Sepsis is a highly inflammatory disorder with the presence of organ dysfunction in severe cases and mostly caused by bacterial infection (Bone et al., 1989). These obvious characteristics of the disease prompted galvanize the belief that inflammation solely was responsible for sepsis related mortality.
Sepsis occurs when your body develops overwhelming inflammation as a reaction to infection. The problems that develop with sepsis can affect multiple organs in the body. Sepsis can be life-threatening and requires prompt and skilled medical care.
What causes sepsis? Most sepsis is caused by bacterial infections, but it can also be caused by viral infections, such as COVID-19 or influenza; fungal infections; or noninfectious insults, such as traumatic injury.
Bacterial infections cause most cases of sepsis. Sepsis can also be a result of other infections, including viral infections, such as COVID-19 or influenza, or fungal infections.
During sepsis, systemic activation of the innate immune system by PAMPs and DAMPs results in a severe and persistent inflammatory response characterized by an excessive release of inflammatory cytokines such as IL-1, TNF, and IL-17, collectively known as the “cytokine storm”(30).

When inflammation happens, chemicals from your body's white blood cells enter your blood or tissues to protect your body from invaders. This raises the blood flow to the area of injury or infection. It can cause redness and warmth.
Sepsis can develop quickly from initial infection and progress to septic shock in as little as 12 to 24 hours. 1 You may have an infection that's not improving or you could even be sick without realizing it.
The condition can arise suddenly and progress quickly, and it's often hard to recognize. Sepsis was once commonly known as “blood poisoning.” It was almost always deadly. Today, even with early treatment, sepsis kills about 1 in 5 affected people.
However, there might be other symptoms related to sepsis based on where the infection is. Abdominal pain is one such symptom.
If you have sepsis, you already have a serious infection. Early symptoms include fever and feeling unwell, faint, weak, or confused. You may notice your heart rate and breathing are faster than usual. If it's not treated, sepsis can harm your organs, make it hard to breathe, and mess up your thinking.
High heart rate or weak pulse. Fever, shivering, or feeling very cold. Confusion or disorientation. Shortness of breath.
Sepsis is known as the 'silent killer' because its symptoms often mimic that of other illnesses such as the flu or gastro. But, if it is identified and treated early, patients can recover.
It's clear that sepsis doesn't occur without an infection in your body, but it is possible that someone develops sepsis without realizing they had an infection in the first place. And sometimes, doctors never discover what the initial infection was.
blue, grey, pale or blotchy skin, lips or tongue – on brown or black skin, this may be easier to see on the palms of the hands or soles of the feet. a rash that does not fade when you roll a glass over it, the same as meningitis. difficulty breathing, breathlessness or breathing very fast.
Severe breathlessness or sleepiness. It feels like you're going to die or pass out. Skin mottled or discoloured. An extremely high or a very low temperature; repeated vomiting; seizures; and a rash which doesn't fade when you press a glass against it are also possible 'red flags'.

Left unaddressed, chronic inflammation can damage healthy cells, tissues and organs, and may cause internal scarring, tissue death and damage to the DNA in previously healthy cells. Ultimately, this can lead to the development of potentially disabling or life-threatening illnesses, such as cancer or Type-2 diabetes.
Based on visual observation, the ancients characterised inflammation by five cardinal signs, namely redness (rubor), swelling (tumour), heat (calor; only applicable to the body' extremities), pain (dolor) and loss of function (functio laesa).
Inflammation is associated with diseases such as the following: Autoimmune diseases like rheumatoid arthritis. Cardiovascular diseases like high blood pressure and heart disease. Gastrointestinal disorders like inflammatory bowel disease.
A single diagnostic test for sepsis does not yet exist, and so doctors and healthcare professionals use a combination of tests and immediate and worrisome clinical signs, which include the following: The presence of an infection. Very low blood pressure and high heart rate. Increased breathing rate.
The LUCCAASS mnemonic will assist the search for source: lung (pneumonia), urine (cystitis/pyelonephritis), cardiac (endocarditis), CNS (meningitis, encephalitis), abdominal (abscess, cholecystitis), arthritis (septic arthritis), spine (osteomyelitis, abscess), and skin (cellulitis, IV line/PICC infection).
As severe sepsis usually involves infection of the bloodstream, the heart is one of the first affected organs.
As sepsis worsens or septic shock develops, an early sign, particularly in older people or the very young, may be confusion or decreased alertness. Blood pressure decreases, yet the skin is paradoxically warm. Later, extremities become cool and pale, with peripheral cyanosis and mottling.
