Gedetailleerde beschrijving
This is a prospective, phase II study of fluoxetine for motor recovery post-stroke in adults with new-onset ischemic stroke in urban Tanzania. Participants will be enrolled at the Muhimbili National Hospital (MNH) in Dar Es Salaam after confirmation of exclusion and inclusion criteria, including a head CT. Participants will be enrolled within 21 days of acute, ischemic stroke. The study will utilize a novel method for monitoring patient medication adherence: electronic pill bottles that can record medication use events. The primary goals of this study are to assess the safety and tolerability of fluoxetine post-stroke to evaluate the feasibility of conducting a larger, phase III study in the future.
Vital status will be monitored throughout the study's enrollment period. At enrollment, participants will have cognitive tests administered, receive lumbar puncture, and receive an MRI brain. After discharge from the hospital, participants will be seen at 30-, 60-, and 90-days post-enrollment for an in-person study visit. At each time point, investigators will draw 10-15 mL of blood; download medication adherence data from participants' electronic pill bottles; and inquire about adverse events and evaluate patient disability through the modified Rankin Scale. If participants stop taking their daily pill, stroke specific reasons for non-adherence will be inquired including dysphagia, self-administration, and other concerns.
Primary assessments will be for safety and tolerability, as well as measurement of the Fugl-Meyer Motor Scale. Medication use data will also be collected through the electronic pill bottle, which will be returned to study investigators. As secondary assessments, the PHQ-9, and the Asberg Depressive Symptom Questionnaire will be administered. All 90-day assessments will be administered by senior site investigators, who will take a final 10-15mL blood draw to test for serum sodium and liver enzymes, possible adverse events related to long-term fluoxetine use, conduct a second MRI brain, evaluate participant mRS, and inquire about tolerability issues. Completion of the 90-day visit and associated assessments is considered the study endpoint.

Fugl-Meyer Motor Scale Score for Assessment of Motor Function After Stroke
Tijdsspanne: 90 days following acute, ischemic stroke
|
The Fugl Meyer motor scale is used to assess post-stroke motor recovery in stroke patients.
It is scored on a scale from 0 to 100, with lower scores indicating greater disability.
It evaluates both lower and upper extremities for motor performance: 66 points are allocated to the upper extremities, 34 to the lower extremities.
The two extremities are summed to achieve the total score.

Montgomery-Asberg Depression Rating Scale
Tijdsspanne: 90 days following acute, ischemic stroke
|
10-item questionnaire used to evaluate the severity of a patient's depressive symptoms.
Each item is scored on a scale from 0 to 6, the scores are summed, and the total score (0 to 60 points) is reported.
The greater the score, the more severe the degree of depression.
|
90 days following acute, ischemic stroke
|
|
Modified Rankin Scale
Tijdsspanne: 90 days following acute, ischemic stroke
|
Validated instrument for measuring the degree of disability in stroke patients.
The modified Rankin Scale is based on a physicians subjective evaluation.
The scale ranges from 0, indicating perfect health, to 6, indicating that the patient is dead.
|
90 days following acute, ischemic stroke
|
|
The Patient Health Questionnaire-9 (PHQ-9) Scale for Measuring Depression
Tijdsspanne: 90 days following acute ischemic stroke
|
The PHQ-9 is a validated 9-point questionnaire for measuring depression symptom severity.
Each question is scored from 0-3.
Answers are summed and the total score (0 to 27) is reported.
The greater the score, the greater the severity of depression.
