Stroke-induced Immunodepression in Neurorehabilitation

Status Completed

Clinical Trial Summary

The close interconnection between nervous system and the immune system is well known. Brain injuries lead to homeostasis disruption. On the one hand they result in increased brain inflammation contributing to tissue repair, at the expense of a possible extension of tissue damage. On the other hand, they lead to systemic down-regulation of innate and adaptive immunity, determining higher vulnerability to infections, responsible of death and comorbidities in the acute and subacute setting. Aim of the study was to evaluate the role of immunosuppression in the neurorehabilitation pathway in patients with stroke.

Clinical Trial Description

The perfect balance between nervous and immune system could be severely impaired after brain injuries, such as strokes. In the acute phase, inflammatory mediators are responsible of central nervous system inflammation, associated to tissue repair at the expense of possible secondary brain injury or damage expansions. In the mean time, activation of hypothalamic-pituitary-adrenal axis and the autonomic nervous system determine downregulation of innate and adaptive immunity, with decreased circulating T cell count and reduced lymphocytic response. The degree of these changes is linked to the severity of brain damage and inevitably lead to higher vulnerability to infections, representing a negative prognostic factor in the acute phase. Association between immunosuppression and functional outcome in the neurorehabilitation setting are missing. Aim of this study was to evaluate the role of immunosuppression in the neurorehabilitation journey in patients with stroke. We analyzed the neutrophil-to-lymphocyte ratio, a useful tool to investigate alterations in both the innate and adaptive immune systems. We correlated it to clinical and neurorehabilitation scales, investigating disability, functional status, as well as gait analysis and occurrence of infectious complications. All outcomes were measured on admission in Neurorehabilitation setting and at hospital discharge. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
