Mother-to-child transmission of HIV-2 infection from 1986 to 2007 in the ANRS French Perinatal Cohort EPF-CO1.

Background: Management of pregnant women with human immunodeficiency virus (HIV) type 2 infection remains unclear because of its low prevalence and important differences from HIV-1.

Methods: Pregnant women monoinfected with HIV-2 or HIV-1 and their infants enrolled in the prospective, national, multicenter French Perinatal Cohort between 1986 and 2007.

Results: Overall, 2.

Epidemiology and outcome of invasive fungal diseases in patients with chronic granulomatous disease: a multicenter study in France.

Background: Chronic granulomatous disease (CGD) is a rare inherited phagocytic disorder resulting in an increased susceptibility to infections including invasive fungal diseases (IFDs) and inflammatory complications. This study is aimed at assessing the incidence, prevalence, and outcome of IFDs among CGD patients followed in France.

Methods: CGD patients were identified through the French national registry for primary immunodeficiencies (PID) held by the French national reference Centre of PID (Centre de Référence Déficits Immunitaires Héréditaires), which comprises a total of 3083 patients including 155 with CGD followed between 1976 and 2008.

Transplantation of hematopoietic stem cells and long-term survival for primary immunodeficiencies in Europe: entering a new century, do we do better?

Background: Hematopoietic stem cell transplantation remains the only treatment for most patients with severe combined immunodeficiencies (SCIDs) or other primary immunodeficiencies (non-SCID PIDs).

Objective: To analyze the long-term outcome of patients with SCID and non-SCID PID from European centers treated between 1968 and 2005.

Methods: The product-limit method estimated cumulative survival; the log-rank test compared survival between groups.

Efficacy of gene therapy for X-linked severe combined immunodeficiency.

Background: The outcomes of gene therapy to correct congenital immunodeficiencies are unknown. We reviewed long-term outcomes after gene therapy in nine patients with X-linked severe combined immunodeficiency (SCID-X1), which is characterized by the absence of the cytokine receptor common gamma chain.

Methods: The nine patients, who lacked an HLA-identical donor, underwent ex vivo retrovirus-mediated transfer of gamma chain to autologous CD34+ bone marrow cells between 1999 and 2002.

Long-term outcomes in adolescents perinatally infected with HIV-1 and followed up since birth in the French perinatal cohort (EPF/ANRS CO10).

BACKGROUND. Increasing numbers of children perinatally infected with human immunodeficiency virus (HIV) are reaching adolescence, largely because of advances in treatment over the past 10 years, but little is known about their current health status. We describe here the living conditions and clinical and immunovirologic outcomes at last evaluation among this pioneering generation of adolescents who were born before the introduction of prophylaxis for vertical transmission and whose infections were diagnosed at a time when treatment options were limited.

Is the recommended once-daily dose of lamivudine optimal in West African HIV-infected children?

We aimed in this study to describe lamivudine concentration-time courses in treatment-naïve children after once-daily administration, to study the effects of body weight and age on lamivudine pharmacokinetics, and to simulate an optimized administration scheme. For this purpose, lamivudine concentrations were measured in 49 children after at least 2 weeks of didanosine-lamivudine-efavirenz treatment. A total of 148 plasma lamivudine concentrations were measured, and a population pharmacokinetic model was developed with NONMEM.

Late postnatal HIV infection in children born to HIV-1-infected mothers in a high-income country.

Objective: To evaluate the risk of late postnatal HIV-1 infection in nonbreastfed children enrolled in the French ANRS Cohort CO01 (EPF).

Methods: The EPF cohort has prospectively enrolled HIV-infected mother/child pairs with a low proportion of known breastfeeding (<0.2%).

In untreated HIV-1-infected children, PBMC-associated HIV DNA levels and cell-free HIV RNA levels are correlated to distinct T-lymphocyte populations.

Background: Clinical studies support biologically independent roles of cell-free HIV particles and HIV-infected cells in disease progression. The associations between the level of infected cells and immune markers have been poorly studied, particularly in perinatally infected children.

Objective: We tested the hypothesis that independent roles of cell-free virus and infected cells in HIV pathogenesis should be revealed by different associations between each of them and specific immune markers.

Autoantibodies against IL-17A, IL-17F, and IL-22 in patients with chronic mucocutaneous candidiasis and autoimmune polyendocrine syndrome type I.

Most patients with autoimmune polyendocrine syndrome type I (APS-I) display chronic mucocutaneous candidiasis (CMC). We hypothesized that this CMC might result from autoimmunity to interleukin (IL)-17 cytokines. We found high titers of autoantibodies (auto-Abs) against IL-17A, IL-17F, and/or IL-22 in the sera of all 33 patients tested, as detected by multiplex particle-based flow cytometry.

Factors predictive of successful darunavir/ritonavir-based therapy in highly antiretroviral-experienced HIV-1-infected patients (the DARWEST study).

Background: Darunavir (DRV) is the latest protease inhibitor (PI) to be approved for antiretroviral-naive and -experienced HIV-infected patients.

Objectives: We examined virologic and immunologic outcomes of highly antiretroviral-experienced patients with triple-class drug resistance receiving DRV/r-based regimens, and attempted to identify factors predictive of virologic success.

Study Design: We studied patients beginning a ritonavir-boosted DRV (DRV/r 600/100mg twice daily)-containing regimen.

Factors associated with mother-to-child transmission of HIV-1 despite a maternal viral load <500 copies/ml at delivery: a case-control study nested in the French perinatal cohort (EPF-ANRS CO1).

Background: The rate of mother-to-child transmission (MTCT) of human immunodeficiency virus (HIV) type 1 is as low as 0.5% in non-breast-feeding mothers who delivered at term while receiving antiretroviral therapy with a plasma viral load <500 copies/mL. This situation accounted for 20% of the infected children born during the period 1997-2006 in the French Perinatal Cohort.

Nonvertical, nonsexual transmission of human immunodeficiency virus in children.

In a cohort of 450 human immunodeficiency virus (HIV)-infected children followed up in Maputo, Mozambique, 22 were born to HIV-uninfected mothers and had no history of sexual abuse. A case record review of these nonvertically, nonsexually infected children as well as a case-control study strongly suggests health care as possible source of infection for many of these children. This facet of the pediatric HIV epidemic should not be overlooked.

Universal antiretroviral therapy for pregnant and breast-feeding HIV-1-infected women: towards the elimination of mother-to-child transmission of HIV-1 in resource-limited settings.

Prevention of mother-to-child transmission (MTCT) of human immunodeficiency virus type 1 (HIV-1) remains a challenge in most resource-limited settings, particularly in Africa. Single-dose and short-course antiretroviral (ARV) regimens are only partially effective and have failed to achieve wide coverage despite their apparent simplicity. More potent ARV combinations are restricted to pregnant women who need treatment for themselves and are also infrequently used.

Risk of extended viral resistance in human immunodeficiency virus-1-infected Mozambican children after first-line treatment failure.

Background: Resistant virus may be selected by sub-optimal control of HIV-1 replication during antiretroviral treatment. The incidence and profile of resistance in children receiving World Health Organization-recommended treatment remains to be evaluated on a large scale.

Goals: Assessment of the frequency and profile of resistant virus in HIV-1-infected children, treated for at least 6 months with stavudine/zidovudine + lamivudine + nevirapine and presenting virological failure in a large access program in Maputo, Mozambique.

Hematopoietic stem cell gene therapy with a lentiviral vector in X-linked adrenoleukodystrophy.

X-linked adrenoleukodystrophy (ALD) is a severe brain demyelinating disease in boys that is caused by a deficiency in ALD protein, an adenosine triphosphate-binding cassette transporter encoded by the ABCD1 gene. ALD progression can be halted by allogeneic hematopoietic cell transplantation (HCT). We initiated a gene therapy trial in two ALD patients for whom there were no matched donors.

Actinomyces in chronic granulomatous disease: an emerging and unanticipated pathogen.

Background: Chronic granulomatous disease (CGD) is a rare inherited disease of the phagocyte NADPH oxidase system that causes defective production of toxic oxygen metabolites, impaired bacterial and fungal killing, and recurrent life-threatening infections, mostly by catalase-producing organisms. We report for the first time, to our knowledge, chronic infections with Actinomyces species in 10 patients with CGD. Actinomycosis is a chronic granulomatous condition that commonly manifests as cervicofacial, pulmonary, or abdominal disease, caused by slowly progressive infection with oral and gastrointestinal commensal Actinomyces species.

Influence of development, HIV infection, and antiretroviral therapies on the gene expression profiles of ABC transporters in human lymphocytes.

The efficacy of drugs acting on lymphocytes like anticancer, immunosuppressive, and antiretroviral drugs depends on their intracellular concentrations, which could be modulated by membrane efflux pumps belonging to the ABC transporter superfamily. The gene expression profiles of 6 main ABC transporters (MDR1, MRP1, MRP3, MRP4, MRP5, and BCRP) were established in lymphocytes from birth to adulthood using blood samples from 57 children and 15 adults (34 and 5 HIV-infected, respectively). Gene expression levels were quantified by quantitative RT-PCR.

Perinatal acquisition of drug-resistant HIV-1 infection: mechanisms and long-term outcome.

Background: Primary-HIV-1-infection in newborns that occurs under antiretroviral prophylaxis that is a high risk of drug-resistance acquisition. We examine the frequency and the mechanisms of resistance acquisition at the time of infection in newborns.

Patients And Methods: We studied HIV-1-infected infants born between 01 January 1997 and 31 December 2004 and enrolled in the ANRS-EPF cohort.

Pharmacokinetics, safety and efficacy of darunavir/ritonavir in treatment-experienced children and adolescents.

Objective: To assess pharmacokinetics, safety and efficacy of darunavir/ritonavir (DRV/r) and optimized background regimen in treatment-experienced patients (6-17 years).

Design: Forty-eight-week, open-label, two-part, phase II study.

Methods: In part I, 44 patients were randomized (1: 1 ratio) to receive a body weight-adjusted, adult-equivalent dose (group A) or a 20-33% higher DRV/r twice daily (b.

Kinetics of nasopharyngeal shedding of novel H1N1 (swine-like) influenza A virus in an immunocompetent adult under oseltamivir therapy.

We describe a patient with confirmed novel H1N1 (swine-like) influenza A virus who had daily nasal swabs tested during oseltamivir therapy. Nasal shedding remained positive for 2 days and became negative on day 3. This report presents the first available data on the kinetics of shedding of this novel virus under antiviral therapy.

Enhancing essential amino acids and health benefit components in grain crops for improved nutritional values.

Improving essential amino acids or protein content, along with other phytonutrients in the food crops, will affect a great portion of the world population, especially in developing countries where rice grain is the main source of protein. Malnutrition, including deficiencies in protein/energy, iron/zinc, vitamin A, and iodine, causes a total 24,000 deaths per day worldwide. The problem is severe where rice is the major staple food.

Relationship of CD4+ T-cell counts and plasma HIV-1 RNA levels with serological HBeAg/anti-HBe patterns obtained in West-African HBV-HIV-1-co-infected children.

HBeAg/anti-HBe and hepatitis B virus (HBV) DNA from 34 HIV-1-infected children from Ivory Coast with chronic hepatitis B (CHB) were longitudinally analyzed according to CD4 and HIV-1 RNA. The mean CD4% value was significantly (p = 0.03) lower in 59 (52.
