Inherited bleeding disorders in Indian women with menorrhagia

Reproductive health and hemostatic issues in women and girls with congenital factor VII deficiency: A systematic review

BACKGROUND

Congenital factor VII (FVII) deficiency is an inherited bleeding disorder, with heterogenous bleeding symptoms. Women with FVII deficiency face hemostatic challenges during menstruation, ovulation, and childbirth. This systematic review evaluated prevalence and management of bleeding symptoms associated with gynecological and obstetric issues in women with FVII deficiency.

METHODS

Databases (BIOSIS Previews, Current Contents Search, Embase, and MEDLINE) were searched for studies reporting FVII deficiency and gynecological or obstetric issues in women. Articles were screened using Joanna Briggs Institute checklists and relevant data extracted.

RESULTS

One hundred fourteen women were identified from 62 publications. Forty-six women had severe deficiency (FVII:C < 5% or <5 IU/dl). Heavy menstrual bleeding (HMB) was the most common bleeding symptom (n = 94; 82%); hospitalization and urgent medical/surgical interventions for acute HMB episodes were required in 16 women (14%). Seven women reported ovarian bleeding (6%); other bleeding symptoms varied. Patient management was inconsistent and included hemostatic and hormonal treatments. Only four women (7%) reporting vaginal bleeding during pregnancy. Postpartum hemorrhage (PPH) occurred following 12/45 deliveries (27%; 5 [42%] requiring blood transfusion) and was not necessarily prevented by prophylaxis (8 women).

CONCLUSION

Women with congenital FVII deficiency have an increased risk of HMB, ovarian bleeding, and PPH, impacting quality of life. Recognition of a bleeding disorder as the cause is often delayed. Management of bleeding complications is heterogeneous due to lack of treatment guidelines. Harmonizing severity classification of FVII deficiency may help standardize treatment strategies and development of specific guidelines for these women.

EVALUATION OF HEMOSTASIS PARAMETERS IN ADOLESCENT GIRLS PRESENTING WITH MENOMETRORRHAGIA AND COMPARISON WITH HEALTHY ADOLESCENTS

Objective: This study aims to investigate the presence of acquired and hereditary coagulation in adolescent girls presenting with increased menstrual bleeding. Method: The study consisted of 63 adolescent female patients (15.4±1.5 years) who applied to the pediatric clinic of our hospital due to increased menstrual bleeding, did not have any acute or chronic disease, did not use any medication in the last 14 days, and were of the same age and gender as the study group. 74 healthy adolescents were taken as the healthy control group (15.5±1.5 years). Platelet count, all basal and advanced coagulation tests, platelet aggregation, and secretion tests were studied for each case included in the study. Results: When basal and advanced coagulation tests, platelet aggregation, and secretion tests were examined, no significant difference was found between the study and the healthy control group. On the other hand, in our study group with heavy menstrual bleeding, 4 (6.3%) patients were found to have impaired hemostasis (2 patients with type 1 von Willebrand disease, one patient with immune thrombocytopenic purpura, and one patient with mild factor VIII deficiency). Conclusion: Various hemostasis disorders, especially von Willebrand disease, could be detected in the group with heavy menstrual bleeding.

Screening hemostatic defects in Saudi University students with unexplained menorrhagia: a diagnosis, which could be missed

Bleeding disorders are a common cause of unexplained menorrhagia in adolescents. However, there is lack of information provided on Arab girls. To estimate the prevalence of coagulation factor deficiencies and platelet dysfunction among Saudi university students with unexplained menorrhagia. In this cross sectional study, 463 adolescent girls surveyed for having heavy menses for further evaluation of underlying bleeding tendencies using screening standardized questionnaire. Only 109 girls out of the total 463 girls reported menorrhagia and were included in the evaluation. All girls with menorrhagia were evaluated by Pictorial blood assessment chart (PBAC) for precise evaluation of menstrual blood loss (PBAC score >100), had underwent pelvic ultrasonography and screening of hemostatic abnormalities (complete blood count, PFA-100, PT, aPTT, vWF:RCo, vWF:Ag, coagulation factors assay). On the basis of the score of PBAC more than 100, 25.6% (28/109) of adolescent women (age ranged: 17-25 years old) had confirmed menorrhagia. In 30.8% of them, an ultimate diagnosis of bleeding tendency or hemostatic abnormality was detected [five cases of probable von Willebrand disease (vWD) or low level of vWF:Ag and/or vWF:RCo, two cases of probable platelet dysfunction, and one case of factorV (FV) deficiency]. Anemia was found in 39.28% (11/28) of them; however, only 4 (36%) had received iron supplements. Our study demonstrated that hemostatic defects are not uncommon in Saudi adolescent women presenting with menorrhagia but mostly unrecognized and untreated. It is probably advisable to screen women with menorrhagia for these defects.

Spectrum of hemostatic disorders in Indian females presenting with bleeding manifestations

INTRODUCTION

Hemostatic disorders are often missed in women with bleeding particularly menorrhagia. Preexisting hemostatic disorders are now known as common risk factor for postpartum hemorrhage and prolonged bleeding in puerperium. Females with bleeding complaints constitute an important population referred to hematology clinic. Hence, we aim to evaluate the type and frequency of hemostatic disorders among females presenting with bleeding in a tertiary care hospital and a basic hemostatic laboratory.

METHODS

Three-year data were retrospectively analyzed for 200 females with various bleeding complaints. Due to resource constraints, a hemostatic workup was done with prothrombin time, activated partial thromboplastin time, thrombin time, fibrinogen assay, clot solubility test, mixing studies, specific factor assays, platelet function test, and von Willebrand factor antigen level.

RESULTS

A total of 200 females were investigated to identify the cause of their bleeding. Thirty-five of 200 (17.5%) females were found with an underlying bleeding disorder. Of these 35 females, 65.7% presented with bleeding from more than 1 site. Most common bleeding manifestation was spontaneous bruising in 18 of 35 (51.4%) patients followed by petechiae (48.6%). Inherited bleeding disorders were noted in majority. The most common inherited bleeding disorder identified was von Willebrand disease (VWD) in 34.3% females. Second most common disorder was Glanzmann's thrombasthenia accounting for 22.8%. Rare coagulation factor deficiency, such as factors VII, X, and XIII deficiencies, was noted. Three cases revealed acquired causes of coagulation defects.

CONCLUSION

Underlying hemostatic defects should be searched for in women with unexplained bleeding complaints. This will not only help in diagnosis but also in proper management for future hemostatic challenges.

Non-surgical interventions for treating heavy menstrual bleeding (menorrhagia) in women with bleeding disorders

BACKGROUND

Heavy menstrual bleeding without an organic lesion is mainly due to an imbalance of the various hormones which have a regulatory effect on the menstrual cycle. Another cause of heavy menstrual bleeding with no pelvic pathology, is the presence of an acquired or inherited bleeding disorder. The haemostatic system has a central role in controlling the amount and the duration of menstrual bleeding, thus abnormally prolonged or profuse bleeding does occur in most women affected by bleeding disorders. Whereas irregular, pre-menarchal or post-menopausal uterine bleeding is unusual in inherited or acquired haemorrhagic disorders, severe acute bleeding and heavy menstrual bleeding at menarche and chronic heavy menstrual bleeding during the entire reproductive life are common. This is an update of a previously published Cochrane Review.

OBJECTIVES

To determine the efficacy and safety of non-surgical interventions versus each other, placebo or no treatment for reducing menstrual blood loss in women with bleeding disorders.

SEARCH METHODS

We searched the Cochrane Cystic Fibrosis Haemoglobinopathies Trials Register (25 August 2016), Embase (May 2013), LILACS (February 2013) and the WHO International Clinical Trial registry (February 2013).

SELECTION CRITERIA

Randomised controlled studies of non-surgical interventions for treating heavy menstrual bleeding (menorrhagia) in women of reproductive age suffering from a congenital or acquired bleeding disorder.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed studies for inclusion, extracted data and assessed the risk of bias.

MAIN RESULTS

Three cross-over studies, with 175 women were included in the review. All three studies had an unclear risk of bias with regards to trial design and overall, the quality of evidence generated was judged to be poor.Two of the studies (n = 59) compared desmopressin (1-deamino-8-D-arginine vasopressin) with placebo. Menstrual blood loss was the primary outcome for both of these studies. Neither study found clear evidence of a difference between groups. The first of these reported a mean difference in menstrual blood loss in the desmopressin versus placebo group of 21.20 mL (95% confidence interval -19.00 to 61.50)The second study reported that even though there was an improvement of pictorial bleeding assessment chart scores with desmopressin and placebo when compared to pretreatment assessment, there was no clear evidence of difference in these scores when the two were compared to each other (results presented graphically, P = 0.51). The data from these studies could not be combined.The third study (n = 116) compared desmopressin with tranexamic acid (n = 116). This study found a decrease in pictorial bleeding assessment chart scores after both treatments as compared to baseline. The decrease in these scores was greater for tranexamic acid than for desmopressin, with a mean difference of 41.6 mL (95% confidence interval 19.6 to 63) (P < 0.0002).In relation to adverse events, across two studies, there was no clear evidence of a difference when placebo was compared to desmopressin, risk ratio 1.17 (95% confidence interval 0.41 to 3.34) . The same was also true when desmopressin was compared to tranexamic acid, risk ratio 1.17 (95% confidence interval 0.41 to 3.34).Only the study that compared desmopressin to tranexamic acid assessed quality of life. However, we are unable to present any data from this study, since no differences in this outcome between the two intervention groups were reported.

AUTHORS' CONCLUSIONS

Evidence from randomised controlled studies on the effect of desmopressin when compared to placebo in reducing menstrual blood loss is very limited and inconclusive. Two studies, each with a very limited number of participants, have shown uncertain effects in menstrual blood loss and adverse effects. A non-randomised comparison in one of the studies points to the value of combining desmopressin and tranexamic acid, which needs to be tested in a formal randomised controlled study comparison.When tranexamic acid was compared to desmopressin, a single study showed a reduction in menstrual blood loss with tranexamic acid use compared to desmopressin.There is a need to evaluate non-surgical methods for treating of menorrhagia in women with bleeding disorders through randomised controlled studies. Such methods would be more acceptable than surgery for women wishing to retain their fertility. Given that women may need to use these treatments throughout their entire reproductive life, long-term side-effects should be evaluated.

Gynecological Problems of Adolescent Girls Attending Outpatient Department at Tertiary Care Center with Evaluation of Cases of Puberty Menorrhagia Requiring Hospitalization

ABSTRACT

Adolescence is a period of enormous physical and psychological change for young girls. Many adolescents with menstrual disturbances never present to their family doctor or gynecologist. Embarrassment about discussing menstruation, fear of disease, and ignorance about services available may lead to delayed presentation or consultation with doctor.

AIMS AND OBJECTIVE

To evaluate the different gynecological problems in adolescent girls attending outpatient department.To evaluate the prevalence of severe anemia requiring indoor admission in adolescent girls with puberty menorrhagia.To assess the etiologies of puberty menorrhagia.

RESULT

There were a total of 655 adolescent girls attending the gynecology OPD during the study period. Menstrual complaints (84.88 %) were the commonest indication for OPD consultation among adolescent girls. 17 girls required hospitalization; all of them needed blood transfusion due to significant severe anemia resulting from puberty menorrhagia. 14 (82.35 %) had anovulatory DUB, while 2 (11.76 %) had coagulation disorders, and one (5.88 %) had hypothyroidism.

CONCLUSION

Adolescent girls with menorrhagia need to be evaluated thoroughly earlier rather than later so that effective management can be started and severe anemia with its consequences can be avoided. Adolescent health education and group discussion is needed to create awareness regarding adolscent gynecological problems; it should be conducted regularly in schools and colleges.

Spectrum of Inherited Bleeding Disorders in Indians

The incidence of hereditary hemorrhagic disorders may vary according to the country and ethnic origin. Von Willebrand disease has emerged as the most common hereditary hemorrhagic disease in the industrialized world. In this series of 966 patients diagnosed to have inherited bleeding disorders, hemophilia A was the most common and was seen in 410 (42.4%) of the patients followed by platelet function defects seen in 380 (39.4%) of the patients. It is thus concluded that, similar to the white population, hemophilia A remains the most common bleeding disorder in the Indian population, although this is closely followed by platelet function defects in India, which are quite rare in whites. Von Willebrand disease is relatively rare in the Indian population.

Screening of von Willebrand disease in Iranian women with menorrhagia

Background:

Menorrhagia is a common health problem in women, particularly those with bleeding disorders. Little is known about the course of menorrhagia or other bleeding symptoms in women with the most common congenital bleeding disorder, von Willebrand disease (vWD).

Objectives:

The aim of this study was to estimate the prevalence of vWD in women with diagnosed menorrhagia.

Materials and Methods:

In this cross-sectional study, a total of 460 consecutive patients, presenting menorrhagia, were analyzed. The initial screening and confirmation tests for the diagnosis of vWD included determination of prothrombin time (PT), partial thromboplastin time (PTT), bleeding time (BT), fibrinogen, factor VIII, vWF antigen, and vWF activity. A questionnaire was filled for every patient. The data were then analyzed using the SPSS software.

Results:

Mean age of our patients was 32.5 ± 10.6 years. The level of von Willebrand factor in 22.5% and von Willebrand activity in 19.6% of patients was abnormal. The prevalence of vWD among patients with menorrhagia was 24%.

Conclusions:

The high prevalence of vWD among our patients was the same as other previous reports, suggesting low awareness about this disease and under diagnosis of mild cases.

Clinical and laboratory characteristics of adolescents with platelet function disorders and heavy menstrual bleeding

BACKGROUND

Platelet function disorders (PFDs) have emerged as an important etiology of heavy menstrual bleeding (HMB) in adolescents. However, neither clinical nor laboratory data have been methodically analyzed in this population subset. The objective of this study was to evaluate these parameters in order to distinguish characteristics of the disorder that in turn will lead to earlier diagnosis and therapy initiation.

METHODS

Retrospective review of medical records from postmenarcheal adolescents with documented PFDs referred to a hemophilia treatment center and university faculty practices for bleeding diatheses with their clinical and laboratory data evaluated.

RESULTS

Of 63 teens with documented PFDs, HMB was the most common clinical manifestation of PFD (43; 68.3%). Of these, 37 (86%) were diagnosed with PFD either at or after menarche with the diagnosis based on HMB symptoms alone. Only 6 (14%) were diagnosed with a PFD prior to menarche, based on associated bleeding, i.e., epistaxis, ecchymosis, and all developed HMB after menstruation onset. Interestingly, 20 girls were diagnosed with a PFD prior to menarche and of these, only 6 (30%) went on to develop HMB after pubertal transition, while the majority (14; 70%) did not. The average age-at-PFD diagnosis was 14.5yrs, significantly differing from the 10.9yrs average age-at-PFD diagnosis in their counterparts that, after menarche, did not develop HMB (P<.01) Blood type O occurred significantly more frequently (76%) than national norms (P <.037). Incidence of δ-Storage Pool deficiency (δ-SPD) was significantly higher (74%) than their non-HMB cohorts (45%) (P <.007). Coagulation and von Willebrand factor studies were all normal. Abnormal closure times and aggregation studies were observed in 42% and 60%, respectively, of tested girls. In 25.6% for whom standard platelet studies were normal, electron microscopy detected reduced platelet δ-granules numbers (δ-SPD).

CONCLUSIONS

Adolescents with PFDs and HMB appear to be clinically distinct from their non-HMB counterparts. This group of girls is characterized by HMB the major bleeding symptom, significantly high incidences of blood group O and the δ-SPD with a PFD diagnosed well after menarche. High false negative standard platelet function study results indicate additional diagnostic strategies, particularly for δ-SPD, should be considered.

Prothrombin Complex Concentrate Such as Therapy and Prophylaxis in Factor X-Deficient Patient (Friuli Variant)

Background: Factor X (FX) deficiency is a serious, rare bleeding disorder, with 1 in 500 000 affected people. Hemorrhages, hematuria, epistaxis, and other bleeding complications are frequent. Case Report: Now, we report a case of a well-known 77-year-old FX-deficient patient (Friuli variant, level <1%, mutation Pro343→Ser, exon VIII) with hypertension, chronic obstructive pulmonary disease (COPD), and chronic gastritis, admitted many times to hospital due to surgical complications after aortic abdominal aneurysm (AAA) repair. Use of prothrombin complex concentrate (PCC) such as hemostatic therapy during surgeries and prophylaxis after discharge is shown in this article. Three consecutive surgeries were considered. First, endoleak postendoprosthesis; second, AAA breakage; and third, planned surgery, a new endovascular prosthesis positioning and femur-femoral bypass. No adverse events due to PCC were found by local physicians. Discussion: We discuss the methods commonly used in the treatment and prophylaxis of patients with FX deficiency to reduce hemorrhagic risk and to improve their quality of life. Conclusion: Waiting for specific therapeutic options for FX deficiency, currently, the best treatment is represented by PCC. Its correct use permits an improvement in life quality and a reduction in bleeding frequency in FX-deficient patients.

[Appropriate laboratory investigation in women with menorrhagia]

Inherited bleeding disorders are potentially causes of menorrhagia and must be investigated if no specific cause is identified. The reported prevalence of inherited bleeding disorders is high in women with menorrhagia compared to the general population. The most frequent disorders reported are von Willebrand's disease and Factor XI deficiency. Menorrhagia is, also, a frequent finding in women with congenital bleeding disorders. Morever, menorrhagia represents the major cause of iron-deficiency anemia among women of reproductive age. Primary evaluation for an underlying disorder of hemostasis in a woman wih menorrhagia is a focused history for familiy and personal history of bleeding symptoms and a complete blood cell count. This will rule out thrombocytopenic bleeding and also assesses for the degree, if any, of anemia. Those women with a positive screen and normal platelet count should be evaluated with laboratory investigation including prothrombin time, activated partial thromboplastin time, factor VIII, VWF ristocetin cofactor and antigen. If initial hemostasis testing above is normal, then further hemostasis testing can be considered, especially in terms of platelet aggregation, in a multidisciplinary clinic.

Development of a screening tool for identifying women with menorrhagia for hemostatic evaluation

OBJECTIVE

A study was conducted to develop a short, easy to administer screening tool useful for stratifying women with unexplained menorrhagia for hemostatic testing for underlying bleeding disorders.

STUDY DESIGN

One hundred forty-six women with a physician diagnosis of menorrhagia underwent comprehensive hemostatic testing for the diagnosis of bleeding disorders, including von Willebrand disease, platelet dysfunction, and coagulation factor deficiencies. A 12 page questionnaire of bleeding symptoms was administered. Bleeding symptoms with high predictive values for laboratory hemostatic abnormalities were combined and used as single variables to calculate sensitivity, specificity, and positive and negative predictive values in order to develop a short screening tool to identify females for testing and evaluation.

RESULTS

A combination of 8 questions in 4 categories resulted in a sensitivity of 82% (95%CI 75-90) for bleeding disorders. Adding a pictorial blood assessment chart score > 100 increased the sensitivity of the screening tool to 95% (95%CI 91-99).

CONCLUSION

These results demonstrate the feasibility of a simple questionnaire based screening tool to identify females for testing and evaluation for bleeding disorders.

Screening women with menorrhagia for underlying bleeding disorders: the utility of the platelet function analyser and bleeding time

Menorrhagia is a very common clinical problem among women of reproductive age and recent studies have suggested that underlying bleeding disorders, particularly von Willebrand's deficiency and platelet function defects, are prevalent in women presenting with menorrhagia. The objective of this study was to determine the utility of the platelet function analyser (PFA-100) and bleeding time (BT) as initial screening tests for underlying bleeding disorders in women with menorrhagia. In this study, 81 women with a physician diagnosis of menorrhagia underwent PFA-100 testing, BT and comprehensive haemostatic testing. The effectiveness of the PFA-100 and BT as screening tools in women with menorrhagia was assessed using results of haemostatic testing for von Willebrand's disease (VWD) and platelet dysfunction. In women presenting with menorrhagia, the PFA-100 had a sensitivity 80%, specificity 89%, positive predictive value (PPV) 33%, negative predictive value (NPV) 98% and efficiency 88% for VWD. For platelet aggregation defects, the PFA-100 closure time had a sensitivity 23%, specificity 92%, PPV of 75%, NPV of 52% and efficiency 55%. The data suggest that the PFA-100 may be useful in stratifying women with menorrhagia for further von Willebrand testing; however, neither the PFA-100 nor the BT tests are effective for purposes of classifying women for standard platelet aggregometry testing in women presenting with menorrhagia.

Age and the Prevalence of Bleeding Disorders in Women With Menorrhagia

OBJECTIVE

A study was conducted to evaluate the frequency and types of hemostatic defects occurring in adolescent and perimenopausal-age women diagnosed with menorrhagia.

METHODS

A total of 115 women with a physician diagnosis of menorrhagia, including 25 adolescent women, 25 perimenopausal-age women, and 65 women between the ages of 20 and 44, underwent comprehensive hemostatic testing for possible bleeding disorders. Frequencies of bleeding disorders were calculated and compared.

RESULTS

Forty-seven percent of women were found to have hemostatic abnormalities, including platelet dysfunction, von Willebrand's disease, and coagulation factor deficiencies. Adolescents and perimenopausal-age women with menorrhagia were just as likely to have hemostatic abnormalities as were women aged 20 to 44.

CONCLUSION

These results demonstrate that underlying bleeding disorders are frequently found in adolescent, postadolescent reproductive age, and perimenopausal-age women presenting with menorrhagia and suggest that women with menorrhagia should be considered for further hemostatic evaluation.

The spectrum of bleeding disorders in women with menorrhagia: a report from Western India

In order to evaluate the incidence of hereditary bleeding disorders in patients presenting with menorrhagia, where the usual gynecological and endocrinal causes of bleeding were ruled out by various local ultrasonography (USG) and relevant endocrine investigations, 120 women aged between 18 and 35 years presenting with menorrhagia without any discernable cause were studied using an open design, where the investigators knew that these patients had menorrhagia. These patients were investigated for inherited coagulation defects. Of the 120 women investigated, 19.16% (23 cases) had an inherited coagulation disorder to account for their menorrhagia. Although a majority (11.6%) are patients with von Willebrand's disease (VWD), other rare platelet disorders such as Glanzmann's thrombasthenia (3.3%), Bernard-Soulier syndrome (0.83%), coagulation factor deficiencies such as factor VIII (0.83%), factor X (0.83%), and factor XI (0.83%), and immune thrombocytopenia (0.83%) were also found. Taking a detailed history for bleeding from other sites however minor, paternal consanguinity as well as family history of bleeding tendencies appeared as a very strong predictor for such kinds of disease in patients with menorrhagia. Patients with menorrhagia without a discernable cause, therefore, need evaluation for the congenital coagulation disorders.

von Willebrand disease in women with menorrhagia: a systematic review

OBJECTIVE

To determine the prevalence of von Willebrand disease in women presenting with menorrhagia.

DESIGN

Systematic review of studies evaluating the prevalence of von Willebrand disease in women with menorrhagia.

SETTING

Hospital outpatient clinics (mainly gynaecological) and population surveys.

POPULATION

Women presenting with menorrhagia.

METHODS

Relevant studies were extracted from MEDLINE search, bibliographies of identified articles and published proceedings of meetings and conferences.

MAIN OUTCOME MEASURES

Number of women with von Willebrand disease.

RESULTS

Eleven studies were included, totalling 988 women with menorrhagia. One hundred and thirty-one women were diagnosed to have von Willebrand disease with prevalences in individual studies ranging from 5% to 24%. The overall prevalence was 13% (95% CI 11-15.6%). The prevalence was higher in the European studies-18% (95% CI 15-23%) compared with that in North American studies-10% (95% CI 7.5-13%). This difference (P= 0.007) is likely to be the result of differences in the studies, which include method of recruitment of study population, method of assessing menstrual blood loss ethnic composition of study population, criteria for diagnosis and use of race- and ABO blood group-specific values for von Willebrand factor.

CONCLUSIONS

The prevalence of von Willebrand disease is increased in women with menorrhagia and is the underlying cause in a small but significant group of women with menorrhagia across the world. Testing for this disorder should be considered when investigating women with menorrhagia, especially those of Caucasian origin, those with no obvious pelvic pathology or with additional bleeding symptoms.
