RESUMO

OBJECTIVE: This systematic review commissioned by WHO aimed to synthesise evidence from current literature on the effects of systematically given, routine use of antibiotics for infants under 6 months of age with growth failure/faltering. SETTINGS: Low-income and middle-income countries. PARTICIPANTS: The study population was infants less than 6 months of age with growth failure/faltering. INTERVENTION: The intervention group was infants who received no antibiotics or antibiotics other than those recommended in 2013 guidelines by WHO to treat childhood severe acute malnutrition. The comparison group was infants who received antibiotics according to the aforementioned guidelines. PRIMARY AND SECONDARY OUTCOMES: The primary outcome was all-cause mortality, and secondary outcomes: clinical deterioration, antimicrobial resistance, recovery from comorbidity, adverse events, markers of intestinal inflammation, markers of systemic inflammation, hospital-acquired infections and non-response. The Grading of Recommendations Assessment, Development and Evaluation approach was considered to report the overall evidence quality for an outcome. RESULTS: We screened 5137 titles and abstracts and reviewed the full text of 157 studies. None of the studies from the literature search qualified to answer the question for this systematic review. CONCLUSIONS: There is a paucity of evidence on the routine use of antibiotics for the treatment of malnutrition in infants less than 6 months of age. Future studies with adequate sample sizes are needed to assess the potential risks and benefits of antibiotics in malnourished infants under 6 months of age.

RESUMO

INTRODUCTION: Environmental enteric dysfunction (EED) predisposes children throughout the developing world to high rates of systemic exposure to enteric pathogens and stunting. Effective interventions that treat or prevent EED may help children achieve their full physical and cognitive potential. The objective of this study is to test whether 2 components of breast milk would improve a biomarker of EED and linear growth during the second year of life. METHODS: A prospective, randomized, double-blind, placebo-controlled clinical trial among children aged 12-23 months was conducted in rural Malawi. The experimental group received a daily supplement of 1.5 g of lactoferrin and 0.2 g of lysozyme for 16 weeks. The primary outcome was an improvement in EED, as measured by the change in the percentage of ingested lactulose excreted into the urine (Δ%L). RESULTS: Among 214 children who completed the study, there was a significant difference in Δ%L between the control and experimental groups over 8 weeks (an increase of 0.23% vs 0.14%, respectively; P = 0.04). However, this relative improvement was not as strongly sustained over the full 16 weeks of the study (an increase of 0.16% vs 0.11%, respectively; P = 0.17). No difference in linear growth over this short period was observed. The experimental intervention group had significantly lower rates of hospitalization and the development of acute malnutrition during the course of the study (2.5% vs 10.3%, relative risk 0.25; P < 0.02). DISCUSSION: Supplementation with lactoferrin and lysozyme in a population of agrarian children during the second year of life has a beneficial effect on gut health. This intervention also protected against hospitalization and the development of acute malnutrition, a finding with a significant clinical and public health importance. This finding should be pursued in larger studies with longer follow-up and optimized dosing.

RESUMO

Background: Vitamin D deficiency is common in children with severe acute malnutrition, in whom it is associated with severe wasting. Ready-to-use therapeutic food (the standard treatment) contains modest amounts of vitamin D that do not reliably correct deficiency. Objective: The aim of this study was to determine whether high-dose oral vitamin D3 enhances weight gain and development in children with uncomplicated severe acute malnutrition. Design: We conducted a randomized placebo-controlled trial of high-dose vitamin D3 supplementation in children aged 6-58 mo with uncomplicated severe acute malnutrition in Pakistan. Participants were randomly assigned to receive 2 oral doses of 200,000 IU vitamin D3 or placebo at 2 and 4 wk after starting ready-to-use therapeutic food. The primary outcome was the proportion of participants gaining >15% of baseline weight at 8 wk after starting ready-to-use therapeutic food (the end of the study). Secondary outcomes were mean weight-for-height or -length z score and the proportion of participants with delayed development at the end of the study (assessed with the Denver Development Screening Tool II), adjusted for baseline values. Results: Of the 194 randomly assigned children who started the study, 185 completed the follow-up and were included in the analysis (93 assigned to intervention, 92 to control). High-dose vitamin D3 did not influence the proportion of children gaining >15% of baseline weight at the end of the study (RR: 1.04; 95% CI: 0.94,1.15, P = 0.47), but it did increase the weight-for-height or -length z score (adjusted mean difference: 1.07; 95% CI: 0.49,1.65, P < 0.001) and reduce the proportion of participants with delayed global development [adjusted RR (aRR): 0.49; 95% CI: 0.31, 0.77, P = 0.002], delayed gross motor development (aRR: 0.29; 95% CI: 0.13, 0.64, P = 0.002), delayed fine motor development (aRR: 0.59; 95% CI: 0.38, 0.91, P = 0.018), and delayed language development (aRR: 0.57; 95% CI: 0.34, 0.96, P = 0.036). Conclusions: High-dose vitamin D3 improved the mean weight-for-height or -length z score and developmental indexes in children receiving standard therapy for uncomplicated severe acute malnutrition in Pakistan. This trial was registered at clinicaltrials.gov as NCT03170479.

RESUMO

BACKGROUND: Chronic childhood malnutrition, as manifested by stunted linear growth, remains a persistent barrier to optimal child growth and societal development. Environmental enteric dysfunction (EED) is a significant underlying factor in the causal pathway to stunting, delayed cognitive development, and ultimately morbidity and mortality. Effective therapies against EED and stunting are lacking and further clinical trials are warranted to effectively identify and operationalize interventions. METHODS/DESIGN: A prospective randomized placebo-controlled parallel-group randomized controlled trial will be conducted to determine if a daily supplement of lactoferrin and lysozyme, two important proteins found in breast milk, can decrease the burden of EED and stunting in rural Malawian children aged 12-23 months old. The intervention and control groups will have a sample size of 86 subjects each. All field and laboratory researchers will be blinded to the assigned intervention group, as will the subjects and their caregivers. The percentage of ingested lactulose excreted in the urine (Δ%L) after 4 h will be used as the biomarker for EED and linear growth as the measure of chronic malnutrition (stunting). The primary outcomes of interest will be change in Δ%L from baseline to 8 weeks and to 16 weeks. Intention-to-treat analyses will be used. DISCUSSION: A rigorous clinical trial design will be used to assess the biologically plausible use of lactoferrin and lysozyme as dietary supplements for children at high risk for EED. If proven effective, these safe proteins may serve to markedly reduce the burden of childhood malnutrition and improve survival. TRIAL REGISTRATION: Clinicaltrials.gov, NCT02925026 .

RESUMO

OBJECTIVE: Circulatory failure due to acute arterial hypertension in the neonatal period is rare. This study was undertaken to assess the clinical and echocardiographic manifestations of circulatory failure resulting from acute neonatal hypertensive crisis. METHODS: Neonatal and cardiology databases from 2007 to 2010 were reviewed. An established diagnosis of circulatory failure due to neonatal hypertension before the age of 14 days was required for inclusion. Six patients were identified. RESULTS: Five patients presented with circulatory failure due to an acute hypertensive crisis. The median age at presentation was 8.5 days (range: 6.0-11.0) with a median body weight of 3.58 kg (range: 0.86-4.70). Echocardiography demonstrated mild left ventricular dysfunction [median shortening fraction (SF) 25%, range 10-30] and mild aortic regurgitation in 83% (5/6) of patients. One patient with left ventricular dysfunction (SF = 17%) had a large apical thrombus. Two patients were hypotensive, and hypertension only became evident after restoration of cardiac output. Administration of intravenous milrinone was successful, with rapid improvement of the clinical condition. Left ventricular function normalised in all survivors. CONCLUSION: Early neonatal circulatory collapse due to arterial hypertension is a rare but potentially life-threatening condition. At presentation, hypotension, especially in the presence of a dysfunctional left ventricle, does not exclude a hypertensive crisis being the cause of circulatory failure. The echocardiographic presence of mild aortic regurgitation combined with left ventricular hypocontractility in a structurally normal heart should alert the physician to the presence of underlying hypertension.

RESUMO

A 17-month-old girl presented with an upper respiratory tract infections, and was found to have a haemoglobin of 3.3 g/dl. Although noticeably pale, she was largely asymptomatic. Her iron deficiency anaemia was found to be the result of poor diet. With oral iron supplements and improved diet, her haemoglobin increased rapidly, and she is now doing very well.

RESUMO

BACKGROUND/OBJECTIVES: Physical activity and exploration in infancy affect physical and cognitive development. Nutritional supplementation improves activity in severely malnourished infants, but the evidence in mild-to-moderately malnourished and nutritionally at-risk infants is equivocal. We tested the effect of multiple-micronutrient supplementation on physical activity and exploration in Mexican infants. SUBJECTS/METHODS: Using a quasi experimental design, we analyzed data from a supplementation study that lacked a placebo-control group. We compared infants between 8 and 12 months measured at baseline who had received no supplementation (comparison group, n=78), with infants 8-12 months measured after 4 months of daily supplementation (treatment group, n=109). The treatment consisted of three supplement types: micronutrient powder, syrup (each containing only micronutrients) and a milk-based, fortified-food supplement (FFS; containing micronutrients and macronutrients). We formed the micronutrient-only group (MM) by combining the micronutrient powder and syrup groups. We measured activity and exploration by direct observation and used cluster analysis to form and characterize activity and exploration clusters. We performed logistic regression with activity or exploration cluster as the outcome variable and treatment versus comparison and MM or FFS versus comparison as the predictor variables. RESULTS: Treatment versus comparison increased the odds of being in the high activity (odds ratio (OR)=2.35, P<0.05) and high exploration (OR=1.87, P<0.05) cluster. MM increased the odds of being in the high activity (OR=2.64, P<0.05) cluster and FFS increased the odds (OR=3.16, P<0.05) of being in the high exploration cluster. CONCLUSIONS: Nutritional supplementation benefited activity and exploration in this sample of Mexican infants.

RESUMO

Iron deficiency in infancy negatively impacts a variety of neurodevelopmental processes at the time of nutrient insufficiency, with persistent central nervous system alterations and deficits in behavioral functioning, despite iron therapy. In rodent models, early iron deficiency impairs the hippocampus and the dopamine system. We examined the possibility that young adults who had experienced chronic, severe, iron deficiency as infants would exhibit deficits on neurocognitive tests with documented frontostriatal (Trail Making Test, Intra-/Extra-dimensional Shift, Stockings of Cambridge, Spatial Working Memory, Rapid Visual Information Processing) and hippocampal specificity (Pattern Recognition Memory, Spatial Recognition Memory). Participants with chronic, severe iron deficiency in infancy performed less well on frontostriatal-mediated executive functions, including inhibitory control, set-shifting, and planning. Participants also exhibited impairment on a hippocampus-based recognition memory task. We suggest that these deficits may result from the long-term effects of early iron deficiency on the dopamine system, the hippocampus, and their interaction.

RESUMO

OBJECTIVE: To determine the differential efficacy and safety of twice-weekly administration of 3 RDAs of iron and folic acid, with and without a complement of 2 RDAs of 11, and 1 RDA of 3 additional essential micronutrients as compared to a placebo control (PlbCON) given as foodLETs. SUBJECTS/METHODS: A total of 250 children aged 6-24 months were enrolled after recruitment by village health workers; 19 of them dropped out during the trial. Children were assigned to one of three treatment arms and followed for 20.5 weeks; 41 supervised twice-weekly dosings of 30 mg of iron plus folic acid, either with or without accompanying micronutrients or placebo were given as foodLETs, a tool for ready-to-eat fortification in infant food. Initial and final measurements of anthropometry and blood biomarkers for hematological, iron stores and inflammatory status, as well as for abnormal hemoglobin (Hb), were obtained. Symptoms of listlessness, vomiting, watery stools and acute respiratory infections were monitored weekly. RESULTS: Iron-containing supplements increased Hb concentrations significantly (P<0.0001) and virtually eradicated any IDA, as compared to no change in hematological status in the PlbCON group (P=0.011). Iron stores, as reflected by ferritin, increased significantly with iron-containing treatments (P<0.0001). Responses were as effective in individuals with HbE as in those with exclusively HbA phenotypes. Watery stools (P=0.002) and listlessness (P=0.001) were significantly more frequent in those receiving iron and folic acid alone than in the PlbCON group. In contrast, acute respiratory infections (P=0.014) and listlessness (P=0.001) were significantly less frequent in those receiving the multiple micronutrient formulation than in the PlbCON group. CONCLUSIONS: Supplementation of micronutrients along with iron and folic acid mitigates the excess morbidity of iron-folate alone, without reducing its efficacy in correcting anemia and building iron stores. FoodLETs are a suitable vehicle to provide micronutrient supplementation to infants.

RESUMO

Neonatal diabetes mellitus is rare, may either be transient or permanent, and may be caused by mutations in any of the several different genes. Until recently, most forms of permanent neonatal diabetes required lifelong subcutaneous insulin for management; however, permanent neonatal diabetes due to activating mutations in the KCNJ11 gene, which encodes the Kir6.2 protein subunit of the ATP-sensitive K+ (K(ATP)) channel, may be amenable to oral sulfonylurea therapy. We describe a case of an 18-month-old infant with permanent neonatal diabetes due to an activating KCNJ11 mutation successfully transitioned from subcutaneous insulin therapy to oral sulfonylurea therapy in the outpatient setting.

RESUMO

Zinc supplementation has been shown to benefit linear growth. However the effect may depend on whether zinc is the most limiting nutrient. This study aims to investigate the effect of supplementation with zinc-given alone or with iron and vitamin-A in improving infantsf micronutrient status and linear growth. The study was a double-blind-community-intervention study involving 800 infants aged 3-6 months in rural East Lombok, West Nusa Tenggara. Syrup consisting of zinc-alone, Zn (10 mg/d), zinc+iron, Zn+Fe (10 mg/d of each), zinc+iron+vitamin-A, Zn+Fe+vit.A (10 mg/d of each zinc and iron plus 1,000 IU vitamin-A), or placebo were given daily for six months. Outcomes measured were length, weight, and micronutrient status (haemoglobin, se-rum zinc, ferritin and retinol). Zn+Fe and Zn+Fe+vit.A supplementations benefit zinc and iron status of the sub-jects, while Zn-alone supplementation disadvantaged haemoglobin and iron status. The highest increment in vi-tamin A and haemoglobin status was shown in Zn+Fe+vit.A group. An effect on linear growth was observed among initially-stunted subjects in Zn+Fe and Zn+Fe+vit.A groups who grew 1.1-1.5 cm longer than placebo. On the other hand, in the Zn-alone group, mean height-for-age Z-score decreased to a greater extent than placebo. The between-group difference in HAZ among initially-stunted subjects was significant after four months sup-plementation. While the difference was not significant in follow-up after 6 months, the pattern remained the same where means height-for-age Z-score in Zn+Fe+vit.A and Zn+Fe groups were higher than placebo and Zn-alone groups. Given the low haemoglobin/iron status of the subjects, zinc supplementation would have positive effect on growth if the low haemoglobin/iron status is also addressed and corrected.

RESUMO

BACKGROUND: Infants aged 6-24 mo are at high risk of iron deficiency. Numerous studies worldwide have sought to identify predictors of iron deficiency in this age group. OBJECTIVE: The objectives of the study were to apply a physiologic model to identify risk factors for iron deficiency and to consider those risk factors under different conditions of iron supplementation. We predicted that factors related to iron status at birth (lower gestational age and lower birth weight), postnatal needs for iron (more rapid growth), and bioavailable iron (more cow milk) would be major risk factors. DESIGN: The physiologic framework was assessed in 1657 Chilean infants (aged 12 mo) with birth weights >or=3 kg who were randomly assigned at age 6 mo to high or low iron supplementation or no added iron. Based on venous blood, the analysis used mean corpuscular volume and concentrations of hemoglobin, free erythrocyte protoporphyrin, and ferritin. Logistic regression models were used to identify predictors of iron deficiency anemia and iron deficiency without anemia. RESULTS: The prevalence of iron deficiency (>or=2 abnormal iron measures) was 34.9% at age 12 mo. Of 186 infants with hemoglobin concentrations <110 g/L, 158 (84.9%) were iron deficient. The only consistent (and the strongest) predictor of iron deficiency or iron deficiency anemia was lower 6-mo hemoglobin. Factors related to poorer iron status at birth (lower birth weight, shorter gestation though full-term, or both) were predictors in the no-added-iron and high-iron groups. Otherwise, predictors varied by iron supplementation. CONCLUSION: Variations in predictors of iron deficiency or iron deficiency anemia according to iron supplementation suggest that direct comparisons across studies are tenuous at best without data on early iron status and certainty that specific conditions are comparable.

RESUMO

Vitamin D deficiency rickets occasionally resembles pseudohypoparathyroidism type II (PHP type II) with respect to the response to exogenous PTH in the presence of hypocalcemia. We encountered a Japanese patient with stage 2 vitamin D deficiency rickets, who had increased urinary cAMP excretion and no response of urinary phosphate or N-acetyl-beta-D-glucosaminidase excretion to exogenous PTH under normocalcemic and normophosphatemic conditions, after treatment with 1,25(OH)2 vitamin D3. This case shows that it is possible for a response mimicking that of PHP type II to occur when the serum calcidiol level is low due to causes other than hypocalcemia and secondary hyperparathyroidism. When the serum calcidiol level is low, the appropriate treatment should be cholecalciferol or ergocalciferol. However, because neither is commercially available as a useful formulation in Japan, physicians are forced to inappropriately use calcitriol or analogs.

RESUMO

This case control study was conducted to determine the frequency of nutritional rickets among hospitalized infants and to assess their relation to respiratory diseases. All infants between the age of 3 months and 2 years admitted to the pediatric ward of Queen Alia Military Hospital during the period February-October 2001 were examined and investigated to rule out nutritional rickets. Children admitted for the first time to hospital for acute illnesses were only included in the study. A special data collection sheet was designed for this study which includes information on the age, sex, causes of admission, family size, the rank of the child in the family, family monthly income, outdoor clothing habit of the mother, and the mode of feeding. Data were collected from the infant charts and/or by interviewing the child's mother or guardian. Clinical signs of rickets were also recorded, including rosary beads, craniotabes, wide anterior fontanel, delayed dentition, widening of epiphysis, bowing of the legs, and double malulous. Blood sample was collected for calcium, phosphorus, alkaline phosphatase, and hemoglobin level. Those infants with any clinical sign of rickets and/or abnormal chemical results had a wrist X-ray to confirm the diagnosis of rickets. The rachitic group (cases) was compared for statistical significance with the remaining non-rachitic infants (controls) for the data collected. Rachitic infants received intramuscular 600,000 IU of vitamin D; a follow-up wrist X-ray and blood sample for calcium, phosphorus and alkaline phosphatase was arranged 3 weeks later. Forty-seven infants (10.6 per cent) out of the 443 included in the study were found to have nutritional rickets. Forty (85.1 per cent) of the rachitic infants were admitted due to lower respiratory tract diseases compared with 30 per cent of the control group and the difference was statistically significant (p < 0.01). Duration of hospital stay in the rachitic infants was also significantly more prolonged than the non-rachitic control group (9.5 days vs. 7.4 days, p = 0.002). Rachitic infants were breastfed in 82.9 per cent, ranked second or more in the family in 87.2 per cent, and had mothers who wore head cover outdoors in 80.8 per cent compared with 60.8, 40.1, and 60.3 per cent, respectively, in the non-rachitic group (p < 0.01). High alkaline phosphatase, hypocalcemia, hypophosphatemia, and anemia was found in 100, 19, 50, and 78.7 per cent, respectively, in the rachitic group compared with 9.8, 2, 1.2, and 43.7 per cent, respectively, in the control group (p < 0.001). Nutritional rickets seems to be a common problem among infants in Jordan. Further studies at national level are needed to determine the prevalence of rickets in Jordan. Rachitic infants are commonly hospitalized due to lower respiratory tract infections, thus there is a high index of suspicion for rickets among hospitalized infants with lower respiratory tract diseases.

RESUMO

BACKGROUND: Iron and zinc deficiency are prevalent during infancy in low-income countries. OBJECTIVES: The objectives were to examine whether a weekly supplement of iron, zinc, iron+zinc, or a micronutrient mix (MM) of 16 vitamins and minerals would alter infant development and behavior. DESIGN: The participants were 221 infants from rural Bangladesh at risk of micronutrient deficiencies. Development and behavior were evaluated at 6 and 12 mo of age by using the Bayley Scales of Infant Development II and the Home Observation Measurement of Environment (HOME) scale. In this double-blind trial, the infants were randomly assigned to 1 of 5 treatment conditions: iron (20 mg), zinc (20 mg), iron+zinc, MM (16 vitamins and minerals, including iron and zinc), or riboflavin weekly from 6 to 12 mo. Multivariate analyses were conducted to examine the change in development and behavior for each supplementation group, with control for maternal education, HOME score, months breastfed, anemia, growth at 6 mo, and change in growth from 6 to 12 mo. RESULTS: Iron and zinc administered together and with other micronutrients had a beneficial effect on infant motor development. Iron and zinc administered individually and in combination had a beneficial effect on orientation-engagement. Two-thirds of the infants were mildly anemic, no treatment effects on hemoglobin concentration were observed, and hemoglobin was not associated with measures of development or behavior. CONCLUSION: The beneficial effects of weekly iron and zinc supplementation on motor development and orientation-engagement suggest that infants benefit from these minerals when administered together.

RESUMO

The genealogy of children's sedatives such as Kio-gan and Kyumei-gan, which remain in use even today for pediatric conditions including convulsions and nocturnal crying, was traced and the significance of these formulas was investigated. In the Edo Era, pediatric formulas for five kinds of gan (infantile malnutrition) combined four prescriptions to treat individual symptoms of "re (heat) gan," "leng (cool) gan," "hui (helminth parasite) gan," and "ji (spinal) gan" into one prescription. In contrast, during and after the Meiji Era, pediatric formulas for these five kinds of gan have used only one prescription to treat "re (heat) gan". Moreover, these formulas have tended to use a greater proportion of components that are used to treat "re gan". From this information, it readily became apparent that : 1) Edo Era pediatric formulas for the five kinds of gan were intended to improve the physical condition of the children prone to the illness; and, 2) modern (Meiji Era) prescriptions were intended to alleviate the acute symptoms of gan.

RESUMO

AIM OF THE STUDY: We analysed the compliance of current recommendations concerning rickets prevention in Poland. MATERIAL AND METHODS: The study group consisted of 65 infants hospitalised because of emergency problems. In each case, the medical history included prophylaxis of rickets and feeding pattern. In most cases (80%) we measured calcium, phosphate, and alkaline phosphatase in the serum. RESULTS: Vitamin D3 was overdosed in 70% of infants. 14% of children were diagnosed as rachitic in outpatient department before hospitalisation, but neither the clinical symptoms nor the laboratory test confirmed the diagnosis. This confirms the observation, that rickets is diagnosed too often, usually on the basis of isolated craniotabes in young infants. CONCLUSION: In the context of changing recommendations for prophylaxis of rickets, we recommend more careful prescribing of vitamin D3 preparations.

RESUMO

La acrodermatitis enteropática es una enfermedad, autosómica recesiva poco frecuente, que se presenta en los primeros meses de vida. Se comunican dos pacientes que presentaron alopecia, dermatitis acral, alteraciones digestivas, además de irritabilidad e infecciones recurrentes. Los estudios de laboratorio confirman niveles bajos de zinc y de fosfatasa alcalina. La terapia sustitutiva con sulfato de zinc produjo una rápida mejoría
