Pharmacokinetic Variability of Sulthiame: The Impact of Age, Drug-Drug Interactions, and Biochemical Markers of Toxicity in Patients with Epilepsy.

Purpose: Sulthiame is an antiseizure medication increasingly used for epilepsy. The aim of this study was to investigate the pharmacokinetic variability of sulthiame in children and adults with epilepsy with respect to age, comedication, dose, serum concentration, and biochemical markers of toxicity in a clinical setting.

Method: Retrospective quantitative data from the therapeutic drug monitoring (TDM) database at the Section for Clinical Pharmacology, the National Center for Epilepsy, Norway (2015-2021), were used.

Higher TNFα responses in young males compared to females are associated with attenuation of monocyte adenylyl cyclase expression.

Tumor necrosis factor α (TNFα) expression is strongly attenuated by the intracellular signaling mediator cyclic adenosine monophosphate (cAMP), which is synthesized by adenylyl cyclase (AC) enzymes. We have compared AC regulation and TNFα production in male and female monocytes, and characterized the role of monocyte AC isoforms in TNFα regulation. Males and females, age groups 20-30 years and 50-70 years donated blood for this study.

Regulation of CCN1 (Cyr61) in a porcine model of intestinal ischemia/reperfusion.

Intestinal ischemia is a serious condition that may lead to both local and systemic inflammatory responses. Restoration of blood supply (reperfusion) to ischemic tissues often increases the extent of the tissue injury. Cysteine-rich angiogenic inducer 61 (Cyr61)/CCN1 is an extracellular matrix-associated signaling protein that has diverse functions.

Human monocyte responses to lipopolysaccharide and 9-cis retinoic acid after laparoscopic surgery for colon cancer.

Surgery, even modern minimal invasive laparoscopic surgery, induces an initial inflammatory and acute phase response which is followed by a period of immunosuppression rendering surgical patients more susceptible to infection. Here, we aimed to study changes in monocyte inflammatory responses and inflammatory modulation mechanisms following laparoscopic colorectal surgery for colon cancer. Blood samples were collected from 19 colon cancer patients before, directly after and daily for 3 days following surgery.
