[Arguments for an infectious cause of IUGR]. / Quels arguments pour déterminer l'origine infectieuse d'un retard de croissance intra-utérin?

Intra-uterine growth retardation (IUGR) is a frequent cause of consultation in antenatal care unit. The prognosis relies on the etiology: vascular, chromosomic, genetic, or infectious. Because of chronic fetal distress, hypotrophy increase morbidity, mortality and neurosensorial long term effect. Usually, infection is involved in 5 to 15% of the IUGR, mainly by Cytomegalovirus (CMV), Varicella Zoster virus, rubella, toxoplasmosis, herpes and syphilis. Maternal sera and amniotic liquid analysis make the diagnosis possible but fetal ultrasound scan is used to find other features. Most of the abnormalities are unspecific but their combination can worsen fetal prognosis. Infection should always be ruled out in the assessment of IUGR.

[Infection epidemiological data among blood donors in Germany 2003-2004. Report of the Robert Koch Institute in accordance with Article 22 of the Transfusion Act]. / Infektionsepidemiologische Daten von Blutspendern 2003-2004. Bericht des Robert Koch-Instituts zu den Meldungen nach [section sign] 22 Transfusionsgesetz.

The Robert Koch Institute collects and evaluates data on the prevalence and incidence of HIV, hepatitis C (HCV), hepatitis B (HBV) and syphilis infections among blood and plasma donors in Germany in accordance with Article 22 of the Transfusion Act. This surveillance permits an assessment of the occurrence of infections in the blood donor population and consequently the safety of the collected donations. This report includes data from all blood donation services in Germany for 2003 and 2004. Altogether 7.09 million and 6.37 million donations or blood samples from prospective donors were screened in 2003 and 2004, respectively. In 2003 the prevalence rates of the relevant infections (per 100,000 donations) were 8.2 for HIV, 99.3 for HCV, 158.9 for HBV and 34.4 for syphilis. In 2003 the rates of seroconversion (per 100,000 donations) were 0.8 for HIV, 1.2 for HCV, 1.0 for HBV and 1.5 for syphilis in 2003. In 2004 the prevalence rates (per 100,000 donations) were 4.8 for HIV, 85.3 for HCV, 156.3 for HBV and 36.8 for syphilis. In 2004 the rates of seroconversion (per 100,000 donations) were 0.9 for HIV, 1.3 for HCV, 0.6 for HBV and 2.0 for syphilis. The analysis showed a very low incidence of infections with a decreasing trend for HCV infections and an increase in HIV and syphilis infections. The latter needs to be monitored carefully and possible causes evaluated. The quality of the reported data has improved compared to previous years. Still, some problems remain with the differentiation of the data according to sex, age and interdonation interval as well as reporting by individual blood donation centres as required by the Transfusion Act.
