ABSTRACT
OBJECTIVE: To evaluate the behavior of acute phase proteins and lipid profile in patients undergoing Roux-en-Y gastric bypass. METHODS: We conducted a prospective study, consisting of three moments: M1 - preoperative (24 hours before surgery); M2 - 30 days after surgery; and M3 - 180 days after surgery. We carried measured height and BMI, as well as determined the concentrations of acute phase proteins (C-reactive protein (CRP), albumin and Alpha-1-acid glycoprotein) and total cholesterol, LDL-c, HDL-c and triacylglycerol. RESULTS: participants comprised 25 individuals, with a mean age of 39.28 ± 8.07, 72% female. At all times of the study there was statistically significant difference as for weight loss and BMI. We found a significant decrease in CRP concentrations between the moments M1 and M3 (p = 0.041) and between M2 and M3 (p = 0.018). There was decrease in Alpha-1-GA concentrations between M1 and M2 (p = 0.023) and between M1 and M3 (p = 0.028). The albumin values increased, but did not differ between times. Total cholesterol and triacylglycerol decreased significantly ay all times. LDL-c concentrations decreased and differed between M1 and M2 (p = 0.001) and between M1 and M3 (p = 0.001). HDL-c values increased, however only differing between M1 and M2 (p = 0.050). CONCLUSION: Roux-en-Y gastric bypass promoted a decrease in plasma concentrations of CRP and Alpha-1-acid glycoprotein, improving lipid and inflammatory profiles.

Objetivo: avaliar o comportamento das proteínas de fase aguda e o perfil lipídico em pacientes submetidos à derivação gástrica em Y-de-Roux. Métodos: estudo prospectivo, constituído por três momentos: M1 - pré-cirúrgico (24 horas antes do procedimento cirúrgico); M2 - 30 dias pós-cirúrgico; e M3 - 180 dias pós-cirúrgico. Foram realizadas aferição antropométrica de peso, altura e IMC, como também determinação das concentrações das proteínas de fase aguda (proteína c reativa (PCR), albumina e alfa-1-glicoproteína-ácida) e de colesterol total, LDL-c, HDL-c e triacilglicerol. Resultados: participaram desse estudo 25 indivíduos, com média de idade de 39,28±8,07, sendo 72% do sexo feminino. Em todos os momentos do estudo observou-se diferença estatística significativa quanto à redução de peso e IMC. Verificou-se diminuição com diferença nas concentrações da PCR entre os momentos M1 e M3 (p=0,041); M2 e M3 (p=0,018). As concentrações da a1-GA reduziram e foram diferentes entre os momentos M1 e M2 (p=0,023); M1 e M3 (p=0,028). Os valores de albumina aumentaram, mas não diferiram entre os momentos. O colesterol total e o triacilglicerol diminuíram com diferença entre todos os momentos. As concentrações de LDL-c diminuíram e diferiram entre os momentos M1 e M2 (p=0,001); M1 e M3 (p=0,001). Os valores de HDL-c aumentaram, entretanto apenas diferiram entre os momentos M1 e M2 (p=0,050). Conclusão: a derivação gástrica em Y-de-Roux promoveu diminuição nas concentrações plasmáticas da PCR e alfa-1-glicoproteína ácida, melhorando o perfil inflamatório e lipídico.

BACKGROUND: Obesity is considered a low-grade inflammatory state and has been associated with increased acute phase proteins as well as changes in serum fatty acids. Few studies have assessed associations between acute phase proteins and serum fatty acids in morbidly obese patients. OBJECTIVE: To investigate the relationship between acute phase proteins (C-Reactive Protein, Orosomucoid, and Albumin) and serum fatty acids in morbidly obese patients. METHODS: Twenty-two morbidly obese patients were enrolled in this study. Biochemical and clinical data were obtained before bariatric surgery, and fatty acids measured in preoperative serum. RESULTS: Orosomucoid was negatively correlated with lauric acid (P = 0.027) and eicosapentaenoic acid (EPA) (P = 0.037) and positively with arachidonic acid (AA) (P = 0.035), AA/EPA ratio (P = 0.005), and n-6/n-3 polyunsaturated fatty acids ratio (P = 0.035). C-Reactive Protein (CRP) was negatively correlated with lauric acid (P = 0.048), and both CRP and CRP/Albumin ratio were negatively correlated with margaric acid (P = 0.010, P = 0.008, resp.). Albumin was positively correlated with EPA (P = 0.027) and margaric acid (P = 0.008). Other correlations were not statistically significant. CONCLUSION: Our findings suggest that serum fatty acids are linked to acute phase proteins in morbidly obese patients.
