Clinical trials

There are still no reliable biomarkers for migraine; the diagnosis is based on symptomatology, and the pathogenesis remains largely a mystery. However, the past decade has seen a shift from a trial-and-error treatment strategy to a more biologically driven approach using CGRP-targeted drugs (gepants) and monoclonal antibodies (mAbs). This study aims to profile levels of perivascular and hypothalamic neuropeptides, as well as microRNA (miRNA) and neurotrophins, in individuals with migraine. The study builds on a previous pilot investigation (Neuropeptides during migraine attacks, REK 808581).

The main aim of this clinical trial is to learn about the effect of carbohydrate-rich diet as a treatment for AIP (acute intermittent porphyria). Aim: Investigate the diet's impact on tissue and serum glucose, plasma insulin, cytokine levels, amino acids, and gut microbiota in AIP, and their correlation with PBG (Porphobilinogen). Aim: Assess the diet's effect on AIP symptoms and health status in AIP. Aim: Measure the effect of a high-carbohydrate diet on mitochondrial activity in AIP Aim: Map and detect potential mutations in mitochondrial genomic DNA in AIP Aim: Discover new markers in AIP through RNA sequencing and machine learning. Participants will follow two diet plans, a 4-week intervention with 60-65 E% carbohydrates and a 4 week intervention with 40-45 E% carbohydrates.

The goal of this clinical trial is to investigate patient harm/ adverse events, overall survival and health related quality of life under treatment with immunotherapy medication in cancer patients when they are followed up by a personalized digital program where the patients report symptoms directly to health care personnel. The main questions the clinical trial aims to answer are: * How often and how severe are immunotherapy related adverse events/ side effects when patients are followed up by a digital personalized patient-reporting system compared to standard follow-up? * How are life quality and survival affected for patients followed up by a digital personalized patient-reporting system compared to follow-up standard follow-up?? Participants under immunotherapy cancer treatment will be followed up by a digital patient reporting program in one group, and compared to a group of cancer patients receiving the same treatment, but with standard follow-up without a digital program in another group. Researchers will compare the two groups to see if there any differences in how many patients who develop immunotherapy related patient harm and how long the patients live.
