Treatment with fostamatinib in patients with immune thrombocytopenia: Experience from the Andalusian region in Spain-The Fostasur Study.

Immune thrombocytopenia (ITP) is characterized by low platelet counts (PLTs) and an increased risk of bleeding. Fostamatinib, a spleen tyrosine kinase inhibitor, has been approved as a second-line treatment for ITP. Real-world data on fostamatinib are lacking. This observational, retrospective, multicentre study, conducted in the Andalusia region of Spain, evaluated 44 adult primary ITP patients (47.7% female; median age 58 years; newly diagnosed ITP 6.8%; persistent 13.6%; chronic 79.5%; median four prior treatments) after ≥ 4 weeks of fostamatinib therapy. The median PLT at the initiation of fostamatinib was 15 × 109/L. Common reasons for starting fostamatinib were refractoriness or intolerance to prior therapy, oral medication preference, history of thrombosis and cardiovascular risk. Dosing was individualized based on efficacy and tolerance. After 2 weeks, global response rate was 56.8% (response and complete response). Response rates were 70.5%, 62.5% and 64% at 4 weeks, 12 weeks and at the end of the study respectively. Adverse events were mild, and no patients discontinued as a result. This real-world study demonstrated a response rate similar to fostamatinib as seen in the pivotal clinical trials while including newly diagnosed patients and allowing for individualized dosing.

Management of Urgent Bleeding in Patients with Hemophilia A: Focus on the Use of Emicizumab.

Management of patients with hemophilia A (HA) requires the knowledge and experience of specialized health care professionals. However, these patients may need to be attended in emergencies, outside the referral hospital, where health care professionals do not know about hemophilia and/or new innovative treatments. This study aimed to develop a simple and practical algorithm that could be used in emergency situations by nonspecialized treaters in HA and bleeding with or without factor VIII (FVIII) inhibitors under emicizumab prophylaxis. A group of experts agreed on a simple algorithm, easy to operate, adapted from previous international guidelines, and based on their clinical experience. The proposed algorithm starts with identifying the patient, confirming the diagnosis of HA, prophylaxis with emicizumab, and/or use of other treatments. After stabilizing the patient and stratifying the bleeding risk, the patient is managed according to the presence/absence of FVIII inhibitors. Patients without FVIII inhibitors should receive FVIII concentrate. Dose and follow-up depend on bleeding localization and severity. Patients with FVIII inhibitors should preferably receive recombinant activated factor VII as bypass agent. A basic coagulation assay, FVIII assessment, and FVIII inhibitors detection assays are necessary in an emergency. However, these tests should be interpreted with caution and appropriately chosen, as emicizumab may alter the results. The management of patients with HA is challenging in emergency situations, especially if they are treated with new agents. Nonspecialized in coagulopathies health care professionals have limited understanding of the disease, highlighting the need for an algorithm to assist them in making informed decisions.

2-years retrospective observational case-control study on survival and marginal bone loss of implants in patients with hereditary coagulopathies

Background: Evaluating 2-years implant loss and marginal bone loss in patients with hereditary coagulopathies, comparing with a healthy control group. Material and Methods: 37 implants in 13 patients (17 haemophilia A, 20 Von-Willebrand disease) versus 26 implants in 13 healthy patients. Data measured through Lagervall-Jansson index (after surgery, at prosthetic loading, at 2 years). Statistics: Chi-square, Haberman’s, ANOVA, Mann-Whitney-U. Significance p<0.05. Results: Haemorrhagic accidents in 2 coagulopathies patients (non-statistical differences). Hereditary coagulopathies patients suffered more hepatitis (p<0.05), HIV (p<0.05) and less previous periodontitis (p<0.01). Non-statistical differences in marginal bone loss among groups. 2 implants were lost in the hereditary coagulopathies and none in the control group (non-statistical differences). Hereditary coagulopathies patients had longer (p<0.001), and narrower implants (p<0.05) placed. 43.2% external prosthetic connection in hereditary coagulopathies patients (p<0.001); change of prosthetic platform more frequent in control group (p<0.05). 2 implants lost: external connection (p<0.05). Survival rate 96.8% (hereditary coagulopathies 94.6%, control group 100%). Conclusions: Implant and marginal bone loss at 2 years is similar in patients with hereditary coagulopathies and control group. Precautions should be taken on the treatment for hereditary coagulopathies patients, through prior haematological protocol. Implant loss only occurred in in a patient with Von-Willebrand´s disease.

Acquired Haemophilia A: A Review of What We Know.

Autoantibodies against plasma coagulation factors could be developed by some individuals inducing severe and sometimes fatal bleedings. This clinical entity is called acquired haemophilia. It should be suspected in subjects with acute abnormal bleedings, without personal or familiar history of congenital bleeding disorders with an unexplained prolonged aPTT. It is rare disease, although its incidence may be underestimated due to the low knowledge about it by many specialists, the frequent use of anticoagulant or antiplatelet therapies in the affected population that can mask the diagnosis and, sometimes, a so withering effect that avoid its confirmation. Mortality ranges between 9% and 33% depending on the series in the first 2 months after diagnosis. This mortality is attributed in up to 40% of the cases to infections in the context of immunosuppressive treatments used to eliminate the inhibitor. Factor VIII levels below 1% and high inhibitor titers are conditions of worse response rates. Advanced age, patient's ECOG, and underlying conditions are key prognostic factors for response to treatment and patient survival. To reduce morbidity and mortality in these patients, it is important to have clinical knowledge and access to guidelines to achieve an early diagnosis and to optimize the haemostatic and immunosuppressive treatment. This review aims to contribute to the dissemination of basic concepts on the epidemiology etiopathogenesis, diagnosis, treatment and management of these patients, as well as risk factors to get remission and the longest overall survival to allow individualized care. Especial awareness will be proposed in patients with some underlying conditions like cancer, autoimmune diseases, children, pregnancy or drugs.

Genotype/phenotype relationship in Gaucher disease patients. Novel mutation in glucocerebrosidase gene.

Objectives Gaucher disease (GD) is the most common inherited lysosomal storage disease, caused by mutations in acid ß-glucosidase (GBA) gene. This study aimed to identify mutations in Andalusia patients with GD and their genotype-phenotype correlation. Methods Descriptive observational study. University Hospital Virgen del Rocio patients diagnosed from GD from 1999 to 2019 were included. Demographic and clinical data, ß-glucocerebrosidase activity, variants pathogenic in GBA gene and biomarkers for monitoring treatment were collected from digital medical record. Results Twenty-six patients with aged between 1 day and 52 years were studied. A total of six mutations described as pathogenic and one mutation not described above [c.937T>C (p.Tyr313His)] were identified in the GBA gene, four patients were homozygotes and 22 compound heterozygotes. Twenty-four patients were diagnosed in non-neuropathic form (type 1) and two cases presented neurological involvement (type 2 or 3). The most common variant was c.1226A>G (p.Asn409Ser), which was detected in 24 patients, followed by c.1448T>C (p.Leu483Pro) variant, identified in 13 patients. The c.1448T>C (p.Leu483Pro) mutation has been presented in the most severe phenotypes with neurological involvement associated with type 2 and 3 GD, while c.1226A>G (p.Asn409Ser) mutation has not been associated with neurological alterations. Splenomegaly and bone disease were the most frequent clinical manifestations, and thrombocytopenia was the most common hematological disorder. Conclusions The c.1226A>G (p.Asn409Ser) and c.1448T>C (p.Leu483Pro) mutations were the most common. The c.937T>C (p.Tyr313His) was identified as a novel mutation. The c.1448T>C (p.Leu483Pro) mutation was associated with neurological alterations and c.1226A>G (p.Asn409Ser) mutation has not been associated it.

Catepsina K como biomarcador de afectación ósea en la enfermedad de Gaucher tipo 1 / Cathepsin K as a biomarker of bone involvement in type 1 Gaucher disease

Fundamento y objetivo: La enfermedad de Gaucher es un trastorno hereditario, que se origina como consecuencia del déficit de la actividad β-glucocerebrosidasa ácida, responsable de la degradación de glucosilceramida hasta ceramida y glucosa. Aunque el trastorno de base es fundamentalmente hematológico, el hueso es la segunda estructura más frecuentemente afectada. La catepsina K (CATK) es una enzima implicada en el proceso de remodelado óseo, habiéndose propuesto que la determinación de sus concentraciones séricas podría aportar información complementaria a la de otros biomarcadores. Pacientes y métodos: Se realizó un estudio en 20 controles sanos y 20 pacientes con enfermedad de Gaucher tipo 1, de las comunidades autónomas de Andalucía y Extremadura. Se determinaron como biomarcadores de remodelado óseo la bone alkaline phosphatase (B-ALP, «fosfatasa alcalina ósea»), el amino-terminal propeptide of procollagen type 1 (P1NP, «propéptido aminoterminal del procolágeno 1»), la β-Cross Laps, carboxy-terminal telopeptide of collagen type 1 (CTx, «fracción β del colágeno tipo 1») y CATK por técnicas de electroquimioluminiscencia y enzimoinmunoanálisis. Resultados: Existe un incremento en los niveles de CATK y las ratios CATK/P1NP y CATK/B-ALP en los pacientes con Gaucher tipo 1 respecto a la media obtenida en el grupo control. Por otro lado, considerando la existencia o no de manifestaciones óseas en el grupo de pacientes, la CATK y la ratio CATK/P1NP muestran niveles medios superiores en aquellos pacientes con daño óseo respecto a los que no lo presentan. Conclusiones: Aunque los estudios radiológicos constituyen el gold-standard para el seguimiento de enfermedad ósea en pacientes con enfermedad de Gaucher tipo 1, debe considerarse la utilidad de la CATK como posible indicador de daño óseo en estos pacientes. Asimismo, este parámetro puede utilizarse en la monitorización del tratamiento de la enfermedad ósea (AU)

Background and objective: Gaucher disease is an inherited disorder caused by deficit of acid β-glucocerebrosidase, responsible for the degradation of glucosylceramide to ceramide and glucose. Although the disorder is primarily hematologic, bone is the second most commonly affected structure. Cathepsin K (CATK) is an enzyme involved in bone remodelling process. It has been proposed that determination of its serum concentrations may provide additional information to other biomarkers. Patients and methods: The study included 20 control subjects and 20 Gaucher type 1 patients from Andalusia and Extremadura regions. We analyzed the biomarkers of bone remodelling: the bone alkaline phosphatase (B-ALP), the N-terminal propeptide of type 1 procollagen (P1NP), the β carboxyterminal telopeptide of type 1 collagen (CTx) and the CATK through electrochemiluminescence and immunoassay techniques. Results: There is an increase in levels of CATK, CATK/P1NP and CATK/B-ALP ratios in type 1 Gaucher patients compared to the control group. Considering the existence of skeletal manifestations in the patient group, the CATK and CATK/P1NP ratio showed higher levels in patients with bone damage compared to those without it. Conclusions: Although imaging studies are the gold standard for monitoring bone disease in type 1 Gaucher patients, the utility of CATK should be considered as a possible indicator of bone damage in these patients. Furthermore, this parameter can be used in the monitoring of the treatment of bone pathology (AU)

Protocol for oral implant rehabilitation in a hemophilic HIV-positive patient with type C hepatitis.

CASE REPORT: A 46-year-old man with severe hemophilia A, stage A2 HIV infection and chronic hepatitis C genotype 1A, for whom the treatment plan included implant-supported prostheses in 2 mandibular edentulous sections. The protocol followed included factor VIII replacement concentrate and oral antifibrinolytic therapy. The right mandibular section was fitted with 3 Straumann implants (Ø 4.1 mm, length 10 mm), and the left mandibular section received 2 implants of the same characteristics. The patient showed no postoperative complications. After implant placement, the patient attended scheduled review appointments. After a 3-month period of osseointegration, the prosthesis was fitted. CONCLUSIONS: Although, in this case, the treatment proved successful 2 years postrehabilitation and the protocol used seems safe and effective, long-term prospective studies are needed to evaluate the implant success rate in these patients.
