  • Rituximab in adult minimal change disease and focal segmental glomerulosclerosis - What is known and what is still unknown?
  • 2020
  • Ingår i: Autoimmunity Reviews. - : Elsevier. - 1568-9972 .- 1873-0183. ; 19:11
  • Forskningsöversikt (refereegranskat)abstract
    • Primary forms of minimal change disease and focal segmental glomerulosclerosis are rare podocytopathies and clinically characterized by nephrotic syndrome. Glucocorticoids are the cornerstone of the initial immunosuppressive treatment in these two entities. Especially among adults with minimal change disease or focal segmental glomerulosclerosis, relapses, steroid dependence or resistance are common and necessitate re-initiation of steroids and other immunosuppressants. Effective steroid-sparing therapies and introduction of less toxic immunosuppressive agents are urgently needed to reduce undesirable side effects, in particular for patients whose disease course is complex. Rituximab, a B cell depleting monoclonal antibody, is increasingly used off-label in these circumstances, despite a low level of evidence for adult patients. Hence, critical questions concerning drug-safety, long-term efficacy and the optimal regimen for rituximab-treatment remain unanswered. Evidence in the form of large, multicenter studies and randomized controlled trials are urgently needed to overcome these limitations.

  • Rituximab in Membranous Nephropathy
  • 2021
  • Ingår i: Kidney International Reports. - : Elsevier Inc.. - 2468-0249. ; 6:4, s. 881-893
  • Forskningsöversikt (refereegranskat)abstract
    • Membranous nephropathy (MN) is the most common cause of primary nephrotic syndrome among adults. The identification of phospholipase A2 receptor (PLA2R) as target antigen in most patients changed the management of MN dramatically, and provided a rationale for B-cell depleting agents such as rituximab. The efficacy of rituximab in inducing remission has been investigated in several studies, including 3 randomized controlled trials, in which complete and partial remission of proteinuria was achieved in approximately two-thirds of treated patients. Due to its favorable safety profile, rituximab is now considered a first-line treatment option for MN, especially in patients at moderate and high risk of deterioration in kidney function. However, questions remain about how to best use rituximab, including the optimal dosing regimen, a potential need for maintenance therapy, and assessment of long-term safety and efficacy outcomes. In this review, we provide an overview of the current literature and discuss both strengths and limitations of “the new standard.”

  • An Open Resource for Non-human Primate Imaging
  • 2018
  • Ingår i: Neuron. - 0896-6273 .- 1097-4199. ; 100:1, s. 61-74
  • Tidskriftsartikel (refereegranskat)abstract
    • Non-human primate neuroimaging is a rapidly growing area of research that promises to transform and scale translational and cross-species comparative neuroscience. Unfortunately, the technological and methodological advances of the past two decades have outpaced the accrual of data, which is particularly challenging given the relatively few centers that have the necessary facilities and capabilities. The PRIMatE Data Exchange (PRIME-DE) addresses this challenge by aggregating independently acquired non-human primate magnetic resonance imaging (MRI) datasets and openly sharing them via the International Neuroimaging Data-sharing Initiative (INDI). Here, we present the rationale, design, and procedures for the PRIME-DE consortium, as well as the initial release, consisting of 25 independent data collections aggregated across 22 sites (total = 217 non-human primates). We also outline the unique pitfalls and challenges that should be considered in the analysis of non-human primate MRI datasets, including providing automated quality assessment of the contributed datasets.

  • 90Y-edotreotide for metastatic carcinoid refractory to octreotide
  • 2010
  • Ingår i: Journal of Clinical Oncology. - 0732-183X .- 1527-7755. ; 28:10, s. 1652-1659
  • Tidskriftsartikel (refereegranskat)abstract
    • PURPOSE: Metastatic carcinoid is an incurable malignancy whose symptoms, such as diarrhea and flushing, can be debilitating and occasionally life-threatening. Although symptom relief is available with octreotide, the disease eventually becomes refractory to octreotide, leaving no proven treatment options. The goal of this study was to evaluate the clinical effect of using (90)Y-edotreotide to treat symptomatic patients with carcinoid tumors. PATIENTS AND METHODS: Patients enrolled had metastatic carcinoid, at least one sign/symptom refractory to octreotide, and at least one measurable lesion. Study treatment consisted of three cycles of 4.4 GBq (120 mCi) (90)Y-edotreotide each, once every 6 weeks. RESULTS: Ninety patients were enrolled in the study. Using Southwest Oncology Group tumor response criteria, 67 (74.%) of 90 patients (95% CI, 65.4% to 83.4%) were objectively stable or responded. A statistically significant linear trend toward improvement was demonstrated across all 12 symptoms assessed. Median progression-free survival was significantly greater (P = .03) for the 38 patients who had durable diarrhea improvement than the 18 patients who did not (18.2 v 7.9 months, respectively). Adverse events (AEs) were reported in 96.7% (87 of 90) of patients. These AEs consisted primarily of reversible GI events (76 of 90), which could be caused in part by concomitant administration of amino acid solution given to reduce radiation exposure to the kidneys. There was one case each of grade 3 oliguria and grade 4 renal failure, each lasting 6 days. CONCLUSION: (90)Y-edotreotide treatment improved symptoms associated with malignant carcinoid among subjects with no treatment alternatives. Treatment was well-tolerated and had an acceptable expected AE profile.

  • The WALLTURB joined experiment to assess the large scale structures in a high reynolds number turbulent boundary layer
  • 2011
  • Ingår i: ERCOFTAC Series. - 1382-4309 .- 2215-1826. ; 14, s. 64-73
  • Konferensbidrag (refereegranskat)abstract
    • Experiments, involving the joint effort of three European teams and aiming at using the state-of-the-art techniques to study the dynamics of the high Reynolds turbulent boundary layer, have been performed in June 2006 in the LML large wind tunnel. A set of four stereoscopic PIV systems and a rake of 143 hot wires were used to provide synchronised measurements. This paper summarises these ex-periments, presents sample results of both PIV and hot-wire rake data and illustrates the complementarity of such a coupled approach that combines the advantages of each technique.

  • 'Are The Times A-Changin'? Trends in adolescent substance use in Europe
  • 2018
  • Ingår i: Addiction. - 0965-2140 .- 1360-0443. ; 113:7, s. 1317-1332
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims To estimate temporal trends in adolescents' current cigarette, alcohol and cannabis use in Europe by gender and region, test for regional differences and evaluate regional convergence. Design and Setting Five waves of the European School Survey Project on Alcohol and Other Drugs (ESPAD) from 28 countries between 1999 and 2015. Countries were grouped into five regions [northern (NE), southern (SE), western (WE), eastern Europe (EE) and the Balkans (BK)]. Participants A total of 223 814 male and 211 712 female 15-16-year-old students. Measurements Daily cigarette use, weekly alcohol use, monthly heavy episodic drinking (HED) and monthly cannabis use. Linear and quadratic trends were tested using multi-level mixed-effects logistic regression; regional differences were tested using pairwise Wald tests; mean absolute differences (MD) of predicted prevalence were used for evaluating conversion. Findings Daily cigarette use among boys in EE showed a declining curvilinear trend, whereas in all other regions a declining linear trend was found. With the exception of BK, trends of weekly drinking decreased curvilinear in both genders in all regions. Among girls, trends in WE, EE and BK differed from trends in NE and SE. Monthly HED showed increasing curvilinear trends in all regions except in NE (both genders), WE and EE (boys each). In both genders, the trend in EE differed from the trend in SE. Trends of cannabis use increased in both genders in SE and BK; differences were found between the curvilinear trends in EE and BK. MD by substance and gender were generally somewhat stable over time. Conclusions Despite regional differences in prevalence of substance use among European adolescents from 1999 to 2015, trends showed remarkable similarities, with strong decreasing trends in cigarette use and moderate decreasing trends in alcohol use. Trends of cannabis use only increased in southern Europe and the Balkans. Trends across all substance use indicators suggest no regional convergence.
