[Cytological-energetic principle of the amniotic fluid examination on female patients with diagnosis of preterm premature rupture of membranes - up to now experiences and perspectives].

In our study we have dealt with the amniotic fluid examination on female patients with diagnosis of preterm premature rupture of membranes (PPROM). For one of the most important task in the feto-maternal medicine we consider the discovered method of amniotic fluid examination which is capable of the earliest possible detection in an intraamniotic inflammatory response. Unnoticed could harm or in the most serious cases threat the life of fetus or its mother. This was also the main reason why we chose this topic for our study. We have not been interested only in already known interleu-kin-6 (IL-6), but we have approached the examination comprehensively. We used the cytological-energetic principle supplemented by the examination of aspartate-amino-transferase (AST), in which already are long-term experiences in investigating other extracellular fluids. We have monitored values of C-reactive protein (CRP) and leucocytes in maternal serum, IL-6, AST and energetic score ratio (KEB) in amniotic fluid. Further we have investigated which imunocompetent cells have been dominant in amniotic fluid at different types of inflamantory reaction. According to the results of the examination of the control groups, it was necessary to correct the KEB limit in comparison to KEB limits of other extracellular fluids. Although our study includes untill now only 44 patients - 21 controls and 23 investigated persons, we have been already able to find out some trends of changes in observed parametres. As a very impotant discovery we consider the fact, that KEB, AST and cytological examination of amniotic fluid seem to be the methods for prediction of chorioamnionitis as reliable as the examination of IL-6. These methods are besides less expensive and therefore more suitable for the use in the small hospitals and developing countries. We continue in our study to confirm the previously found trends on the larger numbers of patients.
