Clinical trials

Lupus nephritis (LN) is a severe manifestation of systemic lupus erythematosus (SLE) that can lead to irreversible kidney damage if not detected and managed promptly. LN is classified and treated based on its histopathological features obtained by invasive kidney biopsy. Recent research has suggested urinary extracellular vesicles (uEVs) as potential non-invasive biomarkers. The primary objective of this prospective study is to investigate the utility of uEVs in LN.

Nephrotic syndrome (NS) is characterized by gross proteinuria (\>3.5 g/day), hypoalbuminaemia, edema and often hyperlipidemia. Hyperlipidemia is correlated with increased morbidity and mortality. The study aim is to investigate the role of the protein convertase subtilisin/kexin type 9 (PCSK9) in hyperlipidemia of NS, which has been suggested to play an important role. This is done by testing the following hypotheses: 1. PCSK9 is increased in patients with NS and hyperlipidemia compared to kidney-healthy controls 2. The level of PCSK9 in plasma correlates to the degree of proteinuria. 3. PCSK9 i increased in the kidney tissue of patients with NS The study will compare plasma levels of PCSK9 in correlation with degree of protein in the urine between test persons with NS and kidney healthy controls. Furthermore the investigators will study the the degree of PCSK9 in the kidney in biopsies obtained from test persons with nephrotic syndrome and test persons without proteinuria.

The purpose of the study is to examine whether incision type has an influence on the development of groin wound complications after operation in the groin in vascular surgery. The main questions it aims to answer are: Does a transverse incision in the groin lead to fewer surgical site complications than a longitudinal incision? Does a transverse incision lead to fewer readmissions, fewer reoperations, shorter length of hospital stay, and a lower amputation rate. Participants will undergo vascular surgery in the groin with either a transverse or longitudinal incision. The incision type will be selected randomly.

This pragmatic multicenter randomized controlled trial (RCT) includes adult participants with an acute humeral shaft fracture to compare surgical fixation of humeral shaft fracture to non-surgical treatment with early identification and treatment of delayed union by a patient-reported outcome after 52 weeks. The trial population of 287 participants The trial population is divided in two age-groups due to the changes in DASH score by age. The definition of delayed union differs in the young and elderly population to consider dissimilarity in bone healing rates and the timepoint for crossover is therefor different between the groups. Participants will be randomized 1:1 between non-surgical treatment and surgical treatment. The primary outcome is the Disability of Arm, Shoulder and Hand (DASH) score at 52 weeks, and is assessor blinded. The secondary outcomes are DASH score earlier than 52 weeks, EQ-5D-5L, pain assessed by visual analogue score, Constant-Murley score including elbow range of motion and anchor-questions collected at all timepoints throughout the trial. All complications will be reported including; infection, nerve or vascular injury, surgical revisions (implant malpositioning, hardware failure, aseptic loosening and peri-implant fracture), major adverse cardiovascular events, other major adverse events and mortality. SHAFT will provide information on the effectiveness of two standard treatments for humeral shaft fractures, while taking the dilemmas within the population into account.
