RESUMEN

AIM: Many women with inherited bleeding disorders are not diagnosed because of a lack of appropriate indicators. This study aimed to assess the predictability of the pictorial blood loss assessment chart (PBAC) as an indicator of menorrhagia and identify an easy indicator of menorrhagia resulting from bleeding disorders. METHODS: A multicenter study enrolled 9 patients with von Willebrand disease (VWD), 23 hemophilia carriers, and 71 controls aged 20-45 years who completed PBACs for two menstrual cycles as well as questionnaires. RESULTS: The PBAC scores of the VWD were significantly higher than those of other groups, even in multivariate analysis with age and sanitary item factors (p = 0.014). A PBAC score of 100 was not an appropriate cutoff because of its low specificity (VWD: sensitivity, 100; specificity, 29.5; hemophilia carriers: 74 and 29.5, respectively). In the ROC analysis, the cutoff of optimal PBAC for VWD was 171 (sensitivity, 66.7; specificity, 72.3; AUC, 0.7296). As the pad length increased, the total length of the pads used during one menstrual period could be a new and easy indicator. However, the cutoff for VWD was 735 cm (sensitivity, 42.9; specificity, 94.3; AUC 0.6837). A threshold could not be established for the hemophilia carrier. Therefore, we multiplied the coefficient by the length of thick pads, which caused a lower PBAC. For the VWD, the sensitivity increased to 85.7 (specificity, 77.1). For the hemophilia carrier, sensitivity (66.7) and specificity (88.6) could be separated from the control. CONCLUSIONS: The total length of the pads with a thick-pad adjustment can be a simple method to identify bleeding disorders.

RESUMEN

Catastrophic antiphospholipid syndrome (CAPS) is a severe variant of antiphospholipid syndrome associated with multiorgan thrombosis in a short term. We present the case of a 14-year-old immunocompetent girl who developed renal, intestinal, and pulmonary infarction; thrombocytopenia; and hemolytic anemia within 1 week. She was diagnosed with thrombotic microangiopathy. Hence, plasma exchange and corticosteroid therapy were initiated, which improved thrombocytopenia. However, the patient's platelet count decreased. Her general condition gradually worsened with eventual death. An autopsy revealed multiple infarctions in the kidneys bilaterally, jejunum, ileum, and pulmonary parenchyma. Microthrombi were not detected. Massive hemophagocytosis was observed in the splenic pulp, lymph nodes, and bone marrow. Several Epstein-Barr viruses (EBVs)-encoded small ribonucleic acid (RNA)-positive lymphocytes were also found in the bone marrow. The presence of antibodies to both viral capsid antigen-immunoglobulin G and EBV nuclear antigen indicated past infection. Antiphospholipid antibody was positive after her death. The patient was finally diagnosed with CAPS and EBV-associated hemophagocytosis, possibly due to EBV reactivation. Establishing a clinical diagnosis of CAPS was relatively difficult because two different causes of thrombocytopenia, CAPS and hemophagocytosis, led to a difficulty in understanding this case's pathogenesis.

RESUMEN

A 14-year-old inhibitor-positive male patient with severe hemophilia A and severe psychomotor disability was admitted due to left buccal swelling and impaired downward movement of the left eye. He had been on noninvasive positive-pressure ventilation (NPPV) through a nasal mask for upper airway obstruction. The patient began to have repeated epistaxis 16 months after initiation of treatment with 6 mg/kg Q4W of emicizumab, and was thus administered a bypassing agent. Left buccal swelling and impaired downward movement of the left eye appeared during the subsequent month. Imaging examination revealed a mass in the left maxillary sinus and bone destruction. Endoscopic tumor resection and tracheostomy were performed using recombinant activated factor VII. NPPV was discontinued thereafter. Pathological examination revealed that the mass was a hemophilic pseudotumor (HP). After discharge the emicizumab-regimen dose was changed to 3 mg/kg, Q2W to increase serum emicizumab levels. No recurrent HP or bleeding requiring treatment was observed. Pressure applied to the damaged nasal mucosa by NPPV was suspected as the main cause of HP development. If a mass is observed in a patient with hemophilia, HP should be considered as a possible diagnosis even if the patient is receiving emicizumab.

RESUMEN

Acquired hemophilia A (AHA) is a disease that causes severe bleeding with the appearance of an inhibitor (INH) against blood coagulation factor VIII (FVIII). The prevalence of this condition is low; it occurs in only one in one to four million people per year; however, the number of diagnosed cases has increased in recent years owing to the greater awareness of the disease. It is noteworthy that this is a hemorrhagic disease that suddenly develops in the elderly. AHA treatment is divided into hemostatic treatment for bleeding and immunosuppressive therapy (IST) for removing FVIII-INH. As long as FVIII-INH remains, there is a risk of fatal bleeding; therefore, it is desirable to start IST soon after diagnosis. However, the use of immunosuppressive drugs for the elderly is often challenging due to concerns about adverse events, such as infectious diseases that have a considerable impact on prognosis. Ten years after the end of IST, we managed the case of a patient with AHA who had a relapse of FVIII-INH at the age of 84 years. In this case, relapse was detected early when there was no bleeding symptom, and remission was rapidly achieved with a small amount of IST without any adverse effects. There are few reports on AHA relapse; we believe that the present report will contribute meaningfully to the literature on this subject and would be useful when considering the long-term management of AHA.

RESUMEN

: The novel agent pd-FVIIa/FX is a 1 : 10 protein weight mixture of activated factor VII (FVIIa) and factor X (FX) derived from donated blood plasma. A phase III clinical trial of pd-FVIIa/FX revealed high efficacy for bleeding episodes in haemophilia patients with inhibitors. However, up to now, only one case of this new agent being used for surgery had been reported. The objective of this study is to evaluate the perioperative haemostatic efficacy and safety of pd-FVIIa/FX in haemophilia patients with inhibitors. We retrospectively reviewed 25 operation charts from 14 haemophilia patients with high-responding inhibitors using pd-FVIIa/FX during the perioperative period. Efficacy was evaluated by attending physicians and results divided into four groups (excellent, good, fair, and poor). The operation chart was provided by nine Japanese medical institutes with expertise in haemophilia management. Out of the total of 25 surgical procedures, 44% (11/25) were classified as major surgery and the remainders were minor surgeries. In all of the surgeries but one, rFVIIa and/or APCC were administered in combination or sequential method. In all cases except one, the haemostatic efficiency rate was judged as excellent or good by treating physicians for an overall efficacy rate of 96%. No thrombotic adverse effects were reported. This study's results suggest that both combination and sequential therapy of pd-FVIIa/FX and other bypassing agents are well tolerated and effective for the control of perioperative bleeding in haemophilia patients with high-responding inhibitors.

RESUMEN

Acquired hemophilia A (AHA), a bleeding disorder caused by autoantibodies against FVIII, has the potential for life-threatening bleeding. The annual onset rate is said to be one in 4 million people, but diagnosis examples increase in adults because a disorder concept penetrated. AHA is quite rare in children, with an incidence rate of 0.045 per 1 million, but early detection is crucial because serious bleeding can happen, as in adults. We report a pediatric case who received an early diagnosis of AHA by an activated partial thromboplastin time (APTT) cross-mixing test. The 12-year-old girl had neither a past history nor a family history of bleeding episodes. She presented with intramuscular bleeding and epistaxis without trauma or medication. At diagnosis, her blood test showed prolonged APTT. Other hemostatic tests, such as the platelet count, prothrombin time and fibrinogen concentration, were within the normal range. We administered an APTT cross-mixing test that detected an inhibitor pattern and inhibitory antibodies against factors VIII. As a result, we administered prednisolone and the inhibitor disappeared after 1.5 months. In conclusion, AHA is a bleeding disorder which should be considered even in children due to the potential for life-threatening bleeding. Furthermore, the APTT cross-mixing test is useful for screening coagulation factor deficiencies and inhibitors.

RESUMEN

In adults, meningiomas occasionally display aggressive behavior and may occasionally metastasize. By contrast, pediatric meningiomas are rare, and there is limited information regarding their clinical characteristics, treatment and prognosis. We herein report the case of a 3-year-old boy with anaplastic meningioma with a history of local recurrence and late pulmonary metastasis. At diagnosis, a 70-mm mass lesion in was identified in the right frontal lobe, with intratumoral hemorrhage. The tumor was attached to the falx cerebri and was completely resected. The histological diagnosis was anaplastic meningioma, World Health Organization grade III. Two months after the surgery, the meningioma recurred at the same site. Although the patient received radiotherapy after a second operation, the tumor metastasized to the lung and pleura 8 months after the initial operation. The metastasis was resistant to treatment, even after gross total resection, and the effectiveness of further radiotherapy was limited. The patient succumbed to the disease 1 year and 4 months after the initial diagnosis. The findings of the present case and a review of the relevant literature suggest that recurrence and metastasis of meningiomas are difficult to predict. Therefore, such patients should be carefully monitored throughout the follow-up period.
