Review Case Reports
Autoimmune encephalitis related to LGI1 antibodies with negative MRI study: Description of two cases.
Leucine-rich glioma inactivated 1 (LGI1) antibody-related autoimmune encephalitis is easily misdiagnosed clinically because of its complex and diverse clinical manifestations. We present two cases of LGI1 antibody-related encephalitis with negative imaging findings and perform a literature review on this disease entity. ⋯ Based on our experience and the literature review, we recommend that LGI1 antibody-related encephalitis should be considered when faciobrachial dystonic seizures, acute and subacute-onset seizures, low serum sodium (possibly with low CSF chloride), and cognitive-psychiatric disorders are encountered, even in the absence of specific radiographic and altered CSF findings.

ILD is a common manifestation in pSS and is associated with an increased risk of death. APCA are strongly expressed by hyperplastic alveolar epithelial cells in the fibrotic lung and are associated with an accelerated decline in lung function in IPF. In the present study, we aimed to evaluate the clinical utility of APCA in ILD patients with pSS. ⋯ APCA level is an independent risk factor and might be a potential biomarker for ILD in patients with pSS.
