Abstract
Acquired hemophilia A (AHA) is a bleeding disorder characterized by the immunological inhibition of factor VIII (FVIII) of the hemostatic pathway leading to hemorrhagic events. Different domains of FVIII are the target of autoantibodies (mainly immunoglobulin (Ig) G) leading to the deficiency of FVIII. Several factors have been associated with the activation of the auto-immunity towards FVIII. Emerging evidence implicates CD4+ T cell activation in mediating this autoimmune response, with their involvement like that observed in congenital hemophilia A. Several genes such as HLA II DRB*16, DQB1*0502, and CTLA-4 + 49 are responsible for the pathogenesis of AHA. Epigenetic modifications and mainly long-coding RNAS (lncRNAs) are potentially contributing to the pathogenesis of AHA. The treatment approach of AHA includes the management of acute bleeding events and the administration of immunosuppressive medications. This review aimed to summarize the published data on the genetics and epigenetics of AHA. The severity and the mortality of this disease are creating an emerging need for further research in the field of the genetics and epigenetics of acquired hemorrhagic disorder.

Abstract
This survey study aimed to evaluate the level of awareness and knowledge of acquired hemophilia A (AHA) among physicians from various specialties. Data were collected by administering a questionnaire containing questions about two patient profiles to evaluate the approaches of physicians from different specialties. The study included a total of 945 physicians. The most common suspected diagnosis for the clinical patient profile was immune thrombocytopenia, followed by hemophilia. For the laboratory patient profile, the most common suspected diagnosis was hemophilia. While only 9.4% of the physicians stated that they had good knowledge of this disease, only 21.6% wanted to learn more about AHA. Most of the participating physicians do not rank AHA first in the differential diagnosis of a patient with clinical and laboratory findings of AHA. Appropriate educational activities to raise awareness of AHA will help reduce disease-related morbidity and mortality.

Abstract
Acquired hemophilia A (AHA) is an ultra-rare autoimmune disorder caused by autoantibodies against factor VIII. It often presents with life-threatening bleeding to non-hemophilia experts, who have limited awareness of this condition. This review evaluated hemostatic management and identified barriers to optimal management of AHA by non-hemophilia experts in the United States through a literature review. AHA case reports published by non-hemophilia experts from January 2016 through November 2021 in non-hematology journals were critically reviewed for a chronology of clinical course and management, consultation with a hemophilia expert, referencing of available AHA recommendations, discussion of all hemostatic options, and bleed control outcomes; 24 case reports representing 24 patients were identified. Twelve patients had an apparent delay in diagnosis, 17 cases did not seek expert consultation, and 15 did not reference the 2009 International AHA Recommendations, including six in whom hemostatic treatment was not consistent with the recommendations. Of the 17 articles published after the 2017 AHA Guidance, eight did not reference them. Of the five articles published after the 2020 International Recommendations for AHA, three did not reference them. Overall, 14 articles did not discuss all available hemostatic treatment options. Four patients died. Our findings reveal variability in hemostatic management of AHA by non-hemophilia experts in the United States. Lack of AHA awareness remains a primary barrier for optimal management of AHA among non-hemophilia experts. Increasing education about existing AHA guidelines, including available therapies and access to expert care at hemophilia treatment centers, may help improve the outcomes of patients with AHA.

Abstract
Acquired haemophilia A is a rare condition defined by the presence of coagulation inhibitors, which are autoantibodies directed against factor VIII that interfere with its activity. We report a case of a 69-year-old woman that presented with knee haemarthrosis followed by spontaneous retroperitoneal haematoma. On coagulation studies, she presented normal prothrombin time with prolonged activated partial thromboplastin time non-correcting on mixture test, low titers of factor VIII and was detected factor VIII inhibitor that led to diagnosis of acquired haemophilia A. She was managed with supportive measures to control haemorrhage and immunosuppressive therapy to eradicate inhibitors, initially with corticosteroids, with partial transitory response, after which she developed new spontaneous haematomas. Rituximab was started at that time, with a good outcome. The additional aetiological study identified autoimmune thyroiditis and autoimmune pangastritis, an association rarely described in literature.

Abstract
BACKGROUND Acquired haemophilia A is a rare bleeding disorder caused by the development of specific autoantibodies against coagulation factor VIII. Standard treatment, usually steroids alone, or in combination with cyclophosphamide, aims to stop acute bleeds by using haemostatic agents to promote clotting. Rituximab may be an alternative approach to the treatment of acquired haemophilia by eradicating FVIII autoantibodies. This is an update of a previously published Cochrane Review. OBJECTIVES To assess the efficacy and adverse effects of rituximab for treating people with acquired haemophilia A. SEARCH METHODS We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's trials registers, comprising references identified from comprehensive electronic database searches and handsearches of relevant journals and conference proceedings (January 2021). We also undertook searches of CENTRAL, MEDLINE and online trial registries (January 2021). SELECTION CRITERIA Randomised and quasi-randomised controlled trials of rituximab for people with acquired haemophilia A, with no restrictions on gender, age or ethnicity. DATA COLLECTION AND ANALYSIS No trials matching the selection criteria were eligible for inclusion. MAIN RESULTS No trials matching the selection criteria were eligible for inclusion. AUTHORS' CONCLUSIONS We found no randomised clinical trials of rituximab for acquired haemophilia A. Thus, we are not able to draw any conclusions or make any recommendations on rituximab for eradicating inhibitors in people with acquired haemophilia A based on the highest quality evidence. Given that undertaking randomised controlled trials in this field is a complex task, we suggest that, while planning such trials, clinicians treating the disease continue to base their choices on alternative, lower-quality sources of evidence. In a future update of this review, we plan to appraise and incorporate eligible randomised controlled trials, as well as other high-quality, non-randomised studies.

Abstract
Acquired haemophilia A (AHA) is an uncommon but severe acquired bleeding disorder caused by the development of antibodies against clotting factor VIII, impairing secondary haemostasis. It is more common in older individuals and characteristically presents with spontaneous soft tissue bleeding that can rapidly become life-threatening. Definitive treatment requires immunosuppression to eradicate anti-FVIII antibodies, while providing haemostatic support to manage bleeding. Transfusions of fresh frozen plasma or cryoprecipitate, typically used to treat severe bleeding, are ineffective in patients with AHA. Instead, highly specialised clotting factor concentrates are required. While the appearance and extent of the soft tissue bleeding and the markedly prolonged activated partial thromboplastin time are characteristic, lack of familiarity with this disease process can lead to significant treatment delays. We report the clinical course and management of a 65-year-old woman who presented with severe anaemia of unclear aetiology with unrecognised soft tissue bleeding who was subsequently diagnosed with AHA.

Abstract
BACKGROUND Acquired haemophilia A (AHA) is a rare immune-mediated disorder characterised by the development of autoantibodies against factor VIII. Morbidity and mortality are in general high due to multiple factors including the age of the patient, underlying diseases, toxic effects of available treatments and bleeding itself. OBJECTIVE To assess the awareness about AHA among healthcare professionals (HCPs) in Lebanon where patients can present to non-haematologists with life-threatening bleeding disorders. METHODS A cross-sectional survey was conducted in September and October 2017 all over Lebanon among HCPs. The survey covered: (i) the geographic area of practice and specialty; (ii) bleeding disorders encountered within the last 2 years; (iii) assessment of knowledge on AHA; and (iv) importance of increasing awareness on AHA among HCPs. RESULTS A total of 362 participants completed and returned the questionnaire (response rate 100%). The majority of the HCPs were practicing in Beirut (n=164; 45.3%) and were internists (n=106; 29.3%). 332 (93%) HCPs have encountered patients with bleeding problems within the last 2 years all over Lebanon. 327 (92.1%) HCPs agreed that increasing awareness on AHA among health care professionals is important. HCPs gave an average of 75.9% of correct answers on the survey. CONCLUSIONS Appropriate treatment and diagnosis are essential when dealing with AHA. Knowledge gaps exist in the clinical practice when dealing with patients who have AHA. This study shows the need for increasing awareness about AHA among HCPs in Lebanon regarding the diagnosis and treatment of this disorder.

Abstract
Acquired Hemophilia A (AHA) is a rare entity, resulting from the production of autoantibodies against Factor VIII of the coagulation cascade. These autoantibodies may develop in response to autoimmune conditions, drugs, neoplastic diseases, and pregnancy. Diagnosis involves clinical presentation, mucocutaneous or intramuscular bleeding, and laboratory findings, such as prolonged activated partial thromboplastin time, decreased levels of Factor VIII, and the presence of Factor VIII autoantibodies. The etiology is diverse, with a variety of underlying culprits. Malignancy-associated AHA has been associated with approximately 15% of cases. Urothelial malignancy-mediated AHA is exceedingly rare, with only two previously published reports. The management of AHA includes stabilization and control of bleeding via the use of hemostatic agents, and elimination of the inhibitor with immunosuppressive therapy. Here, we report a case of AHA secondary to urothelial malignancy and review the pathobiology and pathogenesis of Hemophilia A and AHA.

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
We report a case of acquired factor XI deficiency with lupus anticoagulant (LA) in a 28-year-old primigravida who presented with finger pain and eruptions on her palms and fingers during the 3rd trimester of pregnancy. The patient complained of pain and reddening of the fingers at 30 weeks of gestation. She was referred to our tertiary center with a diagnosis of preeclampsia and suspected collagen disease at 35 weeks of gestation. Erythema was seen on the fingers and palms, and she presented with pain and cryesthesia on the fingers. Laboratory investigations revealed an activated partial thromboplastin time of 51 s (normal, 23–40 s), although it was normal during the 30th and 34th gestational weeks, LA with an anticardiolipin-beta2-glycoprotein I complex antibody, and low level of clotting XI activity (25 U/mL). On week 37 day 0 of gestation, the patient presented with severe hypertension. An urgent Cesarean section was performed after transfusion of two units of fresh frozen plasma. There was no excessive bleeding during the surgery or the postpartum period. The symptoms on her fingers and palms gradually improved after surgery. Our case indicates that dermatoses of pregnancy may become a starting point for the diagnosis of autoimmune diseases and coagulation abnormalities. When a patient presents with an atypical symptom, as in our case, the possibility of various diseases should be considered.

Abstract
RATIONALE Acquired hemophilia A (AHA) is a rare autoimmune disease caused by autoantibodies directed against the activity of factor VIII (FVIII) and presents with prolonged bleeding. 5.7% of systemic lupus erythematosus (SLE) patients are affected by AHA. PATIENT CONCERNS A 51-year-old female patient with SLE presenting with the fatigue and spontaneous clinical bleeding symptoms such as hematuria and ecchymoses for 1 week. DIAGNOSIS Laboratory examinations revealed prolongation of the activated partial thromboplastin time (APTT) (65.7 s), decreased FVIII activity (1.4%), and a titer of FVIII inhibitors of 8.5 Bethesda units/mL. INTERVENTIONS Transfusion of recombinant human FVIII (ADVATE) in combination with intravenous methylprednisolone, cyclophosphamide, plasmapheresis, and fresh frozen plasma successfully stopped the bleeding and reduced the level of FVIII inhibitor. OUTCOMES The size of the hematoma slowly decreased. The skin ecchymosis was gradually absorbed, the hemoglobin count increased, and the coagulation index gradually improved. There was no new bleeding or bleeding site. The patient was discharged and transferred to a local hospital for hospice care. LESSONS AHA in a patient with SLE is rare. Once it occurs, it can be life-threatening. Clinicians should remain aware that because some cases of AHA may have features of SLE, appropriate distinction and diagnosis of these different but associated diseases is necessary.

Abstract
Acute gastrointestinal bleeding (GIB) is a frequently encountered medical emergency and it can be life-threatening depending on the etiology and the clinical condition of the patient. The most common causes of GIB are peptic ulcer disease, aspirin-induced gastritis, variceal hemorrhage, esophagitis, neoplasms like gastric cancer. Acquired hemophilia causing acute gastrointestinal bleed is extremely rare and only a few cases are reported worldwide. Acquired hemophilia A (AHA) is a rare disorder caused by the production of autoantibodies that inactivates clotting factor VIII. We present a case of upper gastrointestinal bleed due to AHA which was undiagnosed for two years. A 74-year-old patient with a history of myasthenia gravis, presented with anemia, and GIB. She underwent multiple endoscopies without a clear bleeding source. Coagulation studies showed isolated activated partial thromboplastin time prolongation which was not corrected by mixing study. Factor VIII activity was low and Bethesda titer showed elevated inhibitor levels. Factor Eight Bypassing Agent, recombinant factor VIIa, and steroids were given to control bleeding. Her clinical condition worsened, and she passed away. Elderly patients presenting with an undiagnosed source of GIBs, inconclusive endoscopic studies should be evaluated for acquired coagulopathies, especially in those with a history of autoimmune diseases and malignancies. Prompt diagnosis and treatment are warranted as it carries a high mortality. Part of the case presentation was presented as an abstract at a regional conference

Abstract
Acquired hemophilia is a rare autoimmune bleeding disorder related to the production of autoantibodies that inhibit clotting factor VIII or IX. The underlying cause can be autoimmune disease, malignancy, pregnancy, or medications, but it is most commonly idiopathic. Here we present the case of an 81-year-old patient with locoregionally relapsed periampullary carcinoma who presented with soft tissue hematoma and an abnormally elevated activated partial thromboplastin time (aPTT) in the presence of a normal prothrombin time. A diagnosis of acquired hemophilia was established. The patient was managed with immunosuppressive prednisone and cyclophosphamide plus immunoglobulin G. He also received a cycle of chemotherapy with gemcitabine and oxaliplatin, because the underlying malignancy was the cause of the bleeding disorder. Care was complicated by neutropenia and nosocomial fever, but the patient eventually showed signs of clinical stability, while the aPTT decreased 2-fold. The patient was successfully discharged from the hospital and continued treatment in outpatient care.

Abstract
Acquired hemophilia A (AHA) is a rare antibody-mediated condition in which autoantibodies form against a coagulation factor, most commonly factor VIII (FVIII), causing severe coagulopathy. Here the present report presents a case of AHA in a 35-year-old postpartum woman with continuous polyserous bloody effusions who was admitted to the First Affiliated Hospital of Zhejiang Chinese Medical University (Hangzhou, China) in October 2017 without a history of trauma, anticoagulation treatment or coagulopathy. At presentation, the patient's hemoglobin level was low (70 g/l; normal range: 115–150 g/l) g/l, blood pressure was 89/58 mmHg (normal range, 90–140/60–90 mmHg), and activated partial thromboplastin time was 68.4 sec (normal range: 25.0–36.0 sec), with a normal international normalized ratio (0.94; normal range, 0.8–1.2). The reaction time in thrombography was prolonged (35.8 min; normal range: 5–10 min), coagulation FVIII had markedly decreased activity (12.6%; normal range, 60–150%), and FVIII inhibitor had a high titer [7.4 Bethesda units (BU)/ml; normal range, 0–0.6 BU/ml]. Notably, the patient's autoantibody level was markedly higher than normal (1:320; normal range: <1:100). The patient was successfully treated with bleeding control, eradication of FVIII inhibitor, and treatment of the underlying disease. To the best of our knowledge, this is the first case of AHA with polyserous bloody effusions in a patient with an autoimmune disorder during the postpartum period. Reports of such rare cases will aid the characterization of disease pathogenesis, which may in turn lead to the recognition and timely treatment of this rare disorder.

Abstract
Acquired hemophilia A poses a clinical and diagnostic challenge. Although rare, it is still the most common acquired factor deficiency. We present a case of acquired hemophilia A diagnosed in a 71-year-old female who presented with a right thigh hematoma of acute onset. The diagnosis was established based on the coagulation profile along with factor VIII levels, mixing studies, and inhibitor levels. The patient received multiple lines of therapy including steroids, factor VIIa, Obizur (porcine-derived recombinant factor VIII), followed by multiple cycles of chemotherapy including cyclophosphamide and rituximab.

Abstract
Acquired hemophilia A (AHA) is an uncommon bleeding disorder infrequently reported among Indians. The present retrospective data comprises eight cases of AHA over a period of 15 years. The mean age of patients was 59.7 years. The activated partial thromboplastin time was prolonged in all cases and the inhibitor screen showed the presence of inhibitors. Factor VIII: C assay was performed in 7 cases and all cases demonstrated low levels. Lupus anticoagulant was negative. Six patients were managed with steroids and symptomatic supportive care. These patients were followed up for a mean period of 3.5 years (range 1-5 years). Of these, there was one fatality prior to initiation of therapy and one patient continues to have inhibitors.

Abstract
BACKGROUND Acquired hemophilia is a rare but potentially dangerous bleeding disorder caused by autoantibodies against coagulation factors. It affects 1 to 1.5 per 1 million people each year. While 50% of cases could be idiopathic, other causes include malignancies, diabetes, pregnancy, infection, and autoimmune disorders. CASE REPORT We report a case of a 90-year-old male who developed a spontaneous hematoma on the dorsum of his right hand, with no prior history of trauma or any other mucosal bleeding. His activated partial thromboplastin time (aPTT) was found to be prolonged (>180 seconds) with a very low level of factor VIII (0.1%). CONCLUSIONS As workups did not identify the source, including malignancy and autoimmune diseases, of his acquired hemophilia, it is believed to be idiopathic. He was started on intravenous recombinant factor VIIa (NovoSeven) to control the bleeding in combination with an immunosuppressive therapy of cyclophosphamide and prednisolone. In approximately 10% of patients with acquired hemophilia, underlying malignancy, such as squamous cell cancer, chronic lymphocytic leukemia, non-Hodgkin lymphoma, and multiple myeloma can present and commonly develop in elderly patients. Therefore, patients diagnosed with idiopathic acquired hemophilia should be given long-term follow up.

Abstract
Acquired von Willebrand syndrome (AVWS) is a rare clinical entity presenting with heterogeneous hemorrhagic manifestations, although some subsets of patients with AVWS may be asymptomatic until they are exposed to major trauma, an invasive procedure, or surgery. We herein report one such case in a 73-year-old male patient with nephrotic syndrome with a prolonged active partial thromboplastin time. We initially did not deal with this distinct abnormal clotting profile seriously, but persistent bleeding after a retroperitoneoscopic-assisted renal biopsy that allowed us to ascribe his nephrotic syndrome to membranous nephropathy fortuitously led to the discovery of concurrent AVWS. We feel that an accurate and prompt diagnosis as well as awareness of the disease remain a challenge for physicians and therefore strongly recommend the further accumulation of experiences similar to our own in a prospective manner. This report underscores the pitfalls associated with determining the bleeding risk, including an insufficient assessment and improper weighting of an abnormal clotting profile prior to the invasive procedure. Several management concerns that emerged in the current case are also discussed.

Abstract
Background Electronic health records (EHRs) can provide insights into diagnoses, treatment patterns, and clinical outcomes. Acquired hemophilia (AH) is an ultrarare bleeding disorder characterized by factor VIII inhibiting autoantibodies. Aim To identify patients with AH using an EHR database. Methods Records were accessed from a large EHR database (Humedica) between January 1, 2007 and July 31, 2013. Broad selection criteria were applied using the International Classification of Diseases, Ninth Revision, clinical modification (ICD-9-CM) code for intrinsic circulating anticoagulants (286.5 and all subcodes) and confirmation of records 6 months before and 12 months after the first diagnosis. Additional selection criteria included mention of “bleeding” within physician notes identified via natural language processing output and a normal prothrombin time and prolonged activated partial thromboplastin time. Results Of 6,348 patients with a diagnosis code of 286.5 or any subcodes, 16 males and 15 females met the selection criteria. The most common bleeding locations reported was gastrointestinal (23%), vaginal (16%), and endocrine (13%). A wide range of comorbidities was reported. Natural language processing identified chart note mention of “hemophilia” in 3 patients (10%), “bruise” in 15 patients (48%), and “pain” in all 31 patients. No patients received a prescription for approved/recommended AH treatments. Four patient cases were reviewed to validate whether the identified cohort had AH; each patient had bleeding symptoms and a normal prothrombin time and prolonged activated partial thromboplastin time, although none received hemostatic treatments. Conclusion In ultrarare disorders, ICD-9-CM coding alone may be insufficient to identify patient cohorts; multimodal analysis combined with in-depth reviews of physician notes may be more effective.

Abstract
Acquired haemophilia is a potentially life-threatening bleeding disorder caused by the development of autoantibodies against coagulation factors, most commonly against factor (F) VIII (acquired haemophilia A; AHA). In around half of patients, an underlying disorder is associated with AHA; the remaining cases are idiopathic. Typically, the disorder presents with bleeding, ranging from mild to life- and limb-threatening, in patients with no personal or family bleeding history. Diagnosis involves an isolated prolongation of the activated partial thromboplastin time, without correction in mixing studies, low FVIII activity levels and evidence of a FVIII inhibitor. As AHA is rare, a lack of familiarity of the condition may result in delayed diagnosis, and prompt haemostatic control is required to reduce morbidity and mortality. Bypassing agents (recombinant activated factor VII or activated prothrombin complex concentrates) can be used to control acute bleeding, and immunosuppression is necessary to eradicate the inhibitor. As clinical trials in this rare and heterogeneous disease are difficult, current evidence comes from observational studies, including registries. This review will focus on the diagnostic and therapeutic challenges of AHA and summarise how understanding of this complex condition has increased based on recent registry data.

Abstract
BACKGROUND Acquired haemophilia A is a rare bleeding disorder caused by the development of specific autoantibodies against coagulation factor VIII. Rituximab may be an alternative approach to the treatment of acquired haemophilia by eradicating FVIII autoantibodies. OBJECTIVES To assess and summarise the efficacy and adverse effects of rituximab for treating people with acquired haemophilia A. SEARCH METHODS We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's trials registers, comprising references identified from comprehensive electronic database searches and handsearches of relevant journals and conference proceedings.Date of last search of the Cochrane Cystic Fibrosis and Genetic Disorders Group's trials registers: 01 March 2016. SELECTION CRITERIA Randomised and quasi-randomised controlled trials of rituximab for people with acquired hemophilia A, with no restrictions on gender, age or ethnicity. DATA COLLECTION AND ANALYSIS No trials matching the selection criteria were eligible for inclusion. MAIN RESULTS No trials matching the selection criteria were eligible for inclusion. AUTHORS' CONCLUSIONS No randomised clinical trials of rituximab for acquired hemophilia A were found. Thus, based on the highest quality of evidence, we are not able to draw any conclusions or make any recommendations on rituximab for eradicating inhibitors in people with acquired haemophilia A. Given that undertaking randomised controlled trials in this field is a complex task, the authors suggest that, while planning such trials, clinicians treating the disease continue to base their choices on alternative, lower quality sources of evidence. The authors plan, for a future update of this review, to appraise and incorporate any randomised controlled trials, as well as other high-quality non-randomised studies.

Abstract
Background: Malignancy-associated bleeding can pose diagnostic dilemmas. We report a unique case of paraneoplastic acquired hemophilia A (AHA), immune thrombocytopenia (ITP), and immune neutropenia in a patient with pancreatic adenocarcinoma. Case Presentation: A 66-year-old male with newly diagnosed pancreatic cancer and normal preoperative hematological evaluation was taken to the operating room for pancreaticoduodenectomy. The operation was aborted due to empyema of the gall bladder, cholangitis, and local extent of disease. Postoperatively, the patient developed bleeding diatheses with mucocutaneous and intra-abdominal bleeding and a prolonged activated partial thromboplastin time. Evaluation revealed high-titer factor VIII inhibitor confirming AHA. Management with bypassing agents such as recombinant activated factor VII, factor VIII inhibitor bypassing activity, and immunosuppression with steroids, cyclophosphamide, and rituximab achieved remission in 2 months. ITP developed after achieving normal factor VIII levels, which was managed with intravenous immunoglobulin. Neutropenia was detected before initiation of chemotherapy and was managed with granulocyte-colony stimulating factor. Conclusion: These unique challenges posed by paraneoplastic hematological syndromes warrant the need for astute clinical judgment and multidisciplinary collaboration for effective management.
