Understanding the Causes and Treatment of Severe COVID-19
September 25, 2023: As the world continues to grapple with the ongoing COVID-19 pandemic, researchers and doctors are constantly learning more about the factors that contribute to the varying severity of infections. While many believe that inflammation is the primary cause of severe COVID-19, new research suggests that bacterial pneumonia may play a significant role in the deaths of many patients.
The Role of Inflammation and Cytokine Storms
The prevailing belief among researchers and doctors is that inflammation, caused by a “cytokine storm,” is responsible for the severe outcomes in some COVID-19 cases. When a person’s immune system overreacts to the infection, it releases an excessive amount of cytokines, which can be toxic and lead to organ failure. This inflammatory response is thought to be a major contributor to severe illness and death in COVID-19 patients.
However, a recent study conducted by a doctor from Northwestern University and the University of Wisconsin challenges this idea. The study found that bacterial pneumonia was the cause of death in many severe COVID-19 cases, rather than inflammation. By using machine learning to analyze data, researchers discovered that half of the severely ill patients who required ventilators had bacterial pneumonia as a secondary infection. These patients showed no signs of inflammation or cytokine storms. The study’s senior author, Dr. Benjamin D. Singer, emphasized the importance of early detection and treatment of pneumonia in COVID-19 patients to improve outcomes.
The Controversy Surrounding Cytokine Storms
While the Northwestern study sheds doubt on the role of cytokine storms in severe COVID-19 cases, other researchers continue to support the cytokine storm theory. Cytokines are chemicals released by the immune system during an infection, and an excessive release of cytokines can lead to organ damage and failure. Scientists from the CSIR-Institute of Microbial Technology in Chandigarh, India, and MM Engineering College in Ambala, India conducted a study emphasizing the importance of controlling inflammation to treat COVID-19 effectively. Italian researchers have also found evidence indicating that hyperinflammation contributes to the severe illness experienced by COVID-19 patients.
The Impact of Bacterial Infections
Aside from the cytokine storm debate, recent research has also highlighted the role of specific bacteria in worsening COVID-19 outcomes. A study conducted at New York University Grossman School of Medicine found that bacteria from the gut can pass into the bloodstream of severe COVID-19 patients, potentially accelerating complications. This suggests that bacterial infections can play a significant role in the severity of COVID-19.
Identifying High-Risk Individuals
Understanding the factors that increase the risk of severe COVID-19 is crucial for identifying individuals who need extra attention and care. According to the CDC, anyone who is unvaccinated is at risk of severe COVID-19. Other factors that heighten the risk include:
- Being over 50 years old, particularly over 65 years old
- Having underlying medical conditions such as asthma, respiratory conditions, diabetes, heart disease, HIV, kidney disease, liver disease, a weakened immune system, or obesity
- Being pregnant
- Being physically inactive
- Being a smoker
Recognizing Emergency Warning Signs
It’s important to be aware of the COVID-19 symptoms that may indicate a more severe progression of the illness. These symptoms include:
- Fever
- Shaking chills
- Cough
- Shortness of breath or difficulty breathing
- Fatigue
- Muscle pains
- Body pain
- Headache
- Loss of taste
- Loss of smell
- Throat pain
- Congestion
- Runny nose
- Nausea
- Vomiting
- Diarrhea
If anyone experiences these symptoms, particularly labored breathing, chest pain, confusion, or pale, gray, or blue skin, lips, or nail beds, they should seek immediate medical attention and inform healthcare providers about their COVID-19 status.
Treatment Options for Severe COVID-19
When a patient tests positive for COVID-19 and has known risk factors, their doctor may prescribe medications to prevent the disease from progressing. Currently, there are three main medications used for this purpose: molnupiravir, Paxlovid, and remdesivir. Hospitalized patients may also receive additional drug therapy to reduce inflammation and blood plasma therapy.
In addition to COVID-19 treatment, patients may need to be treated for other co-infections. It is crucial for individuals to inform healthcare providers about any new symptoms that develop during their illness.
Preventing Severe COVID-19
The best way to avoid severe COVID-19 is to get vaccinated and receive a booster dose if eligible. Vaccination significantly reduces the risk of serious illness. Additionally, individuals should request screening for pneumonia if they test positive for COVID-19 and experience worsening respiratory symptoms. Prompt treatment with antibiotics may be necessary to address co-infections. Furthermore, avoiding junk food is recommended, as dietary sugar can exacerbate organ damage, especially when combined with antibiotics. Finally, following all prescribed medications, isolating for at least five days, wearing a high-quality mask around others, and managing stress are essential steps to minimize the severity of COVID-19.
Conclusion
The ongoing research surrounding severe COVID-19 continues to provide valuable insights into the disease’s mechanisms and potential treatment options. While the role of cytokine storms and inflammation remains a topic of debate, the connection between bacterial infections and severe outcomes is becoming increasingly evident. By understanding the risk factors, recognizing emergency warning signs, and following proper treatment and prevention strategies, individuals can take proactive measures to mitigate the severity of COVID-19 and protect their health.
Summary:
This article discusses the causes and treatment of severe COVID-19. While inflammation and cytokine storms have been widely believed to be the primary causes of severe illness, recent research suggests that bacterial pneumonia may play a significant role. The debate between the importance of cytokine storms and the impact of bacterial infections continues among researchers. Identifying high-risk individuals is crucial to provide appropriate care, and recognizing emergency warning signs is essential for timely medical attention. Treatment options include medications to prevent disease progression and additional therapies to reduce inflammation. Vaccination, pneumonia screening, and avoiding junk food are recommended preventive measures. By following these guidelines, individuals can minimize the severity of COVID-19.

September 25, 2023: As we continue to live with COVID-19, patients and doctors will learn more about the reasons why infections can range from asymptomatic to very serious. Many researchers and doctors believe that inflammation is the cause of severe COVID. This is because the virus causes a “cytokine storm” which can negatively affect organs in a patient’s body, including the heart and lungs.
New research However, a doctor from Northwestern University and the University of Wisconsin points out that bacterial pneumonia is the cause of many serious COVID deaths. The deceased COVID patients studied were not shown to have experienced any inflammation. Instead, researchers, using machine learning to analyze data, found that half of severely ill COVID patients who required a ventilator had bacterial pneumonia as a secondary infection. They found no evidence of a cytokine storm in these patients; Instead of dying from organ damage or failure due to COVID, they died from pneumonia.
“Critically ill patients who recovered from pneumonia were more likely to live,” he said. Benjamin D. Singer, MDThe study’s senior author, a professor of pulmonary medicine and a pulmonary and critical care physician at Northwestern Medicine in Chicago.
However, other researchers do not debunk the idea of cytokine storms in COVID. Cytokines are chemicals that are released when a person’s immune system overreacts to an infection. Too many cytokines are toxic and can lead to organ failure. In COVID-19, cytokines are thought to be released inflammation that can circulate through the body and cause death.
A new study from CSIR-Institute of Microbial Technology in Chandigarh, India, and MM Engineering College in Ambala, India, for example, found that controlling this inflammatory factor is essential for treating COVID. Italian researchers Additionally, they find that hyperinflammation plays a definitive role in the severe illness of COVID patients.
Additional new research shows that specific bacteria can cause negative outcomes in COVID patients. TO study at New York University Grossman School of Medicine found that bacteria from the gut can pass into the blood of patients with severe COVID. “Bacteria circulating in the blood may accelerate complications in these COVID patients,” said the study’s co-author. Jonas Schluter, PhD from the Systems Genetics Institute and assistant professor of microbiology at NYU Grossman in New York City.
Could these findings affect any patient diagnosed with COVID-19 who may be at high risk for complications? Potentially, yes. A very important aspect of the Northwestern study is that it highlights the importance of detecting pneumonia in COVID-susceptible patients as early as possible. The good news: Patients who test positive can immediately talk to their doctors about their risk factors and receive the treatment they need to prevent serious illness.
Who is at risk for severe COVID?
The CDC reports that anyone who is not vaccinated is at risk of severe COVID. Other factors include:
- Be over 50 years old, especially over 65 years old.
- Having underlying medical conditions including asthma and other respiratory conditions, diabetes, heart disease, HIV, kidney disease, liver disease, having a weakened immune system, and obesity.
- Be pregnant
- Being physically inactive
- be a smoker
What COVID symptoms are emergency warning signs?
According the CDCCOVID symptoms that can range from mild to severe include:
- Fever
- Shaking chills
- Cough
- Shortness of breath or any difficulty breathing.
- Fatigue
- Muscle pains
- Body pain
- A headache
- Loss of taste
- Loss of smell
- throat pain
- Congestion
- Rhinorrhea
- Nausea
- Vomiting
- Diarrhea
The following symptoms indicate potentially more serious or critical progression of COVID-19:
- labored breathing
- chest pain pain
- Chest pressure
- Confusion
- Trouble waking up
- Trouble staying awake
- Pale, gray, or blue skin, lips, or nail beds
Anyone experiencing any or all of these symptoms should call 911 immediately and explain that they are a possible or confirmed case of COVID.
How is severe COVID treated?
If a patient tests positive and has risk factors, their doctor may prescribe one of three medications to prevent the disease from progressing: molnupiravir, Paxlovideither remdesivir. If a patient is hospitalized, they may be given additional drug therapy that reduces inflammation, as well as blood plasma therapy.
Patients will also be treated for any other infections they have, so it is important to tell healthcare providers about new symptoms right away.
What can be done to avoid severe COVID-19?
First, get vaccinated and get a booster. “It’s the best way to prevent the likelihood of serious illness,” Singer said. “It is very rare to see a fully vaccinated COVID patient in critical condition in the ICU.”
If a patient tests positive and has worsening respiratory symptoms, they should ask their doctor to screen them for pneumonia. Antibiotics are often necessary to treat a co-infection, and Schluter gave some unexpected but important advice: stop eating junk food immediately. “You don’t want to eat junk because antibiotics and sweets don’t mix,” he warns. “Dietary sugar, combined with antibiotics, can exacerbate damage to the body’s organs. COVID can create a wildfire in your body. Not consuming excess sugar can put out the flame.”
The most important thing to do: take all prescribed medications, isolate for at least 5 days, wear a high-quality N95 or KN5 mask when you are around other people and don’t stress. Taking these measures means that a patient is doing everything right and everything possible to have the least severe outcome with COVID-19.
