Spontaneous renal rupture caused by factor VII deficiency: A case report.

RATIONALE: Spontaneous renal rupture is an uncommon disease, it usually occurs after upper urinary calculi-related operation treatment or renal tumor. This disease caused by factor VII deficiency has rarely reported. PATIENT CONCERNS: A 49-year-old woman came to our hospital with on the left flank pain and gross hematuria that had persisted for 10 days. The patient had no recent history of waist and abdominal trauma or surgical history recently. DIAGNOSES: An outside computed tomography (CT) examination revealed left renal rupture before arriving at our hospital, but she was not treated. Further laboratory examination revealed that the patient condition was turned out to be hemophilia caused by factor VII deficiency. INTERVENTION: We have used both internal and external drainage methods, and supplemented with coagulation factor. OUTCOME: After 9 months of follow-up, it was observed that the left renal hematoma and urinary extravasation was completely absorbed. LESSONS: Spontaneous renal rupture for hemophilia is a clinical emergency. When spontaneous renal rupture is associated with abnormal coagulation function, and the coagulation function cannot be corrected by conventional treatment, the possibility of hemophilia needs to be considered, and the type of hemophilia needs to be further defined. This case indicates a successful resolution of spontaneous renal rupture, it can provide guiding value for our clinical practice.

Acquired Factor VII Deficiency Associated With Chronic Myeloid Leukemia Blast Crisis.

Factor VII (FVII) is an important, vitamin K-dependent clotting factor. Acquired FVII deficiency is a rare entity that is associated with serious bleeding complications. We report a case of acquired FVII deficiency in a patient with recurrent chronic myeloid leukemia in blast crisis who developed bilateral retinal hemorrhages. The coagulopathy was corrected with the initiation of chemotherapy and subsequent reduction in peripheral blast count.

Acquired factor VII deficiency in pediatric inflammatory bowel disease: Report of three cases.

Bleeding disorders can exacerbate gastrointestinal bleeding in inflammatory bowel disease (IBD) at the time of diagnosis or flares. Factor VII (FVII) deficiency is a life-threatening rare congenital bleeding disorder in childhood. This study describes three adolescent patients with IBD accompanied by acquired FVII deficiency. This is the first case series of patients with IBD accompanied by FVII deficiency. We hypothesized that inflammation, accelerated consumption, disease severity, and weight loss can cause decreased FVII activity in patients diagnosed with IBD. To control intestinal bleeding, we must keep in mind factor deficiencies in IBD.

Undiagnosed Factor VII Deficiency in Cardiac Surgery Complicated by Bleeding: A Case Report.

Rare bleeding disorders in the perioperative period call for targeted resuscitation strategies. Factor VII deficiency, for instance, is often corrected with exogenous administration of recombinant factor VIIa. This activated clotting factor, initially designed for patients with hemophilia A or B with factor inhibitors, is gaining popularity as a salvage therapy for severe and persistent traumatic and surgical bleeding. This article describes the management of a cardiothoracic surgical patient with undiagnosed isolated factor VII deficiency who experienced significant postoperative bleeding which subsided after the administration of recombinant factor VIIa. In this case, EXTEM failed to detect a clotting factor deficiency.

Acute Thrombotic Events in Association With Coronavirus Disease of 2019 Immunization as Initial Presentation of Congenital Factor VII Deficiency.

Coagulation factor VII (FVII) deficiency is a congenital disorder with heterogeneous clinical phenotypes ranging from asymptomatic to life-threatening bleeding and/or thrombotic events. We present the case of an adolescent male who developed acute deep and superficial venous thromboses of the upper extremities in the setting of multiple peripheral venous line insertions and shortly after receiving his second coronavirus disease of 2019 immunization dose. A hemostatic work-up revealed low FVII activity levels associated with 4 different FVII genetic variants. We highlight the need to better understand the pathophysiologic mechanisms behind FVII deficiency-associated prothrombotic risk and the role that specific FVII genetic variants may play in the clinical presentation of these patients.

Factor VII deficiency: a rare genetic bleeding disorder in a 7-year-old child: a case report.

BACKGROUND: Factor VII deficiency is a rare inherited bleeding disorder that has similar clinical presentation to hemophilia. CASE REPORT: A 7-year-old male child of African origin experienced recurrent nasal bleeding since 3 years of age and recurrent swelling of the joints that was remarkable at the age of 5-6 years. He received multiple blood transfusions and has been managed as a patient with hemophilia until he presented to our facility. Reviewed evaluation of the patient revealed abnormal prothrombin and normal activated partial thromboplastin time, FVII analysis showed activity level of less than 1%, and the diagnosis of FVII deficiency was made. The patient was treated with fresh frozen plasma, vitamin K injection, and tranexamic tablets. CONCLUSION: Even though factor VII deficiency is an extremely rare bleeding disorder, it does occur in our setting. This case highlights the need for clinicians to consider this condition when faced with challenging patients presenting with bleeding disorders.

Paradoxical massive pulmonary thromboembolism in a postpartum woman with factor VII deficiency with bleeding tendency: A case report.

RATIONALE: Factor VII (FVII) deficiency is an inherited bleeding disorder, and women with FVII deficiency are at risk of gynecological bleeding and postpartum hemorrhage. There have been no reports of pulmonary embolism in a postpartum woman with FVII deficiency as of yet. We report a case of postpartum massive pulmonary embolism with FVII deficiency. PATIENT CONCERNS: A 32-year-old woman visited the hospital with premature rupture of membranes at 24 weeks and 4 days of gestation. She was diagnosed with FVII deficiency in an additional blood test after her laboratory results at admission included an increased prothrombin time and international normalized ratio abnormalities. After 12 days of pregnancy maintenance treatment, an emergency cesarean delivery was performed due to uncontrolled preterm labor. The day after the operation, she suffered a sudden loss of consciousness and cardiac arrest, and after she received 1 cycle of cardiopulmonary resuscitation, she was moved to the intensive care unit. DIAGNOSES: She was diagnosed with massive pulmonary thromboembolism with heart failure by chest enhanced computed tomography, C-echo, and angiography. INTERVENTIONS: She was successfully treated with the early application of extracorporeal membrane oxygenation, catheter-guided thrombectomy, and anticoagulants. OUTCOMES: There were no major sequelae over 2 months of follow-up. LESSONS: FVII deficiency does not protect against thrombosis. Due to the high thrombotic risk after childbirth, the risk of thrombosis should be recognized, and thromboprophylaxis should be considered if additional obstetric thrombotic risk factors are present.

Acquired isolated factor VII deficiency in a patient with myxoid pleomorphic liposarcoma, case report.

INTRODUCTION: Acquired factor VII (FVII) deficiency is a rare condition with various causes, including acquired inhibitors to FVII, liver disease, and malignancies. Myxoid pleomorphic liposarcoma is a rare and aggressive form of soft tissue sarcoma that can cause a range of clinical manifestations, including bleeding and clotting disorders. PATIENT CONCERNS AND DIAGNOSIS: We present a case report of a 21-year-old man with severe acquired FVII deficiency due to mediastinal myxoid pleomorphic liposarcoma. The patient presented with elevated International normalized ratio (INR) and a severe reduction in FVII coagulant activity, unresponsive to conventional therapy. While an acquired inhibitor to FVII was initially suspected, negative results from laboratory testing, including protein G sepharose adsorption and a Bethesda assay using Immunoglobulin G purified from patient plasma, made the diagnosis of an acquired inhibitor to FVII uncertain. INTERVENTIONS AND OUTCOME: The patient underwent surgical resection of the tumor, supported by recombinant FVII infusion, leading to the normalization of coagulation parameters. However, a relapse of the disease was detected 6 months later when he was noted to have a decline in FVII levels. CONCLUSION: This case highlights the importance of considering rare causes of bleeding and clotting disorders, particularly in unresponsive or atypical presentations. It also underscores the need for close monitoring and follow-up in patients with acquired FVII deficiency, even after successful treatment.

Thromboelastometry as an Ancillary Tool for Evaluation of Coagulation Status after rFVIIa Therapy in a Pregnant Woman with Severe Hypoproconvertinemia-A Case Series and Review of the Literature.

Introduction: Factor VII (FVII) deficiency is a rare hemorrhagic diathesis. In females, heavy menstrual and postpartum bleeding can appear as a consequence of its deficiency. Supplementation of the recombinant FVIIa is widely accepted. The supplementation effect in FVII-deficient subjects is difficult to predict, and severe hemorrhage has been described even when FVII levels after supplementation were within normal ranges. The aim of this report is to present the application of thromboelastometry to control the coagulation status in a patient with severe FVII deficiency during pregnancy and delivery, supplemented by rFVIIa per protocol complicated with life-threatening venous thromboembolism. Methods: Rotational thromboelastometry (ROTEM) was performed in 16 pregnant women: in one 28 year old primigravida at 35 weeks of pregnancy with congenital FVII deficiency after rFVIIa administration and 15 healthy women at 38 gestational weeks. The results were compared. Results: The thromboelastometry results showed significant shortening of the clotting time in the extrinsic and the intrinsic pathway in the hypoproconvertinemia patient after rFVIIa administration in relation to healthy pregnant women. A significant reduction in maximum lysis of the clot after FVII supplementation was observed. Conclusions: The thromboelastometry results showed a significant hypercoagulable state with hypoproconvertinemia. Thrombotic complications after delivery might be prevented by the reduction in rFVIIa guided by thromboelastometry. Thromboelastometry performed on a pregnant woman with factor VII deficiency during the supplementation of rFVIIa in peripartum time might be helpful in order to determine an individual, effective dosage regimen of rFVIIa to ensure full correction of clotting disorders without the tendency to develop thrombosis, but further studies are needed.

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.

High Prevalence of Congenital Factor VII (FVII) Deficiency in Adolescent Females with Heavy Menstrual Bleeding and Iron Deficiency Anemia.

STUDY OBJECTIVE: To examine the clinical characteristics and prevalence of congenital bleeding disorders (CBDs), with emphasis on congenital factor VII (FVII) deficiency and other rare bleeding disorders, in adolescent and young adult females referred to a hemophilia treatment center (HTC) for evaluation and management of heavy menstrual bleeding (HMB) and iron deficiency anemia (IDA) DESIGN: In this single-center retrospective study, we reviewed the clinical characteristics and prevalence of CBDs in postmenarchal females, younger than 22 years of age, referred to an HTC from 2015 to 2021 for evaluation of HMB with or without IDA. RESULTS: One hundred females, with a mean age of 15 years (range 9-20 years), met initial study criteria, and 95 were included in the final analysis. Forty-five (47%) females were ultimately diagnosed with a CBD. The most prevalent diagnoses were FVII deficiency and type 1 von Willebrand disease (VWD) (42.3%, n = 19 each). Forty-two percent of patients with FVII deficiency had a low-for-age FVII activity level, 21.1% were only positive for the FVII R353Q variant associated with borderline FVII levels, whereas 36.8% had both a low-for-age FVII activity level and a positive R353Q variant. Eighty percent of patients with a CBD were found to have relatives with abnormal bleeding symptoms. CONCLUSION: Congenital FVII deficiency is prevalent among female adolescents experiencing HMB with or without IDA. In addition to VWD, evaluation for this specific factor deficiency should be considered as part of the initial CBD workup. Presence of abnormal bleeding history in the family could also help to predict presence of a CBD.

Epidural analgesia in pregnant with deficit of factor VII.

The congenital deficit of FVII of coagulation it's an anomaly of genetic transmission autosomal recessive type, it can occur with clinical manifestations like hematomas and spontaneous bleeding or not. The normal levels of FVII it's found between 70%-130% of the laboratory reference value. For unknown reasons there is a poor correlation between levels of FVII and bleeding risk. During pregnancy coagulation can be significantly altered, there is a no clear consensus and a very few information about how to act during labor in a patient with a FVII deficit. The case of a 35-year-old patient with 35 weeks of gestation and congenital deficit of the coagulation FVII (36%) is presented, epidural analgesia is performed during labor previously administering activated recombinant FVII (rFVIIa) without complications (Spinal hematoma, postpartum bleeding, thrombosis).

Acquired Factor VII Deficiency Presenting with Bleeding Diathesis in a 52-Year-Old Black Man in Botswana.

BACKGROUND: Factor VII is one of the vitamin K-dependent coagulation factors synthesized in the liver and has a short circulating half-life of 4 - 5 hours. METHODS: We report a case of a 52-year-old black man who presented with life-threatening bleeding from multiple sites. RESULTS: We determined that it was caused by acquired factor VII deficiency of less than 5%. He had a septic pelvic focus which was managed empirically with antibiotics. The bleeding was stopped by fresh frozen plasma and factor VII plasma levels gradually increased to normal levels over the course of 4 months. CONCLUSIONS: We emphasize the importance of extensive evaluation including septic, autoimmune, and malignant work-up in patients with new onset acquired bleeding.

Novel heterozygous F7 gene mutation (c. C1286T) associated with congenital factor VII deficiency: A case report and literature review.

BACKGROUND: Congenital factor VII (FVII) deficiency is a rare inherited autosomal recessive disorder characterized by prolongation of prothrombin time and low FVII coagulation activity, which may increase the risk of bleeding. CASE PRESENTATION: A 66-year-old man with acute postoperative intracranial hemorrhage was transferred to our hospital owing to coagulation dysfunction. In coagulation tests, the FVII coagulation activity was less than 2%. Genetic analysis of the gene encoding FVII identified compound heterozygous mutations: c. 681+1 G>T and c. C1286T (p. Ala429Val). CONCLUSIONS: To our knowledge, this is the first report describing the c. C1286T (p. Ala429Val) mutation in the FVII-encoding gene. We suggest that these mutations resulted in the reduced FVII activity and abnormal clotting in our patient after brain surgery.

Acquired FVII Deficiency and Acute Myeloid Leukemia: A Case Report and Literature Review.

Factor VII (FVII) deficiency is the most common among all rare inherited bleeding disorders. However, acquired FVII deficiency (aFVIID) is uncommon. Only few cases in the literature have been reported. Herein, we present a case of an aFVIID associated with acute myeloid leukemia (AML), along with a literature review regarding this condition. A 50 year old Arab male patient was diagnosed with AML at the hematology department of our institution. At admission, coagulation tests showed a prolonged prothrombin time (PT) with a normal activated partial thromboplastin time (aPTT) and a slightly elevated fibrinogen level. Prothrombin complex coagulation factors dosing (PCCFD) revealed a decrease only in FVII levels. The patient, however, did not experience any bleeding. The evolution of the health of the patient was marked by a normalization of PT and FVII levels and complete remission.

Severe Congenital Factor VII Deficiency with Normal Perioperative Coagulation Profile Based on ROTEM Analysis in a Hepatectomy.

BACKGROUND Factor VII (FVII) deficiency is the most common autosomal-recessive bleeding disorder. FVII activity level (FVII: C) of 10-20% is often used as the threshold for administering activated recombinant FVII (rFVIIa) for patients undergoing major surgery. However, rFVIIa is expensive and carries the risk of a thromboembolic event, and thus should only be administered when truly indicated. CASE REPORT A 22-year-old woman with 8% FVII: C underwent a hepatectomy. Although there were no clinical signs of bleeding, peri-operative administration of rFVIIa was recommended by the hematologist (first dose at surgical incision, then 4 h later, then every 12 h until 48 h postoperatively). Intraoperatively, serials of ROTEM analysis were performed to evaluate the effect of rFVIIa administration. No significant effect of rFVIIa was seen on NATEM. Surgery was unremarkable, without any significant blood loss. The patient developed radial artery thrombosis 24 h postoperatively, the arterial line was removed, and rFVIIa was discontinued (PT: 14.6, FVII: C 36%). On POD 3, INR was elevated (3.15, FVII: C 3%). To correct INR, the patient was transfused 8 units of FFP, despite any signs of clinical bleeding. However, INR and FVII: C did not correct and the patient was discharged on POD 7 in a stable condition. CONCLUSIONS Even with FVII: C of 8%, the ROTEM analysis revealed a normal coagulation status. The administration of rFVIIa did not improve the already normal baseline coagulation profile, but rather potentially led to an accelerated coagulation or hypercoagulable state and may have led to the radial artery thrombosis. We endorse the use of viscoelastic testing for hemostasis assessment and factor replacement in congenital FVII deficiency.

Aortic valve and coronary artery bypass surgery in a patient with factor VII deficiency.

Congenital factor VII (FVII) deficiency is a rare bleeding disorder (RBD) with phenotypes ranging from asymptomatic state to life threatening bleeding episodes. There is no established recommendation for the perioperative management of patients scheduled for cardiac surgery. We have described the perioperative management of a patient with FVII deficiency treated for aortic valve stenosis, coronary artery disease, and atrial fibrillation. Balancing perioperative bleeding risk and risks of thrombotic events thereafter in such patients is difficult and requires a multidisciplinary approach.

Accidentally discovered high INR in pregnancy unmasks an inherited factor VII (FVII) deficiency that is paradoxically associated with thrombotic tendency.

A 32-year-old multiparous obese woman was referred to our center at 37 weeks of twin gestation. She was referred for birth planning following an accidentally discovered high international normalised ratio (INR) in routine preoperative labs. Her history was significant for recurrent pregnancy-associated deep venous thrombosis as well as two early pregnancy losses. Further work-up revealed transaminitis, mild splenomegaly and high lupus anticoagulant titre. A multidisciplinary team of physicians from the high-risk pregnancy, anaesthesiology, haematology, gastroenterology and hepatology departments put a management plan; it culminated into uncomplicated delivery of the patient by repeated caesarian section. The team was also able to figure out the cause of the patient's high INR that is associated with thrombophilia rather than haemophilia.
