Objective: To determine the effects of human immunodeficiency virus (HIV) infection on children's development by identifying neurological and environmental variables associated with neuropsychological measures of cognitive development in HIV-seronegative (HIV-) and HIV-seropositive (HIV+)children and adolescents with hemophilia.

Methods: Participants (N = 298; 60% HIV+) were males ages 7-19 years enrolled in the Hemophilia Growth and Development Study (HGDS). Least squares modeling was used to determine whether there was a difference at baseline in mean neuropsychological test scores by HIV status, age, and neurological baseline findings, adjusting for selected environmental and medical history variables.

Results: The participants were within age expectations for general intelligence. Variables associated with lowered neuropsychological performance included academic problems, coordination and/or gait abnormalities, parents' education, and previous head trauma.

Conclusions: Hemophilia-related morbidity has a subtle adverse influence on cognitive performance. HIV infection was not associated with neuropsychological dysfunction in this group even when MRI abnormalities were present.

Introduction: We have reanalyzed the genomic data from the International Collaboration for the Genomics of HIV (ICGH), focusing on HIV-1 Elite Controllers (EC).

Methods: A genome-wide association study (GWAS) was performed, comparing 543 HIV-1 EC individuals with 3,272 uninfected controls (CTR) of European ancestry. 8 million single nucleotide polymorphisms (SNPs) and HLA class I and class II gene alleles were imputed to compare EC and CTR.

Background: Hemophilic arthritis (HA) is associated with significant changes in the morphology of mature knee joints due to abnormal growth plate development. Previous studies have established marked distinctions between the femur and tibia of subjects with Haemophilia and those with osteoarthritis (OA). This study explored the morphological characteristics of the patella and patellofemoral joint in subjects with Haemophilia.

Adeno-associated virus (AAV) vectors have demonstrated safety and efficacy for gene transfer to hepatocytes in preclinical models, in various clinical trials and from a clinical experience with a growing number of approved gene therapy products. Although the exact duration is unknown, the expression of therapeutic genes in hepatocytes remains stable for several years after a single administration of the vector at clinically relevant doses in adult patients with hemophilia and other inherited metabolic disorders. However, clinical applications, especially for diseases requiring high AAV vector doses by intravenous administrations, have raised several concerns.

Article Synopsis
  • Researchers are exploring liver sinusoidal endothelial cells (LSECs) and their progenitor cells (LPCs) from human pluripotent stem cells (PSCs) as potential treatments for hemophilia A, a condition caused by insufficient coagulation factor VIII (FVIII) production.* -
  • The study aimed to enhance the process of mesoderm differentiation to efficiently produce LSEC-like cells from human induced pluripotent stem cells (iPSCs), observing a successful differentiation rate of approximately 65% for LPCs and 54% for LSEC-like cells.* -
  • Optimizing specific factors like CHIR99021 and bone morphogenetic protein 4 led to significant FVIII protein secretion from L

Background: Hereditary hemorrhagic telangiectasia (HHT) is a bleeding disorder characterized by arteriovenous malformations, commonly presenting with epistaxis and gastrointestinal (GI) bleeding. Bleeding symptoms may be difficult to manage and may become life-threatening, with many patients developing dependence on parenteral iron and/or blood transfusion. There is a growing body of evidence that antiangiogenic therapies may be effective in management of bleeding symptoms, presumably targeting pathogenic HHT pathways such as vascular endothelial growth factor receptor.
