Plasma levels of interleukin-6 and interleukin-10 in preterm neonates evaluated for sepsis

In a prospective study, plasma interleukin-6 (IL-6) and interleukin-10 (IL-10) levels were measured by enzyme-linked immunosorbent assay in 45 premature neonates (25–34 weeks gestational age) with signs and symptoms of suspected sepsis at 0, 12 and 24 h; C-reactive protein (CRP) was measured at 0–24 h after enrolment. Six subjects were excluded due to insufficient blood sampling. The remaining 39 neonates were assigned to one of three groups: 25 newborns with sepsis (blood culture positive), seven with pneumonia (positive results on broncho-alveolar lavage fluid culture and characteristic chest radiography) and seven with necrotising enterocolitis (NEC) (characteristic intestinal and radiological signs according to the criteria of Bell et al.). A group of 20 healthy preterm neonates represented control subjects. On admission, higher levels of IL-6, IL-10 and CRP were observed in neonates with sepsis: IL-6 (median 1500 pg/ml, range 487–10000 pg/ml), IL-10 (median 113 pg/ml, range 70–196 pg/ml), CRP (median 22 mg/l, range 4–80 mg/l); pneumonia: IL-6 (median 1500 pg/ml, range 747–8000 pg/ml, IL-10 (median 84 pg/ml, range 76–92 pg/ml), CRP (median 10 mg/l, range 8–33 mg/l) and NEC: IL-6 (median 6650 pg/ml, range 1595–7950 pg/ml), IL-10 (median 80 pg/ml, range 61–147 pg/ml), CRP (median 3 mg/l, range 2.8–8 mg/l) as compared to controls (IL-6 median 208 pg/ml, range 198–349 pg/ml; IL-10 median 36 pg/ml, range 19–50 pg/ml; CRP median <2 mg/l) (P < 0.05). In neonates with sepsis, IL-6 levels were significantly correlated with IL-10 levels (r=0.65; P=0.04) at the time of the second sample. The highest IL-6 levels were observed at onset, while IL-10 was predominant 12 h later. On admission, IL-10 and CRP levels were significantly higher in non-survivors (IL-10 median 507 pg/ml, range 422–753 pg/ml; CRP median 123 mg/l, range 20–219 mg/l) than in survivors (IL-10 median 76 pg/ml, range 61–143 pg/ml; CRP median 8 mg/l range 3–46 mg/l), while IL-10 levels were significantly higher (P < 0.05) also 12 h after admission (non-survivors: IL-10 median 600 pg/ml, range 538–800 pg/ml; survivors: IL-10 median 74 pg/ml, range 53–161 pg/ml). IL-6 and IL-10 levels were significantly correlated with CRP levels on admission (r=0.45; P=0.05). Conclusion Preterm neonates with sepsis, pneumonia or necrotising enterocolitis showed increased interleukin-6, interleukin-10 and C-reactive protein levels. High interleukin-10 concentration was associated with mortality and could be an early indicator of prognosis. Received: 21 November 2000 / Accepted: 23 January 2001     

Serum interleukin-1β in neonatal sepsis

Serum levels of interleukin-1β (IL-1β) in newborn infants with septicaemia were measured and possible relationships between the clinical course of the infants, causative micro-organisms and IL-1β levels were investigated in a prospective study. The study groups comprised 49 newborn infants (25 mature, 24 premature) with proven sepsis and 40 healthy newborn infants (20 mature, 20 premature). Serum IL-1β levels were measured using the IL-1β immunoradiometric assay. The levels were found to be lower in neonates with sepsis (median 0.1 pg/ml) than in healthy controls (median 27.9 pg/ml) ( p <0.001). Non-significant trends towards lower levels were observed in children with shock and in non-survivors. No correlation was found between IL-1β and postnatal age, gestational age or the study weight of the patients. There was no significant difference in the serum IL-1β level in septic patients infected with Gram-positive bacteria and those infected with Gram-negative bacteria. The results show that the concentration of IL-1β is significantly decreased in preterm and term neonates with sepsis.     

Inflammatory mediators in umbilical plasma from neonates who develop early-onset sepsis

OBJECTIVES: To study whether early-onset neonatal sepsis is associated with a prenatal immune response with elevated umbilical plasma levels of inflammatory mediators, and to study whether mediator levels may be helpful in identifying infected neonates. SETTING: Nested case-control study. METHODS: Cord blood was sampled from 7,073 consecutively delivered neonates. After review of the medical records, neonates suspected to suffer from infection were classified as infected (n = 52) or noninfected but sick controls (n = 33). We also included a group of healthy controls (n = 99). Umbilical plasma levels of tumour necrosis factor-alpha (TNFalpha), interleukin (IL)-1beta, IL-6, IL-8, soluble TNF receptors (p55 and p75), IL-1 receptor antagonist (IL-1RA) and C-reactive protein were measured by immunoassays. RESULTS: Infected neonates had higher levels of TNFalpha, IL-1beta, IL-6, IL-8, p55, p75 and IL-1RA than healthy controls (all p < 0.01). Among preterm infants (GA <37 weeks), those with infection (n = 11) had higher levels of IL-1beta, IL-6, IL-8, p55 and p75 than noninfected sick controls (n = 13) (all p < 0.05), but among term infants, the infected did not differ from the noninfected sick controls. Receiver operator characteristic plots showed that IL-1beta, IL-6 and IL-8 identified preterm infected neonates accurately. CONCLUSIONS: Early-onset neonatal sepsis is associated with a prenatal immune response with increased TNFalpha, IL-1beta, IL-6, IL-8, p55, p75 and IL-1RA levels in umbilical plasma. Among neonates who present symptoms suggestive of infection, cytokine levels may be helpful in identifying preterm, but not term infected individuals.

Increased serum IL-10/IL-12 ratio in wheezing infants

To investigate the association between various serum markers and atopic symptoms in the first year of life, and to evaluate the prognostic value of these markers for the development of wheezing and skin rash in the second year of life. Data of 86 children on the development of wheezing and skin rash in the first 2 years of life were collected prospectively, making use of parental completed questionnaires, weekly symptom cards, structured interview and physical examination. Serum markers (IL-10, IL-12, IL-13, eotaxin, sE-selectin, sICAM-1, sIL-2R) and total and specific IgE were determined at age 1. Children who developed wheezing in the first year of life had lower serum levels of IL-12 than children without symptoms (median 40.3 pg/ml vs. 49.0 pg/ml, p = 0.01) and a higher serum IL-10/IL-12 ratio (0.41 vs. 0.31, p = 0.001) at age 1. The IL-10/IL-12 ratio increased with an increasing number of wheezing episodes. Levels of sE-selectin in children with wheezing and in children with itchy skin rash in the first year of life were higher than in symptom free children (6.1 ng/ml and 5.9 ng/ml vs. 4.9 ng/ml, p = 0.01 and p = 0.03, respectively). Children who developed wheezing in the second year of life already had increased sICAM-1 levels at age 1. Children who developed wheezing in the first year of life showed a serum cytokine response that is skewed towards a T-helper 2 profile, with lower IL-12 levels and an increased IL-10/IL-12 ratio. Children who developed wheezing in the second year of life had elevated sICAM-1 levels at age 1. Follow-up of the children is needed to evaluate the prognostic value of various serum markers for the development of allergic disease in later childhood.     

Cord blood levels of cytokines as predictors of early neonatal sepsis

AIM: To investigate whether cord blood levels of C-reactive protein, interleukin-1beta, interleukin-6, interleukin-8, tumour necrosis factor-alpha and the soluble receptor of interleukin-2, are useful markers in the diagnosis of early neonatal sepsis. DESIGN: Umbilical cord blood samples were obtained at birth from 261 neonates, but 5 of these newborns were excluded from the study. Group I included 10 newborns that developed early neonatal sepsis with a positive blood culture; Group II included 11 newborns with non-infectious perinatal diseases; Group III, which served as the control group, included 10 randomly selected patients, matched for gestational age, among the 235 healthy newborn babies. RESULTS: There were no differences among the three study groups in levels of C-reactive protein. interleukin-1beta, tumour necrosis factor-alpha and the soluble receptor of interleukin-2. Interleukin-6 was significantly elevated in Group I (360.4+/-157.8 pg/ml) and Group II (158.8+/-122.3 pg/ml), when compared with Group III (8.6+/-3.12 pg/ml) (p < 0.01), whereas interleukin-8 was significantly elevated in Group I (389.3+/-115.9 pg/ml) compared with Groups II (30.2+/-5.1 pg/ml) (p < 0.05) and III (33.9+/-8.6 pg/ml) (p < 0.05). A cut-off of 100.8 pg/ml for interleukin-6 obtained by the ROC (receiver operating characteristic) method gave a sensitivity of 50% and a specificity of 87%, and a cut-off of 111.7 pg/ml for interleukin-8 showed a sensitivity of 78% and a specificity of 91%. CONCLUSION: While cord blood levels of interleukin-6 appear to be related to pathological conditions in the perinatal period (infectious and non-infectious), interleukin-8 seems to be a good predictor of early bacterial neonatal infection.
