Early-onset neonatal sepsis is found to be 0.77 to 1 per 100,000 live births in the U.S. In premature babies, the incidence and mortality rates are higher due to the weakness of their immune system. For infants with low birth weight, cases of early-onset sepsis is found to be about 26 per 1,000 and 8 per 1,000 live births.
Prematurity, low birth weight, chorioamnionitis, maternal urinary tract infection and/or maternal fever are complications that increase the risk for early-onset sepsis. Early onset sepsis is indicated by serious respiratory symptoms. The infant usually develops pneumonia, hypothermia, or shock. The mortality rate is 30 to 50%. [30]
The pathophysiology of septic shock is not entirely understood, but it is known that a key role in the development of severe sepsis is played by an immune and coagulation response to an infection. Both pro-inflammatory and anti-inflammatory responses play a role in septic shock. [ 8 ]
The SOFA scoring system is useful in predicting the clinical outcomes of critically ill patients. [8] According to an observational study at an Intensive Care Unit (ICU) in Belgium, the mortality rate is at least 50% when the score is increased, regardless of initial score, in the first 96 hours of admission, 27% to 35% if the score remains unchanged, and less than 27% if the score is reduced.

A follow-up conference, therefore, decided to define the patients with a documented or highly suspicious infection that results in a systemic inflammatory response as having sepsis. [18] Note that SIRS criteria are non-specific, [ 18 ] and must be interpreted carefully within the clinical context.
Relatively common causes include sepsis, surgery, major trauma, cancer, and complications of pregnancy. [1] Less common causes include snake bites, frostbite, and burns. [1] There are two main types: acute (rapid onset) and chronic (slow onset). [1] Diagnosis is typically based on blood tests. [2]
Others – Fungal and mycobacterial infections are rare causes of septic arthritis and usually have a slow onset of joint symptoms. Mycobacterial joint infection most commonly affects hip and knee joints, caused by reactivation of past mycobacterial infections, with or without signs and symptoms of tuberculosis in lungs.
The development of sepsis is primarily due to two scenarios. When there is an incomplete abortion caused by the pathogens that result in products of conception remaining in the body. The second scenario occurs intentional septic procedures leads to the spread of the infection from the placenta or fetus to the uterus; this can subsequently cause ...
