RESUMEN
BACKGROUND & AIMS: Change in hydration is common in children with severe acute malnutrition (SAM) including during treatment, but is difficult to assess. We investigated the utility of bio-electrical impedance vector analysis (BIVA), a quick non-invasive method, for indexing hydration during treatment. METHODS: We studied 350 children 0·5-14 years of age with SAM (mid-upper arm circumference <11·0 cm or weight-for-height <70% of median, and/or nutritional oedema) admitted to a hospital nutrition unit, but excluded medically unstable patients. Weight, height (H), resistance (R), reactance (Xc) and phase angle (PA) were measured and oedema assessed. Similar data were collected from 120 healthy infants and preschool/school children for comparison. Means of height-adjusted vectors (R/H, Xc/H) from SAM children were interpreted using tolerance and confidence ellipses of corresponding parameters from the healthy children. RESULTS: SAM children with oedema were less wasted than those without (p < 0·001), but had BIVA parameters that differed more from those of healthy children (P < 0·05) than those non-oedematous. Initially, both oedematous and non-oedematous SAM children had mean vectors outside the reference 95% tolerance ellipse. During treatment, mean vectors migrated differently in the two SAM groups, indicating fluid loss in oedematous patients, and tissue accretion in non-oedematous patients. At admission, R/H was lower (oedematous) or higher (non-oedematous) among children who died than those who exited the hospital alive. CONCLUSIONS: BIVA can be used in children with SAM to distinguish tissue-vs. hydration-related weight changes during treatment, and also identify children at high risk of death enabling early clinical interventions.

BACKGROUND & AIMS: Severe Acute Malnutrition (SAM) in children is determined using anthropometry. However, bio-electrical impedance (BI) analysis could improve the estimation of altered body composition linked to edema and/or loss of lean body mass in children with SAM. We aimed to assess: 1) the changes in BI parameters during clinical stabilization and 2) whether BI parameters add prognostic value for clinical outcome beyond the use of anthropometry. METHODS: This prospective observational study enrolled children, aged 6-60 months, that were admitted at Queen Elizabeth Central Hospital in Blantyre, Malawi, for complicated SAM (i.e., having either severe wasting or edematous SAM with a complicating illness). Height, weight, mid-upper arm circumference (MUAC), and BI were measured on admission and after clinical stabilization. BI measures were derived from height-adjusted indices of resistance (R/H), reactance (Xc/H), and phase angle (PA) and considered to reflect body fluids and soft tissue in BI vector analysis (BIVA). RESULTS: We studied 183 children with SAM (55% edematous; age 23.0 ± 12.0 months; 54% male) and 42 community participants (age 20.1 ± 12.3 months; male 62%). Compared to community participants, the BIVA of children with edematous SAM were short with low PA and positioned low on the hydration axis which reflects severe fluid retention. In contrast, children with severe wasting had elongated vectors with a PA that was higher than children with edematous SAM but lower than community participants. Their BIVA position fell within the top right quadrant linked to leanness and dehydration. BIVA from severely wasted and edematous SAM patients differed between groups and from community children both at admission and after stabilization (p < 0.001). Vector position shifted during treatment only in children with edematous SAM (p < 0.001) and showed a upward translation suggestive of fluid loss. While PA was lower in children with SAM, PA did not contribute more than anthropometry alone towards explaining mortality, length of stay, or time-to-discharge or time-to-mortality. The variability and heterogeneity in BI measures was high and their overall added predictive value for prognosis of individual children was low. CONCLUSIONS: BIVA did not add prognostic value over using anthropometry alone to predict clinical outcome. Several implementation challenges need to be optimized. Thus, in low-resource settings, the routine use of BI in the management of pediatric malnutrition is questionable without improved implementation.

INTRODUCTION: Little is known about the outcomes of subjects with a history of severe acute malnutrition (SAM). We therefore sought to explore the long-term effects of SAM during childhood on human capital in adulthood in terms of education, cognition, self-esteem and health-related disabilities in daily living. METHODOLOGY: We traced 524 adults (median age of 22) in the eastern Democratic Republic of the Congo, who were treated for SAM during childhood at Lwiro hospital between 1988 and 2007 (median age 41 months). We compared them with 407 community controls of comparable age and sex. Our outcomes of interest were education, cognitive function [assessed using the Mini Mental State Examination (MMSE) for literate participants, or its modified version created by Ertan et al. (MMSE-I) for uneducated participants], self-esteem (measured using the Rosenberg Self-Esteem Scale) and health-related social and functional disabilities measured using the World Health Organization Disability Assessment Schedule (WHODAS). For comparison, we used the Chi-squared test along with the Student's t-test for the proportions and means respectively. RESULTS: Compared with the community controls, malnutrition survivors had a lower probability of attaining a high level of education (p < 0.001), of reporting a high academic performance (p = 0.014) or of having high self-esteem (p = 0.003). In addition, malnutrition survivors had an overall mean score in the cognitive test that was lower compared with the community controls [25.6 compared with 27.8, p = 0.001 (MMSE) and 22.8 compared with 26.3, p < 0.001(MMSE-I)] and a lower proportion of subjects with a normal result in this test (78.0% compared with 90.1%, p < 0.001). Lastly, in terms of health-related disabilities, unlike the community controls, malnutrition survivors had less social disability (p = 0.034), but no difference was observed as regards activities of daily living (p = 0.322). CONCLUSION: SAM during childhood exposes survivors to low human capital as regards education, cognition and behaviour in adulthood. Policy-deciders seeking to promote economic growth and to address various psychological and medico-social disorders must take into consideration the fact that appropriate investment in child health as regards SAM is an essential means to achieve this.

BACKGROUND & AIMS: Treatment of children with uncomplicated severe acute malnutrition (SAM) is based on ready-to-use therapeutic foods (RUTF) prescribed based on body weight and administered at home. Treatment performance is typically monitored through weight gain. We previously reported that a reduced dose of RUTF resulted in weight gain velocity similar to standard dose. Here we investigate the change in body composition of children treated for SAM and compare it to community controls, and describe the effect of a reduced RUTF dose on body composition at recovery. METHODS: Body composition was measured via bio-electrical impedance analysis at admission and recovery among a sub-group of children with SAM participating in a clinical trial and receiving a reduced or a standard dose of RUTF. Non-malnourished children were measured to represent community controls. Linear mixed regression models were fitted. RESULTS: We obtained body composition data from 452 children at admission, 259 at recovery and 97 community controls. During SAM treatment the average weight increased by 1.20 kg of which 0.55 kg (45%) was fat-free mass (FFM) and 0.67 kg (55%) was fat mass (FM). At recovery, children treated for SAM had 1.27 kg lower weight, 0.38 kg lower FFM, and 0.90 kg lower FM compared to community controls. However, their fat-free mass index (FFMI) was not different from community controls (Δ0.2 kg/m2; 95% CI -0.1, 0.4). No differences were observed in FFM, FM or fat mass index (FMI) between the study arms at recovery. However, FFMI was 0.35 kg/m2 higher at recovery with the reduced compared to standard dose (p = 0.007) due to slightly lower height (Δ0.22 cm; p = 0.25) and higher FFM (Δ0.11 kg; p = 0.078) in the reduced dose group. CONCLUSIONS: Almost half of the weight gain during SAM treatment was FFM. Compared to community controls, children recovered from SAM had a lower FM while their height-adjusted FFM was similar. There was no evidence of a differential effect of a reduced RUTF dose on the tissue accretion of treated children when compared to standard treatment.

BACKGROUND: Pneumonia is the leading cause of death among children globally. Most pneumonia deaths in low-income and middle-income countries (LMICs) occur among children with HIV infection or exposure, severe malnutrition, or hypoxaemia despite antibiotics and oxygen. Non-invasive bubble continuous positive airway pressure (bCPAP) is considered a safe ventilation modality that might improve child pneumonia survival. bCPAP outcomes for high-risk African children with severe pneumonia are unknown. Since most child pneumonia hospitalisations in Africa occur in non-tertiary district hospitals without daily physician oversight, we aimed to examine whether bCPAP improves severe pneumonia mortality in such settings. METHODS: This open-label, randomised, controlled trial was done in the general paediatric ward of Salima District Hospital, Malawi. We enrolled children aged 1-59 months old with WHO-defined severe pneumonia and either HIV infection or exposure, severe malnutrition, or an oxygen saturation of less than 90%. Children were randomly assigned 1:1 to low-flow nasal cannula oxygen or nasal bCPAP. Non-physicians administered care; the primary outcome was hospital survival. Primary analyses were by intention-to-treat and interim and adverse events analyses per protocol. This trial is registered with ClinicalTrials.gov, number NCT02484183, and is closed. FINDINGS: We screened 1712 children for eligibility between June 23, 2015, and March 21, 2018. The data safety and monitoring board stopped the trial for futility after 644 of the intended 900 participants were enrolled. 323 children were randomly assigned to oxygen and 321 to bCPAP. 35 (11%) of 323 children who received oxygen died in hospital, as did 53 (17%) of 321 who received bCPAP (relative risk 1·52; 95% CI 1·02-2·27; p=0·036). 13 oxygen and 17 bCPAP patients lacked hospital outcomes and were considered lost to follow-up. Suspected adverse events related to treatment occurred in 11 (3%) of 321 children receiving bCPAP and 1 (<1%) of 323 children receiving oxygen. Four bCPAP and one oxygen group deaths were classified as probable aspiration episodes, one bCPAP death as probable pneumothorax, and six non-death bCPAP events included skin breakdown around the nares. INTERPRETATION: bCPAP treatment in a paediatric ward without daily physician supervision did not reduce hospital mortality among high-risk Malawian children with severe pneumonia, compared with oxygen. The use of bCPAP within certain patient populations and non-intensive care settings might carry risk that was not previously recognised. bCPAP in LMICs needs further evaluation before wider implementation for child pneumonia care.

BACKGROUND: Malnutrition is a major contributor to the global disease burden, accounting for more than one-third of child deaths worldwide. Severe Acute Malnutrition is a disease that is an underlying condition in many under five admissions in the study area of Hiwot Fana Specialized University Hospital, Harare and in Ethiopia as a whole. OBJECTIVE: The main objective of the study is to identify the prevalent cause of mortality in Severe Acute Malnutrition, among children aged 6-59 months, admitted to Hiwot Fana Specialized University Hospital, Pediatric ward, Nutrition Rehabilitation Unit from 2013 to 2015. Which will be key to help improve the management protocol so as to see better outcomes in the patients in the study area, or at the very least to be a stepping stone to and point out the need for further analytical studies on the topic. METHODOLOGY: The study was a retrospective, descriptive cross-sectional study which was conducted to identify the prevalent causes of mortality in patients aged 6-59 months admitted to Hiwot Fana Specialized University Hospital, Nutrition Rehabilitation Unit over the period of 2013-2015. RESULTS: The study reveals that the case recovery rate of the study area is 36% with the rate of patients who have disappeared or had left against physician's advice being a whapping 61.9%. The mortality rate weez was found to be 2.1% with the mortality sex ratio of Male: Female 1.6:1. The commonest complication that appears to related with mortality in Severe Acute Malnutrition was diarrheal disease (Acute Gastroenteritis) being present in 14 of the 15 deaths in the study period. CONCLUSION: The study concludes that the Case Fatality Rate of the study area, even though very low, the high rate of disappearance and yet a comparatively low rate of recovery brings to question the general quality of care in the facility. More to this the commonest complication associated with mortality being a preventable and manageable one i.e. AGE calls for Vigilance in the management of such patients.

BACKGROUND: More children are now surviving severe acute malnutrition (SAM), but evidence suggests that early-life malnutrition is associated with increased risk of long-term cardio-metabolic disorders. To better understand potential mechanisms, we studied the metabolite profiles of children seven years after treatment for SAM. METHODS: We followed-up children (nâ¯=â¯352) treated for SAM in 2006-2007, at Queen Elizabeth Central Hospital, in Malawi. Using nuclear magnetic resonance spectroscopy, tandem mass spectrometry and enzyme-linked immunosorbent assay, we measured circulating metabolites in fasting blood in a subset of SAM survivors (nâ¯=â¯69, 9·6⯱â¯1·6â¯years), siblings (nâ¯=â¯44, 10·5⯱â¯2·7â¯years), and age and sex-matched community controls (nâ¯=â¯37, 9·4⯱â¯1·8â¯years). Data were analysed using univariate and sparse partial least square (sPLS) methods. Differences associated with SAM survival, oedema status, and anthropometry were tested, adjusting for age, sex, HIV, and wealth index. FINDINGS: Based on 194 measured metabolites, the profiles of SAM survivors were similar to those of siblings and community controls. IGF1, creatinine, and FGF21, had loading values >0·3 and ranked stably in the top 10 distinguishing metabolites, but did not differ between SAM survivors and controls with univariate analysis. Current stunting was associated with IGF1 (ßâ¯=â¯15·2, SEâ¯=â¯3·5, partial R2â¯=â¯12%, pâ¯<â¯0·0001) and this relationship could be influenced by early childhood SAM (ßâ¯=â¯17·4, SEâ¯=â¯7·7, partial R2â¯=â¯2·8%, pâ¯=â¯0·025). No metabolites were associated with oedema status, duration of hospital stay, anthropometry measured during hospitalization, nor with changes in anthropometry since hospitalization. INTERPRETATION: In this group of survivors, SAM was not associated with longer-term global metabolic changes 7â¯years after treatment. However, SAM may influence the relationship between current stunting and IGF1. Further risk markers for NCDs in SAM survivors may only be revealed by direct metabolic challenge or later in life.

BACKGROUND: The outpatient therapeutic feeding program is one dimension of the Community Based Management of Acute Malnutrition (CMAM) that provides screening, diagnostic and treatment services for children with Severe Acute Malnutrition (SAM). However, little is known about the program outcomes and factors affecting time to recovery. OBJECTIVES: To determine median time of recovery and associated factors among under-five children with SAM treated at outpatient therapeutic feeding unit in Dire Dawa, Eastern Ethiopia from January 1st, 2013 to December 31st, 2016. METHODS: A facility-based retrospective cohort study supplemented with qualitative inquiry was conducted to analyze the records of 713 under-5 children with SAM that were randomly selected from four health centers and one hospital in Dire Dawa. In-depth interviews were conducted with five health professionals. Data was collected from the nutrition registration log book by using structured check lists. The collected data were entered into EPI-data version 3.1 software and exported to SPSS version 23 for analysis using Kaplan Meir and Cox proportional hazard regression. RESULTS: The overall recovery rate was 569 (79.8%). Eighty (11.2%) defaulted, 27 (3.8%) were non-responders, 4 (0.6%) died and 15 (2.1%) were transferred-out. The median recovery time was 8.7 weeks (IQR: 5.0-14 weeks). Children with an admission weight of ≥7kg (AHR = 1.73, 95% CI: (1.41-2.14), children who were dewormed (AHR = 1.44, 95% CI: (1.01-2.06) and children with weight gain of ≥8g/kg/day (AHR = 5.76, 95% CI: (4.51-7.38) had higher probability of recovering faster. However, marasmic children stayed longer in treatment (AHR = 0.51, 95% CI: (0.37-0.71) and a low Plumpy Nut consumption rate (g/day) (AHR = 0.79) was associated with longer time of stay on treatment. CONCLUSION: The recovery rate was within the level specified in the Sphere International standards which is >75%. A higher weight at admission, taking deworming and a steady weight gain were positively associated with a fast recovery time. Appropriate nutritional therapy and management of SAM as per the national protocol will be helpful to overcome lower weight gain and higher length of stay on treatment.

OBJECTIVE: This cross sectional study was done to assess the developmental status in children (6-30 mo old) with severe acute malutrition (SAM). METHODS: Study subjects were enrolled from children in SAM therapeutic unit, and controls were selected from well-baby clinic of the institute. Neurodevelopment of both groups was assessed using the Developmental assessment scale of Indian infants (DASII). Developmental quotient (DQ) ≤70 was considered delayed. RESULTS: Mean (SE) motor DQ 59.04 (0.74) and mental DQ 62.1 (0.57) was lower in SAM as compared to controls (both P<0.0001). Clusters of early age were normal but clusters with items of later infancy were delayed. CONCLUSION: Children with SAM show significant delay in development, and motor DQ is affected more than mental DQ.

OBJECTIVE: We aimed to assess outcomes [rates of recovery, default, case fatality; rate of weight gain and rate of Mean Upper Arm Circumference (MUAC) gain] of children aged 6-59 months with severe acute malnutrition (SAM) at the Outpatient Therapeutic Center at Gado Refugee Camp, Cameroon, in relation to international standards. We retrospectively analysed files of 254 children with SAM aged 6-59 months admitted from April 2015 to August 2016. RESULTS: 72.8% got discharged as recovered, 0.8% died and none defaulted. 26.8% got referred to stabilization center, mostly for poor weight gain (44.1%). Mean rate of weight gain was 4.4 g/kg/day and MUAC gain 0.3 mm/cm/day; median duration of treatment 44.5 days. Amongst those with marasmus, kwashiorkor and marasmic kwashiorkor, median duration of stay was 48, 24.5 and 36.3 days (p = 0.002); recovery rates were similar 73, 71.4, 71.4% respectively (p = 0.7); Median rates of weight gain, 4.4, 6.7 and 8.1 g/kg/day (p = 0.05). 49 children had been incorrectly diagnosed and treated as SAM. International Standards were met in terms of case fatality rate and default rate but not rates of recovery and weight gain. Separate gender charts must be used to calculate weight for height z scores as combined charts cause significant errors.

Early nutritional insults may increase risk of adult lung disease. We aimed to quantify the impact of severe acute malnutrition (SAM) on spirometric outcomes 7â years post-treatment and explore predictors of impaired lung function.Spirometry and pulse oximetry were assessed in 237 Malawian children (median age: 9.3â years) who had been treated for SAM and compared with sibling and age/sex-matched community controls. Spirometry results were expressed as z-scores based on Global Lung Function Initiative reference data for the African-American population.Forced expiratory volume in 1â s (FEV1) and forced vital capacity (FVC) were low in all groups (mean FEV1 z-score: -0.47 for cases, -0.48 for siblings, -0.34 for community controls; mean FVC z-score: -0.32, -0.38, and -0.15 respectively). There were no differences in spirometric or oximetry outcomes between SAM survivors and controls. Leg length was shorter in SAM survivors but inter-group sitting heights were similar. HIV positive status or female sex was associated with poorer FEV1, by 0.55 and 0.31 z-scores, respectively.SAM in early childhood was not associated with subsequent reduced lung function compared to local controls. Preservation of sitting height and compromised leg length suggest "thrifty" or "lung-sparing" growth. Female sex and HIV positive status were identified as potentially high-risk groups.

PURPOSE OF REVIEW: The mortality and morbidity associated with severe acute malnutrition (SAM) remain high. A summary of recent studies that are of interest to clinicians treating children with SAM is provided. RECENT FINDINGS: Three important themes emerged in 2015: the use of anthropometry in the diagnosis of SAM and its correlation with body composition; the composition of ready-to-use therapeutic feeds (RUTF); and an improved understanding of the pathophysiology of SAM. SUMMARY: Standard anthropometry does not accurately predict body composition and mid-upper arm circumference more accurately reflects fat mass in children. As single measure, mid-upper arm circumference identifies those children who are most likely to die from SAM and is not influenced by dehydration. However, a significant proportion of SAM children requiring treatment will not be detected. Present RUTF formulations are deficient in long chain polyunsaturated fatty acids. Current evidence suggests that preformed docosahexaenoic acid should be added and/or the content of linoleic acid reduced in RUTF. In contrast to an animal model, stabile children with SAM have the same cardiac index as children without SAM. The situation in haemodynamically unstable children is unknown, continued conservative use of intravenous fluids seems advisable. A reduction in variability of the faecal DNA virome may account for increased susceptibility to malnutrition in vulnerable children.

BACKGROUND: High-quality evidence supporting a community-based treatment protocol for children with severe acute malnutrition, including routine antibiotic use at admission to a nutritional treatment program, remains limited. In view of the costs and consequences of emerging resistance associated with routine antibiotic use, more evidence is required to support this practice. METHODS: In a double-blind, placebo-controlled trial in Niger, we randomly assigned children who were 6 to 59 months of age and had uncomplicated severe acute malnutrition to receive amoxicillin or placebo for 7 days. The primary outcome was nutritional recovery at or before week 8. RESULTS: A total of 2412 children underwent randomization, and 2399 children were included in the analysis. Nutritional recovery occurred in 65.9% of children in the amoxicillin group (790 of 1199) and in 62.7% of children in the placebo group (752 of 1200). There was no significant difference in the likelihood of nutritional recovery (risk ratio for amoxicillin vs. placebo, 1.05; 95% confidence interval [CI], 0.99 to 1.12; P=0.10). In secondary analyses, amoxicillin decreased the risk of transfer to inpatient care by 14% (26.4% in the amoxicillin group vs. 30.7% in the placebo group; risk ratio, 0.86; 95% CI, 0.76 to 0.98; P=0.02). CONCLUSIONS: We found no benefit of routine antibiotic use with respect to nutritional recovery from uncomplicated severe acute malnutrition in Niger. In regions with adequate infrastructure for surveillance and management of complications, health care facilities could consider eliminating the routine use of antibiotics in protocols for the treatment of uncomplicated severe acute malnutrition.

BACKGROUND: Children treated for severe acute malnutrition (SAM) are at risk of refeeding hypophosphatemia. Therapeutic diets have only recently become fortified with phosphorus to meet United Nations (UN) specifications, but to our knowledge no studies have investigated the effect. OBJECTIVE: The aim was to assess concentrations and correlates of plasma phosphate (P-phosphate) at admission and during treatment and to identify correlates of changes in P-phosphate. DESIGN: This was a prospective observational study in 6- to 59-mo-old children admitted for treatment of SAM to Mulago Hospital, Uganda. P-phosphate was measured at admission, on the second day of treatment with a therapeutic formula containing 75 kcal/100 mL and 560 mg phosphorus/L (F-75, Nutriset), at the start of the transition to a therapeutic formula containing 100 kcal/100 mL and 579 mg phosphorus/L (F-100; Nutriset), at day 2 of transition, and at discharge. RESULTS: Among 120 children, mean ± SD P-phosphate at admission was 1.04 ± 0.31 mmol/L and increased by 0.43 (95% CI: 0.35, 0.52) mmol/L during the first 2 d and more slowly toward discharge. Most (79%) children experienced their lowest P-phosphate concentration at admission, and none developed severe hypophosphatemia. P-phosphate was lowest in children with edema and with elevated C-reactive protein, and a lower increase was seen with increasing caretaker-reported severity of illness. Partially or fully replacing F-75 with rice porridge (i.e., a local practice to reduce diarrhea) during the first 2 d of stabilization was associated with a 0.34-mmol/L (95% CI: 0.18, 0.50 mmol/L) lower increase in P-phosphate during the same first 2 d. CONCLUSIONS: F-75, which complies with UN specifications and provides 73 mg phosphorus · kg(-1) · d(-1) (130 mL · kg(-1) · d(-1)), seems to prevent refeeding hypophosphatemia in children with SAM. Replacing this formula with rice porridge during the first days of treatment to manage diarrhea may have an adverse effect on P-phosphate concentrations.

BACKGROUND & OBJECTIVES: Restoration of body composition indicates successful management of severe acute malnutrition (SAM). Bioimpedance (BI) index (height(2)/resistance) is used to predict total body water (TBW) but its performance in SAM, especially with oedema, requires further investigation. SUBJECTS/METHODS: Children with SAM (mid-arm circumference <11.0 cm or weight-for-height <70% of median of NCHS reference and/or nutritional oedema) admitted to Jimma University Hospital were included. Tetrapolar-whole-body impedance (Z), resistance (R) and reactance (Xc) were measured at 50 and 200 kHzs. Pre- and post-deuterium dose saliva samples were analysed using isotope-ratio mass spectrometry. TBW was regressed on H(2)/Z. Xc and R were height (H)-indexed, and Xc/H plotted against R/H. RESULTS: Thirty five children (16 non-oedematous and 19 oedematous) with median (interquartile range) age of 42 (26-54) months were studied. Height-for-age z-score (mean ± SD) was low in both non-oedematous (-3.9 ± 2.8) and oedematous (-3.6 ± 1.7) children. Oedematous children had lower BI parameters than non-oedematous (p < 0.001) and hence higher H(2)/Z for a given amount of TBW. At both 50 and 200 kHz, association between H(2)/Z and TBW was stronger in non-oedematous children than oedematous (60% higher coefficient of determination and 20% lower standard error of estimate). Intercepts and regression estimates at 50 and 200 kHz were similar, in both oedematous and non-oedematous children. CONCLUSIONS: In children with oedematous SAM, BI index was weak in predicting TBW. Moreover, predicted TBWs at 200 kHz and 50 kHz did not differ and hence BI measurement at 50 kHz is still practical for TBW estimation.
