Investigation into a recent cluster of acute hepatitis in children from the southeastern United States identified human adenovirus (HAdV) DNAemia in all 9 cases. Molecular genotyping in 5 of 9 (56%) children identified HAdV type 41 in all cases (100%). Importantly, 2 children from this cluster progressed rapidly to pediatric acute liver failure (PALF) and required liver transplantation. HAdV type 41, a known cause of self-limited gastroenteritis, has not previously been associated with severe cholestatic hepatitis and liver failure in healthy children. Adenovirus polymerase chain reaction assay and sequencing of amplicons performed on DNA extracted from formalin-fixed, paraffin-embedded liver tissue …

Faculty, Staff and Students Publications

Several factors occurring in early life, including lower respiratory tract illnesses (LRIs), are involved in determining lung structure and function in adulthood, but the effects of these factors on lung development remain largely unknown. Hereby, we evaluated the parameters from computed tomography (CT) scans performed at the age of 26 years in 39 subjects from the birth cohort of the Tucson Children's Respiratory Study (TCRS) in order to determine the relationship between early childhood factors and lung structural changes in young adult life. We found that participants with LRIs in childhood had increased air trapping at the age of 26 …

Multi-Omic Association Study Identifies Dna Methylation-Mediated Genotype And Smoking Exposure Effects On Lung Function In Children Living In Urban Settings, Matthew Dapas, Michelle A. Gill, Et Al

2020-Current year OA Pubs

Impaired lung function in early life is associated with the subsequent development of chronic respiratory disease. Most genetic associations with lung function have been identified in adults of European descent and therefore may not represent those most relevant to pediatric populations and populations of different ancestries. In this study, we performed genome-wide association analyses of lung function in a multiethnic cohort of children (n = 1,035) living in low-income urban neighborhoods. We identified one novel locus at the TDRD9 gene in chromosome 14q32.33 associated with percent predicted forced expiratory volume in one second (FEV1) (p = 2.4x10-9; βz = -0.31, …

Structural And Biophysical Characterization Of The Secreted, Β-Helical Adhesin Etpa Of Enterotoxigenic Escherichia Coli, Clifford Manyo Ntui, James M. Fleckenstein, Wolf-Dieter Schubert

2020-Current year OA Pubs

Enterotoxigenic Escherichia coli (ETEC) is a diarrhoeal pathogen associated with high morbidity and mortality especially among young children in developing countries. At present, there is no vaccine for ETEC. One candidate vaccine antigen, EtpA, is a conserved secreted adhesin that binds to the tips of flagellae to bridge ETEC to host intestinal glycans. EtpA is exported through a Gram-negative, two-partner secretion system (TPSS, type Vb) comprised of the secreted EtpA passenger (TpsA) protein and EtpB (TpsB) transporter that is integrated into the outer bacterial membrane. TpsA proteins share a conserved, N-terminal TPS domain followed by an extensive C-terminal domain with …

Medical Ethics Principles Underscore Advocating For Human Papillomavirus Vaccine, C Mary Healy, Lara S Savas, Ross Shegog, Rebecca Lunstroth, Sally W Vernon

Faculty, Staff and Student Publications

Studies have consistently shown that vaccination rates against human papillomavirus (HPV) lag far behind other adolescent vaccinations recommended at the same age, resulting in exposing adolescents to unnecessary future risk of infection, and genital and head and neck cancers. Studies also have demonstrated that a major barrier to vaccination is lack of a strong provider recommendation. Factors that providers offer for failing to give a strong recommendation range from perception that the child is not at risk or the need to explain that the vaccine is not mandated (lack of equity and justice) or respect for parental autonomy. We look …

In late August 2021, a boy aged 7 years was bitten by a bat while he was playing outside his apartment home in Medina County, Texas. He informed his parents; however, no rabies postexposure prophylaxis (PEP) was sought because there were no visible bite marks, and the family was unaware that contact with a bat, including in the absence of visible bite marks, might cause rabies. Approximately 2 months later, the child was hospitalized for altered mental status, seizures, and hypersalivation and ultimately received a diagnosis of rabies. Experimental therapies were attempted; however, the child died 22 days after symptom …

How I Approach Leishmaniasis: Diagnosis And Treatment In The United States, Tara E Ness, Rachel Martin-Blais, Jill E Weatherhead

Faculty, Staff and Students Publications

Leishmaniasis is a vector-borne disease caused by over 20 species of obligate intracellular protozoa belonging to the genus Leishmania. Leishmaniasis has a global distribution, including in the United States, and can cause a spectrum of clinical syndromes, including cutaneous, mucosal, and visceral diseases depending on host factors and the infecting Leishmania spp. Accurate diagnosis, including Leishmania species identification, is an important step to guide the most appropriate therapeutic intervention. Antileishmanial therapy is dependent on the Leishmania spp. identified, the clinical syndrome, and the child's immune system. However, many treatment regimens for children have been extrapolated from adult clinical trials, which …

2020-Current year OA Pubs

BACKGROUND: A de novo, pathogenic, missense variant in UBTF, c.628G>A p.Glu210Lys, has been described as the cause of an emerging neurodegenerative disorder, Childhood-Onset Neurodegeneration with Brain Atrophy (CONDBA). The p.Glu210Lys alteration yields a positively charged stretch of three lysine residues. Functional studies confirmed this change results in a stronger interaction with negatively charged DNA and gain-of-function activity when compared to the wild-type sequence. The CONDBA phenotype reported in association with p.Glu210Lys consists of normal early-neurodevelopment followed by progressive motor, cognitive, and behavioral regression in early-to-middle childhood.

BACKGROUND: Newborn screening can identify neonatal T-cell lymphopenia through detection of a low number of copies of T-cell receptor excision circles in dried blood spots collected at birth. After a positive screening result, further diagnostic testing is required to determine whether the subject has severe combined immunodeficiency or other causes of T-cell lymphopenia. Even after thorough evaluation, approximately 15% of children with a positive result of newborn screening for T-cell receptor excision circles remain genetically undiagnosed. Identifying the underlying genetic etiology is necessary to guide subsequent clinical management and family planning.
