- Introduction People with haemophilia (PwH) may experience symptoms of haemophilia-related pain, depression or anxiety, which can negatively impact health-related quality of life. Aim To obtain the perspective of PwH and treaters from Sweden, Finland and Denmark on the management of haemophilia-related pain, depression and anxiety using cross-sectional survey data from the MIND study (NCT03276130). Methods PwH or their caregivers completed a survey about experiences of pain, depression and anxiety related to haemophilia, and the standard EQ-5D-5L instrument. Five investigators at haemophilia treatment centres (HTC) were sent a complementary survey containing questions about the management of pain and depression/anxiety. Results There were 343 PwH (mild: 103; moderate: 53; severe: 180; seven lacking severity information) and 71 caregiver responses. Experience of pain in the last 6 months was reported by 50% of PwH respondents and 46% of caregiver respondents. Anxiety/depression was reported by 28% of PwH respondents. Reporting of pain and anxiety/depression was associated with disease severity. Whilst 62% of PwH who had experienced pain at any time point (n = 242) felt this was adequately addressed and treated at their HTC, only 24% of those who had experienced depression/anxiety (n = 127) felt this was adequately addressed. Disease severity was negatively associated with EQ-5D-5L utility value (p < .001). In the HTC survey, 4/5 and 2/5 agreed that pain and depression/anxiety, respectively, are adequately addressed. Conclusions Pain and depression/anxiety occur more frequently with increasing haemophilia severity, with negative impacts on health-related quality of life. PwH with depression/anxiety or unaddressed pain could benefit from improved management strategies.

- IntroductionGood health-related quality of life (HRQoL) is an important goal in the treatment of persons with haemophilia B (PwHB). Studies focusing on this population are limited, however, and data are insufficient. AimTo assess the HRQoL in PwHB and to compare this to data on persons with haemophilia A (PwHA), as well as to evaluate the impact of joint health on HRQoL and to identify areas of insufficient care. MethodsThe B-NORD study enrolled persons with severe haemophilia B and matched controls with haemophilia A. HRQoL was assessed using the EQ-5D-3L questionnaire and joint health using Haemophilia Joint Health Score 2.1 (HJHS). ResultsThe EQ-5D-3L was completed by 63 PwHB and 63 PwHA. Mobility problems were reported by 46% of PwHB and 44% of PwHA, pain/discomfort by 62% and 56%, and anxiety/depression by 33% and 17%, respectively. No significant difference was observed between PwHA and PwHB in EQ-5D profiles, level sum score, EQ-5D index (PwHB mean .80, PwHA mean .83, p = .24), or EQ VAS score (PwHB: mean 70, PwHA: mean 77, p = .061). Linear regression adjusted for age demonstrated that an increase in HJHS score was associated with a significant decrease in both EQ-5D index (B -.003, R-2 .22) and EQ VAS score (B -.37, R-2 .17). ConclusionDespite the majority of patients being treated with prophylaxis, impaired HRQoL was reported in both PwHB and PwHA. No differences in HRQoL were found between the two groups. Impaired joint health had a significant negative impact on HRQoL.

- Introduction: The development of inhibitory antibodies (inhibitors) in persons with hemophilia B (PwHB) causes significant morbidity. Data on the impact of the F9 variant and immune tolerance induction (ITI) outcome are limited.The aim of this study was to investigate the presence of neutralizing and non-neutralizing antibodies (NNA) in severe hemophilia B (HB) and to evaluate ITI outcome and complications in relation to the pathogenic F9 variant.Materials and methods: Persons with severe HB in the Nordic countries were enrolled and information on F9 variants, inhibitors, ITI and complications were collected. Analyses of anti-FIX antibodies with a fluorescence -immunoassay (xFLI) and an ELISA method were conducted.Results: Seventy-nine PwHB were enrolled. Null variants were seen in 33 (42 %) PwHB and 12 (15 %) had a current or former inhibitor. Eleven (92 %) of the inhibitor patients had experienced allergic manifestations and three (25 %) nephrotic syndrome. Of 10 PwHB with at least one ITI attempt, eight (80 %) were considered tolerant at enrolment. Immunosuppression was included in seven of eight successful or partially successful at-tempts. Five PwHB had at least one ITI failure before a successful or partially successful ITI. No NNA could be identified.Conclusion: A high proportion of severe F9 gene defects among persons with severe HB in the Nordic countries may explain the observed relatively high prevalence of inhibitors. ITI success was independent of the F9 variant and attained despite allergic manifestations and previous ITI failures. Inclusion of immunosuppression tenta-tively enhances the chances of ITI success. No NNA were observed.

- Introduction Perioperative dosing recommendations vary across Nordic haemophilia treatment centres (HTCs) for extended half-life (EHL) factor concentrates in haemophilia A/B (HA/HB) patients. Aim To summarise Nordic real-world surgical experiences with EHL recombinant factor VIII/IX Fc (rFVIIIFc/rFIXFc) fusion proteins using retrospective data from clinical records at four HTCs in Finland, Sweden and Norway. Methods Factor dosing and surgical outcomes were recorded from HA/HB patients who underwent surgery and were treated with rFVIIIFc/rFIXFc. Perioperative factor dosing regimens were clinician-determined based on local practises. Results Twenty five surgeries were performed on 20 patients, all covered by bolus injections except one minor HA surgery; eight minor surgeries were in paediatric patients. Median preoperative rFVIIIFc dose for major HA surgeries (n = 8) was 48 IU/kg (range: 35-57), with total consumption up to Day 14 of 427 IU/kg (196-568). For the two major HB surgeries (in one patient), preoperative rFIXFc doses were 50 IU/kg and 20 IU/kg; total consumption up to Day 14 was 130 IU/kg and 40 IU/kg. Median preoperative rFVIIIFc/rFIXFc bolus doses for minor HA (n = 10) and HB (n = 4) surgeries were 50 IU/kg (24-79) and 47 IU/kg (40-71), with total consumption up to Day 5 of 138 IU/kg (49-404) and 100 IU/kg (43-125), respectively. Intraoperative and postoperative haemostatic responses were rated as at least good/excellent for 24/25 surgeries, with bleeding episodes reported in only three surgeries. Conclusion Nordic real-world experiences suggest that EHL products can be used safely and effectively for peri-operative haemostasis. Further research is required to develop local dosing guidelines for optimised treatment schedules.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Data on the prevalence of hypertension and cardiovascular diseases (CVD) among persons with haemophilia (PWH) vary. Sweden has a long tradition of maintaining population-based data registries, and there is extensive follow-up of haemophilia patients due to the use of prophylaxis over decades. We evaluated the prevalence of these diseases among Swedish PWH compared to matched controls using a longitudinal study design. Methods: Data were obtained from the National Patient Registry and linked to records of persons with haemophilia enrolled in the haemophilia centres. For each subject, five gender and age matched controls were identified. Results: We identified 193 (19.7%) diagnoses of hypertension in PWH born in 1978 or earlier over >= 30 years compared with 550 (11.2%) among controls. The median ages and interquartile ranges were 60.0 (42.8, 69.9) and 57.2 (42.6, 70.6) years. The hazard rate (HR) for hypertension, PWH vs. controls, was 2.1, 95% CI: [1.8; 2.5], p < 0.001. The findings were similar in subgroup analyses of patients with non-severe and severe haemophilia with or without HIV and/or viral hepatitis. Angina pectoris was diagnosed in 69 (4.8%) of patients censored at age 75 compared with 311 (4.3%) in controls, and myocardial ischemia in 84 (5.9%) compared with 442 (6.2%). As a cause of death, the HR for myocardial ischemia, comparing PWH and controls, was 0.58, 95% CI: [0.42, 0.80], p = 0.001. Conclusion: Our data support an increased prevalence of hypertension among persons with haemophilia. The prevalence of CVD seems to be similar to that of controls, but with lower mortality.

- This prospective Phase II study is the first to assess the feasibility and efficacy of maintenance 5-azacytidine for older patients with high-risk myelodysplastic syndrome (MDS), chronic myelomonocytic leukaemia and MDS-acute myeloid leukaemia syndromes in complete remission (CR) after induction chemotherapy. Sixty patients were enrolled and treated by standard induction chemotherapy. Patients that reached CR started maintenance therapy with subcutaneous azacytidine, 5/28 d until relapse. Promoter-methylation status of CDKN2B (P15 ink4b), CDH1 and HIC1 was examined pre-induction, in CR and 6, 12 and 24 months post CR. Twenty-four (40%) patients achieved CR after induction chemotherapy and 23 started maintenance treatment with azacytidine. Median CR duration was 13.5 months, >24 months in 17% of the patients, and 18-30.5 months in the four patients with trisomy 8. CR duration was not associated with CDKN2B methylation status or karyotype. Median overall survival was 20 months. Hypermethylation of CDH1 was significantly associated with low CR rate, early relapse, and short overall survival (P = 0.003). 5-azacytidine treatment, at a dose of 60 mg/m(2) was well tolerated. Grade III-IV thrombocytopenia and neutropenia occurred after 9.5 and 30% of the cycles, respectively, while haemoglobin levels increased during treatment. 5-azacytidine treatment is safe, feasible and may be of benefit in a subset of patients.

Tidskriftsartikel (refereegranskat)abstract
- Background: Pain is a common feature of hemophilia, but prevalence of depression and anxiety is less studied. Registry data on prescription drugs can provide an objective measure of the magnitude of these complications. Objectives: To identify treatment patterns of prescribed pain, antidepressant, and antianxiety medications compared with those of matched controls in 4 Nordic countries. Methods: The MIND study (NCT03276130) analyzed longitudinal individual-level national data during 2007-2017. People with hemophilia (PwH) were identified from National Health Data Registers by diagnosis or factor replacement treatment and compared with population controls. Three subgroups were defined by the use of factor concentrates and sex (moderate-to-high factor consumption (factor VIII [FVIII] use of ≥40 IU/kg/week or FIX use of ≥10 IU/kg/week), low factor consumption, and women including carriers). Results: Data of 3246 PwH, representing 30,184 person-years, were analyzed. PwH (including children and adults) used more pain, depression, and anxiety medications compared with controls. This was most accentuated in the moderate-to-high factor consumption group and notably also observed in men with low factor consumption and women including carriers, usually representing a milder phenotype. A higher opioid use was observed across all age groups: 4- to 6-fold higher in the moderate-to-high factor consumption group and 2- to 4-fold higher in the low factor consumption group. Conclusion: The consistent higher use of pain, depression, and anxiety medications among PwH compared with population controls, regardless of age, sex, or factor consumption, in broad national data suggests a need for improved bleed protection and hemophilia care for all severities including mild hemophilia.

- Objective: Anaemia in low-risk myelodysplastic syndromes (MDS) is associated with reduced quality of life (QoL). Response to treatment with erythropoietin +/- granulocyte colony-stimulating factor (G-CSF) is associated with improved QoL, but whether transfusion therapy with higher haemoglobin (Hb) target levels has similar effects is unknown. The objective for this prospective phase II Nordic multicentre trial was to assess QoL, response rate and physical function in elderly anaemic MDS patients treated to a target Hb level of andgt; 120 g /L. Methods: Thirty-six elderly patients with low-and intermediate-1 risk MDS received darbepoetin (DA) 300 mu g/wk, with the addition of G-CSF if no response. If the Hb target was reached at 16 wk, treatment was maintained until week 26. Remaining patients were transfused to reach the target level for at least 8 wk. Results: Twenty-seven patients completed the study. Response rate to DA +/- G-CSF was 67% in evaluable patients and 56% according to intention to treat. Eighteen patients reached the target Hb level according to protocol. QoL scores for fatigue, dyspnoea, constipation, and physical, role and social functioning improved significantly during study, with similar results for transfused and untransfused patients. Maintaining Hb andgt; 120 g /L did not confer a higher transfusion rate, once the target was reached. In two of fourteen patients, magnetic resonance imaging T2* indicated cardiac iron overload, however, without association with ferritin levels. Conclusions: In elderly anaemic MDS patients, an increment in haemoglobin is associated with improved QoL, whether induced by growth factor treatment or transfusion therapy.

- Background A significant fraction of women with an impaired factor VIII or IX gene in the X chromosome, carriers of haemophilia, will have clotting factor activities corresponding to those seen in males with non-severe haemophilia, hence, experience an increased bleeding tendency. Data describing the long-term joint outcomes among carriers are limited. We compared the age at onset, frequency of joint-related diagnoses as well as joint surgery and related hospitalizations among carriers of haemophilia with sex- and birthdate-matched controls from the general population. Methods Carriers of haemophilia born 1941-2008 were identified through the haemophilia treatment centres' (HTCs) databases and the National Patient Register of Sweden. For each carrier, we included up to five individuals using the Swedish population register as comparisons. Data for the period 1987-2008 were obtained. Results Among 539 potential carriers identified, 213 had a known factor activity. Carriers with reduced factor activity and those with unknown factor activity had received their first joint-related diagnosis at a significantly earlier age than their comparisons. The same subgroups showed an overall 2.3- and 2.4-fold higher hazard for joint-related diagnoses compared with the general population. In addition, the hazards of joint-related outpatient hospitalization were 3.2-fold (95% CI: 1.2, 9.1) and 2.5-fold (95% CI: 1.6, 3.7). This was not observed for those with normal factor activity. Conclusion Carriers of haemophilia suffer a significant risk for joint comorbidities. This risk seems to correlate to the factor activity. Our findings underline the importance of regular clinical follow-up of carriers at HTCs.
