RESUMO

Adults who had non-edematous severe acute malnutrition (SAM) during infancy (i.e., marasmus) have worse glucose tolerance and beta-cell function than survivors of edematous SAM (i.e., kwashiorkor). We hypothesized that wasting and/or stunting in SAM is associated with lower glucose disposal rate (M) and insulin clearance (MCR) in adulthood.We recruited 40 nondiabetic adult SAM survivors (20 marasmus survivors (MS) and 20 kwashiorkor survivors (KS)) and 13 matched community controls. We performed 150-minute hyperinsulinaemic, euglycaemic clamps to estimate M and MCR. We also measured serum adiponectin, anthropometry, and body composition. Data on wasting (weight-for-height) and stunting (height-for-age) were abstracted from the hospital records.Children with marasmus had lower weight-for-height z-scores (WHZ) (-3.8 ± 0.9 vs. -2.2 ± 1.4; P < 0.001) and lower height-for-age z-scores (HAZ) (-4.6 ± 1.1 vs. -3.4 ± 1.5; P = 0.0092) than those with kwashiorkor. As adults, mean age (SD) of participants was 27.2 (8.1) years; BMI was 23.6 (5.0) kg/m2. SAM survivors and controls had similar body composition. MS and KS and controls had similar M (9.1 ± 3.2; 8.7 ± 4.6; 6.9 ± 2.5 mg.kg-1.min-1 respectively; P = 0.3) and MCR. WHZ and HAZ were not associated with M, MCR or adiponectin even after adjusting for body composition.Wasting and stunting during infancy are not associated with insulin sensitivity and insulin clearance in lean, young, adult survivors of SAM. These data are consistent with the finding that glucose intolerance in malnutrition survivors is mostly due to beta-cell dysfunction.

RESUMO

Determinar la ocurrencia de la parasitosis intestinal en niños de 3 a 5 años con desnutrición de tipo Kwashiorkor en el Hospital José María Velasco Ibarra en el periodo 2018-2019 ha sido el objetivo de este estudio descriptivo, de corte transversal. La muestra estuvo conformada por 41 infantes realizándole en la consulta externa su valoración clínica para clasificarlo con la enfermedad desnutrición de tipo Kwashiorkor, lo que incluyó un estudio coproparasitológico verificando la ocurrencia de parásitos intestinales en sus muestras fecales. Los resultados arrojaron que el 65,85% de los pacientes son niñas; el 43,90% corresponden al grupo etario de 5 años; IMC reflejo un 14,32 para los niños y 13,42 para las niñas, reflejándose niveles de desnutrición graves, que se corroboran con los resultados de las pruebas de laboratorio con una albumina sérica que oscila entre 2,05 y 2,63, niños anémicos altamente afectados por poliparásitos intestinales, siendo los más frecuentes: T. trichiura (n=34), A. lumbricoides (n=16) y G. lamblia (n=20). En conclusión, la desnutrición relacionada con la ingesta calórico-proteica, puede ser agravada por la ocurrencia de parásitos intestinales, lo que trae como consecuencia un aumento significativo del riesgo de morbi-mortalidad de niños de 3 a 5 años con desnutrición de tipo Kwashiorkor(AU)

To determine the occurrence of intestinal parasitosis in children aged 3 to 5 years with Kwashiorkor-type malnutrition at the José María Velasco Ibarra Hospital in the period 2018- 2019 has been the objective of this descriptive, crosssectional study. The sample consisted of 41 infants, who performed their clinical assessment in the outpatient clinic to classify it with Kwashiorkor-type malnutrition disease, which included a coproparasitological study verifying the occurrence of intestinal parasites in their fecal samples. The results showed that 65.85% of the patients are girls; 43.90% correspond to the age group of 5 years; BMI reflected 14.32 for boys and 13.42 for girls, reflecting levels of severe malnutrition, which are corroborated with the results of laboratory tests with a serum albumin that ranges between 2.05 and 2.63, boys anemic highly affected by intestinal polyparasites, the most frequent being: T. trichiura (n = 34), A. lumbricoides (n = 16) and G. lamblia (n = 20). In conclusion, malnutrition related to caloric-protein intake can be aggravated by the occurrence of intestinal parasites, which results in a significant increase in the risk of morbidity and mortality in children aged 3 to 5 years with Kwashiorkor-type malnutrition(AU)

RESUMO

Kwashiorkor in infancy is typically associated to an underlying disease. Edema, a striking feature of this type of malnutrition, can be difficult to assess in this age group. The typical dermatosis of Kwashiorkor is not fully explained the deficiency of one isolated vitamin or micronutrient. This article presents an infant with cystic fibrosis, who developed Kwashiorkor in the third month of life with extensive cutaneous manifestations. An early, individualized and aggressive nutritional intervention with optimized supplementationof sulfur amino acids, vitamins and micronutrients was established, with impressively recovery of overall nutrition and skin manifestations in a relatively short period of time.

RESUMO

Although uncommon, kwashiorkor continues to occur in developed, but mainly in developing nations. It is a type of protein-calorie malnutrition that occurs in the setting of insufficient protein intake in the presence of sufficient caloric intake. Skin and hair changes should prompt a thorough dietary history and appropriate dietary intervention. We report a case of a 12-month old girl in Belo Horizonte, Minas Gerais, Brazil, who presented with diffuse edema, desquamation, and irritability misdiagnosed as atopic dermatitis. The diagnosis was consistent with kwashiorkor as a result of severe dietary restriction. The mother had placed the child on a severely restrictive diet, consisting only of potatoes, gelatin, and juice as a consequence of the inability to breastfeed. Kwashiorkor is often underdiagnosed or misdiagnosed and if unrecognized or untreated, may be devastating. This makes it imperative that physicians consider this diagnosis, recognize potential risk factors, and be prepared to accurately assess overall nutritional status of patients.

RESUMO

OBJECTIVE: To investigate whether malnutrition survivors had more liver fat than controls and whether marasmus survivors (Ms) had more liver fat than kwashiorkor survivors (Ks). SUBJECTS AND METHODS: We traced 726 of 1336 adults admitted to hospital as infants with a diagnosis of severe acute malnutrition. We used birthweight (BW) from hospital records and measured anthropometry, body composition (DEXA) and liver fat using single, crosssectional computed tomography (CT) scanning at T12/L1 vertebrae. Data were analysed using multivariate line arregression. RESULTS: We studied 45 Ms, 43 Ks and 84 age-, gender and body mass index (BMI)-matched controls (age 29.0 ±8.4 years, BMI 23.5 ± 5.0 kg/m2). Using LS ratio, malnutrition survivors had less liver fat than controls (1.3± 0.2 vs 1.2 ± 0.9, p = 0.03). Marasmus survivors had lower BW than Ks (-0.51 kg; p = 0.02), were younger (p =0.02), had smaller waists (p = 0.03), were thinner (p =0.01) and had less body fat (p = 0.05) compared to Ks.Marasmus survivors had more liver fat than Ks after adjusting for age, gender and BW (â = -2.62, SE = 1.23; p= 0.03). Lower BW infants had less liver fat after adjusting for diagnosis (â = -1.51, SE = 0.76; p = 0.04). CONCLUSION: Fatty liver occurs at lower BMI in Ms compared with Ks; this difference is likely due to both prenatal and postnatal factors acting independently. While further studies are needed to understand the mechanisms involved, our data suggest the need to monitor infants exposed to severe acute malnutrition beyond the acute episode.

RESUMO

Objetivo: comparar el perfil lipídico de niños menores de 5 años con desnutrición aguda con un grupo control. Metodología: estudio descriptivo, de corte transversal, en 43 niños, 26 con desnutrición aguda y 17 con adecuado peso para la talla (P/T). Entre los grupos de estudio se compararon las concentraciones séricas de CT, c-LDL, c-HDL y TG. Resultados: el grupo con desnutrición presentó una frecuencia significativamente mayor de c-HDL bajas comparados con controles (19 vs 7% respectivamente, p=0,036) y un riesgo 1,8 veces mayor de c-HDL bajas (OR=1,8; IC 0,960-3,280). Los TG fueron mayores en los desnutridos, pero sin diferencia significativa con los controles. Las concentraciones de CT, c-LDL y c-HDL disminuyeron significativamente a medida que aumentó el grado de desnutrición, mientras que los TG aumentaron pero no significativamente; en los niños con desnutrición grave el índice arterial TG/c-HDL fue significativamente mayor que en los moderados y en los controles. Los niños con kwashiorkor presentaron las concentraciones más bajas de CT, c-LDL y c-HDL, las más altas de TG y el mayor índice arterial. Conclusiones: los niños con desnutrición aguda grave, especialmente tipo kwashiorkor, presentan concentraciones más bajas de c-HDL y más altas de TG, con un índice arterial alto que los expone a desarrollar ateroesclerosis.

Objective: to compare the lipid profile between preschools with and without acute malnutrition. Methods: a cross sectional study was developed in 43 preschools; 26 with and 17 without acute malnutrition. Malnutrition was assessed by weight for height ratio (P/T). Among the study groups were compared serum levels of TC, c-LDL, c-HDL and TG. Results: malnourished group showed a significantly higher frequency of c-HDL levels classified as lower compared with controls (19 vs 7%, respectively, p = 0.036) and a 1.8 times higher risk to c-HDL levels classified as lower (OR = 1,8; CI 0,960-3,280). TG levels were higher in malnourished, but no significant difference with controls. TC, c-LDL, and c-HDL concentration sincreased significantly by increasing the acute malnutrition degree. TG increased but not significantly, in preschool with severe acute malnutrition arterial index TG/HDL-C was significantly higher thanin control group. The lowest concentrations of TC, LDL-C, and HDL-C were detected in preschool affected by kwashiorkor. The highest TG, and arterial index were detected in preschool affected by kwashiorkor. Conclusions: preschool affected by severe acute malnutrition, especially kwashiorkor, has lower HDL-C concentrations, higher TG, and a high index which exposed them to develop atherosclerosis.

RESUMO

An inadequate and imbalanced intake of protein and energy results in protein-energy malnutrition (PEM). It is known that bone mineral density and serum magnesium levels are low in malnourished children. However, the roles of serum magnesium and endothelin-1 (ET-1) levels in the pathophysiology of bone mineralization are obscure. Thus, the relationships between serum magnesium and ET-1 levels and the changes in bone mineral density were investigated in this study. There was a total of 32 subjects, 25 of them had PEM and seven were controls. While mean serum ET-1 levels of the children with kwashiorkor and marasmus showed no statistically significant difference, mean serum ET-1 levels of both groups were significantly higher than that of the control group. Serum magnesium levels were lower than normal value in 9 (36%) of 25 malnourished children. Malnourished children included in this study were divided into two subgroups according to their serum magnesium levels. While mean serum ET-1 levels in the group with low magnesium levels were significantly higher than that of the group with normal magnesium levels (p < 0.05), mean bone mineral density and bone mineral content levels were significantly lower (p < 0.05). In conclusion, many factors play a role in the pathophysiology of changes in bone mineral density in malnutrition. Our study suggested that lower magnesium levels and higher ET-1 levels might be important factors in changes of bone mineral density in malnutrition. We recommend that the malnourished patients, especially with hypomagnesaemia, should be treated with magnesium early.

El consumo inadecuado y desbalanceado de proteínas y calorías energía conduce a la malnutrición calórico-proteica (MCP). Se sabe que la densidad mineral ósea y los niveles séricos de magnesio son bajos en los ninos malnutridos. Sin embargo, no está claro el papel que desempenan los niveles séricos de magnesio y los niveles séricos de endotelina-1 (ET-1) en la patofisiología de la mineralización del hueso. Por consiguiente, las relaciones entre los niveles séricos de magnesio y los niveles séricos de ET-1, y los cambios en la densidad mineral ósea, constituyen el objeto de investigación de este estudio. Hubo un total de 32 sujetos; 25 de ellos tenían DCP y 7 eran considerados. Si bien los niveles séricos promedios de ET-1 de los ninos con kwashiorkor y marasmo no mostraron diferencia estadística significativa, los niveles séricos promedio de ET-1 de ambos grupos fueron significativamente más altos que los del grupo de control. Los niveles séricos de magnesio estuvieron por debajo del valor normal en 9 (36%) de 25 ninos malnutridos. Los ninos malnutridos incluidos en este estudio fueron divididos en dos sub-grupos según sus niveles de magnesio en suero. Mientras que los niveles séricos promedio de ET-1 en el grupo con niveles bajos de magnesio fueron significativamente más altos que los del grupo con niveles normales de magnesio (p < 0.05), la densidad mineral ósea promedio y los niveles promedio del contenido mineral óseo fueron significativamente más bajos (p < 0.05). En conclusión, muchos factores juegan un papel en la patofisiología de los cambios en la densidad mineral ósea por la malnutrición. Nuestro estudio sugirió niveles más bajos de magnesio y niveles más altos de ET-1 podrían ser factores importantes en los cambios de densidad mineral ósea en la malnutrición. Se recomienda que los pacientes malnutridos, especialmente a causa de hipomagnesemia, sean tratados con magnesio lo más pronto posible.

RESUMO

BACKGROUND: Severe acute malnutrition in childhood manifests as oedematous (kwashiorkor, marasmic kwashiorkor) and non-oedematous (marasmus) syndromes with very different prognoses. Kwashiorkor differs from marasmus in the patterns of protein, amino acid and lipid metabolism when patients are acutely ill as well as after rehabilitation to ideal weight for height. Metabolic patterns among marasmic patients define them as metabolically thrifty, while kwashiorkor patients function as metabolically profligate. Such differences might underlie syndromic presentation and prognosis. However, no fundamental explanation exists for these differences in metabolism, nor clinical pictures, given similar exposures to undernutrition. We hypothesized that different developmental trajectories underlie these clinical-metabolic phenotypes: if so this would be strong evidence in support of predictive adaptation model of developmental plasticity. METHODOLOGY/PRINCIPAL FINDINGS: We reviewed the records of all children admitted with severe acute malnutrition to the Tropical Metabolism Research Unit Ward of the University Hospital of the West Indies, Kingston, Jamaica during 1962-1992. We used Wellcome criteria to establish the diagnoses of kwashiorkor (n = 391), marasmus (n = 383), and marasmic-kwashiorkor (n = 375). We recorded participants' birth weights, as determined from maternal recall at the time of admission. Those who developed kwashiorkor had 333 g (95% confidence interval 217 to 449, p<0.001) higher mean birthweight than those who developed marasmus. CONCLUSIONS/SIGNIFICANCE: These data are consistent with a model suggesting that plastic mechanisms operative in utero induce potential marasmics to develop with a metabolic physiology more able to adapt to postnatal undernutrition than those of higher birthweight. Given the different mortality risks of these different syndromes, this observation is supportive of the predictive adaptive response hypothesis and is the first empirical demonstration of the advantageous effects of such a response in humans. The study has implications for understanding pathways to obesity and its cardio-metabolic co-morbidities in poor countries and for famine intervention programs.
