Abstract
Young people with perinatally acquired HIV are routinely problematized in the research literature as inadequately equipped to manage transition to adolescent sexuality and adult clinical care without comprehensive interventions, partly because of challenges associated with adolescence itself, and partly because of neurocognitive and psychosocial dysfunctions commonly attributed to these children. However, little is actually known about this population, given their recent emergence in the HIV epidemic. Using critical discourse analysis, we argue that several problematic assumptions operate in this literature, hampering the objective of understanding these young people. Our analysis can contribute to a reframing of future research on HIV-positive adolescents, by encouraging greater attunement to the experiences of the adolescents themselves and to the discursive meanings that underpin research agendas, so that different and more productive questions can be asked and answered.

Abstract
BACKGROUND Despite the burden of human immunodeficiency virus (HIV) disease in Southern Africa, there have been few reports of HIV-related nephropathy in children. This study outlines the spectrum of HIV-1-related kidney diseases of children in KwaZulu-Natal, South Africa. METHODS A review of the clinical presentation, laboratory and histopathological findings of children diagnosed with HIV-related nephropathy. RESULTS Forty-nine out of 71 children (1-16 years old) with HIV-1 related nephropathy underwent kidney biopsy. The most common histopathological finding was focal segmental glomerulosclerosis (FSGS), which was present in 32 (65.3%) children; 13 (26.5%) having collapsing glomerulopathy and 19 (38.8%) classic FSGS. The majority of patients showed haematological (86.4%) and electrolyte abnormalities (69.4%). Renal impairment was present in 41% of patients on initial presentation. However, end-stage kidney disease was present in only 4% of these patients. All patients were treated with highly active anti-retroviral therapy (HAART), the majority (79.6%) showed decreased proteinuria with 38.8% having complete remission. CONCLUSIONS This study, one of the largest series of children reported from Africa, demonstrates that nephrotic syndrome due to HIV-associated nephropathy (HIVAN) is the commonest presentation of HIV-related nephropathy in childhood. Highly active anti-retroviral therapy in combination with angiotensin-converting enzyme antagonists is highly effective in decreasing proteinuria and preserving renal function.

Abstract
OBJECTIVES To measure proinflammatory cytokines (PIC) in HIV-infected children beginning or changing antiretroviral therapy (ART), evaluating associations with virologic, immunologic, serum lipid, growth, and body composition measures, markers of growth hormone action and glucose metabolism. METHODS Forty-nine prepubertal HIV-infected children had measurements of viral load (VL), CD4 lymphocyte count and percentage, serum lipids, apolipoprotein AI/B, IGF-1, IGFBP-1, and IGFBP-3, anthropometry, bioelectrical impedance analysis, TNF-α, IL-1 β, and IL-6 at baseline and 48 weeks of ART. RESULTS Baseline levels were detectable (>0.1 pg/mL) for IL-1 β in 28 of 48, and for TNF-α and Il-6 in all 49 children. TNF-α decreased with ART (P < 0.001) and IL-6 demonstrated a similar trend (P = 0.065). Children with 48-week VL <400 copies/mL had greater declines in TNF-α (mean 45%) than subjects with higher VL (5%; P = 0.009). Each 10% improvement in CD4% was associated with 26% lower TNF-α (P = 0.002) and 31% lower IL-6 (P = 0.016). Greater reductions in TNF-α were associated with lower total/HDL cholesterol ratio (P = 0.003) at week 48. CONCLUSIONS In HIV-infected children initiating or changing ART, PIC were detectable at baseline and decreased over 48 weeks. Better immunologic responses were associated with greater reductions in TNF-α and IL-6. Reductions in TNF-α were associated with improved total/HDL cholesterol ratio.

Abstract
OBJECTIVES The aim of the study was to describe growth and body composition changes in HIV-positive children after they had initiated or changed antiretroviral therapy (ART) and to correlate these with viral, immune and treatment parameters. METHODS Ninety-seven prepubertal HIV-positive children were observed over 48 weeks upon beginning or changing ART. Anthropometry and bioelectrical impedance analysis results were compared with results from the National Health and Nutrition Examination Survey 1999-2002 (NHANES) to generate z-scores and with results for HIV-exposed, uninfected children from the Women and Infants Transmission Study (WITS). Multivariate analysis was used to evaluate associations between growth and body composition and disease parameters. RESULTS All baseline lean and fat mass measures were below those of controls from NHANES. Weight, height and fat free mass (FFM) index (FFM/height(2)) z-scores increased over time (P = 0.004, 0.037 and 0.027, respectively) and the waist:height ratio z-score decreased (P = 0.045), but body mass index and per cent body fat z-scores did not change. Measures did not increase more than in uninfected WITS controls. In multivariate analysis, baseline height, mid-thigh circumference and FFM z-scores related to CD4 percentage (P = 0.029, P = 0.008 and 0.020, respectively) and change in FFM and FFM index z-scores to CD4 percentage increase (P = 0.010 and 0.011, respectively). Compared with WITS controls, baseline differences in height and mid-thigh muscle circumference were also associated with CD4 percentage. Case-control differences in change in both subscapular skinfold (SSF) thickness and the SSF:triceps skinfold ratio were inversely associated with viral suppression. No measures related to ART class(es) at baseline or over time. CONCLUSIONS In these HIV-positive children, beginning or changing ART was associated with improved growth and lean body mass (LBM), as indicated by FFM index. Height and LBM related to CD4 percentage at baseline and over time. Altered fat distribution and greater central adiposity were associated with detectable virus but not ART class(es) received.

Abstract
Adherence to antiretroviral regimens continues to be a significant problem in HIV-infected individuals facing a lifetime of therapy. Youth who were infected through perinatal transmission enter into adolescence often with a history of multiple medication regimens. Thus, adherence can be a particularly important issue in these young people, as medication options can often be limited. This was a cross-sectional, observational study to determine the prevalence of personal barriers to adherence and to identify associations among the following barriers in subjects 12 to 24 years old: mental health barriers, self-efficacy and outcome expectancy, and structural barriers. Among the 368 study participants, 274 (74.5%) were adherent and 94 (25.5%) were nonadherent to highly active antiretroviral therapy (HAART). No significant differences were found between adherent and nonadherent subjects according to mental health disorders. Adherence was associated with some but not all structural barriers. Both self-efficacy and outcome expectancy were significantly higher in adherent versus nonadherent subjects (p < 0.0001). In subjects with low self-efficacy and outcome expectancy, adherence differed according to the presence or absence of either mental health or structural barriers, similar to findings in behaviorally- infected adolescents. Interventions that address the breadth and clustering of adherence barriers in adolescents are needed to have the maximum chance for positive effects.

Abstract
OBJECTIVES The implementation of rapid HIV-1 testing for women in labor with undocumented HIV status is an essential tool for the prevention of perinatal HIV transmission. Unfortunately, practices of rapid HIV testing for women with unknown HIV status in labor have not been studied. We evaluated the utilization of rapid HIV testing prior to and after implementation of CDC recommendations as well as factors that may affect the utilization rate. DESIGN STUDY participants were randomly selected from all deliveries (n = 2,359) six months prior to (n = 422) and after (n = 403) hospital implementation of the rapid HIV testing protocol. We reviewed prenatal and labor/delivery records to identify HIV testing history during pregnancy and HIV status at admission; we studied Rapid HIV testing utilization in respect to the implementation of the CDC recommendation; and we analyzed maternal sociodemographic and perinatal factors in association with rapid HIV testing utilization. RESULTS Unknown HIV status at admission was recorded for 22.0% of women who gave birth prior to, and 18.1% after, implementation of the hospital policy due to either no offering or no acceptance of HIV testing during the pregnancy. Among those eligible for rapid HIV testing, 7.6% were tested prior to, and 9.6% were tested after, implementation of the new policy. As compared with tested women, women not tested were more likely to be white, married, and to have received prenatal primary care from a private physician. CONCLUSIONS We found that low utilization of rapid HIV-1 testing for women in labor with undocumented HIV status is mostly associated with the sociodemographic inequality of the population of women served. Continuous education of health care providers and a systematic review of rapid HIV testing utilization in the hospital setting are needed in order to achieve successful implementation of the current CDC recommendations.

Abstract
OBJECTIVES To describe insulin-like growth factor-1 (IGF-1) and insulin-like growth factor-1-binding protein-1 (IGFBP-1) and IGFBP-3 in HIV+ children before and after initiating or changing antiretroviral therapy and to evaluate association of growth and body composition to growth factors at baseline and over time. METHODS Ninety-seven prepubertal HIV+ children aged 1 month to younger than 13 years were observed over 48 weeks after beginning or changing antiretroviral therapy. Serum IGF-1, IGFBP-1, and IGFBP-3 were measured and compared with age- and sex-specific norms. Anthropometric measures were compared as follows: subjects vs matched children from (a) the National Health and Nutrition Examination Survey to generate z scores and (b) HIV-exposed, uninfected children from Women and Infants Transmission Study; and subjects with normal vs abnormal IGF-1 and IGFBP concentrations at baseline. Anthropometric changes were compared for children whose IGF-1 level normalized vs remaining subjects. Multivariate analysis adjusting for sex, race, and baseline age evaluated associations between anthropometry and IGF-1 and IGFBP concentrations. RESULTS In multivariate analysis, lower baseline IGF-1 and IGFBP-3 were associated with lower mean weight, height, mid-arm muscle circumference, and mid-thigh circumference z scores. Twenty-four percent of children had a low IGF-1 level at baseline, 50% of whom normalized IGF-1 on study. Children whose IGF-1 normalized had greater increases in mean mid-arm muscle circumference z score (1.00 vs -0.03, P = 0.029), but a trend toward lesser mean height increase (P = 0.082) than remaining subjects. Likewise, in comparison to controls from Women and Infants Transmission Study, mean mid-arm muscle circumference also increased more in children whose IGF-1 normalized (P = 0.024) but mean height changed less (P = 0.003). Fifty-five percent of children had elevated IGFBP-1 at baseline, 69% of whom normalized. CONCLUSIONS IGF-1 increases and IGFBP-1 decreases in HIV-infected children upon initiation or change in antiretroviral therapy. Improved muscle mass, but not linear growth, is associated with normalized IGF-1 concentration. These findings suggest that IGF-1 may merit evaluation as a potential therapeutic strategy to improve lean body mass in HIV-infected children.

Abstract
OBJECTIVE To report the results of a systematic review of randomized controlled trials (RCTs) of psychological interventions for children and adolescents undergoing needle-related procedures. METHODS A variety of cognitive-behavioral psychological interventions for managing procedural pain and distress in children and adolescents between 2 and 19 years of age were examined. Outcome measures included pain and distress as assessed by self-report, observer report, behavioral/observational measures, and physiological correlates. RESULTS Twenty-eight trials met the criteria for inclusion in the review and provided the data necessary for pooling the results. Together, the trials included 1,039 participants in treatment conditions and 951 in control conditions. The largest effect sizes for treatment improvement over control conditions were found for distraction, combined cognitive-behavioral interventions, and hypnosis, with promising but limited evidence for several other psychological interventions. CONCLUSIONS Recommendations for conducting future RCTs are provided, and particular attention to the quality of trial design and reporting is highlighted.

Abstract
The development of chronic lung disease is common in HIV-infected children. The spectrum of chronic HIV-associated lung disease includes lymphocytic interstitial pneumonia (LIP), chronic infections, immune reconstitution inflammatory syndrome (IRIS), bronchiectasis, malignancies, and interstitial pneumonitis. Chronic lung disease may result from recurrent or persistent pneumonia due to bacterial, mycobacterial, viral, fungal or mixed infections. In high tuberculosis (TB) prevalence areas, M. tuberculosis is an important cause of chronic respiratory illness. With increasing availability of highly active antiretroviral therapy (HAART) for children in developing countries, a rise in the incidence of IRIS due to mycobacterial or other infections is being reported. Diagnosis of chronic lung disease is based on chronic symptoms and persistent chest X-ray changes but definitive diagnosis can be difficult as clinical and radiological findings may be non-specific. Distinguishing LIP from miliary TB remains a difficult challenge in HIV-infected children living in high TB prevalence areas. Treatment includes therapy for specific infections, pulmonary clearance techniques, corticosteroids for children with LIP who are hypoxic or who have airway compression from tuberculous nodes and HAART. Children who are taking TB therapy and HAART need adjustments in their drug regimes to minimize drug interactions and ensure efficacy. Preventative strategies include immunization, chemoprophylaxis, and micronutrient supplementation. Early use of HAART may prevent the development of chronic lung disease.

Abstract
Children and youth with perinatally acquired HIV infection are living longer because of improved drug therapies, but they may be at risk for poor health-related quality of life (HRQOL) outcomes because of nondisease factors. Families affected by HIV disease are more likely to experience major negative life events (NLEs). The effects of NLEs, shown to impact HRQOL in children with other chronic illnesses, have not been evaluated in children with HIV infection. The primary objective of this study was to determine if NLEs occurring in the previous 12 months were associated with increased risk for poorer outcomes in three measures of HRQOL (health perception, behavior problems, and symptom distress) in a cohort of children and youth with HIV infection. The authors conducted a cross-sectional analysis of data determined in 1999 from 1,018 children and youth 5 to 21 years of age enrolled in a longitudinal follow-up study. Multivariate logistic regressions estimated the odds for worse HRQOL outcomes. Children and youth with one or more NLEs had significantly lower health perceptions, more behavior problems, and greater symptom distress than children with no reported NLEs. The occurrence of NLEs may present a significant nondisease risk for diminished HRQOL among children and youth challenged by HIV disease. Nursing efforts to support these younger patients and their families sustaining major family disruption caused by NLEs may improve overall health outcomes in this vulnerable population.

Abstract
Using a semi-structured survey and convenience sample of pregnant/recently delivered Hispanic (n = 453) and non-Hispanic (n = 904) women in four California counties, this study compared rates of timely prenatal care (PNC) initiation, HIV test counseling, test offering, and test acceptance in PNC between Hispanic and non-Hispanic women. Hispanic women were less likely to report timely PNC initiation (69.3% vs. 80.4%, p < .0001), receiving test offer (69.5% vs. 76.7%, p = .002), and ever having been tested (77.3% vs. 87.9%, p < .0001) than non-Hispanic women. Hispanic women were more likely to report not knowing where to go (p = .04) and having no insurance (p < .001), transportation (p = .001), and child care (p = .007) as reasons for late PNC start. Both Hispanic and non-Hispanic women most commonly accepted a test offer for their health/health of their baby; Hispanic women were more likely to accept based on doctor/nurse recommendation (80.1% vs. 62.7%, p < .001). A quarter of Hispanic and non-Hispanic women reported they didn't feel they had a choice or that test was done automatically. Efforts to improve perinatal HIV prevention opportunities for all women in California are required. Furthermore, Hispanic women may have disparities in receipt of prenatal care and HIV test offer that need additional attention.

Abstract
BACKGROUND Our aim was to study the clinical profile of pediatric patients admitted with HIV infection. METHODS The prospective study was conducted from January 2000 to October 2001 at a tertiary care referral teaching hospital in Mumbai, India. Admitted in-patients (aged 1 month to 12 years) detected to be HIV-positive (on triple ELISA test) were enrolled in the study. HIV status of patients < 18 months of age was confirmed by DNA-PCR testing. Demographic data, clinical features, investigations and outcome were recorded in a pre-designed proforma. RESULTS Fifty HIV-positive children (31 males and 19 females; M:F = 1.6:1) were enrolled. Thirty cases were completely immunized, 9 were partially immunized while 11 were not immunized. Forty-two were perinatally infected, while eight cases were infected via blood transfusion (patients with thalassemia major on chronic transfusion therapy). Clinical features at presentation in 42 symptomatic cases included protein-energy malnutrition (90%), fever > 1 month (50%), weight loss > 1 month (50%), persistent generalized lymphadenopathy (24%) and skin manifestations (79%). The gastrointestinal (62%) and respiratory (52%) were the most commonly involved organ systems. Opportunistic infections noted included tuberculosis (19 cases), candidiasis (6 cases), Pneumocystis carinii pneumonia (4 cases), herpes zoster (3 cases) and giardiasis (1 case). Six patients died (mortality, 14%). CONCLUSIONS Perinatal transmission is the most common mode of acquiring HIV in the pediatric age group. Most patients have protein-energy malnutrition. Tuberculosis is common in HIV-infected Indian children. Patients with HIV-encephalopathy have a poor outcome.

Abstract
A double scenario characterizes the epidemiology of HIV infection in children. In countries where highly active antiretroviral therapy (HAART) is available, the pattern of HIV infection is evolving into that of a chronic disease, for which control strictly depends on patients' adherence to treatment. In developing countries with no or limited access to HAART, AIDS is rapidly expanding and is loaded with a high fatality ratio, due to the combined effects of malnutrition and opportunistic infections. The digestive tract is a target of the disease in both settings. Opportunistic infections play a major role in children with severe immune impairment, with Cryptosporidium parvum being the leading agent of severe diarrhea. Several therapeutic approaches are effective in reducing fecal output, but the eradication of the parasite is rarely obtained. Other opportunistic infections may induce severe and protracted diarrhea, including atypical mycobacteria and cytomegalovirus. Diagnosis of diarrhea should be individually tailored based on presenting symptoms and risk factors. A stepwise approach is effective in limiting patient discomfort and minimizing the costs of investigations, starting with microbiologic investigation and proceeding with endoscopy and histology. Aggressive treatment of infectious diarrhea is required in severely immunocompromised children. However, antiretroviral therapy prevents the development of severe cryptosporidiosis. The liver and pancreas are also target organs in HIV infection, although functional failure is rare. The digestive-absorptive functions are impaired, with steatorrhea, nutrient malabsorption, and increased permeability occurring in 20-70% of children. Intestinal dysfunction contributes to growth failure and further immune derangement, leading to wasting, the terminal stage of AIDS. Nutritional management is crucial in HIV-infected children and is based on aggressive nutritional rehabilitation through enteral or parenteral routes and micronutrient supplementation.HIV may play a direct enteropathogenic role and is implicated in both diarrhea and intestinal dysfunction. This explains the efficacy of antiretroviral therapy in inducing remission of diarrhea and restoring intestinal function. Gastrointestinal side effects of antiretroviral drugs are increasingly observed; they are often mild and transient. Severe reactions are rare but require the withdrawal of drugs. In conclusion, severe enteric infections and intestinal dysfunction characterize the intestinal involvement of HIV infection. This is more common in, but not limited to, children who do not receive effective antiretroviral therapy. Diagnostic approaches include microbiologic and morphologic examinations and assessment of digestive processes, but immunologic and virologic data should be also carefully considered. Treatment is based upon specific anti-infectious drugs, antiretroviral therapy, and nutritional rehabilitation.

Abstract
In 1984, physicians in New York and Miami reported HIV-infected adult patients with heavy proteinuria and rapid progression to end-stage renal disease. These patients showed large edematous kidneys with a combination of focal segmental glomerulosclerosis (FSGS) and tubulointerstitial lesions. This renal syndrome, named HIV-associated nephropathy (HIVAN), was found predominantly in African Americans. Subsequent studies confirmed the presence of HIVAN in children, who frequently develop nephrotic syndrome in association with FSGS and/or mesangial hyperplasia with microcystic tubular dilatation. Since then, substantial progress has been made in our understanding of the etiology and pathogenesis of HIVAN. This article reviews 20 years of research into the pathogenesis of HIVAN and discusses how these concepts could be applied to the treatment of children with HIVAN. HIV-1 infection plays a direct role in the pathogenesis of childhood HIVAN, at least partially by affecting the growth and differentiation of glomerular and tubular epithelial cells and enhancing the renal recruitment of infiltrating mononuclear cells and cytokines. An up-regulation of renal heparan sulfate proteoglycans seems to play a relevant role in this process, by increasing the recruitment of heparin-binding growth factors (i.e., FGF-2), chemokines, HIV-infected cells, and viral proteins (i.e., gp120, Tat). These changes enhance the infectivity of HIV-1 in the kidney and induce injury and proliferation of intrinsic renal cells. Highly active anti-retroviral therapy (HAART) appears to be the most promising treatment to prevent the progression of childhood HIVAN. Hopefully, in the near future, better education, prevention, and treatment programs will lead to the eradication of this fatal childhood disease.

Abstract
BACKGROUND The relationships among weight and height growth, viral load and survival in HIV-infected children remain unclear. OBJECTIVES To determine whether weight or height growth velocity independently predicts survival and to investigate associations of weight, height and head circumference growth velocities with viral loads in symptomatic HIV-infected children. METHODS We analyzed data from a prospective antiretroviral study utilizing clinical endpoints (PACTG 152). Viral load [log(RNA PCR)] and anthropometric measures 12 weeks before and after viral load measures were available in 494 of 831 children. Interval changes during 24 weeks in z-scores for weight-for-age (DeltaWAZ), height-for-age (DeltaHAZ) and head circumference-for-age (DeltaHCZ) were used as growth velocity surrogates. Logistic regression determined whether DeltaWAZ and/or DeltaHAZ correlated with survival when age, viral load and CD4+ cell count were controlled. Bivariate analysis assessed correlation among viral load and DeltaWAZ, DeltaHAZ and/or DeltaHCZ. RESULTS Survival related significantly to height growth velocity (P = 0.03, n = 434) but not to weight growth velocity (P = 0.84, n = 446) or head circumference growth velocity (P = 0.67, n = 148). Viral load was not significantly associated with changes in weight-, height-, or head circumference-for-age z scores (P = 0.86, n = 235; P = 0.07, n = 226; and P = 0.09, n = 165, respectively) in children <30 months of age or with changes in weight- or height-for-age z scores (P = 0.27, n = 259; P = 0.11, n = 251) in older children. CONCLUSIONS Height growth velocity predicted survival independently of age, viral load and CD4+ cell count. Weight, height and head circumference growth velocities were not significantly associated with viral load in symptomatic HIV-infected children in this large prospective trial of nucleoside reverse transcriptase therapy.

Abstract
BACKGROUND With implementation of highly active antiretroviral therapy during 1995 through 1999, deaths reported in adults with HIV infection decreased 67%, and the proportions of those accompanied by various opportunistic infections decreased, whereas their proportions with possibly unrelated conditions (e.g. diseases of liver, kidneys and heart) increased. OBJECTIVE To examine changes among deaths of children with HIV infection. METHODS We analyzed multiple-cause death certificate data with any mention of HIV infection for all US deaths at ages <13 years from 1987 through 1999. We examined changes in the numbers and rates of deaths and the proportions reported with various diseases. RESULTS The annual number of children who died with HIV infection increased from 274 in 1987 to 511 in 1994 and then decreased by 81% to 97 in 1999. The median age at death increased from 1 year in 1987 to 5 years in 1999. During the periods 1987 through 1991 (1652 deaths), 1992 through 1995 (1906 deaths) and 1996 through 1999 (762 deaths), the proportion of deaths with pneumocystosis decreased from 19.0% to 9.9% and 7.5%, respectively. In a comparison of 1992 through 1995 with 1996 through 1999, no significant change occurred in the proportions of deaths with nontuberculous mycobacteriosis (5.6% to 6.0%), cytomegalovirus disease (3.2% to 4.4%), heart disease (10.8% to 11.7%), kidney disease (5.0%), liver disease (3.9% to 4.1%) or wasting/cachexia (4.0% to 5.0%). CONCLUSIONS Deaths with HIV infection among children have decreased substantially, probably because of both highly active antiretroviral therapy and prevention of perinatal HIV transmission. The decrease after 1995 was greater proportionally among children than among adults, but fewer changes in disease proportions occurred among children.

Abstract
OBJECTIVE To determine the extent and degree of abnormalities of serum lipids, glucose homeostasis and abdominal adipose tissue distribution in protease inhibitor (PI)-treated and PI-naive HIV-infected children. DESIGN A cross-sectional study involving HIV-infected children, 3-18 years of age, in a paediatric tertiary care centre. MAIN OUTCOME MEASURES Total, HDL and LDL-cholesterol, triglycerides, glucose, insulin, proinsulin and C-peptide were determined in the fasting state. Insulin resistance was assessed using the homeostatic model assessment-insulin resistance (HOMA-IR). Abdominal adipose tissue distribution was determined by single-slice computed tomography at the umbilical level. RESULTS Thirty PI-treated and 20 PI-naive children were evaluated (76% prepubertal). PI-treated children had significantly higher total cholesterol (P = 0.0021), LDL-cholesterol (P = 0.019) and triglycerides (P = 0.0018). Serum glucose, insulin, proinsulin and C-peptide, the insulin : glucose ratio, HOMA-IR and abdominal adipose tissue distribution were similar in the two groups. Clinical and immunological HIV categories, viral load, CD4 cell count and stavudine therapy were not significantly associated with serum lipids, insulin resistance or abdominal adipose tissue distribution. The predictor variable most strongly associated with fasting serum insulin and HOMA-IR was the Tanner stage. Age was the most significant predictor variable of the visceral : subcutaneous adipose tissue ratio. CONCLUSION In this cohort of predominantly prepubertal HIV-infected children, PI therapy was associated with an atherogenic dyslipidemia but not with insulin resistance or abnormal abdominal adipose tissue distribution. The results suggest that children, particularly prepubertal children, are less susceptible than adults to PI-induced changes in glucose homeostasis and abdominal adipose tissue distribution.

Abstract
BACKGROUND Meta-analysis and randomized clinical trial results reported in June 1998 indicated a significant reduction in perinatal HIV transmission rates among mothers undergoing a cesarean section (C-section). OBJECTIVE The objective of this study was to examine recent trends in and factors associated with C-section deliveries among HIV-infected women in the United States. DESIGN A multisite pediatric medical record review of a cohort of HIV-exposed and HIV-infected infants in the Pediatric Spectrum of HIV Disease (PSD) Cohort study (n = 6467) and the national Pediatric HIV/AIDS Reporting System (HARS) (n = 8,306) was conducted. SETTING/PATIENTS All infants born between 1994 and 2000 to HIV-positive mothers referred to the PSD study or to a Pediatric HARS hospital or clinic site were enrolled. RESULTS The proportion of deliveries by C-section was steady at about 20% from 1994 through June 1998. From July 1998 through December 2000, this proportion increased to 44% in the PSD study and to nearly 50% in the Pediatric HARS. On analysis by multiple logistic regression, delivery of infants by C-section was associated with the release of study results (OR = 2.83), delivery in four PSD sites in reference to Texas (OR: 2.02-1.43), having private medical care reimbursement (OR = 1.62), and having maternal prenatal care (OR = 1.43). CONCLUSIONS The PSD and Pediatric HARS data demonstrate a sharp increase in C-section rates mainly among HIV-infected women in the United States after the release of the meta-analysis and randomized clinical trial results in 1998. This finding highlights the rapid impact of study results on obstetric practice. It underscores the critical role of prenatal care in offering perinatal interventions such as scheduled C-section when indicated to reduce the likelihood of HIV transmission.

Abstract
This evaluation examines the changing practices and outcomes of pediatric HIV care provided by the Ryan White Comprehensive AIDS Resources and Emergency (CARE) Act, Title IV grantees from 1996 through 1998--a period of rapidly changing medical practice within the United States. Using medical chart abstraction, 26 Title IV grantees reported information from the records of 525 HIV positive clients between the ages of 2 and 12. The chart abstractions covered medical care and case management provided to these clients including the number of clinical visits, use of antiretroviral therapy, use of laboratory tests such as CD4+ cell count (cells/mm3) and HIV-1 RNA viral load (copies/mL), enrollment in clinical trials, and receipt of opportunistic infection prophylaxis. Information on disease progression and hospitalization as well as client socio-demographic characteristics also is analyzed. Study results indicate that use of HIV combination therapy increased, while the occurrence of opportunistic infections and hospitalizations decreased. The increasing use of new pharmaceuticals during the study period indicates the feasibility of transferring information learned about HIV treatments from clinical trials to clinical practices that treat primarily Medicaid and pediatric populations.

Abstract
OBJECTIVE To compare, by ethnicity, the prevalence of HIV and zidovudine treatment among a cross-sectional survey of childbearing women in California in 1998, and the number of pediatric AIDS cases from 1998 to 2001. METHODS Blood specimens, collected via infant heel-stick for metabolic screening during the third quarter of 1998, were anonymously tested for HIV antibody. Positive specimens were subsequently tested for evidence of zidovudine therapy. Pediatric AIDS cases with diagnosis dates from 1998 to 2001 were obtained from the AIDS case registry. RESULTS Of the 119 108 specimens tested, 77 (0.65 per 1000) were HIV-antibody positive. Most (37.7%) of the 77 HIV-positive specimens were from newborns of African-American mothers, followed closely by Latina mothers (35.1%). The absence of zidovudine therapy was highest for Latina and African-American women, 29.6 and 24.1%, respectively. Latino and African-American children accounted for the majority of California pediatric AIDS cases diagnosed between 1998 and 2001. CONCLUSION Innovative approaches are needed to increase the rate of zidovudine therapy among African-American and Latina HIV-infected childbearing women. These could include a shorter-course zidovudine regimen or rapid HIV testing and counselling of women in late-term pregnancy.

Abstract
Many conditions can cause or be associated with arthritis in childhood. The authors of this paper will review the situations in which underlying immunodeficiency or defective regulation of lymphocyte homeostasis must be suspected, and discuss, for some of these diseases, the genetic bases and pathogenesis. In the second part of this article, the authors will focus on other diseases that can cause arthritis in childhood, often with other symptoms, and for which evidence of an association with genetic abnormalities has been recently discovered. Finally, the authors will discuss the implications of recent findings regarding the role of some genes as causing or modulating factors in juvenile idiopathic arthritis and related disorders, as well as observations made in adults and in animal models of inflammation and autoimmunity.

Abstract
Since the initial descriptions of AIDS in the late 1970s, much has been learned about the biology of HIV-1 and the cells it infects. Much has also been learned about mother-to-infant viral transmission and the natural history of HIV-1 infection. Key studies led to strategies for interrupting mother-to-infant transmission, resulting in a significant decline in neonatal HIV-1 infection. More proficient diagnostic techniques made early diagnosis of HIV-1-infected neonates and infants possible during asymptomatic or mildly symptomatic disease stages. Major advances in treatment led to the control of viral replication and thereby altered the course of disease progression. HIV-1/AIDS-associated neurologic disorders declined in parallel. In countries where these therapies are readily available, a dramatic decline in the number of infants born HIV-1 infected has been realized as has a markedly improved survival rate of those infected. Many questions remain, however. The long-term effects of prenatal exposure to antiretroviral agents are not yet known and continue to be studied. Just exactly how HAART therapy may affect early signs of pediatric HIV-1/AIDS-associated CNS disease, should they develop, is unclear. As new anti-retroviral agents are developed and new combination drug regimens are instituted, the potential for neurologic complications, toxicities, and adverse drug interactions (e.g., with antiepileptic drugs (AEDS)) exists and needs to be identified and monitored.

Abstract
This paper reports on the findings from a multi-site psychosocial study of Canadian families with HIV-positive mothers. A total of 110 adults, representing 91 families across Canada participated in interviews. Qualitative analysis revealed a number of themes including: a complex web of personal, health and family concerns; the needs of children; family finances; disclosure dilemmas; and social experiences and challenges. These themes reflect an intricate and dynamic picture of parental and family life for adults and children living with HIV infection. Nowhere in the literature do we see HIV framed as a 'family infection'. Surveillance reporting reflects information on infected adults and children but not family groupings. Yet with HIV several family members and multiple generations as well as single or both parents may be infected, highlighting the importance of 'family HIV' as a framework for health policy and programme development. At issue is the problem that medical and other institutions view issues of surveillance, treatment and care through the lens of the infected individual, rather than being family focused. Often it is only in the context of identifying support, or barriers to support, for the medically diagnosed individual that biological or socially created families become a focus of concern. The failure to situate both chronic and life-threatening illnesses within the family setting has serious quality of life and planning consequences for parents and children living with HIV infection as well as other illnesses.

Abstract
BACKGROUND A complex interplay of malnutrition, intestinal dysfunction, and immune impairment increases the progression of human immunodeficiency virus (HIV) disease in children. The authors tested the hypothesis that nutritional support improves intestinal and immune functions in children infected with human immunodeficiency virus (HIV). METHODS A questionnaire was circulated through reference centers for pediatric HIV infection to evaluate the effects of nutritional rehabilitation, total parenteral nutrition (TPN) and enteral nutrition (EN), in children. Information included changes in body weight, CD4 cell numbers, and intestinal absorption-as judged by the xylose load-before and after clinical nutritional support and the outcome of children. RESULTS Sixty-two children underwent nutritional support: 46 received TPN and 16 received EN. All but three had full-blown acquired immunodeficiency syndrome, and all were severely malnourished. Baseline clinical conditions were worse in children receiving TPN than in those receiving EN. Intestinal dysfunction was detected in all children who received xylose oral load. A significant increase in CD4 cell count, xylose levels, and body weight followed EN. A similar pattern was observed after TPN, but none of the parameters significantly changed. Twenty-seven children who received TPN and three who received EN eventually died. Fourteen who received TPN and eight who received EN were shifted to oral feeding, and five who received TPN and five who received EN continued with clinical nutritional support at the end of the observation period. CONCLUSIONS Nutritional intervention may restore intestinal absorption and increase CD4 cell numbers. The efficacy of nutritional intervention is enhanced if provided before a terminal stage of HIV infection. These data provide evidence of a close association among nutritional condition, intestinal absorption, and immune impairment.

Abstract
OBJECTIVES This study estimated the prevalence of violence during pregnancy in relation to HIV infection. METHODS Violence, current partnerships, and HIV risk behaviors were assessed among 336 HIV-seropositive and 298 HIV-seronegative at-risk pregnant women. RESULTS Overall, 8.9% of women experienced recent violence; 21.5% currently had abusive partners. Violence was experienced by women in all partnership categories (range = 3.8% with nonabusive partners to 53.6% with physically abusive partners). Neither experiencing violence nor having an abusive partner differed by serostatus. Receiving an HIV diagnosis prenatally did not increase risk. Disclosure-related violence occurred, but was rare. CONCLUSIONS Many HIV-infected pregnant women experience violence, but it is not typically attributable to their serostatus. Prenatal services should incorporate screening and counseling for all women at risk for violence.

Abstract
Children and adolescents are at risk for human immunodeficiency virus (HIV) infection. Transmission occurs through perinatal exposures, injecting drug use, consensual and nonconsensual sex, needle-stick and sharp injuries, and possibly some unusual contacts. Youth engaging in high-risk sexual activities are especially endangered. Half of the estimated worldwide 5.3 million new HIV infections occur in adolescents and young adults aged 15 to 24. Of 20 000 known new adult and adolescent cases in the United States, 25% involve 13- to 21-year-olds. More than 1.4 million children worldwide (aged 15 and younger) are believed to be infected, and >1640 new cases are diagnosed daily. Of the 432 000 people reported to be living with HIV or acquired immunodeficiency syndrome (AIDS) in the United States, 5575 are children under 13. HIV postexposure prophylaxis (PEP) is a form of secondary HIV prevention that may reduce the incidence of HIV infections. HIV PEP is commonly conceived of as 2 types: occupational and nonoccupational. Occupational HIV PEP is an accepted form of therapy for health care workers exposed to HIV through their jobs. A landmark study of healthcare workers concluded that occupational HIV PEP may be efficacious. Well-established US national guidelines for occupational HIV PEP exist for this at-risk population. Nonoccupational HIV PEP includes all other forms of HIV PEP, such as that given after sexual assault and consensual sex, injecting drug use, and needle-stick and sharp injuries in non-health care persons. Pediatric HIV PEP is typically the nonoccupational type. The efficacy of nonoccupational HIV PEP is unknown. The presumed efficacy is based on a collection of animal and human data concerning occupational, perinatal, and nonoccupational exposures to HIV. In contrast to occupational HIV PEP, there are no national US guidelines for nonoccupational HIV PEP, and few recommendations are available for its use for adolescents and children. Regardless of this absence, there is encouraging evidence supporting the value of HIV PEP in its various forms in pediatrics. Although unproven, the presumed mechanism for HIV PEP comes from animal and human work suggesting that shortly after an exposure to HIV, a window period exists during which the viral load is small enough to be controlled by the body's immune system. Antiretroviral medications given during this period may help to diminish or end viral replication, thereby reducing the viral inoculum to a more potentially manageable target for the host's defenses. HIV PEP is accepted practice in the perinatal setting and for health care workers with occupational injuries. The medical literature supports prescribing HIV PEP after community needle-stick and sharp injuries and after sexual assault from sources known or likely to be HIV-infected. HIV PEP after consensual unprotected intercourse between HIV sero-opposite partners has had growing use in the adult population, and can probably be utilized for children and adolescents. There is less documented experience and support for HIV PEP after consensual unprotected intercourse between partners of unknown HIV status, after prolonged or multiple episodes of sexual abuse from an assailant of unknown HIV status, after bites, and after the sharing of personal hygiene items or exposure to wounds of HIV-infected individuals. There are no formal guidelines for HIV PEP in adolescents and children. A few groups have commented on its provision in pediatrics, and some preliminary studies have been released. Our article provides a discussion of the data available on HIV transmission and HIV PEP in pediatrics. In our article, we propose an HIV PEP approach for adolescents and children. We recommend a stratified regimen, based on the work of Gerberding and Katz and other authors, that attempts to match seroconversion risk with an appropriate number of medications, while taking into account adverse side-effects and the amount of information that is typically available upon initial presentation. Twice daily regimens should be used when possible, and may improve compliance. HIV PEP should be administered within 1 hour of exposure. We strongly recommend that physicians trained in this form of therapy review the indications for HIV PEP within 72 hours of its provision. We advocate that due diligence in determining level of risk and appropriateness of drug selection be conducted as soon as possible after an exposure has occurred. When such information is not immediately available, we recommend the rapid treatment using the maximum level of care followed by careful investigation and reconsideration in follow-up or whenever possible. HIV PEP may be initiated provisionally after an exposure and then discontinued if the exposure source is confirmed to not be HIV-infected. In most cases, consultations with the experts in HIV care can occur after the rapid start of therapy. (ABSTRACT TRUNCATED)

Abstract
The past decade has witnessed the emergence of several significant viral pathogens and the further evolution of additional viral pathogens. Transmitted by a variety of differing routes, these organisms have presented substantial intellectual challenges to medicine of the 20th and 21st centuries. As perhaps the benchmark pathogen of the past decade, HIV has provided medicine and society with a most formidable opponent, and one that has yet to be fully conquered. Nonetheless, a variety of additional viral pathogens have also perplexed medicine over the past 10-15 years.

Abstract
In the USA, progress in the ability to eliminate vertical HIV-1 transmission that was unthinkable just a few years ago has been virtually achieved with fewer than 200 new cases of infant HIV infection reported in 1999. Nevertheless, critical research questions as well as public health challenges remain. New infant HIV infections continue to occur among women who did not obtain prenatal care or who were not offered HIV testing during pregnancy and innovative approaches are needed to address these barriers. The CDC-funded Mother-Infant Rapid Intervention At Delivery (MIRIAD) Study in five US metropolitan areas is one such approach that will test the feasibility of offering rapid testing to women presenting late in pregnancy or at delivery with undocumented HIV status. In addition, further research addressing the role of the placenta in preventing or enhancing in utero HIV transmission is needed. Internationally, new clinical trial findings provide hope that a short course of antiretrovirals can substantially reduce vertical HIV-1 transmission in resource-poor settings in the developing world where most paediatric HIV infections occur. Future research will focus on the role of post-perinatal exposure prophylaxis with antiretrovirals administered to the infant and on the prevention of postnatal transmission of HIV-1 through breast milk while maintaining adequate nutrition. A major challenge is to translate trial results into a coordinated public health implementation plan in order to maximally reduce mother-to-child HIV-1 transmission worldwide.

Abstract
1. The human immunodeficiency virus invades the central nervous system early after infection where it later gives rise to cognitive, motor, and behavioral manifestations in children and adults. 2. Ranging from mild impairments to frank dementia, CNS manifestations can be diagnosed and measured with standard neuropsychological test batteries. 3. Great strides have been made with treatment: CNS manifestations are treatable, as are depression, psychosis, and delirium which sometimes accompany HIV disease at different stages. 4. With startling advances in antiretroviral therapy and lower mortality, patients face a constellation of new concerns stemming from HIV's transformation to a more chronic disease. 5. There are many compelling research directions ahead, including the psychosocial impact of living with HIV as a chronic disease, the development of medications expressly targeted to the CNS, and basic research on neuropathogenesis, including trafficking of virus into the CNS.

Abstract
In 1994, the US Public Health Service published guidelines for the use of zidovudine to decrease the risk of perinatal transmission of human immunodeficiency virus (HIV). In 1995, the American Academy of Pediatrics and the US Public Health Service recommended documented, routine HIV education and testing with consent for all pregnant women in the United States. Widespread incorporation of these guidelines into clinical practice has resulted in a dramatic decrease in the rate of perinatal HIV transmission and has contributed to more than a 75% decrease in reported cases of pediatric acquired immunodeficiency syndrome (AIDS) since 1992. Substantial advances have been made in the treatment and monitoring of HIV infection; combination antiretroviral regimens that maximally suppress virus replication are now available. These regimens are recommended for pregnant and nonpregnant individuals who require treatment. Risk factors associated with perinatal HIV transmission are now better understood, and recent results from trials to decrease the rate of mother-to-child HIV transmission have contributed new strategies with established efficacy. However, perinatal HIV transmission still occurs; the Centers for Disease Control and Prevention estimates that 300 to 400 infected infants are born annually. Full implementation of recommendations for universal, routine prenatal HIV testing and evaluation of missed prevention opportunities will be critical to further decrease the incidence of pediatric HIV infection in the United States. This technical report summarizes recent advances in the prevention of perinatal transmission of HIV relevant to screening of pregnant women and their infants.

Abstract
Now in its third decade, the epidemiology of human immunodeficiency virus (HIV) transmission in the United States has changed considerably since the epidemic began. Our increased understanding of the virus has fueled development of new treatments to prolong life, and research into a viable vaccine offers hope to those at risk in developed and less developed countries alike. In this review, we provide information about the current trends in HIV and Acquired Immune Deficiency Syndrome (AIDS) among those in the United States who are hardest hit by the epidemic. We also offer insights into and explanations of these changes; update the epidemiology of HIV subtypes and antiretroviral resistance; and describe current strategies for HIV surveillance.

Abstract
The threshold of a new century is an opportune time to review advances in the prevention of HIV infection in children. In the United States, progress in the ability to virtually eliminate perinatal HIV transmission that was unthinkable just a few years ago has been achieved. Clinicians providing care to pregnant women should educate and counsel women about HIV and strongly recommend that they be tested. They should also counsel HIV-infected women about the means available to substantially decrease the risk for HIV transmission to their infants (e.g., antiretroviral drug use, avoidance of breast-feeding, elective C-section, encouraging pregnant women to use barrier methods during sexual intercourse, and to discontinue injection drug use). This article has highlighted some of the remaining challenges that constitute barriers to achieving maximal decrease of HIV infection in children. Studies conducted in resource-poor countries have added greatly to the understanding of vertical transmission of HIV, and they are now leading to practical and affordable approaches to reduce vertical HIV transmission world-wide. The results of this research must lead to coordinated public health action and a global political commitment to extend the benefits of antiretroviral drug prophylaxis that now exist widely in the United States to more resource-poor countries.
