Uptake of HIV testing and outcomes within a Community-based Therapeutic Care (CTC) programme to treat severe acute malnutrition in Malawi: a descriptive study

Anthropometry at discharge and risk of relapse in children treated for severe acute malnutrition: a prospective cohort study in rural Nepal

Background

There is a dearth of evidence on what should be the optimal criteria for discharging children from severe acute malnutrition (SAM) treatment. Programs discharging children while they are still presenting varying levels of weight-for-height (WHZ) or mid-upper-arm circumference (MUAC) deficits, such as those implemented under the current national protocol in Nepal, are opportunities to fill this evidence gap.

Methods

We followed a cohort of children discharged as cured from SAM treatment in Parasi district, Nepal. Relapse as SAM, defined as the occurrence of WHZ<-3 or MUAC < 115 mm or nutritional edema, was investigated through repeated home visits, during six months after discharge. We assessed the contribution of remaining anthropometric deficits at discharge to relapse risk through Cox regressions.

Results

Relapse as SAM during follow-up was observed in 33 % of the cohort (35/108). Being discharged before reaching the internationally recommended criteria was overall associated with a large increase in the risk of relapse (HR = 3.3; p = 0.006). Among all anthropometric indicators at discharge, WHZ<-2 led to a three-fold increase in relapse risk (HR = 3.2; p = 0.003), while MUAC < 125 mm significantly raised it only in the older children. WHZ<-2 at discharge came up as the only significant predictor of relapse in multivariate analysis (HR = 2.8, p = 0.01), even among children with a MUAC ≥ 125 mm. Of note, more than 80 % of the events of relapse as SAM would have been missed if WHZ had not been monitored and used in the definition of relapse.

Conclusions

Our results suggest that the priority for SAM management programs should be to ensure that children reach a high level of WHZ at discharge, at least above or equal to the WHO recommended cut-off. The validity of using a single MUAC cut-off such as 125 mm as a suitable discharge criterion for all age groups is questioned. Further follow-up studies providing a complete assessment of nutritional status at discharge and not based on a restricted MUAC-only definition of relapse as SAM would be urgently needed to set evidence-based discharge criteria. These studies are also required to assess programs currently discounting or omitting WHZ for identification and management of SAM.

Relapse and regression to severe wasting in children under 5 years: A theoretical framework

Systematic reviews have highlighted that repeated severe wasting after receiving treatment is likely to be common, but standardised measurement is needed urgently. The Council of Research & Technical Advice for Acute Malnutrition (CORTASAM) released recommendations on standard measurement of relapse (wasting within 6 months after exiting treatment as per recommended discharge criteria), regression (wasting within 6 months after exiting treatment before reaching recommended discharge criteria) and reoccurrence (wasting after 6 months of exit from treatment as per recommended discharge criteria). We provide a theoretical framework of post-treatment relapse and regression to severe wasting to guide discussions, risk factor analyses, and development and evaluations of interventions. This framework highlights that there are factors that may impact risk of relapse and regression in addition to the impact of contextual factors associated with incidence and reoccurrence of severe wasting more generally. Factors hypothesised to be associated with relapse and regression relate specifically to the nutrition and health status of the child on admission to, during and exit from treatment and treatment interventions, platforms and approaches as well as type of exit from treatment (e.g., before reaching recommended criteria). These factors influence whether children reach full recovery, and poorer nutritional and immunological status at exit from treatment are more proximate determinants of risk of severe wasting after treatment, although post-treatment interventions may modify risks. The evidence base for many of these factors is weak. Our framework can guide research to improve our understanding of risks of relapse and regression and how to prevent them and inform programmes on what data to collect to evaluate relapse. Implementation research is needed to operationalise results in programmes and reduce post-treatment severe wasting at scale.

HIV risk screening and HIV testing among orphans and vulnerable children in community settings in Tanzania: Acceptability and fidelity to lay-cadre administration of the screening tool

INTRODUCTION

HIV risk screening tool validation studies have not typically included process evaluations to understand tool implementation. The study aim was to assess the fidelity to which an HIV risk screening tool was administered by lay workers and acceptability of delivering home-based screening coupled with HIV testing to beneficiaries in an orphans and vulnerable children (OVC) program.

METHODS

This cross-sectional study was conducted March-April 2019 in two regions of Tanzania. Community case workers (CCW) were observed conducting screenings with OVC 2-19 years and participated in focus group discussions. Research staff used structured observation checklists to capture if screening questions were asked or reworded by CCW. In-depth interviews were conducted with older adolescents and caregivers in their homes following screening and testing. A composite score was developed for the checklist. Qualitative data were thematically analyzed to address screening and testing perceptions and experiences.

RESULTS

CCW (n = 32) participated in 166 observations. Commonly skipped items were malnutrition (34% of all observed screenings) and sexual activity and pregnancy (20% and 45% of screenings for adolescents only). Items frequently re-worded included child abuse (22%) and malnutrition (15%). CCW had an average composite observation score of 42/50. CCW in focus groups (n = 34) found the screening process acceptable. However, they described rewording some questions viewed as harsh or socially inappropriate to ask. Overall, adolescent beneficiaries (n = 17) and caregivers (n = 25) were satisfied with home-based screening and testing and reported no negative consequences. Learning one's HIV negative status was seen as an opportunity to discuss or recommit to healthy behaviors. While respondents identified multiple benefits of home testing, they noted the potential for privacy breaches in household settings.

CONCLUSIONS

We found sub-optimal fidelity to the administration of the screening tool by CCW in home environments to children and adolescents enrolled in an OVC program. Improvements to questions and their delivery and ongoing mentorship could strengthen tool performance and HIV case finding using a targeted testing approach. Overall, home-based HIV risk screening and testing were acceptable to beneficiaries and CCW, could improve testing uptake, and serve as a platform to promote healthy behaviors for those with limited health system interactions.

Development and Validation of a Sociodemographic and Behavioral Characteristics-Based Risk-Score Algorithm for Targeting HIV Testing Among Adults in Kenya

To inform targeted HIV testing, we developed and externally validated a risk-score algorithm that incorporated behavioral characteristics. Outpatient data from five health facilities in western Kenya, comprising 19,458 adults ≥ 15 years tested for HIV from September 2017 to May 2018, were included in univariable and multivariable analyses used for algorithm development. Data for 11,330 adults attending one high-volume facility were used for validation. Using the final algorithm, patients were grouped into four risk-score categories: ≤ 9, 10-15, 16-29 and ≥ 30, with increasing HIV prevalence of 0.6% [95% confidence interval (CI) 0.46-0.75], 1.35% (95% CI 0.85-1.84), 2.65% (95% CI 1.8-3.51), and 15.15% (95% CI 9.03-21.27), respectively. The algorithm's discrimination performance was modest, with an area under the receiver-operating-curve of 0.69 (95% CI 0.53-0.84). In settings where universal testing is not feasible, a risk-score algorithm can identify sub-populations with higher HIV-risk to be prioritized for HIV testing.

They are likely to be there: using a family-centered index testing approach to identify children living with HIV in Kenya

In Kenya, only half of children with a parent living with HIV have been tested for HIV. The effectiveness of family-centered index testing to identify children (0-14 years) living with HIV was examined. A retrospective record review was conducted among adult index patients newly enrolled in HIV care between May and July 2015; family testing, results, and linkage to treatment outcomes were followed through May 2016 at 60 high-volume clinics in Kenya. Chi square test compared yield (percentage of HIV tests positive) among children tested through family-centered index testing, outpatient and inpatient testing. Review of 1937 index client charts led to 3005 eligible children identified for testing. Of 2848 (94.8%) children tested through family-centered index testing, 127 (4.5%) had HIV diagnosed, 100 (78.7%) were linked to care, and 85 of those eligible (91.4%) initiated antiretroviral therapy (ART).Family testing resulted in higher yield compared to inpatient (1.8%, p < 0.001) or outpatient testing (1.6%, p < 0.001). The absolute number of children living with HIV identified was highest with outpatient testing. The relative contribution of testing approach to total children identified with HIV was outpatient testing (69%), family testing (26%), and inpatient testing (5%). The family testing approach demonstrated promise in achieving the first two "90s" (identification and ART initiation) of the 90-90-90 targets for children, with additional effort required to improve linkage from testing to treatment.

Measuring growth and medium- and longer-term outcomes in malnourished children

Severe and moderate acute malnutrition are among the leading causes of mortality among children in low- and middle-income countries. There is strong evidence that growth assessed anthropometrically from conception to 2 years of age marks later risk of ill health. This is central to the concept of the developmental origins of adult disease and is presumed to be related to modification of developmental processes during critical "window(s)" of vulnerability. Interventions to treat acute malnutrition have resulted in dramatic increase in the number of affected children surviving. Ensuring that these children thrive to fulfil their full physical and cognitive potential is a new challenge. Integral to this challenge is the need to be able to measure how earlier insults relate to the ability to survive and thrive to productive adulthood. Despite its obvious value, routine anthropometry does not adequately indicate how earlier adverse exposures affect more refined aspects of growth. Anthropometry is inadequate for predicting how disruption of healthy growth might modulate risk of disease or any subsequent interventions that correct this risk. A clear characterisation of healthy child growth is needed for determining which component best predicts later outcomes. The extent to which postnatal acute malnutrition is a consequence of maternal factors acting preconception or in utero and their relationship to postnatal health and long-term risk of non-communicable diseases is not clear. Body-composition measurement has significant untapped potential allowing us to translate and better understand the relationship between early insults and interventions on early growth in the short-term and long-term health outcomes.

Addition of Questions on Parental Factors to the WHO (Integrated Management of Childhood Illnesses) IMCI-HIV Algorithm Improves the Utility of the Algorithm for Diagnosis of HIV Infection in Children

The WHO Integrated Management of Childhood Illnesses-HIV (IMCI-HIV) algorithm and its regional adaptation have shown variable performance in clinically identifying HIV-infected children with lack of validation in low prevalence areas. Addition of certain 'parental factors' (proxy indicators of parental HIV) may improve its utility. In this study, children aged 2 months to 5 years were enrolled into Group A (n = 1000, 'suspected symptomatic HIV infected' children as per the IMNCI-HIV algorithm) and group B (n = 50, children newly diagnosed with HIV infection). Parental factors were asked and HIV infection was tested for in Group A. For Group B, retrospective data were collected regarding IMNCI-HIV algorithm signs and parental factors. Utility of individual and various combinations of IMNCI-HIV signs and parental factors to predict HIV status was evaluated. Results showed that incorporating parental factors to IMNCI-HIV algorithm improved its sensitivity and positive predictive value in identifying HIV-infected children while maintaining the same sensitivity.

Relapse after severe acute malnutrition: A systematic literature review and secondary data analysis

The objectives of most treatment programs for severe acute malnutrition (SAM) in children focus on initial recovery only, leaving post‐discharge outcomes, such as relapse, poorly understood and undefined. This study aimed to systematically review current literature and conduct secondary data analyses of studies that captured relapse rates, up to 18‐month post‐discharge, in children following recovery from SAM treatment. The literature search (including PubMed and Google Scholar) built upon two recent reviews to identify a variety of up‐to‐date published studies and grey literature. This search yielded 26 articles and programme reports that provided information on relapse. The proportion of children who relapsed after SAM treatment varied greatly from 0% to 37% across varying lengths of time following discharge. The lack of a standard definition of relapse limited comparability even among the few studies that have quantified post‐discharge relapse. Inconsistent treatment protocols and poor adherence to protocols likely add to the wide range of relapse reported. Secondary analysis of a database from Malawi found no significant association between potential individual risk factors at admission and discharge, except being an orphan, which resulted in five times greater odds of relapse at 6 months post‐discharge (95% CI [1.7, 12.4], P = 0.003). The development of a standard definition of relapse is needed for programme implementers and researchers. This will allow for assessment of programme quality regarding sustained recovery and better understanding of the contribution of relapse to local and global burden of SAM.

Follow-up between 6 and 24 months after discharge from treatment for severe acute malnutrition in children aged 6-59 months: A systematic review

BACKGROUND

Severe acute malnutrition (SAM) is a major global health problem affecting some 16.9 million children under five. Little is known about what happens to children 6-24 months post-discharge as this window often falls through the gap between studies on SFPs and those focusing on longer-term effects.

METHODS

A protocol was registered on PROSPERO (PROSPERO 2017:CRD42017065650). Embase, Global Health and MEDLINE In-Process and Non-Indexed Citations were systematically searched with terms related to SAM, nutritional intervention and follow-up between June and August 2017. Studies were selected if they included children who experienced an episode of SAM, received a therapeutic feeding intervention, were discharged as cured and presented any outcome from follow-up between 6-24 months later.

RESULTS

3,691 articles were retrieved from the search, 55 full-texts were screened and seven met the inclusion criteria. Loss-to-follow-up, mortality, relapse, morbidity and anthropometry were outcomes reported. Between 0.0% and 45.1% of cohorts were lost-to-follow-up. Of those discharged as nutritionally cured, mortality ranged from 0.06% to 10.4% at an average of 12 months post-discharge. Relapse was inconsistently defined, measured, and reported, ranging from 0% to 6.3%. Two studies reported improved weight-for-height z-scores, whilst three studies that reported height-for-age z-scores found either limited or no improvement.

CONCLUSIONS

Overall, there is a scarcity of studies that follow-up children 6-24 months post-discharge from SAM treatment. Limited data that exists suggest that children may exhibit sustained vulnerability even after achieving nutritional cure, including heightened mortality and morbidity risk and persistent stunting. Prospective cohort studies assessing a wider range of outcomes in children post-SAM treatment are a priority, as are intervention studies exploring how to improve post-SAM outcomes and identify high-risk children.

Assessment of provider-initiated HIV screening in Nigeria with sub-Saharan African comparison

Background

Despite Nigeria’s high HIV prevalence, voluntary testing and counselling rates remain low. UNAIDS/WHO/CDC recommends provider-initiated testing and counselling (PITC) for HIV in settings with high HIV prevalence. We aimed to assess the acceptability and logistical feasibility of the PITC strategy among adolescents and adults in a secondary health care centre in Idekpa Benue state, Nigeria.

Method

All patients (aged ≥ 13 years) who visited the out-patient department and antenatal care unit of General Hospital Idekpa, Benue state, Nigeria were offered PITC for HIV. The intervention was implemented by trained health professionals for the period spanning (June to December 2010).

Results

Among the 212 patients who were offered PITC for HIV, 199 (94%) accepted HIV testing, 10 patients (4.7%) opted out and 3 patients (1.4%) were undecided. Of the 199 participants who were tested for HIV, 9% were HIV seropositive. The PITC strategy was highly acceptable and feasible, and increased the number of patients who tested for HIV by 5% compared to voluntary counselling and testing. Findings from this assessment were consistent with those from other sub-Saharan African countries (such as Uganda and South Africa).

Conclusion

PITC for HIV was highly acceptable and logistically feasible, and resulted in an increased rate of HIV testing among patients. Public health initiatives (such as the PITC strategy) that facilitate early detection of HIV and referral for early treatment should be encouraged for broader HIV control and prevention in Nigerian communities.

Predictors of Infant Age at Enrollment in Early Infant Diagnosis Services in Kenya

Despite the importance of early detection to signal lifesaving treatment initiation for HIV+ infants, early infant diagnosis (EID) services have received considerably less attention than other aspects of prevention of mother to child transmission care. This study draws on baseline data from an on-going cluster randomized study of an intervention to improve EID services at six government hospitals across Kenya. Two logistic regressions examined potential predictors of “on time” (infant ≤6 weeks of age) vs. “late” (≥7 weeks) and “on time” versus “very late” (≥12 weeks) EID engagement among 756 mother-infant pairs. A quarter of the infants failed to get “on time” testing. Predictors of “on time” testing included being informed about EID by providers when pregnant, perceiving less HIV stigma, and mother’s level of education. Predictors of “very late” testing (≥12 weeks of age) included not being informed about EID by providers when pregnant and living farther from services. Findings highlight the importance of ensuring that health care providers actively and repeatedly inform HIV+ mothers of the availability of EID services, reduce stigma by frequently communicating judgment free support, and assisting mothers in early planning for accessing EID services. Extra care should be focused on engaging mothers with less formal education who are at increased risk for seeking “late” EID testing. This study offers clear targets for improving services so that all HIV-exposed infants can be properly engaged in EID services, thus increasing the potential for the best possible outcomes for this vulnerable population.

Paediatric HIV testing beyond the context of prevention of mother-to-child transmission: a systematic review and meta-analysis

BACKGROUND

Many HIV-positive children in low-income and middle-income countries remain undiagnosed. Although HIV testing in children at health facilities is recommended by WHO, it is not well implemented. This systematic review and meta-analysis examines the case-finding benefit of HIV screening in children aged 0-5 years in low-income and middle-income countries.

METHODS

We did this systematic review and meta-analysis in accordance with an a-priori protocol. We searched PubMed, MEDLINE, WHO Global Index Medicus, Web of Science, Médecins Sans Frontières, Cochrane, Embase, CABS Abstracts, and LILACS databases for articles published between Jan 1, 2004, and April 30, 2016, that reported the quantitative prevalence of HIV detected through screening in four key contexts (paediatric inpatient settings, paediatric outpatient settings, nutrition centres, and expanded programme on immunisation centres) in paediatric populations in low-income and middle-income countries. Articles were identified and data were extracted in duplicate. The primary outcome was HIV prevalence, for which we used a DerSimonian-Laird random-effects meta-analysis to pool prevalence data and 95% CIs. We did stratified analyses according to geographical context and testing strategy. This study is registered with PROSPERO, number CRD42014014372.

FINDINGS

Our search found 2996 studies, of which 26 met the inclusion criteria. Paediatric HIV prevalence across all settings was 15·6% (95% CI 11·8-19·5). HIV prevalence by setting was highest in paediatric inpatient settings (21·1%, 95% CI 14·9-27·3), followed by nutrition centres (13·1%, 95% CI 3·4-22·7), expanded programme on immunisation centres (3·3%, 95% CI 0-6·9), and paediatric outpatient settings (2·7%, 95% CI 0·3-5·2). Universal testing and testing triggered by symptoms had similar diagnostic yield in the inpatient setting (21·3%, 95% CI 11·6-31·0 in triggered testing vs 20·9%, 95% CI 13·5-28·3 in universal testing).

INTERPRETATION

HIV testing in paediatric populations in low-income and middle-income countries outside the context of prevention of mother-to-child transmission programmes provides an important opportunity to identify HIV-positive children. For countries wishing to prioritise interventions, the highest diagnostic yields were obtained from inpatient wards and nutrition centres. Universal testing might be the preferred approach since it did not have a substantially lower diagnostic yield than triggered testing

FUNDING

None.

Cereals and pulse-based ready-to-use therapeutic food as an alternative to the standard milk- and peanut paste-based formulation for treating severe acute malnutrition: a noninferiority, individually randomized controlled efficacy clinical trial

BACKGROUND

The cost of current standard ready-to-use therapeutic food (RUTF) is among the major obstacles to scaling up community-based management of acute malnutrition (CMAM), an important child survival strategy. Identifying a cheaper alternative is a global public health priority.

OBJECTIVE

We sought to compare the efficacy of soya-maize-sorghum RUTF (SMS-RUTF) with that of standard peanut paste-based RUTF (P-RUTF).

DESIGN

We used a nonblinded, parallel-group, simple randomized controlled trial along with a day care approach that enrolled 2 groups of children aged 6-23 and 24-59 mo, respectively, with severe acute malnutrition (SAM).

RESULTS

Intention-to-treat (ITT) and per-protocol (PP) analyses showed noninferiority of SMS-RUTF compared with P-RUTF for the recovery rate [ITT: Δ = -2.0% (95% CI: -7.6%, 3.6%); PP: -1.9% (95% CI: -5.3%, 1.4%)], weight gain [Δ = -0.7 g · kg(-1)· d(-1)(95% CI: -1.3, 0.0 g · kg(-1)· d(-1))], and length of stay [Δ = 2.0 d (95% CI: -1.7, 5.8 d)] in children ≥24 mo of age. In children ≤23 mo of age, the recovery rate of SMS-RUTF was inferior to that of P-RUTF [ITT: Δ = -20.8% (95% CI: -29.9%, -11.7%); PP: -17.2% (95% CI: -25.6%, -8.7%)]. Treatment with SMS-RUTF resulted in a greater increase in hemoglobin [0.670 g/dL (95% CI: 0.420, 0.921 g/dL);P< 0.001]. Treatment with both RUTFs resulted in the replenishment of all of the amino acids tested except for methionine. There were no differences at discharge between RUTF groups in fat mass [Δ = 0.3 kg (95% CI: -0.6, 1.6 kg);P= 0.341] or fat mass index [Δ = 0.4 kg/m(2)(95% CI: -0.3, 1.1 kg/m(2));P= 0.262]. By contrast, comparisons of fat-free mass indicated lower concentrations than the community controls after treatment with either of the 2 RUTFs [Δ = -1.3 kg (95% CI: -2.4, -0.1 kg) andP= 0.034 for comparison between community controls and the SMS-RUTF group; Δ = -1.8 kg (95% CI: -2.9, -0.6 kg) andP= 0.003 for comparison between community controls and the P-RUTF group].

CONCLUSION

SMS-RUTF can be used to treat SAM in children aged ≥24 mo to reduce the costs of CMAM programs. More research is required to optimize SMS-RUTF for younger children. This trial was registered in the Pan African Clinical Trial Registry as PACTR201303000475166.

Validation of a screening tool to identify older children living with HIV in primary care facilities in high HIV prevalence settings

Objective:

We previously proposed a simple tool consisting of five items to screen for risk of HIV infection in adolescents (10–19 years) in Zimbabwe. The objective of this study is to validate the performance of this screening tool in children aged 6–15 years attending primary healthcare facilities in Zimbabwe.

Methods:

Children who had not been previously tested for HIV underwent testing with caregiver consent. The screening tool was modified to include four of the original five items to be appropriate for the younger age range, and was administered. A receiver operator characteristic analysis was conducted to determine a suitable cut-off score. The sensitivity, specificity and predictive value of the modified tool were assessed against the HIV test result.

Results:

A total of 9568 children, median age 9 (interquartile, IQR: 7–11) years and 4971 (52%) men, underwent HIV testing. HIV prevalence was 4.7% (95% confidence interval, CI:4.2–5.1%) and increased from 1.4% among those scoring zero on the tool to 63.6% among those scoring four (P < 0.001). Using a score of not less than one as the cut-off for HIV testing, the tool had a sensitivity of 80.4% (95% CI:76.5–84.0%), specificity of 66.3% (95% CI:65.3–67.2%), positive predictive value of 10.4% and a negative predictive value of 98.6%. The number needed to screen to identify one child living with HIV would drop from 22 to 10 if this screening tool was used.

Conclusion:

The screening tool is a simple and sensitive method to identify children living with HIV in this setting. It can be used by lay healthcare workers and help prioritize limited resources.

Integration of HIV in child survival platforms: a novel programmatic pathway towards the 90-90-90 targets

Introduction

Integration of HIV into child survival platforms is an evolving territory with multiple connotations. Most literature on integration of HIV into other health services focuses on adults; however promising practices for children are emerging. These include the Double Dividend (DD) framework, a new programming approach with dual goal of improving paediatric HIV care and child survival. In this commentary, the authors discuss why integrating HIV testing, treatment and care into child survival platforms is important, as well as its potential to advance progress towards global targets that call for, by 2020, 90% of children living with HIV to know their status, 90% of those diagnosed to be on treatment and 90% of those on treatment to be virally suppressed (90–90–90).

Discussion

Integration is critical in improving health outcomes and efficiency gains. In children, integration of HIV in programmes such as immunization and nutrition has been associated with an increased uptake of HIV infant testing. Integration is increasingly recognized as a case-finding strategy for children missed from prevention of mother-to-child transmission programmes and as a platform for diffusing emerging technologies such as point-of-care diagnostics. These support progress towards the 90–90–90 targets by providing a pathway for early identification of HIV-infected children with co-morbidities, prompt initiation of treatment and improved survival. There are various promising practices that have demonstrated HIV outcomes; however, few have documented the benefits of integration on child survival interventions. The DD framework is well positioned to address the bidirectional impacts for both programmes.

Conclusions

Integration provides an important programmatic pathway for accelerated progress towards the 90–90–90 targets. Despite this encouraging information, there are still challenges to be addressed in order to maximize the benefits of integration.

Comparison of the effectiveness of a milk-free soy-maize-sorghum-based ready-to-use therapeutic food to standard ready-to-use therapeutic food with 25% milk in nutrition management of severely acutely malnourished Zambian children: an equivalence non-blinded cluster randomised controlled trial

Community-based Management of Acute Malnutrition using ready-to-use therapeutic food (RUTF) has revolutionised the treatment of severe acute malnutrition (SAM). However, 25% milk content in standard peanut-based RUTF (P-RUTF) makes it too expensive. The effectiveness of milk-free RUTF has not been reported hitherto. This non-blinded, parallel group, cluster randomised, controlled, equivalence trial that compares the effectiveness of a milk-free soy-maize-sorghum-based RUTF (SMS-RUTF) with P-RUTF in treatment of children with SAM, closes the gap. A statistician randomly assigned health centres (HC) either to the SMS-RUTF (n = 12; 824 enrolled) or P-RUTF (n = 12; 1103 enrolled) arms. All SAM children admitted at the participating HCs were enrolled. All the outcomes were measured at individual level. Recovery rate was the primary outcome. The recovery rates for SMS-RUTF and P-RUTF were 53.3% and 60.8% for the intention-to-treat (ITT) analysis and 77.9% and 81.8% for per protocol (PP) analyses, respectively. The corresponding adjusted risk difference (ARD) and 95% confidence interval, were -7.6% (-14.9, 0.6%) and -3.5% (-9,6., 2.7%) for ITT (P = 0.034) and PP analyses (P = 0.257), respectively. An unanticipated interaction (interaction P < 0.001 for ITT analyses and 0.0683 for PP analyses) between the study arm and age group was observed. The ARDs were -10.0 (-17.7 to -2.3)% for ITT (P = 0.013) and -4.7 (-10.0 to 0.7) for PP (P = 0.083) analyses for the <24 months age group and 2.1 (-10.3,14.6)% for ITT (P = 0.726) and -0.6 (-16.1, 14.5) for PP (P = 0.939) for the ≥24 months age group. In conclusion, the study did not confirm our hypothesis of equivalence between SMS-RUTF and P-RUTF in SAM management.

What Health Service Provider Factors Are Associated with Low Delivery of HIV Testing to Children with Acute Malnutrition in Dowa District of Malawi?

Background

The Community-based Management of Acute Malnutrition is the national program for treating acute malnutrition in Malawi. Under this program’s guidelines all children enrolled should undergo an HIV test, so that those infected can receive appropriate treatment and care. However, the national data of 2012 shows a low delivery of testing. Prior studies have investigated client-related factors affecting uptake of HIV testing in Community-based Management of Acute Malnutrition program. Lacking is the information on the service provider factors that are associated with the delivery of testing. This study investigated service provider factors that affect delivery of HIV testing among children enrolled in the program and explored ways in which this could be improved.

Methods

A descriptive study that used qualitative methods of data collection. Client registers were reviewed to obtain the number of children enrolled in Community-based Management of Acute Malnutrition and the number of children who were tested for HIV over a 12-month period. In-depth interviews were conducted with Community-based Management of Acute Malnutrition and HIV Testing and Counselling focal persons to investigate factors affecting HIV test delivery. Descriptive statistics were used to analyze data from client registers. Information from interviews was analyzed using a thematic approach.

Results

Quantitative data revealed that 1738 (58%) of 2981 children enrolled in Community-based Management of Acute Malnutrition were tested for HIV. From in-depth interviews four themes emerged, that is, lack of resources for HIV tests; shortage of staff skilled in HIV testing and counseling; lack of commitment among staff in referring children for HIV testing; and inadequately trained staff.

Conclusion

There is a need for a functioning health system to help reduce child mortality resulting from HIV related conditions.

Severe acute malnutrition and infection

Severe acute malnutrition (SAM) is associated with increased severity of common infectious diseases, and death amongst children with SAM is almost always as a result of infection. The diagnosis and management of infection are often different in malnourished versus well-nourished children. The objectives of this brief are to outline the evidence underpinning important practical questions relating to the management of infectious diseases in children with SAM and to highlight research gaps. Overall, the evidence base for many aspects covered in this brief is very poor. The brief addresses antimicrobials; antipyretics; tuberculosis; HIV; malaria; pneumonia; diarrhoea; sepsis; measles; urinary tract infection; nosocomial Infections; soil transmitted helminths; skin infections and pharmacology in the context of SAM. The brief is structured into sets of clinical questions, which we hope will maximise the relevance to contemporary practice.

Follow-up of post-discharge growth and mortality after treatment for severe acute malnutrition (FuSAM study): a prospective cohort study

BACKGROUND

Management of Severe Acute Malnutrition (SAM) plays a vital role in achieving global child survival targets. Effective treatment programmes are available but little is known about longer term outcomes following programme discharge.

METHODS

From July 2006 to March 2007, 1024 children (median age 21.5 months, IQR 15-32) contributed 1187 admission episodes to an inpatient-based SAM treatment centre in Blantyre, Malawi. Long term outcomes, were determined in a longitudinal cohort study, a year or more after initial programme discharge. We found information on 88%(899/1024).

RESULTS

In total, 42%(427/1024) children died during or after treatment. 25%(105/427) of deaths occurred after normal programme discharge, >90 days after admission. Mortality was greatest among HIV seropositive children: 62%(274/445). Other risk factors included age <12 months; severity of malnutrition at admission; and disability. In survivors, weight-for-height and weight-for-age improved but height-for-age remained low, mean -2.97 z-scores (SD 1.3).

CONCLUSIONS

Although SAM mortality in this setting was unacceptably high, our findings offer important lessons for future programming, policy and research. First is the need for improved programme evaluation: most routine reporting systems would have missed late deaths and underestimated total mortality due to SAM. Second, a more holistic view of SAM is needed: while treatment will always focus on nutritional interventions, it is vital to also identify and manage underlying clinical conditions such as HIV and disability. Finally early identification and treatment of SAM should be emphasised: our results suggest that this could improve longer term as well as short term outcomes. As international policy and programming becomes increasingly focused on stunting and post-malnutrition chronic disease outcomes, SAM should not be forgotten. Proactive prevention and treatment services are essential, not only to reduce mortality in the short term but also because they have potential to impact on longer term morbidity, growth and development of survivors.

Effectiveness of milk whey protein-based ready-to-use therapeutic food in treatment of severe acute malnutrition in Malawian under-5 children: a randomised, double-blind, controlled non-inferiority clinical trial

The cost of ready‐to‐use therapeutic food (RUTF) used in community‐based management of acute malnutrition has been a major obstacle to the scale up of this important child survival strategy. The current standard recipe for RUTF [peanut‐based RUTF (P‐RUTF)] is made from peanut paste, milk powder, oil, sugar, and minerals and vitamins. Milk powder forms about 30% of the ingredients and may represent over half the cost of the final product. The quality of whey protein concentrates 34% (WPC34) is similar to that of dried skimmed milk (DSM) used in the standard recipe and can be 25–33% cheaper. This blinded, parallel group, randomised, controlled non‐inferiority clinical trial tested the effectiveness in treating severe acute malnutrition (SAM) of a new RUTF formulation WPC‐RUTF in which WPC34 was used to replace DSM. Average weight gain (non‐inferiority margin Δ = −1.2 g kg⁻¹ day⁻¹) and recovery rate (Δ = −10%) were the primary outcomes, and length of stay (LOS) was the secondary outcome (Δ = +14 days). Both per‐protocol (PP) and intention‐to‐treat (ITT) analyses showed that WPC‐RUTF was not inferior to P‐RUTF for recovery rate [difference and its 95% confidence interval (CI) of 0.5% (95% CI –2.7, 3.7) in PP analysis and 0.6% (95% CI –5.2, 6.3) in ITT analysis] for average weight gain [0.2 (−0.5; 0.9) for both analyses] and LOS [−1.6 days (95% CI, −4.6, 1.4 days) in PP analysis and −1.9 days (95% CI, −4.6, 0.8 days) for ITT analysis]. In conclusion, whey protein‐based RUTF is an effective cheaper alternative to the standard milk‐based RUTF for the treatment of SAM.

Improving survival of children with severe acute malnutrition in HIV-prevalent settings

The care of severely malnourished children in sub-Saharan Africa is challenging, especially in HIV-prevalent settings. Recent improvements to facility-based individual case management, and increased community-based management focusing on early identification and high programme coverage have led to reductions in mortality. Further interventions are urgently needed to address resistant mortality, mostly attributable to HIV. This paper explores strategies in three main areas to improve survival for children with severe acute malnutrition (SAM): identifying HIV and improving case management for HIV-infected children; strengthening existing strategies to improve outcomes for all children with SAM, regardless of HIV status; and improving early identification and increasing programme coverage. Although interventions to further improve survival among children with SAM in sub-Saharan Africa must firstly ensure best care for all children, HIV-infected children are at particular risks for mortality. Integration of specific interventions for HIV testing and treatment into SAM care is essential. International guidelines should reflect best evidence, and are in urgent need of updating and adapting to local country context. Effective interventions already exist that can improve survival in children with SAM in HIV-prevalent settings. The challenge is to implement what we know and to research what we do not.

Towards universal voluntary HIV testing and counselling: a systematic review and meta-analysis of community-based approaches

BACKGROUND

Effective national and global HIV responses require a significant expansion of HIV testing and counselling (HTC) to expand access to prevention and care. Facility-based HTC, while essential, is unlikely to meet national and global targets on its own. This article systematically reviews the evidence for community-based HTC.

METHODS AND FINDINGS

PubMed was searched on 4 March 2013, clinical trial registries were searched on 3 September 2012, and Embase and the World Health Organization Global Index Medicus were searched on 10 April 2012 for studies including community-based HTC (i.e., HTC outside of health facilities). Randomised controlled trials, and observational studies were eligible if they included a community-based testing approach and reported one or more of the following outcomes: uptake, proportion receiving their first HIV test, CD4 value at diagnosis, linkage to care, HIV positivity rate, HTC coverage, HIV incidence, or cost per person tested (outcomes are defined fully in the text). The following community-based HTC approaches were reviewed: (1) door-to-door testing (systematically offering HTC to homes in a catchment area), (2) mobile testing for the general population (offering HTC via a mobile HTC service), (3) index testing (offering HTC to household members of people with HIV and persons who may have been exposed to HIV), (4) mobile testing for men who have sex with men, (5) mobile testing for people who inject drugs, (6) mobile testing for female sex workers, (7) mobile testing for adolescents, (8) self-testing, (9) workplace HTC, (10) church-based HTC, and (11) school-based HTC. The Newcastle-Ottawa Quality Assessment Scale and the Cochrane Collaboration's "risk of bias" tool were used to assess the risk of bias in studies with a comparator arm included in pooled estimates. 117 studies, including 864,651 participants completing HTC, met the inclusion criteria. The percentage of people offered community-based HTC who accepted HTC was as follows: index testing, 88% of 12,052 participants; self-testing, 87% of 1,839 participants; mobile testing, 87% of 79,475 participants; door-to-door testing, 80% of 555,267 participants; workplace testing, 67% of 62,406 participants; and school-based testing, 62% of 2,593 participants. Mobile HTC uptake among key populations (men who have sex with men, people who inject drugs, female sex workers, and adolescents) ranged from 9% to 100% (among 41,110 participants across studies), with heterogeneity related to how testing was offered. Community-based approaches increased HTC uptake (relative risk [RR] 10.65, 95% confidence interval [CI] 6.27-18.08), the proportion of first-time testers (RR 1.23, 95% CI 1.06-1.42), and the proportion of participants with CD4 counts above 350 cells/µl (RR 1.42, 95% CI 1.16-1.74), and obtained a lower positivity rate (RR 0.59, 95% CI 0.37-0.96), relative to facility-based approaches. 80% (95% CI 75%-85%) of 5,832 community-based HTC participants obtained a CD4 measurement following HIV diagnosis, and 73% (95% CI 61%-85%) of 527 community-based HTC participants initiated antiretroviral therapy following a CD4 measurement indicating eligibility. The data on linking participants without HIV to prevention services were limited. In low- and middle-income countries, the cost per person tested ranged from US$2-US$126. At the population level, community-based HTC increased HTC coverage (RR 7.07, 95% CI 3.52-14.22) and reduced HIV incidence (RR 0.86, 95% CI 0.73-1.02), although the incidence reduction lacked statistical significance. No studies reported any harm arising as a result of having been tested.

CONCLUSIONS

Community-based HTC achieved high rates of HTC uptake, reached people with high CD4 counts, and linked people to care. It also obtained a lower HIV positivity rate relative to facility-based approaches. Further research is needed to further improve acceptability of community-based HTC for key populations. HIV programmes should offer community-based HTC linked to prevention and care, in addition to facility-based HTC, to support increased access to HIV prevention, care, and treatment.

Development of a cross-over randomized trial method to determine the acceptability and safety of novel ready-to-use therapeutic foods

OBJECTIVE

To develop a method for determining the acceptability and safety of ready-to-use therapeutic foods (RUTF) before clinical trialing. Acceptability was defined using a combination of three consumption, nine safety, and six preference criteria. These were used to compare a soy/maize/sorghum RUTF (SMS-RUTFh), designed for the rehabilitation of human immunodeficiency virus/tuberculosis (HIV/TB) wasted adults, with a peanut-butter/milk-powder paste (P-RUTF; brand: Plumpy'nut) designed for pediatric treatment.

METHODS

A cross-over, randomized, controlled trial was conducted in Kenya. Ten days of repeated measures of product intake by 41 HIV/TB patients, >18 y old, body mass index (BMI) 18-24 kg · m(-2), 250 g were offered daily under direct observation as a replacement lunch meal. Consumption, comorbidity, and preferences were recorded.

RESULTS

The study arms had similar age, sex, marital status, initial BMI, and middle upper-arm circumference. No carryover effect or serious adverse events were found. SMS-RUTFh energy intake was not statistically different from the control, when adjusted for BMI on day 1, and the presence of throat sores. General preference, taste, and sweetness scores were higher for SMS-RUTFh compared to the control (P < 0.05). Most consumption, safety, and preference criteria for SMS-RUTFh were satisfied except for the average number of days of nausea (0.16 versus 0.09 d) and vomiting (0.04 versus 0.02 d), which occurred with a higher frequency (P < 0.05).

CONCLUSION

SMS-RUTFh appears to be acceptable and can be safely clinically trialed, if close monitoring of vomiting and nausea is included. The method reported here is a useful and feasible approach for testing the acceptability of ready-to-use foods in low income countries.

Integration of HIV/AIDS services with maternal, neonatal and child health, nutrition, and family planning services

BACKGROUND

The integration of HIV/AIDS and maternal, neonatal, child health and nutrition services (MNCHN), including family planning (FP) is recognized as a key strategy to reduce maternal and child mortality and control the HIV/AIDS epidemic. However, limited evidence exists on the effectiveness of service integration.

OBJECTIVES

To evaluate the impact of integrating MNCHN-FP and HIV/AIDS services on health, behavioral, and economic outcomes and to identify research gaps.

SEARCH METHODS

Using the Cochrane Collaboration's validated search strategies for identifying reports of HIV interventions, along with appropriate keywords and MeSH terms, we searched a range of electronic databases, including the Cochrane Central Register of Controlled Trials (CENTRAL), Cumulative Index to Nursing and Allied Health Literature (CINAHL), EMBASE, MEDLINE (via PubMed), and Web of Science / Web of Social Science. The date range was from 01 January 1990 to 15 October 2010. There were no limits to language.

SELECTION CRITERIA

Included studies were published in peer-reviewed journals, and provided intervention evaluation data (pre-post or multi-arm study design).The interventions described were organizational strategies or change, process modifications or introductions of technologies aimed at integrating MNCHN-FP and HIV/AIDS service delivery.

DATA COLLECTION AND ANALYSIS

We identified 10,619 citations from the electronic database searches and 101 citations from hand searching, cross-reference searching and interpersonal communication. After initial screenings for relevance by pairs of authors working independently, a total of 121 full-text articles were obtained for closer examination.

MAIN RESULTS

Twenty peer-reviewed articles representing 19 interventions met inclusion criteria. There were no randomized controlled trials. One study utilized a stepped wedge design, while the rest were non-randomized trials, cohort studies, time series studies, cross-sectional studies, serial cross-sectional studies, and before-after studies. It was not possible to perform meta-analysis. Risk of bias was generally high. We found high between-study heterogeneity in terms of intervention types, study objectives, settings and designs, and reported outcomes. Most studies integrated FP with HIV testing (n=7) or HIV care and treatment (n=4). Overall, HIV and MNCHN-FP service integration was found to be feasible across a variety of integration models, settings and target populations. Nearly all studies reported positive post-integration effects on key outcomes including contraceptive use, antiretroviral therapy initiation in pregnancy, HIV testing, and quality of services.

AUTHORS' CONCLUSIONS

This systematic review's findings show that integrated HIV/AIDS and MNCHN-FP services are feasible to implement and show promise towards improving a variety of health and behavioral outcomes. However, significant evidence gaps remain. Rigorous research comparing outcomes of integrated with non-integrated services, including cost, cost-effectiveness, and health outcomes such as HIV and STI incidence, morbidity and mortality are greatly needed to inform programs and policy.

Facilitating HIV testing, care and treatment for orphans and vulnerable children aged five years and younger through community-based early childhood development playcentres in rural Zimbabwe

Introduction

Early diagnosis of children living with HIV is a prerequisite for accessing timely paediatric HIV care and treatment services and for optimizing treatment outcomes. Testing of HIV-exposed infants at 6 weeks and later is part of the national prevention of mother to child transmission (PMTCT) of HIV programme in Zimbabwe, but many opportunities to test infants and children are being missed. Early childhood development (ECD) playcentres can act as an entry point providing multiple health and social services for orphans and vulnerable children (OVC) under 5 years, including facilitating access to HIV treatment and care.

Methods

Sixteen rural community-based, community-run ECD playcentres were established to provide health, nutritional and psychosocial support for OVC aged 5 years and younger exposed to or living with HIV, coupled with family support groups (FSGs) for their families/caregivers. These centres were located in close proximity to health centres giving access to nurse-led monitoring of 697 OVC and their caregivers. Community mobilisers identified OVC within the community, supported their registration process and followed up defaulters. Records profiling each child's attendance, development and health status (including illness episodes), vaccinations and HIV status were compiled at the playcentres and regularly reviewed, updated and acted upon by nurse supervisors. Through FSGs, community cadres and a range of officers from local services established linkages and built the capacity of parents/caregivers and communities to provide protection, aid psychosocial development and facilitate referral for treatment and support.

Results

Available data as of September 2011 for 16 rural centres indicate that 58.8% (n=410) of the 697 children attending the centres were tested for HIV; 18% (n=74) tested positive and were initiated on antibiotic prophylaxis. All those deemed eligible for antiretroviral therapy were commenced on treatment and adherence was monitored.

Conclusions

This community-based playcentre model strengthens comprehensive care (improving emotional, cognitive and physical development) for OVC younger than 5 years and provides opportunities for caregivers to access testing, care and treatment for children exposed to, affected by and infected with HIV in a secure and supportive environment. More research is required to evaluate barriers to counselling and testing of young children and the long-term impact of playcentres upon specific health and developmental outcomes.

Prompt initiation of ART With therapeutic food is associated with improved outcomes in HIV-infected Malawian children with malnutrition

This retrospective observational study of 140 HIV-infected children with uncomplicated malnutrition in urban Malawi tested the hypothesis that initiation of antiretroviral therapy (ART) within 21 days of outpatient therapeutic feeding (prompt ART) improved clinical outcomes. Children receiving prompt ART were more likely to recover nutritionally (86% vs. 60%, P < 0.01) and had higher rates of weight gain (3.6 vs. 1.6 g/k/day; P = 0.02). Logistic regression modeling found prompt ART was associated with increased likelihood of nutritional recovery (odds ratio: 5.4, 95% confidence interval: 2.0 to 14.5). This suggests that prompt ART is associated with improved outcomes in HIV-infected Malawian children with uncomplicated malnutrition.

Cost-effectiveness of community-based management of acute malnutrition in Malawi

This study assessed the cost-effectiveness of community-based management of acute malnutrition (CMAM) to prevent deaths due to severe acute malnutrition among children under-five. The analysis used a decision tree model to compare the costs and effects of two options to treat severe acute malnutrition: existing health services with CMAM vs existing health services without CMAM. The model used outcome and cost data from a CMAM programme in Dowa district, Malawi and a set of key assumptions regarding treatment-seeking behaviour and mortality outcomes. Under our 'base case' scenario, we found that CMAM cost US$42 per disability-adjusted life year (DALY) averted (2007 US$) and US$493 per DALY averted under an assumed 'worst case' scenario for each variable. The results suggest that CMAM was highly cost-effective in the 'base case' as defined by the World Health Organization, as the cost per DALY falls well below Malawi's 2007 gross national income (GNI) per capita of US$250, and is within the range of DALYs reported for other child health interventions. Under a hypothetical 'worst case' for all variables, the model indicates CMAM is still cost-effective. The results indicate the decision to scale-up CMAM within essential health services in Dowa was a cost-effective one and that scaling up CMAM in similar contexts is also likely to be cost-effective. However, several contextual and programmatic factors should be considered when generalizing to diverse contexts.

A primary care level algorithm for identifying HIV-infected adolescents in populations at high risk through mother-to-child transmission

Objective

To present an algorithm for primary-care health workers for identifying HIV-infected adolescents in populations at high risk through mother-to-child transmission.

Methods

Five hundred and six adolescent (10–18 years) attendees to two primary care clinics in Harare, Zimbabwe, were recruited. A randomly extracted ‘training’ data set (n = 251) was used to generate an algorithm using variables identified as associated with HIV through multivariable logistic regression. Performance characteristics of the algorithm were evaluated in the remaining (‘test’) records (n = 255) at different HIV prevalence rates.

Results

HIV prevalence was 17%, and infection was independently associated with client-reported orphanhood, past hospitalization, skin problems, presenting with sexually transmitted infection and poor functional ability. Classifying adolescents as requiring HIV testing if they reported >1 of these five criteria had 74% sensitivity and 80% specificity for HIV, with the algorithm correctly predicting the HIV status of 79% of participants. In low-HIV-prevalence settings (<2%), the algorithm would have a high negative predictive value (≥99.5%) and result in an estimated 60% decrease in the number of people needing to test to identify one HIV-infected individual, compared with universal testing.

Conclusions

Our simple algorithm can identify which individuals are likely to be HIV infected with sufficient accuracy to provide a screening tool for use in settings not already implementing universal testing policies among this age-group, for example immigrants to low-HIV-prevalence countries.

Acceptance of HIV testing for children ages 18 months to 13 years identified through voluntary, home-based HIV counseling and testing in western Kenya

BACKGROUND

Home-based voluntary counseling and testing (HCT) presents a novel approach to early diagnosis. We sought to describe uptake of pediatric HIV testing, associated factors, and HIV prevalence among children offered HCT in Kenya.

METHODS

The USAID-Academic Model Providing Access to Healthcare Partnership conducted HCT in western Kenya in 2008. Children 18 months to 13 years were offered HCT if their mother was known to be dead, her living status was unknown, mother was HIV infected, or of unknown HIV status. This retrospective analysis describes the cohort of children encountered and tested.

RESULTS

HCT was offered to 2289 children and accepted for 1294 (57%). Children were more likely to be tested if more information was available about a suspected or confirmed maternal HIV infection [for HIV-infected living mothers odds ratio (OR) = 3.20, 95% confidence interval (CI): 1.64 to 6.23), if parents were not in household (OR = 1.50, 95% CI: 1.40 to 1.63), if they were grandchildren of head of household (OR = 4.02, 95% CI: 3.06 to 5.28), or if their father was not in household (OR = 1.41, 95% CI: 1.24 to 1.56). Of the eligible children tested, 60 (4.6%) were HIV infected.

CONCLUSIONS

HCT provides an opportunity to identify HIV among high-risk children; however, acceptance of HCT for children was limited. Further investigation is needed to identify and overcome barriers to testing uptake.

Lessons learned from family-centred models of treatment for children living with HIV: current approaches and future directions

BACKGROUND

Despite strong global interest in family-centred HIV care models, no reviews exist that detail the current approaches to family-centred care and their impact on the health of children with HIV. A systematic review of family-centred HIV care programmes was conducted in order to describe both programme components and paediatric cohort characteristics.

METHODS

We searched online databases, including PubMed and the International AIDS Society abstract database, using systematic criteria. Data were extracted regarding programme setting, staffing, services available and enrolment methods, as well as cohort demographics and paediatric outcomes.

RESULTS

The search yielded 25 publications and abstracts describing 22 separate cohorts. These contained between 43 and 657 children, and varied widely in terms of staffing, services provided, enrolment methods and cohort demographics. Data on clinical outcomes was limited, but generally positive. Excellent adherence, retention in care, and low mortality and/or loss to follow up were documented.

CONCLUSIONS

The family-centred model of care addresses many needs of infected patients and other household members. Major reported obstacles involved recruiting one or more types of family members into care, early diagnosis and treatment of infected children, preventing mortality during children's first six months of highly active antiretroviral therapy, and staffing and infrastructural limitations. Recommendations include: developing interventions to enrol hard-to-reach populations; identifying high-risk patients at treatment initiation and providing specialized care; and designing and implementing evidence-based care packages. Increased research on family-centred care, and better documentation of interventions and outcomes is also critical.

Features associated with underlying HIV infection in severe acute childhood malnutrition: a cross sectional study

INTRODUCTION

Up to half of all children presenting to Nutrition Rehabilitation Units (NRUs) in Malawi with severe acute malnutrition (SAM) are infected with HIV. There are many similarities in the clinical presentation of SAM and HIV. It is important to identify HIV infected children, in order to improve case management. This study aims to identify features suggestive of HIV in children with SAM.

METHODS

All 1024 children admitted to the Blantyre NRU between July 2006 and March 2007 had demographic, anthropometric and clinical characteristics documented on admission. HIV status was known for 904 children, with 445 (43%) seropositive and 459 (45%) seronegative. Features associated with HIV were determined.

RESULTS

Associations were found for the following signs: chronic ear discharge (OR 14.6, 95%CI 5.8-36.7), lymphadenopathy (6.4, 3.5-11.7), clubbing (4.9, 2.6-9.4), marasmus (4.9, 3.5-6.8), hepato-splenomegally (3.2, 1.8-5.6), and oral candida (2.4, 1.8-3.27). Any one of these signs was present in 74% of the HIV seropositive, and 38% of HIV uninfected children. A history of recurrent respiratory infection (OR 9.6, 4.8-18.6), persistent fever, recent outpatient attendance, or hospital admission were also associated with HIV. Persistent diarrhoea was no more frequent in HIV (OR 1.1). Orphaning (OR 2.1, 1.4-3.3) or a household contact with TB (OR 1.7, 1.1-2.6), were more common in HIV. Each of these features were present in >10% of seropositive children. HIV infected children were more stunted, wasted, and anaemic than uninfected children.

CONCLUSIONS

Features commonly associated with HIV were often present in uninfected children with SAM, and HIV could neither be diagnosed, nor excluded using these. We recommend HIV testing be offered to all children with SAM where HIV is prevalent.
