摘要
Valproic acid (VPA)-induced hyperammonemia (VIH), is an increase in blood ammonia levels without any alteration of hepatic enzymes, which can occur during VPA treatment. We aimed to determine the prevalence rate and the risk factors for VIH and its association with cognitive functions. A prospective, cross-sectional study was conducted. Patients aged between 18 and 64 who were on VPA treatment and who diagnosed with mood disorders or epilepsy were enrolled in this study (n = 107). For cognitive assessment, Serial 7's and Subjective Memory Complaints Questionnaire (SMCQ) were used. Blood samples were collected for blood VPA and ammonia levels along with other laboratory tests. 55,3% of the sample were considered as VIH. Blood ammonia level significantly correlates with VPA blood levels, total daily dose of VPA and total number of medications concurrently used, but no significant correlation was found between blood ammonia level and cognitive test scores. Gender, body weight, blood VPA levels and the total number of medications concurrently used significantly predicted blood ammonia levels (F(4,81) = 2670, p = 0,038, R2 = 0,116). VIH is relatively high in our sample. There is a dose-dependent association between VPA and blood ammonia level. No association was found between cognitive functions and hyperammonemia however with some limitations. Future, prospective cohort studies are needed.
