified by using an immunodiffusion technique. She had preceding viral symptoms. The clinical diagnosis of the illness in this patient was pa-resthesias or sensory loss, tendon reflexes. It was also observed cranial nerves abnormalities, acute mo- tor and sensory axonal neuropathy and ophthalmoplegia. The mean CD4 count was 367/mm3, CSF white blood cell 25 wbc/mm3. The serum sodium concentration was significantly low (133 mmol/L). She had a respiratory compromise as a result of their neuropa- thy and developed congestive heart failure and hy- potension and died of a cardiac arrest. The neuro-immunological response described by our patient was a blood/CSF barrier dysfunction without IgG intra-thecal synthesis. Conclusion: There is no doubt that this study is of great importance because will help clinicians increase their knowledge of the immune response in patients with this autoimmune disorder on the basis of this case report, in which, for first time, could be seen the neuroimmunological response through the reibergram in a patient with HIV- asso-ciated Guillain-Barre syndrome.展开更多

Given its broad clinical spectrum and extremely complex pathogenesis, as well as difficulties in its early diagnosis and treatment, anti-IgLON5 disease has become the subject of considerable research attention in the field of neuroimmunology. Anti-IgLON5 disease has characteristics of both autoimmunity and neurodegeneration due to the unique activity of the antiIgLON5 antibody. Neuropathologic examination revealed the presence of a tauopathy preferentially affecting the hypothalamus and brainstem tegmentum, potentially broadening our understanding of tauopathies. In contrast to that seen with other autoimmune encephalitis-related antibodies, basic studies have demonstrated that IgLON5 antibody-induced neuronal damage and degeneration are irreversible, indicative of a potential link between autoimmunity and neurodegeneration in antiIgLON5 disease. Herein, we comprehensively review and discuss basic and clinical studies relating to anti-IgLON5 disease to better understand this complicated disorder.展开更多
