The relationship between premature rupture of the membranes and sepsis in preterm neonates

This investigation was designed as a hospital-based, historical cohort study. The objective of the study was to determine the association between premature rupture of the membranes (PROM) and its duration on neonatal sepsis, infection, and mortality. Neonates born alive with gestational ages between 25 and 35 weeks from singleton pregnancies complicated by PROM were selected. Each of the 507 neonates was matched on gestational age, gender, ethnicity, and month of birth with a neonate without the complication of PROM.^ Data were abstracted from deliveries between January 1979 and December 1985 describing the mother's demographics, labor and delivery treatments and complications, the neonate's demographics, infection status, and medical care. The matched pairs analysis reveals a significant increase in risk of neonatal sepsis (RR = 3.5) and neonatal infection (RR = 2.4) among preterm births complicated by PROM, with a PROM exposure contributing an excess 4 to 5 cases of sepsis per 100 infants (RD = 0.04 for infection and RD = 0.05 for sepsis). Generally PROM remains an important risk factor for sepsis and infection when controlling for various other characteristics, and the risk difference remains constant.^ PROM was not significantly associated with neonatal mortality (RR = 1.02). There is an increase in risk difference for mortality associated with PROM among septic and infected infants, but it is not significant.^ A clear increase in risk of sepsis and infection from PROM occurs when durations of PROM are long (more than 48 hours), e.g., for sepsis the RR is 2.42 for short durations and RR is 6.0 for long durations. No such risk with long duration appears for neonatal mortality.^ This study indicates the importance of close observation of neonates with PROM for sepsis and infection so treatment can be initiated early. However, prematurity is the major risk for sepsis and the practice of early delivery to avoid prolonged durations of PROM does not alter the magnitude of risk. The greatest protection against these infection complications was provided when the neonate weighed over 1500 grams or had more than 33 weeks gestation. ^

Prediction of sepsis in the burn intensive care unit patient

Sepsis is a significant cause for multiple organ failure and death in the burn patient, yet identification in this population is confounded by chronic hypermetabolism and impaired immune function. The purpose of this study was twofold: 1) determine the ability of the systemic inflammatory response syndrome (SIRS) and American Burn Association (ABA) criteria to predict sepsis in the burn patient; and 2) develop a model representing the best combination of clinical predictors associated with sepsis in the same population. A retrospective, case-controlled, within-patient comparison of burn patients admitted to a single intensive care unit (ICU) was conducted for the period January 2005 to September 2010. Blood culture results were paired with clinical condition: "positive-sick"; "negative-sick", and "screening-not sick". Data were collected for the 72 hours prior to each blood culture. The most significant predictors were evaluated using logistic regression, Generalized Estimating Equations (GEE) and ROC area under the curve (AUC) analyses to assess model predictive ability. Bootstrapping methods were employed to evaluate potential model over-fitting. Fifty-nine subjects were included, representing 177 culture periods. SIRS criteria were not found to be associated with culture type, with an average of 98% of subjects meeting criteria in the 3 days prior. ABA sepsis criteria were significantly different among culture type only on the day prior (p = 0.004). The variables identified for the model included: heart rate>130 beats/min, mean blood pressure<60 mmHg, base deficit<-6 mEq/L, temperature>36°C, use of vasoactive medications, and glucose>150 mg/d1. The model was significant in predicting "positive culture-sick" and sepsis state, with AUC of 0.775 (p < 0.001) and 0.714 (p < .001), respectively; comparatively, the ABA criteria AUC was 0.619 (p = 0.028) and 0.597 (p = .035), respectively. SIRS criteria are not appropriate for identifying sepsis in the burn population. The ABA criteria perform better, but only for the day prior to positive blood culture results. The time period useful to diagnose sepsis using clinical criteria may be limited to 24 hours. A combination of predictors is superior to individual variable trends, yet algorithms or computer support will be necessary for the clinician to find such models useful. ^

Pharmacological activation of endogenous protective pathways against oxidative stress under conditions of sepsis

Prevention of lymphocyte cell death in sepsis improves survival in mice

Sepsis induces extensive lymphocyte apoptosis, a process which may be beneficial to host survival by down-regulating the inflammatory response or, alternatively, harmful by impairing host defenses. To determine the beneficial vs. adverse effects of lymphocyte apoptosis in sepsis, we blocked lymphocyte apoptosis either by N-benzyloxycarbonyl-Val-Ala-Asp(O-methyl) fluoromethyl ketone (z-VAD), a broad-spectrum caspase inhibitor, or by use of Bcl-2 Ig transgenic mice that selectively overexpress the antiapoptotic protein Bcl-2 in a lymphoid pattern. Both z-VAD and Bcl-2 prevented lymphocyte apoptosis and resulted in a marked improvement in survival. z-VAD did not decrease lymphocyte tumor necrosis factor-α production. Considered together, these two studies employing different methods of blocking lymphocyte apoptosis provide compelling evidence that immunodepression resulting from the loss of lymphocytes is a central pathogenic event in sepsis, and they challenge the current paradigm that regards sepsis as a disorder resulting from an uncontrolled inflammatory response. Caspase inhibitors may represent a treatment strategy in this highly lethal disorder.
