Konferensbidrag (refereegranskat)abstract
- Professor Inga Marie Nilsson (1923-99) was a pioneer in the field of bleeding and thrombo-embolic disorders and made several major scientific contributions during her career. To honour her memory, colleagues from all over the world were invited to cover several aspects of haemostasis by giving state-of-the-art lectures at an international symposium in Malmö on September 22-23, 2000, chaired by Professors Lou Aledort and Erik Berntorp. Colleagues of Professor Nilsson in Malmö gave a short introduction to each topic. A short review of the meeting will be presented.

Consensus perspectives on prophylactic therapy for haemophilia: summary statement.
- 2003

- Participants in an international conference on prophylactic therapy for severe haemophilia developed a consensus summary of the findings and conclusions of the conference. In the consensus, participants agreed upon revised definitions for primary and secondary prophylaxis and also made recommendations concerning the need for an international system of pharmacovigilance. Considerations on starting prophylaxis, monitoring outcomes, and individualizing treatment regimens were discussed. Several research questions were identified as needing further investigation, including when to start and when to stop prophylaxis, optimal dosing and dose interval, and methods for assessment of long-term treatment effects. Such studies should include carefully defined cohorts, validated orthopaedic and quality-of-life assessment instruments, and cost-benefit analyses.

Factor VIII inhibitors in two families with mild haemophilia A: structural analysis of the mutations
- 2000

Ingår i: Haemostasis. - : S. Karger AG. - 0301-0147. ; 30:5, s. 268-279

Tidskriftsartikel (refereegranskat)abstract
- The development of inhibitory antibodies against coagulation factor VIII (FVIII) in patients with mild haemophilia A is uncommon. We describe here two families in which three or two members have developed inhibitors, suggesting a familial predisposition. The mutations found, in the A2 (Arg593Cys) and C1 domains (Tyr2105Cys), have been reported to give rise to inhibitor development in single individuals in addition to the family cluster we describe, strongly suggesting that these amino acid substitutions give rise to a more immunogenic protein. The analysis of structural models of activated factor VIII revealed that Arg593 is solvent-exposed and involved in a network of electrostatic interactions while Tyr2105 is partially buried and has hydrophobic interactions essentially with Ile2144. All these residues are strictly conserved in the FVIII amino acid sequence from man, pig and mouse, suggesting, at least, that they have structural roles. We propose that the two mutations in these families could cause mild haemophilia A because they induce local conformational changes (and possible secretion or intermolecular interaction problems, e.g., with von Willebrand factor) compatible with immunogenicity and production of inhibitors against the infused wild-type FVIII.

Treatment of children with haemophilia in Europe: A survey of 20 centres in 16 countries
- 2000

Ingår i: Haemophilia. - : Wiley. - 1351-8216. ; 6, s. 619-624

Tidskriftsartikel (refereegranskat)abstract
- A survey was made of the current status of treatment of haemophilic boys at 20 centres in 16 European countries and includes approximately 1500 of the estimated 6500 haemophiliacs in the participating countries. Many mild haemophiliacs are not seen, or seen infrequently, at haemophilia centres and this requires study. Nine of 18 centres provide continuous prophylaxis to 80-100% of their patients, five centres provide it to 55-80% and the remaining four centres to 15-40% of the boys. The median dose given was 6240 U kg-1 year-1 (range 3120-7800). Four centres administered only recombinant concentrates to children with severe haemophilia A, while seven centres administered recombinant concentrates to 75-90% and the remaining centres to less than 50% of the boys (two centres <10%). When asked for the choice of concentrate for a newly diagnosed boy with severe haemophilia A, all but one centre preferred recombinant concentrate. Most boys below 6 years received concentrates via a peripheral vein but three centres preferred a central venous line for 80-100% of the boys. Thirteen of 18 centres applied home treatment to 84-100% of the boys and the remaining five centres to 57-77% of the boys.

Comparative genome- and proteome analysis of cerebral cortex from MK-801-treated rats.

- cDNA microarrays and two-dimensional gel-electrophoresis in combination with mass spectrometry, were used to screen alterations in mRNA and protein levels, respectively, in cerebral cortex of MK-801-treated rats. The rats were divided in two groups; group 1 (short-term treated) and group 2 (long-term treated). In group 1, four genes were up-regulated and five down-regulated. In group 2, seven genes were up-regulated and six down-regulated. In group 1, the levels of one protein was increased and eight proteins reduced. In group 2, the levels of two proteins were increased and four proteins reduced. Several of the altered genes (casein kinase 2, glutamic acid decarboxylase, synaptotagmin, gamma aminobutyric acid [GABA] transporter, creatine kinase, and cytochrome c oxidase) and proteins (superoxide dismutase, hsp 60, hsp 72 and gamma-enolase) have previously been connected to schizophrenia. Alterations of the genes (microglobulin, c-jun proto-oncogene, 40S ribosomal protein S19, adenosine diphosphate (ADP)-ribosylation factors, platelet-derived growth factor, fructose-bisphophate aldolase A, and myelin proteolipid) and the proteins (stathmin, H+-transp. Adenosine triphosphate (ATP) synthase, pyruvate dehydrogenase, beta-actin and alpha-enolase), have not, to our knowledge, earlier been implicated in schizophrenia pathology. Overall, these results with a combined approach of genomics and proteomics add to the validity of subchronic N-methyl-D-aspartate (NMDA)-receptor antagonist treatment as an animal model of schizophrenia.

- Two-dimensional gel-electrophoresis in combination with mass spectrometry is a powerful approach to compare protein expression in brain tissues. Using this proteomic approach, and based on the hypothesis that schizophrenia involves hypoglutamergic brain function, alterations in protein levels in the thalamus of rats treated with the N-methyl-D-aspartate (NMDA) receptor antagonist [+]-5-methyl-10,11-dihydro-5H-dibenzo-[a,d]-cycloheptene-5,10-iminehydrogenmaleate (MK-801), as compared to saline-treated animals, were assessed in an unbiased fashion. The rats were divided into two groups; group 1 (short-term treated) and group 2 (long-term treated). In group 1, the levels of seven proteins were increased and four proteins reduced. In group 2, the levels of six proteins were reduced. Several of the altered proteins (heat shock proteins 60 and 72, albumin, dihydropyrimidinase related protein-2, aldolase c, and malate dehydrogenase) have previously been connected to schizophrenia. Alterations of other proteins (dihydrolipoamide acetyltransferase component of pyruvate dehydrogenase complex E2, guanine deaminase, alpha-enolase, aconitase, ATP-synthase and alpha-internexin), have not, to the best of our knowledge, earlier been implicated in schizophrenia pathology. Our results show the high potential of using proteomic methods for the validation of animal models of schizophrenia and to identify new proteins involved in the pathophysiological mechanisms of schizophrenia.
