RESUMO
INTRODUCTION: Glioma is the most common intracranial primary brain tumor. Patients with glioma often suffer from epilepsy, anxiety and depression. Aims of this study were to identify risk factors for drug-treated anxiety and depression, and to determine the use of psychiatric medication in a national glioma cohort. METHODS: Data from the Cancer Registry of Norway on all persons diagnosed with glioma WHO grade II-IV 2004-2010 were linked with data from the Norwegian Prescription Database. Cox regression analysis was used to assess risk factors for drug-treated anxiety and depression. Standardized incidence ratios were calculated for psychiatric medication dispensed to glioma patients and compared to the general population. RESULTS: The glioma cohort consisted of 1056 males and 772 females. Of the 1828 patients, 565 had glioma grade II-III, and 1263 had grade IV. The patients with glioma grade II-III who were treated with levetiracetam had an increased risk for drug-treated anxiety compared to patients without levetiracetam; hazard ratio 2.8 (95% confidence interval 1.7-4.9). Female gender increased the risk for drug-treated anxiety compared to males in patients with glioma grade IV; hazard ratio 1.5 (95% confidence interval 1.2-2.0). Antidepressants were less frequently dispensed to patients with glioma grade II-III and epilepsy than to the general population. CONCLUSIONS: Patients with glioma grade II-III on levetiracetam had an increased risk for drug-treated anxiety. The subgroup of patients with glioma grade II-III and epilepsy received less antidepressants than the general population.

PURPOSE: To report the clinical outcome of nicotine exposure in patients with autosomal dominant sleep-related hypermotor epilepsy (ADSHE), along with serum concentrations of the major nicotine metabolite cotinine. METHODS: We recruited 17 ADSHE patients with CHRNA4 mutations (12 with p.S280F and 5 with p.L291 dup). Clinical characteristics were collected from hospital records. A telephone interview was performed on the use and seizure-reducing effect of nicotine applying a six-point rating scale from "none" to very good". Serum concentrations of cotinine were measured in 14 nicotine users. RESULTS: All patients but one had ever used nicotine. Nine had used snuff; seven were current users. Eleven had used transdermal nicotine; nine were current users. Seven reported long-lasting seizure control, all used nicotine, four transdermal nicotine and three snuff. In 78% of patients using continuous transdermal nicotine, the effect was rated as good or very good. Cotinine concentrations were 453 ± 196 (mean ± SD) nmol/l in seven patients using transdermal nicotine only vs. 1241 ± 494 nmol/l in seven using other forms of nicotine. No correlation with seizure control was found. Three patients experienced improvement with transdermal delivery compared to snuff. CONCLUSION: This is the hitherto largest observational study supporting a favorable effect of nicotine in this specific seizure disorder. Better seizure control from transdermal nicotine compared to only day-time consumption suggests benefit from exposure throughout the night. According to current clinical experience, patients with uncontrolled ADSHE harboring relevant mutations should be offered precision treatment with transdermal nicotine.
