The psychosocial impact of haemophilia from patients' and caregivers' point of view: The results of an Italian survey.

BACKGROUD: A huge amount of data about psychosocial issues of people with haemophilia (PwH) are available; however, these materials are fragmentary and largely outdated, failing to reflect the impact of current treatment strategies. AIM: Describing the influence of illness on psychosocial aspects of adult PwH (≥18 years) and caregivers of children with haemophilia (CPwH) without inhibitors, in Italy. METHODS: Surveys (for adult PwH, CPwH and haemophilia specialists) were developed by a multidisciplinary working group and conducted from November 2019 to June 2020. RESULTS: A total of 120 PwH without inhibitors and 79 CPwH completed the survey. Adult patients reported a significant impairment in many psychosocial aspects, including working activities, relations with family members and social relations. Caregivers generally reported better scores in all aspects of the survey. Mobility, Pain and Mental health domains of EQ-5D were the most frequently impaired in both patients and caregivers, reducing the perceived quality of life. Genetic counselling was an important issue, 53% of CPwH declaring unawareness of their carrier status, as well as the psychological support offered by the reference center, 67.0% of respondents reporting that no psychological support was provided at the time of diagnosis communication. CONCLUSION: This study provides information about PwH's and CPwH's point of view in the current scenario of continuous innovations in haemophilia treatment and management furthermore, updated insights on psychosocial problems faced by patients and caregivers are reported.

Pattern of use and clinical outcomes with rIX-FP in pediatric/adolescent patients with haemophilia B in Italy: Results from IDEAL real-world study.

OBJECTIVES: To evaluate pattern of use and clinical outcomes in pediatric/adolescent patients enrolled in the IDEAL study. METHODS: This post-hoc analysis of IDEAL retrospective-prospective observational study focused on patients <18 years, 100% on prophylaxis during the entire observation period. RESULTS: Thirteen subjects (median age 10.0 years; 61.5% ≤ 11 years) were analyzed. The infusion frequency changed from 2/week in 84.6% (N = 11) of patients with previous rFIX, to less than 1/weekly in 76.9% (N = 9) with rIX-FP and the annualized number of infusions reduced of 57% (p = .002), from a mean ± SD of 95.1 ± 22.77 to 40.4 ± 6.79, respectively. Annualized mean consumption decreased of about 56% (p = .001), from 3748.4 ± 1155.40 IU/kg with previous rFIX, to 1656.8 ± 456.63 IU/kg of rIX-FP. Mean FIX trough level changed from 3.0% ± 1.98% to 10.92% ± 3.6%. Low mean Annualized Bleeding Rate was maintained across all prophylaxis regimens (0.8 ± 1.69 vs. 0.3 ± 0.89) and zero bleeding patients moved from 69.2% (N = 9) with previous rFIX to 84.6% (N = 11) with rIX-FP (p = .63). Two adverse events, none related to rIX-FP, occurred in two patients. No inhibitors development was reported. CONCLUSIONS: The results in this pediatric/adolescent subgroup support rIX-FP prophylaxis may reduce infusion frequency, while providing high FIX trough levels, stable annualized bleeding rate and a good safety profile.

IDEAL study: A real-world assessment of pattern of use and clinical outcomes with recombinant coagulation factor IX albumin fusion protein (rIX-FP) in patients with haemophilia B in Italy.

INTRODUCTION: Factor IX replacement therapy is used for treatment and prophylaxis of bleeding in haemophilia B. rIX-FP is an extended half-life albumin-fusion protein, which, in clinical studies, has demonstrated prolonged dosing intervals up to 21 days for routine prophylaxis, providing therapeutic benefit. AIMS: To describe dosing frequency and consumption (primary endpoint), efficacy and safety of rIX-FP treatment during routine clinical practice in Italy. METHODS: Patients with moderate/severe haemophilia B on prophylaxis with rIX-FP for ≥6 months, were enrolled in this observational study from October 2017 to February 2019 and followed-up for 2 years. Descriptive analysis included prospective and retrospective data (12 months prior to switching to rIX-FP). RESULTS: Data were collected from 59 male patients (median age 30.1 years) enrolled by 23 Italian centres. Of them, 50 were on prophylaxis during the entire observation period and completed the study. The infusion frequency changed from 2-3 times/week in 86.0% of patients with previous treatment, to less than once a week in 84.0% of patients treated with rIX-FP at the 2nd-year follow-up. The annual number of infusions decreased by about 70%, whereas the mean FIX activity trough level increased from 3.8% to 14.4% (mean > 10% in all the infusion regimens). Median Annualised Bleeding Rate of .0 was achieved across all prophylaxis regimens. Subjects with zero bleedings increased from 66.0% to 78.0% with rIX-FP. CONCLUSION: Treatment with rIX-FP reduced infusion frequency, while providing higher FIX trough levels with substantial benefit in terms of annualised bleeding rate and a good safety profile.

The effect of carriers' reproductive choices and pregnancy history on sporadic severe haemophilia: A 20-year retrospective study through a regional registry.

INTRODUCTION: Haemophilias are X-linked inherited bleeding disorders, due to de novo F8/F9 gene variants in 30-50% of cases. The identification of causative variant in index cases (IC) is crucial for genetic counselling in related women. Over the last 20 years the Emilia-Romagna Regional Haemophilia Registry documented high proportions of sporadic severe haemophilia. AIM: To clarify if carriers' reproductive choices influence the sporadic/familial ratio of severe haemophilia. METHODS: Genetic counselling and genotyping in 221 relatives of severe IC were retrospectively reviewed, retrieving reproductive choices and pregnancy history of childbearing-age carriers from familial and sporadic pedigrees and according to the IC degree of relationship (mothers, daughters, II/other). RESULTS: Carriers' identification rates were lower in sporadic women and in other-degree relatives. Among childbearing age women (n = 140), carriers were 37/48 (77%) and 57/92 (62%) of familial and sporadic relatives, respectively. Forty-five/57 sporadic carriers experienced 67 pregnancies, while 21/37 familial carriers had 39 pregnancies (four voluntary terminations), with a significantly higher number of affected sons in the former (40/67 vs. 12/35, P = .025). Prenatal diagnosis was chosen by 40% and 47% of sporadic and familial aware carriers, respectively. Sporadic mothers often avoided further pregnancies (17/38, 45%) after a firstborn affected child, while familial mothers tended to face pregnancies without prenatal approaches (6/10, 60%). CONCLUSION: In this cohort sporadic offspring account for more than 70% of severe haemophilia cases. This increasing proportion is likely to reflect the influence in reproductive choices of awareness of carriers' status, particularly in sporadic mothers, and of prenatal diagnosis options.

Predictors of inhibitor eradication by primary immune tolerance induction in severe haemophilia A with high responding inhibitors.

BACKGROUND: Immune tolerance induction (ITI) is the only proven strategy to eradicate factor VIII inhibitors in patients with haemophilia A (HA). AIM: To identify patients and treatment options with the highest chance of inhibitor eradication by primary ITI. PATIENTS AND METHODS: In the frame of the Italian ITI Registry, carried out from 1995 to 2015 (last follow-up 2018), 137 primary ITI courses in severe HA patients (90/137 with poor prognosis) were analysed for predictors of outcome (complete/partial response or failure). Sixty-six of them (48%) were prospectively evaluated. RESULTS: ITI was successful in 91/137 patients (66.4%) and 70 (51.1%) achieved complete response within 11 months (median). Historical peak titres ≤200 BU/ml (P = .033), inhibitor titres ≤5 BU/ml at ITI start (P = .001), peak titres ≤100 BU/ml during ITI (P < .001) and missense mutations and small insertions/deletions of FVIII gene (P = .027) predicted complete inhibitor eradication. A score that considers the cumulative number of these variables predicted complete response with positive predictive values up to .81 at ITI start and .91 during ITI, respectively. Patients who had no bleeding (OR, 3.45, 95% CI: 1.4-8.6) nor other adverse events (OR 2.6, 95%CI: 1.3-5.3) during ITI had higher chances of complete response. During the 120-month follow-up (median), 2/70 patients who had achieved complete response relapsed (2.9%). CONCLUSIONS: This Registry, with a centralized review of outcomes, homogeneous data collection (half of which prospective) and long-term follow-up, provides insights for optimizing ITI, with a rationale for further studies in the currently evolving scenario of inhibitor management in HA patients.

Haemophilia management and treatment: An Italian survey on patients', caregivers' and clinicians' point of view.

INTRODUCTION: Haemophilia management and patients' quality of life significantly improved. However, data on current patients', caregivers' and clinicians' satisfaction and limitations of treatments and haemophilia management are limited. AIM: Assessing the management satisfaction and unmet needs from the perspective of Italian patients with haemophilia (PWH) without inhibitors (or caregivers if children) and of specialist physicians. METHODS: Surveys (for patients≥18 years, caregivers of children and haemophilia specialists) were developed by a multidisciplinary working group and conducted from November 2019 to June 2020. RESULTS: Among 275 participants, 120 (43.6%) were PWH without inhibitors, 79 (28.7%) caregivers and 37 (13.4%) clinicians. Patients and caregivers perceived a higher control of the disease compared to clinicians. However, more than 40% of patients and caregivers reported to feel significantly conditioned by the risk of bleeding during their daily life. PWH reported a 6-month mean/median (range) of bleeds 2.3/.0 (0-24) and caregivers 1.3/.0 (0-16) in children. The treatment burden (frequency of administration) was not satisfactory for more than half adults and caregivers of children treated with prophylaxis. A good access to treatment, haemophilia centres and medical service was reported, with issues associated to the multidisciplinary approach and treatment at emergency department. CONCLUSIONS: This large national study provides an updated overview of haemophilia care in Italy from different points of views, highlighting positive aspects and unmet needs. This information can guide future interventions to improve haemophilia management and the assessment of impact of new treatment options.

Risk of bleeding and thrombosis in inherited qualitative fibrinogen disorders.

OBJECTIVES: Inherited dysfibrinogenemia is a rare disorder, for which clinical studies related to the risk of bleeding or thrombosis and the type of causative mutation are scanty. MATERIALS AND METHODS: We analyzed the laboratory, clinical, and genotypic features of 50 patients with inherited dysfibrinogenemia belonging to 19 unrelated families. RESULTS: In all the index cases, fibrinogen activity by Clauss method was below the normal range, while it was observed in 57.9% only by PT-derived method. In three families, hypodysfibrinogenemia was evident, associated with three novel mutations (Ter492Gln in FGB, Cys365Asp, and Leu370Phe in FGG). Three additional novel mutations were also identified (Arg114Lys in FGA, Ile131Thr and Trp234Arg in FGG). Bleeding symptoms assessed by ISTH-BAT scored at least 1 in 30% of patients and, significant bleeding symptoms were mainly present in female patients, especially associated with pregnancy. Two patients with FGB Arg44Cys suffered from venous thromboembolism, and two with FGA Arg35His had ischemic stroke at older age. CONCLUSIONS: This study confirms the heterogeneity of clinical features in inherited dysfibrinogenemia, due to the wide spectrum of the causative mutations. Larger multicenter studies are needed to assess the definitive correlation of some mutations with bleeding or thrombosis.

A Web Site to Improve Management of Patients with Inherited Bleeding Disorders in the Emergency Department: Results at 2 Years.

Treatment of patients with inherited bleeding disorders (PWIBD) in the emergency department (ED) is challenging. In 2010, a project was started involving all eight hemophilia centers (HC) and all 44 EDs of the Region of Emilia-Romagna (Italy) to improve emergency care for PWIBD. The project incorporates guidelines for emergency treatment, education for ED staff, and a dedicated Web site providing extensive information, proposing treatments, and sharing data with patients' electronic clinical records. A Web algorithm, accessible to PWIBD as well as ED and HC staff, suggests the first dose of concentrate for each type and severity of bleed or trauma. Following training courses in each ED, the network was activated. During 2012 and 2013, the site was visited 14,000 times, the EDs accessed the Web site 1,739 times, and used the algorithms 206 times. In two reference EDs, triage-assessment and triage-treatment times were reduced in 2013 and 2012 (27/20 and 110/71.5 minutes, respectively) and medical advice from the HC increased (54 vs. 24% cases). The main advantages of this system are better management of patients in ED (shorter triage-to-treatment times) and improved collaboration between HCs and EDs. The most critical point remaining is staff turnover in EDs, necessitating continual training.

Anti-inhibitor coagulant complex prophylaxis in hemophilia with inhibitors.

BACKGROUND: Patients with severe hemophilia A and factor VIII inhibitors are at increased risk for serious bleeding complications and progression to end-stage joint disease. Effective strategies to prevent bleeding in such patients have not yet been established. METHODS: We enrolled patients with hemophilia A who were older than 2 years of age, had high-titer inhibitors, and used concentrates known as bypassing agents for bleeding in a prospective, randomized, crossover study comparing 6 months of anti-inhibitor coagulant complex (AICC), infused prophylactically at a target dose of 85 U per kilogram of body weight (±15%) on 3 nonconsecutive days per week, with 6 months of on-demand therapy (AICC at a target dose of 85 U per kilogram [±15%] used for bleeding episodes). The two treatment periods were separated by a 3-month washout period, during which patients received on-demand therapy for bleeding. The primary outcome was the number of bleeding episodes during each 6-month treatment period. RESULTS: Thirty-four patients underwent randomization; 26 patients completed both treatment periods and could be evaluated per protocol for the efficacy analysis. As compared with on-demand therapy, prophylaxis was associated with a 62% reduction in all bleeding episodes (P<0.001), a 61% reduction in hemarthroses (P<0.001), and a 72% reduction in target-joint bleeding (≥3 hemarthroses in a single joint during a 6-month treatment period) (P<0.001). Thirty-three randomly assigned patients received at least one infusion of the study drug and were evaluated for safety. One patient had an allergic reaction to the study drug. CONCLUSIONS: AICC prophylaxis at the dosage evaluated significantly and safely decreased the frequency of joint and other bleeding events in patients with severe hemophilia A and factor VIII inhibitors.

Perceived challenges and attitudes to regimen and product selection from Italian haemophilia treaters: the 2013 AICE survey.

Despite great advances in haemophilia care in the last 20 years, a number of questions on haemophilia therapy remain unanswered. These debated issues primarily involve the choice of the product type (plasma-derived vs. recombinant) for patients with different characteristics: specifically, if they were infected by blood-borne virus infections, and if they bear high or low risk of inhibitor development. In addition, the most appropriate treatment regimen in non-inhibitor and inhibitor patients compel physicians operating at the haemophilia treatment centres (HTCs) to take important therapeutic decisions, which are often based on their personal clinical experience rather than on evidence-based recommendations from published literature data. To know the opinion on the most controversial aspects in haemophilia care of Italian expert physicians, who are responsible for common clinical practice and therapeutic decisions, we have conducted a survey among the Directors of HTCs affiliated to the Italian Association of Haemophilia Centres (AICE). A questionnaire, consisting of 19 questions covering the most important topics related to haemophilia treatment, was sent to the Directors of all 52 Italian HTCs. Forty Directors out of 52 (76.9%) responded, accounting for the large majority of HTCs affiliated to the AICE throughout Italy. The results of this survey provide for the first time a picture of the attitudes towards clotting factor concentrate use and product selection of clinicians working at Italian HTCs.

Physical Activity, Bleedings and Quality of Life in Subjects with Haemophilia A without Inhibitors-A Multicenter, Observational Italian Study with a Wearable Device.

Background: This study aimed to gather data on physical activity (PA), bleeding, health-related quality of life, and health status, using a wearable device and an electronic patient-reported outcome (ePRO) app, in individuals with moderate or severe hemophilia A (HA) without inhibitors receiving treatment according to the clinical practice. Methods: This is a 12-month multicenter cohort study conducted in Italy. The primary outcomes included the description of PA by type and intensity, adherence to World Health Organization guidelines, bleeding, and health-related quality of life by EQ-5D questionnaire. PA data were collected continuously through a fitness tracker worn by the patient; all the other variables were collected through ePRO questionnaires. Results: Only 54 of the 103 enrolled subjects (52.4%) used their fitness tracker for the defined valid period; adolescents were the least compliant age group. PA was performed at low rates and intensity. Approximately 52% of the subjects had sedentary behavior. The mean EQ-5D values did not change over time. At least one bleeding was reported in 43.7% of the subjects, mostly with sedentary behavior. The PA in the 2 days preceding the bleeding was comparable to the one observed in the overall observational period. Conclusions: The systematic recording of data through a fitness tracker and ePRO app shows that subjects with HA without inhibitors have lower-than-expected PA and that they still experience issues related to bleeding.

A multicenter, real-world experience with recombinant FXIII for the treatment of patients with FXIII deficiency: from pharmacokinetics to clinical practice. The Italian FXIII Study.

BACKGROUND: Congenital factor XIII (FXIII) deficiency is a rare coagulation disorder characterized by muscular or mucocutaneous bleeding with life-threatening intracranial hemorrhages (ICHs), especially in cases with severe disease. The best treatment is the use of prophylactic plasma-derived or recombinant FXIII (rFXIII). Few data on the use of rFXIII in the real-world scenario are available. The main goal of this study was to assess the efficacy and safety of catridecacog (NovoThirteen®) in a population of patients with FXIII deficiency. Other objectives were to compare the different pharmacokinetic (PK) profiles of each patient and to use them to create a tailored prophylaxis regimen. MATERIALS AND METHODS: We collected and analyzed all pharmacokinetic and clinical data in our registry of the patients with congenital FXIII deficiency treated with rFXIII at eleven Italian hemophilia centers. Data were collected from January 2019 to December 2020. RESULTS: Overall, data on 20 patients with FXIII deficiency were collected, 16 of whom presented with severe disease. Pharmacokinetics was assessed in 18 cases before starting prophylaxis. Prophylaxis was subsequently started in these patients using a wide range of dosages (25.0-80.0 IU/kg; mean 33.8 IU/kg) and infusion intervals (3.0-8.0 weeks). During a mean follow up of 47 months, two minor bleeds and one ICH in a severe patient who had remained under on-demand treatment were reported. DISCUSSION: Efficacy and safety of rFXIII were proven in all patients. The dosage and infusion timing for the treated patients sometimes differed to those reported in the MENTOR pivotal studies, thus underlying the importance of tailored management in a real-world scenario.

Promoting physical activity in people with haemophilia: the MEMO (Movement for persons with haEMOphilia) expert consensus project.

Regular physical activity can increase joint stability and function, reduce the risk of injury, and improve quality of life of people with haemophilia (PwH). However, a recent review of the literature shows that appropriate physical activity and sport are not always promoted enough in the overall management of PwH. A group of Italian experts in haemophilia care undertook a consensus procedure to provide practical guidance on when and how to recommend physical exercise programmes to PwH in clinical practice. Three main topics were identified -haemophilia and its impact on movement, physical activity recommendations for PwH, and choice and management of sports activity in PwH- and ten statements were formulated. A modified Delphi approach was used to reach a consensus. The group also created practical tools proposing different physical activities and frequencies for different age groups, the Movement Pyramids, to be shared and discussed with patients and caregivers. In conclusion, in the opinion of the working group, physical activity can be considered as a low-price intervention that can prevent/reduce the occurrence of chronic diseases and should be further encouraged in PwH to obtain multiple physical and psychological benefits. Future research should include prospective studies focusing on participation in sports, specific risk exposure and clinical outcomes.

Intracranial Haemorrhage in Haemophilia Patients Is Still an Open Issue: The Final Results of the Italian EMO.REC Registry.

Background: Intracranial hemorrhage (ICH) is a highly serious event in patients with haemophilia (PWH) which leads to disability and in some cases to death. ICH occurs among all ages but is particularly frequent in newborns. Aim: The primary aim was to assess the incidence and mortality due to ICH in an Italian population of PWH. Secondary aims were to evaluate the risk factors for ICH, the role of prophylaxis, and the clinical management of patients presenting ICH. Methods: A retrospective-prospective registry was established in the network of the Italian Association of Haemophilia Centers to collect all ICHs in PWH from 2009 to 2019 reporting clinical features, treatments, and outcomes. Results: Forty-six ICHs were collected from 13 Centers. The ICHs occurred in 15 children (10 < 2 years), and in 31 adults, 45.2% of them with mild hemophilia. Overall, 60.9% patients had severe haemophilia (15/15 children). Overall ICH incidence (×1000 person/year) was 0.360 (0.270−0.480 95% CI), higher in children <2 years, 1.995 (1.110−3.442 95% CI). Only 7/46 patients, all with severe haemophilia, had received a prophylactic regimen before the ICH, none with mild. Inhibitors were present in 10.9% of patients. In adult PWHs 17/31 suffered from hypertension; 85.7% of the mild subjects and 29.4% of the moderate/severe ones (p < 0.05). ICH was spontaneous in the 69.6% with lower rate in children (46.7%). Surgery was required in 21/46 patients for cerebral hematoma evacuation. Treatment with coagulation factor concentrates for at least three weeks was needed in 76.7% of cases. ICH was fatal in 30.4% of the cases. Of the survivors, 50.0% became permanently disabled. Only one-third of adult patients received long term prophylaxis after the acute treatment. Conclusion: The results from our Registry confirm the still high incidence of ICH in infants <2 years and in adults, particularly in mild PWHs presenting hypertension and its unfavorable outcomes. The majority of PWHs were treated on-demand before ICH occurred, suggesting the important role of prophylaxis in preventing such life-threatening bleeding.

Emergency management in patients with haemophilia A and inhibitors on prophylaxis with emicizumab: AICE practical guidance in collaboration with SIBioC, SIMEU, SIMEUP, SIPMeL and SISET.

Emicizumab has been approved in several countries for regular prophylaxis in patients with congenital haemophilia A and FVIII inhibitors because it substantially reduces their bleeding risk and improves quality of life. However, although significantly less frequent, some breakthrough bleeds may still occur while on emicizumab, requiring treatment with bypassing or other haemostatic agents. Thrombotic complications have been reported with the associated use of activated prothrombin complex concentrates. In addition, when surgery/invasive procedures are needed while on emicizumab, their management requires multidisciplinary competences and direct supervision by experts in the use of this agent. Given this, and in order to expand the current knowledge on the use of emicizumab and concomitant haemostatic agents, and reduce the risk of complications in this setting, the Italian Association of Haemophilia Centres (AICE) here provides guidance on the management of breakthrough bleeds and surgery in emergency situations in patients with haemophilia A and inhibitors on emicizumab prophylaxis. This paper has been shared with other National Scientific Societies involved in the field.

Difficult encounters with a hemophilic patient: the inner perspective of physicians.

This study aimed at exploring the hematologists' internal representation of a difficult encounter with a hemophilic patient, using a written open format. Narrations were analyzed with Interpretative Phenomenological Analysis. Three main issues were identified, each with sub-issues: (1) Inside the relationship: to tell or not to tell, the balance between a normal life and a deviant medical condition, the guilt; (2) The borders of the professional role: professional values, the "do-it-all" doctor; and (3) The existential confrontation. This study reveals the deep involvement of physicians with their patients, at a professional level and, strongly, at a personal level. The experience of being so deeply involved should be considered in the continuing medical programs for physicians dealing with hemophilia.

Efficacy of Corticosteroids Alone in the Eradication of Factor VIII Inhibitor in an Old Female with Idiopathic Acquired Haemophilia A: Description of a Case.

Acquired haemophilia A (AHA) is a rare and serious disorder mainly affecting elderly patients. It is caused by the production of autoantibodies directed against coagulation factors; patients present with spontaneous bleeding, potentially fatal, in the absence of familial or personal history. Autoimmune disorders, infections, solid and hematologic tumors, and drugs are predisposing factors, but up to 50 percent of cases remain unexplained. The diagnosis of AHA is confirmed by specific laboratory tests; and the therapy is a clinical challenge, due to the fact that older patients are often affected by comorbidities. By passing agents may be used when persistent bleeding or haemodynamic instability is observed; corticosteroids, alone or with immunosuppressive therapy, are necessary to inhibit the production of the autoantibodies. We describe a case in which steroids in monotherapy successfully, safely, and persistently inhibited the production of anti-Factor VIII antibodies, in an old patient admitted after rheumatologic consult.
