Maternal nutritional status predicts adverse birth outcomes among HIV-infected rural Ugandan women receiving combination antiretroviral therapy.

ABSTRACT: Maternal nutritional status is an important predictor of birth outcomes, yet little is known about the nutritional status of HIV-infected pregnant women treated with combination antiretroviral therapy (cART). We therefore examined the relationship between maternal BMI at study enrollment, gestational weight gain (GWG), and hemoglobin concentration (Hb) among 166 women initiating cART in rural Uganda.Prospective cohort.HIV-infected, ART-naïve pregnant women were enrolled between 12 and 28 weeks gestation and treated with a protease inhibitor or non-nucleoside reverse transcriptase inhibitor-based combination regimen. Nutritional status was assessed monthly. Neonatal anthropometry was examined at birth. Outcomes were evaluated using multivariate analysis.Mean GWG was 0.17 kg/week, 14.6% of women experienced weight loss during pregnancy, and 44.9% were anemic. Adverse fetal outcomes included low birth weight (LBW) (19.6%), preterm delivery (17.7%), fetal death (3.9%), stunting (21.1%), small-for-gestational age (15.1%), and head-sparing growth restriction (26%). No infants were HIV-infected. Gaining <0.1 kg/week was associated with LBW, preterm delivery, and a composite adverse obstetric/fetal outcome. Maternal weight at 7 months gestation predicted LBW. For each g/dL higher mean Hb, the odds of small-for-gestational age decreased by 52%.In our cohort of HIV-infected women initiating cART during pregnancy, grossly inadequate GWG was common. Infants whose mothers gained <0.1 kg/week were at increased risk for LBW, preterm delivery, and composite adverse birth outcomes. cART by itself may not be sufficient for decreasing the burden of adverse birth outcomes among HIV-infected women.Clinicaltrials.gov NCT00993031.

Project description:BACKGROUND: Long term use of antiretroviral therapy (ART) in persons living with human immunodeficiency virus (PLWHIV) is associated with disturbances in blood lipids which should be monitored. More data on such disturbances are needed in Cameroon to persuade the country program to institute their routine monitoring. We then sought to determine the prevalence and timing of dyslipidaemia in PLWHIV and receiving ART in a predominantly rural Cameroonian setting. METHODS: A cross-sectional study conducted between August and October 2012 in HIV-infected persons aged 15 years or more and receiving first-line ART for at least six months at The Nkongsamba Regional Hospital in Cameroon. Lipid assays were carried out by enzymatic-linked colorimetric methods. A multiple logistic regression model was used to assess for factors related to dyslipidaemia. RESULTS: Included were 114 participants of whom 83 (72.8%) were females. Their median age was 43 years (IQR: 36-51) and their median CD4 count was 436 cells/?l (IQR: 275-585) after a median duration on ART of 36 months (IQR: 12-60). The prevalence of dyslipidaemia was 70.2%. Hypercholesterolaemia was observed in 34 (29.8%) patients. One-third of them had a high LDL-cholesterol level (LDL-c?130 mg/dl). Hypertriglyceridaemia (TG?150 mg/dl) was present in 59 (51.8%) cases. The proportion of patients with a low HDL-cholesterol (HDL-c<40 mg/dl) was 18.4% while those with a ratio of TC/HDL-c?5 were about 16.7%. A duration of 2-4 years on ART (adjusted Odd Ratio, aOR=5.22, 95% CI: 1.43-19.06, p=0.01), current smokers (aOR=15.94, 95% CI: 1.13-225.61, p=0.04) and a concurrent metabolic disease (aOR=12.54, 95% CI: 1.02-153.86, p=0.48) were independently associated with pro-atherogenic LDL-c values. Alcohol users had a more friendly LDL-c profile (aOR=0.24, 95% CI: 0.07-0.74, p=0.01). CONCLUSION: The study has demonstrated a high prevalence of dyslipidaemia in HIV-patients receiving first-line ART in a predominantly rural setting of Cameroon. There is a need for the country HIV program to institute laboratory monitoring of blood lipids in patients over two years on first line ART with a focus on smokers.

Project description:Human immunodeficiency virus (HIV) protease inhibitors show activity against Plasmodium falciparum in vitro. We hypothesized that the incidence of malaria in HIV-infected children would be lower among children receiving lopinavir-ritonavir-based antiretroviral therapy (ART) than among those receiving nonnucleoside reverse-transcriptase inhibitor (NNRTI)-based ART.We conducted an open-label trial in which HIV-infected children 2 months to 5 years of age who were eligible for ART or were currently receiving NNRTI-based ART were randomly assigned to either lopinavir-ritonavir-based ART or NNRTI-based ART and were followed for 6 months to 2 years. Cases of uncomplicated malaria were treated with artemether-lumefantrine. The primary end point was the incidence of malaria.We enrolled 176 children, of whom 170 received the study regimen: 86 received NNRTI-based ART, and 84 lopinavir-ritonavir-based ART. The incidence of malaria was lower among children receiving the lopinavir-ritonavir-based regimen than among those receiving the NNRTI-based regimen (1.32 vs. 2.25 episodes per person-year; incidence-rate ratio, 0.59; 95% confidence interval [CI], 0.36 to 0.97; P=0.04), as was the risk of a recurrence of malaria after treatment with artemether-lumefantrine (28.1% vs. 54.2%; hazard ratio, 0.41; 95% CI, 0.22 to 0.76; P=0.004). The median lumefantrine level on day 7 after treatment for malaria was significantly higher in the lopinavir-ritonavir group than in the NNRTI group. In the lopinavir-ritonavir group, lumefantrine levels exceeding 300 ng per milliliter on day 7 were associated with a reduction of more than 85% in the 63-day risk of recurrent malaria. A greater number of serious adverse events occurred in the lopinavir-ritonavir group than in the NNRTI group (5.6% vs. 2.3%, P=0.16). Pruritus occurred significantly more frequently in the lopinavir-ritonavir group, and elevated alanine aminotransferase levels significantly more frequently in the NNRTI group.Lopinavir-ritonavir-based ART as compared with NNRTI-based ART reduced the incidence of malaria by 41%, with the lower incidence attributable largely to a significant reduction in the recurrence of malaria after treatment with artemether-lumefantrine. Lopinavir-ritonavir-based ART was accompanied by an increase in serious adverse events.

Project description:BackgroundWomen living with HIV (WLHIV) are at higher risk of micronutrient deficiencies and adverse health outcomes. There are limited data on the burden or sequelae of micronutrient deficiencies among pregnant WLHIV receiving antiretroviral therapy (ART).ObjectivesWe aimed to examine anemia and vitamin B-12, folate, and vitamin D deficiencies, and their associations with obstetric and infant outcomes, among pregnant WLHIV initiating combination antiretroviral therapy (cART) in rural Uganda.MethodsThis was a prospective analysis among pregnant WLHIV (12-28 weeks of gestation) in PROMOTE-Pregnant Women and Infants (PIs), a randomized trial comparing the effects of protease inhibitor (PI)-based ART with those of a non-PI-based ART on placental malaria risk. We conducted a substudy on the burden of anemia [trimester 1/3: hemoglobin (Hb) <11.0 g/dL; trimester 2: Hb <10.5 g/dL; n = 367] and micronutrient deficiencies (n = 127) in pregnant WLHIV and their associations with obstetric and infant outcomes. Hb was measured by cyanmethemoglobin, vitamin B-12 and folate were measured via electrochemiluminescence, and vitamin D was measured by ELISA. Linear and binomial regression were used to evaluate associations between micronutrient status during pregnancy and perinatal outcomes.Results26.8% women were anemic, 30.2% were vitamin B-12 insufficient (<221.0 pmol/L), 66.1% were folate insufficient (<13.5 nmol/L), and 65.4% were vitamin D insufficient (<30.0 ng/mL) at enrollment. Anemia during pregnancy was associated with a greater risk of small for gestational age (SGA) (RR: 1.88; 95% CI: 1.28, 2.77; P = 0.001); each 1-g/dL decrease in Hb was associated with greater risk of SGA (RR: 0.76; 95% CI: 0.65, 0.90; P = 0.001). Multivariate models showed that increased vitamin D concentrations predicted lower risk of infant wasting (WLZ < -2; RR: 0.94; 95% CI: 0.89, 0.99; P = 0.04). Multivariate models also indicated that maternal vitamin B-12 and folate concentrations at enrollment predicted maternal (P < 0.001) and infant (P = 0.02) concentrations postpartum.ConclusionsAnemia and micronutrient deficiencies are associated with a variety of adverse obstetric and infant outcomes and are an important public health concern in perinatal WLHIV on cART and their children.This trial was registered at clinicaltrials.gov as NCT00993031.

Project description:BACKGROUND: Significant adverse events (AE) have been reported in patients receiving medications for multidrug- and extensively-drug-resistant tuberculosis (MDR-TB & XDR-TB). However, there is little prospective data on AE in MDR- or XDR-TB/HIV co-infected patients on antituberculosis and antiretroviral therapy (ART) in programmatic settings. METHODS: Médecins Sans Frontières (MSF) is supporting a community-based treatment program for drug-resistant tuberculosis in HIV-infected patients in a slum setting in Mumbai, India since 2007. Patients are being treated for both diseases and the management of AE is done on an outpatient basis whenever possible. Prospective data were analysed to determine the occurrence and nature of AE. RESULTS: Between May 2007 and September 2011, 67 HIV/MDR-TB co-infected patients were being treated with anti-TB treatment and ART; 43.3% were female, median age was 35.5 years (Interquartile Range: 30.5-42) and the median duration of anti-TB treatment was 10 months (range 0.5-30). Overall, AE were common in this cohort: 71%, 63% and 40% of patients experienced one or more mild, moderate or severe AE, respectively. However, they were rarely life-threatening or debilitating. AE occurring most frequently included gastrointestinal symptoms (45% of patients), peripheral neuropathy (38%), hypothyroidism (32%), psychiatric symptoms (29%) and hypokalaemia (23%). Eleven patients were hospitalized for AE and one or more suspect drugs had to be permanently discontinued in 27 (40%). No AE led to indefinite suspension of an entire MDR-TB or ART regimen. CONCLUSIONS: AE occurred frequently in this Mumbai HIV/MDR-TB cohort but not more frequently than in non-HIV patients on similar anti-TB treatment. Most AE can be successfully managed on an outpatient basis through a community-based treatment program, even in a resource-limited setting. Concerns about severe AE in the management of co-infected patients are justified, however, they should not cause delays in the urgently needed rapid scale-up of antiretroviral therapy and second-line anti-TB treatment.

Project description:Adherence to HIV antiretroviral therapy (ART) among children in developing settings is poorly understood.To understand the level, distribution, and correlates of ART adherence behavior, we prospectively determined monthly ART adherence through multiple measures and six-monthly HIV RNA levels among 121 Ugandan children aged 2-10 years for one year. Median adherence levels were 100% by three-day recall, 97.4% by 30-day visual analog scale, 97.3% by unannounced pill count/liquid formulation weights, and 96.3% by medication event monitors (MEMS). Interruptions in MEMS adherence of ? 48 hours were seen in 57.0% of children; 36.3% had detectable HIV RNA at one year. Only MEMS correlated significantly with HIV RNA levels (r = -0.25, p = 0.04). Multivariable regression found the following to be associated with <90% MEMS adherence: hospitalization of child (adjusted odds ratio [AOR] 3.0, 95% confidence interval [CI] 1.6-5.5; p = 0.001), liquid formulation use (AOR 1.4, 95%CI 1.0-2.0; p = 0.04), and caregiver's alcohol use (AOR 3.1, 95%CI 1.8-5.2; p<0.0001). Child's use of co-trimoxazole (AOR 0.5, 95%CI 0.4-0.9; p = 0.009), caregiver's use of ART (AOR 0.6, 95%CI 0.4-0.9; p = 0.03), possible caregiver depression (AOR 0.6, 95%CI 0.4-0.8; p = 0.001), and caregiver feeling ashamed of child's HIV status (AOR 0.5, 95%CI 0.3-0.6; p<0.0001) were protective against <90% MEMS adherence. Change in drug manufacturer (AOR 4.1, 95%CI 1.5-11.5; p = 0.009) and caregiver's alcohol use (AOR 5.5, 95%CI 2.8-10.7; p<0.0001) were associated with ? 48-hour interruptions by MEMS, while second-line ART (AOR 0.3, 95%CI 0.1-0.99; p = 0.049) and increasing assets (AOR 0.7, 95%CI 0.6-0.9; p = 0.0007) were protective against these interruptions.Adherence success depends on a well-established medication taking routine, including caregiver support and adequate education on medication changes. Caregiver-reported depression and shame may reflect fear of poor outcomes, functioning as motivation for the child to adhere. Further research is needed to better understand and build on these key influential factors for adherence intervention development.

Project description:IntroductionThe global antiretroviral therapy era has led to a decline in the number of children newly acquiring HIV and an increase in the number of children who are HIV-exposed and uninfected (HEU). This shift has prompted extensive research focussing on health and survival outcomes of children who are HEU. Study findings, particularly in relation to adverse birth outcomes, have been disparate, inconclusive and have not always been generalisable. Thus, the objectives of this scoping review are (1) to identify and extract definitions used for the adverse birth outcome terms 'low birth weight', 'small for gestational age', 'stillbirth' and 'preterm birth'; (2) to compare the characteristics of studies from which birth outcome definitions were extracted by (a) temporal periods and (b) study country setting (high-income vs low-income and middle-income countries); (3) to use content analysis to map and describe the temporal and geographic distribution of the definitions used and construct a logical model of their evolution.Methods and analysisThe online databases of PubMed/MEDLINE, Scopus, Web of Science, Cochrane Library and CINHAL/EBSCOhost will be used to identify published and grey literature from 2011 to 2022 to identify definitions for the adverse birth outcome terms 'low birth weight', 'small for gestational age', 'stillbirth' and 'preterm birth'. A three-step process of (1) duplicate removal, (2) title and abstract screening and (3) full text screening will be used to select included studies. The extracted data will be used to conduct a comparative analysis, content analysis and construct a logic model.Ethics and disseminationThis review will be used to inform a consensus process around the development of harmonised definitions for the specified adverse birth outcomes. Our dissemination plan includes presentations, publications as well as the development infographics and a resource hub. The study is approved by the Human Research Ethics Committee of Stellenbosch University.
