Seasonal distribution of attacks in aquaporin-4 antibody disease and myelin-oligodendrocyte antibody disease.

Background: Seasonal variation in incidence and exacerbations has been reported for neuroinflammatory conditions such as multiple sclerosis and acute disseminated encephalomyelitis (ADEM). It is unknown whether seasonality also influences aquaporin-4 antibody (AQP4-Ab) disease and myelin-oligodendrocyte antibody (MOG-Ab) disease.

Objective: We examined the seasonal distribution of attacks in AQP4-Ab disease and MOG-Ab disease.

Safety profile of an 8F femoral arteriotomy closure using the Angio-Seal device in thrombolysed acute stroke patients undergoing thrombectomy.

Background The relationship between bridging thrombolysis and femoral access site complications after mechanical thrombectomy remains contested. Use of a closure device could minimise bleeding complications. This study aimed to elucidate the rate of access site complications in a cohort of patients treated using an 8F groin sheath with subsequent closure using the Angio-Seal to assess safety and the impact of bridging thrombolysis on access site complication rate.

Human herpes virus-6 encephalitis causing severe anterograde amnesia associated with rituximab, azathioprine and prednisolone combination therapy for dermatomyositis.

Human herpes virus-6 (HHV-6) reactivation is a well-recognised complication following haematological stem cell transplantation, but it is novel in the context of combination immunomodulatory therapy for autoimmune disease. We report a case of severe anterograde amnesia caused by HHV-6 encephalitis in a young female patient on rituximab, azathioprine and prednisolone for dermatomyositis (DM). The use of targeted biologic treatments for systemic autoimmune connective tissue diseases (CTDs) is increasing, particularly when refractory to conventional management.

Plasma complement biomarkers distinguish multiple sclerosis and neuromyelitis optica spectrum disorder.

Background: Multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) are autoimmune inflammatory demyelinating diseases of the central nervous system. Although distinguished by clinicoradiological and demographic features, early manifestations can be similar complicating management. Antibodies against aquaporin-4 support the diagnosis of NMOSD but are negative in some patients.
