Hematol Rep 2024; 16:185-192. [PMID: 38651448 PMCID: PMC11036256 DOI: 10.3390/hematolrep16020019] [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: 01/09/2024] [Revised: 03/09/2024] [Accepted: 03/22/2024] [Indexed: 04/25/2024] Open
Abstract
We report a patient with hemophilia A who underwent partial splenic embolization (PSE) for severe thrombocytopenia secondary to portal hypertension-induced splenomegaly, resulting in a stable long-term quality of life. The patient was diagnosed with hemophilia A and unfortunately contracted human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) from blood products. He subsequently developed progressive splenomegaly due to portal hypertension from chronic HCV, resulting in severe thrombocytopenia. PSE was performed because he had occasional subcutaneous bleeding and needed to start interferon (IFN) and ribavirin (RBV) treatment for curing his HCV infection at that time. His platelet counts increased, and no serious adverse events were observed. Currently, he continues to receive outpatient treatment, regular factor VIII (FVIII) replacement therapy for hemophilia A, and antiretroviral therapy for HIV infection. Vascular embolization has been reported to be an effective and minimally invasive treatment for bleeding in hemophilia patients. PSE also provided him with a stable quality of life without the side effects of serious infections and thrombocytopenia relapses. We conclude that PSE is a promising therapeutic option for patients with hemophilia A.

Endovascular Management of Hemarthrosis in Patients with Bleeding Diatheses: Systematic Review. Cardiovasc Intervent Radiol 2019; 43:362-368. [PMID: 31690982 DOI: 10.1007/s00270-019-02367-7] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2019] [Accepted: 10/23/2019] [Indexed: 02/08/2023]
Abstract
PURPOSE In this systematic review, we report the safety and efficacy of embolization for treating hemarthrosis in patients with bleeding diatheses with or without a history of prior arthroplasty. MATERIALS AND METHODS A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. A structured search was performed in PubMed, Web of Science, MEDLINE, and SCOPUS databases of patients undergoing embolization for hemarthrosis. Demographic data, clinical history, angiographic findings, interventions, and outcomes were extracted and tabulated. RESULTS The search identified 97 unique titles of which 15 were deemed relevant comprising 78 patients with coagulopathies undergoing 93 embolization procedures. Mean follow-up time was 29 months (range 3-116.5). In the 29 patients who underwent arthroplasty prior to embolization for hemarthrosis, there were 11 bleeding recurrences (37.9%). Of these patients who experienced recurrences, 10 underwent repeat embolization as coagulation factor replacement was not sufficient to address the re-bleeding. In the 49 patients with bleeding diatheses who underwent embolization for hemarthrosis with no history of prior arthroplasty, there were 11 recurrences (22.4%) and 4 of these patients underwent repeat embolization with favorable results. There were four major procedure-related complications. CONCLUSION Transarterial embolization is safe and effective in addressing recurrent hemarthrosis in patients with bleeding diatheses with or without a history of arthroplasty of the affected joint.

TAFI deficiency causes maladaptive vascular remodeling after hemophilic joint bleeding. JCI Insight 2019; 4:128379. [PMID: 31465300 PMCID: PMC6795396 DOI: 10.1172/jci.insight.128379] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2019] [Accepted: 08/23/2019] [Indexed: 12/23/2022] Open
Abstract
Excessive vascular remodeling is characteristic of hemophilic arthropathy (HA) and may contribute to joint bleeding and the progression of HA. Mechanisms for pathological vascular remodeling after hemophilic joint bleeding are unknown. In hemophilia, activation of thrombin-activatable fibrinolysis inhibitor (TAFI) is impaired, which contributes to joint bleeding and may also underlie the aberrant vascular remodeling. Here, hemophilia A (factor VIII-deficient; FVIII-deficient) mice or TAFI-deficient mice with transient (antibody-induced) hemophilia A were used to determine the role of FVIII and TAFI in vascular remodeling after joint bleeding. Excessive vascular remodeling and vessel enlargement persisted in FVIII-deficient and TAFI-deficient mice, but not in transient hemophilia WT mice, after similar joint bleeding. TAFI-overexpression in FVIII-deficient mice prevented abnormal vessel enlargement and vascular leakage. Age-related vascular changes were observed with FVIII or TAFI deficiency and correlated positively with bleeding severity after injury, supporting increased vascularity as a major contributor to joint bleeding. Antibody-mediated inhibition of uPA also prevented abnormal vascular remodeling, suggesting that TAFI's protective effects include inhibition of uPA-mediated plasminogen activation. In conclusion, the functional TAFI deficiency in hemophilia drives maladaptive vascular remodeling in the joints after bleeding. These mechanistic insights allow targeted development of potentially new strategies to normalize vascularity and control rebleeding in HA.
