ABSTRACT

OBJECTIVE@#Anemia is a common public health concern in patients with type 2 diabetes worldwide. This study aimed to identify the prevalence of anemia among patients with diabetes.@*METHODS@#Electronic databases, including PubMed, Scopus, Web of Sciences, and Google Scholar, were searched systematically for studies published between 2010 and 2021. After removing duplicates and inappropriate reports, the remaining manuscripts were reviewed and appraised using theNewcastle-Ottawa Scale (NOS) tool. A random-effects model was used to calculate the pooled estimates of the extracted data using Stata version 17. Heterogeneity of the studies was assessed using the Q statistic.@*RESULTS@#A total of 51 articles containing information on 26,485 patients with diabetes were included in this study. The articles were mainly from Asia (58.82%) and Africa (35.29%). The overall prevalence of anemia was 35.45% (95% CI: 30.30-40.76), with no evidence of heterogeneity by sex. Among the two continents with the highest number of studies, the prevalence of anemia in patients with diabetes was significantly higher in Asia [40.02; 95% CI: 32.72-47.54] compared to Africa [28.46; 95% CI: 21.90-35.50] ( P for heterogeneity = 0.029). Moreover, there has been an increasing trend in the prevalence of anemia in patients with diabetes over time, from [15.28; 95% CI: 9.83-22.21] in 2012 to [40.70; 95% CI: 10.21-75.93] in 2022.@*CONCLUSION@#Globally, approximately 4 in 10 patients with diabetes suffer from anemia. Therefore, routine anemia screening and control programs every 3 months might be useful in improving the quality of life of these patients.

ABSTRACT

Abstract Objective Pregnancy after bariatric surgery is a reality of the 21st century and therefore is essential that all obstetricians know how to manage it. The most prevalent nutritional deficiency is iron deficiency and, consequently, anemia. Although bariatric surgery and pregnancy are already risk factors for anemia, we evaluated in our study if there were any other risk factors and actions to improve hemoglobin levels in this population. Methods We performed a retrospective cohort study, and performed frequency measurements and analyzes of odds ratio, X2 and Fisher exact test to evaluate the risk factors. Results We evaluated 44 pregnancies after bariatric surgery, with an incidence of anemia of 62%, and the only identifiable risk factor for anemia was being black. As for the treatment, the iron salt used for oral supplementation did not associate with anemia risk, and in 27% of the patients, the adjustment of the oral dosage was enough for improvement in hemoglobin levels, but in 36% supplementation with intravenous iron was necessary. Conclusion Being black is a risk factor for anemia. The type of iron salt does not correlate with the incidence of anemia, and for the treatment and improvement of iron dosages, it seems an effective increase in iron intake.


Resumo Objetivo A gestação após cirurgia bariátrica é uma realidade do século XXI e, portanto, é de suma importância que os obstetras saibam conduzir o pré-natal dessas gestantes. A deficiência nutricional mais prevalente nessa população é a deficiência de ferro, que tem como consequência a anemia. Apesar da própria gestação e da cirurgia serem fatores de risco para anemia ferropriva, realizamos um estudo para avaliar se existem outros fatores que são de risco e quais condutas podem melhorar os níveis de hemoglobina nessa população. Métodos Trata-se de um estudo de coorte retrospectiva, e foram realizadas medidas de frequência e análise odds ratio, X2, e teste de exato de Fisher para a avaliação dos fatores de risco. Resultados Foram avaliadas 44 gestações após cirurgia bariátrica com incidência de anemia de 62%, sendo que o único fator de risco identificado foi a etnia preta. O sal de ferro utilizado na reposição não se associou com o risco de anemia. Em somente 27% das gestantes o ajuste da dose oral de ferro foi suficiente para corrigir a anemia, enquanto em 36% foi necessária a suplementação com ferro endovenoso. Conclusão Ser de etnia preta foi fator de risco para anemia após cirurgia bariátrica e o tipo de sal de ferro para suplementação não se correlacionou com a incidência de anemia. Para o tratamento da anemia, somente o ajuste da dose da medicação parece ser suficiente para a resolução desta.

ABSTRACT

Objective: To investigate the etiology, complications, and prognostic factors of stage 5 chronic kidney disease (CKD5) in children. Methods: A case series study was conducted to retrospectively analyze the general situation, clinical manifestations, laboratory tests, genetic testing, and follow-up data (until October 2022) of 174 children with CKD5 who were diagnosed and hospitalized at the Children's Hospital of Chongqing Medical University from April 2012 to April 2021. The characteristics of complications in the children were compared based on age, gender, and etiology. Based on the presence or absence of left ventricular hypertrophy (LVH), patients were divided into LVH group and non LVH group for analyzing the influencing factors of cardiovascular disease. Patients were also divided into death group and survival group, peritoneal dialysis group and hemodialysis group based on the follow-up data for analyzing the prognostic factors. The chi-square test, independent sample t-test, Fisher exact probability test, Mann-Whitney U test and Kruskal Wallis test were used to analyze data among different groups. Multivariate Logistic regression analysis was used to identify the prognostic factors. Results: A total of 174 children with CKD5 were enrolled in the study (96 boys and 78 girls), aged 11.2 (8.2, 13.0) years. Congenital kidney and urinary tract malformations (CAKUT) were the most common causes of the CKD5 (84 cases, 48.3%), followed by glomerular diseases (83 cases, 47.7%), and among which 28 cases (16.1%) were hereditary glomerular diseases. The common complications of CKD5 included anemia (98.2%, 165/168), mineral and bone disorder in chronic kidney disease (CKD-MBD) (97.7%, 170/174), lipid metabolism disorders (87.5%, 63/72), hypertension (81.4%, 127/156) and LVH (57.6%,57/99). The incidences of hypertension in primary glomerular disease were higher than that in CAKUT(93.8%(30/32) vs.73.7%(56/76),χ2=5.59,P<0.05). The incidences of hypertension in secondary glomerular disease were higher than that in CAKUT and that in hereditary kidney disease (100.0%(20/20) vs. 73.7%(56/76), 68.2%(15/22), both P<0.05). The incidence of hypocalcemia in CAKUT, primary glomerular disease, and hereditary kidney disease was higher than that in secondary glomerular disease (82.1%(69/84), 88.2%(30/34), 89.3%(25/28) vs. 47.6%(10/21), χ2=10.21, 10.75, 10.80, all P=0.001); the incidence of secondary hyperparathyroidism in women was higher than that in men (80.0%(64/80) vs. 95.0%(57/60), χ2=6.58, P=0.010). The incidence of LVH in children aged 6-<12 was higher than that in children aged 12-18 (73.5%(25/34) vs. 43.1%(22/51), χ2=7.62, P=0.006). Among 113 follow-up children, the mortality rate was 39.8% (45/113). Compared to the survival group, the children in the death group had lower hemoglobin, higher blood pressure, lower albumin, lower alkaline phosphatase and higher left ventricular mass index ((67±19) vs. (75±20) g/L, 142 (126, 154) vs. 128(113, 145) mmHg(1 mmHg=0.133 kPa), (91±21) vs. (82±22) mmHg, 32 (26, 41) vs. 40 (31, 43) g/L, 151 (82, 214) vs. 215 (129, 37) U/L, 48 (38, 66) vs. 38(32, 50) g/m2.7,t=2.03, Z=2.89, t=2.70, Z=2.49, 2.79, 2.29,all P<0.05), but no independent risk factors were identified (all P>0.05). The peritoneal dialysis group had better alleviation for anemia, low calcium, and high phosphorus than the hemodialysis group ((87±22) vs. (72±16) g/L, (1.9±0.5) vs. (1.7±0.4) mmol/L, (2.2±0.7) vs. (2.8±0.9) mmol/L, t=2.92, 2.29, 2.82, all P<0.05), and the survival rate of the peritoneal dialysis group was significantly higher than that of the hemodialysis group (77.8% (28/36) vs. 48.4% (30/62), χ2=8.14, P=0.004). Conclusions: CAKUT is the most common etiology in children with CKD 5, and anemia is the most common complication. The incidence of complications in children with CKD 5 varies with age, gender and etiology. Anemia, hypertension, hypoalbuminemia, reduced alkaline phosphatase and elevated LVMI may be the prognostic factors in children with CKD5. Peritoneal dialysis may be more beneficial for improving the long-term survival rate.

ABSTRACT

Abstract Introduction: Anemia and blood transfusion are risk factors for morbidity/mortality in patients undergoing cardiac surgery with cardiopulmonary bypass (CPB). The objective of this study is to analyze the association of blood transfusion with morbidity/mortality in patients undergoing coronary artery bypass grafting (CABG) under CPB in the state of São Paulo, Brazil. Methods: This is a retrospective analysis using the State of São Paulo Registry of Cardiovascular Surgery from November 2013 to August 2014. Blood transfusion was only considered during surgery or within six hours after surgery. Anemia was defined as hematocrit ≤ 37.5%. Patients < 18 years old were excluded. The sample was divided in four groups - Group I (851, no anemia), Group II (200, anemia without blood transfusion), Group III (181, no anemia and transfusion), and Group IV (258, anemia and transfusion). Results: A total of 1,490 patients were included; 639 (42.9%) were anemic and 439 (29.5%) underwent blood transfusion. Group II showed lower composite morbidity (odds ratio [OR] −0.05; confidence interval [CI] −0.27-0.17; P=0.81) than Group III (OR 0.41; CI 0.23-0.59; P=0.018) or Group IV (OR 0.54; CI 0.31-0.77; P=0.016). Group III was at greater risk of mortality (OR 0.73; CI 0.43-1.03; P=0.02) than Group II, which was exposed only to anemia (OR −0.13; CI −0.55-0.29; P=0.75), or Group IV (OR 0.29; CI −0.13-0.71; P=0.539). Conclusion: Anemia in patients undergoing CABG with CPB is bad, but blood transfusion can be worse, increasing at least 50% the risk for mortality and/or morbidity.

ABSTRACT

BACKGROUND@#Tuberculosis is a major public health problem caused by Mycobacterium tuberculosis, occurring predominantly in population with low socioeconomic status. It is the second most common cause of death from infectious diseases. Tuberculosis becomes a double burden among anemic patients. Anemia increases an individual's susceptibility to infectious diseases including tuberculosis by reducing the immunity level. Therefore, the purpose of this study was to determine whether anemia is a risk factor for tuberculosis.@*METHOD@#Relevant published articles were searched in electronic databases like PubMed, Google Scholar, EMBASE, and Cochrane Library using the following MeSH terms: risk factor, predictors, tuberculosis, TB, Anaemia, Anemia, hemoglobin, Hgb, and Hb. Articles written in the English, observational studies conducted on the incidence/prevalence of tuberculosis among anemic patients, or papers examined anemia as risk factors for tuberculosis were included. From those studies meeting eligibility criteria, the first author's name, publication year, study area, sample size and age of participants, study design, and effect measure of anemia for tuberculosis were extracted. The data were entered using Microsoft Excel and exported to Stata version 11 for analysis. The random-effects model was applied to estimate the pooled OR and HR, and 95% CI. The sources of heterogeneity were tested by Cochrane I-squared statistics. The publication bias was assessed using Egger's test statistics.@*RESULTS@#A total of 17 articles with a 215,294 study participants were included in the analysis. The odd of tuberculosis among anemic patients was 3.56 (95% CI 2.53-5.01) times higher than non-anemic patients. The cohort studies showed that the HR of tuberculosis was 2.01 (95% CI 1.70-2.37) times higher among anemic patients than non-anemic patients. The hazard of tuberculosis also increased with anemia severity (HR 1.37 (95% CI 0.92-2.05), 2.08 (95% CI 1.14-3.79), and 2.66 (95% CI 1.71-4.13) for mild, moderate, and severe anemia, respectively).@*CONCLUSION@#According to the current systematic review and meta-analysis, we can conclude that anemia was a risk factor for tuberculosis. Therefore, anemia screening, early diagnose, and treatment should be provoked in the community to reduce the burden of tuberculosis.

ABSTRACT

Abstract The aim of this study was to investigate the occurrence, type and severity of anemia at the time of diagnosis of oral cancer, and its potential association with the degree of tumor cell differentiation. This case-control study used 366 medical records of patients treated at two referral centers for oral cancer diagnosis, specifically: cases (n=70) with a histopathological diagnosis of oral squamous cell carcinoma (OSCC) of the oral cavity, and controls (n=296) with benign oral lesions. Sociodemographic, behavioral, and clinical variables of both groups, as well as complete blood count values, were analyzed by descriptive statistics and crude/adjusted logistic regression. Anemia was detected in 15.7% of the cases and 11.8% of the controls. The presence of anemia had an OR=1.64 (odds ratio) (95%CI 0.54-5.00) for OSCC, with no significantly statistical association. Normocytic anemia was the most prevalent form of anemia when oral cancer was diagnosed (91.4% of the controls and 72.7% of the cases), and moderate to severely low hemoglobin levels were associated with OSCC diagnosis (OR 6.49; 95%CI 1.18-35.24), albeit data on hematological examinations were missing.

ABSTRACT

A anemia no puerpério é bastante prevalente, estando principalmente relacionada à ocorrência de anemia não corrigida durante a gestação e às hemorragias agudas durante o parto. Essas situações aumentam significativamente a probabilidade de anemia grave no período pós-parto, gerando manifestações orgânicas e psicológicas que trazem prejuízo ao binômio materno-fetal. A forma grave da doença é caracterizada laboratorialmente por hemoglobina < 7 g/dL e suas manifestações clínicas variam na dependência de diversos fatores. O objetivo do tratamento é corrigir a hipóxia tecidual, revertendo as alterações adaptativas relacionadas à carência de oxigênio. Enquanto o tratamento agressivo de perdas volêmicas agudas diminui a morbimortalidade por esses eventos, políticas restritivas de transfusão sanguínea em pacientes hemodinamicamente estáveis mostram-se benéficas. Se não houver indicação de transfusão, a reposição de ferro atuará na correção das principais etiologias, pelas vias endovenosa ou oral, na dependência de disponibilidade, custo e tolerância individual aos medicamentos disponíveis.(AU)


Anemia is quite prevalent in puerperium; in this population, the disease is mainly related to the occurrence of uncorrected anemia during pregnancy and to acute bleeding during childbirth. These situations significantly increase the likelihood of severe anemia in the postpartum period, generating organic and psychological manifestations that cause damage to the maternal-fetal binomial. The severe form of anemia is characterized by hemoglobin < 7 g/dL and its clinical manifestations vary depending on several factors. The goal of treatment is to correct tissue hypoxia, reversing adaptive changes related to oxygen deficiency. While the aggressive treatment of acute blood losses decreases the morbidity and mortality of these events, restrictive blood transfusion policies in hemodynamically stable patients are beneficial. If there is no indication for transfusion, iron replacement will act to correct the main etiologies, through the intravenous or oral routes, depending on availability, cost and individual tolerance to the available drugs.(AU)

ABSTRACT

Este trabajo tiene como objetivo revisar las contribuciones de la biotecnología, en relación con el tratamiento, diagnóstico y la monitorización de la enfermedad renal crónica (ERC) y sus comorbilidades más frecuentes, especialmente la anemia. En relación con los tratamientos, enfocamos el desarrollo de productos biofarmacéuticos como los agentes estimulantes de la eritropoyesis (ESA), que fueron los primeros biofármacos utilizados para el tratamiento de la anemia asociada a la ERC; analizamos sus características y utilización actual después de varios años de experiencia clínica, así como también otras alternativas en desarrollo. Revisamos distintos tipos de bioterapias, la utilización de las células estromales mesenquimales de médula ósea (MSC) y tratamientos alternativos con modificaciones dietarias, que se basan en la asociación entre la microbiota intestinal de los pacientes renales crónicos y sus condiciones fisiopatológicas. Finalmente, en relación con el diagnóstico y monitorización, nos referimos al estudio y validación de biomarcadores diagnósticos, predictivos y terapéuticos que han permitido optimizar los resultados clínicos en este tipo de pacientes. (AU)


The aim of this work is to review the contributions of biotechnology, in relation to the treatment, diagnosis and monitoring of chronic kidney disease (CKD) and its most frequent comorbidities, especially anemia. Regarding the treatment, we focus on the development of biopharmaceutical products such as erythropoiesis stimulating agents (ESA), which were the first biopharmaceuticals used to treat anemia associated with chronic kidney disease (CKD). We analyzed their characteristics and their current use after several years of clinical experience, as well as other alternatives in development. We also review different types of biotherapies, the use of bone marrow mesenchymal stromal cells (MSC) and alternative treatments with dietary modifications, which are based on the association between the intestinal microbiota of chronic kidney patients and their pathophysiological conditions. Finally, in relation to diagnosis and monitoring, we refer to the study and validation of diagnostic, predictive and therapeutic biomarkers that have made clinical results possible to be optimized in this type of patient.

ABSTRACT

O HIV é o causador da AIDS, doença que representa um dos grandes problemas de saúde pública em todo o mundo. Apesar de avanços na terapia antirretroviral no sentido de aumentar a expectativa de vida dos indivíduos infectados, as alterações hematológicas, como a anemia, acompanham o curso clínico da doença. Essa condição, normalmente multifatorial, pode estar presente em qualquer fase da doença e afeta diretamente o prognóstico e a qualidade de vida do indivíduo infectado. Este artigo apresenta informações do surgimento do processo anêmico com base nas principais causas encontradas na literatura.


The human immunodeficiency virus is the cause of the acquired immunodeficiency syndrome, a disease that represents one of the major public health problems worldwide. In spite of advances in antiretroviral therapy that increase patients' life expectancy, hematological changes, such as anemia, follow the clinical course of the disease. This commonly multifactorial condition can be found in any phase of the disease and directly affects the prognosis and quality of life of patients. This article presents information on the emergence of the anemic process based on the main causes found in the literature.

ABSTRACT

OBJETIVO: Remarcar la importancia de hacer un adecuado diagnóstico diferencial de la anemia y trombocitopenia en la gestante, ya que en ocasiones enmascaran cuadros tan graves como la leucemia. Presentar un caso de leucemia mieloide aguda con una preeclampsia sobreañadida y describir el proceso diagnóstico y terapéutico llevado a cabo. CASO CLÍNICO: Secundigesta, 25 años, gestante de 37 semanas, con antecedentes de preeclampsia, derivada desde atención primaria por alteración analítica y malestar general. A su llegada a urgencias el cuadro clínico es compatible con un Síndrome de HELLP. Tras el estudio del mismo se llega a la certeza de que se trata de una preeclampsia asociada a una leucemia mieloide aguda que ha simulado los parámetros analíticos de un Síndrome de HELLP. CONCLUSIONES: Es importante el adecuado estudio etiológico de la anemia y trombocitopenia en la gestación. La leucemia exige al clínico un abordaje precoz y multidisciplinar tanto diagnóstico como terapéutico.


OBJECTIVE: To emphasize on the importance of performing a precise differential diagnosis of anaemia and thrombocytopenia during pregnancy, as they can be due to important diseases as leukemia. A case of acute myeloid leukemia associated with preeclampsia is reported, describing the complexity of the diagnostic and therapeutic process. CLINICAL CASE: 25-year-old woman, gravida 2, para 1 (preeclampsia), at 36 weeks of gestation was referred to the emergency department by her primary care physician due to severe disturbance on the blood tests and general discomfort. Initially, a HELLP syndrome was suspected. However, after going in depth in the case, the final diagnosis was preeclampsia associated to acute myeloid leukemia, simulating blood parameters in HELLP syndrome. CONCLUSIONS: It is essential to study deeply and carry out a complete differential diagnosis process of anaemia and thrombocytopenia during pregnancy. Leukemia requires an early multidisciplinary management both for diagnosis and treatment.

ABSTRACT

Objetivo: Comparar características sociodemográficas, comportamentais, condições de saúde e parâmetros laboratoriais entre idosos anêmicos e não anêmicos. Métodos: Estudo epidemiológico transversal realizado com 257 idosos. Para realizar as comparações utilizou-se o teste t para amostras independentes e o teste não paramétrico U de Mann-Whitney. Resultados: Encontrou-se maior proporção de anemia em idosos com idade acima de 80 anos (p=0,026), e maior proporção de dependência para atividades básicas (p=0,018) e instrumentais (p=0,010) da vida diária em idosos com anemia. Identificou-se diferença na distribuição da dosagem dos parâmetros laboratoriais, sendo as concentrações médias de ureia e creatinina maiores nos idosos anêmicos, e esses tiveram menores concentrações de glicemia, albumina, ALT/TGP, cálcio sérico e T3 total. Conclusão: A anemia não está relacionada exclusivamente ao processo de envelhecimento, mas sim resultado de múltiplos fatores como as condições sociodemográficas, de saúde, alimentares e de vida dos idosos


Objective: To compare sociodemographic, behavioral characteristics, health conditions and laboratory parameters among anemic and non - anemic elderly. Methods: Cross-sectional epidemiological study with 257 elderly subjects. To perform comparisons, the t-test for independent samples and the non-parametric Mann-Whitney U test were used. Results: There was a higher proportion of anemia in the elderly over 80 years (p = 0.026), and a higher proportion of dependence on basic activities (p = 0.018) and instrumental (p = 0.010) daily activities in elderly patients with anemia. Differences were observed in the distribution of laboratory parameters, with mean values of urea and creatinine being higher in anemic elderly, with lower concentrations of glycemia, albumin, ALT / TGP, serum calcium and total T3. Conclusion: Anemia is not exclusively related to the aging process, but is a result of multiple factors such as sociodemographic, health, food and life conditions of the elderly


Objetivo: Comparar características sociodemográficas, comportamentales, condiciones de salud y parámetros de laboratorio entre ancianos anémicos y no anémicos. Metodo: Estudio epidemiológico transversal realizado con 257 ancianos. Para realizar las comparaciones se utilizó la prueba t para muestras independientes y la prueba no paramétrica U de Mann-Whitney. Resultados: Se encontró mayor proporción de anemia en ancianos con edad superior a 80 años (p = 0,026), y mayor proporción de dependencia para actividades básicas (p = 0,018) e instrumentales (p = 0,010) de la vida diaria en ancianos con anemia. Se identificó diferencia en la distribución de la dosificación de los parámetros de laboratorio, siendo las concentraciones medias de urea y creatinina mayores en los ancianos anêmicos. Conclusión: La anemia no está relacionada exclusivamente con el proceso de envejecimiento, sino el resultado de múltiples factores como las condiciones sociodemográficas, de salud, alimentos y de vida de los ancianos

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

RESUMEN INTRODUCCIÓN: La anemia fetal es una importante causa de morbilidad y mortalidad perinatal. En la actualidad la principal herramienta terapéutica es la transfusión fetal intrauterina, permitiendo una mejoría en el pronóstico y sobrevida en fetos con anemia severa. El objetivo de este estudio fue reportar los resultados obtenidos en el Centro de Referencia Perinatal Oriente (CERPO). MÉTODO: Se realizó un análisis descriptivo retrospectivo de los casos de anemia fetal que requirieron transfusión intrauterina en CERPO entre los años 2003-2019. RESULTADOS: Se incluyeron 17 embarazos, con un total de 27 procedimientos. La sobrevida perinatal fue de 82%, con un 18% de mortalidad perinatal. Se reporta una tasa de mortalidad de 3,7% asociado al procedimiento. CONCLUSIÓN: Los resultados observados son similares a lo publicado, con una tasa de complicaciones similar a lo reportado en la literatura internacional y nacional.

ABSTRACT

Resumo O objetivo deste artigo é avaliar a associação entre a anemia e algumas atividades de vida diária associadas à alimentação e o relato de dificuldade de mastigação e deglutição. Estudo transversal, que analisou 1.256 indivíduos de 60 anos ou mais, que fizeram parte da terceira coleta do Estudo SABE (Saúde, Bem-estar e Envelhecimento). Considerou-se anêmicos homens com hemoglobina sanguínea ≤ 13g/dL e mulheres com valores ≤ 12g/dL. Houve prevalência de anemia maior nos indivíduos que relataram redução no consumo alimentar devido a queixas de mastigação e deglutição, naqueles com dificuldade de mastigação e nos que relataram dificuldade em alimentar-se devido queixas de mastigação e deglutição. A prevalência também foi maior nos indivíduos com dificuldade de alimentar-se sozinho e de fazer compras de alimentos. Nas análises, a presença de uma queixa de mastigação e deglutição foi associada à chance de anemia quase 2 vezes maior que aqueles indivíduos sem queixas, e a presença de 2 ou 3 queixas de mastigação e deglutição foi associada à chance de 2,7. Os idosos com dificuldades de deglutição e mastigação apresentaram maior prevalência de anemia, mesmo após ajuste de outros fatores associados, com efeito dose-resposta, evidenciando a importância de um trabalho multidisciplinar com o idoso.


Abstract Aim: To evaluate the association between anemia and some activities of daily living associated with feeding and the difficulty in chewing and swallowing. Methods: Cross-sectional study, which examined 1256 individuals, aged 60 or older who were part of the third collection of the SABE Study (Health, Well-Being and Aging). We classified as anemic men with blood haemoglobin ≤ 13 g/dL and women with values ≤ 12 g/dL. Results: Prevalence of anemia was higher in individuals who reported reduction in food consumption due to chewing and swallowing complaints, in individuals with difficulty to chew and in individuals who reported difficulty to feed themselves due to chewing and swallowing complaints. Anemia was also more prevalent in those with difficulty to feed themselves and to shop for food. In the analyses, the presence of chewing and swallowing complaints was associated with a chance of anemia almost 2 times greater than for individuals without complaints, and the presence of 2 or 3 chewing and swallowing complaints was associated with a 2.7 chance of anemia. Conclusion: The presence of difficulties in chewing and swallowing were associated with higher prevalence of anemia, even after adjustment for other factors, with a dose-response effect, indicating the importance of a multidisciplinary work with older adults.

ABSTRACT

RESUMEN El síndrome de Van Wyk-Grumbach se caracteriza por hipotiroidismo primario de larga duración asociado a pubertad precoz. Se presenta una paciente de 7 años, mestiza, que acude por sangrado vaginal, acompañado de hiperpigmentación de las areolas sin galactorrea, abdomen globuloso, mixedema, hirsutismo, baja talla, astenia y retraso escolar. La química sanguínea mostró anemia, hipercolesterolemia y hipertransaminasemia; los estudios de imágenes constataron derrame pericárdico, retraso marcado de la edad ósea, incremento de las dimensiones de la silla turca y gran quiste del ovario con aparente criterio quirúrgico. Los estudios hormonales confirmaron la sospecha de hipotiroidismo primario asociado a hiperprolactinemia. El tratamiento sustitutivo con levotiroxina sódica revirtió los signos y síntomas de pubertad precoz, lo que evitó la cirugía del quiste de ovario; la recuperación en el ambiente escolar y social fue indiscutible. Reconocer esta entidad evita tratamientos absolutamente contraindicados, como la extirpación de los quistes o el tratamiento quirúrgico de la hiperplasia hipofisaria(AU)


ABSTRACT Van Wyk-Grumbach syndrome is characterized by long-lasting primary hypothyroidism associated with precocious puberty. A case of a 7-year-old female mestizo patient is reported. She came to consultation for vaginal bleeding, accompanied by hyperpigmentation of the areolas without galactorrhea, globular abdomen, myxedema, hirsutism, short stature, asthenia and school delay. Blood chemistry showed anemia, hypercholesterolemia and hypertransaminasemia. Imaging studies showed pericardial effusion, marked delay in bone age, increased dimensions of Turkish chair and large ovarian cyst with apparent surgical criteria. Hormonal studies confirmed the suspicion of primary hypothyroidism associated with hyperprolactinemia. Substitute treatment with levothyroxine sodium reversed the signs and symptoms of precocious puberty, which prevented ovarian cyst surgery; the recovery in the school and social environment was certain. Recognizing this entity avoids absolutely contraindicated treatments, such as the removal of cysts or the surgical treatment of pituitary hyperplasia(AU)

ABSTRACT

Resumen Introducción. La malaria (o paludismo) durante la gestación impacta negativamente la salud de la madre y del neonato, con alto riesgo de complicaciones clínicas y mortalidad. En las regiones de alta endemia se han caracterizado, especialmente, la anemia materna y el bajo peso al nacer, pero es poco conocido el espectro clínico en las zonas de baja endemia. Objetivo. Caracterizar clínica y epidemiológicamente los episodios de malaria en mujeres gestantes hospitalizadas en el departamento de Antioquia entre el 2010 y el 2014. Materiales y métodos. Se hizo un estudio descriptivo, transversal y retrospectivo, con historias clínicas de mujeres gestantes con malaria por Plasmodium falciparum y P. vivax. Se utilizaron los criterios diagnósticos de malaria complicada de la Organización Mundial de la Salud (OMS) y de la Guía para la atención clínica integral del paciente con malaria vigente en Colombia. Resultados. Se analizaron 111 casos; el 13,5 % se clasificó como complicación grave según los criterios de la OMS, porcentaje que ascendió a 23,4 % según los criterios de la guía colombiana. Las complicaciones detectadas fueron disfunción hepática, anemia, acidosis y trombocitopenia grave. No se observó diferencia en la frecuencia de las complicaciones según la especie de plasmodio. El 39,4 % de los casos presentó signos generales de peligro; la palidez y la ictericia fueron los más frecuentes. El 40,5 % presentó signos de peligro para la gestación como la cefalea persistente, el dolor abdominal y el sangrado vaginal. Conclusiones. La malaria grave se presenta con gran frecuencia en las mujeres gestantes, sin diferencia según la especie de plasmodio, y se manifiesta con signos de peligro precozmente reconocibles. Se encontró un subregistro hospitalario del 88 % de los casos graves y falta de exámenes de laboratorio para un diagnóstico más completo. Se requiere un protocolo para el diagnóstico clínico de las mujeres gestantes con malaria.


Abstract Introduction: Malaria during pregnancy has a negative impact on maternal-neonatal health, with a high risk of clinic complications and mortality. High endemic areas are specially characterized by maternal anaemia and low birth weight. The clinical spectrum is little known in low endemic areas. Objective: To clinically and epidemiologically characterize malaria episodes in hospitalized pregnant women in the Department of Antioquia (Colombia) in the period 2010-2014. Materials and methods: Retrospective, cross-sectional, descriptive study with medical records of pregnant women with P. falciparum and P. vivax malaria. The WHO severe malaria diagnostic criteria and the Colombian Guía para la atención clínica integral del paciente con malaria (guidelines for comprehensive malaria treatment) were used. Results: We analyzed 111 cases, out of which 13.5% were classified as severe malaria according to the WHO criteria. Following the Colombian Guidelines, the proportion increased to 23.4%. Identified complications included hepatic dysfunction, anaemia, acidosis, and severe thrombocytopenia. No difference in the frequency of complications by Plasmodium species was observed; 39.4% of the cases presented general danger signs, pallor and jaundice being the most frequent; 40.5% showed danger signs for pregnancy, such as persistent headache, abdominal pain, and vaginal bleeding. Conclusions: Severe malaria is a highly frequent event in pregnant women, without differences by Plasmodium species. It shows early recognizable dangers signs. Hospital under-reporting was identified in 88% of severe cases as well as a lack of laboratory tests for a more comprehensive diagnosis. A protocol for the clinical diagnosis of pregnant women with malaria is required.

ABSTRACT

RESUMO Objetivo: Avaliar a prevalência e os fatores associados à anemia em lactentes assistidos por Unidades de Saúde de Vitória da Conquista, Bahia. Métodos: Estudo transversal com uma amostra representativa de 366 crianças de 6 a 23 meses. Realizou-se aplicação de questionário ao cuidador, avaliação antropométrica e dosagem de hemoglobina das crianças. As associações foram identificadas por meio da regressão de Poisson com variâncias robustas com seleção hierárquica das variáveis independentes. Resultados: A prevalência de anemia foi de 26,8%, e os fatores associados foram: renda familiar igual ou inferior a um salário mínimo (RP: 1,50; IC95% 1,03-2,18), número de moradores no domicílio superior a cinco (RP: 1,50; IC95% 1,07-2,11), utilização de água não filtrada (RP: 1,68; IC95% 1,11 -2,56), número de filhos maior que três (RP: 1,64; IC95% 1,01-2,68), consumo de carne e/ou vísceras menor que uma vez por semana (RP: 1,78; IC95% 1,24-2,58) e idade de 6 a 11 meses (RP: 1,75; IC95% 1,20-2,55). Conclusões: A anemia nos lactentes avaliados é um moderado problema de saúde pública, a qual está associada a fatores socioeconômicos, demográficos e dietéticos. Dessa forma, medidas são necessárias para sua prevenção.


ABSTRACT Objective: To evaluate the prevalence of anemia and the associated factors in infants assisted in health units of Vitória da Conquista, Bahia, Northeast Brazil. Methods: Cross-sectional study with a representative sample of 366 children aged 6 to 23 months. A questionnaire was applied to the caregiver, and the children's anthropometric measurements and hemoglobin levels were collected. The associations were identified by Poisson regression with robust variances based on a hierarchical analysis model. Results: The prevalence of anemia was 26.8%, and the associated factors were: family income equal to or lower than one minimum wage (PR: 1.50; 95%CI 1.03-2.18), number of household members higher than five (PR: 1.50; 95%CI 1.07-2.11), use of unfiltered water (PR: 1.68; 95%CI 1.11-2.56), number of offspring higher than three (PR: 1.64; 95%CI 1.01-2.68), consumption of meat and/or viscera less than once/week (PR: 1.78; 95%CI 1.24-2.58) and age 6-11 months (PR: 1.75; 95%CI 1.20-2.55). Conclusions: Anemia in the infants assessed is a moderate public health problem, which is associated with socioeconomic, demographic, and dietary factors; thus, measures are necessary for its prevention.

ABSTRACT

RESUMEN Objetivos. Determinar la frecuencia y el valor pronóstico de la anemia en pacientes con cáncer atendidos en el Instituto Nacional de Enfermedades Neoplásicas (INEN) entre enero y abril del 2010. Materiales y métodos. Se consideró anemia en varones cuando la hemoglobina fue <13 g/dL, y en mujeres cuando fue <12 g/dL. Para determinar asociaciones se usó la prueba Chi-cuadrado. Para el análisis de las curvas de sobrevida se usó el estimador de Kaplan-Meier y log rank test. Resultados. 772 pacientes fueron incluidos; 584 (75,7%) tuvieron tumores sólidos y 188 (24,3%) neoplasias hematológicas. Se diagnóstico anemia en 359 (46,5%) pacientes, en 124 (66,0%) neoplasias hematológicas, y en 235 (40,2%) neoplasias sólidas. Las neoplasias hematológicas con mayor frecuencia de anemia fueron la leucemia mieloide crónica, las leucemias agudas, y el mieloma múltiple (100%, 92,5% y 60%; respectivamente) y en el grupo de neoplasias sólidas fueron los cánceres de origen: gastrointestinal, ginecológico, y urológico (62%, 52,1% y 45%; respectivamente). Recibieron transfusiones 204 pacientes (26,4%). En 762 pacientes se encontró una diferencia en la sobrevida global entre los grupos sin y con presencia de anemia, estimándose a los cinco años en 62% y 47% respectivamente (p<0,001), además se encontraron diferencias en la sobrevida global para el subgrupo de tumores sólidos (p=0,002) y neoplasias hematológicas (p=0,007). Conclusiones. La anemia es frecuente en pacientes con cáncer y su presencia determina un factor pronóstico independiente en la sobrevida global.


ABSTRACT Objective. To determine the frequency and prognostic value of anemia in cancer patients receiving care at the National Institute of Neoplastic Diseases (Instituto Nacional de Enfermedades Neoplásicas - INEN) between January and April of 2010. Materials and Methods. Anemia was considered for men with hemoglobin levels at <13 g/dL; and for women, at <12 g/dL. Associations between qualitative features were assessed with a Chi-square test. Kaplan-Meier estimator was used for the analysis of the survival curves, and differences between the curves were performed with the log-rank test. Results. 772 patients were included; 584 (75.7%) had solid tumors and 188 (24.3%) had hematologic malignancies. Anemia was diagnosed in 359 patients (46.5%); hematologic malignancies in 127 patients (67.6%); and solid neoplasms in 235 (40.2%). Hematologic malignancies with the highest frequency of anemia were chronic myeloid leukemia, acute leukemias, and multiple myeloma (100%, 92.5% and 60%, respectively); and were cancer of gastrointestinal, gynecological, and urological origin were in the group of solid neoplasms (62%, 52.1% and 45%, respectively). Two hundred and four (204) patients (26.4%) were transfused. In 762 patients, a significant difference in overall survival was found between groups with and without anemia, estimated at 5 years in 62% and 47% respectively (p <0.001). In the solid tumor subgroup (p = 0.002), and the hematological malignancies subgroup (p = 0.007), such association was also found. Conclusions. Anemia is common in cancer patients, and its presence determines an independent prognostic factor in overall survival.
