Serum elastase levels following a stroke in elderly subjects.

Area of Science:

• Biochemistry
• Neurology
• Gerontology

Background:

• Cerebrovascular incidents, or strokes, can lead to significant physiological changes.
• Serum elastase, an enzyme, plays a role in various biological processes.
• Age is a known factor influencing physiological responses to medical events.

Purpose of the Study:

• To investigate the correlation between serum elastase levels and stroke outcomes.
• To determine the temporal dynamics of serum elastase changes post-stroke.
• To explore the influence of patient age on these elastase level alterations.

Main Methods:

• Serum samples were collected from stroke patients.
• Elastase content in serum was quantified.
• Data were analyzed in relation to patient survival and age.

Main Results:

• Serum elastase levels were significantly elevated immediately following a stroke.
• In surviving patients, elastase levels returned to age-specific normal ranges.
• The extent of elastase elevation, time to peak, and recovery rate were age-related.
• Patients who died within one week of stroke onset showed a marked increase in serum elastase before death.

Conclusions:

• Serum elastase levels serve as a potential biomarker for stroke severity and prognosis.
• Age significantly modulates the response of serum elastase to cerebrovascular events.
• Further research could explore therapeutic interventions targeting elastase in stroke patients.
