OBJECTIVE: To assess serum sclerostin levels in relation to severity of arthropathy and bone mineral density (BMD) in children with hemophilic arthropathy. METHODS: This cross-sectional study included 40 male children suffering from Hemophilia A, and 10 matched healthy controls. Assessment of factor VIII deficiency degree, frequency of bleeding, type of treatment, body mass index (BMI), disease severity using the Hemophilia Joint Health Score (HJHS) and lumbar spine (LS) Z score for bone mineral density (BMD) using dual-energy X-ray absorbiometry was done...

Introduction: Preoperative coagulation screening tests in pediatric patients was once routine clinical practice globally and still used as standard practice in some countries before surgical procedures to assess of perioperative bleeding risk. Objective: The study aimed to evaluate unselected routine preoperative coagulation testing in children undergoing elective or invasive surgery to predict abnormal perioperative bleeding. The study also aimed to provide a rational approach of determining bleeding and family history of coagulation disorders as a predictive risk for bleeding...

BACKGROUND: Needles are frequently required for routine medical procedures. Children with severe hemophilia require intensive intravenous (IV) therapy to treat and prevent life-threatening bleeding and undergo hundreds of IV procedures. Fear of needle-related procedures may lead to avoidance of future health care and poor clinical outcomes. Virtual reality (VR) is a promising distraction technique during procedures, but barriers to commercially available VR platforms for pediatric health care purposes have prevented widespread use...

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...

Hemarthroses and muscle bleeds are well-known and well-documented complications in pediatric and young adult hemophilia patients. In contrast, deep bleeds in atypical locations can be a diagnostic challenge, since clinicians and radiologists are often unfamiliar with their clinical and radiological features. Some atypical bleeds, however, can be life-threatening or severely disabling, highlighting the need for prompt, accurate diagnosis. Rare bleeds include central nervous system bleeds (including intracranial and spinal hematomas), urogenital bleeds, intra-abdominal bleeds (mesenteric and gastrointestinal wall hematomas) and pseudo tumors in unusual locations like the sinonasal cavities...

BACKGROUND: Intracranial hemorrhage (ICH) is a life-threatening condition in children. Inherited bleeding disorders (IBD) have high risk of ICH. AIM: This single center study aims to identify the incidence, risk factors, and neurological outcome of ICH in children who suffer from IBD. METHODS: From 2005 to 2017, 241 children with IBDs from Nanfang hospital, Department of Pediatrics, were evaluated. The ICH episodes were identified by medical history, general physical examination, detailed neurological examination, and computed tomographic or magnetic resonance imaging examination...

Newborns with hemophilia are at risk of intracranial hemorrhage, extracranial hemorrhage, and other bleeding complications. The safe delivery of a healthy newborn with hemophilia is a complex process that can begin even before conception, and continues throughout pregnancy, birth, and the newborn period. This process involves the expectant parents and a wide variety of health-care professionals: genetic counselors, obstetricians, neonatologists, pediatricians, radiologists, adult and pediatric hematologists, and nurses with expertise in hemophilia...

Adherence to treatment regimens in growth hormone dysregulations and hemophilia is related to better outcome and fewer complications over time. Subcutaneous growth hormone injection and intravenous blood factor replacement therapies are parenteral treatments with a comparable regimen calling for similar behavioral processes. Although we have lists of possible factors influencing adherence in these conditions, the evidence is scattered. The objective of this study was to systematically review empirical studies linking factors of adherence with measures of adherence...

BACKGROUND: Bone remodeling is a lifelong process due to the balanced activity of osteoclasts (OCs), the bone-reabsorbing cells, and osteoblasts (OBs), and the bone-forming cells. This equilibrium is regulated by numerous cytokines, but it has been largely demonstrated that the RANK/RANKL/osteoprotegerin and Wnt/β-catenin pathways play a key role in the control of osteoclastogenesis and osteoblastogenesis, respectively. The pro-osteoblastogenic activity of the Wnt/β-catenin can be inhibited by sclerostin and Dickkopf-1 (DKK-1)...

The "Joint Outcomes Study" (JOS) demonstrated improved joint outcomes for patients receiving primary prophylaxis versus on-demand therapy. The impact of primary prophylaxis on inpatient health care utilization is not well-defined. To evaluate changes in hospitalization care of children with hemophilia before and after the 2007 JOS publication, this study utilized the Pediatric Health Information System (PHIS) to evaluate admissions for patients with hemophilia A or B (age, 2 to 7) admitted between January 2002 and 2006 (pre-JOS) and January 2010 and 2014 (post-JOS)...

OBJECTIVE: To compare the costs and clinical consequences of treating mild-to-moderate joint bleeds with recombinant activated factor VII (rFVIIa) versus plasma-derived activated prothrombin complex concentrate (pd-aPCC) in pediatric patients with hemophilia A with inhibitors in Mexico. METHODS: A cost-effectiveness model was developed using TreeAge Pro v14.2.2 software (licensed in the USA) and adapted from a previously published model, with adjustments to reflect local clinical practice...

Hemorrhagic shock is a rare, emergent condition that is often fatal in newborns. In this article, we report cases of 3 neonates presenting with acute, life-threatening hemorrhage who were subsequently diagnosed with severe hemophilia (<1% factor VIII). The first infant was tachycardic, pale, and had a precipitous drop in his hemoglobin secondary to a subgaleal hemorrhage. The second patient sustained a splenic rupture, a sequela that has been reported in only 4 other neonatal cases. The last infant presented with tonic-clonic seizures and respiratory distress...

Little is known about the challenging treatment of pediatric patients with hemophilia B and inhibitors due to disease rarity. We describe three patients diagnosed in childhood and followed up to 9 years. All three had allergic reactions to Factor IX, but two were later safely treated for bleeding episodes with activated prothrombin complex concentrates (APCC = FEIBA). The third was given only recombinant activated Factor VIIa. Based on ex vivo thrombin generation analysis, a new alternative treatment of combined bypassing agents was administered for bleeding episodes and several minor surgical procedures with no treatment-associated adverse events or thrombosis...

JUSTIFICATION: Despite having standard principles of management of hemophilia, treatment differs in various countries depending on available resources. Guideline for management of hemophilia in Indian setting is essential. PROCESS: Indian Academy of Pediatrics conducted a consultative meeting on Hemophilia on 18th September, 2016 in New Delhi, which was attended by experts in the field working across India. Scientific literature was reviewed, and guidelines were drafted...

Polyethylene glycol (PEG) is an inert, water soluble polymer, used for decades in pharmaceuticals. Although PEG is considered safe, concerns persist about the potential adverse effects of long-term exposure to PEG-containing therapies, specifically in children, following the introduction of PEGylated recombinant factor products used for the treatment of hemophilia. Given the absence of long-term surveillance data, and to evaluate the potential risk, we estimated PEG exposure in the pediatric population receiving PEGylated therapies with pediatric indications administered intravenously or intramuscularly...

BACKGROUND: Hemophilia is an inherited bleeding disorder. With proper treatment and self-care, persons with hemophilia can maintain an active, productive lifestyle. Hemophilia can be mild, moderate, or severe, depending on the degree of plasma clotting factor deficiency. The aim of the study was to assess the utility of ISTH-BAT in diagnosis, determining severity of the bleeding condition in newly diagnosed and known hemophilia patients, compare the bleeding score (BS) in adult and pediatric groups and investigate its association with plasma factor levels...

On demand and prophylaxis usage of FVIII/ FIX concentrates for the therapeutic management of hemophilia has greatly changed quality of life, and healthy life span of affected patients. Availability of recombinant therapeutic FVIII and FIX products, and of their long-acting variants, further improves the treatment constraints, and progressively permits to hemophiliacs to have an almost normal way of life. Unlimited amounts of recombinant or engineered substitutive products become available, and open new avenues for extending the benefits of prophylaxis to all hemophiliac patients, not only in economically advanced territories, but also in emerging and developing countries, worldwide...

Hemophilia-a bleeding disorder due to the lack of clotting factors-is mostly induced by genetic factors. Its most common type is hemophilia A. Hemorrhage in hemophilia A may occur in several different sites of the body, including those inside the oral cavity, such as mucous membrane and gum. However, only a few studies and case reports on dental issues of hemophilia A patients have been conducted. In clinical dentistry, treatment procedures are invasive, possibly leading to more severe bleeding, especially in hemophilia A cases...
