MOLECULAR DIAGNOSIS
The use of molecular biology techniques to diagnose new cases of sepsis is necessary.
This has been strongly en-couraged by the requirement of smaller samples, capable of providing reliable results
and earlier diagnosis.
These techniques can detect the presence of LPS in the blood,expression of High-Mobility Group Box (HMGB) -1
oreven identify bacterial DNA76.
These tests, however, arenot 100% accurate, but they do strongly indicate the pres-ence of sepsis.
Detection of bacterial DNA fragments byreal-time polymerase chain reaction (RT-PCR) in bloodsamples, or 16S rRNA
fragments of Gram-positive andGram-negative bacteria and Candida in the 18S rRNAmight be very promising to help
early detection of sepsis,since they have shown a high degree of specificity and sen-sitivity.
The main disadvantages of these techniques are the high costs, the lack of standardization, and the need for
skilled personnel to perform them.
The ideal test should be precise, affordable, reproducible, fast, and show high specificity and sensibility,
being able to accurately evaluate the patient during different stages of the condition. Until now, none of the
tests fulfilled these conditions.
SCORING PREDISPOSITION TO SEPSIS The criteria for diagnosis of sepsis was established in 1991,and revised only
at the International Sepsis DefinitionsConference in 200137.
The risk and individual symptomsduring sepsis were defined as PIRO: predisposition to in-fection and response to
organ dysfunction37,77. This scoreis important to establish a correct and personalized treat-ment implementation
in sepsis.
The PIRO score uses sev-eral indicators such as prior co-morbidities, gender, age,culture and characterization
of the sensitivity of the mi-croorganism, SIRS, manifestations of sepsis, shock, PCR,and failure rate of organ
dysfunction37.
Another widelyused diagnostic criterion is the age acute physiology andchronic health examination (APACHE)78-79,
but it is morerestricted and sometimes fails to differentiate sepsis fromSIRS. In addition, the information
obtained from themonitoring of indicators of severity (sepsis-related organfailure assessment – SOFA) may be
more appropriate inmany cases80.
CONCLUSION Rapid diagnosis is essential in the case of sepsis. Laboratory findings are important and represent
a two-sided pro-cess.
The first side is responsible for monitoring changes in metabolic homeostasis and patient evaluation; indicating
severity of the disease and whether there is involvement of specific organs or entire systems.
The second refers to pathogen identification through a microbiological screening of the patient.Several
indicators might be used for this purpose:pro-inflammatory mediators, acute phase indicators, and pathogen
metabolites. Lactate levels, serum cytokines,presence of colony stimulating factors, and plasma nitricoxide
levels may be early indicators of SIRS, but remain restricted to research units.
An ideal test should allow for a fast and precise diagnosis, be reproducible, affordable, and have high
sensitivity and specificity. Despite several candidates such as bloodculture, serum lactate, and PCT levels, a
combination of tests is still compulsory for the diagnosis of sepsis.
In a field where speed and accuracy are needed, a gold standard test for sepsis is still searched for. Because
health is so precious, knowledge must rise to meet current needs.
