    Data on zidovudine pharmacokinetics in children dosed using World Health Organization weight bands are limited. About 45 HIV-infected, Ugandan children, 3.4 (2.6-6.2) years, had intensive pharmacokinetic sampling. Geometric mean zidovudine AUC0-12h was 3.0 h.mg/L, which is higher than previously observed in adults, and was independently higher in those receiving higher doses, younger and underweight children. Higher exposure was also marginally associated with lower hemoglobin. PMID:24736440

    2010-01-01

    Background Low concentrations of serum zinc have been reported in HIV infected adults and are associated with disease progression and an increased risk of death. Few studies have been conducted in HIV infected children in Africa. We determined serum zinc levels and factors associated with zinc deficiency in HIV infected Ugandan children. Methods We measured the baseline zinc status of 247 children aged 1-5 years enrolled in a randomised trial for multiple micronutrient supplementation at paediatric HIV clinics in Uganda (http://ClinicalTrials.gov NCT00122941). Zinc status was determined using inductively coupled atomic emission spectrophotometry (ICP-AES). Clinical and laboratory characteristics were compared among zinc deficient (zinc < 10.0 μmol/L) and non deficient children. Logistic regression was used to determine predictors of low serum zinc. Results Of the 247 children, 134 (54.3%) had low serum zinc (< 10.0 μmol/L). Of the 44 children on highly active antiretroviral therapy (HAART), 13 (29.5%) had low zinc compared to 121/203 (59.6%) who were not on HAART. Overall, independent predictors of low zinc were fever (OR 2.2; 95%CI 1.1 - 4.6) and not taking HAART (OR 3.7; 95%CI 1.8 - 7.6). Conclusion Almost two thirds of HAART naïve and a third of HAART treated HIV infected children were zinc deficient. Increased access to HAART among HIV infected children living in Uganda might reduce the prevalence of zinc deficiency. PMID:20858275

    Background Without virologic testing, HIV-infected African children starting antiretroviral (ARV)-therapy are at risk for undetected virological failure and the development of ARV-resistance. We sought to determine the prevalence of early virologic failure (EVF), to characterize the evolution of ARV-resistance mutations, and to predict the impact on second-line therapy. Methods The prevalence of EVF (HIV-RNA >400 copies/mL on sequential visits after 6 months of therapy) was identified among 120 HIV-infected Ugandan children starting ARV-therapy. ARV-mutations were identified by population sequencing of HIV-1 pol in sequential archived specimens. Composite discrete genotypic susceptibility scores (dGSS) were determined for second-line ARV-regimens. Results EVF occurred in 16 (13%) children and persisted throughout a median (IQR) 938 (760-1066) days of follow-up. M184V and non-nucleoside-reverse-transcriptase-inhibitor-associated mutations emerged within 6 months of EVF; thymidine-analog-mutations arose after 12 months. Worse dGSS scores correlated with increasing duration of failure (Spearman R = −0.47, p=0.001). Only 1 child met World Health Organization CD4 criteria for ARV-failure at the time of EVF or during the follow-up period. Conclusions A significant portion of HIV-infected African children experience EVF that would be undetected using CD4/clinical monitoring and resulted in the accumulation of ARV-mutations that could compromise second line therapy options.

    There is limited understanding of the epidemiology of meningitis among human immunodeficiency virus (HIV)-infected populations in sub-Saharan Africa. We conducted a prospective cohort study of HIV-infected adults with suspected meningitis in Uganda, to comprehensively evaluate the etiologies of meningitis. Intensive cerebrospiral fluid (CSF) testing was performed to evaluate for bacterial, viral, fungal, and mycobacterial etiologies, including neurosyphilis,16s ribosomal DNA (rDNA) polymerase chain reaction (PCR) for bacteria, Plex-ID broad viral assay, quantitative-PCR for HSV-1/2, cytomegalovirus (CMV), Epstein–Barr virus (EBV), and Toxoplasma gondii; reverse transcription-PCR (RT-PCR) for Enteroviruses and arboviruses, and Xpert MTB/RIF assay. Cryptococcal meningitis accounted for 60% (188 of 314) of all causes of meningitis. Of 117 samples sent for viral PCR, 36% were EBV positive. Among cryptococcal antigen negative patients, the yield of Xpert MTB/RIF assay was 22% (8 of 36). After exclusion of cryptococcosis and bacterial meningitis, 61% (43 of 71) with an abnormal CSF profile had no definitive diagnosis. Exploration of new TB diagnostics and diagnostic algorithms for evaluation of meningitis in resource-limited settings remains needed, and implementation of cryptococcal diagnostics is critical.

    Abstract A high prevalence of liver stiffness, as determined by elevated transient elastography liver stiffness measurement, was previously found in a cohort of HIV-infected Ugandans in the absence of chronic viral hepatitis. Given the role of immune activation and microbial translocation in models of liver disease, a shared immune mechanism was hypothesized in the same cohort without other overt causes of liver disease. This study examined whether HIV-related liver stiffness was associated with markers of immune activation or microbial translocation (MT). A retrospective case-control study of subjects with evidence of liver stiffness as defined by a transient elastography stiffness measurement ≥9.3 kPa (cases=133) and normal controls (n=133) from Rakai, Uganda was performed. Cases were matched to controls by age, gender, HIV, hepatitis B virus (HBV), and highly active antiretroviral therapy (HAART) status. Lipopolysaccharide (LPS), endotoxin IgM antibody, soluble CD14 (sCD14), C-reactive protein (CRP), and D-dimer levels were measured. Conditional logistic regression was used to estimate adjusted matched odds ratios (adjMOR) and 95% confidence intervals. Higher sCD14 levels were associated with a 19% increased odds of liver stiffness (adjMOR=1.19, p=0.002). In HIV-infected individuals, higher sCD14 levels were associated with a 54% increased odds of having liver stiffness (adjMOR=1.54, p<0.001); however, the opposite was observed in HIV-negative individuals (adjMOR=0.57, p=0.001). No other biomarker was significantly associated with liver stiffness, and only one subject was found to have detectable LPS. Liver stiffness in HIV-infected Ugandans is associated with increased sCD14 indicative of monocyte activation in the absence of viral hepatitis or microbial translocation, and suggests that HIV may be directly involved in liver disease.

    Cryptococcus neoformans is an encapsulated fungal pathogen that is remarkable for its tendency to cause meningoencephalitis, especially in patients with AIDS. While disease is less common in children than adults, it remains an important cause of morbidity and mortality among HIV-infected children without access to anti-retroviral therapy. This review highlights recent insights into both the biology and treatment of cryptococcosis with a special emphasis on the pediatric literature. PMID:27443557

    Rheumatic heart disease (RHD) remains highly prevalent in resource-constrained settings around the world, including countries with high rates of HIV/AIDS. Although both are immune-mediated diseases, it is unknown whether HIV modifies the risk or progression of RHD. We performed screening echocardiography to determine the prevalence of latent RHD in 488 HIV-infected children aged 5-18 in Kampala, Uganda. The overall prevalence of borderline/definite RHD was 0.82% (95% confidence interval: 0.26% to 2.23%), which is lower than the published prevalence rates of 1.5%-4% among Ugandan children. There may be protective factors that decrease the risk of RHD in HIV-infected children. PMID:26413847

    Background Malnutrition may impact the pharmacokinetics (PK) of antiretroviral medications and virologic responses in HIV-infected children. We therefore evaluated the PK of nevirapine (NVP), efavirenz (EFV) and lopinavir (LPV) in associations with nutritional status in a cohort of HIV-infected Ugandan children. Methods Sparse dried blood spot (DBS) samples from Ugandan children were used to estimate plasma concentrations. Historical PK data from children from three resource-rich countries (RRC) were utilized to develop the PK models. Results Concentrations in 330 DBS from 163 Ugandan children aged 0.7–7 years were analyzed in reference to plasma PK data (1189 samples) from 204 children from RRC aged 0.5–12 years. Among Ugandan children 48% was malnourished (underweight, thin or stunted). Compared to RRC, Ugandan children exhibited reduced bioavailability of EFV and LPV; 11% (P=0.045) and 18% (P=0.008) respectively. In contrast, NVP bioavailability was 46% higher in Ugandan children (P<0.001) with a trend towards greater bioavailability when malnourished. Children receiving LPV, EFV or NVP had comparable risk of virologic failure. Among children on NVP, low height and weight for age Z-scores were associated with reduced risk of virologic failure (p=0.034, p=0.068 respectively). Conclusions Ugandan children demonstrated lower EFV and LPV and higher NVP exposure compared to children in RRC, perhaps reflecting the consequence of malnutrition on bioavailability. In children receiving NVP, the relation between exposure, malnutrition and outcome turned out to be marginally significant. Further investigations are warranted using more intensive PK measurements and adequate adherence assessements, to further assess causes of virologic failure in Ugandan children. PMID:25742090

    High adherence is critical for achieving clinical benefits of HIV antiretroviral therapy (ART) and particularly challenging for children. We conducted 35 qualitative interviews with caregivers of HIV-infected Ugandan children who were followed in a longitudinal study of real-time ART adherence monitoring; 18 participants had undetectable HIV RNA, while 17 had detectable virus. Interviews blinded to viral suppression status elicited information on adherence experiences, barriers and facilitators to adherence, and social support. Using an inductive content analytic approach, we identified 'lack of resources,' 'Lazarus effect,' 'caregiver's sense of obligation and commitment,' and 'child's personal responsibility' as categories of influence on adherence, and defined types of caregiver social support. Among children with viral suppression, high hopes for the child's future and ready access to private instrumental support appeared particularly important. These findings suggest clinical counseling should explore caregivers' views of their children's futures and ability to access support in overcoming adherence barriers. PMID:25323679

    The complete caries removal of deep/extensive dentin carious lesions with conventional procedures (high- and low-speed bur) may increase the risk of pulp exposure. In children with systemic diseases, such as HIV-infected children, the dental treatment proposed for the primary dentition with pulp involvement is tooth extraction once endodontic therapies cannot be guaranteed successfully. Therefore, the objective of this study was to describe 3 cases of alternative techniques for caries removal in extensive and/or deep dentin carious lesions in the primary dentition of HIV-infected children: (1) atraumatic restorative treatment (ART); (2) Carisolv; and (3) Papacarie.

    Perceived social standing (PSS) was evaluated as a determinant of differences in health outcomes among Ugandan HIV-infected adults from Kampala using cross-sectional study design. PSS was defined using the MacArthur scale of subjective social status translated and adapted for the study setting. Socio-demographic and psychosocial correlates of PSS ranking at enrollment were determined using linear regression models. High versus low PSS was defined based on the median PSS score and evaluated as a determinant of body mass index, hemoglobin, quality of life (QOL) and frailty-related phenotype via linear regression. A log-binomial regression model estimated the relative-risk of good, very good or excellent versus fair or poor self-rated health (SRH) in relation to PSS. Older age, increasing social support and material wealth were correlated with high PSS ranking, whereas female sex, experience of multiple stigmas and multiple depressive symptoms were correlated with low PSS ranking. High PSS participants were on average 1.1 kg/m(2) heavier, had 4.7 % lower frailty scores and 3.6 % higher QOL scores compared to low PSS patients (all p < 0.05); they were also more likely to self-classify as high SRH (RR 1.4, 95 % confidence interval 1.1, 1.7) but had comparable hemoglobin levels (p = 0.634). Low PSS correlated with poor physical and psychosocial wellbeing in HIV-positive Ugandan adults. The assessment of PSS as part of clinical management, combined with efforts to reduce stigma and improve social support, may identify and possibly reduce PSS-associated health inequality in Ugandan adults with HIV.

    The long-term impact on bone health of lifelong HIV infection and prolonged ART in growing and developing children is not yet known. Measures of bone health in youth must be interpreted in the context of expected developmental and physiologic changes in bone mass, size, density and strength that occur from fetal through adult life. Low bone mineral density (BMD) appears to be common in perinatally HIV-infected youth, especially outside of high-income settings, but data are limited and interpretation complicated by the need for better pediatric norms. The potential negative effects of tenofovir on BMD and bone mass accrual are of particular concern as this drug may be used more widely in younger children. Emphasizing good nutrition, calcium and vitamin D sufficiency, weight-bearing exercise and avoidance of alcohol and smoking are effective and available approaches to maintain and improve bone health in all settings. More data are needed to inform therapies and monitoring for HIV-infected youth with proven bone fragility. While very limited data suggest lack of marked increase in fracture risk for youth with perinatal HIV infection, the looming concern for these children is that they may fail to attain their expected peak bone mass in early adulthood which could increase their risk for fractures and osteoporosis later in adulthood.

    Antiretroviral therapy in children has expanded dramatically in low-income and middle-income countries. The World Health Organization revised its pediatric HIV guidelines to recommend initiation of antiretroviral therapy in all HIV-infected children younger than 2 years, regardless of CD4 count or clinical stage. The number of children starting life-long antiretroviral therapy should therefore expand dramatically over time. The early initiation of antiretroviral therapy has indisputable benefits for children, but there is a paucity of definitive information on the potential adverse effects. In this review, a comprehensive literature search was conducted to provide an overview of our knowledge about the complications of treating pediatric HIV. Antiretroviral therapy in children, as in adults, is associated with enhanced survival, reduction in opportunistic infections, improved growth and neurocognitive function, and better quality of life. Despite antiretroviral therapy, HIV-infected children may continue to lag behind their uninfected peers in growth and development. In addition, epidemic concurrent conditions, such as tuberculosis, malaria, and malnutrition, can combine with HIV to yield more rapid disease progression and poor treatment outcomes. Additional studies are required to evaluate the long-term effects of antiretroviral therapy in HIV-infected infants, children, and adolescents, particularly in resource-limited countries where concomitant infections and conditions may enhance the risk of adverse effects. There is an urgent need to evaluate drug-drug interactions in children to determine optimal treatment regimens for both HIV and coinfections. PMID:22138766

    The oral microbial community (microbiota) plays a critical role in human health and disease. Alterations in the oral microbiota may be associated with disorders such as gingivitis, periodontitis, childhood caries, alveolar osteitis, oral candidiasis and endodontic infections. In the immunosuppressed population, the spectrum of potential oral disease is even broader, encompassing candidiasis, necrotizing gingivitis, parotid gland enlargement, Kaposi’s sarcoma, oral warts and other diseases. Here, we used 454 pyrosequencing of bacterial 16S rRNA genes to examine the oral microbiome of saliva, mucosal and tooth samples from HIV-positive and negative children. Patient demographics and clinical characteristics were collected from a cross-section of patients undergoing routine dental care. Multiple specimens from different sampling sites in the mouth were collected for each patient. The goal of the study was to observe the potential diversity of the oral microbiota among individual patients, sample locations, HIV status and various dental characteristics. We found that there were significant differences in the microbiome among the enrolled patients, and between sampling locations. The analysis was complicated by uneven enrollment in the patient cohorts, with only five HIV-negative patients enrolled in the study and by the rapid improvement in the health of HIV-infected children between the time the study was conceived and completed. The generally good oral health of the HIV-negative patients limited the number of dental plaque samples that could be collected. We did not identify significant differences between well-controlled HIV-positive patients and HIV-negative controls, suggesting that well-controlled HIV-positive patients essentially harbor similar oral flora compared to patients without HIV. Nor were significant differences in the oral microbiota identified between different teeth or with different dental characteristics. Additional studies are needed to better

    Introduction With improved access to antiretroviral therapy (ART), HIV infection is becoming a chronic illness. Preliminary data suggest that HIV-infected children have a higher risk of disabilities, including hearing impairment, although data are sparse. This study aimed to estimate the prevalence and types of hearing loss in HIV-infected children in Lilongwe, Malawi. Methods This was a cross-sectional survey of 380 HIV-infected children aged 4–14 years attending ART clinic in Lilongwe between December 2013-March 2014. Data was collected through pediatric quality of life and sociodemographic questionnaires, electronic medical record review, and detailed audiologic testing. Hearing loss was defined as >20 decibels hearing level (dBHL) in either ear. Predictors of hearing loss were explored by regression analysis generating age- and sex-adjusted odds ratios. Children with significant hearing loss were fitted with hearing aids. Results Of 380 patients, 24% had hearing loss: 82% conductive, 14% sensorineural, and 4% mixed. Twenty-one patients (23% of those with hearing loss) were referred for hearing aid fitting. There was a higher prevalence of hearing loss in children with history of frequent ear infections (OR 7.4, 4.2–13.0) and ear drainage (OR 6.4, 3.6–11.6). Hearing loss was linked to history of WHO Stage 3 (OR 2.4, 1.2–4.5) or Stage 4 (OR 6.4, 2.7–15.2) and history of malnutrition (OR 2.1, 1.3–3.5), but not to duration of ART or CD4. Only 40% of caregivers accurately perceived their child’s hearing loss. Children with hearing impairment were less likely to attend school and had poorer emotional (p = 0.02) and school functioning (p = 0.04). Conclusions There is an urgent need for improved screening tools, identification and treatment of hearing problems in HIV-infected children, as hearing loss was common in this group and affected school functioning and quality of life. Clear strategies were identified for prevention and treatment, since most

    Objective: Several pieces of evidence indicate that HIV-infected adults undergo premature aging. The effect of HIV and antiretroviral therapy (ART) exposure on the aging process of HIV-infected children may be more deleterious since their immune system coevolves from birth with HIV. Design: Seventy-one HIV-infected (HIV+), 65 HIV-exposed-uninfected (HEU), and 56 HIV-unexposed-uninfected (HUU) children, all aged 0–5 years, were studied for biological aging and immune senescence. Methods: Telomere length and T-cell receptor rearrangement excision circle levels were quantified in peripheral blood cells by real-time PCR. CD4+ and CD8+ cells were analysed for differentiation, senescence, and activation/exhaustion markers by flow cytometry. Results: Telomere lengths were significantly shorter in HIV+ than in HEU and HUU children (overall, P < 0.001 adjusted for age); HIV+ ART-naive (42%) children had shorter telomere length compared with children on ART (P = 0.003 adjusted for age). T-cell receptor rearrangement excision circle levels and CD8+ recent thymic emigrant cells (CD45RA+CD31+) were significantly lower in the HIV+ than in control groups (overall, P = 0.025 and P = 0.005, respectively). Percentages of senescent (CD28−CD57+), activated (CD38+HLA-DR+), and exhausted (PD1+) CD8+ cells were significantly higher in HIV+ than in HEU and HUU children (P = 0.004, P < 0.001, and P < 0.001, respectively). Within the CD4+ cell subset, the percentage of senescent cells did not differ between HIV+ and controls, but programmed cell death receptor-1 expression was upregulated in the former. Conclusions: HIV-infected children exhibit premature biological aging with accelerated immune senescence, which particularly affects the CD8+ cell subset. HIV infection per se seems to influence the aging process, rather than exposure to ART for prophylaxis or treatment. PMID:26990630

    It is estimated that the number of HIV infected children globally has increased from 1.6 million in 2001 to 3.3 million in 2012. The number of children below 15 years of age living with HIV has increased worldwide. Published data from recent studies confirmed dramatic survival benefit for infants started anti-retroviral therapy (ART) as early as possible after diagnosis of HI. Early confirmation of HIV diagnosis is required in order to identify infants who need immediate ART. WHO has designed recommendations to improve programs for both early diagnoses of HIV infection and considering ART whenever indicated? It is strongly recommended that HIV virologocal assays for diagnosis of HIV have sensitivity of at least 95% and ideally greater than 98% and specificity of 98% or more under standardized and validated conditions. Timing of virological testing is also important. Infants infected at or around delivery may take short time to have detectable virus. Therefore, sensitivity of virological tests is lower at birth. In utero HIV infection, HIV DNA or RNA can be detected within 48 h of birth and in infants with peripartum acquisition it needs one to two weeks. Finally it is emphasized that all laboratories performing HIV tests should follow available services provided by WHO or CDC for quality assurance programs. Both clinicians and staffs providing laboratory services need regular communications, well-defined SOPs and nationally validated algorithms for optimal use of laboratory tests. Every country should use assays that have been validated by national reference laboratory. PMID:27499768

Early confirmation of HIV diagnosis is required in order to identify infants who need immediate ART. WHO has designed recommendations to improve programs for both early diagnoses of HIV infection and considering ART whenever indicated? It is strongly recommended that HIV virologocal assays for diagnosis of HIV have sensitivity of at least 95% and ideally greater than 98% and specificity of 98% or more under standardized and validated conditions. Timing of virological testing is also important. Infants infected at or around delivery may take short time to have detectable virus. Therefore, sensitivity of virological tests is lower at birth. In utero HIV infection, HIV DNA or RNA can be detected within 48 h of birth and in infants with peripartum acquisition it needs one to two weeks. Finally it is emphasized that all laboratories performing HIV tests should follow available services provided by WHO or CDC for quality assurance programs. Both clinicians and staffs providing laboratory services need regular communications, well-defined SOPs and nationally validated algorithms for optimal use of laboratory tests. Every country should use assays that have been validated by national reference laboratory.

    Therapeutic immunizations in HIV infection may boost immunity during antiretroviral treatment. We report on the first therapeutic vaccine trial in Uganda, Africa. This open label Phase I trial was designed to assess the safety, tolerability and immunogenicity of a therapeutic HIV-1 vaccine candidate. Thirty HIV positive volunteers receiving a stable regimen of antiretroviral therapy with CD4 counts > 400 were recruited for the safety evaluation of LFn-p24C, a detoxified anthrax-derived polypeptide fused to the subtype C HIV gag protein p24. The vaccine was well tolerated and HIV RNA levels remained undetectable following three immunizations. CD4 counts in vaccine recipients were significantly higher compared to the control individuals after 12 months. HIV-specific responses were associated with higher gain in CD4 counts following LFn-p24C immunizations. Volunteers were subsequently asked to undergo a 30-day period of observed treatment interruption. 8/24 (30%) individuals showed no evidence of viral rebound during treatment interruption. All demonstrated prompt suppression of viral load following resumption of ART. Our data demonstrates the safety of LFn-p24C and suggests that adjunct therapeutic immunization may benefit select individuals in further boosting an immune response. PMID:21211581

    Most patients failing antiretroviral treatment in Uganda continue to fail their treatment regimen even if a dominant drug-resistant HIV-1 genotype is not detected. In a recent retrospective study, we observed that approximately 30% of HIV-infected individuals in the Joint Clinical Research Centre (Kampala, Uganda) experienced virologic failure with a susceptible HIV-1 genotype based on standard Sanger sequencing. Selection of minority drug-resistant HIV-1 variants (not detectable by Sanger sequencing) under antiretroviral therapy pressure can lead to a shift in the viral quasispecies distribution, becoming dominant members of the virus population and eventually causing treatment failure. Here, we used a novel HIV-1 genotyping assay based on deep sequencing (DeepGen) to quantify low-level drug-resistant HIV-1 variants in 33 patients failing a first-line antiretroviral treatment regimen in the absence of drug-resistant mutations, as screened by standard population-based Sanger sequencing. Using this sensitive assay, we observed that 64% (21/33) of these individuals had low-frequency (or minority) drug-resistant variants in the intrapatient HIV-1 population, which correlated with treatment failure. Moreover, the presence of these minority HIV-1 variants was associated with higher intrapatient HIV-1 diversity, suggesting a dynamic selection or fading of drug-resistant HIV-1 variants from the viral quasispecies in the presence or absence of drug pressure, respectively. This study identified low-frequency HIV drug resistance mutations by deep sequencing in Ugandan patients failing antiretroviral treatment but lacking dominant drug resistance mutations as determined by Sanger sequencing methods. We showed that these low-abundance drug-resistant viruses could have significant consequences for clinical outcomes, especially if treatment is not modified based on a susceptible HIV-1 genotype by Sanger sequencing. Therefore, we propose to make clinical decisions using more

    The secrecy surrounding the disease of parents and children infected with HIV leads to psychic and affective isolation and difficulties of communication within the family. Psychological management may possibly help to resolve the problem of secrecy between parents and children. We analyzed the organization and dynamics of the secret surrounding children contaminated by their mothers. The analysis was prospective and was based on semi-directive interviews and drawings. We followed up, over a period of two years, ten children (mean age: 4 years, range: 4 months to 12 years) with different ethnic and socio economic backgrounds. In each family, the child was the target of the secret, the pediatrician the guardian, and the mother (or her substitute) the keeper. The organization of the secret around the other potential guardians varied from one family to another. Two modes of intra-family communication were observed: the secret (reserved for the youngest children) and the tacit. One child suffered from a disorder related to the secret, the others had depressive and reactional symptoms. At the end of the study, the manner of approaching, and especially dealing with, the question of the secret had changed appreciably in each family: disclosure to the family circle (three cases), passage of the child from the secret to the tacit (two cases), and easier questioning of the pediatrician in all of the cases. Nonetheless, in no case had the secret been completely lifted for the child. Four children asked to continue psychological management. The changes in the dynamics of the secret and the appeasement observed in the families suggest that psychotherapeutic aid should be offered to families where a child has been contaminated with HIV by the mother.

    High adherence is critical for achieving clinical benefits of HIV antiretroviral therapy (ART) and particularly challenging for children. We conducted 35 qualitative interviews with caregivers of HIV-infected Ugandan children who were followed in a longitudinal study of real-time ART adherence monitoring; 18 participants had undetectable HIV RNA, while 17 had detectable virus. Interviews blinded to viral suppression status elicited information on adherence experiences, barriers and facilitators to adherence, and social support. Using an inductive content analytic approach, we identified ‘lack of resources,’ ‘Lazarus effect,’ ‘caregiver's sense of obligation and commitment,’ and ‘child's personal responsibility’ as categories of influence on adherence, and defined types of caregiver social support. Among children with viral suppression, high hopes for the child's future and ready access to private instrumental support appeared particularly important. These findings suggest clinical counseling should explore caregivers' views of their children's futures and ability to access support in overcoming adherence barriers. PMID:25323679

    The laboratory diagnosis of HIV-1 infection in newborns should be carried out using virological methods, viral isolation or molecular methods for the detection of proviral DNA by PCR. Serological methods have poor sensitivity in the first months of life because the IgG of the seropositive mother crosses the placenta. Once HIV-1 infection is diagnosed, other assays are available which indicate the clinical progression of the infection, the genetic variability of the virus, its biological behavior and sensitivity to different antiretroviral medications. These studies can be used independently of the clinical manifestations in order to assess disease progression. Different immunological markers and virological markers of disease progression have been described, but the CD4+ T lymphocyte count is used routinely as an immunological marker and as a virological marker of the virus load. In HIV-1 newborns and children, the largest decrease in the number of CD4+ T lymphocytes is due to the combined effect of infection progression and a natural decrease in CD4+ T lymphocytes with age. In newborns, low viral load levels suggest that the infection was acquired shortly before birth or that maternal and/or placental factors inhibited viral replication before birth, or that the child was infected at birth. In children, viral loads are greater than in adult patients during the primary infection and throughout their evolution. Because of advances in the treatment of HIV-1 infection, the study of resistance to antiretroviral agents by phenotypical and genotypical methods is important. Increased viral load suggests the loss of effectiveness of a treatment and should be monitored. PMID:9675394

    Introduction As highly active antiretroviral therapy (HAART) transforms human immunodeficiency virus (HIV) into a manageable chronic disease, new challenges are emerging in treating children born with HIV, including a number of risks to their physical and psychological health due to HIV infection and its lifelong treatment. Methods We conducted a literature review to evaluate the evidence on the physical and psychological effects of perinatal HIV (PHIV+) infection and its treatment in the era of HAART, including major chronic comorbidities. Results and discussion Perinatally infected children face concerning levels of treatment failure and drug resistance, which may hamper their long-term treatment and result in more significant comorbidities. Physical complications from PHIV+ infection and treatment potentially affect all major organ systems. Although treatment with antiretroviral (ARV) therapy has reduced incidence of severe neurocognitive diseases like HIV encephalopathy, perinatally infected children may experience less severe neurocognitive complications related to HIV disease and ARV neurotoxicity. Major metabolic complications include dyslipidaemia and insulin resistance, complications that are associated with both HIV infection and several ARV agents and may significantly affect cardiovascular disease risk with age. Bone abnormalities, particularly amongst children treated with tenofovir, are a concern for perinatally infected children who may be at higher risk for bone fractures and osteoporosis. In many studies, rates of anaemia are significantly higher for HIV-infected children. Renal failure is a significant complication and cause of death amongst perinatally infected children, while new data on sexual and reproductive health suggest that sexually transmitted infections and birth complications may be additional concerns for perinatally infected children in adolescence. Finally, perinatally infected children may face psychological challenges, including

    Introduction: Previous unblinded trials have shown increased malaria among HIV-infected adults on antiretroviral therapy (ART) who stop cotrimoxazole (CTX) prophylaxis. We investigated the effect of stopping CTX on malaria in HIV-infected adults on ART in a double-blind, placebo-controlled trial. Methods: HIV-infected Ugandan adults stable on ART and CTX with CD4+ cell count at least 250 cells/μl were randomized (1 : 1) to continue CTX or stop CTX and receive matching placebo (COSTOP trial; ISRCTN44723643). Clinical malaria was defined as fever and a positive blood slide, and considered severe if a participant had at least one clinical or laboratory feature of severity or was admitted to hospital. Malaria incidence and rate ratios were estimated using random effects Poisson regression, accounting for multiple episodes. Results: A total of 2180 participants were enrolled and followed for a median of 2.5 years; 453 malaria episodes were recorded. Malaria incidence was 9.1/100 person-years (pyrs) [95% confidence interval (CI) = 8.2–10.1] and was higher on placebo (rate ratio 3.47; CI = 2.74–4.39). Malaria in the placebo arm decreased over time; although incidence remained higher than in the CTX arm, the difference between arms reduced slightly (interaction P value = 0.10). Fifteen participants experienced severe malaria (<1%); overall incidence was 0.30/100 pyrs (CI = 0.18–0.49). There was one malaria-related death (CTX arm). Conclusion: HIV-infected adults – who are stable on ART and stop prophylactic CTX – experience more malaria than those that continue, but this difference is less than has been reported in previous trials. Few participants had severe malaria. Further research might be useful in identifying groups that can safely stop CTX prophylaxis. PMID:26558729

In multivariable analysis, food insufficiency [adjusted odds ratio (aOR) 0.38, 95% confidence interval (CI): 0.16 to 0.91], higher pretreatment HIV-1 RNA (aOR 0.55 per 10-fold increase, 95% CI: 0.37 to 0.82), and lopinavir/ritonavir versus efavirenz (aOR 0.49, 95% CI: 0.24 to 0.96) were associated with lower odds of sustained viral suppression. Interventions to address food security may improve virologic outcomes among HIV-infected women. PMID:26397935

    The global epidemic of HIV infection remains appalling. By 2001, there were an estimated 1.4 million HIV-infected children, with 4.5 million deaths. In the UK, paediatric cases are clustered around population centres where there are high concentrations of infected immigrant adults, and to a lesser extent, areas where IV drug abuse is common. The highest incidence remains in London and the southeast. With the national redistribution of immigrant and refugee families, any doctor in any specialty may expect to be involved with children who are HIV positive, or have clinical AIDS. The majority of children are infected vertically, i.e. infection of the infant from an infected mother in the pre-, peri-, or post-natal periods. Rates of transmission vary from 15-20% in the developed countries. Children with HIV infection may have their primary presentation to ENT doctors, who should have appropriate thresholds for suspecting the diagnosis. The most common presenting features include persistent generalised lymphadenopathy, hepatosplenomegaly, chronic/recurrent diarrhoea, poor growth, and fever. Fifteen to twenty percent of untreated children will present with an AIDS-defining illness by 12 months, typically with Pneumocystis pneumonia at approximately 3-4 months of age. Seventy percent of perinatally infected children will exhibit some signs or symptoms by 12 months Without treatment, the median age to progression to AIDS is approximately 6 years, and 25-30% will have died by this age. The median age of death is approximately 9 years. Children may also present with repeated/unusual ear infections, sinus disease (inc. mastoiditis), tonsillitis, orbital/peri-orbital cellulitis, oral candidiasis, and dental infections. Infections with streptococcus pneumoniae and group A streptococcus are common, and often progress to severe systemic infection with an appreciable mortality. Infections may be due to unusual pathogens such as Pseudomonas, 'typical' and atypical Mycobacteria

    Fourteen asymptomatic HIV-infected Zairian children under 2 years of age displayed social and motor developmental deficits on the Denver Developmental Screening Test when compared with 20 HIV-negative cohorts born to HIV-infected mothers and 16 control children. In a second study, 11 infected children over 2 years of age had sequential motor and visual-spatial memory deficits on the Kaufman Assessment Battery for Children and motor development deficits on the Early Childhood Screening Profiles. HIV infection affects central nervous system structures mediating motor and spatial memory development, even in seemingly asymptomatic children. Furthermore, maternal HIV infection compromises the labor-intensive provision of care in the African milieu and undermines global cognitive development in even uninfected children. PMID:7737068

    We evaluated the acceptability and use of macronutrient supplementation among HIV-infected pregnant Ugandan women receiving antiretroviral therapy in a clinical study (NCT 00993031). We first conducted formative research among 56 pregnant and lactating women to select a supplement regimen. Acceptability and use of the supplementation regimen (35 sachets of lipid-based nutrient supplements (LNS) and 4 or 6 kg of instant soy porridge for the household provided monthly) were evaluated among 87 pregnant women. Organoleptic assessments of LNS were favorable. Participants reported consuming LNS a mean of 6.1 days per week, and adherence to recommended consumption behaviors (e.g. frequency, quantity, not sharing) was >80 %. Few women reported negative social consequences of supplementation. The majority of participants also consumed most of the porridge intended for the household. In sum, LNS was acceptable and used regularly. Larger studies to evaluate physical and psychosocial consequences of LNS during pregnancy among HIV-infected women are warranted. PMID:25416075

    Tenofovir disoproxil fumarate (TDF) is approved by the Food and Drug Administration for use in children ages 2 years and older and is recommended by the World Health Organization for use as a preferred first-line nucleotide reverse transcriptase inhibitor in adults and adolescents ages 10 years and older. The simplicity of once daily dosing, few metabolic side effects and efficacy against hepatitis B virus make TDF suitable for use in a large scale program. Unlike thymidine analoge nucleoside reverse transcriptase inhibitors (NRTIs); tenofovir does not induce multi-NRTI resistance mutations, so more NRTI options are available for future second-line-regimens. Fixed-dose combinations of TDF with other ARVs as a single tablet regimen are now widely available for adults and adolescents, but none are available for young children. Current information on TDF including the pharmacokinetics, safety and tolerability in children and adolescents was reviewed. A dosing regimen according to body-weight-band has been established for pediatric use. Safety concerns of TDF mainly relate to its effects on renal function and bone mineral density. Regular monitoring of renal function in high-risk patients, including those on other nephrotoxic drugs, may be warranted to detect adverse renal effects. Long-term-data on renal and bone outcomes among HIV-infected children is needed. Lessons learned from clinical studies will help clinicians balance the risks and benefits of TDF and design appropriate antiretroviral regimens for children in different circumstances. PMID:25247583

    Although human papillomavirus (HPV) infections are common in HIV-infected adults, little is known about children. Our objective was to examine the prevalence of and risks for HPV of the oral mucosal and external genital areas in nonsexually active (NSA) perinatally (P) HIV+ children and compare with HIV-exposed but uninfected (HEU) children. A convenience sample attending a pediatric clinic were enrolled. Samples for HPV were obtained from the oral and anogenital areas and tested for one of 37 HPV types. The mean age of the 48 PHIV+ children was 14.3±3.9 years vs. 6.2±4.8 for the 52 HEU (p<0.001). Of the 23 PHIV+ girls, 30.4% had anogenital and 17% had oral HPV, and of the 27 HEU girls, 2 (7.4%) anogenital and 0 had oral HPV. Of the boys, 4/23 (17.4%) and 1/25 (4%) PHIV+ had anogenital and oral HPV, respectively, and 3/24 (12.5%) and 1/25 (4%) HEU had anogenital and oral HPV, respectively. Rates of HPV did not differ by age among the PHIV+, whereas older HEU were more likely to have HPV than younger HEU (p=0.07). This large age gap precluded statistical comparison by HIV status. The presence of HPV in NSA PHIV+ children may have implications regarding HPV vaccination efficacy. PMID:24460009

    Background Cardiac involvement in HIV infected children has been frequently reported, but whether this is due to HIV infection itself or to antiretroviral treatment (ART) is unknown. Methods This cross sectional study involved 114 vertically-acquired HIV-infected (56 ART-naive, 58 ART-exposed) and 51 healthy children in Jakarta, Indonesia. Echocardiography was performed to measure dimensions of the left ventricle (LV) and systolic functions. We applied general linear modeling to evaluate the associations between HIV infection/treatment status and cardiac parameters with further adjustment for potential confounders or explanatory variables. Findings are presented as (adjusted) mean differences between each of the two HIV groups and healthy children, with 95% confidence intervals and p values. Results Compared to healthy children, ART-naïve HIV-infected children did not show significant differences in age-and-height adjusted cardiac dimensions apart from larger LV internal diameter (difference 2.0 mm, 95%CI 0.2 to 3.7), whereas ART exposed HIV infection showed thicker LV posterior walls (difference = 1.1 mm, 95%CI 0.5 to 1.6), larger LV internal diameter (difference = 1.7 mm, 95%CI 0.2 to 3.2) and higher LV mass (difference = 14.0 g, 7.4 to 20.5). With respect to systolic function, reduced LV ejection fraction was seen in both ART-naïve HIV infected (adjusted difference = -6.7%, -11.4 to -2.0) and, to a lesser extent, in ART-exposed HIV infected children (difference = -4.5%, -8.5 to -0.4). Inflammation level seemed to be involved in most associations in ART-exposed HIV-infected, but few, if any, for decreased function in the ART-naive ones, whereas lower hemoglobin appeared to partially mediate chamber dilation in both groups and reduced function, mainly in ART-exposed children. Conclusions ART-naive HIV infected children have a substantial decrease in cardiac systolic function, whereas the ART-exposed have thicker ventricular walls with larger internal diameter

    Objective The detection of urinary lipoarabinomannan (LAM), a mycobacterial cell wall component, is used to diagnose tuberculosis (TB). How LAM enters the urine is not known. To investigate if urinary LAM-positivity is the result of renal TB infection we correlated the outcomes of urinary LAM-antigen testing to renal histology in an autopsy cohort of hospitalized, Ugandan, HIV-infected adults. Methods We performed a complete autopsy, including renal sampling, in HIV-infected adults that died during hospitalization after written informed consent was obtained from the next of kin. Urine was collected postmortem through post-mortem catheterisation or by bladder puncture and tested for LAM with both a lateral flow assay (LFA) and an ELISA assay. Two pathologists assessed the kidney histology. We correlated the LAM-assay results and the histology findings. Results Of the 13/36 (36%) patients with a positive urinary LAM ELISA and/or LFA, 8/13 (62%) had renal TB. The remaining 5 LAM-positive patients had disseminated TB without renal involvement. Of the 23 LAM-negative patients, 3 had disseminated TB without renal involvement. The remaining LAM-negative patients had no TB infection and died mostly of fungal and bacterial infections. LAM LFA had a sensitivity of 81% and specificity of 100% to diagnose TB at any location, and the LAM ELISA a sensitivity of 63% and a specificity of 100%. 54% (7/13) LAM LFA-positive patients were not on anti-TB treatment at the time of death. Conclusion Renal TB infection explained LAM-positivity in the majority of patients. Patients with disseminated TB without renal involvement can also be diagnosed with LAM. This suggests that other mechanisms that lead to urinary LAM-positivity exist in a minority of patients. PMID:25897661

    Background Major depressive disorder is highly prevalent among HIV-infected persons, and depression symptom severity improves during the course of HIV antiretroviral therapy (ART). The potential biologic pathways explaining these phenomena remain unclear. We investigated the extent to which ART-mediated suppression of the kynurenine pathway of tryptophan catabolism (via indoleamine 2,3-dioxygenase-1 and potentially other sources) may correlate with improvements in depression symptom severity in this setting. Method We used the first year of data from the Uganda AIDS Rural Treatment Outcomes Study, a prospective cohort of 504 HIV-infected individuals initiating their first ART regimen in rural Uganda. We fitted random-effects regression models to estimate the associations between plasma tryptophan, plasma kynurenine, dietary diversity, and self-reported depression symptom severity. Results Greater depressive symptoms were associated with both lower plasma tryptophan and higher plasma kynurenine/tryptophan (KT) ratio over 12-month follow-up. In multivariable-adjusted models, declines in KT ratio and increases in plasma tryptophan levels partially explained ART-mediated improvements in depressive symptom severity. The association between KT ratio and depression symptom severity was stronger among persons with protein-deficient diets than among those with protein-rich diets. Conclusions IDO-mediated tryptophan catabolism may contribute to depression symptom severity among HIV-infected individuals, particularly among those with poor dietary protein intake. ART-mediated improvements in depressive symptom severity may also be at least partially mediated by immunologic mechanisms. Interventions to reduce immune activation, and dietary protein supplementation, may be promising strategies to further reduce depression in this setting. PMID:24220289

    Renewed efforts to provide proper nutritional care are essential for appropriate pediatric HIV management. Current studies support the use of vitamin A and macronutrients that increase caloric and protein intake. With additional research on key issues such as the needed composition and timing for nutritional supplementation, we can determine the best strategies to support the growth and development of HIV-infected children in resource-limited settings. Malnutrition among children is common in the resource-limited settings where HIV infection is most prevalent. While malnutrition is associated with higher morbidity and mortality for HIV-infected children, there is only limited evidence to guide the use of nutritional support for HIV-infected children. The best studied is vitamin A, which is associated with improved mortality and clinical outcomes. Zinc and multivitamin supplementation have not consistently been associated with clinical benefits. Limited research suggests macronutrient supplementation, which typically uses enriched formulas or foods, improves key anthropometrics for HIV-infected children, but the optimal composition of nutrients for supplementation has not been determined. More research is needed to understand the most efficient and sustainable ways to ensure adequate nutrition in this vulnerable population. PMID:25371264

    HIV infection can contribute to disturbances in both linear growth and weight gain in early childhood, with disturbances often apparent as early as 3 mo of age. There is little evidence for a difference in the early growth of HIV-exposed but uninfected children compared to healthy controls. Owing to the close association of growth with immune function and clinical progression, an understanding of growth patterns may be an important tool to ensure the provision of appropriate care to HIV-infected and exposed children. Timely growth monitoring may be used to improve the clinical course and quality of life of these children. PMID:19519675

    Background Treatment of HIV/malaria-coinfected patients with antiretroviral therapy (ART) and artemisinin-based combination therapy has potential for drug interactions. We investigated the pharmacokinetics of artemether, dihydroartemisinin and lumefantrine after administration of a single dose of 80/480 mg of artemether/lumefantrine to HIV-infected adults, taken with and without lopinavir/ritonavir. Methods A two-arm parallel study of 13 HIV-infected ART-naive adults and 16 HIV-infected adults stable on 400/100 mg of lopinavir/ritonavir plus two nucleoside reverse transcriptase inhibitors (ClinicalTrials.gov, NCT 00619944). Each participant received a single dose of 80/480 mg of artemether/lumefantrine under continuous cardiac function monitoring. Plasma concentrations of artemether, dihydroartemisinin and lumefantrine were measured. Results Co-administration of artemether/lumefantrine with lopinavir/ritonavir significantly reduced artemether maximum concentration (Cmax) and area under the concentration–time curve (AUC) [median (range): 112 (20–362) versus 56 (17–236) ng/mL, P = 0.03; and 264 (92–1129) versus 151 (38–606) ng · h/mL, P < 0.01]. Dihydroartemisinin Cmax and AUC were not affected [66 (10–111) versus 73 (31–224) ng/mL, P = 0.55; and 213 (68–343) versus 175 (118–262) ng · h/mL P = 0.27]. Lumefantrine Cmax and AUC increased during co-administration [2532 (1071–5957) versus 7097 (2396–9462) ng/mL, P < 0.01; and 41 119 (12 850–125 200) versus 199 678 (71 205–251 015) ng · h/mL, P < 0.01]. Conclusions Co-administration of artemether/lumefantrine with lopinavir/ritonavir significantly increases lumefantrine exposure, but decreases artemether exposure. Population pharmacokinetic and pharmacodynamic trials will be highly valuable in evaluating the clinical significance of this interaction and determining whether dosage modifications are indicated.

    This research aims to determine the relationship between the prevalence of caries and clinical and immunological classification in HIV-infected children. Ninety-two outpatients (42 male and 50 female subjects) with definitive diagnosis of HIV infection took part in this research. The patients were examined in order to determine the prevalence of caries (dmf and DMFT indexes), and medical data were collected from their medical records. The mean age of the subjects was 5.77 years. Although no statistical differences were found, young patients (up to 5 years old) had more caries when they were more clinically and immunologically compromised. The same fact was observed regarding older children. PMID:11705204

    Parvovirus 4 (PARV4) has been associated with HIV infection in adults. We examined plasma samples from 46 HIV-infected 0-year-old to 16-year-old children for the presence of PARV4. Four children (8.7%) had detectable PARV4 IgG and 1 had IgM. The result of PARV4 polymerase chain reaction was found to be negative in all patients. PARV4 seropositivity was associated with low CD4 count but not with HIV viral load. PMID:25545184

    Early cardiovascular disease is a major concern for ART-suppressed vertically HIV-infected children; however, evidence is lacking regarding specific preventive measures. In this study, a complete panel of biomarkers was determined together with carotid intima-media thickness (IMT), in a cohort of 64 HIV-infected children and 30 controls. Mean age of participants was 14.1±5 years. HIV-infected patients showed normal lipid profile, with only slightly higher triglycerides, and no differences between groups were found regarding IMT. HIV-infected patients displayed higher levels of soluble CD14 (sCD14) and soluble vascular cell adhesion molecule-1 (sVCAM) (all p<0.05). However, levels of C-reactive protein, interleukin-6, myeloperoxidase, monocyte chemoattractant protein-1, P-selectin and tissue plasminogen activator were similar between groups. Vertically HIV-infected subjects on ART with no significant metabolic disturbances displayed increased sCD14 and sVCAM but not up-regulation of proinflammatory pathways. Larger studies are warranted to assess the impact of a strict metabolic control on cardiovascular risk and to define specific cardiovascular disease preventive strategies in this population.

    Background: Poor nutrition has been associated with impaired immunity and accelerated disease progression in HIV-infected children. The aim of this study was to quantify the levels of nutrient intake in HIV-infected children and compare these to standard recommendations. Methods: We surveyed HIV-infected Tanzanian children enrolled in a pediatric care program that provided routine nutritional counseling and vitamin supplementation. We obtained anthropometric measurements and determined 24-hour macronutrient and micronutrient intakes and food insecurity. Values were compared to recommended nutrient intakes based on age and gender. Results: We interviewed 48 pairs of children and their caregiver(s). The age of the child ranged from 2-14 years; median age 6 and 60% female. The median weight-for-height z-score for children ≤ 5 years was 0.69 and BMI-for-age z-scores for children >5 was -0.84. Macronutrient evaluation showed that 29 (60%) children were deficient in dietary intake of energy; deficiency was more common in older children (p=0.004). Micronutrient evaluation shows that over half of study subjects were deficient in dietary intake of vitamin A, vitamin D, vitamin E, thiamine, riboflavin, niacin, folate, vitamin B12, and calcium. Food insecurity was reported by 20 (58%) caregivers. Conclusions and Public Health Implications: The diets of many HIV-infected children at a specialized treatment center in Tanzania do not meet recommended levels of macro-and micro-nutrients. Food insecurity was a contributory factor. Enhanced dietary counseling and provision of macro- and micro-nutrient supplements will be necessary to achieve optimal nutrition for most HIV-infected children in resource-poor regions.

    Background We aimed to compare the steady-state pharmacokinetic parameters and tolerability of Triomune 40® (stavudine 40 mg, lamivudine 150 mg and nevirapine 200 mg) and branded formulations of these drugs in HIV-infected Ugandans. Methods This includes a randomized, open-label, cross-over study of HIV-infected patients stable on therapy for 1 month. Patients were randomized to generic or branded formulation. Plasma pharmacokinetics were assessed after 1 month. The following day, alternate formulation was administered, and 1 month later, drug pharmacokinetics were re-assessed. Plasma pharmacokinetics were determined using HPLC–UV detection. Similarity between steady-state pharmacokinetic parameters was assessed using the US Food and Drug Administration standards for bioequivalency testing. Tolerability was assessed using questionnaires. Results Sixteen (10 females) patients completed the study. Median (IQR) age, weight and CD4 count were 37 (33.7–40) years, 65 (63.4–66) kg and 292 (220.7–344.5) cells/mm3, respectively. All patients received co-trimoxazole. The geometric mean ratio (90% CI) for stavudine, lamivudine and nevirapine was 0.92 (0.78–1.08), 1.11 (0.95–1.30) and 0.84 (0.64–1.11), respectively, for Cmax, and 0.83 (0.70–0.97), 1.06 (0.94–1.20) and 0.88 (0.71–1.10), respectively, for AUC. Stavudine plasma concentrations were significantly lower for the generic formulation. Pharmacokinetic parameter inter-individual variability ranged from 29% to 99%. There were no differences in tolerability for the two formulations. Conclusions Pharmacokinetic profiles of generic and branded drugs were similar. Differences particularly with regard to stavudine were demonstrated. Surveillance of the quality of generic antiretroviral drugs in the target populations is needed. Capacity building for pharmacokinetic research in resource-limited settings is a priority. PMID:18641036

    Objective To evaluate the occurrence, clinical presentations and diagnostic methods for tuberculosis (TB) in a cohort of HIV-infected infants, children and adolescents from Latin America. Methods A retrospective analysis of children with TB and HIV was performed within a prospective observational cohort study conducted at multiple clinical sites in Latin America. Results Of 1114 HIV-infected infants, children, and adolescents followed from 2002-2011, 69 that could be classified as having confirmed or presumed TB were included in this case series; 52.2% (95% CI: 39.8-64.4%) had laboratory-confirmed TB, 15.9% (95% CI: 8.2-26.7%) had clinically-confirmed disease and 31.9% (95% CI: 21.2-44.2%) had presumed TB. Sixty-six were perinatally HIV-infected. Thirty-two (61.5%) children had a history of contact with an adult TB case; however information on exposure to active TB was missing for 17 participants. At the time of TB diagnosis, 39 were receiving antiretroviral therapy. Sixteen of these cases may have represented immune reconstitution inflammatory syndrome. Conclusions Our study emphasizes the need for adequate contact tracing of adult TB cases and screening for HIV or TB in Latin American children diagnosed with either condition. Preventive strategies in TB-exposed, HIV-infected children should be optimized. PMID:25307683

    More than 90% of the estimated 3.2 million children with HIV worldwide, at the end of 2013, were living in sub-Saharan Africa. The management of these children was still difficult in 2014 despite the progress in access to antiretroviral drugs. A great number of HIV-infected children are not diagnosed at 6 weeks and start antiretroviral treatment late, at an advanced stage of HIV disease complicated by other comorbidities such as malnutrition. Malnutrition is a major problem in the sub-Saharan Africa global population; it is an additional burden for HIV-infected children because they do not respond as well as non-infected children to the usual nutritional care. HIV infection and malnutrition interact, creating a vicious circle. It is important to understand the relationship between these 2 conditions and the effect of antiretroviral treatment on this circle to taking them into account for an optimal management of pediatric HIV. An improved monitoring of growth during follow-up and the introduction of a nutritional support among HIV-infected children, especially at antiretroviral treatment initiation, are important factors that could improve response to antiretroviral treatment and optimize the management of pediatric HIV in resource-limited countries.

    Background In sub-Saharan Africa many children live in extreme poverty and experience a burden of illness and disease that is disproportionately high. The emergence of HIV and AIDS has only exacerbated long-standing challenges to improving children’s health in the region, with recent cohorts experiencing pediatric AIDS and high levels of orphan status, situations which are monitored globally and receive much policy and research attention. Children’s health, however, can be affected also by living with HIV-infected adults, through associated exposure to infectious diseases and the diversion of household resources away from them. While long recognized, far less research has focused on characterizing this distinct and vulnerable population of HIV-affected children. Methods Using Demographic and Health Survey data from 23 countries collected between 2003 and 2011, we estimate the percentage of children living in a household with at least one HIV-infected adult. We assess overlaps with orphan status and investigate the relationship between children and the adults who are infected in their households. Results The population of children living in a household with at least one HIV-infected adult is substantial where HIV prevalence is high; in Southern Africa, the percentage exceeded 10% in all countries and reached as high as 36%. This population is largely distinct from the orphan population. Among children living in households with tested, HIV-infected adults, most live with parents, often mothers, who are infected; nonetheless, in most countries over 20% live in households with at least one infected adult who is not a parent. Conclusion Until new infections contract significantly, improvements in HIV/AIDS treatment suggest that the population of children living with HIV-infected adults will remain substantial. It is vital to on-going efforts to reduce childhood morbidity and mortality to consider whether current care and outreach sufficiently address the distinct

    The objective of this study was to estimate the protective effect of Bacille Calmette-Guérin (BCG) vaccine against tuberculosis among (predominantly immunodeficient) HIV-infected children in Angola. A hospital-based case-control study was conducted with 230 cases, children coinfected with tuberculosis, and 672 controls, HIV-infected children from the same hospital, aged 18 months to 13 years. The presence of a vaccination scar was taken as a proxy marker for BCG vaccination. The crude effectiveness was 8% (95% CI: −26 to 32) and the adjusted effectiveness was 30% (95% CI: −75 to 72). The present study suggests that BCG does not have a protective effect against tuberculosis among immunodeficient HIV-infected children. Since BCG is no longer given to HIV-infected children, the study may not be replicated. Accepting that these findings should be considered with caution, they are nonetheless likely to be the last estimate of BCG efficacy in a sufficiently powered study. PMID:26221585

    Despite treatment with combination antiretroviral therapy (cART), cognitive impairment is still observed in perinatally HIV-infected children. We aimed to evaluate potential underlying cerebral injury by comparing neurometabolite levels between perinatally HIV-infected children and healthy controls. This cross-sectional study evaluated neurometabolites, as measured by Magnetic Resonance Spectroscopy (MRS), in perinatally HIV-infected children stable on cART (n = 26) and healthy controls (n = 36).Participants were included from a cohort of perinatally HIV-infected children and healthy controls, matched group-wise for age, gender, ethnicity, and socio-economic status. N-acetylaspartate (NAA), glutamate (Glu), myo-inositol (mI), and choline (Cho) levels were studied as ratios over creatine (Cre). Group differences and associations with HIV-related parameters, cognitive functioning, and neuronal damage markers (neurofilament and total Tau proteins) were determined using age-adjusted linear regression analyses.HIV-infected children had increased Cho:Cre in white matter (HIV-infected = 0.29 ± 0.03; controls = 0.27 ± 0.03; P value = 0.045). Lower nadir CD4+ T-cell Z-scores were associated with reduced neuronal integrity markers NAA:Cre and Glu:Cre. A Centers for Disease Control and Prevention (CDC) stage C diagnosis was associated with higher glial markers Cho:Cre and mI:Cre. Poorer cognitive performance was mainly associated with higher Cho:Cre in HIV-infected children, and with lower NAA:Cre and Glu:Cre in healthy controls. There were no associations between neurometabolites and neuronal damage markers in blood or CSF.Compared to controls, perinatally HIV-infected children had increased Cho:Cre in white matter, suggestive of ongoing glial proliferation. Levels of several neurometabolites were associated with cognitive performance, suggesting that MRS may be a useful method to assess cerebral changes potentially linked to cognitive outcomes

    From a social ecological perspective, this study examined the effects of stigma (societal level), trusting relationships with current caregivers (familial level), and self-esteem (individual level) on future orientation of children affected by HIV infection and AIDS. Comparing self-report data from 1221 children affected by parental HIV infection and AIDS and 404 unaffected children, affected children reported greater stigma and lower future orientation, trusting relationships, and self-esteem. Based on structural equation modeling, stigma experiences, trusting relationships, and self-esteem had direct effects on future orientation, with self-esteem and trusting relationships partially mediating the effect of stigma experiences on children's future orientation. Implications are discussed. PMID:25370572

    Resistance to antiretroviral drugs is an increasingly prevalent challenge affecting both the adult and pediatric HIV-infected populations. Though data on the safety, pharmacokinetics, and efficacy of newer antiretroviral agents in children typically lags behind adult data, newer agents are becoming available for use in HIV-infected children who are failing to respond to or are experiencing toxicities with traditional antiretroviral regimens. Integrase strand transfer inhibitors are one such new class of antiretrovirals. Raltegravir has been US Food and Drug Administration (FDA) approved for use in patients over the age of 4 weeks. Elvitegravir is a second member of this class, and has the potential for use in children but does not yet have a Pediatric FDA indication. Dolutegravir, a second-generation integrase inhibitor, is approved for those older than 12 years. This review summarizes the use of integrase inhibitors in children and adolescents, and highlights the results of recent clinical trials. PMID:26242765

    More than one fourth of children of HIV-infected mothers living in Kolkata city are not completely immunized by 12 months of age. This qualitative study aims to explore the barriers to immunization of these children as perceived by their caregivers and the local health care service providers. In-depth interviews were conducted after obtaining written informed consent. Audio recording and hand-recorded notes were used with permission. The transcripts were coded and analyzed using grounded theory. Deteriorating socioeconomic status, tightening of time schedule of caregivers due to illness in the family, stigma, discrimination, and lack of awareness about immunization prove to be major barriers for immunization of the HIV-exposed children. Interplay of these factors coupled with harassment and negative attitudes of service providers toward HIV-affected/HIV-infected people also impede immunization. The intervention efforts need to address these social barriers and adverse life events to improve immunization coverage. PMID:23666833

    HIV-infected children usually live in vulnerable situations, experiencing discrimination and stigma commonly felt by other people living with HIV/AIDS. The present study aims to analyse primary socialisation of HIV-infected children and adolescents recruited from a public health service in Rio de Janeiro (Brazil) as a social process that shapes a new generation of stigmatised and vulnerable persons. Research was informed by an interactionist perspective, focusing on key aspects of HIV-infected children and adolescents life histories under the conceptual frame of Erving Goffman's theories regarding "moral careers". Goffman defines the making of a moral career as the process through which a person learns that she/he possesses a particular attribute, which may lead her/him to be discredited by members of the surrounding society. We have identified aspects of life histories of HIV-vertically infected children and adolescents for each aspect of "moral career" as described by Goffman, relating them to as family structure, the experience of living HIV within the family, and the position and family role of a given subject. The patterns of "moral career" proposed by Goffman in 1963 were useful in identifying components of HIV-related stigma among children and adolescents. These include gender and social disadvantages, difficulty in coping with a child with a potentially severe disease, orphanhood, abandonment, adoption and disclosure of one's HIV serostatus. Primary socialisation of HIV-infected children and adolescents is a key piece of the complex HIV/AIDS-labelling process that could be targeted by interventions aiming to decrease stigma and marginalisation. Health care workers and stakeholders should be committed to ensuring education and guaranteeing the legal rights of this specific population, including the continuous provision of quality health care, full access to school and support to full disclosure of HIV diagnosis.

    Introduction Current knowledge on morbidity and mortality in HIV-infected children comes from data collected in specific research programmes, which may offer a different standard of care compared to routine care. We described hospitalization data within a large observational cohort of HIV-infected children in West Africa (IeDEA West Africa collaboration). Methods We performed a six-month prospective multicentre survey from April to October 2010 in five HIV-specialized paediatric hospital wards in Ouagadougou, Accra, Cotonou, Dakar and Bamako. Baseline and follow-up data during hospitalization were recorded using a standardized clinical form, and extracted from hospitalization files and local databases. Event validation committees reviewed diagnoses within each centre. HIV-related events were defined according to the WHO definitions. Results From April to October 2010, 155 HIV-infected children were hospitalized; median age was 3 years [1–8]. Among them, 90 (58%) were confirmed for HIV infection during their stay; 138 (89%) were already receiving cotrimoxazole prophylaxis and 64 children (40%) had initiated antiretroviral therapy (ART). The median length of stay was 13 days (IQR: 7–23); 25 children (16%) died during hospitalization and four (3%) were transferred out. The leading causes of hospitalization were WHO stage 3 opportunistic infections (37%), non-AIDS-defining events (28%), cachexia and other WHO stage 4 events (25%). Conclusions Overall, most causes of hospitalizations were HIV related but one hospitalization in three was caused by a non-AIDS-defining event, mostly in children on ART. HIV-related fatality is also high despite the scaling-up of access to ART in resource-limited settings. PMID:24763078

    CD4⁺ T-lymphocyte destruction, microbial translocation, and systemic immune activation are the main mechanisms of the pathogenesis of human immunodeficiency virus type 1 (HIV) infection. To investigate the impact of HIV infection and antiretroviral therapy (ART) on the immune profile of and microbial translocation in HIV-infected children, 60 HIV vertically infected children (31 without ART: HIV(+) and 29 with ART: ART(+)) and 20 HIV-uninfected children (HIV(-)) aged 2-12 years were recruited in Vietnam, and their blood samples were immunologically and bacteriologically analyzed. Among the HIV(+) children, the total CD4⁺-cell and their subset (type 1 helper T-cell (Th1)/Th2/Th17) counts were inversely correlated with age (all p < 0.05), whereas regulatory T-cell (Treg) counts and CD4/CD8 ratios had become lower, and the CD38⁺HLA (human leukocyte antigen)-DR⁺CD8⁺- (activated CD8⁺) cell percentage and plasma soluble CD14 (sCD14, a monocyte activation marker) levels had become higher than those of HIV(-) children by the age of 2 years; the CD4/CD8 ratio was inversely correlated with the plasma HIV RNA load and CD8⁺-cell activation status. Among the ART(+) children, the total CD4⁺-cell and Th2/Th17/Treg-subset counts and the CD4/CD8 ratio gradually increased, with estimated ART periods of normalization being 4.8-8.3 years, whereas Th1 counts and the CD8⁺-cell activation status normalized within 1 year of ART initiation. sCD14 levels remained high even after ART initiation. The detection frequency of bacterial 16S/23S ribosomal DNA/RNA in blood did not differ between HIV-infected and -uninfected children. Thus, in children, HIV infection caused a rapid decrease in Treg counts and the early activation of CD8⁺ cells and monocytes, and ART induced rapid Th1 recovery and early CD8⁺-cell activation normalization but had little effect on monocyte activation. The CD4/CD8 ratio could therefore be an additional marker for ART monitoring. PMID:27490536

    CD4+ T-lymphocyte destruction, microbial translocation, and systemic immune activation are the main mechanisms of the pathogenesis of human immunodeficiency virus type 1 (HIV) infection. To investigate the impact of HIV infection and antiretroviral therapy (ART) on the immune profile of and microbial translocation in HIV-infected children, 60 HIV vertically infected children (31 without ART: HIV(+) and 29 with ART: ART(+)) and 20 HIV-uninfected children (HIV(−)) aged 2–12 years were recruited in Vietnam, and their blood samples were immunologically and bacteriologically analyzed. Among the HIV(+) children, the total CD4+-cell and their subset (type 1 helper T-cell (Th1)/Th2/Th17) counts were inversely correlated with age (all p < 0.05), whereas regulatory T-cell (Treg) counts and CD4/CD8 ratios had become lower, and the CD38+HLA (human leukocyte antigen)-DR+CD8+- (activated CD8+) cell percentage and plasma soluble CD14 (sCD14, a monocyte activation marker) levels had become higher than those of HIV(−) children by the age of 2 years; the CD4/CD8 ratio was inversely correlated with the plasma HIV RNA load and CD8+-cell activation status. Among the ART(+) children, the total CD4+-cell and Th2/Th17/Treg-subset counts and the CD4/CD8 ratio gradually increased, with estimated ART periods of normalization being 4.8–8.3 years, whereas Th1 counts and the CD8+-cell activation status normalized within 1 year of ART initiation. sCD14 levels remained high even after ART initiation. The detection frequency of bacterial 16S/23S ribosomal DNA/RNA in blood did not differ between HIV-infected and -uninfected children.

    2004-03-01

    Highly active antiretroviral therapy in HIV-infected children has been associated with a dramatic decrease in progression to AIDS and HIV-related deaths, and infected children currently have an excellent quality of life. Antiretroviral drugs cannot eradicate the virus, although they can achieve a situation of latent infection. However, chronic use of these drugs has multiple adverse effects, the most important of which are metabolic complications. The large number of drugs required and patient characteristics such as age, tolerance to drugs, adherence, and social problems make unifying the criteria for initial therapy in HIV-infected children difficult. A balance should be sought between not delaying the start of treatment, to avoid immunologic deterioration, and minimizing the long-term adverse effects of the therapy. The present treatment recommendations are adapted from international guidelines and are based on a literature review and on our own experience. Our group previously published recommendations on the treatment of HIV-infected children and the aim of the present article is to provide an update. PMID:14987518

    Background. Though micronutrients are vital in the pathogenesis of human immunodeficiency virus infection, most studies have been conducted in adults. Knowledge of the status of key micronutrients in HIV infected African children will indicate if supplementation may be beneficial to these children living in this resource-poor region. Objectives. We sought to determine the micronutrient status and associated factors of HAART-naïve HIV infected children and compare them with those of the HIV negative controls. Methods. We enrolled 70 apparently stable HAART naïve HIV infected children. Seventy age and sex matched HIV negative children were equally enrolled as the controls. Their social class, anthropometry, clinical stage, CD4 counts, serum zinc, selenium, and vitamin C were determined. Results. The prevalence of zinc, selenium, and vitamin C deficiency in HIV infected subjects was 77.1%, 71.4%, and 70.0%, respectively, as compared to 44.3%, 18.6%, and 15.7% in HIV negative controls. Among the HIV infected subjects, 58.6% were deficient in the three micronutrients. Micronutrient status was related to the weight, clinical, and immunological stages but not BMI or social class. Conclusion. Deficiency of these key micronutrients is widely prevalent in HAART naïve HIV infected children irrespective of social class. This suggests that supplementation trial studies may be indicated in this population. PMID:25180086

    Mitochondrial abnormalities may lead to metabolic complications in HIV-infected children who have been receiving long-term antiretroviral treatment. We conducted a matched, case-control study comparing 21 HIV-infected children with insulin resistance (cases) to 21 HIV-infected children without insulin resistance (controls) to assess differences in mitochondrial DNA (mtDNA) copies/cell and oxidative phosphorylation NADH dehydrogenase (C1) and cytochrome c oxidase (C4) enzyme activities in peripheral blood mononuclear cells. MtDNA copies/cell tended to be lower in cases, and fasting serum glucose levels were inversely and significantly correlated with C1 enzyme activity, more so in cases. Larger pediatric studies should evaluate mitochondrial etiologies of insulin resistance and determine the role of antiretroviral therapies or HIV infection on mitochondrial dysfunction.

    Presentation of pulmonary tuberculosis (PTB) as acute pneumonia in severely-malnourished and HIV-positive children has received very little attention, although this is very important in the management of pneumonia in children living in communities where TB is highly endemic. Our aim was to identify confirmed TB in children with acute pneumonia and HIV infection and/or severe acute malnutrition (SAM) (weight-for-length/height or weight-for-age z score <-3 of the WHO median, or presence of nutritional oedema). We conducted a literature search, using PubMed and Web of Science in April 2013 for the period from January 1974 through April 2013. We included only those studies that reported confirmed TB identified by acid fast bacilli (AFB) through smear microscopy, or by culture-positive specimens from children with acute pneumonia and SAM and/or HIV infection. The specimens were collected either from induced sputum (IS), or gastric lavage (GL), or broncho-alveolar lavage (BAL), or percutaneous lung aspirates (LA). Pneumonia was defined as the radiological evidence of lobar or patchy consolidation and/or clinical evidence of severe/ very severe pneumonia according to the WHO criteria of acute respiratory infection. A total of 17 studies met our search criteria but 6 were relevant for our review. Eleven studies were excluded as those did not assess the HIV status of the children or specify the nutritional status of the children with acute pneumonia and TB. We identified only 747 under-five children from the six relevant studies that determined a tubercular aetiology of acute pneumonia in children with SAM and/or positive HIV status. Three studies were reported from South Africa and one each from the Gambia, Ethiopia, and Thailand where 610, 90, 35, and 12 children were enrolled and 64 (10%), 23 (26%), 5 (14%), and 1 (8%) children were identified with active TB respectively, with a total of 93 (12%) children with active TB.

    CD8 T cells are divided into naive and memory subsets according to both function and phenotype. In HIV-negative children, the naive subset is present at high frequencies, whereas memory cells are virtually absent. Previous studies have shown that the overall number of CD8 T cells does not decrease in HIV-infected children. In studies here, we use multiparameter flow cytometry to distinguish naive from memory CD8 T cells based on expression of CD11a, CD45RA, and CD62L. With this methodology, we show that within the CD8 T cell population, the naive subset decreases markedly (HIV+ vs. HIV-, 190 vs. 370 cells/microliter; P < or = 0.003), and that there is a reciprocal increase in memory cells, such that the total CD8 T cell counts remained unchanged (800 vs. 860 cells/microliter; P < or = 0.76). In addition, we show that for HIV-infected children, the naive CD8 T cell and total CD4 T cell counts correlate (chi 2 P < or = 0.001). This correlated loss suggests that the loss of naive CD8 T cells in HIV infection may contribute to the defects in cell-mediated immunity which become progressively worse as the HIV disease progresses and CD4 counts decrease.

    The influence of bacterial lysate [see text]PC-19 on the mucosal immunity of children with HIV infection was evaluated. The action of this topical immunomodulator was found to increase the synthesis of sIgA, which was indirectly reflected in a rise of the local immunity of the upper respiratory ways, preventing the aggravation of the chronic focal infection and the main disease. It should be pointed out that in a group of HIV-infected children and adolescents with an initially high level of salivary IgG the prescription of preparation [see text]PC-19 led to its considerable decrease. A decrease in the level of IgG and a rise in the content of sIgA in saliva under the action of the preparation correlated with a decrease in inflammatory changes in the nasopharyngeal mucosa. On the basis of results obtained in this study additions to the algorithm of the prophylactic medical observation of children and adolescents with HIV infection have been developed. PMID:16758905

    Background Intestinal parasitoses are common amongst people living in developing countries. They may impact negatively on the growth and health of immune competent children. There is paucity of information on the association between HIV and intestinal parasitoses in African children. Objective To identify the intestinal infections responsible for infections in HIV infected children and document characteristics of HIV infected children at a Nigerian teaching hospital. Materials and Methods Consecutive children attending a Paediatric anti-retroviral clinic were studied. Information such as socio-demographics and clinical characteristics elicited from clinical examination were recorded in the proforma. Stool samples of the children were obtained and examined for intestinal parasites. Data was analysed with the SPSS 18 software. Results A total 52 children were studied and their age ranged between 6 months and 14 years, with a mean of 6.5 years ± 3.93. The 52 were made up of 27 boys and 25 girls, giving a male: female ratio of 1.1:1. 10 (19.2%) of the 52 children were infected with cryptosporidium spp, while 1(1.9%) had Ascaris lumbricoides infestation. Anti-helminthics had previously been administered to 86.5% of children studied. Those who previously received anti-helminthics had lower prevalence estimates of cryptosporidium infections. (p<0.01, RR = 0.42, 95%CI = 0.20 – 0.90). Children on co-trimoxazole prophylaxis had lower prevalence estimates of cryptosporidium infections. (P<0.01, RR = 0.35, 95%CI = 0.14 – 0.91). Use of highly active antiretroviral drugs was also associated with lower prevalence estimates of intestinal cryptosporidium. (p=0.04, RR = 0.58, 95%CI = 0.31 – 1.10). Eight of the 10 children infected with cryptosporidium had recurrent abdominal pain in comparison with the six with recurrent abdominal pain amongst the 42 without cryptosporidial infections. (p<0.01, RR=5.6, 95%CI= 2.51 – 12.1). Conclusion Cryptosporidial infection is the most

    Short summary The EPIICAL (Early-treated Perinatally HIV-infected Individuals: Improving Children’s Actual Life with Novel Immunotherapeutic Strategies) project arises from the firm belief that perinatally infected children treated with suppressive antiretroviral therapy (ART) from early infancy represent the optimal population model in which to study novel immunotherapeutic strategies aimed at achieving ART-free remission. This is because HIV-infected infants treated within 2–3 months of life have a much reduced viral reservoir size, and rarely show HIV-specific immunity but preserve normal immune development. The goal of EPIICAL is the establishment of an international collaboration to develop a predictive platform using this model to select promising HIV therapeutic vaccine candidates, leading to prioritisation or deprioritisation of novel immunotherapeutic strategies. To establish this platform, the EPIICAL Consortium aims to: develop predictive models of virological and immunological dynamics associated with response to early ART and to treatment interruption using available data from existing cohorts/studies of early-treated perinatally HIV-infected children; optimise methodologies to better characterise immunological, virological and genomic correlates/profiles associated with viral control; test novel immunotherapeutic strategies using in vivo proof-of-concept (PoC) studies with the aim of inducing virological, immunological and transcriptomic correlates/profiles equivalent to those defined by the predictive model. This approach will strengthen the capacity for discovery, development and initial testing of new therapeutic vaccine strategies through the integrated efforts of leading international scientific groups, with the aim of improving the health of HIV-infected individuals.

    Background: Human milk oligosaccharides (HMOs) have multiple immunomodulatory functions that influence child health. Objective: In this study we investigated whether HMO composition influences survival to 2 y of age in HIV-infected and HIV-exposed, uninfected (HEU) children during and after breastfeeding. Methods: In the context of an early weaning trial in 958 HIV-infected women in Lusaka, Zambia, we conducted a nested case-cohort analysis of mortality to 2 y of age among 103 HIV-infected and 143 HEU children. Breast-milk samples collected at 1 mo postpartum were analyzed for HMO content. Samples were selected to include mothers of all HIV-infected children detected by 6 wk of age, of whom 63 died at <2 y of age; mothers of all HEU children who died at <2 y of age (n = 66); and a random sample of 77 HEU survivors. Associations before and after weaning in HIV-infected and HEU infants separately were investigated by using Cox models. Results: Among HEU children, higher maternal breast-milk concentrations of 2-linked fucosylated HMOs [2′-fucosyllactose and lacto-N-fucopentaose (LNFP) I] (HR: 0.33; 95% CI: 0.14, 0.74) as well as non–2-linked fucosylated HMOs (3-fucosyllactose and LNFP II/III; HR: 0.28; 95% CI: 0.13, 0.67) were significantly associated with reduced mortality during, but not after, breastfeeding after adjustment for confounders. Breastfeeding was protective against mortality only in HEU children with high concentrations of fucosylated HMOs. Among HIV-infected children, no consistent associations between HMOs and mortality were observed, but breastfeeding was protective against mortality. Conclusions: The oligosaccharide composition of breast milk may explain some of the benefits of breastfeeding in HEU children. HIV infection may modulate some of the consequences of HMOs on child survival. PMID:25527660

    Mental health problems (MHPs) among children with perinatal HIV infection have been described prior to and during the highly active antiretroviral therapy (HAART) era. Yet child, caregiver and socio-demographic factors associated with MHPs are not fully understood. We examined the prevalence of MHPs among older children and adolescents with perinatal HIV exposure, including both perinatally HIV-infected (PHIV+) and perinatally HIV-exposed but uninfected (PHEU) youth. Our aims were to identify the impact of HIV infection by comparing PHIV+ and PHEU youth and to delineate risk factors associated with MHPs, in order to inform development of appropriate prevention and intervention strategies. Youth and their caregivers were interviewed with the Behavior Assessment System for Children, 2nd edition (BASC-2) to estimate rates of at-risk and clinically significant MHPs, including caregiver-reported behavioral problems and youth-reported emotional problems. The prevalence of MHPs at the time of study entry was calculated for the group overall, as well as by HIV status and by demographic, child health, and caregiver characteristics. Logistic regression models were used to identify factors associated with youth MHPs. Among 416 youth enrolled between March 2007 and July 2009 (295 PHIV+, 121 PHEU), the overall prevalence of MHPs at entry was 29% and greater than expected based on recent national surveys of the general population. MHPs were more likely among PHEU than among PHIV+ children (38% versus 25%, p < 0.01). Factors associated with higher odds of MHPs at p < 0.10 included caregiver characteristics (psychiatric disorder, limit-setting problems, health-related functional limitations) and child characteristics (younger age and lower IQ). These findings suggest that PHEU children are at high risk for MHPs, yet current models of care for these youth may not support early diagnosis and treatment.

    Regulatory T cells (Tregs) are functionally suppressive CD4 T cells, critical for establishing peripheral tolerance and controlling inflammatory responses. Previous reports of Tregs during chronic HIV disease have conflicting results with higher or lower levels compared with controls. Identifying true Tregs with suppressive activity proves challenging during HIV infection, as traditional Treg markers, CD25 and FOXP3, may transiently upregulate expression as a result of immune activation (IA). Helios is an Ikaros family transcription factor that marks natural Tregs with suppressive activity and does not upregulate expression after activation. Coexpression of FOXP3 and Helios has been suggested as a highly specific marker of "bona fide" Tregs. We evaluated Treg subsets by FOXP3 coexpressed with either CD25 or Helios and their association with HIV disease progression in perinatally infected HIV-positive children. Identifying Tregs by FOXP3 coexpression with Helios rather than CD25 revealed markedly higher Treg frequencies, particularly in HIV+ children. Regardless of antiretroviral therapy, HIV-infected children had a selective expansion of memory FOXP3+Helios+ Tregs. The rise in memory Tregs correlated with declining HIV clinical status, indicated by falling CD4 percentages and CD4:CD8 ratios and increasing HIV plasma viremia and IA. In addition, untreated HIV+ children exhibited an imbalance between the levels of Tregs and activated T cells. Finally, memory Tregs expressed IA markers CD38 and Ki67 and exhaustion marker, PD-1, that tightly correlated with a similar phenotype in memory CD4 T cells. Overall, HIV-infected children had significant disruptions of memory Tregs that associated with advancing HIV disease. PMID:27003495

    Objectives To measure the prevalence and to identify risk factors of hearing impairment in human immunodeficiency virus-infected children living in Peru. Study design Cross-sectional observational study. Setting Two public hospitals and 1 nonprofit center in Lima, Peru, between August 2009 and April 2010. Subjects A total of 139 HIV-infected children, ages 4 to 19 years. Methods Hearing impairment and otologic health were assessed with pure tone audiometry, tympanometry, and otoscopy. The primary outcome was hearing loss, defined as average threshold >25dB for 0.5, 1, 2, and 4 kHz, in one or both ears. Historical and socioeconomic information was obtained through parental survey and medical chart review. Statistical analysis included univariate analysis and multivariate logistic regression. Results Fifty-four (38.8%) of 139 children had hearing impairment. On multivariate analysis, risk factors included: tympanic membrane perforation (odds ratio [OR] 7.08; 95% confidence interval [CI], 1.65-30.5; P = .01), abnormal tympanometry (OR 2.71; 95% CI, 1.09-6.75; P = .03), cerebral infection (OR 11.6; 95% CI, 1.06-126; P = .05), seizures (OR 5.20; 95% CI, 1.21-22.4; P = .03), and CD4 cell count <500 cells/mm3 (OR 3.53; 95% CI, 1.18-10.5; P = .02). Conclusions The prevalence of hearing impairment in HIV-infected children in Lima, Peru was 38.8%. Middle ear disease, prior cerebral infection, and low CD4 cell count were significantly associated with hearing impairment. The high prevalence of hearing impairment emphasizes the need for periodic hearing assessment in the routine clinical care of HIV-infected children. PMID:22128111

    This qualitative study aims to investigate parental HIV disclosure and psychological impact from the perspectives of their children. In-depth individual interviews with 47 children who had lost one or both parents to AIDS were conducted in China. All transcripts were coded using the software ATLAS.ti 5. Results showed that few of children knew of parental HIV status before the death of their parents. The main disclosers were the children’s current caregivers. Some children knew about their parent’s HIV infection based on their own observations or through overheard conversation, or their interactions with villagers. Both positive and negative psychological outcomes related to parental HIV disclosure were reported. Psychological counseling is needed for both parents and children to dealing with the parental HIV infection. PMID:24761258

    Maintaining linear growth and weight gain in HIV-infected children is often difficult. Nutritional evaluation and support are recognised as important factors to improve their quality of life. Combination antiretroviral therapy including protease inhibitors (HAART) reduces HIV-viral load and improves survival, quality of life and nutritional status. Our study aimed to determine changes in nutrional status based on body weight, height and nutritional habits, of HIV-infected children receiving HAART. Possible side effects of lipid metabolism were also studied. Twenty five children, 13 treated with HAART (group B) were followed up for 12 months. We did not observe statistically significant differences in nutritional status over that time or between groups A and B. Inadequate energy intake was more common in patients with advanced HIV-disease. Hyperlipidemia was found in 70% of children receiving ritonavir and in approximately 50% of children receiving nelfinavir. We observed an important although not statistically significative modification in the height of those in group B. PMID:11091066

    By April 1995, 302 cases of vertically acquired HIV infection had been reported through the British Paediatric Association Surveillance Unit. Over 50% of these children had developed an AIDS indicator disease, including nine malignancies (seven cases of non-Hodgkin's lymphoma (NHL) and two of Kaposi's sarcoma). There were two other malignancies that were not AIDS indicator diseases. In children less than 5 years of age the incidence of NHL was approximately 2500 times greater than expected in the UK child population. Three children presented with NHL as their AIDS indicator disease and four developed NHL at a median of 14 (range 10-19) months after the initial diagnosis of AIDS. Six of the seven children died at a median of 6.5 (range 2-14) months after the diagnosis of NHL. The seventh child responded to treatment and is alive nearly four years later. Histology was available in five cases, of which four were of B cell and one of T cell origin. Epstein-Barr virus was detected in all three patients with NHL where it was sought; all had B cell lymphomas. Although comparatively rare, malignancies occur in children infected with HIV and may be the presenting illness. Paediatricians now need to consider HIV infection as a predisposing cause of childhood cancer, especially NHL. PMID:9166025

    Introduction In 2014 the Joint United Nations Programme on HIV/AIDS defined the ambitious 90–90–90 targets for 2020, in which 90% of people living with HIV must be diagnosed, 90% of those diagnosed should be on sustained therapy and 90% of those on therapy should have an undetectable viral load. Children are considered to be a key focus population for these targets. This review will highlight key components of the epidemiology, prevention and treatment of tuberculosis (TB) in HIV-infected children in the era of increasing access to antiretroviral therapy (ART) and their relation to the 90–90–90 targets. Discussion The majority of HIV-infected children live in countries with a high burden of TB. In settings with a high burden of both diseases such as in sub-Saharan Africa, up to 57% of children diagnosed with and treated for TB are HIV-infected. TB results in substantial morbidity and mortality in HIV-infected children, so preventing TB and optimizing its treatment in HIV-infected children will be important to ensuring good long-term outcomes. Prevention of TB can be achieved by increasing access to ART to both children and adults, and appropriate provision of isoniazid preventative therapy. Co-treatment of HIV and TB is complicated by drug-drug interactions particularly due to the use of rifampicin; these may compromise virologic outcomes if appropriate corrective actions are not taken. There remain substantial operational challenges, and improved integration of paediatric TB and HIV services, including with antenatal and routine under-five care, is an important priority. Conclusions TB may be an important barrier to achievement of the 90–90–90 targets, but specific attention to TB care in HIV-infected children may provide important opportunities to enhance the care of both TB and HIV in children.

    Children of HIV-infected women are likely to be profoundly affected by their mothers' infection, regardless of their own infection status and their number will increase with the spread of infection among women in Europe. This article describes the family circumstances and social care of 1,123 children born to HIV-infected women enrolled in the European Collaborative Study and followed prospectively from birth. Most mothers were white, married or cohabiting, asymptomatic and had a history of drug use, with 45% currently using injecting drugs at the time of enrollment. Seventy percent of children were cared for by their mothers and/or fathers consistently in their first four years of life, but by age eight an estimated 60% will have lived away from their parents (i.e. with foster or adoptive parents, other relatives or in an institution). Whether or not a child was infected did not influence the likelihood of living in alternative care. Maternal injecting drug use, single parenthood and health status were the major reasons necessitating alternative care. The type of alternative care varied according to maternal characteristics, child's age and geographic location. The mothers of 98 children had died and average age at maternal death was four years.

    Objective HIV-infection is an established risk for diarrheal severity, less is known about specific enteric pathogens associated with HIV status. We determined associations of selected enteric pathogens with HIV-infection and HIV-exposure among Kenyan children. Design Cross-sectional study among 6 months to 15 year olds presenting to two Western Kenya District hospitals with acute diarrhea between 2011–2013. Methods Stool was tested using standard bacterial culture and microscopy for ova and parasites. HIV testing was obtained on children and mothers. Enteric pathogen prevalence was compared between HIV-infected and HIV-uninfected children and between HIV-exposed uninfected (HEU) and HIV-unexposed. Unadjusted and adjusted prevalence ratios (PR) for selected pathogens by HIV-status were estimated using relative risk (RR) regression and P-values. Age, site, income, household crowding, water source/treatment, anthropometrics, cotrimoxazole use, and breastfeeding history were accounted for in multivariable models. Results Among 1,076 children, median age was 22 months (interquartile range: 11–42), 56 (5.2%) were HIV-infected, and 10.3%(105/1020) of HIV-uninfected children were HIV-exposed. The following organisms were most frequently isolated from stool: enteroaggregative Escherichia coli (13.3%), Giardia spp. (11.1%) Campylobacter (6.3%), enteropathogenic Escherichia coli (EPEC) (6.1%) and Cryptosporidium spp. (3.7%). Accounting for age, HIV-infection was associated with EPEC infection (PR: 3.70, P=0.002) while HIV-exposure was associated with Cryptosporidium among HIV-uninfected children (PR: 2.81, P=0.005). Conclusion EPEC and Cryptosporidium infections were more common in HIV-infected and HIV-exposed children, respectively. This could explain the increased mortality attributed to these pathogens in other studies. Interventions targeting EPEC and Cryptosporidium may reduce morbidity and mortality in high HIV-prevalence settings. PMID:25028987

    Cytomegalovirus (CMV) is a prevalent pathogen in the immunocompromised host and invasive pneumonia is a feared complication of the virus in this population. In this pediatric case series we characterized CMV lung infection in 15 non-HIV infected children (median age 3 years; IQR 0.2–4.9 years), using current molecular and imaging diagnostic modalities, in combination with respiratory signs and symptoms. The most prominent clinical and laboratory findings included cough (100%), hypoxemia (100%), diffuse adventitious breath sounds (100%) and increased respiratory effort (93%). All patients had abnormal lung images characterized by ground glass opacity/consolidation in 80% of cases. CMV was detected in the lung either by CMV PCR in bronchoalveolar lavage (82% detection rate) or histology/immunohistochemistry in lung biopsy (100% detection rate). CMV caused respiratory failure in 47% of children infected and the overall mortality rate was 13.3%. Conclusion: CMV pneumonia is a potential lethal disease in non-HIV infected children that requires a high-index of suspicion. Common clinical and radiological patterns such as hypoxemia, diffuse adventitious lung sounds and ground-glass pulmonary opacities may allow early identification of CMV lung infection in the pediatric population, which may lead to prompt initiation of antiviral therapy and better clinical outcomes.

    The effect of perinatal HIV infection and exposure on sub-clinical auditory function can be measured with distortion product otoacoustic emissions (DPOAEs). DPOAEs were obtained at 4 frequency bins (1, 2, 3 and 4 kHz) and categorized by a signal-to-noise ratio. HIV infection was not associated with poorer DPOAEs. Among HIV-infected children, HIV viral load≥400 copies/mL had significantly lower odds of better DPOAEs. PMID:25742077

    Presentation of pulmonary tuberculosis (PTB) as acute pneumonia in severely-malnourished and HIV-positive children has received very little attention, although this is very important in the management of pneumonia in children living in communities where TB is highly endemic. Our aim was to identify confirmed TB in children with acute pneumonia and HIV infection and/or severe acute malnutrition (SAM) (weight-for-length/height or weight-for-age z score <-3 of the WHO median, or presence of nutritional oedema). We conducted a literature search, using PubMed and Web of Science in April 2013 for the period from January 1974 through April 2013. We included only those studies that reported confirmed TB identified by acid fast bacilli (AFB) through smear microscopy, or by culture-positive specimens from children with acute pneumonia and SAM and/or HIV infection. The specimens were collected either from induced sputum (IS), or gastric lavage (GL), or broncho-alveolar lavage (BAL), or percutaneous lung aspirates (LA). Pneumonia was defined as the radiological evidence of lobar or patchy consolidation and/or clinical evidence of severe/very severe pneumonia according to the WHO criteria of acute respiratory infection. A total of 17 studies met our search criteria but 6 were relevant for our review. Eleven studies were excluded as those did not assess the HIV status of the children or specify the nutritional status of the children with acute pneumonia and TB. We identified only 747 under-five children from the six relevant studies that determined a tubercular aetiology of acute pneumonia in children with SAM and/or positive HIV status. Three studies were reported from South Africa and one each from the Gambia, Ethiopia, and Thailand where 610, 90, 35, and 12 children were enrolled and 64 (10%), 23 (26%), 5 (14%), and 1 (8%) children were identified with active TB respectively, with a total of 93 (12%) children with active TB.

    OBJECTIVES: This study sought to determine the number, characteristics, and living situations of children of HIV-infected adults. METHODS: Interviews were conducted in 1996 and early 1997 with a nationally representative probability sample of 2864 adults receiving health care for HIV within the contiguous United States. RESULTS: Twenty-eight percent of infected adults in care had children. Women were more likely than men to have children (60% vs 18%) and to live with them (76% vs 34%). Twenty-one percent of parents had been hospitalized during the previous 6 months, and 10% had probably been drug dependent in the previous year. Parents continued to have children after being diagnosed with HIV: 12% of all women conceived and bore their youngest child after diagnosis, and another 10% conceived before but gave birth after diagnosis. CONCLUSIONS: Clinical and support services for people affected by the HIV epidemic should have a family focus. PMID:10897185

    Summary A provider-assisted, counseling-based, pediatric HIV disclosure model was developed and implemented at two tertiary-care hospitals in Bangkok, Thailand. All undisclosed perinatally acquired HIV-infected children, ages 7–18 years, and their caretakers were offered the four-step disclosure service, including: screening, readiness assessments and preparation, disclosure sessions, and follow-up evaluations. To assess psychosocial outcomes of disclosure, we compared the scores of the Children Depression Inventory and the PedsQL 4.0™ at baseline and at 2-month and 6-month follow-up visits, and compared the scores of the Child Behavioral Checklist at baseline and at 6-month follow-up. Disclosure was made to 186 children, 160 of whom completed post-disclosure assessments. The median Children’s Depression Inventory score in 135 children decreased significantly from 11 at baseline to 8 at 2-month and 6-month follow-up (p < 0.01). The median PedsQL 4.0™ scores in 126 children increased significantly from 78 at baseline to 80 at 2-month and 84 at 6-month follow-up (p = 0.04). The median Child Behavioral Checklist scores were not significantly changed. In conclusion, pediatric HIV diagnosis disclosure using this model was found to have positive effect on the children’s mood and quality of life, and no negative effect on children’s behaviours. This disclosure program should be expanded to improve psychosocial health of HIV-infected children. PMID:25829519

    Background Assumptions about survival of HIV-infected children in Africa without antiretroviral therapy need to be updated to inform ongoing UNAIDS modelling of paediatric HIV epidemics among children. Improved estimates of infant survival by timing of HIV-infection (perinatally or postnatally) are thus needed. Methodology/Principal Findings A pooled analysis was conducted of individual data of all available intervention cohorts and randomized trials on prevention of HIV mother-to-child transmission in Africa. Studies were right-censored at the time of infant antiretroviral initiation. Overall mortality rate per 1000 child-years of follow-up was calculated by selected maternal and infant characteristics. The Kaplan-Meier method was used to estimate survival curves by child's HIV infection status and timing of HIV infection. Individual data from 12 studies were pooled, with 12,112 children of HIV-infected women. Mortality rates per 1,000 child-years follow-up were 39.3 and 381.6 for HIV-uninfected and infected children respectively. One year after acquisition of HIV infection, an estimated 26% postnatally and 52% perinatally infected children would have died; and 4% uninfected children by age 1 year. Mortality was independently associated with maternal death (adjusted hazard ratio 2.2, 95%CI 1.6–3.0), maternal CD4<350 cells/ml (1.4, 1.1–1.7), postnatal (3.1, 2.1–4.1) or peri-partum HIV-infection (12.4, 10.1–15.3). Conclusions/Results These results update previous work and inform future UNAIDS modelling by providing survival estimates for HIV-infected untreated African children by timing of infection. We highlight the urgent need for the prevention of peri-partum and postnatal transmission and timely assessment of HIV infection in infants to initiate antiretroviral care and support for HIV-infected children.

    Worldwide, the benefits of combined antiretroviral (ARV) therapy in morbidity and mortality due to perinatally acquired human immunodeficiency virus infection are beyond question and outweigh the toxicity these drugs have been associated with in HIV-infected children and adolescents to date. In puberty, abnormal body fat distribution is stigmatizating and leads to low adherence to ARV treatment. The other metabolic comorbidities (mitochondrial toxicity, dyslipidemias, insulin resistance and low bone mineral density) and renal toxicity, albeit nonsymptomatic in most children, are increasingly being reported and potentially put this population at risk for early cardiovascular or cerebrovascular atherosclerotic disease, diabetes, pathologic fractures or premature renal failure in the third and fourth decades of life. Evidence from available studies is limited because of methodological limitations and also because of several HIV-unrelated factors influencing, to some degree, the development of these conditions. Current recommendations for the prevention, diagnosis, monitoring and treatment of metabolic and renal adverse effects in HIV-children and adolescents are based on adult studies, observational pediatric studies and experts' consensus. Healthy lifestyle habits (regarding diet, exercise and refraining from toxic substances) and wise use of ARV options are the only preventive tools for the majority of patients. Should abnormal findings arise, switches in one or more ARV drugs have proved useful. Specific therapies are also available for some of these comorbidities, although the experience in the pediatric age is still very scarce. We aim to summarize the epidemiological, clinical and therapeutic aspects of metabolic and renal adverse effects in vertically HIV-infected children and adolescents. PMID:25629891

    Background Retaining patients with HIV infection in care is still a major challenge in sub- Saharan Africa, particularly in the Democratic Republic of Congo (DRC) where the antiretroviral treatment (ART) coverage is low. Monitoring retention is an important tool for evaluating the quality of care. Methods and Findings A review of medical records of HIV -infected children was performed in three health facilities in the DRC: the Amo-Congo Health center, the Monkole Clinic in Kinshasa, and the HEAL Africa Clinic in Goma. Medical records of 720 children were included. Kaplan Meier curves were constructed with the probability of retention at 6 months, 1 year, 2 years and 3 years. Retention rates were: 88.2% (95% CI: 85.1%–90.8%) at 6 months; 85% (95% CI: 81.5%–87.6%) at one year; 79.4% (95%CI: 75.5%–82.8%) at two years and 74.7% (95% CI: 70.5%–78.5%) at 3 years. The retention varied across study sites: 88.2%, 66.6% and 92.5% at 6 months; 84%, 59% and 90% at 12 months and 75.7%, 56.3% and 85.8% at 24 months respectively for Amo-Congo/Kasavubu, Monkole facility and HEAL Africa. After multivariable Cox regression four variables remained independently associated with attrition: study site, CD4 cell count <350 cells/µL, children younger than 2 years and children whose caregivers were member of an independent church. Conclusions Attrition remains a challenge for pediatric HIV positive patients in ART programs in DRC. In addition, the low coverage of pediatric treatment exacerbates the situation of pediatric HIV/AIDS. PMID:25541707

    Context Antiretroviral therapy has been associated with hypercholesterolemia in HIV-infected children. Few longitudinal studies have been conducted to examine this association, however. Objective To evaluate the incidence of and risk factors for development of hypercholesterolemia in a large pediatric study. Design Prospective cohort study (Pediatric AIDS Clinical Trials Group 219C). Participants A total of 2122 perinatally HIV-infected children free of hypercholesterolemia at entry. Outcome Development of hypercholesterolemia (total cholesterol ≥220 mg/dL at 2 consecutive visits). Cox proportional hazards models were used to evaluate risk factors. Results Thirteen percent of children had hypercholesterolemia at entry, and an additional 13% developed hypercholesterolemia during follow-up for an incidence rate of 3.4 cases per 100 person-years (95% confidence interval [CI]: 3.0 to 3.9). After adjustment for age, boosted protease inhibitor (PI) use (hazard ratio [HR] = 13.9, 95% CI: 6.73 to 28.6), nonboosted PI use (HR = 8.65, 95% CI: 4.19 to 17.9), and nonnucleoside reverse transcriptase inhibitor use (HR = 1.33, 95% CI: 1.04 to 1.71) were associated with increased risk of hypercholesterolemia, and higher viral load was protective (>50,000 vs. ≤400 copies/mL; HR = 0.59, 95% CI: 0.39 to 0.90). Self-reported adherent subjects had higher risk. Conclusions PIs were significant risk factors for hypercholesterolemia. Higher viral load was protective and may reflect non-adherence. Further follow-up is critical to evaluate long-term consequences of chronic PI exposure and hypercholesterolemia. PMID:18209684

    HIV/AIDS is an infection characterized by immune cell dysfunction and subsequent immunodeficiency, as well as intestinal disorder. Probiotics are live microbial feed supplements that beneficially affect the host animal by improving intestinal microbial balance and promoting health benefits. The goals of this study were to determine whether the use of probiotics could improve the immune response determined by CD4 cells mm(-3) counts and reduce liquid stool episodes. A randomized double-blind controlled trial with 77 HIV-infected children (2-12 years), divided into two groups: one receiving probiotics (formula containing Bifidobacterium bifidum with Streptococcus thermophilus -2.5 x 10(10) colony forming units) and the other, a standard formula (control group), for 2 months. The CD4 counts (cells mm(-3)) were collected at the beginning and end of the study. The quality and number of stools were assessed by a questionnaire (watery to normal stool consistency). There was an increase in the mean CD4 count in the probiotics group (791 cells mm(-3)) and a small decrease in the control group (538 cells mm(-3)). The change from baseline in mean CD4 cell count was +118 cells mm(-3) vs. -42 cells mm(-3) for children receiving the probiotic formula and control formula, respectively (p = 0.049). A similar reduction in liquid stool consistency in both the groups (p < 0.06), with a slight enhancement in the probiotics group, was observed, but without significant difference (p < 0.522). The incidence of loose-soft stools showed a small decrease in both groups (p < 0.955) and there was an increase in the incidence of normal stool consistency in both the groups (p < 0.01). Our study showed that probiotics have immunostimulatory properties and might be helpful in the treatment of HIV-infected children. PMID:17878180

    Globally, an estimated 3.4 million children are living with HIV, yet little is known about the effects of HIV and antiretroviral treatment (ART) on the developing brain, and the neurodevelopmental and behavioural outcomes of perinatally HIV-infected (PHIV+) adolescents. We reviewed the literature on neurodevelopmental outcomes in PHIV+ children and adolescents, and summarized the current evidence on behaviour, general cognition, specific domains, hearing and language, school performance and physical disabilities due to neurological problems. Evidence suggests that PHIV+ children do not perform as well as controls on general cognitive tests, processing speed and visual-spatial tasks, and are at much higher risk for psychiatric and mental health problems. Children with AIDS-defining diagnoses are particularly at risk for poorer outcomes. A striking finding is the lack of published data specific to the adolescent age group (10-25 years), particularly from resource-constrained countries, which have the highest HIV prevalence. In addition, extreme heterogeneity in terms of timing and source of infection, and antiretroviral experience limits our ability to summarize findings of studies and generalize results to other settings. Due to the complex nature of the developing adolescent brain, environmental influences and variation in access to ART, there is an urgent need for research on the longitudinal trajectory of neurodevelopment among children and adolescents perinatally infected with HIV, especially in high burden resource-constrained settings.

    More than 2 million children globally are living with HIV infection and >90% of these reside in sub-Saharan Africa. Severe acute malnutrition (SAM) remains a major problem for HIV-infected children who live in resource-limited settings (RLS), and SAM is an important risk factor for mortality. SAM in HIV-infected children is associated with complications including electrolyte disorders, micronutrient deficiencies, and severe infections, which contribute to the high mortality. Access to antiretroviral therapy (ART) has significantly improved the survival of HIV-infected children, although the response to ART of children with SAM remains undocumented in the literature. Immune and virologic responses to ART in RLS are similar to those of infected children in resource-rich settings, but delays in initiation of therapy have led to a high early mortality. Antiretroviral drug toxicities have been described in children who receive therapy and may affect their quality of life and long-term survival. Metabolic complications of ART include lipodystrophy, dyslipidemia, lactic acidosis, insulin resistance, and osteopenia. These complications have been well described in adults and children from developed countries, but data from RLS are limited, and these complications may be compounded by SAM. In this article we review the epidemiology, clinical presentation, and complications of SAM in HIV-infected children and the metabolic complications of HIV-infected children in the era of ART, and discuss future research priorities for RLS.

    Background Diagnosing tuberculosis in children is challenging because specimens are difficult to obtain and contain low tuberculosis concentrations, especially with HIV-coinfection. Few studies included well-controls so test specificities are poorly defined. We studied tuberculosis diagnosis in 525 children with and without HIV-infection. Methods and Findings ‘Cases’ were children with suspected pulmonary tuberculosis (n = 209 HIV-negative; n = 81 HIV-positive) and asymptomatic ‘well-control’ children (n = 200 HIV-negative; n = 35 HIV-positive). Specimens (n = 2422) were gastric aspirates, nasopharyngeal aspirates and stools analyzed by a total of 9688 tests. All specimens were tested with an in-house hemi-nested IS6110 PCR that took <24 hours. False-positive PCR in well-controls were more frequent in HIV-infection (P≤0.01): 17% (6/35) HIV-positive well-controls versus 5.5% (11/200) HIV-negative well-controls; caused by 6.7% (7/104) versus 1.8% (11/599) of their specimens, respectively. 6.7% (116/1719) specimens from 25% (72/290) cases were PCR-positive, similar (P>0.2) for HIV-positive versus HIV-negative cases. All specimens were also tested with auramine acid-fast microscopy, microscopic-observation drug-susceptibility (MODS) liquid culture, and Lowenstein-Jensen solid culture that took ≤6 weeks and had 100% specificity (all 2112 tests on 704 specimens from 235 well-controls were negative). Microscopy-positivity was rare (0.21%, 5/2422 specimens) and all microscopy-positive specimens were culture-positive. Culture-positivity was less frequent (P≤0.01) in HIV-infection: 1.2% (1/81) HIV-positive cases versus 11% (22/209) HIV-negative cases; caused by 0.42% (2/481) versus 4.7% (58/1235) of their specimens, respectively. Conclusions In HIV-positive children with suspected tuberculosis, diagnostic yield was so low that 1458 microscopy and culture tests were done per case confirmed and even in children with culture-proven tuberculosis most tests and

    There have been no paediatric randomised trials describing the effect of planned treatment interruptions (PTIs) of antiretroviral therapy (ART) on adherence, or evaluating acceptability of such a strategy. In PENTA 11, HIV-infected children were randomised to CD4-guided PTIs (n = 53) or continuous therapy (CT, n = 56). Carers, and children if appropriate, completed questionnaires on adherence to ART and acceptability of PTIs. There was no difference in reported adherence on ART between CT and PTI groups; non-adherence (reporting missed doses over the last 3 days or marking <100 % adherence since the last clinical visit on a visual analogue scale) was 18 % (20/111) and 14 % (12/83) on carer questionnaires in the CT and PTI groups respectively (odds ratios, OR (95 % CI) = 1.04 (0.20, 5.41), χ(2) (1) = 0.003, p = 0.96). Carers in Europe/USA reported non-adherence more often (31/121, 26 %) than in Thailand (1/73, 1 %; OR (95 % CI) = 54.65 (3.68, 810.55), χ(2) (1) = 8.45, p = 0.004). The majority of families indicated they were happy to have further PTIs (carer: 23/36, 64 %; children: 8/13, 62 %), however many reported more clinic visits during PTI were a problem (carer: 15/36, 42 %; children: 6/12, 50 %).

    After witnessing an episode of poor injection safety in large numbers of children in a rural under-resourced hospital in Uganda, we briefly review our own experience and that of others in investigating HIV infection in children considered unlikely to be through commonly identified routes such as vertical transmission, sexual abuse or blood transfusion. In the majority of cases, parents are HIV uninfected. The cumulative experience suggests that the problem is real, but with relatively low frequency. Vertical transmission is the major route for HIV to children. However, factors such as poor injection safety, undocumented surrogate breast feeding, an HIV-infected adult feeding premasticated food to a weaning toddler, poor hygienic practice in the home and using unsterilised equipment for minor surgical or traditional procedures are of cumulative concern.

    Aims Genetic factors, notably CYP2B6 516G→T [rs3745274] and 983T→C [rs28399499], explain much of the interindividual variability in efavirenz pharmacokinetics, but data from Africa are limited. We characterized relationships between genetic polymorphisms and plasma efavirenz concentrations in HIV-infected Black South African adults and children. Methods Steady-state mid-dosing interval efavirenz concentrations were measured. We genotyped 241 polymorphisms in genes potentially relevant to efavirenz metabolism and transport, including ABCB1, CYP2A6, CYP2B6, CYP3A4, CYP3A5, NR1I2 and NR1I3. Results Among 113 participants (59 adults and 54 children), minor allele frequencies for CYP2B6 516G→T, 983T→C, and 15582C→T [rs4803419] were 0.36, 0.07, and 0.09, respectively. Based on composite CYP2B6 15582/516/983 genotype, there were 33 extensive metabolizer, 62 intermediate metabolizer and 18 slow metabolizer genotypes. Median (IQR) mid-dose efavirenz concentrations were 1.44 (1.21–1.93) µg ml–1, 2.08 (1.68–2.94) µg ml–1 and 7.26 (4.82–8.34) µg ml–1 for extensive, intermediate and slow metabolizers, respectively. In univariate analyses, a model that included composite genotype best predicted efavirenz concentrations (β = 0.28, 95% CI 0.21, 0.35, P = 2.4 × 10–11). Among individual CYP2B6 polymorphisms, 516G→T best predicted efavirenz concentrations (β = 0.22, 95% CI 0.13, 0.30, P = 1.27 × 10−6). There was also associations with 983T→C (β = 0.27, 95% CI 0.10, 0.44, P = 0.002) and 15582C→T (β = 0.11, 95% CI 0.01, 0.22, P = 0.04). Associations were consistent in adults and children. No other polymorphisms were independently associated with efavirenz concentrations. Conclusions Composite CYP2B6 genotype based on CYP2B6 516G→T, 983T→C, and 15582C→T best described efavirenz exposure in HIV-infected Black South African adults and children. PMID:25611810

    Malnutrition and human immunodeficiency virus (HIV)-related complications are commonly seen in HIV-infected children, and these have been shown in high-prevalent areas such as Africa. Antiviral therapy (ART) has notably controlled disease progression, whereas it effectively reverses underweight and growth retardation in HIV-infected children. This study was conducted to evaluate the growth status after initiation of ART in HIV-infected children in China. A retrospective cohort study was conducted based on the National Science and Technology Major Project. HIV-infected children who initiated antiretroviral treatment between January 1st, 2012 and December 31st, 2012 were followed up to December 31st, 2014. Z-scores of height and weight were calculated by WHO Anthro (plus). Linear mixed-effects models were used to model trajectories of weight- and height-for-age Z-scores. Seven hundred forty-four participants enrolled in the study, with 585 participants and 712 participants who had WAZ (weight-for-age Z-score) and HAZ (height-for-age Z-score), respectively, before initiation of ART. Among them, 125 (21.4%) were underweight and 301 (42.3%) were stunted. After treatment, among the 125 underweight children, WAZ improved in 69 patients, regained more than -2 on average. Among the 301 stunted children, HAZ improved in 123 patients, regained more than -2 on average. WAZ improved for the first 6 months by 0.052 units each month and then stabilized, whereas HAZ consistently improved by 0.014 units each month over time. Antiretroviral treatment reversed the adverse effects of HIV to some degree. Early diagnosis and treatment, with an effective nutrition program, is necessary to improve malnutrition further.

    Introduction Human immunodeficiency virus (HIV) infection is a primary cause of acquired heart disease, particularly of accelerated atherosclerosis, symptomatic heart failure, and pulmonary arterial hypertension. Cardiac complications often occur in late-stage HIV infections as prolonged viral infection is becoming more relevant as longevity improves. Thus, multi-agent HIV therapies that help sustain life may also increase the risk of cardiovascular events and accelerated atherosclerosis. Discussion Before highly active antiretroviral therapy (HAART), the two-to-five-year incidence of symptomatic heart failure ranged from 4 to 28% in HIV patients. Patients both before and after HAART also frequently have asymptomatic abnormalities in cardiovascular structure. Echocardiographic measurements indicate left ventricular (LV) systolic dysfunction in 18%, LV hypertrophy in 6.5%, and left atrial dilation in 40% of patients followed on HAART therapy. Diastolic dysfunction is also common in long-term survivors of HIV infection. Accelerated atherosclerosis has been found in HIV-infected young adults and children without traditional coronary risk factors. Infective endocarditis, although rare in children, has high mortality in late-stage AIDS patients with poor nutritional status and severely compromised immune systems. Although lymphomas have been found in HIV-infected children, the incidence is low and cardiac malignancy is rare. Rates of congenital cardiovascular malformations range from 5.6 to 8.9% in cohorts of HIV-uninfected and HIV-infected children with HIV-infected mothers. In non-HIV-infected infants born to HIV-infected mothers, foetal exposure to ART is associated with reduced LV dimension, LV mass, and septal wall thickness and with higher LV fractional shortening and contractility during the first two years of life. Conclusions Routine, systematic, and comprehensive cardiac evaluation, including a thorough history and directed laboratory assays, is essential for

    Objective To describe the pharmacokinetics of atazanavir (ATV) and ritonavir-boosted ATV/r in children ages 91 days to 21 years. Design Phase I/II, open label, multicenter study of once daily ATV and ATV/r as part of combination antiretroviral treatment in HIV-infected treatment experienced and naïve children. Setting Sites in the United States and South Africa. Subjects 195 children enrolled; 172 had evaluable ATV pharmacokinetics on day seven. Intervention Children were entered in age, dose and formulation (powder or capsule) cohorts. Intensive pharmacokinetic sampling occurred seven days after starting ATV. ATV doses were increased or decreased if the 24-hour area under the concentration time curves (AUC0–24hr) were <30 or >90 mcg*hr/mL, respectively. Main outcomes Cohorts satisfied protocol-defined pharmacokinetic criteria if the median ATV AUC0–24hr ≤60 mcg*hr/mL, and AUC0–24hr and ATV concentrations 24 hours post-dose (C24) were >30 mcg*hr/mL and ≥60 ng/mL, respectively, in ≥ 80% of children, with no individual AUC0–24hr <15 mcg*hr/mL. Results Unboosted ATV capsules satisfied pharmacokinetic criteria at a dose of 520 mg/m2 for those >2 to ≤ 13 years and 620 mg/m2 for those >13 to ≤ 21 years. ATV/r capsules satisfied criteria at a dose of 205 mg/m2 for those >2 to ≤ 21 years. ATV/r powder satisfied criteria at a dose of 310 mg/m2 for those >2 to ≤ 13 years, but pharmacokinetics in those ≤ 2 years were highly variable. Conclusions Body surface area-determined doses of ATV capsules and ATV/r powder and capsules provide ATV exposures in children >2 years that approximate values in adults receiving ATV/r.

    Human immunodeficiency virus (HIV) carries a high level of stigma to the HIV-infected individuals and their family members. Children of HIV-infected parents in China are particularly affected. The present study examined the relationship between associative stigma, self-esteem, optimism, anxiety and depression among 195 children of HIV-infected parents in rural China. Findings showed that more than one-third (35.4 %) of the participants scored higher than cut-off for depression; and 23.6-67.7 % of them scored higher than cut-off for different types of anxiety disorders. Structural equation modelling revealed that associative stigma had a significant negative relationship on self-esteem and optimism, which were associated with higher levels of depression and anxiety. The indirect effects of associative stigma on depression and anxiety were significant. The overall model showed a satisfactory fit. Findings suggest that associative stigma has a significant negative impact on mental health of children affected by HIV. Interventions to reduce their associative stigma are warranted. PMID:24879629

    Aim Lamivudine is used as first line therapy in HIV-infected children. Yet, like many other paediatric drugs, its dose rationale has been based on limited clinical data, without thorough understanding of the effects of growth on drug disposition. Here we use lamivudine to show how a comprehensive population pharmacokinetic model can account for the influence of demographic covariates on exposure (i.e. AUC and Cmax). Methods Data from three paediatric trials were used to describe the pharmacokinetics across the overall population. Modelling was based on a non-linear mixed effects approach. A stepwise procedure was used for covariate model building. Results A one compartment model with first order elimination best described the pharmacokinetics of lamivudine in children. The effect of weight on clearance (CL) and volume of distribution (V) was characterized by an exponential function, with exponents of 0.705 and 0.635, respectively. For a child with median body weight (17.6 kg), CL and V were 16.5 (95% CI 15.2, 17.7) l h−1 and 46.0 (95% CI 42.4, 49.5) l, respectively. There were no differences between formulations (tablet and solution). The predicted AUC(0,12 h) after twice daily doses of 4 mg kg−1 ranged from 4.44 mg l−1 h for children <14 kg to 7.25 mg l−1 h for children >30 kg. Conclusions The use of meta-analysis is critical to identify the correct covariate-parameter relationships, which must be assessed before a model is applied for predictive purposes (e.g. defining dosing recommendations for children). In contrast to prior modelling efforts, we show that the covariate distribution in the target population must be considered. PMID:24118070

    Background In HIV-infected children, viral diversity tends to increase with age in the absence of antiretroviral treatment (ART). We measured HIV diversity in African children (ages 6–36 months) enrolled in a randomized clinical trial comparing two ART regimens (Cohort I of the P1060 trial). Children in this cohort were exposed to single dose nevirapine (sdNVP) at birth. Methods HIV diversity was measured retrospectively using a high resolution melting (HRM) diversity assay. Samples were obtained from 139 children at the enrollment visit prior to ART initiation. Six regions of the HIV genome were analyzed: two in gag, one in pol, and three in env. A single numeric HRM score that reflects HIV diversity was generated for each region; composite HRM scores were also calculated (mean and median for all six regions). Results In multivariable median regression models using backwards selection that started with demographic and clinical variables, older age was associated with higher HRM scores (higher HIV diversity) in pol (P = 0.005) and with higher mean (P = 0.014) and median (P<0.001) HRM scores. In multivariable models adjusted for age, pre-treatment HIV viral load, pre-treatment CD4%, and randomized treatment regimen, higher HRM scores in pol were associated with shorter time to virologic suppression (P = 0.016) and longer time to study endpoints (virologic failure [VF], VF/death, and VF/off study treatment; P<0.001 for all measures). Conclusions In this cohort of sdNVP-exposed, ART-naïve African children, higher levels of HIV diversity in the HIV pol region prior to ART initiation were associated with better treatment outcomes.

    Some types of intravaginal practices (IVP) may increase the risk for HIV acquisition. This is particularly worrisome for populations with dual high prevalence of HIV and IVP. Women involved in transactional sex are at increased risk for HIV infection in sub-Saharan Africa. Social, cultural and economic influences are strong drivers of IVP in this population. To explore this, we carried out a qualitative research study to investigate the drivers and motivations for using IVP within a large observational study of women at high risk of HIV in Tanzania and Uganda from September 2008 to September 2009. Of the 201 women selected, 176 women took part in a semi-structured in-depth interview. Additionally, in Tanzania, eight focus group discussions among study participants and community members were carried out to obtain information on community norms and expectations. IVP were motivated by overlapping concerns with hygiene, morality, sexual pleasure, fertility, relationship security, and economic security. These motives were driven by the need to meet cultural and social expectations of womanhood, and at the same time attend to personal well-being. Among women involved in transactional sex in East Africa, interventions aimed at modifying or eliminating IVP should attend to local cultural and social norms as well as the individual as an agent of change.

    Objective To estimate the association of age of viral suppression and central nervous system penetration effectiveness (CPE) score with neurocognitive functioning among school-age children with perinatally-acquired HIV infection (PHIV+). Design We analyzed data from two U.S.-based multisite prospective cohort studies. Methods Multivariable general linear regression models were used to evaluate associations of age at viral suppression and CPE scores [of initial ART regimen and weighted average] with WISC-III or WISC-IV neurocognitive assessments [full scale IQ (FSIQ); performance IQ/ perceptual reasoning index (PIQ/PRI); and verbal IQ/ verbal comprehension index (VIQ/VCI)], adjusted for demographic and clinical covariates. Sensitivity analyses were stratified by birth cohort (before vs after 1996). Results 396 PHIV+ children were included. Estimated differences in mean FSIQ (comparing virally suppressed vs. unsuppressed children) by each age cutoff were 3.7, 2.2, 3.2, 4.4, and 3.9 points at ages 1, 2, 3, 4, and 5, respectively. For PIQ/PRI, estimated mean differences were 3.7, 2.4, 2.2, 4.6, and 4.5 at ages 1 through 5 respectively. In both cases, these differences were significant only at the age 4 and 5 thresholds. After stratifying by birth cohort the association between age at suppression and cognitive function persisted only among those born after 1996. Age at viral suppression was not associated with VIQ/VCI; CPE score was not associated with FSIQ, verbal comprehension or perceptual reasoning indices. Conclusions Virologic suppression during infancy or early childhood is associated with improved neurocognitive outcomes in school-aged PHIV+ children. In contrast, CPE scores showed no association with neurocognitive outcomes. PMID:25686678

    Grandparents throughout sub-Saharan Africa have shown immense courage and fortitude in providing care and support for AIDS-affected children. However, growing old comes with a number of challenges which can compromise the quality of care and support they are able to provide, particularly for children infected by HIV and enrolled on antiretroviral therapy (ART) programmes. For ART to be effective, and for infected children not to develop drug-resistance, a complex treatment regimen must be followed. Drawing on the perspectives of 25 nurses and eight grandparents of HIV-infected children in Manicaland, eastern Zimbabwe, we explore some of the challenges faced by grandparents in sustaining children's adherence to ART. These challenges, serving as barriers to paediatric ART, are poverty, immobility, deteriorating memory and poor comprehension of complex treatments. Although older HIV-infected children were found to play an active role in sustaining the adherence to their programme of treatment by contributing to income and food generating activities and reminding their guardians about check-ups and drug administration, such contribution was not available from younger children. There is therefore an urgent need to develop ART services that both take into consideration the needs of elderly guardians and acknowledge and enhance the agency of older children as active and responsible contributors to ART adherence.

    HIV affects the function of all lymphocyte populations, including B cells. Phenotypic and functional defects of B cells in HIV-infected adults have been well characterized, but defects in children have not been studied to the same extent. We determined the proportion of B cell subsets and frequencies of Ag-specific memory B cells in peripheral blood from HIV-infected children and healthy controls, using flow cytometry and B cell ELISPOT, respectively. In addition, we measured the quantities and avidities of plasma Abs against various Ags by ELISA. We also determined plasma levels of BAFF and expression of BAFF receptors on B cells. Children with high HIV viremia had increased proportions of activated mature B cells, tissue-like memory B cells and plasmablasts, and low proportions of naive B cells when compared with community controls and children with low HIV viremia, similar to adults infected with HIV. HIV-infected groups had lower proportions of resting memory B cells than did community controls. Notably, high HIV viremia prevented the age-dependent accumulation of class-switched resting memory B cells. HIV-infected children, regardless of the level of viremia, showed lower quantities and avidities of IgG and lower frequencies of memory B cells against Expanded Program on Immunization vaccines. The HIV-infected children had an altered BAFF profile that could have affected their B cell compartment. Therefore, B cell defects in HIV-infected children are similar to those seen in HIV-infected adults. However, control of HIV viremia is associated with normalization of activated B cell subsets and allows age-dependent accumulation of resting memory B cells. PMID:26116511

    Objective There are limited data on treatment-related anemia in Asian HIV-infected children. Methods Data from Asian HIV-infected children aged <18 years on first-line highly active antiretroviral therapy (HAART) were used. Children who had preexisting severe anemia at baseline were excluded. Anemia was graded by using the DAIDS 2004 table. Potential risk factors of severe anemia were assessed by logistic regression. Results Data from 1,648 children (51.9% female, 62.8% WHO stage 3/4) were analyzed. Median (IQR) age was 6.8 (3.7–9.6) years, CD4% was 9 (3–16)% and plasma HIV-RNA was 5.2 (4.7–5.6) log10 copies/ml at HAART initiation in those with available testing. The most common regimens were stavudine/lamivudine/nevirapine (42%) and zidovudine/lamivudine/nevirapine (25%). Severe anemia was identified in 47 (2.9%) children after a median time of 6 months after HAART initiation with an incidence rate of 5.4 per 100 child-years. Mild anemia or moderate anemia at baseline (p=0.024 and p=0.005, respectively), previous or current use of zidovudine (p<0.0001 and p=0.013, respectively), and male sex (p=0.008) were associated with severe anemia. Higher weight-for-age z-score (p=0.004) was protective. Conclusions The incidence of severe anemia in Asian HIV-infected children after HAART initiation was low and mainly occurred during the first few months after HAART initiation. Mild to moderate anemia at baseline and using AZT were independent risk factors of developing severe anemia. PMID:23764352

    In adults, nucleoside reverse transcriptase inhibitor (NRTI)-only antiretroviral regimens (NOARs) with ≥ three NRTIs are less potent than highly active antiretroviral therapy (HAART). However published pediatric experience with NOARs is limited. Methods We analyzed data from NOAR-treated participants in LEGACY, a multicenter observational cohort study of HIV-infected children and adolescents. NOAR-treated case-participantswere matched to participantswithout prior NOAR who initiated HAART during the same year for comparison. Results Of 575 participants with data from time of HIV diagnosis through 2006, 67 (12%) received NOARs for at least 24 weeks; most (46%) received the fixed dose combination of zidovudine/lamivudine/abacavir. NOAR use peaked in 2001-2002. NOAR-treated participants were significantly older and more treatment-experienced than HAART-treated participants. Virologic outcomes, including the percentage of participants with a plasma HIV RNA viral load <400 copies/mL at week 24 (47% vs. 34%) and the mean 24-week change in log10 plasma HIV RNA viral load from baseline (−0.63 vs. −1.02) were similar between NOAR- and HAART-treated participants, but virologic rebound was more likely in NOAR-treated participants (77% vs. 54%, P = 0.02). Increase in CD4 percentage points from baseline to 24 weeks was negligible in NOAR-treated participants compared with HAART-treated participants (0.95% vs. 10.1%, P <0.001). Anemia and leukopenia were more commonly reported with NOARs than HAART. Discussion Week 24 virologic outcomes were similar between NOAR- and HAART-treated participants, but NOAR durability was poorer and their use was associated with less immunologic reconstitution. NOARs should play a limited role in pediatric and adolescent ART. PMID:24008749

    Background Disclosure of the diagnosis of HIV to HIV-infected children is challenging for caregivers. Despite current recommendations, data suggest that levels of disclosure of HIV status to HIV-infected children receiving care in resource-limited settings are very low. Few studies describe the disclosure process for children in these settings, particularly the motivators, antecedent goals, and immediate outcomes of disclosure to HIV-infected children. This study examined caregivers' perception of the disclosure concept prior to disclosure, their motivation towards or away from disclosure, and their short- and long-term intentions for disclosure to their HIV-infected children. Methods In-depth interviews were conducted with primary caregivers of 40 HIV-infected children (ages 5–15 years) who were receiving HIV care but did not know their HIV status. Results Caregivers of HIV-infected children mainly perceived disclosure as a single event rather than a process of gradual delivery of information about the child's illness. They viewed disclosure as potentially beneficial both to children and themselves, as well as an opportunity to explain the parents' role in the transmission of HIV to the children. Caregivers desired to personally conduct the disclosure; however, most reported being over-whelmed with fear of negative outcomes and revealed a lack of self-efficacy towards managing the disclosure process. Consequently, most cope by deception to avoid or delay disclosure until they perceive their own readiness to disclose. Conclusions Interventions for HIV disclosure should consider that caregivers may desire to be directly responsible for disclosure to children under their care. They, however, need to be empowered with practical skills to recognize opportunities to initiate the disclosure process early, as well as supported to manage it in a phased, developmentally appropriate manner. The potential role for peer counselors in the disclosure process deserves further

    Abstract The impact of behavioral functioning on medication adherence in children with perinatally acquired HIV infection is not well-explored, but has important implications for intervention. This report addresses the relationship between behavioral functioning and child self-report or caregiver report of medication adherence among children and adolescents enrolled in Pediatric AIDS Clinical Trials Group Protocol 219C (conducted 2000–2007). A total of 1134 participants, aged 3–17 years, received a behavioral evaluation and adherence assessment. Complete adherence was defined as taking 100% of prescribed antiretroviral medications during three days preceding the study visit. Multivariable logistic regression models were used to evaluate associations between adherence and behavioral functioning, adjusting for potential confounders, including demographic, psychosocial, and health factors. Children demonstrated higher than expected rates of behavioral impairment (≈7% expected with T > 65) in the areas of conduct problems (14%, z = 7.0, p < 0.001), learning problems (22%, z = 12.2, p < 0.001), somatic complaints (22%, z = 12.6, p < 0.001), impulsivity-hyperactivity (20%, z = 11.1, p < 0.001), and hyperactivity (19%, z = 10.6, p < 0.001). Children with behavioral impairment in one or more areas had significantly increased odds of nonadherence [adjusted odds ratio (aOR) = 1.49, p = 0.04]. The odds of nonadherence were significantly higher for those with conduct problems and general hyperactivity (aOR = 2.03, p = 0.005 and aOR = 1.68, p = 0.02, respectively). Psychosocial and health factors, such as recent stressful life events and higher HIV RNA levels, were also associated with nonadherence. Knowledge of behavioral, health, and social influences affecting the child and family should guide the development of appropriate, evidence-based interventions for medication adherence.

    Background: Little is known about viral co-infections in African human immunodeficiency virus (HIV)-infected children. We examined the prevalence of seromarkers for cytomegalovirus (CMV), herpes simplex virus type 2 (HSV-2) and hepatitis B virus (HBV) infections among HIV-infected, antiretroviral treatment (ART)-naïve children in Lilongwe, Malawi. Methods: Ninety-one serum samples were tested for IgG and IgM antibodies to CMV, and IgG antibodies to HSV-2 and hepatitis B surface antigen (HBsAg). Baseline demographic, clinical and laboratory data were abstracted from electronic records. Results: CMV IgG was the most common positive result in all age groups (in 73% of children <1 year, and 100% in all other groups). Three patients were CMV IgM positive (3.3%), suggesting acute infection. HSV-2 IgG was positive in four patients (4.4%), and HBsAg in two (2.2%). Conclusions: CMV infection occurred early in life, and few children had specific signs of CMV infection at the time of ART initiation. Unrecognized HBV infection represents opportunities for testing and treatment of HIV/HBV co-infected children. PMID:26884443

    Objective Longitudinal studies objectively evaluating changes in regional fat distribution of HIV-infected children assessed by whole body dual energy X-ray absorptiometry (DEXA) are scarce, whilst this long-term effect of HIV and antiretroviral therapy (cART) is an important issue in infected children in need for lifelong treatment. Methods We assessed regional fat distribution over time, measured with sequential DEXA-scans in HIV-infected children on cART in cohorts from South Africa (SA) and the Netherlands (NL), and in healthy controls (SA). Limb and trunk fat Z-scores were calculated with the lambda-mu-sigma (LMS) method. Multivariable linear regression models with mixed effects were used to investigate the effect of cART compounds on body fat distribution over time. Results In total, 218 children underwent 445 DEXA assessments with a median follow-up of 3.5 years. Fat mass in all limbs was decreased in HIV-infected children compared to controls (arm fat Z-score: coefficient -0.4813; P = 0.006, leg fat Z-score: coefficient -0.4345; P = 0.013). In the HIV-infected group, stavudine treatment was associated with lower subcutaneous fat mass (arm fat Z-score: coefficient -0.5838; P = 0.001), with an additional cumulative exposure effect (arm fat Z-score: coefficient -0.0867; P = 0.003). Conclusions Our study shows that subcutaneous fat loss is still prevalent in HIV-infected children on cART, and is strongly associated with cumulative stavudine exposure. These results underline the need for early detection of subcutaneous fat loss and alternative treatment options for HIV-infected children globally. PMID:26148119

    Introduction Case control studies that assess the burden and factors associated with undernutrition and anaemia among HAART naïve HIV infected children in Nigeria is very sparse. This will help to formulate nutritional programs among these children. Methods Seventy HAART naive HIV infected children aged 18 months and above were as well as seventy age and sex matched HIV negative children were recruited from August 2007 to January 2009 at Paediatric Clinic of Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife, Nigeria. Their bio data, WHO clinical stage, anthropometric measurements, haematocrit, serum albumin and CD4 counts were taken with other parameters according to a study proforma. Results The prevalence of stunting, underweight and wasting among the HIV infected subjects were 48. 6%,58. 6% and 31. 4% respectively which as significantly higher than 28. 1%, 7. 1% and 28. 1% among the HIV negative controls. 20. 1% of the HIV infected children were marasmic compared to 2. 3% of the controls. Triple anthropometric failure was found in 7. 1% of the subjects as compared to none among the controls. Anaemia is significantly more prevalent among the subjects than the controls (70. 0% vs 31. 4%; p<0. 001). The prevalence of anaemia was higher in the HIV infected subjects with undernutrition. Low socioeconomic status, hypoalbuminemia and severe immunosuppression are significantly associated with higher undernutrition prevalence. Conclusion Several years after availability of HAART, undernutrition and anaemia remain widely prevalent among newly presenting HAART naïve HIV infected Nigerian children. Nutritional supplementation and evaluation for anaemia still need close attention in the management of these children. PMID:25400844

    The search for improvement of the health of systemically compromised patients and for a better knowledge about the impact of diseases on their lives has brought great interest for health-related quality of life, mainly in children with chronic diseases. The quality of life related to oral health is thus relevant, not only for being an inseparable component of the general health but also due to the importance of oral problems in the lives of these patients. The evaluation of oral health-related quality of life in HIV infected children can be of great importance seen that these patients show high prevalence of caries and periodontal diseases besides the oral manifestations of the virus infection itself. The aim of this article is to present some concepts about quality of life and the use of instruments for its evaluation on the basis of a literature review as well as to analyze the impact of oral health on the quality of life of HIV infected children.

    Backgrounds In Kenya, mathematical models estimate that there are approximately 220,000 children aged less than 15 years infected with HIV. We analyzed data from the second Kenya AIDS Indicator Survey (KAIS 2012) to estimate the prevalence of HIV infection among children aged 18 months to 14 years. Methods KAIS 2012 was a nationally representative 2-stage cluster sample household survey. We studied children aged 18 months to 14 years whose parents or guardians answered questions pertaining to their children by interview. Blood specimens were collected for HIV serology and viral load measurement. Results We identified 5162 children who were eligible for the study. Blood was obtained for 3681 (71.3%) children. Among child participants, 16.4% had been tested for HIV infection in the past, and among children with parents or guardians who self-reported HIV-positive status, 52.9% had been tested for HIV infection. Twenty-eight (0.9%) children tested HIV-positive in the survey. Of these, 11 had been previously diagnosed with HIV infection before the survey. All 11 children were in HIV care and receiving cotrimoxazole; 8 were on antiretorivral therapy (ART). Among those on ART, 4 were virologically suppressed. Conclusions HIV causes a substantial burden of disease in the Kenyan pediatric population. Although most children who had been diagnosed with HIV before the survey were engaged in care and treatment, they represented less than half of HIV-infected children identified in the survey. Future efforts should focus on identifying infected children and getting them into care and on suppressive ART as early as possible. PMID:24732823

    Quality of life (QOL) is an important antiretroviral treatment (ART) outcome. We compared QOL among 299 Thai and Cambodian children ages 1-12 years-old, CD4 15-24% randomized to early (ART at week 0, N=149) versus deferred groups (ART when at CD4 <15%, N=150) and also compared with QOL data from age-matched healthy controls (N=275). Primary caregivers completed PACTG QOL questionnaires at week 0 and every 24 weeks until 144 weeks. Children were enrolled during March 2006 to September 2008. Mean (SD) age of children was 6.3 (2.8) years, 58% were female, 60% were Thai, %CDC N:A:B:C was 2:62:36:0%. During 144 weeks, all children in the early-group and 69 (46%) of deferred-group children started ART. There was no significant difference of QOL scores between treatment groups at baseline (all p>0.05) and at week 144 (all p>0.05). By multivariate analysis, the early-group had higher QOL score changes in five domains, including health perception (p=0.04), physical resilience (p=0.02), psychosocial well-being (p=0.04), social and role functioning (p<0.01), and symptoms (p=0.01) compared to the deferred group. QOL of HIV-infected children in both groups were lower than healthy control in all 7 domains at baseline (all p<0.05) and 5 of 7 domains at weeks 144 (p<0.01). In conclusion, no significant difference of QOL scores between treatment groups. Early ART commencement associated with greater increase of QOL scores over 144 weeks. QOL scores in HIV-infected children were lower than healthy controls. PMID:24191673

    It is important to consider the complexities of family dynamics when deciding when and how to communicate with HIV-infected children about their illness and treatment. Previous research has focused on providers' and caregivers' perspectives on whether, when and how to disclose HIV/AIDS diagnosis and treatment to HIV-infected children. From the perspective of HIV-infected children, communication does not mean just giving information about illness and treatment, but also encompasses emotional and material care. This paper places communication within the broader framework of caregiving in family situations. This exploratory study was conducted in Jinja district, Uganda, between November 2011 and December 2012. Through participant observation and in-depth interviews, communication by, and with, HIV-infected children in the context of family situations was explored from the perspectives of 29 HIV-infected children aged 8-17 years on antiretroviral therapy (ART) using content thematic analysis. Children's communication with caregivers about their illness and treatment varied depending on whom they were living with and the nature of caregiving. Although a mother's care was considered best, children described others who cared 'like a mother'. For some, caregiving was distributed among several relatives and non-relatives, while others felt they had hardly anyone to care for them. Caregiving from the children's perspective involved emotional support, expressed verbally and explicitly in messages of concern, encouragement conveyed in reminders to take medicines, attention when sick and confidential conversations about the challenges of having HIV and taking ART. Caregiving was also communicated implicitly in acts of provision of food/drinks to take with medicines, counting pills to confirm they had taken the medicines and accompanying children to treatment centres. Children's communication about their health and medicines and the care they received was to a large extent

    Background Deficiencies in antioxidants contribute to immune dysregulation and viral replication. Objective To evaluate the correlation of selenium (Se) and zinc (Zn) levels on the treatment outcomes in HIV-infected children. Design HIV-infected Thai children 1–12 years old, CD4 15–24%, without severe HIV symptoms were included. Se and Zn levels were measured by graphite furnace atomic absorption spectrometry at baseline and 48 weeks. Deficiency cut-offs were Se<0.1 μmol/L and Zn<9.9 μmol/L. Serum ferritin and C-reactive protein (CRP) were performed every 24 weeks. No micronutrient supplement was prescribed. Results 141 children (38.3% male) with a median (IQR) age of 7.3 (4.2–9.0) years, were enrolled. Median baseline CD4% was 20%, HIV-RNA was 4.6 log10copies/mL. At baseline, median (IQR) Se and Zn levels were 0.9 (0.7–1.0) μmol/L and 5.9 (4.8–6.9) μmol/L, respectively. None had Se deficiency while all had Zn deficiency. Over 48 weeks, 97 initiated antiretroviral therapy (ART) and 81% achieved HIV-RNA <50 copies/mL with 11% median CD4 gain. The mean change of Se was 0.06 μmol/L (p = 0.003) and Zn was 0.42 μmol/L (p=0.003), respectively. By multivariate analysis in children who received ART, predictors for greater increase of CD4% from baseline were lower baseline CD4% (p<0.01) and higher baseline Zn level (p=0.02). The predictors for greater decrease of HIV-RNA from baseline were higher baseline HIV-RNA and higher ferritin (both p<0.01). No association of CRP to the changes from baseline of CD4% or HIV-RNA was found. Conclusion In HIV-infected Thai children without severe immune deficiency who commenced ART, no correlation between selenium and ART treatment outcomes were found. Higher pre-ART Zn levels were associated with significant increases in CD4 percent at 48 weeks. PMID:22713768

    Background Hepatitis B virus (HBV) is an important cause of comorbidity in human immunodeficiency virus (HIV)–infected individuals. The immunogenicity of HBV vaccination in children receiving highly active antiretroviral therapy (HAART) was investigated. Methods HIV-infected children receiving HAART who had low to moderate HIV loads and who had previously received ≥3 doses of HBV vaccine were given an HBV vaccine booster. Concentrations of antibody to hepatitis B surface antigen (anti-HBs) were determined before vaccination and at weeks 8, 48, and 96. A subset of subjects was administered a subsequent dose, and anti-HBs was measured before and 1 and 4 weeks later. Results At entry, 24% of 204 subjects were seropositive. Vaccine response occurred in 46% on the basis of seropositivity 8 weeks after vaccination and in 37% on the basis of a ≥4-fold rise in antibody concentration. Of 69 subjects given another vaccination 4–5 years later, immunologic memory was exhibited by 45% on the basis of seropositivity 1 week after vaccination and by 29% on the basis of a ≥4-fold rise in antibody concentration at 1 week. Predictors of response and memory included higher nadir and current CD4 cell percentage, higher CD19 cell percentage, and undetectable HIV load. Conclusions HIV-infected children frequently lack protective levels of anti-HBs after previous HBV vaccination, and a significant proportion of them do not respond to booster vaccination or demonstrate memory despite receiving HAART, leaving this population insufficiently protected from infection with HBV.

    Human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) has a profound impact not only on the infected individuals, but also on their families. Children of the HIV-infected parents are particularly affected. The present study examined the relationship between social support, resilience, posttraumatic growth (PTG), hopelessness, and depression among 195 children of HIV-infected parents in mainland China. Results showed that 35.4% of the sample scored above the cutoff of the Children's Depression Inventory. Results from structural equation modeling reported that social support had a significant positive relationship with resilience and PTG. Higher levels of resilience and PTG were associated with lower level of hopelessness which in turn, was associated with lower level of depression. The overall model achieved satisfactory fit. Interventions are needed to improve social support of the children affected by HIV so as to improve their mental health. PMID:24922584

    This study aimed to evaluate the adherence to an Oral Health Program (OHP) for HIV infected children and adolescents, as well as the attitudes of their caretakers regarding oral care. A total of 58 caretakers that accompany the children in medical appointments at an AIDS ambulatory were interviewed for collecting personal data and data regarding adherence to the OHP or other odontological treatment and attitudes related to oral care. Approximately 70% of the caretakers stated that their children participated in the OHAP, however 20% of them did not return to the recall appointments; such visits were even less frequent when the caretakers were not the parents themselves (p= 0.036). The adherence of this population to dental treatment outside the OHP was small, 48% of the caretakers stated that the child did not conclude the treatment when referred to another place for treatment. The attitude of the caretakers regarding dental care of HIV+ children was not considered satisfactory. Furthermore, it is very important to have pediatric dentists in the multi-professional teams that attend HIV+ children and adolescents and to promote this program among the parents and all medical teams involved with such patients.

    Background Previously, HIV epidemic models have used a double Weibull curve to represent high initial and late mortality of HIV-infected children, without distinguishing timing of infection (peri- or post-natally). With more data on timing of infection, which may be associated with disease progression, a separate representation of children infected early and late was proposed. Methods Paediatric survival post-HIV infection without anti-retroviral treatment was calculated using pooled data from 12 studies with known timing of HIV infection. Children were grouped into perinatally or post-natally infected. Net mortality was calculated using cause-deleted life tables to give survival as if HIV was the only competing cause of death. To extend the curve beyond the available data, children surviving beyond 2.5 years post infection were assumed to have the same survival as young adults. Double Weibull curves were fitted to both extended survival curves to represent survival of children infected perinatally or through breastfeeding. Results Those children infected perinatally had a much higher risk of dying than those infected through breastfeeding, even allowing for background mortality. The final-fitted double Weibull curves gave 75% survival at 5 months after infection for perinatally infected, and 1.1 years for post-natally infected children. An estimated 25% of the early infected children would still be alive at 10.6 years compared with 16.9 years for those infected through breastfeeding. Conclusions The increase in available data has enabled separation of child mortality patterns by timing of infection allowing improvement and more flexibility in modelling of paediatric HIV infection and survival.

    Objective To demonstrate the utility of a medical terminology-based method for identifying cases of possible mitochondrial dysfunction (MD) in a large cohort of youths with perinatal HIV infection and to describe the scoring algorithms. Methods Medical Dictionary for Regulatory Activities (MedDRA)® version 6 terminology was used to query clinical criteria for mitochondrial dysfunction by two published classifications, the Enquête Périnatale Française (EPF) and the Mitochondrial Disease Classification (MDC). Data from 2,931 participants with perinatal HIV infection on PACTG 219/219C were analyzed. Data were qualified for severity and persistence, after which clinical reviews of MedDRA-coded and other study data were performed. Results Of 14,000 data records captured by the EPF MedDRA query, there were 3,331 singular events. Of 18,000 captured by the MDC query, there were 3,841 events. Ten clinicians blindly reviewed non MedDRA-coded supporting data for 15 separate clinical conditions. We used the Statistical Analysis System (SAS) language to code scoring algorithms. 768 participants (26%) met the EPF case definition of possible MD; 694 (24%) met the MDC case definition, and 480 (16%) met both definitions. Limitations Subjective application of codes could have affected our results. MedDRA terminology does not include indicators of severity or persistence. Version 6.0 of MedDRA did not include Standard MedDRA Queries, which would have reduced the time needed to map MedDRA terms to EPF and MDC criteria. Conclusion Together with a computer-coded scoring algorithm, MedDRA terminology enabled identification of potential MD based on clinical data from almost 3000 children with substantially less effort than a case by case review. The article is accessible to readers with a background in statistical hypothesis testing. An exposure to public health issues is useful but not strictly necessary. PMID:23797349

    Objective To understand the health status of HIV orphans in a well-structured institutional facility in India. Method Prospective longitudinal analysis of growth and anaemia prevalence among these children, between June 2008 and May 2011. Results A total of 85 HIV-infected orphan children residing at Sneha Care Home, Bangalore, for at least 1 year, were included in the analysis. Prevalence of anaemia at entry into the home was 40%, with the cumulative incidence of anaemia during the study period being 85%. At baseline, 79% were underweight and 72% were stunted. All children, irrespective of their antiretroviral therapy (ART) status, showed an improvement in nutritional status over time as demonstrated by a significant increase in weight (median weight-for-age Z-score: −2.75 to −1.74, P < 0.001) and height Z-scores (median height-for-age Z-score: −2.69 to −1.63, P < 0.001). Conclusion These findings suggest that good nutrition even in the absence of ART can bring about improvement in growth. The Sneha Care Home model indicates that the holistic approach used in the Home may have been helpful in combating HIV and poor nutritional status in severely malnourished orphaned children.

    Background. Response rates and immunologic memory following measles vaccination are reduced in human immunodeficiency virus (HIV)–infected children in the absence of highly active antiretroviral therapy (HAART). Methods. HIV-infected children 2 to <19 years old receiving HAART and with HIV loads <30 000 copies/mL, CD4% ≥15, and ≥1 prior measles-mumps-rubella vaccination (MMR) were given another MMR. Measles antibody concentrations before and 8, 32, and 80 weeks postvaccination were determined by plaque reduction neutralization (PRN). A subset was given another MMR 4–5 years later, and PRN antibody was measured before and 7 and 28 days later. Results. At entry, 52% of 193 subjects were seroprotected (PRN ≥120 mIU/mL). Seroprotection increased to 89% 8 weeks postvaccination, and remained at 80% 80 weeks postvaccination. Of 65 subjects revaccinated 4–5 years later, 85% demonstrated memory based on seroprotection before or 7 days after vaccination. HIV load ≤400 copies/mL at initial study vaccination was associated with higher seroprotection rates, greater antibody concentrations, and memory. Grade 3 fever or fatigue occurred in 2% of subjects. Conclusions. Measles revaccination induced high rates of seroprotection and memory in children receiving HAART. Both endpoints were associated with HIV viral load suppression.

    Background Preliminary evidence suggests that improved nutrition early in HIV infection may delay progression to AIDS and delay the initiation or improve the effectiveness of antiretroviral drug therapy. There are few studies that evaluate food-based interventions in drug-naïve, HIV-infected women and their children. Meat provides several nutrients identified as important in maintaining immune function and lean body mass. Objective To design supplemental meat and soybean biscuits for use in a randomized trial examining the effect of meat in the diet of drug-naïve, HIV-infected rural Kenyan women on changes in weight, lean body mass, morbidity, nutritional status, and activities of daily living of the women and growth and development of their children. Methods We designed three supplemental biscuits: one with added dried beef, another with added soybean flour, and a wheat biscuit to serve as a control biscuit to be used in a randomized feeding intervention in drug-naïve, HIV-infected rural Kenyan women and their children. The nutritional contents of the different types of biscuit were examined and compared. Results The three biscuits were isocaloric. Meat biscuits provided more lysine, vitamin B12, and bioavailable zinc. Soybean biscuits provided more total and absorbable iron; however, higher fiber and phytate contents may inhibit nutrient absorption. Data analysis for clinical outcomes of the trial is ongoing. Conclusions The “biscuit model” is useful for nutrition supplementation studies because it can be provided in a blinded and randomized fashion, safely and privately in a home under directly observed consumption by a highly stigmatized population. It is well received by adults and children, and the biscuits can be produced locally with available, simple, affordable technology. PMID:25639139

    Aim Little attention has been paid to the effects of compliance and prescription practice on treatment outcome in HIV-infected children. In this context, an evaluation of the role of covariates on pharmacokinetics is required to establish the impact of differences in dosing regimens. Here we investigate whether a once daily dosing regimen of lamivudine provides comparable exposure to the currently approved paediatric regimen. Methods A hypothetical group of 180 patients between 3 months and 12 years old was used to evaluate the impact of body weight on systemic exposure to lamivudine. Simulation scenarios were evaluated using AUC and Cmax as parameters of interest. The analysis was performed using a population pharmacokinetic model previously implemented in nonmem v.6.2. Results The simulations show that once daily dosing of lamivudine yields comparable exposure to historical values observed in children and adults, both for liquid and solid dosage forms. Simulated steady-state AUC(0–24 h) and Cmax values after once daily doses ranged respectively from 9.95 mg l−1 h and 1.9 mg l−1 for children lighter than 14 kg to 13.75 mg l−1 h and 3.0 mg l−1 for children heavier than 30 kg. These values are comparable or higher than historical values observed after once daily dosing in children and adults. Conclusions Our findings illustrate how dosing regimens can be evaluated taking into account the effects of developmental growth on drug disposition. Most importantly, they suggest that the reduction in dosing frequency to once daily leads to comparable lamivudine exposure, as observed after administration of a twice daily dosing regimen.

    Background There are limited data on opportunistic infections (OI) and factors associated with their occurrence after highly active antiretroviral therapy (HAART) in Asian children. The use of HAART in Asia started much later than in developed countries and therefore reported findings may not be fully applicable to the pediatric HIV epidemic in Asia. Methods Retrospective and prospectively collected data from the TREAT Asia Pediatric HIV Observational Database cohort study from March 1993 to March 2009 were analyzed. OIs were defined according to WHO clinical staging criteria, and incidence rates calculated. Factors associated with the incidence of severe OIs were analyzed using random effects Poisson regression modeling. Results Of 2280 children in the cohort, 1752 were ever reported to have received ART, of whom 1480 (84%) started on HAART. Before commencing any ART, OIs occurred at a rate of 89.5 per 100 person-years. The incidence rate was 28.8 infections per 100 person-years during mono- or dual-therapy, and 10.5 infections per 100 person-years during HAART. The most common OIs both before and after ART initiation were recurrent upper respiratory tract infections, persistent oral candidiasis, and pulmonary tuberculosis. The incidence rates of WHO clinical stage 3 or 4 OIs after HAART were highest among children <18 months of age and those with low weight-for-age z scores, CD4 cell percentage <15%, and WHO stage 3 at HAART initiation. Conclusions Despite dramatic declines in their incidence, OIs remained important causes of morbidity after HAART initiation in this regional cohort of HIV-infected children in Asia. PMID:24378942

    Millions of children in Sub-Saharan Africa live with adults, often parents, who are HIV-infected or ill due to AIDS. These children experience social, emotional, and health vulnerabilities that overlap with, but are not necessarily the same as, those of orphans or other vulnerable children. Despite their distinctive vulnerabilities, research aimed at understanding the situation of these children has been limited until very recently. This review summarizes the state of knowledge based on a systematic search of PubMed and Web of Science that identified 47 empirical research articles that examined either the population prevalence of children living with HIV-infected or AIDS-sick adults, or the consequences of adult HIV infection or AIDS illness for child well-being. This review confirms that this population of children is substantial in size, and that the vulnerabilities they experience are multi-faceted, spanning physical and emotional health and schooling. Mechanisms were examined empirically in only a small number of studies, but encompass poverty, transmission of opportunistic infections, care for unwell adults, adult distress, AIDS stigma, lack of social support, maternal breastfeeding issues, and vertical HIV transmission. Some evidence is provided that infants, adolescents, children with infected or ill mothers, and children living with severely ill adults are particularly vulnerable. Future research would benefit from more attention to causal inference and further characterization of processes and circumstances related to vulnerability and resilience. It would also benefit from further study of variation in observed associations between adult HIV/AIDS and child well-being based on characteristics such as age, sex, kinship, severity of illness, TB co-infection, disclosure, and serostatus awareness. Almost one-quarter of the studies reviewed did not investigate variation based on any of these factors. More nuanced understanding of the short- and long

    Retaining subjects from disadvantaged populations in long-term studies is necessary to obtain high-quality data. This article presents cumulative retention rates from a 5-year prospective cohort study, the Pediatric Pulmonary and Cardiovascular Complications of Vertically Transmitted HIV Infection study. It also presents results of a cross-sectional qualitative survey about factors that induced caregivers to stay in the study. Although the repeated study visits were long and uncomfortable, cumulative retention among the 298 HIV-infected children was 80%. Incentives considered important by the caregivers included phone contact with nurse coordinators, nurse coordinators accompanying the caregiver and child during visits, phone reminders for appointments, help with scheduling, meals and transportation, access to health care, and relationships with staff. Thus, the high follow-up rate was in part due to nurses’ efforts to reduce the study’s burden on the families, provide tangible and intangible incentives, and establish personal relationships with families.

    Objective Medication adherence is critical to the success of antiretroviral therapies for children and youth with perinatally acquired HIV. Factors that influence successful transition of medication responsibility from caregivers to youth are poorly understood. The purpose of this study was to evaluate the relationship of medication adherence with demographic, cognitive, academic, and behavioral characteristics. Method Randomly selected youth, N = 151, age 8-18, completed cognitive and academic measures, and they and their caregivers completed questionnaires assessing behavior and emotional well-being. An announced pill count and questionnaires completed by youth and their caregivers were used to evaluate adherence. Results Of 151 participants, 100 completed all adherence measures. Adherence rates varied by assessment method. Non-adherence (<90%) by pill count was associated with older child age, greater youth responsibility for medications, and other demographic and medication regimen variables. Verbal impairment predicted better self-reported adherence and reading problems predicted better self- and caregiver-reported adherence. Youth-reported locus of control was associated with pill count non-adherence, and poor relationships with parents were associated with youth-reported non-adherence. Conclusion Consideration of youth cognitive or academic status may be helpful in evaluating medication adherence in patients with perinatally acquired HIV infection, particularly when using self- or caregiver reports to assess adherence. Vigilance for adherence problems is indicated when youth are older, responsible for medications, report poor caregiver relationships, and/or sense a lack of control over their lives. PMID:22366661

    OBJECTIVE: To determine whether children aged 3-59 months with mild or non-symptomatic human immunodeficiency virus (HIV) infection and WHO-defined severe pneumonia have a higher failure rate than do HIV-uninfected children when treated with the standard WHO treatment of parenteral penicillin or oral amoxicillin. METHODS: This study was a planned sub-analysis of a randomized trial of 3-59-month-old children presenting with WHO-defined severe pneumonia (the APPIS study). We included two sites with high HIV prevalence in Durban, South Africa and Ndola, Zambia. Primary outcome measures were clinical treatment failure at day 2 and day 14. CLINICALTRIALS.GOV IDENTIFIER: CT00227331http://www.clinicaltrialsgov/show/NCT00227331). FINDINGS: Of the 523 children enrolled, HIV status was known for 464 participants; 106 (23%) of these were infected with HIV. By day 2, 57 (12.3%) children had failed treatment and 110 (23.7%) failed by day 14. Twenty (18.9%) HIV-infected children failed by day 2 compared with 37 (10.3%) uninfected children (adjusted odds ratio (OR) 2.07; 95% confidence interval (CI): 1.07-4.00). Thirty-four (32.1%) HIV-infected children failed treatment by day 14 compared with 76 (21.2%) uninfected children (adjusted OR 1.88; 95% CI: 1.11-3.17). Analysis stratified by age showed that the greatest differential in treatment failure at day 2 and day 14 occurred in the children aged 3-5 months. CONCLUSIONS: HIV-infected children with severe pneumonia fail WHO-standard treatment with parenteral penicillin or amoxicillin at day 2 and day 14 more often than do HIV-uninfected children, especially young infants. Standard case management of acute respiratory infection (ARI) using WHO treatment guidelines is inadequate in areas of high HIV prevalence and reappraisal of empiric antimicrobial therapy is urgently needed for severe pneumonia associated with HIV-1.

    The perspectives and practices of health care workers (HCWs) regarding disclosure to HIV-infected children have not been adequately investigated ten years after the roll-out of pediatrics antiretroviral therapy (ART). The aim of the study was to examine the opinions of HCWs about disclosure to HIV-infected children and determine their role in disclosure to children accessing ART in health centers in South Africa. This was a cross-sectional survey using a semi-structured questionnaire among HCWs in ART centers at three hospitals and 48 primary health facilities in two provinces in South Africa. Of the 206 HCWs, 140 (68.2%) were nurses, 44 (21.5%) were lay counsellors, and 4 (2%) were doctors. The majority (n = 183, 89.3%) felt that disclosure benefits children and they should be told about their HIV status. Over half (n = 93, 51.4%) recommended 11–18 years as the appropriate age to disclose. Half (n = 99, 48.5%) said that caregivers should take the lead to disclose, 87 (42.7%) said that disclosure is a shared responsibility of caregivers and HCWs, and 18 (8.8%) said HCWs should lead disclosure. HCWs perceived their role as that of preparing the caregiver for disclosure and the child to understand the disease. However, the lack of guidelines and training on disclosure counselling for children affects their ability to fully participate in disclosure to children. There is a need to adopt the World Health Organizations’ disclosure guidelines for children and adapt them to the local cultural and community contexts and train HCWs to guide, support, and assist caregivers in their disclosure to HIV-infected children.

    The Pediatric HIV/AIDS Cohort Study (PHACS), the largest ongoing longitudinal study of perinatal HIV-infected (PHIV) and HIV-exposed, uninfected (PHEU) children in the United States, comprises the Surveillance Monitoring of Antiretroviral Therapy [ART] Toxicities (SMARTT) Study in PHEU children and the Adolescent Master Protocol (AMP) that includes PHIV and PHEU children ≥7 years. Although race/ethnicity is often used to assess health outcomes, this approach remains controversial and may fail to accurately reflect the backgrounds of ancestry-diverse populations as represented in the PHACS participants.In this study, we compared genetically determined ancestry (GDA) and self-reported race/ethnicity (SRR) in the PHACS cohort. GDA was estimated using a highly discriminative panel of 41 single nucleotide polymorphisms and compared to SRR. Because SRR was similar between the PHIV and PHEU, and between the AMP and SMARTT cohorts, data for all unique 1958 participants were combined.According to SRR, 63% of study participants identified as Black/African-American, 27% White, and 34% Hispanic. Using the highest percentage of ancestry/ethnicity to identify GDA, 9.5% of subjects were placed in the incorrect superpopulation based on SRR. When ≥50% or ≥75% GDA of a given superpopulation was required, 12% and 25%, respectively, of subjects were placed in the incorrect superpopulation based on SRR, and the percent of subjects classified as multiracial increased. Of 126 participants with unidentified SRR, 71% were genetically identified as Eurasian.GDA provides a more robust assessment of race/ethnicity when compared to self-report, and study participants with unidentified SRR could be assigned GDA using genetic markers. In addition, identification of continental ancestry removes the taxonomic identification of race as a variable when identifying risk for clinical outcomes. PMID:27603370

    Background The true prevalence of HIV and other sexually transmitted diseases among street children in Nepal is virtually unknown while information on related behavioural risk factors in this population is non-existent. The risk of HIV infection among street children and adolescents may be especially high due to their marginalized social and economic conditions. This study was conducted to determine the prevalence of HIV infection among a sample of street children and youth of Kathmandu and to identify risk factors associated with HIV infection in this group. A sample of street children and youth was recruited based on the purposive sampling of ten streets in Kathmandu, Nepal, known to have a high density of street children and youth. A total of 251 street children (aged 11–16 years) and youth (aged 17–24 years) were enrolled, with informed consent, from November, 2008 through June, 2009. Most of the participants (95%) were male. Case status was determined by serological assessment of HIV status; data on risk factors were obtained using structured survey interviews. HIV prevalence and rates of a number of behavioural risk factors suspected to play a role in HIV transmission among street children and youth were determined, including unprotected sex, intravenous drug use, and other risky sex and substance use behaviours. Results Among the 251 children and youth, we found an overall HIV prevalence of 7.6%. As the sample size of females was small (n = 13) and the behavioural risk factors are likely to be quite different for boys and girls, we conducted separate analyses by gender. As our small sample of females is unlikely to be representative and lacks power for statistical testing, our report focuses on the results for the males surveyed.The strongest behavioural risk factor to emerge from this study was intravenous drug use; 30% of the male subjects were injecting drug users and 20% of those were HIV positive. Furthermore, frequency of drug injection was

    Infection with HIV, and oftentimes coinfection with TB, complicates the care of severely malnourished children in sub-Saharan Africa. These superimposed infections challenge clinicians faced with a population of malnourished children for whose care evidence-based guidelines have not kept up. Even as the care of HIV-uninfected malnourished children has improved dramatically with the advent of community-based care and even as there are hopeful signs that the HIV epidemic may be stabilizing or ameliorating, significant gaps remain in the care of malnourished children with HIV. Here we summarize what is currently known, what remains unknown, and what remains challenging about how to treat severely malnourished children with HIV and TB. PMID:22606378

    Introduction The World Health Organization (WHO) 2010 guidelines recommended to treat all HIV-infected children less than two years of age. We described the inclusion process and its correlates of HIV-infected children initiated on early antiretroviral therapy (EART) at less than two years of age in Abidjan, Côte d'Ivoire, and Ouagadougou, Burkina Faso. Methods All children with HIV-1 infection confirmed with a DNA PCR test of a blood sample, aged less than two years, living at a distance less than two hours from the centres and whose parents (or mother if she was the only legal guardian or the legal caregiver if parents were not alive) agreed to participate in the MONOD ANRS 12206 project were included in a cohort to receive EART based on lopinavir/r. We used logistic regression to identify correlates of inclusion. Results Among the 217 children screened and referred to the MONOD centres, 161 (74%) were included and initiated on EART. The main reasons of non-inclusion were fear of father's refusal (48%), mortality (24%), false-positive HIV infection test (16%) and other ineligibility reasons (12%). Having previously disclosed the child's and mother's HIV status to the father (adjusted odds ratio (aOR): 3.20; 95% confidence interval (95% CI): 1.55 to 6.69) and being older than 12 months (aOR: 2.05; 95% CI: 1.02 to 4.12) were correlates of EART initiation. At EART initiation, the median age was 13.5 months, 70% had reached WHO Stage 3/4 and 57% had a severe immune deficiency. Conclusions Fear of stigmatization by the father and early competing mortality were the major reasons for missed opportunities of EART initiation. There is an urgent need to involve fathers in the care of their HIV-exposed children and to promote early infant diagnosis to improve their future access to EART and survival. PMID:27015798

    Abstract A multicenter, retrospective, observational study was conducted to determine prevalence, characteristics, management, and outcome of pulmonary tuberculosis (PTB) in Asian HIV-infected children in the TREAT Asia Pediatric HIV Observational Database (TApHOD). Data on PTB episodes diagnosed during the period between 12 months before antiretroviral therapy (ART) initiation and December 31, 2009 were extracted. A total of 2678 HIV-infected children were included in TApHOD over a 13-year period; 457 developed PTB, giving a period prevalence of 17.1% (range 5.7–33.0% per country). There were a total of 484 PTB episodes; 27 children had 2 episodes each. There were 21 deaths (4.3%). One third of episodes (n=175/484) occurred after ART initiation at a median of 14.1 months (interquartile range [IQR] 2.5–28.8 months). The median (IQR) CD4+ values were 9.0% (3.0–16.0%) and 183.5 (37.8–525.0) cells/mm3 when PTB was diagnosed. Most episodes (n=424/436, 97.3%) had abnormal radiographic findings compatible with PTB, whereas half (n=267/484, 55.2%) presented with clinical characteristics of PTB. One third of those tested (n=42/122, 34.4%) had bacteriological evidence of PTB. Of the 156 episodes (32.2%) that were accompanied with extrapulmonary TB, pleuritis was the most common manifestation (81.4%). After treatment completion, most episodes (n=396/484, 81.9%) were recorded as having positive outcomes (cured, treatment completed and child well, and improvement). The prevalence of PTB among Asian HIV-infected children in our cohort was high. Children with persistent immunosuppression remain vulnerable to PTB even after ART initiation. PMID:24206012

    World Health Organization and United Nations International Children's Emergency Fund have strongly recommended a sustained coverage of universal immunisation among all children against tuberculosis, polio, diphtheria, pertussis, tetanus and measles. In India, these vaccines under the universal immunisation programme are made available absolutely free of cost to all children through the public health system. Information regarding immunisation coverage among HIV exposed children in India is still very limited. The objective of this study was to estimate the proportion of children of people living with HIV who had been completely immunised by the age of 12 months and to find predictors of complete immunisation. A community-based cross-sectional survey was conducted in the Kolkata Metropolitan Area between 15 June and 14 September 2009 using a pre-structured interview schedule. Data were analysed from 256 care-givers of children (85.5% response rate) whose parents were randomly selected from the Bengal Network of HIV-positive people. Multiple logistic regression was used to estimate and test associations of predictors with complete immunisation. The percentage of children of people living with HIV completely immunised at the age of 12 months was 73.0% (67.3% to 78.1%), which was not significantly different from that for all children at 12 months. Mothers having received antenatal care [OR (odds ratio): 7.29; 95% confidence intervals (CI): 2.39-22.25], mothers having postprimary education (OR: 3.37; 95% CI: 1.45-7.81), children of Hindu and Christian religion (OR: 3.74; 95% CI: 1.63-8.62), children not belonging to scheduled castes, tribes and 'other backward classes' (OR: 2.08; 95% CI: 1.02-4.25) were significant independent predictors of complete immunisation status of these children. This emphasises the imperative need for up-scaling of antenatal care among the pregnant mothers to ensure complete immunisation among their children. A special focus on girl child

    Background While studies of HIV-infected adults on antiretroviral treatment (ART) report no sex differences in immune recovery and virologic response but more ART-associated complications in women, sex differences in disease progression and response to ART among children have not been well assessed. The objective of this study was to evaluate for sex differences in response to ART in South African HIV-infected children who were randomized to continue ritonavir-boosted lopinavir (LPV/r)-based ART or switch to nevirapine-based ART. Methods ART outcomes in HIV-infected boys and girls in Johannesburg, South Africa from 2005–2010 were compared. Children initiated ritonavir-boosted lopinavir (LPV/r)-based ART before 24 months of age and were randomized to remain on LPV/r or switch to nevirapine-based ART after achieving viral suppression. Children were followed for 76 weeks post-randomization and then long-term follow up continued for a minimum of 99 weeks and maximum of 245 weeks after randomization. Viral load, CD4 count, lipids, anthropometrics, drug concentrations, and adherence were measured at regular intervals. Outcomes were compared between sexes within treatment strata. Results A total of 323 children (median age 8.8 months, IQR 5.1-13.5), including 168 boys and 155 girls, initiated LPV/r-based ART and 195 children were randomized. No sex differences in risk of virological failure (confirmed viral load >1000 copies/mL) by 156 weeks post-randomization were observed within either treatment group. Girls switched to nevirapine had more robust CD4 count improvement relative to boys in this group through 112 weeks post-randomization. In addition, girls remaining on LPV/r had higher plasma concentrations of ritonavir than boys during post-randomization visits. After a mean of 3.4 years post-randomization, girls remaining on LPV/r also had a higher total cholesterol:HDL ratio and lower mean HDL than boys on LPV/r. Conclusions Sex differences are noted in

    Abstract Non-nucleoside reverse transcriptase inhibitors (NNRTIs) are commonly used in pediatric patients; however, rapid development of resistance, due to non-adherence and cross-resistance, results in their discontinuation and limits their recycling. We evaluated the clinical experience of recycling NNRTIs despite documented NNRTI resistance (NNRTI-R), and examined virologic and CD4 cell count outcomes among participants enrolled in Longitudinal Epidemiologic Study to Gain Insight into HIV/AIDS in Children and Youth (LEGACY), a national HIV-infected pediatric cohort. We conducted a retrospective analysis of LEGACY participants with major NNRTI-R. Using chi-square analyses and logistic regression, we examined demographic and clinical factors associated with prescription of NNRTIs despite documented NNRTI-R, and associated changes in plasma HIV RNA viral load and CD4 cell counts. Sixteen of 133 (12%) participants with documented NNRTI-R re-started NNRTIs for a median of 370 days (IQR 105–919) with a median 402 days (IQR 70–841) between documentation of NNRTI-R to NNRTI recycling. Participants recycling NNRTIs were less likely to have documented past non-adherence (40.0% vs. 69.2%; p=0.02). Among twelve patients with virologic data at 24 (±8) weeks; seven (58.3%) experienced virologic suppression while on the recycled NNRTI-based regimens. Of the five who failed to suppress, three with subsequent genotyping developed additional NNRTI-R mutations compromising higher generation NNRTIs. While NNRTI's were recycled in only a small fraction of LEGACY participants harboring NNRTI-R mutations, such recycling increased the risk of inducing further resistance mutations that compromised use of higher generation NNRTIs.

    Background Kenya experienced a political and humanitarian crisis following presidential elections on 27 December 2007. Over 1,200 people were killed and 300,000 displaced, with disproportionate violence in western Kenya. We sought to describe the immediate impact of this conflict on return to clinic and medication adherence for HIV-infected children cared for within the USAID-Academic Model Providing Access to Healthcare (AMPATH) in western Kenya. Methods We conducted a mixed methods analysis that included a retrospective cohort analysis, as well as key informant interviews with pediatric healthcare providers. Eligible patients were HIV-infected children, less than 14 years of age, seen in the AMPATH HIV clinic system between 26 October 2007 and 25 December 2007. We extracted demographic and clinical data, generating descriptive statistics for pre- and post-conflict antiretroviral therapy (ART) adherence and post-election return to clinic for this cohort. ART adherence was derived from caregiver-report of taking all ART doses in past 7 days. We used multivariable logistic regression to assess factors associated with not returning to clinic. Interview dialogue from was analyzed using constant comparison, progressive coding and triangulation. Results Between 26 October 2007 and 25 December 2007, 2,585 HIV-infected children (including 1,642 on ART) were seen. During 26 December 2007 to 15 April 2008, 93% (N = 2,398) returned to care. At their first visit after the election, 95% of children on ART (N = 1,408) reported perfect ART adherence, a significant drop from 98% pre-election (p < 0.001). Children on ART were significantly more likely to return to clinic than those not on ART. Members of tribes targeted by violence and members of minority tribes were less likely to return. In qualitative analysis of 9 key informant interviews, prominent barriers to return to clinic and adherence included concerns for personal safety, shortages of resources, hanging priorities, and

    Background Gut damage resulting in microbial translocation (MT) is considered a major cause of immune activation (IA) in HIV infection, but data in children are limited, particularly in the absence of antiretroviral therapy. Methods Sixty perinatally HIV-infected, antiretroviral therapy–naive children, aged 2–12 years, were evaluated for plasma levels of lipopolysaccharide, DNA sequences encoding bacterial ribosomal 16 second (16S) RNA (16S rDNA) and soluble CD14 concurrently with markers of CD4 and CD8 T-cell IA and immune exhaustion (IE), CD4 counts, and plasma viral load. At study entry, participants were classified into immune categories (ICs): IC1 (CD4% > 25), IC2 (CD4% 15–25), and IC3 (CD4% < 15). Age-matched HIV-uninfected children served as controls. Data were evaluated at study entry and at 12 months. Results Levels of MT, IA, and IE were increased in patients as compared with controls, were highest in patients in IC3 group, and did not change over 12 months. MT products lipopolysaccharide and 16S rDNA correlated with each other and each correlated with plasma viral load, soluble CD14, and T-cell IA and IE. There was a correlation of IA with IE. CD4 counts and percentage were inversely correlated with MT products and underlying CD4 activation. Conclusions In a natural history cohort of HIV-infected children not on therapy, MT was more pronounced in the most severely immunocompromised patients and was associated with IA. Strategies to reduce MT may help to reduce IA and prevent CD4 depletion. PMID:24378729

    Objective This study aims to engage children living with HIV/AIDS and their caregivers in a qualitative assessment to address psychosocial needs pertaining to this population. The purpose is to identify unique situations and concerns they experienced in dealing with the disease and ongoing treatment process. Material and Method Individual in-depth interviews using a semi-structured interview guide were employed. Results Thirty-four children (12 boys and 22 girls) aged 8–16 and thirty-five primary caretakers (6 males and 29 females) aged 21–66 participated in this study. Results identified some of the common concerns and challenges shared among this population, including impact of the illness on loved ones, disclosure, adherence, behavioural problems, discrimination, treatment affordability, and financial constraints. Certain issues that emerged as important themes specific to this population include unwarranted concerns about certain aspects of the illness, misinterpretation of the nonverbal clues within families, future child guardianship and placement planning, treatment availability during transitional period, and the challenge of maintaining the confidentiality of the diagnosis. Conclusion The needs and suggestions of the target groups provided the framework for improving the current services such as the provision of private sessions with children separated from their caregivers (especially for older children and adolescents), disclosure intervention, behavioral screening, life skills building, and empowerment mobilization. Thus, the information gained can be used to facilitate the holistic and humanized health care provision for children living with HIV/AIDS. PMID:19253500

    The non-nucleoside reverse transcriptase inhibitor efavirenz is part of the WHO guidelines for preferred first-line treatment of HIV-1-infected adults, pregnant and lactating women, and children. Efavirenz is well known to cause CNS toxicity. Although good data for CNS toxicity are available for adults, the opposite is true for children. Paediatric studies on this topic frequently suffer from small sample sizes or absence of thorough neuropsychiatric assessments. In this Personal View, we focus on two knowledge gaps of CNS toxicity of efavirenz in children. First, plasma concentrations of efavirenz are difficult to predict in children because of immaturity of and genetic variation in metabolic enzymes. Second, efavirenz exerts a lysergide (LSD)-like effect on brain serotonergic pathways and affects CNS metabolic pathways, including mitochondrial function. Whether these effects interfere with normal brain development is unknown. These uncertainties underline the imminent need for better monitoring of mental health and neurocognitive development in children given and exposed to efavirenz. PMID:27599655

    A real-time wireless electronic adherence monitor (EAM) and weekly self-report of missed doses via interactive voice response (IVR) and short message service (SMS) queries were used to measure antiretroviral therapy adherence in 49 adults and 46 children in rural Uganda. Median adherence was 89.5% among adults and 92.8% among children by EAM, and 99-100% for both adults and children by IVR/SMS self-report. Loss of viral suppression was significantly associated with adherence by EAM (odds ratio 0.58 for each 10% increase), but not IVR/SMS. Wireless EAM creates an exciting opportunity to monitor and potentially intervene with adherence challenges as they are happening. PMID:23751260

    Background If children born to HIV-infected mothers are not identified early, approximately 30% of them will die within the first year of life due to opportunistic infections. In order to prevent morbidity and mortality due to opportunistic infections in children, the World Health Organization recommends the use of prophylaxis using co-trimoxazole. However, the challenges affecting effective implementation of this policy in Tanzania have not been documented. Aim In this study, we assessed the challenges facing the provision of co-trimoxazole prophylaxis among children born to HIV-infected mothers in the public hospitals of Dar es Salaam, Tanzania. Methodology Four hundred and ninety-eight infants’ PMTCT (Prevention of Mother-to-Child Transmission of HIV) register books for the past 2 years were reviewed to obtain information regarding the provision of co-trimoxazole prophylaxis. One hundred and twenty-six health care workers were interviewed to identify success stories and challenges in the provision of co-trimoxazole prophylaxis in children. In addition, 321 parents and guardians of children born to HIV-infected mothers were interviewed in the health facilities. Results Approximately 80% of children were initiated with co-trimoxazole prophylaxis within 2 months after birth. Two hundred and ninety-one (58.4%) children started using co-trimoxazole within 4 weeks after birth. Majority (n=458, 91.8%) of the children were prescribed 120 mg of co-trimoxazole per day, whereas 39 (7.8%) received 240 mg per day. Only a small proportion (n=1, 0.2%) of children received 480 mg/day. Dose determination was based on the child’s age rather than body weight. Parents and guardians reported that 42 (13.1%) children had missed one or more doses of co-trimoxazole during the course of prophylaxis. The majority of health care workers (89.7%) reported that co-trimoxazole is very effective for the prevention of opportunistic infections among children, but frequent shortage of co

    This cross-sectional, facility-based study aimed to determine the prevalence, age, and main agent of disclosure among Nigerian children on antiretroviral therapy. It also sought to elicit barriers to, and facilitators of disclosure; and any association between disclosure and health outcomes. A semi-structured questionnaire was administered to 110 parents/caregivers of children ≥6 years. CD4 count, viral load, opportunistic infections and adherence information were also extracted from medical records for all 110 children. The mean age of the children in the study was 10.15 years (SD = 2.97), with a median (range) of 9.50 (6-18) years. According to parents/caregivers' accounts, 34 (30.9%) children knew that they were living with HIV, while 74 (67.3%) did not know. Mean age at disclosure was 10.47 years (SD = 2.62), with a median (range) of 10.00 (6-17) years. Most children (79.4%) were disclosed at home by their parent(s)/caregiver. The rest were disclosed at the hospital: five were disclosed by a healthcare provider, while two were accidentally disclosed. The most common reasons for disclosure were related to adherence issues - either to help prepare the children to take their medicines or that the child had refused to take his/her medicines (39.4%). This was followed by the child asking a lot of questions related to his/her health, frequent visits to the hospital, or why s/he was taking a lot of medicines even though s/he did not feel ill (27.3%). Most parents/caregivers did not disclose because the child was considered too young (84.0%) or will not be able to keep their HIV status a secret (10.7%). Multivariate logistic regression showed that only child's age was a statistically significant predictor of status disclosure (OR 1.69, p = .002; 95% CI 1.21-2.34). There was no association between disclosure and self-reported adherence (p = .615). PMID:26883299

    Introduction In Nigeria, there is a dearth of pediatric data on the risk factors associated with tuberculosis (TB), before and after antiretroviral therapy (ART). Methodology A retrospective observational cohort study, between October 2010 and December 2013, at the Federal Medical Centre, Makurdi, Nigeria. TB was noted among children less than 15 years of age at ART enrolment (prevalent TB-PrevTB), within 6 months (early incident tuberculosis-EITB) and after 6 months (late incident tuberculosis-LITB) of a 12-month follow-up on ART. Potential risk factors for PrevTB and incident TB were assessed using the multivariate logistic and Cox regression models respectively. Results Among 368 HIV-1 infected children, PrevTB was diagnosed in 73 children (19.8%). Twenty-eight EITB cases were diagnosed among 278 children over 132 person-years (py) with an EITB rate of 21.2/100 py. Twelve LITB cases were seen among 224 children over 221.9 py with a LITB rate of 5.4/100 py. A significant reduction in the incidence rates of TB was found over time (75%, p˂ 0.001). Young age of children (12–35 months, aOR; 24, 95% CI; 4.1–146.6, p ˂ 0.001; 36–59 months, aOR;21, 95%CI;4.0–114.3, p ˂ 0.001); history of TB in children (aOR; 29, 95% CI; 7.3–119.4, P˂ 0.001); severe immunosuppression (aOR;38, 95% CI;12–123.2,p ˂ 0.001); oropharyngeal candidiasis (aOR;3.3, 95% CI; 1.4–8.0, p = 0.009) and sepsis (aOR; 3.2, 95% CI;1.0–9.6, p = 0.043) increased the risk of PrevTB. Urban residency was protective against EITB (aHR; 0.1, 95% CI; 0.0–0.4, p = 0.001). Virological failure (aHR; 4.7, 95% CI; 1.3–16.5, p ˂ 0.001) and sepsis (aHR; 26, 95% CI; 5.3–131.9, p ˂ 0.001) increased the risk of LITB. Conclusions In our cohort of HIV-infected children, a significant reduction in cases of incident TB was seen following a 12-month use of ART. After ART initiation, TB screening should be optimized among children of rural residency, children with sepsis, and those with poor virological

    Background HIV-infected infants have high risk of death in the first two years of life if untreated. WHO guidelines recommend early infant HIV diagnosis (EID) of all HIV-exposed infants and immediate antiretroviral therapy (ART) in HIV-infected children under 24-months. We assessed the cost-effectiveness of this strategy in HIV-exposed non-breastfed children in Thailand. Methods A decision analytic model of HIV diagnosis and disease progression compared: EID using DNA PCR with immediate ART (Early-Early); or EID with deferred ART based on immune/clinical criteria (Early-Late); vs. clinical/serology based diagnosis and deferred ART (Reference). The model was populated with survival and cost data from a Thai observational cohort and the literature. Incremental cost-effectiveness ratio per life-year gained (LYG) was compared against the Reference strategy. Costs and outcomes were discounted at 3%. Results Mean discounted life expectancy of HIV-infected children increased from 13.3 years in the Reference strategy to 14.3 in the Early-Late and 17.8 years in Early-Early strategies. The mean discounted lifetime cost was $17,335, $22,583 and $29,108, respectively. The cost-effectiveness ratio of Early-Late and Early-Early strategies was $5,149 and $2,615 per LYG, respectively as compared to the Reference strategy. The Early-Early strategy was most cost-effective at approximately half the domestic product per capita per LYG ($4,420 in Thailand 2011). The results were robust in deterministic and probabilistic sensitivity analyses including varying perinatal transmission rates. Conclusion In Thailand, EID and immediate ART would lead to major survival benefits and is cost- effective. These findings strongly support the adoption of WHO recommendations as routine care.

    Background We previously reported no benefit of early weaning for HIV-free survival of children born to HIV-infected mothers in intent-to-treat analyses. Since early weaning was poorly accepted, we conducted a secondary analysis to investigate whether beneficial effects may have been hidden. Methods 958 HIV-infected women in Lusaka, Zambia, were randomized to abrupt weaning at 4 months (intervention) or to continued breastfeeding (control). Children were followed to 24 months with regular HIV PCR tests and examinations to determine HIV infection or death. Detailed behavioral data were collected on when all breastfeeding ended. Most participants were recruited before antiretroviral treatment (ART) became available. We compared outcomes among mother-child pairs who weaned earlier or later than intended by study design adjusting for potential confounders. Results Of infants alive, uninfected and still breastfeeding at 4 months in the intervention group, 16.1% who weaned as instructed acquired HIV or died by 24 months compared to 16.0% who did not comply (p = 0.98). Children of women with less severe disease during pregnancy (not eligible for ART) had worse outcomes if their mothers weaned as instructed (RH = 2.60 95% CI: 1.06–6.36) compared to those who continued breastfeeding. Conversely, children of mothers with more severe disease (eligible for ART but did not receive it) who weaned early had better outcomes (p-value interaction = 0.002). In the control group, weaning before 15 months was associated with 3.94-fold (95% CI: 1.65–9.39) increase in HIV infection or death among infants of mothers with less severe disease. Conclusion Incomplete adherence did not mask a benefit of early weaning. On the contrary, for women with less severe disease, early weaning was harmful and continued breastfeeding resulted in better outcomes. For women with more advanced disease, ART should be given during pregnancy for maternal health and to reduce transmission

    HIV and violence are two major public health problems increasingly shown to be connected and relevant to international mental health issues and HIV-related services. Qualitative research is important due to the dearth of literature on this association in developing countries, cultural influences on mental health syndromes and presentations, and the sensitive nature of the topic. The study presented in this paper sought to investigate the mental health issues of an HIV-affected population of women and children in Lusaka, Zambia, through a systematic qualitative study. Two qualitative methods resulted in the identification of three major problems for women: domestic violence (DV), depression-like syndrome, and alcohol abuse; and children: defilement, DV, and behavior problems. DV and sexual abuse were found to be closely linked to HIV and alcohol abuse. This study shows the local perspective of the overlap between violence and HIV. Results are discussed in relation to the need for violence and abuse to be addressed as HIV services are implemented in sub-Saharan Africa. PMID:16909070

    Background. The optimal treatment of malaria in human immunodeficiency virus (HIV)–infected children requires consideration of critical drug–drug interactions in coinfected children, as these may significantly impact drug exposure and clinical outcomes. Methods. We conducted an intensive and sparse pharmacokinetic/pharmacodynamic study in Uganda of the most widely adopted artemisinin-based combination therapy, artemether-lumefantrine. HIV-infected children on 3 different first-line antiretroviral therapy (ART) regimens were compared to HIV-uninfected children not on ART, all of whom required treatment for Plasmodium falciparum malaria. Pharmacokinetic sampling for artemether, dihydroartemisinin, and lumefantrine exposure was conducted through day 21, and associations between drug exposure and outcomes through day 42 were investigated. Results. One hundred forty-five and 225 children were included in the intensive and sparse pharmacokinetic analyses, respectively. Compared with no ART, efavirenz (EFV) reduced exposure to all antimalarial components by 2.1- to 3.4-fold; lopinavir/ritonavir (LPV/r) increased lumefantrine exposure by 2.1-fold; and nevirapine reduced artemether exposure only. Day 7 concentrations of lumefantrine were 10-fold lower in children on EFV vs LPV/r-based ART, changes that were associated with an approximate 4-fold higher odds of recurrent malaria by day 28 in those on EFV vs LPV/r-based ART. Conclusions. The choice of ART in children living in a malaria-endemic region has highly significant impacts on the pharmacokinetics and pharmacodynamics of artemether-lumefantrine treatment. EFV-based ART reduces all antimalarial components and is associated with the highest risk of recurrent malaria following treatment. For those on EFV, close clinical follow-up for recurrent malaria following artemether-lumefantrine treatment, along with the study of modified dosing regimens that provide higher exposure, is warranted.

    Approximately 700,000 children become newly infected with HIV annually, mainly through mother-to-child transmission (MTCT), making paediatric HIV a leading cause of morbidity and mortality worldwide. The substantial interest in preventing MTCT (PMTCT) has generated information on rates of transmission and associated factors, but there is a lack of information on disease progression and mortality in vertically-infected children, especially from resource-poor settings. Peer-review journals with titles or abstracts containing reference to the review's themes were selected using widely available search engines. We review relevant literature on mortality in children born to HIV infected mothers; morbidity and mortality associated with paediatric HIV infections; eligibility to and efficacy of antiretroviral therapy (ART). Child mortality is independently associated with maternal HIV status and maternal death, with paediatric infection resulting in approximately 4 fold increase in mortality by age 2 years. Morbidities seen in infected children were similar to those seen in uninfected children, although the rates and recurrences of illness were greater. There is some evidence that progression to AIDS may be more rapid in resource poor settings, although data on this are very limited. PMTCT and paediatric ART have been shown to be highly successful in resource-limited settings, but are not universally applied. Further efforts to increase coverage of both PMTCT and paediatric ART could substantially reduce the numbers of children becoming infected and improve survival of those infected. Additionally, improvements in health infrastructures could improve care provision, not only through improved detection and monitoring but also through treatment of co-morbidities and nutritional support.

    Abstract Objective To assess 12-month survival, pharmacokinetics, immunologic and virologic efficacy, tolerance, compliance and drug resistance in HIV-infected children in Bobo-Dioulasso, Burkina Faso, receiving once-daily highly-active antiretroviral therapy as a combination of didanosine (DDI), lamivudine (3TC) and efavirenz (EFV). Methods In the ANRS 12103 open phase II trial, HIV-infected children were examined at inclusion and monthly thereafter. CD4+ T-lymphocyte (CD4) count, plasma concentration of ribonucleic acid (RNA) of human immunodeficiency virus type 1 (HIV-1) and haematologic and biochemical parameters were measured at baseline and every trimester. HIV-1 resistance testing was performed in case of viral escape. Drug plasma concentrations were determined with high-performance liquid chromatography. Findings From February 2006 to November 2007, 51 children (39% girls) with a mean age of 6.8 years were enrolled and treated for 12 months. At baseline, Z scores for mean weight-for-age and mean height-for-age were −2.01 and −2.12, respectively. Mean CD4% was 9.0. Median plasma HIV-1 RNA viral load was 5.51 log10 copies per millilitre (cp/ml). Two children (3.9%) died and another 11 (22%) suffered 13 severe clinical events. At month 12, mean WAZ had improved by 0.63 (P < 0.001) and mean HAZ by 0.57 (P < 0.001). Mean CD4% had risen to 24 (P < 0.001). Viral load was below 300 RNA cp/ml in 81% of the children; HIV resistance mutations were detected in 11 (21.6%). Conclusion The once-a-day combination of DDI + 3TC + EFV is an alternative first-line treatment for HIV-1-infected children. Dose adjustment should further improve efficacy. PMID:21673861

    Introduction Approximately 2.5 million children below 15 years are infected with the HIV virus, with 90% in sub-Saharan Africa. The Yaounde Gynaeco-obstetric and Pediatric hospital has been a treatment center for HIV since 2006. The aim of this study was to analyze the baseline demographic, clinical and immunologic characteristics of the children with the HIV infection in this hospital. Methods It was a retrospective, cross- sectional and analytic study, carried out between January and April 2011 which included 61 HIV positive children aged 0-15 years. The socio-demographic, clinical and immunologic data were obtained from their medical records. Results Most (52.5%) of the children studied were above 60 months of age with a mean age of 71 months. Most (57.4%) were females. Mother-to-child transmission was the principal mode of contamination in 88.5% of cases. More than half of their mothers (55.7%) did not receive antiretroviral prophylaxis during pregnancy and labor. Common clinical findings included prolonged fever (44.6%), malnutrition (37.6%), lymphadenopathy (34.4%), respiratory tract infections (34.4%) and diarrhea (24.5%). Diagnosis was confirmed by HIV serology for most of the patients (93.4%). Polymerase chain reaction served as method of diagnosis in only 6.6% of the cases. HIV 1 was the predominant viral type. More than half of the children (52.5%) were seen at an advanced stage of the disease. Conclusion HIV screening during pregnancy and prevention of mother-to-child transmission should be reinforced in this context, and fathers of HIV-infected children should be encouraged to go for HIV testing.

    Mucosal-associated invariant T cells (MAIT) are innate T cells restricted by major histocompatibility related molecule 1 (MR1) presenting riboflavin metabolite ligands derived from microbes. Specificity to riboflavin metabolites confers MAIT cells a broad array of host-protective activity against gram-negative and -positive bacteria, mycobacteria, and fungal pathogens. MAIT cells are present at low levels in the peripheral blood of neonates and gradually expand to relatively abundant levels during childhood. Despite no anti-viral activity, MAIT cells are depleted early and irreversibly in HIV infected adults. Such loss or impaired expansion of MAIT cells in HIV-positive children may render them more susceptible to common childhood illnesses and opportunistic infections. In this study we evaluated the frequency of MAIT cells in perinatally HIV-infected children, their response to antiretroviral treatment and their associations with HIV clinical status and related innate and adaptive immune cell subsets with potent antibacterial effector functions. We found HIV+ children between ages 3 to 18 years have significantly decreased CD8+ MAIT cell frequencies compared to uninfected healthy children. Remarkably, CD8 MAIT levels gradually increased with antiretroviral therapy, with greater recovery when treatment is initiated at a young age. Moreover, diminished CD8+ MAIT cell frequencies are associated with low CD4:CD8 ratios and elevated sCD14, suggesting a link with HIV disease progression. Last, CD8+ MAIT cell levels tightly correlate with other antibacterial and mucosa-protective immune subsets, namely, neutrophils, innate-like T cells, and Th17 and Th22 cells. Together these findings suggest that low frequencies of MAIT cells in HIV positive children are part of a concerted disruption to the innate and adaptive immune compartments specialized in sensing and responding to pathogenic or commensal bacteria.

    Background Atazanavir is an attractive option for the treatment of Pediatric HIV infection, based on once daily dosing and the availability of a formulation appropriate for younger children. PACTG 1020A was a phase I/II open label study of atazanavir (ATV) (with/without ritonavir [RTV] boosting)-based treatment of HIV-infected children; here we report the long-term safety and virologic and immunologic responses. Methods Antiretroviral-naïve and experienced children, ages 91 days to 21 years, with baseline plasma HIV RNA >5000 copies/ml (cpm) were enrolled at sites in the United States and South Africa. Results Of 195 children enrolled 142 (73%) subjects received ATV-based regimens at the final protocol recommended dose. 58% were treatment naive. Overall, at week 24, 84/139 subjects (60.4%) and at week 48, 83/142 (58.5%), had HIV RNA ≤400 cpm. At week 48, 69.5% of naïve and 43.3% of experienced subjects had HIV RNA ≤400 cpm; median CD4 increase was 196.5 cells/mm3. The primary adverse event was increased serum bilirubin; 9% of subjects had levels > 5.1 times upper limit of normal and 1.4% noted jaundice. 3% of subjects experienced Grade 2 or 3 prolongation in PR or QTc intervals. At week 48, there was a 15% increase in total cholesterol (TC), with TC >199 mg/dL increasing from 1% at baseline to 5.7%. Conclusions Use of once-daily ATV, with/without RTV, was safe and well tolerated in children, with acceptable levels of viral suppression and CD4 count increase. The primary adverse event, as expected, was an increase in bilirubin levels. PMID:25232777

    Current UNAIDS goals aimed to end the AIDS epidemic set out to ensure that 90% of all people living with HIV know their status, 90% initiate and continue life-long anti-retroviral therapy (ART), and 90% achieve viral load suppression. In 2014 there were an estimated 2.6 million children under 15 years of age living with HIV, of which only one-third were receiving ART. Little literature exists describing retention of HIV-infected children in the first year on ART. We conducted a systematic search for English language publications reporting on retention of children with median age at ART initiation less than ten years in resource limited settings. The proportion of children retained in care on ART and predictors of attrition were identified. Twelve studies documented retention at one year ranging from 71–95% amongst 31877 African children. Among the 5558 children not retained, 4082 (73%) were reported as lost to follow up (LFU) and 1476 (27%) were confirmed to have died. No studies confirmed the outcomes of children LFU. Predictors of attrition included younger age, shorter duration of time on ART, and severe immunosuppression. In conclusion, significant attrition occurs in children in the first 12 months after ART initiation, the majority attributed to LFU, although true outcomes of children labeled as LFU are unknown. Focused efforts to ensure retention and minimize early mortality are needed as universal ART for children is scaled up. PMID:27280404

  16. Phase II trial of standard versus increased transfusion volume in Ugandan children with acute severe anemia

    PubMed Central

    2014-01-01

    Background Severe anemia (SA, hemoglobin <6 g/dl) is a leading cause of pediatric hospital admission in Africa, with significant in-hospital mortality. The underlying etiology is often infectious, but specific pathogens are rarely identified. Guidelines developed to encourage rational blood use recommend a standard volume of whole blood (20 ml/kg) for transfusion, but this is commonly associated with a frequent need for repeat transfusion and poor outcome. Evidence is lacking on what hemoglobin threshold criteria for intervention and volume are associated with the optimal survival outcomes. Methods We evaluated the safety and efficacy of a higher volume of whole blood (30 ml/kg; Tx30: n = 78) against the standard volume (20 ml/kg; Tx20: n = 82) in Ugandan children (median age 36 months (interquartile range (IQR) 13 to 53)) for 24-hour anemia correction (hemoglobin >6 g/dl: primary outcome) and 28-day survival. Results Median admission hemoglobin was 4.2 g/dl (IQR 3.1 to 4.9). Initial volume received followed the randomization strategy in 155 (97%) patients. By 24-hours, 70 (90%) children in the Tx30 arm had corrected SA compared to 61 (74%) in the Tx20 arm; cause-specific hazard ratio = 1.54 (95% confidence interval 1.09 to 2.18, P = 0.01). From admission to day 28 there was a greater hemoglobin increase from enrollment in Tx30 (global P <0.0001). Serious adverse events included one non-fatal allergic reaction and one death in the Tx30 arm. There were six deaths in the Tx20 arm (P = 0.12); three deaths were adjudicated as possibly related to transfusion, but none secondary to volume overload. Conclusion A higher initial transfusion volume prescribed at hospital admission was safe and resulted in an accelerated hematological recovery in Ugandan children with SA. Future testing in a large, pragmatic clinical trial to establish the effect on short and longer-term survival is warranted. Trial registration ClinicalTrials.Gov identifier: NCT01461590

  17. Rural and urban Ugandan primary school children's alternative ideas about animals

    Otaala, Justine

    This study examined rural and urban Ugandan primary children's alternative ideas about animals through the use of qualitative research methods. Thirty-six children were selected from lower, middle, and upper primary grades in two primary schools (rural and urban). Data were collected using interview-about-instance technique. Children were shown 18 color photographs of instances and non-instances of familiar animals and asked to say if the photographed objects were animals or not. They were then asked to give reasons to justify their answers. The interviews were audiotaped and transcribed. The results indicate that children tended to apply the label "animal" to large mammals, usually found at home, on the farm, in the zoo, and in the wild. Humans were not categorized as animals, particularly by children in the lower grades. Although the children in upper grades correctly identified humans as animals, they used reasons that were irrelevant to animal attributes and improperly derived from the biological concept of evolution. Many attributes children used to categorize instances of animals were scientifically unacceptable and included superficial features, such as body outline, anatomical features (body parts), external features (visual cues), presence or absence and number of appendages. Movement and eating (nutrition) were the most popular attributes children used to identify instances of animals. The main differences in children's ideas emanated from the reasons used to identify animals. Older rural children drew upon their cultural and traditional practices more often than urban children. Anthropomorphic thinking was predominant among younger children in both settings, but diminished with progression in children's grade levels. Some of the implications of this study are: (1) teachers, teacher educators and curriculum developers should consider learners' ideas in planning and developing teaching materials and interventions. (2) Teachers should relate humans to other

    Background The capacity of pneumococcal vaccination to confer memory in HIV-infected children is critical for durable protection. Methods HIV-infected children 2–<19 years administered two doses of pneumococcal conjugate vaccine (PCV7) and one dose of polysaccharide vaccine (PPV) on HAART were randomized four-five years later to receive a PCV7 or PPV booster. Total and high avidity antibodies to serotypes 1 (PPV) and 6B and 14 (PCV7 and PPV) were determined by ELISA. Memory was defined as persistence of ≥0.5 mcg/mL of serotype-specific antibody on day 0 or change from <0.5 mcg/mL to ≥0.5 mcg/mL between day 0 and week 1, or, ≥4-fold antibody rise between day 0 and week 1. Results Prior to boosting, four to five years after the previous PCV7-PCV7-PPV series, geometric mean concentrations (GMCs) were 0.46 mcg/mL (serotype 1), 1.31 mcg/mL (serotype 6B), and 1.47 mcg/mL (serotype 14), with concentrations ≥0.5 mcg/mL in 41% (serotype 1) to 82% (serotypes 6B and 14). Memory based on antibody concentration ≥0.5 mcg/mL before or 1 week after boosting with PCV7 or PPV was demonstrated in 42–61% for serotype 1 and 87–94% for serotypes 6B and 14, with lower rates based on day 0 to week 1 ≥4-fold antibody rise (serotype 1, 3–13%; serotype 6B, 13–31%; serotype 14, 29–53%). Antibody concentrations post-boosting were greater following PCV7 than PPV for serotypes 6B and 14. Ratios of highly avid to total antibody pre- and post-boosting were 0.5–0.8. Predictors of memory included higher CD4% (nadir before HAART and at P1024 and P1061s entry), CD19% (at P1024 and P1061s entry), and antibody response after the PCV7-PCV7-PPV primary series and lower viral load (at P1024 and P1061s entry) and age. Conclusions Protective antibody concentrations, high avidity, and booster responses to PCV7 or PPV indicative of memory were present four-five years after PCV7-PCV7-PPV in HIV-infected children on HAART.

    Access to high-quality reproductive health care is important for adolescents and young adults with HIV infection to prevent unintended pregnancies, sexually transmitted infections, and secondary transmission of HIV to partners and children. As perinatally HIV-infected children mature into adolescence and adulthood and new HIV infections among adolescents and young adults continue to occur in the United States, medical providers taking care of such individuals often face issues related to sexual and reproductive health. Challenges including drug interactions between several hormonal methods and antiretroviral agents make decisions regarding contraceptive options more complex for these adolescents. Dual protection, defined as the use of an effective contraceptive along with condoms, should be central to ongoing discussions with HIV-infected young women and couples wishing to avoid pregnancy. Last, reproductive health discussions need to be integrated with discussions on HIV care, because a reduction in plasma HIV viral load below the level of detection (an "undetectable viral load") is essential for the individual's health as well as for a reduction in HIV transmission to partners and children.

    Vitamin D plays an increasingly recognized role in the innate and adaptive immune response to infection. Based on demonstrated roles in up-regulating innate immunity, decreasing inflammation, and reducing the severity of disease in illnesses such as tuberculosis and influenza, we hypothesized that poor vitamin D status would be associated with severe malaria. We measured 25-hydroxyvitamin D [25(OH)D] by immunoassay in a sample of Ugandan children aged 18 months-12 years with severe malaria (cerebral malaria or severe malarial anemia, n = 40) and in healthy community children (n = 20). Ninety-five percent of children with severe malaria (n = 38) and 80% of control children (n = 16) were vitamin D-insufficient [plasma 25(OH)D <30 ng/mL]. Mean plasma 25(OH)D levels were significantly lower in children with severe malaria than in community children (21.2 vs. 25.3 ng/mL, p = 0.03). Logistic regression revealed that for every 1 ng/mL increase in plasma 25(OH)D, the odds of having severe malaria declined by 9% [OR = 0.91 (95% CI: 0.84, 1.0)]. These preliminary results suggest that vitamin D insufficiency may play a role in the development of severe malaria. Further prospective studies in larger cohorts are indicated to confirm the relationship of vitamin D levels to severity of malaria infection and to investigate causality. PMID:25470777

    Background HIV-infected individuals mount poor antibody responses to vaccines. We sought to identify the immunologic and virologic factors associated with a robust response to hepatitis Avirus (HAV) vaccine in children on highly active antiretroviral treatment. Methods One hundred fifty-two pediatric highly active antiretroviral treatment recipients immunized against HAV at weeks 0 and 24 had anti-HAV antibodies, CD4+, CD8+, and CD19+ cell percent assessed at weeks 0 and 32. Subgroups had HIV viremia, B- and T-cell subpopulations, and cell-mediated immunity (CMI) to HAV and other stimulants measured. Results Anti-HAV antibodies after complete vaccination correlated positively with CD4+ percent and CD19+ percent and negatively with viremia and CD8+ percent at baseline, but not at 32 weeks. There were no significant correlations between anti-HAV antibodies and B- or T-cell-naïve, memory, or activated subpopulations or non-HAV CMI. Compared with children who remained HAV-CMI-negative, those who mounted HAV-CMI in response to vaccination had higher anti-HAV antibody titers and CD19+ CD21+ CD27+ memory B cell percent at 32 weeks, but no other differences. Conclusions In HIV-infected children on highly active antiretroviral treatment, control of viral replication and conserved or reconstituted CD19+ and CD4+ cell numbers and function determine a robust antibody response to anti-HAV primary immunization. Our data support a bidirectional B- and T-cell cooperation in the response to the HAV vaccine. PMID:19617848

    Summary Background WHO 2013 guidelines recommend universal treatment for HIV-infected children younger than 5 years. No paediatric trials have compared nucleoside reverse-transcriptase inhibitors (NRTIs) in first-line antiretroviral therapy (ART) in Africa, where most HIV-infected children live. We aimed to compare stavudine, zidovudine, or abacavir as dual or triple fixed-dose-combination paediatric tablets with lamivudine and nevirapine or efavirenz. Methods In this open-label, parallel-group, randomised trial (CHAPAS-3), we enrolled children from one centre in Zambia and three in Uganda who were previously untreated (ART naive) or on stavudine for more than 2 years with viral load less than 50 copies per mL (ART experienced). Computer-generated randomisation tables were incorporated securely within the database. The primary endpoint was grade 2–4 clinical or grade 3/4 laboratory adverse events. Analysis was intention to treat. This trial is registered with the ISRCTN Registry number, 69078957. Findings Between Nov 8, 2010, and Dec 28, 2011, 480 children were randomised: 156 to stavudine, 159 to zidovudine, and 165 to abacavir. After two were excluded due to randomisation error, 156 children were analysed in the stavudine group, 158 in the zidovudine group, and 164 in the abacavir group, and followed for median 2·3 years (5% lost to follow-up). 365 (76%) were ART naive (median age 2·6 years vs 6·2 years in ART experienced). 917 grade 2–4 clinical or grade 3/4 laboratory adverse events (835 clinical [634 grade 2]; 40 laboratory) occurred in 104 (67%) children on stavudine, 103 (65%) on zidovudine, and 105 (64%), on abacavir (p=0·63; zidovudine vs stavudine: hazard ratio [HR] 0·99 [95% CI 0·75–1·29]; abacavir vs stavudine: HR 0·88 [0·67–1·15]). At 48 weeks, 98 (85%), 81 (80%) and 95 (81%) ART-naive children in the stavudine, zidovudine, and abacavir groups, respectively, had viral load less than 400 copies per mL (p=0·58); most ART

    HIV primary infection occurs at mucosa tissues, suggesting an intricate interplay between microbiome and HIV infection. Recent advanced technologies of high-throughput sequencing and bioinformatics allow researchers to explore nonculturable microbes including bacteria, virus and fungi and their association with diseases. HIV/SIV infection is associated with microbiome shifts and immune activation that may affect the outcome of disease progression. Similarly, altered microbiome and inflammation are associated with increased risks of HIV acquisition, suggesting the role of microbiome in HIV transmission. In this review, we will focus on microbiome in HIV infection at various mucosal compartments. Understanding the relationship between microbiome and HIV may offer insights into development of better strategies for HIV prevention and treatment. PMID:25439273

    Background Prevention of mother-to-child transmission has been considered as not a simple intervention but a comprehensive set of interventions requiring capable health workers. Viet Nam's extensive health care system reaches the village level, but still HIV-infected mothers and children have received inadequate health care services for prevention of mother-to-child transmission. We report here the health workers' perceptions on factors that lead to their failure to give good quality prevention of mother-to-child transmission services. Methods Semistructured interviews with 53 health workers and unstructured observations in nine health facilities in Hanoi were conducted. Selection of respondents was based on their function, position and experience in the development or implementation of prevention of mother-to-child transmission policies/programmes. Results Factors that lead to health workers' failure to give good quality services for prevention of mother-to-child transmission include their own fear of HIV infection; lack of knowledge on HIV and counselling skills; or high workloads and lack of staff; unavailability of HIV testing at commune level; shortage of antiretroviral drugs; and lack of operational guidelines. A negative attitude during counselling and provision of care, treating in a separate area and avoidance of providing service at all were seen by health workers as the result of fear of being infected, as well as distrust towards almost all HIV-infected patients because of the prevailing association with antisocial behaviours. Additionally, the fragmentation of the health care system into specialized vertical pillars, including a vertical programme for HIV/AIDS, is a major obstacle to providing a continuum of care. Conclusion Many hospital staff were not being able to provide good care or were even unwilling to provide appropriate care for HIV-positive pregnant women The study suggests that the quality of prevention of mother-to-child transmission

    This thesis is based on seven previously published articles. The work was performed during my employment at The Department of Infectious Diseases, Copenhagen University Hospital, Hvidovre, as a scholarship student from 2000-2001 and as a research assistant in the period 2004-2010. HIV-infection is characterized by CD4+ cell depletion. The differences between patients in the degree of CD4+ cell recovery upon treatment with highly active antiretroviral therapy (HAART) may in part be due to differences in the supply of naïve CD4+ cells from the thymus. The thymus atrophies with increasing age for which reason the adult thymus was previously assumed to be without function. The aim of these investigations was to examine the role of the thymus in different aspects of HIV-infection: In adult HIV-infected patients, during HIV-positive pregnancy, and in HIV-exposed uninfected (HIV-EU) children born to HIV-infected mothers. Thymic size and output were determined in 25 adult HIV-infected patients receiving HAART and in 10 controls. Larger thymic size was associated with higher CD4 counts and higher thymic output. Furthermore, patients with abundant thymic tissue seemed to have broader immunological repertoires, compared with patients with minimal thymic tissue. The study supports the mounting evidence of a contribution by the adult thymus to immune reconstitution in HIV-infection. In a follow-up study conducted till 5 years of HAART, the importance of the thymus to the rate of cellular restoration was found to primarily lie within the first two years of HAART. The effect of recombinant human growth hormone (rhGH) was then investigated in a randomized, double-blinded placebo controlled trial in 46 adult HIV-infected patients on HAART. Daily treatment with a low dose of rhGH of 0.7mg for 40 weeks stimulated thymopoiesis as expressed by thymic size, density, and output strongly supporting the assumption that rhGH possesses the potential to stimulate the ageing thymus, holding

    Collaborative studies to determine the consequences of pregnancy in HIV infected women have been begun in the last 2 years. Both HIV and HIV antibodies pass through the placenta, and 30-50% of infants born to HIV infected mothers are infected in utero. In developed countries it is feasible to screen pregnant women in high risk groups for HIV positivity. In developing countries, where heterosexual transmission is the main route of infection, there are no high risk groups, and it is not feasible to screen all pregnant women. Some data have shown that HIV infection in pregnancy is associated with intrauterine growth retardation, low birth weight, and high infant mortality. There is no evidence that cesarean section reduces infection in neonates, and it should not be performed on HIV infected women. By 1987 almost 1.5% of AIDS cases in the US were in vertically infected infants. In Africa also the main factor in HIV in infancy is vertical transmission. AIDS in infancy follows 1 of 2 distinct patterns: failure to thrive and death from Pneumocystis carinii pneumonia within the 1st year or else apparent health during infancy but death from opportunistic infections by age 3. HIV infection in childhood is uncommon and can usually be traced to blood transfusions or unsterilized needles used for vaccinations. Neurological symptoms often develop early in children. Breast feeding probably does not infect any infants who have not already been infected in utero, and in developing counties breast feeding is still the best assurance of total nutrition. Pooled, unpasteurized milk banks, on the other hand, represent an unnecessary danger, and milk donors should be screened. Since there is no evidence that routine immunization accelerates the course of HIV infection, and since mass screening is not feasible in developing countries, the World Health Organization recommends that routine immunizations be continued. Since the best protection from in utero HIV infection is the use of

    Summary HIV (human immunodeficiency virus) infection may produce no clinical symptoms for 10 years on average. However, after many years of infection most people develop symptoms that indicate progression of the disease. There are no regular characteristic symptoms or early stage, and no logical sequence of AIDS indicator disorders has been observed. People who are not aware of the infection are referred to physicians of various specializations, including otolaryngologists. It is on their knowledge about HIV infections, among other factors, that early diagnosis of the disease depends. Appropriate and quick introduction of anti-retroviral drugs may let a person with HIV live decades longer. PMID:22367140

    Killing of CD4 lymphocytes and systemic immune suppression are the hallmarks of HIV infection. These milestones are produced by different mechanisms that draw a complex picture of AIDS immunopathogenesis. The role of the GALT system as a preferential target for HIV, chronic activation of the immune system and viral escape mechanisms are recent challenges that have changed our current view on the mechanisms leading to immune destruction and development of AIDS. In this article, the mechanisms of immune suppression, the evolution of immune response throughout the infection and the mechanisms of viral escape are analysed. PMID:21388715

    Objectives. To characterize the immunogenicity of a quadrivalent human papillomavirus vaccine (QHPV) in human immunodeficiency virus (HIV)–infected children, we studied their immune responses to 3 or 4 doses. Methods. HIV-infected children aged 7–12 years with a CD4 cell percentage of ≥15% of lymphocytes, received 3 doses of QHPV with or without a fourth dose after 72 weeks. Type-specific and cross-reactive antibodies and cell-mediated immunity were measured. Results. Type-specific antibodies to HPV6, 11, and 16 were detected in 100% and ≥94% of children at 4 and 72 weeks, respectively, after the third QHPV dose. Corresponding numbers for HPV18 were 97% and 76%, respectively. A fourth QHPV dose increased seropositivity to ≥96% for all vaccine genotypes. Four weeks after the third QHPV dose, 67% of vaccinees seroconverted to HPV31, an HPV16-related genotype not in the vaccine; 69% and 39% of vaccinees developed mucosal HPV16 and 18 immunoglobulin G antibodies, respectively; and 60% and 52% of vaccinees developed cytotoxic T lymphocytes (CTLs) for HPV16 and 31, respectively. Conclusions. Three QHPV doses generated robust and persistent antibodies to HPV6, 11, and 16 but comparatively weaker responses to HPV18. A fourth dose increased antibodies against all vaccine genotypes in an anamnestic fashion. CTLs and mucosal antibodies against vaccine genotypes, as well as cross-reactive antibodies and CTL against nonvaccine genotypes, were detected. PMID:22859825

    Pneumocystosis is an opportunistic disease caused by invasion of unicellular fungus Pneumocystic jirovecii which is responsible for febrile pneumonia among patients with cellular immunodeficiency especially those HIV infected. Despite the decreasing of its incidence due to the introduction of antiretroviral therapy, as well as anti-Pneumocystis prophylaxis among these patients, Pneumocystis pneumonia remains the first AIDS-defining event and a leading cause of mortality among HIV-infected patients. The usual radiological presentation is that of diffuse interstitial pneumonia. The diagnosis is confirmed by the detection of trophozoides and/or cysts P. jirovecii in bronchoalveolar lavage (BAL) samples using several staining techniques. The use of polymerase chain reaction in the BAL samples in conjunction with standard immunofluorescent or colorimetric tests have allowed for more has allowed for more rapid and accurate diagnosis. The standard regimen of treatment is the association of trimethoprim-sulfamethoxazole which has been utilized as an effective treatment with a favourable recovery. Early HIV diagnosis and antiretroviral therapy should reduce the incidence of this dreaded disease. PMID:27349824

    The incidence of lymphoma in patients with HIV infection greatly exceeds that of the general population. The increased risk for lymphoma appears related to multiple factors, including the transforming properties of the retrovirus itself, the immunosuppression and cytokine dysregulation that results from the disease, and, most importantly, opportunistic infections with other lymphotrophic herpes viruses such as Epstein–Barr virus and human herpesvirus 8. Histologically lymphomas fall into three groups: (1) those also occurring in immunocompetent patients; (2) those occurring more specifically in HIV‐positive patients; and (3) those also occurring in patients with other forms of immunosuppression. Aggressive lymphomas account for the vast majority cases. They frequently present with advanced stage, bulky disease with high tumour burden and, typically, involve extranodal sites. Clinical outcome appears to be worse than in similar aggressive lymphomas in the general population. However, following the introduction of highly active antiretroviral therapy, the risk for developing lymphoma in the context of HIV infection has decreased and the clinical outcome has improved.

    The two neighboring southwestern states of India, Karnataka and Maharashtra, have high incidence of HIV/AIDS and are among the six most high prevalence HIV infected states. In Karnataka state, the northern districts of Bagalkot, Belgaum and Bijapur (the three Bs) and in Maharashtra state, the southern districts of Sangli, Satara, and Solapur (the three Ss) are the areas with the highest incidence of HIV/AIDS. We have evaluated the incidence of maternal to child transmission (MTCT) of HIV-1 infection in Belgaum District which is more than 500 kilometers distance by road from the campus in greater Bangalore (Karnataka State). We have obtained the prenatal CD4 counts of HIV infected pregnant mothers. We have also screened the HIV infected children in two orphanages (rehabilitation centres for HIV infected children) in Belgaum District. The clinical conditions of these infected children were assessed for their CD4 counts, anti-retroviral therapy (ART) intake status, outpatient illnesses and body composition. We have observed that there is an influence of the age factor on the CD4 counts of the HIV infected children. Further, in view of the role of our recently found involvement of sulfatide, 3-O- galactosylceramide, in inhibition of HIV-1 replication and enhancement of hematopoiesis which is otherwise inhibited due to such infection, we have discussed the possible role of sulfatides that biologically occur in the fetal adnexa (placentatrophoblasts /amnion/chorion-umbilical cord), in containing HIV infection as a potential safer alternative to the ART regimens currently approved to be clinically practiced. Lastly, we have discussed the complementary and alternative medicine (CAM) therapies such as evidence based yoga and ayurveda as add-on to ART in potential elimination of MTCT of HIV infection. Out of a total of 150 children delivered by HIV infected mothers, 13 children were found to be positive as determined by the dried blood smear (DBS) for virological testing

    Summary This report updates and combines into one document earlier versions of guidelines for preventing and treating opportunistic infections (OIs) among HIV-exposed and HIV-infected children, last published in 2002 and 2004, respectively. These guidelines are intended for use by clinicians and other health-care workers providing medical care for HIV-exposed and HIV-infected children in the United States. The guidelines discuss opportunistic pathogens that occur in the United States and one that might be acquired during international travel (i.e., malaria). Topic areas covered for each OI include a brief description of the epidemiology, clinical presentation, and diagnosis of the OI in children; prevention of exposure; prevention of disease by chemoprophylaxis and/or vaccination; discontinuation of primary prophylaxis after immune reconstitution; treatment of disease; monitoring for adverse effects during treatment; management of treatment failure; prevention of disease recurrence; and discontinuation of secondary prophylaxis after immune reconstitution. A separate document about preventing and treating of OIs among HIV-infected adults and postpubertal adolescents (Guidelines for the Prevention and Treatment of Opportunistic Infections in HIV-Infected Adults and Adolescents) was prepared by a working group of adult HIV and infectious disease specialists. The guidelines were developed by a panel of specialists in pediatric HIV infection and infectious diseases (the Pediatric Opportunistic Infections Working Group) from the U.S. government and academic institutions. For each OI, a pediatric specialist with content-matter expertise reviewed the literature for new information since the last guidelines were published; they then proposed revised recommendations at a meeting at the National Institutes of Health (NIH) in June 2007. After these presentations and discussions, the guidelines underwent further revision, with review and approval by the Working Group, and final

    Objectives We investigated immune determinants of antibody responses and B-cell memory to pH1N1 vaccine in HIV-infected children. Methods Ninety subjects 4 to <25 years of age received two double doses of pH1N1 vaccine. Serum and cells were frozen at baseline, after each vaccination, and at 28 weeks post-immunization. Hemagglutination inhibition (HAI) titers, avidity indices (AI), B-cell subsets, and pH1N1 IgG and IgA antigen secreting cells (ASC) were measured at baseline and after each vaccination. Neutralizing antibodies and pH1N1-specific Th1, Th2 and Tfh cytokines were measured at baseline and post-dose 1. Results At entry, 26 (29%) subjects had pH1N1 protective HAI titers (≥1:40). pH1N1-specific HAI, neutralizing titers, AI, IgG ASC, IL-2 and IL-4 increased in response to vaccination (p<0.05), but IgA ASC, IL-5, IL-13, IL-21, IFNγ and B-cell subsets did not change. Subjects with baseline HAI ≥1:40 had significantly greater increases in IgG ASC and AI after immunization compared with those with HAI <1:40. Neutralizing titers and AI after vaccination increased with older age. High pH1N1 HAI responses were associated with increased IgG ASC, IFNγ, IL-2, microneutralizion titers, and AI. Microneutralization titers after vaccination increased with high IgG ASC and IL-2 responses. IgG ASC also increased with high IFNγ responses. CD4% and viral load did not predict the immune responses post-vaccination, but the B-cell distribution did. Notably, vaccine immunogenicity increased with high CD19+CD21+CD27+% resting memory, high CD19+CD10+CD27+% immature activated, low CD19+CD21-CD27-CD20-% tissue-like, low CD19+CD21-CD27-CD20-% transitional and low CD19+CD38+HLADR+% activated B-cell subsets. Conclusions HIV-infected children on HAART mount a broad B-cell memory response to pH1N1 vaccine, which was higher for subjects with baseline HAI≥1:40 and increased with age, presumably due to prior exposure to pH1N1 or to other influenza vaccination/infection.

    Migrants represent around one third of patients newly diagnosed with HIV in Spain and they constitute a population with higher vulnerability to its negative consequences due to the socio-cultural, economical, working, administrative and legal contexts. Migrants are diagnosed later, which worsens their individual prognosis and facilitates the maintenance of the HIV epidemic. In spite of the different barriers they experience to access healthcare in general, and HIV-related services in particular, access to antiretroviral treatment has been similar to that of the autochthonous population. However, benefits of treatment have been not, with women in general and men from Sub-Saharan Africa exhibiting the worse response to treatment. We need to proactively promote earlier diagnosis of HIV infection, the adoption of preventive measures to avoid new infections, and to deliver accessible, adapted and high-quality health-care.

    Background The use of combination antiretroviral therapy (cART) comprising three antiretroviral medications from at least two classes of drugs is the current standard treatment for HIV infection in adults and children. Current World Health Organization (WHO) guidelines for antiretroviral therapy recommend early treatment regardless of immunologic thresholds or the clinical condition for all infants (less than one years of age) and children under the age of two years. For children aged two to five years current WHO guidelines recommend (based on low quality evidence) that clinical and immunological thresholds be used to identify those who need to start cART (advanced clinical stage or CD4 counts ≤ 750 cells/mm3 or per cent CD4 ≤ 25%). This Cochrane review will inform the current available evidence regarding the optimal time for treatment initiation in children aged two to five years with the goal of informing the revision of WHO 2013 recommendations on when to initiate cART in children. Objectives To assess the evidence for the optimal time to initiate cART in treatment-naive, HIV-infected children aged 2 to 5 years. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, the AEGIS conference database, specific relevant conferences, www.clinicaltrials.gov, the World Health Organization International Clinical Trials Registry platform and reference lists of articles. The date of the most recent search was 30 September 2012. Selection criteria Randomised controlled trials (RCTs) that compared immediate with deferred initiation of cART, and prospective cohort studies which followed children from enrolment to start of cART and on cART. Data collection and analysis Two review authors considered studies for inclusion in the review, assessed the risk of bias, and extracted data on the primary outcome of death from all causes and several secondary outcomes, including incidence of CDC category C and B clinical events and

    Introduction Streptococcus pneumoniae is the commonest cause of bacteremic pneumonia among HIV-infected persons. As more countries with high HIV prevalence are implementing infant pneumococcal conjugate vaccine (PCV) programs, we aimed to describe the baseline clinical characteristics of adult invasive pneumococcal disease (IPD) in the pre-PCV era in South Africa in order to interpret potential indirect effects following vaccine use. Methods National, active, laboratory-based surveillance for IPD was conducted in South Africa from 1 January 2003 through 31 December 2008. At 25 enhanced surveillance (ES) hospital sites, clinical data, including HIV serostatus, were collected from IPD patients ≥ 5 years of age. We compared the clinical characteristics of individuals with IPD in those HIV-infected and -uninfected using multivariable analysis. PCV was introduced into the routine South African Expanded Program on Immunization (EPI) in 2009. Results In South Africa, from 2003–2008, 17 604 cases of IPD occurred amongst persons ≥ 5 years of age, with an average incidence of 7 cases per 100 000 person-years. Against a national HIV-prevalence of 18%, 89% (4190/4734) of IPD patients from ES sites were HIV-infected. IPD incidence in HIV-infected individuals is 43 times higher than in HIV-uninfected persons (52 per 100 000 vs. 1.2 per 100 000), with a peak in the HIV-infected elderly population of 237 per 100 000 persons. Most HIV-infected individuals presented with bacteremia (74%, 3 091/4 190). HIV-uninfected individuals were older; and had more chronic conditions (excluding HIV) than HIV-infected persons (39% (210/544) vs. 19% (790/4190), p<0.001). During the pre-PCV immunization era in South Africa, 71% of serotypes amongst HIV-infected persons were covered by PCV13 vs. 73% amongst HIV-uninfected persons, p = 0.4, OR 0.9 (CI 0.7–1.1). Conclusion Seventy to eighty-five percent of adult IPD in the pre-PCV era were vaccine serotypes and 93% of cases had recognized risk

    HIV-infected individuals have poor responses to inactivated influenza vaccines. To evaluate the potential role of regulatory T (Treg) and B cells (Breg), we analyzed their correlation with humoral and cell-mediated immune (CMI) responses to pandemic influenza (pH1N1) monovalent vaccine in HIV-infected children and youth. Seventy-four HIV-infected, 4- to 25-y old participants in a 2-dose pH1N1 vaccine study had circulating and pH1N1-stimulated Treg and Breg measured by flow cytometry at baseline, post-dose 1 and post-dose 2. Concomitantly, CMI was measured by ELISPOT and flow cytometry; and antibodies by hemagglutination inhibition (HAI). At baseline, most of the participants had pH1N1-specific IFNγ ELISPOT responses, whose magnitude positively correlated with the baseline pH1N1, but not with seasonal H1N1 HAI titers. pH1N1-specific IFNγ ELISPOT responses did not change post-dose 1 and significantly decreased post-dose 2. In contrast, circulating CD4+CD25+% and CD4+FOXP3+% Treg increased after vaccination. The decrease in IFNγ ELISPOT results was marginally associated with higher pH1N1-specific CD19+FOXP3+ and CD4+TGFβ+% Breg and Treg, respectively. In contrast, increases in HAI titers post-dose 1 were associated with significantly higher circulating CD19+CD25+% post-dose 1, whereas increases in IFNγ ELISPOT results post-dose 1 were associated with higher circulating CD4+/C8+CD25+FOXP3+%. In conclusion, in HIV-infected children and youth, influenza-specific Treg and Breg may contribute to poor responses to vaccination. However, robust humoral and CMI responses to vaccination may result in increased circulating Treg and/or Breg, establishing a feed-back mechanism. PMID:23370281

    Background We described malnutrition and the effect of age at antiretroviral therapy (ART) initiation on catch-up growth over 24 months among HIV-infected children enrolled in the IeDEA West African paediatric cohort (pWADA). Methods Malnutrition was defined at ART initiation (baseline) by a Z-score <-2 SD, according to three anthropometric indicators: Weight-for-age (WAZ) for underweight, Height-for-age (HAZ) for stunting, and Weight-for-Height/BMI-for-age (WHZ/BAZ) for wasting. Kaplan-Meier estimates for catch-up growth (Z-score ≥-2 SD) on ART, adjusted for gender, immunodeficiency and malnutrition at ART initiation, ART regimen, time period and country, were compared by age at ART initiation. Cox proportional hazards regression models determined predictors of catch-up growth on ART over 24 months. Results Between 2001 and 2012, 2004 HIV-infected children < 10 years of age were included. At ART initiation, 51% were underweight, 48% were stunted and 33% were wasted. The 24-month adjusted estimates for catch-up growth were 69% (95% confidence interval [CI]: 57;80), 61% (95%CI: 47;70), and 90% (95%CI: 76;95) for WAZ, HAZ, and WHZ/BAZ, respectively. Adjusted catch-up growth was more likely for children <5 years of age at ART initiation compared to children ≥5 years for WAZ, HAZ (P<0.001), and for WHZ/BAZ (P = 0.026). Conclusions Malnutrition among these children is an additional burden that has to be urgently managed. Despite a significant growth improvement after 24 months on ART, especially in children <5 years, a substantial proportion of children still never achieved catch-up growth. Nutritional care should be part of the global healthcare of HIV-infected children in sub-Saharan Africa. PMID:25955835

    Summary Most infants born to human immunodeficiency virus (HIV)-infected women escape HIV infection. Infants evade infection despite an immature immune system and, in the case of breastfeeding, prolonged repetitive, exposure. If infants become infected, the course of their infection and response to treatment differs dramatically depending upon the timing (in utero, intrapartum, or during breastfeeding) and potentially the route of their infection. Perinatally acquired HIV infection occurs during a critical window of immune development. HIV’s perturbation of this dynamic process may account for the striking age-dependent differences in HIV disease progression. HIV infection also profoundly disrupts the maternal immune system upon which infants rely for protection and immune instruction. Therefore, it is not surprising that infants who escape HIV infection still suffer adverse effects. In this review, we highlight the unique aspects of pediatric HIV transmission and pathogenesis with a focus on mechanisms by which HIV infection during immune ontogeny may allow discovery of key elements for protection and control from HIV.

    Background Approximately one-third of HIV-infected children experience virological failure within two years of initiating antiretroviral therapy (ART). We determined the probability of switch to second-line ART or viral load (VL) re-suppression without switch among children who experienced VL rebound on first-line ART in an observational cohort in the UK/Ireland. Methods Children with VL rebound (confirmed VL>400c/ml following suppression <400c/ml) on first-line ART were included. Competing risk analysis estimated the probability of: switch to second-line; confirmed re-suppression (two consecutive VL<400c/ml) without switch; and continued VL>400c/ml without switch. Predictors of time to switch were assessed. Findings Of 900 children starting first-line ART who had VL<400c/ml by one year, 170 (19%) experienced VL rebound by median [IQR] 20·6 months [9·7-40·5]. At rebound, median age was 10·6 years [5·6-13·4], VL 3·6 log10c/ml [3·1-4·2], and CD4% 24 [17-32]. Eighty-nine (52%) switched to second-line ART at median 4·9 months [1·7-13·4] after VL rebound, 53 (31%) re-suppressed without switch (61% of those on PI-based and 24% of those on NNRTI-based first-line regimens), while 28 (16%) neither re-suppressed nor switched. At 12 months after rebound, probabilities of switch or re-suppression without switch were 38% (95% CI 30-45) and 27% (95% CI 21-34), respectively. Faster time to switch was associated with higher VL (p<0·0001), later calendar year (p=0·02) at VL rebound, and NNRTI- or triple NRTI- versus PI-based first-line (p=0·001). Interpretation One-third of children with VL rebound re-suppressed without switch. The possibility of re-suppression with adherence support should be considered prior to switching.

    Background The WHO recommends boosted protease inhibitor (bPI)-based highly active antiretroviral therapy (HAART) after failing non-nucleoside reverse transcriptase inhibitor (NNRTI) treatment. We examined outcomes of this regimen in Asian HIV-infected children. Methods Children from five Asian countries in the TREAT Asia Pediatric HIV Observational Database (TApHOD) with ≥24 weeks of NNRTI-based HAART followed by ≥24 weeks of bPI-based HAART were eligible. Primary outcomes were the proportions with virologic suppression (HIV-RNA <400 copies/ml) and immune recovery (CD4% ≥25% if age <5 years and CD4 count ≥500 cells/mm3 if age ≥5 years) at 48 and 96 weeks. Results Of 3422 children, 153 were eligible; 52% were female. At switch, median age was 10 years, 26% were in WHO stage 4. Median weight-for-age z-score (WAZ) was −1.9 (n=121), CD4% was 12.5% (n=106), CD4 count was 237 (n=112) cells/mm3, and HIV-RNA was 4.6 log10copies/ml (n=61). The most common PI was lopinavir/ritonavir (83%). At 48 weeks, 61% (79/129) had immune recovery, 60% (26/43) had undetectable HIV-RNA and 73% (58/79) had fasting triglycerides ≥130mg/dl. By 96 weeks, 70% (57/82) achieved immune recovery, 65% (17/26) virologic suppression, and hypertriglyceridemia occurred in 66% (33/50). Predictors for virologic suppression at week 48 were longer duration of NNRTI-based HAART (p=0.006), younger age (p=0.007), higher WAZ (p=0.020), and HIV-RNA at switch <10,000 copies/ml (p=0.049). Conclusion In this regional cohort of Asian children on bPI-based second-line HAART, 60% of children tested had immune recovery by one year, and two-thirds had hyperlipidemia, highlighting difficulties in optimizing second-line HAART with limited drug options.

    Objectives To assess the impact of exposure to single-dose nevirapine (sdNVP) on virological response in young Ugandan/Zimbabwean children (<3 years) initiating antiretroviral therapy (ART), and investigate other predictors of response. Design Observational analysis within the ARROW randomised trial. Methods sdNVP exposure was ascertained by caregiver’s self-report when the child initiated NNRTI based ART. Viral load (VL) was assayed retrospectively over median 4.1 years follow-up. Multivariable logistic regression models were used to identify independent predictors of VL <80 copies/ml 48 and 144 weeks after ART initiation (backwards elimination, exit p=0.1). Results Median (IQR) age at ART initiation was 17 (10-23) months in 78 sdNVP exposed children versus 21 (14-27) months in 289 non-exposed children (36% vs 20% <12 months). At week 48, 49/73 (67%) sdNVP exposed and 154/272 (57%) non-exposed children had VL<80 copies/ml (adjusted (a)OR=2.34 [1.26-4.34] p=0.007); 79% and 77% had VL<400copies/ml. Suppression was significantly lower in males (p=0.009), those with higher pre-ART VL (p=0.001), taking syrups (p=0.05) and with lower self-reported adherence (p=0.04). At week 144, 55/73 (75%) exposed and 188/272 (69%) non-exposed had <80 copies/ml (aOR=1.75 [0.93-3.29] p=0.08). There was no difference between children with and without previous sdNVP exposure in intermediate/high-level resistance to NRTIs (p>0.3) or NNRTIs (p>0.1) (n=88) at week 144. Conclusion Given the limited global availability of lopinavir/ritonavir, its significant formulation challenges in young children, and the significant paediatric treatment gap, tablet fixed-dose-combination nevirapine-based ART remains a good alternative to syrup lopinavir-based ART for children, particularly those over one year and even if exposed to sdNVP.

    Background. PACTG (Pediatric AIDS Clinical Trials Group) 225, a multicenter, randomized, open-label trial in the United States evaluated reactogenicity and immunogenicity of 2 vaccination regimens: monovalent measles vaccine (Attenuvax) at 6 months of age and measles, mumps, and rubella, live attenuated (MMRII) vaccine at 12 months of age (2D), or only MMRII at 12 months of age (1D) in human immunodeficiency virus–infected (HIV-infected) (POS) and uninfected (NEG) children in the pre–highly active antiretroviral therapy (pre-HAART) period. Methods. Plaque-reduction neutralization (PRN) of measles-neutralizing antibody titers were evaluated at study weeks 0, 6, 26, 32, 52, and 130 (∼3 years of age). Results. The 110 subjects included: 65 2DNEG; 30 1DNEG; 7 2DPOS and 8 1DPOS. Vaccinations (n = 175) were associated with no adverse experiences >Grade 2 except for Grade 3 fever (n = 2, 1 1DPOS and 1 1DNEG). Six weeks after Attenuvax, all 2DPOS subjects (7/7) seroresponded (PRN titers ≥120 mIU/mL) with median titers significantly exceeding 2DNEG titers (2115 vs 628 mIU/mL, respectively; P = .023). At ∼3 years of age, 67% 1DPOS (4/6) and 83% 2DPOS (4/5) subjects maintained titers ≥120 mIU/mL. Prevaccination titers ≥25 mIU/mL among 2DNEG subjects correlated inversely with the likelihood of achieving titers ≥120 mIU/mL (56% vs 90%; P = .004). Conclusions. Among HIV-infected children pre-HAART, Attenuvax at 6 months was well tolerated and immunogenic. These data support the current World Health Organization (WHO) recommendation to administer a first dose of measles vaccine at 6 months of age to HIV-infected children. PMID:21666159

    Background. Identifying determinants of morbidity and mortality may help target future interventions for human immunodeficiency virus (HIV)–infected children. Methods. CD4+ T-cell count, HIV viral load, and levels of biomarkers (C-reactive protein, tumor necrosis factor α [TNF-α], interleukin 6 [IL-6], and soluble CD14) and interleukin 7 were measured at antiretroviral therapy (ART) initiation in the ARROW trial (case-cohort design). Cases were individuals who died, had new or recurrent World Health Organization clinical stage 4 events, or had poor immunological response to ART. Results. There were 115 cases (54 died, 45 had World Health Organization clinical stage 4 events, and 49 had poor immunological response) and 485 controls. Before ART initiation, the median ages of cases and controls were 8.2 years (interquartile range [IQR], 4.4–11.4 years) and 5.8 years (IQR, 2.3–9.3 years), respectively, and the median percentages of lymphocytes expressing CD4 were 4% (IQR, 1%–9%) and 13% (IQR, 8%–18%), respectively. In multivariable logistic regression, cases had lower age-associated CD4+ T-cell count ratio (calculated as the ratio of the subject's CD4+ T-cell count to the count expected in healthy individuals of the same age; P < .0001) and higher IL-6 level (P = .002) than controls. Clustering biomarkers and age-associated CD4+ and CD8+ T-cell count ratios identified 4 groups of children. Group 1 had the highest frequency of cases (41% cases; 16% died) and profound immunosuppression; group 2 had similar mortality (23% cases; 15% died), but children were younger, with less profound immunosuppression and high levels of inflammatory biomarkers and malnutrition; group 3 comprised young children with moderate immunosuppression, high TNF-α levels, and high age-associated CD8+ T-cell count ratios but lower frequencies of events (12% cases; 7% died); and group 4 comprised older children with low inflammatory biomarker levels, lower HIV viral loads, and good

    The objective of the study was to investigate the relationship between various CD4+ T cell subsets and the ability of peripheral blood mononuclear cells (PBMC) to proliferate to several stimuli in vertically human immunodeficiency virus type 1 (HIV-1)-infected children. We studied 29 HIV-1-infected children on highly active antiretroviral therapy (HAART) (median duration: 12·3 months). T cell subsets were determined by flow cytometry. Plasma viral load (VL) was quantified using a standardized molecular method. Proliferative responses were evaluated by [3H]-thymidine incorporation. Decreased proliferative responses of PBMC to pokeweed mitogen (PWM) were found for HIV-1-infected children in Centers for Disease Control (CDC) clinical categories B and C when compared to the control group (P < 0·05). Similarly, children with ≤ 15% CD4+ T cells showed a decrease in proliferative responses to PWM (P < 0·01), anti-CD3 + anti-CD28 (P < 0·01) and phytohaemagglutinin (PHA) (P < 0·05) with respect to the control group and to children with CD4+ T cells ≥ 25%. Proliferative responses to PWM, anti-CD3+, anti-CD28 and PHA had a statistically significant positive correlation with CD3+/mm3, CD4+/mm3, % CD4 T cells, CD4/CD8 ratio and the percentage of naive T cell subsets (CD4+CD45RO−HLA-DR−, CD4+ CD45RA+ CD62L+, CD4+ CD45RA+), CD4+ CD62L+ and CD4+ T cells co-expressing CD38+ (CD4+ HLA-DR−CD38+, CD4+ CD38+). Moreover, we found a negative correlation between PBMC proliferative responses and % CD8 T cells, memory, memory-activated and activated CD4+ T cell subsets. Lower proliferative responses to PWM (P < 0·01) and PHA (P < 0·01) were associated with higher VL. Our data show that higher proliferative responses to PWM, anti-CD3 + anti-CD28 and PHA are associated with both non-activated and naive CD4+ T cell subsets in HIV-1-infected children on HAART.

    The Access-to-Treatment research initiative of the Population Council's Horizons program undertook 11 projects across Asia and sub-Saharan Africa from 2002 to 2008. The projects included a variety of cross-sectional exploratory studies, situation analyses, and longitudinal randomized, controlled intervention studies that examined service delivery, community awareness, health-seeking behaviors, adherence, cost, and other factors affecting treatment for adults and children infected with human immunodeficiency virus (HIV). This article summarizes the key findings and lessons learned from these projects, and examines cross-cutting issues such as stigma, quality of life, and sexual-risk behaviors among people living with HIV and acquired immunodeficiency syndrome on antiretroviral therapy. The article concludes with recommendations for evidence-based programming and future research around treatment for both children and adults. PMID:20297759

    Background We determined the prevalence and incidence of liver dysfunction prior to and after initiation of combination antiretroviral therapy (cART) in the TREAT Asia Pediatric HIV Observational Database (TApHOD). Methods Data from children initiated on cART between 2–18 years of age with baseline alanine aminotransferase (ALT) available prior to and at least once after cART initiation in TApHOD between 2008–2012 were analyzed. Prevalence and incidence of liver dysfunction, and biomarkers including the aspartate aminotransferase (AST) to platelet ratio index (APRI) and FIB4 index were assessed. Results Data from 1930 children were included. Their median age was 6.9 years; 49% were male; 98% were perinatally infected; and 94% were initiated on non-nucleoside reverse transcriptase-based cART regimens. Prior to cART, the prevalence of ALT ≥ 3 times the upper limit of normal (*ULN) was 5.8%. There were 8.5% of children with APRI >1.5 (suggestive of liver fibrosis), and 2.7% with FIB4 index >1.3 (predictive of possible cirrhosis). Among the 1143 cases with normal baseline ALT (≤1*ULN), the incidence of ALT 3*ULN after cART was 1.19/1000 person-months (95% CI 0.93–1.51). Two of 350 with available tests (0.6%) met Hy’s law (ALT >3*ULN and total bilirubin >2*ULN). By multivariate analysis, baseline hemoglobin <7.5 g/dL was a predictor of ALT >3*ULN, while age 5–9 years at cART initiation was protective for liver dysfunction. Conclusions We demonstrated a low prevalence and incidence of liver dysfunction before and after cART initiation in children with normal baseline chemistries. In this population facing life-long cART, prospective surveillance for emergence of liver disease is warranted. PMID:25970117

    Although the number of new infections has declined recently, women still constitute almost half of the world's 34 million people with HIV infection, and HIV remains the leading cause of death among women of reproductive age. Prevention research has made considerable progress during the past few years in addressing the biological, behavioral and social factors that influence women's vulnerability to HIV infection. Nevertheless, substantial work still must be done in order to implement scientific advancements and to resolve the many questions that remain. This article highlights some of the recent advances and persistent gaps in HIV prevention research for women and outlines key research and policy priorities. PMID:23764631

    Talaromyces (Penicillium) marneffei is an important pathogenic thermally dimorphic fungus causing systemic mycosis in Southeast Asia. The clinical significance of T. marneffei became evident when the human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome epidemic arrived in Southeast Asia in 1988. Subsequently, a decline in the incidence of T. marneffei infection among HIV-infected patients was seen in regions with access to highly active antiretroviral therapy and other control measures for HIV. Since the 1990s, an increasing number of T. marneffei infections have been reported among non-HIV-infected patients with impaired cell-mediated immunity. Their comorbidities included primary adult-onset immunodeficiency due to anti-interferon-gamma autoantibodies and secondary immunosuppressive conditions including other autoimmune diseases, solid organ and hematopoietic stem cell transplantations, T-lymphocyte-depleting immunsuppressive drugs and novel anti-cancer targeted therapies such as anti-CD20 monoclonal antibodies and kinase inhibitors. Moreover, improved immunological diagnostics identified more primary immunodeficiency syndromes associated with T. marneffei infection in children. The higher case-fatality rate of T. marneffei infection in non-HIV-infected than HIV-infected patients might be related to delayed diagnosis due to the lack of clinical suspicion. Correction of the underlying immune defects and early use of antifungals are important treatment strategies. Clinicians should be familiar with the changing epidemiology and clinical management of T. marneffei infection among non-HIV-infected patients. PMID:26956447

    The great success in the prevention and treatment of pediatric HIV in high resource countries, and now in low resource countries, has changed the face of the HIV epidemic in children from one of near certain mortality to that of a chronic disease. However, these successes pose new challenges as perinatally HIV-infected youth survive into adulthood. Increased survival of HIV-infected children is associated with challenges in maintaining adherence to what is likely life-long therapy, and in selecting successive antiretroviral drug regimens, given the limited availability of pediatric formulations, limitations in pharmacokinetic and safety data of drugs in children, and the development of extensive drug resistance in multi-drug-experienced children. Pediatric HIV care must now focus on morbidity related to long-term HIV infection and its treatment. Survival into adulthood of perinatally HIV-infected youth in high resource countries provides important lessons about how the epidemic will change with increasing access to antiretroviral therapy for children in low resource countries. This series of papers will focus on issues related to management of perinatally infected youth and young adults. PMID:23782484

    The live-attenuated influenza vaccine (LAIV) has generally been more efficacious than the inactivated vaccine in children. However, LAIV is not recommended for HIV-infected children because of insufficient data. We compared cellular, humoral, and mucosal immune responses to the 2013–2014 LAIV quadrivalent (LAIV4) in HIV-infected and uninfected children 2–25 years of age (yoa). We analyzed the responses to the vaccine H1N1 (H1N1-09), to the circulating H1N1 (H1N1-14), which had significant mutations compared to H1N1-09 and to B Yamagata (BY), which had the highest effectiveness in 2013–2014. Forty-six HIV-infected and 56 uninfected participants with prior influenza immunization had blood and nasal swabs collected before and after LAIV4 for IFNγ T and IgG/IgA memory B-cell responses (ELISPOT), plasma antibodies [hemagglutination inhibition (HAI) and microneutralization (MN)], and mucosal IgA (ELISA). The HIV-infected participants had median CD4+ T cells = 645 cells/μL and plasma HIV RNA = 20 copies/mL. Eighty-four percent were on combination anti-retroviral therapy. Regardless of HIV status, significant increases in T-cell responses were observed against BY, but not against H1N1-09. H1N1-09 T-cell immunity was higher than H1N1-14 both before and after vaccination. LAIV4 significantly increased memory IgG B-cell immunity against H1N1-14 and BY in uninfected, but not in HIV-infected participants. Regardless of HIV status, H1N1-09 memory IgG B-cell immunity was higher than H1N1-14 and lower than BY. There were significant HAI titer increases after vaccination in all groups and against all viruses. However, H1N1-14 MN titers were significantly lower than H1N1-09 before and after vaccination overall and in HIV-uninfected vaccinees. Regardless of HIV status, LAIV4 increased nasal IgA concentrations against all viruses. The fold-increase in H1N1-09 IgA was lower than BY. Overall, participants <9 yoa had decreased BY-specific HAI and nasal IgA responses

    Objectives: Tuberculosis (TB) is estimated to be the leading cause of HIV-related deaths globally. However, since HIV-associated TB frequently remains unascertained, we systematically reviewed autopsy studies to determine the true burden of TB at death. Methods: We systematically searched Medline and Embase databases (to end 2013) for literature reporting on health facility-based autopsy studies of HIV-infected adults and/or children in resource-limited settings. Using forest plots and random-effects meta-analysis, we summarized the TB prevalence found at autopsy and used meta-regression to explore variables associated with autopsy TB prevalence. Results: We included 36 eligible studies, reporting on 3237 autopsies. Autopsy TB prevalence was extremely heterogeneous (range 0–64.4%), but was markedly higher in adults [pooled prevalence 39.7%, 95% confidence interval (CI) 32.4–47.0%] compared to children (pooled prevalence 4.5%, 95% CI 1.7–7.4%). Post-mortem TB prevalence varied by world region, with pooled estimates in adults of 63.2% (95% CI 57.7–68.7%) in South Asia (n = 2 studies); 43.2% (95% CI 38.0–48.3) in sub-Saharan Africa (n = 9 studies); and 27.1% (95% CI 16.0–38.1%) in the Americas (n = 5 studies). Autopsy prevalence positively correlated with contemporary estimates of national TB prevalence. TB in adults was disseminated in 87.9% (82.2–93.7%) of cases and was considered the cause of death in 91.4% (95% CI 85.8–97.0%) of TB cases. Overall, TB was the cause of death in 37.2% (95% CI 25.7–48.7%) of adult HIV/AIDS-related deaths. TB remained undiagnosed at death in 45.8% (95% CI 32.6–59.1%) of TB cases. Conclusions: In resource-limited settings, TB accounts for approximately 40% of facility-based HIV/AIDS-related adult deaths. Almost half of this disease remains undiagnosed at the time of death. These findings highlight the critical need to improve the prevention, diagnosis and treatment of HIV-associated TB globally. PMID

    HIV Patient care should include psychological and psychiatric care, which is necessary for early detection thereof. Should suicidal ideation occur, refer the patient to a psychiatric unit. Pharmacological treatment is recommended when there is comorbidity with moderate or severe depression. You should look for the aetiology of neuropsychiatric disorder before using psychoactive drugs in HIV patients. The overall management of the health of HIV adolescents should include an assessment of mental health, environmental stressors and support systems. Training in the management of the patient both own emotions is critical to getting to provide optimal care. These new guidelines updated previous recommendations regarding psychiatric and psychological disorders, including the most common pathologies in adults and children. PMID:26409724

    BACKGROUND Data describing the true extent of antiretroviral therapy (ART)-induced dyslipidemia and insulin resistance in perinatally-infected children on ART in Africa is sparse. METHODS Fasting total cholesterol, LDL, HDL, triglycerides, insulin and glucose were performed on the first 100, of 190 pediatric ART clinic attendees. Diet assessment was performed by a trained dietician. Lipoatrophy was formally graded by consensus between two expert HIV pediatricians. Durations of previous ART exposures, clinical stage, pre-ART viral load, nadir and current CD4 were recorded. Dual energy X-ray Absorptiometry (DEXA) was performed on a subset of 42 patients selected semi-randomly. RESULTS Prevalences of insulin resistance, abnormal total cholesterol, LDL, HDL and triglyceride were 10%, 13%, 12%, 13 % and 9% respectively. Overall, 40% had at least one lipid abnormality or insulin resistance. Adjusted mean LDL cholesterol increased by 0.24mmol/L for each additional year of cumulative lopinavir/r exposure (p=0.03) after correcting for age, gender, body mass index, previous stavudine exposure, age at ART initiation, dietary fat and refined carbohydrate, while adjusted mean LDL cholesterol was 0.9mmol/L higher in children exposed to efavirenz within the previous six months (p=0.02). Adjusting for age, gender and ethnicity, DEXA revealed that greater trunk fat and lower peripheral subcutaneous fat were associated with elevated triglycerides but not with total cholesterol, LDL, HDL or HOMA. Similarly, the presence of visually obvious lipoatrophy was associated with elevated triglycerides but not with total cholesterol, LDL, HDL, HOMA or lactate. CONCLUSIONS Prevalences of insulin resistance and dyslipidemia were high. Cumulative lopinovir is an independent risk factor for dyslipidemia, with efavirenz exposure having only transitory effect.

    Summary Recent advances in the immunology, pathogenesis, and prevention of human immunodeficiency virus (HIV) infection continue to reveal clues to the mechanisms involved in the progressive immunodeficiency attributed to infection but more importantly have shed light on the correlates of immunity to infection and disease progression. HIV selectively infects, eliminates, and/or dysregulates several key cells of the human immune system, thwarting multiple arms of the host immune response, and inflicting severe damage to mucosal barriers, resulting in tissue infiltration of ‘symbiotic’ intestinal bacteria and viruses that essentially become opportunistic infections promoting systemic immune activation. This leads to activation and recruitment or more target cells for perpetuating HIV infection, resulting in persistent, high level viral replication in lymphoid tissues, rapid evolution of resistant strains, and continued evasion of immune responses. However, vaccine studies and studies of spontaneous controllers are finally providing correlates of immunity from protection and disease progression, including virus-specific CD4+ T-cell responses, binding antibodies, innate immune responses, and generation of antibodies with potent antibody-dependent cell-mediated cytotoxicity activity. Emerging correlates of immunity indicate that prevention of HIV infection may be possible through effective vaccine strategies that protect and stimulate key regulatory cells and immune responses in susceptible hosts. Further, immune therapies specifically directed towards boosting specific aspects of the immune system may eventually lead to a cure for HIV-infected patients. PMID:23772612

    Although human immunodeficiency virus (HIV) infection is a worldwide problem, its prevalence and pattern vary from country to country. Accordingly, the risk to international travellers of acquiring HIV infection also varies widely in different parts of the world, and depends principally on their behaviour. The risk of sexual acquisition of HIV infection can be virtually eliminated by avoiding penetrative sexual intercourse with intravenous drug users and persons who have had multiple sexual partners (such as prostitutes) or reduced by the use of condoms. The risk of parenteral exposure to HIV can be reduced by avoiding parenteral drug use and behaviour that is likely to lead to injury (with its attendant risk of requiring blood transfusion) and by seeking medical facilities with adequate capabilities to screen blood donors for HIV and to sterilize instruments. HIV screening of international travellers is an ineffective, costly, and impractical public health strategy for limiting the worldwide spread of HIV infection. Travellers infected with HIV require specialized advice regarding health precautions, prophylactic medications, and immunization. PMID:2194689

    P1066 is an open-label study of raltegravir in HIV+ youth, ages 4 weeks-18 years. Here we summarize P1066 pharmacokinetic (PK) data and a population PK model for the pediatric chewable tablet and oral granules. Raltegravir PK parameters were calculated using non-compartmental analysis. A two-compartment model was developed using data from P1066 and an adult study of the pediatric formulations. Inter-individual variability was described by an exponential error model, and residual variability was captured by an additive/proportional error model. Twelve-hour concentrations (C12hr) were calculated from the model-derived elimination rate constant and 8-hour observed concentration. Simulated steady-state concentrations were analyzed by non-compartmental analysis. Target area-under-the-curve (AUC0-12hr) and C12hr were achieved in each cohort. For the pediatric formulations, geometric mean AUC0-12hr values were 18.0–22.6 μM*hr across cohorts, and C12hr values were 71–130 nM, with lower coefficients of variation vs the film-coated tablet. A two-compartment model with first-order absorption adequately described raltegravir plasma PK in pediatric and adult patients. Weight was a covariate on clearance and central volume, and incorporated using allometric scaling. Raltegravir chewable tablets and oral granules exhibited PK parameters consistent with those from prior adult studies and older children in P1066, as well as lower variability than the film-coated tablet.

  7. Spatiotemporal dynamics of HIV infection

    Strain, Matthew Carl

    Mathematical models of the dynamics of infection with the human immunodeficiency virus (HIV) have contributed to tremendous advances over the past 20 years. This thesis extends this previous work by exploring the importance of spatial heterogeneity in HIV infection both in vitro and in vivo in patients treated with highly-active antiretroviral therapy. Viral infections propagate locally in space, yet HIV infection has been widely regarded as equilibrated over the entire body of an infected patient. This dissertation constructs and explores a cellular automata model of viral spread at the cellular level. Coupling the automata to a blood compartment represented by a differential equation leads to a whole-body model of HIV infection that explicitly includes spatial effects at both the cellular and tissue levels. These models are tested by comparison with experimental data. A central prediction of the spatial model is that, due to competition between Brownian motion and viral lability, HIV infectivity increases with target cell density. This production is verified in a series of in vitro experiments in cell culture. The predicted independence of inhibitory concentrations of antiretoviral agents is verified for nevirapine, but azidothymidine inhibits HIV replication less efficiently in more dense cultures. These in vitro results suggest that systems allowing cell concentrations closer to tissue densities would better reflect virus replication kinetics, although standard measures of relative drug susceptibility may accurately reflect in vivo conditions. The coupled spatial model of in vivo dynamics is compared with novel mathematical analysis of experiments in HIV-infected patients. These analyses indicate that HIV DNA provides a useful marker of the size of long-lived cellular reservoirs of HIV. Levels of HIV DNA in peripheral blood are predictive of the average rate of residual virus production after years of treatment, regardless of whether patients initiate therapy

    ABSTRACT Each year, millions of African children receive praziquantel (PZQ) by mass drug administration (MDA) to treat schistosomiasis at a standard single dose of 40 mg/kg of body weight, a direct extrapolation from studies of adults. A higher dose of 60 mg/kg is also acceptable for refractory cases. We conducted the first PZQ pharmacokinetic (PK) and pharmacodynamic (PD) study in young children comparing dosing. Sixty Ugandan children aged 3 to 8 years old with egg patent Schistosoma mansoni received PZQ at either 40 mg/kg or 60 mg/kg. PK parameters of PZQ racemate and enantiomers (R and S) were quantified. PD outcomes were assessed by standard fecal egg counts and novel schistosome-specific serum (circulating anodic antigen [CAA]) and urine (circulating cathodic antigen [CCA]) antigen assays. Population PK and PD analyses were performed to estimate drug exposure in individual children, and the relationship between drug exposure and parasitological cure was estimated using logistic regression. Monte Carlo simulations were performed to identify better, future dosing regimens. There was marked PK variability between children, but the area under the concentration-time curve (AUC) of PZQ was strongly predictive of the parasitological cure rate (CR). Although no child achieved antigenic cure, which is suggestive of an important residual adult worm burden, higher AUC was associated with greater CAA antigenic decline at 24 days. To optimize the performance of PZQ, analysis of our simulations suggest that higher doses (>60 mg/kg) are needed, particularly in smaller children. PMID:27507822

    Advances in access to HIV prevention and treatment have reduced vertical transmission of HIV, with most children born to HIV-infected parents being HIV-uninfected themselves. A major challenge that HIV-infected parents face is disclosure of their HIV status to their predominantly HIV-uninfected children. Their children enter middle childhood and early adolescence facing many challenges associated with parental illness and hospitalization, often exacerbated by stigma and a lack of access to health education and support. Increasingly, evidence suggests that primary school-aged children have the developmental capacity to grasp concepts of health and illness, including HIV, and that in the absence of parent-led communication and education about these issues, HIV-exposed children may be at increased risk of psychological and social problems. The Amagugu intervention is a six-session home-based intervention, delivered by lay counselors, which aims to increase parenting capacity to disclose their HIV status and offer health education to their primary school-aged children. The intervention includes information and activities on disclosure, health care engagement, and custody planning. An uncontrolled pre–post-evaluation study with 281 families showed that the intervention was feasible, acceptable, and effective in increasing maternal disclosure. The aim of this paper is to describe the conceptual model of the Amagugu intervention, as developed post-evaluation, showing the proposed pathways of risk that Amagugu aims to disrupt through its intervention targets, mechanisms, and activities; and to present a summary of results from the large-scale evaluation study of Amagugu to demonstrate the acceptability and feasibility of the intervention model. This relatively low-intensity home-based intervention led to: increased HIV disclosure to children, improvements in mental health for mother and child, and improved health care engagement and custody planning for the child.

    Background. We conducted a systematic review and meta-analysis to evaluate the incidence and prevalence of 14 opportunistic infections (OIs) and other infections as well as the impact of antiretroviral therapy (ART) among human immunodeficiency virus (HIV)–infected children (aged <18 years) in low- and middle-income countries (LMICs), to understand regional burden of disease, and inform delivery of HIV services. Methods. Eligible studies described the incidence of OIs and other infections in ART-naive and -exposed children from January 1990 to November 2013, using Medline, Global Health, Embase, Cumulative Index to Nursing and Allied Health Literature, Web of Knowledge, and Literatura Latino Americana em Ciências da Saúde databases. Summary incident risk (IR) and prevalent risk for each OI in ART-naive and ART-exposed children were calculated, and unadjusted odds ratios calculated for impact of ART. The number of OI cases and associated costs averted were estimated using the AIDS impact model. Results. We identified 4542 citations, and 88 studies were included, comprising 55 679 HIV-infected children. Bacterial pneumonia and tuberculosis were the most common incident and prevalent infections in both ART-naive and ART-exposed children. There was a significant reduction in IR with ART for the majority of OIs. There was a smaller impact on bacterial sepsis and pneumonia, and an increase observed for varicella zoster. ART initiation based on 2010 World Health Organization guidelines criteria for ART initiation in children was estimated to potentially avert >161 000 OIs (2013 UNAIDS data) with estimated cost savings of at least US$17 million per year. Conclusions. There is a decrease in the risk of most OIs with ART use in HIV-infected children in LMICs, and estimated large potential cost savings in OIs averted with ART use, although there are greater uncertainties in pediatric data compared with that of adults.

    Background Few studies have reported CD4%- and age-stratified rates of WHO Stage 3 (WHO3) events, WHO Stage 4 (WHO4) events, tuberculosis (TB), and mortality in HIV-infected infants before initiation of antiretroviral therapy (ART). Methods HIV-infected children enrolled before 1 year of age in the International Epidemiologic Databases to Evaluate AIDS (IeDEA) East Africa region (10/01/2002-11/30/2008) were included. We estimated incidence rates of earliest clinical event (WHO3, WHO4, and TB), prior to ART initiation per local guidelines, stratified by current age (< or ≥6 months) and current CD4% (<15%, 15–24%, ≥25%). CD4%-stratified mortality rates were estimated separately for children who did not experience a clinical event (“background” mortality) and for children who experienced an event, including “acute” mortality (≤30 days post-event) and “later” mortality (>30 days post-event). Results Among 847 children (median enrollment age: 4.8 months; median pre-ART follow-up: 10.8 months; 603 (71%) with ≥1 CD4% recorded), event rates were comparable for those aged <6 and ≥6 months. Current CD4% was associated with risk of WHO4 events for children <6 months old, and with all evaluated events for children ≥6 months old (p<0.05). “Background” mortality was 3.7–8.4/100py. “Acute” mortality (≤30 days post-event) was 33.8/100py (after TB) and 41.1/100py (after WHO3 or WHO4). “Later” mortality (>30 days post-event) ranged by CD4% from 4.7–29.1/100py. Conclusions In treatment-naïve, HIV-infected infants, WHO3, WHO4, and TB events were common before and after 6 months of age and led to substantial increases in mortality. Early infant HIV diagnosis and treatment are critically important, regardless of CD4%. PMID:24378935

    Objective To investigate the effects of HIV infection in children on heart electrical conduction, particularly to delineate the effects of HIV infection from treatment. Methods On a 12-lead ECG, available for 37 antiretroviral therapy (ART) naïve, 42 ART-exposed vertically-acquired HIV-infected and 50 healthy children in Jakarta, Indonesia, we measured cardiac conduction parameters: PR, QRS, and QTc (corrected using Bazett's formula) intervals. The associations between HIV infection/treatment status and ECG intervals were evaluated using general linear modelling with further adjustment for potential confounders or intermediary variables. Findings are presented as (adjusted) mean differences between each of the two HIV groups and healthy children. Results Although not exceeding the clinical threshold for long QT (QTc >460 ms for girls and >440 ms for boys) compared to healthy children, mean QTc intervals were longer in ART-naïve (difference 18.2 ms, 95% CI 7.0 to 29.3) and, to greater extent, in ART-exposed HIV-infected children (difference 28.9 ms, 19.3 to 38.5). Following adjustment for RR interval, age and height, prolongation of PR interval was seen only in ART-naïve HIV-infected children (difference 12.9 ms, 2.4 to 23.3). Cardiac mass/function, high-sensitive C reactive protein, cholesterol and glycated haemoglobin levels, systolic and diastolic blood pressures, or postnatal parental smoking exposure did not affect these associations. No difference in the QRS interval was observed between groups. Conclusions Prolongation of the QTc interval occurs in ART-naïve HIV-infected children and, to a greater extent, in the ART-exposed children, whereas a longer PR interval appears to be seen only among ART-naïve HIV-infected children.

    The incidence and severity of infections in childhood is typically greater in males. The basis for these observed sex differences is not well understood, and potentially may facilitate novel approaches to reducing disease from a range of conditions. We here investigated sex differences in HIV-infected children in relation to antiretroviral therapy (ART) initiation and post-treatment outcome. In a South African cohort of 2,101 HIV-infected children, we observed that absolute CD4+ count and CD4% were significantly higher in ART-naïve female, compared to age-matched male, HIV-infected children. Absolute CD4 count and CD4% were also significantly higher in HIV-uninfected female versus male neonates. We next showed that significantly more male than female children were initiated on ART (47% female); and children not meeting criteria to start ART by >5 yrs were more frequently female (59%; p<0.001). Among ART-treated children, immune reconstitution of CD4 T-cells was more rapid and more complete in female children, even after adjustment for pre-ART absolute CD4 count or CD4% (p=0.011, p=0.030, respectively). However, while ART was initiated as a result of meeting CD4 criteria less often in females (45%), ART initiation as a result of clinical disease in children whose CD4 counts were above treatment thresholds occurred more often in females (57%, p<0.001). The main sex difference in morbidity observed in children initiating ART above CD4 thresholds, above that of TB disease, was as a result of wasting and stunting observed in females with above-threshold CD4 counts (p=0.002). These findings suggest the possibility that optimal treatment of HIV-infected children might incorporate differential CD4 treatment thresholds for ART initiation according to sex. PMID:26151555

    The review summarizes data of recent studies on the impact of human gene polymorphisms on the possibility of HIV infection, as well as the specific features of its pathogenesis, the efficiency of HIV infection treatment and the likelihood of its complication. Main information on the mechanisms responsible for viral penetration into the sensitive cells, for immune response development and involvement of HLA and KIR molecules in this process are briefly outlined. Idea on major cell proteins affecting drug metabolism and excretion and encoding for their genes are generalized. There are many examples that show how different human gene alleles and their combinations affect the nature of the pathogenetic process and the occurrence and degree of adverse reactions. The first example of successfully using the prognostic genetic analysis (HLA-B*5701) registered in 2008 to upgrade the quality of HIV infection treatment is described in detail. Basic requirements for further genetic tests to use the optimal antiretroviral therapy schemes and to reduce its hazardous effects are formulated. PMID:20481056

    Worldwide, more than three million children are infected with HIV, 90% of whom live in sub-Saharan Africa. As the HIV epidemic matures and antiretroviral treatment is scaled up, children with HIV are reaching adolescence in large numbers. The growing population of adolescents with perinatally acquired HIV infection living within this region presents not only unprecedented challenges but also opportunities to learn about the pathogenesis of HIV infection. In this Review, we discuss the changing epidemiology of paediatric HIV and the particular features of HIV infection in adolescents in sub-Saharan Africa. Longstanding HIV infection acquired when the immune system is not developed results in distinctive chronic clinical complications that cause severe morbidity. As well as dealing with chronic illness, HIV-infected adolescents have to confront psychosocial issues, maintain adherence to drugs, and learn to negotiate sexual relationships, while undergoing rapid physical and psychological development. Context-specific strategies for early identification of HIV infection in children and prompt linkage to care need to be developed. Clinical HIV care should integrate age-appropriate sexual and reproductive health and psychological, educational, and social services. Health-care workers will need to be trained to recognise and manage the needs of these young people so that the increasing numbers of children surviving to adolescence can access quality care beyond specialist services at low-level health-care facilities.

    The Caribbean is a multi-ethnic region with many different cultural differences. The majority of the population is of African descent, but there are also other ethnic groups present such as Indians, Chinese, Syrians and Europeans. The Caribbean region is influenced by countries such as the USA, Great Britain, France and Holland. The countries of the Caribbean have a serious problem with HIV infection and AIDS. The epidemiology of HIV infection in this region, is different from most other parts of the world in that the mode of spread does not easily fit into any of the three WHO patterns. This review shows that the infection initially started in the homosexual/bisexual community, but since then, it has moved to the heterosexual population and this form of contact is now the main mode of transmission of the virus. The Governments of the Caribbean countries have realized the extent of the problem and have taken measures to try to control the epidemic. PMID:8031923

    OBJECTIVE: To describe factors related to reproductive decision-making among HIV-infected women. MATERIALS AND METHODS: A sample of HIV-infected women (N=104) who received care at an HIV clinic in the southern United States were interviewed about their reproductive decision-making. Women who became pregnant subsequent to HIV diagnosis were compared to women who did not become pregnant, and women who underwent a sterilization procedure subsequent to HIV diagnosis were compared to women who did not get sterilized. RESULTS: Compared to women who did not get pregnant after receiving an HIV diagnosis, women who became pregnant were more likely to be young, single, diagnosed earlier in the epidemic and to have more recently used a noninjecting drug. Among women who did not get pregnant, 63% reported their diagnosis greatly affected that decision. Having a partner who wants more children was not associated with pregnancy. Compared to women who did not get sterilized after learning their HIV status, women who did get sterilized tended to be Baptist and already had a prior live birth. Neither a woman's desire nor her partner's desire for more children was associated with sterilization. CONCLUSIONS: HIV is an important influence on HIV-infected women's reproductive choices, regardless of the decision being made. Reproductive counseling by HIV care providers needs to be sensitive to all the issues faced by these women. PMID:16353661

    Bacteremia may be inappropriately treated as malaria in children admitted with a febrile illness in Africa. We determined the prevalence, clinical features, and spectrum of bacteremia among febrile children younger than 5 years of age admitted with a negative malaria test, but prescribed antimalarials at a referral hospital in Jinja, Uganda. After initial evaluation, a blood sample was drawn from 250 children for a complete blood count and bacterial culture. Of 250 samples cultured, 15 grew organisms presumed to be skin contaminants, and of the remaining 235 samples, 45 (19.1%) had bacteremia. Staphylococcus aureus (42%), non-typhoidal Salmonella (24%), Pseudomonas aeruginosa (11%), and Streptococcus pneumoniae (9%) were the most common bacterial isolates. On multivariate analysis, history of weight loss (odds ratio [OR] = 2.75; 95% confidence interval [CI] = 1.27-5.95), presence of pulmonary crackles (OR = 3.63; 95% CI = 1.40-9.45), and leukocytosis (OR = 2.21; 95% CI = 1.09-4.47) were independent predictors of bacteremia. At a referral hospital in Uganda, bacteremia was a remarkably common finding in children with febrile illness who were treated for malaria despite negative malaria test results. PMID:26055736

    HIV infection has been traditionally considered to be an absolute contraindication for solid organ transplantation. Recent advances in HIV treatment, as highly active antiretroviral therapy (HAART), significantly reduced HIV-related mortality and morbidity. At the same time the number of HIV-infected patients with end-stage organ diseases constantly increased. Current data describing solid organ transplantation in HIV-infected patients demonstrated comparable outcome to that in the HIV-negative population. In light of this, solid organ transplantation should be considered as a treatment option for selected HIV-positive patients with end-stage organ disease. PMID:15171000

The first case dated May 1979 was retroactively diagnosed in an Haitian parturient, thank to her serum kept in the Pasteur institute of Cayenne. 44 women got their pregnancy during their HIV infection: 5 with clinical and biological evidence of AIDS, 7 developed AIDS after getting pregnant, and 10 out of these 12 women died. All of them were from a rather low social group and, generally, were not married. 43 are black (40 Haitians and 3 Guyanese Creoles), one is Indian and presented some psychic disorders. The mean age was 32 1/2 (from 15 to 51 years old). 55 babies were born: 12 developed AIDS (6 died during the first 15 months of their life); 14 are HIV +, 3 stillborns, 4 never tested and 22 developed negative reaction (with ELISA and Western-Blot) between 7.5 and 10 months of their life. Two Hutchinson's triads were observed. Prurigo is the most commonly skin manifestation observed. PMID:2725245

    Background Prevention of unplanned pregnancies is a critical element in the prevention of mother-to-child transmission of HIV infection, but its potential has not been fully realized. We assessed the utilization of family planning (FP) and fertility desires among women of reproductive age by HIV status. Methods We selected a nationally representative sample of households using a stratified 2-stage cluster design and surveyed women aged 15–49 years. We administered questionnaires and examined predictors of current use of FP and desire for children among sexually active women with known HIV infection and women who were HIV uninfected. Results Of 3583 respondents, 68.2% were currently using FP, and 57.7% did not desire children in the future. Among women who did not desire children in the future, 70.9% reported that they were using FP, including 68.7% of women with known HIV infection and 71.0% of women who were HIV uninfected. Women with known HIV infection had similar odds of using FP as women with no HIV infection (odds ratio, 1.12; 95% confidence interval: 0.81 to 1.54). Women with no HIV infection had significantly higher adjusted odds of desiring future children (adjusted OR, 2.27; 95% confidence interval: 1.31 to 3.93) than women with known HIV infection. Conclusions There is unmet need for FP for HIV-infected women, underscoring a gap in the national prevention of mother-to-child transmission of HIV strategy. Efforts to empower HIV-infected women to prevent unintended pregnancies should lead to expanded access to contraceptive methods and take into account women’s reproductive intentions. PMID:24413040

    OBJECTIVE: To determine the validity of an algorithm used by primary care health workers to identify children with symptomatic human immunodeficiency virus (HIV) infection. This HIV algorithm is being implemented in South Africa as part of the Integrated Management of Childhood Illness (IMCI), a strategy that aims to improve childhood morbidity and mortality by improving care at the primary care level. As AIDS is a leading cause of death in children in southern Africa, diagnosis and management of symptomatic HIV infection was added to the existing IMCI algorithm. METHODS: In total, 690 children who attended the outpatients department in a district hospital in South Africa were assessed with the HIV algorithm and by a paediatrician. All children were then tested for HIV viral load. The validity of the algorithm in detecting symptomatic HIV was compared with clinical diagnosis by a paediatrician and the result of an HIV test. Detailed clinical data were used to improve the algorithm. FINDINGS: Overall, 198 (28.7%) enrolled children were infected with HIV. The paediatrician correctly identified 142 (71.7%) children infected with HIV, whereas the IMCI/HIV algorithm identified 111 (56.1%). Odds ratios were calculated to identify predictors of HIV infection and used to develop an improved HIV algorithm that is 67.2% sensitive and 81.5% specific in clinically detecting HIV infection. CONCLUSIONS: Children with symptomatic HIV infection can be identified effectively by primary level health workers through the use of an algorithm. The improved HIV algorithm developed in this study could be used by countries with high prevalences of HIV to enable IMCI practitioners to identify and care for HIV-infected children. PMID:14997238

    Introduction Through The Global Plan Towards the Elimination of New HIV Infections Among Children by 2015 and Keeping their Mothers Alive, leaders have called for broader action to strengthen the involvement of communities. The Global Plan aspires to reduce new HIV infections among children by 90 percent, and to reduce AIDS-related maternal mortality by half. This article summarizes the results of a review commissioned by UNAIDS to help inform stakeholders on promising practices in community engagement to accelerate progress towards these ambitious goals. Methods This research involved extensive literature review and key informant interviews. Community engagement was defined to include participation, mobilization and empowerment while excluding activities that involve communities solely as service recipients. A promising practice was defined as one for which there is documented evidence of its effectiveness in achieving intended results and some indication of replicability, scale up and/or sustainability. Results Promising practices that increased the supply of preventing mother-to-child transmission (PMTCT) services included extending community cadres, strengthening linkages with community- and faith-based organizations and civic participation in programme monitoring. Practices to improve demand for PMTCT included community-led social and behaviour change communication, peer support and participative approaches to generate local solutions. Practices to create an enabling environment included community activism and government leadership for greater involvement of communities. Committed leadership at all levels, facility, community, district and national, is crucial to success. Genuine community engagement requires a rights-based, capacity-building approach and sustained financial and technical investment. Participative formative research is a first step in building community capacity and helps to ensure programme relevance. Building on existing structures, rather

    Background. Parainfluenza virus (PIV) is a common cause of acute respiratory tract infections, but little is known about PIV infection in children and adults in Africa, especially in settings where human immunodeficiency virus (HIV) prevalence is high. Methods. We conducted active, prospective sentinel surveillance for children and adults hospitalized with severe acute respiratory illness (SARI) from 2009 to 2014 in South Africa. We enrolled controls (outpatients without febrile or respiratory illness) to calculate the attributable fraction for PIV infection. Respiratory specimens were tested by multiplex real-time reverse-transcription polymerase chain reaction assay for parainfluenza types 1, 2, and 3. Results. Of 18 282 SARI cases enrolled, 1188 (6.5%) tested positive for any PIV type: 230 (19.4%) were type 1; 168 (14.1%) were type 2; 762 (64.1%) were type 3; and 28 (2.4%) had coinfection with 2 PIV types. After adjusting for age, HIV serostatus, and respiratory viral coinfection, the attributable fraction for PIV was 65.6% (95% CI [confidence interval], 47.1–77.7); PIV contributed to SARI among HIV-infected and -uninfected children <5 years of age and among individuals infected with PIV types 1 and 3. The observed overall incidence of PIV-associated SARI was 38 (95% CI, 36–39) cases per 100 000 population and was highest in children <1 year of age (925 [95% CI, 864–989] cases per 100 000 population). Compared with persons without HIV, persons with HIV had an increased relative risk of PIV hospitalization (9.4; 95% CI, 8.5–10.3). Conclusions. Parainfluenza virus causes substantial severe respiratory disease in South Africa among children <5 years of age, especially those that are infected with HIV. PMID:26566534
