Association of Polycystic Ovaries with the Use of Valproic Acid in Jordanian Epileptic Patients

Clinical Drug Investigation volume 23, pages 527–532 (2003)Cite this article

Abstract

Objective: To investigate the frequency of occurrence of polycystic ovaries (PCO) in women taking valproic acid (VPA) as monotherapy for epilepsy.

Study design and patients: 163 epileptic patients were seen at the outpatient neurology clinic at Princess’s Basma Teaching Hospital, Irbid, and Basheer Hospital, Amman, Jordan. A detailed medical history was taken from the patients followed by a clinical examination and vaginal ultrasonography of the ovaries.

Results: 102 patients (62.5%) had primary generalised seizures, 46 patients (28.2%) had partial seizures and 15 patients (9.2%) had partial secondary generalised seizures. Mean age ± standard error of the mean (SEM) was 29.8 ± 0.97 years. The duration of epilepsy and treatment with VPA were (mean ± SD) 9.1 ± 0.48 and 7.9 ± 0.4 years, respectively. The dose and serum concentrations of VPA were (mean ± SD) 983.9 ± 101.96mg and 52.7 ± 4.7 mg/L, respectively. Mean body mass index (BMI) was 25.6 ± 0.92 kg/m2. The mean weight gain was 6.6 ± 1.3kg (range 2–24kg). Menstrual abnormalities were detected in 58 (35.6%) patients. Twelve patients (7.4%) had PCO; these patients were compared with 17 patients without PCO selected randomly. There was a statistically significant difference in testosterone level and BMI values in patients with PCO compared with those without negative PCO. Patients with PCO had a mean ± SEM serum testosterone level of 1.2 ± 0.18 µg/L and BMI values of 29.24 ± 1.75 kg/m2. However, patients without PCO had a serum testosterone level of 0.61 ±0.1 µg/L and a BMI of 21.91 ± 0.7 kg/m2. Menstrual abnormalities were detected in all patients with PCO and in eight patients without PCO. Hirsutism was found in four cases with PCO and in one case with no PCO. There were no statistically significant differences in the duration of therapy, doses and serum concentrations of VPA in patients with PCO compared with those without PCO.

Conclusion: These results suggest an association between the use of VPA and PCO, hyperandrogenism, obesity and menstrual abnormalities. For women receiving VPA therapy, clinicians should consider performing an assessment of ovarian structure and function, especially if these patients develop menstrual cycle disturbances during treatment.
