Hepatic injury and
pancreatitis during treatment with serotonin reuptake inhibitors: data
from the World Health Organization (WHO) database of adverse drug
reactions.

Severe
hepatic adverse drug reactions have been occasionally reported in the
literature for the selective serotonin reuptake inhibitors (SSRIs),
venlafaxine and nefazodone. In addition, a few case reports have
suggested a possible association between SSRI treatment and
pancreatitis. To further investigate this issue, a Bayesian confidence
propagation neural network (BCPNN) method was applied on the World
Health Organization database of adverse drug reactions. This method
identifies whether a drug/adverse drug reaction combination is reported
more frequently to the database than expected on the basis of chance
alone compared to general reporting in the database. A statistically
significant unexpected high number of reports were found for nefazodone
and hepatic injury, relative to the generality of the dataset but, for
the other drug/adverse drug reaction combinations, no such association
was found. The nefazodone finding is in accordance with data from other
publications, suggesting that the risk of hepatic injury is increased.
However, because of the nature of the BCPNN, the negative findings do
not necessarily prove that there is no excess risk for hepatic
injury/pancreatitis during treatment with drugs other than nefazodone.
Further studies are required using alternative methodologies to
demonstrate whether the selective serotonin reuptake inhibitors or
venlafaxine may cause hepatic injury or pancreatitis.
