RESUMO

OBJECTIVE: To evaluate whether there is an association between the body mass index z-score and waist-to-height ratio of children and adolescents. METHODS: This was a cross-sectional study conducted in a school in Santo André, SP, between June and August 2019. Body mass index was measured for all participants, adopting the z-score cutoff of +2 recommended by the World Health Organization. The waist-to-height ratio was determined in children over two years of age and considered abnormal when ≥0.5. The qualitative variables are presented as absolute numbers and percentages. To compare qualitative data, we used the χ2 test or Fisher's exact test. Pearson's test was applied to assess the correlation between BMI and waist-to-height ratio. The level of significance adopted was 5%. RESULTS: The body mass index was calculated for 518 children and the waist-to-height ratio for 473 children. Regarding body mass index, 60.6% of the participants had normal weight, 3.1% were underweight, and 36.3% were overweight. overweight (24.7%) and obesity (22.7%) were more prevalent in adolescents. The waist-to-height ratio was abnormal in 50.5% of the sample. There was an increasing association between body mass index and waist-to-height ratio with age, according to the Pearson correlation coefficients for the age groups <5 years (r=0.459; p<0.001), 5 to 10 years (r=0.687; p<0.001) and >10 years (r=0.805; p<0.001). CONCLUSION: There was a significant correlation between body mass index and waist-to-height ratio. This association was higher in adolescents. The waist-to-height ratio is easy to apply and may be useful as a predictor of cardiometabolic risk.

RESUMO

OBJECTIVE: To evaluate the prevalence of breastfeeding in a metropolitan region in Brasil and to identify factors influencing the lack of adherence to exclusive breastfeeding for 6 months and total breastfeeding for 2 years. METHODS: In this cross-sectional study, demographic and socioeconomic characteristics of mothers and children in pediatric outpatient clinics were analyzed. Logistic regression was performed using the backward stepwise method to analyze factors associated with the lack of breastfeeding compliance. RESULTS: In total, 385 mothers who visited the pediatric outpatient clinics were included. Among the mothers, 38.44% reported exclusive breastfeeding for >6 months and 22.6% reported total breastfeeding for 2 years or more. The predictive factors for the lack of adherence to exclusive breastfeeding for 6 months included single mothers (OR=1.976; 95%CI 1.245-3.135; p=0.004), use of a pacifier (OR=2.25; 95%CI 1.436-3.524; p<0.001), and low birth weight (OR=2.21; 95%CI 1.192-4.102; p=0.012). Predictive factors for the lack of adherence to total breastfeeding for 2 or more years included use of a pacifier (OR=4.82; 95%CI 2.722-8.54; p<0.001), planned pregnancy (OR=0.51; 95%CI 0.305-0.875; p=0.014), and breastfeeding in the first hour of life (OR=0.36; 95%CI 0.208-0.641; p<0.001). CONCLUSIONS: The prevalence of exclusive breastfeeding for 6 months and total breastfeeding for 2 years or more was insufficient in the studied population. Several factors were associated with the lower duration of exclusive breastfeeding and total breastfeeding. The use of a pacifier and no breastfeeding in the first hour were preventable factors associated with both modalities.

RESUMO

BACKGROUND: Common variable immunodeficiency (CVID) is an inborn errors of immunity, that leads to recurrent chronic infections and autoimmune/ inflammatory diseases and neoplasms. It is considered that these condition is related to persistent this immune-inflammatory stimulation and increased oxidative stress. A positive impact on the survival of patients with an inborn error of immunity was observed with advanced clinical care protocols, thus raising concerns about the risk of developing other associated chronic diseases, such as atherosclerosis. Studies suggest that selenium (Se) is a protective trace element against damage caused by oxidative stress. Thus, it is postulated that adequate consumption reduces the risk of some chronic diseases. RESULTS: Se median levels (ug/L) [45.6 (37.3-56.2) vs. 57.8 (46.0-66.0); p = 0.004] and GPX activity (U/L) [7682 (6548-8446) vs. 9284(8440-10,720); p = 0,002) were significantly lower in patients compared to controls. Inadequacy of Se levels was observed in 50% of the patients. There was a higher percentage of high values of C-reactive protein in the group of CVID patients compared to controls [8 (36.4%) vs. 2 (11.1%); p = 0.082]. Higher concentrations of oxidized LDL (45.3 mg/dL vs. 33.3 mg/dL; p = 0.016) and lower concentrations of Apo A-1 (98.5 mg/dL) vs. 117.0 mg/dL; p = 0.008) were observed in the CVID group compared to the control. There was a significant and positive correlation between Se plasma levels and apolipoprotein A-1 concentrations in CVID group (rho = 0.577; p = 0.001). Se values less than 46 µg / L (OR = 3.590; 95% CI 1.103 to 11.687; p = 0.034) and GPX activity below the 4th quartile (OR = 21.703; 95% CI 2.534 to 185.914; p = 0.005) were independently associated, after adjustment for age, overweight and dyslipidemia, with the CVID group (Table 5). CONCLUSION: This study showed an higher percentage of high us-CRP, lower values of plasma Se and GPX activity, higher concentrations of LDLox and lower levels of Apo A-1 in CVID patients in comparison to controls, suggesting oxidative stress and cardiovascular risk.These data point to the importance of assessing the Se status and cardiovascular risk in these patients.

RESUMO

BACKGROUND: To describe the biomarkers of lipid metabolism in children and adolescents with polyarticular and systemic JIA and to relate them to diseases subtypes, diseases activity markers, and nutritional status. METHODS: A cross-sectional study including 62 JIA patients was performed. The following variables were evaluated: disease activity and medications used, body mass index, height for age (z-score), skin folds (bicipital, tricipital, subscapular and suprailiac), food intake based on three 24-h food recalls, lipid profile (total cholesterol (CT), low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides (TG) and non-HDL (N-HDLc), glycemia and insulin, erythrocyte sedimentation rate (ESR), ultrasensitive C-reactive protein (us-CRP) and apolipoproteins A-I and B (Apo A-I and Apo B). RESULTS: Dyslipidemia was observed in 83.3% of the patients. Based on classical lipid profile, low HDL-c levels was the most frequently alteration observed. Inadequate levels of LDL-c, Apo B and NHDL-c were significantly more frequent in the systemic JIA subtype when compared to the polyarticular subtype (p = 0.017, 0.001 and 0.042 respectively). Patients on biological therapy had a better adequacy of Apo A-I concentrations. The ESR showed a negative correlation with Apo A-I level (r = - 0.25, p = 0.047). CONCLUSION: We concluded that dyslipidemia is common in patients with JIA, especially in systemic subtype. The systemic subtype and an elevated ESR were associated with lower concentrations of Apo A-I, suggesting the participation of the inflammatory process.

RESUMO

INTRODUCTION: Ataxia-Telangiectasia (A-T) is a multi-system disorder that may be associated with endocrine changes, oxidative stress in addition to inflammation. Studies suggest that selenium is a trace element related to protection against damage caused by oxidative stress. OBJECTIVE: To describe the plasma levels of selenium and erythrocyte glutathione peroxidase activity in A-T patients and to relate them to oxidative stress and lipid status biomarkers. METHODS: This is a cross-sectional and controlled study evaluating 22 A-T patients (age median, 12.2 years old) matched by gender and age with 18 healthy controls. We evaluated: nutritional status, food intake, plasma selenium levels, erythrocyte glutathione peroxidase activity, lipid status, inflammation and oxidative stress biomarkers. RESULTS: Adequate levels of selenium were observed in 24/36 (66.7%) in this evaluated population. There was no statistically significant difference between the groups in selenium levels [47.6 µg/L (43.2-57.0) vs 54.6 (45.2-62.6) µg/dL, p = 0.242]. Nine of A-T patients (41%) had selenium levels below the reference value. The A-T group presented higher levels of LDL-c, non-HDL-c, oxidized LDL, Apo B, Apo-B/Apo-A-I1, LDL-c/HDL-c ratio, malondialdehyde [3.8 µg/L vs 2.8 µg/L, p = 0.029] and lower Apo-A-I1/HDL-c and glutathione peroxidase activity [7300 U/L vs 8686 U/L, p = 0.005]. Selenium levels were influenced, in both groups, independently, by the concentrations of oxidized LDL, malonaldehyde and non-HDL-c. The oxidized LDL (AUC = 0.849) and ALT (AUC = 0.854) were the variables that showed the greatest discriminatory power between groups. CONCLUSION: In conclusion, we observed the presence of selenium below the reference value in nearly 40% and low GPx activity in A-T patients. There was a significant, inverse and independent association between selenium concentrations and oxidative stress biomarkers. Those data reinforce the importance of assessing the nutritional status of selenium in those patients.

RESUMO

Abstract Objective: To evaluate the psychometric properties of the Brazilian version of health-related quality-of-life questionnaires of children with food allergy and their parents. Methods: The translation and cultural adaptation processes were previously performed, according to the method proposed by the World Health Organization. After this stage, the questionnaires were applied to 201 parents of children under 6 years of age with food allergy. The assessment of the psychometric properties included: evaluation of the internal consistency by Cronbach's alpha coefficient; of the reproducibility by the intraclass correlation coefficient between test and retest; and of the construct, using Spearman's correlation coefficient, comparing the obtained scores with those of generic questionnaires that evaluate health-related quality of life. Results: The means of the obtained scores were 2.44 and 3.35, for the children and their parents, respectively. Cronbach's alpha coefficients were 0.85 and 0.91, respectively, which showed good internal consistency of the tools. The intraclass correlation coefficients between test and retest were 0.87 and 0.84 for children and their parents, respectively, showing good reproducibility for both questionnaires. The correlation between the specific and the generic questionnaires was significant (−0.27 for the children, −0.64 for their parents, p < 0.05). Conclusions: The specific questionnaires to evaluate the health-related quality of life of children with food allergy and of their parents were satisfactorily validated to be used in Brazil.


Resumo Objetivo: Avaliar as propriedades psicométricas da versão brasileira dos questionários de qualidade de vida relacionada à saúde de crianças com alergia alimentar e de seus pais. Método: Os processos de tradução e adaptação cultural foram feitos previamente, de acordo com o método proposto pela Organização Mundial da Saúde. Após essa etapa, os questionários foram aplicados a 201 pais de crianças menores de 6 anos com alergia alimentar. A avaliação das propriedades psicométricas incluiu: avaliação da consistência interna, pelo coeficiente alfa de Cronbach; da reprodutibilidade, pelo coeficiente de correlação intraclasse entre teste e reteste; e do constructo, empregou-se o coeficiente de correlação de Spearman, comparando os escores obtidos com os de questionários genéricos que avaliam a qualidade de vida relacionada à saúde. Resultados: As médias dos escores obtidos foram 2,44 e 3,35, para as crianças e seus pais, respectivamente. Os coeficientes alfa de Cronbach foram 0,85 e 0,91, respectivamente, o que demonstrou boa consistência interna dos instrumentos. Os coeficientes de correlação intraclasse entre os testes e os retestes foram 0,87 e 0,84, para crianças e seus pais, respectivamente, demonstraram boa reprodutibilidade para ambos os questionários. A correlação entre os questionários específicos e genéricos foi significante (−0,27 para as crianças; −0,64 para os pais; p < 0,05). Conclusões: Os questionários específicos para avaliar a qualidade de vida relacionada à saúde de crianças com alergia alimentar e de seus pais foram satisfatoriamente validados para uso no Brasil.

RESUMO

OBJECTIVES: To evaluate the treatment of wheezing and exacerbation of asthma in a pediatric emergency unit (ED), comparing it to that recommended by the guidelines for this purpose. METHODS: Descriptive cross-sectional study through medical records survey of children and adolescents (0-15 years of age) who received medication for wheezing or asthma exacerbation from January to April 2015 in the ED. The selected treatment was compared to that recommended by the guidelines, being analyzed the variables related to the medication (number and dose of short-acting ß2 agonist, associated or not with anticholinergic, oral or parenteral corticosteroid) and the length of stay in ED (≤1 h, ≥8 h and hospital admission). RESULTS: One-thousand eleven patients were selected with 56.7% between 3 and 15 years and 56% male. Although the selected drugs were in accordance with what was recommended, errors were observed in relation to dose, drug of choice, and method and time of use with the most frequent finding being incorrect dose (short-acting ß2 agonist: 66% and ipratropium bromide: 95.2%). CONCLUSION: The level of use of the measures recommended by the guidelines was low but compatible with other studies, leading to an increased risk of treatment failure and higher costs. Despite wide dissemination, the established concepts have not been sufficiently incorporated into clinical practice, suggesting the need for more effective educational actions for this process to occur.

RESUMO

AIM: To describe the prevalence of dyslipidemia in children and adolescents with autoimmune rheumatic diseases (ARDs), particularly juvenile idiopathic arthritis (JIA), juvenile systemic lupus erythematosus (jSLE), and juvenile dermatomyositis (JDM). METHODS: Retrospective cross-sectional study conducted in the pediatric rheumatology outpatient clinic. We evaluated 186 children and adolescents between the ages of 5 and 19 years. The medical records were reviewed for the following data: demographic and clinical features, disease activity, and lipid profile (triglycerides (TG), total cholesterol (TC), low density lipoprotein (LDL-C), high density lipoprotein (HDL-C) and very low density lipoprotein (VLDL-C)). In addition, non-HDL cholesterol was calculated as TC minus HDL-C. The cut-off points proposed by the American Academy of Pediatrics were used to classify the lipid profile. RESULTS: Dyslipidemia was observed in 128 patients (68.8%), the most common being decreased HDL-C (74 patients, 39.8%). In the JIA group there was an association between the systemic subtype and altered LDL-C and NHDL-C, which demonstrated a more atherogenic profile in this subtype (p=0.027 and p=0.017, respectively). Among patients with jSLE, the cumulative corticosteroid dose was associated with an increase in LDL-C (p=0.013) and with a decrease in HDL-C (p=0.022). CONCLUSION: Dyslipidemia is common in children and adolescents with ARDs, especially JIA, jSLE, and JDM, and the main alteration in the lipid profile of these patients was decreased HDL-C.

RESUMO

OBJECTIVE: To assess the level of knowledge of emergency pediatricians on red blood cell transfusions and their reactions. METHODS: Written survey with emergency pediatricians from a pediatric hospital. RESULTS: Less than 20% of pediatricians showed appropriate knowledge on prescribing red blood cells and recognition of transfusion reactions. There was no significant statistical regarding time since graduation and blood transfusion classes in undergraduate studies or during medical residency. CONCLUSION: Pediatricians have insufficient knowledge about red blood cell transfusions and recognition of transfusion reactions.

RESUMO OBJETIVOS: Avaliar o tratamento da sibilância e da exacerbação da asma em unidade de emergência pediátrica (DE), comparando-o ao recomendado pelas diretrizes para esse fim. MÉTODOS: Estudo descritivo transversal, por meio do levantamento de prontuários de crianças e adolescentes (0 - 15 anos de idade) que receberam medicação para sibilância ou exacerbação da asma, no período de janeiro a abril de 2015, em DE. O tratamento empregado foi comparado ao preconizado pelas diretrizes sendo analisadas as variáveis referentes à medicação (número e dose de β2 agonista de curta ação, associado ou não a anticolinérgico, corticosteroide oral ou parenteral) e ao tempo de permanência na DE (≤1 h, ≥8 h e internação hospitalar). RESULTADOS: Foram selecionados 1011 pacientes, 56,7% com idades entre 3 e 15 anos e 56 % do sexo masculino. Embora os fármacos utilizados estivessem de acordo com o preconizado, foram observados erros com relação a dose, droga de escolha, forma de utilização, tempo de uso, sendo dose incorreta o achado mais frequente (β2 agonista de curta ação: 66% e brometo de ipratrópio: 95,2%). CONCLUSÃO: O nível de utilização das medidas recomendadas pelas diretrizes foi baixo e compatível com outros estudos, levando a risco aumentado de falha no tratamento e maior custo. Apesar da ampla divulgação, os conceitos estabelecidos não são suficientemente incorporados à prática clínica, sugerindo a necessidade de ações educativas mais efetivas para que isso ocorra.

RESUMO

OBJECTIVE: To compare the classification of the adequacy of birth weight for gestational age applying INTERGROWTH-21 (IG-21) and Fenton growth curves in preterm infants, and to relate this classification to the nutritional status at 12 months corrected age. METHODS: This is a retrospective study with 173 preterm infants aged between 26 and 33 weeks. Data was collected on maternal health conditions, birth and gestational age anthropometric information, and anthropometry (weight, height, and head circumference) at 12 months corrected age. RESULTS: The mean birth weight and gestational age were 1151.4 ± 227.2 g and 30.2 ± 2.4 weeks, respectively. Using percentiles of IG-21 and Fenton curves, the proportion of SGA and LGA preterm infants was 39.2% vs. 35.2%, and 3.5% vs. 3.5%, respectively (p = 0.520). At 12 months corrected age, short stature, overweight, and thinness were observed in 33.5%, 9.9%, and 11% of preterm infants, respectively. The ROC curve evidenced that the IG-21 was slightly better than Fenton to predict short stature (AUC = 0.626, 95% CI 0.537-0.715 and AUC = 0.600, 95% CI 0.506-0.694) and overweight (AUC = 0.648, 95% CI 0.527-0.769 and AUC = 0.618, 95% CI 0.486-0.750) at 12 months corrected age. In contrast, the ROC curve did not show an association of IG-21 and Fenton percentiles with thinness. CONCLUSIONS FOR PRACTICE: This study showed that IG-21 and Fenton were similar for the classification of birth weight for gestational age in preterm infants. IG-21 was slightly better than Fenton to predict overweight and short stature in preterm infants at 12 months corrected age.

RESUMO OBJETIVO Descrever a prevalência de dislipidemias em crianças e adolescentes com doenças reumáticas autoimunes (Drai), em particular artrite idiopática juvenil (AIJ), lúpus eritematoso sistêmico juvenil (Lesj) e dermatomiosite juvenil (DMJ). MÉTODOS Estudo transversal retrospectivo realizado no ambulatório de reumatologia pediátrica. Foram avaliados 186 crianças e adolescentes com idades entre 5 e 19 anos. Foram coletados dos prontuários dados demográficos, clínicos, atividade de doença e perfil lipídico (triglicérides (TG), colesterol total (CT) e frações LDL-c (low density lipoprotein); HDL-c (high density lipoprotein) e VLDL-c (very low density lipoprotein). Foi também calculada a fração não HDL do colesterol (CT-NHDL -c). Para classificação do perfil lipídico, foram adotados os pontos de corte propostos pela American Academy of Pediatrics. RESULTADOS A dislipidemia foi observada em 128 pacientes (68,8%), sendo a mais comum a diminuição do HDL-c em 74 (39,8%). No grupo AIJ houve uma associação entre o subtipo sistêmico com alteração de LDL-c e NHDL-c, mostrando um perfil mais aterogênico neste subtipo (p=0,027 e 0,017, respectivamente). Em relação aos pacientes com Lesj, podemos observar que a dose cumulativa de CTC teve associação com o aumento do LDL-c (p=0,013) e com a diminuição do HDL-c (p=0,022). CONCLUSÃO A dislipidemia é frequente em crianças e adolescentes com Drai, em especial, AIJ, Lesj e DMJ, e a principal alteração no perfil lipídico desses pacientes foi a diminuição do HDL-c.

Background: Fibromyalgia (FM) is a clinical syndrome mainly characterized by generalized chronic pain, fatigue, sleep and cognition disorders. The role played by vitamin D in the pathophysiology of painful syndromes is poorly known. Studies assessing the association between vitamin D and FM have presented conflicting results. The aims of the current study were to assess vitamin D levels in FM patients, by comparing them to healthy controls, as well as to analyze their impact on this disease. Methods: This was a cross-sectional study comprising 43 FM patients (ACR 2010 criteria) and 40 healthy individuals. All participants had their vitamin D levels measured, and FM patients also had their total calcium, albumin, phosphorus and parathyroid hormone (PTH) measured. Clinical variables capable of affecting the results were evaluated and the fibromyalgia impact questionnaire (FIQ) was applied. Results: There was not statistically significant difference in global mean values of vitamin D between groups. In the total sample, only 4.8% of the individuals had vitamin D deficiency, which corresponded to the deficiency found in the group of patients; in the control, no one had vitamin deficiency; 39.8% had insufficient levels and 55.4% with sufficient levels. The mean serum vitamin D values were similar between the FM and control groups (34.8 ± 12 and 34.7 ± 12.3 ng/mL, respectively; P = 0.806). However, a significant negative correlation was found between vitamin D concentration and FIQ values, that is, patients with the greatest impact of the disease had lower concentrations of vitamin D (P = 0.018). Conclusion: FM patients did not present higher prevalence of vitamin D deficiency or insufficiency than healthy individuals, although low vitamin D concentrations could indicate more severe disease impacts.

RESUMO

OBJECTIVE: To evaluate the psychometric properties of the Brazilian version of health-related quality-of-life questionnaires of children with food allergy and their parents. METHODS: The translation and cultural adaptation processes were previously performed, according to the method proposed by the World Health Organization. After this stage, the questionnaires were applied to 201 parents of children under 6 years of age with food allergy. The assessment of the psychometric properties included: evaluation of the internal consistency by Cronbach's alpha coefficient; of the reproducibility by the intraclass correlation coefficient between test and retest; and of the construct, using Spearman's correlation coefficient, comparing the obtained scores with those of generic questionnaires that evaluate health-related quality of life. RESULTS: The means of the obtained scores were 2.44 and 3.35, for the children and their parents, respectively. Cronbach's alpha coefficients were 0.85 and 0.91, respectively, which showed good internal consistency of the tools. The intraclass correlation coefficients between test and retest were 0.87 and 0.84 for children and their parents, respectively, showing good reproducibility for both questionnaires. The correlation between the specific and the generic questionnaires was significant (-0.27 for the children, -0.64 for their parents, p<0.05). CONCLUSIONS: The specific questionnaires to evaluate the health-related quality of life of children with food allergy and of their parents were satisfactorily validated to be used in Brazil.

RESUMO

ABSTRACT Objective To assess the level of knowledge of emergency pediatricians on red blood cell transfusions and their reactions. Methods Written survey with emergency pediatricians from a pediatric hospital. Results Less than 20% of pediatricians showed appropriate knowledge on prescribing red blood cells and recognition of transfusion reactions. There was no significant statistical regarding time since graduation and blood transfusion classes in undergraduate studies or during medical residency. Conclusion Pediatricians have insufficient knowledge about red blood cell transfusions and recognition of transfusion reactions.

RESUMO

OBJECTIVE: To verify the adequacy of platelet concentrate prescription by pediatricians in different pediatric sectors of a general hospital. METHODS: A cross-sectional study evaluating 218/227 platelet concentrate records in children and adolescents (zero to 13 years old), from January 2007 to April 2015, by the pediatricians of the emergency room, sick bay and intensive care unit. The requisitions were excluded in patients with hematological diseases and those without the number of platelets. RESULTS: Children under 12 months received 98 platelet concentrates (45.2%). Most of the transfusions were prophylactic (165; 79%). Regarding the transfusion site, 39 (18%) were in the emergency room, 27 (12.4%) in the sick bay and 151 (69.6%) in the intensive care unit. The trigger, prescribed volume and platelet concentrate subtype were adequate in 59 (28.2%), 116 (53.5%) and 209 (96.3%) of the transfusions, respectively. Patients with hemorrhage presented adequacy in 42 (95.5%), while children without bleeding presented in 17 (10.3%). The most common inadequacy related to volume was the prescription above recommendation (95; 43.8%). Eight platelet concentrates were prescribed with subtype requests without indication. CONCLUSION: The results obtained in this study showed that transfusion of platelet concentrate occurred more adequately in children with active bleeding compared to prophylactic transfusion. There was a tendency to prescribe high volumes and platelet subtypes not justified according to current protocols. The teaching of transfusion medicine should be more valued at undergraduate and medical residency.

RESUMO

Abstract Objective: To describe the frequency of albuminuria in overweight and obese children and adolescents and to relate it to the severity of obesity, pubertal staging, associated morbidities and the glomerular filtration rate. Method: Cross-sectional study including 64 overweight and obese children and adolescents between 5 and 19 years of age. Data collected: weight, height, waist circumference and systemic arterial pressure. Laboratory tests: lipid profile; glycemia and insulin, used to calculate the Homeostasis Model Assessment (HOMA-IR); C-reactive protein; glutamic-pyruvic transaminase and albuminuria in an isolated urine sample (cutoff <30 mg/g). Creatinine was used to calculate the estimated glomerular filtration rate (eGFR, mL/min/1.73 m2). Results: The mean age was 11.6 ± 3.4 years, 32 (50%) and 29 (45.3%) were male and prepubertal. Forty-six (71.9%) had severe obesity. The frequency and median (min/max) of the observed values for albuminuria (> 30 mg/g) were 14 (21.9%) and 9.4 mg/g (0.70, -300.7 mg/g). The mean eGFR was 122.9 ± 24.7 mL/min/1.73 m2. There was no significant correlation between body mass index, pubertal staging, insulin and HOMA-IR with albuminuria values and neither with eGFR. Children with albuminuria tended to have higher values of diastolic blood pressure (75.0 ± 12.2 vs. 68.1 ± 12.4, p = 0.071). Conclusion: Albuminuria, although frequent in children and adolescents with obesity, was not associated with other morbidities and the glomerular filtration rate in these patients.


Resumo Objetivo: Descrever a frequência de albuminúria em crianças e adolescentes com sobrepeso e obesidade e relacioná-la com a gravidade da obesidade, estadiamento puberal, morbidades associadas e com a taxa de filtração glomerular. Método: Estudo transversal incluindo 64 crianças e adolescentes com sobrepeso e obesidade entre 5 e 19 anos de idade. Dados coletados: peso, estatura, circunferência abdominal e pressão arterial sistêmica. Exames laboratoriais: perfil lipídico; glicemia e insulina, utilizados para cálculo do Homeostasis Model Assessment (HOMA-IR); proteína C reativa; transaminase glutâmico-pirúvica e albuminúria em amostra isolada de urina (ponto de corte < 30 mg/g). A creatinina foi utilizada para o cálculo da taxa de filtração glomerular estimada (eTFG, mL/min/1,73m2). Resultados: A média de idade foi 11,6±3,4 anos, 32 (50%) e 29 (45,3%) eram do gênero masculino e pré-púberes. Quarenta e seis (71,9%) apresentavam obesidade grave. A frequência e a mediana (min/max) dos valores observados para albuminúria (> 30 mg/g) foram 14 (21,9%) e 9,4 mg/g (0,70; -300,7 mg/g). A média da eTFG foi 122,9±24,7 mL/min/1,73 m2. Não houve correlação significante entre o índice de massa corporal, estadiamento puberal, insulina e HOMA-IR com os valores de albuminúria e nem com a eTFG. Crianças com albuminúria tiveram tendência a valores mais elevados de pressão arterial diastólica (75,0±12,2 vs 68,1±12,4, p = 0,071). Conclusão: A albuminúria, apesar de frequente em crianças e adolescentes com obesidade, não se associou com outras morbidades e nem com a taxa de filtração glomerular nesses pacientes.

RESUMO

OBJECTIVES: The objective of this study was to evaluate estimated glomerular filtration rates (eGFR) and markers of renal function in very low birthweight (VLBW) children and to relate these parameters to current nutritional status. METHODS: A cross-sectional and controlled study was performed with prepubertal children between ages 5 and 10, including 44 VLBW participants and 30 healthy participants born at full term with an adequate birthweight (control group). The following data were collected: perinatal history; current weight, height and waist circumference; blood pressure (three measures); blood creatinine, urea, uric acid, cystatin-C, and neutrophil gelatinase-associated lipocalin levels; and urine albumin, creatinine, and calcium levels. RESULTS: Blood pressure, eGFR, albuminuria, concentrations of cystatin-C, neutrophil gelatinase-associated lipocalin, uric acid, urea, creatinine, and fractional calcium excretion did not differ between VLBW and control groups. Regarding the VLBW group, there was no difference in eGFR, albuminuria, and other markers of renal injury in overweight or obese children compared with children with a normal body mass index. CONCLUSIONS: Prepubertal children born with VLBW did not have altered renal function, regardless of their current nutritional status.
