ABSTRACT
Adenylate kinase 5 (AK5) antibodies are biomarkers of a poorly responsive to immunotherapy, non-paraneoplastic, autoimmune limbic encephalitis. We detected 6 patients (all female, median age 72 years [49-80]) with identical CSF antibody staining by indirect immunofluorescence on mouse tissues. We identified AK5 as the antigen and confirmed with standardized assays. Three patients with clinical information had limbic encephalitis, inflammatory CSF and mesiotemporal lobe T2 hyperintensities that evolved to atrophy on brain MRI. One patient had burning smell sensation with no evidence of seizures. Despite immunotherapy, minimal improvement was noticed in one patient; all had severe memory deficits remaining.
