Adiponectin affects nitric oxide production, and low plasma adiponectin levels are associated with impaired endothelium-dependent vasorelaxation. However, adiponectin pathophysiology in the acute phase after stroke, especially subarachnoid hemorrhage, is not well understood. The present study evaluated the changes in plasma adiponectin concentrations in patients with subarachnoid hemorrhage and investigated the relationship between plasma adiponectin and delayed cerebral ischemia. ⋯ The plasma adiponectin concentrations were significantly lower in patients on days 3 and 7 compared with controls. Plasma adiponectin concentrations in patients with delayed cerebral ischemia were significantly lower than in those without delayed cerebral ischemia on days 3, 7, 10, and 14. The present results indicate that low plasma adiponectin concentrations from day 3 to day 14 might be associated with the development of delayed cerebral ischemia.

Patients with primary central nervous system lymphoma (PCNSL) after treatment with natalizumab have been considered co-incidental. We report another case of PCNSL in a patient where the explosive onset suggests a causal link.
