What is sepsis and what are the symptoms?
- Sepsis encompasses a spectrum of illness that ranges from minor signs and symptoms through to organ dysfunction and shock Sepsis ranks in the top 10 causes of death The pathophysiology of sepsis arises largely from the response of the host's innate immune system, under the influence of genetic factors
A patient with sepsis might have one or more of the following signs or symptoms: High heart rate or low blood pressure Confusion or disorientation Extreme pain or discomfort Fever, shivering, or feeling very cold Shortness of breath Clammy or sweaty skin A medical assessment by a healthcare professional is needed to confirm sepsis.

- Risk Factors
Sepsis is a potentially life-threatening condition that occurs when the body's response to an infection damages its own tissues. When the infection-fighting processes turn on the body, they cause organs to function poorly and abnormally. Sepsis may progress to septic shock. This is a dramatic drop in blood pressure that can lead to severe organ pro...
Signs and symptoms of sepsis
To be diagnosed with sepsis, you must have a probable or confirmed infection and all of the following signs: 1. Change in mental status 2. Systolic blood pressure — the first number in a blood pressure reading — less than or equal to 100 millimeters of mercury (mm Hg) 3. Respiratory rate higher than or equal to 22 breaths a minute
Signs and symptoms of septic shock
Septic shock is a severe drop in blood pressure that results in highly abnormal problems with how cells work and produce energy. Progression to septic shock increases the risk of death. Signs of progression to septic shock include: 1. The need for medication to maintain systolic blood pressure greater than or equal to 65 mm Hg. 2. High levels of lactic acid in your blood (serum lactate). Having too much lactic acid in your blood means that your cells aren't using oxygen properly.
When to see a doctor
Most often, sepsis occurs in people who are hospitalized or who have recently been hospitalized. People in an intensive care unit are more likely to develop infections that can then lead to sepsis. Any infection, however, could lead to sepsis. See your doctor about an infection or wound that hasn't responded to treatment. Signs or symptoms, such as confusion or rapid breathing, require emergency care.
While any type of infection — bacterial, viral or fungal — can lead to sepsis, infections that more commonly result in sepsis include infections of: 1. Lungs, such as pneumonia 2. Kidney, bladder and other parts of the urinary system 3. Digestive system 4. Bloodstream (bacteremia) 5. Catheter sites 6. Wounds or burns
Several factors increase the risk of sepsis, including: 1. Older age 2. Infancy 3. Compromised immune system 4. Diabetes 5. Chronic kidney or liver disease 6. Admission to intensive care unit or longer hospital stays 7. Invasive devices, such as intravenous catheters or breathing tubes 8. Previous use of antibiotics or corticosteroids
As sepsis worsens, blood flow to vital organs, such as your brain, heart and kidneys, becomes impaired. Sepsis may cause abnormal blood clotting that results in small clots or burst blood vessels that damage or destroy tissues. Most people recover from mild sepsis, but the mortality rate for septic shock is about 40%. Also, an episode of severe sep...

Oct 27, 2007 · Systemic illness caused by microbial invasion of normally sterile parts of the body is referred to as “sepsis.” This is a term that specifically serves to differentiate an illness of microbial origin from an identical clinical syndrome that can arise in several non-microbial conditions, of which pancreatitis is the archetype.

Because of the many sites on the body from which sepsis can originate, there are a number of symptoms. The most prominent are: Fast heart rate Fever or hypothermia (very low body temperature) Shaking or chills Warm or clammy/sweaty skin Confusion or disorientation Hyperventilation (rapid breathing) or shortness of breath Diagnosis and Tests

Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection (3). If not recognized early and managed promptly, it can lead to septic shock, multiple organ failure and death. It is most frequently a serious complicationof infection, particularly in low- and middle-income countries where it represents a major ca...
Anyone affected by an infection, severe injury, or serious non-communicable disease can progress to sepsis but vulnerable populations are at higher risk (4) including: 1. older persons, 2. pregnant or recently pregnant women, 3. neonates, 4. hospitalized patients, 5. patients in intensive care units, 6. people with HIV/AIDS, 7. people with liver ci...
Sepsis is a medical emergency and can present with various signs and symptoms at different times. Warning signs and symptoms include: 1. fever or low temperature and shivering, 2. altered mental status, 3. difficulty breathing/rapid breathing, 4. increased heart rate, 5. weak pulse/low blood pressure, 6. low urine output, 7. cyanotic or mottled ski...
In 2017, the largest contributors to sepsis cases and sepsis-related mortality across all ages were diarrhoeal diseases (9.2 to 15 million annual cases) and lower respiratory infections (1.8-2.8 million annually) (1). However, non-communicable diseasesare on the rise; one-third of sepsis cases and nearly half of all sepsis-related deaths in 2017 we...
Identifying and not underestimating the signs and symptoms listed above, along with the detection of some biomarkers (such as C reactive protein and procalcitonin), are crucial elements for early diagnosis of sepsis and the timely establishment of itsappropriate clinical management. After early recognition, diagnostics to help identify a causal pat...
Sepsis is a significant cause of maternal, neonatal and child mortality. Consequently, combating sepsis will contribute to achievement of Sustainable Development Goals (SDGs) targets 3.8 on quality of care, and 3.1 and 3.2by improving mortality rates in these vulnerable populations. Sepsis can also ultimately lead to death in patientsaffected by HI...
To combat this important global health threat, WHO responded with a WHO Secretariat Report and, in May 2017, the Seventieth World Health Assembly adopted Resolution WHA70.7 on Improving the prevention, diagnosis and clinical management of sepsis.The key pillars of Resolution WHA 70.7 are to: 1. Develop WHO guidance on sepsis prevention and manageme...
