Sepsis is when your body has an unusually severe response to an infection. It’s sometimes called septicemia.

During sepsis, your immune system, which defends you from germs, releases a lot of chemicals into your blood. This triggers widespread inflammation that can lead to organ damage. Clots reduce blood flow to your limbs and internal organs, so they don’t get the nutrients and oxygen they need.

In severe cases, sepsis causes a dangerous drop in blood pressure. Doctors call this “septic shock.” It can quickly lead to organ failure, such as your lungs, kidneys, and liver. This can be deadly.

Bacterial infections are most often to blame for sepsis. But it can also happen because of other infections. It can begin anywhere bacteria, parasites, fungi, or viruses enter your body, even something as small as a hangnail.

An infection of the bone, called osteomyelitis, could lead to sepsis. In people who are hospitalized, bacteria may enter through IV lines, surgical wounds, urinary catheters, and bed sores.

Sepsis is more common in people who:

• Have weakened immune systems because of conditions like HIV or cancer or because they take drugs such as steroids or those that prevent rejection of transplanted organs
• Are pregnant
• Are very young
• Are elderly, especially if they have other health problems
• Were recently hospitalized or had major surgeries
• Use catheters or breathing tubes
• Have diabetes
• Have a serious medical condition such as appendicitis, pneumonia, meningitis, cirrhosis, or a urinary tract infection

Because it can begin in different parts of your body, sepsis can have many different symptoms. The first signs may include rapid breathing and confusion. Other common symptoms include:

• Fever and chills
• Very low body temperature
• Peeing less than usual
• Fast heartbeat
• Nausea and vomiting
• Diarrhea
• Fatigue or weakness
• Blotchy or discolored skin
• Sweating or clammy skin
• Severe pain

Your doctor will do a physical exam and run tests to look for things like:

• Bacteria in your blood or other body fluids
• Signs of infection on an X-ray, CT scan, or ultrasound
• A high or low white blood cell count
• A low number of platelets in your blood
• Low blood pressure
• Too much acid in your blood (acidosis)
• A lack of oxygen in your blood
• Problems with how your blood clots
• Uneven levels of electrolytes
• Kidney or liver problems

Your doctor will probably keep you in the hospital’s intensive care unit (ICU). Your medical team will try to stop the infection, keep your organs working, and manage your blood pressure. IV fluids and extra oxygen can help with this.

Broad-spectrum antibiotics may fight infections caused by bacteria early on. Once your doctor knows what’s causing your sepsis, they can give you medicine that targets that specific germ. Often, doctors prescribe vasopressors (which make your blood vessels narrow) to improve blood pressure. You could also get corticosteroids to fight inflammation or insulin to keep control of your blood sugar.

If your case is severe, you might need other types of treatment, like a breathing machine or kidney dialysis. Or you may need surgery to drain or clean out an infection.

As sepsis gets worse, it causes more problems throughout your body. These may include:

• Kidney failure
• Dead tissue (gangrene) on fingers and toes, leading to amputation
• Lung, brain, or heart damage
• A higher risk of infections over time

Sepsis can be deadly in between 25% and 40% of cases.  

Preventing infection is the best way to prevent sepsis. Take these steps:

• Wash your hands often with soap and water for at least 20 seconds each time.
• Keep up with recommended vaccines for things like flu and chickenpox.
• Keep control of any chronic health conditions.
• If you have an injury that’s broken your skin, clean it as soon as possible. Keep it clean and covered as it heals, and watch for signs of infection.
• Treat any infections. Get medical care right away if they don’t get better or if they seem like they’re getting worse.

Microbial ‘filters’: is there a market for new blood ‘purification’ methods?

The market for extracorporeal detoxification for sepsis could be worth several billion dollars a year. How is it that in an era of ever new advances in medicine, banal blood poisoning continues to claim so many lives?

Are infections defeated?

In January of this year, US media reported that a 70-year-old woman died in Nevada from septic shock caused by a “superbug” resistant to 26 antibiotics at once. An article about this case spread across the news feeds, giving the impression of an unprecedented event. Septic shock, the final stage of sepsis, plays the role of a static decoration in such messages: if it were possible to find a suitable antibiotic, the tragedy would not have happened, the conclusion suggests itself.

Unfortunately, this description of the situation is far from reality. Sepsis (a systemic inflammatory response to infection, not in individual organs, but throughout the body), caused by the most common pathogens, continues to claim many lives. According to the authors of the article “Economic aspects of severe sepsis”, the direct costs of treating each patient alone in the United States amount to $ 20,000-30,000. Indirect costs associated with disability further increase this figure by 70-80%. The number of annually diagnosed cases in the United States exceeds 1 million, and this figure continues to grow. How is it that in an era of ever-increasing medical advances, sepsis continues to claim so many lives?

The dizzying pace of development of chemistry and biology in the 20th century ensured the creation of hundreds and thousands of effective drugs for a variety of diseases. From the outside, it may seem that creating a cure for any disease is just a matter of time. It seems that the need for therapeutic solutions of a different type has disappeared these days. Is it so?

The intensive development of the pharmaceutical industry has required the formation of a set of strict rules for evaluating the effectiveness and safety of drugs. The classical way of drug registration includes preclinical studies, and then several stages of clinical trials. The probability of failure increases at each next stage, the cost of an error increases with each step. “Stumble at the finish line” is more expensive and more offensive than at the beginning of the journey.

The statistics from 2006 to 2016 in the USA is as follows: the probability of successful completion of a series of clinical trials is only 9.2%. At the same time, for different groups of diseases, the numbers differ significantly. “Anti-record” for drugs for the treatment of oncological, psychiatric and neurological diseases: a discouraging 5-6% reach the finish line. “Record holders” – drugs for the treatment of infectious diseases with a probability of successful completion of clinical trials – 19.1%. Estimating the total costs of developing new drugs is not easy, the process takes many years and involves the work of many specialists. But for ready-made solutions, drugs with proven effectiveness, pharmaceutical giants are ready to shell out billions of dollars in cash (such is the story, for example, Cubist Pharmaceuticals)

What is the reason for such a low probability of successful development of a new drug?

Molecular targets

The creators of new drugs determine the targets that will be affected by a particular molecule. Cells “communicate” with each other, producing hundreds of different substances per second and releasing these factors into the intercellular space. This is something like letters sealed in a bottle that other recipient cells can receive in order to send a response in the same way. In this complex process, failures are inevitable, and then diseases arise. The more violations, the more “firmly stands” the disease, the more difficult it is to cure it, affecting only one of its molecular preconditions.

Enzymes and receptors that can act as molecular targets for drugs in the body are countless. Therefore, in addition to the main mechanism of action of the substance, there are side effects – often poorly predictable. The medicine may end up in spam before being read, and this is not the worst scenario, because it can accidentally interfere with some vital process. Creating a substance of the desired “shape” capable of binding to the desired target is easier than bringing it to this goal past the many biochemical processes competing for it.

Therefore, the creators of new drugs “cut off” on many difficult questions:

• what other substances (metabolites) will our drug turn into in the human body?
• Will they be able to leave it?
• how fast will it happen?
• What tissues and organs can it get into, and which can’t?
• Would taking the drug cause more benefit or harm to the patient overall?

We often take aspirin to bring down the temperature and relieve pain when the body has an immune response to an infection. For the first time this substance was obtained by Bayer employee, chemist Felix Hoffman, in 1897 year. The discovery of its healing properties was a happy accident, because he did not yet know (and could not know) that, once in the body, it would bind to the cyclooxygenase enzyme (which plays a key role in the development of the inflammatory process). The action of aspirin was described in detail and its transformations in the body were described much later. In 1982, the Nobel Prize was awarded to the researchers John Wayne, Sune Bergström and Bengt Samuelson.

It soon became clear that the long and thorny road to new drugs only begins with the search for molecular targets and the proposed mechanism of action, and does not end with them. It is also necessary to take into account such aspects of the behavior of a substance in the body as bioavailability and pharmacokinetics, and they determine the ratio between the effectiveness of the drug and its toxicity.

New approaches

Do you remember Lord Kelvin’s saying about “two clouds in the clear sky of classical physics”? It was from two problems that classical physics could not split (the propagation of electromagnetic waves in a vacuum and the explanation of the radiation spectrum of a heated body) that the theory of relativity and quantum mechanics were subsequently born. In drug development, there may be the same “two clouds”, two potential ways to solve problems with bioavailability and toxicity.

Firstly, today the attention of researchers is attracted by technologies of “targeted delivery” of drugs. They suggest that the drug, thanks to new types of dosage forms (based on micro- or nano-sized “containers”), gets directly into the right organs, tissues and cells. Such methods are actively developing, demonstrating individual achievements, but so far they have not managed to demonstrate great success on a wide front, and perhaps they need a fresh look from an unexpected angle.

Secondly, although it is less obvious, extracorporeal methods of treatment (based on physical and chemical processing of blood) can claim the role of such a cloud. They involve the direct extraction from the body of substances involved in the development of the disease. The history of these methods has more than one thousand years (Hippocrates, the author of the doctrine of the “vital juices” of the body, recommended getting rid of excess of one of them, blood, for example, with a runny nose or headache).

I want to dwell on the second method in more detail. Advances in drug development have pushed these unusual therapies to the periphery, but they have not completely eliminated the need for them.

The most impressive achievement of extracorporeal methods has been the industry of hemodialysis, renal replacement therapy (according to Marketsandmarkets, about $ 84 billion by 2021, financed from the budgets of both governments and insurance companies). Millions of people with severe, often incurable, kidney failure are able to live full lives for many years, using “artificial kidneys” to remove accumulated urea, creatinine and other toxic substances from the blood. This breakthrough has been made possible by the creation of porous polymeric materials that are used as blood-contacting filtration membranes.

Creating materials that are highly compatible with blood has proven to be a challenge. Red blood cells, erythrocytes, are easily damaged by contact with hard surfaces. Platelets “stick” to them, forming clots. It was necessary to create a surface with which blood cells would “peacefully coexist”, as well as to choose a porous structure for it that could separate the components. Due to the physical limitations placed on the size of these pores, hemodialysis has been shown to be effective in removing relatively small molecules (such as the mentioned urea and creatinine) from the blood, as well as heavy metal ions and drugs in overdose. Therefore, today, the extracorporeal departments in hospitals, except for the most advanced ones, usually specialize in hemodialysis and emergency care for poisoning. The most advanced departments, thanks to the method, help people suffering from severe hereditary autoimmune diseases. Another direction is the removal of excess cholesterol from the blood.

“Filters” for germs

Now we are finally ready to talk about sepsis, “blood poisoning”. I would like to put it on a par with the plague, measles or consumption – not so much a disease as the “execution of Egypt”, an ancient enemy of the human race. How can extracorporeal methods help in the treatment of sepsis, what does the talk about molecular targets and classical drug design have to do with them, and why, in my opinion, the prospects for the latter are vague here?

Sepsis has been and remains a global health problem, with one estimate of about 31. 5 million deaths each year. It seems that we have learned to deal with microbes well (the audience’s stormy response to reports of the emergence of highly resistant strains is confirmation of this), therefore, sepsis should also recede, but these expectations are still very far from reality. Even in developed countries such as the United States, mortality from severe sepsis reaches 30-50%. It remains one of the most common causes of death in hospitalized patients.

We learned to understand the mechanisms of sepsis development relatively recently. Every second, the immune system “feels” our body from the inside in search of foreign substances and microorganisms. Over hundreds of thousands of years of evolution, she has learned to very confidently distinguish between the surface of the cells of our body and the cells of pathogens. By identifying them, she launches “emergency measures”. It turned out that the description of infectious agents is contained in the human genome (for this discovery in 2011, the American immunologist Bruce Butler received the Nobel Prize).

We often have a “conflict of interest” with our own immunity. Signs that he is doing his job well – fever, pain, redness, swelling, itching – are usually perceived by us as part of the disease itself. Aspirin was the first successful attempt to resolve this conflict. But in the case of sepsis, the activity of the immune system goes too far, destroying the tissues and organs of our body. Antibiotics cannot solve these problems, no matter how effective and reliable they are. The trigger for sepsis is microbial endotoxins – fragments of the outer wall of their cells, so well known to the immune system. Circulating through the body, they continue to signal danger, provoking it to fight infection at any cost.

Substances of this type have been known to scientists for more than a hundred years, during which time it was possible to study their features in detail. The researchers logically assumed that they would become the basis for the search for molecular targets. But an attempt to fight sepsis by influencing the work of the immune system, to regulate its activity with a medicine, did not lead to success.

In 2001, Eli Lilly with Xigris (Zigris) was able to go through all the stages of clinical trials and received FDA approval. The most optimistic expectations were associated with Zigris, the company’s annual revenue target was $1 billion. When sales were lower than predicted amid critical reviews from doctors, the pharmaceutical company spent another $1.8 million on aggressive lobbying methods and an attempt to bring this drug into the treatment standards. ten years, after the publication of an independent study (it showed the ineffectiveness and even the danger of the drug), Zigris was discontinued. Bioavailability and toxicity once again proved to be barriers to effective drug development, confirming that strong binding to the right molecular targets in the lab does not guarantee success at the scale of the organism.

The “bright future” that targeted drug delivery technologies paint involves reducing risks by “bracketing” the most poorly predicted aspects of drug behavior in the body. It turns out that extracorporeal methods, armed with the latest achievements of medicinal chemistry, allow us to approach this goal, albeit from the opposite side.

The idea is quite simple. If bacterial endotoxins circulate in the blood of patients with sepsis, and if it is difficult to create drugs for them (the story with Zigris proves this), then perhaps it is worth trying to extract them directly? Today, organic synthesis technologies make it possible to obtain a substance that can firmly bind to almost any target, including endotoxin.

To reduce the chance of side effects, instead of injecting this substance into the body, the molecule can be attached to the surface of a polymer that is highly compatible with blood, and then placed in a “filter element”. It will turn out a “trap” for endotoxins, in a professional language – a hemosorption column (the author’s company develops, manufactures and sells a similar solution – Forbes). By passing the patient’s blood through it, endotoxin substances can be removed from it, returning it to the body purified. This type of extracorporeal therapy is called selective LPS sorption (LPS is short for lipopolysaccharide, the chemical name for bacterial endotoxin).

However, in the short years that LPS-sorption has been used (dozens of clinical studies have already been carried out, their results have been published in highly-rated peer-reviewed scientific journals (as an example, three publications – 1,2,3), it has become clear: the method cannot be considered ” silver bullet.” As it turned out, the effectiveness of the method was not the same for different patients.

It turned out that the chances of patients to survive increase significantly if LPS sorption is carried out in the first hours of developing septic complications. The likelihood of postoperative complications can be reduced if carried out procedure directly on the operating table, but modern biocompatible polymers used as an absorbing material made it possible to reduce the number of undesirable side reactions to almost zero.0005

In a word, the sooner we apply the method to fight sepsis, the greater the effect will be. However, so far these considerations run counter to the usual ideas about the role of extracorporeal detoxification methods, which are often remembered at the last moment, “for good luck”, when nothing else helps.

At the end of 2016, a Phase 3 clinical trial of a solution from Japan called Toraymyxin was completed in the US. The researchers are awaiting publication of the results. At the same time, tests are underway on a new device for extracorporeal therapy of sepsis based on the membrane principle of separation (the patient’s blood is allowed through a membrane filter). This method can easily be integrated into the excellent hemodialysis (renal replacement therapy) industry, so it may be cheaper to implement. And in January 2017, the world’s leading manufacturer of solutions for extracorporeal therapy, Fresenius Medical Care, signed an agreement with the American manufacturer of hemosorption columns CytoSorbents, arranged according to a different principle, not capable of selectively absorbing bacterial endotoxins, but also used in the treatment of sepsis and a similar condition, the so-called “systemic inflammatory response”. Around the world, tens of thousands of patients have already been able to overcome sepsis with the help of such unusual treatments, and their number is growing every year.

Every year, on average, 50 out of 100,000 people are at risk of being hospitalized with symptoms of sepsis. For Russia, this gives a minimum of 60,000 patients per year, for Europe – 300,000, for Asia – 1. 8 million people. According to a conservative estimate, 10-20% of this number of patients have medical indications for LPS sorption. If we assume that one or two hemosorption columns are consumed per patient, and its price is in the range of $1000-3000, then the total volume of the Eurasian market reaches several billion dollars.

Expanding indications could be a key driver of growth, and many of the ongoing clinical trials are targeting this.

The history of the use of extracorporeal methods in medicine has come a long way from “bleeding” to selective LPS sorption. Procedures with insufficiently proven effectiveness before our eyes are turning into effective techniques based on the most modern ideas about the molecular mechanisms responsible for the development of critical conditions. Advanced methods for producing polymeric materials make it possible to realize these ideas. They find applications to effectively combat such a serious disease as sepsis.

What’s next? With the growth of access to high-tech medicine, every inhabitant of the Earth is more likely to encounter complications of surgical interventions, and highly resistant pathogens of nosocomial infections seem to become inevitable. All this additionally emphasizes the importance of finding new methods in the fight against complications of infectious diseases that will reduce the need for the use of antimicrobials, and if not cancel the coming “antibiotic era decline”, then at least delay its onset. Therefore, today a lot of expectations are associated with the further development of LPS sorption technologies and other related methods, which have already saved many lives.

Through a scratch: deaths from blood poisoning have decreased in Russia | Articles

Russian doctors managed to reduce mortality from sepsis to 29%. Previously, almost half of hospitalized severe patients died from blood poisoning – 45%, reported at the forum for the World Sepsis Day, held in St. Petersburg. Izvestia found out what blood poisoning is, whether it can arise from a scratch or a squeezed out pimple, and what are the symptoms and prognosis of a dangerous disease.

Medical successes

The septic forum was timed to coincide with the anniversary of the country’s only Severe Sepsis Treatment Center operating on the basis of the Janelidze Research Institute for Emergency Medicine. The head physician of the center, Professor Sergei Shlyapnikov, said that more than 600 seriously ill patients are treated there every year.

The staff of the center also explains to doctors of other specialties how to properly treat sepsis. They were able to prove that about 95% of infections come from a weakened patient’s body and only 5% of patients receive it in a hospital.

“The treatment of purulent infections has become a separate branch. We work with the staff, train them and say that there is no need to be afraid to transfer difficult patients to our center. But the patients themselves should know that blood poisoning is not a joke. The area around the wound is inflamed, reddened, the temperature rises – immediately see a doctor! the professor concluded.

Every year, 6 to 11 million people die from sepsis worldwide. The World Health Organization (WHO) has declared it the main health threat of the current century. The disease remains one of the most terrible complications in almost all areas of medicine, doctors admit.

What is sepsis

Sepsis is a purulent-septic infection of the blood. This condition is extremely life-threatening – it causes damage to internal organs and the whole body, Nadezhda Fomina, an infectious disease doctor at the Federal Scientific and Practical Center of the Federal Medical and Biological Agency of Russia, explains to Izvestia.

According to her, the causes of sepsis can be any viruses, bacteria and fungi. Infection can be triggered by immunodeficiency in humans or caused from outside.

– Sepsis can develop in the presence of otitis media, severe sore throat, meningococcal infection, or when the skin has wounds, burns, or ulcers. Microbes can get into the bloodstream even through an ordinary scratch, so when treating any infection, it is important to pay great attention to preventive measures and follow antiseptic rules, the doctor says.

According to the WHO, more than 30 million people develop blood poisoning each year, including 3 million children. One in ten deaths due to pregnancy and childbirth is due to maternal sepsis. This problem is most prevalent in low- and middle-income countries.

In the case of , sepsis can cause septic shock, multiple organ failure, and death if the person is not recognized early and treated. To make matters worse, such infections are often resistant to antibiotics.

At risk for blood poisoning are children under one year of age who do not yet have a sufficiently developed immune system, the elderly, and those who have reduced immunity due to drug suppression (for example, people with autoimmune diseases receiving chemotherapy) or due to chronic diseases, especially HIV-infected in the stage of AIDS.

Symptoms of sepsis

According to Nadezhda Fomina, disinfection of damaged skin areas reduces the risk of infection. If you get hurt – you need to immediately treat the skin with an antiseptic.

— Rapid diagnosis is important in the management of sepsis . If the resulting wound indicates signs of inflammation (pain, swelling or pus appeared at the site of injury), you should immediately seek medical help , – says the interlocutor of Izvestia.

Blood poisoning is also indicated by symptoms of intoxication: loss of appetite, weakness, chills, low blood pressure. Alarming signs include a temperature of 38 degrees, which may be accompanied by tachycardia and increased sweating, tachypnea (rapid shallow breathing, more than 20 per minute) and an increased or, conversely, low level of leukocytes in the blood.

— A picture of sepsis might look something like this: A patient who has recently had an infectious disease observes an increase in temperature for a long time (these can be both high rates – 39 degrees and above, as well as small deviations from the norm, like 37.5), shortness of breath, confusion (poor reaction to referring to him), may become delusional or be in a state of lethargy , – explains the expert doctor, oncologist of the medical online service “SberHealth” Suna Isakova.

Diagnosis of infection consists in identifying pathogenic microorganisms in the blood, as well as determining the level of procalcitonin in the blood. Additionally, ultrasound or computed tomography may be prescribed.

— The doctor decides on the choice of treatment method depending on the lesion and the patient’s condition – it can be antibiotic therapy or surgical intervention. Complications from blood poisoning can be very serious, since inflammation develops quickly and can lead to the failure of vital organs , – says infectious disease specialist Nadezhda Fomina.

Prevention and treatment

The main difficulties in the treatment of sepsis are associated with resistance to antibiotics and delayed initiation of therapy. It can be delayed in time due to the complexity of diagnosis and the non-specificity of symptoms.

— Sepsis can be caused by a wide range of pathogens, so its early symptoms are easy to miss. Laboratory tests can definitely tell about its development,” says Olga Bakshutova, head of the digital medicine department at VSK Insurance House. — After establishing the diagnosis, it is important to choose an antibiotic. And this is not easy: many pathogens acquire resistance to antibiotics, adapt to their effects and are not amenable to treatment with these drugs.

At the same time, the patient himself is in a weakened state, and in people with immunodeficiency conditions, the infection can take a fulminant course and develop in a short time.

That is why doctors recommend focusing efforts on the prevention of blood poisoning: in everyday life, this means maintaining cleanliness, cleaning hands and damaged skin, timely vaccination and contacting a doctor.
