High prevalence of lipid abnormalities among antiretroviral-naive HIV-infected Asian children with mild-to-moderate immunosuppression.

ABSTRACT: Dyslipidaemia 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 profiles among Asian HIV-infected children naive to ART.A total of 274 HIV-infected ART-naive Thai and Cambodian children aged 1-12 years with CD4% between 15% and 24% were included. Patients were fasted for ?4 h before blood was drawn. Abnormal lipid levels were 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.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) log(10) copies/ml. The median (±SD) fasting time was 13.0 (2.7) h. Mean (±SD) for lipids were 116 (62) mg/dl for TG, 139 (29) mg/dl for TC, 73 (29) mg/dl for LDL and 45 (19) mg/dl for HDL. Overall 63.9% had dyslipidaemia with hypertriglyceridaemia and hypo-HDL being the most common (28% and 45%, respectively), while 2% had hypercholesterolaemia or hyper-LDL. After adjusting for age, having HIV RNA>5 log(10) copies/ml was associated with hypo-HDL with ORs of 8.1 (95% CI 2.7-24.3).Up to two-thirds of ART-naive, HIV-infected Asian children with mild-to-moderate immune suppression had dyslipidaemia. Low HDL was the most common and was associated with high HIV viraemia. The long-term consequence of low HDL deserves further investigation in children.

Project description:Both under- and over-nutrition may occur among human immunodeficiency virus (HIV)-infected individuals and impact on the course of the acquired immune deficiency syndrome (AIDS) and its management due to the close interaction between immunity and nutrition. We investigated occurrence of undernutrition, excess weight and lipid abnormalities among antiretroviral naïve HIV-infected adults in Addis Ababa, Ethiopia.A cross-sectional study on 594 antiretroviral therapy (ART) naïve HIV-infected adults was conducted in four hospitals in Addis Ababa from February to September 2013. Hematological parameters (CD4+ T cell count and hemoglobin concentration), fasting serum glucose, total cholesterol (TC) and triglycerides (TG) were determined. Information on socio-demographic, anthropometric and World Health Organization (WHO) clinical stages was collected from patient clinical records, and triangulated by structured questionnaire. Height and weight measurements were taken and body mass index (BMI), undernutrition (BMI <18.5 kg/m2) and excess weight (BMI ?25 kg/m2) determined. Statistical comparisons were made to identify significant factors associated with nutritional status and lipid profiles.The prevalence of undernutrition was 15.1%, and the prevalence of excess weight was 22.1%, including 5.4% who were obese. The prevalence of hypercholesterolemia was 16.6% and it was higher in women (18.9%) than in men (11.0%) (p<0.05). However, the prevalence of hypertriglyceridemia was 29.8%. There was significant positive Spearman correlation between CD4+ T cell count and serum TC (r = 0.210, p<0.001), but no correlation was observed between CD4+ T cell count and TG (r = -0.007, p>0.05). Age categories 30-39 and 40-79, and WHO clinical stages III/IV for undernutrition; age categories 30-39 and 40-79, WHO clinical stages III/IV and TC ?200 mg/dL for excess weight; and being female, age categories 30-39 and 40-79, and hypertriglyceridemia for hypercholesterolemia were found to be independent predictors by binomial logistic regression analysis.Undernutrition, excess weight, hypercholesterolemia and hypertriglyceridemia were variably prevalent in ART naïve HIV-infected populations. This emphasizes the need for targeted nutritional programs as an integral part of HIV/AIDS care. Lipid levels need to be monitored regularly in patients whether on or off ART. In addition, improvement on household income and positive change in lifestyle and/or nutritional treatment to reduce morbidity and mortality are necessary interventions in HIV/AIDs patient management.

Project description:BackgroundData on the prevalence of renal and urine abnormalities among HIV-infected children in Sub-Saharan Africa are limited. We set out to determine the prevalence of proteinuria; low estimated glomerular filtration rate (eGFR), urinary tract infection and associated factors among HIV-infected antiretroviral therapy (ART) naive children, aged 2-12 years, attending the paediatric HIV clinic at a tertiary hospital in Harare.MethodsConsecutive ART naive children attending the clinic between June and October 2009 were recruited. Detailed medical history was obtained and a complete physical examination was performed. Children were screened for urinary tract infection and for significant persistent proteinuria. Serum creatinine was used to estimate GFR using the modified Counahan-Barratt formula. The Student's t-test was used to analyse continuous variables and the chi-square or Fisher's exact test was used to analyse categorical data. Logistic regression was performed to assess the relationship between study factors and urine abnormalities, persistent proteinuria and the eGFR.ResultsTwo hundred and twenty children were enrolled into the study. The median age was 90 months (Q1=65.5; Q3=116.5). The prevalence of urinary tract infection was 9.5%. Escherichia coli was the predominant organism. There was uniform resistance to cotrimoxazole. Persistent proteinuria (urine protein to creatinine ratio greater than 0.2, a week apart) was found in 5% of the children. Seventy-five children (34.6%) had mild to moderate renal impairment shown by a low eGFR (30 to <90 ml/min/1.73 m2). Persistent proteinuria was more likely to be found in children who were wasted, weight-for-height (WHZ) z-score <-2 (p=0.0005). Children with WHO clinical stage 4 were more likely to have a low eGFR than children with less advanced stages (OR 2.68; CI 1.24-5.80). Urine abnormalities were more likely to be observed in children with WHO clinical stages 3 and 4 (OR 2.20; CI 1.06-4.60).ConclusionThere is significant renal impairment among HIV-infected, ART naive children aged 2-12 years attending the outpatient paediatric HIV clinic at Harare Central Hospital. The abnormalities are more likely to occur in children with advanced HIV/AIDS. Screening for renal impairment and urinary tract infections in HIV-infected children before initiation of ART and regularly thereafter would be helpful in their management.KeywordsHIV, renal disease, persistent proteinuria, glomerular filtration rate, urinary tract infection.

Project description:BackgroundAntiretroviral therapy (ART) has decreased mortality so that increasing numbers of children with HIV are reaching adolescence. However, longstanding HIV infection and/or its treatment in children is associated with noninfectious complications including cardiac disease. We investigated the prevalence, spectrum and risk factors for echocardiographic abnormalities among children established on ART.MethodsHIV-infected children aged 6-16 years, on ART at least 6 months were enrolled into a cross-sectional study from a public-sector paediatric HIV clinic in Harare, Zimbabwe. A standardized examination including transthoracic echocardiography was performed. Local echocardiographic reference ranges were used to define cardiac abnormalities. Logistic regression was used to examine the association between cardiac abnormalities and risk factors.ResultsOf the 201participants recruited, 92 (46%) were girls and median age was 11 (IQR 9-12) years; CD4+ cell count was 727?cells/?l (IQR 473-935) and 154 (78%) had viral load less than 400?copies/ml. Echocardiographic abnormalities were found in 83 (42%); left ventricular (LV) diastolic dysfunction was the most common abnormality 45 (23%) and LV hypertrophy in 22 (11%). LV and left atrial dilatation were found in 9 (5%) and 16 (8%), respectively. Right ventricular dilatation and systolic dysfunction were found in 13 (7%) and 4 (2%), respectively, of whom 60% had concurrent left heart abnormalities. Current use of nevirapine was associated with LVH [aOR 3.14 (1.13-8.72; P?=?0.03)] and hypertension was associated with LV diastolic dysfunction [aOR 3.12 (1.48-6.57; P?<?0.01)].ConclusionHIV-infected children established on ART have a high burden of echocardiographic abnormalities. Right heart disease was predominantly associated with left heart abnormalities and may be part of a global cardiomyopathic process. Further studies are needed to investigate the natural history, aetiology, and pathogenesis of these abnormalities, so that appropriate monitoring and treatment strategies can be developed.
