Abstract We evaluated a new rapid semi-quantitative immunometric assay of C-reactive protein (CRP) as a screening test for sepsis by comparison with an automated nephelometric method. Plasma samples (n = 101) from preterm infants during the first week of life were saved for CRP analyses. We measured CRP by the Nycocard semiquantitative method and compared the results with those obtained with a Behring Nephelometer. A CRP value less than 10 mg/L was considered to be negative for infection. All CRP results read as less than 10 mg/L (negative) by the Nycocard method were also less than 10 mg/L by the comparison method, and all CRP values found to be greater than 20 mg/L (positive) by the Nycocard method were also positive by the comparison method. Results in the 10-20 mg/L range were considered equivocal. We conclude that the Nycocard CRP semi-quantitative method is a rapid and useful screening test for sepsis in preterm infants.

ABSTRACT C-reactive protein (CRP) is a normal constituent of human sera synthesized by hepatocytes and induced by proinflammatory cytokines. The function of this acute-phase reactant includes activation of complement and enhancement of opsonophagocytosis. CRP binds to phosphorylcholine (ChoP), a constituent of eukaryotic membranes that is also found on the cell surface of major bacterial pathogens of the human respiratory tract, including Streptococcus pneumoniaeand Haemophilus influenzae. The presence of CRP on mucosal surfaces and role in innate immunity in the human respiratory tract where ChoP-containing organisms reside have not been previously studied. We have shown using a monoclonal antibody to CRP that CRP is present in inflamed (0.17 to 42 μg/ml) and uninflamed (<0.05 to 0.88 μg/ml) secretions from the human respiratory tract in sufficient quantities for an antimicrobial effect. In addition, the CRP gene was expressed in epithelial cells of the human respiratory tract using in situ hybridization on nasal polyps and reverse transcriptase PCR of pharyngeal cells in culture. The complement-dependent bactericidal activity of normal nasal airway surface fluid and sputum against ChoP-expressing H. influenzae was abolished when the secretions were pretreated to remove CRP. In summary, the results indicate that CRP is present in secretions of the human respiratory tract, that human respiratory epithelial cells are capable of CRP expression, and that this protein may contribute to bacterial clearance in the human respiratory tract.

Abstract Objective: The Japanese Midwifery Association (JMA) guidelines allow midwives to handle group B Streptococcus (GBS)-positive women during pregnancy and labour at maternity homes. However, there are no guidelines to manage neonates born to GBS-positive women in Japan. We aimed to investigate the opinions of paediatricians regarding optimal management strategies for neonates born to GBS-positive women in maternity homes. A questionnaire was sent to paediatricians at 396 Japanese perinatal medical centres. We examined opinions regarding examinations and routine clinical tests for neonates born to GBS-positive women in maternity homes. Results: Of 235 paediatricians, only 11.2% considered that paediatric examinations were unnecessary for neonates born to GBS-positive women in maternity homes. Moreover, 20.5%, 13.2%, and 11.1% of paediatricians considered culture test of the nasal cavity, serum C-reactive protein level analysis, and blood cell count analysis, respectively, necessary for neonates born to GBS-positive pregnant women with intrapartum antibiotic prophylaxis (IAP); 36.3%, 56.2%, and 40.6% of paediatricians considered these tests necessary in cases without IAP. The JMA guidelines had low penetration rates among paediatricians in Japan. To manage neonates of GBS-positive women in maternity homes, midwives should engage with commissioned paediatricians in more detail and develop appropriate strategies to increase awareness and cooperation.
