Differentiation between biliary atresia, biliary hypoplasia and severe neonatal hepatitis continues to require direct visualization of the biliary ducts. This is usually accomplished by operative cholangiography using radiographic contrast material. Recently, we have employed an alternate technique of operative cholangiography using methylene blue. This method identifies patent biliary ducts by direct visualization. Methylene blue cholangiography (MBC) has been used in 16 infants with severe obstructive jaundice. In contrast to the radiopaque cholangiogram, MBC more accurately demonstrated biliary hypoplasia in two patients. In addition to the better resolution obtained by MBC, it can be performed in considerably less time than that usually required for x-ray cholangiography.

Two different virus inactivated plasma preparations are available in Germany. Methylene blue ephotoxidized (MB) plasma is plasma from a single donation, which is photoxidized using 1 microM methylene blue and visible light (1 hour 60,000 Lux). Photochemical inactivation reduces HIV by at least 5 log10, but also fibrinogen is altered. To date, the clinical significance of this finding is still unclear, since prospective clinical studies are lacking. Solvent detergent (SD) plasma is manufactured from a pool of about 2000 plasma donations, and triton-X-100 and tri-n-butyl-phosphate (TNBP) are added for virus inactivation. HIV and hepatitis viruses are thus reduced by 5 to 6 log10. SD treatment reduces protein S and alpha-2-antiplasmin by about 40%. Clinical studies have already demonstrated, that SD plasma is comparable with untreated, native fresh frozen plasma in terms of efficacy.
