- BACKGROUND:Severe congenital neutropenia (SCN) is an immunodeficiency characterized by disturbed myelopoiesis and an absolute neutrophil count (ANC) <0.5 × 10(9)/L. SCN is also a premalignant condition; a significant proportion of patients develop myelodysplastic syndrome or leukemia (MDS/L). Allogeneic hematopoietic stem cell transplantation (HSCT) is the only curative treatment for SCN.PROCEDURE:Since 2004, eight HSCT have been performed in seven patients at our center. The indications were transformation to MDS/L (n = 2), granulocyte colony-stimulating factor receptor (CSF3R) mutation(s) (n = 2), granulocyte colony-stimulating factor (G-CSF) resistance (n = 2), and at the patient's own request (n = 1).RESULTS:The mean age at transplantation was 13 years (2.8-28 years) (mean follow-up 32 months, range 21-60). Three patients harbored ELANE mutations, three HAX1 mutations, and in one patient no causative mutation was identified. Two of the ELANE mutations were novel mutations. Three patients initially received myeloablative conditioning and four had reduced intensity conditioning (RIC). Three grafts were from HLA-identical siblings, three from matched unrelated donors and two were cord blood units. Engraftment occurred in all patients. Two of seven (29%) patients died; both had MDS/L and both were among the three that underwent myeloablative conditioning. One patient has chronic GVHD 2 years post-transplant.CONCLUSIONS:The role of HSCT should be explored further in patients with SCN. In particular, the influence of the conditioning regime needs to be evaluated in a larger cohort of patients.

- Angiotensin-converting enzyme inhibitors (ACEi) have immunomodulating properties and have been suggested to protect against endothelial injury, for example myocardial infarction and reperfusion injury. We tested whether two ACEi (captopril and enalapril), differing in a thiol group, protected human umbilical vein endothelial cells (HUVEC) from cytotoxicity induced by polymorphonuclear neutrophils (PMN) in vitro, when cells were activated by tumour necrosis factor-α (TNFα) or the arachidonate derivative lipoxin-A4 (LXA4), using separate cytotoxicity pathways. When 51Cr labelled HUVEC were treated with captopril (0–500 μm) or enalapril (0–100 μm) for 2 h and then activated by TNFα (100 ng/ml) for 24 h, a significant, dose-dependent reduction of 51Cr release was observed. Similarly, captopril reduced 51Cr release when LXA4 (0.1 μm) was used to stimulate PMN for 4 h. Among previously defined mechanisms of significance for the cytotoxic reaction, expression of ICAM-1, but not intracellular Ca2+ changes in PMN or PMN adherence to HUVEC, were reduced by ACEi treatment. Moreover, both ACEi inhibited HUVEC surface expression of TNFα receptor I (but not II). Thus, these ACEi, particularly captopril, interfere with PMN-induced cytotoxicity for endothelial cells by modulating pro-inflammatory surface receptors, which is a novel effect that might be explored for further therapeutic approaches.

Forskningsöversikt (refereegranskat)abstract
- In an ongoing health-technology assessment of haemophilia treatment in Sweden, performed by the governmental agency Dental and Pharmaceutical Benefits Agency (TLV; tandvårds-och läkemedelsförmånsverket), the Swedish Council on Health Technology Assessment (SBU; statens beredning för medicinsk utvärdering) was called upon to evaluate treatment of haemophilia A and B and von Willebrand's disease (VWD) with clotting factor concentrates. To evaluate the following questions: What are the short-term and long-term effects of different treatment strategies? What methods are available to treat haemophilia patients that have developed inhibitors against factor concentrates? Based on the questions addressed by the project, a systematic database search was conducted in PubMed, NHSEED, Cochrane Library, EMBASE and other relevant databases. The literature search covered all studies in the field published from 1985 up to the spring of 2010. In most instances, the scientific evidence is insufficient for the questions raised in the review. Concentrates of coagulation factors have good haemostatic effects on acute bleeding and surgical intervention in haemophilia A and B and VWD, but conclusions cannot be drawn about possible differences in the effects of different dosing strategies for acute bleeding and surgery. Prophylaxis initiated at a young age can prevent future joint damage in persons with haemophilia. The available treatment options for inhibitors have been insufficiently assessed. The economic consequences of various treatment regimens have been insufficiently analysed. Introduction of national and international registries is important.
