Abstract
Purpose A better understanding of the factors that influence engagement is needed to provide a reference for conducting genetic testing in female relatives of patients with hemophilia (PWH). We therefore determined the perceptions and understanding of genetic testing among female relatives of PWH in China. Methods We carried out a qualitative study using in-depth, semi-structured interviews with 11 female relatives of PWH in Shanxi Province, China. The resulting data were analyzed using thematic analyses. Results This study extracted four topics: uncertainty about carrier genetic status; limited understanding of genetic testing; coexistence of positive and negative coping; and multi-aspect demands. Conclusion Healthcare professionals should provide personalized and multidimensional health education and comprehensive decision-making support to female relatives of PWH, to enhance their motivation and willingness to undergo genetic testing. It is also important to actively improve relevant policies, strengthen the genetic testing service system, and promote the popularization of genetic testing in female relatives of PWH.

Abstract
BACKGROUND: Hemophilia A is often viewed as a male disease; females are usually considered asymptomatic hemophilia A carriers. However, hemophilia A carriers may experience mild-to-severe bleeding events. OBJECTIVE: To compare clinical characteristics, health care resource utilization, and costs incurred by hemophilia A carriers compared with a non-hemophilia A carrier female control population in the United States. METHODS: This retrospective observational cohort study used data from IBM MarketScan Commercial Claims and Encounters and Multi-State Medicaid Databases from January 1, 2016, to September 30, 2019. Patients with a hemophilia A carrier diagnosis were matched to a non-hemophilia A carrier female control group in a 1:2 ratio based on sociodemographic characteristics, pregnancy status, and insurance type. Billed annualized bleed rates, health care resource utilization, and annualized costs were evaluated. Generalized linear models compared annualized total costs in the hemophilia A carrier and control groups. RESULTS: After matching, the hemophilia A carrier group included 121 (Commercial) and 55 (Medicaid) patients, matched 1:2 in the control group. Patients in the hemophilia A carrier group (compared with the control group) had numerically higher joint-related health issues (Commercial: 11.6% vs 7.9%; Medicaid: 7.3% vs 4.5%) and lower soft-tissue disorders (Commercial: 13.2% vs 17.4%; Medicaid: 12.7% vs 14.5%). Musculoskeletal pain was higher (33.1% vs 31.0%) and lower (21.8% vs 25.5%) in the Commercial and Medicaid databases, respectively. Billed annualized bleed rates were higher in the hemophilia A carrier group (Commercial: 0.49 vs 0.33; Medicaid: 0.50 vs 0.29). Significantly more patients in the hemophilia A carrier group had minor bleeds (Commercial: 34.7% vs 22.3% [P = 0.001]; Medicaid: 43.6% vs 20.0% [P < 0.001]) and spontaneous bleeds (Commercial: 35.5% vs 21.5%; Medicaid: 47.3% vs 23.6% [P < 0.001 for both]). Outpatient visits represented the majority of health care resource utilization and were higher in the hemophilia A carrier group for all-cause and bleed-related claims; although less frequent, emergency department and inpatient visits followed a similar trend. In the Commercial and Medicaid databases, hemophilia A carriers incurred approximately 2 times higher mean (SD) all-cause health care total costs than patients in the control group (Commercial: $15,345 [21,871] vs $8,358 [11,939] per patient per year [PPPY]; Medicaid: $9,022 [19,461] vs $4,533 [9,532] PPPY). CONCLUSIONS: Hemophilia A carriers experienced more complications and incurred higher costs (resulting from more outpatient, emergency department, and inpatient visits) compared with patients in the control group. These data suggest that hemophilia A carriers have a high disease and economic burden and may benefit from early diagnosis and management to prevent long-term complications.

Abstract
INTRODUCTION Females with haemophilia A (HA [FHAs]) and HA carriers (HACs) have an increased risk of bleeding and complications compared to the general population. AIM To examine the characteristics, billed annualised bleed rates (ABRb ), costs and healthcare resource utilisation for males with HA (MHAs), FHAs and HACs in the United States. METHODS Data were extracted from the IBM® MarketScan® Research Databases (Commercial and Medicaid) for claims during the index period (July 2016 to September 2018) and analysed across MHAs, FHAs and HACs. RESULTS Dual diagnosis females (DDFs; both HA and HAC claims) were grouped as a separate cohort. MHAs were generally younger than females (all cohorts) by up to 19 years (Commercial) and 23 years (Medicaid). ABRb >0 was more frequent in females. Factor VIII claims were higher for MHAs versus female cohorts. Joint-related health issues were reported for 24.4 and 25.6% (Commercial) and 29.3 and 26.6% (Medicaid) of MHAs and FHAs, respectively; lower rates were reported in the other two cohorts. Heavy menstrual bleeding claims occurred for approximately a fifth (Commercial) to a quarter (Medicaid) of female cohorts. All-cause emergency department and inpatient visits in FHAs and DDFs were similar to, or more frequent than, those in MHAs; bleed-related inpatient visits were infrequent. In MHAs (Commercial), mean all-cause total costs ($214,083) were higher than in FHAs ($40,388), HACs ($15,647) and DDFs ($28,320) with similar trends for Medicaid patients. CONCLUSIONS FHAs and HACs may be undermanaged and undertreated. Further research is needed to fully understand these cohorts' bleeding rates, long-term complications and costs.

Abstract
INTRODUCTION Women and girls with haemophilia (WGH) may have spontaneous/traumatic bleeding similar to that in males with haemophilia, and in addition excessive bleeding during menstruation and delivery. AIM To characterize WGH in China and provide guidance for better management. METHODS We retrospectively analysed the characteristics of WGH registered in the Haemophilia Treatment Center Collaborative Network of China (HTCCNC) Registry, including demographics, diagnosis and treatment, bleeding characteristics, obstetrical and gynaecological experiences, and surgical history. RESULTS A total of 61 females had confirmed haemophilia. Diagnosis and treatment were typically delayed, longer in mild haemophilia than in severe and moderate. The most frequently reported bleeding manifestations were haemarthrosis in severe and moderate patients, and cutaneous bleeding in mild patients. Among 45 postmenarcheal WGH, 21 (46.7%) had history of heavy menstrual bleeding, but only three received treatments. Prenatal diagnosis and management of perinatal haemorrhage were inadequate. Of 34 deliveries in 30 women, nine deliveries were complicated by postpartum haemorrhage, and 22 offspring carried mutations causing haemophilia. Forty-four surgical procedures were performed in 29 patients. Those procedures receiving preoperative coagulation factors coverage were significantly less likely to have excessive bleeding than those who did not (P = .003). CONCLUSION This is the first and largest study describing WGH in China. There are currently deficiencies in the identification, diagnosis, and management of these patients. Improving health insurance policies, establishing haemophilia centres, and multidisciplinary teams for bleeding and perinatal or perioperative management will help reduce morbidity and mortality.

Abstract
BACKGROUND People who have or had the potential to menstruate (PPM) with inherited bleeding disorders (BD) face particular challenges receiving appropriate diagnosis and care and participating in research. As part of an initiative to create a National Research Blueprint for future decades of research, the National Hemophilia Foundation (NHF) and American Thrombosis and Hemostasis Network conducted extensive all-stakeholder consultations to identify the priorities of PPM with inherited BDs and those who care for them. RESEARCH DESIGN AND METHODS Working group (WG) 4 of the NHF State of the Science Research Summit distilled community-identified priorities for PPM with inherited BDs into concrete research questions and scored their feasibility, impact, and risk. RESULTS WG4 identified important gaps in the foundational knowledge upon which to base optimal diagnosis and care for PPM with inherited BDs. They defined 44 top-priority research questions concerning lifespan sex biology, pregnancy and the post-partum context, uterine physiology and bleeding, bone and joint health, health care delivery, and patient-reported outcomes and quality-of-life. CONCLUSIONS The needs of PPM will best be advanced with research designed across the spectrum of sex and gender biology, with methodologies and outcome measures tailored to this population, involving them throughout.

Abstract
INTRODUCTION Women with inherited bleeding disorders experience excessive bleeding that may impair their quality of life, making early diagnosis and treatment critical. However, the experiences of these women regarding access to care has been minimally described. The primary objective of this study was to evaluate and describe barriers to care for women with bleeding disorders. This study was a continuation of our previous work describing the lived experiences of these women. METHODS We undertook a qualitative descriptive study. Inclusion criteria for study enrollment were the following: age ≥18 years, English-speaking, and confirmed diagnosis of an inherited bleeding disorder. Women were recruited across Canada by treating health-care providers and members of the Canadian Hemophilia Society. Telephone interviews were conducted using a semi-structured interview style, transcribed verbatim, and analyzed using descriptive thematic analysis. RESULTS A total of 15 participants were interviewed. Median age was 31 years (range 24-70 years). Four primary themes surrounding barriers to care emerged: (1) lack of health-care provider awareness of bleeding disorders, (2) health-care provider dismissal of symptoms, (3) limited access to specialized care and treatment plans, and (4) need for self-education and advocacy. DISCUSSION We found that women with inherited bleeding disorders experience tension with the health-care system, feeling unheard and poorly understood. Based on our findings, we identified key knowledge and care gaps that could be addressed with awareness and educational initiatives: patient education on vaginal blood loss, updated medical curricula, clear referral guidelines, and telehealth initiatives for patients residing far from hemophilia treatment centers.

Abstract
Congenital coagulopathies are a group of hereditary conditions associated with significant hemorrhagic complications. Women with congenital coagulopathies tend to experience higher bleeding rates resulting from physiological processes and pregnancy and delivery. In these women, it is essential to recognize the symptoms and work in a coordinated way between hematologists and gynecologists.

Abstract
Introduction Women or girls with haemophilia (WGH) represent a group of female symptomatic carriers who experience bleeding events more frequently than non‐carriers. Bleeding events include spontaneous/traumatic bleeds and prolonged bleeding related to surgery, menstruation and pregnancy. Challenges for the treatment of WGH include lack of screening, diagnosis and treatment guidelines. Aim Evaluate clinical characteristics, haemostasis management and clinical outcomes regarding menstruation, childbirth, dental procedures, surgeries and other bleeding events in WGH. Methods A retrospective, non‐interventional review of medical records from WGH among three haemophilia treatment centres (HTCs) was conducted in the United States (2012–2018). Patients with ≥2 visits to the HTC and who had undergone intervention for haemostasis management with the outcome documented were included. Descriptive statistics were used. Results Of 47 women and girls included in the chart review (37 with factor VIII deficiency, 10 with factor IX deficiency), median age at diagnosis was 22.6 years. Approximately 79% (n = 37) were diagnosed with mild haemophilia. Events of interest were primarily managed by factor concentrates or antifibrinolytics. Most treatment approaches were successful across clinical scenarios, except for heavy menstrual bleeding being insufficiently controlled in 8 (57%) of the 14 patients who experienced it. Conclusions Bleeding events in WGH, such as excessive and prolonged bleeding during menstruation, demonstrate a unique burden and require specific medical intervention. These results highlight the importance of assessing the need for haemostasis management in WGH and may contribute to future prospective study designs.

Abstract
INTRODUCTION Despite the many symptoms that women with inherited bleeding disorders experience, no study has specifically sought to explore and understand the lived experiences of these women, nor the barriers to care that they may encounter. The primary objective of this study was to describe the lived experiences of women with inherited bleeding disorders. METHODS Inclusion criteria for study enrollment were the following: age ≥18 years, English speaking, and confirmed diagnosis of an inherited bleeding disorder. Women were recruited across Canada through identification by treating health-care providers and study members of the Canadian Hemophilia Society. Telephone interviews were conducted using a semi-structured interview style, transcribed verbatim, and analyzed using descriptive thematic analysis. RESULTS A total of 15 participants were interviewed. Median age was 31 years (24-70 years old). Four primary themes emerged: uncertainties surrounding diagnosis, conceptualization of experience through family bleeding, intensity of bleeding symptoms, and impact of bleeding on identity and daily life. DISCUSSION To our knowledge, this is the first study to thoroughly describe the experiences of adult women living with inherited bleeding disorders. We found that these women experience multiple uncertainties around their diagnosis. They conceptualize their bleeding by examining family histories; experience severe symptoms irrespective of their underlying diagnosis; and create identities around their bleeding symptoms, which influence multiple aspects of their life. Next study steps will involve sharing work specifically focused on treatment plans, barriers to care, and factors affecting care access.

[PMID: 32165215 DOI: 10.1016/j.jpag.2020.03.001] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2019] [Revised: 02/28/2020] [Accepted: 03/02/2020] [Indexed: 11/18/2022]
Abstract
STUDY OBJECTIVE To explore trends over time in the utilization of the Emergency Department (ED) for adolescents with abnormal uterine bleeding (AUB). DESIGN Retrospective cross-sectional study. SETTING Nationwide Emergency Department Sample database (Healthcare Cost and Utilization Project, Agency for Healthcare Research and Quality, Rockville, MD). PARTICIPANTS Subset of adolescents aged 10-19 years from overall cohort of women aged 10-49 years. INTERVENTIONS All ED visits from 2010-2014 for which International Classification of Diseases, ninth revision codes for AUB were listed as the principal diagnosis were compared. Health insurance coverage, demographic factors, hospital characteristics, comorbid anemia, and comorbid bleeding disorders were explored. MAIN OUTCOME MEASURES Number of visits, ED disposition, blood transfusions, and billing for pelvic ultrasound. RESULTS There were an estimated 262,939 ED visits nationally for women aged 10-49 years for AUB in 2014. Of these, 12.7% (33,511/262,939) were from adolescents aged 10-19 years. The number of adolescent visits with an AUB diagnosis declined by 11% from 2010-2014 (37,642 vs 33,511; P = .026), while visits by patients aged 20-49 did not change significantly (215,309 vs 229,428; P = .19). The number of adolescent visits for which Medicaid was the primary payer increased slightly, from 17,283 to 18,785, from 2010 to 2014 (P = .152), while the number using self-pay decreased from 8769 (23.4%) in 2010 to 5146 (15.4%) in 2014 (P < .0001). CONCLUSION ED visits among adolescents with AUB decreased from 2010 to 2014. There was a sharp reduction in the number of visits funded by self-pay and a slight increase in visits funded by Medicaid.

Healthcare provider perspectives on inequities in access to care for patients with inherited bleeding disorders. PLoS One 2020; 15:e0229099. [PMID: 32078655 PMCID: PMC7032703 DOI: 10.1371/journal.pone.0229099] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2019] [Accepted: 01/29/2020] [Indexed: 11/19/2022] Open
Abstract
INTRODUCTION The ways in which social determinants of health affect patients with inherited bleeding disorders remains unclear. The objective of this study was to understand healthcare provider perspectives regarding access to care and diagnostic delay amongst this patient population. METHODS A healthcare provider survey comprising 24 questions was developed, tested, and subsequently disseminated online with recruitment to all members of The Association of Hemophilia Clinic Directors of Canada (N = 73), members of the Canadian Association of Nurses in Hemophilia Care (N = 40) and members of the Canadian Physiotherapists in Hemophilia Care (N = 44). RESULTS There were 70 respondents in total, for a total response rate of 45%. HCPs felt that there were diagnostic delays for patients with mild symptomatology (71%, N = 50), women presenting with abnormal uterine bleeding as their only or primary symptom (59%, N = 41), and patients living in rural Canada (50%, N = 35). Fewer respondents felt that factors such as socioeconomic status (46%, N = 32) or race (21%, N = 15) influenced access to care, particularly as compared to the influence of rural location (77%, N = 54). DISCUSSION We found that healthcare providers identified patients with mild symptomatology, isolated abnormal uterine bleeding, and residence in rural locations as populations at risk for inequitable access to care. These factors warrant further study, and will be investigated further by our group using our nation-wide patient survey and ongoing in-depth qualitative patient interviews.

Abstract
This article reviews the current understanding and management of abnormal uterine bleeding (AUB) in adolescents. It is hoped that this review will provide readers with an approach to the evaluation and treatment of mild to severe uterine bleeding. AUB is a common problem which has significantly adverse effects on an affected adolescent’s quality of life. The most common underlying condition in AUB in adolescence is anovulation. During the evaluation, pregnancy, trauma and sexually transmitted diseases must be ruled out, regardless of history. It should be kept in mind that AUB during this period may be the first sign of underlying bleeding disorders. Although observation is sufficient in the mild form of AUB, at the other end of the spectrum life-threatening bleeding may necessitate the use of high doses of combined oral contraceptives, intravenous estrogen and/or interventional procedures.

Abstract
INTRODUCTION Postpartum hemorrhage (PPH) affects 6% of all deliveries and is the leading cause of maternal death worldwide (19.7%). The incidence of PPH in women with inherited bleeding disorders is substantially greater than in unaffected women; however, estimates of relative risk are highly variable. To date, their experience with postpartum bleeding has not been well studied. OBJECTIVE We set out to explore the experience with, understanding of, and attitudes regarding postpartum bleeding among women with inherited bleeding disorders. METHODS This qualitative study involved focused interviews of women with inherited bleeding disorders about postpartum bleeding. Women followed at a multidisciplinary clinic for women with inherited bleeding disorders who have experienced childbirth within the last 5 years were included in the study. The interview style was semistructured. Interviews continued until the point of saturation of themes. All interviews were transcribed and then analyzed using qualitative descriptive analysis. RESULTS We interviewed 10 women with inherited bleeding disorders. Themes that emerged were normalization of excessive vaginal bleeding, difficulty distinguishing normal from abnormal postpartum bleeding, and empowerment of women by having a clear delivery care plan. CONCLUSION In this study, women with inherited bleeding disorders were desensitized to heavy vaginal blood loss. As a result, excessive postpartum bleeding was not recognized by many of the women we interviewed. Results highlight the importance of a multidisciplinary delivery care plan for these women. Findings revealed key areas for targeted multidisciplinary intervention.

Abstract
Rare coagulation disorders (RCDs) are a group of diseases due to coagulation factors deficiency leading to life-long bleeding diathesis. The diagnosis of RCDs is challenging due to the limited knowledge of these disorders and the large heterogeneity of their bleeding patterns. The clinical symptoms of RCDs are extremely diverse in terms of bleeding type, site, severity, age at onset, and duration. The strength of the association between clotting factor activity level in plasma and clinical symptoms is also variable within each RCD. The clinical evaluation of RCDs starts with a detailed collection of clinical history and has been facilitated by bleeding assessment tools, however their effectiveness in diagnosing RCDs requires further investigation. The following laboratory diagnosis of RCDs involves coagulation screening tests, including activated partial thromboplastin time, prothrombin time, and thrombin time. After ruling out the presence of an inhibitor by mixing studies, in case of abnormal results, the specific deficiency is identified by performing one-stage clotting assays using the specific factor-depleted plasmas as substrate. In fibrinogen and FXIII deficiencies coagulation screening tests are not informative, therefore additional tests are needed. Global assays have been developed and are thought to aid in patient management, however, they are not well standardized yet. In addition to outlining the principles of clinical and laboratory diagnosis, this review explores molecular basis of RCDs and laboratory techniques for genetic analysis, and discusses the importance and effectiveness of quality control programs to ensure standardized laboratory results.

Abstract
STUDY OBJECTIVE Heavy menstrual bleeding (HMB) occurs in up to 40% of adolescent girls, significantly affecting their daily activities. Identifying alternative treatment strategies for HMB is particularly important for adolescents who prefer not to take hormonal contraception. Our objective was to determine whether use of tranexamic acid (TA) would increase health-related quality of life and decrease menstrual blood loss (MBL) in adolescents with HMB. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: In an open-label, multi-institutional, single-arm, efficacy study, patients 18 years of age or younger with HMB were treated with oral TA 1300 mg 3 times daily during the first 5 days of menses and monitored over the course of 4 menstrual cycles (1 baseline; 3 treatment cycles). Assessment of MBL was performed using the Menorrhagia Impact Questionnaire (MIQ) and the Pictorial Blood Assessment Chart. The MIQ includes Likert scale items, validated to assess the influence of HMB on quality of life. In previous studies, a 1-point decrease or more in score correlated with clinically significant improvement. RESULTS Thirty-two patients enrolled in the study, and 25 had sufficient follow-up data to be deemed evaluable. The mean age of the participants was 14.7 years (range, 11-18 years). There was an overall improvement in all items of the MIQ, with a greater than 1-point improvement in the MIQ perceived blood loss scale. When using TA, mean Pictorial Blood Assessment Chart score improved by 100 points. There were no medication-related serious adverse events. CONCLUSION Use of TA in female adolescents with HMB is well tolerated and leads to clinically meaningful reduction in MBL.

Abstract
INTRODUCTION Historically, issues faced by women with bleeding disorders (WBD) have been underestimated. While advances in genetic testing have resulted in improvements, significant challenges remain in the initial recognition of abnormal bleeding and referral of WBD. METHODS The European Haemophilia Consortium (EHC) developed a questionnaire for WBD to provide insights into the barriers and challenges faced by WBD in Europe. RESULTS In total, 709 WBD responded to the survey from 32 countries, predominantly from western European countries (94%). A delay in ascertaining the diagnosis of a congenital bleeding disorders (CBD) remains, with a median age at diagnosis of 16 years. The presence of family history is strongly associated with a lower median age at diagnosis of 6 years. WBD reported significant disease impact on their day-to-day life, most evident for the rarer CBD. The bleeding symptom of biggest impact on daily life is heavy menstrual bleeding (HMB), reported by 55% of women. Importantly, 25% of WBD reports that their condition severely impacted their decision to have or has prevented them from having children. Respondents registered with Haemophilia Treatment Centres (HTC) are 2.2 times more likely to receive treatment compared to WBD in other hospital services. CONCLUSION Improved education for both patients and healthcare providers is essential to improve time to diagnosis, access to treatment and psychosocial supports for WBD in Europe.

Abstract
The molecular causes of many inherited platelet disorders are being unraveled. Next-generation sequencing facilitates diagnosis in 30% to 50% of patients. However, interpretation of genetic variants is challenging and requires careful evaluation in the context of a patient's phenotype. Before detailed testing is initiated, the treating physician and patient should establish an understanding of why testing is being performed and discuss potential consequences, especially before testing for variants in genes associated with an increased risk for hematologic malignancies.

Abstract
Rare bleeding disorders (RBDs) comprise inherited deficiencies of factors I (fibrinogen), II (prothrombin), V, VII, X, XI, and XIII as well as combined factor V + VIII and vitamin K-dependent factors. They represent 3-5% of all congenital bleeding disorders and are usually transmitted as autosomal recessive traits. These disorders often manifest during childhood and have varied clinical presentations from mucocutaneous bleeding to life-threatening symptoms such as central nervous system and gastrointestinal bleeding. Bleeding manifestations generally vary within the same RBD and may also vary from 1 RBD to the other. Laboratory diagnosis is based on coagulation screening tests and specific factor assays, with molecular techniques providing diagnostic accuracy and enabling prenatal counseling. The approach to treatment of bleeding episodes and invasive procedures needs to be individualized and depends on the severity, frequency and procedure-related risk of bleeding. The first line of treatment of RBDs is replacement of the deficient factor, using specific plasma-derived or recombinant products and using fresh frozen plasma or cryoprecipitate when specific products are not available or in resource-limited countries. Prophylaxis may be considered in individuals with recurrent serious bleeding and especially after life-threatening bleeding episodes. Novel no-replacement strategies promoting hemostasis by through different mechanisms need to be studied in RBDs as alternative therapeutic options.

Abstract
Abnormal uterine bleeding is common in adolescents and is thought to affect 9% to 14% of women in their reproductive years. Certain unique aspects of underlying inherited or acquired blood disorders exacerbate the "expected" hormonal imbalance at this age, thereby increasing the morbidity of the underlying problem. A multifactorial etiology demands a collaborative approach between hematologists and gynecologists or adolescent medicine physicians to effectively manage abnormal uterine bleeding in young women with blood disorders.

Abstract
PURPOSE OF REVIEW Heavy menstrual bleeding (HMB) is a common condition in women of reproductive age; however, adolescents with this issue present unique challenges in both diagnosis and management. Much of the research into this topic focuses on the adult population, with variable applicability to adolescents. There are currently no standard guidelines for the work up and treatment of adolescents with HMB. RECENT FINDINGS Current research into this topic has explored the utilization of standardized protocols in the evaluation of HMB in adolescents, the efficacy of various hormonal, nonhormonal, and surgical treatment modalities, and the benefits of a multidisciplinary approach. Recent literature has focused on adolescents found to have an underlying bleeding disorder, recommending more comprehensive bleeding disorder work up to identify these patients in a timely manner and initiate effective treatment plans. SUMMARY Providers in the primary care setting should be aware of the definitions for normal menses, and be able to recognize abnormal bleeding and HMB. Early recognition of HMB in adolescents can then lead to appropriate diagnosis of underlying disorders, and current research has proposed standard protocols to assist with the evaluation, ultimately leading to effective long-term management into adulthood.VIDEO ABSTRACT.

Abstract
STUDY OBJECTIVE To assess the clinical severity and initial treatment of iron deficiency anemia (IDA) in female adolescents with heavy menstrual bleeding (HMB) in our center. DESIGN Retrospective cohort study of electronic medical records via search of administrative records using International Classification of Diseases Ninth Revision codes for IDA or unspecified anemia and disorders of menstruation. SETTING Children's Medical Center in Dallas, Texas. PARTICIPANTS One hundred seven patients with HMB and concomitant IDA (median age, 14.4 years) who presented to the outpatient, emergency department, and/or inpatient settings. RESULTS The median initial hemoglobin concentration for all patients (n = 107) was 7.4 g/dL, and most (74%, n = 79) presented to the emergency department or via inpatient transfer. Symptomatic IDA was treated with blood transfusion in 46 (43%, n = 46). Ferrous sulfate was the most commonly prescribed oral iron therapy. Seven patients received intravenous iron therapy either initially or after oral iron treatment failure. Combined oral contraceptives were commonly prescribed for abnormal uterine bleeding, yet 10% of patients (n = 11) received no hormonal therapy during their initial management. Evaluation for underlying bleeding disorders was inconsistent. CONCLUSION Severe anemia because of IDA and HMB resulting in urgent medical care, including hospitalization and blood transfusion, is a common but underemphasized problem in adolescent girls. In addition to prevention and early diagnosis, meaningful efforts to improve initial management of adolescents with severe HMB and IDA are necessary.

Abstract
PURPOSE OF REVIEW The present article addresses recent research related to three key facets of adolescent preventive care and health maintenance: long-acting reversible contraception, human papillomavirus vaccination, and heavy menstrual bleeding. RECENT FINDINGS Recent studies suggest that long-acting reversible contraception use results in significantly lower rates of unintended pregnancies, and is well tolerated by nulliparous adolescent females. Additionally, a strong recommendation from a pediatric primary care provider is extremely effective in ensuring human papillomavirus vaccination prior to sexual debut. Finally, heavy menstrual bleeding is often under-recognized in adolescents, and evaluation and treatment of these patients are variable. SUMMARY Based on the recent literature findings, the pediatric primary care provider should be encouraged to, first, recommend long-acting reversible contraception for prevention of unintended pregnancy in adolescent patients; second, strongly endorse vaccination to protect against human papillomavirus in all patients prior to sexual debut; and, third, screen adolescent females for signs and symptoms of heavy menstrual bleeding.

Molecular genetic analysis of the F11 gene in 14 Turkish patients with factor XI deficiency: identification of novel and recurrent mutations and their inheritance within families. BLOOD TRANSFUSION = TRASFUSIONE DEL SANGUE 2016; 16:105-113. [PMID: 27723456 DOI: 10.2450/2016.0098-16] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Subscribe] [Scholar Register] [Received: 04/15/2016] [Accepted: 06/07/2016] [Indexed: 11/21/2022]
Abstract
BACKGROUND Factor XI (FXI) deficiency is an autosomal bleeding disease associated with genetic defects in the F11 gene which cause decreased FXI levels or impaired FXI function. An increasing number of mutations has been reported in the FXI mutation database, most of which affect the serine protease domain of the protein. FXI is a heterogeneous disorder associated with a variable bleeding tendency and a variety of causative F11 gene mutations. The molecular basis of FXI deficiency in 14 patients from ten unrelated families in Turkey was analysed to establish genotype-phenotype correlations and inheritance of the mutations in the patients' families. MATERIAL AND METHODS Fourteen index cases with a diagnosis of FXI deficiency and family members of these patients were enrolled into the study. The patients' F11 genes were amplified by polymerase chain reaction and subjected to direct DNA sequencing analysis. The findings were analysed statistically using bivariate correlations, Pearson's correlation coefficient and the nonparametric Mann-Whitney test. RESULTS Direct DNA sequencing analysis of the F11 genes revealed that all of the 14 patients had a F11 gene mutation. Eight different mutations were identified in the apple 1, apple 2 or serine protease domains, except one which was a splice site mutation. Six of the mutations were recurrent. Two of the mutations were novel missense mutations, p.Val522Gly and p.Cys581Arg, within the catalytic domain. The p.Trp519Stop mutation was observed in two families whereas all the other mutations were specific to a single family. DISCUSSION Identification of mutations confirmed the genetic heterogeneity of FXI deficiency. Most of the patients with mutations did not have any bleeding complications, whereas some had severe bleeding symptoms. Genetic screening for F11 gene mutations is important to decrease the mortality and morbidity rate associated with FXI deficiency, which can be life-threatening if bleeding occurs in tissues with high fibrinolytic activity.

Challenges of diagnosing and managing the adolescent with heavy menstrual bleeding. Thromb Res 2016; 143:91-100. [PMID: 27208978 DOI: 10.1016/j.thromres.2016.05.001] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2016] [Revised: 04/26/2016] [Accepted: 05/01/2016] [Indexed: 11/20/2022]
Abstract
Unpredictable, prolonged or heavy menstrual bleeding (HMB) may be expected for many adolescents soon after menarche. A decade of clinical experience and research has now established firmly that bleeding disorders (BD) are common in adolescents with HMB. Despite these advances, many questions remain, and several aspects of the diagnosis and management of BDs in adolescents are not supported by rigorous clinical trials. In this overview, four major areas will be discussed. First, we will discuss the frequency of BDs in young women with HMB. Up to 20% of older females with HMB are thought to have an underlying BD. Estimates from retrospective studies in adolescents suggest a prevalence that varies anywhere from 10 to 62%. Prospective studies with uniform hemostatic evaluation are needed to answer this question definitively. Second, we will review existing tools that help screen and diagnose adolescents with HMB with an underlying BD. Although identification of an underlying BD in older women with HMB is relatively straight forward, uncertainties remain for adolescents. Heavy menstrual bleeding in this age group may have different pathophysiological underpinnings than those in older women and may often be disregarded as anovulatory. There is an urgent need to develop novel tools, and evaluate existing diagnostic strategies in adolescents. Third, we will discuss the optimal medical management of HMB in young adolescents. As direct evidence is largely lacking, these areas are also subject to extrapolation from older women. Lastly, an important area- prediction, and management of future bleeding in those adolescents who are diagnosed with a mild BD-will be discussed. Throughout, areas of controversy and opportunities for further research are highlighted.
