Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Sepsis is a systemic inflammatory response syndrome caused by infection can lead to life threatening multi-organ dysfunction.

Septic shock causes circulatory and metabolic abnormalities, leading to increased mortality in hospitalized patients, especially in intensive care unit (ICU) patients.

Sepsis can affect the function and number of immune cells, including neutrophils, lymphocytes and monocytes.

Neutrophils play crucial roles in the innate cellular immune system. Early higher neutrophil counts correlated with increased sepsis severity.

In sepsis, lymphocytes decrease owing to the apoptosis mediated by innate response.

Reversily, number of neutrophils dramatically increase reflecting degree of inflammation.

The neutrophil-to-lymphocyte ratio (NLR) is a novel inflammatory biomarker that can be obtained through blood routine tests, it is cost- effective and widely available, and it is beneficial to the early recognition of poor prognosis in septic patients.

Albumin is a molecule that is the most abundant protein in plasma. For a variety of physiological mechanisms, albumin has a variety of function, including serving as a major buffer, extracellular antioxidant, immune modulator, antidote and transporter in plasma.

Increased capillary leakage of albumin is one of the features of SIRS. This means that lower albumin levels correlate with severe systemic inflammation and organ failure.

Hypoxia and tissue hypo perfusion seen in sepsis play a key role on the development of multi-organ failure in septic patients.

Lactic acidosis is one of the best indicators of the insufficient perfusion or development of anaerobic metabolism during septic shock.

The inability of liver to metabolize lactate as a result of the deterioration of liver perfusion also increases lactate levels.

The measurement of blood lactate levels used to determine tissue hypoxia is rapid, inexpensive and easy.

Because lactate and albumin levels progress differently as the development of sepsis proceeds, a ratio between the two rather than analyzing lactate and albumin alone may be a new and perhaps better indicator for the patient's prognosis.
