Item Angiotensin‐converting enzyme gene (ACE) polymorphisms are associated with dysregulation of biochemical parameters in hypertensive patients.(2023) Agostini, Lívia da Cunha; Cunha, Warlley Rosa; Silva, Nayara Nascimento Toledo; Melo, André Sacramento; Soares, Luciana Bicalho Moreira; Almeida, Tamires Cunha; Belo, Vanessa de Almeida; Vital, Wendel Coura; Teixeira, Luiz Fernando de Medeiros; Lima, Angélica Alves; Silva, Glenda Nicioli daIntroduction The genetic component, including genes and their variants, plays a signifcant role in the pathophysiology of arterial hypertension (AH). Thus, clinical, epidemiological and genetic studies have been carried out to improve the under- standing of disease mechanisms, improve diagnostic quality and contribute to prevention. Objective To determine the association of risk factors, biochemical parameters and diferent ACE gene polymorphisms with AH. Method The case-control study was carried out in the population of Ouro Preto, Brazil. The subjects answered a question- naire containing clinical and sociodemographic data. The ACE gene polymorphisms rs4291, rs4363 and rs4335 were evalu- ated by real time-polymerase chain reaction (real-time PCR) in 310 people (155 hypertensive and 155 normotensive patients), in addition to biochemical parameters. A multivariate logistic regression model was used to identify factors associated with AH. Analysis of continuous variables was performed using the Kruskal-Wallis test to assess signifcance between groups and Dunn’s post-test for multiple comparisons. Results The results showed that AH was associated with age, education, smoking, obesity and high levels of triglycerides, sodium, glucose and uric acid. Regarding the biochemical parameters, in hypertensive patients, the rs4363 and rs4335 poly- morphisms were associated with high levels of triglycerides, urea and glucose; the rs4291 polymorphism was associated with elevated urea and glucose levels. No association was detected between SNPs and HA. Conclusion AH was associated with socioeconomic status, lifestyle habits and biochemical parameters. ACE polymorphisms may have infuenced the levels of triglycerides, urea and glucose in hypertensive patients.Item High molecular weight adiponectin as a biomarker of hypertension in children and adolescents with obesity.(2023) Cunha, Warlley Rosa; Gaspar, Isabella Campos; Souza, Beatriz Cazarim de; Martins, Bárbara Dias Lana; Miranda, Josiane Aparecida de; Lanna, Carla Márcia Moreira; Santos, José Eduardo Tanus dos; Lacchini, Riccardo; Belo, Vanessa de AlmeidaLower HMW (high molecular weight) adiponectin levels are associated with obesity, insulin resistance, and metabolic syndrome in children and adolescents. However, data on HMW levels in pediatric population with hypertension are lacking. This study aimed to examine the association and predictive capacity of HMW levels, HMW/HOMA-IR, and HMW/APN ratio with hypertension in obese children and adolescents. The 299 pediatric subjects were grouped in obese hypertensive (OH), obese normotensive (ON), and normal weight normotensive (NN). Plasma concentrations of HMW were investigated by ELISA. ANOVA was used to compare study groups, and a binary logistic regression analysis was used to verify if HMW, HMW/HOMA-IR, HMW/APN, APN, APN/HOMA-IR, and HOMA-IR are associated to hypertension regardless obesity in children and adolescents. To compare the strength and performance of each biomarker to classify individuals with and without hypertension, the receiver-operating characteristic (ROC) curve, area under the curve (AUC), and Youden index (J) were evaluated. Both HMW plasma levels and the HMW/HOMA-IR ratio were significantly lower in the OH group when compared to the ON group (HMW: 2.00±1.33 μg/mL vs 2.48±1.48 μg/mL; HMW/HOMA-IR ratio: 0.87±0.95 vs 1.27±1.2; P<0.05) and NN weight groups (HMW: 2.00±1.33 μg/mL vs 4.02±1.99 μg/mL; HMW/HOMA-IR ratio: 0.87±0.95 vs 2.62±1.86; P<0.05). Hypertension was associated with lowest HMW (OR=4.50; 95% CI=1.41–15.84) and HMW/HOMA-IR (OR=12.13; 95% CI=2.51–92.93) regardless of obesity. However, HOMA-IR or the HMW/APN was not significant (P>0.05). In the ROC curve analyses, the HMW and HMW/HOM-IR were more sensitive to detect hypertension in children and adolescents with obesity. Conclusion: Low levels of HMW oligomer and HMW/HOM-IR are associated with hypertension in childhood obesity. Thus, these biomarkers could be clinically useful in identifying hypertension in childhood obesity.Item Longitudinal study of plasma visfatin/nicotinamide phosphoribosyltransferase (nampt) levels in healthy pregnant women.(2023) Nunes, Priscila Rezeck; Cavalli, Ricardo de Carvalho; Belo, Vanessa de Almeida; Sandrim, Valeria Cristina; Luizon, Marcelo RizzattiVisfatin/nicotinamide phosphorybosil transferase (NAMPT) is a novel adipocytokine with potential roles in the patho- physiology of metabolic disorders, including gestational disorders. However, there is no clear interpretation regarding the circulating visfatin levels in a healthy pregnancy. Therefore, we conducted the frst longitudinal study of plasma visfatin levels that followed up healthy pregnant women until the third trimester, including the postpartum period (PPP). The study recruited healthy women with singleton pregnancy who were not using any drug (including tobacco and alcohol). We have excluded pregnant women who did not attend all scheduled exams and developed gestational diabetes or hypertension, obesity, preeclampsia, or any infections during pregnancy. Nine women were considered eligible and examined during all three trimesters of pregnancy and between 8 and 12 weeks postpartum (PPP). Visfatin/NAMPT concentrations were meas- ured in EDTA-plasma by ELISA. The mean age of pregnant women included was 22±5 years (54% primiparous), and the mean of gestational age at delivery was 40±1.2 weeks. Mean systolic and diastolic blood pressures were 90 and 70 mmHg, respectively. Mean values (± standard error mean) of visfatin concentrations (μg/L) during trimesters were 11.38±1.45 (frst, 11–14 weeks), 9.18±1.82 (second, 20–24 weeks), 18.67±2.65 (third, 34–36 weeks), and 10.12±1.49 in the PPP. The value of the third trimester was signifcantly higher than the second trimester, and signifcantly reduced in the PPP (p<0.05, ANOVA with Bonferroni’s multiple comparison tests). Visfatin/NAMPT levels are signifcantly lower in the PPP, suggesting that factors stimulating its production would be limited to pregnancy, thereby contributing to its potential application as a biomarker in pregnancy complications.Item Menores níveis de adiponectina total associados com fatores de risco cardiometabólico em crianças e adolescentes.(2021) Barbosa, Carolina Abade; Rocha, Juliana Leal Maia da; Debossan, Lívia Costa; França, Mayara Valadares Lanza; Guedes, Renata Viana Hoffmann Monteiro; Veiga, Benedito de Oliveira; Lanna, Carla Márcia Moreira; Belo, Vanessa de AlmeidaObjetivo. Associar as concentrações dessa adipocina com fatores de risco cardiometabólicos (IMC, circunferência abdominal, HOMA-IR, TGL, HDL, colesterol e pressão arterial sistólica). Materiais e métodos. Crianças e adolescentes de 5 a 18 anos foram divididos em 3 grupos: 165 crianças/ adolescentes saudáveis, 114 crianças/adolescentes com obesidade e 74 crianças/adolescentes com obesidade/hipertensão. As dosagens de APN total foram determinadas no plasma EDTA pelo método ELISA sandwich. ANOVA foi usada para comparar os grupos definidos pelos quartis de APN total em relação aos fatores de risco cardiometabólicos. Resultados. As crianças e os adolescentes com obesidade/ hipertensão apresentaram menores níveis séricos de APN total (P<0,05). Menores níveis de APN total estão associados a fatores de risco metabólicos (IMC, circunferência abdominal, HOMA-IR, triglicerídeos, HDL, colesterol e pressão arterial sistólica) (P<0,05). Conclusão. Menores níveis de APN total são fatores associados à fatores de risco cardiometabólicos em crianças e adolescentes.Item NAMPT levels are inversely related to nitric oxide formation and positively related to soluble fms-like tyrosine kinase-1 levels in preeclampsia.(2019) Pereira, Daniela A.; Sandrim, Valeria Cristina; Palei, Ana Carolina Taveiros; Santos, José Eduardo Tanus dos; Belo, Vanessa de Almeida; Cavalli, Ricardo de Carvalho; Luizon, Marcelo RizzattiNAMPT is a biomarker for endothelial dysfunction, but its relationship with nitrite (marker of NO formation) and soluble fms-like tyrosine kinase-1 (sFLT-1) has not been previously evaluated in preeclampsia. Therefore, we measured plasma NAMPT and sFLT-1 levels using enzyme immunoassays and plasma nitrite concentrations using an ozone-based chemiluminescence assay. NAMPT was positively correlated to nitrite (r = 0.217; P = 0.034) and inversely related to sFLT-1 (r = −0.340; P = 0.029) in healthy pregnant women, but inversely related to nitrite (r = −0.259; P = 0.035) and positively correlated to sFLT-1 (r = 0.326; P = 0.007) in pre- eclamptic patients, suggesting that NAMPT inhibits NO formation and interacts with the antiangiogenic factor sFLT-1 in preeclampsia.
