Treatment of malnutrition in refugee camps

Community management of acute malnutrition (CMAM) programme in Pakistan effectively treats children with uncomplicated severe wasting

Severe wasting is the most widespread form of severe acute malnutrition, affecting an estimated 17 million children globally. This analysis assesses the effectiveness of Pakistan's community management of acute malnutrition (CMAM) programme. We conducted a retrospective case series analysis of 32,458 children aged 6–59 months who were admitted to the programme with a mid‐upper arm circumference (MUAC) < 115 mm (January 1–December 31, 2014). We found that at admission, 59.6% of the children were girls and 87.4% were in the age group 6–23 months old. While in the programme, 120 children (0.4%) died, 3,456 (10.6%) defaulted, and 28,882 (89.0%) were discharged after a mean length of stay of 69.3 ± 25.7 days. Children's mean weight gain while in the programme was 3.2 ± 2.7 g/kg body weight/day. At discharge, 28,499 children (98.7% of discharged) had recovered (MUAC ≥ 125 mm). The odds of death were significantly higher among children with weight‐for‐height (WHZ) < −3 and/or height‐for‐age (HAZ) < −2 at admission. The odds of recovery on the basis of MUAC ≥125 mm were higher among children with HAZ ≥ −2 at admission. The odds of recovery on the basis of WHZ ≥ −2 were significantly higher among children with WHZ ≥ −3 and/or HAZ < −2 at admission. Pakistan's CMAM programme is effective in achieving good survival and recovery rates. Population‐level impact could be increased by giving priority to children 6–23 months old and children with multiple anthropometric failure and by scaling up CMAM in the provinces and areas where the risk, prevalence, and/or burden of severe acute malnutrition is highest.

Proposal of a study protocol of a preliminary double-blind randomized controlled trial. Verifying effects of selenium supplementation on selenoprotein p and s genes expression in protein and mRNA levels in subjects with coronary artery disease: selenegene

Background: Selenium is the component of selenocystein amino acid, which itself is the building block of selenoproteins having diverse effects on various aspects of the human health. Among these proteins, selenoprotein P is the central to the distribution and homeostasis of selenium, and selenoprotein S as a transmembrane protein is associated with a range of inflammatory markers, particularly in the context of cardiovascular disease. It is known that selenium status outside of the normal range is considered to confer different benefits or adverse cardiovascular risk factors. Therefore, for the first time, we aimed to verify effects of Selenium supplementation on Selenoprotein P and S Genes Expression in Protein and mRNA Levels in Subjects with Coronary Artery Disease (CAD). Methods: This is the study protocol of a double blinded randomized clinical trial on 130 subjects with angiographically documented stenosis of more than 75% in one or more coronary artery vessels. In this 60-day study, 65 patients in each group received either a 200mg selenium yeast or placebo tablets once daily. During the study, subjects were followed by phone calls and visited our clinic twice to repeat baseline measurements. We hypothesized that our finding would enable a more basic and confirmed understanding for the effect of selenium supplementation by investigating its effect on gene expression levels in people with CAD. Discussion: Upon confirmation of this hypothesis, the beneficial effect of inflammation regulation by supplementation with micronutrients could be considered for subjects with CVD.

Seasonal effect and long-term nutritional status following exit from a Community-Based Management of Severe Acute Malnutrition program in Bihar, India

Background/Objectives:

Children aged 6 months to 5 years completing treatment for severe acute malnutrition (SAM) in a Médecins Sans Frontières Community Management of Acute Malnutrition (CMAM) program in Bihar, India, showed high cure rates; however, the program suffered default rates of 38%. This report describes the nutritional status of 1956 children followed up between 3 and 18 months after exiting the program.

Subjects/Methods:

All children aged 6–59 months discharged as cured with mid-upper arm circumference (MUAC) ⩾120 mm or who defaulted from the program with MUAC <115 mm were traced at 3, 6, 9, 12 and 18 months (±10 days) before three exit reference dates: first at the end of the food insecure period, second after the 2-month food security and third after the 4-month food security.

Results:

Overall, 68.7% (n=692) of defaulters and 76.2% (n=1264) of children discharged as cured were traced. Combined rates of non-recovery in children who defaulted with MUAC <115 mm were 41%, 30.1%, 9.9%, 6.1% and 3.6% at 3, 6, 9, 12 and 18 months following exit, respectively. Combined rates of relapse among cured cases (MUAC ⩾120 mm) were 9.1%, 2.9%, 2.1%, 2.8% and 0% at 3, 6, 9, 12 and 18 months following discharge, respectively. Prevalence of undernutrition increased substantially for both groups traced during low food security periods. Odds of death were much higher for children defaulting with MUAC <110 mm when compared with children discharged as cured, who shared the same mortality risk as those defaulting with MUAC 110–<115 mm.

Conclusions:

Seasonal food security predicted short-term nutritional status after exit, with relapse rates and non-recovery from SAM much higher during food insecurity. Mortality outcomes suggest that a MUAC of 110 mm may be considered an appropriate admission point for SAM treatment programs in this context.

Community-based management of severe acute malnutrition in India: new evidence from Bihar

BACKGROUND

An estimated one-third of the world's children who are wasted live in India. In Bihar state, of children <5 y old, 27.1% are wasted and 8.3% have severe acute malnutrition (SAM). In 2009, Médecins Sans Frontières (MSF) initiated a community-based management of acute malnutrition (CMAM) program for children aged 6-59 mo with SAM.

OBJECTIVE

In this report, we describe the characteristics and outcomes of 8274 children treated between February 2009 and September 2011.

DESIGN

Between February 2009 and June 2010, the program admitted children with a weight-for-height z score (WHZ) <-3 SD and/or midupper arm circumference (MUAC) <110 mm and discharged those who reached a WHZ >-2 SDs and MUAC >110 mm. These variables changed in July 2010 to admission on the basis of an MUAC <115 mm and discharge at an MUAC ≥120 mm. Uncomplicated SAM cases were treated as outpatients in the community by using a WHO-standard, ready-to-use, therapeutic lipid-based paste produced in India; complicated cases were treated as inpatients by using F75/F100 WHO-standard milk until they could complete treatment in the community.

RESULTS

A total of 8274 children were admitted including 5149 girls (62.2%), 6613 children aged 6-23 mo (79.9%), and 87.3% children who belonged to Scheduled Caste, Scheduled Tribe, or Other Backward Caste families or households. Of 3873 children admitted under the old criteria, 41 children (1.1%) died, 2069 children (53.4%) were discharged as cured, and 1485 children (38.3%) defaulted. Of 4401 children admitted under the new criteria, 36 children (0.8%) died, 2526 children (57.4%) were discharged as cured, and 1591 children (36.2%) defaulted. For children discharged as cured, the mean (±SD) weight gain and length of stay were 4.7 ± 3.1 and 5.1 ± 3.7 g · kg(-1) · d(-1) and 8.7 ± 6.1 and 7.3 ± 5.6 wk under the old and new criteria, respectively (P < 0.01). After adjustment, significant risk factors for default were as follows: no community referral for admission, more severe wasting on admission, younger age, and a long commute for treatment.

CONCLUSIONS

To our knowledge, this is the first conventional CMAM program in India and has achieved low mortality and high cure rates in nondefaulting children. The new admission criteria lower the threshold for severity with the result that more children are included who are at lower risk of death and have a smaller WHZ deficit to correct than do children identified by the old criteria. This study was registered as a retrospective observational analysis of routine program data at http://www.isrctn.com as ISRCTN13980582.

Integrated program achieves good survival but moderate recovery rates among children with severe acute malnutrition in India

BACKGROUND

At any point in time, an average 8 million Indian children suffer from severe acute malnutrition (SAM).

OBJECTIVE

This article assesses the effectiveness of an integrated model for the management of SAM (IM-SAM) in India comprising facility- and community-based care and using locally adapted protocols.

DESIGN

Children (n = 2740) were randomly sampled from the 44,017 children aged 6-59 mo admitted to 199 Nutrition Rehabilitation Centers in the state of Madhya Pradesh (1 January to 31 December 2010).

RESULTS

On admission, 2.2% of children had edema, 23.4% had medical complications, 56% were girls, 79% were in the age group 6-23 mo, and 64% belonged to scheduled tribe or scheduled caste families. Fifty-six children (2.0%) with severe congenital or pathological conditions were transferred to the district hospital. Of the 2684 program exits, 10 children (0.4%) died, 860 (32.0%) did not complete treatment (defaulted), and 1814 (67.6%) were discharged after a mean (±SD) stay of 75.8 ± 9.4 d. The mean weight gain among discharged children was 2.7 ± 1.9 g · kg body wt(-1) · d(-1); on discharge, 1179 (65%) of the children had recovered (weight gain ≥15% of initial weight).

CONCLUSIONS

The survival rates in the IM-SAM program were very high. However, the moderate recovery rates documented seem to indicate that the protocols currently in use need to be improved. This trial was registered at clinicaltrials.gov as NCT01917734.

Do children with uncomplicated severe acute malnutrition need antibiotics? A systematic review and meta-analysis

BACKGROUND

Current (1999) World Health Organization guidelines recommend giving routine antibiotics (AB) for all children with severe acute malnutrition (SAM), even if they have uncomplicated disease with no clinically obvious infections. We examined the evidence behind this recommendation.

METHODS AND FINDINGS

OVID-MEDLINE, EMBASE, COCHRANE, GLOBAL-HEALTH, CINAHL, POPLINE, AFRICA-WIDE-NiPAD, and LILACS were searched for AB efficacy, bacterial resistance, and infection rates in SAM. Following PRISMA guidelines, a systematic review and meta-analysis were performed. Three randomised controlled trials (RCT), five Cochrane reviews, and 37 observational studies were identified. One cohort-study showed no increase in nutritional-cure and mortality in uncomplicated SAM where no AB were used. (p>0.05). However, an unpublished RCT in this setting did show mortality benefits. Another RCT did not show superiority of ceftriaxone over amoxicilllin for these same outcomes, but adressed SAM children with and without complications (p = 0.27). Another RCT showed no difference between amoxicillin and cotrimoxazole efficacies for pneumonia in underweight, but not SAM. Our meta-analysis of 12 pooled susceptibility-studies for all types of bacterial isolates, including 2767 stricly SAM children, favoured amoxicillin over cotrimoxazole for susceptibility medians: 42% (IQR 27-55%) vs 22% (IQR 17-23%) and population-weighted-means 52.9% (range 23-57%) vs 35.4% (range 6.7-42%). Susceptibilities to second-line AB were better, above 80%. Prevalence of serious infections in SAM, pooled from 24 studies, ranged from 17% to 35.2%. No study infered any association of infection prevalence with AB regimens in SAM.

CONCLUSIONS

The evidence underlying current antibiotic recommendations for uncomplicated SAM is weak. Susceptibility-studies favour amoxicillin over cotrimoxazole. However, given that these antibiotics have side-effects, costs, and risks as well as benefits, their routine use needs urgent testing. With reliable monitoring, we believe that there is sufficient equipoise for placebo controlled RCTs, the only robust way to demonstrate true efficacy.

Community management of acute malnutrition in the developing world

Globally, acute malnutrition triggers more than 50% of childhood mortality in children under 5 years old, which implies that about 3.5 million children die of malnutrition each year. Prior to the advent of ready-to-use therapeutic food (RUTF), the management of acute malnutrition was limited to hospitals, resulting in low coverage rates with high mortality, as malnourished cases were indentified at later stages often plagued with complications. However, current availability of RUTF has enabled malnourished children to be treated at communities. Further, because RUTF is dehydrated and sealed, it has the added advantage of a lower risk of bacterial contamination, thereby prolonging its storage life at room temperature. Recent data indicate that Community Management of Acute Malnutrition (CMAM) is as cost effective as other high-impact public health measures such as oral rehydration therapy for acute diarrheal diseases, vitamin A supplementation, and antibiotic treatment for acute respiratory infections. Despite the high efficacy of CMAM programs, CMAM still draws insufficient attention for global implementation, suggesting that CMAM programs should be integrated into local or regional routine health systems. Knowledge gaps requiring further research include: the definition of practical screening criteria for malnourished children at communities, the need for systematic antibiotic therapy during malnutrition treatment, and the dietary management of severe malnutrition in children below 6 months of age.

Effect of mass supplementation with ready-to-use supplementary food during an anticipated nutritional emergency

Background

Previous studies have shown the benefits of ready-to-use supplementary food (RUSF) distribution in reducing the incidence and prevalence of severe acute malnutrition.

Methods and Findings

To compare the incidence of wasting, stunting and mortality between children aged 6 to 23 mo participating and not participating in distributions of RUSF, we implemented two exhaustive prospective cohorts including all children 60 cm to 80 cm, resident in villages of two districts of Maradi region in Niger (n = 2238). Villages (20) were selected to be representative of the population. All registered children were eligible for the monthly distributions between July and October 2010. Age, sex, height, weight, and Mid-Upper Arm Circumference (MUAC) were measured at baseline and two weeks after each distribution; the amount and type of distribution and the amount shared and remaining were also assessed. We compared the incidence of wasting, stunting, and mortality among children participating in the distribution (intervention) of RUSF versus children not participating in the distribution (comparison). The absolute rate of wasting was 4.71 events per child-year (503 events/106.59 child-year) in the intervention group and 4.98 events per child-year (322 events/64.54 child-year) in the comparison group. The intervention group had a small but higher weight-for-length Z-score gain (−0.2z vs. −0.3z) and less loss of MUAC than the comparison group (−2.8 vs. −4.0 mm). There was no difference in length gain (2.7 vs. 2.8 cm). Mortality was lower for children whose households received the intervention than those who did not (adjusted HR 0.55, 95% CI: 0.32–0.98).

Conclusions

Short-term distribution with RUSF for children 6 to 23 months improve the nutritional status of children at risk for malnutrition. Fewer children who participated in the RUSF distribution died than those who did not.

Proposed Recommended Nutrient Densities for Moderately Malnourished Children

Recommended Nutrient Intakes (RNIs) are set for healthy individuals living in clean environments. There are no generally accepted RNIs for those with moderate malnutrition, wasting, and stunting, who live in poor environments. Two sets of recommendations are made for the dietary intake of 30 essential nutrients in children with moderate malnutrition who require accelerated growth to regain normality: first, for those moderately malnourished children who will receive specially formulated foods and diets; and second, for those who are to take mixtures of locally available foods over a longer term to treat or prevent moderate stunting and wasting. Because of the change in definition of severe malnutrition, much of the older literature is pertinent to the moderately wasted or stunted child. A factorial approach has been used in deriving the recommendations for both functional, protective nutrients (type I) and growth nutrients (type II).

Malnutrition and health in developing countries

Malnutrition, with its 2 constituents of protein-energy malnutrition and micronutrient deficiencies, continues to be a major health burden in developing countries. It is globally the most important risk factor for illness and death, with hundreds of millions of pregnant women and young children particularly affected. Apart from marasmus and kwashiorkor (the 2 forms of protein- energy malnutrition), deficiencies in iron, iodine, vitamin A and zinc are the main manifestations of malnutrition in developing countries. In these communities, a high prevalence of poor diet and infectious disease regularly unites into a vicious circle. Although treatment protocols for severe malnutrition have in recent years become more efficient, most patients (especially in rural areas) have little or no access to formal health services and are never seen in such settings. Interventions to prevent protein- energy malnutrition range from promoting breast-feeding to food supplementation schemes, whereas micronutrient deficiencies would best be addressed through food-based strategies such as dietary diversification through home gardens and small livestock. The fortification of salt with iodine has been a global success story, but other micronutrient supplementation schemes have yet to reach vulnerable populations sufficiently. To be effective, all such interventions require accompanying nutrition-education campaigns and health interventions. To achieve the hunger- and malnutrition-related Millennium Development Goals, we need to address poverty, which is clearly associated with the insecure supply of food and nutrition.

Outpatient care for severely malnourished children in emergency relief programmes: a retrospective cohort study

BACKGROUND

In emergency nutritional relief programmes, therapeutic feeding centres are the accepted intervention for the treatment of severely malnourished people. These centres often cannot treat all the people requiring care. Consequently, coverage of therapeutic feeding centre programmes can be low, reducing their effectiveness. We aimed to assess the effectiveness of outpatient treatment for severe malnutrition in an emergency relief programme.

METHODS

We did a retrospective cohort study in an outpatient therapeutic feeding programme in Ethiopia from September, 2000, to January, 2001. We assessed clinical records for 170 children aged 6-120 months. The children had either marasmus, kwashiorkor, or marasmic kwashiorkor. Outcomes were mortality, default from programme, discharge from programme, rate of weight gain, and length of stay in programme.

FINDINGS

144 (85%) patients recovered, seven (4%) died, 11 (6%) were transferred, and eight (5%) defaulted. Median time to discharge was 42 days (IQR 28-56), days to death 14 (7-26), and days to default 14 (7-28). Median rate of weight gain was 3.16 g kg(-1) x day(-1) (1.86-5.60). In patients who recovered, median rates of weight gain were 4.80 g kg(-1) day(-1) (2.95-8.07) for marasmic patients, 4.03 g x kg(-1) x day(-1) (2.68-4.29) for marasmic kwashiorkor patients, and 2.70 g x kg(-1) x day(-1) (0.00-4.76) for kwashiorkor patients.

INTERPRETATION

Outpatient treatment exceeded internationally accepted minimum standards for recovery, default, and mortality rates. Time spent in the programme and rates of weight gain did not meet these standards. Outpatient care could provide a complementary treatment strategy to therapeutic feeding centres. Further research should compare the effectiveness of outpatient and centre-based treatment of severe malnutrition in emergency nutritional interventions.

Food aid in emergencies: a case for wheat?

As disasters and conflict increase, a higher proportion of total food aid is given as humanitarian aid. Most food aid is in the form of cereals, primarily wheat. The main donors are the USA and the EU, but there is an increase in the numbers of donors, including non-governmental organizations, buying food rather than using surpluses. Alongside the greater diversity and complexity of food aid, there is more controversy about policy and practice. If disasters are development failures, emergency food aid must be a step in the continuum from relief to rehabilitation. Comparisons of the seventeen countries that were major recipients of food aid (> 10,000 t) in 1997, show diversity in social development, dietary pattern, number of refugees, relative food inadequacy and wasting (i.e. % standard weight-for-height > 2 SD). In the absence of information of consistent quality, what influences the scale of emergency aid is unclear and susceptible to politicization, so that need and supply may not be matched. Local considerations seem to be as important as external food aid for the nutrition of the recipients. Challenges for the future include assuring the nutritional quality of rations to solve deficiency problems. The implications for the professional public health nutritionist working on emergency food provision include continuing professional development to enhance the technical expertise necessary to design appropriate feeds or rations. These public health nutritionists, more than others, require a grounding in social science theories that underpin management, ethics of professionalism and the politics of food aid.

Protein-energy interactions in the management of severemalnutrition

The three syndromes of childhood malnutrition are contrasted with respect to protein. It is concluded that stunting and wasting are the outcomes of protein deficiency, and that kwashiorkor is not due to protein deficiency, rather it is related to unopposed oxidant stress. Formula for the energy and protein requirements are derived and contour plots of the amounts needed to sustain high rates of weight gain at different body compositions generated. It is suggested that all nutrients be expressed with energy as the denominator. No more than 12.5% of protein energy is required to sustain maximum likely rates of weight gain. Using this approach to design a diet, high rates of weight gain are achieved under field conditions in refugee camps.

Potassium supplementation in kwashiorkor

BACKGROUND

Kwashiorkor is an edimatous form of severe malnutrition and is the predominant form of childhood malnutrition in Malawi. Potassium depletion is common and contributes to the high mortality. The aim of this study was to determine if high potassium supplementation improves the outcome of kwashiorkor treatment.

METHODS

We performed a randomised, double-blind, placebo-controlled, clinical trial of high potassium supplementation in 99 children with kwashiorkor. Controls (n = 51) received a standard potassium intake of 4.7 mmol/kg/day. The intervention group (n = 48) received 7.7 mmol/kg/day. All cases (intervention and control groups) were treated in the hospital-based Nutrition Rehabilitation Center and received a standard treatment regime of mild feeds, mineral and vitamin supplements, and antibiotics.

RESULTS

There was no significant difference in length of hospitalization, or time for resolution of oedema between groups. The case-fatality rate was reduced by 33% in the high potassium intervention group (13/48) compared to controls (21/51). There was a significant reduction in late deaths (13 in controls vs 3 in intervention group; odds ratio 5.3, 95% confidence interval 1.2-31.0) but no difference in early deaths (0-5 days). The intervention group also had significantly fewer presumed septic episodes (3 vs 18, odds ratio 8.9, confidence interval 2.2-50.9), respiratory symptoms, and new skin ulcerations than controls.

CONCLUSIONS

The high potassium supplementation reduced mortality and significant morbidity in kwashiorkor. This may be due to improved myocardial and immune function from earlier repletion of intracellular potassium. We recommend that the standard potassium supplement for the initial phase of treatment of kwashiorkor be increased from 4 to 8 mmol/kg/day.
