The need to update the classification of acute malnutrition

Comparison of Mid-Upper-Arm Circumference and Weight-For-Height Z-Score in Identifying Severe Acute Malnutrition among Children Aged 6-59 Months in South Gondar Zone, Ethiopia

Children with severe acute malnutrition (SAM) are identified for admission to outpatient therapeutic programs using mid-upper-arm circumference (MUAC) or weight for height (WHZ). However, MUAC and WHZ do not identify the same children, and such observed differences might have programmatic implications of missed nutrition therapy if only MUAC is used to identify children with SAM. The objective of the study was to assess any difference in prevalence and degree of agreement between MUAC and WHZ in identifying SAM affected children. A cross-sectional study was conducted in South Gondar Zone, Ethiopia, among 17 districts, with 3 districts and 10 health centers with their clustered health posts selected randomly. A total of 2,040 children were recruited, and data were collected using a parent questionnaire then entered into EpiData and analyzed using SPSS v 20. A total of 1,980 respondents (97.1%) were interviewed, all of whom were female and rural residents. Children's mean age in months was 23.2 (SD ± 9.7), and 54% were male children. The prevalence of SAM based on MUAC <11.5 cm was 11.2% (95% CI: 9.9–12.7) and 11.0% (95% CI: 9.7–12.5) based on WHZ <−3. The agreement between MUAC and WHZ was good (k = 0.729). The proportion of children with SAM identified using both MUAC and WHZ was 61.2%. The prevalence of SAM identified using both MUAC and WHZ was comparable. A substantial degree of agreement between MUAC and WHZ was observed to diagnose SAM. Therefore, MUAC can be used as an appropriate tool in identifying children with SAM for admission into the outpatient therapeutic program (OTP) in the study area.

Severe acute malnutrition and its associated factors among children under-five years: a facility-based cross-sectional study

BACKGROUND

Despite consistent efforts to enhance child nutrition, poor nutritional status of children continues to be a major public health problem in Nepal. This study identified the predictors of severe acute malnutrition (SAM) among children aged 6 to 59 months in the two districts of Nepal.

METHODS

We used data from a cross-sectional study conducted among 6 to 59 months children admitted to the Outpatient Therapeutic Care Centers (OTCC). The nutritional status of children was assessed using mid-upper arm circumference (MUAC) measurement. To determine which variables predict the occurrence of SAM, adjusted odds ratio was computed using multivariate logistic regression and p-value < 0.05 was considered as significant.

RESULTS

Out of 398 children, 5.8% were severely malnourished and the higher percentage of female children were malnourished. Multivariate analysis showed that severe acute malnutrition was significantly associated with family size (five or more members) (Adjusted Odds Ratio [AOR]: 3.96; 95% Confidence Interval [CI]: 1.23-12.71). Children from severely food insecure households (AOR: 4.04; 95% CI: 1.88-10.53) were four times more likely to be severely malnourished. Higher odds of SAM were found among younger age-group (AOR: 12.10; 95% CI: 2.06-71.09) children (0-12 vs. 24-59 months).

CONCLUSIONS

The findings of this study indicated that household size, household food access, and the child's age were the major predictors of severe acute malnutrition. Engaging poor families in kitchen gardening to ensure household food access and nutritious diet to the children, along with health education and promotion to the mothers of young children are therefore recommended to reduce child undernutrition.

Predictors of relapse of acute malnutrition following exit from community-based management program in Amhara region, Northwest Ethiopia: An unmatched case-control study

BACKGROUND

Community-based management of acute malnutrition (CMAM) is an effective program to manage children with acute malnutrition, including both severe and moderate acute malnutrition. However, little is known about continued child nutritional status after discharge from community based management of acute malnutrition programs in Ethiopia.

OBJECTIVE

The study aimed to identify factors associated with relapse of acute malnutrition among children 6-59 months after been discharged recovered from community based management program in South Gondar Zone, Northwest Ethiopia.

METHODS

A case-control study was conducted in three districts of South Gondar Zone by tracing children age 6-59 months who were reported as recovered from the community based management program. Sample size calculated for the first objective of assessing prevalence of severe acute malnutrition among children following discharge as recovery using Epi- Info version 7.1.3.3 StatCalc taking 95% CL, 17.8% post discharge relapse (Ashraf H, et al. (2012), 3% margin of error, design effect of 2 and adding 5% non-response rate was the largest sample size and used to this study. Children with Mid Upper Arm Circumference (MUAC) <12.5cm constituted cases and children with > = 12.5cm served as controls. Data were collected from 10 November 2017 to 30 January 2018 using a survey questionnaire and families were asked to bring children to a health facility for anthropometric measurements, following which data were entered and analyzed. Bivariate and multivariable logistic regression models were utilized to measure association between the risk factors and acute malnutrition.

RESULTS

Overall, 1,273 participants were interviewed. The mean age in months of children was 23.1 (±9.1 SD) for cases and 23.1 (±8.9 SD) for controls. About 40% of the cases and 50% of the controls were female children. The factors associated with acute malnutrition were: male children (AOR = 1.84, 95% CI: 1.42-2.39), living in a food insecure household (AOR = 1.67, 95% CI:1.15-2.44), non-receipt of Vitamin A supplement (AOR = 1.76, 95% CI: 1.28-2.41), prelacteal feeding (AOR = 2.81 (95%CI, 1.57-5.05), distance to water source more than 15 walk (AOR = 1.88, 95% CI:1.32-2.71), less frequent self-reported hand washing (AOR = 1.35, 95% CI:1.05-1.75), mother not having consumed extra food during this pregnancy/lactation (AOR = 1.36, 95% CI: 1.03-1.78), and respondent age above 30 years (AOR = 1.43, 95% CI:1.10-1.87).

CONCLUSION

The key factors contributing to relapse of acute malnutrition were related to childcare and feeding practices. Social and behavior change communication strategies targeting families at risk of undernutrition, along with improved food security and integrated programming are recommended to prevent relapse of acute malnutrition.

Rural children remain more at risk of acute malnutrition following exit from community based management of acute malnutrition program in South Gondar Zone, Amhara Region, Ethiopia: a comparative cross-sectional study

BACKGROUND

Community-based management of acute malnutrition has been reported effective in terms of recovery rate, but recovered children may be at increased risk of developing acute malnutrition after returning to the same household (HH) environment.

OBJECTIVE

Compare the magnitude and factors associated with acute malnutrition among recovered and never treated children in South Gondar Zone, Amhara Region, Ethiopia.

METHOD

A comparative cross-sectional study was conducted in three districts of South Gondar Zone by tracing 720 recovered and an equal number of age matched children who were never treated for acute malnutrition. Parents were asked to bring children to health post for survey data collection, anthropometric measurements, and edema assessment. Data were collected using a survey questionnaire, entered in to EpiData and analyzed using SPSS v20. Anthropometric indices were generated according to the WHO's 2006 Child Growth Standards using WHO Anthro software version 3.2.2. Bivariate and multivariable logistic regression was utilized. Values with P < 0.05 were considered statistically significant and Odds Ratio with 95% CI was used to measure strength of association.

RESULT

A total of 1,440 parents were invited, of which 1,414 participated (98.2% response rate). Mean age in months of children (±SD) was 23.7 (±10.4) for recovered and 23.3 (±10.8) for comparison group. About 49% of recovered and 46% of comparison children were females. A significant difference was observed on magnitude of acute malnutrition between recovered (34.2% (95% CI [30.9-38.0]) and comparison groups (26.7% (95% CI [23.5-30.2]), P = 0.002. Factors associated with acute malnutrition among recovered were district of Ebnat (AOR = 3.7; 95% CI [1.9-7.2]), Tach-Gayint (AOR = 2.4; 95% CI [1.2-4.7]); male child (AOR = 1.4; 95% CI [1.0-2.0]); prelactal feeding (AOR = 2.6; 95% CI [1.3 -5.1]); not feeding colostrum (AOR = 1.5; 95% CI [1.1-2.3]); not consuming additional food during pregnancy/lactation (AOR = 1.6; 95% CI [1.1-2.3]); not given Vitamin A supplement (AOR = 2.1; 95% CI [1.4-3.2]); and safe child feces disposal practice (AOR = 1.7; 95% CI [1.2-2.5]) while district of Tach-Gayint (AOR = 2.5; 95% CI [1.3-4.8]); male child (AOR = 1.5; 95% CI [1.1-2.1]), not feeding colostrum (AOR = 1.7; 95% CI [1.2-2.5]), poor hand washing practice (AOR = 1.6; 95% CI [1.1-2.2]); food insecure HH (AOR = 1.6; 95% CI [1.1-2.4]), birth interval <24 months (AOR = 1.9; 95% CI [1.2-3.2]), and poor access to health facility (AOR = 1.7; 95% CI [1.2-2.4]) were factors associated with acute malnutrition among comparison group.

CONCLUSION

Recovered children were more at risk of acute malnutrition than the comparison group. Nutrition programs should invest in improving nutrition counseling and education; as well as the hygienic practices to protect children against post-discharge relapse of acute malnutrition.

Ready-to-use therapeutic food (RUTF) for home-based nutritional rehabilitation of severe acute malnutrition in children from six months to five years of age

BACKGROUND

Management of severe acute malnutrition (SAM) in children comprises two potential phases: stabilisation and rehabilitation. During the initial stabilisation phase, children receive treatment for dehydration, electrolyte imbalances, intercurrent infections and other complications. In the rehabilitation phase (applicable to children presenting with uncomplicated SAM or those with complicated SAM after complications have been resolved), catch-up growth is the main focus and the recommended energy and protein requirements are much higher. In-hospital rehabilitation of children with SAM is not always desirable or practical - especially in rural settings - and home-based care can offer a better solution. Ready-to-use therapeutic food (RUTF) is a widely used option for home-based rehabilitation, but the findings of our previous review were inconclusive.

OBJECTIVES

To assess the effects of home-based RUTF used during the rehabilitation phase of SAM in children aged between six months and five years on recovery, relapse, mortality and rate of weight gain.

SEARCH METHODS

We searched the following databases in October 2018: CENTRAL, MEDLINE, Embase, six other databases and three trials registers. We ran separate searches for cost-effectiveness studies, contacted researchers and healthcare professionals in the field, and checked bibliographies of included studies and relevant reviews.

SELECTION CRITERIA

Randomised controlled trials (RCTs) and quasi-RCTs, where children aged between six months and five years with SAM were, during the rehabilitation phase, treated at home with RUTF compared to an alternative dietary approach, or with different regimens and formulations of RUTF compared to each other. We assessed recovery, deterioration or relapse and mortality as primary outcomes; and rate of weight gain, time to recovery, anthropometrical changes, cognitive development and function, adverse outcomes and acceptability as secondary outcomes.

DATA COLLECTION AND ANALYSIS

We screened for eligible studies, extracted data and assessed risk of bias of those included, independently and in duplicate. Where data allowed, we performed a random-effects meta-analysis using Review Manager 5, and investigated substantial heterogeneity through subgroup and sensitivity analyses. For the main outcomes, we evaluated the quality of the evidence using GRADE, and presented results in a 'Summary of findings' table per comparison.

MAIN RESULTS

We included 15 eligible studies (n = 7976; effective sample size = 6630), four of which were cluster trials. Eight studies were conducted in Malawi, four in India, and one apiece in Kenya, Zambia, and Cambodia. Six studies received funding or donations from industry whereas eight did not, and one study did not report the funding source.The overall risk of bias was high for six studies, unclear for three studies, and low for six studies. Among the 14 studies that contributed to meta-analyses, none (n = 5), some (n = 5) or all (n = 4) children were stabilised in hospital prior to commencement of the study. One small study included only children known to be HIV-infected, another study stratified the analysis for 'recovery' according to HIV status, while the remaining studies included HIV-uninfected or untested children. Across all studies, the intervention lasted between 8 and 16 weeks. Only five studies followed up children postintervention (maximum of six months), and generally reported on a limited number of outcomes.We found seven studies with 2261 children comparing home-based RUTF meeting the World Health Organization (WHO) recommendations for nutritional composition (referred to in this review as standard RUTF) with an alternative dietary approach (effective sample size = 1964). RUTF probably improves recovery (risk ratio (RR) 1.33; 95% confidence interval (CI) 1.16 to 1.54; 6 studies, 1852 children; moderate-quality evidence), and may increase the rate of weight gain slightly (mean difference (MD) 1.12 g/kg/day, 95% CI 0.27 to 1.96; 4 studies, 1450 children; low-quality evidence), but we do not know the effects on relapse (RR 0.55, 95% CI 0.30 to 1.01; 4 studies, 1505 children; very low-quality evidence) and mortality (RR 1.05, 95% CI 0.51 to 2.16; 4 studies, 1505 children; very low-quality evidence).Two quasi-randomised cluster trials compared standard, home-based RUTF meeting total daily nutritional requirements with a similar RUTF but given as a supplement to the usual diet (213 children; effective sample size = 210). Meta-analysis showed that standard RUTF meeting total daily nutritional requirements may improve recovery (RR 1.41, 95% CI 1.19 to 1.68; low-quality evidence) and reduce relapse (RR 0.11, 95% CI 0.01 to 0.85; low-quality evidence), but the effects are unknown for mortality (RR 1.36, 95% CI 0.46 to 4.04; very low-quality evidence) and rate of weight gain (MD 1.21 g/kg/day, 95% CI - 0.74 to 3.16; very low-quality evidence).Eight studies randomised 5502 children (effective sample size = 4456) and compared standard home-based RUTF with RUTFs of alternative formulations (e.g. using locally available ingredients, containing less or no milk powder, containing specific fatty acids, or with added pre- and probiotics). For recovery, it made little or no difference whether standard or alternative formulation RUTF was used (RR 1.03, 95% CI 0.99 to 1.08; 6 studies, 4188 children; high-quality evidence). Standard RUTF decreases relapse (RR 0.84, 95% CI 0.72 to 0.98; 6 studies, 4188 children; high-quality evidence). However, it probably makes little or no difference to mortality (RR 1.00, 95% CI 0.80 to 1.24; 7 studies, 4309 children; moderate-quality evidence) and may make little or no difference to the rate of weight gain (MD 0.11 g/kg/day, 95% CI -0.32 to 0.54; 6 studies, 3807 children; low-quality evidence) whether standard or alternative formulation RUTF is used.

AUTHORS' CONCLUSIONS

Compared to alternative dietary approaches, standard RUTF probably improves recovery and may increase rate of weight gain slightly, but the effects on relapse and mortality are unknown. Standard RUTF meeting total daily nutritional requirements may improve recovery and relapse compared to a similar RUTF given as a supplement to the usual diet, but the effects on mortality and rate of weight gain are not clear. When comparing RUTFs with different formulations, the current evidence does not favour a particular formulation, except for relapse, which is reduced with standard RUTF. Well-designed, adequately powered, pragmatic RCTs with standardised outcome measures, stratified by HIV status, and that include diarrhoea as an outcome, are needed.

Severely malnourished children with a low weight-for-height have a higher mortality than those with a low mid-upper-arm-circumference: I. Empirical data demonstrates Simpson's paradox

BACKGROUND

According to WHO childhood severe acute malnutrition (SAM) is diagnosed when the weight-for-height Z-score (WHZ) is <-3Z of the WHO2006 standards, the mid-upper-arm circumference (MUAC) is < 115 mm, there is nutritional oedema or any combination of these parameters. Recently there has been a move to eliminate WHZ as a diagnostic criterion on the assertion that children meeting the WHZ criterion are healthy, that MUAC is universally a superior prognostic indicator of mortality and that adding WHZ to the assessment does not improve the prediction; these assertions have lead to a controversy concerning the role of WHZ in the diagnosis of SAM.

METHODS

We examined the mortality experience of 76,887 6-60 month old severely malnourished children admitted for treatment to in-patient, out-patient or supplementary feeding facilities in 18 African countries, of whom 3588 died. They were divided into 7 different diagnostic categories for analysis of mortality rates by comparison of case fatality rates, relative risk of death and meta-analysis of the difference between children admitted using MUAC and WHZ criteria.

RESULTS

The mortality rate was higher in those children fulfilling the WHO2006 WHZ criterion than the MUAC criterion. This was the case for younger as well as older children and in all regions except for marasmic children in East Africa. Those fulfilling both criteria had a higher mortality. Nutritional oedema increased the risk of death. Having oedema and a low WHZ dramatically increased the mortality rate whereas addition of the MUAC criterion to either oedema-alone or oedema plus a low WHZ did not further increase the mortality rate. The data were subject to extreme confounding giving Simpson's paradox, which reversed the apparent mortality rates when children fulfilling both WHZ and MUAC criteria were included in the estimation of the risk of death of those fulfilling either the WHZ or MUAC criteria alone.

CONCLUSIONS

Children with a low WHZ, but a MUAC above the SAM cut-off point are at high risk of death. Simpson's paradox due to confounding from oedema and mathematical coupling may make previous statistical analyses which failed to distinguish the diagnostic groups an unreliable guide to policy. WHZ needs to be retained as an independent criterion for diagnosis of SAM and methods found to identify those children with a low WHZ, but not a low MUAC, in the community.

Use of tuberculin skin test for assessment of immune recovery among previously malnourished children in Ethiopia

OBJECTIVE

To compare levels of immunity in children recovering from severe acute malnutrition (cases) against those of community controls (controls).

RESULTS

At baseline children recovering from severe acute malnutrition had lower, mid upper arm circumference (122 mm for cases and 135 mm for controls; p < 0.001), weight-for-height Z-score (- 1.0 for cases and - 0.5 for controls; p < 0.001), weight-for-age Z-score (- 2.8 for cases and - 1.1 for controls; p < 0.001) and height/length-for-age Z-score (- 3.6 for cases and - 1.4 for controls; p < 0.001), than controls. Age and gender matched community controls. At baseline, prevalence of a positive tuberculin skin test, assessed by cutaneous delayed-type hypersensitivity reaction skin test, was very low in both cases (3/93 = 3.2%) and controls (2/94 = 2.1%) and did not significantly increase at 6 months follow up (6/86 = 7.0% in cases and 3/84 = 3.4% in controls). The incidences of common childhood morbidities, namely fever, diarrhoea and cough, were 1.7-1.8 times higher among cases than controls. In conclusion, these results show that tuberculin skin test does not enable any conclusive statements regarding the immune status of patients following treatment for severe acute malnutrition. The increased incidence of infection in cases compared to controls suggests persistence of lower resistance to infection even after anthropometric recovery is achieved.

Key Issues in the Success of Community-Based Management of Severe Malnutrition

Background

Acute malnutrition is an underlying factor in almost 50% of the 10 to 11 million children under 5 years of age who die each year of preventable causes. Inpatient treatment for severe acute malnutrition is associated with high opportunity and economic costs for affected families and health service providers. Community-based therapeutic care attempts to address these problems and to maximize population-level impact through improving coverage, access, and cost-effectiveness of treatment.

The community-based therapeutic care model

Community-based therapeutic care programs provide effective care to the majority of acutely malnourished people as outpatients, using techniques of community mobilization to engage the affected population and maximize coverage and compliance. People with severe acute malnutrition without medical complications are treated in an outpatient therapeutic program with ready-to-use therapeutic food and routine medication. Those suffering from severe acute malnutrition with medical complications are treated in an inpatient stabilization center according to standard World Health Organization protocols until they are well enough to be transferred to the outpatient therapeutic program.

Impact of community-based therapeutic care programs

Twenty-one (21) community-based therapeutic care programs were implemented in Malawi, Ethiopia, and North and South Sudan between 2000 and 2005. These programs, which treated 23,511 cases of severe acute malnutrition, achieved recovery rates of 79.4% and mortality rates of 4.1%. Coverage rates were approximately 73%. Of the severely malnourished children who presented, 76% were treated solely as outpatients. Initial data indicate that these programs are affordable, with the cost-effectiveness of emergency community-based therapeutic programs varying from US$12 to US$132 per year of life gained.

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.

Ready-to-use therapeutic food for home-based treatment of severe acute malnutrition in children from six months to five years of age

BACKGROUND

Malnourished children have a higher risk of death and illness. Treating severe acute malnourished children in hospitals is not always desirable or practical in rural settings, and home treatment may be better. Home treatment can be food prepared by the carer, such as flour porridge, or commercially manufactured food such as ready-to-use therapeutic food (RUTF). RUTF is made according to a standard, energy-rich composition defined by the World Health Organization (WHO). The benefits of RUTF include a low moisture content, long shelf life without needing refrigeration and that it requires no preparation.

OBJECTIVES

To assess the effects of home-based RUTF on recovery, relapse and mortality in children with severe acute malnutrition.

SEARCH METHODS

We searched the following electronic databases up to April 2013: Cochrane Central Register of Clinical Trials (CENTRAL), MEDLINE, MEDLINE In-process, EMBASE, CINAHL, Science Citation Index, African Index Medicus, LILACS, ZETOC and three trials registers. We also contacted researchers and clinicians in the field and handsearched bibliographies of included studies and relevant reviews.

SELECTION CRITERIA

We included randomised and quasi-randomised controlled trials where children between six months and five years of age with severe acute malnutrition were treated at home with RUTF compared to a standard diet, or different regimens and formulations of RUTFs compared to each other. We assessed recovery, relapse and mortality as primary outcomes, and anthropometrical changes, time to recovery and adverse outcomes as secondary outcomes.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed trial eligibility using prespecified criteria, and three review authors independently extracted data and assessed trial risk of bias.

MAIN RESULTS

We included four trials (three having a high risk of bias), all conducted in Malawi with the same contact author. One small trial included children infected with human immunodeficiency virus (HIV). We found the risk of bias to be high for the three quasi-randomised trials while the fourth trial had a low to moderate risk of bias. Because of the sparse data for HIV, we reported below the main results for all children together. RUTF meeting total daily requirements versus standard dietWhen comparing RUTF with standard diet (flour porridge), we found three quasi-randomised cluster trials (n = 599). RUTF may improve recovery slightly (risk ratio (RR) 1.32; 95% confidence interval (CI) 1.16 to 1.50; low quality evidence), but we do not know whether RUTF improves relapse, mortality or weight gain (very low quality evidence). RUTF supplement versus RUTF meeting total daily requirementsWhen comparing RUTF supplement with RUTF that meets total daily nutritional requirements, we found two quasi-randomised cluster trials (n = 210). For recovery, relapse, mortality and weight gain the quality of evidence was very low; therefore, the effects of RUTF are unknown. RUTF containing less milk powder versus standard RUTFWhen comparing a cheaper RUTF containing less milk powder (10%) versus standard RUTF (25% milk powder), we found one trial that randomised 1874 children. For recovery, there was probably little or no difference between the groups (RR 0.97; 95% CI 0.93 to 1.01; moderate quality evidence). RUTF containing less milk powder may lead to slightly more children relapsing (RR 1.33; 95% CI 1.03 to 1.72; low quality evidence) and to less weight gain (mean difference (MD) -0.5 g/kg/day; 95% CI -0.75 to -0.25; low-quality evidence) than standard RUTF. We do not know whether the cheaper RUTF improved mortality (very low quality evidence).

AUTHORS' CONCLUSIONS

Given the limited evidence base currently available, it is not possible to reach definitive conclusions regarding differences in clinical outcomes in children with severe acute malnutrition who were given home-based ready-to-use therapeutic food (RUTF) compared to the standard diet, or who were treated with RUTF in different daily amounts or formulations. For this reason, either RUTF or flour porridge can be used to treat children at home depending on availability, affordability and practicality. Well-designed, adequately powered pragmatic randomised controlled trials of HIV-uninfected and HIV-infected children with severe acute malnutrition are needed.

Effects of pneumonia and malnutrition on the frequency of micronuclei in peripheral blood of pediatric patients

The aim of this study was to evaluate the effects of bacterial pneumonia and malnutrition on the frequency of micronuclei (MN) in peripheral blood of pediatric patients through flow cytometric analysis. The study was an analytical case-control study carried out on 35 malnourished children with bacterial pneumonia and 20 well-nourished children with bacterial pneumonia, in addition to 20 healthy children as controls. Complete physical examination including; anthropometric measurement, Chest roentgenograms were done for all cases. Assessment of MN was done by FACSCalibur flow cytometry. The frequency of micronucleated reticulocytes (MN-RETs) was higher both in the malnourished children with pneumonia and well-nourished children with pneumonia than the controls. Within the malnourished children with pneumonia, patients with kwashiorkor had more micronucleated mature erythrocytes (MN-RBCs) and MN-RETs than patients with marasmus.

IN CONCLUSION

Pneumonia is associated with an increased frequency of MN and this increment is more pronounced in children with severe malnutrition especially kwashiorkor group.

Protein energy malnutrition

Protein energy malnutrition (PEM) is a common problem worldwide and occurs in both developing and industrialized nations. In the developing world, it is frequently a result of socioeconomic, political, or environmental factors. In contrast, protein energy malnutrition in the developed world usually occurs in the context of chronic disease. There remains much variation in the criteria used to define malnutrition, with each method having its own limitations. Early recognition, prompt management, and robust follow up are critical for best outcomes in preventing and treating PEM.

Joint BAPEN and Nutrition Society Symposium on 'Feeding size 0: the science of starvation'. Severe malnutrition: therapeutic challenges and treatment of hypovolaemic shock

The systematic failure to recognise and appropriately treat children with severe malnutrition has been attributed to the elevated case-fatality rates, often as high as 50%, that still prevail in many hospitals in Africa. Children admitted to Kilifi District Hospital, on the coast of Kenya, with severe malnutrition frequently have life-threatening features and complications, many of which are not adequately identified or treated by WHO guidelines. Four main areas have been identified for research: early identification and better supportive care of sepsis; evidence-based fluid management strategies; improved antimicrobial treatment; rational use of nutritional strategies. The present paper focuses on the identification of children with sepsis and on fluid management strategies.

Mortality risk among children admitted in a large-scale nutritional program in Niger, 2006

Background

In 2006, the Médecins sans Frontières nutritional program in the region of Maradi (Niger) included 68,001 children 6–59 months of age with either moderate or severe malnutrition, according to the NCHS reference (weight-for-height<80% of the NCHS median, and/or mid-upper arm circumference<110 mm for children taller than 65 cm and/or presence of bipedal edema). Our objective was to identify baseline risk factors for death among children diagnosed with severe malnutrition using the newly introduced WHO growth standards. As the release of WHO growth standards changed the definition of severe malnutrition, which now includes many children formerly identified as moderately malnourished with the NCHS reference, studying this new category of children is crucial.

Methodology

Program monitoring data were collected from the medical records of all children admitted in the program. Data included age, sex, height, weight, MUAC, clinical signs on admission including edema, and type of discharge (recovery, death, and default/loss to follow up). Additional data included results of a malaria rapid diagnostic test due to Plasmodium falciparum (Paracheck®) and whether the child was a resident of the region of Maradi or came from bordering Nigeria to seek treatment. Multivariate logistic regression was performed on a subset of 27,687 children meeting the new WHO growth standards criteria for severe malnutrition (weight-for-height<−3 Z score, mid-upper arm circumference<110 mm for children taller than 65 cm or presence of bipedal edema). We explored two different models: one with only basic anthropometric data and a second model that included perfunctory clinical signs.

Principal Findings

In the first model including only weight, height, sex and presence of edema, the risk factors retained were the weight/height^1.84 ratio (OR: 5,774; 95% CI: [2,284; 14,594]) and presence of edema (7.51 [5.12; 11.0]). A second model, taking into account supplementary data from perfunctory clinical examination, identified other risk factors for death: apathy (9.71 [6.92; 13.6]), pallor (2.25 [1.25; 4.05]), anorexia (1.89 [1.35; 2.66]), fever>38.5°C (1.83 [1.25; 2.69]), and age below 1 year (1.42 [1.01; 1.99]).

Conclusions

Although clinicians will continue to perform screening using clinical signs and anthropometry, these risk indicators may provide additional criteria for the assessment of absolute and relative risk of death. Better appraisal of the child's risk of death may help orientate the child towards either hospitalization or ambulatory care. As the transition from the NCHS growth reference to the WHO standards will increase the number of children classified as severely malnourished, further studies should explore means to identify children at highest risk of death within this group using simple and standardized indicators.

HIV prevalence and mortality among children undergoing treatment for severe acute malnutrition in sub-Saharan Africa: a systematic review and meta-analysis

This systematic review and meta-analysis explored HIV prevalence and mortality in children undergoing treatment for severe acute malnutrition (SAM) in sub-Saharan Africa. It included all studies reporting on HIV infection within a sample of children with SAM where HIV status was assessed using a blood test and SAM was defined using the WHO, Gomez, Wellcome or Waterlow definitions. Children from 17 studies were included in the analysis (n=4891), of whom 29.2% were HIV-infected. HIV-infected children were significantly more likely to die than HIV-uninfected children (30.4% vs. 8.4%; P<0.001; relative risk=2.81, 95% CI 2.04-3.87). HIV-negative children treated within community-based therapeutic care (CTC) programmes had lower mortality (4.3%) than those treated within an inpatient nutrition rehabilitation unit (NRU) (15.1%). There was no significant difference in mortality for HIV-infected children with SAM treated in the CTC (30.0%) or NRU (31.3%) settings. HIV prevalence is high in children with SAM in sub-Saharan Africa, and HIV-infected children are at significantly increased risk of mortality. There is an urgent need to integrate HIV testing and treatment into care for children with SAM in regions of high HIV prevalence.

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

BACKGROUND

In Malawi and other high HIV prevalence countries, studies suggest that more than 30% of all severely malnourished children admitted to inpatient nutrition rehabilitation units are HIV-infected. However, clinical algorithms designed to diagnose paediatric HIV are neither sensitive nor specific in severely malnourished children. The present study was conducted to assess : i) whether HIV testing can be integrated into Community-based Therapeutic Care (CTC); ii) to determine if CTC can improve the identification of HIV infected children; and iii) to assess the impact of CTC programmes on the rehabilitation of HIV-infected children with Severe Acute Malnutrition (SAM).

METHODS

This community-based cohort study was conducted in Dowa District, Central Malawi, a rural area 50 km from the capital, Lilongwe. Caregivers and children admitted in the Dowa CTC programme were prospectively (Prospective Cohort = PC) and retrospectively (Retrospective Cohort = RC) admitted into the study and offered HIV testing and counseling. Basic medical care and community nutrition rehabilitation was provided for children with SAM. The outcomes of interest were uptake of HIV testing, and recovery, relapse, and growth rates of HIV-positive and uninfected children in the CTC programme. Student's t-test and analysis of variance were used to compare means and Kruskall Wallis tests were used to compare medians. Dichotomous variables were compared using Chi2 analyses and Fisher's exact test. Stepwise logistic regression with backward elimination was used to identify predictors of HIV infection (alpha = 0.05).

RESULTS

1273 and 735 children were enrolled in the RC and PC. For the RC, the average age (SD) at CTC admission was 30.0 (17.2) months. For the PC, the average age at admission was 26.5 (13.7) months. Overall uptake of HIV testing was 60.7% for parents and 94% for children. HIV prevalence in severely malnourished children was 3%, much lower than anticipated. 59% of HIV-positive and 83% of HIV-negative children achieved discharge Weight-For-Height (WFH) > or = 80% of the NCHS reference median (p = 0.003). Clinical algorithms for diagnosing HIV in SAM children had poor sensitivity and specificity.

CONCLUSION

CTC is a potentially valuable entry point for providing HIV testing and care in the community to HIV infected children with SAM.

A comparison of the programme coverage of two therapeutic feeding interventions implemented in neighbouring districts of Malawi

Objective

To compare therapeutic feeding programme coverage for severely malnourished children achieved by a community-based therapeutic care (CTC) programme and a therapeutic feeding centre (TFC) programme operating in neighbouring districts in Malawi.

Design

Two surveys were implemented simultaneously one in each of the two programme areas. Each survey used a stratified design with strata defined using the centric systematic area sample method. Thirty 100 km2 quadrats were sampled. The community or communities located closest to the centre of each quadrat were sampled using a case-finding approach. Cases were defined as children aged under 5 years with ≤ 70% of the weight-for-height median or bilateral pitting oedema. Receipt of treatment was ascertained by the child's presence in a therapeutic feeding programme or by documentary evidence. Coverage in each quadrat was estimated in two ways, a period estimate that provides an estimation of coverage for the recent period preceding the survey and a point estimate that provides an estimation of coverage at the exact point in time of the survey.

Results

Overall the period coverage was 24.55% (95% confidence interval (CI) = 17.8–31.4%) in the TFC programme and 73.64% (95% CI = 66.0–81.3%) in the CTC programme. The point coverage was 20.04% (95% CI = 13.8–26.3%) in the TFC programme and 59.95% (95% CI = 51.4–68.5%) in the CTC programme.

Conclusions

In this context, CTC gave substantially higher programme coverage than a TFC programme. Given effective treatment, this enabled higher impact of CTC on severe malnutrition in this population.

Treating severe acute malnutrition seriously

Severe acute malnutrition (SAM) affects approximately 13 million children under the age of 5 and is associated with 1-2 million preventable child deaths each year. In most developing countries, case fatality rates (CFRs) in hospitals treating SAM remain at 20-30% and few of those requiring care actually access treatment. Recently, community-based therapeutic care (CTC) programmes treating most cases of SAM solely as outpatients have dramatically reduced CFRs and increased the numbers receiving care. CTC uses ready-to-use therapeutic foods and aims to increase access to services, promoting early presentation and compliance, thereby increasing coverage and recovery rates. Initial data indicate that this combination of centre-based and community-based care is cost effective and should be integrated into mainstream child survival programmes.

Management of severe acute malnutrition in children

Severe acute malnutrition (SAM) is defined as a weight-for-height measurement of 70% or less below the median, or three SD or more below the mean National Centre for Health Statistics reference values, the presence of bilateral pitting oedema of nutritional origin, or a mid-upper-arm circumference of less than 110 mm in children age 1-5 years. 13 million children under age 5 years have SAM, and the disorder is associated with 1 million to 2 million preventable child deaths each year. Despite this global importance, child-survival programmes have ignored SAM, and WHO does not recognise the term "acute malnutrition". Inpatient treatment is resource intensive and requires many skilled and motivated staff. Where SAM is common, the number of cases exceeds available inpatient capacity, which limits the effect of treatment; case-fatality rates are 20-30% and coverage is commonly under 10%. Programmes of community-based therapeutic care substantially reduce case-fatality rates and increase coverage rates. These programmes use new, ready-to-use, therapeutic foods and are designed to increase access to services, reduce opportunity costs, encourage early presentation and compliance, and thereby increase coverage and recovery rates. In community-based therapeutic care, all patients with SAM without complications are treated as outpatients. This approach promises to be a successful and cost-effective treatment strategy.

Home-based therapy for oedematous malnutrition with ready-to-use therapeutic food

BACKGROUND

Standard recommendations are that children with oedematous malnutrition receive inpatient therapy with a graduated feeding regimen.

AIM

To investigate exclusive home-based therapy for children with oedematous malnutrition.

METHODS

Children with oedematous malnutrition, good appetite and no complications were treated at home with ready-to-use therapeutic food (RUTF) and followed up fortnightly for up to 8 wk.

SETTING AND PARTICIPANTS

219 children aged 1-5 y with oedema enrolled in one of two therapeutic nutritional studies in Malawi in 2003-2004.

RESULTS

The overall recovery rate was 83% (182/219), and the case-fatality rate was 5% (11/219). For children with wasting and oedematous malnutrition, 65% (55/85) recovered and 7% (6/85) died. The average weight gain was 2.8+/-3.2 g/kg/d (mean+/-SD).

CONCLUSION

This preliminary observation suggests that children with oedematous malnutrition and good appetite may be successfully treated with home-based therapy; a randomized, controlled trial to evaluate this is warranted.
