Aneurysmal subarachnoid hemorrhage (aSAH) is a devastating form of stroke frequently affecting young to middle-aged adults, with an unmet need improve outcome. This special report focusses on the development intrathecal haptoglobin supplementation as treatment by reviewing current knowledge and progress, arriving at Delphi-based global consensus regarding pathophysiological role extracellular hemoglobin research priorities for clinical translation hemoglobin-scavenging therapeutics. After aneurysmal hemorrhage, erythrocyte lysis generates cell-free in cerebrospinal fluid, which strong determinant secondary brain injury long-term Haptoglobin body's first-line defense against binding it irreversibly, preventing translocation into parenchyma nitric oxide-sensitive functional compartments cerebral arteries. In mouse sheep models, intraventricular administration reversed hemoglobin-induced clinical, histological, biochemical features human hemorrhage.

OBJECTIVES: To perform a detailed examination of sodium levels, hyponatremia and fluctuations, their association with delayed cerebral ischemia (DCI) poor outcome after aneurysmal subarachnoid hemorrhage (aSAH). DESIGN: An observational cohort study from prospective SAH Registry. SETTING: Tertiary referral center focused on treatment in the Amsterdam metropolitan area. PATIENTS: A total 964 adult patients confirmed aSAH were included between 2011 2021. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: 277 (29%) developed DCI. Hyponatremia occurred significantly more often DCI compared no-DCI (77% vs. 48%). Sodium hyponatremia, hypernatremia, fluctuations did not predict However, higher levels associated (DCI onset –7, +0, +1, +2, +4, +5, +8, +9 d), (postbleed day 6–10 12–14). Also, hypernatremia greater both patients. CONCLUSIONS: occurrence irrespective presence Therefore, even mild changes warrant close attention.

Subarachnoid hemorrhage is a devastating sequela of aneurysm rupture. Because it disproportionately affects younger patients, the population impact hemorrhagic stroke from subarachnoid substantial. Secondary brain injury significant contributor to morbidity after hemorrhage. Initial causes intracranial pressure elevations, disrupted cerebral perfusion pressure, global ischemia, and systemic dysfunction. These initial events are followed by two characterized timespans secondary injury: early period delayed ischemia period. The identification varying microglial phenotypes across phases paired with functions microglia during each phase provides basis for serving critical role in both promoting attenuating hemorrhage-induced morbidity. duality effects on outcomes following SAH highlighted pleiotropic features these cells. Here, we provide an overview key as cytotoxic restorative effectors. We first describe ontogeny populations that respond then correlate phenotypic development functions, synthesizing experimental data this area.
