Damoctocog alfa pegol (BAY 94-9027, Jivi ® ), is a site-specifically PEGylated, extended half-life recombinant factor VIII (FVIII) that is approved in several European and non-European countries for on-demand treatment and prophylaxis of bleeding in previously treated patients aged ≥ 12 years with hemophilia A. Reliable measurements can be obtained using most one-stage and chromogenic FVIII assays over a wide concentration range. The efficacy, safety and pharmacokinetics (PK) of damoctocog alfa pegol have been studied extensively in the PROTECT VIII clinical trials, and its long-term safety and effectiveness profile is continuing to build through observational and interventional real-world studies. The PK of damoctocog alfa pegol was shown to be improved as compared with that of sucrose-formulated rFVIII (rFVIII-FS, Kogenate ® ), and was also demonstrated to be non-inferior to and, for some variables, more favorable than rFVIII-Fc fusion protein, efmoroctocog alfa (Elocta ® ; NCT03364998), rurioctocog alfa pegol (BAX 855, Adynovate ® /Adynovi ® ; NCT04015492), and antihemophilic factor (recombinant) plasma/albumin-free method (rAHF-PFM, Advate ® ; NCT02483208). Damoctocog alfa pegol was generally well tolerated and none of the patients in any of the clinical trials, including the PROTECT VIII clinical program, HEM-POWR, or ongoing single-center studies, developed FVIII inhibitors. Efficacy for perioperative hemostasis has been demonstrated. Low bleeding rates were achieved across the studies, with twice weekly, every 5-day and every 7-day prophylaxis offering patients ≥ 12 years and their clinicians the chance to tailor treatment to individual needs and lifestyles, while maintaining long-term protection from bleeds and their consequences., (© 2024.

Introduction: Damoctocog alfa pegol (BAY 94-9027, Jivi ® ) is an approved extended half-life factor VIII (FVIII) for treatment of previously treated patients with haemophilia A aged ≥12 years. We report the final results of an interventional, post-marketing study of damoctocog alfa pegol prophylaxis in patients with severe haemophilia A., Methods: In this open-label, interventional, post-marketing, phase 4 trial (NCT04085458), previously FVIII-treated patients with severe haemophilia A aged ≥18 years received damoctocog alfa pegol for ≥100 exposure days (EDs). Patients initially received 45 IU/kg every 5 days (recommended) or 40 IU/kg twice-weekly. At Visit 3, patients' doses could be increased, or treatment frequency adapted. The primary endpoint was FVIII inhibitor development (titre ≥.6 Bethesda units). Secondary endpoints included anti-polyethylene glycol (PEG) antibody development, treatment-emergent adverse events (AEs) and annualized bleeding rate (ABR)., Results: Overall, 36 patients were enrolled; 32 patients received treatment, of whom, 27 completed the study. No patients developed FVIII inhibitors; three tested transiently positive for low-titre anti-PEG antibodies without clinical relevance. Three patients reported study-drug-related AEs of mild or moderate intensity. Two patients discontinued the study due to AEs. No deaths occurred. Most patients (70%) were treated with E5D/E7D regimens. The median (Q1;Q3) total ABR (N = 30) was 3.0 (.0;9.0) pre-study and 1.8 (.7;5.9) during the study., Conclusion: Damoctocog alfa pegol individualized prophylaxis regimens were well-tolerated with no immunogenicity concerns. ABRs improved following the switch from pre-study prophylaxis to damoctocog alfa pegol prophylaxis. These results support the favourable safety and efficacy profile of damoctocog alfa pegol prophylaxis., (© 2024 The Authors. Haemophilia published by John Wiley & Sons Ltd.)

Introduction: The current study describes real-world clinical outcomes and factor usage among patients with haemophilia B switching from standard half-life factor IX (SHL FIX) treatment to recombinant factor IX Fc fusion protein (rFIXFc) prophylaxis in European treatment centres., Methods: This non-interventional, retrospective, multicentre chart review evaluated medical records from adult and paediatric patients with haemophilia B in Denmark, Germany and the UK. Patients had documented SHL FIX treatment, on-demand or prophylaxis, for ≥ 6 months before starting rFIXFc prophylaxis, and subsequent data for ≥ 6 months afterwards (up to 24 months). Primary endpoints included annualised bleeding rates (ABRs), prophylactic factor consumption and injection frequency., Results: Data from 30 patients (24/30 [80.0%] with severe disease) showed overall mean (standard deviation, SD) ABRs of 4.7 (6.3) on SHL FIX treatment and 1.7 (2.3) after switching to rFIXFc prophylaxis. The reduction in mean (SD) ABRs was greater when switching from SHL FIX on-demand treatment (n = 6), with a decrease from 10.5 (9.9) to 2.6 (4.5), than when switching from SHL FIX prophylaxis (n = 24), with a decrease from 3.3 (4.3) to 1.5 (1.4). Among prior SHL FIX prophylaxis patients, switching to rFIXFc prophylaxis increased the proportion of those with zero bleeds from 21.7% to 45.8% during the 6 months before and after switching, respectively. In the total population, five of six target joints (83.3%) present when patients started rFIXFc prophylaxis subsequently resolved. In patients switching from SHL FIX prophylaxis to rFIXFc prophylaxis, mean (SD) weekly injection frequency was reduced by 1.0 (0.7) and mean (SD) factor consumption was reduced by 27.7 (49.6) IU/kg/week., Conclusion: This study demonstrates the effectiveness of rFIXFc prophylaxis in real-world clinical practice. Improvements in both clinical effectiveness and factor usage associated with rFIXFc prophylaxis may potentially reduce patient burden and improve quality of life., (© 2023. The Author(s).)

Purpose: In the past decades, haemophilia treatment has greatly improved the health of persons with haemophilia (PWH). This study compares PWH to the general population on social conditions and health., Methods: In December 2021, all Danes with moderate or severe haemophilia A or B, or von Willebrands disease type 3 were invited to participate in an online self-report survey concerning sociodemographic factors, self-rated health, teeth status, chronic health conditions, symptoms and loneliness. This study compares responses from the 124 adult male PWH with responses from a male general population sample (N = 4849). Analyses used logistic regression, controlling for age and highest completed education., Results: Fewer PWH were in the oldest age group (65-84 years). Controlling for age, no significant differences were found regarding cohabitation status or education. Fewer PWH were employed (OR = .48, [.33-.71])-particularly in the 45-64 age group. PWH were less likely to report good health (OR = .49, [.31-.77]). The odds of joint disease was much higher (OR = 13.00, [8.37-20.28]). Also, hypertension (OR = 2.25, [1.13-5.65]) and previous stroke (OR = 2.51, [1.44-3.50]) were more frequent. PWH were more likely to report pain in the arms/hands/legs/hips (OR = 2.94, [1.92-4.52]), but less likely to report pain in the head/neck/shoulder (OR = .66, [.45-.96])., Conclusion: The disease burden of haemophilia has improved so PWH resembles the general population in areas such as marriage and education. However, even for young PWH, the disease still imposes a significant burden from hemophilia arthropathy and pain in extremities and joints. Middle-aged PWH also have poorer levels of employment than same-aged peers., (© 2023 The Authors. Haemophilia published by John Wiley & Sons Ltd.)

Purpose: This study aimed to compare changes in the bone turnover markers (BTMs)-C-terminal telopeptide of type I collagen (CTX-I) and procollagen I N-terminal peptide (PINP)-with changes in the bone microarchitecture, assessed by high-resolution peripheral quantitative computed tomography (HR-pQCT), during treatment of patients with thyroid dysfunction., Methods: In women with newly diagnosed hypo- or hyperthyroidism, HR-pQCT variables, obtained from the tibia and the radius, were compared with BTMs. Data were collected at diagnosis and after at least 12 months of euthyroidism., Results: 73 women completed the study (hypothyroidism, n = 27; hyperthyroidism, n = 46). Among hyperthyroid patients, correlations were found between changes in BTMs and HR-pQCT variables, primarily for cortical variables in the tibia, i.e. cortical thickness (CTX-I, p < 0.001; PINP, p < 0.001), and volumetric bone mass density (vBMD) (CTX-I, p < 0.001; PINP, p < 0.001). Moreover, correlations between BTMs and estimated bone strength were found. In the hypothyroid subgroup, no significant findings existed after adjustment. Following treatment, less decrease in tibial vBMD was seen among patients with increasing CTX-I compared to those with a decreasing CTX-I level (p = 0.009). Opposite findings applied to PINP, as patients with decreasing PINP showed an increase in tibial vBMD, in contrast to a decline in this parameter among patients with increasing PINP (p < 0.001)., Conclusion: Changes in CTX-I and PINP correlated with HR-pQCT variables during the treatment of women with thyroid dysfunction. To some extent, these BTMs reflected the restoration of bone microarchitecture. CTX-I seems to be the most sensitive BTM in treatment-naïve thyroid diseases, while PINP is more useful for monitoring during treatment., Trial Registration Number: NCT02005250.

Introduction: Platelet function tests are used to screen and diagnose patients with possible inherited platelet function defects (IPFD). Some acquired platelet dysfunction may be caused by certain drugs or comorbidities, which need to be excluded before testing., Aims: To identify current practice among centres performing platelet function tests in Northern Europe., Methods: A total of 14 clinical centres from Sweden (six), Finland (two), Denmark (two), Norway (one), Estonia (two) and Iceland (one) completed the survey questionnaire, the population capture area of about 29.5 million., Results: Six of the 14 (42.8%) centres providing platelet function assessment represent comprehensive treatment centres (EUHANET status). A Bleeding score (BS) or ISTH bleeding assessment tool (ISTH BAT score) is evaluated in 11/14 (78.6%) centres and family history in all. Five/14 centres (35.7%) use structured preanalytical patient instructions, and 10/14 (71.4%) recorded questionnaire on the preassessment of avoidance of any drugs or natural products affecting platelet functions. Preliminary investigations of screening tests of coagulation are performed in 10/14 (71.4%), while in 4/14 (28.6%), the diagnostic work-up of IPFD and von Willebrand disease (VWD) is performed simultaneously. The work-up of IPFD includes peripheral blood smear in 10/14 (71.4%), platelet aggregometry in all, flow cytometry in 10/14 (71.4%) and Platelet Function Analysis (PFA) in 3/11 (28.6%). Molecular genetic diagnosis is available in 7/14 (50%) centres., Conclusions: The considerable variability in the current practice illustrates the need for harmonization between the Northern European centres according to the international registers (i.e. EUHASS) and IPFD guidelines (ISTH, EHA)., (© 2022 The Authors.

Despite current therapies, there remains an unmet need for treatment for patients with hemophilia. The main parts of two phase 2 trials established clinical proof-of-concept for once-daily, subcutaneous concizumab prophylaxis in patients with hemophilia A/B with inhibitors (HAwI/HBwI; explorer4) and severe hemophilia A without inhibitors (HA; explorer5). Here, we present results from extension parts of these trials, included to evaluate longer term safety and efficacy. Both trials included main (≥24 weeks) and extension (52-102 weeks) parts, with patients receiving concizumab 0.15 mg/kg with potential dose escalation to concizumab 0.20 or 0.25 mg/kg if they experienced ≥3 treated spontaneous bleeding episodes within 12 weeks. Endpoints included annualized bleeding rate (ABR), adverse events (AEs), and occurrence of antidrug antibodies. Thromboembolic events were AEs of special interest. Thirty-six patients with HA, 15 with HAwI, and 10 with HBwI were exposed to concizumab. Estimated ABRs during the main + extension parts at last dose level were 4.8 (95% confidence interval [CI], 3.2-7.2) and 6.4 (95% CI, 4.1-9.9) in explorer4 and explorer5, respectively (spontaneous ABRs were 1.8 [95% CI, 1.2-2.6] and 2.1 [95% CI, 1.3-3.3]). Most AEs were mild, with no deaths, events leading to withdrawal, or thromboembolic events. Anti-drug antibodies developed in 25% of patients and were low titer and transient, with no observed clinical effect in most cases. Results of the main + extension parts of these trials were consistent with results of the main parts. Ongoing phase 3 trials will further evaluate concizumab as a once-daily, subcutaneous treatment across hemophilia subtypes. These trials were registered at www.clinicaltrials.gov as #NCT03196284 and #NCT03196297., (© 2022 by The American Society of Hematology.

Purpose: Advanced targeted therapy has resulted in increasing life expectancy and incidence of age-related cardiovascular diseases like atrial fibrillation in patients with haemophilia. Oral anticoagulation constitutes a significant dilemma in this patient category as the risks of stroke and bleeding are difficult to balance. We sought to demonstrate the feasibility of left atrial appendage occlusion (LAAO) in patients with haemophilia and atrial fibrillation., Methods: All patients with haemophilia treated with LAAO at Aarhus University Hospital, Denmark, were identified from a local prospective database comprising all consecutive LAAO procedures from 2010 up to November 2020. Based on review of the medical records, a retrospective descriptive analysis was performed., Results: Seven patients with haemophilia A and atrial fibrillation underwent LAAO after multidisciplinary conference. Peri-procedural coagulation management was guided by factor VIII activity and treated with repeated bolus administrations of recombinant factor VIII targeting an activity of 100%. The implantation was successful in all patients with only minor bleeding complications post-procedurally. Based on these experiences, a suggested regime has been formulated., Conclusions: LAAO is feasible in haemophilia patients with concurrent atrial fibrillation. However, special care including intravenous substitution with coagulation factors must be given in the periprocedural management., (© 2021.

Background: Regular factor XIII (FXIII) prophylaxis is standard treatment for congenital FXIII A-subunit deficiency (FXIII-A CD). Recombinant factor XIII-A 2 (rFXIII-A 2 ) was extensively evaluated in the mentor trials., Objective: To assess real-world safety and treatment effectiveness of rFXIII-A 2 prophylaxis from the mentor 6 trial., Patients/methods: mentor 6 was a noninterventional, postauthorization safety study investigating rFXIII-A 2 prophylaxis in FXIII-A CD. rFXIII-A 2 treatment was observed for 2 to 6 years per patient. The primary end point was documentation of adverse drug reactions (including anti-FXIII antibody development). Secondary end points were serious adverse events (SAEs), medical events of special interest (MESIs), and annualized bleeding rate (ABR)., Results: Among 30 patients (mean age, 25.5 years), there were 44 adverse events (AEs) (30 mild, 13 moderate, 1 severe). Eleven AEs were possibly/probably related to rFXIII-A 2 . Of four MESIs, two were unlikely related to rFXIII-A 2 (accidental overdose, deep vein thrombosis), and two were possibly/probably related (nonneutralizing anti-FXIII antibody, decreased therapeutic response). All 10 SAEs were unlikely related to rFXIII-A 2 . Over a follow-up of 75.4 patient-years, there were six treatment-requiring bleeds (all trauma-related with no spontaneous bleeds), giving a treatment-requiring ABR of 0.066; five bleeds were treated successfully with rFXIII-A 2 . Eight of nine minor surgeries performed during rFXIII-A 2 prophylaxis reported successful hemostatic outcomes (one missing evaluation)., Conclusions: These data confirm that rFXIII-A 2 prophylaxis is well tolerated as long-term care. There were no spontaneous bleeds, ABR was low, and rFXIII-A 2 successfully treated bleeds in patients receiving rFXIII-A 2 prophylaxis., (© 2022 The Authors.

Introduction: Information about temporal development of von Willebrand disease (VWD) incidence at a population level is scarce. To our knowledge, no study has described the incidence of VWD at a population level., Aim: To estimate overall and annual incidence rates of hospital diagnosed VWD in Denmark between 1995 and 2016 as well as the frequency of hospital treated bleeding episodes before and after VWD diagnosis., Methods: A registry-based cohort study that included all Danish patients with a first diagnosis of VWD in Denmark, identified in the Danish National Patient Registry through 1995-2016., Results: We identified 1,035 patients with a diagnosis of VWD. The overall incidence rate of VWD in 1995-2016 was 8.6 (95% CI: 8.1-9.2). The annual age-standardized incidence rate per 100 000 person-years varied between 4.1 (95% CI: 2.4-5.9) in 1998 and 16.7 (95% CI: 13.1-20.3) in 2005. A prominent peak in rates appeared from 2002 to 2008. One and five years before VWD diagnosis, 6% and 11.5% of the patients had at least one hospital treated bleeding episode. One and five years after diagnosis, the corresponding percentages were 7.9% and 13.4%., Conclusion: These results are the first population-based estimates of VWD incidence. The incidence may be underestimated because asymptomatic individuals may not be diagnosed. The observed peak in incidence from 2002-2008 may be explained by increased medical attention, leading to more patients being diagnosed, rather than an actual increase in VWD incidence. However, overall, we observed no systematic changes in VWD incidence over the study period., (© 2021 John Wiley & Sons Ltd.)

Background: Between 1975 and 1985 a total of 91 Danish patients with moderate and severe hemophilia (PWH) was infected with HIV constituting a major scandal in the Danish health care system. This study describes the burden of HIV infection among Danish PWH by evaluating changes from 1988 to 2012 in well-being, social function, experiencing stigma and openness about disease among Danish HIV + PWH., Methods: Three anonymous surveys were conducted in 1988, 2001 and 2012 targeting all Danish patients with moderate to severe hemophilia. Survey responses were received from 53, 21 and 18 HIV + PWH respectively. A matched comparison sample of HIV - PWH was identified for each survey-year, using propensity score matching. Differences for each survey-year and trends over time were analyzed using ordinal logistic regression., Results: In 1988, HIV + PWH had more psychosomatic symptoms than HIV - PWH, but in 2001 life satisfaction was higher among HIV + PWH than among HIV - PWH. Tests of differences in trend over time showed larger improvements in life satisfaction among HIV + PWH than HIV - PWH, while HIV - PWH showed an increase in educational level compared to HIV + PWH. Analysis restricted to HIV + PWH showed an increase in perceived stigmatization., Conclusions: Differences between Danish HIV + and HIV - PWH regarding well-being and psychosomatic symptoms seem to have evened out between 1988 and 2012. However, results suggest that HIV + PWH still experience stigmatization and lower levels of education.

Results from the main parts (24 weeks) of 2 concizumab phase 2 trials are presented: explorer4 in hemophilia A (HA) or B (HB) with inhibitors (HAwI/HBwI) and explorer5 in HA. The trials aimed to evaluate the efficacy of daily subcutaneous concizumab prophylaxis (evaluated as annualized bleeding rate [ABR] at last dose level), with secondary objectives being safety and immunogenicity (assessed as number of adverse events [AEs] and antidrug antibodies [ADAs]). Patients received 0.15 mg/kg concizumab, with potential dose escalation to 0.20 and 0.25 mg/kg (if ≥3 spontaneous bleeding episodes within 12 weeks of concizumab treatment). Relevant pharmacokinetic/pharmacodynamic (PK/PD) parameters were assessed. Thirty-six HA, 9 HAwI, and 8 HBwI patients were exposed to concizumab. Most inhibitor patients (15 of 17; 88.2%) did not escalate the dose; all patients chose to continue to the extension phase of the trials. Clinical proof of concept for prevention of bleeding episodes was demonstrated in both trials. Estimated ABRs in HAwI and HBwI were lower vs HA: 3.0 (95% confidence interval [CI], 1.7; 5.3) and 5.9 (95% CI, 4.2; 8.5) vs 7.0 (95% CI, 4.6; 10.7), respectively. PK/PD results were as expected, with no difference between hemophilia subtypes for concizumab exposure, free tissue factor pathway inhibitor, thrombin generation, prothrombin fragment 1+2, and d-dimers. Concizumab was safe and well tolerated (no severe AEs, AE-related withdrawals, or thromboembolic events). Three patients had (very low to medium titer) ADA+ tests in each trial, with no observed clinical effect. These results support further development of concizumab as a daily prophylactic treatment in all hemophilia patients. These trials were registered at www.clinicaltrials.gov as #NCT03196284 and #NCT03196297., (© 2019 by The American Society of Hematology.)

Introduction: Ensuring hemostasis during invasive procedures is a challenge in patients with severe hemophilia A. This analysis evaluated efficacy and safety of BAY 94-9027, an extended-half-life recombinant factor VIII (FVIII), in the surgical setting., Materials and Methods: Patients participating in an open-label BAY 94-9027 clinical trial who underwent major surgery were included in the analysis. Investigator/surgeon assessment of hemostasis during surgery was the primary outcome. In addition, information about FVIII use, FVIII levels during perioperative period, bleeding complications and FVIII inhibitor development were collected., Results: Data were analyzed for 26 major surgeries (orthopedic, n = 21) in 20 patients aged 13-61 years. BAY 94-9027 provided effective hemostasis during all procedures. FVIII levels 6-8 h post preoperative infusion and prior to the first follow-up infusion were in the range expected to maintain protection in the major surgery setting. The median time from preoperative infusion to the first follow-up infusion (the first infusion administered after the preoperative infusion) was 12.33 (3.6-49.9) h. No intraoperative bleeding complications occurred, and no new inhibitors developed following any surgery., Conclusions: The results of the study demonstrate that BAY 94-9027 was efficacious and well tolerated in the treatment of patients undergoing major surgeries. Advantages of BAY 94-9027 include the potential for less frequent infusion and reduced factor consumption, which should simplify the management of patients during major surgery., (Copyright © 2019 The Authors.

Background: N8-GP is an extended half-life recombinant factor VIII developed for prophylaxis and treatment of bleeds in patients with hemophilia A., Objective: To assess pharmacokinetic (PK) characteristics of N8-GP in previously treated patients with severe hemophilia A, model the time spent at hemophilia thresholds of ≥1 and ≤5 IU/dL (moderate) or >5 IU/dL (mild) FVIII levels during N8-GP prophylaxis, and investigate the relationship between N8-GP half-life and von Willebrand factor (vWF)., Methods: PK assessments were obtained from patients with severe hemophilia A (FVIII < 1 IU/dL) participating in 4 clinical trials: pathfinder 1 (20-60 years); pathfinder 2 (12-17 and ≥18 years); pathfinder 5 (0-11 years), and pathfinder 7 (25-71 years). All PK profiles were assessed after washout and considered single-dose PK profiles. Pre- and postdose FVIII activity at steady state was measured at all visits., Results: From 69 patients, 108 PK profiles of N8-GP 50 IU/kg were assessed. Adults/adolescents received 50 IU/kg every 4 days, achieving mean trough levels of 3.0 IU/dL (95% confidence interval, 2.6-3.5, adults) and 2.7 IU/dL (1.8-4.0, adolescents). Children received 60 IU/kg twice weekly, leading to mean trough levels of 1.2 IU/dL (0.8-1.6, 0- to 5-year-olds) and 2.0 IU/dL (1.5-2.7, 6- to 11-year-olds). PK modeling predicted children dosed every 3 days and adults/adolescents dosed every 3 to 4 days would maintain FVIII levels >5 and >1 IU/dL for >80% and 100% of the time, respectively. N8-GP half-life correlated linearly with von Willebrand factor levels in adults/adolescents, less in children., Conclusions: Prophylaxis with fixed intervals (Q4D/twice weekly) and fixed weight-based dosing (50/60 IU/kg) ensured >1 IU/dL FVIII trough levels in both adults and children.

Background: Deficiency in coagulation factor VIII encoded by F8 results in the X-linked recessive bleeding disorder haemophilia A (HEMA). Here we describe the identification of a novel variant in the factor VIII gene, F8 , in an adult male patient with severe haemophilia A., Case Presentation: The patient was diagnosed in early childhood and subsequently co-infected with Hepatitis C and HIV acquired during early blood transfusion for haemophilia in the 1980ies. The identified F8 deletion, c.5411&#95;5413delTCT, p.F1804del lies within a conserved part of the molecule, is predicted by bioinformatic software to be deleterious by the loss of Phenylalanine, and has not been previously described in any database., Conclusion: This novel F8 deletion as a cause of haemophilia A did not result in generation of inhibitory antibodies to Factor VIII treatment and may have impact on (prenatal) diagnosis, genetic counselling, and treatment decisions in the affected family as well as in other families diagnosed with this F8 mutation. Finally, this novel mutation should be included in the panel of known genetic variants in F8 when searching for the genetic etiology in patients suspected of HEMA., Competing Interests: This study was approved by the Danish Reginal Ethics Committee (1–10–72-369-14). Moreover, the patient described provided his oral and written consent to participate.The patient provided written consent for publication of potentially-identifying information.The authors declare that they have no competing interests.Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

Objectives: In this 6-month open-label extension (OLE) of NCT01491035 (a 14-day, open-label, pharmacokinetic/safety lead-in study), the long-term safety and tolerability of vortioxetine (5-20 mg/day) were investigated in children and adolescents with a DSM-IV-TR™ diagnosis of depressive or anxiety disorder in the United States or Germany. The study also was designed to provide data to inform dose selection and titration in future pediatric studies with vortioxetine., Methods: Safety evaluations included spontaneously reported adverse events (AEs), the Columbia Suicide Severity Rating Scale (C-SSRS), and the Pediatric Adverse Events Rating Scale (PAERS; clinician administered). Clinical effectiveness was determined by Clinical Global Impressions. Comorbid attention-deficit/hyperactivity disorder was permitted, including concomitant use of stimulant medication (US sites only)., Results: Of the 47 patients who completed the lead-in period, 41 continued into the OLE. Most patients (n = 39 [95%]) continued their previous dose regimen. Twenty-one patients (51%) withdrew during the OLE; the most common primary reasons were administrative [n = 8], AEs [n = 4], and lack of efficacy [n = 3]. Thirty-five patients (85%) had ≥1 AE, 86% of which were mild or moderate in severity. Five patients (12%) reported a severe AE, none of which was considered related to study medication. The most common AEs (≥10%) were headache (27%), nausea (20%), dysmenorrhea (females; 19%), and vomiting (15%), with no relationship between AE intensity and age or dose. Five patients reported instances of suicidal ideation during the OLE, one of whom also reported this during the lead-in period. Two patients had nonsuicidal self-injurious behavior; one had a nonfatal suicide attempt. Throughout the study, there was a decrease over time in the incidence and intensity of AEs collected using the PAERS. Effectiveness assessment indicated a trend toward improvement based on numeric results., Conclusion: This OLE confirms the findings from the lead-in study, which concluded that a dosing strategy of 5-20 mg/day is safe, well tolerated, and suitable for future clinical studies of vortioxetine in pediatric patients.

Background: The positive effects of factor treatment of hemophilia are well established, but the long-term outcomes are not well documented. This panel study evaluated changes in bleeding frequency, joint mobility, physical function, and symptoms in Danish patients with moderate to severe hemophilia A or B over 24 years., Methods: Three anonymous surveys were conducted in 1988, 2001, and 2012 targeting Danish patients with moderate to severe hemophilia, and the study participants, respectively, were 128, 156, and 164 male patients with hemophilia (PWH). The number of bleeding episodes, the use of factor concentrate, comorbidities, joint mobility, physical function, and symptoms were evaluated by means of self-reporting. Trends over time were analyzed using ordinal and multinomial logistic-regression models controlling for age group., Results: The proportion of PWH in the oldest age group (55-88 years) increased from 4% in 1988 to 18% in 2012. In 1988, a high risk of bleeding episodes was primarily found in the age group of 16-34 years. In 2012, a high risk was primarily found in the age group of 35-54 years. Joint mobility and physical function increased significantly from 1988 to 2012 but showed a noticeable decrement in the older age groups, even in 2012. Pain in the extremities, anxiety, and depression decreased significantly, but back pain increased. No significant changes were found for 7 other symptoms., Conclusions: Significant improvements in joint mobility and physical function have occurred over the last 24 years, but PWH > 35 years still experience a decline in these areas with age. This decline underscores the importance of life-long treatment and continuous rehabilitation of PWH., (© 2018 S. Karger AG, Basel.)

Objective: The primary objectives of this study were to evaluate the pharmacokinetics (PK) and tolerability of single and multiple doses of vortioxetine in children and adolescents with a depressive or anxiety disorder and to provide supportive information for appropriate dosing regimens for pediatric clinical trials., Methods: This prospective, open-label, multinational, multisite, multiple-dose trial enrolled 48 patients (children and adolescents; 1:1 ratio) divided into 8 cohorts (4 adolescent and 4 child), with each cohort including 6 patients. The cohorts in each age group were assigned to receive one of four dosing regimens: vortioxetine 5, 10, 15, or 20 mg q.d. for 14 days. The total treatment period lasted 14-20 days with patients in the higher dose cohorts uptitrated over 2-6 days. Plasma samples for PK analysis were obtained on the first and last days of dosing., Results: Among children and adolescents, respectively, 62% and 92% had depression and 58% and 33% had anxiety disorder. Comorbid attention-deficit/hyperactivity disorder (ADHD) was present in 50% of children and 38% of adolescents. After 14 days q.d. at the target dose, the PK of vortioxetine concentrations was generally proportional to the dose in both age groups. Exposure, as assessed by maximum plasma concentrations and area under the plasma concentration-time curve from time 0 to 24 hours, was 30%-40% lower in adolescents than in children. There was no significant relationship between sex, height, or ADHD diagnosis and PK parameters. Most adverse events were mild in severity and consistent with those seen in adults., Conclusion: The results suggest that the dosages of vortioxetine evaluated (5-20 mg q.d.; approved for treatment in adults) and the uptitration schedule used are appropriate for pediatric efficacy and safety trials.

Essentials Recombinant factor VIII BAY 94-9027 conjugates in a site-specific manner with polyethylene glycol. BAY 94-9027 was given to patients with severe hemophilia A as prophylaxis and to treat bleeds. BAY 94-9027 prevented bleeds at dose intervals up to every 7 days and effectively treated bleeds. BAY 94-9027 treatment was mainly well tolerated and no patient developed factor VIII inhibitors. Click to hear Dr Tiede's perspective on half-life extended factor VIII for the treatment of hemophilia A SUMMARY: Background BAY 94-9027 is a B-domain-deleted prolonged-half-life recombinant factor VIII (FVIII) that conjugates in a site-specific manner with polyethylene glycol. Objective Assess efficacy and safety of BAY 94-9027 for prophylaxis and treatment of bleeds in patients with severe hemophilia A. Patients/methods In this multinational, phase 2/3, partially randomized, open-label trial, men aged 12-65 years with FVIII < 1% and ≥ 150 exposure days to FVIII received BAY 94-9027 for 36 weeks on demand or prophylactically at intervals determined following a 10-week run-in period on 25 IU kg -1 body weight two times per week. Patients with > 1 bleed during the run-in subsequently received 30-40 IU kg -1 two times per week; patients with ≤ 1 bleed were eligible for randomization to every-5-days (45-60 IU kg -1 ) or every-7-days (60 IU kg -1 ) prophylaxis (1 : 1) for 26 additional weeks until randomization arms were filled. Patients who were eligible but not randomized continued twice-weekly prophylaxis. The primary efficacy outcome was annualized bleeding rate (ABR). Results The intent-to-treat population included 132 patients (prophylaxis, n = 112; on demand, n = 20). Median ABR (quartile [Q1; Q3]) for patients treated two times per week who were not eligible for randomization (n = 13) improved after dose increase (17.4 [14.3; 26.0] to 4.1 [2.0; 10.6]). Median ABR for patients randomized to every-5-days treatment (n = 43) was 1.9 (0; 4.2), similar to patients eligible for randomization but who continued treatment two times per week (n = 11). Median ABR for 32/43 patients (74%) who continued every-7-days prophylaxis until study end was 0.96 (0.0; 4.3). Six hundred and thirty-six of 702 bleeds (90.6%) were controlled with ≤ 2 infusions. No patient developed a FVIII inhibitor. Conclusions BAY 94-9027 prevented bleeding across three individually tailored dose regimens and was effective for treatment of bleeds., (© 2016 The Authors.

Turoctocog alfa pegol (N8-GP) is a novel glycoPEGylated extended half-life recombinant factor VIII (FVIII) product developed for prophylaxis and treatment of bleeds in patients with haemophilia A, to enable higher activity levels with less frequent injections compared with standard FVIII products. This phase III (NCT01480180), multinational, open-label, non-randomised trial evaluated the safety and clinical efficacy of N8-GP when administered for treatment of bleeds and for prophylaxis, in previously treated patients aged ≥12 years with severe haemophilia A. Patients were allocated to receive N8-GP for prophylaxis or on-demand treatment for up to 1.8 years. Patients on prophylaxis were administered one dose of 50 IU/kg of N8-GP every fourth day. Bleeds were treated with doses of 20-75 IU/kg. Total exposure to N8-GP in the trial was 14,114 exposure days (159 patient-years). For the prophylaxis arm (n=175), the median annualised bleeding rate (ABR) was 1.33 (interquartile range, 0.00-4.61), the mean ABR was 3.70 (95 % confidence interval 2.94-4.66) and 70 (40 %) patients had no bleeds during the trial. Across treatment arms, 83.6 % of bleeds resolved with one injection and 95.5 % with up to two injections. N8-GP had a favourable safety profile and was well tolerated. The frequency and types of adverse events reported were as expected in this population. One patient developed inhibitory antibodies against FVIII (≥0.6 Bethesda units [BU]) after 93 N8-GP exposure days. No clinically significant safety concerns were identified and N8-GP was effective for prophylaxis and treatment of bleeds in previously treated patients.

Objective: This randomised, double-blind, 12-week study compared efficacy and tolerability of flexible-dose treatment with vortioxetine(10-20 mg/day) versus agomelatine (25-50 mg/day) in major depressive disorder patients with inadequate response to selective serotonin reuptake inhibitor (SSRI)/serotonin-noradrenaline reuptake inhibitor (SNRI) monotherapy., Methods: Patients were switched directly from SSRI/SNRI to vortioxetine or agomelatine. Primary endpoint was change from baseline to week 8 in the Montgomery-Åsberg Depression Rating Scale (MADRS) total score analysed by mixed model for repeated measurements, using a noninferiority test followed by a superiority test. Secondary endpoints included response and remission rates, anxiety symptoms(Hamilton Anxiety Rating Scale), Clinical Global Impression, overall functioning (Sheehan Disability Scale), health-related quality of life(EuroQol 5 Dimensions), productivity (work limitation questionnaire) and family functioning (Depression and Family Functioning Scale)., Results: Primary endpoint noninferiority was established and vortioxetine (n = 252) was superior to agomelatine (n = 241) by 2.2 MADRS points (p<0.01). Vortioxetine was also significantly superior in response and remission rates at weeks 8 and 12; MADRS, Hamilton Anxiety Rating Scale, Clinical Global Impression, Sheehan Disability Scale and EuroQol 5 Dimensions scores at week 4 onwards; work limitation questionnaire at week 8 and Depression and Family Functioning Scale at weeks 8 and 12. Fewer patients withdrew because of adverse events with vortioxetine (5.9% vs 9.5%). Adverse events (incidence ≥5%) were nausea, headache, dizziness and somnolence., Conclusions: Vortioxetine was noninferior and significantly superior to agomelatine in major depressive disorder patients with previous inadequate response to a single course of SSRI/SNRI monotherapy. Vortioxetine was safe and well tolerated.

Venous malformations (VM) represent vascular developmental errors. They are low-flow lesions composed of ectatic vessels that histologically and morphologically are similar to veins. Episodic thromboses commonly occur in VM. Moreover, pulmonary emboli, sudden death and chronic thromboembolic pulmonary hypertension have been described in children and adults with extensive VM. This article discusses the management and treatment of patients with extensive VM.

Klippel-Trénaunay syndrome is characterized by the venous varicosities, ipsilateral cutaneous capillary malformations, and bony/soft-tissue overgrowth. Potential complications such as hypercoagulability, thrombosis and pulmonary embolism have been casuistically reported. Here, we describe a child with Klippel-Trénaunay syndrome complicated by a pulmonary embolism leading to sudden death.

Recurrent bleeding into joints initiates a sequence of events leading to a progressive joint damage in people with severe haemophilia. This is a continuous process during childhood and adolescence, therefore joint abnormalities may be minimal on physical examination in very young children - even those receiving on-demand treatment. The aim of our study was to quantify the burden of arthropathy in Lithuanian patients who had been treated exclusively by on-demand substitution and compare their physical joint health with age-matched Danish patients who received prophylaxis from an early age. Boys, aged 4-17 years, with severe haemophilia and no signs of inhibitors were included in the study. Joint outcome based on the Haemophilia Joint Health Score (HJHS) was analysed in two different treatment groups and compared within the matched pairs. In total, 32 (16 in each treatment group) patients were enroled. A total of 192 joints were evaluated. Joint status according to treatment strategy was strikingly different: 27.4 for on-demand vs. 3.3 for prophylaxis (<0.001) group. Significance of the difference in joint status comparing different treatment strategies was equally strong both in younger (4-9 years) and older (10-17 years) patient groups: 2.2 vs. 12.5 (P = 0.0002) and 3.9 vs. 36.3 (P < 0.0001) respectively. The results further demonstrate the unequivocal effect of prophylaxis on joint status and give an insight into early and late manifestations of joint impairment based on the HJHS in haemophilia patients with treatment on-demand compared with joint changes that may develop over the time with the preventative treatment., (© 2012 Blackwell Publishing Ltd.)

Background: Peristomal skin problems are common and are treated by a variety of health professionals. Clear and consistent communication among these professionals is therefore particularly important. The Ostomy Skin Tool (OST) is a new assessment instrument for the extent and severity of peristomal skin conditions. Formal tests of reliability and validity are necessary for its use in clinical practice, research, and education., Objectives: To estimate inter- and intra nurse assessment variability of the OST and validity by comparison to a 'gold standard' (GS) defined by an expert panel., Methods: Thirty photographs of peristomal skin were presented twice to 20 ostomy care nurses--10 from Denmark (DK) and 10 from Spain (ES)--to determine intra- and inter nurse assessment variability. The same photographs were presented to an international group of experts (dermatologist and ostomy care nurses), to establish a GS for comparison and validation of the results., Results: A high intra-nurse assessment agreement, κ=0·84, was found with no differences in the intra-nurse assessments from the two groups of nurses (DK and ES). The inter-nurse assessment agreement was 'moderate to good', κ=0·54, with the agreement between the experts higher, κ=0·70. A high correlation between the scores from the nurses and the GS were seen in the lower part of the two scales [Discoloration, Erosion, Tissue overgrowth (DET) score<7)]., Conclusion: The study supported the validity of the OST. It is suggested that a categorical scale can be used to illustrate the severity of the DET scores., (© 2011 The Authors. BJD © 2011 British Association of Dermatologists.)

Assay discrepancy in mild haemophilia, here defined by a significantly higher factor VIII (FVIII):C response by the one-stage procoagulant assay as compared with a two-stage enzymatic method, has repeatedly been reported in literature. The purpose of this study was to determine the overall prevalence of this phenomenon amongst mild haemophilia families from a population of 2.95 million inhabitants in the Western Danish region. Information was collected retrospectively through a thorough search of archives of the National Haemophilia Centre in Aarhus. We identified 109 patients with mild haemophilia A amongst whom 92 were eligible to enter the study. These represent a total of 53 unrelated families. Our data illustrate that this assay discrepancy pattern is found quite frequently amongst our mild haemophilia A families. While the ratio of FVIII:C chromogenic/FVIII:C clot values was quite consistent amongst patients belonging to same family pattern, ratios in the entire cohort of families ranged from 0.18 to 1.00. Selecting a cut-off level for the FVIII:C chromogenic/FVIII:C clot ratios at 0.7, 0.6 and 0.5, respectively, we found that 38 (72%), 27 (51%) and 19 (36%) of families, respectively, displayed this assay discrepancy. In 10 patients, the FVIII:C chromogenic level was inside the category of moderate haemophilia at >0.01-<0.05 IU mL(-1), pointing to a class-shift in the biochemical phenotype. In conclusion, our data illustrate a substantial prevalence of the assay discrepancy phenomenon amongst mild haemophilia A patients in our geographical area.

Extensive surgery and massive tissue trauma are often associated with severe bleeding. We present retrospective data on the use of recombinant factor VIIa in haemostatic emergencies in13 non-hemophilia patients with uncontrolled bleeding. Recombinant factor VIIa was administered in doses ranging from 16 mug/kg bodyweight to 60 microg/kg bodyweight. Blood loss during 24 h before and after the infusion was registered, showing that 10 out of 13 patients (77%) had a 70% or greater reduction in transfusion requirement decreasing significantly in mean from 28.1 to 9.9 red blood cell units. Coagulation parameters were studied in blood samples collected 10 min before and 10-15 min after the injection of recombinant factor VIIa. Factors VII:C, II:C, and X:C increased significantly while the activated partial thromboplastin time, platelet numbers, and concentration of fibrinogen and D-dimers were unchanged. The dose of rFVIIa correlated significantly with the rise in factor X:C and inversely with transfusion requirements. Dynamic clot velocity of whole blood was recorded before and after rFVIIa infusion in four patients. Judged from red blood cell usage no improvement in haemostasis was seen in one patient suffering thrombocytopenia and low fibrinogen. This patient died 6 h after recombinant factor VIIa infusion, and three other patients died before 1 month. None of the fatalities appeared to be related to recombinant factor VIIa usage. No thromboembolic complications were seen. In conclusion, 12 out of 13 patients survived the first 24 h after treatment with relatively low doses of recombinant factor VIIa for large-scale bleeding. Recombinant factor VIIa was well tolerated and safe in these non-hemophilia patients. With quite low doses of recombinant factor VIIa (

Background: The objective was to test whether an association between school connectedness and smoking exists among Danish school children, and if so, to examine whether parental smoking attitude and parental smoking behaviour influenced this association., Methods: Data were collected by the Danish contribution to the cross-national study Health Behaviour in School-Aged Children (HBSC) 1998. Analyses were performed on questionnaire-based data from 1537 students at grade nine from a random sample of schools in Denmark., Results: An independent inverse association was found between school connectedness and smoking among both boys and girls. Parents' attitude to their children's smoking significantly modified this association among boys. Among girls the modifying effect was less marked. Neither among boys nor girls did parental smoking behaviour significantly modify the association between school connectedness and smoking, although a modifying tendency was observed among girls., Conclusions: The smoking behaviour of Danish adolescents may be influenced by complicated interactions of varying sets of experienced smoking norms, and any research project or preventive programme focusing on the influence of school life on adolescent smoking behaviour needs to consider the family smoking norms. Additionally, the results stress the important role of gender by indicating that the smoking behaviour of girls may be more sensitive to restricting social influences than the smoking behaviour of boys.

In this study, we present a case of late-puerperal onset of thrombohemorrhagic complications in a 33-yr-old woman with known antiphospholipid syndrome (APS) and heterozygosity for factor V Leiden gene mutation. Antithrombotic prophylaxis with low-molecular-weight (LMW) heparin was given since the 12th gestational week. Pregnancy and cesarean delivery were uncomplicated. Five weeks postpartum, the patient developed a severe hemorrhagic diathesis with marked thrombocytopenia accompanied by vaginal, nasal and cutaneous bleeding. A variety of autoimmune phenomena were also detected, partly at clinical presentation and partly later on, despite ongoing steroid treatment. Platelet counts recovered to normal values within a few weeks secondary to high-dose steroids and intravenous immunoglobulin administration. An ultrasound of both legs, performed because of persistent complaint of moderate calf pain, revealed bilateral deep venous thromboses (DVT). The clinical and biochemical findings were not consistent with thrombotic thrombocytopenic purpura (TTP), heparin-induced thrombocytopenia (HIT) or the 'hemolysis, elevated liver enzymes and low platelet syndrome' (HELLP). The diagnostic criteria for systemic lupus erythematosus (SLE) were not fulfilled either. The complex of thrombohemorrhagic complications and autoimmune phenomena seen in this case is unusual and not previously described in the late puerperal stage of APS-related pregnancies.

In the clinical setting, patients suffering from haemophilia are classified according to the residual level of the deficient coagulation factor. Patients suffering from the severe form of haemophilia (critical factor level <0.01 IU mL-1) display some heterogeneity in their tendency to bleeding despite the uniform factor level. Utilizing a new thrombelastographic method in which coagulation is activated by very small amounts of tissue factor and where resulting data are processed with new software, we studied the whole blood coagulation profile in 11 patients with severe haemophilia A and 11 patients with moderate haemophilia. In both groups of patients, we found a considerable degree of heterogeneity in the coagulation signal. In moderate haemophilia with factor VIII (FVIII):C levels between 0.01 and 0.05 IU mL-1, variance was expected, whereas a quite substantial diversity had not been forecasted in patterns of the whole blood coagulation profiles in patients with the severe form of haemophilia A. Ex vivo substitution to patient's blood to reach various theoretical levels of recombinant factor VIII (rFVIII) revealed that the coagulation response to FVIII supplementation varied substantially. In some severely affected patients levels of FVIII:C close to 0.05 IU mL-1 was sufficient to normalize the coagulation profile, while others required a dose giving >0.50 IU mL-1 of FVIII to achieve a normal whole blood clotting profile. In conclusion, our study revealed that severe haemophilia A seems not to be a single entity, but rather several different clinical and biochemical phenotypes, and that the response to added FVIII varies amongst patients.

Objective: To determine whether adolescent smoking behaviour is associated with their perceived exposure to teachers or other pupils smoking at school, after adjustment for exposure to smoking at home, in school, and best friends smoking., Design: Logistic regression analysis of cross sectional data from students in Denmark., Subjects: 1515 grade 9 students (mean age 15.8) from 90 classes in 48 Danish schools., Outcome Measure: Self reported smoking behaviour; daily smoking and heavy smoking, defined as those smoking more than 20 cigarettes per week., Results: Of the students in this study, 62% of boys and 60% of girls reported being exposed to teachers smoking outdoors on the school premises. The proportion of boys and girls reporting to have been exposed to teachers smoking inside the school building were 86% and 88%, respectively. Furthermore, 91% of boys and 92% of girls reported that they had seen other students smoking outdoors on the school premises. Adolescents' perceived exposure to teachers smoking outdoors on the school premises was significantly associated with daily smoking, having adjusted for sex, exposure to teachers smoking indoors at school and pupils smoking outdoors at school, as well as the smoking behaviour of mother, father, and best friend (odds ratio (OR) 1.8, 95% confidence interval 1.2 to 2.8). Adolescents' perceived exposure to teachers smoking inside the school building was not associated with daily smoking (OR 0.9, 95% CI 0.5 to 1.6) and perceived exposure to pupils smoking outdoors was not associated with daily smoking (adjusted OR 1.5, 95% CI 0.5 to 4.4). There were similar findings with heavy smoking as the outcome variable., Conclusions: Teachers smoking during school hours is associated with adolescent smoking. This finding has implications for future tobacco prevention strategies in schools in many countries with liberal smoking policies where it might provide support for those working to establish smokefree schools.

Objective: To evaluate factors with possible influence on the renal outcome in patients with lupus nephritis but without chronic renal insufficiency (CRI)., Methods: Renal biopsies from 94 patients were re-assessed with regard to WHO class, activity, chronicity and tubulointerstitial indices without knowledge of clinical features. The outcome parameters were CRI defined as irreversibly increased serum creatinine and renal end stage disease., Results: The risk ratios (RR) of developing CRI were 2.6 for active urinary sediment, 3.1 for hyaline thrombi and 7.3 for glomerular leukocyte exudation. The RR of renal end stage disease was 5.0 when the duration of renal disease exceeded one year at the time of biopsy and 4.3 when biopsy disclosed a class IV lesion. Glomerular sclerosis was also associated to renal end stage disease., Conclusion: Early renal biopsy and the abovementioned signs of active renal disease carry prognostic information that may have significant therapeutic implications.

A multicentre cohort of 513 clinic attenders with systemic lupus erythematosus (SLE) was retrospectively identified, representing 4185 patient-years of follow-up. Expected numbers of death were calculated by means of age- and sex-specific mortality rates of the general Danish population. The observed number of deaths was 122. The survival rates were 97%, 91%, 76%, 64% and 53% after 1, 5, 10, 15, and 20 years respectively. The overall mortality rate was 2.9% per year (95% CI 2.4-3.5), and the standardized mortality rate (SMR) was 4.6 (95% CI 3.8-5.5). The causes of death included active SLE (n = 19), end stage organ failure due to SLE (n = 16), infections (n = 25), malignancy (n = 9), cardiovascular disease (n = 32), and other causes (n = 21). SLE was directly related to one third of the excess mortality. In conclusion, SLE patients in the present cohort had a 4.6-fold increased mortality compared with the general population and half of the deaths were caused by SLE manifestations or infections, especially in young patients during the early period of the disease.

In this Danish multicentre study, predictive clinical factors of mortality and survival were calculated for 513 patients with systemic lupus erythematosus (SLE), 122 of whom died within a mean observation period of 8.2 years equalling a mortality rate of 2.9% per year. Survival rates were 97%, 91%, 76% and 64% after 1, 5, 10 and 15 years, respectively. The direct causes of death included SLE (n = 35), infections (n = 25), malignancy (n = 9), cardiovascular disease (n = 32) and other causes (n = 21). Uni- and multivariate analyses of survival and mortality were performed for all deaths and for SLE-related deaths. Azotaemia (one-fifth of the patients) was a strong predictor of increased overall and SLE-related mortality, but nephropathy per se (one-half of the patients) and large proteinuria (one-sixth of the patients) were unrelated to survival. Haemolytic anaemia had a significant negative influence on survival related to mortality caused by infections. Diffuse central nervous system disease and myocarditis were related to increased SLE-related mortality, whereas photosensitivity predicted a decreased mortality. Non-fatal infections and thrombotic events predicted a decreased overall survival. Since 1980 the mortality caused by SLE manifestations has decreased significantly.

A Danish multicentre study was undertaken of the manifestations, infections, thrombotic events, survival and predictive factors of survival in 513 Danish patients with systemic lupus erythematosus (SLE) according to the 1982 classification criteria of the American College of Rheumatology. The mean duration of follow-up was 8.2 years from diagnosis and 12.8 years from first symptom. This paper describes the most common clinical and laboratory manifestations and their relationship to sex and age at the time of onset and diagnosis. Cluster analysis revealed three clinically defined clusters at the time of disease onset. Cluster 1 (57% of patients) consisted of relatively elderly patients without nephropathy or malar rash, but with a high prevalence of discoid lesions. Cluster 2 (18%) consisted of patients with nephropathy, a third of whom also developed serositis and lymphopenia. The patients of the third cluster (25%) all had malar rash and half were photosensitive. Follow-up showed that the patients of cluster 2 developed azotaemia, large proteinuria, arterial hypertension and myositis significantly more often than did the rest of the patients, but the mortality was not increased. The risk of developing renal end-stage disease was highest in men with early-onset disease.

Chronic central pain is a frequent complication after spinal cord injury. Anticonvulsant drugs, among them valproate, have been recommended for treatment. In this paper we conducted a double-blind, cross-over study comparing valproate and placebo for severe chronic central pain. During the study, serum concentration of valproate, pain and side effects were registered and the dose was adjusted according to these. No significant analgesic effects of valproate could be demonstrated although serum concentration and dose reached a high level. Few studies of pain following spinal cord injury exist and we recommend that further studies be performed.

Objective: To develop a methodology for translating the McGill Pain Questionnaire (MPQ) into a Danish version, and to make comparisons to studies of patients speaking other languages., Design: Finding suitable Danish adjectives using the same methodology as that in the original MPQ. Comparison of Danish descriptors to the words in the English version of MPQ. Survey in healthy subjects and patients with rheumatoid arthritis (RA) and fibromyalgia (F)., Setting: The general public and hospital outpatients., Patients: A random sample of 186 healthy volunteers, 20 patients with rheumatoid arthritis and 41 patients with fibromyalgia., Main Outcome Measures: Danish words translated as closely as possible to the descriptors in the original McGill Pain Questionnaire. A pain-assessment instrument making international pain description possible., Results: A Danish version of the McGill Pain Questionnaire was developed with scale values of Danish descriptors not differing more than 5 x SEM from the 'patient' words in the English version. The subdivision into classes and subclasses was respected. In the reliability experiment, the same rank values were found in 85% of subclasses. In a study using two experimental pain stimulus intensities, seven of 10 subjects obtained higher MPQ scores following the high-intensity stimulus. In the clinical study, the pain profiles of patients with RA and F in English, Italian, and Danish patients were almost the same., Conclusion: The present methodology of translating the McGill Pain Questionnaire permits comparison of studies from English-speaking and non-English-speaking populations, thus facilitating international research exchange.
