Long COVID

Some people who had COVID-19 continue to have symptoms for weeks, months, or even years after their infection. This is often called "Long COVID" or Post-Acute Sequelae of SARS-CoV-2 (PASC). For some people, Long COVID can affect the heart and lungs, making it harder to exercise or carry out daily activities. It can also affect mental health and quality of life. This study is testing a new care model called PERCEIVE-Outreach, designed to help people living with Long COVID who may have ongoing heart or lung problems. The model involves three parts: 1. Screening: A simple assessment to identify people most likely to benefit from further care, based on symptoms and activity levels. 2. Clinical review: A thorough check of heart and lung health conducted remotely via telehealth. 3. Personalised exercise program: A tailored program to help improve fitness and reduce time spent sitting, delivered entirely via telehealth. The main thing this study is measuring is whether participants can walk further after 6 months compared to when they started (measured using a 6-minute walk test), which correlates well with an individuals ability to complete normal daily functions. The study will also look at quality of life, mental health, physical activity, heart function, and hospital visits over 2 years. The study is designed with input from patients and healthcare providers to ensure it meets real-world needs. All care is delivered remotely, meaning participants can take part from home anywhere in Australia.

The Long-Covid (LC)-Revitalize clinical study is testing repurposed drug treatments for Long Covid, involving adult participants from Brazil, Canada, Italy, South Africa, Uganda, the United States, and Zambia. To qualify, participants must have had Covid-19 and experienced Long Covid symptoms for at least three months. The main goal of the study is to determine whether the drug treatments can improve symptoms in five key areas: 1) fatigue, 2) breathing, 3) memory, thinking, and communication, 4) muscle and joint pain, and 5) circulation. A secondary goal is to assess changes in the body, such as reducing inflammation, as well as to confirm the safety and tolerability of the treatments. In the first phase, 348 participants will take either one of two existing medications (upadacitinib or pirfenidone) or a placebo (a pill with no active ingredient) for three months. Although these medications are not yet approved for Long Covid, they are authorized for use in treating other health conditions. This study is adaptive, meaning it may adjust based on early results. In the second phase, the study could continue testing the most effective drug(s) against a placebo with new participants, explore combinations of drugs to see if they improve results, or discontinue the drugs if they prove ineffective or unsafe and test alternative treatments.

Post-acute sequelae of SARS-CoV-2 infection (PASC) is becoming a major risk factor for chronic diseases, with older adults and those with underlying health conditions at risk of developing persistent mobility limitations and disabilities. Although exercise intervention is a common strategy to restore functional capacity, it may not be feasible or enticing to many people with PASC. This clinical trial seeks to establish the tolerability and efficacy of at home lower-body heat therapy for improving functional capacity along with metabolic and vascular health in late-middle aged and older adults with PASC, also known as "long COVID".

This study will examine the safety and effectiveness of Anktiva in treating patients with Long COVID-19 which is defined as persistent symptoms of a COVID-19 infection that remain after the infection is over.

The overarching goal of this study is to determine if baricitinib, as compared to placebo, will improve neurocognitive function, along with measures of physical function, quality of life, post-exertional malaise, effect of breathlessness on daily activities, post-COVID-19 symptom burden, and biomarkers of inflammation and viral measures, in participants with Long COVID.

The COVID-19 pandemic has swept across the globe, affecting millions of individuals with varying degrees of severity. While many individuals recover from the acute phase of the infection, a significant proportion continue to experience persistent and debilitating symptoms long after the initial SARS-CoV-2 infection. This condition, known as Long COVID (LC) or sometimes referred to as Post-COVID Condition (PCC) or post-acute sequelae of COVID-19, has emerged as a complex multisystemic condition and challenging health issue, affecting approximately 10% of COVID-19 patients. Various symptoms characterize LC, including fatigue, sleep disturbances, cognitive impairment, and mood disturbances. Some of the symptoms are shared with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) - a condition marked by debilitating fatigue and a host of other symptoms without precise biomarkers or objective tests for diagnosis. Effective LC treatments remain elusive and LC patients continue to grapple with persistent symptoms that significantly impact their quality of life. Given the lack of effective treatments, it is imperative to explore novel therapeutic approaches that may alleviate the suffering of this patient population.

The LIH DDP research team focuses its research topics on vocal biomarkers and Long COVID, among others. Voice is indeed a promising tool to monitor health, as it contains many information on our health and is easy to collect. The development of vocal biomarkers of Long COVID-related symptoms could improve the remote monitoring of the health status of people affected by this disease. The LIH developed the Long COVID Companion (LCC) app in collaboration with the ApresJ20 Long COVID patient association in France to support patients in their daily lives. LCC app users will be invited to participate in this study to collect voice recordings at the same time as health-related data. The objectives of this study are: Primary objective: To develop vocal biomarker candidates for the main Long COVID symptoms (fatigue, brain fog, respiratory problems, sleep issues, stress, anxiety,..) in a population of people with Long COVID. Secondary objectives: * to assess the intra-individual longitudinal evolution of voice characteristics of people with LC * to assess app usability and acceptability in the long-term.

Despite the controversy, on October 6, 2021, the World Health Organization (WHO) recognized Long Coronavirus disease (COVID) by officially defining it: " symptoms appeared 3 months after the onset of the primary infection by the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2), persisting for at least 2 months and which cannot be explained by any other condition ". Long COVID can affects any type of patient and has polymorphic and fluctuating symptoms over time. The Reunion Island is a French overseas department located in the Indian Ocean accounting more than 860,000 inhabitants. It has recorded since March 11, 2020, nearly 491,825 cases of COVID-19 and 961 deaths of hospitalized patients. Reunion's population is multi-ethnic and younger than the metropolitan France's one. It also has a higher prevalence of obesity and type 2 diabetes, two serious form factors of COVID-19. This specific context makes this island a particular study site for Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) and Long COVID. In addition, some studies have confirmed the involvement of the autonomic nervous system (ANS) in the symptomatology of Long COVID and demonstrated that patients with a Long COVID present a dysfunction of their ANS which is objectified by a reduced Heart Rate Variability (HRV). The regulation of heart rate by the ANS is strongly favored by respiration. A regular slow and deep breathing training helps to adjust the baroreflex, which connect heart rate, breathing and blood pressure. The result of this training is an induced state called "cardiac coherence" (CC). The investigator therefore hypothesize that respiratory training to CC could "re-educate" the ANS and durably improve the symptomatology of patients with Long COVID.

This research is being done to study a mindfulness intervention among people who have symptoms of Post-Acute Sequelae of SARS-CoV-2 infection (PASC), also known as Long COVID. Mindfulness is defined as paying attention to the present moment with non-judgment and acceptance. Here the investigators are studying whether a mindfulness intervention can help reduce stress, reduce Long COVID symptoms, and improve quality of life among people living with Long COVID. The mindfulness intervention is a series of recorded mindfulness sessions, which were created by the study team. People who decide to take part will be randomly assigned to receive the study mindfulness intervention immediately after joining the study or to receive the study mindfulness intervention 8 weeks after joining the study. All participants will continue their usual medical care. Participants will complete online surveys to measure symptoms over time. The study will last 6 months.

This study investigates objective methods to measure and monitor fatigue in patients with post-COVID-19 condition (long COVID) and multiple sclerosis (MS), and includes a group of healthy volunteers for comparison. Fatigue is a common and debilitating symptom of both conditions, but current assessment methods rely mainly on questionnaires, which can be limited by subjectivity and recall bias. The study uses a smartphone application (the FIDO app) together with wearable devices to continuously collect data on fatigue and its fluctuations during daily life, in order to evaluate the potential of digital, objective measures compared to standard assessments. Participation lasts approximately eight weeks and includes two in-person clinic visits along with a continuous data collection phase. At the initial visit, participants complete baseline assessments and questionnaires and are introduced to the study's digital tools. During the following weeks, participants wear two wearable devices continuously (24 hours a day) and use the FIDO app to complete short daily tasks (approximately 7 minutes every two days) and brief questionnaires (approximately 5 minutes per day). All participants collect a stool sample at home at weeks 4 and 8 for gut microbiome analysis, and complete the Fatigue Scale for Motor and Cognitive Functions at week 4. At the final study visit, participants repeat a subset of the baseline assessments, provide feedback on the digital technology used, and return the study devices.

Background: SARS-CoV-2 is the virus that causes COVID-19. Some people who recover from COVID-19 have long-term symptoms that affect the brain. These include headaches; loss of taste and smell; sleep problems; thinking problems; depression; and anxiety. Researchers want to know if a tracer (a substance that is injected into a person s body before an imaging scan) can help identify inflammation in people with these brain disorders. Objective: To see if a radioactive tracer (\[11C\]PS13) can highlight brain inflammation in those who had COVID-19 but still have symptoms that affect the brain. Eligibility: Adults aged 18 to 70 years with post COVID-19 brain disorders who are enrolled in protocol 000089 or 000711. Healthy volunteers are also needed. Design: Participants will have up to 5 clinic visits. Participants will be screened. They will have blood tests and a test of their heart function. They will have imaging scans: Magnetic resonance imaging (MRI): They will lie on a table that slides into a metal tube. Pictures will be taken of the brain. Positron emission tomography (PET): A needle attached to a thin tube will be inserted into a vein in the arm. The tracer will be injected through the tube. Another needle attached to a thin tube will be inserted into the wrist or inside of the elbow of the other arm to draw blood. They will lie still on a bed while a machine captures images of their brain. The scan will last about 2 hours. Study involvement is 11 to 14 weeks....

The purpose of this study is to better understand the biological changes associated with Long COVID and to identify laboratory tests (biomarkers) that may help diagnose the condition and measure how it changes over time. Researchers will enroll people with Long COVID as well as people who have fully recovered after COVID-19 infection. Participants will provide health information and biological samples, such as blood, saliva, stool, and, for some participants, tissue biopsies. These samples will be used to study the biological processes involved in Long COVID and to support the development of new diagnostic tests that may improve future research, clinical trials, and patient care.

This multicenter, observational, retrospective-prospective study aims to evaluate the prevalence and trajectory of Post-Acute Sequelae of COVID-19 (PASC) approximately 5 years after SARS-CoV-2 infection. The study will re-contact participants from an established cohort of more than 3,000 individuals with microbiologically confirmed SARS-CoV-2 infection, including both hospitalized and non-hospitalized patients, previously followed in dedicated post-COVID outpatient clinics. Participants will undergo a structured telephone interview approximately 60 ± 3 months after infection, and those meeting predefined clinical criteria will be invited to an in-person clinical assessment. The study will evaluate persistent symptoms, functional status, cognitive and nutritional status, frailty, sarcopenia, quality of life, healthcare resource utilization, and direct and indirect healthcare costs to characterize the long-term trajectory of PASC.

The COVID-19 pandemic has swept across the globe, affecting millions of individuals with varying degrees of severity. While many individuals recover from the acute phase of the infection, a significant proportion continue to experience persistent and debilitating symptoms long after the initial SARS-CoV-2 infection. This condition, known as Long COVID (LC) or sometimes referred to as Post-COVID Condition (PCC) or post-acute sequelae of COVID-19 (PASC), has emerged as a complex multisystemic condition and challenging public health issue. Contrary to initial perceptions, pediatric Long COVID is a significant health concern, with studies suggesting its prevalence ranges from 10% to 25% following infection. Research in the pediatric population has largely been limited to observational studies based on self-reported symptoms or large electronic healthcare datasets. The long-term outcomes and predictors of LC in children remain poorly described, highlighting an urgent need for further mechanistic research to characterize this complex condition. While acute COVID-19 symptoms are often milder in children relative to adults, some go on to develop a range of chronic physical, immunological, psychological, and neurological symptoms persisting for weeks to years after initial infection. The most commonly reported symptoms are similar to those seen in adults and include debilitating fatigue, respiratory distress, headaches, gastrointestinal symptoms, and neurocognitive impairment. Other frequently reported symptoms include muscle pain, sleep disturbances, olfactory and gustatory disturbances, exercise intolerance, and heart palpitations/cardiovascular symptoms. These symptoms can be new, or they may persist or fluctuate from the initial illness. Additionally, many children with LC experience psychological symptoms such as anxiety, depression, and mood disturbances, which are thought to be exacerbated by experiencing prolonged illness and subsequent lifestyle disruptions. Currently, effective treatments for LC remain elusive, leaving patients to contend with persistent symptoms that significantly impair their quality of life. For children and adolescents, these issues can profoundly impact their daily activities, academic performance, and social interactions/friendships. Symptoms like debilitating fatigue, cognitive impairment, and mood disturbances are especially disruptive by interfering with memory, energy levels, and overall development, often leading to school absenteeism, social withdrawal, and psychological distress. Therefore, it is imperative to explore novel therapeutic approaches that may alleviate the suffering of this patient population.

The proposed focuses on improving both morbidity and mortality in older Veterans and those recovering from COVID-19 by developing rehabilitation therapies to augment vascular endothelial function by combating the oxidative stress and inflammation associated with aging and further induced by COVID-19. The investigators expected outcomes will have an important positive impact because they will provide scientifically sound recommendations for rehabilitation to improve vascular endothelial function and minimize the long-term consequences of COVID-19.

Long COVID can cause persistent symptoms such as fatigue, cognitive difficulties commonly described as brain fog, reduced exercise tolerance, and impaired quality of life. Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that may help modulate brain activity in regions involved in cognition, fatigue, and executive function. The NEUROSTIM-LC study will evaluate the feasibility and potential effects of repeated tDCS sessions in adults with long COVID presenting fatigue and/or brain fog. Participants will receive 30 sessions of tDCS applied over the left dorsolateral prefrontal cortex. Assessments will be performed before and after the intervention to evaluate changes in quality of life, fatigue, cognitive function, brain metabolism, physical performance, autonomic function, sleep quality, psychological symptoms, respiratory function, and blood biomarkers.

The goal of this clinical trial is to test whether a type of rapid outpatient brain stimulation that uses magnetic fields, called accelerated intermittent theta burst stimulation (iTBS), can treat symptoms such as brain fog, depression, and anxiety in patients with Long COVID. The main questions it aims to answer are: * Is iTBS effective and feasible for reducing Long COVID symptoms? We will measure these symptoms using the Symptom Burden Questionnaire. * Are there changes in inflammatory brain chemicals associated with treatment with iTBS? We will be looking at levels of choline in the brain, which is thought to be related to inflammation. Researchers will compare sham versus active forms of iTBS to see if the active group has greater improvement in symptoms. Participants will complete symptom surveys, cognitive tests, and magnetic resonance imaging scans at the beginning, middle, and end of treatment.

The objective of this protocol is to use a case-control paradigm to compare the response to an intravenous administration of kisspeptin in individuals with and without post-covid-19 syndrome. The study subjects will receive a single bolus of kisspeptin.

Long COVID affects about 6 in 100 people after a COVID-19 infection. It can cause ongoing problems like ongoing tiredness, muscle pain, and "brain fog." We know very little about which treatments might be helpful for long COVID. The goal of this trial is to compare two treatments for people with long COVID to try to manage their symptoms. The main question is to assess whether the Lightning Process is effective for people living with long COVID compared to activity pacing. Each person will be placed into one of the two groups randomly (by chance, like flipping a coin). Activity pacing helps people balance rest and daily activities. The Lightning Process teaches ways to change thought patterns and body responses to symptoms. We will include 100 adults with long COVID. Everything will be done online, including filling out surveys about health and daily life. The goal is to find out which approach helps people feel better and improve their daily activities.

A small-scale test of the intervention, trial design and methods to explore the cumulative effectiveness of two commonly used prescribing strategies for patients with long COVID: Treatment A - prescribing a specific homeopathic remedy for long COVID, plus or minus Treatment B - a course of individually tailored treatment by a homeopath. Both interventions compared to usual care

The IMPACT Long Covid Treatment clinical study (IMPACT-LC) is testing two repurposed and previously approved drugs, Maraviroc and Atorvastatin, for the treatment of non-hospitalized subjects with Long COVID. The main goals of the clinical study are to determine if this combination drug therapy can improve neurocognitive and physical functions in Long Covid patients, such as fatigue severity, heart rate, blood pressure, digestion, breathing, dizziness, and cognitive function. A secondary goal is to determine if biomarker levels, measured by a diagnostic test, can improve during treatment. To qualify for the trial, a subject must be an adult ≥ 18 and ≤ 65 years of age and meets the WHO-defined post-COVID-19 condition and has one or more new-onset Long Covid symptom that persist ≥ 3 months after the diagnosis of acute COVID-19 infection. A total of 252 participants will take either two daily doses of two existing medications (Maraviroc and Atorvastatin together as separate tablets) or a placebo (pills with no active ingredient) for 16 weeks. Although these medications are not yet approved for Long Covid, they are FDA-approved for use in treating other health conditions.

This two-year study will evaluate the feasibility and safety of an exercise + cognitive training program to improve neurological symptoms of long-COVID. This is a two-phased trial: 1) an exercise phase and 2) a cognitive training phase. The exercise phase will be an aquatic based exercise program. A combination exercise + memory training programs designed for persons with cognitive impairment have significantly improved memory more than other single intervention groups (exercise only, cognitive training only) and given the success of combination training programs with healthy adults, it is important to adapt these programs for persons with neurological symptoms of long-COVID.

This study aims to assess the effects of both acute and chronic exposures to hypoxia and hypercapnia in patients with Long COVID syndrome.

This will be a six-week, randomized, parallel, two group, open-label design. Patients will be treated with Paragon Novel Metabolic Regulator (PNMR) + standard of care (SOC) or SOC alone for 6 weeks for the treatment of Long COVID. All patients will also be provided with with Dietary \& Lifestyle recommendations specifically designed to enhance immune system function and reduce viral proliferation. Patients will be assessed in the clinic at screening/baseline, 3 and 6 weeks while on treatment, and by telephone at 4 weeks post-treatment. All patients will be asked to fill in a diary to record their daily treatment dosage when being treated with PNMR + SOC or with SOC alone. Primary objective: To evaluate the efficacy of PNMR + (SOC) vs. SOC in the treatment and management of patients with long COVID.

The purpose of this research study is to test if the combination of three drugs, valacyclovir, celecoxib, and Paxlovid will decrease the symptoms of Long COVID in adults compared to a placebo (this does not contain the medications).
