Lupus anticoagulant hypoprothrombinemia syndrome (LAHPS) comprises lupus anticoagulant, acquired hypoprothrombinemia, and often mild thrombocytopenia or normal platelets. It is usually associated with autoimmunity or postviral illness. We describe a case of a 10-year-old boy with oral bleeding and severe thrombocytopenia initially suggestive of immune thrombocytopenia. Secondary to bleeding, evaluation demonstrated prolonged coagulation tests and subsequently revealed the presence of lupus anticoagulant and hypoprothrombinemia, along with marked autoimmunity, suggestive of LAHPS...

The lupus anticoagulant-hypoprothrombinemia syndrome (LA-HPS) - the association of acquired factor II deficiency and lupus anticoagulant - is a rare disease that may cause a predisposition not only to thrombosis but also to severe bleeding. We are reporting on a 36-year-old female patient presenting with co-existing cerebral venous thrombosis and subdural hemorrhage. The coagulation screening showed a prolonged prothrombin time (PT), activated partial thromboplastin time (aPTT), and a normal fibrinogen level and platelet count...

OBJECTIVES: The main clinical sequela of a lupus anticoagulant is increased thrombosis risk. However, bleeding due to lupus anticoagulant-hypoprothrombinemia syndrome is a rare but well-described manifestation of antiphospholipid syndrome. The association of acute acquired hypoprothrombinemia is caused by a lupus anticoagulant's specificity to prothrombin, which results in clearance of prothrombin and bleeding due to hypoprothrombinemia (usually <10% of normal). Severe life-threatening bleeding is most frequently reported in children with systemic lupus erythematosus or in healthy children after viral infection...

Lupus anticoagulant-hypoprothrombinemia syndrome is a rare condition characterized by the association of acquired factor II deficiency and lupus anticoagulant. Contrary to classical antiphospholipid syndrome, it may cause severe life-threatening bleeding (89% of published cases). We report a patient, positive for antidomain I antibodies, with initially primary lupus anticoagulant-hypoprothrombinemia syndrome without previous clinical manifestation or underlying systemic disease. Five years later, he experienced the first systemic lupus erythematous flare...

Antiphospholipid syndrome (APS), an acquired thrombotic condition, is a complex clinical state characterized by the presence of circulating antiphospholipid antibodies in patients with thrombosis or pregnancy morbidity. Revised APS classification criteria are used for diagnosis, which include at least one clinical criterion (thrombosis or pregnancy loss) and at least one of the laboratory criteria [anticardiolipin antibodies, anti-β2GPI antibodies, lupus anticoagulant (LA)]. LA is also an independent risk factor for developing thrombosis, though some LA-positive cases have been reported to have a bleeding symptom...

INTRODUCTION: Lupus anticoagulant associated with acquired prothrombin deficiency also known as 'lupus anticoagulant hypoprothrombinemia syndrome' (LAHS) is an entity that is well described in adults and is usually associated with autoimmune conditions (LAHS-AI). However, in children, LAHS has unique features that are distinct from the adult type. AIMS: We report two paediatric cases of LAHS, describe their distinct patterns and review the paediatric literature on LAHS...

Antiphospholipid antibody-positive patients can develop bleeding due to capillaritis, microthrombosis, antiprothrombin antibodies, thrombocytopenia, and/or excessive antithrombotic therapy. Clinical characteristics of patients, e.g., renal impairment, elderly, or concomitant medications, are closely related to the risk of bleeding. The management of bleeding in antiphospholipid antibody (aPL)-positive patients is challenging due to the baseline increased risk of thrombosis. If anticoagulation is stopped, it should be restarted as soon as possible once the acute bleeding is controlled; the continuation of anticoagulation despite active bleeding may be required in selected cases...

Lupus anticoagulant-hypoprothrombinemia syndrome (LA-HPS) is a rare acquired disorder caused by prothrombin antibodies. The disease is most common in the pediatric age group (<16 years), and more prevalent in women. There are well-established clinical diseases associated with LA-HPS, most notably systemic lupus erythematosus (SLE) and viral infections. The clinical manifestation of LA-HPS varies greatly in severity and it may cause severe life-threatening bleeding diathesis. LA-HPS is to be suspected when a patient presents with bleeding and a prolonged activated partial thromboplastin and prothrombin time, in combination with a lupus anticoagulant...

Lupus anticoagulant-hypoprothrombinemia syndrome (LAHPS), a very rare disease that is caused by the presence of antifactor II antibodies, is usually counterbalanced by the prothrombotic effect of lupus anticoagulant (LAC). Patients with LAHPS are treated using fresh frozen plasma, steroids, immunosuppressive agents, and immunoglobulins for managing the disease and controlling hemorrhages. Notably, steroids are the important treatment for treating hypoprothrombinemia and controlling the bleeding. However, some patients suffer from severe, life-threatening hemorrhages, when factor II levels remain very low in spite of treatment with steroids...

We describe a previously healthy 9-year-old girl who had multiple purpura several days after acute adenovirus gastroenteritis and mycoplasma pneumonia. Initial laboratory evaluation revealed a prolonged prothrombin time (PT) and APTT, low complement levels (C4, CH50), and positive immune complex (C1q) in her serum. Platelet count, fibrinogen, and other routine blood chemistry tests were normal. The prolonged APTT was not corrected by mixture of the patient's plus normal plasma. Clotting activities of factors II, V, VIII, IX, X, XI, and XII reduced...

Acquired inhibitors of coagulation causing bleeding manifestations are rare in children. They emerge, normally in the context of autoimmune diseases or drug ingestion, but transient and self-limiting cases can occur after viral infection. We describe, an otherwise healthy, 7-year-old girl who had gingival bleeding after a tooth extraction. The prothrombin time (PT) and the activated partial thromboplastin time (APTT) were both prolonged with evidence of an immediate acting inhibitor (lupic anticoagulant). Further coagulation studies demonstrated prothrombin (FII) deficiency and prothrombin directed (FII) antibodies...

Hypoprothrombinemia associated with a lupus anticoagulant (LA) was first reported in the literature over 50 years ago. The hypoprothrombinemia-lupus anticoagulant syndrome (HLAS) is a rare bleeding diathesis that has been associated with LAs in adult and paediatric patients with systemic lupus erythematosus (SLE) and with transient LAs due to other causes. There are no standard recommendations for treating haemorrhage associated with this syndrome. Herein, we report a patient with SLE and HLAS who achieved a durable remission following treatment with intravenous immune globulin (IVIG), prednisone and rituximab...

We report a case of a 1-year-old boy diagnosed with lupus anticoagulant-hypoprothrombinemia syndrome (LA-HPS), which is a rare disorder. His initial presentation of sinusitis was accompanied by hemorrhagic episodes including ecchymoses and epistaxis 6 months after antibiotic therapy. Laboratory results revealed prolonged prothrombin time (PT) and activated partial thromboplastin time (APTT) that did not correct with mixing studies. Factors II, VIII, IX, X, XI, and XII activities were 20%, 44%, 42.5%, 59%, 4%, and 10%, respectively...

The lupus anticoagulant-hypoprothrombinemia syndrome (LAHS)--the association of acquired factor II deficiency and lupus anticoagulant--is a rare disease drastically different from antiphospholipid syndrome in that it may cause predisposition not only to thrombosis but also to severe bleeding. We performed a retrospective study of 8 patients with LAHS referred to 6 French tertiary care centers between January 2003 and February 2011, and a literature review retrieving all related articles published between 1960 and April 2011...

Diagnosis criteria, pathogenic mechanisms, incidence and prevalence of the Antiphospholipid Syndrome are focused in a brief review. Hypoprothrombinemia (HPT) may be hereditary or acquired; the first is rare and with recessive autossomic transmission. We report the case of a 66-year-old white woman with Systemic Lupus Erythematosus (SLE), autoimmune haemolytic anaemia, periostitis, haematomas, bleeding leg ulcer and rectal haemorrhages; she had decreased levels of the prothrombin. Haemorrhagic episodes were related with the anti-prothrombin specificity of Lupus Anticoagulant (LA) detected...

UNLABELLED: We describe two children with significant bleeding: one with multiple ecchymoses and the other with scrotal bleeding. In both patients, the activated partial thromboplastin time (APTT) was prolonged, with positivity for lupus anticoagulants (LA). However, the Owren prothrombin time (PT), usually insensitive for LA, was also prolonged. The presence of LA is associated with diverse clinical manifestations, with most patients being asymptomatic while others present venous or arterial thrombosis...
