ABSTRACT

Costa Rica no es la excepción en cuanto a la prevalencia de ocratoxina A en plasma, ya que en este estudio se obtuvo la presencia de la micotoxina en el 95% de las 149 muestras estudiadas. También se estudió la presencia de la ocratoxina A en 110 muestras de diferentes marcas de café tostado y molido de las 12 torrefactoras más importantes del país y de 7 supermercados. A excepción de una muestra de café que dio resultados negativos, el resto de muestras analizadas presentaron la micotoxina en cantidades menores a 4000 ng/L o kg. Se trató de encontrar una asociación entre el consumo de café y la presencia de la ocratoxina A en el plasma así como del consumo de cerveza, sin embargo no hubo diferencia estadísticamente significativa en el valor promedio de la micotoxina entre los tomadores y no tomadores de café y tampoco entre los bebedores y no bebedores de cerveza.


Ocratoxin A in human plasma and coffee from Costa Rica by ELISA. Costa Rica is not an exception in the prevalence of ochratoxin A in human plasma, in this research the presence of the micotoxin was found in 95% of the 149 samples studied. The presence of ocratoxina A also was studied in 110 samples of toasted and grounded coffee from the most important 12 coffee factories of the country and from 7 supermarkets. With the exception of one negative sample the rest of them have concentrations of micotoxin below 4000 ng/kg. An association between the coffee consumption and the presence of ochratoxin A in plasma was attempted to be found as well as in the consumption of beer, but there were any statistically significant difference in the average level of mycotoxin between the coffee consumers and non coffee consumers neither between beer consumers and no beer consumers.

ABSTRACT

This study included 172 primigravid mothers, 98 had preeclampsia, 22 had eclamptic fits, and 52 were normal pregnants. Aflatoxins were detected in 70.4% and 90.9% in maternal blood samples of preeclamptic and eclamptic patients, respectively, compared with none in the control. They were detected in 67.3%, 90.95%, and 1.9% in the fetal blood of preeclamptic, eclamptic and control groups, respectively. There was no significant difference in Aflatoxins [Afs] between maternal and fetal blood. Ochratoxin A could not be detected in maternal blood of the control group or in the fetal blood samples of all groups. Aflatoxin B1 was the most abundant aflatoxin in the maternal and fetal blood samples. Aflatoxin M1 and M2 could not be detected in the umbilical cord blood samples. There was significant high level of AfB1 in the umbilical cord blood of unhealthy babies [small for date, neonatal distress and neonatal jaundice] compared with healthy babies
