Metabolic studies are described in a patient who presented at 3 weeks of age with severe anaemia, hyperbilirubinaemia and hypotonicity. Clinically, glycogen storage disease type II (Pompe disease) was suspected because of a massively enlarged heart and hepatosplenomegaly. This was confirmed biochemically by the demonstration of glycogen accumulation in(More)
Kaposi's sarcoma-associated herpesvirus (KSHV) is linked to human malignancies. The majority of tumor cells harbor latent virus, and a small percentage undergo spontaneous lytic replication. Both latency and lytic replication are important for viral pathogenesis and spread, but the cellular players involved in the switch between the two viral life-cycle(More)
UNLABELLED The K1 gene product of Kaposi's sarcoma-associated herpesvirus (KSHV) is encoded by the first open reading frame (ORF) of the viral genome. To investigate the role of the K1 gene during the KSHV life cycle, we constructed a set of recombinant viruses that contained either wild-type (WT) K1, a deleted K1 ORF (KSHVΔK1), stop codons within the K1(More)
Maribavir (MBV) inhibits Epstein-Barr virus (EBV) replication and the enzymatic activity of the viral protein kinase BGLF4. MBV also inhibits expression of multiple EBV transcripts during EBV lytic infection. Here we demonstrate, with the use of a BGLF4 knockout virus, that effects of MBV on transcription take place primarily through inhibition of BGLF4.(More)
BACKGROUND Contemporary descriptions of classical Hodgkin lymphoma (cHL) are lacking from sub-Saharan Africa where human immunodeficiency virus (HIV) and Epstein-Barr virus (EBV) are prevalent. METHODS We describe a prospective cHL cohort in Malawi enrolled from 2013 to 2015. Patients received standardized treatment and evaluation, including HIV status(More)
OBJECTIVE Herpesvirus shedding in the oral cavity was analyzed to determine if presence in the oral compartment correlates with systemic changes in HIV-associated immune deficiency as measured by CD4 cell counts, plasma HIV viral load and presence of AIDS-defining events. DESIGN A5254 is a multicenter, cross-sectional, single-visit study to evaluate oral(More)
INTRODUCTION Clinical reports of multicentric Castleman disease (MCD) from sub-Saharan Africa (SSA) are scarce despite high prevalence of HIV and Kaposi sarcoma-associated herpesvirus (KSHV). Our objective is to describe characteristics and survival for HIV-associated MCD patients in Malawi. To our knowledge, this is the first HIV-associated MCD case series(More)
Point-of-care tools are needed in sub-Saharan Africa (SSA) to improve pediatric Burkitt lymphoma (BL) diagnosis and treatment. We evaluated plasma Epstein-Barr virus (pEBV) DNA as a pediatric BL biomarker in Malawi. Prospectively enrolled children with BL were compared to classical Hodgkin lymphoma (cHL) and nonlymphoma diagnoses. Pediatric BL patients(More)
