A Two Year Longitudinal Clinical Study of Neurocognitive and Psychiatric Symptoms in Post COVID-19 Patients (PASC24)
Uppföljning av Psykiatriska, Kognitiva Och Neurologiska Symtom Hos Post COVID-19 Patienter.
Study Overview
Detailed Description
The aim is to increase knowledge of the underlying biological processes; how biomarkers correlate with degree of symptoms, mapping their role as diagnostic markers over time (24 months).
The investigators follow up to 100 study participants with post-acute sequelae of SARS-CoV-2 infection (PASC) for 24 months, measure their physical, psychological and neurocognitive symtoms and how they change over time (three visits: baseline, 12 months, 24 months) in correlation with biomarkers in blood, cerebrospinal fluid and faeces samples as well as neuroradiological changes on MRI (baseline, 24 months).
Knowledge about the late effects of COVID-19 and its pathogenesis is still unknown. The findings of the study can therefore be used as a guidance for future actions in healthcare and, in the best case, can lead to a possible, either curative or symptom-relieving, treatment.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Occurence of activity limitations and changes in health-related quality of life (QoL)
Time Frame: baseline, 12 months, 24 months
|
Rating scale: the EuroQol-5 Dimension, 5 levels (EQ-5D-5L) with EuroQol-visual analogue scale (EQ-VAS) EQ-5D-5L assesses the current state of health in five dimensions related to well-being and function; mobility, personal care, regular activities, pain/discomfort and anxiety/depression. Each dimension has five levels from "No problems" to "extreme problems". This results in a single-digit number (from 1 to 5) that expresses the level selected for that dimension. Higher digits/scores mean en worse uotcome. EQ-VAS registers the patient's self-rated health in a analog scale with the minimum and maximum values: 0-100 where the endpoints are marked: 100 -"The best health you can imagine" and 0 - "The worst health you can imagine". Lower scores mean a worse outcome. |
baseline, 12 months, 24 months
|
Grade of work incapacity/sick leave and time to return to work
Time Frame: baseline, 12 months, 24 months
|
Self-assessment questionnaire. Study participant report grade of eventual sick-leave. According to Swedish legislation, four degrees of sick leave are possible (25%, 50%, 75%, 100%), where a higher number of percentages means worse outcome i.e. more reduced ability to work. They also report the time of incapacity for work (number of months of sick leave (1- 100)) where higher numbers mean worse outcome i.e. longer time of incapacity for work |
baseline, 12 months, 24 months
|
Changes in body size
Time Frame: baseline, 12 months, 24 months
|
Body mass index (BMI) gives an indication of the body size. Along with several other factors, BMI can help estimate the risk of a cardiovascular disease. BMI is calculated using weight and height. BMI Categories: Underweight = <18.5, Normal weight = 18.5-24.9, overweight = 25-29.9, obesity = BMI of 30 or greater. The values under 18.5 and over 25 indicate worse outcome. |
baseline, 12 months, 24 months
|
Waist size
Time Frame: baseline, 12 months, 24 months
|
The waist measurement is an indicator of the abdominal obesity that is associated with an increased risk of type 2 diabetes, cardiovascular disease and death, The values over 94cm for men and over 80cm for women indicate worse outcome i.e. abdominal obesity.
|
baseline, 12 months, 24 months
|
Rate of peak expiratory flow (PEF)
Time Frame: baseline, 12 months, 24 months
|
PEF rate is the volume of air forcefully expelled from the lungs in one quick exhalation, and is an indicator of ventilation adequacy as well as airflow obstruction.
Air flow is measured with the portable, hand-held device.
Three readingss are performed ond the highest of three readings is used as the recorded value of the PEF Rate.
PEF is measured in units of liters per minute (0-800).
The expected value depends on the participant's sex, age, and height but higher numbers in the given study participant mean better outcome i.e. better lung function.
|
baseline, 12 months, 24 months
|
Grade of physical exercise capacity
Time Frame: baseline, 12 months, 24 months
|
60 Second Sit-to-Stand Test (60STS) gives a measure of exercise capacity.
The participant is encouraged to complete as many full stands as possible within 60 seconds.
The number of full stands is registered (0-100) where higher numbers mean better outcome i.e. better physical fitness.

baseline, 12 months, 24 months
|
Concetration of Beta-Amyloid 42 in cerebrospinal fluid (CSF) as a CSF biomarker of neurodegeneration.
Time Frame: baseline, 24 months
|
Beta-amyloid 40 and 42 are formed from amyloid precursor protein (APP) and are normally transported to the cerebrospinal fluid (CSF). In Alzheimer's disease, Beta-amyloid 42 accumulates in senile plaque and thus the level falls in CSF. Slightly lower levels of beta-amyloid 42 can also be seen in other dementia diseases. Cerebrospinal fluid will be collected by trained physician and results will be reported as ng/L. The expected value depends on the participant's age, but lower values in the given study participant mean worse outcome i.e. more possible neurodegeneration. |
baseline, 24 months
|
Beta Amyloid Ratio 42/40 in cerebrospinal fluid (CSF) as a CSF biomarker of neurodegeneration linked to Alzheimer's disease
Time Frame: baseline, 24 months
|
Beta amyloid 40 is the most common variant of beta amyloid in CSF, while beta amyloid 42 predominates in senile plaques . Decreased ratio of Beta amyloid 42/40 is a strong marker of Alzheimer's disease and can be detected early in the disease progression, even before clinical dementia occurs. Cerebrospinal fluid will be collected by trained physician and the result is reported as a ratio. Reference interval: > 0.72 ( > 50 years of age). Lower ratio means worse outcome i.e. possible Alzheimer's disease. |
baseline, 24 months
|
Concentration of neurogranin in cerebrospinal fluid (CSF) as a CSF biomarker of neurodegeneration linked to Alzheimer's disease
Time Frame: baseline, 24 months
|
Neurogranin is a protein expressed in synapses of the pyramidal cells of the hippocampus and cortex. Neurogranin is elevated in cerebrospinal fluid from individuals with Alzheimer's disease, but not from healthy individuals or individuals with other neurodegenerative diseases. Cerebrospinal fluid will be collected by trained physician and results will be reported as ng/L. The expected value depends on the participant's age, but higher values in the given study participant mean worse outcome i.e. more possible neurodegeneration. |
baseline, 24 months
|
Concentration of Tau (P-Tau) protein in cerebrospinal fluid (CSF) as a CSF biomarker of cortikal damage/neurodegeneration
Time Frame: baseline, 24 months
|
Tau protein is a recognized biomarker of cortical damage and is assumed to be a nonspecific marker of neurodegeneration. Cerebrospinal fluid will be collected by trained physician and results will be reported as ng/L. The expected value depends on the participant's age, but higher values in the given study participant mean worse outcome i.e. more possible cortical damage/neurodegeneration. |
baseline, 24 months
|
Concentration of phosphorylated Tau (P-Tau) in cerebrospinal fluid (CSF) as a CSF biomarker of neurodegeneration/taupathy
Time Frame: baseline, 24 months
|
Under physiological conditions, tau protein regulates the assembly and maintenance of the structural stability of microtubules in nerve cells. In certain brain diseases tau proteine becomes abnormally hyperphosphorylated, which ultimately causes the microtubules to disassemble, and the free tau molecules aggregate into paired helical filaments. Phosphorylated tau (P-tau) is assumed to be a relatively specific marker for Alzheimers disease because neurofibrillary tangles that är found in AD patients primarily consist of tau protein in the abnormally hyperphosphorylated state Cerebrospinal fluid will be collected by trained physician and results will be reported as ng/L. The expected value depends on the participant's age, but higher values in the given study participant mean worse outcome i.e. more possible neurodegeneration. |
baseline, 24 months
|
Concentration of neurofilament light (NFL) in cerebrospinal fluid (CSF) as a CSF biomarker of neurodegeneration
Time Frame: baseline, 24 months
|
Neurofilament light (NFL) is a recognized biomarker of subcortical large-caliber axonal degeneration and is assumed to be a nonspecific marker of neurodegeneration. Cerebrospinal fluid will be collected by trained physician and results will be reported as ng/L. The expected value depends on the participant's age, but higher values in the given study participant mean worse outcome i.e. more possible neurodegeneration. |
baseline, 24 months
|
Concentration of neurofilament light (NFL) in plasma as a blood biomarker of neurodegeneration
Time Frame: baseline, 24 months
|
Blood-based biomarkers of neurodegeneration have obvious advantages over both CSF and neuroimaging biomarkers. The collection of blood is inexpensive, noninvasive, and a more feasible measure for use in the general population, especially if serial collection is needed. Neurofilament light (NFL) is a recognized biomarker of subcortical large-caliber axonal degeneration and is assumed to be a nonspecific marker of neurodegeneration. Plasma will be collected by trained personnel and results will be reported as ng/L. The expected value depends on the participant's age, but higher values in the given study participant mean worse outcome i.e. more possible neurodegeneration. The values will be also compared with NFL values in cerebrospinal fluid (outcome 20), which are still the "golden standard" of NFL measurement |

Occurence of APOE4 allele as biomarker of genetic predisposition to Alzheimer's disease and susceptibility to more severe course of COVID-19 infection
Time Frame: baseline
|
The human APOE gene exists as three polymorphic alleles-ε2, ε3 and ε4-which have a worldwide frequency of 8.4%, 77.9% and 13.7%, respectively. However, the frequency of the ε4 allele is dramatically increased to ~40% in patients with late onset Alzheimers disease. APOE4 allele has also been correlated with severe COVID-19 outcomes. Plasma will be collected by trained personnel and results will be reported as combination of two alleles with six possible alternatives: 2/2, 2/3, 2/4, 3/3, 3/4, 4/4. Alternatives with the APOE4 allele indicate worse outcomes and combinationen: 4/4 indicates the worst possible outcome. |

Changes in gut microbiome
Time Frame: Baseline, 24 months
|
The gut microbiome in COVID-19 is characterized by increased fecal fungal load and increased beta-diversity (more heterogeneous), and it is unstable over time and also persistently altered after disease resolution.
Assessment of gut microbiome as well as changes over time will be carried out via analysis of the fecal samples for microbial composition using 16S microbiome analysis, metabolomics and Next Generation Sequencing.
