The main concerns associated with epilepsy during pregnancy consist of maternal and fetal risks from uncontrolled seizures, and harmful effects of the treatment on the development of the offspring. Although seizure control is maintained in the majority, worsening occurs in a fraction of childbearing women with epilepsy. As multiple factors associated with(More)
PURPOSE To study the interaction between lamotrigine (LTG) and hormonal contraception. METHODS LTG serum concentrations of female patients using either no hormonal contraception (n=18), an ethinyl estradiol (EE)-containing (n=11), or a progestogen (PG)-only-containing compound (n=16) were analyzed. Patients were recruited prospectively, and blood samples(More)
We present a systematic study on the interaction potential of lamotrigine, with focus on psychoactive drugs. A review of routine serum concentration measurements of lamotrigine performed in our laboratory yielded a total of 1733 serum samples from 829 patients (530 women, 299 men) suitable for statistical analysis. Main results for the whole study(More)
The placenta contains a large variety of metabolizing enzymes, among them UDP-glucuronosyltransferase (UGT). Several UGT2B isozymes have so far been detected in human placenta, but little is known on placental expression of UGT1A isozymes. The antiepileptic drug lamotrigine (LTG) is a UGT1A4-substrate, and its serum concentration falls by over 50% during(More)
Derailed T-cell activation can give rise to life-threatening macrophage activation, the final common pathway of the different forms of reactive macrophage activation syndromes (rMAS). Besides inappropriate activation of the immune system, impaired termination of immune responses might be another mechanism leading to rMAS. The Fas (CD95)/Fas ligand (CD95(More)
When treating pregnant women with antiepileptic drugs (AEDs), clinicians have to balance potential fetal adverse effects against the risks of uncontrolled maternal disease. Only recently have emerging scientic data provided a rational basis for treatment decisions considering both aspects. The focus of research is currently moving from the first to the(More)
OBJECTIVES To measure the serum concentrations of lamotrigine throughout a complete menstrual cycle. METHODS Serum concentrations of lamotrigine, estradiol, and progestogen throughout a menstrual cycle were measured in 2 young women not using hormonal contraception. RESULTS AND CONCLUSIONS The physiological hormonal fluctuations during an ovulatory(More)
QUESTIONS UNDER STUDY starting treatment of reactive macrophage activation syndromes as early as possible (rMAS, haemophagocytic lymphohistiocytosis), e.g., with intravenous immunoglobulins (IVIG), seems to be essential for optimal outcome. However, there is no diagnostic gold standard which reliably indicates need for early treatment. We used a simple(More)
The underlying mechanisms of reactive macrophage activation syndromes (rMAS) are not understood in detail, and there is no specific treatment. This observational study was prompted by intravenous immunoglobulin (IVIG), dramatically halting two distinct rMAS episodes in the same patient. We evaluated the potential benefits of IVIG administration in treating(More)
This study investigated data obtained from whole blood fatty acid (FA) composition of 3476 Norwegian and Swedish individuals, which provided background information including age, gender, nationality and self-motivated n-3 supplement consumption. The aim of this paper was to statistically relate this background information on the subjects to their whole(More)
