Severe anemia is a major cause of sickness and death in African children, yet the causes of anemia in this population have been inadequately studied. We conducted a case-control study of 381 preschool children with severe anemia (hemoglobin concentration, <5.0 g per deciliter) and 757 preschool children without severe anemia in urban and rural settings in Malawi. Causal factors previously associated with severe anemia were studied. The data were examined by multivariate analysis and structural equation modeling. Bacteremia (adjusted odds ratio, 5.3; 95% confidence interval [CI], 2.6 to 10.9), malaria (adjusted odds ratio, 2.3; 95% CI, 1.6 to 3.3), hookworm (adjusted odds ratio, 4.8; 95% CI, 2.0 to 11.8), human immunodeficiency virus infection (adjusted odds ratio, 2.0; 95% CI, 1.0 to 3.8), the G6PD -202/-376 genetic disorder (adjusted odds ratio, 2.4; 95% CI, 1.3 to 4.4), vitamin A deficiency (adjusted odds ratio, 2.8; 95% CI, 1.3 to 5.8), and vitamin B 12 deficiency (adjusted odds ratio, 2.2; 95% CI, 1.4 to 3.6) were associated with severe anemia. Folate deficiency, sickle cell disease, and laboratory signs of an abnormal inflammatory response were uncommon. Iron deficiency was not prevalent in case patients (adjusted odds ratio, 0.37; 95% CI, 0.22 to 0.60) and was negatively associated with bacteremia. Malaria was associated with severe anemia in the urban site (with seasonal transmission) but not in the rural site (where malaria was holoendemic). Seventy-six percent of hookworm infections were found in children under 2 years of age. There are multiple causes of severe anemia in Malawian preschool children, but folate and iron deficiencies are not prominent among them. Even in the presence of malaria parasites, additional or alternative causes of severe anemia should be considered.

To document the immunization rates, factors associated with incomplete immunization, and missed opportunities for immunizations in children affected by HIV presenting for routine outpatient follow-up. A cross-sectional study of immunization status of children affected by HIV presenting for routine outpatient care was conducted. Two hundred and six HIV affected children were enrolled. The median age of children in this cohort was 6 y. One hundred ninety seven of 206 children were HIV infected, nine were HIV exposed, but indeterminate. Fifty (25 %) children had incomplete immunizations per the Universal Immunization Program (UIP) of India. Hundred percent of children had received OPV. Ninety three percent of children got their UIP vaccines from a government clinic. Children with incomplete immunization were older, median age of 8 compared to 5 (p = 0.003). Each year of maternal education increased the odds of having a child with complete UIP immunizations by 1.18 (p = 0.008)-children of mothers with 6 y of education compared to those with no education were seven times more likely to have complete UIP vaccine status. The average number of visits to the clinic by an individual child in a year was 4. This represents 200 missed opportunities for immunizations. HIV infected children are at risk for incomplete immunization coverage though they regularly access medical care. Including routine immunizations, particularly catch-up immunizations in programs for HIV infected children maybe an effective way of protecting these children from vaccine preventable disease.

Background: Selenium is found in soils and is essential for human antioxidant defense and immune function. In Malawi, low soil selenium and dietary intakes coupled with low plasma selenium concentrations in HIV infection could have negative consequences for the health of HIV-infected mothers and their exclusively breastfed infants. Objective: We tested the effects of lipid-based nutrient supplements (LNS) that contained 1.3 times the Recommended Dietary Allowance of sodium selenite and antiretroviral drugs (ARV) on maternal plasma and breast-milk selenium concentrations. Design: HIV-infected Malawian mothers in the Breastfeeding, Antiretrovirals, and Nutrition study were randomly assigned at delivery to receive: LNS, ARV, LNS and ARV, or a control. In a subsample of 526 mothers and their uninfected infants, we measured plasma and breast-milk selenium concentrations at 2 or 6 (depending on the availability of infant samples) and 24 wk postpartum. Results: Overall, mean (±SD) maternal (range: 81.2 ± 20.4 to 86.2 ± 19.9 μg/L) and infant (55.6 ± 16.3 to 61.0 ± 15.4 μg/L) plasma selenium concentrations increased, whereas breast-milk selenium concentrations declined (14.3 ± 11.5 to 9.8 ± 7.3 μg/L) from 2 or 6 to 24 wk postpartum (all P < 0.001). Compared with the highest baseline selenium tertile, low and middle tertiles were positively associated with a change in maternal plasma or breast-milk selenium from 2 or 6 to 24 wk postpartum (both P < 0.001). With the use of linear regression, we showed that LNS that contained selenium and ARV were not associated with changes in maternal plasma and breast-milk selenium, but maternal selenium concentrations were positively associated with infant plasma selenium at 2 or 6 and 24 wk postpartum (P < 0.001) regardless of the study arm. Conclusions: Selenite supplementation of HIV-infected Malawian women was not associated with a change in their plasma or breast-milk selenium concentrations. Future research should examine

Pediatric HIV is growing at an alarming rate in developing countries. Due to their compromised immune status, children infected with HIV are prone to a number of opportunistic infections. Oral manifestations are the first signs of the disease in many of them. To assess the oral mucosal status of Indian children with HIV, based on their CD4 cell counts. Two hundred and twenty one HIV infected children aged 6-18 years from various HIV centers, were divided into three groups, based on their CD4 cell counts; Group 1: ≥500, Group 2: 201-499 and Group 3: ≤200 cells. The children in each group were further considered as 'prior to antiretroviral treatment (ART)' and 'on ART'. Oral mucosal examination was done based on presumptive criteria given by Ramos-Gomez for diagnosis of oro-facial lesions commonly associated with HIV infection in children. Data obtained was subjected to statistical analysis. Angular cheilitis and pseudomembranous candidiasis were the frequently seen oral lesions. Children with CD4 cell count ≥500 had significantly fewer oral lesions each. A high percentage of HIV-infected children were affected with oral mucosal lesions. There was a significant association between immune status and frequency of oral lesions. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

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.

Objectives: To describe the head growth of children according to maternal and child HIV infection status. Design: Longitudinal analysis of head circumference data from 13 647 children followed from birth in the ZVITAMBO trial, undertaken in Harare, Zimbabwe, between 1997 and 2001, prior to availability of antiretroviral therapy (ART) or cotrimoxazole prophylaxis. Methods: Head circumference was measured at birth, then at regular intervals through 24 months of age. Mean head circumference-for-age Z-scores (HCZ) and prevalence of microcephaly (HCZ < −2) were compared between HIV-unexposed children, HIV-exposed uninfected (HEU) children and children infected with HIV in utero (IU), intrapartum (IP) and postnatally (PN). Results: Children infected with HIV in utero had head growth restriction at birth. Head circumference Z-scores remained low throughout follow-up in IP children, whereas they progressively declined in IU children. During the second year of life, HCZ in the PN group declined, reaching a similar mean as IP-infected children by 21 months of age. Microcephaly was more common among IU and IP children than HIV-uninfected children through 24 months. HEU children had significantly lower head circumferences than HIV-unexposed children through 12 months. Conclusion: HIV-infected children had lower head circumferences and more microcephaly than HIV-uninfected children. Timing of HIV acquisition; influenced HCZ, with those infected before birth having particularly poor head growth. HEU children had poorer head growth until 12 months of age. Correlations between head growth and neurodevelopment in the context of maternal/infant HIV infection, and further studies from the current ART era, will help determine the predictive value of routine head circumference measurement.

Njau, J C; Aboud, S

2010-09-01

Tuberculosis (TB)-human immunodeficiency virus (HIV) co-infection is an important public health problem. Diagnosis of TB in children usually follows discovery of an adult case, and relies on clinical presentation, sputum examination and chest radiograph. However, clinical features are non-specific, chest radiographs are difficult to interpret, and routine laboratory tests are not helpful. The aim of the current study was to determine the prevalence of TB in HIV-infected children below 14 years attending a tertiary hospital. A cross-sectional study was conducted in HIV-infected children below 14 years of age at Muhimbili National Hospital, in Dar es Salaam, Tanzania, between July 2008 and January 2009. Information on socio-demographic and anthropometric characteristics was collected using a structured questionnaire. Following assessment of clinical presentation, physical examination, tuberculin skin test, and chest radiograph were performed for each child. Two consecutive sputum specimens and blopd sample were collected for microscopy and culture, and CD4 T-lymphocyte percentage test, respectively. Chi-square test was used to compare differences in proportions. Odds ratio (OR) and their 95% confidence interval (CI) are presented as the risk estimator. Of 182 HIV-infected children enrolled in the study, 104 (57.1%) were males. Overall, thirty-seven (20.3%) children had TB. The prevalence of TB was highest in males (78.4%) compared to females (p = 0.003). There was a higher proportion of TB (45.9%) in the age group below 24 months compared to other age groups (p = 0.001). Male gender, history of positive TB contact and severe immunosuppression were found to be significant risk factors for TB while use of antiretroviral therapy was found to be associated with decreased risk for TB. One-fifth of children had TB/HIV co-infection. Presence of four or more clinical manifestations and a low CD4+ T-lymphocyte percentage can be used to predict active TB in HIV-infected

HIV-infected children have impaired antibody responses after exposure to certain antigens. Our aim was to determine whether HIV-infected children had lower varicella zoster virus (VZV) antibody levels compared with HIV-infected adults or healthy children and, if so, whether this was attributable to an impaired primary response, accelerated antibody loss, or failure to reactivate the memory VZV response. In a prospective, cross-sectional and retrospective longitudinal study, we compared antibody responses, measured by enzyme-linked immunosorbent assay (ELISA), elicited by VZV infection in 97 HIV-infected children and 78 HIV-infected adults treated with antiretroviral therapy, followed over 10 years, and 97 age-matched healthy children. We also tested antibody avidity in HIV-infected and healthy children. Median anti-VZV immunoglobulin G (IgG) levels were lower in HIV-infected children than in adults (264 vs. 1535 IU/L; P<0.001) and levels became more frequently unprotective over time in the children [odds ratio (OR) 17.74; 95% confidence interval (CI) 4.36-72.25; P<0.001]. High HIV viral load was predictive of VZV antibody waning in HIV-infected children. Anti-VZV antibodies did not decline more rapidly in HIV-infected children than in adults. Antibody levels increased with age in healthy (P=0.004) but not in HIV-infected children. Thus, antibody levels were lower in HIV-infected than in healthy children (median 1151 IU/L; P<0.001). Antibody avidity was lower in HIV-infected than healthy children (P<0.001). A direct correlation between anti-VZV IgG level and avidity was present in HIV-infected children (P=0.001), but not in healthy children. Failure to maintain anti-VZV IgG levels in HIV-infected children results from failure to reactivate memory responses. Further studies are required to investigate long-term protection and the potential benefits of immunization. © 2011 British HIV Association.

Oral diseases in the HIV infected children though commonly encountered are under researched and often overlooked by physicians in developing countries. The aim of this study is to document the types and frequency of oral lesions in HIV infected children and examine the effects of management with HAART on their rates. A cross sectional study designed to identify the oral lesions in consecutive HIV infected children and their distribution at a Paediatric Anti-retroviral clinic. Information on oral disease and clinical features of the subjects were obtained by history and clinical examination and laboratory investigations by the pediatricians and dental surgeons. The 58 children studied consisted of 34 boys and 24 girls with their ages ranging from 3 months to 13 years. Thirty seven (63.8%) of the 58 children had oral diseases. Enamel hypoplasia, candidiasis, caries, angular chelitis, and herpes labialis were the most common oral lesions found in the patients. Oral soft tissue lesions were less frequently encountered among children on HAART. Statistical significance was recorded among those infected with candidiasis. More than 60% of the children diagnosed with oral disease had no knowledge of the state of their oral health before the study. Oral diseases are very common amongst the children studied. Awareness of oral disease among the children and their caregivers is low. Administration of HAART may have a preventive effect on the development of oral soft tissue disease. There is a need to integrate dental care into the paediatric HIV care programs.

Worldwide about 2.5 million children younger than 15 years of age are living with HIV, and more than 2.3 million of them live in sub-Saharan Africa. Antiretroviral therapy has reduced mortality among HIV-infected children, and as they survive into adolescence, disclosing to them their diagnosis has emerged as a difficult issue, with many adolescents unaware of their diagnosis. There is a need to build an empirical foundation for strategies to appropriately inform infected children of their diagnosis, particularly in South Africa, which has the largest number of HIV-positive people in the world. As a step toward developing such strategies, we conducted a study in Eastern Cape Province, South Africa to identify beliefs about disclosing HIV diagnosis to HIV-infected children among caregivers, health-care providers, and HIV-positive children who knew their diagnosis. We implemented 7 focus groups with 80 participants: 51 caregivers in 4 groups, 24 health-care providers in 2 groups, and 5 HIV-positive children in 1 group. We found that although the participants believed that children from age 5 years should begin to learn about their illness, with full disclosure by age 12, they suggested that many caregivers fail to fully inform their children. The participants said that the primary caregiver was the best person to disclose. The main reasons cited for failing to disclose were (a) lack of knowledge about HIV and its treatment, (b) the concern that the children might react negatively, and (c) the fear that the children might inappropriately disclose to others, which would occasion gossip, stigmatization, and discrimination towards them and the family. We discuss the implications for developing interventions to help caregivers appropriately disclose HIV status to HIV-infected children and, more generally, communicate effectively with the children to improve their health outcomes.

To describe pediatric ART scale-up in Ethiopia, one of the 21 global priority countries for elimination of pediatric HIV infection. A descriptive analysis of routinely collected HIV care and treatment data on HIV-infected children (<15 years) enrolled at 70 health facilities in four regions in Ethiopia, January 2006-September 2013. Characteristics at enrollment and ART initiation are described along with outcomes at 1 year after enrollment. Among children who initiated ART, cumulative incidence of death and loss to follow-up (LTF) were estimated using survival analysis. 11 695 children 0-14 years were enrolled in HIV care and 6815 (58.3%) initiated ART. At enrollment, 31.2% were WHO stage III and 6.3% stage IV. The majority (87.9%) were enrolled in secondary or tertiary facilities. At 1 year after enrollment, 17.9% of children were LTF prior to ART initiation. Among children initiating ART, cumulative incidence of death was 3.4%, 4.1% and 4.8%, and cumulative incidence of LTF was 7.7%, 11.8% and 16.6% at 6, 12 and 24 months, respectively. Children <2 years had higher risk of LTF and death than older children (P < 0.0001). Children with more advanced disease and those enrolled in rural settings were more likely to die. Children enrolled in more recent years were less likely to die but more likely to be LTF. Over the last decade large numbers of HIV-infected children have been successfully enrolled in HIV care and initiated on ART in Ethiopia. Retention prior to and after ART initiation remains a major challenge. © 2017 John Wiley & Sons Ltd.

We examined whether orphaned and fostered children and children of HIV-infected parents are disadvantaged in schooling, nutrition, and health care. We analyzed data on 2,756 children aged 0-4 years and 4,172 children aged 6-14 years included in the 2003 Kenya Demographic and Health Survey, with linked anonymous HIV testing, using multivariate logistic regression. Results indicate that orphans, fostered children, and children of HIV-infected parents are significantly less likely to attend school than non-orphaned/non-fostered children of HIV-negative parents. Children of HIV-infected parents are more likely to be underweight and wasted, and less likely to receive medical care for ARI and diarrhea. Children of HIV-negative single mothers are also disadvantaged on most indicators. The findings highlight the need to expand child welfare programs to include not only orphans but also fostered children, children of single mothers, and children of HIV-infected parents, who tend to be equally, if not more, disadvantaged.

Advances in molecular diagnostics have implicated newly-discovered respiratory viruses in the pathogenesis of pneumonia. We aimed to determine the prevalence and clinical characteristics of human bocavirus (hBoV), human rhinovirus (hRV), polyomavirus-WU (WUPyV) and -KI (KIPyV) and human coronaviruses (CoV)-OC43, -NL63, -HKU1 and -229E among children hospitalized with lower respiratory tract infections (LRTI). Multiplex real-time reverse-transcriptase polymerase chain reaction was undertaken on archived nasopharyngeal aspirates from HIV-infected and -uninfected children (<2 years age) hospitalized for LRTI, who had been previously investigated for respiratory syncytial virus, human metapneumovirus, parainfluenza I-III, adenovirus and influenza A/B. At least one of these viruses were identified in 274 (53.0%) of 517 and in 509 (54.0%) of 943 LRTI-episodes in HIV-infected and -uninfected children, respectively. Human rhinovirus was the most prevalent in HIV-infected (31.7%) and -uninfected children (32.0%), followed by CoV-OC43 (12.2%) and hBoV (9.5%) in HIV-infected; and by hBoV (13.3%) and WUPyV (11.9%) in HIV-uninfected children. Polyomavirus-KI (8.9% vs. 4.8%; p = 0.002) and CoV-OC43 (12.2% vs. 3.6%; p<0.001) were more prevalent in HIV-infected than -uninfected children. Combined with previously-tested viruses, respiratory viruses were identified in 60.9% of HIV-infected and 78.3% of HIV-uninfected children. The newly tested viruses were detected at high frequency in association with other respiratory viruses, including previously-investigated viruses (22.8% in HIV-infected and 28.5% in HIV-uninfected children). We established that combined with previously-investigated viruses, at least one respiratory virus was identified in the majority of HIV-infected and HIV-uninfected children hospitalized for LRTI. The high frequency of viral co-infections illustrates the complexities in attributing causality to specific viruses in the aetiology of LRTI and may indicate a

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

The highest prevalence of HIV infection occurs in Sub-Saharan Africa and hepatitis B virus (HBV), and hepatitis C virus (HCV) prevalence are the second highest in Sub-Saharan Africa including Malawi. Health-care workers (HCWs) play an important role in the prevention of, response to, and management of these infectious diseases. There is, however, no published research about the level of knowledge and attitudes toward HIV, HBV, and HCV infection among Malawian HCWs. The purpose of this study was to explore and determine the knowledge of and attitudes toward HIV, HBV, and HCV among a targeted population of Malawian HCWs. A cross-sectional community-based participatory research with 194 HCWs was completed employing health survey method. The project was a collaborative effort between nursing faculties in the USA and Malawian. A one-way analysis of variance (ANOVA) with the Bonferroni adjustment for multiple comparisons was used to assess the differences in knowledge and attitude among three subgroups of HCWs. Of 194 of Malawian HCWs surveyed, 41% were support staff, 37% were nursing students, and 22% were health-care professionals. Both health-care professionals and support staff had high knowledge scores related to HIV/AIDS, and their attitudes were mainly positive. However, a series of one-way ANOVAs revealed significant differences in knowledge and attitude toward HIV/AIDs, HBV, and HCV among HCWs ( P < 0.01). The majority had less knowledge about HBV and HCV and more negative attitudes toward hepatitis. This study highlights the ongoing need for reducing negative attitudes toward HIV, HBV, and HCV; and providing health education among HCWs, especially focusing on HBV and HCV prevention. The findings of the research project can be used to develop interventions addressing low HBV- and HCV-related knowledge and attitudes.

Since there have been a few reports of pediatric HIV-2 infection. We therefore investigated the perinatal transmission of HIV-2 in 147 malnourished and 164 well-nourished children attending a health center in the northern part of Guinea Bissau. Specific HIV-2 antibodies were detected in 17 mothers and in 2 malnourished children, one of them with pediatric AIDS. This study demonstrates that mother to child transmission of HIV-2 infection occurs in Guinea Bissau and suggests that there is an increased likelihood of detecting HIV-2 infection in malnourished children. The high seroprevalence of HIV-2 in a rural population without known risk factors may represent a hidden threat to mother/child health.

Co-trimoxazole prophylaxis, currently recommended in HIV-exposed, uninfected (HEU) children as protection against opportunistic infections, also has some anti-malarial efficacy. We determined whether daily co-trimoxazole prophylaxis affects the natural development of antibody-mediated immunity to blood-stage Plasmodium falciparum malaria infection. Using an enzyme-linked immunosorbent assay, we measured antibodies to 8 Plasmodium falciparum antigens (AMA-1, MSP-119, MSP-3, PfSE, EBA-175RII, GLURP R0, GLURP R2 and CSP) in serum samples from 33 HEU children and 31 HIV-unexposed, uninfected (HUU) children, collected at 6, 12 and 18 months of age. Compared to HIV-uninfected children, HEU children had significantly lower levels of specific IgG against AMA-1 at 6 months (p = 0.001), MSP-119 at 12 months (p = 0.041) and PfSE at 6 months (p = 0.038), 12 months (p = 0.0012) and 18 months (p = 0.0097). No differences in the IgG antibody responses against the rest of the antigens were observed between the two groups at all time points. The breadth of specificity of IgG response was reduced in HEU children compared to HUU children during the follow up period. Co-trimoxazole prophylaxis seems to reduce IgG antibody responses to P. falciparum blood stage antigens, which could be as a result of a reduction in exposure of those children under this regime. Although antibody responses were regarded as markers of exposure in this study, further studies are required to establish whether these responses are correlated in any way to clinical immunity to malaria.

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.

L-selectin is an adhesion molecule that is responsible for the initial attachment of leukocytes to endothelium. After leukocyte activation L-selectin is endoproteolytically released from the cell surface. In order to analyze the relationship between soluble L-selectin (sL-selectin) and parameters of immune activation and disease progression, 51 HIV infected children and 15 healthy controls were studied. Serum L-selectin concentrations were significantly higher in HIV infected children than in the control group. Levels of sL-selectin were higher in HIV infected patients with severe immunologic suppression than in those with moderate or no evidence of suppression. A positive correlation between sL-selectin levels and LTCD8 counts, sL-selectin and soluble intercellular adhesion molecule-1 (sICAM-1) and immunogobulin A (IgA) levels was detected. On the contrary sL-selectin concentration did not correlate with plasmatic viral load. The correlation with parameters of immune activation may implicate involvement of sL-selectin in the immunopathogenesis of HIV infection.

Purpose of review It is 20 years since the start of the combination antiretroviral therapy (cART) era and >10 years since cART scale-up began in resource-limited settings. We examined survival of vertically HIV-infected infants and children in the cART era. Recent findings Good survival has been achieved on cART in all settings with up to ten-fold mortality reductions compared to before cART availability. Although mortality risk remains high in the first few months after cART initiation in young children with severe disease, it drops rapidly thereafter even for those who started with advanced disease, and longer term mortality risk is low. However, suboptimal retention on cART in routine programs threatens good survival outcomes and even on treatment children continue to experience high comorbidity risk; infections remain the major cause of death. Interventions to address infection risk include co-trimoxazole prophylaxis, isoniazid preventive therapy, routine childhood and influenza immunization and improving maternal survival. Summary Pediatric survival has improved substantially with cART and HIV-infected children are aging into adulthood. It is important to ensure access to diagnosis and early cART, good program retention and optimal co-morbidity prophylaxis and treatment to achieve the best possible long-term survival and health outcomes for vertically infected children.

To assess the reliability and validity of Pediatric Quality of Life Inventory 4.0 (PedsQL(TM) 4.0) in children living with HIV. Also to determine the association of HIV infection, treatment regimens, and type of care received on quality of life (QoL) in pediatric patients. Study was conducted from January to December 2008 at Dr. Ram Manohar Lohia Hospital, New Delhi, India at the HIV pediatric outpatient department (OPD). PedsQL(TM) 4.0 was administered to 100 HIV-infected and 200 uninfected children aged 8-12 years and their primary caregivers. Internal consistency reliability exceeded 0.70 for both proxy-reported and self-reported scales. Intraclass correlation coefficient demonstrated mainly larger values for parent proxy-report (interval of 0.926-0.952 with 95% confidence) than for child self-report (interval of 0.891-0.928 with 95% confidence). Factor analysis was performed and it indicated that five factors were extracted from the PedsQL(TM) 4.0 and these five factors correspond mainly to the five scales. HIV infection was associated with a negative impact on QoL among children with lower scores for physical, school, and emotional functioning and health symptoms. In contrast, uninfected children had lower social functioning scores. Our results showed antiretroviral treatment to be associated with improved QoL among HIV-infected children. We even identified infected children living at home to be at a higher distress of psychosocial functioning and health symptoms when compared with children living in care homes. PedsQL(TM) is an acceptable and valid measure of health-related quality of life (HRQoL) for HIV-infected children and uninfected group. Application of this data will be helpful for program managers to devise care and support programme for both infected and uninfected children.

Timely, accurate and affordable testing algorithms at point-of-care are critical for early infant HIV diagnosis and initiation of antiretroviral therapy in the postpartum period. We aimed to assess the utility of HIV rapid tests for young, breast-fed HIV-exposed infants in resource limited, high HIV burden settings. We collected data on the performance of 2 commonly used rapid tests (Determine and Unigold) in Malawi between 2008 and 2012 or at the University of North Carolina between 2014 and 2015. For each 3-month interval between ages 3 and 18 months, we calculated the sensitivity, specificity, positive and negative predictive values of each test compared with the HIV DNA/RNA PCR gold standard. We also assessed the utility of each rapid test to diagnose incident HIV infection during the breastfeeding period. Among 121 HIV-exposed infants who were negative at age 6 weeks, 21 (17.2%) became infected by 18 months. At 3 months of age, both rapid tests had minimal clinical value with specificity values of 7.0% [95% confidence interval (CI): 2.3-15.7] for Determine and 19.4% (95% CI: 11.1-30.5) for Unigold. Starting at age 6 and 9 months, the Unigold test could be used as a screening tool in the follow-up of HIV-exposed infants with specificity values of 83.7% (95% CI: 74.4-89.9) and 97.7% (95% CI: 94.6-99.7), respectively. Starting at age 12 months, the type of test became less important as both tests performed well in identifying HIV-free children, although both tests failed to detect some incident HIV infections. Updated guidelines for the use of rapid tests in young HIV-exposed children that explicitly take type of test and infant age into account are urgently needed to ensure optimal care for the 1.5 million HIV-exposed infants born annually.

[Recommendations for initial antiretroviral treatment in HIV-infected children. Update 2003].

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.

Background Compared to HIV-negative women, HIV-infected women have increased risk of low birth weight (LBW) and preterm delivery (PTD). We assessed whether severity of maternal HIV-1 disease was associated with LBW or PTD. Methods Secondary analysis of The Malaria and HIV in Pregnancy prospective cohort, which enrolled HIV-positive, pregnant Malawian women from 2000–2004. Included participants (n=809) were normotensive, antiretroviral treatment naïve women who delivered a live, singleton infant. Binomial regression models were used to assess the unadjusted and adjusted prevalence ratios (PRs) and 95% confidence intervals (CI) of the effect of severity of HIV-1 disease, defined by viral load and CD4-positive T-cell counts, on prevalence of LBW and PTD. Results In unadjusted analyses, among those with malaria (n=198), there was no association between severity of HIV-1 infection and LBW, while among women without malaria (n=611), we observed a harmful association between both increasing peripheral viral load and LBW (PR: 1.44 per one-log10 increase, 95% CI: 1.12, 1.86) and placental viral load and LBW (PR: 1.24 per one-log10 increase, 95% CI: 1.00, 1.53). We observed a similar association between increasing placental viral load and PTD (PR: 1.33 per one-log10 increase, 95% CI: 1.04, 1.69). These associations persisted in multivariate models adjusted for residence, maternal education, primigravid status, and maternal anemia. Conclusions In malaria-negative women, maternal HIV-1 disease severity was significantly associated with increased prevalence of LBW and PTD. Such an association was not found in the malaria-infected women. PMID:23846560

The objectives of this study were to investigate the association between HIV infection and dental caries among children in West Africa, and to identify factors associated with dental caries among HIV-infected children. We conducted a multi-center cross-sectional study in Mali, Senegal and Côte d'Ivoire with a random sample of HIV-infected children aged 5-15 years on antiretroviral therapy and their uninfected siblings. A standardized examination was performed by calibrated dentists. The association between the number of decayed, missing or filled permanent and primary teeth surfaces (DMFdefS) and HIV status was investigated by fitting multivariable zero-inflated negative binomial models, for each age group (<12 and ≥12 years). Factors associated with dental caries could be investigated only for HIV-infected children <12 years old. The sample included 420 HIV-infected children and 418 non-infected siblings. The median DMFdefS was 7 for the HIV-infected children and 2 for the uninfected siblings. The proportion of children with DMFdefS ≥1 was significantly higher among the HIV-infected children than uninfected children (86.0 percent versus 64.4 percent, P < 0.001). The HIV-infected children were less likely to be caries-free than the uninfected siblings in both age groups. We found a higher degree of caries experience among HIV-infected children < 12 years old, in whom it was associated with sweet drink consumption, history of night bottle use, immunosuppression, and younger age at study entry. Although preventable, the burden of dental disease was high in children from families affected by HIV in West Africa and was associated with HIV infection and immunosuppression. © 2017 American Association of Public Health Dentistry.

The psychosocial adjustment of 87 inner-city African American children 6-11 years old whose mothers were HIV infected was compared with that of 149 children from a similar sociodemographic background whose mothers did not report being HIV infected. Children were not identified as being HIV infected. Mother reports, child reports, and standardized reading achievement scores were used to assess 4 domains of adjustment: externalizing problems, internalizing problems, cognitive competence, and prosocial competence. The results indicated that, on average, children from both groups had elevated levels of behavior problem scores and low reading achievement scores when compared with national averages. Relative to children whose mothers were not infected, those whose mothers were HIV infected were reported to have more difficulties in all domains of psychosocial adjustment. Potential family processes that may explain the findings are discussed.

There are few studies of HIV-related neurological disorders from centres in low-income countries where facilities are available for detailed investigation. Records of all patients attending the paediatric HIV outpatient department at B. J. Wadia Hospital for Children, Mumbai between April 2000 and March 2008 were reviewed. Of 668 HIV-infected patients, 48 (7.2%) had neurological manifestations and are included in this study. Twenty-six (54.2%) children had HIV encephalopathy. Other causes of neurological manifestations include febrile convulsion in five (10.4%), bacterial meningitis in three (6.3%), epilepsy in two (4.2%), tuberculous meningitis and progressive multi-focal encephalopathy in two (4.2%) each and toxoplasmosis, vasculitis, acute demyelinating encephalomyelitis, anti-phospholipid antibody syndrome, Down's syndrome, birth asphyxia, herpes simplex encephalopathy and mitochondrial encephalopathy in one (2.1%) each. Mean (SD) age at presentation was 4.36 (3.38) years with a range of 2 months to 15 years. The common subtle neurological manifestations were abnormal deep tendon reflexes and extensor plantar reflexes. The common symptomatic manifestations were delayed milestones in 21 children (43.8%) and seizures in 19 (39.6%). Seizures were more common in males (54%) than in females (25%) (p=0.038). In children <5 years, delayed milestones was the most common manifestation while focal neurological deficits were more common in older children. Of the 13 children who received HAART, nine (60.23%) improved. Early diagnosis of neurological disorders in HIV-infected children is important for appropriate investigation and management, especially the introduction of HAART.

Children Living with HIV-Infected Adults: Estimates for 23 Countries in sub-Saharan Africa

Short, Susan E.; Goldberg, Rachel E.

2015-01-01

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

Vitamin D insufficiency and HIV infection are both risk factors for chronic disorders, so it is important to consider vitamin D status in HIV-infected patients. We prospectively investigated serum 25-hydroxyvitamin D (25(OH)D) concentrations, determined by radioimmunoassay, in 113 HIV-infected children (age≤24 years) and 54 healthy controls matched for age and phototype. We assessed the prevalence of vitamin D deficiency and insufficiency (VDD and VDI) defined as 25(OH)D titers of <10 ng/mL and between 10 and 30 ng/mL, respectively, and their predictive factors. The overall prevalence of VDD and VDI was 38.9% and 58.7%, respectively. Mean serum 25(OH)D concentrations were significantly higher in the HIV group than the control group (14.2±6.9 ng/mL vs. 10.4±5 ng/mL, P<0.001). Variables significantly associated with low serum 25(OH)D concentrations in HIV-infected children were dark phototype (P<0.001) and age (r=-0.19, P=0.03). Patients receiving efavirenz had a trend toward lower serum 25(OH)D concentrations (11.1±4.6 ng/mL vs. 14.6±7 ng/mL, P=0.1). Dark phototype was the only independent risk factor for VDD in HIV-infected children (odds ratio=14.6; 95% confidence interval: 2.4-89.9, P=0.004). VDD and VDI were common in both HIV-infected and control groups, and serum 25(OH)D concentrations were significantly lower in controls than in HIV-infected children.

Information on nutritional status of HIV infected children from India is lacking and is required before taking up nutritional supplementation trials. Thus, the aim of the present study was to assess the growth and morbidity status of HIV infected children over a period of one year in a city in southern India. This was an observational study carried out between July 2009 and February 2011, at two orphanages in Hyderabad, India. Seventy seven HIV-positive children aged between 1 and half and 15 years, both on and not on antiretroviral therapy (ART) were included. Nutritional status was assessed longitudinally for one year by weight gain, linear growth and body composition. Serum samples were analyzed for haemoglobin, micronutrients, CD4 and CD8 counts. Dietary intakes were assessed by institutional diet survey and morbidity data were recorded every day for 12 months. Mean energy intakes were less than recommended dietary allowance (RDA) in all age groups. Iron and folate intakes were less than 50 per cent of RDA; 46 (59.7%) children were stunted, 36 (46.8%) were underweight and 15 (19.5%) had low BMI for age. Anaemia was observed in 35 (45.5%) children. Micronutrient deficiencies such as vitamin D (40/77; 51.9%), vitamin A (11/77; 14.3%), folate (37/77; 48.1%), iron (38/77; 49.3%) were widely prevalent. HIV viral load was higher in children not on ART and those with morbidity. Respiratory (36.6%) and dermatological illnesses (18.8%) were the commonest presentations. Acute, chronic malnutrition and micronutrient deficiencies were common in HIV infected children, especially in those not on ART and having morbidity. With severe malnutrition being an alarming consequence of HIV, prophylactic nutritive care should be considered for integration into HIV care strategies besides initiation of ART to improve the nutritional status and quality of life of these children.

Objectives Human immunodeficiency virus (HIV)-infected children may be at risk for premature cardiovascular disease. We compared levels of biomarkers of vascular dysfunction among HIV-infected children with and without hyperlipidemia to HIV-exposed, uninfected children (HEU) enrolled in the Pediatric HIV/AIDS Cohort Study (PHACS), and determined factors associated with these biomarkers. Design Prospective cohort study Methods Biomarkers of inflammation (C-reactive protein (CRP), interleukin-6 (IL-6), and monocyte chemoattractant protein-1 (MCP1)); coagulant dysfunction (fibrinogen and P-selectin); endothelial dysfunction (soluble intracellular cell adhesion molecule-1 (sICAM), soluble vascular cell adhesion molecule-1 (sVCAM), and E-selectin); and metabolic dysfunction (adiponectin) were measured in 226 HIV-infected and 140 HEU children. Anthropometry, body composition, lipids, glucose, insulin, HIV disease severity, and antiretroviral therapy were recorded. Results The median ages were 12.3 y (HIV-infected) and 10.1 y (HEU). Body mass index (BMI) Z-scores, waist and hip circumference, and percent body fat were lower among HIV-infected. Total and non-HDL cholesterol and triglycerides were higher in HIV-infected children. HIV-infected children had higher MCP-1, fibrinogen, sICAM, and sVCAM levels. In multivariable analyses in the HIV-infected children alone, BMI z-score was associated with higher CRP and fibrinogen, but lower MCP-1 and sVCAM. Unfavorable lipid profiles were positively associated with IL6, MCP1, fibrinogen, and P- and E-selectin, whereas increased HIV viral load was associated with markers of inflammation (MCP1 and CRP) and endothelial dysfunction (sICAM and sVCAM). Conclusions HIV-infected children have higher levels of biomarkers of vascular dysfunction than do HEU children. Risk factors associated with higher biomarkers include unfavorable lipid levels and active HIV replication. PMID:22136114

Data regarding the use of QuantiFERON to assist the diagnosis of active tuberculosis (TB) in HIV-infected children are limited, especially in countries with low incidence of TB/HIV coinfection. QuantiFERON results were analyzed in 63 HIV-infected children who presented to our hospital in Paris, France. Seventeen HIV-uninfected children with active TB (4 culture-confirmed) were included for comparison. The 63 HIV-infected children (median age: 11 yr) had 113 QuantiFERON tests. Thirty-four (54%) were born in sub-Saharan Africa. Vertical HIV transmission was documented for 50 of 52 (96%) and stage III HIV-infection for 30 of 50 children (60%). Over the study period, active TB was diagnosed in 7 of 63 HIV-infected children (3 culture-confirmed). Additional ongoing or previous opportunistic infections were present in 4 of 7. QuantiFERON results were positive in 2 of 7 HIV-infected children with active TB (sensitivity: 29%) and 16 of 17 HIV-uninfected children with active TB (sensitivity: 94%). At initial QuantiFERON testing of the 63 HIV-infected children, 8 (13%) had positive results (1, active TB; 5, latent TB; 2, previous TB) and 51 (81%) had negative results. Of 33 children with repeat testing after an initially positive or negative result, the only change was one conversion from a negative to a positive result at the onset of active TB. The 4 children (6%) with indeterminate quantiFERON results had a concomitant opportunistic infection. Results of repeat testing after clinical stabilization were negative in all 4. QuantiFERON testing performed poorly for active TB diagnosis in this series of children with advanced HIV infection.

Since its development in the early 1980s, Hepatitis B virus (HBV) vaccine has been proven to be highly protective. However, its immunogenicity may be ineffective among HIV-infected children. In Morocco, HBV vaccine was introduced in 1999, and since then all infants, including vertically HIV-infected infants, have been following the vaccination schedule, implemented by the Moroccan ministry of health. An assessment of the immunization of these children is important to optimize efforts aimed at tackling Hepatitis B coinfection, within the country. Forty-nine HIV-infected children (HIV group) and 112 HIV uninfected children (control group) were enrolled in this study. Samples were tested by Elisa (Monolisa Anti-HBs, Biorad) to quantify the anti-HBs antibodies. The % of lymphocyte subsets i.e. CD4+ T cells, CD8+ T cells, B cells, and NK, was determined by flow cytometry, using CellQuest Pro software (Becton-Dickinson), and for HIV group, HIV viral load was measured by real time PCR assay (Abbott). All variables were statistically compared in the two groups. The median age was 51 ± 35 months for the HIV group and 50 ± 36 months (p > 0.05) for the control group. Female represented 63% and 41% (p = 0.01), among the HIV group and the control group, respectively. Among HIV-infected children, 71.4% (35/49) were under HAART therapy at the enrollment in the study. Seroprotection titer i.e. anti-HBs ≥10mUI/ml among control group was 76% (85/112), and only 29% (14/49) among the perinatally HIV-infected children (p < 0.0001). Lower % of CD4 + T cells was observed in HIV-infected children with a poor anti-HBs response. In this studied group, we have shown that despite the vaccination of HIV-children with HBV vaccine, 71% did not show any seroprotective response. These findings support the need for monitoring HBV vaccine response among HIV-infected children in Morocco, in order to revaccinate non-immunized children.

Predictors and consequences of childhood anaemia in settings with high HIV prevalence are not well known. The aims of the present study were to identify maternal and child predictors of anaemia among children born to HIV-infected women and to study the association between childhood anaemia and mortality. Prospective cohort study. Maternal characteristics during pregnancy and Hb measurements at 3-month intervals from birth were available for children. Information was also collected on malaria and HIV infection in the children, who were followed up for survival status until 24 months after birth. Dar es Salaam, Tanzania. The study sample consisted of 829 children born to HIV-positive women. Advanced maternal clinical HIV disease (relative risk (RR) for stage > or =2 v. stage 1: 1.31, 95 % CI 1.14, 1.51) and low CD4 cell counts during pregnancy (RR for <350 cells/mm3 v. > or =350 cells/mm3: 1.58, 95 % CI 1.05, 2.37) were associated with increased risk of anaemia among children. Birth weight <2500 g, preterm birth (<34 weeks), malaria parasitaemia and HIV infection in the children also increased the risk of anaemia. Fe-deficiency anaemia in children was an independent predictor of mortality in the first two years of life (hazard ratio 1.99, 95 % CI 1.06, 3.72). Comprehensive care including highly active antiretroviral therapy to eligible HIV-infected women during pregnancy could reduce the burden of anaemia in children. Programmes for the prevention of mother-to-child transmission of HIV and antimalarial treatment to children could improve child survival in settings with high HIV prevalence.

HIV is a stigmatizing medical condition. The concept of HIV stigma is multifaceted, with personalized stigma (perceived stigmatizing consequences of others knowing of their HIV status), disclosure concerns, negative self-image, and concerns with public attitudes described as core aspects of stigma for individuals with HIV infection. There is limited research on HIV stigma in children. The aim of this study was to test a short version of the 40-item HIV Stigma Scale (HSS-40), adapted for 8-18 years old children with HIV infection living in Sweden. A Swedish version of the HSS-40 was adapted for children by an expert panel and evaluated by think aloud interviews. A preliminary short version with twelve items covering the four dimensions of stigma in the HSS-40 was tested. The psychometric evaluation included inspection of missing values, principal component analysis (PCA), internal consistency, and correlations with measures of health-related quality of life (HRQoL). Fifty-eight children, representing 71% of all children with HIV infection in Sweden meeting the inclusion criteria, completed the 12-item questionnaire. Four items concerning participants' experiences of others' reactions to their HIV had unacceptable rates of missing values and were therefore excluded. The remaining items constituted an 8-item scale, the HIV Stigma Scale for Children (HSSC-8), measuring HIV-related disclosure concerns, negative self-image, and concerns with public attitudes. Evidence for internal validity was supported by a PCA, suggesting a three factor solution with all items loading on the same subscales as in the original HSS-40. The scale demonstrated acceptable internal consistency, with exception for the disclosure concerns subscale. Evidence for external validity was supported in correlational analyses with measures of HRQoL, where higher levels of stigma correlated with poorer HRQoL. The results suggest feasibility, reliability, as well as internal and external validity of the

As antiretroviral therapy (ART) allows the world's 2.3 million human immunodeficiency virus (HIV)-infected children to grow and thrive, these children need to be informed of their HIV status. Neither the prevalence of disclosure to children nor its impact has been evaluated in most resource-limited settings. We conducted a prospective assessment of a random sample of HIV-infected children ages 6-14 years enrolled in HIV care at a large referral clinic in Eldoret, Kenya. Clinicians administered questionnaires to children and caregivers independently at routine clinic visits to assess disclosure status, ART adherence, stigma, and depression. Children's demographic and clinical characteristics were extracted from chart review. We calculated descriptive statistics and performed logistic regression to assess the association between disclosure and other characteristics. Two hundred seventy children-caregiver dyads completed questionnaires. The mean child age was 9.3 years (standard deviation 2.6); 49% were male, and 42% were orphans. 11.1% of children had been informed of their HIV status (N = 30). Of those under 10 years, 3.3% knew their status, whereas 9.2% of 10- to 12-year-olds and 39.5% of 13- to 14-year-olds knew they had HIV. Only age was significantly associated with disclosure status in both bivariate analyses (P < .0001) and multiple logistic regression (odds ratio 1.67, 95% confidence interval 1.36-2.05) when considering social demographics, disease stage variables, adherence, stigma measures, and depression. Rates of informing children in western Kenya of their HIV status are low, even among older children. Guiding families through developmentally appropriate disclosure processes should be a key facet of long-term pediatric HIV management. © The Author 2013.

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.

Background: Little is known about the influence of antiretroviral therapy with or without micronutrient supplementation on the micronutrient concentrations of HIV-infected lactating women in resource-constrained settings. Objective: We examined associations of highly active antiretroviral therapy (HAART) and lipid-based nutrient supplements (LNS) with concentrations of selected micronutrients in HIV-infected Malawian women at 24 wk postpartum. Methods: Plasma micronutrient concentrations were measured in a subsample (n = 690) of Breastfeeding, Antiretrovirals, and Nutrition (BAN) study participants who were randomly assigned at delivery to receive HAART, LNS, HAART+LNS, or no HAART/no LNS (control). HAART consisted of protease inhibitor–based triple therapy. LNS (140 g/d) met energy and micronutrient requirements of lactation. Multivariable linear regression tested the association of HAART and LNS, plus their interaction, with micronutrient concentrations, controlling for season, baseline viral load, and baseline CD4 count. Results: We found significant HAART by LNS interactions for folate (P = 0.051), vitamin B-12 (P < 0.001), and transferrin receptors (TfRs) (P = 0.085). HAART was associated with lower folate (with LNS: −27%, P < 0.001; without LNS: −12%, P = 0.040) and higher TfR concentrations (with LNS: +14%, P = 0.004; without LNS: +28%, P < 0.001), indicating iron deficiency. LNS increased folate (with HAART: +17%, P = 0.037; without HAART: +39%, P < 0.001) and decreased TfR concentrations (with HAART only: −12%, P = 0.023). HAART was associated with lower vitamin B-12 concentrations only when LNS was present (−18%, P = 0.001), whereas LNS increased vitamin B-12 only when no HAART was present (+27%, P < 0.001). HAART, but not LNS, was associated with higher retinol-binding protein (RBP; +10%, P = 0.007). We detected no association of HAART or LNS with selenium, ferritin, or hemoglobin. Conclusion: The association of HAART with lower folate, iron

HIV-infected children are at an increased risk of developing cancer. Many of the cancers in HIV-infected children are linked to immunosuppression and oncogenic coinfections. Worldwide most HIV-infected children live in sub-Saharan Africa, but cancer data for this population are scarce. In this article, we review the current literature on the epidemiology and prevention of cancer in HIV-infected children. Combined antiretroviral therapy (cART) reduces the risk of developing cancer in HIV-infected children. Cancer risk remains increased in children who start cART at older ages or more advanced immunosuppression as compared with children who start cART at younger age and with mild immunosuppression. Starting cART before severe immunosuppression develops is key to prevent cancer in HIV-infected children but most children in low-income countries start cART at severe immunosuppression levels. Vaccination against high-risk variants of human papillomavirus may protect again human papillomavirus-associated cancer later in life. However, tailoring of human papillomavirus vaccination guidelines for HIV-infected children and young women awaits answers to determine the best vaccination strategies. Better data on the short-term and long-term risks of developing cancer and the effects of preventive measures in HIV-infected children from regions with high burden of HIV/AIDS are urgently needed.

By the year 2000 there will be six million pregnant women and five to ten million children infected with HIV-1. Intervention strategies have been planned and in some instances already started. A timely and cost-effective strategy needs to take into account that most HIV-1 infected individuals reside in developing countries. Further studies are needed on immunological and virological factors affecting HIV-1 transmission from mother to child, on differential disease progression in affected children, and on transient infection.

We tested the plasma of 51 HIV-1-infected children (23 naïve and 28 ART treated) for neutralization against five primary isolates (PIs) generated from adult Indian HIV-1-infected patients. The plasma exhibited neutralization potential with significantly higher neutralizing antibody titers in ART-treated children than naïve children against three out of five PIs (p<0.0001). Further, in treated children, neutralizing antibody titers were higher in those children with suppressed viremia (<1000 RNA copies/mL) than non-suppressors against two of the three PIs. We report here for the first time the neutralization potential of the plasma of HIV-1-infected Indian children.

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. Among 610 HIV-infected children in three studies

Intestinal protozoa are common opportunistic infections in HIV patients. Longitudinal studies on either the clinical relevance, or the effect of immune reconstitution by anti-retroviral therapy on intestinal protozoan infections are children is lacking however. This study investigates prevalence and clinical relevance of intestinal protozoa in HIV-infected Malawian children prior to and during their first year of ART. Stool samples collected at enrolment and during follow-up were tested for non-opportunistic (Giardia lamblia, Dientamoeba fragilis, Entamoeba histolytica) and opportunistic protozoa (Entroctytoon bieneusi, Encephalitozoon spp., Cryptosporidium spp and Cystoisospora belli) using multiplex real-time Polymerase Chain Reaction (PCR). Associations between infections and clinical symptoms were evaluated using univariate methods. Non-opportunistic and opportunistic protozoa were detected in 40%(14/35) and 46%(16/35) of children at baseline respectively. E. bieneusi was the most prevalent protozoa (37%, 13/35) and associated with gastrointestinal complaints(43% in positive (10/13) versus 18% (4/22) in E. bieneusi-negative children, p=0.001). Body Mass Index (BMI) recovery during 12 months of ART was more commonly delayed in E. bieneusi-positive (+0.29+SD 0.83) than E. bieneusi-negative children (+1.03+SD 1.25; p=0.05). E. bieneusi was not detected after 12 months of ART. E. bieneusi was the most prevalent opportunistic intestinal protozoa, present in over a third of study participants prior to initiation of ART. Although all children cleared E.bieneusi after 12 months of ART, E. bieneusi was associated with gastro-intestinal complaints and may delay BMI recovery. Trials to assess effect of treatment of E. bieneusi on nutritional status should be considered in HIV-infected African children.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial License 4.0 (CCBY-NC), where it is permissible to download

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. 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. Routine, systematic, and comprehensive cardiac evaluation, including a thorough history and directed laboratory assays, is essential for the care of HIV-infected adults and

To evaluate the clinical, nutritional and neurodevelopment status of HIV-infected children in a high HIV prevalence area. All HIV-infected children under 15 years of age attending an outpatient clinic of Mozambique between April and May 2010 were recruited. Clinical data were collected and physical examination was performed. In all, 140 children were recruited. The median age at HIV diagnosis was 2.1 years. Fifty-one percent of the children were classified in WHO clinical Stages 3 or 4. Median age of antiretroviral treatment commencement was 3.9 years. Overall, 68% were undernourished, mainly stunted. Forty-four percent failed to pass the national psychomotor developmental test. The pathways for early HIV diagnosis and start of antiretrovirals in children should be improved in Mozambique. Malnutrition, especially stunting, and developmental delay were highly prevalent. Further research focused on early diagnosis of neurocognitive disorders and on the indications of antiretroviral treatment commencement based on chronic malnutrition is required. © The Author [2015].

Although varicella vaccine is given to clinically stable human immunodeficiency virus (HIV)-infected children, its effectiveness is unknown. We assessed its effectiveness by reviewing the medical records of closely monitored HIV-infected children, including those receiving highly active antiretroviral therapy (HAART) between 1989 and 2007. Varicella immunization and development of varicella or herpes zoster were noted. Effectiveness was calculated by subtracting from 1 the rate ratios for the incidence rates of varicella or herpes zoster in vaccinated versus unvaccinated children. The effectiveness of the vaccine was 82% (95% confidence interval [CI], 24%-99%; P = .01) against varicella and was 100% (95% CI, 67%-100%; P < .001) against herpes zoster. When the analysis was controlled for receipt of HAART, vaccination remained highly protective against herpes zoster.

Abstract Pediatric human immunodeficiency virus (HIV) infection and malnutrition are still 2 major health issues in sub-Saharan Africa including Burkina Faso where few studies have been conducted on child malnutrition and HIV infection. This study assessed the effects of antiretroviral therapy (ART) in HIV infection and also compared the prevalence of malnutrition in terms of an inadequate diet, underweight, stunting, and wasting among HIV-infected and uninfected children less than 5 years in Bobo-Dioulasso city, Burkina Faso. This was a case–control study matching for age and sex in 164 HIV-infected and 164 HIV-uninfected children. The sociodemographic characteristics of mothers and children, household food security, drinking water source, child feeding and care practices, and child anthropometric data such as body weight, height, and mid-upper arm circumference were collected. The prevalence of food insecurity and inadequate diet was 58% and 92% of children less than 5 years of age, respectively. The prevalence of underweight, stunting, and wasting was 77% versus 35%, 65% versus 61%, and 63% versus 26% in HIV-infected and uninfected children less than 5 years of age, respectively. Out of 164 HIV-infected children, 59% were on ART initiation during data collection and the median of CD4 cell counts was 1078 cells/μL. HIV-infected children on ART had greater CD4 cell counts (P = .04) and higher weight-for-age Z (P = .01) and weight-for-height Z scores (P = .03) than those without ART. HIV infection was a risk factor for those who had inadequate dietary intake [adjusted odds ratio (AOR) = 2.17, 95% confidence interval (CI) 1.17–3.62, P = .04]. In addition, HIV-infected children were more likely of being underweight (AOR = 10.24, 95% CI 4.34–24.17, P < 0.001) and wasting (AOR = 5.57, 95% CI 2.49–12.46, P < 0.001) than HIV-uninfected children less than 5 years of age.

Humoral immune responses in human immunodeficiency virus (HIV)-infected and uninfected children with Pneumocystis pneumonia (PcP) are poorly understood. Consecutive children hospitalized with acute pneumonia, tachypnea, and hypoxia in South Africa were investigated for PcP, which was diagnosed by real-time polymerase chain reaction on lower respiratory tract specimens. Serum antibody responses to recombinant fragments of the carboxyl terminus of Pneumocystis jirovecii major surface glycoprotein (MsgC) were analyzed. 149 children were enrolled of whom 96 (64%) were HIV-infected. PcP occurred in 69 (72%) of HIV-infected and 14 (26%) of HIV-uninfected children. HIV-infected children with PcP had significantly decreased IgG antibodies to MsgC compared to HIV-infected patients without PcP, but had similar IgM antibodies. In contrast, HIV-uninfected children with PcP showed no change in IgG antibodies to MsgC, but had significantly increased IgM antibodies compared to HIV-uninfected children without PCP. Age was an independent predictor of high IgG antibodies, whereas PcP was a predictor of low IgG antibodies and high IgM antibodies. IgG and IgM antibody levels to the most closely related MsgC fragments were predictors of survival from PcP. Young HIV-infected children with PcP have significantly impaired humoral immune responses to MsgC, whereas HIV-uninfected children with PcP can develop active humoral immune responses. The children also exhibit a complex relationship between specific host factors and antibody levels to MsgC fragments that may be related to survival from PcP.

Background HIV and anaemia are major health challenges in Africa. Anaemia in HIV-infected individuals is associated with more rapid disease progression and a poorer prognosis if not addressed appropriately. This study aimed at determining the severity and types of anaemia among HIV infected children and its effect on short term response to antiretroviral therapy (ART). Methods At baseline, clinical and haematological parameters of 257 HIV-infected ART-naïve children aged 3 months to 18 years were assessed to determine the prevalence, severity and types of anaemia. ART eligible patients were started on therapy according to WHO criteria, enrolled (n=88) into an observational cohort and followed up for 6 months. Results Anaemia was present in 148/257 (57.6%) of children, including (93/148) 62.2% with mild anaemia, 47/148 (32.0%) moderate anaemia, and 7/148 (4.8%) with severe anaemia. The mean haemoglobin (hb) was lower among children with more advanced HIV disease (p<0.0001). Microcytic-hypochromic anaemia (44.9%) was the commonest type of anaemia. Anaemia was independently associated with young age (p <0.0001), advanced HIV WHO disease stage (p = 0.034) and low CD4 percentage (p = 0.048). The proportion of children who had attained viral suppression (viral load <400 copies/ml) at 3 months was significantly lower among the anaemic children, 31/58 (53.4%) compared to the non-anaemic children 26/30 (86.7%) (p=0.002). However, the difference in clinical and immunological response between the anaemic and non-anaemic patients did not reach statistical significance. Conclusion Anaemia is highly prevalent among HIV-infected children in a rural Ugandan clinic and is associated with poorer virological suppression. However, the anaemia did not impact clinical and immunological response to ART among these children. PMID:23114115

The effect of mother's HIV-status on child vaccination is an important public health issue in countries with high HIV prevalence. We conducted a study in a primary healthcare center located in Niamey, the capital of Niger, which offers free of charge services to HIV positive and/or underprivileged mothers, with the aim of assessing: 1) vaccination coverage for children 0-36 months old, born to HIV-infected mothers, and 2) the impact of maternal HIV status on child vaccination. Mothers of children less than 36 months old attending the center were interviewed, to collect information on vaccines administered to their child, and family's socio-demographic characteristics. Overall, 502 children were investigated. Children of HIV-seropositive mothers were less likely to receive follow up vaccinations for Diphtheria-Tetanus-Pertussis (DTP) than those of HIV-seronegative mothers, with a prevalence ratio (PR) of 2.03 (95%CI: 1.58-2.61). Children born to HIV-seropositive mothers were less likely to miss vaccination for MMR than those born to HIV negative mothers, with a RR of 0.46 (95%CI: 0.30-0.72). Vaccine coverage among children born to HIV infected mothers was rather low. It is important to favor access to vaccination programs in this population.

To assess the prevalence of dyslipidemia and lipodystrophy in Indian children receiving non-nucleoside reverse transcriptase inhibitor (NNRTI) based highly active antiretroviral therapy (HAART) and to determine the associated risk factors for the same. The present cross-sectional study was conducted at a Pediatric Clinic of a tertiary care teaching center in India, from May 2011 through December 2012. HIV infected children aged 5-15 y were enrolled if they did not have any severe disease or hospital admission within last 3 mo or receive any medications known to affect the lipid profile. Eighty-one children were on highly active antiretroviral therapy (HAART) for at least 6 mo and 16 were receiving no antiretroviral therapy (ART). Participants' sociodemographic, nutritional, clinical, and laboratory data were recorded in addition to anthropometry and evidence of lipodystrophy. Fasting lipid profile, apolipoprotein A1 and B levels were done for all the children. Among the children on highly active antiretroviral therapy (HAART), 38.3 % had dyslipidemia and 80.2 % had lipodystrophy, while 25 % antiretroviral therapy (ART) naïve HIV infected children had dyslipidemia. No clinically significant risk factors could be identified that increased the risk of dyslipidemia or lipodystrophy in children on highly active antiretroviral therapy (HAART). There is a high prevalence of dyslipidemia and lipodystrophy in Indian children with HIV infection with an imminent need to establish facilities for testing and treatment of these children for metabolic abnormalities.

Objectives Nucleoside reverse transcriptase inhibitors (NRTIs) used in HIV antiretroviral therapy can inhibit human telomerase reverse transcriptase. We therefore investigated whether in utero or childhood exposure to NRTIs affects leukocyte telomere length (LTL), a marker of cellular aging. Methods In this cross-sectional CARMA cohort study, we investigated factors associated with LTL in HIV -1-infected (HIV+) children (n = 94), HIV-1-exposed uninfected (HEU) children who were exposed to antiretroviral therapy (ART) perinatally (n = 177), and HIV-unexposed uninfected (HIV−) control children (n = 104) aged 0–19 years. Univariate followed by multivariate linear regression models were used to examine relationships of explanatory variables with LTL for: a) all subjects, b) HIV+/HEU children only, and c) HIV+ children only. Results After adjusting for age and gender, there was no difference in LTL between the 3 groups, when considering children of all ages together. In multivariate models, older age and male gender were associated with shorter LTL. For the HIV+ group alone, having a detectable HIV viral load was also strongly associated with shorter LTL (p = 0.007). Conclusions In this large study, group rates of LTL attrition were similar for HIV+, HEU and HIV− children. No associations between children’s LTL and their perinatal ART exposure or HIV status were seen in linear regression models. However, the association between having a detectable HIV viral load and shorter LTL suggests that uncontrolled HIV viremia rather than duration of ART exposure may be associated with acceleration of blood telomere attrition.

This study aimed to investigate the demographic profiles of human immunodifficiency virus (HIV) infected anti-retroviral therapy (ART) naïve children in our hospital and their relations to the clinical, immunological and nutritional status. A cross-sectional study was conducted in an Integrated Counselling and Testing Center (ICTC) at a tertiary care hospital in Mumbai. ART naïve HIV positive children were enrolled in the study. The demographic profiles, clinical features, immunological (CD4%/CD4 count) and nutritional status of these children were recorded. The agreement between clinical, immunological and nutritional staging was determined using Cohen's kappa test. In 192 HIV-infected ART naive children enrolled with a median age of 9 years (range 3 months-14 years), 97.4% acquired infection through vertical transmission. The most common clinical presentation was fever (39.6 %), followed by generalized lymphadenopathy (32.3%), cough (22.4%) and diarrhoea (9.9%). Tuberculosis was seen in 22.9% of the children. The agreement was fair between clinical and immunological staging, and slight between nutritional, immunological and clinical staging. Perinatal transmission is the most common mode of acquiring HIV infection in children. The Prevention of Parent to Child Transmission (PPTCT) program should be strengthened for lowering the transmission rate by providing extended ART to mothers during pregnancy and breast-feeding. Tuberculosis remains a major concern in HIV-infected children. The poor correlation between WHO clinical and immunological staging emphasizes the importance of making CD4 facilities available in HIV prevalent areas. Malnutrition cannot be used as a surrogate marker for predicting stage or severity as it is common at all stages of HIV disease.

There is paucity of data describing the risk factors for anaemia among HIV infected children in Tanzania. This cross sectional study aimed at determining the contributing factors for anaemia among HIV-infected children attending Muhimbili National Hospital in Dar es Salaam. Both univariate and multivariate logistic regression analyses were performed to identify possible factors associated with anaemia in HIV-infected children. In this study a total of 75 (44%) patients among 167 recruited HIV children aged 6 months to 59 months were found to be anaemic (Hg<11 g/dl). Multivariate logistic regression demonstrated that not being on HAART (OR 3.40, 95%CI (1.20-9.60), having CD4% <25% (OR 2.30, 95%CI (1.20-34.60), having a history of tuberculosis (TB) (OR 3.23, 95%CI (1.10-9.70) and having hookworm infestation (OR 5.97, 95%CI (1.92-18.4) were independent risk factors for anaemia among HIV infected children. The analyses also showed that being HIV positive for ≥ 2.5 years resulted into a low risk of severe anaemia compared to being HIV positive for < 2.5 years. Taking multivitamins (OR 0.07, 95%, CI (0.020-0.30) and antihelminthics (OR 0.27, 95%CI (0.10-0.74) were also protective against anaemia in children. Similar factors (with exception of using antihelmintics) were associated with severe anaemia. In conclusion the factors associated with anaemia in HIV infected children were multifactorial in nature. Efforts to correct anaemia in HIV infected children should include use of HAART and treatment of infections such as TB and hookworms.

Background Humoral immune responses in human immunodeficiency virus (HIV)-infected and uninfected children with Pneumocystis pneumonia (PcP) are poorly understood. Methods Consecutive children hospitalized with acute pneumonia, tachypnea, and hypoxia in South Africa were investigated for PcP, which was diagnosed by real-time polymerase chain reaction on lower respiratory tract specimens. Serum antibody responses to recombinant fragments of the carboxyl terminus of Pneumocystis jirovecii major surface glycoprotein (MsgC) were analyzed. Results 149 children were enrolled of whom 96 (64%) were HIV-infected. PcP occurred in 69 (72%) of HIV-infected and 14 (26%) of HIV-uninfected children. HIV-infected children with PcP had significantly decreased IgG antibodies to MsgC compared to HIV-infected patients without PcP, but had similar IgM antibodies. In contrast, HIV-uninfected children with PcP showed no change in IgG antibodies to MsgC, but had significantly increased IgM antibodies compared to HIV-uninfected children without PCP. Age was an independent predictor of high IgG antibodies, whereas PcP was a predictor of low IgG antibodies and high IgM antibodies. IgG and IgM antibody levels to the most closely related MsgC fragments were predictors of survival from PcP. Conclusions Young HIV-infected children with PcP have significantly impaired humoral immune responses to MsgC, whereas HIV-uninfected children with PcP can develop active humoral immune responses. The children also exhibit a complex relationship between specific host factors and antibody levels to MsgC fragments that may be related to survival from PcP. PMID:24386119

In this study, we sought to evaluate the influence of sociodemographic factors, ie, age, sex, socioeconomic status, maternal education, and human immunodeficiency virus (HIV) status, on cognitive performance in school-aged HIV-infected Nigerian children. Sixty-nine HIV-positive children aged 6-15 years were matched with 69 HIV-negative control children for age and sex. The children were subdivided for the purpose of analysis into two cognitive developmental stages using Piaget's staging, ie, the concrete operational stage (6-11 years) and the formal operational stage (12-15 years). All participants underwent cognitive assessment using Raven's Standard Progressive Matrices (RPM). Sociodemographic data for the study participants, ie, age, sex, socioeconomic status, and level of maternal education, were obtained using a study proforma. Logistic regression analyses were used to determine associations of HIV status and sociodemographic characteristics with RPM cognitive scores. The overall mean RPM score for the HIV-positive children was 18.2 ± 9.8 (range 8.0-47.0) which was significantly lower than the score of 27.2 ± 13.8 (range 8.0-52.0) for the HIV-negative children (P < 0.001). On RPM grading, 56.5% of the HIV-positive children had cognitive performance at below average to intellectually defective range. Below average RPM scores were found to be significantly associated with younger age (6-11 years), positive HIV status, lower socioeconomic status, and low level of maternal education. Younger age, poor socioeconomic status, and low level of maternal education were factors apart from HIV infection that were significantly associated with low cognitive function in school-aged HIV-infected Nigerian children.

Research shows, conclusively, that perinatal HIV infection has negative effects on cognitive functioning of children and adolescents. However, the extent of these cognitive impairments is unknown. Current literature does not document specific cognitive domains most affected in HIV-infected children and adolescents. To systematically review and meta-analyze the degree of cognitive impairment, and the specific cognitive domains affected, in children and adolescents with perinatally acquired HIV infection. We systematically searched 5 electronic bibliographic databases, namely: PubMed, PsychINFO, Academic Search Premier, Scopus, and WorldCat, by using a search protocol specifically designed for this study. Studies were selected on the basis of set a priori eligibility criteria. Titles, abstracts, and full texts were assessed by 2 independent reviewers. Data from included studies were extracted into Microsoft Excel by 2 independent reviewers. Twenty-two studies were identified for inclusion in the systematic review and of this, 6 studies were included in the meta-analysis. Results from the meta-analysis indicated that working memory and executive function were the domains most affected by the HIV virus. Only 27% of the included studies were suitable to enter into the meta-analysis. There was significant geographic bias in published studies, with only 32% (7/22) of included studies from sub-Saharan Africa. The evidence supports an association between HIV infection in children and adolescents and cognitive impairment in the domains of working memory, executive function and processing speed, with effect size estimates also providing some support for deficits in visual memory and visual-spatial ability.

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

The Wechsler Intelligence Scale for Children - Third Edition UK test was administered to groups of children between the ages of 6 and 12 years with vertically transmitted HIV infection (n = 70) and a control group who were not infected by the virus (n = 70). The study was conducted in India. The two groups were matched for general verbal abilities, age and gender. The children were assessed for Verbal IQ, Performance IQ and Full-Scale IQ. The Verbal Comprehension Index, Perceptual Organization Index and Freedom from Distractibility Index were also obtained. A three-factor analysis of variance disclosed that school-age children with vertically transmitted HIV infection notched below in the areas of Verbal IQ, Performance IQ, Full-Scale IQ, Verbal Comprehension Index, Perceptual Organization Index and Freedom from Distractibility Index when collated with normal uninfected cohorts. Findings are discussed in the light of both theoretical and clinical implications. © The Author(s) 2015.

Data on pediatric HIV in Peru are limited. The National Institute of Child Health (Instituto Nacional de Salud del Niño: INSN) cares for the most HIV-infected children under the age of 18 years in the country. We describe the outcomes of children seen at INSN's HIV clinic over the 10 years when antiretroviral therapy and prevention of mother-to-child transmission (PMTCT) interventions became available in 2004. We conducted a retrospective review of INSN HIV clinic patients between 2003 and 2012. Deidentified data were collected and analyzed. A total of 280 children were included: 50.0% (140/280) were male; 80.0% (224/280) lived in metropolitan Lima. Perinatal transmission was the mode of HIV infection in 91.4% (256/280) of children. Only 17% (32/191) of mothers were known to be HIV-infected at delivery; of these mothers, 41% (13/32) were receiving antiretroviral therapy at delivery, 72% (23/32) delivered by Cesarean section and 47% (15/32) of their infants received antiretroviral prophylaxis. Median age at HIV diagnosis for all children was 35.7 months (interquartile range 14.5-76.8 months), and 67% (143/213) had advanced disease (clinical stage C). After HIV diagnosis, the most frequent hospitalization discharge diagnoses were bacterial pneumonia, chronic malnutrition, diarrhea, anemia and tuberculosis. Twenty-four patients (8.6%) died at a median age of 77.4 months. Most cases of pediatric HIV were acquired via perinatal transmission; few mothers were diagnosed before delivery; and among mothers with known HIV status, PMTCT was suboptimal even after national PMTCT policy was implemented. Most children were diagnosed with advanced disease. These findings underscore the need for improving early pediatric HIV diagnosis and treatment, as well as PMTCT strategies.

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

Although HIV infection is associated with well-known oral pathologies, there remains a dearth of comparative studies aimed at determining the association between HIV infection/exposure and early childhood caries. This is a cross-sectional study using a convenience sample of 3 groups of children receiving care at a tertiary care hospital in Nigeria. The groups include HIV infected (HI), HIV exposed but uninfected and HIV-unexposed and -uninfected children 6 through 72 months of age. Medical records were reviewed, and caregivers were interviewed for sociodemographic, maternal and birth factors as well as early feeding and dietary information. Oral examinations were performed by trained dentist examiners. Of 335 children enrolled, 33 (9.9%) presented with caries. In an adjusted analysis, compared with HIV-unexposed and -uninfected children, HI children had significantly greater odds of having caries (odds ratio = 2.58; 95% confidence interval: 1.04-6.40; P = 0.04), but there was no statistically significant difference in HIV exposed but uninfected children (odds ratio = 2.01; 95% confidence interval: 0.56-7.23; P = 0.28). Factors significantly associated with higher caries prevalence include low CD4 counts and percentage, older age, longer duration of breastfeeding and spontaneous membrane rupture during delivery. Caries was more prevalent in HI children. These findings support the need to target HI children for oral health prevention and treatment services particularly in Nigeria and other developing countries.

This observational study aimed to describe immunopathogenesis and treatment outcomes in children with and without severe acute malnutrition (SAM) and HIV-infection. We studied markers of microbial translocation (16sDNA), intestinal damage (iFABP), monocyte activation (sCD14), T-cell activation (CD38, HLA-DR) and immune exhaustion (PD1) in 32 HIV-infected children with and 41 HIV-infected children without SAM prior to initiation of antiretroviral therapy (ART) and cross-sectionally compared these children to 15 HIV-uninfected children with and 19 HIV-uninfected children without SAM. We then prospectively measured these markers and correlated them to treatment outcomes in the HIV-infected children at 48 weeks following initiation of ART. Plasma levels of 16sDNA, iFABP and sCD14 were measured by quantitative real time PCR, ELISA and Luminex, respectively. T cell phenotype markers were measured by flow cytometry. Multiple regression analysis was performed using generalized linear models (GLMs) and the least absolute shrinkage and selection operator (LASSO) approach for variable selection. Microbial translocation, T cell activation and exhaustion were increased in HIV-uninfected children with SAM compared to HIV-uninfected children without SAM. In HIV-infected children microbial translocation, immune activation, and exhaustion was strongly increased but did not differ by SAM-status. SAM was associated with increased mortality rates early after ART initiation. Malnutrition, age, microbial translocation, monocyte, and CD8 T cell activation were independently associated with decreased rates of CD4% immune recovery after 48 weeks of ART. SAM is associated with increased microbial translocation, immune activation, and immune exhaustion in HIV-uninfected children and with worse prognosis and impaired immune recovery in HIV-infected children on ART.

Abstract This observational study aimed to describe immunopathogenesis and treatment outcomes in children with and without severe acute malnutrition (SAM) and HIV-infection. We studied markers of microbial translocation (16sDNA), intestinal damage (iFABP), monocyte activation (sCD14), T-cell activation (CD38, HLA-DR) and immune exhaustion (PD1) in 32 HIV-infected children with and 41 HIV-infected children without SAM prior to initiation of antiretroviral therapy (ART) and cross-sectionally compared these children to 15 HIV-uninfected children with and 19 HIV-uninfected children without SAM. We then prospectively measured these markers and correlated them to treatment outcomes in the HIV-infected children at 48 weeks following initiation of ART. Plasma levels of 16sDNA, iFABP and sCD14 were measured by quantitative real time PCR, ELISA and Luminex, respectively. T cell phenotype markers were measured by flow cytometry. Multiple regression analysis was performed using generalized linear models (GLMs) and the least absolute shrinkage and selection operator (LASSO) approach for variable selection. Microbial translocation, T cell activation and exhaustion were increased in HIV-uninfected children with SAM compared to HIV-uninfected children without SAM. In HIV-infected children microbial translocation, immune activation, and exhaustion was strongly increased but did not differ by SAM-status. SAM was associated with increased mortality rates early after ART initiation. Malnutrition, age, microbial translocation, monocyte, and CD8 T cell activation were independently associated with decreased rates of CD4% immune recovery after 48 weeks of ART. SAM is associated with increased microbial translocation, immune activation, and immune exhaustion in HIV-uninfected children and with worse prognosis and impaired immune recovery in HIV-infected children on ART.

Antiretroviral treatment means many HIV infected children are surviving with a highly stigmatised condition. There is a paucity of data to inform policies for this growing cohort. Hence we carried out a study on the health, schooling, needs, aspirations, perspectives and knowledge of HIV infected and affected children in Botswana. A cross-sectional survey using interviews and focus group discussions among HIV infected children aged 6-18 years versus HIV aged matched HIV uninfected counterparts living in the same households between August 2010 and March 2011. Supplemental clinical data was abstracted from medical records for HIV infected participants. Nine hundred eighty-four HIV infected and 258 affected children completed the survey. Females predominated in the affected group (63.6 % versus 50.3 %, P < 0.001). School attendance was high in both groups (98.9 % versus 97.3 %, P = 0.057). HIV infected children were mostly in primary school (grades 3-7) while affected children were mostly in upper primary or secondary grades. Sixty percent HIV infected children reported having missed school at least 1 day in the preceding month. Significantly more infected than affected children reported experiencing problems at school (78 % versus 62.3 %, P < 0.001). Twenty-two percent of 15-18 year old HIV infected children were in standard seven and below compared to only 8 % of HIV affected children (p = 0.335). School related problems included poor grades, poor health/school attendance, stigma and inadequate scholastic materials. The wish-list for improving the school environment was similar for both groups and included extra learning support; better meals; protection from bullying/teasing; more scholastic materials, extracurricular activities, love and care; structural improvements; improved teacher attendance and teaching approaches. Significantly more HIV infected children reported feeling hungry all the time (50.6 % versus 41 %, P = 0.007) and

Background The Expanded Program on Immunization (EPI) is the most cost-effective measures to control vaccine-preventable diseases. Currently, the EPI schedule is similar for HIV-infected children; the introduction of antiretroviral therapy (ART) should considerably prolong their life expectancy. Methods and Principal Findings To evaluate the persistence of antibodies to the EPI vaccines in HIV-infected and HIV-exposed uninfected children who previously received these vaccines in routine clinical practice, we conducted a cross-sectional study of children, aged 18 to 36 months, born to HIV-infected mothers and living in Central Africa. We tested blood samples for antibodies to the combined diphtheria, tetanus, and whole-cell pertussis (DTwP), the measles and the oral polio (OPV) vaccines. We enrolled 51 HIV-infected children of whom 33 were receiving ART, and 78 HIV-uninfected children born to HIV-infected women. A lower proportion of HIV-infected children than uninfected children had antibodies to the tested antigens with the exception of the OPV types 1 and 2. This difference was substantial for the measles vaccine (20% of the HIV-infected children and 56% of the HIV-exposed uninfected children, p<0.0001). We observed a high risk of low antibody levels for all EPI vaccines, except OPV types 1 and 2, in HIV-infected children with severe immunodeficiency (CD4+ T cells <25%). Conclusions and Significance Children were examined at a time when their antibody concentrations to EPI vaccines would have still not undergone significant decay. However, we showed that the antibody concentrations were lowered in HIV-infected children. Moreover, antibody concentration after a single dose of the measles vaccine was substantially lower than expected, particularly low in HIV-infected children with low CD4+ T cell counts. This study supports the need for a second dose of the measles vaccine and for a booster dose of the DTwP and OPV vaccines to maintain the antibody concentrations

Background: Associations between abnormal body fat distribution and clinical variables are poorly understood in pediatric HIV disease. Objective: Our objective was to compare total body fat and its distribution in perinatally HIV-infected and HIV-exposed but uninfected (HEU) children and to evaluate associations with clinical variables. Design: In a cross-sectional analysis, children aged 7–16 y in the Pediatric HIV/AIDS Cohort Study underwent regionalized measurements of body fat via anthropometric methods and dual-energy X-ray absorptiometry. Multiple linear regression was used to evaluate body fat by HIV, with adjustment for age, Tanner stage, race, sex, and correlates of body fat in HIV-infected children. Percentage total body fat was compared with NHANES data. Results: Males accounted for 47% of the 369 HIV-infected and 51% of the 176 HEU children. Compared with HEU children, HIV-infected children were older, were more frequently non-Hispanic black, more frequently had Tanner stage ≥3, and had lower mean height (−0.32 compared with 0.29), weight (0.13 compared with 0.70), and BMI (0.33 compared with 0.63) z scores. On average, HIV-infected children had a 5% lower percentage total body fat (TotF), a 2.8% lower percentage extremity fat (EF), a 1.4% higher percentage trunk fat (TF), and a 10% higher trunk-to-extremity fat ratio (TEFR) than did the HEU children and a lower TotF compared with NHANES data. Stavudine use was associated with lower EF and higher TF and TEFR. Non-nucleotide reverse transcriptase inhibitor use was associated with higher TotF and EF and lower TEFR. Conclusion: Although BMI and total body fat were significantly lower in the HIV-infected children than in the HEU children, body fat distribution in the HIV-infected children followed a pattern associated with cardiovascular disease risk and possibly related to specific antiretroviral drugs.

To determine frequency of HIV in children with disseminated tuberculosis and tuberculous meningitis in a low HIV prevalence area, and to study clinical profile of those found HIV positive. Cross-sectional, descriptive study. Jawaharlal Nehru Medical College, Aligarh Muslim University, Aligarh, India from February 2005 to January 2008. The study was conducted on 215 children under 14 years of age with either disseminated tuberculosis or tuberculous meningitis. HIV infection was diagnosed in accordance with WHO strategy II. In children younger than 18 months, the strategy (to cut down costs) was to screen first by HIV antibody testing and subject only positive cases to virological tests. Parents of HIV positive children were also tested for HIV and counselled. The clinical profile of HIV positive patients was noted. The frequency of HIV was 5.12%, while that in cases of disseminated tuberculosis was much higher (22%). No case with isolated tuberculous meningitis was HIV positive. The majority (45.45%) of patients with HIV were between 1-5 years of age. The mode of infection in 7 (63.63%) cases was parent to child transmission. Loss of weight, prolonged fever, pallor, hepato-splenomegaly and oral candidiasis were the commonest clinical manifestations among HIV positive patients. Clinically directed selective HIV screening in cases of disseminated tuberculosis can pickup undiagnosed cases of the same in areas with low prevalence of HIV infection.

Academic tertiary referral hospital in Durban, South Africa. To describe the incidence and diagnostic challenges of tuberculosis (TB) in human immunodeficiency virus (HIV) infected children with severe acute malnutrition (SAM). Post-hoc analysis of a randomised controlled trial that enrolled antiretroviral therapy naïve, HIV-infected children with SAM. Trial records and hospital laboratory results were explored for clinical diagnoses and bacteriologically confirmed cases of TB. Negative binomial regression was used to explore associations with confirmed cases of TB, excluding cases where the clinical diagnosis was not supported by microbiological confirmation. Of 82 children enrolled in the study, 21 (25.6%) were diagnosed with TB, with bacteriological confirmation in 8 cases. Sputum sampling (as opposed to gastric washings) was associated with an increased risk of subsequent diagnosis of TB (adjusted relative risk [aRR] 1.134, 95%CI 1.02-1.26). Culture-proven bacterial infection during admission was associated with a reduced risk of TB (aRR 0.856, 95%CI 0.748-0.979), which may reflect false-negative microbiological tests secondary to empiric broad-spectrum antibiotics. TB is common in HIV-infected children with SAM. While microbiological confirmation of the diagnosis is feasible, empiric treatment remains common, possibly influenced by suboptimal testing and false-negative TB diagnostics. Rigorous microbiological TB investigation should be integrated into the programmatic management of HIV and SAM.

The Breastfeeding, Antiretrovirals, and Nutrition Study evaluated the effect of daily consumption of lipid-based nutrient supplements (LNS) by 2121 lactating, HIV-infected mothers on the growth of their exclusively breast-fed, HIV-uninfected infants from 0 to 24 wk. The study had a 2 × 3 factorial design. Malawian mothers with CD4+ ≥250 cells/mm3, hemoglobin ≥70 g/L, and BMI ≥17 kg/m2 were randomized within 36 h of delivery to receive either no LNS or 140 g/d of LNS to meet lactation energy and protein needs, and mother-infant pairs were assigned to maternal antiretroviral drugs (ARV), infant ARV, or no ARV. Sex-stratified, longitudinal, random effects models were used to estimate the effect of the 6 study arms on infant weight, length, and BMI. Logistic regression models were used to calculate the odds of growth faltering [decline in weight-for-age Z-score (WAZ) or length-for-age Z-score (LAZ) >0.67] using the control arm as the reference. Although some differences between study arms emerged with increasing infant age in boys, there were no consistent effects of the maternal supplement across the 3 growth outcomes in longitudinal models. At the ages where differences were observed, the effects on weight and BMI were quite small (≤200 g and ≤0.4 kg/m2) and unlikely to be of clinical importance. Overall, 21 and 34% of infants faltered in WAZ and LAZ, respectively. Maternal supplementation did not reduce the odds of infant weight or length faltering from 0 to 24 wk in any arm. These results indicate that blanket supplementation of HIV-infected lactating women may have little impact on infant growth. PMID:22649265

Disclosure of HIV sero-status to HIV-infected children is associated with reduced risk of death and better adherence to antiretroviral drugs. However, caregivers find it difficult to determine when and how they should disclose the HIV sero-positive status to HIV-infected children. In this study, we assessed the determinants and processes of HIV status disclosure to HIV-infected children aged 4 to 17 years receiving HIV care services at the Baylor College of Medicine Children's Foundation Tanzania, Centre of Excellence (COE) in Mbeya. This was a cross-sectional study conducted among 334 caregivers of HIV positive children attending the Baylor COE in Mbeya, Tanzania. Data were collected using quantitative and qualitative research methods. Quantitative data were collected on socio-demographic characteristics of children and caregivers using an interviewer-administered questionnaire. Data were entered into Epi-Info version 3.5.1 and analyzed using STATA version 10. Univariable and multivariable logistic regression analyses were conducted to obtain odds ratios (OR) and 95% confidence intervals (95% CI) associated with disclosing HIV positive status to HIV-infected children. Qualitative data were collected on the processes used in accomplishing the HIV status disclosure event using case histories and key informant interviews and analyzed manually using latent analysis techniques. About one-third of the caregivers (32.6%) disclosed the children's HIV sero-positive status to them. Disclosure was more likely among children 10 years or older (adjusted OR [AOR] = 8.8; 95% CI: 4.7, 16.5), caregivers with knowledge about HIV disclosure (AOR = 5.7; 95% CI: 2.3, 13.7) and those earning more than Tsh 99,999 (US $62.5) per month (AOR = 2.4; 95% CI: 1.3, 4.5). Qualitative findings showed that caregivers used a diversity of approaches to complete the HIV status disclosure event including direct, third-party, event-driven and use of drawings. Our study shows that disclosure is

The advent of new antiretroviral drugs such as protease inhibitors has generated sensible changes in morbity and mortality in HIV-infected patients. To evaluate the impact of Highly Active Antiretroviral Therapy (HAART) on the prevalence of chronic otitis media in HIV-infected pediatric population. We analyzed medical charts of 471 children aged zero to 12 years and 11 months with HIV infection from an Ambulatory of ENT and AIDS. Children were divided according to the age: 0 to 5 years and 11 months and 6 to 12 years and 11 months and classified as having chronic otitis media based on history, physical examination, audiologic and tympanometric data. Prevalence of chronic otitis media, as well as CD4+ lymphocyte count were compared between groups in use of HAART and the group without HAART. Out of 459 children, 65 (14.2%) had chronic otitis media. We observed that in children aged 0 to 5 years and 11 months who were taking HAART there was significant lower prevalence of chronic otitis media (p=0.02). The use of HAART was associated to higher mean CD4+ lymphocyte count (p<0.001). The use of HAART was associated to reduction in prevalence of chronic otitis media in HIV infected children, probably due to increase in mean CD4+ lymphocyte count.

In 2014, an estimated 2,477 children aged <13 years were living with diagnosed human immunodeficiency virus (HIV) infection in the United States (1). Nationally, little is known about how well children with a diagnosis of HIV infection are retained in medical care. CDC analyzed insurance claims data to evaluate retention in medical care for children in the United States with a diagnosis of HIV infection. Data sources were the 2010-2014 MarketScan Multi-State Medicaid and MarketScan Commercial Claims and Encounters databases. Children aged <13 years with a diagnosis of HIV infection in 2010 were identified using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) diagnostic billing codes for HIV or acquired immunodeficiency syndrome (AIDS), resulting in Medicaid and commercial claims cohorts of 163 and 129 children, respectively. Data for each child were evaluated during a 36-month study period, counted from the date of the first claim containing an ICD-9-CM code for HIV or AIDS. Each child's consistency of medical care was assessed by evaluating the frequency of medical visits during the first 24 months of the study period to see if the frequency of visits met the definition of retention in care. Frequency of medical visits was then assessed during an additional 12-month follow-up period to evaluate differences in medical care consistency between children who were retained or not retained in care during the initial 24-month period. During months 0-24, 60% of the Medicaid cohort and 69% of the commercial claims cohort were retained in care, among whom 93% (Medicaid) and 85% (commercial claims) were in care during months 25-36. To identify areas for additional public health action, further evaluation of the objectives for national medical care for children with diagnosed HIV infection is indicated.

Summary Background Globally, pneumonia is a leading cause of mortality and morbidity in children younger than 5 years. Underlying HIV infection is an important risk factor for pneumonia morbidity and mortality in children. There are, however, no global or country level estimates of pneumonia burden in HIV-infected children. We assessed the role of HIV in pneumonia incidence and mortality and estimated the number of pneumonia cases and deaths in HIV-infected children younger than 5 years in 133 high pneumonia-burden countries in 2010. Methods We estimated the risk of hospital admission and case fatality rate caused by pneumonia in HIV-infected children compared with HIV-uninfected children from a systematic review of studies published in Medline, Embase, and Global Health between Jan 1, 1980, and Aug 31, 2013. We estimated nationwide pneumonia incidence and mortality with two different models that incorporated several risk factors for paediatric pneumonia hospital admission and mortality (including HIV infection). We then estimated the number of pneumonia episodes and deaths that occurred in HIV-infected children in 2010. Findings The odds ratio (OR) for hospital admission for all-cause pneumonia in HIV-infected children compared with HIV-uninfected children was 6·5 (95% CI 5·9–7·2). The risk of death was higher in children with pneumonia and HIV compared with those with pneumonia only (OR 5·9, 95% CI 2·7–12·7). In 2010, 1·4 million pneumonia episodes (uncertainty range [UR] 0·6 million to 3·3 million) and 88 000 pneumonia deaths (UR 47 400–153 000) occurred in HIV-infected children in low-income countries. Of these, 1·2 million pneumonia episodes (UR 0·5 million–2·7 million) and 85 400 deaths (UR 46 000–147 300) were directly attributable to HIV. 1·3 million (90%) pneumonia episodes and 82 400 (93%) pneumonia deaths in HIV-infected children aged younger than 5 years occurred in the WHO African region.

To estimate the prevalence of oral mucosal diseases and dental caries among HIV-infected children receiving antiretroviral treatment (ART) in West Africa and to identify the factors associated with the prevalence of oral mucosal lesions. Multicentre cross-sectional survey in five paediatric HIV clinics in Côte d'Ivoire, Mali and Sénégal. A standardised examination was performed by trained dentists on a random sample of HIV-infected children aged 5-15 years receiving ART. The prevalence of oral and dental lesions and mean number of decayed, missing/extracted and filled teeth (DMFdefT) in temporary and permanent dentition were estimated with their 95% confidence interval (95% CI). We used logistic regression to explore the association between children's characteristics and the prevalence of oral mucosal lesions, expressed as prevalence odds ratio (POR). The median age of the 420 children (47% females) enrolled was 10.4 years [interquartile range (IQR) = 8.3-12.6]. The median duration on ART was 4.6 years (IQR = 2.6-6.2); 84 (20.0%) had CD4 count<350 cells/mm(3). A total of 35 children (8.3%; 95% CI: 6.1-11.1) exhibited 42 oral mucosal lesions (24 were candidiasis); 86.0% (95% CI = 82.6-89.3) of children had DMFdefT ≥ 1. The presence of oral mucosal lesions was independently associated with CD4 count < 350 cells/mm(3) (POR = 2.96, 95% CI = 1.06-4.36) and poor oral hygiene (POR = 2.69, 95% CI = 1.07-6.76). Oral mucosal lesions still occur in HIV-infected African children despite ART, but rarely. However, dental caries were common and severe in this population, reflecting the need to include oral health in the comprehensive care of HIV. © 2014 John Wiley & Sons Ltd.

Unstructured Abstract There are few data on gynaecomastia in HIV-infected children. Within the UK/Ireland’s national cohort, 56/1,873 (3%) HIV-infected children had gynaecomastia, of which 10 (0.5%) were severe. All 10 had received antiretroviral therapy for median 27.5 [21,42] months. 4/10 had received efavirenz, 7/10 and 6/10 stavudine and/or didanosine respectively. Five were non-reversible, despite changing ART, and required breast reduction surgery. PMID:27879556

Little is known about immune activation profiles of children infected with HIV-1 subtype C. The current study compared levels of selected circulating biomarkers of immune activation in HIV-1 subtype C-infected untreated mothers and their children with those of healthy controls. Multiplex bead array, ELISA, and immunonephelometric procedures were used to measure soluble CD14 (sCD14), beta-2 microglobulin (β2M), CRP, MIG, IP-10, and transforming growth factor beta 1 (TGF-β1). Levels of all 6 biomarkers were significantly elevated in the HIV-infected mothers and, with the exception of MIG, in their children (P < 0.01-P < 0.0001). The effects of antiretroviral therapy (ART) and maternal smoking on these biomarkers were also assessed. With the exception of TGF-β1, which was unchanged in the children 12 months after therapy, initiation of ART was accompanied by decreases in the other biomarkers. Regression analysis revealed that although most biomarkers were apparently unaffected by smoking, exposure of children to maternal smoking was associated with a significant increase in IP-10. These findings demonstrate that biomarkers of immune activation are elevated in HIV-infected children pre-ART and decline, with the exception of TGF-β1, after therapy. Although preliminary, elevation of IP-10 in smoke-exposed infants is consistent with a higher level of immune activation in this group.

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. 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. 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). 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.

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

Globally there are about 3.3million children under the age of 15 years living with HIV. Of this number, 88% live in sub-Saharan Africa. In Ghana, an estimated 33,000 children were said to be living with the HIV infection in 2012. Lack of disclosure adversely affects the well-being of the child, including access to paediatric HIV treatment and care and adherence to treatment. However, the greatest psychosocial challenges that parents and caregivers of HIV-infected children face is disclosure of HIV status to their infected children. This study sought to determine the prevalence of and the barriers to the disclosure of HIV status to infected children and adolescents in Lower Manya-Krobo District in Ghana. A cross sectional study with a sample of 118 caregivers of HIV infected children and adolescents aged 4-19 years attending three HIV clinics in the Lower Manya Krobo District, and 10 key informants comprising of healthcare workers and HIV volunteer workers involved in the provision of care to infected children and their families. The prevalence of disclosure was higher. Main barriers to disclosure identified in this study included age of child, perceived cause of HIV, stigma attached to HIV, child's inability to keep diagnosis to self and fear of psychological harm to child. There is the need for the Ghana Health Service in conjunction with the Ghana Aids Commission and the National Aids Control Programme to develop comprehensive context-based disclosure guidelines.

Candidiasis is the most common opportunistic infection seen in human immunodeficiency virus (HIV)-infected individuals. The aim of our study was to estimate the candidiasis rate and evaluate its trend in HIV-infected children in Spain during the era of highly active antiretroviral therapy (HAART) compared to HIV-uninfected children. We carried out a retrospective study. Data were obtained from the records of the Minimum Basic Data Set from hospitals in Spain. All HIV-infected children were under 17 years of age, and a group of HIV-uninfected children with hospital admissions matching the study group by gender and age were randomly selected. The follow-up period (1997-2008) was divided into three calendar periods: a) From 1997 to 1999 for early-period HAART; b) from 2000 to 2002 for mid-period HAART; and c) from 2003 to 2008 for late-period HAART. Among children with hospital admissions, HIV-infected children had much higher values than HIV-uninfected children during each of the three calendar periods for overall candidiasis rates (150.0 versus 6.1 events per 1,000 child hospital admissions/year (p < 0.001), 90.3 versus 3.1 (p < 0.001), and 79.3 versus 10.7 (p < 0.001), respectively) and for non-invasive Candida mycosis (ICM) rates (118.5 versus 3.8 (p < 0.001), 85.3 versus 2.3 (p < 0.001), and 80.6 versus 6.0 (p < 0.001), respectively). In addition, HIV-infected children also had higher values of ICM rates than HIV-uninfected children, except during the last calendar period when no significant difference was found (32.4 versus 1.2 (p < 0.001), 11.6 versus 0.4 (p < 0.001), and 4.6 versus 2.3 (p = 0.387), respectively). For all children living with HIV/AIDS, the overall candidiasis rate (events per 1,000 HIV-infected children/year) decreased from 1997-1999 to 2000-2002 (18.8 to 10.6; p < 0.001) and from 2000-2002 to 2003-2008 (10.6 to 5.7; p = 0.060). Within each category of candidiasis, both non-ICM and ICM rates

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.

Multicultural comparative studies have recently increased scientific knowledge base regarding the mental health of diverse populations. This cross-cultural study was cross-sectionally designed to assess differences in the prevalence and predictors of clinically significant depressive symptoms between Chinese and Malawian children. A total of 478 children (237 Chinese and 241 Malawians) were randomly recruited in the study. The participants completed a Children Depression Inventory in the dimensions of Negative Mood, Interpersonal Problems, Ineffectiveness, Anhedonia, and Negative Self- Esteem. They further provided demographic and family structure information. Data were analyzed by Student's t-test, Chi-square test, and logistic regression. The prevalence of clinically significant depressive symptoms was 16% and 12.4% for Chinese and Malawian study participants, respectively. Multivariate logistic regression analysis showed that fighting among siblings (adjusted odds ratio [aOR] = 4.1, 95% CI, 3.5-5.9), fighting among children and parents (aOR = 7.7, 95% CI, 4.6-9.8) and living with father only (aOR = 4.1, 95% CI, 3.4-6.7) were significant predictors of clinically significant depressive symptoms among Chinese study participants. On the other hand, clinically significant depressive symptoms were predicted by employment status of a mom only among Malawian study participants (aOR = 3.0, 95% CI, 2.3-5.9). We conclude that diverse cultures affect children's mental health differently and this cluster of children has a noticeable amount of depressive symptoms that in the least requires further diagnosis and preventive measures.

To describe the morbidity and mortality associated with tuberculosis (TB) in human immunodeficiency virus (HIV) infected children in Baja California, Mexico. Retrospective review of the medical records of all children with perinatally acquired HIV infection evaluated at Tijuana General Hospital with a diagnosis of TB between 1998 and 2007. The Stegen-Toledo (ST) clinical criteria for the diagnosis of TB were used. A total of 73 HIV-infected children were followed during the study period. Thirteen (18%) children were diagnosed with TB; one was confirmed by culture to be positive. Among these children, the mean ages at HIV and TB diagnosis were respectively 3.6 and 5.3 years. The mean ST score was 8.1; 10/13 had a score of >or=7, or highly probable TB. There were a cumulative 29 hospital admissions prior to TB diagnosis; 24 of these were due to pneumonia. The mean duration of symptoms at TB diagnosis was 73 days. The most common symptoms were cough (92%) and anorexia (85%). Seven patients (54%) had disseminated TB and five (39%) died as a consequence of TB. We observed high morbidity, hospital utilization and high mortality associated with TB among HIV-infected children in Baja California.

Diagnoses of HIV infection among children in the United States have been declining; however, a notable percentage of diagnoses are among those born outside the United States. The impact of foreign birth among children with diagnosed infections has not been examined in the United States. Using the Centers for Disease Control and Prevention National HIV Surveillance System, we analyzed data for children aged <13 years with diagnosed HIV infection ("children") in the United States (reported from 50 states and the District of Columbia) during 2008-2014, by place of birth and selected characteristics. There were 1516 children [726 US born (47.9%) and 676 foreign born (44.6%)]. US-born children accounted for 70.0% in 2008, declining to 32.3% in 2013, and 40.9% in 2014. Foreign-born children have exceeded US-born children in number since 2011. Age at diagnosis was younger for US-born than foreign-born children (0-18 months: 72.6% vs. 9.8%; 5-12 years: 16.9% vs. 60.3%). HIV diagnoses in mothers of US-born children were made more often before pregnancy (49.7% vs. 21.4%), or during pregnancy (16.6% vs. 13.9%), and less often after birth (23.7% vs. 41%). Custodians of US-born children were more often biological parents (71.9% vs. 43.2%) and less likely to be foster or nonrelated adoptive parents (10.4% vs. 55.1%). Of 676 foreign-born children with known place of birth, 65.5% were born in sub-Saharan Africa and 14.3% in Eastern Europe. The top countries of birth were Ethiopia, Ukraine, Uganda, Haiti, and Russia. The increasing number of foreign-born children with diagnosed HIV infection in the United States requires specific considerations for care and treatment.

Background. Children with perinatal human immunodeficiency virus (HIV) infection (PHIV) may not be protected against measles, mumps, and rubella (MMR) because of impaired initial vaccine response or waning immunity. Our objectives were to estimate seroimmunity in PHIV-infected and perinatally HIV-exposed but uninfected (HEU) children and identify predictors of immunity in the PHIV cohort. Methods. PHIV and HEU children were enrolled in the Pediatric HIV/AIDS Cohort Study (PHACS) at ages 7–15 years from 2007 to 2009. At annual visits, demographic, laboratory, immunization, and clinical data were abstracted and serologic specimens collected. Most recent serologic specimen was used to determine measles seroprotection by plaque reduction neutralization assay and rubella seroprotection and mumps seropositivity by enzyme immunoassay. Sustained combination antiretroviral therapy (cART) was defined as taking cART for at least 3 months. Results. Among 428 PHIV and 221 HEU PHACS participants, the prevalence was significantly lower in PHIV children for measles seroprotection (57% [95% confidence interval {CI}, 52%–62%] vs 99% [95% CI, 96%–100%]), rubella seroprotection (65% [95% CI, 60%–70%] vs 98% [95% CI, 95%–100%]), and mumps seropositivity (59% [95% CI, 55%–64%] vs 97% [95% CI, 94%–99%]). On multivariable analysis, greater number of vaccine doses while receiving sustained cART and higher nadir CD4 percentage between last vaccine dose and serologic testing independently improved the cumulative prediction of measles seroprotection in PHIV. Predictors of rubella seroprotection and mumps seropositivity were similar. Conclusions. High proportions of PHIV-infected children, but not HEU children, lack serologic evidence of immunity to MMR, despite documented immunization and current cART. Effective cART before immunization is a strong predictor of current seroimmunity. PMID:26060291

Pediatric human immunodeficiency virus (HIV) infection and malnutrition are still 2 major health issues in sub-Saharan Africa including Burkina Faso where few studies have been conducted on child malnutrition and HIV infection. This study assessed the effects of antiretroviral therapy (ART) in HIV infection and also compared the prevalence of malnutrition in terms of an inadequate diet, underweight, stunting, and wasting among HIV-infected and uninfected children less than 5 years in Bobo-Dioulasso city, Burkina Faso.This was a case-control study matching for age and sex in 164 HIV-infected and 164 HIV-uninfected children. The sociodemographic characteristics of mothers and children, household food security, drinking water source, child feeding and care practices, and child anthropometric data such as body weight, height, and mid-upper arm circumference were collected.The prevalence of food insecurity and inadequate diet was 58% and 92% of children less than 5 years of age, respectively. The prevalence of underweight, stunting, and wasting was 77% versus 35%, 65% versus 61%, and 63% versus 26% in HIV-infected and uninfected children less than 5 years of age, respectively. Out of 164 HIV-infected children, 59% were on ART initiation during data collection and the median of CD4 cell counts was 1078 cells/μL. HIV-infected children on ART had greater CD4 cell counts (P = .04) and higher weight-for-age Z (P = .01) and weight-for-height Z scores (P = .03) than those without ART. HIV infection was a risk factor for those who had inadequate dietary intake [adjusted odds ratio (AOR) = 2.17, 95% confidence interval (CI) 1.17-3.62, P = .04]. In addition, HIV-infected children were more likely of being underweight (AOR = 10.24, 95% CI 4.34-24.17, P < 0.001) and wasting (AOR = 5.57, 95% CI 2.49-12.46, P < 0.001) than HIV-uninfected children less than 5 years of age.High prevalence of malnutrition was observed in HIV-infected children

Human immunodeficiency virus (HIV) is severely affecting the poorly educated and economically disadvantaged in Indian society. When children start developing clinical manifestations, needing treatment, they have to travel long distances for accessing care and support at tertiary institutions. This places an extra burden on patients, who are already struggling to cope with their illness. Sufficient data are needed for the government to evolve appropriate policy for providing care to the children affected with HIV. We undertook this study to present the socio-demographic characteristics, signs and symptoms, clinical profile, distance travelled and follow up pattern of HIV positive children who accessed care for the first time in a referral hospital at Chennai, India. Electronic medical records from patients diagnosed with HIV between 2002 and 2004 at the Government Hospital for Thoracic Medicine (GHTM) in Tambaram (Chennai) in India were analyzed to understand care-seeking behaviours. Demographic variables such as age, sex, education and occupation, data on clinical manifestations were examined together with geographic information. At GHTM 1,768 new paediatric patients accessed care from 2002 to 2004. Children aged less than 5 yr were 49.9 per cent; 1115 children had (63%) tuberculosis. Significantly, 14.9 and 20.6 per cent children had extra-pulmonary TB and disseminated TB respectively. Lower respiratory infection (15.8%), Pneumocystis carinii pneumonia (15.20%), oral/oesophageal candidiasis (13.5%), wasting (6.1%) and diarrhoeal disorders (3.5%) were the common clinical manifestations. In all 47 per cent children traveled between 200-400 km from home and 14 per cent travelled over 400 km. Our findings showed that tuberculosis should be regarded as the indicator disease for HIV infection in children, especially when they have clinical manifestations of progressive, non pulmonary and disseminated disease. The primary and secondary health care centres should have the

Working Memory Profiles in HIV-Exposed, Uninfected and HIV-Infected Children: A Comparison with Neurotypical Controls

2017-01-01

This study compared the working memory profiles of three groups of children, namely HIV-infected (HIV-I; n = 95), HIV-exposed, uninfected (HIV-EU; n = 86) and an HIV-unexposed, uninfected, (HIV-UU; n = 92) neurotypical control group. Working memory, an executive function, plays an important role in frontal lobe-controlled behaviors, such as motivation, planning, decision making, and social interaction, and is a strong predictor of academic success in school children. Memory impairments have been identified in HIV-I children, particularly in visuospatial processing. Verbal working memory has not been commonly investigated in this population, while it is unknown how the working memory profiles of HIV-EU children compare to their HIV-I and HIV-UU peers. Of interest was whether the working memory profiles of the HIV-EU children would be more similar to the HIV-I group or to the uninfected control group. The results revealed no significant differences in working memory performance between the HIV-I and HIV-EU groups. However, this does not mean that the etiology of the working memory deficits is the same in the two groups, as these groups showed important differences when compared to the control group. In comparison to the controls, the HIV-I group experienced difficulties with processing tasks irrespective of whether they drew on a verbal or visuospatial modality. This appears to stem from a generalized executive function deficit that also interferes with working memory. In the HIV-EU group, difficulties occurred with verbally based tasks, irrespective of whether they required storage or processing. For this group, the dual demands of complex processing and using a second language seem to result in demand exceeding capacity on verbal tasks. Both groups experienced the greatest difficulties with verbal processing tasks for these different reasons. Thus, disruption of different cognitive abilities could result in similar working memory profiles, as evidenced in this

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

Little is known regarding waning immunity to tetanus toxoid (TT) in HIV-infected children and the need for booster doses before the recommended interval of 5-10 years. Anti-tetanus antibodies were assessed by ELISA in 24 HIV-infected and 24 control children. A protective level (>0.1 IU/ml) of TT antibodies was observed in 62% of HIV-infected children and in 100% of controls. HIV-infected children with five doses had a significantly (p=0.01) lower prevalence of protective immunity compared to controls. Follow-up anti-TT antibody levels in nine HIV-infected children declined from 1.27 to 0.26 IU/ml, but levels did not decline in the seven controls; five of the seven (71%) children with a non-protective level of antibodies responded with a level>0.16 IU/ml following one booster dose of the vaccine. HIV-infected children may need TT boosters before the recommended 5-10 years. Copyright © 2013 International Society for Infectious Diseases. Published by Elsevier Ltd. All rights reserved.

Introduction Iron deficiency is highly prevalent in pre-school children in developing countries and an important health problem in sub-Saharan Africa. A debate exists on the possible protective effect of iron deficiency against malaria and other infections; yet consensus is lacking due to limited data. Recent studies have focused on the risks of iron supplementation but the effect of an individual's iron status on malaria risk remains unclear. Studies of iron status in areas with a high burden of infections often are exposed to bias. The aim of this study was to assess the predictive value of baseline iron status for malaria risk explicitly taking potential biases into account. Methods and materials We prospectively assessed the relationship between baseline iron deficiency (serum ferritin <30 µg/L) and malaria risk in a cohort of 727 Malawian preschool children during a year of follow-up. Data were analyzed using marginal structural Cox regression models and confounders were selected using causal graph theory. Sensitivity of results to bias resulting from misclassification of iron status by concurrent inflammation and to bias from unmeasured confounding were assessed using modern causal inference methods. Results and Conclusions The overall incidence of malaria parasitemia and clinical malaria was 1.9 (95% CI 1.8–2.0) and 0.7 (95% CI 0.6–0.8) events per person-year, respectively. Children with iron deficiency at baseline had a lower incidence of malaria parasitemia and clinical malaria during a year of follow-up; adjusted hazard ratio's 0.55 (95%-CI:0.41–0.74) and 0.49 (95%-CI:0.33–0.73), respectively. Our results suggest that iron deficiency protects against malaria parasitemia and clinical malaria in young children. Therefore the clinical importance of treating iron deficiency in a pre-school child should be weighed carefully against potential harms. In malaria endemic areas treatment of iron deficiency in children requires sustained prevention of

Growth faltering and micronutrient deficiencies commonly coexist in HIV-exposed children in sub-Saharan Africa, and correcting deficiencies, such as those of vitamins B-complex, C, and E, may improve HIV-related endpoints and child growth. We therefore examined the effect of daily oral supplementation of vitamins B-complex, C, and E on growth among 2341 children born to HIV-infected mothers in Tanzania. HIV-infected women pregnant at ≤32 wk of gestation were enrolled in the study. Children were randomized at age 6 wk to receive multivitamins or placebo until age 104 wk. All women received the same types of vitamins pre- and postnatally. At 6 wk, 256 children (11.1%) were HIV infected and the mean (SD) Z-scores for length for age (LAZ), weight for length (WLZ), and weight for age (WAZ) were -0.39 ± 1.20, -0.21 ± 1.23, and -0.52 ± 1.11, respectively. There was no overall treatment effect on LAZ, WLZ, or WAZ profiles during the follow-up (P ≥ 0.15). There was no treatment effect from 6 to 104 wk on LAZ [(95% CI: -0.14, 0.13); P = 0.94], WLZ [(95% CI: -0.17, 0.13); P = 0.78], or WAZ [(95% CI: -0.15, 0.16); P = 0.97] or on the incidence of growth failure, defined as respective Z-scores < -2 (P ≥ 0.29). Among the subgroup of HIV-uninfected children, there was no treatment effect from 6 to 104 wk on LAZ, WLZ, and WAZ (P ≥ 0.71) or on the incidence of growth failure (P ≥ 0.16). Multivitamin supplements had no effect on growth among children born to HIV-infected women who were themselves receiving multivitamins.

To determine the rate of HIV status disclosure, caregivers' reasons for non-disclosure, and factors influencing disclosure among a sample of HIV-infected children in Enugu, southeast Nigeria. Data were collected prospectively via a questionnaire on HIV-infected children and their caregivers who visited the pediatric HIV clinic of the University of Nigeria Teaching Hospital between July 1, 2012, and June 30, 2013. The data analysis was performed using Statistical Package for the Social Sciences version 19 software. Caregivers of 107 children (age 5-16 years; mean 10.1 ± 3.2 years) were enrolled in the study. There were 53 (49.5%) boys and 54 (50.5%) girls. HIV status had been disclosed to 31 (29%) of them. The major reason for non-disclosure was the child being considered too young. Age (p < .001), age at HIV diagnosis (p < .001) and baseline CD4 count (p = .008) were seen as significant predictors of HIV disclosure. There is a low rate of HIV disclosure to infected children, and it was found to be lower for younger children. We recommend improving efforts for disclosure counseling to caregivers in pediatric HIV clinics.

HIV/AIDS is associated with a wide range of mucocutaneous disorders some of which are useful in the clinical staging and prognosis of the syndrome. There is paucity of information regarding the prevalence and pattern of mucocutaneous disorders among HIV infected children attending paediatric Care and Treatment Centres (CTC) in Dar es Salaam. To determine the prevalence and pattern of mucocutaneous disorders among HIV infected children attending public paediatric 'Care and Treatment Centres' in Dar es Salaam. This was a cross sectional descriptive study involving public paediatric 'Care and Treatment Centres' in Dar es Salaam. Clinical information was obtained using a questionnaire. Dermatological examination was carried out in daylight. Investigations were taken as appropriate. Data was analysed using the Statistical Package for Social Sciences (SPSS) program version 10.0. Chi-squared and Fisher's exact tests were utilized. A p-value of less than 0.05 was considered statistically significant. Three hundred and forty seven HIV infected children (52% males) attending CTCs were recruited into the study. Mucocutaneous disorders were encountered in 85% of them. There was no gender difference in the prevalence of the infective mucocutaneous disorders but males had a higher prevalence of non-infective/inflammatory dermatoses (58%) than females (42%) (p = 0.02). Overall, mucocutaneous disorders (infective + non infective) were more prevalent in advanced stages of HIV disease. Children with advanced HIV disease had a significantly increased frequency of fungal and viral infections (43% and 25% respectively than those with less advanced disease; 24% and 13% respectively (p = 0.01). Seventy four percent of the HIV-infected children with mucocutaneous disorders were already on ART. Mucocutaneous disorders among HIV infected children attending Care and Treatment Centres are common and highly variable. Comprehensive management should also emphasize on the management of

There are few data on gynecomastia in HIV-infected children. Within the UK/Ireland's national cohort, 56 of 1873 (3%) HIV-infected children had gynecomastia, of which 10 (0.5%) were severe. All 10 had received antiretroviral therapy for a median of 27.5 (21, 42) months; 4 of 10 had received efavirenz, 7 of 10 and 6 of 10 had received stavudine and/or didanosine respectively. Five were nonreversible, despite changing antiretroviral therapy, and required breast reduction surgery.

Using routinely collected data, we evaluated a nationally implemented intervention to assist health care workers and caregivers with HIV disclosure to children. We assessed the impact of the intervention on child's knowledge and health outcomes. Data were abstracted from national databases and patient charts for HIV-infected children aged 7-15 years attending 4 high-volume HIV clinics in Namibia. Disclosure rates, time to disclosure, and HIV knowledge in 314 children participating in the intervention were analyzed. Logistic regression was used to identify correlates of partial vs. full disclosure. Paired t-tests and McNemar tests were used to compare adherence and viral load (VL) before versus after intervention enrollment. Among children who participated in the disclosure intervention, 11% knew their HIV status at enrollment and an additional 38% reached full disclosure after enrollment. The average time to full disclosure was 2.5 years (interquartile range: 1.2-3 years). Children who achieved full disclosure were more likely to be older, have lower VLs, and have been enrolled in the intervention longer. Among children who reported incorrect knowledge regarding why they take their medicine, 83% showed improved knowledge after the intervention, defined as knowledge of HIV status or adopting intervention-specific language. On comparing 0-12 months before vs. 12-24 months after enrollment in the intervention, VL decreased by 0.5 log10 copies per milliliter (N = 42, P = 0.004), whereas mean adherence scores increased by 10% (N = 88, P value < 0.001). This HIV disclosure intervention demonstrated improved viral suppression, adherence, and HIV knowledge and should be considered for translation to other settings.

Our objective was to describe the prevalence of low concentrations of retinol, β-carotene, and vitamin E in a group of HIV-infected Latin American children and a comparison group of HIV-exposed, uninfected children. Our hypothesis was that the rates of low concentrations of these micronutrients would be higher in the HIV-infected group than those in the HIV-exposed, uninfected group. This was a cross-sectional substudy of a larger cohort study at clinical pediatric HIV centers in Latin America. Serum levels of micronutrients were measured in the first stored sample obtained after each child’s first birthday by high-performance liquid chromatography. Low concentrations of retinol, β-carotene and vitamin E were defined as serum levels below 0.70 μmol/L, 0.35 μmol/L and 18.0 μmol/L, respectively. The population for this analysis was 336 children (124 HIV-infected, 212 HIV-exposed, uninfected) aged ≥ 1 to < 4 years of age. Rates of low concentrations were 74% for retinol, 27% for β-carotene, and 89% for vitamin E. These rates were not affected by HIV status. Among the HIV-infected children those treated with antiretrovirals were less likely to have retinol deficiency, but no other HIV-related factors correlated with micronutrient low serum levels. Low concentrations of retinol, β-carotene and vitamin E are very common in children exposed to HIV living in Brazil, Argentina and Mexico, regardless of HIV-infection status. PMID:19917451

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

To evaluate the long-term safety and effectiveness of lopinavir/ritonavir (LPV/r) in a population-based cohort of HIV-1-infected children. All children enrolled in the Swiss Mother and Child HIV Cohort Study, treated with LPV/r-based combination antiretroviral treatment (cART) between November 2000 and October 2008, were included. 88 children (25 (28%) protease inhibitor (PI)-naive, 16 (18%) ART-naive) were analysed (251 patient-years on LPV/r). After 48 weeks on LPV/r, 70 children had a median (interquartile range (IQR)) decrease in HIV-1 viral load of 4.25 log (5.45-3.17; PI-naive, n=17) and 2.53 (3.68-1.38; PI-experienced, n=53). Median (IQR) increase in CD4 count was 429 (203-593; PI-naive) and 177 (21-331; PI-experienced) cells/microl. These effects remained stable throughout 192 weeks for 25 children. Treatment was stopped for viral rebound in seven and suspected toxicity in 12 children. Long-term treatment with LPV/r-based cART is safe and effective in HIV-1-infected children.

Anemia is a frequent complication among HIV-infected persons and is associated with faster disease progression and mortality. We examined the effect of multivitamin supplementation on hemoglobin concentrations and the risk of anemia among HIV-infected pregnant women and their children. HIV-1-infected pregnant women (n = 1078) from Dar es Salaam, Tanzania, were enrolled in a double-blind trial and provided daily supplements of preformed vitamin A and beta-carotene, multivitamins (vitamins B, C, and E), preformed vitamin A and beta-carotene + multivitamins, or placebo. All women received iron and folate supplements only during pregnancy according to local standard of care. The median follow-up time for hemoglobin measurement for mothers was 57.3 mo [interquartile range (IQR): 28.6-66.8] and for children it was 28.0 mo (IQR: 5.3-41.7). During the whole period, hemoglobin concentrations among women who received multivitamins were 0.33 g/dL higher than among women who did not receive multivitamins (P=0.07). Compared with placebo, multivitamin supplementation resulted in a hemoglobin increase of 0.59 g/dL during the first 2 y after enrollment (P=0.0002). Compared with placebo, the children born to mothers who received multivitamins had a reduced risk of anemia. In this group, the risk of macrocytic anemia was 63% lower than in the placebo group (relative risk: 0.37: 95% CI: 0.18, 0.79; P=0.01). Multivitamin supplementation provided during pregnancy and in the postpartum period resulted in significant improvements in hematologic status among HIV-infected women and their children, which provides further support for the value of multivitamin supplementation in HIV-infected adults.

Pediatric antiretroviral therapy (ART), changed the prognosis of the disease, allowing young women infected by vertical transmission (TV) to be pregnant without risk for their fetus of acquiring this infection. To describe the clinical-immune status in pregnant women that acquired HV by vertical transmission, treatments received, monitoring of pregnancy and newborn characteristics. A protocol was performed, evaluating clinical and immunological parameters during pregnancy, ART used, protocol preventing vertical transmission (PPTV), and follow up of children to 18 months of age. Of 358 HIV-positive patients vertically infected, five women became pregnant, between 14 and 24 years old. Pregnancies were controlled in clinical/immune-stage N2 C3. They had received two to five therapies. Full PPTV was performed in all binomials. Pre-natal undetectable viral loads ranged from 4,700 ARN copies/mL. Five living children were born by Caesarean section, four of them with 37 weeks of completed gestation and one of them with 34 weeks of gestation. All received zidovudine (AZT) for 6 weeks. CD4 at 72 hours of life ranged from 48% to 74.6%. All children were born uninfected with HIV. Only two had mild anemia. Expectations of HIV mothers vertically infected to have healthy children are similar to those infected by horizontal transmission, using PPTV.

Due to the high cost and limited serotype coverage of pneumococcal conjugate vaccines (PCV), pneumococcal common protein antigens (CPAs) are being investigated as potential vaccine candidates. CPAs are likely to be immunogenic in infants and could confer serotype-independent protection. There are limited data on natural antibody kinetics against CPAs in African populations. We aimed to determine the prevalence of naturally acquired antibody titres to 15 CPAs and explore their association to concurrent pneumococcal nasopharyngeal colonization in children aged 4-7 years with and without underlying HIV-infection and/or previous PCV-vaccination. A 15-plex Luminex assay was established to measure serum IgG titres against "cell-wall associated or surface-exposed" proteins (PspA, PspC, LytB, IgA1-proteinase, SP0082, PdB and PcsB), "membrane-associated" proteins (PsaA, SP0609, SP0749, PpmA, SlrA, StkP and SP2194) as well as the hypothetical protein, SP2027. Archived serum samples from HIV-uninfected (n=212) and HIV-infected (n=74) children were analyzed. Concurrent pneumococcal nasopharyngeal colonization was determined with standard microbiological methods. HIV-uninfected children had significantly higher antibody titres against PspA, PspC, PdB, SP0082, LytB, IgA1 proteinase and PcsB compared to HIV-infected children. In contrast, antibody titres against membrane associated proteins (PsaA, SP2027, PpmA and SlrA) were significantly lower in HIV-uninfected compared to HIV-infected children. Higher antibody titres against PdB, and PcsB were associated with the absence of pneumococcal colonization. There was no association between anti-CPA titres and PCV vaccination. In conclusion PdB and PcsB antigens are potential vaccine-candidates which may protect against pneumococcal colonization and consequently pneumococcal disease. Copyright © 2013 Elsevier Ltd.

Background Candidiasis is the most common opportunistic infection seen in human immunodeficiency virus (HIV)-infected individuals. The aim of our study was to estimate the candidiasis rate and evaluate its trend in HIV-infected children in Spain during the era of highly active antiretroviral therapy (HAART) compared to HIV-uninfected children. Methods We carried out a retrospective study. Data were obtained from the records of the Minimum Basic Data Set from hospitals in Spain. All HIV-infected children were under 17 years of age, and a group of HIV-uninfected children with hospital admissions matching the study group by gender and age were randomly selected. The follow-up period (1997–2008) was divided into three calendar periods: a) From 1997 to 1999 for early-period HAART; b) from 2000 to 2002 for mid-period HAART; and c) from 2003 to 2008 for late-period HAART. Results Among children with hospital admissions, HIV-infected children had much higher values than HIV-uninfected children during each of the three calendar periods for overall candidiasis rates (150.0 versus 6.1 events per 1,000 child hospital admissions/year (p < 0.001), 90.3 versus 3.1 (p < 0.001), and 79.3 versus 10.7 (p < 0.001), respectively) and for non-invasive Candida mycosis (ICM) rates (118.5 versus 3.8 (p < 0.001), 85.3 versus 2.3 (p < 0.001), and 80.6 versus 6.0 (p < 0.001), respectively). In addition, HIV-infected children also had higher values of ICM rates than HIV-uninfected children, except during the last calendar period when no significant difference was found (32.4 versus 1.2 (p < 0.001), 11.6 versus 0.4 (p < 0.001), and 4.6 versus 2.3 (p = 0.387), respectively). For all children living with HIV/AIDS, the overall candidiasis rate (events per 1,000 HIV-infected children/year) decreased from 1997–1999 to 2000–2002 (18.8 to 10.6; p < 0.001) and from 2000–2002 to 2003–2008 (10.6 to 5.7; p = 0.060).

To explore the financial implications of applying the WHO guidelines for the nutritional management of HIV-infected children in a rural South African HIV programme. WHO guidelines describe Nutritional Care Plans (NCPs) for three categories of HIV-infected children: NCP-A: growing adequately; NCP-B: weight-for-age z-score (WAZ) ≤-2 but no evidence of severe acute malnutrition (SAM), confirmed weight loss/growth curve flattening, or condition with increased nutritional needs (e.g. tuberculosis); NCP-C: SAM. In resource-constrained settings, children requiring NCP-B or NCP-C usually need supplementation to achieve the additional energy recommendation. We estimated the proportion of children initiating antiretroviral treatment (ART) in the Hlabisa HIV Programme who would have been eligible for supplementation in 2010. The cost of supplying 26-weeks supplementation as a proportion of the cost of supplying ART to the same group was calculated. A total of 251 children aged 6 months to 14 years initiated ART. Eighty-eight required 6-month NCP-B, including 41 with a WAZ ≤-2 (no evidence of SAM) and 47 with a WAZ >-2 with co-existent morbidities including tuberculosis. Additionally, 25 children had SAM and required 10-weeks NCP-C followed by 16-weeks NCP-B. Thus, 113 of 251 (45%) children were eligible for nutritional supplementation at an estimated overall cost of $11 136, using 2010 exchange rates. These costs are an estimated additional 11.6% to that of supplying 26-week ART to the 251 children initiated. It is essential to address nutritional needs of HIV-infected children to optimise their health outcomes. Nutritional supplementation should be integral to, and budgeted for, in HIV programmes. © 2012 Blackwell Publishing Ltd.

Pharmacotherapy of Pediatric HIV Infection

SYNOPSIS With the ongoing epidemic of human immune deficiency virus (HIV) infections in the pediatric age group, the delivery of safe and effective antiretroviral therapy to children and adolescents is crucial to save the lives of millions of children worldwide. Antiretroviral drugs have been demonstrated to significantly decrease HIV-associated morbidity and mortality, assure normal growth and development, and improve survival and quality of life in children and adolescents. The immunologic response to HIV infection is closely related to the child’s development and creates age specific parameters for the evaluation of therapeutic response to antiretroviral therapy in pediatric HIV disease. In addition to the changes in immunological response to HIV infection, the development and maturation of organ systems involved in drug absorption, distribution, metabolism, and elimination determines significant changes in the pharmacokinetics of antiretroviral drugs throughout the childhood. Multiple factors including age-specific adherence barriers, changes in social and economical surroundings, and psychological and sexual maturation affect the choices and outcomes of the treatment of pediatric HIV disease. In this chapter we will review the evolution of antiretroviral treatment from early infancy through adolescence. PMID:23036246

Growth faltering and micronutrient deficiencies commonly coexist in HIV-exposed children in sub-Saharan Africa, and correcting deficiencies, such as those of vitamins B-complex, C, and E, may improve HIV-related endpoints and child growth. We therefore examined the effect of daily oral supplementation of vitamins B-complex, C, and E on growth among 2341 children born to HIV-infected mothers in Tanzania. HIV-infected women pregnant at ≤32 wk of gestation were enrolled in the study. Children were randomized at age 6 wk to receive multivitamins or placebo until age 104 wk. All women received the same types of vitamins pre- and postnatally. At 6 wk, 256 children (11.1%) were HIV infected and the mean (SD) Z-scores for length for age (LAZ), weight for length (WLZ), and weight for age (WAZ) were −0.39 ± 1.20, −0.21 ± 1.23, and −0.52 ± 1.11, respectively. There was no overall treatment effect on LAZ, WLZ, or WAZ profiles during the follow-up (P ≥ 0.15). There was no treatment effect from 6 to 104 wk on LAZ [(95% CI: −0.14, 0.13); P = 0.94], WLZ [(95% CI: −0.17, 0.13); P = 0.78], or WAZ [(95% CI: −0.15, 0.16); P = 0.97] or on the incidence of growth failure, defined as respective Z-scores < −2 (P ≥ 0.29). Among the subgroup of HIV-uninfected children, there was no treatment effect from 6 to 104 wk on LAZ, WLZ, and WAZ (P ≥ 0.71) or on the incidence of growth failure (P ≥ 0.16). Multivitamin supplements had no effect on growth among children born to HIV-infected women who were themselves receiving multivitamins. PMID:23514773

Human rhinovirus (RV) is the most common respiratory virus and has been associated with frequent and severe acute lower respiratory infections (ALRI). The prevalence of RV species among HIV-infected children in South Africa is unknown. To describe the prevalence of respiratory viruses, including RV species, associated with HIV status and other clinical symptoms in children less than two years of age with and without ALRI in Pretoria, South Africa. Nasopharyngeal aspirates were collected from 105 hospitalized ALRI cases and 53 non-ALRI controls less than two years of age. HIV status was determined. Common respiratory viruses were identified by PCR, and RV species and genotypes were identified by semi-nested PCR, sequencing and phylogenetic tree analyses. Respiratory viruses were more common among ALRI cases than controls (83.8% vs. 69.2%; p=0.041). RV was the most commonly identified virus in cases with pneumonia (45.6%) or bronchiolitis (52.1%), regardless of HIV status, as well as in controls (39.6%). RV-A was identified in 26.7% of cases and 15.1% of controls while RV-C was identified in 21.0% of cases and 18.9% of controls. HIV-infected children were more likely to be diagnosed with pneumonia than bronchiolitis (p<0.01). RSV was not identified in any HIV-infected cases (n=15) compared with 30.6% of HIV-uninfected cases (n=85, p=0.013), and was identified more frequently in bronchiolitis than in pneumonia cases (43.8% vs. 12.3%; p<0.01). RV-A and RV-C are endemic in South African children and HIV infection may be protective against RSV and bronchiolitis. Copyright © 2016 Elsevier B.V. All rights reserved.

Vitamin A supplementation starting at 6 months of age is an important child survival intervention; however, not much is known about the association between vitamin A status before 6 months and mortality among children born to HIV-infected women. Plasma concentrations of vitamins A and B-12 were available at 6 weeks of age (n = 576 and 529, respectively) for children born to HIV-infected women and they were followed up for morbidity and survival status until 24 months after birth. Children in the highest quartile of vitamin A had a 49% lower risk of death by 24 months of age compared to the lowest quartile (HR: 0.51, 95% CI: 0.29–0.90; P-value for trend = 0.01). Higher vitamin A levels were protective in the sub-groups of HIV-infected and un-infected children but this was statistically significant only in the HIV-uninfected subgroup. Higher vitamin A concentrations in plasma are protective against mortality in children born to HIV-infected women. PMID:19502599

Background In low-income countries and those with a high prevalence of HIV, respiratory failure is a common cause of death in children. However, the role of non-invasive ventilation with bubble continuous positive airway pressure (bCPAP) in these patients is not well established. Methods A prospective observational study of bCPAP was undertaken between July and September 2012 in 77 Malawian children aged 1 week to 14 years with progressive acute respiratory failure despite oxygen and antimicrobial therapy. Results Forty-one (53%) patients survived following bCPAP treatment, and an HIV-uninfected single-organ disease subgroup demonstrated bCPAP success in 14 of 17 (82%). Compared with children aged ≥60 months, infants of 0–2 months had a 93% lower odds of bCPAP failure (odds ratio 0.07, 95% confidence interval 0.004–1.02, P = 0.05). Following commencement of bCPAP, respiratory physiology improved, the average respiratory rate decreased from 61 to 49 breaths/minute (P = 0.0006), and mean oxygen saturation increased from 92.1% to 96.1% (P = 0.02). Conclusions bCPAP was well accepted by caregivers and patients and can be feasibly implemented into a tertiary African hospital with high-risk patients and limited resources. PMID:25434361

Nontyphoidal Salmonella is a leading cause of sepsis in African children. Cytokine responses are central to the pathophysiology of sepsis and predict sepsis outcome in other settings. In this study, we investigated cytokine responses to invasive nontyphoidal Salmonella (iNTS) disease in Malawian children. We determined serum concentrations of 48 cytokines with multiplexed immunoassays in Malawian children during acute iNTS disease (n = 111) and in convalescence (n = 77). Principal component analysis and logistic regression were used to identify cytokine signatures of acute iNTS disease. We further investigated whether these responses are altered by HIV coinfection or severe malnutrition and whether cytokine responses predict inpatient mortality. Cytokine changes in acute iNTS disease were associated with two distinct cytokine signatures. The first is characterized by increased concentrations of mediators known to be associated with macrophage function, and the second is characterized by raised pro- and anti-inflammatory cytokines typical of responses reported in sepsis secondary to diverse pathogens. These cytokine responses were largely unaltered by either severe malnutrition or HIV coinfection. Children with fatal disease had a distinctive cytokine profile, characterized by raised mediators known to be associated with neutrophil function. In conclusion, cytokine responses to acute iNTS infection in Malawian children are reflective of both the cytokine storm typical of sepsis secondary to diverse pathogens and the intramacrophage replicative niche of NTS. The cytokine profile predictive of fatal disease supports a key role of neutrophils in the pathogenesis of NTS sepsis. Copyright © 2016 Gilchrist et al.

The burden of malnutrition among HIV-infected children is not well described in sub-Saharan Africa, even though it is an important problem to take into account to guarantee appropriate healthcare for these children. We assessed the prevalence of malnutrition and its associated factors among HIV-infected children in HIV care programmes in Central and West-Africa. A cross-sectional study was conducted from September to December 2011 among the active files of HIV-infected children aged 2-19 years old, enrolled in HIV-care programmes supported by the Sidaction Growing Up Programme in Benin, Burundi, Cameroon, Côte d'Ivoire, Mali, Chad and Togo. Socio-demographics characteristics, anthropometric, clinical data, and nutritional support were collected. Anthropometric indicators, expressed in Z-scores, were used to define malnutrition: Height-for-age (HAZ), Weight-for-Height (WHZ) for children < 5 years and BMI-for-age (BAZ) for children ≥5 years. Three types of malnutrition were defined: acute malnutrition (WHZ/BAZ < -2 SD and HAZ ≥ -2 SD), chronic malnutrition (HAZ < -2 SD and WHZ/BAZ ≥ -2 SD) and mixed malnutrition (WHZ/BAZ < -2 SD and HAZ < -2 SD). A multinomial logistic regression model explored associated factors with each type of malnutrition. Overall, 1350 HIV-infected children were included; their median age was 10 years (interquartile range [IQR]: 7-13 years), 49 % were girls. 80 % were on antiretroviral treatment (ART), for a median time of 36 months. The prevalence of malnutrition was 42 % (95 % confidence interval [95% CI]: 40-44 %) with acute, chronic and mixed malnutrition at 9 % (95% CI: 6-12 %), 26 % (95% CI: 23-28 %), and 7 % (95% CI: 5-10 %), respectively. Among those malnourished, more than half of children didn't receive any nutritional support at the time of the survey. Acute malnutrition was associated with male gender, severe immunodeficiency, and the absence of ART; chronic malnutrition with male gender and age (<5

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.

Disclosure of Their HIV Status to Infected Children: A Review of the Literature

Since the introduction of highly active antiretroviral therapy (ART) in 1996, HIV-infected children often survive beyond adolescence. To assess worldwide trends in disclosure since ART was introduced, we reviewed articles that refer to disclosure of their status to HIV-infected children, and which described patient, health care provider and/or caregiver opinions about disclosure and/or reported the proportion of children who knew their diagnosis. Most studies (17 [55%]) were performed in low- or middle-income (LMI) countries. In the 21 articles that included information on whether the children knew their status, the proportion who knew ranged from 1.2 to 75.0% and was lower in LMI (median = 20.4%) than industrialized countries (43%; p = 0.04). LMI country study participants who knew their status tended to have learned it at older ages (median = 9.6 years) than industrialized country participants (median = 8.3 years; p = 0.09). The most commonly reported anticipated risks (i.e. emotional trauma to child and child divulging status to others) and benefits (i.e. improved ART adherence) of disclosure did not vary by the country’s economic development. Only one article described and evaluated a disclosure process. Despite recommendations, most HIV-infected children worldwide do not know their status. Disclosure strategies addressing caregiver concerns are urgently needed. PMID:23070738

Measles infection in HIV-infected African infants.

Measles infection remains a serious threat to child survival in the developing world despite vaccination and treatment with vitamin A. This report reviews the epidemiology of measles in HIV-infected children in Africa. In hospitalized infants, the rate of malnutrition before measles and the rate of death after measles are both higher in HIV-positive than in HIV-negative infants. However, the rates of pneumonia and diarrhea in infants hospitalized with measles are the same in HIV-positive as in HIV-negative infants. In an autopsy study, measles was associated with death in HIV-positive children, only for those over 15 months of age. A cohort study found that infants of HIV-positive women were more likely than infants of HIV-negative women to have measles before 9 months of age, although the rates of complications did not differ between the two groups. The HIV status of the infants and the measles serology were too incomplete to draw firm conclusions, though only 1 of 54 infants tested was seropositive for measles at 6 months of age. In the context of the HIV epidemic, further work is needed to determine the risk of measles and its complications in HIV-positive infants and the optimal age of measles immunization.

The association of childhood tuberculosis (TB) and malnutrition is known, but treatment response, the influence of the acute-phase response (APR) and concomitant HIV infection are not well documented. To evaluate the nutritional response and APR in HIV-infected and uninfected children hospitalised for the treatment of TB and receiving standard anti-tuberculosis chemotherapy. During a study of the pharmacokinetics of standard anti-tuberculosis agents, anthropometric parameters were measured and blood concentrations of nutrients and C-reactive protein (CRP) determined at 1 and 4 months after initiation of chemotherapy. 24 HIV-infected and 34 HIV-uninfected children were studied. On enrollment, 31.6% of HIV-infected and 2.9% of HIV-uninfected children were underweight, and 31.6% and 14.7%, respectively, were stunted. Mean values of weight, height/length, head circumference and mid-upper-arm circumference on enrollment and at 4-month assessment in HIV-infected and uninfected children did not differ. Mean triceps skinfold (TSF) (8.17 and 9.73 cm) and subscapular skinfold (SSF) thicknesses (5.75 and 7.5 cm) on enrollment differed significantly (P = 0.03 and P = 0.003); by 4 months, TSF had declined to 5.97 cm (P<0.001) and 8.87 cm (P = 0.05), respectively, and SSF to 5.57 cm (P = 0.79) and 6.73 cm (P = 0.04); the arm muscle area (AMA) was low in a majority of children on enrollment and remained so at the second assessment. CRP was raised in 66.6% and 53.3% of HIV-infected and -uninfected children on enrollment, but at 4-month assessment was raised in 63.2% and 15.2%, respectively. Other micronutrient and haematological findings probably reflect an APR, but no children had sub-normal zinc or magnesium values; most selenium and vitamin C and E values were normal. An elevated platelet count (> 420 × 10(9)/L) was significantly more common in HIV-uninfected children, and was still raised in 39% at 4 months. A majority of HIV-infected and uninfected children had an APR but it

To assess the prevalence of the oral lesions related to HIV-infection (HIV-OL) in HIV+/AIDS adolescents (=13 years old), and the differences with HIV+/AIDS children (=3 - <13 years old) perinatally infected. 25 HIV+/AIDS adolescents and 62 HIV+/AIDS children, undergoing Highly Active Antiretroviral Therapy, were orally examined. HIV-OL was diagnosed in accordance with EC-Clearinghouse-World Health Organization. The patients were classifies with respect to their immune status in relation with the CD4+ cell counts as moderately immunodeficient; mildly immunodeficient and severely immunodeficient in accordance to the revised surveillance case definitions for HIV infection among adults, adolescents, and children aged <18 months and for HIV infection and AIDS among children aged 18 months to <13 years (CDC-USA). The virological status was established in relation to the copies of RNA-HIV-1/mL as follows: with undetectable viral load (UDVL); with low viral load and with high viral load. A chi-square test was performed (p<0.05 IC95%). The prevalence of HIV-OL in HIV+/AIDS adolescents was 20% while in HIV/AIDS children was 30.6% (p>0.05). Oral candidiasis was the most prevalent oral lesion in both groups. Association (p<0.05) of a high prevalence of HIV-OL and oral candidiasis with a high viral load was observed in both study groups. Adolescents perinatally HIV-infected have a high prevalence of HIV-OL. Oral Candidiasis still is the most frequent oral opportunistic infection. Oral lesions could have association to viral failure in HIV+/AIDS adolescents undergoing HAART.

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. 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. 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. 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.

Vitamin deficiencies are frequent in children suffering from malaria. The effects of maternal multivitamin supplementation on the risk of malaria in children are unknown. We examined the impact of providing multivitamins or vitamin A/beta-carotene supplements during pregnancy and lactation to HIV-infected women on their children's risk of malaria up to 2 years of age, in a randomized, placebo-controlled trial. Tanzanian women (N = 829) received one of four daily oral regimens during pregnancy and after delivery: 1) vitamins B, C, and E (multivitamins); 2) vitamin A and beta-carotene (VA/BC); 3) multivitamins including VA/BC; or 4) placebo. After 6 months of age, all children received 6-monthly oral vitamin A supplements irrespective of treatment arm. The incidence of childhood malaria was assessed through three-monthly blood smears and at monthly and interim clinic visits from birth to 24 months of age. Compared with placebo, multivitamins excluding VA/BC reduced the incidence of clinical malaria by 71% (95% CI = 11-91%; P = 0.02), whereas VA/BC alone resulted in a nonsignificant 63% reduction (95% CI = -4% to 87%; P = 0.06). Multivitamins including VA/BC significantly reduced the incidence of high parasitemia by 43% (95% CI = 2-67%; P = 0.04). The effects did not vary according to the children's HIV status. Supplementation of pregnant and lactating HIV-infected women with vitamins B, C, and E might be a useful, inexpensive intervention to decrease the burden of malaria in children born to HIV-infected women in sub-Saharan Africa.

In order to describe the prevalence of hypercholesterolemia and hypertriglyceridemia in a cohort of HIV-infected children and adolescents in Latin America and to determine associations with highly active antiretroviral therapy (HAART), we performed this cross-sectional analysis within the NICHD International Site Development Initiative pediatric cohort study. Eligible children had to be at least 2 years of age and be on HAART. Among the 477 eligible HIV-infected youth, 98 (20.5%) had hypercholesterolemia and 140 (29.4%) had hypertriglyceridemia. In multivariable analyses, children receiving protease inhibitor (PI)-containing HAART were at increased risk for hypercholesterolemia [adjusted odds ratio (AOR) = 2.7, 95% confidence interval (CI) 1.3–5.6] and hypertriglyceridemia (AOR = 3.5, 95% CI 1.9–6.4) compared with children receiving non-nucleoside reverse transcriptase inhibitor (NNRTI)-containing HAART. In conclusion, HIV-infected youth receiving PI-containing HAART in this Latin American cohort were at increased risk for hypercholesterolemia and hypertriglyceridemia compared with those receiving NNRTI-containing HAART.

Perinatal use of combination antiretroviral therapy dramatically reduces vertical (mother-to-child) transmission of HIV but has led to a growing population of children with perinatal HIV-exposure but uninfected (HEU). HIV can cause neurological injury among children born with infection, but the neuroanatomical and developmental effects in HEU children are poorly understood. We used structural magnetic resonance imaging with diffusion tensor imaging to compare brain anatomy between 30 HEU and 33 age-matched HIV-unexposed and uninfected (HUU) children from Thailand. Maps of brain volume and microstructural anatomy were compared across groups; associations were tested between neuroimaging measures and concurrent neuropsychological test performance. Mean (standard deviation) age of children was 10.3 (2.8) years, and 58% were male. All were enrolled in school and lived with family members. Intelligence quotient (IQ) did not differ between groups. Caretaker education levels did not differ, but income was higher for HUU (P < 0.001). We did not detect group differences in brain volume or diffusion tensor imaging metrics, after controlling for sociodemographic factors. The mean (95% confidence interval) fractional anisotropy in the corpus callosum was 0.375 (0.368-0.381) in HEU compared with 0.370 (0.364-0.375) in HUU. Higher fractional anisotropy and lower mean diffusivity were each associated with higher IQ scores in analyses with both groups combined. No differences in neuroanatomical or brain integrity measures were detectable in HEU children compared with age-matched and sex-matched controls (HUU children). Expected associations between brain integrity measures and IQ scores were identified suggesting sufficient power to detect subtle associations that were present.

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. © 2013 APJPH.

Women of reproductive age account for nearly half of all HIV-infected people worldwide. Childbearing intention among HIV-infected women is complicated by social and reproductive concerns related to their HIV status. We conducted a cross-sectional study of HIV-infected and HIV-uninfected sexually active South African women aged 17 to 21 in order to compare their childbearing intentions and to identify predictors of the desire to have children among women with HIV. We found the rate of childbearing intention to be similarly high among both HIV-infected and HIV-uninfected study participants (80 and 79% respectively, p=0.81). History of previous parity was found to be associated with decreased intention to have children. No difference in childbearing intention was found between HIV-infected women on anti-retroviral therapy (ART) and women not on ART. High rates of childbearing intention among HIV-infected women require integration of reproductive health services with comprehensive HIV/AIDS care in order to mitigate the risks of sexual and vertical transmission of HIV.

The number of human immunodeficiency virus (HIV)-infected children has increased because of the HIV and acquired immunodeficiency syndrome epidemic. Yet little is known about the child-rearing practices of these children's primary caregivers. The purpose of this article is to describe what is known about the child-rearing practices of primary caregivers of HIV-infected children. The review covers a 10-year period from 1990 to 2000. Three electronic bibliographic databases (MEDLINE, CINAHL, and AIDSLINE) were explored. Key words used were HIV-positive children, caregivers, and child-rearing. A total of 50 papers were examined. Using the Matrix Method, each paper was evaluated according to five frames of reference: journal, purpose, sample, method, and findings. Content analysis was used to identity salient themes. Themes that emerged were: caregiver, child, and interactions or child-rearing practices. These findings affirm the parent-child interaction model generated by Kathryn E. Barnard and support this framework as a tool for investigating the relationships between these children and their caregivers. Copyright 2002, Elsevier Science (USA). All rights reserved.

Background Tuberculosis (TB) is an important cause of illness and death in HIV-positive children living in areas of high TB prevalence. We know that isoniazid prophylaxis prevents TB in HIV-negative children following TB exposure, but there is uncertainty related to its role in TB preventive treatment in HIV-positive children. Objectives To summarise the effects of TB preventive treatment versus placebo in HIV-positive children with no known TB contact on active TB, death, and reported adverse events. Search methods We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE/PubMed, Embase and two trial registers up to February 2017. Selection criteria We included trials of HIV-positive children with and without known TB exposure, randomized to receive TB preventive treatment or placebo. Data collection and analysis Two review authors independently used the study selection criteria, assessed risk of bias, and extracted data. We assessed effects using risk, incidence rate and hazard ratios and assessed the certainty of evidence using GRADE. Main results We included three trials, involving 991 participants, below the age of 13 years, from South Africa and Botswana. Children were randomized to isoniazid prophylaxis or placebo, given daily or three times weekly. The median length of follow-up ranged from 5.7 to 34 months; some were on antiretroviral therapy (ART). In HIV-positive children not on ART, isoniazid prophylaxis may reduce the risk of active TB (hazard ratio (HR) 0.31, 95% confidence interval (CI) 0.11 to 0.87; 1 trial, 240 participants, low certainty evidence), and death (HR 0.46, 95% CI 0.22 to 0.95; 1 trial, 240 participants, low certainty evidence). One trial (182 participants) reported number of children with laboratory adverse events, which was similar between the isoniazid prophylaxis and placebo groups. No clinical adverse events were reported. In HIV-positive children on ART, we do not know if isoniazid prophylaxis reduces the

Bacterial infections in HIV-infected children admitted with severe acute malnutrition (SAM) contribute to higher mortality and poorer outcomes. This study describes the spectrum of bacterial infections in antiretroviral treatment (ART)-naïve, HIV-infected children admitted with SAM. Between July 2012 and February 2015, 82 children were prospectively enrolled in the King Edward VIII Hospital, Durban. Specimens obtained on and during admission for microbiological evaluation, if clinically indicated, included blood, urine (obtained by catheterisation or suprapubic aspiration), induced sputum and cerebrospinal fluid. All positive bacterial cultures between admission and 30 days after enrollment were documented and characterised into samples taken either within 2 days of admission (infections on admission) or within 2-30 days of admission (hospital-acquired infections, HAIs). On admission, 67% of patients had abnormal white blood cell counts (WBCC) (>12 or <4 × 10 9 /L) and 70% had elevated CRP; 65% were classified as severely immunosuppressed according to the WHO immunological classification. 1 A pathogen was isolated on the admission blood culture in four patients (6%) and in 27% of urine specimens. HAIs were predominately Gram-negative (39/43), and 39.5% were extended-spectrum β-lactamase-positive. Mortality was not significantly associated with isolation of a bacterial pathogen. Routine pre-hospital administration of antibiotics as per the Integrated Management of Childhood Illness (IMCI) guidelines may be responsible for the low rates of positive admission blood cultures. HAIs with drug-resistant Gram-negative organisms are an area of concern and strategies to improve the prevention of HAIs in this vulnerable population are urgently needed.

Early antiretroviral therapy (ART) has improved neurodevelopmental outcomes of HIV-infected (HIV-positive) children; however, little is known about the longer term outcomes in infants commencing early ART or whether temporary ART interruption might have long-term consequences. In the children with HIV early antiretroviral treatment (CHER) trial, HIV-infected infants ≤12 weeks of age with CD4 ≥25% were randomized to deferred ART (ART-Def); immediate time-limited ART for 40 weeks (ART-40W) or 96 weeks (ART-96W). ART was restarted in the time-limited arms for immunologic/clinical progression. Our objective was to compare the neurodevelopmental profiles in all three arms of Cape Town CHER participants. A prospective, longitudinal observational study was used. The Griffiths mental development scales (GMDS), which includes six subscales and a global score, were performed at 11, 20, 30, 42 and 60 months, and the Beery-Buktenica developmental tests for visual motor integration at 60 months. HIV-exposed uninfected (HEU) and HIV-unexposed (HU) children were enrolled for comparison. Mixed model repeated measures were used to compare groups over time, using quotients derived from standardized British norms. In this study, 28 ART-Def, 35 ART-40W, 33 ART-96W CHER children, and 34 HEU and 39 HU controls were enrolled. GMDS scores over five years were similar between the five groups in all subscales except locomotor and general Griffiths (interaction p < 0.001 and p = 0.02 respectively), driven by early lower scores in the ART-Def arm. At 60 months, scores for all groups were similar in each GMDS scale. However, Beery visual perception scores were significantly lower in HIV-infected children (mean standard scores: 75.8 ART-Def, 79.8 ART-40W, 75.9 ART-96W) versus 84.4 in HEU and 90.5 in HU (p < 0.01)). Early locomotor delay in the ART-Def arm resolved by five years. Neurodevelopmental outcomes at five years in HIV-infected children on early time-limited ART were

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.

To discuss recent research findings of neurologic complications in HIV-infected children, specifically addressing neuroinfections, cerebrovascular disease, epilepsy and neurocognitive complications. The range of neurologic childhood onset complications is diverse and often overlaps diseases previously considered only to manifest in adults. In the pediatric population, these complications frequently have their own unique disease identity, which may be related to maturational patterns evident in the developing brain. Developments regarding the pathogenesis of neuroAIDS, treatment of tuberculous meningitis and prevention of bacterial meningitis are described. With the advent of neuroimaging, there is greater insight into silent cerebrovascular events and the progression of vasculopathy in HIV-infected children. The role of surgical intervention for affected cases is a novel area that could alter the otherwise poor prognosis. Epilepsy, although common as a burden of disease, carries its own additional complications with regard to cross reactivity with various antiretroviral therapies. Increased risk of low bone mineral density supports a role for supplementation with vitamin D in people receiving antiretroviral therapy and antiepileptic drugs. Recognition of the early neurobiological, as well as spectrum of neurocognitive effects of the HIV on the developing brain, is evolving, as greater numbers of children are treated early. Developments in these critical areas are described. Recent research reflects the need for improved strategies to prevent neuroinfections, more effective screening and interventions for vasculopathy and better antiepileptic drugs for HIV-infected children. Furthermore, our understanding of the timing and spectrum of neurocognitive complications is evolving.

Accurate assessment of HIV-associated cognitive disorders in perinatally infected children and adolescents is challenging. Assessments of general intellectual functioning, or global cognition, may not provide information regarding domain-specific strengths and weaknesses, and may therefore fail to detect, impaired trajectories of development within particular cognitive domains. We compare the efficacy of global cognitive scores to that of composite cognitive domain scores in detecting cognitive disorders in a sample of perinatally HIV-infected children, and a demographically matched HIV negative control group, drawn from the Cape Town Adolescent Antiretroviral Cohort (CTAAC) study. All children were administered a comprehensive neuropsychological test battery. Using data from that test battery, we created ten separate composite cognitive domains: general intellectual functioning, attention, working memory, visual memory, verbal memory, language, visual spatial ability, motor coordination, processing speed and executive function. Within each domain, each test bore a high level of association with each of the other tests in that domain (Cronbach's α ≥ .70 for all domains). We found that composite domain scores calculated on whole-sample data were significantly higher than those calculated using control-sample data. Our comparison of a global cognitive score to composite domain scores suggested that the latter provided more detailed information (regarding strengths, weaknesses, areas of impairment), and when compared to global scores, were more sensitive in detecting HIV-associated cognitive disorders, and were able to distinguish HIV-infected patients from uninfected controls. Hence, we recommend using this method of composite cognitive domains scores, rather than global aggregate scores, when assessing cognitive function in paediatric HIV. This method provides a convenient and relatively accurate assessment that might help with cross-cultural and cross

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. © The Author(s) 2014.

To determine the magnitude and persistence of quadrivalent human papillomavirus (HPV)16 and HPV18 B-cell and T-cell memory after three or four doses of quadrivalent HPV vaccine (QHPV) in HIV-infected children. Seventy-four HIV-infected children immunized with four doses and 23 with three doses of QHPV had HPV16 and HPV18 IgG B-cell and IFNγ and IL2 T-cell ELISPOT performed at 2, 3.5 and 4-5 years after the last dose. HPV16 and HPV18 T-cell responses were similar in both treatment groups, with higher responses to HPV16 vs. HPV18. These HPV T-cell responses correlated with HIV disease characteristics at the study visits. Global T-cell function declined over time as measured by nonspecific mitogenic stimulation. B-cell memory was similar across treatment groups and HPV genotypes. There was a decline in HPV-specific B-cell memory over time that reached statistical significance for HPV16 in the four-dose group. B-cell and T-cell memory did not significantly differ after either three or four doses of QHPV in HIV-infected children. The clinical consequences of decreasing global T-cell function and HPV B-cell memory over time in HIV-infected children requires further investigation.

Three cases of meningitis due to criptococcus in children infected with HIV are reported. All patients had severe immunodeficiency. The first case occurred before antiretroviral therapy. The second case had poor adherence to treatment. The third case is a teenager with prolonged fever, who did not have a clear source of transmission of HIV and was immunodeficient at the time of diagnosis. Examination of cerebrospinal fluid with India ink dye was essential for making the diagnosis in all three cases. The disease course was adequate in all three patients despite flucytosine not being available.

Existing studies have delineated that HIV-infected parents face numerous challenges in disclosing their HIV infection to the children ("parental HIV disclosure"), and practices of parental HIV disclosure vary with individual characteristics, family contexts, and social environment. Using cross-sectional data from 1254 HIV-infected parents who had children aged 5-16 years in southwest China, the current study examined the association of parental HIV disclosure with mental health and medication adherence among parents and explored the possible effect of enacted stigma on such association. Multivariate analysis of variance revealed that parents who had experienced disclosure to children reported higher level enacted stigma, worse mental health conditions, and poorer medication adherence. Enacted stigma partially mediated the associations between disclosure and both mental health and medication adherence after controlling basic background characteristics. Our findings highlight the importance of providing appropriate disclosure-related training and counseling service among HIV-infected parents. In a social setting where HIV-related stigma is still persistent, disclosure intervention should address and reduce stigma and discrimination in the practice of parental HIV disclosure.

Culturally and developmentally appropriate parental HIV disclosure (i.e., parents disclose their HIV infection to children) has been shown to be closely related with the well-being of both HIV-infected parents and their children. However, current practices and effects of parental HIV disclosure remain poorly understood in low- and middle-income countries including China. Quantitative data from 626 children affected by parental HIV (orphans and vulnerable children) in Henan, China, were collected in 2011 to examine children's perceptions and knowledge regarding their parents' HIV disclosure practices and to assess the associations of these practices with children's demographic and psychosocial factors. The data in the current study revealed that only a small proportion of children learned parental HIV infection from their parents (direct disclosure), and many of these disclosure seemed being unplanned. Among the children who were not told by their parents, at least 95% of them either knew parental illness from others (indirect disclosure) or from their own observations or suspicions. The children reported similar disclosure practices by fathers and mothers. There were minimum differences between disclosed and nondisclosed children on a number of psychosocial measures. The findings support the notion that parental HIV disclosure is a complex process and can only be beneficial if it is carefully planned. The data in the current study suggest the needs for the culturally and developmentally appropriate approach in parental HIV disclosure in order to maximize both short- and long-term benefits to children, parents, and family functioning.

The prognostic and protective role of antibodies mediating cellular cytotoxicity (ADCC) and neutralization was evaluated in sera of HIV-1-infected mothers and their consecutively followed children. The presence and titres of ADCC mediating and/or neutralizing antibodies in maternal sera did not predict HIV-1 infection in their respective children. No significant difference in the sera from the children was seen when comparing the presence of neutralizing antibodies between the uninfected and infected children. Stratification of the infected group according to clinical status revealed differences. Only one of 24 AIDS patients had a high neutralizing titre against IIIB. Four patients had a very low titre and the remaining had no detectable neutralizing antibodies at all. In contrast, 10/17 infected non-AIDS children had neutralizing antibodies. Similarly, no significant difference was seen when comparing the presence of ADCC-mediating antibodies between the uninfected and the infected group of children. However, a significantly higher frequency of ADCC was seen in the seropositive non-AIDS children compared with the AIDS children. This study clearly shows that the presence of antibodies mediating ADCC and neutralization in infected children, 0-2 years old, is associated with a better clinical status and delayed disease progression.

Although antiretroviral treatment (ART) has reduced the incidence of HIV-related opportunistic infections among children living with HIV, access to ART remains limited for children, especially in resource-limited settings. This paper reviews current knowledge on the contribution of opportunistic infections and common childhood illnesses to morbidity and mortality in children living with HIV, highlights interventions known to improve the health of children, and identifies research gaps for further exploration. Literature review of peer-reviewed articles and abstracts combined with expert opinion and operational experience. Morbidity and mortality due to opportunistic infections has decreased in both developed and resource-limited countries. However, the burden of HIV-related infections remains high, especially in sub-Saharan Africa, where the majority of HIV-infected children live. Limitations in diagnostic capacity in resource-limited settings have resulted in a relative paucity of data on opportunistic infections in children. Additionally, the reliance on clinical diagnosis means that opportunistic infections are often confused with common childhood illnesseswhich also contribute to excess morbidity and mortality in these children. Although several preventive interventions have been shown to decrease opportunistic infection-related mortality, implementation of many of these interventions remains inconsistent. In order to reduce opportunistic infection-related mortality, early ART must be expanded, training for front-line clinicians must be improved, and additional research is needed to improve screening and diagnostic algorithms.

ABSTRACT Most patients with cerebral malaria (CM) sustain cerebral microvascular sequestration of Plasmodium falciparum-infected red blood cells (iRBCs). Although many young children are infected with P. falciparum, CM remains a rare outcome; thus, we hypothesized that specific host conditions facilitate iRBC cerebral sequestration. To identify these host factors, we compared the peripheral whole-blood transcriptomes of Malawian children with iRBC cerebral sequestration, identified as malarial-retinopathy-positive CM (Ret+CM), to the transcriptomes of children with CM and no cerebral iRBC sequestration, defined as malarial-retinopathy-negative CM (Ret-CM). Ret+CM was associated with upregulation of 103 gene set pathways, including cytokine, blood coagulation, and extracellular matrix (ECM) pathways (P < 0.01; false-discovery rate [FDR] of <0.05). Neutrophil transcripts were the most highly upregulated individual transcripts in Ret+CM patients. Activated neutrophils can modulate diverse host processes, including the ECM, inflammation, and platelet biology to potentially facilitate parasite sequestration. Therefore, we compared plasma neutrophil proteins and neutrophil chemotaxis between Ret+CM and Ret-CM patients. Plasma levels of human neutrophil elastase, myeloperoxidase, and proteinase 3, but not lactoferrin or lipocalin, were elevated in Ret+CM patients, and neutrophil chemotaxis was impaired, possibly related to increased plasma heme. Neutrophils were rarely seen in CM brain microvasculature autopsy samples, and no neutrophil extracellular traps were found, suggesting that a putative neutrophil effect on endothelial cell biology results from neutrophil soluble factors rather than direct neutrophil cellular tissue effects. Meanwhile, children with Ret-CM had lower levels of inflammation, higher levels of alpha interferon, and upregulation of Toll-like receptor pathways and other host transcriptional pathways, which may represent responses that do not favor

Some viruses of the Herpesviridae family are frequently the etiologic agents of oral lesions associated with HIV. The aim of this study was to identify the presence of herpes simplex virus types 1 and 2 (HSV-1, HSV-2), Varicella Zoster virus (VZV), Epstein-Barr virus (EBV), human cytomegalovirus (HCMV), human herpesvirus type 6, type 7 and type 8 (HHV-6, HHV-7 and HHV-8) in the oral cavity of HIV-infected children/adolescents and verify the association between viral subtypes and clinical factors. The cells of oral mucosa were collected from 50 HIV infected children/adolescents, 3-13 years old (mean age 8.66). The majority (66%) of selected were girls, and they were all outpatients at the pediatric AIDS clinic of a public hospital in Rio de Janeiro. Nested-PCR was used to identify the viral types. Absence of immunosuppression was observed in 66% of the children. Highly active antiretroviral therapy (HAART) was used by 72.1% of selected and moderate viral load was observed in 56% of the children/adolescents. Viral types were found in 86% of the children and the subtypes were: HSV-1 (4%), HSV-2 (2%), VZV (4%), EBV (0%), HCMV (24%), HHV6 (18%), HHV-7 (68%), HHV8 (0%). The use of HAART has helped to reduce oral lesions, especially with herpes virus infections. The health professionals who work with these patients should be aware of such lesions because of their predictive value and the herpes virus can be found circulating in the oral cavity without causing lesions.

Antibiotic use not only selects for resistance in pathogenic bacteria, but also in commensal flora of exposed individuals. Little is known epidemiologically about antibiotic resistance in relation to people with HIV infection in sub-Saharan Africa. This study investigated the carriage of antibiotic resistant bacteria among HIV infected children at a tertiary hospital in Ghana. One hundred and eighteen HIV positive children were recruited at the Korle-Bu Teaching Hospital in Ghana and nasopharyngeal specimens were collected from them. The specimens were cultured for bacteria, and the isolates were identified by standard microbiological methods. Antibiotic susceptibility tests were carried out on selected bacterial organisms by the Kirby Bauer method. Bacteria isolated from the study subjects included Moraxella catarrhalis (39.8%), coagulase negative staphylococci (33.1%), Streptococcus pneumoniae (30.5%), diptheroids (29.7%), viridian streptococci (27.1%), Staphylococcus aureus (22.0%), Citrobacter spp. (4.2%) and Neisseria meningitidis (0.9%). Prevalence of antibiotic resistance of S. pneumoniae ranged from 5.6% (ceftriaxone) to 58.3% (cotrimoxazole), M. catarrhalis ranged from 2.1% (gentamicin) to 80.6% (ampicillin), and S. aureus ranged from 7.7% (cefoxitin) to 100% (penicillin). The prevalence of multiple drug resistance was 16.7% for S. pneumoniae, 57.4% for M. catarrhalis and 84.6% for S. aureus. HIV infected children in the study area commonly carry multi-drug resistant isolates of several pathogenic bacteria such as S. aureus and S. pneumoniae. Infections arising in these patients that are caused by S. aureus and S. pneumoniae could be treated with ceftriaxone and cefoxitin respectively.

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 Maternal and child survival are highly correlated, but the contribution of HIV infection on this relationship, and in particular the impact of HIV treatment has not been quantified. We estimate the association between maternal HIV and treatment and under-5 child mortality in a rural population in South Africa. Methods All children born between January 2000-January 2007 in the Africa Centre Demographic Surveillance Area were included. Maternal HIV status information was available from HIV surveillance; maternal antiretroviral treatment (ART) from the HIV Treatment Programme database and linked to surveillance data. Mortality rates were computed as deaths per 1000 person-years observed. Time-varying maternal HIV effect (positive, negative, ART) on U5MR was assessed in Cox regression, adjusting for other factors associated with under-5 mortality. Results 9,068 mothers delivered 12,052 children, of whom 947 (7.9%) died before age 5. Infant mortality rate (IMR) declined by 49% from 69.0 in 2000 to 35.5 in 2006 deaths per 1000 person-years observed; a significantly decline was observed post-ART (2004-2006). The estimated proportion of deaths across all age groups were higher among the children born to the HIV-positive and HIV-not reported status women than among children of HIV-negative women. Multivariably, mortality in children of mothers on ART was not significantly different from children of HIV-negative mothers (aHR 1.29, 0.53-3.17; p=0.572). Conclusions These findings highlight the importance of maternal HIV treatment with direct benefits of improved survival among all children under-5. Timely HIV treatment for eligible women is required to benefit both mothers and children. PMID:22267472

Impaired cellular immune response to tetanus toxoid but not to cytomegalovirus in effectively HAART-treated HIV-infected children.

Alsina, Laia; Noguera-Julian, Antoni; Fortuny, Clàudia

Despite of highly active antiretroviral therapy, the response to vaccines in HIV-infected children is poor and short-lived, probably due to a defect in cellular immune responses. We compared the cellular immune response (assessed in terms of IFN-γ production) to tetanus toxoid and to cytomegalovirus in a series of 13 HIV-perinatally-infected children and adolescents with optimal immunovirological response to first line antiretroviral therapy, implemented during chronic infection. A stronger cellular response to cytomegalovirus (11 out of 13 patients) was observed, as compared to tetanus toxoid (1 out of 13; p=0.003). These results suggest that the repeated exposition to CMV, as opposed to the past exposition to TT, is able to maintain an effective antigen-specific immune response in stable HIV-infected pediatric patients and strengthen current recommendations on immunization practices in these children.

To determine the prevalence of HLA-B*5701 allele in HIV-infected children, and to find its association with Abacavir hypersensitivity. Children (2 to 18 y) already on, or to be initiated on Abacavir were included for PCR sequencing to detect HLA-B*5701. proportion with HLA B*5701 allele and hypersensitivity with Abacavir. Abacavir was stopped if patient tested positive for HLA-B*5701 allele. 100 children (median age 11 y) were enrolled; 10 were already on Abacavir. HLA-B*5701 positivity was observed in 11 (11%) children. Two of these 11 children developed hypersensitivity after initiation of Abacavir. Abacavir was thereafter stopped in all who tested HLA-B*5701 positive, irrespective of the development of hypersensitivity reaction. HLA-B*5701 allele was present in 11 (11%) of HIV-infected children, of which two developed Abacavir hypersensitivity. None of the patients without the allele developed hypersensitivity.

We analyzed a nationwide, stratified probability sample of 2.5 million hospital discharges of children and adolescents during the year 2000, weighted to 7.3 million discharges nationally. We excluded discharges after hospitalizations related to pregnancy/childbirth and their complications and discharges of neonates <1 month of age and of patients >18 years of age. Diagnoses were identified through the use of the Clinical Classification Software with grouping of related diagnoses. We estimated that there were 4107 hospitalizations of HIV-infected children in 2000 and that these hospitalizations accounted for approximately dollar 100 million in hospital charges and >30000 hospital days. Infections, including sepsis and pneumonia, were among the most frequent diagnoses in such hospitalizations, followed by diagnoses related to gastrointestinal conditions, nutritional deficiencies and anemia, fluid/electrolyte disorders, central nervous system disorders, cardiovascular disorders, and respiratory illnesses. Compared with hospitalizations of non-HIV-infected children, hospitalizations of HIV-infected ones were more likely to be in urban areas, in pediatric/teaching hospitals, and in the Northeast, and the expected payer was more likely to be Medicaid (77.6% vs 37.2%). Compared with children without HIV, those with HIV tended to be older (median age: 9.5 years vs 5.2 years), to have been hospitalized longer (mean: 7.8 days vs 3.9 days), and to have incurred higher hospital costs (mean: dollar 23221 vs dollar 11215); HIV-associated hospitalizations ended in the patient's death more frequently than non-HIV ones (1.8% vs 0.4%), and complications of medical care were also more common (10.8% vs 6.2%). Infections account for the majority of hospitalizations of HIV-infected children in the United States, although nutritional deficiencies, anemia and other hematologic

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

Human Immunodeficiency Virus infection is a multisystem disease that contributes to significant morbidity. Renal involvement is reported to be common among patients with HIV. This study was carried out to determine renal involvement using simple bedside tests combined with ultrasonography examination. We recruited 240 children from the HIV clinic at Muhimbili National Hospital. Data were collected using structured questionnaires and included demographic, clinical information, radiological tests; renal ultrasound and laboratory tests; serum creatinine, white blood cells, CD4+ counts and percent, urine for microalbuminuria and proteinuria. Microalbuminuria and proteinuria were present in 20.4 % and 7.1 % respectively. Significantly higher prevalence of microalbuminuria (p < 0.01) and proteinuria p < 0.01) were noted with low CD4 percent (<25 %). Lower mean CD4+ count were noted among children with microalbuminuria [937.4 ± 595.3 cells/μL vs 1164.7 ± 664.3 cell/μL, (p < 0.05)] and proteinuria [675.5 ± 352.3 cells/μL vs 1152 ± 662 cells/μL (p < 0.001)]. Fourteen (5.8 %) HIV infected children had estimated glomerular filtration rate (eGFR of 30-59) consistent with severe renal impairment. Increased cortical echogenicity was noted in 69/153 (39.2 %) of participants who had ultrasound examination. Microalbuminuria, proteinuria and renal dysfunction were noted to be prevalent among HIV infected children indicating the need to consider routine screening of renal complications in these children.

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.

The effectiveness of highly active antiretroviral therapy (HAART) in children has not been well studied specially in developing countries where the burden of HIV is high. This study was aimed to assess the immunologic response of HIV-infected children to HAART at Pediatric ART Clinic Gondar University Hospital. Institution based cross-sectional study was conducted at the Pediatric ART Clinic Gondar University Hospital from March 01-April 30, 2014. The study included 283 HIV-infected children who were on HAART for 6 months and above. Medical records of HIV-infected children were reviewed using pre-tested questionnaire. CD4 count/percent was collected every 6 months retrospectively. For all statistical significance tests, the cut-off value was p<0.05. Poison Regression was used for further analysis. The mean age of children was 6.9 years with a standard deviation of 3.4 years. The median CD4 count/percent was 232/13%, 450/21%, 540/25% and 608/27% at the time of initiation, 6, 12 and 18 months of ART, respectively. HAART initiated at higher CD4 count, good adherence and HIV status disclosure were found to have positive effects for immunological response. The study revealed that there was good Immunological response to ART, and that the maximum response was in the 1(st) 6 months of ART. Low CD4 count at initiation, undisclosed HIV status and lack of good adherence were found to cause low immunological response to HAART.

In the absence of early infant diagnosis (EID) and immediate antiretroviral therapy (ART), some 50% of untreated HIV-infected infants die before age 2. Conventional EID requires sophisticated instruments that are typically placed in centralized or reference laboratories. In low-resource settings, centralized systems often lead to result turnaround times of several months, long delays in diagnosis, and adverse outcomes for HIV-infected children. Our clinical trial tests the effectiveness of a new point-of-care (POC) diagnostic technology to identify HIV-infected infants and start providing them life-saving ART as soon as possible. The study uses a randomized, controlled design to test whether the Alere q platform for HIV DNA polymerase chain reaction (PCR) testing improves outcomes of HIV-infected children in Zambia. We aim to enroll 2867 HIV-exposed infants aged 4-12 weeks and to follow those who are HIV infected for 12 months as they receive HIV care at 6 public health facilities in Lusaka. The trial's primary endpoint is the proportion of HIV-infected infants in each study arm who start ART and remain alive, in care, and virally suppressed 12 months after their diagnostic blood draw. Our trial will provide evidence for the incremental benefit of implementing a POC EID strategy in low-resource settings where only off-site PCR services are currently available. The results will be useful in guiding future decisions regarding investments in POC virologic testing as part of overall pediatric AIDS mitigation strategies in sub-Saharan Africa. clinicaltrials.gov NCT02682810.

Background Dyslipidemia is a common complication among HIV-infected children after antiretroviral therapy (ART). However, HIV itself can cause abnormal lipid metabolism. There is limited information of lipid profile among Asian HIV-infected children naïve to ART. Methods 274 HIV-infected ART-naïve Thai and Cambodian children 1–12 years of age with CD4 between 15–24% were included. Patients were fasted for ≥ 4 hours before blood was drawn. Abnormal lipid level was defined as triglyceride (TG) > 130 mg/dL, total cholesterol (TC) > 200 mg/dL, low density lipoprotein (LDL) > 130 mg/dL, and high density lipoprotein (HDL) ≤ 40 mg/dL. Result The mean (SD) was 76.6 (33.8) months for age and −1.3 (1.0) for weight Z-score. Mean (SD) CD4% was 19.9 (4.8) % and HIV RNA was 4.6 (0.6) log10 copies/ml. The median (SD) fasting time was 13.0 (2.7) hours. Mean (SD) for lipids were 116 mg/dl (62) for TG, 139 mg/dl (29) for TC, 73 mg/dl (29) for LDL and 45 mg/dl (19) for HDL. Overall 63.9% had dyslipidemia with hypertriglyceridemia and hypo HDL being the most common: 28% and 45% respectively, while 2% had hypercholesterolemia or hyper-LDL. After adjusting for age, having HIV RNA > 5 log10 copies/ml was associated with hypo-HDL with odds ratios of 8.1 (95% CI 2.7–24.3). Conclusions Up to two-third of ART-naïve, HIV-infected Asian children with mild to moderate immune suppression had dyslipidemia. Low HDL was the most common and was associated with high HIV viremia. The long term consequence of low HDL deserves further investigation in children. PMID:22155918

Objective We examined the relationships between exclusive breast-feeding and the risks of respiratory, diarrhoea and nutritional morbidities during the first 2 years of life among children born to women infected with HIV-1. Design We prospectively determined the incidence of respiratory illnesses, diarrhoea, fever, hospitalizations, outpatient visits and nutritional morbidities. Generalized estimating equations were used to estimate the relative risks for morbidity episodes and Cox proportional hazards models to estimate the incidence rate ratios of nutritional morbidities. Setting Dar es Salaam, Tanzania. Subjects The sample consisted of 666 children born to HIV-infected women. Results The 666 children were followed for 2 years. Exclusive breast-feeding was associated with lower risk for cough (rate ratio (RR) = 0·49, 95 % CI 0·41, 0·60, P < 0·0001), cough and fever (RR = 0·44, 95 % CI 0·32, 0·60, P < 0·0001) and cough and difficulty breathing or refusal to feed (RR = 0·31, 95 % CI 0·18, 0·55, P < 0·0001). Exclusive breast-feeding was also associated with lower risk of acute diarrhoea, watery diarrhoea, dysentery, fever and outpatient visits during the first 6 months of life, but showed no effect at 6–24 months of life. Exclusive breast-feeding did not significantly reduce the risks of nutritional morbidities during the first 2 years of life. Conclusions Exclusive breast-feeding is strongly associated with reductions in the risk of respiratory and diarrhoea morbidities during the first 6 months of life among children born to HIV-infected women.

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

274 children were HIV-infected during 1988-89 in hospitals in the South of Russia during treatment of heavy pathology requiring an intensive therapy and catheterization of large venous vessels. Today only 140 children, receiving HAART now, remain alive. In 1988 - 89 mothers having nosocomially HIV-infected children were tested on a 'WHOQOL-100' technique (Russian version). Though the majority of mothers estimated the basic domains of quality of life (QoL) as average and good, the significant part considers their QoL as bad (in physical health, 22.7%, in psychological health, 20.4%, in environment, 25%, in social relationship, 11.4%). The least data of the test were in facets of financial resources, medical and social help and 47.7% consider a general QoL and condition of health as bad, 54.5% marks a lack of positive emotions, and 52.3% had plenty of negative emotions. 45.5% of mothers marked unsatisfactory opportunities for rest and entertainments, 31.8% of those interrogated had problems with an environment of a house. For the most part, mothers considered their health as 'neither bad, nor good' (63.9%), as 'basically bad' (9.1%), and 22.7% as 'basically good'. The basic problems are 'heart problems' (38.6%), 'increased blood pressure' (25%), 'chronic nervous/emotional problems' (36.4%), 'depression' (31.8%). The absence of problems with health was noted by only 9.1% of those surveyed. Overall, 54.5% of mothers considered themselves as patients, and 22.7% as requiring medical treatment 'rather urgently'. At the same time, only 11.4% had received stationary treatment 'in the last 2 weeks', and 15.9%, any out-patient treatment. The problems of QoL and of psychosocial rehabilitation of mothers having nosocomially HIV-infected children are discussed.

Mothers living with HIV face a complex set of child-rearing decisions, often within the context of many competing stressors. One difficult decision for HIV-infected mothers is whether to disclose their HIV status to their children. The purpose of this study is to provide information to HIV-affected families and the professionals working with them as they approach disclosure-related decisions. Eighty-seven HIV-infected African American mothers and one of their children who was not HIV-infected were separately interviewed on two occasions. Mothers reported whether they disclosed their HIV status to the child and provided their assessment of the child's functioning. Children also completed an assessment of their functioning. Results revealed that less than one-third of mothers disclosed their HIV status to their children. Disclosure was associated with mother's income level and perceived severity of physical symptoms. In addition, children disclosed to were more often older and female. Contrary to expectation, disclosure was not related to child functioning. Professionals should note the low rate of disclosure among these families. In the absence of conclusive data regarding impact on child functioning, professionals must remain aware of the complexity of disclosure-related decisions when working with HIV-affected families, particularly in terms of the family and cultural milieu within which families operate.

This paper reviews the English language literature on the safety, immunogenicity and effectiveness in children infected with the human immunodeficiency virus (HIV) of vaccines currently recommended by WHO for use in national immunization programmes. Immunization is generally safe and beneficial for children infected with HIV, although HIV-induced immune suppression reduces the benefit compared with that obtained in HIV-uninfected children. However, serious complications can occur following immunization of severely immunocompromised children with bacillus Calmette-Gu rin (BCG) vaccine. The risk of serious complications attributable to yellow fever vaccine in HIV-infected persons has not been determined. WHO guidelines for immunizing children with HIV infection and infants born to HIV-infected women differ only slightly from the general guidelines. BCG and yellow fever vaccines should be withheld from symptomatic HIV-infected children. Only one serious complication (fatal pneumonia) has been attributed to measles vaccine administered to a severely immunocompromised adult. Although two HIV-infected infants have developed vaccine-associated paralytic poliomyelitis, several million infected children have been vaccinated and the evidence does not suggest that there is an increased risk. The benefits of measles and poliovirus vaccines far outweigh the potential risks in HIV-infected children. The policy of administering routine vaccines to all children, regardless of possible HIV exposure, has been very effective in obtaining high immunization coverage and control of preventable diseases. Any changes in this policy would have to be carefully examined for a potential negative impact on disease control programmes in many countries. PMID:12640478

Background Perinatally HIV-infected children (PHIV) may be at risk of undervaccination. Vaccination coverage rates among PHIV and HIV-exposed uninfected children (HEU) in Latin America and the Caribbean were compared. Methods All PHIV and HEU children born from 2002–2007 that were enrolled in a multi-site observational study conducted in Latin America and the Caribbean were included in this analysis. Children were classified as up to date (UTD) if they had received the recommended number of doses of each vaccine at the appropriate intervals by 12 and 24 months of age. Fisher’s exact test was used to analyze the data. Covariates potentially associated with a child’s HIV status were considered in multivariable logistic regression modeling. Results Of 1156 eligible children, 768 (66.4%) were HEU and 388 (33.6%) were PHIV. HEU children were significantly (p<0.01) more likely to be UTD by 12 and 24 months of age for all vaccines examined. Statistically significant differences persisted when the analyses were limited to children enrolled prior to 12 months of age. Controlling for birth weight, sex, primary caregiver education and any use of tobacco, alcohol or illegal drugs during pregnancy did not contribute significantly to the logistic regression models. Conclusions PHIV children were significantly less likely than HEU children to be UTD for their childhood vaccinations at 12 and 24 months of age, even when limited to children enrolled before 12 months of age. Strategies to increase vaccination rates in PHIV are needed. PMID:23860480

Malnutrition, growth retardation and opportunistic infections outlast the metabolic, immune and gastrointestinal disorders produced by HIV. Zinc deficiency has been associated with deteriorating nutritional status, growth failure, and risk of infection. The aim of this study is to determine the association between zinc levels in peripheral blood mononuclear cells (PBMC) and the nutritional status of HIV-infected and uninfected children exposed to the virus. An analytical, observational, cross-sectional study was conducted on 17 infected and 17 exposed children, aged 2-10 years. Anthropometric measurements, clinical and nutritional history, 24h recall, measurement of physical activity, and zinc in PBMC by flow cytometry analysis were recorded. Height according to age, energy consumption and adequacy of energy, protein and dietary zinc were significantly higher in children exposed to the virus compared to those infected with HIV (P <.05). No significant differences were found in BMI, levels of zinc in monocytes, CD4 + and CD4- lymphocytes between the two study groups (P >.05). However, the median levels of zinc in monocytes of infected patients was higher (218.6) compared to the control group (217.0). No association was found between zinc intake and levels of intracellular zinc. The deterioration of nutritional status and growth retardation in children were associated with HIV, but not with the levels of intracellular zinc. The dietary intake of this nutrient was not associated with levels of zinc in monocytes or CD4 + and CD4- lymphocytes. Copyright © 2015. Publicado por Elsevier España, S.L.U.

Background Little is known concerning the impact of HIV status disclosure on quality of life, leaving clinicians and families to rely on research of children with other terminal illnesses. Objectives The purpose of this work was to examine the impact of HIV disclosure on pediatric quality of life and to describe the distribution of age at disclosure in a perinatally infected pediatric population. Methods A longitudinal analysis was conducted of perinatally HIV-infected youth ≥5 years of age enrolled in a prospective cohort study, Pediatric AIDS Clinical Trials Group 219C, with ≥1 study visit before and after HIV disclosure. Age-specific quality-of-life instruments were completed by primary caregivers at routine study visits. The distribution of age at disclosure was summarized. Six quality-of-life domains were assessed, including general health perception, symptom distress, psychological status, health care utilization, physical functioning, and social/role functioning. For each domain, mixed-effects models were fit to estimate the effect of disclosure on quality of life. Results A total of 395 children with 2423 study visits were analyzed (1317 predisclosure visits and 1106 postdisclosure visits). The median age at disclosure was estimated to be 11 years. Older age at disclosure was associated with earlier year of birth. Mean domain scores were not significantly different at the last undisclosed visit compared with the first disclosed visit, with the exception of general health perception. When all of the visits were considered, 5 of 6 mean domain scores were lower after disclosure, although the differences were not significant. In mixed-effects models, disclosure did not significantly impact quality of life for any domain. Conclusions Age at disclosure decreased significantly over time. There were no statistically significant differences between predisclosure and postdisclosure quality of life; therefore, disclosure should be encouraged at an appropriate time

Mitochondrial damage is implicated in highly active antiretroviral therapy (HAART) toxicity. HIV infection also causes mitochondrial toxicity (MT). Differentiating between the two is critical for HIV management. Our objective was to test the utility of the Mitochondrial Disease Criteria (MDC) and the Enquête Périnatale Française (EPF) to screen for possible HAART related MT in HIV-infected children in Ghana. The EPF and MDC are compilations of clinical symptoms, or criteria, of MT: a (+) score indicates possible MT. We applied these criteria retrospectively to 403 charts of HIV-infected children. Of those studied, 331/403 received HAART. Comparing HAART exposed and HAART naïve children, the difference in EPF score, but not MDC, approached significance (P = 0.1). Young age at HIV diagnosis or at HAART initiation was associated with (+) EPF (P ≤ 0.01). Adherence to HAART trended toward an association with (+) EPF (P = 0.09). Exposure to nevirapine, abacavir, or didanosine increased risk of (+) EPF (OR = 3.55 (CI = 1.99-6.33), 4.76 (2.39-9.43), 4.93 (1.29-18.87)). Neither EPF nor MDC identified a significant difference between HAART exposed or naïve children regarding possible MT. However, as indicators of HAART exposure are associated with (+) EPF, it may be a candidate for prospective study of possible HAART related MT in resource-poor settings.

Debilitating rickets-like lower limb deformities are common in children throughout the world, particularly in Malawi, Africa where the causes are unknown. We have identified that Blount disease and calcium deficiency rickets are the likely causes of these deformities and propose calcium supplementation as a potential treatment of Malawian rickets. Surgical correction of rickets-like lower limb deformities is the most common paediatric operation performed at Beit Cure Orthopaedic Hospital, Malawi. The aim of this study was to investigate the aetiology of these deformities. Children with a tibio-femoral angle of deformity >20° were enrolled (n = 42, 3.0-15.0 years). Anthropometric and early life and well-being data were collected. Early morning serum and urine samples were collected on the morning of the operation for markers of calcium and phosphate homeostasis. Knee radiographs were obtained, and the children were diagnosed with either Blount (BD, n = 22) or evidence of rickets disease (RD, n = 20). As BD is a mechanical rather than metabolic disease, BD were assumed to be biochemically representative of the local population and thus used as a local reference for RD. There were no differences in anthropometry or early life experiences between BD and RD. Parathyroid hormone (PTH), 1,25-dihydroxyvitamin D, total alkaline phosphatase and urinary phosphate were significantly higher and serum phosphate, 25-hydroxyvitamin D (25OHD) and tubular maximal reabsorption of phosphate significantly lower in RD than BD. There was no difference in serum calcium, fibroblast growth factor 23 or markers of iron status between groups. All children had 25OHD > 25 nmol/L. Vitamin D deficiency is not implicated in the aetiology of RD or BD in Malawian children. The cause of RD in Malawi is likely to be dietary calcium deficiency leading to elevated PTH resulting in increased losses of phosphate from the bone and glomerular filtrate. The causes of BD remain unclear

Background. South Africa introduced 7-valent pneumococcal conjugate vaccine (PCV7) in April 2009 using a 2 + 1 schedule (6 and 14 weeks and 9 months). We estimated the effectiveness of ≥2 PCV7 doses against invasive pneumococcal disease (IPD) in human immunodeficiency virus (HIV)–infected and -uninfected children. Methods. IPD (pneumococcus identified from a normally sterile site) cases were identified through national laboratory-based surveillance. Specimens were serotyped by Quellung or polymerase chain reaction. Four controls, matched for age, HIV status, and hospital were sought for each case. Using conditional logistic regression, we calculated vaccine effectiveness (VE) as 1 minus the adjusted odds ratio for vaccination. Results. From March 2010 through November 2012, we enrolled 187 HIV-uninfected (48 [26%] vaccine serotype) and 109 HIV-infected (43 [39%] vaccine serotype) cases and 752 HIV-uninfected and 347 HIV-infected controls aged ≥16 weeks. Effectiveness of ≥2 PCV7 doses against vaccine-serotype IPD was 74% (95% confidence interval [CI], 25%–91%) among HIV-uninfected and −12% (95% CI, −449% to 77%) among HIV-infected children. Effectiveness of ≥3 doses against vaccine-serotype IPD was 90% (95% CI, 14%–99%) among HIV-uninfected and 57% (95% CI, −371% to 96%) among HIV-infected children. Among HIV-exposed but -uninfected children, effectiveness of ≥2 doses was 92% (95% CI, 47%–99%) against vaccine-serotype IPD. Effectiveness of ≥2 doses against all-serotype multidrug-resistant IPD was 96% (95% CI, 62%–100%) among HIV-uninfected children. Conclusions. A 2 + 1 PCV7 schedule was effective in preventing vaccine-serotype IPD in HIV-uninfected and HIV-exposed, uninfected children. This finding supports the World Health Organization recommendation for this schedule as an alternative to a 3-dose primary series among HIV-uninfected individuals. PMID:24917657

Antimicrobial resistance is an emerging global health issue. Data on the epidemiology of multidrug-resistant organisms are scarce for Africa, especially in HIV-infected individuals who often have frequent contact with healthcare. We investigated the prevalence of extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-E) carriage in stool among HIV-infected children attending an HIV outpatient department in Harare, Zimbabwe. We recruited children who were stable on antiretroviral therapy (ART) attending a HIV clinic from August 2014 to June 2015. Information was collected on antibiotic use and hospitalization. Stool was tested for ESBL-E through combination disc diffusion. API20E identification and antimicrobial susceptibility was performed on the positive samples followed by whole genome sequencing. Stool was collected from 175/202 (86.6 %) children. Median age was 11 [inter-quartile range (IQR) 9-12] years. Median time on ART was 4.6 years (IQR 2.4-6.4). ESBL-Es were found in 24/175 samples (13.7 %); 50 % of all ESBL-Es were resistant to amoxicillin-clavulanate, 100 % to co-trimoxazole, 45.8 % to chloramphenicol, 91.6 % to ceftriaxone, 20.8 % to gentamicin and 62.5 % to ciprofloxacin. ESBL-Es variously encoded CTX-M, OXA, TEM and SHV enzymes. The odds of ESBL-E carriage were 8.5 times (95 % CI 2.2-32.3) higher in those on ART for less than one year (versus longer) and 8.5 times (95 % CI 1.1-32.3) higher in those recently hospitalized for a chest infection. We found a 13.7 % prevalence of ESBL-E carriage in a population where ESBL-E carriage has not been described previously. Antimicrobial resistance (AMR) in Africa merits further study, particularly given the high HIV prevalence and limited diagnostic and therapeutic options available.

HIV-infected children and adolescents may be at risk for cardiovascular disease due to chronic inflammation and exacerbation of risk factors. The aim of this study was as follows: 1) compare cardiovascular risk factors, chronic inflammation, and carotid intima-media thickness (IMTc) between the HIV and control groups; 2) determine the association of HIV and antiretroviral (ART) regimens with cardiovascular risk factors, chronic inflammation, and IMTc; and 3) identify variables associated with elevated IMTc. Cross-sectional analysis of 130 children and adolescents, 8-15 years of age, divided into HIV-infected (n = 65) and healthy control (n = 65) participants. Body fat, blood pressure, glycemia, insulin, and glycated hemoglobin, total cholesterol and fractions (LDL-C and HDL-C), triglycerides, C-reactive protein (CRP), interleukin (IL)-6, tumor necrosis factor-alpha (TNF-α), and the IMTc were measured. The results showed HIV-infected children and adolescents had higher levels of glycemia (87.9 vs. 75.9 mg.dL-1, p< 0.001), LDL-c (94.7 vs. 79.5 mg.dL-1, p = 0.010), triglycerides (101.2 vs. 61.6 mg.dL-1, p< 0.001), CRP (1.6 vs. 1.0 mg.L-1, p = 0.007), IL-6 (1.42 vs. 0.01 pg.mL-1, p< 0.001), TNF-α (0.49 vs. 0.01 pg.mL-1, p< 0.001), mean IMTc (0.526 vs. 0.499 mm, p = 0.009), and lower HDL-c (53.7 vs. 69.4 mg.dL-1, p< 0.001) compared to controls. Systolic blood pressure (β = 0.006, p = 0.004) and TNF-α (β = -0.033, p = 0.029) accounted for 16% of IMTc variability in HIV-infected children and adolescents. In patients using protease inhibitors-based ART, male gender (β = -0.186, p = 0.008), trunk body fat (β = -0.011, p = 0.006), glucose (β = 0.005, p = 0.046), and IL-6 (β = 0.017, p = 0.039) accounted for 28% of IMTc variability. HIV-infected children and adolescents may be at risk for premature atherosclerosis due to chronic inflammation and dyslipidemia.

Secondary infectious diseases contribute substantially to morbidity and mortality of people infected with human immunodeficiency virus (HIV). The authors developed comprehensive, practical recommendations for prevention of infectious complications in HIV-infected people. Recommendations are concerned with the pathogens that are more common or more severe in HIV-infected people. Several infectious complications can be prevented by avoiding ingestion of contaminated food or water. Zoonoses can be prevented by precautions to be taken in contacts with animals. The risk of several fungal diseases can be reduced if activities likely to lead to inhalation of spores are avoided. HIV-infected people should be advised how to lower adverse health effects of travel, especially international travel. The potential for infectious complications of sexual activity and illicit drug use should be stressed, and recommendations to reduce the risk are discussed. Recommendations for use of vaccines in HIV-infected people are reviewed. Blood CD4+ lymphocyte concentrations, tuberculin skin testing, Toxoplasma serology, and sexually transmitted disease screening should be performed in certain subsets of HIV-infected people. Guidelines for chemoprophylaxis against Pneumocystis carinii and tuberculosis are presented. Recent data suggest that intravenous immunoglobulin therapy may prevent bacterial infections in HIV-infected children. PMID:1910184

Objective Adult caregivers provide children living with HIV with varying amounts and types of information about their health status that may affect their coping and health care behaviors. We aimed to describe patterns of information-sharing with children and thoughts around disclosure among caregivers in the Democratic Republic of the Congo. Methods 259 primary caregivers of children 5–17 years old in an HIV pediatric care and treatment program were screened; 8 adult caregivers (3%) had informed their child of the child’s HIV status. We conducted structured interviews with 201 caregivers whose children had not yet been told their HIV status. Results Nearly 50% of caregivers provided no information to their child about their health; 15% had given partial information without mentioning HIV, and 33% provided information that deflected attention from HIV, whether deliberately so or otherwise. Almost all caregivers said that the child should be told their status some day, and three-fourths reported having ever thought about what might lead them to tell. However, nearly one-third of caregivers saw no benefits to informing the child of her/his HIV status. A majority of caregivers felt that they themselves were the best to eventually disclose to the child, but some wanted support from health care providers. Conclusion HIV-infected children are given limited information about their health. Health care providers may serve as important sources of support to caregivers as they decide when and how to talk candidly with their children about their health. PMID:21317803

To evaluate the efficacy, visual outcomes, and complications of intravitreous ganciclovir treatment in cytomegalovirus (CMV) retinitis in HIV-infected children. The medical records of HIV-infected children who were screened for CMV retinitis from February 2002 to February 2005 were reviewed. The children with CD4+ < 15%, or with clinical category C would have complete ophthalmic examination every 3 months. Ganciclovir (4 mg/0.04 ml) was administered intravitreously to the eye with CMV retinitis every 2 weeks under general anaesthesia. After injection, fundi were examined immediately, 1 day, 14 days and every 2 weeks until the lesions were stable. Six (9 eyes) out of 45 children (13%) aged 2-12 years were found to have CMV retinitis. All CMV retinitis lesions were "cheese and ketchup like" (retinal hemorrhage and exudate) lesions and presented in the posterior pole. Bilateral CMV retinitis were found in 3 children. Intravitreous ganciclovir was injected in 4 children (5 eyes). The average number of intravitreous injections for each patient was 5.6 (3-7) times. All of the children received antiretroviral therapy and 3 children also received intravenous ganciclovir CMV retinitis lesions were improved in every eye. The visual acuity (VA) remained stable in 4 eyes, but endophthalmitis developed in one eye a few days after injection. The average duration of follow-up was 13.5 months (3-23 months). CMV retinitis was not uncommon. The authors found that intravitreous ganciclovir was effective but may cause complications. This treatment should be considered in a resource-limited setting.

Diarrhea is an important health problem among HIV-infected patients. This study evaluates the role of HIV on the epidemiology, etiology and severity of diarrheal disease among children. The Global Enteric Multicenter Study enrolled children with moderate-to-severe (MSD) and less severe (LSD) diarrhea between December 2007 and November 2012. One to three controls for MSD cases and one per LSD case were enrolled and matched by age, sex and neighborhood. All children were tested for HIV. Clinical, anthropometric data and stools were collected. A follow-up was performed at 60 days. 214 MSD cases and 418 controls, together with 349 LSD cases and 214 controls were tested. HIV prevalence among MSD cases was 25% (4% for matched controls) and 6% among LSD cases (6% among matched controls). HIV-infected children were more likely to have MSD (OR=5.6, p< 0.0001). Mortality rates were higher among HIV-infected children compared with uninfected (34 vs. 5 per 1000 children-weeks at risk; p=0.0039). Cryptosporidium, Giardia, EAEC (aatA only) were more prevalent among HIV-infected MSD-cases than uninfected ones. HIV is an important risk factor for MSD. The high mortality rate implies that children with MSD should be screened for HIV and managed accordingly. Copyright © 2018. Published by Elsevier Ltd.

Background Combination antiretroviral therapy (ART) has been used for HIV-infected children in many Asian countries since 2002. This study describes survival outcomes among HIV-infected children in a multicenter regional cohort in Asia. Patients and Methods Retrospective and prospective data collected through March 2009 from children in five countries enrolled in TREAT Asia's Pediatric HIV Observational Database (TApHOD) were analysed. Multivariate Cox proportional hazard models were used to assess factors associated with mortality in children who received ART. Results Among 2280 children, 1752 (77%) had received ART. During a median follow up of 3.1 years after ART, 115 (6.6%) deaths occurred, giving a crude mortality rate of 1.9 per 100 child-years (95% CI, 1.6-2.4). The mortality rate was highest in the first three months of ART (10.2 per 100 child-years; 95% CI, 7.5-13.7) and declined after 12 months (0.9 per 100 child-years; 95% CI, 0.7-1.3). Those with a low recent CD4 percentage, who started ART with lower baseline weight-for-age z-score, or with WHO clinical stage 4 had an increased risk of death. Of 528 (23%) children who never received ART, 36 (6.8%) died after presenting to care, giving a crude mortality rate of 4.1 per 100 child-years (95% CI 3.0-5.7), with a lost-to-program rate of 31.5 per 100 child-years (95% CI, 28.0-35.5). Conclusion The high mortality during the first three months of ART and in those with low CD4 percentage support the implementation of early diagnosis and ART initiation. PMID:21160429

Anemia results in increased morbidity and mortality, underscoring the need to better understand its pathophysiology amongst HIV-exposed and infected children in sub-Saharan Africa, the region where most infant HIV exposure and infections occur. This analysis used samples obtained from children in the Kisumu Breastfeeding Study (KiBS). KiBS was a longitudinal phase IIB, open-label, one-arm clinical trial, designed to investigate the safety, tolerability and effectiveness of a maternal triple-antiretroviral (ARV) regimen for prevention of mother-to-child transmission (PMTCT) of HIV, during late pregnancy and early infancy while breastfeeding. Blood samples from 482 children were obtained at birth, 2, 6, 10 and 14 weeks and 6, 9, 12, 18 and 24 months. Severity of anemia was graded using the NIH Division of AIDS (DAIDS) toxicity tables. We describe the proportion of children with anemia and anomalies in red blood cell parameters at various time points over 24 months and compare rates of anemia between HIV-infected and HIV-uninfected children and by mothers' ARV regimen and infant malaria infection. The proportion of children with anemia significantly increased after the breastfeeding period in both HIV-infected and HIV-uninfected children with higher proportion among HIV-infected children compared to HIV-uninfected children (RR: 1.72; CI: 1.22-2.44, p = 0.002). Maternal triple-antiretroviral regimen was not associated with infant anemia (p = 0.11). There was no significant difference in mean hemoglobin between HIV-uninfected children with and without malaria at each time point except at 24 months. A relatively lower proportion of children with severe anemia during the breastfeeding period suggest that exposure to mother's triple antiretroviral combinations through breast milk, posed minimal risk of hematologic toxicity.

We assessed a nutritional support intervention in malnourished HIV-infected children in a HIV-care program of the University Hospital Gabriel Touré, Bamako, Mali. All HIV-infected children younger than 15 years were diagnosed for malnutrition between 07 and 12, 2014. Malnutrition was defined according to the WHO growth standards with Z-scores. Two types were studied: acute malnutrition (AM) and chronic malnutrition (CM). All participants were enrolled in a 6-month prospective interventional cohort, receiving Ready-To-Use Therapeutic Food, according to type of malnutrition. The nutritional intervention was offered until child growth reached -1.5 SD threshold. Six-month probability to catch up growth (>-2 SD) was assessed for AM using Kaplan-Meier curves and Cox model. Among the 348 children screened, 198 (57%) were malnourished of whom 158 (80%) children were included: 97 (61%) for AM (35 with associated CM) and 61 (39%) with CM. Fifty-nine percent were boys, 97% were on antiretroviral therapy, median age was 9.5 years (Interquartile Range: 6.7-12.3). Among children with AM, 74% catch-up their growth at 6-month; probability to catch-up growth was greater for those without associated CM (adjusted Hazard Ratio = 1.97, CI 95%: 1.13 to 3.44). Anemia decreased significantly from 40% to 12% at the end of intervention (P < 0.001). This macronutrient intervention showed 6-month benefits for weight gain and reduced anemia among these children mainly on antiretroviral therapy for years and aged greater than 5 years at inclusion. Associated CM slows down AM recovery and needs longer support. Integration of nutritional screening and care in the pediatric HIV-care package is needed to optimize growth and prevent metabolic disorders.

Maternal weight loss during exclusive breastfeeding may influence the growth of exclusively breast-fed infants through impaired quality or quantity of breast milk. This study evaluated how maternal weight loss from 2 to 24 wk postpartum was related to infant weight and length gain in 1309 lactating HIV-infected mothers and their exclusively breast-fed infants. Malawian mother-infant pairs in the Breastfeeding, Antiretrovirals, and Nutrition Study were randomized with a 2 × 3 factorial design to a 2-arm nutritional intervention with a lipid-based nutrient supplement (LNS), meeting nutritional needs of lactation, or no LNS and a 3-arm antiretroviral (ARV) intervention (maternal, infant, or no ARV regimen). Linear regression models were used to relate maternal weight loss (weight loss vs. no weight loss) to infant weight and length gain from birth to 24 mo, stratifying by gender and controlling for maternal BMI at 2 wk (mean ± SD: 23.2 ± 3.0 kg/m(2)) and interacting maternal BMI with weight loss. In adjusted models, compared with daughters of women who did not lose weight, length and weight gain were lower in daughters whose mothers had a lower BMI at 2 wk postpartum coupled with the weight loss. For example, among mothers with an initial BMI of 18 kg/m(2), daughters of those who lost weight gained less weight [β = -0.29 kg (95% CI: -0.53, -0.06)] and length [β = -0.88 cm (95% CI: -1.52, -0.23)] from birth to 24 wk than daughters of those who gained weight. Though effects were only observed in girls, suggesting possible gender differences in suckling and feeding behavior, these findings indicate that maternal weight loss with low energy reserves represents a risk factor for poor infant growth outcomes.

Katz, Karol; Northrup, Veronika

Mitochondrial damage is implicated in highly active antiretroviral therapy (HAART) toxicity. HIV infection also causes mitochondrial toxicity (MT). Differentiating between the two is critical for HIV management. Our objective was to test the utility of the Mitochondrial Disease Criteria (MDC) and the Enquête Périnatale Française (EPF) to screen for possible HAART related MT in HIV-infected children in Ghana. The EPF and MDC are compilations of clinical symptoms, or criteria, of MT: a (+) score indicates possible MT. We applied these criteria retrospectively to 403 charts of HIV-infected children. Of those studied, 331/403 received HAART. Comparing HAART exposed and HAART naïve children, the difference in EPF score, but not MDC, approached significance (P = 0.1). Young age at HIV diagnosis or at HAART initiation was associated with (+) EPF (P ≤ 0.01). Adherence to HAART trended toward an association with (+) EPF (P = 0.09). Exposure to nevirapine, abacavir, or didanosine increased risk of (+) EPF (OR = 3.55 (CI = 1.99–6.33), 4.76 (2.39–9.43), 4.93 (1.29–18.87)). Neither EPF nor MDC identified a significant difference between HAART exposed or naïve children regarding possible MT. However, as indicators of HAART exposure are associated with (+) EPF, it may be a candidate for prospective study of possible HAART related MT in resource-poor settings. PMID:23533730

HIV/AIDS creates a massive burden of care for health systems. A better understanding of the impact of HIV infection on health care utilization and costs may enable better use of limited resources. We compared public sector inpatient costs of HIV-infected versus uninfected adults and children at a large hospital in Soweto, South Africa. Daily hotel costs estimated from hospital financial data and total patient visits were combined with utilization, abstracted from patients' charts, and costed using government price lists to estimate total inpatient costs. A total of 1185 eligible records were included over a 6-week period in 2005. Eight hundred twelve were from HIV-infected patients, and of these, 77 were on antiretroviral (ARV) therapy. The mean length of stay (LOS) and mean drug and intravenous fluid utilization of HIV-infected adults not on ARVs was greater than those of uninfected adults, resulting in a $200 higher total average admission cost. Patients on ARVs had longer LOS and incurred a total average admission cost of $750 more than HIV-infected adults not on ARVs. Inpatient costs were greater for this selected group of HIV-infected adults, and even higher for the small proportion of individuals receiving ARVs. Budget allocations should incorporate case mix by HIV and ARV status as a key determinant of hospital expenditure.

HIV Testing, Subjective Beliefs and Economic Behavior

This paper examines the effects of learning HIV status on economic behavior among rural Malawians. According to economic life-cycle models, if learning HIV results is informative about additional years of life, being diagnosed HIV-positive or negative should predict changes in consumption, investment and savings behavior with important micro and macro-economic implications. Using an experiment that randomly assigned incentives to learn HIV results, I find that while learning HIV results had short term effects on subjective belief of HIV infection, these differences did not persist after two years. Consistent with this, there were relatively few differences two years later in savings, income, expenditures, and employment between those who learned and did not learn their status. PMID:24369439

Live-attenuated influenza vaccine (LAIV) prevents more cases of influenza in immune-competent children than the trivalent inactivated vaccine (TIV). We compared the antibody responses to LAIV or TIV in HIV-infected children. Blood and saliva obtained at enrollment, 4 and 24 weeks postimmunization from 243 HIV-infected children randomly assigned to TIV or LAIV were analyzed. Both vaccines increased the anti-influenza neutralizing antibodies at 4 and 24 weeks postimmunization. At 4 weeks postimmunization, TIV recipients had 2-fold to 3-fold higher neutralizing antibody titers than LAIV recipients, but the proportions of subjects with protective titers (≥ 1:40) were similar between treatment groups (96%-100% for influenza A and 81%-88% for influenza B). Both vaccines increased salivary homotypic IgG antibodies, but not IgA antibodies. Both vaccines also increased serum heterosubtypic antibodies. Among HIV-specific characteristics, the baseline viral load correlated best with the antibody responses to either vaccine. We used LAIV-virus shedding as a surrogate of influenza infection. Influenza-specific humoral and mucosal antibody levels were significantly higher in nonshedders than in shedders. LAIV and TIV generated homotypic and heterosubtypic humoral and mucosal antibody responses in HIV-infected children. High titers of humoral or mucosal antibodies correlated with protection against viral shedding.

The relationship between HIV-related stigma and health-related quality of life (HRQoL) among children living with HIV infection is unknown. The objectives of this study were to describe HIV-related stigma and HRQoL among children with perinatal HIV living in Sweden, and to investigate the relationship between these two factors in the same infection group. In a cross-sectional nationwide survey, HIV-related stigma was measured with the 8-item HIV Stigma Scale for Children. HRQoL was measured with the 37-item DISABKIDS Chronic Generic Module. Structural equation modeling was used to explore the relationship between HIV-related stigma and HRQoL. Fifty-eight children participated, age 9-18 years (mean = 13.9). The HIV stigma general scale showed a mean score of 17.6 (SD = 5.0; possible range 8-32). DISABKIDS Chronic Generic Module general scale showed a mean score of 80.7 (SD = 14.1; possible range 0-100). HIV-related stigma was negatively associated with HRQoL (standardized β = -0.790, p = .017). The results indicate that children's concerns related to disclosure of their HIV infection seem to be common (i.e. 75% agreed) which, together with the negative association between ratings of HIV-relatively stigma and HRQoL, might indicate that disclosure concerns would be a relevant target for interventions to decrease HIV-related stigma and increase HRQoL.

This study aimed to determine changes in fertility intentions of HIV-1 infected and uninfected reproductive age women in Blantyre, Malawi. Participants were asked about their fertility intentions at baseline and at 3-month visits for 1 year. Time-to-event statistical models were used to determine factors associated with changes in fertility intentions. Overall, 842 HIV uninfected and 844 HIV infected women were enrolled. The hazard of changing from wanting no more children at baseline to wanting more children at follow-up was 61% lower among HIV infected women compared to HIV uninfected women (P < 0.01) after adjusting for other factors, while HIV infected women were approximately 3 times more likely to change to wanting no more children. The overall pregnancy rate after 12 months was 14.9 per 100 person-years and did not differ among 102 HIV uninfected and 100 infected women who became pregnant. HIV infection is a significant predictor of fertility intentions over time.

We examined HIV-infected parents' conversations about HIV prevention with their uninfected children, including what facilitated or hindered communication. Parents with HIV/AIDS (n = 90) who had children aged 10 to 18 years were recruited for a mixed method study from 2009 to 2010. Interviews assessed facilitators and barriers to discussing HIV prevention. A questionnaire identified the frequency and content of conversations, parental confidence level, and perceived importance of discussing preventive topics. Eighty-one percent of parents reported "sometimes" or "often" communicating about HIV prevention. A subset of parents found these conversations difficult; 44% indicated their desire for support. Facilitators to communication included utilizing support, focusing on the benefits of talking, and having a previous relationship with one's child. Barriers to discussions included fear of negative consequences, living in denial, and lacking a parental role model who discussed safer sex. Parents varied as to how they believed their HIV status affected communication. Those who did not disclose their HIV status to their children reported less frequent communication; self-efficacy partially mediated this relationship. Findings highlighted the need for communication skills training that support HIV-infected parents in their efforts to discuss HIV-related information with adolescents.

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

Antiretroviral therapy has had a great impact on the prevention of mother-to-child transmission (MTCT) of HIV-1. However, development of drug resistance, which could be subsequently transmitted to the child, is a major concern. In Honduras and Belize the prevalence of drug resistance among HIV-1-infected children remains unknown. A total of 95 dried blood spot samples was obtained from HIV-1-infected, untreated children in Honduras and Belize born during 2001 to 2004, when preventive antiretroviral therapy was often suboptimal and consisted of monotherapy with nevirapine or zidovudine. Partial HIV-1 pol gene sequences were successfully obtained from 66 children (Honduras n=55; Belize n=11). Mutations associated with drug resistance were detected in 13% of the Honduran and 27% of the Belizean children. Most of the mutations detected in Honduras (43%) and all mutations detected in Belize were associated with resistance to nonnucleoside reverse transcriptase inhibitors, which was expected from the wide use of nevirapine to prevent MTCT during the study period. In addition, although several mothers reported that they had not received antiretroviral therapy, mutations associated with resistance to nucleoside reverse transcriptase inhibitors and protease inhibitors were found in Honduras. This suggests prior and unreported use of these drugs, or that these women had been infected with resistant virus. The present study demonstrates, for the first time, the presence of drug resistance-associated mutations in HIV-1-infected Honduran and Belizean children.

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

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 >5yrs 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

After active antiretroviral therapy, children with HIV are clinically well, whereas psychosocial issues continue to influence their quality of life. The International Classification of Functioning, Disability and Health (ICF) of the World Health Organization evaluates health status and environmental and social factors associated with health. We investigated the efficacy of the ICF to describe the health status and needs of a cohort of children and adolescents with HIV seen at a reference center for pediatric AIDS in Europe. A quantitative analysis of structured interviews was performed. Caregivers of children and adolescents with HIV infection in follow-up at 2 reference centers for pediatric AIDS were enrolled. Four major areas included in the ICF instrument were investigated: impairments of body structures; impairments of body functions; environmental factors; and activity limitations and restrictions to social life. Forty-one families of children with HIV were enrolled. Body structures and functions were marginally impaired, whereas environmental factors and psychosocial issues had a relevant impact on quality of life. Most families considered environmental factors to be "barriers"; these were poverty, unemployment, and single-parent family structure. Activity limitations and social restrictions were also reported in a few cases. Almost all parents reported problems in disclosing their child's HIV status because of the fear of social stigma. Psychosocial issues are part of the well-being of children with HIV. The ICF is a standard tool to evaluate the clinical and psychosocial status of children and adolescents with HIV infection and to measure the impact of therapeutic interventions and strategies on psychosocial functioning.

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). 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. 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. Measles revaccination induced high rates of seroprotection and memory in children receiving HAART. Both endpoints were associated with HIV viral load suppression.

Background We evaluated whether B cell-derived immune defenses of the gastro-intestinal tract are activated to produce HIV-specific antibodies in children continuously exposed to HIV via breast-feeding. Methods Couples of HIV-1-infected mothers (n = 14) and their breastfed non HIV-infected (n = 8) and HIV-infected (n = 6) babies, and healthy HIV-negative mothers and breastfed babies (n = 10) as controls, were prospectively included at the Complexe Pédiatrique of Bangui, Central African Republic. Immunoglobulins (IgA, IgG and IgM) and anti-gp160 antibodies from mother’s milk and stools of breastfed children were quantified by ELISA. Immunoaffinity purified anti-gp160 antibodies were characterized functionally regarding their capacity to reduce attachment and/or infection of R5- and X4- tropic HIV-1 strains on human colorectal epithelial HT29 cells line or monocyte-derived-macrophages (MDM). Results The levels of total IgA and IgG were increased in milk of HIV-infected mothers and stools of HIV-exposed children, indicating the activation of B cell-derived mucosal immunity. Breast milk samples as well as stool samples from HIV-negative and HIV-infected babies exposed to HIV by breast-feeding, contained high levels of HIV-specific antibodies, mainly IgG antibodies, less frequently IgA antibodies, and rarely IgM antibodies. Relative ratios of excretion by reference to lactoferrin calculated for HIV-specific IgA, IgG and IgM in stools of HIV-exposed children were largely superior to 1, indicating active production of HIV-specific antibodies by the intestinal mucosa. Antibodies to gp160 purified from pooled stools of HIV-exposed breastfed children inhibited the attachment of HIV-1NDK on HT29 cells by 63% and on MDM by 77%, and the attachment of HIV-1JRCSF on MDM by 40%; and the infection of MDM by HIV-1JRCSF by 93%.

Therapeutic HIV immunization is intended to induce new HIV-specific cellular immune responses and to reduce viral load, possibly permitting extended periods without antiretroviral drugs. A multigene, multi-subtype A, B, C HIV-DNA vaccine (HIVIS) has been used in clinical trials in both children and adults with the aim of improving and broadening the infected individuals’ immune responses. Despite the different country locations, different regimens and the necessary variations in assays performed, this is, to our knowledge, the first attempt to compare children’s and adults’ responses to a particular HIV vaccine. Ten vertically HIV-infected children aged 4–16 years were immunized during antiretroviral therapy (ART). Another ten children were blindly recruited as controls. Both groups continued their antiretroviral treatment during and after vaccinations. Twelve chronically HIV-infected adults were vaccinated, followed by repeated structured therapy interruptions (STI) of their antiretroviral treatment. The adult group included four controls, receiving placebo vaccinations. The HIV-DNA vaccine was generally well tolerated, and no serious adverse events were registered in any group. In the HIV-infected children, an increased specific immune response to Gag and RT proteins was detected by antigen-specific lymphoproliferation. Moreover, the frequency of HIV-specific CD8+ T-cell lymphocytes releasing perforin was significantly higher in the vaccinees than the controls. In the HIV-infected adults, increased CD8+ T-cell responses to Gag, RT and viral protease peptides were detected. No augmentation of HIV-specific lymphoproliferative responses were detected in adults after vaccination. In conclusion, the HIV-DNA vaccine can elicit new HIV-specific cellular immune responses, particularly to Gag antigens, in both HIV-infected children and adults. Vaccinated children mounted transient new HIV-specific immune responses, including both CD4+ T-cell lymphoproliferation

The HIV epidemic remains a major health challenge all over the world. In 2013, an estimated 35million people were living with HIV globally. Male circumcision is increasingly being adopted as a method of HIV prevention. WHO and UNAIDS have advised that male circumcision be added to current HIV interventions. Malawi is one of the countries hardest hit by HIV/AIDS with a prevalence rate of 11 % and male circumcision prevalence of 21.6 % in 2010. Prior to 2011, traditional male circumcision in Malawi was the dominant form of male circumcision, mainly for cultural and religious reasons. This paper looks at male circumcision as a prevention method against HIV by examining the relationship between male circumcision and HIV status among Malawian men. The data used were collected as part of the 2010 Malawi Demographic and Health Survey. The methodology used in the 2010 MDHS has been comprehensively described by the National Statistical Office of Malawi and ICF Macro. Our analysis is based on men aged 15-54 years who were tested for HIV and responded to questions on circumcision during the survey. Sixty one percent of the 7175 men interviewed in the MDHS, qualified for this analysis. The sample was weighted to ensure representativeness. Frequencies, cross-tabulations, univariate and multivariate logistic regressions were conducted. Differences in the prevalence of HIV infection among circumcised and uncircumcised men were determined with Chi-squared tests. There is no significant difference in HIV prevalence between circumcised (12 %) and uncircumcised men (10 %). Among circumcised men, age and number of lifetime partners are the dominant correlates of HIV status. Additionally, circumcised men who have had ritual sex are two times more likely (OR = 2.399) to be HIV+ compared to circumcised men who have never had ritual sex. This study has demonstrated that traditional male circumcision was not associated with HIV infection in pre-2010 Malawi. Among circumcised men, age and

Disclosure is an important component of comprehensive management of children living with HIV infection (CLHIV). Many parental concerns are barriers for disclosure in children and only few studies addresses children's perspective on these concerns. Our study aims to understand children's perspective on parental concerns for disclosure and assess the knowledge of HIV. A questionnaire-based cross-sectional study involving CLHIV between 10 and 18 years attending HIV clinic in southern India, was conducted. Data were collected by directly interviewing only the children after obtaining consent from parents/caregivers. Initial open-ended questions were asked to assess the disclosure status and only fully disclosed children were included. Out of 362 enrolled eligible children, the prevalence of full and partial disclosure was 36.7% and 24%, respectively. The mean age of disclosure was 10.4 years (SD ± 2.6) and non-parental family members in an informal setting were the most common source of disclosure (38.3%). Forty-six percentages of parents were unaware of their child's disclosure status. Only 2% had disclosed their status to others who were not part of their care. Among disclosed children, 33.8% became upset or sad upon knowing their status, 12% faced discrimination and 41.4% had complete knowledge about their illness. Though the prevalence of disclosure among CLHIV was high, a majority of them had incomplete knowledge about HIV infection. The parental concerns as reported in literature like the child is too young to disclose, concerns about coping, fear of stigma and discrimination and child disclosing to others were not expressed by children.

Explaining Antiretroviral Therapy Adherence Success Among HIV-Infected Children in Rural Uganda: A Qualitative Study

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

Rotavirus remains a leading cause of acute gastroenteritis in children worldwide with an estimated 2000 deaths each day in developing countries. Due to HIV/AIDS scourge in Kenya, it is possible that rotavirus-related gastroenteritis has been aggravated in adults. The Global Alliance for Immunizations has ranked rotavirus infection a priority for vaccine, and, to ensure its success, there is a need to document the local strain(s) circulating in different regions. A cross-sectional study was conducted to document human rotavirus group A serotypes in children below 5 years and HIV-infected adults in Viwandani slum in Nairobi, Kenya. A total of 260 (128 from children and 132 from HIV infected adults) fecal specimen samples were analyzed from August 2012 to July 2013. Screening for rotavirus was done by antigen based enzyme immune-sorbent assay (ELISA), Polyacrylamide gel electrophoresis (PAGE) was used to detect rotavirus electropherotypes and finally genotyping was done by RT-PCR using genotype-specific primer sets targeting VP4 and VP7 genes. Rotavirus was detected in 23% and 8% of children and adult, respectively. Prevalence was high in children of < 2 years and adults of > 48 years. Long electropherotypes accounted for 80% and 60% while short electropherotypes accounted for 20% and 40% in children and adult, respectively. The common globally distributed strains, G1 and G3, accounted for 60% detections while the unusual G9 strain accounted for 80% infection in adults. G1P[8] was the common genotypic combination in children, accounting for 40% infection, whereas G9 [P8] accounted for 60% of the infections in adults. This study shows the existence of strain diversity between rotavirus circulating in children and adults within this study group. It further shows that as currently constituted, the 2 vaccines recommended for rotavirus would cover the circulating strain in Viwandani slum. Finally, there is a need for continuous rotavirus strain surveillance in children and

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. 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. 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.

A community-based cross-sectional study among 554 Kolkata city street children assessed nontobacco substance use and sexual abuses along with human immunodeficiency virus (HIV)/ sexually transmitted infections (STIs) during 2007, using conventional cluster sampling technique for "hard-to-reach population" with a field-tested questionnaire and the collection of a blood sample for HIV and syphilis serology testing as a composite indicator of STIs. The reported prevalence of nontobacco substance use was 30%; 9% reported having been sexually abused. Some factors (age, lack of contact with family, orphan children, night stay at public place, etc.) were documented to be associated with substance use and sexual abuses. Seroprevalence of HIV was found to be 1% and that of STIs was 4%. This 1% HIV seroprevalence in street children is a matter of concern. Community-based intervention is necessary for them. The study's limitations are noted.

Kaposi Sarcoma Risk in HIV-Infected Children and Adolescents on Combination Antiretroviral Therapy From Sub-Saharan Africa, Europe, and Asia

PubMed Central

2016-01-01

Background. The burden of Kaposi sarcoma (KS) in human immunodeficiency virus (HIV)–infected children and adolescents on combination antiretroviral therapy (cART) has not been compared globally. Methods. We analyzed cohort data from the International Epidemiologic Databases to Evaluate AIDS and the Collaboration of Observational HIV Epidemiological Research in Europe. We included HIV-infected children aged <16 years at cART initiation from 1996 onward. We used Cox models to calculate hazard ratios (HRs), adjusted for region and origin, sex, cART start year, age, and HIV/AIDS stage at cART initiation. Results. We included 24 991 children from eastern Africa, southern Africa, Europe and Asia; 26 developed KS after starting cART. Incidence rates per 100 000 person-years (PYs) were 86 in eastern Africa (95% confidence interval [CI], 55–133), 11 in southern Africa (95% CI, 4–35), and 81 (95% CI, 26–252) in children of sub-Saharan African (SSA) origin in Europe. The KS incidence rates were 0/100 000 PYs in children of non-SSA origin in Europe (95% CI, 0–50) and in Asia (95% CI, 0–27). KS risk was lower in girls than in boys (adjusted HR [aHR], 0.3; 95% CI, .1–.9) and increased with age (10–15 vs 0–4 years; aHR, 3.4; 95% CI, 1.2–10.1) and advanced HIV/AIDS stage (CDC stage C vs A/B; aHR, 2.4; 95% CI, .8–7.3) at cART initiation. Conclusions. HIV-infected children from SSA but not those from other regions, have a high risk of developing KS after cART initiation. Early cART initiation in these children might reduce KS risk.

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. 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. 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. 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-trimoxazole in the health facilities was

Zimbabwe is one of the five countries worst affected by the HIV/AIDS pandemic with HIV infection contributing increasingly to childhood morbidity and mortality. Among the children born to HIV positive mothers participating in the PMTCT programme, 25% tested positive to HIV. We investigated factors associated with HIV infection among children born to mothers on the PMTCT programme. A 1:1 unmatched case-control study was conducted at Chitungwiza Hospital, Zimbabwe, 2008. A case was defined as a child who tested HIV positive, born to a mother who had been on PMTCT programme. A control was a HIV negative child born to a mother who had been on PMTCT programme. An interviewer-administered questionnaire was used to collect data on demographic characteristics, risk factors associated with HIV infection and immunization status. A total of 120 mothers were interviewed. Independent risk factors associated with HIV infection among children included maternal CD4 count of less than 200 during pregnancy [aOR = 7.1, 95% CI (2.6-17)], mixed feeding [aOR = 29, 95% CI (4.2-208)], being hospitalized since birth [aOR = 2.9, 95% CI (1.2-4.8)] whilst being exclusively breast fed for less than 6 months [aOR = 0.1 (95% CI 0.03-0.4)] was protective. HIV infection among children increased if the mother's CD4 count was ≤200 cells/μL and if the child was exposed to mixed feeding. Breastfeeding exclusively for less than six months was protective. We recommended exclusive breast feeding period for the first six months and stop breast feeding after 6 months if affordable, sustainable and safe.

The early serologic response of infants to infection with human immunodeficiency virus type 1 (HIV-1) is normally obscured by the presence of transplacentally acquired maternal HIV antibody. By measuring HIV antibody produced in vitro by lymphocytes isolated from peripheral blood of infants and children of HIV-1-infected mothers, we have been able to study the natural acquisition of humoral immunity to perinatal HIV-1 infection. One hundred ninety-seven infants of HIV-1-infected women were studied prospectively and longitudinally from birth. In the neonatal period, infected infants produced only small amounts of HIV-specific IgG antibodies to a restricted number of antigens. The amount of immunoglobulin to HIV-1 and the number of HIV-1 antigens recognized increased with age. After 6 months of life 85% of infected infants made detectable antibody to two or more viral proteins. Antibody to gp160 appeared first and was the most frequently found at all ages, followed by antibody to the envelope proteins gp120 and gp41. The amount of HIV antibody produced correlated positively with the percentage of CD4+ T lymphocytes in peripheral blood. This assay provides a method of studying the immunogenicity of vaccines against HIV-1 in HIV-1-infected infants and of assessing the effect of early therapeutic interventions on the humoral response to HIV-1.

Maternal weight loss during exclusive breastfeeding may influence the growth of exclusively breast-fed infants through impaired quality or quantity of breast milk. This study evaluated how maternal weight loss from 2 to 24 wk postpartum was related to infant weight and length gain in 1309 lactating HIV-infected mothers and their exclusively breast-fed infants. Malawian mother-infant pairs in the Breastfeeding, Antiretrovirals, and Nutrition Study were randomized with a 2 × 3 factorial design to a 2-arm nutritional intervention with a lipid-based nutrient supplement (LNS), meeting nutritional needs of lactation, or no LNS and a 3-arm antiretroviral (ARV) intervention (maternal, infant, or no ARV regimen). Linear regression models were used to relate maternal weight loss (weight loss vs. no weight loss) to infant weight and length gain from birth to 24 mo, stratifying by gender and controlling for maternal BMI at 2 wk (mean ± SD: 23.2 ± 3.0 kg/m2) and interacting maternal BMI with weight loss. In adjusted models, compared with daughters of women who did not lose weight, length and weight gain were lower in daughters whose mothers had a lower BMI at 2 wk postpartum coupled with the weight loss. For example, among mothers with an initial BMI of 18 kg/m2, daughters of those who lost weight gained less weight [β = −0.29 kg (95% CI: −0.53, −0.06)] and length [β = −0.88 cm (95% CI: −1.52, −0.23)] from birth to 24 wk than daughters of those who gained weight. Though effects were only observed in girls, suggesting possible gender differences in suckling and feeding behavior, these findings indicate that maternal weight loss with low energy reserves represents a risk factor for poor infant growth outcomes.

Objectives. We examined HIV-infected parents’ conversations about HIV prevention with their uninfected children, including what facilitated or hindered communication. Methods. Parents with HIV/AIDS (n = 90) who had children aged 10 to 18 years were recruited for a mixed method study from 2009 to 2010. Interviews assessed facilitators and barriers to discussing HIV prevention. A questionnaire identified the frequency and content of conversations, parental confidence level, and perceived importance of discussing preventive topics. Results. Eighty-one percent of parents reported “sometimes” or “often” communicating about HIV prevention. A subset of parents found these conversations difficult; 44% indicated their desire for support. Facilitators to communication included utilizing support, focusing on the benefits of talking, and having a previous relationship with one’s child. Barriers to discussions included fear of negative consequences, living in denial, and lacking a parental role model who discussed safer sex. Parents varied as to how they believed their HIV status affected communication. Those who did not disclose their HIV status to their children reported less frequent communication; self-efficacy partially mediated this relationship. Conclusions. Findings highlighted the need for communication skills training that support HIV-infected parents in their efforts to discuss HIV-related information with adolescents. PMID:23763390

Enzyme immunoassay was used to determine the presence of immunoglobulins class G to Toxocara canis antigens in the sera of children and adolescents (hereinafter referred to as children) with allergic and bronchopulmonary diseases from HIV infection and hepatitis B and C risk groups. A total of 422 dwellers of the Republic of Altai, including 144 subjects aged 1 to 17 years, were examined. Toxocara antibodies were found in 18.8 +/- 3.3% of the children and in 21.9 +/- 2.5% of the adults. The infection rate in children with bronchopulmonary and allergic diseases was 27.1 +/- 5.8 and 14.3 +/- 5.0%, respectively; that in the hepatitis B and C risk groups was 13.1 +/- 6.2%. The children (n = 6) from the HIV infection risk group were seronegative. The infection rate in the adults from the HIV infection and hepatitis risk group was 19.2 +/- 3.5 and 24.3 +/- 3.5%, respectively. Diagnostic antibody titers in the children and adults were determined in 9.0 +/- 2.3 and 8.3 +/- 1.6%, respectively. Immunological assays should be used to rule out toxocariasis in the examinees. If there are seropositive results, specific antiparasitic threatment should be performed.

To assess adequacy of vitamin C intake in HIV-infected children and adolescents; to evaluate serum levels of vitamin C and indicators of oxidative stress; to compare with the uninfected group; to correlate serum vitamin C with oxidative stress and associate them according to the reference values. Comparative cross-sectional study. Two groups of 27 children and adolescents each, aged between 3 to 19 years. Group 1 (G1) comprised individuals vertically infected with HIV seen at a regional outpatient clinic. Group 2 (G2) comprised invited individuals without history of HIV infection. The groups were matched for age, sex, and socioeconomic status. The following variables were analyzed: body mass index for age; micronutrient intake and consumption; and serum vitamin C, C-reactive protein (CRP), and albumin. The mean age was 12 years old. Most subjects were female (17, 63%), and there was prevalence of the economic class C (27, 50%). The most prevalent nutritional status was normal weight in 20 individuals (74.1%) in G1 and 21 (77.8%) in G2. The intake of vitamin C was significantly higher in G1 (p = 0.006; t = 2.987) according to the 24-hour dietary recall method. There were significant differences in serum vitamin C concentration between the groups, with a lower level in G1 (p = 0.000; t = -7.309). In relation to oxidative stress, values of CRP in G1 were significantly higher (p = 0.007; t = 2.958). There was no association between deficiency of vitamin, CRP, and albumin. Our findings show that HIV-infected individuals have low levels of vitamin C; however, this deficiency is not related to eating habits, since the intake of this nutrient was higher in this group than in the control group. HIV-infected individuals have specific characteristics that increase their oxidative stress, which is evidenced by increased CRP.

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

Background. In 2010, Zambia had a large measles outbreak, providing an opportunity to measure changes in measles serostatus following highly active antiretroviral therapy (HAART), exposure to measles virus, and revaccination among children infected with human immunodeficiency virus (HIV). Methods. A prospective cohort study of 169 HIV-infected Zambian children aged 9–60 months with a history of measles vaccination was conducted to characterize the effects of HAART and revaccination on measles immunoglobulin G (IgG) serostatus by enzyme immunoassay. Results. Prior to the measles outbreak, only 23% of HIV-infected children were measles IgG seropositive at HAART initiation. After adjusting for 6-month changes in baseline age and 5% changes in nadir CD4+ T-cell percentage, HAART was not associated with measles IgG seroconversion. However, 18 of 19 children seroconverted after revaccination. Eight children seroconverted during the outbreak without revaccination and were likely exposed to wild-type measles virus, but none were reported to have had clinical measles. Conclusions. Immune reconstitution after HAART initiation did not restore protective levels of measles IgG antibodies, but almost all children developed protective antibody levels after revaccination. Some previously vaccinated HIV-infected children had serological evidence of exposure to wild-type measles virus without a reported history of measles. PMID:23911708

In resource-limited settings, malnutrition is the major cause of death in young children, but the precise benefits of nutritional supplementation for HIV-infected children are not well understood. Two researchers reviewed studies conducted in low- or middle-income countries that involved macro- and micronutrient supplementation in HIV-infected individuals ≤18 years. Fifteen studies focused on micronutrients, including vitamin A, zinc, multivitamins, and multiple-micronutrient supplementation. The 8 macronutrient studies focused on ready-to-use foods (4 studies), spirulina, whey protein, general food rations, and F75 and F100 starter formulas. Vitamin A was associated with improved mortality rates, ranging from 28% to 63%. Multiple-micronutrient supplementations were not associated with improvement of measured health outcomes. Ready-to-use foods were associated with improvement in certain anthropometrics. Periodic vitamin A supplementation is associated with reduced mortality. Macronutrient supplementation is linked to improved anthropometrics. More research is needed to determine how nutritional supplementation benefits this particularly vulnerable population. © The Author(s) 2014.

Environmental enteropathy is subclinical inflammation of the upper gastrointestinal tract associated with reduced linear growth in developing countries. Usually investigators have used biopsy or a dual sugar absorption test to assess environmental enteropathy. Such tests are time and resource intensive, restricting their utility as screening methods. Serum endotoxin core antibody (EndoCab) concentration is a potential indicator of intestinal inflammation and integrity, and thus may be useful to predict environmental enteropathy. We analyzed the association of serum EndoCab levels versus linear growth and lactulose-mannitol assay results in 2-5 year old rural Malawian children. This was an observational study of 388 rural, asymptomatic Malawian children who had anthropometric measurements taken at least every 3 months since birth. In June and July 2011, dual sugar permeability tests were performed and serum samples were drawn for EndoCab assays. Pearson correlation, Student's t test and multivariable linear regression were used to compare ln EndoCab concentrations with height-for-age z scores (HAZ) at time of sampling and 3 months later. Identical analysis was also performed for ln EndoCab versus measurements from dual sugar permeability testing performed in conjunction with serum sampling. In a subgroup of children with anthropometric data in the months prior to serum sampling, Pearson correlation was used to estimate the relationship between ln EndoCab and recent linear growth. Ln EndoCab concentrations were not correlated with HAZ at time of measurement (B = -0.078, P = 0.14) nor change in HAZ over the subsequent 3 months HAZ (B = -0.018, P = 0.27). EndoCab concentration was not associated with %lactulose excretion (B < 0.001, P = 0.98) nor the lactulose:mannitol ratio (B = 0.021, P = 0.62). Subgroup analysis also did not reveal any significant association between EndoCab and recent growth. EndoCab titers were not correlated with measurements of growth or

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.

HIV-infected children require early initiation of antiretroviral therapy (ART) to ensure good outcomes. The aim was to investigate missed opportunities in childhood HIV diagnosis leading to delayed ART initiation. Baseline data were reviewed of all children aged <15 years referred over a 1-year period for ART initiation to the Kalafong Hospital HIV services in Gauteng, South Africa. Of the 250 children, one-quarter (24.5%) was of school-going age, 34.5% in the preschool group, 18% between 6 and 12 months old and 23% below 6 months of age (median age = 1.5 years [interquartile range 0.5-4.8]). Most children (82%) presented with advanced/severe HIV disease, particularly those aged 6-12 months (95%). Malnutrition was prominent and referrals were mostly from hospital inpatient services (61%). A structured caregiver interview was conducted in a subgroup, with detailed review of medical records and HIV results. The majority (≥89%) of the 65 interviewed caregivers reported good access to routine healthcare, except for postnatal care (26%). Maternal HIV-testing was mostly done during the second and third pregnancy trimesters (69%). Maternal non-disclosure of HIV status was common (63%) and 83% of mothers reported a lack of psychosocial support. Routine infant HIV-testing was not done in 66%, and inadequate reporting on patient-held records (Road-to-Health Cards/Booklets) occurred frequently (74%). Children with symptomatic HIV disease were not investigated at primary healthcare in 53%, and in 68% of families the siblings were not tested. One-third of children (35%) had a previous HIV diagnosis, with 77% of caregivers aware of these prior results, while 50% acknowledged failing to attend ART services despite referral. In conclusion, a clear strategy on paediatric HIV case finding, especially at primary healthcare, is vital. Multiple barriers need to be overcome in the HIV care pathway to reach high uptake of services, of which especially maternal reasons for not

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.

During human immunodeficiency virus (HIV) disease, chronic immune activation leads to T-cell exhaustion. PD-1 identifies "exhausted" CD8 T cells with impaired HIV-specific effector functions, but its role on CD4 T cells and in HIV-infected children is poorly understood. In a Kenyan cohort of vertically HIV-infected children, we measured PD-1+ CD4 T-cell frequencies and phenotype by flow cytometry and their correlation with HIV disease progression and immune activation. Second, in vitro CD4 T-cell proliferative and cytokine responses to HIV-specific and -nonspecific stimuli were assessed with and without PD-1 blockade. HIV-infected children have increased frequencies of PD-1+ memory CD4 T cells that fail to normalize with antiretroviral treatment. These cells are comprised of central and effector memory subsets and correlate with HIV disease progression, measured by viral load, CD4 percentage, CD4:CD8 T-cell ratio, and immune activation. Last, PD-1+ CD4 T cells predict impaired proliferative potential yet preferentially secrete the Th1 and Th17 cytokines interferon-γ and interleukin 17A, and are unresponsive to in vitro PD-1 blockade. This study highlights differences in PD-1+ CD4 T-cell memory phenotype and response to blockade between HIV-infected children and adults, with implications for potential immune checkpoint therapies. © The Author 2017.

HIV-1 R5 viruses are characterized by a large phenotypic variation, that is reflected by the mode of coreceptor use. The ability of R5 HIV-1 to infect target cells expressing chimeric receptors between CCR5 and CXCR4 (R5(broad) viruses), was shown to correlate with disease stage in HIV-1 infected adults. Here, we ask the question whether phenotypic variation of R5 viruses could play a role also in mother-to-child transmission (MTCT) of HIV-1 and pediatric disease progression. Viral isolates obtained from a total of 59 HIV-1 seropositive women (24 transmitting and 35 non transmitting) and 28 infected newborn children, were used to infect U87.CD4 cells expressing wild type or six different CCR5/CXCR4 chimeric receptors. HIV-1 isolates obtained from newborn infants had predominantly R5(narrow) phenotype (n = 20), but R5(broad) and R5X4 viruses were also found in seven and one case, respectively. The presence of R5(broad) and R5X4 phenotypes correlated significantly with a severe decline of the CD4+ T cells (CDC stage 3) or death within 2 years of age. Forty-three percent of the maternal R5 isolates displayed an R5(broad) phenotype, however, the presence of the R5(broad) virus was not predictive for MTCT of HIV-1. Of interest, while only 1 of 5 mothers with an R5X4 virus transmitted the dualtropic virus, 5 of 6 mothers carrying R5(broad) viruses transmitted viruses with a similar broad chimeric coreceptor usage. Thus, the maternal R5(broad) phenotype was largely preserved during transmission and could be predictive of the phenotype of the newborn's viral variant. Our results show that R5(broad) viruses are not hampered in transmission. When transmitted, immunological failure occurs earlier than in children infected with HIV-1 of R5(narrow) phenotype. We believe that this finding is of utmost relevance for therapeutic interventions in pediatric HIV-1 infection.

Increasing numbers of children with HIV are surviving to adolescence and encountering multiple clinical and social consequences of long-standing HIV infection. We aimed to investigate the association between HIV and disability, social functioning and school inclusion among 6- to 16-year-olds in Zimbabwe. HIV-infected children receiving antiretroviral therapy from a public-sector HIV clinic and HIV-uninfected children attending primary care clinics in the same catchment area were recruited. Standardised questionnaires were used to collect socio-demographic, social functioning and disability data. Multivariable logistic regression was used to assess the relationship between HIV status and disability and functioning. We recruited 202 HIV-infected and 285 HIV-uninfected children. There was no difference in age and gender between the two groups, but a higher proportion of HIV-infected children were orphaned. The prevalence of any disability was higher in HIV-infected than uninfected children (37.6% vs. 18.5%, P < 0.001). HIV-infected children were more likely to report anxiety (adjusted odds ratio (aOR) 4.4; 95% CI 2.4, 8.1), low mood (aOR 4.2; 2.1, 8.4) and difficulty forming friendships (aOR 14.8; 1.9, 116.6) than uninfected children. Children with HIV also reported more missed school days, repeating a school year and social exclusion in class. These associations remained apparent when comparing children with HIV and disability to those with HIV but no disabilities. Children with HIV commonly experience disabilities, and this is associated with social and educational exclusion. Rehabilitation and support services are needed to facilitate educational attainment and social participation in this group. © 2017 The Authors.

Nontyphoidal Salmonellae commonly cause invasive disease in African children that is often fatal. The clinical diagnosis of these infections is hampered by the absence of a clear clinical syndrome. Drug resistance means that empirical antibiotic therapy is often ineffective and currently no vaccine is available. The study objective was to identify risk factors for mortality among children presenting to hospital with invasive Salmonella disease in Africa. We conducted a prospective study enrolling consecutive children with microbiologically-confirmed invasive Salmonella disease admitted to Queen Elizabeth Central Hospital, Blantyre, in 2006. Data on clinical presentation, co-morbidities and outcome were used to identify children at risk of inpatient mortality through logistic-regression modeling. Over one calendar year, 263 consecutive children presented with invasive Salmonella disease. Median age was 16 months (range 0-15 years) and 52/256 children (20%; 95%CI 15-25%) died. Nontyphoidal serovars caused 248/263 (94%) of cases. 211/259 (81%) of isolates were multi-drug resistant. 251/263 children presented with bacteremia, 6 with meningitis and 6 with both. Respiratory symptoms were present in 184/240 (77%; 95%CI 71-82%), 123/240 (51%; 95%CI 45-58%) had gastrointestinal symptoms and 101/240 (42%; 95%CI 36-49%) had an overlapping clinical syndrome. Presentation at <7 months (OR 10.0; 95%CI 2.8-35.1), dyspnea (OR 4.2; 95%CI 1.5-12.0) and HIV infection (OR 3.3; 95%CI 1.1-10.2) were independent risk factors for inpatient mortality. Invasive Salmonella disease in Malawi is characterized by high mortality and prevalence of multi-drug resistant isolates, along with non-specific presentation. Young infants, children with dyspnea and HIV-infected children bear a disproportionate burden of the Salmonella-associated mortality in Malawi. Strategies to improve prevention, diagnosis and management of invasive Salmonella disease should be targeted at these children.

During anti-retroviral therapy (ART) HIV-1 persists in cellular reservoirs, mostly represented by CD4+ memory T cells. Several approaches are currently being undertaken to develop a cure for HIV-1 infection through elimination (or reduction) of these reservoirs. Few studies have so far been conducted to assess the possibility of reducing the size of HIV-1 reservoirs through vaccination in virologically controlled HIV-1-infected children. We recently conducted a vaccination study with a combined hepatitis A virus (HAV) and hepatitis B virus (HBV) vaccine in 22 HIV-1-infected children. We assessed the size of the virus reservoir, measured as total HIV-1 DNA copies in blood cells, pre- and postvaccination. In addition, we investigated by immunostaining whether the frequencies of CD4+ and CD8+ T cells and parameters of immune activation and proliferation on these cells were modulated by vaccination. At 1 month from the last vaccination dose, we found that 20 out of 22 children mounted a serological response to HBV; a majority of children had antibodies against HAV at baseline. The number of HIV-1 DNA copies in blood at 1 month postvaccination was reduced in comparison to baseline although this reduction was not statistically significant. A significant reduction of HIV-1 DNA copies in blood following vaccination was found in 12 children. The frequencies of CD4+ (naïve, effector memory) and CD8+ (central memory) T-cell subpopulations changed following vaccinations and a reduction in the activation and proliferation pattern of these cells was also noticed. Multivariate linear regression analysis revealed that the frequency of CD8+ effector memory T cells prior to vaccination was strongly predictive of the reduction of HIV-1 DNA copies in blood following vaccination of the 22 HIV-1-infected children. The results of this study suggest a beneficial effect of vaccination to reduce the size of virus reservoir in HIV-1-infected children receiving ART. A reduced frequency of

To assess children with retinopathy-positive cerebral malaria (CM) for neurocognitive sequelae. Participants were selected from an ongoing exposure-control study. Eighty-three Malawian children averaging 4.4 years of age and diagnosed with retinopathy-positive CM were compared to 95 controls. Each child was classified as delayed or not using age-based norms for the Malawi Developmental Assessment Tool (MDAT) for developmental delay on the total scale and for the domains of gross motor, fine motor, language and social skills. Groups were also compared on the Achenbach Child Behaviour Checklist (CBCL) (1.5-5 years). Children with retinopathy-positive CM were delayed, relative to the comparison group, on MDAT total development (P = 0.028; odds ratio or OR = 2.13), with the greatest effects on language development (P = 0.003; OR = 4.93). The two groups did not differ significantly on the Achenbach CBCL internalizing and externalizing symptoms total scores. Stepwise regression demonstrated that coma duration, seizures while in hospital, platelet count and lactate level on admission were predictive of assessment outcomes for the children with retinopathy-positive CM. Children who suffer retinopathy-positive CM at preschool age are at greater risk of developmental delay, particularly with respect to language development. This confirms previous retrospective study findings with school-age children evaluated years after acute illness. The MDAT and the Achenbach CBCL proved sensitive to clinical indicators of severity of malarial illness. © 2010 Blackwell Publishing Ltd.

A deletion of 32 base pairs in the CCR5 gene (delta32 CCR5) has been linked to resistance to HIV-1 infection in exposed adults and to the delay of disease progression in infected adults. To determine the role of delta32 CCR5 in disease progression of HIV-1 infected children born to seropositive mothers, we studied a polymerase chain reaction in 301 HIV-1 infected, 262 HIV-1 exposed-uninfected and 47 HIV-1 unexposed-uninfected children of Spanish and Italian origin. Infected children were further divided into two groups according to their rate of HIV-1 disease progression: rapid progressors who developed severe clinical and/or immunological conditions within the second year of life, and delayed progressors with any other evolution of disease. Among the latter were the long-term, non-progressors (LTNP) who presented with mild or no symptoms of HIV-1 infection above 8 years of age. Viral phenotype was studied for 45 delayed progressors. No correlation was found between delta32 CCR5 and mother-to-child transmission of HIV-1. However, the frequency of the deletion was substantially higher in LTNP, compared with delayed (p = 0.019) and rapid progressors (p = 0.0003). In children carrying the delta32 CCRS mutation, the presence of MT-2 tropic virus isolate was associated with a severe immune suppression (p = 0.028); whereas, the presence of MT-2 negative viruses correlated with LTNP (p = 0.010). Given the rapidity and simplicity of the assay, the delta32 CCR5 mutation may be a useful predictive marker to identify children with delayed disease progression who, consequently, may not require immediate antiretroviral treatment.

The purpose of this study was to evaluate the relationship between socio-demographic characteristics of caregivers and the oral health of their children infected with human immunodeficiency virus (HIV+) compared to a group of HIV-children and their caregivers. One hundred forty HIV+ and 140 healthy two- to five-year-old children and their caregivers who sought care at hospitals in Rio de Janeiro, Brazil, participated. Caregivers were interviewed for sociodemographic characteristics, and knowledge and attitudes regarding oral health. The decayed, missing and filled primary teeth (dmft) index was obtained for the children. Chi-square and Mann-Whitney tests were used (five percent significance level). Content analysis method was used for qualitative evaluation. Most interviewees were mothers (83.6 percent), did no work outside the home (69.3 percent), had low educational status (47.1 percent), and were born in the South/Southeast regions of Brazil (83.6 percent). The mean dmft was 3.48±3.14 for the HIV+ group and 1.02±1.00 for the healthy children. Oral care was reported as important by 54.1 percent of the caregivers. Those who didn't consider oral care important had never received information about oral health (P<0.01). Caregivers born in the North/Northeast regions took their children to the dentist less frequently than mothers born in other areas (P=0.02). Low educational status influenced the attitudes about oral health (P<0.01), irregular dental visits for the children (P<0.01), and the dmft index (P<0.01). Caregivers' low educational status and birthplace influenced the importance given to HIV+ children's oral health as well as the oral health knowledge and practices for both HIV+ and healthy children.

Achieving the Millennium Development Goals that aim to reduce malnutrition and child mortality depends in part on the ability of governments/policymakers to address nutritional status of children in general and those infected or affected by HIV/AIDS in particular. This study describes HIV prevalence in children, patterns of malnutrition by HIV status and determinants of nutritional status. The study involved 671 children aged 12-59 months living in the Agincourt sub-district, rural South Africa in 2007. Anthropometric measurements were taken and HIV testing with disclosure was done using two rapid tests. Z-scores were generated using WHO 2006 standards as indicators of nutritional status. Linear and logistic regression analyses were conducted to establish the determinants of child nutritional status. Prevalence of malnutrition, particularly stunting (18%), was high in the overall sample of children. HIV prevalence in this age group was 4.4% (95% CI: 2.79 to 5.97). HIV positive children had significantly poorer nutritional outcomes than their HIV negative counterparts. Besides HIV status, other significant determinants of nutritional outcomes included age of the child, birth weight, maternal age, age of household head, and area of residence. This study documents poor nutritional status among children aged 12-59 months in rural South Africa. HIV is an independent modifiable risk factor for poor nutritional outcomes and makes a significant contribution to nutritional outcomes at the individual level. Early paediatric HIV testing of exposed or at risk children, followed by appropriate health care for infected children, may improve their nutritional status and survival.

The study was conducted to assess the psychosocial adjustment of children affected by HIV/ AIDS in the eastern part of Ghana. Four groups of children (children who lost their parents to AIDS, children who lost their parents through other causes, children living with HIV infected, alive parents and the comparison children who were from the same community but did not have HIV/AIDS-related illness or death in their families) were interviewed on depressive symptoms, prosocial behaviours, hyperactivity, conduct and peer problems using the Strengths and Difficulties Questionnaire (SDQ). Orphans in general and children living with HIV-infected parents consistently demonstrated poorer psychosocial adjustment than comparison children in the same community. The findings underscore the urgency and importance of culturally and developmentally appropriate intervention efforts targeting psychosocial problems among children affected by AIDS and call for more exploration of risk and resilience factors, both individual and contextual, affecting the wellbeing of these children.

CCR5-using HIV-1 (R5 viruses) are usually isolated during acute infection from both adults and children. We have recently demonstrated that R5 viruses with a flexible use of CCR5 (called R5broad) can be detected in children close to birth and are predictive of a fast immunological failure. The aim of the present work was to investigate viral phenotype variation during disease progression in HIV-1 infected children, six slow and eight fast progressors. A total of 74 viral isolates obtained sequentially from 14 HIV-1 infected children were tested for their ability to infect U87.CD4 cells expressing a set of six different CCR5/CXCR4 chimeric receptors or wild-type coreceptors. The sensitivity of 35 R5 viruses to inhibition with the CC-chemokine RANTES (regulated upon activation, normal T-cell expressed and secreted) was evaluated in a peripheral blood mononuclear cells based assay. Viral evolution to R5broad or to R5X4 phenotype occurred with one exception, in all children, although at a different time point according to rate of disease progression. Immune deficiency in the children was significantly associated with the appearance of R5broad phenotype or R5X4 viruses. Analysis of the sensitivity to inhibition by RANTES revealed a significant correlation between the R5broad phenotype and an augmented resistance to this CC-chemokine. We demonstrate that the viral evolution to a more flexible CCR5-use is sufficient to explain the immunological failure in the absence of CXCR4 usage. These results warrant detailed analysis of the R5 phenotype in forthcoming clinical studies introducing CCR5 inhibitors for the treatment of pediatric HIV-1 infection.

Ghana has an estimated one million orphans, 250,000 are due to AIDS parental deaths. This is the first study that examined the impact of parental HIV/AIDS status and death on the mental health of children in Ghana. In a cross-sectional survey, 4 groups of 200 children (children whose parents died of AIDS, children whose parents died of causes other than AIDS, children living with parents infected with HIV/AIDS, and non-orphaned children whose parents are not known to be infected with HIV/AIDS) aged between 10 and 19 were interviewed on their hyperactivity, emotional, conduct, and peer problems using the Strengths and Difficulties Questionnaire. Children whose parents died of AIDS showed very high levels of peer problems [F (3,196) = 7.34, p < .001] whilst both orphaned groups scored similarly high on conduct problems [F (3, 196) = 14.85, p < .001]. Hyperactivity showed no difference and was very low in the entire sample. Emotional problems were very high in all the groups except among the non-orphaned children [F (3, 196) = 5.10, p < .001]. Orphans and children living with parents infected with HIV/AIDS are at heightened risks for emotional and behavioural disorders and that efforts to address problems in children affected by HIV/AIDS must focus on both groups of children. Parallel to this, researchers should see these findings as generated hypotheses (rather than conclusions) calling for further exploration of specific causal linkages between HIV/AIDS and children's mental health, using more rigorous research tools and designs.

Kidney disease is an important complication in HIV infected people, and this may be related to infection or antiretroviral therapy (ART). Our aim is to assess renal function in HIV infected paediatric patients, who may be particularly affected and are likely to take ART for longer than adults, and investigate the long term role of Tenofovir Disoproxil Fumarate (TDF) alone or co-administered with Ritonavir-boosted Protease Inhibitors (PI). Serum creatinine, phosphate and potassium levels, with estimated Glomerular Filtration Rate (eGFR), had been prospectively evaluated for 2 years in a cohort of HIV infected children and adolescents (age 9-18) on ART, and data analyzed according to the exposure to TDF or simultaneous TDF and PI. Forty-nine patients were studied (57% female, mean age 14). Sixty-three percent were treated with ART containing TDF (Group A), and 37% without TDF (Group B); 47% with concomitant use of TDF and PI (Group C) and 53% without this combination (Group D). The groups didn't differ for age, gender or ethnicity. The median creatinine increased in the entire cohort and in all the groups analyzed; eGFR decreased from 143.6 mL/min/1.73 m2 at baseline to 128.9 after 2 years (p = 0.006) in the entire cohort. Three patients presented a mild eGFR reduction, all were on TDF+PI. Phosphatemia decreased significantly in the entire cohort (p = 0.0003) and in TDF+PI group (p = 0.0128) after 2 years. Five patients (10%) developed hypophosphatemia (Division of Acquired Immune Deficiency AE grade 1 or 2), and four of them were on TDF+PI. Renal function decrease and hypophosphatemia occur over time in HIV infected children and adolescents on ART. The association with co-administration of TDF and PI appears weak, and further studies are warranted.

Air pollution exposure and HIV infection can each cause neurocognitive insult in children. The purpose of this study was to test whether children with combined high air pollution exposure and perinatal HIV infection have even greater risk of neurocognitive impairment. This was a cross-sectional study of HIV-uninfected unexposed (HUU) and HIV-infected children and their caregivers in Nairobi, Kenya. We used a detailed neuropsychological battery to evaluate neurocognitive functioning in several domains. We measured caregiver 24-h personal CO exposure as a proxy for child CO exposure and child urinary 1-hydroxypyrene (1-OHP), a biomarker for exposure to polycyclic aromatic hydrocarbons (PAHs). Median 24-h caregiver CO exposure was 6.1 and 3.7 ppm for 45 HIV-infected (mean age 6.6 years) and 49 HUU (mean age 6.7 years), respectively; 48.5% of HIV-infected and 38.6% of HUU had caregiver 24-h CO levels exceeding the WHO recommended level. Median 1-OHP exposure was 0.6 and 0.7 µmol/mol creatinine among HIV-infected and HUU children, respectively. HIV-infected children with high urinary 1-OHP (exceeding 0.68 µmol/mol creatinine) had significantly lower global cognition (p = 0.04), delayed memory (p = 0.01), and attention scores (p = 0.003). Among HUU children, urinary 1-OHP and caregiver 24-h caregiver CO were not significantly associated with neurocognitive function. Our findings suggest that combined chronic exposure to air pollutants and perinatal HIV infection may be associated with poorer neurocognitive outcomes. High prevalence of air pollution exposure highlights the need to reduce these exposures. PMID:29361707

Although the effect of highly active antiretroviral therapy (HAART) on growth in HIV-infected children is well known, the influence of prior nutritional and immunologic status on the response to HAART is not well documented. The aim of the present study was to determine the effects of HAART on nutritional and immunological status in HIV-infected children in the low-income country of Ethiopia. A multicenter, retrospective cohort study was conducted on HIV-infected children receiving antiretroviral therapy at the pediatric units of public hospitals in Addis Ababa (Black Lion, Zewditu, Yekatit 12 and ALERT hospitals), Ethiopia. Nutritional status was defined as stunting (height-for-age Z score [HAZ] <-2), wasting (weight-for-height Z score [WHZ] <-2), and underweight (weight-for-age Z score [WAZ] <-2). Multivariable logistic regression was used to analyze factors associated with treatment success and to establish whether growth (baseline nutritional status) in children predicts immunologic outcomes. In all, 556 HIV-infected children receiving HAART from January 2008 to December 2009 were included in this study. Over the 24-mo follow-up period, the study showed that the immunologic recovery of stunted and underweight children, regardless of their baseline nutritional status, responded equally to treatment. However, wasted children showed less immunologic recovery at the different follow-up visits. Predictors of positive shift in WHZ after 24 mo of follow-up were advanced disease stage (World Health Organization clinical stages 3 and 4) with odds ratio (OR), 0.25 (95% confidence interval [CI], 0.34-0.99; P = 0.045) and baseline severe underweight OR, 0.19 (95% CI, 0.09-0.56; P = 0.003). The independent predictors of positive shift of growth shift in WAZ over 24 mo were lower baseline age (<36 mo) with OR, 0.21 (95% CI, 0.04-0.90; P = 0.036) and baseline

Pediatric multidrug-resistant tuberculosis (MDR-TB) is complicated by difficult diagnosis, complex treatment, and high mortality. In South Africa, these challenges are amplified by human immunodeficiency virus (HIV) co-infection; however, evidence on treatment outcomes among co-infected children is limited. Using conventional and new pediatric definitions, to describe treatment outcomes and identify risk factors for unfavorable outcome and mortality in children aged <15 years with MDR-TB or extensively drug-resistant TB (XDR-TB) in KwaZulu-Natal, South Africa. Retrospective cohort study in a regional TB referral hospital. From January 2009 to June 2010, 84 children (median age 8 years, IQR 4-12) with MDR-TB (n = 78) or XDR-TB (n = 6) initiated treatment. Sixty-four (77%) were HIV-positive and 62 (97%) received antiretroviral therapy. Sixty-six (79%) achieved favorable treatment outcomes. Overall mortality was 11% (n = 9) at 18 months after initiation of treatment. Malnutrition (aOR 27.4, 95%CI 2.7-278.7) and severe radiographic findings (aOR 4.68, 95%CI 1.01-21.9) were associated with unfavorable outcome. New pediatric outcome definitions increased the proportion classified as cured. It is possible to successfully treat pediatric MDR-TB-HIV even in resource-poor settings. Malnutrition is a marker for severe TB-HIV disease, and is a potential target for future interventions in these patients.

The objective of this commentary is to review considerations for implementing routine viral load (VL) monitoring programmes for HIV-infected infants and children living in low- and middle-income countries (LMIC). Since 2013, the World Health Organization (WHO) guidelines recommend VL testing as the preferred monitoring approach for all individuals treated with ART in order to assess treatment response, detect treatment failure and determine the need to switch to a second-line regimen in a timely manner. More recently, WHO guidelines from 2016 identify HIV-infected infants and children as a priority group for routine VL monitoring. There are a number of reasons why HIV-infected infants and children should be prioritized for routine VL monitoring. Data from national VL monitoring programmes as well as systematic reviews and meta-analyses from LMIC indicate rates of viral suppression are lower for infants and children compared to adults. The number of antiretroviral drugs and palatable formulations suitable for young children are limited. In addition, emotional and developmental issues particular to children can make daily medication administration difficult and pose a challenge to adherence and achievement of sustained viral suppression. VL monitoring can be instrumental for identifying those in need of additional adherence support, reducing regimen switches and preserving treatment options. The needs of infants and children warrant consideration in all aspects of VL monitoring services. If capacity for paediatric venipuncture is not assured, platforms that accept dried blood spot specimens are necessary in order for infants and children to have equitable access. Healthcare systems also need to prepare to manage the substantial number of infants and children identified with elevated VL, including adherence interventions that are appropriate for children. Establishing robust systems to evaluate processes and outcomes of routine VL monitoring services and to support

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.

As access to paediatric antiretroviral therapy (ART) continues to improve in sub-Saharan Africa, a new historically specific cohort of HIV-perinatally infected children surviving into adolescent has emerged. Although remarkable successes have been made clinically in keeping this cohort alive and in reasonable health, their social support experiences are still unknown. The research being reported here sought to explore peer social support experiences of HIV-perinatally infected children in Harare, Zimbabwe. In this article, we draw on 56 repeat in-depth interviews (IDIs) conducted in three phases and two focus group discussions (FGDs) with HIV-infected children (11-13 years). Additional interviews were held with 10 carers. Study findings suggested that both children and carers perceive support groups as a safe social space for learning and acquiring HIV information as well as gaining confidence. Additionally, findings highlighted the importance of consistency of participation. Structural and personal barriers to access and participation in support group were also identified. We conclude that support groups are a useful resource for HIV-infected children and therefore should be supported by stable funding.

Background HIV-1 R5 viruses are characterized by a large phenotypic variation, that is reflected by the mode of coreceptor use. The ability of R5 HIV-1 to infect target cells expressing chimeric receptors between CCR5 and CXCR4 (R5broad viruses), was shown to correlate with disease stage in HIV-1 infected adults. Here, we ask the question whether phenotypic variation of R5 viruses could play a role also in mother-to-child transmission (MTCT) of HIV-1 and pediatric disease progression. Methodology/Principal Findings Viral isolates obtained from a total of 59 HIV-1 seropositive women (24 transmitting and 35 non transmitting) and 28 infected newborn children, were used to infect U87.CD4 cells expressing wild type or six different CCR5/CXCR4 chimeric receptors. HIV-1 isolates obtained from newborn infants had predominantly R5narrow phenotype (n = 20), but R5broad and R5X4 viruses were also found in seven and one case, respectively. The presence of R5broad and R5X4 phenotypes correlated significantly with a severe decline of the CD4+ T cells (CDC stage 3) or death within 2 years of age. Forty-three percent of the maternal R5 isolates displayed an R5broad phenotype, however, the presence of the R5broad virus was not predictive for MTCT of HIV-1. Of interest, while only 1 of 5 mothers with an R5X4 virus transmitted the dualtropic virus, 5 of 6 mothers carrying R5broad viruses transmitted viruses with a similar broad chimeric coreceptor usage. Thus, the maternal R5broad phenotype was largely preserved during transmission and could be predictive of the phenotype of the newborn's viral variant. Conclusions/Significance Our results show that R5broad viruses are not hampered in transmission. When transmitted, immunological failure occurs earlier than in children infected with HIV-1 of R5narrow phenotype. We believe that this finding is of utmost relevance for therapeutic interventions in pediatric HIV-1 infection. PMID:18820725

Psychiatric disorders such as bipolar disorder, schizophrenia and depression have long been associated with risk behaviors for HIV, hepatitis C virus (HCV) and hepatitis B virus (HBV). The US prison population is reported to have elevated rates of HIV, hepatitis and most psychiatric disorders. This study examined the association of six major psychiatric disorders with HIV mono-infection, HIV/HCV co-infection and HIV/HBV co-infection in one of the nation's largest prison populations. The study population consisted of 370,511 Texas Department of Criminal Justice inmates who were incarcerated for any duration between January 1, 2003 and July 1, 2006. Information on medical conditions and sociodemographic factors was obtained from an institution-wide electronic medical information system. Offenders diagnosed with HIV mono-infection, HIV/HCV, HIV/HBV and all HIV combined exhibited elevated rates of major depression, bipolar disorder, schizophrenia, schizoaffective disorder, non-schizophrenic psychotic disorder and any psychiatric disorder. In comparison to offenders with HIV mono-infection, those with HIV/HCV co-infection had an elevated prevalence of any psychiatric disorder. This cross-sectional study's finding of positive associations between psychiatric disease and both HIV infection and hepatitis co-infection among Texas prison inmates holds both clinical and public health relevance. It will be important for future investigations to examine the extent to which psychiatric disorders serve as a barrier to medical care, communication with clinicians and adherence to prescribed medical regimens among both HIV-mono-infected and HIV/hepatitis-co-infected inmates.

To define age at entry into Tanner stages in children with perinatal HIV-1 infection. Multicentre longitudinal study including 212 perinatally HIV-1-infected children (107 girls and 105 boys) followed-up during puberty (from 8 and 9 years onwards in girls and boys, respectively). Healthy children (843 girls and 821 boys) provided reference percentiles. P2 or B2 stages in girls and P2 or G2 stages in boys defined onset of puberty. The cumulative probability [95% confidence limit (CI)] of entry into each stage at different ages was estimated by the Kaplan-Meier product-limit method; differences were evaluated by log rank test. Relationships were tested using the Spearman's rank correlation coefficient. Ages of girls [years (95%CI)] at P2 [12.9 (12.6-13.2)], P3 [13.4 (13.0-13.8)], P4 [14.6 (14.0-15.2)], B2 [12.7 (12.2-13.2)], B3 [13.3 (12.8-14.0)] and B4 [14.6 (14.0-15.2)] stages were > 97th percentile (> or = 21 month delay) of controls. Ages of boys [years (95%CI)] at P2 [12.6 (12.1-13.1)], P3 [13.9 (13.4-14.4)], P4 [14.9 (14.2-15.6)], G2 [12.1 (11.5-12.7)], G3 [13.6 (13.1-14.1)] and G4 [14.9 (14.1-15.7)] stages were at the 75-97th percentiles (< or = 15 month delay). Age at onset of puberty was not related to clinical and immunological condition, antiretroviral treatment, weigh for height and age at onset of severe disease or immune suppression. Perinatal HIV-1 infection interferes with sexual maturation. The mechanisms by which this occurs should be elucidated and intervention strategies designed. Intervention could save much psychological distress, since associated linear growth failure can exacerbate adolescents' feelings of being different and unwell.

Artemisinin-based combination therapies (ACTs) are highly efficacious and safe, but data from human immunodeficiency virus (HIV)-infected children concurrently receiving antiretroviral therapy (ART) and ACTs are limited. We evaluated 28-day outcomes following malaria treatment with artemether-lumefantrine (AL) or dihydroartemisinin-piperaquine (DP) in 2 cohorts of HIV-infected Ugandan children taking various ART regimens. In one cohort, children <6 years of age were randomized to lopinavir/ritonavir (LPV/r) or nonnucleoside reverse transcriptase inhibitor-based ART and treated with AL for uncomplicated malaria. In another cohort, children <12 months of age were started on nevirapine-based ART if they were eligible, and randomized to AL or DP for the treatment of their first and all subsequent uncomplicated malaria episodes. There were 773 and 165 treatments for malaria with AL and DP, respectively. Initial response to therapy was excellent, with 99% clearance of parasites and <1% risk of repeat therapy within 3 days. Recurrent parasitemia within 28 days was common following AL treatment. The risk of recurrent parasitemia was significantly lower among children taking LPV/r-based ART compared with children taking nevirapine-based ART following AL treatment (15.3% vs 35.5%, P = .009), and those treated with DP compared with AL (8.6% vs 36.2%, P < .001). Both ACT regimens were safe and well tolerated. Treatment of uncomplicated malaria with AL or DP was efficacious and safe in HIV-infected children taking ART. However, there was a high risk of recurrent parasitemia following AL treatment, which was significantly lower in children taking LPV/r-based ART compared with nevirapine-based ART. © The Author 2014.
