Risk factors for early occurrence of malnutrition in infants with severe congenital heart disease

To identify the risk factors of early occurrence of malnutrition in infants with severe congenital heart disease (CHD) during their first year of life. Retrospective longitudinal multicenter study carried out from January 2014 to December 2020 in two tertiary care CHD centers. Four CHD hemodynamic groups were identified. Malnutrition was defined by a Waterlow score under 80% and/or underweight under -2 standard deviations. A total of 216 infants with a severe CHD, e.g., requiring cardiac surgery, cardiac catheterization, or hospitalization for heart failure during their first year of life, were included in the study. Malnutrition was observed among 43% of the cohort, with the highest prevalence in infants with increased pulmonary blood flow (71%) compared to the other hemodynamic groups (p < 0.001). In multivariate analysis, low birthweight (OR 0.62, 95% CI 0.44-0.89, p = 0.009), CHD with increased pulmonary blood flow (OR 4.80, 95% CI 1.42-16.20, p = 0.08), heart failure (OR 9.26, 95% CI 4.04-21.25, p < 0.001), and the number of hospitalizations (OR 1.35, 95% CI 1.08 l-1.69, p = 0.009) during the first year of life were associated with malnutrition (AUC 0.85, 95% CI 0.79-0.90).  Conclusions: In infants with a severe CHD, early occurrence of malnutrition during the first year of life affected a high proportion of subjects. CHD with increased pulmonary blood flow, low birthweight, heart failure, and repeated hospitalizations were risk factors for malnutrition. Further studies are required to identify optimal nutritional support in this population. What is Known: • Malnutrition is a known morbidity and mortality factor in children with severe congenital heart disease. What is New: • Early occurrence of malnutrition during the first year of life in infant severe congenital heart disease (CHD) was high (43%). • CHD with increased pulmonary blood flow, low birthweight, heart failure, and repeated hospitalizations during the first year of life were risk factors for malnutrition.

Duodenal Microbiota in Stunted Undernourished Children with Enteropathy

BACKGROUND

Environmental enteric dysfunction (EED) is an enigmatic disorder of the small intestine that is postulated to play a role in childhood undernutrition, a pressing global health problem. Defining the incidence of this disorder, its pathophysiological features, and its contribution to impaired linear and ponderal growth has been hampered by the difficulty in directly sampling the small intestinal mucosa and microbial community (microbiota).

METHODS

In this study, among 110 young children (mean age, 18 months) with linear growth stunting who were living in an urban slum in Dhaka, Bangladesh, and had not benefited from a nutritional intervention, we performed endoscopy in 80 children who had biopsy-confirmed EED and available plasma and duodenal samples. We quantified the levels of 4077 plasma proteins and 2619 proteins in duodenal biopsy samples obtained from these children. The levels of bacterial strains in microbiota recovered from duodenal aspirate from each child were determined with the use of culture-independent methods. In addition, we obtained 21 plasma samples and 27 fecal samples from age-matched healthy children living in the same area. Young germ-free mice that had been fed a Bangladeshi diet were colonized with bacterial strains cultured from the duodenal aspirates.

RESULTS

Of the bacterial strains that were obtained from the children, the absolute levels of a shared group of 14 taxa (which are not typically classified as enteropathogens) were negatively correlated with linear growth (length-for-age z score, r = -0.49; P = 0.003) and positively correlated with duodenal proteins involved in immunoinflammatory responses. The representation of these 14 duodenal taxa in fecal microbiota was significantly different from that in samples obtained from healthy children (P<0.001 by permutational multivariate analysis of variance). Enteropathy of the small intestine developed in gnotobiotic mice that had been colonized with cultured duodenal strains obtained from children with EED.

CONCLUSIONS

These results provide support for a causal relationship between growth stunting and components of the small intestinal microbiota and enteropathy and offer a rationale for developing therapies that target these microbial contributions to EED.

Malaria and Nutritional Status Among Children With Severe Acute Malnutrition in Niger: A Prospective Cohort Study

Background

The relationship between malaria infection and nutritional status is complex. Previous studies suggest malaria may increase the incidence and severity of malnutrition, while malnutrition may increase the risk of malaria infection. Here, we report bidirectional associations between malaria and nutritional status among children with uncomplicated severe acute malnutrition (SAM).

Methods

This study is a secondary analysis of a randomized, controlled trial for the treatment of uncomplicated SAM in Niger. Children aged 6-59 months were enrolled and followed for 12 weeks. Malaria infection was assessed using an histidine-rich protein 2 (HRP2) rapid diagnostic test at admission and at any follow-up visit with fever. We assessed the association of nutritional status at admission on malaria incidence using Cox proportional hazards regression and malaria infection at admission on nutritional recovery and weight and height gain using linear regression.

Results

Of 2399 children included in the analysis, 1327 (55.3%) were infected with malaria at admission. Malaria incidence was 12.1 cases/100 person-months among those without malaria infection at admission. Nutritional status at admission was not associated with malaria incidence. Children with malaria infection at admission and subsequently treated with an artemisinin-based combination therapy had increased weight gain (0.38 g/kg/day; 95% confidence interval [CI], 0.07 to 0.69) and reduced height gain (-0.002 mm/day; 95% CI, -0.004 to -0.0008).

Conclusions

Malaria infection was common among children treated for uncomplicated SAM. Malaria infection may impair height gain. Proper medical and nutritional management should be ensured to prevent adverse effects of malaria infection.

Changes in susceptibility to life-threatening infections after treatment for complicated severe malnutrition in Kenya

Background

Goals of treating childhood severe acute malnutrition (SAM), in addition to anthropometric recovery and preventing short-term mortality, include reducing the risks of subsequent serious infections. How quickly and how much the risk of serious illness changes during rehabilitation are unknown but could inform improving the design and scope of interventions.

Objective

The aim of this study was to investigate changes in the risk of life-threatening events (LTEs) in relation to anthropometric recovery from SAM.

Design

This was a secondary analysis of a clinical trial including 1778 HIV-uninfected Kenyan children aged 2-59 mo with complicated SAM, enrolled after the inpatient stabilization phase of treatment, and followed for 12 mo. The main outcome was LTEs, defined as infections requiring rehospitalization or causing death. We examined anthropometric variables measured at months 1, 3, and 6 after enrollment in relation to LTEs occurring during the 6 mo after each of these time points.

Results

Over 12 mo, there were 823 LTEs (257 fatal), predominantly severe pneumonia and diarrhea. At months 1, 3, and 6, 557 (34%), 764 (49%), and 842 (56%) children had a weight-for-height or -length z score (WHZ) ≥-2, respectively, which, compared with a WHZ <-3, was associated with lower risks of subsequent LTEs [adjusted HRs (95% CIs): 0.50 (0.40, 0.64), 0.30 (0.23, 0.39), and 0.23 (0.16, 0.32), respectively]. However, children with a WHZ ≥-2 at 1, 3, and 6 mo still had 39 (95% CI: 32, 47), 26 (95% CI: 22, 32), and 15 (95% CI: 12, 20) LTEs/100 child-years of observation during the following 6 mo. WHZ at study enrollment predicted subsequent WHZ but not the risk of LTEs. Changes in height-for-age z score did not predict LTEs.

Conclusions

Anthropometric response was associated with a rapid and substantial reduction in risk of LTEs. However, reduction in susceptibility lagged behind anthropometric improvement. Disease events, together with anthropometric assessment, may provide a clearer picture of the effectiveness of interventions. Robust protocols for detecting and treating poor anthropometric recovery and addressing broader vulnerabilities that complicated SAM indicates may save lives. This trial was registered at www.clinicaltrials.gov as NCT00934492.

Characterizing the metabolic phenotype of intestinal villus blunting in Zambian children with severe acute malnutrition and persistent diarrhea

Background

Environmental enteric dysfunction (EED) is widespread throughout the tropics and in children is associated with stunting and other adverse health outcomes. One of the hallmarks of EED is villus damage. In children with severe acute malnutrition (SAM) the severity of enteropathy is greater and short term mortality is high, but the metabolic consequences of enteropathy are unknown. Here, we characterize the urinary metabolic alterations associated with villus health, classic enteropathy biomarkers and anthropometric measurements in severely malnourished children in Zambia.

Methods/Principal findings

We analysed 20 hospitalised children with acute malnutrition aged 6 to 23 months in Zambia. Small intestinal biopsies were assessed histologically (n = 15), anthropometric and gut function measurements were collected and the metabolic phenotypes were characterized by ¹H nuclear magnetic resonance (NMR) spectroscopy.

Endoscopy could not be performed on community controls children. Growth parameters were inversely correlated with enteropathy biomarkers (p = 0.011) and parameters of villus health were inversely correlated with translocation and permeability biomarkers (p = 0.000 and p = 0.015). Shorter villus height was associated with reduced abundance of metabolites related to gut microbial metabolism, energy and muscle metabolism (p = 0.034). Villus blunting was also related to increased sucrose excretion (p = 0.013).

Conclusions/Significance

Intestinal villus blunting is associated with several metabolic perturbations in hospitalized children with severe undernutrition. Such alterations include altered muscle metabolism, reinforcing the link between EED and growth faltering, and a disruption in the biochemical exchange between the gut microbiota and host. These findings extend our understanding on the downstream consequences of villus blunting and provide novel non-invasive biomarkers of enteropathy dysfunction. The major limitations of this study are the lack of comparative control group and gut microbiota characterization.

Analytical considerations and general diagnostic and therapeutic ramifications of milk hormones during lactation

In this review, we will discuss the changes that occur in the mammary gland from pregnancy to lactation and the issues surrounding the analysis of circulating and milk hormones during the stages of lactogenesis. There is a cascade of events that must occur to achieve milk synthesis, milk ejection, and successful transfer to the breastfeeding infant. The adequacy and success of this process is no small measure and the assessment of milk production, the hormones involved in this process and the ability to properly diagnose conditions and causes of low milk supply are critical for the health and well-being of the mother-infant breastfeeding dyad. The normative data that have been amassed in past decades suggest that there are certain values or circulating concentrations of milk hormones, that if lacking or low, could explain low milk supply status. Yet, in looking more closely at the tests themselves, the certainly of what constitutes "normal" can vary depending on the preanalytical conditions that the blood or milk sample were obtained, the methods used in obtaining circulating or milk concentrations, and the standardization of how that result is expressed. The standardization of these aspects of breast milk physiology are essential for providing important normative data to health care professionals and researchers and will result in more consistent findings across multi-disciplinary platforms.

Nutrition in extremely low birth weight infants: impact on bronchopulmonary dysplasia

BACKGROUND

Bronchopulmonary dysplasia (BPD) is a chronic lung disease that affects premature infants with multifactorial etiology. Some authors have considered malnutrition to be a major factor promoting BDP. The aim of our study was to examine the contribution of enteral and parenteral nutritional intake in the first 14 days of life to the development of bronchopulmonary dysplasia in a sample of preterm infants.

METHODS

A prospective cohort study was conducted on all preterm infants born between 1 January 2008 and 31 December 2013. The nutritional parameters compiled included the cumulative amount of fluids, calories, proteins, carbohydrates and lipids consumed. Statistical analysis of the data consisted of a descriptive analysis, Mann-Whitney pairwise comparison test and logistic regression.

RESULTS

The total caloric intake in the infants studied was significantly lower in patients with subsequent bronchopulmonary dysplasia (76.1 kCal/kg, 95% CI: 71.2-81.1 vs. 91.1 kCal/kg, 95% CI: 87.5-94.8). The intake of carbohydrate and fat was significantly lower in the patients with BPD (11.6 g/kg, 95% CI: 11.1-12.0 vs. 12.6 g/kg, 95% CI: 12.1-13; and 2.5 g/kg, 95% CI: 2.3-2.7 vs. 3.4 g/kg, 95% CI: 2.9-3.9, respectively).

CONCLUSIONS

Our study shows that infants who develop bronchopulmonary dysplasia receive a lower enteral intake of calories and total lipids during the first 14 days of life.

Natural History of Cryptosporidiosis in a Longitudinal Study of Slum-Dwelling Bangladeshi Children: Association with Severe Malnutrition

Background

Cryptosporidiosis is a common cause of infectious diarrhea in young children worldwide, and is a significant contributor to under-five mortality. Current treatment options are limited in young children. In this study, we describe the natural history of Cryptosporidium spp. infection in a birth cohort of children in Bangladesh and evaluate for association with malnutrition.

Methodology/Principal Findings

This is a longitudinal birth cohort study of 392 slum-dwelling Bangladeshi children followed over the first two years of life from 2008 to 2014. Children were monitored for diarrheal disease, and stool was tested for intestinal protozoa. Anthropometric measurements were taken at 3-month intervals. A subset of Cryptosporidium positive stools were genotyped for species and revealed that C. hominis was isolated from over 90% of samples. In the first two years of life, 77% of children experienced at least one infection with Cryptosporidium spp. Non-diarrheal infection (67%) was more common than diarrheal infection (6.3%) although 27% of children had both types of infection. Extreme poverty was associated with higher rates of infection (chi-square, 49.7% vs 33.3%, p = 0.006). Malnutrition was common in this cohort, 56% of children had stunted growth by age two. Children with Cryptosporidium spp. infection had a greater than 2-fold increased risk of severe stunting at age two compared to uninfected children (odds ratio 2.69, 95% CI 1.17, 6.15, p = 0.019) independent of sex, income, maternal body-mass index, maternal education and weight for age adjusted z (WAZ) score at birth.

Conclusions/Significance

Cryptosporidium infection is common (77%) in this cohort of slum-dwelling Bangladeshi children, and both non-diarrheal and diarrheal infections are significantly associated with a child’s growth at 2 years of age.

Diarrheal disease is a leading cause of death in young children worldwide. Cryptosporidium species are responsible for a large proportion of global burden of diarrhea. This study describes the natural history of cryptosporidiosis in a birth cohort of impoverished Bangladeshi children. Children were enrolled at birth and monitored for diarrhea twice a week for two years. Stool samples were tested for enteric protozoa. Children in this cohort had significant rates of malnutrition compared to the W.H.O. reference population, and extreme poverty was common. A majority of children were infected with Cryptosporidium spp, and we found that children who had at least one infection with Cryptosporidium spp during the two year follow up period were significantly more likely to have growth faltering by age 24 months. Cryptosporidiosis is a common infection in this cohort, and is associated with poverty and reduced growth during the first two years of life.

Audiometric thresholds and auditory processing in children with early malnutrition: a retrospective cohort study

CONTEXT AND OBJECTIVE

Malnutrition is one of the causes of changes in cell metabolism. The inner ear has few energy reserves and high metabolism. The aim of this study was to analyze whether malnutrition at an early age is related to impairment of auditory processing abilities and hearing abnormalities.

DESIGN AND SETTING

Retrospective cohort study conducted in a tertiary public hospital.

METHODS

45 children participated, divided as follows: G1, children diagnosed with malnutrition in their first two years of life; G2, children without history of malnutrition but with learning difficulties; G3, children without history of malnutrition and without learning difficulties. Tympanometry, pure-tone audiometry and the Staggered Spondaic Word (SSW) test (auditory processing) were performed. Statistical inferences were made using the Kruskal-Wallis test (α = 5%) and the test of equality of proportions between two samples (α = 1.7%).

RESULTS

None of the 45 children participating in this study presented hearing deficiencies. However, at six of the eight frequencies analyzed, the children in G1 presented hearing thresholds lower than those of the other groups. In the auditory processing evaluation test, it was observed that 100% of the children in G1 presented abnormal auditory processing and that G1 and G2 had similar proportions of abnormalities (P-values: G1/G2 = 0.1; G1/G3 > 0.001; G2/G3 = 0.008).

CONCLUSIONS

Malnutrition at an early age caused lowering of the hearing levels, although this impairment could not be considered to be a hearing deficiency. Every child in this group presented abnormalities in auditory processing abilities.

Chediak-Higashi syndrome in accelerated phase masquerading as severe acute malnutrition

A toddler presented with poor appetite, weight loss and frequent respiratory tract infections for the past 6 months, fever and increasing paleness for the past 2 months and bilateral pedal oedema for the past 1 month. Anthropometry confirmed severe acute malnutrition. Clinical and laboratory evaluation revealed that the child also had hypopigmented hair and skin, splenohepatomegaly, pancytopenia and hypoalbuminaemia. The coexistence of hypopigmentation and suspected low immunity prompted us to investigate the child's hair, peripheral blood smear and bone marrow. Hair under light microscopy showed evenly distributed, large melanin granules, suggestive of Chediak-Higashi syndrome (CHS). Peripheral blood smear and bone marrow aspirate examinations revealed abnormal large intracytoplasmic granules, which was diagnostic of CHS. The child's investigations revealed coexistent hemophagocytic lymphohistiocytosis, confirming the diagnosis of CHS in 'accelerated phase', which is fatal if not treated. The parents prematurely took the child home against medical advice, before definitive therapy could be instituted.

[Gut feeling in youth health care: 2 cases]

BACKGROUND

Dutch Youth health care is an easily accessible service where parents can ask for support for the healthy development of their children. The majority of the screenings and medical examinations show no abnormalities. Sometimes there is doubt about the severity of symptoms: the line between healthy variation and diseases or abnormalities can be rather fine.

CASE DESCRIPTION

Patient A, a 3-month-old baby, showed signals of hypotonia and growth deficit while breastfeeding. Additional nutrition restored his growth and muscle tone. Patient B, a 4-week-old baby, displayed severe hypotonia. This appeared to be based on Werdnig-Hoffman disease. He died at the age of 4 months.

CONCLUSION

Distinguishing conditions in the normal range from rare and severe conditions is daily work for every physician and is based on knowledge and experience. Combining symptoms and signs is essential. The youth health care physician sees mostly healthy children and is aware of the great variation within that group. This makes the youth health care physician an expert in distinguishing conditions in the normal range from rare and severe conditions.

Recurrent sclerema in a young infant presenting with severe sepsis and severe pneumonia: an uncommon but extremely life-threatening condition

A one month and twenty-five days old baby girl with problems of acute watery diarrhoea, severe dehydration, severe malnutrition, and reduced activity was admitted to the gastrointestinal unit of Dhaka Hospital of icddr,b. The differentials included dehydration, dyselectrolytaemia and severe sepsis. She was treated following the protocolized management guidelines of the hospital. However, within the next 24 hours, the patient deteriorated with additional problems of severe sepsis, severe pneumonia, hypoxaemia, ileus, and sclerema. She was transferred to the Intensive Care Unit (ICU). In the ICU, she was managed with oxygen supplementation, intravenous antibiotics, intravenous fluid, including a number of blood transfusions, vitamins, minerals, and diet. One month prior to this admission, she had been admitted to the ICU also with sclerema, septic shock, and urinary tract infection due to Escherichia coli and was discharged after full recovery. On both the occasions, she required repeated blood transfusions and aggressive antibiotic therapy in addition to appropriate fluid therapy and oxygen supplementation. She fully recovered from severe sepsis, severe malnutrition, ileus, sclerema, and pneumonia, both clinically and radiologically and was discharged two weeks after admission. Consecutive episodes of sclerema, resulting in two successive hospitalizations in a severely-malnourished young septic infant, have never been reported. However, this was managed successfully with blood transfusion, broad-spectrum antibiotics, and correction of electrolyte imbalance.

Effects of neonatal programming on hypothalamic mechanisms controlling energy balance

The prevalence of overweight and obesity in most developed countries has markedly increased during the last decades. In addition to genetic, hormonal, and metabolic influences, environmental factors like fetal and neonatal nutrition play key roles in the development of obesity. Interestingly, overweight during critical developmental periods of fetal and/or neonatal life has been demonstrated to increase the risk of obesity throughout juvenile life into adulthood. In spite of this evidence, the specific mechanisms underlying this fetal/neonatal programming are not perfectly understood. However, it is clear that circulating hormones such as insulin and leptin play a critical role in the development and programming of hypothalamic circuits regulating energy balance. Here, we review what is currently known about the impact of perinatal malnutrition on the mechanisms regulating body weight homeostasis. Understanding these molecular mechanisms may provide new targets for the treatment of obesity.

Impaired IQ and academic skills in adults who experienced moderate to severe infantile malnutrition: a 40-year study

OBJECTIVES

To evaluate IQ and academic skills in adults who experienced an episode of moderate-to-severe infantile malnutrition and a healthy control group, all followed since childhood in the Barbados Nutrition Study.

METHODS

IQ and academic skills were assessed in 77 previously malnourished adults (mean age = 38.4 years; 53% male) and 59 controls (mean age = 38.1 years; 54% male). Group comparisons were carried out by multiple regression and logistic regression, adjusted for childhood socioeconomic factors.

RESULTS

The previously malnourished group showed substantial deficits on all outcomes relative to healthy controls (P < 0.0001). IQ scores in the intellectual disability range (< 70) were nine times more prevalent in the previously malnourished group (odds ratio = 9.18; 95% confidence interval = 3.50-24.13). Group differences in IQ of approximately one standard deviation were stable from adolescence through mid-life.

DISCUSSION

Moderate-to-severe malnutrition during infancy is associated with a significantly elevated incidence of impaired IQ in adulthood, even when physical growth is completely rehabilitated. An episode of malnutrition during the first year of life carries risk for significant lifelong functional morbidity.

NUTRITIONAL STATUS OF CHILDREN ADMITTED FOR DIARRHOEAL DISEASES IN A REFERRAL HOSPITAL IN WESTERN KENYA

OBJECTIVES

To determine the prevalence of malnutrition among children admitted with acute diarrhoea disease at Moi Teaching and Referral Hospital and to establish the effect of malnutrition on duration of hospital stay.

DESIGN

Prospective observational study.

SETTING

Paediatric wards of Moi Teaching and Referral Hospital, Eldoret, Kenya.

SUBJECTS

A total of 191 children aged 6 and 59 months admitted with acute diarrhoea disease, without chronic co-morbidities or visible severe malnutrition, were systematically enrolled into the study between November 2011 and March 2012.

OUTCOME MEASURES

Nutritional status based on WHO WHZ scores taken at admission and duration of hospital stay.

RESULTS

The mean age was 13.2 months with a male to female sex ratio of 1.16:1. Of all the children seen with acute diarrhoeal diseases, 43.9% had acute malnutrition (<-2 WHZ score), with 12% being severely malnourished (<-3 Z score). Average duration of hospital stay was 3.36 (SD=1.54) days. Among those with malnutrition the average duration of stay was 3.39 (SD=1.48) days while for those without malnutrition it was 3.21(SD=1.20) days, which was not statistically different. No death was reported. WHO weight for Height Z scores picked 12% of severe form of malnutrition missed out by Welcome Trust classification (weight for age).

CONCLUSION

Routine anthrometry including weight for height identifies more children with malnutrition in acute diarrhoeal diseases. Presence of malnutrition did not affect duration of hospital stay.

Early postnatal life as a critical time window for determination of long-term metabolic health

Epidemiological studies demonstrated a clear phenomenological association between low birth weight and increased cardiometabolic risk later in life, very similar to that in high birth weight subjects. Pre- and/or neonatal overfeeding appears to be an etiological clue. In animal studies, irrespective of birth weight neonatal over-nutrition leads to later overweight, impaired glucose tolerance and cardiometabolic alterations. Probably, perinatally acquired alterations of DNA methylation patterns of gene promoters of central nervous regulators of body weight and metabolism play a key role in mediating these relationships. In humans, the long-term impact of neonatal nutrition is conclusively demonstrated by studies on the consequences of breastfeeding vs. formula-feeding. Taken together, the quantity and quality of nutrition during neonatal life plays a critical role, beyond prenatal development, in the long-term programming of health and disease. This opens a variety of opportunities and challenges to primarily prevent chronic diseases, e.g. the metabolic syndrome.

Dietary cysteine is used more efficiently by children with severe acute malnutrition with edema compared with those without edema

BACKGROUND

Children with edematous severe acute malnutrition (SAM) produce less cysteine than do their nonedematous counterparts. They also have marked glutathione (GSH) depletion, hair loss, skin erosion, gut mucosal atrophy, and depletion of mucins. Because GSH, skin, hair, mucosal, and mucin proteins are rich in cysteine, we hypothesized that splanchnic extraction and the efficiency of cysteine utilization would be greater in edematous than in nonedematous SAM.

OBJECTIVE

We aimed to measure cysteine kinetics in childhood edematous and nonedematous SAM.

DESIGN

Cysteine flux, oxidation, balance, and splanchnic uptake (SPU) were measured in 2 groups of children with edematous (n = 9) and nonedematous (n = 10) SAM at 4.4 ± 1.1 d after admission (stage 1) and at 20.5 ± 1.6 d after admission (stage 2) when they had replenished 50% of their weight deficit.

RESULTS

In comparison with the nonedematous group, the edematous group had slower cysteine flux at stage 1 but not at stage 2; furthermore, they oxidized less cysteine at both stages, resulting in better cysteine balance and therefore better efficiency of utilization of dietary cysteine. Cysteine SPU was not different between groups but was ∼45% in both groups at the 2 stages.

CONCLUSION

These findings suggest that children with edematous SAM may have a greater requirement for cysteine during early and mid-nutritional rehabilitation because they used dietary cysteine more efficiently than did their nonedematous counterparts and because the splanchnic tissues of all children with SAM have a relatively high requirement for cysteine. This trial was registered at clinicaltrials.gov as NCT00069134.

Community based nutritional rehabilitation of severely malnourished children

OBJECTIVE

To improve nutrition of malnourished children in the community, using home based treatment.

METHODS

A prospective cohort study was conducted in a squatter settlement of Karachi (Khuda Ki Basti). The study was conducted from August 2006 to March 2007. All children <5 years who were <-3sd weight for height were included as per WHO guidelines. After initial screening for complications, the children were provided with high density diet (HDD). Daily weight, amount of HDD consumed and complications were recorded.

RESULTS

A total of 24 children were included in the study. Eleven children (45.8%) reached - 1SD at the end of 3 months while 10 patients (41.6%) took 4 months. Twenty two patients (91.6%) were at the median weight for height by the end of 5 months.

CONCLUSION

Home based treatment with locally available foods can be used successfully to rehabilitate severely malnourished children.
