ABSTRACT

Introducción. La deficiencia de hierro (DH) es la carencia nutricional más prevalente y la principal causa de anemia en lactantes. Existe consenso en la suplementación diaria con hierro como estrategia de prevención; también se demostró que la suplementación semanal es eficaz, pero la evidencia en lactantes es escasa. El objetivo fue comparar la efectividad de la administración diaria de hierro frente a la semanal para la prevención de la anemia por DH del lactante. Población y métodos. Ensayo clínico controlado y aleatorizado. Lactantes atendidos en un centro de salud público, sin anemia a los 3 meses de edad, aleatorizados en tres grupos: suplementación diaria (1 mg/kg/día), semanal (4 mg/kg/semana) o sin suplementación (grupo control con lactancia materna exclusiva [LME]). Se evaluó anemia y DH a los 3 y 6 meses. Se registró grado de adherencia y efectos adversos. Los datos se analizaron con el software R versión 4.0.3. Resultados. Participaron 227 lactantes. A los 6 meses el grupo de lactantes con LME sin suplementación (control) presentó prevalencias de DH y anemia por DH (ADH) mayores que los grupos intervenidos (diario y semanal). DH: 40,5 % vs. 13,5 % y 16,7 % (p = 0,002); ADH: 33,3 % vs. 7,8 % y 10 % (p < 0,001). No hubo diferencias entre los grupos diario y semanal. Tampoco hubo diferencias en el porcentaje de alta adherencia a la suplementación (50,6 % diaria vs. 57,1 % semanal), ni en los efectos adversos. Conclusiones. No se hallaron diferencias significativas en la efectividad entre la administración diaria y semanal para la prevención de ADH del lactante.


Introduction. Iron deficiency (ID) is the most prevalent nutritional deficiency and the main cause of anemia in infants. There is consensus on daily iron supplementation as a preventive strategy; and weekly iron supplementation has also been shown to be effective, but evidence in infants is scarce. The objective of this study was to compare the effectiveness of daily versus weekly iron administration for the prevention of ID anemia (IDA) in infants. Population and methods. Randomized, controlled clinical trial. Infants seen at a public health center, without anemia at 3 months of age, were randomized into 3 groups: daily supplementation (1 mg/kg/ day), weekly supplementation (4 mg/kg/week), or no supplementation (control group with exclusive breastfeeding [EB]). Anemia and ID were assessed at 3 and 6 months old. Adherence and adverse events were recorded. Data were analyzed using the R software, version 4.0.3. Results. A total of 227 infants participated. At 6 months, the group of infants with EB without supplementation(control) had a higher prevalence of ID and IDA than the intervention groups (daily and weekly). ID: 40.5% versus 13.5% and 16.7% (p = 0.002); IDA: 33.3% versus 7.8% and 10% (p < 0.001). There were no differences between the daily and weekly supplementation groups. There were also no differences in the percentage of high adherence to supplementation (50.6% daily versus 57.1% weekly) or adverse events. Conclusions. No significant differences in effectiveness were observed between daily and weekly administration for the prevention of infant IDA.

ABSTRACT

Objective: To evaluate the efficacy and safety of intravenous iron supplementation in patients with recurrent iron deficiency anemia (IDA) . Methods: This retrospective analysis of 90 patients with recurrent IDA from May 2012 to December 2021 was conducted, comparing the efficacy and safety of the intravenous iron therapy group and the oral iron therapy group. Results: Among the 90 patients with recurrent IDA, 20 were males and 70 were females, with a median age of 40 (range: 14-85) years. A total of 60 patients received intravenous iron supplementation and 30 received oral iron supplementation. The hematologic response rates in the intravenous iron group were significantly higher than those in the oral iron group at 4 and 8 weeks after treatment [80.0% (48/60) vs 3.3% (1/30) and 96.7% (58/60) vs 46.7% (14/30), all P<0.001, respectively]. The median increase in hemoglobin levels was also significantly higher in the intravenous iron group than in the oral iron group [38 (4, 66) g/L vs 7 (1, 22) g/L at week 4 and 44.5 (18, 80) g/L vs 19 (3, 53) g/L at week 8, all P<0.001]. The intravenous iron group had a significantly higher proportion of patients who achieved normal hemoglobin levels than the oral iron group (55.0% vs 0 and 90% vs 43.3%, all P<0.001, respectively). Iron metabolism indicators were tested before and after 8 weeks of treatment in 26 and 7 patients in the intravenous and oral iron groups, respectively. The median increase in serum ferritin (SF) levels in the intravenous iron group 8 weeks after treatment was 113.7 (49.7, 413.5) μg/L, and 54% (14/26) of these patients had SF levels of ≥100 μg/L, which was significantly higher than the median increase in SF levels in the oral iron group [14.0 (5.8, 84.2) μg/L, t=4.760, P<0.001] and the proportion of patients with SF levels of ≥100 μg/L (P=0.013). The incidence of adverse reactions was 3.3% (2/60) in the intravenous iron group, which was significantly lower than that in the oral iron group [20.0% (6/30), P=0.015]. Conclusion: Intravenous iron supplementation is more effective for hematologic response, faster hemoglobin increase, and higher iron storage replenishment rates compared with oral iron supplementation in patients with recurrent IDA, and it is well tolerated by patients.

ABSTRACT

Introducción: la anemia y la ferropenia son frecuentes en candidatos a cirugía cardíaca y se asocian a peores resultados posoperatorios. Su manejo no está estandarizado. No existen datos locales sobre prevalencia y pronóstico. Objetivo: evaluar si la anemia no severa y la ferropenia se asocian en nuestro medio a peores resultados posoperatorios en cirugía cardíaca electiva. Método: estudio de cohorte prospectivo en dos centros. Se incluyeron pacientes mayores de 18 años sometidos a cirugía cardíaca electiva. Se conformaron tres grupos: 1) control, 2) ferropenia aislada y 3) anemia no severa. Se consignaron variables clínicas y paraclínicas preoperatorias, intraoperatorias y posoperatorias. Se realizaron análisis uni y multivariados para determinar significancia estadística (p < 0,05). Resultados: se incluyeron 167 pacientes, mediana y distancia IQ 68 años [60-74], 61,68% hombres. FEVI media 59% [45-60], EuroSCORE II 0,96 [0,76-1,35]. Se llevaron a cabo 96 revascularizaciones (57,49%), 39 sustituciones valvulares (23,35%) y 30 combinadas (17,96%), una trombectomía y un implante de tubo aórtico. La prevalencia de ferropenia aislada fue 15,57%, de anemia total 40,72% y de anemia y/o ferropenia 56,29%. El grupo control tuvo menos días de internación (p = 0,0018) y el grupo ferropenia necesitó más volúmenes de glóbulos rojos transfundidos (p = 0,045). En el análisis univariado los grupos 2 y 3 se asociaron a mayores eventos posoperatorios compuestos (OR 2,86, p = 0,03, y OR 2,11, p = 0,03, respectivamente). El grupo 3 se asoció a mayor probabilidad de infección posoperatoria (OR 8,63, 1,03-72,12, p = 0,049). En el análisis multivariado el hematocrito se asoció inversamente a insuficiencia renal (OR 0,61; IC 95% 0,38-0,99, p=0,04) y la edad en forma directa (OR 1,14; IC 95% 1,02-1,28, p=0,02). Conclusiones: la prevalencia de anemia no severa y ferropenia fue alta, se asoció a complicaciones en el posoperatorio y mayor estadía hospitalaria. Es necesario protocolizar su manejo.


Introduction: anemia and iron deficiency are frequent in candidates for cardiac surgery and are associated with poorer postoperative results. Its therapeutic approach is not standardized. There are no local data on prevalence and prognosis. Objective: to assess whether non-severe anemia and iron deficiency are associated with poorer postoperative results in elective cardiac surgery in our patients. Method: prospective cohort study in two centers. Patients > 18 years of age who underwent elective cardiac surgery were included. Three groups were formed: 1) control, 2) isolated iron deficiency and 3) non-severe anemia. Preoperative, intraoperative and postoperative clinical and paraclinical outcomes were recorded. Univariate and multivariate analyzes were performed to determine statistical significance (p < 0.05). Results: 167 patients were included, 68 years [60-74], 61.68% men. Mean LVEF 59% [45-60], EuroSCORE II 0.96 [0.76-1.35]. 96 revascularizations (57.49%), 39 valve replacements (23.35%) and 30 combined (17.96%), one thrombectomy and one aortic tube were carried out. The prevalence of isolated iron deficiency was 15.57%, total anemia 40.72% and anemia and/or iron deficiency 56.29%. The control group had fewer days of hospitalization (p = 0.0018) and the ferropenia group needed more red blood cells transfusions (p = 0.045). In the univariate analysis, groups 2 and 3 were associated with higher compound postoperative events (OR 2.86, p = 0.03, and OR 2.11, p = 0.03, respectively). Group 3 was associated with a higher probability of postoperative infection (OR 8.63, 1.03-72.12, p = 0.049). In the multivariate analysis, the hematocrit values ​​were associated with renal failure (OR 1.14, 95% CI 1.02-1.28, p = 0.02). Conclusions: the prevalence of non-severe anemia and iron deficiency was high, it was associated with greater complications in the postoperative period and a longer hospital stay. It is necessary to protocolize its therapeutic approach.

ABSTRACT

La anemia constituye un problema mayor de salud pública debido a sus múltiples consecuencias biológicas, económicas y sociales. La anemia por deficiencia de hierro es común en niños pequeños, debido a los altos requerimientos de hierro necesarios para su rápido crecimiento y desarrollo, particularmente durante los primeros dos años de vida. Con el objetivo de sintetizar el conocimiento actual sobre los determinantes sociales de la anemia ferropénica en niños, se realizó una revisión sistemática de los artículos originales sobre estudios cuantitativos publicados en las bases de datos PubMed Central (PMC), SCOPUS Elsevier y la Biblioteca Virtual en Salud (BVS) en el mes de febrero del año 2021, en la que fueron seleccionados 43 artículos. Se observa que los estudios abordan desde causas estructurales como el nivel socioeconómico, como aquellas subyacentes: saneamiento, condiciones habitacionales, hacinamiento, conocimiento materno, estado nutricional del niño, lactancia materna y alimentación complementaria, entre otras. Se advierte que hay escasez de estudios en América Latina que aborden la problemática desde la perspectiva de los determinantes sociales, resulta fundamental el profundizar en el estudio de la determinación de las causas para contar con información válida que permita tomar acciones tendientes a contribuir en la resolución de la problemática en Uruguay.


Anemia is a major public health problem due to its multiple biological, economic and social con-sequences. Iron deficiency anemia is common in young children, due to the high iron requirements necessary for their rapid growth and development, particularly during the first two years of life. With the aim of synthesizing the current knowledge on the social determinants of iron deficiency anemia in children, a systematic review of the original articles on quantitative studies published in the PubMed Central (PMC), SCOPUS Elsevier and the Virtual Library in Health (VHL) in the month of February of the year 2021, in which 43 articles were selected. It is observed that the studies address from structural causes such as socioeconomic level, as well as those underlying: sanitation, housing conditions, overcrowding, maternal knowledge, nutritional status of the child, breastfeeding and complementary feeding, among others. It is noted that there is a lack of studies in Latin America that address the problem from the perspective of social determinants, it is essential to deepen the study of the determination of the causes to have valid information that allows taking actions aimed at contributing to the resolution of the problem in Uruguay.

ABSTRACT

OBJECTIVES@#To study the efficacy of intermittent iron supplementation in children with mild iron-deficiency anemia.@*METHODS@#A total of 147 children with mild iron-deficiency anemia were enrolled in this prospective study. They were divided into an intermittent iron supplementation group (n=83) and a conventional iron supplementation group (n=64). The levels of hemoglobin were measured before treatment and after 1 and 3 months of treatment. The treat response rate and the incidence rate of adverse drug reactions were compared between the two groups.@*RESULTS@#Both groups had a significant increase in the level of hemoglobin after iron supplementation (P<0.05). After 1 month of treatment, the conventional iron supplementation group had a significantly higher treatment response rate than the intermittent iron supplementation group (61% vs 42%, P<0.05). After 3 months of treatment, there was no significant difference in the treatment response between the two groups (86% vs 78%, P>0.05). The incidence rate of adverse drug reactions in the conventional iron supplementation group was significantly higher than that in the intermittent iron supplementation group (25% vs 8%, P<0.05).@*CONCLUSIONS@#For children with mild iron-deficiency anemia, although intermittent iron supplementation is inferior to conventional iron supplementation in the short-term efficacy, there is no significant difference in the long-term efficacy between the two methods, and compared with conventional iron supplementation, intermittent iron supplementation can reduce the incidence of adverse drug reactions, alleviate family financial burdens, and improve treatment compliance of children, thus holding promise for clinical application.

ABSTRACT

Resumo Contexto A úlcera varicosa (UV) é o estágio mais avançado da doença venosa crônica (DVC) dos membros inferiores (MMII), frequentemente associada a episódios de hemorragia que podem provocar anemia crônica (AC) e retardar a sua cicatrização. Não há, na literatura, trabalhos que avaliem a prevalência da AC nos portadores de UV dos MMII, e poucos trabalhos analisam o uso da pentoxifilina no tratamento das UV dos MMII. Objetivos Avaliar a prevalência da AC nos pacientes portadores de UV de MMII e a resposta terapêutica ao sulfato ferroso (SF) e a associação da pentoxifilina com SF no tratamento adjuvante das UV dos MMII. Métodos Foram avaliados 67 pacientes portadores de UV de MMII atendidos no ambulatório de Cirurgia Vascular do Hospital das Clínicas, Recife, PE. Após as avaliações clínica e laboratorial iniciais, os pacientes diagnosticados com AC foram randomizados em dois grupos: o grupo controle, que recebeu SF (900 mg/dia via oral), e o grupo de estudo, tratado com SF (900 mg/dia via oral) e pentoxifilina (1.200 mg/dia). Todos foram reavaliados após 90 dias. Resultados Entre os pacientes avaliados, 27 (40%) apresentavam AC. Após o tratamento, foram observados aumento dos níveis de hemoglobina e de hematócrito e melhora das taxas da cinética do ferro, assim como a diminuição da profundidade e da área das UV em ambos os grupos, sem diferença estatística. Conclusões Foi encontrada alta prevalência de anemia na população estudada. A associação do SF com a pentoxifilina não se mostrou mais eficaz do que o emprego isolado do SF no tratamento adjuvante da UV dos MMII.


Abstract Background Venous ulcers (VU) are the most advanced stage of chronic venous disease (CVD) of the lower limbs. They are frequently associated with episodes of hemorrhage that can provoke chronic anemia (CA), delaying healing. There are no studies in the literature analyzing the prevalence of CA among patients with VU of the lower limbs and few studies have analyzed use of pentoxifylline to treat VU of the lower limbs. Objectives To evaluate the prevalence of CA in patients with lower limb VU and responses to treatment with ferrous sulfate (SF) compared with a combination of SF plus pentoxifylline as adjuvant treatment for VU of the lower limbs. Methods A total of 67 patients with lower limb VU were recruited from a Lymphedema and Angiodysplasia Clinic at the Hospital das Clínicas, Recife, PE, Brazil. After initial clinical and laboratory assessments, patients diagnosed with CA were randomized into one of two groups: a control group, given SF (900 mg/day oral route), or a study group, treated with SF (900 mg/day oral route) and pentoxifylline (1,200 mg/day). All were reassessed after 90 days. Results Twenty-seven patients (40%) had CA. After treatment, increases were observed in hemoglobin and hematocrit levels, iron kinetics had improved, and both depth and area of VU had reduced in both groups, without statistically significant differences. Conclusions A high prevalence of anemia was detected in the study population. The combination of SF and pentoxifylline was not more effective than SF alone for adjuvant treatment of VU of the lower limbs.

ABSTRACT

BACKGROUNDS@#Previous surveys have found that children with iron deficiency (ID) were likely to suffer from early childhood caries (ECC). We aimed to assess the scientific evidence about whether ID is intrinsically related to ECC.@*METHODS@#The medical subject headings (MeSH) terms and free words were searched on PubMed, Web of Science, Cochrane, China National Knowledge Infrastructure, Wanfang, and the Database for Chinese Technical Periodicals from March 2020 to September 2020. Two researchers independently screened the articles. Data extraction and cross-checking were performed for the studies that met the inclusion criteria. Meta-analysis was performed using the Cochrane Collaboration's Review Manager 5.3 software.@*RESULTS@#After excluding duplication and irrelevant literature, 12 case-control studies were included in the study. The meta-analysis demonstrated that children with ECC were more likely to have ID (odds ratio [OR] = 2.63, 95% confidence interval [CI]: [1.85, 3.73], P < 0.001). There was no statistically significant association found between the level of serum ferritin and ECC (weighted mean difference (WMD) = -5.80, 95% CI: [-11.97, 0.37], P = 0.07). Children with ECC were more likely to have iron-deficiency anemia (OR = 2.74, 95% CI: [2.41,3.11], P < 0.001). The hemoglobin (HGB) levels in the ECC group were significantly lower compared with that in the ECC-free group (WMD = -9.96, 95% CI: [-15.45, -4.46], P = 0.0004). The mean corpuscular volume (MCV) levels in the ECC group were significantly lower compared with that in the ECC-free group (WMD = -3.72, 95% CI: [-6.65, -0.79], P = 0.01).@*CONCLUSIONS@#ID was more prevalent in children with ECC, and the markers of iron status in the ECC group, such as serum ferritin, HGB, and MCV, were relatively lower than the ECC-free group.

ABSTRACT

ABSTRACT BACKGROUND: Data regarding the prevalence of anemia in inflammatory bowel disease (IBD) patients are scarce in Brazil. Anemia and iron deficiency anemia have been known to cause significant functional impairment, lower quality of life, and higher morbidity and mortality and may be correlated with an impact on the cost of treatment. OBJECTIVE: The aim of this study was to estimate the prevalence and risk factors for anemia and iron deficiency anemia in patients with IBD in a tertiary IBD unit in Southeast Brazil. METHODS: We conducted an Institutional Review Board-approved retrospective analysis of an adult IBD cohort (IBD Unit, Ribeirão Preto Medical School, University of São Paulo, Brazil) consisting of 579 patients between January 2014 and July 2018. Clinicoepidemiological data, hemoglobin measurements and serum ferritin were extracted from electronic medical records. Anemia prevalence was calculated among ulcerative colitis (UC) and Crohn's disease (CD) phenotypes. Risk factors for anemia were also calculated. RESULTS: A total of 529 (91%) patients had complete blood counts available in their medical records. Only 35.5% of IBD patients were fully screened for anemia. The prevalence of anemia in IBD patients was 24.6% (29.1% in CD and 19.1% in UC, P=0.008). The anemia was moderate to severe in 16.9% (19.8% in CD and 11.4% in UC, P=0.34). The prevalence of iron deficiency was 52.3% (53.6% in CD and 51.2% in UC, P=0.95). Anemia of chronic disease was present in 14.1% of IBD patients. A total of 53.8% of patients with anemia were in clinical remission. CD was associated with an increased prevalence of anemia (P=0.008; OR=1.76; CI 95% =1.16-2.66) compared to UC. The penetrant disease phenotype in CD was associated with a lower risk of anemia (P<0.0001; OR=0.25; CI 95% =0.14-0.43). Active disease compared to the disease in clinical remission was associated with an increased risk of anemia (P=0.0003; OR=2.61; CI 95% =1.56-4.36) in CD. The presence of anemia was less frequent in patients with CD who underwent surgical bowel resection compared to those who did not undergo surgery (P<0.0001; OR=0.24; CI 95% =0.14-0.40). No differences in anemia prevalence were observed regarding CD localization, age at diagnosis, UC extension or biological therapy (P>0.05). CONCLUSION: Despite the low levels of full screening, anemia and iron deficiency anemia were common manifestations of IBD. CD was associated with an increased risk of anemia, especially with active disease. In addition, patients with CD who underwent surgical bowel resection and penetrant disease phenotype in CD were associated with lower risk of anemia.


RESUMO CONTEXTO: Dados referentes à prevalência de anemia em pacientes com doença inflamatória intestinal (DII) são escassos no Brasil. Sabe-se que anemia e a anemia ferropriva causam comprometimento funcional significativo, menor qualidade de vida e maior morbimortalidade e podem estar correlacionadas com um impacto no custo do tratamento. OBJETIVO: O objetivo deste estudo foi estimar a prevalência e os fatores de risco de anemia e de anemia ferropriva em pacientes com DII em um centro de referência de DII no Sudeste do Brasil. MÉTODOS: Realizamos uma análise retrospectiva dos pacientes com DII adultos, aprovada pelo Comitê de Ética Institucional do Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo, Brasil, constituída por 579 pacientes no período de janeiro de 2014 a julho de 2018. Dados clínico-epidemiológicos, níveis de hemoglobina e de ferritina sérica foram obtidos dos prontuários eletrônicos. A prevalência de anemia foi calculada entre os fenótipos de retocolite ulcerativa (RCU) e doença de Crohn (DC). Fatores de risco para anemia também foram calculados. RESULTADOS: Um total de 529 (91%) pacientes tinha disponível o exame de hemograma completo em seus prontuários médicos. Apenas 35,5% dos pacientes com DII tinha o rastreamento completo para anemia. A prevalência de anemia nos pacientes com DII foi de 24,6% (29,1% na DC e 19,1% na RCU, P=0,008). A anemia foi moderada a grave em 16,9% (19,8% na DC e 11,4% na RCU, P=0,34). A prevalência de deficiência de ferro foi de 52,3% (53,6% na DC e 51,2% na RCU, P=0,95). Anemia de doença crônica estava presente em 14,1% dos pacientes com DII. Um total de 53,8% dos pacientes com anemia estavam em remissão clínica. A DC esteve associada a um aumento da prevalência de anemia (P=0,008; OR=1,76; IC 95% =1,16-2,66) em comparação à RCU. O fenótipo da doença penetrante na DC foi associado a um menor risco de anemia (P<0,0001; OR=0,25; IC 95% =0,14-0,43). A doença ativa comparada à doença em remissão clínica foi associada a um risco aumentado de anemia (P=0,0003; OR=2,61; IC 95% =1,56-4,36) na DC. A presença de anemia foi menos frequente nos pacientes com DC submetidos à ressecção intestinal em comparação aos que não foram submetidos à cirurgia (P<0,0001; OR=0,24; IC 95% =0,14-0,40). Não foram observadas diferenças na prevalência de anemia em relação à localização da DC, idade ao diagnóstico, extensão da RCU ou terapia biológica (P>0,05). CONCLUSÃO: Apesar do baixo rastreamento completo, tanto a anemia como a anemia ferropriva foram manifestações comuns da DII. A DC foi associada a um risco aumentado de anemia, especialmente com doença ativa. Além disto, pacientes com DC submetidos a ressecção intestinal e/ou com fenótipo penetrante tiveram menor risco de anemia.

ABSTRACT

Introduction: children from native communities are exposed to inequities and inequalities in nutrition and oral health. Objective: determine the relationship between iron-deficiency anemia and the prevalence of dental caries among schoolchildren from Peruvian native communities. Methods: a cross-sectional study was conducted of children from the native communities in Satipo, Junín, Peru. The sample was 120 schoolchildren aged 6-12 years selected according to inclusion and exclusion criteria and in compliance with the ethical standards of scientific research. Hemoglobin concentration was measured with the system HemoCue®. Evaluation of the nutritional status was based on body mass index. Oral conditions were assessed with the following indicators: rate of tooth decay, loss and fillings, significant caries index, simplified oral health index and index of clinical consequences of untreated dental caries. Data were analyzed with the software STATA v. 14. Association between the variables was estimated with the chi-square test. A value of p < 0.05 was considered to be statistically significant. Results: mean hemoglobin concentration was 11.9 mg/dl (1.49); prevalence of anemia was 44.16 percent: most schoolchildren were undernourished: 109 (90.83 percent). Prevalence, experience and significance of dental caries was 93.33 percent, 5.23 and 7.51, respectively. An association was observed between iron-deficiency anemia and the prevalence of dental caries (p=0.011). Conclusions: a statistically significant association was found between the variables studied (p> 0.05)(AU)

ABSTRACT

ABSTRACT Objective: To analyze the association of anemia with the socioeconomic vulnerability of preschoolers in public day care centers, in the city of Taubaté, SP, Brazil. Methods: This is a cross-sectional study with a probabilistic sample that analyzed 363 children assisted in public day care centres in low-income and high-income areas of Taubaté, SP, Brazil. The hemoglobin concentration (Hb), dependent variable, was obtained by digital puncture, considering anemic children with Hb concentration <11.0 g/dL. The independent variables such as socioeconomic and demographic conditions were collected by a semi-structured questionnaire. Results: The prevalence of iron deficiency anemia was 19.3% among preschoolers. Children from day care centers with high socioeconomic vulnerability had lower Hb concentration than those from a non-vulnerable area (p<0.05). Conclusions: The lower concentration of hemoglobin in preschoolers is associated with the location of day care centers in an area of socioeconomic vulnerability. Children attending these day care centers face adverse family conditions such as low income, working mothers, and mothers with low schooling, though they receive social benefits and monitoring by public health services.


RESUMO Objetivo: Analisar a associação da anemia com a vulnerabilidade socioeconômica de pré-escolares de creches públicas da cidade de Taubaté, SP, Brasil. Métodos: Trata-se de um estudo transversal com amostra probabilística que analisou 363 crianças assistidas em creches públicas de regiões de baixa e alta renda de Taubaté. A concentração de hemoglobina (Hb), variável dependente, foi obtida por meio de punção digital, considerando anêmicas as crianças com concentração de Hb<11,0 g/dL. As variáveis independentes como condições socioeconômicas e demográficas foram coletadas por questionário semiestruturado. Resultados: A prevalência de anemia por deficiência de ferro foi de 19,3% entre os pré-escolares. As crianças das creches de elevada vulnerabilidade socioeconômica apresentaram concentração de Hb estatisticamente menor do que aquelas de região não vulnerável (p<0,05). Conclusões: A menor concentração de Hb em pré-escolares está associada à localização das creches em região de vulnerabilidade socioeconômica, uma vez que as crianças que frequentam tais creches enfrentam condições adversas familiares, como baixa renda, mães que trabalham e com baixa escolaridade, embora recebam benefício social e acompanhamento pelos serviços públicos de saúde.

ABSTRACT

La deficiencia de hierro es la causa más frecuente de anemia en pediatría. Su detección precoz, tratamiento correcto y profilaxis adecuada, constituyen una prioridad sanitaria en nuestro país. Objetivo: Describir el screening de hemoglobina realizado en lactantes con edades comprendidas entre 8 y 12 meses, usuarios de un centro de atención pediátrico de Montevideo, en el período comprendido entre 2 de mayo y 31 de octubre de 2015 y evaluar factores de riesgo de anemia ferropénica presentes. Se revisaron sus historias clínicas, consignando datos epidemiológicos, antecedentes perinatales, alimentación recibida y si recibieron suplementación con hierro adecuada. Se registró si se había realizado la medición de hemoglobina por punción digital y el valor medido. Se comparó la prevalencia de factores de riesgo entre niños con y sin anemia. En el período evaluado fueron asistidos 62 niños: 3 pretérminos de 34 semanas o menos; 15 con peso al nacer menor a 3000 gramos; 42 con lactancia materna exclusiva durante 6 meses; 54 con alimentación complementaria adecuada; 45 con suplementación de hierro. Se realizó la medición de hemoglobina por punción digital a 55 niños. Tenían anemia 28 niños (82 % leve). No se encontró asociación de padecer anemia con los factores de riesgo estudiados excepto el cumplimiento de la profilaxis con suplemento de hierro. Concluimos que la prevalencia de anemia en este grupo fue elevada y que la suplementación con hierro es importante para su prevención.


Iron deficiency is the most frequent cause of anemia in pediatrics. Its early detection, correct treatment and adequate prophylaxis, constitute a health priority in our country. Objective: Describe the hemoglobin screening performed in infants aged between 8 and 12 months, users of a pediatric care center from Montevideo, in the period covered between May 2 and October 31, 2015 and evaluate factors of Risk of iron deficiency anemia present. Their clinical histories were reviewed, including epidemiological data, perinatal records, and diet received and if they received adequate iron supplementation. It was recorded if the hemoglobin measurement had been performed by digital puncture and the measured value. The prevalence of risk factors among children with and without anemia was compared. In the evaluated period, 62 children were assisted: 3 preterm subjects of 34 weeks or less; 15 birth weight less than 3,000 grams; 42 exclusive breastfeeding for 6 months; 54 adequate complementary feeding; 45 iron supplementation. The hemoglobin was measured by digital puncture to 55 children. 28 of them had anemia (82 % mild). No association of anemia was found with the risk factors studied except compliance with prophylaxis with iron supplementation. We conclude that the prevalence of anemia in this group was high and that iron supplementation is important for its prevention.

ABSTRACT

Abstract Introduction: Anemic patients with chronic kidney disease (CKD) can be divided into anemic patients without or with functional iron deficiency (FID). The increase in the number of cases of hemosiderosis in patients on hemodialysis (HD) attributed to excessive intravenous iron replacement has called for the investigation of the factors involved in the genesis of FID. Objectives: This study aimed to describe the prevalence of FID in patients with CKD on HD, characterize the included individuals in terms of clinical and workup parameters, and assess their nutritional, oxidative stress, and inflammation statuses. This cross-sectional study assembled a convenience sample of 183 patients with CKD on HD treated in Southern Brazil. Patients meeting the inclusion and exclusion criteria were divided into two groups, one with anemic subjects with FID and one with anemic patients without FID. Participants answered a questionnaire probing into socio-epidemiological factors, underwent anthropometric measurements, and were tested for markers of anemia, oxidative stress, inflammation, and nutrition. Statistical analysis: The date sets were treated on software package GraphPad InStat version 3.1. Variables were tested with the Kolmogorov-Smirnov, chi-square, Student's t, and Mann-Whitney tests. Statistical significance was attributed to differences with a p < 0.05. Results: Markers of inflammation were not statistically different between the two groups. Markers of anemia and nutrition were significantly lower in patients with FID. Patients with FID were prescribed higher doses of parenteral iron (p < 0,05). Discussion: FID was associated with lower nutritional marker levels, but not to increased levels of markers of inflammation or oxidative stress, as reported in the literature. Additional studies on the subject are needed.


Resumo Introdução: A anemia na DRC pode ser dividida em anemia sem deficiência funcional de ferro e com deficiência funcional de ferro (ADFF). Diante do aumento dos casos de hemossiderose em pacientes em hemodiálise, atribuídos à reposição excessiva de ferro endovenoso, maiores conhecimentos sobre os fatores envolvidos na gênese da ADFF são importantes. Objetivos: documentar a prevalência de ADFF em renais crônicos em hemodiálise. Caracterizar clínica e laboratorialmente os portadores de ADFF em HD e avaliar o estado nutricional, estresse oxidativo e inflamatório. Estudo transversal, amostra de conveniência, envolvendo 183 renais crônicos em hemodiálise no sul do Brasil. Após aplicação dos critérios de exclusão, os pacientes foram separados em dois grupos: portadores de anemia com e sem deficiência funcional de ferro. Foram submetidos a questionário socioepidemiológico, à análise antropométrica e análise laboratorial dos marcadores de anemia, estresse oxidativo, inflamatórios e nutricionais. Análise estatística: programa GraphPad InStat versão 3.1. Foram aplicados os testes: Kolmogorov-Smirnov, qui-quadrado, t de Student e Mann-Whitney. Nível de significância adotado de 5%. Resultados: não houve diferença significativa nos marcadores inflamatórios entre os dois grupos. Houve diferença significativa nos marcadores de anemia e nutrição, significativamente menores nos pacientes com ADFF. Pacientes com ADFF receberam doses mais elevadas de ferro parenteral (p < 0,05). Discussão: ADFF esteve associada a menores valores de marcadores nutricionais, mas não esteve associada a marcadores inflamatórios ou de estresse oxidativo aumentados, como relatado na literatura. Estudos adicionais sobre o tema são necessários.

ABSTRACT

ABSTRACT Restless legs syndrome (RLS) is a frequent complication of hemodialysis that has been associated with poor quality of life and increased risk for complications. Nevertheless, few studies regarding this entity exist in resource-limited settings. Objectives: To determine the prevalence of RLS among Mexican patients on hemodialysis; and compare these patients with a control group of the same population. Methods: We recruited 105 hemodialysis patients. Restless legs syndrome was diagnosed according to the updated criteria set out by the International RLS Study Group. We selected patients who did not meet the criteria, as controls. Results: We found an RLS prevalence of 18%. The RLS patients had a significantly higher prevalence of iron deficiency anemia and uremic pruritus. None of the patients reported RLS symptoms prior to hemodialysis initiation. Conclusions: Restless legs syndrome is common among Mexican patients on hemodialysis. Larger studies are required to address the impact of RLS in hemodialysis patients.


RESUMEN El síndrome de piernas inquietas (SPI) es una complicación de la hemodiálisis que se ha asociado con menor calidad de vida y riesgo aumentado de complicaciones. Sin embargo, existen pocos estudios acerca de esta entidad en escenarios de recursos limitados. Objetivos: Determinar la prevalencia de SPI en pacientes mexicanos en hemodiálisis, y comparar las características con un grupo control de la misma población. Métodos: Reclutamos 105 pacientes en hemodiálisis. El SPI se diagnosticó de acuerdo con los criterios actualizados del grupo de estudio internacional del síndrome de piernas inquietas. Seleccionamos a los pacientes que no cumplieron dichos criterios como controles. Resultados: Encontramos una prevalencia de SPI del 18%. Los pacientes con SPI tenían una prevalencia más alta de anemia ferropénica, y prurito urémico. Ninguno de los pacientes reportó síntomas de SPI previo a iniciar la hemodiálisis. Conclusiones: El SPI es frecuente en pacientes mexicanos en hemodiálisis; se requieren estudios más grandes para evaluar el impacto del síndrome en ésta población.

ABSTRACT

Introducción.La vitamina D afecta la eritropoyesis.Objetivo: evaluar, en niños de 6 meses a 5 años, la asociación entre concentraciones de 25-hidroxi vitamina D (25-OHD) en la madre/niño, ferropenia y anemia ferropénica (AF). Población y métodos. Se incluyeron los niños que asistieron a la consulta entre septiembre de 2014 y enero de 2016. Se excluyeron aquellos con infección aguda/crónica, desnutrición, enfermedades crónicas y prematuros. Se realizó hemograma, hierro sérico, capacidad fijación del hierro, ferritina y 25-OHD. Se investigó suplemento con hierro y vitamina D durante lactancia y embarazo.Resultados. Se incluyeron 117 niños: 67 tenían ferropenia/AF [Grupo 1, edad (años): 2,05 ± 1,24 (0,5-5)] y 50 niños sanos [Grupo 2, edad (años): 1,87 ± 1,12 (0,58-5)]. Más niños y madres tuvieron deficiencia de vitamina D en Grupo 1 que en Grupo 2 (niños, 49,3 % vs 20 %, p = 0,002, y madres: 94 % vs 64 %; p= < 0,001, respectivamente). Hubo correlación positiva entre la hemoglobina en niños y la 25-OHD en madres/niños. Factores independientes de riesgo de AF fueron más tiempo de lactancia (OR: 0,35; IC 95 % [0,155-0,789]; p = 0,011), más breve suplementación con hierro durante la lactancia (OR: 1,69; IC 95 % [1,148-2,508]; p = 0,008) y embarazo (OR: 1,39; IC 95 % [1,070-1,820]; p = 0,014) y concentraciones < 25-OHD en madres (OR: 1,16; IC del 95 % [1,034-1,292]; p = 0,011). Conclusiones. La deficiencia de vitamina D en madres/niños está asociada con ferropenia/AFen los niños.


Introduction. Vitamin D (VitD) affects the erythropoiesis. The aim of this study was to evaluate the association between maternal/child 25-OH VitD (25-OHD) levels and iron deficiency (ID) and anemia (IDA) in children aged 6 months-5 years. Population and methods. Between September 2014 and January 2016 children who were admitted to outpatient clinic were included to study. We excluded the children with acute or chronic infection, malnutrition, chronic disease and preterm birth history. Complete blood count, serum iron, total iron binding capacity, ferritin, 25-OHD levels were examined from children and their mothers. Iron and VitD supplementation during infancy and pregnancy and breastfeeding history were questioned.Results. The study included totally 117 children. There were 67 children with ID/IDA [Group 1, mean age (years):2.05±1.24 (0.5-5)] and 50 normal children [Group 2, mean age (years): 1.87±1.12 (0.58-5)]. There were more VitD deficient children and mothers in Group 1 than in Group 2 (respectively, children 49.3 % vs. 20 % p=0.002; mothers 94 % vs.64 %, p=<0.001). There was a positive correlation between hemoglobin levels of children and maternal/child 25-OHD. The independent risk factors for IDA in children were longer exclusively breastfeeding time (odds ratio [OR], 0.35; 95 % confidence interval [CI], 0.155-0.789; p=0.011), shorter duration of regular iron supplementation during infancy and pregnancy (infancy: OR,1.69; 95 % CI 1.148-2.508; p=0.008. pregnancy: OR,1.39; 95 % CI,1.070-1.820; p=0.014) and lower maternal 25-OHD level (OR,1.16; 95 % CI,1.034-1.292; p=0.011). Conclusions. Maternal/child VitD deficiency is associated with ID/IDA in children aged 6 months-5 years.

ABSTRACT

Resumo Objetivou-se revisar os indicadores de insegurança alimentar e nutricional associados à anemia ferropriva em crianças brasileiras menores de 5 anos. Realizou-se busca em bases eletrônicas (ScieLO, Lilacs, Medline), com seleção dos estudos pelos títulos, resumos e pela leitura na íntegra. Dos 1023 trabalhos analisados, 11 contemplaram os critérios de inclusão. Os resultados dos estudos retrataram que a anemia ferropriva em crianças brasileiras associou-se aos indicadores sociodemográficos e de saúde (sexo masculino, idade inferior aos 24 meses, filhos de mães adolescentes, infecções respiratórias, diarreias, baixa escolaridade materna, condição de trabalho dos pais, tempo de creche, ausência de saneamento básico, anemia materna, não uso de sulfato ferroso pela mãe e/ou criança e início tardio do pré-natal), indicadores nutricionais (baixo peso ao nascer, características da dieta como, hábito de ingerir leite próximo dos horários das refeições, baixo tempo de aleitamento materno exclusivo e total) e econômicos (baixa renda per capita). A insegurança alimentar e nutricional, analisada no presente estudo sob a óptica de diferentes indicadores, está associada à ocorrência de anemia ferropriva em crianças menores de 5 anos no Brasil.


Abstract This study aimed to review food and nutrition insecurity indicators associated with iron deficiency anemia in Brazilian children below 5 years. We searched in electronic databases (SciELO, Lilacs, and Medline) and selected studies by titles, abstracts and full-text reading. Of the 1,023 studies analyzed, 11 fit the inclusion criteria. The results of the studies evidenced that iron deficiency anemia in Brazilian children was associated with sociodemographic and health indicators (male, age below 24 months, children of adolescent mothers, respiratory infections, diarrhea, low maternal schooling, parents' working conditions, nursery time, lack of basic sanitation, maternal anemia, lack of ferrous sulfate use by the mother and/or child and late onset of prenatal care), nutritional indicators (low birth weight, diet characteristics, such as the habit of milk consumption close to meals, low exclusive and full breastfeeding time) and economic indicators (low per capita income). The food and nutrition insecurity analyzed in this study from the perspective of different indicators is associated with iron deficiency anemia in children under 5 years in Brazil.

ABSTRACT

Introdução - A anemia ferropriva, um importante problema de saúde pública tanto nos países em desenvolvimento quanto nos desenvolvidos, afeta principalmente as crianças menores de cinco anos de idade e as mulheres em idade reprodutiva. Objetivo - Analisar a taxa de hemoglobina e a prevalência de anemia em mães cujos filhos menores de 5 anos de idade frequentam creches públicas de um município de elevado Índice de Desenvolvimento Humano. Métodos - Estudo de corte transversal. A amostra foi constituída por 230 pares de mães biológicas com idade entre 15 e 49 anos e seus filhos, menores de cinco anos de idade, que frequentavam creches públicas no município de Taubaté-SP. A coleta de dados foi realizada por meio de questionário preenchido pelos responsáveis pela criança e de formulário aplicado às mães, para obter informações sobre fatores socioeconômicos e de saúde da mulher e da criança. Da mãe e de seu respectivo filho foram verificados o peso, a estatura e dosagem da concentração da hemoglobina do sangue capilar, com leitura imediata por hemoglobinômetro portátil. Foram feitas análises descritivas por meio de medidas de tendência central e dispersão, testes de proporções além de uma análise binária logística de múltiplas variáveis. Resultados - A prevalência de anemia nas mães foi de 9,6 por cento e nas crianças de 16,9 por cento. Para as mães, as variáveis analisadas que mostraram associação com anemia foram a idade, ter alguma doença, ter tido intercorrências obstétricas e ser atendida pela Estratégia de Saúde da Família, esta última aparecendo como fator de proteção para a mãe. Na análise multivariada apenas a Estratégia de Saúde da Família se manteve associada, enquanto as demais variáveis não mantiveram associação estatisticamente significante com a anemia. Paradoxalmente, a anemia materna não teve relação com a anemia do filho, bem como não houve correlação entre o nível de hemoglobina de mães anêmicas ou não anêmicas com o nível de hemoglobina de seus filhos. Conclusões - Apesar da anemia, nessa população de elevado Índice de Desenvolvimento Humano, ter prevalência baixa, segundo critério da Organização Mundial da Saúde, a mesma afetava uma em cada dez mães e uma em cada seis crianças. Isso evidencia que ainda há necessidade de atenção direcionada para esse agravo nas mulheres em idade reprodutiva e nas crianças com menos de cinco anos. Embora no grupo populacional haja semelhanças quanto às variáveis analisadas, é preciso um olhar atento às necessidades, principalmente em relação às crianças, com reforço na manutenção de ações intersetoriais entre saúde e educação, voltadas para a prevenção da anemia ferropriva


Introduction - The iron deficiency anemia, an important public health problem in both developing and developed countries, affects mainly under five-year-old children and women of reproductive age. Objective - to analyze the prevalence of anemia in women with children under 5 years-old enrolled in municipal day care centers in a municipality with a high Human Development Index. Methods - cross-sectional study. Sample consisting of 230 pairs of biological mothers aged 15-49 years and their under five-year-old children, who attended public day care centers in the city of Taubaté-SP. The data collection was performed through a questionnaire completed by those responsible for the child and a form applied to the mothers, to obtain information on socioeconomic and health factors of the woman and the child. The weight, height, and blood hemoglobin concentration of the capillary blood were verified from the mother and her respective son, with an immediate reading by the portable hemoglobinometer. Descriptive analyzes were made through measures of central tendency and dispersion proportions test, also a binary logistic analysis of multiple variables. Results - the prevalence of anemia in women was 9,6 per cent and in children 16.9 per cent. For women, the analyzed variables that showed an association with anemia were: age, being a carrier of disease, having had obstetric intercurrences and being attended by the Family Health Strategy, the latter appearing as a protection factor for the woman. In the multivariate analysis, only Family Health Strategy remained associated, while the other variables did not maintain a statistically significant association with anemia. Paradoxically, maternal anemia is not related to childhood anemia, and there was no correlation between the hemoglobin level of anemic and non-anemic mothers with their children\'s hemoglobin level. Conclusion - Although anemia in this high Human Development Index population was of low prevalence, according to World Health Organization criteria, it affected one in ten mothers and one in six children. This shows that there is still a need for targeted attention to this condition in women of reproductive age and in children under five years old. Although in the population group there are similarities to the analyzed variables, it is necessary to look closely at the needs, especially in relation to children, with a reinforcement in the maintenance of intersectoral actions between health and education aimed at the prevention of iron deficiency anemia
