Relación entre niveles de vitamina D y perfil lipídico en embarazadas de alto riesgo / Relationship between level of vitamin D and lipid profile in high risk pregnant women

En la Argentina, las embarazadas presentan alta prevalencia (80%) de hipovitaminosis D y de sobrepeso u obesidad (27,4%). Ambas condiciones pueden aumentar la morbimortalidad materno-fetal. Bajos niveles de vitamina D se han relacionado con aumento del colesterol total, LDL, triglicéridos (Tg) y descenso de HDL. Objetivo: evaluar los niveles de 25-hidroxivitamina D (25OHD) y su relación con el perfil lipídico en pacientes embarazadas de alto riesgo. Materiales y métodos: estudio de corte transversal entre septiembre de 2016 y abril de 2017. Se excluyeron pacientes que recibieron suplementos de vitamina D, con disfunción tiroidea no compensada, malabsorción, insuficiencia cardíaca, renal o hepática y dislipidemia familiar. Niveles circulantes de 25OHD < 30 ng/ml se consideraron hipovitaminosis. Resultados: se evaluaron 86 embarazadas de 29,3 ± 7,1 años durante la semana 28 ± 6,5. El IMC pregestacional fue 28,3 ± 6,5 kg/m2 y la ganancia de peso 7 ± 4,3 kg. Perfil lipídico: colesterol total 240 ± 54 mg/dl; LDL 156 ± 54 mg/dl; HDL 66 ± 15 mg/dl; Tg 204 ± 80 mg/dl. La media de 25OHD fue de 23,8 ± 9 ng/ml, con una prevalencia de hipovitaminosis D de 77,9 %. Las pacientes con hipovitaminosis D presentaron mayores valores de colesterol total y LDL (p < 0,05), con tendencia no significativa a presentar mayores valores de Tg. Conclusión: en embarazadas de alto riesgo se observó una alta prevalencia de hipovitaminosis D, asociada con mayores concentraciones de colesterol total y LDL. (AU)

In Argentina, pregnant women have a high prevalence (80 %) of hypovitaminosis D and verweight/obesity (27.4%), conditions that can increase maternal-fetal morbidity and mortality. Low levels of 25-hydroxyvitamin D (25OHD) have been linked to an increase in total cholesterol, LDL cholesterol, triglycerides (TG) and a decrease in HDL cholesterol. Objective: to evaluate the levels of vitamin D and its relationship with the lipid profile in high risk pregnant patients. Materials and methods: cross-sectional study between September 2016 and April 2017. Patients who received vitamin D supplements or had non-compensated thyroid dysfunction, malabsorption, heart failure, renal or hepatic failure, or familial dyslipidemia were excluded. Hypovitaminosis D was defined as a circulating level of 25OHD < 30 ng/ml. Results: We assessed 86 women of 29.3 ± 7.1 years during pregnancy week 28 ± 6.5. Pre-gestational BMI was 28.3 ± 6.5 kg/m2. Their weight gain was 7 ± 4.3 kg. Lipid profile: total cholesterol 240 ± 54 mg/dl; LDL cholesterol 156 ± 54 mg/dl; HDL cholesterol 66 ± 15 mg/dL; TG 204 ± 80 mg/dl. The mean 25OHD level was 23.8 ± 9 ng/ml, with a 77.9 % prevalence of hypovitaminosis D. Patients with hypovitaminosis D had higher values of total cholesterol and LDL cholesterol (p<0.05), and a non-significant trend toward higher triglyceridemia. Conclusion: A high prevalence of hypovitaminosis D, associated with high total and LDL cholesterol was found in high risk pregnant women. (AU)

Anemia em gestantes atendidas em Unidades Básicas de Saúde da região administrativa do Butantã, município de São Paulo, em 2006 e 2008 / Anemia in pregnant women assisted at Health Basic Units of Butantã administrative region, city of São Paulo, in 2006 and 2008

O presente estudo verificou a prevalência de anemia em gestantes atendidas em 13 Unidades Básicas de Saúde da Supervisão Técnica de Saúde do Butantã-SP. Trata-se de estudo transversal com dados secundários de prontuários de 772 gestantes, à primeira consulta do pré-natal, nos anos de 2006 (387) e de 2008 (385). Foram incluídas no estudo as gestantes cujos prontuários apresentavam os seguintes dados: idade, peso, trimestre gestacional, concentração de hemoglobina e RDW na primeira consulta de pré-natal e ausência de doenças crônicas. De acordo com o estado nutricional pré-gestacional, observaram-se maiores prevalências de eutrofia (61 %), seguidas por 21,5 % de sobrepeso e por 10,8 % de obesidade. A prevalência de anemia foi de 10,0 % em 2006 e de 8,8 % em 2008, sem diferença estatisticamente significativa entre os valores (p > 0,05). Como esperado, a prevalência aumentou com a evolução da gestação. Em 2006 as médias de Hb diminuíram de 12,6 (1,0) g/dL no I trimestre para 12,2 (1,1) g/dL no II trimestre e 11,5 (1,0) g/dL no III trimestre gestacional. Os valores foram similares no ano de 2008. A distribuição das médias de Hb e RDW nos dois anos não mostrou diferenças estatísticas significativas (p > 0,05). As gestantes que estavam no II trimestre apresentaram risco de anisocitose maior em 41%, quando comparadas às que fizeram sua primeira consulta no primeiro trimestre. Esse nível de prevalência de anemia é classificado como associado a um risco populacional leve, segundo a Organização Mundial de Saúde

The present study verified the prevalence of anemia among pregnant women assisted in 13 Health Basic Units of the Health Technical Supervision in Butantã-SP. This is a cross-sectional study with secondary data from medical charts of 772 pregnant women, upon the first prenatal visit to the doctor, in 2006 (387 women) and 2008 (385 women). The study included pregnant women whose medical charts contained the following data: age, weight, gestational quarter, hemoglobin concentration and RDW upon the first prenatal visit and lack of chronic diseases. According to the gestational nutritional status, the largest prevalence of eutrophic women (61 %) was observed, followed by 21.5 % overweight and 10.8 % obese. The prevalence of anemia was 10.0 % in 2006 and 8.8 % in 2008, with no statistically significant difference between the values (p > 0.05). As expected, the prevalence increased with the evolution of gestation. In 2006, the mean Hb values decreased from 12.6 (1.0) g/dL in the first quarter to 12.2 (1.1) g/dL in the second quarter and 11.5 (1.0) g/dL in the third quarter of pregnancy. The values were similar in 2008. The mean Hb distribution and RDW in both years showed no statistically significant differences (p > 0.05). The pregnant women who were in the second quarter of pregnancy showed a 41 % larger risk of anisocytosis when compared to the ones who attended the first medical visit in the first quarter of pregnancy. This level of prevalence for anemia is classified as associated to a slight risk for the population, according to the World Health Organization
