What Are The Long-term Lung Problems After Covid-19

Neurocognitive And Mental Health Impacts

Long-Term Breathing Issues Post COVID-19

Covid-19 also seems to affect the central nervous system, with potentially long-lasting consequences. In one study from China, more than a third of 214 people hospitalized with confirmed Covid-19 had neurological symptoms, including dizziness, headaches, impaired consciousness, vision, taste/smell impairment, and nerve pain while they were ill. These symptoms were more common in patients with severe cases, where the incidence increased to 46.5 percent. Another study in France found neurologic features in 58 of 64 critically ill Covid-19 patients.

As the pandemic goes on, Elkind says, We need to be on the lookout for long-term neurocognitive problems.

Looking back to SARS and MERS suggests that Covid-19 patients may have slightly delayed onset of neurological impacts. Andrew Josephson, a doctor at the University of California San Francisco, wrote in JAMA, Although the SARS epidemic was limited to about 8,000 patients worldwide, there were some limited reports of neurologic complications of SARS that appeared in patients 2 to 3 weeks into the course of the illness. These included muscular weakness, burning or prickling, and numbness, and the breakdown of muscle tissue into the blood. Neurological injuries, including impaired balance and coordination, confusion, and coma, were also found with MERS.

People need to know this disease can linger and wreck your life and health, she says. And no one knows what to do for us.

Not Too Late To Get Vaccinated

He along with Dr. Naik and Dr. Brode said as COVID-19 cases surge prevention will be key. They encourage Texans to get vaccinated, wear masks and practice social distancing.

Take the appropriate precautions that keeps you and your loved one safe, said Dr. Brode.

Dr. Naik explained that the long-term impacts are even more concerning now with a spike in cases.

He said Austin Regional Clinic which has 32 locations had a positivity rate of 2% about three weeks ago and now theyre up to 13% positivity for COVID tests his staff is running.

It appears to be a combination of mostly folks that are unvaccinated that are becoming positive and now we have this more transmissible Delta variant, explained Dr. Naik. Thats part of the mix as well and thats leading to a higher transmission rate.

Prolonged Cardiovascular Effects After Covid

At the Brighams Division of Cardiovascular Medicine, several teams are leading trials that could answer pressing questions about the long-term effects of COVID-19 on the heart.

About a third of patients who are hospitalized for COVID-19 have evidence in their blood tests of injury to their hearts, said Peter Libby, MD, a cardiologist at the Brigham. We understand from research at the Brigham that this damage isnt the result of the coronavirus directly infecting the heart. Rather, the heart damage is caused by the inflammation the virus triggers. This can then cause long-term heart problems, such as abnormal heart rhythms or heart attacks.

Currently, Dr. Libby is collaborating on a study investigating how COVID-19 affects the endothelial cells in the large and small blood vessels. He recently published a paper in the European Heart Journal proposing that the major complications associated with COVID-19 likely involve altered endothelium functioning.

Hematological Complications And Sequelae

Acute COVID-19 has been associated with an increased risk of thrombotic events, especially in critically ill patients . The etiology of this coagulopathy is multifactorial, including microvascular dysfunction and increased expression of tissue factors in response to inflammatory cytokines, as well as the effects of hypoxia on upregulation of hypoxia-inducible transcription factors . Given the increased risk of thrombosis seen in this patient population, the routine use of intermediate-dose anticoagulation compared with standard prophylactic dose anticoagulation was recently tested in a randomized controlled fashion in critically ill patients with COVID-19 in the INSPIRATION trial. Intermediate-dose anticoagulation was not shown to reduce the composite endpoint of arterial or venous thrombosis, treatment with ECMO, or mortality at 30 days when compared with standard prophylactic-dose anticoagulation . Bleeding events are also seen, but given the low risk of major bleeding, the benefits of inpatient VTE prophylaxis outweigh the risks for most patients .

Can Coronavirus Patients Lessen The Chance Of Lung Damage

Coronavirus disease (COVID

There are things patients can do to increase their chances for less severe lung damage, Galiatsatos says.

If you have a health issue that puts you at higher risk, make sure youre doing everything you can to minimize the chance of contracting the virus. Also, make sure that your chronic health conditions are managed as well as they can be. For example, people living with diabetes, COPD or heart disease should be especially careful to manage those conditions with monitoring and taking their medications as directed.

Galiatsatos adds that proper nutrition and hydration can also help patients avoid complications of COVID-19. Staying well fed is important for overall health. Proper hydration maintains proper blood volume and healthy mucous membranes in the respiratory system, which can help them better resist infection and tissue damage.

Ambitious Study Into Long

This study, led by researchers at Imperial College London, will bring together researchers and clinicians from 15 research centres and will include patients already in COVID-19 studies, such as the Post-hospitalisation COVID-19 study.

Professor Gisli Jenkins, at Imperial College London, who is leading the study, said:

This is an ambitious study that will help us understand how common and severe the long-term pulmonary consequences of COVID-19 are, and will help us develop new treatment approaches for people suffering from long-term lung inflammation as a result of COVID-19.

Breathlessness is a big problem for many people with Long-COVID, particularly on exertion. For people with more severe lung scarring, this can be a devastating disease. We dont yet know how frequent and how long-term the consequences will be. Even if the long-term outcomes are no worse than for people with similar lung damage from flu, the sheer numbers of people who have had COVID-19 are so huge.

Science Minister Amanda Solloway said:

Professor Fiona Watt, Executive Chair of the Medical Research Council, part of UKRI which funded the study, said:

This research is key to understanding how and why the virus causes some people to suffer long-term lung effects after COVID-19 infection. It will be an important tool in developing more effective treatments for patients.

Pathologists Find Evidence Of Pre

Some symptoms may be caused by damage developed before patients contracted the coronavirus.

For nearly two years, the collective attention of researchers worldwide has focused on understanding what infection with SARS-CoV-2, the coronavirus that causes COVID-19, does to the human body.

As a result, scientists have amassed evidence of a wide range of effects on the heart, lungs, brain and various other organs. Much of that insight has been gathered from autopsies of people who died from COVID-19. Yet, for the millions of people who survived the infection only to experience lingering symptoms, referred to colloquially as long COVID, much remains unknown.

Researchers at University of Michigan Health, part of Michigan Medicine, are examining lung biopsies from patients living with persistent respiratory symptoms, such as shortness of breath, to help better define the pattern of damage associated with COVID-19. Their work has led to a surprising finding: some patients symptoms could be due to damage that existed before getting COVID-19.

Some of the early publications and popular press around long COVID has implied or assumed that once you had COVID, everything that happens next is COVID-related, said senior author Jeffrey Myers, M.D., professor of anatomic pathology. Of course, that might or might not be true.

Musculoskeletal Complications And Sequelae

Musculoskeletal symptoms are among the most common complaints in COVID-19, both at disease onset and in the postacute phase . Unsurprisingly, ACE 2 receptors are found in skeletal muscle and synovial tissue, suggesting that viral invasion of these tissues contributes to symptoms . Although arthritis is associated with some viral illnesses, COVID-19 more typically causes myalgias and arthralgias without true inflammatory arthritis . Reports of new-onset rheumatological diseases after COVID-19 are mostly limited to case reports . Not unlike other critical illnesses, a major complication of severe COVID-19 is catabolic muscle wasting as a result of systemic inflammation, prolonged bed rest, and malnutrition . Physical impairments after critical illness can last for months or even years and among survivors of COVID-19, those who had more severe acute illness had more muscle weakness, more problems with mobility, and had shorter distances walked in 6 min at 6 mo follow-up . This highlights the importance of optimizing nutrition and rehabilitation, both in the early and post-acute phases of COVID-19.

What Are Symptoms Of Covid

Some pandemic survivors have long term lung problems after COVID is gone

Some people may feel short of breath. People with chronic heart, lung, and blood diseases may be at risk of severe COVID-19 symptoms, including pneumonia, acute respiratory distress, and acute respiratory failure. Patients with severe problems breathing due to COVID-19 may require oxygen therapy, a ventilator, or other airway support.

New Or Ongoing Symptoms

Some people experience a range of new or ongoing symptoms that can last weeks or months after first being infected with the virus that causes COVID-19. Unlike some of the other types of post-COVID conditions that tend only to occur in people who have had severe illness, these symptoms can happen to anyone who has had COVID-19, even if the illness was mild, or if they had no initial symptoms. People commonly report experiencing different combinations of the following symptoms:

  • Difficulty breathing or shortness of breath
  • Tiredness or fatigue
  • Change in smell or taste
  • Changes in menstrual period cycles

Neuropsychiatric Complications And Sequelae

There have been various neurological and psychiatric long-term complications associated with infection with SARS-CoV-2. Long-term symptom data from multiple different sources reported ongoing neurological findings in patients 2 mo after acute infection, including, fatigue, muscle weakness, sleep difficulties, myalgia, and headache . Such symptoms have become the hallmark of the long-COVID syndrome. Loss of smell and taste has also been a feature of infection with SARS-CoV-2 that is unique compared with other viral infections. Long-term follow-up at 2 mo found ongoing loss of taste and smell in anywhere from 11% to 13.1% of patients . With the significant burden of severe, critical illness, and acute respiratory distress syndrome associated with COVID-19, similar perturbations in cognition can be expected to those observed in prior studies in patients with ARDS. Impairments in memory , verbal fluency , and executive function have been described in ARDS survivors from other causes at 1 yr of follow-up .

Does Getting A Covid

What is exciting is that there are anecdotal reports that for these initially asymptomatic patients who tested positive and develop long COVID symptoms, after they got the vaccine, their symptoms went away, said Dr. Sanghavi. So that gives us a glimmer of hope and is why it’s imperative that anybody who’s eligible should take the vaccine.

You may see less COVID-19 around you, but it’s still there, so I strongly encourage everyone to get vaccinated, he said. It doesn’t matter which vaccine you get, but what we have seen is that all three vaccines protect against severe disease and hospitalization.

Get vaccinated and until the pandemic is over, we should continue doing our personal hygiene hand-washing and wearing masks to protect ourselves and the broader population in general, said Dr. Sanghavi.

The AMA has developed aCOVID-19 resource centeras well as aphysicians guide to COVID-19to give doctors a comprehensive place to find the latest resources and updates from the Centers for Disease Control and Prevention andtheWorld Health Organization.

What Causes Symptoms In Long Haulers

Coronavirus infections and the cardiovascular system ...

SARS-CoV-2 can attack the body in a range of ways, causing damage to the lungs, heart, nervous system, kidneys, liver and other organs. Mental health problems can arise from grief and loss, unresolved pain or fatigue, or from post-traumatic stress disorder after treatment in the intensive care unit .

Brigham says, We’re seeing a spectrum of symptoms after acute COVID-19, some of which would be expected after other critical illnesses. Some are minor, but other people may need continuing care and even readmission to the hospital. She notes that similar, lingering problems can affect patients with other serious illnesses.

But whats curious is that it seems post-COVID-19 syndrome is not just afflicting people who were very sick with the coronavirus. Patients who were never severely ill are coming to clinic and saying that their lives are different now, Brigham says.

Breathing Issues After Covid

A bad case of COVID-19 can produce scarring and other permanentproblems in the lungs, but even mild infections can cause persistent shortness of breath getting winded easily after even light exertion.

Lung recovery after COVID-19 is possible, but takes time. Experts say it can take months for a persons lung function to return to pre-COVID-19 levels. Breathing exercises and respiratory therapy can help.

What Are The Most Common Long

Long-term COVIDor post-acute COVIDaffects a multitude of organ systems, said Dr. Sanghavi. Starting from head to toe, it leaves behind multiple symptoms in a large proportion of patients who have recovered from COVID-19.

From the neuropsychiatric perspective, you have patients with brain fog or cognitive impairment, he said, adding that there are also patients with fatigue, anxiety, depression, post-traumatic stress disorder and headaches.

Then, from a lung perspective, patients have persistence of shortness of breath, or dyspnea, and require ongoing oxygen treatment even after discharge and for weeks to months because of permanent damage to the lungs, said Dr. Sanghavi. As far as the cardiac system is concerned, theres chest pain and shortness of breath.

Additionally, patients can experience persistent kidney dysfunction as well as newly diagnosed diabetes or worsened control of diabetes.

What All Of This Means For Survivors And Researchers

As all this preliminary research shows, we are still in the early days of understanding what this virus might mean for the growing number of Covid-19 survivors what symptoms they might expect to have, how long it might take them to get back to feeling normal , and what other precautions they might need to be taking.

Many people arent even receiving adequate information about when it might be safe for them to stop self-isolating. Nichols and other survivors report feeling better one day and terrible the next.

But in the chaos Covid-19 has caused in the medical systems, survivors say its hard to get attention for their ongoing struggles. The support and awareness is simply lacking, Nichols says. It is a true roller coaster of symptoms and severities, with each new day offering many unknowns: I may feel healthier one day but may feel utterly debilitated and in pain the next.

Months After Recovery Covid

New study shows increased risk of heart problems after COVID-19

Posted on by Dr. Francis Collins

The pandemic has already claimed far too many lives in the United States and around the world. Fortunately, as doctors have gained more experience in treating coronavirus disease 2019 , more people whove been hospitalized eventually will recover. This raises an important question: what does recovery look like for them?

Because COVID-19 is still a new condition, there arent a lot of data out there yet to answer that question. But a recent study of 55 people recovering from COVID-19 in China offers some early insight into the recovery of lung function . The results make clear thateven in those with a mild-to-moderate infectionthe effects of COVID-19 can persist in the lungs for months. In fact, three months after leaving the hospital about 70 percent of those in the study continued to have abnormal lung scans, an indication that the lungs are still damaged and trying to heal.

The findings in EClinicalMedicine come from a team in Henan Province, China, led by Aiguo Xu, The First Affiliated Hospital of Zhengzhou University Yanfeng Gao, Zhengzhou University and Hong Luo, Guangshan Peoples Hospital. Theyd heard about reports of lung abnormalities in patients discharged from the hospital. But it wasnt clear how long those problems stuck around.

Recovering Sense Of Smell In Covid

For patients with long-term smell disturbances, Brigham otolaryngologists Regan W. Bergmark, MD, and Alice Z. Maxfield, MD, have recommended olfactory training to some patients. This technique has been used in other types of virus-associated smell loss. For several months, patients smell different odors for five minutes in the morning and evening. The therapy aims to stimulate olfactory nerves and get them to regenerate.

In previous research on smell loss from other cold viruses, patients are more likely to improve with olfactory training, said Dr. Bergmark. We need to study these patients further to understand whether olfactory training is an effective treatment for long-term smell loss. Were currently doing that by collecting data on these patients and tracking them over time.

If I Lost My Smell Or Sense Of Taste Will I Get It Back

According to one study, 95% of the patients recover their sense of taste and smell eventually, said Dr. Sanghavi, adding that it may take months, but their sense of taste and smell sensation would come back.Initially it was thought that it is a direct invasion of virus into the olfactory cells or the neurons, but now, as we understand the process more, it seems like this impacts the helper cells and not the neurons directly, he said. And as the helper cells recover, the sense of taste and smell recover too.

People may ask if they can do anything to get it back and re-sensitization with aromatherapy is one way that could potentially work, but there is no clear proof that anything works right now, said Dr. Sanghavi.
