Neonatal sepsis can be a life-threatening complication in preterm neonates. We present the clinical course of 3 preterm neonates, 1 with recurrent sepsis and 2 with late onset sepsis attributed to ingestion of breast milk containing pathogenic organisms. Breast milk should be considered as a potential source of infection in neonates with recurrent infections or when infections occur simultaneously in siblings.

The purpose of this study was to determine the short-term outcome of newborns less than 30 weeks gestation when there is definite placental histologic chorioamnionitis. A retrospective analysis was performed of records of all neonates delivered at our institution from January 1989 through January 1999. This information was retrieved from our perinatal database and pathology database. The population was stratified according to the presence or absence of histologic chorioamnionitis. Statistical analysis was performed using student t-test and Mann-Whitney method. Logistic regression was used to control for potential confounding variables. There were 392 neonates less than 30 weeks gestation delivered during this time period. Complete placental histology was available for 342 patients (87.4%). Histologic chorioamnionitis was identified in 140 (40.9%) cases. Those with histologic chorioamnionitis delivered sooner (26.3 versus 27.5 weeks), were of lower birth weight (920.1 versus 1029.8 g), and had lower 5-minute Apgarscores. Neonatal septicaemia and pneumonia were strongly associated with underlying histologic chorioamnionitis. There was a significant reduction in the incidence of respiratory distress syndrome (RDS) when histologic chorioamnionitis was present. Severe histologic chorioamnionitis increases the risk of premature delivery and is strongly associated with neonatal sepsis. There is a significant reduction in the incidence of RDS and neonatal mortality.

Neonatal sepsis is a leading infectious cause of infant mortality. While use of intrapartum antibiotic prophylaxis in the United States has led to dramatic declines in perinatal sepsis caused by the bacteria group B streptococcus, interventions to prevent perinatal sepsis due to other causes have not yet been clearly defined. This article synthesizes information on neonatal sepsis disease burden, trends, and risk factors and reviews current and potential approaches to neonatal sepsis prevention.

We evaluated all fatal neonatal sepsis and pneumonia cases occurring in Alaska during 1992-2000. Risk factors were evaluated using a database of all births occurring during the study period. Of 32 cases, group B streptococcus (GBS) was isolated from 21% (all 7 days of age), non-GBS Gram-positive bacteria from 50% (53% <7 days of age), and Gram-negative infections from 38% (58% <7 days of age). Infants born at <37 weeks gestation accounted for 72% of cases and had an increased risk of GBS [rate ratio (RR) 9.1, 95% confidence interval (CI) 2.0-41] and non-GBS (RR 40, 95% CI 16-101) disease. Neonatal sepsis mortality has become an outcome concentrated among pre-term infants. Aetiologies include GBS during the early neonatal period, Candida spp. during the late neonatal period, and other bacteria during both periods.

Neonatal sepsis is one of the major health problems throughout the world. Every year an estimated 30 million newborns acquire infection and 1-2 million of these die. The present review provides updates regarding neonatal sepsis to help paediatricians to protect the newborn from this deadly problem. The onset of sepsis within first 48 hours of life (early onset sepsis) is frequently associated with pre and perinatal predisposing factors while onset after 48-72 hours of life (late onset sepsis) frequently reflects infection acquired nosocomially. Some literatures say that early onset disease presents in the first 5-7 days of life. Klebsiella pneumoniae is the leading pathogen causing neonatal sepsis in Bangladesh and neighbouring countries. Among many risk factors the single most important neonatal risk factor is low birth weight. Other main risk factors are invassive procedures in the postnatal period and inadequate hand washing before and after handling babies. Sepsis score is a useful method for early and rapid diagnosis of neonatal sepsis which was developed by Tollner U in 1982. Antibiotics should be given to most of the neonates suspected of infection. Ampicillin and gentamicin are the first drug of choice. In Bangladesh context sepsis score may be used as a good parameter for the early and rapid diagnosis of sepsis and that will guide the treatment plan. Clean and safe delivery, early and exclusive breastfeeding, strict postnatal cleanliness following adequate handwashing and aseptic technique during invasive procedure might reduce the incidence of neonatal sepsis. Prompt use of antibiotic according to standard policy is warranted to save the newborn lives from septicaemia.

Neonatal septicemia acquired by vertical transmission of Pasteurella multocida is very rare. The authors report a case of Pasteurella multocida septicemia in a 2-day-old male infant. His mother had a history of prolonged premature rupture of membranes and subsequently developed fever. The patient had fever and lethargy at 36 hours of age, then developed severe pneumonia, sepsis, persistent pulmonary hypertension, renal failure and liver failure. Although the appropriate antibiotics were given, he continued to deteriorate and eventually died.

Neonatal sepsis still remains as one of the actual problems in modern medicine due to its high morbidity and mortality rates determined by diagnostic difficulties and absence of sufficient evidence for effective therapy. Literature data have shown that essential role in pathogenesis of sepsis belongs to the cellular oxidation-reduction misballance and development of the oxidative stress. The aim of our work was to assess indices of pro- and antioxidant systems in term neonates with sepsis on the background of anemia and without it. A total of 41 neonates (17 male, 24 female) with the age range from 3 to 7 days, with early sepsis, and in 2003-2005 years treated at the department of neonates' therapy and intensive care unit of pediatric clinics of the Tbilisi State Medical University were under observation. The control group involved 17 practically healthy neonates of the same age range. In consequence of the analyses there was ascertained, that with anemia increases intensification free-radical oxidation process. At the same time, antioxidant system activity was not change significantly in the sepsis with anemia, than other one. Pathogenesis of anemia may was founded undergo hemolitic anemia results by oxidative stress. According to the results of investigations could be concluded that in case of anemia developed at neonatal sepsis supports intensify of oxidative stress and at the same time anemia is the result of the oxidative stress.

Neonatal sepsis is a significant cause of morbidity and mortality in the neonatal intensive care unit. The epidemiology of neonatal infections is complex; however, they are in large part secondary to developmentally immature host defence mechanisms. These immunodeficiencies, which are exaggerated in premature and sick neonates, include quantitative and qualitative deficits in phagocytes, complement components, cytokines and immunoglobulins. Therapies that modulate or augment host defences may attenuate the virulence of neonatal infections. In this paper, we have reviewed immunotherapies that modulate the immune system of the neonate, including intravenous immunoglobulins and myeloid haematopoietic growth factors. Future studies should focus on investigating other abnormalities of neonatal host defence and/or combined immunotherapy approaches in an attempt to circumvent the immaturity of host defence and potentially reduce both the incidence and severity of neonatal sepsis.

Neonatal sepsis is a life-threatening emergency, and any delay in treatment may cause death. Because of the importance of the problem in Iran, the aim of this retrospective study was to determine the etiological agents of neonatal septicemia, and the prevalence and epidemiology of Klebsiella bacteremia in the neonatal wards. Two hundred and ten cases of neonatal sepsis occurred during the study period. The most common organism was coagulase-negative staphylococci. Gram-negative organisms were isolated in 66 cases (31.43%), and the most common Gram-negative organism causing neonatal sepsis was Klebsiella pneumoniae. The mortality rate due to Gram-negative bacteria including K. pneumoniae was higher than that due to other bacteria. The distribution of the main pathogens is different in the Azerbaijan state, northwest of Iran, and K. pneumoniae is predominant, but Streptococcus agalactiae plays a relatively minor role in the etiology of sepsis during the first month of life.

Neonatal sepsis occurs from 1 to 21 newborns out of 1 000 live births with mortality rates as high as 30% up to 69%. The most important risk factors are prematurity, low birth weight, invasive medical procedure and prolonged hospitalization in neonatal intensive care units. An aimed and restrictive antibiotic therapy has an outstanding importance to reduce both morbidity-mortality rates and multiple drug-resistance. Generally, preterm newborns present nonspecific clinical signs of infection. The use of high sensitivity infection markers and a negative predictive value (near 100%) are important to distinguish infected and noninfected patients before the culture results and to verify adequacy and duration of antibiotic therapy. This article reviews the immunologic function and practical use of C reactive protein (CRP) and other markers in the diagnosis of neonatal sepsis. While CRP is a specific late infection marker, cytokines, cell surface markers and procalcitonin (PCT) are early infection markers. The use of multiple markers as CRP, PCT, IL-6, IL-8, CD64, CD11b is useful both to early (24-48 h) diagnose of neonatal sepsis, and to monitorate the antibiotic treatment while waiting for the results of cultural examinations.
