Study of Pregabalin Treatment and Rehabilitation for Chronic Fatigue in Post-COVID Syndrome Patients

2 1 1

What is this study about?

This study focuses on treating chronic fatigue syndrome that develops after COVID-19 infection, also known as post-COVID syndrome. The study will evaluate the effectiveness of two different treatment approaches: medication with pregabalin tablets and complex rehabilitation. Pregabalin is a prescription medication that will be compared to a placebo during the research.

The purpose of this study is to determine how well pregabalin and complex rehabilitation help reduce fatigue symptoms in people who have experienced persistent tiredness for at least 6 months after having COVID-19. The study will measure changes in fatigue levels and physical abilities, including how far participants can walk.

During the study, participants will take either pregabalin tablets or placebo tablets. The maximum daily dose of pregabalin will be 300 mg. The study will last for 6 months, during which various aspects of participants’ health will be monitored, including their energy levels, walking ability, quality of life, sleep patterns, and emotional well-being. Regular assessments will be conducted to track participants’ progress throughout the study period.

1 Initial assessment

Your participation begins with an assessment to confirm chronic fatigue syndrome related to previous COVID-19 infection

The medical team will verify that at least 6 months have passed since your documented SARS-CoV-2 infection

Female participants will undergo a pregnancy test and must confirm using effective contraception throughout the study

2 Baseline measurements

You will complete several questionnaires about your fatigue levels, life satisfaction, and mental health

Physical tests will be conducted, including a 6-minute walking test to measure your walking distance

Various cognitive tests will be performed to assess your mental function

Blood samples will be collected to analyze inflammatory markers

3 Treatment period start

You will receive either pregabalin tablets (75 mg) or placebo tablets for oral use

The medication or placebo must be taken as prescribed throughout the study period

4 3-month assessment

After 3 months, you will undergo the same tests and questionnaires as at the beginning

Your walking ability, fatigue levels, and other symptoms will be reassessed

The medical team will check for any side effects or health changes

5 6-month assessment

Final round of tests and questionnaires will be conducted

Physical and cognitive assessments will be repeated

Blood samples will be taken for final analysis

The medical team will perform a final safety evaluation

Investigated drugs:

Pregabalin

Pregabalin is a medication commonly used to treat nerve pain and anxiety disorders. In this trial, it is being studied for its potential to help patients who experience chronic fatigue after COVID-19 infection. It works by reducing abnormal electrical signals in the nervous system and may help improve energy levels and reduce fatigue symptoms.

Complex rehabilitation is a comprehensive treatment approach that includes various physical exercises, therapeutic techniques, and lifestyle modifications. This therapy program is designed to help patients recover their strength, endurance, and daily functioning abilities after experiencing post-COVID syndrome. It typically involves supervised activities and exercises tailored to each patient’s specific needs and capabilities.

Investigated diseases:

Chronic Fatigue Syndrome (CFS) associated with Post-COVID Syndrome – A complex condition that develops after COVID-19 infection, characterized by severe fatigue that doesn’t improve with rest. Patients experience persistent exhaustion that significantly affects daily activities and can last for months. The condition often includes other symptoms such as muscle weakness, difficulty with concentration and memory, sleep problems, and reduced physical endurance. The fatigue typically worsens with physical or mental activity. The condition can fluctuate in intensity over time, with periods of increased and decreased severity.
