The objective of this study was to determine and compare the cost to treat HIV(+) and HIV(-) pediatric patients both before and after HIV prophylaxis became the standard of care. Retrospective chart review of a pediatric HIV/AIDS specialty clinic's medical charts was conducted for clinical and healthcare utilization data on 125 children diagnosed from 1986 to 2007. Mean HIV-related costs were compared using bootstrapped t-tests for children born in the pre-prophylaxis (1979-1993) and prophylaxis eras (1994-2007).

The covalent attachment of lysine 63-linked polyubiquitin to the zinc-finger domain of IKBKG/NEMO (also known as IKKγ) is necessary for full activation of NF-κB. Impairments of this biochemical mechanism explain the deleterious effects of hypomorphic NEMO mutations on NF-κB signaling function in humans suffering from X-linked ectodermal dysplasia and immunodeficiency. Nevertheless, the biological function of the NEMO zinc-finger domain in the regulation of mitogen-activated protein kinase (MAPK) activity is poorly understood.

Objective: Life has changed dramatically for infants exposed perinatally to HIV to HIV primarily because of a successful translational research program that has also affected treatment costs. We compared treatment costs among HIV+ patients in an HIV/AIDS specialty clinic across 3 treatment eras: monotherapy (pre-1990), combination therapy (1990-1996), and highly active antiretroviral therapy (HAART) (1997-2007). We also estimated cumulative health care costs among pediatric HIV/AIDS patients born in each era.

Background: Despite the high prevalence of altered iron metabolism in children with human immunodeficiency virus (HIV) disease, these alterations have not been well studied.

Procedures: Twenty-six children with HIV disease underwent laboratory evaluation to determine the presence of anemia, and to classify the anemia as iron-deficiency anemia or anemia of chronic disease.

Results: Half of the children had an alteration in iron metabolism: 6 were iron deficient, 4 had hyperferritinemia, and 3 demonstrated hyperferritinemia with iron deficiency.

This study aimed to determine lamivudine disposition in infants and to construct an appropriate dose adjustment for age, given the widespread use of lamivudine for both the prevention of mother-to-child transmission of human immunodeficiency virus (HIV) and the treatment of HIV-infected infants. Using a pooled-population approach, the pharmacokinetics of lamivudine in HIV-exposed or -infected infants from four Pediatric AIDS Clinical Trials Group studies were assessed. Ninety-nine infants provided 559 plasma samples for measurement of lamivudine concentrations.

JC virus infection of the brain typically causes progressive multifocal leukoencephalopathy, a demyelinating disease that rarely involves gray matter. This report presents a case of cerebellar degeneration associated with JC virus infection in a male with CD40 ligand deficiency resulting in hyperimmunoglobulin M type 1. This patient exhibited a progressive cerebellar ataxia with progressive atrophy of the cerebellar cortex in association with the presence of JC virus in the spinal fluid.

Human immunodeficiency virus-infected women (n=16) received indinavir (800 mg three times a day) plus zidovudine plus lamivudine from 14 to 28 weeks of gestation to 12 weeks postpartum. Two women and eight infants experienced grade 3 or 4 toxicities that were possibly treatment related. Indinavir area under the plasma concentration-time curve was 68% lower antepartum versus postpartum, suggesting increased intestinal and/or hepatic CYP3A activity during pregnancy.

Wiskott-Aldrich syndrome (WAS) is a primary immunodeficiency that manifests as increased susceptibility to many pathogens. Although the spectrum of infections suffered by WAS patients is consistent with defects in neutrophil (PMN) function, the consequences of WAS protein (WASp) deficiency on this innate immune cell have been unclear. We report that deficiency of WASp in both human and murine PMNs resulted in profound defects in clustering of beta2 integrins, leading to defective adhesion and transendothelial migration under conditions of physiologic shear flow.

Background: Human immunodeficiency virus (HIV)-infected patients have weak responses to vaccines and may require revised immunization regimens. We investigated the safety and immunogenicity of 2 doses of hepatitis A virus (HAV) vaccine followed by a booster dose in HIV-infected children receiving stable highly active antiretroviral therapy.

Methods: A total of 235 children with CD4+ T cell percentages > or = 20% received 2 vaccine doses 24 weeks apart, and 117 received a third vaccine dose after 104 weeks.

Adenosine deaminase (ADA)-deficient Severe Combined Immunodeficiency (ADA-deficient SCID) is characterized by impaired lymphocyte development and function resulting from the adenosine metabolism defect. Enzyme replacement therapy with polyethylene glycol-conjugated adenosine deaminase (PEG-ADA) minimizes infectious complications of ADA-deficient patients who have not received bone marrow transplantation. In PEG-ADA therapy, enzymatically active ADA continuously circulates to act as a metabolic sink, detoxifying the adenosine and deoxyadenosine metabolites that accumulate to high levels in the absence of ADA.

The AAMC's Increasing Women's Leadership Project Implementation Committee examined four years of data on the advancement of women in academic medicine. With women comprising only 14% of tenured faculty and 12% of full professors, the committee concludes that the progress achieved is inadequate. Because academic medicine needs all the leaders it can develop to address accelerating institutional and societal needs, the waste of most women's potential is of growing importance.

Background: Some studies suggest that combination antiretroviral therapy in pregnant women with human immunodeficiency virus type 1 (HIV-1) infection increases the risk of premature birth and other adverse outcomes of pregnancy.

Methods: We studied pregnant women with HIV-1 infection who were enrolled in seven clinical studies and delivered their infants from 1990 through 1998. The cohort comprised 2123 women who received antiretroviral therapy during pregnancy (monotherapy in 1590, combination therapy without protease inhibitors in 396, and combination therapy with protease inhibitors in 137) and 1143 women who did not receive antiretroviral therapy.

Infants born to human immunodeficiency virus type 1 (HIV-1)-infected mothers were immunized at birth and at ages 4, 12, and 20 weeks with low-, medium-, or high-dose recombinant gp120 vaccine with MF59 adjuvant (HIV-1(SF-2); n=52) or with MF59 alone as a placebo (n=9). An accelerated schedule (birth and ages 2, 8, and 20 weeks) was used for an additional 10 infants receiving the defined optimal dose and for 3 infants receiving placebo. At 24 weeks, anti-gp120 ELISA titers were greater for vaccine-immunized than for placebo-immunized infants on both schedules, and 87% of vaccinees had a vaccine-induced antibody response.
