A single-center study of patients with rare isolated acquired clotting factor deficiencies other than acquired hemophilia A. Res Pract Thromb Haemost 2024; 8:102554. [PMID: 39346578 PMCID: PMC11439527 DOI: 10.1016/j.rpth.2024.102554] [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: 04/24/2024] [Revised: 08/01/2024] [Accepted: 08/15/2024] [Indexed: 10/01/2024] Open
Abstract
Background Isolated acquired clotting factor deficiencies (ACFDs) are mainly caused by the existence of anti-factor antibodies or adsorption of clotting factors onto substances such as amyloid. Besides acquired factor (F)VIII deficiency (acquired hemophilia A), the remaining factor deficiencies are rare and diverse, posing challenges in both diagnosis and management. Objectives To describe different features of isolated ACFDs to improve our understanding of these diseases and provide practical recommendations for their management. Methods Clinical characteristics of patients with isolated acquired FII, FV, FIX, FX, FXI, FXII, FXIII, and von Willebrand factor deficiencies were collected from a single center between July 1997 and December 2021 and analyzed retrospectively. Results A total of 54 rare isolated ACFD patients were enrolled in our study, mainly including 20 acquired FV deficiency patients and 16 acquired FX deficiency patients. The median age at diagnosis of all rare isolated ACFD patients was 55 years. The median time to diagnose all rare isolated ACFD patients was 60 days. Ten (18.5%) rare isolated ACFD patients had no bleeding and 2 (3.7%) rare isolated ACFD patients showed venous thromboembolism. Hemostatic treatment was applied to 41 (41/54; 75.9%) rare isolated ACFD patients. Thirty-seven (68.5%) rare isolated ACFD patients received immunosuppressive therapy, and 10 (18.5%) rare isolated ACFD patients received chemotherapy targeting primary diseases. Twenty-two (61.9%) rare isolated ACFD patients achieved complete remission, and 9 (21.4%) rare isolated ACFD patients died. Conclusion Rare isolated ACFDs are underestimated, associated with delayed diagnosis, and lack effective therapy. Clinicians should raise awareness for recognizing and managing rare isolated ACFD patients to avoid morbidity and mortality.

Abstract
Reports on cases of factor Ⅴ (FⅤ) deficiency complicated by platelet function disorders in patients undergoing cardiac surgery are rare, and the utilization of thromboelastography in such cases is limited. This case presents a unique case of FⅤ deficiency complicated by platelet function disorders, highlighting the significance of tailored transfusion strategies guided by thromboelastography (TEG). A 64-year-old hemodialysis patient who was diagnosed with FⅤ deficiency 24 years prior presented for an on-pump coronary artery bypass graft. The decrease in FⅤ activity on preoperative examination was mild. Based on this finding, it was determined that preoperative fresh frozen plasma supplementation was not required. However, the case was complicated by platelet function disorders; therefore, a preoperative transfusion of platelet concentrate was performed to correct the decreased platelet function, enabling subsequent surgery. Intraoperative and postoperative transfusion strategies were guided by TEG. This study highlights TEG-guided transfusion management as a viable option for patients with FⅤ deficiency complicated by platelet function disorders.

Abstract
Rare coagulation disorders pose significant diagnostic challenges emphasizing the importance of clinical vigilance and meticulous hemostatic workup for accurate diagnosis and timely management. We present two cases of exceptionally uncommon coagulopathies - isolated factor V deficiency (F5D) and combined factor V and VIII deficiency (F5F8D). Case 1 features a 24-year-old woman incidentally diagnosed with severe F5D during routine preoperative evaluation for an ovarian cyst. Despite the absence of any reported bleeding manifestations, a timely and accurate diagnosis was rendered. Perioperative management with fresh frozen plasma and postoperative monitoring ensured favorable surgical outcomes. Case 2 features a 10-year-old male presenting with prolonged gum bleeding. Following systematic hemostatic workup, a diagnosis of F5F8D was rendered, thereby guiding optimal therapeutic interventions. We herein aim to contribute valuable insights into the understanding of coagulation physiology and the diagnostic intricacies and management strategies of rare coagulation disorders.

Abstract
Introduction: Acquired factor V inhibitor (AFVI) is a rare autoimmune bleeding disorder. The treatment of AFVI is challenging, and patients often require both bleeding control and inhibitor eradication. Methods: We conducted a retrospective analysis of the medical records of a 35-year-old Caucasian woman who presented with severe AFVI-induced bleeding and subsequent immunosuppressive therapy. Results: To provide haemostasis, rFVIIa was given with good efficacy. The patient was treated with various combinations of immunosuppressive regimens over the course of 2.5 years, including plasmapheresis plus immunoglobulins, dexamethasone + rituximab, cyclophosphamide + dexamethasone + rituximab + cyclosporine, cyclosporin + sirolimus + cyclophosphamide + dexamethasone, bortezomib + sirolimus + methylprednisolone, and sirolimus + mycophenolate mofetil. Although these treatment modalities resulted in intermittent partial reversals of AFVI over 2.5 years, eventually the inhibitor became therapy-resistant. However, following the discontinuation of all immunosuppressive therapy, the patient experienced a partial spontaneous remission, which was followed by a pregnancy. During the pregnancy, the FV activity increased to 54% and the coagulation parameters returned to normal levels. The patient underwent Caesarean section without any bleeding complications and delivered a healthy child. Discussion: The use of an activated bypassing agent for bleeding control is effective in patients with severe AFVI. The presented case is unique because the treatment regimens included multiple combinations of immunosuppressive agents. This demonstrates that AFVI patients may undergo spontaneous remission even after multiple courses of ineffective immunosuppressive protocols. Additionally, pregnancy-associated improvement of AFVI is an important finding that warrants further investigation.

Abstract
Factor V deficiency is a rare bleeding disorder, which may be due to acquired inhibitors or biallelic mutations. Factor V deficiency due to homozygous or compound heterozygous mutation (also known as Owren's disease or parahemophilia) has an estimated prevalence of one in one million people. A 22-year-old female was admitted for evaluation of longstanding menorrhagia. Anatomic abnormalities were excluded, and prolonged prothrombin time (PT) and partial thromboplastin time (PTT) were identified. Mixing studies followed by specific factor assays and genetic testing enable identification of factor V deficiency, for which fresh frozen plasma (FFP) or factor V concentrates are therapeutic. Specific clotting factor assay followed by mixing studies and genetic studies is essential for the diagnosis of congenital factor V deficiency. Deranged PT and activated partial thromboplastin time (APTT) with normal factor I level must be evaluated for the disorder of clotting factors and must be managed by FFP administration or plasma-derived factor V concentrate wherever available.

Abstract
Acquired factor V inhibitor (AFVI) is an extremely rare disorder that may cause severe bleeding. To identify factors associated with bleeding risk in AFVI patients, a national, multicentre, retrospective study was made including all AFVI patients followed in 21 centres in France between 1988 and 2015. All patients had an isolated factor V (FV) deficiency <50% associated with inhibitor activity. Patients with constitutional FV deficiency and other causes of acquired coagulation FV deficiencies were excluded. The primary outcome was incident bleeding and factors associated with the primary outcome were identified. Thirty-eight (74 [36-100] years, 42·1% females) patients with AFVI were analysed. Bleeding was reported in 18 (47·4%) patients at diagnosis and in three (7·9%) during follow-up (7 [0·2-48.7] months). At diagnosis, FV was <10% in 31 (81·6%) patients. Bleeding at diagnosis was associated with a prolonged prothrombin time that strongly correlated with the AFVI level measured in plasma {r = 0·63, 95% confidence interval (CI) [0·36-0·80], P < 0·05}. Bleeding onset during follow-up was associated with a slow AFVI clearance (P < 0·001). The corresponding receiver operating characteristics curve showed that AFVI clearance was predictive of bleeding onset with an AFVI clearance of seven months with a sensitivity of 100% (95% CI: 29-100) and a specificity of 86% (95% CI: 57-98, P = 0·02). Kaplan-Meier analysis showed that AFVI clearance >7 months increased the risk of bleeding by 8 (95% CI: [0·67-97], P = 0·075). Prothrombin time at diagnosis and time for clearance of FV inhibitor during follow-up are both associated with bleeding in patients with AFVI.

Abstract
Development of acquired factor V (FV) inhibitor is a rare coagulation disorder. Production of heteroantibodies against bovine FV, a contaminant in fibrin tissue adhesives, is a common cause of this condition in the field of surgery. The development of recombinant thrombin eliminated contamination of bovine FV, and infrequent use of bovine thrombin has decreased the risk of FV inhibitor development. Here, we report the case of a 43-year-old man who had marked prolongation of prothrombin time and activated partial thromboplastin time after surgery. Mixing coagulation studies with normal plasma and patient’s plasma suggested the presence of an inhibitor. Clotting factor assays revealed that FV activity decreased to <1% with positive FV inhibitor titer (9.2 Bethesda units). The diagnosis of the FV inhibitor was confirmed. Overt bleeding was not observed during the course of hospitalization. His coagulation abnormalities rapidly normalized without any medical intervention. A careful review of his medical records revealed that no tissue adhesives were used in the patient, and the FV inhibitor would likely be autoantibodies. Antibiotic use during the perioperative period or the surgical procedure itself may trigger the occurrence of FV inhibitors. This case highlights that FV inhibitor may develop after the surgical procedure even without a history of the use of fibrin tissue adhesives. Surgeons and hematologists should be aware that this rare but potentially life-threatening condition may occur after the surgical procedure.

Abstract
: To analyze the causative gene and the molecular pathogenesis in a pedigree with compound hereditary coagulation factor V deficiency. Routine blood coagulation indexes and factor V antigen (FV:Ag) were detected by the one-stage clotting method and ELISA. Function of the mutant protein was evaluated by the method Calibrated Automated Thrombogram (CAT). The factor V gene was amplified by PCR with direct sequencing. The possible impact of the mutations were analyzed by bioinformatics tools. The proband's factor V activity and FV:Ag were reduced to 3 and 6%. Gene sequencing revealed compound heterozygous mutations c.911G>A (Gly276Glu) in exon 6 and c.5343C>G (Ser1781Arg) in exon 16. The thrombin generation test showed that the mutant protein markedly decreased thrombin. Bioinformatics indicated that mutations were deleterious. The compound heterozygous mutations Gly276Glu and Ser1781Arg were responsible for the decrease of factor V activity and FV:Ag, of which Ser1781Arg was first reported in the world.

Abstract
Acquired factor V deficiency (AFVD) is a rare autoimmune bleeding disorder. Unlike acquired hemophilia, bypass therapies with recombinant activated factor VII and activated prothrombin complex concentrates are ineffective for severe bleeding due to AFVD. Although several treatment strategies have been attempted, a standard of care for severe hemorrhage induced by AFVD is lacking. Herein, we report a case of AFVD with severe bleeding that responded to plasma exchange (PE) combined with immunosuppression. We also reviewed previously reported AFVD cases with severe hemorrhage and suggest that PE may be an effective initial treatment for AFVD-induced severe hemorrhage.

Abstract
Acquired factor V inhibitor (AFVI) results from the formation of autoantibodies to coagulation factor V (FV), and the clinical phenotype can range from asymptomatic laboratory abnormalities to life-threatening bleeds. We describe a 74-year-old man who developed AFVI along with a massive subcutaneous hematoma. He was initially treated with prednisolone (PSL), but AFVI recurred when the dose was reduced after a short period. We subsequently increased the PSL dose and added cyclophosphamide (CY), which resulted in a complete response. We then gradually tapered PSL and stopped CY, and the patient has since remained free of recurrent AFVI symptoms. We monitored FV activity, antigen concentrations, and inhibitor titers of this patient throughout the clinical course. The ratio of FV activity to antigen concentration was low at diagnosis and gradually increased along with the patient's improvement. This ratio might be a useful parameter for evaluating the effects of immunosuppressive therapy in patients with AFVI.

Abstract
BACKGROUND Acquired factor V deficiency is a rare secondary hemorrhagic disease, which can lead to a severe bleeding disorder.
CASE SUMMARY We report a 47-year-old hemodialysis patient who presented with severe hemorrhagic pleural effusion and hemorrhagic pericardial effusion associated with lymphatic leakage. The laboratory examination revealed decreased factor V activity (2% of population average value). With decreased lymphatic leakage, factor V activity increased (to 46%). Lymph drainage correlated with prothrombin time and active partial thrombin time. The cause of the disease favored an acquired disease. The common causes which trigger factor V inhibitors were excluded. An inhibitor was not detected. It is possible that there was a clotting factor inhibitor leaking with the lymph in the drainage. Inhibitor production may be due to immune dysfunction caused by persistent lymphatic drainage, or that coagulation inhibitors were produced, drained with the lymph, and partly cleared by hemodialysis.
CONCLUSION In this case, we have firstly reported factor V deficiency associated with lymphatic leakage in a hemodialysis patient.

Abstract
Acquired coagulation factor inhibitors are rare. Among them, coagulation factor V (FV) inhibitor is particularly uncommon and presents with variable clinical manifestations. Certain acquired FV inhibitor patients have only mild bleeding or, in select cases, no symptoms at all, leading to spontaneous recovery. Others have life-threatening bleeding that requires medical attention. Thus, a prompt decision regarding diagnosis and clinical intervention is crucial for such patients. In five acquired FV inhibitor cases treated in our facility, each patient had a malignancy as an underlying disease and all unexpectedly showed prolongation of both prothrombin time (PT) and activated partial thromboplastin time (APTT). They all also displayed a discrepancy between PT and Normotest (Hepaplastintest, HPT) results. All but one patient experienced no bleeding at the time of diagnosis and achieved spontaneous recovery in 1-3 weeks. The patient with bleeding symptoms received plasma exchanges and a platelet transfusion. Useful markers in diagnosing the presence of an acquired FV inhibitor were a sudden prolongation of PT and APTT, and a discrepancy between the PT/APTT and HPT assays. Spontaneous recovery can be expected for patients with only minor bleeding.

Abstract
Acquired factor V deficiency is a rare condition associated with a wide variety of causes. We herein report the case of a 75-year-old man who developed acquired factor V deficiency associated with gastrointestinal bleeding after transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma. Laboratory data revealed prolonged prothrombin time (PT) and activated partial thromboplastin time (APTT) and a significant reduction in the factor V (FV) activity. Infusion of fresh-frozen plasma (FFP) was unable to correct the prolonged PT and APTT. Four weeks after onset, his coagulation parameters improved spontaneously with no particular treatment. The patient developed acquired FV deficiency after TACE treatment using cisplatin, and thus, cisplatin was suspected as the cause of this coagulopathy. If coagulopathy that is not corrected by FFP transfusion after TACE is observed, acquired factor V deficiency, although extremely rare, should be considered.
