Summary
Preventive moxifloxacin therapy reduced post-stroke infections in patients with severe ischemic stroke. This study highlights the role of immunodepression in infection development after stroke.
Area of Science:
- Neurology
- Infectious Diseases
- Clinical Trials
Background:
- Pneumonia is a significant cause of mortality following acute stroke.
- Mouse models show moxifloxacin reduces post-stroke infections, mortality, and improves neurological outcomes.
- This study evaluates moxifloxacin's efficacy in human stroke patients.
Purpose of the Study:
- To investigate the effectiveness of preventive antibacterial therapy with moxifloxacin in patients with acute ischemic stroke.
- To assess the impact of moxifloxacin on infection rates, neurological outcomes, and survival.
- To explore the role of stroke-induced immunodepression and bacterial resistance.
Main Methods:
- The Preventive ANtibacterial THERapy in acute Ischemic Stroke (PANTHERIS) trial was a randomized, double-blind, placebo-controlled study.
- 80 patients with severe, non-lacunar, ischemic stroke (NIHSS>11) in the MCA territory were enrolled.
- Patients received intravenous moxifloxacin (400 mg daily) or placebo for 5 days, starting within 36 hours of stroke onset.
Main Results:
- Intention-to-treat analysis showed a trend towards reduced infection rates with moxifloxacin (15.4% vs. 32.5%, p=0.114).
- Per-protocol analysis revealed a significant reduction in infection rates (17.1% vs. 41.9%, p=0.032) with moxifloxacin.
- Moxifloxacin did not significantly influence neurological outcome or survival; fluoroquinolone resistance rates were similar between groups.
- Treatment arm and monocytic HLA-DR expression predicted post-stroke infections.
Conclusions:
- Preventive moxifloxacin administration appears superior to placebo in reducing infections after severe non-lacunar ischemic stroke.
- The study underscores the critical role of immunodepression in the development of post-stroke infections.
- Further research may be warranted to optimize preventive strategies for post-stroke infections.

01:15Ischemic Stroke l: Introduction
Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
01:15Ischemic Stroke ll: Pathophysiology
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...

IntroductionThe management of Acute Coronary Syndrome (ACS) aims to minimize myocardial damage, preserve myocardial function, and prevent complications.Initial ManagementInpatient management involves continuous cardiac monitoring, preferably in an ICU, focusing on blood pressure, serum sodium, potassium, and creatinine levels, and urine output. Ongoing pharmacologic management is crucial for stabilizing the patient.Supplemental Oxygen: Administer supplemental oxygen if oxygen saturation is...
01:26Transient Ischemic Attack l: Introduction
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
