FUNDAMENTO: Infusão de intralipid e heparina resulta em aumento da pressão arterial e também em anormalidades autonômicas em indivíduos normais e hipertensos. OBJETIVO: Avaliar a sensibilidade a insulina e o impacto da infusão de intralipid e de heparina (ILH) sobre a resposta hemodinâmica, metabólica e autonômica em pacientes com a forma indeterminada da doença de Chagas. MÉTODOS: Doze pacientes com a forma indeterminada da doença de Chagas e 12 voluntários saudáveis foram avaliados. RESULTADOS: A pressão arterial basal e a frequência cardíaca foram semelhantes nos dois grupos. Os níveis plasmáticos de noradrenalina encontravam-se ligeiramente aumentados no grupo de pacientes chagásicos. Após o Teste de Tolerância a Insulina (TTI), houve um declínio significativo na glicose dos dois grupos. A Infusão de ILH resultou em aumento da pressão arterial em ambos os grupos, mas não houve nenhuma mudança significativa na noradrenalina plasmática. O componente de Baixa Frequência (BF) mostrou-se semelhante e aumentou de forma semelhante em ambos os grupos. O componente de Alta Frequência (AF) apresentou-se menor no grupo chagásico. CONCLUSÃO: Pacientes com forma indeterminada da doença de Chagas apresentaram aumento da atividade simpática no momento basal e uma resposta inadequada à insulina. Eles também tiveram um menor componente de alta frequência e sensibilidade barorreflexa prejudicada no momento basal e durante a infusão de intralipid e heparina.FUNDAMENTO: La Infusión de intralipid® y de heparina trae como resultado un aumento de la presión arterial y también de las anormalidades autonómicas en los individuos normales e hipertensos. OBJETIVO: Evaluar la sensibilidad a la insulina y el impacto de la infusión de intralipid® y de heparina (ILH) sobre la respuesta hemodinámica, metabólica y autonómica en pacientes con la forma indefinida de la Enfermedad de Chagas. MÉTODOS: Fueron evaluados doce pacientes con la forma indefinida de la Enfermedad de Chagas y 12 voluntarios sanos. RESULTADOS: La presión arterial basal y la frecuencia cardíaca fueron similares en los dos grupos. Los niveles plasmáticos de noradrenalina estaban ligeramente más elevados en el grupo de pacientes chagásicos. Después del Test de Tolerancia a la Insulina (TTI), se produjo una ostensible disminución en la glucosa de los dos grupos. La Infusión de ILH trajo como consecuencia el aumento de la presión arterial en ambos grupos, pero no hubo ningún cambio significativo en la noradrenalina plasmática. El componente de Baja Frecuencia (BF), fue similar y aumentó de forma parecida en ambos grupos. El componente de Alta Frecuencia (AF) se presentó con un menor nivel en el grupo chagásico. CONCLUSIONES: Los pacientes con una forma indeterminada de la Enfermedad de Chagas, presentaron un aumento en la actividad simpática al momento basal y una respuesta inadecuada a la insulina. También tuvieron un menor componente de alta frecuencia y de sensibilidad barorrefleja, que fue perjudicado en el momento basal y durante la infusión de intralipid® y heparina.BACKGROUND: Intralipid and heparin infusion results in increased blood pressure and autonomic abnormalities in normal and hypertensive individuals. OBJECTIVE: To evaluate insulin sensitivity and the impact of Intralipid and heparin (ILH) infusion on hemodynamic, metabolic, and autonomic response in patients with the indeterminate form of Chagas' disease. METHODS: Twelve patients with the indeterminate form of Chagas' disease and 12 healthy volunteers were evaluated. RESULTS: Baseline blood pressure and heart rate were similar in both groups. Plasma noradrenaline levels were slightly increased in the Chagas' group. After insulin tolerance testing (ITT), a significant decline was noted in glucose in both groups. ILH infusion resulted in increased blood pressure in both groups, but there was no significant change in plasma noradrenaline. The low-frequency component (LF) was similar and similarly increased in both groups. The high-frequency component (HF) was lower in the Chagas' group. CONCLUSION: Patients with the indeterminate form of Chagas' disease had increased sympathetic activity at baseline and impaired response to insulin. They also had a lower high-frequency component and impaired baroreflex sensitivity at baseline and during Intralipid and heparin infusion.

FUNDAMENTO: Recentemente, uma associação de diferentes fatores de risco foi descrita como a síndrome metabólica. Diferentes definições estão sendo utilizadas para a mesma síndrome. Independente do nome ou da classificação, estabeleceu-se que um agrupamento de fatores de risco cardiovasculares incluindo sobrepeso/obesidade, aumento da pressão arterial e anormalidade lipídicas e glicêmicas está associado com aumento do risco de aterosclerose em adultos. OBJETIVO: O objetivo desse estudo foi correlacionar os percentis do índice de massa corporal com a pressão arterial (PA), índice de resistência à insulina (HOMA-ir) e perfis lipídicos em crianças e adolescentes, os quais caracterizam um perfil pró-aterosclerótico. MÉTODOS: Agrupamentos de fatores de risco cardiovasculares foram avaliados em 118 crianças e adolescentes, divididos de acordo com os quartis do percentil de índice de massa corporal (PIMC): Q1 (n=23) com PIMC 93%. Estatisticamente, diferenças significantes não foram observadas para idade (F=2,1; p=0,10); sexo (teste Qui-quadrado=3,0; p=0,38), e etnia (teste do Qui-quadrado = 4,7; p=0,20) entre diferentes quartis.

Different definitions are being used for the same syndrome. Regardless of the name or classification, it has been well established that a cardiovascular cluster including overweight/obesity, increased blood pressure, and lipid and glucose abnormalities are associated with an increased risk of atherosclerosis in adults. OBJECTIVE: The aim of this study was to correlate body mass index percentiles with blood pressure, insulin resistance index, and lipid profiles in children and adolescents, which characterize a proatherosclerotic profile. METHODS: Cardiovascular risk factor clusters were evaluated in 118 children and adolescents divided according to body mass index percentile (BMIP) quartiles: Q1 (n=23) with BMIP 93%. Statistically significant differences were not observed for age (F=2.1; p=0.10); sex (chi-square test=3.0; p=0.38), and ethnicity (chi-square test=4.7; p=0.20) between different quartiles. RESULTS: A statistically significant difference was observed for systolic BP (F=15.4; p

We report the case of a 72-year-old female with pure autonomic failure, a rare entity, whose diagnosis of autonomic dysfunction was determined with a series of complementary tests. For approximately 2 years, the patient has been experiencing dizziness and a tendency to fall, a significant weight loss, generalized weakness, dysphagia, intestinal constipation, blurred vision, dry mouth, and changes in her voice. She underwent clinical assessment and laboratory tests (biochemical tests, chest X-ray, digestive endoscopy, colonoscopy, chest computed tomography, abdomen and pelvis computed tomography, abdominal ultrasound, and ambulatory blood pressure monitoring). Measurements of catecholamine and plasmatic renin activity were performed at rest and after physical exercise. Finally the patient underwent physiological and pharmacological autonomic tests that better diagnosed dysautonomia.

Abstract Background: Metabolic syndrome (MetS) is widespread among hypertensive patients. Clinical features and potential biomarkers of MetS in the presence of hypertension and resistant hypertension (RHTN) represent a great area of interest for investigation. Objective: The purpose of this study was to evaluate the prevalence of MetS and the clinical features associated with it in resistant and mild to moderate hypertensives. Methods: This cross-sectional study included 236 patients, (i) 129 mild to moderate hypertensive patients and (ii) 107 patients with RHTN. We measured blood pressure (BP) and adipokines levels, and performed bioelectrical impedance analysis. Microalbuminuria (MA), cardiac hypertrophy and arterial stiffness were also assessed. The significance level of alpha = 0.05 was adopted. Results: We found a MetS prevalence of 73% in resistant and 60% in mild-to-moderate hypertensive patients. In a multiple regression analysis, MA (odds ratio = 8.51; p = 0.01), leptin/adiponectin ratio (LAR) (odds ratio = 4.13; p = 0.01) and RHTN (odds ratio = 3.75; p = 0.03) were independently associated with the presence of MetS apart from potential confounders. Conclusions: Our findings suggest that both resistant and controlled hypertensive subjects have a high prevalence of MetS. In addition, MetS-related metabolic derangements may cause early renal and hormonal changes. Finally, LAR may be useful as a reliable biomarker for identifying those hypertensive subjects who are at risk for developing MetS.
