[PMID: 38358894 PMCID: PMC10990020 DOI: 10.1097/mbc.0000000000001286] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2024] [Accepted: 02/04/2024] [Indexed: 02/17/2024]
Abstract
As bleeding disorders are a worldwide health concern, Saudi Arabia is experiencing a notable prevalence of such disorders. Studying the frequency and cause of hemostatic disorders is the key to successful clinical interventions and instigating effective public policies that limit the spread of such disorders. The current review aims to highlight the major findings of the body of literature that has investigated the causes, prevalence, and major challenges associated with bleeding disorders in the country. The current review summarizes the major findings of different studies that have been conducted in Saudi Arabia regarding different bleeding disorders. Multiple causes and symptoms of bleeding disorders have been reported by different studies. Some studies investigated the genetic aspect of bleeding disorders and revealed specific mutations in coagulation factor genes influencing the symptoms of different bleeding disorders. Moreover, rare bleeding disorders such as Glanzmann thrombasthenia and Henoch-Schönlein purpura, have been reported in different regions of Saudi Arabia. Combining clinical presentations, genetic factors, and epidemiological data, the current review of the literature provides a comprehensive insight into bleeding disorders in the kingdom. This will help in advancing the diagnostic capabilities and genetic counseling enhancing management strategies and therapeutic interventions benefiting bleeding disorder patients and the kingdom.

Almesedin GS, Alshmaily HO, Alshammari KA, Albalawi RS. Two case reports of Glanzmann thrombasthenia with intracranial hemorrhage and a review of the literature. Surg Neurol Int 2023; 14:448. [PMID: 38213436 PMCID: PMC10783678 DOI: 10.25259/sni_680_2023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2023] [Accepted: 12/07/2023] [Indexed: 01/13/2024] Open
Abstract
Background Glanzmann's thrombasthenia (GT) is a rare autosomal recessive disorder characterized by impaired platelet function. Symptoms range from mild to life-threatening bleeding. However, it is extremely rare for a patient to have intracranial bleeding. This study presents two cases of GT: one with a spontaneous epidural hematoma (EDH) and the other with a subarachnoid hemorrhage due to traumatic causes. The discussion that follows then derives relevant supporting insights through a review of the literature. Case Description Case Report 1: A 9-year-old girl with a known case of GT presented to an emergency department with a severe headache but no other complaints or history of trauma. The physical examination was normal. Computed tomography (CT) head without contrast revealed multiple EDHs with no midline shift. She received factor VII, tranexamic acid, and platelets transfusion and was admitted to the intensive care unit to be managed conservatively. After a month, a CT head follow-up showed complete resolution of all hematomas. Case Report 2: A 20-year-old male with a known case of GT was brought to the hospital with a history of loss of consciousness for several minutes after a road traffic accident. He suffered from a headache on regaining consciousness and received analgesia. CT head showed diffuse subarachnoid hemorrhage. He was managed with factor VII, tranexamic acid, and platelets transfusion and was admitted to an intermediate care unit for close observation. Conclusion In a GT patient with intracranial hemorrhage, conservative management with close clinical observation and platelet transfusion in combination with recombinant activated factor VII and/or antifibrinolytics can be safely conducted.

Abstract
ABSTRACT Prevalence of bleeding disorders vary due to several factors including geographical location. Mild bleeding disorders can lead to iron deficiency, morbidity, and in severe cases mortality. Quantification of haemorrhagic symptoms is a key component in management of bleeding disorders and a challenging task for clinicians.An abridged version of MCMDM-1vWD questionnaire with validated Arabic translation was used to quantify bleeding disorders in adult students (n = 1138) in 4 different regions of Kingdom of Saudi Arabia. Statistical analysis was performed to indicate gender disparity and prevalence.74.5% of respondents answered at least 1 question with affirmation, with 32.3% affected in Riyadh showing the highest prevalence and 14.03% affected in Dammam showing the least prevalence (P-value < .001). Gender-wise, higher prevalence of bleeding disorders in females 54.9% than in males 45.1% was observed (P-value .01). Epistaxis prevalence was significantly higher in males 30.7% vs 23.2% in females (P-value .0004), while cutaneous symptoms were reported significantly more by female participants 29.7% vs 12.3% in males (P-value < .001). Menorrhagia was reported by 28% of females, with heavy bleeding experienced by 57.6% female participants for <7 days while in 42.4% of females for >7 days.The current study signifies the ethnic distribution and gender disparity of mild bleeding disorders, and highlights the need for national surveillance system in order to improve management of patients with bleeding disorders.

Abstract
Bernard-Soulier syndrome is a rare autosomal recessive bleeding disorder and has a low incidence. Bernard-Soulier syndrome is caused by the deficiency of glycoprotein GPIb-V-IX complex, a receptor for von Willebrand factor and is characterized by thrombocytopenia, giant platelets and bleeding tendency. We are reporting three members of a same family with variable phenotypic clinical presentation. The index case is a 20-year-old boy who has a frequent presentation with epistaxis, and low platelet counts (25 × 109/l). He had been hospitalized multiple times and received platelet transfusions. His brother and cousin reported bleeding symptoms with less frequent medical intervention. Genetic analysis by next-generation sequencing identified a homozygous GP1BB variant (c.423C>A:p.Cys141Ter), which segregated amongst the family members. The results led us to an improved insight into the disease for this family with variable phenotypic expression, in addition to the identification of a variant for further structural and functional characterization.

Inherited Bleeding Disorders in Pediatric Patients; experience of the national referral center in Iraq. Indian J Hematol Blood Transfus 2021; 37:96-100. [PMID: 33707841 DOI: 10.1007/s12288-020-01306-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2020] [Accepted: 06/06/2020] [Indexed: 10/24/2022] Open
Abstract
Background Inherited bleeding disorders can lead to lifelong bleeding; they are mainly caused by quantitative or qualitative defect of coagulation factors, von Willebrand factor (VWF) or platelets. No published data are available about the different types of inherited bleeding disorders in Iraq. Objectives To describe types, severity and presentation of inherited bleeding disorders in pediatric patients in the major referral center in Iraq. Patients and Methods This is a cohort prospective descriptive study conducted at the National Center of Hematology, a referral center for bleeding disorders in Baghdad-Iraq, from January 2015 to December 2019. One hundred ninety-one patients, aged 1 day to 14 years, with suspected inherited bleeding disorder are included in this study. Each patient was interviewed, accompanied by a chaperone, mostly parent(s), with revision of personal and familial bleeding history, conducting a brief medical examination, and withdrawing blood for complete blood count, peripheral blood film, bleeding time, PT and APTT. Further investigations including mixing studies, lupus anticoagulant, clotting factor activity, VWF:antigen (VWF:Ag), VWF: Ristocetin cofactor (VWF:RiCof) and platelet function tests using light transmission aggregometry were performed only if indicated. Results The mean ± 1SD of age of patients is 5.3 ± 3 years, with a male:female ratio of 1.3:1. Family history of a similar bleeding disorder is recorded in 44.9% patients (P < 0.05). Consanguineous marriage was observed in 70.8% of the families (P < 0.001). The most prevalent inherited bleeding disorder is von Willebrand disease (VWD) (43.9%), of which type 3 is the most common (86.9%). Thrombasthenia is the second most prevalent (39.8%) inherited bleeding disorder; of these, the majority have Glanzmann's thrombasthenia (82.9%). Hemophilia A is found in 9.4% of patients. Conclusion Type 3 VWD, Glanzmann's thrombasthenia and hemophilia A are the most common inherited bleeding disorders in the central part of Iraq, collectively they constitute >86% of patients. Consanguineous marriage should be discouraged in our society to decrease hereditary bleeding disorders. Also, there is a need to increase awareness and knowledge of bleeding disorders to improve early identification, mitigate the risk of further bleeding and prevent complications.

Abstract
Bleeding tendency is a common medical problem that is usually caused by either coagulation factors abnormalities, platelets disorders, or vasculopathy. Detection of patients with high bleeding risk through history taking and accurate diagnosis followed by appropriate management will help decreasing chances of significant complications. Methodology A cross-sectional survey of a random sample of adolescent students in the preparatory year at Taibah University in Almadinah Almunawwarah, Saudi Arabia were interviewed using a validated semi-structured condensed bleeding tendency questionnaire generated from Molecular and Clinical Markers for the Diagnosis and Management of (MCMDM-1). Results A total of 680 questionnaires were collected, the phase I data were analyzed to determine participants who gave a positive response to any related question while in Phase II respondents with at least one positive response of any bleeding symptom were interviewed. More than half 52.6% (358 out of 680) were positive for any bleeding symptoms. The incidence rose to 70.9% (482 out of 680) if "Mild" symptoms were also included. Epistaxis was positive in 21.8%, Cutaneous symptoms were reported by 22.65%, Bleeding from the oral cavity was reported in 39.6%, Gastrointestinal bleeding was observed by 5.9%, bleeding after the first surgery reported in 21% and Muscle hematomas/hemoarthrosis was observed by 3.2%, Among female papulation, 16.1% reported having 6-10 "Heavy Days" during their menstrual cycles. Discussion High prevalence of bleeding symptoms having the possibility of the presence of an Inherited Bleeding Disorders were observed in our study in comparison to other studies, this might be attributed to the high percentage of consanguinity marriages in our area. Recommendations Raising awareness among family doctors and pediatricians about the possibility of presence of bleeding tendency utilizing good history taking followed by appropriate examination and laboratory confirmatory testing will help in early detection and managements.

Abstract
Factor XII (FXII) deficiency is a rare genetic blood disorder. It can lead to a higher risk of developing deep vein thrombosis or acquired thrombotic disorders than the general population. This retrospective study evaluated patients who opted for surgery and were found to have abnormal clotting profiles and clotting factors on preoperative routine blood. Patients were included regardless of whether they were symptomatic or asymptomatic. The cohort comprised 115 patients with a mean FXII level of 128.04 ± 36.93%. Two (1.79%) patients, both of whom were women, had FXII levels <60%. The mean FXII level was 58 ± 1.41 (range, 57–59%) in this group. The present study shows the prevalence of FXII in the asymptomatic Saudi population. The results provide the normal range for FXII. The findings of our study provide the basis for diagnosing F XII deficiency in the asymptomatic Saudi population.

Abstract
Introduction
Inherited bleeding disorders vary in prevalence due to genetic disparity and ethnicity. Little is known about the prevalence of coagulation factor deficiency and bleeding disorders in middle-eastern population.
Methods
Young Saudi adults with at least one positive bleeding symptom reported in semi-structured validated condensed MCMDM-1vWD questionnaire were tested for complete blood count, routine and special coagulation tests, serum ferritin level, and capillary zone electrophoresis. After initial testing, those with prolonged prothrombin time (PT) or activated prothrombin time (APTT) had further testing to evaluate coagulation factors level. Platelet function was tested through platelet function analyzer (PFA)-100, and multiplate aggregometer (MEA) on patients suspected of having platelet disorders.
Results
Six-hundred-forty patients (male = 347, 54.2%) were included. A possible platelet function defect was diagnosed in three patients with one matching Glanzmann's thrombasthenia trait pattern, and one that of Bernard-Soulier trait pattern. One patient was diagnosed with von Willebrand disease. Deficiencies in coagulation factor levels were revealed as F-VIII in 14 (7.4%), F-IX in 15 (7.6%), F-II in two (3.3%), F-V in 17 (26.1%), FVII in two (3.1%), and F-X in one (1.8%) of study subjects; low vWF activity (<50%) was found in 14 (8%). Abnormal values were found for various laboratory tests with prolongation of platelet function analyzer-epinephrine (PFA-EPI) in 11%, PFA-ADP or arachidonic acid in 15.2%, PT in 35.9%, and APTT in 63.7%. Five-hundred-seventy-six patients (90%) had normal results in the coagulation factor assays and were categorized as patients with bleeding of unknown cause (BUC). A diagnosis of a bleeding disorder was more frequently made in men than in women (38 vs. 26). Iron deficiency anemia was found in 18 (25%) females positively associated with F-IX deficiency (
p
-value 0.000). Male gender (73.3%,
p
= 0.007) was independently associated with the diagnosis of coagulation factor deficiency.
Conclusion
The current study reports a higher prevalence of coagulation factors deficiency in Saudi population than reported in the western population.

Abstract
Glanzmann thrombasthenia (GT) is a rare autosomal recessive bleeding disorder. Around 490 mutations in ITGA2B and ITGB3 genes were reported. We aimed to use targeted next-generation sequencing (NGS) to identify variants in patients with GT. We screened 72 individuals (including unaffected family members) using a panel of 393 genes (SHGP heme panel). Validation was done by Sanger sequencing and pathogenicity was predicted using multiple tools. In 83.5% of our cohort, 17 mutations were identified in ITGA2B and ITGB3 (including 6 that were not previously reported). In addition to variants in the two known genes, we found variants in ITGA2, VWF and F8. The SHGP heme panel can be used as a high-throughput molecular diagnostic assay to screen for mutations and variants in GT cases and carriers. Our findings expand the molecular landscape of GT and emphasize the robustness and usefulness of this panel.

Abstract
Background Bleeding disorders vary in prevalence. While some are rare, some can be common in both sexes. Most bleeding disorders manifest as chronic bleeding tendencies or as an increase in bleeding during surgical procedures or trauma. The consequences of bleeding can be as simple as iron deficiency or catastrophic, resulting in severe morbidity and mortality. Bleeding disorders typically affect both sexes except hemophilia A and B, which mainly affects males. Method We conducted a questionnaire-based survey among adolescents and young adults (1901 [49%] boys, 1980 [51%] girls) in Riyadh city regarding bleeding symptoms. Of these, 1849 (47.6%) responded “Yes/Positive” for at least one question about the bleeding symptoms. Results The most common bleeding symptom was epistaxis (19.7% of the sample population) detected in Phase I of the study. A tandem survey was conducted among 525 adolescents who had responded “Yes/Positive” to any one of the questions inquiring about bleeding symptoms. Conclusion In this study, we report for the first time the prevalence of bleeding symptoms in a representative sample of Saudi adolescents and young adults.

Abstract
The objective of the present study was to investigate the prevalence of bleeding symptoms in individuals who are heterozygous for recessively inherited coagulation disorders (RICDs) and to determine the association of these bleeding symptoms with type of RICDs. This was a retrospective cross-sectional study being performed in Shiraz Hemophilia Society (Shiraz, Southern Iran). In this study, bleeding symptoms of the parents (heterozygous) of the patients (homozygous) who were registered and had definite diagnosis as autosomal recessive coagulation disorder were evaluated. These inherited disorders include factor I, V, VII, X, XI, XIII deficiency, combined factor VII and X deficiency, combined factor V and VIII deficiency, all platelet disorders and von Willebrand disease (VWD) type III. 50.3% individuals underwent genotype and mutation study to confirm their heterozygosity. We included 350 heterozygote individuals for inherited coagulation disorders among whom there were 175 (50%) men and 175 (50%) women. Those who were heterozygous for factor VII deficiency had significantly higher prevalence of subcutaneous hematoma (P=0.011). In the same way heterozygous patients for Bernard-Soulier syndrome had higher prevalence of hypermenorrhea (P=0.012) and obstetric (normal vaginal delivery or cesarean delivery) bleeding (P=0.012). Heterozygosity for factor X and XIII deficiency was associated with prolonged or massive bleeding during operations (P=0.001) and after minor traumas (P=0.019), respectively. Heterozygosity for RICDs is associated with some bleeding symptoms. Thus bleeding tendency and homeostasis disturbance should be kept in mind in those who are heterozygous for RICDs and more preoperative care and correction of coagulation indices is highly recommended.

Abstract
The objective of the present study was to determine the pattern of inherited bleeding disorders in southern Iran and evaluate the effect of a comprehensive coagulation laboratory and related efforts. A total of 545 patients with inherited bleeding disorders were evaluated during 1992-2007 by a cross-sectional study. Data were collected by a data-gathering form. Statistical analysis was done using Statistical Package for the Social Sciences version 15. A P value less than 0.05 was considered statistically significant. Overall 411 patients had common bleeding disorders including 326 hemophilia A, 46 hemophilia B, and 39 von Willebrand disease. Seventy-nine patients had rare coagulation disorders including deficiency of factor VII (n = 26), factor X (n = 18), factor XIII (n = 9), factor I (n = 9), factor XI (n = 7), factor V (n = 4), combined factor VIII and factor V (n = 4), and combined factor X and factor VII (n = 2). Fifty-five patients had platelet disorders including 23 with Glanzmann's thrombasthenia, 15 with Bernard-Soulier syndrome, and 17 with other platelet disorders, most of which (45) were diagnosed after the establishment of the comprehensive coagulation laboratory. Annual mean number of new diagnosed patients with common and rare bleeding disorders increased from 29 +/- 4 to 38 +/- 17. The ratio of the patients diagnosed with rare bleeding disorders to common bleeding disorders significantly increased after the establishment of the comprehensive diagnosis laboratory (P < 0.001).It seems that implementation of collaborative projects by the Shiraz Hemophilia Society and the establishment of the comprehensive coagulation laboratory and treatment centers have been successful in increasing diagnosis of the inherited bleeding disorders and consequently better management of the patients.

Abstract
Hemophilia represent the most severe inherited bleeding disorder (INB), it's thought to affect inviduals from all geographical areas in equal frequency. In Egypt which has a population of approximately (80million) consanguineous marriage are frequent, therefore autosomal recessive coagulation disorders reach a higher prevalence than in many other countries.The primary aim of this study was to describe the epidemiological situation of hemophilia in Mansoura, Egypt, as based on retrospective analysis of clinical records Mansoura University Children Hospital between years 2000 and 2008. The second aim was to assess the orthopedic complications and occurrence of hepatitis C in those patients and relate this status to the type of replacement therapy received prior to the study.The study included 72 children with hematological disorders registered from 2000 to 2008 in MUCH. The hemophilic patient was defined as a person with physician-diagnosed hemophilia A or B and a measured factor VIII or IX activity level of 30% or less. Persons with acquired inhibitors of FVIII or FIX excluded. Severity level was categorized as mild if the factor activity level was 6-30%, moderate if 1-5% and severe if <1% of normal.The severe presentation represents the majority in 76.7% followed by moderate severity in 17.2%. The commonest IBDs was hemophilia A affecting 44 patients, followed by Hemophilia B affecting 15 patients. The rare types were Factor XI deficiency, Factor V deficiency, Factor VII deficiency and combined FVIII, FIX and FX deficiency. The commonest orthopedic manifestation needing therapy was found among hemophilia A representing 8.3%. Hepatitis C viremia detected by PCR was found in 11.1% of patients. The bleeding complications as hematoma or hemarthrosis were the common complications. Nevertheless, 44.4% of patients had no complications, From this study we can conclude that the most common IBDs in our locality is hemophilia A followed by hemophilia B. The common presenting symptom was bleeding following male circumcision. Hepatitis C infection and arthropathy represented the main complications. The discovery of IBDs in young age children with proper supportive therapy could prevent arthropathy. Proper screening of blood and blood products reduce the risk of viral hepatitis and HIV acquisition.

Abstract
Inherited bleeding disorders (IBDs) are caused by quantitative and qualitative alterations of either platelets or plasma proteins involved in coagulation and fibrinolysis. Hemophilias are the most frequent IBDs; however, accumulated data from various studies reported that von Willebrand disease (VWD) is the most common cause of IBD, with an increased incidence of platelet function defects, mostly due to the increased rate of consanguinity in some communities. VWD is an inherited disorder of homeostasis due to quantitative or qualitative defect of von Willebrand factor. Data on its epidemiology and impact in developing countries are limited. The objective of this study was to assess the local prevalence of some IBD and establish the clinical and historical variables that are predictive for those bleeding disorders in pediatrics. The study involved 43 children with various bleeding manifestations and 15 age- and sex-matched controls, recruited from the Pediatrics Hematology Clinic at the National Research Centre, Sausan Mubarek children's hospital in Cairo, Egypt and the King Abdulaziz University Hospital, Jeddah, Kingdom of Saudi Arabia. Hematological profile included platelet counts and function, prothrombin time, partial thromboplastin time, factor VIII antigen and its activity, factor IX antigen and its activity, von Willebrand factor and its activity assayed with multimeric analysis. A total of 12 (27.9%) children had VWD, 11 (25.5%) had hemophilia A, three (7%) had hemophilia B, seven (16.3%) had platelet dysfunction and 10 (23.3%) had bleeding with undiagnosed cause. Two of the VWD cases had type I, three had type II, four had type III and one case appeared to have type IIM and another to have IIB VWD. Bruising and epistaxis were the main symptoms in all children with VWD The majority of platelet dysfunction disorders were diagnosed as Glanzmann's thrombasthenia. VWD and Glanzmann's thrombasthenia should be considered not uncommon causes of IBDs in children in Egypt and Kingdom of Saudi Arabia. Routine hematological screening should be mandatory in children with positive family history of bruising and bleeding as a predictor for IBD.

Abstract
von Willebrand disease (VWD) is considered to be the most common inherited bleeding disorder. Data on its epidemiology and impact in developing countries are limited. The biologic heterogeneity and variable presentation of VWD make diagnosis difficult. Although there is no accurate estimate of the prevalence of VWD in developing countries, available data suggest that the proportion of diagnosed cases is lower than the expected number, often accounting for only 6% to 13% of patients with hereditary bleeding disorders. Although accurate subtyping is often not possible, the number with severe disease tends to be much higher, particularly in those parts of the world where consanguinity is common. Agents used to treat patients with VWD range from plasma to purified factor concentrates. Desmopressin (DDAVP) is commonly used. Preliminary data on molecular genetics suggests that there are significant population differences. There is inadequate awareness of this condition and lack of support for these patients from the health care system in many developing countries. Concerted efforts are needed at the scientific and social levels to improve this situation.
