Przeprowadzono oznaczenie endotoksyny testem LAL w szczepionkach polisacharydowych przeciw Haemophilus influenzae skoniugowanych z toksoidami Te lub Di (Act-Hib, Hiberix, Hib-TITER). W szczepionce Act-Hib stwierdzono poziom endotoksyny x=110 EU/ml, w Hiberix x=1,51 EU/ml i w Hib-TITER x=2,4 EU/ml. Stwierdzono zależność zawartości endotoksyny w badanych szczepionkach polisacharydowych od wielkości wielocukru PRP (fosforan-ribozylo-rybitolu) oraz od zawartości endotoksyny w komponencie białkowej.

Quantitative evaluation of bacterial endotoxin was performed in the following vaccines: Act-Hib, Hiberix, Hib-Titer. The aim of this study was to assess the accuracy and precision of chromogenic LAL test with S-2423 substrate for this particular biopreparations and after that to determine the amounts of endotoxin as a factor of vaccine safety. Because of the lack of information concerning the presence of endotoxin in Act-Hib vaccine, we also tried to establish the limits for the presence of endotoxin in this type of vaccine. The estimated level of endotoxin was as follows: 110 EU/ml in Act-Hib, 1,64 EU/ml in Hiberix and 2,4 EU/ml in Hib-Titer. The results of this study showed that the amounts of endotoxin was dependent on the molecular size of polysacharide PRP and on the presence of protein component. The limit of endotoxin presence in Act-Hib vaccine recomended by us is max. 150 EU/ml.
